Summary
Hand-foot-mouth disease (HFMD) can cause onychomadesis (nail loss) in children, often weeks after the initial viral infection. This study details an outbreak in Valladolid, Spain, highlighting the need for increased awareness of this post-viral complication.
Area of Science:
- Pediatric Dermatology
- Infectious Diseases
- Epidemiology
Context:
- An onychomadesis outbreak linked to Hand-Foot-Mouth Disease (HFMD) occurred in Valencia, Spain, in 2008, affecting over 200 individuals, primarily children.
- This was the first documented global outbreak of this specific association.
- This report presents sixteen cases of post-viral onychomadesis in Valladolid.
Purpose:
- To describe the clinical and epidemiological characteristics of post-viral onychomadesis cases following Hand-Foot-Mouth Disease in Valladolid.
- To compare the findings with a previous outbreak in Valencia.
- To emphasize the potential underdiagnosis of this condition.
Summary:
- Between November 2008 and February 2009, sixteen individuals (15 children, 1 mother) in Valladolid presented with onychomadesis.
- Eleven patients were diagnosed with HFMD within a single month across two nurseries.
- In 60% of cases, HFMD was diagnosed 3-12 weeks prior, with six patients experiencing fever. Nail changes were temporary, with regrowth in 1-4 months.
Impact:
- The findings suggest that the association between HFMD and onychomadesis may be underestimated due to lack of awareness and diagnostic delays.
- Understanding this link is crucial for pediatricians and public health officials to recognize and manage post-viral nail abnormalities.
- This study contributes to the literature on viral exanthems and their dermatological sequelae in children.

01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
