Abstract
PURPOSE The current randomized, double-blind, placebo-controlled clinical trial addressed the effects on penile erectile function of relatively high daily oral doses (6 g/day) of L-ARG for 3 months (N = 51) compared to placebo (N = 47), in patients with vasculogenic ED, with comparison between mild-moderate and severe vasculogenic ED. METHODS The outcome measures included IIEF-6 score and cavernous arteries peak systolic flow velocity (PSV) at dynamic penile duplex ultrasonography (PDU). RESULTS L-ARG supplementation for 3 months significantly increased IIEF-6 score in the overall cohort (p < 0.0001) and in subgroups of patients with mild-moderate (p < 0.0001) and severe (p = 0.007) vasculogenic ED; PSV was significantly increased in the overall cohort (p < 0.0001) and in patients with mild-moderate (p < 0.0001), but not severe vasculogenic ED. At study completion, 74% of patients improved ED degree category, although only 24% of patients, mainly belonging to the baseline category of mild ED, reached IIEF-6 scores compatible with absence of ED; moreover, 20% of patients, exclusively belonging to the baseline category of mild-moderate vasculogenic ED, reached PSV values compatible with absence of ED. CONCLUSION The results of the current study demonstrated that supplementation with relatively high doses of L-ARG as a single compound for 3 months significantly improved penile erectile function, assessed by both IIEF-6 score and PSV at dynamic PDU in patients with mild-moderate, and improved IIEF-6 score, but not PSV, in patients with severe vasculogenic ED, therefore suggesting that L-ARG might be an alternative treatment in mild-moderate vasculogenic ED patients experiencing adverse effects or with contraindications for chronic treatment with PDE5i compounds.

Abstract
Abstract
Aims
To evaluate to role of bisoprolol to control symptoms and left ventricular outflow tract obstruction (LVOTO) in a consecutive cohort of adults with hypertrophic cardiomyopathy (HCM).
Methods and results
In this retrospective study, patients with HCM with an LVOT gradient ≥50mmHg after Valsalva manoeuvre and New York Heart Association (NYHA) class II-III symptoms were assigned to receive bisoprolol (starting at 1.25 mg daily). The initial dose was increased every two weeks to achieve the target in LVOT gradient <30 mmHg or the maximum tolerated dose. The primary endpoint was the achievement of a LVOT gradient <30 mmHg and ≥1 NYHA class improvement. The secondary endpoints were proportion of patients with LVOT gradient <30 mmHg or < 50 mmHg, proportion of patients with ≥1 NYHA class improvement, and change from baseline in LVOT gradient. Between December 2001 and December 2020, 92 patients were enrolled into the study. Sixteen (17%) patients on bisoprolol met the primary endpoint. Bisoprolol reduced the LVOT gradient to less than 30 mmHg in 33 (36%) patients, to less than 50 mmHg in 57 (62%), and improved NYHA class in 30 (33%). The mean reduction of LVOT gradient on bisoprolol was 28 (±14) mmHg and the percentage reduction was 42 (±21)%. In 35 (39%) patients, bisoprolol did not reduce the gradient to less than 50 mmHg requiring disopyramide and/or myectomy to achieve this goal.
Conclusions
Treatment with bisoprolol was well-tolerated and effective in relieving obstruction and improving symptoms in a significant proportion of patients with symptomatic obstructive HCM.

Abstract
Fabry disease (FD, OMIM 301500) is an X-linked lysosomal storage disease caused by pathogenic variants in the GLA gene. Cardiac involvement is common in FD and is responsible for impaired quality of life and premature death. The classic cardiac involvement is a nonobstructive form of hypertrophic cardiomyopathy, usually manifesting as concentric left ventricular hypertrophy, with subsequent arrhythmogenic intramural fibrosis. Treatment of patients with FD should be directed to prevent the disease progression to irreversible organ damage and organ failure. The aim of this review is to describe the current state of knowledge regarding cardiovascular involvement in FD, focusing on clinical and instrumental features, cardiovascular management, and targeted therapy.

Abstract
Background The aims of this study were: to investigate the capacity of the rare disease healthcare network in Campania to diagnose patients with rare diseases during the outbreak of Covid-19; and to shed light on problematic diagnoses during this period. Methods To describe the impact of the Covid-19 pandemic on the diagnosis of patients with rare diseases, a retrospective analysis of the Campania Region Rare Disease Registry was performed. A tailored questionnaire was sent to rare disease experts to investigate major issues during the emergency period. Results Prevalence of new diagnoses of rare disease in March and April 2020 was significantly lower than in 2019 (117 versus 317, P < 0.001 and 37 versus 349, P < 0.001, respectively) and 2018 (117 versus 389, P < 0.001 and 37 versus 282, P < 0.001, respectively). Eighty-two among 98 rare disease experts completed the questionnaire. Diagnostic success (95%), access to diagnosis (80%) and follow-up (72%), lack of Personal Protective Equipment (60%), lack of Covid-19 guidelines (50%) and the need for home therapy (78%) were the most important issues raised during Covid-19 outbreak. Conclusions This study describes the effects of the Covid-19 outbreak on the diagnosis of rare disease in a single Italian region and investigates potential issues of diagnosis and management during this period.

Abstract
BACKGROUND Bromelain (BR) is a cysteine protease with inhibitory effects on intestinal secretion and inflammation. However, its effects on intestinal motility are largely unexplored. Thus, we investigated the effect of this plant-derived compound on intestinal contractility and transit in mice. METHODS Contractility in vitro was evaluated by stimulating the mouse isolated ileum, in an organ bath, with acetylcholine, barium chloride, or electrical field stimulation. Motility in vivo was measured by evaluating the distribution of an orally administered fluorescent marker along the small intestine. Transit was also evaluated in pathophysiologic states induced by the pro-inflammatory compound croton oil or by the diabetogenic agent streptozotocin. KEY RESULTS Bromelain inhibited the contractions induced by different spasmogenic compounds in the mouse ileum with similar potency. The antispasmodic effect was reduced or counteracted by the proteolytic enzyme inhibitor, gabexate (15 × 10(-6) mol L(-1) ), protease-activated receptor-2 (PAR-2) antagonist, N(1) -3-methylbutyryl-N(4) -6-aminohexanoyl-piperazine (10(-4) mol L(-1) ), phospholipase C (PLC) inhibitor, neomycin (3 × 10(-3) mol L(-1) ), and phosphodiesterase 4 (PDE4) inhibitor, rolipram (10(-6) mol L(-1) ). In vivo, BR preferentially inhibited motility in pathophysiologic states in a PAR-2-antagonist-sensitive manner. CONCLUSIONS & INFERENCES Our data suggest that BR inhibits intestinal motility - preferentially in pathophysiologic conditions - with a mechanism possibly involving membrane PAR-2 and PLC and PDE4 as intracellular signals. Bromelain could be a lead compound for the development of new drugs, able to normalize the intestinal motility in inflammation and diabetes.

Abstract
BACKGROUND Acne vulgaris is a complex, chronic, and common skin disorder of pilosebaceous units. The major pathogenic factors involved are ductal hyperkeratinization, obstruction of sebaceous follicles resulting from abnormal keratinization of the infundibular epithelium, stimulation of sebaceous gland secretion by androgens, and microbial colonization of pilosebaceous units by Propionibacterium acnes, which promotes perifollicular inflammation. AIM The aim of the study was to investigate the therapeutic effects of resveratrol, a natural phytoalexin produced by some spermatophytes, such as grapes and other plants, on acneic skin. METHODS Resveratrol was incorporated in a carboxymethylcellulose-based gel. The chemical stability of resveratrol after storage at 4°C for 30 days was investigated by high-performance liquid chromatography (HPLC). The resveratrol-containing hydrogel was administered to 20 patients affected by acne vulgaris enrolled in this single-blind study. The resveratrol-containing formulation was applied daily as a solo treatment on the right side of the face for 60 days, while the hydrogel vehicle was applied to the left side of the face as a control. To objectively evaluate the results, a digital photographic database was used to collect images. The number and type of lesions were recorded for each patient, to compare the Global Acne Grading System (GAGS) score before treatment with that obtained at the end of the study. Moreover, with the innovative technique of follicular biopsy, areas of acneic skin were prepared for histopathology. The average area occupied by microcomedones at baseline was compared with that at the end of treatment. RESULTS HPLC analysis demonstrated that resveratrol, upon incorporation into the gel, did not convert to its cis-isomer when stored at 4°C for 30 days. All patients were satisfied with the active treatment and none experienced adverse effects. Clinical evaluation showed a 53.75% mean reduction in the GAGS score on the resveratrol-treated sides of the face compared with 6.10% on the vehicle-treated sides of the face. These data were supported by histologic analysis, which showed a 66.7% mean reduction in the average area of microcomedones on the resveratrol-treated sides of the face. The comparison with the vehicle-treated side of the face (9.7% reduction) showed a clinically relevant and statistically significant decrease of lesions in areas treated with resveratrol-containing hydrogel. CONCLUSION This pilot study showed positive results for resveratrol gel in acne, and should be considered a valid starting point for further testing of the effectiveness of this molecule in different concentrations and formulations and in a larger group of patients.

Abstract
In the last decade, there has been an increased awareness that secondary metabolites produced by marine diatoms negatively impact the reproductive success of their principal predators, the copepods. Several oxylipins, products of the enzymatic oxidation of fatty acids, are produced when these unicellular algae are damaged, as occurs during grazing. In the past, the dinoflagellate Prorocentrum minimum, which does not produce the oxylipin 2-trans,4-trans-decadienal (DD), has been used as a live carrier to calculate daily ingestion rates of this molecule by copepod crustaceans. However, since the interaction between oxylipins and live carriers is unknown, the question as to how much and for how long ingestion of these molecules affects copepod reproduction remains a critical point to understanding the functional role of such compounds at sea. In the investigation presented here we used giant liposomes ( approximately 7 mum) as a delivery system for the oxylipin DD, prepared in the same size range as copepod food and containing known amounts of DD. The aim of this work was to relate the ingestion of DD to the reproductive failure of the copepods Temora stylifera and Calanus helgolandicus. Liposomes were very stable over time and after 10 days of feeding, liposomes encapsulating DD reduced egg hatching success and female survival with a concomitant appearance of apoptosis in both copepod embryos and female tissues. Concentrations of DD inducing blockage were one order of magnitude lower that those used in classical feeding experiments demonstrating that liposomes are a useful tool to quantitatively analyze the impact of toxins on copepods.

Abstract
We report on three infants with congenital chylothorax (CC) and congenital pulmonary lymphangiectasia (CPL). CPL appears to be a characteristic pathological finding in CC. Through the use of lymphoscintigraphy and computed tomography, this study suggests that CC and CPL are strongly correlated entities and that the dysplasia of the lymphatic system results in a pulmonary lymphatic obstruction sequence. The initial microscopic dilatation of the lymph channels may lead to progressive weeping of lymphatics and, consequently, to pleural effusion. Non-Immune Hydrops Fetalis (NIHF) may be the final consequence of impaired systemic venous return and may help to explain pleural-pulmonary involvement in this generalized lymph-vessel malformation syndrome.

Abstract
In the last few years, a variety of experimental and clinical studies concerning the formation, metabolism, and cellular effects of cholesterol oxidation products (COPs) have been carried out. Nevertheless, a substantial lack of knowledge exists regarding the possible intake of these compounds by the newborn through human and/or adapted formula milk. As far as the pathological role of COPs is concerned, exhaustive studies have shown that since dietary COPs are cytotoxic and atherotoxic, they may lead to adverse effects on health. The aim of this study was to investigate the possible development of cholesterol oxidation in adapted formula and in human milk by comparing the main cholesterol oxidation biomarker (7-ketocholesterol) concentration in both. To do so, the total (bonded and free) 7-ketocholesterol content was measured in ten fresh human mature milk samples and in ten milk adapted formula samples by high performance liquid chromatography and diode array detection. The 7-ketocholesterol human milk content (0.7+/-0.3) was often below the quantifiable limit (0.5 microg/g of extracted lipids) while 7-ketocholesterol adapted milk concentrations were often above (3.6+/-4.0) this limit. The 7-ketocholesterol content of adapted formula samples was significantly higher as compared to human milk samples (P<0.05). This is the first study to provide data concerning the concentrations of cholesterol oxides in human milk and in formula milk. Our results clearly suggest that the manufacturing technologies employed and the nutrient extractive sources play a crucial role in the development of cholesterol oxides in the end product. Careful surveillance has to be paid in order to avoid alteration of bioactive properties of nutrients and/or development of potentially toxic derivative compounds.

Abstract
AIMS/HYPOTHESIS The pathogenesis of permanent diabetes mellitus diagnosed early in life is heterogeneous and, in most cases, not known. We aimed at identifying markers differentiating between non-autoimmune and autoimmune diabetes. METHODS The clinical, genetic and epidemiological features of 111 diabetic patients (62 males) who received insulin within 12 months of life were studied. RESULTS The epidemic curve by age of diabetes onset revealed two subsets of patients at a cutoff of 180 days. In the group with diabetes onset before 180 days ("early onset" permanent diabetes) the analysis of HLA susceptibility heterodimers (available for 21 individuals) showed that 76% had a "protective" HLA genotype for Type I (insulin-dependent) diabetes mellitus as compared to 11.9% (5/42) of the later onset group. Accordingly, "early onset" children were less likely to have autoimmunity markers (4 out of 26 tested) than children with onset after 180 days (13 out 20 tested) (15.4% vs. 65.0%, p<0.01). Of note, 19 out of 20 (or the 95%) patients who were born on the island of Sardinia, an Italian region where the incidence of Type I diabetes is six times higher than continental Italy (33/100,000/year vs 5/100,000/year), were included in the later onset group (>180 days). Small-for-date birthweight, a possible sign of reduced foetal insulin secretion, was more common in the "early onset" group (OR=9.9, 95%-CI 2.6-38.6). CONCLUSION/INTERPRETATION These results, obtained in the largest population-based cohort of diabetic infants hitherto reported, suggest that "early onset" permanent diabetes cases differ from later onset cases and that most of them do not have an autoimmune pathogenesis.

Abstract
We describe two newborn brothers with a pattern of malformation characterized by the persistence of Müllerian duct derivatives, intestinal lymphangiectasia, hypertrophied alveolar ridges, and early death. Postmortem examination showed the presence of a rudimentary uterus, fallopian tubes, the upper third of a vagina, a prostate of normal shape, a dilated colon, and generalized intestinal and pulmonary lymphangiectasia. The syndrome was first delineated by Urioste and co-workers [1993: Am J Med Genet 47:494-503]. These cases confirm the existence of a definite and distinct entity.

Abstract
A computer software package was developed to perform the calculation involved in compounding total and partial parenteral nutrition for low-birth-weight and sick newborns. The program requires a minimum of user input and is menu-driven. The flexibility of the algorithm has been increased to a considerable degree. The program calculates the overall balance of fluids, nutrients, calories, electrolytes and minerals. It allows for the possibility of total parenteral nutrition and simultaneous oral feeding. Nutrient amounts per Kg per day and combination of enteral food and parenteral infusions can be completely changed by the operator. In our experience computer-assisted system was more efficient than a manual system and the possibility of computational error was reduced.

Abstract
BACKGROUND It has been largely shown that during the first month of life, in the preterm neonate Hb levels and Hct percentages rapidly decrease, high HbF concentration persists and a high oxygen affinity occurs. Data are needed to establish the level at which 2,3 dyphosphoglycerate (2,3 DPG) interacts with the regulation of oxygen affinity. SUBJECTS AND METHODS 24 samples, from eight uncomplicated preterm newborns (34.1 +/- 1.83 GW, 1869 +/- +/- 291 BW) obtained at the same time as those required for the clinical management of the infants, were collected on the 2nd, 7th and 14th day of life. Blood gases, total hemoglobin and hematocrit were obtained from 0.3 ml arterialised capillary blood. Assays of 2,3 DPG were made separately on 0.4 ml venous blood. RESULTS As expected tHb concentration and Hct percentages significantly decreased from day 2 to day 14 in all eight cases. On the contrary 2,3 DPG and p50 values remained stable. Subsequently throughout the study period all neonates had an increased 2,3 DPG/Hb ratio that was significantly related with p50 at standard conditions (p < 0.05). CONCLUSIONS Stable 2,3 DPG concentrations during all study period have been detected. The subsequent significant increased 2.3 DPG/Hb, ratio related to increased p50 values, could have a key role in a physiological mechanism aimed to ensure adequate oxygen delivery to the tissues and to counteract the higher oxygen affinity of fetal hemoglobin. A wider sample is needed to validate this hypothesis.

Abstract
OBJECTIVE To compare the effectiveness of the Infant Flow Driver (IFD) with single prong nasal continuous positive airway pressure (nCPAP) in preterm neonates affected by respiratory distress syndrome. DESIGN Randomised controlled study. PATIENTS Between September 1997 and March 1999, 36 preterm infants who were eligible for CPAP treatment were randomly selected for either nCPAP or IFD and studied prospectively for changes in oxygen requirement and/or respiratory rate. The requirement for mechanical ventilation, complications of treatment, and effects on mid-term outcome were also evaluated. RESULTS Use of the IFD had a significantly beneficial effect on both oxygen requirement and respiratory rate (p < 0.0001) when compared with nCPAP. Moreover, O(2) requirement and respiratory rate were significantly decreased by four hours (p < 0.001 and p < 0.03 respectively). The probability of remaining supplementary oxygen free over the first 48 hours of treatment was significantly higher in patients treated with the IFD than with nCPAP (p < 0.02). IFD treated patients had a higher success (weaning) rate (94% v 72 %) and shorter duration of treatment (49.3 (31) v 56 (29.7) hours respectively; mean (SD)), although the difference was not significant. CONCLUSIONS IFD appears to be a feasible device for managing respiratory distress syndrome in preterm infants, and benefits may be had with regard to oxygen requirement and respiratory rate when compared with nCPAP. The trend towards reduced requirement for mechanical ventilation, shorter clinical recovery time, and shorter duration of treatment requires further evaluation in a multicentre randomised clinical trial.

Abstract
To determine whether human X-linked neonatal diabetes mellitus, enteropathy and endocrinopathy syndrome (IPEX; MIM 304930) is the genetic equivalent of the scurfy (sf) mouse, we sequenced the human ortholog (FOXP3) of the gene mutated in scurfy mice (Foxp3), in IPEX patients. We found four non-polymorphic mutations. Each mutation affects the forkhead/winged-helix domain of the scurfin protein, indicating that the mutations may disrupt critical DNA interactions.

Abstract
We report a newborn admitted to our service on the 2nd day of life because of hypotonia and metabolic acidosis. A progressive hepatocellular dysfunction dominated the clinical picture and the patient died at 13 months of age because of severe hepatic failure. Persistent lactic acidosis, high ketone bodies levels and high-normal lactate/pyruvate and 3-hydroxybutyrate/acetoacetate molar ratios in plasma were found. Investigation of a liver biopsy revealed low activities of all the mitochondrial respiratory chain enzymes but in particular a marked decrease of complex I (NADH cytochrome c reductase) activity. All respiratory chain enzyme activities were normal in cultured skin fibroblasts. Mitochondrial DNA analysis failed to detect any major rearrangements. Although only a few cases have been reported so far, it is becoming clear that liver should be considered as one of the organs involved in oxidative phosphorylation disorders. The finding of unexplained progressive liver failure with poor neurological conditions, lactic acidaemia and ketonuria strongly warrants investigation for a respiratory chain disorder. Moreover, the finding of normal respiratory enzyme activities in a tissue other than liver does not rule out the existence of an oxidative phosphorylation disorder in patients with hepatocellular disease of unexplained origin.

Abstract
Three female patients with a previously poorly controlled Insulin Dependent Diabetes Mellitus (IDDM), without evidence of cardiovascular, hepatic or renal dysfunction, developed generalized edema after a substantial increase in their insulin dosage. Edema resolved in 2-3 weeks, without specific therapy. Our patient's findings met the criteria of diagnosis of insulin edema. Insulin edema during IDDM is an uncommon complication of insulin therapy (1/400) and its pathogenesis is not clarified so far; it is a transient and self-limiting condition. The diagnosis is based on exclusion of all other major causes of edema.

Abstract
OBJECTIVE To assess updated incidence of insulin-dependent diabetes mellitus (IDDM) in 0- to 14-year-old children in Liguria, a northwest region of Italy. RESEARCH DESIGN AND METHODS Incident cases were recorded prospectively from 1987 to 1991. Incidence rates (IRs) were directly standardized on the basis of the 1990 world population. The independent effect of age, sex, residence, and calendar year was estimated with a Poisson regression model. The degree of ascertainment was calculated in accordance with the capture/recapture method. RESULTS During 5 full calendar years, 117 new cases of IDDM in children were diagnosed in Liguria. The standardized IR over the 5-year period was 11.72 cases.100,000(-1).year-1. The sex-specific IR among males and females was 11.45 and 12.01, respectively. The age-specific IR was higher in the 5-9 age-group. CONCLUSIONS The IR of IDDM in Liguria is among the highest in southern Europe and approaches that of northern European countries. In particular, it is much higher than those reported in the surrounding Italian regions, except for Sardinia. Therefore, the geographical distribution of IDDM does not seem to reflect the simple north-south gradient reported in several previous studies.
