Thyroid tuberculosis is a rare condition, even in the populations with high prevalence of tuberculosis. It shows different clinical course, and may be asymptomatic. The incidence of thyroid tuberculosis was reported as 0.003%-0.1% in a postmortem study, however, its real incidence is not known exactly. Therefore, diagnosis of the disease may be overlooked or delayed. Consequently, it may present as an advanced stage disease with increased morbidity and mortality. Primary thyroid tuberculosis that presented with rapidly enlarging goiter together with cervical lymphadenopathy without pulmonary involvement was first reported in 1893. Fine needle aspiration biopsy together with acido-resistant staining of the aspiration material and the culture are quite valuable in the diagnosis of the disease. In this paper, we will discuss a case of thyroid tuberculosis with graves and hypoactive nodule, which diagnosed by histopathological examination of postoperative thyroidectomy material.

Aim: The aim of this study is to investigate endothelial dysfunction in psoriasis patients with non-invasive methods. Materials and Methods: Fifty-three psoriasis patients and 53 healthy individuals were included in the study. Carotid artery intimae-media thickness and brachial artery flow-mediated dilation was measured both in patient and control groups. Results: Mean age, gender, body mass index, smoking habits, anthropometric measurements and arterial blood pressure values were similar in both groups. Mean psoriasis area and severity index score of psoriasis patients was 6.35±6.81. Triglyceride level was significantly higher (p<0.05) and high density lipoprotein cholesterol level was significantly lower (p <0.05) in psoriasis patients when compared with the controls. Insulin resistance was found to be statistically higher in psoriasis patients group than the control group (p<0.05). There was no significant differences between two groups in terms of carotid artery intimae-media thickness (p>0.05); but flow-mediated dilation was found to be statistically significantly lower in psoriasis patients than the control group (p<0.05). FT3 level was also found to be statistically significantly lower in psoriasis patients than the control group (p=0.05). Conclusion: This study showed endothelial dysfunction and insulin resistance in psoriasis patients with low disease activity even in the absence of clinical cardiovascular disease. Thyroid function tests could supply information about cardiovascular risk. [ABSTRACT FROM AUTHOR]

Thionamide induced vasculitis is a multisystem disease. The patients may present with different clinical signs and findings due to organ involvement. These patients are almost always perinuclear antineutrophil cytoplasmic antibody (pANCA) or antimyeloperoxidase (MPO) positive. Clinical findings are not seen in all of the patients who are ANCA positive while using thionamide. Although symptoms usually resolve with drug discontinuation, some patients, however, require high-dose steroids, immunosuppressants, or plasmapheresis. We present here a case of alveolar hemorrhage induced by propilthiouracil (PTU) during treatment with PTU for Graves'disease; patients completely recovered with corticosteroid, cyclophosphamide, and plasmapheresis.

Amyloidosis is characterized by accumulation of amorphous, proteinaceous material in various organs and tissues of the body. Amyloid goiter is an extremely rare pathologic condition due to massive amyloid infiltration of the thyroid tissue. Clinically significant thyroid involvement is found in only a small percentage of cases, although a finding of amyloid deposit in autopsies is not infrequent. We present a case of amyloid goiter. The patient was diagnosed with rheumatoid arthritis 10 years previously and hospitalized for nephrotic levels of proteinuria. She was referred to our department for a rapid, painful growth in the thyroid gland. The patient finally underwent thyroidectomy due to progressive growth of the thyroid gland with compressive symptoms. In her thyroid pathology specimens there were amyloid deposits in the the entire thyroid tissue and in the arteriolar wall of parathyroid gland which was located intrathyroid. [ABSTRACT FROM AUTHOR]

Hyperthyroidism is a pathologic condition in which the body is exposed to excessive amounts of circulating thyroid hormones. Skeletal muscle is one of the major target organs of thyroid hormones. We evaluated hand grip strength and function in patients with overt hyperthyroidism. Fifty-one patients newly diagnosed with hyperthyroidism and 44 healthy controls participated in this study. Age, height, weight, and dominant hand of all participants were recorded. The diagnosis of hyperthyroidism was confirmed by clinical examination and laboratory tests. Hand grip strength was tested at the dominant hand with a Jamar hand dynamometer. The grooved pegboard test (PGT) was used to evaluate hand dexterity. The Duruöz Hand Index (DHI) was used to assess hand function. No significant differences were found in terms of clinical and demographic findings between the patients with hyperthyroidism and healthy controls (p > 0.05). Significant differences were found between the patients with hyperthyroidism and healthy controls regarding PGT and DHI scores (p < 0.05). Hyperthyroidism seemed to affect hand dexterity and function more than hand grip strength and seemed to be associated with reduced physical function more than muscle strength. This may also indicate that patients with hyperthyroidism should be evaluated by multidisciplinary modalities. [ABSTRACT FROM AUTHOR]

Background/aims: Inflammatory bowel disease (IBD) may also involve various extra-intestinal organs. Clinical studies have found asymptomatic/symptomatic pulmonary involvement in 1% to 6% of patients with IBD. The present study histopathologically investigated pulmonary involvement in an experimental model of colitis in order to demonstrate pulmonary tissue involvement in IBD and to expose potential etiological factors. It also explored the relation between inflammation and tissue concentrations of vascular endothelial growth factor (VEGF) and tumor necrosis factor α (TNF-α)., Methods: The study comprised 24 male Wistar albino rats. The rats were divided into four groups of six rats each. Acute colitis was induced in two separate groups using either the dextran sulphate sodium (DSS) or trinitrobenzene sulfonic acid (TNBS) method, while the other two groups were used as controls for each model of colitis. Wallace scoring was used for macroscopic assessment of colitis, and the lungs were histopathologically examined. Concentrations of VEGF and TNF-α in pulmonary tissue were measured by the enzyme-linked immunosorbent assay method., Results: The number of animals that had alveolar hemorrhage was significantly higher in the TNBS-induced colitis and DSS-induced colitis groups compared to their own control groups (p = 0.015 and p = 0.015, respectively). VEGF and TNF-α concentrations in pulmonary tissues were significantly increased in both the TNBS colitis and DSS colitis groups compared to their own control groups (p = 0.002 and p = 0.004, respectively; and p = 0.002 and p = 0.002, respectively)., Conclusions: The present study demonstrated that significant and serious histopathological changes directly associated with colitis occur in the lungs in IBD., Competing Interests: No potential conflict of interest relevant to this article was reported.

Background: The aim of this study was to evaluate the serum lipoxin A4 (LXA4) and neutrophil/lymphocyte (Ne/Ly) ratio in individuals with achieved systemic risk factors for periodontitis., Material and Methods: One hundred and eighty volunteers (69 male, 111 female) who were categorized as systemically healthy control, diabetes, hyperlipidemia, obese and menopause were recruited for this cross-sectional study. Sociodemographic characteristics and oral health behaviors were recorded via questionnaire. Clinical periodontal parameters, including plaque index (PI), gingival index (GI), probing pocket depth (PD), clinical attachment level (CAL), sulcus bleeding index (SBI) and decayed, missing, and filled teeth index (DMFT), were assessed. Systemic parameters and LXA4 levels were evaluated in serum samples., Results: Clinical periodontal parameters and DMFT were higher in subjects with achieved systemic risk factors than in healthy subjects. The systemically healthy with periodontitis group had higher serum LXA4 levels than the systemically healthy with non-periodontitis group (P<0.05). The Ne/Ly ratio was higher in the hyperlipidemic group with periodontitis than in the hyperlipidemic group with non-periodontitis (P<0.05). In the control group, serum LXA4 levels were positively correlated with the PD, CAL and SBI., Conclusions: In the presence of periodontitis, an increase in LXA4 levels and the Ne/Ly ratio in hyperlipidemic patients could contribute to the hypothesis that these parameters could be an indicator in periodontitis and its systemic risk factors.

Hyperthyroidism seemed to affect hand dexterity and function more than hand grip strength and seemed to be associated with reduced physical function more than muscle strength. This may also indicate that patients with hyperthyroidism should be evaluated by multidisplinary modalities.

Background/aims: Previous studies have shown that the prevalence of abnormal acid reflux in fibrotic lung disease patients is high, and in particular, patients with secondary pulmonary fibrosis show higher esophageal acid exposure than normal controls. There are also some findings that, in patients with pathological reflux, pulmonary fibrosis may develop. The aim of this study is to investigate if pulmonary fibrosis is involved in the pathogenesis of chronic cough due to Gastroesophageal Reflux., Materials and Methods: A prospective study was performed in twenty-one patients with chronic cough due to gastroesophageal reflux who was diagnosed as reflux esophagitis by upper gastrointestinal endoscopy, histology, and in ten healthy controls without GER or any lung disease. All participitants underwent laryngoscopic examination and gastroesophageal scintigraphy with late lung imaging. Bronchoalveolar lavage fluid total and differential cell counts, T and B cell subsets, and the concentrations of IL- 1β and TNF-α were measured., Results: Reflux extending into the proximal esophagus was noted in 52.5%, and posterior laryngitis was present in 90.5% of the patients. No evidence of pulmonary aspiration was noted in the patients with reflux on scintigraphic examination. No significant difference was found between the GER and control groups in terms of cellular content, IL-1β and TNF-α levels or mean T cell subsets and B cell counts in bronchoalveolar lavage fluid. Forced expiratory volume in one second, forced vital capacity FEV1/FVC, total lung capacity, and carbon monoxide diffusion capacity values were within normal limits in the gastroesophageal reflux group., Conclusion: Our findings do not support the hypothesis that gastroesophageal reflux leads to chronic cough by triggering alveolar epithelial injury and subsequent pulmonary fibrosis.

The present study was conducted to investigate whether caffeic acid phenethyl ester (CAPE), an active component of propolis extract, has a protective effect on amphotericin B induced nephrotoxicity in rat models. Male Wistar-Albino rats were randomly divided into four groups: (I) control group (n = 10), (II) CAPE group (n = 9) which received 10 μmol/kg CAPE intraperitoneally (i.p.), (III) amphotericin B group (n = 7) which received one dose of 50 mg/kg amphotericin B, and (IV) amphotericin B plus CAPE group (n = 7) which received 10 μmol/kg CAPE i.p. and one dose of 50 mg/kg amphotericin B. The left kidney was evaluated histopathologically for nephrotoxicity. Levels of malondialdehyde (MDA), nitric oxide (NO), enzyme activities including catalase (CAT), and superoxide dismutase (SOD) were measured in the right kidney. Histopathological damage was prominent in the amphotericin B group compared to controls, and the severity of damage was lowered by CAPE administration. The activity of SOD, MDA, and NO levels increased and catalase activity decreased in the amphotericin B group compared to the control group (P = 0.0001, P = 0.003, P = 0.0001, and P = 0.0001, resp.). Amphotericin B plus CAPE treatment caused a significant decrease in MDA, NO levels, and SOD activity (P = 0.04, P = 0.02, and P = 0.0001, resp.) and caused an increase in CAT activity compared with amphotericin B treatment alone (P = 0.005). CAPE treatment seems to be an effective adjuvant agent for the prevention of amphotericin B nephrotoxicity in rat models.
