Background: Massive gastrointestinal bleeding in children is uncommon. Dieulafoy lesion is an uncommon disease which may lead to massive and repeated upper gastrointestinal hemorrhage. We report two cases of gastric Dieulafoy lesion successfully treated with either band ligation or endoscopic hemoclipping. CASE PRESENTATION: First case report: A previously healthy 18-month-old female infant with E. coli sepsis, pneumonia and respiratory failure with bilateral pneumothorax requiring chest drainage.

Background: Breast cancer is the most frequent neoplasm in women. Axillary lymph nodes dissection represents the treatment of choice in locally advanced breast cancer for prognostic and curative purposes. Seroma formation, an abnormal collection of fluid in the dead space of the axilla, is described in Literature with a wide range of incidence (3-85%). It is a source of significant morbidity and discomfort.

The pharmacodynamic effects of various combined oral estrogen-progestin combinations (COC) are examined for their components alone or in the various combined formulations. Special emphasis is given to products containing natural estrogens. Areas covered: Recent information on the effect of androgens, estrogens, progestins, as well as various COC combinations on the coagulation cascade will be reviewed aiming at providing an updated picture.

Blood-feeding animals are known for their ability to produce bioactive compounds to impair haemostasis and suppress pain perception in the host. These compounds are extremely appealing for pharmacological development since they are generally very effective and specific for their molecular target. A preliminary RNA-Seq based characterization of the secretion from salivary and mid-oesophageal tissues of the vampire snail Cumia reticulata, revealed a complex mixture of feeding-related transcripts with potential anaesthetic and anticoagulant action.
