Anomalous origin of the right coronary artery from the opposite sinus (right-ACAOS) with interarterial course (IAC) has been associated with increased risk of sudden cardiac death (SCD). Widespread use of coronary computed tomography angiography (CCTA) has led to increased recognition of this condition, even among healthy individuals. Our study sought to examine the prevalence, anatomical characteristics, and outcomes of right-ACAOS with IAC in patients undergoing CCTA for suspected coronary artery disease (CAD). We conducted a retrospective analysis of consecutive patients referred for CCTA at one tertiary hospital from January 2012 to December 2020. Patients exhibiting right-ACAOS with IAC were analyzed for cardiac symptoms and mid-term occurrence of first MACE (cardiac death, SCD, non-fatal myocardial infarction (MI) or revascularization of the anomalous vessel). CCTAs were reviewed for anatomical high-risk features and concomitant CAD. Among 10,928 patients referred for CCTA, 28 patients with right-ACAOS with IAC were identified. Mean age was 55 ± 17 years, 64% were male and 11 (39.3%) presented stable cardiac symptoms. Most patients had at least one high risk anatomical feature. During follow-up, there were no cardiac deaths or aborted SCD episodes and only 1 patient underwent surgical revascularization of the anomalous vessel. Right-ACAOS with IAC is an uncommon finding (prevalence of 0.26%). In a contemporary population of predominantly asymptomatic patients who survived this condition well into adulthood, most patients were managed conservatively with a low event rate. Additional studies are needed to support medical follow-up as the preferred option in this setting.

ResumoA vasculite mesentérica lúpica (VML) é uma rara causa de dor abdominal aguda. Há poucos relatos de caso demonstrando VML em adultos e, particularmente, em crianças e adolescentes. No entanto, para o nosso conhecimento, a prevalência dessa grave vasculite em uma população pediátrica com lúpus ainda não foi estudada. Portanto, dados de 28 anos consecutivos foram revisados e incluídos 5.508 pacientes em seguimento no Hospital da Faculdade de Medicina da Univesidade de São Paulo (FMUSP). Identificamos 279 (5,1%) casos que preencheram critérios de classificação diagnóstica do American College of Rheumatology para lúpus eritematoso sistêmico (LES) e um (0,4%) desses apresentou VML. Este paciente recebeu diagnóstico de LES aos 11 anos de idade. Aos 13 anos foi hospitalizado com dor abdominal difusa e aguda, náuseas, vômitos biliosos, distensão e rigidez abdominal, com descompressão brusca positiva. O paciente foi prontamente submetido à laparotomia exploradora, identificando isquemia intestinal segmentar, com edema de parede intestinal e aderências. Foi realizada ressecção parcial de intestino delgado, com lise das aderências e pulsoterapia com metilprednisolona. A análise histopatológica identificou arterite de vasos mesentéricos. Após 13 dias, apresentou recorrência de dor abdominal difusa intensa, sendo novamente submetido à laparotomia exploradora, identificando obstrução em intestino delgado por aderências, com gangrena intestinal. Nova ressecção intestinal foi realizada, além de pulsoterapia com metilprednisolona e infusão de imunoglobulina. Portanto, VML é uma rara e grave manifestação abdominal na população com lúpus pediátrico, e pode ser a única manifestação de atividade da doença. Além disso, este estudo reforça a importância do diagnóstico precoce e do tratamento imediato.AbstractLupus mesenteric vasculitis (LMV) is a rare cause of acute abdominal pain. Few cases of LMV have been reported in adults, children and adolescents. However, to our knowledge, the prevalence of that severe vasculitis in a pediatric population with lupus is yet to be studied. This study reviewed data from 28 consecutive years and included 5,508 patients being followed up at the hospital of the Faculdade de Medicina of the Univesidade de São Paulo (FMUSP). We identified 279 (5.1%) patients meeting the American College of Rheumatology classification criteria for the diagnosis of systemic lupus erythematosus (SLE), one of whom (0.4%) had LMV. That male patient was diagnosed with SLE at the age of 11 years. At the age of 13 years, he was hospitalized with diffuse and acute abdominal pain, nausea, bilious vomiting, abdominal distension, rebound tenderness, and abdominal muscle guarding. The patient underwent laparotomy immediately, and segmentary intestinal ischemia with intestinal wall edema and adhesions were identified. Partial small bowel resection with lysis of the adhesions was performed, as were pulses of intravenous methylprednisolone. The histopathologic analysis evidenced mesenteric arteritis. After 13 days, the diffuse and intense abdominal pain recurred, and the patient underwent a new laparotomy, during which adhesive small bowel obstruction with intestinal gangrene was identified. New intestinal resection was performed, and the patient received pulses of intravenous methylprednisolone and infusion of immunoglobulin. Thus, LMV is a rare and severe abdominal manifestation of the pediatric population with lupus, and can be the only manifestation of disease activity. In addition, this study stresses the importance of the early diagnosis and immediate treatment.

To analyze the spatial distribution of leprosy, identify areas of potential case underreporting or high transmission risk, and to assess the ecological association of leprosy distribution with multibacillary cases.This study was carried out in 94 neighborhoods of Recife, Brazil. Data was obtained from the Ministry of Health's Disease Reporting System. An ecological approach with the empirical Bayesian method was applied for local rate flattening, using data from a neighborhood matrix.The mean annual occurrence was 17.3% of new cases in individuals under the age of 15 (28.3% corresponded to multibacillary forms), revealing an intense disease transmission. The spatial distribution of leprosy indicated three areas where there was a concentration of high detection rates and low-income neighborhoods.The Bayesian method allowed to reassess epidemiological indicators based on data from neighboring spatial units. This enabled to identify areas that should be prioritized in municipal control programs, either because of underreporting of cases or the higher number of occurrences related to multibacillary forms in individuals under 15.

The authors present their results on the surgical treatment of pathologic synovial plica in 69 knees of 66 patients. In all patients the synovial plica was the primary pathology and there where no associated knee pathologies. 36 knees were operated between 1979 and 1986 by an open procedure, and 33 had arthroscopic surgery from 1986 to 1991. All patients had previous unsuccessful conservative treatment. The operation was a partial sinovectomy, including all the extension of the synovial plica. The results were obviously superior in the arthroscopic procedure, with 100% of excellent results and quick recovery. All patients in this group had a full range of knee movements by the end of the second week after surgery. In the open surgery group, only 76% of the results were excellent and the full range of movements was obtained only by the fourth or fifth week.
