Standard chemotherapy for disseminated germ cell tumors (GCT) cures most patients but causes considerable acute toxicity, including treatment-related death due to septicemia during neutropenia and pulmonary fibrosis. In addition, chronic and delayed toxicities, particularly Raynaud's phenomenon, have been reported in 6% to 37% of treated patients. In an attempt to minimize the acute and chronic effects of treatment which are related primarily to vinblastine and bleomycin, a randomized trial comparing the efficacy and toxicity of vinblastine + bleomycin + cisplatin + cyclophosphamide + dactinomycin (VAB-6) and etoposide + cisplatin (EP) was conducted on 164 eligible patients with good-prognosis GCT. Seventy-nine of 82 (96%) patients receiving VAB-6 and 76/82 (93%) receiving EP achieved a complete remission (CR) with or without adjunctive surgery. Similar proportions of patients in both arms were found at surgery to have necrosis/fibrosis or mature teratoma. With a median follow-up of 24.4 months in the VAB-6 arm and 25.9 months in the EP arm, the total, relapse-free, and event-free survival distributions were similar in the two arms. Patients receiving EP experienced less emesis (P = .05), higher nadir WBC (P = .06) and platelet counts (P = .01), less magnesium wasting (P = .0001), less mucositis (P = .09), and no pulmonary toxicity. No treatment-related mortality was observed. EP is an efficacious and less toxic regimen and is recommended for good-prognosis patients with disseminated GCT.

Hypokalemia and hyperkalemia are common problems that may be artifactual, iatrogenic, or due to altered body homeostatic mechanisms. ECG may help one to recognize hyperkalemia but not hypokalemia. Excessive K supplementation is a common iatrogenic cause of hyperkalemia whereas fluid therapy is a common cause of iatrogenic hypokalemia. The most common causes of spontaneous hyperkalemia are renal failure and hypoadrenocorticism whereas the most common causes of spontaneous hypokalemia are vomiting, diarrhea, and renal wasting. Symptomatic therapy is usually done until the underlying cause(s) is resolved.

Animals with renal failure have a number of fairly predictable metabolic abnormalities. They are commonly presented to the veterinarian in a state of negative water balance, although prior fluid therapy in an oliguric patient may result in overhydration. Animals with oliguric ARF have sodium retention; those with polyuric ARF have increased urinary sodium loss. Chronic renal failure does not necessarily affect the ability of the renal tubule to conserve or excrete sodium, although the response to changes in sodium load is much slower than in the normal animal. Potassium retention occurs in oliguric ARF and potassium wasting in polyuric ARF; potassium balance is approximately normal in animals with CRF. Both ARF and CRF cause metabolic acidosis, although the acid-base status in a given animal will be affected by respiratory compensation, as well as other problems such as vomiting. Calcium levels are usually normal to slightly decreased in renal failure, whereas phosphorus levels are generally increased. The basic principles of fluid therapy should be used when constructing a plan for such therapy in an animal with renal failure. Intravenous administration of fluids is almost always necessary. The choice of the type of fluid, solutes, and electrolytes to be administered is based on the predicted abnormalities associated with renal failure as well as the laboratory abnormalities in the animal. Careful monitoring of the patient and periodic assessment of various laboratory parameters are necessary in order to make appropriate adjustments in fluid therapy.

Apart from the classic distal renal tubular acidosis (RTA), the proximal RTA, and a few cases of distal RTA and renal bicarbonate wasting we know only 2 cases of infantile transient distal RTA with bicarbonate wasting. A 3 month-old male patient is admitted because of deficient suction, vomiting and dehydration. Despite a strong metabolic acidosis (pH 7,09, bicarbonate 8,6 mMol/l, chloride 110 meq/l) the urine is constantly alkaline; clinically the disease manifests itself in the form of an alkali-resistant RTA. Accompanying troubles such as inner ear deafness, G6PDH deficiency, hyperparathyroidism and vitamin D intoxication are to be excluded. A bicarbonate study carried out with care so as to prevent extracellular fluid expansion reveals the lack of excretion of titratable acid (-2.4 to +4.7 mueq/min/1.73 m2), an reduced excretion of ammonium (5 to 24.8 mueq/min/1.73 m2) with regard to GFR (42.4 ml/min/1.73 m2), and a constant loss of bicarbonate (FE HCO3- about 10%) covering most of the bicarbonate plasma concentration, which results in a constantly negative net acid excretion. Even with alkalosis there is no urine minus blood pCO2 increase. The renal excretion of gamma GT is significantly reduced. On substitution with high quantities of bicarbonate (10 meq/kg BW/day) the defect heals up at the age of 13 months. The pathogenesis of this disease is not quite clear, but is similar to that of the Lightwood infantile RTA. The acidification defect may be explained by a deficient hydrogen ions--secretion in the distal tubule; as for kinetics, it is not in the proximal tubule that the bicarbonate wasting occurs but it may be due to increased sodium delivery to the distal nephron.

Clinical findings, symptoms and predisposing factors were studied in 43 patients with oesophageal candidiasis, 40 patients with peptic oesophagitis and 40 normal controls. Oesophageal candidiasis was confirmed cytologically. 2.4% of patients who had undergone gastroscopy had oesophageal candidiasis; only three of them had simultaneous candidiasis of the oral cavity. Cardiac failure, oesophageal varices, hiatus hernia and gastric ulcer were common associated disorders. 42% of patients with candidal oesophagitis were symptom-free. Most common symptoms were vomiting, retrosternal and epigastric pain. Peptic oesophagitis was more frequently associated with symptoms. Predisposing factors were present in 88% of cases of oesophageal candidiasis: alcoholism, hepatic cirrhosis, diabetes mellitus, malignant tumours and other wasting diseases. 18 patients had had treatment with cimetidine; they included all 13 patients whose candidiasis was first detected at check endoscopy.

Two adolescent patients with eating disorders and severe weight loss presented with neuromyopathy. The first was female and had a twenty months' history of bulimia nervosa with weight loss and episodic gorging and vomiting. The second was male with a two-year history of anorexia nervosa characterised by vegetarianism and increasing food restriction. Both had severe wasting and asymmetrical weakness of proximal limb muscles. The first patient deteriorated on refeeding and became temporarily paralysed. Both had a purpuric rash and haematological abnormalities. They made a complete recovery on a mixed diet: vitamin supplements were given to the first but not to the second patient.

Three cases of benign duodenocolic fistula are presented, and the diagnosis and treatment reviewed. Patients with benign duodenocolic fistulas usually complain of diarrhea, and occasionally nausea and feculent vomiting. Physical examinations are nonspecific, revealing wasting from the chronic diarrhea. Barium enemas are usually diagnostic. Therapy consists of excision of the fistula and repair of the duodenal and colonic defects.

Hemagglutinating encephalomyelitis virus (HEV; also designated vomiting and wasting disease virus) was inoculated oronasally in 26 colostrum-deprived pigs. Anorexia and vomition were seen after an incubation period of 4 to 6 days. In pigs killed during the incubation period or within 2 days after the onset of the clinical signs, HEV could be isolated regularly from the tonsils and the respiratory tract, irregularly from the digestive tract, rarely from the blood, and never from lymph nodes and spleen. The brainstem almost always contained virus after clinical signs appeared, but was only one positive during the incubation period. Olfactory bulb, cerebrum, cerebellum, and vagal nerve were also frequently virus positive in pigs which were ill when killed. The results of the examination by immunofluorescent antibody technique indicated that HEV multiplies in the epithelium lining the respiratory tract and the tonsillar crypts, in neuroepithelium of the nasal mucosa, and in neurons of the digestive tract. The neuronotropism of HEV was also shown by the presence of fluorescence in the perikaryon of neurons in the brainstem and in the trigeminal ganglion without the involvement of other cell types. The presence of viral antigens in the perikaryon of trigeminal sensory ganglion cells in pigs killed during the incubation period was considered as positive evidence for viral spread via nerves.

Hemagglutinating encephalomyelitis virus (HEV; also designated vomiting and wasting disease virus) was inoculated oronasally in 14 colostrum-deprived pigs at the day of birth. Anorexia and vomition were seen after 4 days. Pigs were killed at different times after inoculation, and the results of the examination by immunofluorescent antibody technique revealed that the epithelial cells of nasal mucosa, tonsils, lungs, and small intestine served as sites of primary viral replication. After the local replication near the sites of entry, the virus spread via peripheral nervous system to the CNS. During the incubation period, viral antigens were detected in the trigeminal ganglion,the inferior vagal ganglion, the superior cervical ganglion, the intestinal nervous plexuses, the solar ganglion, and the dorsal root ganglia of the lower thoracic region. In the brain stem, the infection started in the trigeminal and vagal sensory nuclei and spread to other nuclei and to the rostral part of the brain stem. In later stages of the infection, viral spread into the cerebrum, cerebellum, and spinal cord was sometimes also observed. Viral replication in nervous plexuses of the stomach was not present during the incubation period, but was detected in all except 1 of the pigs that were ill when killed. The question whether the vomition is induced centrally by viral replication in the brain stem or is due to viral replication in peripheral nervous tissues remains unanswered.

Muscle weakness, neuropathy, and transient rises in hepatic enzyme activity have been reported with the use of the antiarrhythmic agent amiodarone. A 68 year old teetotaller with normal liver function was given amiodarone for resistant supraventricular arrhythmias. He presented 19 months later with vomiting, muscle weakness and wasting, sensory neuropathy, and hepatomegaly. Liver biopsy showed fibrosis and the presence of hyaline. The amiodarone was withdrawn. Three months later he developed ascites. Oesophageal varices were found and he later died. The liver showed micronodular cirrhosis. The large volume of distribution and long half life of amiodarone may explain the persistence of toxicity, which may have been aggravated by simultaneously administered doxepin in this case. Amiodarone should be withdrawn if abnormal liver function or neuropathy develops.
