Study ObjectiveTo describe the experience of a tertiary pediatric and adolescent gynecology service that provides care to children and adolescents who present with vulval pain. Their presentation, associated symptoms, and management is described.DesignA retrospective analysis of all girls younger than 18 years of age who presented to the gynecology clinic of our tertiary referral Children’s Hospital between Jan 2010 and July 2016. Electronic medical records were reviewed and parameters recorded using a standardized data sheet.SettingGynecology clinic of a tertiary referral children’s hospital and private rooms of our director of gynecology.ParticipantsYoung women younger than 18 years who presented with symptoms suggestive of vulvodynia.Interventions and Main Outcome MeasuresPresenting symptoms, characteristics of associated features, treatment options, and treatment outcomes.ResultsForty-seven patients with a mean age of 11 years (range, 3-18 years) were identified. At the time of diagnosis 31/47 (65.9%) were premenarchal. Many presented with a symptom other than pain alone. In particular, 35/47 (74.4%) presented with coexisting or previous urinary symptoms. Of patients examined, most had positive cotton tip examination findings (16/17 (94.1%) and 11/13 (84.6%) for pre- and postmenarchal, respectively) with clinical inspection otherwise unremarkable.ConclusionChildren and adolescents with vulval pain have varied presentations. Many of the pre- and postmenarchal patients had coexisting urinary tract symptomatology at the time of diagnosis. This review of patients seen over 5.5 years at a pediatric tertiary referral center provides information on the presenting symptoms, examination features, and response to clinical management.  相似文献

ObjectiveTo determine whether N-acetylcysteine rinse was safe and could improve thickened secretions and dry mouth during and after radiotherapy.Patients and MethodsWe designed a prospective pilot double-blind, placebo-controlled randomized clinical trial (Alliance MC13C2). Adult patients (age ≥18 years) were enrolled if they underwent chemoradiotherapy (≥60 Gy). Patients initiated testing rinse within 3 days of starting radiotherapy. With swish-and-spit, they received 10% N-acetylcysteine (2500 mg daily) or placebo rinse solution 5 times daily during radiotherapy and 2 weeks postradiotherapy. The primary aim was to evaluate N-acetylcysteine in improvement of saliva viscosity with the Groningen Radiotherapy-Induced Xerostomia questionnaire. Secondary aims included evaluating xerostomia improvement by the same questionnaire and with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Head and Neck-35 Questions survey and adverse-event profiles. The type I error rate was 20%.ResultsThirty-two patients undergoing chemoradiotherapy were enrolled. Baseline characteristics were balanced for placebo (n=17) and N-acetylcysteine (n=15). N-acetylcysteine was better for improving sticky saliva (area under curve, P=.12). Scores of multiple secondary end points favored N-acetylcysteine, including sticky saliva daytime (P=.04), daytime and total xerostomia (both P=.02), pain (P=.18), and trouble with social eating (P=.15). Repeated measures models confirmed the findings. Taste was a major dissatisifer for N-acetylcysteine rinse; however, both testing rinses were safe and well tolerated overall.ConclusionOur pilot data showed that N-acetylcysteine rinse was safe and provided strong evidence of potential efficacy for improving thickened saliva and xerostomia by patient-reported outcome. A confirmatory phase 3 trial is required.Trial Registrationclinicaltrials.gov Identifier: NCT02123511  相似文献

Phoenixin (PNX) is a neuropeptide shown to play roles in the control of reproduction. The nucleus of the solitary tract (NTS), a critical autonomic integrating centre in the hindbrain, is one of many areas with dense expression of PNX. Using coronal NTS slices obtained from male Sprague‐Dawley rats, the present study characterised the effects of PNX on both spike frequency and membrane potential of NTS neurones. Extracellular recordings demonstrated that bath‐applied 10 nmol L‐1 PNX increased the firing frequency in 32% of NTS neurones, effects which were confirmed with patch‐clamp recordings showing that 50% of NTS neurones tested depolarised in response to application of the peptide. Surprisingly, the responsiveness to PNX in NTS neurones then declined suddenly to 9% (P < 0.001). This effect was subsequently attributed to stress associated with construction in our animal care facility because PNX responsiveness was again observed in slices from rats delivered and maintained in a construction‐free facility. We then examined whether this loss of PNX responsiveness could be replicated in rats placed on a chronic stress regimen involving ongoing corticosterone (CORT) treatment in the construction‐free facility. Slices from animals treated in this way showed a similar lack of neuronal responsiveness to PNX (9.1 ± 3.9%) within 2 weeks of CORT treatment. These effects were specific to PNX responsiveness because CORT treatment had no effect on the responsiveness of NTS neurones to angiotensin II. These results are the first to implicate PNX with respect to directly controlling the excitability of NTS neurones and also provide intriguing data showing the plasticity of these effects associated with environmental and glucocorticoid stress levels of the animal.  相似文献
