ABSTRACT

A 75-year-old man with human immunodeficiency virus infection and numerous biopsy-proven warts for 10 years, refractory to cryosurgery, cimetidine, and topical imiquimod, presented with numerous pink to hypopigmented verrucous papules and plaques involving the face, trunk, buttocks, and groin. Laboratory evaluation revealed a CD4 T-cell count of 62 cells per microliter and human immunodeficiency virus viral load of <117 copies per milliliter. Biopsy of a plaque groin lesion was performed. Histopathology revealed vertically oriented anastomosing strands of basaloid epithelium arising from multiple points along the epidermis in a background fibrovascular stroma. Ductal differentiation was identified. Areas of epidermis showed compact orthokeratosis, coarse hypergranulosis, and keratinocytes with abundant steel-blue-gray cytoplasm, indicative of viral cytopathic changes. Cytologic atypia was not identified. Human papillomavirus (HPV) genotyping of this lesion was positive for types 5 and 14. Overall, the findings were consistent with epidermodysplasia verruciformis in association with eccrine syringofibroadenoma (ESFA). The patient was subsequently treated with acitretin and showed clinical improvement. ESFA is an uncommon benign adnexal tumor with unknown pathogenesis. Although its association with HPV has rarely been reported, ESFA in the setting of acquired epidermodysplasia verruciformis has not been described. The development of ESFA in this case may be the result of HPV-induced cellular transformation.

ABSTRACT

The monitoring of Aedes urban species is usually conducted by ovitraps, which can provide a good estimate of population density at low cost and relatively easy management. When the monitoring network is managed by many operators, as in the case of the Emilia-Romagna regional plan, it becomes necessary to develop a quality control methodology capable of highlighting the possible data incoherency and ensuring that the monitoring system provides reliable data.This paper presents the procedure applied in the egg counting phase as developed in Emilia-Romagna in order to check the data quality and validate the data before being included in the database.Several steps have been identified and protocols developed to serve quality control such as training of technicians and intralaboratory quality check, daily random double counting of Masonite paddles and interlaboratory periodic comparison.The qualitative test showed that all operators were able to distinguish Aedes albopictus eggs from other mosquito species eggs. The quantitative test showed significant differences between the 11 operators, with a relative error resulting in the range of 0.1-25.8%.The daily internal double counting of randomly extracted Masonite slides was performed by the coordinator showing a relative error in the range 2.47-2.63% without statistical differences, confirming a good alignment of the operators with the coordinator throughout the monitoring period.The interlaboratory comparison trial produced an average relative error of 7.20% showing a sufficient alignment between the three laboratories.Moreover a new time-saving methods in egg counting was developed and tested in real condition.

ABSTRACT

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare, severe mucocutaneous reaction with few large cohorts reported. This multicenter retrospective study included patients with SJS/TEN seen by inpatient consultative dermatologists at 18 academic medical centers in the United States. A total of 377 adult patients with SJS/TEN between January 1, 2000 and June 1, 2015 were entered, including 260 of 377 (69%) from 2010 onward. The most frequent cause of SJS/TEN was medication reaction in 338 of 377 (89.7%), most often to trimethoprim/sulfamethoxazole (89/338; 26.3%). Most patients were managed in an intensive care (100/368; 27.2%) or burn unit (151/368; 41.0%). Most received pharmacologic therapy (266/376; 70.7%) versus supportive care alone (110/376; 29.3%)-typically corticosteroids (113/266; 42.5%), intravenous immunoglobulin (94/266; 35.3%), or both therapies (54/266; 20.3%). Based on day 1 SCORTEN predicted mortality, approximately 78 in-hospital deaths were expected (77.7/368; 21%), but the observed mortality of 54 patients (54/368; 14.7%) was significantly lower (standardized mortality ratio = 0.70; 95% confidence interval = 0.58-0.79). Stratified by therapy received, the standardized mortality ratio was lowest among those receiving both steroids and intravenous immunoglobulin (standardized mortality ratio = 0.52; 95% confidence interval 0.21-0.79). This large cohort provides contemporary information regarding US patients with SJS/TEN. Mortality, although substantial, was significantly lower than predicted. Although the precise role of pharmacotherapy remains unclear, co-administration of corticosteroids and intravenous immunoglobulin, among other therapies, may warrant further study.

ABSTRACT

BACKGROUND: Neglected tropical diseases (NTDs) impact disadvantaged populations in resource-scarce settings. Availability of synthesized evidence is paramount to end this disparity. The aim of the study was to determine whether NTD systematic reviews or protocols in the Cochrane Database of Systematic Reviews (CDSR) reflect disease burden. METHODS: Two authors independently searched the CDSR for reviews/protocols regarding the NTDs diseases. Each review or protocol was classified to a single NTD category. Any discrepancy was solved by consensus with third author. NTD systematic review or protocol from CDSR were matched with disability-adjusted life year (DALY) metrics from the Global Burden of Disease 2010 Study. Spearman's rank correlation coefficient and associated P values were used to assess for correlation between the number of systematic reviews and protocols and the %2010 DALY associated with each NTD. RESULTS: Overall, there was poor correlation between CDSR representation and DALYs. Yellow fever, echinococcus, onchocerciasis, and schistosomiasis representation was well-aligned with DALY. Leprosy, trachoma, dengue, leishmaniasis, and Chagas disease representation was greater, while cysticercosis, human African trypanosomiasis, ascariasis, lymphatic filariasis, and hookworm representation was lower than DALY. Three of the 18 NTDs had reviews/protocols of diagnostic test accuracy. CONCLUSIONS: Our results indicate the need for increased prioritization of systematic reviews on NTDs, particularly diagnostic test accuracy reviews.

ABSTRACT

The main objective of this paper is to present a technique for computing the membership functions of the intuitionistic fuzzy set (IFS) by utilizing imprecise, uncertain and vague data. In literature so far, membership functions of IFS are computed via using fuzzy arithmetic operations within collected data and hence contain a wide range of uncertainties. Thus it is necessary for optimizing these spread by formulating a nonlinear optimization problem through ordinary arithmetic operations instead of fuzzy operations. Particle swarm optimization (PSO) has been used for constructing their membership functions. Sensitivity as well as performance analysis has also been conducted for finding the critical component of the system. Finally the computed results are compared with existing results. The suggested framework has been illustrated with the help of a case.

ABSTRACT

A series of novel 3,4-disubstituted pyrazoles were synthesized. The cytotoxicity against U87MG glioma cell line have been investigated in vitro and three of these compounds showed promising inhibitory activity on cell growth with an IC50 lower than 90 microM. AutoDock molecular docking into type I TGF-beta receptor (TGF-beta-RI; PDB: 1py5) has been done for lead optimization of the mentioned compounds as potential TGF-beta-RI1 inhibitors. In particular, 3-aryl-4-amido pyrazole containing long omega-amino-aliphatic chain emerged as a good candidate for further optimization. Entrapment into targetable PEG-based micelles improved growth inhibition IC50 values up to 100 nM and this could lead to a novel drug delivery strategy for treating glioblastoma.
