Abstract
Background COVID‑19 is a novel cause of acute respiratory distress syndrome (ARDS) that leads patients to intensive care unit (ICU) admission requiring invasive ventilation, who consequently are at risk of developing of ventilator‑associated pneumonia (VAP). The aim of this study was to assess the incidence, antimicrobial resistance, risk factors, and outcome of VAP in ICU COVID-19 patients in invasive mechanical ventilation (MV). Methods Observational prospective study including adult ICU admissions between January 1, 2021, and June 31, 2021, with confirmed COVID-19 diagnosis were recorded daily, including demographics, medical history, ICU clinical data, etiology of VAPs, and the outcome. The diagnosis of VAP was based on multi-criteria decision analysis which included a combination of radiological, clinical, and microbiological criteria in ICU patients in MV for at least 48 h. Results Two hundred eighty-four COVID-19 patients in MV were admitted in ICU. Ninety-four patients (33%) had VAP during the ICU stay, of which 85 had a single episode of VAP and 9 multiple episodes. The median time of onset of VAP from intubation were 8 days (IQR, 5–13). The overall incidence of VAP was of 13.48 episodes per 1000 days in MV. The main etiological agent was Pseudomonas aeruginosa (39.8% of all VAPs) followed by Klebsiella spp. (16.5%); of them, 41.4% and 17.6% were carbapenem resistant, respectively. Patients during the mechanical ventilation in orotracheal intubation (OTI) had a higher incidence than those in tracheostomy, 16.46 and 9.8 episodes per 1000-MV day, respectively. An increased risk of VAP was reported in patients receiving blood transfusion (OR 2.13, 95% CI 1.26–3.59, p = 0.005) or therapy with Tocilizumab/Sarilumab (OR 2.08, 95% CI 1.12–3.84, p = 0.02). The pronation and PaO2/FiO2 ratio at ICU admission were not significantly associated with the development of VAPs. Furthermore, VAP episodes did not increase the risk of death in ICU COVID-19 patients. Conclusions COVID-19 patients have a higher incidence of VAP compared to the general ICU population, but it is similar to that of ICU ARDS patients in the pre-COVID-19 period. Interleukin-6 inhibitors and blood transfusions may increase the risk of VAP. The widespread use of empirical antibiotics in these patients should be avoided to reduce the selecting pressure on the growth of multidrug-resistant bacteria by implementing infection control measures and antimicrobial stewardship programs even before ICU admission.

Abstract
Abstract
Study question
Is follicular viability of slow-frozen human ovarian tissue preserved if rapid thawing is performed using a solution containing extracellular cryoprotectant only?
Summary answer
Follicular viability is preserved even using thawing solutions containing extracellular cryoprotectant only, combining kits with different composition.
What is known already
Ovarian tissue cryopreservation is an alternative option to oocytes or embryos for fertility preservation in cancer patients facing gonadotoxic treatments. To date, each brand producing kits approved for the slow-freezing of human ovarian tissue recommends the use of its own thawing kit. However, a potential single protocol based on the use of any extracellular cryoprotectant has already been proposed for human oocytes and embryos. The current study aims at finding alternative options to thaw cryopreserved human ovarian tissue when the original kit was withdrawn from the market and only one CE-marked kit was available, even with different composition in cryoprotectants.
Study design, size, duration
Ovarian tissue cryopreservation of ten cancer patients (18.3 ± 7.6 years) undergoing fertility preservation between 2001 and 2012 was performed following a slow-freezing protocol with 1.5M 1,2 PROH and 0.5M Sucrose. Once deceased, for each patient, cortical fragments were prospectively thawed and equally allocated into two groups: i) fragments thawed using 0.5-1M 1,2 PROH and 0.3M Sucrose (PROH+S Group, n = 73); ii) fragments thawed following an adjusted protocol with 0.5M Sucrose only (S Group, n = 73).
Participants/materials, setting, methods
Post thawing follicular density/mm2, integrity (%) and the presence of interstitial oedema were assessed by histological and ultrastructural analysis performed after formalin fixation and haematoxylin/eosin staining. Follicular viability was evaluated by the expression of markers of proliferation (Ki67) and of vascularization (CD31) by immunohistochemistry after a 24h culture in Iscove’s modified Dulbecco’s medium at 37 °C and 6% CO2. A paired comparison was performed referring to the fresh tissue of the same patient as control.
Main results and the role of chance
The histological evaluation performed after thawing revealed that follicles were predominantly primordial (91%), with no follicles larger than the proliferating primary stage. A significant reduction of follicular density per mm2 was observed in both study groups (14.2 ± 12.0 vs. 15.1 ± 14.0 for PROH+S and S Group, respectively; p = 0.4) compared to the fresh tissue (27.2 ± 31.6; p = 0.04) as well as a remarkable decreased of the proportion of intact follicles (39.3 ± 17.1 vs. 25.5 ± 9.8; p = 0.2) compared to the fresh tissue (98.1 ± 1.4; p = 0.002). Thawed samples equally showed interstitial oedema and increased stromal cell vacuolization and chromatin clumping. Ki67 positive staining of active proliferating cells revealed a comparable proportion of viable follicles between thawed samples (46.3 ± 20.8 vs. 28.3 ± 27.9 for PROH+S and S Group, respectively; p = 0.2). Finally, the expression of the endothelial marker CD31 in the thawed samples suggested an equivalent number of blood vessels per mm2 (43.8 ± 34.3 vs. 41.7 ± 44.8; p = 0.6).
Limitations, reasons for caution
Single centre study with a limited sample size. Only 24h of in vitro culture was assessed. The use of the freezing medium corresponding to the Sucrose only solution was not tested. Clinical outcomes after ovarian tissue transplantation should be evaluated before drawing final conclusion.
Wider implications of the findings
First evidence of the feasible application of a “Universal Warming” protocol, irrespective of brand and cryoprotectants, for the rapid thawing of slow-frozen human ovarian tissue. IVF centres would be provided with alternative options to thaw ovarian tissue for restoring reproductive potential in cancer patient undergoing ovarian transplantation.

Effect of rLH Supplementation during Controlled Ovarian Stimulation for IVF: Evidence from a Retrospective Analysis of 1470 Poor/Suboptimal/Normal Responders Receiving Either rFSH plus rLH or rFSH Alone.

Abstract
We retrospectively studied a real-life population of 1470 women undergoing IVF, with poor/suboptimal/normal ovarian responsiveness to controlled ovarian stimulation (COS), comparing the cumulative live birth rate (cLBR) when COS was performed using rFSH alone or rFSH + rLH in a 2:1 ratio. Overall, we observed significantly higher cLBR in the rFSH alone group than in the rFSH + rLH group (29.3% vs. 22.2%, p < 0.01). However, considering only suboptimal/poor responders (n = 309), we observed comparable cLBR (15.6% vs. 15.2%, p = 0.95) despite the fact that patients receiving rFSH + rLH had significantly higher ages and worse ovarian reserve markers. The equivalent effectiveness of rFSH + rLH and rFSH alone was further confirmed after stratification according to the number of oocytes retrieved: despite basal characteristics were still in favor of rFSH alone group, the cLBR always resulted comparable. Even subdividing patients according to the POSEIDON classification, irrespective of differences in the baseline clinical characteristics in favor of FSH alone group, the cLBR resulted comparable in all subgroups. Despite the retrospective, real-life analysis, our data suggest that rLH supplementation in COS may represent a reasonable option for patients with predictable or unexpected poor/suboptimal ovarian responsiveness to FSH, those matching the Bologna criteria for poor responsiveness, and those included in the POSEIDON classification.

Abstract
PURPOSE To study whether a new combination of different warming kits is clinically effective for vitrified human blastocysts. METHODS This is a longitudinal cohort study analysing two hundred fifty-five blastocysts warming cycles performed between January and October 2018. Embryos were vitrified using only one brand of ready-to-use kits (Kitazato), whereas the warming procedure was performed with three of the most widely used vitrification/warming kits (Kitazato, Sage and Irvine) after patient stratification for oocyte source. The primary endpoint was survival rate, while the secondary endpoints were clinical pregnancy, live birth and miscarriage rates. RESULTS We observed a comparable survival rate across all groups of 100% (47/47) in KK, 97.6% (49/50) in KS, 97.6% (41/42) in KI, 100% (38/38) in dKK, 100% (35/35) in dKS and 100% (43/43) in dKI. Clinical pregnancy rates were also comparable: 38.3% (18/47) in KK, 49% (24/49) in KS, 56.1% (23/ 41) in KI, 47.4% (18/38) in dKK, 31.4% (11/35) in dKS and 48.8% (21/ 43) in dKI. Finally, live birth rates were 29.8% (14/47) in KK, 36.7% (18/49) in KS, 46.3% (19/41) in KI, 36.8% (14/38) in dKK, 25.7% (9/35) in dKS and 41.9% (18/43) in dKI, showing no significant differences. CONCLUSION This study confirmed the efficacy of applying a single warming protocol, despite what the "industry" has led us to believe, supporting the idea that it is time to proceed in the cryopreservation field and encouraging embryologists worldwide to come out and reveal that such a procedure is possible and safe.

Abstract
Background Limited data are available about the predictors and outcomes associated with prolonged SARS-CoV-2 RNA shedding (VS). Methods A retrospective study including COVID-19 patients admitted to an Italian hospital between March 1 and July 1, 2020. Predictors of viral clearance (VC) and prolonged VS from the upper respiratory tract were assessed by Poisson regression and logistic regression analyses. The causal relation between VS and clinical outcomes was evaluated through an inverse probability weighted Cox model. Results The study included 536 subjects. The median duration of VS from symptoms onset was 18 days. The estimated 30-day probability of VC was 70.2%. Patients with comorbidities, lymphopenia at hospital admission, or moderate/severe respiratory disease had a lower chance of VC. The development of moderate/severe respiratory failure, delayed hospital admission after symptoms onset, baseline comorbidities, or D-dimer >1000 ng/mL at admission independently predicted prolonged VS. The achievement of VC doubled the chance of clinical recovery and reduced the probability of death/mechanical ventilation. Conclusions Respiratory disease severity, comorbidities, delayed hospital admission and inflammatory markers negatively predicted VC, which resulted to be associated with better clinical outcomes. These findings highlight the importance of prompt hospitalization of symptomatic patients, especially where signs of severity or comorbidities are present.

Abstract
Background and Objectives: Some biomarkers of ovarian responsiveness to gonadotropins and the total number of retrieved oocytes are known to affect the success rate after controlled ovarian stimulation (COS) and in vitro fertilization (IVF). The aim of this study was to study another putative marker, the Ovarian Sensitivity Index (OSI: (number of retrieved oocytes/total gonadotropin dose) × 1000), assessing whether (a) it correlates with ovarian responsiveness biomarkers, (b) it is an independent predictor of clinical pregnancy, (c) it predicts clinical pregnancy comparably to the number of retrieved oocytes, and (d) it is consistent in the repeated COS cycles of the same woman. Design: retrospective analysis. Setting: public IVF Unit in University Hospital. Cases and Measurements: 1612 patients submitted to 3353 IVF cycles were included, their OSI was calculated and it was correlated with the ovarian responsiveness biomarkers (age, BMI, anti-Mullerian hormone, antral follicle count). The OSI and the total number of oocytes were compared for their value in predicting clinical pregnancy. The inter-cycle consistency of the OSI was estimated in 209 patients who underwent two consecutive cycles in which the ovarian stimulation regimen was changed from the Gonadotropin-releasing Hormone (GnRH)-agonist long protocol to the GnRH-antagonist protocol or vice-versa. Results: The OSI turned out to be significantly related to age and BMI (inversely), the anti-Mullerian hormone (AMH) and the antral follicle count (AFC) (directly), to be an independent predictor of clinical pregnancy, and to correlate with clinical pregnancy better than the total number of oocytes (p < 0.0001 vs. <0.002). In patients who underwent two consecutive COS cycles changing stimulation regimen, the OSI showed 82% consistency. Conclusion(s): The OSI significantly correlates to the currently used biomarkers of ovarian responsiveness; it is an independent predictor of clinical pregnancy; it is more predictive of clinical pregnancy than the total number of oocytes, and is highly consistent in repeated IVF cycles even when the COS protocol changes. These characteristics make the OSI quite suitable to be incorporated into more complex prediction models of IVF outcome.

Abstract
BACKGROUND The complex relationship between oocyte morphology, specific follicular fluid metabolites, gene expression in cumulus granulosa cells, and oocyte competence toward fertilization and embryo development still needs further clarification. METHODS Forty-six oocytes retrieved from the largest pre-ovulatory follicle of patients undergoing intra-cytoplasmic sperm injection (ICSI) were considered assessing: (a) oocyte morphological characteristics at polarized light microscopy (PLM), (b) specific follicular fluid (FF) metabolites previously suggested to influence oocyte competence (AMH, markers of redox status and of cytotoxicity), (c) transcription of AMH and AMH type II receptor genes in cumulus cells. Data were analyzed using mono-parametric tests and multivariable logistic analysis in order to correlate morphological and biochemical data with fertilization. RESULTS Comparing normally fertilized oocytes (n = 29, F group) with unfertilized (n = 17, nF group) we observed that: (a) the meiotic spindle area and major axis were significantly higher in nF group and in fertilized oocytes undergoing an early embryo development arrest; (b) AMH level in FF was comparable in F and nF groups; (c) the FF of nF group contained significantly higher levels of cytotoxicity (lactate dehydrogenase) and oxidative stress (Cu,Zn-superoxide dismutase, catalase, 4-hydroxynonenal-protein conjugates) markers; (d) cumulus cells of nF group showed significantly higher AMH receptor type II gene expression. CONCLUSIONS Taken together, these observations suggest that an excessive cytotoxicity level can alter AMH signal transduction within cumulus cells, in turn leading to partial inhibition of aromatase activity, altered cytoplasmic maturation and increased oxidative stress, factors able to impair oocyte fertilization competence and embryo growth.

Abstract
The purpose of this study was to observe in vitro-matured equine oocytes with an objective computerized technique that involves the use of a polarized light microscope (PLM) in addition to the subjective morphological evaluation obtained using a classic light microscope (LM). Equine cumulus-oocyte complexes (COCs, n = 922) were subjected to different in vitro maturation times (24, 36 or 45 h), however, only 36-h matured oocytes were analyzed using CLM. The 36-h matured oocytes that reached maturity were parthenogenetically activated to evaluate the quality and meiotic competence. Average maturation percentages per session in groups 1, 2 and 3 (24-, 36- and 45-h matured oocytes respectively) were 29.31 ± 13.85, 47.01 ± 9.90 and 36.62 ± 5.28%, whereas the average percentages of immature oocytes per session were 28.78 ± 20.17, 7.83 ± 5.51 and 22.36 ± 8.39% respectively. The zona pellucida (ZP) birefringent properties were estimated and correlated with activation outcome. ZP thickness and retardance of the inner layer of the zona pellucida (IL-ZP) were significantly increased in immature oocytes compared with mature oocytes (P < 0.001 and P < 0.01 respectively). The comparison between parthenogenetically activated and non-activated oocytes showed a significant increase in the area and thickness of the IL-ZP in parthenogenetically activated oocytes (P < 0.01). These results show that the 36-h in vitro maturation (IVM) protocol allowed equine oocytes to reach maturity, and PLM observation of ZP can be used to distinguish mature and immature oocytes as well as activated and non-activated oocytes.

Abstract
According to enhanced long-term survival rates of these patients, interest in fertility preservation for young women facing gonadotoxic therapies is increasing. Women who carry a mutation in the BRCA1 or BRCA2 gene have a specifically increased lifetime risk of developing breast and tubo-ovarian cancer. Moreover, they are at high risk of undergoing premature infertility due to the medical interventions that are often performed in order to reduce cancer risk or treat an already existing malignancy. Fertility issues are relevant for healthy BRCA mutation carriers, whose family-planning decisions are often influenced by the need of prophylactic bilateral salpingo-oophorectomy at young age. In BRCA mutation carriers who have a breast cancer at young age, the oncostatic treatment is associated with a significant ovarian toxicity linked to chemotherapy as well as to the long lasting hormonotherapy and to the need of delaying pregnancy for several years. Prompt counselling about different fertility preservation options should be offered to all young girls and women at high risk of ovarian insufficiency and infertility. Validated techniques to preserve fertility include oocyte and embryo cryopreservation, while experimental techniques include ovarian suppression with GnRH-analogs during chemotherapy and ovarian tissue cryopreservation. The choice of the best strategy depends on age, type of chemotherapy, partner status, cancer type, time available for fertility preservation intervention and the risk of ovarian metastasis. All available options should be offered and can be performed alone or in combination. A crucial point is to avoid a significant delay to cancer treatment.

Abstract
OBJECTIVE To compare in a randomized, non-inferiority trial the embryo transfer (ET) technique based on uterine length measurement before transfer (ULMbET) with transabdominal ultrasound-guided embryo transfer (TA-UGET) in a large population of patients undergoing in-vitro fertilization (IVF). METHODS Patients undergoing IVF with ET with cleaving fresh embryos were randomized to receive ULMbET or TA-UGET. The transfer of one to three embryos on day 2-3 of culture was performed using a soft catheter either under transabdominal ultrasound guidance (TA-UGET group) or after measurement of the uterine cavity by transvaginal ultrasound and calculation of the discharge site (ULMbET group). The primary outcome measures were clinical pregnancy rate, ongoing pregnancy rate and implantation rate, and secondary outcomes included patient discomfort during ET. RESULTS A total of 1648 patients undergoing IVF were randomized to receive ULMbET (n = 828) or TA-UGET (n = 820) and were included in the analysis. Comparable clinical pregnancy rate (38.2% vs 38.9%), implantation rate (24.8% vs 25.2%) and ongoing pregnancy rate (33.1% vs 34.8%) were observed in ULMbET and TA-UGET groups. The discomfort intensity score and the proportion of patients with moderate-to-severe discomfort during ET were significantly higher in the TA-UGET group (2.6 vs 1.5 visual analog scale points and 19.8% vs 1.2%; P = 0.045 and P = 0.003, respectively). CONCLUSION The ULMbET technique leads to IVF results comparable to those obtained with UGET, but is better tolerated than is TA-UGET and is technically easier to perform for a single operator.

Abstract
BACKGROUND This large prospective, randomized study was designed to compare the "mild" protocol with clomiphene citrate, low-dose gonadotropins and a GnRH-antagonist (CC/Gn/GnRH-ant protocol) with the "long" protocol with a GnRH-agonist and high-dose Gn for the controlled ovarian hyperstimulation (COH) of patients with expected poor ovarian responsiveness undergoing IVF. MATERIALS AND METHODS A total of 695 women with clinical, endocrine and ultrasound characteristics suggesting a low ovarian reserve and a poor responsiveness to COH were recruited and randomly assigned to receive the CC/Gn/GnRH-ant "mild" protocol (mild group, n = 355) or the "long" protocol with high-dose Gn (long group, n = 340). RESULTS The "mild" stimulation led to significantly shorter follicular phase, lower consumption of exogenous Gn and lower peak estradiol level than the "long" regimen. With the "long" protocol, significantly less cycles were cancelled due to the lack of ovarian response; further, it obtained significantly more oocytes, more mature oocytes, more embryos, and a thicker endometrium. As for the final IVF outcome, however, the two stimulation regimens obtained comparable implantation rate, clinical pregnancy rate, and ongoing pregnancy rate at 12 weeks. CONCLUSIONS In conclusion, the "mild" CC/Gn/GnRH-ant stimulation protocol is a valid alternative to the long protocol with high Gn dose as it obtains a comparable success rate and requires significantly less medications, with an obvious economical advantage.

Abstract
The interplay between oocyte and surrounding cumulus cells (CCs) during follicular growth influences oocyte competence to undergo fertilization and sustain embryo development. The expression of many genes and proteins in CCs has been suggested as potential biomarker of oocyte competence in human in vitro fertilization (IVF). In the present study, we analyzed 90 human cumulus-oocyte complexes obtained during IVF procedure: 30 CCs were analyzed using quantitative real-time polymerase chain reaction and 60 CCs using Western blotting analysis to detect gene and protein expression of some enzymes related to oxidative stress, that is, the 3 nitric oxide synthase (NOS) isoforms and heme oxygenase 1 (HO-1). In the group of 60 CCs, we also investigated the expression and phosphorylation of IkBα, a known inhibitor of the nuclear factor κB (NF-κB) pathway, which controls several redox-sensitive genes. The expression of the messenger RNAs (mRNAs) was related to the oocyte morphological analysis performed by polarized light microscopy and to the occurrence of normal fertilization after intracytoplasmic sperm injection. We observed that the amount of iNOS and HO-1 mRNAs and proteins is significantly higher, and that in the meanwhile the NF-κB pathway is activated, in CCs corresponding to oocytes that were not fertilized in comparison to CCs whose corresponding oocyte showed normal fertilization. Instead, no correlation between the fertilization and the oocytes' morphological data was observed. These results suggest that the increase in iNOS and HO-1 mRNAs expression in CCs is a negative index of oocyte fertilizability and might be an useful tool for oocyte selection.

Abstract
This communication reports a novel technical solution for the orthotopic transplant of cryostored-thawed ovarian tissue. The described technique was applied to three young women with iatrogenic ovarian failure. An echogenic thread that is reabsorbed after 6 months was used to fasten the thawed ovarian small fragments before grafting them onto the atrophic ovary. This technical solution made it possible to avoid the loss of small tissue pieces during laparoscopic grafting as well as to precisely localize the grafted tissue by transvaginal ultrasound during the following months. The precise localization of the grafted tissue was particularly helpful when its revascularization and functional recovery were followed up using, respectively, colour Doppler and transvaginal follicle growth examination. In conclusion, the use of a slowly reabsorbed, ultrasound-detectable surgical thread as an ultrasound-detectable marker able to improve the localization of the exact site at which ovarian tissue was grafted is proposed.

Abstract
Every day patients on peritoneal dialysis (PD) must focus on their dialysis schedules and on nutritional and therapeutic prescriptions. Unfortunately, over time all these actions may not follow the initial protocol. In order to evaluate patient's knowledge and approach to dialysis, an alternative educational tool to hospital or home was investigated. The campus was utilised as a place for re-training and detecting and correcting discrepancies in knowledge and the management of techniques. A continuous educational programme involves some re-training of PD patients and this approach helps us to identify whether the treatment management at home is in accordance with the information given at the start of the dialysis, but there was a need to improve on this and to improve patient understanding and compliance. The campus was chosen as an alternative educational process with the aim of involving the patients themselves and their families to achieve additional benefits and long-term success of the therapy. This initiative, outside the hospital and in collaboration with professional figures not affiliated with the dialysis unit, hoped to offer patients new knowledge about: dialysis technique and procedures, prevention of infectious complications, nutrition and physical activity.

Abstract
The impact of hypertension on vascular structure at different arterial sites and the relation of vascular hypertrophy with left ventricular (LV) hypertrophy in the early stages of essential hypertension are unclear. In 96 newly diagnosed, never-treated, uncomplicated hypertensive subjects aged < 55 years (43 +/- 9 years, 68 men, clinic blood pressure 152/99 mm Hg, 24-h blood pressure 135/89 mm Hg), we measured LV mass (M-mode echocardiography) and intima-media thickness (IMT) of the carotid and femoral arteries (high-resolution B-mode ultrasound). The average of 24 carotid and 24 femoral IMT readings (common and internal carotid or common and superficial femoral, right and left side, far and near wall, three sampling points per segment) was analyzed. Carotid and femoral IMT were strongly related to each other (r = 0.77). Subjects with LV hypertrophy (n = 33) had a greater IMT at the carotid (0.84 +/- 0.2 v 0.71 +/- 0.2 mm, P < .0001) and femoral (0.77 +/- 0.1 v 0.64 +/- 0.1 mm, P < .0001) level. Carotid IMT showed a positive correlation with LV mass (r = 0.46) and age (r = 0.38), and an inverse one with high-density lipoprotein (HDL) cholesterol (r = -0.26). Femoral IMT was associated positively to LV mass (r = 0.50), age (r = 0.33) and triglycerides (r = 0.29), and inversely to HDL-cholesterol (r = -0.33). The association between IMT (both carotid and femoral) and LV mass held after controlling for age and other confounders in a multiple regression analysis. In summary, in the early stages of hypertension arterial wall thickening appears to be a diffuse process, which occurs in parallel at the carotid and femoral level and shows a positive association with LV hypertrophy.

Abstract
Recent reports of changes in the epidemiology of syphilis prompted a review of syphilis in our urban community. All records of positive syphilis serology reported to the City of Scarborough Health Department between 1990-94 were reviewed for key epidemiological variables. While infectious stages of syphilis were reported more often among young adults, incidence for all stages increased among successive age groups, with a male/female ratio of 1.0. One in five cases were identified during immigration screening, with a disproportionate number of cases immigrating from the Caribbean, Africa and Subcontinental India. Overall, the incidence of syphilis decreased during the study. However, a correlation of 0.95 was found between the provincial incidence of syphilis and number of tests ordered. The observed decrease in syphilis, therefore, may represent a decrease in detection owing to lack of testing.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare tumor of the pancreaticobiliary region. The etiology and biologic behavior of IMTs at this site are unknown. We present three patients with IMT of the pancreaticobiliary region, each with long-term follow-up. In all three cases a second tumor developed. Grossly these tumors mimicked a malignant process. Microscopically, all were composed of an admixture of spindle cells and chronic inflammatory cells, including plasma cells, lymphocytes, eosinophils, and macrophages. The spindle cells stained positively for smooth muscle actin and vimentin but were negative for S-100, cytokeratin, CD35, and latent membrane protein. Results of in situ hybridization with EBER probes were negative in all cases. In addition to carcinoma, the differential diagnosis of these tumors includes follicular dendritic cell tumor and inflammatory fibrosarcoma. The importance of extensive pathologic examination to prevent misdiagnosis and the need for long-term follow-up are emphasized. This subset of IMT does not appear to be related to Epstein-Barr virus.
