Tele-medicine versus face-to-face consultation in Endocrine Outpatients Clinic during COVID-19 outbreak: a single-center experience during the lockdown period.

CONTEXT: The COVID-19 outbreak in Italy is the major concern of Public Health in 2020: measures of containment were progressively expanded, limiting Outpatients' visit. OBJECTIVE: We have developed and applied an emergency plan, tailored for Outpatients with endocrine diseases. DESIGN: Cross-sectional study from March to May 2020. SETTING: Referral University-Hospital center. PATIENTS: 1262 patients in 8 weeks. INTERVENTIONS: The emergency plan is based upon the endocrine triage, the stay-safe procedures and the tele-Endo. During endocrine triage every patient was contacted by phone to assess health status and define if the visit will be performed face-to-face (F2F) or by tele-Medicine (tele-Endo). In case of F2F, targeted stay-safe procedures have been adopted. Tele-Endo, performed by phone and email, is dedicated to COVID-19-infected patients, to elderly or frail people, or to those with a stable disease. MAIN OUTCOME MEASURE: To assess efficacy of the emergency plan to continue the follow-up of Outpatients. RESULTS: The number of visits cancelled after endocrine triage (9%) is lower than that cancelled independently by the patients (37%, p < 0.001); the latter reduced from 47 to 19% during the weeks of lockdown (p = 0.032). 86% of patients contacted by endocrine-triage received a clinical response (F2F and tele-Endo visits). F2F visit was offered especially to young patients; tele-Endo was applied to 63% of geriatric patients (p < 0.001), visits' outcome was similar between young and aged patients. CONCLUSIONS: The emergency plan respects the WHO recommendations to limit viral spread and is useful to continue follow-up for outpatients with endocrine diseases.

SERUM AND BAL YKL-40 LEVELS IN DIFFERENT INFLAMMATORY LUNG DISEASES: AN UPDATE.

YKL-40 (also called chitinase 3-like-1 or human cartilage glycoprotein 39) is a chitinase-like protein belonging to the family 18 of glycosyl hydrolase (GH18). This protein is involved in the inflammatory process acting as pro-inflammatory cytokine secreted by neutrophils, activated human macrophages, vascular smooth muscle cells and cancer cells. It has been shown that YKL-40 has a role in pathological tissue remodeling and development of fibrosis of several diseases. To date, the biological and pathophysiological function of YKL-40 protein in pulmonary diseases is still unclear. This review focuses on the role of YKL-40 in diagnosis and monitoring of different lung diseases in order to assess whether this protein could be used as biomarker of specific conditions featured by inflammation and fibrosis. A comprehensive review of the literature using PubMed database, with appropriate terms, was undertaken for articles in English published since 1997. The literature search was undertaken in October 2014.

RELATION OF BODY MASS INDEX WITH IgE LEVELS, ALLERGIC SENSITIZATION AND LUNG FUNCTION IN ASTHMATIC CHILDREN: OUR EXPERIENCE AND REVISION OF LITERATURE.

In recent decades, there has been an increase in the prevalence of asthma and obesity in pediatric age. In this regard several studies have provided controversial data to demonstrate the link between Body Mass Index (BMI) and asthma, both in adults and in children. In this prospective study we evaluated the relationship between body mass index value, total IgE immunoglobulin E levels, skin prick test (SPT) sensitization and lung function in children affected by asthma. According to the analysis of data on the comparison of normal-weight patients versus overweight/obese patients, there was no significant difference in the values of FEV1 (86%±12 vs 90%±19), FVC (81%±11 vs 88%±18), skin prick tests (22.72% vs 36.66%) and total IgE values (192.22±368.28 vs 503±914.04). We carried out a sub-analysis to study the difference between three groups of patients: normal weight, overweight and obese. Obese patients showed higher total IgE values than normal-weight patients with a statistically significant difference. Conversely, there was no significant difference between the normal weight group and the obese group in the respiratory function tests and the SPT. Moreover, we found a higher value of total IgE in female overweight/obese compared with normal weight, while there was no significant difference in relation to parameters of lung function and SPT. However, the same analysis in the male sample did not show any statistically significant difference. This study confirms the higher incidence of atopy in obese children, especially in female gender, but not a direct relationship with either allergens sensitization or abnormal lung function.

Clinical and molecular markers of chronic interstitial nephropathy in congenital unilateral ureteropelvic junction obstruction.

PURPOSE: We evaluated clinical and biological variables, and their meaning as reliable markers of chronic interstitial nephropathy in a selected group of children with prenatally detected hydronephrosis who underwent pyeloplasty because of congenital unilateral ureteropelvic junction obstruction. MATERIALS AND METHODS: We reviewed the clinical, prenatal and postnatal ultrasonographic, and scintigraphic records of children for whom intraoperative biopsy records were available. We performed histological analysis, and evaluated tubulointerstitial immunostaining for vimentin and alpha-smooth muscle actin, and the immunohistochemical and mRNA expression of the renin-angiotensin system peptides and transforming growth factor-beta1. RESULTS: The children were divided in 2 groups according to the absence (group 1) or presence (group 2) of chronic interstitial nephropathy in the biopsy. Patients in group 2 were significantly younger at prenatal diagnosis (p = 0.031), and had decreased split renal function (p = 0.005) and worse drainage (p = 0.035) on preoperative diuretic renography. No differences were found in terms of degree of hydronephrosis, or its prenatal and postnatal variation. Group 2 biopsies exhibited greater immunostaining for alpha-smooth muscle actin and vimentin (p = 0.004 and p = 0.047, respectively), and transforming growth factor-beta1 mRNA levels (p = 0.06). Vimentin and alpha-smooth muscle actin positivity correlated with renin, angiotensin II receptors 1 and 2, and transforming growth factor-beta1 mRNA levels, and all correlated with preoperative split renal function and post-void washout. CONCLUSIONS: In congenital unilateral ureteropelvic junction obstruction chronic interstitial nephropathy and poor postoperative recovery seem to be associated with an earlier diagnosis of hydronephrosis, functional loss greater than 10% and worse scintigraphic drainage. Moreover, there is a strong correlation between molecular fibrogenic markers and histologically and scintigraphically demonstrated renal damage.

Platelet cGMP inversely correlates with age in healthy subjects.

Biochemical modifications associated with the increase in platelet activity with age are not well defined. Furthermore it is well known that the nitric oxide/cyclic 3', 5'-guanosine monophosphate (cGMP) pathway regulates platelet aggregation. The aim of the present study was to examine the relationship between platelet content of cGMP and age. 120 normal subjects, evaluating the cGMP platelet concentration, 17betaE2, IGF-I, dehydroepiandrosterone sulphate (DHEAS), insulin, plasma glucose, lipid pattern, homocysteine and PAI-I antigen, were studied. The multivariate analysis in a model with cGMP as dependent variable and with age, LDL, apolipoprotein B (ApoB), DHEAS, E2 and insulin-like growth factor (IGF)-I as independent variables shows a negative correlation between cGMP and age (p<0.01, beta=-0.388). In conclusion our data suggest that the reduced efficiency of the system constitutive nitric oxide synthase (cNOS)/guanylate cyclase represents at least one of the reasons of the increased platelet aggregability with age.

Kidney transplantation in children with reconstructed bladder.

There is some controversy about the safety of renal transplantation in patients with an augmentation cystoplasty because of the possibility of urinary tract infection in immunosuppressed patients leading to pyelonephritis and graft loss. Nevertheless, it is now well known that in patients with a small volume and poorly compliant bladder, reconstructive bladder surgery (augmentation cystoplasty or continent reservoir) creates a low-pressure and compliant reservoir, which protects the upper urinary tract and restores a functional lower urinary tract. Graft survival is not adversely affected when a kidney transplant is drained into a reconstructed bladder. When bowel segments are used for augmentation, a voiding modality with clean intermittent self-catheterization does not increase the risk of urinary tract infections, even in immunosuppressed patients.

No evidence of fluid absorption during continuous low-pressure transurethral resection of the prostate: assessment by measuring expiratory breath ethanol concentrations.

OBJECTIVE: Measurement of the ethanol concentration in expired breath during transurethral resection of the prostate (TURP). METHODS: TURP is a noninvasive method to estimate the amount of irrigant absorbed. The expiratory breath ethanol concentrations (EBEC) were measured with a standard alcohol breath analyzer in 35 patients in the course of TURP. All interventions were performed with a 27-french continuous flow resectoscope using a solution of 1. 5% glycine + 1% ethanol as irrigating fluid. Serum sodium and osmolality were measured pre- and postoperatively. No patient developed signs of transurethral resection syndrome; no significant changes in serum sodium, osmolality and EBEC were found throughout the operation. CONCLUSION: Absorption of irrigant fluid during TURP with continuous low-pressure irrigation seems to be extremely slight (if not absent) as measured by expired breath ethanol method.

[Acute encephalitis: study of a childhood case load]. / Encefaliti acute: studio di una casistica pediatrica.

Twenty patients with viral encephalitis were studied retrospectively. Among these, in 2 cases, it was possible to formulate the diagnosis of encephalitis with viral replication by herpes virus on the basis of finding of cerebrospinal fluid IgM, serum and/or cerebrospinal fluid specific antibody rate movement and TC-scan necrotic lesions in typical sites. In 18 of 20 patients it was formulated the generic diagnosis of encephalitis without evidence of viral replication. Among these last 18 patients, 7 were considered affected by post-infective encephalitis on the basis of the anamnestic finding of the causing disease within 30 days from the appearance of the first symptoms. Into the 11 other the etiology was anamnestically hidden. The outcome was essentially favourable in the considered cases (16/20 complete recoveries). Poor outcome factors were considered the presence of herpetic infection and TC-scan alterations into the group of encephalitis without evidence of viral replication in association of anamnestic finding of measles.

Sex pheromone components of the European goat moth,Cossus cossus.

Female tip washings of the European goat moth,Cossus cossus L., were found to contain the following compounds that are structurally similar to known pheromone components of Lepidoptera (%): decyl acetate (1.5), (Z)-5-dodecenol (1), (Z)-5-dodecenyl acetate (66), dodecyl acetate (12), (Z)-5-tetradecenyl acetate (14), tetradecyl acetate (4), and hexadecyl acetate (1.5). The washes contained an average of 125 ng of (Z)-5-dodecenyl acetate per female equivalent. EAG responses to nanogram amounts of the identified products indicated that (Z)-5-dodecenyl acetate was the most potent olfactory stimulant followed by (Z)-5-tetradecenyl acetate and (Z)-5-dodecenol, whereas the saturated acetates caused only weak depolarization. A strong EAG response was also recorded for (Z)-3-decenyl acetate, which was not detected in the female tip washings. Field results showed that (Z)-5-dodecenyl acetate was essential for the attraction of the males and that (Z)-3-decenyl acetate improved the attractiveness of (Z)-5-dodecenyl acetate alone or in combination with (Z)-5-tetradecenyl acetate.
