BACKGROUND: Neonatal purpura fulminans due to congenital protein C deficiency is a rare disorder. CASE CHARACTERISTICS: A four-day-old neonate presented with multiple necrotic skin lesions with abnormal coagulation profile. INTERVENTION AND OUTCOME: Skin lesions responded to repeated plasma transfusions but the neonate developed bilateral retinal detachment. A novel homozygous PROC gene mutation was noted in the neonate. MESSAGE: Molecular diagnosis and prenatal counseling in neonatal purpura fulminans are vital considering the poor outcome...

We report on the case of fatal "purpura fulminans" caused by Neisseria meningitidis W135 that occurred in a young French soldier vaccinated a few months earlier with the tetravalent conjugate vaccine ACYW135. Biological investigations revealed adequate titers of postvaccination antibodies against serogroups A, C, and W135 and led to the post-mortem diagnosis of a complete C7 complement deficiency. Late complement component deficiency is a well-known risk factor of meningococcal diseases, but usually exposes to recurrent mild infections, whereas severe invasive meningococcal diseases are more likely to occur among properdin-deficient patients...

Purpura fulminans (PF) is a life-threatening syndrome comprising progressive hemorrhagic necrosis due to disseminated intravascular coagulation and dermal vascular thrombosis that leads to purpura and tissue necrosis. Various therapies have been used to arrest the progression of this disease, however, there is no established treatment because of the variety of underlying causes. We herein present an adult case of PF associated with leukocytoclastic vasculitis triggered by antibiotic (levofloxacin) intake. As a result of our rapid and accurate identification of the underlying cause, corticosteroid therapy successfully repressed the inflammatory process...

Genetic risk factors predispose to thrombophilia and play the most important etiopathogenic role in venous thromboembolism (VTE) in people younger than 50 years old. At least one inherited risk factor could be found in about half of the cases with a first episode of idiopathic VTE.Roughly, genetic risk factors are classified into two main categories: loss of function mutations (such as deficiencies of antithrombin, protein C, protein S) and gain of function mutations, (such as prothrombin mutation G20210A, factor V Leiden)...

Asplenic patients are at increased risk for sepsis and fulminant infection. Sepsis in these patients is typically secondary to encapsulated bacteria, with Streptococcus pneumoniae being the most frequent pathogen. Rare complications of severe sepsis include purpura fulminans and bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome). We present the case of a 36-year-old woman, healthy except for splenectomy years prior for idiopathic thrombocytopenic purpura treatment, who presented with fever. Upon presentation to our hospital, three hours after symptoms onset, she had purpura fulminans and shock...

Physical, non-painful processes guide the scar reshaping in children in order to prevent growth anomalies due to cutaneous shrinkage. The objective of the surgical treatment, coordinated with the reeducation care, is to improve the physical abilities of the skin, to restore the function and avoid the deformations. Reeducation uses various techniques (i.e. sensitive-motility, massage and mobilizations) with or without physical agent (water, aspiration and touch-drive technique). Posture and positioning rely on the small or major aids, from orthosis to prosthesis...

UNLABELLED: Neisseria meningitidis is a leading cause of bacterial meningitis and septicemia, affecting infants and adults worldwide. N. meningitidis is also a common inhabitant of the human nasopharynx and, as such, is highly adapted to its niche. During bacteremia, N. meningitidis gains access to the blood compartment, where it adheres to endothelial cells of blood vessels and causes dramatic vascular damage. Colonization of the nasopharyngeal niche and communication with the different human cell types is a major issue of the N...

INTRODUCTION: Rickettsial infections are re-emerging in the Indian subcontinent, especially among children. Understanding geographical and clinical epidemiology will facilitate early diagnosis and management. METHODOLOGY: Children aged <18yrs hospitalized with clinically-diagnosed rickettsial fever were reviewed retrospectively. Frequency distributions and odds ratios were calculated from tabulated data. RESULTS: Among 262 children hospitalized between January 2008-December 2012, median age was five years, and 61% were male children...

Anticoagulants are the cornerstone of treatment of venous thromboembolism associated with various medical conditions and surgical procedures. They act on different steps of the coagulation pathway and are broadly categorized into heparins, vitamin K antagonists, and inhibitors of thrombin and factor Xa. The classification is evolving as newer and better oral and parenteral anticoagulants are being added. Anticoagulants in dermatology are important not only for their therapeutic application in cutaneous thrombotic dermatoses such as livedoid vasculitis, purpura fulminans, superficial and deep venous thrombosis and others but also for their use in non-thrombotic dermatoses such as lichen planus, recurrent oral aphthosis, chronic urticaria and several others...

A 75-year-old woman was admitted into the intensive care unit, with severe sepsis and renal failure. She developed purpura fulminans (PF) of bilateral upper and lower extremities along with gangrene on the tips of her fingers and toes. Blood cultures confirmed Pasteurella multocida as the causative organism. Despite aggressive supportive measures, the patient remained dependent on high doses of vasopressors and the gangrene progressed. She ultimately succumbed to her underlying severe sepsis. PF is a rare and fatal dermatological emergency commonly seen in children, but it also occurs in adults...

Purpura fulminans is a pediatric life-threatening emergency with a significant mortality, combining: septic shock, extensive purpuric lesions and disseminated intravascular coagulation. The most frequent bacterial pathogen is the meningococcus. The medical management includes antibiotics, corticoids, vascular filling and catecholamines. Purpura fulminans is characterized by the extent of hemorrhagic and mainly thrombotic lesions, attributed to the alteration in the vascular endothelium functions. Damage of soft tissues combines large necrotic areas and more or less extensive distal ischemic lesions...

Complement system is a part of innate immunity, its main function is to protect human from bacterial infection. As genetic disorders, complement deficiencies are often diagnosed in pediatric population. However, complement deficiencies can also be revealed in adults but have been poorly investigated. Herein, we describe a case series of infections revealing complement deficiency in adults to study clinical spectrum and management of complement deficiencies.A nationwide retrospective study was conducted in French university and general hospitals in departments of internal medicine, infectious diseases enrolling patients older than 15 years old who had presented at least one infection leading to a complement deficiency diagnosis...

Subcutaneous (SC) protein C (PC) was used in a child with purpura fulminans secondary to severe congenital PC deficiency. For maintenance, PC 80-120 IU/kg, given over 60-90 min SC Q48hr, has been successful as a home therapy for more than 3 years. The treatment was monitored by measuring trough PC chromogenic activity (target ≥15%) and D-dimer levels. No change in clinical course was appreciated after discontinuing enoxaparin (and leaving the patient on prophylactic PC replacement alone). A significant discrepancy between clotting-based and chromogenic-based PC activity is shown...

REVIEW
Viviana Bacciedoni, Myriam Attie, Hugo Donato
The incidence of thrombosis is higher among newborn infants than in any other stage of pediatric development. This fact is the consequence of labile characteristics of the neonatal hemostatic system, in addition to exposure to multiple risk factors and the wide use of vascular catheters. Venous thromboses, which mainly affect the limbs, the right atrium and renal veins, are more frequently seen than arterial thromboses. A stroke may be caused by the occlusion of the arterial flow entering the brain or by occlusion of its venous drainage system...
