To determine the aspect of low lying pubic tubercle in development of inguinal hernia: A case control study

Introduction The incidence and risk factors for inguinal hernia (IH) is not a thoroughly evaluated issue of preterms. Prematurity is the single most important risk factor. There exists no study in our country which reported the incidence of IH in preterms. The purpose of this study is to investigate the incidence and time of diagnosis of IH in very low-birth-weight (VLBW) infants. Patients and Methods This retrospective case–control study was conducted in Etlik Zubeyde Hanim Women's Health Training and Research Hospital and included discharged VLBW infants with gestational age less than 32 weeks. Control group included gender, birth weight, and gestational age matched VLBW infants without IH. Results The incidence of IH was 10.1% in VLBW infants (70/693) and 16.1% in extremely low-birth-weight infants (19/174). Male/female ratio was found as 3.4:1. Most IH appeared as bilateral (40.0%). Time of diagnosis was 39 (37–42) weeks of postmenstrual age while 68.6% of infants were diagnosed after discharge. IH development increased by 2.3-folds by having respiratory distress syndrome and by 4.5 folds by achieving full enteral feeds on or after the 10th day. Conclusion Preterms with respiratory distress syndrome and those reach full enteral feeding on or after the 10th day should be monitored carefully for IH development. Bearing in mind that a significant amount of IH cases exhibit symptoms after discharge, neonatologists should inform the parents of premature infants of the issue and close attention should be paid in postdischarge follow-up examinations.

Congenital Abdominal Wall Defects

AbstractThe aim of this nationwide population-based case–control study was to assess the incidence of inguinal hernia (IH) among patients with congenital abdominal wall defects. All infants born with congenital abdominal wall defects between Jan 1, 1998, and Dec 31, 2014, were identified in the Finnish Register of Congenital Malformations. Six controls matched for gestational age, sex, and year of birth were selected for each case in the Medical Birth Register. The Finnish Hospital Discharge Register was searched for relevant diagnosis codes for IH, and hernia incidence was compared between cases and controls. We identified 178 infants with gastroschisis and 150 with omphalocele and selected randomly 1968 matched, healthy controls for comparison. Incidence of IH was significantly higher in gastroschisis girls than in matched controls, relative risk (RR) 7.20 (95% confidence interval [CI] 2.25–23.07). In boys with gastroschisis, no statistically significant difference was observed, RR 1.60 (95% CI 0.75–3.38). Omphalocele was associated with higher risk of IH compared to matched controls, RR 6.46 (95% CI 3.90–10.71), and the risk was equally elevated in male and female patients.Conclusion: Risk of IH is significantly higher among patients with congenital abdominal wall defects than in healthy controls supporting hypothesis that elevated intra-abdominal pressure could prevent natural closure of processus vaginalis. Parents should be informed of this elevated hernia risk to avoid delays in seeking care. We also recommend careful follow-up during the first months of life as most of these hernias are diagnosed early in life. What is Known:• Inguinal hernia is one of the most common disorders encountered by a pediatric surgeon.• Prematurity increases the risk of inguinal hernia. What is New:• Children with congenital abdominal wall defects have a significantly higher risk of inguinal hernia than general population.• Families should be informed of this elevated hernia risk to avoid delays in seeking care.

It has been suggested that hypogonadism increases the risk for inguinal hernia (IH). The aim of this study was to investigate any association between androgen deprivation therapy (ADT) for prostate cancer and increased risk for IH. The study population in this population-based nested case-control study was based on data from the Prostate Cancer Database Sweden. The cohort included all men with prostate cancer who had not received curative treatment. Men who had been diagnosed or had undergone IH repair ( n = 1,324) were cases and controls, where not diagnosed, nor operated on for IH, matched only on birth year ( n = 13,240). Conditional multivariate logistic regression models were used to assess any temporal association between ADT and IH, adjusting for marital status, education level, prostate cancer risk category, Charlson Comorbidity Index, ADT, time since prostate cancer diagnosis, and primary prostate cancer treatment. Odds ratio (OR) for diagnosis/repair of IH 0 to 1 year from start of ADT was 0.5 (95% confidence interval [CI] = [0.38, 0.68]); between 1 and 3 years after, the OR was 0.35 (95% CI = [0.26, 0.47]); between 3 and 5 years after, the OR was 0.39 (95% CI = [0.26, 0.56]); between 5 and 7 years after, the OR was 0.6 (95% CI = [0.41, 0.97]); and >9 years after, the OR was 3.68 (95% CI = [2.45, 5.53]). The marked increase in OR for IH after 9 years of ADT supports the hypothesis that low testosterone levels increase the risk for IH. The low risk for IH during the first 8 years on ADT is likely caused by selection of men with advanced cancer unlikely to be diagnosed or treated for IH.
