Prevalencia de síntomas músculo-esqueléticos de la mano en estudiantes de odontología / Prevalence of Musculoskeletal Symptoms of the Hand Among Dental Students

Resumen Introducción: Los síntomas músculo-esqueléticos de las extremidades superiores son comunes entre los trabajadores dentales debido a la exposición a factores de riesgo, como movimientos repetitivos, esfuerzos intensos de manos, y malas posturas de muñecas. A medida que los estudiantes de odontología aprenden nuevas habilidades y procedimientos durante la escuela, experimentan un aumento gradual a estos factores de riesgo. El propósito de este estudio fue determinar la prevalencia de los síntomas musculo-esqueléticos (SME) de mano y muñeca entre los estudiantes de odontología de la Universidad de Iowa. Métodos: A 35 estudiantes de primer año y 39 estudiantes de cuarto año (N = 74) se les pidió que llenaran dos cuestionarios. Resultados: La prevalencia de los SME moderados/severos de la mano dominante como entumecimiento, hormigueo y dolor entre los estudiantes de primer año fue de 0, 6 y 20%, respectivamente, comparado con el 18,15 y 36% de los estudiantes de cuarto año. Conclusiones: Los SME de la mano dominante fueron más comunes entre los estudiantes de odontología de cuarto año, en comparación con los de primer año.

Abstract Introduction: Musculoskeletal symptoms of the upper extremities are common among dental workers due to exposure to risk factors including repetition, forceful exertions of the hand, and awkward wrist postures. As dental students learn new skills and procedures during dental school, they experience a gradually increasing exposure to these risk factors. The purpose of this study was to determine the prevalence of hand and wrist musculoskeletal symptoms (MSS) among dental students of the University of Iowa. Methods: Thirty-five first year students and thirty-nine fourth year students (N=74) were asked to complete two questionnaires. Results: The prevalence of moderate/severe MSS of the dominant hand such as numbness, tingling and soreness among first year students was 0, 6 and 20% respectively compared to 18, 15 and 36% of the fourth year students. Conclusions: In this relatively small sample, MSS of the dominant hand were more common among fourth year dental students when compared to first year students.

Acrometástase de Carcinoma de Células Escamosas do Esôfago: Relato de Caso / Acrometastasis of Squamous Cell Carcinoma of the Esophagus: Case Report

Neoplasias metastáticas para as mãos são raras, representando aproximadamente 0,1 % de todo oenvolvimento ósseo metastático e mais excepcionalmente de tumores gastrointestinais, como o carcinoma de esôfago.Objetivo: Relatar um caso atípico de neoplasia de esôfago de células escamosas com acrometástase para mão. Relatode caso: Homem, 48 anos, com quadro clínico de disfagia progressiva. Submetido à endoscopia digestiva alta querevelou lesão ulcerada de bordas elevadas, medindo aproximadamente 12 mm no seu maior diâmetro, com biópsia,que confirmou carcinoma de células escamosas pouco diferenciado e invasor, Grau III. Realizada esofagectomia apósquimioterapia e radioterapia neoadjuvante. Após dois anos do procedimento cirúrgico, paciente evolui com edema,eritema leve e dor local em punho e mão esquerda, restringindo movimentos dos primeiro e terceiro quirodáctilos.Radiografia com extensas lesões osteolíticas, cintilografia óssea com atividade óssea aumentada. Biópsia local confirmoucarcinoma de células escamosas metastático em partes moles, de foco primário do esôfago. Conclusão: Metástaseóssea de extremidade no carcinoma de esôfago é rara. Com aumento da longevidade dos pacientes oncológicos, novaspropedêuticas devem ser discutidas na detecção precoce das metástases óssea...

Musculoskeletal and cutaneous sarcoidosis: exuberant case report.

Sarcoidosis is a multisystem granulomatous disease of unknown cause. The osteoarticular involvement in sarcoidosis is rare and is often associated with cutaneous and long-standing chronic multisystem disease. More common in black women, osseous sarcoidosis is difficult to diagnose, with an incidence of 3 to 13%. The most characteristic radiological clinical picture evidences rounded, well-defined cysts, with no periosteal reaction and without peripheral sclerosis. The small bones of hands and feet are the most frequently involved sites. This report aims to demonstrate a rare case of osteoarticular sarcoidosis with characteristic clinical presentation, and highlight the importance of detecting osteoarticular involvement in this pathology.
