RESUMEN
BACKGROUND Acute bacterial pericarditis is rare, and the incidence numbers have been declining in the modern antibiotic era. Purulent bacterial pericarditis is a fatal disease in which mortality rates can reach 100% if left untreated. CASE REPORT We present a case of primary purulent bacterial pericarditis with polymicrobial growth including Micromonas micro, Prevotella intermedia and Fusobacterium species, all of which are anaerobic flora of the oral cavity. Constant re-accumulation of the purulent pericardial effusion led the patient to have recurrent echocardiographic and clinical cardiac tamponade requiring recurrent pericardiocentesis' and eventually a pericardial window. CONCLUSIONS Although rare, bacterial pericarditis has been noted to lead to clinical and echocardiographic tamponade. Early diagnosis and treatment are necessary for improving clinical outcomes. It is important to have a suspicion for purulent pericarditis, due to its high level of mortality, in patients who present with non-specific symptoms and pleuritic chest pain.

CONTEXT: Somatostatin (SST) receptors (SSTRs) are expressed in a number of tissues, including the adrenal cortex, but their role in cortisol secretion has not been well characterized. OBJECTIVES: The objective of the study was to investigate the expression of SSTRs in the adrenal cortex and cultured adrenocortical cells from primary pigmented nodular adrenocortical disease (PPNAD) tissues and to test the effect of a single injection of 100 µg of the SST analog octreotide on cortisol secretion in patients with PPNAD. SETTING AND DESIGN: The study was conducted at an academic research laboratory and clinical research center. Expression of SSTRs was examined in 26 PPNAD tissues and the immortalized PPNAD cell line CAR47. Ten subjects with PPNAD underwent a randomized, single-blind, crossover study of their cortisol secretion every 30 minutes over 12 hours (6:00 pm to 6:00 am) before and after the midnight administration of octreotide 100 µg sc. METHODS: SSTRs expression was investigated by quantitative PCR and immunohistochemistry. The CAR47 and primary cell lines were studied in vitro. The data of the 10 patients were analyzed before and after the administration of octreotide. RESULTS: All SSTRs, especially SSTR1-3, were expressed in PPNAD at significantly higher levels than in normal adrenal. SST was found to differentially regulate expression of its own receptors in the CAR47 cell line. However, the administration of octreotide to patients with PPNAD did not significantly affect cortisol secretion. CONCLUSIONS: SSTRs are overexpressed in PPNAD tissues in comparison with normal adrenal cortex. Octreotide did not exert any significant effect on cortisol secretion in a short clinical pilot study in a small number of patients with PPNAD, but long-acting SST analogs targeting multiple SSTRs may be worth investigating in this condition.
