Abstract
BackgroundPatients waiting for a kidney transplant by far exceed available organs. AB0 incompatible living donor kidney transplantation (AB0i LDKT) represents an additional therapeutic strategy, but with higher risk for complications. We aimed at evaluating outcomes of AB0i LDKTs compared to compatible (AB0c) controls at our Institution.MethodsRetrospective matched case – control study (1:2) comparing AB0i vs. AB0c LDKTs from March 2012 to September 2021. Considered outcomes: graft function, acute rejection, sepsis, CMV infection, BK virus reactivation, death-censored graft survival, patient survival.ResultsSeventeen AB0i LDKTs matched to 34 AB0c controls. We found excellent graft function, comparable in the two groups, at all considered intervals, with an eGFR (ml/min/1.73 m2) of 67 vs. 66 at 1 year (p = 0.41), 63 vs. 64 at 3 years (p = 0.53). AB0i recipients had a statistically significant higher incidence of acute rejection, acute antibody-mediated rejection and sepsis within 30 days (p = 0.016; p = 0.02; p = 0.001), 1 year (p = 0.012; p = 0.02; p = 0.0004) and 3 years (p = 0.004; p = 0.006; p = 0.012) after surgery. There was no difference in CMV infection, BK virus reactivation, death-censored graft survival between the two groups. Patient survival was inferior in AB0i group at 1 and 3 years (88.2 vs. 100%; log-rank p = 0.03) due to early death for opportunistic infections. AB0i LDKTs spent longer time on dialysis (p = 0.04) and 82.3 vs. 38.3% controls had blood group 0 (p = 0.003).ConclusionsAB0i LDKT is an effective therapeutic strategy with graft function and survival comparable to AB0c LDKTs, despite higher rates of acute rejection and sepsis. It is an additional opportunity for patients with less chances of being transplanted, as blood group 0 individuals.

Abstract
BACKGROUND Patients with colorectal tumour often present with anaemia, and up to 60% will receive red blood cells (RBC) transfusion. Some evidence suggests a correlation between RBC transfusion and worse outcomes. Since laparoscopy minimizes intraoperative blood loss, we retrospectively investigated its role in reducing haemoglobin (Hb) drop and requirements for postoperative RBC transfusions. METHODS Patients were identified from consecutive cases undergone elective surgery for non-metastatic colorectal tumour between 2005 and 2019. Laparoscopic cases were matched 1:1 with open controls through propensity score matching (PSM). The main outcome measures were postoperative Hb drop and requirement for RBC. The secondary aim was evaluation of risk factors for postoperative RBC transfusions. RESULTS After application of PSM, 364 patients treated by laparoscopy were matched with 364 patients undergone open surgery. The two groups presented similar clinical and pathological characteristics, as well as comparable postoperative outcomes. 56 patients in the open group and 47 in the laparoscopic group required postoperative RBC (P = 0.395). No difference was observed in terms of mean number of RBC units (P = 0.608) or Hb drop (P = 0.129). Logistic regression analysis identified preoperative anaemia and occurrence of postoperative complications as relevant risk factors for postoperative RBC transfusion, while surgical approach did not prove statistically significant. CONCLUSION Laparoscopy did not influence postoperative requirements for RBC transfusions after elective colorectal surgery. Preoperative anaemia and occurrence of postoperative complications represent the major determinants for postoperative transfusions after open as well as laparoscopic surgery.

Abstract
Water stress triggers acclimation responses and can damage plants, which varies by species and stress levels. Ongoing climate change is projected to result in longer and more intense water stress conditions leading to an alarming increase in drought-induced forest decline. The aim of this study was to evaluate the physiological responses of leaves and stem wood anatomy from Araucaria araucana pot-grown three-year old seedlings, a conifer tree from northwestern Patagonia. Plants were subjected to moderate and severe water restriction regimes and compared to well-watered controls. Severe water stress reduced relative leaf water content and triggered an accumulation of free proline in leaves, regardless of age. Epicuticular wax extrusions increased in apical leaf stomata while photosynthetic pigments decreased, resulting in differential oxidative damage. The concentration of phenolic compounds was not affected by water restrictions. Plants exposed to restricted water regimes showed diminished middle leaf biomass and expansion (~60% of total leaves), increased stem wood density, and experienced 7% and 30% mortality rates under moderate and severe water stress, respectively. Our findings suggest that under moderate water stress, analogous to short-term droughts, A. araucana seedlings activate physiological mechanisms that allow them to withstand short periods of drought, while more severe water stress and longer droughts can be severely harmful.

Abstract
To test the hypothesis of associations between the ABO blood group system (ABO-bg) and prostate cancer (PCa) features in the surgical specimen of patients treated with robot-assisted radical prostatectomy (RARP). Between January 2013 and October 2020, 1114 patients were treated with RARP. Associations of ABO-bg with specimen pathological features were evaluated by statistical methods. Overall, 305 patients were low risk (27.4%), 590 intermediate risk (50%) and 219 high risk (19.6%). Pelvic lymph node dissection was performed in 678 subjects (60.9%) of whom 79 (11.7%) had cancer invasion. In the surgical specimen, tumor extended beyond the capsule in 9.8% and invaded seminal vesicles in 11.8% of cases. Positive surgical margins (PSM) were detected in 271 cases (24.3%). The most frequently detected blood groups were A and O, which were equally distributed for both including 467 patients (41.9%), followed by groups B (127 cases; 11.4%) and AB (53 subjects; 4.8%). Among specimen factors, the ABO-bgs associated only with the risk of PSM, which was higher for blood group O (30.4%) compared with group A (19.5%) after adjusting for other standard clinical predictors (odds ratio, OR = 1.842; 95% CI 1.352–2.509; p < 0.0001). Along the ABO-bgs, the risk of PSM was increased by group O independently by other standard preoperative factors. The ABO-bgs may represent a further physical factor for clinical assessment of PCa patients, but confirmatory studies are required.

Abstract
Background and aim of the work: Blood loss and transfusion requirements are common in total hip arthroplasty. Tranexamic acid is one of the most interesting options to reduce the need for blood transfusions in a variety of surgical settings. The aim of this study was to assess the efficacy of perioperative intravenous traxexamic acid regarding blood transfusion rate and volume of transfused blood without increasing adverse events after primary elective cementless total hip arthroplasty. Methods: A comparative retrospective study was conducted in 86 healthy patients who had undergone primary cementless total hip artrhoplasty for severe joint diseases at a single institution. All surgical procedures were performed through an anterolateral Watson-Jones approach with the patient in supine position. Forty patients (TXA group) received tranexamic acid 1g as an intravenous bolus 10 minutes before skin incision and a further 1 g, diluted in 250 mL of saline solution, in continuous perfusion at 30 mL/h, following commencement of the surgery. Forty-six patients (control group) did not receive TXA. Outcome measures included BT rate, volume of transfused blood, deep vein thrombosis and occurrence of pulmonary embolism. Results: BT rate was significantly less for the TXA group (37.5%) compared with the control group (65%; p=0.011). The mean blood volume transfused was also significantly less for the TXA group (240 mL) compared with the control group (450 mL; p=0.009). No adverse events occurred in any group. Conclusions: Perioperative intravenous tranexamic acid is effective in reducing blood transfusion rate and volume of transfused blood, without increasing the risk of thromboembolic events in patients undergoing primary cementless total hip arthroplasty.

Abstract
In patients undergoing hematopoietic stem cell transplantation (HSCT), refractoriness to platelet transfusion has been associated with graft failure, delayed engraftment, early mortality and decreased overall survival. Therapeutic strategies include plasma exchange, immunoglobulins, rituximab, and splenectomy. We describe here three patients with refractoriness to platelet transfusion due to anti-human leukocyte antibodies who were splenectomized before HSCT (two cases) and after HSCT (one case) due to the lack of efficacy of other therapies. Splenectomy was uneventful. All three patients achieved a full donor engraftment. We suggest that splenectomy is feasible and effective in HSCT patients to reduce the risk of graft failure or delayed engraftment.

Abstract
The homeodomain-containing transcription factor pancreatic duodenal homeobox 1 (PDX-1) plays a key role in pancreatic development and β-cell function. It is a major regulator of transcription in pancreatic cells, and transactivates the insulin gene by binding to a specific DNA motif in its promoter region. Glucose also regulates insulin gene transcription through PDX-1. It has been shown that PDX-1 is required for maintaining pancreatic islet functions by activating gene expression and has a dual role in pancreatic development. It initially contributes to pancreatic formation during embryogenesis and subsequently regulates the pancreatic islet cell physiology in mature islet cells. Because of this key role in the embryologic development of the pancreas, PDX-1 expression has been investigated in pancreatic cancer cell lines and human tumors. Moreover, a few reports have described expression of PDX-1 in other human neoplasms and have investigated its potential role in differential diagnosis, but data on normal human tissues are lacking. Understanding the molecular mechanisms of pancreas formation, and especially the function of PDX-1, may contribute to the improved treatment and prevention of debilitating diseases such as diabetes, insulinomas and pancreatic carcinomas. Nevertheless, further studies are needed concerning its possible application in routine practice.

Abstract
A critical aspect of blood transfusion is the timely provision of high quality blood products. This task remains a significant challenge for many blood services and blood systems reflecting the difficulty of balancing the recruitment of sufficient donors, the optimal utilization of the donor's gift, the increasing safety related restrictions on blood donation, a growing menu of specialized blood products and an ever-growing imperative to increase the efficiency of blood product provision from a cost perspective. As our industry now faces questions about our standard practices including whether or not the age of blood has a negative impact on recipients, it is timely to take a look at our collective inventory management practices. This International Forum represents an effort to get a snap shot of inventory management practices around the world, and to understand the range of different products provided for patients. In addition to sharing current inventory management practices, this Forum is intended to foster an exchange of ideas around where we see our field moving with respect to various issues including specialty products, new technologies, and reducing recipient risk from blood transfusion products.

Abstract
BACKGROUND Correct identification of individuals with latent tuberculosis infection (LTBI) is a crucial element of the elimination strategy, allowing their adequate treatment. In addition to tuberculin skin test (TST), the Quantiferon test (QFT, based on whole blood gamma-interferon release) had been recently proposed. Aim of the study is to compare this test to TST for identification of LTBI in a non-selected population, in order to verify their value in identifying truly infected individuals (entitled to receive preventive chemotherapy), and to exclude from treatment those having a positive TST for other reasons (e.g. after BCG vaccination). METHODS 136 consecutive persons (78 males, mean age 34 +/- 9 years) referred to the clinic for TST were recruited (78 born in low--or middle--income countries). Based on their history, the cases were divided into 4 groups: 1) recently traced contacts of whom 18 TST negative and 28 TST positive; 2) 22 screening subjects, all TST negative; 3) BCG vaccinated subjects (14); and 4) 54 subjects already undergoing treatment of LTBI for exposure to TB. RESULTS The overall agreement between TST and QFT was 72% (64% in TST positive and 88.4% in TST negative subjects). The proportion of TST positive/QFT negative BCG vaccinated individuals was 23.1%. The K coefficient was 0.474 in recently traced contacts, 0.366 in BCG vaccinated individuals and 0.451 overall. CONCLUSIONS The study results suggest that agreement between TST and QFT is lower in TST positive than in negative subjects, being lower in individuals treated for LTBI. Quantiferon does not seem to have brought significant improvement in the diagnosis of LTBI.

Abstract
This report describes the characterisation of a mycobacterium involved in a case of septic arthritis in an AIDS patient that was treated successfully with specific anti-mycobacterial drugs. The biochemical and cultural features, and the mycolic acid pattern as assessed by high-performance liquid chromatography, were fully compatible with the isolate being Mycobacterium flavescens. However, the isolate's 16S rDNA sequence differed by five nucleotides from the two known sequevars of M. flavescens, thus indicating that this isolate belonged to a new 16S rDNA sequevar.

Abstract
BACKGROUND The implementation of NAT technologies for HIV screening has further reduced the diagnostic window in recent HIV infection. There is still a debate regarding the cost effectiveness of genomic screening of blood donations for transfusion-transmitted viruses (HBV, HCV, HIV). STUDY DESIGN AND METHODS Since October 2001, at the Transfusion Service of Verona, single-donation NAT testing for HCV and HIV-1 (Procleix TMA HIV-1/HCV Assay) of all blood donations has been performed. CASE REPORT A case of acute HIV-1 infection detected by HIV NAT in a repeat blood donor who donated during the preseroconversion window period is reported. All blood components donated were discarded, and the donor started antiretroviral therapy 2 weeks after blood donation. HIV-1 p24 antigen was still negative 10 days after the HIV-1 RNA-positive blood donation. Seroconversion was documented by Day 41 after donation. CONCLUSION This case report testifies that HIV NAT screening of blood donation is effective in preventing the transmission of HIV infection through blood components.

Abstract
The performance of two commercial chromogenic media for the isolation and presumptive identification of urinary tract pathogens, the CPS ID2 (bioMérieux, France) and the CHROMagar Orientation (BBL Becton Dickinson, USA), was evaluated and compared with that of cystine-lactose-electrolyte-deficient agar and tryptic soy agar with 5% sheep blood. The detection, determination of bacterial counts, and presumptive identification of bacteria causing urinary tract infections were evaluated in 3,000 urine specimens. The two chromogenic media showed excellent correlation with the standard media for the detection and the bacterial count of urinary pathogens. The Escherichia coli strains produced the expected colour on the CHROMagar Orientation and the CPS ID2 media in 99% and 90% of the cases, respectively. The Klebsiella-Enterobacter-Citrobacter and the Proteus-Morganella-Providencia groups were easily identified on both chromogenic media, but further biochemical tests were needed to differentiate them to a species level. Both media enabled the differentiation, with varying degrees of difficulty, of Pseudomonas spp. strains from members of the family Enterobacteriaceae. All isolates of Enterococcus spp. were correctly identified and were easily distinguished from the Streptococcus agalactiae isolates. Staphylococcus saprophyticus isolates were easy to identify only on the CHROMagar Orientation medium. No substantial difference was observed when comparing the results of the susceptibility tests, which were performed according to the standardized disk diffusion method as described by the National Committee for Clinical Laboratory Standards, for colonies recovered from the blood agar versus those recovered from the chromogenic media. In conclusion, the CPS ID2 and CHROMagar Orientation media enabled excellent detection, count determination, and presumptive identification of urinary pathogens, both in pure and mixed cultures, and reliable and accurate antimicrobial susceptibility testing directly from primary isolates. Moreover, these media allowed a remarkable reduction in the workload and a significant savings of time. On the basis of their performance, these media can replace the standard primary plating media used in the routine diagnosis of urinary tract infections.

Abstract
The new INNO-LiPA Mycobacteria (Innogenetics, Ghent, Belgium), a reverse-hybridization-based line probe assay, and the AccuProbe assay (Gen-Probe Inc., San Diego, Calif.) were applied to MB/BacT Alert 3D (MB/BacT) system (Organon Teknika, Boxtel, The Netherlands) culture bottles and evaluated for mycobacterial identification. From 2,532 respiratory and extrapulmonary specimens submitted for culture, 168 were flagged positive by the MB/BacT system and promptly evaluated for identification (within 24 h). Each of 163 vials grew one mycobacterial isolate, including Mycobacterium tuberculosis complex (n = 73), M. avium complex (n = 3), M. avium (n = 8), M. intracellulare (n = 5), M. kansasii (n = 15), M. gordonae (n = 8), M. malmoense (n = 3), M. chelonae (n = 13), M. abscessus (n = 2), M. xenopi (n = 11), M. scrofulaceum (n = 2), M. fortuitum (n = 7), M. terrae (n = 3), M. simiae (n = 2), M. celatum (n = 3), M. flavescens (n = 1), M. interjectum (n = 1), M. bohemicum (n = 1), and M. pulveris (n = 2). Five cultures yielded mixed growth of two mycobacterial species: M. tuberculosis complex plus M. gordonae (n = 2), M. tuberculosis complex plus M. chelonae (n = 1), M. tuberculosis complex plus M. xenopi (n = 1), and M. avium plus M. chelonae (n = 1). In testing of one-isolate vials, both systems showed excellent sensitivity and specificity for all species and complexes for which they are licensed (nine for INNO-LiPA Mycobacteria versus six for AccuProbe). There were minor discrepancies in results for two isolates identified by INNO-LiPA Mycobacteria as M. avium - M. intracellulare - M. scrofulaceum (MAIS) complex and by AccuProbe as M. intracellulare. In testing of two-isolate vials, INNO-LiPA Mycobacteria correctly identified all isolates, while the AccuProbe assay failed to identify three M. tuberculosis complex isolates and one M. avium isolate. The AccuProbe assay was completed within 2 h, while INNO-LiPA Mycobacteria required a 6-h period. In our opinion, INNO-LiPA Mycobacteria offers the following advantages: (i) it contains a genus-specific probe that, in addition to being used in genus identification, may be used as an internal control for both the amplification and hybridization steps; (ii) it simultaneously identifies M. tuberculosis complex, MAIS complex, and seven other mycobacterial species, even from mixed cultures; (iii) its mycobacterial DNA amplification ensures reliable results independent from the concentration of viable microorganisms; and (iv) it genotypically identifies M. kansasii and M. chelonae. In conclusion, even though INNO-LiPA Mycobacteria is considerably less easy to use than AccuProbe, requiring personnel skilled in molecular biology techniques, it represents an excellent approach for routine identification of frequently encountered mycobacteria.

Abstract
In B-cell chronic lymphocytic leukemia (B-CLL), defective apoptosis causes the accumulation of mature CD5(+) B cells in lymphoid organs, bone marrow (BM), and peripheral blood (PB). These cells are the progeny of a proliferating pool that feeds the accumulating compartment. The authors sought to determine which molecular mechanisms govern the proliferating pool, how they relate to apoptosis, and what the role is of the microenvironment. To begin to resolve these problems, the expression and modulation of the family of inhibitor of apoptosis proteins (IAPs) were investigated, with consideration given to the possibility that physiological stimuli, such as CD40 ligand (CD40L), available to B cells in the microenvironment, might modulate IAP expression. The in vitro data on mononuclear cells from PB or BM of 30 patients demonstrate that B-CLL cells on CD40 stimulation express Survivin and that Survivin is the only IAP whose expression is induced by CD40L. Through immunohistochemistry, in vivo Survivin expression in lymph node (LN) and BM biopsies was evaluated. In reactive LN, Survivin was detected only in highly proliferating germinal center cells. In LN from patients with B-CLL, Survivin was detected only in pseudofollicles. Pseudofollicle Survivin(+) cells were actively proliferating and, in contrast to Survivin(+) B cells found in normal GC, were Bcl-2(+). In B-CLL BM biopsies, CD5(+), Survivin(+) cells were observed in clusters interspersed with T cells. These findings establish that Survivin controls the B-CLL proliferative pool interfacing apoptosis and that its expression may be modulated by microenvironmental stimuli.

Abstract
Azospirillum species are plant growth-promotive bacteria whose beneficial effects have been postulated to be partially due to production of phytohormones, including gibberellins (GAs). In this work, Azospirillum brasilense strain Cd and Azospirillum lipoferum strain USA 5b promoted sheath elongation growth of two single gene GA-deficient dwarf rice (Oryza sativa) mutants, dy and dx, when the inoculated seedlings were supplied with [17,17-2H2]GA20-glucosyl ester or [17,17- 2H2]GA20-glucosyl ether. Results of capillary gas chromatography-mass spectrometry analysis show that this growth was due primarily to release of the aglycone [17,17-2H2]GA20 and its subsequent 3beta-hydroxylation to [17,17-2H2]GA1 by the microorganism for the dy mutant, and by both the rice plant and microorganism for the dx mutant.

Abstract
BACKGROUND Implant restorations first started with total edentulism. Later, the scientific community gave its approval for restorations in partial edentulism, and only recently some studies confirmed the validity of the treatment for single-tooth replacement. PURPOSE The purpose of the study was to evaluate implant survival and prosthesis stability of Brånemark implants (titanium screws) when used routinely for single-tooth replacement in all regions. MATERIALS AND METHODS Two hundred and fourteen patients received 252 implants for single-tooth replacement over a period of 8 years at five private clinics in Italy. The patients were treated in accordance with the protocol for Brånemark implants, and the data gathered have been analyzed according to established evaluation methods. RESULTS During the observation period, 10 failures were recorded and 229 restorations were carried out. After the first year of loading, the total cumulative survival rate (CSR) was 96%, which then remained stable over the study time. The most frequent complication was loosening of the abutment screws (n = 22), amounting to 35% of all of the complications. This problem was related mainly to earlier types of abutments, whereas the more recent design, CeraOne abutment, showed a low frequency of screw loosening. CONCLUSIONS The high survival rate, which is similar to that presented for prospective multicenter studies for single-tooth restorations with Brånemark implants, led to the conclusion that the use of this treatment modality is a reliable treatment for routine use in all oral regions.

Abstract
The new Roche COBAS AMPLICOR Mycobacterium tuberculosis Assay was compared to the Gen-Probe enhanced Mycobacterium tuberculosis Amplified Direct Test (AMTDII). A total of 486 specimens (296 respiratory and 190 extrapulmonary) collected from 323 patients were tested in parallel with both assays. Results were compared with those of acid-fast staining and culture, setting the combination of culture and clinical diagnosis as the "gold standard." After resolution of discrepant results, the sensitivity, specificity, and positive and negative predictive values for AMTDII were 85.7, 100, 100, and 90.4% for respiratory specimens and 82.9, 100, 100, and 95. 5% for extrapulmonary specimens, respectively. The corresponding values for AMPLICOR were 94.2, 100, 100, and 96.6% for respiratory specimens and 85, 100, 100, and 96.1% for extrapulmonary specimens, respectively. No significant differences were observed between the results of both assays or, within each one, between respiratory and extrapulmonary specimens. The difference between AMTDII and AMPLICOR sensitivities was related to the presence of inhibitory samples, which the former assay, lacking an internal amplification control (IAC), could not detect. The overall inhibition rate for the AMPLICOR assay was 3.9% (19 specimens). It is concluded that, although both amplification assays proved to be rapid and specific for the detection of M. tuberculosis complex in clinical samples, AMPLICOR, by a completely automated amplification and detection procedure, was shown to be particularly feasible for a routine laboratory setting. Finally, AMTDII is potentially an excellent diagnostic technique for both respiratory and extrapulmonary specimens, provided that an IAC is included with the assay.

Abstract
BACKGROUND Describing the epidemiology of varicella is relevant to the development of specific prevention strategies and to building up of economic models evaluating the cost:efficiency ratios of these strategies. AIM Our study was designed to describe the epidemiology of chickenpox among Italian children and to assess the resulting economic and health burden on the country. METHODS Thirty-nine Italian pediatricians participated in a sentinel network on pediatric infectious diseases representing a total pediatric population of 30 168 children. Each case of varicella observed from January through December, 1997, was recorded. Economic analysis was conducted from the societal point of view. All costs were broken down into two groups: direct and indirect costs. RESULTS A total of 1599 cases of varicella were reported among children 0 to 14 years old. There were 1266 primary cases (mean age, 4.5 +/- 2 years) and 333 secondary cases (mean age, 3.6 +/- 3.2 years). The global incidence of chickenpox was 51.01/1000/year. Complications were seen in 56 cases (3.5%). Drugs were prescribed in 672 cases. A group of adults (364 susceptible and 193 with uncertain status) were exposed to primary cases. Seventy (12.5%) were eventually infected among whom there were 4 pregnant women. For pediatric patients an average cost of $146.90 (250 400 lire) was estimated; this is largely accounted for by indirect costs. CONCLUSIONS The epidemiology of varicella in Italy is consistent with that found in previous studies in industrialized countries. Severe complications did not occur in our population. We believe that the health arguments in favor of universal vaccination of children > 18 months of age do not differ in our own country from those of other industrialized nations. Our data could now be incorporated into pharmacoeconomic models to establish cost-efficient strategies for Italy.

Abstract
A new autosomal-dominant genetic disorder, which has been recently identified by our group is described. The disease is clinically characterized by the combination of a substantial increase of serum ferritin and early-onset bilateral cataract. Moreover, it is clearly distinguishable from genetic hemochromatosis because of: 1) normal to low serum iron and transferrin saturation, without evidence of parenchymal iron overload; 2) the dominant transmission; 3) the lack of any relation with HLA; 4) the rapid development of iron-deficient anemia when unnecessary phlebotomies are performed. The molecular basis of the new syndrome is a mutation in the L-subunit ferritin gene on chromosome 19 (19q13.3-->19qter). The mutation involves a five nucleotide sequence [CAGUG] of the iron-responsive-element (IRE), which is critical for the post-transcriptional regulation of ferritin synthesis by means of the binding with an Iron Regulatory Protein. As a consequence, ferritin synthesis is up-regulated, irrespective of cell iron status.

Abstract
BACKGROUND The role of HLA-DP as transplantation antigen in contributing to GvHD is a matter of current debate. HLA-DP, is encoded centromeric to DR-DQ and its alleles are in weak linkage disequilibrium with the rest of the MHC; thus a certain number of HLA matched pairs could be actually DP incompatible to study a possible correlation between HLA-DP matching and GvHD, 24 HLA identical BMT/donor-recipient sibling pairs (serologically tested for HLA Class I and DR antigens) were tested for DQ and DP genes using restriction fragment length polymorphism (RFLP) analysis. METHODS DNA extracts were digested according to a standard procedure with two different restriction enzymes (HIND III and MSP I) and hybridised with DQ (alpha and beta) and DP (alpha and beta) specific probes. Highly stringent hybridization and washing conditions were used to prevent cross-hybridizations. RESULTS Twenty four out of 24 pairs proved to be DQ and DP identical. GvHD developed in 16 out of 24 (66.6%) recipients. DISCUSSION These data suggest that DNa analysis of DQ-DP regions, with the probes and enzymes used, does not give predictive informations for GvHD in HLA genotypically identical pairs.

Abstract
The high incidence of third molar extraction is related to their frequent pathology. The use of an uncomplicated and reliable diagnostic and therapeutic protocol therefore became extremely important. The protocol has to include careful selection and preparation as well as the appropriate choice of instruments and surgical techniques. This is even more important, considering the elective nature of the procedure and the local and more rarely, systemic complications that could develop.
