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

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning

Evaluation of Chromosomal Disorders in Tissue and Blood Samples in Patients with Oral Squamous Cell Carcinoma

Statement of Problem: Many studies have indicated that genetic disturbances are common findings in patients with Oral Squamous Cell Carcinoma (OSCC). Identification of these changes can be helpful in diagnostic procedures of these tumors.Purpose: The aim of this study was to appraise the chromosomal disorders in blood and tissue patients with OSCC.Methods and Materials: In this descriptive study, the study group consisted of all OSCC patients who were referred to the Faculty of Dentistry, Tehran University of Medical Sciences, Maxillofacial Surgery Clinic of Shariati Hospital, and Amir Aalam Hospital fromSeptember 2000 to November 2002. In order to study chromosomal disorders in the peripheral blood lymphocytes, 5 mL of blood was obtained from each patient In patients with the large lesion, a piece of involved tissue were obtained and cultured for 24 hours.This led to 29 blood samples and 16 tissue specimens and any relation between OSCC and age, sex, smoking and alcohol use were evaluated.Results: In this study, OSCC was more common in males than in females (3 to 5). 31% of our patients were smokers, and one had a history of alcoholic consumption. There was an increase in incidence of OSCC with age. In this study, all patients had numerical(aneuploidy, polyploidy) and structural chromosomal disorders (double minute, fragment,breakage and dicentric). There was significant difference between blood and tissue chromosomal disorders (aneuploidy, polyploidy,breakage) in OSCC patients.Conclusion: It can be concluded that chromosomes in patients with OSCC might show some genetic aberration and evaluation of involved tissue might be better way for determining this disorders

Evaluating thrombophilia in severe ovarian hyperstimulation syndrome

Background: Ovarian hyper stimulation syndrome (OHSS) and its consequences, especially thromboembolic events, are of the most dangerous complications of assisted reproductive technologies (ART). It is unclear whether a thrombophilic predisposition or changes in blood components during clinical presentation of OHSS increase thrombotic risks. Testing for certain thrombophilias in selected high risk patients may help risk assessment and decision-making about prophylactic measures. Methods: In this study carried out in April 2010 to March 2011, 108 in vitro fertilization candidates with ≥20 follicles following ovarian stimulation were recruited. Protein S, protein C, antithrombin, lupus anticoagulant and anticardiolipin antibodies were measured. Blood tests were compared between severe and non-severe OHSS groups and their changes were traced after onset of clinical OHSS in 43 patients presenting with severe symptoms by repeating the tests at hospital admission. Results: Mean protein S activity was lower in severe OHSS group (101.7±16.3 vs. 118.4±17.0 P<0.001). After clinical presentation of severe OHSS, this level decreased to 91.6±20.1 (P<0.001). Antithrombin levels decreased 2.09% after the onset of symptoms in the group with severe OHSS, but this difference was not statistically significant (P=0.051). Protein C, lupus anticoagulant and anticardiolipin antibodies were not correlated to severe OHSS development. Conclusion: Patients with relatively lower protein S activity were at higher risk for the development of severe OHSS, and its dangerous consequences. During clinical OHSS presentation, protein S decreased even more, and patients were more vulnerable to hypercoagulability states. These points should be kept in mind in risk assessment and adoption of prophylactic strategies

Carbapenemase-producing Klebsiella pneumoniae strains among clinical specimens in Kashan (2014-2015)

Background: Resistance among the Enterobacteriaceae family especially in Klebsiella genus as one important leading cause of nosocomial infection, is one of the most important health challenges all over the world. Klebsiella pneumoniae carbapenemase (KPC)-producing bacteria are among the most prevalent &beta;-lactamases in Klebsiella strains. Our aim was to study KPC-producing Klebsiella strains in clinical samples in Kashan. Materials and Methods: In this cross-sectional study Klebsiella isolates (n=181) were recovered from clinical samples during September to July 2015. After identification of Klebsiella isolates by biochemical tests, the susceptibility pattern of recovered Klebsiella from clinical isolates to 17 antibiotics were studied by disk diffusion method. Using PCR assay blaKPC gene in Klebsiella isolates were studied. Statistical analyses of data were performed by Chi square test and (P&lt;0.05) was considered statistically significant. Results: Forty eight out of 181 Klebsiella samples were multidrug resistant and the most resistant was seen to Ampicillin and Cephalotin. Among the Klebsiella isolates, 21(11.6) carried blaKPC gene which most of them were recovered in ICU ward from urinary and respiratory specimens. Conclusions: Our study showed that in Klebsiella strains isolated from patients, especially hospitalized patients in Kashan, resistance to carbapenems is seen with presence of blaKPC gene. Due to the ability of gene to spread by mobile genetic elements the finding is alarming in treatment of Klebsiella infections

Depression and infertility: evaluation of 681 infertile women using Beck depression inventory

Introduction: Infertility and depression are major problems of today&apos;s societies. Although depression is one of the most prevalent diseases in primary care practice, consult for receiving help is carried out much less than true prevalence of the disease. Therefore gathering information about prevalence and risk factors of depression is very valuable. Beck Depression Inventory (BDI) which is a screening tool for depression can be used in Iranian patients because of availability of a validated translation. The objective of this study was to estimate the prevalence of depression in infertile subjects in an infertility center. Materials and Methods: In this study, 681 infertile women were evaluated in Shariati Hospital, Tehran. Demographic information’s including age, duration, type and cause of infertility, level of education, previous treatments and smoking habits were recorded. BDI was completed by patients and score was estimated. Score of 16 and higher was assumed positive. Results: There was no relationship between age and prevalence of positive BDI score, but prevalence of positive BDI score was higher in infertilities of longer duration, infertilities caused by both male and female factors and in patients with low level of education and history of previous treatment or surgical therapy. Conclusion: Infertile patients are at risk of depression. Rate of consulting with psychiatrists and getting help is low in our country due to cultural aspects, so screening of high risk subgroups in infertile patients and referring them to psychiatrist would be very helpful
