question:
The overlap between symptoms of PTSD and MDD is substantial. PTSD symptoms arise after a traumatic experience and the trauma is present in all of the diagnostic clusters. In individuals who have experienced a trauma a long time before, it is difficult to establish the exact moment of onset of their symptoms in relation to the trauma suffered. We proposed to raise awareness among operators who may encounter this problem, with the aim of providing them with valuable help in order to achieve a correct differential diagnosis. A sample of subjects suffering from PTSD without comorbidity was assessed to confirm the diagnosis and the severity of post-traumatic symptoms. The Kruskal-Wallis test was used to compare any modifications in the parameters analyzed through the Davidson Trauma Scale with the presence and severity of depressive symptoms as evaluated by the Hamilton-D scale. Half of the PSTD patients recruited showed values of HAM-D > 18, although an active Major Depressive Episode was clinically excluded. Symptom of "numbing", despite being different from the apathy experienced in depression, is identified as a depressive symptom by the HAM-D. Giving prevalence to depressive symptoms may be misleading for diagnosis and may ultimately result in inappropriate treatment.
answer:
Symptoms of which disorder are evaluated with the Davidson Trauma Scale?

question:
The nationwide prevalence of latent tuberculosis infection (LTBI) in Italian patients with psoriasis has never been investigated. To estimate the nationwide prevalence of LTBI in Italian patients with psoriasis who are candidates for systemic treatment. Data were obtained from the Psocare Registry on those patients (n=4946) with age >18years, systemic treatment at entry specified and tuberculin skin test (TST) performed according to the Mantoux method. LTBI diagnosis was based on a positive TST result in the absence of any clinical, radiological or microbiological evidence of active tuberculosis. Latent tuberculosis infection was diagnosed in 83% of patients with psoriasis (409 of 4946). The prevalence of LTBI was lower in patients on biologics than in those on conventional systemic treatments, ranging from 43% (19 of 444) of patients on adalimumab to 31% (eight of 26) of those on psoralen-ultraviolet A (P<005). Independent factors associated with LTBI were male sex [odds ratio (OR) 130, 95% confidence interval (CI) 104-162; P=002], age over 55years (OR 293, 95% CI 218-393; P<0001) and being entered into a conventional treatment (OR 383, 95% CI 310-474; P<0001). Positive history of tuberculosis was seen in 1% of patients (n=49). The nationwide prevalence of LTBI in Italian patients with psoriasis candidate to systemic treatment is high, and screening is recommended prior to biological treatment.
answer:
The Mantoux test detects what latent infection/disease?

question:
A single soldier arriving in Mexico in 1520 was carrying smallpox and thus initiated the devastating plagues that swept through the native populations of the Americas. The European diseases that ravaged the indigenous inhabitants of the Americas also severely affected the various Maya groups of Peten. It is estimated that there were approximately 30,000 Ch'ol and Ch'olti' Maya in western Peten at the start of the 16th century. Between 1559 and 1721 they were devastated by a combination of disease, war and enforced relocations. When Nojpeten fell in 1696 there were approximately 60,000 Maya living around Lake Peten Itza, including a considerable number of refugees from other areas. It is estimated that 88% of the inhabitants died during the first decade of colonial rule because of disease and war. Although disease was responsible for the majority of deaths, internecine warfare between rival Maya groups and Spanish expeditions also took their toll.
answer:
Which killed more inhabitants, disease or war?
