Objectives Acute cholecystitis is a gallbladder inflammation, and the Tokyo Guidelines 2018 (TG18) can be used to predict its presence and severity with high sensitivity and specificity. However, TG18 grading require the collection of excessive parameters. Monocyte distribution width (MDW) is a parameter used to detect sepsis early. Therefore, we investigated the correlation between MDW and cholecystitis severity. Methods We conducted a retrospective study of patients with cholecystitis admitted to our hospital from November 1, 2020, to August 31, 2021. The primary outcome was severe cholecystitis analyzed as a composite of intensive care unit (ICU) admission and mortality. The secondary outcomes were length of hospital stay, ICU stay, and TG18 grade. Results A total of 331 patients with cholecystitis were enrolled in this study. The average MDWs for TG18 grades 1, 2, and 3 were 20.21 ± 3.99, 20.34 ± 3.68, and 25.77 ± 6.61, respectively. For patients with severe cholecystitis, the average MDW was 25.42 ± 6.83. Using the Youden J statistic, we set a cutoff MDW of 21.6. Multivariate logistic regression revealed that patients with an MDW≥21.6 had a higher risk of severe cholecystitis (odds ratio=4.94; 95 % CI, 1.71–14.21; p=0.003). The Cox model revealed that patients with an MDW≥21.6 were more likely to have a prolonged hospital stay. Conclusions MDW is a reliable indicator of severe cholecystitis and prolonged length of stay. Additional MDW testing and a complete blood count may provide simple information for predicting severe cholecystitis early.

Background Colonic diverticulitis is a leading cause of abdominal pain. The monocyte distribution width (MDW) is a novel inflammatory biomarker with prognostic significance for coronavirus disease and pancreatitis; however, no study has assessed its correlation with the severity of colonic diverticulitis. Methods This single-center retrospective cohort study included patients older than 18 years who presented to the emergency department between November 1, 2020, and May 31, 2021, and received a diagnosis of acute colonic diverticulitis after abdominal computed tomography. The characteristics and laboratory parameters of patients with simple versus complicated diverticulitis were compared. The significance of categorical data was assessed using the chi-square or Fisher’s exact test. The Mann–Whitney U test was used for continuous variables. Multivariate regression analysis was performed to identify predictors of complicated colonic diverticulitis. Receiver operator characteristic (ROC) curves were used to test the efficacy of inflammatory biomarkers in distinguishing simple from complicated cases. Results Of the 160 patients enrolled, 21 (13.125%) had complicated diverticulitis. Although right-sided was more prevalent than left-sided colonic diverticulitis (70% versus 30%), complicated diverticulitis was more common in those with left-sided colonic diverticulitis (61.905%, p = 0.001). Age, white blood cell (WBC) count, neutrophil count, C-reactive protein (CRP) level, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and MDW were significantly higher in the complicated diverticulitis group (p < 0.05). Logistic regression analysis indicated that the left-sided location and the MDW were significant and independent predictors of complicated diverticulitis. The area under the ROC curve (AUC) was as follows: MDW, 0.870 (95% confidence interval [CI], 0.784–0.956); CRP, 0.800 (95% CI, 0.707–0.892); NLR, 0.724 (95% CI, 0.616–0.832); PLR, 0.662 (95% CI, 0.525–0.798); and WBC, 0.679 (95% CI, 0.563–0.795). The MDW had the largest AUC for diagnosing complicated diverticulitis; when the MDW cutoff was 20.38, the sensitivity and specificity were maximized to 90.5% and 80.6%, respectively. Conclusions Patients with complicated diverticulitis were significantly older and predominantly had left-sided colonic diverticulitis. A large MDW was a significant and independent predictor of complicated diverticulitis. The MDW may aid in planning antibiotic therapy for patients with colonic diverticulitis in the emergency department.

This study compared the casualties and types of rescues conducted on the main climbing route (MCR) and accessory climbing routes (ACRs) in Yushan National Park (YSNP) between 2008 and 2019.We collected the following information for all documented mountain rescue operations conducted on the MCRs and ACRs in YSNP between 2008 and 2019: accident location, casualty type, victim number, and type of rescue. The victims were categorized as to injury, illness, mortality, or no medical problem (NMP) groups according to their condition at the time of rescue.Two-hundred forty-four rescue operations involving 329 victims were conducted during the 12-y study period. Among them, 105 (32%) did not require medical treatment, 102 (31%) were injured, 82 (25%) were ill, and 40 (12%) were deceased. Of the 82 individuals with illness, 69 (84%) had acute altitude sickness. The accident and mortality rates on the ACRs were significantly higher than those on the MCR (P0.001; χAcute altitude sickness accounted for most of the rescues. ACRs had higher injury and mortality rates and required more helicopter-based rescues for patients who did not have medical problems. This study may serve as a reference to reduce casualties and overuse of helicopters by educating tourists on the appropriate use of maps and the evaluation of trails in relation to weather conditions.

Background: Discussing the quality measurements based on interrupted time series in ischemic stroke, delays are often attributed to weekends effect. This study compared the metrics and outcomes of emergent endovascular thrombectomy (EST) during working hours versus non-working hours in the emergency department of an Asian medical center. Methods: A total of 297 patients who underwent EST between January 2015 and December 2018 were retrospectively included, with 52.5% of patients presenting during working hours and 47.5% presenting during nights, weekends, or holidays. Results: Patients with diabetes were more in non-working hours than in working hours (53.9% vs. 41.0%; p=0.026). It took longer during nonworking hours than working hours in door-to -image times (13 min vs. 12 min; p=0.04) and door-to-groin puncture times (median: 112 min vs. 104 min; p=0.042). Significant statistical differences were not observed between the two groups in neurological outcomes, including successful reperfusion and complications such as intracranial hemorrhage and mortality. However, the change in National Institute of Health Stroke Scale (NIHSS) scores in 24 hours was better in the working-hour group than in the nonworking-hour group (4 vs. 2; p=0.058). Conclusions: This study revealed that nonworking-hour effects truly exist in patients who received EST. Although delays in door-to-groin puncture times were noticed during nonworking hours, significant differences in neurological functions and mortality were not observed between working and non-working hours. Nevertheless, methods to improve the process during non-working hours should be explored in the future.

As a source of growth factors for expediting wound healing and tissue regeneration, plasma-rich plasma (PRP) has been extensively applied in diverse fields including orthopaedics, ophthalmology, oral and maxillofacial surgery, dentistry, and gynaecology. However, the function of PRP in metabolic regulations remains enigmatic. A standardized method was devised herein to enrich growth factors and to lyophilize it as enhanced PRP (ePRP) powder, which could become ubiquitously available without mechanical centrifugation in clinical practice. To identify metabolic reprogramming in human dermal fibroblasts under ePRP treatment, putative metabolic targets were identified by transcriptome profiling and validated for their metabolic effects and mechanism. ePRP does not only promote wound healing but re-aligns energy metabolism by shifting to glycolysis through stimulation of glycolytic enzyme activity in fibroblasts. On the contrary, oxygen consumption rates and several mitochondrial respiration activities were attenuated in ePRP-treated fibroblasts. Furthermore, ePRP treatment drives the mitochondrial resetting by hindering the mitochondrial biogenesis-related genes and results in a dampened mitochondrial mass. Antioxidant production was further increased by ePRP treatment to prevent reactive oxygen species formation. Besides, ePRP also halts the senescence progression of fibroblasts by activating SIRT1 expression. Importantly, the glycolytic inhibitor 2-DG can completely reverse the ePRP-enhanced wound healing capacity, whereas the mitochondrial inhibitor oligomycin cannot. This is the first study to utilize PRP for comprehensively investigating its effects on the metabolic reprogramming of fibroblasts. These findings indicate that PRP’s primary metabolic regulation is to promote metabolic reprogramming toward glycolytic energy metabolism in fibroblasts, preserving redox equilibrium and allowing anabolic pathways necessary for the healing and anti-ageing process.

BACKGROUND: Acute mountain sickness (AMS) often occurs in individuals who rapidly travel above 2,500 m. As the convenience of traveling and the development of mountain sports increase, AMS will become an increasingly important public health problem. However, no method to effectively predict AMS before it occurs is currently available. METHODS: This post hoc study investigated whether the 3-Minute Step Test (3MST), which evaluates physical fitness, is predictive of AMS development. The data collected in “Rhodiola crenulata extract for prevention of AMS: a randomized, double-blind, placebo-controlled, crossover trial” was used in the analysis. This study collected 204 observations of 102 participants who made two ascents of Hehuan Mountain (3,100 m) by bus within a 3-month period. Participants completed the 3MST at 250 m (before ascent) and 3,100 m (on Hehuan Mountain). The presence of AMS was accessed using the Lake Louise scoring system. RESULTS: AMS was identified in 124 observations (60.78%). In the univariate analysis, the pre-departure 3MST score (at 250 m) was not significantly associated with AMS (p = 0.498), but the 3MST score measured at 3,100 m, ascent number, pulse rate at 3,100 m, and saturation of peripheral oxygen (SpO(2)) measured at 3,100 m were significantly correlated with the occurrence of AMS (p = 0.002, 0.039, 0.005, < 0.001, respectively). In a further multivariate analysis, only SpO(2) measured at 3,100 m had a significant association with AMS (p = 0.016 and 0.006, respectively). The trend analysis showed that for every 1-point increase in the 3MST score at 3,100 m, the AMS decreased by 4% (adjusted odds ratio [AOR] = 0.96, 95% confidence interval [CI] = 0.92–1.01). CONCLUSION: The 3MST score cannot be a predictor of AMS, but it may have a potential role in predicting ascent safety in high-altitude areas.

To examine the effect of ascent rate on the induction of acute mountain sickness (AMS) in young adults during a climb to Jiaming Lake (3350 m) in Taiwan.Prospective, nonrandomized.Climb from 2370 to 3350 m.Young adults (aged 18 to 26 years) (N = 91) chose to participate in either the fast ascent (3 days; n = 43) or slow ascent (4 days; n = 48) group (1 and 2).Two criteria were used to define AMS. A Lake Louise score ≥3 and Lake Louise criteria [in the setting of a recent gain in altitude, the presence of headache and at least 1 of gastrointestinal discomfort (anorexia, nausea, or vomiting), fatigue or weakness, dizziness or lightheadedness, or difficulty sleeping].Heart rate, blood oxygen saturation (SaO2), and symptoms of AMS were monitored each morning and evening.Baseline characteristics were similar between groups, except for significant differences in history of alcohol consumption (P = 0.009) and climbing experience above 3000 m (P0.001). The incidence of AMS was not associated with the rate of ascent. Acute mountain sickness was most prevalent in group 1 on day 2 in the evening and in group 2 on day 3 in the evening. In both groups, AMS correlated with the initial reduction in SaO2. Body mass index (BMI)24 kg/m was identified as a significant risk factor for AMS.The development of AMS was closely associated with an initial reduction in SaO2. A BMI24 kg/m also contributed to the occurrence of AMS.These findings indicate that factors other than ascent rate should be considered when trying to ameliorate the risk of AMS.

The relationship of hypothyroidism and Menière's disease (MD) has been discussed before, yet not well documented. Our study aims to investigate the correlation of both diseases. This is a retrospective cohort study based on data from the LHID2000 (Longitudinal Health Insurance Database 2000), a subset of the Taiwan National Research Health Insurance Database that contains claims data for the 2000 to 2011 period. A total of 27,050 patients were included in this study, 5410 of whom had received a hypothyroidism diagnosis. The prevalence of MD was high in patients with hypothyroidism (95% confidence interval [CI]: 1.14–1.51), especially in those older than 50 years old (P

Cardiogenic shock is defined by tissue hypoperfusion due to heart failure. The manifestations of acute right ventricular (RV) failure include a distended jugular vein and hypotension, but not rales. The causes of isolated acute RV failure include RV infarction, pulmonary embolism, cardiac tamponade, congenital disease, and valvular heart disease. Rupture of a sinus of Valsalva aneurysm (SVA) is rarely seen in emergency departments (EDs). We report a 46 year-old male who suffered from SVA rupture triggering acute RV failure and cardiogenic shock.

Purpose This study investigated whether alcoholic intoxication (AI) increases the risk of inflammatory bowel disease (IBD) by using a population-based database in Taiwan. Methods This retrospective matched-cohort study included 57 611 inpatients with new-onset AI (AI cohort) and 230 444 randomly selected controls (non-AI cohort). Each patient was monitored for 10 years to individually identify those who were subsequently diagnosed with Crohn disease (CD) and ulcerative colitis (UC) during the follow-up period. Cox proportional hazard regression analysis was conducted to determine the risk of IBD in patients with AI compared with controls without AI. Results The incidence rate of IBD during the 10-year follow-up period was 2.69 per 1 000 person-years and 0.49 per 1 000 person-years in the AI and non-AI cohorts, respectively. After adjustment for age, sex, and comorbidity, the AI cohort exhibited a 3.17-fold increased risk of IBD compared with the non-AI cohort (hazard ratio [HR] = 3.17, 95% confidence interval [CI] = 2.19–4.58). Compared with the non-AI cohort, the HRs of CD and UC were 4.40 and 2.33 for the AI cohort, respectively. After stratification for the severity of AI according to the duration of hospital stay, the adjusted HRs exhibited a significant correlation with the severity; the HRs of IBD were 1.76, 6.83, and 19.9 for patients with mild, moderate, and severe AI, respectively (p for the trend < .0001). Conclusion The risk of IBD was higher in patients with AI and increased with the length of hospital stay.

Objective The purpose of this trial was to establish whether changes in resting oxygen saturation (Spo 2 ) during ascent of Jade Mountain is useful in predicting acute mountain sickness (AMS). AMS–risk factors were also assessed. Methods A prospective trial was conducted on Jade Mountain, Taiwan from October 18 to October 27, 2008. Resting oxygen saturation (Spo 2 ) and heart rate (HR) were measured in subjects at the trail entrance (2610 m), on arrival at Paiyun Lodge (3402 m) on day 1, and at Paiyun Lodge after reaching the summit (3952 m) the next day (day 2). AMS was diagnosed with Lake Louise criteria (AMS score ≥4). A total of 787 subjects were eligible for analysis; 286 (32.2%) met the criteria for AMS. Results Subjects who developed AMS had significantly lower Spo 2 than those who did not at the trail entrance (93.1% ± 2.1% vs 93.5% ± 2.3%; P = .023), on arrival at Paiyun Lodge on day 1 (86.2% ± 4.7% vs 87.6% ± 4.3%; P P P 3000 m) travel in the previous 3 months (29.9% vs 37.1%; P = .004). Conclusions Subjects with AMS had a lower Spo 2 than those without AMS; however, the differences between the 2 groups were not clinically significant. The results of this study do not support the use of pulse oximetry in predicting AMS on Jade Mountain.

Patients with chronic spontaneous urticaria (CSU) often have sleep disorders (SDs) because of pruritus. However, SDs might also contribute to the development of CSU. Here, we present the first population-based cohort study on the association between SDs and subsequent CSU development. This study investigated whether SDs increase the risk of CSU by using a population-based database in Taiwan. This retrospective matched-cohort study included 105,892 patients with new-onset SDs (SD cohort) and 105,892 randomly selected controls (control cohort). Each patient was monitored for 10 years to individually identify patients who were subsequently diagnosed as having CSU during the follow-up period. A Cox proportional hazard regression analysis was conducted to determine the risk of CSU in patients with SDs compared with the controls. All relevant comorbidities were more prevalent in the SD cohort than in the control cohort (P

High Alt. Med Biol. 10:77-82, 2009.-Medical problems requiring mountain rescue in densely populated and low-latitude locations like Taiwan have rarely been studied or discussed. The purpose of this research was to examine mountain-rescue operations that occurred in Yu-Shan National Park Taiwan from 1985 to 2007. Of 186 mountain-rescue operations, 128 involved medical problems (illnesses or injuries). Of the medical problems, 62% involved trauma and 41% involved illness. Ninety-nine ground rescues, 14 helicopter rescues, 38 combination ground and helicopter rescues, and 20 rescues using unclear methods were conducted, and the remaining 15 rescue operations did not involve visitors. In the 186 rescue operations, 330 visitors were rescued, 240 of them survived, 66 were dead, and 24 had an unclear outcome. Factors that affected the type of injury or the probability of survival included the activity, altitude, composition of the visitor group, weather, and occurrence of natural disasters. Mountain-rescue operations in which both ground and helicopter rescue were utilized were more successful. Our retrospective findings indicate that wilderness emergency services should have the capability of performing rescues in rugged terrain and be flexible in their approach to any situation arising in mountainous regions; proper training of onboard helicopter medical personnel is also necessary. In conclusion, we recommend setting up a standard system for reporting mountain- rescue operations, with statistics compiled annually.

This study investigated whether alcohol intoxication (AI) increases the risk of venous thromboembolism (VTE) by using the Taiwan National Health Insurance Research Database (NHIRD). Using data from the NHIRD, we assembled 61,229 patients with acute AI and randomly selected 244,916 controls. Each patient was monitored from 2000 to 2011 to identify those who were subsequently diagnosed with deep vein thrombosis (DVT) and pulmonary embolism (PE). Cox proportional hazard regression analysis was conducted to determine the risk of VTE in the patients with AI compared with the controls. The incidence rate of DVT during the 10 years follow-up period was 9.36 per 10,000 person-years and 2.07 per 10,000 person-years in the AI and non-AI cohorts, respectively. Moreover, the incidence rate of PE was 4 per 10,000 person-years in the AI cohort and 0.93 in the non-AI cohort. After adjustment for age, sex, and comorbidities, the risks of DVT and PE were 3.40 [95% confidence interval (CI) = 2.83–4.08] and 3.53 (95% CI = 2.69–4.65)-fold higher in the AI cohort than in the non-AI cohort. An increased incidence of VTE was observed among patients with AI. Therefore, physicians should carefully estimate the risk of VTE in patients with AI.

Objective The objective of this study is to determine the association between the duration of high-altitude (>3000 m) pre-exposure and acute mountain sickness (AMS) incidence. Methods A prospective observational study was conducted on 2 random days each month from April 2007 to March 2008 at Paiyun Lodge (3402 m), Jade Mountain, Taiwan. Demographic data, prior AMS history, symptoms, and scores and the days and times of high-altitude pre-exposure within the preceding 2 months were obtained from lowland ( Results Totally, 1010 questionnaires were analyzed; 106, 76, and 828 trekkers had pre-exposure lasting at least 3 days (group 1), less than 3 days (group 2), and 0 days (group 3), respectively. Acute mountain sickness incidence was significantly higher in groups 2 and 3 than in group 1 (21.70%, 35.53%, 37.08%, respectively; P = .008). Logistic regression analysis indicated a significantly lower AMS risk in group 1 (group 1, P = .004; odds ratio [OR], 0.479; 95% confidence interval [CI], 0.290-0.791; group 2, P = .226; OR, 0.725; 95% CI, 0.430-1.221). In group 1, 28 and 78 trekkers had single and intermittent multiple pre-exposure, respectively. There was no difference in the incidence or severity of AMS symptoms between single and intermittent multiple pre-exposure (AMS, P = .838; headache, P = .891; dizziness or lightheadedness, P = .414; fatigue and/or weakness, P = .957; gastrointestinal symptoms, P = .257; difficulty sleeping, P = .804; AMS score, P = .796). Conclusions High-altitude pre-exposure lasting at least 3 days within the preceding 2 months was associated with a significant lower AMS incidence during a subsequent ascent among Jade Mountain trekkers.

Purpose Previous studies have reported conflicting results on the association between Helicobacter pylori infection and osteoporosis. A few studies have discussed the influence of H. pylori eradication therapy on bone mineral density. Methods We assessed the prevalence of osteoporosis among the H. pylori-infected population in Taiwan and the influence of early and late H. pylori eradication therapy on bone mineral density. Results Using data from Taiwan's National Health Insurance Research Database, we identified 5,447 patients who received H. pylori eradication therapy from 2000 to 2010 and 21,788 controls, frequency-matched according to age, sex, and year of receiving H. pylori eradication therapy. Those who received H. pylori eradication therapy were divided into two groups based on the time interval between the diagnosis of a peptic ulcer and commencement of eradication therapy. The risk of developing osteoporosis was higher in the early H. pylori treatment cohort (hazard ratio [HR] = 1.52, 95% confidence interval [CI] = 1.23–1.89) and late H. pylori treatment cohort (HR = 1.69, 95% CI = 1.39–2.05), compared with the risk in the control cohort. When followed for less than 5 years, both the early and late cohorts had a higher risk of developing osteoporosis (HR = 1.69, 95% CI = 1.32–2.16 and HR = 1.72, 95% CI = 1.38–2.14). However, when the follow-up period was over 5 years, only the late eradication group exhibited a higher incidence of osteoporosis (HR = 1.62, 95% CI = 1.06–2.47). Conclusion The development of osteoporosis is complex and multi-factorial. Via this population-based cohort study and adjustment of possible confounding variables, we found H. pylori infection may be associated with an increased risk of developing osteoporosis in Taiwan. Early eradication could reduce the influence of H. pylori infection on osteoporosis when the follow-up period is greater than 5 years. Further prospective studies are necessary to discover the connection of H. pylori and osteoporosis.

Refractory cardiac arrhythmia, which has a poor response to defibrillation and antiarrhythmia medication, is a complicated problem for clinical physicians during resuscitation. Extracorporeal membrane oxygenation (ECMO) may be used to sustain life in this situation. ECMO is useful for cardiopulmonary resuscitation among patients suffering from cardiac arrest; the use of ECMO in this context is called E-cardiopulmonary resuscitation. However, a large-scale and nationwide survey of ECMO usage in cases involving refractory cardiac arrhythmia during resuscitation is lacking. We aimed to clarify the characteristics and efficacy of the application of ECMO in cases involving refractory cardiac arrhythmia during resuscitation by conducting a nationwide study. Using national insurance data from 1996 to 2011, 2702 patients who received defibrillation and amiodarone injections were selected. We excluded trauma patients (n = 316) and those aged1 day was higher risk of death (OR = 2.88, 95% CI = 1.27–6.53). In our retrospective case control study in refractory cardiac arrhythmia patients, ECMO supportive in high propensity score patients showed improving the overall survival rate but ECMO support for >1 day would be harmful. The evidence derived from this retrospective study using data from the national insurance system is generally of lower methodological evidence than that from randomized controlled trials because a retrospective study is subject to many biases due to lack of the necessary adjustments for possible confounding factors. Therefore, further investigation with a randomized clinical trial is needed to recommend ECMO as a routine in this specific population of patients experiencing cardiac arrest and refractory VT and VF.

Background: Acute mountain sickness (AMS) is a pathophysiological symptom complex that occurs in high-altitude areas. The incidence of AMS on Jade Mountain, the highest peak in Taiwan (3952 m), has been reported to be ∼36%. There is a lack of data in children trekking at altitude in Taiwan. The purpose of this study was to determine the incidence, risk factors and symptoms of AMS in children trekking on Jade Mountain, Taiwan. Methods: This prospective cohort study included a total of 96 healthy non-acclimatized children aged 11–12 years who trekked from an elevation of 2600–3952 m in 3 days. The Lake Louise AMS score was used to record symptoms associated with AMS. Results: AMS were reported in 59% of children trekking on Jade Mountain over a 3 day period. AMS incidence increased significantly with increasing altitude. The most common AMS symptom was headache, followed by fatigue or weakness, difficulty sleeping, dizziness or lightheadedness and gastrointestinal symptoms. Children who had experienced upper respiratory infection (URI) within the 7 days before their trek tended to have a greater risk for development of AMS. AMS incidence did not significantly differ according to gender, recent acute gastroenteritis, menstruation and body mass index. Conclusions: The incidence of AMS in children trekking on Jade Mountain is greater than that observed in adults, and was associated with altitude and recent URI.

Alcohol use disorder (AUD) is considered a possible risk factor for irritable bowel syndrome (IBS); however, previous studies investigating the association between AUD and IBS have yielded inconsistent results. The study investigated whether AUD increases the risk of IBS by using a population-based database in Taiwan. This retrospective matched-cohort study included the health insurance claims data of 56,355 AUD inpatients and 225,420 randomly selected controls by frequency-matched for sex, age, and index year. Cox proportional hazards regression analysis was performed to measure the risk of IBS among AUD patients compared with non-AUD patients. During the follow-up period, the incidence rate ratio (IRR) of IBS had 12.3-fold (95% CI: 11.9–12.7) in the AUD patients than non-AUD patients and the adjusted hazard ratio (aHR) for IBS in the AUD patients was 5.51 (95% CI: 4.36–6.96). For several comorbidities, the risk of IBS was significantly higher in the AUD patients than in non-AUD patients, with aHRs of 2.14 (95% confidence interval [CI]: 1.19–3.84), 2.05 (95% CI: 1.06–3.96), and 2.91 (95% CI: 1.26–6.72) for sleep disorders, acute pancreatitis, and hepatitis B, respectively. When we stratified the severity of AUD according to the length of hospital stay, the aHRs exhibited a significant correlation (P

Introduction. Cresol is a phenol derivative used as a disinfectant worldwide. Acute cresol poisoning is potentially fatal as it may cause multiple organ failure. We present a case of acute cresol intoxication in a male patient to illustrate the effects of cresol poisoning. Case. A 42-year-old male presented with black urine, painless brownish dermal burns, and a strong carbolic acid odor. The patient was immediately resuscitated with adequate oxygenation and aggressive fluid resuscitation. He was subsequently admitted to the intensive care unit, where his treatment course was complicated by pneumonia, gastrointestinal bleeding, hepatic dysfunction, and acute renal failure. After receiving supportive intensive care, the patient recovered and was discharged with no sequelae. Conclusion. The distinctive clinical features of this case may be useful in diagnosis, because laboratory analytical methods for cresols are not routinely available at most hospitals.

Acute mountain sickness (AMS) is a pathophysiological symptom complex that occurs in high altitude areas. The AMS prevalence is reportedly 28% on Jade Mountain, the highest mountain (3952 m) in Taiwan. We conducted this study owing to the lack of annual epidemiological data on AMS in Taiwan. Between April 2007 and March 2008, 1066 questionnaires were completed by trekkers visiting Paiyun Lodge on Jade Mountain. Information in the questionnaire included demographic data, mountaineering experience, AMS history, and trekking schedule. Weather data were obtained from the Central Weather Bureau of Taiwan. The Lake Louise AMS score was used to record symptoms and diagnose AMS. The chi-square test or the Student t test was used to evaluate associations between variables and AMS. In our study, the AMS prevalence was 36%. It increased significantly at different rates at different locations on the Jade Mountain trail and varied significantly in different months. Rainy weather tended to slightly increase the incidence of AMS. A lower incidence of AMS was correlated with hig-altitude trekking experience or preexposure (p < 0.05), whereas a higher incidence of AMS was correlated with a prior history of AMS (p < 0.05). The trekkers with AMS were significantly younger, ascended faster from their residence to the entrance or to Paiyun Lodge, and ascended slower from the entrance to the Paiyun Lodge (p < 0.05), but the differences lacked clinical significance. No differences in the incidence of AMS based on blood type, gender, or obesity were observed. The most common symptom among all trekkers was headache, followed by difficulty sleeping, fatigue or weakness, gastrointestinal (GI) symptoms, and dizziness or lightheadedness. In conclusion, the AMS prevalence on Jade Mountain was 36%, varied by month, and correlated with trekking experience, preexposure, and a prior history of AMS. The overall presentation of AMS was similar to that on other major world mountains.

A 28-year-old woman presented at the emergency department (ED) with acute bilateral leg weakness and lost the ability to walk 1 day after noticing bilateral leg numbness and intermittent pleuritic pain for 3 weeks. Physical examination revealed bilateral decreased muscle strength with score 4 symmetrically in the legs and decreased deep tendon reflex. Laboratory tests indicated lymphopenia but no other grossly remarkable findings. Cerebrospinal fluid analysis demonstrated albuminocytologic dissociation. Electrophysiologic survey also indicated sensory-motor demyelinating polyneuropathy. The clinical picture was compatible with acute inflammatory demyelinating polyneuropathy (AIDP), the most prevalent form of Guillain-Barre syndrome (GBS). Plasma exchange was immediately arranged. After serial examination, pleuritic pain, persistent lymphopenia, positive immunologic findings of anti-DNA, and antinuclear antibodies led to a diagnosis of systemic lupus erythematosus (SLE). Prednisolone was added along with plasma exchange. The patient was able to walk after 2 weeks of therapy. Acute inflammatory demyelinating polyneuropathy presenting as the initial manifestation of SLE is rather rare. The precise mechanism of SLE-related AIDP remains unclear but is probably immune related. Although steroids are not recommended in the management of AIDP or GBS, patients with SLE-related AIDP may benefit from steroid therapy. This case highlights that early initiation of evaluation for SLE by ED physicians may facilitate correct diagnosis and better outcomes in patients presenting with GBS or AIDP in the ED.
