Case report: Gastroenterological management in a case of cardio-facio-cutaneous syndrome.

Background: cardio-facio-cutaneous syndrome is a rare genetic disorder affecting less than 900 people in the world. It is mainly characterized by craniofacial, dermatologic and cardiac defects, but also gastroenterological symptoms may be present, ranging from feeding difficulties to gastroesophageal reflux and constipation.In this report we describe a case of this syndrome characterized by severe feeding and growth difficulties, with a particular focus on the management of gastroenterological complications. Case presentation: the patient was a caucasian male affected by Cardio-Facio-Cutaneous syndrome who presented feeding difficulties already a few hours after birth. These symptoms worsened in the following months and lead to a complete growth arrest and malnutrition. He was first treated with a nasogastric tube placement. Subsequently, a laparoscopic Nissen fundoplication and a laparoscopic Stamm gastrostomy were performed. The child was fed with nocturnal enteral nutrition and diurnal oral and enteral nutrition. Eventually the patient resumed feeding validly and regained adequate growth. Conclusion: this paper aims to bring to light a complex rare syndrome that infrequently comes to the attention of the pediatricians and whose diagnosis is not always straightforward. We also highlight the possible complications under a gastroenterologic point of view. Our contribution can be helpful to the pediatrician in the first diagnostic suspect of this syndrome. In particular, it is worth highlighting that -in an infant with Noonan-like features- symptoms like suction or swallowing problems, vomiting and feeding difficulties should orient towards the diagnosis of a Cardio-facio-cutaneous syndrome. It is also important to stress that its related gastroenterological issues may lead to severe growth failure and therefore the role of the gastroenterologist is key to manage supplemental feeding and to establish whether a nasogastric or gastrostomic tube placement is necessary.

Systemic corticosteroids could be used as bridge treatment in children with obstructive sleep apnea syndrome waiting for surgery.

PURPOSE: Local and systemic inflammatory markers and pro-inflammatory cytokines are increased in children with obstructive sleep apnea syndrome (OSAS). Therefore, systemic or topical anti-inflammatory agents are used to treat this syndrome. We evaluated the treatment with systemic corticosteroids in children with severe OSAS and adenotonsillar hypertrophy before surgery. METHODS: This was an unblinded open label study. Children with severe OSAS (diagnosed through polysomnography, obstructive apnea-hypopnea index [AHI] > 10 eV/h) were recruited. Exclusion criteria included age < 3 years, history of acute or chronic cardiorespiratory or neuromuscular or metabolic disease; major craniofacial abnormalities; and chromosomal syndromes and epilepsy. Computer-generated random numbers were used for simple randomization of subjects. All children were treated with intranasal beclomethasone spray, and 15 children additionally received oral betamethasone and 0.1 mg/kg per day for 7 days. Sleep clinical record (SCR) and pulsoximetry were performed before and after 7 days in all children. RESULTS: Among 28 children with severe OSAS mean age was 4.5 ± 1.8 years, AHI 20.4 ± 1.8 eV/h). In children treated with intranasal and oral corticosteroids, mean (95.3 ± 1.1 vs 97.0 ± 0.8%, p = 0.0001) and minimum oxygen saturation (78.8 ± 6.3 vs 89.2 ± 4.2, p = 0.001) improved, and the SCR score (12.6 ± 1.2 vs 8.3 ± 1.1, p = 0.0001) was reduced. Children treated only with intranasal beclomethasone spray showed no differences in outcome measures before and after treatments. When we considered the oximetry measures, after corticosteroid treatment, we obtained statistical differences between the 2 groups (p < 0.01). CONCLUSIONS: These results seem to suggest that a short course of oral betamethasone could be useful to treat children with severe OSAS and adenotonsillar hypertrophy waiting for surgery.

Chronic intestinal pseudo-obstruction in children and adults: diagnosis and therapeutic options.

BACKGROUND: Chronic intestinal pseudo-obstruction (CIPO) represents the most severe form of gastrointestinal dysmotility with debilitating and potentially lethal consequences. Symptoms can be non-specific, and result in this condition being diagnosed incorrectly or too late with consequences for morbidity and even mortality. PURPOSE: The present article aims to provide pediatric and adult gastroenterologists with an up to date review about clinical features, diagnosis and therapeutic options for CIPO. Although pediatric and adult CIPO share many clinical aspects distinctive features can be identified. There is no single diagnostic test or pathognomonic finding of CIPO, thus a stepwise approach including radiology, endoscopy, laboratory, manometry, and histopathology should be considered in the diagnostic work-up. Treatment of patients with CIPO is challenging and requires a multidisciplinary effort with participation of appropriately experienced gastroenterologists, pathologists, dieticians, surgeons, psychologists, and other subspecialists based on the presence of comorbidities. Current treatment options invariably involve surgery and specialized nutritional support, especially in children. Medical therapies are mainly aimed to avoid complications such as sepsis or intestinal bacterial overgrowth and, where possible, restore intestinal propulsion. More efficacious therapeutic options are eagerly awaited for such difficult patients.

Use of macrogol 4000 in chronic constipation.

BACKGROUND: Chronic constipation is a common functional disorder of the gastrointestinal tract, affecting up to 35% of the general population, and especially the elderly. However, its definition as perceived by the patient can vary, making it difficult to understand the problem and find appropriate therapeutic measures. The approach to chronic constipation, thus, needs a thorough understanding of the patient's complaint and the main pathophysiological mechanism requiring treatment. Lifestyle changes do not usually meet with complete patient satisfaction. Other treatments include different types of laxatives. Of these, osmotic laxatives appear one of the most effective and are, therefore, frequently prescribed. DESIGN: This review will cover the topic of osmotic laxatives, specifically focusing on polyethylene glycol (PEG/macrogol 4000) in chronic constipation and as a key agent for bowel cleansing prior to colonoscopy. PEG formulations, including macrogol 4000, are safe, effective treatments for constipation, even in children and elderly patients. Macrogol 4000 may well be more palatable than combined formulations (macrogol 3350 with electrolytes), which could help improve adherence to the long-term treatment required for chronic constipation. CONCLUSIONS: PEG/macrogol is also recommended as an effective option for bowel cleansing prior to colonoscopy. The improved cost-effectiveness of macrogol over other commonly prescribed laxatives, such as lactulose, should be taken into consideration.

Methotrexate in paediatric ulcerative colitis: a retrospective survey at a single tertiary referral centre.

BACKGROUND: Patients with ulcerative colitis often receive thiopurines as immunomodulators (IMs) to maintain remission and avoid corticosteroids. If unresponsive or intolerant to these agents, patients are treated with methotrexate, an antimetabolite never assessed in paediatric ulcerative colitis. AIM: To describe the experience with methotrexate in children with ulcerative colitis. METHODS: Thirty-two patients (median age 13.9 years) received methotrexate. Pediatric Ulcerative Colitis Activity Index (PUCAI) and use of corticosteroids were the main outcomes evaluated at baseline and at 3, 6 and 12 months. RESULTS: Indications to methotrexate were azathioprine unresponsiveness in 18 patients, azathioprine intolerance/toxicity in 10 and spondyloarthropathy in four. Response or remission was achieved in 72%, 63% and 50% of patients at 3, 6 and 12 months respectively. Mean PUCAI were 49.5 ± 23.3 at baseline and 32.9 ± 21.9, 29.5 ± 21.8 and 29.4 ± 19.9 at 3, 6 and 12 months respectively (P: 0.03). At the beginning of methotrexate, 16 patients (50%) received corticosteroids that were discontinued in 13 of them (81%) by 6 months. At the end of the study, 11 patients (33%) needed short courses of corticosteroids for disease relapse. CONCLUSIONS: Methotrexate may be useful in treating children with ulcerative colitis, although large, controlled trials are warranted to define better its effectiveness.

JC Viral reactivation in a pediatric patient with Crohn's disease.

This is a report concerning human polyomavirus JC (JCV) reactivation in a pediatric patient with Crohn's disease (CD) during the treatment with 5-aminosalicylic acid (5-ASA), a non-steroidal anti-inflammatory drug (NSAID). We examined 9 bioptic samples from three different bowel districts (ileum, cecum, rectum) of this child. These samples were analyzed by Quantitative PCR (Q-PCR) to investigate the presence of JCV DNA. JCV DNA was detected in one rectum biopsy taken two months after 5-ASA treatment. Although our result must be validated in a larger group of subjects and with a longer follow-up period, it underlines the importance of JVC monitoring in CD patients.

New therapeutic approach in the management of intestinal disease: probiotics in intestinal disease in paediatric age.

Current evidence supports the view that oral administration of probiotics may be of therapeutic usefulness in several clinical disorders by reestablishing normal flora in the gastrointestinal tract. These entities include inflammatory and infectious diseases of the gut as well as extraintestinal disorders (such as atopic eczema) in which a defective intestinal permeability plays a role. The probiotic effects are attributed to restoration to normal of increased intestinal permeability, unbalanced gut microecology, improved immunological gut barrier function, downregulation of the intestinal inflammatory responses with reduced generation of proinflammatory cytokines. Entities for which the impact of probiotic administration can be considered as proven are Rotavirus diarrhoea, Clostridium difficile diarrhoea, post-antibiotic diarrhoea, allergic diseases. On the other hand, entities for which administration of probiotics is considered under investigation are inflammatory bowel disease, necrotizing enterocolitis, cystic fibrosis, small bowel bacterial contamination, functional gastrointestinal disorders. The value of probiotics as therapy for a variety of gastrointestinal disorders in childhood still needs to be investigated in detail, through well controlled and rigorous studies, including a placebo group and strict criteria of randomisation. Much work needs to be done in this area by clearly defining indications, delivery system, costs, safety long-term effects.

Role of drug therapy in the treatment of gastro-oesophageal reflux disorder in children.

Gastro-oesophageal reflux (GOR) is the effortless passage of gastric contents into the distal oesophagus. It can be classified as functional (or symptomatic), in which the infant remains free from disease, or a pathological (GOR disease, GORD), in which gastrointestinal, respiratory or neurobehavioural signs occur with intraoesophageal acidification and the development of oesophagitis. Functional or symptomatic GOR is successfully treated by conservative measures and does not require investigative diagnostic tools; however, both drug administration and an investigative approach are mandatory in patients with GORD. There is currently a great range of proven therapeutic options for GORD that are directed at counteracting the pathogenetic components of the disorder. In this report we discuss the role of different drug classes for treating GORD in children. The choice of therapy for GORD depends upon the severity of signs and the degree of oesophagitis. The presence of oesophagitis, as documented by endoscopy, suggests the use of antisecretory drugs; H2 receptor antagonists are the first-line agents. Nevertheless, individuals with refractory disease or those patients requiring potent inhibition of acid secretion (for example, GORD with respiratory involvement) can be given proton pump inhibitors. Other groups of patients who need potent inhibition of acid secretion are children with neurological dysfunction and those with Barrett's oesophagus. It is still unclear whether patients with frequent relapses are candidates for long term administration of antisecretory drugs or for surgical fundoplication.

[Pretreatment evaluation of CA 72.4 in patients with carcinoma of the stomach (0-IV stage) versus CEA, TPA, CA 19-9, FER]. / Valutazione pretrattamento del CA 72.4 in pazienti con carcinoma gastrico (stadio 0-IV) vs CEA, TPA, CA 19-9 FER.

Before surgical treatments, sera of 54 pts suffering from gastric cancer, histologically typed and clinically staged (from stage 0 to 4), were assayed to evaluate CEA, TPA, CA 19-9 and Ferritin versus a new tumoral marker called TAG-72, in order to determine the biological behaviour and the relation to the clinical stage of this last one. Starting from their results, Authors say that the new marker TAG 72 has an increasing sensibility according to the clinical stage (4 th more than 1 st), and that the association of the TAG-72 plus CEA and/or TPA is rather significant in order to evaluate the evolution of the gastric cancer than other markers.
