ABSTRACT Introduction To evaluate the safety and efficacy of a novel penile circumcision suturing devices PCSD and Shang ring (SR) for circumcision in an adult population. Materials and Methods A total of 124 outpatients were randomly assigned to receive PCSD (n=62) or SR (n=62). Patient characteristics, operative time, blood loss, return to normal activities time (RNAT), visual analogue scale (VAS), scar width, wound healing time, cosmetic result, and complications were recorded. Results There were no significant differences in blood loss, RNAT, or complications between the two groups. There were no significant differences in the VAS scores at the operation, at 6 or 24 hours after surgery (P>0.05). The wound scar width was wider in the SR group than in the PCSD group (P<0.01). Patients in the SR group had significantly longer wound healing time compared with those in the PCSD group (P<0.01). Patients who underwent PCSD were significantly more satisfied with the cosmetic results (P<0.01). Conclusions SR and PCSD are safe and effective minimally invasive techniques for adult male circumcision. Compared with SRs, PCSDs have the advantages of faster postoperative incision healing and a good effect on wound cosmetics.

Purpose: There is a paucity of data which reflected the relationship between morphology and incidence of shoulder disorders with respect to the ethnic Chinese population. We used anteroposterior radiographs to measure the Acromion Index (AI) and Acromioglenoid Angle (AA) of Chinese patients. The baseline was defined as the line that connected the superior and inferior osseous margins of the glenoid cavity. In order to calculate the AI, the distance from the baseline to the lateral margin of the acromion was measured and then divided by the distance from the baseline to the lateral aspect of the humeral head. The AA was defined as the angle formed by the intersecting line drawn tangent to the sclerotic line of the acromion undersurface and the baseline point. The AI and AA were determined in three groups: 165 patients (average age, 60.2 years) with chronic shoulder symptoms; in an age and gender-matched acute injury group of 61 patients (average age, 44.3 years); and in an age and gender-matched control group of 63 volunteers (average age, 37.3 years).The average AI and standard deviation was 0.72 ± 0.06 in shoulders with subacromial impingement syndrome, 0.59 ± 0.06 in those with acute injury, and 0.66 ± 0.06 in normal shoulders. The average AA and standard deviation was 76.8°±7.02 in shoulders with subacromial impingement syndrome, 84.2°±7.81 in those with acute injury, and 80.0°± 7.33 in normal shoulders. The AI and AA varied between patients with acute and chronic shoulder problems.

Hay escasez de datos que reflejen la relación entre la morfología y la incidencia de los trastornos de hombro con respecto a la población de origen chino. Se utilizó radiografías anteroposteriores para medir el índice acromial (IA) y ángulo acromioglenoido (AA) de los pacientes chinos. La línea de base se define como la que conecta los márgenes óseos superior e inferior de la cavidad glenoidea. Con el fin de calcular el IA, se midió la distancia desde la línea base hasta el margen lateral del acromion y luego se dividió por la distancia desde la línea base hasta la cara lateral de la cabeza humeral. El AA se define como el ángulo formado por la línea de intersección dibujada tangente a la línea esclerótica de la superficie inferior del acromion y el punto de línea base. El AI y AA se determinaron en tres grupos: 165 pacientes (edad media, 60,2 años) con síntomas crónicos en el hombro; en un grupo de 61 pacientes (edad media, 44,3 años) con herida aguda, y en un grupo control de 63 voluntarios (edad media, 37,3 años). La IA promedio fue de 0,72 ± 0,06 en los hombros con el síndrome de pinzamiento subacromial, 0,59 ± 0,06 en los pacientes con lesión aguda, y 0,66 ± 0,06 en los hombros normales. El AA promedio fue de 76,8 ° ± 7,02 en los hombros con el síndrome de pinzamiento subacromial, 84,2 ° ± 7,81 en los pacientes con lesión aguda, y 80,0 ° ± 7,33 en los hombros normales. La IA y AA variaron entre los pacientes con problemas en el hombro agudos y crónicos.
