The Duration of Intra-abdominal Hypertension and Increased Serum Lactate Level are Important Prognostic Markers in Critically Ill Surgical Patient's Outcome: A Prospective, Observational Study.

AIM: The present study analyzed the clinical significance of duration of intra-abdominal hypertension (IAH) associated with increased serum lactate in critically ill patients with severe sepsis. MATERIALS AND METHODS: Our study was an observational, prospective study carried out in the Surgical Intensive Care Unit (ICU) at J.L.N Medical College, Ajmer, Rajasthan, India. In our study, we included a total of 100 patients and intra-abdominal pressure (IAP) was measured through intravesical route at the time of admission and after 6, 12, 24, 48, and 72 h via a urinary catheter filled with 25 ml of saline. Duration of ICU and hospital stay, need for ventilator support, initiation of enteral feeding, serum lactate level at time of admission and after 48 h, and 30-day mortality were noted as outcomes. RESULTS: In our study, an overall incidence of IAH was 60%. Patients with cardiovascular surgery and renal and pulmonary dysfunction were 93.3%, 55%, and 60%, respectively, at the time of admission and 65%, 10%, and 10%, respectively, after 72 h of admission in the surgical ICU. Nonsurvivors had statistically significant higher IAP and serum lactate levels than survivors. Patients with longer duration of IAH had longer ICU and hospital stay, longer duration of vasopressors and ventilator support, and delayed enteral feeding. CONCLUSION: There is a strong relationship "risk accumulation" between duration of IAH associated with increased serum lactate and organ dysfunction. The duration of IAH was an independent predictor of 30-day mortality. Early recognition and prompt intervention for IAH and severe sepsis are essential to improve the patient outcomes.

Acute kidney injury in Pediatric Intensive Care Unit: Incidence, risk factors, and outcome.

OBJECTIVE: To determine incidence, risk factors, and outcome of acute kidney injury (AKI) in Pediatric Intensive Care Unit (PICU). MATERIALS AND METHODS: This is a prospective, observational study conducted in PICU of Department of Paediatrics, S.P. Medical College, Bikaner, from October 2013 to May 2014. In this study, 536 patients of aged 29 days to 16 years were screened for AKI according to the Pediatric Risk, Injury, Failure, Loss, End-stage Renal Disease (pRIFLE) criteria. Their clinical and biochemical data were recorded and followed up to their discharge/death. RESULTS: During the study period, 230 (42.9%) out of 536 patients developed AKI. Younger age (<5 years) and females (P ≤ 0.013) were more prone to develop AKI. Most common etiologies were septicemia, multiple organ dysfunction syndrome (MODS), gastroenteritis, and severe malaria (P ≤ 0.05). The maximal stage of AKI was stage "R" (49.1%), followed by "I" (29.5%) and "F" (21.3%). Major PICU-related risk factors were use of vasoactive drug (VD) and nephrotoxic drug (ND) and need of mechanical ventilation (MV) (P ≤ 0.05). Length of stay was significantly longer than non-AKI patients (P ≤ 0.05). Mortality in AKI (47.5%) was higher (P ≤ 0.05%) in comparison to non-AKI (25.56%). CONCLUSION: AKI is common in critically sick children, especially in younger age and in females with septicemia and MODS. Use of VD and ND and need of MV are common risk factors. AKI is associated with longer hospital stay and higher mortality. pRIFLE is better diagnostic criteria in early detection of AKI and reduction of their morbidity and mortality.

Bardet-Biedl syndrome a rare cause of cardiomyopathy.

Bardet Biedl syndrome (BBS) is a rare autosomal recessive condition characterized by retinitis pigmentosa, polydactyly, obesity, learning disabilities, hypogonadism and renal anomalies. Cardiomyopathy in association with BBS has previously being reported only twice in literature. We report a case of a patient presenting with features of cardiomyopathy, who was subsequently diagnosed to have BBS.

The Tei index and asymptomatic myocarditis in children with severe dengue.

This study aimed to assess myocardial involvement in infants and children with severe dengue (as per the new World Health Organization [WHO] classification 2009) using the Tei index. This prospective observational study was conducted in the Department of Pediatrics, PGIMER and the associated Dr. RML Hospital, New Delhi from August to December 2010. The study included 67 children (ages 3 months-14 years) who satisfied the WHO criteria for the diagnosis of probable dengue fever with warning signs or severe dengue and tested positive for dengue via immunoglobulin-M (IgM) capture enzyme-linked immunoassay (MAC-ELISA). The patients were subjected to a complete blood count, liver function tests, renal profile, electrocardiography, myocardial band enzymes of creatine phosphokinase (CPK-MB), chest x-ray, abdomen ultrasonography, and two-dimensional echocardiography with color-flow Doppler mapping. Ejection fraction and Tei index measurements were performed. Significantly fewer patients with severe dengue were found to have myocardial involvement at admission by ejection fraction (48 %) and E/E' (37 %), than by the Tei index (70 %). Of the 67 patients with severe dengue, one died, giving a case fatality rate of 1.5 %. At discharge, the Tei index persisted on the high side for patients with myocardial involvement, whereas the ejection fraction improved for the majority of them. Most of the patients with severe dengue had asymptomatic myocarditis, as evident by a deranged Tei index, which improved but did not normalize by the time of discharge, necessitating a longer follow-up period. For the majority of the patients, inotropic support was not required to maintain hemodynamic stability.

Ruptured sinus of Valsalva masquerading as rheumatic heart disease.

Ruptured sinus of Valsalva is a rare lesion in pediatric age group. We are reporting a twelve year old child with hyperdynamic circulation being diagnosed and treated as Rheumatic heart disease.
