The prevalence of hyperprolactinaemia in overt and subclinical hypothyroidism

Abstract: The aims of this study were to: 1) determine the prevalence of hyperprolactinaemia in patients with newly diagnosed subclinical and overt hypothyroidism, and 2) investigate the change in PRL levels with treatment. In this observational study, patients with a new diagnosis of hypothyroidism in our endocrinology clinic were approached for participation, as were healthy controls. Patients with medical reasons for having elevated PRL levels, lactating and pregnant women were excluded from the study. No patient had kidney or liver disease. After examination to determine if clinical causes of PRL elevation were present, serum levels of thyrotropin (TSH), free thyroxine, free triiodothyronine and PRL were measured and correlation of PRL levels with the severity of hypothyroidism (overt or subclinical) was performed. Fifty-three patients (45 women, 8 men, mean age 45.3±12.2 years) had overt hypothyroidism. One hundred forty-seven patients (131 women, 16 men, mean age 42.9±12.6 years) had subclinical hypothyroidism. One hundred healthy persons (85 women, 15 men, mean age 43.9±11.4 years) participated as controls. The same blood tests were repeated in patients after normalization of TSH levels with L-thyroxine treatment. PRL elevation was found in 36% of patients with overt hypothyroidism, and in 22% of patients with subclinical hypothyroidism. PRL levels decreased to normal in all patients after thyroid functions normalized with L-thyroxine treatment. In the hypothyroid patients (overt and subclinical) a positive correlation was found between TSH and PRL levels (r=0.208, p=0.003). PRL regulation is altered in overt and subclinical hypothyroidism, and PRL levels normalize with appropriate L-thyroxine treatment.

Plastic detection comb better than visual screening for diagnosis of head louse infestation.

Abstract: Finding lice can be difficult in head louse infestation. We compared a new louse detection comb with visual inspection. All children in two rural Turkish schools were screened by the two methods. Those with lice were offered treatment and the results monitored by detection combing. Children with nits only were re-screened to identify latent infestations. Using visual inspection we found 214/461 children (46%) with nits but only 30 (6.5%) with live lice. In contrast detection combing found 96 (21%) with live lice, of whom 20 had no nits. Detection combing was 3.84 times more effective than visual inspection for finding live lice. Only 10/138 (7.2%) children with nits and no lice were found to have active infestation by day 16. We found that the detection comb is significantly (P<0.001) more effective than visual screening for diagnosis; that nits are not a good indicator of active infestation; and that treatment with 1% permethrin was 89.6% effective.

State and Trait Anxiety Scores of Patients Receiving Intravitreal Injections.

Abstract: Background To evaluate parameters on the state and trait anxiety scores of patients receiving intravitreal injections. Methods One hundred thirteen patients were included in the study. All subjects received intravitreal ranibizumab or bevacizumab injections. To measure the level of anxiety, Spielberg's State-Trait Anxiety Inventory questionnaire was used. Results The mean state anxiety scores were 45.19 ± 5.62 in experienced patients and 43.10 ± 6.62 in inexperienced patients (p = 0.078). The mean trait anxiety scores were 50.14 ± 6.62 in experienced patients and 49.17 ± 10.79 in inexperienced patients (p = 0.810). Additionally, there was no statistically significant difference in the state and trait anxiety scores between the male and female, employed, and retired patients (p > 0.05). Conclusion Anxiety may not show significant differences according to sociodemographic status. High anxiety scores found in this study also emphasize that health care providers should try to decrease anxiety levels during the course of treatment.

Approximate Analytical Solutions for Flow of a Third-Grade Fluid Through a Parallel-Plate Channel Filled with a Porous Medium

Abstract: The flow of a non-Newtonian fluid through a porous media in between two parallel plates at different temperatures is considered. The governing momentum equation of third-grade fluid with modified Darcy’s law and energy equation have been derived. Approximate analytical solutions of momentum and energy equations are obtained by using perturbation techniques. Constant viscosity, Reynold’s model viscosity, and Vogel’s model viscosity cases are treated separately. The criteria for validity of approximate solutions are derived. A numerical residual error analysis is performed for the solutions. Within the validity range, analytical and numerical solutions are in good agreement.
