Fine needle aspiration of the breast is an important diagnostic tool in malignant lesions, but is also useful in differentiation of inflammatory breast diseases mimicking carcinoma clinically and radiologically. Recently, the authors have experienced eight biopsy-proven cases of chronic inflammatory diseases of the breast, which consisted of 4 cases of duct ectasia, 2 cases of fat necrosis, and a case of tuberculous mastitis and granulomatous mastitis respectively, Their cytoiogic features mainly based on the components and the relative frequency of inflammatory cells were evaluated for differential diagnosis of chronic inflammatory breast diseases. The results are as follows ; 1. In cases of duct ectasia, varying amount of neutrophils, mononuclear leukocytes, histiocytes and multinucleated giant cells were intermixed with benign epithelial cell clusters. 2, Abundant fat tissue fragments were diagnostic for fat necrosis. Histiocytes and mononuclear cells were main components but not rich, and neutrophils and giant cells were infrequently observed. 3. Characteristic granulomas composed of epithelioid cells, mononuclear leukocytes and Langhans' type giant cells and lymphocytic infiltrates were conspicuous in tuberculous mastitis, and occasionally neutrophils, necrotic materials and epithelial cell clusters were found. 4. In granulomatous mastitis, epithelioid cell granulomas were also noted but numerous neutrophils and histiocytes were intermingled within or outside the granulomas.

In a six-year period(1988. 5-1994. 4), fine needle aspiration cytology(FNAC) of 322 pulmonary lesions from 296 patients were performed at Soonchunhyang University Hospital. Of these 322, malignancy was diagnosed cytologically in 139(43.2%), suspicious malignancy in 7(2.2%), negative in 164(50.8%), and insufficient material in 12(3.8%). Malignant lesions consisted of 54 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 18 cases of small cell carcinoma. They were verified by histologic examination in 70 cases. There were 2(0.6%) false positive cases due to florid bronchoalveolar hyperplasia and atypical bronchial epithelial cells associated with granulomatous lesion. The overall accuracy rate was 90%, the sensitivity 84.3% and the specificity 94.7%.

Background: White matter hyperintensity (WMH) is a risk factor for dementia and ischemic stroke. The atherogenic index of plasma (AIP) is a simple and cost-effective marker for the prediction of various vascular diseases. In this study, we evaluated the relationship between AIP and WMH in adults without cerebrovascular accidents. Methods: We analyzed the data of 281 adults, aged ≥26 years, who underwent brain magnetic resonance imaging (MRI) at the health promotion center of an education hospital between January 2014 and December 2018. Participants were divided into three categories according to tertiles of the AIP scores (T1: <0.20; T2: 0.20–0.48; and T3: >0.48). WMH was defined as a modified Fazekas scale score of 1–3 on brain MRI. A cubic spline curve was used to determine the linearity of the relationship between AIP and WMH. Multiple logistic regression analysis was used to evaluate the relationship between the AIP and WMH. Results: The prevalence of WMH was 45.7% in T1, 57.0% in T2, and 66.0% in T3 (T3 vs. T1, P for post-hoc analysis=0.005). The increased odds of WMH were associated with increased AIP. The odds ratio (OR) with a 95% confidence interval (CI) for WMH of T2 and T3 compared with T1 were 1.57 (0.88–2.80) and 2.30 (1.28–4.14), respectively. After adjusting for confounding variables, the OR with a 95% CI for WMH in the T2 and T3 groups vs. the referent T1 were 1.55 (0.76–3.13) and 2.27 (1.06–4.84), respectively. Conclusion AIP is independently and positively associated with WMH in a healthy population.

PURPOSE: The aim of this study was conducted to investigate the mean nRBC count in very low births weight infants (VLBWIs) and to determine the usefulness of the nRBC as an independent prognostic factors of perinatal complications in VLBWIs. METHODS: This study was conducted on 112 VLBWIs who were hospitalized in the neonatal intensive care unit (NICU) of the author's hospital within the period from March 2003 to and May 2008. Based on the infants' nucleated red blood cells (nRBC) counts at birth, on the third day after birth, on the seventh day after birth, in the second week after birth, and in the fourth week after birth in the medical records, the correlation between nRBC or absolute nRBC counts with birth weight, gestational age, and other perinatal outcomes were retrospectively investigated. RESULTS: In VLBWIs, their mean nRBC and absolute nRBC counts were showing a gradual decrease after birth, and they were consisteantly kept at low values since one week after and inversely proportional to the birth weights. The mean nRBC counts based on the stage after birth showed a significant correlation with perinatal death, necrotizing enterocolitis, and severe intraventricular hemorrhage. CONCLUSION: The increase in the nRBC count showed a significant correlation with having a severe intraventricular hemorrhage, necrotizing enterocolitis, and perinatal death in VLBWIs. If an increase or no decrease in the nRBC count after birth is observed, newborn-infant care precautions should be required.

OBJECTIVE: Destructions of vertebral body due to various etiologies including acute fracture, tumor, post-traumatic deformity and infection lead to progressive destruction of vertebral body, kyphotic deformities and further neurological deficits. Titanium mesh cages (TMCs) with cancellous autograft bone after corpectomy of the thoracolumbar spine provide immediate structural support to the anterior column. The aim of this study is to evaluate the radiological, neurological and clinical outcomes of patients with the TMCs-bone graft composite after thoracolumbar corpectomy. METHODS: Sixteen patients underwent reconstruction using titanium mesh cages in thoracolumbar corpectomy between July 2000 and February 2005. The radiological and clinical course was documented over a mean follow up duration of 28.2 months. The degree of kyphosis, construct height and the subsidence of the cage in relation to the vertebral endplates were measured preoperatively, early postoperatively, and at the latest follow up. RESULT: The mean kyphotic angle of 3.9degrees before surgery was reduced to -2.6degrees immediately after surgery, and at the last follow up to be 3.4degrees. There was a significant difference between the preoperative versus postoperative kyphotic angle (p=0.003). The mean construct height of involved vertebra before surgery was 41.6 mm and the mean construct height immediate after surgery and at follow up were 47.9 mm and 41.5 mm, respectively. There was a significant difference between the preoperative versus postoperative construct height (p<0.0001). But there was no significant difference between the preoperative versus follow up in kyphotic angle and construct height. The mean subsidence was 5.7 mm. However, there was no case of severe collapse or significant recurrence of deformity. All patients had not attained significant neurological deterioration after surgery without major complications. CONCLUSION: In this study, TMCs after thoracolumbar corpectomy is a successful adjunct for anterior vertebral column reconstruction. In our cases, TMCs with anterior instrumentation alone allows a good structural support and maintain spinal alignment.

PURPOSE: Although there is an increasing incidence of upper third gastric cancers, the appropriate extent of resection for upper third gastric cancer is not known. This study was performed to analyze a 9-year experience with upper third gastric adenocarcinomas from one institution treated by either total gastrectomy (TG) or proximal gastrectomy (PG). METHODS: The records and survival data of 158 upper third gastric cancer patients who underwent curative TG (n=106) or PG (n=52) through an exclusively abdominal approach were retrospectively analyzed. RESULTS: There was no significant difference in age, sex, tumor gross type, tumor differentiation, and stage between the groups who underwent TG and those who underwent PG. In addition, there were no significant differences in hospital mortality, overall 5-year survival, and disease-free survival rates between PG and TG group. However, PG group showed higher rates of postoperative reflux esophagitis and anastomosis stricture than TG group. Regarding the main patterns of recurrence, local recurrence was dominant in PG group, whereas distant recurrence was dominant in TG group. CONCLUSION: The extent of resection for upper third gastric cancer does not affect long-term outcome, and both procedures can be accomplished safely. When the cancer is confined to upper third of the stomach without serosal invasion, PG combined with antireflux procedures can be indicated.

PURPOSE: We compared CT findings of thickened wall-type gallbladder cancer with those of complicated cholecystitis. MATERIALS AND METHODS: We retrospectively reviewed abdominal CT scans of ten patients with thickened wall-type gallbladder cancer and eight patients with complicated cholecystitis, from March 1991 to November 1995. RESULTS: CT findings of thickened wall-type gallbladder cancer showed diffuse or focal wallthickening. Wall thickness was 5.3-18.0 mm(mean value, 12.2mm ; n=10). Gallbladder wall thickness of complicatedcholecystitis was 3.0-14.0mm (mean value, 6.6mm ; n=8). Statistical significance was noted between thickened wall-type gallbladder cancer and complicated cholecytitis(p<0.0029). Irregular wall thickening was noted in 7/10cases of thickened wall-type gallbladder cancer(70%). Regular wall thickening was noted in 6/8 cases of complicated cholecystitis(75%). The luminal diameter of thickened wall-type gallbladder cancer was 3.3-5.4cm (meanvalue, 4.2cm ; n=10). The luminal diameter of complicated cholecystitis was 5.2-8.0cm (mean value, 6.5cm ; n=8).Statistical significance was noted between thickened wall-type gallbladder cancer and complicated cholecystitis(p<0.0003). The halo sign was noted in only 3/8 cases of complicated cholecystitis(38%). Secondary findings of thickened wall-type gallbladder caner was lymphadenopathy in 3/10 cases(30%), and liver invasion in 2/10 cases(20%). Secondary findings of complicated cholecystitis were liver abscess in 2/8 cases(25%), and RLQ abdominal fluid collection and pleural effusion in 4/8 cases(50%). CONCLUSION: Differential factors of thickened wall-type gallbladder cancer from complicated cholecystits are gallbladder wall thickness, regularity of wall thickness, halo sign, secondary findings and luminal distention.

We examined the interrelationships of depth of penetration, tumor size, and the number of positive lymph nodes in Dukes'c colorectal cancer. This report contains a retrospective study of 256 cases of colorectal cancer that underwent treatment from Jan. 1985 to Dec. 1994 at the Department of Surgery, Kangbuk Samsung Hospital. The most of the patients were on the 6th decades and male to female ratio was 1.27 : 1. By modified Astler-Coller classification, there were stage Cl 29 cases(11.3%), C2 227 cases(88.7%). Eighty patients with colon cancer(31.4%) and 176 patients with carcinoma of the rectum(68.6%) were available for analysis. Utilizing cumulative frequency distributions of tumor size, depth of invasion and the number of positive lymph nodes, comparisons were carried out among three factors. The results indicate that there was no correlation between the longest diameter of the tumor and other two factors but the number of positive lymph node was closely related to depth of invasion. In conclusion, the number of positive lymph node and depth of invasion are very important prognostic factor. But tumor size as a single factor does not correlated with prognosis in Dukes' C colorectal cancer.

Retrospective analysis of reoperation and complication was made for 186 patients with lumbar herniated disc. The results showed complication rate of 7%(13 cases) and reoperation rate of 10.2%(19 cases). The primary complications were infections(9 cases), technical errors(2 cases), and scores(2 cases). Rate of discitis was 1.6%(3 cases). The outcomes of reoperation resulted in excellent recovery of 16%(3 cases) and good recovery of 58%(11 cases). The most common intraoperative findings of reoperation were inadequate disectomy or missed disc fragments 31.6% or 6 cases;epidural fibrosis 26.3% or 5 cases;and new herniation at other level 15.8% or 3 cases. Excellent and good results could be achieved in patients operated within 1 month or more than 6 months after while the patients who underwent reoperation between 1 month and 6 months showed poor results. The delicate perioperative menagement and complete discectomy, adequate bleeding control and laminectomy were considered to be essential in reducing the chance of complication and reoperation.
