Abstract
BACKGROUND This systematic review integrated the available data published in the literature on Stafne's bone defect (SBD), considering the clinical, imaging and histopathological results. MATERIAL AND METHODS An electronic search was undertaken in six databases. Eligibility criteria were: articles in English, Spanish, and Portuguese describing case reports or case series of SBD, reported up to September/2021. Risk of bias was assessed using the Joanna Briggs Institute tool. RESULTS A total of 98 articles were retrieved, involving 465 individuals with SBD and were included for quantitative analysis. Mean age was 52.78 years (range: 11-89 years), with male predilection (n=374/80.85%). Radiographs were the most frequent imagiological exams (n=298/64.09%), followed by computed tomography (n=98/21.08%). SBD was more prevalent in the posterior mandible (n=361/93.77%) as a hypodense radiolucent lesion (n=250/77.40%). Mean size was 1.58 cm (range: 0.3-.8.0 cm). Two-hundred-and-two lesions (97.37%) were unilocular and 126 (91.97%) were classified as well-defined. Clinical symptoms were reported in 73 cases, while 68 cases (93.15%) were asymptomatic. Only 34 cases (12.32%) were submitted to histopathological examination. Mean follow-up time was 26.42 ±25.39 months. CONCLUSIONS SBD is more frequent in male patients in the fifth and sixth decade of life. Classic SBD is radiographically characterized as a single, unilocular and well-defined lesion in the posterior region of the jaw with a radiolucent/hypodense appearance.

Abstract
RationaleNontuberculous Mycobacterial (NTM) diseases are difficult to treat infections, especially in lung transplant (LTx) candidates. Currently, there are paucity of recommendations on the management of NTM infections in LTx, focusing on Mycobacterium avium complex (MAC), M.abscessus(MAB), and M.kansasii(MK).MethodsPulmonologists, infectious disease specialists, LTx surgeons, and Delphi experts with expertise in NTM were recruited. A patient representative was also invited. Three questionnaires were distributed to panelists comprising of questions with multiple response statements. Delphi methodology with a Likert scale of 11 points (5 to −5) was applied to define the agreement between experts. Responses from the first two questionnaires were collated to develop a final questionnaire. The consensus was described as a median rating >4 or <- four indicating for or against the given statement. After the last round of questionnaires, a cumulative report was generated.ResultsPanelists recommend performing sputum cultures and a chest CT scan for NTM screening in lung transplant candidates. Panelists recommend against absolute contraindication to LTx even with multiple positive sputum cultures for MAC, M.abscessus,or M.kansasii.Panelists recommend MAC patients on antimicrobial treatment and culture harmful can be listed for LTx without further delay. Panelists recommend six months of culture-negative for M.kansasii, whereas a 12-month further treatment from the time of culture-negative for M.abscessusbefore listing for LTx.ConclusionNTM LTx study consensus statement has provided essential recommendations in NTM management in LTx and can be utilized as an expert opinion while awaiting evidence-based contributions.

Abstract
The last decade has seen an explosion of advanced assays for the diagnosis of infectious diseases, yet evidence-based recommendations to inform their optimal use in the care of transplant recipients are lacking. A consensus conference sponsored by the American Society of Transplantation (AST) was convened on December 7, 2021, to define the utility of novel infectious disease diagnostics in organ transplant recipients. The conference represented a collaborative effort by experts in transplant infectious diseases, diagnostic stewardship, and clinical microbiology from centers across North America to evaluate current uses, unmet needs, and future directions for assays in 5 categories including (1) multiplex molecular assays, (2) rapid antimicrobial resistance detection methods, (3) pathogen-specific T-cell reactivity assays, (4) next-generation sequencing assays, and (5) mass spectrometry-based assays. Participants reviewed and appraised available literature, determined assay advantages and limitations, developed best practice guidance largely based on expert opinion for clinical use, and identified areas of future investigation in the setting of transplantation. In addition, attendees emphasized the need for well-designed studies to generate high-quality evidence needed to guide care, identified regulatory and financial barriers, and discussed the role of regulatory agencies in facilitating research and implementation of these assays. Findings and consensus statements are presented.

Abstract
Background Accurate population estimates of disease incidence and burden are needed to set appropriate public health policy. The capture–recapture (C‐R) method combines data from multiple sources to provide better estimates than is possible using single sources. Methods Data were derived from clinical virology test results and from an influenza vaccine effectiveness study from seasons 2016–2017 to 2018–2019. The Petersen C‐R method was used to estimate the population size of influenza cases; these estimates were then used to calculate adult influenza hospitalization burden using a Centers for Disease Control and Prevention (CDC) multiplier method. Results Over all seasons, 343 influenza cases were reported in the clinical database, and 313 in the research database. Fifty‐nine cases (17%) reported in the clinical database were not captured in the research database, and 29 (9%) cases in the research database were not captured in the clinical database. Influenza hospitalizations were higher among vaccinated (58%) than the unvaccinated (35%) in the current season and were similar among unvaccinated (51%) and vaccinated (49%) in the previous year. Completeness of the influenza hospitalization capture was estimated to be 76%. The incidence rates for influenza hospitalizations varied by age and season and averaged 307–309 cases/100,000 adult population annually. Conclusion Using C‐R methods with more than one database, along with a multiplier method with adjustments improves the population estimates of influenza disease burden compared with relying on a single‐data source.

Abstract
We observed decreased effectiveness of influenza vaccine with increasing time since vaccination for prevention of influenza A(H3N2), influenza A(H1N1)pdm09, and influenza B/Yamagata-associated hospitalizations among adults. Maximum vaccine effectiveness (VE) was observed shortly after vaccination, followed by an absolute decline in VE of about 8%-9% per month postvaccination.

Abstract
We estimated vaccine effectiveness (VE) for prevention of influenza-associated hospitalizations among adults during the 2018-2019 influenza season. Adults admitted with acute respiratory illness to 14 hospitals of the US Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN) and testing positive for influenza were cases; patients testing negative were controls. VE was estimated using logistic regression and inverse probability of treatment weighting. We analyzed data from 2863 patients with a mean age of 63 years. Adjusted VE against influenza A(H1N1)pdm09-associated hospitalization was 51% (95% confidence interval [CI], 25%-68%). Adjusted VE against influenza A(H3N2) virus-associated hospitalization was -2% (95% CI, -65% to 37%) and differed significantly by age, with VE of -130% (95% CI, -374% to -27%) among adults 18 to ≤56 years of age. Although vaccination halved the risk of influenza A(H1N1)pdm09-associated hospitalizations, it conferred no protection against influenza A(H3N2)-associated hospitalizations. We observed negative VE for young and middle-aged adults but cannot exclude residual confounding as a potential explanation.

Abstract
Background Accurate population estimates of disease incidence and burden are needed to set appropriate public health policy. The capture-recapture (C-R) method combines data from multiple sources to better estimate prevalence than is possible using single sources. This study used the C-R method to estimate influenza cases using research and administrative databases to calculate county-wide influenza hospitalization burden. Methods Data were derived from a database of clinical virology test results and research data from an influenza vaccine effectiveness study from seasons 2015-2016 to 2018-2019. Missed influenza cases were estimated using C-R method. These estimates were used to calculate disease burden using the multiplier method to correct for underreporting due to curtailing data collection before the end of influenza circulation. Results Over all seasons, 422 influenza cases were reported in the administrative database and 382 influenza cases in the research database. Seventy-five cases (18%) reported in the administrative database were not captured in the research database, and 35 (9%) cases in the research database were not captured in the administrative database. Completeness of the influenza hospitalization was estimated to be 76%. Influenza hospitalizations were higher among unvaccinated (32%) than vaccinated (22%) in the current season and among unvaccinated (28%) than vaccinated (23%) in the previous year. The incidence rates for influenza hospitalizations varied by age and season and averaged 421 cases/100,000 population annually. Conclusion The capture-recapture method offers a more accurate method for estimating influenza hospitalization than relying on a single data source. Using the multiplier method with adjustments improves the detection of influenza disease burden through a matched database. The incidence rates are consistent with national estimates.

Abstract
OBJECTIVES To describe the use, complications and outcome of temporary tracheostomy tube placement as part of the management of acute upper airway obstruction in the postoperative period following multi-level airway surgery in patients with brachycephalic obstructive airway syndrome. MATERIALS AND METHODS Retrospective review of records of dogs surgically treated for brachycephalic obstructive airway syndrome that had a temporary tracheostomy tube placed in the postoperative period. RESULTS Forty-two dogs were included. Median duration of temporary tracheostomy tube placement was 2 days (range 1 to 7). The major complication rate was 83.3%, minor complication rate was 71.4%, resulting in an overall postoperative complication rate of 95.2%. The most common postoperative complications were tracheostomy tube obstruction (32/42), cough (25/42) and tracheostomy tube dislodgement (16/42). Temporary tracheostomy tube management was classified as successful in 97.6%. Dyspnoea was the most common clinical sign in the short-term postoperative follow-up period, while dyspnoea and increased upper respiratory tract noise were the most common clinical sign in the long term. The median duration of follow-up was 251 days. CLINICAL SIGNIFICANCE In an appropriate clinical setting, placement of temporary tracheostomy tubes following multi-level airway surgery for brachycephalic obstructive airway syndrome is a useful strategy to manage postoperative airway obstruction, carrying a low mortality rate, and with a complication rate similar to that found in previous reports.

Abstract
Root fractures resulting from dental trauma involve dentin, cementum and pulp. The present study aimed to demonstrate the importance of cone-beam computed tomography (CBTC) and bioceramics in the correct planning and intervention of a horizontal root fracture case in tooth 11 with late treatment in an 18-year-old patient. Clinical and radiographic examinations revealed tooth displacement, pain on vertical percussion and images suggestive of a horizontal root fracture. Pulp necrosis was diagnosed and CBTC was requested for treatment planning. Subsequently, endodontic treatment was performed using a bioceramic apical plug. A 2-year follow-up indicated the absence of root resorption and normal periodontal and periapical tissues. It was concluded that endodontic treatment associated with the use of bioceramics and the aid of CBTC is an effective therapeutic option in cases of permanent horizontal root fractures.

Abstract
RATIONALE Cytomegalovirus (CMV)-related morbidities remain one of the most common complications after lung transplantation and have been linked to allograft dysfunction, but the factors that predict high risk for CMV complications and effective immunity are incompletely understood. OBJECTIVES To determine if short telomeres in idiopathic pulmonary fibrosis (IPF) lung transplant recipients (LTRs) predict the risk for CMV-specific T-cell immunity and viral control. METHODS We studied IPF-LTRs (n = 42) and age-matched non-IPF-LTRs (n = 42) and assessed CMV outcomes. We measured lymphocyte telomere length and DNA sequencing, and assessed CMV-specific T-cell immunity in LTRs at high risk for CMV events, using flow cytometry and fluorescence in situ hybridization. MEASUREMENTS AND MAIN RESULTS We identified a high prevalence of relapsing CMV viremia in IPF-LTRs compared with non-IPF-LTRs (69% vs. 31%; odds ratio, 4.98; 95% confidence interval, 1.95-12.50; P < 0.001). Within this subset, IPF-LTRs who had short telomeres had the highest risk of CMV complications (P < 0.01) including relapsing-viremia episodes, end-organ disease, and CMV resistance to therapy, as well as shorter time to viremia versus age-matched non-IPF control subjects (P < 0.001). The short telomere defect in IPF-LTRs was associated with significantly impaired CMV-specific proliferative responses, T-cell effector functions, and induction of the major type-1 transcription factor T-bet (T-box 21;TBX21). CONCLUSIONS Because the short telomere defect has been linked to the pathogenesis of IPF in some cases, our data indicate that impaired CMV immunity may be a systemic manifestation of telomere-mediated disease in these patients. Identifying this high-risk subset of LTRs has implications for risk assessment, management, and potential strategies for averting post-transplant CMV morbidities.

Abstract
UNLABELLED We evaluate 38 elderly women who had received long-term denosumab treatment after stopping the drug. Taking into account the gain during treatment and the loss after stopping treatment, they lost 35.5% of the total gain in the spine, 44.6% of the total gain in the femoral neck, and 103.3% in the total hip. INTRODUCTION Denosumab (DMAb) is a soluble inhibitor of the receptor activator of nuclear factor-kappaB ligand (RANKL) and, therefore, does not incorporate into the bone matrix. Consistently, DMAb discontinuation is associated with reversal of the effects attained with treatment. PURPOSE The aim of this study is to assess changes in BMD after a year of discontinuation of DMAb in a group of postmenopausal women treated with DMAb for 7 or 10 years. Secondly, is to evaluate the occurrence of fragility fractures. METHODS Women who had participated in the FREEDOM study and its extension were invited to participate in this follow-up study. BMD at LS and hip and spine X-rays were obtained. Results were compared to the last value obtained while in treatment to assess changes after discontinuation. RESULTS Thirty-eight women, mean age: 81 ± 3.4 years completed study procedures; none had received bisphosphonates after stopping DMAb. Mean gap time between DMAb last dose and the follow-up visit was 17 months (range 16-20 months). Bone mineral density (BMD) decreased significantly in all regions: - 8.1% in LS, - 6% in FN, and - 8.4% in TH. Five (5/38, 13.15%) patients had a fragility fracture, one suffered a wrist fracture, and four experienced vertebral fractures. Three patients suffered one vertebral fracture and one of them had two vertebral fractures. Laboratory results showed the following mean values: CTX = 996 ± 307 pg/ml (normal values 550 ± 226 pg/ml); osteocalcin = 55.2 ± 18.6 ng/ml (normal value 42 ng/ml); and 25 OH vitamin D = 23.7 ± 6.9 ng/ml. CONCLUSION Our results describe the rapid bone loss occurring after cessation of denosumab treatment. Further studies are needed to assess if patients have a higher risk of fracture after stopping DMAb and if so, which patients have the highest risk, and assess the role of transitioning to bisphosphonates in the long term.

Abstract
Detection and analysis of virulence-associated genes (VAGs) of avian pathogenic Escherichia coli (APEC) may be helpful to distinguish pathogenic from commensal faecal strains (AFEC). The aim of this study was to characterise 120 isolates of avian Escherichia coli, comprising 91 APEC (from diseased birds) and 29 AFEC (from healthy chickens), collected in Brazil. Phylogenetic analysis and in vivo pathogenicity testing was performed on 38 VAGs. The VAGs iucD, iutA, iroN, fepC, ompT, cvi and hlyF were statistically associated with medium and high pathogenicity (MP/HP) strains. A minimal group of seven VAGs may be required to accurately discriminate pathogenic and non-pathogenic avian strains of E. coli in Brazil.

Abstract
Although Trypanosoma cruzi, the parasite that causes Chagas disease, can be transmitted via organ transplantation, liver and kidney transplantation from infected donors may be feasible. We describe the outcomes of 32 transplant recipients who received organs from 14 T. cruzi seropositive donors in the United States from 2001 to 2011. Transmission was confirmed in 9 recipients from 6 donors, including 3 of 4 (75%) heart transplant recipients, 2 of 10 (20%) liver recipients and 2 of 15 (13%) kidney recipients. Recommended monitoring posttransplant consisted of regular testing by PCR, hemoculture, and serology. Thirteen recipients had no or incomplete monitoring; transmission was confirmed in five of these recipients. Four of the five recipients had symptomatic disease and all four died although death was directly related to Chagas disease in only one. Nineteen recipients had partial or complete monitoring for T. cruzi infection with weekly testing by PCR, hemoculture and serology; transmission was confirmed in 4 of 19 recipients with no cases of symptomatic disease. Our results suggest that liver and kidney transplantation from T. cruzi seropositive donors may be feasible when the recommended monitoring schedule for T. cruzi infection is followed and prompt therapy with benznidazole can be administered.

Abstract
UNLABELLED Hemodialyzed patients have decreased bone strength not completely characterized. We evaluated bone microarchitecture in hemodialysis patients and compared it to that of subjects without renal disease by high-resolution peripheral quantitative computed tomography (HR-pQCT). Hemodialysis patients have a marked decreased in cortical density, thickness, and area with significant reduction in trabecular parameters that correlated with the severity of secondary hyperparathyroidism only in women. INTRODUCTION Although fracture risk is greatly increased in dialysis patients, the corresponding decreased in bone strength has not been completely characterized. METHODS We evaluated volumetric bone mineral density (vBMD) and bone microstructure by HR-pQCT at the distal radius and tibia in 50 hemodialyzed (HD) patients (30 females, mean age 53.2 ± 6 years and 20 males, mean age 59.1 ± 11 years) and 50 sex- and age-matched controls. RESULTS At the distal radius HD, women showed a 29% reduction in total and trabecular density and trabecular bone volume fraction (p < 0.0001) compared to controls. Trabecular number was reduced by 25% (p < 0.0001), while trabecular separation was increased by 51%. Cortical thickness (-40%, p < 0.0001) and cortical area (-42%, p < 0.0001) were the parameters most reduced, while compact density was the parameter least reduced (-15%, p < 0.0001). Similar findings were found at the tibia. In HD men, HR-pQCT at the distal radius and tibia showed a reduction in volumetric density and microstructure parameters to a lesser extent than in women. In the hemodialyzed group, cortical thickness at the radius was negatively correlated with age both in women and men. At the distal radius and tibia, we found significant negative correlations between Log iPTH and total alkaline phosphatase with cortical vBMD(r = -0.48, p < 0.01; r = -0.69, p < 0.001), thickness (-0.37, p < 0.05; r = -0.60, p < 0.001), and area ((r = -0.43, p = 0.02; r = -0.65, p < 0.001) but only in women. CONCLUSION We conclude that hemodialysis patients have a marked decreased in cortical density, thickness, and area with significant reduction in trabecular parameters that correlated with the severity of secondary hyperparathyroidism only in women.

Abstract
Alphitobius diaperinus, conhecido como cascudinho, é encontrado abundantemente nas instalações avícolas, e acarreta prejuízos zootécnicos e sanitários na avicultura industrial mundialmente. As formas de controle deste besouro estão baseadas exclusivamente no uso de inseticidas para os quais já existem vários relatos de populações resistentes forçando o emprego de métodos alternativos como o controle biológico, interferindo no ciclo de vida do inseto. Este estudo avaliou, em condições de laboratório, a mortalidade de larvas e adultos de A. diaperinus frente a diferentes temperaturas de aquecimento (45º, 50º, 55º e 60º C) e resfriamento (-10º, -13º e -18º C), na presença de maravalha (PM) e ausência de maravalha (AM), através do tempo letal de 100% dos insetos (TL100) em minutos em cada temperatura. A TL100 de larvas e adultos em 45º C foi de 36 e 38 AM e 42 e 57 PM, em 50º C foram 15 e 11 AM e 19 e 16 PM, para 55º C foi de 8 e 9 AM e 12 PM e em 60º C foi de 5 e 6 AM e 11 e 9 PM. Já em -10º C variou de 57 e 60 AM e 70 e 75 PM, em -13º C levou 52 e 55 AM e 60 e 64 PM e em -18º C levou 42 e 43 AM e 51 e 52 PM. Em todas as temperaturas avaliadas houve mortalidade dos insetos em tempo consideravelmente rápido e métodos de controle, através da temperatura, devem levar em consideração esses pontos para referência.

Abstract
After decades of controversy surrounding the therapeutic validity of pancreas transplantation, the procedure has become accepted as the preferred treatment for selected patients with type 1 diabetes mellitus. Between January 2001 and January 2008, 100 patients underwent pancreatic transplantation at our center: 88 simultaneous pancreas-kidney transplantation and 12 pancreas transplantations alone. Pancreas graft management of the exocrine drainage technique involved enteric drainage in 8 (all simultaneous pancreas-kidney) and the bladder in 92 cases. The recipient systemic venous system was used for the pancreas graft venous effluent in all cases. Our overall results have shown that the number of functioning pancreatic grafts was 64 of 100. Graft losses were: rejection (n = 8), venous thrombosis (n = 9), arterial thrombosis (n = 1), or surgical complications such as anastomotic leak (n = 3), perigraft infection (n = 10), pancreatitis of the graft (n = 5). Most cases of pancreatitis (80%) had preservation times exceeding 18 hours. Despite surgical and immunosuppressive complications, our impression was that pancreas transplantation was a highly effective therapy for diabetes mellitus. After 7 years of the program and 100 transplantations, we believe that there is a major role for transplantation in diabetes management.

Abstract
AIM To report the simultaneous endodontic and surgical treatment of a tooth associated with Oehlers type III dens invaginatus and a persistent periapical lesion, which comprised root-end resection, root-end filling and application of a calcium hydroxide barrier placed on the resected dentine surface. SUMMARY Three root canals were identified in a tooth with a type III dens invaginatus, which presented with a necrotic pulp, wide foraminal opening and extensive periapical lesion, and with a previous history of acute abscess, intracanal exudate and fistula. After root canal preparation followed by intracanal application of calcium hydroxide pastes, the clinical-pathological status persisted. After periapical curettage and root-end resection, the root canals were filled, followed by root-end filling with Sealer 26 mixed with zinc oxide powder to a clay-like consistency. Calcium hydroxide paste was then applied over the exposed dentinal surface forming a covering over the root apex. At the 20-month follow-up examination the patient had no symptoms and no fistula; advanced periapical bone repair was obvious on the radiograph. KEY LEARNING POINTS Because of the variable morphology and extent of invagination, type III dens invaginatus represents a challenge for conventional treatment, often leading to the need for a surgical approach. Sealer 26 thickened with zinc oxide powder provided satisfactory clinical properties for use as a root-end filling material. Application of a calcium hydroxide barrier over the resected root-end is a potential treatment option to encourage tissue repair.

Abstract
Significant early bleeding is one of the surgical complications following simultaneous pancreas-kidney transplantation that has historically shaped the procedure. The consequence, exploratory laparotomy, carries high morbidity levels and elevated costs for the health system. Angiographic intervention is already a common procedure for the treatment of late, but not early, vascular complications. We describe a case of an early vascular complication that was successfully treated with angiographic embolization in a to simultaneous pancreas-kidney transplant patient.

Abstract
A genome-wide scan was conducted for visceral leishmaniasis (VL) in Brazil. Initially, 405 markers were typed in 22 multicase pedigrees (28 nuclear families; 174 individuals; 66 affected). Non-parametric multipoint analysis detected nine chromosomal regions with provisional evidence (logarithm of the odds (LOD) scores 0.95-1.66; 0.003<P<0.018) for linkage. To confirm linkage, 132 individuals (43 affected) from 19 independently ascertained families were genotyped across these regions. Three regions (6q27, 7q11.22 and 17q11.2-q21.3) retained evidence (LOD scores 1.08, 1.34, 1.14; P=0.013, 0.007, 0.011) for linkage. To determine which genes contribute to linkage at 17q11.2-q21.3, 80 single nucleotide polymorphisms were genotyped in 98 nuclear families with 183 affected individuals. Family-based association test analysis indicated associations at two chemokine genes, CCL1 and CCL16, that lie 1.6 Mb apart, show some extended linkage disequilibrium with each other, but each lie within different clusters of candidate CCL genes. Multiple genes may therefore contribute to the linkage peak for VL at 17q12.

Abstract
We investigated ertapenem-susceptible and -resistant extended-spectrum beta-lactamase-producing Enterobacter cloacae isolates obtained from the same patient. Gene transcription of OmpD and OmpF was diminished in the ertapenem-resistant isolate. An efflux pump inhibitor decreased the MICs of ertapenem in the resistant strain, suggesting a potential role of efflux pumps in ertapenem resistance.

Abstract
AIM To report the repair of an extensive periapical lesion of endodontic origin, following nonsurgical treatment. SUMMARY Clinical and radiographic examination revealed an extensive periapical lesion related to tooth 22, extending from the distal surface of tooth 21 to the mesial surface of 26. The patient reported a previous history of dental trauma involving this quadrant and had been under orthodontic treatment for a year. Intraoral examination revealed an asymptomatic bony hard swelling, mainly confined to the palate. During root canal exploration irregular walls associated with 3 mm of apical calcification were noted. After apical patency was obtained 1 mL of bloody serous exudate was drained. Intracanal aspiration provided a further 2 mL of yellow serous exudate. Following biomechanical preparation, a dressing of calcium hydroxide with anaesthetic solution was applied and replaced four times over a period of 12 months. The clinical-pathological picture demonstrated resolution of the lesion during this period of time. The 14-month clinical and radiographic examinations revealed normal bony contour and a significant resolution of the maxillary radiolucency. KEY LEARNING POINTS Periapical lesions of endodontic origin may develop asymptomatically and become large. Proper biomechanical preparation followed by calcium hydroxide medication renewed periodically represents a nonsurgical approach to resolve extensive inflammatory periapical lesions.

Abstract
Cefepime is a potentially useful antibiotic for treatment of infections with Enterobacter cloacae. However, in our institution the MIC(90) for E. cloacae bloodstream isolates is 16 microg/ml. PCR amplification of bla genes revealed that one-third (15/45) of E. cloacae bloodstream isolates produced SHV-type extended-spectrum beta-lactamases (ESBLs) in addition to hyperproduction of AmpC-type beta-lactamases. The majority (11/15) of ESBL producers also produced the TEM-1 beta-lactamase. The SHV types included SHV-2, -5, -7, -12, -14, and -30. All but two of the ESBL-producing E. cloacae isolates, but none of the non-ESBL-producing strains, had MICs of cefepime of >or=2 microg/ml. The MIC(90) for cefepime for ESBL-producing strains was 64 mug/ml, while for non-ESBL producers it was 0.5 microg/ml. Using current Clinical and Laboratory Standards Institute breakpoints for cefepime, two thirds (10/15) of ESBL-producing isolates would have been regarded as susceptible to cefepime. Phenotypic ESBL detection methods were generally unreliable with these E. cloacae isolates. Based on these results, pharmacokinetic, pharmacodynamic, and clinical reevaluation of cefepime breakpoints for E. cloacae may be prudent.

Abstract
PURPOSE OF REVIEW Invasive fungal infections of the lung have historically been associated with an extremely high mortality. This review aims to disseminate the most recent advances in the diagnosis and management of fungal infections of the lung. RECENT FINDINGS The number and diversity of immunosuppressed populations are growing rapidly. Transplant immunosuppression is becoming more aggressive early in the posttransplant period, potentially increasing the risk of invasive fungal infections. The galactomannan antigen test and the beta-D-glucan test have emerged as methods of serially monitoring at-risk patients for invasive aspergillosis. Their utility has been established in some neutropenic populations but not in solid organ transplant recipients. In-vitro studies, animal studies, and retrospective human studies support the use of combination antifungal therapy for invasive aspergillosis. Unfortunately no randomized clinical trials exist. SUMMARY Invasive pulmonary aspergillosis will continue to be a major problem in immunocompromised patients in the future. Immense advances in the last 2-3 years are sure to improve outcome. Well-designed multicenter evaluations are still necessary, however, to optimize management as management options widen.

Abstract
The common causes of ventilator-associated pneumonia (Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterobacter cloacae, Acinetobacter spp) are frequently resistant to multiple antibiotic classes. S aureus develops resistance to all beta-lactam antibiotics by producing a modified penicillin-binding protein. Linezolid resistance arises by way of mutations in the 23S ribosomal subunit. Antibiotic resistance in gram-negative bacilli usually arises by way of beta-lactamase production, upregulation of efflux pumps, or loss of outer membrane proteins. The ability of bacteria to develop and disseminate new mechanisms of antibiotic resistance may outstrip the availability of new antibiotic classes.

Abstract
Genome-wide scans were conducted for tuberculosis and leprosy per se in Brazil. At stage 1, 405 markers (10 cM map) were typed in 16 (178 individuals) tuberculosis and 21 (173 individuals) leprosy families. Nonparametric multipoint analysis detected 8 and 9 chromosomal regions respectively with provisional evidence (P<0.05) for linkage. At stage 2, 58 markers from positive regions were typed in a second set of 22 (176 individuals) tuberculosis families, with 22 additional markers typed in all families; 42 positive markers in 50 (192 individuals) new leprosy families, and 30 additional markers in all families. Three regions (10q26.13, 11q12.3, 20p12.1) retained suggestive evidence (peak LOD scores 1.31, 1.85, 1.78; P=0.007, 0.0018, 0.0021) for linkage to tuberculosis, 3 regions (6p21.32, 17q22, 20p13) to leprosy (HLA-DQA, 3.23, P=5.8 x 10(-5); D17S1868, 2.38, P=0.0005; D20S889, 1.51, P=0.004). The peak at D20S889 for leprosy is 3.5 Mb distal to that reported at D20S115 for leprosy in India. (151 words).
