Controversy On Prophylactic Oophorectomy, Utku Özcan, Didem Akyol, Selma Oransay, Murat Ekin, Tayfun Güngör, Oya Gökmen
Turkish Journal of Medical Sciences
The merits of prophylactic oophorectomy at the time of hysterectomy have been debated for many years. The most compelling argument for prophylactic removal of the ovaries has always been the prevention of ovarian cancer (2). Prophylactic oophorectomy has advantages and disadvantages. The actual incidence of cancer in retained ovaries is difficult to estimate. The advantages of prophylactic oophorectomy include the prevention of ovarian cancer, the alleviation of symptoms from residual ovary syndrome and the elimination of the need for reoperation for adnexal disease (2). Disadvantages include surgical castration, which results in the need for hormone replacement, and changes in self-image …

Turkish Journal of Medical Sciences
Imipenem, a very potent carbapenem derivative beta-lactam antibiotic, has recently found a major place in the treatment of antibiotic-resistant nosocomial infections. However, a convulsive side effect is seen in 0.2-3 percent of patients. Although it is suggested that this effect is due to the inhibition of gamma-aminobutyric acid (GABA) mediated inhibitory transmission, no study has been reported so far showing its effect on the cerebral cortex free inhibitory and excitatory amino acid levels. Twenty-one male TO albino mice were divided into three equal groups and given therapeutic (40 mg/kg/day) or excessive (500 mg/kg/day) doses of Imipenem/cilastatine (I/C) or saline solution …

Turkish Journal of Medical Sciences
Patient's rights primarily mean the practice of human rights and values in the field of health care services and include the rights which are considered as third generation rights. Recently, in many countries, especially in European countries, concept of health care services which give importance to patients' rights has been developed. Patients' rights in Turkey is one of the least known issues and remembered only by physicians' malparactises causing death or disabilities some of which are speculative. Efforts are needed to strengthen the patients' rights should be accelerated in order to protect the patients and physicians from unnecessary speculations in …
Mannoprotein Adhesin Of Candida Albicansgerm Tubes, Gülhan Vardar-Ünlü
Mannoprotein Adhesin Of Candida Albicansgerm Tubes, Gülhan Vardar-Ünlü
Turkish Journal of Medical Sciences
The production and detection of a mannoprotein adhesin (MPA) of the hyphal-form cells of C. albicans on plastic petri dishes was investigated. Using Concanavalin A-coated latex microspheres, the MPA was detected on the plastic surface on which C. albicans produced germ tubes. The adhesin was extracted using dithiothreitol and iodoacetamide. It did not inhibit the adhesion of the yeast-form C. albicans to buccal epithelial cells (BEC). This suggested that the MPA of the hyphal-form cells on the plastic was different from that on the yeast cells responsible for attachment to the BECs.

Although functional alterations in the central nervous system (CNS) and peripheral nerves are well documented in overt hypothyroidism, little is known about alterations of CNS in acute hypothyroidism. Sixteen patients with differentiated thyroid carcinoma were studied when prepared for radioiodine scanning after stopping levothyroxine (LT 4 ) therapy for 6 weeks to determine whether acute hypothyroidism leads to alteration in brainstem auditory evoked potentials (BAEPs). Repeat BAEPs were performed on the same patients at 6 months of the following L-T 4 therapy when patients were eu-thyroid. Neurophysiological findings were compared with a group of 20 normal controls with no hystory …
