Delphi consensus on the diagnosis and treatment of patients with short stature in Spain: GROW-SENS study.

PURPOSE: To identify consensus aspects related to the diagnosis, monitoring, and treatment of short stature in children to promote excellence in clinical practice. METHODS: Delphi consensus organised in three rounds completed by 36 paediatric endocrinologists. The questionnaire consisted of 26 topics grouped into: (1) diagnosis; (2) monitoring of the small-for-gestational-age (SGA) patient; (3) growth hormone treatment; and (4) treatment adherence. For each topic, different questions or statements were proposed. RESULTS: After three rounds, consensus was reached on 16 of the 26 topics. The main agreements were: (1) diagnosis tests considered as a priority in Primary Care were complete blood count, biochemistry, thyroid profile, and coeliac disease screening. The genetic test with the greatest diagnostic value was karyotyping. The main criterion for initiating a diagnostic study was prediction of adult stature 2 standard deviations below the target height; (2) the main criterion for initiating treatment in SGA patients was the previous growth pattern and mean parental stature; (3) the main criterion for response to treatment was a significant increase in growth velocity and the most important parameter to monitor adverse events was carbohydrate metabolism; (4) the main attitude towards non-responding patients is to check their treatment adherence with recording devices. The most important criterion for choosing the delivery device was its technical characteristics. CONCLUSIONS: This study shows the different degrees of consensus among paediatric endocrinologists in Spain concerning the diagnosis and treatment of short stature, which enables the identification of research areas to optimise the management of such patients.

Code stroke in Asturias.

BACKGROUND: Intravenous thrombolysis with alteplase is an effective treatment for ischaemic stroke when applied during the first 4.5 hours, but less than 15% of patients have access to this technique. Mechanical thrombectomy is more frequently able to recanalise proximal occlusions in large vessels, but the infrastructure it requires makes it even less available. METHODS: We describe the implementation of code stroke in Asturias, as well as the process of adapting various existing resources for urgent stroke care in the region. By considering these resources, and the demographic and geographic circumstances of our region, we examine ways of reorganising the code stroke protocol that would optimise treatment times and provide the most appropriate treatment for each patient. RESULTS: We distributed the 8 health districts in Asturias so as to permit referral of candidates for reperfusion therapies to either of the 2 hospitals with 24-hour stroke units and on-call neurologists and providing IV fibrinolysis. Hospitals were assigned according to proximity and stroke severity; the most severe cases were immediately referred to the hospital with on-call interventional neurology care. Patient triage was provided by pre-hospital emergency services according to the NIHSS score. CONCLUSIONS: Modifications to code stroke in Asturias have allowed us to apply reperfusion therapies with good results, while emphasising equitable care and managing the severity-time ratio to offer the best and safest treatment for each patient as soon as possible.

Guidelines for the preventive treatment of ischaemic stroke and TIA (II). Recommendations according to aetiological sub-type.

BACKGROUND AND OBJECTIVE: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and Transient Ischaemic Attack (TIA). METHODS: We reviewed the available evidence on ischaemic stroke and TIA prevention according to aetiological subtype. Levels of evidence and recommendation levels are based on the classification of the Centre for Evidence-Based Medicine. RESULTS: In atherothrombotic IS, antiplatelet therapy and revascularization procedures in selected cases of ipsilateral carotid stenosis (70%-90%) reduce the risk of recurrences. In cardioembolic IS (atrial fibrillation, valvular diseases, prosthetic valves and myocardial infarction with mural thrombus) prevention is based on the use of oral anticoagulants. Preventive therapies for uncommon causes of IS will depend on the aetiology. In the case of cerebral venous thrombosis oral anticoagulation is effective. CONCLUSIONS: We conclude with recommendations for clinical practice in prevention of IS according to the aetiological subtype presented by the patient.

Guidelines for the treatment of acute ischaemic stroke.

INTRODUCTION: Update of Acute Ischaemic Stroke Treatment Guidelines of the Spanish Neurological Society based on a critical review of the literature. Recommendations are made based on levels of evidence from published data and studies. DEVELOPMENT: Organized systems of care should be implemented to ensure access to the optimal management of all acute stroke patients in stroke units. Standard of care should include treatment of blood pressure (should only be treated if values are over 185/105 mmHg), treatment of hyperglycaemia over 155 mg/dl, and treatment of body temperature with antipyretic drugs if it rises above 37.5 °C. Neurological and systemic complications must be prevented and promptly treated. Decompressive hemicraniectomy should be considered in cases of malignant cerebral oedema. Intravenous thrombolysis with rtPA should be administered within 4.5 hours from symptom onset, except when there are contraindications. Intra-arterial pharmacological thrombolysis can be considered within 6 hours, and mechanical thrombectomy within 8 hours from onset, for anterior circulation strokes, while a wider window of opportunity up to 12-24 hours is feasible for posterior strokes. There is not enough evidence to recommend routine use of the so called neuroprotective drugs. Anticoagulation should be administered to patients with cerebral vein thrombosis. Rehabilitation should be started as early as possible. CONCLUSION: Treatment of acute ischaemic stroke includes management of patients in stroke units. Systemic thrombolysis should be considered within 4.5 hours from symptom onset. Intra-arterial approaches with a wider window of opportunity can be an option in certain cases. Protective and restorative therapies are being investigated.

Clinical management guidelines for subarachnoid haemorrhage. Diagnosis and treatment.

OBJECTIVE: To update the Spanish Society of Neurology's guidelines for subarachnoid haemorrhage diagnosis and treatment. MATERIAL AND METHODS: A review and analysis of the existing literature. Recommendations are given based on the level of evidence for each study reviewed. RESULTS: The most common cause of spontaneous subarachnoid haemorrhage (SAH) is cerebral aneurysm rupture. Its estimated incidence in Spain is 9/100 000 inhabitants/year with a relative frequency of approximately 5% of all strokes. Hypertension and smoking are the main risk factors. Stroke patients require treatment in a specialised centre. Admission to a stroke unit should be considered for SAH patients whose initial clinical condition is good (Grades I or II on the Hunt and Hess scale). We recommend early exclusion of aneurysms from the circulation. The diagnostic study of choice for SAH is brain CT (computed tomography) without contrast. If the test is negative and SAH is still suspected, a lumbar puncture should then be performed. The diagnostic tests recommended in order to determine the source of the haemorrhage are MRI (magnetic resonance imaging) and angiography. Doppler ultrasonography studies are very useful for diagnosing and monitoring vasospasm. Nimodipine is recommended for preventing delayed cerebral ischaemia. Blood pressure treatment and neurovascular intervention may be considered in treating refractory vasospasm. CONCLUSIONS: SAH is a severe and complex disease which must be managed in specialised centres by professionals with ample experience in relevant diagnostic and therapeutic processes.

Clinical practice guidelines in intracerebral haemorrhage.

Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

Prediction of early stroke recurrence in transient ischemic attack patients from the PROMAPA study: a comparison of prognostic risk scores.

BACKGROUND: Several clinical scales have been developed for predicting stroke recurrence. These clinical scores could be extremely useful to guide triage decisions. Our goal was to compare the very early predictive accuracy of the most relevant clinical scores [age, blood pressure, clinical features and duration of symptoms (ABCD) score, ABCD and diabetes (ABCD2) score, ABCD and brain infarction on imaging score, ABCD2 and brain infarction on imaging score, ABCD and prior TIA within 1 week of the index event (ABCD3) score, California Risk Score, Essen Stroke Risk Score and Stroke Prognosis Instrument II] in consecutive transient ischemic attack (TIA) patients. METHODS: Between April 2008 and December 2009, we included 1,255 consecutive TIA patients from 30 Spanish stroke centers (PROMAPA study). A neurologist treated all patients within the first 48 h after symptom onset. The duration and typology of clinical symptoms, vascular risk factors and etiological work-ups were prospectively recorded in a case report form in order to calculate established prognostic scores. We determined the early short-term risk of stroke (at 7 and 90 days). To evaluate the performance of each model, we calculated the area under the receiver operating characteristic curve. Cox proportional hazards multivariate analyses determining independent predictors of stroke recurrence using the different components of all clinical scores were calculated. RESULTS: We calculated clinical scales for 1,137 patients (90.6%). Seven-day and 90-day stroke risks were 2.6 and 3.8%, respectively. Large-artery atherosclerosis (LAA) was observed in 190 patients (16.7%). We could confirm the predictive value of the ABCD3 score for stroke recurrence at the 7-day follow-up [0.66, 95% confidence interval (CI) 0.54-0.77] and 90-day follow-up (0.61, 95% CI 0.52-0.70), which improved when we added vascular imaging information and derived ABCD3V scores by assigning 2 points for at least 50% symptomatic stenosis on carotid or intracranial imaging (0.69, 95% CI 0.57-0.81, and 0.63, 95% CI 0.51-0.69, respectively). When we evaluated each component of all clinical scores using Cox regression analyses, we observed that prior TIA and LAA were independent predictors of stroke recurrence at the 7-day follow-up [hazard ratio (HR) 3.97, 95% CI 1.91-8.26, p < 0.001, and HR 3.11, 95% CI 1.47-6.58, p = 0.003, respectively] and 90-day follow-up (HR 2.35, 95% CI 1.28-4.31, p = 0.006, and HR 2.20, 95% CI 1.15-4.21, p = 0.018, respectively). CONCLUSION: All published scores that do not take into account vascular imaging or prior TIA when identifying stroke risk after TIA failed to predict risk when applied by neurologists. Clinical scores were not able to replace extensive emergent diagnostic evaluations such as vascular imaging, and they should take into account unstable patients with recent prior transient episodes.

Ketoacidosis at onset of type 1 diabetes mellitus in pediatric age in Spain and review of the literature.

UNLABELLED: DKA at diagnosis of T1DM is a life-threatening situation that represents the main cause of morbidity and mortality in pediatric patients with T1DM. OBJECTIVE: To determine whether the occurrence and severity of DKA at diagnosis of T1DM has suffered any changes in recent years in the Spanish paediatric population. PATIENTS AND METHODS: Data from 1169 patients with T1DM under 15 years of age was retrospectively studied (2004 -2008) for the presence and severity of DKA at the onset of T1DM, and compared to previous available studies in Spain. This study is multicentric, nationwide with eleven major Paediatric Diabetes Units involved. RESULTS: Complete data were available from 1151 patients (98%). Frequency of DKA was 39.5%, which is not significantly different from previous Spanish studies. 33.8%, children of 0-4.9 years of age, 40.8% aged 5-10.9 and 25.2% aged 11-14.9 years. Mean age of patients with DKA was significantly lower than the one of patients without DKA (7.44 +/- 4.10 versus 8.47 +/- 3.63 years). Mild DKA was occurring more frequently than moderate and severe forms (47.8%, versus 34.4% versus 17.8%, p<0.0001). Incidence of severe DKA was significantly higher in children under 4.9 years of age, especially in those younger than 2 years (p<0.001). Severe DKA led to complications in three children (cerebral oedema [n=1]), cerebral infarction (n=1) and femoral vein thrombosis (n=1). CONCLUSION: Frequency of DKA at diagnosis of T1DM in Spain is still high although most cases were mild. Children under 2 years of age seem to be at increased risk for severe DKA.

Guidelines for the preventive treatment of ischaemic stroke and TIA (I). Update on risk factors and life style.

OBJECTIVE: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and transient ischaemic attack (TIA). METHODS: We reviewed available evidence on risk factors and means of modifying them to prevent ischaemic stroke and TIA. Levels of evidence and recommendation grades are based on the classification of the Centre for Evidence-Based Medicine. RESULTS: This first section summarises the recommendations for action on the following factors: blood pressure, diabetes, lipids, tobacco and alcohol consumption, diet and physical activity, cardio-embolic diseases, asymptomatic carotid stenosis, hormone replacement therapy and contraceptives, hyperhomocysteinemia, prothrombotic states and sleep apnea syndrome. CONCLUSIONS: Changes in lifestyle and pharmacological treatment for hypertension, diabetes mellitus and dyslipidemia, according to criteria of primary and secondary prevention, are recommended for preventing ischemic stroke.

Early treatment of obstructive apnoea and stroke outcome: a randomised controlled trial.

The aim of the present study was to assess the impact of nasal continuous positive airway pressure (nCPAP) in ischaemic stroke patients followed for 2 yrs. Stroke patients with an apnoea-hypopnoea index ≥ 20 events·h⁻¹ were randomised to early nCPAP (n = 71; 3-6 days after stroke onset) or conventional treatment (n = 69). The Barthel Index, Canadian Scale, Rankin Scale and Short Form-36 were measured at baseline, and at 1, 3, 12 and 24 months. The percentage of patients with neurological improvement 1 month after stroke was significantly higher in the nCPAP group (Rankin scale 90.9 versus 56.3% (p < 0.01); Canadian scale 88.2 versus 72.7% (p < 0.05)). The mean time until the appearance of cardiovascular events was longer in the nCPAP group (14.9 versus 7.9 months; p = 0.044), although cardiovascular event-free survival after 24 months was similar in both groups. The cardiovascular mortality rate was 0% in the nCPAP group and 4.3% in the control group (p = 0.161). Early use of nCPAP seems to accelerate neurological recovery and to delay the appearance of cardiovascular events, although an improvement in patients' survival or quality of life was not shown.

In-hospital stroke: a multi-centre prospective registry.

BACKGROUND: in-hospital strokes (IHS) are relatively frequent. Avoidable delays in neurological assessment have been demonstrated. We study the clinical characteristics, neurological care and mortality of IHS. METHODS: multi-centre 1-year prospective study of IHS in 13 hospitals. Demographic and clinical characteristics, admission diagnosis, quality of care, thrombolytic therapy and mortality were recorded. RESULTS: we included 273 IHS patients [156 men; 210 ischaemic strokes (IS), 37 transient ischaemic attacks (TIA) and 26 cerebral haemorrhages]. Mean age was 72 ± 12 years. Cardiac sources of embolism were present in 138 (50.5%), withdrawal of antithrombotic drugs in 77 (28%) and active cancers in 35 (12.8%). Cardioembolic stroke was the most common subtype of IS (50%). Reasons for admission were programmed or urgent surgery in 70 (25%), cardiac diseases in 50 (18%), TIA or stroke in 30 (11%) and other medical illnesses in 71 (26%). Fifty-two per cent of patients were evaluated by a neurologist within 3 h of stroke onset. Thirty-three patients received treatment with tPA (15.7%). Thirty-one patients (14.7%) could not be treated because of a delay in contacting the neurologist. During hospitalization, 50 patients (18.4%) died, 41 of them because of the stroke or its complications. CONCLUSIONS: cardioembolic IS was the most frequent subtype of stroke. Cardiac sources of embolism, active cancers and withdrawal of antithrombotic drugs constituted special risk factors for IHS. A significant proportion of patients were treated with thrombolysis. However, delays in contacting the neurologist excluded a similar proportion of patients from treatment. IHS mortality was high, mostly because of stroke.

The influence of smoking on bacterial resistance after vaccine or antibiotic prophylaxis against recurrent urinary tract infections. / Influencia del tabaquismo en la resistencia bacteriana después de la profilaxis frente a infecciones urinarias recurrentes con antibiótico o con vacuna.

INTRODUCTION: The influence of tobacco on the microbiological spectrum, resistance-sensitivity pattern and evolution in patients with recurrent urinary tract infections (RUTI) is analyzed. Evaluation of the effect of polyvalent bacterial vaccine on the prevention of RUTI and smoking status. MATERIAL AND METHODS: Retrospective multicenter study of 855 women with RUTI receiving suppressive antibiotic treatment or bacterial vaccine between 2009 and 2013. Group A (GA): Antibiotic (n=495); Subgroups: GA1 non-smoker (n=417), GA2 smoker (n=78). Group B (GB): Vaccine (n=360); Subgroups: GB1 non-smoker (n=263), GB2 smoker (n=97). VARIABLES: Age, pre-treatment UTI, disease-free time (DFT), microbial species, sensitivity and resistance. Follow-up at 3, 6 and 12 months with culture and SF-36 questionnaire. RESULTS: Mean age 56.51 years (18-75), similar between groups (P=.2257). No difference in the number of pretreatment UTIs (P=.1329) or in the distribution of the bacterial spectrum (P=.7471). DFT was higher in subgroups B compared with A. Urine cultures in GA1: E. coli 62.71% with 8.10% resistance (33% quinolones; 33% cotrimoxazole; 33% quinolones + cotrimoxazole); in GA2 E. coli 61.53% with 75% resistance (16.66% quinolones; 33.33% quinolones + cotrimoxazole; 16.66% amoxicillin-clavulanate; 16.66% erythromycin + phosphomycin + clindamycin) (P=.0133). There were no differences between patients of GA treated with cotrimoxazole and nitrofurantoin (P=.8724). Urine cultures in GB1: E. coli 47.36% with 22.22% resistance (5.55% ciprofloxacin; 5.55% cotrimoxazole; 5.55% ciprofloxacin + cotrimoxazole; 5.55% amoxicillin/clavulanic acid). In GB2 E. coli 70.02% with 61.90% resistances (30.76% quinolones; 30.76% cotrimoxazole; 30.76% quinolones + cotrimoxazole; 17.69% amoxicillin-clavulanic acid) (P=.0144). CONCLUSIONS: The development of bacterial resistance is more frequent among women with smoking habits and recurrent urinary infections. This could influence a worse response to preventive treatments, either with antibiotics or vaccines.

Effect of butyl benzyl phthalate on early postnatal mortality in rats.

ABSTRACT The present study was undertaken to examine early postnatal mortality in rat pups following exposure to butyl benzyl phthalate (BBP) during pregnancy. Seventeen pregnant rats were given 750 mg/kg bw/day of BBP by oral gavage on gestation days 13, 14, and 15, and the volume of each dose was adjusted to 5 ml/kg body weight. Four rats were given olive oil only and served as control. Natural birth was allowed to take place. One hundred and eighty-three pups were born to the experimental rats and 46 pups to the control group. Close observation of the newborn pups during the first 3 h of life revealed that all the pups in both the control and experimental groups were born alive. Only six pups from the experimental group (3.2%) died within this time period. These and four control pups were fixed and decalcified. Histological examination of the thoracic cavity of the newborn rats in both groups revealed no differences in the position or size of any of the heart chambers, ductus arteriosus, or great vessels. However, the lungs of the six experimental pups that died showed athelectasia and bronchi dilatation. The results therefore suggest that exposure to BBP of rats during pregnancy does not produce significant postnatal mortality in their offspring.

[Neonatal diabetes mellitus and KCNJ11 gene mutation: report of a family case]. / Diabetes mellitus neonatal y mutación del gen KCNJ11: presentación de un caso familiar.

Neonatal diabetes mellitus (NDM) is characterized by hyperglycemia within the first month of life and insulin dependence for at least two weeks. There are two types of NDM, transient (TNDM) and permanent (PNDM), which are genetically different. We report the case of two brothers who developed hyperglycemia without ketosis on the 18th day and 2 h of life, respectively. Thyroid function tests, abdominal ultrasound and karyotype where normal and there were no pancreatic antibodies. The first one required insulin therapy for the first 92 days of life and the second for 5 months. The mother developed gestational diabetes during both pregnancies and she was later diagnosed diabetes mellitus (without antibodies). They were studied for mutations in KCNJ11 gene (principally related to the permanent form). The three of them showed the E229K mutation (frequently associated with the transient form). A genetic study is essential in NDM to achieve the most accurate prognosis possible.

Seropositivity to a major allergen of Anisakis simplex, Ani s 1, in dyspeptic patients with Helicobacter pylori infection: histological and laboratory findings and clinical significance.

Previous studies have demonstrated a high prevalence of seropositivity to the Ani s 1 protein in dyspeptic patients with Helicobacter pylori infection, but it is not known whether this represents episodes of anisakiasis misdiagnosis or previous exposure to the parasite without clinical relevance. To investigate the clinical significance of seropositivity to the Ani s 1 protein, a cohort study was performed with 87 consecutive dyspeptic patients who were treated for H. pylori infection. Fourteen (16.5%) patients were seropositive for the Ani s 1 protein, which was associated with the consumption of uncooked fish (p 0.0002). There were no differences in histological findings between subjects seropositive or seronegative for Ani s 1, but seropositive patients had increased eosinophil and basophil leukocyte counts (p < 0.05). Anti-Ani s 1 IgE was associated with a lack of improvement in the group of patients with non-ulcer dyspepsia after successful eradication of H. pylori (p 0.016). Thus, in at least a subset of patients with H. pylori infection, seropositivity to Ani s 1 could have clinical relevance. In addition, these data highlight that only anisakiasis associated with severe allergic or gastric symptoms is currently being diagnosed.

[Congenital hyperinsulinism. Review of 22 cases]. / Hiperinsulinismo congénito. Revisión de 22 casos.

INTRODUCTION: Congenital hyperinsulinism (CHI) is the most common cause of recurrent episodes of hypoglycemia in early childhood and consists of a group of distinct genetic disorders causing dysregulation of insulin secretion. OBJECTIVE: To review the presentation, management and outcome of patients with CHI attended at our hospital. MATERIAL AND METHODS: A retrospective review of all patients diagnosed with CHI between 1982 and 2004 was performed. Data were collected on age, gender, clinical presentation, medical and surgical management, and complications. RESULTS: Twenty-two patients were identified. Notable features were early symptom onset in 80 %, pancreatectomy in 72 %, and neurological sequels in 28 % (abnormal neurodevelopment in 22 % and epilepsy in 13 %). CONCLUSIONS: The presentation, management and outcome in our patients were similar to those in other series, indicating the need for early diagnosis and treatment to avoid neurological sequels.

[AIRE gene mutation in polyglandular syndrome type 1]. / Mutación del gen AIRE en el síndrome poliglandular tipo I.

Autoimmune polyglandular syndrome type 1 (APS-1) is an autosomal recessive disorder characterized by chronic mucocutaneous candidiasis, autoimmune hypoparathyroidism, and primary adrenal insufficiency. It has recently been associated with mutations of a single gene found on chromosome 21, designated AutoImmune Regulator (AIRE). We report two patients with APS-1 referred to our hospital for evaluation. The first patient was an 11-year-old girl with hypoparathyroidism, infectious or immunological malabsorption, and autoimmune hepatitis. Hypoparathyroidism associated with other processes with a probable autoimmune origin suggested APS-1. Genetic study was performed revealing deletion of 13 base pairs in exon 8 of the AIRE gene. The second patient was a 17-year-old girl with autoimmune hepatitis, hypoparathyroidism, mucocutaneous candidiasis, nail dystrophy, and obliterating bronchiolitis with a probable autoimmune origin. We suspected APS-1 and genetic study was performed. The only finding was an AIRE gene polymorphism. In conclusion, the presence of a single disease criterion is sufficient to suspect APS-1 and to indicate genetic study. Further studies are required to confirm the involvement of other genes in the development of this disease.

[Macroorchidism: a case report]. / Macroorquidismo: a propósito de un caso.

Macroorchidism is a rare condition in children and is usually associated with fragile X syndrome. Other possible etiologies of macroorchidism are long-standing primary hypothyroidism, adrenal remnants in congenital adrenal hyperplasia, follicle stimulating hormone (FSH)-secreting pituitary macroadenomas, local tumors, lymphomas, and aromatase deficiency. Bilateral macroorchidism can be a normal variant in adult men. We report the case of an 11.5-year-old boy who was referred to our hospital for evaluation of marked bilateral testicular enlargement in the previous few months. Physical examination revealed a testicular volume larger than 30 ml. Complementary investigations allowed us to rule out all hitherto reported etiologies of bilateral macroorchidism and therefore a diagnosis of idiopathic macroorchidism was established. The increased number of Sertoli cells found on biopsy, without elevated plasma FSH levels, prompted us to speculate about a hypothetical FSH receptor hyperfunction as a possible cause of the exaggerated testicular enlargement in this patient.
