ObjectiveTo investigate the association between diabetes and latent tuberculosis infections (LTBI) in high TB incidence areas.DesignCommunity-based comparison study.SettingOutpatient diabetes clinics at 4 hospitals and 13 health centres in urban and rural townships. A community-based screening programme was used to recruit non-diabetic participants.ParticipantsA total of 2948 patients with diabetes aged older than 40 years were recruited, and 453 non-diabetic participants from the community were enrolled.Primary and secondary outcome measuresThe interferon-gamma release assay (IGRA) and the tuberculin skin test were used to detect LTBI. The IGRA result was used as a surrogate of LTBI in logistic regression analysis.ResultsDiabetes was significantly associated with LTBI (adjusted OR (aOR)=1.59; 95% CI 1.11 to 2.28) and age correlated positively with LTBI. Many subjects with diabetes also had additional risk factors (current smokers (aOR=1.28; 95% CI 0.95 to 1.71), comorbid chronic kidney disease (aOR=1.26; 95% CI 1.03 to 1.55) and history of TB (aOR=2.08; 95% CI 1.19 to 3.63)). The presence of BCG scar was protective (aOR=0.66; 95% CI 0.51 to 0.85). Duration of diabetes and poor glycaemic control were unrelated to the risk of LTBI.ConclusionThere was a moderately increased risk of LTBI in patients with diabetes from this high TB incidence area. This finding suggests LTBI screening for the diabetics be combined with other risk factors and comorbidities of TB to better identify high-risk groups and improve the efficacy of targeted screening for LTBI.

Computed tomography (CT)-guided transthoracic lung biopsy is a common procedure for the diagnosis of pulmonary lesion. Pneumothorax, pulmonary hemorrhage and hemoptysis are the most common complications of the procedure. Air embolism is a rare serious complication. We reported a case with air embolism related acute ischemic stroke and non-ST elevation myocardial infarction (NSTEMI) simultaneously after percutaneous transthoracic lung biopsy.

Patient: Female, 60Final Diagnosis: Acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess • esophageal perforationSymptoms: Fever • painful swallowing • chest painMedication: —Clinical Procedure: Drainage • debridement • esophageal reconstructionSpecialty: SurgeryObjective:Rare diseaseBackground:Acute phlegmonous esophagogastritis is a life-threatening disease that may be combined with serious complications. We present the classical radiological and endoscopic features and treatment strategy of a middle-aged female patient suffering from acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess, esophageal perforation, mediastinitis, and empyema.Case Report:A 60-year-old Taiwanese female presented at our hospital due to fever, fatigue, painful swallowing, and vague chest pain for 5 days. She had a past history of uncontrolled type 2 diabetes mellitus. On physical examination, general weakness, chest pain, odynophagia, and a fever up to 38.9°C were found. Positive laboratory findings included leukocytosis (leukocyte count of 14.58×103/μL, neutrophils 76.8%) and serum glucose 348 mg/dL (HbA1c 11.3%). A diagnosis of acute phlegmonous esophagogastritis with hypopharyngeal abscess was made based on typical computed tomography image features and clinical signs of infection. The patient received empirical antibiotic therapy initially; however, esophageal perforation with mediastinitis and empyema developed after admission. Emergency surgery with drainage and debridement was performed and antibiotics were administered. She was discharged in a stable condition on the 56th day of hospitalization. Six months later, a delayed esophageal reconstruction was performed. The patient has performed well for 9 months to date since the initial diagnosis.Conclusions:Acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess and esophageal perforation is extremely rare, and requires immediate medical attention. This report serves to remind physicians of this rare entity and the potential complications that may manifest with acute phlegmonous esophagogastritis.
