Prognostic Factors for Tracheal Restenosis after Stent Removal in Patients with Post-Intubation and Post-Tracheostomy Tracheal Stenosis

Purpose@#Long-term tracheal stent placement can increase the risk of stent-related complications; hence, removal of the stent after stabilization is attempted. However, little evidence has been established regarding the risk factors for tracheal restenosis. We aimed to identify the risk factors for tracheal restenosis in patients with post-intubation tracheal stenosis (PITS) and post-tracheostomy tracheal stenosis (PTTS). @*Materials and Methods@#We retrospectively analyzed patients with PITS and PTTS between January 2004 and December 2019. Patients were classified into a success or failure group according to treatment outcomes. Patients with successful stent removal were defined as patients who did not require additional intervention after stent removal during the follow-up period. Multiple logistic regression analysis was performed to identify the factors associated with tracheal restenosis. @*Results@#Among 269 stented patients, 130 patients who had removed the stent were enrolled in this study. During the follow-up period, 73 (56.2%) patients had a stable clinical course; however, 57 (43.8%) patients had restenosis. The proportion of trauma-induced intubation was higher in the success group than in the failure group (p=0.026), and the median stent length was shorter in the success group (45 mm) than in the failure group (50 mm, p=0.001). On multivariate analysis, trauma-induced intubation [adjusted odds ratio (aOR), 0.329; 95% confidence interval (CI), 0.117–0.927; p=0.036], and stent length <50 mm (aOR, 0.274; 95% CI, 0.130–0.578; p=0.001) were associated with a decreased risk of restenosis. @*Conclusion@#Trauma-induced intubation and stent length were associated with successful stent removal.

Multidrug-Resistant Tuberculous Mediastinal Lymphadenitis, with an Esophagomediastinal Fistula, Mimicking an Esophageal Submucosal Tumor

Mediastinal tuberculous lymphadenitis rarely mimics esophageal submucosal tumor, particularly in the case of multidrug-resistant tuberculosis (MDR-TB). Herein, we report the case of a 61-year-old woman who visited a local hospital complaining of odynophagia. An initial esophagogastroduodenoscopy revealed an esophageal submucosal tumor, and subsequent chest computed tomography showed subcarinal lymphadenopathy with an esophagomediastinal fistula. The patient was then referred to Samsung Medical Center, and a second esophagogastroduodenoscopy showed deep central ulceration, as well as a suspicious fistula in the esophageal submucosal tumor-like lesion. A biopsy examination of the ulcerative lesion confirmed focal inflammation only. Next, an endobronchial, ultrasound-guided lymph node biopsy was performed, and TB was confirmed. The patient initially began a course of isoniazid, rifampicin, ethambutol, and pyrazinamide. However, after a drug sensitivity test, she was diagnosed with MDR-TB, and second-line anti-TB medications were prescribed. She recovered well subsequently.

A Rapidly Expanding Ascending Aortic Aneurysm in a Patient with Relapsing Polychondritis / 대한내과학회지

Here we describe a case of rapidly expanding ascending aortic aneurysm in a patient with relapsing polychondritis. To prevent aneurysm rupture, the patient underwent emergent surgical repair. Silent inflammation can progress in the aorta wall, even in asymptomatic patients with mild disease activity under immunosuppressive treatment, leading to the rapid growth of aortic aneurysms. Close monitoring with routine imaging is needed once a patient with relapsing polychondritis is diagnosed with an aortic aneurysm.

A Pilot Study of the Impacts of Menopause on the Anogenital Distance

OBJECTIVES: It has been known that there is a difference in anogenital distance (AGD) in the animals and newborn depending on the exposure of androgenic hormones. The anatomical changes occur in the female genitalia in women after menopause. This was pilot study to find out whether the menopause affects AGD. METHODS: We evaluated a total of 50 women targeted for premenopausal and postmenopausal group in each 25 people. AGD was defined as a length between the posterior commissure of labia and anal center. AGD was measured in lithotomy position using sterile paper ruler. In order to control bias of the height and weight, which could influence the AGD, anogenital index (AGI) is defined as the weight divided by the AGD value. We used a Mann-Whitney U test to analyze the relationship between AGD and menopause for statistical analysis. RESULTS: AGD was significantly longer in premenopausal women compared to postmenopausal women (34.8 +/- 6.4 vs. 30.3 +/- 6.6, P = 0.019). AGI was significantly higher in premenopausal women than postmenopausal women (1.7 +/- 0.4 vs. 1.3 +/- 0.3, P < or = 0.000). CONCLUSION: The changes of AGD and AGI in postmenopausal women demonstrated to have potential to be used as on scale predicting the physical changes that may occur after menopause. This study could be used as the cornerstone of a large-scale studies in the future.

Gynecologic complication of chronic graft-versus-host disease: Vaginal obstruction

Allogenic peripheral blood stem cell transplantation (Allo-PBSCT) is being used to treat hematological malignancies with increasing frequency. Graft-versus-host disease (GvHD) is a complex complication of PBSCT. A 43-year-old woman came to the gynecology clinic for amenorrhea. She had been diagnosed with acute myeloid leukemia 2 years earlier and treated with induction and consolidation chemotherapy. After developing complete remission, she underwent Allo-PBSCT. When she started chemotherapy, her menstrual cycle completely disappeared. Fourteen months after menopausal hormone replacement therapy, it was discovered that her upper vaginal canal was completely obstructed. The lower vagina had an atrophic appearance. We report a rare case of partial vaginal obstruction as a complication of chronic GvHD and review the literature. We expect that this case report provides an opportunity to remind clinician of the gynecologic complications of GvHD.

Qualitative Research on Experience of Primary Physicians Operating Their Primary Health Care Centers / 가정의학회지

BACKGROUND: The purpose of the study was to understand how family physicians managed their primary health care centers and to identify the factors for successful management of their privative clinics. METHODS: The data was collected through individual interviews from five family physicians who operated their private clinics. All interviews were tape-recorded and transcribed into verbatim data. The data was analyzed using qualitative content analysis. RESULTS: Three major categories were identified: 1) types of physician based on major value as a doctor; 2) difficulties in operation and management; 3) desirable operating strategies for success. The first category described what kinds of value the physicians pursued as they operated their private clinics. Two different types were identified. One was intrinsic value oriented and the other was extrinsic value oriented. The second category illustrated many difficulties that family physicians faced in operating and managing their private clinics. Lack of private time, social isolation, and gap between mission and reality of practice were identified as major difficulties. Desirable strategies for the successful management were four subcategories: location; self-oriented developmental plan; specialization of the services; and activating network with larger hospitals. CONCLUSION: The results of the study would be helpful in setting up and operating private clinics through understanding the difficulties and strategies of primary physicians and recognizing mission and major value of them.
