Peripheral cementifying fibroma is histomorphologically similar to the central cementifying fibroma, but this lesion is unique to the gingival mucosa and is only rarely seen in edentulous area. In most instances, it arise from interdental papilla, with 80% occurring anterior to molar region. This lesion appears to involve the maxilla and mandible equally, demonstrates the highest occurrence rate during the second decade of life, and affects female more frequently than male, with 4.3:1 to 3:2. Peripheral cementifying fibroma presents as firm, pedunculated or sessile mass with an intact or ulcerated surface depending on the presence of trauma. Microscopically, it reveals a highly cellular mass of connective tissue containing numerous plump, proliferating fibrolasts and several forms of calcification. Effective treatment requires deep excision, which includes the ligament and periosteum, followed by a thorough root scaling of the adjacent teeth. A reveiw of the literature and a report of a case of peripheral cementifying fibroma are presented.

PURPOSE: There are a number of conditions that can lead to a hypercoagulable state, however, protein C and S deficiencies are frequently described as causes of the hypercoagulable states. The aim of this study was to evaluate the clinical features and prognosis of vascular diseases associated with protein C and/or S deficiencies and to determine an adequate treatment modality for such cases. METHODS: We prospectively evaluated 7 cases with vascular disease caused by protein C and/or S deficiencies confirmed with serologic tests. RESULTS: Four patients showed venous thrombosis, 1 peripheral arterial insufficiency, 1 cerebral venous thrombosis and peripheral arterial insufficiency, and 1 portal vein thrombosis. Surgical intervention was required in 5 patients. Full anticoagulation with heparin sodium followed by warfarin sodium was done in all patients. CONCLUSION: Protein C and S deficiencies may influence clinical management. Patients presenting with atypical vascular involvement without evidence of other risk factors should be evaluated for a hypercoagulable state. Once the diagnosis is made, patients should be treated with full anticoagulation.

BACKGROUND: Because acute cholecystitis in elderly hip fracture is not easily distinguishable from other gastrointestinal symptoms and involves atypical clinical behaviors, it may not be diagnosed in the early stage. However, the exact incidences could not be reported. We utilized data from a nationwide claims database and attempted to assess the incidence of acute cholecystitis in elderly hip fracture patients and how cholecystitis affects mortality rates after hip fracture. METHODS: Study subjects were from the Korean National Health Insurance Service-Senior cohort. From a population of approximately 5.5 million Korean enrollees > 60 years of age in 2002, a total of 588,147 participants were randomly selected using 10% simple random sampling. The subjects included in this study were those who were over 65 years old and underwent surgery for hip fractures. RESULTS: A total of 15,210 patients were enrolled in the cohort as hip fracture patients. There were 7,888 cases (51.9%) of femoral neck fracture and 7,443 (48.9%) cases of hemiarthroplasty. Thirty-six patients developed acute cholecystitis within 30 days after the index date (30-day cumulative incidence, 0.24%). Four of the 36 acute cholecystitis patients (11.1%) died within 30 days versus 2.92% of patients without acute cholecystitis. In the multivariate-adjusted Poisson regression model, hip fracture patients with incident acute cholecystitis were 4.35 (adjusted risk ratio 4.35; 95% confidence interval, 1.66–11.37; P = 0.003) times more likely to die within 30 days than those without acute cholecystitis. CONCLUSION: Incidence of acute cholecystitis in elderly patients after hip fracture within 30 days after the index date was 0.24%. Acute cholecystitis in elderly hip fracture patients dramatically increases the 30-day mortality rate by 4.35-fold. Therefore, early disease detection and management are crucial for patients.

BACKGROUND: The neuromuscular blocking effects of a nondepolarizing neuromuscular blocker (NDNM) during a nitroglycerin (NTG) infusion were significantly potentiated and prolonged. NTG reduced the requirement of a NDNM in surgical patients. We investigated the influence of a NTG single bolus injection on a mivacurium nuromuscular blockade. METHODS: We studied 36 adult surgical patients, ASA physical status I or II, between 15 and 53 years old. Neuromuscular monitoring was measured by TOF-GUARD (Biometer Co., Denmark). Anesthesia was induced by thiopental sodium 3-5 mg/kg and fentanyl 3 microgram/kg, and maintained with 3 L/min N2O, 2 L/min O2 and 1 vol.% isoflurane. Patients were randomly assigned to 3 groups: 1) Control group (mivacurium 0.16 mg/kg), 2) N100 group (mivacurium 0.16 mg/kg, NTG 100 microgram), 3) N200 group (mivacurium 0.16 mg/kg, NTG 200 microgram). We measured the train-of-four (TOF) response from the beginning of recovery to the complete regaining of muscle twitch. RESULTS: NTG produced a prolongation of the neuromuscular blocking effect by mivacurium. T1 (contro group: 12.1 +/- 0.5, N100 group: 15.8 +/- 0.4 and N200 group: 11.6 +/- 0.4 min), T25 (16.4 +/- 0.4, 20.5 +/- 0.5 and 14.9 +/- 1.0 min), T75 (22.5 +/- 0.9, 29.4 +/- 0.7 and 20.1 +/- 1.0 min), T95 (27.3 +/- 0.6, 39.6 +/- 0.7 and 24.6 +/- 1.5 min) and the recovery index (6.1 +/- 0.6, 9.0 +/- 0.4 and 5.3 +/- 0.7 min) were significantly prolonged in the N100 and N200 groups (P < 0.05). CONCLUSION: These results suggest that a NTG bolus injection prolonged the neuromuscular blocking effect of mivacurium, dose relatively.

Cutaneous endometriosis seems to be more common in women who have had a pelvic or abdominal operation and primary cutaneous endometriosis is very rare. In our hospital we experienced a 41-year-old woman who complained of the appearance at the umbilicus of a nodule and had not had operation. This nodule was responsible for recurrent pain and increasing in size and it was excised. Pathology findings revealed cutaneous endometriosis. So we present a case of primary cutaneous endometriosis with a brief review of literature.

Superior mesenteric artery (SMA) syndrome is a rare disorder, characterized by compression of the third segment of the duodenum by the mesenteric artery at the level of the SMA, resulting in duodenal dilatation. The most characteristic symptoms are postprandial epigastric pain, fullness, voluminous vomiting, and eructation. The diagnosis may be difficult, but can be confirmed by upper gastrointestinal (UGI) contrast studies. We report a case of SMA syndrome in a 66-year-old patient with hematemesis. Endoscopy showed deep circular ulcerations with bleeding in the distal esophagus. Computed tomography (CT) and an UGI contrast series revealed distension of the stomach and duodenum, with a cut-off in the third portion of the duodenum. We treated the patient conservatively, but the patient's symptoms did not improve. Ultimately, the patient underwent successful gastrojejunostomy with a favorable postoperative outcome.

BACKGROUND/AIMS: Diabetes mellitus (DM) is associated with an increased incidence of colon cancer. However, the relationship between DM and colorectal adenoma is not definite. In this study, we sought to determine the association between DM and the prevalence of colorectal adenoma. METHODS: We enrolled 606 patients with DM and 606 asymptomatic adults who underwent colonoscopy for routine health evaluations from June 2003 to June 2007. The frequency and characteristics of the colorectal adenomas were analyzed and compared between the two groups. RESULTS: The sex ratio and mean age were 1.67:1 (M:F) and 58.1+/-10.6 years, respectively, in patients with DM, and 1.68:1 and 57.6+/-8.9 years, respectively, in patients without DM, and these values were similar. The frequency of colorectal adenoma was 33.2% for the patients with DM and 32.3% for the patients without DM. The frequency, location, number, size and histopathologic findings of the colorectal adenomas were not different between the two groups. Among the patients with DM, the frequency of colorectal adenoma was 35.7% in the patients treated with oral hypoglycemic agents and 31.4% in the patients treated with insulin. Also, the other characteristics of the colorectal adenomas were not different according to the treatment method. CONCLUSIONS: The frequency and characteristics of colorectal adenomas were not different between the patients with and without DM.
