Injuries to the bladder and ureter are uncommon but usually require prompt urological management. Due to their infrequent nature, Urologists maybe unfamiliar with managing these acute problems and may not work in specialist centres with readily available expertise in open and abdominal surgery. We aim to provide advice in the form of a consensus statement led by the Female, Neurological and Urodynamic Urology (FNUU) Section of the British Association of Urological Surgeons (BAUS), in consultation with BAUS members and consultants working in units throughout the UK, to create a comprehensive management pathway and a series of statements to aid clinicians. 相似文献

Triadimefon (TDF) is a triazole fungicide that blocks the reuptake of dopamine (DA) and leads to increased locomotor activity levels in mice and rats, effects similar to those of indirect DA agonists such as cocaine. We recently found in mice that intermittent TDF administration led to robust locomotor sensitization, a phenomenon reflecting neuronal plasticity, following challenge with the same TDF dose after a 2-week withdrawal period. The current study sought to determine whether antagonists to DA D1-like receptors (SCH 23390; SCH), DA D2-like receptors (remoxipride; Rem), ionotropic glutamate n-methyl-d-aspartate (NMDA) receptors (CPP), or ionotropic glutamate alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (NBQX) could prevent the development of TDF behavioral sensitization, therefore indicating their mechanistic involvement in TDF sensitization. Mice were treated with either vehicle, SCH (0.015 mg/kg), remoxipride (Rem, 0.3 mg/kg), CPP (2.5 mg/kg) or NBQX (10.0 mg/kg), followed 30 min later by vehicle or 75 mg/kg TDF (TDF), twice a week for 7 weeks, with locomotor activity measured post-dosing once a week. After a 2-week withdrawal period, mice were challenged with 75 mg/kg TDF or vehicle, to test for the presence of behavioral sensitization. Pretreatment with SCH, CPP, or NBQX, but not Rem, blocked the development of behavioral sensitization to TDF specifically for vertical activity. Antagonists that blocked TDF vertical sensitization also attenuated the increase in extracellular DA turnover (homovanillic acid [HVA]/DA) normally associated with this behavioral response. Therefore, DA D1, NMDA and AMPA receptors appear to be necessary for the development of behavioral sensitization to TDF. As such, TDF may be considered an environmental risk factor for behavioral dysfunctions linked to glutamatergic and dopaminergic systems. 相似文献

Over time, several exciting advances have been made in the treatment and prevention of malaria; however, this devastating disease continues to be a major global health problem and affects millions of people every year. Notably, the paucity of new efficient drug molecules and the inevitable drug resistance of the malaria parasite, Plasmodium falciparum, against frontline therapeutics are the foremost struggles facing malaria eradication initiatives. According to the malaria eradication agenda, the discovery of new chemical entities that can destroy the parasite at the liver stage, the asexual blood stage, the gametocyte stage, and the insect ookinete stage of the parasite life cycle (i.e., compounds exhibiting multistage activity) are in high demand, preferably with novel and multiple modes of action. Phenotypic screening of chemical libraries against the malaria parasite is certainly a crucial step toward overcoming these crises. In the last few years, various research groups, including industrial research laboratories, have performed large‐scale phenotypic screenings that have identified a wealth of chemical entities active against multiple life stages of the malaria parasite. Vital scientific and technological developments have led to the discovery of multistage inhibitors of the malaria parasite; these compounds, considered highly valuable starting points for subsequent drug discovery and eradication of malaria, are reviewed. 相似文献

A review of detrusor overactivity and the overactive bladder after radical prostate cancer treatment 下载免费PDF全文

There are various forms of treatment for prostate cancer. In addition to oncologic outcomes, physicians, and increasingly patients, are focusing on functional and adverse outcomes. Symptoms of overactive bladder (OAB), including urinary frequency, urgency and incontinence, can occur regardless of treatment modality. This article examines the prevalence, pathophysiology and options for treating OAB after radical prostate cancer treatment. OAB seems to be more common and severe after radiation therapy than after surgical therapy and even persisted longer with complications, suggesting an advantage for surgery over radiotherapy. Because OAB that occurs after radical prostate surgery or radiotherapy can be difficult to treat, it is important that patients are made aware of the potential development of OAB during counselling before decisions regarding treatment choice are made. To ensure a successful outcome of both treatments, it is imperative that clinicians and non‐specialists enquire about and document pretreatment urinary symptoms and carefully evaluate post‐treatment symptoms. 相似文献

Stafne bone cyst is a rare mandibular defect. It is a developmental abnormality that commonly presents as a small, well demarcated, and asymptomatic radiolucency seen at the angle of the mandible below the mandibular canal. There are usually no clinical signs nor symptoms. Diagnosis is commonly by plain X-ray, but use of more accurate imaging such as MRI is required in atypical cases. This case study reports an unusual presentation of Stafne bone cyst in the ramus of the mandible in a young man and reviews the relevant literature. 相似文献

Human herpesvirus 6 DNA levels in cerebrospinal fluid due to primary infection differ from those due to chromosomal viral integration and have implications for diagnosis of encephalitis 下载免费PDF全文

The prevalence and concentration of human herpesvirus 6 (HHV-6) DNA in the cerebrospinal fluid (CSF) of the immunocompetent in primary infection was compared with that in viral chromosomal integration. Samples from 510 individuals with suspected encephalitis, 200 young children and 310 older children and/or adults, and 12 other patients were tested. HHV-6 DNA concentration (log(10) copies/ml) was measured in CSF, serum, and whole blood using PCR. Serum HHV-6 immunoglobulin G antibody was measured by indirect immunofluorescence. Primary infection was defined by antibody seroconversion and/or a low concentration of HHV-6 DNA (<3.0 log(10) copies/ml) in a seronegative serum. Chromosomal integration was defined by a high concentration of viral DNA in serum (>/=3.5 log(10) copies/ml) or whole blood (>/=6.0 log(10) copies/ml). The prevalences of CSF HHV-6 DNA in primary infection and chromosomal integration were 2.5% and 2.0%, respectively, in the young children (<2 years) and 0% and 1.3%, respectively, in the older children and/or adults. The mean concentration of CSF HHV-6 DNA in 9 children with primary infection (2.4 log(10) copies/ml) was significantly lower than that of 21 patients with viral chromosomal integration (4.0 log(10) copies/ml). Only HHV-6B DNA was found in primary infection, whereas in viral integration, 4 patients had HHV-6A and 17 patients HHV-6B. Apart from primary infection, chromosomal integration is the most likely cause of HHV-6 DNA in the CSF of the immunocompetent. Our results show that any diagnosis of HHV-6 encephalitis or other type of active central nervous system infection should not be made without first excluding chromosomal HHV-6 integration by measuring DNA load in CSF, serum, and/or whole blood. 相似文献
