Adult Female Patient with Untreated Truncus Arteriosus Type I and Torsion of Small Bowel Gastrointestinal Stromal Tumor: A Rare Case Report.

BACKGROUND Persistent truncus arteriosus is a rare congenital cyanotic heart defect characterized by a single ventricular outflow tract. Without surgical intervention, it has a poor prognosis in infancy. Here, we report an adult female patient with uncorrected truncus arteriosus type I, who presented with acute-onset abdominal pain due to torsion of a small bowel gastrointestinal stromal tumor (GIST). CASE REPORT A 41-year-old woman came to our Emergency Department with acute-onset lower abdominal pain for 2 days. Congenital heart disease, truncus arteriosus, had been diagnosed at birth, and there had been no surgical intervention. Abdominal computed tomography revealed a 10×9×12-cm mixed-density mass in the pelvic capacity. Transthoracic echocardiography revealed a 33-mm ventricular septal defect. The ascending aorta originated mainly from the right ventricle, and the pulmonary artery originated from the beginning of the aorta (type I truncus arteriosus, according to Collett and Edwards classification). After a quick and detailed preoperative workup, the patient underwent tumor resection by open surgery with general anesthesia. CONCLUSIONS This is the first case to report emergency surgery for a patient with uncorrected persistent truncus arteriosus due to torsion of a small bowel GIST. A multidisciplinary team with deep understanding of the disease entity was crucial. By considering the fixed hemodynamic and respiratory physiology, overtreatment and unrealistic goals were avoided. Eventually, the patient was discharged after being hospitalized for 2 weeks.

Testosterone undecanoate supplementation together with human chorionic gonadotropin does not impair spermatogenesis in males with isolated hypogonadotropic hypogonadism: a retrospective study.

Gonadotropin therapy is commonly used to induce virilization and spermatogenesis in male isolated hypogonadotropic hypogonadism (IHH) patients. In clinical practice, 5.6%-15.0% of male IHH patients show poor responses to gonadotropin treatment; therefore, testosterone (T) supplementation can serve as an alternative therapy to normalize serum T levels and promote virilization. However, treatment with exogenous T impairs spermatogenesis and suppresses intratesticular T levels. This retrospective study aimed to determine whether oral testosterone undecanoate (TU) supplementation together with human chorionic gonadotropin (hCG) would negatively affect spermatogenesis in IHH patients compared with hCG alone. One hundred and seven IHH patients were included in our study. Fifty-four patients received intramuscular hCG and oral TU, and 53 patients received intramuscular hCG alone. The median follow-up time was 29 (range: 12-72) months in both groups. Compared with the hCG group, the hCG/TU group required a shorter median time to normalize serum T levels (P < 0.001) and achieve Tanner stage (III and V) of pubic hair and genital development (P < 0.05). However, there were no significant differences in the rate of seminal spermatozoa appearance, sperm concentration, or median time to achieve different sperm concentration thresholds between the groups. In addition, there were no significant differences in side effects, such as acne and gynecomastia, observed in both groups. This study indicates that oral TU supplementation together with hCG does not impair spermatogenesis in treated IHH patients compared with hCG alone, and it shortens the time to normalize serum T levels and promote virilization.

Effect of adjuvant drug therapy after varicocelectomy on fertility outcome in males with varicocele-associated infertility: Systematic review and meta-analysis.

Varicocele is one of the common correctable causes of male infertility. Recent studies have demonstrated varicocelectomy in males with abnormal semen parameters was associated with better fertility outcome, but the effect of adjuvant drug therapy after varicocelectomy on fertility outcome in patients with varicocele-associated infertility remains undefined. Hence, the present meta-analysis was performed to assess the efficacy of adjuvant drug therapy after varicocelectomy. The protocol was registered with PROSPERO (No. CRD42018093749). Ten randomised controlled trails containing 533 patients with adjuvant drug therapy after varicocelectomy and 368 patients with no medical treatment after varicocelectomy were included. Our analysis revealed that the improvement in pregnancy rate after adjuvant drug therapy was insignificant. (OR = 1.70, 95%CI = 0.99-2.91), but resulted in significant improvements in sperm concentration (MD = 13.71, 95%CI = 5.80-21.63) and motility (MD = 4.77, 95%CI = 3.98-5.56) at 3 months, sperm DNA integrity (SMD = 3.13, 95%CI = 1.50-4.75) and serum FSH level (MD = -1.02, 95%CI = -1.79 to -0.24). Therefore, compared to no medical treatment, the adjuvant drug therapy, especially the use of antioxidants seems to be associated with better fertility outcome. However, more evidences with high-quality studies are necessary to conform its benefits.
