Correlations Between Cutaneous Malignant Melanoma and Other Cancers: An Ecological Study in Forty European Countries.

BACKGROUND: The presence of noncutaneous neoplasms does not seem to increase the risk of cutaneous malignant melanoma; however, it seems to be associated with the development of other hematological, brain, breast, uterine, and prostatic neoplasms. An ecological transversal study was conducted to study the geographic association between cutaneous malignant melanoma and 24 localizations of cancer in forty European countries.

METHODS: Cancer incidence rates were extracted from GLOBOCAN database of the International Agency for Research on Cancer. We analyzed the age-adjusted and gender-stratified incidence rates for different localizations of cancer in forty European countries and calculated their correlation using Pearson's correlation test.

RESULTS: In males, significant correlations were found between cutaneous malignant melanoma with testicular cancer (r = 0.83 [95% confidence interval (CI): 0.68-0.89]), myeloma (r = 0.68 [95% CI: 0.46-0.81]), prostatic carcinoma (r = 0.66 [95% CI: 0.43-0.80]), and non-Hodgkin lymphoma (NHL) (r = 0.63 [95% CI: 0.39-0.78]). In females, significant correlations were found between cutaneous malignant melanoma with breast cancer (r = 0.80 [95% CI: 0.64-0.88]), colorectal cancer (r = 0.72 [95% CI: 0.52-0.83]), and NHL (r = 0.71 [95% CI: 0.50-0.83]).

CONCLUSIONS: These correlations call to conduct new studies about the epidemiology of cancer in general and cutaneous malignant melanoma risk factors in particular.

Cutaneous Melanoma, Hodgkin's Lymphoma and non-Hodgkin's Lymphoma: Common Risk Factors?

AIM: An epidemiological cross-sectional study was conducted to evaluate the association between cutaneous melanoma, Hodgkin's lymphoma and non-Hodgkin's lymphoma in 40 European countries.

METHODS: Incidence rates were obtained from the database of the International Agency for Research of Cancer (IARC). We analyzed age-adjusted and gender-stratified incidence rates for cutaneous melanoma, Hodgkin's lymphoma and non-Hodgkin's lymphoma in 40 European countries. All European countries included had registration systems that fulfilled the quality criteria of IARC. Normal distribution of the variables was examined using Kolmorov-Smirnov test before calculating their correlations using Pearson's Correlation test.

RESULTS: In males, positive correlations were found between cutaneous melanoma, Hodgkin's lymphoma (r=0.14, p=0.38), and non-Hodgkin's lymphoma (r=0.64, p<0.001). In females, negative correlation was found between cutaneous melanoma and Hodgkin's lymphoma (r=0.28, p=0.08), however, positive correlation was found between cutaneous melanoma and non-Hodgkin's lymphoma (r=0.72, p<0.001).

CONCLUSION: Our findings raise the hypothesis about common risk factors for cutaneous melanoma and non-Hodgkin's lymphoma. New epide-miological and genetic studies are needed to identify possible common risk factors.

Burnout y Mobbing

El burnout o síndrome del quemado es un tipo especial de estrés prolongado que cursa con agotamiento emocional, frialdad en el trato con las personas y baja autoestima profesional.

Se da en trabajos sociales que implican trato con público e importantes exigencias emocionales en la relación interpersonal.

Los profesionales donde más se ha estudiado son sanitarios, docentes y policías.

El mobbing o psicoterror laboral es otro tipo de estrés prolongado que deriva de la perversión de las relaciones interpersonales en el trabajo. Se produce cuando un trabajador percibe de forma sistemática que es el objetivo de acciones negativas de otro u otros trabajadores, en una situación con dificultades para defenderse de tales actuaciones que tratan de quebrar su estado psicológico (mobbing: acoso en manada).

El objetivo del acosador(es) es someter a la víctima a su patrón de conducta o inducirle al abandono del entorno laboral.

Aunque el ataque psicológico puede provenir de un supervisor (bossing) o de subordinados (mobbing vertical ascendente), lo más frecuente es que provenga de compañeros (mobbing horizontal).

Si el acosador es una sola persona suele tener un desorden de la personalidad de tipo NARCISISTA PSICOPÁTICA y muestra hipervigilancia y control de su víctima.

En general se trata de un mediocre profesional con un historial previo de agresiones sistemáticas (psicópata organizacional). En este caso el resto de compañeros participan permitiendo su conducta por miedo (manada pasiva).

Las patologías derivadas del riesgo psicosocial de estrés, burnout o mobbing se manifiestan también en forma de cuadros ansiosodepresivos más o menos graves. Esta patología psíquica no se contempla en el cuadro de enfermedades profesionales del Real Decreto 1995/1978 pero cabe calificarla como accidente de trabajo valorando caso a caso el nexo causal entre el daño psíquico y trabajo.

Chicken Pox May Reduce Later Risk Of Brain Cancer.

Chickenpox is a highly contagious disease that affects kids and makes their parents worry a lot. On the other hand, experts believe it may bestow a positive health benefit later in life, in the form of a lowered risk of developing glioma.
