Acupuncture Reduces the Risk of Dysphagia in Stroke Patients: A Propensity Score-Matched Cohort Study.

Background: Post-stroke dysphagia (PSD) affects the quality of life in stroke patients, impairs their rehabilitation ability, and causes other complications following stroke. Currently, there is currently some understanding of PSD risk factors, but its protective factors remain largely unknown. Objective: To analyze the effects of acupuncture (AP) on dysphagia in stroke patients and explore its potential as a preventive therapy. Methods: Patients with a diagnosis of stroke from 2010 to 2019 were selected and followed until 2020, utilizing factors such as age, gender, stroke location, stroke type, and baseline comorbidity. To compare the incidence of dysphagia, equal numbers of stroke patients treated with and without AP (n = 1,809) were matched by 1:1 propensity scoring. The Cox proportional hazards model and Kaplan-Meier method were used to assess the risk of dysphagia as an outcome measure. Results: The stroke patients treated with AP had a lower risk of dysphagia after adjusting for age, gender, stroke location, stroke type, and baseline comorbidity [adjusted hazard ratio (AHR) = 0.43, 95% confidence interval = 0.37-0.49] compared with those in the non-AP cohort. AP also decreased the risk of PSD among different gender groups. The risk ratios were AHR = 0.45 and AHR = 0.33 for males and females, respectively. AP also reduced the risk for PSD among different age groups. The risk ratios were AHR = 0.20, AHR = 0.37, AHR = 0.41, and AHR = 0.45 for the 18-39, 40-59, 60-79, and >80 years-old groups. Regarding stroke types (ischemic, hemorrhagic, and mixed type), patients treated with AP had a lower risk (AHR = 0.47, 0.28 and 0.17, respectively). With respect to stroke location, the risk of PSD in AP-treated patients was decreased regardless of location: brain stem (AHR = 0.41), diencephalon (AHR = 0.13), or multiple lesions (AHR = 0.40), the risk of PSD in AP-treated patients was decreased. For all baseline comorbidities, AP attenuated the risk of dysphagia. The cumulative incidence of dysphagia was remarkably lower in the AP group than in the non-AP group (log-rank test, P = 0.000). Limitations: First, this was a single-center clinical retrospective study. Second, we did not classify the severity of stroke and dysphagia. Third, all data were extracted manually. Lastly, the sample size was relatively small. Thus, future studies with larger sample sizes are warranted to verify our findings. Conclusion: Acupuncture treatment attenuates the risk of dysphagia in stroke patients. Future research should increase the sample size and elaborate further on the details of the AP protocol.

[Restoration of partial penile defect by scrotal skin flap in combination with penile lengthening].

OBJECTIVE: To evaluate the feasibility and clinical efficacy of a scrotal skin flap in combination with penile lengthening for repairing penile defects. METHODS: From 1999 to 2008, 7 cases (19 to 42 years old) of penile defects were treated by scrotal skin flap in combination with penile lengthening. The average preoperative length of stubbed penis was 2.1 cm in flaccid (range: 1.0 to 3.0 cm) and 4.8 cm in erection (range: 3.0 to 5.5 cm). All cases were treated with penile elongation. And a bilateral scrotal skin flap supplied by anterior scrotal artery (n = 3) or whole anterior scrotum flap (n = 4) was used to cover the exposed penile shaft. The scrotal incision was sutured directly. RESULTS: There was no need for urethra reconstruction. It was simple to obtain the scrotal skin flap. And the operation might be quickly performed with a lesser hemorrhage as compared with penile reconstruction. The scrotal flaps survived without any necrosis and all wounds healed primarily with an excellent contour and erectile function. When followed up for 1 - 5 years, the average preoperative penile length was 6.4 cm in flaccid (range: 5.0 to 7.5 cm) and 9.5 cm in erection (range: 8.0 to 10.5 cm). All cases had normal functions of urination, erection and gonobolia. Five cases had satisfied sexual life and one experienced a sexual life. CONCLUSIONS: The method of restoring partial penile defect with scrotal skin flaps is both simple and efficacious. Reasonable appearance and penile length are restored in most cases with better sensory and erectile functions.

[Anatomic research and clinical application of modified penile elongation: a report of 205 cases].

OBJECTIVE: To investigate the application of penile cavernous bodies elongation combined with fat flap for the treatment of micro-penis. METHODS: Anatomic study was performed to study the thickness of penile suspension ligaments and the relationship between the penile erection stability and the mobilization of cavernous bodies crus. The suspension ligaments were divided and cavernous bodies crus were partially mobilized, so as to release part of the cavernous bodies from inferior ramus of pubis. Then the penis was elongated sufficiently. Local fat flap was transposed to fill the front space of pubis to make sure the effective elongation of penis. RESULTS: 205 cases of micro-penis were treated. The average length of the penis was 4.26 cm in the static state, 8.13 cm in erectile state before operation. After operation, it increased to 8.63 cm in the static state, 12.11 cm in erectile state. CONCLUSIONS: The cavernous bodies can be elongated 1-2 cm more with the modified method, while the stability of penile erection is not affected.
