A tuberculose é uma doença de alta incidência e prevalência no Brasil. Sinais sugestivos de atividade ou seqüela da tuberculose podem ser obtidos através dos métodos de imagem. Na radiografia de tórax, a tuberculose pulmonar ativa pode manifestar-se sob a forma de consolidações, cavitações, padrões intersticiais (reticulares/retículo-nodulares), linfonodomegalias hilares ou mediastinais e derrame pleural. Imagens compatíveis com doença ativa, como nódulos centrolobulares de distribuição segmentar, cavidades de paredes espessas, espessamento de parede brônquica ou bronquiolar, bronquiectasias e linfonodomegalias, podem ser observadas pela tomografia computadorizada do tórax; cavidades de paredes finas, bronquiectasias de tração e estrias são imagens sugestivas de seqüela da doença, assim como o enfisema e o aspecto em mosaico do parênquima pulmonar. A cintilografia com o citrato de gálio-67 é um método complementar útil na detecção de processos infecciosos, incluindo a tuberculose, especialmente em pacientes imunossuprimidos. Estudos de inalação e perfusão pulmonar são utilizados na avaliação pré-operatória de pacientes com seqüelas de tuberculose ou tuberculose multirresistente. A tomografia por emissão de pósitrons utilizando a deoxiglicose marcada com o flúor-18 permite a detecção do processo inflamatório que ocorre na fase ativa da tuberculose e que pode persistir, em menor intensidade, após o término do tratamento. Métodos de imagem constituem importantes recursos para o diagnóstico e acompanhamento da tuberculose pulmonar.
Since the outbreak of the novel coronavirus disease 2019 (COVID-19), all health services worldwide underwent profound changes, leading to the suspension of many elective surgeries. This study aimed to evaluate the safety of elective colorectal surgery during the pandemic. METHODS: This was a retrospective, cross-sectional, single-center study. Patients who underwent elective colorectal surgery during the COVID-19 pandemic between March 10 and September 9, 2020, were included. Patient data on sex, age, diagnosis, types of procedures, hospital stay, mortality, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preoperative screening tests were recorded. RESULTS: A total of 103 colorectal surgical procedures were planned, and 99 were performed. Four surgeries were postponed due to positive preoperative screening for SARS-CoV-2. Surgical procedures were performed for colorectal cancer (n=90) and inflammatory bowel disease (n=9). Laparoscopy was the approach of choice for 43 patients (43.4%), 53 (53.5%) procedures were open, and 3 (3%) procedures were robotic. Five patients developed COVID-19 in the postoperative period, and three of them died in the intensive care unit (n=3/5, 60% mortality). Two other patients died due to surgical complications unrelated to COVID-19 (n=2/94, 2.1% mortality) (po0.01). Hospital stay was longer in patients with SARS-CoV-2 infection than in those without (38.4 versus 10.3 days, respectively, po0.01). Of the 99 patients who received surgical care during the pandemic, 94 were safely discharged (95%). CONCLUSION: Our study demonstrated that elective colorectal surgical procedures may be safely performed during the pandemic; however, preoperative testing should be performed to reduce in-hospital infection rates, since the mortality rate due to SARS-CoV-2 in this setting is particularly high.
Late recanalization improved LV ejection fraction and myocardial contractility in late follow-up, but did not change the ventricular volumes. Improvement in the left ventricle global and regional contractility may benefit the long-term outcome in post-MI patients with sustained patency of the infarct-related artery.
BACKGROUND: The post-operative complications rate is greater in patients with Crohn’s disease than in other abdominal surgeries due to other benign conditions. Prevention and management of such complications are important factors in the care of these patients. OBJECTIVE: The objectives of this research are to analyze the rate of postoperative complications and the major risk factors in patients with Crohn’s disease. METHODS: A descriptive and retrospective study based on analysis of medical records of patients with Crohn’s disease undergoing ileal and/or colonic resection, which analyzed the main surgical complications and their major risk factors. RESULTS: Forty-four surgical procedures and thirty-seven patients were analyzed. Most were female (56.7%). Postoperative complications were observed in 18 (40.9%) surgeries. The disease duration (P=0.04), the penetrating behavior (P=0.013), the time between diagnosis and the first surgery (P=0.04), malnutrition with low body mass index (BMI), duration of surgery (P=0.016), and the size of the removed specimen (P=0.014) were associated with higher rates of complications. The use of drugs blocking tumor necrosis factor up to eight weeks before surgery was not significantly associated with higher complications rates or increased need for reoperation. CONCLUSION: The complication rate observed in this study is similar to published data. The duration of the disease, the penetrating behavior, the size of the removed specimen, the duration of the surgery, and BMI are important risk factors for perioperative complications in Crohn’s disease.
Patient: Female, 81-year-old
Final Diagnosis: Anorectal malignant melanoma
Symptoms: Hematochezia • obstipation • pain • tenesmuss
Medication: —
Clinical Procedure: —
Specialty: Gastroenterology and Hepatology • Oncology
Objective:
Rare disease
Background:
Anorectal mucosal melanoma (AMM) is a rare and aggressive neoplasm, with a 5-year survival rate of 10%. Due to its rarity and nonspecific symptoms, the diagnosis is often made late. Surgical resection remains the criterion standard for treatment of anorectal melanoma.
Case Report:
We present the case of an 81-year-old woman presenting with hematochezia, anal secretion, tenesmus, difficulty in defecation, and perianal pain. On physical examination, there was a prolapse of a 5-cm melanocytic nodule in the anal canal, hard on palpation. Biopsy confirmed anorectal melanoma. Staging revealed anal and metastatic disease, with adrenal, lymphatic, and hepatic involvement. As the patient continued to have bleeding, severe pain, and difficulty in defecation, she was submitted to a wide local excision. At 5-month follow-up, the anal lesion had relapsed, and the patient died 10 months after the procedure.
Conclusions:
AMM is a rare and extremely aggressive tumor. Symptoms are nonspecific but early diagnosis should be pursued to allow curative treatment. Surgical resection with free margins is the goal of surgical treatment. New therapies are being studied, including immunotherapy, which can improve the dismal prognosis of this rare disease.
