Epilepsy Surgery in Adult Stroke Survivors with New-Onset Drug-Resistant Epilepsy.

BACKGROUND: Despite its effectiveness, surgery for drug-resistant epilepsy is underutilized. However, whether epilepsy surgery is also underutilized among patients with stroke-related drug-resistant epilepsy is unclear. Therefore, our objectives were to estimate the rates of epilepsy surgery assessment and receipt among patients with stroke-related drug-resistant epilepsy and to identify factors associated with these outcomes. METHODS: We used linked health administrative databases to conduct a population-based retrospective cohort study of adult Ontario, Canada residents discharged from an Ontario acute care institution following the treatment of a stroke between January 1, 1997, and December 31, 2020, without prior evidence of seizures. We excluded patients who did not subsequently develop drug-resistant epilepsy and those with other epilepsy risk factors. We estimated the rates of epilepsy surgery assessment and receipt by March 31, 2021. We planned to use Fine-Gray subdistribution hazard models to identify covariates independently associated with our outcomes, controlling for the competing risk of death. RESULTS: We identified 265,081 patients who survived until discharge following inpatient stroke treatment, 1,902 (0.7%) of whom subsequently developed drug-resistant epilepsy (805 women; mean age: 67.0 ± 13.1 years). Fewer than six (≤0.3%) of these patients were assessed for or received epilepsy surgery before the end of follow-up (≤55.5 per 100,000 person-years). Given that few outcomes were identified, we could not proceed with the multivariable analyses. CONCLUSIONS: Patients with stroke-related drug-resistant epilepsy are infrequently considered for epilepsy surgery that could reduce morbidity and mortality.

Determinants of anxiety and depression among university teachers during third wave of COVID-19.

BACKGROUND: To estimate the determinants of anxiety and depression among university teachers in Lahore, Pakistan, during COVID-19. METHODS: A cross-sectional study was conducted by enrolling 668 teachers from the universities of Lahore, Pakistan. Data were collected using a questionnaire. Chi-square for significance and logistic regression for the association were used. RESULTS: Majorly, the university teachers, with an average age of 35.29 years, had regular jobs (72.8%), job experience of > 6 years (51.2%) and good self-reported health (55.4%). The majority of the teachers were working as lecturers (59.6%), lecturing in arts (33.5%) or general science (42.5%) departments, having MPhil (37.9%) or master (28.9%) degrees, and teaching via synchronous video (59.3%) mode. Anxiety and depression, severe and extremely severe, were higher among lecturers, MPhil or master degree holders, teachers lecturing arts and general science subjects, and in those on contract employment. Anxiety was significantly associated with academic departments; arts (OR;2.5, p = 0.001) and general science (OR;2.9, p = 0.001), poor health status (OR;4.4, p = 0.018), and contractual employment (OR;1.8, p = 0.003). Depression was associated with academic departments; arts (OR;2.7, p = 0.001) and general science (OR;2.5, p = 0.001), and health status (OR;2.3, p = 0.001). CONCLUSION: Among university teachers, anxiety and depression, severe and extremely severe, were prevalent among lecturers having MPhil or master degrees, belonging to arts and general science departments, and among contract employees. Anxiety and depression were significantly associated with academic disciplines, lower cadre, and poor health status.

Epilepsy Risk Following Bariatric Surgery for Weight Loss.

BACKGROUND AND OBJECTIVES: A previous study reported finding that epilepsy risk is elevated after bariatric surgery for weight loss; however, this association has not been adequately explored. Our objectives were to (1) estimate the risk of epilepsy after bariatric surgery for weight loss relative to a nonsurgical cohort of patients with an obesity diagnosis and (2) identify epilepsy risk factors among bariatric surgery recipients. METHODS: We conducted a population-based retrospective cohort study using linked health administrative databases in Ontario, Canada. Participants were accrued between July 1, 2010, and December 31, 2016, and followed until December 31, 2019. All Ontario residents aged 18 years and older who had bariatric surgery during the accrual period were eligible for inclusion in our exposed cohort. Patients hospitalized with a diagnosis of obesity and who did not have bariatric surgery during the accrual period were eligible for inclusion in our unexposed cohort. We excluded patients with a history of seizures, epilepsy, various seizure or epilepsy risk factors, psychiatric disorders, or drug or alcohol abuse/dependence. In our primary analysis, we used inverse probability of treatment weighting to control for confounding. A marginal Cox proportional hazards model was then used to estimate the risk of epilepsy associated with bariatric surgery. A Cox model was also used to identify epilepsy risk factors among exposed participants. RESULTS: The final sample included 16,958 exposed participants and 622,514 unexposed participants. After inverse probability of treatment weighting, the estimated rates of epilepsy were 50.1 and 34.1 per 100,000 person-years among those who did and did not have bariatric surgery, respectively. The hazard ratio for developing epilepsy after bariatric surgery was 1.45 (95% CI = 1.35, 1.56). Among participants who received bariatric surgery, stroke during follow-up increased epilepsy risk (HR = 14.03, 95% CI = 4.26, 46.25). DISCUSSION: In this study, we found that patients with a history of bariatric surgery were at increased risk of developing epilepsy. These findings suggest that epilepsy is a long-term risk associated with bariatric surgery for weight loss.

A Case of Heterotopic Ossification in Papillary Renal Cell Carcinoma Type 2.

Renal cell carcinoma (RCC) is associated with a variety of different histopathologic subtypes in which each subtype may be further subclassified. These entities carry with them unique prognoses and necessitate treatment with specific immunotherapy agents should advanced disease be uncovered. Meanwhile, aberrant physiologic processes may lead to unique histologic findings within these subtypes, further complicating management and prognostication. Heterotopic ossification within RCC is one of these rare occurrences and was once thought to have favorable prognostic implications. We report a case of a young female with papillary type 2 RCC with heterotopic ossification.

Histiocytic Sarcoma Associated with Coombs Negative Acute Hemolytic Anemia: A Rare Presentation.

Histiocytic sarcoma (HS) rarely involves extranodal sites, such as the spleen. We report a unique pediatric case of massive splenomegaly and refractory Coombs negative hemolytic anemia (CNHA) secondary to HS. The CNHA resolved completely after an emergent splenectomy. Next generation sequencing (NGS) revealed novel ASXL1, PTPN11, KIT, and TP53 mutations, unmasking a clonal heterogeneity within the same neoplasm.

Periodontal infection: a potential risk factor for pre-term delivery of low birth weight (PLBW) babies.

Pre-term delivery of low-birth-weight (PLBW) babies is considered a major peri-natal problem in many countries and is contributing substantially to infant mortality and to childhood handicap. There is a reported incidence of pre-term delivery of low-birth-weight (PLBW) babies of 37% of all live births in Pakistan, which has a tremendous impact on health care system in this community. The prevalence of periodontal disease in Pakistan is also very high in all age groups and women of child bearing age (18-34 years) are no exception. Recent studies indicate periodontal infection as a potential independent risk factor for PLBW, and is considered to be 7 times more likely to be associated than any other risk factors. Several postulated mechanisms have been reviewed, including the virulence effects and role of asymptomatic bacteraemia, focusing on the bacterial load in periodontium facilitating its transmission from oral cavity to the uterus. The indication that periodontal disease is a potential risk factor for the delivery of PLBW; a high level of periodontal disease in women of child bearing age and similar high level of PLBW babies in country, calls for further longitudinal investigations that validate a causal relationship between periodontal infection and pre-term delivery of LBW babies in Pakistan. A review of literature and preliminary communication for a planned study is presented.

Histologic findings in skin biopsy in a JMML rash: a case report and review of literature.

Juvenile myelomonocytic leukemia (JMML), belonging to the category of myeloproliferative/myelodysplastic syndromes, is a rare pediatric hematologic malignancy with frequent skin manifestations commonly in the form of rashes. However, these rashes are not always biopsied and their immunophenotype studied in details. We report one such case in a 2-year-old boy who presented with a 1-month history of nonresolving fever, fatigue, and pallor along with a generalized maculopapular skin rash. The child also had mild hepatomegaly. A complete blood count with differential revealed a hemoglobin value of 8.6 g/L, leukocytosis (white blood cell count of 55.3 × 109/L), absolute monocytosis (27 × 109/L), immature granulocytes, and a platelet count of 126 × 109/L. The bone marrow aspirate showed a hypercellular marrow with trilineage hematopoiesis, 10% blasts (including promonocytes), increased monocytes (46%), and dysplastic changes in the erythroid and myeloid cell lines. These findings along with absence of a BCR-ABL1 fusion gene and a hemoglobin F level of 3.4% were consistent with the diagnosis of JMML, which was confirmed by subsequent positive granulocyte macrophage-colony stimulating factor hypersensitivity and NRAS mutation studies. A skin biopsy of the rash revealed a dermal infiltrate composed predominantly of atypical monocytic cells that were positive for CD68, myeloperoxidase, and lysozyme and negative for CD117, CD1a, and S100, consistent with JMML.
