Covid-19 is a novel infectious disease whose spectrum of presentation ranges from absence of symptoms to widespread interstitial pneumonia associated with severe acute respiratory syndrome (SARS), leading to significant mortality. Given the systemic pattern of Covid-19, there are many factors that can influence patient's functional capacity after acute infection and the identification of such factors can contribute to the development of specific rehabilitation strategies. Pulmonary impairment is the primary cause of hospitalization due to Covid-19, and can progress to SARS as well as increase length of hospitalization. Moreover, cardiac involvement is observed in approximately 30% of hospitalized patients, with an increased risk of acute myocarditis, myocardial injury, and heart failure, which may compromise functional capacity in the long-term. Thromboembolic complications have also been reported in some patients with Covid-19 and are associated with a poor prognosis. Musculoskeletal complications may result from long periods of hospitalization and immobility, and can include fatigue, muscle weakness and polyneuropathy. Studies that address the functional capacity of patients after Covid-19 infection are still scarce. However, based on knowledge from the multiple systemic complications associated with Covid-19, it is reasonable to suggest that most patients, especially those who underwent prolonged hospitalization, will need a multiprofessional rehabilitation program. Further studies are needed to evaluate the functional impact and the rehabilitation strategies for patients affected by Covid-19.

Natural myocardial markers, or speckles, originated from constructive and destructive interference of ultrasound in the tissues may provide early diagnosis of myocardial changes and be used in the prediction of some cardiac events. Due to its relatively temporal stability, speckles can be tracked by dedicated software along the cardiac cycle, enabling the analysis of the systolic and diastolic function. They are identified by either conventional 2D grey scale and by 3D echo, conferring independence of the insonation angle, thus allowing assessment of cardiac mechanics in the three spatial planes: longitudinal, circumferential, and radial. The purposes of the present paper are: to discuss the role and the meaning of cardiac strain obtained by speckle tracking during the evaluation of cardiac physiology and to discuss clinical applications of this novel echocardiographic technology.

The low socioeconomic status and the physical limitations imposed by the disease presented an important impact on the QoL reduction among CD patients, especially on environment and physical domains. Strategies to improve QoL among CD patients should be tailored and consider many different variables to maximise improvements not only of patients' physical but also of their mental health.

Introduction Chronic cutaneous lupus erythematosus (CCLE) usually presents as characteristic erythematous patches and infiltrated coin-shaped plaques. However, there are some atypical clinical variants that may mimic other dermatological conditions. Haroon et al. reported in 1972 an unusual presentation of CCLE with hypertrophic follicular scars seen in acne vulgaris. Acneiform presentation is one of the most rarely reported and one of the most confusing, as it resembles a very common inflammatory skin disease. A brief review of the literature using PubMed found only nine other reports. Case report A 32-year-old woman presented with two-year pruritic infiltrated acneiform and comedonal eruption on the right chin treated as acne with isotretinoin without improvement. On examination the patient presented with erythematous-infiltrated plaque, papules, open comedones, pitting scars and hypopigmented atrophic scars on the right chin area and scalp hair loss. An incisional skin biopsy on the chin and scalp lesions was performed and the anatomopathological and immunofluorescence exam showed findings that are consistent with CCLE. Additional tests ruled out systemic involvement. The patient was treated with prednisone and chloroquine diphosphate with great improvement. After four years the lesion is stable, with some scarring. Discussion In a literature review we found nine other cases of acneiform presentation of lupus erythematosus: Three cases were systemic lupus erythematosus (SLE) and seven others were diagnosed as CCLE (including our patient). All three patients who had SLE tested positive for antinuclear antibodies (ANA), and only one patient with CCLE, had a low titer of positive ANA (1:80). Ages varied from 24 to 60 years old, with a median of 32 years old, the same as our patient's age and consistent with the literature. Seven were females and three were males, with a ratio of 2.3:1. Most cases, such as our patient, showed acneiform lesions mainly on the face, a common site of typical CCLE. The present case and literature review illustrates the need to expand the differential diagnosis of atypical acneiform and comedonal lesions. CCLE should be considered especially in a localized lesion, which can be itchy and does not improve with conventional treatment for acne vulgaris.

Despite being an ancient disease, leprosy remains a public health problem in several countries - particularly in India, Brazil and Indonesia. The current operational guidelines emphasize the evaluation of disability from the time of diagnosis and stipulate as fundamental principles for disease control: early detection and proper treatment. Continued efforts are needed to establish and improve quality leprosy services. A qualified primary care network that is integrated into specialized service and the development of educational activities are part of the arsenal in the fight against the disease, considered neglected and stigmatizing.
