Unusual case of mixed form of femoroacetabular impingement combined with nonspecific synovitis of the hip joint in a young adult-- A case report.

Introduction: Minimal bone changes in the acetabulum and/or proximal femur, through mechanism known as femoroacetabular impingement, during flexion, adduction and internal rotation lead to early contact between femoral head-neck junction and acetabular brim, in anterosuperior region. Each additional pathological substrate which further decreases specified clearance provokes earlier onset of femoroacetabular impingement symptoms.

Case Report: We presented a 20-year-old male patient with groin pain, limping, positive impingement test, radiological signs of mixed form of femoroacetabular impingement and unrecognized chronic hypertrophic synovitis with earlier development of clinical hip symptoms than it has been expected.

Non-functional parathyroid cyst--diagnostic pitfall: A case-report.

Introduction: Parathyroid cysts are relative rare and they may be misdiagnosed with thyroid nodules. Parathyroid cysts are characterized by elevated level of parathyroid hormone (PTH) in cystic fluid. CASE REPORT.

Surgical dislocation of the hip in patients with femoroacetabular impingement: Surgical techniques and our experience.

Background/aim: Arthrosis of the hip is the most common cause of a hip joint disorders. The aim of this study was to present our experience in the application of a safe surgical dislocation of the hip in patients with minor morphological changes in the hip joint, which, through the mechanism of femoroacetabular impingement, cause damage to the acetabular labrum and adjacent cartilage as an early sign of the hip arthrosis.

Methods: We have operated 51 patients with different morphological bone changes in the hip area and resultant soft tissue damage of the acetabular labrum and its adjacent cartilage.

Early clinical results of surgical treatment of patients with femoroacetabular impingement.

Introduction: Surgical treatment is the treatment of choice in patients with symptoms and radiological signs of femoroacetabular impingement.

Objective: Our experience and early results of surgical treatment of patients with signs of femoroacetabular impingement and early hip osteoarthritis are reported.

Methods: The results of treatment of 21 patients aged 23-54 years with different types of femoroacetabular impingement are presented.

Contribution to the method for determining femoral neck axis.

Introduction: Femoral neck axis plotting is of great significance in measuring parameters that define femoral head-neck junction sphericity in the group of patients with the femoroacetabular impingement. Literature methods of femoral neck axis determination have weaknesses associated with the risk of obtaining inaccurate values of certain parameters.

Objective: Method of plotting of the femoral neck axis by two parallel lines that belong to the medial quarter of the femoral neck is proposed.

Measuring the osteochondral connection of the femoral head and neck in patients with impingement femoroacetabular by determining the angle of 2alpha in lateral and anteroposterior hip radiographic images.

Background/aim: Femoroacetabular impingement, a pathophysiological mechanism of small morphological changes of the hip leads to early arthritic changes. The aim of this study was to present a simple method for the quantification of femoral head and neck junction in patients with cam form of femoroacetabular impingement, in standardized anteroposterior and profile DUNN 90 radiograms of the hips.

Methods: In standardized anteroposterior and profile DUNN 90 images of the hips we determined the angle of 2 alpha, defined by our own original method.

Possibilities of nontoxic autonomous thyroid nodules treatment by percutaneous ethanol injection.

Background/aim: According to the current principles, autonomous functional thyroid nodules are treated by surgery or by radioiodin therapy. Ultrasound guided percutaneous ethanol injection into solid tumors of the soft tissues was a starting point in attempts to treat the thyroid nodules by the same method. The aim of the study was to assess the efficiency of percutaneous injection in treating solitary, nontoxic, autonomous thyroid nodules of up to 15 mL volume.

[Thyrocyte morphomethric analysis significance in differential diagnosis of thyroid carcinoma].

Unlabelled: BACKGRAUND/AIM: Conventional cytomorphology of thyroid cell aspirates is limited in preoperative differential diagnosis of follicular adenomas (FA) and hyperplastic adenomatoid nodular goiters from well differentiated thyroid follicular carcinoma (FTC) and follicular variant of thyroid papillary carcinoma (PTC). This is the reason of inaccurate presurgical differential diagnosis and in the same cases of inadequate operative managament. The aim of the study was to evaluate the role of quantitative estimation of thyreocite nuclear features (cariomorphometry) in thyroid aspirated smears in preoperative differential diagnosis of benign from malignant thyroid lesions.

A New PC and LabVIEW Package Based System for Electrochemical Investigations.

The paper describes a new PC and LabVIEW software package based system forelectrochemical research. An overview of well known electrochemical methods, such aspotential measurements, galvanostatic and potentiostatic method, cyclic voltammetry andEIS is given. Electrochemical impedance spectroscopy has been adapted for systemscontaining large capacitances.

[The von Hippel-Lindau syndrome with pheochromocytoma].

The members of four generations of a family with Von Hippel-Lindau syndrome (VHL) have been followed by one of us (I.P.) for 30 years.

[Personal experience in diagnosis and localization of pheochromocytoma].

Introduction: Pheochromocytomas are most commonly tumours of adrenal medullary origin. Pheochromocytoma by definition produces and secretes catecholamines. Similar tumours that do not secrete active substances of any kind are called non functioning paragangliomas.
