Analysis of traumatic intracranial hemorrhage and delayed traumatic intracranial hemorrhage in patients with isolated head injury on anticoagulation and antiplatelet therapy.

Objectives: Anticoagulants and antiplatelet (ACAP) agents are increasingly and frequently used, especially in the elderly. The present study was carried out to assess the prevalence of delayed traumatic intracranial hemorrhage (dtICH) after a normal result on an initial head computed tomography (CT) in adults who were taking ACAP medication. Materials and Methods: The present retrospective included all adult patients who arrived in the emergency department between January 2017 and January 2021 with a history of fall from the patient's own height, while being on ACAP medication with an isolated head injury. The Institutional Review Board approved the study with a waiver of consent. The primary outcome measures were prevalence of dtICH in patients who had initial normal CT scan brain and were on ACAP medication. Results: There were 2137 patients on ACAP medication, of which 1062 were male, and 1075 were of the female gender. The mean age of the patients was 82.1 years. About 8.2% had positive first CT scans (176/2137), while 0.023 (27/1149) had dtICH. The most common positive finding on the CT scan was subarachnoid hemorrhage followed by subdural hemorrhage. Male gender positively correlated with increased risk for first CT being positive (P = 0.033). Patient's with comorbidity of cirrhosis and chemotherapy had higher risk of dtICH (P = 0.47, 0.011). Conclusion: There was a very low (0.023%) prevalence of dtICH. Dual therapy or Coumadin therapy made up the majority of tICH. Cirrhosis and chemotherapy were associated with the risk of a repeat CT scan being positive with an initial CT scan negative.

Steroids use in non-oxygen requiring COVID-19 patients: a systematic review and meta-analysis.

BACKGROUND: Corticosteroids have become the mainstay treatment in severe COVID-19. However, its role is mild disease is controversial due to lack of robust scientific evidence. This systematic review and meta-analysis were conducted to assess effect of steroids in mild COVID-19 patients. METHODS: PubMed, EMBASE, Web of Science and medRxiv were searched from 31 December 2019 to 14 May 2021 for studies that reported effectiveness of steroids in non-oxygen requiring COVID-19 patients in terms of progressing to severe disease, mortality, duration of fever, duration of viral clearance and length of hospital stay (LOHS). Studies on inhalational steroids, case reports and reviews were excluded. Risk of bias (ROB) was assessed by the Cochrane's ROB tool and ROBANS tool. Quantitative data synthesis was done using the generic inverse variance method. RESULTS: A total of 6411 studies were identified, 2990 articles were screened after exclusion. Seven studies which fit the criteria (involving 2214 non-oxygen requiring COVID-19 patients) were included and analysed. Overall odds of progression to severe disease among the non-oxygen requiring COVID-19 patients receiving steroids was 5.97 [95% confidence interval (CI): 1.27-27.99, I2 = 0%] and odds of death (OR: 1.35, 95% CI: 1.01-1.79; I2 = 0%) as compared to the patients not receiving steroids. Mean duration of fever (7.4 days), duration to viral clearance (18.9 days) and LOHS (20.8 days) were significantly higher in the steroid arm, as compared to that in no-steroid arm (6.7, 16.5 and 15.2 days, respectively). CONCLUSION: Steroids in non-oxygen requiring COVID-19 patients can be more detrimental than beneficial. PROTOCOL REGISTRATION: The study was prospectively registered in PROSPERO (CRD 42021254951).

Current Status of Indications, Timing, Management, Complications, and Outcomes of Tracheostomy in Traumatic Brain Injury Patients.

Tracheostomy is the commonest bedside surgical procedure performed on patients needing mechanical ventilation with traumatic brain injury (TBI). The researchers made an effort to organize a narrative review of the indications, timing, management, complications, and outcomes of tracheostomy in relation to neuronal and brain-injured patients following TBI. The study observations were collated from the published literature, namely original articles, book chapters, case series, randomized studies, systematic reviews, and review articles. Information sorting was restricted to tracheostomy and its association with TBI. Care was taken to review the correlation of tracheostomy with clinical correlates including indications, scheduling, interventions, prognosis, and complications of the patients suffering from mild, moderate and severe TBIs using Glasgow Coma Scale, Glasgow Outcome Scale, intraclass correlation coefficient, and other internationally acclaimed outcome scales. Tracheostomy is needed to overcome airway obstruction, prolonged respiratory failure and as indispensable component of mechanical ventilation due to diverse reasons in intensive care unit. Researchers are divided over early tracheostomy or late tracheostomy from days to weeks. The conventional classic surgical technique of tracheostomy has been superseded by percutaneous techniques by being less invasive with lesser complications, classified into early and late complications that may be life threatening. Additional studies have to be conducted to validate and streamline varied observations to frame evidence-based practice for successful weaning and decannulation. Tracheostomy is a safer option in critically ill TBI patients for which a universally accepted protocol for tracheostomy is needed that can help to optimize indications and outcomes.

Cholera in ecuador: current relevance of past lessons learnt.

This report analyses the trends in the cholera epidemic that hit Ecuador in 1991. The study is based on personal experiences and analysis of epidemiological databases from the Ministry of Public Health of Ecuador. The number of cases and initial attack rates in an immunologically naive population are described by province. An analysis of the Andean and coastal cholera patterns of transmission are described along with its associated risk factors. The logistical, environmental, and socio-cultural risk factors prevalent during the epidemic and the control measures implemented are also reviewed. Also, the role of the epidemic in the development of the public health and healthcare resources in Ecuador is discussed here. Current data indicate favorable conditions for another outbreak of cholera in Ecuador. In view of the existing risk factors, new strategies are proposed to prevent such an epidemic in the future.

Clinical and epidemiological implications of meningococcal disease.

Meningococcal disease is caused by Neisseria meningitidis and is an infection which rapidly progresses to multiorgan failure. It was a major killer in the epidemics of the 1980's in the United States. With the advent of Haemophilus influenzae type b (Hib) vaccine in the 1990s, Streptococcus pneumoniae and Neisseria meningitidis have become the most common causes of bacterial meningitis in the United States. This article provides a review of the meningococcal illness and attempts to update current information regarding the same.

Hepatic sarcoidosis responding to chloroquine as steroid-sparing drug.

We report a 59-year-old lady who presented with exertional dyspnea and was diagnosed to have sarcoidosis. She responded to steroids, but one year later developed abdominal symptoms and was found to have hepatosplenomegaly. Liver biopsy showed non caseating granulomas. As she had developed steroid-induced diabetes she was started on chloroquine and responded well with regression of the liver and spleen during one year of treatment.
