Abstract Objects:Giant cell tumor of bone (GCTB) isa locally aggressive lesion with unpredictable behavior. Here, we aim to evaluate the epidemiological characteristics, clinical and functional outcome of GCTB in a relatively large series of patients. Methods:Patients with the diagnosis of GCTB were included in this retrospective study.Surgical options included extended curettage wh...

Feeding kinematics, suction and hydraulic jetting capabilities of bearded seals (Erignathus barbatus) were characterized during controlled feeding trials. Feeding trials were conducted both on land and in water, and allowed a choice between suction and biting, but food was also presented that could be ingested by suction alone. Four feeding phases, preparatory, jaw opening, hyoid depression and...

BACKGROUND The pharmacological management of early pregnancy loss reduced substantially the need for dilation and curettage. However, prognostic markers of successful outcome were not established. Thus the major purpose of this study was to determine the sensitivity and specificity of the uterine artery pulsatility (PI) and resistance (RI) indices to detect early pregnancy loss patients requiri...

BACKGROUND/AIMS To determine whether topical 2% lignocaine (lidocaine) gel is an effective anaesthetic agent for chalazion surgery. METHODS In a randomised controlled clinical trial, 57 subjects aged 12 years or over requiring incision and curettage for chalazion were recruited over an 8 month period. Patients were randomised into two groups. One group received 1.5 ml of lignocaine 2% injecti...

CONTEXT AND OBJECTIVE Recent studies have indicated that vitiligo areas contain inactive or dormant melanocytes. Melanin synthesis is related to tyrosinase presence and indicative of active metabolic state. The aim of this study was to compare repigmentation, epidermal melanocyte distribution and tyrosinase mRNA detection through reverse transcriptase polymerase chain reaction, in tissue sample...

Chondroblastoma of the patella is rare. Aneurysmal bone cysts, which develop from a prior lesion such as a chondroblastoma, are seldom seen in the patella. The authors report a case of a 36-year-old man who presented with 2 years of right knee pain without calor, erythema, pain on palpation, or abnormal range of motion. Radiological studies suggested aneurysmal bone cyst. The lesion was excised...

The aim of our study was to assess the efficacy and safety of endoscopic coblator adenoidectomy compared to cold curettage in paediatric patients. Forty homogeneous children (4-16 years of age) with adenoid hypertrophy were divided in 2 groups to receive adenoidectomy using cold curettage (A) or coblator (B). After surgery the following outcomes were evaluated: pain score on first day, days rep...

BACKGROUND AND PURPOSE The natural pattern of bone healing in large bony defects following curettage alone as treatment of benign bone tumors around the knee is not well reported. We analyzed the outcome in 146 patients. PATIENTS AND METHODS 146 patients with over 18 months of follow-up who underwent curettage without bone substitute filling or bone grafting for a benign tumor in the distal f...

abstract background: accumulation of secretions in the airways of patients with an endotracheal tube and mechanical ventilation will have serious consequences. one of the most common methods of airway clearance is endotracheal suctioning. in order to facilitate discharge of airway secretion resulting in promotion of gas exchange, chest physiotherapy techniques can be used at the time of expirat...

This paper numerically investigates the effectiveness of the control of steady suction on a stationary circular cylinder with several isolated suction holes on the surface at a subcritical Reynolds number. The control effectiveness as a function of the azimuthal position, spanwise spacing and suction flow rate of the suction holes on the control of the aerodynamic forces on the cylinder and the...
