BACKGROUND: The nail bed may epithelialize and develop dermatoglyphics after long-standing onycholysis. We have called this phenomenon the disappearing nail bed (DNB). DNB may present as a shortened or narrow nail bed. METHODS: Examination of all 20 nails was performed in each patient enrolled to the study. DNB was defined as the presence of a nail which is at least 20% shorter and/or narrower than the identical nail on the opposite hand or foot. Age, sex, and nail history were recorded...

Nail tic disorders are classic examples of overlap between the domains of dermatology and psychiatry. They are examples of body-focused repetitive behaviors in which there is an irresistible urge or impulse to perform a certain behavior. The behavior is reinforced as it results in some degree of relief and pleasure. Nail tic disorders are common, yet poorly studied and understood. The literature on nail tic disorders is relatively scarce. Common nail tics include nail biting or onychophagia, onychotillomania and the habit tic deformity...

INTRODUCTION: Carbon monoxide poisoning is a very common cause of death in accidental, suicidal, or homicidal cases throughout the world. Fingernail bed manifestation is reported in survivors of carbon monoxide poisoning. CASE PRESENTATION: A 40-year-old Caucasian woman was exposed to carbon monoxide when she was sleeping alone in her one-bedroom apartment; fortunately, the beeps from her First Alert combination smoke and carbon monoxide detector woke her and she was saved from any extensive health issues...

This paper describes a case of subgingival foreign body embedment in the form of a finger nail fragment, as a consequence of onychophagia (fingernail biting). The result was periodontal infection that was concurrent with apical pathology on an adjacent non-vital tooth. This finding complicated the diagnosis and management of this case. Although foreign body impactions are relatively rare, they should be considered in a differential diagnosis, especially when the clinician is presented with an unusual clinical picture...

Onychophagia is defined as a chronic nail biting behaviour affecting about 20-30% of the general population. However, nail biting seems to be an ignored problem in a daily clinical practice. We have analysed the influence of onychophagia on quality of life (QoL) and stigmatisation level among 339 medical students with and without nail biting. Those with onychophagia demonstrated significantly higher QoL impairment compared to the controls (p < 0.001). Subjects who had been unable to stop nail biting behaviour in the past (p < 0...

Onychophagia is defined as chronic nail biting behaviour, which usually starts during childhood. Onychotillomania results from recurrent picking and manicuring of the fingernails and/or toenails, leading to visual shortening and/or estraction of nails. The aim of this study was to assess the prevalence of onychophagia and onychotillomania in young adults, and the comorbidity of these conditions with anxiety disorders and obsessive compulsive disorders (OCD), as well as to determine factors related to these behaviours...

This study was conducted to examine the effect of a healthy nails program on nail-biting in Turkish schoolchildren. This quasi-experimental study was of pretest-posttest control group design. A total of 50 students of a primary school formed the intervention group, while 53 students from the same school formed the control group. Data were collected with a demographic form, a nail-biting follow-up form, and photographs of the fingernails. It was found that 68.9% of students were biting seven or more of their nails; 46...

This clinical report describes the diagnosis and the management of isolated-type recession defects of complex etiology in 2 healthy postorthodontic patients. The lesions were confined to 1 mandibular incisor and were associated with an abnormal buccolingual inclination of the affected tooth despite a lingual retainer made with a round stainless steel twisted wire. After careful questioning, it was determined that the recession defects were indirect effects of habitual onychophagia. The concomitant fingernail-biting habit and the lingual bonded retainer led to the indirect development of bone dehiscence and, consequently, gingival recession...

This new analysis of 194 DNA exonerations, representing 171 criminal events, examines the types of evidence and DNA testing that have been used to free the victims of wrongful conviction. The types of DNA testing used to free the innocent parallels the growth of these techniques in forensic science. Short tandem repeat (STR) analysis now prevails (70%), though Y-STR analysis (16%) and mitochondrial testing (10%) are still used when STR analysis is not feasible, and the recently developed mini-STRs have been used for exonerations since 2008 (2...

An otherwise-healthy 13-year-old girl with previously normal nails developed longitudinal pigmented bands on multiple fingernails. Physical examination revealed faintly pigmented bands on multiple fingernails and on the left fifth toenail. We believed that the cause of the pigmented bands was onychophagia-induced longitudinal melanonychia, a rare phenomenon, which emphasizes the need for dermatologists to question patients with melanonychia about their nail biting habits because they may not be forthcoming with this information...

AIM: Nail-biting is one of the most frequent deleterious oral habits in children. It can result in systemic diseases or oral traumatic lesion. This report describes a case of gingival abscess in a child due to a fingernail-biting habit. CASE DESCRIPTION: A 5-year, 6-month-old female presented gingival swelling and fistula in the primary maxillary left central and right lateral incisors as an unusual sequelae to the periodontal tissues from fingernail-biting. A periodontal curette was used to remove the fragments and to curette the area...

Injuries to oral soft-tissues can occur due to accidental, iatrogenic, and factitious traumas. Traumatic lesions, whether chemical, physical, or thermal in nature, are among the most common in the mouth. A type of physical injury to the gingival tissues is self-inflicted. Sometimes the lesions are termed gingivitis artefacta. Self-inflicted gingival injuries in children and adolescents can occur as a result of accidental trauma, premeditated infliction, or chronic habits such as fingernail biting, digit sucking, or sucking on objects such as pens, pencils or pacifiers...

This case report represents a documentation of severe envenomation by Proatheris superciliaris, a species for which no specific antivenom exists. A 27-year-old male bitten on the finger by an adult P. superciliaris developed immediate severe pain radiating up the limb and local ecchymotic features with tissue necrosis ensuing over the following 36h, requiring debridement of necrotic tissue. Approximately 72h post-envenomation jaundice and hemoglobinuria were observed, but no other clinical signs of coagulopathy or hemorrhage...

This case report presents the orthodontic treatment of a patient with Witkop syndrome, an autosomal dominant genetic disorder characterized by the absence of several teeth and abnormalities of the nails. The patient, a 6-year 4-month-old boy, was referred to our clinic for treatment of severe overjet and openbite. Radiographic and clinical evaluations showed peg-shaped maxillary lateral incisors and the congenital absence of three mandibular incisors as well as spoon-shaped fingernails. Treatment of openbite and overjet was initiated with functional appliances, and fixed orthodontic appliances were inserted at age 10 years 3 months...

This study examined characteristics associated with mildly injurious (fingernail biting, skin picking, etc.) and more injurious (cutting, burning, etc.) self-harm (SH) in an undergraduate sample (N = 280); 31% reported mildly injurious SH within the past 3 years with no more injurious SH, whereas 20% reported more injurious SH within the past 3 years. SH was not associated with significant general negative affect or history of physical or sexual abuse, although more injurious SH was associated with a history of emotional abuse...

The clinical features of nail dystrophies depend on the part of the nail that has been damaged. Due to the important functions of fingernails and toenails, any abnormality of the nail causes impaired function of the hand or foot. Moreover, the aesthetic aspect of the nail may affect employability, self-esteem, and interaction with other people. Because the nails are often difficult to treat, cosmetology may be an effective support to medical treatment. Nail cosmetics may help the patient to cope with his or her nail dystrophy while waiting for treatment to show its efficacy...
