Objectives: Fournier’s gangrene (FG) is an devastating disease that affects the perineum and genitourinary region, and is commonly a result of poly-microbial infection. This study is aimed to determine the correlation between micrology and prognosis of FG in the past five years. Methods: This study was a retrospective cohort study that was designed to study the trends in micrology and prognosis of FG. From the PubMed database, articles published in the recent 5 years (from Jan1^st, 2009 to Dec 31^st, 2013) were reviewed. A total of 19 articles (each with n > 30 and with thorough data descriptions in the topic of Fournier's gangrene), were enrolled in this study. The consolidated data was further analyzed by commercial statistical software (SPSS for Windows). Results: The twenty-two studies have covered FG cases from year 1981 to 2011, with a mean duration of 9.2 years. The total number of cases is 4,365. Majority of the cases are male (84.1%). The mean age and mortality rate is 51.8 ± 5 years old and 11.1 ± 8.9%, respectivly. The most commonly found pathogen is poly-microbial organism (54%), followed by Escherichia coli (46.6%) and Streptococcus (36.8%). The major risk factors are diabetes (43.7%), Body mass index of > 30 (40.7%), and hypertension (38.1%). Mortality rate in older patient group (age > 51.8 years old) is significantly higher than those of the younger group (22% vs. 5.5%, p = 0.0001). Conclusions: Older patients with genital or perineal pain should be examined for crepitus dermis. When a patient is diagnosed with FG, swift consultation with surgeons and administration of broad-spectrum antibiotics are required in order to save the patient’s live.

Background: Chlorfenapyr is a widely used pesticide and is classified as moderately hazardous to human health. Ingestion usually leads to mortality in humans. However, chlorfenapyr toxicity has a variable course and mechanism of action. Case presentation: We report the case of a 79-year-old female who ingested chlorfenapyr with the intent to commit suicide. The liquid was ingested 2 hours before she was brought to our emergency department. Gastric lavage was immediately performed. On admission, laboratory examinations revealed mildly elevated liver enzyme and creatinine kinase levels. Acute fever occurred on day 7; on day 8, the patient died of progressive respiratory distress and conscious disturbance. Chlorfenapyr toxicity leads to high rates of mortality (75%) and causes damage to the liver and the nervous system. Conclusions: It is necessary to observe patients with chlorfenapyr toxicity for 3 weeks because no significant abnormalities occur in the early phase. The onset of fever and deterioration of consciousness is a warning sign of a sudden fatal outcome. We review the literature and discuss neurologic and cardiopulmonary impairment in the clinical course of chlorfenapyr poisoning.

In Taiwan, traditional herbal medication was included in Taiwan's National Health Insurance (NHI) system since 1996 and in 9 out of 10 hospitals have developed their own departments of traditional medicine. This study aims to address the herb-induced liver injury (HILI) after using herbal medicine on the relationship between age, gender, epidemiology, laboratory data, pathogenesis, mobility, and mortality. We searched the PubMed database with “hepatitis after herbal medicine” and “in human” till 2018 April and returned 163 articles in a systemic review manner. Two cases reports describing in-vitro liver injury were excluded. Reviews and articles without the detailed report, laboratory data and history were excluded from this study. In the end, there were 53 articles enrolled in this study. These enrolled literatures are from France (n = 13), Germany (n = 12), Switzerland (n = 5) United States of America (n = 4), Korea (n = 4), Hong Kong (n = 4), Greece (n = 3), China (n = 2), Canada (n = 1), Italy (n = 1), Thailand (n = 1), Finland (n = 1), Taiwan (n = 1), and Japan (n = 1). The data were analyzed with a commercial statistical software Stata/SE 12.0 program Stata Corporation, College Station, TX, USA. Statistical χ² tests were performed and the significance was set at a P value of less than .05 (2-tailed). The ages are ranged from 15 to 78 years with the mean ± SD (standard deviation) of 48.3 ± 16.2 years old. The majority of cases are female (n = 37). In elderly, man is more commonly seen than female in HILI (37.5% vs 10.5%, P = .02). Female is vulnerable to cholestatic type of HILI than male (21.1% vs 0.0%, P = .04). Of all the cases in HILI, using pure substance are more commonly seen than mixed substance (P = .02). In gender, male patients have higher alanine aminotransferase (GPT) (IU/L) level in HILI than female ones (1560 ± 819 vs 1047 ± 706, P = .03). In HILI, the female is more commonly seen than male, but less than male in the elderly. The pure substance more often happens to HILI than mixture substance. Female is predominant in the cholestatic type of HILI. The major prevalence of HILI is in Europe rather than Asia. HILI cases in Europe is 2.75-fold than in Asia. This could be due to fewer reports of the herb induced liver injury in Asia compared to Europe. Prevention of HILI is the best policy, because it needs to take 78 ± 59 days to recover.

Purple urine bag syndrome (PUBS) is rarely observed in clinical practice. The present study aimed to identify the epidemiological trends in PUBS in recent decades. A search of PubMed articles published between 1980 October and 2016 August was conducted, in which 106 articles (174 cases) described PUBS. Of these cases, 58 cases were excluded: 14 cases without mention of gender, 4 cases without description of age, 37 cases without mention of white blood cell (WBC) count, shock status, fever status or description of etiology, and 3 cases without information on mortality. The remaining 116 PUBS cases were collected and analyzed in the present study. The articles were divided into three groups by publication year: 1991 to 2000, 2001 to 2010 and 2011 to 2016. The chi(2) test was used for statistical analysis, with P= 65 years old). A total of 93.1% of cases had a urine pH >7 while 6.9% of cases had acidic urine (pH <7). Furthermore, although WBC count elevated progressively, the mortality rate of patients with PUBS decreased over subsequent decades. This necessitates the advancement of antibiotics and application of early goal-directed therapy. Additionally, the overall mortality rate of PUBS (1980-2016) was 6.8%, which decreased to 4.3% in the last 5 years (2011-2016). In conclusion, although PUBS has previously been considered a benign process in the majority of indwelling catheterized patients, emphasis is required on early examination and aggressive antibiotic administration.

Trauma in the elderly population is frequent and is associated with significant mortality, owing not only to age-related factors, but also those complicated factors relating to lack of physical reserves, the injury severity, preexisting comorbidity, and insufficient ability for systemic compensation. Age-related mortality remains constant in the low to moderately severe injury categories compared with the severely injured groups (injury severity score, ISS, 25 or greater). The age-related insufficient physical reserves for cardiac output leave this group in the state of hypoperfusion, which is hard to identify. The circumstances around metabolic demands and lower maximum heart rate with a higher peripheral vascular resistance make the cardiovascular system reserve unable to respond, which means that a diagnosis of shock is more difficult to establish. Higher ISSs obtained at injury in the elderly population can predict higher mortality better than in younger population, but they have not been as effective in predicting mortality obtained at follow-up of elderly trauma patients compared with those at the time at injury. More aggressive care for the elderly trauma patient has been shown to decrease mortality. Because of the multiple mortality factors, a decision on treatment type following trauma in geriatric patients is unable to be made if the clinician is not alert to the pitfalls which can affect these individuals. Regardless of age or injury severity and with special considerations for those patients who arrive in a moribund condition, geriatric trauma patients should be treated with as much effort as their younger counterparts, that is, aggressively and within a certain time frame.

Bongkrekic acid (BKA), a rarely happened foodborne toxin by Burkholderia gladioli pathovar cocovenenans (Burkholderia cocovenenans) might leads to devastating life-threatening condition after eating meal contaminated BKA. Unbelievable event from March 19, 2024, to March 24, 2024, there was an outbreak of BAP in a luxury shopping area of eastern Taipei, Taiwan. Most of the victims are young to middle-aged people who made a tour over there and ate the cooked wet rice noodles. Of them, 13 males and 20 females, aged 40.9 ± 14.7 years old visited or were sent by ambulances to the emergency department presenting with watery diarrhea, and vomiting. Some progressed to severe hepatic and renal failure, altered mental status, disseminated intravascular coagulation, and fatalities within several hours within 2 days. The primary health workers especially emergency physicians need to keep in mind of BKA poisoning is quite different in presentations from other infectious colitis commonly seen before. Knowing the toxic-kinetic and toxic-dynamic mechanisms is important to farseeing the presentation of these BAP patients. Throughout this outbreak, we gathered abundant experiences in mitigating and managing these debilitated patients. Aggressively supportive care and early liver transplantation if there is no concurrent inflammatory process and the patient's condition is tolerable to surgical intervention saves lives. For food safety education, it is crucial to enhance our understanding of inhibiting BKA production and promote proper food preservation methods and a suitable environment to ensure food safety.
