Takayasu arteritis commonly affects moderate to large size arteries. Contrast enhanced MR angiography is a sensitive tool to detect Takayasu arteritis. Venous involvement in Takayasu arteritis is an extremely rare phenomenon. A young girl of 19 years age presented with intense headache for one year duration and depressive features for three months. Neuroimaging (MR angiography) reports were suggestive of Takayasu arteritis. Also there were features suggestive of significant involvement of cerebral veins. Venous involvement is a rare phenomenon in Takayasu arteritis. This case report highlights about the rare association of cerebral venous involvement in Takayasu arteritis with literature review. The possible biological mechanisms of depressive symptoms and headache are also discussed. © 2017 Elsevier GmbH

Background: To evaluate serum VEGF-A levels in squamous cell carcinoma of head and neck (SCCHN) patients and relationships with response to therapy. Materials and Methods: Serum VEGF-A levels in patients (n=72) treated with radiotherapy (RT) or radio-chemotherapy (RCT) and controls (n=40) were measured by ELISA. Results: Serum VEGF-A levels of the SCCHN cases were significantly higher (p=0.001) than in healthy controls, and in patients with positive as compared to negative lymph node status (p=0.004). Similarly, patients with advanced stage (Stage III-IV) disease had more greatly elevated levels of serum VEGF-A level than their early stage (Stage I-II) counterparts (p=0.001). In contrast, there was no significant difference (p=0.57) in serum level of VEGF-A in patients with advanced T-stage (T3-4) as compared to early stage (T1-2). Similarly, patients with distant metastasis had no significant (p=0.067) elevation in serum VEGF-A level as compared to non-metastatic disease. However, the non-responder patients had significantly higher serum VEGF-A level as compared to responders (p=0.001). Conclusions: Our results suggest that the serum VEGF-A level may be a useful biomarker for the prediction of response to therapy in SCCHN.

The prevalence of genetic variants of thiopurine S-methyltransferse (TPMT) and dihydropyrimidine dehydrogenase (DPD) in healthy controls (500) and the treatment response in 500 cases of head and neck cancer of north Indian origin was studied.Blood collected from all the subjects was used for isolation of DNA followed by genotyping studies. The cases received cisplatin and 5-fluorouracil (5-FU) or chemo-radiotherapy and treatment response was measured using WHO criteria.Low frequency of heterozygous mutant genotypes of TPMT*2 (2%), TPMT*3B (2.2%), TPMT*3C (4.6%), DPD IVS14+1G>A (3.6%) and G1601A (3%) was observed, although no homozygous mutants could be identified. Treatment response studies in cases receiving cisplatin and 5-FU or chemo-radiotherapy revealed that the number of nonresponders was higher in cases who carried variant genotypes of TPMT*3B (62.50%) or TPMT*3C (59.26%) or DPD IVS14+1G>A (61.90%). Likewise, the number of nonresponders was still higher in cases carrying combination of these genetic variants. Furthermore, the frequency of nonresponders was higher in cases who carried the variant genotypes of TPMT or DPD and were also tobacco users.Our data clearly show that TPMT and DPD genes are polymorphic in the north Indian population and may be important in determining the treatment response in cases. The data have also suggest tobacco may play an important role in determining the outcome of cancer therapy and there is an urgent need for assessment of drugs for their efficacy/toxicity in smokers compared to nonsmokers.

Obesity is a common disorder that has a significant impact on morbidity and mortality. Twin and adoption studies support the genetic influence on variation of obesity, and the estimates of the heritability of body mass index (BMI) is significantly high (30 to 70%). Variants in the fat mass and obesity-associated (FTO) gene have been associated with obesity and obesity-related phenotypes in different populations. The aim of this study was to examine the association of FTO rs9939609 with obesity and related phenotypes in North Indian subjects. .Gene variants were investigated for association with obesity in 309 obese and 333 non-obese patients. Genotyping of the FTO rs9939609 single nucleotide polymorphism (SNP) was analyzed using Restriction Fragment Length Polymorphism Analysis of PCR-Amplified Fragments. We also measured participants fasting glucose and insulin levels, lipid profile, percentage body fat, fat mass and fat free mass. .Waist to hip ratio, systolic blood pressure, diastolic blood pressure, percentage body fat, fat mass, insulin concentration, and homeostasis model assessment index (HOMA-Index) showed a significant difference between the study groups. Significant associations were found for FTO rs9939609 SNP with obesity and obesity-related phenotypes. The significant associations were observed between the rs9939609 SNP and blood pressure, fat mass, insulin, and HOMA-index under a different model. .This study presents significant association between FTO rs9939609 and obesity defined by BMI and also established the strong association with several measures of obesity in North Indian population.

The aim of this study is to investigate the impact of diabetes, a known risk factor for periodontitis, on activities of antioxidant enzymes superoxide dismutase (SOD), glutathione reductase (GR), and catalase (CAT) as well as levels of free radical damage marker malondialdehyde (MDA) in blood and saliva of individuals with chronic periodontitis (CP). Methods: Sixty patients with CP (30 patients with type 2 diabetes mellitus [DMCP] and 30 systemically healthy patients [CP]) and 60 periodontally healthy individuals (30 patients with type 2 diabetes mellitus and 30 systemically healthy patients [PH]) were included in this study. After clinical measurements, blood and saliva samples were collected. SOD, GR, and CAT activities in red blood cell lysate and saliva and MDA levels in plasma and saliva samples were spectrophotometrically assayed. An analysis of variance test followed by a post hoc test was used to compare the intragroup and intergroup variances among the study groups. Results: MDA levels in both the periodontitis groups were higher than in the periodontally healthy groups, but the difference between the CP and DMCP groups did not reach statistical significance (P >0.05). There was a highly significant difference between the CP and PH groups for all the enzymes studied except for SOD in blood. Only salivary SOD and GR activities were significantly different in the CP and DMCP groups. Conclusions: This study favors the role of oxidative stress in both diabetes and periodontitis. It shows that the compensatory mechanism of the body is partially collapsed because of excessive production of free radicals during periodontitis and is not able to cope with increased free radical generation attributable to diabetes, thereby worsening the situation.

Interleukin-6 (IL-6) encodes a cytokine protein, which causes inflammation, maintains immune homeostasis and plays an essential role in oral pathogenesis. The aim of this study was to evaluate the association between IL-6 (-174 and -572) G/C promoter gene polymorphisms and risk of OSCC among Indians.Single nucleotide polymorphism in IL-6 genes was genotyped in OSCC patients and healthy controls by PCR-RFLP method. Genotype and allele frequencies were analyzed by chi-square test and strength of associations by odds ratio with 95% confidence intervals.Frequency distribution of IL-6 (-174) G/C gene polymorphism was significantly associated with OSCC patients in comparison to healthy controls (OR: 0.541, CI: 0.356-0.822; p: 0.004. However, frequency of IL-6 (-572) G/C gene polymorphism was not significantly associated with OSCC patients (p>0.05).The genotype GC and allele C of IL-6 (-174) G/C gene polymorphism play a significant role in OSCC susceptibility.

Radiation stents made of Lipowitz metal or cerrobend alloy are commonly used to shield uninvolved tissues from electron beams used in therapeutic radiation treatment of head and neck cancers. However, studies investigating the efficacy of cerrobend shielding stent in patients with unilateral buccal carcinoma remain rare.To evaluate the efficacy of cerrobend shielding stents in minimizing the potential adverse effects of radiation on oral tissues in buccal carcinoma patients.Twenty.eight participants were selected for the study based on predetermined inclusion criteria, out of which four participants were lost to follow-.up. Half of the remaining participants. (N = 12) were randomly given cerrobend shielding stent and the remaining 12 formed the control group. The effects of radiotherapy were evaluated by using Radiation Therapy Oncology Group. (RTOG) 0435 Head and Neck adverse effects grading tool. All participants were evaluated for xerostomia, mucositis, dysphagia, salivary changes, dysguesia, pain, trismus and radiation caries at baseline and 1 and 3. months post.radiotherapy.All adverse effects were higher in control compared to study group, with post therapy difference for pain in swallowing, salivary changes, mucositis, dysphagia, dry mouth and caries being statistically significant.Cerrobend alloy can be used effectively as shielding stent to reduce the adverse effects associated with external beam radiation therapy in unilateral buccal carcinoma patients.

Breast cancer is the commonest female cancer worldwide and its propensity to metastasize negatively impacts on therapeutic outcome. Several clinicopathological parameters with prognostic/predictive significance have been associated with metastatic suppressor expression levels. The role of metastatic suppressor gene (MSG) KiSS1 in breast cancer remains unclear. Our goal was to investigate the possible clinical significance of KiSS1 breast cancer.The study was conducted on 87 histologically proven cases of breast cancer and background normal tiisue. Quantitative reverse transcriptase polymerase chain reaction (qRT PCR) and immunohistochemistry (IHC) were used to investigate KiSS1 at gene and protein levels, respectively, for correlation with several patient characteristics including age, family history, hormonal receptor status, stage, tumor size, nodal involvement and metastatic manifestation and finally with median overall survival (OS).Our study revealed (i) KiSS1 levels were generally elevated in breast cancer vs normal tissue (< 0.05). (ii) however, a statistically significant lower expression of KiSS1 was observed in metastatic vs non metastatic cases (P = 0.04). (iii) KiSS1 levels strongly correlated with T,N,M category, histological grade and advanced stage (<0.001) but not other studied parameters. (iv) Lastly, a significant correlation between expression of KiSS1 and median OS was found (P = 0.04).Conclusively, less elevated KiSS1 expression is a negative prognostic factor for OS, advancing tumor stage, axillary lymph node status, metastatic propensity and advancing grade of the breast cancer patient. Patients with negative KiSS1 expression may require a more intensive therapeutic strategy.

Epithelioid hemangioendothelioma (EHE) of the bone is extremely uncommon and consists of less than 1% of primary bone tumors. It is characterized by epithelioid endothelial cells and has variable biological behavior. EHE is more likely to occur between 20 and 30 years of age. Approximately half of EHE present with multifocal disease. Since the behavior of these tumors is intermediate, it is important to not misdiagnose EHE as an angiosarcoma. Here we describe the case of a 43-year-old male who presented with pain and swelling of the leg and ankle to Dr. Ram Manohar Lohia Hospital, India. Radiography and computed tomography of the ankle and leg were performed and suggested an expansile lytic lesion involving the distal tibia and talus bone. The lesion was excised and ankle arthrodesis performed. Histological evaluation of the lesion demonstrated the presence of EHE of the tibia and talus.

The reporting of isolated metatarsal tuberculosis in the available literature is sparse, herein we report a case of 26-year-old female who presented with insidious onset pain and swelling in her forefoot. Radiograph showed osteolysis of the first metatarsal. Magnetic resonance imaging showed osseous erosion with marrow oedema. Diagnosis was ascertained by fine needle aspiration cytology of the lesion. The patient received anti-tubercular therapy and showed good clinical outcome. This case is reported because of its rarity of involving isolated metatarsal bone as a cause of forefoot pain.
