RESUMEN
Plastic reconstructions of oncological anorectal defects often prove to be very difficult and lead to prolonged hospitalisation due to severe bacterial contamination, neoadjuvant radiotherapy and chemotherapy and difficult anatomical conditions. There is no common standard for plastic reconstruction in such cases. We present a patient diagnosed with distal rectal cancer with infiltration of the anus and vagina, who underwent radical tumour resection of the rectum and anus as well as partial resection of the vagina. A severe necrotising infection occurred post-surgery, which resulted in an extensive defect of the pelvis and perineal region. This article provides a retrospective clinical evaluation and photographic documentation of the reconstruction of the vagina, pelvis and perineal region with a bilateral gracilis and gluteus muscle flap.

BACKGROUND: Cerebral palsy (CP) is the most common cause of childhood disability, typified by a static encephalopathy with peripheral musculoskeletal manifestations-most commonly related to spasticity-that are progressive with age. Hip displacement is one of the most common manifestations, observed to lead to painful degenerative arthritis over time. Despite the key role that spasticity-related adductor muscle contractures are thought to play in the development of hip displacement in CP, basic science research in this area to date has been limited. This study was initiated to correlate hip adductor muscle changes intrinsic to the sarcomere-specifically, titin isoforms and sarcomere length-to the severity of hip displacement in children with spastic cerebral palsy. METHODS: Single gracilis muscle biopsies were obtained from children with CP (Gross Motor Function Classification System (GMFCS) III-V; n = 10) who underwent adductor muscle release surgery for the treatment of hip displacement. Gel electrophoresis was used to estimate titin molecular weight. Sarcomere lengths were measured from muscle fascicles using laser diffraction. The severity of hip displacement was determined by measuring by Reimers migration percentage (MP) from anteroposterior pelvic x-rays. Correlation analyses between titin, sarcomere lengths, and MP were performed. RESULTS: The mean molecular weight of titin was 3588 kDa. The mean sarcomere length was 3.51 µm. Increased MP was found to be associated with heavier isoforms of titin (R2 = 0.65, p < 0.05) and with increased sarcomere lengths (R2 = 0.65, p < 0.05). Heavier isoforms of titin were also associated with increased sarcomere lengths (R2 = 0.80, p < 0.05). CONCLUSIONS: Our results suggest that both larger titin isoforms and sarcomere lengths are positively correlated with increased severity of hip displacement and may represent adaptations in response to concomitant increases in spasticity and muscle shortening. TRIAL REGISTRATION: As this study does not report the results of a health care intervention on human participants, it has not been registered.

INTRODUCTION: The nerve-to-masseter is one of the most frequently used neural sources in smile reanimation surgery. Very little information has been reported on patient experience with regard to reanimated smile usage and sequelae following transfer. The aim of this study was to quantify patient perception of nerve-to-masseter use in smile reanimation surgery. METHODS: An online questionnaire was developed based on the clinical expertise of our team, patient interviews, and existing questionnaires of facial palsy-related quality of life and temporomandibular joint dysfunction. All patients treated with nerve-to-masseter-driven smile reanimation surgery, both nerve transfers and muscle transplantations, between 2007 and 2016 with a valid email address were invited to participate. RESULTS: Of 171 operated patients, 122 with a valid email address were invited to participate. Seventy-one patients responded (63.4% female, mean age 51.1 years) after a median follow-up of 3.8 years. A voluntary smile while biting down at least "most of the time" was reported by 83.1% of patients; 46.5% reported ability to smile on the affected side without bite. A "normal" or "almost normal" spontaneous smile was reported in 23.9% of patients. A total of 18.3% of patients self-reported masseter muscle atrophy, and 1.4-14.1% reported temporomandibular joint dysfunction. Forty-one patients (57.7%) reported prandial movement of the face at least "most of the time," with 9 patients (12.7%) considering this bothersome. CONCLUSION: Patients report good voluntary smiling ability following nerve-to-masseter-driven smile reanimation surgery, with low rates of sequelae.

INTRODUCTION: Early ambulation is the principal objective in trans-femoral amputees. Postamputation modifications complicate the rehabilitation process due to a reduced control at the interface between stump and prosthesis. The aim of this study is to determine whether magnetic resonance imaging depicts the amount of fatty degeneration of the thigh muscles after trans-femoral amputation (TFA). METHODS: A total of 12 patients following a TFA on the basis of a bone neoplasm or metastasis with an evaluable postoperative MRI were identified. Using the Goutallier classification, the fatty degeneration of the thigh muscles was analyzed in the middle (M) and at the distal end (E) of the residual limb at T1 (10.6 months) and T2 (25.6 months). RESULTS: Analysis at two different levels showed different grades of fatty degeneration of thigh muscles after TFA at T1 and T2. Comparing fatty degeneration at both levels of the stump, the quadriceps femoris revealed a significant change (p = 0.01) at T1 and M. sartorius and adductor (p = 0.02) at T2. CONCLUSIONS: MRI is an excellent diagnostic tool to evaluate fatty degeneration after TFA. The highest amount of fatty degeneration of the quadriceps muscle was monitored within the first 10 months. Early physiotherapy is important to strengthen the remaining stump muscles during rehabilitation.
