Extracellular signal-regulated kinase-1/2 (ERK1/2) activation and expression and proliferating cell nuclear antigen (PCNA) content in normal tissues, benign and malignant (metastatic and not metastatic) human thyroid tumors were studied. In malignant tumors and follicular adenoma tissue increased PCNA expression was observed, and the amount of antigen in tumor tissue, except for follicular carcinoma, exceeded the amount in the conditionally normal tissue. Importantly, in encapsulated papillary carcinomas this excess was 85%, while in nonencapsulated, metastatic tumors PCNA content was on average more than 3 times above normal, and in the cases of most aggressive tumors with metastases in lungs – even 4 times. Total ERK content was significantly lower in tumors compared to normal tissue, except goiter. Activation of the ERK was almost completely suppressed in tumors but not in normal tissue. Thus, ERK activation is not associated with proliferative processes in thyroid tumor tissue. PCNA amount in thyroid tissue could serve as one of diagnostic and prognostic markers, and development of effective antigen inhibitors may be a promising trend in thyroid cancer treatment.

Hypothyroidism can present with variety of clinical features. But bleeding manifestations as a sole atypical presentation of hypothyroidism is extremely rare. Hemostatic disorder may be a manifestation of several underlying etiology. Here we have reported a case where a 14 yr old girl who initially presented with bleeding diathesis without any other symptoms suggestive of thyroid dysfunction but later found to be suffering from severe hypothyroidism after investigations.

Turner syndrome (TS) involves 45XO monosomy while TS variants are mostly 45XO/46XY or 45XO/46XX (with phenotype varying from female to male).

Orbitopathy is an inflammatory disorder affecting orbital and per orbital tissue. It can manifest itself with proptosis. The main cause of proptosis in adults is Graves’ Orbitopathy (GO). Recognition of GO does not exclude other causes of exophthalmos and differential diagnosis is sometimes required. The case presents the patient with Graves Disease (GD), admitted to the Department of Endocrinology due to the symptoms of active orbitopathy. The patient had significant proptosis (right eye-30mm, left eye29mm). Computed tomography showed thickening of oculomotor muscles in both eyes but also a mucous cyst localized in the right frontal sinus. The patient underwent endoscopic, intranasal removal of the lesion. Due to active, moderate to severe orbitopathy, he underwent treatment with 12 weekly pulses of intravenous methylprednisolone, followed by a 3-month prednisone therapy and orbital radiotherapy. The case describes the patient with two coexisting pathologies. Each of them could manifest itself with proptosis. The main cause of proptosis is GO. Physicians must bear in mind that in case of atypical course of GO and lack of improvement, or worsening during corticosteroid treatment, differential diagnosis should be considered. It is worth emphasizing that one of the reasons of proptosis may be a mucocoele (mucous retention cyst).

Current scientific evidence indicates the association between the elevation of triglycerides (TG), the decrease the High Density Lipoprotein Cholesterol HDLC and the increase in cardiovascular risk.

Introduction: Vitamin D Deficiency (VDD) in health care workers is thought to be widely prevalent due to poor sunlight exposure due to the nature of their work. However, there is limited information of the vitamin D status in them. Hence this study was undertaken to assess vitamin D status in health care workers based on their nature of work and employment in the hospital.

Material and Methods: The study was carried in 229 healthy health care workers in a tertiary care hospital. These subjects, who were divided in six groups as per their employability: Group-1 (Medical Officers- 37), Group-2 (Nursing Officers-44), Group-3 (O.T. staff-36), Group-4 (Nursing assistant Acute ward- 38), Group-5 (Nursing assistants Non-acute wards-37) and Group-6 (Ambulance assistants-37). They underwent clinical, biochemical and hormonal evaluation for serum 25 (OH) D, iPTH, BsALP and osteocalcin levels.

Results: There were 229 health workers with a mean age of 35.5 ± 7.5 years (range 19-52 years). A total of 45 subjects (19.6%) had VDD [25(OH) D ng/ml], and 151 (65.9%) were vitamin D insufficient [25(0Hp 20-<30 ng/ml] and rest were Vitamin D Sufficient (VDI) [25(OH) D 230 ng/ml]. Nurses and operation theatre; Staff had higher prevalence of VDD and VDI than ambulance assistants. Serum 25(OH) D levels were negatively; Correlated with PTH (r -0.156, p <0.0001), BsALP (r -0.131, p < 0.001) and osteocalcin levels (r -0.129, p S' 0.001). Prevalence of secondary hyperparathyroidism increased from 30.46% to 58.35% from VDD.

Conclusion: Vitamin D insufficiency is universal in health care workers. Absence of a PTH, BsALP and osteocalcin response was observed in more than 40% of individuals with VDD, the cause of which merits further evaluation.

Background: There has been a large set of studies on potential prognostic factors in patients with renal cell carcinoma and venous tumour thrombus. However, the epidemiological evidence for the effect on survival of many them has not been consistent. Therefore, we conducted a literature review of the studies on the prognostic factors in patients with renal cancer and tumour thrombus extending into the venous system to identify determinants with the strongest predicting potential.

Methods: We performed a literature review by searching the PubMed database for articles published from its inception until November 2015 based on clinical relevanc

Results: There have been several anatomical, histological, clinical and molecular prognostic factors identified in patients with the renal cell carcinoma and tumour thrombus. Anatomical factors of the highest prognostic potential include extent of tumour thrombus, venous wall cancer invasion, and metastases to the regional lymph nodes or distant organs. Whereas the most important histological prognostic factors include renal cell carcinoma subtype, tumour grade and presence of tumour necrosis, sarcomatoid features, microvascular, as well as the renal collecting system cancer invasion. Both clinical and molecular determinants have received a very limited amount of attention in terms of prognostic usefulness in renal cell carcinoma patients with tumour thrombus.

Conclusion: Although several anatomical, histological, clinical and molecular factors have been associated with the prognosis in patients with renal cell carcinoma and venous tumour thrombus, in majority of cases the evidence is based on retrospective and limited in size studies. Therefore, further multicetre and prospective studies are needed to better understand determinants negatively affecting outcome in patients with renal cell carcinoma and tumour thrombus.

Although a high body mass index is related to the development of cardiovascular risk factors, nowadays there are numerous evidences supporting the idea that the regional fat accumulation, its function and its endocrine products are more important than the excess of adiposity per se when considering the risk of cardiovascular disease development. In this review, we will focus on the function of the main adipokines and its role at cardiovascular level.
