ABSTRACT
Bacillus Calmette-Guerin (BCG) intravesical instillation has been adopted in the treatment of patients with superficial bladder cancer. BCG-induced disseminated infection, though rare, has been associated with the histological finding of epithelioid granulomas in different organs, including the liver. We report the case of an adult patient with multi-organ failure, who developed sepsis, acute respiratory failure and acute hepatic failure with encephalopathy whose liver biopsy confirmed the presence of atypical, granulomatous-like lesions. Recovery was observed only after empirical therapy for Mycobacterium bovis with isoniazid, rifampicin, ethambutol and steroids was introduced. This case highlights the importance of a thorough patient assessment in order to exclude other more common causes of hepatic granulomas and to confirm diagnosis. Histological findings may be non-specific when the liver is involved in BCG-induced disseminated infection.
ABSTRACT
Recent advances in technology and novel pharmaceutical research findings have added new grounds in the fields of medical treatment and quality of life of patients diagnosed with pulmonary arterial hypertension (PAH). Collective assessment of new data is mandatory and useful for specialist medical doctors. This review aims to present the latest therapeutic developments of the last two years (2009-2010) in PAH. Moreover, recent patents (of the year 2010) regarding therapeutic novelties in PAH that expand treatment modalities, are hereby presented.

BACKGROUND: The high prevalence of bone metastases in stage IV non-small cell lung cancer (NSCLC) patients contributes substantially to the burden of the disease by resulting in significant skeletal morbidity. Ibandronate is a new generation of bisphosphonates (BPs) with demonstrated clinical benefit in breast and prostate cancer patients with bone metastases. PATIENTS AND METHODS: In 32 patients with newly diagnosed NSCLC and bone metastases, 4 mg of ibandronate were administered, as a rapid 20-minute intravenous infusion every 3-4 weeks. RESULTS: A total of 189 infusions were administered over a 24-month period, during which a statistically significant decrease in calcium serum levels (p=0.03) was observed. The serum levels of alkaline phosphatase (ALP) were also decreased, but not significantly. With regard to clinical efficacy, 24 of our patients stabilized or reduced their need for analgesic treatment. The reduced time of infusion (20 min vs. 2 h) did not correlate with any side-effects, including vital sign deterioration and renal dysfunction. CONCLUSION: The rapid infusion of ibandronate in lung cancer patients with bone metastases is a safe and convenient procedure that may be administered in a day-clinic setting.

BACKGROUND: The standard treatment for advanced non-small cell lung cancer (NSCLC) currently consists of platinum-based, combination chemotherapy of limited efficacy and possible toxicity. The bi-weekly administration of docetaxel and gemcitabine for advanced NSCLC was evaluated in a phase II study (objective response rate, median survival, median duration of response and safety). PATIENTS AND METHODS: A total of 170 cycles were administered to 31 patients with advanced NSCLC and a median age of 66 years (range 47-75 years). Patients received docetaxel 80 mg/m2 and gemcitabine 1000 mg/m2 on days 1 and 14 of a 28-day cycle. RESULTS: Sixteen patients achieved a PR (16/31, 55.2%), 3 patients had SD (3/31, 10.3%) and 10 (10/31, 34.5%) had PD. The median time to disease progression was 3 months (range 0-12 months) with a mean survival of 10 months (range 3-31 months). Haematological and non-haematological toxic effects were generally mild to moderate and manageable: Grade 3 neurotoxicity and allergy occurred in 2 patients (6.4%) and 1 patient (3.2%), respectively. Peripheral neuropathy, mostly grades 1 and 2, was reported in 24 patients (77.4%). CONCLUSION: The bi-weekly administration of a docetaxel/gemcitabine combination with G-CSF support constitutes a tolerable and convenient regimen for the treatment of advanced NSCLC, with efficacy similar to that reported in other regimens.
