Presentation of long-term results radiation treatment in patients with T1 glottic cancer and evaluation prognostic factors. We performed a retrospective analysis group 569 squamous cell carcinoma treated radiotherapy at the Center Oncology Cracow between 1977 2007. In all, 503 (88%) presented T1a stage disease 66 (12%) T1b. Anterior commissure infiltration was present 179 (31%) patients. Average hemoglobin level prior to therapy 13.9 g/dl. Using body mass index (BMI), 114 (20%) were...

We have recently presented an integrated silicon-glass opto-chemical sensor forlab-on-chip applications, based on porous silicon and anodic bonding technologies. In thiswork, we optically characterized the response exposure to vapors of severalorganic compounds by means reflectivity measurements. The interaction between theporous silicon, which acts as transducer layer, organic fluxed into glasssealed microchamber, is preserved fabrication process, resulting in optical pathincrease, due...

Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% cases after first-time dislocation. In most patellar dislocation, medial patellofemoral ligament (MPFL) becomes damaged. Between 2010 and 2012, 33 children adolescents (39 knees) with recurrent were treated MPFL reconstruction using adductor magnus tendon. The aim our study to assess effectiveness this surgical procedure. outcomes evaluated functionally (Lysholm knee scale, Kujala Anterior Knee...

The efficiency of treating simple bone cyst (SBC) is low. Depending on the choice treatment, a positive response occurs in 20 to 80 % cases. These rates are unacceptable, particularly considering they concern treatment benign lesions affecting children. Although curettage one first known ways SBC, no precise qualification criteria exists for this procedure. aim our study identify which type may be most effectively treated using with grafting. A retrospective analysis was performed 24...

Abstract In this communication, the design and fabrication of a silicon‐glass microsystem for lab‐on‐chip sensing applications have been reported. Each component has realised using wet etch process porous silicon (PSi) technology, while final device obtained intimately joining all elements by Anodic Bonding (AB) process. The flow injection analysis (FIA) principle adopted in microfluidic manipulation analyte samples: very small volume substances can be quickly repeatedly monitored....

Abstract Background Biomechanical studies indicate that during outward rotation of the tibia and valgus knee joint position, patella is shifted in lateral direction. After first-time patellar dislocation, dynamic position femur relation to plays an important role stability, because medial stabilizer (mostly MPFL) damaged or inefficient. The most factor controlling rotational movement thigh are hamstring muscles. aim study therefore determine whether patients with instability have a...

Infection with HPV16 in cancers of the oral cavity (OCSCC) and oropharynx (OPSCC) is, today, an important etiological prognostic factor. Patients HPV-positive OPSCC have a better prognosis than uninfected patients. However, over 40% these patients, cancer progression is noticed. Their identification particularly due to ongoing clinical trials regarding possibility de-escalation anticancer treatment patients OPSCC. Some studies suggest that there differentiate HPV16-positive by STING...
