Asymptomatic Infant Rib Fractures Are Primarily Non-abuse-Related and Should Not Be Used to Assess Physical Child Abuse.

Finding infant rib fractures was for many years an almost undisputed proof that physical child abuse took place. Yet, these rib fractures are virtually always occult and asymptomatic and are only identified when looked for, usually with X-rays, from physical child abuse accusations related to, e.g., suspicion of the shaken baby syndrome. In a recent systematic literature review (searched in Cochran, Embase, PubMed and Sociological Abstracts), Güvensel questioned the diagnostic accuracy of rib fractures to be caused by abuse, due to lack of sufficient scientific evidence. Further, there is currently a world-wide disagreement between physicians considering themselves child abuse specialized, and physicians that explore non-abuse-related symptoms that may mimic physical abuse, which, it is hoped, will significantly reduce current unjustified child abuse diagnoses. In an attempt to help resolving this disagreement, we hypothesize that the probability of physical child abuse-related infant rib fractures is significantly lower than the probability of all other possible non-abuse-related causes of occult asymptomatic infant rib fractures, e.g., from birth trauma, prematurity, osteogenesis imperfecta, hypermobile Ehlers-Danlos Syndrome, severe chronic placental pathology (e.g., massive perivillous fibrin depositions and severe chronic histiocytic intervillositis), and vitamin-D deficiency. As method, we attempted to assess the incidence of these various causes of infant rib fractures, in the Netherlands and the USA. The results are that the estimated Dutch and USA physical abuse-related infant rib fracture incidences are at least about 250 and 45 times lower than the sum of all the non-abuse-related estimates. Because these latter rib fractures are occult and asymptomatic, it is likely that (many) more could be out there. In conclusion, occult asymptomatic rib fractures develop perinatally, virtually always as birth trauma, in infants with sufficiently weak bones due to vitamin D deficiency, transmitted by their vitamin D deficient pregnant mothers. This group also includes cortical rib cracks due to deformation forces, with an estimated 186/100,000 incidence. And, despite obvious uncertainties in all estimated incidences, we provided strong evidence that our hypothesis has relevance, implying that the abundant occult asymptomatic rib fractures, when found in infants, should not be used to assess potential physical child abuse.

Child Abuse, Misdiagnosed by an Expertise Center: Part I-Medico-Social Aspects.

Child abuse is a dangerous situation for an infant. Professionals need to weigh the risk of failing to act when children are seriously harmed against the serious harm done by carrying out safeguarding interventions. In severe cases, foster care might be advisable. The negative effects for the child's psychosocial development requires that such placement must be based on very solid evidence. Our aim is to identify why Dutch parents whose child may have a medical condition that could mimic symptoms of child abuse have a significant chance of being erroneously convicted and losing custody of their child. As a method, we describe and analyze the following case. An Armenian-Dutch newborn (uncomplicated term vaginal delivery), starting at two weeks after birth, developed small bruises on varying body locations. At two months, a Well-Baby Clinic physician referred the girl to a university hospital, mentioning that there were no reasons to suspect child abuse and that her Armenian grandmother easily bruised as well. However, before consultation by a pediatrician of the hospital-located Expertise Center for Child Abuse, the parents were suspected of child abuse. Based on the expertise center's protocols, skeletal X-rays were made, which showed three healed, asymptomatic rib fractures, while invalid statistics suggested, incorrectly, a 10-100 times more likely non-accidental than accidental cause of the symptoms (discussed in Part II of this series). The expertise enter physician ignored any argument that could show parental innocence, including the positive parent-child relationship reported by the Well-Baby Clinic and the general practitioner. The girl and her older brother were placed in a family foster home and then in a secret home. The case radically resolved when a large bruise also developed there, and an independent tissue disease specialist diagnosed a hereditary connective tissue disorder in the mother, implying that the girl's bruises and rib fractures could well be disease-related. In conclusion, if child abuse is suspected, and foster care placement considered, the patient and the parents should be thoroughly investigated by an independent experienced pediatrician together with an experienced pediatric clinical psychologist or psychotherapist to produce an independent opinion. Children deserve this extra safeguard before being separated from their parents.

Child Abuse, Misdiagnosed by an Expertise Center-Part II-Misuse of Bayes' Theorem.

A newborn girl had, from two weeks on, small bruises on varying body locations, but not on her chest. Her Armenian grandmother easily bruised, too. Her mother was diagnosed with hypermobility-type Ehlers-Danlos-Syndrome (hEDS), an autosomal dominant connective tissue disorder, with a 50% inheritance probability. Referral to a University Medical Center located "Dutch Expertise Center for Child Abuse" resulted (prior to consultation) in physical abuse suspicion. Protocol-based skeletal X-rays showed three healed, asymptomatic rib fractures. A protocol-based Bayesian likelihood ratio guesstimation gave 10-100, erroneously used to suggest a 10-100 times likelier non-accidental-than-accidental cause. Foster care placement followed, even in a secret home, where she also bruised, suggesting hEDS inheritance. Correct non-accidental/accidental Bayes' probability of symptoms is (likelihood ratio) × (physical abuse incidence). From the literature, we derived an infant abuse incidence between about ≈0.0009 and ≈0.0026 and a likelihood ratio of <5 for bruises. For rib fractures, we used a zero likelihood ratio, arguing their cause was birth trauma from the extra delivery pressure on the chest, combined with fragile bones as the daughter of an hEDS-mother. We thus derived a negligible abuse/accidental probability between <5 × 0.0009 <0.005 and <5 × 0.0026 <0.013. The small abuse incidence implies that correctly using Bayes' theorem will also miss true infant physical abuse cases. Curiously, because likelihood ratios assess how more often symptoms develop if abuse did occur versus non-abuse, Bayes' theorem then implies a 100% infant abuse incidence (unwittingly) used by LECK. In conclusion, probabilities should never replace differential diagnostic procedures, the accepted medical method of care. Well-known from literature, supported by the present case, is that (child abuse pediatrics) physicians, child protection workers, and judges were unlikely to understand Bayesian statistics. Its use without statistics consultation should therefore not have occurred. Thus, Bayesian statistics, and certainly (misused) likelihood ratios, should never be applied in cases of physical child abuse suspicion. Finally, parental innocence follows from clarifying what could have caused the girl's bruises (inherited hEDS), and rib fractures (birth trauma from fragile bones).

A qualitative study on the patient's narrative in the progression of chronic venous disease into a first venous leg ulcer: a series of events.

BACKGROUND: A venous leg ulcer (VLU) has a significant negative impact on quality of life. Prevention of a VLU is not yet imbedded in clinical practice because risk factors for developing a first VLU are not well known. OBJECTIVES: To explore further the progression of chronic venous disease (CVD) into a first VLU from the patient's perspective. METHODS: A qualitative study using semistructured interviews was conducted among male and female patients with a VLU. Patients from primary and secondary care, under and over 50 years of age, and with first and recurrent VLUs were included. The interviews were transcribed and analysed using a narrative approach to a thematic analysis. Transcripts were organized in chronological order and an iterative process was used to code the transcripts. RESULTS: Four key themes and the connections made between them emerged from the 11 narratives on the progression of CVD towards a first VLU: 'comorbidity', 'mobility', 'work and lifestyle' and 'acknowledgment of CVD'. Comorbidity was linked to reduced mobility and late acknowledgment of CVD. Comorbidity also affected work and lifestyle and vice versa. Work and lifestyle affected mobility and was linked to the acknowledgment of CVD. CONCLUSIONS: A reduction in mobility as a result of comorbidity and work and lifestyle occurred before the VLU developed. Patients did not recognize symptoms of CVD and did not acknowledge the chronicity of CVD. Healthcare professionals should be aware of reductions in mobility and the knowledge deficit in patients with CVD. What's already known about this topic? Not all patients with chronic venous disease (CVD) develop a venous leg ulcer (VLU). A patient's quality of life decreases significantly when a VLU develops. Risk factors for the development of a first VLU in patients with CVD are not well known, unlike risk factors for other chronic wounds like diabetic foot ulcer and pressure ulcers. What does this study add? The patient's narrative towards the development of a first VLU, a series of events. Insight into the events (comorbidity, mobility, work and lifestyle) that patients themselves link to the development of a VLU. Insight into the patients' acknowledgment of CVD in the progression of CVD towards a first VLU. What are the clinical implications of this work? More awareness is needed of CVD symptoms among patients and healthcare providers, as well as more awareness for prevention of a VLU in clinical practice. New insights (for further studies) are needed into the concept of mobility and the development of a VLU. Improved patient education and follow-up are needed for patients with CVD.

A scoping review on Chronic Venous Disease and the development of a Venous Leg Ulcer: The role of obesity and mobility.

OBJECTIVE: The risk factors obesity and reduced mobility are not well known in the development of a Venous Leg Ulcer (VLU). The aim of this scoping review is to explore the mechanisms by which obesity and reduced mobility contribute the development of a VLU in patients with Chronic Venous Disease (CVD). METHODS: For this scoping review a search was performed in May 2019 in the Cochrane Library and Pubmed to identify studies on the working mechanisms of obesity and mobility in developing a VLU. Hand searches were performed to find additional studies explaining the working mechanisms (indirectly related to the VLU). Two reviewers independently reviewed the abstracts and full-text articles. RESULTS: Twenty-eight studies met our eligibility criteria. Disturbed range of ankle motion and gait can lead to a reduced Calf Muscle Pump (CMP) function which leading to a venous outflow disorder. Increased abdominal pressure due to obesity can lead to a venous outflow obstruction and increased adipose tissue mass results in an increase in adipokine secretion. The venous outflow disorder, outflow obstruction and increased adipokine secretion can all lead to chronic systemic inflammation, increased endothelial permeability and hence microcirculatory dysfunction. This alone can result in a VLU. CONCLUSION: Obesity and reduced mobility can lead to a reduction of the CMP function, an increase in abdominal pressure and an increase in adipose tissue mass. This can simultaneously lead to haemodynamic changes in the macro- and microcirculation of the lower extremities and eventually in a VLU. In patients with obesity and reduced mobility the microcirculation alone can lead to skin changes and eventually a VLU. Therefore, early recognition of CVD symptoms in patients with obesity and reduced mobility is crucial to diagnose and treat CVD to prevent a VLU.

Weight velocity equations with 14-448 days time separated weights should not be used for infants under 3 years of age.

Abnormal growth of infants may indicate disease of the children, thus methods to identify growth disorders are wanted in medicine. We previously showed that two-time-points weight growth velocities at age t, calculated by a commercial software product as [Weight(t) - Weight(t - X)]/X, with X = 448 days, were erroneous due to the long separation of 448 days. We were convinced that shorter X-values would solve this accuracy problem. However, our hypothesis is that: "shorter time separations than 448 days cause a decreased accuracy of numerical weight velocity equations in realistic infant weights until an age of about three years". Supporting evidence comes from analyzing how shorter X-values will affect the accuracy of two-time-points weight velocity calculations. We systematically varied X between 1 and 448 days of various P50/0SD-related standard weight curves: (a) P50/0SD with the weights separated by 1 day and X = 1,28,224,448 days; (b) P50/0SD with the weights at variable ages and X = 14-448 days; and (c) case (b) and incorporating weight fluctuations typically occurring in infants. Cases (b) and (c) include details observed in a clinical case. Our results show that the combination of weight fluctuations and varying time intervals between consecutive weights make weight velocity predictions worse for shorter X values in children younger than three years. Because these two causes of failure occur naturally in infants whose weight is regularly measured, other weight velocity equations face the same causes for inaccuracy. In conclusion, our hypothesis suggests that any software that predicts weight velocities should be abandoned in infants < 3 years. Practically, it should require that when (commercial) software weight velocity prediction suggests a medical problem, careful clinical checking should be mandatory, e.g. by linking predicted and exact weight velocities at age t (the latter from the mathematical first derivative at age t of standard weight curves).

A systematic review on risk factors in developing a first-time Venous Leg Ulcer.

Venous Leg Ulcers (VLU) occur in about 1% of the Western population. A VLU takes 3-12 months to heal, it recurs often, and it has a negative impact on the quality of life. The risk factors for the development of a first VLU are not well-understood and prevention of a first VLU therefore remains underappreciated. The aim of this study was to identify risk factors for developing a first VLU in adults (aged > 18 years) by searching the literature. We searched the Cochrane Library, Pubmed, Cinalh and Narcisto identify studies that investigated risk factors in developing a VLU. The last search was performed in January 2018. Two reviewers independently reviewed the abstracts and full-text articles, and assessed the methodological quality of the included studies. Results of studies using duplex scanning, and comparing participants with and without VLUs were included in the qualitative analysis. Where possible a quantitative meta-analysis was conducted. We found five studies that investigated the relation of several risk factors with VLU development. The methodological differences of the studies made it impossible to perform a quantitative analysis. The risk factors higher age (four studies), higher body mass index (four studies), low physical activity (four studies), arterial hypertension (four studies), deep vein reflux (three studies), deep venous thrombosis (three studies) and family history of VLU (three studies) were significantly associated with a VLU in the majority of the studies. To what extent they influence the development of a VLU remains unclear because of the limited number of studies that investigated the association of these risk factors with VLU development, and the heterogeneity of these studies. Further studies are needed to confirm the association of these risk factors with the development of a VLU and to explore overweight and low physical activity in more detail.

Limitations of Weight Velocity Analysis by Commercial Computer Program Growth Analyser Viewer Edition.

Commercial software package "Growth Analyser Viewer Edition" ("GAVE") aims to document, monitor and analyze growth and development in children and adolescents. Although its clinical and scientific use is widespread, there are no published studies that describe the method and its validation. We were informed that GAVE calculates the weight velocity (kg/year) at age t from the weight difference between t and 448 days earlier or at birth, divided by the time difference. We recently discussed a case of false child abuse diagnosis (Pediatric Condition Falsification), resulting in the separation of the child from its parents, in which GAVE played a negative contributing role. To prevent such inappropriate diagnoses, we analyzed GAVE from a schematic representation of the measured clinical weight curve, with precisely defined weight velocities. In conclusion, the 448 days included for weight velocity predictions by GAVE caused the erroneous outcomes. Until the necessary changes to the software are implemented and validated, we advise against the use of GAVE in infants younger than 1.5 years, if multiple weight changes occur within 448 days, and following a long-lasting weight velocity change. Our analysis suggests to discard all medical software packages that lack public description and proof of validation.

Periocular CO2 laser resurfacing: severe ocular complications from multiple unintentional laser impacts on the protective metal eye shields.

BACKGROUND AND OBJECTIVES: A 36-year-old woman underwent CO2 laser resurfacing for periocular rhytides using protective stainless steel Cox II ocular shields. Immediately after the treatment, corneal lesions were seen in both eyes. The left eye subsequent developed corneal ulceration and scarring, a deformed iris, cataract, and lower eye lashes showing signs of acute burns. The right cornea had a small inferior mid-peripheral superficial lesion and concomitant lower mid-peripheral burned eye lashes. Our objective was to determine the most likely cause of these ocular complications. STUDY: We estimated temperature-time combinations that could induce corneal injury and cataract. Heat conduction effects from a heated cornea to the lens and from a heated ring of periocular skin to the cornea were computed. The temperature response of a shield following CO2 laser irradiation was determined. RESULTS: We computed that cataract can develop when the corneal temperature reaches, for example, 80 °C for 14 seconds. A periocular ring of heated skin contributes little to the corneal temperature. After 7 pulses of consecutive CO2 laser bursts in 7.5 seconds, the total shield area already reached a homogeneous temperature of 63 °C. CONCLUSION: Despite uncertainties in procedural details and modeling of cataract temperatures, the eye injuries were caused beyond doubt by heating of tear-covered metal eye shields by at least 10 consecutive but unintentional laser impacts.

Pediatric Condition Falsification Misdiagnosed by Misjudged Weight Growth from the Curve of Measured Weights.

BACKGROUND Pediatric condition falsification (PCF) is a rare form of child abuse in which a caregiver fabricates or induces illness in the child. The diagnosis is difficult and controversial and can easily include false positives. CASE REPORT A boy, 3.18 kg birthweight (P25 curve), lost weight between age 56 to120 days. Cow milk allergy was suspected, feeding was changed to elementary formula, and he started catch-up weight growth while remaining significantly underweight. His pediatrician continuously interpreted his low weight as insufficient growth, despite prescribing 3 times the normal caloric intake, concluded that the mother purposely malnourished her son, diagnosed PCF, and the boy was separated from his family (days 502-755 of age). PCF was confirmed by 2 other pediatricians and 3 child protection physicians and was supported by 4 child protection agencies and 6 judges. However, proper analysis of the weight growth (kg/year) from the weight curve showed a normal weight gain. Beyond 120 days of age, weight gain at home was significantly above normal (during 347-489 days: 6.2 versus 3 kg/year of the P50). He reached P25 again at around 516 days. CONCLUSIONS The question "How could so many physicians misjudge weight gain?" has scientific and sociologic aspects. Scientifically, low weight was wrongly interpreted as insufficient weight growth, requiring that physicians learn how to assess weight gain from weight curves. Sociologically, physicians seem to follow a diagnosis made by a colleague without proper evaluation. Arguments provided by the parents against this diagnosis seemed to be neglected. Confirmation bias occurs when any information against PCF is disregarded.

Progressive multifocal leukoencephalopathy associated with fumaric acid esters treatment in psoriasis patients.

BACKGROUND: Fumaric acid esters (FAEs) are a systemic treatment for psoriasis considered to have a favourable long-term safety profile without an increased risk for immunosuppression. However, progressive multifocal leukoencephalopathy (PML), a rare, opportunistic viral infection of the central nervous system, has been linked anecdotally to FAE treatment. OBJECTIVE: To assess clinical features and outcomes of FAE-associated PML cases. METHODS: Systematic literature search in multiple databases up to 25th February 2016 for reports of PML in psoriasis patients treated with FAEs. RESULTS: Eight cases (four male, four female) of FAE-associated PML were identified. Median age was 64 years (range 42-74 years); median FAE treatment duration was 3 years (range 1.5-5 years). Six patients were treated with a formulation containing dimethyl fumarate (DMF) and monoethyl fumarates, and two patients with a DMF formulation. Patients exhibited neurological symptoms, such as aphasia, hemiparesis and dysarthria. PML diagnosis was based on MRI findings and presence of JC virus in cerebrospinal fluid and/or brain tissue. All cases were linked to moderate-to-severe reductions in absolute lymphocyte counts, with nadirs ranging from 200 to 792 cells per mm3 . Median exposure to lymphocytopenia was 2 years (range 1-5 years). In all cases, FAE treatment was discontinued; PML was treated with mefloquine plus mirtazapine. Three patients improved, two had stable disease, two had residual symptoms, and one patient died to an immune reconstitution inflammatory syndrome. CONCLUSION: Progressive multifocal leukoencephalopathy is infrequently linked to FAE treatment, but underreporting cannot be excluded. Physicians treating patients with FAEs should be vigilant for the occurrence of PML, and both clinicians and patients should be alert for onset of new neurological symptoms. Periodic monitoring of lymphocyte counts and FAE discontinuation in case of moderate-to-severe lymphocytopenia is recommended to minimize the risk for PML.

Reliability of diagnosis from Mohs slides: interpersonal and intrapersonal agreement on basal cell carcinoma presence and histological subtype.

BACKGROUND: The success of Mohs micrographic surgery (MMS) depends partly on the correct diagnosis of slides. OBJECTIVES: To determine reliability of diagnosis from Mohs slides. METHODS: This was a prospective study evaluating the reliability of diagnosis from Mohs slides of basal cell carcinoma (BCC) presence, BCC location on the slide and BCC subtype among six raters who independently assessed 50 Mohs slides twice with a 2-month interval. Slides were randomly selected whereby difficult-to-diagnose slides were oversampled. For each slide, a reference diagnosis was established by an expert panel. Cohen's kappa (κ) was calculated to determine levels of agreement interpersonally (rater vs. reference diagnosis) and intrapersonally (rater at T1 vs. T2). Multivariable logistic regression was used to determine independent risk factors for slides with interpersonal discordant diagnosis. The variables studied were BCC presence, whether a slide was scored as easy or difficult to diagnose, review duration of the 50 slides, profession and years of experience in diagnosis from Mohs slides. RESULTS: Interpersonal and intrapersonal agreement were substantial on BCC presence (κ = 0·66 and 0·68) and moderate on BCC subtype (κ = 0·45 and 0·55). Slides that were scored as difficult to diagnose were an independent risk factor for interpersonal discordant diagnosis on BCC presence (odds ratio 3·54, 95% confidence interval 1·81-6·84). CONCLUSIONS: Reliability of diagnosis from Mohs slides was substantial on BCC presence and moderate on BCC subtype. For slides that are scored difficult to diagnose, a second opinion is recommended to prevent misinterpretation and thereby recurrence of skin cancer.

Efficacy, effectiveness and safety of fumaric acid esters in the treatment of psoriasis: a systematic review of randomized and observational studies.

Fumaric acid esters (FAEs) are increasingly used as a systemic treatment for psoriasis, but there are still uncertainties regarding their suitability. The objective of this systematic review was to assess the evidence for the efficacy and safety of FAEs in psoriasis treatment. A systematic literature search was performed in seven databases up to 17 August 2015. Inclusion criteria were studies that reported clinical effects of FAEs in patients with psoriasis without restrictions in study design, language or publication date. Methodological quality of randomized controlled trials (RCTs) and overall level of quality were assessed using the Cochrane risk of bias tool and the Grading of Recommendation, Assessment, Development and Evaluation approach, respectively. A total of 68 articles were included. There were seven RCTs (total 449 patients) that had an unclear risk of bias and were too clinically heterogeneous to allow a meta-analysis. Overall, mean Psoriasis Area and Severity Index decreased by 42-65% following 12-16 weeks of treatment. There were 37 observational studies (a total of 3457 patients) that supported the RCT findings, but most were uncontrolled with a high risk of bias. Commonly reported adverse events included gastrointestinal complaints and flushing, leading to treatment withdrawal in 6-40% of patients. Several case-reports described rare adverse events, such as renal Fanconi syndrome and progressive multifocal leukoencephalopathy. There was a lack of studies focusing on long-term use and comparisons with other treatments. This review concluded that there is low-quality evidence to recommend the use of oral FAEs to treat plaque psoriasis in adult patients. Studies focusing on long-term safety and comparison with systemic psoriasis treatments could lead to a better understanding of the role of FAEs as a treatment for psoriasis.

Validation of the Lymphoedema Quality-of-Life Questionnaire (LYMQOL) in Dutch Patients Diagnosed with Lymphoedema of the Lower Limbs.

BACKGROUND: The Lymphoedema Quality-of-Life Questionnaire is a validated disease-specific instrument to measure the impact of lymphoedema on patients' lives. In this study, we tested its psychometric properties and validated the use of the questionnaire in its Dutch translation. METHODS: We obtained the answers to a standardised questionnaire, including Lymphoedema Quality-of-Life Questionnaire and Short-Form (36) Health Survey, twice at an interval of 2 weeks in 60 patients with lower limb lymphoedema. Feasibility was tested on the basis of missing responses and response distribution. Structure was studied using factor analysis. The reliability of the Lymphoedema Quality-of-Life Questionnaire was assessed using Crohnbach's α and test-retest reliability. Construct validity was tested by correlating Lymphoedema Quality-of-Life Questionnaire scores with the Short-Form (36) Health Survey scores. RESULTS: The response rate was 88.2%. One of the 22 items missed >10% of responses; another showed a borderline ceiling effect. Internal consistency was good and test-retest reliability was excellent. The Lymphoedema Quality-of-Life Questionnaire correlated well with the physical component of the Short-Form (36) Health Survey and moderately with the mental component, suggesting that its construct validity was good. CONCLUSION: The Dutch Lymphoedema Quality-of-Life Questionnaire can be used for health-related quality-of-life research in lower limb lymphoedema patients.

Induction therapy with a combination of fumarates and cyclosporine: A benefit for the patient?

Fumarates or fumaric acid esters derivates (FAED) have appeared to be effective and less toxic than other systemic treatments for psoriasis. Due to its safe adverse event profile, FAED can be used as a long-term maintenance therapy. One of the greatest reasons why FAED are not preferred as a first-line treatment is that according to the recommended dosing schedule, clinically meaningful improvement is seen just after 6 to 8 weeks of therapy. In this manuscript, we suppose an alternative induction scheme with a combination therapy of fumarates and cyclosporine for a more rapid improvement and better compliance.

Advances in hair transplantation: longitudinal partial follicular unit transplantation.

There are different techniques of hair transplantation. The most common and known hair transplantation methods are the 'strip' method, where a strip of skin containing hair follicles is removed, cut into grafts and implanted in the recipient area, and the follicle unit extraction (FUE) method, in which whole follicle units are extracted one by one and implanted one by one back into the recipient area. The FUE method is more patient friendly and leaves only tiny scars compared to the strip method, which leaves visible linear scars at the donor area. Both methods, however, have the major disadvantage that the extracted hair follicles are removed and the availability of donor hair follicles are limited and results in a decrease in hair density, as no re-grow will occur in the donor area. Since partial longitudinal-follicular unit transplantation (PL-FUT) extracts partial longitudinal follicular units that can be used as complete follicular units to regenerate completely differentiated hair growth and the partial follicular units that remain in the dermis in the donor area can survive and produce hair, PL-FUT enables us to multiply hair follicles in vivo while preserving the donor area. Although this technique is suitable for androgenic alopecia, PL-FUT could also be suitable in persons who have a relative small donor area compared to the recipient area like burn victims, as well as scarring alopecia's like frontal fibrosing alopecia.

Development of consensus International Classification of Functioning, Disability and Health (ICF) core sets for lymphedema.

To understand the challenges of patients with lymphedema it is important to describe functioning and to measure the effectiveness of treatment in changing functioning. The International Classification of Functioning, Disability and Health (ICF) offers an international framework to classify functioning of persons in their personal environment. ICF Core Sets are lists of selected ICF categories concerning those important aspects of functioning that are most likely to be affected by a specific health problem or disease. These Core Sets make it easier and faster to describe and communicate the patient's problems and to define treatment goals. Furthermore, they are available to health care providers of all professions, researchers, health insurance companies and policy-makers. The objective of this document is to present the outcomes of a consensus conference held to determine the first versions of the ICF Core Sets for lymphedema. Frequency rankings were made of the ICF categories derived from four preparatory studies, being: a) a systematic review; b) a qualitative study; c) an expert survey; and d) a cross-sectional study. By means of working group discussions and plenary sessions, a final consensus on ICF categories was achieved and Comprehensive and Brief Core Sets for lymphedema for the upper limb, lower limb, and midline lymphedema were defined. These ICF Core Sets contain different items in each region. Future validation of these Core Sets for health professions and for countries is needed.

Five-year results of a randomized clinical trial of conventional surgery, endovenous laser ablation and ultrasound-guided foam sclerotherapy in patients with great saphenous varicose veins.

BACKGROUND: A variety of techniques exist for the treatment of patients with great saphenous vein (GSV) varicosities. Few data exist on the long-term outcomes of these interventions. METHODS: Patients undergoing conventional surgery, endovenous laser ablation (EVLA) and ultrasound-guided foam sclerotherapy (UGFS) for GSV varicose veins were followed up for 5 years. Primary outcome was obliteration or absence of the treated GSV segment; secondary outcomes were absence of GSV reflux, and change in Chronic Venous Insufficiency quality-of-life Questionnaire (CIVIQ) and EuroQol - 5D (EQ-5D™) scores. RESULTS: A total of 224 legs were included (69 conventional surgery, 78 EVLA, 77 UGFS), 193 (86.2 per cent) of which were evaluated at final follow-up. At 5 years, Kaplan-Meier estimates of obliteration or absence of the GSV were 85 (95 per cent c.i. 75 to 92), 77 (66 to 86) and 23 (14 to 33) per cent in the conventional surgery, EVLA and UGFS groups respectively. Absence of above-knee GSV reflux was found in 85 (73 to 92), 82 (72 to 90) and 41 (30 to 53) per cent respectively. CIVIQ scores deteriorated over time in patients in the UGFS group (0.98 increase per year, 95 per cent c.i. 0.16 to 1.79), and were significantly worse than those in the EVLA group (-0.44 decrease per year, 95 per cent c.i. -1.22 to 0.35) (P = 0.013). CIVIQ scores for the conventional surgery group did not differ from those in the EVLA and UGFS groups (0.44 increase per year, 95 per cent c.i. -0.41 to 1.29). EQ-5D™ scores improved equally in all groups. CONCLUSION: EVLA and conventional surgery were more effective than UGFS in obliterating the GSV 5 years after intervention. UGFS was associated with substantial rates of GSV reflux and inferior CIVIQ scores compared with EVLA and conventional surgery. REGISTRATION NUMBER: NCT00529672 (http://www.clinicaltrials.gov).
