Review
Levamisole exposure in cocaine users is a well-recognized cause of retiform purpura, a distinctive net-like maculopapular patch. Prolonged exposure to levamisole can lead to a serious systemic syndrome known as levamisole-induced vasculitis, most commonly involving the kidneys and lungs. More recently, retiform purpura has been observed in patients with the novel coronavirus disease of 2019 (COVID-19). Due to their overlapping dermatologic and systemic manifestations, levamisole-induced and COVID-19-induced retiform purpura may mimic one another in clinical presentation. The possibility that patients may present with one or both syndromes creates a diagnostic challenge. This review of levamisole-induced and COVID-19-induced retiform purpura highlights their corresponding and distinctive features. Additionally, we propose a unique staging system for levamisole-induced retiform purpura that may be valid for future classification of COVID-19-induced retiform purpura.

Review
Febrile seizures, which are relatively common in young children, are often triggered by an infection and resolve quickly. Prompt presentation to a pediatric department is mandatory after any first seizure and every time for children ≤ 12 months. Central nervous system (CNS) diseases in childhood are able to cause seizures or other neurological disorders. Even the slightest suspicion of a seizure with CNS involvement must be promptly treated. In case of doubt, both an antiviral and an antibacterial treatment are started in parallel, which can be stopped after detecting the pathogen. Lumbar puncture is strictly indicated unless there are contraindications. Meningococcal sepsis is a severe clinical feature comprising high fever, chills and disorders of consciousness. The first skin symptoms are petechiae as a red flag sign. With progression, potentially lethal purpura fulminans may develop. Waterhouse-Friderichsen syndrome is a severe complication of acute bacterial meningitis. Lethality rate is 35%. The pediatric assessment triangle and the ABCDE algorithm help to identify critically ill children in a standardized, structured, and rapid manner.

Roll-over trauma and associated traumatic entrapments frequently result in serious polytraumatisation. In rare cases, severe extrathoracic compressions and a protracted entrapment period can lead to Perthes syndrome, also known as traumatic asphyxia. The Perthes syndrome manifests itself by a triad of craniocervical cyanosis, facial petechiae and subconjunctival haemorrhages, enabling a rapid diagnosis based on these typical clinical features. In addition, a contusion of the heart, lungs or even the liver may occur as well as neurological and other ophthalmological complications. An early identification of this condition, the elevation of the upper body to allow adequate venous drainage in addition to ensuring sufficient oxygenation are essential for optimal therapy. In general, no long-term complications are to be expected for Perthes syndrome. The stasis usually disappears completely within a few months.

PURPURA FULMINANS IN ADULT PATIENTS. Purpura fulminans is a rare life-threatening infectious disease characterized by the association of a sudden and extensive purpuric rash together with an acute circulatory failure. PF commonly affects young patients with no previous comorbidities. Neisseria meningitidis and Streptococcus pneumoniae are the leading causative bacteria. Diagnosing purpura fulminans before the apparition of the purpuric rash is challenging since prodromal symptoms are nonspecific and consistent with a "flu-like" syndrome. The clinical presentation of patients with purpura fulminans differs from that of patients with bacterial meningitis since most of the patients with purpura fulminans have no neurological impairment. Microbiological diagnosis relies on blood cultures and skin biopsy of purpuric lesions. The indication for lumbar puncture must be evaluated on a case-by-case basis because patients usually have no neurological signs but severe coagulation disorders. Treatment is no different from that of any other septic shock: antibiotic therapy with a third-generation cephalosporin as soon as the diagnosis is suspected and treatment of associated organ failures. Despite these pathogens being highly susceptible to broadly available antibiotics, the prognosis of PF is dismal with a mortality rate of 40% in the intensive care unit and a significant risk of distant sequelae in surviving patients.

Review
Immune thrombocytopenia (ITP) is a heterogeneous disease with an unpredictable course. Chronicity can develop in up to two-thirds of adults and 20-25% of children, representing a significant burden on patients' quality of life. Despite acceptable responses to treatment, precise etiology and pathophysiology phenomena driving evolution to chronicity remain undefined. We analyzed reported risk factors for chronic ITP and associated them with proposed underlying mechanisms in its pathogenesis, including bone marrow (BM) microenvironment disturbances, clinical features, and immunological markers. Their understanding has diagnostic implications, such as screening for the presence of specific antibodies or BM examination employing molecular tools, which could help predict prognosis and recognize main pathogenic pathways in each patient. Identifying these underlying mechanisms could guide the use of personalized therapies such as all-trans retinoic acid, mTor inhibitors, FcRn inhibitors, oseltamivir, and others. Further research should lead to tailored treatments and chronic course prevention, improving patients' quality of life.

Review
Pigmented purpuric dermatoses (PPD) encompass a group of chronic skin conditions characterized by the presence of petechiae, purpura, and pigmentation changes. While generally benign, these dermatoses can be persistent and aesthetically bothersome. Key clinical features include red to brownish patches with a distinctive "cayenne pepper" appearance, predominantly localized on the lower extremities, particularly the shins. Subtypes include Schamberg disease, Majocchi's disease, Gougerot-Blum disease, Ducas and Kapetanakis pigmented purpura, and lichen aureus. Diagnosis relies primarily on clinical evaluation of skin lesions, with biopsy as a confirmatory tool. Although the exact cause of PPD remains unclear, capillary fragility and red blood cell extravasation are implicated. Treatment strategies for PPD aim to alleviate symptoms, considering the generally benign and chronic nature of the condition. As there is no standardized treatment, various methods with varying efficacy are employed. After searching SCOPUS and PubMed databases, we assessed 42 original articles to present current knowledge regarding therapy of PPD. This review will compare treatment approaches specifically in Schamberg disease and other manifestations of pigmented purpuric dermatoses.

Review
Platelets play such an important role in the process of thrombosis that patients with thrombocytopenia generally have an increased risk of bleeding. However, abnormal thrombotic events can sometimes occur in patients with thrombocytopenia, which is unusual and inexplicable. The treatments for thrombocytopenia and thromboembolism are usually contradictory. This review introduces the mechanisms of thromboembolism in patients with different types of thrombocytopenia and outlines treatment recommendations for the prevention and treatment of thrombosis. According to the cause of thrombocytopenia, this article addresses four etiologies, including inherited thrombocytopenia (Myh9-related disease, ANKRD26-associated thrombocytopenia, Glanzmann thrombasthenia, Bernard-Soulier syndrome), thrombotic microangiopathy (thrombotic thrombocytopenic purpura, atypical hemolytic uremic syndrome, hemolytic uremic syndrome, Hemolysis Elevated Liver enzymes and Low Platelets syndrome, disseminated intravascular coagulation), autoimmune-related thrombocytopenia (immune thrombocytopenic purpura, antiphospholipid syndrome, systemic lupus erythematosus), and acquired thrombocytopenia (Infection-induced thrombocytopenia and drug-induced thrombocytopenia, heparin-induced thrombocytopenia). We hope to provide more evidence for clinical applications and future research.

Review
Immune thrombocytopenia (ITP) is a relatively common disorder in childhood. Although it usually achieves spontaneous remission at this age, the management of persistent or chronic ITP in children is still controversial. The aim of this article is to address current controversies related to the treatment of persistent, chronic, and refractory ITP in children, including the role of rituximab and splenectomy, as well as focusing on a new approach with thrombopoietin receptor agonists (TPO-RAs). Eltrombopag and romiplostim are safe and useful drugs for paediatric ITP. These two TPO-RAs might delay surgery and other treatments such as rituximab. However, the potential side effects described in adult patients should be considered. Paediatric patients with refractory ITP, undergoing new treatments, should be supervised in specialised centres.

Exercise-induced purpura, which has also been called "golfer's purpura," is a phenomenon that has been rarely reported in the pediatric literature. This is the first case series in which this benign vasculopathy, which is most often associated with warm weather and high-impact activity, is described. In this series, we describe 5 patients, most of whom had an erythematous purpuric rash above the sock line that extended to the knees and was associated with warm weather and prolonged activity. Exercise-induced purpura may be mistaken for Henoch-Schönlein purpura or as a manifestation of a possible systemic vasculitis. Recognition of this benign condition is vital to avoid an unnecessary workup and a costly evaluation with accompanying anxiety.

BACKGROUND
Rumpel Leede sign (RLS) is a clinical presentation observed at the extremities due to pressure applied externally. The appearance ranges from scattered pin-point rashes to an entire arm covered with petechial hemorrhage depending upon the severity. This phenomenon is relatively uncommon in clinical practice.
CASE PRESENTATION
A 64 year old female patient developed a rash in the normal skin area below the compression area on the second day of single catheter coronary angiography. The patient's rash resolved without treatment after 3 days.
CONCLUSIONS
We report a case of hypertension and hyperlipidemia with a petechial rash on the skin under the tourniquet compressed by the radial artery after coronary angiography, which is consistent with the Rumpel-Leede phenomenon. clinicians should be watchful of these symptoms.
