Case report: A unique pediatric case of a primary CD8 expressing ALK-1 positive anaplastic large cell lymphoma of skeletal muscle.

Primary involvement of skeletal muscle is a very rare event in ALK-1 positive anaplastic large cell lymphoma (ALCL). We describe a case of a 10-year old boy presenting with a three week history of pain and a palpable firm swelling at the dorsal aspect of the left thigh. Histological examination of the lesion revealed a tumoral and diffuse polymorphic infiltration of the muscle by large lymphoid cells.

One-Year Clinical and Radiological Results of a Prospective, Investigator-Initiated Trial Examining a Novel, Purely Autologous 3-Dimensional Autologous Chondrocyte Transplantation Product in the Knee.

Background: The 3-dimensional autologous chondrocyte transplantation (ACT3D) comprises isolation of chondrocytes from cartilage biopsies, cultivation to spheroids, and transplantation into the cartilage defect.

Objectives: To evaluate the patients' general health and functionality and to assess the defect repair after ACT3D with spheroids by MRI and MOCART scoring.

Methods: Thirty-seven patients with isolated chondral lesions of the knee underwent ACT3D with spheroids through medial arthrotomy.

Effects of a clinical pathway of pulmonary lobectomy and bilobectomy on quality and cost of care.

Purpose: This study evaluates medical and economic effects of a clinical pathway (CP) for open lobectomy and bilobectomy with respect to process quality, outcome quality, and hospital cost.

Methods: We compared 38 consecutive patients who underwent open lobectomy or bilobectomy between April 2007 and June 2008 and were treated with a CP (CP group) with 43 consecutive patients treated without CP between 2005 and 2007 (pre-pathway group). Indicators for process quality were duration of catheter placement, pain intensity, respiratory exercising, and mobilization.

Pulmonary epithelioid hemangioendothelioma: report of three cases.

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor of low-grade malignancy, the prognosis of which remains unpredictable. Surgical and/or chemotherapeutic options have to be evaluated depending on intrathoracic tumor spread and systemic metastases. Three cases of PEH with both clinical and pathological findings are herein summarized and the relevant current literature discussed.

Elevated risk of squamous-cell carcinoma of the lung in heavy smokers carrying the variant alleles of the TP53 Arg72Pro and p21 Ser31Arg polymorphisms.

Alterations in cell cycle regulation and apoptosis leading to malignant transformation could be caused by common genetic variants in tumor suppressor genes. The effects of the TP53 polymorphism Arg72Pro on lung cancer risk have been investigated in numerous studies with, however, conflicting results. In many studies, important risk modifiers such as smoking or tumor histology were not taken into account.

Specific combinations of DNA repair gene variants and increased risk for non-small cell lung cancer.

Several polymorphisms in DNA repair genes have been reported to be associated with lung cancer risk including XPA (-4G/A), XPD (Lys751Gln and Asp312Asn), XRCC1 (Arg399Gln), APE1 (Asp148Glu) and XRCC3 (Thr241Met). As there is little information on the combined effects of these variants, polymorphisms were analyzed in a case-control study including 463 lung cancer cases [among them 204 adenocarcinoma and 212 squamous cell carcinoma (SCC)] and 460 tumor-free hospital controls. Odds ratios (OR) adjusted for age, gender, smoking and occupational exposure were calculated for the variants alone and combinations thereof.
