A renal cancer has density similar to or slightly higher than that of normal renal parenchyma but has a thick wall which is more significant cheap tegretol 400mg without prescription. The most frequent causes of indeterminate results from ultrasound are (i) a mass in the upper pole of the kidney order 100 mg tegretol otc, (ii) a mass in the region of the renal pelvis tegretol 400mg mastercard, (iii) presence of multiple renal masses and (iv) markedly obese patient order 200mg tegretol. Conventional static B scan and real time instruments also visualize the bladder and prostate with the patient supine. Any change of renal outline and diaplacement or fragmentation of the collecting system of echoes is of pathological significance. In case of haematuria, even if the intravenous urogram is normal, ultrasound can detect a peripheral lesion that does not deform the calyceal system or renal outline. Renal sonography should be followed by percutaneous puncture (under sonographic visualization). If aspiration reveals clear fluid and the area is smooth-walled as demonstrated in X-ray following injection of a contrast medium, no further investigation is required. Sonography is about 95% accurate in distinguishing between solid and cystic renal masses. Even exact position of a small calculus can be determined during operation by the application of a transducer direct to the kidney surface. The transrectal approach is useful in detecting early asymptomatic tumours of the prostate and in accurately staging local disease of the prostate. The tracing is in three segments — segment A (vascular phase) with a steep rise lasting 20-30 seconds due to the arrival of radioisotopes in the vascular bed; segment B (secretory phase) lasting for 2-5 mins. In renal hypertension the rise is too little (segment A) and prolongation of third phase. This test is not so efficient to determine the function of kidney as the previous test, but in injury, it shows the portion of kidney affected and supersedes the previous test to determine the type of operation to be required. Still it may be used to know the local extent of bladder, prostate or kidney malignancies. It is elevated in prostatic carcinoma with metastasis (10 units or more), but not so as long as the growth remains confined to the gland. It comes from the cancer cells but does not enter circulation as long as the capsule of the prostate is intact. When metastasis in bone occurs in prostatic carcinoma its level is elevated in the serum. It is well recognized fact that osseous metastasis in prostatic carcinoma is osteosclerotic, rather than osteolytic in character. This is also used to exclude pulmonary tuberculosis in suspected cases of renal tuberculosis. Very often bone marrow aspiration from the sternum or ilium reveals carcinoma cells even before the radiological evidence of metastasis. In carcinoma of the prostate, secretion obtained by prostatic massage may show cancer cells (exfoliate cytology). As the ureters are angulated as they pass over the fused isthmus, urinary stasis and stone formation are the usual complications. Horse-shoe kidney is as such asymptomatic and only presents when the above complications appear. Infantile polycystic kidney disease is an hereditary autosomal recessive condition and is often fatal in the neonate. Adult Polycystic Disease is an autosomal dominant condition and typically presents in mid-adult life (30 to 40 years). When an adult presents with bilateral renal swellings with dragging pain in the loin and haematuria in about l/4th cases, the case is one of polycystic kidney. Patients with congenital cystic kidney pass abundant urine of low specific gravity (1. So polycystic kidney in adult is presented with one or more of the following features — (i) Abdominal swelling (enlarged kidney); (ii) Pain (due to enlargement of kidney); (iii) Haematuria (present in 25% of cases); (iv) Infection (presents with pyelonephritis); (v) Hypertension; (vi) Chronic renal failure. If intravenous urography fails to delineate the pelvicalyceal system properly, retrograde urography should be advised. It must be remembered that one side should be performed and the other side is deferred for a week as oedema may impair the renal function and if performed in both sides in one go there is every possibility of anuria. Similar deformity may be seen in renal cell carcinoma but in this case the spider legs are smooth and not irregular as seen in this carcinoma. Moreover in this condition the deformity is seen in both sides whereas in renal cell carcinoma the deformity is unilateral. In chromocystography there will be considerable delay in excretion of indigocarmine in the affected side. Renal swelling with or without dull ache in the loin is the usual presenting symptom. Filling defect of one or more calyces, which are actually stretched over the cyst, is the main abnormality detected. It may be exacerbated by drinking excessive amount of water or alcohol or by taking diuretics. Sometimes the pain may be referred to the epigastrium, when it may be mistaken for duodenal ulcer. If pelvis and calyces are not seen properly retrograde urography should be called for. The earliest change is seen either in the renal pelvis or minor calyces according as the renal pelvis is extrarenal or intrarenal. Decreasing concavity and later on flattening of the minor calyces are the early changes in case of intrarenal pelvis. Gradually there will be dilatation of the major calyces and convexity (clubbing) of the minor calyces. Ultrasound scanning is also quite confirmatory, moreover it is the least invasive. It may be used to detect this case due to pelviureteric junction obstruction in utero. Isotope renography may be used to detect dilatation of the renal collecting system due to obstruction. Whitaker test is sometimes used in specialised unit to monitor intrapelvic pressure by percutaneous puncture of the kidney. Majority of the patients suffer from fixed dull ache in the angle between the lower border of the last rib and the lateral border of the sacrospinalis. This pain gets worse on movement like running, jolting and climbing up the stairs and gets better with rest. Ureteric colic is sometimes felt particularly when the stone obstructs the pelviureteric junction. Pyuria is sometimes noticed but it must be remembered that increase in the number of white cells may be found in urine even in the absence of infection. Tenderness can be elicited either in the renal angle or during bimanual palpation. Patients may present with other gastrointestinal symptoms or may present quite late with supervening infection or uraemia or during X-ray examination of the abdomen for some other complaints.

Preoperative Preparation Inguinal Approach If there are signs of intestinal obstruction tegretol 200mg otc, initiate nasogastric suction 100mg tegretol overnight delivery. The inguinal approach is essentially identical to the McVay When a patient has symptoms suggestive of a femoral hernia repair described in Chap discount tegretol 100mg amex.

For the low groin approach, after opening the sac and reducing its contents, amputate it. It is not necessary to close Pitfalls and Danger Points the neck of the sac with sutures (Ferguson).

This maneuver obliterates the femoral canal but leaves an opening of 6–8 mm adjacent to the femoral vein. Equally Operative Strategy good results can be obtained if the femoral canal is obliter- ated by inserting a plug of Marlex mesh. The technique Choose the operative approach (low groin, high inguinal, or avoids all tension on the suture line. A low groin To reduce an incarcerated femoral hernia, an incision approach under local anesthesia is an excellent choice for the may be made to divide the constricting neck of the hernial sac. If hem- orrhage is indeed encountered during this maneuver and the artery cannot be ligated from below, control the bleeding by finger pressure, and rapidly expose the inner aspect of the pelvis by the Henry approach, which involves a midline incision from the umbilicus to the pubis, after which the peritoneum is swept in a cephalad direction to expose the femoral canal from above. It should be empha- sized that this complication is so rare it does not constitute a significant disadvantage of the low approach to femoral herniorrhaphy. If the sutures drawing the inguinal ligament down to Cooper’s ligament must be tied under excessive tension, abandon this technique. Then insert a plug of nonabsorbable mesh to obliterate the femoral canal, as described below. Carry the incision down to the external oblique aponeurosis and the inferior aspect of the inguinal ligament. Identify the hernial sac as it emerges deep to the inguinal ligament in the space between the lacunar ligament and the common femoral vein (Fig. Often the peritoneum is covered by two or more layers of tissue, each of which may resemble a sac. When the bowel or the omentum remains incarcerated after opening the sac, incise the hernial ring on its medial aspect by inserting a scalpel between the sac and the lacunar ligament (Figs. After returning the bowel and the omentum to the abdominal cavity, amputate the sac at its neck. Although it is not necessary to ligate or suture the neck of the sac, this step may be performed if desired (Fig. Using a peanut sponge, push any remaining preperitoneal fat into the abdominal cavity, thereby clearing the femoral canal of all extraneous tissues. The needle is then passed through the inguinal ligament and through Cooper’s ligament in one simultaneous motion. Cooper’s liga- ment is indistinguishable from the periosteum overlying the cephalad aspect of the pubic ramus. An alternative method involves placing the stitch through the inguinal ligament and then positioning a narrow retractor in the femoral canal to take a bite of Cooper’s ligament and pectineus fascia. Identify the com- mon femoral vein where it emerges from underneath the inguinal ligament, and leave a gap of 4–6 mm between the femoral vein and the most lateral suture (Fig. If strangulated bowel requiring resection is encountered after opening the hernial sac, make a second incision in the midline between the umbilicus and the pubis. Elevate the peritoneum from the pel- vis by blunt dissection until the iliac vessels and the femoral hernial sac are identified. Incise the constricting neck of the femoral canal on its medial aspect and reduce the strangulated bowel. After resecting the bowel, irrigate the femoral region with a dilute antibiotic solution, and repair the femoral ring from below as already described. Monro, who strongly favored the low groin approach, emphasized that the sutures should be tied loosely so they form a lattice- work of monofilament nylon. The same end can be accomplished even more simply by inserting a rolled-up plug of Marlex mesh as advocated by Lichtenstein and Shore. After the hernial sac has been eliminated and all the fat has been cleared from the femoral canal, insert this Marlex plug into the femoral canal. The diameter of the plug may be adjusted by using a greater or lesser length of Marlex, as required. Insert the needle first through the inguinal ligament, then through the Marlex plug, and Anesthesia finally into the pectineal fascia or Cooper’s ligament. General or regional anesthesia with good muscle relaxation After the two sutures have been tied, the plug should fit is required. After irrigating the wound with a dilute antibiotic solution, check for complete hemostasis Incision and then close the skin incision without drainage.

Mobilizing the Hernial Sac If the femoral hernia is incarcerated, it is possible to mobi- lize the entire pelvic peritoneum except for that portion incarcerated in the femoral canal (Fig. If the her- nia cannot be extracted by gentle blunt dissection around the femoral ring, incise the medial margin of the femoral ring, and extract the hernial sac by combining traction plus exter- nal pressure against the sac in the groin. Although the pres- ence of an aberrant obturator artery along the medial margin of the femoral ring is a rarity, there may be one or two small venous branches that require suture-ligation prior to incising the medial margin of the ring. If strangulation mandates bowel resection, enlarge the incision enough so adequate exposure for a careful intes- tinal anastomosis may be guaranteed. If bowel has been resected, change gloves and instruments before initiating the repair.

This distinguishes acute lymphadenitis from a malignant growth as the former is extremely painful whereas the latter is painless unless in late stages when there may be nerve involvement buy tegretol 400 mg without a prescription. A swelling in the submandibular triangle particularly seen during meals with pain is due to calculous obstruction of the duct of the submandibular salivary gland tegretol 100mg cheap. Enlargement of the left supra-clavicular lymph nodes is an important sign so far as the cancer of breast and cancer of many abdominal organs are concerned buy 400mg tegretol fast delivery. The branchial cyst* * Branchial cyst develops from the buried ectodermal pouch formed under the 2nd branchial arch which overlaps the 3rd and the 4th and fuses with the 5th generic tegretol 100 mg overnight delivery. A branchial fistula is formed if this pouch communicates with the exterior due to failure of fusion. So structures developed from the 2nd branchial arch lie superficial to this fistula whereas structures developed from the 3rd and 4th branchial arches lie deep to this fistula. In the submandibular triangle, besides lymph nodes, there may be enlarged submandibular salivary gland and deep or plunging ranula. A dermoid cyst occurs in the midline of the neck, either in the most upper part giving rise to double chin or in the most lower part in the space of Burns. Cystic hygroma is commonly seen in the posterior triangle of the neck in its lower part. Sometimes in the lower part of the posterior triangle one may look for the prominence of a cervical rib. A carotid body tumour lies under the anterior margin of the sternomastoid at the level of bifurcation of the common carotid artery, i. The swellings which are adherent to the larynx and trachea move upwards on swallowing, e. Tuberculous and malignant lymph nodes when they become fixed to the larynx or trachea will also move on deglutition. Tuberculous sinus or ulcer arising from bursting of caseous lymph nodes is not uncommon in the neck. Puckering scar may also be found on the skin after healing of these ulcers or sinuses. Sinus due to osteomyelitis of the mandible is usually single and lies a little below the jaw, whereas multiple sinuses over an indurated mass at the upper part of the neck would suggest actinomycosis. A branchial fistula is seen just in front of the lower This is due to infiltration of the skin and platysma 3rd of the anterior border of the sternomastoid by the carcinomatous growth. When there is a swelling, the condition of the skin over the swelling should be carefully noted. Skin may be infiltrated by the malignant growth and the skin is stuck down to the growth causing a fold of skin to stand out above it. These are sometimes present around malignant tumours especially the lymphosarcoma. There may be torticollis in case of acute cervical lymphadenitis or tuberculous lymphadenitis or in case of sternomastoid tumour. Enlarged lymph nodes may also press on the nearby nerves to cause wasting of the muscles. Natural tendency of the patient is to extend his neck while the clinician starts palpating the neck. The head is also flexed passively towards the side of the swelling for proper palpation. A carotid body tumour or an aneurysm can be moved across but not along the line of the carotid artery. To test both sides simul­ taneously, put your hand under the point of the chin and ask him to press down against resistance when both sternomastoids are put into action. If the swelling lies deep to the muscle which is a common occurrence, it disappears under the taut muscle either completely or partially depending on the size of the swelling; the Figs. If the swelling is situated superficial to the muscle, it will be more prominent and movable over the contracted muscle. Whether the swelling has involved the neighbouring structures such as the larynx, trachea, oesophagus, Fig. Relation A malignant growth lying just below the angle of the of a swelling with sternomastoid muscle is quite jaw may involve the hypoglossal nerve and lead to important in the examination of the neck. This is done by pinching the overlying skin off the tumour or by gliding the overlying skin over the tumour. Skin is often involved in case of malignant lymphatic growths and in case of certain benign conditions e. In case of pulsatile swellings one should differentiate between transmitted pulsation and expansile pulsation. In case of aneurysm of the carotid artery there will be expansile pulsation, whereas a tumour in front of the carotid artery will give rise to transmitted pulsation e. Cystic hygroma is a brilliantly translucent swelling, whereas branchial cyst or cold abscess are not translucent, so transillumination test is also important in case of a swelling of the neck. A system should be maintained to palpate all the groups of lymph nodes in the neck. It may be started from below with supraclavicular group, then moving upwards palpating the lymph nodes in the posterior triangle, jugulo-omohyoid group, jugulodigastric, submandibular, submental, preauricular and occipital groups, (a) In case of enlargement of lymph node one should examine the drainage area for inflammatory or neoplastic focus, (b) Other groups of lymph nodes lying in other parts of the body should also be examined in case of enlargement of cervical lymph nodes. Care must be taken to minimise forceful movements of the neck as sudden death is on record following examination of movements of the neck in this condition from dislocation of the atlanto-axial joint (the dens pressing on the medulla). Special investigations will be carried out along the lines discussed in chapter 3 and 8. X-ray is helpful in the diagnosis of the caries of the cervical spine and cervical rib. A radio-opaque fluid (uropac) may be injected into a branchial fistula to determine its extent. In case of secondary malignant lymph nodes (a) Laryngoscopy if laryngeal carcinoma is suspected, (b) bronchoscopy, if bronchial carcinoma is suspected, (c) X-ray chest and mediastinoscopy if mediastinal growth or lung cancer is suspected, (d) Oesophagoscopy and barium swallow in oesophageal cancer and (e) mammography in case of breast cancer may be performed to come to a definite diagnosis. For clinical diagnosis the swellings of the neck may also be divided into acute and chronic swellings. Brief descriptions of the important swellings of the neck are described below : Lymph node swellings. Of the lymph node swellings, tuberculous lymph nodes, carcinomatous lymph nodes (secondary) and various types of lymphoma comprise major components in this group. The pathology passes through various stages and has been discussed in detail in chapter 8. Later on the whole node enlargement due to tuberculosis, matted mass liquifies and "cold abscess" develops deep to the deep cervical fascia. Fluctuation can be elicited with difficulty at this stage due to the presence of tough fascia superficial to the abscess. In a very late stage the deep cervical fascia gives way forming a "collar stud" abscess. In the last stage, the skin over the swelling becomes inflamed and the abscess finds its way out through a sinus which refuses to heal.

If the tendon nodules are found cheap tegretol 200 mg without prescription, pressure on these nodules aggravates pain and novocaine injection relieves the pain tegretol 200mg without prescription. Neurological signs are usually absent generic tegretol 400mg line, but if present they indicate disc prolapse buy generic tegretol 400mg on line. The symptom is pain, which starts in the back and radiates down one or both lower limbs. According to various nerve root/roots affected, various dermatomes of the lower limb may show diminished sensation. Knee jerk or ankle jerk may be diminished or absent according to the root affected. These tumours only become evident when they cause spinal compression by pressing on the anterior surface of the cord. Occasionally they may present as palpable swelling, particularly when the tumour affects the neural arches. The malignant lesions which often metastasise to the vertebral column are : Breast carcinoma, prostatic carcinoma, hypernephroma, bronchogenic carcinoma, thyroid carcinoma in order of frequency. Majority of these secondary deposits are carried by blood vessels from their primary sites to the vertebral column. There is a rich venous plexus in the extradural space and around the vertebral bodies which often carry directly the malignant cells from their primary sites. The common examples of such metastasis are from carci­ noma prostate and carcinoma breast. Majority of such lesions are osteol­ ytic, except a few from carcinoma of the prostate which may be of osteosclerotic type. Collapse of vertebra is not uncommon in osteolytic lesion when it has destroyed considerable portion of the vertebral body. One malignant tumour directly invades the vertebral column and that is malignant neuroblastoma of the sympathetic chain. Occasionally deposits may develop painlessly till there is sudden collapse of the affected vertebra or vertebrae producing severe acute backache and sudden paralysis. Any patient above 40 years of age when complains of backache, should be investigated properly to exclude secondary deposit in the spine. Examination of the spine is also important though it should be done with utmost gentleness. Localised tenderness and abnormality of the alignment of spinous processes are important diagnostic features of secondary metastasis in the spinal column. As the spinal cord ends at the lower level of the first lumbar vertebra, the spinal segment does not correspond to the vertebrae (see Fig. In the cervical region the spinal cord segment is one above in number than the corresponding vertebral spine i. In the upper thoracic region the spines are two lower in number than the corresponding cord segment i. In the lower thoracic region the spines are three lower in number than the corresponding cord segment that is 8th spine corresponds to the 11th thoracic cord segment. In the 1st lumbar vertebral canal all the distal segments of the cord lie as the spinal cord ends at the lower border of the 1st lumbar vertebra. When it is secondary to the breast carcinoma or prostate carcinoma, treatment is mainly hormone therapy. Stilboestrol works in secondaries of prostate carcinoma, whereas adrenalectomy and oophorectomy are good for secondaries of breast carcinoma. Support to the spine with plaster jacket and analgesics are also required as adjuvant measures. Intrathecal phenol (5% in myodil) injections are quite helpful in relieving agonising pain. Operation of laminectomy with decompression of the cord and excision of as much of the tumour as possible may be performed in cases of unrelieved pain with deteriorating neurological state. But this is an extreme step and when the patient’s general condition is already poor, one must not add to the burden of suffering without definite chance of improvement. Extradural tumours, which are situated outside the duramater but inside the spinal canal. Extramedullary tumours, which constitute about 80% of these tumours and which are situated outside the spinal cord and 2. Intramedullary tumours, which coustitute only 20% of these tumours and are situated within the spinal cord. Neurofibromas are common in males and usually arise from posterior nerve roots, so situated in the posterolateral aspect of the spinal cord. These tumours gradually become extradural and may even find their ways through the intervertebral foramina to reach outside the vertebral column. Usually 3 varieties are detected — (i) gliomas, (ii) ependymomas and (iii) vascular malformations. The other tumours are lipoma, angiolipoma, liposarcoma, Schwannoma and meningioma and other primary bone tumours e. The main difference is that in the non-structural group the vertebrae are not rotated and the scoliosis is transient and not fixed. The diagnostic feature is that the scoliosis disappears when the patient sits down. Short stemomastoid, ocular disorders and abnormalities of the chest may also cause compensatory scoliosis of the cervical and thoracic region. Depending on whether the prolapse is pushing the nerve root laterally or medially there may be scoliosis towards the affected side or towards the normal side respectively. In this condition there is always rotationof the vertebra in the fashion that the bodies rotate towards the convexity of the curve and the spinous processes rotate towards the concavity. There are usually three curves — the middle one is known as the primary curve and is the main scoliosis. The above and below the main curve are the compensatory curves which later on also become fixed. In case of structural scoliosis the deformity gradually worsens till the spinal growth of the individual ceases. This is due to the fact that greater pressure is probably exerted through the epiphyses on the concave site, this minimises growth on this side and so increases the deformity. From outside there may be a pad of fat, dimple, excess hair or angiomas associated with such congenital deformities. Neurological manifestations are not seen in congenital scoliosis except when it is associated with spina bifida. Unbalanced paralysis, particularly of the lateral abdominal muscles and intercostal muscles cause scoliosis. Such scoliosis usually appears some years after the original disease and gradually increases progressively. Characteristic pigmentation of the skin known as Cafe-au-lait spots are usually always present to diagnose such condition. Such scoliosis is more often seen in adolescents which may affect any area of the spine. Sometimes idiopathic scoliosis is seen in infants, when the primary curve is always thoracic.

To diagnose endocarditis, 2 major criteria are required: positive blood cultures and abnormal echocardiogram. If 1 of the major criteria is absent, 1 major plus 3 minor criteria will constitute a diagnosis. Treatment decisions for infective endocarditis should be based on the identification of the organism found in blood culture and its specific antimicrobial sensitivities. Prior to the results of blood cultures, therapy can be started if the patient is very ill or there is very clear evidence of endocarditis such as fever, a clearly new or changing murmur, and embolic phenomena. Acceptable empiric therapy would be a combination of an antistaphylococcal drug such as nafcillin (or oxacillin), a streptococcal drug such as penicillin (or ampicillin), and gentamicin. Vancomycin and gentamicin are the standard empiric treatment for infective endocarditis. Therapy of Specific Microorganisms Causing Endocarditis Note the criteria for surgery in infective endocarditis. Prophylactics are indicated when there is both a serious underlying cardiac defect and a procedure causing bacteremia. The man has developed a red skin lesion that resolved and was followed by the onset of facial palsy. On the basis of animal studies we know that the tick needs at least 24 hours of attachment to transmit the Borrelia burgdorferi organism. Erythema migrans rash at the site of the bite (80% of patients) An erythematous patch, which may enlarge in the first few days, may have partial central clearing, giving it a “bull’s-eye” appearance, although this is not commonly seen. The problem with serologic testing is that it often does not distinguish between current and previous infection. Also, in early disease when patients have the rash, testing is often negative because patients have not had sufficient time to mount an immune response. In such circumstances, treatment should be given based on strong clinical suspicion, and serologic testing should not be done. Erythema-Migrans – Lyme Disease Centers for Disease Control and Prevention, James Gathany Clinical Recall Which of the following is an indication for prophylactic therapy in the management of infective endocarditis? The most common areas are the mid-Atlantic coast, upper South, and Midwest of the United States. More common in spring and summer Triad: abrupt onset of fever, headache, and rash (erythematous maculopapules). This disease starts at wrist and ankles and spreads centripetally (can involve palms and soles). In most developing countries, including Africa, Asia, and Latin America, heterosexual transmission is the primary mode. Bronchoscopy with bronchoalveolar lavage for direct identification of the organism. Alternative therapy for mild- moderate disease is a combination of dapsone and trimethoprim or primaquine and clindamycin or atovaquone or trimetrexate (with leucovorin). Pentamidine—pancreatitis, hyperglycemia, hypoglycemia Steroids are used as adjunctive therapy for any patient with severe pneumonia. Ganciclovir—neutropenia or foscarnet-renal toxicity Cidofovir—renal toxicity Prophylaxis. A ubiquitous atypical mycobacteria found in the environment; mode of infection is inhalation or ingestion. Principal Diagnostic Tests Blood culture Culture of bone marrow, liver, or other body tissue or fluid Treatment. Brain biopsy is occasionally necessary if there is no shrinkage of the lesions with treatment for toxoplasmosis. Principal Diagnostic Tests Lumbar puncture with initial evaluation by India ink and then specific cryptococcal antigen testing. Amphotericin intravenously for 10–14 days at least (with flucytosine), followed by fluconazole orally for maintenance and supressive therapy. This is because the incidence of cryptococcal meningitis is too low to demonstrate a mortality benefit with its use. The following is an approximate breakdown of when the risk of certain diseases begins to increase. Monitoring of viral load is the best method to monitor adequate response to therapy when the patient is on antiretroviral medications and the goal is undetectable viremia. High viral loads indicate a greater risk of complications of the disease and a worse prognosis. Sensitivity testing should also be done if a patient is failing a combination of medications and a change in therapy is necessary. It should also be done in any pregnant woman who has not been fully suppressed on the initial combination of medications. Protease inhibitors: hyperlipidemia, hyperglycemia, and elevated liver enzymes for all in the group; abnormal fat loss (lipoatrophy) from the face and extremities with redistribution of fat in the back of the neck and abdominal viscera can be seen. Viral sensitivity testing should be done in all patients prior to staring treatment. Patients present with hypokalemia, hypophosphatemia, metabolic acidosis, and glycosuria. Tenofovir has 2 formulations: alafenamide (preferred, with fewer side effects) and disoproxil. When starting medication, a drop of at least 50% of viral load in the first month is expected to indicate adequate therapy. Pregnant women should get triple antiretroviral therapy (as do nonpregnant people). This is more effect than using condoms (and on the exam, would be the correct answer over using condoms). Treat with mefloquine or atovaquone/proguanil (for Plasmodium falciparum) Treat with chloroquine or primaquine (vivax and ovale only) (for non- falciparum) If severe, treat with artemisinin, not quinine Dengue: transmitted by mosquitos Clinical presentation includes bone pain (back) and retro-orbital headache. Tonic spasms of voluntary muscles; respiratory arrest; difficulty in swallowing (dysphagia); restlessness; irritability; stiff neck, arms, and legs; headache; lockjaw; flexion of the arms and extension of the lower extremities; and high mortality rate. Treatment is prophylactic: Tetanus toxoid (Tdap) boosters every 10 years Immediate surgical care, débride wound Antitoxin, tetanus immunoglobulin Penicillin 10–14 days Wound Management Patient Not Tetanus Prone Tetanus Prone Linear, 1 cm deep cut, without Blunt/missile, burn, frostbite, 1 cm deep; devitalized tissue, without devitalized tissue present + contaminants major contaminants, <6 hours (e. Invasive pulmonary 90% have 2 of these 3 risks: 1) neutropenia <500, 2) steroid use, and 3) cytotoxic drugs (e. Depends on the type of disease being caused; however, all can have an abnormal chest x-ray and Aspergillus in sputum. Allergic bronchopulmonary elevation of markers of allergy/asthma, such as eosinophil/IgE levels Positive skin testing Mycetoma: abnormal sputum culture/serum precipitins/x-ray Invasive: Sputum culture not sufficient; biopsy to show invasion necessary. Allergic: steroid taper and asthma medications, not antifungals Mycetoma: surgical removal Invasive: Voriconazole is superior to amphotericin; there are fewer failures seen with it (and caspofungin) as compared with amphotericin. Proteinuria may be caused by glomerular or tubular disease, although glomerular disease leads to greater amounts. Any positive urine dipstick for protein should be followed up by a quantitative study.

These are (i) blood loss from other injuries, (ii) airway obstruction and inadequate ventilation, (iii) hypoinfusion, (iv) meningitis etc. It cannot be over-impressed that deterioration of level of consciousness should be assumed to be due to intracranial haematoma and cerebral compression unless proved otherwise. In monitoring the patient the points to differentiate cerebral concussion from cerebral compression should be remembered. These are : Cerebral concussion Cerebral compression (0 Unconsciousness from the time of injury. If acute extradural haemorrhage is suspected, surgery should be advised without any special investigation. Importance of skull X-ray on arrival of a case of head injury cannot be over-emphasised. A tangential view including a Towne’s projection may be helpful in case of depressed fracture to know the amount of depression. It should be borne in mind that it is harmful to move the head in different positions for the purpose of taking plates. For further special investigations the patient should be transferred to the neurosurgical clinic. It is wise to give osmotic diuretics (described later in this section) to achieve temporary improvement during transfer. Obviously the presence of haematoma may be indicated by shift of the cerebral midline to the opposite side. The problem of detecting the midline clearly is always there and even with the experienced observers. It plays an important role to demonstrate extracerebral haematomas (extradural or subdural). The technique consists of injection of a dye (10 ml of 35% diodone) into the common carotid artery followed by skiagraphy immediately. It should be said in the passing that this investigation can only be performed when the patient’s condition is not so acute and he does not require immediate operation, as this is a time consuming investigation. Carotid angiography will indicate the presence of subdural haematoma by displacement of the cortical vessels away from the inner table of the skull. In case of extradural haemorrhage the middle cerebral artery will be displaced inward and the anterior cerebral artery will also be displaced to the opposite side across the midline. If there be subtemporal haematoma or subcortical bleeding in the temporal lobe, the middle cerebral artery will be displaced upward. Measurement of intracranial pressure has a clear role in the management of patients with head injuries particularly with intracranial haematomas. But the expertise needed to measure intracranial pressure accurately may not be available in many institutions. Its particular value is in postoperative care after the haemorrhages have been operated on. Its value in indicating the type of haemorrhage and its site before operation is still very doubtful. It should be remembered that an extremely high intracranial pressure may shut off cerebral blood flow. It conveys much more informations about the intracranial contents than any previous technique. The patient lies on a movable couch, so that the part to be investigated can be moved within the scanning gantry. The information is fed into a computer and it produces a record in which high density objects e. It also demonstrates lesions such as contusions and presence of tumours, infarctions, ventricular displacement and hydrocephalus. Its major importance lies in detecting clots in atypical positions, which arc always missed in other investigations. This investigation has become also Valuable in chalking out a rational and coordinated strategy for head injury management. The various drugs which are used in this respect are the osmotic diuretics, steroids, hyperventilation and barbiturates. This is given intravenously to an adult in a volume of 250 ml over the course of 20 to 30 minutes (0. The students are hereby cautioned about the potential dangers of the use of such intravenous mannitol. Care must be taken to see that (i) satisfactory renal function is maintained, (ii) fluid and electrolyte replacement should be accurate and (iii) if the blood becomes hyperosmolar, the rate of administration should be minimised. Students are further cautioned against indiscriminate use of this agent in all cases of head injury. This should not be used in the acute stage when possioility of intracranial haemorrhage has not been excluded. But in certain cases to get more time before surgery, such agent may be used with care. In high doses they have been used in head inj ury cases (Dexamethasone or Betamethasone in the dose of 60 mg/day). But even at present there is no clear evidence that steroids do improve the outcome of head injury cases. Although hyperventilation has been used frequently in Western Countries in head injury cases, there is no convincing evidence of its value. On the whole the effectivity of various medicines just described above in head injury cases is still debatable. Whenever possible intracranial haematomas should be evacuated as expeditiously as possible and the rest is treated with a high standard of intensive care.

The combination of these two factors may result in contusion of the abdominal contents buy 100 mg tegretol otc, detachment of the gut from its mesentery and less commonly rupture of solid viscera order 200 mg tegretol with visa. In suspected injury to the kidney and pelvic bones enquire whether the patient has passed urine or not order tegretol 100mg on line. If the patient has passed blood mixed with urine generic tegretol 400 mg otc, chance of injury to the kidney should be kept in mind. If the patient shows intense desire to pass water but no urine comes out, instead a few drops of blood comes out, extraperitoneal rupture of the bladder or rupture of the membraneous urethra is the most probable diagnosis. If the patient has not passed water and has no intention to do so, possibility of intra-peritoneal rupture of bladder should be kept in mind. Signs of hypovolaemia out of proportion of external injury, if blood in the chest can be excluded, is an almost cardinal indication for opening the abdomen. Bruise, laceration or perforating wound is the external sign of injury which one may locate on careful inspection and injury to internal organ may be at the depth of this external wound. There will be absence of abdominal movements in respiration due to peritonitis from perforation or due to internal haemorrhage. Generalized distension of the abdomen occurs in internal haemorrhage or in late case of peritonitis. Umbilicus may be bulged due to distension of the abdomen caused by internal haemorrhage, late cases of peritonitis, intraperitoneal rupture of the urinary bladder and paralytic ileus. When adhesion of the surrounding viscera and greater omentum succeed in keeping the peritonitis localized, there will be localized tenderness. When the internal bleeding is localized there will be localized tenderness and when the internal bleeding is generalized, there will be generalized tenderness. Rebound tenderness can only be elicited when the parietal peritoneum is inflamed or irritated due to internal haemorrhage. The abdominal muscles in the vicinity of the irritant parietal peritoneum go into involuntary spasm, leading to muscle guard. Generalized muscle guard occurs when there is generalized peritonitis or when internal bleeding has spread all over the peritoneal cavity. Voluntary muscular rigidity means rigidity of the abdominal musculature brought about by the patient himself due to fear of being hurt during examination and also indicates abdominal injury underneath but no parietal peritonitis. Such swelling may be present due to subcapsular haematoma of the spleen or liver, or distended bladder in rupture of posterior urethra. There may be bruise with haematoma affecting lumbar region which should arouse suspicion of renal injury. Similarly bruising with haematoma affecting lower ribs should arouse suspicion of liver or splenic injury according to the side of injury. In case of rupture of anterior urethra there will be perineal swelling or swelling due to extravasation of urine. Shifting dullness test becomes positive when there is free fluid inside the peritoneal cavity. This may occur from internal haemorrhage without localization, in late case of generalized peritonitis, ascites etc. But this examination should be repeated as it takes sometimes for disappearance of bowel sound after injury to the viscera. Auscultation of the chest may indicate presence of bowel sound in case of rupture of the diaphragm. The spine and pelvis (compression test) must be examined properly to exclude any injury here. Patients often complain of abdominal pain in case of injury to the intercostal nerves (T7 to T12). Fluid in the rectouterine or rectovesical pouch indicates free fluid in the peritoneal cavity, intraperitoneal rupture of urinary bladder and intraperitoneal haemorrhage. In many cases you will find that no definite clue can be received in the first examination, but characteristic signs appear later to clinch the diagnosis. X-ray chest to exclude thoracic injury and presence of abdominal viscus in case of rupture of diaphragm. Straight X-ray of the abdomen particularly in sitting position may reveal gas under the diaphragm — a definite sign of rupture of a hollow viscus. Loss of psoas shadow may be helpful in the diagnosis of retroperitoneal effusion of blood. Even in case of intraperitoneal haemorrhage one can find a bigger blurr gap between the air-fluid intestinal loops. Individual circulations are outlined by selective catheterization in case of hepatic, splenic, renal and superior mesenteric arteries. Particularly in delayed rupture of the spleen, the diagnosis is established much before and operation can be undertaken earlier which would otherwise have been postponed until actual rupture has taken place. First of all this test should only be ventured by those who are very much experienced in doing this test and secondly a negative result does not exclude intra-abdominal injury. Fluid should be sent for physical, chemical, microscopic and bacteriological examinations. After a few minutes this fluid is aspirated out and examined thoroughly to come to a diagnosis. Crush injuries may occur in run-over accidents or fall of heavy objects on the abdomen. Seat-belt injury is also included in this group in which during driving a car sudden break will cause the trunk and viscera to move forward with the abdominal wall and become decelerated against the seat-belt and compressed against the spinal column behind. There may be even detachment of the gut from the mesentery and contusion of the abdominal contents. In this type of injury the peritoneal cavity is exposed outside and peritonitis is almost inevitable. The intra-abdominal organ which may be injured by such injury depends on the site of this penetrating wound. As for example stab injury to the right upper quadrant of the abdomen may injure the liver. This often causes internal haemorrhage and/or peritonitis from injury to the hollow viscus. Internal haemorrhage produces certain general signs which are common for injury to any viscus inside the abdomen. In case of internal haemorrhage, increasing pallor, restlessness, small thready pulse, deep and sighing respiration (air-hunger), subnormal temperature and collapse are the general signs. Liver injury may occur as a result of a penetrating wound by stabbing or bullet injury. Right lobe is more commonly injured (5 : 1) than the left lobe as it is less mobile and large. Occasionally when the central part of liver is ruptured bleeding occurs into the large radicles of the biliary tree so that liquid blood is carried along the bile passages into the duodenum and there is haematemesis. Scanning with radioactive isotopes like colloidal gold or "Technetium may detect injury to the liver. Straight X-ray may show increased haziness around the liver region and the diaphragm becomes immobile.
