OBJECTIVE: To describe the case of an infant with Hirschsprung's disease presenting as total colonic aganglionosis, which, after surgical resection of the aganglionic segment persisted with irreversible functional intestinal obstruction; discuss the difficulties in managing this form of congenital aganglionosis and discuss a plausible pathogenetic mechanism for this case. CASE DESCRIPTION: The diagnosis of Hirschsprung's disease presenting as total colonic aganglionosis was established in a two-month-old infant, after an episode of enterocolitis, hypovolemic shock and severe malnutrition...

Hepatic portal gas (HPG) has historically been associated with high (75% or over) mortality rates related to abdominal dramatic conditions and has served as an indicator for urgent exploratory laparotomy. Over the last two decades, the greater availability and higher speed of use of CT as well as improvement in the management of critically ill patients have increased the sensitivity of imaging HPG. HPG has been found associated with a broad range of diseases, some of which are benign and do not necessarily require urgent exploratory laparotomy in the absence of signs of intra-abdominal acute condition or systemic toxicity...

Traumatic shock is a complex phenomenon that represents the culminating element of a series of events. It is, in fact, the outcome of an imbalance-decompensation of the organism's defence mechanisms, in which the oxygen supply to the mitochondria is hampered by a macro and/or microcirculation failure. Basically, it is a form of hypovolemic shock in which further factors have a role, including the activation of inflammation mediators. It should also be stressed that part of the cellular damage is caused by tissue reperfusion...

BACKGROUND: There is pre-clinical evidence, involving several animal species, suggesting that opioid peptides play a role in the physiopathology of shock (endotoxic, hypovolemic, cardiogenic, spinal, anaphylactic). Many case reports have suggested that naloxone (an opiate antagonist) might be an effective treatment for shock in humans, but others have not supported such a point of view. This controversy led us to undertake a meta-analysis of the available evidence on the efficacy of naloxone as a treatment measure of shock in humans...

Widespread destruction of the skin induces a large necrotic mass and a break of the skin barrier. It also leads to an intense inflammatory reaction. This activates keratinocytes, endothelial cells and neutrophils. Certain mediators (e.g. endothelin, histamine, bradykinin, serotonin, catecholamines, vasopressin, prostaglandins, cytokines and nitrogen monoxide) are thus released in large quantities and act both at the site of the burns and at a distance. The abnormally high level of albumin in the capillary wall and the increased capacity of absorption of the interstitial areas around the burns are the main abnormalities observed...

The acute occlusion of the popliteal artery involves: 1. A regional disease: muscular ischaemia with an increase of capillary permeability and oedema. The recovery of the circulation brings with it the formation of free radicals. 2. Sometimes, a general and metabolic illness complicates the muscular ischaemia. It associates to varying degrees: hypovolemic shock, metabolic troubles, acute renal failure, disseminated intravascular coagulation, infection. It can compromise the vital prognosis. The reanimation which completes the surgical treatment includes two stages: 1...

Fifty-two clinical charts of children who had been discharged from this hospital, after being treated for acute renal failure, were analyzed to determine the incidence, presentation and results of the treatment used. We found that 0.7% of the total number of children admitted developed this complication and that 4/5 of them were under two years old. The initial illnesses were gastroenteritis, bronchial pneumonia, cyanogenic cardiopathies and sepsis. Some of the patients had hypoxic episodes or went into hypovolemic shock or a combination of both...

The physiopathological aspects of traumatic hypovolemic shock (T.H.S.) are described. On the basis of clinical and biochemical diagnostics, suitable T.H.S. resuscitation and therapeutic measures can be undertaken. The principles of treatment of T.H.S., as applied at the U.K.H. of Linz are then set out. Intense cooperation between anesthetist and traumatologist, as shown by this short note, is the clearest demonstration of what medicine can do today in the field of traumatology.

Three new viruses have been identified in Africa during the present decade. They may cause sporadic cases or limited outbreaks, and they are probably endemic in areas which are still ill-defined. Severe forms of infection lead to the haemorrhagic syndrome or to hypovolemic shock, the physiopathology of which is being studied. The case-fatality ratio of severe cases is between 30 and 85 per cent. Nosocomial outbreaks have been observed, but they can be avoided if appropriate barrier nursing measures are carried out for the treatment of patients or adequate protection measures for sampling and examination of laboratory specimens...
