RESUMO
An 86-year-old man was found with altered mental status, fever and aphasia. His physical exam revealed nuchal rigidity but no other meningeal signs. Because the patient's mental status was declining, he was intubated and placed in mechanical ventilation. His head CT scan was unremarkable, without evidence of mass effect. A lumbar puncture yielded cerebrospinal fluid that was remarkable for the presence of gram-positive cocci in pairs. His blood cultures showed gram-negative bacilli. Given the presence of these organisms, a polymicrobial infection was suspected. An abdomino pelvic CT scan showed a multi-septated abscess within the right hepatic lobe. CT-guided percutaneous drainage was performed and a specimen for culture obtained, which grew Klebsiella pneumoniae. After receiving intravenous antibiotics and supportive care, the patient showed clinical improvement. In this patient, there was a central nervous system infection secondary to bacteremia in the setting of an intrabdominal infection. The inquiring clinician should take note that whenever a polymicrobial infection is evidenced, more than one site of infection should be considered in the differential diagnosis.

An 80-year-old man experienced general weakness, myalgias, arthralgias, fever, chills, and diarrhea for one week. He had hypotension and tachycardia. He also had leukocytosis, thrombocytopenia, increased creatinine levels, elevated liver enzymes, elevated creatine phosphokinase (CPK) levels, and metabolic acidosis with hypoxemia, for which he was admitted to the Intensive Care Unit (ICU). His chest x-ray showed decreased lung volumes. Ceftriaxone and levofloxacin were empirically started to cover leptospirosis and community acquired pneumonia, respectively. The patient continued with clinical deterioration and the antibiotic therapy was changed to linezolid, cefepime, and doxycycline. He required endotracheal intubation and mechanical ventilation support due to progressive hypoxemic respiratory failure. A bronchoscopy showed no evidence of bacterial infectious process. The patient developed clinical improvement with successful extubation afterwards (4 days after initial intubation). He was later discharged home with physical therapies. A serum specimen was tested with real-time polymerase chain reaction (RT-PCR) technique, producing a positive result only for Zika virus. Confirmatory molecular diagnostic testing was performed at the Center for Disease Control (CDC).

Diagnosis of Sjogren syndrome should be based on consideration of the clinical presentation, a pulmonary function test, blood and rheumatology laboratory findings, radiographic imaging patterns, and biopsy results.
RESUMO
Although purulent pericarditis is rare, it is essential to recognize its clinical features due to the high mortality rate in patients with a missed diagnosis.
RESUMO
BACKGROUND: Endometrial cancer is the most common gynecologic malignancy in Puerto Rico and the United States (US). METHODS: We compare the age-specific and age-adjusted incidence and mortality rates and the survival of endometrial cancer in Puerto Rico with that of non-Hispanic whites (NHW), non-Hispanic blacks (NHB) and Hispanics in the US. Data from the Puerto Rico Central Cancer Registry and the Surveillance, Epidemiology, and End Results program were analyzed from 1992-2003. RESULTS: Age-standardized incidence rates of endometrial cancer increased significantly (p < 0.05) in Puerto Rico (APC = 2.8%) and among NHB (APC = 1.9%) and remained constant (p > 0.05) for NHW (APC = -0.1%) and Hispanics in the US (APC = 0.4%). Mortality trends remained constant in all racial/ethnic groups (p > 0.05). For 1999-2003, women in Puerto Rico had similar incidence of endometrial cancer as Hispanics (Standardized rate ratio [SRR] = 0.94, 95% CI = 0.87-1.01), although their risk was lower than that of NHW (SRR = 0.56, 95% CI = 0.53-0.59) and NHB (SRR = 0.91, 95% CI = 0.84-0.98). Meanwhile, women in Puerto Rico had 15% higher risk of death than Hispanic women (SRR = 1.15, 95% CI = 1.03-1.30) similar risk than NHW (SRR = 0.93, 95% CI = 0.83-1.03), and lower risk than NHB (SRR = 0.51, 95% CI = 0.46-0.57). Puerto Rico (63.1%) and NHB (56.8%) had a lower 5-year survival than NHW (78.4%) and Hispanics (79.5%). An age-adjusted Cox proportional hazards model showed that compared with women in Puerto Rico, Hispanic women in the United States had 37% lower mortality risk (HR = 0.63, 95% CI = 0.56-0.71) and NHW had 53% lower mortality risk (HR = 0.47, 95% CI = 0.43-0.52) after 5 years of diagnosis; NHB women had 22% higher mortality risk than women in Puerto Rico (HR = 1.22, 95% CI = 1.09-1.36). CONCLUSIONS: The lower burden of endometrial cancer in Puerto Rico suggests the presence of protective factors or lower exposure to risk factors in this population, although increases in incidence suggest changes in the occurrence of lifestyles and environmental risk factors. Meanwhile, the lower five-year survival from endometrial cancer among Puerto Ricans suggests a health disparity for this group in areas such as quality of care and/or differences in terms of stage at diagnosis and associated comorbidities. Assessment of disease risk factors and characteristics, and access and response to treatment is required to further understand these results.
