Un protocolo específico de entrenamiento interválico de alta intensidad de wushu sanda mejora la condición física de atletas amateur: un estudio piloto
[ES] Objetivo: Investigar los efectos de añadir un protocolo específico de entrenamiento interválico de alta intensidad (HIIT) al entrenamiento habitual de condición física de atletas amateur de wushu sanda. Métodos: Estudio experimental, en el que 6 atletas amateur de wushu sanda de nivel regional (24.6±6.4 años, 1.70±0.1 m de altura y 71.3±7.3 kg de peso) se sometieron a un programa de entrenamiento de 2 sesiones/semana durante 4 semanas. El protocolo de HIIT estuvo compuesto de 3 rondas de 2 minutos con intervalos de 1 minuto entre ellas, simulando la duración de un combate. Cada ronda se dividió en 8 bloques de 15 segundos. Cada bloque estaba compuesto de5 segundos de actividades de alta intensidad, 5 segundos de actividades de baja intensidad y 5 segundos de pausa. Se utilizaron saltos con contra movimiento, sentadillas, saltos horizontales, test de aptitud aeróbica (TKDtest) y test de velocidad de patada (FSOK). Resultados: Los atletas presentaron aumentos de rendimiento en salto con contra movimiento (de 41±5.7 a 47.3±7.3 cm, p=0.007, g=0.88), salto horizontal (de 1.7±0.4 a 2.3±0.3cm,p=0.01, g=1.56) y en la prueba FSOK (de 19.8±1.7 a 23.0±2.5 patadas, p=0.003, g=1.38). La frecuencia cardíaca en reposo disminuyó (de 120±8.3 a 107±11.4 lpm, p=0.03, g=1.20) y el tiempo hasta el agotamiento aumentó (de 8.5±1.8 a 13.1±1.4 min, p=0.003, g=2.63), así como el número de patadas (de 187±55.3 a 368±39.8 patadas, p=0.001, g=3.46). Conclusión: A pesar del pequeño tamaño de la muestra, los grandes tamaños de efectos hallados respaldan la conclusión de que añadir un protocolo HIIT específico de wushu sanda a la rutina de entrenamiento de atletas amateur puede producir mejoras en el rendimiento neuromuscular, aeróbico y anaeróbico.[EN] Objective: To investigate the effects of the addition of a specific high-intensity intermittent training (HIIT) protocol to the habitual training on the physical fitness of amateur wushu sanda athletes. Methods: This is an experimental study in which 6 amateur regional level wushu sanda athletes (24.6±6.4 yrs, 1.70±0.1m height, and 71.3±7.3kg weight) underwent a 2 session/week training program for 4 weeks. The HIIT specific protocol was composed of 3 rounds of 2 minutes with 1-minute intervals in between, simulating a match duration. Each round was divided into 8 blocks of 15 seconds. Each block was composed of 5 seconds of high-intensity activities, 5 seconds of low-intensity activities and 5 seconds of pause. Countermovement jump, squat jump, horizontal jump, aerobic fitness (TKDtest) and kick speed test (FSOK) were applied.Results: Athletes presented performance increases in countermovement jump (from 41±5.7 to 47.3±7.3cm, p=0.007, g=0.88), horizontal jump (from 1.7±0.4 to 2.3±0.3cm, p=0.01, g=1.56) and in the FSOK test (from 19.8±1.7 to 23.0±2.5 kicks, p=0.003, g=1.38). The resting heart rate decreased (from 120±8.3 to 107±11.4 bpm, p=0.03, g=1.20) and the time to exhaustion increased (from 8.5±1.8 to 13.1±1.4 min, p=0.003, g=2.63), as well as the number of kicks (from 187±55.3 to 368±39.8 kicks, p=0.001, g=3.46).Conclusion:Despite the small sample size, the large effect sizes found support the conclusion thatthe addition of a specific HIIT wushu sanda protocol to amateur athletes' training routine can lead to neuromuscular, aerobic and anaerobic performance improvements.[PT] Objetivo: Investigar os efeitos da adição de um protocolo específico de treinamento intermitente de alta intensidade (HIIT) ao treinamento habitual de wushu sanda na aptidão física de atletas amadores. Métodos: Estudo experimental em que 6 atletas amadores de nível regional de wushu sanda (24,6±6,4 anos, 1,70±0,1 m de estatura e 71,3±7,3kg de massa corporal) foram submetidos a um programa de treinamento de 2 sessões/semana por 4 semanas. O protocolo HIIT foi composto por 3 rounds de 2 minutos, com intervalos de 1 minuto, simulando a duração da luta. Cada round foi dividido em 8 blocos de 15 segundos. Cada bloco foi composto por 5 segundos de atividades de alta intensidade, 5 segundos de atividades de baixa intensidade e 5 segundos de pausa. Foram aplicados saltos com contramovimento, salto em agachamento, salto horizontal, teste de aptidão aeróbia (TKDtest) e teste de velocidade de chute (FSOK). Resultados: Os atletas apresentaram aumentos de desempenho no salto com contramovimento (de 41±5,7 para 47,3±7,3cm, p=0,007, g=0,88), salto horizontal (de 1,7±0,4 para 2,3±0,3cm, p=0,01, p=1,56) e no teste FSOK (de 19,8±1,7 a 23,0±2,5 chutes, p=0,003, p=1,38). Afrequência cardíaca em repouso diminuiu (de 120±8,3 para 107±11,4 bpm, p=0,03, p=1,20) e o tempo para exaustão aumentou (de 8,5±1,8 para 13,1±1,4 min, p=0,003, p=2,63), bem como no número de chutes (de 187±55,3 a 368±39,8 chutes, p=0,001, p=3,46). Conclusão: Apesar do pequeno tamanho da amostra, os grandes tamanhos de efeito encontrados permitem sugerir que a adição de um protocolo específico de HIIT para wushu sanda à rotina de treinamento de atletas amadores pode levar a melhorias no desempenho neuromuscular, aeróbio e anaeróbio
Ectopic ossification presenting as osteoid metaplasia in a salivary mucocele in a Shih Tzu dog
<p>Abstract</p> <p>Background</p> <p>Salivary mucocele is an accumulation of saliva in a single or multiloculated cavity lined by connective tissue that is contiguous to a salivary gland-duct complex and is the most common condition affecting the salivary glands in dogs. Occasionally, different types of metaplastic lesions, such as squamous and osseous metaplasia - which are rare lesions in animals - can be observed in association with salivary mucocele.</p> <p>Case presentation</p> <p>A right facial enlargement was suddenly observed in a 4-year-old non-spayed female Shih-Tzu dog. The lesion presented itself as a soft and fluctuant mass located in the right side of the face near to the neck. Histologically, the mass consisted of a cavitary formation without an epithelial lining. Additionally, microscopic examination revealed the presence of osteoid-producing cells which gave rise to areas of bone formation, probably induced by irritation due to the presence sialoliths. Such cells and bone formations were also present in the cavity wall, consequently leading us to classify the condition as a salivary mucocele with osseous metaplasia.</p> <p>Conclusions</p> <p>In the present case, the pathogenesis was probably associated with the presence of sialoliths, which can behave as etiological agents for the metaplastic lesion. The occurrence of osteoid metaplasia is a rare peculiar condition in the canine salivar y gland, and due to the rarity and lack of information about this specific disease, no clinical data can yet be associated with the development of salivary mucocele with osseous metaplasia in dogs.</p
Effect of panretinal photocoagulation on the peripapillary retinal nerve fiber layer in diabetic retinopathy patients
OBJECTIVES: To determine the effect of panretinal photocoagulation (PRP) on the peripapillary retinal nerve fiber layer (RNFL) in nonglaucomatous patients with proliferative diabetic retinopathy (PDR). METHODS: This is a prospective, single center, observational study. Thirty-eight eyes of 26 diabetic patients underwent PRP for proliferative diabetic retinopathy. Peripapillary RNFL thickness was measured using scanning laser polarimetry (SLP) with variable corneal compensation (GDx VCC; by Carl Zeiss Meditec, Dublin, CA) and spectral-domain optical coherence tomography (OCT) (Heidelberg Spectralis, Carlsbad, USA) at baseline and 12 months after PRP was performed. RESULTS: Thirty-eight eyes of 26 patients (15 female) with a mean age of 53.7 years (range 26 to 74 years) were recruited. No significant difference was found among all RNFL thickness parameters tested by GDx VCC software (p=0.952, 0.464 and 0.541 for temporal-superior-nasal-inferior-temporal (TSNIT) average, superior average, inferior average, respectively). The nerve fiber indicator (NFI) had a nonsignificant increase (p=0.354). The OCT results showed that the average RNFL thickness (360o measurement) decreased nonsignificantly from 97.2 mm to 96.0 mm at 1 year post-PRP (p=0.469). There was no significant difference when separately analyzing all the peripapillary sectors (nasal superior, temporal superior, temporal, temporal inferior, nasal inferior and nasal thickness). CONCLUSION: Our results suggest that PRP, as performed in our study, does not cause significant changes in peripapillary RNFL in diabetic PDR patients after one year of follow-up

Oral myiasis in a patient with neurological deficit - Case report / Miíase oral em paciente com déficit neurológico - Relato de caso
The term "myiasis" refers to human and animal parasites caused by fly larvae. The clinical manifestations of myiasis are not specific, they vary according to the area of the body involved and the species of fly. It is strongly associated with poor oral hygiene and is seen in people with predisposing conditions, such as lack of lip sealing due to malocclusion, tooth extraction, decreased body resistance, malnutrition, open-mouth breathing (especially during sleep), alcoholism, senility, neurological disorder, hemiplegia and facial trauma. The present work describes the particularities of diagnosis and treatment of a case of oral myiasis. A 17-year-old male patient with neurological deficit, totally dependent on his daily life activities. Oral examination revealed poor oral hygiene, presence of periodontitis and lesions in the palate and gingival regions, with swelling and presence of large numbers of larvae. Surgery under local anaesthesia was performed. After exposure of the affected region, the larvae were removed. Sixty-two larvae of various sizes were observed. Early and correct diagnosis of oral myiasis can be easily treated by the dentist by mechanical removal of the larvae with or without the use of local chemicals, with a favourable prognosis
