PURPOSE: Whole body Positron Emission Tomography (PET) was used to evaluate the existence of cancer cells. However, PET had limitations in identifying thyroid cancer cells because of their slow progression, and evidence regarding its accuracy in finding thyroid cancer cells is insufficient. Therefore, we investigated the usefulness of PET for evaluation of patients with thyroid nodules by studying the relationships between PET and thyroid ultrasonography. METHODS: We evaluated 4,627 patients who had undergone PET from January 2007 to October 2011 and selected 370 patients who had undergone thyroid ultrasonography. We compared and analyzed the amount of thyroid SUVmax of PET, the pattern of glucose uptake, and findings of thyroid ultrasonography based on their size, shape, location, and FNAC. RESULTS: Of 370 patients, 197 (53.2%) subjects were found to have thyroid nodules, and 211 (57.0%) subjects had higher sugar metabolism, regardless of having thyroid nodules. No statistical correlations were observed among nodule size, nodule location,and higher sugar metabolism, however, noticeable relationships were observed between the shape of the cells on thyroid ultrasonography and FDG uptake of PET. In cases of papillary thyroid cancer, there was higher FDG uptake, compared to benign lesions in particular, SUVmax of the papillary thyroid cancer showed a significantly elevated level of FDG uptake. CONCLUSION: Despite its limited usefulness in identifying the characteristics of thyroid nodules being benign or malignant, PET is appropriate for evaluation of the malignancy of thyroid cells

PURPOSE: Colonic diverticulitis is an uncommon disease in Korea, but the incidence of the disease is increasing. The right colon is the more preferred site for diverticulitis in Korea, but the incidence of left diverticulitis is increasing. Therefore, comparing the clinical features and treatments for right diverticulitis with those for left diverticulitis may help us to treat the disease more properly. METHODS: This study was performed retrospectively by reviewing the medical records of 96 patients with colonic diverticulitis, in whom either conservative or operative treatments were performed. RESULTS: Eighty-six patients had right diverticulitis (RD), and 10 patients had left diverticulitis (LD). The mean age of the patients was older for LD. Sixteen patients (18.6%) with RD had complications, and 7 patients (8.1%) underwent operations. On the other hand, 4 patients (40%) with LD had complications, and 3 patients (30%) underwent operations. The rates of complications and operations among old-aged patients were higher. The operations for 7 patients with RD who underwent surgery were 6 ileocecectomies and 1 diverticulectomy. On the other hand, the operations for the 3 patients with LD who underwent surgery were 2 resections and anastomoses and 1 diverticulectomy. The reasons for the operations were abscess formation, recurrence, perforation, and development of generalized peritonitis without response to conservative treatment. CONCLUSION: The incidence of LD is lower than that of RD in Korea, but the rate of complications and operations seems higher in LD. Therefore, patients who complain of left lower abdominal pain need to be thoroughly examined for LD.

Eosinophilic gastrointestinal disorder is uncommon and it has rarely been reported. The presence of increased numbers of eosinophils in the biopsy specimens of the gastrointestinal tract, the infiltration of eosionophils in intestinal crypts and gastric glands, the absence of involvement of other organs and the exclusion of other causes of eosinophilia support the diagnosis of eosinophilic gastroenteritis. This is characterized by infiltration of eosinophils in the gastrointestinal wall, and it's associated with protein-losing enteropathy, hypoalbuminemia, motility abnormalities and ascites. Although it is an idiopathic disorder, allergic and immunologic etiologies have been suggested. Steroid is the treatment of choice, but an operation is necessary in case of a surgical abdomen or if the patient is refractory to steroid therapy. Recently, authors experience 2 cases of eosinophilic gastroenteritis causing gastro-intestinal obstruction, and report here with clinical evaluation and literature review.

Mesenteric venous thrombosis (MVT) is uncommon, but it is often aggravated to a lethal form of intestinal ischemia. Multiple risk factors are associated with mesenteric venous thrombosis, including hypercoagulable or inflammatory states, previous abdominal surgery, abdominal trauma, portal hypertension and oral contraceptives. The use of estrogen-containing oral contraceptives accounts for 4% to 5% of all the cases of MVT. Oral contraceptives have been reported to decrease antithrombin III, increase the levels of prothrombin complex factor and factor VIII, and to inhibit the fibrinolytic system. We describe here a case of 42-year-old woman who had taken oral contraceptives for 7 years and she was diagnosed to have Protein C and Protein S deficiency, and superior mesenteric venous (SMV) and portal vein thrombosis. She underwent segmental resection of the small bowel. She was later discharged without suffering with short bowel syndrome or any other complications.

An adenomyoma of the gastrointestinal tract is a rare, benign, tumor-like condition histologically characterized by glandular structures embedded within a smooth muscle stroma. An adenomyoma has been considered to be as an abortive variant of an ectopic pancreas. An ectopic pancreas is defined as the presence of pancreatic tissue that lacks anatomic and vascular continuity with the main body of the pancreas. Common sites of an ectopic pancreas are the stomach, duodenum, and upper jejunum. An adenomyoma may rarely undergo a malignant transformation or cystic dystrophy. Recently, the authors an experienced a case of an incidental adenomyoma of the stomach associated with early gastric carcinoma. We report that case here.

A Burkitt's lymphoma is a rare disease belonging to the aggressive non-Hodgkin's lymphomas, which usually occurs in children or adolescents. Burkitt's lymphoma was first reported in the medical literature as a jaw sarcoma of East African children, and those of the gastrointestinal tract occurring in adults have rarely been reported in Korea. Herein, we report an unusual case of a primary intestinal Burkitt's lymphoma, presenting with a palpable abdominal mass and abdominal pain, in a 46-year-old man. An ileocecectomy was performed, and the diagnosis confirmed by histological examination.

We report the case of a 77-year-old woman who presented with periumbilical pain from perforation of jejunal diverticula. The patient underwent surgery and multiple jejunal diverticula were found distributed from 30 cm to 60 cm distal to the ligament of Treitz. A segment of the jejunum containing all diverticula was resected and end-to-end anastomosis was performed. The postoperative course was uneventful. The patient continued to do well at last follow-up, 26 months after operation. Diverticulum of the jejunum is uncommon and the majority of patients are asymptomatic. Symptoms indicating diverticulum are few and often nonspecific; they may present either as generalized abdominal pain associated with intestinal disturbances or in more serious case, they can lead to complications requiring emergency surgery. In light of these considerations, we thought it useful to report a case of complicated multiple jejunal diverticula and draw attention to its complications that can be a source of gastrointestinal symptoms.

A carcinoid tumor of the stomach is a neuroendocrine tumor originating from enterochromaffin cells in the submucosa of the stomach and has no specific clinical symptoms. They are uncommon, accounting for no more than 0.3% of all gastric tumors. However, this frequency has increased markedly due to endoscopic screening. Herein, the case of a 47-year-old man with a polypoid lesion (2 cm diameter) detected on endoscopic examination is reported. It was diagnosed as a carcinoid tumor before an operation. Although the tumor size was slightly larger than 2 cm in diameter, the lesion was treated by wedge resection as there was no lymph node involvement or other distant metastasis. The postoperative has course was uneventful. The patient has continued to do well for over 15 months of follow up.

BACKGROUND: Plasma cell cheilitis is an idiopathic, benign, inflammatory mucosal condition characterized by a dense plasma cell infiltrate in the mucosa. OBJECTIVE: The aim of this study was to examine the clinical & histopathologic findings of plasma cell cheilitis and review the literatures. METHODS: A total of 8 patients confirmed as plasma cell cheilitis at the Catholic University Hospital from 1999 to 2001 were retrospectively analyzed with hospital charts and histopathologic slides to determine the clinical manifestations, associated diseases, etiology, course, and prognosis and histopathologic findings. RESULTS: The results are summarized as follows; 1. The male and female ratio was 3: 1. 2. The mean age of patients was 68.5 years. 3. The site of plasma cell cheilitis was the lower lip on all patients. 4. The lesion accompanied erosion or ulcer in 75% of patients and easily bleeding in 50% of patients. 5. There was no specific symptom in 50% of patients and pain accompanied in 37.5% of patients. 6. There were good responses on topically applicated clobetasone propionate. 7. Histopathologic features revealed band-like dense infiltration of plasma cells in the upper dermis and there are no atypical nucleus and mitosis. CONCLUSION: Characteristically, plasma cell cheilitis affects the low lip of an elderly person. The histological features are diagnostic. We suggest that plasma cell cheilitis exists much more than diagnosed and that physicians must pay attention to it.

BACKGROUND: Lymphocytopenia is a common finding in critically ill patients while lymphocyte depletion in critically ill patients is presumed to have little clinical significance. However, a total lymphocyte count has been reported to provide prognostic information in surgical patients. The aim of this study was to evaluate the association of a total lymphocyte count (TLC) with a prognostic criterion in critically ill patients. METHODS: The patients were divided into three groups according to their TLC on admission to intensive care unit (ICU) (Group 1: TLC > 1.0 x 10(9)/L, Group 2: 0.7 x 10(9)/L < TLC < 1.0 x 10(9)/L, and Group 3: TLC <0.7 x 10(9)/L). Outcomes examined were patients' in-hospital mortality, length of hospital stay and incidence of infection. RESULTS: Patients with a TLC less than 0.7 x 10(9)/L (Group 3) had an infection twice (32% VS 15%) as often as those with a TLC more than 0.7 109/L (Group 1 2). But, in the hospital stay and mortality, there was no significant difference among the groups. CONCLUSIONS: TLC is very useful indicator in critically ill patients with a high risk of hospital infection on ICU admission.
