Purpose: Fluid therapy for diarrhea-induced dehydration inadvertently increases emergency department length of stay (EDLOS). To prevent this delay, we investigated the usefulness of triage using point-of-care (POC) lactate in infants with diarrhea. Methods: This study was performed on infants with diarrhea who visited the emergency department from January 2019 through December 2020. According to the POC lactate concentration and the Korean Triage and Acuity Scale (KTAS) level, the infants were separately divided into the low (< 2 mmol/L), moderate (2-3.9), and high (≥ 4) lactate groups and the mild (KTAS 4-5) and severe (1-3) groups, respectively. Using these 2 group designations, we compared variables regarding the emergency medicine resource use and outcomes. To predict the prolonged EDLOS (≥ median value) we performed logistic regression and receiver operating characteristic analyses. Results: A total of 540 infants were included. The median of EDLOS was 169 minutes (interquartile range, 103-220). Fluid therapy was more frequently performed in the high lactate group than in the low-moderate lactate groups (85.0% vs. 60.4%-73.6%; P = 0.025). The high lactate and severe groups respectively showed higher rates of hospitalization (40.0% vs. 3.8%-7.6% [P < 0.001] and 10.9% vs. 1.4% [P = 0.015]), and longer median EDLOS (259 minutes vs. 147-178 [P < 0.001] and 185 vs. 131 [P = 0.001]) compared to the low-moderate lactate and mild groups. Compared to the KTAS, lactate is more strongly associated with the prolonged EDLOS (lactate, adjusted odds ratio, 4.80 [95% confidence interval, 1.87-15.34] vs. KTAS, 3.52 [1.90-6.54]). The areas under curve for lactate and for the KTAS were 0.66 (0.60-0.73) and 0.62 (0.55-0.69), respectively (P = 0.058). Conclusion In infants with diarrhea, POC lactate can be a predictor of emergency medicine resource use and outcomes.

PURPOSE: The aim of this study is to investigate the quality of basic life support (BLS) information for primary Korean-speaking individuals on the internet.METHODS: Using the Google © search engine, we searched for the terms ‘CPR’, ‘cardiopulmonary resuscitation (in Korean)’ and ‘cardiac arrest (in Korean)’. The accuracy, reliability and accessibility of web pages was evaluated based on the 2015 American heart association(AHA) guidelines for CPR & emergency cardiovascular care, the health on the net foundation code of conduct and Korean web content accessibility guidelines 2.1, respectively.RESULTS: Of the 178 web pages screened, 50 met criteria for inclusion. The overall quality of BLS information was not enough (median 5/7, IQR 4.75-6). 23(36%) pages were created in accordance with 2010 AHA guidelines. Only 24(48%) web pages educated on how to use the automated electrical defibrillator. The attribution and transparency of the reliability of pages was relatively low, 20(40%) and 16(32%). The web accessibility score was relatively high.CONCLUSION: A small of proportion of internet web pages searched by Google have high quality BLS information for a Korean-speaking population. Web pages based on past guideline were still being searched. The notation of the source of CPR information and the transparency of the author should be improved. The verification and evaluation of the quality of BLS information exposed to the Internet are continuously needed.

BACKGROUND: Early thrombolysis with intra-arterial urokinase(UK) or intravenous(IV) t-PA may be beneficial for patients with acute ischemic stroke, but this therapy is unavailable in some circumstances and cannot be applied in the cases of late admission. Thus, continuous IV UK infusion has been applied empirically in many hospitals of our country. However, the therapeutic efficacy of this therapy is not known yet. In this study, we investigated the safety and the clinical effect of continuous IV UK infusion. METHOD: 68 patients with acute supratentorial ischemic stroke within 3 days of onset received 6 x 105units of UK daily by continuous infusion for 5 days without loading dose. We estimated European stroke scale (ESS) and Barthel index score (BIS) prior to therapy, on day 1, 3 and 7 after the start of UK, and on the day of discharge. RESULTS: The ESS and BIS were improved in most patients after the therapy. There are no differences in therapeutic effects among the various stroke subtypes and the starting times of therapy after onset. Out of 10 TIA patients, 9 patients did not undergo further TIA and only one patient had complete infarction during UK infusion. Complications were noted in 7(10.3%) patients. But these complications were all minimal. CONCLUSION: As this study was just an open clinical trial, we could not conclude about definite efficacy of continuous IV UK infusion in acute ischemic stroke. However, this therapy might be at least acceptable safe regimen and deserves to be performed in multicenter double-blind controlled trials to clarify the efficacy.

Herpetic laryngitis is extremely rare in healthy adults. The local factors that increase susceptibility to herpes simplex virus include irradiation on the head and neck area. A 66-year-old man who had history of supraglottic cancer had voice change 4 years after the radiotherapy. On laryngscopic examination, the erosive mucosal lesion was found on his left vocal fold. A pathologic examination of the lesion by suspension laryngoscopy revealed that the lesion was herpetic laryngitis, which was confirmed by immunohistochemical stain as herpes simplex virus. Herpetic laryngitis should be in the index of differential diagnosis in patients with laryngitis who have the history of irradiation on the neck.

BACKGROUND: Glycemic profile has traditionally been with the use of HbAlc over a 2 to 4 month period. Recently, serum fructosamine is highly sensitive to acute metabolic deterioration(period 2 to 3 weeks), and is suitable for automation, allowing multiple assays with minimal effort. In some report, despite evidence suggesting a reduction in serum albumin level with increasing age, serum fructosamine was strongly correlated with HbAlc in elderly diabetic patients. This study was conducted to define the correlation between fructosamine and other parameters in elderly diabetic patients. METHODS: The study group consisted of 56 elderly patients(age range : 66-85 years, group A) and 58 adult patients(age range: 18-64 years, group B), who were stable over recent 2 months in fasting glucose values and serum albumin levels. Fructosamine was measured in 114 diabetic patients. The measured levels were related to HbAlc and fructosamine/albumin index(FAI). RESULTS: 1) There was significant correlation between HbAlc and fructosamine in all diabetic patients(r=0.705, p=0.0001). The correlation between HbAlc and fructosamine was stronger in group A than in group B [group A: r=0.831, group B: r=0.367, p=0.0001](p<0.05). 2) The correlation between HbAlc and FAI was significantly stronger compared to that between HbAlc and fructosamine in elderly diabetic patients(p<0.05). 3) Glycation ratio provides a vector-like insight into the recent trend of glycemia, and Glycation ratio was stable in all diabetic patients. CONCLUSIONS: Our study suggests that correlation between HbAlc and fructosamine in elderly daibetic patients was significantly lower in adult diabetic patients. Further studies are needed to determine the ultimate values of this test in the clinical management of elderly patient with diabetes.

BACKGROUND: The correlation between the high resolution computed tomography(HRCT) emphysema score and the physiologic parameters including resting and exercise pulmonary function test was investingated in 14 patients(60.6±10.3 years) with pulmonary emphysema. METHODS: The patients underwent a HRCT, a resting pulmonary function test, and incremental exercise testing(cycle ergometer, 10 W/min). Computed tomography scans were obtained on a GE highlight at 10 mm intervals using 10 mm collimation, from the apex to the base after a full inspiration. The emphysema scores wer determined by a CT program 'Density mask' outlining the areas with attenuation values less than -900 HU, indicating the emphysema areas, and providing an overall percentage of lung involvement by emphysema. RESULTS: Among the resing PFT parameters, only the diffusing capacity(r=-0.75) and PaO2 (r=-0.66) correlated with the emphysema score(p<0.05). Among the exercise test parameers, the emphysema score correlated significantly with the maximum power(r=-0.74), maximum oxygen consumption(r=-0.68), anaerobic threshold(V-slope method : r=-0.69), maximal O2-pulse(r=-0.73), and the physiologic dead space ratio at the maximum workload(r=-0.80)(p<0.01). CONCLUSION: We could find that exercise testing parameters showed a much better correlation with the HRCT emphysema score, which is known to have a good correlation with the pathologic severity than the resting PFT parameters. Therefore it is suggested that exercise testing is superior to resting PFT for estimating in the estimation of the physiologic disturbance in emphysema patients.

BACKGROUND: Histological analysis of tuberculosis shows a spectrum of findings, from well formed granulmatous inflammation with few bacilli in patient with normal immune response to M. tuberculosis to poorly formed granulomatous inflammation with many bacilli in patient with defective immune response. To evaluate the degree of immune response to M. tuberculosis, we studied the histologic features, including the presence of acid fast bacilli(AFB) in lymph node of patients with cervical tuberculous lymphadenitis, and compared them with clinical characteristics. METHODS: We reviewed the histologic features of 33 cases of cervical tuberculous lymphadenitis and processed the excised nodes for auramine-rhodamine staining to detect AFB. The AFB positivity in tissue was compared with the histologic features(degree of granuloma formation, presence of caseation necrosis, presence of neutrophilic infiltration) and clinical characteristics (lymph node size, duration of symptom, presence of local symptom or radiologic evidence of pulmonary tuberculosis). RESULTS: 1) The mean age at diagnosis was 42.4 years, and male to female ratio was 1 : 45. 2) Histologically, all cases showed well formed granuloma and variable degrees of caseation necrosis, and 39% of the cases showed neutrophilic infiltration in the granulomatous inflammation. 3) AFB were confirmed in 52% of the cases, and they were found extracellularly and at the periphery of caseation necrosis. 4) There was no association between AFB Positivity and histological features or clinical characteristics. CONCLUSION: Cervical tuberculous lymphadenitis showed well formed granulomatous inflammation with caseation necrosis, and there was no association between AFB positivity in the tissue and histological or clinical characteristics.

PURPOSE: We report a case of successfully treating bilateral conjunctival-corneal intraepithelial neoplasia (CCIN) with surgical excision and adjunctive cryotherapy. CASE SUMMARY: A 74-year-old male visited our clinic for bilateral foreign body sensation and decreased visual acuity. His initial best corrected visual acuity was 20/50 in the right eye and 20/30 in the left eye. The right eye showed a 9 mm x 11 mm sized, gray-opaque limbal lesion from approximately the 7-o'clock position to the 11-o'clock position with spreading onto the cornea and conjunctiva. Biomicroscopy revealed a 6 mm x 7.5 mm sized minimally elevated, opaque lesion from the 3-o'clock to the 5-o'clock position extending to the central cornea in the left eye. The corneal lesion was well demarcated, opaque, and minimally elevated with bilateral focal pigmentation. Conjunctival lesions were finely vascularized and slightly elevated with melanocytic pigmentation. An excisional biopsy was performed to confirm the diagnosis and for therapeutic purposes, followed by an adjunctive cryotherapy. Postoperative corrected visual acuity improved up to 20/25 bilaterally and the patient had no recurrence 8 months after surgery. CONCLUSIONS: Bilateral conjunctival-corneal intraepithelial neoplasia is a rare condition. We report successful treatment and control of recurrence in a patient with bilateral conjunctival-corneal intraepithelial neoplasia using conventional surgical excision and adjuvant cryotherapy rather than topical chemotherapy.
