Predictors of clinical outcomes in patients with sepsis: A retrospective study from a tertiary care hospital in Pakistan.

OBJECTIVE: To assess associations between various clinic-demographic factors and clinical outcomes among patients treated for sepsis. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of all patients aged >18 years diagnosed with sepsis from January to December 2019. Multivariable logistic regression was used to evaluate independent associations between predictors and outcomes. Data was analysed using R packages. RESULTS: Of the 1,136 patients, 621(54.6%) were male and 515(45.3%) were female. The overall mean age was 59.05±16.91 years. Female gender (odds ratio: 1.029; 95% confidence interval: 1.03-1.64) was found to be an independent predictor of septic shock, while hypertension (odds ratio0.75; 95% confidence interval: 0.59-0.95) emerged as a protective factor. Chronic kidney disease (odds ratio: 1.539; 95% confidence interval: 1.14-2.07) was an independent predictor of prolonged length of stay, while older age appeared to be protective (odds ratio: 0.98; 95% confidence interval: 0.98-0.99). Mortality was associated with a significantly lower odds of Escherichia coli on culture (odds ratio: 0.26; 95% confidence interval: 0.12-0.54). CONCLUSIONS: Independent associations were found between specific patient characteristics and adverse clinical outcomes.

Proposed novel classification of circumscribed Lower-Grade Gliomas (cLGG) vs. infiltrating Lower-Grade Gliomas (iLGG): Correlations of radiological features and clinical outcomes.

Purpose: We hypothesize that lower grade gliomas (LGG) can be identified and classified into two distinct subtypes: radiologically circumscribed Lower-Grade Gliomas (cLGG) and infiltrating Lower-Grade Gliomas (iLGG) based on radiological parameters and that these two different subtypes behave differently in terms of clinical outcomes. Methods: We conducted a retrospective cohort study on surgical patients diagnosed with lower grade glioma over five years. Patient records and MRIs were reviewed, and neurosurgeons classified tumors into cLGG and iLGG groups. Results: From the 165 patients in our cohort, 30 (18.2%) patients were classified as cLGG and 135 (81.8%) patients were classified as iLGG Mean age in cLGG was 31.4 years while mean age in iLGG was 37.9 years (p = 0.004). There was significant difference in mean blood loss between cLGG and iLGG groups (270 and 411 ml respectively, p = 0.020). cLGG had a significantly higher proportion of grade II tumors (p < 0.001). The overall mean survival time for the iLGG group was 14.96 ± 1.23 months, and 18.77 ± 2.72 months for the cLGG group. In univariate cox regression, the survival difference between LGG groups was not significant (HR = 0.888, p = 0.581), however on multivariate regression cLGG showed a significant (aHZ = 0.443, p = 0.015) positive correlation with survival. Intense contrast enhancement (HZ = 41.468, p = 0.018), blood loss (HZ = 1.002, p = 0.049), and moderately high Ki-67 (HZ = 4.589, p = 0.032) were also significant on univariate analyses.Conclusion: cLGG and iLGG are radiologically distinct groups with separate prognoses, surgical experience, and associations.

COVID-19 pandemic impacted internet use and anxiety among general public during COVID-19 pandemic in Pakistan.

Objective: To determine the association between internet use and anxiety among people during the coronavirus disease- 2019 pandemic. METHODS: The cross-sectional study was conducted across Pakistan from January 14 to February 21, 2021, which was the active phase of the coronavirus disease-2019 pandemic in Pakistan. The participants were aged at least 13 years having internet access regardless of gender or their location across Pakistan. The anonymous web-based survey was conducted using a questionnaire generated on Google Forms and disseminated through various social media platforms and WhatsApp groups. Anxiety symptoms were screened using the Depression, Anxiety and Stress Scale-21, while the Young Internet Addiction Test was used to evaluate symptoms of internet addiction. Data was analysed using STATA 16. RESULTS: Of the 1,145 subjects, 686(60%) were females and 459(40%) were males. A total of 257(22.5%) participants were found to have extremely severe anxiety and internet usage pattern was significantly associated with the level of anxiety (p<0.05). Age, gender, social class and marital status were not significantly different (p>0.05), while family income and area of living were significantly different (p<0.05) in terms of anxiety levels. The odd of addictive internet use was 10.2 (95% confidence interval: 5.7-18.5) times greater in extreme anxiety individuals compared to individuals having no anxiety after controlling for other sociodemographic, health-related, behavioural and environmental factors during the pandemic. Conclusion: A significant association of anxiety was found with internet addiction during the coronavirus disease-2019 pandemic.

Paediatric choroid plexus carcinoma: a retrospective case series from Karachi.

The objective of this study is to report clinical, radiological, and histopathological characteristics of three paediatric patients diagnosed as Choroid plexus carcinoma seen at our hospital, between 2015 and 2020. Three patients were diagnosed with choroid plexus carcinomas between 2015 and 2018. The mean age at diagnosis was 1.3 years (range 8 months to 1.5 years). All the three patients had subtotal resection and received adjuvant chemotherapy. One patient also received adjuvant radiotherapy. Despite these treatment measures, residual disease was noted in all three patients and two patients were subsequently treated on palliative care grounds. The average duration of follow-up after the first surgery for all three patients was approximately 33 months. Attaining satisfactory outcome in patients with CPC is challenging. Our case series reflects the difficulty in achieving gross total resection and ensuring that the disease does not recur.

Potassium Channel Subfamily T Member 1(KCNT1) Pathological Variant Causing Epilepsy Of Infancy With Migrating Focal Seizures: A Case Report.

Pathological mutation of potassium channel subfamily T member 1 (KCNT1) gene causes an autosomal dominant disorder characterised by secondarily generalised seizures/migratory focal seizure, cyanosis, and dysmorphic features. We report the case of a five-month old male with pathological KCNT1 variant who presented with focal clonic seizures, Mongol spots, and grade two systolic murmur at the left lower sternal border and loud P2. The seizures were refractory to most anti-epileptic drugs but showed some response to Valproic acid. This case demonstrated that EIMFS is a grave infantile epileptic encephalopathy which is refractory to anti epileptic drugs and can present with a wide spectrum of neurogenic and cardiogenic symptoms.

Early Infantile Epileptic Encephalopathy In Asparagine-Linked Glycosylation Thirteen (ALG13) Gene Defect And Dramatic Response With Ketogenic Diet.

Asparagine-linked glycosylation thirteen (ALG13) gene-related congenital disorders of glycosylation (CDGs) include early onset epileptic encephalopathy (EIEE), developmental delays (DD) with intellectual disability (ID), speech and visual abnormalities, and haematologic and endocrine dysfunctions. Worldwide there is a scarcity of available data on this. To add to this scarce data, we report the case of a young girl with this rare genetic mutation who showed remarkable improvement in her seizures by addition of ketogenic diet (KD) to her management regimen. With an already high rate of consanguineous marriages, metabolic and genetic errors are widely prevalent; hence, to bridge the huge gap in the understanding of such diseases, further research and trials are needed to be carried out to improve identification of the disease along with outcomes.

The effect of preoperative steroids for at least 10 days on complications following craniotomy for tumor resection: A database, retrospective cohort study.

Introduction: The effect of chronic steroid therapy on postoperative outcomes after craniotomy for tumor resection remains understudied. Research question: This study aimed to fill this gap and to identify risk factors of postoperative morbidity and mortality among patients on chronic steroid use undergoing craniotomy for tumor resection. Materials and methods: Data from the American College of Surgeons National Surgical Quality Improvement Program were used. Patients who underwent craniotomy for tumor resection between 2011 and 2019 were included. Perioperative characteristics and complications were compared among patients with and without chronic steroid therapy, defined as steroid use for at least 10 days. Multivariable regression analyses were conducted to assess the impact of steroid therapy on postoperative outcomes. Subgroup analyses involving patients on steroid therapy were conducted to explore risk factors of postoperative morbidity and mortality. Results: Of 27,037 patients, 16.2% were on steroid therapy. On regression analyses, steroid use was significantly associated with any postoperative complication, infectious complication, urinary tract infection, septic shock, wound dehiscence, pneumonia, non-infectious, pulmonary, and thromboembolic complications, cardiac arrest, blood transfusion, unplanned reoperation, readmission, and mortality. On subgroup analysis, risk factors for postoperative morbidity and mortality among patients on steroid therapy included older age, higher American Society of Anesthesiology physical status, functional dependence, pulmonary and cardiovascular comorbidities, anemia, dirty/infected wounds, prolonged operative time, disseminated cancer, and a diagnosis of meningioma. Discussion and conclusion: Preoperative brain tumor patients on steroids for 10 or more days are at a relatively high risk of postoperative complications. We recommend a judicious use of steroids in brain tumor patients, both in terms of dosage and duration of treatment.

Utility of neutrophil to lymphocyte ratio to predict acute respiratory distress syndrome in COVID-19: short communication.

Acute respiratory distress syndrome (ARDS) is the most severe and devastating form of acute lung injury. Neutrophil to lymphocyte ratio (NLR) and C-reactive protein have been used to predict severity and prognosis of certain viral illnesses. Methods: A retrospective cohort study was conducted in hospitalized COVID-19 patients. Serial measurements of NLR and C-reactive protein were recorded and patients were followed for development of ARDS. Results: Out of 388 patients admitted with COVID-19, 43 patients developed ARDS compared with 345 patients who did not develop ARDS. The median NLR at presentation was significantly higher in patients who developed ARDS (8.89 vs. 4.25) compared with those who did not develop ARDS (P<0.001). Moreover, serial measurement of NLR at presentation, day 3, day 5 and day 7 was significantly associated with development of ARDS (P<0.001). In multivariable analysis, age of greater than or equal to 50 years (adsjusted odds ratio=3.28; 95% CI=1.40-7.69) and unit increase in NLR at presentation (adsjusted odds ratio=1.07; 95% CI=1.03-1.11) were independently associated with development of ARDS. Conclusion: Serial measurement of NLR can predict patients who are at a greater risk for developing ARDS in COVID-19.

Surveillance of aetiologies, clinical presentation, and most common types of epilepsy among paediatric patients at a tertiary care hospital in Pakistan.

Epilepsy is the third most common neurological disease in the world associated with a high frequency in the paediatric age group. This study aims to evaluate the prevalence, types and aetiologies of epilepsy within the Pakistani population. A retrospective review of the charts of all patients, below the age of 18 years, presenting with epilepsy to the Department of Neurology at The Children's Hospital and Institute of Child Health, Lahore, from January 2016 to December 2020, was carried out. Analysis was performed using SPSS Version 26. A p value of <0.05 was considered statistically significant. A total of 1,097 patients were studied, of which 644 (58.8%) were males and 451 (41.2%) females. a vast majority, i.e. 1,021 (96.1%), of the study participants, belonged to the province of Punjab. Afebrile seizures [n=798 (72.7%)] were more commonly reported than febrile seizures [n=299 (27.3%)]. Among seizure types, generalised seizures were the most common type of seizure reported in 520 (49.8%) patients. Refractory seizures were the least common type reported in 3 (0.3%) patients. Aetiology was mostly idiopathic [n=540 (49.2)], followed by congenital [n=228 (20.8%)]. The most frequently reported duration of seizure was between one and three minutes [n=116 (42.3%)]. The most common ictal features seen were a combination of up-rolling of eyes and frothing from the mouth [n=206 (34.9%)]. Results from this study can be used by health care providers to better formulate therapeutic interventions for a timely diagnosis and effective treatment of epilepsy.

Hepatitis-associated aplastic anaemia: surveillance of frequency,clinico-haematological features, and demographic distribution at a tertiary care hospital in Pakistan.

OBJECTIVE: We aim to document the frequency of HAAA cases among AA patients presenting at a tertiary care hospital, and to determine the most common agents (viral/drug induced) and Clinico-haematological features among HAAA patients at a tertiary care hospital. Methods: This study was a retrospective review, conducted at a tertiary care hospital in Karachi, Pakistan. RESULTS: A total of 21 patients were included in the study. Hepatitis among the HAAA patients was viral in 17 cases, while 4 were idiopathic. All the patients acquired aplastic anaemia within 3-12 months of the Hepatitis episode and most presented with bleeding, bruises and petechiae. CONCLUSIONS: This study indicates and proves that presence and prevalence of this disease in the Pakistani population is quite significant. Unlike the rest of the world, HAAA in Pakistan is not entirely of unknown aetiology, most of the cases can be associated with one of the Hepatitis viruses.

Demographic and Psychosocial Factors associated with Internet Addiction among the Pakistani Population during COVID-19: A Web-Based Survey.

This study aims to determine the burden of COVID19-induced internet addiction and related psychosocial factors among the Pakistani sample. A web-based cross-sectional survey was conducted from January to March 2021. An analytical cross-sectional survey was broadcast on the internet via a Google form completed by 1145 Pakistanis. Individuals aged 13 years and above with competency to comprehend English or Urdu language, currently residing in any province of Pakistan, having access to the questionnaire, and willing to participate were eligible to participate. Overseas Pakistanis were excluded from the study. The outcome is COVID19-induced internet addiction was measured using the validated tool Young's Internet Addiction Test (IAT). In addition, symptoms of depression, anxiety, stress, and other psychosocial factors were assessed using the validated tool Depression, Anxiety, and Stress Scale-21 (DASS-21). Adjusted odds ratios with a 95% confidence interval were reported using multinomial logistic regression. Most participants were females and youth (between 20 and 24 years). The prevalence of problematic internet users (PIU) and addictive internet users (AIU) was 27.3% and 11.3%, respectively. The odds of extremely severe anxiety among AIU were approximately three times (Adj OR: 2.6 (1.1-7.1), followed by the odds of having extremely severe stress being about five times higher among AIU (Adj OR: 5.4 (1.6-17.6)) as compared to normal internet users (NIU). Amid COVID-19, the burden of internet addiction has surged among the Pakistani populace. This study identified that gender, marital status, depression, stress, anxiety, work situation, and mood changes during the COVID-19 pandemic are significantly correlated with problematic and addictive internet use. Preventative measures against the addictive use of the internet are needed to avoid or mitigate any serious mental health problems.

Surgical Outcomes of Endoscopic Endonasal Versus Transcranial Resections of Adult Craniopharyngioma: A Meta-Analysis.

BACKGROUND: The endoscopic endonasal approach (EEA) has been gaining popularity for resection of adult craniopharyngiomas. However, the safety and effectiveness of the procedure in comparison to the traditional transcranial approach (TCA) remains unestablished as previous reviews are outdated. METHODS: A literature search without language restriction was conducted in PubMed, Cochrane database, and Web of Science from conception to July 9, 2021. Cohort studies and case series that compared EEA with TCA and assessed postoperative complications, recurrence, and 30-day mortality were included. Articles, where data for adult populations could not be extracted or calculated, were excluded. Article selection and data extraction in a predesigned data extraction form were conducted in duplicate. Pooled participant data were included in a random-effects model. RESULTS: The search yielded 227 articles, from which eight cohort studies containing 11,395 patients were included (EEA: 6,614 patients, TCA: 4,781 patients). Six studies were good quality and two were fair quality according to the Newcastle Ottawa Scale. There were significantly higher rates of cerebrospinal fluid leak (risk ratio [RR]=0.23, 95% confidence interval [CI] 0.17-0.32, p<0.00001, I²=0%) and lower rates of postoperative hypopituitarism (RR=1.40, 95% CI 1.30-1.51, p<0.00001, I²=0%), hydrocephalus (RR=6.95, 95% CI 5.78-8.36, p<0.00001, I²=0%), visual impairment (RR=1.52, 95% CI 1.34-1.73, p<0.00001, I²=0%), and 30-day mortality (RR=5.63, 95% CI 3.87-8.19, p<0.00001, I²=0%) after EEA. Non-significant lower rates of postoperative diabetes insipidus (RR=1.12, 95% CI 0.78-1.61, p=0.53, I²=85%) and recurrence of tumor (RR=2.69, 95% CI 0.35-20.81, p=0.34, I²=47%) were seen after EEA. CONCLUSION: EEA may be associated with reduced postoperative hypopituitarism, hydrocephalus, visual impairment, and 30-day mortality and higher rates of cerebrospinal fluid leak. These findings do not account for differences in tumor size and extension between the EEA and TCA cohorts. Further research on patients with comparable tumor characteristics is required to fully assess outcomes.

AKU Giant Pituitary Adenoma Score: A Novel Scoring System to Predict the Outcomes of Surgery for Giant Pituitary Adenomas.

Background No scoring system is available to predict the extent of resection of giant pituitary adenomas (GPAs) based on magnetic resonance imaging (MRI) parameters. We developed a novel AKU Giant Pituitary Adenoma (AGPA) score and assessed the predictive ability of the scoring system concerning the extent of resection of GPAs. Methodology We retrospectively collected data of patients presenting with GPAs and used our scoring system to assess the surgical resection of these tumors. The Lundin-Pederson (ABC/2) method was used to calculate the pre- and post-resection tumor volume. The relationship between the extent of resection and the AGPA score was assessed using linear regression. The AGPA score considered the tumor's extension into various planes. The maximum total score was 9. Results The scoring system was applied to 45 patients with GPA who underwent surgical resection. The mean resected tumor volume (%) was 82.0 ± 16.7, and the overall mean AGPA score was 4.2 ± 0.8. The pairwise correlation between the resected tumor volume and the overall AGPA scores showed a strong inverse association (r = -0.633, p < 0.001). A significant difference was detected between the estimated scores of 3 and 5 and 4 and 5 (p < 0.001). Conclusions AGPA score is inversely related to the extent of the tumor to be resected, which would help surgeons predict the amount of tumor resection possible as well as predict the difficulty of surgery and plan optimal preoperative patient counseling. In addition, it can predict if staging and a transcranial approach are required.

Prognostic implication of size on outcomes of pituitary macroadenoma: a comparative analysis of giant adenoma with non-giant macroadenoma.

BACKGROUND: Due to the differences in size and invasiveness when compared to non-giant macroadenomas (nGPAs), giant pituitary adenomas (GPAs) are considerably harder to resect. This study aimed to differentiate GPAs from nGPAs, based on the presenting complaints, surgical approaches, peri- and postoperative outcomes. METHODS: We retrospectively analyzed cases of pituitary macroadenomas that underwent surgical resection at a tertiary care hospital. GPAs were tumors greater than 4 cm in the largest dimension, while nGPAs were tumors smaller than 4 cm. 55 GPA patients and 70 nGPA patients from 2006 to 2017 were included. Demographic, perioperative, and post-operative outcomes were evaluated. Group comparisons for continuous variables were made using an independent t-test/Mann Whitney U test and categorical data was analyzed on Chi-square/Fisher exact test; a p-value of < 0.05 was considered significant. RESULTS: Visual deterioration was the most common complaint, reported by 61.4% of nGPA patients and 81.8% of GPA patients. The mean extent of gross total resection was 47.1% in nGPA patients and 18.2% in GPA patients (p = 0.001). After surgery, tumor recurrence was seen in 1.4% of nGPA patients and 18.2% of GPA patients (p = 0.001). First re-do surgery was required in 5.7% of nGPA patients and 25.5% of GPA patients (p = 0.004). CONCLUSION: Compared to nGPAs, GPAs are more likely to present with a higher number of preoperative symptoms, and lesser chances of gross total tumor resection. GPAs are also associated with a higher rate of recurrence, which results in more follow-up procedures. Larger, multi-center longitudinal studies need to be done to validate these findings.

Breast cancer in a teenage girl with BRCA mutation: A case report from a low middle-income country.

INTRODUCTION: A staggering majority of pediatric breast masses are benign (mostly fibroadenoma) and so a biopsy is not readily performed as it can potentially lead to a future breast disfigurement. However, this should not be standard practice as this can lead to a delayed diagnosis, and hence, the treatment of pediatric breast cancer (BC); this was also seen in our patient's scenario. CASE HISTORY: Here, we report the case of the youngest known breast cancer patient in Pakistan, a 15-year-old girl. The right-sided breast lump which was diagnosed clinically as a fibroadenoma later turned out to be stage IIb pT3N0M0 metaplastic breast carcinoma with BRCA1 positivity and mutations in SMARCA4. Being young and unmarried, the patient and her family decided to opt for breast-conserving surgery with high-risk surveillance for breast and ovaries. DISCUSSION: We believe that prophylactic surgeries can be delayed with strict surveillance and thorough counseling. As pediatric BC is linked to a less favorable prognosis, every young patient diagnosed with breast cancer and their family should undergo genetic testing. BC management should be handled by specialists in the field and doctors should be trained for initial diagnostics and timely referral of patients. CONCLUSION: It is important to improve our understanding of genetic predisposition and testing in lower-middle-income countries. Considering the changing global trends, we suggest that the utilization of genetic services is direly needed to improve preventative care for at-risk individuals with breast and other cancers.

Neuropsychiatric disorders after awake craniotomy for brain tumour.

Awake-craniotomy (AC) allows maximum tumour resection while reducing the risk of permanent postoperative neurological deficits without compromising the outcomes of the treatment. AC is a potentially stressful procedure for the patients, which may lead to long-term effects on patients' psychology, and may lead to post-traumatic stress. However, there is a scarcity of data suggesting actual association of any neuropsychiatric conditions after AC. Therefore, we sought to review the neuropsychiatric conditions post awake craniotomy.

Documenting response to COVID-individual and systems successes and challenges: a longitudinal qualitative study.

BACKGROUND: This study aimed to document the evolution of perceptions of frontline healthcare workers (FHCW) regarding their well-being and the quality of health systems' response to the COVID-19 pandemic over four months in Pakistan. METHODS: We conducted this prospective longitudinal qualitative study during the four months (June-September 2020) coinciding with the peak and trough of the first wave of Pakistan's COVID-19 pandemic. We approached frontline healthcare workers (physicians and nurses) working in emergency departments (ED) in two hospitals using the WhatsApp group of the Pakistan Society of Emergency Physicians (PSEM). Participants were asked to self-record their perception of their wellness and their level of satisfaction with the quality of their hospitals' response to the pandemic. We transcribed, translated, and analysed manually using MAXQDA 2020 software and conducted the thematic analysis to identify themes and sub-themes. RESULTS: We invited approximately 200 FHCWs associated with PSEM to participate in the study. Of the 61 who agreed to participate, 27 completed the study. A total of 149 audio recordings were received and transcribed. Three themes and eight sub-themes have emerged from the data. The themes were individual-level challenges, health system-level challenges, and hope for the future. Sub-themes for individual-level challenges were: fear of getting or transmitting infection, feeling demotivated and unappreciated, disappointment due to people's lack of compliance with COVID-19 protocols, physical exhaustion, and fatigue. For the healthcare system, sub-themes were: Infrastructure, logistics, management, and communications response of the hospital/healthcare system and financial stressors. For sub-themes under hope for the future were the improved disease knowledge and vaccine development. The overall perceptions and experiences of FHCWs evolved from fear, grief, and negativity to hope and positivity as the curve of COVID-19 went down. CONCLUSION: This study shows that the individuals and systems were not prepared to deal with the challenges of the COVID-19 pandemic. The findings highlight the challenges faced by individuals and health systems during the wake of the Covid-19 pandemic. The healthcare workers were emotionally and physically taxed, while the health systems were overwhelmed by COVID-19. The overall perceptions of FHCWs evolved with time and became negative to positive as the curve of COVID-19 went down during the first wave of COVID-19 in Pakistan.

Pediatric intracranial calcified arteriovenous malformation: A case report.

BACKGROUND: Brain arteriovenous malformations (AVMs) are intracranial lesions that consist of a complex tangle of abnormal blood vessels. They can occasionally become hard and calcified. This may render these lesions difficult to resect and lead to neurological complications. There are very few reported cases of calcified brain AVMs in the literature. CASE DESCRIPTION: We report the case of an 11-year-old patient who presented with headaches and seizures exacerbated in the past 3 months. Preoperative imaging confirmed a large, right parasagittal AVM, with significant internal calcifications seen on the computed tomography angiogram. We performed a successful microsurgical resection of the calcified AVM and confirmed the diagnosis on histopathological analysis. CONCLUSION: Dense internal calcifications within AVMs are a clinical rarity and can be challenging cases for microsurgical resection.
