Inter-ictal assay of peripheral circulating inflammatory mediators in migraine patients under adjunctive cervical non-invasive vagus nerve stimulation (nVNS): A proof-of-concept study

Objective

To assay peripheral inter-ictal cytokine serum levels and possible relations with non-invasive vagus nerve stimulation (nVNS) responsiveness in migraineurs.

Emergency orthodontic treatment after the traumatic intrusive luxation of maxillary incisors.

Treatment of traumatically intruded teeth is based largely on empirical clinical experience rather than on scientific data. The aim of this qualitative meta-analysis was to provide an evidence base to evaluate the orthodontic repositioning approach. In a MEDLINE search of the literature in English, 14 reported patients involving 22 teeth were found to have been treated by this modality. Additionally, 3 new patients, involving 9 intruded teeth and presented herein, were combined to form a total study sample of 17 subjects (7 girls, 10 boys, aged 8.9 +/- 1.2 years). Orthodontic extrusive forces were applied in the immediate posttrauma period (up to 3 months), with a variety of orthodontic appliances. Repositioning was achieved for 90.3% of the affected teeth but failed in 9.7% because of inflammatory resorption (2 teeth) or a misdiagnosis of root fracture (1 tooth). Early complications included loss of pulp vitality and external root resorption. All intruded teeth with closed root apices lost their vitality regardless of the degree of intrusion, whereas among those with incomplete apices, 45.5% that had been moderately intruded remained vital. External resorption was encountered in 54.8% of the teeth. Loss of marginal bone support was rarely encountered. Late complications included inflammatory root resorption in teeth with closed apices, in which endodontic treatment was not initially performed, and obliteration of the pulp tissue in teeth that remained vital. The results show that this method is superior to other treatment alternatives.     

Overview: Beyond guidelines and guidance—psychosocial perspectives on treatment interventions for young people with substance problems in the United Kingdom

Over the last two decades there has been accumulating evidence that both psychosocial and pharmacological treatment interventions can effect change in substance-misusing adults. Thus, treatment interventions implemented for young people with substance problems largely draw on the adult addiction experience and that of child and adolescent psychiatry and psychology. As young people with problematic drug use have different treatment needs, and require different interventions and services to those of adults, results of adult studies cannot necessarily be directly extrapolated to young people.

Over the last five years evidence has been rapidly mounting that treatment may potentially work in young people, but as yet it is not as extensive as that for adults. The interventions that appear most fruitful are those based on learning theory, e.g. cognitive behavioural therapy and family therapy. Outcome studies in young people demonstrate substantial variability in substance use and misuse following treatment. From the UK perspective, the evidence is almost entirely USA based, and these evaluations of non-UK treatment programmes for young people cannot be simply transferred or transported to UK healthcare settings. This has significant implications for practice and policy.

At this stage, 'guidelines' or 'guidance' that is available is either not directed at young people and/or is largely gleaned from the USA literature. In addition, it does not adequately capture the complexity of cases at front-line specialist settings. The management of young substance misusers in the UK is, in the main, 'beyond guidelines and guidance'.

The restricted treatment service network for young people in the UK makes the potential for undertaking studies on treatment effectiveness extremely limited, but because there is evidence of a growing number of young people requiring treatment, such specialist drug services require evaluation. Serious consideration of the establishment and funding of evaluation of treatment interventions to be delivered to young substance misusers in the UK is urgently needed.     

Neurofibromatosis type 1, hyperparathyroidism, and osteosarcoma: interplay?

Neurofibromatosis type 1 (NF 1) is a syndrome with a predisposition for benign and malignant tumor development. Of the malignant neoplasms, osteogenic sarcomas are rare but have been described. There are some reports of patients with neurofibromatosis type 1 with a parathyroid adenoma and hyperparathyroidism. Also, there are studies that imply that the parathyroid hormone plays a role in the regulation and modulation of oseogenic sarcomas in vitro. We report about a 50-year-old female suffering from neurofibromatosis type 1, with a 3-year documented history of untreated hyperparathyroidism and a parathyroid adenoma. The patient developed a mandibular osteogenic sarcoma. To our knowledge, this is the first reported case occurring in the mandible. The unusual tumor site for a patient with neurofibromatosis type 1, the conjugation with hyperparathyroidism and the rapid growth of an osteogenic sarcoma are intriguing.     

Adenocarcinoma arising in a chondroid syringoma of vulva.

Chondroid syringoma of the vulva is an extremely rare tumor. Of the previously reported cases, only one was clinically malignant. The authors describe a case of chondroid syringoma of the right labium majus from which arose a papillary adenocarcinoma. A right inguinal lymph node was replaced with metastatic adenocarcinoma.     

Incidence and prevalence of the sexual dysfunctions: A critical review of the empirical literature

The research which has assessed the incidence and prevalence of sexual dysfunctions is reviewed. Twenty-three studies are evaluated. Studies completed with community samples indicate a current prevalence of 5–10% for inhibited female orgasm, 4–9% for male erectile disorder, 4–10% for inhibited male orgasm, and 36–38% for premature ejaculation. Stable community estimates with regard to the current prevalence of female sexual arousal disorder, vaginismus, and dyspareunia are not available. Recent studies completed with clinical samples suggest an increase in the frequency of orgasmic and erectile dysfunction and a decrease in premature ejaculation as presenting problems. Desire disorders have increased as presenting problems in sex clinics, with recent data indicating that males outnumber females. Methodological limitations of these studies are identified and suggestions for future research are offered.
