Abstract
Esophageal stenosis is a relatively uncommon condition in pediatrics and requires an accurate diagnostic approach. Here we report the case of a 9-month old female infant who presented intermittent vomiting, dysphagia and refusal of solid foods starting after weaning. She was treated for gastroesophageal reflux. At first, radiological investigation suggested achalasia, while esophagoscopy revelaed a severe congenital esophageal stenosis at the distal third of the esophagus. She underwent four endoscopic balloon dilatations that then allowed her to swallow solid food with intermittent mild dysphagia. After 17 months of esomeprazole treatment off therapy impedance-pH monitoring was normal. At 29 months of follow-up the child is asymptomatic and eats without problems.Infants with dysphagia and refusal of solid foods may have undiagnosed medical conditions that need treatment. Many disorders can cause esophageal luminal stricture; in the pediatric age the most common are peptic or congenital. Careful assessment with endoscopy is needed to diagnose these conditions early and referral to a pediatric gastroenterologic unit may be necessary.

Abstract
Active particles may happen to be confined in channels so narrow that they cannot overtake each other (single-file conditions). This interesting situation reveals nontrivial physical features as a consequence of the strong interparticle correlations developed in collective rearrangements. We consider a minimal two-dimensional model for active Brownian particles with the aim of studying the modifications introduced by activity with respect to the classical (passive) single-file picture. Depending on whether their motion is dominated by translational or rotational diffusion, we find that active Brownian particles in single file may arrange into clusters that are continuously merging and splitting (active clusters) or merely reproduce passive-motion paradigms, respectively. We show that activity conveys to self-propelled particles a strategic advantage for trespassing narrow channels against external biases (e.g., the gravitational field).

Abstract
OBJECTIVE To evaluate gonadal function and uterine volume in a cohort of female survivors treated by chemotherapy, radiotherapy, and/or stem cell transplantation (SCT) for childhood malignant and non-malignant diseases. DESIGN An observational study. SETTING S. Matteo Hospital, Pavia, Italy. POPULATION A cohort of 135 female survivors. METHODS A clinical, hormonal, and ultrasonographic evaluation. Thirty-three patients (24%) had non-malignant haematologic diseases (thalassaemia or sickle cell anaemia), 68 (50%) had leukaemia, 23 (17%) had lymphomas, and 11 (8%) had solid tumours. In total, 106 patients had received SCT, preceded by a conditioning regimen. MAIN OUTCOME MEASURES Anti-Müllerian hormone (AMH) and Inhibin-B, and uterine volume. RESULTS The median concentrations of AMH and Inhibin-B in the entire cohort were 0.12 ng/ml (interquartile range, IQR, 0.1-0.5 ng/ml) and 3.5 pg/ml (IQR 0.1-13.2 pg/ml), respectively. In a stepwise ordered logistic regression analysis, conventional chemotherapy for the treatment of malignancies, as opposed to total body irradiation (TBI), was the only oncologically significant predictor of increased AMH levels (OR 4.8, 95% CI 1.9-12, P < 0.001). Conditioning treatment before or after menarche did not influence AMH concentrations (P = 0.24). The best predictor of reduced uterine volume was TBI during the preparation for the allograft (OR 3.5, 95% CI 1.4-8.4, P = 0.006). Increasing age at treatment (OR 0.86, 95% CI 0.77-0.95, P = 0.04), chemotherapy, as opposed to other treatments (OR 0.09, 95% CI 0.03-0.28, P < 0.001), and solid tumours as opposed to either leukaemia/lymphomas or non-malignant diseases (OR 0.2, 95% CI 0.07-0.56, P = 0.002) were associated with larger uterine volumes. CONCLUSIONS Conditioning therapies for SCT, including TBI, had the worst effects on uterine volume and gonadal reserve. Increasing age at treatment and conventional chemotherapy were associated with less detrimental effects on uterine volume.

Abstract
AIM To investigate the effects of uncomplicated vaginal delivery and epidural analgesia on fetal acid-base parameters in women with gestational diabetes (GDM) compared with controls. METHODS A retrospective case-control study of 142 women with gestational diabetes and 284 controls. To evaluate the effect of diabetes and analgesia on acid-base status correcting for potential confounders we used ordered logistic equations including quartiles of fetal arterial acid-base parameters collected at birth as outcomes and categories of diabetes and epidural analgesia as explanatory variables. RESULTS In the GDM group cord base deficit (-2.63 mmol/l, interquartile range [IQR]=4.2 to -0.65 mmol/l vs. -1.9 mmol/l, IQR=-3.3 to -0.2 mmol/l, p=0.009, odds ratio (OR)=1.51, 95% confidence interval (CI)=1.04-2.18) was lower and concentration of calcium higher (1.49 mmol/l, IQR=1.42-1.56 mmol/l vs. 1.47 mmol/l, IQR=1.41-1.51 mmol/l, p=0.009, OR=1.69, 95% CI=1.12-2.56) compared with controls. Epidural analgesia in the GDM group was associated with reduced cord concentration of glucose (84.0mg/dl [4.7 mmol/l], IQR=70-103.3mg/dl vs. 92.5mg/dl [5.1 mmol/l], IQR=76.5-121.8 mg/dl, p=0.004), lactate (2.65 mmol/l (IQR=1.80-4.20) vs. 3.70 mmol/l (IQR=2.90-5.55 mmol/l), p=0.002) and less pronounced base deficit (-2.05 mmol/l, IQR=-3.90 to -0.17 mmol/l vs. -2.8, IQR=-5.57 to -1.05 mmol/l, p=0.01, OR=0.7, 95% CI=0.49-0.99). CONCLUSIONS In uncomplicated pregnancies and deliveries, well-controlled gestational diabetes mellitus has potentially significant detrimental effects on fetal acid-base status at birth. Epidural analgesia reduces cord arterial glucose and lactates.

Abstract
Metal oxide nanoparticles, hybridized with various polymeric chemicals, represent a novel and breakthrough application in drug delivery, hyperthermia treatment and imaging techniques. Radiolabeling of these nanoformulations can result in new and attractive dual-imaging agents as well as provide accurate in vivo information on their biodistribution profile. In this paper a comparison study has been made between two of the most promising hybrid core-shell nanosystems, bearing either magnetite (Fe3O4) or cobalt ferrite (CoFe2O4) cores, regarding their magnetic, radiolabeling, hyperthermic and biodistribution properties. While hyperthermic properties were found to be affected by the metal-core type, the radiolabeling ability and the in vivo fate of the nanoformulations seem to depend critically on the size and the shell composition.

Abstract
We report the results of comprehensive experiments and numerical calculations of interfacial morphologies of water confined to the hydrophilic top face of rectangular posts of width W = 500 μm and lengths between L = 5W and 30W. A continuous evolution of the interfacial shape from a homogeneous liquid filament to a bulged filament and back is observed during changes in the liquid volume. Above a certain threshold length of L* = 16.0W, the transition between the two morphologies is discontinuous and a bistability of interfacial shapes is observed in a certain interval of the reduced liquid volume V/W(3).

Abstract
The state of sleep/wakefulness is well known to influence esophageal acid exposure and the number of acid refluxes whereas it is uncertain whether the same is true of the non-acid refluxes that predominate in the newborns. To investigate the relationship between sleep/wakefulness and refluxes 45 newborns with gastroesophageal reflux symptoms were studied with combined multichannel intraluminal impedance and pH monitoring. We found that sleep/wakefulness influenced acid and weakly acidic reflux frequency (awake 2.6+/-0.8; asleep 2.1+/-1.1; p=0.006). A negative correlation was found between sleepness periods and the mean reflux duration for both acid (R=0.55;p < 0.001) and weackly acidic (R=0.51;p < 0.001) refluxes. This finding may raise some concerns about the over-prescription of antacid drugs in newborns.

Abstract
AIM To evaluate modifications of gut microbiota after antibiotic therapy in breast-fed infants. STUDY DESIGN Twenty-six exclusively breast-fed infants younger than 5 months hospitalized for pneumonia treated with ceftriaxone (50 mg per kilo per day administered intramuscularly) were recruited. Intestinal microbiota at day 0 - before starting antibiotic administration - at the end of the therapy (5 days after) and after 15 days after the stop was analysed. Stool samples were collected and immediately diluted and cultured on selective media to detect total bacteria, Enterobacteriaceae, enterococci and lactobacilli. Statistical analysis was performed by using Wilcoxon test. RESULTS After 5 days of antibiotic therapy, we observed a significant reduction in total faecal bacterial count (p = 0.003) in Enterobacteriaceae (p = 0.001) and enterococci (p < 0.001), in comparison with day 0. After 5 days of therapy, lactobacilli are no longer detected. Conversely, bacterial count values for all bacteria detected after 15 days from the end of therapy are significantly increased and similar to day 0. CONCLUSION Our findings showed that gut microbiota was significantly modified after 5 days of antibiotic therapy; exclusively, breast-feeding may be relevant in promoting the re-establishment of gut microbiota composition in early infancy.

Abstract
e22174 Background: Uncommon breast tumors are often neglected by large clinical trials, even if their incidence is not so low. Methods: We investigated stage, treatment and outcome of 112 patients affected by uncommon breast cancer, out of 2,185 breast cancer patients diagnosed and followed in our Institution from January 1985 to October 2008. Results: Rare subtypes were represented as follows: tubular 2.7% (58 pts), mucinous 1.1% (25 pts), medullary 1% (21 pts), papillary 0.4% (8 pts). Median age at diagnosis was 56.5 years among patients with tubular histotype, 68.9 years for mucinous, 55 and 61.7 years for medullary and papillary, respectively. Stage I tumors were 87.7% among patients with tubular differentiation, 60% for mucinous, 26.3% for medullary and 50% for papillary, (compared to 45.7% in invasive ductal carcinoma: 1,626 pts). Stage II represented 12.3% among patients with tubular carcinoma, 32% for mucinous, 57.9% for medullary and 37.5% for papillary. Surgical option for stage I and stage II was usually conservative surgery (quadrantectomy, lumpectomy) plus local radiotherapy, followed by estrogenic blockade. In stage III radical mastectomy was often performed, followed by hormonal suppression. Median DFS for patients with tubular cancer was 4.1 years, for mucinous 3.7 years, 10.5 and 5.1 years for medullary and papillary, respectively. Median OS for patients with tubular cancer was 4.3 years, whereas for mucinous 4.2 years, for medullary 11 years and 5.3 years for papillary. Conclusions: In our retrospective analysis, uncommon breast tumors are often diagnosed at limited stages, resulting in good prognosis, with standard treatment. Further studies are warranted for a better management of these diseases. No significant financial relationships to disclose.

Abstract
AIM Phytotherapic agents, such as herbal formulations containing Matricariae recutita flowers (chamomile) extract, Foeniculum vulgare fruit (fennel) extract and Melissa officinalis aerial parts (lemon balm) extract have beneficial effects on gastrointestinal tract in colicky infants. However, the mechanism is largely unexplored and, particularly, it is not clear if it affects intestinal motility. The aim of this experimental study was to evaluate the effect of different herbal formulations containing Matricariae recutita extract, Foeniculum vulgare extract and Melissa officinalis extract on upper gastrointestinal transit in mice in vivo. METHODS Gastrointestinal transit was measured in male ICR mice and in croton oil-treated mice after the oral administration of herbal formulations containing chamomile, fennel and lemon balm (ColiMil) and chamomile and lemon balm (ColiMil experimental). RESULTS The herbal formulations tested (0.4-0.8 mL/mouse) dose-dependently and significantly inhibited gastrointestinal transit both in control and in croton oil-treated mice. Chamomile extract and lemon balm extract reduced significantly intestinal motility, but not fennel. At similar concentration ColiMil evoked a more consistent response than ColiMil experimental. CONCLUSION Our findings directly demonstrate in vivo the effect of a combination of herbal formulations on intestinal motility. The observed inhibitory effect might be studied with clinical studies to test the efficacy of these compounds in the treatment of colicky infants.

Abstract
We describe a case of adult polyglucosan body disease with characteristic clinical symptoms of peripheral neuropathy, upper motor neuron signs, and bowel and bladder dysfunction. Sural nerve biopsy revealed diagnostic intra-axonal polyglucosan bodies. On electron microscopic examination, the inclusions were located mainly within myelinated nerve fibers and consisted of branched filaments that were 6 to 8 nm wide. The diagnosis of adult polyglucosan body disease was confirmed by a skin biopsy from the axilla showing similar inclusions in myoepithelial cells of apocrine glands. This report provides additional evidence that skin biopsy, to date advocated by a single case report only, may be a less invasive and simpler diagnostic alternative to sural nerve or brain biopsies.

Abstract
BACKGROUND & AIMS The association of liver disease with hepatitis C virus (HCV) genotypes mainly refers to patients with serious liver damage; little information is available on symptomless carriers. The aim of this study was to investigate the correlation of genotypes with clinical course, risk factors for infection, and antibody to HCV reactivity in asymptomatic subjects. METHODS One hundred nine viremic blood donors with at least 1 year of follow-up were studied; 41 underwent liver biopsy. Genotypes were determined by line-probe assay. RESULTS Genotype 1 was found in 47 (43.1%), genotype 2 in 48 (44%), genotype 3 in 8 (7.3%), genotype 4 in 2 (1.8%), and coinfections in 4 (3.7%). The relative risk (RR) for a raised pattern of alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyltranspeptidase was 2.1 (confidence interval [CI], 1.4-3.2), 1.7 (CI, 1.2-2.4), and 2.8 (CI, 1.6-4.9) in subjects with genotype 1 vs. 0.4 (CI, 0.2-0.7), 0.4 (CI, 0.3-0.7), and 0.4 (CI, 0.2-0.8) in subjects with genotype 2. Chronic hepatitis was found in 68%; the RR of chronic hepatitis was similar for genotypes 1 and 2 (RR, 1.1 [CI, 0.8-1.7] vs. RR, 1.0 [CI, 0.7-1.6]). Reactivity to NS4-derived antigens was infrequent in type 2-infected subjects. CONCLUSIONS Genotype 2 was as frequent as genotype 1 but associated with less liver function impairment. The high prevalence of chronic hepatitis should be considered in counseling viremic asymptomatic donors.

Abstract
Serum levels of total sialic acid, carcinoembryonic antigen (CEA), ferritin, lactate dehydrogenase, and creatine phosphokinase were measured both in tumor drainage blood (axillary vein) and in peripheral blood obtained from 121 breast cancer patients during surgery. No significant differences between mean values in peripheral and tumor draining blood, between cancer patients and healthy controls, or between patients with or without axillary lymph node metastases were found for any of the markers. Both ferritin and CEA levels were higher in axillary and peripheral blood from patients with central breast cancer versus other sites but the difference was significant only for CEA (p less than 0.05). CEA levels were significantly higher (p less than 0.01) in patients with greater than 2 cm diameter carcinomas versus T1 stage patients in axillary but not in peripheral blood. When the cephalic vein was clamped before the axillary sample was taken, ferritin showed a significant increase (p less than 0.05). We conclude that measurement of sialic acid, CEA, and ferritin in axillary venous blood in breast cancer patients is not of clinical benefit, although further data are needed to clarify whether other advantages can be derived.

Abstract
To investigate the psychologic adjustment of women undergoing radical mastectomy for cancer, we compared drug consumption (analgesics and sedatives) in the postoperative period and the time lag between operation and the first spontaneous observation of surgical wound in two groups operated according to different procedures. Group 1 (52 patients; mean age, 47 years) underwent a two-stage surgical treatment consisting of biopsy (local anesthesia) followed after 2-4 h by mastectomy (general anesthesia); in the interval patients were informed about ongoing procedures by the surgeon, who also pronounced some key words such as tumor, malignant disease, cancer. Group 2 (66 patients; mean age, 47 years) underwent biopsy and mastectomy in a single stage under general anesthesia. The relative risk (RR) of Group 1 vs Group 2 patients was calculated as regards both drug consumption and time of the first self-observation of the surgical wound. Our results seem to suggest that the two-stage procedure through special care given by the surgeon may result in a positive coping pattern and thus better acceptance of the mutilation.

Abstract
Eleven international jumpers and throwers engaged in year round training were divided into experimental (n = 6) and control (n = 5) groups. The experimental group was tested before and after a 3 weeks simulated hypergravity period, and again 4 weeks after the hypergravity period. The high gravity condition was created by wearing a vest weighing about 13% of the subjects body weight. The vest was worn from morning to evening including the training sessions, and only removed during sleep. The daily training of all subjects consisted of classical weight training and jumping drills. No changes in the ordinary training program were allowed in the experimental group, except for the use of the vest. Vertical jumps, drop jumps and a 15 s continuous jumping test were used to measure the explosive power characteristics of the subjects. After the hypergravity period the experimental subjects demonstrated significant (5-10%, P less than 0.05-0.01) improvements in most of the variables studied: however, 4 weeks after cessation of the high gravity period they tended to return towards the starting values. No changes were observed in the results of the control group. The improvement observed in the experimental subjects was explained as fast adaptation to the simulated high gravity field. It is suggested that adaptation had occurred both in neuromuscular functions and in metabolic processes.

Abstract
Perchloric acid soluble proteins (PPS) and their content of N-acetylneuraminic acid (NANA) may serve as valuable tumor markers for a variety of malignant neoplasms. To evaluate their clinical significance, PPS, NANA and carcino-embryonic antigen (CEA) were measured in 32 patients with lung cancer. High PPS (greater than or equal to 0,73 mg/ml) and NANA (greater than or equal to 96 micrograms/ml) levels occurred in 8 of 50 (16%) healthy volunteers and respectively in 22% and 54% of patients. CEA levels were high (greater than or equal to 3 ng/ml) in 1 out of 21 (5%) healthy volunteers and in 83% of the patients; 84% of the patients showed an elevation of NANA and of CEA. The highest values of the three markers seem to be associated with extensive disease but no statistically significant difference has emerged from the comparison of patients with limited disease with the ones with extensive involvement. Changes of the tumor mass correlate with changes of serum levels of PPS, NANA and CEA. It is concluded that CEA determination is clinically valuable in lung cancer, while PPS and NANA do not provide greater information.

Abstract
The effect of ketoprofen (Orudis, Farmitalia) on ADP, epinephrine (EPI) and collagen (COLL) induced platelet aggregation (PlA), simplate bleeding time (SBT), partial thromboplastin time (PTT) and per cent prothrombin activity (PrA) was studied in eleven patients, four males and seven females (median age 59 years) with rheumatoid arthritis (six cases), cancer (four cases) and osteoarthrosis (one case). Tests were performed before and 1, 8 and 24 hours after a single intravenous dose (600 mg) of ketoprofen and on Days 4 and 8 during a 7-day treatment (200 mg i.v. every 8 hours) and 1 day after withdrawal of the drug. PTT and PrA were not affected by the drug. Bleeding time was not significantly modified by the acute treatment, but was prolonged during the subacute course, though it was not different from baseline values at the end of the trial. Significant reduction of platelet aggregation was seen in both acute and subacute conditions with complete or almost complete recovery 36 hours after the last dose. It is concluded that ketoprofen affects platelets with readily reversible inhibition of in vitro aggregation and a slight increase of bleeding time.
