29 unresolved questions extracted from the limitations and future-work sections of 682 Pharmacological Effects and Toxicity Studies papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • Our findings reveal well-established hormonal and lipid pathways alongside emerging but underexplored genetic mechanisms, highlight- ing key knowledge gaps that warrant further investigation. However, evidence remains inconclusive, and larger, standardized studies are needed to validate these associations, as current research often relies on small, heterogeneous cohorts (e. Findings on adiponec- tin were inconsistent, with some studies reporting reduced levels under VPA therapy, warranting further investigation.

  • 72 process Ethicon agreed to pay Professor Ulmsten $400,000 if the early results that he had achieved with the TVT could be replicated by other surgeons. This consensus should be validated by carrying out follow up on those who have removals at the specialist centres. This consensus should be validated by carrying out follow up on those who have removals at the specialist centres. 462 A letter to its members from the British Association of Urological Surgeons (BAUS) in February 2004 recognised the lack of evidence and went on to say, ‘The European CE mark constitutes no more than recognition that the product is “fit for purpose” and it is possible for products to become registered with no clinical data at all. The outcome data that exists currently does not capture all reported symptoms, hence complication rates are not fully understood.

  • TDM has been used as a tool to optimize treatment of epilepsy for almost 50 years, and while VPA evidence for its usefulness in improving clinical outcome is scarce, TDM continues to play a role in epilepsy management for reasons: (1) physiological changes due to aging, pregnancy, nutritional status, drug interactions, and comorbidities (ie, those involving…

  • Atypical neuroleptic malignant syndrome is a difficult matter, especially when symptoms of hyperthermia or muscle rigidity is lacking, but using Levenson's or Adityanjee and Aderibigbe's criteria may increase it detectability, can permit earlier intervention and prevent development of life-threatening typical neuroleptic malignant syndrome.

  • Case Description While ppCMS's pathophysiology remains incompletely understood, prevailing hypotheses implicate cerebellothalamocortical dysregulation, functional diaschisis, and inhibitory-excitatory network imbalance.

    Lorazepam for post-operative pediatric cerebellar mutism syndrome: A case report · 2026 · DOI

  • Future research should explore whether less sedating benzodiazepines, such as clobazam, or other GABAergic modulators could provide similar benefits without the cognitive side effects associated with lorazepam.

  • While there is a potential link between discontinuing benzodiazepines and atrial fibrillation through mechanisms involving peripheral benzodiazepine receptors and cardiac calcium channels, causality remains uncertain and multifaceted.

  • Few studies were found to significantly associate the CYP2C9*2 , CYP2C9*3 , CYP2C19*2 , and CYP2C19*3 single nucleotide polymorphisms with elevated serum levels of valproic acid and carbamazepine, and valproic acid induction of hyperammonemia, and adverse reactions cutaneous for carbamazepine.

  • The circumstances under which aggressive responding may be more likely to follow benzodiazepine use remain unclear, although some evidence suggests dose and/or personality factors may influence this effect.

  • In addition there are contradictory findings regarding the use of dopamine agonists, tetrabenazine, topiramate, levatirasetame, and delta-9-tetrahydrocannabinol in these patients.

  • The mechanism of antipsychotic-induced priapism is thought to be related to blockade of alpha1 adrenergic receptors, but clinical data supporting this hypothesis are lacking.

  • Additional controlled trials in children with partial- or generalized-onset seizures, infantile spasms, and Lennox-Gastaut syndrome are warranted to further delineate zonisamide's broad spectrum of efficacy and tolerability in children.

  • Possible limitations of this study are the low dose of sodium valproate, the relatively short treatment period (three weeks), and the absence of statistical corrections for multiple comparisons.

  • Although there are several uncontrolled confounding factors, the overrepresentation of phenothiazines, especially thioridazine, among psychiatric patients who died suddenly is striking and, taken together with their well-established arrhythmogenic effects, warrants further attention.
