We herein describe a case of a 55-year-old healthy woman with localized primary thymic amyloidosis presented as a mediastinal mass, found incidentally by chest radiography. Computed tomography revealed a 4.1 cm soft tissue lesion with nodular calcification in the left anterior mediastinum. The resected specimen was a well-defined lobulating mass with calcification. Microscopically, the mass was consisted of amorphous eosinophilc hyalinized substances involving the thymus and intrathymic lymph nodes. These eosinophilic substances showed apple-green bi-refringence under polarized light after staining with Congo red. In immunohistochemical study, they were positive for kappa and lambda light chains and negative for amyloid A. There was no evidence of systemic amyloidosis in clinical investigations. A final diagnosis of localized primary thymic amyloidosis was made.

PURPOSE: The clinical significance of preoperative serum levels of CEA and CA19-9, levels of CEA and CA19-9 in peritoneal washing fluid and free cancer cells in peritoneal washing fluid in gastric cancer patients were evaluated in this study. MATERIALS AND METHODS: Serum and peritoneal levels of CEA and CA19-9 and peritoneal washing cytology in 115 patients with gastric cancer were analyzed with respect to the prognostic factors using univariate and multivariate analysis. RESULTS: Positive rate of serum CEA and CA19-9 was 16.5%, 13.0%. And that of peritoneal washing CEA, CA19-9 and cytology was 15.7%, 7.8% and 9.6%. A univariate analysis showed that tumor markets in serum and peritoneal washing fluid and peritoneal washing cytology had significant correlations with the progression of the tumors, and patients with positive serum or peritoneal tumor markers had poorer survival after operation than did the patients with negative tumor markers. But in a multivariate analysis showed that only peritoneal CA19-9 was an independent risk factor. And combination of these five markers provided rnore predictable prognostic informations in a multivariate analysis. CONCLUSION: Combination of serum or peritoneal levels of CEA, CA19-9 and washing cytology appeared to be a useful marker for managing gastric cancer patients.

This is an autopsy-verifed case of the generalized cytomegalic inclusion disease occuring in a male fetus of a weeks gestation. The fetus revealed hydrocephalus and focal necrosis of brain, focal subcapsular necrosis of liver, and the typical cytomegalic inclusion cells having large acidophilic intranuclear inclusions in the liver, brain, kidney, lung, adrenal gland, pancreas and chorionic villi. Prominent extramedullary hematopoiesis was noted in the liver and kidney. Immuohistochemical staining using anti-cytomegalovirus antibody revealed intranuclear or occasionally intracytoplasmic immunoreactivity in brain, liver, pancreas, lung, kidney, and intestine.

PURPOSE: Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. MATERIALS AND METHODS: The estimated number of patients required for this study was 100 for a period of 18 months. Inclusion criteria were histologically proven gastric adenocarcinoma treated with laparoscopic distal or total gastrectomy and Billroth II or Roux-en-Y reconstruction. The primary endpoint was the incidence of duodenal stump leakage within the first 30 postoperative days. The secondary endpoints were early postoperative outcomes until discharge. RESULTS: One hundred patients were enrolled between February 2016 and March 2017. The study groups consisted of 65 male and 35 female patients with a mean age (years) of 62.3. Of these, 63 (63%) patients had comorbidities. The mean number of retrieved lymph nodes was 38. The mean operation time was 145 minutes including 7.8 minutes of mean LARS time. There was no occurrence of duodenal stump leakage. Thirteen complications occurred, with one case of reoperation for splenic artery rupture and one case of mortality. CONCLUSIONS: Based on the results of this prospective phase II study, LARS can be safely performed in a short operation period without development of duodenal stump leakage. A future randomized prospective controlled trial is required to confirm the surgical benefit of LARS compared to non-LARS.

Background: Although an ambulatory surgical practice continues to increase, there is a few data exist about patient discharge criteria. This study was undertaken to evaluate the usefulness and safety of Aldrete PAR (postanesthetic recovery) score and modified PADSS (modified postaneathesia discharge scoring system) on ambulatory surgery patients for recovery in Korea. Methods: Demographic, anesthetic data, Aldrete PAR score and modified PADSS on 279 patients were recorded. The time to dicharge, from recovery room and postoperative complications were evaluated, also. Results: PAR score and modified PADSS are correlated to length of stay in ambulatory surgery center. 24hr after discharge, 16% patients complained postoperative complications. Pain was most frequent postoperative complication. The PAR score was correlated with the occurrence of the complication. Conclusion: PAR score and modified PADSS are useful scoring systems to evaluate patients and make a decision to discharge the patients from ambulatory surgery center in safe.

A total of 30 cases of cerebral gliomas, including 6 cases of low grade astrocytomas, 6 anaplasticastrocytoomas and l8 glioblastomas multiforme, was examined immunohistochemically to demonstrate the overexpression of mutant forms of p53 protein and to evaluate their relationships with histological subtypes. A p53 monoclonal antibody was applied to the routine formalin fixed, paraffin-embedded tissues for this study using microwave-assisted avidin-biotin method. Overexpression of p53 protein was identified in 4 out of 6 anaplastic astrocytomas (66.7%) and in l3 out of l8 glioblastomas multiforme (72.2%). No immunohistochemical positivity of p53 was found in adjacent normal brain tissue, gliosis and 6 cases of astrocytoma. These results suggest that overexpression of mutant p53 may be an important step in the development and progression of malignant astrocytoma, especially of the aggressive subtypes of glioma, including glioblastoma multiforme.

Tuberculosis remains a serious infectious disease with primary features of pulmonary manifestation in Korea. However, duodenal tuberculosis is rare in gastrointestinal cases of extrapulmonary tuberculosis. Here, we report a case of primary duodenal tuberculosis mistaken as a malignant tumor and diagnosed with QuantiFERON-TB GOLD (Cellestis Ltd.) in an immunocompetent male patient.

SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome designates a group of articular and osseous manifestations frequently combined with skin disorders. Its fundamental component is inflammatory, pseudoinfectious, and sterile osteitis. The anterior chest wall is the most frequent localization and all the components of this structure may be involved. Palmoplantar pustulosis, psoriasis, acne conglobata, acne ulcerans, acne fulminans, pyoderma gangrenosum can be associated with the characteristic bone lesions. We report two cases of SAPHO syndrome : A 40-year-old female presented with both buttock pain with hyperostosis, costochondritis, synovitis and pustulosis palmaris and a 23-year-old male presented with migrating polyarthritis with costochondritis, synovitis, acne, pustulosis.
