Recopilación de insecticidas, acaricidas y fungicidas registrados para el cultivo de cucurbitáceas en Argentina

The large and diverse horticultural production in Argentina is carried out intensively and extensively in all the territory, even as subsistence farming carried out by families. Horticultural crop products are mainly sold fresh which is the reason why they must fulfill innocuousness requirements for family consumption. According to this, the chemical control over the variety of pests that harm this production must rely on duly registered phytosanitary products with low impact on the environment. Phytosanitaires must be responsibly well-managed, considering waiting period and correct dosage in each case. As a result, bibliographic compilation of registered phytosanitary products for the Cucurbitaceae family was carried out. That would help technicians make decisions on the various situations that arise in the field when opting for chemical control. This work includes charts for each species traditionally produced in NEA, elaborated with the active ingredients registered for: pumpkin, melon, cucumber, watermelon, squash and zucchini. Moreover, this work provides the Environmental Impact Quotient (EIQ) values that correspond to each use recommendation made in order to offer other criteria for the selection of the active ingredient to be used.La extensa y variada producción hortícola en la República Argentina se lleva a cabo de manera intensiva, extensiva e incluso como cultivo de subsistencia en huertas familiares. Sus productos se comercializan principalmente en fresco, razón por la cual deben cumplir con la tan necesaria condición de inocuidad para las familias que los consumen. De acuerdo con esto, el control químico de las distintas plagas que perjudican a esta producción debe basarse en la utilización de productos fitosanitarios debidamente registrados, con bajo impacto en el medio, con un uso responsable, manejo adecuado y considerando el tiempo de carencia y dosis para cada caso. A raíz de todo esto, se elaboró una recopilación bibliográfica de los fitosanitarios registrados para la familia de las Cucurbitáceas con el fin de facilitar a los técnicos la toma de decisiones frente a las diversas situaciones que se presentan a campo a la hora de optar por el control químico. El siguiente trabajo cuenta con tablas por cultivo, elaboradas con los principios activos registrados para cada una de las especies tradicionalmente producidas en el NEA, las cuales son calabaza, melón, pepino, sandía, zapallo y zapallito de tronco o redondo. Además, en el presente trabajo, se brinda los valores del Coeficiente de Impacto Ambiental (EIQ) para cada recomendación de uso lo cual es un criterio más para la selección del principio activo a utilizar

A review of the literature of surgical and nonsurgical treatments of invasive squamous cells carcinoma

Cutaneous squamous cell carcinoma (cSCC) is an increasing public health problem. It is a primary malignant skin tumor with Malpighian differentiation and together with basal cell carcinoma is classified among nonmelanoma skin cancers (NMSCs). cSCC usually occurs on photoexposed areas, such as the head, the neck, and the extremities, and its incidence increases with age. Invasive forms of this skin tumor tend to be more aggressive showing a higher metastatic potential, usually regarding regional lymph nodes. Treatment options for invasive cSCCs include both surgical and nonsurgical options. The therapeutic choice depends on several factors, such as anatomic location, risk factors for tumor recurrence, age, and health status of the patient. This review aims to provide an overview of the current evidence on therapeutic surgical and nonsurgical management of invasive cSCC

IL-17 and its role in inflammatory, autoimmune, and oncological skin diseases. State of art

Recent data support the theory of the involvement of IL-17 in the pathogenesis of several chronic inflammatory skin diseases (psoriasis, atopic dermatitis, acne, hidradenitis suppurativa) and autoimmune skin diseases (alopecia areata, vitiligo, bullous diseases). Even if the role of IL-17 in inflammatory and autoimmune diseases has been reported extensively, its role in tumor is still controversial. Some reports show that Th17 cells eradicate tumors, while others reveal that they promote the initiation and early growth of tumors. Herein, we review the role of IL-17 in the involvement of some common dermatologic diseases: psoriasis, atopic dermatitis, hidradenitis suppurativa, acne, vitiligo, melanoma, and nonmelanoma skin cancers

Therapeutic options for the treatment of actinic keratosis with scalp and face localization

Actinic keratosis (AK) is a common skin disease related to ultraviolet chronic exposure, that is now considered a squamous cell carcinoma in situ. Primary skin cancer prevention strategies should be recommended for high risk patients. There is a wide spectrum of treatment options available for AKs, and several variables should be taken into account regarding the best therapeutic choice for each patient. The purpose of this article is to review the current treatment strategies for AKs localized on the face and scalp, with a focus on the practical point of view that could be useful for choosing the best therapeutic option. The two main therapeutic approaches will be distinguished first: lesion-directed and field-directed. Afterwards, the treatment based on clinical type and patient comorbidity will be discusse

Urticaria in an infant with SARS-CoV-2 positivity

Last months have been marked by the global spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for the coronavirus disease 19 (COVID-19) pandemic

A late onset widespread skin rash in a previous Covid-19 infected patient. Viral or multidrug effect?

In the end of 2019, a series of pneumonia cases emerged in China, with clinical presentations greatly resembling viral pneumonia, caused by Covid-19 o SARS-CoV-2. Currently, several clinicians described an increasingly cases of coronavirus-positive patients reporting skin problems, either in early stage of infection or as late onset manifestation. Recently, Dr. Sebastiano Recalcati analyzed the cutaneous involvement in 148 COVID-19 patients hospitalized in the Lecco Hospital, Lombardy, Italy

Batata con sanidad controlada. Modelo productivo para la provincia de Corrientes

Las regiones productoras de batata del país han sufrido disminución de la superficie plantada, con mermas de rendimientos de las principales variedades comerciales. Esto se atribuye a enfermedades causadas por la sinergia de al menos cinco virus de difícil detección, incluso a través de métodos serológicos/moleculares. La infección durante el ciclo de cultivo se produce a través de insectos vectores: pulgones y moscas blancas. Los efectos de estas enfermedades pueden mitigarse con el uso de material de propagación agámica de sanidad controlada, multiplicado a partir de semilla básica o fundación provista por el Instituto de Patología Vegetal (IPAVE), Córdoba, que se obtiene a su vez, mediante micropropagación in vitro de meristemas y termoterapia. La multiplicación masiva se realiza a través de viveros en las diferentes zonas productoras del país. En 2017 el Ministerio de Producción de Corrientes creó el programa Multiplicación de Batata con Sanidad Controlada, mediante el cual puso en funcionamiento el Vivero Hortícola del Centro Tecnológico de Producción, con diferentes cultivares (cvs). La macropropagación se realiza en invernadero cumpliendo con el protocolo sanitario establecido. La producción obtenida se destina principalmente a productores comerciales beneficiarios del Proyecto, que llevan adelante sus propios “núcleos semilleros”, donde se plantan los esquejes saneados y a partir de los cuales se obtiene material de propagación para lotes comerciales. Estos núcleos se encuentran protegidos con malla anti-insecto. Con lo que se pretende bajar la presión de inóculo, recuperar superficie y calidad de producción

Seleção de linhagens de feijão com base no padrão e na qualidade de sementes.

RESUMO - A seleção de linhagens de feijão pelo padrão de tegumento, qualidade sanitária e fisiológica de sementes é recente nos programas de melhoramento. Por isso, foram objetivos deste trabalho avaliar se as linhagens de feijão diferem quanto ao padrão de tegumento, a qualidade sanitária e fisiológica de sementes, investigar a associação entre esses caracteres e selecionar linhagens de feijão superiores para a qualidade de sementes. Para tanto, foram avaliadas 16 linhagens de feijão de diferentes obtentores em cultivo de safra agrícola. As linhagens de feijão apresentaram diferença significativa em relação ao peso de mil sementes, coloração do tegumento, conteúdo de lignina, comprimento, largura e espessura das sementes, incidência de Fusarium sp., germinação, primeira contagem de germinação, envelhecimento acelerado, comprimento da parte aérea, da raiz e total das plântulas, massa seca da parte aérea e total das plântulas e emergência de plântulas a campo. A estimativa de correlação positiva foi observada entre a emergência de plântulas a campo e a germinação (r = 0,650), a primeira contagem de germinação (r = 0,600), o envelhecimento acelerado (r = 0,793) e a condutividade elétrica (r = 0,635). A seleção indireta pela germinação, primeira contagem de germinação e envelhecimento acelerado foi eficiente para a identificação de linhagens de feijão com maior emergência de plântulas a campo. A seleção das linhagens TB 02-07, SM 1810, Carioca, LP 08-90, SM 1107, LP 07-80, Pérola, CNFP 10104 e TB 02-24 é recomendada para uso em programas de hibridação controlada para o desenvolvimento de novas cultivares de feijão de alta qualidade de sementes. ABSTRACT - The selection of common bean lines for seed coat standard, sanitary and physiological quality seed is recent in breeding programs. The objectives of this research were to evaluate if common bean lines differ for seed coat standard, sanitary and physiological quality seed, to investigate the correlation between these characters and to select common bean lines with high seed quality. For this, 16 inbred common bean lines were evaluated in normal rainy growing season. The common bean lines showed significant difference for the weight of thousand seeds, seed coat color, lignin content, length, width and thickness seeds, Fusarium sp. incidence, germination, first germination count, accelerated ageing, length of shoot, root and total of seedling, dry matter of shoot and total of seedling and emergency of seedling in field. A positive correlation coefficient was found between emergency of seedling in field and germination (r = 0.650), first germination count (r = 0.600), accelerated ageing (r = 0.793) and electric conductivity (r = 0.635). The indirect selection by germination, first germination count and accelerated ageing is effective to identify common bean lines with the highest emergency of seedling in field and germination. The selection of TB 02-07, SM 1810, Carioca, LP 08-90, SM 1107, LP 07 -80, Pérola, CNFP 10104 and TB 02-24 lines is recommended for use in controlled hybridization programs for improvement of news common bean cultivars of high seeds quality.Título em inglês: Selection of common bean lines for standard and quality seeds

Similar levels of efficacy of two different maintenance doses of adalimumab on clinical severity and quality of life of patients with hidradenitis suppurativa

Adalimumab is the only biologic agent approved for the treatment of moderate-to-severe hidradenitis suppurativa (HS) patients (i.e., with Hurley II or III), which is recommended in two different maintenance doses (i.e., 40 mg weekly or 80 mg every two weeks). We conducted a prospective multicentric study to measure outcomes related to the severity of disease and quality of life (QoL) of patients affected by moderate-to-severe HS, treated with adalimumab at a maintenance dosing of 40 mg or 80 mg. Assessments were performed at baseline (T0) and after 32 weeks of treatment (T32). We enrolled 85 moderate-to-severe HS Italian patients, 43 men (50.6%) and 42 women, aged between 16 and 62 years (median 31 years, interquartile range 24.4-43.8). Statistically significant improvements were observed for clinical status (with a mean reduction of 7.1 points for the International Hidradenitis Suppurativa Severity Score System (IHS4)), pain levels (3.1 mean decrease in VAS), and QoL (3.4 mean improvement in DLQI score). Patients with no comorbidities, and those with higher levels of perceived pain showed significantly greater improvement in QoL than their counterpart from T0 to T32. As for the proportion of patients who at follow-up reached the minimal clinical important difference (MCID) in QoL, significantly higher proportions of success were observed for age (patients in the 29-39 category), pain (patients with higher reported pain), and Hurley stage III. While both treatment regimen groups (i.e., 40 vs. 80 mg) improved significantly, no statistical differences were observed when comparing the two treatment dosages
