In the gall bladder: chronic cholecystitis acute cholecystitis gangrene perforation empyema mucocele carcinoma 2 buy 250 mg sumycin fast delivery. 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 generic sumycin 250 mg line. 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. Differential diagnosis Perforated or penetrated peptic ulcer disease Biliary colic Pneumonia Pancreatitis 192 Hepatitis Pleurisy Appendicitis Myocardial ischemia or infarction.

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.

Epigenetic memory and preferential lineage-specic differentiation in induced pluripotent stem cells derived from human pancreatic islet Beta cells. Generation, purication and transplantation of photoreceptors derived from human induced pluripotent stem cells. Platelets generated from human embryonic stem cells are functional in vitro and in the microcirculation of living mice. At that time, the biochemical nature of genes was unknown as well as their role as repositories and transmitters of the genetic information. Waddington imagined the epigenetics as a conceptual model to explain his theory sustaining that different interac- tions between the genes and their surroundings (or, we could say their environment) could result in different phenotypes, starting from the same genetic material. He used the metaphor of the epigenetic landscape to explain the biological development. Waddington stated that cell fates were established during the development similarly to a stone (a marble) that rolls down from high places to the point of lowest local elevation; the increasing irreversibility associated with cell-type differentiation was imagined as due to ridges, rising along the slope where the stone is rolling down, directing the marble into different valleys [1]. More recently, Holliday dened epigenetics in a more formal way as the study of the mechan- isms of temporal and spatial control of gene activity during the development of complex organisms [2]. Specic combinations of epigenetic modications determine the conformation of the chro- matin ber, thereby having the possibility to regulate the transcriptional potential of the associated genes. Despite the advances in our knowledge about cell differentiation and epigenetic phenomena, and with the unavoidable adjustments and corrections, Waddingtons model still represents a nice visualization of the epigenetics. As a matter of fact, it appears really useful to suggest that aging processes are particularly prone to epigenetic mechanisms. The notion Waddington could not know, indeed, was that once differentiation has been completed (i. To resume and apply Waddingtons model to the aging, we can imagine that erosive processes can change the shape of the slope and of the surroundings of the stone, causing the reprise of its rolling down through new ridges and valleys. According to this view, the terminally differentiated cell is subjected to environ- mental stimuli (originated either from the organism itself or from the external environment) able to induce changes in gene expression through epigenetic mechanisms. The higher the mountain, the longer the slope; consequently, the stone encounters many more possibilities to be subjected to changes of directions and shape. This view recalls the idea that a longer life (of 520 a cell or organism) is associated with a more frequent probability that epigenetic changes arise, possibly causing aging-associated dysregulation. On the basis of this metaphoric view, aging (and aging-associated diseases) represents the inevitable companion of a long life. In the present chapter, evidences related to the connection between epigenetics and aging are presented and discussed in the light of the most recent advances in this eld of biomedical research. Particular attention is devoted to the aging brain, which appears to be the organ most interesting in normal and pathological aging processes, due to the relevance of neuro- degeneration among the age-associated diseases and to the recent scientic evidences indi- cating substantial involvement of epigenetic phenomena in brain aging. Probably, being faced daily with aged and diseased patients negatively inuences the humor and mood of clinicians and researchers working on aging, but the sentence is undeniably correct. Indeed, humans cannot escape (as far as we know) aging and, in that case, aging-related diseases [4]. These improvements contributed not just to the increase in average life expectancy but also, in many cases, to reach and spend the oldest age in better physical and cognitive condition than in the past. Despite this progress in life expectancy, it is interesting to note that almost no progress was observed for the oldest age that it is possible to reach (the maximum lifespan potential); moreover, in association with the increased life expectancy, many (and sometimes new) diseases show an increased morbidity dependent on aging [6]. The existence of a genetic determinant of life duration is supported by the apparent impos- sibility of going beyond a certain maximum lifespan potential and also by the observations indicating that this potential seems to be determined and characteristic for each species. This information induced the theory that even if we could cure or prevent the diseases most responsible for human death, we will be able to just further extend life expectancy, but wont be able to signicantly overcome the maximum lifespan potential determined by the advent of fatal age-associated physiological impairment [7]. The study of the picture representing the age-associated diseases is complicated by the possible early start of the pathological mechanisms, possibly initiating in early age, and also by the above-cited differ- ence in the regulation of aging mechanisms in different organisms, which makes it difcult to use surrogated animal models to study human aging. A list of the principal theories explaining causes and possible mechanisms of aging is reported here [8,11]: 1. Evolutionary: evolution presses the organisms to reach the reproductive age, procreate, and care for the offspring. According to this point of view, the physiology of an organism after the end of the reproductive period could be the manifestation of the epigenetic events occurring on the basis of the genetic development during the previous stage of the life. The conclusion is that cellular senescence could be the price to pay in order to avoid other damage, like tumorigenesis, potentially caused by the prolonged expression of the genes involved in the reaching of reproductive tness [12]. Protein modication: the worsening of the enzymatic activities in aging could be a consequence of the altered postsynthetic modications, altered turnover and proteins cross-linking [13]. Oxidative stress: this is one of the most investigated areas of cellular senescence; the involvement of free radicals and the alteration of the oxidative status in aging has been characterized in several models and organisms and in different pathologies associated with older age, like Alzheimers disease and Parkinsons disease. The balance between pro- and antioxidants in the cell is nely and complexly regulated and the impairment of this regulation is critical to mitochondrial, cellular, and tissue physiology during aging [14].

These were her initial test results: mercury and thallium, both Positive at teeth, breast and lymph nodes. Rhodanese enzyme Negative at the breast, should be Positiveit is a detoxifying enzyme. She was being challenged continuously by this endogenous carcinogen (20-methylcholanthrene)! And iron was low due to competition with copper [and germanium] from a tiny bit of metal or plastic left somewhere in her mouth. Clostridium botulinum, Clostridium sporogenes, Rhizobium leguminosarum, Rhizobium meliloti were all Positive at the breast. She brought it in for review, not quite believing the radiologists Span- ish comments which she thought translated to He could not find it! She sang it qui- etly to the staff before leaving: Not Only Smaller But Gone to the tune of I Wish I Were Single Again. This was a case of early discovery of a developing tumor, using Syncrometer technology. It was January 15, and he had already been on the herbal program for two weeks, as well as zapping. In spite of this, he tested Positive for isopropyl alcohol when he arrived; he couldnt stop using his favorite supplements. In the last two years he was getting up six or seven times a night to empty his bladder. He was given environmentally safe lodging with a restaurant nearby that could prepare malonate-free food and properly sterilized uncol- ored dairy products. He had seven or eight root canals, at least four bridges, and some crowns in his mouth. He had a lively person- ality, full of humor, but he could not express it due to low energy. The calcium level was much too low, which is evidence of toxins in the parathyroid. But nothing was extremely high or low, and if we could improve his nutritional status while removing his body burden of toxins, he would be successful in dissolving his tumor. He laughed with anticipation of new found health; he called the mo- tel/restaurant his paradise, but he was happy to just rest! We scheduled him for dental work to extract every tooth that had a large metal or nonmetal filling. After ten years of a failing battle with prostate cancer, switching to dentures was not a big price to pay. And the calcium level had risen to normal, showing that toxins were now out of the parathyroid. The problem had now shifted to the thyroid which can be seen in the potassium level (5. He was trying to eat fat and drink milk (carefully selected and treated) for the first time in years. But first he must do another panoramic X-ray to guarantee there were no leftover bits of amalgam in his jaws and mouth tissues. Lactoferrin was now testing Positive at the bone marrow; he was drink- ing raw milk that had been tested for dyes and sterilized. He had not been hot packing enough and was immediately helped with this important task. But uric acid was extremely low, showing that clostridium bacteria were still swarming somewhere. His body was thriving on improved nutrition, malonate-free and safe from parasite eggs, unsanitary bacteria, and carcinogenic dyes. He was Chloride 95 95 99 99 ready to start rebuilding triglycerides 46 59 85 200 the prostate gland. Calcium and uric acid were still too low, implying bacteria in the para- thyroids; they should be searched for. He was instructed to help his bowel function with Lugols enemas once a day, just to get the bacterial level down. If the adjustment was not carefully moni- tored, the materials used could re-pollute the teeth. Sucking on a carcinogen day and night is far more injurious than occasion- ally eating it.
