Abstract
Recent studies have revealed that the Par-1 protein, in addition to its established role in anterior-posterior patterning of the Drosophila oocyte, has both microtubule-dependent and microtubule-independent roles very early in oogenesis.

Abstract
BACKGROUND Fourteen genetically distinct forms of limb-girdle muscular dystrophy (LGMD) have been identified, including five types of autosomal dominant LGMD (AD-LGMD). OBJECTIVE To describe clinical, histologic, and genetic features of a large Spanish kindred with LGMD and apparent autosomal dominant inheritance spanning five generations. METHOD The authors examined 61 members of the family; muscle biopsies were performed on five patients. Linkage analysis assessed chromosomal loci associated with other forms of AD-LGMD. RESULTS A total of 32 individuals had weakness of the pelvic and shoulder girdles. Severity appeared to worsen in successive generations. Muscle biopsy findings were nonspecific and compatible with MD. Linkage analysis to chromosomes 5q31, 1q11-q21, 3p25, 6q23, and 7q demonstrated that this disease is not allelic to LGMD forms 1A, 1B, 1C, 1D, and 1E. CONCLUSIONS This family has a genetically distinct form of AD-LGMD. The authors are currently performing a genome-wide scan to identify the disease locus.

Abstract
APETALA1 (AP1) and its homologue SQUAMOSA (SQUA) are key regulatory genes specifying floral meristem identity in the model plants Arabidopsis and Antirrhinum. Despite many similarities in their sequence, expression and functions, only AP1 appears to have the additional role of specifying sepal and petal identity. No true AP1/SQUA-functional homologues from any other plant species have been functionally studied in detail, therefore the question of how the different functions of AP1-like genes are conserved between species has not been addressed. We have isolated and characterized PEAM4, the AP1/SQUA-functional homologue from pea, a plant with a different floral morphology and inflorescence architecture to that of Arabidopsis or Antirrhinum. PEAM4 encodes for a polypeptide 76% identical to AP1, but lacks the C-terminal prenylation motif, common to AP1 and SQUA, that has been suggested to control the activity of AP1. Nevertheless, constitutive expression of PEAM4 caused early flowering in tobacco and Arabidopsis. In Arabidopsis, PEAM4 also caused inflorescence-to-flower transformations similar to constitutive AP1 expression, and was able to rescue the floral organ defects of the strong ap1-1 mutant. Our results suggest that the control of both floral meristem and floral organ identity by AP1 is not restricted to Arabidopsis, but is extended to species with diverse floral morphologies, such as pea.

Abstract
Thorough non-invasive cardiovascular studies were conducted in a series of ten gamma-sarcoglycanopathy Gypsy patients with the founder C283Y mutation in 13q12. Results were compared with those obtained in an age-matched group of normal boys and girls. The studies included electrocardiographic and echocardiographic evaluations using pulsed wave Doppler tissue imaging to assess regional diastolic function and myocardial velocities at various levels. This study confirms the significant electrocardiographic abnormalities described in previous studies. Furthermore, measurement of myocardial velocity at different levels demonstrated an abnormal relaxation pattern in the tricuspid annulus in four of the oldest patients, which strongly suggests intrinsic myocardial involvement of the right ventricle. To our knowledge, these specific studies have not been previously performed in a clinically and genetically homogeneous group of gamma-sarcoglycanopathy patients and suggest primary myocardial involvement probably due to gamma-sarcoglycan deficiency in cardiac muscle fibres. Our results could be of interest in the follow-up of these patients and the prevention and treatment of late cardiological complications.

Abstract
A few of the known associations between paediatric cancer and congenital anomalies are attributable to contiguous-gene syndromes. Neuroblastoma (NB) has been linked with an excess of gastrointestinal malformations, but there is a significant scarcity of associated respiratory anomalies. We report on two children having an abdominal NB and a bronchogenic cyst diagnosed simultaneously and in different order of appearance. Both masses were removed in separated procedures, taking into account the priority and the time sequence of chemotherapy. Literature is reviewed, checking that the genetic basis for this association is supported by speculations about the oncogene RON.

Abstract
BACKGROUND Although the fatty acid fractions provide similar metabolizable energy, the type of dietary fat consumed could be relevant to the development of obesity. OBJECTIVE To investigate the relationship between body mass index (BMI), obesity and the consumption of different types of fat and olive oil in a Mediterranean country with high prevalence of obesity, and high intake of monounsaturated fatty acids (MUFA) and olive oil. SUBJECTS The study was carried out in Spain among 23 289 women and 14 374 men, aged 29-69 years, who were participants of a large European prospective cohort. METHODS : Information on usual food intake was collected by interviewers by means of a dietary history questionnaire. The association between obesity (BMI >/= 30 kg m2), dietary fat, other dietary patterns and other non-dietary factors were tested using multilinear regression analysis. The ratio of reported energy intake to energy requirement was used as an estimation of dietary underreporting. RESULTS The association between fatty acid fractions intake (saturated fatty acids (SFA) in women, and MUFA and polyunsaturated fatty acids (PUFA) in both sexes) and BMI was very weak, accounting for less than 1% of variance. All dietary and non-dietary variables accounted for 21% of variance in the measurement of BMI in women and only 6.7% of variance in men. Estimated underreporting of energy intake was 17.5% in obese women and 5.5% in obese men. CONCLUSIONS The association between consumption of specific types of dietary fat, olive oil and obesity in Spain is not very important. However, because of the cross-sectional design and some level of underreporting of energy intake observed in overweight subjects and overreporting in underweight subjects, systematic bias cannot be completely discarded.

Abstract
We found six patients with AMPD deficiency in muscle who were homozygous for the most common mutation, Q12X in the AMPD gene (AMPD1), associated with this disease. Three patients had AMPD deficiency alone, showing a mild clinical phenotype. Two patients showed a defect of PPL in muscle, and were homozygous for the most common mutation associated with McArdle's disease, R49X in the muscle PPL gene (PYGM). In one of these patients, the clinical phenotype was more severe than usually seen in patients with McArdle's disease. The remaining patient harbored the mtDNA A3243G mutation, showing one of the usual clinical patterns associated with this mutation. We conclude that the Q12X mutation in AMPD1 may result in a mild clinical effect; that it is frequent in the Spanish population, and therefore frequently associated with other metabolic diseases; and that the effect of the association of AMPD and PPL deficiencies seems to be neutral.

Abstract
BACKGROUND The aim of this study was to assess the susceptibility to penicillin of Streptococcus pneumoniae clinical strains and to analyze the association between penicillin resistance and cefotaxime and cefixime activity in S. pneumoniae isolates with decreased sensitivity to penicillin. METHODS 301 S. pneumoniae clinical strains were isolated from patients during 1995-1996. Susceptibility to penicillin, cefotaxime, cefepime, erythromycin, chloramphenicol, tetracycline, cotrimoxazole and ciprofloxacin were studied. RESULTS 38.2% isolates were penicillin-susceptible and 61.8% were penicillin-resistant; 20.6% showed high-level resistance. Resistance rates to erythromycin, chloramphenicol, tetracycline, cotrimoxazole and ciprofloxacin were, respectively, 30.9, 30.2, 40.9, 66.4, and 13.3% overall, and 54.8, 54.8, 61.3, and 93.5% in the 62 strains with high-level resistance to penicillin. Strains resistant to cefotaxime and cefepime were 13.9 and 14.9%, respectively. MIC50 and MIC90 for cefotaxime and cefepime in penicillin-resistant strains were 0.5 and 1 mg/ml. CONCLUSIONS A high proportion of S. pneumoniae isolates showed resistance to penicillin, in agreement with other Spanish reports. Moreover, resistance to penicillin was significantly associated (p < 0.001) with resistance to erythromycin, chloramphenicol, tetracycline and cotrimoxazole, but not with ciprofloxacin. MIC50 and MIC90 for cefotaxime and cefepime were similar, and lower than those for penicillin in penicillin-resistant pneumococci strains.

Abstract
There is an intricate network of molecules called cell fate determinants that instruct the cells of the embryo to take on either an anterior or posterior fate. In a lively Perspective, Lehmann and her colleagues discuss new findings in the fruit fly that identify a key protein, PAR-1, which ensures that the cell fate determinants are themselves located in the correct region of the oocyte. In this way, the anterior-posterior axis is set up in the fruit fly egg before fertilization.

Abstract
Cyfra 21-1 has been reported to be an effective tumor marker for epithelial carcinomas. The purpose of this investigation was to determine its value in evaluating response to treatment in patients with carcinoma of the cervix. Cyfra 21-1 levels were measured by immunoassay in the serum of 55 untreated patients with cervical cancer; a second sample was obtained in all of them after conventional treatment for association with clinical response. Pre-therapy levels were elevated in only 45% (25 of 55) of the patients, with a slight tendency to increase according to clinical stage: 33% (5/15) in stage I, 36% (8/22) in stage II and 67% (12/18) in stage III. In regards to association with response to therapy, and including patients with either normal or elevated pretreatment values, 46% (19/41) of women with a complete clinical response either persisted with or developed elevated levels after treatment completion. All 14 patients with persistent disease after therapy continued to have or developed elevated values. No patient with persistent disease had normal values after therapy, and all patients with negative values after treatment were truly complete clinical responders. The results of our study suggest that the test has a low sensitivity therefore and, despite our findings, a negative level after treatment may not be a safe indicator of disease-free status. On the other hand, an elevated post-treatment level is not a reliable indicator of persistence, proven by the fact that 46% of clinical responders fell in this category. Therefore, Cyfra 21-1 has a very limited role in correlating with response to treatment in carcinoma of the cervix.

Abstract
BACKGROUND To evaluate lifestyle and dietary intake factors influencing the accumulation of abdominal fat in a Mediterranean population. SUBJECTS AND METHOD A cross-sectional study was carried-out in Spain (Asturias, Granada, Murcia, Navarra and Guipuzkoa) among 23,228 women and 14,332 men aged 29-69 years, participants of a large European prospective cohort (EPIC). Information on usual food intake and other non-dietary factors were collected by interviews. Height, weight, waist circumference and hip circumference were taken by previously trained interviewers. RESULTS In a multiple-linear regression analysis sports activities and educational level were negatively associated with abdominal obesity, while body mass index, age, tobacco and alcohol consumption, saturated fat intake and increased prevalence of hypertension, diabetes and myocardial infarction were positively associated. All dietary and non-dietary variables accounted for 22 and 27% of variance in the waist/hip ratio and 74 and 66% of variance in the waist circumference, in women and men respectively. CONCLUSIONS Body mass index and age are the most important factors influencing the accumulation of abdominal fat. Dietary factors and other lifestyle factors seem to play a minor role in increasing abdominal obesity.

Abstract
OBJECTIVE To characterize the clinical phenotype of LGMD2C in gypsies. BACKGROUND Limb-girdle muscular dystrophy (LGMD) in gypsies of Western Europe is caused by a homozygous C283Y mutation on the same haplotype, suggesting a founder effect. METHODS We performed clinical, laboratory, and muscle imaging studies of 40 patients. RESULTS Mean age at onset was 5.3 years. One half of the patients had loss of ambulation by the age of 12; 13% still could walk after age 16. Calf hypertrophy, scapular winging, macroglossia, and lumbar hyperlordosis were common. Girdle, trunk, and proximal limb flexor muscles had earlier and more severe involvement. Cardiomyopathy was not observed. Five patients in the third decade of life required mechanical ventilation. Scoliosis was common in the nonambulatory stage. CONCLUSIONS LGMD2C in gypsy patients with C283Y mutation presents a rather homogeneous phenotype, characterized by an initial Duchenne-like progressive course followed by a more prolonged survival rate possibly due to the absence of early respiratory impairment and cardiac failure.

Abstract
STUDY OBJECTIVE High blood pressure is a variable related to several chronic conditions whose repeated measurement in large cohort studies is often not feasible having to rely on the self reporting of the subjects. The aim of the study is to validate such self diagnosis in a sample of members from the Spanish EPIC cohort study. DESIGN Comparison of high blood pressure self diagnosis with the information provided by the personal medical record drawn from the primary health centre of reference for such population. SETTING A small town near the EPIC-Murcia centre, one of five Spanish EPIC centres located in the south east, where inclusion in the cohort was offered to the general population. PARTICIPANTS The agreement between self reported high blood pressure status and data from medical records was measured in a representative sample of men and women (n = 248) aged 30-69 years. Medical records were studied for a diagnosis of high blood pressure, an anti-hypertensive pharmacological treatment or subject's inclusion in a hypertension control programme run in the medical centre only for hypertensive people (definite high blood pressure cases). As well, in the absence of such a diagnosis, medical annotations of systolic or diastolic high blood pressure > or = 140/90 mm Hg (possible high blood pressure cases) were considered. Sensitivity, specificity, positive and negative predictive values and kappa scores were calculated for all, definite and possible high blood pressure cases. Variables associated with the probability of having a true positive or negative self report of high blood pressure were also tested. MAIN RESULTS As expected, sensitivity was higher among definite cases (72.7%) than among possible cases (31.6%). Accordingly, the agreement between self report and medical record was higher for definite cases (kappa = 0.65) than for possible (kappa = 0.29 cases leading to a moderate overall agreement for all cases (kappa = 0.58; 95% CI: 0.47, 0.69). Having some level of education (OR: 0.31; 95% CI: 0.09, 1.05) was negatively associated to a true self report of high blood pressure while being female was positively associated (OR: 4.01; 95% CI 1.04, 16.8). No variable showed any association with having a true self report of being normotensive. CONCLUSIONS High blood pressure self report shows a moderate agreement with medical information in this cohort allowing it to be used, with caution, as a surrogate variable of actual blood pressure status. However, because of its moderate sensitivity, it is not possible to rule out some underestimation when using self reported high blood pressure information for high blood pressure frequency measurements such as prevalence or incidence rates. This underestimation will be higher among men and educated people.

Abstract
From January 1996 to December 1997, we evaluated the in vitro activity of 8 antimicrobials (penicillin, amoxycillin, amoxycillin/clavulanate, cefuroxime, ceftazidime, cefepime, cefotaxime, and imipenem) against 350 Streptococcus pneumoniae clinical isolates collected from two hospitals. Imipenem, cefepime and cefotaxime were the most active antibiotics against penicillin-intermediate (PI) and highly penicillin-resistant (PR) S. pneumoniae with MICs 2- to 8-fold lower than penicillin. Against PI and PR pneumococci amoxycillin and amoxycillin/clavulanate were 2-times less active than cefepime and cefotaxime, while cefuroxime was 4-8-times less active. The majority of strains of serotypes 6B, 23F, 14, 9 and 19 were penicillin-resistant, both intermediate (68%) and highly resistant (32%).

OBJECTIVE To investigate the degree of genetic heterogeneity of myophosphorylase deficiency (McArdle disease) in Spain through molecular studies of 10 new patients. DESIGN The coding sequence of the entire myophosphorylase gene was sequenced in DNA extracted from muscle and blood. Restriction fragment length polymorphism analysis of polymerase chain reaction fragments was used to confirm and simplify detection of a novel mutation. SETTING A collaborative study between 2 university laboratories in Spain and the United States. RESULTS Five of the 10 patients harbored a novel missense mutation in exon 20, converting a tryptophan to an arginine (W797R). Three patients were homozygous for the "common" R49X mutation, and the remaining 2 patients were compound heterozygotes for R49X and a previously described missense mutation, G204S. CONCLUSIONS The W797R missense mutation is the third novel mutation to be identified among Spanish patients. Its relative frequency suggests that it should be added to the R49X mutation in the molecular screening of McArdle disease in Spain.

Abstract
OBJECTIVE Hypertrophic osteoarthropathy (HOA) is characterized by the coexistence of digital clubbing and periosteal proliferation of the tubular bones. Localized vascular proliferation associated with platelet/endothelial cell activation are recognized features of this syndrome. Current knowledge suggests that HOA develops from the presence in the systemic circulation of one or more growth factors that are normally inactivated in the lungs. The nature of these purported growth factors has not yet been identified. Vascular endothelial growth factor (VEGF) has several features that may fit in with the pathogenesis of HOA. The objective of our study was to measure serum and plasma levels of VEGF in different groups of patients with HOA. METHODS We studied 24 patients with HOA; of these, in 12 the HOA was secondary to cyanotic congenital heart disease and in 7 to lung cancer, while 5 represented primary cases. As controls we studied 28 individuals without HOA; of these, 12 were apparently healthy individuals, 7 had cyanosis secondary to chronic obstructive pulmonary disease, and 9 had lung cancer. ELISA was used to measure serum and plasma levels of VEGF. RESULTS Plasma levels of VEGF were significantly higher in the patients with primary HOA (median 46.2; range 19.4-398.8 pg/ml) and in those with lung cancer-HOA (median 75.5; range 24.6-166.7), compared to healthy controls (median 7.4; range: 0-26.1), p < 0.05. Serum VEGF levels were higher in patients with lung cancer and HOA (median 411.4; range 164.2-959.5 pg/ml) compared with lung cancer patients without HOA (median 74.5; range 13.2-205.4), p < 0.001. CONCLUSIONS Patients with primary HOA and those with HOA and lung cancer have increased circulating levels of VEGF. This cytokine may play a role in the pathogenesis of HOA.
