RESUMO
BACKGROUND: Pityriasis lichenoides (PL) is a papulosquamous dermatosis affecting both children and adults, for which no standard treatment currently exists. OBJECTIVES: To characterize different treatment options and develop an evidence-based treatment algorithm for PL. METHODS: A systematic search of published literature on PL treatments was performed on 23 December 2017 via the MEDLINE, Embase, CINAHL, CENTRAL, ClinicalTrials.gov and the EU Clinical Trials Register databases. RESULTS: Of 1090 abstracts retrieved, 27 full-text articles with 502 participants were included for analysis. Seventeen of the full-text articles were retrospective cohort studies and two were randomized controlled studies. Treatment modalities included in these articles were phototherapy, antibiotics, methotrexate, pyrimethamine and trisulfapyrimidine, corticosteroids and conservative treatment. Of these treatments, phototherapy led to complete remission in the highest proportion of patients, and topical corticosteroids were found to have been trialled in the highest number of patients. CONCLUSIONS: The current literature consists almost entirely of uncontrolled studies, and none provides compelling data to support an evidence-based approach to PL treatment. Pityriasis lichenoides chronica and pityriasis lichenoides et varioliformis acuta should be distinguished in response to treatment, and definitions of response to treatment must be standardized. Additional randomized control studies with longer follow-up will help better differentiate between treatment efficacies and adverse effects.

Although intracranial pressure (ICP) is essential to guide management of patients suffering from acute brain diseases, this signal is often neglected outside the neurocritical care environment. This is mainly attributed to the intrinsic risks of the available invasive techniques, which have prevented ICP monitoring in many conditions affecting the intracranial homeostasis, from mild traumatic brain injury to liver encephalopathy. In such scenario, methods for non-invasive monitoring of ICP (nICP) could improve clinical management of these conditions. A review of the literature was performed on PUBMED using the search keywords 'Transcranial Doppler non-invasive intracranial pressure.' Transcranial Doppler (TCD) is a technique primarily aimed at assessing the cerebrovascular dynamics through the cerebral blood flow velocity (FV). Its applicability for nICP assessment emerged from observation that some TCD-derived parameters change during increase of ICP, such as the shape of FV pulse waveform or pulsatility index. Methods were grouped as: based on TCD pulsatility index; aimed at non-invasive estimation of cerebral perfusion pressure and model-based methods. Published studies present with different accuracies, with prediction abilities (AUCs) for detection of ICP ≥20 mmHg ranging from 0.62 to 0.92. This discrepancy could result from inconsistent assessment measures and application in different conditions, from traumatic brain injury to hydrocephalus and stroke. Most of the reports stress a potential advantage of TCD as it provides the possibility to monitor changes of ICP in time. Overall accuracy for TCD-based methods ranges around ±12 mmHg, with a great potential of tracing dynamical changes of ICP in time, particularly those of vasogenic nature.
