Abstract
PURPOSE Serum calcium/phosphate ratio (Ca/P) has been recently proposed as an additional tool to identify primary hyperparathyroidism (PHPT), especially in patients with subclinical presentation, with a proposed cut-off of 3.3 when both values are expressed in mg/dL. No data are available on the relationship between Ca/P and the clinical presentation of PHPT. We thus evaluated this relationship in a large, single-center, unselected series. METHODS 515 consecutive PHPT patients (mean age 65 ± 13.15 years, 77.1% females) were retrospectively evaluated at diagnosis. RESULTS Mean Ca/P was 4.54 ± 1.5 (range 2.36-13.9), being higher than 3.3 in 88.5% of patients. Ca/P was significantly higher in (1) males, (2) symptomatic PHPT, (3) patients with 25-hydroxy vitamin D levels lower than 20 μg/L, (4) patients with osteitis fibrosa cystica, (5) patients with T score < - 2.5 at the radial site. In a multivariate regression analysis, Ca/P resulted significantly associated with PTH levels. After the exclusion of 57 patients with asymptomatic PHPT (aPHPT) patients and serum Ca higher than 1 mg/dL above the upper limit of normal range, no differences were found in Ca/P between aPHPT meeting or not surgical criteria. CONCLUSIONS In PHPT Ca/P ratio is associated with increased biochemical and clinical severity of disease and represents a direct indicator of clinical bone damage. However, it does not seem an additional tool to identify aPHPT patients reaching surgical indication.

Abstract
PURPOSE Evaluation of the phenotype of primary hyperparathyroidism (PHPT), adherence to International Guidelines for parathyroidectomy (PTx), and rate of surgical cure. METHOD From January 2014-January 2016, we performed a prospective, multicenter study in patients with newly diagnosed PHPT. Biochemical and instrumental data were collected at baseline and during 1-year follow-up. RESULTS Over the first year we enrolled 604 patients (age 61 ± 14 years), mostly women (83%), referred for further evaluation and treatment advice. Five hundred sixty-six patients had sporadic PHPT (93.7%, age 63 ± 13 years), the remaining 38 (6.3%, age 41 ± 17 years) had familial PHPT. The majority of patients (59%) were asymptomatic. Surgery was advised in 281 (46.5%). Follow-up data were available in 345 patients. Eighty-seven of 158 (55.1%) symptomatic patients underwent PTx. Sixty-five (53.7%) of 121 asymptomatic patients with at least one criterion for surgery underwent PTx and 56 (46.3%) were followed without surgery. Negative parathyroid imaging studies predicted a conservative approach [symptomatic PHPT: OR 18.0 (95% CI 4.2-81.0) P < 0.001; asymptomatic PHPT: OR 10.8, (95% CI 3.1-37.15) P < 0.001). PTx was also performed in 16 of 66 (25.7%) asymptomatic patients without surgical criteria. Young age, serum calcium concentration, 24 h urinary calcium, positive parathyroid imaging (either ultrasound or MIBI scan positive in 75% vs. 16.7%, P = 0.001) were predictors of parathyroid surgery. Almost all (94%) of patients were cured by PTx. CONCLUSIONS Italian endocrinologists do not follow guidelines for the management of PHPT. Negative parathyroid imaging studies are strong predictors of a non-surgical approach. PTx is successful in almost all patients.

Abstract
Suppression of detachment-induced cell death, known as anoikis, is an essential step for cancer metastasis to occur. We report here that expression of KLF12, a member of the Kruppel-like family of transcription factors, is downregulated in lung cancer cell lines that have been selected to grow in the absence of cell adhesion. Knockdown of KLF12 in parental cells results in decreased apoptosis following cell detachment from matrix. KLF12 regulates anoikis by promoting the cell cycle transition through S phase and therefore cell proliferation. Reduced expression levels of KLF12 results in increased ability of lung cancer cells to form tumours in vivo and is associated with poorer survival in lung cancer patients. We therefore identify KLF12 as a novel metastasis-suppressor gene whose loss of function is associated with anoikis resistance through control of the cell cycle.

Abstract
BACKGROUND Mild primary hyperparathyroidism (PHPT) was recently clearly defined for the first time. Our study was thus aimed to pinpoint proportion and clinical characteristics of this kind of patients. DESIGN AND PATIENTS We retrospectively evaluated our series of 360 consecutive patients with PHPT, selecting those with all features allowing a correct classification (serum total and ionized calcium, phosphate, creatinine, PTH, 25OHD, urinary calcium, renal and neck ultrasound, MIBI scintiscan, and DEXA at lumbar spine, femoral neck, and distal third of radius). Patients were defined asymptomatic (aPHPT) when bone or kidney was not involved and no hypercalcemic symptom occurred; mild PHPT was defined as aPHPT not meeting updated surgical criteria. RESULTS Seventy-five patients among 172 classified as aPHPT had all available data required for surgical evaluation and could be evaluated. Sixty/75 met surgical criteria and the remaining 15 were classified as mild. Mild PHPT patients had lower total and ionized calcium, urinary calcium, and PTH levels than aPHPT meeting surgical criteria, while vitamin D levels and BMD were similar. CONCLUSIONS Mild PHPT strictly defined according to the last consensus represents a small subgroup with a less active form of the disease.

Abstract
BACKGROUND Transpeople often look for sex reassignment surgery (SRS) to improve their quality of life (QoL). The hormonal therapy has many positive effects before and after SRS. There are no studies about correlation between hormonal status and QoL after SRS. AIM To gather information on QoL, quality of sexual life and body image in transpeople at least 2 years after SRS,to compare these results with a control group and to evaluate the relations between the chosen items and hormonal status. SUBJECTS AND METHODS Data from 60 transsexuals and from 60 healthy matched controls were collected. Testosterone,estradiol, LH and World Health Organization Quality of Life (WHOQOL-100) self-reported questionnaire were evaluated. Student’s t test was applied to compare transsexuals and controls. Multiple regression model was applied to evaluate WHOQOL’s chosen items and LH. RESULTS The QoL and the quality of body image scores intranspeople were not statistically different from the matched control groups’ ones. In the sexual life subscale,transwomen’s scores were similar to biological women’s ones, whereas transmen’s scores were statistically lower than biological men’s ones (P = 0.003). The quality of sexual life scored statistically lower in transmen than intranswomen (P = 0.048). A significant inverse relationship between LH and body image and between LH and quality of sexual life was found. CONCLUSIONS This study highlights general satisfaction after SRS. In particular, transpeople’s QoL turns out to be similar to Italian matched controls. LH resulted inversely correlated to body image and sexual life scores.

Abstract
We report the association of primary hyperparathyroidism (PHPT) and Klinefelter's syndrome (KS) in a 22-year-old male complaining of worsening fatigue. PHPT was asymptomatic at the diagnosis, but the patient had worsening hypercalcemia and osteoporosis, and developed acute renal colic. He then underwent parathyroidectomy with resection of a single adenoma and normalization of calcium and parathyroid hormone levels. Clinical and therapeutic implications of this rare association are discussed.

Abstract
BACKGROUND The relationship between the risk of celiac disease and both the age at which gluten is introduced to a child's diet and a child's early dietary pattern is unclear. METHODS We randomly assigned 832 newborns who had a first-degree relative with celiac disease to the introduction of dietary gluten at 6 months (group A) or 12 months (group B). The HLA genotype was determined at 15 months of age, and serologic screening for celiac disease was evaluated at 15, 24, and 36 months and at 5, 8, and 10 years. Patients with positive serologic findings underwent intestinal biopsies. The primary outcome was the prevalence of celiac disease autoimmunity and of overt celiac disease among the children at 5 years of age. RESULTS Of the 707 participants who remained in the trial at 36 months, 553 had a standard-risk or high-risk HLA genotype and completed the study. At 2 years of age, significantly higher proportions of children in group A than in group B had celiac disease autoimmunity (16% vs. 7%, P=0.002) and overt celiac disease (12% vs. 5%, P=0.01). At 5 years of age, the between-group differences were no longer significant for autoimmunity (21% in group A and 20% in group B, P=0.59) or overt disease (16% and 16%, P=0.78 by the log-rank test). At 10 years, the risk of celiac disease autoimmunity was far higher among children with high-risk HLA than among those with standard-risk HLA (38% vs. 19%, P=0.001), as was the risk of overt celiac disease (26% vs. 16%, P=0.05). Other variables, including breast-feeding, were not associated with the development of celiac disease. CONCLUSIONS Neither the delayed introduction of gluten nor breast-feeding modified the risk of celiac disease among at-risk infants, although the later introduction of gluten was associated with a delayed onset of disease. A high-risk HLA genotype was an important predictor of disease. (Funded by the Fondazione Celiachia of the Italian Society for Celiac Disease; CELIPREV ClinicalTrials.gov number, NCT00639444.).

Abstract
OBJECTIVE Perfusion CT may have the potential to quantify the degree of angiogenesis of solid tumours in vivo. This study aims to identify the practical and technical challenges inherent to the technique, and evaluate its feasibility in colorectal tumours. METHODS 51 patients from 2 institutions prospectively underwent a single perfusion CT on 2 different multidetector scanners. The patients were advised to breath-hold as long as possible, followed by shallow breathing, and were given intravenous buscopan to reduce movement. Numerous steps were explored to identify the challenges. RESULTS 43 patients successfully completed the perfusion CT as per protocol. Inability to detect the tumour (n=3), misplacement of dynamic sequence co-ordinates (n=2), failure of contrast injection (n=2) and displacement of tumour (n=1) were the reasons for failure. In 14 cases excessive respiratory motion displaced the tumour out of the scanning field along the temporal sequence, leading to erroneous data capture. In nine patients, minor displacements of the tumour were corrected by repositioning the region of interest (ROI) to its original position after reviewing each dynamic sequence slice. In 20 patients the tumour was stable, and data captured from the ROI were representative, and could have been analysed by commercially available Body Tumor Perfusion 3.0® software (GE Healthcare, Waukesha, WI). Hence all data were manually analysed by MATLAB® processing software (MathWorks, Cambridge, UK). CONCLUSION Perfusion CT in tumours susceptible to motion during acquisition makes accurate data capture challenging and requires meticulous attention to detail. Motion correction software is essential if perfusion CT is to be used routinely in colorectal cancer.

Abstract
The (Z)-4,4,4-trifluoro-3-(2-hydroxyethylamino)-1-(2-hydroxyphenyl)-2-buten-1-one (C(12)H(12)F(3)NO(3)) compound was thoroughly studied by IR, Raman, UV-visible, and (13)C and (19)F NMR spectroscopies. The solid-state molecular structure was determined by X-ray diffraction methods. It crystallizes in the P2(1)/c space group with a = 12.1420(4) Å, b = 7.8210(3) Å, c = 13.8970(5) Å, β = 116.162(2)°, and Z = 4 molecules per unit cell. The molecule shows a nearly planar molecular skeleton, favored by intramolecular OH···O and NH···O bonds, which are arranged in the lattice as an OH···O bonded polymer coiled around crystallographic 2-fold screw-axes. The three postulated tautomers were evaluated using quantum chemical calculations. The lowest energy tautomer (I) calculated with density functional theory methods agrees with the observed crystal structure. The structural and conformational properties are discussed considering the effect of the intra- and intermolecular hydrogen bond interactions.

Abstract
BACKGROUND AND AIMS Chronic intestinal failure is a condition causing severe impairment of intestinal functions; long-term total parenteral nutrition is required to provide adequate nutritional support. METHODS This is a 15-year follow-up study of paediatric patients with intestinal failure receiving long-term home parenteral nutrition. RESULTS Thirty-six patients were included in the study, all aged <16 years. Total parenteral nutrition and home parenteral nutrition were administered respectively to 100.97 and 85.20 patients-year. Today, 12 out of 36 patients are still on parenteral nutrition. A total of 99 central venous catheters were inserted, for mean 2.75 catheters/patient. The overall incidence rates of catheter-related complications was 1.79 per 1000 days-catheter for sepsis and 3.37 per 1000 days-catheter for mechanical complications. Two multivariate Cox-models have been used to examine the role of some predictors for septic or mechanical complications. The only risk factor for septic complications was the indication for parenteral nutrition, and the only predictor of mechanical complications was the insertion period. CONCLUSIONS Our experience in the treatment of paediatric patients with gastrointestinal diseases confirms that long-term parenteral nutrition has become a safe and appropriate method in the treatment of severe chronic intestinal failure.

Abstract
OBJECTIVE To evaluate the prevalence of beta-cell autoimmunity and the usefulness of a type 1 diabetes screening in patients with celiac disease. RESEARCH DESIGN AND METHODS We measured GAD antibodies (GADAs), insulinoma-associated protein 2 antigens (IA-2As), and insulin autoantibodies (IAAs) in 188 young Italian patients with celiac disease (66 male [35.1%]). Mean age at celiac disease diagnosis was 5.4 years (0.5-17.1), and mean celiac disease duration was 4.2 years (0-28.8). Celiac disease was diagnosed by jejunal biopsy after positivity for endomysial and tissue transglutaminase antibody was confirmed. RESULTS GADAs were positive in seven patients (3.7%), and IA-2As were positive in two patients. IAAs were negative in all cases. Metabolic evaluation was normal, and no patients developed diabetes during follow-up. There was no significant association among beta-cell autoimmunity and sex, age, pubertal stage, family history, or coexistence of other autoimmune disorders; compliance to a gluten-free diet was confirmed. CONCLUSIONS Our results showed a low prevalence of beta-cell autoimmunity and do not support a precocious screening for beta-cell autoimmunity in young celiac disease patients.

Abstract
A Flow Injection Analysis (FIA) spectrofluorimetric method for calcium determination in ice cores was optimised in order to achieve better analytical performances which would make it suitable for reliable calcium measurements at ppt level. The method here optimised is based on the formation of a fluorescent compound between Ca and Quin-2 in buffered environment. A careful evaluation of operative parameters (reagent concentration, buffer composition and concentration, pH), influence of interfering species possibly present in real samples and potential favourable effect of surfactant addition was carried out. The obtained detection limit is around 15 ppt, which is one order of magnitude lower than the most sensitive Flow Analysis method for Ca determination currently available in literature and reproducibility is better than 4% for Ca concentrations of 0.2 ppb. The method was validated through measurements performed in parallel with Ion Chromatography on 200 samples from an alpine ice core (Lys Glacier) revealing an excellent fit between the two chemical series. Calcium stratigraphy in Lys ice core was discussed in terms of seasonal pattern and occurrence of Saharan dust events.

Abstract
Bullous pemphigoid (BP) is an autoimmune skin disease that occurs mainly in elderly patients; onset of BP is rare in childhood. Inflammatory bowel diseases (IBD), by contrast, have a pediatric onset in 25% of presenting cases, requiring expert multidisciplinary management. Here we report a pediatric case of IBD (involving stomach, duodenum, ileum, and colon-rectum) associated with a disseminated form of drug-resistant BP successfully treated by plasma exchange (PEX), extracorporeal photochemotherapy (ECP), and corticosteroid therapy. The addition of PEX and ECP to standard treatment induced no severe side effects, prompted a rapidly achieved complete and long-term remission, and allowed dose tapering of the immunosuppressive drugs over an 18-month follow-up.

Abstract
We characterized differential gene expression profiles of fibroblast cell lines harboring single or double-homozygous null mutations in H-ras and N-ras. Whereas the expression level of the individual H-, N- and K-ras genes appeared unaffected by the presence or absence of the other ras loci, significant differences were observed between the expression profiles of cells missing N-ras and/or H-ras. Absence of N-ras produced much stronger effects than absence of H-ras over the profile of the cellular transcriptome. N-ras(-/-) and H-ras(-/-) fibroblasts displayed rather antagonistic expression profiles and the transcriptome of H-ras(-/-) cells was significantly closer to that of wild-type fibroblasts than to that of N-ras(-/-) cells. Classifying all differentially expressed genes into functional categories suggested specific roles for H-Ras and N-Ras. It was particularly striking in N-ras(-/-) cells the upregulation of a remarkable number of immunity-related genes, as well as of several loci involved in apoptosis. Reverse-phase protein array assays demonstrated in the same N-ras(-/-) cells the overexpression and nuclear migration of tyrosine phosphorylated signal transducer and activator of transcription 1 (Stat1) which was concomitant with transcriptional activation mediated by interferon-stimulated response elements. Significantly enhanced numbers of apoptotic cells were also detected in cultures of N-ras(-/-) cells. Our data support the notion that different Ras isoforms play functionally distinct cellular roles and indicate that N-Ras is significantly involved in immune modulation/host defense and apoptotic responses.

Abstract
Sea ice and dust flux increased greatly in the Southern Ocean during the last glacial period. Palaeorecords provide contradictory evidence about marine productivity in this region, but beyond one glacial cycle, data were sparse. Here we present continuous chemical proxy data spanning the last eight glacial cycles (740,000 years) from the Dome C Antarctic ice core. These data constrain winter sea-ice extent in the Indian Ocean, Southern Ocean biogenic productivity and Patagonian climatic conditions. We found that maximum sea-ice extent is closely tied to Antarctic temperature on multi-millennial timescales, but less so on shorter timescales. Biological dimethylsulphide emissions south of the polar front seem to have changed little with climate, suggesting that sulphur compounds were not active in climate regulation. We observe large glacial-interglacial contrasts in iron deposition, which we infer reflects strongly changing Patagonian conditions. During glacial terminations, changes in Patagonia apparently preceded sea-ice reduction, indicating that multiple mechanisms may be responsible for different phases of CO2 increase during glacial terminations. We observe no changes in internal climatic feedbacks that could have caused the change in amplitude of Antarctic temperature variations observed 440,000 years ago.

Abstract
During the 2002-2003 austral summer field season, aerosol samples were collected at a coastal (Terra Nova Bay--Northern Victoria Land) and an inland site (Dome C--East Antarctic Plateau). The sampling was carried out by stacked filter units made up of two filters at different porosity (5.0 and 0.4 microm at Terra Nova Bay and 3.0 and 0.4 microm at Dome C), able to roughly separate a coarse from a fine fraction. At Dome C, a further investigation on aerosol size distribution was performed by an inertial impactor able to collect aerosol particles on 8 size classes (from 10 to 0.4 microm). Atomic Force Microscopy was applied to the filter collecting the finer fraction in both sites in order to assess the real cut-off value of the filter sandwich apparatus and to reconstruct the volume size distribution. At the employed flow conditions, the real cut-off value was revealed to be about one third with respect to the filter nominal porosity in both stations. The size distribution plots showed a bimodal distribution with a mode centered around 0.22 microm in both the sites and a second broader mode which is centered between 0.3 microm and 1.2 microm diameter at Terra Nova Bay and shifted toward higher values (centred around 1.0 microm diameter) at Dome C. Each filter was analysed for the main and trace ionic components allowing evaluation of the contributions of primary and secondary aerosol sources at the two sites as a function of the particle size class. The coastal site is mainly affected by primary and secondary marine inputs: the sea spray contribution (Na+, Mg2+, Cl- and ssSO4(2-)) is dominant (77% w/w) in the coarse fraction whereas the biogenic source (methanesulfonate and nssSO4(2-)) prevails (67.5% w/w) in the fine fraction. In this fraction a significant contribution (15.5% w/w) is provided by ammonium likely to be related to surrounding penguin colonies. Dome C atmosphere is characterised by fine particles arising from secondary sources and long-range transport processes. The main component in the fine and coarse fractions at Dome C is sulfate whose nssSO4(2-) represents the 99.5% and the 92.3%(w/w) in fine and coarse fraction, respectively. The observed agreement between nssSO4(2-) and methanesulfonate temporal profiles in the fine fraction demonstrates that biogenic emissions dominate the inland background aerosol. Results from the sampling by the 8-stage impactor at Dome C are presented here: chloride and nitrate are mainly deposited on the 10-2.1 microm stages while the highest sulfate concentration was found in the submicrometric fraction which turned out to be the most acidic. Such a distribution is able to prevent nitrate and chloride re-emission as gaseous HCl and HNO3 in the 10-2.1 microm stages, arising from the exchange reaction between chloride and nitrate salts and sulfuric acid. Moreover, the concentration peak observed for nitrate in coarser fractions is probably related also to the formation of hygroscopic NH4NO3 particles and nitrate adsorption on sea salt particles.

Abstract
UNLABELLED A case of chronic eosinophilic ascites with onset in early infancy is described. An intensive diagnostic work-up ruled out other known causes of ascites in childhood. The final diagnosis was made at 2 years of age when a large number of eosinophils was detected in the ascitic fluid. The outcome was complicated by an ex vacuo intraperitoneal haemorrhage. Steroids were able to control the disease only after complete aspiration (1600 ml) of the ascitic fluid. On discontinuation of treatment, peritoneal inflammation recurred indicating steroid-dependency. CONCLUSION eosinophilic ascites, a very rare disorder in children, should be considered in the differential diagnosis of even very young children presenting with ascites.

Abstract
First-level in vitro diagnostic tests for specific IgE against common inhalant or food allergens have been used to identify allergic patients. We evaluated the performance of Phadiatop and Fx5 (mixed food allergens) serological tests (Pharmacia Diagnostics AB, Uppsala, Sweden) in different groups of pediatric patients. We studied two groups of pediatric patients: 61 children recruited from an Allergy and Clinical Immunology Unit (Group 1); 136 children from a Pediatric Unit not specifically devoted to allergic diseases (Group 2); the two groups comprised patients with (A) or without (B) clinical suspicion of allergic disease. Sera were collected from routine blood analysis. Frequencies of positivities for Phadiatop and/or Fx5 were very high (68.8%) in Group 1, however, as many as 35.5% of Group 2 children were positive, as well. All the patients of Group 1 with clinical suspicion of allergic disease (1A), confirmed by allergologic diagnostic tests, had a positive first-level test; 42.8% only of the patients in Group 2 with suspicion of allergic disease (2A) had a positive first-level test. None of the Phadiatop/Fx5-negative children of Group 2A had specific-IgE with conventional tests. In 30% of children not suspected for allergic diseases (1B and 2B), positive first-level tests were observed. Such unexpected positivities were confirmed by single specific-IgE assays in 94.7% (for inhalants) or 71% (for foods) of cases. In conclusion, altogether the sensitivity and overall performance of first-level tests in pediatric populations (especially for inhalant allergens) may suggest their use, under appropriate circumstances, both as a first diagnostic approach (to rule out negative patients) and for screening purposes.

Abstract
AIM To asses the efficacy and safety of ciclosporin in a paediatric population with inflammatory bowel disease. PATIENTS AND METHODS Twenty-three Italian children treated with ciclosporin were studied retrospectively. The indications for treatment were severe unresponsive colitis, chronic active colitis or severe fistulizing Crohn's disease. The treatment duration, follow-up and causes of drug discontinuation were assessed. RESULTS Sixteen patients were treated intravenously for a mean time of 10 +/- 7 days (1-24 days) and 19 orally for a mean time of 133 days (17-660 days). The mean follow-up of all patients was 13.2 months. Ciclosporin was totally ineffective, being discontinued for surgery, in nine of 23 patients (39%); it was discontinued for partial response in three patients (13%). During treatment, clinical remission was achieved in eight children (35%) and maintained after drug withdrawal in four (17%). In severe unresponsive colitis, urgent colectomy was avoided in 12 (85%) of 14 patients who tolerated the drug. Side-effects appeared in six of 23 patients (26%), and three (13%) required ciclosporin to be discontinued due to neurotoxicity. CONCLUSIONS Ciclosporin shows disappointing long-term results in the treatment of refractory inflammatory bowel disease, but can play an important role in preventing urgent surgery in unresponsive severe colitis. Severe side-effects can occur.

Abstract
AIM To evaluate the clinical, morphological and aetiological aspects of acute pancreatitis in children in Italy. PATIENTS The hospital records of 50 consecutive patients with acute pancreatitis observed in 5 Italian Pediatric Departments were reviewed. RESULTS A total of 25 males and 25 females (median age 10.5 years, range 2-17) were studied. Of these patients, 48 (96%) had abdominal pain. The pancreatitis was associated with biliary disease in 10 patients (20%); it was due to viral infection in 6 patients (12%), pancreatic duct abnormalities in 4 (8%, familial chronic pancreatitis in 3 (6%), trauma in 5 (10%) and other causes in 5 (10%); the pancreatitis was of unknown origin in 17 patients (34%). Previous attacks of the disease had occurred in 14 patients. A diagnosis of mild pancreatitis was made in 41 patients (82%) and of severe disease in 9 (18%). One patient with severe pancreatitis died from multiorgan failure. Patients with severe pancreatitis had significantly higher serum concentrations of C-reactive protein than patients with mild pancreatitis. Hospital stay was similar for patients with the mild form and those with the severe form of the disease. CONCLUSIONS In Italian children, acute pancreatitis is of unknown origin in about one-third of the children and is recurrent in 28% of the cases. The disease is severe in 18% of the cases.

Abstract
The immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is characterized by hypogammaglobulinemia and recurrent bacterial infections. Here we report a novel case of ICF syndrome with hypogammaglobulinemia and an inverted CD4/CD8 ratio. Cytogenetically abnormal cells,that were identified in both CD4+ and CD4- peripheral blood lymphocytes, retained their ability to proliferate in vitro following polyclonal stimulation. A primitive defect of B-cell differentiation was detected.

Abstract
AIM To obtain clinical data concerning severe attacks of ulcerative colitis in children. PATIENTS AND METHODS A retrospective chart review of 37 children with ulcerative colitis was carried out in order to assess the prevalence, risk factors, timing of presentation, and outcome of severe attacks of ulcerative colitis. RESULTS A total of 20 severe attacks occurred in 15 out of the 37 patients. No difference in the occurrence of severe attacks was detected in relation to age or disease extent at diagnosis. The mean interval between disease diagnosis and a severe attack was 9.1 months (range 0-30). Of the 20 severe attacks, 11 were resolved with medical treatment in a mean time of 1 1 +/- 4.6 days while 9 out of 20 needed urgent surgery in a mean time of 7.4 +/- 4.8 days. Of 10 out of the 15 patients who recovered from the first attack 4 required colectomy after a mean time of 6.7 months, another 4 are still in remission at a mean period of 40.7 months, one needed elective surgery after 25 months and one was lost to follow-up. CONCLUSIONS Severe attacks of ulcerative colitis had a high prevalence rate [40%); age and disease extent at presentation were not predictors of their occurrence. Approximately half the attacks resolved with medical treatment alone, while the other half required emergency surgery. After successful medical treatment of the first attack, 40% of children maintained long-term remission, while 40% required early colectomy

Abstract
We report the case of a girl with a severe perianal fistulizing Crohn's disease who during intravenous infusion of cyclosporine developed headache, general seizures and cortical blindness. Head magnetic resonance imaging showed spread, cortical-subcortical nonenhancing signal changes. Full neurological recovery was achieved in 24 hours. Cyclosporine was stopped and a single dose of infliximab was infused with rapid improvement of the fistula that at 7 months' follow-up is still closed.

Abstract
Anatomical, behavioral, histological, endocrinological, and cytogenetic characteristics were determined in a horned intersex goat. Histology of the gonads confirmed that the goat was a true hermaphrodite. Cytogenetic analysis showed that it was a chimera (60XX/60XY). Use of laparoscopy allowed determination of characteristics of the internal gonads.
