If you can get training there <24hrs after delivery mentat 60 caps sale, perform a laparotomy and explore and (or at another special centre) you will not regret it generic mentat 60caps mastercard, but do repair the tear mentat 60 caps line. Certainly purchase mentat 60caps line, though, your best chance of success is in the first Fistulae are usually the result of: attempt; so, do not perform this operation unless you are (1);obstructed labour in a young primigravida (21. Anyone who claims a 100% success rate either has not done many, has selected easier cases, or has not done a proper follow-up. A gracilis flap is easy to learn and can help out in many difficulties: try to get an expert to show you how to do this! Fistula surgery for easier cases does not need special instruments or equipment; good post-operative nursing care is, however, very important but not complicated and you can achieve success even when you have not done such surgery previously. B, pressure against The area where pressure necrosis occurs will be where the the sacrum causing necrosis of the vaginal and anterior rectal wall. Most commonly this is the urethro-vesical junction, but other sites can occur together or individually: juxta-urethral, mid-vaginal, juxta-cervical and intra-cervical. If the head is deeply impacted in the pelvis, get an assistant to push from below, rather than inserting your hand between the foetal head and the lower segment. After Caesarean Section, take care when suturing lower segment tears, and always ask yourself if you have not inadvertently picked up the bladder. Leave a urinary catheter in situ at least 10days after a Caesarean Section performed for prolonged obstructed labour. Ask about menstruation: it often stops after traumatic childbirth, but may suggest a hysterectomy about The first is the most common: if ischaemia is mild, a small which the patient was never informed. Ask if labour was prolonged, delivery difficult the urethra, which becomes closed off, from the bladder and traumatic. Note whether a Caesarean Section was performed, but easy to repair, unless they extend to the cervix (21-20C). The juxta-cervical fistula (21-20D) usually follows a vertical tear in the lower segment at Caesarean Section (21. Ask sympathetically if previous attempts the defect may include the anterior cervix, and encroach at repair have been made: remember patients may try to hide onto the ureteric orifice (21-20E). Note malnutrition, state of hydration tiny (admitting only a probe) to large (>3cm, usually (many patients drink little in order to reduce their wetness), involving most of the anterior vaginal wall and the complete anaemia and the psychological state. Occasionally the fistula may be truly extensive extending to the anterior bladder wall, Dermatitis & pressure sores. If you cannot see any wetness, ask the patient to Take note of the amount of scar tissue: if you find extensive drink plenty of water and re-examine her after 1hr. Note the remaining length of the urethra: the shorter it is and the more scar tissue that needs to be removed, the bigger Urethral orifice. If so, where is it in relation to the urethra and Make sure the patient is well hydrated from the moment you cervix? Section, ask the patient to empty her bladder and then insert There is no indication for pre-operative antibiotics. Introduce a urinary catheter and Long-acting absorbable sutures are ideal: do not use non-absorbable. Place 3 moist swabs well up in the Half-circle 25mm round-bodied needles are best, though J-shaped needles vagina; then insert 50ml slowly into the catheter. A fistula is confirmed You will need an operating table which tilts and has shoulder rests for more nd rd st complex cases. A headlight is very useful; if this is missing, turn the table if the 2 or 3 but not the 1 swab is discoloured with dye. Place the patient, with the buttocks well over the end of the If this 2nd test is -ve, suspect a uretero-vaginal fistula table, in the exaggerated lithotomy position with legs flexed (see above). The nearer the fistula is to the cervix, the greater so do not attempt any difficult cases until you have is the danger to the ureters. You will do your patients and your reputation no good by attempting difficult cases and failing. Only operate juxta-cervical fistulae in multiparous women Do not waste time with futile investigations and treatment: with where you can easily pull the cervix downwards. Check if the urethra is detached from the bladder: (1);Complex fistulae, including those you have difficulty in this case, leave it for an expert. B, Record the size of the fistula and its distance from the external urethral orifice and G, Trim away any vaginal mucosa and scar tissue at the fistula margin. C, Insert artery forceps through the urethral orifice to expose H, Insert 2 corner sutures through the freshened margins of the fistula. E, Steady the anterior vaginal wall with the of the full thickness of the bladder muscle, excluding the mucosa. Keep a simple continue to dissect round to the sides so that you record of patients on their beds: measuring urine output is mobilize at least 1cm beyond the fistula hole (21-21F). Start the anterior dissection with a little extension vertically towards the urethra and complete it right round; then tie the (1) The aim is that the patient is drinking freely, draining right and left antero-lateral flaps to the labia to urine freely and free to mobilize without being wet. The catheter must never block: if this happens, urine will Trim away with scissors any vaginal mucosa and scar tissue emerge alongside the tube or even leak through your (this should be minimal) at the fistula margin (21-21G). The problem Now you have freshened up and exposed the margins of the about drainage bags is that they can fill up (quickly if the fistula, you can start closure from the corners (21-21H). Remove the forceps in the urethra and insert a catheter, The easiest solution is connecting the catheter to a straight and perform a dye test (21-21K) with 50ml of dilute plastic tube that drains freely into a basin or bucket: this has solution. Press over the abdomen or ask the patient to cough the advantage that you can readily see if urine is dripping to see if there is any discolouration. If exposure is poor, perform an episiotomy, on both sides, The urine should be almost colourless. Check if urine is leaking alongside the tube during bladder irrigation: If there is necrotic sloughy tissue, debride this adequately this may suggest urethral dysfunction. Perform a dye test to and review the situation when all the tissues are clean and check your repair or look for a second (missed) fistula. Wash the perineum twice daily, especially where the catheter emerges from the urethra. Remember you will need more generous exposure of the (3) Remove the vaginal pack after 48hrs. You may find the stenosis recurs and needs regular dilation, so keep a careful (4). Do not clamp and unclamp the catheter: this all too frequently leads to If you suspect the ureter to be damaged, you are likely to disaster! Keep the catheter in situ a further 4wks if more urine drains through the catheter than the vagina. Lying in the prone position allows the catheter tip to rest free from the fistula.

As a result of the chronic inflammation 60 caps mentat free shipping, anemia of chronic disease is often present (10 generic mentat 60 caps on-line,11 cheap mentat 60caps with mastercard,34) cheap 60 caps mentat otc. Medication-related effects on biochemical indices of folic acid and iron status are also common. Some medications such as methotrexate also affect calcium and vitamin D status (1719). Dietary and functional assessments should include attention to energy intake and problems related to obtaining, preparing, and eating food. Patients with social support may have a better quality of life, potentially moderating the impact of pain, depression, and physical disability (33). The disease is chronic and characterized by an age of onset before 16 years of joint swelling, heat, and pain and stiffness of unknown origin (10, 11) that occurs for 6 weeks or more (11). Disease characteristics often include inflammation, fever, damage/deformity of joints, and altered bone growth (10). In abnormal bone growth, one bone may be longer than another at times of accelerated growth and later become stunted. If the abnormal bone growth occurs in the leg, the child may compensate by bending the longer leg until the hips are level. Either arm-span or knee-height measurements are appropriate depending on the location of contractures and range in motion of joints. Growth charts for stature for age, weight for age, and weight for stature are important tools for monitoring growth retardation and body composition changes. Biochemical indices for iron-deficiency anemia should be monitored and assessed to determine the cause and intervention for the anemia. Side effects that affect nutritional status include mouth sores, bone marrow damage and altered iron status (10,34), and blood and protein loss in urine (34). Dietary intake and status may be influenced by many manifestations of the disease, and therefore dietary intake is important to obtain. Energy and protein malnutrition may be found in 10 to 50% of children with this disease (11). Jaw function is compromised in the 20 to 30% of children who have abnormal jaw development (10), and a small jaw or teeth misalignment can result in dysphagia (difficulty swallowing) (10,11). Patients may be depressed and embarrassed, negatively impacting their social life (10,11). Gout is more prevalent in men than women (18,19) with an age of onset after 40 years (18,35,36). Women are more likely to develop gout later in life (after menopause) than men, and the upper extremities are more often affected (35,37). Large tophi on the heels may make it difficult to accurately measure a standing height. Alternative methods of estimating height may be required depending on the manifestations of the disease. Central fat distribution may be measured using waist circumference and risk is increased with a waist circumference of more than 100 cm for men 88 cm for women (39). Patients with gout are often prescribed medications for inflammation and uric acid control. Other anti-inflammatory drugs prescribed for gout include colchicine and corticosteroids. About 80% of patients experience side effects of nausea, vomiting, and diarrhea when taking colchicine (35). Nutritional deficiency of vitamin B12, sodium, and potassium are also related to colchicine (18). Central obesity and serum uric acid levels are associated with insulin resistance, hypertension, high serum lipids, and renal failure. When gathering dietary intake data, it is important to determine intake of alcohol, nonalcoholic beverages, and purine- rich foods. Adequate hydration is important if the patient is at risk for renal calculi (18,19). Dietary intake of purine- rich foods may contribute to as much as one-third of the serum uric acid (18,19, 36,39). However, dietary intake of purine-rich foods and the impact on serum uric acid is controversial. Elevated serum uric acid is caused by inadequate renal excretion (90% of the serum level) and excess synthesis (10% (18,19,36,39)). Dietary intake contributes to excess synthesis; thus, dietary intake of purine-rich foods will have relatively little impact on serum uric acid levels. It may still be important to determine intake of purine-rich foods because individuals may be more sensitive to these foods and have a greater reaction, or they may be able to take lower drug doses. These patients may not be able to prepare meals, grip utensils to eat, or even write. Systemic Sclerosis Within the United States, the prevalence of systemic sclerosis is estimated at 240 cases per 1 million adults (40). Both involve fibrosis of the skin but limited scleroderma only includes thickening of the skin in the face and neck and below the elbows and knees. Disease manifestations make it difficult to obtain anthropometric measurements in some patients, particularly those with diffuse disease. It may be difficult to obtain accurate stature measurements if the patient is unable to stand upright. Biochemical indices are also affected by drugs that alter nutritional status of some nutrients, particularly folic acid, the fat-soluble vitamins, and calcium. Enteral or parenteral nutrition may be required if a patient is unable to maintain weight or if a patient has significant intestinal dysfunction (41). Skin fibrosis of the fingers may make it difficult to eat and write or to handle objects in shopping or cooking. Raynauds phenomenon involves vasoconstriction with resulting symptoms of cold hands and feet and changes in skin color on the fingers and toes (25). The patients with moderate to severe Raynauds phenomenon had greater difficulty in performing activities that involved hand use (i. Reduced grip may increase difficulty in preparing food and fibrosis in the face may limit movement of the lips and mouth (25). Hand disability may result from tight skin (43), swelling, hand contractures (25) or ulcerations (25,43); eating dysfunction seems to be the most closely associated hand disability (43). Fecal incontinence (25,41) or urgency (41) may be a sign or symptom of dysfunction in the lower gut. Estimates of its prevalence are unknown (45), but it is estimated to be up to 10 cases per 1 million people (46). The disease manifests with proximal muscle weakness developing in a few weeks or months (4547). The muscle weakness is symmetrical and the pelvis and shoulder muscles are most commonly affected in these patients, but the neck muscles, primarily the flexor muscles, can also become weak and this is found in about 50% of the patients (46).

All mice were then fasted for 17 hours before the diets were initiated in order to establish a similar metabolic starting point cheap mentat 60 caps line. The recommended body weight reduction was 93 achieved and maintained during the dietary treatment period by adjusting the food intake of the R-fed mice every three days 60caps mentat mastercard. At the end of the dietary treatment period the same battery of behavioral tests was performed for each mouse to evaluate the effect of the diet on the behavior of these mice order 60 caps mentat free shipping. All statistical data were 94 presented according to the recommendations of Lang et al buy mentat 60 caps lowest price. Consistent with the well-recognized health benefits of mild to moderate calorie restriction in rodents, no adverse effects were observed in either mouse group fed a calorically restricted diet. Despite a 2023% body weight reduction, all R-fed mice appeared healthy and more active than mice in the groups fed ad libitum, as assessed by ambulatory and grooming behavior. Furthermore, nesting behavior was similar for all dietary groups (empirical observation). It is important to mention that no epileptic seizures were observed throughout this study in the Rett mice. The average daily food intakes for the wild-type and Rett groups over the pre-trial period were 4. All mice lost approximately 8- 13% body weight over the course of the 17-hour fast at the beginning of the treatment period. No significant differences in body weight were observed between the wild-type (29. Influence of Diet on Grip Strength The grip strength test was used to distinguish motor neurodevelopment deficits between the Rett mice and the wild-type control mice. Influence of Diet on Incline Latency The incline latency test measured the ability of a mouse to orient (face upward) itself against gravitational forces when placed facing downward on a o negative 40 slope. No significant differences in the incline latency to face upwards were observed between the wild-type (40. Influence of Diet on Righting Reflex 97 The righting reflex test was used to measure each mouses proprioception and reflex response to revert back on its four limbs after being placed on its back. No differences were found between the Rett and wild-type mice (all mice performed the task within 0-2 sec). Influence of Diet on Visual Placing The visual placing test was used to measure the visual proprioception of the Rett mice. Influence of Diet on the Light-Dark Compartment Test The light-dark compartment test was used to measure the ability or tendency of the mice to explore a novel environment. Influence of Diet on Rotorod Performance The rotorod was used to measure motor development, coordination, and balance in the Rett mice. No significant differences were found between the four groups in the rotorod performance at 60 rpm. These findings indicate that the Rett mice have a motor coordination/balance deficit. Influence of Diet on Open-Field Performance The open-field test was performed to measure motor defects in locomotor activity and rearing events in the Rett mice during a 15 min testing period. Total time and rest time in each zone (center and periphery) was also similar between Rett and the wild-type mice (data not shown). This latter observation further supports our rational for omitting an unrestricted KetoCal mouse group. In contrast, the performance of the Rett mice on the open-field test was not significantly different from that of the wild-type mice. Although this particular finding is not consistent with that previously observed (Shahbazian et al. More specifically, our test was performed for a total of 15 min, whereas Shahbazian et al. In the aforementioned study, the performance of the Rett mice was not significantly different from the wild-type mice after 10 min, but differences were observed at the 20 and 30 min time points (Shahbazian et al. Consistent with prior evidence that the Mecp2 mice display interaction deficiencies (Shahbazian et al. The failure of the Rett mice to explore novel environments may reflect a heightened level of anxiety (Paylor et al. Interestingly, we observed that calorie restricted Rett mice exhibited not only an increased ability or tendency to explore a novel environment (i. It is important to mention that both the light-dark test (the emergence time to the light and the total time spent in the lit environment) and the open-field test (the entry into the center of the open-field apparatus) are measures of anxiety (Paylor et al. As an aside, although nesting is a measure of home-cage activity related to both social behavior and motor function (Moretti et al. In general, R-fed mice spent significantly less time interacting with their nesting material compared to mice fed an unrestricted diet due to a persistent search for food. Furthermore, it is important to mention that since girls with Rett are smaller and have reduced body weights (Thommessen et al. Asterisks indicate that the body weight of the R group mice was significantly +/y lower (P < 0. Asterisks indicate that the grip strength of the Rett mouse groups was significantly lower (P < 0. Diet had no effect on improving the ability of the Rett mice to suspend from the wire. Influence of Diet on Incline Latency (Negative Geotaxis) in Mecp2 308/y and Mecp2 Mice. This latter phenomenon serves as the marketing platform of the high fat, low carbohydrate Atkins diet as a weight loss paradigm (Kossoff et al. Organisms have evolved to sense and adapt to environmental cues for their survival when 124 compromising conditions such as food depletion or various forms of energy stress are present (Vaquero and Reinberg, 2009). The sirtuin family of proteins has been implicated as such a potential evolutionarily conserved mechanism for life span regulation and aging retardation (Blander and Guarente, 2004; Guarente and Picard, 2005; Bishop and Guarente, 2007; Feige et al. Although comparisons of a variety of age/disease- related changes have been made between energy-restricted and unrestricted rodents in an effort to identify the underlying physiological/biochemical neuroprotective process(es) of those diets many studies fail to provide a standardized regimen for diet implementation. We suggest that these diet implementation guidelines, on a working standard calorically restricted paradigm for disease animal models, should not only maximize the therapeutic diet efficacy but also normalize data interpretation for comparison within different animal studies by reducing laboratory artifacts. However, these terms are not synonymous (Table 11), thus one needs to be cautious when studying them (Thompson et al. This probably is due to the influence of both the animal genotype and the age of the animal during diet initiation (Goodrick et al. It is possible that the complex relationship of body weight to life span both between and within the various dietary groups makes it difficult to predict that lower body weight increases survival or that is neuroprotective (Goodrick et al. This finding suggests that rodents exhibit increased food consumption on the fed days in order to maintain similar body weights as those seen in rodents fed ad libitum. Interestingly, this binge-eating phenomenon is also observed upon re- feeding of normal mice calorie restricted for 30 days (Mahoney et al.

According to the Hungarian surgical belief purchase 60 caps mentat with amex, Victor Fischer (an ingenious designer of surgical instruments) was the inventor of the first surgical stapler that was used by Hmr Htl purchase mentat 60caps with amex. In 1912 discount 60 caps mentat with amex, Ramstedt described a new technique to save the life of the infants suffering from spastic hypertrophic pyloric stenosis buy mentat 60caps otc. His electrosurgical unit let the high frequency alternating current pass through the body allowing it to cut or coagulate (electrocautery). With the support of the Charite in Berlin, they opened the Institute of Medical Cinematography. They put a camera above the operating table which was electrically directed and could make films from operations. He was the first who performed a pulmonectomy in a patient who was suffering from bronchiectasia. In order to prevent injuries of the lung while getting through the thoracic wall, Veres used his own new, special, spring- loaded needle to create safely an artificial pneumothorax which was a technique for treatment of the tuberculosis at that time. The instrument (Veres-needle) is spreaded world-wide in creating pneumoperitonuem during laparoscopy. In the Johns Hopkins Hospital, he performed the first successful operation on a cyanotic infant (blue- baby), who had a syndrome of tetralogy of Fallot. The transplanted kidney functioned well at the begining, but they had to reoperate the patient 10 months later, when they found a shrunken and pale kidney graft. This produced an ambivalent opinion in the public: You are dead when your doctor says you are. In 1966, the French Medical Academy for the first time used the irreversible injury to the brain as a factor to establish (determine) the death instead of the cardiac standstill. The donor heart came from a 24-year-old woman, who had been killed in a road accident. Washkansky survived the operation and lived for eighteen (18) days when he died due to a severe infection. Erich Mhe (1938-2005) performed the first laparoscopic cholecystectomy in Bblingen. That time, the German surgical society degradated the method as the keyhole surgery. Friedrich-Wilhelm Mohr (1951- ) using the Da Vinci surgical robot performed the first robotically assisted cardiac bypass in the Leipzig Heart Centre (Germany). In New York Jacques Marescaux used the Zeus robot to perform a laparoscopic cholecystectomy on a 68 year old woman in Strasbourg (France). The human use of the technique promises the reduction of postoperative pain (no pain surgery), the decrease in possibilty for adhesion, and the elimination of postoperative abdominal hernias. Operating theatre Operation All such diagnostic or therapeutic interventions, in which we disrupt the body integrity or reconstruct the continuity of the tissues are called operations. Layout and equipments of the operating room We talk about two types of operating theatres: septic and aseptic ones. In the aseptic operating theatre the danger of bacterial infection does not usually exist (e. The essence of it is: always to prepare the surgical area for the patient in a way that we do not put him (or her) in a danger of infection. Before entering into the operating room, you should change your dresses in the dressing (or locker) room (of the operating complex) and wear the surgical cap and the face mask. The patients are brought into the operating theatre with the help of a specifically used transporting chair or bed- after passing through a separate locker room (of the operating complex). The operating theatre is a 50-70 m room, which does not usually have any windows. The operating complex must be architecturally separated from the wards and the intensive care unit. The operating complex consists of: locker rooms (dressing rooms), scrub-up area, preparing rooms, and opearting theatres. It is equipped with central and portable vacuum system, as well as pipes for gases. Only those people whose presence is absolutely neccessary should stay in the operating room. Activity causing superfluous air flow (talking, laughing, and walking around) should be avoided. Entry into the operating theatre is allowed only in operating room attire and shoes worn exclusively in the operating room. This complete change to the garments used in the operating theatre should also apply for the patient placed in the holding area (i. Movement into the operating room out of the holding area is allowed only in a cap and mask covering the hair, mouth and nose. General rules of asepsis concering the personnal attire Taking part in an operation is permitted only after surgical hand washing and scrubbing. Surgical team members in sterile attire should keep well within the sterile area; the sterile area is limited by isolation. Scrubbed team members should always face each other, and never show their backs to each other. Non-scrubbed personnel should not come close to the sterile field or the scrubbed sterile person, they should not reach over sterile surfaces, and they should handle only non-sterile instruments. Behaviours and movements in the sterile operating room The personnel is always keeping in mind the rules of asepsis while moving: they face each other and the sterile territory (e. Sterile hands must not touch the cap, the mask or the nonsterile parts of the gown. You must not stretch out your hand to attempt to catch falling instruments and you are not allowed to pick them up. Do not take any instrument from the instrument stand; ask the scrub nurse to give it to you. General rules of the aseptic opereating room Only sterile instruments can be used to perform a sterile operation. The sterile instrument will stay so if only the sterile person touch it (or if it comes in contact with only a sterile object). If a sterile instrument comes in contact with an instrument of doubtful sterility, it will loss its sterility. In a wider sense, the asepsis means such an 14 ideal state when the instruments, the skin, and the surgical territory do not contain microorganisms. Antisepsis Includes all those procedures and techniques designed to eliminate contamination (bacterial, viral, fungal) present on objects and skin by means of sterilization and disinfection. Because skin surfaces and so the operating field and the surgeons hands can not be considered sterile, in these cases we can not talk about the superficial sterilization. In a wider sense, antisepsis includes all those prophylactic procedures designed to ensure surgical asepsis. A careful scrub and preparation of the operative site (cleansing and removal of hair) is necessary. In septic and high-risk patients, there is a need for perioperative antibiotic prophylaxis.

It is well known 31 that increased refractive index of the lens in advanced nuclear cataract may cause 32 a secondary myopia; pre-existing myopia may also serve as an independent risk 33 factor (Lim et al buy 60caps mentat. The aggregation of lens protein into 41 randomly distributed high molecular weight clusters are thought to produce suffi- 42 cient fluctuation in protein density to account for the opacification buy cheap mentat 60caps online. The 03 crystallins cheap 60 caps mentat mastercard, which constitute approximately 90% of the total protein content of 04 the lens buy mentat 60caps, accumulate and show many age-related oxidative changes. These include 05 formation of disulfide and other inter- and intramolecular cross-links and methionine 06 oxidation, all of which result in the aggregation of high molecular weight molecules. It may be possible that local or systemic conditions 09 affecting the protein redox status, such as myopia and diabetes, influence this 10 process (Altomare et al. The sulfhydryl proteins, 19 known to have structural and functional role in the crystalline lens, contain an 20 elevated number of thiol groups and, therefore are reduced as a result of oxidation. A significant proportion of lenses and 28 aqueous humor taken from cataract patients have elevated H2O2 levels. Because 29 H2O2, at concentrations found in cataract, can cause lens opacification and produces 30 a pattern of oxidation similar to that found in cataract, it is concluded that H2O2 31 is the major oxidant involved in cataract formation (Ramachandran et al. After exposure to oxidative stress, the redox 39 set point of the single layer of the lens epithelial cells (but not the remainder of the 40 lens) quickly changes, going from a strongly reducing to an oxidizing environment 41 (Ito et al. The female gender 05 has been found to display an increased incidence of cataracts, as compared with 06 age-matched men. This increased risk is seen in woman population after menopause 07 only (Gupta et al. Protective effect of Sex Steroid 08 Hormones in the perspective of cataractogenesis in females has been substantiated 09 by epidemiological information. The Beaver Dam Eye Study suggests a modest 10 protective effect of estrogen exposure on the lenses of women in the context of 11 age related opacities (Klein et al. The results indicated that the current use 12 of post-menopausal estrogens is associated with decreased risk of severe nuclear 13 sclerosis. The study also showed that from menarche to menopause the life span of 14 woman is associated with protective effect and decreased risk of nuclear sclerosis 15 and cortical opacities. Proper ionic 19 milieu and hydration of lens cells are essential to maintain transparency of crystalline 20 lens. Estrogen maintains proper ionic composition by its non-genomic action (Singh 21 and Gupta, 1997a). Further, estrogens are known for increasing water imbibitions 22 and retention of hydration in the target tissues (Singh and Gupta, 1997b). At the molecular level, a number of scavenger molecules are present that 26 protects against oxidative stress. It maintains ascorbate in the reduced state and 33 scavenges peroxides and radiation induced free radicals Vitamin C, always in high 34 concentration in the aqueous is actively transported into the lens, where it is at a 35 higher concentration. Glare is 02 another debilitating symptom of cataract for which an active individual needs to 03 be operated. This happens particularly in context of night driving or even in bright 04 sunlight. The phacoemulsification technique, which allows 10 an exquisite intraoperative control and a consistent closed-chamber removal of 11 cataract, undoubtedly reigns supreme in the developed countries. This technique has 12 brought cataract surgery results as close to anatomical perfection as possible with 13 the current technology and skills. In order to increase safety and to achieve faster 14 visual rehabilitation for their patients, many surgeons are now adopting topical 15 anesthesia with an adjunctive intracameral 1% lidocaine (Shah et al. Understanding 19 the distinctive uses of the newer dispersive and cohesive viscoelastics has helped 20 ensure better corneal endothelial protection during phacoemulsification. Of the wide 21 range of phaco techniques developed to suit different cataracts and their related 22 conditions, recommendations are for those that ensure endocapsular (posterior plane) 23 phacoemulsification, which ensurse far superior long-term outcome. Hydrodisection procedure is then performed to free the nucleus from 31 the capsule. After ensuring a freely rotating nucleus, a wide trench or crater is 32 created which is confined within the area of the capsulorhexis. After achieving 33 sufficient thinning of the nuclear plate (atleast 90% of the total central depth), the 34 phaco tip is buried at 6 oclock, using controlled U/S power, to produce a vacuum 35 seal. The entire nucleus is 38 chopped thus in a step-by-step fashion by rotating the chopped fragment clockwise 39 and repeating the same chop technique. This is followed by foldable 44 intraocular lens implantation in the capsular bag. Although some of these alter- 31 native futuristic techniques are available today, they have not been extensively 32 adopted. This aphoristic concern over the clarity of the posterior capsule 35 shall undoubtedly dominate the future arenas of research and innovation. The use of accommodative material also has a 38 bright future if the absence of capsular opacification can be ensured. The current 39 experimentation and innovation to perfect the chemoemulsification technique may 40 turn out to be and easier alternative. The concept of implanting an intraocular 41 drug delivery device at the end of cataract surgery is in its infancy. Its routine use 42 in future may definitely bring significant relief to a surgeon from the worries of 43 patient compliance and ensure an excellent round the clock postoperative medical 44 control. Consumption of wedges in the central space by stop, chop and stuff technique 23 24 4. Moreover, even where high quality surgery is readily accessible, it may be 31 expensive. It has been estimated that a delay in cataract onset of only 10 years 32 could reduce the need for cataract surgery by as much as half. This section will review existing and possible 34 future strategies to prevent or delay age related cataract. In vitro and animal research has suggested that antioxidant substances 43 present in the diet (Rose et al. This is due to the large number of different antioxidants that have 04 been examined, levels for many of which are likely to be highly colinear across 05 individuals. A prospective follow up after a specific intervention may allows the 06 role of different nutritional factors to be distinguished more readily. Compounds receiving attention as potential 19 anticataract agents include aldose reductase inhibitors (Bron et al. However, none of these agents has 24 demonstrated efficacy in the prevention of human lens opacity in a trial setting. It is clear, however, 27 that challenges to development of a practical anticataract agent for wide human 28 distribution will be substantial: such an agent would need to be sufficiently safe for 29 (presumably) long term use, and sufficiently inexpensive to compete with increas- 30 ingly cheap cataract surgery. It appears very unlikely that a pill or eye drops 31 requiring regular, long term use would be practical or sufficiently inexpensive. Lens opacity was 34 also found to develop on average 12 years earlier among the Indian subjects.

Clinical Presentation Most (90%) patients with gall stone diseases are asymptomatic. Symptomatic patients present with: History: - Right upper quadrant colicky pain (biliary colicky) - Dyspepsia, fatty food intolerance, flatulence, abnormal post prandial bloating - Symptoms of acute cholecystitis or other complications Physical examination: right upper quadrant tenderness Risk factors can be identified 190 Complications of Gall bladder stone 1. In the gall bladder: chronic cholecystitis acute cholecystitis gangrene perforation empyema mucocele carcinoma 2. The main stay of treatment 2) cholecystostomy for bad risk patients with severe infection (Severe Acute cholecystitis or gall bladder empyema) 191 Acute Cholecystitis Definition Acute cholecystitis is an acute inflammation of gall bladder due to obstruction of neck of gall bladder or cystic duct stone. Another rare form of acute cholecystitis which occurs in absence of stone is called acalculous cholecystitis. Pathogenesis Direct pressure of calculus on the mucosa results in ischemia, necrosis, and ulceration with swelling edema and impairment of venous return. This process increases and extends the extent of inflammation and favors bacterial multiplication. The end result may be:- - Pericholecystic abscess - Fistula formation between gall bladder and bowel - Gall bladder empyema/mucocele - Rarely, perforation of gall bladder and bile peritonitis Commonly involved bacterial species in acute cholecystitis include E. Clinical features History: History of chronic cholecystitis or Cholelithiasis Women more affected than men Moderate to severe right upper quadrant and epigastric pain which may radiate to the back.

To emphasize the importance of early diagnosis & intervention Introduction Abdominal wall hernias are common surgical problems encountered in all levels of health care facilities. Adequate knowledge to reach to the correct diagnosis and appropriate management plan help the care provider to prevent serious complications which could be fatal. General consideration Definitions Hernia is a protrusion of a viscus through an opening in the wall of the cavity Important terminologies Hernial sac - is an out pouch of the peritoneum. It has four parts: mouth, neck, body and fundus Content- Is a viscus or any other organ inside a sac. It can be: - Small bowel and omentum the commonest - Large bowel appendix - The bladder Reducible hernia- when the protruded viscus can be returned back to the abdomen Irreducible hernia- when the contents cant be returned back Obstructed hernia- the content of the hernia (intestine) is occluded but no impairment of vascular supply Strangulated hernia- when the vascularity of protruded viscus is impaired Richters hernia- when only one side of the wall of the intestine is herniated. Here strangulation of the bowel can occur with out intestinal obstruction Sliding hernia- when an extra peritoneal structure form part of the wall of the sac 198 Risk factors for abdominal wall Hernia development Increased intra abdominal pressure resulting from: - Chronic cough - Straining at urination or defecation - Heavy wt lifting - Abdominal distension Weakened abdominal wall - Advanced age - Malnutrition - Congenital defect ppv - Trauma/surgery Clinical features History - Lump which varies in size - Pain, local aching, discomfort - Factors predisposing to increased intra abdominal pressure - Symptoms of int. Strangulation is a surgical emergency Risk of obstruction and strangulation is very high in femoral hernia, paraumblical hernia and indirect inguinal hernia with narrow neck 199 Principles of management - Spontaneous resolution is unlikely - The risks of irreducibility, obstruction and strangulation increase with time. So surgical intervention is needed in most cases Surgical treatment for abdominal wall hernias 1. Herniotomy - removal of the sac and closure of the neck: Done only in infants and children 2. Obstruction and strangulation This is one of the causes of intestinal obstruction (acute abdomen). Therefore, one shouldnt forget to examine the hernial sites during evaluation of the patient with intestinal obstruction. Treatment options Non operative treatment: Gentle reduction (Taxis) can be indicated in obstructed hernia in infants but not advisable in adults due to the risk of mass reduction. Inguinal hernia - accounts for 80% of all external abdominal wall hernia - commonest is all ages and sexes - 20 x more common is males than women - more common on right side Classification 1. Direct type : Bulges through the post wall of inguinal canal Indirect inguinal hernia - 60% on right, 40% Lt side and 20% bilateral - Due to congenital defect or potential defect which is the remnant of processes vaginalis - 20 times more common in men Direct inguinal hernia - due to wear and tear associated with advanced age and increased intra abdominal pressure 201 Femoral Hernia - acquired downward protrusion of intestinal contents into the femoral canal - 4 times more common in females (middle-aged multiparous) - rare in children Clinical features History - Elderly or middle aged woman with thin body build - lump on anterior and upper thigh - may present with complaints associated with int. Risk factors Female sex Multiple parities Obesity Ascites Complications Obstruction Strangulation Rupture Treatment Expectant: - Spontaneous closure is expected in 80% cases of umbilical hernia in under five children. Surgery: - Beyond five years 202 Incisional Hernia Risk Factors Wound infection Poor surgical technique (improper facial repair) Chronic cough or straining Obesity Clinical features Risk of obstruction and strangulation is very rare. It had been one of the intersecting points for the discipline of internal medicine and surgery. Gastric cancer is one of the top five cancers in frequency, however, it is one of the disease entities with the worst prognosis because of the difficulty to diagnose it early. Therefore one has to have a high index of suspicion to diagnose the disease early for the outcome of treatment heavily depends on the stage of the disease at the time of diagnosis. Peptic ulcer disease Anatomy and physiology of the stomach and duodenum The stomach is an asymmetric dilation of the proximal gastro intestinal tract. Region Mucosa cells Secretion Cardia goblet cell mucus fundus and body parietal cells acid chief cells pepsinogen Antrum and pylorus goblet cells mucus G. The stomach performs two interrelated functions in the initial phase of digestion a. Food breakdown to form chyme through - mechanical digestion and - acid and pepsin action b. Phases of gastric secretion There are three phases of gastric secretion Cephalic - mediated by acetylcholin secreted by the vagus nerve. Gastric - mediated by the hormone gastrin (by G cells) Intestinal - mainly inhibitory through peptides like secretin Pathogenesis The pathogenesis of peptic ulcer is an imbalance in the aggressive activity of acid and pepsin and the defensive mechanisms that resist mucosal digestion. Classification Acid peptic disease of the stomach and duodenum includes Erosive gastritis (inflammation confined to the mucosa of the stomach) Acute gastritis - occur after major trauma, shock, sepsis, head Injury and ingestion of aspirin and alcohol. Chronic gastritis Peptic ulcers - extend through the mucosa into the submucosa and muscularis. Chronic gastric and duodenal ulcers are distinguished by the presence of an established inflammatory reaction. Duodenal ulcer usually occurs in the proximal duodenum with in 1 to 2 cm of the pylorus, the portion of intestine first exposed to gastric secretion. In duodenal ulcer there is acid hyper secretion while in gastric ulcer acid secretion is either normal or decreased. Clinical manifestation The clinical presentation is non-specific and the following features may not always be found. Table 1: Summary of clinical features of gastric and duodenal ulcers Gastric ulcer Duodenal ulcer Periodicity present Well marked Pain Soon after eating but not when lying Two hours after food down Night pain Vomiting Considerable vomiting No vomiting Hemorrhage Hematemesis more frequent than Melena more frequent than melena hematemesis Appetite Afraid to eat Good Diet Lives on milk and fish Eats almost anything Weight Loses weight No loss in weight On examination it is not unusual to find localized deep tenderness in the right hypo chondrium. However gastric ulcers need endoscopic evaluation and biopsy to rule out malignancy Surgical treatment The patient is referred for surgery in the following conditions: a. Intractability (failure of medical treatment) Complications Overall, in men, there is a 5 percent risk of perforation.
