Five uraemic patients who developed progressive cardiac failure with clinical evidence of congestive cardiomyopathy at the start or during haemodialysis treatment were studied. The diagnosis of cardiomyopathy, for which there was no apparent cause, was confirmed by angiocardiographic and haemodynamic studies. These showed a significant increase in left ventricular end-diastolic volume over normal values obtained in 12 patients without uraemia. The mean velocity of myocardial fibre shortening was significantly decreased, as was the index of normalised rigidity. Three of the five patients presented the complete picture of the disease. The other two also had considerable ventricular dilatation and a decreased index of normalised rigidity but normal ejection fraction and only moderately decreased myocardial contractility indices. This suggests that there may be primary involvement of normalised heart muscle rigidity followed by secondary changes in myocardial contractility in uraemic patients with congestive cardiomyopathy.

The patient was a 60-year-old man who had complained of left cervical swelling from the end of June, 1984. He was diagnosed as having Hodgkin's disease (mixed-cell type) by lymph node biopsy, and was admitted to our hospital for thorough examination and treatment on July 23rd. Diagnosis of stage IA Hodgkin's disease involving only the left cervical lymph node was made. On admission, laboratory data revealed that the LDH activity in his serum and erythrocytes consisted of only type 1 (LDH-H4), hence LDH-M subunit deficiency (homogeneous type) was diagnosed. However, the muscle rigidity, myoglobinuria, and skin lesions that are usually seen in this abnormality were not observed. After two course of C-MOPP therapy, beginning on August 1st. complete remission was obtained. He was subsequently given a total of 6 courses of C-MOPP therapy and 40 Gy of irradiation on an outpatient basis. He eventually died of heart failure on November 3rd, 1986. Only five families with LDH-M subunit deficiency have been reported to date in Japan. This is the first report in Japan of the condition being complicated by Hodgkin's disease.

We present an autopsied case of striatonigral degeneration (SND) combined with olivopontocerebellar atrophy (OPCA) with subcortical dementia and hallucinatory state. A Japanese woman without a remarkable family history showed hand tremor at the age of 35 years, followed by bradykinesia, muscle rigidity, orthostatic hypotension, neurogenic bladder and pyramidal signs. No obvious cerebellar symptoms were found. Various antiparkinsonian drugs were administered, but were not markedly effective for the parkinsonism. She developed a mild dementia characterized by mild memory disturbance with preservation of orientation, slowing of thought processes, emotional lability toward sadness, impaired ability to manipulate acquired knowledge and poor calculating, and by the absence of aphasia, apraxia and agnosia. The features in this patient were consistent with those seen in subcortical dementia. She also had auditory hallucinations. MRI revealed hypointense T2 signals in the putamina and substantia nigra. T1-weighted MRI demonstrated atrophy of both the pons and cerebellum in addition to atrophy of the putamina and substantia nigra. EEG showed slowing of background activity. She died of cardiac failure at the age of 47. Autopsy disclosed brain stem tegmental atrophy, SND, OPCA and many glial cytoplasmic inclusions in the central nervous system, but well-preserved cerebrum. We discuss the relationship between the psychiatric symptoms and pathologic findings of brain stem tegmentum.

The most venomous scorpion species are Buthotus tamulus of India, the Leiurus quinquestriatus and Androctonus crassicauda of North Africa and the Middle East, the Tityus serrulatus of Brazil, and the Centruroides suffussus of Mexico. The severity of scorpion envenomation varies with the scorpion's species, age, and size, and is much greater in children. Systemic intoxication reflects the overstimulation of the CNS, the sympathetic and parasympathetic nervous system. Severity ranges from local pain and paresthesia to fatal cardiotoxicity and encephalopathy. Symptoms include: agitation, tachycardia, vomiting, abdominal pain, salivation, diaphoresis, dehydration, muscle rigidity and twitching, tremor, seizures, coma, pupillary changes, hyperthermia, tachyarrythmias and occasionally bradyarrhythmias, hypertension, and less often hypotension, cardiac failure, and priapism in males. Laboratory abnormalities include: hyperglycemia, leucocytosis, transient elevation of cardiac and pancreatic enzymes, ischemic changes in the ECG, and evidence of cardiac dysfunction on echocardiography. The principles of management are: observation, cardiac monitoring, supportive treatment with intravenous fluids and electrolytes, and a meticulous use of cardiovascular agents: vasodilators, adrenergic antagonists, or calcium channel blockers in the hypertensive phase; and inotropic agents in the event of hypotension. Antiarrhythmics such as lidocaine, may be required. There is increasing evidence for the efficacy of specific antivenom. The advance in supportive care and antivenom efficacy has markedly improved the outcome of patients with scorpion envenomation.

A case of fatal suicidal bentazon poisoning is presented along with a description of the different analytical methods involved. A 56-year-old farmer was examined by the family doctor 1 h after voluntarily ingesting 500 mL of FIGHTER (bentazon, 480 g/L water). He presented a Glasgow score of 15, polypnea, diarrhea, and vomiting. During transport by ambulance to the hospital, he tossed, sweated, and suddenly presented breathing difficulty followed by heart failure. Tracheal intubation was impossible (H1.5) despite use of different diameter cannulas because of extreme general muscle rigidity. All attempts at resuscitation failed, and the patient died within 2 h postingestion. Blood and urine samples were taken just before death. General basic and neutral drug screening by high-performance liquid chromatography-diode-array detection and gas chromatography-nitrogen-phosphorus detection showed no strychnine or other drugs or toxics except for citalopram (< 0.1 mg/L) and bentazon, but this weak acidic molecule (pKa3.3) was badly extracted in alkaline conditions. Plasma and urine levels, measured after acidic extraction, protein precipitation, or simple dilution, were 1500 and 1000 mg/L, respectively. Bentazon (M.W. 240) was confirmed by its basic mass spectrum (ESI-, m/z 239, 197, 175, 132) or by that of methylated derivative (El+, m/z 254, 212, 175). An hydroxylated metabolite (ESI-, m/z 255, 213, 191, 148; El+, m/z 284, 242, 163) and the N1-glucuronide conjugate of bentazon (ESI-, m/z 415, 239) were also detected in urine. (Quantitation ions are underlined.) This first case of bentazon poisoning with available analytical data revealed the high toxicity of this compound after large dose ingestion with early and heavy symptoms such as muscle rigidity probably related to muscular toxicity. Comparison with another nonfatal case and with toxicological data on animals is discussed.
