Treatment of rapidly proliferating haemangiomas in newborns with propranolol and review of the literature.

Aim: Infantile haemangiomas (IH) are neoplastic proliferations of endothelial cells which occur with an incidence of 10-12%. IH rapidly growing and found in cosmetically sensitive areas or complicated with ulcerations are of special concern of parents.

Methods: A review of medical charts was performed for newborns treated with propranolol because of IH between 2012 and 2013.

Treatment of problematic infantile hemangiomas with propranolol: a series of 40 cases and review of the literature.

Unlabelled: Infantile hemangiomas (IH) are neoplastic proliferations of endothelial cells which occur with an incidence of 10 to 12% within the first year of life. IH grow after birth and usually regress spontaneously, but still can lead to deformities when they are located in the facial areas of the lip, eyelid, nasal tip or the ear. We wanted to share our experience in the treatment of problematic IH with propranolol.

Anti-Müllerian hormone levels in serum 1 year after unilateral orchiopexy.

The aim of this study was to determine the serum anti-Müllerian hormone (AMH levels) in a group of boys with cryptorchidism before and 1 year after surgery. Additionally, the effect of orchiopexy, based on the testicular position and morphology, was evaluated. Fifty boys who were 1-4 years old (median, 2.

Expression of estrogen receptors α and β in paratesticular tissues in boys operated on for unilateral cryptorchidism between the 1st and 4th years of life.

Background: The aim of this study was to assess the expression of estrogen receptors alpha and beta in paratesticular tissues in a group of boys with and without cryptorchidism, and evaluation of karyotypes, localization, morphology and the major length of the undescended testes.

Material/methods: Fifty boys (1-4 years old) with unilateral cryptorchidism were evaluated. Fifty healthy boys within the same age range, with inguinal hernia, served as a control group.

Serum AMH concentration as a marker evaluating gonadal function in boys operated on for unilateral cryptorchidism between 1st and 4th year of life.

The aim of this study was to measure the serum AMH (anti-Mullerian hormone) concentrations in a group of boys with or without cryptorchidism, evaluation of karyotypes, testicular position, morphology, and major length of the undescended testes. Fifty boys who were 1-4 years old (median = 2.4 years) with unilateral cryptorchidism were evaluated.

Peritoneal cell response during adhesion formation.

Background: We estimated a number of cell populations of peritoneal fluid in rats with experimentally developed peritoneal adhesions.

Materials And Methods: The fluid was taken in standarized conditions at the first operation and during reoperation. Animals were divided into four groups.

Mast cells in peritoneal fluid in rats with experimentally induced peritoneal adhesions.

Mast cells (MC) produce, store and release many biologically active substances, especially inflammatory factors, chemotactic substances for neutrophiles, cytokines and prostaglandins. They play very important role in fibrinosis and they are an important factor in peritoneal adhesions formation and lysis. In this study we tried to evaluate role of mast cells in peritoneal adhesions formation.

Topography and morphometry of intestinal mast cells in children with Hirschsprung's disease.

Mast cells (MC) are source of many biological active compounds like cytokines, arachidonic acid derivates, proteoglicanes, prostaglandins, proteases, free oxygen radials, NGF, PAF and many more. The role of MC in pathogenesis of Hirschsprung's disease (HD) is not clear. Substances produced by MC may exert an important effect on embryology, growth, differentiation and regeneration of intestinal nervous system.

Use of synaptophysin immunohistochemistry in intestinal motility disorders.

The purpose of this study was to describe synaptophysin (SY) immunoreactivity in colonic specimens from patients with Hirschsprung's disease (HD), chronic constipation (CC), or anal atresia (AA). This membrane protein is specific for the synaptic vesicles in the central and peripheral nervous system and responsible for neurotransmission. Biopsy specimens of the intestinal wall were obtained from 18 patients (age range, 2 days to 7 years).

Oxyuriasis-induced intestinal obstruction in a child--case report.

Purpose: The presentation of an unusual case of the tumor of ileum wall induced by pinworm infection in a 5-years-old child.

Material And Methods: The record of a 4-years-old boy treated in the department of pediatric surgery was analyzed concerning the diagnostic difficulties. After 6 month from an episode of ileo-cecal intusussception successfully treated with a barium colon enema, the diagnosis of lymphoma was made and the resection of distant segment of small intestine was performed.

Suitability of selected markers for identification of elements of the Intestinal Nervous System (INS).

The possibility of identifying and characterising elements of the enteric nervous system based on their contents of cathepsin D, chromogranin A, neuronal specific enolase and S-100 protein was studied in colorectal specimens (operative full-thickness, seromuscular and mucosomuscular biopsies) obtained from 15 children, aged 2 days to 10 years. Nine patients suffered from Hirschsprung's disease, and two from chronic constipation. Four neonates with imperforate anus or meconium ileus composed the control group.

Gastric mucosal exposure to histamine in rats is followed by absorption of histamine but not mucosal hyperemia.

Background/aims: Superficial mucosal damage is associated with mucosal hyperemia and release of histamine into venous blood and gastric lumen. This study was designed to examine if histamine administrated directly to gastric mucosa becomes absorbed and transported away with blood, and if so whether it is capable of increasing gastric mucosal blood flow.

Methodology: Superficial mucosal injury was induced by exposing chambered rat stomachs to 2 M NaCl for 10 min, and 45 min later 4.

Hemorrhagic shock-induced changes in the cathepsin D activity in the intestinal wall and blood serum in rats.

Hemorrhagic shock causes release of lysosomal proteolytic enzymes which contribute to intestinal wall destruction and can be moved into the circulation as well as into the gut lumen. The aim of the study was to examine the activity of cathepsin D in relation to the intestinal wall injury after 60 minutes of untreated hemorrhagic shock in rats. The total cathepsin D activity was investigated in duodenum, jejunum, ileum, cecum and colon, as well as in systemic and mesenteric blood serum, and the biochemical results were compared with morphological changes in the respective segments including immunohistochemical expression of cathepsin D.

Cathepsin D activity in the intestinal wall in experimental untreated hemorrhagic shock.

The total cathepsin D activities in the intestinal wall and in venous mesenteric and arterial systemic blood were investigated on the rats in untreated hemorrhagic shock lasting 60 minutes. We observed a decrease in cathepsin D activity in homogenates of respective segments of small and large bowels and an increase in the enzyme activity in blood serum of both origin. The shock resulted in lowering protein concentration in the intestinal wall and its increase in the mesenteric blood.
