The presence and distribution of pan-neuroendocrine markers such as neuron-specific enolase (NSE), chromogranin (CG), and synaptophysin (SYP) were investigated by immunohistochemistry in 15 cases of neuroblastic tumors, including four cases of neuroblastomas, six cases of ganglioneuroblastomas, and five cases of ganglioneuromas. Three cases of normal sympathetic ganglion were used for the normal control group. NSE was observed in all cases and both in ganglion cells and in neuropils. NSE was detected not only in the majority of the neuroblasts showing signs of differentiation, but also in some poorly differentiated neuroblasts. All cases of neuroblastic tumors were positive for CG, however, some variability of staining intensity and distribution patterns were noted. CG was found mainly in differentiated neuroblasts with enlarged cytoplasm and nuclei along the periphery of the perikaria, and was also found in the perinuclear regions of some undifferentiated cells. SYP was positive in 9 of 11 cases. In all of the 9 cases, SYP was detected in some differentiating neuroblasts and differentiated neuroblasts, as well as the mature ganglion cells. However, it has scarcely stained in dot or granular pattern. Two CG-negative tumors were also negative for SYP. Our data indicate that antibodies against NSE and CG are helpful as a diagnostic aid for neuroblastic tumors.

The contour of mandibular angle is important for facial esthetics in the oriental population, because the wide and square face is thought to have had an unhappy life. A prominent mandibular angle produces a characteristics quardrangle, coase, and muscular appearance. So, uni- or bi-lateral mandibular angle reduction is usually performed. However, there is little guideline for bi-lateral angle reduction. So, this study was to investigate the pattern of Korean mandibular angle for bi-lateral mandibular angle reduction as guideline. This study was included 66 adult men and women over 19 years old who are having the normal mandibular angle. We measured the posterior border, angle, and inferior border of mandible using cephalometric view. The results of study was as followed : 1. The ratio of posterior mandible was 96.6, 97.3% in male, and 103.0, 106.0% in female. 2. The ratio of mandibular angle(R1-Go/R1-R2) was 120.2% in male, and 117.3% in female. 3. The ratio of inferior mandible(D5, 6, 7, E, F, G/D4) was 97. 3, 90.9, 79.5, 65.2, 57.8, 46.9% in male, and 98.5, 91.2, 80.5, 67.6, 59.1, 50.2 % in female. The results of this study should be useful to decide accurate amount of reduction.

The diagnosis of acute pancreatitis occurred in CAPD patients is quite difficult due to its clinical similarity with acute peritonitis. Delayed diagnosis and treatment of acute pancreatitis in CAPD patients may result in fatal complication. We experienced a case of acute pancreatitis in a CAPD patient. A 62 years old female visited the hospital with acute abdominal pain and cloudy effluent for 3 days. She has been on CAPD for 3 years and had two episodes of peritonitis at 6 months and 1 year before the admission. The causative organism was Streptococcus viridans in each episode. The peritonitis symptoms and peritoneal leukocyte count incresed despite of using Vancomycin(R) and Netilmicin(R). Causative organism was not isolated from dialysis. Serum amylase concentrations increased from 105mg/dL at the admission to 1,052mg/dL on day 10 of admission. Abdominal ultrasonography and abdominal computerized tomogram revealed fat infiltration, focal necrosis and multiple cyst formation at pancreas area. Computerized tomogram guided aspiration cytology revealed acute inflammation and necrosis. Bacteria were not found in the aspirate. Clinical symptoms were improved after discontinuation of CAPD and intraperitoneal use of antibiotics. The patient restarted CAPD on the day 18 and remained without complications. We report this case with a brief review of literatures.

OBJECTIVES: Staphylococcal scalded skin syndrome (4S), a blistering dermatosis caused by exfoliative toxins from Staphylococcus aureus, occurs frequently in patients with atopic dermatitis (AD). However, association between 4S and AD has not rarely been reported. We investigated the characteristics of 4S according to AD status.METHODS: The study included 146 children with 4S who visited Busan St. Mary's Hospital from 2007–2018. Clinical features were analyzed from medical records and pictures, and 4S was classified as localized or generalized. We also retrospectively investigated the preceding conditions and test results related to AD.RESULTS: Among 146 patients with 4S, median age was 2.0 years, and 35 (24.0%) had AD. Since 2007, the incidence of both 4S and AD have increased, without obvious seasonal patterns. Generalized and localized disease occurred in 90 and 56 patients, respectively. Twenty-four of 35 patients with AD (68.6%) and 32 of 111 (28.8%) without AD had localized disease. Significant differences were observed between the groups (P = 0.000). Among those with AD, the most common preceding condition was skin infection or unknown (45.2%); however, respiratory disease was the most common (47.9%) among patients without AD. Eosinophil levels were higher in the AD group (P = 0.002), and there were no statistically significant differences in total immunoglobulin E (IgE), Dermatophagoides farinae (Df IgE), egg-white IgE, and culture results between the groups.CONCLUSIONS: Localized 4S frequently occurred without preceding conditions in children with AD and usually arose from skin infection compared to generalized 4S.

PURPOSE: To investigate how the effect of bilateral rectus muscle recession changed by analyzing the effect/dose ratio of surgery according to the preoperative angle deviation.METHODS: We retrospectively studied the medical records of patients from January 2007 to March 2014 who underwent bilateral lateral rectus muscle recession and who visited our hospital for at least 2 years after surgery. We classified the patients into two groups: the preoperative large angle deviation group (35 prism diopters [PD] or more) and the small angle deviation group (20 PD or less). We observed exodrift patterns by measuring distant and near angle deviation according to the preoperative and postoperative times. The effect/dose ratio of recession was calculated at each visit. Surgical success was defined as an alignment between 10 PD of exodeviation and 5 PD of esodeviation, both at distance and at near.RESULTS: Among 165 patients, 84 patients were in the large angle deviation group and 81 patients were in the small angle deviation group. Preoperative angle deviation of the large angle deviation group was 39.34 ± 5.13 PD (range: 35–55 PD) and the small angle deviation group was 19.49 ± 1.62 PD (range: 18-20 PD) (p < 0.001). At postoperative 1 day, the alignments of eyes of the two groups were −8.32 ± 9.31 PD and −13.11 ± 6.94 PD; p < 0.001, respectively. At the date of the final follow-up, the alignments of eyes of the two groups were 4.63 ± 8.94 PD and 1.22 ± 8.01 PD; p = 0.011, respectively, and the effect/dose ratios were 2.25 ± 0.62 PD/mm and 1.94 ± 0.78 PD/mm, respectively, which meant that the effect of correction for the large angle deviation group was larger than that of the small angle deviation group (p = 0.005). Both groups showed postoperative exodrift patterns and similar success rates (75.0% and 80.2%, respectively), which showed no significant difference (p = 0.268).CONCLUSIONS: The small angle deviation group showed a larger effect of correction and high exodrift pattern at the postoperative initial time and the large angle deviation group showed a smaller effect of correction and low exodrift pattern at the postoperative initial time. The preoperative angles of deviation and the operative success rates were not related.

PURPOSE: High-resolution ultrasound is a safe and costeffective method of identifying and characterizing thyroid nodules, and also for guiding aspiration cytology. But differentiating malignancy from the more frequently occurring benign thyroid nodules has proved challenging as there may be significant overlap in their sonographic appearance. The purpose of this study was to correlate the sonographic characteristics of thyroid nodules with the pathologic results after thyroidecotmy, and to establish the relative importance of these features for predicting the risk for malignancy. METHODS: We reviewed 516 thyroid nodules in 413 patients who underwent thyroidectomy between August 2003 and May 2005, after routine preoperative ultrasound. The following sonographic characteristics of the nodules were evaluated and we determined their sensitivity, specificity and positive predictive value: shape, margin, presence of halo, echo structure, internal echo, echogenicity, calcification and the type of vascularization. RESULTS: Of the 516 nodules, 327 were malignant nodules and 189 were benign nodules. The nodule size ranged from 5 to 80 mm at the greatest dimension (mean: 20.6 mm). The shape, margin, absence of halo, echo structure, and echogenecity showed statistically significant differences between the benign and malignant nodules in this study. Microcalcifications had low sensitivity but high specificity (13.1% vs 98.9%, respectively). Various combinations of features that have been suggested to be significant predictors of malignancy were also analyzed. The presence of all features was 100% specific for malignancy. According to the receiver operating characteristic curve, the best point for not over-looking malignancy is 2.5. At greater than this point, fine needle aspiration cytology is needed. CONCLUSION: This study has shown that ultrasonography is useful for differentiating between benign and malignant thyroid nodules and it can provide the proper indications for aspiration cytology.

PURPOSE: Anaplastic thyroid cancer (ATC) is a rare but highly aggressive neoplasm with a dismal prognosis. However, a few patients survive for a long time after treatment. We tried to identify prognostic factors of this disease and analyzed treatment outcomes in patients with ATC. METHODS: We reviewed the medical records of 15 patients diagnosed with ATC in our institution between 1988 and 2003. The survival was compared by the Kaplan-Meier logrank test using SPSS program. RESULTS: The female-to-male ratio was 1.5:1 (9 women and 6 men), and the mean age at diagnosis was 63.9 years (range, 44~91). The mean tumor size was 6.3 cm (range, 4~10 cm). Extrathyroidal invasion was present in 12 cases and distant metastasis at diagnosis was present in 6 cases. Surgery was performed in 8 cases. Radiotherapy was used for 10 cases and chemotherapy for 5 cases. The mean overall survival time of the 15 patients was 237 days (range, 28~717 days). The 6~, 12~, 18~ and 24~ month survival rates were 33%, 26%, 13% and 0%. No association was found between survival and presenting symptoms, age, gender, tumor size, previous goiter history, extrathyroidal invasion, distant metastasis, surgery, radiotherapy or chemotherapy. A significantly better outcome was observed in patients received triple modality treatment (surgery, radiotherapy and chemotherapy) than in those received single or dual modality treatment (P=0.05). CONCLUSION: Although most patients with ATC had a poor prognosis, a multimodal approach including surgery, radiotherapy and chemotherapy, might improve survival.

STUDY DESIGN: A retrospective study. PURPOSE: To assess the radiographic progression of degenerative lumbar scoliosis after short segment decompression and fusion without deformity correction. OVERVIEW OF LITERATURE: The aims of surgery in degenerative lumbar scoliosis are the relief of low back and leg pain along with a correction of the deformity. Short segment decompression and fusion can be performed to decrease the level of low back and leg pain provided the patient is not indicated for a deformity correction due to medical problems. In such circumstance, the patients and surgeon should be concerned with whether the scoliotic angle increases postoperatively. METHODS: Forty-seven patients who had undergone short segment decompression and fusion were evaluated. The average follow-up period was more than 3 years. The preoperative scoliotic angle and number of fusion segments was 13.6+/-3.9degrees and 2.3+/-0.5, respectively. The preoperative, postoperative and last follow-up scoliotic angles were compared and the time of progression of scoliotic angle was determined. RESULTS: The postoperative and last follow-up scoliotic angle was 10.4+/-2.3degrees and 12.1+/-3.6degrees, respectively. In eight patients, conversion to long segment fusion was required due to the rapid progression of the scoliotic angle that accelerated from 6 to 9 months after the primary surgery. The postoperative scoliosis aggravated rapidly when the preoperative scoliotic angle was larger and the fusion was extended to the apical vertebra. CONCLUSIONS: The scoliotic angle after short segment decompression and fusion was not deteriorated seriously in degenerative lumbar scoliosis. A larger scoliotic angle and fusion to the apical vertebra are significant risk factors for the acceleration of degenerative lumbar scoliosis.
