During a large outbreak of dengue serotype 3 in Pakistan in 2006, multiple serum samples were routinely collected for laboratory testing. Two hundred ninety-seven samples were collected between August and November 2006. Serological testing for dengue IgM was performed in Pakistan and polymerase chain reaction (PCR) testing for dengue RNA detection and serotyping were performed in Hong Kong. Dengue-specific IgM was detectable as early as 1 day, and dengue RNA remained detectable for up to 14 days, post-onset of illness. Further statistical analysis found that IgM status (positive, negative, or equivocal) was significantly correlated to clinical (duration of illness, severity of patient-reported arthralgia pain, the presence of any evidence of bleeding, a positive tourniquet test, shock), and other laboratory (platelet and total white cell counts) parameters. In contrast, the qualitative dengue RNA status (PCR positive or negative) was not statistically significantly correlated with any of these other parameters. The results for this population during this outbreak, obtained from single acute samples, demonstrate a wide range of intervals post-onset of illness during which dengue IgM and dengue RNA may be detected. Interestingly, in this study, the dengue IgM positivity correlates more closely with significant clinical illness than the dengue RNA positivity, which may be a feature specific to this particular outbreak.
Objectives: Aim of our study was to assess the expression of salivary Interleukin 1-beta (IL-1β) and clinical periodontal parameters in naswar users and non-users (controls). Methods: Eighty four individuals (forty-two naswar users and forty-two controls) were included in the study which was conducted between August 2017 and May 2018. Salivary IL-1β levels, plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL) was assessed in all the participants. Results: PD of 4mm (p<0.05), PD of 5-6mm (p<0.05), CAL (p<0.001) and levels of salivary IL1β (p<0.05) were significantly higher among naswar users as compared to controls while PI, BOP and number of missing teeth showed no significant difference among the two groups (p>0.05). Conclusion: Periodontal inflammatory conditions were worse and salivary IL-1β levels were elevated in naswar users as compared to controls. doi: https://doi.org/10.12669/pjms.35.3.10 How to cite this:Abbasi ZA, Hadi NI, Zubairi AM, Hosein M.

AimTo investigate the expression of salivary S100A7 levels among patients with oral submucous fibrosis (OSF) and healthy controls.MethodA total number of 60 participants were included in the study (30 OSF cases and 30 healthy controls). Demographic data was collected using a structured baseline questionnaire. Salivary S100A7 levels were quantified using enzyme-linked immunosorbent assay. Data was analyzed using Student t-test. Pearson correlation test was used to evaluate correlation between S100A7 levels and independent variables such as frequency and duration of areca nut use, gutka use, and mouth opening.ResultsThe mean value of salivary S100A7 for OSF group was 0.275 ng/ml, whereas mean value of salivary S100A7 for healthy controls was 0.195 ng/ml. Student t-test indicated that there was statistically significantly higher levels of S100A7 in OSF group as compared to healthy controls (p < .001). When the clinical variables of individual groups were analysed, a significant negative correlation was found between salivary S100A7 and duration of areca nut (p = .009) and gutka chewing (p = .03), whereas a significant positive correlation was found for mouth opening (p = .04).ConclusionOSF presented higher levels of salivary S100A7 levels as compared with healthy individuals and may be used as surrogate measure to identify subjects at risk for OSF.
Introduction Burning mouth syndrome is a painful condition of the oral cavity with ambiguous pathogenesis and diagnosis. Neuron-specific enolase is increased in several conditions including peripheral neuropathy of diabetes, ophthalmopathies, spinal cord injuries and tumors. Evidence on association of burning mouth syndrome and neuron-specific enolase is limited. Aim This study aims to evaluate neuron-specific enolase levels in primary and secondary burning mouth syndrome patients and compare the levels of neuron-specific enolase with associated conditions in secondary burning mouth syndrome. Methods One hundred and twenty-eight patients of more than 18 years of age with no gender predilection and having clinical symptoms of burning mouth syndrome and 135 healthy subjects were included. All the patients fulfilled Scala’s criteria for the diagnosis of burning mouth syndrome, including “primary” (idiopathic) and “secondary” (resulting from identified precipitating factors) burning mouth syndrome patients. Blood samples were obtained from burning mouth syndrome patients. Serum neuron-specific enolase was evaluated using enzyme-linked immunosorbent assay. To compare means and standard deviations, among primary and secondary burning mouth syndrome, data was analysed with analysis of variance and multiple comparisons test. Results The mean age of the study participants for burning mouth syndrome and healthy subjects was 53.30 and 51.6 years, respectively. Amongst the secondary burning mouth syndrome group, 32 (25%) of the patients had menopause, 15 (11.7%) had diabetes, eight (6.2%) of the patients had nutritional deficiency, seven (5.4%) had combined diabetes, menopause, and depression, six (4.6%) had combined diabetes and depression, four (3.1%) were diagnosed with Sjögren’s syndrome. A minor percentage of 2.3% (three) had gastroesophageal reflux disease, while the remaining three (2.3%) patients in the secondary burning mouth syndrome group were on anti-depressants. There was a statistically significant increase in the levels of neuron-specific enolase in primary burning mouth syndrome as compared to the secondary burning mouth syndrome and healthy groups. Among the subgroups of secondary burning mouth syndrome, diabetic individuals showed a significant increase in neuron-specific enolase level when compared with other conditions in the secondary burning mouth syndrome patients. Discussion and conclusion: The raised serum neuron-specific enolase levels in patients suffering from primary burning mouth syndrome highlight a possible neuropathic mechanism. It was also increased in the sub-group of secondary burning mouth syndrome patients having diabetes. Although it cannot be ascertained whether the deranged values in the diabetic group were due to burning mouth syndrome or due to diabetes, the raised quantity of neuron-specific enolase in the primary burning mouth syndrome group is a reliable diagnostic indicator. Future studies on the assessment of neuron-specific enolase levels as a diagnostic tool for onset and management of primary and secondary burning mouth syndrome are recommended.
