Testosterone- and Cortisol-Secreting Adrenocortical Oncocytoma: An Unusual Cause of Hirsutism
Objective. Oncocytomas of the adrenal cortex are usually benign and nonfunctional. They are rarely seen as the cause of hirsutism. Therefore, we aimed to report a case of adrenocortical oncocytoma presenting with hirsutism. Methods. We report a testosterone- and cortisol-secreting adrenal oncocytoma in a 23-year-old female patient presenting with hirsutism. Results. The patient had the complaint of hirsutism for the last year. Laboratory tests revealed total testosterone level of 4.2 ng/mL, free testosterone of >100 pg/mL, and DHEAS level of 574 µg/dL. There was no suppression in cortisol levels with 2 mg dexamethasone suppression test (5.4 µg/dL). Adrenal MRI revealed a 27×25 mm isointense solid mass lesion in the left adrenal gland and the patient underwent laparoscopic left adrenalectomy. Pathological examination confirmed the diagnosis of benign adrenocortical oncoyctoma. Conclusion. This well-characterized case describes a testosterone- and cortisol-secreting adrenocortical oncocytoma as a possible cause of hirsutism. To our knowledge, this is the second report in the literature. Adrenal oncocytomas should always be considered in the differential diagnosis of hirsutism
Alterations of thyroid volume and nodular size during and after pregnancy in a severe iodine-deficient area
WOS: 000344176900017PubMed: 24811142ObjectiveThe effects of pregnancy on thyroid nodules were investigated in a few number of studies. We aimed to evaluate the prevalence of thyroid nodules, the changes in size, volume and number of nodules during pregnancy and after delivery in pregnant women. Design and methodsThis prospective study was performed in a severe iodine-deficient area and included 83 pregnant women (mean age 30455years). We evaluated thyroid hormone levels, ultrasound examination of thyroid and urine iodine concentration (UIE) at each trimester and at 3-month post-partum period (PP). All patients with thyroid nodules >1cm underwent fine-needle aspiration biopsy (FNAB) after the last visit at the PP. ResultsTwenty-six women had thyroid nodules on thyroid ultrasonography at the first trimester. the volume of single/dominant nodule showed enlargement during pregnancy and remained at the PP; however, it was not significant (first trimester: 083 +/- 08ml; second trimester: 092 +/- 1ml; third trimester: 099 +/- 12ml; PP: 092 +/- 12ml). the maximum diameter of single/dominant nodule in the third trimester of pregnancy (126 +/- 54mm) was greater than the first trimester (119 +/- 48mm) (P=0002). the number of nodules did not change during pregnancy. the mean TV increased during pregnancy and remained 3months after delivery (P<0001), and the maximum value of TV was reached in the third trimester (142 +/- 79ml). FNAB results revealed a 66% prevalence of malignancy among the nodules. ConclusionsThyroid nodules were present in 301% of pregnant women. While size of the single/dominant thyroid nodule increased significantly during pregnancy, the number of nodules did not change
A Possible Role of Autonomous Physiological Systems in the Classification of Evolution (Poster Presentation)
The Role of Extra-Anatomic Bypass in the Surgical Treatment of Acute Abdominal Aortic Occlusion
Background: Aortic occlusion is rare catastophic pathology with high rates of mortality and severe morbidity. In
this study, we aimed to share our experience in the management of aortic occlusion and to assess the outcomes
of extra-anatomic bypass procedures. Methods: Eighteen patients who had undergone extra-anatomic bypass interventions
in the cardiovascular surgery department of our tertiary care center between July 2009 and May 2013
were retrospectively evaluated. All patients were preoperatively assessed with angiograms (conventional, computed
tomography, or magnetic resonance angiography) and Doppler ultrasonography. Operations consisted of bilateral
femoral thromboembolectomy, axillo-bifemoral extra-anatomic bypass and femoropopliteal bypass and were performed
on an emergency basis. Results: In all patients during early postoperative period successful revascularization outcomes
were obtained; however, one of these operated patients died on the 10th postoperative due to multiorgan
failure. The patients were followed up for a mean duration of 21.2±9.4 months (range, 6 to 36 months).
Amputation was not warranted for any patient during postoperative follow-up.. Conclusion: To conclude, acute aortic
occlusion is a rare but devastating event and is linked with substantial morbidity and mortality in spite of the recent
advances in critical care and vascular surgery. Our results have shown that these hazardous outcomes may
be minimized and better rates of graft patency may be achieved with extra-anatomic bypass techniques tailored according
to the patient
Direct venous spinal reabsorption of cerebrospinal fluid: a new concept with serial magnetic resonance cistemography in rabbits Laboratory investigation
Object. For nearly 100 years it has been believed that the main reabsorption of CSF occurs in arachnoid projections into the superior sagittal sinus, but a significant number of experiments and cases conflict with this hypothesis. According to recently published studies, CSF is permanently produced and absorbed in the whole CSF system. Clusters of arachnoidal villi, which are speculated to have a role in the reabsorption of CSF, have recently been revealed in the dorsal root of the spinal nerves. Huge absorptive surface areas of microvessels have been suggested to serve a putative role in reabsorption. The authors' aim was to observe direct venous connections between the subarachnoid space and the perispinal veins
Increased Bladder Wall Thickness in Diabetic and Nondiabetic Women With Overactive Bladder
Purpose: Bladder wall thickness has been reported to be associated with overactive bladder (OAB) in women. Diabetic women have an increased risk for OAB syndrome and may have an increased risk for bladder wall thickness. Methods: A total of 235 female patients aged 40 to 75 years were categorized into four groups. The first group consisted of women free of urgency or urge urinary incontinence. The second group included nondiabetic women with idiopathic OAB. The third group consisted of women with diabetes and clinical OAB, and women with diabetes but without OAB constituted the fourth group. Bladder wall thickness at the anterior wall was measured by ultrasound by the suprapubic approach with bladder filling over 250 mL. Results: The diabetic (third group) and nondiabetic (second group) women with OAB had significantly greater bladder wall thickness at the anterior bladder wall than did the controls. However, the difference was not significant between the diabetic (third group) and the nondiabetic (second group) women with OAB. Women with diabetes but without OAB (fourth group) had greater bladder wall thickness than did the controls but this difference was not significant. Additionally, the difference in bladder wall thickness between diabetic women with (third group) and without (fourth group) OAB was not significant. Conclusions: This is the first study to show that bladder wall thickness is increased in diabetic women with and without OAB. Additionally, nondiabetic women with OAB had increased bladder wall thickness. Further studies may provide additional information for diabetic and nondiabetic women with OAB, in whom the etiopathogenesis of the disease may be similar
