Actinomyces meyeri is a rare pathogen and an infrequent cause of human actinomycosis. Less than ten cases were reported in the English-literature to date concerning A. meyeri empyema. We herein report a case to promote the awareness and adequate management of the disease.A 44-year-old immunocompetent male with known pulmonary disease was diagnosed with an A. meyeri empyema. He underwent chest tube drainage and a short-term treatment with clindamycin for 4 months.This is the first report of a patient with structural pulmonary disease with an A. meyeri empyema treated with 4-month of clindamycin and chest tube drainage. In comparison to previous reports, our case was diagnosed early, empyema was effectively drained with one chest tube and symptoms and radiological findings were rapidly improved. Short-term antibiotic treatment can be well succeeded if an early diagnosis is made, there is no evidence of dissemination and adequate management is promptly instituted.

ObjectivesDespite non‐small cell lung cancer (NSCLC) high prevalence and increasing incidence, evidence specific to the elderly and very elderly is sparse. To retrospectively compare characterization and approach of NSCLC patients (pts) aged 70‐79 and ≥80 years.MethodsWe performed a retrospective analysis of 297 adult NSCLC pts who registered and initiated NSCLC management in our Pulmonology Oncology Unit from January 2013 to December 2016 corresponding to 38.2% of all NSCLC patients (n = 778). Demographic data and lung cancer management were analysed.ResultsPts were categorized as elderly (n = 211, 71.0%) and very elderly (n = 86, 29.0%). Very elderly pts had worse Eastern Cooperative Oncology Group performance status (P = 0.047), higher Charlson age comorbidity index (P < 0.001) and the majority had stage IV cancer (66.3%, P = 0.04). The first management option in very elderly pts was chemotherapy (CTX) (30.2%, P = 0.37) and in elderly pts was multimodal therapy (30.3%, P ≤ 0.001). Support therapy and first‐line targeted (EGFR or ALK‐positive) were more common in the very elderly (23.6%, P = 0.01; 17.4% P = 0.002, respectively). Curative radiation or surgery rates did not differ between groups. Reasons for premature first‐line CTX stop, toxicity and hospitalization did not differ. Death rate (69.7% vs 63.5% for very elderly and elderly, respectively) and mean survival since diagnosis (11.5 vs 11.6 months for very elderly and elderly, respectively) did not differ.ConclusionsThere were significant differences in pts characteristics having the very elderly more multimorbidity and advanced state of disease. First management options were significantly different with respect to multimodal, targeted and support therapy.

In elderly patients, numerous factors subsidize the diagnostic challenge and high incidence of complications in this specific population, taking gangrenous cholecystitis as a critical example. The aim of this work is to report an unusual case of gangrenous choleystitis in an elderly diabetic women and its atypical clinical presentation. A 79-year-old female patient came to our observation; her medical history showed nausea and vomiting of about 2 hours which rapidly ended with symptomatic therapy, without recurrence, and a 3-week history of intermittent fever associated with productive cough. No abdominal discomfort was declared. Physical examination of the abdomen was negative. Laboratory analysis revealed leukocytosis with the remaining criteria within the normal range. After 2 days, she started with a mildabdominal pain in the epigastric region that rapidly progressed to the right upper quadrant, right flank and right iliac fossa, without nausea, vomiting or fever. Abdominal computer tomography findings revealed thickness of the gall-bladder and important densification of the vascular bed. Acute cholecystitis was diagnosed. The patient was then submitted to a laparoscopic cholecystectomy under general anaesthesia with findings suggestive of gangrenous acute cholecystitis confirmed by histologic examination of the specimen. Delays in diagnosing acute cholecystitis in specific populations, such as elderly diabetics, result in a higher prevalence of morbidity and mortality due to potentially serious complications as gangrenous cholecystitis. Consequently, the diagnosis should be measured and investigated promptly in order to prevent poor outcomes.

Background: Few data is available in low-burden TB-HIV countries on TB treatment outcomes. We evaluated TB patients (pts) characteristics by HIV status and compared treatment outcomes in relation to HIV status, CD4 count and antiretroviral therapy (ART). Methods: We performed a retrospective analysis of 447 adult TB pts who registered and initiated treatment in our center from 2014 to 2015. Results: Pts were categorized as HIV-negative (n = 399, 89.3%), HIV-positive on ART (n = 42, 9.4%) and HIV-positive not on ART (n = 6, 1.3%). The proportion of pts with extended TB therapy was higher among HIV-positive pts (p = 0.03). Increased age was associated with higher death rates regarding treatment success (OR 1.08; 95% CI 1.01-1.17, p = 0.03). Statistically significant higher mortality was found among HIV-positive pts on ART (OR 9.93; 95% CI 1.36-72.37, p = 0.03) and HIV-positive pts not on ART (OR 397.00; 95% CI 44.27 to 3559.91, p ≤ 0.0001) compared to HIV-negative pts. When multivariate analyses were restricted to HIV-positive pts, being not on ART was associated with higher mortality (OR 40.0; 95% CI 4.37-365.78, p = 0.001). Conclusions: There was significant difference in death rates between HIV-positive and HIV-negative TB pts. HIV-positive pts not on ART had a significantly higher mortality.

Pulmonary mucormycosis is an emergent and life-threatening invasive fungal infection underdiagnosed by clinicians due to unspecific clinical picture and lack of awareness. Although the acknowledgment of risk factors, clinical and radiological findings may increase early recognition, the definite diagnosis is challenging to establish and the ideal treatment has never been delineated. The authors describe a rare case of pulmonary mucormycosis that was successfully treated with dual antifungal treatment and surgery in a patient with uncontrolled diabetes. When last evaluated, he was asymptomatic with no evidence of relapse. To our knowledge this is a rare report of a successfully treated diabetic patient with pulmonary mucormycosis with LAmB , triazole posaconazole and surgery with no evidence of recurrence. We highlight the importance of clinicians' awareness to early diagnosis, combined antifungal treatment and adjuvant surgery as the greatest chance of cure of a rapidly progressive disease with high mortality and morbidity.

The diagnosis and management of blood culture-negative endocarditis constitute a real clinical challenge and a systemic approach is necessary for a successful outcome. The authors report a case of a female patient aged 26, with previous clinical history of valve disease and heart failure NYHA class II, with decompensation of co-morbidities associated with fever, productive cough, nonselective anorexia and unquantified weight loss with one month of evolution with negative blood cultures. Transesophageal echocardiography revealed the presence of severe pulmonary hypertension and mitral valve vegetations in the context of positive serology for Q fever. Herein, the authors report a case of blood culture-negative endocarditis and present a brief review on the management of this medical condition. We highlighted the diagnostic difficulties of blood culturenegative endocarditis and subacute clinical presentation, which sometimes present with fever of unknown origin and complaints of deterioration of cardiac function, thus creating a challenging differential diagnosis.
