Safety and efficacy of zoledronic acid rapid infusion in lung cancer patients with bone metastases: a single institution experience.

Zoledronic acid (Zometa, Novartis, Basel, Switzerland) is a new generation of bisphosphonates (BPs) with demonstrated clinical benefit in breast and prostate cancer patients with bone metastases. The safety and efficacy of intravenous zoledronic acid in lung cancer patients was assessed. In 86 patients with newly diagnosed non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) and bone metastases, 4 mg of zoledronic acid was administered with rapid 15-minute intravenous infusion every 3-4 weeks.

Severe community-acquired pneumonia with acute hypoxemic respiratory failure due to primary infection with Chlamydia pneumoniae in a previously healthy adult.

Community-acquired pneumonia due to Chlamydia pneumoniae is associated with a benign clinical course. Severe, life-threatening pneumonia is rare and occurs only in immunocompromised hosts. We report a case of severe pneumonia complicated by acute hypoxemic respiratory failure due to primary infection with C.

Pulmonary tuberculosis and its therapy do not significantly affect thyroid function tests.

Basal thyrotropin, total thyroxine, total tri-iodothyronine and free tri-iodothyronine were measured in 30 HIV-negative patients with focal pulmonary tuberculosis upon starting and after one and two weeks of isoniazid, rifampicin and pyrazinamide therapy. Rapid and statistically significant elevations in free tri-iodothyronine and total tri-iodothyronine were noted after the first and second week of treatment respectively. For most patients, however, hormone levels remained within normal limits throughout the study.
