The case records of and histopathologic findings in 57 dogs with nonangiogenic and nonlymphomatous splenic sarcomas were reviewed. Splenic neoplasms in these dogs included leiomyosarcoma, fibrosarcoma, undifferentiated sarcoma, liposarcoma, osteosarcoma, chondrosarcoma, myxosarcoma, rhabdomyosarcoma, and fibrous histiocytoma. The clinical signs associated with splenic sarcoma included anorexia or decreased appetite, abdominal distention, polydipsia, lethargy, vomiting, weight loss, and weakness. An abdominal mass was detected in 86% of the dogs by use of abdominal palpation (63%), and/or abdominal radiography (74%). The diagnosis was based on histopathologic findings in the spleen. Abdominal exploratory surgery was performed on 43 of the 57 dogs. Twenty-seven dogs were treated by splenectomy, and 16 were euthanatized at the time of surgery because of widespread metastatic lesions. Of the 14 dogs on which surgery was not performed, 11 were euthanatized on the basis of results of preoperative diagnostic tests, and the remaining 3 dogs had splenic neoplasms that were incidental findings at necropsy. Of the 27 surgically treated dogs, 5 died in the immediate postoperative period, 12 died or were euthanatized within 1 year after splenectomy, and only 5 dogs survived greater than or equal to 1 year. Three dogs were lost to follow-up evaluation, and 2 were still alive 6 and 7 months after surgery. The median survival time of the 22 dogs for which survival was known was 2.5 months. The median survival time for 11 dogs with no obvious metastasis at the time of splenectomy was 9 months.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a 9 year-old boy with MELAS. High dosed oral thiamine administration and high fat diet induced remarkable neurological and biochemical improvement. His mother had episodic headaches and hemiplegia, probably MELAS. He complained muscle weakness and repeated episodes of vomiting started from 2 years of age. High levels of serum lactate and pyruvate were recognized, but with no metabolic acidosis. He developed generalized muscle weakness, growth retardation, generalized convulsions and stroke-like episodes at 5 years old. Optic nerve atrophy and mental retardation gradually appeared. A muscle biopsy at 5 years old revealed numerous ragged-red fibers with excess accumulation of lipid droplets and glycogen particles. Scattered fibers had no cytochrome c oxidase (CCO) activity representing focal CCO deficiency. An electron microscopy showed markedly increased number of giant mitochondria filled with markedly proliferated complicated cristae. Pyruvate dehydrogenase complex level in the fibroblasts was within normal ranges. Serum carnitine level was normal. With oral administration of thiamine hydrochloride (1000 mg) and high fat diet (60-70%), muscle weakness improved, and lactate and pyruvate levels in the serum reduced to normal ranges, whereas the mental deterioration, muscle atrophy, pes cavus progressed very slowly. He died from cardiac and renal failures at 9 years old. Autopsied muscles showed a marked decrease in cytochrome c oxidase activity (biochemically 12.8% of the normal level), and almost all muscle fibers had no cytochrome c oxidase activity histochemically. The progression of the MELAS was probably in parallel with the decrease in CCO activity.

Acute toxicity studies of propiverine hydrochloride (P-4) were carried out in mice, rats and dogs of both sexes. 1. The LD50 values of P-4 were as follows: Mice; 410 (male) and 323 (female) mg/kg in oral route, 223 (male) and 283 (female) mg/kg in subcutaneous route and 36 (male and female) mg/kg in intravenous route, Rats; 1000 (male) and 1092 (female) mg/kg in oral route, 1632 (male) and 1411 (female) mg/kg in subcutaneous route, and 22 (male) and 25 (female) mg/kg in intravenous route. On the LD50 values, no sexual difference was apparent but the species difference between mice and rats observed to be present in oral and subcutaneous routes. The approximate lethal doses of P-4 in dogs were 987-1137 mg/kg for male and 865-894 mg/kg for female in oral route, and the values were almost same as those in rats of oral route. 2. Major toxic signs such as clonic convulsion, bradypnoea, dyspnoea, decreased spontaneous activity and hematuria were observed in mice and rats. Furthermore mydriasis in rats, and transitory salivation and/or vocalization in mice and rats were observed. In some rats, sedation, salivation, soil at hypogastrium, rale and emaciation were detected from the next day of oral administration. In dogs, toxic signs such as vomiting, tremor, tonic and/or clonic convulsion, mydriasis and gasping were observed. 3. Pathological changes observed in dead animals were congestion of lungs, liver and kidneys in all routes, congestion and hemorrhage in digestive tracts in oral route, inflammatory changes at the injection site in subcutaneous route. In addition, retention of hematuria in urinary bladder in rats of oral and subcutaneous routes, the hemorrhagic changes of heart, atonia of urinary bladder and retention of urine in dogs were observed. 4. The main cause of death seemed to be respiratory disturbance in all species and the weakness in a few rats of oral route.

Examined were 58 patients with primary postoperative peptic esophageal stricture (PPPES). The ulcer disease of pyloroduodenal location and impaired function of the esophagus were the leading causes of a stricture. The prognostic algorithm for the PPPES development, which considers the presence of hiatal hernia, severe disorders in gastric evacuation and vomiting, pronounced weakness of a patient, severe complications of the ulcer disease before the operation, has been developed. The prophylactic measures in given pathology are suggested.

Thirty-one patients with metastatic breast carcinoma refractory to standard hormonal and chemotherapy were treated with cisplatin 100 mg/m2 per course and etoposide 300 mg/m2 per course divided over 5 days. Courses were repeated at 3-6-week intervals, depending on the speed of recovery from myelosuppression. Of 29 evaluable patients, three had complete responses, eight had partial responses, eight had stable disease, and 10 had progressive disease. Nausea, emesis, anorexia, weakness, and easy fatigability were common but tolerable side effects. Myelosuppression was frequent and occasionally profound but there were no deaths from hemorrhage or infection. No significant renal toxicity was encountered. The combination of cisplatin and etoposide has sufficient antitumor activity with acceptable toxicity in heavily pretreated patients to justify its further study in breast cancer.

A clinical-epidemiological study of an accidental poisoning by Robinia pseudoacacia L. (lucust tree) in six school children has been made. The case had sucked and/or chewed the bark of this plant. The clinical symptoms were abdominal pain, thirst, nausea, vomiting, dry throat, muscle weakness, mydriasis, headache, dizziness and diarrhea. The treatment was activated charcoal in 5 cases and subsequent gastric lavage in 3 cases. The results was favorable. The poisoning took place in the school yard during the mid-morning recreation period. Only girls were affected (average age 6.5 +/- 2.1 years old). The attack rate was 31.6% for the school children who tasted the bark, and chewing it constituted the highest factor of risk (p = 0.03). Recommendations have been made to prevent childhood accidents.

Potassium is one of the most abundant ions in the human body and yet it is difficult to assess potassium balance. Potassium chloride is extensively used as a potassium supplement, both by physicians as a therapeutic modality and by the general public, mostly in the form of salt substitute. Therapeutically, both the oral and intravenous forms of potassium are utilised. Overdose of potassium is not as frequently encountered in clinical practice as hyperkalaemia (excess potassium in the body) due to acute or chronic renal disease. Potassium homeostasis is maintained very delicately and is governed by the daily consumption of potassium and the renal excretion mechanisms. Any change in these or related factors can present as hyperkalaemia. However, potassium overdoses leading to serious consequences do occur. Orally, the dose of potassium has to be large enough so that the normal excretory mechanisms for potassium are overcome and clinical toxicity occurs. It takes a much bigger dose of ingested potassium to produce toxicity in a person with normal renal function than in patients with compromised renal function. Potassium toxicity manifests in significant, characteristic, acute cardiovascular changes with ECG abnormalities. Besides cardiovascular effects, neuromuscular manifestations in the form of general muscular weakness and ascending paralysis occur. Gastrointestinal symptoms manifest as nausea, vomiting, paralytic ileus, and local mucosal necrosis which may lead to perforation. It is imperative when treating hyperkalaemia that the whole clinical picture is taken into account rather than the numerical potassium values. Only the extracellular potassium can be measured in the laboratory, yet 98% of the body potassium is intracellular and cannot be measured. In acute overdose situations due to ingestion of potassium salt, the general principles of treatment for overdoses should be followed. Calcium chloride infusion, dextrose and insulin in water, and correction of acidosis with sodium bicarbonate are helpful in controlling the acute, life-threatening cardiac arrhythmias. These modalities do not remove the excess potassium from the body. That is achieved either by utilising ion-exchange resins or by mechanically removing potassium via haemodialysis. To curtail inadvertent or accidental potassium overdoses, physicians should prescribe any potassium supplements very carefully to their patients and monitor the plasma potassium periodically.

The diagnosis of adrenal haemorrhage complicating heparin therapy is often delayed, despite computed tomography (CT). Moreover, its pathogenesis is not clear. Adrenal haemorrhages are often seen in cases where there is no unduly excessive anticoagulation, and can be accompanied by a paradoxical thrombosis of the central adrenal vein. Symptoms usually occur within the first 8 to 12 days after starting heparin. The difficulty in establishing the diagnosis stems from the fact that symptoms are rather nonspecific: abdominal pain and backache, nausea, vomiting, lethargy, weakness, hypotension, hyperpyrexia. To confirm the diagnosis, both hormonal proof of adrenal failure and anatomic evidence of haemorrhage must be found. Early CT scans may show the haemorrhage. Several possible causes have been put forward to account for these adrenal haemorrhages. The degree of anticoagulation did not seem to be a prerequisite, 30 to 50% of patients showing no evidence of other bleeding or coagulation tests outside the therapeutic range. Capillary fragility of old age might be a factor. Stress would seem to be an important factor predisposing to adrenal haemorrhage. Many authors consider the paradoxical central vein thrombosis as a result of the haemorrhage rather than its cause, whereas other conclude the opposite. Unfortunately, to date coagulation studies are often incomplete; platelet counts were missing in most reports published before 1985. Since that date, a heparin induced thrombosis-thrombocytopaenia syndrome (HITTS), in which thrombosis may occur in any vascular bed, has been recognized with increasing frequency. Nine cases of adrenal haemorrhage associated with HITTS have been reported. It seems highly likely that a proportion of cases of heparin-related adrenal destruction are due to HITTS.(ABSTRACT TRUNCATED AT 250 WORDS)

Lead poisoning resulting from exposure to lead in a domestic car battery workshop is reported in 10 children in 2 families. 2 girls, aged 2 10/12 and 1 8/12 years, respectively, from 1 of the families were hospitalized for investigation of nausea, vomiting, progressive muscular weakness and peripheral neuropathy. Serum lead levels were 52 and 49 mcg/dl, respectively. Subsequent screening of all members of this family, as well as those of the other family who lived in the same house, revealed abnormally elevated levels of serum lead in all the members of both families. The 2 girls were treated with chelating agents and improved clinically and their serum lead levels decreased to 29 and 34 mcg/dl, respectively. The domestic workshop was closed and the 2 families moved to another neighborhood. These cases illustrate the need to screen all family members and contacts of patients with lead poisoning, as well as the hazards of the uncontrolled use of lead in domestic workshops.

This is a report of the clinical analysis of 250 cases of dengue fever-like patients during the 1987-1988 epidemic in Southern Taiwan at Harn's clinic, Kaohsiung city. The results were: The peak age groups were between 20-40 years old. The ratio of male to female was 1:14. 98% patients presented with fever of mainly 3 to 6 days duration. 98% reported body pain, which included headache (82%), generalized soreness (65%), low back pain (50%). 95% patients had GI symptoms, such as anorexia (73%), nausea (60%), vomiting (45%). 97% patients complained of dizziness and weakness, and 22.4% patients had a bleeding tendency. The common bleeding sites were involving the subcutaneous (skin), gum, uterus, nasal cavity, GI tract, retina, and GU tract. The eruption rate was 78%. A majority of rashes appeared on the extremities, and then spread to the trunk. Less common symptoms were insomnia, chest tightness, urgency of urination, cough, running nose, palpitation, and shock. 45% patients were noted with hair loss. The hair loss was the latest presenting symptom, which tended to occur about two months after the recovery stage, and lasted for about one month. On physical examination, 62.6% patients had conjunctivitis, while only 1.3% had lymph node enlargement. Usually, the whole clinical course lasted for 7 to 14 days. Laboratory examination showed that leukopenia was noted from the second day and reached the lowest count on the fifth day, and recovered on 9th or 10th day. In 247 blood sera tested serologically for dengue fever, 84 were confirmed, while 157 were not confirmed yet due to patients' reluctance to accept a second blood drawing.(ABSTRACT TRUNCATED AT 250 WORDS)
