Radiation cystitis is a recognised complication of pelvic radiotherapy. Incidence of radiation cystitis ranges from 23 to 80% and the incidence of severe haematuria ranges from 5 to 8%. High quality data on management strategies for radiation cystitis is sparse. Treatment modalities are subclassified into systemic therapies, intravesical therapies, and hyperbaric oxygen and interventional procedures. Short-term cure rates range from 76 to 95% for hyperbaric oxygen therapy and interventional procedures. Adverse effects of these treatment strategies are acceptable. Ultimately, most patients require multimodal treatment for curative purposes. Large randomised trials exploring emergent management strategies are required in order to strengthen evidence-based treatment strategies. Urologists encounter radiation cystitis commonly and should be familiar with diagnostic modalities and treatment strategies.
Iatrogenic urethral catheterization injuries represent a significant cost and cause of patient morbidity. Despite efforts to educate and train health care professionals on urethral catheterization insertion technique, iatrogenic urethral injuries will continue to occur unless urinary catheter safety mechanics are altered and improved.
This study replicates and extends exploratory research into the occurrence of attachment behaviours and parent fixation amongst people with dementia. Relationships between cognitive functioning, pre-morbid attachment style, attachment behaviours and parent fixation were examined. Fifty-three people with dementia, living in residential or nursing homes, completed the Standardised Mini-Mental State Examination and were interviewed about their parents. A family member or friend rated pre-morbid attachment style and care staff made observations of attachment behaviour. Results indicated that parent fixation occurred more often in participants with lower levels of cognitive functioning. Parent fixation was not related to pre-morbid attachment style. The occurrence of overt attachment behaviour was inconsistently associated with both high and low levels of cognitive functioning, at different times of the day. Participants with an avoidant attachment style exhibited more overt attachment behaviour than participants with a secure attachment style. Findings are interpreted in terms of attachment theory and the clinical and research implications of the study are discussed.
Homocysteine thiolactone (HTL) elicits seizures in mice at a dose of 850 mg/kg (95-100% of animals) with an average latency time of 19.5 min. These seizures are reversed by both 5' N-ethylcarboximide adenosine (NECA) and flunitrazepam, with respective ED50 doses of 0.025 and 0.20 mg/kg. NECA was approximately four-fold more potent as an inhibitor of HTL-induced seizures than of seizures induced by pentylenetetrazol (PTZ, 75 mg/kg). Flunitrazepam was equipotent in both seizure paradigms. The purine precursor 5-amino-4-imidazole carboxamide riboside, (AICAr), although virtually ineffective against PTZ-induced seizures at doses greater than 1 g/kg, was able to inhibit HTL-induced seizures with an ED50 of approximately 350 mg/kg. The anticonvulsant effect of AICAr was dose and time dependent. The anticonvulsant potency of AICAr was increased by simultaneous administration of the adenosine uptake blocker Mioflazine, whereas the central nervous system (CNS)-impermeable adenosine uptake blocker dipyridamole had no effect. The ability of AICAr to permeate the blood-brain barrier (BBB) is limited (less than 1%) and may explain its low potency as an anticonvulsant. AICAr also has very low potency at brain adenosine A1 and A2 receptors as well as adenosine uptake sites (IC50 greater than 10(-3) M), suggesting that its anticonvulsant properties are not mediated by direct action at these sites. The results indicate that AICAr does have frank anticonvulsant effects and further suggest that HTL-induced seizures may represent a useful paradigm for evaluation of adenosinergic agents. AICAr or more potent derivatives thereof may represent a new class of anticonvulsants with the ability to target seizure foci selectively.
MBT can be a particularly effective intervention for the treatment of adults with a diagnosis of BPD and of adolescents who self-harm and mothers enrolled in substance abuse treatments. MBT can be an effective intervention for depression and eating disorders but the evidence is currently limited. Professionals supporting mothers of children at risk may benefit from receiving training in the principles of MBT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
