Signs of oral dryness in relation to salivary flow rate, pH, buffering capacity and dry mouth complaints

<p>Abstract</p> <p>Background</p> <p>This study aimed to investigate the signs of oral dryness in relation to different salivary variables and to correlate subjective complaints of oral dryness with salivary flow rate.</p> <p>Methods</p> <p>312 unmedicated healthy individuals belonging to three age groups, (6–11, 12–17, and 18–40 years) were examined clinically for signs of oral dryness. Resting and stimulated saliva were collected to determine flow rate, pH and buffering capacity. A questionnaire was used to obtain information on subjective sensation of dry mouth.</p> <p>Results</p> <p>Dry lip and dry mucosa were present in 37.5% and 3.2% of the sample respectively. The proportion of subjects who complained of oral dryness (19%) showed a stimulated salivary flow rate significantly lower than non complainers. Dry lip was significantly related to low resting flow rate but pH and buffering capacity did not show any significant relation to dry lip. Dry mucosa was not related to any of the above mentioned parameters.</p> <p>Conclusion</p> <p>The finding that the stimulated salivary flow rate was reduced in subjects complaining of dry mouth is of great clinical relevance, since the reduction is expected to be reflected in compromising various salivary functions.</p

Rwanda – lasting imprints of a genocide: trauma, mental health and psychosocial conditions in survivors, former prisoners and their children

BACKGROUND: The 1994 genocide of the Tutsi in Rwanda left about one million people dead in a period of only three months. The present study aimed to examine the level of trauma exposure, psychopathology, and risk factors for posttraumatic stress disorder (PTSD) in survivors and former prisoners accused of participation in the genocide as well as in their respective descendants. METHODS: A community-based survey was conducted in four sectors of the Muhanga district in the Southern Province of Rwanda from May to July 2010. Genocide survivors (n = 90), former prisoners (n = 83) and their respective descendants were interviewed by trained local psychologists. The PTSD Symptom Scale Interview (PSS-I) was used to assess PTSD, the Hopkins Symptom Checklist (HSCL-25) to assess symptoms of depression and anxiety and the relevant section of the M.I.N.I. to assess the risk for suicidality. RESULTS: Survivors reported that they had experienced on average twelve different traumatic event types in comparison to ten different types of traumatic stressors in the group of former prisoners. According to the PSS-I, the worst events reported by survivors were mainly linked to witnessing violence throughout the period of the genocide, whereas former prisoners emphasized being physically attacked, referring to their time spent in refugee camps or to their imprisonment. In the parent generation, when compared to former prisoners, survivors indicated being more affected by depressive symptoms (M = 20.7 (SD = 7.8) versus M = 19.0 (SD = 6.4), U = 2993, p < .05) and anxiety symptoms (M = 17.2 (SD = 7.6) versus M = 15.4 (SD = 7.8), U = 2951, p < .05) but not with regard to the PTSD diagnosis (25% versus 22%, χ(2)(1,171) = .182, p = .669). A regression analysis of the data of the parent generation revealed that the exposure to traumatic stressors, the level of physical illness and the level of social integration were predictors for the symptom severity of PTSD, whereas economic status, age and gender were not. Descendants of genocide survivors presented with more symptoms than descendants of former prisoners with regard to all assessed mental disorders. CONCLUSIONS: Our study demonstrated particular long-term consequences of massive organized violence, such as war and genocide, on mental health and psychosocial conditions. Differences between families of survivors and families of former prisoners accused for participation in the Rwandan genocide are reflected in the mental health of the next generation

The aetiology and management of the gagging patient

Gagging in dental patients can be disruptive to dental treatment and may be a barrier to patient care, preventing the provision of treatment and the wearing of prostheses. This article reviews the literature on the gagging problem from English-language peer-reviewed articles from the years 1940 to 2002 found by conducting an electronic search of PubMed, coupled with additional references from citations within the articles. Dentally relevant articles have been cited wherever evidence exists, and a balanced view given in situations where there is controversy. The first section considers the normal gag reflex and factors that may be associated with the etiology of gagging, including anatomical and iatrogenic factors, systemic disorders, and psychological conditions. A review of the management of patients with an exaggerated gag reflex follows and includes strategies to assist clinicians.</p
