Abstract
UNLABELLED In this report, we describe the case in which tumoral calcinosis occurs in a patient afflicted with psoriatic arthritis. INTRODUCTION Tumoral calcinosis is a benign disease which occurs quite rarely. It is similar to a neoplasm and appears as the result of calcium deposition in the soft tissues around large joints. This disease can develop as a primary or secondary disease in patients. CASE REPORT In this report, the authors describe the case in which tumoral calcinosis occurs in a female afflicted with psoriatic arthritis. We review the patient's clinical and para clinical findings. CONCLUSIONS Our report is the first one in which an Iranian patient with psoriatic arthritis has been diagnosed to have tumoral calcinosis. Imaging and pathological examinations are the common diagnostic methods. The main treatment for that is tumor resection.

Abstract
Doxorubicin (DOX) is one of the secondary metabolites of Streptomyces peucetius var. caesius. It is a common and effective chemotherapeutic agent used for the treatment of different diseases, including lymphoma, leukemia, breast cancer, and solid tumors. However, this medicine causes cardiotoxic side effects, which limit its clinical application. The present study examined the cardiomyopathy induced by DOX via echocardiography and transmission electron microscopy (TEM). The main objective was to evaluate the capacity of echocardiography and TEM as diagnostic tools for DOX-induced cardiotoxicity. Moreover, the correlation between intracellular and functional changes due to cardiotoxicity was assessed in a rat model. Cardiomyopathy was induced in rats by two cumulative doses of DOX. Group I received DOX 12 [i.e., 12 mg/kg, intraperitoneal (IP)] and group II received DOX 15 (i.e., 15 mg/kg, IP) in six equal doses over two weeks. Group III as the control (Ctrl) group received normal saline as a vehicle. Mortality during the study was only observed in the DOX 15 group. The echocardiographic assessments revealed significant changes in ejection fraction, fractional shortening, and heart rate in the groups which received DOX. In addition, severe cardiac arrhythmia was evident in DOX-treated groups. Remarkable adverse effects, such as moderately degenerated cells and inflated mitochondria were observed in the TEM analysis of rat hearts in the DOX groups. The present study indicated that rat models are suitable for investigating DOX-induced cardiomyopathy, especially at the dose of 12 mg/kg. Furthermore, echocardiography and TEM examinations were found to be valuable methods for the determination of cardiotoxicity in rats due to DOX.

Abstract
Background and Aims Familial Mediterranean Fever (FMF) is a periodic auto-inflammatory disease with an autosomal recessive hereditary pattern. The aim of this study is to explain the spectrum of possible neurological manifestations and its genotype-phenotype correlation in patients with familial Mediterranean fever. Methods In this case series study, data of 311 FMF patients at the FMF Registration Center in Iran (http://www.fmfiran.ir/) was studied. Patient’s information was entered into a researcher designed questionnaire. Data were analyzed by SPSS software. Results The mean age of the 181 male and 130 female patients was 23.01 years, ranging from 3–78 years old. Twelve common MEFV gene analyses were performed in 311 patients, with mutated results in 187 (60.1%) patients. The most common neurological manifestations were headache in 47.26%; 64.1% of those were persistent and 35.9% had a recurrent nature. Other neurological manifestations were vertigo (83 patients, 26.7%), paresthesia (72 patients, 23.2%), tremor (53 patients, 17%), disorientation (40 patients, 12.9%), breath-holding (23 patients, 7.4%), migraine (19 patients, 6.1%), syncope (8 patients, 2.6%), epilepsy (7 patients, 2.3%), febrile seizure (4 patients, 1%), and ataxia (5 patients, 1.6%). There were no cases of stroke or metabolic disorders among these patients. Conclusion The prevalence of epilepsy among FMF patients was significantly higher than the general population. FMF patients with negative results for MEFV gene mutations had significant frequency of headache, paresthesia, breath-holding, and ataxia.

Abstract
Background Thyroid nodules are common; however, the association of two or more different tumors in the thyroid gland is unusual. We present a first case with the association of three histological types of thryroid tumors. To the best of our knowledge, this association has not been reported in the literature before. We aim here to highlight the possible coexistence of many lesions in the thyroid gland and to discuss treatment options. Case presentation We report the case of a female patient who presented with a multinodular goiter. The final pathology after total thyroidectomy found the association of a multifocal papillary thyroid microcarcinoma arising within a Hurthle cells adenoma in a lobe and a noninvasive follicular thyroid neoplasm with papillary nuclear features in the other lobe. Due to the very low risk of recurrence, the patient was not treated with radioactive iodine. Conclusions Many controversies remain about the management of Hurthle cells tumors and many variants of papillary thyroid carcinoma. Although the management of our case did not change, more studies are necessary to analyze the evolution of patients with multiple thyroid neoplasms. When discussing therapeutic options, the advantages and disadvantages should be considered case by case based on disease staging.

Abstract
Objectives: In this study, we aim to evaluate the bone mineral density (BMD) results of 2 standard sites with 3 sites including wrist in diagnosing osteoporosis. Methods: We evaluated the BMD results of 1272 individuals referred for suspected osteoporosis between 2012 and 2015. Those individuals were included with BMD at lumbar spine, femur neck, and wrist. Bone mineral density was measured using a dual-energy X-ray absorptiometry (DXA) device. Bone mineral density and T score were measured for all 3 sites. Results: There was significant correlation between wrist T score with hip T score (r = 0.606, P < .001) and lumbar T score (r = 0.527, P < .001). With BMD of 2 sites, patients had osteopenia in 46.3% and osteoporosis in 23.7%, while by adding wrist T-BMD, subjects had osteopenia in 46.6% and osteoporosis in 33%. Between BMD at 2 sites and 3 sites, there was concordance in 81.9%, minor discordance in 17.6%, and major discordance in 0.5%. Conclusions: We observed discordance between BMD measurements of 2 sites and 3 sites, with latter detecting more cases with osteoporosis. In fact, measurement of T scores of wrist along with lumbar and femur neck improves the diagnosis.

Abstract
The metaplastic breast cancers are rare lesions, accounting for less than 1 % of all breast malignancies. According to the WHO classification (2012), the spindle cell carcinoma of the breast figures among variants of metaplastic carcinomas. The average age at diagnosis is 53 years, and the usual course is fast. Their prognosis is more pejorative than the classic invasive ductal carcinoma. The differential diagnosis arises with sarcomas, especially phyllodes sarcomas but also with other primary breast sarcomas which remain rare. The distinction of this entity is important for further management of patients which is similar to that of conventional infiltrating carcinoma.

Abstract
During a postnatal critical period balance of excitation/inhibition in the developing brain is highly regulated by environmental signals. Compared to the visual cortex, rare document includes effects of sensory experience on the hippocampus, which is also bombarded by sensory signals. In this study, basic and tetanized field excitatory postsynaptic potentials (fEPSPs) were recorded in CA1 area of hippocampus of light-(LR) and dark-reared (DR) rats (at 2, 4 and 6weeks of age). Also, we assessed age- and activity-dependent changes in the N-Methyl-d-aspartic acid (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors subunit compositions and, GABA producing enzymes. While the sensory deprivation increased amplitude of baseline fEPSPs, it decreased degree of potentiation of post-tetanus responses. Expression of GluA1 and GluA2 subunits of AMPA receptors was increased across age in DR rats. In contrast to LR rats, mRNA and protein expression of GluN1, GluN2A and GluN2B subunits of NMDA receptors was decreased in DR ones. Also, dark rearing diminished expression of GABA synthesis enzymes GAD65 and GAD67. These results indicate that, sensory experience adjusts synaptic plasticity and might also affect the balance of excitation/inhibition in the hippocampus.

Abstract
Cogan's syndrome (CS) is a chronic inflammatory disorder of unknown etiology that most commonly affects young adults. Clinical hallmarks are bilateral interstitial keratitis and vestibuloauditory dysfunction. Association between CS and systemic vasculitis as well as aortitis also exists. The diagnosis of CS is based upon presence of characteristic inflammatory eye disease and vestibuloauditory dysfunction. We describe classic Cogan's syndrome in a 47-year-old female from Ardabil. The patient was admitted with headache, vertigo, nausea, vomiting, right leg claudication, musculoskeletal pains, bilateral hearing loss, and blindness for the past two months. Ophthalmologic examination revealed that visual acuity was 0.1 bilaterally. Conjunctival hyperemia, bilateral cataract, and interstitial keratitis were detected with a slit lamp examination. Pure tone audiogram (PTA) and auditory brain stem response (ABR) showed bilateral sensorineural hearing loss. The other differential diagnosis of CS was studied and ruled out. Pulse i.v. methylprednisolone and cyclophosphamide were given and were followed by oral prednisolone and cyclophosphamide. Clinical follow-up showed partial improvement.

Abstract
OBJECTIVE Ochronosis is a term used to describe pigment deposition that occurs in the connective tissues of patients with alkaptonuria, an autosomal recessive disorder that results from a deficiency of homogentisic acid oxidase. Brown or blue-gray discoloration of the skin may be seen on the axillary and inguinal areas, face, palms or soles. In addition, blue-black discoloration can be apparent on skin overlying cartilage in which the pigment is deposited, such as the ears. The sclerae are also typically involved. The cheapest screening test to perform prior to expensive lab tests is the urine oxidation test: having it standing in light for a period of 24 h when suspicion has risen. METHODS Retrospective analysis of patients with ochronotic arthropathy seen between September 2011 to September 2013 was carried out. RESULTS Seven patients (four male, three female) with ochronotic arthropathy were seen, their mean age was 46.1 years. All patients had bluish-black pigmentations of the ear cartilage and sclera. Spondylosis was seen in all, whereas peripheral arthritis was present in five patients. Moderate aortic insufficiency and calcification of the aortic valve was detected in one male patient. Urine screening for homogentisic acid was positive in all seven patients. CONCLUSION Alkaptonuria is a rare autosomal recessive disorder of the metabolism caused by deficiency of homogentisic acid oxidase. It is suggested that more widespread screening should be undertaken in order to assess the true incidence of the disorder.

Abstract
BACKGROUND AND AIM There are few reports from Iran about the epidemiology and clinical features of inflammatory bowel disease (IBD). In this study, we aimed to determine the epidemiologic profile and clinical features of ulcerative colitis (UC) in Northwest of Iran. METHODS This retrospective study covered the time period from 1998 to 2008 and included all patients of a private gasteroenterology clinic in the northwest of Iran, who had diagnosis of UC at the time of presentation or those whose diagnosis had been made later. In addition to description of epidemiology and clinical feature of disease, an attempt was made to identify factors associated with severity of disease. RESULTS A total of 105 patients including 61 females (58.1%) were evaluated. Mean age of the patients was 33.5 +/- 13.1 years. The median time interval from initiation of symptoms to diagnosis was 9 months. The commonest presentation was proctosigmoiditis. (48.6%). Among extra-intestinal manifestations, sclerosing cholangitis had the highest frequency and was found in 2 (1.9%) patients. Among all evaluated variables, only family income (the higher the income the more severe the disease) and cigarette smoking (inverse association) were find to have significant association with severity of disease. CONCLUSION A case profile of patients with ulcerative colitis from Northwest Iran suggests that the disease is seen most commonly in the third decade of life with a female preponderance. Family income and smoking influenced the course of ulcerative colitis in Iranian patients.

Abstract
Anabolic-androgenic steroids (AAS) are used in high doses by athletes to improve athletic ability, physical appearance, and muscle mass. Unfortunately, the abuse of these agents has significantly increased. It has been established that exercise and high doses of AAS may influence the hypothalamic-pituitary gonadal (H-P-G) axis, which can in turn affect the ultrastructure of the testes. However, the effect of the combination of exercise and high doses of AAS on the ultrastructure of the testes is not known. This study was undertaken in order to examine the combination effects of swimming exercise and supraphysiological doses of nandrolone decanoate on the ultrastructural changes in rat testes. Five groups of male Wistar strain albino rats were treated as follows for 8 weeks: solvent of nandrolone decanoate (peanut oil) as a vehicle (sham); nandrolone decanoate (ND) (10 mg/kg/week) - ND; exercise (1 h/day, 5 days a week) - exercise; ND (10 mg/kg/week) and exercise (1 h/day, 5 days a week) - ND-EX; and sedentary control without any injection or exercise - control. Ultrastructural changes in the rat testes were characterised by transmission electron microscopy. The number and size of Leydig cells were considerably decreased in the interstitial space in the experimental rats. The increased thickness and irregular wavy multilaminar appearance of basement membrane in the treated animals, especially in the ND-EX group, are associated with well developed myoid cells. Cytoplasm vacuolisation, vesicular-like crista of the mitochondria, numerous lipid droplets, and lysosome and phagolysosome in Sertoli cells were significantly observed in the experimental groups. Several apoptotic germ cells were considerably observed in the experimental rats (p ≤ 0.05). Exercise training seems to increase the extent of ultrastructural changes caused by supraphysiological doses of ND in rats, which in turn may affect fertility.

Abstract
Using a synchrotron irradiation system pBR322 plasmid DNA was irradiated under vacuum by monochromatic X-rays having five specific photon energies (2.147, 2.153, 2.159, 2.168 and 2.199 keV) both on and off the K-absorption peak (2.153 keV) of phosphorus. The single- and double-strand breaks (ssb and dsb) were measured as conversions of the closed circular form of DNA (form I) to open circular (form II) and linear (form III) forms respectively. Exposures to induce one strand break per molecule were lowest at the peak (2.153 keV), and highest at 2.147 keV; the ratios were 2.7 for ssb and 3.0 for dsb. The exposures for dsb were 21-26 times higher than those for ssb. When the exposures were converted to absorbed doses in grays the absorbed doses per ssb were almost independent of photon energy. This result indicates that a certain absorbed dose was necessary to induce a ssb, regardless of whether photons were absorbed by the K-shell of phosphorus or by other shells, or by other atoms. However, the absorbed dose per dsb at 2.147 keV was 1.17 times higher than that averaged over four X-ray energies above 2-153 keV, indicating that the K-shell absorption, and the subsequent Auger event, efficiently induce dsb. The results are also discussed concerning the number of photo-absorptions of the constituent atoms per DNA strand break.
