RESUMEN
About 2% of all lung malignancies are pulmonary carcinoid tumors, a family of neuroendocrine tumors. Rarely does a typical tracheal carcinoid of the trachea manifest as an endoluminal polypoidal tumor. Case presentation: The author describe a 61-year-old nonsmoker who complained of growing nonexertional shortness of breath 5 years ago. She also had a wheezy chest and a dry cough. The results of the chest radiography and electrocardiogram revealed no noteworthy abnormalities. The results of the pulmonary function test supported the diagnosis of bronchial asthma. A patient's treatment has not advanced. After performing a bronchoscopy, a biopsy was taken and sent for pathological analysis. The endobronchial lining was found to have a subepithelial tumor infiltrate made up of nests of homogeneous bland cells with central nuclei and mild granular cytoplasm, according to histopathologic analysis. Considering all of these findings, the patient was diagnosed with a primary tracheal carcinoid tumor, which was misdiagnosed and treated as bronchial asthma. Discussion and conclusion: People with stridor or trepopnea symptoms should undergo a computed tomography scan since central airway tumors can mimic the symptoms of bronchial asthma while a chest radiograph may be normal. Tracheal carcinoid that has not progressed to the mediastinum can be successfully removed with flexible bronchoscopy and electrocautery, but the excision site needs to be continuously watched for recurrence.
RESUMEN
BACKGROUND AND OBJECTIVES: The study was sought to detect the effect of Listeria monocytogenes on pregnant Iraqi women at Al-Diwaniya hospitals and determination of virulence genes and antimicrobial susceptibility of isolates. MATERIALS AND METHODS: 360 specimens including blood, urine, vaginal and endocervical were collected from 90 patients with spontaneous abortions. Blood samples were displayed to immunological study and remaining specimens were subjected to bacteriological diagnosis. PCR was used to determine the virulence factors and antimicrobial resistance genes. RESULTS: Fifteen positive samples (16.6%) of patients and thirteen isolates (14.5%) from patients were recognized based on ELISA and PCR assay respectively. The general isolation of L. monocytogenes strains in cases of abortive women was 13/270 (4.8%). L. monocytogenes strains were highly virulent because of presence of virulence factors associated genes, namely actA, hlyA, plcA and prfA in all strains. Multiple drug resistance (MAR) index values of 15.4% of isolates were >0.2. CONCLUSION: It is necessary for conducting susceptibility testing and to select the suitable antibiotics and avoid the effects of these bacteria in pregnant women.
