Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

Recently, compensatory impotence has increased with the development of industry, the rise in vehicles, the sexual revolution, the secured legal and insurance services. Compensatory impotence is a medicolegal term for the male erectile dysfunction that requires a doctor's medical certificate and opinion are regarding legal responsibility, reparation or compensation rather than primary medical care of the diagnosis and treatment by the patient or his procurator. We studied 69 cases of compensatory impotence (mean age 38.1, range 24-58) at the Department of Urology, Pusan National University Hospital from January 1987 to December 1995. The marital status were married, separated, single and divorced in 37 (53.6%),14 (20.3%), 13 (18.8%) and 5 (7.3%) cases, respectively. Opinions as to cause of impotence were sought from medical documents of university hospital 34 (49.3%), legal documents required from the court 25 (36.2%) and industrial accident insurance documents 10 (14.5%). Trauma constituted 47 cases (68.1%) while 22 (31.9%) had no history of trauma. With trauma, spinal cord injury was the most common cause of impotence in 18 cases (38.3%), followed by urethral injury in 14 (29.8%), and penoscrotal injury, head trauma, pelvic bone fracture, electrical bum and bladder rupture in 5 (10.6%), 4 (8.5%), 3 (6.4%), 2 (4.3%), and 1 (2.1%), respectively. Organic impotence is predominant cause in trauma group and psychogenic is highest in nontrauma group. Of 34 cases who the impotence therapy was recommended, 14 (41.2%) were accepted. In conclusion, for the evaluation and management of the compensatory impotence with complex issue of legal, financial and social aspects, physician's objective mental attitude and the accurate medical survey with the legal comprehensions are primarily important. Additionally, common criteria for compensation should be established by the cooperative expertise of experts in the fields of medicine, law and insurance.

Purpose: : This study aimed to comprehensively understand the work experience of the person in charge of the adequacy evaluation of small-and medium-sized hospitals and explore its meaning and essence in-depth. Methods: : This was a descriptive qualitative study. The study participants were 10 nurses who understood the purpose of this study and participated voluntarily. Data collection was conducted via in-depth interviews in January 2021. The interviews were conducted 1-2 times per participant and lasted approximately 40-50 minutes per session. Data analysis was performed using a qualitative content analysis. Results: : The work experience of the person in charge of the adequacy evaluation of small-and medium-sized hospitals included four themes: “difficulty in preparing for evaluation,” “negative views on evaluation,” “lack of a support system,” and “positive improvements and changes due to an evaluation.” Conclusion : Based on the above results, an education program and support system should be developed to strengthen the competence of nurses in charge of the adequacy evaluation of small- and medium-sized hospitals.

Purpose: We report a first case of traction retinal detachment accompanied by ocular syphilis in Korea.Case summary: A 20-year-old male visited with poor left-eye vision. His best-corrected visual acuity was 0.3; no inflammation was evident in the anterior chamber, but many inflammatory cells were found in the vitreous cavity. Fundus examination revealed inferior exudative and tractional retinal detachment. Optical coherence tomography revealed an epiretinal membrane; fluorescein angiography showed that the inferior (detached) retina did not fluoresce. Syphilis was serologically detected; ceftriaxone (2 g daily) was intravenously injected for 14 days. The vitreous cavity inflammation improved, but the tractional membrane proliferation triggered tractional retinal detachment. We performed vitrectomy to remove the tractional membrane and prescribed intravitreal antibiotics. The patient was discharged after intravenous injection of penicillin G (20 MU daily) for 14 days. Three months after surgery, the best-corrected left-eye visual acuity had improved to 0.8, and no recurrence of the retinal detachment was noted. Conclusions Patients with ocular syphilis may evidence retinal detachment despite initial prescription of systemic antibiotics. A possible need for surgery should be kept in mind; the prognosis is good if an operation is performed in a timely manner.

Purpose: To evaluate the effect of lacrimal endoscopy on operation time in silicone tube intubation for patients with nasolacrimal duct obstruction. Methods: We conducted retrograde chart review of 168 eyes of 107 patients who were diagnosed with acquired nasolacrimal duct obstruction and underwent silicone tube intubation from January 2019 to February 2023. We analyzed relationship between use of lacrimal endoscopy and operation time, and effect of operation time on success rate of surgery according to use of lacrimal endoscopy. Results: Of 168 eyes, 58 eyes underwent silicone tube intubation with lacrimal endoscopy, and 110 eyes underwent silicone tube intubation without lacrimal endoscopy. Average operation time was 10.98 ± 2.24 minutes in the group with lacrimal endoscopy, and 12.44 ± 4.08 minutes in the group without lacrimal endoscopy. Operation time in the group with lacrimal endoscopy was relatively shorter and statistically significant (p = 0.003). When analyzing correlation between operation time and success rate, success rate decreased by 0.877 times when operation time increased by 1 minute in the entire group, and there was statistical significance (p = 0.022). There was no statistical significance in the correlation between operation time and success rate in the group with lacrimal endoscopy. And in the group without lacrimal endoscopy, success rate decreased by 0.865 times when operation time increased by 1 minute, and there was statistical significance (p = 0.019). Conclusions In silicone tube intubation for nasolacrimal duct obstruction, Lacrimal endoscopy is considered an effective treatment that can shorten operation time and prevent complications while accurately diagnosing cause and extent of obstruction by investigating the inside of the nasolacrimal duct.

PURPOSE: To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. RESULTS: On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gasshadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer infour cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focallow density lesion suggestive of focal abscess was not visualized. CONCLUSION: Plain radiography is useful forearly diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

Schwannomas are benign tumors derived from the Schwann cells of the nerve sheath. These are rare tumors that can be found in any part of the body although fewer than 4% of these tumors involve the nasal cavity and paranasal sinuses. Here, we present three cases of sinonasal schwannoma. The tumor masses were removed by endoscopic excision under general anesthesia. Pathological examination of the excised specimens confirmed schwannoma and the tumor cells were immunoreactive for S-100 protein. The patients are doing well with no evidence of recurrence.
