    Objectives To measure the rate of Demodex folliculorum mite infestation in patients with type 2 diabetes mellitus and to investigate if it was related to blood glucose control. Methods Patients with type 2 diabetes were classified according to their glycosylated haemoglobin (HbA(1c)) level into two groups: a well controlled blood glucose group (HbA(1c)7%) and a poorly controlled blood glucose group (HbA(1c)>7%). A standardized skin surface biopsy method was used to determine if the patients had D. folliculorum infestation (>5 mites/cm(2) of skin). Results A total of 69 patients (38 female) were enrolled in the study. Seventeen (24.6%) patients had D. folliculorum infestation. There were no significant differences in age, sex or body mass index between patients with and without D. folliculorum infestations. A significantly higher proportion of patients with poor blood glucose control had D. folliculorum infestation compared with patients with well controlled blood glucose. Conclusions These current findings suggest that poor blood glucose regulation increases the susceptibility to D. folliculorum mite infestation in patients with type 2 diabetes.

    Aim: In this study, it was aimed to compare parasitological and cytological diagnostic methods to detect T. Vaginalis in samples taken from posterior fornix of vagina. Methods: In this cross-sectional study, study population (n= 104) were selected from women applying to gynecology outpatient clinic of Mustafa Kemal University Hospital with different complaints between March-August 2013. The presence of T. vaginalis was investigated by parasitological and cytological diagnostic methods. While direct microscopy, giemsa staining and culture in Cysteine-Peptone-Liver-Maltose medium (CPLM) were performed for parasitological diagnosis of T. vaginalis in samples taken from posterior fornix of vagina, cervical smear stained by Papanicolaou (PAPS) was used for cytological diagnosis. Results: T. vaginalis was detected in 12 (11.5%), 12 (11.5%), 14 (%13.4) of materials by direct microscopy, giemsa staining and culture, respectively. T. vaginalis was detected only 5 (4.8%) of materials by cytology. This difference was statistically significant (p<0.05). Conclusion: Our study results showed that parasitological methods are more sensitive than cytological methods in diagnosis of T. vaginalis. Therefore, T. vaginalis should be screened in women with non-specific symptoms in under developed countries where lack of periodic examination and polygamy were seen.

    Prevalence of Demodex folliculorum and Demodex brevis in the Eyelash Follicles of Healthy Subjects
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2012) Aycan-Kaya, Ozlem; Atambay, Metin; Daldal, Nilgun
    Demodex folliculorum and Demodex brevis mites are parasites of humans only. These mites are usually found on face, eyebrows, eyelashes and meibomian glands. When they appear in large numbers in eyelashe follicules, they may cause Demodex blepharitis. The aim of this study was to determine the prevalence of Demodex species on eyelashes of healthy individuals. Eyelashes were collected from 131 healty individuals who did not have a history of blepharitis. While D. folliculorum was detected in 17 (13.0%) people, D. brevis was only seen in four individuals (3.1%), the differences being statistically significant. It was observed that D. folliculorum occurs more commonly in older people and male/female rates were not different. Since the D. brevis was rarely found in eyelashes, cases of blepharitis are believed to be the result of the co-existance of D. brevis and D. folliculorum.
