Treatment of drop attacks: Anti-seizure drug choices of pediatric neurologists in Saudi Arabia.

OBJECTIVES: To evaluate Epileptic drop attacks (EDAs) treatment options among pediatric neurologists in Saudi Arabia (SA) and to develop a recommendation scheme for the management of EDAs in SA. Epileptic drop attacks are one of the most pharmaco-resistant epileptic seizures. The different approaches to EDA treatment are influenced by a variety of factors, including pharmaceutical availability, costs, side effects, treating physicians' experience and personal preferences. METHODS: This cross-sectional study was conducted online. A structured questionnaire that aimed to measure the therapeutic options for patients with EDA was electronically distributed to pediatric neurologists across SA. It contained 21 questions, and the data were collected in Excel sheets and analyzed. RESULTS: Our study included a cohort of 71 pediatric neurologists from SA, of which male doctors represented 60%. Most of the participating pediatric neurologists had more than 10 years of experience in the field. We found that 77% of the included pediatric neurologists used valproic acid as a first-line drug in patients with EDA. Further, in the different case scenarios provided to participants, levetiracetam, clobazam, topiramate, and rufinamide were included in the initial management protocol for EDA. CONCLUSION: The majority of pediatric neurologists in Saudi Arabia chose valproic acid and/or levetiracetam as the first line of treatment for EDA. These results highlight the need for an evidence-based clinical guidelines to treat EDA.

Incidence and Risk Factors of Infections Among Diffuse Large B-cell Lymphoma and Classical Hodgkin's Lymphoma Patients in a Tertiary Care Center in Saudi Arabia: A Retrospective Cohort Study.

INTRODUCTION:  Non-Hodgkin's lymphoma (NHL) ranked fourth among all cancer types in Saudi Arabia, as reported by the Saudi Health Council in 2015. Diffuse large B-cell lymphoma (DLBCL) is the most common histological type of NHL. On the other hand, classical Hodgkin's lymphoma (cHL) ranked sixth and had a modest tendency to affect young men more frequently. Over recent decades, DLBCL patients were treated with cyclophosphamide, doxorubicin hydrochloride, oncovin, and prednisolone (CHOP) alone. Adding rituximab (R) to the standard regimen (CHOP) shows significant improvement in overall survival. However, it also has a considerable effect on the immune system, impacting complement-mediated and antibody-dependent cellular cytotoxicity and causing an immunosuppressive state through modulating T-cell immunity via neutropenia, which can let the infection spread. AIMS AND OBJECTIVES:  This study aims to evaluate the incidence and risk factors associated with infections in DLBCL patients in comparison to patients with cHL treated with doxorubicin hydrochloride (Adriamycin), bleomycin sulfate, vinblastine sulfate, and dacarbazine (ABVD). MATERIALS AND METHODS:  This study is a retrospective case-control study that included 201 patients acquired between January 1st, 2010, and January 1st, 2020. Sixty-seven patients had a diagnosis of cHL and had received ABVD, and 134 had DLBCL and had received rituximab. Clinical data were obtained from the medical records. RESULTS:  During the study period, we enrolled 201 patients, of whom 67 had cHL, and 134 had DLBCL. DLBCL patients had a higher serum lactate dehydrogenase upon diagnosis than cHL (p = 0.005). Both groups have similar response rates with complete remission/partial remission. Compared to cHL, patients with DLBCL were more likely to have advanced disease when they first presented (stage III/IV, DLBCL: 67.3 vs. cHL: 56.5; p = 0.005). DLBCL patients had an increased risk of infection as compared to cHL patients (DLBCL: 32.1 % vs. 16.4%; p = 0.02). However, patients with a poor response to treatment had an increased risk of infection compared to patients with a favorable response regardless of the type of disease (odds ratio: 4.6; p = <0.001). When using multivariate analysis, it is revealed that unfavorable therapeutic response continues to be the only predictor raising the probability of infection in the population (odds ratio: 4.2; p = 0.003). CONCLUSIONS:  Our study explored all potential risk factors for the occurrence of infection in DLBCL patients who received R-CHOP versus cHL. The most reliable predictor of an increased risk of infection during the follow-up period was having an unfavorable response to medication. To assess these results, additional prospective research is required.

Orbital bone infarction masquerading as preseptal cellulitis in a child with sickle beta-thalassaemia.

Although several ophthalmic manifestations of sickle cell disease (SCD) are common, orbital bone infarction is rare. Orbital bones have less bone marrow creating an unlikely place to develop infarction. However, having a patient with SCD presenting with periorbital swelling should warrant imaging to rule out bone infarction. We present a case of a child with sickle beta-thalassaemia who was misdiagnosed with preseptal cellulitis in the right eye. Later upon review of the subtle signs of bone infarction in imaging, she was discovered to have orbital bone infarction.
