Case Report Papillary Thyroid Microcarcinoma with a Large Cystic Dilated Lymph Node Metastasis to the Neck Mimicking a Branchial Cleft Cyst: A Potential Pitfall

Lateral cervical cystic mass in a young adult very rarely could be a first sign of an occult thyroid papillary microcarcinoma metastasis. In this paper, we presented a 37-year-old male patient whose preoperative 6 cm left lateral cervical cystic mass was initially diagnosed as branchial cleft cyst, but then the postoperative histopathological examination of the mass was revealed as papillary thyroid carcinoma metastasis. Preoperative fine needle aspiration biopsy was relevant with a branchial cleft cyst. In the left thyroid lobe there were 3 solid nodules with 4, 6, and 12 mm dimensions, respectively. One of the nodules had malignant well-differentiated cells diagnosed after fine needle aspiration biopsy. After total thyroidectomy, histopathologic evaluation of biopsy material's showed papillary thyroid microcarcinomas. This case indicates that especially in a young adult lateral cervical cystic mass should be carefully considered preoperatively for the possibility of metastatic occult thyroid carcinoma, especially for papillary carcinoma in differential diagnosis, and evaluation of the thyroid gland should be taken into account

Hydrolytic Behavior of Th4+, UO22+, and Ce3+ Ions at Various Temperatures

WOS: 000265073600004The hydrolytic behavior of Th4+, UO22+, and Ce3+ was investigated using the potentiometric method at elevated temperatures in KCl medium. For each metal ion, stability constants were obtained from the pH-metric data using the program HYPERQUAD2006. The formation of [Th(OH)](3+), [Th(OH)(2)](2+), [Th(OH)(3)](+), Th(OH)(4), [Th-4(OH)(8)](8+), and [Th-6(OH)(15)](9+) for the thorium ion, [UO2(OH)](+), [(UO2)(2)(OH)(2)](2+), [(UO2)(3)(OH)(4)](2+), and [(UO2)(3)(OH)(5)](+) for the uranyl ion, and [Ce-2(OH)](5+), [Ce-2(OH)(2)](4+), Ce(OH)(3), and [Ce-2(OH)(5)](+) for the cerium ion was taken into consideration. In addition, the effect of temperature on the stability constants was studied, and thermodynamic parameters were derived and discussed.Ege University Research FundEge University [2004 NBE 001]Financial Support is provided by Ege University Research Fund (contract no. 2004 NBE 001)

The effect of dentin desensitizers, and Nd:YAG laser pre-treatment on microtensile bond strength of self-adhesive resin cement to dentin

PURPOSE. The purpose of this study is to evaluate if pre-treatment with desensitizers have a negative effect on microtensile bond strength before cementing a restoration using recently introduced self-adhesive resin cement to dentin. MATERIALS AND METHODS. Thirty-five human molars' occlusal surfaces were ground to expose dentin; and were randomly grouped as (n=5); 1) Gluma-(Glutaraldehyde/HEMA) 2) Aqua-Prep F-(Fluoride), 3) Bisblock-(Oxalate), 4) Cervitec Plus-(Clorhexidine), 5) Smart protect-(Triclosan), 6) Nd:YAG laser, 7) No treatment (control). After applying the selected agent, RelyX U200 self-adhesive resin cement was used to bond composite resin blocks to dentin. All groups were subjected to thermocycling for 1000 cycles between 5-55 degrees C. Each bonded specimen was sectioned to microbars (6 mm X 1 mm X 1 mm) (n=20). Specimens were submitted to microtensile bond strength test at a crosshead speed of 0.5 mm/min. Kolmogorov-Smirnov, Levene's test, Kruskal Wallis One-way Analysis of Variance, and Conover's nonparametric statistical analysis were used (P.05). The microtensile bond strengths of Aqua-Prep F, and Cervitec Plus were similar to each other but significantly lower than the control group (P<.05). Bisblock showed the lowest microtensile bond strength among all groups (P<.001). Most groups showed adhesive failure. CONCLUSION. Within the limitation of this study, it is not recommended to use Aqua-prep F, Cervitec Plus and Bisblock on dentin when used with a self-adhesive resin cement due to the decrease they cause in bond strength. Beside, pre-treatment of dentin with Gluma, Smart protect, and Nd:YAG laser do not have a negative effect

Cerebral Venous Sinus Thrombosis With Internal Jugular Venous Thrombosis In A Male Patient With Nephrotic Syndrome

Cerebral venous sinus thrombosis with internal jugular vein thrombosis is not reported as a complication in nephrotic syndrome. We report a 40-year-old male with nephrotic syndrome, who had headache during his hospitalization. Conventional diagnostic tests showed extensive thrombosis at the proximal part of superior sagittal sinus, left cortical vein, left sigmoid-transverse sinus and left internal jugular vein. The patient underwent medical treatment and was discharged in good health after 2 weeks. The aim of this study is to report a novel case of cerebral venous sinus thrombosis with internal jugular venous thrombosis in a male patient with nephrotic syndrome.WoSScopu

In Vivo Investigation of Radiolabeled Bevacizumab in Healthy Rat Tissues

WOS: 000288378700010In this study, BevMab was conjugated with the bifunctional chelating agent [diethylenetriamine pentaacetic acid (DTPA)] and the product (BevMab-DTPA) was labeled with 99mTc using stannous chloride reducing method. The quality control studies of radiolabeled compound (99mTc-BevMab-DTPA) were done with Thin Layer Radio Chromatography (TLRC) and High Performance Liquid Radio Chromatography (HPLRC) methods (% 95 =) to confirm the labeling efficiency. High radiochemical yield [98.07 % +/- 2.17 (n = 13)] was obtained by TLRC method. Biodistribution studies of 99mTc labeled BevMab-DTPA was run on healthy female and male Albino Wistar rats. The distribution figures demonstrated that the radiolabeled compound was eliminated through the kidneys and accumulated in urinary bladder. The values of the BevMab-DTPA uptakes were similar in heart, blood, liver and spleen in both sexes.Ege UniversityEge University [2008 NBE 008]We thank to Resit Demir for editing the English language.

Trichobezoar in Vagina: Assessment for Child Sexual Abuse and Diagnostic Result of Forensic Science

Vaginal discharge and bleeding in children require a through and thoughtful evaluation to diagnose the underlying problem including infections, sexual abuse, and vaginal foreign bodies. We report a 6-year-old girl presenting with bloody vaginal discharge, carefully evaluated for sexual abuse, and finally diagnosed as a vaginal foreign body after vaginoscopy. A rolling hair ball was extracted from the vagina and was diagnosed as trichobezoar pathologically without any endo-ecto-mesodermal residual tissue. The hair ball was genetically detected and diagnosed to belong herself by containing no foreign structure. Child sexual abuse was ruled out by forensic interview at CAC and report of forensic science that reported genetic structure belonging to the child. Medicolegal assessment helped in final diagnosis to exclude child sexual abuse
