Therapeutic effects of modified plantar skin grafting for the deep burn wounds of the back and butts / 中华创伤杂志

Objective:To compare the therapeutic effects of modified plantar skin grafting and thigh skin grafting on the deep burn wounds of the back and buttocks.Methods:A retrospective cohort study was conducted to analyze the clinical data of 30 patients with deep burn wounds on their back and buttocks who were admitted to the 910th Hospital of Joint Logistic Support Force of PLA from January 2021 to April 2023, including 26 males and 4 females, aged 21-72 years [(49.9±14.0)years]. The total burn size was 50%-97% of the total body surface area (TBSA), with the third-degree burn on the back and buttocks 6%-16% TBSA. The burn wounds on the back and buttocks were repaired using plantar skin grafts alone, thigh skin grafts alone or plantar skin grafts combined with the grafts from other body parts. The patients were grouped according to the skin graft donor sites and the times of harvesting skin grafts: there were 20 patients undergone plantar skin grafting including 10 patient with plantar skin graft harvested once (group of plantar skin graft harvested once) and 10 patients with plantar skin graft harvested twice or three times (group of plantar skin graft harvested more than once), and 10 patients undergone thigh skin grafting harvested once (group of thigh skin graft harvested once). The areas of plantar skin grafts harvested at the last time and the wound areas on the back and butts that could be repaired each time were calculated. After the last harvest, the thickness of the stratum corneum, 7-day survival rate of the skin grafts, proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month Vancouver Scar Scale (VSS) scores of the donor sites in the group of plantar skin graft harvested once were compared with those in the group of thigh skin graft harvested once and the group of plantar skin graft harvested more than once. The appearance and texture of the skin graft, patients′ walking patterns and complications were observed at 6 months after the last skin harvest.Results:All the patients were followed up for 6-18 months [(7.8±1.6)months]. In the 20 patients with plantar skin grafts harvested, the areas of skin grafts harvested at the last time were 2.5%-4.5% TBSA [(3.4±0.6)% TBSA] and the wound areas that could be repaired each time were 3%-8% TBSA [(5.5±1.5)% TBSA]. After the last harvest, the thickness of the stratum corneum in the group of plantar skin graft harvested once was (190.4±8.9)μm, which was significantly thicker than that in the group of thigh skin graft harvested once [(50.0±6.6)μm] and that in the group of plantar skin graft harvested more than once [(166.8±21.9)μm] ( P<0.01); the 7-day survival rate of the skin grafts, proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month VSS scores of the donor sites were (93.6±2.3)%, 2.0 (0.1, 3.5)%, (9.9±1.8)days and (1.7±0.7)points in the group of plantar skin graft harvested once, (78.0±6.6)%, 5.3 (4.0, 5.8)%, (14.0±1.4)days and (4.9±2.3)points in the group of thigh skin graft harvested once, and (93.4±2.6) %, 2.0 (0.1, 3.8)%, (10.0±1.2)days and (1.8±0.8)points in the group of plantar skin graft harvested more than once. The group of plantar skin graft harvested once showed a significant increase in the 7-day survival rate and a significant decrease in the proportion of 3-month residual wound area in the skin graft area, healing time of the donor sites, and 6-month VSS scores of the donor sites in comparison with the group of thigh skin graft harvested once ( P<0.05 or 0.01), while there were no significant differences in above mentioned indices between the group of plantar skin graft harvested once and the group of plantar skin graft harvested more than once ( P>0.05). At 6 months after the last skin harvest, the skin graft areas on the back and buttocks were flat, hard and firm and all the patients in the three groups could walk normally, with no complications such as severe itching, pain or folliculitis in the skin graft area. Conclusions:In the treatment of burn wounds on the back and buttocks, compared with thigh skin grafting, modified plantar skin grafting has advantages of thicker stratum corneum, better wear resistance and pressure resistance in the skin graft areas, a higher survival rate of skin grafts, rapid healing, mild scar, and undisturbed walking pattern after surgery and no common complications. Moreover, skin grafts can be harvested repeatedly from the donor sites, with no impact on the therapeutic effects.

Evaluation of the degree of aesthetic satisfaction after subcutaneous gluteal fat grafting / Avaliação do grau de satisfação estético após a lipoenxertia glútea subcutânea

Introduction: Body exposure, especially in the gluteal region, has increased the demand for gluteoplasty surgery. Autologous adipose tissue has been used to correct soft tissue defects since the beginning of the last century. Its smooth, natural texture, availability in sufficient quantities, and potentially permanent integration make adipose tissue the ideal physiological filler material. In this context, gluteal fat grafting, when compared with the use of gluteal implants, offers a faster recovery period and fewer complications in the medium and long term. Method: A prospective study was conducted using the gluteal evaluation questionnaire in patients who underwent subcutaneous gluteal fat grafting from August to December 2019. The collected data were submitted for statistical analysis by Student's t-test. Results: Forty patients (39 females and 1 male) who underwent subcutaneous gluteal fat grafting were selected. The average age presented in the study was 36.55 years. The mean body mass index was 27.38 kg/m2. The most frequent comorbidities were varicose veins, anemia, and hypertension. In most of the hypotheses evaluated, there was a significant improvement in the quality of life of the selected patients. Conclusions: Subcutaneous gluteal fat grafting improves patients' quality of life, which is demonstrated by the high level of satisfaction after performing this procedure.

Introdução: A exposição corporal, especialmente da região glútea, tem proporcionado atualmente um aumento da procura pela cirurgia de gluteoplastia. O tecido adiposo autólogo é usado para corrigir defeitos dos tecidos moles desde o início do século passado. Sua textura suave e natural, disponível em quantidades suficientes, e sua integração potencialmente permanente são características que fazem do tecido adiposo ser o material de preenchimento fisiológico ideal. Nesse contexto, a lipoenxertia glútea, quando comparada com o uso de implantes glúteos, oferece um período de recuperação mais rápido e menos complicações a médio e longo prazo. Método: Foi realizado um estudo prospectivo com a aplicação do questionário de avaliação dos glúteos nas pacientes submetidas a lipoenxertia glútea subcutânea no período de agosto a dezembro de 2019. Os dados coletados foram submetidos a análise estatística pelo teste t de Student. Resultados: Foram selecionados 40 pacientes (39 do sexo feminino e 1 do sexo masculino) que foram submetidos a lipoenxertia glútea subcutânea. A média da idade apresentada no estudo foi de 36,55 anos. A média do índice de massa corporal foi de 27,38 Kg/m2. As comorbidades mais frequentes foram varizes, anemia e hipertensão. Na maior parte das hipóteses avaliadas houve melhora significativa na qualidade de vida dos pacientes selecionados. Conclusões: A lipoenxertia glútea subcutânea melhora a qualidade de vida dos pacientes, o que é demonstrado pelo alto nível de satisfação após a realização desse procedimento.

Gluteoplastia com enxerto de gordura: experiência em 137 pacientes / Gluteoplasty with fat grafting: experience in 137 patients

Introdução: O conceito da estética feminina vem apresentando mudanças, com forte influência dos padrões culturais e regionais. Glúteos e mamas são as principais regiões enfatizadas, principalmente na América Latina. Diante disto, a lipoenxertia glútea adquire uma importância crescente. Neste trabalho, objetivamos estudar os resultados deste procedimento e suas complicações, sugerir uma classificação do formato dos glúteos e padronização de áreas a serem tratadas com a lipoenxertia. Métodos: Trata-se de um estudo prospectivo, realizado de janeiro de 2018 a fevereiro de 2020, com seguimento pós-operatório mínimo de 6 meses. Foi utilizada a técnica tumescente para obtenção da gordura, tratada por decantação, e injetada com seringa e cânula via sulco interglúteo e sulco subglúteo. Resultados: Dos 146 pacientes, nove foram excluídos, restando 137, sendo 132 mulheres e cinco homens. A idade média dos pacientes foi de 34,1 anos e o índice de massa corporal médio foi de 27,2Kg/m2. O formato de glúteo predominante foi o trapezoide (52,5%) e o volume médio de gordura injetado nos glúteos foi de 510,8ml no lado direito e 580,5ml no esquerdo, sendo as áreas central e lateral do glúteo as mais enxertadas. Quanto às complicações, a assimetria ocorreu em 3,65% dos pacientes, bolhas na pele em 2,9% e dor crônica em 2,2% deles. Conclusão: É um procedimento seguro com baixa incidência de complicações, quando é respeitada a restrição ao subcutâneo como plano de lipoenxertia, e de alta satisfação para os pacientes. A classificação e padronização sugeridas podem auxiliar a aprendizagem do procedimento.

Introduction: The concept of female aesthetics has been changing, strongly influenced by cultural and regional patterns. Buttocks and breasts are the main regions emphasized, especially in Latin America. Then, gluteal fat grafting becomes increasingly important. In this article, we aim to study the results of this procedure and its complications, suggest a classification of the shape of the buttocks and standardize areas to be treated with fat grafting. Methods: This is a prospective study realized from January 2018 to February 2020, and there was a follow-up of the patients for 6 months of postoperative. The surgical technique was tumescent to get fat, and decantation was the method to prepare the graft, which was injected through the intergluteal and subgluteal folds. Results: Of 146 patients, nine were excluded, remaining 137, of which 132 were women, and four were men. The mean age of patients was 34.1 years, and the mean body mass index was 27.2Kg/m2. The predominant gluteal shape was the trapezoid (52.5%), and the average volume of fat injected into the buttocks was 510.8ml on the right side and 580.5ml on the left, with the central and lateral gluteal areas being the most grafted. As for complications, asymmetry occurred in 3.65% of patients, skin blister in 2.9% and chronic pain in 2.2% of them. Conclusion: It is a safe procedure with a low incidence of complication when the fat grafting respects the subcutaneous plane, and this procedure has high patient satisfaction.

Choices for treatment of pressure sores in different parts of buttocks / 中华显微外科杂志

Objective:To explore the treatment of pressure sores in different parts of the buttocks.Methods:From May, 2005 to March, 2020, 170 (157 patients) pressure sores in different parts of buttocks were treated. Eighty-two pressure sores located at sacrococcyx, 52 at ischial tuberosity, 24 at greater trochanter (without hip joint exposure) and 12 at femoral greater trochanter with exposure of the hip joint. Flaps were used to repair the pressure sores. ①Seventy-one sacrococcygeal pressure sores were repaired by the gluteal epithelial neurovascular flap; ②10 (10 patients) sacrococcygeal and 42 (36 patients) sciatic tubercle pressure sores were repaired by the posterior femoral neurovascular flap; ③24(24 patients) femoral trochanter pressure sores and 1(1 patient) sacrococcygeal pressure sore were repaired by the tensor fascia lata myocutaneous flap; ④2 (2 patients) sciatic tubercle pressure sores were repaired by the gracilis myocutaneous flap; ⑤12 (10 patients) femoral trochanter pressure sores were with hip joint exposure treated with hip joint amputation; ⑥8 (8 patients) pressure sores at ischial tuberosity were treated with VSD. The pressure sores were measured at 5.0 cm×8.0 cm-15.0 cm×30.0 cm, and the flaps were sized 10.0 cm×12.0 cm-17.0 cm×32.0 cm. The follow-up was conducted in 2 methods: visit of outpatient clinic by patients and WeChat distanced interview by medical staff.Results:The gluteal epithelial neurovascular flaps, tensor fasciae lata flaps, gracilis myocutaneous flaps and posterior femoral neurovascular flaps all survived; 4 of 10 posterior femoral neurovascular flaps had partial necrosis and healed after dressing change. A total of 139 patients were treated by flap repair, of which 136 pressure sores healed, except 1 sacrococcygeal pressure sore and 1 femoral greater trochanter pressure sore did not heal because the patient was in old age, long-term hypoproteinaemia and anaemia, and 1 ischial tubercle pressure sore failed to heal due to osteomyelitis osteomyelitis. Ten pressure sores at femoral greater trochanter decubitus with hip joint exposure treated by hip joint amputation and 8 pressure sores at ischial tubercle decubitus treated by simple insertion of VSD were all healed. The follow-up period was 0.5-15.0 years, 7.5 years in average. The results of follow-up showed that pressure sores healed without recurrence in 154 patients, but failed to heal in 3 patients.Conclusion:The gluteal epithelial neurotrophic vascular flap has reliable blood supply and is simple to harvest, and it is a good flap to repair sacrococcygeal pressure sores. The tensor fascia lata myocutaneous flap has reliable blood supply and is simple to harvest, hence it is a good flap to repair greater trochanteric pressure sores. Transposition of the posterior femoral cutaneous nerve nutrient vessel flap or the V-Y advancement flap is simple and effective in repair of the sciatic tuberosity pressure sores. However, it is not recommended to apply the transposition of posterior femoral cutaneous nerve nutrient vessel flap in repair of the sacrococcygobtaineal pressure sore, because it would cause a necrosis at the distal part of the flap. When a greater trochanteric pressure sore coexists with an expose of hip joint, the hip joint can be dissected. For the pressure sore at ischial tuberosity, and if there is a small wound with a large internal cavity, it can be treated with simple insertion of VSD.

The absence of piriformis muscle, combined muscular fusion, and neurovascular variation in the gluteal region

The gluteal region contains important neurovascular and muscular structures with diverse clinical and surgical implications. This paper aims to describe and discuss the clinical importance of a unique variation involving not only the piriformis, gluteus medius, gluteus minimus, obturator internus, and superior gemellus muscles, but also the superior gluteal neurovascular bundle, and sciatic nerve. A routine dissection of a right hemipelvis and its gluteal region of a male cadaver fixed in 10% formalin was performed. During dissection, it was observed a rare presentation of the absence of the piriformis muscle, associated with a tendon fusion between gluteus and obturator internus, and a fusion between gluteus minimus and superior gemellus muscles, along with an unusual topography with the sciatic nerve, which passed through these group of fused muscles. This rare variation stands out with clinical manifestations that are not fully established. Knowing this anatomy is essential to avoid surgical iatrogeny.

Effects of free perforator propeller flap from buttock in repairing deep wound of buttock / 中华烧伤杂志

Objective@#To explore the effects of free perforator propeller flap from buttock in repairing deep wound of buttock.@*Methods@#From February 2016 to May 2018, 27 patients with buttock skin and soft tissue defects caused by various reasons were admitted to the Burn and Plastic Surgery Center of the 940th Hospital of the Joint Logistic Support Force of People′s Liberation Army, including 19 males and 8 females, aged from 28 to 70 years. Among the protopathy, there were 14 cases of pressure sores, 7 cases of scar carcinoma, 2 cases of low-temperature scald, 2 cases of abscess, and 2 cases of pilonidal sinus. The wounds were located in the sacrococcygeal region in 15 cases, the ischial tuberosity in 8 cases, and the rest area of buttock in 4 cases after injury or lesion resection. The size of wounds ranged from 4.0 cm×4.0 cm to 12.0 cm×6.0 cm after debridement or extended resection. The free perforator propeller flaps from buttock with areas of 8.0 cm×4.0 cm-16.0 cm×6.0 cm were used to repair the wounds, and the donor sites were selected adjacent to the wounds where the skins were relatively loose. All flaps took buttock free perforator vessels as the axis and were transferred in propeller-type to repair the wounds. The donor sites were directly closed and sutured. The survival, complications, and follow-up of flaps were recorded.@*Results@#All the flaps survived 100% in 27 patients. Congestion formed under flaps 2-6 days post operation in 2 patients due to inadequate drainage, which were healed after dressing change and drainage for 14-18 days. The sutures of flaps in the other cases were removed in 10-14 days post operation, and the wounds were healed. Follow-up for 2-12 months showed that the shapes of flaps and the donor sites were plump, which were not much different from the healthy sides, and the flaps could bear weight.@*Conclusions@#Repairing buttock deep wound with buttock free perforator propeller flap has good effects. The donor site can be designed in the area adjacent to the wound where the skin is relatively loose and can be directly closed and sutured while repairing the wound, which can ensure plump buttock appearance.

Carcinoma de células de Merkel de región glútea. Reporte de un caso / Merkel cell carcinoma of the gluteal region. Report of a case / Carcinoma de células de Merkel de região glútea. Relato de caso

Resumen: Introducción: el carcinoma de células de Merkel es un tumor primario maligno de piel que afecta fundamentalmente regiones expuestas a las radiaciones solares. Pocos casos han sido comunicados en una región no expuesta al factor de riesgo mencionado, como es la glútea. El objetivo de este trabajo es comunicar un caso clínico de carcinoma de células de Merkel de región glútea. Caso clínico: paciente de 63 años, sexo masculino, que consultó por tumoración de 2 cm de diámetro en región glútea derecha, de rápido crecimiento, que se operó de coordinación con anestesia, realizándose su resección completa. El resultado del estudio anatomopatológico informó carcinoma de células de Merkel. No se evidenció diseminación a distancia, por lo que de acuerdo con la clasificación TNM se determinó como estadio I. Se completó el tratamiento con radioterapia local. Actualmente el paciente sigue en seguimiento y asintomático. Discusión: los carcinomas de células de Merkel son tumores altamente agresivos. Además de la radiación solar como factor de riesgo, se mencionan la inmunodeficiencia y un nuevo poliomavirus, el poliomavirus de células de Merkel. Se presentan como tumoraciones de color violáceo y rápido crecimiento, y es frecuente el compromiso ganglionar sincrónico o metacrónico. La resección quirúrgica con márgenes suficientes y vaciamiento ganglionar, en caso de haber compromiso o estudio de ganglio centinela en caso de no haberlo, es lo indicado. El pronóstico depende del estadio y se ha reportado hasta 30% de recidiva a dos años.

Summary: Introduction: Merkel cell carcinoma is a malign primary tumour that mainly affects regions that are exposed to solar radiation. Few cases have been reported in a region that is not exposed to the above mentioned risk factor, as the gluteal regions. The study aims to communicate the clinical case of a Merkel cell carcinoma of the gluteal region. Clinical case: 63-year-old male patient who consulted for a tumour with a 2cm diameter in the right gluteal region, rapidly growing, being completely resected in a cordinaterd surgery under anesthesia. Pathology study revealed that it was Merkel cell carcinoma. No distance dissemination was seen, and thus as per the TNM staging system it was classified as stage I. Therapy was completed with local radiotherapy, It is currently under follow up and asymptomatic. Discussion: Merkel cell carcinoma are highly aggressive tumours. Apart from solar radiation as a risk factor, it is worth mentioning immunodeficiency and a new polyomavirus, the Merkel cell polyomavirus. This condition can be seen as purple, rapidly growing tumours and they frequently involve synchronic or metachronic lymph node compromise. Surgical resection with sufficient margins and lymph node emptying, in the event of lymph node compromise or sentinel node biopsy is recommended. Prognosis depends on the stage and a 30% relapse has been reported after 2 years.

Repair of skin and soft tissue defects of vulva, vagina, and buttock with internal pudendal artery perforator " angel wing" island flaps in six cases / 中华烧伤杂志

From November 2015 to July 2017, six patients with skin and soft tissue defects of vulva, vagina, and buttock after resection of vulvar tumors were hospitalized in our unit. All patients were female, aged 45-70 years. Among them, four patients had bilateral defects, and two patients had unilateral defect. The defect area on each side ranged from 6 cm×4 cm to 12 cm×6 cm. Internal pudendal artery perforator " angel wing" island flaps were used to repair and reconstruct the defects. The area of flaps ranged from 7 cm×5 cm to 14 cm×7 cm. The donor sites were sutured directly. All 10 flaps of 6 patients survived. Two patients had local incision infection 3 days after operation. One of the two patients was healed 2 weeks after dressing change, and the other one underwent debridement and suture 1 week after dressing change and was healed 1 week after surgery. Follow-up for 6-12 months after surgery showed no recurrence of tumors, no eversion of vagina, better shape of vulva in bilateral reconstruction cases, and slightly worse symmetry in unilateral reconstruction cases. The skin of the reconstructed area was soft, with sensations of pain, temperature, and touch recovered in varying degrees. The distance of a two-point discrimination was 20-30 mm. Linear scars were left in the flap donor sites, with no impact on squatting or striding. In vaginal examination, 1.5 to 2.0 fingers could be inserted in bilateral reconstruction cases, while 2.0 to 3.0 fingers could be inserted in unilateral reconstruction cases. The anus functioned well during defecation.

Is It Radiculopathy or Referred Pain? Buttock Pain in Spinal Stenosis Patients

BACKGROUND: Buttock pain is common, and there are no fixed guidelines for its diagnosis and treatment. This study compared a selective nerve root block and a facet joint block for patients with degenerative spinal disease and buttock pain. METHODS: Patients with degenerative spinal disease who presented with buttock pain, received a selective nerve root block (group A) or a facet joint block (group B) from June 2017 to September 2017, and were able to be followed up for more than 3 months were prospectively enrolled. Clinical results were assessed using a visual analog scale for comparative analysis. RESULTS: One day after the procedure, an excellent response was found in 7% and 6% of groups A and B, respectively; a good response was found in 41% and 13% of groups A and B, respectively. Two weeks later, an excellent response was found in 11% and 4% of groups A and B, respectively; a good response was found in 41% and 20% of groups A and B, respectively. Six weeks later, an excellent response was found in 11% and 7% of groups A and B, respectively, and a good response was found in 41% and 20% of groups A and B, respectively. At the final follow-up, more than 47% and 46% of patients showed a good response in groups A and B, respectively. In group A, the visual analog scale score improved compared to the pre-procedure value of 5.01 to 2.74 on day 1, 2.51 at week 2, 2.38 at week 6, and 2.39 at week 12. In group B, the visual analog scale score improved compared to the preprocedure value of 5.24 to 3.94 on day 1, 3.99 at week 2, 3.24 at week 6, and 2.59 at week 12. On day 1 and at weeks 2 and 6, group A showed a significantly better outcome than group B (p < 0.05). CONCLUSIONS: The selective nerve root block showed superior results up to 6 weeks post-procedure. Considering that the selective nerve root block is effective for treating radiculopathy, the primary cause of buttock pain can be thought to be radiculopathy rather than degenerative changes of the facet joint.

Classification of Hip Shape and Customized Hip Augmentation in Asian Women

BACKGROUND: We classified the hips of Korean women into 6 types based on shape and contour, and have performed gluteal augmentation using Elastomere implants with lipoplasty of the flank, gluteal fold, and saddle bags of the thigh according to the hip type. METHODS: We analyzed the shapes and contour of the buttocks of 148 patients from September 2009 to September 2015. We performed buttock augmentation with implants using Gonzalez's XYZ method, as well as liposuction and fat injection lipoplasty of the surrounding areas in these 148 patients. RESULTS: We defined the following 6 types: the oval type (30%), the straight type (17%), the peach type (9%), the trapezoid type (20%), the heart type (11%), and the W type (13%). Ninety-seven patients underwent hip augmentation with an implant only or combined with lipoplasty, and 51 patients underwent lipoplasty for buttock shape correction. Patients were followed up for at least 3 months, with the longest follow-up being 4 years. Implants were removed postoperatively in 8 of 97 cases. CONCLUSIONS: The hip augmentation not only involves the simple insertion of implants, but also complex surgical procedures on the surrounding flank and thigh areas. Appropriate procedures should be utilized based on the 6 different hip types to ensure the best outcomes.

Analysis of gluteal subcutaneous and muscle thickness in infants and children for application to intramuscular injection, autologous fat grafting, and gluteal artery perforator flaps

BACKGROUND: To achieve improvements in intramuscular injection, autologous fat grafting, and gluteal artery perforator flaps in infants and children, the relationships of computed tomography (CT)-determined gluteal muscle thickness (MT) and subcutaneous tissue thickness (SCT) with age and body mass index (BMI) were analyzed. METHODS: Gluteal SCT and MT at ventrogluteal (VG) and dorsogluteal (DG) sites were measured in a standardized manner in 350 patients aged 0 to 6 years who had visited a tertiary hospital and had undergone abdominopelvic CT between January 2005 and December 2016. Recorded measurements were analyzed using one-way analysis of variance and stepwise multiple regression to identify the factors that were most closely related to MT and SCT. RESULTS: Subcutaneous tissue at VG sites was thinner than at DG sites, but not significantly so in any age group. Muscles tended to be thinner at VG sites in 4 to 7-year-old, but thicker at VG sites in 1 to 3-year-old, though the differences were not significant. MT in the VG and DG regions was found to be related to age, and SCT in these regions to be related to age and BMI. CONCLUSIONS: The VG and DG sites should be considered as alternatives for intramuscular injection in infants and children when the anterolateral site is problematic. In addition, considering the gluteal MT and SCT of infants and children should help produce good results in autologous fat grafting and gluteal artery perforator flap harvesting.

INTRODUCTION: Since the introduction of highly active antiretroviral therapy for the treatment of human immunodeficiency virus (HIV), disease mortality has been dramatically reduced worldwide. One related side effect from the use of these drugs is gluteal lipodystrophy. The aim of this study is to assess the quality-of-life impact of correcting this deformity in HIV patients. METHODS: A historical cohort study was conducted between January 2010 and December 2014 with 23 patients, assessing the quality of their lives using the Nottingham Health Profile. A statistical analysis was performed using the McNemar test for related samples. RESULTS: There was a significant difference between preoperative and postoperative response in 19 of the 38 questions. CONCLUSION: We may say that gluteal reconstruction plays a role in improving quality of life for HIV patients who have been affected by antiretroviral related gluteal lipodystrophy.

Curative effect of stomatitis spray combined with 3M liquid dressing on degree II red buttocks in infants / 现代临床护理

Objective To explore the curative effect of stomatitis spray combined with 3M liquid dressing on degree II red buttocks in infants and summarize key points of nursing care. Methods From April 2012 to June 2016, 64 infants with degree II red buttocks were treated in our department. According to the admission time, the infants were divided into control and experiment groups in equal number. The control group was treated with zinc oxide ointment, and the experiment group with stomatitis spray combined with 3M liquid dressing. The curative effect, total effective rate, and wound healing time were compared after treatment between the groups. Results The curative effect and total effective rate of red buttocks in the experiment group were significantly better than those of the control group (P<0.05). Moreover, the wound healing time in the experiment group was obviously shorter than that of the control (P<0.05). Conclusions Compared to zinc oxide ointment, the stomatitis spray combined with and 3M liquid dressing is more effective in the treatment of severe red buttocks of the infants. Moreover, the latter is advantageous in wound healing time, compliance, treatment, and curative effect, which indicates its potential application in clinic.

Aplicação de ácido poli-l-lático para o tratamento da flacidez corporal / Poly-L-lactic acid injections in sagging body skin

Introdução: O tratamento da flacidez cutânea corporal constitui grande desafio, pois poucos são os procedimentos destinados a melhorá-la. O ácido poli-L-lático é polímero sintético injetável da família dos alfa-hidroxiácidos, cuja injeção na derme profunda ou hipoderme superficial induz reação local e gradual, com síntese de novo colágeno pelos fibroblastos e consequente aumento da espessura dérmica. Objetivo: Avaliar os efeitos do ácido poli-L-lático na flacidez da pele do corpo. Métodos: Quatorze pacientes que apresentavam flacidez de região glútea foram tratadas com duas aplicações de ácido poli-L-lático com intervalos de 45 dias entre elas. Foram realizadas avalição clínica inicial e seis meses após a segunda aplicação, fotos prévias e seis meses após o tratamento, bem como foram aplicados questionários às pacientes e ao médico avaliador, e realizado exame ultrassonográfico de todas as pacientes para verificação do aumento de espessura dérmica. Foram avaliados também os efeitos adversos observados. Resultados: Na opinião das pacientes, 85% apresentaram melhora no aspecto geral da pele e 71% na flacidez. Para o médico avaliador, 100% das pacientes apresentaram melhora no aspecto geral da pele e na flacidez, porém em graus variáveis e não proporcionais ao grau de gravidade inicial. Onze pacientes tiveram aumento da espessura dérmica acima de 20% dos pontos. Não houve efeitos colaterais importantes no período avaliado. Conclusões: Os resultados são promissores e devem ser confirmados com a realização de estudos com casuística maior.

Introduction: The treatment of sagging skin in body areas is still a big challenge, as there are few aesthetic procedures aiming to improve it. The poly-L-lactic acid (PLLA) is an injectable synthetic polymer of the alpha-hydroxy acids family, which injection into the deep dermis or superficial hypodermis induces a local and gradual reaction, with synthesis of new collagen by the fibroblasts and consequent increase of dermal thickness. Purpose: Evaluate the effects of poly-L-lactic acid on the sagging skin of the body. Methods: Fourteen patients with sagging in gluteal region underwent two applications of poly-L-lactic acid with a 45 days interval between them. We performed an initial clinical evaluation and after six months of the second application, photos before and after six months of treatment, questionnaires answered by the patient and by the evaluating physician and ultrasound examination of all patients to assess the increase of dermal thickness. The adverse effects observed were also evaluated. Results: In patient's opinion, 85% presented improvement of general appearance of the skin and 71% noticed improvement of sagging. For the evaluating physician, 100% of patients presented improvement of general appearance of the skin and improvement of sagging, but in different degrees and not proportional to the initial degree of severity. There was no significant side effects in the period evaluated. Conclusions: The results are promising and should be confirmed with studies with a larger sample size.

Porokeratosis ptychotropica: a rare manifestation with typical histological exam

Abstract: Porokeratosis is a disorder of epidermal keratinization characterized clinically by a distinctive ridge-like border, and histologically by cornoid lamellae. The known clinical variants of porokeratosis are: classic porokeratosis of Mibelli, disseminated superficial (actinic) porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata, linear porokeratosis and punctate porokeratosis. In 1995, a seventh form was described as porokeratosis ptychotropica: a verrucous form resembling psoriasis involving the gluteal cleft presenting on the histological exam multiple cornoid lamellae. There are very few reports in the literature of this clinical variant. The present study describes the case of a healthy male presenting gluteal hyperkeratotic plaques for 22 years. He had been to several dermatologists, none of them had achieved a definitive diagnosis. We present a typical clinical presentation and its dermoscopy findings, in addition to histological examination that confirmed the diagnosis.

The Adipofascial V-Y Advancement Flap with Skin Graft for Coverage of the Full-Thickness Burns of the Gluteal Region

Any types of burn injury that involve more than deep dermis often require reconstructive treatment. In gluteal region, V-Y fasciocutaneous advancement flap is frequently used to cover the defect. However, in case of large burn wounds, this kind of flap cannot provide adequate coverage because of the lack of normal surrounding tissues. We suggest V-Y adipofascial flap using the surrounding superficially damaged tissue. We present the case of a patient who was referred for full-thickness burn on gluteal region. We performed serial debridement and applied vacuum-assisted closure device to defective area as wound preparation for coverage. When healthy granulation tissue grew adequately, we covered the defect with surrounding V-Y adipofascial flap and the raw surface of the flap was then covered with split-thickness skin graft. We think the use of subcutaneous fat as an adipofascial flap to cover the deeper defect adjacent to the flap is an excellent alternative especially in huge defect with uneven depth varying from subcutaneous fat to bone exposure in terms of minimal donor site morbidity and reliability of the flap. Even if the flap was not intact, it was reuse of the adjacent tissue of the injured area, so it is relatively safe and applicable.

Anterograde pedicled anterolateral thigh flaps for treatment of complicated hip decubitus / 中华创伤杂志

Objective To investigate the methods and effects of anterolateral thigh flap reconstruction of the complicated hip decubitus.Methods The study contained 24 cases of grade Ⅳ hip decubitus reconstructed with anterograde pedicled anterolateral thigh flaps through May 2010 to July 2014.There were 13 males and 11 females,aged 26-64 years (mean 54 years).Defects ranged in size from 12 cm×6 cm to 24 cm× 12 cm.Dimensions of flaps harvested were 14 cm ×8 cm to 30 cm× 14 cm.Eighteen cases of the donor sites were directly sutured and six covered with full thickness skin.Results Twenty-two flaps survived completely,and wound was healed by the first intension.Two flaps developed partial distal necrosis,and wound was healed after dressing treatment.Period of follow-up was 6 months to 2 years.Shape,texture and color of the flaps were well matched with the recipient area.Conclusion The anterolateral thigh flap transplantation has advantages of similarity to the recipient area,large enough flap area and sound expected effective and is a good method for repair of hip decubitus.
