Hormonal levels are the hallmark for the assessment of testicular function in XY DSD (Disorders of sex development). Traditionally, it has relied on testosterone level increment after hCG (human chorionic gonadotropin) stimulation testing. More recently role of Sertoli cell hormones is more emphasized.Objectives: Evaluating the role of serum anti-mullerian hormone and inhibin B on function of the pre-pubertal testis without the need for hCG stimulation test.Method: The study was conducted in the Endocrinology Clinic in Alexandria University Children's Hospital. All patients who present with XY DSD were tested for testosterone (T), dihydrotestosterone (DHT), Follicle stimulating hormone (FSH), luteinizing hormone (LH), anti-mullerian hormone (AMH), inhibin B. All cases had hCG stimulation test.Results: The hCG stimulation test was done for 32 cases. There was significant positive correlation between serum testosterone levels before and after hCG stimulation test (p <0.001). Similarly, significant correlation was identified between basal AMH and testosterone increment after hCG stimulation (p <0.001) and between basal levels of AMH and inhibin (MCp= 0.025).Conclusion: Single measurement of basal AMH and/or inhibin B can detect the presence and function of testes by a reliable non-invasive way. Basal AMH assessment is an important tool to distinguish between cryptorchidism and anorchia. hCG test is needed in the work-up of patients with inconclusive results.
The importance of the cool and modified atmosphere in cherry tomato fruit storing is its usage to increase the fruit longevity, quality appearance and prevention of spoilage diseases caused by Botrytis cinerea Pers.: Fr. and Alternaria alternata (Fr.) Keissi. Cherry tomatoes (Lycopersicon esculentum Mill. var. cerasiforme Dunal) was stored under cool condition and three modified atmosphere levels. Results clearly showed that modified atmosphere level (12% CO 2 + 6% O 2 ) under cooling storage (7ºC±1 + 90% RH±3), was significantly decreased incidence and severity percentage of cherry tomato spoilage more than the other two modified atmosphere levels. In parallel with this data our consequence proved that, these storage conditions preservation quality of cherry tomato parameters (firmness, TSS, vitamin C, lycopene and color) in pretty shape for consumer, marketing and exportation. Treated cherry tomatoes with calcium chloride and salicylic acid extending shelf life, improve fruit quality appearance and stability parameters of cherry tomato with less spoilage disease incidence under previously storage conditions.
Background Hemiscrotal agenesis (HSA) is an exceedingly rare congenital anomaly in scrotal development. It is characterized by unilateral absence of scrotal skin with intact midline raphe. In the English literature, only seven patients were diagnosed with HSA. Herein, we report a 14-month-old boy with HSA, unilateral cryptorchidism and a perineal skin tag. Additionally, the patient had a monodactylous limb, unilateral cerebellar hypoplasia, and a cardiac septal defect. Case presentation A 14-month-old boy presented with right HSA and ectopic scrotal skin in the right perineal region. Extra-genital examination showed right monodactylous lower limb, without dysmorphic facial features or any other skeletal anomalies. His karyotype was 46, XY, while his hormonal profile showed prepubertal LH and FSH. Skeletal survey showed right monodactylous lower limb (with only a big toe which had 2 phalanges) and normal spine alignment. A previous echocardiography was done and showed a small muscular ventricular septal defect (VSD) that closed on follow-up. Magnetic resonance imaging of the brain showed posterior fossa malformation. The patient had his right testis fixed in the right scrotum. The pathological examination of the perineal lesion showed fibro-epithelial polyp (skin tag), with no testicular tissue or atypia. Conclusion We believe that this is the first case to be reported with hemiscrotal agenesis and ipsilateral cryptorchidism, associated with a perineal skin tag, unilateral monodactylous lower limb on the same side, unilateral cerebellar hypoplasia, and VSD. Interestingly, further genetic analysis is required to reach a final diagnosis. However, regrettably, advanced molecular diagnostic studies for this patient is not available in our country.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
