Theta-Beta (T / B) ratio of the quantified electroencephalogram (EEGQ) in patients with attention deficit hyperactivity disorder (ADHD) constitutes a characteristic EEG variable of the primary disorder with an overall accuracy of 89%. The objective of this study was to measure the T/B ratio in a sample of patients with ADHD and the effects of the treatment with psychostimulants and non-psychostimulants on the T/B ratio. The sample consisted of 85 children between 6 and 18 years (68 males and 17 females) with the diagnosis of the inattentive and combined subtype of ADHD, according to the criteria of the DSM-V. ⋯ The reduction of non-psychostimulants was not significant. In conclusion, we confirmed the high T/B ratio in patients with ADHD. Psychostimulant drugs decrease the elevated T/B ratio in patients with ADHD after 6 months of treatment.

Case Reports
[Necrotizing tracheobronchitis due to invasive aspergillosis in an immunocompetent patient].
Aspergillus tracheobronchitis is a rare form of invasive aspergillosis reported exceptionally in the immunocompetent patient. Its diagnosis is difficult, and the treatments proposed so far are of little effectiveness, all of which constitute a real problem for the health team. We present the case of an immunocompetent 28 years old woman, with no epidemiological background, who developed necrotizing tracheobronchitis due to invasive aspergillosis and received voriconazole with local instillation by bronchoscopy with a good response.

Case Reports
[Mechanical fragmentation and catheter-guided thrombolysis in intermediate risk pulmonary embolism].
Acute pulmonary thromboembolism remains a significant cause of morbidity and mortality worldwide. Its diagnosis, risk stratification and early treatment are essential. The mainstay of treatment is anticoagulation. ⋯ In the intermediate-risk patients (evidence of right ventricular failure, without hemodynamic decompensation), the risk-benefit relationship of thrombolytic treatment is more balanced, so the choice is controversial. Mechanical fragmentation with catheter-directed thrombolysis is an alternative with potential benefits. We present two cases of intermediate-risk acute pulmonary thromboembolism to whom mechanical fragmentation and catheter-directed thrombolysis was applied.

There are numerous reports of incidental findings of thyroglossal duct remnants (TGDR) after total thyroidectomy, but its implication on the outcome of patients with differentiated thyroid cancer (DTC) is unknown. The aim of this study was to determine the frequency of TGDR detected by ultrasonography after total thyroidectomy in patients with DTC and to evaluate the impact of this finding on the response to treatment. A total of 377 records of patients with DTC who received total thyroidectomy between January 1994 and January 2017 were reviewed. ⋯ The prevalence of this condition seems to be rare. However, the appearance of a cystic mass during the follow-up of a patient with DTC cancer could be confused with metastatic disease. The diagnosis of TGDR seems not to have an impact on the response to treatment.

Case Reports
[Rapidly progressive dementia due to neurosyphilis (general paralysis). A treatable case of dementia].
Rapidly progressive dementias are conditions of impairment in more than one cognitive domain with functional compromise that progress in less than 1 to 2 years; and neurosyphilis is one of the etiologies. Syphilis is a chronic bacterial infection that causes a series of highly variable clinical conditions during the first 2 to 3 years, followed by a prolonged latent stage that can progress to a tertiary infection stage. After a period of years, or even decades, a third of people with untreated latent syphilis will have clinical manifestations of tertiary syphilis such as neurosyphilis. ⋯ Neuroimaging showed severe cerebral atrophy; serum and cerebrospinal fluid (CSF) reactive VDRL, in addition to a slight increase in CSF proteins. The diagnosis of late neurosyphilis was made and treated with crystalline penicillin G 1 400 000 IU every 4 h for 14 days with an excellent response. Our case allows us to reflect on the importance of requesting diagnostic studies of syphilis in young patients who present a rapidly evolving dementia, since this disease has a treatment that can partially or totally reverse the symptoms.
