BACKGROUND: Pilonidal sinus (PS) disease of the sacrococcigeal region is an acquired condition resulting from penetration of shed hair shafts through the skin. Different types of operations have been described in the letterature. More recently fibrin glue has been used with succesfull. Aim of this study was to assess the effectiveness of fibrin glue for the treatment of pilonidal sinus. PATIENTS AND METHODS: Eight patients age ranged 21,8 +/- 6,5 affected by PS disease of sacrococcigeal region were included in this study. All patients undergoing surgical operation under local anaesthesia. Following administration of 1% methylene blue through the main opening, a small vertical elliptical incision is maked including the entire sinus opening and an excision of PS was performed without entering the sinus cavity, removing a minimal amount of subcutaneous tissue. Afterwards the highly concentrated fibrin glue, containing 1,000 U/ml of thrombin was applied to cover the wound. Post-operative pain, analgesic consumption, duration of hospital stay, failure healing, the rate and time of recurrence, time to healing, time to return to work and post-operative complications were recordered. RESULTS: All patients expressed satisfaction with the procedure. Mean hospital stay was 5.4 +/- 2.1 hours. Healing was achieved after 25.8 +/- 13.2 days. The post-operative pain mean score was 3.8 +/- 2.1 in first day, 2,9 +/- 1,8 in third day and 1,3 +/- 0,8 in the seventh day. The mean analgesic consumption per week was 5,6 +/- 3,2 medications. Mean time to return to work was 5,3 +/- 2,1 days. CONCLUSION: The minimal excision of PS and application of fibrin glue is a non-invasive effective treatment, easy and simple to performe and not associated to recurrences. For these reasons this procedure in our opinion as the first line treatment for pilonidal sinus disease.

Two cellular type, A and B cells, are evident in the intimal layer of the human synovial membrane. The Authors studied the B-cells that show in their cytoplasm some secretory granules that are still unknown. In the normal synovial membrane of human knee, with transmission electron microscopic techniques, the relationship between the B-cells and the blood capillary vessels and some morphological features of the secretory granules, are studied. The blood capillary vessels have a continuous cellular wall, surrounded by a basal membrane. Typical features of the B-cells are the marked development of the rough endoplasmic reticulum, the Golgi apparatus and dense secretory vesicles. The B-cells appear to constitute some specific secretory cells, but its function has yet to be determined.
