Abstract INTRODUCTION: Musculoskeletal (MSK) disorders are a major cause of disability worldwide. Different modifiable risk factors are associated to these disorders. The objective of this study was to analyze the burden of low back pain (LBP), rheumatoid arthritis (RA), osteoarthritis (OA), and gout, attributable to risk factors, in 2017. METHODS: The burden of LBP, RA, OA, and gout, and attributable risk factors were analyzed using data extracted from the Global Burden of Disease (GBD) Brasil-2017 study. Descriptive analysis was conducted to compare disability-adjusted life years (DALY) rates between sexes and age groups (15-49 and 50-69 years), in 2017. RESULTS: The highest rates of DALY due to LBP were attributed to occupational ergonomic factors in the 15-49-year group, regardless of sex and males aged 50-69 years, whereas smoking was the major contributor in the 50-69-year female group. RA-related DALY rates were attributed to smoking and were higher among women aged 50-69 years. High body mass index (BMI) was the most relevant risk factor for the burden of OA, with higher rates detected in the 50-69-year group, and it was the most significant risk factor for DALY rate attributed to gout, regardless of sex or age group. CONCLUSIONS: Occupational surveillance measures are indicated to prevent LBP. Actions to decrease smoking and overweight, and the surveillance of weight gain are warranted to decrease the burden of LBP, RA and OA, and gout, respectively. These actions will be more effective if age and sex differentials are considered in planning.

A intussuscepção do intestino delgado em adultos é rara e geralmente está associada à presença de neoplasias. Dentre estas, o GIST, a neoplasia mesenquimal em 30% dos casos é considerada de alto grau de malignidade , são ainda menos comuns. A intussuscepção relacionada ao GIST tem sintomatologia inespecífica e pode manifestar-se com obstrução, massa palpável no abdômen, hemorragia ou perfuração intestinal. Relata-se caso de intussuscepção intestinal em paciente adulto por GIST, com ênfase em seu diagnóstico e tratamento.

Small intestinal intussusception in adults is rare and generally associated with neoplasms. Within them GIST, a mesenchymal neoplasm in which 30% of patients have high grade malignancy, are even less common. Intussusception and GIST may have unspecific symptoms and it almost always presents with obstruction, palpable abdominal mass, hemorrhage and bowel perforation. A case of intestinal intussusception in adult due to GIST is reported, emphasizing diagnose and treatment.

O câncer colorretal localmente invasivo, que acomete por contiguidade estruturas adjacentes e sem metástases à distância, ocorre de 5 a 18% dos casos. São adequadamente tratados com ressecção do tumor e órgãos comprometidos em monobloco e margens livres. É relatado o caso de paciente de 27 anos, masculino, portador de adenocarcinoma de retossigmóide com extensa invasão para bexiga e ceco. Tratado com colectomia total, cistectomia radical em monobloco e ileostomia. O trânsito urinário foi reconstituído com reservatório ileal e anastomose com a uretra prostática. O estudo anátomo-patológico da peça cirúrgica revelou adenocarcinoma moderadamente diferenciado, invasão perineural e invasão da parede da bexiga (T4, N0). Realizou no pós-operatório quimioterapia adjuvante, 6 ciclos, com 5-Fluorouracil e ácido folínico. Após 36 meses de seguimento, o paciente encontra-se livre de doença neoplásica, função urinária preservada, porém com ejaculação retrógrada.

The locally advanced colorectal cancer compromises adjacent structures and do not disseminate distant metastasis, occur in 5 to 18% of patients. It is properly treated with tumour resection as well as other compromised organs in an "en bloc" resection with free margins. We report a 27 year old, male patient with colorectal adenocarcinoma invading the urinary bladder and cecum. He was treated with total colectomy associated with radical cistectomy and ileostomy. The urinary transit was established building an ileal reservatory anastomosed to the urethra. The tumour histopathologic study showed adenocarcinoma moderate differentiated, invading urinary bladder (T4N0). Postoperative treatment was 5-fluorouracil and folinic acid chemotherapy. After 36 months of outcome, patient is improving and preserves urinary function but has ejaculatory dysfunction.

As hérnias perineais primárias resultam de um defeito no assoalho pélvico que permite a passagem de conteúdo abdominal para a região pelve-perineal. É uma enfermidade rara, tendo sido descritos menos de cem casos até hoje. Apresentamos o caso de uma paciente jovem com queixa recente de tumoração glútea dolorosa que, mesmo após o exame físico e tomográfico, não teve sua etiologia esclarecida. Foi então submetida à ressecção cirúrgica da lesão via perineal, quando se confirmou tratar-se de saco herniário isquiorretal esquerdo transpondo defeito no músculo elevador do ânus. Evoluiu sem intercorrências no pósoperatório e sem indícios de recidiva.

Primary perineal hernias result from a defect in the pelvic floor. It is a rare disease, having been described less than one hundred cases until today. We present a case of a young patient with recent complaint of painful gluteal tumor that even after the physical examination and CT did not clarified its etiology. She was submitted to a perineal resection of the lesion that confirmed being a hernia. She is going well without recurrence.
