The Whipple’ Disease (W.D.) is a very rare disease with an incidence of 1 per 1.000.000 inhabitants; it is a systemic infection that may mimic a wide spectrum of clinical disorders, which may have a fatal outcome and affects mainly male 40-50 years old. The infective agent is an actinomycete, Tropheryma Whipplei (T.W.) that was isolated 100 years after first description by Wipple, and identified in macrophages of mucosa of the small intestine by biopsy which is characterized by periodic acid-Schiff-positive, products of the inner membrane of his polysaccharide bacterial cell wall. The multisystemic clinical manifestations evolve rapidly towards an organic decay characterized by weight loss, malabsorption, diarrhea, polyathralgia, opthalmoplegia, neuro-psychiatric disorders and sometimes associated to endocarditis. Early antibiotic treatment with trimethoprim and sulfometathaxazole reduces the fatal evolution of the disease. The authors present a rare experience about a female subject in which the clinical gastrointestinal signs were preceded by neuro-psychiatric disorders, and evolved into obstruction and intestinal perforation which required an emergency surgery with temporary ileostomy, recanalized only after adequate medical treatment with a full dose of antibiotic and resolution of clinical disease for the high risks of fistulae for the edema and lymphadenopathy of mucosa. The diagnosis was histologically examined by intestinal biopsy performed during surgery, which showed PAS-positive histiocytes, while PRC polymerase RNA was negative, which confirms the high sensibility of PAS positive and low specificity of RNA polymerase for T.W.

Las infecciones bucales son producidas por un desequilibrio de la flora indígena del paciente que pasa de comensal a oportunista. Las consultas más frecuentes en niños y adolescentes son las infecciones odontogénicas. El uso racional de antibióticos, es la estrategia más importante para evitar la resistencia microbiana. Las infecciones dentarias deben recibir en primera instancia el tratamiento local correspondiente y a veces complementarse con tratamiento sistémico seleccionando y dosificando adecuadamente el fármaco. El antimicrobiano de primera elección en odontopediatría es la amoxicilina y para pacientes con hipersensibilidad a las penicilinas, se indican claritromicina o clindamicina. Esta revisión de la literatura busca establecer pautas de manejo clínico claras para el tratamiento de urgencia y su posterior resolución definitiva

Background and Objectives: Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive lipid-storage disease caused by mutations in the CYP27A1. The purpose of this study is to determine the clinical characteristics, neuroimaging and mutation detect in a family with CTX systematically. Methods: Collecting history materials and detecting the routine clinical biochemical tests and imaging examination, and for the first time taking the whole body positron emission tomography (PET)-CT examination for probed in the world to research abnormal metabolism activities in CTX. To observe the effect of treatment with chenodeoxycholic acid (CDCA) and stains before and after the intervention, using serum lipid level detection and neuropsychological evaluation. Genetic testing was carried out to screen the nine exons and exon-intron boundaries about 200-300bq of CYP27A1. Results: A 37-year-old woman with typical clinical characteristics of CTX. Magnetic resonance imaging (MRI) of brain showed bilateral lesions in the dentate nucleus of the cerebellum, then, PET images revealed multiple abnormal hypermetabolism areas at distal tendon, and multifocal areas of hypometabolism in bilateral sides of cerebellar hemispheres, the frontal lobe and temporal lobe. Histopathology reveals accumulation of xanthoma cells and dispersed lipid crystal clefts in xanthomas. In genetic analysis, it shown an insertion of cytosine (77-78insC) located in the first exon of CYP27A1 in the proband. Conclusions: We found that a Chinese patient presented a typical clinical feature of CTX along with clear correlation on both structural and functional imaging had a novel mutation in the CYP27A1 gene.

Objective: To analyze, using a literature review, Pulmonary Rehabilitation (RP) Programs in lung transplant. Methods: A literature review in July 2014 in Ebsco Host, Periódicos Capes, BVS and Science Direct data bases using descriptors in English (“lung transplantation”, “lung transplant” AND/OR “rehabilitation”) and Portuguese (“reabilitação” AND/OR “transplante pulmonar”). The eligibility criterions were interventional studies of PR before and/or after lung transplant; participants who were candidates to lung transplant or lung transplant recipients; studies that applied any kind of PR program (hospital-based, homebased or outpatient) and articles published in English, Spanish or Portuguese. Literature reviews, guidelines and case reports were excluded. The search process yielded 46 articles of which two were duplicated. After title and abstract screening 13 articles remained for full text reading. Six studies met the inclusion eligibility and were included in the review. Results: The studies involved patients with Chronic Obstructive Pulmonary Disease, Cystic Fibrosis, Pulmonary Hypertension, Interstitial Lung Disease and Pulmonary Fibrosis. Pulmonary function, exercise capacity, quality of life (QoL) and quadriceps force were evaluated. Most interventions were outpatient programs with three months duration, three times a week and session with at least one hour. Protocols included physical training, educational approach and just one included nutritional, psychiatric and social assistant follow-up. The studies presented significant change in the six-minute walking distance, QoL and quadriceps force after PR programs. Conclusion: This review showed the benefits of the PR in the QoL and exercise capacity contributing to the Health Promotion of the patients.

Acute cholecystitis after colonoscopy is a rare event, with less than 10 cases described in the literature. We report the case of a male patient with silent gallstones who underwent colonoscopy for follow-up of his Crohn’s disease. The colonoscopy revealed erosions in the terminal ileum, from which biopsies were taken. A sessile polyp 4 mm in diameter at the recto-sigmoid junction was also removed. Less than 24 h after the colonoscopy, the patient complained of upper right quadrant pain, nausea and vomiting. Based on the clinical findings, laboratory data and ultrasonography, we diagnosed acute cholecystitis and excluded any complication after the colonoscopy. Laparoscopic cholecystectomy was performed and the patient was discharged.

Here we describe the case of a 19-year-old woman with a poorly differentiated ovarian Sertoli-Leydig cell tumor and an elevated serum alphafetoprotein level. The patient presented with diffuse abdominal pain and bloating. Physical examination, ultrasound, and magnetic resonance imaging revealed a right ovarian tumor that was histopathologically diagnosed as a poorly differentiated Sertoli-Leydig cell tumor with heterologous elements. Her alpha-fetoprotein serum level was undetectable after tumor resection. Sertoli-Leydig cell tumors are rare sex cord-stromal tumors that account for 0.5% of all ovarian neoplasms. Sertoli-Leydig cell tumors tend to be unilateral and occur in women under 30 years of age. Although they are the most common virilizing tumor of the ovary, about 60% are endocrineinactive tumors. Elevated serum levels of alpha-fetoprotein are rarely associated with Sertoli-Leydig cell tumors, with only approximately 30 such cases previously reported in the literature. The differential diagnosis should include common alpha-fetoprotein-producing ovarian entities such as germ cell tumors, as well as other non-germ cell tumors that have been rarely reported to produce this tumor marker.

User studies are a method of measurement that had been used in libraries for many years typically include user studies library circulation. These studies used are those that usually are associated with this term. However, user studies are not as simple as user studies of movement, has a broader meaning depending on what you want to evaluate.

Behçet's disease (BD) is a multi-systemic vascular disorder characterized by oral and genital ulcers, as well as cutaneous, ocular, arthritic, vascular, central nervous system and gastrointestinal involvement. It usually affects young adults, and its pathological origin is unknown. The case of a 47-year-old woman with recurrent ulcers in the oral cavity is presented. She linked the pain with sitting and during the sexual act, with vaginal and oral cavity pain, due to the lesions present at those sites, as well as swelling and pain in the knees, making walk painful. The patient was kept under observation and underwent multidisciplinary treatment with prescription of topical and systemic drugs to improve quality of life. Dentists should be aware of BD and the need of multidisciplinary treatment to increase the patient's quality of life.
