Defibrotide for Sinusoidal Obstruction Syndrome/Veno-Occlusive Disease Prophylaxis in High-Risk Adult Patients: A Single-Center Experience Study

Sinusoidal obstruction syndrome (SOS), also known as hepatic veno-occlusive disease (VOD), is a serious complication after hematopoietic stem cell transplantation (HSCT). SOS/VOD usually occurs within 3 weeks of HSCT, but the 2016 European Society for Blood and Marrow Transplantation diagnosis criteria have been revised to include late forms. Prophylactic use of defibrotide is recommended in the pediatric setting, but its value remains uncertain in the adult population. We report here a single-center series of 63 adult patients considered at high risk for SOS/VOD who received defibrotide prophylaxis in combination with ursodeoxycholic acid between May 2012 and August 2016. The median duration of defibrotide therapy was 23 days. Bleeding occurred in 14 patients (21.5%). Defibrotide prophylaxis was discontinued in 7 patients (10.8%): 4 cases (6.3%) due to bleeding and 3 cases (4.6%) because of the need for antithrombotic therapy. Overall, SOS/VOD occurred in 4 cases (6.3%) within 21 days after HSCT (days 13 and 14) in 2 cases and late-onset SOS/VOD (days 57 and 58) in the other 2 cases. SOS/VOD was moderate in 1 case, very severe in 3 cases, with 2 deaths related to SOS/VOD. Cumulative incidence of grades II to IV acute graft-versus-host disease and transplant-associated thrombotic microangiopathy were 22.2% and 3.2%, respectively. With a median follow-up of 31 months (range, 10.7 to 60.3), the rates of 2-year overall survival, progression-free survival, incidence of relapse, and nonrelapse mortality were 56.5%, 49%, 28.7%, and 22.3%, respectively. In our experience defibrotide prophylaxis is associated with a low incidence of SOS/VOD after allogeneic HSCT in a high-risk adult population with an acceptable safety profile.     

Impact of Varicocelectomy on Gonadal and Erectile Functions in Men with Hypogonadism and Infertility

IntroductionPrevious reports linked varicocele in infertile males with Leydig cell dysfunction and hypogonadism.AimThe aim of this study was to determine the impact of varicocelectomy on serum total testosterone (TT) level and erectile function in men with infertility and clinical varicocele.MethodsThis study included 141 heterosexual infertile men diagnosed to have clinical varicocele. They were divided into two groups: group 1 (103 men), who had microsurgical varicocelectomy, and group 2 (38 patients), who decided to pursue assisted reproduction procedures. All participants completed the International Index of Erectile Function (IIEF)‐5 questionnaire and underwent semen analysis. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, and TT were measured both at recruitment time and 6 months later.Main Outcome MeasureChanges in serum TT and IIEF‐5 following varicocelectomy.ResultsIn group 1, the mean TT level increased significantly post‐varicocelectomy (379.1 ± 205.8 to 450.1 ± 170.2 ng/dL, P < 0.0001). No similar change was found in group 2. Out of the 49 patients in group 1 with hypogonadism at baseline assessment (TT < 300 ng/dL), 37 (75.5%) exhibited a postoperative normalization of TT. However, only 3/15 hypogonadal men (20%) in group 2 had normal testosterone levels at the second visit. IIEF‐5 scores improved significantly postoperatively in patients with hypogonadism (17.1 ± 2.6 to 19.7 ± 1.8, P < 0.001). Neither operating vein diameter 3.6 ± 0.57 mm nor testicular size 10.46 ± 3.3 mL correlated with the mean change in TT (71.1 ± 101.2 ng/dL) (r = 0.162, P = 0.183 and r = ?0.077, P = 0.536, respectively).ConclusionsVaricocele is associated with hypogonadism in some infertile patients. Varicocelectomy significantly improves serum testosterone in infertile men, especially those with hypogonadism. This improvement in TT level may be reflected in the IIEF score.

Bladder pain syndrome/interstitial cystitis: a reappraisal for the clinician

Bladder pain syndrome--formally known as interstitial cystitis--is a chronic bladder disorder characterized by pelvic pain and urinary irritability symptoms. The physiopathology is still unclear but is thought to involve bladder mucosal injury, inflammation and neurologic dysfunction. It is hard to diagnose this entity due to symptoms that are common to several other pathologies such as chronic pelvic pain, endometriosis, overactive bladder, urinary tract infection, and vulvodynia, and due to the lack of specific findings. A combination of history, physical examination, and diagnostic tools helps the establishment of the diagnosis by ruling out other similar pathologies. Treatment is multimodal and combines behavioral changes, drugs administered orally or intravesically and even surgery for refractory cases.     

Impact of pulmonary tuberculosis on menstrual pattern and fertility

Introduction and Study Objective: The association between pulmonary tuberculosis (TB) and female reproductive health problems is not well addressed. This study was done at Assiut University and Woman's Health University Hospitals to estimate the effect of pulmonary TB on menstrual patterns and fertility of women in childbearing age. Patients and Methods: This study composed of 429 women with pulmonary TB of childbearing age (study group) and 100 age‐matched healthy women (control group). A detailed medical history was obtained, and a clinical examination, routine investigations of pulmonary TB and transvaginal ultrasonography (TVS) were performed for all cases. Hysterosalpingography, combined laparoscopy and hysteroscopy were done for infertile women whenever indicated. Results: Menstrual abnormalities were reported in 66% of women in the study group. Secondary amenorrhea (112 cases, 26.5%, P < 0.001) and hypomenorrhea (86 cases, 20%, P < 0.001) were significantly higher in the study group than controls (2% and 3%, respectively). TVS diagnosed functional ovarian cysts in 85 patients in the study group (19.8%). After completing anti‐tuberculosis treatment, 76% of women with menstrual abnormalities (162/213) resumed normal menstrual cycles. Among the 68 cases who sought fertility within 1 year after completion of treatment, TB peritubal and fine intrauterine adhesions were confirmed by laparoscopy and hysteroscopy in two and one infertile woman, respectively (0.7% of study group). Conclusions: TB had marked reversible effect on the menstrual cycle but minimal association with genital TB and infertility. Pretreatment counseling of pulmonary TB women should include information on these reversible changes. Persistence of menstrual abnormalities or presence of infertility after completion of treatment should stimulate investigation for the possibility of genital tract involvement.

Numerical simulation of the PGNA signal from chlorine diffusion gradients in concrete

A nondestructive test method for detecting chlorides in concrete has been developed based on prompt gamma neutron activation (PGNA). Its performance has been modeled using a hybrid MCNP/optical ray tracing approach. Since the chlorides often come from de-icing salts applied to the concrete surface, the Cl concentration has a non-linear depth profile which is typically modeled by the erfc function. The signals from this distribution have been simulated for several significant Cl capture peaks to estimate the erfc function parameters.
