This study was carried out retrospectively to evaluate the pattern of diseases associated with fever among infants aged 1-6 months at Gunung Wenang General Hospital Manado. During the period of January 1988-December 1989, 189 infants with age ranging 1-6 months, were evaluated. Diseases associated with fever predominantly occurred in infants of 3 months old (73.0%). The final clinical diagnosis of diseases associated with fever were gastroenteritis (39.15%), pneumonia (28.05%), meningitis (9%), respiratory tract infection (15.4%), post vaccination (4.20%) and septicemia (4.3%). The fever ranged from 37.8-38.3 degrees C (38%), 38.4-39.5 degrees C (49%), 39.6-41 degrees C (10%) and more than 41 degrees C (3%). The elevated body temperature was significantly related to the duration of fever (p 0.01). Increased erythrocyte sedimentation rate and thrombocytopenia were not correlated significantly (p greater than 0.05) with elevated body temperature while the total white cell count had a significant relationship (p less than 0.05).

Twenty patients with peripheral arteritis due to an infectious disease were studied with the purpose to detect the etiological agent in the vessels belonging to ischemic areas; to establish the relationship between the onset and evolution of the ischemic lesions and the infectious disease; and to verify the appropriateness of the treatment with anticoagulants. Ten patients had meningococal disease with positive blood culture for Neisseria meningitidis. The meningococci were found in vessel walls of ischemic areas. The cutaneous lesions had sudden onset and a rapid evolution. Five patients had pneumonia or gastroenteritis. No microorganisms were detected in the vessel walls of the ischemic areas. The cutaneous necrotic lesions appeared from two to six days after the infectious disease was diagnosed. Therefore, heparinization was considered appropriate to block the extension of the disseminated intravascular coagulation secondary to the vasculitis. Three patients had, probably, post-streptococcal sensibilization arteritis and two post-measles arteritis. No etiological agent was identified in the vessel walls. The necrotic lesions of the extremities appeared from five to 21 days after the clinical course of the infection. The lesions had the complete evolution in a period from one to four days. It was considered appropriate to start the heparinization in the evolutive period of the peripheral lesions in an attempt to reduce the ischemia by the interruption of the intravascular coagulation related to the vasculitis. In heparinized patients in whom the necrotic lesions did not extend completely in the extremities, the evolution to irreversible gangrene and limb loss did not occur.(ABSTRACT TRUNCATED AT 250 WORDS)

Many discriminative experimental animal models of infection have been utilized in the evaluation of newer fluoroquinolones. In vivo efficacy of many of the newer agents has been shown in experimental models of meningitis, endocarditis, pneumonia, urinary tract infections, pyelonephritis, osteomyelitis, abscesses of various types, septic arthritis, gastroenteritis, salmonellosis, listeriosis, tuberculosis, syphilis, sinusitis, prostatitis and burn wound sepsis, among others. This review focuses on recent developments in a few selected areas. Although the limitations of animal model studies are well described, these results provide a rationale for the appropriate clinical usage of the newer fluoroquinolones in humans.

Two cases of campylobacter septicaemia are described. The first, caused by Campylobacter laridis was associated with gastroenteritis and occurred in a healthy individual. In the second case, a catalase negative species, C. mucosalis was isolated from blood in an immunocompromised patient with symptoms of pneumonia. Both campylobacter strains grew faintly under the routine culture conditions used. Improved diagnostic procedures for Campylobacter species may thus be warranted.

Eleven children were identified as being seropositive for HIV-1 at the Ethio-Swedish Children's Hospital, Addis Abeba, Ethiopia between January 1988 and September 1989. The diagnosis was confirmed by both ELISA and Western blot methods performed at the National Research Institute of Health, Special Laboratory for AIDS. The mean age was 2 years and 5 months, with a range of 1 week to 10 years. There were 7 boys and 4 girls. The most common admitting diagnoses were pneumonia (5), gastroenteritis (5), marasmus (5), disseminated tuberculosis (4), and abandonment (3). One patient had extensive facial molluscum contagiosum. Symptoms at admission or during hospitalization included diarrhoea (9), failure to thrive (8), fever (7), and cough (7). Physical findings included hepatosplenomegaly (5), lymphadenopathy (3), and oral candidiasis (2). No patient with an opportunistic infection or radiographic evidence of lymphocytic interstitial pneumonitis (LIP) was identified. Five patients were classified as marasmic and 4 as underweight. Evidence suggestive of encephalopathy (developmental delay and/or microcephaly) was present in 5 patients. The VDRL was non-reactive in the 5 patients in whom it was tested. Nine children were presumed to have acquired the infection by perinatal transmission, though the passive transfer of maternal antibodies or postnatally acquired infection could not be excluded. One child was thought to have acquired the infection by blood transfusion. Three children died during their hospital stay. Paediatric HIV infection exists in Ethiopia; however, these children do not present with characteristic opportunistic infections but with signs and symptoms reflecting the most common paediatric problems seen in the country. Prevention of HIV infection in children entails the prevention of infection in women of childbearing age, counselling of infected women, and effective screening of blood products.

Information from the National Salmonella Shigella Center (NSSC), Thailand indicated that the most frequently isolated Salmonella serotype from humans during 1974-1975 was Salmonella typhi (33.1%), during 1976-1982 was S. krefeld (26.6%) and during 1983-1987 was S. derby (12.6%). Antimicrobial susceptibility study of various Salmonella serotypes indicated that S. krefeld was the serotype with multiple drug resistance persisting for the longest period of time. Human salmonellosis due to S. krefeld is very rare. During 1976-1978, a large outbreak of S. krefeld gastroenteritis occurred in Thailand, mainly in children. The outbreak spread countrywide and is currently endemic. Gastrointestinal symptoms are severe in young infants. Systemic invasion with bacteremia, meningitis and pneumonitis were reported. The antimicrobial susceptibility pattern of isolates varied from sensitive to multiply drug resistant. The common antibiotic resistances were to ampicillin (75-92%), chloramphenicol (33-75%), kanamycin (67-90%) and sulfamethoxazole-trimethoprim (15-52%). Resistance to gentamicin and sulfamethoxazole-trimethoprim declined after the period of the epidemic. Antimicrobial resistance patterns of 150 S. krefeld strains isolated in Thailand during 1978-1987 showed multiple drug resistance with up to seven drugs. The most common patterns were ApCmKmSuTp and ApCmKmSmSuTc.

This study seeks to assist in setting priorities for assessing medical practices and technologies when assessment resources are scarce. It develops an objective index of expected gain from technology assessment, using modified DRG-level data on hospitalizations in NY State. The index uses standard economic concepts to combine measures of resource use, the coefficient of variation in use rates across regions, and the rate at which the incremental value of a medical intervention changes as its rate of use changes, providing a dollar-valued welfare loss from variations. For the entire US in 1987, the highest index occurred for coronary artery bypass graft ($0.95 billion per year), but most of the high-index interventions were nonsurgical, including hospitalizations for psychosis ($0.74 billion per year), cardiac catheterization ($0.62 billion per year), chronic obstructive lung disease ($0.55 billion per year), angina pectoris ($0.46 billion per year), adult gastroenteritis ($0.38 billion per year), adult pneumonia ($0.32 billion per year) and medical back problems ($0.28 billion per year). The top 25 interventions create an annual welfare loss of exceeding $7 billion. The present value of convincingly assessing the correct way to use these interventions sums many years of annual gains from eliminating these welfare losses. The gains from eliminating unexplained variation in medical practices appear greatly larger than costs of necessary studies.

Two distinct processes contribute to the spectrum of human cytomegalovirus (HCMV)-induced pathology. In the first instance, cytopathic effects appear to occur as a direct result of virus replication. This type of disease is characterized by persistent HCMV infection of neural or gastrointestinal tissue, which results in HCMV retinitis, encephalitis, hepatitis, or gastroenteritis. Direct cytopathic effects of HCMV are associated with congenitally acquired or acquired immune deficiency syndrome-related manifestations of HCMV infection. A second type of HCMV-associated disease process is driven by immunopathologic mechanisms and results in variable mononucleosis-like syndromes and/or pneumonia in normal or partially immunosuppressed individuals. Human cytomegalovirus-associated interstitial pneumonia appears to derive from a combination of these two types of disease processes. Here, persistent viral infection, immunopathologic mechanisms, and virus-induced expression or repression of cellular genes each constitutes an important factor in pathogenesis. An understanding of the multiple underlying mechanisms of pathogenesis is crucial to devising optimum treatment approaches.

The clinical manifestations of cytomegalovirus (CMV) infection in persons with AIDS are described, and recent advances in the management of these syndromes with antiviral agents are reviewed. CMV infection is the most common serious opportunistic viral infection in AIDS patients. Clinical manifestations include chorioretinitis, gastroenteritis, hepatitis, pneumonia, CNS infection, adrenalitis, and a wasting syndrome. The diagnosis of CMV infection requires laboratory demonstration of a serologic response to the virus, detection of viral components or products, or isolation of the virus. Ganciclovir is an acyclic nucleoside analogue marketed for the treatment of CMV-related retinitis in immunocompromised hosts. After i.v. ganciclovir induction therapy, more than 80% of patients show improvement or stabilization of retinitis. Relapse is common in AIDS patients, however, and low-dose i.v. maintenance therapy is recommended. The most serious dose-limiting effect is neutropenia. Intravitreal injection of ganciclovir has been well tolerated and efficacious. Ganciclovir has shown some efficacy in the treatment of other life-threatening CMV infections, especially gastroenteritis, but data are limited. Ganciclovir-resistant strains have been reported. Foscarnet, a pyrophosphate analogue with activity against both human CMV and human immunodeficiency virus, is undergoing clinical trials. Foscarnet has shown promise in the therapy of CMV-related retinitis, but results for other CMV infections are disappointing. Nephrotoxicity is the major dose-limiting effect. AIDS patients with sight-threatening and rapidly progressive CMV-related retinitis should be treated with ganciclovir. Foscarnet may offer an alternative when it becomes available. More must be learned about the efficacy of these drugs in the treatment of CMV infection in patients with AIDS.

Cytomegalovirus (CMV) infection in patients with the acquired immunodeficiency syndrome (AIDS) can present as either disseminated disease, pneumonitis, retinitis, gastroenteritis, neuropathy, or a subclinical infection. We report a patient whose initial manifestation of CMV infection was severe central airways obstruction due to necrotizing tracheitis. At bronchoscopy, the lesion appeared deeply ulcerated, distinctly different from previously described airway lesions in patients with AIDS. Mucosal biopsies showed characteristic intranuclear and intracytoplasmic inclusions and cultures yielded only CMV. The patient responded partially to ganciclovir, steroids, and antibiotics against suspected anaerobic superinfection but died as a result of central nervous system disease believed due to toxoplasmosis or lymphoma. CMV infection of the upper airway should be considered in the patient with AIDS presenting with atypical cough or stridor and ulcerated endobronchial lesions.
