Proposal for changes in cystoscopic follow-up of patients with low-grade pTa bladder tumor

OBJECTIVES: The cystoscopic follow-up of superficial bladder cancer accounts for a considerable workload for urologists and is also an invasive procedure with high costs. There is a potential benefit both to the urologist and the patient if unnecessary cystoscopies can be avoided. METHODS: The recurrence and progression rates of 120 patients with pTa G1 or G2 and small (<4 cm) transitional cell carcinoma were evaluated retrospectively. RESULTS: The recurrence rate was 6.5% (8/120) at 3 months. The recurrence rates at 6 and 9 months were 6.7 (8/119) and 3.6% (4/112), respectively. However, when the third month (first check) was clear, the recurrence rates at 6- and 9-month cystoscopy were 4.3 (5/116) and 2.7% (3/111), respectively. The recurrence rate at 12 months was 8% (8/99). For G1 tumors, the recurrence rates at 3, 6, 9 and 12 months were 6 (5/84), 5 (5/83), 2.5 (2/80) and 7% (5/71), respectively. The same results for G2 tumors were 8 (3/36), 8 (3/36), 6 (2/32) and 10.5% (3/28), respectively. The progression rate for the first year was lower than 1%. The difference between G1 and G2 tumors according to recurrence rate within the first year was not statistically significant (p>0. 05). CONCLUSIONS: This study supports the proposal that for patients with small and welldifferentiated pTa tumors at diagnosis, if the first control cystoscopy is clear, it is appropriate to perform the second check cystoscopy 1 year from initial resection and subsequent controls yearly. One should note that the study group included the most suitable patients for cystoscopic follow-up according to size and multiplicity of the tumor. This change in policy is further supported by the fact that progression occured in less than 1% in this group of patients.     

Age-related changes in ovarian volume, antral follicle counts and basal follicle stimulating hormone levels: comparison between fertile and infertile women.

Our objective was to compare the relationship between age, basal follicle stimulating hormone (FSH) level and ultrasound-measured mean ovarian volume (MOV) and mean antral follicle counts (MFC) in a group of infertile and fertile women between the ages of 35 and 45 years. Menstrual cycle day 3 serum FSH, MOV and MFC were analyzed in 62 infertile and 53 fertile women. Basal FSH and MFC did not differ between infertile and fertile women, whereas MOV was significantly smaller in infertile women (p < 0.05). In the infertile group, there was a negative correlation between MOV and age (rho = -0.389, p < 0.05), between MOV and basal FSH (rho = 0.495, p < 0.01), and between MFC and age (rho = -0.553, p < 0.01). In the fertile group, there was a strong negative correlation between MOV and basal FSH (rho = -0.631, p < 0.01), and between MFC and basal FSH (rho = -0.710, p < 0.01). Mean basal FSH, MOV and MFC did not differ between subgroups of patients with different causes of infertility. In the infertile group, patients with small ovaries of volume less than 1.8 cm(3) (mean volume -1 SD) had higher mean basal FSH (p < 0.05) and lower MFC (p < 0.01) levels than patients with normal ovarian volume. In conclusion, transvaginal ultrasound (TVU) indices and indirect hormonal parameters of ovarian reserve were similar in infertile and fertile women aged between 35 and 45 years. It is suggested that, in infertile women above 35 years of age, TVU rather than hormonal parameters be preferred, based on our data showing a stronger association between age and TVU indices of ovarian reserve than between age and increase in basal FSH level. Thus, TVU assessment of ovarian volume and antral follicle counts is a practical and cost-effective, if not better, technique for ovarian reserve testing.     

Percutaneous nephrolithotomy in older children

PURPOSE: The aim of this study was to evaluate the safety and efficacy of percutaneous nephrolithotomy (PCNL) in pediatric patients, older than 8 years, without any technical and instrumental modifications. METHODS: The authors retrospectively evaluated the data of 16 percutaneously treated kidneys of 14 patients with a mean age of 11 years (range, 8 to 17). The mean stone burden was calculated as 301 mm2 (range, 120-750). Percutaneous accesses were done under fluoroscopic control, and 24F to 30F Amplatz dilators were used depending on patient size. Ultrasonic and laser lithotripsy were performed to fragment calculi. RESULTS: Mean operating time was 111 minutes (range, 60 to 210 min) and no intraoperative or postoperative major complication was observed. Mean hemoglobin drop after the procedure was 1.16 g/dL (range, 0.3 to 2.8). Blood transfusion was required in only 1 patient, and mean postoperative hospitalization was 4.6 days (range, 3 to 10). Stone-free rate was calculated as 69% (11 of 16), but with residual fragments smaller than 4 mm, the success rate becomes 100% at patient's discharge. CONCLUSIONS: PCNL is an effective and safe form of therapy in pediatric stone disease. Especially in older children the use of the same instruments and technique as in adults may achieve equal results without any increased risk of possible morbidity and need of blood transfusion.     

Effect of water extract of Turkish propolis on tuberculosis infection in guinea-pigs.

Mycobacterium tuberculosis (H(37)R(v))-infected guinea-pig model was used to investigate the effect of water extract of propolis (WEP). After subcutaneous inoculation of tubercle bacilli, each animal received oral WEP (n=9), isoniazid (n=5) or saline (n=6) as placebo and were sacrificed 30 days later. Formation of necrosis was less prominent in the group treated with WEP, but was not statistically significant (P>0.05). The granuloma formation in the same group was more prominent than the placebo and isoniazid groups; however, this finding failed to reach statistical significance by the Kruskal-Wallis test (P>0.05). These findings suggest that Turkish WEP may have a limited effect on the development of tuberculosis infection in this guinea-pig model.     

Editorial Commentary: Arthroscopic Fixation of Tibial Eminence Fractures—Which Technique Is the Best Has Not Been Defined Yet!

The tibial eminence fractures are most frequently observed in children and adolescents increasingly. Their classification and management are mainly made by the displacement of the fracture fragment. The surgical management has evolved from open to arthroscopic techniques. Various fixation techniques have been defined. Mainly, there are 2 types of fixation: screw and suture-based methods. Although recent studies have demonstrated the biomechanical advantages of newer suture-based fixation methods, the best method of fixation has not been defined, yet. Currently, nondisplaced and reducible fractures are managed nonoperatively, and displaced and irreducible fractures are managed operatively. Until the best surgical method is defined by higher level of evidence studies clinically, functionally, radiologically, and biomechanically, the type of fixation will be chosen by considering the experience of the surgeon, the clinical status of the patient, the availability of the implants, and the morphology of these fractures.     

Technological Advances in Penile Implant Surgery

BackgroundDuring the last century, surgical management of erectile dysfunction has evolved from an experimental concept to a core treatment modality with widespread use among the men's health community. Over time, innovations in materials, mechanical design elements, device coatings, and surgical technique have provided patients with low-risk, reliable, and reproducible erectile function with high satisfaction rates.AimTo provide a foundation for future innovation by improving understanding of historical penile prosthetics and the rationale behind incremental technological improvements for the contemporary Men's Health physician.MethodsLiterature review was conducted to generate a comprehensive review of historical technological innovations in penile implant surgery. Companies with FDA approved penile prosthetics in use in the United States were contacted for information regarding technological innovations in the past and future devices in development. A separate literature review was performed to identify any significant future device design elements being tested, even in the ex vivo setting, which may have future clinical applications.OutcomesTechnological innovations in penile implant surgery were described.ResultsCurrent options for the prosthetic surgeon include malleable penile prostheses (MPP), self-contained (2-piece) inflatable penile prostheses, and multicomponent (3-piece) inflatable penile prostheses. Current MPPs consist of a synthetic coated solid core which allow for manipulation of the penis for concealability while maintaining sufficient axial rigidity to achieve penetration when desired. Multi-component (3-Piece) IPPs currently include the Coloplast Titan and Boston Scientific/AMS 700 which consist of a fluid reservoir, intrascrotal pump, and intracavernosal cylinders. The devices have undergone numerous design updates to the cylinders, pump, reservoir, tubing, and external coatings to increase reliability and decrease short- and long-term complications.Clinical ImplicationsFuture innovations in penile prosthetic surgery seek to broaden the indications and applicability to the transgender community and improve both safety and functionality for patient and partner.Strengths & LimitationsThe review is limited primarily to penile prosthetics approved for current or historical clinical use in the United States and may not be representative of the global prosthetic environment. Additionally, the research and development of future innovations, particularly those provided by device manufacturers, is likely limited by non-disclosure to maintain a competitive advantage.ConclusionsPenile prosthetic surgery will undoubtedly remain integral to the treatment of erectile dysfunction, and education regarding the current state of technological innovation will empower the prosthetic surgeon and biomedical engineering community to improve contemporary patient care and drive the development of the next generation of implantable penile prosthetics.Barnard JT, Cakir OO, Ralph D, et al.

Comparison of patient satisfaction,quality of life,and bite force between elderly edentulous patients wearing mandibular two implant‐supported overdentures and conventional complete dentures after 4 years

This study compared two groups of patients who were elderly and edentulous, one group included subjects who had mandibular overdentures supported by two implants (Group I); the other groups wore conventional complete dentures (Group II). This retrospective study included 100 edentulous patients (50 from each group) with an average age of 67.86 years, who had been followed for 4 years. The groups were compared in terms of patient satisfaction, quality of life (QOL), and bite force. The bite force and patient satisfaction scores of Group I were found to be statistically significantly higher than Group II (p < .05). However, no statistically significant difference was found between the two groups’ QOL scores (p > .05) except on the physical pain subscale (p = .013). Based on these results, it can be concluded that after 4 years of function, subjects wearing mandibular overdentures supported by two implants had higher values for bite force and patient satisfaction scores, but similar QOL scores when compared to conventional complete denture‐wearers.
