Suicidal Callers to a National Helpline in the UK: A Comparison of Depressive and Psychotic Sufferers

Little information is available on the profile of suicidal mentally ill sufferers seeking help from helplines. In this article we describe the profile and experience with services of suicidal people calling SANELINE, a national mental health helpline in the UK. Analyses were conducted on 1,331 calls made during 1996-1997 by callers who resided in London. Sixty-one percent of all callers were female. Half of all callers were suffering from depression and 32% from psychosis. Psychotic sufferers were significantly more likely not to have been complying with treatment, to have wanted information about medication, and to have been dissatisfied with the local services. Suicidal psychotic sufferers were more likely than non-suicidal ones to have inquired about mental health laws or about state benefits. On the other hand, depressive sufferers were more likely to have wanted information about social support groups, and to have complained about the lack of services in their area of residence. The findings suggested the need to target male sufferers, to meet the information needs of suicidal people with psychosis or depression, and to increase awareness about available sources of help.     

Management of Esophageal Perforation in 120 Consecutive Patients: Clinical Impact of a Structured Treatment Algorithm

Introduction

The therapy of esophageal perforation is still challenging. The aim of this study was to assess the etiology, specific treatment, and outcome of esophageal disruption in order to generate an optimal therapeutic approach to improve patient’s outcome.

Methods

We reviewed the cases of 120 consecutive patients with esophageal perforation treated within 10 years.

Results

Iatrogenic perforation was the most frequent cause of esophageal perforation (58.3 %); Boerhaave’s syndrome was detected in 15 cases (6.8 %). Surgery was performed in 66 patients (55 %), 17 (14 %) patients received conservative treatment and 37 (31 %) patients underwent endoscopic stenting after tumorous perforation. Statistically significant impact on mean survival had Boerhaave’s syndrome (p?=?0.005), initial sepsis (p?=?0.002), pleural effusion/empyema (p?=?0.001), mediastinitis (p?=?0.003), peritonitis (p?=?0.001), and redo-surgery (p?=?0.000). Overall mortality rate was 11.7 %, in the esophagectomy group 17 % and in the patients with Boerhaave’s syndrome 33.3 %.

Conclusions

An approach considering etiology and extent of perforation, diagnostic delay, and septic status is required to improve patient’s outcome. Primary repair is feasible in patients without intrinsic esophageal disease and evidence of sepsis. The greater the diagnostic delay, the more the destruction of the esophageal wall especially in the case of septic esophageal disease, thus the stronger the argument for esophagectomy if anatomically and/or oncologically possible.     

Identification of Candida species in the clinical laboratory: a review of conventional,commercial, and molecular techniques

In healthy individuals, Candida species are considered commensal yeasts of the oral cavity. However, these microorganisms can also act as opportunist pathogens, particularly the so‐called non‐albicans Candida species that are increasingly recognized as important agents of human infection. Several surveys have documented increased rates of C. glabrata, C. tropicalis, C. guilliermondii, C. dubliniensis, C. parapsilosis, and C. krusei in local and systemic fungal infections. Some of these species are resistant to antifungal agents. Consequently, rapid and correct identification of species can play an important role in the management of candidiasis. Conventional methods for identification of Candida species are based on morphological and physiological attributes. However, accurate identification of all isolates from clinical samples is often complex and time‐consuming. Hence, several manual and automated rapid commercial systems for identifying these organisms have been developed, some of which may have significant sensitivity issues. To overcome these limitations, newer molecular typing techniques have been developed that allow accurate and rapid identification of Candida species. This study reviewed the current state of identification methods for yeasts, particularly Candida species.     

The influence of epigenetics in relation to oral health

The immune response is influenced by genetic and epigenetic factors, as well as disease and environmental factors. The term ‘epigenetics’ describes changes in the genome that influence the gene expression without altering the DNA sequence. In contrast to genetic changes in the DNA, epigenetic changes are reversible and are influenced by environmental factors. The aim of this study is to review the literature on epigenetic modifications with respect to oral health and inflammatory conditions in the oral cavity and to discuss the potential use of this new research field for the dental hygienists' and/or dentists' clinical work. Relevant publications were identified using the PubMed database without limits. The searches were conducted during January to March 2012 and resulted in articles published between 1912 and 2012. Key factors such as environment, diet, smoking, bacteria and inflammation were identified to be relevant to oral health. The result of this review article shows that there is a void in the research on epigenetics in relation to oral health. Identification of epigenetic modifications correlating with oral health may not only present a link between the influence of genetics and that of the environment on oral diseases but also provide new treatment models and tools for the dental professionals.     

State of the art and recommendationsKangaroo mother care: application in a high‐tech environment

Since Kangaroo Mother Care (KMC) was developed in Colombia in the 1970s, two trends in clinical application emerged. In low income settings, the original KMC model is implemented. This consists of continuous (24 h/day, 7 days/week) and prolonged mother/parent–infant skin‐to‐skin contact; early discharge with the infant in the kangaroo position; (ideally) exclusive breastfeeding; and, adequate follow‐up. In affluent settings, intermittent KMC with sessions of one or a few hours skin‐to‐skin contact for a limited period is common. As a result of the increasing evidence of the benefits of KMC for both infants and families in all intensive care settings, KMC in a high‐tech environment was chosen as the topic for the first European Conference on KMC, and the clinical implementation of the KMC model in all types of settings was discussed at the 7th International Workshop on KMC. Kangaroo Mother Care protocols in high‐tech Neonatal Intensive Care Units (NICU) should specify criteria for initiation, kangaroo position, transfer to/from KMC, transport in kangaroo position, kangaroo nutrition, parents’ role, modification of the NICU environment, performance of care in KMC, and KMC in case of infant instability. Conclusion: Implementation of the original KMC method, with continuous skin‐to‐skin contact whenever possible, is recommended for application in high‐tech environments, although scientific evaluation should continue.
