Orchidopexy for undescended testis-rate and predictors of re-ascent.

PURPOSE: This study aimed to investigate the rate of re-ascent requiring re-operation after primary orchidopexy and to investigate eventual differences between the inguinal and scrotal approach as well as other potential predictors for re-ascent. METHODS: A retrospective cohort study of children treated for undescended testis (UDT) with orchidopexy between 2018 and 2022 was conducted. The primary outcome was re-ascent requiring re-operation, and the secondary outcome was atrophy rate. Independent variables were age, underlying conditions, side, surgical approach, operation time, bilaterality, congenital/ascended UDT, presence of scrotal hypoplasia, presence of a patent processus vaginalis, division of external oblique, and suture of the testis. Univariate and logistic regression were used to evaluate differences between groups and risk for re-ascent. RESULTS: A total of 662 testes in 554 patients were included. Re-operation occurred in 6% (7% with inguinal approach, 3% with scrotal approach, p = 0.04). Re-operation was associated with younger age, congenital UDT, and inguinal approach, but neither of these variables remained significant in multivariate analyses. Atrophy occurred in one testis. CONCLUSION: The rate of re-ascent was 6% and the atrophy rate was 0.15%. A larger study may find predictors for re-ascent but with very low absolute risk. The lower rate of re-ascent with the scrotal approach is probably due to selection bias.

Associations between Th1-related cytokines and complicated pediatric appendicitis.

The pathogenesis of appendicitis is not understood fully, and the diagnosis can be challenging. Previous research has suggested an association between a T helper (Th) 1-dependent immune response and complicated appendicitis. This prospective cohort study aimed to evaluate the association between serum concentrations of the Th1-associated cytokines interleukin (IL)-1α, IL-1ß, IL-2, IL-6, IL-10, IL-17A and tumor necrosis factor beta (TNF-ß) and the risk of complicated appendicitis in children. Appendicitis severity was determined through histopathological examination. A total of 137 children < 15 years with appendicitis were included with a median age of 10 years (IQR 8-12); 86 (63%) were boys, and 58 (42%) had complicated appendicitis. Children with complicated appendicitis had significantly higher concentrations of serum IL-6 and IL-10, and lower of TNF-ß. After adjustment for age, symptom duration, and presence of appendicolith in a multivariable logistic regression, a higher concentration of IL-6 remained associated with an increased risk of complicated appendicitis (aOR 1.001 [95% CI 1.000-1.002], p = 0.02). Serum concentrations of IL-1α, IL-1ß, IL-2, IL-10, IL-17A and TNF-ß were not significantly associated with the risk of complicated appendicitis. In conclusion, our results suggests that the systemic inflammatory response in complicated appendicitis is complex and not solely Th1-dependent.

National survey of physicians in Swedish child health centres finds insecurity and unawareness regarding management of undescended testicles.

AIM: To investigate underlying factors for previously reported shortcomings in child health centres' (CHC) referral process of boys with undescended testicles. METHODS: A total of 386 physicians working at Swedish CHCs were surveyed regarding their knowledge about undescended testicles and their clinical management. Multivariate regression analyses were performed to identify risk factors of non-adherence to guidelines and self-reported lack of clinical skills. RESULTS: The overall knowledge of the health benefits of undescended testicle surgery was high (89%), while two-thirds were unaware of surgery being recommended <1 year of age. One-fifth of respondents had never received guidance on examination techniques. Male gender (adjusted odds ratio [aOR] 0.51, 95% confidence interval [95% CI] 0.31-0.86), education in paediatrics (aOR 0.37, 95% CI 0.18-0.76) and more experience (aOR 0.02, 95% CI 0.01-0.09) significantly decreased the risk of unfamiliarity with examinations. More experience decreased the risk of stating the incorrect indications for undescended testicle surgery (aOR 0.17, 95% CI 0.03-0.95) and finding examinations difficult (aOR 0.22, 95% CI 0.07-0.72). Medical education outside Nordic countries was a risk factor for unawareness of guidelines (aOR 2.06, 95% CI 1.21-3.51). CONCLUSION: The knowledge and confidence level of the study population varied widely. The results indicate a need for further theoretical and practical education among Swedish CHC physicians.
