Introduction: CARNEY COMPLEX is an autosomal dominant syndrome that is defined with different tumors including myxoma in different organs, endocrine tumors and lentiginosis lesions. This is the first case report of this syndrome from Iran.Case: The patient is a 27 year old girl, referred with flank pain. Physical examination revealed hirsutism, truncal obesity, hyperpigmantasion and hypertension; Cushing's syndrome was suggested and confirmed with related classic biochemical tests. She had history of cardiac myxoma during her childhood and had been operated twice.Pituitary microadenoma and right adrenal adenoma were reported on MRI and CT-scan, respectively. Initially laparascopic right adrenalectomy was done; as expected, no remission in signs of Cushing's syndrome was observed after surgery. By laparoscopic adrenalectomy of the other site, Cushing's syndrome resolved. Pathologic report of 1st operation was adrenal adenoma with surrounding pigmented micronodular hyperplasia and of the 2nd one was just pigmented micronodular hyperplasia.Conclusion: We have reported a patient with CARNEY syndrome along with Cushing's syndrome due to bilateral adrenal hyperplasia and an adenoma in contralateral adrenal and microadenoma of the pituitary as an incidentaloma. This is a new presentation of CARNEY syndrome.

BACKGROUND: CARNEY COMPLEX (CNC) is an uncommon multisystem endocrine disorder with significant variability of clinical manifestations including mucocutaneous areas (pigmented lesions, myxomas, blue nevi, etc. ), endocrine tumors (adrenal, pituitary, thyroid glands, or testicles), and non-endocrine tumors [cardiac myxomas, psammomatous melanotic schwannomas (PMS), breast myxomas as well as ductal adenomas, and osteochondromyxomas]. To our knowledge, this is the second report of CNC in Iran, presenting with typical manifestations. Case Report: A 29-year-old man was referred to our clinic to evaluate the likelihood of CNC because of recurrent cardiac myxomas. He sometimes suffered from self-limited episodes of non-exertional palpitation, dyspnea, weakness, and pallor. He had some features of acromegaly (such as increase in acral size and frontal bossing). The laboratory tests revealed a high insulin-like growth factor 1 (IGF1) level, with no growth hormone (GH) suppression after oral glucose tolerance test (OGTT). Pituitary magnetic resonance imaging (MRI) showed a microadenoma (5. 79 × 2. 80 mm) of the pituitary gland; then, he was diagnosed with CNC, having the following major criteria: recurrent cardiac myxomas, skin myxomas, and acromegaly due to GH pituitary microadenoma, as well as minor criteria: multiple cafe´-au-lait (CAL) spots, several skin tags and moles, and thyroid nodules. In this patient, laboratory tests for Cushing’ s syndrome were equivocal, whereas pheochromocytoma was proven biochemically but unexpectedly pathology did not confirm it. Rather, the pathology of the right adrenocortical specimen revealed nodular hyperplasia. CONCLUSION: For patients with recurrent cardiac myxoma, especially with skin myxoma, the diagnosis of CNC should be considered and the search for other associations should be done even in an asymptomatic patient.

CARNEY COMPLEX (CNC) is a rare genetic disease. Here, we report a case of CNC and explore clinical manifesta-tions and gene mutation studies of CNC. A male patient with CNC at the age of 16 yr was admitted to Affiliated Hospital of Zunyi Medical University in July, 2015. Although the patient had typical signs of Cushing's syn-drome, he also presented with certain rare signs of Cushing's syndrome, such as "freckle-like" scattered spots of pigmentation on the face and around the lips. In addition, concomitant severe osteoporosis led to flattened ver-tebrae and the compression of corresponding levels of the spinal cord. Radiographic findings revealed adrenal nodular hyperplasia. Based on sequencing, 2 novel heterozygous mutations of the PRKAR1A gene were found. CNC was eventually diagnosed via pathologic biopsy. After 1 year of follow-up, the patient exhibited weight loss, relief of low back pain, normal blood biochemical indicators and cortisol levels at the lower limit of the normal range.

Introduction: Men with unexplained infertility and azoospermia are often observed in the context of genetic defects. The expression of a wide variety of genes is developmentally regulated  during human meiosis. Synaptonemal Protein 3 (SYCP3) gene, located on chromosome 12, encodes a DNA-binding protein as the structural component of the synaptonemal COMPLEX,which mediates the synopsis or homologous pairing of chromosomes during meiosis. Absence of SYCP3 in mice may lead to male infertility as well as female sub-fertility. SYCP3 expression analysis could be a tool for the prediction of human spermatogenesis progression, especially in infertile men.Materials & Methods: SYCP3 mRNA expression in testicular samples of 110 patients with non-obstructive azoospermia were studied in Avesina Infertility Clinic in Tehran, Iran during 2005 and early 2006. Semi-quantitative nested reverse transcriptase-PCR was employed in order to find the strength of gene expression. Using histopathological scoring for all samples, the expression level of SYCP3 during spermatogenesis was also evaluated.Results: Testicular SYCP3 mRNA expression was observed in 67 patients (60.9%). The expression level correlated with the degree of spermatogenic failure (p<0.0001). While this gene had been expressed in patients with hypo-spermatogenesis and maturation arrest, a lack of expression was seen in those with spermatogonial arrest, Sertoli cell-only syndrome and testicular atrophy.Conclusion: These data indicate that SYCP3 is expressed in the human testis and it is restricted to germ cells. Our findings, in association with those obtained in experimental animals, show that lack of SYCP3 expression may have negative effects on spermatogenesis and male fertility. SYCP3 gene expression may help detect specific spermatogenesis stages in conjunction with histopathological findings.

Two spotted spider mite (Tetranychus urticae COMPLEX) is an important pest of  egg-plant in Iran. In the present study, population of eggs and active stages and amount of losses of the spider mite were determined on upper and lower leaves of nine egg-plant cultivars in Varamin during 2001-2002. The experiment was in a randomized complete block design with three replications. Each plot consisted of four rows and on each row ten egg-plants were cultivated. Spider mite population on all cultivars was checked at weekly samplings, from July to October. Number of mites (eggs and active stages) on upper and lower leaves were then counted by stereo binocular microscope. Loss percent of mite was assessed by measuring the weight of ten randomly selected fruits of each cultivar in three replications at fifteen day intervals during fruiting period. Analysis of variance on data showed significant differences of mite population on upper and lower leaves of different cultivars and also among the cultivars. In 2000, the highest mean populations of active mites on lower leaves, 37.80 and 46.87, and on upper leaves, 27.19 and 38.08 were recorded on Borazjan cv. in naturally and artificially infested treatments, respectively. In 2001, egg and active mite populations on cultivar were significantly different only in artificially infested treatment. The maximum numbers of eggs (63.47) and active stage (107.94) were recorded on Imami 905 cultivar. Maximum and minimum losses of 69.42% and 12.86% were recorded on Imami 905 and Ghalami Varamin cultivars. These cultivars were determined as the most susceptible and resistant cultivars to mite damage, respectively.
