Abstract
OBJECTIVE Sub-trochanteric fractures are among the most challenging for trauma surgeons. The purpose of this study was to analyze our own experience about subtrochanteric fractures. We focused on functional and radiographic outcomes after intramedullary locked nail fixation with or without cerclage assist. PATIENTS AND METHODS A retrospective analysis on subtrochanteric fractures managed from January 2016 to April 2021 was conducted. Patients treated by closed reduction and intramedullary nail fixation were enrolled in Group A, while Group B included those patients who underwent wire-assisted intramedullary nail fixation. All patients performed clinical and radiological follow-up and complications were analyzed. The significance was established for a value of p < 0.05. RESULTS 80 patients were included in the present study. The mean age was 74.2 (+/-19.2) years. The mean surgical time was 84.7 (+/-24.6) and 254.7 (+/-80.2) minutes in Group A and Group B, respectively. The mean blood loss was 87.3 (+/-18.3) ml in Group A and 224.4 (+/-37.8) ml in Group B. Quality of reduction was mainly superior in Group B. The mean time of union was 4.2 (+/-1.4) months in Group A and 3.4 (+/-2.1) months in Group B. Statistical differences were observed in Visual Analogue Scale (VAS) and in the Short Form 12 (SF-12) after 6 and 12 months of follow-up with better results in Group B. The complication rate was 18.2% in Group A and 12.2% in Group B. CONCLUSIONS We recommend the use of wires when acceptable closed reduction cannot be obtained because its use may be useful for medial wall stability. For elderly patients, closed reduction may be more appropriate as the quality of life and functional recovery between the two methods is almost overlapped.

Abstract
BACKGROUND Short-stem Hip Arthroplasty (SHA) are increasingly implanted in recent years thanks to their potential advantage in preserving metaphyseal bone-stock. Among them, the NANOS® short-stem implant demonstrated satisfactory results to short and mid-term. The purpose of this retrospective study was to evaluate the clinical and radiographic outcome of the Nanos® short stem at a minimum follow-up of 10 years. METHODS Sixty-seven patients aged 53 ± 20 years were enlisted in the study, for a total of 72 hips. Primary outcomes were survivorship of the implant and clinical outcome measured using the Hip disability and Osteoarthritis Outcome scores (HOOS) and the Short Form Survey (SF12) questionnaire. The secondary outcome was a radiological evaluation calculating the inclination and the anteversion angle of the acetabular cup for each implant and investigating osteolysis, heterotopic ossifications and stem position. RESULTS We observed a 95.5% stem survivorship. The complication rate was 7.6% and three implants underwent revision because of an aseptic loosening, an infection and a periprosthetic fracture due to trauma. Among 58 patients (63 hips) evaluated in an outpatient visit 10-16 years after surgery, improvement in clinically relevant scores comparing with baseline was observed: HOOS score increased after surgery in all its subcategories (from 32.25 ± 14.07% up to 91.91 ± 9.13%) as well as SF12 which increased by more than 18 percentage points. On clinical assessment, the range of motion (ROM) was restored at follow-up, 1 patient (1.7%) showed a squeaking hip and 2 (3.4%) reported leg-length discrepancy. Neutral stem positioning was achieved in 58 hips and heterotopic ossifications occurred in 10 hips (16%). CONCLUSIONS The current study reports good clinical and radiological outcomes following NANOS® short-stem hip implant at minimum 10 years-follow-up. Since the high rate of stem survivorship, the low complication rate demonstrated and the overall patient satisfaction, our results suggest NANOS® neck-preserving prostheses should be considered as a valid alternative to standard implants.

Abstract
BACKGROUND Elevated fasting plasma glucose has been associated with increased risk for development of type 2 diabetes (T2D). The balance between glucokinase (GCK) and glucose-6-phosphate catalytic subunit 2 (G6PC2) activity are involved in glucose homeostasis through glycolytic flux, and subsequent insulin secretion. AIM In this study, we evaluated the association between the genetic variability of G6PC2 and GCK genes and T2D-related quantitative traits. METHODS In 794 drug-naïve, GADA-negative, newly diagnosed T2D patients (VNDS; NTC01526720) we performed: genotyping of 6 independent tag-SNPs within GCK gene and 5 tag-SNPs within G6PC2 gene; euglycaemic insulin clamp to assess insulin sensitivity; OGTT to estimate beta-cell function (derivative and proportional control; DC, PC) by mathematical modeling. Genetic association analysis has been conducted using Plink software. RESULTS Two SNPs within GCK gene (rs882019 and rs1303722) were associated to DC in opposite way (both p < 0.004). Two G6PC2 variants (rs13387347 and rs560887) were associated to both parameters of insulin secretion (DC and PC) and to fasting C-peptide levels (all p < 0.038). Moreover, subjects carrying the A allele of rs560887 showed higher values of 2h-plasma glucose (2hPG) (p = 0.033). Haplotype analysis revealed that GCK (AACAAA) haplotype was associated to decreased fasting C-peptide levels, whereas, the most frequent haplotype of G6PC2 (GGAAG) was associated with higher fasting C-peptide levels (p = 0.001), higher PC (β = 6.87, p = 0.022) and the lower 2hPG (p = 0.012). CONCLUSION Our findings confirmed the role of GCK and G6PC2 in regulating the pulsatility in insulin secretion thereby influencing insulin-signaling and leading to a gradual modulation in glucose levels in Italian patients with newly diagnosed T2D.

Abstract
BACKGROUND Intra-articular hip injections for osteoarthritis represent a useful instrument to reduce pain and disability in the common clinical practice. Several medications can be injected locally with different level of evidence-based efficacy. OBJECTIVE The objective of this systematic review is to investigate the effectiveness of intra-articular injections of different medications or substances for the pain treatment and the management of disability in subjects affected by hip osteoarthritis. METHODS Two reviewers selected independently randomised controlled trials published in the last 10 years, using PubMed and Scopus databases. The risk of bias was evaluated with Cochrane library assessment tool. RESULTS 12 randomised controlled trials have been selected. We found 8 papers comparing hyaluronic acid with platelet rich plasma, with corticosteroids and with saline solution; 1 paper compares two types of hyaluronic acid with different molecular weights; 3 papers study the effects of corticosteroids alone or compared to ketorolac or saline solution. CONCLUSIONS The studies reviewed were heterogeneous regarding sample size, level of osteoarthritis, evaluated with Kellegren-Lawrence score, medications used and follow up timings. However, we have observed that intra-articular injections of platelet-rich plasma seem to decrease pain at short term and disability at long term, in patients affected by hip osteoarthritis better than hyaluronic acid. The association of hyaluronic acid and corticosteroids could give better results compared to hyaluronic acid alone, while the use of intra-articular ketorolac and saline solution requires more studies.

Abstract
BACKGROUND Several studies have evaluated the survivorship and clinical outcomes of proximal femoral replacement (PFR) in complex primary and revision total hip arthroplasty with severe proximal femoral bone loss; however, there remains no consensus on the overall performance of this implant. We therefore performed a systematic review of the literature in order to examine survivorship and complication rates of PFR usage. METHODS A systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed. A comprehensive search of PubMed, MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews was conducted for English articles using various combinations of keywords. RESULTS In all, 18 articles met the inclusion criteria. A total of 578 PFR were implanted. The all-cause reoperation-free survivorship was 76.6%. The overall complication rate was 27.2%. Dislocation was the most common complication observed and the most frequent reason for reoperation with an incidence of 12.8 and 7.6%, respectively. Infection after PFR had an incidence of 7.6% and a reoperation rate of 6.4%. The reoperation rate for aseptic loosening of the implant was 5.9%. Overall, patients had improved outcomes as documented by postoperative hip scores. CONCLUSION PFR usage have a relatively high complication rate, however, it remains an efficacious treatment option in elderly patients with osteoporotic bone affected by severe proximal femoral bone loss. Modular designs have shown reduced dislocations rate and higher survivorship free from dislocation. However, PFR should only be used as salvage procedure when no other reconstruction options are available.

Abstract
Implant-associated infections remain one of the main problems in trauma surgery, particularly for treatment of open tibial fractures. The role of systemic antibiotic prophylaxis is now established and accepted, but recent literature also seems to emphasize the importance of local antibiotic prophylaxis. Antibiotic coated nails play a crucial role, allowing at the same time the prevention of infections and favoring the stabilization of fractures. These devices appear to be a clinically effective and safe solution. The purpose of the study was to investigate the role of antibiotic coated nails in the treatment of tibia fractures. A literature review was performed on MEDLINE through PubMed to identify scientific publications relevant to the use of antibiotic coated nails in tibial fractures. Primary outcomes were infection rate and bone union rate. This review present numerous limits due primarily to the small number and different nature of studies published; the heterogeneity of the devices used.

Abstract
INTRODUCTION Humerus fractures are frequent, accounting for about 3-4% of all fractures in adults. Treatment for fractures of the diaphyseal and proximal meta-epiphyseal regions remains controversial: there is no unanimity in the scientific community about the superiority of surgical treatment over non-surgical treatment and which is the best between possible surgical treatments. Among the choices for surgical treatment the most commonly used implants are the locking-compression plate and the intramedullary nailing. The purpose of this study was to perform a clinical and radiographic follow-up in patients who underwent surgical procedures for reduction and osteosynthesis of proximal or diaphyseal humeral fractures by means of anterograde intramedullary nailing with a straight-shaped nail. PATIENTS AND METHODS A clinical and radiographic follow-up was performed in 56 patients who underwent surgical procedures for reduction and osteosynthesis of proximal or diaphyseal humeral fractures by means of antegrade intramedullary nailing using Synthes MultiLoc® system. Clinical data were collected using subjective quality of life assessment forms (SF12-v2), quality of life related to specific disabilities assessment forms (Quick-DASH, ASES score, WORC) and objective functional assessment forms (Constant-Murley score). The radiographic Follow-Up was performed at 30, 90 and 180 days from the date of the surgery. RESULTS Almost all patients were able to return to a satisfactory quality of life, comparable with the one before the traumatic episode. The functional results were assessed as excellent or good with almost complete recovery of the range of motion and moderate recovery of strength. The residual pain encountered was moderate or zero. The average QuickDASH score was 17.7 ± 4.3 (range 9.1 - 27.3). The average ASES score was 73.8 ± 8.1 (range 58.3 - 88.3). The average WORC score was 543.3 ± 100 [74% ± 4.8%] (range 310 - 740). The mean Constant-Murley score was 69.6 ± 4.6 (range 61 - 84). All patients had a fair or good consolidation of the fracture on radiographic examinations. The calculated RUST score was 4.2 ± 0.4 (range 4-5) 30 days after surgery, 6.1 ± 0.9 (range 4- 8) 90 days after surgery and 9.8 ± 1.5 (range 7-12) to 180 days after surgery. No major complications were found. CONCLUSIONS Treatment of the diaphyseal and proximal meta-epiphyseal humeral fractures with antegrade intramedullary nail provides excellent subjective and objective clinical results and good radiographic results. However, clinical studies with larger number of patients and longer follow-up are necessary.

Abstract
Postoperative drainage after total knee arthroplasty (TKA) is an established routine procedure for orthopedic surgeries, and is considered a useful practice in postoperative, but the use of drainage is controversial. Our study aims to clarify this aspect of knee prosthetic surgery. A systematic review of the literature was performed in the electronic databases to investigate the risks and the benefits of wound drainage in total knee arthroplasty: 30 articles were included in our review for eligibility. After the analysis of the literature performed, we found no significant advantages related with the use of wound drain following total knee replacement (TKR) in terms of pain, transfusion rate, blood loss, swelling, postoperative range of motion, wound complications, deep infection and hospital stay, while no drainage means a significant cost saving compared to drainage use. Thus, the use of drainage after TKA cannot be justified on the basis of the results of this study.

Abstract
Humeral fractures have an incidence of 3-5% and a bimodal age distribution. They may occur in young patients after highenergy traumas or in elderly osteoporotic patients after low-energy injuries. In nondisplaced fractures or in elderly patients, humeral fractures are treated by conservative methods. Open reduction and internal fixation (ORIF) should be the treatment of choice in case of multi-fragmentary fractures associated with radial nerve palsy or not. ORIF is usually regarded as the gold standard treatment, but, depending on the different types of fracture, the surgical approach can change. In this review, we compare results and complication rates between lateral and posterior surgical approaches in the management of extraarticular distal humeral shaft fractures. An internet-based literature research was performed on Pubmed, Google Scholars and Cochrane Library. 265 patients were enrolled: 148 were treated by lateral or antero-lateral approach, while 117 by posterior or postero-lateral approach. The literature shows that no differences between the posterior and lateral approach exist. Certainly, the posterior approach offers undoubted advantages in terms of exposure of the fracture and visualization of the radial nerve. In our opinion, the posterior approach may also allow better management of complex and multi-fragmentary fractures.

Abstract
Elbow stiffness is defined as any loss of movement that is greater than 30° in extension and less than 120° in flexion. Causes of elbow stiffness can be classified as traumatic or atraumatic and as congenital or acquired. Any alteration affecting the stability elements of the elbow can lead to a reduction in the arc of movement. The classification is based on the specific structures involved (Kay’s classification), anatomical location (Morrey’s classification), or on the degree of severity of rigidity (Vidal’s classification). Diagnosis is the result of a combination of medical history, physical examination (evaluating both active and passive movements), and imaging. The loss of soft tissue elasticity could be the result of bleeding, edema, granulation tissue formation, and fibrosis. Preventive measures include immobilization in extension, use of post-surgical drain, elastic compression bandage and continuous passive motion. Conservative treatment is used when elbow stiffness has been present for less than six months and consists of the use of serial casts, static or dynamic splints, CPM, physical therapy, manipulations and functional re-education. If conservative treatment fails or is not indicated, surgery is performed. Extrinsic rigidity cases are usually managed with an open or arthroscopic release, while those that are due to intrinsic causes can be managed with arthroplasties. The elbow is a joint that is particularly prone to developing stiffness due to its anatomical and biomechanical complexity, therefore the treatment of this pathology represents a challenge for the physiotherapist and the surgeon alike.

Abstract
Regulation of alternative splicing events is an essential step required for the expression of functional cytoskeleton and sarcomere proteins in cardiomyocytes. About 3% of idiopathic dilated cardiomyopathy cases present mutations in the RNA binding protein RBM20, a tissue specific regulator of alternative splicing. Transcripts expressed preferentially in skeletal and cardiac muscle, including TTN, CAMK2D, LDB3, LMO7, PDLIM3, RTN4, and RYR2, are RBM20-dependent splice variants. In the present study, we investigated the RBM20 involvement in post-transcriptional regulation of splicing variants expressed by Formin homology 2 domain containing 3 (FHOD3) gene. FHOD3 is a sarcomeric protein highly expressed in the cardiac tissue and required for the assembly of the contractile apparatus. Recently, FHOD3 mutations have been found associated with heart diseases. We identified novel FHOD3 splicing variants differentially expressed in human tissues and provided evidences that FHOD3 transcripts are specific RBM20 and PTBP1 targets. Furthermore, we demonstrated that the expression of RBM20 and PTBP1 promoted the alternative shift, from inclusion to exclusion, of selected FHOD3 exons. These results indicate that RBM20 and PTBP1 play a role in the actin filament functional organization mediated by FHOD3 isoforms and suggest their possible involvement in heart diseases.

Abstract
Background: Nasal polyposis (NP) is an inflammatory disease of the upper nasal airways frequently present in CF patients. Interferon-Related Developmental Regulator 1 (IFRD1) gene was reported as a possible modifier of CF lung disease severity. Three IFRD1 SNPs were analyzed to investigate a possible effect on the development of NP in CF patients. Methods and patients: The DNA of 143 patients with CF (40 with and 103 without NP) was purified from peripheral blood samples. IFRD1 SNPs (rs7817, rs3807213, rs6968084) were genotyped by restriction enzyme analysis. Results: The T allele of the common polymorphisms rs7817 and the rs7817-rs3807213 haplotype were associated with NP (p = 0.002 and 0.004, respectively). Conclusions: These results showed the association of the IFRD1-rs7817 polymorphism with NP in CF patients.

Abstract
We investigated cross-sectionally whether the type 2 diabetes (T2DM) risk alleles of rs1801282 (PPARG2) and rs4607103 (ADAMTS9) were associated with T2DM and/or insulin sensitivity (IS) and beta cell function (βF) in Italians without and with newly diagnosed T2DM. In 676 nondiabetic subjects (336 NGR and 340 IGR) from the GENFIEV study and in 597 patients from the Verona Newly Diagnosed Type 2 Diabetes Study (VNDS), we (1) genotyped rs1801282 and rs4607103, (2) assessed βF by C-peptide/glucose modeling after OGTT, and (3) assessed IS by HOMA-IR in both studies and by euglycemic insulin clamp in VNDS only. Logistic, linear, and two-stage least squares regression analyses were used to test (a) genetic associations with T2DM and with pathophysiological phenotypes, (b) causal relationships of the latter ones with T2DM by a Mendelian randomization design. Both SNPs were associated with T2DM. The rs4607103 risk allele was associated to impaired βF (p < 0.01) in the GENFIEV study and in both cohorts combined. The rs1801282 genotype was associated with IS both in the GENFIEV study (p < 0.03) and in the VNDS (p < 0.03), whereas rs4607103 did so in the VNDS only (p = 0.01). In a Mendelian randomization design, both HOMA-IR (instrumental variables: rs1801282, rs4607103) and βF (instrumental variable: rs4607103) were related to T2DM (p < 0.03-0.01 and p < 0.03, respectively). PPARG2 and ADAMTS9 variants are both associated with T2DM and with insulin resistance, whereas only ADAMTS9 may be related to βF. Thus, at least in Italians, they may be considered bona fide "insulin resistance genes".

Abstract
Total Hip Arthroplasty (THA) is one of the most common orthopedic operations in the world. The number of THA is expected to grow and with it the number of associated complications. Although improved surgical technique and the development of more scrupulous asepsis has decreased the incidence of periprosthetic joint infection (PJI), it remains one of the most feared complications of joint arthroplasty. The purpose of this study is to present the use of antibiotic-loaded collagen sponges (Collatamp EG) in the prophylaxis and treatment of PJI. For this scope a case report is described. The advantages offered by the antibiotic loaded sponges in terms of high and sustained concentration of antibiotic at the site of infection, diffused by the fully reabsorbable carrier, showed to be a an important adjuvant therapy in the treatment of PJI. Low systemic concentration of the drug and a wide versatility in surgical application are other advantages of this dispositive.

Abstract
BACKGROUND Hepatitis C virus (HCV) is a major cause of chronic liver disease, cirrhosis and hepatocellular carcinoma and the identification of the predictors of response to antiviral therapy is an important clinical issue. AIM To determine the independent contribution of factors including IL28B polymorphisms, IFN-gamma inducible protein-10 (IP-10) levels and the homeostasis model assessment of insulin resistance (HOMA-IR) score in predicting response to therapy in chronic hepatitis C (CHC). METHODS Multivariate analysis of factors predicting rapid (RVR) and sustained (SVR) virological response in 280 consecutive, treatment-naive CHC patients treated with peginterferon alpha and ribavirin in a prospective multicentre study. RESULTS Independent predictors of RVR were HCV RNA <400 000 IU/mL (OR 11.37; 95% CI 3.03-42.6), rs12980275 AA (OR 7.09; 1.97-25.56) and IP-10 (OR 0.04; 0.003-0.56) in HCV genotype 1 patients and lower baseline γ-glutamyl-transferase levels (OR=0.02; 0.0009-0.31) in HCV genotype 3 patients. Independent predictors of SVR were rs12980275 AA (OR 9.68; 3.44-27.18), age <40 years (OR=4.79; 1.50-15.34) and HCV RNA <400 000 IU/mL (OR 2.74; 1.03-7.27) in HCV genotype 1 patients and rs12980275 AA (OR=6.26; 1.98-19.74) and age <40 years (OR 5.37; 1.54-18.75) in the 88 HCV genotype 1 patients without a RVR. RVR was by itself predictive of SVR in HCV genotype 1 patients (OR 33.0; 4.06-268.32) and the only independent predictor of SVR in HCV genotype 2 (OR 9.0, 1.72-46.99) or genotype 3 patients (OR 7.8, 1.43-42.67). CONCLUSIONS In HCV genotype 1 patients, IL28B polymorphisms, HCV RNA load and IP-10 independently predict RVR. The combination of IL28B polymorphisms, HCV RNA level and age may yield more accurate pre-treatment prediction of SVR. HOMA-IR score is not associated with viral response.

Abstract
CONTEXT Intronic variants of TCF7L2 are confirmed genetic risk factors for type 2 diabetes and are associated to alterations in beta cell function in nondiabetic individuals. OBJECTIVE The objective of the study was to test whether TCF7L2 variability may affect β-cell function also in patients with type 2 diabetes. DESIGN This was a cross-sectional association study. SETTING The study was conducted at a university hospital referral center for diabetes. PATIENTS Patients included 464 (315 males and 149 females) glutamic acid decarboxylase-negative patients [age: median 59 yr (interquartile range: 52-65); body mass index: 29.3 kg/m(2) (26.5-32.9); fasting plasma glucose: 7.0 mmol/liter (6.1-8.0)] with newly diagnosed type 2 diabetes. INTERVENTION(S) Interventions included frequently sampled oral glucose tolerance test and euglycemic insulin clamp. MAIN OUTCOME MEASURE(S) β-Cell function (derivative control and proportional control); insulin sensitivity; genotypes of the following TCF7L2 single-nucleotide polymorphisms: rs7901695, rs7903146, rs11196205, and rs12255372. RESULTS Both rs7901695 and rs7903146 diabetes risk alleles were associated with reduced proportional control of β-cell function (P = 0.019 and P = 0.022, respectively). Two low-frequency haplotypes were associated with extreme (best and worst) phenotypes of β-cell function (P < 0.01). No associations between TCF7L2 genotypes and insulin sensitivity were detected. CONCLUSIONS TCF7L2 diabetes risk variants, either as single-nucleotide polymorphisms or as haplotypes, detrimentally influence β-cell function and might play a role in determining the metabolic phenotype of patients with newly diagnosed type 2 diabetes.

Abstract
OBJECTIVES An inflammatory process following stroke in human brains and systemic inflammatory responses after stroke in humans have been reported by numerous investigators. The aim of the study was to investigate if genes involved in the cyclooxygenase 2 (COX-2) pathway are upregulated at peripheral level in patients after transient ischaemic attack (TIA) and stroke. DESIGN OF STUDY Blood samples were obtained from two groups of patients undergoing carotid endarterectomy. The first group included 25 patients who presented TIA or ischaemic stroke. The second group included 35 patients who had an asymptomatic internal carotid artery stenosis. Total RNA was isolated and the expression of Toll-like Receptor 4 (TLR4), COX-2, membrane-associated Prostaglandin E synthase (mPGES-1), Prostaglandin E₂ receptors (EP3 and EP4) was analysed by real time RT-PCR. RESULTS Expression of COX-2 and TLR4 were significantly increased in symptomatic patients (p < 0.001). Correlation analysis showed that TLR4 expression significantly correlated with COX-2 expression (R = 0.65; p < 0.01) in ischaemic stroke patients. This correlation was not observed in TIA and asymptomatic patients. CONCLUSIONS Our results suggest that the peripheral mechanism of inflammatory injury after stroke may be mediated by TLR4 through a COX-2-dependent pathway.

Abstract
BACKGROUND Several genome scans have reported linkage of markers on chromosome 7p with asthma and related phenotypes in different populations. A fine mapping in Finnish and French-Canadian populations has associated the GPR154 gene (also known as G-protein-coupled receptor for asthma susceptibility, GPRA) with elevated IgE or asthma. OBJECTIVE To confirm chromosome 7p linkage and candidate gene association in Italian families with atopic asthma. METHODS In a two-phase approach, we first performed a linkage analysis of chromosome 7, and then a family-based association study on the GPR154 gene for allergic asthma phenotypes in the Italian population. RESULTS The screening of 117 families with 19 microsatellite markers showed potential linkage for elevated IgE (P<0.002 at 22 cM from p-ter), asthma (P<0.005 at 44 cM), or atopy (P<0.005 at 54 cM). In the second phase of the present study, candidate gene GPR154, which is located in the phase one-linked region, was investigated in 211 families with seven single nucleotide polymorphisms (SNPs) that tag most haplotype variability, by the pedigree disequilibrium test. Elevated IgE levels were associated with two GPR154 gene SNPs (SNP 546333, P=0.0046; rs740 347, P=0.006), and with haplotypes in the global test (P=0.013). Haplotype analysis performed in nuclear families having at least 1 asthmatic parent showed a significant association with asthma (P=0.0173), atopy (P=0.0058), SPT (P=0.0025), and bronchial hyper reactivity (P=0.0163). CONCLUSION These results support a susceptibility locus for asthma and related phenotypes on chromosome 7, and are in agreement with recent reports suggesting that a common susceptibility factor for atopic manifestations in asthma is likely conferred by the locus containing the GPR154 gene.

Abstract
BACKGROUND Overexpression of cyclooxygenase-2 (COX-2), resulting in excessive prostaglandin production, has been observed in human epidermal keratinocytes after ultraviolet B injury, in squamous cell skin carcinoma (SCC), in actinic keratoses, and in the early stages of carcinogenesis in a wide variety of tissues. The dysregulation of COX-2 expression can in part be due to functional changes affecting regulatory elements in the promoter or 3' untranslated region (UTR) of the gene. Two common polymorphisms (-765G-->C, and -1195A-->G) in the promoter region of the COX-2 gene (now PTGS2), and one common polymorphism in the 3' UTR (8473T-->C) have been described, and reported as associated with various malignancies. OBJECTIVES To determine if common known polymorphisms in the regulatory region of the COX-2 gene (PTGS2) can be associated with nonmelanoma skin cancer (NMSC) predisposition after organ transplantation, to evaluate if cancer risks are associated with specific COX-2 gene (PTGS2) haplotypes containing these polymorphisms, and to identify possible new genetic polymorphisms in the proximal 5' or 3' regulatory regions of the gene associated with disease. METHODS The frequency of the three polymorphisms was determined in 240 Northern Italian transplant recipient patients (107 cases and 133 controls) with polymerase chain reaction-restriction fragment length polymorphism analysis. The proximal 5' and 3' regulatory regions of the gene were screened by heteroduplex analysis. RESULTS Stratification by age at transplant and type of tumours [SCC or basal cell carcinoma (BCC)] demonstrated that allele -765C represented a protective factor in BCC cases undergoing transplantation before 50 years of age (CC + CG vs. GG, Fisher exact test P = 0.003). One rare polymorphism, -62C-->G, was detected in the 5' flanking region. The allele frequency of -62G was 0.019, and no difference in genotype between cases and controls was observed. No other variants were found, suggesting that sequence variations in these regions are not likely to contribute to NMSC risk in this population. Haplotype analysis showed that the haplotype containing all major alleles represents a protective factor in patients with SCC undergoing transplantation after 50 years of age [P = 0.009; OR = 0.37 (0.18-0.79)] and that variant -1195A-->G may represent a risk factor in this subgroup of patients [P = 0.01; OR = 4.77 (1.47-16.41)]. Haplotype analysis in patients with BCC revealed that variant -765C might be a protective factor in patients undergoing transplantation before 50 years of age. Variant 8473T-->C, located in the 3' UTR region of the gene, showed no association with NMSC risk after transplantation. CONCLUSIONS COX-2 common variants -765G-->C and -1195A-->G appear to be associated with risk of NMSC, although in different ways in the SCC and BCC subgroups, indicating that environmental and genetic risk factors may play different roles in the outcome leading to these two phenotypes.

Abstract
Cyclooxygenase-2 (COX-2) is extensively expressed in multiple sclerosis lesions suggesting that regulatory variants of the COX-2 gene could be implicated in multiple sclerosis (MS). Screening of the proximal 5' regulatory region and genotyping of -765G>C and -62C>G showed that polymorphisms in this COX-2 region are unlikely to be involved in MS susceptibility.

Abstract
AIM Study of frequency and position of accessory infraorbital foramen in a large craniological sample. METHODS A sample of 1 064 skulls from the craniological collection of the Department of Anatomy, Pharmacology and Forensic Medicine of the University of Turin (Italy) was investigated. RESULTS Accessory infraorbital foramen was found in 4.7% of the skulls (5.4% in male and 4.26% in female skulls) with a higher frequency on the left side, both in male and in female skulls. CONCLUSION These results increase our knowledge of the interindividual anatomic variability of the infraorbital region and can be of help for the maxillo-facial surgeon, especially in trunk block of the infraorbital nerve.

Abstract
The literature contains conflicting reports on the association of common variants of the interleukin (IL)-4 receptor alpha (IL4RA) gene with atopic asthma. The purpose of the present study was to investigate the linkage and association of several gene polymorphisms with atopic asthma in a large series of well-characterized individuals. Analysis of five polymorphisms (I50V, E375A, C406R, S478P and Q551R) of the IL4RA gene was performed in 823 individuals from 182 families with atopic asthmatic children from north-east Italy. The subjects were tested for clinical asthma, total serum IgE level, skin prick test positivity to common aeroallergens, and bronchial hyperresponsiveness to methacholine. The frequency of the polymorphisms was similar to that reported for other populations. The 375, 406, 478 and 551 polymorphisms were in linkage disequilibrium, as previously reported. No linkage or transmission disequilibrium was observed in the families between any mutation and any of the phenotypes investigated. No multipoint haplotype was associated with any phenotype. In conclusion, the IL4RA gene does not seem to play an important role in genetic predisposition to atopic asthma in the population tested.

Abstract
Osteoporosis is a disease characterized by low bone mineral density (BMD) and up to 80% of its variance is under genetic control. Although osteoporosis is more frequent in women, one-third of hip fractures also occur in men. Much information on genetic factors and bone density has been obtained in women, but only a few studies have been performed in osteoporotic men. We have evaluated the relationship between polymorphisms for several candidate genes such as vitamin D receptor (VDR), collagen type Ia1 (COLIA1), and calcitonin receptor (CTR) in a sample of unrelated Italian men (n = 253, mean age 58.41 +/- 15.64 SD). We found no significant differences in BMD when subjects were stratified for their VDR (BsmI and FokI) and COLIA1 genotypes. BMD both at the lumbar spine and at the femoral neck were associated with polymorphism of CTR gene. The CC genotype of CTR gene had the lowest BMD value (P <0.05 and P <0.01 at the spine and hip, respectively) and its prevalence was significantly over-represented in the subgroup of men with prior hip or vertebral fracture as compared with controls (P = 0.004% c2 = 11.10). The men with the CC genotype also showed significantly lower body mass index (BMI), serum sex hormone binding globulin (SHBG), estradiol, total alkaline phosphatase-(total AP) and bone alkaline phosphatase (bone AP) levels and significantly higher free androgen index (FAI). In conclusion, the polymorphism of CTR gene but not VDR and COLIA1 is associated with osteoporosis incidence and the levels of alkaline phosphatase and estradiol. The lower BMD in CC genotype is apparently associated in males with depressed bone formation and lower estradiol levels.

Abstract
BACKGROUND Allergic asthma is a multifactorial disease for which there is a widely assessed, although poorly understood, genetic involvement. Genome-wide screens reported evidence for linkage of allergic asthma-related phenotypes to several chromosomal locations. Markers on chromosome 19 have been linked to allergic asthma phenotypes in different populations in independent studies. OBJECTIVE The aim of this study was to perform a genetic linkage analysis on chromosome 19 to search for DNA markers linked to phenotypes related to allergic asthma. METHODS Using non-parametric multipoint linkage analysis on a total of 22 random DNA markers in 2 stages, a sample of 111 families (542 subjects) from north-eastern Italy, recruited through an asthmatic allergic proband, was investigated. Phenotypes examined were: clinical asthma, total serum elevated IgE, skin prick test positivity, bronchial hyper-responsiveness, and atopy defined as skin prick test positivity and/or elevated IgE. Simulation studies were performed to confirm the significance of the results. RESULTS A novel linkage of atopy and skin prick test positivity to marker D19S601 (19q13.3) was found. Modest evidence for linkage of atopy, skin prick test positivity, and IgE was also found to marker D19S591 (19p13.3). Simulation analysis for atopy gave an NPL-Z > 3.326 in 2 replicates out of 1000 (P = 0.002) for D19S601, and an NPL-Z > 2.56 in 16 replicates out of 1000 (P = 0.016) for D19S591. CONCLUSIONS On chromosome 19, suggestive linkage of atopy and skin prick test positivity with marker D19S601 (19q13.3) and modest evidence of linkage of marker D19S591 (19p13.3) to the atopic phenotypes investigated were found. These results suggest that these regions may contain susceptibility loci associated to atopic phenotypes.

Abstract
BACKGROUND Genome and chromosome screens reported DNA markers on chromosome 14 linked to allergic asthma or intermediate phenotypes in several populations. OBJECTIVE We sought to perform a linkage study on chromosome 14 and a further association study on candidate genes mapped in the region found to be linked to allergic asthma or intermediate phenotypes. METHODS The study consisted of a sample of 189 families (847 genotyped individuals) from a restricted geographic area in northeastern Italy. The subjects were characterized for the following phenotypes: allergic asthma, total serum IgE levels, skin prick test responses, and bronchial hyperresponsiveness (BHR) to methacholine. Genotyping was done with 14 DNA markers and 4 polymorphisms in the genes encoding alpha(1)-anti-trypsin and alpha(1)-antichymotrypsin (ACT). RESULTS Multipoint analysis indicated a potential linkage of BHR with marker D14S617 (nonparametric linkage z score = 2.32, P =.01). Transmission disequilibrium of Thr -15Ala in the gene encoding ACT was observed with all the phenotypes investigated: allergic asthma, BHR, total IgE levels, or skin prick test responses (P =.041,.02,.0053, or.026, respectively). CONCLUSION Chromosome 14 screening and transmission disequilibrium testing on the gene encoding ACT suggest that it or a closely located gene may be involved in susceptibility to allergic asthma in the Italian population.

Abstract
The variability of bone mass and bone strength is in part genetically determined. The pathophysiology of the disease is complex and its heritability is almost certainly polygenic. In a large group of women from north eastern Italy, homogeneous for calcium intake and other risk factors for osteoporosis, we investigated three different genetic polymorphic markers that have been associated with bone mineral density (BMD). The study includes 663 postmenopausal (aged 48-85 years) and 52 perimenopausal (aged 47-53 years) women. Lumbar spine and hip BMD were measured by dual energy X-ray absorptiometry (DXA). After DNA extraction, the restriction enzymes utilized were MscI for the SP1 site of the collagen type I regulatory region (COLIA1), AluI for the calcitonin receptor (CTR) gene, and BsmI for the Vitamin D receptor (VDR) gene. COLIA1 genotype was significantly associated with age-adjusted hip BMD, with the highest values in the SS group and the lowest in the ss group (p < 0.05). The COLIA1 effect was not visible until the sixth decade of life, but it increased thereafter with aging, becoming statistically significant also at the lumbar spine in subjects aged >70 years. CTR genotype was also significantly related to bone mass in the CC group, with the lowest age and weight-adjusted BMD values at the spine (p < 0.05). The CTR genotype effect was greater in the younger subset of women. This suggests that the CTR genotype might influence the process of acquiring peak bone mass rather than the process of bone loss along aging. No trend association was found between BMD values and VDR genotype. These findings suggest an association between the COLIA1 gene polymorphism more with the age-related rate of bone loss than with peak bone mass, which apparently is somewhat affected by CTR gene polymorphism.

Abstract
We investigated 116 Italian atopic families (560 individuals) for linkage with 13 DNA markers on chromosome 12. All the subjects were phenotyped for asthma, total serum IgE, bronchial hyperresponsiveness, skin-prick positivity to common aeroallergens, and atopy. A relative location map of the markers was prepared from Centre d'Etude du Polymorphisme Humain families. Affected sib pair multipoint linkage methods were used to perform the statistical analyses. We report suggestive linkage for asthma with markers on chromosome 12. The region of interest centers around marker D12S390 (maximum logarithm of odds [mlod] = 2.81; p = 0.003). These results provide additional support that asthma susceptibility factors are located on chromosome 12q.

Abstract
BACKGROUND Tumor necrosis factor (TNF) is a potent proinflammatory cytokine with increased levels in the sputum of COPD subjects. Two biallelic TNF gene complex polymorphisms have been described: LtalphaNcoI, in the first intron of the lymphotoxin alpha (previously referred to as TNF-beta) gene, and TNF-308, in the promoter region of the TNF-alpha gene. Higher levels of TNF production are associated with allele 1 of LtalphaNcoI (LtalphaNcoI*1) and with allele 2 of TNF-308 (TNF-308*2). STUDY OBJECTIVES To study the frequencies of the two TNF gene complex polymorphisms in patients with COPD and bronchiectasis. DESIGN Association study. SUBJECTS AND METHODS We studied the frequencies of these polymorphisms in 66 subjects with COPD and in 23 subjects with disseminated bronchiectasis and compared them to the frequencies in 98 healthy control subjects and 45 subjects with nonobstructive pulmonary disease. Genomic DNA samples were extracted, and TNF-alpha and LtalphaNcoI polymorphisms were detected after polymerase chain reaction by restriction digestion. RESULTS We found the following frequencies: the TNF-308*2 allele was detected in 11% of COPD individuals, 15% of bronchiectasis patients, 10% of healthy control subjects, and 18% of subjects with nonobstructive pulmonary disease. The LtalphaNcoI*1 allele was detected in 28% of COPD individuals, 30% of bronchiectasis patients, 29% of healthy control subjects, and 29% of subjects with nonobstructive pulmonary disease. We found evidence of linkage disequilibrium between the two loci (Delta = 0.068). CONCLUSIONS We conclude that the TNF gene complex, at least in Caucasoid individuals and for the considered polymorphisms, does not seem to play a major role as genetic risk factor in COPD and bronchiectasis.

Abstract
To identify genetic factors for susceptibility to atopy and asthma in childhood, 1,083 subjects were identified, mainly from the Veneto region and Bolzano province in North-east Italy, of whom 817 were from 172 families with at least two affected people, 189 were sporadic cases, and 77 unrelated controls. All the subjects were characterized for clinical asthma (asthma), total serum IgE (IgE), skin prick test (SPT) reactivity to common aeroallergens and bronchial hyperresponsiveness (BHR) to methacoline test. Atopy was defined as SPT positivity and/or increased IgE levels. Several candidate genes were investigated, and genome-wide linkage analysis was been initiated. The high affinity IgE receptor beta chain (FcepsilonRIbeta) locus showed significant allele sharing in affected sib-pairs for BHR and for SPT positivity. Lymphotoxin alpha (Ltalpha) gene Ncol mutation showed a suggestive linkage with atopy, and the LTalphaNcol 2/2 genotype was found to be associated with increased total IgE levels in all females. No evidence for linkage or association of any phenotype to the tumour necrosis factor alpha (TNFalpha) - 308 mutation or to the interleukin 4 receptor alpha (IL-4Ralpha) Q576R mutation was found. BHR, asthma and increased IgE were found to be linked to X and Y long arm pseudoautosomal region (PAR2) markers. Initial data were also collected from linkage analysis with chromosome 12, 14, and 19, DNA markers. Non-parametric multipoint analysis provides preliminary evidence for linkage of asthma with D12S390, of atopy with D19S601, and of BHR with D14S617. These results suggest that several genetic factors contribute to different allergic asthma phenotypes in the population investigated.

Abstract
Obstructive pulmonary disease is a multifactorial condition deriving from the interaction of environmental and genetic factors. From biochemical knowledge of the basis of the disease, alpha 1-antitrypsin and alpha 1-antichymotrypsin are considered two likely candidate genes. We therefore designed an association study comprising 232 unrelated Italian individuals divided as follows: 89 individuals with obstructive lung disease (66 with COPD and 23 with disseminated bronchiectasis) and 143 controls (45 patients with non-obstructive lung disease and 98 healthy individuals). We screened for Taq I (G1237A) polymorphism of the alpha 1-antitrypsin gene as well as the rare variants Bonn-1 (Pro229Ala), Bochum-1 (Leu55Pro), Isehara-1 (Met389Val) and Isehara-2 (1258delAA), and the common signal peptide polymorphism Thr-15Ala of the alpha 1-antichymotrypsin gene. The frequencies of Taq I G1237A alleles were 11.7 and 10.8% in obstructed patients and controls, respectively (P = 0.43), while those of signal peptide Thr-15Ala alleles were 51.6 and 50.3% in obstructed patients and controls, respectively (P = 0.42). We conclude that alpha 1-antitrypsin Taq I polymorphism and alpha 1-antichymotrypsin Thr-15Ala mutation are not major genetic risk factors for the development of obstructive lung disease in Italian patients. The alpha 1-antichymotrypsin rare variants were not detected: our results do not exclude the possibility that other alpha 1-antichymotrypsin gene mutations might be present in Italian obstructed patients but, if so, these genetic defects must be rare.

Abstract
Tumour necrosis factor (TNF) is a proinflammatory cytokine that increases human airway tissue responsiveness and is considered a candidate gene for asthma. Two common polymorphisms (LTalphaNcoI and TNFalpha-308) in the TNF gene complex were studied in 600 subjects from 131 Italian families with atopic asthmatic children. Skin prick test (SPT), total IgE levels, atopy (defined as increased IgE levels or SPT positivity or both), bronchial hyperresponsiveness, and clinical asthma were investigated. The observed distribution of the identical by descent alleles at the LTalphaNcoI locus was different from expected for SPT and atopy (p=0.015). The LTalphaNcoI genotype distribution for increased IgE levels was different between males and females (p=0.0011), and an association of the 2.2 genotype with increased IgE levels was observed in females (p=0.0032). The results indicate that the LTalpha gene, or a closely linked locus, is associated with atopy, and suggest a sex difference in the effect of the gene.

Abstract
A study of two DNA polymorphisms (i2 RsaI, E237G) in the gene for the beta subunit of the IgE high affinity receptor (FcepsilonRIbeta) was performed in 168 Italian families with atopic asthmatic children. The prevalence of the E237G allele in the Italian population was 4%, so this polymorphism was unsuitable for this study. The i2 RsaI polymorphism minor allele frequency was 44%, and it had a PIC value of 0.37. Linkage analysis indicated a significant allele sharing in affected sib pairs for bronchial hyper-responsiveness (BHR, p=0.048), but not for allergic asthma. These data indicate an association of bronchial hyper-responsiveness with the FcepsilonRIbeta gene.
