Mesenteric adenitis consists of an important differential diagnosis of potentially serious diseases such as acute appendicitis, since they manifest themselves with a similar clinical picture. Case report: A 17-year-old male patient presented with periumbilical abdominal pain for 2 days, of abrupt onset and moderate intensity, who gave away with a common analgesic, which progressed to the right iliac fossa (RIF) and increased of intensity. He also reported liquid diarrhea, with several episodes a day, without mucus and/or blood, 38˚C fever, anorexia and vomiting. He was hospitalized for investigating a possible diagnostic of Acute Appendicitis. In the exams, it was considered mesenteric adenitis, and antibiotic therapy was prescribed. The patient had complete improvement at the end of treatment. Conclusions: Given its importance as a differential diagnosis of numerous pathologies, as well as controversial before the therapeutic and diagnostic conduct, it is essential to report these cases in order to elucidate the specificities of this disease.

Introduction: The involvement of undergraduate student at the beginning of their training in activities based on Primary Health Care (PHC), provides preventive and health promoting actions, and ensures the evaluation of the vulnerability of communities and people. Objectives: To analyze the opinion of students and teachers of two medicine higher education institutions on the relevance of Primary Health Care in this course. METHODS: Students and teachers should be effectively enrolled in order for the study to be conducted, being chosen in a random manner and without interferences on the part of the researchers so that the work was as reliable as possible. A cross-sectional study was conducted with interviews structured in questionnaires about what they thought about PHC. To some students and teachers of the medical course of Valença and Grande Rio University (UNIGRANRIO). Before receiving the questionnaire, all interviewed signed a Free and Informed Consent Term, which included the objectives and methodology of the work. Results: 310 students and 51 teachers participated in the study, where 91.43% of the students and 100% of the teachers affirmed that primary care plays a fundamental role in medical education. 94.86% of students and 97.91% of teachers, claimed that the discipline allows a greater contact between undergraduates and community. When questioned about the encouragement that teachers give to students to pursue a career in PHC, 57.87% of the students and 70

The cotton plant is a plant belonging to the family Malvaceae and its leaves are often used in folk medicine. The present study aimed to evaluate the mutagenic or antimutagenic activity of the ethanolic extract of Gossypium barbadense L. (EEG) and to analyze its capacity to prevent or repair mutagenic lesions caused by cyclophosphamide (CP). For the Micronucleus test, Swiss mice were divided into 5 groups: negative control; Positive control: treated with 50 mg/kg cyclophosphamide (CP), group receiving EEG 500 mg/kg for 7 days; Group receiving EEG 500 mg/kg for 7 days associated with CP24h before euthanasia; Group who received CP and EEG 500 mg/kg for 7 days. After the treatment period, the animals were euthanized, the bone marrow removed and the blood smear prepared. From this analysis, it was observed that the EEG caused a significant increase in the number of micronucleated erythrocytes, indicating mutagenic activity of the extract. In addition, it was verified that the extract did not present the capacity to prevent, but it presented the capacity of repair of the chromosomal damages caused by CP.

Darier disease (DD), also known as follicular keratosis, is a rare autosomal dominant hereditary acantholytic dermatosis caused by a mutation in the ATP2A2 gene. Skin lesions are characterized by persistent confluent papules, preferentially located on the seborrheic areas of the face, chest and back. The hands, feet and nails are also commonly affected. DD has a chronic course with frequent relapses. Their treatment is often difficult and unsatisfactory. We present the case of a 54-year-old male with a history of keratotic papules with a brownish-black color, with a foul-smelling, pruritic and ardent appearance on the back and trunk, since the age of 19, which worsen in the summer. His 27-year-old daughter has a similar picture with her skin lesions started at age of 17 in the region below the breast, back, trunk, feet and hands. After the skin biopsy, the diagnosis was confirmed and acitretin 30 mg/day was instituted. The importance of this case report is to alert health professionals that the diagnosis of DD should be considered in family members of patients, especially those in the first degree, and also in patients with follicular keratolytic dermatoses, being an important differential diagnosis of this group of patients diseases.
