Abstract Introduction: A correlation is made regarding osteoarthrosis and working conditions and lifestyles of informal workers in Medellin downtown. Objective: To identify the prevalence of chronic and degenerative diseases, and the relationship of osteoarthritis with sociodemographic and work conditions, habits and lifestyles, in a group of informal workers from Medellín, Colombia. Materials and methods: Cross-sectional study, with a primary source of information, with 686 workers. An assisted survey was applied, after obtaining consent. 289 workers with a diagnosis of chronic or degenerative disease, ≥18 years old, with ≥5 years in their profession were included. Exploratory and association analysis with Chi2 test, and calculation of PR with 95% CI. Results: 79.9% of them suffered from a chronic disease. 3.46% had a diagnosis of osteoarthrosis, being significantly higher (p <0.05) in those who had spent between 21 and 30 years performing their profession (PR=5,62.CI:1,20;26,34). The prevalence of osteoarthrosis was also higher in; >45 years (PR=2.26), women (PR=4,44), sedentary workers (PR=1,71), obese (PR=3,40), as well as those who had been brick-layers (PR=1,30), in those who had semi-stationary sales positions (PR=2,21), they sold harvest and perishable products (PR=1,78), in those who worked> 8 hours a day (PR:2,77), ≤ 5 days a week (PR=3,10), they did not have enough space to move (PR = 2.08), and in those who had forced postures or movements (PR=2,72). Conclusion: sociodemographic and work factors, habits and modifiable lifestyles are related to a higher prevalence of osteoarthrosis in this working population.

Urinary bladder lipoma: an illustrative case.

Urinary bladder lipomas are rare neoplasms. Therefore, very few of them have been reported in the literature. We present a case that illustrates the typical features that allow radiologists to diagnose this entity: a solid lesion that arises from the urinary bladder wall, showing an endophytic growth and homogeneous hypoattenuation. After its surgical resection, the diagnosis was confirmed by anatomo-pathological analysis. In the discussion we describe other neoplasms that should also be considered when a submucosal bladder neoplasm is detected on computed tomography or other imaging techniques.

Inonotosis in Patient with Hematologic Malignancy.

We report a lung-invasive fungal disease with possible cutaneous needle tract seeding in a patient with a febrile neutropenia caused by the Basidiomycetes mold Inonotus spp. Although rare, Inonotus spp. should be added to the list of microorganisms causing invasive fungal disease in neutropenic patients with hematologic malignancies.

Exclusion criteria vs reality: dual BRAF/MEK inhibition and radiotherapy in a patient with melanoma metastatic to the brain and ECOG 3.

BACKGROUND: Prognosis of metastatic melanoma is changing due to advances in immunotherapy and targeted therapy. However, management of patients with brain metastases in day-to-day practice continues to be a challenge. CASE REPORT: We describe a 40-year-old woman diagnosed with symptomatic brain metastases from cutaneous melanoma and Eastern Cooperative Oncology Group 3. She was treated, off label, with BRAF inhibitor (dabrafenib) + MEK inhibitor (trametinib) and radiotherapy. There was significant, long-lasting, response (17 months), no clinically relevant toxicity, and clear improvement in quality of life. CONCLUSIONS: This case is an example of real-life application of advances in targeted therapy.

Análisis mediante radiografía convencional de los tejidos dentales y periodontales de cerdo (Sus domesticus) sometidos a altas temperaturas / Conventional X-ray analysis of porcine (Sus domesticus) periodontal and dental tissue subjected to high temperature

Introducción: La implementación de modelos animales para el estudio de los tejidos dentales y periodontales de dientes articulados en sus alvéolos sometidos a altas temperaturas permite el establecimiento de parámetros repetitivos que contribuyen con los procesos de identificación. Objetivo: Describir los cambios radiográficos de los tejidos dentales y periodontales de cerdo (Sus domesticus) sometidos a altas temperaturas. Material y métodos: Se realizó un estudio observacional descriptivo de naturaleza pseudo-experimental in vitro para observar los cambios radiográficos de los tejidos dentales y periodontales en 60 dientes de cerdo doméstico sometidos a altas temperaturas (200, 400, 600, 800 y 1,000 ºC). Resultados: Los tejidos dentales y periodontales estudiados presentan gran resistencia a las altas temperaturas sin variar considerablemente su microestructura, de tal manera que los cambios físicos (estabilidad dimensional, fisuras, grietas y fracturas) que ocurren en la medida que aumenta la temperatura pueden describirse a través de radiografía convencional. Conclusiones: El análisis radiográfico de los dientes articulados en sus respectivos alvéolos se constituye en un mecanismo para determinar la temperatura a la cual estuvo sometido un diente, lo que puede ser empleado durante el proceso de identificación odontológica y documentación de la necropsia médico-legal para el caso de cadáveres o restos humanos quemados, carbonizados e incinerados. El cerdo doméstico (Sus domesticus) se constituye en un modelo animal experimental adecuado para estudiar dichos cambios; sin embargo, se recomienda realizar un estudio en dientes humanos articulados en su respectiva unidad alveolar, para determinar si los hallazgos radiográficos descritos se repiten y son extrapolables.

Introduction: The implementation of animal models for the study of periodontal and dental tissues of teeth articulated into their sockets and subjected to high temperatures allows the establishment of repetitive parameters which might contribute to identification processes. Aim: To describe radiographic changes of pig's (Sus domesticus) periodontal and dental tissues subjected to high temperatures. Material and methods: An in vitro pseudo-experimental, descriptive and observational study was undertaken in order to assess radiological changes of periodontal and dental tissues of 60 domestic pig's teeth which had been subjected to high temperatures (200, 400, 600, 800 and 1,000 ºC). Results: The dental and periodontal tissues subject of this research article presented strong resistance to high temperatures without considerable variation of their micro-structure. Thus, physical changes (dimensional stability, fissures, cracks and fractures) which took place as temperature increased, could be described using a conventional X-ray. Conclusions: Radiographic examination of teeth articulated in their sockets can be established as a mechanism to determine the temperature at which the tooth was subjected. This could be used in processes of dental identification and medical-legal autopsy documentation in cases of burned, carbonized or incinerated human remains. Domestic pigs (Sus domesticus) can be regarded as a suitable experimental animal models to study the aforementioned changes. Nevertheless, a study involving human teeth articulated in their own socket is recommended in order to determine whether the radiographic findings herein described are replicated and can be extrapolated.

Metastatic melanoma with spontaneous regression, psoriasis and HLA-Cw6: case report and a hypothesis to explore.

Spontaneous regressions of metastatic melanoma are rare, but several cases have been described in the literature. Although the mechanism of the phenomenon is not well understood, it is postulated that an activation of the immune system is behind it. Here we report the case of a patient with metastatic melanoma that, without any treatment, regressed spontaneously. The patient presented psoriasis (a disease of the skin related with autoimmunity) linked with HLA-Cw6. We review the literature and hypothesize with the possible relationship between psoriasis, HLA-Cw6 and the spontaneous regression.

The prevalence of fatigue following deep brain stimulation surgery in Parkinson's disease and association with quality of life.

Fatigue is a common and disabling nonmotor symptom seen in Parkinson's disease (PD). While deep brain stimulation surgery (DBS) improves motor symptoms, it has also been associated with non-motor side effects. To date no study has utilized standardized instruments to evaluate fatigue following DBS surgery. Our objective was to determine the prevalence of fatigue following DBS surgery in PD its impact on quality of life and explore predictive factors. We recruited 44 PD subjects. At least one year following DBS placement, we administered the Fatigue Severity Scale (FSS), the Parkinson's Disease Questionnaire (PDQ-39), the Beck Depression Inventory, the Beck Anxiety Inventory, the UPDRS, and a neuropsychological battery. Fifty-eight percent of subjects had moderate to severe fatigue. Fatigue was significantly associated with quality of life, depression, and anxiety. Depression preoperatively was the only predictive factor of fatigue. Fatigue is common following DBS surgery and significantly impacts quality of life.

Nonmotor manifestations of dystonia: a systematic review.

Nonmotor symptoms are increasingly recognized as important determinants of quality of life and disability in a wide range of movement disorders. There is a limited body of research suggesting that many of these symptoms are also commonly associated with primary and other genetic forms of dystonia. However, the significance, etiology, pathophysiology, and treatment of these symptoms remain poorly described. The following is a review of the literature that focuses primarily on the association of these types of dystonia with psychiatric disorders, cognition, sleep, pain, and autonomic symptoms. We will also discuss potential mechanisms and approaches to treatment for nonmotor features of dystonia.

Cryoablation time-dependent dose-response effect at minimal temperatures (-80 degrees C): an experimental study.

AIMS: To establish a temporal safety window for cryoablation at minimal temperatures and to assess the electrophysiological and histological changes as a function of the application duration. METHODS AND RESULTS: Twenty mini-pigs underwent AV nodal cryoablation at -80 degrees C without prior cryomapping. The duration of the cryoapplication following atrioventricular block (AVB) was randomized to 0, 10, 20, 40, or 60 s. Atrioventricular block was obtained in all animals after a median of 3 (1-8 interquartile range) applications. One week later, AV nodal conduction fully recovered in animals with application duration <10 s, whereas persistent AVB incidence increased as a function of time in animals with longer applications duration. Cryoablation application duration following AVB was the only independent predictor of persistent AVB (OR, 1.116; 95% CI, 1.013-1.229; P = 0.026). There was no difference in lesion location or size between animals with vs. those without persistent AVB at 1 week. However, animals randomized to longer application duration demonstrated higher degree of cell destruction and fibrotic content. CONCLUSION: In this closed-chest pig model, there was a relation between cryoapplication duration following AVB at -80 degrees C and recovery of conduction. A safety window of at least 10 s was observed in all cases.

The dasyscyphins A-C and niveulone, new biologically active compounds from the ascomycete Dasyscyphus niveus.

In the course of a screening for cytotoxic compounds from fungi four new terpenoid metabolites, named dasyscyphins A, B, C, and niveulone were isolated from fermentations of Dasyscyphus niveus strain A0101. While dasyscyphin A (1) exhibited no significant biological activities in our test systems dasyscyphin B (2) and dasyscyphin C (3) showed cytotoxic activities against human (HepG2, Hela S3, U937, Colo-320, Jurkat) cell lines with IC50-values of 0.5-3 microg/ml while the activity of niveulone (4) was less pronounced. Only modest or weak antibiotic properties were observed for (2) and (3).

Niveulone, a heterocyclic spiro terpenoid from the ascomycete Dasyscyphus niveus.

The new heterocyclic spiro terpenoid niveulone (1) was isolated from the cultural fluid of the ascomycete Dasyscyphus niveus, and its chemical structure and relative configuration were determined by spectroscopic techniques.

Conocimiento de la ley y la violencia doméstica que maneja el médico familiar en la atención de violencia de pareja / Knowledge of the land and violence handle the family physicians in the attention of the spouse abuse

Se realizó un estudio exploratorio-descriptivo a 52 médicos familiares de los diferentes centros de salud del Distrito Federal, del Instituto Venezolano de los seguros Sociales y de los Centros Ambulatorios de Salud (SUSALUD) durante el período abril 1999-marzo 2000, con el propósito de: determinar el conocimiento de la Ley de la Violencia Doméstica que manejaba el Médico Familiar en la atención de Violencia de Pareja; si había recibido información y/o capacitación del tema, (información de la Ley sobre la Violencia contra la mujer y la familia); así como de las funciones de los médicos que se establece en la Ley sobre la Violencia contra la mujer. En términos generales el conocimiento que el médico familiar tenía del tema de la violencia hacia la mujer y de la mencionada ley, así como de los métodos y herramientas de atención y prevención para estos casos particulares, era insuficiente
