Five cases of disseminated histoplasmosis complicating renal transplantation are reported. Nine previously reported cases from the literature are reviewed. In this setting disseminated histoplasmosis usually presents as a nonspecific systemic febrile illness that may be fulminant or more subacute. Five of 14 patients presented with skin lesions; only one patient presented with primary pulmonary symptoms of cough and dyspnea. Three of our patients and three others previously reported on survived the infection and maintained good function in the transplanted kidney despite prolonged therapy with amphotericin B. Immunosuppression was the only predisposing factor that could be identified with certainty in the five patients reported on herein. However, in two of the five patients the onset of disseminated histoplasmosis coincided with a well documented cytomegalovirus infection; the viral infection may have been a factor predisposing to infection in these two cases.

Broncholithiasis, associated most frequently with tuberculosis and histoplasmosis, usually presents with acute onset of cough and hemoptysis. Visible stones are coughed up in fewer cases than was previously believed. The disease may be accompanied by obstructive symptoms, bronchiectasis, and occasional fistula formation into either the esophagus or the aorta. The prognosis of these patients is generally excellent; however, a significant number require surgery because of persistent symptoms or a complication of the disease.

In this retrospective study of 115 cases of histoplasmids, there were 66 male and 49 female patients ranging in age from 2 months to 79 years. The most common presenting symptoms were cough, chest pain, wheezing, weight loss, hemoptysis, and shortness of breath. Thirty-five patients (30%) were asymptomatic. Two patients had manifestations of obstruction of the superior vena cava. Radiologic findings simulated carcinoma, tuberculosis, pneumonia, and viral infections. Sixty-five patients had various operative proceudres, such as lung biopsy, wedge resection, lobectomy, pneumonectomy, resection of lymph node, and bypass of superior vena cava, for diagnosis and treatment. There were two deaths and two postoperative complications. A total of 15 patients received intravenous amphotericin B. Four patients with pneumonic infiltrates developed disseminated histoplasmosis.

Approximately 14 days after exploring a limestone cave in northcentral Florida in February 1973, an 18-year-old female developed a respiratory illness with pronounced shortness of breath and cyanosis. The following day, an 18-year-old male presented to the hospital with similar complaints. The association of illness with their recent caving experience prompted further epidemiologic investigation. Twenty-nine members of a church-sponsored youth group explored the implicated cave. Twenty-three of them later became ill with complaints of cough, afternoon fever and sweats, chest discomfort, and dyspnea on exertion. Histoplasmin skin tests were positive in 18 of 24 individuals tested. Serum for complement fixation (CF) was positive in 12 of 26. Testing of area residents revealed a low incidence of skin test and CF positivity (7% and 0%, respectively). That spelunkers are at risk of acquiring pulmonary histoplasmosis has been noted previously; in Florida this has been related to the exploration of caves infested with bats. This is the largest reported outbreak of acute pulmonary histoplasmosis that has been associated with spelunking and further points out that only those individuals who enter the cave are at risk of acquiring the disease, and not those who reside in the surrounding area.

Disseminated histoplasmosis (DH) is recognized as an opportunistic infection in patients with the human immunodeficiency virus (HIV), especially in regions where histoplasmosis is endemic. At the Kansas University Medical Center 148 patients were hospitalized with the diagnosis of AIDS from December 1983 to March 1991; 23 of these patients (16%) had disseminated histoplasmosis. The charts of these 23 patients were reviewed. Clinical signs and symptoms included fever (91%), cough (65%), and weight loss (48%). Splenomegaly, hepatomegaly, or lymphadenopathy was present in 52% of all patients. Anemia (39%), leukopenia (65%), and thrombocytopenia (52%) were common, and 22% had pancytopenia. Diagnosis was made by peripheral smear examinations (organisms visualized on 7 of 22 smears [32%]), blood cultures (positive for H capsulatum in 16 of 20 patients, [80%]), bone marrow cultures (positive in 14 of 15 patients, [93%]), and bone marrow aspirate and biopsy examinations (organisms seen on 18 of 21 stains, [86%]). The combination of these four tests revealed the diagnosis of DH in 23 of 23 patients (100%). Induction and maintenance amphotericin B therapy was given to all but 2 patients, and currently 8 of the 23 are alive. DH is a common opportunistic infection in AIDS patients from regions endemic for histoplasmosis. When DH is suspected, a peripheral smear examination, blood cultures, bone marrow cultures and bone marrow aspirate and biopsy should be done to make the diagnosis, since suppression of the disease is possible with appropriate therapy.

The authors report a case of benign multinodular pulmonary histoplasmosis, occurring in a 65 year old woman coming back from Guatemala. The disease presented with both fever and cough. The diagnosis was made on a lung biopsy (by thoracotomy) that showed granulomas with giant cells, lymphocytes and central necrosis, and histoplasma capsulatum yeasts on Gomori Grocott coloration. The authors recall the main radiological forms of the disease, and the difficulties of the diagnosis. When not disseminated, histoplasmosis usually has a good prognosis and does not require any treatment.

A 15-months-old boy underwent the intra-cardiac repair with a glutaraldehyde-preserved equine pericardium for total anomalous pulmonary venous connection (Darling's type IIb). Because of rapidly progressive dyspnea, tachycardia and respiratory acidosis, he required emergent reoperation at 234 postoperative days. The pseudointima was thickened heavily and detached from glutaraldehyde-preserved equine pericardium. New channel was created with a piece of EPTFE sheet to prevent obstruction of pulmonary venous flow. However, about four months after second surgery, cough and tachycardia progressed again remarkably. Intra-atrial channel was obstructed between EPTFE sheet and the partition from pulmonary venous orifice to the atrial septal defect in the third operation. The intra-atrial channel was enlarged by cut-back method using EPTFE sheet again. His postoperative hemodynamics were satisfactory

Captive coyotes (Canis latrans) were inoculated intragastrically (1 coyote), and intratracheally (6 coyotes) with Histoplasma capsulatum to simulate natural routes of exposure. In addition, the infectious organism was inoculated IV into another coyote and into a dog (C familiaris) to simulate hematogenous dissemination of H capsulatum. Isolation of the pathogen from various tissue specimens, using direct plating and mouse inoculation methods, provided mycologic evidence of infection. The presence of anti-Histoplasma serum antibodies also was monitored. Of the 6 coyotes challenged intratracheally, one developed a benign pulmonary form of histoplasmosis. This coyote developed a transient cough, and intracellular yeasts typical of H capsulatum were observed microscopically in pulmonary tissue specimens. The pathogen was isolated from specimens of pulmonary tissue and associated lymph nodes. The coyote that was fed Histoplasma-infected mice (intragastric challenge) did not develop clinical disease. The coyote and the dog inoculated IV developed a multifocal, nonsuppurative infection, without clinical evidence of histoplasmosis. Pathologic findings in the coyote and dog were similar; both animals had splenitis, lymphadenitis, and petechiation of the lungs. The liver and spleen were considered the primary extrapulmonary target organs on the basis of mycologic and histologic findings.

Acquired immunodeficiency syndrome (AIDS) is reviewed for dental practitioners, with an emphasis on oral findings; the clinical course, diagnosis, reporting, treatment, prognosis, transmission, and epidemiology are also covered. HIV infection has an incubation period that may be associated with glandular fever, a prodrome called AIDS-Related Complex (ARC) characterized by lymphadenopathy, low fever, weight loss, night sweats, diarrhea, oral candidosis, nonproductive cough and recurrent infections. AIDS is characterized by opportunistic infections. Over 50% present with pneumocystis carinii pneumonia, 21% with Kaposi's sarcoma, and 6% have both. The AIDS virus causes direct neurological symptoms in some cases. Oral candidosis (thrush) in a young male without a local cause such as xerostomia or immune suppression is strongly suggestive of AIDS. Other oral manifestations are severe herpes simplex, varicella-zoster, Epstein-Barr virus, cytomegalovirus, venereal warts, aphthous ulceration, mycobacterial oral ulcers, oral histoplasmosis, sinusitis and osteomyelitis of the jaw. Hairy leukoplakia, usually seen on the lateral border of the tongue, is probably caused by Epstein-Barr virus. Kaposi's sarcoma, an endothelial cell tumor, is characteristic of AIDS, and in 50% of patients is oral or perioral. Cervical lymph node enlargement will be seen in those with ARC as well as AIDS. No guidelines have been issued by the Department of Health and Social Security for dental surgeons in the UK for reporting AIDS cases. Although HIV virions have been isolated from saliva, there are no known incidents of transmission via saliva. HIV is less likely to be transmitted by needle stick injuries than, for example hepatitis B (25% risk), especially if the blood is from a carrier rather than a full blown AIDS case.

Three male college students from Florida developed acute onsets of fever, chills, shortness of breath, and cough within one day of each other, and all were eventually hospitalized for four to 29 days. All chest x-ray films showed diffuse reticulonodularities in both lung fields. Laboratory studies confirmed the diagnosis of histoplasmosis. The three students had been 'spelunking' (cave exploring) 6 to 7 days before their onset of symptoms. One of four soil samples collected in the caves was positive for Histoplasma capsulatum by the indirect mouse inoculation procedure. Of three investigators who entered the implicated caves, two developed acute febrile illness within 15-21 days. One investigator was hospitalized for 18 days with a confirmed diagnosis of histoplasmosis. Investigation identified an additional case (the person had entered the caves 6 months before this episode), but was not reported to health authorities. Spelunkers should be aware of the potential risk of histoplasmosis and how to avoid infection. Physicians should be cognizant of cave-associated histoplasmosis, inquire about spelunking in persons who develop febrile respiratory illnesses with diffuse nodularities on chest x-ray films, and report such cases to their health department. A review of 42 reported outbreaks of cave-associated histoplasmosis and the approach to environmental control of infected caves are included.
