RESUMEN

The effect of biomass ash and clay on tomato plants (Lycopersicon esculentum) in greenhouse conditions from germination to production was studied. Biomass ash is a waste obtained from thermal treatment of guishe (a by-product of natural fiber), and clay is collected from local soils. Several trials were performed to assess the influence of the addition of clay and guishe-ash on seeds germination, seedling growth, and production yield. The decrease in the values of these variables was considered an indicator of toxicity. The obtained results showed that based clay/ash materials positively affect germination (average ∼90% and six materials allow obtaining 90%) and seedlings growth (an increase of ∼20% in height and more than 50% in fresh air corpuscular weight). However, applying these materials on the production stage induces minor positive effects on fruit diameter, locule number, pericarp thickness, and the number of seeds per fruit. Also, adverse effects (first harvest yield, number of fruits, fresh mass of ripe fruits, lycopene content) were observed. To valorize biomass ash, its combination with other materials such as clay could be an alternative to improve tomato production.


The concern to attend the growing demand for food has promoted the use of different kinds of materials as enhancers of plant growth and crop productivity. Among the materials that have been applied in crops are the wastes of biomass thermochemical processes, such as biochar and ashes. This work highlights the importance of evaluating the effect of applying a residue (guishe-ash) to a crop before promoting its use.

RESUMEN

INTRODUCTION: Patients with Down syndrome (DS) who exhibit Alzheimer disease (AD) are associated with age. Both diseases with a common neuropathological basis have been associated with late-onset myoclonic epilepsy (LOMEDS). This entity presents electroencephalogram features as generalized polyspike-wave discharges. METHOD: We present a series of 11 patients with the diagnosis of DS or AD who developed myoclonic seizures or generalized tonic-clonic seizures. In all cases, clinical and neuroimaging studies and polygraph EEG monitoring was performed. RESULTS: In all cases, cognitive impairment progressed quickly after the onset of epilepsy causing an increase in the degree of dependence. The most common finding in the EEG was a slowing of brain activity with theta and delta rhythms, plus intercritical generalized polyspike-waves were objectified in eight patients. In neuroimaging studies was found cerebral cortical atrophy. The most effective drug in this series was the levetiracetam. CONCLUSIONS: The association of generalized epilepsy with elderly DS represents an epiphenomenon in evolution which is associated with a progressive deterioration of cognitive and motor functions. This epilepsy has some electroclinical characteristics and behaves as progressive myoclonic epilepsy, which is probably related to the structural changes that characterize the evolutionary similarity of DS with AD. Recognition of this syndrome is important, since it has prognostic implications and requires proper treatment.

RESUMEN

INTRODUCTION: In-hospital consultations (IHC) are essential in clinical practice in tertiary hospitals. The aim of this study is to analyse the impact of neurological IHCs. PATIENTS AND METHOD: One-year retrospective descriptive study of neurological IHCs conducted from May 2013 to April 2014 at our tertiary hospital. RESULTS: A total of 472 patients were included (mean age, 62.1 years; male patients, 56.8%) and 24.4% had previously been evaluated by a neurologist. Patients were hospitalised a median of 18 days and 19.7% had been referred by another hospital. The departments requesting the most in-hospital consultations were intensive care (20.1%), internal medicine (14.4%), and cardiology (9.1%). Reasons for requesting an IHC were stroke (26.9%), epilepsy (20.6%), and confusional states (7.6%). An on-call neurologist evaluated 41.9% of the patients. The purpose of the IHC was to provide a diagnosis in 56.3% and treatment in 28.2% of the cases; 69.5% of the patients required additional tests. Treatment was adjusted in 18.9% of patients and additional drugs were administered to 27.3%. While 62.1% of cases required no additional IHCs, 11% required further assessment, and 4.9% were transferred to the neurology department. Of the patient total, 16.9% died during hospitalisation (in 37.5%, the purpose of the consultation was to certify brain death); 45.6% were referred to the neurology department at discharge and 6.1% visited the emergency department due to neurological impairment within 6 months of discharge. CONCLUSIONS: IHCs facilitate diagnosis and management of patients with neurological diseases, which may help reduce the number of visits to the emergency department. On-call neurologists are essential in tertiary hospitals, and they are frequently asked to diagnose brain death.

RESUMEN

BACKGROUND: The non-lethal variant of the Escobar or multiple pterygium syndrome is an entity of autosomal recessive inheritance linked to the X chromosome; it is characterized by multiple pterygia (hence its name) located mainly in the neck (95%) and armpits (55%), as well as other orthopedic malformations such as a vertical talus, congenital hip dislocation, and congenital scoliosis. OBJECTIVE: To present an optional surgical technique for the management of severe spinal deformities. CASE REPORT: Twelve-year-old female diagnosed with Escobar syndrome with severe scoliosis which conditions malformations of the chest with lung involvement, producing mechanical ventilatory restriction and increasing the risk of severe lower respiratory tract infection. We performed a hands-free posterior instrumentation with PASS LP system and Smith-Petersen osteotomies. CONCLUSIONS: The Cobb angle improved from 62° to 23° and the sagittal balance from 125 mm to 73 mm.

RESUMEN

INTRODUCTION AND OBJECTIVES: Chronic heart failure (CHF) is a disease with a high morbidity and mortality. The addition of spironolactone (25 mg/day) in the treatment of CHF has demonstrated a reduction in the mortality rate by 30% and in the hospitalization rate by 35%. The aim of this study was to perform a cost-benefit analysis of the association of spironolactone with the standard therapy for heart failure. METHODS: This analysis was carried out by assessing all the direct benefits and costs, derived from the association of either spironolactone or placebo with the standard therapy for heart failure in patients with functional degree III and IV. Data of costs and benefits were obtained from RALES. The following costs were included: hospitalisation, complementary tests and medication given. Benefit included avoided hospitalisations, complementary tests not performed and medication saved. The chosen perspective was the National Health Service and the time span chosen was of two years. RESULTS: The cost/patient in the spironolactone group (293,653 pts.) was lower than in placebo group (402,353 pts.). The benefit/patient in the former group (615,690 pts.) was higher than in the latter group (542,014 pts.). The net benefit (benefit-cost) of the spironolactone group (322,037 pts.) was higher than that observed in the placebo group (139,661 pts.). CONCLUSIONS: The association with spironolactone (25 mg/day) with the standard therapy for heart failure produces a remarkable net benefit in monetary terms. This fact will probably generate some resource saving for the National Health Service.

RESUMEN

We have compared the whole blood concentrations of parent cyclosporin A (CsA) using monoclonal fluorescence polarization immunoassay (FPIA) and radioimmunoassay (RIA) as well as polyclonal FPIA in kidney, heart, and bone marrow transplant patients (n = 89). A good correlation was found between monoclonal FPIA and monoclonal RIA (r = 0.96) and a slightly worse one between polyclonal and monoclonal FPIA (r = 0.90). The interassay coefficient of variation was satisfactory for all the methods-less than 5% for monoclonal FPIA. The monoclonal FPIA assay with Abbott TDx appears to provide rapid, precise, and accurate measurement of parent CsA. It is therefore useful for therapeutic monitoring of CsA in whole blood in kidney, heart, and bone marrow transplant patients.

RESUMEN

The TDx digoxin II immunoassay was used in controls and in patients not taking digoxin or any other cardiac glycoside. We report the frequency of interference thought to be caused by digoxin-like factors (DLFs). We found a high incidence of false-positive results in 15 patients with severe hepatic disease (60% false-positive results). In newborn infants we found false-positive results both when their blood was drawn from a peripheral vein (89% false-positive results) and, more strikingly (100% false-positive results), when it was obtained from an umbilical cord vein (p less than 0.001). Compared to a control group, no statistically significant false-positive results were found in patients with mild to moderate chronic renal failure (n = 21) or in pregnant women (n = 15). In patients with chronic renal failure undergoing hemodialysis six of 25 had false-positive results. These results suggest that digoxin levels must be interpreted carefully in patients with chronic liver disease and chronic renal failure and in newborns until new methods that eliminate the interference caused by DLFs become readily available.

RESUMEN

One hundred coagulase-negative staphylococci isolated from blood cultures of neonates have been biotyped and phage typed. These results have been compared with previous reports. The susceptibility of the strains to antimicrobial drugs has also been examined and a rise in resistance rates towards the end of the study was documented. The possible causes of this finding are discussed.

RESUMEN

The in vitro susceptibilities of 242 isolates of Serratia marcescens to 17 antibacterial drugs have been determined. Oxolinic acid, nalidixic acid, cefoxitin, and amikacin were the most active drugs. Ampicillin, kanamycin, and cephalothin were among the least active. A 4-year study showed that resistance of S. marcescens to dibekacin, tobramycin, sisomycin, and gentamicin has increased at least one order of magnitude in that period, whereas resistance to amikacin showed but a twofold increase.
