Congenital Harlequin syndrome as an isolated phenomenon: A case report and review of the literature.

UNLABELLED: Harlequin syndrome (HS) is a rare autonomic disorder due to a hemifacial cutaneous sympathetic denervation. It is characterized by unilateral diminished sweating and flushing of the face even though after heat or prolonged exercise. It is typically acquired. Congenital cases only represent a 6% of all individuals with HS. All congenital HS cases reported so far showed a concomitant Horner syndrome, probably due to a stellate ganglion involvement. HS represents an uncommon autonomic disorder due to a hemifacial cutaneous sympathetic denervation. It is clinically characterized by a dramatic alteration in facial appearance: ipsilateral denervated pale and dry half from the other intact red and moist half. CONCLUSION: We present, to the best of our knowledge, the first case of a patient with a congenital HS as an isolated phenomenon.

Luminescent pentafluorophenyl-cycloplatinated complexes: synthesis, characterization, photophysics, cytotoxicity and cellular imaging.

Luminescent mono(pentafluorophenyl) cycloplatinated complexes [Pt(C^N-κC,N)(HC^N-κN)(C6F5)] [HC^N = Hthpy (2-(2-thienyl)pyridine) 2a, Hbt (2-phenylbenzothiazole) 2b, Hpq (2-phenylquinoline) 2c] have been prepared by C­H activation of a HC^N ligand in the corresponding [Pt(HC^N-κN)2(C6F5)2] (1a, 1b, 1c) complexes. Complexes 2 evolve in DMSO solution into solvate complexes and we present here successful routes for the synthesis of [Pt(C^N)(C6F5)(DMSO)] (C^N = thpy 3a, bt 3b). They have been fully characterized (X-ray for 1a, 1c, 2b, 3a and 3b), their electronic absorption and emission properties have been investigated and DFT and TD-DFT calculations for 1a, 1c, 2b and 3a have been carried out. Complexes 3a, 3b and [Pt(ppy)(C6F5)(DMSO)] 4 (Hppy = 2-phenylpyridine) show remarkable stability in a mixed DMSO-cellular medium and their cytotoxicity towards the human lung tumor (A549) and bronchial epithelial non-tumorigenic (NL20) cell lines has been evaluated by MTS assays. Their cellular localization in A549 and NL20 human cells and in mouse embryonic fibroblasts obtained from lungs (LMEFs) has also been investigated by fluorescence microscopy.

[Coding in neuropediatrics based on the International Classification Diseases, 9th revision (ICD-9), 5th edition (2006)]. / Codificación en neurología pediátrica basada en la Clasificación Internacional de Enfermedades, 9.(a) revisión (CIE-9), 5.(a) edición (2006).

AIMS: To analyze International Classification Diseases, 9th revision (ICD-9) coding and adapt it, on a consensus basis, to 'reasons for medical consultation', 'diagnoses' and 'procedures' in child neurology. MATERIALS AND METHODS: The most frequent reasons for medical consultation, diagnoses and procedures in neuropediatrics were selected and assigned the most appropriate ICD-9, Clinical Modification (5th ed.) (ICD-9-CM) codes in accordance with this system's coding rules. Disorders were grouped by sections, and allocated to the various members of the working group (13 child neurologists from 10 hospitals in Madrid and environs). RESULTS: Available on the web www.neurologia.com/cie-9. ICD-9-CM codes were assigned to: 158 reasons for medical consultation; 886 diagnoses; 73 diagnostic procedures; and 53 therapeutic procedures. In every case, the most appropriate ICD-9 code was sought for the respective diagnosis. No codes were invented but the working group did take certain liberties with interpretation, which nevertheless showed respect for general ICD-9-CM philosophy and are described in full in the text. CONCLUSIONS: The creation of this ICD-9 adaptation will not only enhance diagnostic coding in child neurology departments, but will also provide them with a useful tool for setting up databases to enable information to be retrospectively analyzed and shared by the different health centers.

Integration of new CAPS and dCAPS-RGA markers into a composite chickpea genetic map and their association with disease resistance.

A composite linkage map was constructed based on two interspecific recombinant inbred line populations derived from crosses between Cicer arietinum (ILC72 and ICCL81001) and Cicer reticulatum (Cr5-10 or Cr5-9). These mapping populations segregate for resistance to ascochyta blight (caused by Ascochyta rabiei), fusarium wilt (caused by Fusarium oxysporum f. sp. ciceris) and rust (caused by Uromyces ciceris-arietini). The presence of single nucleotide polymorphisms in ten resistance gene analogs (RGAs) previously isolated and characterized was exploited. Six out of the ten RGAs were novel sequences. In addition, classes RGA05, RGA06, RGA07, RGA08, RGA09 and RGA10 were considerate putatively functional since they matched with several legume expressed sequences tags (ESTs) obtained under infection conditions. Seven RGA PCR-based markers (5 CAPS and 2 dCAPS) were developed and successfully genotyped in the two progenies. Six of them have been mapped in different linkage groups where major quantitative trait loci conferring resistance to ascochyta blight and fusarium wilt have been reported. Genomic locations of RGAs were compared with those of known Cicer R-genes and previously mapped RGAs. Association was detected between RGA05 and genes controlling resistance to fusarium wilt caused by races 0 and 5.

Selection of housekeeping genes for normalization by real-time RT-PCR: analysis of Or-MYB1 gene expression in Orobanche ramosa development.

Real-time PCR has become the method of choice for accurate and in-depth expression studies of candidate genes. To avoid bias, real-time PCR is referred to one or several internal control genes that should not fluctuate among treatments. A need for reference genes in the parasitic plant Orobanche ramosa has emerged, and the studies in this area have not yet been evaluated. In this study, the genes 18S rRNA, Or-act1, Or-tub1, and Or-ubq1 were compared in terms of expression stability using the BestKeeper software program. Among the four common endogenous control genes, Or-act1 and Or-ubq1 were the most stable in O. ramosa samples. In parallel, a study was carried out studying the expression of the transcription factor Or-MYB1 that seemed to be implicated during preinfection stages. The normalization strategy presented here is a prerequisite to accurate real-time PCR expression profiling that, among other things, opens up the possibility of studying messenger RNA levels of low-copy-number-like transcription factors.

Development of a new diagnostic marker for growth habit selection in faba bean (Vicia faba L.) breeding.

Faba bean varieties with determinacy of the apical meristem are relevant to green production. A diagnostic CAPS (cleavage amplification polymorphic sequence) marker for determinate growth habit (ti) in faba bean was previously developed by Avila et al. (Mol Breed 17:185-190, 2006) but was effective only on a limited range of cultivars or genotypes. In this study, we studied the reasons for this limited application and developed a new marker useful for most faba bean-breeding programs. By designing a new set of primers, the complete genomic Vf_TFL1 sequences from different genotypes contrasting for the character were obtained and additional base changes associated with the ti phenotype were identified. The comparison among faba bean sequences showed that the previous CAPS marker was based on a SNP (single nucleotide polymorphism) at position 469 in the intron 2-3, a silent mutation. On the contrary, a SNP at position 26 that distinguishes determinate and indeterminate growth habit genotypes lead to an amino acid change (Leu-9 to Arg) in the determinate growth habit genotypes that could account for the ti phenotype. A dCAPS marker based on this SNP that creates a TaqI site in the ti allele was developed. The marker was 100% successful in predicting ti phenotypes in a broad range of faba bean germplasm representing all major cultivars historically grown in Europe. The outcome confirms the utility of the new dCAPS in worldwide marker-assisted selection programs.

CAPs markers to assist selection for low vicine and convicine contents in faba bean (Vicia faba L.).

The antinutritional factors (ANFs) present in Vicia spp. seeds are a major constraint to the wider utilization of these crops as grain legumes. In the case of faba bean (Vicia faba L.), a breeding priority is the absence vicine and convicine (v-c); responsible for favism in humans and for the reduced animal performance or low egg production in laying hens. The discovery of a spontaneous mutant allele named vc-, which induces a 10-20 fold reduction of v-c contents, may facilitate the process. However, the high cost and difficulty of the chemical detection of v-c seriously restricts the advances in breeding-selection. To identify random amplified polymorphic DNA (RAPD) markers linked to this gene, we have analysed an F(2 )population derived from a cross between a line with high v-c content (Vf6) and the vc- genotype (line 1268). Quantification of v-c was done by spectrophotometry on the parents and the F(2 )population (n = 136). By using bulked segregant analysis (BSA), two RAPD markers linked in coupling and repulsion phase to the allele vc- were identified and further converted into sequence characterized amplified regions (SCARs). Amplification of SCARS was more consistent, although the initial polymorphism between pools was lost. To recover the polymorphisms several approaches were explored. Restriction digestion with HhaI (for SCAR SCH01(620)) and RsaI (for SCAR SCAB12(850)) revealed clear differences between the parental lines. The simultaneous use of the two cleavage amplified polymorphism (CAP) markers will allow the correct fingerprinting of faba bean plants and can be efficiently used in breeding selection to track the introgression of the vc- allele to develop cultivars with low v-c content and improved nutritional value.

A linkage map of chickpea (Cicer arietinum L.) based on populations from Kabuli x Desi crosses: location of genes for resistance to fusarium wilt race 0.

Two recombinant inbred line (RIL) populations derived from intraspecific crosses with a common parental line (JG62) were employed to develop a chickpea genetic map. Molecular markers, flower colour, double podding, seed coat thickness and resistance to fusarium wilt race 0 (FOC-0) were included in the study. Joint segregation analysis involved a total of 160 markers and 159 RILs. Ten linkage groups (LGs) were obtained that included morphological markers and 134 molecular markers (3 ISSRs, 13 STMSs and 118 RAPDs). Flower colour (B/b) and seed coat thickness (Tt/tt) appeared to be linked to STMS (GAA47). The single-/double-podding locus was located on LG9 jointly with two RAPD markers and STMS TA80. LG3 included a gene for resistance to FOC-0 (Foc0(1)/foc0(1)) flanked by RAPD marker OPJ20(600) and STMS marker TR59. The association of this LG with FOC-0 resistance was confirmed by QTL analysis in the CA2139 x JG62 RIL population where two genes were involved in the resistance reaction. The STMS markers enabled comparison of LGs with preceding maps.

Cross-species amplification of Medicago truncatula microsatellites across three major pulse crops.

Model plants are facilitating the genetic characterization and comparative mapping of a number of traditional crops. Medicago truncatula has been widely accepted as a model plant to this end as it provides the essential tools for multiple aspects of legume genetics and genomics. A large set of markers from highly conserved M. truncatula gene regions is being created and used to establish a worldwide framework for comparative genomic studies in legumes. We have investigated the potential for cross-species amplification of 209 expressed sequence tag (EST)-based and 33 bacterial artificial chromosome (BAC)-based microsatellites from M. truncatula in the three most important European legume pulses-pea, faba bean and chickpea-that might facilitate future comparative mapping. Our results revealed significant transferability of M. truncatula microsatellites to the three pulses (40% in faba bean, 36.3% in chickpea and 37.6% in pea). The percentage of M. truncatula EST-SSRs (simple sequence repeats) amplified in the three crops (39-43%) was twofold higher than that of the genomic SSRs (21-24%). Sequence analysis determined that the level of conservation in the microsatellite motif was very low, while the flanking regions were generally well conserved. The variations in the sequences were mainly due to changes in the number of repeat motifs in the microsatellite region combined with indel and base substitutions. None of the functional microsatellites showed direct polymorphism among the parental genotypes tested, consequently preventing their immediate use for mapping purposes.

Neumonía varicelosa en un paciente inmunocomprometido / Varicella pneumonia in an immunocompromised patient

La varicela es una enfermedad contagiosa y con carácter habitualmente benigno. La mayoría de los casos aparecen en la edad infantil y, en pocas ocasiones, cursan con complicaciones. Las más frecuentes son la sobreinfección de las lesiones, la laringitis y la neumonía, así como la encefalitis con cerebelitis. Los neonatos, adultos y los pacientes inmunocomprometidos constituyen el grupo de mayor riesgo. Se presenta el caso de un niño de cuatro años afectado por el síndrome de Cockayne que desarrolló una neumonía varicelosa de evolución fatal. El paciente había recibido tratamiento con corticoides y ciclosporina A durante el año previo a contraer la enfermedad para control de un síndrome nefrótico secundario a mínimos cambios. La neumonía por virus de la varicela es raramente descrita en la bibliografía pediátrica. Este paciente no había recibido vacunación previa. La instauración de un programa de vacunación contra la varicela en la población pediátrica beneficiaría la gran morbilidad de esta enfermedad, así como sus complicaciones derivadas de ella

Varicella is a highly contagious disease that is usually benign in nature. It generally occurs during childhood and complications seldom develop. The most common complications are superinfection of the cutaneous lesions, laryngitis and pneumonia, as well as encephalitis with cerebellitis. New-borns, adults and immunocompromised children present the groups at highest risk. We present the case of a 4-year-old boy with Cockayne syndrome who developed varicella pneumonia that resulted in death. The patient had been receiving corticosteroids and cyclosporine A for one year prior to contagion to treat minimal change nephrotic syndrome. Varicella pneumonia is rarely reported in the pediatric literature. Our patient had not been vaccinated. The establishment of an immunization program against varicella for the pediatric population would help to forestall the morbidity and complications associated with this disease

Hipertensión renovascular en la infancia / Renovascular hypertension in children

El objetivo de este trabajo es conocer los datos epidemiológicos, etiología, clínica al diagnóstico, tratamiento y evolución de la hipertensión arterial renovascular en nuestro medio. Se realizó una revisión retrospectiva de los niños con esta enfermedad diagnosticados en el Hospital Universitario Materno-Infantil de Canarias, de enero de 1993 a diciembre de 2001.Seis pacientes, con edades comprendidas entre los cuatro meses y los siete años, fueron diagnosticados de hipertensión renovascular. La clínica fue inespecífica en cinco pacientes (83,3%). Se demostraron complicaciones cardiacas en todos los pacientes. Los diagnósticos establecidos fueron: 4 pacientes con displasia fibromuscular, 1 con neurofibromatosis, y 1 con síndrome de aorta abdominal. Se efectuaron seis angioplastias percutáneas trasluminales (APT): cuatro como primera elección y dos en segunda alternativa. Tres pacientes recibieron tratamiento médico. Dos niños precisaron nefrectomía para control de la hipertensión arterial. El tiempo medio de seguimiento en consulta fue de 5,8 años (2,5-8 años). Se perdió el seguimiento de un paciente. Dos pacientes (20%) precisan tratamiento farmacológico para control de la presión arterial. Se recomienda valorar la APT como tratamiento de elección de la hipertensión renovascular. Se produjo una alta incidencia de complicaciones neurológicas y cardiacas. Una tercera parte de los pacientes quedaron monorrenos, aunque todos mantienen una función renal dentro de la normalidad

The aim of this study was to assess the epidemiological data, etiology, diagnosis, treatment and course of arterial renovascular hypertension in our pediatric population. For this purpose, we carried out a retrospective review of the children diagnosed as having renovascular hypertension in our hospital between January 1993 and December 2001.Six patients, ranging in age between 4 months and 7 years old, were diagnosed as having renovascular hypertension. The clinical findings were nonspecific in 5 patients (83.3%). All six patients had cardiac complications. The diagnosis was fibromuscular dysplasia in four cases, neurofibromatosis in one and abdominal aorta syndrome in one. All the patients underwent percutaneous transluminal angioplasty (PTA), as the treatment of first choice in four and as a second option in the other two. Three patients received medical treatment. Two of the children required nephrectomy to control arterial hypertension. The mean length of outpatient follow-up is 5.8 years (range: from 2.5 to 8 years). One patient was lost to follow-up. Two patients required pharmacological treatment in order to control their blood pressure. We recommend that PTA be considered as the possible treatment of choice for renovascular hypertension. We report a high incidence of neurological and cardiac complications. One third (n= 2) of our patients have only one kidney, although all of them present normal renal function

Sources of Resistance to Crenate Broomrape Among Species of Vicia.

Crenate broomrape is a parasitic weed that represents a major constraint for pulse and forage legume production in the Mediterranean and West Asia regions. Control strategies have centered around agronomic practices and the use of herbicides, although success has been marginal. Resistance breeding is hampered by scarcity of proper sources of resistance and of a reliable and practical screening procedure. A germ plasm collection of 208 accessions of vetch belonging to 42 Vicia spp. was screened for resistance to crenate broomrape under field conditions. High levels of resistance were found in several species. Resistance of selected accessions was confirmed by a low induction of broomrape seed germination in pot and in vitro experiments. This was followed by a scarce establishment of broomrape radicles in contact with host roots and a limited development of established tubercles. In addition, a hypersensitive-like necrosis occasionally was observed, but at low frequency.

Isolate and organ-specific QTLs for ascochyta blight resistance in faba bean ( Vicia faba L).

The main objective of the present study was to locate the genomic regions responsible for ascochyta blight resistance in faba bean. Six QTLs were identified with the help of a linkage map constructed from a F(2) population from the cross between the inbred lines 29H (resistant) and VF136 (susceptible). Two pathogenically distinct Ascochyta isolates were used to study the genetic control against them and disease evaluations were performed separately on leaves and stems to investigate whether different genetic systems control resistance in each plant organ, as previously suggested. The six QTLs detected were named Af3 to Af8. Af3 and Af4 were effective against both Ascochyta isolates, Af5 was only effective against isolate CO99-01 while Af6, Af7 and Af8 were only effective against isolate LO98-01. Af3, Af4, Af5 and Af7 were revealed in both leaves and stems. By contrast, Af6 was only effective in leaves and Af8 only in stems. The validity and application of these results in a MAS program is discussed.
