RESUMEN
Waterhouse-Friderichsen syndrome is a rare but potentially fatal disorder of the adrenal gland characterized by bilateral adrenal hemorrhage. It is classically a result of meningococcal sepsis and presents acutely with features of shock, petechial rashes, abdominal pain, and non-specific symptoms such as headache, fatigue, and vomiting. Treatment consists of fluid resuscitation, corticosteroid replacement, and possibly surgery. The prognosis is poor despite treatment. This chapter will review the etiology, pathogenesis, clinical features, and management of the disease.

Aims: This study entails an association between bronchial asthma and common single nucleotide polymorphisms (SNPs) in thymic stromal lymphopoietin (TSLP) gene; rs2289278, rs3806933, rs2289276, and rs1837253. Methods: The databases of PubMed, Embase, Web of Science, and Google Scholar were searched for studies reporting TSLP polymorphisms and asthma from inception to January 2022. Hardy-Weinberg equilibriums (HWE) for each polymorphism of the control group were checked using the χ 2 test. The association was estimated by means of odds ratio (OR) with 95% CI in both dominant and recessive modes of inheritance, respectively. Results: Altogether, 11 studies with 3121 asthma cases and 3041 healthy controls were added. Results from six studies showed that the SNP rs2289278 had a protective role in asthma development (OR=0.65, 95% CI: 0.44-0.97, P=0.04). Pooling of four studies showed that the SNP rs3806933 had higher odds of developing asthma (OR=1.32, 95% CI:1.14-1.54, P<0.01). However, the SNP rs2289276 and rs1837253 showed no significant association. From the subgroup analysis, SNPs rs2289278 and rs1837253 were protective against the development of asthma in Asia. However, SNP rs2289276 showed a risk association in Asia and in adults. Conclusion: This meta-analysis shows that the SNP rs2289278 has a protective effect on the development of asthma; whereas rs3806933 has a risk of asthma. Additionally, this study adds genomic-based support to the recent FDA approval of tezepelumab, an anti-TSLP agent.
RESUMEN
Background: Bilothorax is defined as the presence of bile in the pleural space. It is a rare condition, and diagnosis is confirmed with a pleural fluid-to-serum bilirubin ratio of >1. Methods: The PubMed, Embase, Google Scholar, and CINAHL databases were searched using predetermined Boolean parameters. The systematic literature review was done per PRISMA guidelines. Retrospective studies, case series, case reports, and conference abstracts were included. The patients with reported pleural fluid analyses were pooled for fluid parameter data analysis. Results: Of 838 articles identified through the inclusion criteria and removing 105 duplicates, 732 articles were screened with abstracts, and 285 were screened for full article review. After this, 123 studies qualified for further detailed review, and of these, 115 were pooled for data analysis. The mean pleural fluid and serum bilirubin levels were 72 mg/dL and 61 mg/dL, respectively, with a mean pleural fluid-to-serum bilirubin ratio of 3.47. In most cases, the bilothorax was reported as a subacute or remote complication of hepatobiliary surgery or procedure, and traumatic injury to the chest or abdomen was the second most common cause. Tube thoracostomy was the main treatment modality (73.83%), followed by serial thoracentesis. Fifty-two patients (51.30%) had associated bronchopleural fistulas. The mortality was considerable, with 18/115 (15.65%) reported death. Most of the patients with mortality had advanced hepatobiliary cancer and were noted to die of complications not related to bilothorax. Conclusion: Bilothorax should be suspected in patients presenting with pleural effusion following surgical manipulation of hepatobiliary structures or a traumatic injury to the chest. This review is registered with CRD42023438426.

BACKGROUND: Tuberculosis (TB) is a serious public health concern around the world including Asia. TB burden is high in Asian countries and significant population harbor latent tuberculosis infection(LTBI). AIM: This systematic review and meta-analysis aims to evaluate the prevalence of LTBI in Asian countries. METHOD: We performed a systematic literature search on PubMed, Embase, and ScienceDirect to identify relevant articles published between January 1, 2005, and January 1, 2023 investigating the overall prevalence of latent TB among people of Asia. Subgroup analysis was done for Asian subregions during the study period of 2011 to 2016 and 2017 to 2023, for tuberculin skin test (TST) and interferon gamma release assay (IGRA), respectively, as well as for QuantiFERON-TB (QFT) and TSPOT TB tests. Der Simonian and Laird's random-effects model was used to pool the prevalence of LTBI found using TST and IGRA. RESULT: A total of 15 studies were included after a systematic search from standard electronic databases. The analysis showed that the prevalence of latent TB in Asia was 21% (95% confidence interval [CI]: 19%-23%) and 36% (95% CI: 12%-59%) according to IGRAs and TSTs (cut off 10 mm) results, respectively. Based on IGRA, the prevalence of latent TB was 20% (95% CI: 13%-25%) in 2011 to 2016 and 21% (95% CI: 18%-24%) in 2017 to 2023. Using QFT, the prevalence was 19% (95% CI: 17%-22%) and using TSPOT, the prevalence was 26% (95% CI: 21%-31%). According to the United Nations division of Asia, the prevalence was higher for the Southern region and least for the Western region using TST and higher in the South-Eastern region and least in the Western region using the IGRA test. CONCLUSION: Almost a quarter of the Asian population has LTBI. Its diagnosis often poses a diagnostic challenge due to the unavailability of standard test in certain areas. Given this prevalence, a mass screening program is suggested with the available standard test and public awareness along with anti-TB regimen should be considered for individuals who test positive. However, for it to be implemented effectively, we need to take the affordability, availability, and cost-effectiveness of such interventions into account.
