RESUMEN
OBJECTIVE: To assess gender bias, discrimination and bullying at medical schools, and to explore the phenomenon of 'doctor brides'. METHODS: The multicentre survey was conducted at 14 medical education institutions across Pakistan from September 2020 to April 2021, and comprised medical students of either gender at both public-sector and private-sector institutions. The survey questions explored beliefs, experiences and knowledge related to common stereotypes and social issues in medical education, including female role models, work-life balance, gender roles, lack of support from family and faculty, and bullying. Association between gender with survey variables was explored. Data was analysed using SPSS 26. Thematic analysis was used to exploring knowledge around 'doctor-brides'. RESULTS: Of the 377 subjects, 245(65%) were females. The overall mean age was 21.4±1.8 years. There were 211(53.8%) subjects aged 21-23 years, and 368(97.6%) were Muslims. Significantly more women than men were of the opinion that men are encouraged and are more likely to assume leadership roles (p=0.002). More women than males agreed that household chores and work had an impact on speciality choice (p<0.001). Most sexual assault victims were women (p<0.0001), but men generally faced more bullying and hostile behaviour (p=0.014). With regard to women being forced to quit medicine after marriage/childbirth by their in-laws/husbands or change their careers from clinical medicine to preclinical teaching, 99(26.25%) subjects knew first-hand of such cases, while 238(63.12%) had no such experience to share. CONCLUSIONS: Gender bias, discriminatory behaviour and bullying were found to be widely prevalent in medical schools across Pakistan. The general perception of 'doctor brides' needs to be revisited.

Benvitimod is a topical drug that has recently been approved for mild to moderate psoriasis and atopic dermatitis. The drug has just completed phase 3 trials for psoriasis, which calls for a systematic update of current evidence on the efficacy and safety of this drug. We searched MEDLINE (PubMed), EMBASE, Science Direct, International Clinical Trials Registry Platform (ICTRP), Cochrane Central Register of Controlled Trials, and Google Scholar for all available randomized controlled trials concerning the topic. We included six randomized controlled trials evaluating the efficacy of benvitimod 1.0% with a total of 1925 patients. Our meta-analysis demonstrated that more patients in the benvitimod group achieved physician global assessment score of 0 or 1 (RR 6.53, 95% CI 4.39-9.71), psoriasis area and severity index (PASI) 75 (RR 4.34, 95% CI 2.96-6.36), PASI 90 (RR 8.83, 95% CI 5.22-14.95) and body surface area reduction (MD -3.85, 95% CI -4.83, -2.88) than placebo at week 12. Patient-reported outcomes were also analyzed, yielding a significant benefit in the benvitimod group for peak pruritus numerical rating scale (PP-NRS) score (MD -1.20, 95% CI -1.98, -0.42), ≥4-point decrease in PP-NRS score (RR 1.58, 95% CI, 1.24-2.03) and dermatology life quality index score (MD -2.54, 95% CI -4.00, -1.07). There was a significantly higher incidence of adverse events in the benvitimod group compared to placebo (RR 1.98, 95% CI 1.73-2.27), while the risk was found to be non-significant for serious adverse events. Benvitimod is an effective treatment of psoriasis as compared to a placebo. However, more large-scale, high-quality trials are needed to comment on the safety of this drug.

BACKGROUND: Guillain-Barré syndrome (GBS) is a heterogeneous disease characterized by rapidly progressive, symmetrical limb weakness with hyporeflexia or areflexia. The rare pharyngeal-cervical-brachial (PCB) variant of GBS occurs in 3% of patients, presenting as rapidly progressive oropharyngeal and cervicobrachial weakness characterised by axonal, rather than a demyelinating neuropathy on nerve conduction studies. CASE DESCRIPTION: A 35 year old male presented with a 5-day history of dysphagia, dysarthria, slurred speech and upper limb weakness. Physical examination showed bilateral facial nerve weakness and an impaired gag reflex. Nerve conduction study was suggestive of sensory and motor polyneuropathy of predominantly demyelinating variety. As the condition of the patient worsened, respiratory support was required and plasmapharesis was started. There was significant improvement in his condition after completion of 5 sessions of plasmapharesis. CONCLUSION: The rare PCB variant may present with a predominantly demyelinating neuropathy. Early clinical recognition of this variant and prompt treatment with plasmapharesis is essential for preventing respiratory complications.
RESUMEN
Objective: COVID-19, a respiratory infection caused by the novel coronavirus SARS-CoV-2, can cause varying degrees of illness ranging from mild respiratory illness to severe respiratory failure. Systemic sclerosis is a chronic autoimmune disease, with an increased prevalence of infections as compared to the general population. In this study, we compare the clinical outcomes and resource utilization for COVID-19 hospitalizations in patients with and without systemic sclerosis. Methods: We used the National Inpatient Sample database, 2020, to study the characteristics, morbidity, mortality, cost, and resource utilization among primary COVID-19 hospitalizations with and without systemic sclerosis. Results: There were 1,050,040 patients aged ⩾ 18 years with a diagnosis of COVID-19. Of these, 775 (0.07%) patients had a secondary diagnosis of systemic sclerosis. Although there was no statistically significant difference regarding individual outcomes; in-hospital mortality, vasopressor use, cardiac arrest, acute kidney injury, and disposition to facility were numerically higher in hospitalizations with systemic sclerosis. The composite endpoint of major adverse events was higher in the systemic sclerosis cohort (adjusted odds ratio 1.52, 95% confidence interval: 1.06-2.17, p = 0.022). Conclusion: COVID-19 patients with systemic sclerosis had worse outcomes (i.e. higher composite endpoint of major adverse events) than those without systemic sclerosis. Further studies are needed to establish a better understanding of the relationship between COVID-19 and systemic sclerosis.
RESUMEN
OBJECTIVES: The exact etiology of Parsonage-Turner syndrome is unknown, but it is known to be preceded by infection, vaccination, or surgical intervention. In this review, we describe associations of Parsonage-Turner syndrome with COVID-19 infection and vaccination. METHODS: A systematic literature search was conducted using PubMed/MEDLINE, ScienceDirect, and Google Scholar. Microsoft Excel was used for data extraction and statistical analysis. The quality of case reports and case series was assessed using the Joanna Briggs Institute Critical Appraisal Tool. RESULTS: We selected 44 case reports and 10 case series, including 68 patients (32 post-vaccination and 36 with post-COVID-19 infection Parsonage-Turner syndrome). Middle-aged males were predominantly affected in both groups. The most frequently administered vaccine was Comirnaty (Pfizer) (53%). The mean latency was 11.7 days in the post-vaccination group and 20.3 days in the post-infection group. The most affected nerves in both groups were the axillary, suprascapular, and musculocutaneous nerves; and 78.1% and 38.9% of patients showed partial amelioration of their symptoms in the post-vaccination and post-infection groups, respectively. CONCLUSION: Post-vaccination Parsonage-Turner syndrome presents earlier than post-infection disease. Pain and sensorimotor deficits of the upper limb are common in both situations. Complete or partial recovery occurs in most cases.

Brain metastasis in gastric cancer (GC) patients is a rare phenomenon that is associated with adverse clinical outcomes and poor survival rates. We conducted a retrospective cohort study to investigate the incidence, risk factors and prognostic factors of brain metastasis in GC patients. Data on sociodemographic and tumor characteristics of GC patients from 2010 to 2019 was extracted from the Surveillance, Epidemiology and End-Results (SEER) database. Descriptive statistics, multivariable logistic and Cox regression were applied on SPSS. Kaplan-Meier-Survival curves and ROC curves were constructed. A total of 59,231 GC patients, aged 66.65 ± 13.410 years were included. Brain metastasis was reported in 368 (0.62%) patients. On logistic regression, the risk of brain metastasis was significantly greater in males, patients aged < 60 years and patients having concurrent bone and lung metastasis. High grade and high N stage were significant risk factors for development of brain metastasis. Patients who had undergone surgery for the primary tumor were at reduced risk for brain metastasis (adjusted odds ratio 0.210, 95% CI 0.131-0.337). The median OS was 3 months in patients with brain metastasis and 17 months in patients without brain metastasis (p < 0.05). On Cox regression, Grade IV tumors and primary antral tumors were significant predictable parameters for poor prognosis. Overall Survival (OS) and Cancer-Specific Survival (CSS) were prolonged in patients who had undergone surgery. Brain metastasis in gastric cancer is associated with significantly worse survival. Employing large-scale screening for high-risk patients holds a promising impact to improve survival rates, but it must be accurately balanced with a comprehensive understanding of clinicopathological aspects for accurate diagnosis and treatment.

Purpose: A popular genre of television shows is medical dramas. Although the primary objective of watching these shows is entertainment, acquiring medical knowledge is a passive by-product. Surgical procedures constitute a large part of the storyline of these shows. This could either serve as a source of medical knowledge or provide false information, the effect being especially important in individuals with no prior medical exposure. This study assesses the impact medical TV shows can have on the surgical knowledge of non-healthcare students and the difference in knowledge between different demographic groups (among those with relatives in the medical community and those without). Methods: A cross-sectional study was conducted among the non-healthcare students of Lahore, Pakistan. A self-administered questionnaire was used containing socio-demographic factors (age, gender, educational discipline), history, and hours of medical TV shows watched. It also contained ten questions each with a score of 1 to assess surgical knowledge. Data were analyzed using SPSS v.26. Results: Among the 1097 respondents, 450 (41%) had a history of watching medical TV shows. The majority, 319 (29.1%), had seen these shows for < 24 hours. The mean score of all respondents was 5.79 out of a maximum score of 10. Respondents with a history of watching medical TV shows were more knowledgeable than those who did not (p < 0.001). Similarly, respondents with a history of watching more hours of medical TV shows were more knowledgeable than those who watched for a lesser number of hours (p < 0.001). Respondents with relatives in the healthcare profession were also more knowledgeable than those without (p = 0.049). Conclusion: If properly developed, while maintaining their primary entertainment value, medical TV shows can also be used as efficient learning tools. Quality controls must also be applied to minimize the risk of false information.
RESUMEN
BACKGROUND: Presently, there is conflicting evidence regarding the efficacy of probiotics in the prevention of ventilator-associated pneumonia (VAP). This meta-analysis was conducted to update current clinical evidence and evaluate the efficacy and safety of probiotics for the prevention of VAP. METHODS: We searched three databases and two trial registers to retrieve randomised controlled trials (RCTs) comparing probiotics or synbiotics with placebo or standard treatment for the prevention of VAP in adult patients receiving mechanical ventilation in the intensive care unit (ICU). RESULTS: Our meta-analysis included 18 RCTs involving 4893 patients. Our results showed that probiotics may reduce the incidence of VAP (RR 0.68, 95% CI: 0.55-0.84; low certainty). However, in our subgroup and sensitivity analyses, the effect was not significant in double-blind studies, and in studies with a low risk of bias in the randomisation process. Probiotics reduced the length of ICU stay (MD -2.22 days, 95% CI: -4.17 to -0.28; moderate certainty) and the duration of antibiotic use (MD -1.25 days, 95% CI -1.86 to -0.64; moderate certainty). CONCLUSIONS: Probiotics may reduce the incidence of VAP but due to the low quality of pooled evidence, the use of probiotics warrants caution. Further, large-scale, high-quality RCTs need to be conducted to provide conclusive evidence.

BACKGROUND: As part of the 'small round-cell tumor' family, Ewing's sarcoma (ES) is a malignant mesenchymal tumor classified as a primitive neuroectodermal tumor (PNET). Within the PNETs, spinal extraosseous extradural lesions are exceedingly rare. CASE DESCRIPTION: A 19-year-old male presented with a one-month history of back pain and paraparesis with loss of urinary control. The MRI revealed an intradural, extramedullary mass at the T3-T4 level. Intraoperatively, the tumor was solely extradural, without evidence of local invasion; it was entirely removed. Due to the high risk of metastasis, the patient was subsequently treated with chemotherapy and radiation. In addition, similar studies on PNETs were reviewed. CONCLUSION: A 19-year-old male presented with a paraparesis attributed to an extraosseous extradural ES at the T3-T4 level. Following total gross resection, he was successfully managed with chemotherapy and radiation. The patient has been in remission for one month.
