Objective: This study aimed to retrospectively analyze the prevalence of orthodontic problems and the proportion of patients who underwent orthodontic diagnosis among children aged 6 (n = 300), 7 (n = 400), and 8 (n = 400) years who had undergone panoramic radiography. Methods: Children were divided into five groups according to their chief complaint and consultation: conservative dentistry, oral and maxillofacial surgery, orthodontics, periodontics, and prosthodontics). Chief complaints investigated included first molar eruption, lack of space for incisor eruption, frequency of eruption problems, lack of space, impaction, supernumerary teeth (SNT), missing teeth, and ectropion eruption.The number of patients whose chief complaint was not related to orthodontics but had dental problems requiring orthodontic treatment was counted. The proportion of patients with orthodontic problems who received an orthodontic diagnosis was also examined. Results: Dental trauma and SNT were the most frequent chief complaints among the children. The proportion of patients with orthodontic problems increased with age. However, the orthodontic diagnosis rates based on panoramic radiographs among children aged 6, 7, 8 years were only 1.5% (6 years) and 23% (7 and 8 years). Conclusions Accurate information should be provided to patient caregivers to correct misconceptions regarding the appropriateness of delaying orthodontic examination until permanent dentition is established.

OBJECTIVE: The measurement of tumor-associated antigen as tumor makers in the serum is useful for early diagnosis, differential diagnosis, and the determination of remission after therapy in cases of malignancy. A tumor-associated antigen is not always present in all the cells forming the tumor and also be detected in other tumors or normal organs. Tissue polypeptide antigen (TPA) is a single polypeptide chain without carbohydrate. TPA has immunosuppresive properties in patients with cancer. The aim of this study was to evaluate the clinical usefulness of the cytokeratin tumor marker TPA in early diagnosis of patients with the gynecologic cancer. METHODS: In this study, the levels of TPA were measured in the serum of 61 patients with benign gynecologic tumors, 24 patients with malignant gynecologic neoplasms, and 38 healthy nonpregnant females. Serum TPA level was measured by a "sandwitch technique based" radioimmunoassay. RESULTS: As a result, serum TPA level was 30.4+/-7.6 U/L in control group, 32.6+/-9.4 U/L in benign gynecologic tumor group, 39.1+/-9.8 U/L in malignant gynecologic neoplasm. Serum TPA level was 56.6+/-7.0 U/L in ovarian cancer group. CONCLUSION: Serum levels of TPA was increased in the ovarian cancer group, but it does not seem to be a useful tumor maker for non-ovarian cancer. It would seem that measurement of TPA is useful for early diagnosis of ovarian cancer.

Aplasia cutis congenita (ACC) is an uncommon condition which is characterized by congenital, localized or widespread absence of skin or scar formation. Lesions can be multiple and may occur on any body surface, although they are mostly seen on the scalp as a solitary lesion. ACC is most often a benign isolated defect; but it can be associated with other physical anomalies or malformation syndromes. Adams-Oliver syndrome is a distinct subtype in which distal limb reduction is found in association with a solitary scalp defect. There is no single underlying cause of ACC; it may reflect a disruption of intrauterine skin development. A 25 day-old boy was referred to our clinic with a thick hemorrhagic crust, and a surrounding hairless atrophic scar on the midline over the skull vertex. He also had hypoplasia of the left 2nd to 5th toes since birth. The rest of the physical examination as well as an ultrasound examination of the brain were normal. Herein we report a rare case of ACC of the scalp accompanied by distal limb hypoplasia, Adamson-Oliver syndrome.

PURPOSE: This study aimed to compare the accuracy (trueness and precision) of interim crowns fabricated using DLP (digital light processing) according to postcuring time. MATERIALS AND METHODS: A virtual stone study die of the upper right first molar was created using a dental laboratory scanner. After designing interim crowns on the virtual study die and saving them as Standard Triangulated Language files, 30 interim crowns were fabricated using a DLP-type 3D printer. Additively manufactured interim crowns were post-cured using three different time conditions-10-minute post-curing interim crown (10-MPCI), 20-minute postcuring interim crown (20-MPCI), and 30-minute post-curing interim crown (30-MPCI) (n = 10 per group). The scan data of the external and intaglio surfaces were overlapped with reference crown data, and trueness was measured using the best-fit alignment method. In the external and intaglio surface groups (n = 45 per group), precision was measured using a combination formula exclusive to scan data (10 C2). Significant differences in accuracy (trueness and precision) data were analyzed using the Kruskal-Wallis H test, and post hoc analysis was performed using the Mann-Whitney U test with Bonferroni correction (α=.05). RESULTS: In the 10-MPCI, 20-MPCI, and 30-MPCI groups, there was a statistically significant difference in the accuracy of the external and intaglio surfaces (P <.05). On the external and intaglio surfaces, the root mean square (RMS) values of trueness and precision were the lowest in the 10-MPCI group. CONCLUSION Interim crowns with 10-minute post-curing showed high accuracy.

BACKGROUND: A variety of dermatological disorders develop in hospitalized patients and the need for dermatological consultations is on the rise. OBJECTIVE: We analyzed 2 years of dermatological consultation data from a tertiary medical center in Korea and compared dermatological problems among individual departments. METHODS: We reviewed 3,102 dermatological inpatient consultations by performing a retrospective chart review. RESULTS: Contact dermatitis (11.4%), drug eruption (9.6%), tinea pedis (5.5%), xerotic eczema (5.3%), and seborrheic dermatitis (5.2%) were the 5 dermatological disorders that were most commonly referred to dermatologists. Patients in the allergy and pulmonology departments had higher rates of drug eruptions. Endocrinology-admitted patients, especially diabetic patients, frequently complained of foot dermatitis. The cardiology, gastroenterology, and hemato-oncology departments referred many patients with purpuric dermatosis to dermatologists. Patients from the surgical departments consulted more frequently consulted contact dermatitis and drug eruptions. The neurology and rehabilitation medicine departments referred more seborrheic dermatitis patients than other departments. Pediatric patients commonly consulted for atopic dermatitis, viral exanthemata, and seborrheic dermatitis. Regardless of department, patients who suffered from severe illness and underwent major surgery developed herpes zoster and cutaneous fungal infections more frequently than other patients. Personal hygiene was closely related to the development of follicular disorders. CONCLUSION: Dermatologists should be familiar with the diverse dermatological complaints of patients admitted to various departments and be actively involved in the diagnosis, treatment, and education of doctors and patients to improve the quality of inpatient care.

PURPOSE: When combined with surgery, neoadjuvant hormonal therapy (NHT) has not demonstrated a significant benefit for meaningful clinical endpoints such as progression-free survival or overall survival. We evaluated the effect of NHT on prostate cancer. MATERIALS AND METHODS: From 1995 to 2004, 519 patients underwent radical retropubic prostatectomy(RRP). One-hundred thirty of them were included in this retrospective case-control study and they were assessed for age, the preoperative prostate-specific antigen(PSA) level, the clinical stage and the biopsy Gleason score(GS). The subjects were divided into two groups: the RRP only group(n=65) and the NHT group(n=65), and these were matched for the 3 above mentioned parameters. The protocols for NHT were maximal androgen blockade(n=40), antiandrogen only(n=8), and LHRH analogue only(n=17). Biochemical recurrence was defined as a level of serum PSA of 0.2ng/ml or greater on 2 consecutive evaluations. RESULTS: The mean age of the RRP only group and the NHT group was 64.2 and 63.5, respectively(p>0.05). The rates of a positive surgical margin and biochemical recurrence in the NHT group were 49.2% and 42.5%, respectively, and they were 46.2% and 46.2%, respectively, in RRP only group, and there was no statistical difference between the two groups. In high risk patients(clinical stage> or =T3, biopsy GS> or =8, serum PSA>20ng/ml), NHT group was not differences compared with the RRP group. Neither the duration (3 months vs. 6 months) of NHT nor the regimens of NHT improved the clinical and surgical outcome. CONCLUSIONS: NHT did not improve biochemical recurrence and the positive surgical margin.
