ABSTRACT
BACKGROUND: Several patient-reported outcome measures (PROMs) have been developed for research to assess the multiple dimensions of chronic pruritus (CP). The acceptability and perceived benefits of their use in clinical practice remain unknown. OBJECTIVES: To assess the acceptability and perceived benefits of validated PROMs from the perspective of patients and physicians in dermatological offices and clinics. METHODS: Patients with CP due to atopic dermatitis, psoriasis, chronic prurigo or chronic urticaria were recruited at 10 dermatological offices and two dermatological clinics in Germany. Patients completed a set of validated PROMs on pruritus intensity (numerical rating scale, NRS), symptom control (itch-controlled days, ItchCD), quality of life (Dermatology Life Quality Index, DLQI; 5-pruritus life quality, 5PLQ) and general health status (EuroQol, EQ-VAS). Acceptability (relevance, difficulty of completion, length) and benefits (usefulness, feasibility) of these tools were assessed on a NRS (0-10) by patients and physicians, respectively. Data were analysed descriptively. Linear regression was used to study potential associations between age, sex, occupation, office versus clinic, change of therapy and physician-reported benefits. RESULTS: N = 523 patients (46% male, average age: 53.5 years) participated. Acceptability of PROMs by patients was high, indicated by low difficulty (Md = 0, IQR = 0-1 for all PROMs) and high relevance (Md = 8, IQR = 4-10 for all PROMs). Also, most patients (89-95%) rated length of the questionnaires as 'exactly right'. Physicians rated the NRS as the most beneficial instrument (feasibility: Md = 8, IQR = 6-10; usefulness: Md = 9, IQR = 7-10). Hierarchical linear regression revealed that only recruitment site (dermatological office vs. clinic) was significantly associated with usefulness and feasibility (higher ratings for clinical context; ßs = 0.149-0.258, ps <0.05; except feasibility for EQ5d, ß = ns). CONCLUSION: PROMs are welcomed by patients, while physicians consider instruments measuring pruritus intensity and impairment of quality of life as beneficial for the clinical routine. Widespread implementation of PROMs in daily clinical work is needed to improve care.
ABSTRACT
BACKGROUND: The SARS-CoV-2 virus and its long-term consequences in adolescents have a global impact on upcoming medical issues. The aim of this study was to investigate the effects of a SARS-CoV-2 infection on cardiorespiratory parameters in young athletes. METHODS: In a cohort study involving repeated measurements during a six-month period, cardiorespiratory parameters were assessed in infected (SCoV) and non-infected (noSCoV) athletes. We evaluated handball players (17.2 ± 1.0 years) via performance diagnostics and a specific examination after a SARS-CoV-2 infection or without. RESULTS: We observed no significant differences between the two groups at the first visit. But between the first and second visit, the SCoV group's maximum power output was significantly lower than the noSCoV group's (- 48.3 ± 12.5; p ≤ 0.01 vs. - 15.0 ± 26.0 W; p = 0.09). At the second visit, lung diffusion capacity (DLCO/VA, %predicted) did not differ between groups (111.6 ± 11.5 vs. 116.1 ± 11.8%; p = 0.45). HR during comparative stress showed no group differences. The SCoV group's mean oxygen uptake during incremental exercise was lower (Two-way-ANOVA: 1912 vs. 2106 ml; p ≤ 0.01; mean difference: - 194 ml; 95% CI - 317 to - 71); we also noted a significantly lower stroke volume course during exercise (Two-way-ANAOVA: 147.5 vs. 169.5 ml; mean difference: - 22 ml; p ≤ 0.01; 95% CI - 34.2 to - 9.9). The probability of premature ventricular complexes after a SARS-CoV-2 infection yielded an odds ratio of 1.6 (95% CI 0.24-10.81). CONCLUSIONS: The physical performance of young athletes infected with SARS-CoV-2 was impaired. This decreased performance is probably due to cardiac and/or peripheral deconditioning. Studies with larger cohorts are needed to make more profound conclusions.
ABSTRACT
We present results from an analysis of all data taken by the BICEP2, Keck Array, and BICEP3 CMB polarization experiments up to and including the 2018 observing season. We add additional Keck Array observations at 220 GHz and BICEP3 observations at 95 GHz to the previous 95/150/220 GHz dataset. The Q/U maps now reach depths of 2.8, 2.8, and 8.8 µK_{CMB} arcmin at 95, 150, and 220 GHz, respectively, over an effective area of ≈600 square degrees at 95 GHz and ≈400 square degrees at 150 and 220 GHz. The 220 GHz maps now achieve a signal-to-noise ratio on polarized dust emission exceeding that of Planck at 353 GHz. We take auto- and cross-spectra between these maps and publicly available WMAP and Planck maps at frequencies from 23 to 353 GHz and evaluate the joint likelihood of the spectra versus a multicomponent model of lensed ΛCDM+r+dust+synchrotron+noise. The foreground model has seven parameters, and no longer requires a prior on the frequency spectral index of the dust emission taken from measurements on other regions of the sky. This model is an adequate description of the data at the current noise levels. The likelihood analysis yields the constraint r_{0.05}<0.036 at 95% confidence. Running maximum likelihood search on simulations we obtain unbiased results and find that σ(r)=0.009. These are the strongest constraints to date on primordial gravitational waves.
ABSTRACT
PURPOSE: This study evaluates the capacity of ultrasonography as a diagnostic method to confirm the proper positioning of central venous catheter (CVC) when compared to the current gold standard, chest radiography (CR). METHODS: A prospective study was performed including children from 0 to 14 incomplete years, who underwent CVC placement between March and May 2018 at a teaching hospital in Brazil. A four-chamber view of the heart was performed with ultrasound during a rapid injection of saline solution to identify hyperechoic images and confirm the central position of the catheter. After that, a CR was performed. The diagnostic quality of ultrasound was evaluated based on accuracy, sensitivity, specificity, positive and negative predictive values. RESULTS: A total of 21 patients were analyzed. The mean age was 3.95 ± 4.01 years. The preferred puncture site was the right internal jugular vein (71.4%). Ultrasound accuracy to detect CVC positioning was 81%. Sensitivity, specificity and positive and negative predictive values were 33%, 100%, 100% and 79%, respectively. CONCLUSION: Ultrasound is a reliable method for detection of CVC positioning. Even so, with the four-chamber cardiac view, this method is unable to identify catheters inside heart chambers, therefore, needing to confirm the positioning with CR.

We present results from an analysis of all data taken by the bicep2/Keck CMB polarization experiments up to and including the 2015 observing season. This includes the first Keck Array observations at 220 GHz and additional observations at 95 and 150 GHz. The Q and U maps reach depths of 5.2, 2.9, and 26 µK_{CMB} arcmin at 95, 150, and 220 GHz, respectively, over an effective area of ≈400 square degrees. The 220 GHz maps achieve a signal to noise on polarized dust emission approximately equal to that of Planck at 353 GHz. We take auto and cross spectra between these maps and publicly available WMAP and Planck maps at frequencies from 23 to 353 GHz. We evaluate the joint likelihood of the spectra versus a multicomponent model of lensed-ΛCDM+r+dust+synchrotron+noise. The foreground model has seven parameters, and we impose priors on some of these using external information from Planck and WMAP derived from larger regions of sky. The model is shown to be an adequate description of the data at the current noise levels. The likelihood analysis yields the constraint r_{0.05}<0.07 at 95% confidence, which tightens to r_{0.05}<0.06 in conjunction with Planck temperature measurements and other data. The lensing signal is detected at 8.8σ significance. Running a maximum likelihood search on simulations we obtain unbiased results and find that σ(r)=0.020. These are the strongest constraints to date on primordial gravitational waves.
ABSTRACT
We present results from an analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season. This includes the first Keck Array observations at 95 GHz. The maps reach a depth of 50 nK deg in Stokes Q and U in the 150 GHz band and 127 nK deg in the 95 GHz band. We take auto- and cross-spectra between these maps and publicly available maps from WMAP and Planck at frequencies from 23 to 353 GHz. An excess over lensed ΛCDM is detected at modest significance in the 95×150 BB spectrum, and is consistent with the dust contribution expected from our previous work. No significant evidence for synchrotron emission is found in spectra such as 23×95, or for correlation between the dust and synchrotron sky patterns in spectra such as 23×353. We take the likelihood of all the spectra for a multicomponent model including lensed ΛCDM, dust, synchrotron, and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r) using priors on the frequency spectral behaviors of dust and synchrotron emission from previous analyses of WMAP and Planck data in other regions of the sky. This analysis yields an upper limit r_{0.05}<0.09 at 95% confidence, which is robust to variations explored in analysis and priors. Combining these B-mode results with the (more model-dependent) constraints from Planck analysis of CMB temperature plus baryon acoustic oscillations and other data yields a combined limit r_{0.05}<0.07 at 95% confidence. These are the strongest constraints to date on inflationary gravitational waves.
ABSTRACT
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg^{2} patch of sky centered on RA 0 h, Dec. -57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven frequencies from 30 to 353 GHz, but much less deeply in any given region (1.2 µK deg in Q and U at 143 GHz). We detect 150×353 cross-correlation in B modes at high significance. We fit the single- and cross-frequency power spectra at frequencies ≥150 GHz to a lensed-ΛCDM model that includes dust and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r), using a prior on the frequency spectral behavior of polarized dust emission from previous Planck analysis of other regions of the sky. We find strong evidence for dust and no statistically significant evidence for tensor modes. We probe various model variations and extensions, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint. Finally, we present an alternative analysis which is similar to a map-based cleaning of the dust contribution, and show that this gives similar constraints. The final result is expressed as a likelihood curve for r, and yields an upper limit r_{0.05}<0.12 at 95% confidence. Marginalizing over dust and r, lensing B modes are detected at 7.0σ significance.
ABSTRACT
We report results from the BICEP2 experiment, a cosmic microwave background (CMB) polarimeter specifically designed to search for the signal of inflationary gravitational waves in the B-mode power spectrum around ââ¼80. The telescope comprised a 26 cm aperture all-cold refracting optical system equipped with a focal plane of 512 antenna coupled transition edge sensor 150 GHz bolometers each with temperature sensitivity of ≈300 µK(CMB)âs. BICEP2 observed from the South Pole for three seasons from 2010 to 2012. A low-foreground region of sky with an effective area of 380 square deg was observed to a depth of 87 nK deg in Stokes Q and U. In this paper we describe the observations, data reduction, maps, simulations, and results. We find an excess of B-mode power over the base lensed-ΛCDM expectation in the range 30 < â < 150, inconsistent with the null hypothesis at a significance of >5σ. Through jackknife tests and simulations based on detailed calibration measurements we show that systematic contamination is much smaller than the observed excess. Cross correlating against WMAP 23 GHz maps we find that Galactic synchrotron makes a negligible contribution to the observed signal. We also examine a number of available models of polarized dust emission and find that at their default parameter values they predict power â¼(5-10)× smaller than the observed excess signal (with no significant cross-correlation with our maps). However, these models are not sufficiently constrained by external public data to exclude the possibility of dust emission bright enough to explain the entire excess signal. Cross correlating BICEP2 against 100 GHz maps from the BICEP1 experiment, the excess signal is confirmed with 3σ significance and its spectral index is found to be consistent with that of the CMB, disfavoring dust at 1.7σ. The observed B-mode power spectrum is well fit by a lensed-ΛCDM+tensor theoretical model with tensor-to-scalar ratio r = 0.20_(-0.05)(+0.07), with r = 0 disfavored at 7.0σ. Accounting for the contribution of foreground, dust will shift this value downward by an amount which will be better constrained with upcoming data sets.
ABSTRACT
A new S2k AWMF guideline for the treatment of idiopathic facial palsy has been published. An accurate differential diagnosis is indispensable as 25-40% of all facial palsy cases are of non-idiopathic origin. It is explicitly recommended to treat patients with idiopathic facial palsy with steroids. Steroids favour a complete recovery, decrease the risk of synkinesis, autonomic sequelae and contractures. Adjuvant antiviral therapy cannot be recommended. On current data there is not sufficient evidence that the combination of steroids with antiviral drugs has a benefit for the patients. Even when not supported by randomized trials, adjuvant symptomatic therapy to protect the cornea and to avoid complications is recommended. There is no scientific evidence that physical therapy has any benefit but it should be taken into account because of psychological reasons. A benefit of acupuncture has not been proven. If eye closure remains incomplete as result of defective healing, one therapeutic option is lid loading of the upper eye lid. Moreover, in case of severe persistent palsy, several well-established microsurgical nerve and muscle plasty procedures are available.

Previously observed non-Arrhenius behavior in fast ion conducting glasses [J. Kincs and S. W. Martin, Phys. Rev. Lett. 76, 70 (1996)] occurs at temperatures near the glass transition temperature, T(g), and is attributed to changes in the ion mobility due to ion trapping mechanisms that diminish the conductivity and result in a decreasing conductivity with increasing temperature. It is intuitive that disorder in glass will also result in a distribution of the activation energies (DAE) for ion conduction, which should increase the conductivity with increasing temperature, yet this has not been identified in the literature. In this Letter, a series of high precision ionic conductivity measurements are reported for 0.5Na(2)S + 0.5[xGeS(2) + (1-x)PS(5/2)] glasses with compositions ranging from 0 ≤ x ≤ 1. The impact of the cation site disorder on the activation energy is identified and explained using a DAE model. The absence of the non-Arrhenius behavior in other glasses is explained and it is predicted which glasses are expected to accentuate the DAE effect on the ionic conductivity.
ABSTRACT
Cubital tunnel syndrome (CuTS) is the second most common peripheral nerve compression syndrome. In German-speaking countries, cubital tunnel syndrome is often referred to as sulcus ulnaris syndrome (retrocondylar groove syndrome). This term is anatomically incorrect, since the site of compression comprises not only the retrocondylar groove but the cubital tunnel, which consists of 3 parts: the retrocondylar groove, partially covered by the cubital tunnel retinaculum (lig. arcuatum or Osborne ligament), the humeroulnar arcade, and the deep flexor/pronator aponeurosis. According to Sunderland , cubital tunnel syndrome can be differentiated into a primary form (including anterior subluxation of the ulnar nerve and compression secondary to the presence of an anconeus epitrochlearis muscle) and a secondary form caused by deformation or other processes of the elbow joint. The clinical diagnosis is usually confirmed by nerve conduction studies. Recently, the use of ultrasound and MRI have become useful diagnostic tools by showing morphological changes in the nerve within the cubital tunnel. A differential diagnosis is essential in atypical cases, and should include such conditions as C8 radiculopathy, Pancoast tumor, and pressure palsy. Conservative treatment (avoiding exposure to external noxes and applying of night splints) may be considered in the early stages of cubital tunnel syndrome. When nonoperative treatment fails, or in patients who present with more advanced clinical findings, such as motor weakness, muscle atrophy, or fixed sensory changes, surgical treatment should be recommended. According to actual randomized controlled studies, the treatment of choice in primary cubital tunnel syndrome is simple in situ decompression, which has to be extended at least 5-6 cm distal to the medial epicondyle and can be performed by an open or endoscopic technique, both under local anesthesia. Simple decompression is also the therapy of choice in uncomplicated ulnar luxation and in most post-traumatic cases and other secondary forms. When the luxation is painful, or when the ulnar nerve actually "snaps" back and forth over the medial epicondyle of the humerus, subcutaneous anterior transposition may be performed. In cases of severe bone or tissue changes of the elbow (especially with cubitus valgus), the anterior transposition of the ulnar nerve may again be indicated. In cases of scarring, submuscular transposition may be preferred as it provides a healthy vascular bed for the nerve as well as soft tissue protection. Risks resulting from transposition include compromise in blood flow to the nerve as well as kinking of the nerve caused by insufficient proximal or distal mobilization. In these cases, revision surgery is necessary. Epicondylectomy is not common, at least in Germany. Recurrence of compression on the ulnar nerve at the elbow may occur. This review is based on the German Guideline "Diagnose und Therapie des Kubitaltunnelsyndroms" ( www.leitlinien.net ).

The cubital tunnel syndrome is one of the most widespread compression syndromes of a peripheral nerve. In German-speaking countries it is known as the sulcus ulnaris syndrome (retrocondylar groove syndrome), which is anatomically incorrect. The cubital tunnel consists of the retrocondylar groove, the cubital tunnel retinaculum (Lig. arcuatum or Osborne band), the humeroulnar arcade and the deep flexor/pronator aponeurosis. According to Sunderland it can be divided into a primary form (including the ulnar luxation and the epitrocheoanconaeus muscle) and a secondary form caused by deformation or other processes of the elbow joint. The diagnosis has to be confirmed by a thorough clinical examination and nerve conduction studies. Neurosonography and MRI are becoming more and more important with improving resolution and enable the direct identification of morphological changes. Differential diagnosis is essential in atypical cases, especially C8 syndrome and pressure palsy. Double crush (double compression syndrome) may occur. Operative treatment is more effective than conservative treatment, which consists primarily of the prevention of exposure to external noxes. According to actual randomised controlled studies the therapy of choice of the primary form in most cases is the simple in situ decompression of the ulnar nerve in the cubital tunnel. This has to be extended at least up to 5-6 cm distally of the medial epicondyle and can be performed in the open or endoscopic technique, both under local anesthesia. Simple decompression is also the therapy of choice in uncomplicated ulnar luxation and in most post-traumatic cases and other secondary forms. In cases of severe bony or tissue changes of the elbow (especially cubitus valgus) the volar transposition of the ulnar nerve may be indicated. This can be performed in a subcutaneous or submuscular technique. Risks of transposition are impairment of perfusion and, above all, kinking caused by insufficient proximal or distal mobilisation of the nerve has to be avoided. In these cases revision surgery is necessary. The epicondylectomy is not common in our country. Recurrences may occur.

OBJECTIVE: Patients with chronic pain disorder are generally thought to be difficult to treat in psychosomatic rehabilitation. On average, their disorders tend to take a more chronic course than those of other patients, and they develop a higher rate of additional socio-medical problems, all of which increase the probability of therapy failure. Most of the time, such failures are attributed solely to the desire for early retirement and disability pensions, that is, a characteristic of the patient. However, a lack of specific therapeutic offers for patients with predominant psycho-social problems has also to be considered. The project described was designed to evaluate a newly developed socio-medical therapy module. This module aimed at bringing more transparency to the process of assessing occupational capabilities and work performance, thus improving the patients' motivation to participate in the rehabilitation program as well as the overall therapy outcome. METHODS: The project was implemented as a controlled, prospective evaluation study. A quasi-experimental 3-factorial design was employed, including two group factors (factor 1: socio-medical intervention [EG 1] vs. relaxation therapy module [EG 2]; factor 2: current application for premature pension vs. none; factor 3: repeated measurements [admission to inpatient therapy, discharge from the clinic, 6-months follow-up]). The treatment conditions for the experimental groups were realized according to an ABBA-scheme. Patients in both treatment conditions took part in pain disorder-specific coping groups and were also included in the regular inpatient treatment. At all three points of measurement, socio-demographic, socio-medical, symptomatic and motivational patient characteristics were obtained as dependent variables by use of well-established standardized patient surveys. In total, 206 patients suffering from a chronic pain disorder took part in the study (n [EG1]=100; n [EG2]=106). Both treatment groups were considered equal regarding relevant sample characteristics. RESULTS: The socio-medical intervention was equally well accepted by all patients. Patients of the first experimental group turned out to be better informed about socio-medical issues than members of the second experimental group. The rehabilitation treatment program as a whole was--independently of treatment group affiliation--highly effective. Despite contrary expectations, the socio-medical intervention did not have an additional (differential) therapeutic effect on the patients at all points of measurement, not even on those participants currently applying for retirement pensions. Also, there were no significant differences between the treatment groups regarding the days of sick leave within six months after discharge from inpatient rehabilitation. CONCLUSIONS: The original and possibly too ambitious goal of the project, namely to increase the rehabilitation success for patients with pain disorder and current pension applications by means of the therapeutic module labeled "social medicine", was not achieved. Nevertheless it is to be noted that this module was well received by the patients. Moreover, the authors consider it to be of high value in itself that this therapeutic module helps patients to become better informed.

Evidence-based supradisciplinary guideline that deals with the epidemiology, pathogenesis, symptoms, clinical and electrophysiological diagnosis, supplementary imaging investigations, differential diagnosis, conservative and surgical treatments, prognosis and course along with complications and revision surgery. The recommendations on investigation and treatment are based on a comprehensive literature search with critical evaluation and two consensus methods (expert group and Delphi technique) within the participating specialist societies. Besides this long version, a short version and a patient version can be viewed through the AWMF platform. The development of the guideline and the methodological foundations are documented in a method report. MAIN STATEMENTS: Apart from an accurate history and clinical neurological examination (including clinical tests), electrophysiological investigations (distal motor latency and sensory neurography) are particularly important. Radiography, MRI, high-resolution ultrasonography can be regarded as optional supplementary investigations. Among conservative treatment methods, treatment with a nocturnal splint and local infiltration of a corticosteroid preparation are effective. Oral steroids, splinting and ultrasound showed only short-term benefit. Surgical treatment is clearly superior to all other methods. Open and endoscopic procedures (when the endoscopic surgeon has sufficient experience) are equivalent. A routine epineurotomy and interfascicular neurolysis cannot be recommended. Early functional treatment postoperatively is important.

OBJECTIVE: After discharge from inpatient psychosomatic rehabilitation patients often face problems to transfer and stabilize the modifications they have achieved in the clinic. Using targeted outpatient aftercare interventions up to eight weeks after discharge from the inpatient programme we tried to support this transfer, thus enhancing treatment effectiveness. METHOD: The evaluation was carried out as a field experiment. Patients were matched into pairs and then allocated randomly to either a control or an experimental condition. The experimental group, which had participated in specific aftercare measures after inpatient therapy, was compared to the control group at "discharge from clinic" and "twelve weeks post-discharge" relative to a number of variables relevant in therapy outcome. RESULTS: Twelve weeks post-discharge patients who had participated in aftercare measures show significantly better progress relative to their physical and psychological complaints than patients in the control group. Also, they are more capable of coping with psychosocial demands of their everyday life. They experience better control of their symptoms and they are more successful in attaining the goals they have set for themselves for the time after discharge. CONCLUSIONS: The findings show that supplementing psychosomatic inpatient rehabilitation with specific aftercare measures will lead to better transfer and to increased effectiveness of psychosomatic rehabilitation. Also on account of our results, outpatient rehab aftercare programmes have in the meantime become a regular component of inpatient psychosomatic rehabilitation in Germany.

OBJECTIVE: Psychotherapists are considered to be sceptical of empirical measures of quality assurance. It is generally recognised that the success of these measures mainly depends on how they are accepted by the people involved. METHODS: The acceptance of a quality monitoring system among psychotherapists was investigated with a standardised assessment instrument. RESULTS: Practical relevance and practicability of the system were judged positively on the following dimensions: "support of clinical diagnostics", "examination of the outcome", "reflecting on the therapeutic process", "documentation", "integration in the therapeutic process", "pressure to succeed and control" and "work loading". The factors "professional experience", "profession" and "sex" had just a small influence on the degree of acceptance of the quality monitoring system. CONCLUSIONS: Psychotherapists consider a practically relevant and economical quality monitoring system as useful.

High concentrations of butyryl/isobutyrylcarnitine (C(4)-carnitine) in plasma with increase of ethylmalonic acid (EMA) in urine point to different genetic entities, and further investigations are required to differentiate the possible underlying defect. Here we report three unrelated cases, two neurologically affected and one asymptomatic, with this abnormal metabolite pattern due either to mutations in the ETHE1 gene or to a short-chain acyl-CoA dehydrogenase (SCAD) defect.

General mitochondrial trifunctional protein (TFP) deficiency leads to a wide clinical spectrum of disease ranging from severe neonatal/infantile cardiomyopathy and early death to mild chronic progressive sensorimotor poly-neuropathy with episodic rhabdomyolysis. Isolated long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency resulting from the common Glu510Gln mutation usually gives rise to a moderately severe phenotype with multiorgan involvement with high morbidity and mortality. However, isolated LCHAD deficiency can also be consistent with long-term survival in patients identified and treated from an early age. We present biochemical, clinical and mutation data in 9 patients spanning the full spectrum of disease. Fibroblast acylcarnitine profiling shows good correlation with clinical phenotype using the ratio C18(OH)/(C14(OH)+C12(OH)). This ratio shows a gradation of values, from high in four patients with severe neonatal disease (2.5+/-0.8), to low in two neuromyopathic patients (0.35, 0.2). Fibroblast fatty acid oxidation flux assays also show correlation with the patient phenotype, when expressed either as percentage residual activity with palmitate or as a ratio of percentage activity of myristate/oleate (M/O ratio). Fibroblasts from four patients with severe neonatal disease gave an M/O ratio of 4.0+/-0.6 compared to 1.97 and 1.62 in two neuromyopathic patients. Specific enzyme assay of LCHAD and long-chain 3-ketothiolase activity in patient cells shows lack of correlation with phenotype. These results show that measurements in intact cells, which allow all determinative and modifying cellular factors to be present, better reflect patient phenotype. Mutation analysis reveals a number of alpha- and beta-subunit mutations. Peripheral sensorimotor polyneuropathy, often as the initial major presenting feature but usually later accompanied by episodic rhabdomyolysis, is a manifestation of mild TFP protein deficiency. The mild clinical presentation and relative difficulty in diagnosis suggest that this form of TFP is probably underdiagnosed.

Enterovirulent Escherichia coli are among the most important causes of acute diarrhea in developing as well as in developed countries. We have adapted classical PCR to detect these organisms in stool specimens to real-time PCR using the LightCycler (LC) SYBR Green format followed by melting curve analysis. With only two different cycling protocols we could detect enteropathogenic E. coli (EPEC) and verocytotoxin-producing E. coli (VTEC) (duplex assay for both Verotoxin 1 (VT1) and Verotoxin 2 (VT2)) in one run and enteroaggregative E. coli (EAEC), enteroinvasive E. coli (EIEC) and enterotoxigenic E. coli (ETEC) (duplex assay detecting both heat-stable enterotoxin (ST) and heat-labile enterotoxin (LT)) in another run. Using serial dilutions of control strains, the LC proved to be clearly more sensitive than conventional PCR for five out of seven investigated targets: VTEC (VT1 and VT2), ETEC (ST and LT) and EIEC. For EPEC and EAEC, LC and conventional PCR had identical sensitivities. With stool samples, we found an optimal agreement between LC-PCR and the conventional PCR when samples were tested in a 1:10 dilution. Only one specimen was discrepant, being repetitively positive for VT by LightCycler but not by conventional PCR. Given the significantly higher sensitivity of the LC-PCR for the VT target (up to a 10(-4) dilution factor by melting curve analysis and up to a 10(-6) dilution factor following gel electrophoresis), this is probably a false negative result by conventional PCR. We conclude that LightCycler PCR is more rapid, easier than and at least as sensitive as our conventional PCR for the detection of enterovirulent E. coli in stool specimens after culture on MacConkey.
