Background/Aims:
This study aimed to investigate whether everolimus (EVR) affects long-term survival after liver transplantation (LT) in patients with hepatocellular carcinoma (HCC).
Methods:
The data from 303 consecutive patients with HCC who had undergone LT from January 2012 to July 2018 were retrospectively reviewed. The patients were divided into two groups: 1) patients treated with EVR in combination with calcineurin inhibitors (CNIs) (EVR group; n=114) and 2) patients treated with CNI-based therapy without EVR (non-EVR group; n=189). Time to recurrence (TTR) and overall survival (OS) after propensity score (PS) matching were compared between the groups, and prognostic factors for TTR and OS were evaluated.
Results:
The EVR group exhibited more aggressive tumor biology than the non-EVR group, such as a higher number of tumors (P=0.003), a higher prevalence of microscopic vascular invasion (P=0.017) and exceeding Milan criteria (P=0.029). Compared with the PS-matched non-EVR group, the PS-matched EVR group had significantly better TTR (P<0.001) and OS (P<0.001). In multivariable analysis, EVR was identified as an independent prognostic factor for TTR (hazard ratio [HR], 0.248; P=0.001) and OS (HR, 0.145; P<0.001).
Conclusions
Combined with CNIs, EVR has the potential to prolong long-term survival in patients undergoing LT for HCC. These findings warrant further investigation in a well-designed prospective study.

Cushing's syndrome is characterized by excessive cortisol and immuno-suppression.We experienced a case of Cushing's syndrome caused by adrenocortical carcinoma that was complicated by multiple opportunistic infections. A 37-year-old woman with adrenocortical carcinoma (ACC) presented with decreased mental ability and high fever one week after undergoing chemotherapy. Her initial blood culture revealed methicillinresistant Staphylococcus aureus (MRSA) bacteremia accompanied by septic pneumonia. We admitted her to the intensive care unit and treated her for invasive pulmonary aspergillosis (IPA), Pneumocystis jirovecii pneumonia (PJP), candidemia, and Stenotrophomonas maltophilia pneumonia with broad-spectrum antibiotics and antifungal agents. Nevertheless, her clinical course worsened and she died. Herein, we report a case of Cushing's syndrome associated with cortisol-secreting ACC that presented with multiple opportunistic infections, including MRSA bacteremia, septic pneumonia, candidemia, PJP, and IPA, illuminating a relationship between hypercortisolemia and opportunistic infections.

BACKGROUND: Prophylaxis for hepatitis B virus (HBV) recurrence is essential after liver transplantation (LT) in HBV-associated recipients. We conducted real-world analysis of HBV prophylaxis after LT in the Korean population.METHODS: Korean Organ Transplantation Registry (KOTRY) database and additionally collected data (n = 326) were analyzed with special reference to types of HBV prophylaxis.RESULTS: The study cohort comprised 267 cases of living-donor LT and 59 cases of deceased-donor LT. Hepatocellular carcinoma (HCC) was diagnosed in 232 (71.2%) of these subjects. Antiviral agents were used in 255 patients (78.2%) prior to LT. HBV DNA was undetectable in 69 cases (21.2%) and detectable over wide concentrations in the other 257 patients (78.8%) prior to LT. Polymerase chain reaction analysis of the store blood samples detected HBV DNA in all patients, with 159 patients (48.9%) showing concentrations > 100 IU/mL. Post-transplant HBV regimens during the first year included combination therapy in 196 (60.1%), hepatitis B immunoglobulin (HBIG) monotherapy in 121 (37.1%), and antiviral monotherapy in 9 (2.8%). In the second post-transplant year, these regimens had changed to combination therapy in 187 (57.4%), HBIG monotherapy in 112 (34.4%), and antiviral monotherapy in 27 (8.3%). Trough antibody to hepatitis B surface antigen titers > 500 IU/mL and >1,000 IU/mL were observed in 61.7% and 25.2%, respectively. The mean simulative half-life of HBIG was 21.6 ± 4.3 days with a median 17.7 days. Up to 2-year follow-up period, HCC recurrence and HBV recurrence developed in 18 (5.5%) and 6 (1.8%), respectively. HCC recurrence developed in 3 of 6 patients with HBV recurrence.CONCLUSION: Combination therapy is the mainstay of HBV prophylaxis protocols in a majority of Korean LT centers, but HBIG was often administered excessively. Individualized optimization of HBIG treatments using SHL is necessary to adjust the HBIG infusion interval.

Osteoma is a slow-growing benign tumor that consists of mature or cancellous bone. It most commonly occurs in the frontoethmoidal area of the paranasal sinus and is usually asymptomatic. Surgical excision is necessary for osteoma, which causes symptoms such as headache, nasal obstruction, facial asymmetry, and visual disturbance. Surgical approaches should also be considered depending on the size and location of the osteoma, in order to reduce intracranial and orbital complications. We recently treated a huge frontoethmoid osteoma involving the skull base and orbit, which was removed via endoscopic sinus surgery and a combined extracranial approach. Herein, we report this case with a review of the relevant literature.

BACKGROUND: We purposed to systemically review studies investigating the prophylactic effect of both pharmacological and non-pharmacological modalities against rocuronium induced withdrawal movement (RIWM) in the Korean population. METHODS: Literature search was performed using MEDLINE, EMBASE, CENTRAL, Koreamed, KMBASE, KISS and RISS up to March 2014. Randomized controlled trials (RCTs) comparing pharmacological and non-pharmacological interventions with placebo aimed for the Korean population were included. Outcome measures were the incidence and severity of RIWM. We conducted subgroup analyses according to each intervention method. RESULTS: Data were analyzed from 41 RCTs totaling 4,742 subjects. The overall incidence of RIWM was about 80% (range 56-100%). Incidence and severity of RIWM were significantly reduced with lidocaine (risk ratio [RR] 0.60, 95% CI 0.49-0.74; standardized mean difference [SMD] -0.74, 95% CI -1.05 to -0.44), opioids (RR 0.28, 95% CI 0.18-0.44; SMD -1.71, 95% CI -2.09 to -1.34) and hypnotics (RR 0.36, 95% CI 0.25-0.52; SMD -2.20, 95% CI -2.62 to -1.79). Regardless of tourniquet use, lidocaine showed a prophylactic effect against incidence and severity of RIWM: tourniquet (RR 0.36, 95% CI 0.21-0.62; SMD -1.51, 95% CI -2.15 to -0.86); non-tourniquet (RR 0.58, 95% CI 0.47-0.71; SMD -0.74, 95% CI -1.05 to -0.44). Dilution and slow injection of rocuronium decreased incidence and severity of RIWM: dilution (RR 0.47, 95% CI 0.39-0.56; SMD -1.64, 95% CI -2.47 to -0.81); slow injection (RR 0.34, 95% CI 0.17-0.70; SMD -2.13, 95% CI -2.74 to -1.51). CONCLUSIONS: The greater part of pharmacological and non-pharmacological interventions showed prophylactic effect against the incidence and severity of RIWM in the Korean population.

BACKGROUND AND OBJECTIVES: Because of the wide application of the endoscopic diagnostic system and increased amount of attention for early stage congenital cholesteatoma (CC) recently, the detection of CC in stages I and II has increased. In this study, we investigated the effectiveness of minimally invasive transcanal myringotomy (MITM), and compared its results with those of postauricular approach (PAA) in early stage CC consisting of stage I and II of Potsic's classification. SUBJECTS AND METHOD: We retrospectively studied 70 patients who were diagnosed with CC after surgery performed by an otologist from June 2006 to June 2013. Thirty-two patients were in early stage CC consisting stage I and II. Of the 32 patients, MITM was performed on 20 and PAA was performed on 12. We analyzed the characteristics of disease, operation time, hospitalization period, recurrence and complications according to the stage and each operation. RESULTS: There were no significant differences between the stages and types of the disease between the MITM and the PAA group (p>0.05). The operation time and hospitalization period for the MITM group were significantly shorter than for the PAA group (p<0.001). There was no recurrence in the two groups during the average follow-up period of 33 months follow-up. Tympanic membrane perforation occurred in one patient in the MITM group. One patient presenting an external aural epidermal cyst in the PAA group was treated with surgical removal. CONCLUSION: The MITM is an efficacious and feasible method to remove early stage CC.

A twenty-year-old male visited our clinic with wrist and long finger metacarpophalangeal (MP) joint pain. Dynamic ultrasonography revealed sagittal band (SB) ulnar subluxation and extensor carpi ulnaris (ECU) volar subluxation. Magnetic resonance imaging showed longitudinal splitting and dislocation of the volar half slip of the ECU tendon. The redundant radial SB was augmented and ECU sheath was advanced to the periosteum using suture anchors. He was able to perform his previous activities at the last follow-up. We encountered a case of "simulateous" ECU dislocation with extensor tendon subluxation of the long finger at the MP joint. Therefore, we report this case with a review of the relevant literature.

PURPOSE: Dispatcher-assisted telephone instruction during cardiopulmonary resuscitation (CPR) improves the quality of CPR performed by laypersons. However, in Korea, CPR instruction guidelines for bystanders have not made. We therefore studied the effects of verbal instruction on the quality of chest compression. METHODS: Data from two randomized, double-blinded, controlled trials using identical methodology were combined to obtain 175 records for analysis. Subjects were randomized into either a "push as hard as you can and fast" (n=87) or "push down 5~6 cm, 100~120 rate/min" (n=88), verbal instructions in the 2011 Korea Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC). Data were recorded via a Resusci(R) Anne SkillReporter(TM), Laerdal Medical mannequin. Primary outcome measures included chest compression depth and chest compression rate per minute. RESULTS: The average compression depth and speed of chest compressions did not significantly differ between the two verbal instructions. CONCLUSION: The verbal istructions provided by telephone based on the 2011 Korean Guidelines for CPR and ECC are not effective. The instructions for high quality CPR of layperson should therefore be studied.
