RESUMO
Bacterial translocation is an important source of pancreas infection in acute pancreatitis. The effect of platelet-activating factor (PAF) in the pathogenesis of acute pancreatitis has been proved in various studies. The aim of this study was to determine whether potent PAF antagonists influence bacterial translocation in acute pancreatitis. Acute pancreatitis was induced in 62 Wistar rats by injection of 2.5% sodium taurocholate into the biliopancreatic duct. The rats treated with PAF factor antagonists received intravenous injection of WEB-2170 (10 mg/kg), lexipafant (5 mg/kg), and BN-52021 (5 mg/kg) 30 minutes before induction of acute pancreatitis. Six hours after induction of acute pancreatitis, bacteriologic cultures and histologic scoring of tissues were performed. There was a statistically significant reduction in bacterial translocation to the mesenteric lymph nodes and liver but not to the pancreas of the rats treated with PAF antagonists. No significant increase in the intestinal bacterial population of any group was found. There were no statistical differences between the pancreatic histologic scores of the groups. PAF antagonists reduced bacterial translocation to distant sites other than the pancreas, preventing the bacterial dissemination that occurs in the early phase of acute pancreatitis and may have beneficial effects on the evolution of this disease.

Sixty-eight patients born with a myelomeningocele were studied in the second and third decades of their lives. All of them had had some orthopaedic surgery, an orthotic program, and other specialized medical and paramedical services. In the group with sacral-level lesions, half were community ambulators; in the group with lower lumbar lesions, a third; in the group with upper lumbar lesions, a tenth; and in the group with thoracic-level lesions, none. The most important factors that determine the ambulatory status of a child with myelomeningocele, besides the level of the lesion, are the motor power within a given neurosegmental level and the extent and degree of orthopaedic deformities.

One hundred and fifty patients with a displaced fracture of the ankle caused by external rotation-abduction forces were treated by open reduction and rigid internal fixation. After an average follow-up of three and one-half years, the results were satisfactory in 90 per cent. Less satisfactory results were noted in the more severely injured ankles. We found that the ruptured deltoid ligament did not need to be repaired if the lateral side was anatomically and rigidly fixed; in the Maisonneuve fracture, restoration of the fibular length was as important as stabilization of the fracture; with the use of the suprasyndesmotic screw, walking was permissible with the screw in situ; conforming the plate to the bend of the lateral malleolus was essential; and as much as two millimeters of lateral residual displacement of the lateral and medial malleoli was compatible with a satisfactory result, as was a similar displacement of the talus provided there was anatomical restoration of the lateral side.

The role of total gastrectomy in adenocarcinoma of the stomach has been controversial due to the high morbidity and mortality rates associated with the procedure. A retrospective analysis of all total gastrectomies performed for adenocarcinoma of the stomach, between January 1975 and December 1986 at the Tata Memorial Hospital was undertaken to evaluate the results and establish the usefulness of the procedure.

Partial and total amputation are well-accepted procedures for the surgical treatment of carcinoma of the penis. In certain cases after adequate amputation the residual penile stump is too small from the penoscrotal junction to offer useful function, and a total amputation is therefore usually performed. In such cases a subtotal amputation with reconstruction of the penile stump avoids a perineal urethrostomy and permits micturition in the erect posture.

Tuberculosis infrequently involves pancreas. The clinical features in patients with pancreatic tuberculosis are usually non-specific. The radiological features mimic pancreatic malignancy or pancreatitis. Ultrasound or CT scan guided fine needle aspiration cytology or biopsy may show caseating granulomatous inflammation. The present report includes two cases of pancreatic tuberculosis and review of relevant literature. One of our patients was diagnosed at laparotomy and the other with a CT scan guided fine needle aspiration cytology. Both patients responded well to anti tubercular chemotherapy and are now asymptomatic.

Symptom control is the essence of palliative care but is not without problems, especially in the difficult socio-economic conditions of a developing country. We present our experience with over 2000 hospice admissions over six years in India's first hospice, to highlight our problems and the measures we have taken to solve them. The prevalent habit of tobacco smoking and chewing in India gives rise to a high incidence of head and neck cancers which form 50% of our admissions. Another 24% is formed by breast and gynaecological cancers. The difficult symptoms in head and neck cancers are pain, dysphagia, fungation and trismus. Almost 25% of our head and neck cancers have feeding tubes, which we feel are justified and most useful for medication and basic nutrition. Difficult problems in gynaecological cancers are pain, chronic blood loss, ulcerations and fistulae. The inadequate or sporadic availability of oral and injectable morphine adds to our problems in pain control. Non-compliance of patients to take adequate medications and the resistance from relatives make it sometimes difficult to achieve optimum symptom control. India has many systems of alternate and unorthodox medicine. We find that these are best tried outside the hospice unless they are in fully-studied clinical trials. In the end there is always the difficult choice of either remaining in the hospice for optimal symptom control or going back to their homes, where this may not be available.

This study aims at knowing the behaviour of the family facing the home accidents among children, identifying the risk factors in the home environment, in the family's perception and analysing the socioeconomic-cultural context contributing to the occurrence of children's home accident. The work was made in a family that had experienced a case of poisoning of a 4 year-old child. Participant observation and the semi-structured interview were used as methodology. The results evidenced that the family constantly lives among children's home accidents and the socioeconomic-cultural context has a strong influence in the amount and quality of these cases.

The study's proposal was to evidence a bibliography review about children' accidents. The bibliography and documental researches were used as methodology. The data made clear that children accidents are the bigger public health problem in England. In the United States, in 1989, had happened about 2,700 deaths as accident results in children under 14 years old. In Brazil has been registered high index of attendance at pediatric emergencies that involves home accidents. It has been concluded that these cases have been increasing and they need special attention and preventive approach.

The presence of veterinary products in the houses without any minimum security procedures has led to a poisoning case for a one-year old child who developed a serious systemic reaction. This child was interned at a Pediatric Intensive Care Unit at a public hospital in Fortaleza, Ceara. This study aims at identifying the family reaction facing a poisoning of a child and analyzing these reactions, interpreting its social cultural context. It has been developed as an ethnographic study case, consisting of the exploration, decision and discovery phases. It has been observed through the results that the family recognizes the existence of risk factors in home environment but does not adopt any coherent preventive methods with this experience. We do believe that these occurrences reduction demand transforming educative actions which may lead the family to be conscious towards the problematic that concerns poisoning for children, occurred under their responsibility.
