In a multicentre, cooperative study into the treatment of extensive psoriasis with a new aromatic retinoid (Ro 10--9359) trichogram, liver function tests and the light erythema threshold were investigated. In some of the patients hair loss occurred, usually in the fifth to eighth week after a total dose of 1.9 g retinoid. In all cases this improved an average of six weeks after dose reduction or cessation of treatment. The trichogram in 27 patients showed a diffuse toxic hair loss. In 70% the effluvium was telogenic, in 22% telogen-dystrophic. GPT, GOT, alkaline phosphatase and prothrombin index showed no significant alterations during retinoid treatment. However, in individual cases there was a rise in GOT and GPT up to 80 U/l. Furthermore there was a statistical tendency in rising bilirubin levels. Finally there was no evidence for an increase in light sensitivity after three weeks of retinoid treatment. Measurement of the erythema threshold showed rather more a reduction in light sensitivity under treatment.

Ten episodes of massive transaminase increase with hepatic necrosis were observed in 7 patients after infusion of megluminioglycamide (Biligram). The patients were 3 men and 4 women aged 49 to 65 years with biliary tract disease (n = 1), recurrent pancreatitis (n = 1), hyperlipidaemia and minimal toxic liver damage (n = 1), pyelonephritis (n = 1), , arteriitis (n = 1), and pseudo-LE (n = 1). In 6 patients there was an increase of the alkaline phosphatase without icterus before the investigation and a slight increase of transaminases in 3 patients. After infusion of 100 ml of Biligram in 5 patients and of 200 ml in 2 patients there was an abrupt increase of GPT (98-2202 U/l) with a lesser increase of GOT. The alkaline phosphatase activity remained unchanged. Three patients showed symptoms such as upper abdominal pain, fever erythema, or conjunctivitis. Histologically all patients showed centrolobular necroses. Transaminases should be checked 2 days after intravenous cholangiograms. In patients with a definite increase reexposure should be avoided.

A 42-year-old woman was admitted because of cough, sputum, and fever. A chest roentgenogram revealed a nodular density in the left upper lung field with satellite lesions compatible with tuberculoma. Mycobacterium tuberculosis was detected from sputum. Five weeks after starting the treatment with 0.4 g/day of isoniazid, 0.45 g/day of rifampicin, and 0.75 g/day of streptomycin, she showed itching erythema in the trunk. The white blood cell count was 4,500/mm3 with 14% eosinophils, and serum transaminases were slightly increased (GOT 101 U/L, GPT 74 U/L). Although isoniazid and rifampicin were stopped, the erythema with exfoliation spread to her extremities, suggesting exfoliative dermatitis. The white blood cell count reached 15,990/mm3 with 68% eosinophils (10,810/mm3). Stimulation indices measured with the lymphocyte stimulation test (LST) were 109% with rifampicin, 140% with isoniazid, and 275% with streptomycin, suggesting streptomycin-induced allergy. After cessation of streptomycin, the symptoms gradually improved. After the reaction had subsided, the treatment with isoniazid, rifampicin, and ethambutol was resumed, but she showed no further adverse reactions. LST seems to be very useful to identify the drug or drugs responsible for the reactions occurred during the treatment by antituberculosis drugs.

A 51-year-old man had for 5 years been known to have erythropoietic protoporphyria. GPT levels were raised up to 40 U/l, gamma-GT up to 120 U/l. After lengthy exposure to sun radiation an erythema with blisters, abdominal discomfort and jaundice developed (total bilirubin 7.3 mg/dl) and biliary liver cirrhosis with portal hypertension and splenomegaly were diagnosed. Because the acute hepatobiliary complications were not improved by conservative treatment (daily 750 mg ursodeoxycholic acid and 12 g colestyramine), an orthotopic liver transplantation was performed without complication. The excised liver showed small nodular parenchymal transformation and contained reddish brown protoporphyrin pigment in the hepatocellular cytoplasm, the Kupffer cells, the canaliculi and in some biliary ducts. Bilirubin and transaminase levels in blood became normal after the transplantation, as did the urinary excretion of coproporphyrin. However, isomer I was still dominant. The protoporphyrin level in erythrocytes and plasma remained elevated. After a symptom-free interval of one year biochemical and histological tests demonstrated protoporphyrin-induced damage in the transplanted liver.

A newly recognized disease in dogs, ulcerative dermatosis associated with diabetes mellitus (diabetic dermatopathy), was diagnosed in 2 dogs with pancreatic endocrine tumors that had immunohistologic evidence of glucagon production. Dogs developed diabetes mellitus in the later stages of the illness, months after the skin disease was first observed. Liver disease was identified and characterized by high serum alkaline phosphatase and alanine transaminase activities. Clinically, erythema and crusting involved the footpads, the face, perioral and genital skin, and ventrum. Histologically, skin lesions were intercellular and intracellular edema and necrosis of the upper half of the epidermis and diffuse parakeratosis. Clinically and histologically, skin lesions closely resembled necrolytic migratory erythema of people, a skin disease that usually is associated with a glucagon-secreting pancreatic endocrine tumor and diabetes mellitus (glucagonoma syndrome): The morphologically descriptive term, superficial necrolytic dermatitis, was preferred over the previously proposed names hepatocutaneous syndrome and diabetic dermatopathy, which each connote only a single feature of the disease.

A randomized double-blind study was performed to compare the side effects of long-term chemoprophylaxis of malaria with Fansidar (1 tablet a week) with those of a 300-mg weekly chloroquine regimen. This study was designed as a field trial with Austrian industrial workers in Nigeria and included 173 volunteers, 86 taking Fansidar and 87 taking chloroquine for 6 to 22 months. Only a few complaints were reported during that time, gastrointestinal disorders predominating in the Fansidar group and insomnia in the chloroquine group (3 cases each). The other complaints in both groups included one case each of skin rash and of visual disturbance, as well as one case of facial erythema after alcohol consumption in the Fansidar group and one of hair loss in the chloroquine group. Laboratory checks were performed at 3-monthly intervals, and included white and red cell counts, platelet counts and determination of GOT, GPT and alkaline phosphatase. There were no signs of drug-associated liver damage. In the Fansidar group there occurred a slight and transient decrease in the red cell count and in the chloroquine group a slight and transient decrease in the white cell count. Although statistically significant, these changes were without clinical significance. It is noteworthy that there were no cases of leucopenia in the Fansidar group. With the exception of one volunteer, who had discontinued his prophylactic drug regimen, malaria did not occur. Antibodies against blood stage parasites as determined by the indirect immunofluorescence test (IIFT), however, could be found at different stages of the study, which indicates that these two antimalarials are not causal prophylactic agents.

The acute toxicity of hexazinone, a herbicide intended for general noncropland areas and selected crop uses (alfalfa and sugarcane), has been evaluated to establish proper handling guidelines and to measure its potential impact on the environment. The material is slightly to moderately toxic when given as a single oral dose; its LD50 in male rats is 1690 mg/kg, in male guinea pigs 860 mg/kg, and in male dogs greater than 3400 mg/kg although in the dog emesis prevented accurate quantitation. When the material is administered intraperitoneally, the LD50 in rats is 530 mg/kg. Repeated doses (five oral doses per week for 2 weeks) of 300 mg/kg to rats produced slight weight loss in one of two replicate experiments. In both studies, no gross or histologic alterations were apparent. Hexazinone is a moderate to severe eye irritant in the rabbit and produced only mild erythema in rabbit skin at 5278 mg/kg, a dose which did not produce lethality or other clinical signs. Subchronic dermal exposures (10 consecutive doses) to rabbits produced increases in serum alkaline phosphatase and glutamic-pyruvic transaminase at the highest levels tested (680 and 770 mg/kg in two separate experiments) with no effects seen at 150 mg/kg. There were no alterations in livers from treated rabbits examined by light microscopy. No dermal sensitization was produced when concentrations of up to 50% were tested in guinea pigs. One-hour inhalation exposure of up to 7.48 mg/liter did not produce mortality in rats.(ABSTRACT TRUNCATED AT 250 WORDS)

A 54-yr-old man was admitted to Hokkaido University Hospital, complaining of fever, multiple arthralgia, edematous erythema and face and muscular weakness of extremities during the last 2 months. He was diagnosed as dermatomyositis by acceleration of ESR, elevation of GOT, GPT, CPK, aldolase, moderate increases of collagen fibers in biopsy specimen of skin and his clinical signs. Although stools were positive for occult blood, the routine radiographic examination failed to detect the bleeding site in the upper GI. tract. However, in the double contrast picture of the stomach, a very fine abnormal linear shadow was observed at the upper corpus of the lesser curvature. This linear shadow was a margin of the tumor, retrospectively. About 4 months later, abnormal pain occurred and a mass was palpable in the left lumbar region, suggesting a pancreatic tumor. He was operated on excising the tumor, but was performed only exploratory laparotomy because of the presence of intra-abdominal metastases. Death occurred 40 days after the operation and necropsy was done. The gross anatomical findings of the abdomen showed a stomach tumor as large as an infant's head and its metastases to pancreas, lymph nodes, and greater and lesser omentum. Esophageal mucosa including esophagocardiac junction was intact. Histological examination of the intragastric tumor revealed a typical squamous cell carcinoma with keratinization. According to the absence of the components of adenocarcinoma and squamous metaplastic gastric mucosa of non-cancerous areas in the stomach, it seemed likely to be a heterotopic squamous cell carcinoma. It was unknown about the precedence between the stomach cancer and dermatomyositis. There have been 11 cases of primary pure squamous cell carcinoma in the world literature since 1968, but this is the first case report of coexistence of these two diseases.

A comparative clinical trial of tropisetron capsule was conducted in three dose groups to investigate its optimal dose on nausea and vomiting induced by anti-cancer drugs, including cisplatin. The doses were randomized by the central registration office. In the assessment of clinical efficacy, cases rated as "effective" or better accounted for 61.5% of the 2.5 mg group (16/26), 80.8% of the 5.0mg group (21/26) and 80.0% of the 10mg group (24/30), respectively; the ratings for the 5mg and 10mg groups were almost equivalent, which was higher than that for the 2.5mg group. Adverse events observed were fever, diarrhea, drowsiness, headache and/or facial erythema in 4 out of 97 cases. Abnormal laboratory findings noted were 6 cases of increased GOT, GPT, LDH, total bilirubin and/or creatinine, but none of these was serious or clinically problematic in particular. On the basis of the above results, the optimal dose of Tropisetron (capsule) is considered to be 5mg once daily.

Liver cirrhosis (LC) in habitual drinkers is divided into three categories: (1) alcoholic LC, (2) LC due to hepatitis C virus and alcohol, and (3) LC due to hepatitis C virus. In Japan, the frequency of LC related to hepatitis B virus in habitual drinkers is comparatively low. Although making a distinct differentiation is very difficult, it is possible to point out some characteristics which ars due to either alcohol or hepatitis C virus: (1) multiple spider angioma, acne rosacea, and palmar erythema are more frequently found in categories 1 and 2 than in 3, (2) levels of AST/ALT, gamma-GTP, TG, ALP, lactate, and UA are higher in category 1 than in 3, (3) enlargement of both lobes is observed in category 1, and (4) abnormality due to alcohol improves relatively soon after abstinence of alcohol.
