Asymmetrical thigh creases or isolated thigh crease may be a false positive sign with low predictive value in the diagnosis of developmental dysplasia of the hip in infants: a prospective cohort study of 117 patients.

BACKGROUND: The clinical importance of asymmetrical thigh creases in the diagnosis of developmental dysplasia of the hip (DDH) in infants remains controversial. The aim of this study is to investigate the association of asymmetrical skinfolds of the thigh as the only clinical finding with the DDH in infants. METHODS: One hundred and thirty-four infants between January 2010 and December 2015 were referred to our clinics for DDH with the only clinical sign being asymmetrical or isolated thigh creases and met the inclusion criteria of the study. Patients with another clinical sign for DDH in our initial evaluation, those infants suspicious for syndrome and those older than 6 months were excluded. Finally, 117 patients had undergone clinical and ultrasound evaluation and were included to statistical analysis. RESULTS: There were 82 females and 35 males, with mean age of 2.2 months old. In 96 of the 117 infants (82.1%), there were provocative skin creases in the opposite thigh after a little pressure of the thigh by the examiner during the evaluation. Three of the babies (3.1%) with provocative skin creases and 1 (4.8%) with true isolated thigh crease had immature hips in ultrasonography. Positive predictive value for DDH of an isolated or asymmetrical thigh crease was 4.55% (95% CI 0.83-21.36%), and negative predictive value was 96.97% (95% CI 94.75-98.27%). Sensitivity of skinfold asymmetry found to be 25% (95% CI 0.63-80.59%), and specificity was 82.05% (95% CI 73.88-88.53%) for DDH. CONCLUSION: The positive predictive value of asymmetrical or isolated thigh creases for DDH in infants was found to be low, as the majority of hips with normal clinical examination and asymmetry in thigh skinfolds seemed to be normal. Moreover, in-depth evaluation of the patients could highlight new provocative thigh creases in the opposite thigh, which could limit the referrals to expert physicians to exclude DDH. LEVEL OF EVIDENCE: Level III.

Fat infiltration in the gluteus minimus muscle in older adults.

PURPOSE: Fat infiltration (FI) in the gluteus minimus muscle (GMin) has been reported as being restricted to the anterior part. The aim of this study was to verify whether FI is localized only to the anterior part of the GMin through the dissection of large number of elderly cadavers and to clarify the underlying mechanism of FI localized to a specific region. MATERIALS AND METHODS: Thirty-eight hips from 20 embalmed elder cadavers were dissected for verification of FI localization. The samples of three regions - the fat infiltrated region of the anterior part (FI), the region without FI (non-FI), and the posterior region - were harvested from nine hips for the histological fiber type assessment. RESULTS: The FI area was distributed at 2.6°-38° from the anterior border within the anterior part, of which function is responsible for hip extension and internal rotation and is likely reduced by disuse following aging. The number of type I fibers was lowest in FI, followed by non-FI, while the number of type I fibers was highest in the posterior. Meanwhile, the number of type II fibers was equivalent across the three regions. Atrophic type II fibers were observed in overall samples of the three regions, and grouped atrophy, which is evidence of denervation, was observed in FI and non-FI samples. Type grouping, which suggests to be reinnervated, was found in the non-FI and posterior samples but very little in the FI samples. CONCLUSION: FI in the GMin in older adults restricted to deep within the anterior part is secondary to disuse and is strongly related to impaired denervation-reinnervation process.

Man with leg rash.

CLINICAL INTRODUCTION: A 51-year-old male presented to the ED with a rash to his left thigh (figure 1) with erythema, swelling and pain. He endorsed paraesthesias, pruritus, fevers, vomiting and diarrhoea. Initial vitals were unremarkable. He was well appearing with an 8×8 cm violaceous patch on his left medial thigh with vesicles, surrounding erythema and induration with a second, smaller lesion on the right thigh. Both rashes were extremely tender.emermed;34/10/686/F1F1F1Figure 1Erythematosus and vesicular rash in bilateral legs.A bedside ultrasound image of the rash was obtained (figure 2).emermed;34/10/686/F2F2F2Figure 2Bedside ultrasound of rash.

Isolated fetal lymphatic malformation of the thigh: prenatal diagnosis and follow-up

Fetal lymphatic malformation can be found in different parts of the fetal body. It occurs most frequently in the nuchal and axillary region and less frequently in the abdomen or inguinal areas. Lymphatic malformation has been associated with fetal aneuploidy, hydrops fetalis, structural malformations, and intrauterine fetal death. A 31-year-old gravida 3, para 2 woman was admitted to our hospital at 22 weeks of gestation (confirmed by ultrasonographic examination). The fetus was alive, and had a mass derived from the left inguinal region extending to the anterior left leg with fluid-filled cavities about 3-5 cm in size. There was no evidence of intra-abdominal extension of the mass. Amniocentesis was performed. Fetal magnetic resonance imaging revealed a left inguinal cystic mass, which extended to the left thigh. Antenatal follow-up was uneventful. The mother gave birth at term with a cesarean section. Postnatal clinical examination and imaging examination confirmed the diagnosis of lymphatic malformation. Fetal lymphatic malformation carries a high risk of aneuploidy and fetal malformations. Patients diagnosed with lymphatic malformation in antenatal follow-up should be assessed in terms of coexistent anomalies. Fetal karyotyping should be done and the fetus should be monitored for fetal hydrops.

Appendicitis Presenting As Cellulitis of the Right Leg.

BACKGROUND: Several infectious processes of intra-abdominal origin may atypically present as skin or soft tissue infections or abscess in the thigh. CASE REPORT: We describe the case of a 73-year-old woman who presented to the emergency department with the clinical picture of a skin infection of the right leg. The patient's condition deteriorated during medical treatment with intravenous antibiotics. Subsequent radiologic imaging revealed that the complaints were caused by a bulging retroperitoneal appendicular abscess along the iliopsoas muscle, although the patient experienced no abdominal symptoms. The patient recovered completely after surgical intervention. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Timely performance of anatomic imaging in patients with unexplained skin or soft tissue infections and thigh abscesses is important because these findings may be manifestations of an abdominal pathology. A correct diagnosis in the emergency department prohibits delays in treatment.

Incomplete duplication of a lower extremity (polymelia): a case report.

INTRODUCTION: Polymelia, or congenital duplication of a limb, is an extremely rare entity in humans, with few cases reported in the literature. CASE PRESENTATION: We present the case of a six-month-old Hispanic boy born with a lower limb bud on the left posterior thigh. CONCLUSION: The infant had a favorable outcome and evolution after surgical treatment of his supernumerary limb, with no after-effects or impairment whatsoever.

This neoplasm typicall y corresponds tonodules composed of polygonal epithelioid cells, clear, reminiscent of the notochord and a second population of eosinophilic cells arranged incords and nests separated by myxoid stroma with phenomena similar to cytoplasmic vacuolization the chordoma (physaliphorous type cells).

Scurvy in a child with autism: magnetic resonance imaging and pathological findings.

We present a case of scurvy in a 6-year-old boy with autism and an unbalanced diet. The patient was admitted with difficulties in walking. Magnetic resonance imaging findings of the thigh showed diffuse signal abnormality in the bone marrow, periosteum, and the femoral muscle. A biopsy specimen of the femur showed hematoma, proliferative fibroblasts, and few collagen fibers, which suggested a deficiency of vitamin C. Although recurrent periosteal hematoma may be suggestive of scurvy, this finding was subtle in the current case. It is important to be aware of this rare disease because it is easily cured with vitamin C supplementation.

Post-bariatric thighplasty: result assessment / Coxoplastias pós-cirurgia bariátrica: avaliação dos resultados

BACKGROUND: Patients who experience massive weight loss often require a thighplasty procedure to reduce excess skin and reshape thighs and lower body contour, improving movement, hygiene, posture, self-image, and quality of life. METHODS: After weight loss and stabilization of weight, eight patients in the postoperative period of gastric bypass were subjected to a thighplasty. Measurements of upper and lower circumferences of the thighplasty and thigh heights were obtained in the preoperative and postoperative periods of 60 and 180 days for comparison of volume change after the surgical procedure. RESULTS: The average volume reduction of each thigh at a postoperative period of 180 days was 1,135 cm³ or 1.135 liters. All patients had small areas of dehiscence along the scars on the medial thigh, and dressings were applied for healing by secondary intention. One (12.5 percent) patient had cysts in both thighs, confirmed by ultrasound, and required surgical intervention for resection and subsequent resolution. CONCLUSIONS: It was possible to demonstrate significant reduction in the volume of each thigh after plastic surgery for contour refitting. Patient satisfaction and complications associated with the procedures performed were also documented.

INTRODUÇÃO: Pacientes que apresentam perda maciça de peso muitas vezes precisam reduzir o excesso de pele e remodelar o contorno das coxas e parte inferior do corpo, melhorando os movimentos, higiene, postura, autoimagem e qualidade de vida. MÉTODO: Oito pacientes em pós-operatório de gastroplastia redutora, após perda e estabilização do peso, foram submetidas a coxoplastia. Medidas das circunferências superior e inferior e da altura das coxas foram obtidas em pré-operatório e pós-operatório de 60 dias e 180 dias, para comparação de alteração de volume consequente ao procedimento cirúrgico. RESULTADOS: A redução média de volume de cada coxa, aos 180 dias de pós-operatório, foi de 1.135 cm³ ou 1,135 litro. Todas as pacientes apresentaram pequenas deiscências ao longo das cicatrizes em face medial das coxas, sendo realizados curativos com cicatrização por segunda intenção. Uma (12,5 por cento) paciente apresentou cistos em ambas as coxas, confirmados por ultrassonografia, sendo necessária intervenção cirúrgica para ressecção e consequente resolução. CONCLUSÕES: Foi possível demonstrar redução significativa do volume de cada coxa após cirurgia plástica para readequação do contorno, além de documentar a satisfação das pacientes e as complicações associadas aos procedimentos realizados.

Nevo lipomatoso cutáneo superficial: presentación de dos casos / Superficial cutaneous lipomatous nevus: report of two cases

El nevo lipomatoso cutáneo superficial (NLCS) es una anomalía del desarrollo infrecuente, caracterizada por la presencia de tejido adiposo maduro ectópico en la dermis. Puede estar presente al nacer o aparecer en la infancia o adolescencia. Describimos dos casos de NLCS: el primero, un niño de 4 años con una placa hipertricótica en la nalga izquierda, presente desde el nacimiento y el segundo, una niña de 9 años con una placa de aspecto esclerodermiforme en el muslo izquierdo, de aparición en etapa preescolar.

Nevus lipomatosus cutaneous superficialis (NLCS) is a rare developmental anomally characterized by the presence of ectopic mature adipose tissue in the dermis. It may be present at birth, or appear at chilhood or adolescence. We describe two cases of NLCS: the firs one, a 4-year-old child that presented with an hypertrychotic plaque on his left buttock, present from birth and, the second one, a 9-year-old girl with a plaque of sclerodermiform appearance on her left leg, that arise before school time.

Thigh-leg skin tube pedicle and amniotic band syndrome.

We are reporting the case of a young infant presenting with a cutaneous tubular bridge running from the dorsal aspect of the middle third of the thigh to the middle third of the leg resulting in a permanent flexion position of the limb. This finding was associated with another related to the amniotic band syndrome. Surgical resection showed a tube formed exclusively by normal skin tissue. The case appears unique although related lesions have been reported in the literature.

Observation of a supernumerary hamstring muscle: a state of the art on its incidence and clinical relevance.

During routine anatomic dissection of the lower extremities of a 67-year-old male body, a supernumerary ishiocrural muscle was observed. This supernumerary muscle had similarities to a rare variant of the semimembranous muscle. On the left side it arose from the lateral dorsal side of the femur between the short head of the biceps femoris muscle and the origin of the adductor magnus muscle. It inserted on the medial condyle deep to the normal insertion of the semimembranous at the posterior aspect of the articular capsule. This muscle can be regarded either as a short deep semimembranous muscle (M. semimembranosus profondus) or as a short belly of a semitendinous biceps as known in birds. The muscle was situated closely to the vessels and nerves of the popliteal region. On the right side a similar but somewhat fainter muscle was observed whose origin emanated from the fascia of the adductor magnus muscle. The muscle probably has no major clinical importance but might be important to the surgeon who has to intervene in the popliteal region.
