Does MRI help in the pre - operative evaluation of pelvic fracture urethral distraction defect? - a pilot study

ABSTRACT Objectives To study the usefulness of MRI in preoperative evaluation of PFUDD. Can MRI provide additional information on urethral distraction defect (UDD) and cause of erectile dysfunction (ED)? Materials and Methods In this prospective study, consecutive male patients presenting with PFUDD were included from Feb 2011 till Dec 2012. Those with traumatic spinal cord injury and pre-existing ED were excluded. Patients were assessed using IIEF questionnaire, retrograde urethrogram and micturating cystourethrogram (RGU+MCU) and MRI pelvis. Primary end point was erectile function and secondary end point was surgical outcome. Results Twenty patients were included in this study. Fourteen patients (70%) were ≤40years; fifteen patients (75%) had ED, seven patients (35%) had severe ED. MRI findings associated with ED were longer median UDD (23mm vs. 15mm, p=0.07), cavernosal injury (100%, p=0.53), rectal injury (100%, p=0.53), retropubic scarring (60%, p=0.62) and prostatic displacement (60%, p=0.99). Twelve patients (60%) had a good surgical outcome, five (25%) had an acceptable outcome, three (15%) had a poor outcome. Poor surgical outcome was associated with rectal injury (66.7%, p=0.08), cavernosal injury (25%, p=0.19), retropubic scarring (18.1%, p=0.99) and prostatic displacement (16.7%, p=0.99). Five patients with normal erections had good surgical outcome. Three patients with ED had poor outcome (20%, p=0.20). Conclusions MRI did not offer significant advantage over MCU in the subgroup of men with normal erections. Cavernosal injury noted on MRI strongly correlated with ED. Role of MRI may be limited to the subgroup with ED or an inconclusive MCU.

Comparative effectiveness of tepid sponging and antipyretic drug versus only antipyretic drug in the management of Fever among children: a randomized controlled trial.

OBJECTIVE: To compare the effectiveness of tepid sponging and antipyretic drug versus only antipyretic drug among febrile children. DESIGN: Randomized controlled trial. SETTING: Tertiary care hospital. PARTICIPANTS: 150 children 6 mo - 12 yr age with axillary temperature 101F. INTERVENTION: Tepid sponging and antipyretic drug (Paracetamol) (n=73) or only antipyretic drug (Paracetamol) (n=77). MAIN OUTCOME MEASURES: Reduction of body temperature and level of comfort. RESULTS: The reduction of body temperature in the tepid sponging and antipyretic drug group was significantly faster than only antipyretic group; however, by the end of 2 hours both groups had reached the same degree of temperature. The children in tepid sponging and antipyretic drug had significantly higher discomfort than only antipyretic group, but the discomfort was mostly mild. CONCLUSION: Apart from the initial rapid temperature reduction, addition of tepid sponging to antipyretic administration does not offer any advantage in ultimate reduction of temperature; moreover it may result in additional discomfort.

Trends in human birth weight across two successive generations.

OBJECTIVE: To determine the correlation between parental and offspring birthweight (BW) in India. METHODS: The study involved two birth cohorts of successive generations. The parental cohort comprised of 472 fathers and 422 mothers from an earlier study. Details of their anthropometry at birth and in adulthood were available. 1525 children born to them comprised the offspring cohort. BW was obtained from hospital records for the offspring cohort. Odds ratios and regression coefficients were calculated to estimate the risks of a low birth weight (LBW) parent producing a LBW baby and quantitate the effects after adjusting for confounders. RESULTS: A LBW mother had a 2.8 times risk (95%CI 1.2-6.4) of delivering a LBW baby (p=0.02) and a LBW father was twice as likely to produce a LBW baby (OR 2.2; 95%CI 1.0 - 4.8; p=0.05). Every 100g increase in maternal BW was associated with an increase in offspring BW of 14 g; the equivalent figure for paternal BW was 18.1g (p< 0.001 for both). Between the generations, the incidence of LBW decreased from 19.7% to 17.2% (p=0.1). Mean BW increased in males (2846 g vs 2861 g; p=0.59) but not in females (2790 g vs 2743 g; p=0.08). CONCLUSION: Both maternal and paternal BW are strong determinants of offspring BW. The effect of mothers' BW on offspring BW is weaker than that seen in developed nations. Stronger intrauterine constraint exhibited by Indian women secondary to a higher prevalence of growth restriction in utero may be responsible. Paternal effects may be governed by paternal genes inherited by the offspring.

Changing scenario of birthweight in south India.

Reducing incidence of low birthweight and increasing mean birthweights are now considered seriously in the national action plans. Comparison of birthweights obtained over two decades from the representative random segments of rural and urban areas of North Arcot Ambedkar district, Tamil Nadu, India, were studied. Although statistically significant (p < 0.001), the mean birthweight shows only a marginal increase of 70 g from 2774.5 g (+/- 500.2) in 1969-73 to 2845.4 g (+/- 451.0) in 1989-93. The mean birthweight stratified by area and gender also revealed similar increase. On the other hand, the proportion of low birthweight (< 2500 g) newborns reduced significantly from 27.2% to 15.9% in rural and 19.1% to 10.8% in urban area over the decades (p < 0.001). The increase in the mean birthweight and the decline in the percentage of low birthweight newborns over the years was greater in rural than the urban community, but the rural newborns continued to weigh lesser than their urban counterparts.

Factors associated with isolation of pathogenic bacteria from sputum of patients with acute bronchospasm.

Patients with obstructive airways disease (asthma and chronic obstructive airways disease) with an acute exacerbation of symptoms were studied. Those requiring hospitalization were chosen to study the pattern of respiratory pathogens isolated on a supervised sputum culture. Certain variables were studied in a case control design to determine an association with culture positivity.
