A 12-year-old girl with hypertension, hypokalemia, cystic ovaries and absence of secondary sexual development is presented. Hormonal study revealed very low levels of cortisol, testosterone, estrogen, and high levels of progesterone, deoxycorticosterone, corticosterone, FSH and ACTH. Following treatment with dexamethasone and estrogen, the levels of the latter group remarkably decreased. Serum potassium level and blood pressure also became normal. With all the above hormonal profile and clinical findings, we reached the diagnosis of 17alpha-hydroxylase deficiency and report this case with the review of literature.

PURPOSE: Dexamethasone intramuscular injection and oral prednisolone have been known to be effective in the treatment of croup. The aim of this study was to determine whether nebulized budesonide leads to clinically important improvement in respiratory symptoms within four hours for child with mild to moderate croup. METHODS: Patients with croup visited to the department of Pediatrics, Han Il General Hospital from March 1995 to June 1996 were enrolled in this study. Patients were eligible if their age was between six months and six years, their total croup score was higher than 2 after breathing humidified air for at least 15 minutes. 28 patients were treated with 2mg (8ml) of nebulized budesonide and 8 patients with 8ml of normal saline as control group over the 30 minutes. Croup score, heart rate and respiratory rate were then assessed hourly for up to four hours. Side effects were also observed. RESULTS: 1) The croup score was improved from 3.6+/-0.8 to 1.9+/-0.9 at 4 hours after the nebulized budesonide treatment. 2) No significant differences in changes in heart rate were observed until 4 hours after both the nebulized budesonide group and control group. 3) Significant decrease in respiratory rate was observed at 4 hours after the nebulized budesonide group. 4) No specific side effects were noted during and 4 hours after the nebulized budesonide treatment. CONCLUSIONS: We concluded that nebulized budesonide leads to a prompt and important clinical improvement in children with mild to moderate croup without any specific side effects.

Amebiasis is an infectious disease caused by Entameba histolytica. Amebiasis remains an extremely important consideration in the differential diagnosis of diarrhea, especially when there is associated bleeding. It is imperative that appropriate studies to establish or exclude the diagnosis of amebiasis be carried out in all patients who present with a clinical and sigmoidoscopic picture of colitis, and that patients treated with metronidazole for amebiasis have adequate clinical and parasitological follow-up. We have experienced one case of intestinal amebiasis with protein losing enteropathy in 30month-old boy whose chief complaint was mild fever, vomiting and blood tinged diarrhea. His laboratory findings were compatible with protein losing enteropathy. The diagnosis of amebiasis is confirmed by observation of trophozoite of E. histolytica in the stools. A brief review with related literatures is also presented.

PURPOSE: To determine whether initial corrected anion gap (C(o)AG), base excess caused by unmeasured anions (BEua), and strong ion gap (SIG) can predict the morbidity of critically ill patients admitted to emergency department (ED). METHODS: 138 patients who visited the critical section of the ED and were admitted to intensive care unit (ICU) were enrolled. We calculated the C(o)AG, BEua, and SIG from the initial blood samples of the patients and initial logistic organ dysfunction score (LODS) also. Then we measured the LODS at the last day of ICU stay again. Comparing with the initial LODS, we divided the patients into two groups based on the changes of the values: favorable group and poor group. RESULTS: There was a significant difference in the mean AGcorr (p=0.007), BEua (p=0.008), SIG (p=0.037) between favorable and poor group. The area under the receiver operating characteristic (AUROC) curves for morbidity prediction were relatively small: 0.66 (95% CI, 0.56-0.77) for C(o)AG, 0.65 (95% CI, 0.54-0.76) for BEua, and 0.59 (95% CI, 0.49-0.70) for SIG. CONCLUSION: We found the initial unmeasured anions at the ED of the patients who eventually showed improved LODS during ICU period are significantly different to those of the other patients. But they failed to show enough capability of discriminating the morbidities between two groups.

Background:
Various regional analgesia techniques are used to reduce postoperative pain in patients undergoing video-assisted thoracic surgery (VATS). This study aimed to determine the relative efficacy of regional analgesic interventions for VATS using a network meta-analysis (NMA).
Methods:
We searched the Medline, EMBASE, Cochrane Controlled Trial Register, Web of Science, and Google Scholar databases to identify all randomized controlled trials (RCTs) that compared the analgesic effects of the following interventions: control, thoracic paravertebral block (TPVB), erector spinae plane block (ESPB), serratus plane block (SPB), and intercostal nerve block (INB). The primary outcome was opioid consumption during the first 24-h postoperative period. Pain scores were also collected during three different postoperative periods: the early (0–6 h), middle (6–18 h), and late (18–24 h) periods.
Results:
A total of 21 RCTs (1391 patients) were included. TPVB showed the greatest effect on opioid consumption compared with the control (mean difference [MD] = −13.2 mg; 95% CI [−16.2, −10.1]). In terms of pain scores in the early period, ESPB had the greatest effect compared to control (MD = −1.6; 95% CI [−2.3, −0.9]). In the middle and late periods, pain scores showed that TPVB, ESPB and INB had superior analgesic effects compared to controls, while SPB did not.
Conclusions
TPVB had the best analgesic efficacy following VATS, though the analgesic efficacy of ESPBs was comparable. However, further studies are needed to determine the optimal regional analgesia technique to improve postoperative pain control following VATS.

OBJECTIVES:
The escalating burden of cardiovascular disease (CVD) is a critical public health issue worldwide. CVD, especially acute myocardial infarction (AMI) and stroke, is the leading contributor to morbidity and mortality in Korea. We aimed to develop algorithms for identifying AMI and stroke events from the National Health Insurance Service (NHIS) database and validate these algorithms through medical record review.
METHODS:
We first established a concept and definition of “hospitalization episode,” taking into account the unique features of health claims-based NHIS database. We then developed first and recurrent event identification algorithms, separately for AMI and stroke, to determine whether each hospitalization episode represents a true incident case of AMI or stroke. Finally, we assessed our algorithms’ accuracy by calculating their positive predictive values (PPVs) based on medical records of algorithm- identified events.
RESULTS:
We developed identification algorithms for both AMI and stroke. To validate them, we conducted retrospective review of medical records for 3,140 algorithm-identified events (1,399 AMI and 1,741 stroke events) across 24 hospitals throughout Korea. The overall PPVs for the first and recurrent AMI events were around 92% and 78%, respectively, while those for the first and recurrent stroke events were around 88% and 81%, respectively.
CONCLUSIONS
We successfully developed algorithms for identifying AMI and stroke events. The algorithms demonstrated high accuracy, with PPVs of approximately 90% for first events and 80% for recurrent events. These findings indicate that our algorithms hold promise as an instrumental tool for the consistent and reliable production of national CVD statistics in Korea.

CD99 signaling is crucial to a diverse range of biological functions including survival and proliferation. CD99 engagement is reported to augment activator protein-1 (AP-1) activity through mitogen-activated protein (MAP) kinase pathways in a T-lymphoblastic lymphoma cell line Jurkat and in breast cancer cell lines. In this study, we report that CD99 differentially regulated AP-1 activity in the human myeloma cell line RPMI8226. CD99 was highly expressed and the CD99 engagement led to activation of the MAP kinases, but suppressed AP-1 activity by inducing the expression of basic leucine zipper transcription factor, ATF-like (BATF), a negative regulator of AP-1 in RPMI8226 cells. By contrast, engagement of CD99 enhanced AP-1 activity and did not change the BATF expression in Jurkat cells. CD99 engagement reduced the proliferation of RPMI8226 cells and expression of cyclin 1 and 3. Overall, these results suggest novel CD99 functions in RPMI8226 cells.

Purpose:
To compare long-term disease-free survival (DFS) between patients receiving tegafur/gimeracil/oteracil (S-1) or capecitabine plus oxaliplatin (CAPOX) adjuvant chemotherapy (AC) for gastric cancer (GC).
Materials and Methods:
This retrospective multicenter observational study enrolled 983 patients who underwent curative gastrectomy with consecutive AC with S-1 or CAPOX for stage II or III GC at 27 hospitals in Korea between February 2012 and December 2013. We conducted propensity score matching to reduce selection bias. Long-term oncologic outcomes, including DFS rate over 5 years (over-5yr DFS), were analyzed postoperatively.
Results:
The median and longest follow-up period were 59.0 and 87.6 months, respectively. DFS rate did not differ between patients who received S-1 and CAPOX for pathologic stage II (P=0.677) and stage III (P=0.899) GC. Moreover, hazard ratio (HR) for recurrence did not differ significantly between S-1 and CAPOX (reference) in stage II (HR, 1.846; 95% confidence interval [CI], 0.693–4.919; P=0.220) and stage III (HR, 0.942; 95% CI, 0.664–1.337; P=0.738) GC. After adjustment for significance in multivariate analysis, pT (4 vs. 1) (HR, 11.667; 95% CI, 1.595–85.351; P=0.016), pN stage (0 vs. 3) (HR, 2.788; 95% CI, 1.502–5.174; P=0.001), and completion of planned chemotherapy (HR, 2.213; 95% CI, 1.618–3.028; P<0.001) were determined as independent prognostic factors for DFS.
Conclusions
S-1 and CAPOX AC regimens did not show significant difference in over-5yr DFS after curative gastrectomy in patients with stage II or III GC. The pT, pN stage, and completion of planned chemotherapy were prognostic factors for GC recurrence.
