Abstract
BACKGROUND Severe alpha1-antitrypsin (AAT) deficiency (AATD) is associated with a high risk of airflow obstruction and emphysema. The risk of lung disease in those with intermediate AAT deficiency is unclear. Our aims were to compare pulmonary function, time of onset of symptoms, and indicators of quality of life among patients with severe AATD (PI*ZZ), patients with intermediate AATD (PI*MZ) from the Italian Registry of AATD with a chronic obstructive pulmonary disease (COPD) cohort of patients without AATD (PI*MM). METHODS We considered a total of 613 patients: 330 with the PI*ZZ genotype, 183 with the PI*MZ genotype and 100 with the PI*MM genotype. Radiological exams, pulmonary function test, and measurement of quality of life have been performed on all cohorts of patients. RESULTS The three populations differ significantly in terms of age at COPD/AATD diagnosis (P=0.00001), respiratory function (FEV1, FVC, DLCO P<0.001), quality of life (P=0.0001) and smoking history (P<0.0001). PI*ZZ genotype had 24.9 times a higher likelihood of developing airflow obstruction. The MZ genotype is not associated with a significant early risk of airflow obstruction. CONCLUSIONS The comparison of populations with PI*ZZ, MZ and MM genotypes allows to delineate the role of alpha1-antitrypsin deficiency on respiratory function and on the impact on quality of life, in relation to other risk factors. These results highlight the crucial role of primary and secondary prevention on smoking habits in PI*MZ subjects and the importance of an early diagnosis.

Abstract
OBJECTIVE Anti-COVID-19 vaccines were mainly associated with non-serious adverse events (AEs), whose prevalence was reported to be up to 70% in healthcare workers (HCWs). This may lead to sick leave requests, but this impact has never been quantified. This study aimed to investigate the absence from work among HCWs following anti-COVID-19 vaccination. Its association with age and previous COVID-19 infection was also assessed. PATIENTS AND METHODS This is a retrospective observational cross-sectional study on administrative data about sick leave requests after anti-COVID-19 vaccination. All the HCWs employed at the Niguarda Hospital (Milan, Italy) who received the vaccine from December 27, 2020 to February 28, 2021 were included. RESULTS In total, 4,088 HCWs received the first dose of the vaccine and 4,043 completed the vaccination cycle. After the first injection, 1.6% of HCWs requested sick leave, while after the second injection, the number of requests significantly increased (+6.1%, p<0.001). A significant increase in sick leave was detected for those who have had SARS-CoV-2 infection after the first injection (+2.3%, p<0.001). After the second dose, a significant increase in sick leave was observed in the 20-30-year-old group compared to >30 years (+3.6%, p=0.017), if HCWs without a history of SARS-CoV-2 infection were considered. CONCLUSIONS The requests for sick leave among HCWs following the anti-COVID-19 vaccine were limited and higher after the second injection. This may help the management of the human resources when the large-scale administration of the anti-COVID-19 vaccines will involve other categories of workers.

Abstract
OBJECTIVE This study aimed to improve the post-marketing surveillance on mRNA anti-SARS-CoV-2 vaccines, characterizing the adverse events (AEs) after the first dose of mRNA BNT162b vaccine. The associations between the AEs and individuals' characteristics were explored. PATIENTS AND METHODS All adult healthcare workers at Niguarda Hospital (Milan, Italy) who were referred for the first dose of vaccine were offered to participate in a cross-sectional survey during the second-dose administration, between 18 January and 7 February 2021. All participants completed a questionnaire about age, gender, weight, height, medical history, concurrent therapies, employment status, previous diagnosis/testing for SARS-CoV-2 infection, and a list of 24 AEs (solicited AEs). The development of at least one solicited AEs was the main outcome. AEs were stratified by the presence of injection-site symptoms, systemic symptoms or both, and the differences between strata were assessed as a secondary outcome. Biometric data and reports of a previous diagnosis of SARS-CoV-2 infection were also explored, as predictors of the main outcome. RESULTS 7,014 healthcare workers were included. An incidence of 3 per 10.000 persons for serious AEs following the first administration of the mRNA BNT162b vaccine was found. An association between the development of non-serious AEs with young age, female gender, low body mass index, and previous history of SARS-CoV-2 was described. CONCLUSIONS This real-life study supported data on the safety profile of the BNT162b2 mRNA vaccine. Our findings on the associations between the development of non-serious AEs with some individual characteristics may help physicians and patients make educated and informed medical decisions towards anti-COVID-19 vaccination.

Abstract
BACKGROUND Malignant pleural mesothelioma (MPM) is a rare and aggressive malignancy that most commonly affects the pleural layers. MPM has a strong association with asbestos, mainly caused by exposure to its biopersistent fibers in at least 80% of cases. Individuals with a chronic exposure to asbestos might develop disease with a 20-40-year latency with few or no symptoms. Such has been the case in the Italian regions of Piedmont and Lombardy, where industrial production of materials laden with asbestos, mainly cements, has been responsible for the onset of a large epidemic. Since 2018, a multidisciplinary team at San Matteo hospital in Pavia has been collecting data on over 100 patients with MPM. The main goal of this project is to define and describe an integrated profile for each MPM case at diagnosis by using data mining and partition analysis. METHODS Here we bring together exhaustive epidemiologic, histologic and radiologic data of 88 MPM patients that came to our observation and draw correlations with predictive and prognostic significance. RESULTS The median overall survival (OS) was 15.6 months. Most patients presented with pleural effusion, irrespective of disease stage. Quite unexpectedly, no statistically significant association was demonstrated between OS and TNM disease stage at diagnosis. Although average OS is similar in male and female patients, partition analysis of data underlined a significant differential hierarchy of predictor categories based on patient gender. In females with no smoking history, full chemotherapeutic regimens are associated with better outcomes. Moreover, concerning second line treatments, vinorelbine emerged as the most advantageous choice for female patients, whereas in the male subgroup no statistically significant difference resulted between gemcitabine and vinorelbine. CONCLUSION A multidisciplinary approach to MPM is mandatory to define better therapeutic approaches, personalize the management and improve patient outcomes.

Abstract
Background: Malignant pleural mesothelioma (MPM) is an aggressive tumor with poor prognosis, mainly associated with work or environmental exposure to asbestos. MPM’s molecular profile is largerly unexplored and effective therapies are still lacking. MPM rarely harbours those somatic genetic lesions that usually characterize solid epithelial-derived tumors. On this basis, our study aims at investigating MPM epigenetic profile. Methods: We here assessed through immunohistochemistry, FISH and methylation specific PCR, the expression of 5-hydroxymethylcytosine (5- hmC) - an epigenetic marker and an important regulator of embryonic development and carcinogenesis - and the methylation status of the promoter of the MTAP gene - encoding for an enzyme involved in the rescue process of methionine and adenine - in two relevant series of FF-PE MPM samples derived from MPM thoracoscopic biopsies. Tissue sampling was performed at diagnosis. Results: Within the limitations of the study cohort, the 5-hmC immunophenotype was different among the histological MPM types analysed. In fact, 18% of the epithelial MPMs were negative, 47% weakly positive, and 35% of the cases showed an intense expression of 5-hmC. Sarcomatoid and biphasic MPMs showed intense 5-hmC expression pattern (positive and weakly positive in more than 80% of cases). Among MPM featuring epithelial lineage, none showed methylation of MTAP promoter. Conclusions: Mesothelial sarcomatoid tumors featured a methylation profile characterized by a permanent gene silencing. Epithelial MPM methylation profile was in-between that of sarcomatoid MPM and the one of epithelial-derived tumors. MTAP promoter methylation level cannot be considered a suitable biomarker of epithelial MPM arousal.

Abstract
Asthma, allergic rhinitis and atopic dermatitis are multifactorial disorders influenced by various familial and environmental factors. Cord blood IgE levels may be predictive for subsequent allergy onset. Serum IgE assessment has been rarely investigated. This study is aimed at evaluating serum IgE levels during the first year of life and relating to subsequent allergies. Total serum IgE levels were assessed in 102 newborns in the first days of life (2–3) and then again at 3, 5, 6, 11 and 12 months of age. After ten years, paediatricians and general practitioners caring for these children were tracked through the Local Healthcare Agency (LHA) database and asked about possible allergy of their patients, including transient ones. F Serum IgE increased in allergic infants at 1 year of life. The predictive model was significant. In conclusion, this study demonstrates that serum IgE may be predictive of subsequent allergy onset, preferably if assessed at 1 year of age.

Abstract
BACKGROUND The aim of this research is to evaluate quality of out-of-hospital medical services in our country, using performance indicators and a new computerised database. METHODS (a) EXPERIMENTAL DESIGN Data were collected prospectively in three emergency dispatch centres for 90 days. Follow-up was evaluated at 1 day and 1 month after the event. This paper presents data on the cardiac arrest cohort only. (b) SETTING Three emergency dispatch centres in Lombardia. (c) PATIENTS One hundred and seventy-eight patients in non-traumatic cardiac arrest were enrolled. (d) INTERVENTIONS None. The study was observational only. RESULTS Mean interval between phone call and arrival on scene was 8.5+/-3.5 min. BLS manoeuvres were carried out from bystanders only in 15% of the cohort; this was associated with significant mortality reduction (85.7 versus 95.8%, chi(2) P<0.05). One hundred and thirty-three patients (75%) received assistance from BLS crews while only 45 patients (25%) were assisted by ALS medical personel, with a significant mortality reduction (ALS deaths 86.7%, BLS deaths 97%). Total 24 h survival was 9% and survival at 1 month declined to 6.17%. CONCLUSIONS Quality monitoring produces objective information on interventions and outcomes. Only with this information, is it possible to implement improvement programmes that are planned according to the data presented.

Abstract
PURPOSE Cystosonography with echo contrast is an imaging modality developed to avoid x-ray exposure during detection of vesicoureteral reflux. The main role of cystosonography has been limited to screening for reflux in the female and for followup of both sexes. In males the radiographic voiding cystourethrogram is still considered the gold standard for urethral evaluation. We determined whether cystosonography during the voiding phase (voiding cystourethrosonography) can adequately visualize the male urethra and differentiate the normal from the obstructed urethra. MATERIALS AND METHODS 100 males underwent cystosonography with echo contrast to detect vesicoureteral reflux. During the voiding phase the urethra was studied with ultrasound. The transperineal sagittal approach was chosen because the bladder neck and proximal part of the urethra were better visualized with the probe maintained coaxial to these structures. In every case in which ultrasound urethral imaging was considered abnormal a radiographic voiding cystourethrogram was performed for comparison, and the urethra was directly observed with cystourethroscopy. All patients with normal urethral imaging have been followed for 12 to 54 months (mean 32). RESULTS Voiding cystourethrosonography visualized the voiding phase in all patients studied with the transperineal ultrasound approach. Of the 100 boys 8 were correctly diagnosed with posterior urethral valves. None of those with normal ultrasound imaging showed clinical signs suggestive of urethral obstruction and remained asymptomatic. CONCLUSIONS The male posterior urethra can be effectively visualized with voiding cystourethrosonography, which can differentiate normal from the pathological obstructive urethral findings. This new approach can be recommended as the primary imaging modality to detect vesicoureteral reflux for both sexes, limiting the role of conventional fluoroscopic voiding cystourethrogram only to confirmation of a pathological finding in the male patient with a suspected obstructed urethra.

Abstract
The Regional Law No. 31 of 1997 has revised the Lombardy Health Service as a whole, separating "providers", credited Public and Private Health Institutions, from "purchasers", Local Health Agencies. To this purpose, the improvement of the quality of assistance has been enhanced through an accreditation process aimed at implementing second level regional requirements considered as being necessary for carrying out effective treatment and meeting patient needs. Training, implementation and evaluation of quality service within Health Institutions have been carried out with the assistance of the Regional Observatory on the Quality of Health Service, which helped to identify initial intervention areas, define process indicators, activities and outcomes and verify patient satisfaction, all this to improve performance, reduce risks and control costs. To fully develop the Institutions in the accreditation process, the complex and difficult aspect of health care quality has been more extensively and deeply dealt with by adopting an "Excellence accreditation" model in cooperation with the Joint Commission International Accreditation and by experimenting with Professional accreditation supported by Scientific Societies to further contribute to the development of technical skills and knowledge. The Quality Project carried out so far is based on the integration of various projects, which will be the object of practical interventions by the General Health Direction. All the information and results gathered from this project will be very helpful in finding solutions that will enable all Health Institutions in Lombardy to reach an adequate level of quality.

Abstract
We describe a familial syndrome in two brothers who were investigated after the casual discovery of tubular proteinuria in their 1st month of life. During a follow-up of 20 and 11 years, respectively, the two children grew well and were asymptomatic, but developed the same biochemical abnormalities, i.e., tubular proteinuria and hyperphosphaturia, progressive decrease in serum phosphorus below the normal values for age, and an increase in serum 1,25-dihydroxyvitamin D levels over normal values. Moreover, hyperabsorptive hypercalciuria and systemic osteopenia developed and progressively worsened. In both children, at a different age, medullary nephrocalcinosis appeared. The oldest boy suffered a progressive decrease in urinary concentration ability and in glomerular filtration rate. Oral phosphate supplementation led to reversal of all biochemical abnormalities, with the exception of decreased phosphate tubular reabsorption and tubular proteinuria. With long-term phosphate supplementation, a normal bone mass was reached, while progression of nephrocalcinosis was arrested and impairment of renal function was slowed down. In a family study (siblings and parents), the only detectable abnormality was microglobinuria in the mother, thus suggesting a X-linked inheritance of this disorder. In the two probands a mutation within the renal chloride channel gene (CLCN5) was discovered.

Abstract
OBJECTIVE To determine: (i) the proportion of vesicoureteric reflux (VUR) associated with congenital renal damage and whether it can be severe enough to cause renal impairment from birth: (ii) to evaluate the distribution of males and females affected; and (iii) to describe the course of congenital damage in the first years of life. PATIENTS AND METHODS A total of 108 children (76 male and 32 female, M:F 2.3:1), whose VUR was diagnosed before any infection, were followed from birth for a mean (range) of 4.3 (1-10) years. Renal damage was defined by serum creatinine concentration, creatinine clearance and renal imaging (ultrasonography and renal scintigraphy) performed within the first month of life and periodically thereafter. RESULTS Of the 108 children, 58 had bilateral and 50 unilateral reflux (total number of refluxing units, 166). High-grade VUR (grade > or = 4) was found in 96 (58%) refluxing renal units (RRUs). Males had a prevalence of bilateral severe (> or = grade 4) reflux (M:F 5.2:1), while in those wit unilateral VUR, the M:F ration was 1.5:1. At birth, mild to moderate damage was present in 56 (36%) RRUs and only associated with VUR of grade > or = 3. Bilateral reflux of grade > or = 4 was associated with congenital moderate/severe renal failure in nine neonates (seven males). In infants with grade > or = 4 VUR who underwent surgical correction, VUR resolved in 92% of cases. In infants with VUR of grade > or = 4 followed medically, the reflux spontaneously resolved in 42% and ameliorated in 16% after 18 months. Serial renal scans during the follow-up showed no progression of renal damage. CONCLUSIONS VUR diagnosed at birth on prenatal ultrasonography is associated with congenital damage, with males affected more often than females. The damage involves both kidneys in a consistent proportion and is an important cause of chronic renal impairment from birth. It does not progress in the first years of life if infections are prevented. It is suggested that males with this condition may constitute a major group at risk of developing chronic renal failure in later life.

Abstract
BACKGROUND Conventionally, vesicoureteric reflux (VUR) is assessed by fluoroscopic micturating cystourethrography (MCU) or direct or indirect radionuclide cystography (RNC). There is preliminary experience with contrast-enhanced sonography for the detection of VUR. OBJECTIVE To evaluate the usefulness of contrast-enhanced ultrasonography using galactose suspension as an echogenic contrast medium. MATERIALS AND METHODS In this study a galactose suspension was instilled into the bladder in 58 neonates, infants and children along with normal saline to detect the presence and the severity of VUR through the enhanced US signal. The results were compared with those of MCU and RNC. One ml/kg of echocontrast in the neonatal age group, and 0.5 ml/kg thereafter, were slowly instilled through a 4-F catheter after preliminary supine and prone urinary tract US. Indications for the investigation were antenatally diagnosed pyelectasis (21 cases) and pyelonephritis (37 cases). In 38 patients echocontrast cystosonography (ECS) was performed before, and in 20 patients after, MCU or RNC. RESULTS ECS detected 76 refluxing units in 50 patients. In eight patients, no VUR was shown, and none of these developed a urinary tract infection in 18 months of follow-up. In 43 patients, MCU or RNC detected 62 refluxing units, while in 15 no VUR was shown. Taking MCU as the gold standard and using the same grading scale, the sensitivity of ECS was 100 %. No side effects were observed. Several urinary tract abnormalities were detected by ECS. The male urethra was studied by ECS, both by retrograde infusion and during micturition. CONCLUSIONS ECS is a promising imaging technique for detecting and grading VUR without exposing patients to ionising radiation.

Abstract
Mutations of the renal-specific chloride channel (CLCN5) gene, which is located on chromosome Xp11.22, are associated with hypercalciuric nephrolithiasis (kidney stones) in the Northern European and Japanese populations. CLCN5 encodes a 746 amino acid channel (CLC-5) that has approximately 12 transmembrane domains, and heterologous expression of wild-type CLC-5 in Xenopus oocytes has yielded outwardly rectifying chloride currents that were markedly reduced or abolished by these mutations. In order to assess further the structural and functional relationships of this recently cloned chloride channel, additional CLCN5 mutations have been identified in five unrelated families with this disorder. Three of these mutations were missense (G57V, G512R and E527D), one was a nonsense (R648Stop) and one was an insertion (30:H insertion). In addition, two of the mutations (30:H insertion and E527D) were demonstrated to be de novo, and the G57V and E527D mutations were identified in families of Afro-American and Indian origin, respectively. The G57V and 30:H insertion mutations represent the first CLCN5 mutations to be identified in the N-terminus region, and the R648Stop mutation, which has been observed previously in an unrelated family, suggests that this codon may be particularly prone to mutations. Heterologous expression of the mutations resulted in a marked reduction or abolition of the chloride currents, thereby establishing their functional importance. These results help to elucidate further the structure-function relationships of this renal chloride channel.

Abstract
Micturating dysfunctions with urinary retention and with diurnal and nocturnal enuresis in children sometimes have a psychogenic genesis. They can appear during the period of development of complete control of micturition. A late recognition of this condition makes the prognosis worse, since high pressure and infections in the urinary tract can cause end-stage renal failure. Here we describe a dramatic case of a 3 year-old boy affected by a psychogenic urine and faecal retention with recurrent pyelonephritis, that was favourably treated for five years by an integrated approach involving clinicians, psychologist, educational and social operators and adoptive parents.

Abstract
PURPOSE Erythropoietin-dependent pure erythrocytosis (EDPE) is a rare disorder caused by idiopathic hypererythropoietinemia. We describe a 13-year-old girl who developed an EDPE-like erythrocytosis after removal of an adrenal pheochromocytoma. PATIENTS AND METHODS As occurs in EDPE, this post-pheochromocytoma erythrocytosis was associated with a high serum erythropoietin (s-Epo) level that maintained physiological regulation. RESULTS Phlebotomies produced a three- to sixfold increase of s-Epo, and a 6-week course of theophylline caused a decrease of both s-Epo and hemoglobin. CONCLUSIONS We hypothesize that the intense and prolonged pheochromocytoma-induced renal ischemia before surgery could be the cause of this unique case of erythrocytosis.

Abstract
A case of Henoch-Schönlein purpura (HSP) characterized by several unusual complications and exceedingly prolonged course is reported. A 6-year-old boy, hospitalized with a typical clinical picture of HSP, developed after a few days a severe gastrointestinal vasculitis leading to digestive hemorrhages and food intolerance. The treatment included continuous gastrointestinal infusion, parenteral nutrition, and corticosteroids during the exacerbations of symptoms. Intestinal ultrasonography showed diffuse submucous edema and widespread mural hematomas; hydrops of the gallbladder and edematous swelling of the pancreas were also detected. A gastro-duodenoscopy revealed diffuse and severe mucosal vasculitis with ulcers and petechial lesions. One week after admission the occurrence of weight gain, hyponatremia, and hypoprotidemia in the absence of proteinuria suggested a protein-losing enteropathy. The elevation of serum and urine amylases was consistent with pancreatic involvement. The course was characterized by recurrent exacerbations of gastrointestinal manifestations; symptoms subsided slowly to such a degree that oral feeding could be gradually restarted only seven weeks after admission. The use of high-frequency intestinal ultrasonography proved useful and sensitive in monitoring the evolution of intestinal involvement. During hospitalization the child complained of acute painful scrotal swelling. Ultrasonography showed scrotal hemorrhage and testicular swelling but no signs of testicular torsion, thus helping to avoid surgical exploration. In the recovery phase the child complained of colicky abdominal pain with vomiting. A plain abdominal roentgenogram showed bilateral staghorn pelvic urolithiasis. This finding was confirmed by an intravenous pyelography which also revealed a bilateral pyeloureteritis with edema of the ureteral wall and partial stenosis of the lumen.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Five children with tuberous sclerosis (TS), a polysystemic disease, had cardiac tumors detected by B-mode echocardiography. In a fetus, sonography performed at the eighth month showed the presence of a cardiac mass and of polycystic kidneys: the diagnosis of TS was confirmed postnatally because of the presence of calcified cerebral nodules. A newborn dichorial twin had paroxysmal tachycardia at ten days. B-mode echocardiography showed the presence of seven intracardiac tumors, and cerebral CT the presence of multifocal periventricular calcifications. An absence in a nine month old baby prompted an electrocardiogram that proved abnormal; a B-mode echocardiography showed large apical cardiac tumor; again cerebral CT showed periventricular calcified nodules. Two girls, 9 and 10 y.o. respectively, affected by TS, with normal electrocardiograms, both presented a small, asymptomatic, intracardiac mass demonstrated sonographically. In recent years, prenatal sonography and B-mode echocardiography in patients with TS demonstrated with increasing frequency the association of cardiac tumors (rhabdomyomas) with TS. Tumor detection often precedes the appearance of the cutaneous and neurological signs typical of the disease. This paper emphasizes the role of echocardiography in detecting cardiac tumors, as an early sign for the diagnosis of tuberous sclerosis, and to depict the natural history of cardiac rhabdomyoma with its variable clinical presentation and prognosis.

Abstract
Twenty-seven children [2 with chronic renal failure (CRF)] with reflux or obstructive nephropathy underwent intravenous urography with iopamidol 370, a nonionic contrast medium 1 (CM), osmolality 796 mosmol/kg, for renal growth evaluation. Mean iopamidol dosing was 1.69 ml/kg (range 1.22-2.42); the 2 children with CRF received 2 and 2.42 ml/kg respectively. One hour after infusion a significant decrease in haematocrit, haemoglobin, plasma sodium (Na+), chloride (Cl-), renin activity and aldosterone was observed, consistent with a possible plasma volume expansion due to the slightly hypertonic CM. At the same time there was a significant increase in fractional excretion of Na+, Cl- and potassium, probably due to the haemodynamic effects and tubular response to a substance acting as on osmotic diuretic. The -24 to +48 h monitoring of albuminuria, beta-2-microglobulin excretion, and in 4 children excretion of N-acetyl-beta-glucosaminidase and alanine-aminopeptidase did not show any relevant nephrotoxicity. No untoward effect of clinical relevance was observed.

Abstract
Transient hyperphosphatasemia of infancy is a biochemical syndrome characterized by a striking, transient increase in serum alkaline phosphatase in children without any evidence of bone or liver disease and of a familial occurrence. The abnormal isoenzyme pattern frequently observed in this syndrome may represent an excessively sialylated form of the liver isoenzyme, not normally removed from circulation. Here are described four new cases of this syndrome, followed biochemically and clinically until normalization of the serum abnormalities; a review of literature is also presented.

Abstract
A premature newborn developed left sciatic palsy and gluteal necrosis following umbilical artery catheterization. A six-year follow-up revealed an one-cm shortening of the left leg and foot, with an appreciable functional recovery. In connection with this rare thromboembolic complication of catheterization, we reviewed the Literature about the pathogenetic and clinical aspects of foot-drop and gluteal necrosis.

Abstract
The "quality" of poly(glycolic acid) as an absorbable suture material was investigated in comparison with catgut. Tissue reactions to poly(glycolic acid) and plain catgut were examined histomorphologically at different time intervals after implantation in rats, and compared. Four mechanical properties were also examined as relevant quality factors: elastic stiffness, tensile strength, toughness, and percent elongation at rupture of the suture material per se (unknotted). The variation of these properties in poly(glycolic acid) implants was followed since their insertion in the tissues. Histological behavior and mechanical properties appear to be more closely correlated in the case of poly(glycolic acid) than in the case of catgut, as a consequence of a greater regularity of tissue reaction towards the synthetic material. Both tissue reaction and tensile properties variation are independent of size in the case of the braided poly(glycolic acid) sutures examined. Elastic stiffness and tensile strength decrease steadily in time; toughness and ultimate elongation display an increase up to a maximum within one day since implantation, and then decrease.

Abstract
Tissue reactions to polyglycol acid and plain catgut threads were compared. The second part of the paper deals with changes in the mechanical properties of the polymer. Their reduction after insertion in tissues was proportionally equal for threads of different sizes. This finding is explicable histologically, since it can be shown that cell and humoral attack of the single filaments is homogenous throughout the entire cross-section of the thread.
