Associations of hemoglobin and change in hemoglobin with risk of incident hip fracture in older men and women: the cardiovascular health study.

In a multi-site longitudinal cohort study, decreasing hemoglobin was associated with increased hip fracture risk in men. Anemia was associated with hip fracture in men and in African American women. Decreasing hemoglobin may be a marker of progressing bone fragility, making its serial measurement useful for fracture risk stratification. INTRODUCTION: Hematopoiesis and bone health are interdependent. Anemia has been associated with risk of fracture in humans. To further elucidate this relationship, we hypothesized that decreasing hemoglobin could indicate defective hematopoiesis and would also predict fracture risk. METHODS: We performed a prospective analysis from study baseline (1992) of the Cardiovascular Health Study, a multi-site longitudinal cohort study. A total of 4670 men and women, ages >65 years, who were able to consent and not institutionalized or wheelchair bound, had hemoglobin (Hb) measured in 1992. For 4006 subjects, Hb change from 1989 to 1992 was annualized and divided into sex-specific quartiles. Incident hip fractures were verified against Medicare claims data during a median follow-up of 11.8 years. RESULTS: Nested Cox proportional-hazard models estimated association of hip fracture with anemia (men Hb <13 g/dL, women Hb <12 g/dL) and separately, greatest Hb decrease (versus others). Anemia was associated with increased hip fracture risk in all men (HR 1.59; 95% CI 1.01-2.50) and African American women (HR 3.21; 95% CI 1.07-9.63). In men, an annualized Hb loss of >0.36 g/dL/year was associated with a higher risk of hip fracture (HR 1.67; 95% CI 1.10-2.54), which was lessened by anemia at the start of fracture follow-up (HR 1.53; 95% CI 0.99-2.39). CONCLUSIONS: Decreasing Hb may be an early marker for subsequent hip fracture risk in men, which may be less informative once an anemia threshold is crossed. Only African American women with anemia had increased hip fracture risk, suggesting a race difference in this relationship.

The potential of salivary biomarkers for predicting the sensitivity and monitoring the response to nonsurgical periodontal therapy: A preliminary assessment.

BACKGROUND AND OBJECTIVE: The response to nonsurgical periodontal treatment varied among patients. This study assessed the potential of salivary biomarkers for predicting the sensitivity and monitoring the response to nonsurgical periodontal therapy. MATERIAL AND METHODS: This study recruited 34 participants with severe chronic periodontitis (the test group) and 20 participants without periodontal destruction in any teeth (the control group) from September 6, 2013 to August 25, 2017. Participants in the test group received nonsurgical periodontal therapy and were further divided into 2 subgroups of 17 low responders and 17 high responders, based on probing depth reduction. Clinical periodontal parameters were recorded, and saliva samples were harvested before and after nonsurgical periodontal therapy. Salivary biomarkers, including interleukin (IL)-1beta (IL-1ß), IL-1 receptor antagonist (IL-1ra), IL-6, IL-8, platelet-derived growth factor-BB, vascular endothelial growth factor, MMP-8, MMP-9, C-reactive protein, and lactoferrin were analyzed. RESULTS: Compared with participants in the control group, participants in the test group had significantly greater periodontal pocket depth, clinical attachment level, and salivary IL-1ß and MMP-8 levels, and all of these parameters were significantly reduced after nonsurgical periodontal therapy. The pretreatment levels of IL-1ß, MMP-8, and lactoferrin were significantly higher in participants of the high-responder subgroup than participants of the low-responder subgroup.Based on the analysis from a dichotomous table, MMP-8 and lactoferrin showed odds ratios of 5.76, with 71% sensitivity and 71% specificity, and statistical significance (P = .02) for discriminating between the high- and low-responder subgroups. CONCLUSION: Salivary IL-1ß and MMP-8 might be useful for diagnosing periodontitis and monitoring the recovery of periodontitis following nonsurgical periodontal therapy. MMP-8 and lactoferrin showed potential for predicting the sensitivity to the treatment.

Enhancing the effectiveness of diabetes self-management education: the diabetes literacy project.

Patient empowerment through self-management education is central to improving the quality of diabetes care and preventing Type 2 Diabetes. Although national programs exist, there is no EU-wide strategy for diabetes self-management education, and patients with limited literacy face barriers to effective self-management. The Diabetes Literacy project, initiated with the support of the European Commission, aims to fill this gap. The project investigates the effectiveness of diabetes self-management education, targeting people with or at risk of Type 2 Diabetes in the 28 EU Member States, as part of a comprehensive EU-wide diabetes strategy. National diabetes strategies in the EU, US, Taiwan, and Israel are compared, and diabetes self-management programs inventorized. The costs of the diabetes care pathway are assessed on a per person basis at national level. A comparison is made of the (cost)-effectiveness of different methods for diabetes self-management support, and the moderating role of health literacy, organization of the health services, and implementation fidelity of education programs are considered. Web-based materials are developed and evaluated by randomized trials to evaluate if interactive internet delivery can enhance self-management support for people with lower levels of health literacy. The 3-year project started in December 2012. Several literature reviews have been produced and protocol development and research design are in the final stages. Primary and secondary data collection and analysis take place in 2014. The results will inform policy decisions on improving the prevention, treatment, and care for persons with diabetes across literacy levels.

Hindering factors and suggestions related to organ donation decisions: perspective of the Taiwan Ali-Shan Tsou aboriginal tribe.

BACKGROUNDS AND AIMS: Ali-San Tsou (AST) is one of leading aboriginal tribes in Taiwan with traditional godly beliefs related to life and death. Lacking related knowledge, health professionals (HPs) often failed to help them reach good dying or organ donation (OD). This study aimed to explore hindering factors and suggestions related to OD for good dying from Taiwan AST's own perspective. METHODS: An explorative qualitative design was employed using a purposive sample of the AST tribes from Taiwan. Data were collected with AST residents by face-to-face interviews and analyzed by content analysis. RESULTS: Thirty AST residents (16 females and 14 males) with ages ranging from 28 to 78 (mean, 54.5) years completed interviews. Of them, 85% reported various diseases. In this study 73% were Catholics and Christians, 17% held traditional godly believes, and 10% had no religious affiliation. Eight hindering factors were reported: (1) limited information about organs and OD; (2) no qualified organs for donation; (3) worry about lack of forgiveness by ancestors; (4) tribe elders who might not accept concept of OD; (5) intact bodies were required at home during spirit-companion rituals; (6) earth burial with intact bodies was preferred; (7) bodies due to accidental and bad death were impermissible for OD; and (8) worry about possession by the donor's spirit. Seven suggestions were also reported for HPs to enhance AST's OD decisions: (1) starting with friendship and a caring relationship; (2) providing spiritual support from reverent religions; (3) stressing good deeds and honoring tribe folks by OD; (4) avoiding accidental/bad death; (5) providing relevant modern medical knowledge of human organs and OD; (6) introducing OD as part of a good-dying care plan; and (7) demonstrating a respectful discussion mindset about OD. CONCLUSIONS: Eight hindering factors and 7 types of suggestions for enhancing AST aboriginal people's OD decisions were first explored in this project. In the future, HPs are encouraged to invite AST to share the concepts of OT and try to clarify the related concerns with respect for their cultural contexts. With mutual respect, the efforts of sharing and integrating OD into good-dying care would be more possible.

Evidence for direct CP violation in B±â†’ηh± and observation of B0→ηK0.

We report measurements of the branching fractions and CP asymmetries for B(±)→ηh(±) (h=K or π) and the observation of the decay B(0)→ηK(0) from the final data sample of 772×10(6) B ̅B pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The measured branching fractions are B(B(±)→ηK(±))=(2.12±0.23±0.11)×10(-6), B(B(±)→ηπ(±))=(4.07±0.26±0.21)×10(-6), and B(B(0)→ηK(0))=(1.27(-0.29)(+0.33)±0.08)×10(-6), where the last decay is observed for the first time with a significance of 5.4 standard deviations (σ). We also find evidence for CP violation in the charged B modes, A(CP)(B(±)→ηK(±))=-0.38±0.11±0.01 and A(CP)(B(±)→ηπ(±))=-0.19±0.06±0.01 with significances of 3.8 σ and 3.0 σ, respectively. For all measurements, the first and second uncertainties are statistical and systematic, respectively.

Functional outcome assessment after open tennis elbow release: what are the predictor parameters?

INTRODUCTION: Open surgical release remains the gold standard for treatment of recalcitrant lateral epicondylitis (tennis elbow). We aimed to evaluate the potential impact of perioperative factors on outcome after open surgical release for tennis elbow. METHODS: All patients without elbow dislocation who underwent open surgical release for tennis elbow from January 2000 to June 2006 were included in the study. Comorbidities and associated pathologies of the upper limb as well as postoperative pain score, range of motion, evidence of instability, recurrence and other complications were noted. RESULTS: There were 37 female and 24 male patients aged 22-60 (44.95 +/- 7.34) years. Five (8.1 percent) patients had diabetes mellitus. The mean duration of symptoms before surgery was 16.8 +/- 15.3 (range 2-84) months. The average duration of follow-up was 23.0 +/- 34.5 (range 0.4-206) months. Overall, 59 (96.7 percent) patients reported improvement of symptoms post surgery. Median grip strength on the operated and unoperated sides were 25.5 +/- 9.0 (range 10.5-44.0) KgN and 23.7 +/- 9.1 (range 9.3-41.5) KgN, respectively. Patients with diabetes mellitus had significantly higher pain scores (2.80 versus 0.36, p-value less than 0.01, 95 percent confidence interval [CI] 1.2-3.7), reduced grip strength (0.91 KgN versus 1.06 KgN, p-value is 0.038, 95 percent CI 0.29-0.01) and higher recurrence rates (40 percent versus 7.7 percent, p-value is 0.018). CONCLUSION: Diabetes mellitus has a negative effect on surgical outcome in terms of pain scores, grip strength ratio and recurrence rate. This should be reiterated during preoperative counselling.

Comparative effects of acupressure at local and distal acupuncture points on pain conditions and autonomic function in females with chronic neck pain.

Acupressure on local and distal acupuncture points might result in sedation and relaxation, thereby reducing chronic neck pain. The aim was to investigate the effect of acupressure at local (LP) and distal acupuncture points (DP) in females with chronic neck pain. Thirty-three females were assigned to three groups: the control group did not receive any stimuli, the LP group received acupressure at local acupuncture points, GB 21, SI 14 and SI 15, and the DP group received acupressure at distal acupuncture points, LI 4, LI 10 and LI 11. Verbal rating scale (VRS), Neck Disability Index (NDI), State-Trait Anxiety Inventory (STAI), muscle hardness (MH), salivary alpha-amylase (sAA) activity, heart rate (HR), heart rate variability (HRV) values and satisfaction due to acupressure were assessed. VRS, NDI, STAI and MH values decreased after acupressure in the LP and the DP group. HR decreased and the power of high frequency (HF) component of HRV increased after acupressure in only the LP group. Although acupressure on not only the LP but also the DP significantly improved pain conditions, acupressure on only the LP affected the autonomic nervous system while acupuncture points per se have different physical effects according to location.

A method for the non-invasive assessment of chest wall growth in pectus excavatum patients.

INTRODUCTION: Various scales and measurement methods including X-rays and computed tomography (CT) have been used to quantify the degree of deformity in pectus excavatum. This study describes a non-invasive method for recording the deviation of the anterior chest wall (ACW) in pectus excavatum (PE) patients. Data obtained using this non-invasive method were compared with CT data. MATERIALS AND METHODS: Twenty-one patients treated at our institutions between June 2008 and February 2009 were enrolled in this study. All patients underwent CT and thermal plastic strip measurement. A thermal plastic strip was positioned and taped to the supine patient's ACW at the skin level from the posterior axillary line, over the depressed sternum, to the contralateral posterior axillary line and used to create a casting of the ACW. RESULTS: The funnel index (FI) was defined as the width of the ACW divided by its height; the concave index (CI) was defined as the breadth of the depressed area of the funnel chest divided by its depth. Pearson's correlation coefficient was used to compare the FI and CI obtained with the thermal plastic strip method and with CT; measurements obtained with both methods were found to correlate well (FI: r (2)=0.965; CI: r (2)=0.947). CONCLUSIONS: The thermal plastic strip measurement method provides a two-dimensional record of the shape of the anterior chest wall. The measurement can be repeated, does not involve the patient being exposed to radiation, and offers a good longitudinal assessment of chest wall growth in PE patients.

Current status of hematopoietic stem cell transplantation in Taiwan.

In Taiwan, hematopoietic SCT (HSCT) has been used to treat patients with hematological diseases since 1983. Since then, more than 2200 patients have undergone HSCT in 15 large hospitals. The disease entities included acute leukemia in 37% of cases, non-Hodgkin's lymphoma in 26%, CML in 10%, multiple myeloma in 7% and severe aplastic anemia in 6%. The conditioning regimens used were mainly myeloablative (84% of cases). Non-myeloablative regimens were fludarabine-based. The average age of allogeneic recipients was at least 10 years older than those in the era before their application. The grafts of all patients were derived from peripheral blood in 85% of cases, BM in 13% and cord blood (CB) in 2%. Forty percent of HSCT patients received autologous grafts, whereas more than 25% of allogeneic HSCT patients received grafts from unrelated donors, and overall, there were more than 200 Taiwan HSCT recipients. Currently, CB has been used successfully in pediatric patients with thalassemia major and also in adult patients with hematological malignancy. After transplantation, there was a relatively lower prevalence of acute GVHD. However, a relatively higher proportion of hepatitis B carriers in the recipients had led to a higher incidence of viral reactivation and clinical hepatitis, which was dramatically decreased following lamivudine prophylaxis. In conclusion, HSCT has been successfully adapted to routine clinical care in Taiwan. Several important findings contributing to the progress of HSCT in the past two decades have also been noticed on this island.

Prospective assessment of changing from placebo to IFN beta-1a in relapsing MS: the PRISMS study.

The efficacy of interferon (IFN) beta has been shown in several placebo-controlled, parallel-group studies in relapsing-remitting multiple sclerosis (RRMS). PRISMS, the largest such study to date, clearly demonstrated the efficacy of IFN beta-1a on all outcome measures over 2 years during the placebo-controlled, parallel-group phase. However, this study's placebo-crossover design also provided us with a unique opportunity to conduct a prospective within-group assessment, eliminating the impact of inter-patient variability. At the start of year 3, patients receiving placebo during years 1-2 were re-randomized in a dose-blinded fashion to receive IFN beta-1a, 22 or 44 mcg subcutaneously three times weekly, during years 3 and 4. Clinic visits occurred 3-6 monthly and T2 MRI scans were obtained after 1 and 2 years on therapy. Comparison of the mean relapse count per patient over 2 years (the primary outcome measure) during time on placebo (years 1 and 2) with that during active treatment (years 3 and 4) revealed a decrease from 2.6 to 1.2 in both dose groups (54% relative reduction; p<0.001). Disability progression, T2 MRI lesion activity and accumulation of T2 lesion burden were also significantly improved with therapy (p<0.01). No new safety issues were noted. These data provide further support for IFN beta-1a's efficacy in RRMS. The ability to detect significant treatment effects with reduced patient numbers in this type of before/after analysis, may be due to the reduction in inter-patient variability.

Assessment of blood-induced cartilage damage in rabbit knees using scanning electron microscopy.

PURPOSE: To investigate the harmful effects of a single episode of intra-articular bleeding on articular cartilage of rabbit knees using scanning electron microscopy. METHODS: Autologous blood was injected into the right knee joints of 18 New Zealand white rabbits. Surface and cellular damages were examined by the scanning electron microscope (n=9) and light microscope (n=34), respectively. The injected right knees were then compared with the corresponding control left knees at one, 3, and 6 weeks after the blood injection. RESULTS: The articular surface of the injected knees turned uniformly rough with multiple pits after one week. Maximal changes with elevations and depressions were observed at 3 weeks. These changes reversed at 6 weeks with the irregularities smoothing out. A similar pattern of transient cartilage damage was noted histologically. CONCLUSION: Both scanning electron microscopic and light microscopic findings suggest that a single episode of intra-articular bleeding leads to articular cartilage damage but this appears to be reversible. Our findings of transient damage to the articular cartilage suggest that there is no need for intra-articular evacuation and washout following an acute episode of haemarthrosis.

Analysis of the spatial distribution of polarized light backscattered from layered scattering media.

The scattering of polarized light from a two layer scattering medium is investigated using Monte Carlo simulations. First order and normalized second order moments are used to analyze the spatial properties of the emerging light in different polarization states. Linearly and circularly polarized illumination is used to probe different depths. Absorption and layer thickness are varied and it is demonstrated that the determination of these values is aided by the inclusion of polarization information. The lateral and depth localization of light by polarization subtraction is also quantified. Potential applications of these techniques are burn depth and melanoma thickness measurements.

Improvement of health outcomes after continued implementation of a clinical pathway for radical nephrectomy.

The clinical pathway is an important tool for outcome management. We evaluated the overall effects of the continued implementation of a clinical pathway for radical nephrectomy on the length of hospital stay, admission charges, and the quality of medical care. The data obtained from the second-year implementation (group 3) of the clinical pathway were compared with the data from the first-year implementation (group 2) and the year preceding implementation (group 1). Thirty-seven consecutive patients with renal cell carcinoma underwent radical nephrectomy in group 1, 47 in group 2, and 55 in group 3; all were enrolled in this study. The length of hospital stay, average admission charges, and 8 quality indicators were measured in these patients. We also evaluated the variances in the implementation of the clinical pathway. The mean length of stay decreased by 14.0% (P = 0.0048) in group 2, and by 15.8% (P= 0.0014) in group 3, when compared to group 1. The total admission charges significantly decreased by 19.0% (P = 0.001) in group 2, and by 27.9% (P < 0.0001) in group 3, compared to the charges for group 1. A continued decrease in charges for operation and anesthesia, laboratory, pharmacy, and others were found 2 years after implementation of the clinical pathway. Among the 8 quality indicators, 2 were continuously improved in the second-year implementation of the clinical pathway, 2 were improved significantly in the second-year implementation only, and 4 showed no significant change at all. Variances from the clinical pathway decreased significantly after continued implementation. Continued implementation of the clinical pathway for radical nephrectomy can improve a physician's practice continuously by decreasing the length of hospital stay, admission charges, and variances, and by improving quality. However, the improved results after implementation of the clinical pathway should be maintained carefully to assure good health care.

Preclinical cost analysis of orthopaedic implants: a custom versus standard cementless femoral component for revision total hip arthroplasty.

A preclinical cost analysis method was introduced to assess the cost effectiveness of using a custom implant instead of standard "off-the-shelf" implants for revision total hip arthroplasty. Finite element models of proximal femur-implant systems were constructed and an array of environmental factors, including loads and bone properties, was incorporated into a computer experiment to evaluate relative motion between implant and bone. Implant performance related cost was then determined from relative motion measures using a quality loss function. Unit manufacturing cost was added to implant performance cost to determine the cost difference between the two implants. The reduction in relative motion achieved by the custom implant with respect to an equivalent-lengthed standard implant justified its additional unit manufacturing costs. In response to these results and suggestions by surgeons, we increased the length of the standard implant by 50 mm and performed an identical series of analyses. We found that increasing the stem length to 120 mm substantially decreased the relative motion of the standard implant to values less than for the custom implant. This case study provides preliminary evidence that a surgical inventory consisting of longer-stemmed standard implants or modular distal stems is more cost effective than designing custom devices on a case-by-case basis. Additional design studies are warranted before generalizing such a claim.

Review: emotional and behavioral functioning in phenylketonuria.

OBJECTIVE: To examine 17 studies of the psychological sequelae of early-treated phenylketonuria (PKU) with emphasis on the impact of dietary control on functioning. Two questions are addressed: (1) What is the typical psychological profile associated with PKU? (2) Is emotional and behavioral disturbance more prevalent in PKU-affected individuals compared to appropriate controls? METHOD: Computerized searches of PsycINFO identified studies using behavioral, personality, and diagnostic measures. RESULTS: Findings converge upon a profile including attentional difficulties, depression, anxiety, and low self-esteem. Methodological constraints limit conclusions regarding the nature and severity of observed difficulties. A single study has used comparison groups appropriate for the simultaneous examination of the questions posed (Waisbren and Levy, 1991). CONCLUSIONS: We discuss results using a biopsychosocial framework, addressing the factors and processes that may influence emotional and behavioral functioning in this neurodevelopmental disorder. We outline potential lines of new investigation that address critical methodological factors.

Effects of implementation of 18 clinical pathways on costs and quality of care among patients undergoing urological surgery.

PURPOSE: We evaluated the effects on the costs and quality of care of implementation of 18 clinical pathways for urological operations. MATERIALS AND METHODS: From April 1997 to March 1998 patients undergoing 1 of 18 urological operations were treated according to clinical pathways. The outcomes in terms of length of hospital stay and admission charges of these patients were compared with those of patients treated between April 1996 and March 1997 before clinical pathways were implemented. We also selected 7 clinically relevant quality indicators to assess the quality of care before and after clinical pathway implementation. RESULTS: Of the 1,784 patients undergoing urological surgery from April 1997 to March 1998, 1,382 (77.5%) were treated according to 1 of the 18 clinical pathways. Before implementation 1,279 of 1,615 patients (79.2%) underwent these procedures. The length of hospital stay decreased from 5.5 to 4.9 days (p < 0.01) and the average hospital admission charges decreased by 12.9% (p < 0.01) after implementation. Five of the quality indicators, including the rate of surgical complications, were significantly improved after pathway implementation. The hospitalization rate was not affected (1.3 before versus 0.8% after implementation, p = 0.18). Variations from the clinical pathways occurred in 543 cases (39.3%) and affected the length of hospital stay only (11.6%) or the admission charge only (12.9%) more often than both (7.8%, p < 0.01) or neither (7.0%, p < 0.01). The most common variances in these patients were patient related (30.8%). CONCLUSIONS: Implementation of multiple clinical pathways in a urology department can improve urological practice by decreasing the length of hospital stay, admission charges and rate of surgical complications, and by improving the quality of care.

Improvements in the efficiency of care after implementing a clinical-care pathway for transurethral prostatectomy.

OBJECTIVE: To investigate the efficiency of care, length of hospital stay and admission charges after implementing a clinical-care pathway for transurethral prostatectomy (TURP). PATIENTS AND METHODS: Changes in the length of hospital stay and admission charges were identified by comparing a series of 100 patients undergoing TURP and treated after implementing a clinical-care pathway with 100 patients treated by the same physicians before implementation. RESULTS: After implementing the care pathway, the mean length of hospital stay and admission charges were significantly lower (P < 0.01). The shorter length of stay was caused by a significant reduction (P < 0.05) in patient-related psychological/social delay after implementation. The number of laboratory tests and use of pharmacological agents were also significantly lower (P < 0.001) after implementation, with the decreases in these last variables significantly greater (P < 0.001) among junior physicians. CONCLUSIONS: The advantages of the TURP clinical-care pathway were the shorter hospital stay, arising from reduced patient-related psychological or social delay, and reduced admission charges consequent on the decreased use of laboratory tests and drugs, particularly for patients treated by junior physicians. These results suggest that physicians are likely to modify their management methods to improve efficiency when a clinical path is implemented.

Neonatal neurological assessment of offspring in maternal phenylketonuria.

This study assesses the impact of prenatal and postnatal factors in maternal phenylketonuria (PKU). The Dubowitz Neurological Assessment of the Preterm and Full-term Newborn Infant was administered within the first 8 days of life to 56 offspring of women with PKU and 45 controls. Follow-up testing of the maternal PKU offspring at age 1 year consisted of the Bayley Scales of Infant Development and the Receptive-Expressive Emergent Language Scale (REEL). In addition, the Home Observation for Measurement of the Environment (HOME Scale) was given. Birth weight was lower (z = 2.0, p = 0.045), birth length was lower (z = 2.1, p = 0.03) and birth head circumference was smaller (z = 3.5, p = 0.0005) in the maternal PKU offspring than in the control infants. Examiners rated 29% of the maternal PKU offspring and 9% of the control infants abnormal (Fisher's exact test, p = 0.01). At 1 year of age, 19% of the maternal PKU offspring attained a Bayley Developmental Quotient (DQ) and a score on the Bayley Motor Scale below 85; 19% had receptive language delay; and 26% had expressive language delay. The gestational age at which the mother attained metabolic control was an important factor associated with birth measurements, the Dubowitz Rating and subsequent developmental scores. The Dubowitz Neurological Assessment score did not predict developmental outcome (chi-square = 1.3, p = 0.53), while the HOME score correlated with the DQ (r = 0.36, p = 0.02). In logistic regression analyses, the home environment was a greater determinant of risk for a low DQ than whether or not the mother attained metabolic control prior to pregnancy (OR = 0.85, p = 0.02). These results suggest that treatment strategies addressing both prenatal and postnatal factors will most effectively reduce risks in maternal PKU.

Onychomycosis in children: prevalence and management.

Onychomycosis in children is often accompanied by tinea pedis and a family history of onychomycosis. The prevalence of onychomycosis in children is substantially lower than that of adults; therefore it is important to confirm the clinical diagnosis. The most common presentation of onychomycosis is the distal and lateral subungual type. The organism most commonly isolated in North America is Trichophyton rubrum. Oral antifungal therapy is required, especially when the onychomycosis is of moderate to severe intensity, with nail matrix involvement. The new oral antifungal agents itraconazole, terbinafine, and fluconazole are being increasingly used for the treatment of onychomycosis. Review of the literature suggests that these agents are effective and safe in managing onychomycosis in children. The short duration of therapy required with these drugs should help improve compliance. The data suggest that the new oral antifungal agents have a role in the treatment of onychomycosis in children. Further experience will help us better position these drugs when evaluating the management of onychomycosis in children.
