ABSTRACT
None: Diaphragm pacing (DP) by phrenic nerve stimulation is a modality of chronic ventilatory support in individuals with congenital central hypoventilation syndrome (CCHS). We report a 9-year-old girl with CCHS who uses DP without tracheostomy during sleep. Her parents report hypoxemia and hypercapnia related to positional changes of the body during sleep requiring frequent adjustment of pacer settings. Overnight polysomnography was performed to titrate DP settings that showed adequate gas exchange in the supine position, but intermittent hypoxemia and hypercapnia were noted in the left decubitus position without obstructive sleep apnea occurring. Subsequently, the DP amplitude settings were increased during polysomnography, thereby identifying and treating positional hypoxemia and hypercapnia in various body positions. Our case emphasizes the importance of polysomnography in children with CCHS using DP to monitor for sleep-disordered breathing and titration of DP settings to achieve optimal oxygenation and ventilation with different body positions during sleep.

None: Ventral thigh surface electromyography may be used to assess for periodic limb movements during sleep (PLMS) in a limb with an above-the-knee amputation. Presence of PLMS in the proximal portion of an amputated lower extremity supports theories of spinal and supraspinal mechanisms in PLMS generation, and demonstrates that intact distal motor efferent pathways and distal sensory afferent pathways are not absolutely necessary for the generation of periodic limb movements.

BACKGROUND: Clostridium difficile is the most common infectious cause of healthcare-associated diarrhea and is associated with worse outcomes and higher cost. Patients with septic shock (SS) are at increased risk of acquiring C. difficile infections (CDIs) during hospitalization, but little data are available on CDI complicating SS. OBJECTIVE: Prevalence of CDI in SS between 2007-2013 and impact of CDI on outcomes in SS. METHODS: Outcomes were prevalence of CDI in SS, effect on mortality, length of stay (LOS), and 30-day readmission. RESULTS: There were 2,031,739 hospitalizations with SS (2007-2013). CDI was present in 8.2% of SS. The in-hospital mortality of SS with and without CDI were comparable (37.1% vs 37.0%; ð = 0.48). Median LOS was longer for SS with CDI (13 days vs 9 days; ð < 0.001). LOS >75th percentile (>17 days) was 36.9% in SS with CDI vs 22.7% without CDI (ð < 0.001). Similarly, LOS > 90th percentile (> 29 days) was 17.5% vs 9.1%, ð < 0.001. Odds of LOS >75% and >90% in SS were greater with CDI (odds ratio [OR] 2.11; 95% confidence interval [CI], 2.06-2.15; ð < 0.001 and OR 2.25; 95% CI, 2.22-2.28; ð < 0.001, respectively). Hospital readmission of SS with CDI was increased, adjusted OR 1.26 (95% CI, 1.22-1.31; ð < 0.001). CONCLUSIONS: CDI complicating SS is common and is associated with increased hospital LOS and 30-day hospital readmission. This represents a population in which a focus on prevention and treatment may improve clinical outcomes.

Central venous line malposition is a well-known complication of line insertion. Rarely, it can be mal-positioned in an anomalous pulmonary vein. We present an unusual case of a 56-year-old woman that was found to have partial anomalous pulmonary venous return on central venous line insertion. In this report, we describe a systematic approach to diagnosis and management of this unusual situation.
ABSTRACT
We present a unique case of a patient with a tension pneumothorax that presented with electrocardiogram (ECG) characteristics typical for ST segment elevation myocardial infarction. The clinical diagnosis was clinched by focused physical examination. Treatment of the pneumothorax lead to resolution of the electrocardiographic abnormalities. Our experience from this unique case is useful for cardiologists and critical care physicians who encounter these patients routinely.

Type 2 diabetes mellitus (T2DM) is a global pandemic, as evident from the global cartographic picture of diabetes by the International Diabetes Federation (http://www.diabetesatlas.org/). Diabetes mellitus is a chronic, progressive, incompletely understood metabolic condition chiefly characterized by hyperglycemia. Impaired insulin secretion, resistance to tissue actions of insulin, or a combination of both are thought to be the commonest reasons contributing to the pathophysiology of T2DM, a spectrum of disease originally arising from tissue insulin resistance and gradually progressing to a state characterized by complete loss of secretory activity of the beta cells of the pancreas. T2DM is a major contributor to the very large rise in the rate of non-communicable diseases affecting developed as well as developing nations. In this mini review, we endeavor to outline the current management principles, including the spectrum of medications that are currently used for pharmacologic management, for lowering the elevated blood glucose in T2DM.
ABSTRACT
Background. Heart failure (HF) is one of the most common diagnoses associated with hospital readmission. We designed this prospective study to evaluate whether Kansas City Cardiomyopathy Questionnaire (KCCQ) score is associated with 30-day readmission in patients hospitalized with decompensated HF. Methods and Results. We enrolled 240 patients who met the study criteria. Forty-eight (20%) patients were readmitted for decompensated HF within thirty days of hospital discharge, and 192 (80%) patients were not readmitted. Compared to readmitted patients, nonreadmitted patients had a higher average KCCQ score (40.8 versus 32.6, P = 0.019) before discharge. Multivariate analyses showed that a high KCCQ score was associated with low HF readmission rate (adjusted OR = 0.566, P = 0.022). The c-statistic for the base model (age + gender) was 0.617. The combination of home medication and lab tests on the base model resulted in an integrated discrimination improvement (IDI) increase of 3.9%. On that basis, the KCQQ further increased IDI of 2.7%. Conclusions. The KCCQ score determined before hospital discharge was significantly associated with 30-day readmission rate in patients with HF, which may provide a clinically useful measure and could significantly improve readmission prediction reliability when combined with other clinical components.
