This report concerns five cases of human infection resulting in lesions morphologically similar to human orf. Parapoxvirus infection in reindeer was the probable source of infection in four cases. The fifth case involved musk ox. Two of the cases involving reindeer are particularly interesting as transmission of infection occurred indirectly. Viral particles were not seen by electron microscopy of human tissues, due probably to the late stage of the illness at the time of examination. However, electron microscopy of negatively stained suspensions prepared from biopsy material collected from reindeer calves at the outbreak of the illness and of post-mortem material from the musk ox revealed characteristic parapoxvirus particles. In one patient the infection was accompanied by fever, lymphadenopathy and nausea, which cleared following a few days of treatment with doxycycline chloride. 4 cases were curetted after 4, 6, 12 and 20 weeks and healed withour scarring whereas the fifth patient was by request left alone. This resulted in localized dark pigmentation following completion of the healing process after 26 weeks.

Sixteen patients with cutaneous sarcoidosis, 15 of whom also had involvement of other organs, were treated with methotrexate (MTX) orally once a week in an open study. The treatment period was from 1 to 72 months (mean 23 months). In 12 patients the skin lesions cleared, and in 3 of 4 patients who had sarcoid uveitis this cleared as well. The chest X-ray of 6 patients showed no corresponding improvement in pulmonary changes or in hilar adenopathy. Ten patients suffered side effects, usually nausea on the day MTX was taken. Two had transiently increased transaminase levels. Treatment was discontinued in 2 patients due to nausea. It is concluded that MTX is a useful alternative to systemically administered glucocorticoids in the treatment of disfiguring cutaneous sarcoidosis and sarcoid uveitis. The effect of MTX on hilar adenopathy and pulmonary sarcoidosis is uncertain.

A 19-year-old man presented with dyspnea, cough and chest pains; he also complained of nausea, anorexia and postprandial vomiting and reported a 10-kg weight loss. Generalized lymphadenopathy and some rales over both lung bases were noted and a chest radiograph showed bilateral nodular lesions. Persistent leukocytosis, thrombocytosis, proteinuria and anergy to a series of natural antigens were found. The diagnosis of lymphoid interstitial pneumonia was made from material obtained at open lung biopsy. Rapid but incomplete clearing of the lung lesions resulted from steroid therapy; the other abnormalities were corrected gradually, except for the proteinuria, which persisted. The clinical improvement and the ability to work and play have been maintained for the past 20 months.

Bajiaolian (Dysosma pleianthum), one species in the Mayapple family, has been widely used as a general remedy and for the treatment of snake bite, weakness, condyloma accuminata, lymphadenopathy and tumours in China for thousands of years. However, the textbooks of traditional Chinese medicine mention little about the toxicity of Bajiaolian. Within 1 year, the authors saw five people who manifested nausea, vomiting, diarrhoea, abdominal pain, thrombocytopenia, leucopenia, abnormal liver function tests, sensory ataxia, altered consciousness and persistant peripheral tingling or numbness after drinking infusions made with Bajiaolian. The herb was recommended by either traditional Chinese medical doctors or herbal pharmacies for postpartum recovery and treatment of a neck mass, hepatoma, lumbago and dysmenorrhoea. Podophyllotoxin is one of the main ingredients of the Bajiaolian root. The clinical manifestations observed in our patients were consistent with podophyllum intoxication. Podophyllotoxin intoxication usually results from the accidental ingestion or topical application of podophyllum resin. However, these cases of Bajiaolian intoxication were iatrogenic and results from 'therapeutic doses' of Bajiaolian cited in the textbooks of traditional Chinese medicine.

This is the first report from Ethiopia of a case of cryptococcal meningitis in a patient with AIDS. A 20-year-old woman was admitted to Tikur Anbessa Hospital in January 1990 with complaints of generalized pruritic skin lesions of six months, and headache, fever, and poor appetite of three months duration. The headache and low-grade intermittent fever were accompanied by nausea, vomiting, anorexia, and progressive weight loss, without diarrhea. She had had multiple sex partners. Upon admission, after being bedridden for two weeks, she appeared acutely ill and restless. Her temperature was 39.5 degrees Celsius, and she had oral thrush. There was no lymphadenopathy. Widespread, irregular erythematous and whitish macular patches (3 x 5 to 8 x 10 sq. cm in size) with peripheral scaling and tiny vesicles were found on the skin, pubic and perineal regions. She had neck stiffness, but was conscious and well-oriented. Hemoglobin (Hb) was 10.5 g%; the white cell count (WBC) was 3400/cu. mm; the erythrocyte sedimentation rate (ESR) was 92 mm/hr; the platelet count was 175,000/mm; and blood films were negative for hemoparasites. Urinalysis showed 3+ albumin and many pus cells and red cells/HPF. Urine culture was negative, and the VDRL test was nonreactive. Lumbar puncture, which was performed upon arrival, showed clear cerebrospinal fluid (CSF), with normal protein and glucose levels and no cells. CSF culture showed yeast cells, and an India ink preparation was positive for Cryptococcus neoformans. Blood taken for bacterial culture grew yeast cells. Renal and liver function tests, and chest x-rays were normal. A potassium hydroxide (KOH) preparation from a skin snip showed rounded yeast cells. ELISA and Western blot tests were both positive. The patient was given supportive treatment and amphotericin B (0.6 mg/kg daily). Although the fever decreased, the patient's general condition did not improve. She complained of headache, photophobia, nausea, and vomiting. Lumbar puncture was repeated eight days after the start of treatment; CSF culture and India ink preparations were negative. Urea nitrogen (BUN) repeated two weeks later was normal. Four weeks after admission, the patient suddenly vomited massive amounts of fresh blood and died before transfusion could be given. A discussion follows regarding the clinical manifestations, diagnosis, and treatment of this disease, particularly in AIDS patients, with a review of the literature.

A 39-year-old woman was evaluated for possible liver transplantation due to rapidly developing hepatic failure 4 weeks after initiation of oral minocycline 100 mg twice a day for the treatment of acne. The patient developed a maculopapular rash, malaise, fever, nausea, and vomiting 2 weeks prior to admission to the hospital. On admission, her symptoms rapidly progressed to liver failure characterized by rapidly rising liver enzyme levels, worsening encephalopathy, and coagulopathy. Viral hepatitis serologies and blood cultures were all negative. After intensive supportive care for 2 weeks, the patient's condition gradually improved and she was discharged with mildly elevated liver enzyme levels and pruritus, without need of liver transplantation. Minocycline-induced hepatic injury is an idiosyncratic reaction with a sensitization period that appears to be 3-4 weeks in duration. The characteristic features include rash, fever, lymphadenopathy, and eosinophilia, as well as severe alterations in liver function. The high liver enzyme levels and the significant prolongation of the prothrombin time suggest massive hepatocellular damage. In light of the profound liver damage that occurs with this adverse reaction, care should be taken in administering minocycline to patients who have concomitant liver disease. It is recommended that patients should be instructed as to the possible signs and symptoms of toxicity and be monitored for evidence of idiosyncratic reaction or liver failure.

An outbreak of severe haemorrhagic illness began in the municipality of Guanarito, Portuguesa State, Venezuela, in September, 1989. Subsequent detailed study of 15 cases confirmed the presence of a new viral disease, designated Venezuelan haemorrhagic fever. Characteristic features are fever, toxicity, headache, arthralgia, diarrhoea, conjunctivitis, pharyngitis, leucopenia, thrombocytopenia, and haemorrhagic manifestations. Other features include facial oedema, cervical lymphadenopathy, nausea/vomiting, cough, chest or abdominal pain, and convulsions. The patients ranged in age from 6 to 54 years; all were residents of rural areas in central Venezuela, and 9 died. Infection with Guanarito virus, a newly recognised arenavirus, was shown by direct culture or by serological confirmation in all cases. Epidemiological studies suggest that the disease is endemic in some rural areas of central Venezuela and that it is rodent-borne. Venezuelan haemorrhagic fever has many similarities to Lassa fever and to the arenavirus haemorrhagic fevers that occur in Argentina and Bolivia.

Methylglyoxal bis-guanylhydrazone (MGBG), a potent inhibitor of polyamine synthesis, has demonstrated single agent activity against a number of tumor types including malignant lymphomas and head and neck, esophageal and non-small cell lung cancers. The growth of small cell lung cancer (SCLC) cell lines can be arrested by polyamine inhibition. Therefore a phase II trial was conducted in twenty-four patients with refractory SCLC. MGBG was administered by intravenous infusion at a dose of 500 mg/m2 per week for four cycles and then every two weeks thereafter. The dose was escalated by 100 mg/m2 every two weeks in the absence of toxicity greater than or equal to grade 2. One patient achieved a partial response of objectively measurable lung disease and supraclavicular adenopathy. Three patients had stable disease. Dose limiting toxicity consisted primarily of mild to moderate nausea, vomiting, stomatitis and/or diarrhea. Myelosuppression was uncommon and rarely dose limiting. We conclude that MGBG in the dose and schedule used does not have significant activity as a single agent in previously treated small cell lung cancer.

Carbetimer (carboxyimamidate) was administered at a dose of 6,500 mg/m2/day intravenously for 5 consecutive days to 14 patients with measurable metastatic or recurrent colorectal cancer in a single institution phase II study of the Northern California Oncology Group. A total of 38 cycles of therapy were administered; nine patients completed at least three cycles of treatment. No partial or complete responses were observed. One patient did have a greater than 50% response in the liver while developing new retroperitoneal lymphadenopathy and is considered a nonresponder. Carbetimer was well tolerated with elevations of calcium from 10.2 to 12.5 mg/dl in nine patients, prolongation of prothrombin time and partial thromboplastin time in 14 patients, proteinuria in 10 patients, dizziness in six patients, nausea in two patients, and venous pain during infusion in three patients. Myelosuppression was not observed. Carbetimer at this dose and schedule is inactive in the treatment of colorectal cancer.

A 17-year-old male was admitted to our hospital complaining of fever, headache and nausea. On physical examinations cervical and inguinal lymphadenopathy and hepatosplenomegaly were noted. Neurological examination revealed meningeal signs. Blood examination showed slightly increased lymphocytes and atypical lymphocytes (1-4%), increased ESR, CRP (2+), slightly elevated EBV VCA IgG (X20), and normal EBV VCA IgM (less than X 10). Initial pressure of CSF was 195mmH2O, cells 46/3mm3, protein 50mg/dl. Slowing of back ground activity of EEG such as theta and delta wave was noted. CT scan revealed normal. During the course EBV VCA IgG elevated to X160, EBV VCA IgM elevated to X20. Slight respiratory disturbance, photophobia, and dysosmia were noted. One month later, clinical symptoms and laboratory data improved, the patient was discharged. Forty days after the discharge, headache was excerbated and increased CSF protein (100mg/dl) and pleocytosis (33/3mm3) were noted. The patient was readmitted to the hospital. After 2 weeks in the hospital, symptoms were diminished and laboratory findings revealed normal. During 2 years before the third admission he was asymptomatic and could enjoy the college life. At age 19, he was admitted to our hospital complaining of fever, headache and nausea. Neurologically slight meningeal irritation was noted. Blood examination revealed 1% atypical lymphocytes. EBV VCA IgG was elevated (X320) and EBNA was X80. CSF protein was slightly increased (52mg/dl). During the clinical course CSF protein was elevated to 105mg/dl and cell count to 502/3mm3 (N: L = 27: 409, with 66 atypical lymphocytes). Persistent hiccup was noted. After 50 days CSF findings were improved and he was discharged.(ABSTRACT TRUNCATED AT 250 WORDS)
