Aim. To determine the impact of gene polymorphisms on detrusor contraction-relaxation harmony in children with lower urinary tract symptoms (LUTS). Materials and Methods. Toilet trained children older than 5 years of age with LUTS and normal neurological examination underwent videourodynamic study. The control group was composed of age matched children with no voiding complaints. The study group who filled out the voiding dysfunction symptom score before and after the treatment received standard oxybutynin treatment and was reevaluated 1 year after treatment. Genomic DNA was isolated from all patients and subjected to PCR for amplification. Genotyping of ARGHEF10, ROCK2, ADRB3, and CYP3A4 was carried out with Polymerase Chain Reaction- Restriction Fragment Length Polymorphism (PCR-RFLP) method. Results. 34 (45%) and 42 (55%) patients were enrolled in the study and control group, respectively. ARGEF10 GG, ADRB3 TC, and CYP3A4 AG genotype patients displayed insignificant difference between pre- and posttreatment voiding dysfunction symptom score and bladder volumes. Conclusions. The polymorphism of genes in the cholinergic pathway did not significantly differ clinical parameters. On the other hand, polymorphic patients in the adrenergic pathway seemed to suffer from clinical disappointment. For this reason, we think that the neglected adrenergic pathway could be a new therapeutic target for the treatment of anticholinergic resistant LUTS in children.
Sexual dysfunction is a common problem in chronic obstructive pulmonary disease (COPD). We aimed to assess the presence of erectile dysfunction (ED) in COPD patients. Ninety-three outpatients who had been diagnosed as COPD and followed in Bolvadin State Hospital, Afyon, Turkey, were included in the study. All patients underwent pulmonary function tests and arterial blood gas analysis. They completed International Physical Activity Questionnaire (IPAQ), Medical Research Council (MRC) Dyspnea Scale, Short Form 36-item Scale (SF-36), and International Index of Erectile Function (IIEF) Questionnaire. The mean age of 10 (10.8%) mild, 46 (49.5%) moderate, 28 (30.1%) severe, and 9 (9.7%) very severe COPD patients was 61.4 + 9.8 years. Varying degrees of ED were detected in 67.7% of COPD patients. All patients with hypoxemia had ED. IPAQ score and all SF-36 parameters were low in patients with ED, while MRC score was high. Forced expiratory volume in one second, forced vital capacity, partial pressure of oxygen in blood, oxygen (O 2 ) saturation, IPAQ score, and role-physical parameters were statistically low in ED patients (p ¼ 0.04, 0.02, <0.01, <0.01, 0.02, and 0.04, respectively); MRC score was statistically higher in patients with ED (p ¼ 0.02). Patients with moderate and severe ED had statistically lower score of mental health (p < 0.01 and p ¼ 0.02, respectively). There was a positive correlation between IIEF score and IPAQ scores (p < 0.01), MRC scores (p ¼ 0.01), general health (p < 0.01), role-physical (p < 0.01), role-emotional (p < 0.01), physical functioning (p < 0.01), and mental health (p < 0.01) parameters in SF-36. ED is frequently seen in COPD patients. Hypoxemia, smoking, and limitation of physical activity are thought to be associated with ED in COPD as mechanisms. Quality of life and the functional capacity are negatively affected with the presence of ED. It is important for a physician to question the sexual functions in patients with COPD. The presence of ED may be routinely considered in the daily practice of pulmonologists in COPD patients. Keywords COPD, sexual functions, erectile dysfunction IntroductıonSince chronic obstructive pulmonary disease (COPD) is a chronic disease of middle-aged or older people, comorbidities are frequently seen. With decreasing sexual interest, testosterone levels and sexual function by aging, and the presence of chronic illnesses, erectile dysfunction (ED) is one of these comorbid diseases.ED is a frequent type of sexual dysfunction among mature and aging men, which is characterized by the inability to have an erection during sexual activity. A broad-based public study (Massachusetts Male Aging Study) revealed an ED prevalence as high as 52% in males between the fourth and seventh decade of life.1 Dunn et al. demonstrated that 34% of males (mean age 50) within the general population complained about sexual problems and the most common complaint was ED.2 Both studies showed that ED prevalence increases with age.The mechanism of ED is not exactly clarified in...
Neurofibromatosis type 1 is an autosomal dominant transmitted disease with various clinical manifestations. The bladder is the most commonly affected organ in the genitourinary system. The malignant transformation of the disease is rare, and unlike malign tumors, the treatment option for benign disease is usually conservative. The size and localization of the mass determine the symptoms, most of which are usually not specific. In this paper, we aim to present a 15-year-old patient with neurofibromatosis type 1 with bladder involvement. The clinical presentation and treatment options of this disease are discussed in the light of the literature.
Objectives: Our aim was to review our pathological archive to find out the actual incidence of micropapillary pattern (MPP) in our urothelial carcinoma patient population and determine its correlation with clinical outcome. Patients and Methods: 14 out of 170 cases with complete clinical follow-up were clinicopathologically analyzed. The extent of MPP was determined as tumor percentage. Results: 12 further cases with MPP were defined in the review. The percentage of patients with positive MPP increased in parallel to the tumor stage. There was no considerable difference between MPP-positive and MPP-negative groups according to the progression rates in non-muscle-invasive and muscle-invasive groups. Progression-free survival was much shorter in MPP cases, but again without statistical significance. Also, there was no significant relation between percentage of MPP and progression-free survival. Conclusions: Awareness of pathologists about MPP and its highly possible relation with aggressive behavior must be raised, as it may be more common than reported. A multicentric review of a large number of cases with MPP is needed for a better definition of its biological behavior. Focal MPP cases may have a better prognosis but this needs to be confirmed.
Bladder augmentation is an important tool in the management of children requiring reconstructions for urinary incontinence or preserving of the upper urinary tract in congenital malformations. We reviewed the literature and evaluated the long-term results of enterocystoplasty in the pediatric age group and summarized techniques, experimental options and future perspectives for the treatment of these patients. For this purpose, a directed Medline literature review for the assessment of enterocystoplasty was performed. Information gained from these data was reviewed and new perspectives were summarized. The ideal gastrointestinal (GI) segment for enterocystoplasty remains controversial. The use of GI segments for enterocystoplasty is associated with different short and long-term complications. The results of different centers reported in the literature concerning urological complications after enterocystoplasty are difficult to compare because of the non-comparable aspects and different items included by different authors. On the other hand, there are more and more case reports about cancer arising from bowel segments used for bladder augmentation in recent publications.Although bladder reconstruction with GI segments can be associated with multiple complications, such as metabolic disorders, calculus formation, mucus production, enteric fistulas and potential for malignancy, enterocystoplasty is unfortunately still the gold standard. However, there is an urgent need for the development of alternative tissues for bladder augmentation.
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.
