Abstract
BACKGROUND The contribution of artefenomel to the clinical and parasiticidal activity of ferroquine and artefenomel in combination in uncomplicated Plasmodium falciparum malaria was investigated. METHODS This Phase 2a, randomized, open-label, parallel-group study was conducted from 11th September 2018 to 6th November 2019 across seven centres in Benin, Burkina Faso, Gabon, Kenya, and Uganda. Patients aged ≥ 14-69 years with microscopically confirmed infection (≥ 3000 to ≤ 50,000 parasites/µL blood) were randomized 1:1:1:1 to 400 mg ferroquine, or 400 mg ferroquine plus artefenomel 300, 600, or 1000 mg, administered as a single oral dose. The primary efficacy analysis was a logistic regression evaluating the contribution of artefenomel exposure to Day 28 PCR-adjusted adequate clinical and parasitological response (ACPR). Safety was also evaluated. RESULTS The randomized population included 140 patients. For the primary analysis in the pharmacokinetic/pharmacodynamic efficacy population (N = 121), the contribution of artefenomel AUC0-∞ to Day 28 PCR-adjusted ACPR was not demonstrated when accounting for ferroquine AUC0-d28, baseline parasitaemia, and other model covariates: odds ratio 1.1 (95% CI 0.98, 1.2; P = 0.245). In the per-protocol population, Day 28 PCR-adjusted ACPR was 80.8% (21/26; 95% CI 60.6, 93.4) with ferroquine alone and 90.3% (28/31; 95% CI 74.2, 98.0), 90.9% (30/33; 95% CI 75.7, 98.1) and 87.1% (27/31; 95% CI 70.2, 96.4) with 300, 600, and 1000 mg artefenomel, respectively. Median time to parasite clearance (Kaplan-Meier) was 56.1 h with ferroquine, more rapid with artefenomel, but similar for all doses (30.0 h). There were no deaths. Adverse events (AEs) of any cause occurred in 51.4% (18/35) of patients with ferroquine 400 mg alone, and 58.3% (21/36), 66.7% (24/36), and 72.7% (24/33) with 300, 600, and 1000 mg artefenomel, respectively. All AEs were of mild-to-moderate severity, and consistent with the known profiles of the compounds. Vomiting was the most reported AE. There were no cases of QTcF prolongation ≥ 500 ms or > 60 ms from baseline. CONCLUSION The contribution of artefenomel exposure to the clinical and parasitological activity of ferroquine/artefenomel could not be demonstrated in this study. Parasite clearance was faster with ferroquine/artefenomel versus ferroquine alone. All treatments were well tolerated. TRIAL REGISTRATION ClinicalTrials.gov, NCT03660839 (7 September, 2018).

Abstract
Culicoides Latreille (Diptera: Ceratopogonidae) transmit arboviruses affecting wild and domestic ruminants such as bluetongue (BTV) and Schmallenberg virus (SBV). The sub-adult development and lifespan of Culicoides obsoletus s.s. (Meigen), Culicoides circumscriptus Kieffer and Culicoides paolae Boorman were examined at three different temperatures under laboratory conditions. Insects were collected from field between spring and autumn 2015 in two livestock farms located in Majorca (Spain). Gravid females were held individually at 18, 25 or 30 °C. Low temperatures increased the adult lifespan, time to oviposit and rate of development, whereas high temperatures increased the number of eggs, successful pupation and adult emergence as well as the larvae growth rate. The results showed that C. obsoletus s.s. have optimum development at 18 °C, whereas the optimal rearing temperature for C. circumscriptus and C. paolae was under warmer conditions of 25-30 °C. Variations in temperature/humidity and assays with different materials and substrates for oviposition should be considered in future studies. Understanding the requirements of the different species of Culicoides optimizing the results should be of special interest for predicting environmental change effects on these species, in addition to determining the rearing conditions for candidate Culicoides vectors.

Abstract
BACKGROUND In human immunodeficiency virus (HIV), the relative contribution of genetic background, clinical risk factors, and antiretrovirals to chronic kidney disease (CKD) is unknown. METHODS We applied a case-control design and performed genome-wide genotyping in white Swiss HIV Cohort participants with normal baseline estimated glomerular filtration rate (eGFR >90 mL/minute/1.73 m2). Univariable and multivariable CKD odds ratios (ORs) were calculated based on the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) score, which summarizes clinical CKD risk factors, and a polygenic risk score that summarizes genetic information from 86 613 single-nucleotide polymorphisms. RESULTS We included 743 cases with confirmed eGFR drop to <60 mL/minute/1.73 m2 (n = 144) or ≥25% eGFR drop to <90 mL/minute/1.73 m2 (n = 599), and 322 controls (eGFR drop <15%). Polygenic risk score and D:A:D score contributed to CKD. In multivariable analysis, CKD ORs were 2.13 (95% confidence interval [CI], 1.55-2.97) in participants in the fourth (most unfavorable) vs first (most favorable) genetic score quartile; 1.94 (95% CI, 1.37-2.65) in the fourth vs first D:A:D score quartile; and 2.98 (95% CI, 2.02-4.66), 1.70 (95% CI, 1.29-2.29), and 1.83 (95% CI, 1.45-2.40), per 5 years of exposure to atazanavir/ritonavir, lopinavir/ritonavir, and tenofovir disoproxil fumarate, respectively. Participants in the first genetic score quartile had no increased CKD risk, even if they were in the fourth D:A:D score quartile. CONCLUSIONS Genetic score increased CKD risk similar to clinical D:A:D score and potentially nephrotoxic antiretrovirals. Irrespective of D:A:D score, individuals with the most favorable genetic background may be protected against CKD.

Abstract
Changes in environmental conditions, whether related or not to human activities, are continuously modifying the geographic distribution of vectors, which in turn affects the dynamics and distribution of vector-borne infectious diseases. Determining the main ecological drivers of vector distribution and how predicted changes in these drivers may alter their future distributions is therefore of major importance. However, the drivers of vector populations are largely specific to each vector species and region. Here, we identify the most important human-activity-related and bioclimatic predictors affecting the current distribution and habitat suitability of the mosquito Culex pipiens and potential future changes in its distribution in Spain. We determined the niche of occurrence (NOO) of the species, which considers only those areas lying within the range of suitable environmental conditions using presence data. Although almost ubiquitous, the distribution of Cx. pipiens is mostly explained by elevation and the degree of urbanization but also, to a lesser extent, by mean temperatures during the wettest season and temperature seasonality. The combination of these predictors highlights the existence of a heterogeneous pattern of habitat suitability, with most suitable areas located in the southern and northeastern coastal areas of Spain, and unsuitable areas located at higher altitude and in colder regions. Future climatic predictions indicate a net decrease in distribution of up to 29.55%, probably due to warming and greater temperature oscillations. Despite these predicted changes in vector distribution, their effects on the incidence of infectious diseases are, however, difficult to forecast since different processes such as local adaptation to temperature, vector-pathogen interactions, and human-derived changes in landscape may play important roles in shaping the future dynamics of pathogen transmission.

Abstract
Objective There is limited data on abdominal obesity and the influence of genetics on weight change after antiretroviral therapy (ART) initiation. We assessed body mass index (BMI) and waist hip ration (WHR) change over time in the Swiss HIV Cohort study (SHCS). Methods Mixed-effects models characterizing BMI and WHR change over time in 1090 SHCS participants initiating ART between 2005 and 2015 were developed and used to quantify the influence of demographics, clinical factors, and genetic background. Results Individuals with CD4 nadir <100 cells/µL gained 6.4 times more BMI than individuals with ≥200, and 2.8 times more WHR than individuals with ≥100 (P < .001) during the first 1.5 and 2.5 years after ART initiation, respectively. The risk of being overweight or obese after 1.5 years increased with CD4 nadir <100 cells/µL compared to 100–199 (odds ratio [OR], 2.07; 95% confidence interval [CI], 1.63–2.74) and ≥200 (OR, 1.69; 95% CI, 1.26–2.32), persisting after 10 years of ART. The risk of abdominal obesity after 2.5 years increased with CD4 nadir <100 compared to ≥100 (OR, 1.35; 95% CI, 1.17–1.54 [in men]; OR, 1.36; 95% CI, 1.18–1.57 [in women]), persisting after 10 years of ART. No significant differences were found across antiretroviral drug classes or genetic scores. Conclusions The risk of general and abdominal obesity increased with CD4 nadir <100 cells/µL. Based on our results, including the genetic background would not improve obesity predictions in HIV-infected individuals.

Abstract
The Asian tiger mosquito, Aedes albopictus (Diptera: Culicidae), is a highly invasive species and a vector of several viruses of serious concern to public health. Investigating the habitat selection of this species at small to medium scales is essential to the planning of effective prevention and control campaigns. The present group considered detailed data for this species' presence/absence collected at 228 sites on Mallorca Island (Spain) in autumn 2015, 3 years after the first detection of the species on the island. Site occupancy models accounting for false negative detections and imperfect monitoring were used to evaluate the relationships between mosquito presence and habitat variables. In the study area, mosquito presence was negatively associated with altitude, probably as a result of greater human presence at low altitudes near the coast. Moreover, the presence of Ae. albopictus was positively associated with swimming pools as a result of associated gardens, plants and sources of fresh water. These two variables were combined to predict the presence of the species across the entire island.

Abstract
This research contributes to knowledge of the basic bionomic parameters of vector and non-vector Culicoides species. Field-collected gravid C. imicola and Obsoletus complex showed the longest lifespans in laboratory conditions. Culicoides paolae and C. circumscriptus seemed to be the most suitable species for laboratory rearing in view of their high oviposition rates, short lifecycles, long adult lifespans and female-biased sex ratios.

Abstract
OBJECTIVE Short-term prediction of pre-eclampsia (PE) using the soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratio is characterized by frequent false-positive results. As such, no treatment can be recommended to test-positive patients and multiple measurements are often required. The aim of this study was to evaluate the effectiveness of N-terminal pro-B natriuretic peptide (NT-proBNP), uric acid and the sFlt-1/PlGF ratio for prediction of delivery with PE within 1 week in singleton pregnancies with suspected PE and sFlt-1/PlGF ratio > 38. METHODS This was a longitudinal prospective cohort study of singleton pregnancies presenting at 24 + 0 to 36 + 6 weeks of gestation with clinically suspected PE and sFlt-1/PlGF ratio > 38, enrolled between January 2015 and June 2017. Multiple samples per patient were allowed but were restricted to one sample per gestational week. From 495 enrolled patients, 270 blood samples from 134 patients were ultimately analyzed. By using generalized estimating equations (GEE), the best-fit model was selected for prediction of delivery with PE within 1 week. The predictive value of this model was then assessed using area under the paired-ROC curve (AUC) analysis. RESULTS The best-fit model included the sFlt-1/PlGF ratio, NT-proBNP and the gestational week at the time of the measurement. This combined model was compared with the GEE model based on the sFlt-1/PlGF ratio and the gestational week at the time of the measurement (reduced model). The AUC for the combined model was 0.845 (95% CI, 0.787-0.896), which was significantly greater (P = 0.011) than that of the reduced model (0.786 (95% CI, 0.722-0.844)). CONCLUSION The addition of NT-proBNP assessment improves the short-term prediction of delivery as a result of PE compared with sFlt-1/PlGF ratio alone, when the sFlt-1/PlGF ratio is > 38. This finding should be considered in future research on the assessment of short-term risk of delivery as a result of PE. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND Cutaneous malignant melanoma arises from transformed melanocytes de novo or from congenital or acquired melanocytic naevi. We have recently reported that T-type Ca2+ channels (TT-Cs) are upregulated in human melanoma and play an important role in cell proliferation. OBJECTIVES To describe for the first time in formalin-fixed paraffin-embedded tissue the immunoexpression of TT-Cs in biopsies of normal skin, acquired melanocytic naevi and melanoma, in order to evaluate their role in melanomagenesis and/or tumour progression, their utility as prognostic markers and their possible use in targeted therapies. METHODS Tissue samples from normal skin, melanocytic naevi and melanoma were subjected to immunohistochemistry for two TT-Cs (Cav3.1, Cav3.2); markers of proliferation (Ki67), the cell cycle (cyclin D1), hypoxia (Glut1), vascularization (CD31) and autophagy (LC3); BRAF V600E mutation (VE1) and phosphatase and tensin homologue (PTEN). Immunostaining was evaluated by histoscore. In silico analysis was used to assess the prognostic value of TT-C overexpression. RESULTS TT-C immunoexpression increased gradually from normal skin to common naevi, dysplastic naevi and melanoma samples, but with differences in the distribution of both isoforms. Particularly, Cav3.2 expression was significantly higher in metastatic melanoma than in primary melanoma. Statistical correlation showed a linear interaction between PTEN loss/BRAF V600E/Cav3.1/LC3/ Ki67/cyclin D1/Cav3.2/Glut1. Disease-free survival (DFS) and overall survival correlated inversely with overexpression of Cav3.2. DFS also correlated inversely with overexpression of Cav3.1. CONCLUSIONS TT-C immunoexpression on melanocytic neoplasms is consistent with our previous in vitro studies and appears to be related to tumour progression. TT-C upregulation can be considered as a prognostic marker using The Cancer Genome Atlas database. The high expression of Cav3.2 in metastatic melanoma encourages the investigation of the use of TT-C blockers in targeted therapies.

Abstract
Background. The impact of human genetic background on low-trauma fracture (LTF) risk has not been evaluated in the context of human immunodeficiency virus (HIV) and clinical LTF risk factors. Methods. In the general population, 6 common single-nucleotide polymorphisms (SNPs) associate with LTF through genome-wide association study. Using genome-wide SNP arrays and imputation, we genotyped these SNPs in HIV-positive, white Swiss HIV Cohort Study participants. We included 103 individuals with a first, physician-validated LTF and 206 controls matched on gender, whose duration of observation and whose antiretroviral therapy start dates were similar using incidence density sampling. Analyses of nongenetic LTF risk factors were based on 158 cases and 788 controls. Results. A genetic risk score built from the 6 LTF-associated SNPs did not associate with LTF risk, in both models including and not including parental hip fracture history. The contribution of clinical LTF risk factors was limited in our dataset. Conclusions. Genetic LTF markers with a modest effect size in the general population do not improve fracture prediction in persons with HIV, in whom clinical LTF risk factors are prevalent in both cases and controls.

Abstract
OBJECTIVES Co-formulated elvitegravir, cobicistat, tenofovir disoproxil fumarate and emtricitabine is among the preferred regimens for first-line ART. A population approach was used to characterize the pharmacokinetics of elvitegravir and cobicistat and identify individual factors and co-medications influencing their disposition, taking into consideration the interaction between the two compounds. METHODS The study population included 144 HIV-infected individuals who provided 186 and 167 elvitegravir and cobicistat plasma concentrations, respectively. First, distinct NONMEM(®) analyses were conducted for elvitegravir and cobicistat, including individual demographic, clinical and genetic factors as potential covariates. Elvitegravir and cobicistat interaction was then assessed through different inhibitory models. Simulations based on the final model served to compare expected drug concentrations under standard and alternative dosage regimens. RESULTS Clearance with between-subject variability was 7.6 L/h [coefficient of variation (CV) 16.6%] and volume of distribution 61 L for elvitegravir and 16.0 L/h (CV 41.9%) and 88.3 L, respectively, for cobicistat. Concomitant administration of non-ritonavir-boosted atazanavir decreased elvitegravir clearance by 35%, likely due to UDP-glucuronosyl transferase (UGT) 1A1 inhibition. Concomitant administration of non-ritonavir-boosted atazanavir and ritonavir-boosted darunavir decreased cobicistat clearance by 47% and 27%, respectively. The final interaction model included cobicistat exposure (AUC0-24) on elvitegravir clearance. Simulations confirmed that a reduced elvitegravir dose of 85 mg co-administered with cobicistat and atazanavir produces a concentration-time course comparable to the standard regimen without atazanavir. CONCLUSIONS Elvitegravir and cobicistat pharmacokinetic variability appears to be mainly explained by drug-drug interactions that may be encountered in routine clinical practice. In these cases, therapeutic drug monitoring and surveillance for potential toxicities would be justified.

Abstract
UNLABELLED The current diagnosis of prostate cancer is based on randomized prostate biopsies to obtain histological material for study, without introducing any imaging technique in the diagnostic algorithm. OBJECTIVES To conduct a literature review of the role of multiparametric MRI ( mMRI ) in the diagnosis of prostate cancer, and present preliminary data from our series of 233 patients undergoing mRMN and transrectal ultrasound (TRUS) prostate biopsy. MATERIAL AND METHODS We performed a PubMed search for those articles that refer to the usefulness of mMRI in the follow-up and monitoring of patients with persistently elevated PSA without previous biopsies, and those with a previous negative biopsy, and assess the power of mRMN for detecting PCa in both the peripheral and the central gland. We present the preliminary results of our series, consisting of 233 patients selected between 2008 and 2011 undergoing mMRI and TRUS-guided prostatic biopsy because of elevated PSA levels or suspicious digital rectal examination. RESULTS We discuss several articles published from 2003 to 2014. We compare our results with those from the literature. DISCUSSION The diagnostic algorithm of prostate cancer to date does not include any imaging technique in the decision-making process. The mMRI is a functional imaging technique that provides increasing evidence in deciding which patients should be biopsied and which patients may avoid it despite persisting high levels of PSA. The advantage of this technique lies not only in its high detection rate in intermediate and high risk lesions, but also in its high specificity. It allows us to avoid diagnosing clinically insignificant tumors and thus, avoids overtreatment. CONCLUSION The mRMN is a useful technique not yet incorporated in algorithms of prostate cancer diagnosis in urological societies. Its safety, effectiveness and efficiency are forcing to include its progressive use and with high probability will be soon incorporated into the decision-making charts.

Abstract
Culicoides Latreille (Diptera: Ceratopogonidae) are vectors of several arboviruses, including bluetongue virus (BTV) and African horse sickness virus (AHSV), which cause diseases in, respectively, sheep and cattle, and horses, and have economic repercussions mainly as a result of trade restrictions. Insecticides can be used to reduce vector populations and hence the spread of disease. Despite the economic importance of these diseases, relatively few studies have evaluated the efficacy of commercially available insecticides and the effectiveness of treated nets against Culicoides species. The aim of the present study was to evaluate the insecticidal effect of commercially available polyethylene nets (ZeroVector(®) ) treated with deltamethrin (4.4 g/kg ± 15%) on Culicoides species. Laboratory and field trials were conducted in Culicoides populations collected in Majorca in the Balearic Islands, Spain. The present study shows that deltamethrin-treated nets provoke high and rapid mortality (90-100%) in Culicoides midges under laboratory conditions and increase mortality by 13% when deployed in the field.

Abstract
OBJECTIVE There is no consensus regarding the ideal treatment of loculated parapneumonic empyema (PPE). The aim of this study is to compare the effectiveness of drainage plus urokinase (DF) with video-assisted thoracoscopy (VATS). MATERIAL AND METHODS Retrospective review. Patients admitted with a PPE between January 2001 and July 2008. Loculated empyema was diagnosed by chest ultrasound and patients were treated with DF or VATS depending on the attending surgeon. Compared variables were: post-operative stay, total hospital stay, days of tube thoracostomy, post-operative fever and treatment failure. RESULTS One hundred and twenty one patients were admitted with the diagnosis of PPE. Seventeen patients were excluded from analysis because of simple parapneumonic effusions. Of the 104 patients included in the study, 47 were treated with urokinase and 57 with videothoracoscopy. No statistically significant differences (P>.05) were found between the median values in the DF and VATS groups for hospital stay (median 12 vs 12 days) or post-operative stay (median 9 vs 9 days). There were differences in duration of tube thoracostomy (median DF group 5 days, VATS, 4 days, P<.05) and in the post-operative fever (median 3 vs 2 days, p<0,05).Twenty two per cent of children needed a second procedure (14 patients of DF and 9 of VATS group, P=.09). CONCLUSIONS According to our experience, the results of DF and VATS for the treatment of loculated parapneumonic empyema are similar. Although there are no statistical differences, there seems to be a higher rate of failure, with the need of more procedures in the DF group. This difference does not affect the average total hospital stay.

Abstract
Primary lung tumours are uncommon in childhood. Among these tumours, endobronchial masses are even less common and, among benign tumours, inflammatory pseudotumours and hamartomas have the highest incidence in children. We present the case of a 2.5-year-old girl with a left endobronchial chondromesenchymal hamartoma with obstruction of 90% of the bronchial lumen. Complete resection of the endobronchial mass was performed by rigid bronchoscopy and application of topical mitomycin C. After tumour resection and a 12-month follow-up, the patient has shown a favourable outcome with immediate disappearance of respiratory symptoms. Successive fibreoptic bronchoscopies have shown no residual tumour.

Abstract
INTRODUCTION The traditional management of pediatric penetrating trauma has been wide surgical examination. However, the selective nonoperative management is increasing thanks to the precise diagnosis obtained from radiologic studies as CT scan. The purpose of this study is reviewing our experience in the last eight years with a less invasive management. PATIENTS AND METHODS We retrospectively reviewed (2000-2007) the patients with penetrating injuries of different parts of the body (excluding cranioencephalic traumatism) treated in our center and registered by the Clinical Documentation Unit. The variables collected and evaluated included age, mechanism of injury, kind of injury, diagnostic and therapeutic modalities and outcome. RESULTS There were 17 patients (median 9.5 years, range 4-17) with penetrating trauma. According the localization of injury the patients were divided into 4 groups: abdominal (17.6%), thoracic (23.5%), cervical (17.6%) and extremities (41.2%). The most frequent kind of injuries were: skin and muscle (with or without penetrating peritoneal or chest cavity, 52.9%) vascular or neurological structures (29.4%). We would like to highlight one case of cardiac perforation and taponade, one traqueal lesion and one case of external iliac vein injury. The injuries caused by glass (35.3%) and sharp arms (29,4%) were the most frequent mechanism. Simple suture and observation was treatment enough in 47.1%. Three patients required neural and vascular micro suture. One patient followed a thoracotomy procedure and other one, a sternotomy. It wasn't necessary any laparotomy. No patient died and 88% of the patients have no sequelae. CONCLUSIONS Most of the penetrating child traumas have good prognosis and are associated with few sequelae. Low energy thoracic and abdominal penetrating traumas can be managed conservatively when the patient is hemodiynamically stable and CT scan shows no organ injury, avoiding unnecessary surgical examinations.

Abstract
In female pseudohermaphroditism due to congenital adrenal hyperplasia (CAH), some cases develope a very important masculinization degree with a high outlet of the vagina above the outern urethral sphincter. There are several surgical techniques to solve this problem. Our group uses Passerini's thecnique since 1990. 9 Girls with CAH with extreme masculitation (IV and V Prader degree) have been operated with this technique. The age at intervention varies between 9 months and 3 years, with a follow-up between 1 and 12 years. All these patients had hormonal studies, demostrating a deficiency of 21-hydroxilase in 8 cases and a deficiency of 11-B-hydroxilase in one case. To determine the vaginal outlet a genitography was performed in all cases, vaginoscopy in 7 cases and MNR in 2 cases. Passerini's technique consists of two phases: the first step has the objective of forming the distal 2/3 of the vagina using the skin and the urethral mucosa of the phallus. At the second time transtrigonal way is performed to access the vagina which is desinserted from its urethral outlet and anastomosed with the distal neovagina. There were no significative complications in immediate time. The esthetic result is acceptable in all cases, although one case had to be surgically repaired because of a prominent vulvar flap. We use vaginoscopy to prove vaginal permeability in all cases although one of them developed adherences around the anastomosis. This severe genital malformation, very uncommon, has a difficult surgical solution. Passerini's technique allows, with less complications, to create an acceptable outer genitals at early age and only in one surgical time.

Abstract
The aim of this paper is to study possible synergic effects between crystallization-inhibitor molecules of low molecular weight on the hydroxyapatite and brushite crystal nucleation. Kinetic-turbidimetric measurements were performed to follow the nucleation process in synthetic urine at 37 degrees C. Only pyrophosphate + phytate mixture manifested synergic effects on the brushite nucleation, whereas the mixture pyrophosphate + citrate exhibited synergic effects only on the hydroxyapatite nucleation. It seems clear that synergic effects between the crystallization inhibitory capacity of some substances in urine can take place and as a consequence, the high crystallization inhibitory capacity of healthy urine could be assigned not only to the individual inhibitory capacity of each product but also to the synergic effects between different products.

Abstract
The aim of this study was to assess the effectiveness of endorectal MR imaging in predicting the positive biopsy results in patients with clinically intermediate risk for prostate cancer. We performed a prospective endorectal MR imaging study with 81 patients at intermediate risk to detect prostate cancer between January 1997 and December 1998. Intermediate risk was defined as: prostatic specific antigen (PSA) levels between 4 and 10 ng/ml or PSA levels in the range of 10-20 ng/ml but negative digital rectal examination (DRE) or PSA levels progressively higher (0.75 ng/ml year(-1)). A transrectal sextant biopsy was performed after the endorectal MR exam, and also of the area of suspicion detected by MR imaging. The accuracies were measured, both singly for MR imaging and combined for PSA level and DRE, by calculating the area index of the receiver operating characteristics (ROC) curve. Cancer was detected in 23 patients (28%). Overall sensitivity and specificity of endorectal MRI was 70 and 76%, respectively. Accuracy was 71% estimated from the area under the ROC curve for the total patient group and 84% for the group of patients with PSA level between 10-20 ng/ml. Positive biopsy rate (PBR) was 63% for the group with PSA 10-20 ng/ml and a positive MR imaging, and 15% with a negative MR exam. The PBR was 43% for the group with PSA 4-10 ng/ml and a positive MR study, and 13% with a negative MR imaging examination. We would have avoided 63% of negative biopsies, while missing 30% of cancers for the total group of patients. Endorectal MR imaging was not a sufficient predictor of positive biopsies for patients clinically at intermediate risk for prostate cancer. Although we should not avoid performing systematic biopsies in patients with endorectal MR imaging negative results, as it will miss a significant number of cancers, selected patients with a PSA levels between 10-20 ng/ml or clinical-biopsy disagreement might benefit from endorectal MR imaging.

Abstract
The columnar-cell variant of papillary carcinoma is a rare tumor of the thyroid, associated with aggressive behavior, early visceral metastasis, and a rapidly fatal course. In this report we present the fine-needle aspiration cytologic findings of two examples of this variant of papillary carcinoma with cytohistologic correlation. In the smears, clusters, monolayered sheets, and scattered papillary fronds of tumor cells were present. The tumor cells were columnar and exhibited overlapping and stratification of the nuclei. In the first case the tumoral cells showed round nuclei with finely granular chromatin pattern, small nucleoli and vacuolated-appearing cytoplasm. The malignant cells in the second case presented oval to elongated nuclei with stippled chromatin, inconspicuous nucleoli and indistinct cytoplasmic borders. It is important to distinguish this tumor from the common thyroid papillary carcinoma because of its much more aggressive behavior.

Abstract
Massive crystal deposition is unusual in lymphoproliferative disorders. In this report, a mucosa-associated lymphoid tissue (MALT) low-grade B-cell lymphoma of the parotid gland containing large numbers of crystal-storing histiocytes is described. The patient, an 81-yr-old female, presented with a history of long-standing left parotid gland enlargement. FNA cytology of the tumor showed a lymphoplasmacytic infiltrate and sheets of large benign histiocytes with abundant eosinophilic intracytoplasmic inclusions. Paraffinsection immunohistochemistry performed on the cell block demonstrated that the histiocytic cells were immunoreactive for the KP-1 (CD-68) antibody and monotypic for cytoplasmic IGM and L-light chain. The cytological diagnosis was consistent with a low-grade B-cell lymphoma with plasmacytic differentiation associated with crystal-storing histiosis. A periparotid lymph node was biopsied and showed involvement by a monocytoid B-cell lymphoma with plasmacytic differentiation and crystal-storing histiocytosis in the pericapsular region.
