Brow rhytidectomy with or without Stades-like procedure for correction of pseudoptosis and trichiasis-entropion of the upper eyelid in Chow Chow and Shar-Pei dogs: A retrospective study of 27 dogs (2019-2022).

PURPOSE: Heavy brows in Chow Chow and Shar-Pei dogs can be associated with pseudoptosis and trichiasis-entropion of the upper eyelids, causing vision impairment and ocular discomfort. This study describes the outcomes of brow rhytidectomy ± Stades-like procedure to address these anatomical abnormalities. METHODS: Retrospective medical records review (2019-2022). RESULTS: Twenty-seven dogs (n = 15 Chow Chow, n = 12 Shar-Peis) were included, aged 1.9 ± 1.5 years (0.5-6.5 years). Presenting complaints included recurrent episodes of ocular inflammation (n = 13, 48.1%), blepharospasm (n = 10, 37.0%), corneal ulcers (n = 8, 29.6%), entropion (n = 6, 22.2%), and impaired vision (n = 4, 14.8%). Brow skin was removed as follows: (i) First incision parallel and 10-15 mm dorsal to upper lid, slightly extending beyond medial/lateral canthi; (ii) second incision forming an arc with its apex 15-35 mm dorsal to the first incision; and (iii) standard two or three layers closure. In 22/27 dogs, a Stades-like procedure was performed by removing a 2-4 mm strip of skin above eyelid margin and leaving it to heal by secondary intention (no sutures). At last recheck (follow-up 354.5 ± 187.8 days), 19/27 dogs (70.4%) had an adequate eyelid conformation, 7/27 dogs (25.9%) were considered under-corrected, and 1/27 dogs (3.7%) was over-corrected. Most owners (81.5%) were satisfied with the surgical results. Most cases (96.3%) had no recurrence of the clinical signs during the entire follow-up period. CONCLUSIONS: Brow rhytidectomy ± Stades-like procedure provide good cosmetic and clinical outcomes in Chow Chow and Shar-Pei dogs, although under correction may occur in severely affected dogs and with advancing time.

Case report: Radiofrequency-induced thermal burn injury in a dog after magnetic resonance imaging.

A 10-year-old male Shar-Pei was referred for lethargy and proprioceptive deficits of the left thoracic limb. An magnetic resonance imaging (MRI) examination of the cervical spinal column and the brain was performed. The MRI examination of the brain was normal. A left-sided C3-C4 intervertebral disc extrusion with spinal cord compression was diagnosed. Medical treatment was elected. Within a week after the MRI examination, the dog presented with deep partial-thickness skin burn wounds in both axillae. Since the specific absorption rate had not exceeded the safety limits during any of the scans and no other procedures or circumstances were identified that could possibly have resulted in burn injuries, the thermal burn injuries were diagnosed as radiofrequency (RF) burns. The wounds healed by secondary intent over the next month. RF burns are the most reported complication in humans undergoing MRI but have not been reported in veterinary patients. Clinicians and technicians should consider the potential risk for RF burns in veterinary patients and take precautions regarding positioning of the patient and take notice of any signs of burn injury when performing follow-up examinations.

Dermatological Problems of Brachycephalic Dogs.

Brachycephalic dogs are not only affected by brachycephalic obstructive airway syndrome (BOAS), but are also frequently referred to veterinary dermatologists for skin conditions, with English bulldogs and pugs particularly over-represented. Some skin diseases, such as skin fold dermatitis, are directly associated with the abnormal anatomic conformation of brachycephalic dogs, while for others, such as atopic dermatitis and viral pigmented plaques, there is an underlying genetic basis or a general predisposition. Anatomic alterations associated with brachycephaly, leading to fold formation of the skin and stenosis of the ear canal, together with primary immunodeficiencies described in some breeds, favor the development of pyoderma, Malassezia dermatitis, and otitis externa/media. In addition, the frequently neglected but often lifelong dermatological problems of brachycephalic dogs are an important consideration when discussing genetic and medical conditions affecting the welfare of those dogs. Here we review the current state of knowledge concerning dermatological problems in brachycephalic dogs and combine it with clinical experience in the management of these challenging disorders.

Pseudo-Pneumothorax Due to Skin Folds in a Patient With Pneumonia.

Pseudo-pneumothorax refers to several conditions that can mimic pneumothorax on chest radiography, leading to diagnostic uncertainty and unnecessary interventions. These include skin folds, bed sheet folds, clothes, scapular borders, pleural cysts, and elevated hemidiaphragm. We report a case of a 64-year-old patient with pneumonia whose chest radiograph revealed, in addition to the typical pneumonia findings, what appeared similar to bilateral pleural lines raising the suspicion of bilateral pneumothorax, but this finding was not supported clinically. Careful reexamination and further imaging ruled out the possibility of pneumothorax and concluded that this was the result of artifacts produced by skin folds. The patient was admitted and received intravenous antibiotics and was discharged three days later in stable condition. Our case highlights the importance of careful examination of imaging findings before unnecessarily proceeding to tube thoracostomy, especially when the clinical suspicion of pneumothorax is low.

Neonatal diagnosis of circumferential skin creases.

BACKGROUND: Circumferential skin creases is a rare and heterogeneous disorder characterized by multiple and redundant skin folds, which can present as an isolated feature or in association with other phenotypic anomalies. Here, we report the case of a newborn who immediately captured our attention because of his phenotype. CASE: A male Caucasian infant was born at 39 weeks and 4 days of gestational age with an instrumental delivery, after a pregnancy characterized by threat of preterm birth at 32 weeks. Fetal ultrasounds were reported to be normal. The patient was the first child of non-consanguineous parents. Anthropometry at birth: weight 3.590 kg (0.57 SDS); length 53 cm (1.73 SDS); cranial circumference 35.5 cm (0.83 SDS). Clinical examination soon after birth revealed multiple, asymmetric and deep skin folds involving forearms, legs and lower eyelids (right > left). These folds seemed not to cause any physical discomfort. In addition, hypertrichosis, micrognathia, low-set ears and a thin, down-turned border of upper lip were observed. Cardio-respiratory, abdominal and neurological examination was unremarkable. There was no family history of similar appearance or other physical abnormalities. Given the clinical picture, an array-CGH was performed, which was normal. A genetic counseling was requested and Circumferential Skin Creases disorder was diagnosed based on the typical cutaneous involvement and, given the absence of other clinical signs, it was supposed a benign evolution, with skin folds tending to disappear over time. In addition, the baby's DNA was requested for a targeted genetic analysis, which resulted negative. CONCLUSIONS: This clinical case underlines the need of performing a detailed neonatal physical examination in order to realize a timely diagnostic approach. Our patient presented with multiple skin folds, facial dysmorphism but normal systemic and neurological examination. Anyways, since Circumferential Skin Creases may be associated with later neurological symptoms, a regular reevaluation is recommended.

The Effect of Dietary Intake and Nutritional Status on Anthropometric Development and Systemic Inflammation: An Observational Study.

(1) Background: Daily caloric intake should aim to reduce the risk of obesity or poor anthropometric development. Our study objective was to analyze the association between food consumption, inflammatory status and anthropometric development; (2) Methods: We performed a prospective observational analytical research during September 2020 and April 2021 on a group of 160 healthy subjects, aged between 6 and 12 years old, by analyzing food ingestion, the basal metabolic rate, anthropometric development and the inflammatory status; (3) Results: IL-6 was significantly correlated to the sum of skinfolds, along with both serum proteins and triglycerides. The skin folds were significantly correlated with the caloric intake and with total fat intake, next to saturated and trans fats. Unlike the skin folds, the body weight was significantly correlated with the caloric intake along with some vitamins, such as Vitamin A and Vitamin B12. Inactive mass increased with excessive folic acid, Vitamin E, Vitamin K and saturated fat intake; (4) Conclusions: The inflammatory status was influenced by the ingestion of micronutrients, total serum lipids and proteins. The anthropometric development was associated with the ingestion of carbohydrates, energy balance and energy intake. We can conclude that daily menu and nutrition imbalances can influence both the risk of obesity and the inflammatory status.

Michelin Tire Baby Syndrome: A Rare Case with Review of Literature.

Michelin tire baby syndrome (MTBS) is a benign hamartomatous condition with ring-like lesions present on the limbs and trunk. MTBS is a rare genodermatosis. According to our search, only 20 cases have been reported. We present a case of a six-month-old female child, with complaints of fever and seizures. Since birth, she had asymptomatic multiple, asymmetric skin folds on all four limbs, resembling "Michelin Man" logo of the French tire manufacturer. She had microcephaly with characteristic round face hypertelorism, depressed nasal bridge, hypertrichosis with low set ears, a thin down-turned vermillion border of the upper lip, and a short neck. MRI was normal. Clinically, the diagnosis of MTBS was made. In addition, the parents were counseled about the self-limiting course of this disorder. MTBS itself might not be a single disorder but may manifest as a clinical finding associated with other disorders; therefore, a regular follow up of these patients is usually advised.

Masa grasa corporal en escolares y adolescentes en la zona de la Tamborada Cochabamba, Bolivia / Mass body fat in schoolchildren and adolescents in the area of the Tamborada Cochabamba, Bolivia

Objetivo: determinar la proporción de masa grasa corporal cuantificada con pliegues subcutáneos en escolares y adolescentes de la zona de Tamborada de Cochabamba. Metodos: estudio descriptivo y transversal. Se evaluaron a 158 escolares y adolescentes de ambos sexos entre 7 a 17 años de edad, que asisten a guarderías y centros de apoyo escolar dependientes del Centro de Desarrollo Integral (CDI). Se evaluó el IMC según edad y sexo. Para el estudio de la distribución grasa corporal, se midieron los cuatro pliegues cutáneos, pliegue tricipital, bicipital, subescapular y suprailíaco, a partir de las ecuaciones de regresión múltiple de Brook y Siri, se obtuvo la densidad y con ello el volumen total de grasa corporal de cada sujeto. Resultados: para el indicador antropométrico IMC no se encontraron diferencias estadísticamente significativas para la variable sexo (p = 0,165). la masa grasa corporal en porcentaje (%); en el género masculino se puede observar que ésta aumenta progresivamente hasta los 12 años y posteriormente disminuye también progresivamente. En el caso de las mujeres desde el inicio se evidencia un ascenso hasta los 13 años, para luego descender en el porcentaje de masa grasa corporal. la asociación entre los valores del porcentaje de grasa corporal y las cifras del índice de masa corporal, hay una correlación muy alta entre ambas variables (r = 0,861; p < 0,001). Discusión y Conclusión: estos datos indican que el índice de masa corporal se incrementa entre los sujetos y las cifras de porcentaje de grasa mostraron un incremento en modo paralelo.

Objective: to determine the proportion of body fat mass quantified with subcutaneous folds in school children and adolescents in the area of "La Tamborada", Cochabamba. Methods: it is a descriptive and transversal study. A total of 158 schoolchildren and adolescents from both sexes and between 7 and 17 years of age that attend day care centers and school support centers under the Integral Development Center (CDI) were evaluated. BMI was assessed by age and sex. For the study of the body fat distribution, the four skinfolds, triceps, bicipital, subscapular and suprailiac fold were measured from Brook's and Siri multiple regression equations, the density was obtained and thus the total volume of Body fat of each subject. Results: for the anthropometric indicator BMI no statistically significant differences were found for the gender variable (p = 0.165). Body fat mass in percentage (%); in the masculine gender it is possible to be observed that this increases progressively until the 12 years and later also diminishes progressively. In the case of women from the beginning, an ascent up to the age of 13 is evident, in order to decrease the percentage of body fat. The association between body fat percentage values and body mass index values, there is a very high correlation between both variables (r = 0.861, p <0.001). Discussion and Conclusion: these data indicate that body mass index is increased between subjects and fat percentage figures showed an increase in parallel mode.

Segmental neurofibromatosis presenting with congenital excessive skin folds.

Segmental neurofibromatosis (SNF) is a rare type of neurofibromatosis (NF-1) resulting from post-zygotic somatic mutations in the neurofibromin gene that leads to mosaicism. Reported manifestations of SNF include neurofibromas, freckling, or café-au-lait spots limited to a single body region or limb. We present a 5-month-old male referred to our clinic for evaluation of congenital excessive skin folds on the back. A mildly erythematous, poorly demarcated soft plaque was noted, consisting of excessive skin folds. A cluster of light brown hyperpigmented macules was seen overlying the plaque. A punch biopsy of the plaque confirmed a diagnosis of neurofibroma. Further investigation ruled out other manifestations of NF-1. The early onset of our patient's neurofibroma and its gross appearance with redundant skin folds are all unusual features. To our knowledge, congenital excessive skin folds found in a single tumor have not been previously described in the literature as a manifestation of SNF. Clinicians should be educated about the possibility of congenital localized skin folds in association with SNF in order to identify the disease in infancy and monitor any changes in neurofibroma pathology.

Reference curves of the body fat index in adolescents and their association with anthropometric variables / Curvas de referência do índice de adiposidade corporal de adolescentes e sua relação com variáveis antropométricas

OBJECTIVES: To develop reference curves for the body fat index (BFI) in the pediatric population, in adolescents from the city of São Paulo, Brazil, and verify their association with body mass index and body fat percentage. METHODS: The study is part of the research project "Nutritional Profile of Adolescents from Public and Private Schools of São Paulo" that was performed in 2004-2005. A total of 4,686 adolescents (2,130 boys and 2,556 girls) aged 10-15 years were divided into two groups: 10-12 and 13-15 years of age. Body mass, height, body mass index, hip circumference, body fat percentage, body fat index, and sexual maturation performed by the self-assessment method (prepubertal, pubertal, and postpubertal) were analyzed. ANOVA was performed, as well as percentile distribution, Pearson's correlation, and Bland-Altman plot. RESULTS: In boys, there was an increase in body mass, height, body mass index, and hip circumference with advancing age and Tanner stage. In girls, there was an increase in body fat index and body fat percentage with advancing age and stage of sexual maturation. An association was found between body fat index and body mass index (r = 0.67 in boys and 0.80 in girls, p < 0.001) and body fat percentage (r = 0.71 in boys and 0.68 in girls, p < 0.001). CONCLUSION: The body fat index seems to reflect well the phenomena of sexual dimorphism in adolescence, is easy to perform, and represents a method that should be used in population samples. .

OBJETIVOS: Desenvolver curvas de referência do índice de adiposidade corporal para população pediátrica, em adolescentes da cidade de São Paulo, Brasil, e verificar a sua relação com o índice de massa corporal e percentual de gordura corporal. MÉTODOS: O estudo faz parte do projeto de pesquisa "Perfil Nutricional de Adolescentes de escolas Públicas e Privadas de São Paulo" realizado em 2004/2005. 4.686 adolescentes (2.130 meninos e 2.556 meninas) de 10-15 anos foram divididos em dois grupos: 10-12 e 13-15 anos. Massa corporal, estatura, índice de massa corporal, circunferência de quadril, porcentagem de gordura corporal, índice de adiposidade corporal e maturação sexual realizada pelo método de autoavaliação (pré-púbere, púbere e pós-púbere) foram analisadas. Foi feito ANOVA, distribuição percentilar, correlação de Pearson e o gráfico de Bland-Altman. RESULTADOS: Nos meninos, ocorreu aumento da massa corporal, estatura, índice de massa corporal e circunferência do quadril com o avanço da idade e estágio de Tanner. Nas meninas, ocorreu aumento do índice de adiposidade corporal e do percentual de gordura corporal com o avanço da idade e estágio de maturação. Foi encontrada uma associação entre o índice de adiposidade corporal com o índice de massa corporal (r = 0,67 nos meninos e 0,80 nas meninas; p < 0,001) e com o percentual de gordura (r = 0,71 nos meninos e 0,68 nas meninas; p < 0,001). CONCLUSÃO: O índice de adiposidade corporal parece refletir bem os fenômenos do dismorfismo sexual na adolescência, sendo um método de fácil realização que deveria ser mais utilizado em amostras populacionais. .

Predictor variables for a half marathon race time in recreational male runners.

The aim of this study was to investigate predictor variables of anthropometry, training, and previous experience in order to predict a half marathon race time for future novice recreational male half marathoners. Eighty-four male finishers in the 'Half Marathon Basel' completed the race distance within (mean and standard deviation, SD) 103.9 (16.5) min, running at a speed of 12.7 (1.9) km/h. After multivariate analysis of the anthropometric characteristics, body mass index (r = 0.56), suprailiacal (r = 0.36) and medial calf skin fold (r = 0.53) were related to race time. For the variables of training and previous experience, speed in running of the training sessions (r = -0.54) were associated with race time. After multivariate analysis of both the significant anthropometric and training variables, body mass index (P = 0.0150) and speed in running during training (P = 0.0045) were related to race time. Race time in a half marathon might be partially predicted by the following equation (r(2) = 0.44): Race time (min) = 72.91 + 3.045 * (body mass index, kg/m(2)) -3.884 * (speed in running during training, km/h) for recreational male runners. To conclude, variables of both anthropometry and training were related to half marathon race time in recreational male half marathoners and cannot be reduced to one single predictor variable.

Gordura corporal de pacientes em hemodiálise / Body fat of hemodialysis patients

Objetivo. Avaliar a gordura corpórea de pacientes em hemodiálise por bioimpedância elétrica e dobras cutâneas, a correlação entre os dois métodos e destes com o índice de massa corpórea. Métodos. Estudo transversal com 38 pacientes adultos em hemodiálise no Hospital das Clínicas da Universidade Federal de Goiás. Calculou-se o índice de massa corpórea: peso (kg)/altura (m2). Utilizaram-se bioimpedância elétrica e dobras cutâneas - triciptal, biciptal, subescapular e suprailíaca - para estimar a gordura corporal. Utilizaram-se estatística descritiva, coeficiente de correlação de Pearson e teste t de Student, sendo consideradas significativas diferenças no nível de p < 0,05. Resultados. A média do índice de massa corpórea indicou eutrofia nos dois sexos. As mulheres apresentaram percentual de gordura de 35,4% pelas dobras cutâneas e 39,3% pela bioimpedância elétrica. Nos homens, o percentual de gordura pelas dobras cutâneas foi 23,1% e 26,8% pela análise de bioimpedância elétrica. A média da gordura estimada por bioimpedância elétrica e dobras cutâneas não apresentou diferença estatisticamente significante nos dois sexos, todos p > 0,05. A gordura corporal apresentou correlação positiva entre a bioimpedância elétrica e as dobras cutâneas com r = 0,81 nos homens e r = 0,96 nas mulheres. Verificou-se forte correlação entre o índice de massa corpórea e os dois métodos em ambos os sexos. Conclusão. As mulheres apresentaram excesso de gordura corporal pelos dois métodos. Apesar de os homens terem percentual de gordura ligeiramente elevado apenas pela bioimpedância elétrica, não houve diferença estatisticamente significante entre os métodos. A forte correlação entre os métodos, e destes com o índice de massa corpórea, sugere que ambos são úteis e confiáveis para a avaliação da gordura corporal e acompanhamento nutricional de pacientes em hemodiálise.

Objective. To evaluate the body fat of hemodialysis patients by electrical bioimpedance and skin folds, the correlation between the two methods and those with body mass index.Methods. Cross-sectional study with 38 adult patients on hemodialysis in the Hospital of the Federal University ofGoiás. The body mass index was calculated: weight (kg)/height (m2); electrical bioimpedance and skin folds (triciptal, biciptal, subscapular and suprailiac) were used to estimate the body fat. We used descriptive statistics, Pearson correlation coefficient (r) and Student t test, considering significant differences in the level of p < 0.05.Results. The mean body mass index for both sexes indicated normal range. Women had 35.4% fat by skin foldsand 39.3% by electrical bioimpedance. Men presented 23.1% of fat by skin folds and 26.8% by electrical bioimpedance. The average fat estimated by electrical bioimpedance and skin folds was not statistically significant among both sexes, p > 0.05. The body fat showed a positive correlation between electrical bioimpedance and skin folds, withr = 0.81 in men and r = 0.96 in women. There was strong correlation between body mass index and the two methodsamong both sexes. Conclusion. Women showed an excess of body fat by the two methods. Although men show slightly higher percentage of fat just by electrical bioimpedance, there was no statistically significant difference between the methods. The strong correlation between the methods, and those with body mass index, suggest that both are useful and reliablefor the assessment of body fat and nutritional monitoring of hemodialysis patients.

Mediciones antropométricas en el neonato / Anthropometric assessment in newborns

La vigilancia del crecimiento en el neonato, a través de la evaluación antropométrica, reviste gran importancia en términos de detección de riesgos de morbi-mortalidad y deterioro del estado nutricio, permitiendo la toma de decisiones oportunas y convenientes. Para que el control de calidad en la evaluación antropométrica esté garantizado, se requiere conocer las técnicas de mediciones correctas, estar estandarizado y comparar con valores de referencia de una población similar. Las mediciones antropométricas más utilizadas en el neonato hospitalizado incluyen: peso corporal (masa corporal total), longitud (tamaño corporal y óseo), medición de circunferencias (brazo, tórax, muslo) y pliegues cutáneos (grasa subcutánea). Además, al combinar algunas mediciones, se pueden generar índices pronósticos nutricios y de utilidad diagnóstica. La antropometría debe ser un método de rutina en las unidades de cuidado neonatal como parte de una evaluación nutricia completa.

Anthropometric assessment in newborns is a very useful tool to assess growth and identify nutritional risk, in order to design and implement an adequate nutrition care plan. Anthropometry helps estimate total body mass, fat mass and fat free mass through measures of the body.The most useful anthropometric measurements in the hospitalized newborn include: weight (total body mass), length (body and bone size), circumferences (head, mid arm, thorax, and thigh) and skin folds (subcutaneous fat). To assure quality in anthropometric measurements it is essential to know the correct technique, to be standardized and use reference values from a similar population. The combination of 2 different measurements may provide useful prognostic and diagnostic nutritional indexes. Anthropometry should be including in any neonatal unit as part of a complete nutritional assessment of this population.
