A 7-year-old girl with incontinentia pigmenti and a history of multiple bacterial infections developed chronic meningitis with Actinomycosis odontolyticus, which was successfully treated with long-term penicillin administration. Although all tests of immunologic function were normal in this patient, her history of recurrent and unusual infections is consistent with previous suggestions of an undefined immunodeficiency state associated with incontinentia pigmenti.

Cerebral tuberculomas developed in two adult Asian immigrants during treatment for miliary tuberculosis and tuberculous meningitis. Both were infected by strains of Mycobacterium tuberculosis sensitive in vitro to all antituberculous drugs, and no evidence of immunodeficiency was detected. Focal neurological signs appeared and the lesions led to the death of one patient despite maximum treatment. The importance of systemic corticosteroids in controlling the raised intracranial pressure is discussed.

The common soil fungus, Fusarium, is rarely pathogenic in man but occasionally causes serious disease, particularly in immunocompromised hosts. A case is reported of Fusarium brain abscess and meningitis occurring in a patient with chronic infectious mononucleosis syndrome and immunodeficiency. The patient died despite aspiration of the abscess and treatment with amphotericin B. This case demonstrates the importance of identifying the offending pathological organism through abscess aspiration in immunocompromised patients.

Delayed hypersensitivity skin testing was performed in 129 critically ill patients. Six intradermal antigens were used: tuberculin, candidin, varidase, epidermophytin, trichophytin and CCB (a polyvalent microbial vaccine from the Pasteur Institute). The response was judged as positive when one test or more were positive. Patients were devided in four groups: group A (40 cases): non-infected patients, a priori without immunodeficiency; group B (14 cases); suspected of immunodeficiency (cancers, hemopathies, collagen diseases receiving corticosteroids); group C (24 cases): decompensated chronic respiratory insufficienceis; group D (50 cases): overwhelming sepsis (septicaemias, septic acute respiratory distress syndromes, thoracic empyemas, purulent meningitis, peritonitis, mediastinitis). A significant diminution of delayed hypersensitivity was observed in groups B, C and D. No relation was found between delayed hypertensitivity and prognosis in groups C and D.

Hyponatremia has been recognized as a complication in adults with acquired immunodeficiency syndrome (AIDS). We did a retrospective study evaluating the medical records of 86 children (age 4 months to 21 years) with human immunodeficiency virus (HIV-1) infection to determine the frequency and clinical associations of hyponatremia. Twenty-two children (26%) developed hyponatremia (serum sodium < 135 mEq/L; range 104 to 134 mEq/L; mean 130 mEq/L). Fourteen were male; 18 of the 22 patients were black and 4 were white. At the time of hyponatremia, the children frequently had comorbid associations, including 8 (35%) with AIDS encephalopathy; 3 (14%) with cardiomyopathy; 3 (14%) using diuretics; 1 (5%) using pentamidine; 3 (14%) with bacterial pneumonia; 2 (9%) requiring gastric lavage feedings; 2 (9%) with tuberculosis meningitis; 2 (9%) with gastroenteritis; 1 (5%) with infection caused by Mycobacterium avium-intracellulare; 1 (5%) each with brain tumor and tumor metastasis to brain. The cause of hyponatremia was attributed to syndrome of inappropriate antidiuretic hormone in 8 children; poor sodium intake and/or excessive diarrheal losses in 5; and the use of diuretics in 3 patients. Mild hyponatremia with no identifiable cause was found in 5 patients.

Infection with Cryptococcus neoformans occurs with increased frequency in patients with the human immunodeficiency virus (HIV). Despite the lungs being the portal of entry for the fungus the commonest presentation is with meningitis: Cryptococcal broncho pulmonary infection occurs less commonly. The chest radiographs of fourteen HIV positive patients with cryptococcal pneumonia were reviewed. The commonest radiographic abnormalities were interstitial infiltrates, (nine patients) and focal or widespread alveolar consolidation (seven patients). Ground glass shadowing, not previously described in cryptococcal pneumonia, occurred in six radiographs, miliary nodules in one, lymphadenopathy in four, and small pleural effusions in three. Two patients had a normal chest radiograph. In contrast to previous reports, we found alveolar consolidation and ground glass shadowing to be common and nodules and cavitation to be rare. Cryptococcal pneumonia should be considered in the differential diagnosis of Pneumocystis carinii pneumonia, bacterial pneumonia and miliary tuberculosis in HIV positive patients.

Morphological imaging, based on the use of various techniques including ultrasound, X-ray computed tomography (CT), and magnetic resonance imaging (MRI), plays an important role in the characterization, diagnosis and follow-up of patients with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS). While the presence of thoracic infections, the most frequently observed illnesses in AIDS patients, can best be performed by using conventional chest films and CT, the assessment of cerebral involvement in AIDS patients--characterized by the presence of focal masses, demyelination, meningitis, and infarction--is best achieved using MRI. The work-up of patients with gastrointestinal symptoms should include the use of ultrasound for the evaluation of visceral involvement and lymphadenopathy, completed by CT to further characterize pathologic conditions in either the bowel or visceral organs. Ultrasound is the screening exam of choice in AIDS patients with suspected renal disease, but other methods may be necessary for the assessment of the complications due to pharmacological treatment. Musculoskeletal complications may require the combined use of all the above methods, since they may be caused by infections, tumors and rheumatologic illness. The use of the radiographic methods for the detection of the numerous forms of infections and malignancies in AIDS patients is described in detail for the various body districts.

There is little information available on invasive group B Streptococcus (GBS) infection in pediatric patients older than 3 months of age. Review of infection control records at LeBonheur Children's Medical Center from January 1, 1986, to June 30, 1993, identified 143 patients with a positive GBS culture from normally sterile body fluid. Medical records of 18 (13%) patients > 3 months old with their first GBS infection were reviewed. Age range was 15 weeks to 18 years (median age, 13 months). Ten were black and 11 were girls. Five infants had a history of premature birth and 2 infants were infected with human immunodeficiency virus. The serotype distribution of 12 available GBS isolates was 4 type III, 2 each type V and Ia and 1 each type Ia/c, Ib/c, II and II/c. Bacteremia without a focus (9 patients) was the most common clinical manifestation. All 4 type III isolates were associated with bacteremia. One infant with human immunodeficiency virus infection had sepsis and bullous desquamation; a toxin-producing type V strain was isolated from her blood. Two adolescents with ventriculoperitoneal shunts had meningitis, including one whose cerebrospinal fluid also grew a type V strain. Other clinical manifestations were septic arthritis, endocarditis (Ia, II/c), central venous catheter (Ia/c) and ventriculostomy infections.

The case of a 33-year-old patient with rapid onset of bilateral parotid gland and lymph node abscesses is described. The patient was positive for human immunodeficiency virus 1 and presented with a history of interstitial lymphocytic pneumonia and pneumococcal meningitis prior to admission. The patient received cotrimoxazole as primary prophylaxis against Pneumocystis carinii pneumonia. Fine needle aspiration from the abscesses yielded Streptococcus pneumoniae. Penicillin G treatment in combination with surgical drainage of the lesions led to healing with minimal residual lymph node enlargement. No relapse was noted until 12 months after presentation.

Rhodococcus species are increasingly being recognized as pathogens, especially in patients infected with the human immunodeficiency virus. Most cases of rhodococcus infection in these patients are due to Rhodococcus equi and involve the lungs. CNS infections due to Rhodococcus species are rare, and meningitis due to non-equi Rhodococcus has never been reported in a healthy host. We report a case of meningitis due to non-equi Rhodococcus in a previously healthy 24-year-old woman. We also review and summarize the reported cases of CNS infections caused by Rhodococcus species.
