Included were 239 participants (N=239) who had 18 19 20 been diagnosed with PTSD according to the DSM-5 and the PTSD Checklist - Civilian Version 21 22 (PCL) in 2006; participants were present for the 10-year follow up. 23 24 25 Main Outcome Measures: The PTSD prevalence rates of participants in 2006 and 2016 were 26 27 compared. The analysis of the demographical data pertained to the association of long-term PTSD 28 29 with other variables was performed. P-values <0.05 were considered statistically significant for 30 31 all analyses (95% CI). 32 33 34 http://bmjopen.bmj.com/ 35 Results: All the 244 civilians injured by cluster munitions in 2006 responded, and were present 36 37 for long-term follow up in 2016. The prevalence of PTSD decreased significantly from 98% to 38 39 43% after ten years (p<0.001). A lower long-term prevalence was significantly associated with 40 41 the male sex (p<0.001), family support (p<0.001), and religion (p<0.001). Hospitalization 42 on September 27, 2021 by guest.

However, often, when 26 27 they have been used near populated areas, civilians have died or got injured, either as a direct 28 29 result of the attack and its area effect, or as a result of post-conflict unexploded sub-munitions. 30 31 While all types of ordnances fail to function at some rate, the failure rate for cluster munitions is 32 33 striking. http://bmjopen.bmj.com/ 34 35 36 Due to their easily "pickable" nature, sub-munitions can inflict various injuries.

It was initially thought to spare children and adolescents as significantly smaller number of cases have been reported in the pediatric population in comparison to adults. Here, we report the case of a 16-month-old female infant from Lebanon who presented with fever and severe diarrhea and tested positive for COVID-19. Her symptoms started six days prior to presentation with no cough, rhinorrhea, or other respiratory manifestations reported. Chest radiography showed lobar consolidation and bronchial infiltrates. Blood culture was positive for Streptococcus pneumoniae. Stool and urine cultures were negative. She was treated with ceftriaxone and metronidazole. Her RT-PCR test was negative after five days of treatment, suggesting that children can clear the virus faster than adults. The patient likely contracted the virus from her parents, who because of the fear of social stigma hide recent history of respiratory illness. These findings serve as a practical reference for the clinical diagnosis and medical treatment of children with COVID-19.

Inflammatory markers such as pro-inflammatory cytokines are well-known etiological contributors for psychiatric disorders, including schizophrenia. Although, the role of inflammation in schizophrenia is becoming evident, the number of studies in this area is relatively scarce, especially in Lebanon, and increased procedural thoroughness is needed. Cytokines play a key role in the activation of the immune system and strongly influence neurotransmission. Previous investigation of plasma levels showed dysregulation of interleukin (IL)-12.

  • Coping Ability to Stress Among Allied Health Sciences Students
    Madhumitha & Archana (2020): Ability to cope to stress Dec, 2020 Vol. 23 Issue 23 Coping ability to stress among Allied Health Sciences Students 1 2 Madhumitha B , R. Archana* 1MBBS Student, Saveetha Medical College, Saveetha Institute of Medical and Technical Sciences, Chennai-602105, India 2Professor, Department of Physiology, Saveetha Medical College, Saveetha Institute of Medical and Technical Sciences, Chennai-602105, India *Corresponding author: [email protected] ( Dr Archana) ABSTRACT The vast medical syllabus along with patient interactions, clinical rotations and examinations can cause high levels of stress and anxiety among the medical students. Resilience is the coping ability to stress. Individuals who are more resilient are considered to be able to face stress and adversities with greater ease and thus produce better results academically. They function more optimally than less resilient individuals when faced with external stressors. Therefore, the objective of the study was to assess the resilience of physiotherapy and nursing students in order to understand their ability to handle stressors in life. A cross sectional study to assess resilience using a standard resilience questionnaire was conducted among the first year Physiotherapy and Nursing students of 18-25 years of age after obtaining informed consent and Institutional ethical clearance. All willing students fulfilling the inclusion and exclusion criteria were included in the study. The percentage of students having high, moderate and low resilience was assessed among the physiotherapy and nursing students. Among the 150 Nursing students and 141 Physiotherapy student participants, majority of the students had moderate resilience while only a significantly small percentage of students had high resilience score.

Protective measures, such as social distancing and face masks, are essential to mitigate efforts against the virus, but pose challenges on daily face-to-face communication. Face masks, particularly, muffle sounds and cover facial expressions that ease comprehension during live communication. Here, we explore the role of facial expressions in communication and we highlight how the face mask can hinder interpersonal connection. In addition, we offer coping strategies and skills that can ease communication with face masks as we navigate the current and any future pandemic.

We present a rare case of a Caucasian male, aged 26 years, who developed rhabdomyolysis-induced acute renal failure and uremic encephalopathy. Neurological examination and histopathological studies supported the diagnosis of McArdle disease. The severity of his symptoms necessitated urgent hemodialysis, upon which the patient reported improvement in status. Acute renal failure in McArdle disease usually resolves with supportive treatment and maintenance of regular physical activity. Nevertheless, in more severe cases, intensive care with urgent hemodialysis may be needed. A multidisciplinary approach is necessary for the adequate management of similar cases.
