Dermatofibroma (DF) is a very common benign tumor, which occurs most often in middle-aged women. In general, DF presents as a solitary lesion on the extremities, shoulders or buttock, which occasionally develops following minor trauma or an insect bite. We describe a case of dermatofibroma involving the dorsum of right hand.

Ergotism can present with vascular, neurologic and gastrointestinal symptoms including gangrene in severe cases. In HIV, toxicity from interaction with protease inhibitors has been documented. We report case of a female who took cafergot for migraine resulting in absent peripheral pulses. She made a good recovery with steroids and pentoxyfilline

Creating anastomoses between the hollow organs of the abdominal cavity, abdominal formations of the retroperitoneal space and the jejunum always raises the question of preventing reflux from the jejunum into the drained cavity of the esophagus, stomach, gallbladder, external hepatic ducts, cysts of the liver and pancreas. After surgery, any reflux becomes pathological. Reflux is an obligate precancer. Thus, the reflux of bile and pancreatic juices in the stomach, the stump of the stomach and esophagus contributes to the occurrence of reflux esophagitis, reflux gastritis, ulcers and gastric cancer or its stump. After internal drainage of the cavity formation in the jejunum, postoperative reflux disease develops, which is caused by the actions of the surgeon who tried to help the patient sincerely. This allowed such states to be defined as “iatrogenic postoperative reflux disease”. The purpose of this work was to develop and introduce into practice the “plug” on the resulting loop of the jejunum, which does not migrate into the lumen of the intestine, with internal drainage of the hollow organs of the abdominal cavity and abdominal formations of the retroperitoneal space and evaluate the clinical results. As a result, the authors have developed a method for creating a “plug” on the jejunum loop, which is used for drainage, studies are being conducted on its safety, adequacy of functioning, general accessibility, and clinical situations are analyzed. For drainage of the abdominal formation impose a fistula between it and the jejunum loop 40–50 cm from the ligament of Treitz. We form an inter-intestinal fistula according to Brown, above which the length leading to a drained formation of the area of ??the jejunum is about 10 cm, in the middle of which we impose a “plug”. The length of the small intestine section which diverts from the drained formation to the inter-intestinal brown anastomosis is about 30 cm. To form a “plug”, we use the free area of ??the greater omentum, through which we perform a ligature of non-absorbable polypropylene material by vcol-vykola. The developed method of forming a "plug" does not cause abrupt ischemic changes in the area of ??operation, followed by necrosis of the intestinal wall and migration of the "plug" into the intestinal lumen, and its effectiveness has been proven using clinical observations, microcirculation studies, water test results and X-ray examination. The method of creating a "stub" is promising for the internal drainage of abdominal cavity formations and retroperitoneal space, for the formation of areflux nutrient eunostoma.

Lymphoedema is a chronic problem with various skin changes that lead to impaired care for the affected limb. These skin changes also lead to recurrent infections. The difficulty in care and the subsequent neglect leads to further spread of the infection and increased risk of future infections. Prevention of infections and prevention of progress of the skin changes is one of the main components of the treatment of the lymphoedema. There are various materials available to enhance the healing of the knobs and fissures secondary to lymphoedema. We would like to present our case report on the usage of chitosan in a patient with stage 7 skin changes of lymphedema.
