Ultrasound Diagnosis and Active Ureteroscopy for Obstructive Ureteral Calculi During Pregnancy: Multicenter Experience.

To evaluate the safety and efficacy of ultrasound (US) and primary ureteroscopy (URS) in the management of symptomatic obstructive ureteric stones during pregnancy. A prospective multicenter study was performed between June 2013 and December 2019, including all consecutive pregnant patients admitted to three urology centers with intractable renal colic with obstructed ureter secondary to obstructive ureteral calculi. Color Doppler ultrasound was used to evaluate renal Resistive Index (RI) and ureter jet.

Drug-naïve Egyptian females with migraine are more prone to sexual dysfunction than those with tension-type headache: a cross-sectional comparative study.

Headache is one of the chronic disorders that can trigger sexual dysfunction due to complex mechanisms. This study recruited 120 consecutive patients from our outpatient clinics with migraine (n = 60), TTH (n = 60) as well as healthy age-matched controls (n = 60) for a total of 180 patients. All the participants were evaluated by the Arabic version of the female sexual function index (ArFSFI: 19 items), the abridged 5-item version of the international index of erectile function (IIEF-5), hospital anxiety and depression scale (HADS: 14 items), visual analog scale (VAS) score, and the headache impact test questionnaire (HIT-6TM: 6 items).

Evaluation of neoadjuvant gonadotropin administration with downregulation by testosterone prior to second time microsurgical testicular sperm extraction: A prospective case-control study.

Purpose: The aim of this prospective study was to determine whether there is a beneficial role of combining gonadotropin administration with testosterone downregulation in non-obstructive azoospermia patients prior to a second time microsurgical testicular sperm extraction after a negative one.

Methods: A total of 40 non-obstructive azoospermia men were recruited from a specialized IVF center from 2014 to 2016. Participants were divided equally into two groups: Group A was subjected to testosterone downregulation alone for 1 month and then combined with gonadotropin administration for 3 months prior to second time testicular sperm extraction; Group B (controls) underwent second time microsurgical testicular sperm extraction without prior hormonal therapy.

Factors determining the sperm retrieval rate in fresh versus salvage micro-TESE: a comparative cohort study.

Purpose: We studied prospectively the role of FSH, testis volume, age, duration of infertility, hormonal therapy, varicocelectomy and testicular histopathology in determining the sperm retrieval rate (SRR) in fresh versus salvage micro-TESE.

Methods: Our study analysed retrospectively the prospectively maintained database of 330 NOA patients who underwent micro-TESE either 1st or 2nd or 3rd timers from January 2017 to August 2018 from the Andrology Clinic of a specialized IVF centre. They were divided equally into 3 groups, group (1) were 1st timers, group (2) were 2nd timers and group (3) were 3rd timers, respectively.

Can spermatozoa be retrieved in non-obstructive azoospermic patients with high FSH level?: A retrospective cohort study.

We aimed in this retrospective study to evaluate non-surgical preoperative parameters and testicular histopathology in determining the sperm retrieval rate (SRR) in non-obstructive azoospermic (NOA) patients. We evaluated the data of 1,395 consecutive patients who underwent 1st time micro-dissection testicular sperm extraction (micro-TESE) that was done by fifteen different senior andrologists and a consequent undefined number of biologists assisting them in the operative rooms from January 2010 to May 2013 in a specialised IVF centre. Our study did not demonstrate any statistical significance between the mean age, the mean duration of infertility and finally, the mean of FSH levels of the patients with positive and negative micro-TESE outcomes (p-value 0.

Tribulus terrestris versus placebo in the treatment of erectile dysfunction and lower urinary tract symptoms in patients with late-onset hypogonadism: A placebo-controlled study.

Aging is associated with a series of morphological and functional modifications that leads to reduced physiological efficiency and atrophy of various organs and systems. Tribulus terrestris induces its effect in fertility and sexual functions through the steroidal saponins, particularly the dominant saponins protodioscin. We aimed in this study to evaluate the efficacy and safety profiles of Tribulus terrestris in aging males with partial androgen deficiency who suffered from erectile dysfunction and lower urinary tract symptoms.

Emetine Di-HCl Attenuates Type 1 Diabetes Mellitus in Mice.

Type 1 diabetes mellitus (T1D) is a chronic autoimmune disease characterized by beta cell destruction, insulin deficiency and hyperglycemia. Activated macrophages and autoimmune T cells play a crucial role in the pathogenesis of hyperglycemia in NOD murine diabetes models, but the molecular mechanisms of macrophage activation are unknown. We recently identified pigment epithelium-derived factor (PEDF) as an adipocyte-derived factor that activates macrophages and mediates insulin resistance.

MD-2 is required for disulfide HMGB1-dependent TLR4 signaling.

Innate immune receptors for pathogen- and damage-associated molecular patterns (PAMPs and DAMPs) orchestrate inflammatory responses to infection and injury. Secreted by activated immune cells or passively released by damaged cells, HMGB1 is subjected to redox modification that distinctly influences its extracellular functions. Previously, it was unknown how the TLR4 signalosome distinguished between HMGB1 isoforms.
