Simultaneous treatment of anterior vaginal wall prolapse and stress urinary incontinence by using transobturator four arms polypropylene mesh
Purpose: To evaluate the medium-term efficacy and safety of transobturator four-arm polypropylene mesh in the treatment of
high-stage anterior vaginal wall prolapse and concomitant stress urinary incontinence (SUI).
Materials and Methods: Between September 2010 and August 2013, a prospective single-center trial was performed to evaluate
women with stage≥3 anterior vaginal wall prolapse with or without SUI who presented to Labbafinejad Hospital, Teheran, Iran,
and underwent anterior vaginal wall repair with polypropylene mesh. Pre- and postoperative evaluation included history; physical
examination using the Pelvic Organ Prolapse Quantification system and cough stress test, both before and after reduction of prolapsed
structures; Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ); urinalysis and culture; and a
postvoid residual assessment. Complications were reported at a mean of 2 years of follow-up.
Results: A total of 71 patients underwent cystocele repair with the transobturator four-arm polypropylene mesh. Seven of the
patients were lost to follow-up. There were no perioperative complications. The anatomical success rate was 87.5%. The subjective
success rate was 92.1%. The PFDI and PFIQ were significantly improved after surgery (p<0.001). Among those with the simultaneous
complaint of SUI, 82% were cured without any additional procedure. Three patients (4.6%) experienced vaginal mesh extrusion.
Two patients (3.1%) reported worsening of dyspareunia after surgery.
Conclusions: The four arms polypropylene mesh is an effective device for simultaneous correction of anterior vaginal wall prolapse
and SUI with a low complication rate at a medium-term follow-up. The majority of the subgroup with concomitant SUI were
cured without a second simultaneous procedure
Lower Urinary Tract Symptoms in Patients with COVID-19: Results of a Cross-sectional Study
Objective: We aimed to investigate the effect of severe acute respiratory syndrome-coronavirus-2 infection on lower urinary tract function using validated questionnaires in patients with patients.
Materials and Methods: This descriptive cross-sectional study was conducted according to the inclusion and exclusion criteria on 709 patients with Coronavirus disease-2019 (COVID-19) on an outpatient basis from September 2020 to May 2021 in Kerman’s health centers. After signing the consent form and completing the demographic information, the International Consultation on Incontinence Questionnaire male Lower Urinary Tract Symptoms Modules and International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms questionnaires were completed. Finally, the data were analyzed using the SPSS version 26 software.
Results: Patients with COVID-19 (n=709) (365 questionnaires related to women and 344 questionnaires related to men) were examined on an outpatient basis. In general, 42.2% of women and 45.6% of men with COVID-19 had nocturia. The frequency of urination per day was higher than normal in 23% of women and 40.4% of men. In addition, 15% of women complained of a sense of urinary urgency while urinating, and 13.7% and 20% of men complained of straining and hesitancy in urinating, respectively. Similar to the males, the common symptoms in women were nocturia and increased daily frequency. In addition, with increasing age, lower urinary tract symptoms (LUTS) became common in COVID-19 patients.
Conclusion: The results of our investigation imply that people with COVID-19 may acquire or experience de novo LUTS, particularly storage symptoms. All symptoms were more in people over 50 years old than in those younger. COVID-19 infection should be investigated in any patient presenting with LUTS during the current pandemic. Further research is needed to clarify the exact pathophysiology of this correlation
An unusual cause of urinary incontinence: Urethral coitus in a case of Mayer-Rokitansky- Kuster-Hauser syndrome
Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rare anomaly in women and is characterized by congenital aplasia of the
uterus and vagina, with normal development of secondary sexual characteristics and a normal karyotype. We report a case of a
38-year-old women with MRKH syndrome that had experienced urethral sex for many years. She presented with urinary incontinence
and dyspareunia. The patient’s secondary sexual characteristics were normal, and examination revealed a widely open
incompetent megalourethra and an absent vagina. Laboratory studies confirmed a 46, XX karyotype. Imaging included ultrasonography
and magnetic resonance imaging, which indicated bilateral normal ovaries and a rudimental bicornuate uterus. After
confirming the diagnosis of MRKH, the patient underwent urethroplasty by urethral plication, antiincontinence surgery by autologous
fascial sling of the bladder neck, and the creation of a neo-vagina using a urethral flap. After 3 months, voiding cystourethrography
and uroflowmetry confirmed normal voiding. There were no postoperative symptoms of urinary incontinence, and the
patient was completely satisfied

MC1568 improves insulin secretion in islets from type 2 diabetes patients and rescues β-cell dysfunction caused by Hdac7 upregulation
Aims: It has in recent years been established that epigenetic changes contribute to β-cell dysfunction and type 2 diabetes (T2D). For example, we have showed that the expression of histone deacetylase 7 (HDAC7) is increased in pancreatic islets of individuals with T2D and that increased levels of Hdac7 in β-cells impairs insulin secretion. The HDAC inhibitor MC1568 rescued this secretory impairment, suggesting that inhibitors specific for HDAC7 may be useful clinically in the treatment of T2D. The aim of the current study was to further explore HDAC7 as a novel therapeutic target in T2D. Methods: Hdac7 was overexpressed in clonal β-cells followed by the analysis of insulin secretion, mitochondrial function, as well as cell number and apoptosis in the presence or absence of MC1568. Furthermore, the effect of MC1568 on insulin secretion in human pancreatic islets from non-diabetic donors and donors with T2D was also studied. Results: Overexpression of Hdac7 in clonal β-cells significantly reduced insulin secretion, mitochondrial respiration, and ATP content, while it increased apoptosis. These impairments were all rescued by treatment with MC1568. The inhibitor also increased glucose-stimulated insulin secretion in islets from donors with T2D, while having no effect on islets from non-diabetic donors. Conclusions: HDAC7 inhibition protects β-cells from mitochondrial dysfunction and apoptosis, and increases glucose-stimulated insulin secretion in islets from human T2D donors. Our study supports specific HDAC7 inhibitors as novel options in the treatment of T2D
HDAC7 is overexpressed in human diabetic islets and impairs insulin secretion in rat islets and clonal beta cells
Aims/hypothesis: Pancreatic beta cell dysfunction is a prerequisite for the development of type 2 diabetes. Histone deacetylases (HDACs) may affect pancreatic endocrine function and glucose homeostasis through alterations in gene regulation. Our aim was to investigate the role of HDAC7 in human and rat pancreatic islets and clonal INS-1 beta cells (INS-1 832/13). Methods: To explore the role of HDAC7 in pancreatic islets and clonal beta cells, we used RNA sequencing, mitochondrial functional analyses, microarray techniques, and HDAC inhibitors MC1568 and trichostatin A. Results: Using RNA sequencing, we found increased HDAC7 expression in human pancreatic islets from type 2 diabetic compared with non-diabetic donors. HDAC7 expression correlated negatively with insulin secretion in human islets. To mimic the situation in type 2 diabetic islets, we overexpressed Hdac7 in rat islets and clonal beta cells. In both, Hdac7 overexpression resulted in impaired glucose-stimulated insulin secretion. Furthermore, it reduced insulin content, mitochondrial respiration and cellular ATP levels in clonal beta cells. Overexpression of Hdac7 also led to changes in the genome-wide gene expression pattern, including increased expression of Tcf7l2 and decreased expression of gene sets regulating DNA replication and repair as well as nucleotide metabolism. In accordance, Hdac7 overexpression reduced the number of beta cells owing to enhanced apoptosis. Finally, we found that inhibiting HDAC7 activity with pharmacological inhibitors or small interfering RNA-mediated knockdown restored glucose-stimulated insulin secretion in beta cells that were overexpressing Hdac7. Conclusions/interpretation: Taken together, these results indicate that increased HDAC7 levels caused beta cell dysfunction and may thereby contribute to defects seen in type 2 diabetic islets. Our study supports HDAC7 inhibitors as a therapeutic option for the treatment of type 2 diabetes
Amplatz versus Balloon for Tract Dilation in Ultrasonographically Guided Percutaneous Nephrolithotomy: A Randomized Clinical Trial
Purpose. To compare balloon with Amplatz for tract dilation in totally ultrasonographically guided PCNL (UPCN). Methods. We randomized 66 patients candidate for sonographically guided PCNL in the flank position in two study groups. In the first group, we used single step Amplatz dilation (AG) technique in which the 28- or 30-French Amplatz dilator is used for tract dilation. In the other group, we dilated the tract using balloon dilator (BG). We compared procedure time, success rate of dilation, and postoperative clinical outcomes and cost between two groups. Results. The rate of short dilation was higher in the Amplatz group (57.6%) compared with Balloon group (36.4%) (P=0.08). When using Amplatz for lower pole access, short dilation occurred in 81% of cases compared with 44% in the BG (P=0.02). Overall operation was longer in the AG (80±21 versus 65±20 minutes P=0.02). Stone free rate was 87.9% in the AG compared with 72.7% in the BG (p=0.12). Mean cost of the surgery was 603±85 USD and 718±78 USD in the AG and BG, respectively (P=0.0001). Hemoglobin drop, transfusion rate, renal function alteration, duration of hospitalization, and complication rate based on Clavien classification were similar in both groups. Conclusions. AG showed a higher rate of short dilation compared with BG; consequently, overall operating time was significantly longer in the AG whereas BG was significantly more expensive than AG. Bleeding and other complications were similar in two groups. We observed an advantage for balloon dilation over Amplatz when approaching the lower pole calyxes
