Black hairy tongue is the name given to the appearance of an abnormal coating of the tongue and occurs in adults. It is the result of hyperkeratosis of the filiform lingual papillae which, on gross examination appear hair-like with a variable tinctorial aspect from yellow-brown to black. The pathogenesis is unknown. A number of etiologic factors have been implicated including the administration of topical or systemic antibiotics, poor hygiene, smoking, alcohol and the use of mouthwashes. We report a case of black hairy tongue that may be associated with oral administration of minocycline.

BACKGROUND AND PURPOSE: Primary involvement of the peripheral nerves in myotonic dystrophy type I (MyD1) is controversial. We investigated whether the involvement of peripheral nerves is a primary event of MyD1 or secondary to another complication such as diabetes mellitus (DM). METHODS: The subjects comprised 12 patients with MyD1, 12 with DM and no peripheral nerve involvement, and 25 healthy volunteers. We measured multiple excitability indices in the median motor axons. The strength-duration time constant was calculated from the duration-charge curve, the threshold electrotonus and current-threshold relationships were calculated from the sequential subthreshold current, and the recovery cycle was derived from double suprathreshold stimulation. RESULTS: The depolarizing and hyperpolarizing threshold electrotonus were significantly reduced and exhibited increased refractoriness in the MyD1 group compared with the DM and control groups. The SDTC, superexcitability, and subexcitability were not significantly altered in the MyD1 group. CONCLUSIONS: The MyD1 group exhibited a depolarized axonal membrane potential. The significant differences in peripheral nerve excitability between the MyD1 group and the DM and normal control groups suggest that peripheral neuropathy is a primary event in MyD1 rather than a secondary complication of DM.

PURPOSE: MMPs are involved in the degradation of the extracellular matrix, which is an important step in tumor invasion and metastasis. Among the MMPs, a positive correlation between the expressions of MMP-2 and MMP-9, and the aggressive behavior of breast carcinomas has been reported, but the role of the MMP-2 and MMP-9 expressions in DCIS is still not known. Angiogenesis has a crucial role in tumor growth and metastasis. The aim of this study was to investigate the relationships between the expressions of the MMPs, the angiogenic factor (VEGF) and the microvessel density (MVD) in a ductal carcinoma in situ (DCIS) of the breast. METHODS: 42 cases of DCIS, diagnosed at the Busan Paik Hospital, between 1992 and 2002, were the subjects of this study. The rates of MMP-2 and 9 expressions and VEGF were evaluated using immunohistochemistry, and the MVD was measured by CD 34 immunohistochemical staining. The statistical analyses between the expressions of MMP-2, MMP-9 and VEGF and the MVD, patient's age (more than 50 years old, less than 50 years old), histological subtype (comedo or non-comedo) and nuclear grade (I, II, III), and their correlation were exained. RESULTS: The expressions of MMP-2 and MMP-9 were noted in 20 (47.6%) and 22 (52.4%) of the 42 cases, respectively. There were no significant relationships between the expressions of MMP-2 and MMP-9 and the patient's age and histological subtype, but the expression rate of MMP-9 showed an increased tendency in cases with nuclear grades II and III compared with the cases with nuclear grade I (P=0.0863), but no significant difference between the MMP-2 expression and the nuclear grades was noted. The VEGF was expressed in 47.6% of the cases, and the mean MVD was 21 per x200 field, with 13 (30.9%) of the 42 cases showing increased MVD. The VEGF expression rate showed an increasing tendency in the cases younger than 50 years old (P= 0.1011), but no significant differences according to the histological subtype and nuclear grades were seen. There were no relationships between the MVD and the clinico-pathological factors. The MVD showed an increasing tendency in cases with a non-comedo histological type compared to the comedo type (P=0.0536). No positive correlation between the expression of VEGF and MVD was noted. No significant relationship between expressions of MMP-2 and VEGF and the MVD were seen, but the rate of MMP-9 expression was significantly higher in the VEGFpositive cases (P=0.0293), however, no relationship between MMP9 expression and MVD was found. CONCLUSION: The expressions of MMP-2 and MMP-9 in DCIS are suggestive of their involvement in the development of breast cancers. However, with non-invasive lesions, and the positive correlation between the MMP-9 and VEGF expressions and the nuclear grades, means that the expression of MMP-9 may represent the biological behavior of DCIS, but the role of MMP-2 expression is still uncertain in the development of breast carcinomas.

Advanced gastric cancer with skeletal muscle metastasis is a rare occurrence. Here, we report a rare case of gastric carcinoma with psoas muscle metastasis. This patient had advanced gastric carcinoma and complained of inability to extend the left hip joint due to pain. Because magnetic resonance imaging (MRI) revealed an iliopsoas mass showing heterogeneous signal intensity with fluid collection and enhancement around the mass, we speculated that the mass was an intramuscular metastatic tumor from primary gastric carcinoma as well as an intramuscular abscess. Histopathologically, the patient had a metastasis from primary gastric adenocarcinoma. Therefore, the patient was treated with radiotherapy and subsequent chemotherapy.

Accessory spleen can be mistaken as a gastric subepithelial mass, and may not be differentiated in CT or endoscopic ultrasonography (EUS). A gastric subepithelial mass was detected on routine endoscopy in a 39-year old woman with history of splenectomy. In subsequent CT and EUS, the subepithelial mass was located on the fourth layer of the stomach. To make a definite diagnosis, EUS-guided fine needle aspiration (FNA) was performed, and a splenic tissue was demonstrated in histologic examination. EUS-guided FNA can be beneficial in the diagnosis of accessory spleen which mimics a gastric subepithelial mass.

Background/Aims: We developed a new endoscopic submucosal dissection (ESD) simulator and evaluated its efficacy and realism for use training endoscopists. Methods: An ESD simulator was constructed using polyvinyl alcohol hydrogel sheets and compared to a previous ESD simulator. Between March 1, 2020, and December 30, 2021, eight expert endoscopists from three different centers analyzed the procedure-related factors of the simulator. Five trainees performed gastric ESD exercises under the guidance of these experts. Results: Although the two ESD simulators provided overall favorable outcomes in terms of ESD-related factors, the new simulator had several benefits, including better marking of the target lesion’s limits (p<0.001) and overall handling (p<0.001). Trainees tested the usefulness of the new ESD simulator. The complete resection rate improved after 3 ESD training sessions (9 procedures), and the perforation rate decreased after 4 sessions (12 procedures). Conclusions We have developed a new ESD simulator that can help beginners achieve a high level of technical experience before performing real-time ESD procedures in patients.

OBJECTIVES: The purpose of the current study was to evaluate the usefulness of the following four comorbidity indices in gastric cancer patients who underwent surgery: Charlson Comorbidity Index (CCI), Cumulative Illness rating scale (CIRS), Index of Co-existent Disease (ICED), and Kaplan-Feinstein Scale (KFS). METHODS: The study subjects were 614 adults who underwent surgery for gastric cancer at K hospital between 2005 and 2007. We examined the test-retest and inter-rater reliability of 4 comorbidity indices for 50 patients. Reliability was evaluated with Spearman rho coefficients for CCI and CIRS, while Kappa values were used for the ICED and KFS indices. Logistic regression was used to determine how these comorbidity indices affected unplanned readmission and death. Multiple regression was used for determining if the comorbidity indices affected length of stay and hospital costs. RESULTS: The test-retest reliability of CCI and CIRS was substantial (Spearman rho=0.746 and 0.775, respectively), while for ICED and KFS was moderate (Kappa=0.476 and 0.504, respectively). The inter-rater reliability of the CCI, CIRS, and ICED was moderate (Spearman rho=0.580 and 0.668, and Kappa=0.433, respectively), but for KFS was fair (Kappa=0.383). According to the results from logistic regression, unplanned readmissions and deaths were not significantly different between the comorbidity index scores. But, according to the results from multiple linear regression, the CIRS group showed a significantly increased length of hospital stay (p<0.01). Additionally, CCI showed a significant association with increased hospital costs (p<0.01). CONCLUSIONS: This study suggests that the CCI index may be useful in the estimation of comorbidities associated with hospital costs, while the CIRS index may be useful where estimatation of comorbiditie associated with the length of hospital stay are concerned.

Duodenal abscess is a rarely reported disease throughout the entire world. Duodenal abscesses are developed mostly from the complication of duodenal ulcer perforation, and only small percentage of duodenal abscesses are the result of cholecysto-duodenal fistula which was made by gall bladder perforation. We report a 84-year-old male patient who presented to the emergency department with severe anorexia and generalized weakness for 2 weeks. The upper gastrointestinal endoscopy done and revealed a protruding mass at the lesser curvature of the duodenal bulb. As soon as the mass was punched with a biopsy forceps, a large amount of abscess began to pour out into the intestinal lumen. Abdominal CT scan demonstrated the presence of an air-fluid level the in gall bladder and also abscess in the porta hepatitis which was located between the gall bladder and the duodenum. Because the patient refused any surgical intervention, we treated him conservatively with intravenous antibiotics. Patient's symptom of anorexia was slowly resolved, and patient was discharged 10 days later.
