1.Diagnosis and Management of Esophageal and Gastric Variceal Bleeding: Focused on 2019 KASL Clinical Practice Guidelines for Liver Cirrhosis
The Korean Journal of Gastroenterology 2021;78(3):152-160
Varices are a frequent complication of liver cirrhosis and a major cause of mortality in patients with liver cirrhosis. Patients with decompensated cirrhosis complications have a poor prognosis and require careful management. Portal hypertension is the most common complication of liver cirrhosis, which is the key determinant for varices development. Increased intrahepatic vascular resistance to portal flow leads to the development of portal hypertension. Collateral vessels develop at the communication site between the systemic and portal circulation with the progression of portal hypertension. Varices are the representative collaterals, develop gradually with the progression of portal hypertension and may eventually rupture. Variceal bleeding is a major consequence of portal hypertension and causes the death of cirrhotic patients. The present paper reviews the latest knowledge regarding the diagnosis and management of esophageal and gastric variceal bleeding.

The estrogen receptor (ER) is present in a wide variety of mammalian tissues and is required for the physiological responses of estrogen, including estrogen-induced tissue-specific changes in gene expression. But most of our knowledge on the regulation of ER mRNA levels comes from in vivo steroid replacement experiments or cancer cell lines that express the ER. Thus the present study was attempted to determine 1) the anterior pituitary ER mRNA levels during rat estrous cycle 2) if estradiol itself directly modulates the ER mRNA levels in cultured rat anterior pituitary using RT-PCR method. In rats with 4 day estrous cycle, the ER mRNA levels in anterior pituitary gland reached to maximum at proestrus 11:00h just before serum estradiol concentration showed the highest. From then, the ER mRNA levels gradually declined during the rest of the proestrus. On the other hands, in cultured rat anterior pituitary cells, the ER mRNA levels were significantly decreased by the treatment of estradiol. These results indicate that the surge of estradiol was proceeded by the increase in pituitary ER mRNA levels during the proestrus and in cultured anterior pituitary cells, estrogen might be involved in the down-regulation of the ER mRNA levels.

BACKGROUND: FSH is a heterodimeric glycoprotein and is composed of alpha and beta subunits. alpha subunit is common to FSH and LH, while an unique beta subunit determines the biological specificity of each hormone. The synthesis of beta subunit is the primary rate-limiting step in the synthesis of each hormone. Although FSH plays a pivotal role in folliculogenesis and ovulation, very little studies have been performed on the regulation of FSH beta gene expression. Therefore, the present study attempted to examine the effect of GnRH or activin on the expression of FSH beta mRNA as well as FSH release and signaling pathway involved in their actions. METHODS: The primary cultures of rat anterior pituitary were used for this study. To determine FSH beta mRNA levels, northern blotting method was used. The concentration of FSH in the culture medium was evaluated by using a specific radioimmunoassay for rat FSH. RESULTS: PMA, an activator of PKC, increased FSH beta mRNA levels and FSH release, whereas forskolin, an activator of adenylate cyclase, showed no effect. The application of GnRH augmented FSH release, but not FSH beta mRNA levels. However, the administration of activin increased FSH beta mRNA levels as well as FSH release. Staurosporine, an inhibitor of PKC, suppressed activin-induced increment of FSH beta mRNA levels and FSH release. CONCLUSION: The present study demonstrated that activin rather than GnRH is a major regulator for FSH beta mRNA expression, and suggest that PKC-dependent pathway is also involved in the action of activin on the expression of FSH beta mRNA and FSH release.

PURPOSE: A retrospective study was performed to find any indicator to predict the difficulty of percutaneous transhepatic biliary drainage(PTBD) before the procedure and to evaluate correlationship between the chronological change of fluoroscopic time and the operator's experience. MATERIALS AND METHODS: The materials included the consecutive 138 cases of PTBD of 120 patients with obstructive jaundice. Under the presumption that the difficulty of procedure would be reflected on fluoroscopic time, the correlation between fluoroscopic time and eight factors(i. e. ;sex, age, disease, approach, degree of IHD dilatation, total bilirubin, alkaline phosphatase, and operator) were analysed. Also chronological change of fluoroscopic time in three operators, who performed more than 25 procedures, were evaluated. RESULTS: Statistically significant factors were operator (P=0.000), sex (P:0.028), approach(P=0.048), and total billrubin (P=0.021). Good correlation between the chronological change of fluoroscopic time and the operator's experience was found. CONCLUSION: The significant factors could be used as an indicator to predict the difficulty before PTBD procedure. The chronological change of fluoroscopic time could be used as an indirect estimate in the stabilization of the operator fechnigue.

Ectomesenchymal chondromyxoid tumor (ECMT) is a rare tumor, exclusively arising in the anterior tongue. Thirty-eight cases have been reported in the English literature. It usually presents as a sessile protrusion and shows round to spindle cells embedded in myxoid to chondroid stroma. Tumor cells are almost always positive for polyclonal glial fibrillary acidic protein (GFAP). We report our experience in the recent treatment of a case of ECMT, the third case in 3 years. The mass in the anterior tongue revealed characteristic morphologic features of ECMT and the expression of polyclonal GFAP. Although ECMT should be differentiated from other mesenchymal tumors including myoepithelioma, its clinical, morphological, and immunohistochemical features enable its diagnosis, especially when pathologists are aware of it.

OBJECTIVE: The authors investigated the current practice of intensive psychotherapy by residents in the department of psychiatry. METHODS: We mailed a questionnaire to 126 fourth-year psychiatry residents in order to obtain data on their clients' sociodemographic characteristics, the settings in which psychotherapy is being conducted, the effects of psychotherapy, the difficulties associated with psychotherapy, the state of supervision and the level of clients' satisfaction. RESULTS: Approximately 51.5% of the residents completed the questionnaires. The average number of clients was 4.9+/-3.8, the average number of psychotherapy sessions was 26.2+/-20.1, and 69.4% of the residents had performed insight-oriented psychotherapy. Approximately 69.8% of the fourth-year residents had received some form of supervision, and 58.7% agreed to increase the frequency of supervision. Approximately 74.2% of the cases were supervised. The average number of supervisions per case was 9.2+/-10.5. CONCLUSION: The setting in which psychotherapy is conducted, number of clients, and type of supervision varied greatly among the training institutes surveyed. Based on these findings, we expect to create better psychotherapy training programs for psychiatric residents.

BACKGROUND: The zygoma is a major portion of the midfacial contour. When deformity occurs in this area, a reduction should be conducted to correct it. If a sagittal fracture at the temporal root of the zygomatic arch occurs, this also requires reduction, but it is difficult to approach due to its anatomical location, and the possibility of fixation is also limited. Thus, the authors attempted the reduction of sagittal fracture by two- or three-point fixation and the Gillies approach without direct manipulation. The preoperative and postoperative results of the patients were evaluated. Follow-up was performed to establish a treatment guideline. METHODS: A retrospective study was done with 40 patients who had sagittal fractures at the temporal root of the zygomatic arch from March 2009 to June 2012. Only two- or three-point fixation was performed for the accompanying zygomatic-orbital-maxillary fracture. The Gillies approach was used for complex fractures of the zygomatic arch, while the temporal root of the zygomatic arch was only observed without reduction. Preoperative and postoperative computed tomography and X-ray scans were performed to examine the results. RESULTS: The result of the paired t-test on preoperative and postoperative bone gap differences, the depression level, and the degree of temporal protrusion showed a marked decrease in the mean difference at a 95% confidence interval. The results were acceptable. CONCLUSIONS: In the treatment of sagittal fractures at the temporal root of the zygomatic arch, it is acceptable to use indirect reduction and non-fixation methods. This leads to a satisfactory aesthetic and functional outcome.
