The objective of the study was to target clonazepam (CZ) to the brain through the intranasal olfactory mucosa using nanolipid carriers loaded with superparamagnetic iron oxide nanoparticles (SPION) to allow nanocarrier guidance and retention with an external magnetic field. For improved delivery the nanolipid carriers were incorporated in a thermosensitive mucoadhesive in situ gel. Different nanolipid carriers including solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) were prepared and characterized with respect to particle size, zeta potential, entrapment efficiency and in vitro release...

A novel methodology using liquid-liquid extraction with low temperature partitioning (LLE-LTP) and paper spray mass spectrometry (PS-MS) was developed to identify and quantify benzodiazepines in beverages. Four types of alcoholic beverages usually consumed in parties and bars were spiked with five distinct benzodiazepines (diazepam, alprazolam, bromazepam, clonazepam and cloxazolam) simulating a drug facilitated crime occurrence. The direct PS-MS analysis of the spiked beverages revealed a remarkable matrix effect with an unclear detection of protonated benzodiazepines...

SCN2A mutations have been identified in various encephalopathy phenotypes, ranging from benign familial neonatal-infantile seizure (BFNIS) to more severe forms of epileptic encephalopathy such as Ohtahara syndrome or epilepsy of infancy with migrating focal seizure (EIMFS). Thus far, no particularly effective treatment is available for severe epileptic encephalopathy caused by SCN2A mutations in children. We present the case of a boy who developed seizures on the third day of life and received a diagnosis of EIMFS based on his clinical presentations and electroencephalography reports...

Non-ketotic hyperglycaemic hemichorea-hemiballismus (NHHH) is commonly seen among elderly Asian women with type 2 diabetes mellitus. Here, we present a case of a 16-year-old Filipina with type 1 diabetes mellitus who is poorly compliant to her medications and subsequently developed right hemichorea-hemiballismus (HH). She was initially admitted with hyperglycaemia but was negative for ketonuria or metabolic acidosis. Neuroimaging showed bilateral lentiform nuclei and left caudate hyperdensities on CT and T1-weighted hyperintensity on MRI...

Pitt-Hopkins syndrome (PTHS), belonging to the group of 18q-syndromes, is a rare genetic disorder caused by mutations in TCF4. PTHS is characterized by distinctive facial appearance, intermittent hyperventilation, intellectual disability and developmental delay. Although patients with PTHS generally have various systemic symptoms, most of themwith a TCF4 mutation manifest the central nervous system (CNS) disorders. We described the first Chinese case with Pitt-Hopkins syndrome based on clinical presentations and genetic findings...

In France, prescription of narcotics must be written on a tamper-resistant prescription form with specific technical particularities. Dosage and daily dose of medicines shall be written out entirely in letters. These prescription forms are also mandatory for buprenorphine, clorazepate, clonazepam, tianeptine, buccal midazolam and zolpidem owing to traffic, abuse or diversion. In 2012, to assess the use of standard and tamper-resistant prescription forms and the acceptability of the generalization of the latter to all medicines, a national opinion survey was performed, with a postal questionnaire, within 3 randomized samples of 1,500 prescribers (physicians, dentists and midwives)...

Designer benzodiazepines have recently emerged as a class of new psychoactive substances. These substances are used in recreational settings and as alternatives to prescription benzodiazepines as self-medication for patients suffering from anxiety or other mental disorders. Due to the limited information available on the metabolic fate of these new substances, it is challenging to reliably detect their usage in bioanalytical (e.g. clinical and forensic) settings. The objective of this study was to investigate the in vitro Phase I and Phase II metabolism of the new designer benzodiazepine cloniprazepam and identify potential biomarkers for its detection in human biological fluids...

Tardive dyskinesia (TD) encompasses the spectrum of iatrogenic hyperkinetic movement disorders following exposure to dopamine receptor-blocking agents (DRBAs). Despite the advent of atypical or second- and third-generation antipsychotics with a presumably lower risk of complications, TD remains a persistent and challenging problem. Prevention is the first step in mitigating the risk of TD, but early recognition, gradual withdrawal of offending medications, and appropriate treatment are also critical. As TD is often a persistent and troublesome disorder, specific antidyskinetic therapies are often needed for symptomatic relief...

Profound deafness is a lifelong impairment, leading to the physical disability as well as poor psychological adjustment. We herein present a mental health disorder rarely seen among the patients of profound deafness. A 16-year deaf and dumb girl, previously treated for depression, presented with unusual laughter, irritability, flight of ideas, decreased sleep, ideas of self importance, and decreased social functioning and educational performance. These problems were understood by the parents via sign language, who interpreted them to the interviewer...
