OBJECTIVES: Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. METHODS: The subjects of this study was 200 diagnosed persons as pneumoconiosis, of whom 100 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and com pared. RESULTS: The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zinc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. CONCLUSIONS: As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.

Synovial chondromatosis is a rare lesion in the wrist, but some cases in the distal radioulnar joint have been reported and previous case reports emphasize joint calcifications, shown on preoperative plain radiographs. We report an extremely uncommon case of synovial chondromatosis in the pisotriquetral joint, in which radiographs and magnetic resonance imaging did not demonstrate apparent calcified bodies. In our case, for the accurate diagnosis and treatment, surgical exploration of the joint and synovectomy with removal of loose bodies was performed.

The ameloblastic carcinoma is an extremely rare, aggressive odontogenic neoplasm of the jaws. It is described as an ameloblastoma in which there is histologic evidence of malignancy in the primary or recurrent tumors, regardless of whether it has metastasized. We report an aggressive case of ameloblastic carcinoma of the mandible. A 68-year-old man with the complaint of the left facial swelling and intermittent pain was referred to our hospital. Serial images of panoramic radiograph, computed tomograph, and magnetic resonance imaging showed an ill-defined destructive radiolucent lesion of the left mandible. The lesion had typically aggressive behavior with extensive local destruction of bone and extended to the adjacent soft tissues. Bone scan revealed increased uptakes in the left mandibular body and ramus regions. Histological features were generally resembled with those of an ameloblastoma but with cytologic features of epithelial malignancy.

OBJECTIVE: To evaluate the clinical applicability and safety of absorbable synthetic suture materials (Safil(R)/Safil(R)Quick/Monosyn(R)) in obstetrical surgeries. METHODS: This clinical trial includes 100 patients who delivered vaginally and 198 patients who were undergone cesarean section from April 2004 to September 2004. In cases of vaginal delivery, patients were divided with the same number into the study group in which Safil(R) Quick was used and the control group in which chromic catgut was used for episiotomy and perineal laceration repair. In case of cesarean delivery, patients were divided into two groups. The first group which included 100 patients was subdivided with the same number into the study group in which Monosyn(R) was used and the control group in which chromic catgut was used for uterine repair. The second group which included 98 patients was subdivided with the same number into the study group in which Safil(R) was used and the control group in which Vicryl was used for rectus fascia repair. Wound healing status and complications are assessed during postoperative stage, at hospital discharge, and at postpartum out-patients follow-up. RESULTS: Compared with chromic catgut groups, Safil(R) Quick group showed no difference in hospital stay from vaginal delivery, wound healing status and surgical complications and Monosyn(R) group showed no difference in operating time, decrease in hemoglobin at postoperative day 3 and surgical complications. Safil(R) group showed no difference in operating time, postoperative pain and surgical complications compared with Vicryl group. CONCLUSION: Safil(R)/Safil(R) Quick/Monosyn(R) were equivalent with regard to most aspects of their clinical suitability and may be useful alternative suture materials in obstetrical surgeries.

OBJECTIVE: To investigate the subcellular localization of nuclear factor kappa B (NF-kappa B) in term human fetal membranes and myometrium during labor. METHODS: Fetal membranes and myometrial tissue were collected from term pregnant women undergoing cesarean delivery after labor (n=4) and before labor (n=4). An immunostaining was done with NF-kappa B p65 antibody. The intensity and distribution of nuclear immunostaining of NF-kappa B p65 subunit were evaluated visually using a semiquantitative analysis. RESULTS: NF-kappa B p65 was present in all tissues studied, and it was localized principally in the cytoplasm of cells of amnion and chorion. But, NF-kappa B p65 was localized more abundant in the nucleus than in the cytoplasm in myometrial cells. In amnion, chorion and myometrium, the staining scores of nuclear NF-kappa B did not show any difference between the after-labor group and before-labor group. CONCLUSION: In human term gestational tissues, subcellular localization of NF-kappa B showed cytoplasmic predominance in amnion and chorion, and nuclear predominance in myometrium. But these subcellular localizations did not change during labor.

Vertebral ankylosing hyperostosis is a systemic rheumatological abnormality of unknown etiology whose hallmark is luxurious flowing ossification of the anterior longitudinal ligament. It has been regarded as asymptomatic ankylosis requiring no medical or surgical treatment. However, dyspnea, dysphagia, spinal cord compression, and peripheral nerve entrapment have all been documented in association with this disorder. On the other hand, reports on spinal stenosis at lumbar level are extremely rare. We present a case of spinal stenosis assosiated with vertebral ankylosing hyperostosis.

PURPOSE: Circular stapled hemorrhoidopexy (CSH) is widely used to treat patients with grades III–IV hemorrhoids because of less pain and short hospital stay. However, this procedure is associated with some complications, such as urge to defecate, anal stenosis, staple line dehiscence, abscess and sepsis. To avoid these complications, surgeons perform a partial stapled hemorrhoidopexy (PSH). The aim of this study is to present our early experience with the PSH. METHODS: We retrospectively reviewed the medical records of 58 patients with hemorrhoids who were treated with a PSH at Busan Hang-Un Hospital from January 2016 to June 2016. A specially designed tri-window anoscope was used, and a purse string suture was made at the mucosae of the protruding hemorrhoids through the window of the anoscope. The hemorrhoidopexy was done by using a circular stapler. RESULTS: Of the 58 patients included in this study, 34 were male and 24 were female patients (mean age, 50.4 years). The mean operation time was 12.4 minutes, and the mean postoperative hospital stay was 3.8 days. Three patients experienced bleeding (5.1%) 5 urinary retention (8.6%) and 5 skin tags (8.6%). Urge to defecate, tenesmus, abscess, rectovaginal fistula, anal stricture, incontinence, and recurrence did not occur. CONCLUSION: PSH is a minimally invasive, feasible, and safe technique for treating patients with grades III–IV hemorrhoids. A PSH, instead of a CSH, can be used to treat certain patients with hemorrhoids.

OBJECTIVE: To compare the pregnancy outcomes of in vitro fertilization (IVF) twins with those of spontaneous twins based on their chorionicities. METHODS: We performed a retrospective analysis of 598 twin pregnancies beyond 24 weeks of gestation delivered from October 1994 to December 2003. Subjects were grouped into the spontaneous group (n=392) and the IVF group (n=206) and then subgrouped into dichorionic (n=193, spontaneous vs. n=156, IVF) and monochorionic (n=154, spontaneous vs. n=34, IVF) subgroups. First, the obstetric and perinatal outcomes were compared between the spontaneous group and the IVF group regardless of their chorionicity. Second, the same outcome variables were compared between the spontaneous and the IVF group with same chorionicity. RESULTS: There was a significant increase in the incidence of preterm deliveries before 37 weeks of gestation in IVF twins (74.5% spontaneous vs. 82.5% IVF, p=0.031). However, the gestational age at delivery was not significantly different (34.5+/-2.86 weeks vs. 34.2+/-0.28 weeks). Antepartum admission was also significantly increased in IVF group (4.6% vs. 9.2%, p<0.001). We were unable to observe any significant difference in perinatal outcomes between the two groups other than increased in utero fetal demise in utero in the IVF group (0.3% vs. 1.5%, p<0.05). When we reanalyzed pregnancy outcomes based on chorionicity, there were more frequent admission to neonatal intensive care unit (42.7% vs. 52.6%, p<0.05) and necrotizing enterocolitis (0.5% vs. 3.5%, p<0.05) in dichorionic twins of the IVF group. In monochorionic twins, the incidence of placenta previa was increased in the IVF twin group (0% vs. 11.8%, p<0.001). CONCLUSION: In the IVF twins, the incidence of placenta previa was increased in monochrionic twins and the incidence of neonatal intensive care unit admission and necrotizing enterocolitis were also increased in dichorionic twins.
