Infections caused by Chlamydia pneumoniae were first described in 1985. The infection can cause common cold, sore throat, hoarseness, cough, headache, fatigue and sometimes influenza-like illness. Examination can indicate serous otitis media, sinusitis, laryngitis, bronchitis and pneumonia. The course can be long and relapsing. The recommended drugs for treatment are tetracycline or erythromycin for at least two weeks. Five verified cases are described in the article, four of them with symptoms from the upper respiratory tract only. It is concluded that Chlamydia pneumoniae is a not unusual cause of upper airway diseases. Up to now the diagnosis can best be verified by micro immunofluorescence. The authors call for a rapid and reliable test for use in physician's office. It is proposed that infections caused by Chlamydia pneumoniae be termed TWAR.

Energy conservation, insufficient ventilation and introduction of new building materials are accompanied by increasingly frequent complaints of increasingly frequent mucosal irritation, headache and lethargy among occupants, commonly called "sick building syndrome". Infections and toxic allergic reactions may be caused by infected humidifiers. The article includes a review of symptoms and causes. Many of the complaints can be prevented. Combined efforts by medical and technical personnel are necessary in diagnosing and solving indoor climatic problems.

Clinical features, findings of diagnostic studies, results of therapy, and prognostic factors were analyzed in 45 patients with brain abscesses. The number of patients diagnosed yearly has increased since CT scanning became available, but despite the enhanced sensitivity, the time from either onset of symptoms or hospital admission until initiation of therapy was not decreased and there was no dramatic effect upon morbidity or mortality in this series. Infections of paranasal sinuses, ears, lungs, and odontogenic foci were predisposing factors in approximately 70% of cases. Single abscesses, present in 75% of patients, were distributed equally in both hemispheres, with more than half in the frontal and parietal lobes. Common signs and symptoms included headache, fever, chills, seizures, nausea, vomiting, altered sensorium, nuchal rigidity, and localizing neurologic signs. Blood cultures were positive in 11%. Lumbar puncture rarely provided data from which a diagnosis could be established; CSF cultures were positive in only 7% of patients, and there was a 15% temporally associated incidence of brain herniation and death. Diagnostic information was most readily obtained using imaging techniques such as CT and 99mTc scanning, and arteriography was invasive and of no added value. CT scans are however, often initially negative in patients presenting with clinical signs of meningitis presumably following rupture of an abscess into the subarachnoid space, and the average time for changes to appear on CT scan is 9 days. It is, therefore, recommended that when the clinical assessment suggests the possibility of brain abscess the patient be treated empirically with antibiotics and that lumbar puncture be performed only after thoughtful assessment of the risk-to-benefit ratio for each patient. Causative organisms were isolated from more than 80% of abscesses despite prior antibiotic treatment; more than half grew a single pathogen, most commonly streptococci. Anaerobic and microaerophilic bacteria accounted for 62% of all isolates, and were the only organisms in 33% of patients. Computerized tomographic scans in 30 patients showed "ring-enhancing" lesions, nodular enhancement, or areas of low attenuation. Complete resolution of abscesses on CT scans rarely occurred during hospitalization and took as long as 5 months. Decrease in the size of abscesses on CT scan correlated well with clinical improvement and was seen within a week when abscesses were excised, but was often not obvious for 6 to 8 weeks if antibiotics were used alone.(ABSTRACT TRUNCATED AT 400 WORDS)

Tick-bite fever, the variety of tick typhus occurring in southern Africa, is caused by Rickettsia conori var. pijperi and is transmitted by hard or ixodid ticks. It is usually a mild disease, especially in children and young adults, but in middle-aged and elderly patients (and sometimes in young adults) it may assume a severe form. This is characterized by high fever, severe headache, delirium, stupor and occasionally coma, and a profuse maculopapular rash which becomes haemorrhagic and is associated with petechiae in the skin and later, but rarely, by the development of gangrene of the fingers and toes. During these severe attacks the central nervous system may be involved and marked disorders of liver and kidney function sometimes lead to kidney failure and the need for treatment and dialysis in an intensive care unit. Three illustrative cases are described in which diagnosis was delayed. One patient died; 2 patients responded to administration of tetracycline. The danger of allowing tick-infested dogs onto one's bed is stressed. Infections transmitted by dog ticks tend to be more severe than those acquired via ticks from the bushveld, possibly because they so often occur in middle-aged and elderly patients. Serological tests have recently indicated that there are antigenic differences between 'suburban' and 'bushveld' strains; these clearly require further study.

Infections caused by Actinomyces organisms have been demonstrated to occur in association with IUD use. Uterine actinomycosis infection is usually superficial, but it is potentially invasive. It may prove fatal. When Actinomyces is detected in a vaginal Papanicolaou smear, establishment of the correct diagnosis followed by IUD removal and appropriate antibiotic therapy are recommended. A case history is presented of a 28 year old woman who had been using an IUD and who had systemic Actinomyces infection and a brain abscess develop several years after removal of her uterus and fallopian tubes. The woman was referred to the Johns Hopkins Hospital in Baltimore in 1977 for evaluation of headaches and grand mal seizures. 4 years earlier, in 1973, she had been seen at another hospital with a recent weight loss of 18 kg. She was found to have a tubo-ovarian abscess, for which she underwent a hysterectomy, bilateral salpingectomy, and unilateral oophorectomy. At the time of surgery, an IUD was in place. A histopathological diagnosis of botryomycosis tubo-ovarian abscess was made on submitted tissues. She received no antibiotic therapy. In 1975, pulmonary infiltrates developed that were attributed to bronchopneumonia. She was treated with a short course of tetracycline hydrochloride. Later that year she was thought to have sarcoidosis and was treated for 1 year with several doses of prednisone. Clinically, her condition remained stable until March 1977, when a pyogenic subcostal abscess was drained. In July 1977, she had headache, dizziness, generalized seizures, and an incomplete right homonymous hemianopsia develop. A craniotomy for excision and drainage of an abscess was performed. The presence of Actinomyces israelii in brain tissue was confirmed by direct immunoflourescence using specific antiserum. It was confirmed that Actinomyces had been present at the time of her 1st surgical procedure. She was treated with high doses of intravenous penicillin G potassium for the first 4 weeks, followed by lower doses of oral penicillin V potassium for an additional 15 months. She recovered completely, except for a persistent right homonymous hemianopsia. The case illustrates that systemic dissemination and potentially life threatening complications of uterine actinomycosis can occur if the infection is unrecognized and/or inadequately treated.

We carried out a randomized prospective trial to compare OKT3 (5 mg/d, 51 patients) with ATG-Fresenius (ATG-F, 4 mg/kg/d, 53 patients) for induction therapy after renal transplantation, concerning side effects, rejection, and infection incidence within a one year follow-up period. Concomitant immunosuppression included azathioprine/steroids from day 0 and cyclosporine A from day 4. OKT3 patients experienced significantly more and more-severe side effects, particularly pyrexia, headache, and pulmonary fluid overload. One-year graft survival was excellent in the ATG-F group (91%), but only 78% in the OKT3 group (P < 0.05) due to a series of rejections that occurred beyond day 100; patient survival (96% and 92%) was similar in both groups. OKT3-treated patients experienced more biopsy-proven rejections (0.6 +/- 0.1/pt.) than ATG-F patients (0.3 +/- 0.1, P < 0.05), and there was a similar, albeit not significant trend in clinical rejections (OKT3: 1.1 +/- 0.2/pt.; ATG-F: 0.8 +/- 0.1/pt.). Infections were more common in the OKT3 group (OKT3: 3.2 +/- 0.3, ATG-F: 2.0 +/- 0.2, P < 0.05), although this was entirely attributable to "minor" infections. On days 1 through 6, CD3 counts were more profoundly depressed with OKT3 therapy. Beyond day 10, however, CD3 counts were lower in the ATG-F group, as were CD2 counts, CD4 counts, and the CD4/CD8 ratio, suggesting a more prolonged immunosuppressive effect of ATG-F. Sensitization occurred more frequently with OKT3 (31%) than with ATG-F (10%), but was usually irrelevant, except in two patients (one in each group), whose grafts were lost because of immunization against OKT3 and ATG-F, respectively. In conclusion, a 7-day induction therapy with OKT3 does not improve outcome or diminish immunological graft loss when compared with ATG-F, but is associated with more rejections, infections, and side effects. ATG-F appears to be preferable for induction immunosuppression after renal transplantation.

Between 1987 and 1991 leptospirosis in 32 Dutch travelers was diagnosed. Infections were acquired predominantly in Thailand and other Southeast Asian countries. Contact with surface waters could be confirmed in all but one case. Fever, headache, and myalgia were the most common complaints. Signs included conjunctival injection and lymphadenopathy in 11 patients each, jaundice in 8, and nuchal rigidity in 3; renal function was impaired in 8. Leptospires were isolated from the blood or urine of nine patients. Thirty-one patients developed an antibody response. Classification of strains identified a variety of serogroups. Although only 14 patients received adequate treatment, all patients recovered completely. Since the number of patients with imported leptospirosis is increasing and the signs and symptoms of the disease are not specific, leptospirosis should be included in the differential diagnosis when a traveler returns from the Tropics with fever.

The purpose of this study was to review our experience with the use of OKT3 (a murine monoclonal CD3 antibody) used as immune prophylaxis for pediatric heart transplant recipients. Orthotopic heart transplantation was performed in 18 pediatric patients, 8 girls and 10 boys, ranging in age from 17 days to 17 years. OKT3 therapy was initiated intraoperatively at a dose of approximately 0.2 mg/kg and was administered at a dose of approximately 0.1 to 0.2 mg/kg/day for a period of 11.5 +/- 2.5 days. Daily average OKT3 levels were 1132 +/- 469 ng/ml. Side effects that occurred during OKT3 therapy were fever (59%), diarrhea (24%), headaches (24%), vomiting (18%), encephalopathy (12%), pulmonary edema (6%), and rash (6%). Infections occurred in 24% of patients, all within 6 months of transplantation. In the first year after transplantation, patients experienced 3.4 +/- 2.4 episodes of mild rejection and 1.0 +/- 0.8 episodes of moderate rejection. No patient experienced severe rejection. Five of the surviving 14 patients (36%) have been weaned from chronic steroid therapy, and 42% are being maintained on alternate-day prednisone at a dose of 0.06 +/- 0.02 mg/kg/day. Coronary artery disease developed in three patients; two of whom died. Actuarial survival was 83% at 1 year and 73% at 2 years. This report shows that OKT3 prophylaxis in pediatric heart transplantation can be used with acceptable short-term adverse side effects and overall survival.

Infections due to nontuberculous mycobacteria (NTM) are especially common in patients with AIDS. Meningitis due to NTM, however, is rare. A search for CSF cultures positive for NTM over the past 11 years at our hospital yielded 16 cases. Of these, 15 were caused by Mycobacterium avium-intracellular (MAI), and one was caused by M fortuitum. All patients with MAI infection had widespread dissemination and at least one risk factor for AIDS. Clinical features included weight loss, altered mentation, and seizures. Analysis of cerebrospinal fluid revealed a mildly elevated leukocyte count with lymphocyte predominance and normal protein and glucose values. All direct smears were negative for acid-fast bacilli. In-hospital mortality was 67%. The patient with infection due to M fortuitum had a preexisting diagnosis of AIDS and had a right upper lobe pneumonia and headaches. Cranial CT showed an enlarged infundibulum of the pituitary gland. Results of CSF analysis were essentially normal, and direct smears were negative. He left the hospital against medical advice. Our study indicates that the finding of MAI in the CSF in patients with AIDS is associated with an in-house mortality of 67% indicating a very poor prognosis.

Coccidial parasites of the genus Isospora cause intestinal disease in several mammalian host species. These protozoal parasites have asexual and sexual stages within intestinal cells of their hosts and produce an environmentally resistant cyst stage, the oocyst. Infections are acquired by the ingestion of infective (sporulated) oocysts in contaminated food or water. Some species of mammalian Isospora have evolved the ability to use paratenic (transport) hosts. In these cases, infections can be acquired by ingestion of an infected paratenic host. Human intestinal isosporiasis is caused by Isospora belli. Symptoms of I. belli infection in immunocompetent patients include diarrhea, steatorrhea, headache, fever, malaise, abdominal pain, vomiting, dehydration, and weight loss, blood is not usually present in the feces. The disease is often chronic, with parasites present in the feces or biopsy specimens for several months to years. Recurrences are common, Symptoms are more severe in AIDS patients, with the diarrhea being more watery. Extraintestinal stages of I. belli have been observed in AIDS patients but not immunocompetent patients. Treatment of I. belli infection with trimethoprim-sulfamethoxazole usually results in a rapid clinical response. Maintenance treatment with trimethoprim-sulfamethoxazole is needed because relapses often occur once treatment is stopped.
