Effect of Recombinant Human Granulocyte/Macrophage Colony-Stimulating Factor on the Healing of Colonic Anastomosis in Rats

The purpose of this study was to investigate the efficacy of recombinant human granulocyte/macrophage colony-stimulating factor (rHuGM-CSF) on the wound healing of colonic anastomosis in rats. In total, 40 male Wistar rats were taken into this study. The control group (n = 20) received subcutaneous saline injection. The experiment group (n     

An aggressive and lethal course of Churg–Strauss syndrome with alveolar hemorrhage,intestinal perforation,cardiac failure and peripheral neuropathy

Churg–Strauss syndrome (CSS) is a rare type of necrotizing vasculitis affecting small to medium-sized vessels typically characterized by asthma, lung infiltrates, necrotizing granulomas and hypereosinophilia. Herein, we describe a case of CSS presenting severe and aggressive course. A 35-year-old male patient with weight loss, dyspepsia, dyspnea and hemoptysis was admitted. The laboratory analyses indicated a remarkable eosinophilia, elevated levels of serum total IgE and positive cANCA. Thorax CT findings were suggestive of alveolar hemorrhage. Bronchoalveolar lavage revealed alveolar hemorrhage with eosinophilia and transbronchial lung biopsy showed eosinophilic vasculitis. Cardiac enzymes were increased and murmurs were audible revealing cardiomyopathy proven by echocardiography. Pulse cyclophosphamide and methyl prednisolone was immediately started. On the 21st day, intestinal perforation developed and urgent surgery was performed. During a follow-up, although a radiological improvement was observed in the chest X-ray, cardiac failure, peripheral neuropathy and skin lesions developed and high-dose intravenous immunoglobulin and anti-TNF therapy (adalimumab) were applied. Despite the therapy, he died from heart failure and septicemia at 68th day of therapy.     

Primary leiomyosarcomas of the skin

We report four cases of cutaneous, and one of subcutaneous, leiomyosarcoma with the results of histological examinations and immunohistochemical studies. likelihood of metastases than the cutaneous type. Only one of our cutaneous leiomyosarcomas recurred after 18 months and the patient with a subcutaneous lesion had lung metastases after five years. Subcutaneous leiomyosarcomas have more
