[Factors associated with an unfavorable evolution in patients diagnosed with COVID-19 and followed up in primary care in 2020].

Aim: To know the factors associated with an unfavorable evolution (UE) of patients diagnosed with COVID-19 with total or partial follow-up in primary care.

Design: A case series.

Setting: Urban health center.

Erythroderma and Chronic Lichenification Due to Metformin.

Unlabelled: We present the case of a 62-year-old man with a 4-year history of pruritus and erythroderma. The patient had been taking metformin for 5 years, so after contact allergies, contact with toxic products, and autoimmune diseases were ruled out, the condition was treated as erythroderma secondary to metformin. A skin biopsy subsequently confirmed the diagnosis and lichenification of some areas of the patient's skin.

Food-induced IgA Vasculitis (Henoch-Schönlein Purpura).

Unlabelled: Immunoglobulin A (IgA) vasculitis is a rare entity in adults. It can be triggered by allergens such as drugs, food, or insect bites. We present a case of an adult male with a cutaneous IgA vasculitis of palpable purpura after eating canned sardines.

Fever of Unknown Origin: Don't Forget Kala-Azar Even in Europe.

Unlabelled: We present the case of a 70-year-old male patient with fever of unknown origin after a long period of convalescence from a previous admission to a chronic care hospital. During the admission, multiple combinations of antibiotic and antifungal treatments were prescribed, but with persistent fever and, eventually, neutropenia (200 lymphocytes, 0 neutrophils). Given the suspicion of infection at bone marrow level, a biopsy was performed as was serology of , both diagnostic determinations.

[Neonatal screening of hemoglobinopathies and G6PD deficiency in Catalonia (Spain). Molecular study of sickle cell disease associated with alpha thalassemia and G6PD deficiency].

Background And Objective: The prevalence of hemoglobinopathies and glucose-6-phosphate dehidrogenase (G6PD) deficiency in the Catalan neonatal population is increasing due to immigration. Coinheritance of more than a single RBC genetic defect is becoming more frequent and diagnostic pitfalls are also increasing. We intended to demonstrate the need to perform an early diagnosis of sickle cell disease (SCD) by means of neonatal screening, to establish the prevalence of SCD associated with alpha thalassemia and G6PD deficiency and to identify genotypes associated with sickle cell disease and G6PD deficiency.
