Patient Perspectives on Benign Prostatic Hyperplasia Surgery: A Focus on Sexual Health

BackgroundIn the last decade, many novel minimally invasive surgical techniques within benign prostatic hyperplasia (BPH) surgery were developed to reduce postoperative complications that often discourage patients from pursuing BPH surgery.AimTo assess perspective of future and past international BPH surgery patients regarding their postoperative complications, namely erectile and ejaculatory function.MethodsA survey was distributed randomly to 2 groups of BPH patients: one with 149 patients having undergone surgery in the last 2 years (group A), and the other cohort of 151 men seriously considering BPH surgery in the next year (group B). This survey consisted of 20 questions that assessed patients' motivating factors for undergoing elective BPH surgery and their perspectives regarding the potential postoperative complications attributed to BPH surgery.OutcomesThe perspective of future and past international BPH surgical patients towards the preservation of their erectile and ejaculatory functions was assessed with the help of a survey.ResultsResults indicated that in general BPH surgery patients considered the maintenance of erectile (95%, n = 284) and ejaculatory function (92%, n = 276) to be important preoperative considerations, regardless of their age. Patients aged 50–59 years were most concerned with the permanent impact on sexual function and patients aged >60 years were most concerned with urinary incontinence. In patients aged >70 years, 66% (n = 43) and 62% (n = 40) of the respondents indicated that maintaining erectile and ejaculatory function was important, respectively.Clinical ImplicationsPatient-centered care needs to be implemented in order to address the importance that past and future BPH surgery patients hold toward the maintenance of their postoperative sexual function.Strengths & LimitationsIn the group of patients having previously undergone BPH surgery, the possibility of recall bias should be taken into account when interpreting the study's findings. However, maintaining sexual function was also important for the group of patients seriously considering surgery in the next year suggesting that these considerations are not solely due to recall bias. Additionally, the results were limited by the small sample size of participants in groups A (n = 149) and B (n = 151).ConclusionIt was found that past and future BPH surgery patients attribute a significant importance toward the maintenance of their sexual function. Although novel approaches with better sexual outcomes such as Rezum and UroLift for prostates <80 mL, and Aquablation for any size prostate are available, more research is needed to investigate their long-term effects on sexual function before they can be recommended to patients.Bouhadana D, Nguyen D-D, Zorn KC, et al.

下颌角截骨面下部轮廓重塑的研究

目的:下颌角截骨是面型轮廓重塑中最常见的一种手术,为了提高手术的精确性,避免不必要的损伤,我们对各种下颌角截骨术操作技巧进行探讨.方法:术前进行面部测量、下颌骨曲面断层X线和头颅正侧位定位X线片投影测量,设计截骨线和去骨量,术式选择口内切口下颌角截骨术、口内切口下颌角外板矢状劈开截骨术、耳后切口下颌角截骨术、耳后和口内联合切口下颌角截骨术;结果:面下部过宽同时下颌角肥大者单纯下颌角截骨效果往往不会很理想,需要同时进行下颌角外侧骨板部分去除,减少面下部的宽度,206例术后两侧对称,效果良好;1例面瘫;2例下颌骨骨折,术中做内固定;3例下颌骨体部成角,3个月后第二手术将突出部分磨平.结论:术前测量设计下颌角截骨的术式和截骨线是十分必要的,根据下颌角肥大的不同类型选择相适应的截骨术式.     

Myocardial scintigraphy — 25 years after start

The development of myocardial scintigraphy (MS) reflects the clinical success of a representative procedure in nuclear medicine. Radiopharmaceuticals for visualizing vital and damaged myocardium and techniques (planar-qualitative, planar-quantitative, SPECT-qualitative — quantitative with comparative sensitivities) are briefly reviewed with the main focus on their clinical application in coronary (CHD) and noncoronary heart disease, where recent literature from the United States and Europe is considered. The limited value of MS for screening of CHD is outlined and its present and future role in detecting asymptomatic (silent) ischemia/infarction and asymptomatic patients at professional risk is stressed. The present state of MS in coronary heart disease is discussed for single and multivessel disease, previous infarction, and risk stratification (myocardial washout, pulmonary uptake, ischemic dilation, absent heart sign), reflecting the importance of the procedure in exercise-induced ischemia as well as in ischemia at rest for prognostication of the natural and therapeutic course, i.e., therapy control (angioplasty, bypass, lysis, cardiac drugs). More marginal but upcoming clinical indications are mentioned, such as progressive systemic sclerosis, cardiac transplantation, pediatric cardiology, and problems of nephrology/urology. The normal values and the impact of digital radiology and of contrast cardiography are touched upon. Preliminary cases with ¹¹¹In-antimyosin and ^99mTc-Isonitriles are presented including correlative results between global ejection fraction determination according to gated ^99mTc-isonitrile and conventional ^99mTc-erythrocyte ventriculogram (r=0,75; n=10).Dedicated to Prof. Heinz Hundeshagen on the occasion of his 60th birthday     

Sputum induction as a research tool for the study of human respiratory mucus

The study objectives were to compare in vitro transportability and physical properties of respiratory mucus, obtained invasively by direct collection (DC) right after endotracheal intubation and non-invasively by sputum induction with 3% hypertonic saline solution inhalation (SI) 24 h before the anesthesia. Twenty-two patients with no pulmonary disease scheduled for elective abdominal surgical procedures were studied. The parameters analyzed and the main results are as follows. (1) Transportability by cilia (MCT), SI was higher than DC (0.94+/-0.25 and 0.62+/-0.25; P<0.001). There was a significant correlation between the two methods and DC could be estimated by: DC=0.21+(0.44 SI) (r=0.44; P<0.001). (2) Transportability by cough (CC), SI was higher than DC (68.23+/-32.1 and 33.58+/-19.04 mm; P=0.002). (3) Contact angle (CA), SI was lower than DC (10+/-3 degrees and 22+/-14 degrees ; P=0.025). (4) Rheological properties (no significant difference obtained between SI and DC). These results indicated that SI changes mucus physical properties and transportability in non-expectorators.     

A case of dermatofibrosarcoma protuberans in the skin over the breast

Dermatofibrosarcoma protuberans (DFSP) is a slow-growing but locally aggressive, fibrous tumor that has a high rate of local recurrence after surgical resection. This tumor occurs most commonly in the trunk and proximal extremities. In this report we present a case of dermatofibrosarcoma protuberans in the skin over the breast which was re-excised after pathological diagnosis, considering cosmetic aspects. Only three other cases of dermatofibrosarcoma protuberans of the anterior chest wall have been encountered in our hospital, and all of these cases were male. The presence of this tumor in the skin over the breast appears to be rare in females. Careful complete resection is recommended for this type of tumor.
