Salivary Interleukin-1 Levels in Oral Squamous Cell Carcinoma: A Case-Control Study.

Objective: Oral squamous cell carcinoma (OSCC) is a prevalent malignancy with a significant impact on global health. The identification of non-invasive biomarkers for early detection and monitoring of OSCC remains crucial. Methods: A total of 100 subjects, comprising 50 patients with histopathologically confirmed OSCC and 50 age- and sex-matched healthy controls, were enrolled in the study. Salivary samples were collected from all participants and analyzed using enzyme-linked immunosorbent assays (ELISA) to measure IL-1 levels. Clinical data, including demographic information, smoking habits, and alcohol consumption, were obtained from patient records. Results: The mean salivary IL-1 level was significantly higher in OSCC patients compared to healthy controls (P < 0.001). Furthermore, subgroup analysis demonstrated that advanced stages of OSCC correlated with significantly elevated IL-1 levels when compared to early-stage OSCC (P < 0.05). Additionally, high salivary IL-1 levels were associated with a more aggressive tumor phenotype and poorer prognosis, as reflected by tumor size, lymph node metastasis, and overall survival (P < 0.01). Conclusion: This case-control study provides compelling evidence that salivary Interleukin-1 (IL-1) levels are significantly elevated in patients with OSCC.

Bilateral preretinal hemorrhage associated with Kikuchi-Fujimoto disease.

PURPOSE: To present a case of a patient with human immunodeficiency virus (HIV) disease and Kikuchi-Fujimoto disease (KFD) who presented with a unique pattern of retinopathy. OBSERVATIONS: A 7-year-old Taiwanese girl with HIV disease who was recently diagnosed with KFD had a sudden onset of blurry vision in both eyes one month after her KFD systemic symptoms had relatively resolved. Ophthalmic examination showed decreased visual acuity in both eyes (OU). On fundus examination, she had bilateral preretinal, subhyaloid, and vitreous hemorrhage that was more severe than anemic retinopathy. CONCLUSION: Ocular manifestations in Kikuchi-Fujimoto disease are rare; however, if they occur, presentations may vary. The exact etiology of the disease has remained elusive and controversial. This case is the first report of a patient with HIV disease and KFD presenting with ocular involvement. Furthermore, bilateral preretinal, subhyaloid, and vitreous hemorrhage, which was beyond anemic retinopathy, is an unprecedented manifestation of KFD that has not been previously reported. This case highlights the necessity for clinicians to consider all possible differential diagnoses when evaluating patients with similar findings to identify the best therapeutic approach and avoid unnecessary treatment.

TRP genes family expression in colorectal cancer.

UNLABELLED: Colorectal cancer (CRC) is the most common cancer of the gastrointestinal tract. Different factors are responsible for the development of CRC. Transient Receptor Potential (TRP) which is an important component of calcium channel is associated with several pathological conditions like cancer, neurodegenerative and cardiovascular diseases. Thirty members of the family of TRP ion channel in mammals have been determined till now. The aim of this study is to investigate TRPM, TRPV and TRPC gene expression levels in tumor tissues of CRC patients and to analyze the relationship of expression in tumor tissue of CRC with other known prognostic factors. MATERIAL AND METHODS: In this study, 93 CRC patients were included. The level of TRP gene expression in paraffin blocks of normal and cancerous colorectal tissue samples were studied at the level of mRNA with Real-time PCR. RESULTS: The mRNA expression level of TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 genes in 37 female and 56 male patients diagnosed with CRC was revealed lower in tumor tissue as compared to normal tissue (p < 0.05). No statistically significant differences of mRNA expression levels of other TRP genes were found. CONCLUSIONS: TRP gene family like TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 may be thought as potential genes contributing to tumorigenesis as their expression decreases in CRC as compared to normal tissues.

Rapid bovine and caprine species identification in ruminant feeds by duplex real-time PCR melting curve analysis using EvaGreen fluorescence dye.

A duplex real-time PCR assay with melting curve analysis, using the EvaGreen fluorescence dye, was developed for rapid and reliable identification of bovine and caprine in ruminant feeds. The method merges the use of bovine (Bos taurus) and caprine (Capra hircus) specific primers that amplify small fragments (bovine 96 bp and caprine 142 bp) of the mitochondrial 16S rRNA and 12S rRNA genes, respectively. DNA was isolated from heat-treated meats (133 °C/3 bar for 20 min) mixtures of bovine and caprine and was used to optimize the assay. Gene products of caprine and bovine produced two distinct melting peaks simultaneously at 82 and 86.8 °C, respectively. Duplex analysis of the reference samples showed that the detection limit of the assay was 0.003 % for bovine and 0.005 % for caprine species. The aim of this study was to develop a duplex real-time PCR assay followed by a melt curve step for sensitive, rapid, specific, and cost-effective detection of bovine and caprine species based on the amplicon melting peak in ruminant feeds to prevent Transmissible Spongiform Encephalopathies.

Somatic treatment of bipolar disorder in children and adolescents.

The currently available data from randomized, controlled trials and a considerable amount of open clinical data suggest that adolescent-onset bipolar disorder probably responds to the same agents as adult-onset bipolar disorder. Research examining psychopharmacologic treatment approaches in the early-onset bipolar disorder is limited, however. Methodologic problems include small sample sizes, lack of comparison groups, retrospective designs,and lack of standardized measures. In addition, sometimes no clear differentiation is made between mania and bipolar disorder, the latter term being used broadly in the literature. Often the studies show that symptoms improve because of treatment, but the functioning of the patients does not improve significantly. More research is clearly needed in all aspects of this disorder but especially in examining the efficacy of various types of treatment, its longitudinal course, and diagnostic issues. The indications for, and the overall duration of, long-term maintenance therapy need further study.Many adolescents and children with bipolar disorder do not respond to any of the first-line pharmacologic treatments; therefore, studies with novel agents should be extended to patients in this age range. Furthermore, physicians will probably continue to use combination therapies when confronted by either lack of efficacy or delayed onset of efficacy with a single agent. Thus, such resultant drug-drug interactions also should also be systematically studied [97].

Ocular manifestations of ataxia-telangiectasia.

PURPOSE: To report the manifestations of ataxia-telangiectasia (A-T) on the ocular sensory and motor systems. DESIGN: A prospective observational case series. METHODS: In a single tertiary care institition, a comprehensive ophthalmologic evaluation was made of patients with A-T as part of a systemic/neurologic evaluation. Sixty-three A-T patients between the ages of 2 and 28 years were examined. RESULTS: In 58 A-T patients whose visual acuity could be measured, best-corrected visual acuity in the better eye was 20/20 to 20/30 in 39 (67%), 20/40 to 20/50 in 17 (29%), and 20/60 to 20/80 in 2 (4%). The mean geometric visual acuity of the better eye was 20/31. Telangiectatic vessels were seen in the bulbar conjunctiva in 57 of 63 patients (91%) and on the skin of the face of 21 patients (33%). Twenty-four of 63 patients (38%) had strabismus. Esodeviations were the most common, seen in 15 individuals. Apraxia of horizontal gaze was observed in 19 of 63 patients (30%). Hypometric saccades were evident in 48 (76%), pursuit abnormalities in 43 (63%), and nystagmus in 18 (29%). Accommodation was deficient in the 54 patients in whom it was measured. No posterior segment vascular anomalies were detected. CONCLUSIONS: Visual acuity of 20/50 was present in 96% of the patients we examined. Telangiectatic vessels on the bulbar conjunctiva were seen in nearly every patient, though these are of no functional significance. Ocular motor abnormalities, especially strabismus, are a common finding in A-T. Poor accommodation and abnormal eye movements may lead to reading difficulty reported by patients with A-T.
