A 31-year-old man was hospitalized for evaluation of chronic diarrhea accompanied by profound dehydration, abdominal pain, nausea, vomiting, and low-grade fever. He had been identified as hepatitis B surface antigen-positive in 1983 and HIV antibody-positive two years later. In 1987, after a diagnosis of Pneumocystis carinii pneumonia, he had been placed on zidovudine and prophylactic pentamidine. Subsequently, thrush developed, which was treated with nystatin. The patient's gastrointestinal symptoms were of about six months' duration and originally had responded fairly well to diphenoxylate. More recently, however, he had been losing weight steadily and had required emergency room rehydration on two occasions. A search for stool ova and parasites and routine enteric pathogens, conducted by the outpatient department, had revealed Cryptosporidium cysts.

A 38-year-old hemophiliac, who had been infected with HIV by the administration of blood products and had been diagnosed as AIDS by the onset of Pneumocystis carinii pneumonia, was admitted to our hospital with the complaints of headache and vomiting. After he was diagnosed as cryptococcal meningitis using the microscopy, cryptococcal antigen detection and culture of cerebrospinal fluid, treatment with amphotericin-B and fluconazole was started. As there was no clinical improvement, spinal drainage was performed and acetazolamide administered in order to reduce the intracranial pressure. Treatment was changed from AMPH-B and FLCZ to a combined therapy of AMPH-B and itraconazole. As his clinical features showed improvement, he was discharged home on a maintenance dose of ITCZ and acetazolamide after having been hospitalized for three months. This case-report may be of use in the management of cryptococcal meningitis in patients with AIDS.

Pneumonia due to Pneumocystis carinii is an infrequent complication following autologous stem cell transplantation (ASCT) which is associated with a high mortality. Although administration of trimethoprim/sulfa- methoxazole (TMP/SMX) is an effective prophylactic strategy for Pneumocystis carinii pneumonia (PCP), treatment-associated toxicity frequently results in discontinuation of therapy. We have conducted a prospective randomized trial comparing atovaquone, a new anti-Pneumocystis agent, with TMP/SMX for PCP prophylaxis following autologous peripheral blood stem cell (PBSC) transplantation. Thirty-nine patients were studied. Twenty patients received atovaquone suspension and 19 patients received TMP/SMX. The median ages were 44 (range 20-68) and 47 (range 32-63) years, respectively. A similar number of patients with solid tumors (14 vs 15) and hematologic malignancies (five vs five) were treated in each group. Either TMP/SMX (160/800 mg) or atovaquone (1500 mg) was administered daily from transplant day -5 until day -1, discontinued from day 0 to engraftment, then resumed 3 days per week until day +100 post-transplant. The median time to engraftment (ANC >0.5 x 109/l) was similar in both groups. Eighty percent of the patients randomized to atovaquone prophylaxis completed the study. Four atovaquone-treated patients were removed from study; two patients (10%) did not receive a transplant and two patients (10%) were removed due to a protocol violation. None of the 16 patients treated with atovaquone experienced treatment-associated adverse effects. Of the 19 patients randomized to receive TMP/SMX, 55% completed the study. Nine TMP/SMX-treated patients were removed from the study; one patient (5%) did not receive a transplant and eight patients (40%) were removed due to drug intolerance (P < 0.003). The rate of intolerance to TMP/SMX led to the early discontinuation of this randomized trial. Intolerance of TMP/SMX included elevated transaminase levels (n = 1), nausea or vomiting (n = 3), thrombocytopenia (n = 2) and neutropenia (n = 2). All episodes of TMP/SMP intolerance occurred following transplantation after a median duration of 17.5 (range 2-48) days and a median of 7 (range 1-20) doses. Resolution of adverse side-effects occurred in all eight patients within a median of 7 (range 2-20) days following discontinuation of therapy. Neither PCP nor bacterial infections were identified in any of the patients treated. This prospective randomized study demonstrated that atovaquone is well-tolerated for anti-Pneumocystis prophylaxis in autologous PBSC transplant patients intolerant of TMP/SMX.

A 56-year-old, obese woman who had been sexually inactive for 10 years presented at the hospital with high fevers, decreased appetite, nausea, vomiting, and weight loss. Following many diagnostic tests that revealed little, it was found that her estranged husband was being treated for Pneumocystis carinii pneumonia (PCP). The woman was tested for HIV and found to be positive. This is an example of the Centers for Disease Control and Prevention's (CDC) indication that 10 percent of reported AIDS cases occur in people over age 50, that diagnosis is often delayed in older age groups, and that anyone suffering from fever of an unknown origin should be tested for HIV. In such situations it is suggested that general practice include seeking behavioral information and offering HIV testing and counseling.

Aspiration of oro-pharyngeal secretions and gastric content is the most frequent cause of formation of primary lung abscess. A compromised mental status (e.g. alcoholism, sedatives, stroke) and esophageal dysfunction (e.g. herniation, vomiting) are important risk factors. Aspiration pneumonia presents as a subacute disease and is usually not distinguishable from other causes of pneumonia, until typical radiological signs of cavitation and putrid sputum appear 8 to 14 days after the initial event of aspiration. Anaerobic bacteria play a pivotal role in an almost exclusively mixed spectrum of causative organisms. Aerobic pathogens are also frequently isolated, but whether they are an active part of infection or merely represent colonizers remains unclear in many instances. Differential diagnosis includes bronchial neoplasms, either as necrotizing carcinoma or as the cause of poststenotic cavernous pneumonia, other infectious diseases like tuberculosis, Pneumocystis carinii pneumonia or endocarditis with septic metastases, and lung artery embolism or vasculitis (M. Wegener). Fiberoptic bronchoscopy is extremely helpful in determining cause and etiology of the disease and should be carried out in all patients presenting with cavernous lung lesions. Bacteriological sampling should be performed using protected specimen brushing (PSB) technique. Broncho-alveolar lavage might serve as a less expensive but also less sensitive alternative measure. Since anaerobic bacteria resemble ubiquitous commensals of the oral cavity, sputum is of no use in anaerobic culture. Principal therapeutic strategy is antibiotic therapy for an extended period, usually four weeks to four months, unless radiologic changes and as well laboratory as clinical indicators of infection are completely resolved. Clindamycin, optionally supplemented with a second or third generation cephalosporin and Ampicillin/Sulbactam proved equally effective in treating aspiration pneumonia and primary lung abscess. The role of Moxifloxacin and other new flouroquinolones with their favorable pharmacodynamics is currently evaluated. Provided that antibiotics are prescribed for a sufficient period of time and patients' compliance is ensured, surgical procedures are limited to a negligible number of complications, e.g. recurrent severe hemoptysis, empyema or broncho-pleural fistula.

On March 15, 2005, the U.S. Food and Drug Administration approved temozolomide (Temodar capsules, Schering-Plough Research Institute) for the treatment of adult patients with newly diagnosed glioblastoma multiforme concomitantly with radiotherapy and then as maintenance treatment. Five hundred seventy-three glioblastoma multiforme patients were randomized to receive either temozolomide + radiotherapy (n = 287) or radiotherapy alone (n = 286). Patients in the temozolomide + radiotherapy arm received concomitant temozolomide (75 mg/m2) once daily for the duration of radiation therapy (42-49 days). This was followed, 4 weeks later, by six cycles of temozolomide, 150 or 200 mg/m2 daily for 5 days, every 4 weeks. Patients in the control arm received radiotherapy only. In both arms, radiotherapy was delivered as 60 Gy/30 fractions to the tumor site with a 2 to 3 cm margin. Pneumocystis carinii pneumonia prophylaxis was required during temozolomide + radiotherapy treatment and was continued until recovery of lymphocytopenia (Common Toxicity Criteria grade <1). At disease progression, temozolomide salvage treatment was given to 161 of 282 patients (57%) in the radiotherapy alone arm, and to 62 of 277 patients (22%) in the temozolomide + radiotherapy arm. Patients receiving concomitant and maintenance temozolomide + radiotherapy had significantly improved overall survival. The hazard ratio was 0.63 (95% confidence interval, 0.52-0.75; log-rank, P < 0.0001). Median survival was 14.6 months (temozolomide + radiotherapy) versus 12.1 months (radiotherapy alone). Adverse events during temozolomide treatment included thrombocytopenia, nausea, vomiting, anorexia, constipation, alopecia, headache, fatigue, and convulsions.

A retrospective review was performed of patients diagnosed with Pneumocystis carinii pneumonia (PCP) from 1994 to 2003 at the Prince of Wales Hospital in Hong Kong. Eighteen patients were identified. Six (33.3%) were co-infected with human immunodeficiency virus (HIV). The remaining 12 non-HIV-infected patients had underlying diseases: three post-renal transplant recipients, three with haematological malignancies, two with auto-immune diseases, two with renal diseases, one with hepatocellular carcinoma and one with congenital cytomegalovirus disease. Cytomegalovirus co-infection was observed in four patients. All patients received cotrimoxazole therapy, with intolerance observed in four of them, including one with glucose-6-phosphate dehydrogenase deficiency, two with repeated vomiting and one with renal impairment. Overall crude mortality was 33.3%. The results suggested that, apart from being a common infection for patients with HIV infection, PCP can occur during the course of many immunosuppressive diseases and therapies. The mortality of PCP was high despite appropriate treatment. Chemoprophylaxis should be considered in populations at risk.

Fibromatosis, or extra-abdominal desmoid tumor, is a benign disease which often has an aggressive clinical course that can be difficult to treat. We performed a retrospective review of 16 patients (12 females and four males) with a mean age of 34.2 years treated with methotrexate and vinblastine for newly diagnosed or recurrent extra-abdominal desmoid tumor. The mean age of our patient cohort was 34.2 years (range 11-70), and the mean tumor size was 11.5 cm (range 2.5-21.2 cm). The mean duration of therapy was 12 months with an average follow-up of 43 months (range 1-149 months). Fourteen of 16 patients demonstrated a clinical response to treatment. Eight of 14 patients demonstrated a radiologic decrease in tumor size. Only one patient progressed on therapy. Six patients developed recurrent symptoms after discontinuation of treatment. Chemotherapy-related symptoms including neutropenia, nausea, and vomiting were common and observed in most patients, however these side effects were mild and transient. Five patients developed peripheral neuropathy that prompted a change from vinblastine to vinorelbine during treatment. One potentially life-threatening complication (pneumocystis pneumonia) occurred which was diagnosed early and successfully treated. The use of methotrexate and vinblastine/vinorelbine in the management of fibromatosis appears to be an effective treatment with minimal treatment-related side effects.
