Diagnostic criteria for allergic fungal sinusitis have not been established, and clinical information consists primarily of isolated case reports. We proposed five diagnostic criteria for allergic fungal sinusitis including: (1) the demonstration of the characteristic eosinophil-rich allergic mucin visually or histopathologically, (2) a positive fungal stain or culture from the sinus at surgery, and (3) the absence of immunodeficiency or diabetes. With these criteria, seven patients in our metropolitan area with allergic fungal sinusitis were identified in a short period. Initial symptoms in our seven patients reflected those in 99 case reports in that two children were first seen with proptosis, one child and three adults with nasal congestion, and one adult with symptoms of chronic sinusitis. All had pansinusitis as shown on x-ray films. Six patients were atopic, five had nasal polyposis, and five had Curvularia species cultured from the sinuses. Infections with Bipolaris species, asthma, and chronic sinusitis were less common in our patients than in those previously reported. Recurrent symptoms and additional surgery sometimes resulted when the diagnosis was delayed by failure to obtain silver stains for fungus on surgical material sent for histopathologic review. Sinus tomography showed that the fungal material in the sinuses was of high density, which distinguished it from polyps or bacterial exudate. Bony compression, erosion, and rupture of the sinus walls were common. Results of IgE levels, precipitin determinations, and eosinophil counts were variable in both our patients and those in the literature. On the basis of our review, we believe that the simple diagnostic criteria proposed are appropriate for both research and clinical purposes.

From 1974 to 1990, 336 Bacteroides isolates were obtained from 312 specimens from 274 patients. They comprised 180 (54%) B. fragilis isolates, 55 (16%) B. theta-iotaomicron, 36 (11%) B. vulgatus, 34 (10%) B. distasonis, 21 (6%) B. ovatus and 10 (3%) B. uniformis. Infections in 253 (92%) patients were polymicrobial, but in 21 (8%) children, a Bacteroides sp. was isolated in pure culture. Most Bacteroides isolates were from peritoneal fluid (114), abscesses (110), wound infections (20), blood cultures (10) and from patients with pneumonia (14) or chronic otitis media (8). Predisposing conditions were present in 145 (53%) children; these were previous surgery (46), trauma (28), malignancy (21), prematurity (19), immunodeficiency (18), steroid therapy (12) foreign body (10), diabetes (9) and sickle cell disease (7). The micro-organisms isolated most commonly mixed with Bacteroides spp. were anaerobic cocci (221), Escherichia coli (122), Fusobacterium spp. (38) and Clostridium spp. (30). All patients received antimicrobial therapy in conjunction with surgical drainage or correction of pathology in 197 (72%) cases. All but 12 (5%) patients recovered. These data illustrate the importance of Bacteroides spp. in infections in children.

The results of observation of 132 patients with local purulent inflammation elapsing on the diabetes mellitus background, treated with the help of detoxication (hemosorption, endolymphatic therapy, UV blood irradiation, enterosorption) methods were analyzed. Local treatment using these methods was conducted in the abacterial environment and with the inhibitor trielin application. This gave the possibility to correct effectively the endotoxicosis, secondary immunodeficiency, to prevent the sepsis origin and to improve significantly the results of patients treatment.

Pentamidine is known to cause severe dysglycaemia by damaging beta-cell function of the pancreas. The exact mechanism still remains unclear. We report the case of a 53-year-old man infected with the human immunodeficiency virus who developed insulin-dependent permanent diabetes mellitus 3 days after starting intravenous treatment with pentamidine for pneumocystis carinii pneumonia. Discharged from hospital the daily need of insulin increased continuously over one year now requiring an average dose of 80 units per day. So far, a number of cases of insulin-dependent diabetes mellitus following pentamidine therapy has been reported, but long-term observations are rare.

Bloom's syndrome is a rare autosomal recessively transmitted disorder, the main clinical feature of which is small body size. A sun-sensitive, erythematous facial skin lesion, an excess of well-demarcated hyper- and hypopigmented skin lesions located anywhere on the body, and increased numbers of bacterial infections due to immunodeficiency are accompanying features of diagnostic value. In Bloom's syndrome, the complications are formidable: cancer, chronic lung disease, and diabetes. Cancers of the types and sites seen in the general population arise frequently and unusually early. Bloom's syndrome cells are hypermutable, and excessive numbers of somatic mutations are responsible for many of the clinical features. The clinical diagnosis is confirmed cytogenetically by demonstrating a characteristic chromosome instability.

This article describes the clinical, epidemiologic, laboratory, and treatment characteristics of pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) in Eastern North Carolina, a primarily rural area. The database was obtained for 1988-1992 from the University Medical Center of Eastern North Carolina-Pitt County and East Carolina University School of Medicine (the tertiary care referral center for this region). One hundred thirty-eight culture-positive patients were enrolled in the study; 56% were PTB and 44% were EPTB. African-American males constituted 59% of the population. Sixty-nine percent of the patient base were uninsured. There was a bimodal age distribution of < 40 and > 60 years of age. Factors associated with PTB (reported as odds ratios) were white males (2.5), diabetes mellitus (5.4), and cancer (5.1). Factors associated with EPTB (reported as odds ratios) were African-American females, positive human immunodeficiency virus (HIV) serology (8.7), low hematocrit (32.6), and elevated alkaline phosphatase (199). This study emphasizes that in the latest resurgence of tuberculosis, impoverished rural areas, which have been ignored in earlier and present control efforts, are important reservoirs of disease.

Heroin-associated nephropathy (HAN), a complication of intravenous heroin abuse, was initially recognized at Kings County Hospital in Brooklyn, NY, in the early 1970s. Our recent experience indicates that after a steady incidence of new cases of HAN throughout the mid-1980s, a sharp decrease in incidence of new cases occurred starting in 1989. We sought to explore possible explanations for what amounts to disappearance of a previously prevalent disease. By means of retrospective analysis of a hospital-specific registry of new cases of end-stage renal disease (ESRD) at Kings County Hospital in Brooklyn, incidence curves from 1981 through 1993 for new cases of HAN, diabetes-induced renal disease, and human immunodeficiency virus-associated nephropathy were constructed. From hospital computer records, the number of admissions directly related to opioid abuse were extracted and charted. Unpublished surveillance records of the New York State Office of Alcoholism and Substance Abuse Services as well as reports from the New York City Department of Health, Office of AIDS Surveillance and the US Department of Justice Drug Enforcement Administration were used to determine the pattern of change in the prevalence of heroin abuse. Additionally, we used analysis of "street" heroin by the Drug Enforcement Administration to draw curves detailing drug cost and purity in New York City. There were no new cases of ESRD due to HAN for the years 1991 through 1993. The rates for new cases of ESRD due to diabetes and hypertension remained relatively constant throughout this interval.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1974 to 1994, 504 isolates of Prevotella and Porphyromonas spp. were obtained from 435 (21%) of 2033 specimens from 418 children. They included 160 (32%) Pr. melaninogenica, 105 (21%) Pr. intermedia, 84 (17%) P. asaccharolytica, 58 (12%) Pr. orisbuccae, and 58 (12%) Pr. oralis. Most Prevotella and Porphyromonas spp. were isolated from abscesses (176), pulmonary infections (85), ear infections (82), wound infections (44), peritonitis (38), paronychia (15) and chronic sinusitis (14). Predisposing conditions were noted in 111 (27%) of the cases; these included previous surgery in 41 (10%), foreign body in 36 (9%), neurological deficiencies in 29 (7%), immunodeficiency in 21 (5%), steroid therapy in 12 (4%), diabetes in 8 (2%) and malignancy in 7 (2%). Prevotella and Porphyromonas spp. were the only isolates in 14 (3%) patients, and mixed infection was encountered in 404 (97%). The micro-organisms most commonly isolated with Prevotella and Porphyromonas spp. were anaerobic cocci (393 isolates), Fusobacterium spp. (108), Bacteroides spp. (B. fragilis group) (95), Escherichia coli (56) and other gram-negative anaerobic bacilli (52). Most Bacteroides spp. and E. coli were isolated from intra-abdominal infections and skin and soft tissue infections around the rectal area, whereas most Fusobacterium spp. were isolated from oropharyngeal, pulmonary and head and neck sites. beta-Lactamase production was detected in 191 (38%) Prevotella and Porphyromonas isolates from all body sites. All patients received antimicrobial therapy, and surgical drainage was performed in 173 (41%) cases. Four patients died from their infection. These data illustrate the spectrum and importance of Prevotella and Porphyromonas spp. in infections in children.

The aim of this study was to identify and describe possible alterations of bone histomorphometry in patients with human immunodeficiency virus (HIV-1) infection and to assess the relation between these alterations and disease severity. Forty-four HIV-1-infected patients seen successively at our hospital were evaluated for the study. In an attempt to avoid confounding factors as far as possible, we excluded patients who fulfilled any of the following criteria: age less than 18 or greater than 40 years; recent history of extended bed rest; previous diagnosis of metabolic bone disease, renal insufficiency, or hepatic failure; clinical or echographic signs of liver cirrhosis; diabetes mellitus or previous diagnosis of other endocrine diseases; drug therapy that could act on bone metabolism; and/or moderate to severe nutritional alteration. Twenty-two patients (13 men, 9 women; age: 27.9 +/- 4.1 years, mean +/- standard deviation) were included in the study. Plasma and urine biochemistry and calcium-regulating hormones were determined. Bone mineral content was measured on vertebrae L2 to L4 and on the neck and intertrochanteric areas of the femur by dual-photon absorptiometry. A transiliac bone biopsy was performed after double-tetracycline labelling, with histomorphometric study of undecalcified bone. Serum osteocalcin was found to be lower in patients who, according to the Centers for Disease Control (CDC) classification, had greater disease severity, and showed a positive correlation with the number of CD4+ T lymphocytes. No alterations in bone densitometry were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Recently, a new syndrome of early onset cerebellar ataxia with hypoalbuminemia (EOCA-HA) was reported in Japan. The clinical features of EOCA-HA overlap with those of Friedreich's ataxia (FA), and primary hypoalbuminemia is a characteristic laboratory finding of this syndrome. Genetic linkage analysis of EOCA-HA including this newly reported family revealed that the gene for EOCA-HA is located on the long arm of chromosome 9 as FA. However, several recombination events were observed between D9S15 in EOCA-HA, whereas no recombination events were seen in FA. We report on two siblings with EOCA-HA and discuss the clinical and laboratory features. The patients were a 25-year-old man (patient 1) and a 23-year-old man (patient 2). Their parents marriage was non-consanguineous. The mode of inheritance is compatible with autosomal recessive mode. Clinically, they showed cerebellar ataxia as the initial symptom in the late infantile period and subsequently showed choreoathetosis and ocular motor apraxia at the age of approximately fifteen years. Deep tendon reflexes were reduced in late infancy and finally disappeared. Amyotrophy and sensory impairment of the legs developed at approximately twenty. Abnormal electrocardiogram and diabetes mellitus were not observed. On X-ray CT scan or MRI, the cerebella of both patients were mildly atrophic. Clinical features in these siblings were indistinguishable from those of ataxia telangiectasia, but immunodeficiency syndrome was absent.(ABSTRACT TRUNCATED AT 250 WORDS)
