The cut-off value of transient elastography to the value of hepatic venous pressure gradient in alcoholic cirrhosis

Background/Aims@#The hepatic venous pressure gradient (HVPG) reflects portal hypertension, but its measurement is invasive. Transient elastography (TE) is a noninvasive method for evaluating liver stiffness (LS). We investigated the correlation between the value of LS, LS to platelet ratio (LPR), LS-spleen diameter-to-platelet ratio score (LSPS) and HVPG according to the etiology of cirrhosis, especially focused on alcoholic cirrhosis. @*Methods@#Between January 2008 and March 2017, 556 patients who underwent HVPG and TE were consecutively enrolled. We evaluated LS, LPR, and LSPS according to the etiology of cirrhosis and analyzed their correlations with HVPG. @*Results@#The LS value was higher in patients with alcoholic cirrhosis than viral cirrhosis based on the HVPG (43.5 vs. 32.0 kPa, P<0.001). There were no significant differences in the LPR or LSPS between alcoholic and viral cirrhosis groups, and the areas under the curves for the LPR and LSPS in subgroups according to HVPG levels were not superior to that for LS. In alcoholic cirrhosis, the LS cutoff value for predicting an HVPG ≥10 mmHg was 32.2 kPa with positive predictive value (PPV) of 94.5% and 36.6 kPa for HVPG ≥12 mmHg with PPV of 91.0%. @*Conclusions@#The LS cutoff value should be determined separately for patients with alcoholic and viral cirrhosis. In alcoholic cirrhosis, the LS cutoff values were 32.2 and 36.6 kPa for predicting an HVPG ≥10 and ≥12 mmHg, respectively. However, there were no significant differences in the LPR or LSPS between alcoholic and viral cirrhosis groups.

Maxillary implant-supported fixed prosthesis engaged by distal-extension removable partial denture for 10 years: a case report

Prosthodontic decision and management should be considered the patient’s aesthetic need for anterior teeth in maxillary edentulism. This case report describes 10-year clinical outcome of a maxillary edentulous patient was rehabilitated by means of an implant-supported fixed dental prosthesis (ISFDP) for the anterior region and a distal-extension removable partial denture (RPD) for the posterior region. The ISFDP was designed to splint 4 endosseous implants as one unit and engaged by the RPD. The edentulous mandible was restored by means of an implant-supported overdenture. Over the course, no major adverse event occurred other than wear, discoloration, and breakage of resin veneers and artificial teeth.

A case of cardiac arrest following bupivacaine injection for shoulder arthroscopy : A case report

Intra-articular administration of local anesthetics such as bupivacaine can produce short-term postoperative analgesia in patients who are undergoing shoulder arthroscopy. Yet bupivacaine can result in cardiovascular toxicity that can lead to cardiac arrest. We experienced a case of 63-year-old male patient with severe cardiac toxicity that led to ventricular fibrillation 15 minutes after injecting 0.5% bupivacaine into the patient's shoulder joint for shoulder arthroscopy.

Multiple Metastatic Brain Tumor: Complicated with Post-dural Puncture Headache : A case report

Epidural blood patch is an effective management for treatment of severe post-dural puncture headache. Here we describe a case of a patient with hip fracture, who was complained regarded as having suspicious post-dural puncture headache after epidural anesthesia, but it failed to be treated with 4 times of epidural blood patch, and later was diagnosed with multiple metastatic brain tumor.

The Preventive Effects of Dexamethasone and Ondansetron for Postoperative Nausea and Vomiting after Tympanomastoidectomy / 대한마취과학회지

BACKGROUND: Postoperative nausea and vomiting (PONV) is the major cause of patient's discomfort after surgery. Dexamethasone and ondansetron have been known to have some preventive effects on PONV. The purpose of this study was to compare the effects combination therapy of these drugs in the prevention of PONV after tympanomastoidectomy which has been known to be a high risk factor of PONV. METHODS: Ninty patients scheduled tympanomastoidectomy under general anesthesia were included. Patients were randomly divided into three groups and received dexamethasone 5 mg (group D), ondansetron 4 mg (group O), or dexamethasone 5 mg plus ondansetron 4 mg (group DO) at 30 min before the end of operation. The degree of PONV was assessed at 6 h, 12 h, 24 h, and 48 h after operation. RESULTS: The degrees of nausea in group DO during 0-6 h and 6-12 h were lesser than those of other groups. The overall incidences of nausea were 73% (group D), 62% (group O), and 23% (group DO, P < 0.05). The degrees of vomiting in group O and DO during 0-6 h were lesser than those of group D. The overall incidences of vomiting were 37% (group D), 17% (group O), and 7% (group DO, P < 0.05). CONCLUSIONS: The combination of dexamethasone and ondansetron is more effective than single use of each drug for the prevention on PONV after tympanomastoidectomy.
