Primary spontaneous pneumothorax during pregnancy: A case report and review of the literature.

Spontaneous pneumothorax in pregnancy is an extremely rare cause of dyspnea with less than 100 cases reported in the literature. A 28-year-old primigravida at 39+4 weeks of gestation presented to the emergency department with sudden onset of dyspnea and pleuritic chest pain. A chest radiograph revealed a large, left-sided pneumothorax with a collapsed lung. A chest tube was placed with incomplete re-expansion of the lung. A cesarean section under epidural anesthesia was performed for suspected macrosomia. The postpartum was uneventful. Despite its rarity, spontaneous pneumothorax should be excluded in every pregnant woman presenting with sudden onset of dyspnea and chest pain. A heightened index of suspicion is essential for prompt management of this condition, avoiding adverse fetal and maternal outcomes. For a correct diagnosis and management, more solid recommendations and a multidisciplinary approach are needed.

Lower urinary tract symptoms in enuretic and nonenuretic children.

PURPOSE: We determined the prevalence of lower urinary tract symptoms in enuretic and nonenuretic children and adolescents in an urban community. MATERIAL AND METHODS: We performed a cross-sectional survey including 296 children and adolescents in a small urban community. Trained medical students visited all homes and interviewed the parents or guardians. There were no refusals to participate. Results were analyzed using chi-square and McNemar statistics. RESULTS: The enuresis rate was 10%, including 16.6% and 3.9% in children 5 to 10 years old and adolescents, respectively. The monosymptomatic enuresis rate was only 1.34%. Of those with vs without enuresis lower urinary tract symptoms were present in 86.7% vs 26.8% (p <0.001). In the nonenuretic group lower urinary tract symptoms were associated with nocturia (p = 0.008). The most common daytime urinary symptoms were urgency in 38.2% of cases, holding maneuvers in 30.4% and daytime incontinence in 27.5%. The prevalence rate decreased with age in the nonenuretic group (p = 0.013). CONCLUSIONS: The prevalence of lower urinary tract symptoms was high. Nonmonosymptomatic enuresis was common and monosymptomatic enuresis was rare in this population based survey. In nonenuretic cases daytime symptoms were associated with nocturia, suggesting decreased bladder capacity with a mature arousal reaction.

Detection and treatment of post kidney transplant hyperglycemia: a Spanish multicenter cross-sectional study.

INTRODUCTION: The prevalence of diabetes mellitus (DM) is greater among patients with solid organ transplants than in the general population, although the factors associated with posttransplant DM (PTDM) are unknown. OBJECTIVES: The objective of this study was to estimate the prevalence of and assess the risk factors for PTDM. PATIENTS AND METHODS: We included outpatients with functioning isolated solid organ allografts (kidney, liver, heart, and lung). We collected demographic and posttransplant clinical data that included DM diagnostic ADA criteria, DM treatment, DM family history, presence of hepatitis C virus (HCV), immunosuppression treatment, hypertension, and dyslipidemia. RESULTS: A total of 2178 patients included, 1410 kidney recipients, 489 liver transplants, 207 heart transplants, and 72 lung recipients. Seventeen and four-tenths percent of the patients who did not have DM prior to transplantation, developed PTDM (median time: 79 days). A greater prevalence was observed among patients with a family history, HCV, and tacrolimus treatment (with or without steroids P < .05). By logistic regression analyses, OR for these factors were 1.51, 1.65, and 1.38, respectively. Of those patients who did not suffer PTDM, 55.2% showed basal blood glucose values under 100 mg/dL; only 68% presented with a hemoglobin Alc under 6. CONCLUSIONS: The prevalence of PTDM among kidney recipients was higher than that in the general population. DM family history, HCV positive, and tacrolimus were risk factors associated with this entity.
