Título:Gluteal muscle damage leads to higher in vivo hip joint loads 3 months after total hip arthroplasty.

Resumen:BACKGROUND: Total hip arthroplasty (THA) is in most cases improving patients´ life quality immediately after surgery. However, a closer look at these patients, especially with modern gait analysis methods, reveals also negative consequences due to the surgical approach related injury to the pelvic muscles. We hypothesized that this damage will have a negative impact on hip joint contact forces during activities of daily living (ADL). METHODS: 10 patients undergoing THA received an instrumented hip joint implant enabling real time in vivo measurements of hip joint loads using a direct lateral approach. Pre- and 3 months postoperative computed tomography (CT) scans were used for evaluation of the periarticular muscle status, using muscle volume, fat ratio and lean muscle volume as parameters. An analysis of in vivo hip contact forces was made 3 months after THA during ADL (walking, stair climbing, chair rising and sitting) and correlated with the morphology of the periarticular muscles. RESULTS: We found a significant decrease of volume by 25% (-3 to -45, p = 0.005) and increase in fat ratio of the Gluteus Minimus (Gmin), resulting in a decrease in lean muscle volume of 28% (-48 to 0, p = 0.008). This was accompanied by an inverse development in the Tensor Fasciae Latae (TFL) resulting in a lean muscle volume increase of 34% (-2 to -102, p = 0.013). Changes in Gluteus Medius (Gmed) and Gluteus Maximus (Gmax) have not been observed in the short-term follow up. A decreased Gmin lean muscle volume was found to strongly correlate with high in vivo joint contact forces in all tested ADL. CONCLUSION: The decrease of Gmin volume can be seen as a direct effect of THA surgery, whereas the increase of TFL might compensate for loss of Gmin volume. Lean muscle volume and fat ratio were better predictors for joint contact forces than total muscle volume. These effects were most pronounced during sitting down and standing up due to the higher demand on the gluteal muscles during these activities.

Título:Application of gluteus maximus fasciocutaneous V-Y advancement flap combined with resection in sacrococcygeal pressure ulcers: A CONSORT-compliant article.

Resumen:BACKGROUND: Traditional gluteus maximus myocutaneous flaps have generally been used to fill tissue defects after resection of sacrococcygeal pressure ulcers. However, postoperative complications were gradually revealed as increasing operations were performed. This study aimed to introduce the innovative application of gluteus maximus fasciocutaneous V-Y advancement flaps for repairing tissue defects and to comparatively analyze the differences between the innovative and traditional flaps. METHODS: A total of 32 cases were included in this study. All the PU lesions were removed by resection. Sixteen cases used the gluteus maximus myocutaneous flaps, and the remaining 16 cases used gluteus maximus fasciocutaneous V-Y advancement flaps to fill the tissue defects after surgery. Comparative analysis between the gluteus maximus myocutaneous flaps and gluteus maximus fasciocutaneous V-Y advancement flaps was used to evaluate the 2 flaps based on the mean operating time, postoperative infection, paresthesia, appearance of flaps, and recurrence. RESULTS: The gluteus maximus fasciocutaneous V-Y advancement flaps required a reduced operating time and a more simple operation compared with the gluteus maximus myocutaneous flaps. Although the infectious risk of the gluteus maximus fasciocutaneous V-Y advancement flaps was reduced compared with the gluteus maximus myocutaneous flaps, the gluteus maximus myocutaneous flaps have a better appearance compared with the gluteus maximus fasciocutaneous V-Y advancement flaps. Most importantly, no flap necrosis was noted, and the recurrence rate during follow-up was reduced in cases using the gluteus maximus fasciocutaneous V-Y advancement flaps. CONCLUSION: The combined application of gluteus maximus fasciocutaneous V-Y advancement flaps with surgical resection can reduce the postoperative complications and aid in the treatment of sacrococcygeal pressure ulcers.

Resumen:Since its description in 1995, porokeratosis ptychotropica (PP) has remained a less-recognized variant of porokeratosis (PK). The term porokeratosis ptychotropica was coined in reference to its characteristic of affecting body folds. It mimics many other dermatological diseases and is therefore often misdiagnosed. We report a patient with multiple hyperkeratotic, warty lesions across the buttocks that mimicked cutaneous tuberculosis (CTB), but histological examination confirmed the correct diagnosis of PP.

Resumen:Gluteal augmentation with fat transplantation is increasing in demand but has been associated with a concerning number of fatality reports. Despite these reports, various surgeons have safely performed gluteal fat transplantation on a large number of patients with no reported mortality. The important aspects of safely performing gluteal fat transplantation are reviewed. Proper patient selection, favorable instrumentation, patient positioning, proper technique, and knowledge of anatomy are critical to improving the safety of this procedure. Adherence to these key principles should allow a reduction in mortality from this procedure, which would safely allow its continued offering in the setting of increasingly high demand.

Título:A cellular model for the investigation of depot specific human adipocyte biology.

Resumen:Upper-body adiposity is associated with increased metabolic disease risk, while lower-body adiposity is paradoxically protective. Efforts to understand the underlying mechanisms require appropriate and reproducible in vitro culture models. We have therefore generated immortalised ( ) human preadipocyte (PAD) cell lines derived from paired subcutaneous abdominal and gluteal adipose tissue. These cell lines, denoted APAD and GPAD display enhanced proliferation and robust adipogenic capacities. Differentiated APAD and GPAD adipocytes synthesize triglycerides de novo and respond lipolytically to catecholamine-stimulation. Importantly the cells retain their depot-of-origin 'memory' as reflected by inherent differences in fatty acid metabolism and expression of depot-specific developmental genes. These features make these cell lines an invaluable tool for the in vitro investigation of depot-specific human adipocyte biology.

Resumen:Liposarcomas correspond to the most common histological subtype of soft tissue sarcomas. They can be subdivided into: well differentiated or atypical lipoma, undifferentiated, myxoid, round, and pleomorphic cells. Atypical lipomas are the most prevalent and usually appear as asymptomatic softened tumors. They are locally aggressive but rarely lead to distant metastases. The diagnosis of this tumor is based on the imaging and histopathologic findings. Treatment consists of excision surgery with complete tumor removal. It has a good prognosis due to the low percentage of distant metastases. We report a rare case of giant atypical lipoma as well as the adopted therapy and evolution.

Título:Intramuscular hematoma with motor weakness after trigger point injection: A case report.

País de publicación:United States
Idioma:eng
Resumen:RATIONALE: Although trigger point injection is known as an easy and low-risk procedure, it is contraindicated to patients with hemorrhagic disorders or who regularly take anticoagulants/antiplatelets. However, taking clopidogrel is not a defined contraindication to this low-risk procedure. PATIENT CONCERNS: The chief complaint of a 76-year old woman regularly taking clopidogrel was low back and left buttock pain which prolonged for several years. DIAGNOSES: The patient was diagnosed with L4-5 and L5-S1 spinal stenosis at the orthopedics department and was referred for lumbar spinal epidural steroid injection. INTERVENTION: She was treated with trigger point injection. OUTCOMES: Three hours after the injection, she complained motor weakness and pain in the injection area. A hematoma on left gluteus medium muscle was detected with ultrasonography and ultrasound-guided needle aspiration was accomplished to relieve the symptom. LESSONS: Trigger point injection for patients taking clopidogrel should be done with a caution to prevent such complication.
