To compare Gross & Ferguson and Mitchell-Banks repair techniques in children with congenital inguinal hernia.

Aims: To compare operating time, early complication(s) and outcome of Gross & Ferguson and Mitchell-Banks repair techniques in children with congenital inguinal hernia. Materials and Methods: A prospective randomized study including boys aged 1-12 years, was conducted over one year. The patients were allocated in two interventional groups based on the repair viz. Gross and Ferguson and Mitchell-Banks group. After hernia repair, the patients were followed up on the day of surgery and at one week for early complications. Results: Fifty patients were enrolled. Mean operating time in Mitchell-Banks technique was significantly more than Gross and Ferguson technique (p=0.00012). The incidence of fever in two groups was similar. Scrotal edema was statistically significant in MB group on both Post-Operative Day -1 and 7 (p=0.023 and p=0.034). No patient in either group had wound infection or scrotal hematoma on POD-1. One subject (2%) had scrotal hematoma in MB group on POD-7. A total of 12 subjects (24%) had Surgical Site Infection on POD-7. There was statistically higher incidence of SSI on Day-7 in GF group (32%) as compared to MB group (16%) (p=0.018). Conclusion: GF technique had lesser operating time, less incidence of scrotal edema and hematoma though higher rate of surgical site infections. In this respect, GF technique can be used as a simple and safe procedure.

A meta-analysis on the comparison between pediatric inguinal herniotomies performed with and without incising the external oblique aponeurosis in terms of recurrence and complications

RATIONALE@#There is a diversity of methods in performing pediatric inguinal herniotomy, but no consensus on which is the gold standard. The two most common are the Ferguson technique and the MitchellBanks technique. The objective of this meta-analysis was to compare the two techniques in terms of hernia recurrence and post-operative complications: namely hematoma, hydrocele, testicular ascent, and testicular atrophy.@*METHODS@#Three randomized controlled trials and one multi-center retrospective study were included in this meta-analysis. Using the Cochrane Collaboration tool and Newcastle-Ottawa quality assessment scale, all studies included were deemed to be of good quality and have low risk of bias. Revman 5.3 was used for all statistical analyses.@*RESULTS@#There was no significant difference in terms of hernia recurrence between the two techniques (OR = 0.85, 95% CI = 0.31- 2.36). For post-operative complications, hematoma (OR = 0.64, 95% CI = 0.37-1.13), testicular ascent (OR = 0.28, 95% CI = 0.05- 1.50), and testicular atrophy (OR = 2.02, 95% CI = 0.54-7.52) did not differ between the two techniques. Only the incidence of postoperative hydrocele significantly differed between the two techniques, being higher when the external oblique aponeurosis was opened (OR = 0.44, 95% CI = 0.27-0.70). @*CONCLUSION@# Performing pediatric inguinal herniotomy without opening the external oblique aponeurosis is a safe procedure and may be recommended as an optimal choice of method for uncomplicated cases.

Non-invasive ECG recording and QT interval correction assessment in anesthetized rats and mice / Eletrocardiograma não invasivo e avaliação da correção do intervalo QT em roedores anestesiados

Rats and mice are the most common species used in experimental cardiac electrophysiology studies. Electrocardiogram (ECG) recording shows paramount importance for monitoring arrhythmias and cardiac function in several disease models, including QT syndrome. However, the lack of standardized reference values and QT correction formula for different animal species and lineages represent a challenge for ECG interpretation. The aim of this study is to provide an improved method for ECG recording, establishing reference range values and determine the QT formulas with higher correlation to heart rate (HR). A total of 10 Wistar rats, 10 Swiss mice, 10 C57BL/6 mice and 10 FVB/NJ mice were used in the study. Animals were submitted to anesthesia with isoflurane and ECG recording was performed using a six-channel non-invasive electrocardiograph. QT was corrected using the following formulas: Bazzett, Fridericia, Mitchell, Hodges, Van der Water and Framingham. Normal range values for ECG parameters were established in all animals studied. Pearsons' correlation defined Hodges formula as the most suitable for QT correction. This study demonstrated an improved method of ECG recording with reference values for Swiss, FVB/NJ, C57BL/6 mice, and Wistar rats. Hodges' formula was the most effective formula for QT correction in rodents, whereas Bazett's and Friderica formulas were ineffective for such animals. The present work contributes to arrhythmias investigation in experimental cardiology and may reduce misinterpretations in rodents' ECG.(AU)

Ratos e camundongos são as espécies mais comumente utilizadas em estudos experimentais de eletrofisiologia cardíaca. O registro do eletrocardiograma (ECG) é de suma importância para o monitoramento de arritmias e função cardíaca em vários modelos de patologias. No entanto, a falta de valores de referência padronizados e a fórmula de correção do QT para diferentes espécies e linhagens animais representam um desafio para a interpretação do ECG. O objetivo deste estudo é fornecer um método melhorado para o registro de ECG, estabelecendo valores de referência e determinar as fórmulas QT com maior correlação com a freqüência cardíaca (FC). Um total de 10 ratos Wistar, 10 camundongos Swiss, 10 camundongos C57BL/6 e 10 camundongos FVB/NJ foram utilizados no estudo. Os animais foram submetidos à anestesia com isoflurano e o registro de ECG foi realizado com eletrocardiógrafo não invasivo de seis canais. O QT foi corrigido usando as seguintes fórmulas: Bazzett, Fridericia, Mitchell, Hodges, Van der Water e Framingham. Os valores da normalidade para os parâmetros do ECG foram estabelecidos em todos os animais estudados. A correlação de Pearson definiu a fórmula de Hodges como a mais adequada para a correção do QT. Este estudo demonstra um método melhorado de registro de ECG com valores de referência para camundongos Swiss, FVB/NJ, C57BL/6 e Wistar. A fórmula de Hodges foi a mais eficaz para correção de QT em roedores, enquanto as fórmulas de Bazett e Friderica apresentaram valores mais baixos de correlação. O presente trabalho contribui para a investigação de arritmias em cardiologia experimental e pode reduzir interpretações erradas no ECG de roedores.(AU)
