Cigarette smoking intensifies tendinopathy of the LHBT. A microscopic study after arthroscopic treatment.

Smoking has a damaging effect on the musculoskeletal system, which was presented by authors in the rotator cuff and Achilles tendons studies; however, there are a lack of data about the effect of smoking on disorders of the long head of the biceps tendon (LHBT), particularly at the microscopic level. The purpose of this study was to investigate the effect of the tobacco smoking on the histopathologic alterations of the LHBT. Thirty-six patients with preoperatively diagnosed tendinopathy of the LHBT were referred to the Orthopaedics Department.

Process of neovascularisation compared with pain intensity in tendinopathy of the long head of the biceps brachii tendon associated with concomitant shoulder disorders, after arthroscopic treatment. Microscopic evaluation supported by immunohistochemical.

Background: Tendinopathy of the long head of the biceps brachii tendon (LHBT) is one of the most common, painful conditions of the anterior part of the shoulder and often coexists with rotator cuff tears. Multifactorial aetiopathology of tendi-nopathy is poorly understood; however, several studies indicated that it is seen predominantly in areas with decreased vascularity of the tissue; the pathology is also characterised by expansive and abundant neovascular in-growth. The aim of the study was to investigate the relationship between the neovascularisation of proximal part of the LHBT and pain along the bicipital groove.

Problems with diagnostic work-up of musculoskeletal pain due to glomus tumour. Four case reports.

Introduction: Glomus tumours are rare benign neoplasms of myoepithelial origin. Due to characteristic and painful symptoms, glomus tumours are a major clinical problem.

Material: Four histologically confirmed cases of glomangioma treated at the Orthopaedics & Traumatology Department between 1999 and 2007.

[Malignant fibrohistiocytoma of the larynx].

Introduction: Malignant fibrohistiocytoma is one of the rare neoplasms of the larynx. It has nonepithelial origin. The most common sites of the neoplasm are: limbs, trunk and retroperitoneal space.

[A case of giant-size mucoepidermoid carcinoma of parotid gland].

Introduction: A mucoepidermoid carcinoma is a rare disease of the salivary glands. It usually occurs as a small tumor (a few centimeters diameter). The most important diagnostic procedure for the treatment is a histological examination.

[Cervical sympathetic chain neurilemmoma--a case report].

Introduction: Neurilemmoma is benign, slowly growing tumour that arise from nerves. Cervical sympathetic chain neurilemmoma is rare. The majority of neurilemmomas are asymptomatic at the time of presentation.

[Plasmacytoma of the larynx].

Multiple myeloma is a neoplastic proliferation of the plasma cells of clonal character producing similar immunoglobulin or part of the immunoglobulin. Multiple myeloma occasionally occurs as solitary, extramedullary plasmacytoma. The location of plasmacytoma in the larynx is extremely rare.

Lymphangioma and lymphangiomyomatosis--the same lesion?

The authors present a very rare case observed in a 32 year old female with a huge tumor on the left side of the neck in which extensive changes characteristic for cystic lymphangioma in the lower part and for lymphangiomyomatosis in the upper part of the tumor were observed intraoperatively. On the basis of the discussed case the suggestion is put forward that these two rarely occurring diseases may have similar etiological grounds.

[Benign osteoblastoma of the frontal sinus].

The extremely rare case of benign osteoblastoma of frontal sinus was presented. Uncharacteristic clinical symptoms, radiological investigations and differentiation diagnostic were analysed. The operation treatment, which was chosen in that case, was described.

[Osteosarcoma of the sphenoid bone -- the cause of hemorrhage from the cavernous sinus].

A very rare of the osteosarcoma osteolythicum teleangiectaticum of the paranasal sinuses, treated surgically, is reported. The infiltration and destruction of the sphenoid bone caused a haemorrhage from the cavernous sinus. The difficulties in the preoperative evaluation of the extent of the osteosarcoma in the craniofacial bone structures are discussed.
