Methods Clinical data of 17 cases with mediastinal enterogenous cysts within 19 years in our hospital were retrospectively analyzed. Results One case was intramural esophageal cyst and 16 cases were enteric cysts, two among which were complicated with abdominal enteric duplications. Most cases presented with symptoms of respiratory distress. Twelve cases were complicated with vertebral anomalies. Ultrasound helpful in confirming the cystic nature of these lesions. posterior mediastinum. of 12 cases and magnetic resonance imaging of 4 cases were Eight cases had technetium-99m pertechnetate scintigraphy of posterior mediastinum.Conclusions Most patients present with symptoms of respiratory distress, complicated with vertebral anomalies. Ultrasonography and magnetic resonance imaging may be helpful in confirming the cystic nature of these lesions. Technetium-99m pertechnetate scintigraphy is the most effective method for differentiation of the disease from other mediastinal cysts.展开更多

These algorithms were adopted from those proposed by the World Health Organization. Methods: A total of 315 consecutive patients with vaginal discharge were enrolled at three STD clinics. Cervical infection was defined as presence of Neisseria gonorrhoeae on culture and/or Chlamydia trachomatis by polymerase chain reaction.Other laboratory tests included wet mount microscopy and pH testing of vaginal fluid. Sensitivity, specificity, and positive predictive value of different algorithms were determined using standard methods. Results: Cervical infection was identified in 37.8% of patients (20.6% gonorrhea, 12.7% chlamydial infection, 4.4%gonorrhea in combination with chlamydial infection). The sensitivity, specificity, and positive predictive value of algorithms A and B for the identification of Neisseria gonorrhoeae and/or Chlamydia trachomatis were respectively 71.4% and90.8%, 65.3% and 46.9%, 55.6% and 50.9%. Conclusions: The vaginal discharge algorithms could be applied for clinical management. Their sensitivities are acceptable. However, there is a need to further improve their specificity and positive predictive value. The two algorithms could be used in clinical settings with different facilities. These algorithms should also be validated in populations with lower disease prevalence.展开更多
