Treatment of acne with intermittent and conventional isotretinoin: a randomized, controlled multicenter study.

Oral isotretinoin is the most effective choice in the treatment of severe acne. Application of isotretionin to acne has been expanded to treat those patients with less severe but scarring acne who are responding unsatisfactorily to conventional therapies. However, its use is associated with many side effects, some of which can result in very disastrous consequences.

The effect of tibolone versus 17beta-estradiol on climacteric symptoms in women with surgical menopause: a randomized, cross-over study.

Objective: To compare the effectiveness of tibolone and 17beta-estradiol on climacteric symptoms, in a randomized, single-blind, cross-over study in surgically menopausal women.

Material And Methods: Forty surgically menopausal women were divided randomly into two groups. Group A received treatment with tibolone for 6 months, while group B received 17beta-estradiol.

[Spinal anesthesia in cesarean section with different combinations of bupivacaine and fentanyl].

The use of opioids for spinal anesthesia increases the anesthetic quality, reduces side effects and also has advantages for the postoperative analgesia. The aim of this study was to evaluate the effects of subarachnoid %0.5 hyperbaric bupivacaine (B) alone or combined with 10 or 20 mg fentanyl (F) on the anesthetic properties for cesarean section and newborn.

New concepts of the management of one-lung ventilation.

Purpose Of Review: Hypoxemia is considered to be the most important challenge during one-lung ventilation. Recent studies, however, have shown that one-lung ventilation can involve some lung damage and can therefore be per se a cause of hypoxemia.

Recent Findings: It has been shown that some parameters of one-lung ventilation are associated with an increased probability of lung injury.

BIS guided sedation with propofol during spinal anaesthesia: influence of anaesthetic level on sedation requirement.

Background: In this prospective, clinical study we tested the hypothesis whether two different doses of spinal administered bupivacaine and accordingly, two different levels of spinal anaesthesia can affect the dose requirement of propofol during BIS guided sedation.

Methods: Fifty women undergoing vaginal hysterectomy (high spinal group, HS) or transvaginal tape (TVT) procedure for urinary incontinence (low spinal group, LS) under spinal anaesthesia were enrolled to the study. In group HS, 17.

Assessment of the success of cardiopulmonary resuscitation attempts performed in a Turkish university hospital.

The success rate of cardiopulmonary resuscitation (CPR) may differ from institution to institution, even within different sites in the same institution. A variety of factors may influence the outcome. In this study, we assessed the adequacy of CPR attempts guided by the current standards and aimed to define the factors influencing the outcome following in-hospital cardiac arrest.

Audio-vestibular disturbances in Behcet's patients: report of 62 cases.

Unlabelled: This study was carried out to determine the characteristics and incidence of hearing loss and vestibular disturbance in Behcet's syndrome with a large number of patients. Sixty-two patients with Behcet's syndrome were included in this study, 34 men and 28 women whose mean age was 33.7 (15-60).

Comparison of early postoperative results of thymectomy: partial sternotomy vs. videothoracoscopy.

Background: The aim of this study was to compare the early postoperative results of thymectomy operations after partial sternotomy and videothoracoscopy for myasthenia gravis.

Methods: A total of 51 thymectomy operations were reviewed. The surgical procedure was simple thymectomy with partial sternotomy in the first 19 patients (Group I) and videothoracoscopic thymectomy (Group II) in the remaining patients.

Objective: To determine the effectiveness of postoperative local anesthesia in tonsillectomy patients using an intra-individual study design.

Methods: Thirty patients aged 5-15 were included in a prospective study. Patients received a local infiltration of 0.

Castleman's disease as an unusual neck mass: case report.

Castleman's disease is a rare, benign disease of unknown cause that induces reactive lymph node hyperplasia, most commonly in the mediastinum. It has 2 histologic subtypes: hyaline vascular and plasma cellular. A definitive diagnosis necessitates tissue biopsy.

Vascular reconstruction in Buerger's disease: is it feasible?

Purpose: Thromboangiitis obliterans (Buerger's disease) is a clinical syndrome characterized by segmental occlusions of the distal vessels. Although a cessation of using nicotine products usually helps, nevertheless a surgical revascularization may be needed in cases of stage III and IV limbs. Because of the distal and segmental nature of the disease, these procedures are rarely feasible.
