    This randomized, investigator-masked study compared the remanence on the nail surface of commercially available antimycotic nail lacquers containing amorolfine, ciclopirox and tioconazole. The lacquers, to which a coloring agent was added, were applied randomly to the left and right thumbnails and great toenails of 10 healthy volunteers. Volunteers were asked to wash their hands under standardized conditions at 30, 60 and 90 min after product application and to take at least one shower during the study. Photographs were taken immediately after drug application and at 30, 60 and 90 min, i.e., immediately after each hand washing, and then at 8 and 24 h. Photographs of treated toenails were taken at 0, 8 and 24 h. Photographic image analysis allowed automatic calculation of the proportion of nail surface remaining covered by the different nail lacquers over time and after washing. In addition, clinical visual assessment was made to determine the degree of the nail surface covered by the nail lacquers over time. It was demonstrated that at 24 h after product application, remanence of amorolfine nail lacquer on the thumbnails was significantly higher than that of ciclopirox (p < 0.05) and that of tioconazole on the thumb- and toenails at each time point up to 8 h after product application (all p < 0.05). Clinical observation showed that 30 min after application, the tioconazole nail lacquer had still had not completely dried. Amorolfine nail lacquer was shown to be more resistant than ciclopirox and tioconazole nail lacquers to chemical trauma from soaps and to mechanical aggressions from the immediate nail environment.

    One of the pre-requisite for a successful topical antifungal drug indicated for onychomycosis is its bioavailability into the nail unit for achieving fungal eradication and clinical benefit. The aim of this study was to compare in vitro permeation/penetration through and into human nails of amorolfine (MRF) from a 5% anhydrous commercial formulation (Loceryl®) and ciclopirox (CPX) from the 8% aqueous formulation in hydroxypropyl chitosan (HPCH) technology (Onytec®). The ability of the active ingredient to reach efficacious concentrations to inhibit nail pathogens was also evaluated. The amounts of drug permeated and retained in human healthy nails were determined using a suitably modified diffusion apparatus. HPLC analysis of the samples was performed. The HPCH-based CPX formulation demonstrated an efficient penetration into and permeation through the nail plates. Conversely, Loceryl® produced an amount of MRF permeated through and penetrated into the human toenails significantly lower than CPX. The evaluation of the efficacy index showed a higher potential efficacy of Onytec® with respect to Loceryl® on nail pathogens. The present work not only reinforced the previous results on different experimental substrates, but pointed out the superiority of HPCH-based Onytec® formulation containing CPX with respect to Loceryl® commercial product with MRF, both in terms of higher permeation through and penetration into the human nail, and for the efficacy towards the most common ungual pathogens.

    Norway spruce (Picea abies) produces resin to protect against decomposition by microbial pathogens. In vitro tests have shown that spruce resin has antifungal properties against dermatophytes known to cause nearly 90% of onychomycosis in humans. To confirm previous in vivo observations that a topical resin lacquer provides mycological and clinical efficacy, and to compare this lacquer with topical amorolfine hydrochloride lacquer and systemic terbinafine for treating dermatophyte toenail onychomycosis. In this prospective, randomized, controlled, investigator-blinded study, 73 patients with onychomycosis were randomized to receive topical 30% resin lacquer once daily for 9 months, topical 5% amorolfine lacquer once weekly for 9 months, or 250 mg oral terbinafine once daily for 3 months. The primary outcome measure was complete mycological cure at 10 months. Secondary outcomes were clinical efficacy, cost-effectiveness and patient compliance. At 10 months, complete mycological cure rates with the resin, amorolfine and terbinafine treatments were 13% [95% confidence interval (CI) 0-28], 8% (95% CI 0-19) and 56% (95% CI 35-77), respectively (P ≤ 0·002). At 10 months, clinical responses were complete in four patients (16%) treated with terbinafine, and partial in seven (30%), seven (28%) and nine (36%) patients treated with resin, amorolfine and terbinafine, respectively (P Resin, amorolfine and terbinafine treatments cost €41·6, €56·3 and €52·1, respectively, per patient (P resin lacquer and topical 5% amorolfine lacquer provided similar efficacy for treating dermatophyte toenail onychomycosis. However, orally administered terbinafine was significantly more effective in terms of mycological cure and clinical outcome than either topical therapy at the 10-month follow-up. © 2015 British Association of Dermatologists.

    Onychomycosis constitutes the most common fungal infection of the nail (skin beneath the nail bed) that affects the finger as well as toe nails. It is an infection that is initiated by yeasts, dermatophytes, and nondermatophyte molds. Nail lacquers are topical solutions intended only for use on fingernails as well as toenails and have been found to be useful in the treatment of onychomycosis. Thus, in the present review an attempt has been made to focus on the treatment aspects of onychomycosis and the ungual delivery of antifungals via nail lacquer. Several patents issued on nail lacquer till date have also been discussed. Penetration efficiency was assessed by several researchers across the human nail plate to investigate the potentiality of nail lacquer based formulations. Various clinical trials have also been conducted in order to evaluate the safety and efficacy of nail lacquers in delivering antifungal agents. Thus, it can be concluded that nail lacquer based preparations are efficacious and stable formulations. These possess tremendous potential for clinical topical application to the nail bed in the treatment of onychomycosis. PMID:27123362

    Onychomycosis is a prevailing disease caused by fungal infection of nails that mostly affects athletes and the elderly. Ciclopirox is approved by the US Food and Drug Administration for the topical treatment of onychomycosis. However, the desired penetration of ciclopirox into the nail bed has not been achieved via topical application for efficient treatment. Therefore, the main aim of this study was to enhance ciclopirox permeation and retention in nail by the development of a new nail lacquer formulation. We screened the effects of different solvents, alkalizing agents, and permeation enhancers on the permeation of bovine hooves by ciclopirox and its retention in human nail clippings. The results suggest that isopropyl alcohol, potassium hydroxide, and urea as the solvent, alkalizing agent, and permeation enhancer, respectively, improved the permeation of the ciclopirox nail lacquer formulation the most with high flux rates. Comparison of the final formulation and marketed product revealed enhanced retention of ciclopirox from our developed formulation in human nail clippings. Therefore, our newly developed nail lacquer may be a potentially effective formulation for the treatment of onychomycosis in humans.

    Although topical antifungal therapies for treating onychomycosis are available, the cure rate is unsatisfactorily low with a simultaneously high risk of recurrence. One reason might be the formation of dormant fungal cells by the pathogen, known as spores, which can survive in the affected nail keratin, thereby evading the effect of antifungal drugs. In this in vitro study, the ability of amorolfine and four other antimycotics (ciclopirox, bifonazole, terbinafine and fluconazole) to kill microconidia of the dermatophyte Trichophyton rubrum, chlamydospores of the dermatophyte Epidermophyton floccosum and blastospores of the yeast Candida albicans was extensively studied as these fungi occur predominantly in onychomycosis. The effectiveness of all five antimycotics depended on the drug concentration and the incubation time: a concentration of 10-1000 times the minimum inhibitory concentration against growing hyphae cells is needed to exert a sporicidal action. Amorolfine and ciclopirox showed the same sporicidal efficacy and kinetics for all three varieties of spores. Both were more effective than fluconazole and bifonazole against microconidia and chlamydospores as well as slightly more potent against chlamydospores and blastospores than terbinafine after 4 days of incubation and at concentrations of ≥10 μg ml(-1). Finally, sporicidal activity on the tested strains was demonstrated for all five different antimycotics used for onychomycosis treatment. © 2015 Blackwell Verlag GmbH.

    Full Text Available The successful topical therapy of onychomycosis depends on effective drug release and penetration into nail, which can be achieved by using an adequately developed delivery system. This study evaluated and compared effect of film-forming polymers Eudragit RL100, Eudragit RS100, and ethyl cellulose on naftifine hydrochloride release from experimental nail lacquer formulations. Quality of formulations was evaluated by determining drying time and water resistance. Interactions between active pharmaceutical ingredient and excipients were investigated using microcalorimetry and FT-IR. Optimization of nail lacquer formulations was performed by naftifine hydrochloride release testing. Release of naftifine hydrochloride increased with increasing concentration of Eudragit RL100. Plasticizer triacetin affected the release of naftifine hydrochloride, when Eudragit RS100 polymer was used. Ethyl cellulose polymer was determined to be not applicable for naftifine hydrochloride nail lacquer formulations. Two compositions of nail lacquers were optimized and could be used in further development of transungual delivery systems.

    Onychomycosis is a fungal nail infection. The development of new topical antifungal agents for the treatment of onychomycosis has focused on formulation enhancements that optimize the pharmacological characteristics required for its effective treatment. Polyurethanes (PUs) have never been used in therapeutic nail lacquers. The aim of this work has been the development of new PU-based nail lacquers with antifungal activity containing 1.0% (wt/wt) of terbinafine hydrochloride. The biocompatibility, wettability, and the prediction of the free volume in the polymeric matrix were assessed using a human keratinocytes cell line, contact angle, and Positron Annihilation Lifetime Spectroscopy determinations, respectively. The morphology of the films obtained was confirmed by scanning electron microscopy, while the nail lacquers' bioadhesion to nails was determined by mechanical tests. Viscosity, in vitro release profiles, and antifungal activity were also assessed. This study demonstrated that PU-terbinafine-based nail lacquers have good keratinocyte compatibility, good wettability properties, and adequate free volume. They formed a homogenous film after application, with suitable adhesion to the nail plate. Furthermore, the antifungal test results demonstrated that the terbinafine released from the nail lacquer Formulation A PU 19 showed activity against dermatophytes, namely Trichophyton rubrum.

    Onchomycosis is the most common nail fungal disease afflicting toes and fingers with a high recurrence rate. The disease is caused by various types of fungi ranging from dermatophyte to non-dermatophyte, making it difficult to eradicate. The present article focuses on the emergence of nail lacquers as prospective transungual delivery systems for the treatment of mild-to-moderate onchomycosis. Updates regarding emerging nail lacquers, research progress in terms of clinical studies and patents for better understanding of the disease are provided. Finally, the characterization techniques for the assessment of drug concentration in different layers of nail are reviewed. The conventional topical delivery systems have failed to improve nail adhesion and drug absorption due to the highly keratinized hydrophilic structure of nail which obstructs the passage of drugs. The surgical therapy systems are painful and invasive while systemic therapy produces serious side effects and a high degree of relapse. These issues have led to the advent of nail lacquers. Nail lacquers have an immense potential to improve nail adhesion as well as bioavailability. However, the nail barrier is still a challenge in imparting complete cure. Several novel approaches are being developed in order to offer better therapeutic action.

    P-3051 is an innovative 8% ciclopirox nail lacquer, based on hydroxypropyl chitosan (HPCH) as a film-forming agent. The authors' aim was to investigate P-3051's in vitro antifungal activity, as well as its in vitro and in vivo nail permeation. The dilution susceptibility tests performed for Trichophyton rubrum (T. rubrum) and Candida parapsilosis (C. parapsilosis) showed that the minimum inhibitory concentrations (MICs) of P-3051, as percent of ciclopirox, was for both fungi nail permeation and fungal inhibition, the authors observed that P-3051 permeated well through bovine hoof membranes and produced dose-dependent inhibitory effects on dermatophyte, yeast and mold strains. Moreover, the inhibition effects were higher than those obtained by equal amounts of the ciclopirox reference nail lacquer. P-3051 and the reference showed the same protective activity in experimental infections with strains of dermatophytes isolated from clinical samples. The amount of ciclopirox remained in cut fingernails washed six hours after in vivo application of P-3051 ranged between 18 and 35% of the applied dose. After in vitro application to cut human nails, 40-50% of the applied ciclopirox penetrated during the first six hours, independent of nails being infected or uninfected, intact or filed. In both experiments, the concentration of ciclopirox is largely higher (three to four orders of magnitude) than the MICs for nail pathogens.

    Full Text Available The dermatophytes are filamentous fungi that cause cutaneous fungal infections because they use keratin as a nutrient source. For this study the antidermatophyte activity of the extracts and derivates from leaves of Piper regnellii was analyzed. From the dichloromethane extract (EBD neolignans such as eupomatenoid-3 and eupomatenoid-5 were obtained, and it was submitted to fractionation to remove the green residue, designated as the chloroform fraction (FF. Extracts, chloroform fraction and compounds were tested against Trichophyton rubrum ATCC 28189 to determine the minimum inhibitory concentration (MIC. The chloroform fraction was incorporated to nail lacquer that was analyzed by photoacoustic spectroscopy, in vitro assay and scanning electronic microscopy. For antifungal activity in solid medium the dichloromethane extract and chloroform fraction were used. The compounds eupomatenoid-3 and eupomatenoid-5 were less active than the dichloromethane extract against T. rubrum. EBD and FF showed moderate activity in hyphal growth inhibition in solid medium and EBD did not link to ergosterol. Nail lacquer containing the chloroform fraction showed good penetration through the nail as determined by photoacoustic spectroscopy. From in vitro studies it was observed that nail lacquer concentrations above 20 mg/mL prevented the growth of fungi, but concentrations up to 2.5 inhibited the growth. Scanning electronic microscopy was used to confirm the in vitro nail lacquer activity results. The specie P. regnellii showed great antifungal activity against T. rubrum, and nail lacquer containing its chloroform fraction has great potential to treat onychomycosis caused by these microorganisms.

Aim: To confirm whether the strengthening and hardening properties of the hydroxypropyl-chitosan (HPCH nail lacquer could improve the structure of the nail plates on psoriatic nails. Materials and methods: A randomized, double-blind, placebo controlled, parallel-group trial was carried out to evaluate the efficacy and tolerability of a hydrosoluble nail lacquer containing HPCH, Equisetum arvense, and methylsulfonylmethane on nail psoriasis. The test product or a placebo was applied once daily for 24 weeks to all fingernails. Efficacy assessments were performed on the target fingernail by means of the modified Nail Psoriasis Severity Index score. A cut-off score of 4 was considered to define the clinical cure rate (ie, Cure ≤4, Failure >4. Results: After 24 weeks, the clinical cure rate showed the statistically significant superiority of the HPCH nail lacquer compared to placebo in both the intention-to-treat (Fisher's exact test, P=0.0445 and the per protocol population (Fisher's exact test, P=0.0437. This superiority was already present after 16 weeks of treatment. Moreover, the analysis of the modified Nail Psoriasis Severity Index-50 showed a statistically significant clinical improvement after 12 weeks of treatment in comparison to the results obtained after 8 weeks (Fisher's exact test, P<0.05. Conclusion: The trial showed that HPCH nail lacquer could be a new, valid, effective, and safe option for decreasing the signs of nail dystrophy in psoriatic patients. Keywords: nail psoriasis

    Full Text Available Onychomycosis constitutes the most common fungal infection of nail affecting finger and toe nails as well. Antifungals found to be effective in the treatment of onychomycosis. However, transport of oral antifungal agents exhibits more toxicity and requires longer treatment period. Medicated nail lacquers proved to cause lesser toxicity and required shorter treatment period. It provides not only finger/toe nail infection therapy and but also act as a protection for nails. Thus, the objective behind the present investigation was to develop nail lacquer for transungual delivery of tolnaftate. Its potency had been assessed by evaluating penetration efficiency across the bovine hoof membrane. Preliminary studies aided the optimization of thioglycolic acid as permeation enhancer (HEFmax 0.60 ± 0.377 and menthol as local anaesthetic. n-butanol:isopropyl alcohol with optimum drying time of 60 sec was selected as optimum solvent system. In total nine formulations were developed based on 32  full factorial design and characterized for drying time, non-volatile content, in vitro adhesion and permeation study. Based on highest desirability, F6 was selected as an optimized formulation and evaluated for viscosity, stability and antifungal activity. Optimized formulation exhibited optimum viscosity and stability for 1 month period. Better antifungal activity was observed against Candida albicans in comparison to the control formulation. Thus, it can be concluded from the investigation that nail lacquer could proved to be a better alternative for transungual delivery of tolnaftate.

    The development of a topical agent that would strengthen the nail, improve the natural barrier, and provide better drug penetration to the nail bed is needed. In this study, we examined the effects of a hydroxypropyl chitosan (HPCH)-based nail solution using a bovine hoof model. Following application of the nail solution, changes in the hardness of the hoof samples were measured using the Vickers method. Tensile and flexural strengths were tested by stretching or punching the samples, respectively. The ultrastructure was examined using scanning electron microscopy (SEM), and samples stained with periodic acid-Schiff (PAS) stain were used to determine the fungal penetration depth. The comparators included 40% urea and 70% isopropyl alcohol solutions. The HPCH nail solution increased hoof sample hardness in comparison to the untreated control sample (mean, 22.3 versus 19.4 Vickers pyramid number [HV]). Similarly, the HPCH solution increased the tensile strength (mean, 33.07 versus 28.42 MPa) and flexural strength (mean, 183.79 versus 181.20 MPa) compared to the untreated control. In contrast, the comparators had adverse effects on hardness and strength. SEM showed that the HPCH solution reduced the area of sample crumbling following abrasion compared to the untreated control (7,418 versus 17,843 pixels), and the PAS-stained images showed that the HPCH solution reduced penetration of the dermatophyte hyphae (e.g., penetration by Trichophyton mentagrophytes was nail solution may help prevent the establishment of new or recurring fungal nail infection.

    Onychomycosis is a common fungal nail disease that is difficult to treat topically due to the deep location of the infection under the densely keratinized nail plate. Keratin affinity of topical drugs is an important physicochemical property impacting therapeutic efficacy. To be effective, topical drugs must penetrate the nail bed and retain their antifungal activity within the nail matrix, both of which are adversely affected by keratin binding. We investigated these properties for efinaconazole, a new topical antifungal for onychomycosis, compared with those of the existing topical drugs ciclopirox and amorolfine. The efinaconazole free-drug concentration in keratin suspensions was 14.3%, significantly higher than the concentrations of ciclopirox and amorolfine, which were 0.7% and 1.9%, respectively (P nails into the receptor phase and also inhibited the growth of Trichophyton rubrum under the nail. In the presence of keratin, efinaconazole exhibited fungicidal activity against Trichophyton mentagrophytes comparable to that of amorolfine and superior to that of ciclopirox. In a guinea pig onychomycosis model with T. mentagrophytes infection, an efinaconazole solution significantly decreased nail fungal burden compared to that of ciclopirox and amorolfine lacquers (P nail permeability of efinaconazole and its potent fungicidal activity in the presence of keratin are related to its low keratin affinity, which may contribute to its efficacy in onychomycosis.

    Terbinafine nail solution (TNS) was developed for the treatment of onychomycosis. To assess the efficacy of TNS vs. vehicle and amorolfine 5% nail lacquer. Subjects with mild-to-moderate toe onychomycosis (25% to ≤75% nail-involvement, matrix uninvolved) were randomized to receive either TNS or vehicle in two double-blind studies, and to TNS or amorolfine in an active-controlled, open-label study. Primary endpoint was complete cure (no residual clinical involvement and negative mycology) at week 52. Secondary endpoints were mycological cure (negative mycology defined as negative KOH microscopy and negative culture) and clinical effectiveness (≤10% residual-involvement and negative mycology) at week 52. Complete cure was not different between TNS vs. vehicle and amorolfine. Mycological cure was higher with TNS vs. vehicle, as was clinical effectiveness with TNS vs. vehicle, and TNS and amorolfine were not different for secondary efficacy endpoints. Patients achieving mycological cure had a better clinical outcome, and efficacy was improved in subjects with milder disease. Post hoc analysis suggests that nail thickness is an important prognostic factor. Moreover, mycological cure may require 6 months of treatment regimen while complete cure and clinical effectiveness may be achievable only after 10 months. A simulation study suggests that longer treatment duration would have resulted in higher complete cure with TNS vs. vehicle. Study treatments were well-tolerated. Primary efficacy objectives were not met in the studies reported herein. Possible reasons for failure to achieve significant outcomes include insufficient length of treatment; stringency of primary endpoint and severity of nail involvement of study population. © 2011 The Authors.

    1) Fungal nail infection, or onychomycosis, mainly affects toenails. Infections are generally asymptomatic. Spontaneous regressions, but also complications, appear to be rare. Discomfort and cosmetic complaint are occasionally reported; 2) After a review of the literature based on the standard Prescrire procedure, we examined the diagnosis and management of fungal nail infections; 3) Clinical signs of fungal nail infections are non-specific. Alternative diagnoses include psoriasis and nail microtrauma. Nail hyperkeratosis and leukonychia are useful diagnostic pointers. Matrix involvement has important implications in the choice of treatment; 4) Detection of fungal structures by direct examination of a nail sample is strongly suggestive of fungal nail infection. In contrast, cases of negative direct examination with positive culture must be interpreted with caution, as contamination is frequent; 5) Antifungal lacquers (5% amorolfine and 8% ciclopirox) applied to the nails cure about 30% of fungal infections and sometimes cause mild irritation. There is no firm evidence that these solutions are any more effective than other topical antifungals applied daily to the affected nail. Trimming, filing or grinding the nail, in addition to these drug treatments, is likely to be beneficial, but these measures have not been evaluated; 6) Chemical nail destruction with a combination of urea and bifonazole, followed by treatment with an antifungal ointment, can be used when the nail is markedly thickened. Non-comparative trials have shown cure rates close to 70% at three months when the matrix is not involved, and 40% with matrix involvement. Drug application is inconvenient and local reactions are frequent. Surgical nail avulsion carries a risk of local infection and permanent nail dystrophy; 7) Oral terbinafine is effective in more than 50% of cases but its cutaneous, hepatic and haematological adverse effects are severe in about 1 in 2000 patients and can be life

    Full Text Available BACKGROUND: Nail psoriasis may affect up to 90% of patients with psoriasis in the course of the disease throughout their lives and it is often a therapeutic challenge to dermatologists. Topical treatments described in the literature have demonstrated variable efficacy, and unsatisfactory results have been associated to inefficient penetration of the active ingredient into the nail plate and proximal nail fold. Recently the use of clobetasol on nail lacquer vehicle has been suggested, with satisfactory results and no side effects. OBJECTIVE: To determine the efficacy and safety of clobetasol in nail lacquer vehicle in three concentrations (0.05%, 1% and 8% in patients with nail psoriasis. METHODS: Prospective, controlled, randomized pilot study in fifteen patients with nail bed and/or nail matrix psoriasis in both hands, subdivided into three groups: A(0.05% clobetasol nail lacquer, B(1% clobetasol nail lacquer and C(8% clobetasol nail lacquer. All groups used clobetasol nail lacquer on the left hand and base coat nail lacquer as control on the right, twice a week for 16 weeks. Clinical evaluation was done by photographic records and the NAPSI score of both treated and control hands, as well as modified NAPSI score of the most affected nail of the treated hand. RESULTS: Group C showed a statistically relevant clinical response compared to the other groups, reflected in the improvement of clinical parameters, of treated hand NAPSI score, when compared to the control hand, and modified NAPSI score of the most affected nail in the treated hand. CONCLUSION: The 8% clobetasol nail lacquer was effective and safe, and it can be considered a good option of topical therapy in the treatment of nail psoriasis.FUNDAMENTOS: A psoríase ungueal, de difícil manejo terapêutico, pode afetar até 90% dos portadores de psoríase no transcurso da doença, ao longo de suas vidas.

    Fungal nail infection (onychomycosis) is a prevalent disease in many areas of the world, with a high incidence approaching 23%. Available antifungals to treat the disease suffer from a number of disadvantages, necessitating the discovery of new efficacious and safe antifungals. Here, we evaluate the in vitro antifungal activity and nail penetration ability of ME1111, a novel antifungal agent, along with comparator drugs, including ciclopirox, amorolfine, terbinafine, and itraconazole. ME1111 showed potent antifungal activity against Trichophyton rubrum and Trichophyton mentagrophytes (the major etiologic agents of onychomycosis) strains isolated in Japan and reference fungal strains with an MIC range of 0.12 to 0.5 mg/liter and an MIC50 and MIC90 of 0.5 mg/liter for both. Importantly, none of the tested isolates showed an elevated ME1111 MIC. Moreover, the antifungal activity of ME1111 was minimally affected by 5% wool keratin powder in comparison to the other antifungals tested. The ME1111 solution was able to penetrate human nails and inhibit fungal growth in a dose-dependent manner according to the TurChub assay. In contrast, 8% ciclopirox and 5% amorolfine nail lacquers showed no activity under the same conditions. ME1111 demonstrated approximately 60-fold-greater selectivity in inhibition of Trichophyton spp. than of human cell lines. Our findings demonstrate that ME1111 possesses potent antidermatophyte activity, maintains this activity in the presence of keratin, and possesses excellent human nail permeability. These results suggest that ME1111 is a promising topical medication for the treatment of onychomycosis and therefore warrants further clinical evaluation.

    The treatment of onychomycosis remains problematic even though there are several potent antifungal agents available for patient use. The aim of this investigation was to understand whether the structural modifications that arise when a patient's nail become infected plates influences the permeation of drugs into the nail following topical application. It was hoped that through improving understanding of the nail barrier in the diseased state, the development of more effective topical treatments for onychomycosis could be facilitated. The permeation of three compounds with differing hydrophobicities, caffeine, terbinafine and amorolfine (clogD at pH 7.4 of -0.55, 3.72 and 4.49 respectively), was assessed across both healthy and onychomycosis infected, full thickness, human nail plate sections. Transonychial water loss (TOWL) measurements performed on the healthy and diseased nails supported previous observations that the nail behaves like a porous barrier given the lack of correlation between TOWL values with the thicker, diseased nails. The flux of the more hydrophilic caffeine was twofold greater across diseased in comparison with the healthy nails, whilst the hydrophobic molecules terbinafine and amorolfine showed no statistically significant change in their nail penetration rates. Caffeine flux across the nail was found to correlate with the TOWL measurements, though no correlation existed for the more hydrophobic drugs. These data supported the notion that the nail pores, opened up by the infection, facilitated the passage of hydrophilic molecules, whilst the keratin binding of hydrophobic molecules meant that their transport through the nail plate was unchanged. Therefore, in order to exploit the structural changes induced by nail fungal infection it would be beneficial to develop a small molecular weight, hydrophilic antifungal agent, which exhibits low levels of keratin binding.

    Full Text Available Nail dyschromias have a wide variety of presentation. There are numerous causes of discoloration of the nail affecting the nail plate, nail attachments, or the substance of the nail. The chromonychia may also be caused due to the exogenous deposition of pigments over the nail plate. Careful examination of the nail and few bed side tests may help in identifying the root cause of the nail dyschromia and many a times unravels some underlying systemic disorder too.

    In in vitro tests, natural coniferous resin from the Norway spruce (Picea abies) is strongly antifungal. In this observational study, we tested the clinical effectiveness of a lacquer composed of spruce resin for topical treatment of onychomycosis. Thirty-seven patients with clinical diagnosis of onychomycosis were enrolled into the study. All patients used topical resin lacquer treatment daily for 9 months. A mycological culture and potassium hydroxide (KOH) stain were done from nail samples in the beginning and in the end of the study. Treatment was considered effective, if a mycological culture was negative and there was an apparent clinical cure. At study entry, 20 patients (20/37; 54%; 95% CI: 38-70) had a positive mycological culture and/or positive KOH stain for dermatophytes. At study end, the result of 13 patients was negative (13/19; 68%; 95% CI: 48-89). In one case (1/14; 7%; 95% CI: 0-21) the mycological culture was initially negative, but it turned positive during the study period. By 14 compliant patients (14/32; 44%; 95% CI: 27-61), resin lacquer treatment was considered clinically effective: complete healing took place in three cases (9%) and partial healing in 11 cases (85%). The results indicate some evidence of clinical efficacy of the natural coniferous resin used for topical treatment of onychomycosis. © 2012 Blackwell Verlag GmbH.

    Full Text Available BACKGROUND: The use of topical antifungal agents in the treatment of onychomycosis is of great value in clinical practice as there are different limitations regarding the use of systemic treatment. OBJECTIVE: To evaluate the efficacy and safety of a nail lacquer formulation containing ciclopirox 8% in two different posologies: the traditional regimen (3/2/1 and a regimen of weekly use. METHODS: A blind, randomized, comparative trial which included 41 patients divided into 02 groups, with Group I using the nail lacquer once weekly and Group II using the traditional regimen (3/2/1. Both groups applied the medication for 06 months. RESULTS: The species most frequently found in groups I and II were Trichophyton rubrum (55% and 61.9% and Trichophyton mentagrophytes (30% and 19%. There was a tendency to a higher level of treatment resistance by T. mentagrophytes infection in both groups, without any predilection for sex, age, proportion of the nail affected at the beginning of the study, duration of the clinical disease and quantity of nails affected per person. Both groups had significant levels of mycological cure, clinical response and therapeutic success and there was no statistically significant difference between groups I and II (p >0.05. CONCLUSION: The nail lacquer containing ciclopirox 8% was equally effective at a weekly dose when compared to the traditional dosing (3/2/1, allowing a more comfortable regimen.FUNDAMENTOS: A utilização de antifúngicos tópicos na terapêutica da onicomicose é de grande valor na prática clínica, visto que há diferentes limitações ao uso das opções terapêuticas sistêmicas.

    Onychomycosis is a common fungal infection of the nail plate and bed that affects up to 14% of the population and can have a substantial impact on the quality of life of those affected. This study compared the onychopharmacokinetics, nail absorption, nail distribution, and nail penetration of [(14)C]-ciclopirox dissolved in novel lipid diffusion enhancers with that of a commercial ciclopirox nail lacquer using the in vitro finite dose model. The penetration rate of ciclopirox was determined by applying doses of topical formulation twice daily to human nail plates for 11 d. Drug absorption was then measured by monitoring its rate of appearance in each nail layer and in the cotton pad/nail supporting bed. After a multiple day treatment, cumulative concentrations of ciclopirox formulated with lipid enhancers in the deep nail layer and the nail bed were significantly greater than cumulative concentrations of the commercial ciclopirox lacquer (p nail can be utilized as a means of effective transungual delivery.

    Full Text Available We perform an experiment on lacquer formation with simple test device. The anti-lacquer is one of important issues to increase durability, and to improve performance in the engines because the lacquer formation cause sticking of fuel injection pump, scuffing of cylinder liners, and increase of lubricant oil consumption in the marine diesel engines. We suggest this simple test in order to save enormous experimental cost in marine diesel engines, and in order to have ease in performing the various tests. The influences of the Base Number (BN of lubricant oils and the sulfur content of fuel oils in the formation of lacquer are investigated. In order to investigate physical and chemical properties of lacquer, we perform a variety of tests such as, visual inspection, EDS. In addition, we investigate adhesion of lacquer by pull-off test quantitatively, and perform dissolution test with dilute sulfuric acid.

    The in vitro absorption of panthenol into and through the human nail was examined in this study. Panthenol, the alcohol form of pantothenic acid (vitamin B5), is believed to act as a humectant and improve the flexibility and strength of nails. A liquid nail treatment formulated with panthenol (2%) was compared to a solution of panthenol (2%) in water. Fingernail specimens were dosed daily for 7 days with either the nail treatment (non-lacquer film forming) formulation or aqueous solution with sampling performed every 24 h. Panthenol concentrations were determined in the dorsal surface, interior (by drilling and removal) and in the supporting bed under the human nail. Panthenol levels in the dorsal nail (R(2) = 0.87; P panthenol was delivered into the interior nail and supporting bed by a nail treatment formulation than from an aqueous solution. The film acts not only as a reservoir of panthenol, but also acts to increase the hydration of the nail and the thermodynamic activity of panthenol as well, thereby enhancing diffusion.

    Tinea corporis is a common superficial dermatophytosis seen in tropical countries. Newer molecules are constantly being introduced for its treatment. Topical clotrimazole is in vogue as the treatment for this condition for a long time. Amorolfine is a comparatively recently introduced drug for topical use in this condition. To assess the effectivity and safety of amorolfine 0.25% cream in patients with tinea corporis, in comparison to clotrimazole 1% cream. Patients presenting with symptoms of tinea corporis were mycologically confirmed for the presence of fungal hyphae. They were randomly divided into two groups: one group received amorolfine and the other received clotrimazole. Treatment duration was for 4 weeks and study duration was for 8 weeks. Evaluation was carried out using the standard clinical parameters on day 1, day 14, day 28 and a follow-up on day 56. Adverse effects were also recorded. Data entry was done in Excel datasheet and analyzed with Epiinfo 2002. Chi-square test and t-test were used according to the type of data. The patients of the two groups were matched at baseline in respect to their demographic profile. Analysis of collected data showed significant improvement in both the groups, suggesting that both the drugs were effective agents in tinea corporis infection. Between-groups comparison of mycological cure rate and clinical improvement showed no significant difference. Amorolfine 0.25% cream is found to be safe and effective, like clotrimazole, when used topically in tinea corporis.

    Nail infections are and will continue to be a diagnostic and therapeutic challenge to all foot physicians. Attention to basic concepts of accurate detailed history and physical examination will aid in the determination of the etiology of these infections. Following basic guidelines of incision and drainage, gram stain, soaks, and antibiotics will be the cornerstone of initial treatment of pyogenic infections. Upon resolution of the acute infection a permanent treatment plan can be constituted based on the etiology. Nail infections of mycotic nature require an understanding by both patient and doctor as to the difficulty and resistance to treatment of this problem. It is the authors' opinion that aggressive persistent treatment will provide the best long-term result when dealing with mycotic infections. This may require nail removal, local and systemic treatment as well as change in shoe environment. As we have seen and is stated throughout this text, the nail and its pathologic processes can be a mirror of systemic disease. Many times a dystrophic infected nail may be the initial clinical presentation of a much more involved disease process. It is the responsibility and duty of all foot physicians to have a total understanding of knowledge of normal and pathologic process that affect the nail plates, nail bed, and surrounding nail proper. I hope this article will stimulate the foot physician to approach the disease of the nail with a high index of suspicion and respect.

    The structure of the nail unit is complex and many dermatologists and dermatopathologists have an incomplete understanding of it. Familiarity with the anatomy and histology of this unit, however, is a key factor in improving the diagnostic yield of nail biopsy. Inflammatory or infectious conditions that affect the nail can have a marked impact on a patient's quality of life. A wide-ranging variety of tumors can also develop in this region and they may be life-threatening or require surgery that will result in functional defects. The author reviews the anatomy and histology of the nail unit as well as the basic histopathologic findings in the most common conditions affecting the nails.

    Full Text Available Oriental lacquer is a material of vegetal origin that is used in the Asian countries as a coating for the most varied kinds of religious and civil use objects. With the Portuguese arrival to the East, the Europeans started to develop a taste for the exotic and exquisite Art of Lacquer. From the 16th century onwards a lacquerware market developed with numerous lacquered objects being brought to Europe. In this work, the red lacquer from a pair of Namban stirrups was studied by Py-GC/MS (pyrolysis-gas chromatography/mass spectrometry. The results were compared with lacquer references, and the lacquer type was identified. Based on the results, the stirrups' lacquering technique and the performance of Py-CG/MS in the identification of oriental lacquers are also discussed.

    Nowadays, only crude resins are used for lacquer wares. In Myanmar lacquer ware makers have not yet used modification methods for fast drying and brightness to improve the quality as in the Japanese lacquer wares. Thus it takes about three months to season the lacquer wares. The main factor which delays the seasoning is the slow process of drying of thitsi (Myanmar lacquer), which is extracted from naturally grown Melanorrhoea usitata Wall. This paper is attempted to find ways for fast drying process. It was found that drying in the oven at 100 0 C is the suitable treatment for commercial scale production. (author)

    Nenoff, P; Paasch, U; Handrick, W

    2014-04-01

    Infections of the finger and the toe nails are most frequently caused by fungi, primarily dermatophytes. Causative agents of tinea unguium are mostly anthropophilic dermatophytes. Both in Germany, and worldwide, Trichophyton rubrum represents the main important causative agent of onychomycoses. Yeasts are isolated from fungal nail infections, both paronychia and onychomycosis far more often than generally expected. This can represent either saprophytic colonization as well as acute or chronic infection of the nail organ. The main yeasts causing nail infections are Candida parapsilosis, and Candida guilliermondii; Candida albicans is only in third place. Onychomycosis due to molds, or so called non-dermatophyte molds (NDM), are being increasingly detected. Molds as cause of an onychomycosis are considered as emerging pathogens. Fusarium species are the most common cause of NDM onychomycosis; however, rare molds like Onychocola canadensis may be found. Bacterial infections of the nails are caused by gram negative bacteria, usually Pseudomonas aeruginosa (recognizable because of green or black coloration of the nails) but also Klebsiella spp. and gram positive bacteria like Staphylococcus aureus. Treatment of onychomycosis includes application of topical antifungal agents (amorolfine, ciclopirox). If more than 50 % of the nail plate is affected or if more than three out of ten nails are affected by the fungal infection, oral treatment using terbinafine (in case of dermatophyte infection), fluconazole (for yeast infections), or alternatively itraconazole are recommended. Bacterial infections are treated topically with antiseptic agents (octenidine), and in some cases with topical antibiotics (nadifloxacin, gentamicin). Pseudomonas infections of the nail organ are treated by ciprofloxacin; other bacteria are treated according to the results of culture and sensitivity testing.

    Nan-Kai Wang

    Full Text Available OBJECTIVES: Validation of choroidal thickness and other biometrics measured by spectral domain optical coherence tomography (SD-OCT in predicting lacquer cracks formation in highly myopic eyes. METHODS: Patients with a refractive error worse than -8 diopters and moderate myopic maculopathy were recruited into two groups based on the presence or absence of lacquer cracks (36 eyes without and 33 eyes with lacquer cracks. Choroidal thickness, refractive error, and axial length were measured and subjected to receiver operating characteristic curve analysis to identify the optimal cutoff values at predicting lacquer crack formation. The width of the retinal pigment epithelium (RPE, RPE to the inner segment/outer segment line, RPE to the external limiting membrane were also measured and compared to the subfoveal choroidal thickness to assess their relationships as potential markers of lacquer crack formation. RESULTS: Lacquer crack is associated with decreased choroidal thickness, lower best-corrected visual acuity, longer axial length and higher refractive errors. Choroidal thickness has the strongest association with lacquer crack formation versus axial length and refractive error. In eyes with lacquer cracks, stellate lacquer cracks are associated with thinner choroidal thickness compared to eyes with linear lacquer cracks. Subfoveal choroidal thickness less than the width of the retinal pigment epithelium to the inner segment/outer segment line is also associated with lacquer crack formation (sensitivity 78.8%, specificity 88.3%, and accuracy 81.2%. CONCLUSIONS: This study suggests that choroidal thickness and other SD-OCT measurements could be employed clinically to predict the development and severity of lacquer cracks in patients with high myopia.

In order to obtain an in vitro index that is relevant to the clinical efficacy of topical anti-onychomycosis drugs, we profiled five topical drugs: amorolfine, ciclopirox, efinaconazole, luliconazole, and terbinafine, for their nail permeabilities, keratin affinities, and anti-dermatophytic activities in the presence of keratin. Efinaconazole and ciclopirox permeated full-thickness human nails more deeply than luliconazole. Amorolfine and terbinafine did not show any detectable permeation. The free-drug concentration of efinaconazole in a 5% human nail keratin suspension was 24.9%, which was significantly higher than those of the other drugs (1.1-3.9%. Additionally, efinaconazole was released from human nail keratin at a greater proportion than the other drugs. The MICs of the five drugs for Trichophyton rubrum were determined at various concentrations of keratin (0-20% in RPMI 1640 medium. The MICs of ciclopirox were not affected by keratin, whereas those of efinaconazole were slightly increased and those of luliconazole and terbinafine were markedly increased in the presence of 20% keratin. Efficacy coefficients were calculated using the nail permeation flux and MIC in media without or with keratin. Efinaconazole showed the highest efficacy coefficient, which was determined using MIC in media with keratin. The order of efficacy coefficients determined using MIC in keratin-containing media rather than keratin-free media was consistent with that of complete cure rates in previously reported clinical trials. The present study revealed that efficacy coefficients determined using MIC in keratin-containing media are useful for predicting the clinical efficacies of topical drugs. In order to be more effective, topical drugs have to possess higher efficacy coefficients.

    Clinical symptoms attributed to the nail apparatus and observed in cosmetology include atrophic or hypertrophic lesions, pathologic nail coloration, abnormalities of the nail surface, and disorders of the nail plate and bed junction. These symptoms may reflect pathologic processes limited to the nail apparatus or may be the consequence of a dermal or systemic disease. Even though the etiology of nail lesions is variegated, diseases of the nails are simply classified as infectious or non-infectious. The aim of this work was to present the most common diseases of the nail apparatus encountered in cosmetology. Often, nail diseases worsen the quality of life of the patient. In addition, the variegated symptomatology demonstrates that nail lesions should be viewed in a wider perspective because they often are important signs of pathologic processes taking place in the organism of the patient.

    Nanoparticles are increasingly used in paints and lacquers. Little is known of the toxicity of nanoparticles incorporated in complex matrices and released during different phases of the life cycle. DNA damaging activity and inflammogenicity of sanding dust sampled during standardised sanding of boards painted with paints with and without nanoparticles were determined 24 h after intratracheal instillation of a single dose of 54 μg in mice. Dusts from nanoparticle-containing paints and lacquers did not generate pulmonary inflammation or oxidative stress. Sanding dust from both the nanoparticle-containing and the conventional lacquer and the outdoor acrylic-based reference paint increased the level of DNA strand breaks in bronchoalveolar fluid cells. In conclusion, addition of nanoparticles to paint or lacquers did not increase the potential of sanding dust for causing inflammation, oxidative stress or DNA damage, suggesting that the paint/lacquer matrix is more important as determinant of DNA damage than the nanomaterial.

    This paper reports on work done over the past two years in our laboratory to produce X-ray optics. We also report on tests that we have made to evaluate the performance of pieces that we have produced. As we progress towards the 21st century, there is a growing need to understand fabrication techniques for grazing incidence optics. To this end we report our results of fabricating, testing, and measuring both Wolter I optics and flats. We have used the techniques of lacquer coating. We have made flats to determine our ability to coat surfaces with lacquer and gold, as well as to demonstrate reflectivity up to 40 keV. We also produced Wolter I optics nickel optics with a gold coated optical surface. Here we report and interpret results from X-ray reflectivity and Wyko profiler optical measurements. We also describe our fabrication process and provide a critique of the process and describe how we hope to further improve upon the basic technique

  16. Development of microwave absorbing materials prepared from a polymer binder including Japanese lacquer and epoxy resin

    Science.gov (United States)

    Iwamaru, T.; Katsumata, H.; Uekusa, S.; Ooyagi, H.; Ishimura, T.; Miyakoshi, T.

    Microwave absorption composites were synthesized from a poly urushiol epoxy resin (PUE) mixed with one of microwave absorbing materials; Ni-Zn ferrite, Soot, Black lead, and carbon nano tube (CNT) to investigate their microwave absorption properties. PUE binders were specially made from Japanese lacquer and epoxy resin, where Japanese lacquer has been traditionally used for bond and paint because it has excellent beauty. Japanese lacquer solidifies with oxygen contained in air's moisture, which has difficulty in making composite, but we improved Japanese lacquer's solidification properties by use of epoxy resin. We made 10 mm thickness composite samples and cut them into toroidal shape to measure permittivity, permeability, and reflection loss in frequencies ranging from 50 Hz to 20 GHz. Electric magnetic absorber's composites synthesized from a PUE binders mixed either with Soot or CNT showed significantly higher wave absorption over -27 dB than the others at frequencies around 18 GHz, although Japanese lacquer itself doesn't affect absorption. This means Japanese lacquer can be used as binder materials for microwave absorbers.

    2014-10-01

    Onychomatricoma is a rare tumor originating from the nail matrix, and, in rare conditions, from the ventral aspect of the proximal nailfold. Here we report a rare case of a 51-year-old man presenting with melanonychia mainly involving the distal nail plate. Histopathologic examination showed typical findings of onychomatricoma mainly involving the nail bed, while the nail matrix was largely uninvolved. We also identified fungal infection in a focal area of the distal nail plate. Our findings indicate that onychomatricoma can develop in the surrounding epithelial tissue of the nail unit, including the nail bed, and suggest that fungal infection may represent a secondary phenomenon of onychomatricoma. © 2014 John Wiley & Sons A/S.

    Lacquering is considered one of the most representative Asian artistic techniques. While the decorative part of lacquerwares is the lacquer itself, their substructures serve as the backbone of the object itself. Very little is known about these hidden substructures. Since lacquerwares are mostly composed of organic materials, such as urushi, wood, carbon black, and fabrics which are very X-ray transparent, standard X-ray radiography has some problems in achieving clear X-ray radiographic images. Therefore, we wanted to contribute to the understanding of the lacquer manufacturing technique by inspecting the substructures of Asian lacquerwares by means of THz time-domain imaging (THz-TDI). Three different kinds of Asian lacquerwares were examined by THz-TDI, and the outcomes have been compared with those obtained by standard X-radiography. THz-TDI provides unique information on lacquerwares substructures, aiding in the comprehension of the manufacturing technology yielding to these precious artefacts.

  5. Comparison of the antifungal efficacy of terbinafine hydrochloride and ciclopirox olamine containing formulations against the dermatophyte Trichophyton rubrum in an infected nail plate model.

    Science.gov (United States)

    Täuber, Anja; Müller-Goymann, Christel C

    2014-07-07

    Onychomycosis is a fungal infection mostly induced by dermatophytes such as Trichophyton rubrum. Due to slow nail growth, the treatment takes 3-9 months depending on the nail size and infected area. Hence, high efficacy of the active ingredient without systemic side effects is of major interest. To test the efficacy of an antifungal formulation, an appropriate in vitro model reflecting the in vivo situation as close as possible is required. In this study, a variety of antifungal formulations, i.e., commercial ones (Ciclopoli and Lamisil cream), those used in compounding pharmacies (Pentravan) as well as poloxamer 407-based systems, have been evaluated in an infected nail plate model. The active pharmaceutical ingredients (APIs) were ciclopirox olamine and terbinafine hydrochloride. The poloxamer 407-based formulations consisted of poloxamer 407, double distilled water, propylene glycol, isopropyl alcohol, medium chain triglycerides and either 1% ciclopirox olamine or 1% terbinafine hydrochloride as API, respectively. Former studies have shown high permeation rates of terbinafine hydrochloride from similar poloxamer 407-based formulations with dimethyl isosorbide instead of propylene glycol. The present contribution shows superior inhibition of T. rubrum growth from poloxamer 407-based formulations in comparison to the commercial Lamisil cream. Moreover, poloxamer 407-based formulations were equally effective as the nail lacquer Ciclopoli even though the poloxamer formulations contained only 1% of the drug instead of 8% in the marketed lacquer. Poloxamer 407-based systems containing ciclopirox olamine proved to be about as effective as similar terbinafine hydrochloride systems.

    2012-01-01

    This article provides an updated review on diagnosis and treatment of inflammatory nail disorders including psoriasis, lichen planus, trachyonychia, and autoimmune bullous disorders. Despite the significant negative repercussion of the nail psoriasis in the quality of life of patients, treatment is often not sufficiently effective. The efficacy of topical therapies is limited to nail bed psoriasis. Intralesional corticosteroid injections are extensively utilized in nail matrix psoriasis. Systemic immunosuppressant drugs such as methotrexate and cyclosporine have shown efficacy. Biologics, particularly infliximab and etanercept, have also demonstrated high efficacy in the treatment of severe nail disease. Nail matrix lichen planus can cause nail atrophy and irreversible nail scarring and requires prompt treatment with systemic steroids. There is not gold standard therapy for trachyonychia, but in most cases the nail signs improve spontaneously and treatment is not necessary. Nail changes in pemphigus and other autoimmune disorders respond promptly to systemic therapy with steroids and immunosuppressants. © 2012 Wiley Periodicals, Inc.

    Sobolewski, Piotr; Walecka, Irena; Dopytalska, Klaudia

    2017-01-01

    Nail psoriasis is considered a significant psychological and social problem causing functional impairment in affected patients. Nail changes hamper their daily and occupational activities and contribute to a worse quality of life. Almost 50% of patients with psoriasis vulgaris and up to 80% of patients with psoriatic arthritis are afflicted with nail lesions. The important correlation between psoriatic arthritis and nail changes is well established - the presence of the latter is a strong predictor of the development of arthritis. There is a broad spectrum of nail dystrophies associated with psoriasis, ranging from the common pitting, subungual hyperkeratosis and loosening of the nail plate to less frequent discolouration and splinter haemorrhages. Some of these symptoms are also observed in other nail diseases, and further diagnostics should be performed. The assessment tools NAPSI (Nail Psoriasis Severity Index), mNAPSI (Modified Nail Psoriasis Severity Index), and PNSS (Psoriasis Nail Severity Score) are most commonly used to grade the severity of nail involvement in psoriasis and enable the evaluation of therapy effectiveness. The treatment of nail psoriasis is a major clinical challenge. It should be adjusted to the extent of dermal, articular and ungual lesions. Systemic therapies of psoriasis, especially biological agents, are most likely to be effective in treating nail psoriasis. However, as their use is limited in scope and safety, topical therapy remains a mainstay, and the combination of corticosteroids and vitamin D 3 analogues is considered to be most helpful.

  16. Polymerization of Oriental Lacquer (Urushi with Epoxidized Linseed Oil as a New Reactive Diluent

    Directory of Open Access Journals (Sweden)

    Takahisa Ishimura

    2015-01-01

    Full Text Available A hybrid lacquer (HBL paint prepared by combining a natural kurome lacquer (KL paint and an amino silane reagent, for example, N-(2-aminoethyl-3-aminopropyl triethoxysilane (AATES, produced a polymerized film faster than the KL paint alone. However, the viscosity of the HBL paint was too viscous for easy handling. Addition of 10 wt% of an epoxidized linseed oil, ELO-6, with 6.4 mol% epoxidation as a reactive diluent to the HBL paint decreased the viscosity by 1/2 from 25476 mPa·s to 12841 mPa·s and improved the ease of coatability. The polymerization mechanism was elucidated by NMR measurements of extracts from the resulting polymerization films, suggesting that amino groups in the HBL paint reacted with epoxy groups of ELO-6 in the lacquer matrix, and then the complex reacted with double bonds of the urushiol side-chain by autooxidation and cross-linking reactions to give a hard polymerized film with a high quality of color and gloss. These results indicate that the addition of ELO-6 improved the polymerizability of both KL and HBL paints without decreasing the quality of the resulting films.

    The use of artificial nails (ANs) as part of nail-care cosmetics is very popular. Several side effects and complications, such as contact dermatitis and bacterial and fungal infections, have been reported in patients using ANs. Objective The purpose of this study was to identify the fungal pathogens in nail abnormalities appearing in patients with ANs. We evaluated 68 patients suffering from nail changes and paronychia, which appear after removal of ANs. Mycological samples were obtained from two sites: distal parts of the involved nail and the proximal nail fold. KOH examination and fungal culture were used for detection and identification of fungal infection. Mycological results from the distal part of the nail showed positive KOH test in 57 cases (83.8%), and culture was positive in 67 patients (98.5%). Mycological results obtained from the proximal nail fold showed positive KOH test in 36 patients (52.9%); in 36 of the cases, culture was positive. Candida spp. were the most common pathogen. Both KOH and culture results were significantly better while sampling from the distal part of the nail compared with sampling from the proximal nail fold (P = 0.0001). Onychomycosis was found to be very common in nail changes due to ANs, leading to an increased risk of transmitting microbial infections. Therefore, health care personnel and workers in the food industry should avoid using ANs.

    Full Text Available OBJECTIVE: to analyze the results from surgical intervention to treat trauma of the nail complex.METHODS: we retrospectively reviewed a series of 94 consecutive patients with trauma of the nail complex who were treated between 2000 and 2009. In 42 patients, nail bed suturing was performed. In 27 patients, nail bed suturing was performed subsequent to osteosynthesis of the distal phalanx. In 15, immediate grafting was performed, and in 10, late-stage grafting of the nail bed. The growth, size and shape of the nail were evaluated in comparison with the contralateral finger. The results were obtained by summing scores and classifying them as good, fair or poor.RESULTS: the results were considered to be good particularly in the patients who underwent nail bed suturing or nail bed suturing with osteosynthesis of the distal phalanx. Patients who underwent immediate or late-stage nail grafting had poor results.CONCLUSION: trauma of the nail complex without loss of substance presented better results than did deferred treatment for reconstruction of the nail complex.

    Full Text Available Nail biopsy is a procedure not routinely resorted to; but when indicated, it is often the only clue left for diagnosis. At such times, it pays to be conversant with it. It is an investigation that not only provides etiologic, diagnostic, and prognostic information but also aids in understanding the pathogenesis of nail diseases. It can be of therapeutic value, especially with respect to nail tumors. This article compiles the procedural techniques for nail biopsy of various types and attempts to summarize the evidence available in the literature. The objective of nail biopsy is to clinch a precise diagnosis of nail pathology with a simple and safe surgical procedure, avoiding pain or permanent nail damage. Patient selection is of utmost importance, wherein, the patient does not have typical skin lesions, yields inadequate information on routine nail investigations, and has no peripheral vascular compromise. The patient needs to be explained about the risks associated, the expected functional handicap, the time required for regrowth, a possibility of permanent nail dystrophy, and a possibility of not achieving a diagnosis even after the biopsy. Techniques and types of various nail biopsies are being discussed in this article. The specimen could be collected as an excision biopsy, punch biopsy, shave biopsy, or longitudinal biopsy. The trick lies in choosing the appropriate area for biopsy. Various biopsy types discussed in this article include nail plate biopsy (easiest and least scarring; nail bed biopsy (elliptical excision or punch; nail matrix biopsy (elliptical excision, punch excision (≤3 mm or tangential/shave excision; and nail fold biopsy. Complications reported along with means to minimize them are also discussed.

  20. Titanium exposure and yellow nail syndrome

    2015-01-01

    Full Text Available Yellow nail syndrome is a rare disease of unclear etiology. We describe a patient who develops yellow nail syndrome, with primary nail and sinus manifestations, shortly after amalgam dental implants. A study of the patient's nail shedding showed elevated nail titanium levels. The patient had her dental implants removed and had complete resolution of her sinus symptoms with no change in her nail findings. Since the patient's nail findings did not resolve we do not believe titanium exposure is a cause of her yellow nail syndrome but perhaps a possible relationship exists between titanium exposure and yellow nail syndrome that requires further studies.

    Lepore, Luciano; Lepore, Stefano; Maffulli, Nicola

    2003-01-01

    We report a comparative study between an inflatable expandable nail and a traditional locked intramedullary implant in closed fractures of the femoral shaft. We matched each of 43 patients who had undergone intramedullary fixation with an inflatable expandable nail with a patient of the same sex, age (within 2 years), and fracture who had undergone statically locked intramedullary fixation with traditional nails. The mean duration of surgery was significantly shorter in the patients who were treated with the inflatable expandable nail. There were no differences in average blood loss, transfusion requirements, or hospitalization. Five of the patients who underwent traditional nailing required dynamization to achieve union. The inflatable expandable nail allows effective management of diaphyseal fractures of the femur. Interlocking is not necessary, operative times are reduced, and exposure to ionizing radiation is minimized. At present, however, the inflatable expandable nail used in the this investigation is markedly more expensive than traditional devices.

  14. The nail in the elderly.

    Science.gov (United States)

    Baran, Robert

    2011-01-01

    Treating elderly patients has become common in daily clinical practice. Consequently, it is important to focus our interest on a neglected region: the nail area. Anatomy and physiology are indispensable for a good comprehension of some phenomenons. Histopathology of senile changes may explain some pathologic situations and is indispensable for diagnosing uncommon tumors. Chemical composition shows that a normal nail contains 18% water. The rate of linear nail decreases as age advances. Ridging is a normal finding on fingernails, with color varying from shades of yellow to grey. The most common disorders, however, are linked to repeated trauma, with sometimes ingrowing toenails with different appearances. Tumors in the nail area are relatively frequent. Nail fungal infection may be isolated or associated with conditions such as psoriasis and diabetes. The management of the main nail disorders observed in the elderly are presented.

    2017-06-01

    Intramedullary nailing, as the gold standard stabilisation method of most long bones, has been tailed by its extensive use as the basic tool of investigating the immune response to trauma in many large and small animal models, as well as at the clinical setting. Over the last few decades a complex map of interactions between pro and anti-inflammatory pathways has been the result of these significant global research efforts. Parallel to the evolution of modern nailing and reaming techniques, significant developments at the fields of other disciplines relevant to trauma care, has improved the contemporary management of injured patients, challenging previous concepts and altering clinical barriers. The current article aims to summarise the current understanding of the effect of instrumenting the medullary canal after trauma, and hint on potential future directions. Copyright © 2017.

    The lacquer figure with meridian-points marked of the western Han dynasty, unearthed in Tianhui town, Jinniu district, Chengdu in 2012, has been the earliest and the most complete human figure of meridian-acupoints in China so far. There were over ten courses of meridians, and over 100 visible acupoints as well as multiple intaglio inscriptions. All of them are valuable in academic study. The writers introduced the lacquer figure un- earthed in Laoguanshan in terms of the briefs and characteristics of meridian and acupoint distributions, which give the references to the future studies.

    This video demonstrates the technique of intramedullary nailing for a humeral shaft fracture. The patient is a 30-year-old man who sustained a gunshot wound to his right arm. The patient was indicated for humeral nailing given the comminuted nature of the diaphysis and to allow for minimal skin incisions. Other relative indications include soft-tissue compromise about the arm precluding a large surgical exposure. This video presents a case of a comminuted humeral shaft fracture treated with an intramedullary nail. Anatomic reduction and stable fixation was obtained with this technique. This case demonstrates a soft-tissue sparing technique of humeral shaft fixation using a humeral intramedullary nail. The technique is easy to perform and has significant benefits in minimizing surgical exposure, decreasing operative time, and decreasing blood loss. In the correct clinical setting, humeral nailing provides an expeditious form of fixation that restores length, alignment, and rotation of the fracture humeral diaphysis.

  20. The analysis of European lacquer: optimization of thermochemolysis temperature of natural resins

    2016-12-01

    In order to optimize chromatographic analysis of European lacquer, thermochemolysis temperature was evaluated for the analysis of natural resins. Five main ingredients of lacquer were studied: sandarac, mastic, colophony, Manila copal and Congo copal. For each, five temperature programs were tested: four fixed temperatures (350, 480, 550, 650 °C) and one ultrafast thermal desorption (UFD), in which the temperature rises from 350 to 660 °C in 1 min. In total, the integrated signals of 27 molecules, partially characterizing the five resins, were monitored to compare the different methods. A compromise between detection of compounds released at low temperatures and compounds formed at high temperatures was searched. 650 °C is too high for both groups, 350 °C is best for the first, and 550 °C for the second. Fixed temperatures of 480 °C or UFD proved to be a consensus in order to detect most marker molecules. UFD was slightly better for the molecules released at low temperatures, while 480 °C showed best compounds formed at high temperatures.

    1984-01-01

    The interactions of one-electron reduced metronidazole (ArNO2.-) and O2.- with native and Type-2-copper-depleted Vietnamese- and Japanese-lacquer-tree laccases were studied in aqueous solution at pH 6.0 and 7.4 by using the technique of pulse radiolysis. On reaction with ArNO2.-, in the absence of O2, the holo- and the Type-2-copper-depleted proteins accept, with reduction of Type 1 copper, 2 and 1 reducing equivalents respectively. On reaction with O2.- of both holo- and Type-2-copper-depleted Vietnamese-lacquer-tree laccase, almost complete reduction of Type 1 copper was observed and, after completion of the reaction, some (less than 20%) reoxidation of Type 1 copper occurs. Reduction of Type 1 copper of the laccases by these one-electron donors occurs via a bimolecular step; however, the rate of reduction of Vietnamese-lacquer-tree laccase is over 10 times that of Japanese-lacquer-tree laccase. It is inferred that electrons enter the protein via Type 1 copper with, in the case of the holoprotein, subsequent rapid intramolecular transfer of 1 reducing equivalent within the protein. Furthermore it is suggested that intra-molecular electron transfer to Type 3 copper atoms is slow and, in the case of Type-2-copper-depleted protein, may not occur. This slow process may partially account for the variation of the catalytic activities of 'blue' oxidases. PMID:6089764

    Full Text Available The yellow nail syndrome is a scarcely described condition characterized by dystrophic yellowish nails, respiratory disturbances and lymphedema; while the pincer nail deformity is characterized by thickening and excessive transverse curvature of the nail plate. The objective of this case study is to report a 76-year-old Japanese descent woman with yellow nail syndrome and pincer nails, intestinal polyps, and sigmoid colon adenocarcinoma. Both the yellow nail syndrome and pincer nails may develop in association with malignancies, either by chance or by some etiopathogenic mechanism not well-known.

    Full text: Lacquer-type deposits from 4 naturally aged red wines and one 'artificially', aged wine (by heating for 16 hrs at 84 deg C) were obtained from the Australian Wine Research Institute, Adelaide, and examined by EPR spectroscopy with a Varian E- 12 spectrometer working at ∼ 9.1 GHz The naturally aged wine deposits showed Fe 3+ in a low-symmetry site (g = 4.3), and Cu 2+ in an axial symmetry site (as deduced from the hyperfine structure) showing superhyperfine structure from N nuclei. A strong free radical signal was also present. The artificially aged wine deposit spectrum was similar, except no superhyperfine structure was present. The deposits are known to be anthocyanines cross-linked to a protein. The older the wine, the more intense was the superhyperfine structure, due to copper-amine interaction with the protein. The free radical signal is associated with the anthocyanines

    The topical treatment of nail fungal infections has been a focal point of nail research in the past few decades as it offers a much safer and focused alternative to conventional oral therapy. Although the current focus remains on exploring the ways of enhancing permeation through the formidable nail barrier, the understanding of the nail microstructure and composition is far from complete. This article reviews our current understanding of the nail microstructure, composition and diseases. A few of the parameters affecting the nail permeability and potential causes of the recurrence of fungal nail infection are also discussed. © 2017 Blackwell Verlag GmbH.

    Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (pNail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study.

    Due to the health risk related to occupational air pollution exposure, we assessed concentrations and identified sources of particles and volatile organic compounds (VOCs) in a handcraft workshop producing fishing lures. The work processes in the site included polyurethane molding, spray painting, lacquering, and gluing. We measured total VOC (TVOC) concentrations and particle size distributions at three locations representing the various phases of the manufacturing and assembly process. The mean working-hour TVOC concentrations in three locations studied were 41, 37, and 24 ppm according to photo-ionization detector measurements. The mean working-hour particle number concentration varied between locations from 3000 to 36,000 cm-3. Analysis of temporal and spatial variations of TVOC concentrations revealed that there were at least four substantial VOC sources: spray gluing, mold-release agent spraying, continuous evaporation from various lacquer and paint containers, and either spray painting or lacquering (probably both). The mold-release agent spray was indirectly also a major source of ultrafine particles. The workers' exposure can be reduced by improving the local exhaust ventilation at the known sources and by increasing the ventilation rate in the area with the continuous source.

    Nail changes are present in about 50% of psoriasis patients and tend to be refractory to conventional treatments. Pulsed dye laser has emerged as an alternative therapy. Our aim is to evaluate the efficacy of pulsed dye laser in nail psoriasis and the impact of treatment on quality of life. Fourteen patients were treated in monthly sessions for three months. The outcome assesment was made by the Nail Psoriasis Severity Index (NAPSI). The median improvement in the scores of the overall NAPSI, nail bed NAPSI, and nail matrix NAPSI were 44.2% (P = 0.002), 50% (P = 0.033) and 65.1% (P = 0.024), respectively. PMID:29364458

    Human hereditary nail disorders constitute a rare and heterogeneous group of ectodermal dysplasias. They occur as isolated and/or syndromic ectodermal conditions where other ectodermal appendages are also involved, and can occur associated with skeletal dysplasia. 'Nail disorder, nonsyndromic congenital' (OMIM; Online Mendelian Inheritance in Man) is subclassified into 10 different types. The underlying genes identified thus far are expressed in the nail bed and play important roles in nail development and morphogenesis. Here, we review the current literature on nail disorders and present a coherent review on the genetics of nail disorders. This review will pave the way to identifying putative genes and pathways involved in nail development and morphogenesis. © 2015 British Association of Dermatologists.

    Manufactured nanomaterials are projected to be used on a large scale in paints and lacquers. We selected seven commercially interesting materials: Three titanium dioxide-based (two coated rutile; one uncoated anatase), one carbon black (Flamrüss 101), one kaolinite clay, and two silica products, whereas carbon black, Printex 90, was used as reference material. DNA damaging activity and inflammogenicity (pulmonary cell composition and mRNAs) were determined 24 h after intratracheal instillation of a single dose of 54 μg in mice. Greatest inflammation was induced by Printex 90 and uncoated titanium dioxide. The inflammatory potency correlated with instilled surface area (R(2) = 0.94) but not with material volume (R(2) = 0.17). The coated titanium dioxides induced DNA damage in lung lining fluid cells. The uncoated titanium dioxide was not DNA damaging by the comet assay 24 h after exposure despite being highly inflammogenic. This suggests that inflammation is not a prerequisite to DNA damage in titanium dioxide-based products.

  10. Comparative EIS and XPS studies of the protective character of thin lacquer films containing CR or P salts formed on galvanised steel, galvanneal and galfan substrates

    Energy Technology Data Exchange (ETDEWEB)

    Feliu, S.; Barranco, V

    2004-03-01

    X-ray photoelectron spectroscopy (XPS) is used to analyse variations during exposure to humidity and UV radiation (UVCON test) in the chemical composition of the outer surface of organic coatings (lacquers) containing phosphating or chromating reagents applied on galvanised steel, galvanneal and galfan substrates. By means of electrochemical impedance spectroscopy (EIS) measurements the protective character of the coatings analysed by XPS is studied and an attempt is made to establish possible relationships between the chemical composition of the surface of the lacquered substrates after exposure to the UVCON test and their electrochemical characterisation in immersion in a 3% NaCl solution. In general, the formation of defects or the loss of adhesion of the lacquer film leads to a significant reduction in charge transfer resistance values and, at the same time, an increase in interfacial capacitance values. The special behaviour of the galfan/lacquer 'with chromating reagents' system is associated with the presence of a thin insulating film of chromium and aluminium oxides at the base of the pores in the lacquer. Interfacial capacitance values tend to evolve in close correspondence with the content of some elements on the surface of the materials.

  11. Parrot Beak Nails Revisited: Case Series and Comprehensive Review.

    Science.gov (United States)

    Chen, Stella X; Cohen, Philip R

    2018-03-01

    The term "parrot beak nail" describes a morphologic change of the nail plate characterized by excessive forward curvature. It may be associated with systemic disease or, most commonly, occurs as an idiopathic finding complicated by delayed nail plate trimming. The characteristics of parrot beak nails in ten men are described, and the features of this acquired nail deformity are reviewed. Of the ten patients, six presented with concurrent neuropathies that resulted in frequent foot injuries or falls. While the true incidence of parrot beak nails is unknown, this nail deformity occurred in 2.1 % of patients seen by a single physician during a 3-month period. In conclusion, parrot beak nails secondary to poor nail care may lead to functional impairment, tissue injury, and subsequent infections. Therefore, it is important for clinicians to look for these nail lesions on cutaneous examination and recommend frequent nail trimmings to individuals with parrot beak nails.

Barbed nails are designed to resist dislodgment once embedded, and any attempt at removal may splay open the barbs along the path of entry, with the potential for significant soft-tissue and neurovascular injury. A 25-year-old man sustained a nail impalement of the cervical spine from accidental discharge of a nail gun. The patient was noted to be fully conscious with no neurological deficits. Cervical Zone 2 impalement was noted, with only the head of the nail visible. Angiography revealed the nail lying just anterior to the right vertebral artery (VA), with compression of the vessel. Preoperatively, analysis of a similar nail revealed that orientation of the head determined position of the barbs. A deep neck dissection was then performed to the lateral aspect of the C-3 body, using the nail as a guide. Prior to removal, the nail was turned 180° to change the position of the barbs, to prevent injury to the VA. Nail removal was uneventful. The authors present a simple technique for treatment of a nail-gun injury with a barbed nail. Prior to removal, radiographic analysis of the impaled nail must be performed to determine the presence of barbs. If possible, the surgeon should request a similar nail for analysis prior to surgery. Last, the treating surgeon must have knowledge of the barbs' position at all times during nail removal, to prevent damage to critical structures.

  13. Properties of Polymer-Composite Used as Fills of Asian Lacquerware: Issues on Restoration Processes of Lacquered Objects from Cultural Heritage

    2015-01-01

    Full Text Available One of the common problems encountered in lacquerware issued from cultural heritage is the appearance of lifting areas and some losses of material. Composite systems made of commercial polymer and different fills were tested as filling agents for the cracking, splitting, and losses compensation of Asian lacquer. For that purpose, the stability of traditional and modern commercially available materials usually used in the restoration practice of historical lacquerware was assessed. Their thermomechanical and chemical properties and surface state were evaluated by a set of techniques (TGA, DMA, mechanical test, contact angle value, and microtopography. There is a drastic change of the behavior of the interface between fill and Asian lacquer, dependent on the nature of the composite fillers. So the evaluation of materials and processes for the restoration of Asian lacquer were emphasized. The commercial Paraloid B72 used with glass microspheres as additives appeared to be the most stable of all of the investigated fillers.

  14. Intramedullary nailing of tibial shaft fractures.

    Science.gov (United States)

    Kyrö, A; Lamppu, M; Böstman, O

    1995-01-01

    Sixty-four displaced tibial shaft fractures were treated using intramedullary nailing, either primarily or after an attempt at conservative treatment, which consisted of closed reduction under anaesthesia and immobilisation in a long-leg plaster cast. There were 37 closed and 27 open fractures. Three patients had a fracture of both tibiae. The median time period from the intramedullary nailing of the closed solitary fractures to union was about the same after primary nailing as after delayed nailing. Although the fractures were different in these groups, it is possible that the time spent in conservative treatment before intramedullary nailing brings no additional benefits. The incidence of deep infection in open fractures after primary nailing was 1/16. The fractures, in which an acceptable position could not be maintained using conservative methods, were mainly spiral in configuration and located in the distal third or at the junction of the middle and distal thirds of the tibia.

    Qadripur, S A; Schauder, S; Schwartz, P

    2001-07-01

    Black nails caused by Proteus mirabilis were seen in a motor mechanic and in a petrol pump attendant. Proteus mirabilis is a gram-negative bacillus that generates hydrogen sulfide. This compound reacts with traces of metals in the nail plate such as zinc, nickel, cobalt, iron, manganese, tin, copper and lead. Metal sulfides blacken the nail plate. The protracted course of the discoloration over months corresponds to the slow reactions of metals with hydrogen sulfide. The disappearance of the blackening after topical treatment with chinosol, tincture of iodine and chloramphenicol solution supports the etiologic connection between black nails and Proteus mirabilis. Wet and dirty work encourages the colonisation of Proteus mirabilis between nail fold and nail plate.

    2004-09-01

    Onychomatricoma is a rare fibroepithelial lesion of the nail matrix with peculiar clinical and histological features. Clinically, it is characterized by a longitudinal band of yellow thickening of the nail plate with transverse overcurvature and splinter hemorrhages. Nail avulsion exposes a villous tumor of the matrix with filamentous digitations extending into multiple holes of the nail plate. Histologically, a thick keratogenous zone forms a thickened nail plate. The lesion in its proximal portion is characterized by deep epithelial invaginations and by a stroma organized in two layers. The distal zone corresponds to multiple fibroepithelial projections extending into the nail plate. The diagnosis can be difficult in the presence of misleading clinical features or when the specimen is incomplete or examined with an improper orientation. Surgical resection is the recommended treatment.

    2004-03-01

    Artificial nails are an increasingly popular cosmetic enhancement to the natural nail. Several forms are available, including sculptured nails, photobonded nails, and preformed nails. Reactions to artificial nails have included paronychia, onychodystrophies, and dermatitis at contact areas and at sites distant to the contactant. We present a patient who developed erythema and painful pruritic vesicles of the paronychial tissue several hours after the application of sculptured nails. A strong reaction of erythema and edema occurred at the site of methyl methacrylate and ethylene glycol dimethacrylate testing. Removal of the artificial nails resulted in resolution of the reaction.

    Chronic anterior knee pain is the most common complication after tibial nail insertion. Its etiology remains unknown, and multifactorial sources have been suggested. The authors believe that nail prominence and the insertion point of the nail are important in the development of anterior knee pain. The purpose of this retrospective study was to evaluate the roles of the insertion point and nail prominence in anterior knee pain after tibial intramedullary nailing using a transtendinous approach and a common nail type. A total of 108 patients with tibial shaft fractures underwent reamed intramedullary nailing using a transtendinous approach between 2006 and 2009. Mean follow-up was 26.8±5.0 months. A visual analog scale (0-100) was used to estimate anterior knee pain severity while patients performed 7 activities retrospectively. Radiographic assessments, including nail prominence and insertion point, were performed. Sixty (55.6%) patients experienced knee pain (group P) and 48 (44.4%) did not (group N). Significant differences were not found between the groups with respect to demographics, nail diameters, or fracture classifications. Less superior and more anterior nail prominences in radiographic assessments were significantly associated with anterior knee pain. When the insertion point was over the bottom half of the anterior cortex, the influence of anterior nail prominence was more obvious. Nail removal resulted in diminished pain during the 7 assessed activities. Nail insertion should be over the bottom half of the anterior cortex, with minimal anterior nail prominence. If anterior knee pain occurs, removal of the nail should be considered. Copyright 2014, SLACK Incorporated.

  1. Nail tic disorders: Manifestations, pathogenesis and management.

    Singal, Archana; Daulatabad, Deepashree

    2017-01-01

    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. Some uncommon and rare nail tic disorders are onychoteiromania, onychotemnomania, onychodaknomania and bidet nails. Onychophagia is chronic nail biting behavior which usually starts during childhood. It is often regarded as a tension reducing measure. Onychotillomania is recurrent picking and manicuring of the fingernails and/or toenails. In severe cases, it may lead to onychoatrophy due to irreversible scarring of the nail matrix. Very often, they occur in psychologically normal children but may sometimes be associated with anxiety. In severe cases, onychotillomania may be an expression of obsessive-compulsive disorders. Management of nail tic disorders is challenging. Frequent applications of distasteful topical preparations on the nail and periungual skin can discourage patients from biting and chewing their fingernails. Habit-tic deformity can be helped by bandaging the digit daily with permeable adhesive tape. Fluoxetine in high doses can be helpful in interrupting these compulsive disorders in adults. For a complete diagnosis and accurate management, it is imperative to assess the patient's mental health and simultaneously treat the underlying psychiatric comorbidity, if any.

    2011-04-01

    To evaluate the clinical characteristics and treatment outcomes of patients undergoing surgical nail avulsion. Retrospective study. Two dermatology centres in Hong Kong. A total of 32 patients with nail diseases who underwent 33 nail avulsion procedures were reviewed from case records. Age, gender, co-morbidities, disease duration, clinical features, histopathology and fungal culture of nail plate, nail bed specimen for fungal culture in appropriate cases, and postoperative outcome. The mean age of the patients at the time of nail avulsion was 54 (range, 27-86) years. The most frequent preoperative findings were thickened nails (23 specimens, 70%) and discolouration (20 specimens, 61%). Onychomycosis was the most common pre-consultative diagnosis (20 specimens, 61%). Prior to nail avulsion, topical or systemic treatment had been tried in more than half of the cases. Histopathology of the avulsed nails confirmed onychomycosis in 24 (73%) of specimens. The clinical cure rate was 88% and the mycologic cure rate was 100%. The procedure was well tolerated without significant complications. Relapse was only noted in three (9%) of the patients having nail avulsions. The time for full re-growth ranged from 5 to 10 months. Total nail avulsion is an effective management option for patients whose diagnosis of onychomycosis was doubtful, and constitutes a treatment armamentarium especially for patients with single or oligo-onychomycosis.

  5. Microstructure of Horseshoe Nails Using Neutron Diffraction

    Goossens, D. J.; Studer, A. J.; Stachurski, Z. H.

    2010-04-01

    Neutron diffraction allows nondestructive testing of the bulk microstructure of mechanical components. The microstructures of horseshoe nails made through three different processes have been explored as a function of position along the nail. Despite all nails being made of similar plain low-carbon steel and being process annealed after manufacture, the microstructures are far from the same. Nails made from strip, using a cold forging stamping process, show narrower diffraction peaks indicating a narrower distribution of lattice parameters and also show diffraction peak intensity ratios closer to those expected for unstrained steel. Thus, the distribution of the orientation of grains in these nails is closer to that of undistorted steel compared to nails made through the other two processes considered—one a drawing from wire and the other a combination of rolling and cold forging. The blades of the drawn nails showed little preferred orientation but the converse was true in the heads. Differing patterns of preferred orientation suggest that the various manufacturing approaches result in substantially different mechanical advantages for the three types of nails, a result in accord with mechanical testing.

    2005-01-01

    Full Text Available Nail disorders are frequent among the geriatric population. This is due in part to the impaired circulation and in particular, susceptibility of the senile nail to fungal infections, faulty biomechanics, neoplasms, concurrent dermatological or systemic diseases, and related treatments. With aging, the rate of growth, color, contour, surface, thickness, chemical composition and histology of the nail unit change. Age associated disorders include brittle nails, trachyonychia, onychauxis, pachyonychia, onychogryphosis, onychophosis, onychoclavus, onychocryptosis, onycholysis, infections, infestations, splinter hemorrhages, subungual hematoma, subungual exostosis and malignancies. Awareness of the symptoms, signs and treatment options for these changes and disorders will enable us to assess and manage the conditions involving the nails of this large and growing segment of the population in a better way.

  14. Flexible Intramedullary Nailing for Paediatric Shaft of Femur Fractures – Does the Number of Nails Alter the Outcome?

    Directory of Open Access Journals (Sweden)

    B Kanthimathi

    2011-07-01

    Full Text Available BACKGROUND: The use of flexible intramedullary nailing, allowing micro movement at the fracture site, results in excellent outcomes regardless of the number of nails used. We undertook analysis of the outcomes of flexible nailing with reference to the number of nails used. METHODS: Twenty patients with diaphyseal femur fracture aged 5-15 years were treated with retrograde flexible intramedullary nailing. The number of nails varied from single to multiple. The results were analysed with regard to the number of nails used. RESULTS: The mean patient age was 7.9 years; patients were followed up for a mean duration of 13.2 months. Those with two and three nails had similar results. CONCLUSION: A minimum of two flexible nails is needed for optimal fixation in paediatric femur shaft fractures. Also, limiting the number of implants to two is cost effective, decreases operative time, reduces radiation exposure and offers equal results to that of three nails.

  15. [The ultrastructure of psoriatic nail changes].

    Pfister, T C

    1982-10-07

    The various and subsequent psoriatic nail changes can only be understood on the basis of parakeratotic changes. If parakeratosis is localized in the nail matrix specific changes in the nail will result depending on localization and spreading in the matrix. Punctate indentations (pits) may develop; if there is a ribbon-like, square-dimensioned localization we see streaks and ridges (psoriasis unguis striata). If parakeratotic cells invade the whole of the matrix the so-called psoriasis unguis crateriformis will develop. Well-known to the dermatologist is the irregular salmon-colored patch--a type of psoriasis involving the nail-bed. This salmon-colored patch may finally cause onycholysis semilunaris as the nail plate is not fixed to the nail-bed any longer. There may be onycholysis, too, if the cuticle is involved in the course of the psoriatic change. A long-standing psoriasis of the nails is characterized by para- or hyperkeratotic masses ("Krümelnagel").

    Lovell, Jane; Krishna, Damodaran; Gehr, Eugene

    2017-06-01

    The extraction of broken femoral nails can be a challenging procedure and surgeons should be familiar with many different techniques. This paper demonstrates a case study and new, simple and cost effective technique for the removal of broken cannulated femoral nails. Our technique uses two guide wires of variable diameter and had several key points of differentiation from previous methods. Firstly, stuffing the nail with guide wires of greater total diameter than the cannula; secondly, reversing the second guide wire and finally, bending the tips of the wires. These innovations allow the technique to be used for narrow cannulated nails, superior purchase along the length of the nail, easy wire insertion and limited soft tissue damage. Our technique for the removal of broken femoral nails is quick, effective, cheap and easy to replicate and can be used by any generalist orthopaedic surgeon with basic equipment.

  20. Portable x-ray fluorescence for the analysis of chromium in nail and nail clippings

    Fleming, David E.B.; Ware, Chris S.

    2017-01-01

    Assessment of chromium content in human nail or nail clippings could serve as an effective biomarker of chromium status. The feasibility of a new portable x-ray fluorescence (XRF) approach to chromium measurement was investigated through analysis of nail and nail clipping phantoms. Five measurements of 180 s (real time) duration were first performed on six whole nail phantoms having chromium concentrations of 0, 2, 5, 10, 15, and 20 µg/g. Using nail clippers, these phantoms were then converted to nail clippings, and assembled into different mass groups of 20, 40, 60, 80, and 100 mg for additional measurements. The amplitude of the chromium Kα characteristic x-ray energy peak was examined as a function of phantom concentration for all measurement conditions to create a series of calibration lines. The minimum detection limit (MDL) for chromium was also calculated for each case. The chromium MDL determined from the whole nail intact phantoms was 0.88±0.03 µg/g. For the clipping phantoms, the MDL ranged from 1.2 to 3.3 µg/g, depending on the mass group analyzed. For the 40 mg clipping group, the MDL was 1.2±0.1 µg/g, and higher mass collections did not improve upon this result. This MDL is comparable to chromium concentration levels seen in various studies involving human nail clippings. Further improvements to the portable XRF technique would be required to detect chromium levels expected from the lower end of a typical population. - Highlights: • Portable x-ray fluorescence (XRF) was explored as a technique to assess levels of chromium in human nails or nail clippings. • Results were found to depend on the mass of clipping sample provided. • Minimum detection limits for chromium were similar to concentration levels found in previous studies of human nail clippings.

    2011-01-01

    Full Text Available The clinical suspicion of onychomyosis based on appearance of the nails, requires culture for confirmation. This is because treatment requires prolonged use of systemic agents which may cause side effects. One of the common problems encountered is improper nail sampling technique which results in loss of essential information. The unfamiliar terminologies used in reporting culture results may intimidate physicians resulting in misinterpretation and hamper treatment decision. This article provides a simple guide on nail sampling technique and the interpretation of culture results.

    Cameron, C D; Meek, R N; Blachut, P A; O'Brien, P J; Pate, G C

    2014-08-01

    We conducted a prospective, randomized study on 84 consecutive patients with 88 acute, traumatic femoral shaft fractures using 32 Grosse-Kempf nails, 29 Russell-Taylor nails, and 27 Synthes nails. Although total operative times and proximal and distal locking times were similar for the three groups, the procedure was faster with the Grosse-Kempf nail. Three proximal fractures could not be locked with the Synthes nail. At first follow-up, we found no significant difference in terms of pain, limp, range of motion, or time to union; however, we removed fewer Synthes nails to resolve patient complaints of pain. Three delayed unions were attributed to fracture distraction. We conclude that all three nails are suitable for the treatment of almost all femoral shaft fractures. A careful analysis of intraoperative technique and instrumentation indicates that all three nails can be used safely and easily once experience is gained. Clinical outcome is similar regardless of the nail chosen.

    Full Text Available Background: Thigmotropism is a biologic feature coping with the directional growth of cells following topographical guidance cues. This mechanism is involved in the invasive phase of pathogen and opportunistic fungi. It was shown experimentally with fungal hyphae of both dermatophytes and nondermatophyte molds, as well as with the mycelial phase of the dimorphic yeast Candida albicans. Objective: To revisit histomycology in onychomycoses of a diversity of fungal origins. Method: Histopathological section of nails plates were oriented parallel to the nail direction of growth. Result: Thigmotropism in part explains the patterns of orientations and shapes of fungi invading nail plates. It is probably influenced by onychochronobiology (speed of growth of the affected nails, and it governs various clinical presentations of onychomycoses.

Nail disorders although common in children in some parts of our country. This study was carried out to document the clinical and demographic pattern of nail disorders in a dermatology outpatient clinic of a pediatric hospital in Ankara, Turkey. Material and Methods: All consecutive patients a total of 3000 children from age 0-16 were admitted to dermatology outpatient clinic of Ankara Pediatric Hematology and Oncology Education and Research Hospital during January 2011 to December 2011 were studied and retrospectively evaluated for age, gender, drug use, diseases, systemic or genetic disorders and demographic features. Diagnostic evaluation results were noted and patients were categorized for demographic features and diagnosis. Results: These 133 patients (M: F 58:75, %44 vs 56, respectively were under 16 years of age and have 17 different dermatological disorders related with nail symptoms. Fifty three of (39,8% these patient were under 2 years of age, 31 (23.3% were between 3-5 years, 30 (22.5% were between 6-11 years old, 19 of 133 (14%, 2 were between 11-16 years of age. Through all of ages and independent of gender the most etiologies of nail disorders were, onychomadesis, paronychia, onycholysis, onychomycosis and systemic nail presentation of systemic dermatosis. Conclusion: Nail disorders are different in children than in adults. In our study, the first 5 years of age was found in 53% of nail disorders. Nail disorders are uncommon but may be seen as a part of a systemic disease and may be associated with cosmetic and psychologic problem.

    Due to its limited availability there has been very little research on the mesenchyme of the nail unit. Recently, we discovered specialized mesenchymal cells beneath the nail matrix and proposed to call them onychofibroblasts. The purpose of this study was to further delineate more precisely by histology and immunohistochemistry the specialized nail mesenchyme. Thirty supernumerary digits were obtained during operations to correct polydactyly. Longitudinal and transverse sections were obtained from formalin-fixed paraffin-embedded blocks. In sections stained with haematoxylin and eosin, a mesenchymal area that showed much more cellularity and less eosinophilic, loose connective tissue was identified beneath the nail matrix and nail bed. Using Alcian blue staining, mucin was detected in this mesenchymal area below the nail matrix and nail bed. Immnunohistochemically, CD10 and versican were expressed strongly in the mesenchyme containing onychofibroblasts under the nail matrix and nail bed. These results demonstrate the presence and localization of a specialized nail mesenchyme containing onychofibroblasts in a well-defined area beneath the nail matrix and nail bed. Thus, we propose the term onychodermis for this specialized nail mesenchyme that is histologically and immunohistochemically distinct from the dermis of other parts of the nail unit. © 2012 Blackwell Publishing Ltd.

    Onychomycosis is a worldwide problem with no tendency for self-healing, and existing systemic treatments achieve disease-free nails in only 35 to 76% of cases. Recently, treatment of nail fungus with a near-infrared laser has been introduced. It is assumed that fungal eradication is mediated by local heat. To investigate if laser treatment has the potential to eradicate fungal hyphae and arthrospores, laser heat application and propagation needs to be studied in detail. This study aimed to measure nail temperatures using real-time videothermography during laser irradiation. Treatment was performed using 808- and 980-nm linear scanning diode lasers developed for hair removal, enabling contact-free homogeneous irradiation of a human nail plate in one pass. Average and peak temperatures increased pass by pass, while the laser beam moved along the nail plates. The achieved mean peak temperatures (808 nm: 74.1 to 112.4°C, 980 nm: 45.8 to 53.5°C), as well as the elevation of average temperatures (808 nm: 29.5 to 38.2°C, 980 nm: 27.1 to 32.6°C) were associated with pain that was equivalent to that of hair removal procedures and was not significantly different for various wavelengths. The linear scanning laser devices provide the benefits of contact-free homogeneous heating of the human nail while ensuring adequate temperature rises.

    Full Text Available Bianca Maria Piraccini, Michela Starace Division of Dermatology, Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Bologna, Italy Abstract: Psoriasis is a common skin disease, with nail involvement in approximately 80% of patients. Nail psoriasis is often associated with psoriatic arthropathy. Involvement of the nails does not always have relationship with the type, gravity, extension, or duration of skin psoriasis. Nail psoriasis can occur at any age and all parts of the nails and the surrounding structures can be affected. Two clinical patterns of nail manifestations have been seen due to psoriasis: nail matrix involvement or nail bed involvement. In the first case, irregular and deep pitting, red spots of the lunula, crumbling, and leukonychia are seen; in the second case, salmon patches, onycholysis with erythematous border, subungual hyperkeratosis, and splinter hemorrhages are observed. These clinical features are more visible in fingernails than in toenails, where nail abnormalities are not diagnostic and are usually clinically indistinguishable from other conditions, especially onychomycosis. Nail psoriasis causes, above all, psychosocial and aesthetic problems, but many patients often complain about functional damage. Diagnosis of nail psoriasis is clinical and histopathology is necessary only in selected cases. Nail psoriasis has an unpredictable course but, in most cases, the disease is chronic and complete remissions are uncommon. Sun exposure does not usually improve and may even worsen nail psoriasis. There are no curative treatments. Treatment of nail psoriasis includes different types of medications, from topical therapy to systemic therapy, according to the severity and extension of the disease. Moreover, we should not underestimate the use of biological agents and new therapy with lasers or iontophoresis. This review offers an investigation of the different treatment options for nail

    Full Text Available The aim of the study was to evaluate results of closed intramedullary nailing using Talwarkar square nails in adult forearm fractures. We prospectively evaluated 34 patients with both bone forearm fractures. The average time to union was 12.8 (SD +3.2 weeks with cast support for a mean of 8.2 weeks. Union was achieved in 31 out of 34 patients. Using the Grace and Eversmann rating system, 17 patients were excellent, 10 were good, and 4 had an acceptable result. Three patients had non-unions, 2 for the radius and one for the ulna. There were two cases of superficial infection, one subject had olecranon bursitis, and one case of radio-ulnar synostosis. Complication rates associated with the use of square nails were lower compared to plate osteosynthesis and locked intramedullary nails. To control rotation post- operatively, there is a need for application of an above-elbow cast after nailing.

  11. Matrix effect on leaching of Bisphenol A diglycidyl ether (BADGE) from epoxy resin based inner lacquer of aluminium tubes into semi-solid dosage forms.

    To study the impact of different semi-solid dosage form components on the leaching of Bisphenol A (BPA) and Bisphenol A diglycidyl ether (BADGE) from the epoxy resin-based inner lacquer of aluminium tubes, the tubes were filled with different matrix preparations and stored at an elevated temperature. Despite compliance with the European Standards EN 15348 and EN 15766 on porosity and polymerisation of internal coatings of aluminium tubes, the commercially available tubes used in the study contained an increased amount of polymerisation residues, such as unbound BPA, BADGE and BADGE derivatives in the lacquer, as determined by acetonitrile extraction. Storage of Macrogol ointments in these tubes resulted in an almost quantitative migration of the unbound polymerisation residues from the coating into the ointment. In addition, due to alterations observed in the RP-HPLC chromatograms of the matrix spiked with BADGE and BADGE derivatives it is supposed that the leachates can react with formulation components. The contamination of the medicinal product by BPA, BADGE and BADGE derivatives can be precluded by using aluminium tubes with an internal lacquer with a low degree of unbound polymerisation residues.

    Distal femur fractures continue to be a complex surgical problem for which the incidence is increasing. Presently, there is a need for different constructs to address these complex fractures. This study attempts to define the biomechanical properties of several implants. A novel, prototype locking retrograde intramedullary nail and the Russell-Taylor femoral retrograde nail were tested at non-destructive, physiological, axial mode load strength using a young, synthetic bone model for a medial segmental shaft defect in the supracondylar region of the distal femur (medial gap of 10mm, 65mm proximal to the distal joint and parallel to the knee axis). Each specimen was compressively loaded and unloaded to the peak load for 80,000cycles at a 0.5Hz frequency. These were compared to the results from the same lab of the retrograde Trigen intramedullary nail. Motion and peak displacement were measured across the fracture site as a reflection of construct stability. Previous testing demonstrated that Trigen intramedullary nail had significantly less motion across the gap and increased overall stiffness of the construct (Pnails. Locking technology used in a nail biomechanically appears to lead to more micro-motion across the fracture gap and to less stiffness in this construct. Further research needs to be invested into intramedullary, locking technology before introducing it into clinical practice. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2017-01-01

    Psoriasis is a chronic recurrent inflammatory skin disease with prevalence of 1-3%. Nail psoriasis affects 10-90% of patients with plaque psoriasis. The aim of the article is to review the literature for the correlation between nail psoriasis and psoriatic arthritis (PsA) to provide rheumatologists a short review on features of nail psoriasis, methods of their assessment and possible clinical repercussions. The PubMed database was searched using the key words 'nail psoriasis' and 'psoriatic arthritis'. Psoriasis involving the nail matrix shows up as changes such as pitting, Beau lines, leukonychia, red spots in the lunula, or nail plate crumbling. Nail bed psoriasis manifests as onycholysis, oil drops (or salmon patches), dyschromia, splinter hemorrhages, or subungual hyperkeratosis. Nail psoriasis and psoriatic lesions in the gluteal cleft and on the scalp usually accompany PsA, especially in adult men.

    Although psoriatic nail lesions are small, they cause considerable discomfort for patients and adversely affect quality of life. Few studies have evaluated the dermoscopic features of psoriatic nails. The aim of this study was to clarify the dermoscopic features of nail psoriasis and identify those that reflect psoriatic activity. During biologic treatment of psoriasis, six patients with psoriatic nails twice underwent dermoscopic examination, with an interval of 17-42 weeks. We used the modified Nail Psoriasis Severity Index score and Psoriasis Area and Severity Index score to identify and assess dermoscopic features. We identified 10 dermoscopic findings, of which disappearance of diffuse scaling of the nail plate, transverse step-like notches and splinter hemorrhages of the nail bed, and appearance of erythematous borders of the onycholytic area were associated with improvement in Psoriasis Area and Severity Index score. Dermoscopy can detect nail changes during psoriasis treatment and should be used to evaluate treatment success. © 2017 Japanese Dermatological Association.

Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia. The more extensive the involvement, the more severe is the nail destruction. Pustular psoriasis may be seen as yellow spots under the nail or, in case of acrodermatitis continua suppurativa, as an insidious progressive loss of the nail organ. Nail psoriasis has a severe impact on quality of life and may interfere with professional and other activities. Management includes patient counseling, avoidance of stress and strain to the nail apparatus, and different types of treatment. Topical therapy may be tried but is rarely sufficiently efficient. Perilesional injections with corticosteroids and methotrexate are often beneficial but may be painful and cannot be applied to many nails. All systemic treatments clearing widespread skin lesions usually also clear the nail lesions. Recently, biologicals were introduced into nail psoriasis treatment and found to be very effective. However, their use is restricted to severe cases due to high cost and potential systemic adverse effects. Keywords: nail psoriasis, etiology, pathology, quality of life, impact, treatment

    The expandable intramedullary nail is self-locking and has the advantage of reducing operating time and exposure to ionizing radiation. The nail is recommended for simple diaphyseal fractures involving the middle third of long bones, where the nail can bypass the fracture site by at least 5 cm. We encountered a unique complication with the expandable nail in a simple transverse shaft fracture at the junction of the middle and distal third of the left femur in an otherwise healthy 57-year-old man. The fracture was reduced and a 12-mm expandable nail was inserted. Following full expansion, intraoperative radiographs were obtained prior to closure. After six postoperative weeks, it was noted that the nail expanded the femoral canal, converting a simple fracture to a distally progressing comminuted fracture with a butterfly fragment. A review of the intraoperative radiographs showed slight widening of the medullary canal at the level of the fracture. As the alignment was satisfactory and callus was present, no further surgical intervention was considered. The patient was advised not to bear weight and was provided with a locked knee brace in extension to wear for six weeks. Radiographs at 12 weeks demonstrated good progress of healing with adequate callus and the patient was permitted to bear weight as tolerated and commence knee flexion. The fracture united satisfactorily at four months. This adverse experience emphasizes that caution should be exercised when expanding the nail, with close observation of the medullary canal diameter during the later stages of expansion.

    Reamed locked intramedullary nailing remains the standard treatment for displaced tibial shaft fractures. Supra-patellar tibial nailing in the semiextended position has been suggested as a safe and effective surgical technique that allows mitigating certain challenges of the standard subpatellar approach. Suprapatellar nailing seems to facilitate achieving and maintaining fracture reduction, particularly in proximal third tibia fractures. Preliminary investigations have suggested that this technique is associated with a low rate of complications, including a reduced incidence of postoperative anterior knee pain. Further clinical investigations are necessary to establish overall complication rates and long-term subjective outcomes. Copyright 2015, SLACK Incorporated.

    Intramedullary nailing is the treatment of choice for fractures of the tibial shaft, which might necessitate the nail removal due to complications in the long-term. Although considered as a low-risk procedure, intramedullary nail removal is also associated with certain complications. Here, we compared the most commonly used stainless steel and titanium nails with respect to the complications during removal and clinical outcome for intramedullary nailing of diaphyseal fractures of the tibia. Sixty-two patients (26 females, 36 males) were included in this retrospective study. Of the removed nails, 24 were of stainless steel and 38 of titanium. Preoperative and intraoperative parameters, such as implant discomfort, anterior knee pain, operating time and amount of bleeding, and postoperative outcomes were evaluated for each patient. Titanium nail group had more, but not statistically significant, intraoperative complications than stainless steel group during the removal of nails (p = .4498). Operating time and amount of intraoperative bleeding were significantly higher in titanium group than stainless steel group (p = .0306 and p titanium nails than those of stainless steel nails, whereas there was no difference in terms of postoperative SF-36 and KSS scores. In conclusion, although greater bone contact with titanium increases implant stability, nail removal is more difficult, resulting in more longer surgical operation and more intraoperative bleeding. Therefore, we do not recommend titanium nail removal in asymptomatic patients.

    To assess patient outcome after nailing of the tibial shaft with the unreamed AO/ASIF nail. A retrospective study of 54 nailed fractures of the tibial shaft treated between 1990 and 1994. Follow-up was done at the outpatient clinic and included measurements of the lower limbs and x-rays. The study was conducted at the Hôpital de l'Enfant-Jésus, Québec, a centre specializing in trauma care. Fifty-four acute displaced fractures of the tibial shaft occurring in 52 patients were studied. Nailing with the Synthes AO/ASIF unreamed locked nails. Time to bone fusion, rate of infection, incidence of deformity and failure rate of the implants, especially the lock screws. The majority of fractures were associated with a high-speed trauma (40/54 or 74% of cases) and 18 (33%) were open fractures. Osteitis developed in one (1.8%) open type IIIA fracture. Bone fusion was observed clinically and radiologically after 29 weeks on average; none of the fractures presented residual deformity on rotation of more than 5 degrees or a difference in length of more than 1 cm or a frontal or sagittal displacement of more than 10 degrees. A single case of pseudoarthrosis was noted. One or more lock screws became deformed or broke in 16 (34%) tibias; however, this did not lead to any reduction loss. Four compartment syndromes were diagnosed. Excellent results were obtained with respect to limb alignment and length. Loss of joint mobility was minimal. The number of lock screw failures indicates that a delayed weight bearing could prevent this complication, especially when an interfragment space remains after the nail placement.

    Nail scabies is an interesting clinical presentation of scabies. Although it is usually found concomitant with characteristic dermatologic manifestations, it may present as an isolated finding in the immunocompromised host. This condition is commonly mistaken with other diseases such as nail dystrophy, nail psoriasis and onychomycosis. We report two cases of unusual nail presentations that provide clues to diagnosis. Also, literature on unusual nail and dermatologic presentations was reviewed to recognize dermatologist consideration for appropriate treatment options. © The Author [2016].

    1981-10-01

    Thirty-eight consecutive segmental fractures of the tibia were treated by intramedullary nailing with the Küntscher-Herzog nail. Twenty-two fractures were closed and sixteen were open. Reaming of the medullary cavity was performed and adequate fixation was ensured by use of a plaster cast. Weight-bearing was allowed after thirty-days for closed fractures and sixty days for open fractures. All of the closed fractures healed without malunion or infection. Of the patients with open fractures, one had an infection; one, non-union; and one, malunion. In all cases but one, union was slower at the distal fracture.

    Full Text Available Objectives: Intramedullary nailing is the treatment of choice for fractures of the tibial shaft, which might necessitate the nail removal due to complications in the long-term. Although considered as a low-risk procedure, intramedullary nail removal is also associated with certain complications. Here, we compared the most commonly used stainless steel and titanium nails with respect to the complications during removal and clinical outcome for intramedullary nailing of diaphyseal fractures of the tibia. Patients and methods: Sixty-two patients (26 females, 36 males were included in this retrospective study. Of the removed nails, 24 were of stainless steel and 38 of titanium. Preoperative and intraoperative parameters, such as implant discomfort, anterior knee pain, operating time and amount of bleeding, and postoperative outcomes were evaluated for each patient. Results: Titanium nail group had more, but not statistically significant, intraoperative complications than stainless steel group during the removal of nails (p = .4498. Operating time and amount of intraoperative bleeding were significantly higher in titanium group than stainless steel group (p = .0306 and p < .001, respectively. Preoperative SF-36 physical component and KSS scores were significantly lower in patients who had removal of titanium nails than those of stainless steel nails, whereas there was no difference in terms of postoperative SF-36 and KSS scores. Conclusion: In conclusion, although greater bone contact with titanium increases implant stability, nail removal is more difficult, resulting in more longer surgical operation and more intraoperative bleeding. Therefore, we do not recommend titanium nail removal in asymptomatic patients. Keywords: Fractures of tibial shaft, Removal of intramedullary nailing, Stainless steel nail, Titanium nail

    Nail health and appearance are global concerns. We investigated the use of biotin vitamin E, alpha-tocopherol, vitamin C (ascorbic acid), vitamin A, retinoids, retinol, retinal, silicon, zinc, iron, copper, selenium, and vitamin B12 (Cyanocobalamin) in nail health and disease. The evidence that we adduce in this paper suggests that: 1) proper nail care seems to help maintain nail health; 2) no evidence supports the use of vitamin supplementation with vitamin E, vitamin C (ascorbic acid), vitamin A, retinoids, retinol, retinal, silicon, zinc, iron, copper, selenium, or vitamin B12 (Cyanocobalamin) for improving the nail health of well-nourished patients or improving the appearance of nails affected by pathologic disease; and 3) brittle nail syndrome appears to abate with supplementation with a 2.5-mg dose of biotin daily or a 10-mg dose of silicon daily, a useful form of which is choline-stabilized orthosilicic acid.

    Nails are underutilized as diagnostic tools, despite being involved in many dermatologic conditions. This paper explores new concepts in the treatment of median nail dystrophy (MND), onychomycosis, and the nail pathology of hand, foot, and mouth disease (HFMD). A Pubmed database literature search was conducted for MND treatment, onychomycosis treatment, and HFMD nail pathology. Only papers published after January 2008 were reviewed. The results showed that 0.1% tacrolimus ointment can be an effective treatment for MND. Early studies on laser therapy indicate that it is a safe and efficacious treatment option for onychomycosis, compared to conventional oral antifungal agents. Vicks VapoRub (The Proctor & Gamble Company, Cincinnati, OH) is effective against onychomycosis and is a reasonable option in patients who choose to forgo conventional treatments. Lastly, there is evidence to support a correlation between HFMD and onychomadesis.

    By means on the basis of a prospective study of 33 osteosynthesis with the unreamed tibia nail (UTN) the following conclusions were found: 1. A technical simple, intramedullary solid strength bearing device in only two diameters is available, therefore costs for stock keeping are low. Systematic interlocking of the nail is necessary. Regarding the multiplicity of indication as well as the mechanical character the UTN is close to the principle of the internal fixator. 2. As a result of its solid constitution remarkable hollow cavities do not exist, so that retention of hematoma or secretions is limited (prophylaxis of infection). 3. In case of a closed nailing procedure the less rigid fracture fixation is favourable for the biology of the bone healing (fracture hematoma, less traumatic procedure without reaming of the medullary cavity, etc.). 4. The frequently observed breakage of interlocking bolts leads spontaneously to a dynamisation favourable as to time and therefore to a better bone healing process (callus formation). 5. Time intervals of bony fractures consolidation are significantly shorter compared to the exclusive osteosynthesis with the external fixator [3]. 6. The unreamed tibia nail is an implant for both primary stabilisation of closed diaphyseal fractures of the tibia with soft tissue injury and for secondary procedure/treatment for example after external fixator osteosynthesis or initial non-operative treatment. Early change of procedure seems to be of importance.

    Pemphigus vulgaris (PV) patients receiving immunosuppressive therapy may develop nail alterations resulting from infection, skin disorder, or drug regimen. This study aims to describe nail changes in PV female patients receiving immunosuppressive therapy and to report the frequency of associated fungal and bacterial growth in the patients' nails. Twenty-five female PV patients who had at least one acquired finger or toenail abnormality and had been administered at least one immunosuppressive drug were included in the study. Nail alterations were recorded. Nail scrapings were collected from abnormal nails for fungal and bacterial examination. Positive fungal and bacterial cultures were detected in 20 (80%) of patients' nail samples. Five patients reported nail alterations coinciding with disease onset, whereas 13 reported nail changes after administration of immunosuppressive therapy. Lack of a control group (patients on similar immunosuppressive medications for conditions other than PV) which would have further supported the findings demonstrated in this observational study. Nail abnormalities in severe PV patients are frequently associated with fungal and bacterial growth. Immunosuppressive therapy potentially initiates such changes.

    2008-05-01

    The Authors analyse the results of intramedullary nailing in a group of 101 femoral shaft fractures. Used nails: Universal Synthes (62 cases), Russel-Taylor (14), Gamma long (10), uncannulated femoral nail (9), cannulated femoral nail (4) and proximal femoral nail (2). Stabilisation of the femoral shaft fracture was possible using a reamed technique in 91 cases, unreamed in 10. All nails were locked. Dynamisation was performed in 35 cases and was not in 66. The fracture heal was faster with the reaming and dynamisation technique. Ten fractures were open (5 Gustilo I, 5 Gustilo II) and stabilisation with Universal Synthes nail (8 cases), Russel-Taylor nail (1) and Gamma long nail (1) was performed. No infection was detected. Lung embolism (6) and deep vein thrombosis (3) occurred only in the case of reamed nails. All results confirm the locking nail system as the best treatment in the shaft fractures, especially with new-generation nails.

    Effective transungual delivery of topical antifungal agents in onychomycosis has been hampered by poor nail permeation. To be effective they must have antifungal efficacy, and effectively permeate through the dense keratinized nail plate to the site of infection in the nail bed and nail matrix. The therapeutic efficacy of efinaconazole topical solution, 10% has been established in two phase 3 clinical trials in distal lateral subungual onychomycosis. To investigate the transungual delivery of efinaconazole in onychomycosis patients and its fungicidal activity in the toenail. Concentrations of efinaconazole were determined as part of a multi-center, open label study in forty onychomycosis patients following repeated application of efinaconazole topical solution, 5% and 10% to the toenails over 28 days, with a 2-week follow-up. Fungicidal activity against T. rubrum in the ventral layer of human nails was determined using an in vitro human nail infection model (ChubTur®). Efinaconazole concentrations in the nail were four orders of magnitude higher than MIC values of efinaconazole against dermatophytes. Further, nail drug concentrations were not influenced by the presence of disease or nail thickness, and maintained at high antifungal levels post-treatment. Efinaconazole was effective in reducing fungal viability, suggesting that sufficient amounts of efinaconazole were being delivered into the ventral layer of the nail plate. Effective transungual delivery of efinaconazole was demonstrated. The high efinaconazole concentrations in patient toenails and fungicidal activity in vitro potentially contribute to the clinical efficacy reported in phase 3 studies.

    A problem has arisen when replacing the reamed tibia nail by the massive unreamed tibia nail. In case of nail fracture it is difficult to remove the distal fragment from the medullary cavity. It may also occur that the connecting screw between the insertion handle and the nail breaks off at the edge of the implant, which much complicates removal of the nail. The authors have developed a technique to remove the implant without having to saw a fissure in the marrow. A concave instrument is slid over the part of the nail left behind after which the two are connected by means of a K wire. This method has been successfully applied in 2 patients.

    Sarcoidosis is a granulomatous disease which can affect multiple organ systems. Clinical and radiologic manifestations depend on the organ system involved and the chronicity of disease. Nail involvement in sarcoidosis is rare, but is clinically relevant as it indicates chronic systemic disease. Nail abnormalities can be identified radiographically, and when seen in patients with known or suspected sarcoidosis, should prompt careful evaluation of the underlying bone for osseous involvement. We describe a case of sarcoidosis with radiographic findings in the nails and distal phalangeal tufts, which were indicative of nail and osseous sarcoid involvement and strongly supported the presence of chronic systemic disease. Although the nail findings resolved clinically and on radiographs after treatment, the osseous findings showed only minimal improvement. To our knowledge, the radiographic findings of nail sarcoidosis have not been previously addressed in the literature. (orig.)

    Closed humeral nailing is now considered an alternative treatment for humeral-shaft fracture. The nail can be inserted with either the antegrade or retrograde method. We investigated and compared the problem of geometric mismatch of the humeral nail to the humerus between the two methods of insertion. The study was performed using virtual simulation based on computed tomography (CT) data of 76 Thai cadaveric humeri and the commonly used Russell-Taylor humeral nail 8 mm in diameter and 220 mm long. Mismatch of the nail to the intact humerus was analyzed and compared between the antegrade and retrograde nailing approaches. The results showed: the diameter of the medullary canal averaged 7.9-13.8 mm; the minimal reaming diameter to accommodate virtual nail insertion averaged 8.8-14.8 mm for the antegrade and 8.8-29.3 mm for the retrograde approach; the minimal reaming thickness of the inner cortex averaged 0.1-1.5 mm for the antegrade and 0.1-9.9 mm for the retrograde approach; the percentages of cortical bone removed prior to nail insertion were 3.8-107.1% and 3.8-1,287.6% for the antegrade and retrograde approaches, respectively; the eccentricity of the nail-medullary canal center were 0.4-3.4 and 0.4-10.6 mm for the antegrade and retrograde approaches, respectively. Less mismatching occurred with antegrade nailing than with the retrograde approach. Retrograde nailing requires excessive reaming at the distal part of the humerus to accommodate nail insertion. This may create bone weakness and the risk of supracondylar fracture. (author)

    87-year-old female underwent open reduction of distal femoral fracture and internal fixation with locking compression plate and bone graft. She was operated for ipsilateral proximal femoral fractures and stabilized by intramedullary interlocked nail 5 years ago. She developed stress fracture proximal to locked plate. We inserted Huckstep nail after removal of the previous operated proximal femoral nail without removing the remaining plate and screws. At 15 month followup the fractures have united. The Huckstep nail has multiple holes available for screw fixation at any level in such difficult situations.

    Nail-bed injuries are the most common hand injury in children. Surgical dogma is to replace the nail plate after repairing the nail bed. Recent evidence suggests this might increase infection rates and returns to clinic. The aim of this feasibility trial was to inform the design and conduct of a definitive trial comparing replacing or discarding the nail plate after nail-bed repair. This study recruited participants from four hand units in the UK between April and July 2015. Participants were children under the age of 16 years with a nail-bed injury requiring surgery. They were randomized to either having the nail plate replaced or discarded after nail-bed repair. The follow-up method was also allocated randomly (postal versus clinic). Information was collected on complications at 2 weeks and 30 days, and on nail-plate appearance at 4 months using the Zook classification. Two possible approaches to follow-up were also piloted and compared. During the recruitment phase, there were 156 potentially eligible children. Sixty were randomized in just over 3 months using remote web-based allocation. By 2 weeks, there were two infections, both in children with replaced nail plates. The nail-replaced group also experienced more complications. There was no evidence of a difference in return rates between postal and clinic follow-up. Recruitment was rapid and nail-bed repair appeared to have low complication and infection rates in this pilot trial. The findings have led to revision of the definitive trial protocol, including the mode and timing of follow-up, and modification of the Zook classification. © 2017 The Authors.

    2017-06-01

    Ingrown nails are a common problem, seen mostly in young adults. Also known as onychcrypotisis, this condition typically affects the great toenail. Four stages have been defined according to the severity and duration of the condition, and treatment varies from conservative to surgical techniques depending on the stage. We present our experience with this condition, describing the characteristics of our population and surgical treatment, in particular the super U technique. This was a retrospective, descriptive study of patients with ingrown great toenail treated surgically using the super U technique. We also describe postoperative management. Ten patients with a mean age of 35.7 years underwent operation, 9 for unilateral ingrown great toenail and 1 for bilateral disease. Stage II ingrown nail was the most common. Half of the patients had been treated previously using other surgical techniques. The mean time to healing was 6 weeks. The only postoperative complication was infection in 1 patient. Mild to moderate postoperative pain persisted for a week. The majority of patients were satisfied with the cosmetic result. We believe the super U technique is very useful in stage II ingrown nail and in disease that has recurred after previous surgery, and is the treatment of choice in stage III or IV disease in which excessive hypertrophic tissue is found.

    A 38-year-old man presented with whitish nail changes on all fingers as the sole symptom. The condition had developed within a few days and led to dystrophy of the proximal part of the nail plates. As microscopic examination of nail scrapings demonstrated budding hyphae and the patient working as a teacher reported frequent use of a wet sponge, antifungal therapy was initiated. Subsequent cultures and molecular typing identified Rhodotorula mucilaginosa (formerly R. rubra). This environmental yeast was repeatedly isolated despite of therapy with itraconazole. As no improvement was achieved and testing of the biological activity of the fungus revealed only marginal keratolytic activity, it was considered as a coloniser of a destructed nail matrix. Finally, a biopsy of the nail bed confirmed the diagnosis of nail psoriasis, which rapidly responded to treatment with acitretin and topical calcipotriol/betamethasone cream. Fungal growth in destructed nails masqueraded the underlying disease and may have triggered the psoriatic nail reaction. © 2013 Blackwell Verlag GmbH.

  4. Do fungi play a role in psoriatic nails?

    2007-11-01

    Onychomycosis is the most common disease of the nails and constitutes about a half of all nail abnormalities. Some factors like increasing age, male sex, repeated nail damage, genetic predispositions and underlying conditions, such as diabetes, immunodeficiency or peripheral arterial disease may predispose to develop onychomycosis. It is also suggested that abnormalities in nail morphology are the predisposing factors to onychomycosis. Psoriasis is one of the most common reasons of disturbed nail morphology and the spectrum of nail changes in psoriasis is very wide. Thus, there were suggestions that dystrophic nails in psoriatic patients lose their natural preventing barrier and therefore are more predisposed to fungal infection. This paper summarizes the knowledge about prevalence of onychomycosis among psoriatic patients and contains a literature review concerning this problem. Most authors report that the prevalence of onychomycosis in psoriatic patients is not higher than that in control population. However, especially yeasts and maybe moulds, probably as concomitant pathogens, are more often isolated from psoriatic patients than from non-psoriatic population. In reasonable cases, the mycological examination is required, especially when the clinical picture of the nails suggests the presence of fungal infection. In these cases, antifungal treatment may be beneficial for psoriatic patients.

    2011-01-01

    While intramedullary nailing has been established as the treatment of choice for diaphyseal fractures of the femur and tibia, its role in the management of diaphyseal humeral fractures remains controversial. The reasons include not only the complicated anatomy and unique biomechanical characteristics of the arm but also the fact that surgical technique and nail designs devised for the treatment of femoral and tibial fractures are being transposed to the humerus. As a result there is no consensus on many aspects of the humeral nailing procedure, e.g., the basic nail design, nail selection criteria, timing of the procedure, and the fundamental principles of the surgical technique (e.g., antegrade/retrograde, reamed/unreamed, and static/dynamic). These issues will be analyzed and discussed in the present article. Proposals aiming to improve outcomes include the categorization of humeral nails in two distinct groups: “fixed” and “bio”, avoidance of reaming for the antegrade technique and utilization of “semi-reaming” for the retrograde technique, guidelines for reducing complications, setting the best “timing” for nailing and criteria for selecting the most appropriate surgical technique (antegrade or retrograde). Finally, suggestions are made on proper planning and conducting clinical and biomechanical studies regarding the use of intramedullary nailing in the management of humeral shaft fractures.

    Full Text Available While antegrade nailing for proximal and diaphyseal femur fractures is a commonly utilized fixation method with benefits including early mobilization and high rates of fracture union, both intraoperative and postoperative complications may occur. Intraoperative errors include leg length discrepancy, anterior cortical perforation, malreduction of the fracture, and neurovascular injury, and postoperative complications include nonunion, malunion, infection, and hardware failure. This case series reviews complications affecting the distal femur after intramedullary nailing including fracture surrounding a distal femoral interlocking screw (Case #1, nonunion after dynamization with nail penetration into the knee joint (Case #2, and anterior cortical perforation (Case #3. Prevention of intraoperative and postoperative complications surrounding intramedullary nailing requires careful study of the femoral anatomy and nail design specifications (radius of curvature, consideration of the necessity of distal interlocking screws, the need for close radiographic follow-up after nail placement with X-rays of the entire length of the nail, and awareness of possible nail penetration into the knee joint after dynamization.

    Onychocryptosis is one of the most common painful nail conditions. Conservative treatment may take a long time to obtain effective results. The purpose of this study is to show the effectiveness of a conservative treatment of ingrown nails that shows rapid results. Patients with painful Stage 1 to 2 onychocryptosis who were not candidates or refused surgery were treated with the cotton cast. The severity and cause of onychocryptosis was clinically evaluated during a 2-month period. A questionnaire was applied to all patients to evaluate pain, final treatment, and possible complications. All patients noticed results in less than 72 hours. Pain subsided in less than 24 hours in half of the patients and before 72 hours in 100% of the patients without the need of other treatments. The use of the cast prevented surgery and the accompanying morbidities in most of the patients (80%). The "cotton nail cast" is an effective conservative method for mild nail embedding. It is easy to apply, inexpensive, relieves pain rapidly, and avoids surgery in most patients.

    To analyse the prevalence of fungi in abnormal nails by morphological diagnosis. Prevalence studies of onychomycoses in temperate climate zones have yielded widely varying rates, possibly reflecting the confounding effects of referral bias, sampling specificity and intrinsic sensitivity of the diagnostic techniques employed. The method employed to identify fungi in nails entailed primary fixation using a non-formaldehyde-based coagulative fixative (BoonFix; Finetec, Japan) and microwave-enhanced processing to histology, followed by staining the paraffin sections with periodic acid-Schiff, using haematoxylin as a routine counterstain. The results of 990 nail samples were tabled for statistical analysis related to gender, patient age and diabetes mellitus status. In four of the 990 (fungal infection in morphologically abnormal nails was found to be higher for persons or = 71 years. The 61% positivity rate for fungi found justifies systematic direct submission of samples from abnormal nails for histological confirmation in order to avoid unwarranted treatment.

  18. Safe surgical technique: intramedullary nail fixation of tibial shaft fractures.

    Zelle, Boris A; Boni, Guilherme

    2015-01-01

    Statically locked, reamed intramedullary nailing remains the standard treatment for displaced tibial shaft fractures. Establishing an appropriate starting point is a crucial part of the surgical procedure. Recently, suprapatellar nailing in the semi-extended position has been suggested as a safe and effective surgical technique. Numerous reduction techiques are available to achieve an anatomic fracture alignment and the treating surgeon should be familiar with these maneuvers. Open reduction techniques should be considered if anatomic fracture alignment cannot be achieved by closed means. Favorable union rates above 90 % can be achieved by both reamed and unreamed intramedullary nailing. Despite favorable union rates, patients continue to have functional long-term impairments. In particular, anterior knee pain remains a common complaint following intramedullary tibial nailing. Malrotation remains a commonly reported complication after tibial nailing. The effect of postoperative tibial malalignment on the clinical and radiographic outcome requires further investigation.

    This study demonstrates the potential of polymeric nanoparticles as drug reservoirs for sustained topical drug delivery into microneedle-treated human nail. Laser scanning confocal microscopy was used to image the delivery of a fluorescent model compound from nanoparticles into the nail. A label-free imaging technique, stimulated Raman scattering microscopy, was applied, in conjunction with two-photon fluorescence imaging, to probe the disposition of nanoparticles and an associated lipophilic 'active' in a microneedle-porated nail. The results provide clear evidence that the nanoparticles function as immobile reservoirs, sequestered on the nail surface and in the microneedle-generated pores, from which the active payload can be released and diffuse laterally into the nail over an extended period of time.

    Nails are integral extensions of the skin and they together form the largest organ of the human body. Changes in nail appearance can be due to external insults or internal pathologies, and nail signs have to be interpreted in light of a good history. We present an interesting case of a man who developed dark-green discolouration of his nails over a short period of time. His work as a chemical mixer rendered him susceptible to hazardous chemical exposure. A notification was filed and the local Occupational Health Department discovered insufficient protective gear and lack of protocols regarding hazards of isocyanate-based resin. The patient also reported washing utensils with bare hands. Based on the meniscal demarcation borders between the discoloured and normal areas, plus a positive bacterial culture from nail clippings, the final diagnosis of isocyanate-resin-induced onycholysis with secondary Pseudomonas infection remained as the most likely clinical diagnosis. 2015 BMJ Publishing Group Ltd.

    Penetrating craniocerebral injuries from nail gun use are rare. We describe a case of 10 self-inflicted nail gun injuries with intracranial penetrations. We also review the literature and discuss management strategies of such craniocerebral trauma. A 33-year-old male with a long-standing history of severe depression took a nail gun and sustained 10 penetrating intracranial injuries. Initial neuroimaging revealed 10 penetrating nails, all sparing the major cerebral vasculature. Immediate surgical removal was undertaken in the surgical suite using a combination of craniotomies, craniectomies, and blind removal. Intracranial injuries from self-inflicted nail gun misuse is becoming increasingly more frequent. Initial appropriate clinical decision-making are critical in preventing further cortical or vascular damage. PMID:26166596

    Primary fingernail changes that result from chemical exposures are seldom encountered in clinical practice. A cluster investigation was conducted on employees at a pesticide packaging company. Six employees reported simultaneous onset of defects occurring in their fingernails, including nail discoloration, nail dimpling, and nail shedding. Multiple pesticides and herbicides including diquat were used in the facility at the time of the cluster onset. A literature review noted 6 articles published before 1975 documenting similar nail changes associated with paraquat, diquat, or other herbicide use. Only one such case report published after 1985 could be located. Diquat was the only material that was previously reported in the medical literature as causing nail defects and also in use at this facility. Diquat exposure is the most plausible explanation for the observed changes in these workers' fingernails.

    Ninety-nine femoral shaft fractures were treated with locked intramedullary nails made from titanium alloy. One of the distal interlocking screws failed in six fractures (6%) and both screws failed in two fractures (2%). Delayed union was associated with all of the eight fractures that had locking screw failure. Young, heavier patients who had nails of small diameter had an increased risk of screw failure. Additional surgery was needed when both screws failed. The authors still use this nail, but currently prefer to ream the medullary canal more so that larger nails can be inserted. Decisions concerning weightbearing are made on an individual basis for each patient, and currently full weightbearing is delayed for young, active, and heavy patients. Two distal interlocking screws should be inserted for treatment of femoral shaft fracture when a Ti locked intramedullary nail is used.

    Thirty-five displaced tibial shaft fractures, treated with functional bracing were compared with 43 similar fractures, treated with locked intramedullary nailing. There were 22 excellent/good results in the brace group and 38 in the nail group. There was one infection in the brace group and three in the nailed group. There were five delayed unions and two nonunions in the brace group and one delayed union in the nail group. The functional results in the nailed group were better than the braced group but locked intramedullary nailing of tibial shaft fractures require special resources and training. Locked intramedullary nailing fullfils all the functional criteria for acceptable fracture care.

    An investigation of contemporary exposure to formaldehyde and organic solvents has been carried out during surface coating with acid-curing lacquers and paints in the Norwegian woodworking and furniture industry over a period of 3 years. The investigation covered 27 factories of different sizes and with different types of production, and totally 557 parallel formaldehyde and solvent samples were collected. The formaldehyde concentration (geometric mean) was 0.15 ppm (range 0.01-1.48 ppm) with about 10% of the samples exceeding the Norwegian occupational exposure limit of 0.5 ppm. The solvent concentration as additive effect (geometric mean) was 0.13 (range 0.0004-5.08) and about 5% of the samples exceeded the Norwegian occupational exposure limit. The most frequently occurring solvents from acid-curing lacquers were n-butyl acetate, ethanol, ethyl acetate and 1-butanol, which were found in 88-98% of the samples. Toluene, n-butyl acetate and 1-butanol were the only solvents with maximum concentrations exceeding their respective occupational exposure limits. Curtain painting machine operators were exposed to the highest concentrations of both formaldehyde (geometric mean 0.51 ppm, range 0.08-1.48 ppm) and organic solvents (additive effect, geometric mean 1.18, range 0.02-5.08). Other painting application work tasks such as automatic and manual spray-painting, manual painting and dip painting, showed on average considerably lower concentrations of both formaldehyde (geometric means 0.07-0.16 ppm) and organic solvents (additive effect, geometric mean 0.02-0.18). Non-painting work tasks also displayed moderate concentrations of formaldehyde (geometric means 0.11-0.17 ppm) and organic solvents (additive effect, geometric mean 0.04-0.07).

    Full Text Available Nail biting (NB is a common, but unresolved, problem in psychiatry, psychology, medicine and dentistry. While it seems that NB is a simple behavior that can be stopped easily, many of the children with NB have already tried to stop it, but they have not been successful. The frustrations due to failed attempt involve others such as parents and siblings. The present review aims at providing an overview of prevalence, co-morbidities, education and counseling, and management for NB. Overall, the reviewed literatures suggest that co-morbidities of psychiatric disorders and other stereotypic behaviors in clinical sample of children with NB is more than 80%, and more than half of the parents suffer from psychiatric disorders mainly depression. Treatment of NB, however, is not as easy as it seems. The management of NB is much more complicated than just focusing on stopping it. Nail biting cannot be managed without considering its co-morbidities, antecedents and consequences. It might be concluded form the reviewed literature that children with NB, parents, siblings, and teachers should be educated about what to do and what not to do about NB. Punishment is not effective. Moreover, clinical randomized controlled trials are required to make available evidence-based behavioral and pharmacologic treatment protocols

    Intramedullary stabilization of periprosthetic distal femoral fractures by interlocking nailing. Closed reduction by retrograde nail can be combined with the use of transmedullary support screws (TMS principle of Stedtfeld). Supracondylar fractures above stable knee arthroplasty (Rorabeck types I and II), femoral shaft fractures ipsilateral of stable hip and/or knee arthroplasty, contraindications for antegrade nailing Closed box design of femoral implant, intercondylar distance of the femoral component smaller than nail diameter, more than 40° flexion deficit of the knee, inability to place two bicortical distal interlocking screws. Relative contraindication: insufficient overlap with proximal implants Supine position and knee flexion of approximately 45°. Fluoroscopy should be possible between the knee and hip. Longitudinal skin incision into the pre-existing scar over the patellar tendon which is then split. The nail entry point is located in the intercondylar groove at the deepest point of Blumensaat's line, often predetermined by the femoral arthroplasty component. Reaming is rarely necessary. Transmedullary support screws may correct axial malalignment during nail insertion. Static interlocking in a direction from lateral to medial by the aiming device. Insertion of locking cap. Retrograde nailing normally allows full weight bearing. Range of motion does not need to be restricted. Out of 101 fractures treated between 2000 and 2013 with a Targon RF nail (Aesculap, Tuttlingen, Germany) 10 were periprosthetic, all were classified as Rorabeck type II and of these 6 fractures were metaphyseal and 4 were diaphyseal. In four cases proximal implants were present. The mean operative time for periprosthetic fracture fixation did not significantly differ from that for normal retrograde femoral nailing. There were no postoperative infections, fixation failures or delayed unions. There was one revision for secondary correction of maltorsion.

    The purpose of this study was to analyse the results of tibial intramedullary nailing using an unreamed "Universal Elastic Bundle Nail". Forty-three intramedullary nailing of tibial shaft were done in 43 patients with recents fractures, from May 1993 and May 1996. There were 36 males and 7 females. The average age was 31.5 years (range 17-68 years). Thirty-three were injured in a traffic accident (20 motorcycles, 5 pedestrians and 8 car passengers), seven were injured in a home accident (fall) and three had a sport injury. There were 13 open fractures according to Gustilo: 5 grade I, 7 grade II and one grade III B. Eight fractures involved the proximal metaphyseal part of the tibia, 16 the distal metaphyseal part and 14 the tibial shaft; in five cases there were segmental fractures. According to AO classification there were: 10 fractures type A, 24 fractures type B and 9 fractures type C (5 segmental fractures). In 5 cases there were associated femoral fractures: three ipsilaterals and two controlaterals. All were treated in the same time: four by UEBN device and one by AO's nail. All the patients with type B and C fractures were positioned on a Maquet table with a boot traction or transcalcaneal pin traction (in the distal fractures). The nail was introduced after closed reduction through a vertical transpatellar tendon incision, without reaming procedure. Forty one fractures healed after an average time of 96 days (60-120). In 11 open fractures bone union occurred after 98 days (85-120). The distal fractures healed after a mean time of 86 days (60-120), proximal fractures in 123 days and mid shaft fractures in 98 days. In type A fractures bone union occurred after an average time of 68 days, while bone union occurred after a mean time of 100 days in type B and C fractures. Two patients with an open proximal type B fracture, had a delayed union: both healed after proximal screws removal. Two fractures healed with a valgus angulaton 5 degrees and 10 degrees. No

    Non-operative treatment with immobilization or isometric traction has been abandoned as treatment for fractures of the distal femur at the end of the 1960ies. The technique of open reduction and internal fixation with a condylar plate as suggested by the AO has been the golden standard since the 1970ies. However, anatomic reconstruction of the condylar region with interfragmentary screw fixation and axial realignment of the femur shaft with a plate are challenging procedures especially in the presence of severely compromised soft tissues and put periosteal blood supply at risk. Soft tissue complications, axial malalignment and delayed fracture healing times led to the consideration of alternative techniques, such as intramedullary nailing which has been practiced with success since the 1940ies by Gerhard Küntscher and colleagues for femoral shaft fractures with minimal complication rates and improved results after closed reduction. The era of retrograde femoral nailing began with the systematic approach through the intercondylar notch by Green. This paper reviews the biomechanical properties, indication, technique as well as potential hazards and pitfalls of fracture management with the AO "distal femoral nail" (DFN). With appropriate application this technique is suitable for all fractures of the distal third of the femoral shaft including highly instable bicondylar fractures without damage to the soft tissues and the knee joint.

    Full Text Available Introduction: We report the results of treating a series of 56 fractures in 54 elderly patients with a distal femur fracture with a retrograde femoral nail. Methods: Fifty-four of the nails were inserted percutaneously with a closed reduction. After surgery all patients were allowed to weight bear as tolerated. Four fractures were supported in a temporary external splint. Results: The mean age of patients was 80.6 years (range 51–103 years, 52/54 (96% were females. There were no cases of nail related complications and no re-operations were required. One patient was lost to follow up. The 30-day mortality was 5/54 (9.3% and the one year mortality was 17/54 (31.5%. Conclusions: Distal femoral nail fixation provides a good method of fixation allowing immediate mobilisation for this group of patients.

    2014-01-01

    Full Text Available Intramedullary nailing of metaphyseal and segmental tibia fractures can be technically challenging for a variety of reasons. Restoring length, alignment and rotation of the injured limb requires careful preoperative planning and meticulous attention to surgical technique, while avoiding common pitfalls. Understanding the deforming forces on the fracture segments and normal tibial osteology provides a background for recognizing the most common pitfalls when nailing these fractures. Many adjuncts for obtaining and maintaining fracture reduction while nailing have been described, including extended positioning, use of the femoral distractor, blocking screws, and provisional plating. We discuss these techniques as well as the role of intramedullary fixation for treating metaphyseal fractures with articular extension. The purpose of this paper is to describe the background and technique for a variety of operative tips and tricks to facilitate intramedullary nailing of metaphyseal and segmental tibia fractures.

    We describe a fifty-six-year old, Afro-descendent female patient showing dystrophy of her twenty nails and hyperchromic, asymptomatic macule on her face. Histopathological examination of the macule showed vacuolization of the basal layer, melanophages in the superficial dermis and lymphoplasmocytic inflammatory infiltrate. Nail biopsy revealed orthokeratotic hyperkeratosis and lichenoid inflammatory infiltrate. Lichen planus pigmentosus is an uncommon variety of lichen planus. It is characterized by typical hyperpigmented macules on the face and neck. Nail changes might be present in 10% of lichen planus cases, but no associations with lichen planus pigmentosus have been described. We report a case of lichen planus in twenty nails associated with lichen planus pigmentosus on the patient's face.

    The use of nonreamed interlocking tibial nails in the management of open fractures of the tibial shaft has gained wide acceptance. This technique has been reported to have reproducible good results with a low incidence of complications in Type I, Type II, and Type IIIA open tibial shaft fractures. The use of nonreamed nails in Type IIIB fractures continues to be a source of controversy. The treatment of 72 open fractures of the tibial shaft with nonreamed interlocking intramedullary nailing is detailed. There were 27 Type I, 22 Type II, 11 Type IIIA, and 12 Type IIIB open tibial shaft fractures. There were three (4.2%) deep infections; one Type II, one Type IIIA, and one Type IIIB. Forty-nine fractures (68%) united by 6 months, all fractures had united by 12 months. The use of nonreamed locking intramedullary nailing in Types I, II, IIIA, and IIIB open fractures of the tibial shaft is supported.

    Nail polishes are cosmetic paints that may be susceptible of forensic analysis offering useful information to assist in a crime reconstruction. Although the nail polish appearance could allow a quick visual identification of the sample, this analysis is subjected to the perception and subjective interpretation of the forensic examiner. The chemical analysis of the nail polishes offers great deal of information not subjected to analyst interpretation. Confocal Raman spectroscopy is a well-suited technique for the analysis of paints due to its non-invasive and non-destructive nature and its ability to supply information about the organic and inorganic components of the sample. In this work, 77 regular and gel nail polishes were analyzed with confocal Raman spectroscopy using two laser wavelengths (532 and 780 nm). The sample behavior under the two laser wavelengths and the differences in the spectra taken at different points of the sample were studied for each nail polish. Additionally, the spectra obtained for all the nail polishes were visually compared. The results concluded that the longer laser wavelength prevents sample burning and fluorescence effects; the similarity among the spectra collected within the sample is not directly related with the presence of glitter particles; and 64% of the samples analyzed showed a characteristic spectrum. Additionally, the use of confocal Raman spectroscopy for the forensic analysis of nail polishes evidence in the form of flakes or smudges on different surfaces were studied. The results showed that both types of evidence can be analyzed by the technique. Also, two non-invasive sampling methods for the collection of the evidence from the nails of the suspect or the victim were proposed: (i) to use acetone-soaked cotton swabs to remove the nail varnishes and (ii) to scrape the nail polish from the nail with a blade. Both approaches, each exhibiting advantages and drawbacks in terms of transport and handling were appropriate

    Anatomic reconstruction of the posterior facet by primary stabilization of the calcaneal fracture with a locking nail. All intraarticular calcaneal fractures and unstable two-part fractures independent of the degree of closed/open soft tissue trauma. High perioperative risk, soft tissue infection, beak fracture (type II fracture) and still open apophysis. Anatomic reduction of the posterior facet using a sinus tarsi approach. Reduction and temporary fixation of the sustentacular, tuberosity, and anterior process fragments with 1.8-2.0 mm Kirschner wires. Thereafter, the C-Nail (calcaneus nail) is introduced with its guiding device stabilizing the sustentacular, tuberostity, and anterior process fragments through its three guiding arms with 6 or 7 locking screws. Passive and active motion starts on postoperative day 2. Lymph drains help reduce swelling. Partial weightbearing with 20 kg for 6-8 weeks in the patient's own shoes is recommended. X‑ray controls are done at 4 and 8 weeks as well as after 6 and 12 months. A total of 107 calcaneal fractures treated with the C-Nail between 2011 and 2014 were evaluated according to the AOFAS score 6 months and 1 year after surgery. The measured values were on average 93.0 (range 65-100) points at 6 months and 94.1 (range 75-100) points 12 months after the surgery. Böhler's angle with initial traumatic values of 6.2° (-30 to +13°) improved postoperatively to 31.8°, after 3 months slightly decreased to 29.6°, and after 12 months to 28.3°. There were 2 cases of superficial wound necrosis (1.9 %) and 1 case a deep infection (0.93 %) with need of early C-Nail removal.

    Twenty-eight patients with open femoral shaft fractures treated by reamed intramedullary nailing were reviewed retrospectively. Nine patients had Gustilo Grade I injuries; 14, Grade II; and five, Grade IIIA. Twenty cases had static locking, two cases had dynamic locking, and six cases were not locked. Average time to union was 20 weeks. The infection and nonunion rates were 0%. The data suggest that interlocked reamed intramedullary nailing is a safe treatment option for treating open femoral shaft fractures.

    Transungual nail penetrance has traditionally been considered to be the only route of delivery for topical antifungals in onychomycosis. Subungual penetrance may be an alternate route of delivery. To evaluate the ability of efinaconazole vehicle solution to reach the site of toenail onychomycosis through application to the hyponychium or hyponychium and dorsal nail surface, and assess the impact of the air gap between the nail plate and nail bed. Twenty-three participants with moderate to severe, mycologically-confirmed onychomycosis were enrolled (mean age, 48.5 years). Two separate applications of vehicle solution containing fluorescein for visualization were applied at the hyponychium or hyponychium and dorsal nail surface. Affected nails were later clipped to allow examination of the nail bed and further examination of the ventral surface of the nail. Spread of formulation was assessed under visible and UV light conditions by photographing target toenails after vehicle application and after nail clipping. There was a positive correlation between the size of the air gap and degree of affected nail involvement (R2=0.064). Assessments under both visible and UV light indicated that the vehicle had spread to the site of infection, with deposition of fluorescein wherever vehicle had reached, irrespective of application methodology or size of air gap. Nail clippings also indicated absorption into the ventral surface of the nail plate. The relative contributions of subungual versus transungual application of drug to the nail plate to the efficacy of efinaconazole topical solution, 10% in treating onychomycosis were not assessed. This study suggests that the low surface tension vehicle developed for efinaconazole topical solution, 10% can reach the site of infection by application to the hyponychium, dorsal or ventral nail surface and nail folds. This multidirectional approach to drug delivery at the site of fungal infection may contribute to the magnitude of efficacy

    Full Text Available Aim: To study the functional and anatomical outcome of Inter trochanteric fractures of femur treated with Short femoral nail. Method: This was retrospective study carried out in which 60 patients (50 Male & 10 Female of 5th to 8th decade of life who underwent Short femoral nail fixation for both Stable & unstable Inter Trochanteric fractures. From the records each patient data was assessed for time required for mobilization, average fracture healing time, degree and grade of hip range of movements, complications, anatomical reduction achieved using Short femoral nail fixation. Results: 55 cases achieved Anatomical reduction. Good to Excellent Hip range of Motion was in 55 (90 % cases. Fracture union was seen in all cases. No evidence of Z Effect, AVN of femoral head, Implant failure, Fracture of femoral shaft below the Nail tip was seen in any case, However Reverse Z Effect was seen in 4 & shortening of less than 2 cm was seen in 2 cases, External rotation of 10 degree was seen in1 case. Average fracture Union time was 14 weeks. Conclusion: Short femoral nail appears to be better implant for fixation of both Stable & unstable Inter Trochanteric fractures as it fulfills the biomechanical demands being minimally invasive, less blood loss , it prevents excessive varus collapse at fracture site, produces less stress riser effect below the nail tip, Short operative time, Facilitates early mobilization & functional recovery of patients. But Anatomical fracture reduction & optimal implant placement are absolutely must for better results.

    Femoral shaft fractures are usually seen in the young population as a result of high energy traumas and are often accompanied by major organ injuries. In this paper, we aimed to assess the clinical results of expandable femoral intramedullary nails in the treatment of 20 femoral shaft fractures. The average age was 34.7. One fracture was the result of a gunshot wound, type 3A open fracture, and the other 19 fractures were closed. Under fluoroscopic control, all patients underwent elective closed reduction and internal fixation with intramedullary expandable femoral nails (Fixion, Disc-O-Tech; Israel). In case of failed or unacceptable closed reduction, open reduction was achieved with a second incision over the fracture site. Average operation time was 26.3 minutes. Full union was achieved in all patients. The shortest union time was 12 weeks and the longest 24 weeks, with an average of 15.2 weeks. Results in 15 patients (75%) were excellent, in 4 patients (20%) good and in 1 patient (5%) moderate according to Thorensen criteria. Use of expandable nails provides union without major complications and offers advantages such as less exposure to radiation as seen in distal locking of classical intramedullary nails. In conclusion, the good results of this study show that the expandable femoral intramedullary nail provides a successful option to classical intramedullary nails.

    2015-06-01

    Full Text Available Background: Toxic and hazardous heavy metals like arsenic, lead, mercury, zinc, chromium and iron are found in a variety of personal care products, e.g. lipstick, whitening toothpaste, eyeliner and nail color. The nails absorb the pigments of nail polishes and vaporized or soluble metals can easily pass it. The goal of this survey was to assess whether the different colors of nail polishes comply with maximum concentrations of heavy metals in the EPA’s guidelines. Methods: 150 samples of different popular brands of nail polishes in 13 colors (yellow, beige, silver, pink, white, violet, brown, golden, green, black, colorless, red and blue were randomly purchased from beauty shops in Tehran City, Iran, in 2014. Microwave digestion EPA method 3051 was used by a microwave oven to determine the amount of 5 heavy metals; Nickel, Chromium, Lead, Arsenic and Cadmium. One-way ANOVA, Two-way ANOVA, hierarchical cluster, and principal component analyses were applied by Statistica 7.0 software. Results: The concentrations of chrome, lead, nickel and arsenic showed significant differences between the colors (p<0.05. In all studied samples, the level of cadmium was beyond the safe maximum permissible limit (MPS, but no significance difference in the cadmium content was identified. Conclusion: Due to the high concentrations of toxic metals in many brands of nail polishes, meticulous quality control is recommended for these beauty products.

    Triphenyl phosphate (TPHP) is primarily used as either a flame retardant or plasticizer, and is listed as an ingredient in nail polishes. However, the concentration of TPHP in nail polish and the extent of human exposure following applications have not been previously studied. We measured TPHP in ten different nail polish samples purchased from department stores and pharmacies in 2013-2014. Concentrations up to 1.68% TPHP by weight were detected in eight samples, including two that did not list TPHP as an ingredient. Two cohorts (n=26 participants) were recruited to assess fingernail painting as a pathway of TPHP exposure. Participants provided urine samples before and after applying one brand of polish containing 0.97% TPHP by weight. Diphenyl phosphate (DPHP), a TPHP metabolite, was then measured in urine samples (n=411) and found to increase nearly seven-fold 10-14h after fingernail painting (pexposure, ten participants also painted their nails and painted synthetic nails adhered to gloves on two separate occasions, and collected urine for 24h following applications. Urinary DPHP was significantly diminished when wearing gloves, suggesting that the primary exposure route is dermal. Our results indicate that nail polish may be a significant source of short-term TPHP exposure and a source of chronic exposure for frequent users or those occupationally exposed.

    Allergic contact dermatitis (ACD) secondary to acrylates and methacrylates is a well- described occurrence, particularly in those who wear or handle gel nail varnish. Management involves avoidance of the identified allergen. The cause of chronic urticaria (CI) is often not identified, and CU is not known to be associated with acrylates or methacrylates. We report a case of a 50-year-old woman who initially presented with hand dermatitis exacerbated by gel nail varnish on a background of CU. Avoiding all nail varnishes because of her ACD also resulted in improvement of her CU. To our knowledge, this is the first documented case of CU secondary to the acrylates and methacrylates found in nail cosmetics. © 2017 British Association of Dermatologists.

    Full Text Available The nail is an important skin appendage, but not many dermatologists are aware of the importance it receives outside our specialty. This article focuses on the nail in non-dermatological contexts. The nail is a keratinized matrix capable of continuous growth with the ability to incorporate various compounds within its structure. Therefore it can be used to monitor long-term consumption of drugs. It is also an excellent source of germ-line DNA for genetic analyses. With an increased undrstanding of nail physiology, there is now a better understanding of its connection to various pathologies as well. Nails, being peripherally placed, are easy to sample without significant discomfort to the patient, making them a valuable diagnostic tool. For this narrative review, we carried out a PubMed search using the key words “nail clipping,” “nail DNA,” “nail diabetes mellitus;” “nail clipping oncology,” and “nail forensics”. Retrieved articles were searched for information pertaining to non-dermatologic uses of nail for evaluation, which is presented in a narrative fashion. It is clear from recent literature that the nail is not just an inert skin appendage, but a dynamic window into the ever-changing metabolic and genetic milieu. We highlight the numerous roles of nail specimens, as well as point towards future research needed therein.

  18. Carbon fiber intramedullary nails reduce artifact in postoperative advanced imaging

    2015-01-01

    This study assessed whether radiolucent carbon fiber reinforced-polyetheretherketone (CFR-PEEK) intramedullary nails decreased hardware artifact on magnetic resonance imaging (MRI) and computed tomography (CT) in vitro and in an oncologic patient population. In vitro and clinical evaluations were done. A qualitative assessment of metal artifact was performed using CFR-PEEK and titanium nail MRI phantoms. Eight patients with a femoral or tibial prophylactic CFR-PEEK nail were retrospectively identified. All patients had postoperative surveillance imaging by MRI, CT, and were followed for a median 20 months (range, 12-28 months). CFR-PEEK images were compared to images from a comparative group of patients with titanium femoral intramedullary nails who had a postoperative MRI or CT. A musculoskeletal-trained radiologist graded visualization of the cortex, corticomedullary junction, and bone-muscle interface, on T1-weighted (T1W), STIR, and contrast-enhanced T1-weighted fat-saturated (T1W FS) sequences of both groups with a five-point scale, performing independent reviews 4 months apart. Statistical analysis used the Wilcoxon rank-sum test and a weighted kappa. Substantially less MRI signal loss occurred in the CFR-PEEK phantom than in the titanium phantom simulation, particularly as the angle increased with respect to direction of the static magnetic field. CFR-PEEK nails had less MRI artifact than titanium nails on scored T1W, STIR, and contrast-enhanced T1W FS MRI sequences (p ≤ 0.03). The mean weighted kappa was 0.64, showing excellent intraobserver reliability between readings. CFR-PEEK intramedullary nail fixation is a superior alternative to minimize implant artifact on MRI or CT imaging for patients requiring long bone fixation. (orig.)

    We evaluated luliconazole nail solution, originally generated formulation, for the topical treatment of onychomycosis by two infection models. First, a suspension of Trichophyton mentagrophytes was dropped onto the ventral layer of human nail plate and these nails were set in Franz diffusion cells. After 9-day culture, luliconazole nail solutions (1, 3, and 5%) were applied to the dorsal surface of the nails once a day for 7 days. After application, fungal viability was assessed by measuring the ATP contents of the samples. The dose-dependent efficacy was confirmed, with 3% and 5% luliconazole nail solutions producing significantly lower ATP levels at 7-day treatment. When 3% and 5% luliconazole nail solutions were evaluated in a rabbit model of onychomycosis, both concentrations completely inhibited the recovery of fungi on culture after 4-week treatment. We therefore think these results indicate that 5% luliconazole nail solution is sufficiently potent for treatment of onychomycosis.

    To compare the frequency of nail biting in 4 settings (interventions) designed to elicit the functions of nail biting and to compare the results with a self-report questionnaire about the functions of nail biting. Randomised allocation of participants to order of conditions. University Psychology Department. Forty undergraduates who reported biting their nails. Left alone (boredom), solving maths problems (frustration), reprimanded for nail biting (contingent attention), continuous conversation (noncontingent attention). Number of times the undergraduates bit their nails. Nail biting occurred most often in two conditions, boredom and frustration. Nail biting in young adults occurs as a result of boredom or working on difficult problems, which may reflect a particular emotional state. It occurs least often when people are engaged in social interaction or when they are reprimanded for the behavior.

    Full Text Available Onychomycosis is a common nail ailment associated with significant physical and psychological morbidity. Increased prevalence in the recent years is attributed to enhanced longevity, comorbid conditions such as diabetes, avid sports participation, and emergence of HIV. Dermatophytes are the most commonly implicated etiologic agents, particularly Trichophyton rubrum and Trichophyton mentagrophytes var. interdigitale, followed by Candida species and non dermatophytic molds (NDMs. Several clinical variants have been recognized. Candida onychomycosis affects fingernails more often and is accompanied by paronychia. NDM molds should be suspected in patients with history of trauma and associated periungual inflammation. Diagnosis is primarily based upon KOH examination, culture and histopathological examinations of nail clippings and nail biopsy. Adequate and appropriate sample collection is vital to pinpoint the exact etiological fungus. Various improvisations have been adopted to improve the fungal isolation. Culture is the gold standard, while histopathology is often performed to diagnose and differentiate onychomycosis from other nail disorders such as psoriasis and lichen planus. Though rarely used, DNA-based methods are effective for identifying mixed infections and quantification of fungal load. Various treatment modalities including topical, systemic and surgical have been used.Topically, drugs (ciclopirox and amorolfine nail lacquers are delivered through specialized transungual drug delivery systems ensuring high concentration and prolonged contact. Commonly used oral therapeutic agents include terbinafine, fluconazole, and itraconazole. Terbinafine and itraconazole are given as continuous as well as intermittent regimes. Continuous terbinafine appears to be the most effective regime for dermatophyte onychomycosis. Despite good therapeutic response to newer modalities, long-term outcome is unsatisfactory due to therapeutic failure, relapse

    We performed a prospective randomised trial on matched groups of patients with displaced tibial shaft fractures to compare conservative treatment with closed intramedullary nailing. The results showed conclusively that intramedullary nailing gave more rapid union with less malunion and shortening. Nailed patients had less time off work with a more predictable and rapid return to full function. We therefore consider that closed intramedullary nailing is the most efficient treatment for displaced fractures of the tibial shaft.

    2013-09-01

    We report on three cases of subtrochanteric femoral fractures during trochanteric intramedullary nailing for the treatment of femoral shaft fractures. Trochanteric intramedullary nails, which have a proximal lateral bend, are specifically designed for trochanteric insertion. When combined with the modified insertion technique, trochanteric intramedullary nails reduce iatrogenic fracture comminution and varus malalignment. We herein describe technical aspects of trochanteric intramedullary nailing for femoral shaft fractures to improve its application and prevent implant-derived complications.

    Purpose of study was to compare nail alignment, incidence of stress riser and fracture with straight and curved nails of different lengths. We conducted a retrospective review of consecutive, initially 13 straight and subsequently 15 curved nails implanted in 17 men and 11 women. Angles of incidence and reflection subtended by nail tip with inner tibial cortex were measured. Cortical hypertrophy was assessed on follow-up radiographs. Angles of incidence and reflection were greater with short straight nails, less with long straight nails and stayed close to zero with long curved nails. Stress fractures occurred in 2 patients with straight nails at the level of the proximalmost tibial screw. Cortical hypertrophy was present in 7 patients with straight nails and in only 1 patient with a curved nail (p=0.01). Both nail length and inbuilt valgus contribute to better central positioning within the tibia. However, cortical stress reactions occur less frequently with curved nails.

    2013-07-01

    Full Text Available Introduction: Nail infection like onychomycosis is mainly caused by dermatophytes and account for almost half of all nail disorders. Prevalence of nail infection has been attributed to several factors such as age, gender, socioeconomic status and predisposition to diabetes amongst others. This study aims at determining the prevalence and level of awareness of non-diabetics towards nail infections in Mauritius.Material and Methods: A survey was carried out among 471 participants of the non-diabetic population of Mauritius. Data on socio demographic factors, awareness, level of hygiene, family history and quality of life were obtained via questionnaire based studies. Data was analysed using the SPSS software.Results: Results show almost the same ratio of female to male was affected with nail infection but varies gender wise. Participants within the age group 20-60 with less than US 500 monthly income had a higher incidence of nail infection. No significant relation was obtained between nail infection and education level. A significant relationship was obtained between nail infection and occupation as well as quality of life. More than half of participants did not know about the routes of nail infections or the precautions needed to avoid spreading. However, good level of hygiene was observed among the participants.Conclusion: Factors like age, gender and socio economic status had a significant relationship on nail infection. Nail infection affects the Quality of Life (QoL and manual workers or even professionals are prone to nail infections.

    Objective: To determine the outcome of intramedullary interlocking surgical implant generation network (SIGN) nail in diaphyseal tibial fractures in terms of union and failure of implant (breakage of nail or interlocking screws). Study Design: Case series. Place and Duration of Study: Orthopaedics and Spinal Surgery, Ghurki Trust Teaching Hospital, Lahore Medical and Dental College, Lahore, from September 2008 to August 2009. Methodology: Fifty patients aged 14 - 60 years, of either gender were included, who had closed and Gustilo type I and II open fractures reported in 2 weeks, whose closed reduction was not possible or was unsatisfactory and fracture was located 7 cm below knee joint to 7 cm above ankle joint. Fractures previously treated with external fixator, infected fractures and unfit patients were excluded. All fractures were fixed with intramedullary interlocking SIGN nail and were followed clinically and radiographically for union and for any implant failure. Results: Forty one (88%) patients had united fracture within 6 months, 5 (10%) patients had delayed union while 4 (8%) patients had non-union. Mean duration for achieving union was 163 + 30.6 days. Interlocking screws were broken in 2 patients while no nail was broken in any patient. Conclusion: Intramedullary interlocking nailing is an effective measure in treating closed and grade I and II open tibial fractures. It provides a high rate of union less complications and early return to function. (author)

    There are no guidelines regarding the management of scabies in infants and recurrence is common at this age. We report the case of an infant with subungual hyperkeratosis and ungual lesions subsequent to classic scabies. A 7-month-girl, treated 6 weeks earlier with esdepallethrin for scabies, consulted for acquired lesions on 3 toe nails. These nails were thickened and displayed subungual hyperkeratosis. Physical examination of the skin, the finger nails and mucous membranes was otherwise normal. Fungal analyses were negative, but direct microscopic examination revealed numerous larvae of Sarcoptes scabiei as well as ovular debris. The child was treated with urea 40% to obtain chemical avulsion of the nails, and with topical esdepallethrin and a quarter tablet of ivermectin orally; there was no follow-up of the child. Ungual scabies has already been reported in crusted scabies and very rarely in classic scabies. Subungual and ungual locations of S. scabiei may constitute a source of reinfestation with scabies in infants. Treatment is not well defined and currently involves chemical avulsion of the nails and the application of topical antiscabies treatment. Copyright © 2016. Published by Elsevier Masson SAS.

    Onychomycosis is a common problem. Obtaining accurate laboratory test results before treatment is important in clinical practice. The purpose of this study was to compare results of curettage and drilling techniques of nail sampling in the diagnosis of onychomycosis, and to establish the best technique and location of sampling. We evaluated 60 patients suffering from distal and lateral subungual onychomycosis and lateral subungual onychomycosis using curettage and vertical and horizontal drilling sampling techniques from three different sites of the infected nail. KOH examination and fungal culture were used for detection and identification of fungal infection. At each sample site, the horizontal drilling technique has a better culture sensitivity than curettage. Trichophyton rubrum was by far the most common pathogen detected by both techniques from all sampling sites. The drilling technique was found to be statistically better than curettage at each site of sampling, furthermore vertical drilling from the proximal part of the affected nail was found to be the best procedure for nail sampling. With each technique we found that the culture sensitivity improved as the location of the sample was more proximal. More types of pathogens were detected in samples taken by both methods from proximal parts of the affected nails.

  19. Elastoplasticity analysis of the nails used in long bone fractures

    2011-01-01

    Elastoplastic endomedullary nail-insertion system in long bone fractures is a method which allows generating forces, moments, frictions and stress states in parts of the bone previously selected. Adding previous knowledge on the distribution of forces and acting moments over the bone fragments to be threaded, as well as on the elastoplastic and mechanical properties of the nails to be inserted (designing a special, specific structure for each case), the results, coming from 26 years of applying this technique, have been promising. It is from this perspective that we call this threading and anchoring procedure 'Selective Tension System' (STS). Physicochemical analyses and mechanical trials on elastoplastic nails used in the osteosynthesis in long bone fractures are presented. The magnitude of the forces produced by flattening the nails and the reacting forces at both ends are measured. It is expected that the evidence provided on the elastic variability of these nails will be useful as guidance on the availability and choice of the elastoplastic combinations that best fit each patient.

    1998-01-01

    A total of 33 patients submitted to tibial intramedullary osteosynthesis for fracture (27 cases) and non-union were assessed by ultrasound and x-rays an average of 10.9 months after surgery. The route of access was patellar transtendineal in each case; the means of synthesis used was the Marchetti Vicenzi nail. In 19 patients (57.6%) there was anterior gonalgia. Radiologic assessment evaluated prominence of the nail, while nail-tendon impingement was examined by ultrasound. Nail-tendon impingement was frequently observed (24 cases, 72.7%); in cases such as these anterior pain in the knee was present in 17 patients: however, this fact did not achieve statistical significance. The patellar tendon was thickened as compared to the contralateral one, with disorganization of the fibrillar echotexture, but it was not shortened. The tendinous morphostructure did not reveal any relationship with anterior gonalgia. In none of the cases did we observe the formation of scarring nuromas. In the area of the Hoffa body reactive synovitis phenomena with structural hyperechogenicity, an unclear aspect of the posterior tendinous profile and calcifications were observed. Radiographic prominence of the nail was correlated with echographic impingement, but not with clinical findings. Removal of the instrumentation carried out in 8 patients characterized by anterior gonalgia did not lead to resolution of symptoms in 2 cases in which MRI study showed patellar tendinitis and in 1 case patellar chondropathy with irregularity of the Hoffa body in the second.

    Duwelius, P J; Schmidt, A H; Rubinstein, R A; Green, J M

    1995-06-01

    Forty-nine acute displaced tibial fractures (31 closed, 18 open: 5 Grade I, 7 Grade II, 4 Grade IIIA, and 2 Grade IIIB) were treated in 1 community with a standard operative protocol using a distractor without a fracture table, and an unreamed interlocked tibial nail. Forty-six fractures healed (94%). Complications included 3 nonunions (6%), 2 deep infections (4%), 9 delayed unions (18%), 4 angular malunions (8%), 2 rotatory malunions (4%), and 12 interlocking screws bent or broke (24%). Twenty-eight patients (57%) required at least 1 additional operation to obtain union, most commonly dynamization of a statically locked nail. The authors conclude that unreamed tibial nails provide adequate stabilization of displaced tibial fractures and can be used in the management of most open or closed tibial fractures. However, static locking is required in axially unstable fractures. Early dynamization or exchange nailing and bone grafting should be considered to hasten union and avoid screw failure. The distractor is an excellent adjunctive technique for reduction and alignment of tibial shaft fractures during intramedullary nailing.

  2. Semiextended position of intramedullary nailing of the proximal tibia.

    1996-07-01

    Over a 24 month period, 30 patients with proximal tibia fractures who were reviewed consecutively were treated by nonreamed, statically locked, intramedullary nailing. There were 16 open, 13 segmental, and 7 comminuted fractures (Winquist III, IV). The average distance from the fracture to the proximal locking screws was 24 mm (range, 0-65 mm). All procedures were performed while the patient's affected leg was on a radiolucent table without traction. The last 25 fractures were nailed using a partial (2/3) medial parapatellar incision while the leg was semiextended. This approach allowed the patella to be subluxed laterally availing the trochlear groove for use as a conduit for nail placement. Using only 15 degrees knee flexion eliminated the extension force of the quadriceps on the proximal fragment, which otherwise would have tended to cause anterior angulation at the fracture site. In the first 5 patients, the average anterior angulation was 8 degrees (range, 5 degrees-15 degrees). Of the 25 patients who were treated while in the semiextended position, none had more than 5 degrees anterior angulation and 19 had no anterior angulation. Fractures of 3 of the 25 patients had greater than 5 degrees angulation in the coronal plane, 2 of which were nailed in the semiextended position. This technique greatly facilitates intramedullary nailing of proximal tibia fractures.

    In many low and middle-income countries (LMICs) SIGN nail is commonly used for antegrade femoral intramedullary (IM) nailing, using a start site either at the tip of the greater trochanter or piriformis fossa. While a correct start site is considered an essential technical step; few studies have evaluated the impact of using an erroneous start site. This is particularly relevant in settings with limited access to fluoroscopy to aid in creating a nail entry point. The purpose of this study was to evaluate the impact of antegrade SIGN IM nailing start site on radiographic alignment and health-related quality of life. In this prospective cohort study, adult patients with proximal femur fractures (OTA 32, subtrochanteric zone) treated with antegrade IM SIGN nail at Muhimbili Orthopaedic Institute (MOI), Dar es Salaam, Tanzania were enrolled. Start site was determined on the immediate postoperative X-ray and was graded on a continuous scale based on distance of the IM nail center from the greater trochanteric tip. The primary outcome measurement was coronal alignment on the post-operative x-ray. The secondary outcomes were reoperation rates, RUST scores and EQ5D scores at one year follow-up. Seventy-nine patients were enrolled. 50 of them (63.3%) had complete data at 1year and were included in the final data analysis. Of the fifty patients, nine (18%) had IM nails placed laterally, 26 (52%) medially and 15 (30%) directly over the tip of the greater trochanter. Compared to a start site at the tip or medial to the greater trochanter, a lateral start site was 9 times more likely to result in a varus malalignment (95% CI: 1.42-57.70, p=0.021). Lateral start site was associated with varus malalignment. Although lateral start site was not significantly associated with reoperation, varus deformity was associated with higher reoperation rates. Surgeons should consider avoiding a start site lateral to the tip of the greater trochanter or allow the nail to rotate to avoid

    We classified human femoral intramedullary architecture into 3 types. The cortex in the first type is thick and the medullary canal narrow with an even and smooth translation towards the metaphysis. In the second type, the cortex is thin and the canal wider, also evenly distributed along the entire length, while in the third type the canal narrows just distal to the subtrochanteric region and similarly a few centimeters distally. Some medullary canals of the second type do not allow dynamic nailing, while canals of the third type presents some difficulties for unreamed nails. Most medullary canals belong to the first and second type and only few belong to type three. We performed comparative experimental loading in 11 pairs of cadaveric fractured femora fixed with static and dynamic nailing. Dynamic nailing was found to behave as safely as static ones in the presence of a sound femoral shaft central and peripheral to the fracture with a length twice the diameter of the femur at the fracture level. This could be checked intraoperatively with gentle rotation under image intensifier. In a clinical series, dynamic nailing was performed in about one quarter of the patients with femoral shaft fractures (18 of 72 patients) with excellent results.

    Full Text Available Background: Fractures of tibia are among the commonest fractures sustained in road traffic accidents. They are frequently open and contaminated. Unreamed nails are considered superior to external fixator in the management of open fractures of tibia. Method: Forty patients with open fractures of tibia, grade I, II, IIIa, IIIb were included in the study. They were managed by primary unreamed intramedullary nailing with adequate soft tissue management. Results: Functional results were excellent in 26 cases, good in 10 cases and fair in 4 cases. Four cases had delayed union. Average time of union was 16.9 weeks. Conclusion: Primary unreamed intramedullary nailing offers advantage of rigid fixation, low incidence of infection, non-union, good functional results and early return to work. An adequate soft tissue management is mandatory in treatment of these fractures.

    Full Text Available Eccrine syringofibroadenoma (ESFA is a rare, benign tumor of eccrine sweat gland origin that usually presents as a nodule on the extremities of an elderly person. It can also present as an ulcerative plaque, verrucous lesion, papular or nodular lesion or as palmoplantar keratoderma. Although the clinical features are variable, histology is characteristic in the form of anastomosing strands, cords and columns of epithelial cells embedded in a fibrovascular stroma. We report the case of a 62-year-old male with a nodular lesion on the extremity that caused secondary involvement of the nail in the form of complete nail dystrophy. The histology showed features consistent with ESFA. Nail involvement by ESFA is a rare presentation and is rarely described in the literature.

  11. A novel intramedullary nail for micromotion stimulation of tibial fractures.

    LENUS (Irish Health Repository)

    Dailey, Hannah L

    2011-09-20

    BACKGROUND: Animal studies and clinical trials have suggested that early application of controlled axial micromotion can accelerate healing of long bone fractures compared to rigid fixation. However, experimental investigations of micromotion constructs have been limited to external fixators, which have a higher incidence of complications than intramedullary nails. The purpose of this study was to assess whether a novel intramedullary nail design can generate stimulatory micromotion under minimal weight-bearing loads typical of the early healing period. METHODS: Eight cadaver tibiae were reamed, osteotomised, and implanted with commercially-available IM nails fitted with a custom insert that allowed 1mm of axial micromotion after proximal\\/distal interlocking. Specimens were mounted in a materials testing machine and subjected to cyclic axial loading while interfragmentary motion was measured using an extensometer. Implants were also tested in standard statically-locked mode. FINDINGS: The average force required to cause distraction of the fracture gap in micromotion mode was 37.0 (SD 21.7) N. The mean construct stiffness was 1046.8 (SD 193.6) N\\/mm in static locking mode and 512.4 (SD 99.6) N\\/mm in micromotion mode (significantly different, P<0.001). INTERPRETATION: These results support the development of a micromotion-enabled IM nail because the forces required to cause interfragmentary movements are very low, less than the weight of the hanging shank and foot. In contrast to rigid-fixation nails, which require significant weight-bearing to induce interfragmentary motion, the micromotion-enabled nail may allow movement in non-weight-bearing patients during the early healing period when the benefits of mechanical stimulation are most critical.

    The care of the patient with the fractured femur entails a multiple surgical team approach. Healing of the fracture and expediency in the operating room are both important. We sought to determine the results of the treatment of fractures of the femoral shaft with interlocking femoral nails inserted with closed techniques, and to compare the outcomes of fractures nailed by using a fracture table with those stabilized with the leg draped free on a radiolucent table. Eight hundred eighty-two consecutive patients with fractures of the femoral shaft treated with a first-generation intramedullary nail at the authors' institution during the years 1986 to 1996 were identified. Five hundred fifty-one fractures in 515 patients met the inclusion criteria. Treatment with an intramedullary nail led to a union rate of 98.9%. There were six infections, all occurring in closed fractures. Thirty-eight percent of the fractures had hardware removed, most commonly because of pain. One nail and 13 locking bolts broke. Four hundred eighteen fractures had adequate radiographs available to assess fracture alignment. No fracture healed with more than 10 degrees of angulation in either plane. Forty-four fractures healed with more than 5 degrees of angulation. A distal third fracture was found to be associated with an increased incidence of malalignment. There were no differences in outcomes between fractures stabilized with or without a fracture table. Reamed intramedullary nailing of femoral shaft fractures results in a low rate of nonunion, malunion, infection, and hardware failure. There is no difference in the outcomes of fractures treated with and without the use of a fracture table. This is particularly useful in the patient with multiple injuries for whom transfer to a fracture table may not be time effective.

    The purpose of this study is to characterize samples of human nails, subjected to irradiation of high doses through Technical Electron Paramagnetic Resonance (EPR). The goal is to establish a dose/response relationship in order to assess dose levels absorbed by individuals exposed in radiation accidents situations, retrospectively. Samples of human nails were irradiated with gamma radiation, and received a dose of 20 Gy. EPR measurements performed on samples before irradiation identified EPR signals associated with defects caused by the mechanical action of the sample collection. After irradiation other species of free radicals, associated with the action of gamma radiation, have been identified

    Though brushes are no longer used on the hands and forearms during the surgical scrub, they are still widely used on the nails. The aim of this study was to determine whether nail picks and nail brushes are effective in providing additional decontamination during a surgical hand scrub. A total of 164 operating department staff were randomised to undertake one of the following three surgical hand-scrub protocols: chlorhexidine only; chlorhexidine and a nail pick; or chlorhexidine and a nail brush. Bacterial hand sampling was conducted before and 1h after scrubbing using a modified version of the glove juice method. No statistically significant differences in bacterial numbers were found between any two of the three intervention groups. Nail brushes and nail picks used during surgical hand scrubs do not decrease bacterial numbers and are unnecessary.

  16. An in vivo evaluation of surface polishing of TAN intermedullary nails for ease of removal

    Directory of Open Access Journals (Sweden)

    JS Hayes

    2009-09-01

    Full Text Available Fractures of the tibia and femoral diaphysis are commonly repaired by intra-medullary (IM nailing. Currently IM nails are available in either electropolished stainless steel (SS or in Titanium-Aluminium-Niobium (TAN. After healing, removal of the nails still is common but removal of TAN IM nails often has complications whereas SS IM nails of the same design are less often associated with problems. We believe the differences in removal are due to the ability of TAN to promote strong bone on-growth. We have previously shown in vivo that polishing cortical screws reduces removal torque and the percentage of bone-implant contact. Therefore, we postulate that bony on-growth onto IM nails can be reduced by means of surface polishing, for ease of removal. Here we aim to compare the pull-out forces for removal of standard TAN (TAN-S compared to experimental paste polished TAN (TAN-PP IM nails from a bilateral non-fracture sheep tibia model after 12 months implantation. Histological analysis was also performed to assess tissue on-growth to the nails. We show that polishing significantly reduces (p=0.05 the extraction force required for TAN IM nail removal. This effect in part is attributable to the distinct tissue-material reaction produced. For TAN-S nails direct bone contact was observed while for TAN-PP nails a fibrous tissue interface was noted. Since TAN is preferred over SS for IM nailing due to superior biocompatibility and mechanical properties, we believe these findings could be used to recommend changes to current surface technologies of intramedullary nails to reduce complications seen with nail removal especially in rapidly growing bone in children.

  17. Early experience with titanium elastic nails in a trauma unit.

    2012-02-03

    The Titanium Elastic Nail (TEN) offers a number of potential advantages over traditional ways of treating long bone fractures particularly in the paediatric population. These advantages include earlier mobilisation and shorter hospital stay and less risk of loss of fracture position. These advantages are most apparent and significant when treating femoral fractures in children where the length of hospital stay is reduced from several weeks to a typical period of 5 to 8 days. We have reviewed our early experience of using these implants over the past 2 years. Patients were assessed clinically and radiologically. 13 patients were treated using the TEN during this period. There were 2 femoral fractures, 4 humeral fractures, 1 tibial and 6 forearm fractures treated using the Titanium Elastic Nail. All fractures united during the study period. However 1 humeral fracture required a secondary bone grafting and plating for delayed union and 1 fracture lost position during follow-up. Insertion point pain was a problem in 4 patients but this resolved after nail removal in all. There was 1 superficial wound infection which resolved with antibiotics and 1 superficial wound infection of an open fracture wound which resolved following nail removal and antibiotics. There were no cases of deep infection. There were no limb length discrepancy or rotational or angular malalignment problems. Biomechanical principles and technical aspects of this type of fixation are discussed.

    Hand-foot-mouth disease (HFMD) is a viral disease that is characterized by palmoplantar vesicular eruption and erosive stomatitis. Beau's line and onychomadesis can be observed as late findings following HFMD due to arrest in nail matrix. We aimed to draw attention to HMFD and nail changes, which have been seen more frequently. Demographic characteristics and nail findings of 15 children, who were diagnosed with HFMD in the dermatology clinic of Beykoz State Hospital between August 2015-October 2015 were evaluated. Mean age of the patients was 5.13 years (1-13 years), 66.6% were boys (n=10), and 33.4% were girls (n=5); 53.3% were diagnosed in August (n=8). Dermatologic examinations revealed palmar and plantar vesicular eruptions in all cases, additionally one patient had vesicular eruptions also on hip, legs, and arms. Erosive stomatitis was present in oral mucosa of 60% of patients (n=9). Nail findings were determined after a mean of 4.06 weeks following HFMD. Onychomadesis and Beau's line were present in 66.6% (n=10) and 33.4% of the patients, respectively. Hand-foot-mouth disease is a viral infection of childhood, which may be seen as isolated cases or epidemics, and characterized with palmoplantar vesicular eruption and erosive stomatitis. Being aware that Beau's line and onychomadesis can be seen as late findings of HFMD and should relieve without treatment, will prevent unnecessary diagnostic and invasive interventions.

    2008-01-01

    Full Text Available Background: Proximal phalangeal fractures are commonly encountered fractures in the hand. Majority of them are stable and can be treated by non-operative means. However, unstable fractures i.e. those with shortening, displacement, angulation, rotational deformity or segmental fractures need surgical intervention. This prospective study was undertaken to evaluate the functional outcome after surgical stabilization of these fractures with joint-sparing multiple intramedullary nailing technique. Materials and Methods: Thirty-five patients with 35 isolated unstable proximal phalangeal shaft fractures of hand were managed by surgical stabilization with multiple intramedullary nailing technique. Fractures of the thumb were excluded. All the patients were followed up for a minimum of six months. They were assessed radiologically and clinically. The clinical evaluation was based on two criteria. 1. total active range of motion for digital functional assessment as suggested by the American Society for Surgery of Hand and 2. grip strength. Results: All the patients showed radiological union at six weeks. The overall results were excellent in all the patients. Adventitious bursitis was observed at the point of insertion of nails in one patient. Conclusion: Joint-sparing multiple intramedullary nailing of unstable proximal phalangeal fractures of hand provides satisfactory results with good functional outcome and fewer complications.

    Nowadays pediatric femoral fractures are more commonly managed with operative treatment rather than conservative treatment because of more rapid recovery and avoidance of prolonged immobilization. Children between the ages of 5-13 years are treated either by traction plus hip spica and flexible/elastic stable retrograde intramedullary nail, or external fixators in the case of open fractures. The aim of this study is to evaluate the outcome of pediatric femoral shaft fractures treated by stainless steel flexible intramedullary nail in children between 5 and 13 years of age. There were 32 cases of femoral shaft fractures which were all fixed with stainless steel flexible intramedullary nail under fluoroscopy. Long leg cast was applied at the time of fixation. Partial weight bearing was started 2 weeks after surgery. Patients were evaluated in follow-up study to observe the alignment of fracture, infection, delayed union, nonunion, limb length discrepancy, motion of knee joint, and time to unite the fracture. We were able to follow up 28 out of 32 patients. The patients were 8.14 years of age on average. The mean hospital stay after operation was 4 days and fracture union time was 9.57 weeks. There were 3 cases of varus angulation, 2 cases of anterior angulation, and 4 cases of limb lengthening. Patients aged between 5 and 13 years treated with flexible intramedullary nail for closed femoral shaft fracture have rapid union and recovery, short rehabilitation period, less immobilization and psychological impact, and cost-effective.

    The aim of this study was to assess probabilistic exposure to nail cosmetics in French consumers. The exposure assessment was performed with base coat, polish, top coat and remover. This work was done for adult and child consumers. Dermal, inhalation and oral routes were taken into account for varnishes. Exposure evaluation was performed for the inhalation route with polish remover. The main route of exposure to varnishes was the ungual route. Inhalation was the secondary route of exposure, followed by dermal and oral routes. Polish contributed most to exposure, regardless of the route of exposure. For this nail product, P50 and P95 values by ungual route were respectively equal to 1.74 mg(kg bw week)(-1) and 8.55 mg(kg bw week)(-1) for women aged 18-34 years. Exposure to polish by inhalation route was equal to 0.70 mg(kg bw week)(-1) (P50) and 5.27 mg(kg bw week)(-1) (P95). P50 and P95 values by inhalation route were respectively equal to 0.08 mg(kg bw week)(-1) and 1.14 mg(kg bw week)(-1) for consumers aged 18-34 years exposed to polish remover. This work provided current exposure data for nail cosmetics, and a basis for future toxicological studies of the uptake of substances contained in nail cosmetics in order to assess systemic exposure.

    Full Text Available Aim: The superior gluteal nerve may be compromised during hip surgery. We retrospectively evaluated the patients who underwent proximal femoral nailing for unstable trochanteric fractures in order to investigate the presence of superior gluteal nerve injury and its clinical findings. Material and Method: Twenty five patients (14 women, 11 men were included in the study who had femoral nailing between January 2004 and March 2010 at Hamidiye Sisli Etfal Training and Research Hospital Department of Orthopaedics. Two different types of nails which have similar designs and surgical techniques were used for fracture fixation. Patients who had a history of cerebrovascular disease, electromyography findings of polyneuropathy, or degenerative vertebral disease were excluded from the study. Patients were evaluated clinically and radiologically. Findings related to acute denervation in the gluteus medius muscle and motor unit action potential changes were accepted as signs of superior gluteal nerve injury. Results: Eight patients were using support during walking and three of these patients had positive Trendelenburg sign, but only one patient had acute denervation signs of the superior gluteal nerve. Discussion: Based on the present study the incidence of iatrogenic nerve injury is a rare complication of proximal femoral nailing. Elderly patients, regardless of whether they have nerve injury, may limp and need to use a walking support.

    Antegrade or retrograde intramedullary nailing is a common and well established procedure for the treatment of femoral shaft fractures. One drawback of this technique is the high incidence of clinically relevant malalignment. Despite intra-operative and radiological improvements this problem has not yet been solved efficiently. The aim of this study was the evaluation of the mechanical influence on the antetorsion angle of intramedullary nails during and after interlocking in femoral shaft fractures. A mechanical instrument was developed allowing a defined torque to be administered to the distal femur fragment. As an optical measurement system for the assessment of the antetorsion angle, a navigation system was applied. Initially the influence of the interlocking mechanism of the nail on the antetorsion deviation was investigated. The distal interlocking hole was fixed free handed or by using a navigation system. The multidirectional movement of the distal femur fragment was documented. Furthermore, the influence of the rotational stability on the antetorsion angle after mechanical stress of 4 NM was investigated by measuring the remaining rotational capacity of the distal femur fragment. The average remaining rotational capacity of the distal femur fragment was 5.8 degrees after locking the nail by hand. The navigated locking resulted in a deviation of only 2 degrees , a significant difference compared to the free-hand procedure. The rotational stability under stress showed an average of 15.4 degrees deviation of the distal fragment. Even after complete interlocking of the intramedullary nail a 14.2 degrees rotational deviation was observed. It could be shown that mechanical stability as well as the interlocking itself of femoral nails have a relevant impact on the antetorsional angle of the femur. Potential sources of error of the femoral antetorsion angle can be caused by the interlocking process as well as by forced rotation of the femur after interlocking

    Full Text Available 【Abstract】Objective: To assess the value of ankle fusion with a retrograde locked intramedullary nail in the treatment of sequela of lower extremity compartment syndrome. Methods: Thirty-five cases of equinus deformity follow-ing tibiofibular compartment syndrome treated by means of ankle fusion with a retrograde locked intramedullary nail from January 2001 to December 2010 were retrospectively reviewed. The complications, the time needed for bony fu-sion of the ankle joint assessed by anteroposterior and lateral X-ray photographs as well as patients’ subjective evalua-tion were recorded and analysed. Results: Among the 35 patients, 15 had previously undergone surgical treatment twice on the same limb, 13 had thrice and 7 had to be operated on four times before ankle fusion. An anterior midpoint approach to the ankle joint was adopted in 29 cases, while anterior midpoint ap-proach plus a small incision on the posterior ankle joint was made in 17 cases, whereas lateral approach in 6 cases. Tar-sus joint fusion was performed on 4 cases. The follow-up period ranged 6-124 months, averaged 40.6 months. Bone grafting was not performed in this series. Preoperative tibial shaft fracture occurred in one patient and was healed after conservative treatment. Incision dehiscence located at pre-vious Achilles tendon incision was found in two patients. As a result, one received an intramedullary nail emplace-ment at calcaneoplantar part while the wound at anterosuperior part of the other one was healed by dressing change. Two patients failed to bony union 5 months postoperatively, in which one healed 10 weeks after retrieval of proximal tibial nail and another by iliac grafting. Terminal necrosis of the toe due to blood supply dysfunction was not found in this series. All the patients were satisfied with the ankle joint function postoperatively. The time for bony union on X-rays was 9.8 weeks on average. Except for one patient who demanded removal of

    The incidence of trochanteric fractures has increased significantly during the last few decades, especially in elderly patients with osteoporosis. The dynamic/sliding hip screw and the cephalomedullary nail are the most commonly used fixation methods to treat trochanteric fractures. The improvements in the Gamma Nail System (GNS) associated with a correct surgical technique reduced the postoperative orthopedic complications. The purpose of this study was to compare the results of the different Gamma Nails. The present study is a retrospective analysis of 2144 patients treated with GNS between January 1997 and December 2011 for trochanteric fractures, classified according to AO classification method. The patients were divided into three groups according to the nailing system: 525 were treated with Standard Gamma Nail (SGN), 422 with Trochanteric Gamma Nail (TGN) and 1197 with Gamma3 Nail. The overall incidence of intra-operative complications was 1.21 %; the incidence of intra-operative complications for each group was 1.71 % for SGN group, 0.47 % for TGN group and 1.25 % for Gamma3 Nail group. The overall incidence of postoperative complications was 5.48 %, and the incidence for each group was 10.73 % for SGN group, 9.92 % for TGN group and 2.92 % for Gamma3 Nail group. The GNS is a safe device with a low rate of intra-operative complications. The evolution of this nail system reduces postoperative complications, thus improving the results at follow-up and confirming that the Gamma3 Nail is a safe and predictable device to fix trochanteric fracture.

    The basic principle of non-surgical fracture treatment is to restore the original anatomical position of fractured fragments by different techniques, without direct access to the bone and without further traumatizing of tissues. Intramedullary nailing is synthesis and consolidation of fracture fragments with the main goal to gain strength and permanent placement of the implants. Two techniques of intramedullary osteosynthesis are used: with dynamic or with static intramedullary nail. Dynamization include conversion of static nail by removing screws from the longest fragment. The aim of this study is to determine whether there is a difference in the speed and quality of healing of the type A and B fractures of the femur and tibia treated by static or dynamic intramedullary nails and to compare the results. The study was conducted at the Clinic for Orthopaedics and Traumatology, Clinical Center University Sarajevo from January 2004 to June 2009. The study was retrospective-prospective, manipulative, controlled and it was conducted on a total of 129 patients with closed fractures of the diaphysis of the femur and tibia type A and type B, with different segments of bone, regardless of sex and age structure, with the exception of children under 14 years of age. Precisely there were 47 patients with femoral fractures and 82 patients with tibial fractures. The average number of weeks of healing femoral and tibial fractures was slightly in advantage of static intramedullary osteosynthesis, it was 17.08 weeks (SD=3.382). The average number of weeks of healing in 23 patients with fractures of the femur, treated by dynamic intramedullary osteosynthesis was 17.83 (SD=2.978). We can conclude that static intramedullary nailing osteosynthesis unable movements between fragments which directly stimulates bone formation and formation of minimal callus. Static intramedullary osteosynthesis resolve the problem of stabilizing the fracture, limb shortening and rotation of fragments.

    • BACKGROUND: Tibial shaft fracture is the most common type of long bone fractures, and intramedullary nailing is the treatment of choice. Anterior knee pain (AKP is the most common complication of tibial nailing. The exact etiology of AKP is unknown, and the reported incidence is between 10-86%. Since many activities of daily living of Iranians need kneeling, squatting, and tailor position, knee pain can effectively limit these activities. We decided to evaluate knee pain in patients with tibial shaft fractures treated with unreamed intramedullary nailing in our hospital.
    • METHODS: We evaluated 232 patients between 16-77 year-old with tibial shaft fractures treated with intramedullary nailing from 2005 to 2007 with six months follow up period.
    • RESULTS: According to visual analogue scale (0-10, 165 (71.1% patients had no pain. Anterior knee pain was mild in 54 (28.9% cases; 12 (5.2% cases had moderate pain, and one patient (0.4% experienced severe pain. The most severe pain was felt in kneeling position and the mildest pain was felt in resting position.
    • CONCLUSIONS: The incidence of moderate to severe AKP in patients who had intramedullary nailing for tibial shaft fractures was relatively low. In view of medicolegal litigation, patients should be aware of this complication.

    Nail salons are an important business and employment sector for recent immigrants offering popular services to a diverse range of customers across the United States. However, due to the nature of nail products and services, salon air can be burdened with a mix of low levels of hazardous airborne contaminants. Surveys of nail technicians have commonly found increased work-related symptoms, such as headaches and respiratory irritation that are consistent with indoor air quality problems. In an effort to improve indoor air quality in nail salons, the state of New York recently promulgated regulations to require increased outdoor air and "source capture" of contaminants. Existing indoor air quality in New York State salons is unknown. In advance of the full implementation of the rules by 2021, we sought to establish reliable and usable baseline indoor air quality metrics to determine the feasibility and effectiveness of the requirement. In this pilot study, we measured total volatile organic compounds (TVOC) and carbon dioxide (CO 2 ) concentrations in ten nail salons located in New York City to assess temporal and spatial trends. Within salon contaminant variation was generally minimal, indicating a well-mixed room and similar general exposure despite the task being performed. TVOC and CO 2 concentrations were strongly positively correlated (ρ = 0.81; pair quality for the purposes of compliance with the standard. An almost tenfold increase in TVOC concentration was observed when the American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ANSI/ASHRAE) target CO 2 concentration of 850 ppm was exceeded compared to when this target was met.

    Antegrade interlocked humeral nailing for stabilization of humeral fractures was introduced many years ago, and studies on this method in the orthopedic literature have shown mixed results. The purpose of this investigation was to document the clinical outcome and complications associated with the use of an antegrade intramedullary nail (T2, Stryker) for the humeral fractures. Between 2005 and 2008, 52 fractures of the humeral shaft were treated operatively with this intramedullary nail in our department. Eight patients were polytraumatized, and four patients had an open fracture. The mean age of patients was 51.7 years. Forty-eight patients had an adequate duration of clinical follow-up (a mean of 18 months) for analysis. Complications were recorded, and the time to union was measured. Shoulder and elbow functions were assessed using the Constant Score and the Morrey Score, respectively. Forty-six fractures healed, with a mean time to clinical union of 10.3 weeks. Two patients developed pseudarthroses. There were four adverse events: two proximal screws backed out, one superficial infection at the insertion point, and one fracture at the distal end of the nail. Ninety-one percentage of patients had an excellent or good shoulder function. Five further operations were necessary: two for treatment of pseudarthroses, two for removal the backed out proximal screws, and one wound debridement for superficial infection. Antegrade humeral nailing is a valid therapeutic option for stabilization of humeral shaft fractures. By strictly adhering to the operation technique, the number and the severity of complications can be reduced. When good fracture alignment and stability are obtained, uneventful bone healing with good functional results is the rule.

    Full Text Available Background & Objectives: Although various treatment options are available for the treatment of femoral diaphyesal fractures in children, the titanium flexible nailing has gained popularity because it is safe, easy procedure with rapid recovery and high success rate. The aim of this study was to evaluate the outcome of titanium elastic nails in treating paediatric femoral diaphyesal fractures at Patan Hospital.Materials & Methods: There were 35 cases which were all fixed with titanium flexible intramedullary nail under image intensifier at the Patan hospital from January 2013 and December 2015. Patients were evaluated in follow-ups to observe the alignment of fracture, infection, delayed union, nonunion, limb length discrepancy, implant failure, range of movement of hip and knee joints, and time to unite the fracture. The final results were evaluated using criteria of titanium elastic nail (TEN outcome score described by Flynn et al.Results: The mean age of the patients was 8.51 years. Among 35 patients (22 boys and 13 girls, there were 19 mid-shaft fractures, nine proximal third fractures and seven distal third fractures. Fracture patterns were transverse (22, oblique (10, spiral (2, and comminuted (2. The mean time for fracture union was 8.17 weeks radiologically whereas 9.83 weeks clinically. According to TEN outcome score, excellent and good results were in 28 cases (80% and seven cases (20% respectively.Conclusion: Flexible titanium nailing is a safe and satisfactory treatment for diaphyseal femoral fractures in children, because it provides rapid recovery, short rehabilitation and immobilization as well as very high union rate with few complications.

    Interlocking nails coated with antibiotic-supplemented cement provide effective treatment of infected long bone nonunion, but the thicker coating on guidewires may provide greater antibacterial activity. This study compared the properties of cement cured on each construct by evaluating 2-cm segments of 8-mm interlocking nails and 3.5-mm guidewires coated with antibiotic-supplemented cement. Each construct (n=7 for each group) was coated with polymethylmethacrylate cement (Simplex; Stryker Orthopaedics, Mahwah, New Jersey) containing either 1 g tobramycin or 1 g vancomycin powder plus 2.2 g tobramycin powder. A No. 40 French polyvinyl chloride chest tube was used as a mold for all constructs. Segments were soaked in sterile phosphate-buffered saline, and entire aliquots were exchanged at various intervals over a 6-week period. Antibiotic concentration, antibacterial activity, cement curing temperature, and porosity were measured. At least half of the total elution of antibiotics occurred within the first 24 hours for all constructs. For the tobramycin-only cement, no differences between constructs were observed. For constructs containing both antibiotics, interlocking nails showed more antibiotic release than guidewires at most time points (PAntibiotics were released for 6 weeks and continued to inhibit Staphylococcus aureus growth. Cement curing temperatures for interlocking nails were lower than those for guidewires (Pantibiotic released did not directly relate to porosity for any construct type. Interlocking nails coated with antibiotic-supplemented cement may provide greater antibiotic delivery to infected long bone nonunion compared with guidewires. A thin mantle of cement may allow greater elution, possibly as a result of cooler exothermic reactions. [Orthopedics. 2017; 40(3):e436-e442.]. Copyright 2017, SLACK Incorporated.

    Drug treatment of diseases of the human nail remains a difficult challenge; topical therapy, in particular, is limited by very poor transport of active agents across the nail itself. The objective of this research was to examine the potential of controlled, and fibre-optic delivered, femtosecond laser light pulses to provide new pathways and opportunities for drug access to targets within and beneath the nail plate. Optical, confocal fluorescence and scanning electron microscopies demonstrated partial and complete laser poration of human nail samples, with the energy per pore and the exposure duration being the key modulating parameters that determined the extent of ablation achieved. Parallel measurements of the penetration of a model drug across laser-treated nails showed that complete poration resulted in essentially complete circumvention of the diffusion barrier, an array of 100 pores in 0.2cm 2 area of nail permitting a 10 3 -fold increase in initial drug uptake. Partial ablation of the nail created pores that extended to a range of depths; the nail material adjacent to the ablated area was rendered porous in appearance presumably due to local thermal perturbation of the nail structure. These openings offer, as a result, potential sites in which topical drug formulations might be sequestered post-poration and from which slow, sustained delivery of the active agent into and through the nail may be envisaged.

    Human nail samples have been analyzed to evaluate occupational exposure, nutritional status and to diagnose certain diseases. However, sampling and washing protocols for nail analyses vary from study to study not allowing comparisons between studies. One of the difficulties in analyzing nail samples is to eliminate only surface contamination without removing elements of interest in this tissue. In the present study, a protocol was defined in order to obtain reliable results of element concentrations in human nail clippings. Nail clippings collected from all 10 fingers or toes were previously pre cleaned using an ethyl alcohol solution to eliminate microbes. Then, the clippings were cut in small pieces and submitted to different reagents for washing by shaking. Neutron activation analysis (NAA) was applied for nail samples analysis which consisted of irradiating aliquots of samples together with synthetic elemental standards in the IEA-R1 nuclear research reactor followed by gamma ray spectrometry. Comparisons made between the results obtained for nails submitted to different reagents for cleaning indicated that the procedure using acetone and Triton X100 solution is more effective than that of nitric acid solution. Analyses in triplicates of a nail sample indicated results with relative standard deviations lower than 15% for most of elements, showing the homogeneity of the prepared sample. Qualitative analyses of different nail polishes showed that the presence of elements determined in the present study is negligible in these products. Quality control of the analytical results indicated that the applied NAA procedure is adequate for human nail analysis. (author)

    Nail salon workers are exposed to a variety of toxic chemicals at levels that remain unreported and have undetermined health consequences. The objective of the study was to gather information about the hazards in nail salons along with safety practices and health concerns of nail salon workers. A survey was conducted on 65 nail salon workers who were immigrants from Southeast Asia in Oregon, USA. More than 20% of the participants reported nose irritation and allergies as the most common health problems. Rare and no use of gloves and mask were reported among 72% and 32% of the participants, respectively. A significantly higher number of participants with "fair" or "poor" self-reported general health condition was found among the workers who applied acrylic nails compared with those who were not involved in this application. Findings of the study emphasize the need for more research to determine the relationship between chemical exposures in nail salons and health outcomes.

    Full Text Available Low-energy penetrating nail injury to the brain is an extremely rare neurosurgical emergency. The most common cause of nail gun injury is work related accidents; other causes result from accidental firing of a nail gun, suicide attempts by firing nail guns into the brain, and bomb blasts containing pieces of nails. Neurosurgical treatment performed by craniotomy still seems to be the safest one; there are reports of complications such as subdural hematoma and intraparenchymal hemorrhages following the blind removal of foreign bodies leading to suggestions that all penetrating foreign bodies should be removed under direct vision. We report a rarely described neurosurgical approach for removal of a penetrating nail from the brain and skull without evidence of associated hematoma and other brain lesions.

    Habit tic nail deformity is a nail dystrophy resulting from habitual, repetitive trauma to the nail. It is usually acquired in adulthood, however, we report a case of habit tic nail deformity in an 8 year old boy. The diagnosis was made clinically with further history revealing that the boy repeatedly rubbed his thumbnails and pushed the cuticles. Emollient cream (Balneum®) was recommended twice daily and both the patient and his mother were educated on the behavioral nature of this condition. There was marked improvement at 6 months of treatment and further improvement at 12 months.We note that habit tic nail deformity is not exclusive to adults. Diagnosis can be made clinically. History and physical examination provide valuable clues and psychosocial links must be explored and addressed. Management is challenging and compliance with treatment is variable. Patient education, barrier methods, and behavioral therapy can be helpful in preventing further trauma to the nails.

    Intramedullary nailing of thirty acute displaced open fractures of the tibia and fibula resulted in union with only one superficial infection. The low incidence of sepsis is attributed to the use of the curved malleable Hodgkinson tibial nail which requires no reaming, renders the operation less difficult and traumatic, and interferes minimally with bone vascularity. Fibular nailing was an effective means of stabilizing nine of the twelve fractures close to the ankle joint.

    Conclusions: In Indian patients with nail psoriasis, severity of nail involvement was found to be poorly correlated with the extent of cutaneous disease. In addition the impact of nail disease on patient's quality of life was found to be minimal. This suggests the need for a quality of life questionnaire suited to the Indian population. Serological markers were raised overall in the study patients and more so in the patients with concomitant arthritis.

    Interlocked intramedullary nailing is an accepted technique in the management of closed femoral shaft fractures. If this technique is used in patients who are skeletally immature, the position of locking screws relative to soft tissues can alter with time. We present a case of an 11-year-old male who developed a delayed pseudoaneurysm 4 years after intramedullary nailing that was most likely produced by movement of the distal locking screws of his femoral nail in relation to the surrounding vascular structures.

    The yellow nail syndrome is a clinical syndrome without specific biological parameters. It is characterized by the following threesome of symptoms: nail abnormalities, primary lymphedema, and pleuropulmonary manifestations. In most cases lymphography shows abnormalities of the lymphatic vessels and spirometry shows a restrictive defect and rarely obstructive disorders. Pathogenesis of this syndrome is still unknown. It is, however, remarkable that the yellow nail syndrome may occur in association with other diseases, the most frequent of which are cancer affections and immune disorders. We report two cases of the yellow nail syndrome which were associated with cancer (neoplasm of the larynx and breast).

    Full Text Available Objective:This is a parallel, three group, randomized, controlled clinical trial, with outcomes evaluated up to three months after randomization for children and adolescents with chronic nail biting. The current study investigates the efficacy of habit reversal training (HRT and compares its effect with object manipulation training (OMT considering the limitations of the current literature .Method:Ninety one children and adolescents with nail biting were randomly allocated to one of the three groups. The three groups were HRT (n=30, OMT (n=30, and wait-list or control group (n=31. The mean length of nail was considered as the main outcome .Results:The mean length of the nails after one month in HRT and OMT groups increased compared to the waiting list group (P<0.001, P<0.001, respectively. In long term, both OMT and HRT increased the mean length of nails (P<0.01, but HRT was more effective than OMT (P<0.021. The parent-reported frequency of nail biting did show similar results as to the mean length of nails assessment in long term. The number of children who completely stopped nail biting in HRT and OMT groups during three months was 8 and 7, respectively. This number was zero during one month for the wait-list group .Conclusion:This trial showed that HRT is more effective than wait-list and OMT in increasing the mean length of nails of children and adolescents in long terms.

  4. Locked intramedullary nailing in the treatment of femoral shaft fractures.

    2000-03-30

    In treatment of femoral shaft fractures the most effective method should be chosen, one which makes rapid bone union possible and facilitates early and efficient rehabilitation. In our opinion locking intramedullary nailing fulfils these requirements. This is a technically demanding procedure that requires considerable experience on the part of the operating team. A knowledge of the physiology of fracture healing would appear to be the key to obtaining a good treatment outcome. Closed intramedullary nailing is a less invasive method of osteosynthesis because it does not require the fracture site to be opened. Familiarity with the various operative stages and good teamwork reduce operating time and X-ray exposure, and insure the best treatment outcome.

We report the first case of ESFA of the nail apparatus, which presented as a yellow longitudinal onycholytic band of the left fourth finger over an intermittently painful subungual filamentous tumour. Histological examination showed features of ESFA with a digitate pattern of papillomatosis due to the specialized physiological longitudinal arrangement of the ridges in the nail bed. In addition, we describe a new feature of colloidal iron-positive clear cells. In our case, the presence of two types of cells with a central ductal differentiation and a significant amount of mucopolysaccharides in clear cells could suggest differentiation towards both the ductal and the secretory portion of the eccrine gland.

    Voriconazole was 1 of 2 antifungal agents recommended for treatment of fungal infections associated with injection of contaminated methylprednisolone. Alopecia and nail changes are not commonly reported side effects of voriconazole. Having noted increasing hair loss among our patients treated with voriconazole, we sought to determine the prevalence and characteristics of alopecia associated with this agent. Patients who received voriconazole for at least 1 month for probable or confirmed fungal infection were eligible to complete a survey regarding alopecia and nail changes. For those patients who reported alopecia, additional questions about reversal of hair loss were asked after voriconazole had been stopped for at least 3 months. A total of 152 of 175 eligible patients (87%) completed the survey. One hundred twenty-five (82%) reported alopecia. Hair loss on the scalp was noted in 120 (96%), arms and legs in 52 (42%), and eyebrows and eyelashes in 47 each (38%). Nineteen patients (15%) reported wearing a wig or hat because of extensive hair loss. Alopecia developed a mean (standard deviation) of 75 (54) days after initiation of voriconazole. Of 114 patients who were off voriconazole for at least 3 months, hair loss had stopped in 94 (82%) and regrowth had begun in 79 (69%), including those who were changed to either itraconazole or posaconazole. Nail changes or loss occurred in 106 (70%) patients. Alopecia and nail changes were common adverse effects associated with voriconazole therapy during the multistate fungal outbreak. © The Author 2014.

    Full Text Available Introduction: Papulosquamous drug eruptions are a group of skin lesions, triggered by various drugs. Hepatitis B is an important health problem all over the world as well as in our country. Entecavir is a nucleoside analogue used in the treatment of chronic hepatitis B. Case: A 56-year-old female patient using entecavir for chronic hepatitis B for four years admitted to our outpatient clinics with dystrophic changes on the finger nails and toe nails, and scaling erythematous lesions of fingers and toes for one year. She had no drug history other than entecavir. Laboratory examination revealed: HbsAg: positive, HBeAg: negative, anti-HBe: positive, HBV DNA: negative, total anti-HDV: negative, and alanine aminotransferase: 32 U/L. Biopsies were taken from the patient's finger and toe nails after three negative fungal examination of native smears. Biopsy results were consistent with drug eruptions and according to these results, the lesions were thought to be a side effect of entecavir. Entecavir treatment was terminated and transaminase levels were followed at regular intervals. Mometasone fruat ointment and moisturizer containing urea (2 times a day/seven days were started for the treatment of skin lesions. Two weeks later the lesions were showed improvement and the patient was called to follow up at regular intervals. Conclusion: To our best knowledge there was only one case report in the literature so far, about drug eruptions with entecavir. Here we described the first case who developed papulosquamous skin eruptions and nail disorders due to treatment of entecavir.

    Full Text Available In this section, paraneoplastic entites of hair, nail, oral mucosa and pigmentation changes have been discussed. Some skin findings are “strong” indicator of a malignancy whereas others are not. Readers will encounter some “coincidental” or “common” entities as well as more “severe” changes for a paraneoplastic sign. In addition, it is crucial that some paraneoplastic lesions may predict for a recurrence of malignancy.

    The radiological and clinical features of two families with a nail-patella syndrome are described. Our findings emphasize the varying expressivity of the syndrome, which has an autosomal dominant mode of inheritance and a penetrance of 100%. It is important for the radiologist to be aware of the syndrome's stigmata so that renal failure can be detected as early as possible after the diagnosis of skeletal dysplasia. (orig.) [de

    Three patients had compartment syndrome of the leg after tibial intramedullary nailing with reaming. They were all treated successfully with emergency fasciotomy. A prospective study was done of seven additional patients who had continual monitoring of the pressure in the deep posterior compartment during tibial intramedullary nailing with reaming. In five of them, the procedure was performed three weeks or less after injury and in the remaining two, the nailing was performed later for the treatment of non-union. Two pressure peaks in the deep posterior compartment were noted: one after strong longitudinal traction was applied and the fracture was reduced and the other during intramedullary reaming. Intraoperative pressure of thirty millimeters of mercury or more were recorded in three of the seven patients. In the treatment of tibial fractures, operative procedures that involve forceful traction for a long time may predispose the patient to compartment syndrome in the leg. Close clinical observation of such patients is needed. When there is a high risk of compartment syndrome, monitoring of the pressure in the compartment may be prudent.

    Full Text Available Background: Onychomycosis is one of the most common nail disorders. Mycological examination by potassium hydroxide (KOH mount and fungal culture is the most commonly used diagnostic method. However, it is associated with a low sensitivity. Aims: To evaluate the technique of subungual hyperkeratosis nail biopsy in diagnosing onychomycosis in HIV-infected and immunocompetent adults and compare it with mycological examination. Methods: 34 HIV-positive patients who presented clinically with onychomycosis were recruited in the study from the beginning. There was no screening done for patients with onychomycosis. This has been clarified in manuscript under the heading of methods. Results: All the fungal cultures yielded dermatophytes correlating with the biopsy findings. Only hyphal form of fungus was detected in KOH examination, indicating it was not a contaminant. Clinical types of onychomycosis are stated in discussion. Conclusions: PAS stain of subungual hyperkeratosis nail biopsy was the most sensitive in the diagnosis of onychomycosis in both HIV-infected and non-infected groups.

    Interlocking nails are commonly performed using an image intensifier. These are expensive and are not readily available in most resource-poor countries of the world. The aim of this study was to achieve interlocking nailing without the use of an image intensifier. This is a prospective descriptive analysis of 40 consecutive cases seen with shaft fractures of the humerus, femur, and tibia. Fracture fixation was done using Surgical Implant Generation Network (SIGN) nails. Forty limbs in 34 patients were studied. There were 12 females and 22 males, giving a ratio of 1:2. The mean age (years) was 35.75+/-13.16 and the range was 17-70 years. The studied bones were: humerus 10%, femur 65%, and tibia 25%. The fracture lines were: transverse 40%, oblique 15%, and communited 45%. Fracture grades were: closed 90%, grade I, 5%, grade II, 2.5%, and grade IIIA, 2.5%. Surgical approaches were: antegrade 62.5% and retrograde 37.5%. Indications for fixation were: recent fracture 92.5%, non-union 5%, and malunion 3%. Methods of reductions were: open 85% and closed 15%. The mean follow-up period (years) was 1.50+/-0.78. The union time averaged 3 months. Complication was mainly screw loosening due to severe osteoporoses in one case. It is, therefore, concluded that, with the aid of external jigs and slot finders, interlocking can be achieved without an image intensifier.

    Full Text Available 【Abstract】 Objective: Studies showed elastic stable intramedullary nailing (ESIN of displaced midclavicular fractures has excellent outcomes, as well as high complication rates and specific problems. The aim was to discuss ESIN of midshaft clavicular fractures. Methods: Totally 60 eligible patients (aged 18-63 years were randomized to either ESIN group or non-operative group between January 2007 and May 2008. Clavicular shortening was measured after trauma and osseous consolidation. Radiographic union and complications were assessed. Function analysis including Constant shoulder scores and disabilities of the arm, shoulder and hand (DASH scores were performed after a 15-month follow-up. Results: ESIN led to a signifcantly shorter time to union, especially for simple fractures. In ESIN group, all patients got fracture union, of which 5 cases had medial skin irritation and 1 patient needed revision surgery because of implant failure. In the nonoperative group, there were 3 nonunion cases and 2 symptomatic malunions developed requiring corrective osteotomy. At 15 months after intramedullary stabilization, patients in the ESIN group were more satisfied with the appearance of the shoulder and overall outcome, and they benefited a lot from the great improvement of post-traumatic clavicular shortening. Furthermore, DASH scores were lower and Constant scores were significantly higher in contrast to the non-operative group. Conclusion: ESIN is a safe minimally invasive surgical technique with lower complication rate, faster return to daily activities, excellent cosmetic and better functional results, restoration of clavicular length for treating mid-shaft clavicular fractures, resulting in high overall satisfaction, which can be regard as an alternative to plate fixation or nonoperative treatment of mid-shaft clavicular fractures.

    Nail involvement in psoriasis is common with a lifetime incidence of 80-90%. It may reflect severity of cutaneous involvement and predict joint disease. Yet it remains, poorly studied and evaluated especially in Indian psoriatic patients. The present study was undertaken to evaluate clinical and serological profile of nail involvement in psoriasis and to assess quality of life impairment associated with nail involvement in Indian patients. Consecutive patients with nail psoriasis were assessed for severity of cutaneous disease (psoriasis area severity index score) and nail disease (nail psoriasis severity index score). The impairment in quality of life attributable to nail disease was scored with nail psoriasis quality of life 10 score. All patients were also assessed for joint disease and tested for inflammatory and serological markers as erythrocyte sedimentation rate, C-reactive protein, rheumatoid factor and anti-cyclic citrullinated peptide antibodies. In our cohort of 38 patients with nail psoriasis, 9 had concomitant psoriatic arthritis. The mean psoriasis area severity index was 14.4 ± 9.6 (range = 0.4-34). The most commonly recorded psoriatic nail changes were pitting (97.4%), onycholysis (94.7%) and subungual hyperkeratosis (89.5%). The mean nail psoriasis severity index score was 83.2 ± 40.1 (range = 5-156) and mean nail psoriasis quality of life 10 was 1.1 ± 0.4. Erythrocyte sedimentation rate and C-reactive protein were raised in 22/38 (57.9%) and 15/38 (39.5%) patients, respectively; rheumatoid factor was positive in 5/38 (13.2%) and anti-cyclic citrullinated peptide antibody was raised in 4/38 (10.5%) patients. Small sample size and lack of a control group. In Indian patients with nail psoriasis, severity of nail involvement was found to be poorly correlated with the extent of cutaneous disease. In addition the impact of nail disease on patient's quality of life was found to be minimal. This suggests the need for a quality of life questionnaire

    Full Text Available To evaluate the fingernail changes in patients with end-stage renal failure (ESRF on regular hemodialysis (HD, we reviewed 69 patients (male 25, female 44; age 40 ± 14.8 years who have been on HD at Samtah General Hospital, Gizan, Kingdom of Saudi Arabia for a mean of 4.3 ± 3.06 years. They were free from congenital, systemic or primary skin disorders contributing to nail changes. The patients were also free from ornamental dyes like henna, traumatic injuries or infections in the fingernails. They were also clinically free from features suggestive of the carpal tunnel syndrome or vascular steal syndrome secondary to arteriovenous fistula (AVF created for vascular access. Their nails were examined under bright day light by the authors independently. The findings consistent among all three observers were taken for analysis. Hemoglobin and serum albumin levels were also estimated. We compared these changes according to age, sex, and duration on chronic hemodialysis, AVF, and the levels of serum albumin and hemoglobin. One or more nail changes were observed in 44/69 (64% patients. The commonest abnormality was the so-called "Half-and-half nail changes", which was observed in the finger nails of 18/69 (26% of the study patients (males to female ratio was 2:1. Typically, the half-and-half nails are nails where the distal portion of the nail bed is red, pink or brown, occupies 20-60% of the total nail length and is always sharply demarcated with the proximal portion. The latter has a dull whitish ground glass appearance and when pressure is applied, the distal discoloration does not fade completely. Non-specific nail changes were observed 26/69 (38% patients. The hemoglobin and serum albumin levels were not significantly different of those with ′half-and-half′ nail, non-specific nail changes or no nail changes. We conclude that various fingernail changes are observed in ESRF patients on HD. These nail changes are independent of the age of the

    This biomechanical study was undertaken to examine the effectiveness of setscrew distal locking in a static intramedullary (IM) femoral nail on the stability of fixation of femoral shaft fractures. Fifteen fresh-frozen cadeveric femora were randomly separated into three groups of five bones and transversely sectioned immediately distal to the isthmus. After the insertion of the large-diameter nails, distal locking was obtained by conventional method in the first group. In the second group, set-screw design was used in which two transverse screws penetrated only the lateral cortex of the femur and compressed the nail in the intramedullary canal. No distal locking was used in the third group. All instrumented femurs were mounted on a servohydraulic testing machine and tested in both rotations (20 degrees) and axial compression (amplitude: 1,000 Newton). Loading-versus-displacement data, acquired at a ten-Hertz sampling rate, were calibrated and used to calculate maximum torque, stiffness, and energy capacity to failure. Maximum displacement and axial stiffness also were determined. Mean maximum torque at 10 degrees for each group were 15.3+/-4.8 newton-meters for the interlocking group, 8.5 +/-1.2 newton-meters for the setscrew group, and 3.6+/-2.7 newton-meters for the nonlocked femora. At 20 degrees of rotational displacement, the torque measured 37.4+/-2.6 newton-meters; 15.0+/-4.0 newton-meters; and 5.3+/-3.1 newton-meters, respectively (p 0.05). The setscrew design provided 87 percent of the torsional rigidity of the interlocking group. In the axial compression test, mean maximum shortening was 1.1+/-0.3 millimeters in the interlocking group and 1.4+/-0.6 millimeters in the setscrew group (p > 0.05). The mean stiffness on longitudinal compression provided by the interlocking screws and the setscrews was 918 and 860 newton-meters per millimeter, respectively. The distal setscrew design provides adequate distal fixation of intramedullary nail for patients in the

    Full Text Available Introduction: Intramedullary nailing has been used frequently for the treatment of tibial diaphyseal fractures. Chronic anterior knee pain has been considered the most frequent post-operative complication of this technique. We investigated the relationship between anterior knee pain and position of nail tip in proximal tibia. Methods: 103 patients were selected among patients who underwent interlocking nailing in our institution. Patients with other factors that might cause anterior knee pain were excluded. In all patients intramedullary nailing was done using transpatellar approach. The patients were evaluated in two groups, 42 patients had anterior knee pain (Group A, whereas 61 patients did not have pain (Group B. The distance from nail tip from tibial plateau was measured on lateral radiographs. Nail prominence from anterior tibial cortex was also measured. Results: The two groups were similar with respect to gender and follow up period. Out of 42 patients who had knee pain 21 (50% had nail tip within proximal third distance from plateau to tibial tuberosity. Twenty-four patients (42% among knee pain group had nail prominence of more than 5mm from anterior tibial cortex followed by 12 patients (29% within 5mm and 12 patients (29% nail tip buried within the anterior cortex. Conclusion: A greater incidence of knee pain was found when nail was prominent more than 5mm and when it is in the proximal third distance from tibial plateau to tuberosity. Patients should be aware of high incidence of knee pain when the nail tip is placed in proximal third and prominence of more than 5mm.

    Full Text Available Background. Enteroviral infections are common infections, mostly affect children. Nail changes of enteroviral infection including transverse ridging (Beau's lines and nail shedding (onychomadesis were described in many countries worldwide. Objective. The aim of the research was to investigate the clinical features of the infection that was followed by nail changes during its outbreak in summer-autumn 2016 in Ternopil region, Ukraine. Methods. A case report of 34 children with nail changes that were observed in October 2016 in Ternopil region, Ukraine is presented. All patients were from one kindergarten. Nail trauma, periungual dermatitis, significant medication intake history, systemic diseases were excluded. The survey and clinical examination of cases was performed. Faecal samples were obtained from 13 children with onychomadesis. Results. The median age of the exemined children was 3.97±0.78 years. Interval between onsets of enteroviral infection to nail changes varied from 4 to 12 weeks. Clinical signs that preceded nail changes are fever (64.7%, herpangina (32.6%, pharyngitis (17.6%, gastrointestinal symptoms (44.1%, cutaneous lesions (82.4% as maculopapular, vesicular rash (44.2% or/and skin desquamation (41.2%. These clinical data indicate preceded enterovirus infection. In 21 (61.8% patients hand-foot-mouth disease was suggested. Nail changes were presented by Beau's lines and onychomadesis (nail shedding. The number of affected nails varied from 1 to 16, the median number was 4.88±4.09. Conclusions. Our study proved association between the outbreak of onychomadesis (nail shedding and enteroviral infection, mainly hand-foot-mouth disease, during summer-autumn 2016 in Western Ukraine (Ternopil region. Enteroviral infection was followed by onychomadesis in 4-12 weeks. Clinical features of enteroviral infection were very variable, with prevalence of cutaneous lesions. More studies are necessary to determine the serotype of the virus that

    An estimated 3700 individuals are seen annually in US emergency departments for nail gun-related injuries. Approximately 45 cases have been reported in the literature concerning nail gun injuries penetrating the cranium. These cases pose a challenge for the neurosurgeon because of the uniqueness of each case, the dynamics of high pressure nail gun injuries, and the surgical planning to remove the foreign body without further vascular injury or uncontrolled intracranial hemorrhage. Here we present four cases of penetrating nail gun injuries with variable presentations. Case 1 is of a 33-year-old white man who sustained 10 nail gunshot injuries to his head. Case 2 is of a 51-year-old white man who sustained bi-temporal nail gun injuries to his head. Cases 3 and 4 are of two white men aged 22 years and 49 years with a single nail gun injury to the head. In the context of these individual cases and a review of similar cases in the literature we present surgical approaches and considerations in the management of nail gun injuries to the cranium. Case 1 presented with cranial nerve deficits, Case 2 required intubation for low Glasgow Coma Scale, while Cases 3 and 4 were neurologically intact on presentation. Three patients underwent angiography for assessment of vascular injury and all patients underwent surgical removal of foreign objects using a vice-grip. No neurological deficits were found in these patients on follow-up. Nail gun injuries can present with variable clinical status; mortality and morbidity is low for surgically managed isolated nail gun-related injuries to the head. The current case series describes the surgical use of a vice-grip for a good grip of the nail head and controlled extraction, and these patients appear to have a good postoperative prognosis with minimal neurological deficits postoperatively and on follow-up.

    The management of intramedullary long bone infections remains a challenge. Placement of antibiotic cement nails is a useful adjuvant to the antibiotic treatment of osteomyelitis. However, fabrication of antibiotic cement nails can be arduous. The purpose of this article is to introduce an easy and reproducible technique for the fabrication of antibiotics cement nails. We compared the time required to peel the chest tube off the 6 antibiotic cement nail using 2 different cement-cooling techniques and the addition of mineral oil in the chest tube. Additionally, we evaluated the optimal time to cut the chest tube (before and after cement hardening), consistency of nail's diameter, and the roughness of its surface. Cooling and peeling times were measured and failure was defined as a working time (from cement mixing to have a usable antibiotic cement nail) that exceeded 1 h. When the antibiotic cement nail was left to cool by convection (i.e. air-cooling), we failed to peel the plastic off the cement nail. When the chest tube was cut after conductive cooling (i.e. cold water-cooled), the cooling time was 10 min and the peeling time was 30 min without the use of mineral oil; the addition of mineral oil reduced peeling time to 7.5 min. Following peeling, residual adherent plastic pieces were found along the entire surface of the nail when no mineral oil was used. This was rarely seen when mineral oil was utilized to coat the inner layer of the chest tube. Conductively cooling of the cement nail (in cold water) and pre-lubricating the chest tube with mineral oil are 2 tricks that render fabrication of antibiotic nail more efficient, reliable, and practical.

    In 2004, we modified our technique for the stabilization of femoral shaft fractures so that all fractures were stabilized using a reconstruction nail with proximal locking screws oriented into the femoral head. The rationale for this was twofold: first, potentially "missed" associated femoral neck fractures would be stabilized. Second, hip fractures that might occur later in life above the intramedullary nail might be avoided. The purpose of this study therefore was to determine whether there were any risks to patients treated for femoral shaft fractures with antegrade nails using cephalomedullary proximal locking screws. Retrospective. Two regional trauma centers. Eighty-seven consecutive patients were treated for a femoral shaft fracture treated with antegrade femoral nailing with a cephalomedullary locked nail. Reamed, trochanteric insertion of an intramedullary nail with proximal locking screws placed in a cephalomedullary direction. Patient and injury data, radiographic analyses, and complications of treatment were assessed at a minimum of 12 months. Sixty-one of 87 patients (70%) were available at a mean of 19.8 months (range, 12-44 months). Sixty of 61 fractures united after the index procedure. Complications included one delayed union successfully treated with exchange nailing, one distal locking screw fracture (allowing dynamization and completion of fracture healing), two patients with postoperative deformity that required a derotation procedure, and two drill bits that broke intraoperatively and were retained. There were no major complications at the hip, no migration or failure of proximal locking screws, and no screws required removal. Using a reconstruction nail and cephalomedullary proximal locking screws for antegrade femoral nailing of femoral shaft fractures was not associated with major complications in this series. This modification of standard femoral nailing offers potential advantages, including fixation of any "missed" associated femoral

    Conclusion: Majority of paediatric femoral shaft fractures are now treated operatively by elastic stable intramedullary nails. Operative intervention results in a shorter hospital stay and has economic and social benefits over conservative treatment. The cost of stainless steel nail is one third the cost of titanium nail. However, the clinico-radiological results are not significantly different between titanium and stainless steel nails at one year follow-up as observed by our study.

    The authors describe the Ender's technique in the treatment of fractures of the trochanteric region. They realise a blind nailing, introducing "elastic" nails in the region of the medial condyle, under Xray control. The authors have conducted a biomechanical study comparing this type of nailing with nail-plating (extensometry and mathematical theory). 51 patients were operated-on. The results are analysed. The authors point out that the surgical procedure is very fast and simple, therefore they support it for aged people.

  8. Evaluation of the Drug Treatment and Persistence of Onychomycosis

    Directory of Open Access Journals (Sweden)

    Full Text Available Onychomycosis is a common nail disease responsible for approximately 50% of diseases of the nail. It occurs more in the elderly, though several cases have been reported among children. Several factors influence, such as climate, geography, and migration. The two dermatophytes most commonly implicated in onychomycosis are Trichophyton rubrum and T. mentagrophytes, accounting for more than 90% of onychomycoses. Nonetheless, several other toxigenic molds have been implicated. For convenience, onychomycosis is divided into four major clinical presentations: distal subungal, which is the most common form of the disease; proximal subungal, which is the most common form found in patients with human immunodeficiency virus infection; superficial; and total dystrophic onychomycosis. Epidemiology of onychomycosis in adults and children is evaluated and the most common clinical symptoms addressed. Although the risk factors are discussed, the multifactorial nature of onychomycosis makes this inexhaustible. The diagnosis and treatments are difficult and the choice of appropriate antifungal drugs complex and require the knowledge of the chemical structures of the metabolites of the molds that cause onychomycosis and their interaction with the antifungal drugs. This is true because most of the antifungal drugs are derived from mold/fungal metabolism. Treatment with griseofulvin and amphotericin is displaced by the use of newer drugs from azole compounds, pyrimidines, and allylamines derivatives. Amorolfine, itraconazole, and ciclopirox nail lacquer solution 8 have gained support globally, but the side effects, drug resistance, and persistence of the disease are still a serious concern to the patients, just as economics and quality of life. Hence, the search for safer and more efficacious drug treatments are continuing.

    Full Text Available Paecilomyces lilacinus, a filamentous fungus living saprophytic in the environment, very rarely causes infection in immunocompetent humans, mostly ocular or cutaneous and sub-cutaneous infections.The fungal isolates usually show low susceptibility to conventional antifungal drugs in vitro and variable susceptibility to novel triazoles. During a period of 2 years, 4 cultures of nail fragments were grown from a 41 years old female on modified Sabouraud/Dextrose agar (S.D.A. (CAF bioMérieux, CAF+CEX Biolife. Cultures were continued in suspension and the hyphae stained with lactophenole blue analysed microscopically. 2 samples were tested with molecular methods, i.e. DNA extraction, amplification of internal transcribed spacer (ITS region 1 and 2 and automated sequencing. The sequence results were evaluated using a validated reference database for humanpathogenic fungi. Additionally the BLAST algorithm on NIH database GenBank was used. A growth of a filamentous hyaline fungus with white colonies and lila shade was observed in all samples. The presence of Penicillium like conidiophores with divergent long terminal phialides was seen with little elliptical conidia. DNA sequencing determined the species as Paecilomyces lilacinus with 99% homology with GenBank isolate AY213667. The infection of the right hallux did not improve by systemic (Lamisil/terbinafine and local treatment (Locetar/amorolfin nail lacquer.Also change to Sporanox/itraconazol only led to deterioriation, so finally the extraction of the nail had to be performed given the known difficulties with treatment described in the literature. This case highlights the usefulness of molecular techniques, especially use of the highly discriminative ITS region for fungal typing.

    Flexible intramedullary nails have been indicated to treat femoral fractures in pediatric patients. The purpose of this study was to examine the stability of simulated transverse fractures after retrograde intramedullary flexible nail fixation. Various nail diameter combinations were tested using composite femurs in bending, torsion, and a combined axial/bending test where a vertical compressive force was applied to the femoral head. The cross-sectional percent area fill of the nails within the femurs was also determined. In 4 point bending, the greatest repair stiffness was 12% of the intact stiffness. In torsion, the greatest stiffness was 1% of the intact stiffness for either internal or external rotation. The greatest repair stiffness was 80% of the intact stiffness for a compressive load applied to the femoral head. Nail combinations with single nail diameters greater than 40% of the mid-shaft canal width, as measured from an AP radiograph, prevented the fracture from being reduced and left a posterior gap. Flexible intramedullary nails may be of value in the treatment of pediatric femoral fractures, but care must be taken to insert nails that are correctly sized for the canal and to protect the healing fracture from high torsional and bending loads.

  19. Loss of bone strength after intramedullary nailing. Torsion tests of tibial osteotomies in rabbits.

    Kaartinen, E; Paavolainen, P; Holmström, T; Slätis, P

    1985-12-01

    Rigid intramedullary nailing was used in 75 rabbits to stabilize a transverse osteotomy of the midshaft of the tibia. In 36 additional rabbits intramedullary nailing was performed without osteotomy. No additional external immobilization was used postoperatively. After removal of the nail the mechanical strength of the tibiofibular bones was tested torsiometrically in 30 osteotomized and 18 non-osteotomized animals from 3 to 24 weeks after the operation. At 3 weeks the torsional load fractured all osteotomized bones through the osteotomy line. At later stages a spiral fracture occurred either crossing or close to the osteotomy area, usually distal to the tibiofibular junction. The increase in mechanical strength of the osteotomized bones reached a maximum at 6 weeks and then decreased. The strength of the non-osteotomized nailed bones also decreased slightly. The results suggest that rigid intramedullary nailing, although providing good conditions for early consolidation of experimental osteotomy, leads secondarily to deterioration of the mechanical properties of tubular bone.

  20. The locked flexible intramedullary humerus nail in pediatric femur and tibia shaft fractures: a feasibility study.

    2004-01-01

    There are several options for the treatment of long bone fractures in skeletally immature patients. Surgeon experience, type of fracture, and the possibility of damage to the physeal area dictate individual fracture management patterns. Notably, nail devices have not gained popularity in this patient group. Intramedullary locking nails have become the standard of care in adult patients due to decreased morbidity and mortality. A novel nail has been developed for humeral shaft fractures that uses a lateral starting position to avoid damage to the rotator cuff in humeral fracture fixation. This is possible because of the nail's transient flexibility during insertion. This study illustrates that it is feasible to insert this type of nail through multiple entry portals for both tibial and femoral fracture fixation, without damaging the physeal blood supply or growth areas.

    The purpose of this study was to compare the results between exchange nailing (EN) and augmentation plating (AP) with a nail left in situ for nonisthmal femoral shaft nonunion after femoral nailing. : Retrospective data analysis, November 1996-March 2006. A level I trauma center. Eighteen patients with 18 nonisthmal femoral nonunions. Seven patients with 7 fractures treated for nonisthmal femoral shaft nonunions after femoral nailing with EN and 11 patients with 11 fractures treated for nonisthmal femoral shaft nonunions after nailing with AP combined with bone grafting. Union and complications. Five nonunions in the EN group failed to achieve union (72% failure rate), whereas all 11 pseudarthroses in the AP group obtained osseous union. Fisher exact test showed a higher nonunion rate of EN compared with AP for nonisthmal femoral shaft nonunion (odds ratio, 6.5; P = 0.002). AP with autogenous bone grafting may be a better option than EN for nonisthmal femoral nonunions.

    Anterior knee pain (AKP) is one of the most common complications after tibia intramedullary surgery. We evaluated changes in patellar tendon length after tibia intramedullary nailing surgery using a transtendinous approach and assessed the importance of nail position in relation to the anterior tibial cortex and joint line. Two surgeons blinded to patients' pain status measured both the knee Insall-Salvati and Caton-Deschamps indexes on 30° flexion lateral knee X-rays of 33 patients. Superior nail prominence (the distance from the proximal tip of the nail to the tibial plateau) and anterior nail prominence (the distance from the anterior tip of the nail to the anterior tibial cortex) were measured on the CT. Clinical assessment showed that 10 patients (30 %) had AKP at the last follow-up. HSS and Lysholm scores and the incidence of AKP were similar between patients whose IM nails were removed and those who still had them. HSS score, Insall-Salvati, and Caton-Deschamps indexes were significantly lower in the operated extremity than in the healthy limb at last follow-up. No association was demonstrated between AKP and nail position in relation to the anterior tibial cortex or tibial plateau. According to our study, although the patellar tendon shortened significantly on the affected side compared with the contralateral side, these measurements did not correlate with the presence or absence of pain. AKP and functional knee scores after tibia IM nailing using a transtendinous approach were not associated with nail position in relation to the anterior tibial cortex or tibial plateau.

    2018-03-12

    Objective: To describe the clinical characteristics of respiratory manifestations of yellow nail syndrome. Methods: We conducted a retrospective analysis of 2 patients with respiratory diseases associated with yellow nail syndrome. Their clinical and chest radiological data were collected. We searched PubMed, Wanfang and CNKI databases with the keywords "yellow nail syndrome, yellow nail and lung" in Chinese and English. And the relevant literatures, including 6 articles in Chinese and 81 articles in English, were reviewed. Results: Our 2 patients were male, one 60 years old and the other 76. Typical yellow nails were present in their fingers, and one of them also showed toe yellow nails. One patient was admitted for refractory respiratory infection and he was diagnosed with diffuse bronchiectasis. The respiratory symptoms could be relieved with antibiotics according to the results of sputum microbiological analysis. The other patient was admitted for cough and exertional dyspnea, and refractory pleural effusions were revealed bilaterally. He received repeated effusion drainage by thoracentesis, and Octreotide was tried recently. A total of 373 cases were reviewed in Chinese and English literatures. Pleural effusions (152 cases) and diffuse bronchiectasis (121 cases) were the most common reported respiratory manifestations. Lymphoedema was present in almost all cases with pleural effusion associated with yellow nail syndrome, and the effusion was usually exudative and lymphocyte predominant. Pleurodesis and decortication were effective for them. But, somatostatin analogues had been tried effectively for these patients recently. On the other hand, literatures showed that diffuse bronchiectasis in yellow nail syndrome was less severe than idiopathic diffuse bronchiectasis, and might benefit from long-term macrolide antibiotics. Conclusions: Yellow nail syndrome is a very rare disorder. Besides yellow nail, respiratory manifestations are the main clinical

  4. Study of Ender’s Nailing in Lower Fourth Fractures of Tibia in Adults

    Directory of Open Access Journals (Sweden)

    H. Ladani

    2015-06-01

    Full Text Available ABSTRACT Background: Ender’s nailing in lower fourth tibia fracture preserves periosteal and endosteal blood supply & fracture haematoma, which increases chances of fracture union. There is minimal risk of infection. It provides dynamically controlled motion. Stacking of the canal & splaying of nails provides reasonable axial & rotational stability. Methodology: This is a study of 20 patients of lower fourth extra-articular closed tibial fractures treated with Ender’s nailing. Age was ranging from 20 to 62 yrs. 14 males & 6 female patients were there. Fracture was transverse in 5 patients, short spiral in 5 patients, and oblique in 8 patients & comminuted in 2 patients. Fibula was intact in 5 patients, was fractured at middle or upper third region in 7 patients and at lower third region in 8 patients 3.5 Ender’s nails were used in all patients, four nails in 16 patients& three nails in 4 patients Average surgery time was 50 minutes, average blood loss was 35 cc. No patients had post-operative wound infection. All patients were immobilized for various time periods. Results: Average union time was 16 wks. There were 3 delayed unions. Eventually all fractures united without 2nd surgical intervention. In 5 patients there was significant proximal migration of nails, causing slight knee discomfort. Nails were removed after solid fracture union in those cases. Between 1 & 2 cm shortening was found in two patients more than 50 varus-valgus or antecurvatum-recurvatum deformity was found in two patients, but not having any symptomatic problem. Conclusion: Ender’s nailing is a good alternative in lower fourth tibia fractures. It gives increased chances of fracture union with minimal risk of infection. 2nd surgery of bone grafting or dynamization of I/L nails is not required. The implants are inexpensive & procedure is simple. But a brief period of post-operative immobilization is required.

    The objective of this study is to evaluate the outcome measures of subtrochanteric fractures between biologic plating and intramedullary nailing and determine if biologic plating is superior to intramedullary nailing. Between March 2009 and December 2015, 81 patients with subtrochanteric fractures were enrolled (52 males and 29 females; 31 treated with biologic plating and 50 with intramedullary nailing). Biologic plating was conducted consecutively between May 2011 and March 2013 and intramedullary nailing was performed for the rest of period. Perioperative outcomes including operation time and blood loss during the operation; postoperative radiologic outcomes including union, time to union, coronal alignment, and shortening of the femur; and clinical outcomes including walking ability and pain were evaluated. The biologic plating group was compared with the intramedullary nailing group as a historical control. No significant differences were identified for bony union and time to union between the two different fixation methods Coronal alignment was significantly better in the biologic plating group than in the intramedullary nailing group (pbiologic plating for the treatment of subtrochanteric fractures.

    2006-01-01

    Full Text Available Background: The need for operative fixation of pediatric femoral fractures is increasingly being recognised in the present decade. The conventional traction and casting method for management of pediatric femoral fractures is giving way for the operative stabilisation of the fracture. Methods : Thirty five pediatric patients in age group 6-14 years with diaphyseal femoral fractures were stabilised with two titanium nails. Patients were followed up clinically and radiologically for two years. The final results were evaluated using the criteria of Flynn et al. Technical problems and complications associated with the procedure were also analysed. Results : Overall results observed were excellent in 25, satisfactory in 8 and poor in 2 patients. Hospital time averaged 12.30 days in the series. All the fractures healed with an average time to union of 9.6 (6-14.4 weeks. Return to school was early with an average of 7.8 weeks. The soft tissue discomfort near the knee produced by the nails ends was the most common problem encountered. Shortening was observed in three cases and restriction of knee flexion in 5 patients. There was no delayed union, infection or refractures. Per operative technical problems included failure of closed reduction in 2 cases and cork screwing of nails in one case. Conclusion : We believe that with proper operative technique and aftercare TENs may prove to be an ideal implant for pediatric femoral fracture fixation. The most of the complication associated with the procedure are infact features of inexact technique and can be eliminated by strictly adhering to the basic principles and technical aspects.

    Intramedullary nailing is the gold standard for the treatment of femoral shaft fractures; however, rotational malalignment remains a common complication. The patient can be positioned on the fracture table in a supine position or alternatively in the lateral decubitus position without any traction. The aim of this article is to describe an effective method to control intraoperative torsion of the femur. The surgical technique described in this article is the standard procedure for femoral shaft fractures and subtrochanteric fractures in this level 1 trauma center. The patient is positioned in a lateral position on a radiolucent table with free draping of the injured leg. Using the C-arm, reduction can be performed with this technique with precise placing of the nails and torsion can be exactly adjusted and controlled with the aid of the femoral neck axis, the distal locking holes and both parallel femoral condyles. The described technique represents an effective method for the intraoperative control of femoral torsion. With an acceptable and most probably clinically irrelevant bias, this technique is able to avoid significant rotational malalignment. It does not prolong the operative procedure and does not require additional navigation settings. It has also been shown to be helpful in the treatment of subtrochanteric fractures. The surgical technique of anterograde intramedullary nailing using the lateral decubitus position without any traction device and free draping of the injured leg represents a safe and reliable treatment concept and offers logistical advantages compared to the supine position of the patient on a fracture table. Together with other described methods of intraoperative torsional control of femoral fractures, the radiological technique described in this study is an easily applicable and safe method, which needs to be confirmed in clinical studies.

    2012-06-01

    Functional outcome after retrograde femoral intramedullary nailing was investigated in 35 patients older than 60 years (mean, 86 years) with 36 fractures, comprising 15 (41.7%) shaft and 21 (58.3%) distal fractures; overall, 7 (19.4%) periprosthetic fractures occured. Twenty-two (62.9%) of 35 patients were evaluated at a mean 16.5-month follow-up with the Lyshom-Gillquist score and the SF-8 questionaire. Primary union rate was 97.8%, with no significant differences in duration of surgery, bone healing, mobilization, and weight bearing among different fracture types; periprosthetic fractures revealed a significantly delayed mobilization (P=.03). Complications occured significantly more often among distal femoral fractures (P=.009), including all revision surgeries. The most frequently encountered complication was loosening of distal locking bolts (n=3). Lysholm score results were mainly influenced by age-related entities and revealed fair results in all fractures (mean in the femoral shaft fracture group, 78.1 vs mean in the distal femoral fracture group, 74.9; P=.69), except in the periprosthetic subgroup, which had good results (mean, 84.8; P=.23). This group also had increased physical parameters according to SF-8 score (P=.026). No correlation existed between SF-8 physical parameters and patient age or surgery delay, whereas a negative correlation existed between patient age and SF-8 mental parameters (P=.012). Retrograde femoral intramedullary nailing is commonly used in elderly patients due to reliable bone healing, minimal soft tissue damage, and immediate full weight bearing. It also offers a valid alternative to antegrade nailing in femoral shaft fractures. Copyright 2012, SLACK Incorporated.

    Proximal humeral fractures with a spiral line of fracture extending from the humeral head to the diaphyseal region are increasing. Treatment for these fractures is comparable to that for shaft fractures. The purpose of this study was to evaluate the use of a new "Long" humeral nail for this type of lesion and identify the best distal locking. Forty-three patients treated with a Long Diphos Nail ® were selected for this study: main exclusion criteria were poor cognitive and responsive ability to physical therapy, four-part fracture requiring humeral head replacement, an isolated greater or lesser tubercle fracture and a head-splitting fracture. All patients were divided into two groups according to the distal locking (single or double) and clinically evaluated at 1, 3, 6 and 12 months after surgery. The following parameters were evaluated: fracture healing on radiographic images every month; level of pain with Visual Analogue Scale (VAS); recovery of shoulder function or ability to resume normal daily activities according to the Constant Scoring System (CSS); patient satisfaction; and complications, like fracture consolidation defect or delay. A statistical analysis was performed. Improvements in pain, satisfaction and shoulder functional recovery were recorded. Patients reached fracture healing in two to six months. The mean healing time was better for double distal locking (p=0.04).There was a clinically greater difference (p=0.006) between the groups for the mean Constant score at 3 months follow-up, with better results for the double distal locking group. Complications were: one patient with a consolidation delay with a single distal locking screw breakage; it was necessary to remove the nail and perform a second treatment. The results of the study indicate the efficacy of Long Diphos Nail ® in the treatment of fractures with a line of fracture extending to the proximal diaphyseal region. The features of a multiplane stabilisation above the fracture and a

    Introduction: There are limited information and inconclusive results for dual head screw intramedullary hip nails for trochanteric fractures. Therefore, we performed a prospective study to evaluate the healing of fractures, and survival, function, and complications of patients operated with this implant. Methods: We prospectively studied 79 patients (61 women and 18 men; mean age: 84.7 years; range: 65–96 years) with a low-energy trochanteric fracture, treated with a dual head screw intramedullary hip nail from 2013 to 2016. The mean follow-up was 2.1 years (range: 1–3 years); seven patients were lost to follow up. This left 72 patients for further analysis. We evaluated the healing of fractures, and survival, function, and complications of patients. Results: Fracture healing was evident in 70 patients (97.2%) at 2–3 months postoperatively. One patient experienced cut-out and z-effect phenomenon of the head screws. Another patient experienced a periprosthetic femoral diaphysis fracture at the distal tip of the nail. A third patient experienced an acute postoperative superficial skin infection that was treated successfully with wound dressing changes and a course of antibiotics. Sixteen patients (22.2%) deceased within 12 months postoperatively. In the remaining patients, the Harris Hip Score (HHS) at 12 months postoperatively was excellent in 16 (28.6%), good in 23 (41.1%), fair in 10 (17.8%), and poor in 7 patients (12.5%). The function declined after the patients’ fracture. Fair and poor results were related to age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types. Conclusion: The dual head screw intramedullary hip nail is associated with high healing and low complication rates for intertrochanteric fractures. The function of the patients is good or excellent in most cases; however, it declines, especially for those patients with age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types

One patient experienced cut-out and z-effect phenomenon of the head screws. Another patient experienced a periprosthetic femoral diaphysis fracture at the distal tip of the nail. A third patient experienced an acute postoperative superficial skin infection that was treated successfully with wound dressing changes and a course of antibiotics. Sixteen patients (22.2% deceased within 12 months postoperatively. In the remaining patients, the Harris Hip Score (HHS at 12 months postoperatively was excellent in 16 (28.6%, good in 23 (41.1%, fair in 10 (17.8%, and poor in 7 patients (12.5%. The function declined after the patients’ fracture. Fair and poor results were related to age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types. Conclusion: The dual head screw intramedullary hip nail is associated with high healing and low complication rates for intertrochanteric fractures. The function of the patients is good or excellent in most cases; however, it declines, especially for those patients with age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3

    There has been limited literature indicating that podiatrists' health may be at risk from exposure to human nail dust. Previous studies carried out in the UK have shown that large amounts of dust become airborne during the human nail drilling procedure and are present in the air up to 10 hours after a clinical session. This increases the risk of Respiratory Tract (RT) infection for the practitioner. This study used a nasal swabbing technique and fungal culture to determine whether podiatrists (n = 50) had the same microbes present in their nasal cavities as non-podiatry health professional control group (n = 45). All swabs were cultured, counted and identified for each subject. Survey data of use and type of nail drill, type of mask used and frequency of change over a two week period. The results showed podiatrists had a greater range of microbes in their nasal cavities although the controls had greater overall numbers of organisms. The known pathogen and common mould, Aspergillus fumigatus was ost commonly found fungus within the podiatric group with 44% of the group having the fungus present. All nail drills used by the podiatrists had some form of dust extraction (except one). Of concern was 17% (n = 8) of the podiatrists did not use a mask at all whilst drilling and seemed unaware of any infection control issues. Simple disposable masks were the most frequently worn with only half being changed after each patient further increasing the cross infection risk The high levels of Aspergilus contamination is a significant finding in the podiatry group as this fungus is small enough to enter the tissue of the nasal cavity and as a small particle will stay airborne in the room for up to 16 hours. Aspergilus has been shown to cause brain and soft tissue tumours in extreme cases. The high levels of upper respiratory track problems reported in the literature may well be caused by this fungal agent. The non use and use of inappropriate masks by podiatrists is clearly an

    Full Text Available Based on the back-propagation algorithm of artificial neural networks (ANNs, this paper establishes an intelligent model, which is used to predict the maximum lateral displacement of composite soil-nailed wall. Some parameters, such as soil cohesive strength, soil friction angle, prestress of anchor cable, soil-nail spacing, soil-nail diameter, soil-nail length, and other factors, are considered in the model. Combined with the in situ test data of composite soil-nail wall reinforcement engineering, the network is trained and the errors are analyzed. Thus it is demonstrated that the method is applicable and feasible in predicting lateral displacement of excavation retained by composite soil-nailed wall. Extended calculations are conducted by using the well-trained intelligent forecast model. Through application of orthogonal table test theory, 25 sets of tests are designed to analyze the sensitivity of factors affecting the maximum lateral displacement of composite soil-nailing wall. The results show that the sensitivity of factors affecting the maximum lateral displacement of composite soil nailing wall, in a descending order, are prestress of anchor cable, soil friction angle, soil cohesion strength, soil-nail spacing, soil-nail length, and soil-nail diameter. The results can provide important reference for the same reinforcement engineering.

    There is a considerable interest in the determination of trace elements in human nails in order to use this tissue as a monitor of nutritional and healthy status of individuals, of occupational exposure diseases and of the environmental contamination. In this work, instrumental neutron activation analysis was applied to determine trace elements in finger nail clippings to make comparisons between the elemental concentrations obtained in nails from healthy individuals of a control group and those from cystic fibrosis (CF) patients. Firstly, a protocol for sample collection and preparation for analysis was established. Finger and toe nail samples from CF patients were collected at the Instituto da Crianca of Medicine School, University of Sao Paulo, SP. The nail samples from control group were collected from healthy adults and from children living in Sao Paulo city, SP. These samples were cleaned by stirring them witha a diluted Triton X100 solution and then by washing with distilled water and acetone. The analytical procedure consisted of irradiation nail samples and elemental standards in the IEA-R1m nuclear reactor under thermal neutro flux of about 10 12 n cm -2 s -1 , for short and long period irradiations. The activities of the radionuclides were measured using a gamma-ray spectrometer comprising an hyperpure Ge detector and associated electronic system. The biological reference materials Bovine Liver 1577b and Oyster Tissue 1566a, both from National Institute of Standards and Technology, USA were analysed in order to evaluate the accuracy and precision of the results. The analysis of variance (ANOVA) and F-test at the significance level of 5% were used to make a comparison between the sets of results obtained in this work. In the comparison of the results obtained for finger and toe nails from CF patients, the Br concentrations were higher in finger nails that those obtained for toe nails. For the control group of children, the finger nails presented different

    Onychomycosis describes a chronic fungal infection of the nails most frequently caused by dermatophytes, primarily Trichophyton rubrum. In addition, yeasts (e. g. Candida parapsilosis), more rarely molds (Scopulariopsis brevicaulis), play a role as causative agents of onychomycosis. However, in every case it has to be decided if these yeasts and molds are contaminants, or if they are growing secondarily on pathological altered nails. The point prevalence of onychomycosis in Germany is 12.4%, as demonstrated within the "Foot-Check-Study", which was a part of the European Achilles project. Although, onychomycosis is rarely diagnosed in children and teens, now an increase of fungal nail infections has been observed in childhood. More and more, diabetes mellitus becomes important as significant disposing factor both for tinea pedis and onychomycosis. By implication, the onychomycosis represents an independent and important predictor for development of diabetic foot syndrome and foot ulcer. When considering onychomycosis, a number of infectious and non-infectious nail changes must be excluded. While psoriasis of the nails does not represent a specific risk factor for onychomycosis, yeasts and molds are increasing isolated from patients with psoriatic nail involvement. In most cases this represents secondary growth of fungi on psoriatic nails. Recently, stigmatization and impairment of quality of life due to the onychomycosis has been proven.

    Onycholysis, separation of the nail plate from the nail bed, is etiologically classified as primary (idiopathic) or secondary (eg, caused by psoriasis, squamous cell carcinoma). Repetitive microtrauma plays a role in idiopathic onycholysis and also facilitates human papillomavirus (HPV) infection. Herein, we report a case of persistent primary onycholysis associated with repetitive trauma and infection by a multiplicity of Beta-papillomavirus (Beta-PV) genotypes. An otherwise healthy 27-year-old woman presented with a 6-year history of onycholysis of the halluces and right second toe. Her occupation required wearing steel-toed boots. Fungal cultures were negative and antifungal therapy was ineffective. Punch biopsy of the hallux nail bed revealed epidermal hyperplasia, acanthosis, hypergranulosis, hyperkeratosis, and regions of koilocytosis without significant inflammation. This histopathology implicated chronic irritation and HPV infection. Immunohistochemistry demonstrated productive HPV infection. Nested PCR using degenerate consensus primers revealed infection with 5 known and 1 novel Beta-PV genotypes (HPV 5, HPV 8, HPV 20, HPV 23, HPV 37, and FA25). The histopathology of primary onycholysis is unknown. Based on the aforementioned, we propose that repetitive microtrauma caused by wearing steel-toed boots promoted onycholysis and HPV infection, the latter of which, altered the differentiation of nail bed epithelium, preventing adhesion of nail plate to the nail bed. Lastly, the presence of oncogenic Beta-PV genotypes (ie, HPV 5, 8, and 20) implicates a risk for subungual squamous cell carcinoma, particularly if the nail remains symptomatic and persistently irritated.

  18. Hydration of nail plate: a novel screening model for transungual drug permeation enhancers.

    Chouhan, P; Saini, T R

    2012-10-15

    Drug delivery by topical route for the treatment of onychomycosis, a nail fungal infection, is challenging due to the unique barrier properties of the nail plate which imparts high resistance to the passage of antifungal drugs. Permeation enhancers are used in transungual formulations to improve the drug flux across the nail plate. Selection of the effective permeation enhancer among the available large pool of permeation enhancers is a difficult task. Screening the large number of permeation enhancers using conventional Franz diffusion cells is laborious and expensive. The objective of present study was to evolve a simple, accurate and rapid method for screening of transungual drug permeation enhancers based on the principle of hydration of nail plate. The permeation enhancer which affects the structural or physicochemical properties of nail plate would also affect their hydration capacity. Two screening procedures namely primary and secondary screenings were evolved wherein hydration and uptake of ciclopirox olamine by nail plates were measured. Hydration enhancement factor, HEF(24) and drug uptake enhancement factor, UEF(24) were determined for screening of 23 typical permeation enhancers. The Pearson's correlation coefficient between HEF(24) and UEF(24) was determined. A good agreement between the HEF(24) and UEF(24) data proved the validity of the proposed nail plate hydration model as a screening technique for permeation enhancers. Copyright © 2012 Elsevier B.V.

    An effective topical antifungal medication must penetrate through the nail plate at sufficient concentrations to eradicate the fungal infection. Tavaborole topical solution, 5% is a novel boron-based pharmaceutical approved for the treatment of toenail onychomycosis due to Trichophyton rubrum or T mentagrophytes. Four in vitro studies assessed the antifungal activity and nail penetration of tavaborole. In Study 1, tavaborole demonstrated minimum inhibitory concentration (MIC) values ranging from 0.25-2 μg/mL against all fungi tested; addition of 5% keratin powder did not affect the MIC against T rubrum. The minimum fungicidal concentration (MFC) values for tavaborole against T rubrum and T mentagrophytes were 8 and 16 μg/mL, respectively. In Study 2, tavaborole effectively penetrated through the nail plate; mean concentrations in the ventral/intermediate nail layer were significantly higher than ciclopirox at day 15. In Study 3, mean cumulative tavaborole penetration through ex vivo human nails was significantly higher than ciclopirox at day 15. In Study 4, tavaborole demonstrated superior nail penetration and fungicidal activity, as measured by zones of inhibition. These studies demonstrated the superior penetration of tavaborole through the nail plate vs ciclopirox. Tavaborole demonstrated robust antifungal activity, with low MIC and MFC values, even in the presence of keratin.

    Tibial intramedullary nailing remains a common tibial fracture fixation method. Tibial nailing indications continue to expand. Neurovascular complications from tibial nailing have been described; however, the proximity of distal tibial locking bolts to the anterior tibial artery (ATA) variants has not. 52 cadaveric legs were dissected identifying three common ATA variants. Each ATA variant received an intraluminal wire to facilitate fluoroscopic identification. Three different intramedullary tibial nails were inserted in each of the three ATA variant specimens. With fluoroscopy, the proximity of the distal locking holes of each tibial nail to the intraluminal wire representing the ATA variant course was measured. Of the 40 measurements, the intraluminal wire was directly in the bolt insertional path in 8 of 40 (20%) and within 5 mm in 16 of 40 (40%). All specimens had the wire cross the locking bolt insertional path at least once in each of the nails. The ATA variant taking a more lateral course deep to the extensor digitorum longus and peroneus tertius to overlay the lateral malleolus had the highest occurrence of measurements less than 5 mm. The close proximity of tibial nail distal locking bolt holes to ATA variants presents a risk for iatrogenic vascular injury during insertion. The coronal locking bolts pose the greatest iatrogenic risk to the most laterally positioned ATA variant.

    Soil nailing is one of the recent in situ techniques used for soil improvement and in stabilizing slopes. The process of soil nailing consists of reinforcing the natural ground with relatively small steel bars or metal rods, grouted in the pre-drilled holes. This method has a wide range of applications for stabilizing deep excavations and steep slopes. Soil nailing has recently become a very common method of slope stabilisation especially where situated beneath or adjacent to historical buildings. Stabilisation by nails drilled into existing masonry structures such as failing retaining walls abutments, provide long term stability without demolition and rebuilding costs. Two cases of soil nailing technology aimed at stabilising slopes beneath old buildings in Poland are presented in this paper. The first concerns application of this technology to repair a retaining wall supporting the base of the dam at the historic hydroelectric power plant in Rutki. The second regards a concept of improving the slope of the Castle Hill in Sandomierz. An analysis of the slope stability for the latter case, using stabilisation technique with the piling system and soil nailing was performed. Some advantages of soil nailing especially for protection of historical buildings, are also underlined. And, the main results of an economic comparison analysis are additionally presented.

    The aim of this study was to identify risk factors for failure of exchange nailing for femoral diaphyseal fracture non-unions. The study cohort comprised 40 patients with femoral diaphyseal non-unions treated by exchange nailing, of which six were open injuries. The median time to exchange nailing from primary fixation was 8.4 months. The main outcome measures were union, number of secondary fixation procedures required to achieve union and time to union. Multiple causes for non-union were found in 16 (40%) cases, with infection present in 12 (30.0%) patients. Further surgical procedures were required in nine (22.5%) cases, one of whom (2.5%) required the use of another fixation modality to achieve union. Union was ultimately achieved with exchange nailing in 34/37 (91.9%) patients. The median time to union after the exchange nailing was 9.4 months. Cigarette smoking and infection were risk factors for failure of exchange nailing. Multivariate analysis found infection to be the strongest predictor of exchange failure (punion. However, 50% of patients undergoing exchange nailing in the presence of infection required at least one further procedure. It is important to counsel patients of this so that they can plan for it and do not consider that the first exchange operation has failed. Copyright © 2015 Elsevier Ltd. All rights reserved.

  3. Breakage of a Third Generation Gamma Nail: A Case Report and Review of the Literature

    Full Text Available The use of intramedullary nails to treat trochanteric fractures of the femur has increased with the increasing size of the elderly population. The third generation Gamma nail is currently one of the most popular devices for the treatment of trochanteric fractures. Nail breakage is a rare complication, possibly resulting from fatigue fracture of the implant. We present the first reported case of breakage of a third generation Gamma nail that was not used to treat a pathological fracture. An 83-year-old woman with an unstable trochanteric fracture of the femur was treated using a third generation Gamma nail. She was referred to our hospital 14 months postoperatively with nail breakage at the opening for the lag screw. The breakage was secondary to nonunion, which was thought to be mainly due to insufficient reduction of the fracture. The broken nail was removed, and the patient underwent cemented bipolar hemiarthroplasty. At followup 18 months later, she was mobile with a walker and asymptomatic with no complications. This case shows that inadequate operation such as insufficient reduction of the trochanteric fracture may result in nonunion and implant breakage, even when using a high-strength, well-designed implant.

    Intramedullary nailing has become a standard treatment for adult tibial shaft fractures. Retained intramedullary nails have been associated with stress shielding, although their long-term effect on decreasing tibial bone mineral density is currently unclear. The purpose of this study was to determine if retained tibial intramedullary nails decrease tibial mineral density in patients with successfully treated fractures. Patients treated with statically locked intramedullary nails for isolated, unilateral tibia shaft fractures were studied. Inclusion required that fracture had healed radiographically and that the patient returned to the pre-injury activity level. Data on patient demographic, fracture type, surgical technique, implant, and post-operative functional status were tabulated. Dual energy X-ray absorptiometry was used to measure bone mineral density in selected regions of the affected tibia and the contralateral intact tibia. Image reconstruction software was employed to ensure symmetry of the studied regions. Twenty patients (mean age 43; range 22-77 years) were studied at a mean of 29 months (range 5-60 months) following intramedullary nailing. There was statistically significant reduction of mean bone mineral density in tibiae with retained intramedullary nails (1.02 g/cm(2) versus 1.06 g/cm(2); P=0.04). A significantly greater decrease in bone mineral density was detected in the reamed versus non-reamed tibiae (-7% versus +6%, respectively; Pnails. Intramedullary reaming appears to be a factor potentiating the reduction of tibia bone mineral density in long-term nail retention.

    We reviewed seven patients with established non-union of a shaft of humerus fracture, treated by locked intramedullary nailing using the Intramedullary Supracondylar Nail (IMSC Nail; Smith & Nephew Richards, Memphis TN). The mean age of the patients was 65 years (range 48-78 years). Three of the fractures involved the proximal third of the diaphysis while the remaining four involved the middle third. Six of the original fractures were closed and one was an open fracture. The time interval between the original injury and final surgery averaged 9.3 months. All the nailings were done by the ante-grade approach with static locking. Six of the patients had closed nailing and one had open nailing with bone grafting. The mean follow-up was 8 months and osseous union was achieved in all seven cases at a mean of 5.6 months. We conclude that the Supracondylar Femoral Nail is a useful alternative implant in the management of non-union of fractures of the humeral shaft with wide medullary canals.

    To determine the effectiveness of exchange reamed nails for treatment of aseptic femoral delayed unions and nonunions. Retrospective chart review. Nineteen patients admitted to the Carolinas Medical Center Level I trauma center from 1990 to 1996 for repair of femoral shaft fracture nonunion following contemporary locked nailing performed at least six months previously. These patients showed no radiographic evidence of progression of fracture healing for three months and had clinical symptoms of nonunion. Exchange reamed nails to treat ununited femoral shaft fracture. Radiographic and clinical evidence of union of the fracture or of the necessity for additional procedures. In 53 percent of the patients the secondary procedure resulted in fracture union, whereas in 47 percent, one or more additional procedures were required. Eight of the nine fractures that did not unite with exchange nailing united after a subsequent procedure (bone grafting, compression plating, or nail dynamization). Neither the type of nonunion, the location of the shaft fracture, the use of static versus dynamic cross-locking, nor the use of tobacco products was statistically predictive of the need for additional procedures. Reevaluation of routine exchange nailing as the recommended treatment for aseptic femoral delayed union or nonunion may be required. A significant number of patients who undergo reamed exchange nailing will require additional procedures to achieve fracture healing.

    The results of treatment of fractures of the femoral shaft with static interlocking nailing were reviewed retrospectively to determine the clinical importance of any stress-riser or stress-shielding properties of the nail. These properties, if relevant, would have been manifested by refracture of the femur, either through a hole used for a locking screw or through the original site of fracture after extraction of the device. Two hundred and fourteen fractures that had been treated with static interlocking nailing and that had healed without conversion to dynamic intramedullary fixation were divided into two groups. In Group I, which comprised 111 fractures, the static interlocking-fixation device was retained and in Group II, which comprised 103 fractures, the static interlocking-fixation device was removed during one operative procedure at an average of fourteen months after the injury. The average duration of follow-up was thirty months from the time of the original fixation in both groups. All patients in Group II were followed for a minimum of six months after removal of the nail. No femur in Group I, in which the static interlocked nail remained in situ, refractured. No femur in either group fractured through the proximal or the distal holes used for the locking screws. No locking screws or nails broke. One patient (1 per cent) in Group II had a refracture of the femoral shaft through the site of the original fracture six weeks after removal of the nail.(ABSTRACT TRUNCATED AT 250 WORDS)

    1986-07-01

    We treated 112 fractures of the tibia by manipulative reduction, reaming of the medullary canal, and fixation of the fracture fragments with an intramedullary nail. Seventy-six of the fractures were acute, and eight of these were second or third-degree open fractures. The other thirty-six fractures had a non-union, osteotomy for malunion, or failure of other types of treatment. Follow-up of 100 fractures showed union in all but one, which was in a drug abuser who had an amputation due to infection. The main complication was infection, which was successfully treated in six of seven fractures. The method of treatment, employing either closed or open technique and recently making use of interlocking bolts to stabilize one or both principal fracture fragments on the nail, is an excellent one for unstable acute fractures and for secondary procedures in fractures that are not associated with infection. The infection rate was increased with the open surgical technique. The few contraindications to its use are described.

    Although success of digital replantations in children has been reported by many authors, the very distal fingertip replantation remains technically demanding. The aim of this article is to review our experience with fingertip replantations at or distal to the nail base in pediatric patients and evaluate the clinical outcomes. From October 2000 to May 2007, 12 pediatric fingertips amputated at or distal to the nail base were replanted. Only one artery was anastomosed for revascularization with or without nerve repair; vein drainage was provided by the controlled bleeding technique. Eleven of the 12 replants (91%) survived; one replant of crushed digit failed. An average of 26 month (range, 6 to 36 months) follow-up revealed excellent restoration of finger motion and appearance. The regained static 2-point discrimination (S2PD) sensation was from 3.2 to 5.0 mm (mean, 4.2 mm). Both the parents and the children were satisfied with the final results. In conclusion, fingertip replantation in children allows good functional and esthetical recovery and should be attempted if technically feasible. (c) 2010 Wiley-Liss, Inc.

    Full Text Available A retrospective study on 2 years and 4 months (April 2012 - August 2014 on 430 patients admitted with trochanteric fractures in our Clinic. The surgical indications depended on the patients age, degree of osteoporosis, level activity, associated pathologies and the anatomo-clinical particularity of the fractures. The fractures were operated with gamma nail. The surgery was done in the first 24-72 hours, patients were followed clinically and radiographically at 2, 4, 6 months postoperative. The age of the patients were between 28-95 years, female sex was predominant in 65% of case. It was reported a case of a fracture produced intraoperatory during progression of the nail, 11 bronhopulmonary complications, 5 phlebitis, 7 cases of hematoma after surgery, a case of pseudarthrosis with loosening of implant and 4 dead. There were no septic complications. Fractures consolidate within 12- 14 weeks. The results were appreciated according to fracture reduction, stability of implant, consolidation time and possibility of walking and weight bearing on operated limb.

    2011-05-01

    Laser-induced breakdown spectroscopy (LIBS) is applied to analyze human fingernails using nanosecond laser pulses. Measurements on 45 nail samples are carried out and 14 key species are identified. The elements detected with the present system are: Al, C, Ca, Fe, H, K, Mg, N, Na, O, Si, Sr, Ti as well as CN molecule. Sixty three emission lines have been identified in the spectrum that are dominated by calcium lines. A discriminant function analysis is used to discriminate among different genders and age groups. This analysis demonstrates efficient discrimination among these groups. The mean concentration of each element is compared between different groups. Correlation between concentrations of elements in fingernails is calculated. A strong correlation is found between sodium and potassium while calcium and magnesium levels are inversely correlated. A case report on high levels of sodium and potassium in patients with hyperthyroidism is presented. It is shown that LIBS could be a promising technique for the analysis of nails and therefore identification of health problems.

    Full Text Available INTRODUCTION: Fractures shaft femur is a major cause of morbidity and mortality in patients with lower extremity injuries. The objective of this study was to find out the outcome of Interlocking nail in fracture femur. METHODS: This study was conducted in the Department of Orthopaedic surgery in M. M. Medical College from July 2006 to November 2008. Seventy eight patients were recruited from Emergency and out patient department having closed fracture of femoral shaft. All patients were operated under general or spinal anesthesia. All patients were followed for nine months. RESULTS: Out of seventy eight patients, sixty nine patients underwent union in 90 to 150 days with a mean of 110.68 days. Touch down weight bearing was started on 2nd post-operative day. Complications found in four patients who had non-union, and five patients had delayed union which was treated with dynamization and bone graft. The results were excellent in 88.46% and good in 6.41% patients. CONCLUSIONS: We concluded that this technique is advantageous because of early mobilization (early weight bearing, less complication with good results and is economical.

    The records of fifty-one patients who were treated by intramedullary nailing with reaming for non-union of the tibia were retrospectively reviewed. The fractures had been treated initially by closed reduction and immobilization in a cast, external fixation followed by immobilization in a cast, fixation by pins incorporated in a plaster cast, minimum internal fixation and immobilization in a cast, dynamic compression plating, or intramedullary nailing with or without reaming. After the initial treatment had failed, intramedullary nailing with reaming was done to gain union. Although closed nailing of the tibia was preferred, in thirty-three patients, the site of the non-union was opened to improve alignment by performing an osteotomy or to remove failed hardware. Bone grafts from the iliac crest were used in ten patients, and a fibular ostectomy or osteotomy was done in thirty-three. Of thirty-four open fractures (fourteen grade I, seven grade II, and thirteen grade III), eight were infected at the time of intramedullary nailing. The average time of the diagnosis of a non-union was 9.6 months; the average length of follow-up after nailing was twenty months. In forty-nine (96 per cent) of the fifty-one patients, tibial union occurred at an average of seven months postoperatively. Complications included persistent infection (three patients), acquired infection after intramedullary nailing with reaming (three patients), fracture of the nail that necessitated an additional operation (two patients), shortening of more than one centimeter (two patients), malrotation of more than 15 degrees (one patient), peroneal palsy (one patient), and amputation (one patient). When used to treat non-union of the tibia, intramedullary nailing with reaming can produce union as effectively as other alternatives, while enabling the patient to function more normally without external immobilization or walking aids.

    Successful venous anastomosis is one of the most important factors in fingertip replantation. Volar veins in the fingertip course proximally in a random pattern, which makes it difficult to find out the exact locations. Although dorsal veins in the lateral nail fold have constant location and adequate diameter for anastomosis, they have been known as hard to dissect from the immobile subcutaneous tissue. The authors present a new lateral nail fold incision technique for venous anastomosis in the fingertip amputations. From February 2010 to October 2010, 9 replantations using the new incision and venous anastomosis technique were performed in 9 patients. The levels of amputations were from the nail base to half of the nail bed. After repairing the proper digital arteries, a skin incision was made along the junction between the lateral nail fold and nail bed. Careful dissection was performed to isolate the veins in the lateral nail fold. After evaluation of the suitability of the vessel, venous anastomosis was performed. Seven male and 2 female patients were enrolled in this study. Appropriate dorsal veins for anastomosis could be found in 8 of 9 patients. All the replanted stumps survived without venous congestion and following additional procedures. A sizable volar or dorsal vein could not be found in 1 patient. The salvage technique was required in this patient. Dorsal veins in the lateral nail fold can be found easily because of the constant anatomical location. The new incision on the lateral nail fold provides not only sufficient operative field for anastomosis but also additional opportunity of successful venous anastomosis in the selected cases. The authors, therefore, propose this technique as an effective method for an alternative venous anastomosis in the zone I replantation.

    Adverse health effects of heavy metals are a public health concern, especially lead may cause negative health impacts to human fetal and infantile development. The lead concentrations in Pakistani pregnant women's nails, used as a biomarker, were measured to estimate the lead exposure. Thirteen nail samples out of 84 nails analyzed contained lead higher than the concentration (13.6 μg/g) of the fatal lead poisoning case, raising the possibility of an external contamination. Eye cosmetics such as surma are recognized as one of the important sources of lead exposure in Pakistan. We collected in Pakistan 30 eye cosmetics made in Pakistan, Saudi Arabia and western countries. As the metal composition analysis by energy dispersive X-ray fluorescence spectrometry revealed that some surma samples contained lead more than 96%, the surma might contaminate the nail specimen. Scanning electron microscopy observations showed that lead-containing surma consists of fine particle of galena (ore of lead sulfide) in respirable dust range (less than 10 μm). In addition, relative in vitro bioavailability of lead in the surma was determined as 5.2%. Thus, lead-containing surma consists of inhalable and bioavailable particles, and it contributes an increased risk of lead exposure. Moreover, the relationship between the surma and the lead-contaminated nails by lead isotope ratios analysis indicated the potential of lead contamination in nails by surma. These results suggest that lead in the nails was derived both from body burden of lead and external contamination by lead-containing surma. Therefore, nail is not suited as a biomarker for lead exposure in the countries where surma used, because we may overestimate lead exposure by surface lead contamination in the nail by surma.

    Stabilization of fractures with an intramedullary nail is a widespread technique in the treatment of femoral shaft fractures in adults; however, to ream or not to ream is still being debated. The primary objective of this study was to determine clinical results following unreamed versus ream intramedullary nailing of femoral fractures. Between January 2008 and August 2009, 50 patients with femoral shaft fractures were treated with unreamed or reamed femoral nails in our clinic. From this prospective single centre study, 16 patients were excluded due to insufficient follow-up data. According to the AO classification, fractures in this study were either type A or B. Dynamic proximal locking was performed in all cases. The remaining 34 patients were divided into two groups of 17 with ream or unream nailing. During and after the operation, we evaluated some variables in whole series. After statistical analyzes, we found that there were no differences in radiologic union time (P = 1) or full weight bearing time (P = 0.73) between ream and unream nailing. Nail breakage or iatrogenic fractures during nail insertion did not occur and we did not have any fat emboli in both groups but one secondary loss of reduction occurred in the unream group. Superficial infection after the operation was seen in one case which was treated successfully with antibiotics. In the ream group surgical time was about thirty minutes longer and differences were significant (P = 0.000). Patients had to pay more for ream nailing but the difference was not significant. We found no statistical difference between union time with or without reaming; on the other hand, there was significant increased operation length, blood loss and systemic changes in BP or So2 in the ream group versus the unream group. We advocate that unream nailing in traumatic femoral shaft fractures is a simple, safe and effective procedure with significant advantages, especially in multitrauma patients.

    We investigated the relationship between the development of postoperative anterior knee pain and the location of the nail in the proximal tibia in patients treated with locked intramedullary nailing for tibial diaphyseal fractures. Thirty patients were selected among those who underwent locked intramedullary nailing for tibial diaphyseal fractures, with exclusion of all other factors that might be associated with postoperative anterior knee pain. In all the patients, intramedullary nailing was performed using the transtendinous approach and both proximal and distal locking. The patients were evaluated in two groups: 10 patients (3 women, 7 men; mean age 38 + or - 14 years) had anterior knee pain, whereas 20 patients (5 women, 15 men; mean age 35 + or - 12 years) did not. The distances from the nail to the tibial plateau and anterior tibial cortex were measured on the lateral x-rays after a mean follow-up of 56.6 months and 45.2 months in patients with and without anterior knee pain, respectively. The two groups were similar with respect to gender and follow-up period (p>0.05). The mean distances from the nail to the tibial plateau and anterior tibial cortex were -11.5 + or - 7.9 mm and 3.7 + or - 5.4 mm, respectively, in patients with anterior knee pain. The corresponding distances were -8.8 + or - 7.3 mm and 6.5 + or - 4.7 mm in patients without knee pain. Neither of the distances showed a significant difference between the two groups (p>0.05). Our findings suggest that the distances from the nail to the tibial plateau and anterior tibial cortex do not have any role in the development of postoperative anterior knee pain.

    Pure hair and nail ectodermal dysplasia (PHNED) is a congenital condition characterized by hypotrichosis and nail dystrophy. Autosomal-recessive PHNED has previously been mapped to chromosomal region 12q12-q14.1, which contains the type II hair keratin and HOXC clusters. Hoxc13-null mice are known to develop hair and nail defects very similar to those seen in human PHNED. We performed whole-exome sequencing in a consanguineous Chinese family affected by PHNED and identified a homozygous nonse...

    Full Text Available Abstract Background The incidence of undetected radiographically iatrogenic longitudinal splitting in the anterior cortex during intramedullary nailing of the femur has not been well documented. Methods Cadaveric study using nine pairs of fresh-frozen femora from adult cadavers. The nine pairs of femora underwent a standardized antegrade intramedullary nailing and the detection of iatrogenic lesions, if any, was performed macroscopically and by radiographic control. Results Longitudinal splitting in the anterior cortex was revealed in 5 of 18 cadaver femora macroscopically. Anterior splitting was not detectable in radiographic control. Conclusion Longitudinal splitting in the anterior cortex during intramedullary nailing of the femur cannot be detected radiographically.

    In a prospective study, 50 fractures of the distal fifth of the tibia with additional involvement of the ankle joint in 18 patients were stabilized by unreamed nailing. In all, 90% of all fractures healed uneventfully without further surgical intervention after unreamed nailing, the highest ratio of complications (22%) being seen in all patients with distal fractures of the fibula without additional plating (of the fibula). Tibial fractures close to the ankle joint can be managed by unreamed nailing; distal fractures of the fibula should be additionally stabilized by fibular plating.

    Intramedullar nailing is now widely used for fractures of the tibia. Extension of nailing indications to proximal, distal, and comminuted fractures has led to a significant rate of complications. The purpose of this study was to analyze decortication and medial plating for the treatment of tibial nonunion after intramedullary nailing. Eighteen cases of aseptic tibial nonunion after nailing for fracture were treated in three women and fifteen men, mean age 39 years (19-57). The initial classification was open (n = 8), segmental (n = 3), single-focus (n = 15). The fracture site was inferior (n = 6), middle (n = 7), and superior (n = 2). Primary nailing used reaming in 15 cases (83%), unreamed in 3 (17%) static in 13 and dynamic in 5. Four plaster cabts were also applied. Complications were: infection (n = 1), compartmental syndrome (n = 2), tibial nerve palsy (n = 1), dysesthesia (n = 2), and protrusion of the nail into the knee (n = 1). Dynamization was performed in 11 patients, one with additional bone graft and fibulectomy. Repeated reamed nailing was performed in one patient. Seven nonunions were atrophic and 11 were hypertrophic. There were 13 malpositionings associated with the nonunion. Treatment of the nonunion was performed 300 days on average (90-900) after nailing: cancellous bone graft was associated with decortication in four cases because of bone loss (n = 3) or atrophic nonunion (n = 1). Union rate was 94%. Mean time for union was 108 days (80-180) with no significant difference (Student t-test) between atrophic (119 days) and hypertrophic (103 days) nonunion. Correction of the malposition was incomplete in seven patients, with angular malunion of less than 6 degrees in five patients and greater than 10 degrees in two. One late infection occurred and finally healed after external fixation and antibiotic therapy. No skin necrosis occurred. Five patients had pain on the hardware. Removal was performed in one time and pain resolved. Improvement of knee

    Intramedullary nailing of tibial shaft fractures is the preferred treatment of most displaced, unstable tibial shaft fractures. In open tibia fractures, direct exposure of the fracture segments for irrigation and debridement is required prior to fracture stabilization. We propose a method of provisional stabilization using commonly available implants placed through the associated traumatic open wound prior to intramedullary nailing. This technique, particularly helpful to surgeons operating with limited assistance, employs a temporarily applied 3.5-mm dynamic compression plate or limited contact dynamic compression plate implant secured with unicortical screws, allowing reaming and intramedullary nailing of a reduced, stabilized tibia fracture.

    Full Text Available Glomus tumor is an uncommon vascular tumor involving mostly subunguum of the thumb or the index finger. It commonly presents as a pink or purplish circumscribed nodule underneath the nail plate. Pain is paroxysmal in nature and precipitated often from exposure to cold or pressure/blunt trauma. Dystrophy of the nail plate occurs rarely. The described case, a 40-year-old woman, had dystrophic thumbnail ascribed to subungual glomus tumor that resembled median canaliform nail-dystrophy of Heller.

    In the management of proximal humeral fractures intramedullary implants with bent and straight shape of the proximal part of nail are available. Based on data from previous studies on bone distribution in the humeral head, we hypothesized, that higher densities might exist in the bone stock surrounding straight nails in comparison to their angulated counterparts. With a known positive correlation between bone density and mechanical stability, this could indicate potentially higher rigidity of osteosyntheses done with straight implants. We performed high resolution peripheral quantitative computed tomographies of the potential straight and bent implant bearing regions of 27 cadaveric proximal humeri. The acquired data were analyzed for differences between straight and bent Volumes of Interest as well as intra- and interindividual bone stock distribution. For both straight and bent volumes of interest a considerably declining bone mineral density was found in craniocaudal direction. Mean densities of bent volumes were significantly lower in comparison to their corresponding straight counterparts (p straight shaped implants can be assumed. Since we found a rapid decrease of bone density in cranio-caudal direction, intramedullary implants should be anchored as proximally in the subcortical area as possible to minimize the risk of displacement or cutout. The high correlation between the Volumes of Interest of the corresponding right and left sides could aid in preoperative planning when considering an intra- or extramedullary approach.

    Full Text Available Nonunion of long bones fixed with nails may result in implant failure. Removal of a broken intramedullary nail may be a real challenge. Many methods have been described to allow for removal of the broken piece of the nail. In this paper, we are reviewing the different techniques to extract a broken nail, classifying them into different subsets, and describing a new technique that we used to remove a broken tibial nail with narrow canal. Eight different categories of implant removal methods were described, with different methods within each category. This classification is very comprehensive and was never described before. We described a new technique (hook captured in the medulla by flexible nail introduced from the locking hole which is a valuable technique in cases of nail of a small diameter where other methods cannot be used because of the narrow canal of the nail. Our eight categories for broken nail removal methods simplify the concepts of nail removal and allow the surgeon to better plan for the removal procedure.

    Elastic stable intramedullary nailing (ESIN) is accepted widely for treatment of diaphyseal femur fractures in children. However, complication rates of 10 to 50 % are described due to shortening or axial deviation, especially in older or heavier children. Biomechanical in vitro testing was performed to determine whether two modified osteosyntheses with end caps or a third nail could significantly improve the stability in comparison to classical elastic stable intramedullary nailing in a transverse femur fracture model. We performed biomechanical testing in 24 synthetic adolescent femoral bone models (Sawbones®) with a transverse midshaft (diaphyseal) fracture. First, in all models, two nails were inserted in a C-shaped manner (2 × 3.5 mm steel nails, prebent), then eight osteosyntheses were modified by using end caps and another eight by adding a third nail from the antero-lateral (2.5-mm steel, not prebent). Testing was performed in four-point bending, torsion, and shifting under physiological 9° compression. The third nail from the lateral showed a significant positive influence on the stiffness in all four-point bendings as well as in internal rotation comparing to the classical 2C configuration: mean values were significantly higher anterior-posterior (1.04 vs. 0.52 Nm/mm, p < 0.001), posterior-anterior (0.85 vs. 0.43 Nm/mm, p < 0.001), lateral-medial (1.26 vs. 0.70 Nm/mm, p < 0.001), and medial-lateral (1.16 vs. 0.76 Nm/mm, p < 0.001) and during internal rotation (0.16 vs. 0.11 Nm/°, p < 0.001). The modification with end caps did not improve the stiffness in any direction. The configuration with a third nail provided a significantly higher stiffness than the classical 2C configuration as well as the modification with end caps in this biomechanical model. This supports the ongoing transfer of the additional third nail into clinical practice to reduce the axial deviation occurring in clinical practice.

    Twenty-seven patients with complex femoral fractures (combined shaft and proximal femoral fractures) were treated with a modified Grosse-Kempf slotted locking nail (cephalomedullary nail), wherein two screws were inserted in the hip. Four types of complex, multifocal femoral fractures were represented in the series. Eleven of the femoral shaft fractures were secondary to a previous, internally fixed, not yet united hip fracture (type I). Ten comminuted peritrochanteric fractures occurred in normal bone (type II). Three similar fractures were pathologic because of metastasis. Two patients had an ipsilateral fracture of the femoral shaft and the trochanteric area (type III), and one of the shaft and the femoral neck (type IV). Locking was made static in 24 cases. Additional cerclage wiring was used in three type II fractures. Five complications were as follows: one cutting out of a screw in the femoral head, two fractures of the nail, one deep venous thrombosis, and one wound hematoma. Reoperations were two salvage operations using a new nail and one evacuation of hematoma. One patient with multiple injuries and four elderly patients died within 2 months. Eighteen patients with fractures in normal bone were followed for a median of 20 (6 to 37) months. All fractures united. Two nails were removed. The end result was excellent in ten patients, good in seven, and fair in one (2-cm shortening and 20-degree external rotation). We conclude that a locked intramedullary construct with locking screws in femoral neck and distal femur controls a complex fracture situation well.

    In this work the open photoacoustic cell technique (OPC) is applied for measuring the thermal diffusivity (α) of human nail tips. Human nails are natural polymers that receive less attention in clinical analysis than other human body parts, although they are very interesting in giving information about some external diseases like dystrophies. Diagnosis and therapy with topic application of anti-fungal creams could be monitored since thermal properties are known. The OPC experiments in the low frequency range were done and through photoacoustic signal decay, the OPC model were used for fitting data in order to obtain the thermal diffusivity of the human nail in vitro. The average value for the nail tips used was found to be α ˜ (8.9 ± 1.3) × 10-4 cm^2/s, when different light source is used for photothermal heating. This average is of the order of that evaluated for the human skin.

    The presence of medically important fungi was studied in hallux nails scrapings obtained from 504 students (204 males, 300 females) of three universities in Cali. Specimens were examined by direct microscopic examination and fungal culture. Medically important fungi were found in 49 (9.7%) students, 24 (4.8%) had onychomycosis while the rest did not have nail lesions. Trichophyton rubrum was the most commonly isolated fungi in students with lesions, where as T. mentagrophytes predominated in healthy nails. Most of the students with fungi were males. The prevalence of fungi was higher in individuals between 26 and 35 years. No association was observed between fungi and practicing sports or undergoing pedicures. These results suggest that dermatophytes can be found in healthy hallux nails, which can be reservoirs of pathogenic fungi.

    2012-01-01

    Full Text Available A 19-year-old female patient sustained a closed spiral midshaft femoral fracture and subsequently underwent femoral intramedullary nail insertion. At followup she complained of difficulty in walking and was found to have a unilateral in-toeing gait. CT imaging revealed 30 degrees of internal rotation at the fracture site, which had healed. A circumferential osteotomy was performed distal to the united fracture site using a Gigli saw with the intramedullary femoral nail in situ. The static distal interlocking screws were removed and the malrotation was corrected. Two further static distal interlocking screws were inserted to secure the intramedullary nail in position. The osteotomy went on to union and her symptoms of pain, walking difficulty, and in-toeing resolved. Our paper is the first to describe a technique for derotation osteotomy following intramedullary malreduction that leaves the intramedullary nail in situ.

    A type 316L wrought stainless steel Jewett nail-plate is one of several implant designs for bridging fractures in the proximal end of the femur. A soldier received a high velocity projectile in the trochanteric region of the femur. He was treated for a subtrochanteric fracture and greater trochanteric bone loss. After 9 months, hip varus angulation was progressively increasing. A Jewett nail-plate was inserted after valgus osteotomy and bone grafting of the unhealed fracture. The nail-plate fractured three weeks after surgery. Optical and scanning electron microscopy related the origin of failure to an impactor failure and subsequent microscopic scoring of the nail-plate during insertion into the abnormally hard femoral head. Photomicrographs showing the implant failure and evidences of corrosion after the short time in the body are presented. 12 figs

    Tibial shaft fractures are among the most common long bone fractures in humans. The incidence is 1-2 per 100,000. The gold standard of treatment for AO type 42 A-C fractures is a locking intramedullary nail. The development of new implants has extended the indications for this minimally invasive technique, so that now AO types 41 and 43 can also be treated with special nails. Fixed-angle screw anchors increase primary stability and supplemental locking devices located proximally and distally extend the spectrum of use to metaphyseal fractures. The cannulated Targon TX titanium nail can be introduced, either with or without reaming. Using an operative video, the treatment of a tibial fracture with an intramedullary nail is demonstrated in stages and the operative steps further illustrated on artificial bone.

    For applying a magnesium alloy to nails in the guided bone regeneration (GBR) method, sufficient strength and appropriate degradation speed are required to fix a membrane. In the case, the nails are exposed to body fluid after penetrating the alveolar bone. Therefore, in this research, degradation behavior after penetration of magnesium-calcium alloy which is expected to possess high biocompatibility was investigated. As a result, the Mg-Ca alloy nails were degraded inhomogeneously after immersion for 4 weeks in simulated body fluid. The degraded portions corresponded to the distribution of residual strain estimated by finite element analysis. Mg-Ca nails without precipitates possessed comparatively gradual degradation rate. It can be also confirmed that the region with residual strain degraded preferentially when compared the CT images and the residual strain distribution after penetration.

    Intramedullary fixation of fibular fractures has been reported in the literature. Its advantages include ease of fixation as well as minimal soft tissue disruption. Various implants have been described, including the Inyo nail and Rush rods. Several studies have examined their use in older people with osteoporotic bone as well as in instances where soft tissue preservation is of concern. To our knowledge, no technique has been described using flexible titanium elastic nails (TENS) (Synthes; Paoli, PA). We illustrate such a technique as well as a case report that demonstrates our experience. Insertion of flexible titanium elastic nails requires attention to detail with preservation of the peroneal tendons and their sheath. While such a construct cannot control rotation, it can preserve length as well as prevent varus and valgus displacement. Future endeavors could focus on the biomechanical principles of intramedullary fibular fixation with TENS nails.

    Full Text Available Fusarium spp are non-dermatophytic hyaline moulds found as saprophytes and plant pathogens. Human infections are probably a result of various precipitating predisposing factors of impaired immune status. Immunocompetent individuals of late are also vulnerable to various unassuming saprophytic and plant pathogens. To stress the need to identify correctly and institute appropriate antifungal therapy in newly emerging human fungal infectious agents. Repeated mycological sampling of the skin and nails of the suspected fungal infection were processed as per the standard format including direct microscopy and fungal culture on Sabouraud′s dextrose agar. The fungus was isolated as Fusarium solani. Fusarium is an important plant pathogen and soil saprophyte. Infection is acquired by direct inoculation or inhalation of spores. It is associated with a variety of diseases like keratitis, onychomycosis, eumycetoma, skin lesions and disseminated diseases.

    In treating patients who present with an extensive non-union due to infected intramedullary nail, bone healing can be achieved within a few weeks through a policy of active management. Following excision of the infected tissue and thorough irrigation, the fracture site is stabilized by a plate fixation and a packet with cancellous bone. The wound overlying the bone is left open to granulate. No complications were observed during the course of healing in 7 cases (5 tibia, 2 femur) managed this way. The method is based on classical principles of orthopedics and the treatment of infection. Such has been its impressive success, that it would seem to warrant not only close attention but also strong recommendation.

    2006-01-01

    In a prospective, randomized trial we compared the trochanteric gamma nail (TGN) and the dynamic hip screw (DHS) in the treatment of 146 intertrochanteric fractures. Follow-up was after four and 12 months. The operation time was significantly shorter in the DHS group. At discharge the need...... for walking aids was less in the DHS group. There were no differences in intraoperative blood loss, medical complications, mortality or length of hospital stay. Major fracture complications occurred twiceas often in the TGN group compared with the DHS group, however they were not statistically significant....... Any potential for the TGN leading to a less invasive procedure and a more rapid postoperative mobilisation could not be demonstrated. Compared with the TGN we prefer the DHS for most intertrochanteric fractures in a setting where the majority of these fractures are treated by younger doctors...

    Full Text Available Background: Closed reduction & plaster is standard and effective form of treatment in majority of paediatric tibial shaft fractures. Operative intervention is necessary in unstable fractures, open fractures, poly trauma patients and compartment syndrome or severe soft tissue compromise. Historically, external fixation and plating were the treatment options available, but having complications like infection, overgrowth and refracture. Reamed locked intramedullary nails pose unnecessary risk to the proximal tibial growth plate. Flexible intramedullary nailing in long bone fractures in children has gained wide spread popularity because of its clinical effectiveness & low risk of complications. Methodology: This is a study of 15 patients of unstable tibial shaft fractures in children treated with Ender’s nailing. 12 were closed & 3 were open grade I fractures with only punctured wounds. Age was ranging from 7 to 16 yrs. There were 8 middle third, one upper third and 6 distal third shaft tibia fractures. In all patients 3.5 Ender’s nails were used, two nails in 11 patients and three nails in 4 patients there was no post-operative wound infection. Average operative time was 40 minutes and average blood loss was 35 cc. Results: Average union time was 9 wks. All fractures united without 2nd operative intervention. In 2 patients there was some proximal migration of nails causing some knee irritation. In all patients implant removed 6 to 7 months after surgery. At final follow-up there were full knee & ankle movements. 2 patients had more than 50 malalignment in A-P or M-L plane. No rotational deformity, no limb length discrepancy or physical arrest. Conclusion: Ender’s nailing is an effective method of treatment in these cases, which allows rapid healing of tibial shaft fractures with an acceptable rate of complications. There is short learning curve with this treatment and implants are inexpensive.

    2017-07-01

    Full Text Available INTRODUCTION: Humerus shaft fractures in adults can be managed conservatively with functional braces or operatively with plate osteosynthesis or with intramedullary nailing. Conventionally humerus intramedullary nailing is done either using humerus interlocking nails or Enders nails. In this study we analyse the outcome of humerus shaft fractures (upper and middle third managed with closed ante- grade intramedullary titanium elastic nailing in terms of union rates, union time, functional results and complications. MATERIALS AND METHODS: A retrospective analysis of 25 patients treated with ante-grade intramedullary titanium elastic nailing was done during the period of August 2014 to June 2016 at our tertiary care centre. Skeletally mature patients with closed and acute fractures of the upper and middle shaft humerus of both sexes were included in the study. RESULTS: Twenty-five (100% fractures united with an average consolidation time of 14.98 weeks (10-32 weeks, and no fractures ended in non-union. Nail impingement was seen in two (8%, shoulder stiffness in one (4%. Functional results were excellent in 22 (88%, moderate in two (8% and poor in one (4%. There were 17 males and eight females with an average age of 39.08 years (range: 18-65 years. The average duration of hospital stay was 3.84±2.30 days. CONCLUSION: Closed ante-grade intramedullary titanium elastic nailing offers a safe and reliable method of fixing fractures of upper humeral shaft in adults. This method provides early fracture union, high union rates and less complications, in addition to early rehabilitation and reduces the hospital stay.

    Intramedullary nailing is an accepted treatment for the fixation of femoral and tibial shaft fractures. There is a low but significant incidence of intraoperative complications during intramedullary nailing. During this procedure, a medullary tube may be used to exchange the bent olive-tipped reaming guidewire for the straight guidewire. A review of the literature found only one report of a fracture of the medullary tube. Two cases in which the medullary tube fractured into multiple pieces are presented.

    2014-01-01

    Full Text Available Background: Onychomycosis of the fingernails and toenails is generally caused by dermatophytes and yeasts. Toenail mycoses involve mainly dermatophytes but when Candida is also involved, the strain most commonly isolated worldwide is C. albicans. Aims: To determine Candida strains prevailing in onychomycosis. Materials and Methods: A retrospective, observational and descriptive study of fungal cultures retrieved from the registry of the microbiology laboratory of the Pontificia Universidad Católica was performed. Specimens obtained from patients attending the healthcare network between December 2007 and December 2010 was analyzed. Statistical Analysis: A descriptive statistical analysis was performed. Results: Candida was retrieved from 467 of 8443 specimens (52% fingernails and 48% toenails. Cultures were negative in 5320 specimens (63.6%. Among Candida-positive cultures, parapsilosis was the most commonly isolated strain with 202 cases (43.3%. While isolates of Candida guillermondii were 113 (24.2%, those of Candida albicans were 110 (23.6%, those of spp. were 20 (4.3% and there were 22 cases of other isolates (4.71%. Among the 467 patients with positive cultures for Candida, 136 (29,1% were men and 331 (70,9% were women. All patients were older than 18 years old. Clinical files were available for only 169 of the 467 patients with positive cultures for Candida. For those, age, gender, underlying illnesses and use of immunossupresive agents during the trial was reviewed. Conclusions: The present study shows that both C. parapsilosis as well as C. guillermondii appear as emerging pathogens that would be in fact taking the place of C. albicans as the most commonly isolated pathogen in patients with Candida onychomycosis. The relative percentage of C parapsilosis increases every year. Identification of Candida strains as etiological agents of nail candidiasis becomes relevant to the management both nail as well as systemic candidiasis, in view of

    Finger nails from twenty normal people and three with carcinoma of nasopharynx were studied by Fourier Transform Infrared (FTIR) technique. The results showed that there are obvious differences between FTIR spectra of them in spectral parameters such as frequency, intensity and band shape etc. The most striking differences in the spectra were observed in the change of amide II, the disappearance of delta(s) (CH3) peak, and at 874.0 cm(-1) whether appeared an absorption peak. The changes involving the phosphate symmetric stretching nu(s, PO2-) and asynmmetric stretching nu(as, PO2-) modes, the CH3 and CH2 groups stretching (v(s, CH2), nu(as, CH3)) bending (delta (CH3)) modes and the C-O stretching nu (C-O) mode were discussed. In addition, the changes of structure of hydrogen-bonding of nucleic acid and cell proteins and the packing and the conformational structure of the membrane lipids were analysed. The average wave number of band of nu(s) (PO2-) shifted from 1080.0 to 1077.6 cm(-1) and that of nu(as) (PO2-) shifted from 1239.4 to 1238.4 cm(-1), which indicated that the degree of hydrogen-bonding formed by oxygen atom of the phosphodiester groups of nucleic acids was weakened. The average wave number of band of delta (CH2) of membrane lipids shifted from 1453.1 to 1453.7 cm(-1), and its peak intensity was slightly enhanced, which suggested that the conformational structure of the methylene chains of membrane lipids is more disordered than in normal nail.

    Abstract Background and objective: Intramedullary nailing is commonly used for treating femoral shaft fractures, one of the most common long bone fractures in adults. The reamed intramedullary nail is considered the standard implant for femoral fractures. This meta-analysis was performed to verify the superiority of reamed intramedullary nailing over unreamed intramedullary nailing in fractures of the femoral shaft in adults. Subgroup analysis of implant failure and secondary procedure was also performed. Methods: Electronic literature databases were used to identify relevant publications and included MEDLINE (Ovid interface), EMBASE (Ovid interface), and the Cochrane Central Register of Controlled Trials (CENTRAL; Wiley Online Library). The versions available on January 30, 2016, were utilized. Only human studies, which were designed as randomized controlled clinical trials, were included. Two authors independently evaluated the quality of original research publications and extracted data from the studies that met the criteria. Results: Around 8 randomized controlled trials involving 1078 patients were included. Reamed intramedullary nailing was associated with shorter time to consolidation of the fracture (SMD = –0.62, 95% CI = –0.89 to –0.35, P fractures using reamed intramedullary nailing is recommended.

    In a prospective study, 53 fractures of the distal fifth of the tibia were stabilized by unreamed nailing. Additional involvement of the ankle joint occurred in 18 patients. 50 patients returned for follow-up. In 30 patients tibia and fibula were fractured at the same (distal) level; in 20 patients the fracture of the fibula was located more proximally. In 12 patients the fractures extended into the tibial pilon. Severe soft tissue damage was seen in 24 fractures (18 open, 6 closed). Ninety percent of all fractures healed uneventfully without further surgical intervention after unreamed nailing. In two patients the unreamed nail had to be exchanged for a reamed tibial nail. Bone grafting and secondary dynamization of the nail by removal of a proximal interlocking bolt were performed in one case each. Thirty-one fractures healed in anatomical position. Valgus or varsus angulation of less than 5 degrees occurred in 18 patients. One fracture healed with rotatory angulation of 15 degrees. The highest rate of complications (22%) was seen in patients with distal fractures of the fibula without additional plating (of the fibula). There was no deep infection. Tibial fractures close to the ankle joint can be managed by unreamed nailing. Distal fractures of the fibula should be stabilized by additional plating. Because of the unreamed technique of implantation this procedure can also be used in grade II or III open fractures.

    Full Text Available BACKGROUND Distal tibial fracture often present a challenge to the orthopaedic surgeon. The best option for surgical management of distal tibial fracture is still unclear, whether nail or plate. MATERIALS AND METHODS The study consists of 24 patients of distal tibial fracture treated either with reamed intramedullary nails or locked plating/MIPPO with open reduction method or minimally-invasive techniques. RESULTS 24 patients included in the present study were divided into two groups as nailing group A and plating group B. Nailing group included 12 patients and plating group included 12. Age range of patients was 21-62 years. Most common mode of trauma in both groups as RTA followed by accidental fall in 2 cases. The average time for union and weightbearing was 19 weeks in group A and 20.08 weeks in group B. Complications like malalignment, more surgical time were seen in group A and surgical site infection, skin necrosis, prolonged immobilisation were seen in group B. CONCLUSION Both IM nailing and plating are optional methods of treatment. Intramedullary nailing in distal tibial fractures result in early mobilisation is an easier technique, more economical and has fewer complications rate. Plating is preferred in cases where fracture is very close to ankle mortise and associate with higher rate of wound complications.

    Full Text Available The nail provides a functional protection to the fingertips and surrounding tissue from external injuries. The nail plate consists of three layers including dorsal, intermediate, and ventral layers. The dorsal layer consists of compact, hard keratins, limiting topical drug delivery through the nail. In this study, we investigate the application of fractional CO2 laser that produces arrays of microthermal ablation zones (MAZs to facilitate drug delivery in the nails. We utilized optical coherence tomography (OCT for real-time monitoring of the laser–skin tissue interaction, sparing the patient from an invasive surgical sampling procedure. The time-dependent OCT intensity variance was used to observe drug diffusion through an induced MAZ array. Subsequently, nails were treated with cream and liquid topical drugs to investigate the feasibility and diffusion efficacy of laser-assisted drug delivery. Our results show that fractional CO2 laser improves the effectiveness of topical drug delivery in the nail plate and that OCT could potentially be used for in vivo monitoring of the depth of laser penetration as well as real-time observations of drug delivery.
