    Objective: To understand how small producers perceive their agroforestry production unit (UPAF) from a social, economic, environmental, and technical context. Design/methodology/approach: A non-experimental qualitative analysis of the UPAF was performed. The information was collected through semi-structured interviews, participatory direct observation, and a field diary. The information was analyzed through codification, categorization, and the development of comparative and descriptive tables between the two municipalities and among the peasant families. Results: The UPAF provide socioeconomic, environmental, and technical-productive benefits to the producers who adopted and adapted the agroforestry system. Two factors influenced the adoption of the technology: age and technical monitoring. Limitations on study/implications: The main limitation of the present study was the small number of agroforestry production units and the specificity of the project, which restricts the generalization of results. Findings/conclusions: Agroforestry production units are consistent with the peasant economy, because they meet several of its characteristics: family productive unit, partial mercantile nature, undivided family work, way of playing with risk and belonging to a group. Therefore, these types of agroecological alternatives are viable for farmers.Objective: To understand how small producers perceive their family agroforestry production unit (UPAF) from a social, economic, environmental, and technical standpoint. Design/methodology/approach: A non-experimental qualitative analysis of several UPAFs was conducted. The information was gathered through semi-structured interviews, direct participatory observation, and a field diary. The said information was subsequently analyzed through codification, categorization, and the development of comparative and descriptive tables for the two municipalities and the farmer families in each one of them. Results: The UPAFs provide socioeconomic, environmental, and technical-productive benefits to the producers who have adopted and adapted this agroforestry system. Two factors have influenced the adoption of this technology: age and technical monitoring. Study limitations /implications: The main limitation of our study was the small number of agroforestry production units analyzed, as well as the specificity of the project, which restricts the generalization of results. Findings/conclusions: Agroforestry production units are consistent with a farmer economy because they match several of its characteristics: they are family production units with a partially mercantile nature, which require undivided family work, foster group belonging, and allow risk-taking. Therefore, these types of agroecological alternatives are viable for farmers

    Neoadjuvant intralesional methotrexate for juvenile xanthogranuloma in an adult

    Get PDF
    Juvenile xanthogranuloma (JXG) is a non-Langerhans cell histiocytosis usually occurring in infants and typically located in the head or neck.1 Clinically, solitary skin lesions are found in 60%–82% of patients and the most common variant is characterized by one yellowish nodule. Adult onset is rare, and although JXG is usually self-limiting in children, spontaneous resolution is uncommon at older ages. In addition, up to 50% of patients with spontaneous regression develop an atrophy or anetodermal area.2 Thus, complete excision is frequently performed in this population subgroup to achieve better cosmetic results. In disseminated forms, different chemotherapy regimens, corticosteroids and other systemic therapies are used. Herein, we report a case of adult JXG treated with intralesional methotrexate (MTX) resulting in a rapid reduction in size

    To the Editor: Some patients with congenital melanocytic nevi (CMN) present progressive growth and thickening, extracutaneous involvement (neurocutaneous melanocytosis, NCM) or neoplastic transformation (melanoma); and others remain stable or even regress. There are no markers to assess progression or follow-up. Recently, we found S-100, a protein which acts on cell differentiation and proliferation, elevated in CMN.1 S-100 is a ligand of the RAGE pathway (related to the MAPK-pathway), and low serum levels of soluble-RAGE were related to poor survival in melanoma.2 Also SOX10, expressed in melanocytes with high specificity, is useful in detection, prognosis and treatment assessment of melanoma.3 We explored if S-100, RAGE and SOX10 serum levels vary in children’s CMN and assessed clinical or pathological correlations

    Volteando la tortilla. Género y maíz en la alimentación actual de México.

    Get PDF
    Ante escenarios complejos, patriarcales y desoladores que dejan ver el neoliberalismo, la globalización agroalimentaria, el calentamiento global y las contaminaciones de granos nativos por la imposición de transgénicos, nos cuestionamos si existen algunas alternativas para preservar el maíz nativo como un recurso multiestratégico (alimentario, económico, cultural, ecológico y tecnológico) tomando en cuenta las condiciones actuales de desigualdades sociales de género, etnia, clases y edad que predominan en el campo mexicano. Para responder a algunos cuestionamientos, este libro presenta algunas alternativas a través de diversas experiencias femeninas y de relaciones de género en torno al maíz y la alimentación. Todas ellas muestran que es posible construir una masa crítica para salvaguardar el maíz nativo bajo esas condiciones desoladoras, pero siempre y cuando se “voltee la tortilla”, metáfora que da pie al inicio de otra realidad humanizada y en sincronía con la naturaleza.Proyecto realizado con financiamiento Conacy

    A facility and community-based assessment of scabies in rural Malawi.

    Background Scabies is a neglected tropical disease of the skin, causing severe itching, stigmatizing skin lesions and systemic complications. Since 2015, the DerMalawi project provide an integrated skin diseases clinics and Tele-dermatology care in Malawi. Clinic based data suggested a progressive increase in scabies cases observed. To better identify and treat individuals with scabies in the region, we shifted from a clinic-based model to a community based outreach programme. Methodology/principal findings From May 2015, DerMalawi project provide integrated skin diseases and Tele-dermatological care in the Nkhotakota and Salima health districts in Malawi. Demographic and clinical data of all patients personally attended are recorded. Due to a progressive increase in the number of cases of scabies the project shifted to a community-based outreach programme. For the community outreach activities, we conducted three visits between 2018 to 2019 and undertook screening in schools and villages of Alinafe Hospital catchment area. Treatment was offered for all the cases and school or household contacts. Scabies increased from 2.9% to 39.2% of all cases seen by the DerMalawi project at clinics between 2015 to 2018. During the community-based activities approximately 50% of the population was assessed in each of three visits. The prevalence of scabies was similar in the first two rounds, 15.4% (2392) at the first visit and 17.2% at the second visit. The prevalence of scabies appeared to be lower (2.4%) at the third visit. The prevalence of impetigo appeared unchanged and was 6.7% at the first visit and 5.2% at the final visit. Conclusions/significance Prevalence of scabies in our setting was very high suggesting that scabies is a major public health problem in parts of Malawi. Further work is required to more accurately assess the burden of disease and develop appropriate public health strategies for its control

    Nasal Dorsum Rotation–Transposition Flap Associated with Guitar-String Sutures: One-Stage Reconstruction of Large Defects on the Nose

    No full text
    (1) Background: The preferred reconstructive option for closing small- or medium-sized defects of the distal half of the nose is the use of local flaps. The dorsal nasal (Rieger) flap is suitable for closing medium-sized defects at this location, especially when they are medially located, and are wider rather than tall. We describe a rotation–transposition dorsal nasal flap reconstruction for large nasal defects. The novelty of this design includes the addition of a small transposition lobe to the rotation flap, enabling the acquisition of tissue from either the lateral sidewall or the nasolabial sulcus, facilitating closure with guitar-string sutures. (2) Methods: We conducted a retrospective chart review of all the patients with large defects (>20 mm) of the nose who underwent nasal dorsum rotation–transposition flap repair between January 2019 and November 2022 at a single academic center. (3) Results: Fourteen patients (eight males, six females; ages 47–83, mean age 60 years) with defects (range: 20.00–35.00 mm) on the dorsum and nasal tip were recruited. Follow-up duration ranged from 12 months to 3 years, with all cases showing good or excellent oncologic and cosmetic results. (4) Conclusions: The rotation–transposition dorsal nasal flap was demonstrated to be a reproducible one-stage technique for large defects of the dorsum and nasal tip, with minimal risk of aesthetic or functional complications. Guitar-string sutures allowed the reduction of the defect size, facilitating a smaller flap design

    Simplified lower eyelid reconstruction algorithm after basal cell carcinoma surgery: A retrospective series of patients

    No full text
    The lower eyelid is a frequent location for basal cell carcinoma (BCC), and oncoplastic reconstruction usually represents a challenge for the dermatologic surgeon. To create a useful and practical algorithm for lower eyelid reconstruction, a retrospective chart review of patients with lower eyelid BCC treated with surgery between 2015 and 2020 at the dermatology department of University Clinic of Navarra in Spain was performed. Defects were classified into three categories based on the vertical component: pretarsal, preseptal and complex (pretarsal + preseptal)1 (Table 1). Patients with BCC on the eyelid-cheek junction (n = 4), patients with BCC extended to both eyelids (n = 3) and patients with extensive posterior lamella defects that required a particular reconstruction of the lamella (n = 5) were excluded

    Apremilast in combination with botulinum toxin-A injection for recalcitrant Hailey-Hailey disease

    No full text
    Hailey–Hailey disease (HHD) is a rare genodermatosis caused by a mutation in the ATP2C1 gene, which codes for a calcium channel. This ionic alteration leads to a defective keratinocyte adhesion. Hailey–Hailey disease is characterized by recurrent flare-ups of vesicles and flaccid blisters in folds that have an impact on patients’ quality of life. The recurrent and refractory nature of this condition makes its treatment a challenge. Isolated cases have been reported describing controversial results after treatment with apremilast. Here we present a case of refractory HHD who experienced an excellent response after treatment with apremilast and botulinum toxin-A (BoNT) infiltrations
