Fifty inguinal regions were dissected in anatomic human adult specimens, of which 26 were males and 24 females. The comparison of anatomic variations in both sexes showed that the distance between the public tubercle and the internal ring was larger, and the rectus muscle significantly wider in females. The diameter of the internal ring was larger in males, however, with significant variability. No differences were found regarding the presence or absence of the conjoint tendon. The anatomic variations may explain the sex differences in hernia formation. 相似文献

Patients with symptoms at the site of a previous inguinal hernia repair may constitute a diagnostic dilemma. The usefulness of herniography in the assessment of these patients was evaluated at 54 symptomatic sites in 46 subjects. Ten persistent or recurrent hernias were shown by herniography, only 2 of which were definitely detected on physical examination. The herniogram was normal at 44 sites, of which, on physical examination, 5 were equivocal and 1 was diagnosed as a definite hernia. On the unoperated-on or asymptomatic side, a total of 14 hernias were shown herniographically. Of these hernias, 8 were not detected on physical examination. Herniography was found to be more sensitive than physical examination in detecting hernias at the symptomatic, previously operated-on sites, as well as at the unoperated-on or asymptomatic sites. When a herniogram provides corroborative evidence that hernia has not recurred, the need for reexploration may be eliminated. 相似文献

Although the inguinal hernia is among the most commonly encountered and well-described health problems all over the world, the etiology is still controversial. The aim of this study was to compare the plasma and hernia sac tissue copper levels in direct and indirect inguinal hernia patients. Plasma and hernia sac tissue copper levels obtained from patients operated under spinal anesthesia with primary direct (group I, n = 55, 45 male, mean age = 45.68 yr) and indirect (group II, n = 55, 40 male, mean age = 38.57 yr) hernias were detected by atomic absorption spectrophotometer. Significantly lower plasma and hernia sac tissue copper levels were detected in group I in comparison to group II (p < 0.001). Both plasma and hernia sac tissue copper levels were significantly lower in males when we compare the patients according to their sex characteristics, including both direct and indirect hernia groups (p < 0.05 and p < 0.01, respectively). Age was not a significant factor. The plasma and hernia sac tissue copper levels were significantly lower in direct hernia patients in comparison to indirect hernia patients. Copper is a cofactor of lysyl oxidase, an important enzyme in collagen tissue metabolism, so there might be a defect in the collagen synthesis of direct hernia patients because of the decreased activity of the lysyl oxidase. Further investigations are necessary to clarify this concept. 相似文献

Inguinal hernia is a common disease, most cases of which are indirect inguinal hernia (IIH). Genetic factors play an important role for inguinal hernia. Increased incidences of inguinal hernia have been reported in patients with 22q11.2 microdeletion syndrome, which is mainly caused by TBX1 gene mutations. Thus, we hypothesized that altered TBX1 gene expression may contribute to IIH development. In this study, the human TBX1 gene promoter was genetically analyzed in children with IIH (n = 100) and ethnic-matched controls (n = 167). Functions of DNA sequence variants (DSVs) within the TBX1 gene promoter were examined in cultured human fibroblast cells. The results showed that two heterozygous DSVs were found, both of which were single nucleotide polymorphisms. One DSV, g.4248 C>T (rs41298629), was identified in a 2-year-old boy with right-sided IIH, but not in all controls, which significantly decreased TBX1 gene promoter activity. Another DSV, g.4199 C>T (rs41260844), was found in both IIH patients and controls with similar frequencies (P > 0.05), which did not affect TBX1 gene promoter activity. Collectively, our data suggested that the DSV within the TBX1 gene promoter may change TBX1 level, contributing to IIH development as a rare risk factor. Underlying molecular mechanisms need to be established. 相似文献

Calprotectin is one of the most abundant proteins of neutrophil granulocytes. It is released upon neutrophil activation and is considered a sensitive and clinically useful marker for neutrophil-mediated inflammation, including bacterial infections. However, early kinetics of calprotectin activation following inflammatory activation has hitherto been unknown. The aim of the present study was to determine the early phase of the kinetics of calprotectin, in comparison with the inflammatory markers CRP, IL-6, TNF-α, and procalcitonin, in plasma following a standardized temporary mild inflammatory response, using uncomplicated inguinal hernia surgery as a model. The study cohort consisted of 17 adult patients (15 male and 2 female) undergoing elective surgery for hernia. Values of calprotectin increased significantly at 2 h following surgery, and continued to increase to reach the highest level at 24–36 h after surgery, values still not exceeding upper normal reference level. This contrasts to IL-6 and CRP, for which an elevation was found first later, 4 h and 24–36 h post-surgery, respectively, for IL-6, and CRP. No significant increase was seen for TNF-α, or procalcitonin. The data demonstrate a very rapid and significant but modest increase in calprotectin following induction of mild inflammation, supporting that calprotectin can be useful for early detection of inflammatory response. 相似文献
