A patient developed oliguria, peripheral edema, and dyspnea 5 days after mitral valve replacement. Chest roentgenogram and echocardiogram suggested pericardial effusion. Although pulsus paradoxus was absent, cardiac tamponade was suspected and subsequently confirmed during pericardiocentesis. Before pericardiocentesis right and left ventricular diastolic pressures were equal, as well as intrapericardial and right atrial pressures. The left ventricular cavity was reduced in size on the echocardiogram. Interventricular septal motion was normal. Pericardiocentesis normalized the hemodynamics and allowed the left ventricle to reexpand. Certain atypical features are tentatively explained as the combined effect of constrictive and effusive components caused by intrapericardial hemorrhage.

Tumor lysis syndrome, which develops after effective therapy of malignant conditions and leads to hyperuricemia, hyperkaliemia, hyperphosphatemia, hypocalcemia and elevated lactate dehydrogenase, is uncommon in solid tumors. In breast carcinoma it can be associated with tamoxifen flare, i.e. a transient increase in symptoms, mainly bone pain, observed shortly after the start of tamoxifen therapy. We report the case of a patient with advanced breast carcinoma involving the pleural space, unresponsive to combined chemotherapy, who experienced rapid worsening after the initiation of letrozole. Her symptoms included shock, bilateral pleural effusion, cardiac tamponade and oliguria. Laboratory parameters disclosed elevated transaminase, lactate dehydrogenase, uric acid and D-dimer blood levels. The patient was in critical condition for nearly 2 weeks. She improved progressively and has remained well and in complete remission for 20 months. This clinical picture suggests increased damage to the pleura (and probably the pericardium) and rapid leakage of tumor products, following the start of endocrine therapy. Letrozole is a non-steroidal aromatase inhibitor which is used in advanced breast cancer, resistant to first-line endocrine/chemotherapeutic treatment. Our review of the literature did not disclose any other descriptions of flare and tumor lysis syndrome after aromatase inhibitor therapy. Moreover, this case was characterized by atypical and complex clinical features. The aim of this presentation is to point out the practical significance, in neoplastic patients, of the differential diagnosis between symptoms due to tumor progression and those associated with anomalous reactions to therapy.

We evaluated the recovery of cardiovascular function after transient cardiogenic shock. Cardiac tamponade was performed for 1 h and post-shock data were collected in 5 domestic large white female pigs (43 +/- 5 kg) for 6 h. The control group (N = 5) was observed for 6 h after 1 h of resting. During 1 h of cardiac tamponade, experimental animals evolved a low perfusion status with a higher lactate level (8.0 +/- 2.2 vs 1.9 +/- 0.9 mEq/L), lower standard base excess (-7.3 +/- 3.3 vs 2.0 +/- 0.9 mEq/L), lower urinary output (0.9 +/- 0.9 vs 3.0 +/- 1.4 mL x kg(-1) x h(-1)), lower mixed venous saturation, higher ileum partial pressure of CO2-end tidal CO2 (EtCO2) gap and a lower cardiac index than the control group. Throughout the 6-h recovery phase after cardiac tamponade, tamponade animals developed significant tachycardia with preserved cardiac index, resulting in a lower left ventricular stroke work, suggesting possible myocardial dysfunction. Vascular dysfunction was present with persistent systemic hypotension as well as persistent pulmonary hypertension. In contrast, oliguria, hyperlactatemia and metabolic acidosis were corrected by the 6th hour. The inflammatory characteristics were an elevated core temperature and increased plasma levels of interleukin-6 in the tamponade group compared to the control group. We conclude that cardiovascular recovery after a transient and severe low flow systemic state was incomplete. Vascular dysfunction persisted up to 6 h after release of tamponade. These inflammatory characteristics may also indicate that inflammatory activation is a possible pathway involved in the pathogenesis of cardiogenic shock.

We describe the case of a 32-year-old woman with a history of cardiac surgery two weeks previously who presented with an upper gastrointestinal bleed. She also had symptoms of syncope and abdominal pain, as well as elevated liver enzymes. She had cool, clammy extremities, bilateral lower extremity edema, and oliguria. An echocardiogram was obtained, which revealed a large posterior pericardial effusion with evidence of tamponade physiology, and an emergent pericardiocentesis was performed with insertion of a drainage catheter, which drained bloody fluid, with subsequent hemodynamic improvement. <Learning objective: Cardiac tamponade symptomatology may vary tremendously from patient to patient, and therefore requires a high clinical suspicion in those presenting with evidence of cardiogenic shock. Understanding signs, symptoms, and physiology of cardiac tamponade is essential for diagnosis of delayed post-operative cardiac tamponade, occurring >7 days after open-heart surgery, a challenging diagnosis given its vague symptoms and signs not classically associated with the condition.>.

In recent decades, emerging fungal infections have changed the clinical mycology scenario as a consequence of the advances in medical diagnostics and therapeutic procedures, long hospitalization times, and the growing number of individuals with debilitating chronic diseases and impaired immune systems. This report presents a 19 months old Brazilian female patient who developed a severe fungal sepsis by an uncommon yeast. She was admitted at the intensive care unit with severe pneumonia, bronchopulmonary dysplasia, and weight-for-age z score of less than -2. She remained more than 30 days in the intensive care unit where she had a femoral venous catheter placement, enteral nutrition, broad-spectrum antibiotic therapy, and prophylaxis with fluconazole. Moreover, pericardiocentesis was performed due to cardiac tamponade. She had a previous history of prematurity, cardiac surgery due to patent ductus arteriosus, and a long period of hospital stay. Despite the antifungal prophylaxis, two yeast isolates were recovered from blood and then identified by classical mycological methods and internal transcribed spacer (ITS) sequencing as Wickerhamomyces anomalus. Both isolates exhibited susceptibility to amphotericin B, ketoconazole, itraconazole, voriconazole, and fluconazole. Her clinical state worsened, presenting anasarca, epistaxis, and hemorrhagic suffusions in the mouth, sclera, oliguria, and bradycardia. Two days after the first positive culture, she presented a gradual reduction of the white blood cells count, with severe leukopenia and neutropenia. She died five days after.
