Efficacy and safety profile of vismodegib in a real-world setting cohort of patients with advanced basal cell carcinoma in Argentina.

Introduction And Objectives: Vismodegib (Erivedge ), a hedgehog pathway inhibitor, is approved to treat metastatic or locally advanced basal cell carcinoma (BCC) not suitable for surgery or radiotherapy. Our main objectives were to study the objective response rate (ORR) assessed by treating physicians and safety of vismodegib in a real-world practice setting in Argentina.

Material And Methods: This is a prospective cohort study in real-world practice.

Validation and comparison of analytical methods for the determination of histamine in tuna fish samples.

Histamine is a degradation product of the bacterial decarboxylation of the amino acid histidine, which is present in large amounts in fish tissues of the Clupeidae and Scombridae families and its presence is an indicator of good manufacturing practices and of the state of preservation of some food. A capillary electrophoresis and high-performance liquid chromatography method with diode arrays detection (HPLC-DAD) were compared and validated: no laborious pre-treatment, no clean up and no derivatization was necessary. In both techniques the correlation coefficient exceeded 0.

Validation of a high-performance liquid chromatography method for the determination of oxytetracycline, tetracycline, chlortetracycline and doxycycline in bovine milk and muscle.

High-performance liquid chromatography with diode-array detection (HPLC-DAD) was optimised and validated for the determination of tetracyclines in bovine milk and tissues. Milk and tissue samples were extracted and purified using a solid-phase extraction HLB Oasis cartridge and analysed using HPLC-DAD set at 365 nm. The analyses were carried out using the mobile phase of 0.

Determination of benzimidazole anthelmintics in animal-derived biological matrices.

This paper describes an easy multiresidue procedure for the determination of 8 benzimidazole anthelmintics (Albendazole, Albendazole sulphone, Albendazole sulphoxide, Ox-bendazole, Ossibendazole, p-OH-Fenbendazole, Fenbendazole, Flubendazole) in foodstuffs of animal origin for human consumption. According to the proposed procedure, 10 g of homogenised sample were extracted with acetonitrile in ultrasonic bath, the organic layer was evaporated to dryness and the residue dissolved in HCl 0.005 M.

[Calcification of the tunica vaginalis testis].

Objective: To describe a case of calcification of the tunica vaginalis testis.

Methods: A 66-year-old patient with right hydrocele and superficial carcinoma of the bladder who underwent TUR and was treated with mitomycin prophylactic instillations, is described. The patient presented a bulbar urethral stricture.
