Abstract
Due to global warming, animals are experiencing heat stress (HS), affecting many organic functions and species' survival. In this line, some characteristics of immune cells in sea urchins subjected to short-term HS were evaluated. Paracentrotus lividus adult females were randomly divided into three groups and housed in tanks at 17 °C. In two of these tanks, the temperatures were gradually increased up to 23 and 28 °C. Celomatic fluid was collected after 3 and 7 days. The coelomocytes were morphologically typed and evaluated for their mitochondrial membrane potential (MMP), lipoperoxidation extent (LPO), and hydrogen peroxide content (H2O2). Respiratory burst was induced by treatment with phorbol 12-myristate 13-acetate (PMA). HS caused a significant change in the coelomocytes' type distribution. MMP increased in the 23 °C-group and decreased in the 28 °C-group at both 3 and 7 days. LPO only increased in the 28 °C-group at 7 days. H2O2 progressively decreased together with the temperature increase. Respiratory burst was detected in all groups, but it was higher in the 17 °C group. In conclusion, the increase in temperature above the comfort zone for this animal species affects their immune cells with possible impairment of their functions.

Abstract
PURPOSE Traumatic diaphragm rupture (TDR) is a rare complication of trauma in pediatric age and may be easily missed by the severity of associated injuries so that delayed emergent presentation can occur with increased rate of morbidity and mortality. No review has been available to guide clinicians through the pitfalls and the initial diagnostic approach to pediatric TDR. METHODS A Medline thorough search on TDR was conducted using different queries. English language citations were identified during the period of January 2000 through December 2014 limiting the search to pediatric age (0-18 years). Abstracts were reviewed to determine eligibility and texts were obtained for further review. Differences were resolved by consensus and only reliable data were included. RESULTS Most frequently reported presenting symptoms of TDR are respiratory and abdominal. While respiratory symptoms are among the most frequently described at the onset in pediatric and adult series, abdominal symptoms result to be more frequent in adult than pediatric patients. Chest X-ray (CXR) is the first-line imaging exam which is reported to show pathognomonic or suspect findings in 85 %. CT was the second main radiological technique used, in particular to confirm the suspicion of TDR. CONCLUSIONS A high clinical index of suspicion is needed to diagnose and effectively manage diaphragmatic rupture. TDR should be kept in mind while dealing with patients assessed for abdominal or respiratory symptoms whenever there is history of trauma or blunt injury especially in children as the increasing of non-operative management of blunt abdominal trauma could result in missing important injuries as TDR.

Abstract
Dapsone has been shown to be effective in treating immune thrombocytopenic purpura (ITP) in adults. In children the experience is limited. We describe our experience using dapsone in a female with refractory, symptomatic ITP who suffered intracranic haemorrhage and massive gastric bleeding. After treatment platelet counts was more than 100 x 103/μL, and reached 1000x103/μL. Discontinuation resulted in a rapid decrease in platelet counts, with severe intracranial haemorrhage (ICH). The recovery of dapsone led the platelets count to lower values. We suggest that treatment should not be discontinued in responders, at least in children with symptomatic ITP. Additional studies of dapsone in children are warranted.

Abstract
AIMS The aim of study was to assess, by means of perineal ultrasound (US), women treated with the trans-obturator suburethral sling procedure for urinary stress incontinence (USI). METHODS Twelve women with USI and urethral hypermobility were enrolled. Static and dynamic perineal US of urethral mobility was performed before and after tension-free vaginal tape opturator (TVT-O) procedure: US parameters evaluated were pubis-urethra distance and inclination angle of the urethral axis. RESULTS The Valsalva stress US evaluation showed a return to normal range of the pubic urethral distance in all cases (p = 0.0001); also a correction of the angle of inclination of the urethral axis occurred in all patients (p < 0.0001). CONCLUSIONS Our results propose the use of perineal US for patients with USI as an additional diagnostic tool and a means for postsurgical follow-up.

Abstract
A rare embryonal brain tumor has been diagnosed in a 4-year-old boy. The mass, located at the pons and mesencephalon, has been histologically classified as an embryonal tumor containing abundant neuropil and true rosettes. After surgical complete removal of the neoplasia, the child received intensive combined chemotherapy and radiotherapy. He is alive and free of disease at 34 months from surgery. Difficulties in histological definition, possible suggestions for treatment proposals are discussed.

Abstract
BACKGROUND & AIMS The yeast Hansenula anomala has been associated with gastrointestinal symptomatology and damage to the intestinal wall in humans. In vitro and in vivo, H. anomala secretes a toxin, killer toxin, which is lethal to other microorganisms. In view of the very high rate of killer phenotype expression recorded for H. anomala strains in nature, this study aimed to investigate the hypothesis that H. anomala killer toxin plays a role in the pathogenesis of H. anomala-induced enteritis. METHODS Effects of active and heat-inactivated H. anomala killer toxin on intestinal fluid homeostasis and electrolyte balance were investigated in rat small intestine using a standard intestinal perfusion technique. Sections of the perfused jejunum tracts were examined histologically. RESULTS H. anomala killer toxin induced a significant secretion of water and electrolytes. No significant change was observed when either heat-inactivated H. anomala killer toxin or control growth medium were tested. Histological analysis showed ischemic degeneration of villi and sloughing of surface epithelium in 50% of active H. anomala killer toxin-perfused jejuna. CONCLUSIONS This paper presents original observations compatible with the hypothesis that H. anomala killer toxin plays a role in the pathogenesis of H. anomala-induced enteritis.

Abstract
BACKGROUND/AIMS Little information is available on the role of colon during small intestinal secretion. The aim of this study was to examine the effects of secretory changes in the small intestine on the colonic transport of electrolytes and water in vivo. METHODS The jejunum and colon of the rat were perfused in vivo simultaneously but separately, and jejunal secretion was induced by exposing the jejunum to cholera toxin, 8-bromo-cyclic guanosine monophosphate, or hyperosmolarity. RESULTS Jejunal perfusion with a hyperosmolar mannitol solution (600 mOsm/L) or with 8-bromo-cyclic guanosine monophosphate (0.5 mmol/L) resulted in net secretion of water in the jejunum but did not affect the baseline rate of water transport in the colon. On the contrary, addition of cholera toxin (1 microgram/loop) to the jejunal segment not only induced a significant local secretory change but also resulted in a similar change in the colon, which was not exposed to cholera toxin. The intestine was transected immediately below the jejunum, thus interrupting the anatomical continuity of the enteric nervous system. This procedure eliminated the distant secretory effect of cholera toxin, thus allowing the conclusion that the enteric nervous system is involved in the distant propagation of the local secretion induced by cholera toxin. CONCLUSIONS Cholera toxin, but not other secretagogues, triggers a secretory response that is not only local but also extends to distal segments via the enteric nervous system.

Abstract
Conflicting data have been published in favor of or against a secretory effect of atrial natriuretic peptide (ANP) in the intestine. The reported effects resemble that of Escherichia coli heat-stable enterotoxin (ST). In this work the effects of ANP were studied in well established experimental systems and compared with that of ST. Both peptides induced a prompt secretion of water, Na, and Cl with no effects on K net transport in the in vivo rat perfused jejunum. The addition of ST, but not of ANP, evoked an increase of short circuit current in rat intestinal mucosa mounted in Ussing chambers. ST induced a significant increase in guanylate cyclase activity in intestinal homogenates, whereas ANP showed no effect. No binding sites for ANP were detected in basolateral or brush border membranes, nor in isolated enterocytes by a suction filtration technique. In conclusion, ANP acts as a short-lived intestinal secretagogue in the rat. Its mechanism of action is different from that of E. coli ST and appears to be indirect, since is not mediated by specific intestinal receptors and is not evident in vitro.

Abstract
The Authors describe a case report of a girl of 7 years affected by visceral leishmaniasis (VL) complicated by herpes zoster (Hz). Hz infection is unusual in paediatric age, but it may complicate immunodeficiency states. VL causes, as well known, T cell immunity depression: Hz infection could be facilitated by this situation.

Abstract
We report a case of transient gluten hypersensitivity, demonstrated by jejunal histology at diagnosis, normalization after gluten-free diet, and acute clinical and histological relapse after a challenge with gluten powder at the age of 1 year, resembling that observed in cow's milk protein intolerance. Subsequent provocation tests did not show any alteration. Cases of supposed transient gluten hypersensitivity are rarely reported; our patient is characterized by the acute reaction to gluten challenge associated with a damaged histological picture and depressed levels of complement.

Abstract
Jaundiced babies undergoing phototherapy often develop diarrhoea. The cause of it is still uncertain. Increasing evidence supports a role of a secretory mechanism for the diarrhoea. We therefore studied the effects of bile from congenitally jaundiced rats undergoing phototherapy and of unconjugated bilirubin on rat small intestine in vivo and in vitro. Results suggest that: (1) the bile from homozygous Gunn rats under phototherapy has an anti-absorptive effect when tested in the perfused jejunum of normal Wistar rats; (2) unconjugated bilirubin has a dose dependent secretory effect on the intestinal transport of water and electrolytes, when tested in the same system. Alteration of cyclic AMP or cyclic GMP, known intracellular mediators of secretion, was not observed. We conclude that free bilirubin is an intestinal secretagogue acting by an as yet unknown mechanism, that may mediate the secretory type of diarrhoea in jaundiced neonates undergoing phototherapy.
