Glomus tumor shows histologically characteristic three components of glomus cells, vascular structures, and spindle-shaped smooth muscle cells. It is classified into solid glomus tumor, glomangioma and glomangiomyoma according to relative proportions of components. Glomangiomyoma, the least frequent type of glomus tumor, has its overall histopathologic pattern identical to common solid glomus tumor or glomangioma. In contrast to the foregoing types, however, it has an important number of spindle-shaped smooth muscle cells, which blend with the glomus cells. A 49-year-old woman presented with 2-year history of painful bluish red nodule beneath nail plate of right 4th finger. We made a diagnosis of glomangiomyoma by virtue of routine histopathologic examinations and immunohistochemical stains such as vimentin, smooth muscle actin and desmin.

OBJECTIVES: This study was performed to investigate the effectiveness of the questionnaire. METHODS: Workers'health examination records, work environment record, and questionnaires of selected industries as samples were analysed using logistic regression analysis and discrimination analysis Results'Cases of bearing impairment (Dl+C) as dependent variables, and age, work duration and level of environmental noise as independent variables were selected for multiple unconditional logistic regression analysis. Odds ratio was 4.04 in hearing difficulty, 2.78 in tlnnitus and 1.08 in age. In the second analysis Noise induced hearing loss is selected as dependent variable. The OR in hearing difficulty was 3.67(95 % C.1. : 1.61 8.61), and was 1.09(95 % C.1. : 1.05-1.14) in age. Conditionnal multlple logistic regression analysis was performed. In hearing impairment as dependent variable, the OR of age was 1.02(95 % C.1. : 1.00-1.04) and other variables were not significant. However, NIHL as dependent, the OR of hearing difficulty was 4.57(95 % C.1. : 1.43-14.67). According to multiple logistic regression adopting each items of questionnaire as dependent variable, the only item of hearing difficulty showed significant difference with hearing ability. The discrimination analysis was performed with the class variable of hearing impairment, and discrimination variables of age, work duration, and environment noise level. The sensitivity of 59 %, and specificity of 88 %, and average error count of 23 % were obtained. When the numbers of items answered in questionnaire were assumed as the parameter of judgement for noise induced hearing loss (NIHL), the highest sensitivity and specificity were 33.5% and 49.0% in cases of more than two items answered. CONCLUSIONS: The development of items that is simple and discriminative mainly consisted of chronic and specific diseases related items is needed. Computerization for newly developed items might be needed to establish effective surveillance system for NIHL in the future.

Squamous cell carcinoma(SCC) is a recognized late complication of chronic discoid lupus erythematosus(CDLE). There are many case reports of SCC in white patients with chronic DLE. However, it is uncommon in blacks and Asians. The etiology of squamous cell carcinoma is multifactorial. The predisposing factors for the development of SCC in these patients include actinic keratosis, Bowen's disease, burn scars, arsenic keratosis, and chronic discoid lupus erythematosus. Of these causes, SCC developing in the lesions of CDLE is very rare. We report a patient who has been evaluated for ten years with a diagnosis of discoid lupus erythematosus and has squamous cell carcinoma.

Dupuytren's contracture is characterized by a proliferative fibroplasia and contracture of the palmar fascia with resultant deformity of hand and finger. It is most common in those of Scandinavian and Celtic origin but it is very rare in the orientals. We experienced 30 hands of 21 patients from January 1985 to December 1995 in Soonchunhyang University Hospital. Among 21 patients, operative treatment was done in 28 hands of 19 patients. Partial fasciectomy was done in 24 hands and complete fasciectomy was done in 4 hands. The longitudinal straight skin incision was done in 14 cases and the transverse or Zig-Zag incision was done in 12 cases. Average follow-up period was 24 months. The results of the operative treatment were classified by Honner's classification. Excellent result was obtained in 16 cases (57%), good in 8 (29%), fair in 3 (11%), poor in 1 (3%). The complications were 5 cases as follows; recurrence 2, skin defect 1, hypoesthesia 2. In conclusion, partial fasciectomy utilizing longitudinal straight incisions overlying diseased area is suggested as one of the good method for the treatment of Dupuytren s contracture.

Intraosseous lipoma is one of the rarest primary benign tumors of bone and it is characterised by a neoplastic overgrowth of univacuolar fat cells. The incidence is less than one per 1,000 bone tumors. Most commonly, long bones are affected, with a tendency for metaphyseal involvement. Because of its rarity and nonspecific clinicopathologic findings, biopsy is needed for accurate diagnosis. Currettage and bone-grafting is the treatment of choice if the lesion is painful or if structural stability is threatened. We report 3 cases of intraosseous lipoma in long tubular bones with review of literatures. Two cases were treated by surgical intervention and the other case by conservative management.

The authors analyzed a series of 49 cases of spinal cord tumor confirmed by operation and biopsy at Presbyterian Medical Center, Jeonju, from Jan. 1977 to Dec. 1981. Histologically vertified spinal cord tumors wereneurofibroma(36.7%: 18/49), meningioma(22.5%; 11/49), ependymoma(18.5%; 9/49), metastasis(10.2%; 5/49),astrocytoma(6.1%; 3/49), epidermoid (2.0%;1.49), glioblastoma multiforme(2.0%;1/49), and diffuse non-Hodgkin'slymphoma(2.0%;1.49). The results were as follows; 1. The most frequently encountered tumor was the intraduralextramedulary tumor(55.1%;27/49). The other tumors, in descending order, were intramedullary tumor(26.5%; 13/49),extradural extradural extramedullary tumor(10.2%;5/49), and intra-&extradural extramedullary tumor(8.2%;4/49).The most frequently encoutered tumor was neurofibroma(36.7%; 18/49). Four of the 18 neurofibroma were intra-&extradural extramedullary tumor, and three(3/4) were dumbbell type of neurofibroma. 2. Only 3 cases occurred under20 years of age. They were glioblastoma multiforme, neurofibroma and epidermoid. 3. No sex predominance of spinalcord tumor was seen, but the majority of the meningiomas occurred in females(81.8%). 4. The most frequent site oftumors was the thoracic region(53.1%;26/49). The order sites were the cervical regions(2.0%;1/49) . 5. Thirteencases (26.5%) showed bony changs on preliminary roentgenograms of the spine. None showed bony changes inextradural extramedullary tumor. 6. As a rule, the myelographic deformities produced by intramedullary tumorshowed fairly long fusiform dilatation of the contrast column without displacement of the spinal cord; theextradural extramedullary tumor showed coarse transverse serrated block of the contrast column; and the intraduralextramedullary tumor showed cup defect of the contrast column.

Purpose: This study was performed to analyze the predictors that might contribute to urinary retention following semiclosed hemorrhoidectomy under spinal anesthesia. Methods: This retrospective study enrolled 2,176 consecutive patients with symptomatic grade III to IV hemorrhoids who underwent semiclosed hemorrhoidectomy between September 2018 and September 2019. Results: Among the 2,176 patients, 1,878 (86.3%) had no postoperative urinary retention, whereas 298 (13.7%) developed urinary retention after hemorrhoidectomy. The percentage of males was significantly higher in the retention group than in the non-retention group (60.4% vs. 48.1%; P=0.001). The risk of urinary retention was 1.52-fold higher in males than in females (95% confidence interval [CI], 1.13–2.04; P=0.005), 1.62-fold higher in old age (95% CI, 1.14–2.28; P=0.006), and 1.37-fold higher with high body mass index (BMI) (95% CI, 1.04–1.81; P=0.025). Patients with ≥4 resected hemorrhoids had a higher odds ratio (OR) of 1.46 (95% CI, 1.12–1.89; P=0.005) than patients with <4 resected hemorrhoids. Among the supplementary medication, patients who used analgesics had a higher OR of 2.06 (95% CI, 1.57–2.68; P=0.001) than those who did not. Conclusion Male sex, age, high BMI, number of resected hemorrhoids, and supplementary analgesics are independent risk factors for urinary retention after semiclosed hemorrhoidectomy.

Purpose: According to recent studies, magnetic resonance imaging (MRI) assessment of complex fistulas provides a significant benefit compared to fistulography, computed tomography, and ultrasonography. The aim of this study was to describe the accuracy of MRI and the importance of identifying puborectalis muscle involvement on MRI in patients with complex fistula. Methods: All patients who were clinically diagnosed with ‘complex’ or showed multiple fistula tracts underwent fistula MRI. Eligible patients were consecutive patients who underwent fistula MRI between September 2018 and September 2019 at our hospital. Results: A total of 83 patients (74 males, 9 females; 116 tracts) were included in this study. The sensitivity and specificity of MRI in diagnosing fistula tracts were 94.8% and 98.2%, respectively. The sensitivity and specificity in identifying internal opening were 93.9% and 97.3%, respectively. Of the 35 patients with puborectalis muscle involvement in the MRI, 31 images of suprasphincteric-type patients on the Park’s classification were classified. The patients of puborectalis involvement were divided into 2 groups according to the surgical procedure that was performed. There were 12 sphincter-saving procedures and 19 sphincter division procedures performed. Recurrence was seen in 2 patients in the sphincter-saving procedure group, while no case was seen in the sphincter division procedure group. Five complications were found in the sphincter division procedure group, of which 2 reported incontinence. Conclusion Fistula MRI is a highly accurate examination for evaluating complex fistulas, and the puborectalis muscle involvement findings are very important for diagnosis and treatment.
