A 39-year-old man, known as a heavy drinker, presented with general malaise, abdominal pain, a history of icterus and progressive weight loss. He was found to have an acute hepatitis B infection and pancreatitis with pancreatic pseudocysts. A diagnosis of polyarteritis nodosa was made on clinical grounds, and confirmed pathologically. The patient was treated with high-dose corticosteroids, cyclophosphamide, antibiotics and drainage. However, the disease was progressive and the patient died. Pancreatitis in relation to polyarteritis nodosa, the association with hepatitis B infection, and new therapeutic possibilities are discussed.

Seven patients, 4 girls and 3 boys, aged 3 to 12 years /X = 7.14/ affected by haemorrhagic fever with renal syndrome /HFRS/., were hospitalized at the University Children's Hospital in Belgrade during the last two years /January 1988-January 1990/. The diagnosis was established on the basis of clinical features, epidemiological data and autopsy findings in one patient while in the others the diagnosis of HFRS was confirmed serologically by indirect immunoflorescence tests on Vero E 6 cells. A significant increase in antibody titre against Hantaan virus was found in all serologically tested patients. Three of them had also significant increase of antibody titre against Soeul and one against Puumale virus. In four patients the disease appeared as family outbreak at the end of January 1988 while the others were sporadical cases. All patients but one mentioned contact with rodents at home or in fields. The predominant slynical symptom were: sudden onset of febrile condition with headache, generalized malaise, myalgia, abdominal pain, vomiting, diarrhoea, oliguria and oedema. All patients had haematuria and only one had other severe haemorrhagic manifestations. Four patients were hypertensive. Two patients had renal insufficiency, but only one required haemodialysis. Five patients recovered after 2 to 8 weeks without sequellae, one patient was still /7 months after the beginning of the disease/ in mild renal insufficiency and one patient died. Autopsy findings showed tubular necrosis in the kidney, myocarditis, massive pneumonia with hydrothorax and jejunal haemorrhagia.

A 57-year-old man with malaise, ascites, and abdominal pain was found to have a peritoneum studied with numerous, small nodular tumor masses. Light microscopy revealed an anaplastic malignant tumor of uncertain differentiation. Mucin stains were negative. Electron microscopy revealed pleomorphic tumor cells with diffusely distributed cytoplasmic tonofilaments and well-developed true desmosomes. No long, thin, branching microvilli were present, yet tumor cells were strongly positive for both callus keratin (polyclonal) and monoclonal cytokeratin (AE1/3) in a diffuse cytoplasmic distribution (a pattern corresponding to the diffuse cytoplasmic tonofilaments). Tumor cells were negative for Leu-M1 and carcinoembryonic antigen. The findings were most consistent with malignant mesothelioma, and additional questioning, after tissue diagnosis, revealed a work history of asbestos exposure.

Pyridostigmine bromide, a reversible inhibitor of acetylcholinesterase (AChE), is effectively used as a pre-treatment to organophosphate intoxication. Previous studies have shown that an oral dose of 30 mg twice a day produces a sufficient inhibition of the enzyme activity (20-40%) without causing any significant adverse effect. During the Persian Gulf war pyridostigmine was taken for the first time under a chemical warfare threat. We searched for symptoms and complaints that may be related to the medication. Our survey included 213 soldiers who completed a questionnaire regarding possible symptoms and their severity. AChE inhibition level was compared between groups of soldiers with and without complaints. The most frequent symptoms were nonspecific and included dry mouth, general malaise, fatigue and weakness. Typical effects, such as nausea, abdominal pain, frequent urination and rhinorrhea, were infrequent. The severity of the symptoms was generally mild. The symptoms appeared around 1.6 h after taking the medication and recurred after each intake. No correlation was found between levels of cholinesterase and type or severity of complaints. Anxiety, which accompanies wartime, may have contributed to the appearance of significant symptoms. Further investigations concerning the effects of pyridostigmine ingestion under stressful conditions are warranted.

Six patients underwent image-guided percutaneous drainage of liver abscesses at the Instituto Nacional de la Nutricion (a tertiary care referral center in Mexico City) in a seven month period. These patients were closely followed in order to evaluate appropriate indications for percutaneous drainage as well as techniques, complications and clinical evolution. Our study group included five males and one female; their mean age was 44.4 years (28-63) and the mean hospitalization time 24.3 days (10-34). We found multiple liver abscesses in three patients, and solitary abscesses in three, two in the left lobe and one in the right lobe. Considering the largest diameter, mean abscess size was 13.7 cm. The most important clinical symptoms were: fever, abdominal pain and malaise, and the most significant laboratory abnormalities were anemia, hypoalbuminemia, leukocytosis and high alkaline phosphatase serum levels. Etiology could be determined in three cases, two were pyogenic abscesses and one amebic. Percutaneous drainage was successful in five out of our six patients (83.3%). Complications included one subcapsular hematoma, without hemodynamic consequences, and one patient with severe upper gastrointestinal tract hemorrhage who required surgery, but we could not entirely demonstrate that the bleeding episode was directly related to the percutaneous drainage.

A 15-year-old woman who was studied because an abdominal mass at the Instituto Nacional de la Nutricion Salvador Zubiran (INNSZ) is reported. The history revealed only malaise and mild abdominal pain. At physical exploration, an abdominal mass in the upper right quadrant was found. Liver function tests were normal. Abdominal ultrasound and computerized tomography revealed a large cystic mass of the right hepatic lobe. She underwent exploratory laparotomy. Intraoperative frozen sections of the biopsies demonstrated undifferentiated sarcoma of the liver, and an extended right trisegmentectomy was performed. Postoperative outcome was uneventful. Adjuvant treatment with doxorubicin and dacarbazine was given, and at six months of follow-up, the patient is alive without any evidence of recurrence. Clinical and histopathologic features of this rare malignant tumor are discussed, as well as the therapeutic choices.

The occurrence of cytomegalovirus infection after solid organ transplantation has been correlated with decrease patient and allograft survival. The disease has not been conquered for two majors reasons: the length of time to establish the diagnosis of CMV has been excessive, and suitable, nontoxic antiviral agents have not been available for use. The purpose of this study was to examine the current incidence and impact of tissue-invasive cytomegalovirus (TI-CMV) disease that developed in 93 patients who underwent solid organ transplantation at University of Minnesota Hospitals (3/1/87 and 6/30/89) and who were treated with antiviral agent ganciclovir ( [9-(1,3-dihydroxy-2-2-propoxymethyl)-guanine [DHPG]). During this same period of time 323 patients received kidney transplants and 71 received kidney-pancreas transplants. Three patient groups were defined: (1) no CMV; (2) CMV infection (cultural or serologic evidence of noninvasive CMV infection); and (3) evidence of TI-CMV disease based upon initial complaints of fever, malaise, dyspnea, or abdominal pain, leukopenia (WBC less than 3000/ml), and evidence of a positive CMV rapid antigen test, CMV culture, or the presence of characteristic CMV inclusion bodies upon examination of material obtained by means of bronchoscopy, upper-gastrointestinal endoscopy, colonoscopy, or liver or renal biopsy. Patients with solely fever, leukopenia, but without a rising CMV serum titer, or positive CMV urine or blood cultures were excluded from the study. A multivariate analysis revealed that rejection therapy, age greater than 50 years, and receiving an organ from a seropositive donor were all significant variables that predisposed to TI-CMV. Analysis of patient and kidney allograft survival indicated that asymptomatic CMV infection had little current impact upon patient or allograft survival, while patients who developed TI-CMV exhibited higher rates of allograft loss and mortality, despite DHPG therapy. Comparison with historical group of patients indicated that TI-CMV DHPG-treated patients exhibited a trend toward improved allograft survival that may be relevant because the historical group of patients included patients with mild CMV infection. DHPG therapy was well tolerated and produced minimal toxicity, and excellent 30-day cure rates (89.2%), although 21.2% of patients required retreatment subsequently. We are currently conducting a trial to compare the ability of DHPG administered plus an anti-CMV immune globulin preparation with acyclovir to prevent posttransplant TI-CMV disease.

Results of Yusho annual inspection were reviewed from the view point of correlation of PCBs, PCQs and PCDFs concentration in blood or subcutaneous adipose tissue and clinical findings. To make discussion quantitative, fifteen terms of clinical findings on Yusho disease were quantified on the severity by evaluating (+) as 2 points, (+-) as 1 point and (-) as 0 point. First, the temporal variations of the severity of clinical findings on 5 Yusho patients were figured. Additionally, the temporal variations of blood triglyceride and PCBs concentration, and GOT were also surveyed. The adopted terms of clinical findings were general malaise, cough, sputum, headache, abdominal pain, peripheral neuropathy, soreness of joints, deformity of nails, comedo formation, acne-like eruption, secondary infection, scar formation, disorder of Meibomian glands, edema of eye lids and increased discharge from the eyes. During the investigated period from 1972 to 1988 the total score of clinical findings clearly decreased on two patients who had high score, tended to decrease on two other patients, and was not clear on another patient. Secondly, the correlation coefficients were calculated between each of PCDFs, PCBs or PCQs concentration in subcutaneous adipose tissue or blood and the total score at the year in which the adipose tissue and blood were taken. For the female patients the correlation coefficient of PCDFs concentration in subcutaneous adipose tissue and total score of clinical findings was the highest of all (r = 0.9885). However, for the male patients it was not available because the number of the subjects was only two. Thus far it has been reported that the powers of PCBs gas chromatogram pattern and PCQs concentration as criteria for Yusho diagnosis are low as for the subjects who belonged to the border area between Yusho patients and normal persons. This survey suggests that PCDFs concentration in subcutaneous adipose tissue can be a potent criterion that has a high correlation with the clinical findings of Yusho.

The clinical data of 97 patients with Yersinia enterocolitica infection during 1989 were evaluated. The diagnosis was made by positive culture, serology and/or detection of Yersinia antigens in biopsies. The enteric form (enteritis, abdominal syndrome, pseudo-appendicitis, ileitis and colitis) occurred in 66% of all patients, 10 (10%) had an extramesenteric form, 22 had arthritis and 6 had erythema nodosum. The mean age was 33.6 (SD 19.4) years. Abdominal pain was the syndrome most frequently observed (in 55%), followed by diarrhoea in 44% and malaise in 41%. The duration of the disease was shorter than four weeks in 37% and longer than eight weeks in 34%. Serotype 03 was most frequently isolated. The agglutination reaction was positive in 25%, false-positive in 7% and false-negative in 68%; 91% had specific IgA and IgG antibodies against two or more virulence proteins (Yops).

The epidemiology, pathogenesis, clinical manifestations, and treatment of Mycobacterium avium complex (MAC) infection are reviewed. MAC infection is one of the most common infections in AIDS patients. Its pathogenesis is poorly understood, but it is believed to develop by gastrointestinal colonization followed by systemic invasion. The relatively poor response to treatment may be partly accounted for by the tremendous mycobacterial load present by the time patients develop systemic symptoms. Clinically, MAC infection is difficult to differentiate from the signs and symptoms of AIDS or from other opportunistic infections. Signs and symptoms include fever, malaise, anorexia, night sweats, and weight loss; diarrhea and abdominal pain may also be present. There is no established therapy for MAC infection, although combinations of three to five antimicrobial agents are typically used. There has been consistently poor correlation between in vitro results and in vivo outcomes in the treatment of MAC infection. Currently, the role of treatment is mainly to suppress the progression of infection and to relieve symptoms. Recent in vitro studies and animal studies have revealed possible alternative agents and combinations of agents (e.g., macrolide antibiotics, quinolones, amikacin, cytokines) that may influence therapy of MAC infection. No known therapy for MAC has been shown to prolong survival in AIDS patients, possibly because of the high organism load that exists once patients become symptomatic. Research is needed to find improved methods for earlier detection of MAC infection, determine optimal dosage regimens of current antimycobacterial agents, develop better antimycobacterial drug-delivery systems (e.g., liposomes), and discover new antimicrobials with better activity against MAC and methods of immune modulation that will overcome immune system defects.
