Transient versus surgically managed small bowel intussusception in children: Role of ultrasound

Background:

To evaluate and compare the ultrasound (US) features of transient small bowel intussusception (SBI) with those which required surgical management.

Materials and Methods:

US features of 26 children with 32 intussusceptions from January 2014 to August 2014 were recorded and compared with follow-up imaging or surgical findings.

Results:

Transient SBI when compared to surgically managed intussusception has shorter length of intussusception (mean 2.25 cm, range 1.8-4.5 cm vs. mean 5.6 cm, range, 2.3-7.8 cm), smaller transverse diameter (mean, 1.2 cm, range 0.8-2.3 cm vs. mean, 3.3 cm, range 2.9-5.4 cm) and thin wall (mean, 3.3 mm, 2.3-4.9 mm vs. mean, 6.8 mm, range, 4.3-11.2 mm). Four out of five surgically managed intussusceptions were associated with the lead point while none of the transient SBI had any lead point. Peristalsis was absent in all surgically managed intussusceptions.

Conclusion:

Transient SBI is associated with a shorter length of intussusception, smaller transverse diameter, thin walls, absence of the lead point and visible peristalsis. All these findings may help in distinguishing it from those requiring surgical management.Key words: Children, surgically managed small bowel intussusception, transient small bowel intussusception, ultrasound     

Validation of digital ankle-brachial index as a screening tool in symptomatic patients with peripheral arterial disease

Introduction

There is scarcity of data validating portable digital ankle-brachial index (ABI) with contrast angiography in peripheral arterial disease (PAD). Our aim was to provide an objective analysis of the relationship between digital ABI (dABI) and peripheral angiographic data.

Inclusion body myositis in the rheumatology clinic

Inclusion body myositis is a rare sporadic inflammatory‐degenerative myopathy of the elderly. Despite being the commonest type of acquired myopathy after the age of 50, misdiagnosis is extremely common. The most frequent hurdle in identifying new cases is the wrong diagnosis of polymyositis or motor neuron disease. Novel insights into pathogenic mechanisms have heralded the quest for newer therapeutics as well as drug repurposing in this otherwise progressive disorder.     

Aluminum phosphide (celphos) poisoning in children: A 5-year experience in a tertiary care hospital from northern India

Background:

Aluminum phosphide (ALP) (celphos) is an agricultural pesticide commonly implicated in poisoning. Literature pertaining to the clinical manifestations and treatment outcome of its poisoning among children is limited.

Materials and Methods:

A retrospective chart review was conducted of the medical records of 30 children aged less than 14 years admitted to pediatric intensive care unit (PICU) of a tertiary care hospital in northern India. Demographic, clinical, and laboratory parameters were recorded. The outcome was categorized into “survivors” and “nonsurvivors.”

Results:

The Mean (SD) age of the enrolled children [19 males (63.3%)] was 8.55 (3.07) years. Among the 30 children, 14 (46.67%) were nonsurvivors and the rest 16 (53.33%) were survivors. Nonsurvivors had ingested significantly higher doses of ALP (P < 0.001), and showed higher time lag to PICU transfer (P 0.031), presence of abnormal radiological findings on chest skiagram (P = 0.007), and a higher Pediatric Risk of Mortality (PRISM) III score (P < 0.001) at admission. Use of magnesium sulfate was associated significantly with survival [odds ratio (OR) (95% CI): 0.11 (0.02-0.66); P 0.016].

Conclusion:

The present study highlights that survival among children with ALP poisoning is predicted by dose of ALP ingestion, time lag to medical attention, and higher PRISM score at admission. Use of magnesium sulfate could be associated with better survival among them.     

Gender and ethnic differences in red cell distribution width and its association with mortality among low risk healthy United state adults

Limited information is available about gender and ethnic differences in red cell distribution width (RCDW) with regard to its relation to mortality in a population free of cardiovascular (CV) disease and diabetes. To assess gender and ethnic differences in RCDW and their effect on the association between RCDW and mortality, the Third National Health and Nutritional Examination Survey (n = 15,460, 1988 to 1994) data were examined. Multivariate adjusted Cox proportional hazard analysis was performed to assess effect of gender and ethnicity on the association between RCDW and mortality (total, CV disease, and coronary heart disease [CHD]). RCDW (mean ± SE) was greater in black women (13.1 ± 0.03) and men (13.4 ± 0.02) compared to women of white (12.9 ± 0.02) and other (13.0 ± 0.07) ethnicities and men of white (13.3 ± 0.02) and other (13.3 ± 0.07) ethnicities, respectively (p <0.001). The interaction between RCDW and gender was statistically significant for all study outcomes (p <0.001) but nonsignificant for RCDW and ethnicity. After adjusting for key variables, RCDW in women was associated with adjusted hazard ratios of 1.22 (95% confidence interval [CI] 1.14 to 1.31) for all-cause mortality, 1.17 (95% CI 1.07 to 1.28) for CV deaths, and 1.18 (95% CI 1.03 to 1.35) for CHD deaths; in men, adjusted hazard ratios were 1.29 (95% CI 1.20 to 1.38) for all-cause mortality, 1.27 (95% CI 1.17 to 1.37) for CV deaths, and 1.25 (95% CI 1.13 to 1.39) for CHD deaths (p <0.05 for all). In conclusion, blacks and men have significantly greater RCDWs compared to whites and women. Greater RCDW is associated with a greater risk of mortality in men compared to women, whereas no effect modification is observed by ethnicity.
