Correlation between clinical symptoms and magnetic resonance imaging findings in patients with temporomandibular joint internal derangement

OBJECTIVES: The purpose of this study was to clarify which findings in magnetic resonance imaging (MRI) are good predicators of pain and mouth opening limitation in patients with temporomandibular joint (TMJ) internal derangement (ID). MATERIALS AND METHODS: Clinical examinations for pain and mouth opening limitation were conducted for suspected TMJ ID. MRI scans were taken within a week of clinical examinations. On the oblique-sagittal plane image, readings were obtained in terms of the functional aspect of disc position, degree of displacement, disc deformity, joint effusion, and osteoarthrosis. Multiple logistic regression analyses were conducted to identify the predictors of pain and mouth opening limitation. RESULTS: A total of 48 patients (96 TMJs) were studied, including 39 female patients and 9 male patients whose ages ranged from 10 to 65 years. The resultant data showed significant correlations between pain and the MR imaging of the degree of disc displacement (P<0.05). The probability of there being pain in moderate to significant cases was 9.69 times higher than in normal cases. No significant correlation was found between mouth opening limitation and MRI findings. CONCLUSION: We identified a significant correlation between clinical symptoms and MRI findings of ID. The degree of anterior disc displacement may be useful for predicting pain in patients with TMJ ID.

Simultaneous Glossectomy with Orthognathic Surgery for Mandibular Prognathism / 대한악안면성형재건외과학회지

Macroglossia can create dental and skeletal instability after orthodontic treatment or orthognathic surgery for mandibular prognathism. In relevant literature, partial glossectomy is suggested for a good post-treatment prognosis. Most of the published partial glossectomy cases are two-staged surgery, because of concern about postoperative airway obstruction. As orthognathic surgical techniques and fixation method develop, however, concerns about postoperative airway obstruction have lessened. In this case, mandibular setback surgery and partial glossectomy were performed simultaneously, leading to stable recovery without any postoperative respiratory problems. After surgical technique to preserve the tongue tip, we achieved good outcomes without postoperative side effects of lingual hypoesthesia, pronunciation disorder and dyskinesia. We report this case with a literature review.

A Case of Peritoneal Inclusion Cyst caused by Chlamydia Trachomatis Infection / 대한산부인과학회지

Peritoneal inclusion cysts are fluid collections among adhesions occurring after an inflammatory process in the peritoneal cavity or after an operation. The typical ultrasound morphology of a peritoneal inclusion cyst is that of a cystic mass following the contours of the pelvis, and with a deformed ovary suspended among adhesions centrally or peripherally in the cyst, and the cyst may contain both septa and papillary projection. So sometimes it is difficult to distinguish an ovarian mass from peritoneal inclusion cyst. We experienced one case of huge peritoneal inclusion cyst caused by chlamydia trachomatis infection and then we report it together with a brief review of literatures.

A case of prenatally diagnosed Non-15, Non-22 marker chromosome / 대한산부인과학회지

Midtrimester genetic amniocentesis is an important diagnostic tool in prenatal genetic diagnosis and counseling. We can identify karyotypes with metaphase chromosome analysis of cultured amniocytes. Marker chromosomes are defined as unidentified structurally abnormal chromosomes. Incidence of marker chromosomes in the previous reported studies was 0.6-1.5/1,000. They occurred more frequently with advanced maternal age. Ascertainment of chromosomal origin is important because it may be associated with malformation and developmental abnormalities. Recently, identification of the origin and composition of marker chromosomes has been made possible by the use of fluorescent in situ hybridization (FISH). Most marker chromosomes are known to be originated from chromosome 15 or 22, X, Y. We have experienced a case of non-15, non-22 marker chromosome prenatally detected in amniocentesis and FISH, so we reported it with a brief review of literature.

A clinical evaluation of chlamydia trachomatis infection in women with pelvic inflammatory disease / 대한산부인과학회지

OBJECTIVE: Chlamydia trachomatis is one of the most common causative microorganism in pelvic inflammatory disease (PID). In this infection tubal obstruction, infertility, tubal pregnancy and recurrent pelvic infection has involved. Also, perinatal infection, spontaneous abortion and preterm labor of pregnant women increased in chlamydia infection. This study was performed to investigate the prevalence rate and clinical characteristics of Chlamydia trachomatis in symptomatic women. METHODS: From March, 2003 to March, 2004, in OB-Gyn development, endocervical swab were obtained in 218 patients (137 impatients of PID and 81 outpatients) by Amplicor Chlamydia Transfer Kits and Human papilloma virus kit. They were studied on history taking, physical examination, laboratory test, and polymerase chain reaction for the detection of Chlamydia trachomatis. Also, in this study we investigated the prevalence of human papilloma virus and N. gonorrhea in the Chlamydia infection group. RESULTS: The prevalence rate of Chlamydia trachomatis was 27.5% (61/218) in pelvic inflammatory disease. As regarding the age distribution of Chlamydia trachomatis positive group was the high prevalence rate in twenties (52.8%). Chlamydia infection was related to the history of artificial abortion, oral contraception, occupation status, history of gynecologic disease (PID, Ectopic pregnancy). Women with chlamydial infection were 2.5 times greater risk of coincidal HPV infection and 2 times greater risk of coincidal N. gonorrhea infection and both were statistically significant. CONCLUSION: The prevalence rate of Chlamydia infection is higher than any other sexually transmitted disease and Chlamydia infection has serious complication on reproduction. It appears weak symptom and detection is difficult. Therefore the screening and treatment of Chlamydia trachomatis are necessary to decrease the prevalence and prevention of complication.

Apoptosis Induced by Manganese in Basal Ganglia Primary Neuronal Cell Culture: Morphological Findings / 대한산업의학회지

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

Intraperitoneal and Retroperitoneal Sarcomas / 대한암학회지

PURPOSE: Sarcomas arising in intraperitaneal cavity and retroperitoneal space are relatively uncommon. Thus, studies characterizing the results of long-term follow-up are limited. The purpose of this study was to identify the clinicopathologic features and prognostic factors of intraperitoneal and retroperitoneal sarcomas. Materials and Method: Thirtyeight patients with intraperitaneal or retroperitoneal sarcoma who had been treated at Department of Surgery, Korea Cancer Center Hospital during the period from January 1987 to December 1997 were reviewed retrospectively. RESULTS: The ratio between male to female was 0.9: 1. The mean age of the patients was 48.3 (32-75) years. The most common symptom was abdominal pain or discomfort (61%), followed by palpable mass (55%), GI bleeding (34%), weight loss (26%), and change of bowel habits (21%). The most comman histologic type was leiomyosarcoma (73.7%), followed by liposarcoma (23.7%), and malignant fibrous histiocytoma (2.6%). The mean tumor size was 15.5 x12.1 x 8.7 cm. Among 38 cases, 25 cases developed in intraperitoneal cavity and 13 cases arose in retroperitoneal space. Overall, 44 operations were performed in 31 patients. Among them, complete surgical resection constituted 73%. In 20 cases, combined resection of adjacent organ was performed to accomplish complete surgical resection of tumors. During the median follow up period of 23 months (3~116 months), the overall 5-year survival rate was 34.7%. The patients who had been treated by complete surgical resection showed better survival than those in whom palliative resection or biopsy only was performed (38.6% vs 0% of 5 YSR, P=0.015). Liposarcoma showed better prognosis than leiomyosarcoma (41.7% vs 34.2% of 5 YSR, P=0.0000). The size of tumor (10 cm>vs 10 cm< or =) was not a statistically significant prognostic factor. CONCLUSION: In this series, The histologic type and complete surgical resection were important factors that can affect the survival of the patients. Aggressive surgical resections are therefore wananted to obtain better outcome of the patients with intraperitoneal and retroperitoneal sarcomas.
