BACKGROUND: There is practice heterogeneity in the use, type, and duration of prophylactic antiseizure medications (ASMs) in patients with moderate-severe traumatic brain injury (TBI). METHODS: We conducted a systematic review and meta-analysis of articles assessing ASM prophylaxis in adults with moderate-severe TBI (acute radiographic findings and requiring hospitalization). The population, intervention, comparator, and outcome (PICO) questions were as follows: (1) Should ASM versus no ASM be used in patients with moderate-severe TBI and no history of clinical or electrographic seizures? (2) If an ASM is used, should levetiracetam (LEV) or phenytoin/fosphenytoin (PHT/fPHT) be preferentially used? (3) If an ASM is used, should a long versus short (> 7 vs...

Since wastewater treatment plants (WWTPs) were not originally designed to eliminate contaminants of emerging concern (CECs), alternative strategies like membrane bioreactor (MBR) technology are gaining importance in achieving effective CEC removal and minimising their environmental impact. In this study, composite wastewater samples were collected from the biggest WWTP in the Basque Country (Galindo, Biscay) and the performance of two secondary treatments (i.e. conventional activated sludge treatment, CAS, and MBR) was assessed...

Phenytoin (PHT) was first synthesized as a barbiturate derivative and was approved in 1953 by the Food and Drug Administration. This work aimed to review the pathophysiology, epidemiology, clinical presentation, and treatment of PHT-associated movement disorders (MDs). Studies were searched in relevant databases (ScienceDirect, Google Scholar, Excerpta Medica, Latin American and Caribbean Health Sciences Literature, Medline, and Scientific Electronic Library Online) and were selected by two reviewers irrespective of language between 1963 and 2021...

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare drug reaction that commonly presents with rash, fever, lymphadenopathy, eosinophilia, and multiorgan involvement. We present a case of this syndrome in a 31-year-old male who presented with a diffuse erythematous morbilliform rash with high fever and elevated liver enzymes. Upon history taking, the patient reported acute onset of multiple seizures that required intubation and ICU admission six weeks prior, which started 24 hours after receiving the Johnson and Johnson Janssen coronavirus disease 2019 (COVID-19) vaccine...

Pharmaceuticals and personal care products (PPCPs) can enter agricultural fields through wastewater irrigation, biosolid amendments, or urine fertilization. Numerous studies have assessed the risk of PPCP contamination, however there are no standardized methodologies for sample treatment, making the interpretation of results challenging. Various time periods between sampling and analysis have been reported (shipping, storage, etc.), but literature is lacking in the evaluation of PPCP degradation amidst this process...

The amount of freely available human phenotypic data is increasing daily, and yet little is known about the types of inferences or identifying characteristics that could reasonably be drawn from that data using new statistical methods. One data type of particular interest is electroencephalographical (EEG) data, collected noninvasively from humans in various behavioral contexts. The Temple University EEG corpus associates thousands of hours of de-identified EEG records with contemporaneous physician reports that include metadata that might be expected to show a measurable correlation with characteristics of the recorded signal...

Objective: To explore the features of imatinib mesylate (IM) plasma concentration during adjuvant therapy and clinical factors associated with IM plasma concentration in patients with high risk gastrointestinal stromal tumors (GIST), and to determine whether IM plasma concentration <1100 μg/L influences the efficacy of adjuvant therapy. Methods: A retrospective case control study method was used. Case inclusion criteria: (1) complete resection of lesion and GIST confirmed by pathology; (2) high risk classified according to modified National Institutes of Health classification system (2008); (3) administration of IM 400 mg/d for at least 1 month; (4) not taking the medication likely affecting IM pharmacokinetic, such as rifampicin, dilantin, and carbamazepine, within 1 month before blood collection...

Phenytoin demonstrates time-dependent and nonlinear pharmacokinetics (PK) within the therapeutic range of 10 to 20 μg/mL. There are discussions on the relevance of bioequivalence (BE) demonstrated in a single-dose BE study in healthy subjects to exposure under chronic use conditions in patients, particularly given that phenytoin has a narrow therapeutic index. The objective of this study was to quantitatively evaluate the appropriateness of single-dose PK BE through simulations for the phenytoin extended-capsule products...

Central nervous system (CNS) infections caused by free-living amoebae such as Acanthamoeba species and Naegleria fowleri are rare but fatal. A major challenge in the treatment against the infections caused by these amoebae is the discovery of novel compounds that can effectively cross the blood-brain barrier to penetrate the CNS. It is logical to test clinically approved drugs against CNS diseases for their potential antiamoebic effects since they are known for effective blood-brain barrier penetration and affect eukaryotic cell targets...

Objective: To compare the healing process of pressure ulcers treated with cryopreserved human amniotic membrane allograft and routine pressure ulcer care in our hospital. Methods: From January 2012 to December 2013, in a prospective randomized clinical trial (IRCT201612041335N2), 24 patients with second and third stage of pressure ulcers were enrolled in this study. All patients needed split-thickness skin grafts for pressure ulcer-wound coverage. Selected patients had symmetric ulcers on both upper and lower extremities...

BACKGROUND: Seizures account for significant morbidity and mortality early in the course of traumatic brain injury (TBI). Although there is sufficient literature suggesting short-term benefits of antiepileptic drugs (AEDs) in post-TBI patients, there has been no study to suggest a time frame for continuing AEDs in patients who have undergone a decompressive craniectomy for more severe TBI. We examined trends in a level-II trauma center in southern California that may provide guidelines for AED treatment in craniectomy patients...

RATIONALE: Phenytoin (Dilantin(®); DPH) is used to treat epilepsy but causes estrogen agonist-antagonist-like side effects. We investigated the interaction of phenytoin with estrogen receptors (ERs) α and β by computational molecular docking, ER competition binding, transcriptional assays, and biological actions, comparing outcomes with estradiol (E2), estrone (E1), and tamoxifen (TMX). EXPERIMENTAL: (1) The DPH docking to 3-dimensional crystal structures of the ERα ligand-binding domain (LBD) showed a high degree of structural complementarity (-57...

Global water shortage is placing an unprecedented pressure on water supplies. Treated wastewater is a valuable water resource, but its reuse for agricultural irrigation faces a roadblock: the public concern over the potential accumulation of contaminants of emerging concern (CECs) into human diet. In the present study, we measured the levels of 19 commonly occurring pharmaceutical and personal care products (PPCPs) in 8 vegetables irrigated with treated wastewater under field conditions. Tertiary treated wastewater without or with a fortification of each PPCP at 250 ng/L, was used to irrigate crops until harvest...

Tools specifically validated for tropical environments are needed to accurately describe the behavior of chemical contaminants in tropical ecosystems. In the present study, sampling rates (Rs) were determined for the commercial pharmaceutical-type Polar Organic Chemical Integrative Sampler (POCIS) with a 45.8cm(2) exposure surface for 35 Pharmaceutically Active Compounds (PhACs) and Endocrine Disrupting Compounds (EDCs), of which eight compounds (albuterol, atorvastatin, diltiazem, dilantin, enalapril, norfluoxetine, risperidone and warfarin) were reported for the first time...

A variety of lymphoma types have been reported in patients being treated with anticonvulsant therapy. Non-Hodgkin lymphomas have been reported twice as frequently as Hodgkin lymphomas. Association of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) with dilantin therapy is extremely uncommon. We report a case of Hodgkin lymphoma in a 25-year-old male patient who had been treated with diphenylhydantoin sodium for generalized tonic clonic seizures for 15 years. Patient presented with left cervical and axillary lymphadenopathy persisting for more than 2 years after cessation of treatment with diphenylhydantoin...

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is an adverse reaction commonly occurring with antiepileptic agents. It was earlier referred to by various names such as dilantin hypersensitivity syndrome and anticonvulsant hypersensitivity syndrome. It is characterized by the triad of fever, skin eruption, and systemic involvement. DRESS syndrome has also been reported with a number of other drugs including allopurinol, minocycline, terbinafine, sulfonamides, azathioprine, dapsone, and antiretroviral agents such as abacavir and nevirapine...

The objective of this study was to evaluate the stability of two phenytoin sodium suspensions in 0.9% sodium chloride solution for use in noninstitutional settings (where pharmacies are not present) to dispense phenytoin on a daily basis. A generic extended phenytoin sodium (Mylan) and a name brand phenytoin sodium (Dilantin) in suspension form were evaluated. Both suspensions were first assessed for degradation during frozen storage at designated time intervals. Frozen samples were compared with freshly prepared samples...

Reuse of treated wastewater to irrigate agricultural crops is increasing in many arid and semi-arid areas around the world. The presence of numerous pharmaceutical and personal care products (PPCPs) in treated wastewater and their potential transfer into food produce such as vegetables poses an unknown human health risk. The goal of this study was to identify PPCPs that have a comparatively high potential for plant uptake and translocation. A total of 20 frequently-occurring PPCPs were compared for their accumulation into four staple vegetables (lettuce, spinach, cucumber, and pepper) grown in nutrient solutions containing PPCPs at 0...

BACKGROUND: Dilantin sodium (phenytoin) is an antiepileptic drug, which is routinely used to control generalized tonic clonic seizure and partial seizure episodes. A few case reports of oral squamous cell carcinomas arising from regions of phenytoin induced gingival overgrowth (GO), and overexpression of mitogenic factors and p53 have presented this condition as a pathology with potential to transform into malignancy. We recently investigated the genetic status of p53 and H-ras, which are known to be frequently mutated in Indian oral carcinomas in GO tissues and found them to only contain wild type sequences, which suggested a non-neoplastic nature of phenytoin induced GO...

Gingival enlargement is common among patients and can be caused by a variety of etiological factors. The most common reason is poor oral hygiene and high bacterial load that leads to gingival inflammation and enlargement. Other implicated factors include systemic drugs, such as Phenytoin (Dilantin) taken by epileptic patients, Calcium Channel Blockers such as Nifedipine (Procardia) and Verapamil (Calan) for the treatment of hypertension, arrhythmia and angina. Another class of medication associated with gingival enlargement is immunosuppressive agents given to organ-transplant patients to prevent rejection of the new element, such as Cyclosporine...
