Pemphigus vulgaris (PV) mainly causes blistering of the skin and mucous membranes, with nail unit involvement being rare. Nail involvement may serve as an indicator of disease severity. We present a case of a 20-year-old male with PV who had both cutaneous and nail findings, with nail changes corresponding with disease severity. The patient with biopsy-confirmed PV, on prednisone and mycophenolate, presented to the emergency department with an acute flare of PV and severe mandibular pain and lymphadenopathy. At follow-up in our outpatient department, the physical examination was significant for onychomadesis and onycholysis of the fingernails. Prednisone and mycophenolate dosages were increased, and rituximab infusions were initiated. Bullae and mucosal lesions resolved on the follow-up, and nail changes improved. This case appends an unusual perspective to the limited literature on PV-associated nail changes, especially in younger patients. It advocates for meticulous history taking and physical examination and supports a correlation between nail symptoms and PV disease severity.

INTRODUCTION
Nail alterations in children are an important cause of parent anxiety and derive in multiple and unnecessary consultations. The onychomadesis corresponds to the complete and pain less detachment of the nail plate from the proximal fold. This self-resolving nail finding has been described as a late complication of hand-foot-mouth disease, a frequent viral exanthema in the pedia tric age.
OBJECTIVE
To describe a classic pediatric case of hand-foot-mouth disease with subsequent onychomadesis.
CLINICAL CASE
A 3-years-old male patient with an acute presentation of acute erythe matous perioral papulovesicles, which extend to upper extremities and hands, buttocks, thighs and feet, asymptomatic, and without compromising general condition. Skin lesions resolve completely, but after one month, he develops detachment of the nails, with subsequent complete recovery. Con clusions: The recognition of this association will allow primary care physicians to guide the parents about a benign and self-resolving process that may occur as part of the evolution of hand-foot-mouth disease, thus avoiding unnecessary anxiety, referral and treatments.

BACKGROUND
Etiology surveillance of Hand Foot and Mouth disease (HFMD) in Beijing showed that Coxsackievirus A6 (CVA6) became the major pathogen of HFMD in 2013 and 2015. In order to understand the epidemiological characteristics and clinical manifestations of CVA6-associated HFMD, a comparison study among CVA6-, EV71- (Enterovirus 71), and CVA16- (Coxsackievirus A16) associated HFMD was performed.
METHODS
Epidemiological characteristics and clinical manifestations among CVA6-, EV71- and CVA16-associated mild or severe cases were compared from 2013 to 2015. VP1 gene of CVA6 and EV71 from mild cases, severe cases were sequenced, aligned, and compared with strains from 2009 to 2015 in Beijing and strains available in GenBank. Phylogenetic tree was constructed by neighbor-joining method.
RESULTS
CVA6 became the predominant causative agent of HFMD and accounted for 35.4 and 36.9% of total positive cases in 2013 and 2015, respectively. From 2013 to 2015, a total of 305 severe cases and 7 fatal cases were reported. CVA6 and EV71 were responsible for 57.5% of the severe cases. Five out six samples from fatal cases were identified as EV71. High fever, onychomadesis, and decrustation were the typical symptoms of CVA6-associated mild HFMD. CVA6-associated severe cases were characterized by high fever with shorter duration and twitch compared with EV71-associated severe cases which were characterized by poor mental condition, abnormal pupil, and vomiting. Poor mental condition, lung wet rales, abnormal pupil, and tachycardia were the most common clinical features of fatal cases. The percentage of lymphocyte in CVA6-associated cases was significantly lower than that of EV71. High percentage of lymphocyte and low percentage of neutrophils were the typical characteristics of fatal cases. VP1 sequences between CVA6- or EV71-associated mild and severe cases were highly homologous.
CONCLUSION
CVA6 became one of the major pathogens of HFMD in 2013 and 2015 in Beijing. Epidemiological characteristics, clinical manifestations of CVA6-, EV71- and CVA16-associated cases in this study enriched the definition of HFMD caused by different pathogens and shed light to accurate diagnosis, appropriate treatment and effective prevention of HFMD.

BACKGROUND
Hand, foot, and mouth disease (HFMD) caused by coxsackievirus A6 (CV-A6) has become prevalent in many parts of the world. It is commonly referred to as atypical HFMD which more likely to present as bullous lesions. Compared with traditional HFMD, its misdiagnosis rate is relatively high, which brings difficulties to clinical diagnosis. We retrospectively analyze the clinical characteristics of children with HFMD with bullous lesions caused by CV-A6.
METHODS
The study included 68 children with atypical HFMD caused by CV-A6 who were hospitalized from 2018 to 2020. Data of the children including age, sex, month of HFMD onset, the morphologies and distribution of rashes, the details of fever, the presence or absence of onychomadesis, and laboratory test results were analyzed and compared between an infant group (<1 year), a toddler group (1-<3 years), and a preschool group (3-<6 years).
RESULTS
Of the 68 children, 67 were younger than 5 years old, with a male to female ratio of 1.62:1. The disease peaked in the period from June to September. With 75.0% of the infant group had more than three kinds of rashes; 95.0% of the preschool group had rashes in more than five locations. These differences were statistically significant (P<0.05). All children had fever. The peak fever in the toddler group was lower (P=0.033). No critical cases were observed in any of the groups. Of the 61 children who were successfully followed up, 68.9% developed onychomadesis within 2-3 weeks. The proportion of cases with abnormal liver function was 83.3%, 41.7%, and 10.0% in the infant, toddler, and preschool groups (P<0.001). The proportion of cases with increased serum creatine kinase MB isoenzyme (CK-MB) were significantly higher in the toddler group (P<0.05).
CONCLUSIONS
Atypical HFMD caused by CV-A6 infection usually occurred in children under 5 years old. The morphologies of the rashes in the infant group changed more, while the rashes in the preschool group was more widely distributed. The incidence of critical cases was low. More than half of the cases can develop onychomadesis in the recovery period. Organ damage was relatively mild in the preschool group.

OBJECTIVE
To describe various delayed cutaneous findings associated with hand, foot, and mouth disease (HFMD).
METHODS
Patients presenting with clinical features of HFMD were followed-up prospectively for a period of 3 months for the occurrence of delayed cutaneous manifestations.
RESULTS
Out of 68 patients on regular follow-up, 23 (33.8 %) showed different types of skin and nail changes following HFMD. Nineteen showed features of onychomadesis, 9 developed nail discoloration, and Beaus line was noted in 5 patients. Cutaneous desquamation was seen in 7 patients. Spontaneous re-growth of nails occurred in all cases within 12 weeks follow-up. Skin desquamation subsided by 2-4 weeks.
CONCLUSION
Delayed cutaneous findings following HFMD are common.

Cronkhite-Canada syndrome (CCS) is a rare nongenetic polyposis syndrome first reported by Cronkhite and Canada in 1955. Up to the present time, the literature consists of ∼400 cases of CCS with the majority being reported from Japan although 49 cases have been described in China.CCS is characterized by diffuse polyposis of the digestive tract in association with ectodermal changes, such as onychomadesis, alopecia, and cutaneous hyperpigmentation. The principal symptoms of CCS are diarrhea, weight loss, abdominal pain, and other gastrointestinal complications, such as protein-losing enteropathy and malnutrition.It has been traditional to consider that CCS is associated with a poor prognosis. This paper describes a relatively mild case and reviews the literature, which more recently, suggests that it may be a more benign condition that might actually be reversible with treatment.There is some evidence that infection or disturbed immunity may be involved in the pathophysiology and that targeting such abnormalities could have therapeutic potential.A strong case could be made for establishing an international case registry for this disease so that the pathophysiology, treatment, and prognosis could become much better understood.

Upper extremity allotransplantation (UEA) is the more common type of vascularized composite allotransplantation of which more than 80 patients have benefited worldwide. These allografts include - along with the skin - the nail unit, a specialized epithelial appendage which may be the target of graft rejection. We report an UEA recipient who developed, as an initial manifestation of graft rejection, onychomadesis, that is shedding of the nail plate starting from the proximal nail bed. On this occasion, we reviewed the nail changes we have observed in a series of eight patients with UEA who were grafted and followed in our hospital since 1998 (mean follow-up period of 9.75 years). We also reviewed the relevant literature reporting nail changes in UEA recipients. A brief discussion on the significance of these changes in the context of UEA is provided with emphasis on onychomadesis, a finding usually related to graft rejection in this specific setting.

RATIONALE
Thromboangiitis obliterans (TAOs, or Buerger's disease) present as a non-atherosclerotic segmental occlusive vasculitis within medium- and small-sized blood vessels. TAO frequently occurs in young adults and is associated with cigarette smoking. At present, there are no accurately defined treatments for TAO.
PATIENT CONCERNS
A 34-year-old Asian woman with a 20-year history of heavy cigarette smoking and recurrent, small, and self-limited lower limb ulcerations since adolescence, presented with persisting unhealed ulcerations on both ankles for 6 months. Her wound healing response was poor following the 2-month administration of colchicine, prednisolone, hydroxychloroquine, and mycophenolic acid.
DIAGNOSIS
The patient was diagnosed with TAO with hyperimmunoglobulin E and refractory ulcerations on her ankles.
INTERVENTIONS
The patient received monthly omalizumab (300 mg) and previous medications for 2 months and shifted to omalizumab and colchicine without mycophenolic acid and hydroxychloroquine because of onychomadesis, which was considered to be a possible adverse drug reaction.
OUTCOMES
The wounds healed almost completely. The administration of omalizumab and colchicine will be continued until they the wounds are fully healed.
LESSONS
Mycophenolic acid has a limited function in TAO treatment, especially in cases of refractory skin ulcerations. Omalizumab can be a valuable treatment option for patients with TAO and hyperimmunoglobulin E.

BACKGROUND
Nail dystrophy arises from various inflammatory dermatologic diseases. However, there have been few reports on the prevalence of nail abnormality in atopic dermatitis (AD) or on the relationship of this condition with the severity of the disease.
OBJECTIVE
This study was intended to determine the prevalence and types of nail abnormalities associated with AD and to evaluate the relation between nail abnormalities and the severity of AD.
METHODS
AD patients aged 2 to 19 who visited the outpatient clinic were thoroughly examined for nail abnormalities. Demographic information was collected and eczema area and severity index (EASI) score for severity of AD were checked.
RESULTS
A total of 235 AD patients (children and adolescents) were investigated. There were 24 (10.2%) patients with nail abnormalities: transverse groove (Beau's line) (25.0%), nail pitting (16.7%), koilonychia (16.7%), trachyonychia (12.5%), leukonychia (12.5%), brachyonychia (8.3%), melanonychia (8.3%), onychomadesis (8.3%), onychoschizia (8.3%), and onycholysis (8.3%). There was no statistically significant difference in the total EASI score associated with development of nail abnormalities (=0.236). However, when the EASI score was confined to the lower extremities, it showed a relation to the prevalence of toe nail dystrophy (odds ratio, 1.115; 95% confidence interval, 1.014~1.316; =0.030).
CONCLUSION
Nail abnormalities in AD are thought to be caused mainly by pathologic change in the nail matrix region, and the EASI score confined to lower limbs, might be used as a predictor of toe nail changes in patients with AD.

Syphilis is a sexually transmitted disease caused by the spirochetal bacteria . It can cross the blood-brain barrier within days of the infection, causing neurosyphilis and ocular syphilis at any stage of the disease. Ocular syphilis can manifest in any part of the eye but usually as posterior uveitis and pan-uveitis or various types of inflammatory or immune-mediated optic neuritis. Misdiagnosing ocular syphilis as a non-infectious disease has been reported even when seen by ophthalmologists due to the wide variety of possible presentations. In this case report, we describe a case of ocular syphilis that presented with a non-arteritic anterior ischemic optic neuropathy (NA-AION), which to our knowledge, has not been described before in the literature.
