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.

Modified Ziehl Neelson staining technique was used to identify Cryptosporidium species oocysts in stool specimens. Faecal samples from 166 children with diarrhoea and from a control of 95 children, were submitted for examination. 13 children from among those with diarrhoea and none from the control group were found to have Cryptosporidium species oocysts. The majority of these 13 positive children presented with abdominal pain, nausea, low grade fever and anorexia.

Three cases of pancreatic tuberculosis are described. The first patient presented with abdominal pain, weight loss, anorexia, vomiting, hepatomegaly, and mass in the head of the pancreas, on computerized tomographic (CT) scan. The second patient presented with low grade fever, anorexia, and weight loss, and was investigated for gallbladder disease. The third patient presented with obstructive jaundice and mass lesion in the head of the pancreas. Two patients underwent laparotomy for suspected pancreatic tumors. The findings of pancreatic disease was incidental during laparotomy in the second patient. The histopathology revealed caseating granuloma in all of them. The first patient responded well to treatment, and the second patient stopped treatment after 2 months and is well. The third patient is being followed. If malignancy can be ruled out, tuberculosis should be considered in relevant geographic areas, and a tissue diagnosis should be made.

During the period 1978 to 1988, 4619 upper gastrointestinal fibreoptic panendoscopies were carried out. There were 106 (2.2%) histologically confirmed cases of carcinoma of the stomach. The annual incidence was 9.6. The peak incidence was in the fifth decade. The mean age of these patients was 49.4 years and the male: female ratio was 3.6:1. The most frequent symptoms were weight loss (81%) and anorexia (72.9%). Dysphagia was present in 30% of patients. Thirty two percent of patients had proximal carcinoma, 63.2% had distal carcinoma and in 4.7% the whole stomach was involved. Patients with distal carcinoma had a longer history (P less than 0.01) and were more likely to present with weight loss (P less than 0.001), anorexia (P less than 0.005), abdominal pain (P less than 0.05) and abdominal lump (P less than 0.05), compared to proximal carcinomas. Dysphagia was, however, more likely to be present in patients with proximal carcinomas (P less than 0.001).

From 1972 to 1989, 20 cases of tuberculous peritonitis were seen in Tokyo Metropolitan Geriatric Hospital. In 13 patients the diagnosis of tuberculous peritonitis was made only at autopsy, which in 7 patients was made during life. Of all 20 cases the mean age was 78 years, with a range of 63 to 96 years. There were no differences in mean ages between autopsied patients and clinically diagnosed patients. There were 11 male and 9 female patients. In autopsied patients 6 were male and 7 were female. Of the clinically diagnosed patients 5 were male and 2 were female. Seven of 13 patients who were diagnosed at autopsy had liver diseases, for example liver fibrosis, liver cirrhosis, hepatocellular carcinoma or chronic hepatitis. In 4 of 7 patients who were diagnosed during life, ileus was also present and their diagnosis of tuberculous peritonitis was made at operation. Only 6 patients had tuberculin test with intermediate strength PPD. There were no positive reactions. In patients who were diagnosed during life, abdominal swelling, anorexia, abdominal pain and fever, the most common clinical manifestations, were seen in 100%, 75%, 50% and 86%, respectively. In contrast, they were seen in 33%, 57%, 0% and 62%, respectively, in autopsied patients. The volume of ascitic fluid varied from zero to 3000 cc. Total white-cell count in the peripheral blood was within or lower than the normal range in 85% of all 20 cases. The lymphocytes count in the peripheral blood was decreased in 95% of all 20 cases. There were no characteristic features in the serum biochemical analysis.(ABSTRACT TRUNCATED AT 250 WORDS)

A 50 year old man with a two month history of upper abdominal pain and a one month history of anorexia and weight loss, presented with icterus and evidence of peritonitis. Laparotomy revealed biliary peritonitis which had been caused by a rupture of the fundus of the gallbladder. The common bile duct was dilated and there was a large growth in the head of the pancreas with multiple hepatic metastases. A cholecystojejunostomy and gastrojejunostomy were done and the patient had an uneventful recovery.

In this study we examined the clinical and laboratory findings of 80 in-patients. There is an important difference between sexes (p greater than 0.05). Comparison of ages showed that 7-30 age is more vulnerable than the older group. We found clinical symptoms of fever, chills, headache, abdominal pain, disturbances in bowel function, nausea, vomiting, anorexia, and lassitude in the first two weeks more frequently when compared with the 3rd, 4th, 5th weeks of illness (p less than 0.001). Where physical finding of rose spots, discordant pulse rate are important in the first two weeks (p less than 0.001). Abdominal discomfort is an important symptom both in the first two and in the last three weeks (% 40.3 and % 36 respectively). Hepatomegaly and splenomegaly, were found more frequently in the last three weeks. According to laboratory findings of anemia, leukopenia, increased erythrocyte sedimentation rate and positive blood and feces cultures there is no important difference between the first two and last three weeks (p greater than 0.05). Increase in polynuclear leucocytes is important for the first two weeks, and increase in lymphocytes is important in the last three weeks (p less than 0.001). Positivity of group agglutination tests is 57%, in the first two weeks and 83% in the last three weeks. This difference is found to be important.

Thirty human anthrax cases were reported from Ramabhadrapuram village of Chittoor district in Andhra Pradesh during November-December, 1989. These cases occurred following an epizootic of anthrax among cattle and sheep of the village and ingestion of contaminated meat by the villagers. The overall attack rate was 24.39 per cent with a case fatality of 16.67 per cent. All age groups and both sexes were affected. Ten cases were of cutaneous form with typical black eschar formation which were confirmed bacteriologically. Fever and headache were common systemic manifestations. They responded well to penicillins and there was no mortality. The possibility of human to human spread is suggested. The twenty cases of internal anthrax comprised intestinal, septicemic, peritonitis, meningeal and pulmonary forms. Sub-clinical forms also occurred. Fever, abdominal pain, ascites, anorexia and vomiting were notable features. Diagnosis was made clinically and also on epidemiological basis. All deaths during this outbreak occurred in women with internal anthrax, the case fatality rate for the latter being 25 per cent. Prophylactic administration of penicillin was done for individuals at risk.

A prospective study of 41 patients (24 male and 17 female) aged over 40 years with iron deficiency anemia and hookworm infection was performed by endoscopy and barium enema to determine the incidence of GI lesions. Alcohol ingestion, smoking, abdominal pain, anorexia, loss in weight, bowel habit change, analgesic consumption and stool occult blood test were analyzed for their positive predictive value of GI lesions. The mean age of the patients was 62.8 years (SD = 10.1). The mean hemoglobin was 5.99 gm.% (SD = 1.9). Twenty patients (48.8%) had GI lesions. The lesions included 10 erosive gastritis, 1 erosive duodenitis, 5 gastric ulcers, 2 duodenal ulcers, 1 carcinoma of stomach and 1 carcinoma of colon. Gastric ulcer, duodenal ulcer and carcinoma were regarded as significant lesions. Abdominal pain was found in 16 of the 20 patients with GI lesions and 8 of the 21 without GI lesion (Chi square with Yate's correction, x2 = 5.78 p = 0.02). Four of the 17 patients without pain had GI lesions but only one of these 4 (5.8%) had gastric ulcer. Abdominal pain had an 80% sensitivity and 62% specificity for the positive prediction of GI lesions based on the above findings. GI investigation is recommended for all patients with abdominal pain. In those without pain, treatment of hookworm and iron therapy with follow-up may be justified.

Fifty Thai patients with Parkinson's disease of all staging were allocated for 10 mg/day L-deprenyl therapy as the monotherapy (6 patients) and adjunctive therapy for at least two months. The assessment of this open study included the activities of daily living using Schwab/England Scale, Hoehn and Yahr staging and Unified Parkinson Disease Rating Scale (UPDRS) by comparison of the initial and after two month of treatment scores. There was improvement of both Schwab/England Scale and UPDRS in Hoehn and Yahr stage I, II and III patients. In stage IV and V patients there was no benefit of L-deprenyl therapy of both clinical and statistical analyses. Adverse effects of L-deprenyl were not serious. There were dry mouth (20%), anorexia (10%), nausea and vomiting (8%), insomnia (6%), lightheadedness (4%) constipation (4%), abdominal pain (2%), generalised ache (2%). We conclude that L-deprenyl therapy is effective, safe, but costly. It is more effective in early Parkinsonism. The effectiveness of L-deprenyl is less in more advanced states of Parkinson's disease. Thus, selection of the appropriate Parkinsonian patient for L-deprenyl therapy is vital.
