Frequency of food intake by adolescent schoolchildren in Cantabria, Spain. Comparison with the consensus document: Food Guidelines for the Spanish Population

OBJECTIVE: To analyze food consumption patterns among schoolchildren in Cantabria and to compare results obtained with Spanish food guidelines for this population group. METHODS: A food frequency questionnaire was the chosen method, with some 53 food types divided into 15 groups. A total of 1,205 teenagers of both sexes aged between 14 and 18 attending 18 secondary schools in Cantabria completed the questionnaire. RESULTS: Milk, bread, fruit, greens and vegetables are the foodstuffs mostly consumed at the recommended frequencies. On the other hand, fish, meat, eggs, dairy products and pulse make up the least adequately consumed categories. Alcoholic drinks are imbibed to a high degree, with beer being the alcoholic most frequently drunk. Spirits are also drunk in larger quantities than wine. Alcohol consumption (beer, wines and spirits) increases significantly with age, being higher among males than females. CONCLUSIONS: Cantabrian schoolchildren follow a food consumption pattern which, generally speaking, does not tally with Spanish food recommendations for their age group. Educational and interventional strategies need to be developed with the aim of modifying such inappropriate food consumption.

Type I familial amyloid polyneuropathy and pontine haemorrhage

A Portuguese female, aged 47 years, who had emigrated to Spain, was admitted to the hospital in 1991 for pontine haematoma. The patient, four siblings and her father were affected by a peripheral neuropathy, indicating autosomal dominant inheritance. The patient presented in the 2nd decade with sensory and motor neuropathy beginning in the lower extremities. Alternating constipation and diarrhoea, and urinary incontinence became uncontrollable. She had to be colostomised, and, eventually, confined to a wheelchair from the age of 43. Neurological examination showed bilateral facial involvement, and severe signs of sensory and motor peripheral neuropathy, and later right hemiplegia. There were abnormalities of atrial rhythm and left bundle branch block. Computerised axial tomography and magnetic resonance images demonstrated left-sided pontine haemorrhage. Nerve conduction studies revealed severe diminution of motor conduction velocity and absence or reduction of amplitude of sensory and motor action potentials. Inanition and a respiratory infection led to her death. Clinical diagnosis was type I familial amyloid polyneuropathy (FAP). Postmortem examination demonstrated amyloid deposits in peripheral nerves, including spinal roots and cranial nerves, leptomeninges, thyroid, breasts, heart, adrenal glands, kidneys, intestines, pancreas, and meningeal and some pontine vascular structures. Advanced pontine haematoma was verified. Cerebral haemorrhage usually occurs with cerebrovascular amyloidosis, but exceptionally with FAP. A minority of patients presenting with CNS haemorrhage showed arteriovenous malformation or embolism [Da Silva Horta and Dias Coelho (1960) Arch de Vecchi Anal Patol Med Clin 31=163–172]. However, amyloid deposition in some small pontine vessels could have played a role in the pathogenesis of haemorrhage in the present case.     

Utility of the sickness impact profile in Parkinson's disease.

The Sickness Impact Profile (SIP) is a questionnaire consisting of 136 items grouped into 12 categories and two dimensions (physical and psychosocial). To characterize its utility in Parkinson's disease (PD), we administered the SIP to 44 consecutive clinic patients with PD. Compared to 44 age- and sex-matched control subjects, PD patients had their greatest dysfunction in the categories of mobility, communication, and home management. The two items that PD patients most commonly endorsed were, "I am having trouble writing or typing" (75%) and, "My sexual activity is decreased" (61%). In general, these treated PD patients had greater dysfunction in the psychosocial than physical dimensions. Two simple PD-specific scales correlated well with the physical dimension score but less so with the psychosocial dimension, suggesting that the SIP assesses more functional domains than the PD-specific scales used. The SIP holds some promise as a broad measure of functional status in PD patients.     

Attentional set shifting modulates the target P3b response in the Wisconsin card sorting test

For years the Wisconsin card sorting test (WCST) has been used as a test of frontal lobe function. Recent event-related potential (ERP) research has shown large differences in the amplitude of P3b responses evoked by early and late trials within each WCST series ([8]: Barceló F., Sanz M., Molina V., Rubia FJ. The Wisconsin Card Sorting Test and the assessment of frontal function: A validation study with event-related potentials. Neuropsychologia 1997;35:399-408). In this study, 16 normal subjects performed a WCST adaptation to investigate the role of attentional set shifting in these WCST P3b effects. Two control tasks were designed to examine whether early-late WCST P3b changes reflect category selection (attention) or category storage (memory) operations. Results suggest both a sharp P3b attenuation during shift WCST trials, followed by a gradual P3b build-up during post-shift trials. This P3b modulation could not be attributed to selection or storage of simple sensory stimulus dimensions, nor was it observed when the new rule was externally prompted by the first card in the WCST series. Instead, WCST P3b changes seem related to the endogenously generated shift in the perceptual rule used to sort the cards (i.e., the shift in set). The gradual build-up in P3b amplitude paralleled a progressive improvement in sorting efficiency over several post-shift WCST trials. A model based on formal theories of visual attention and attentional set shifting is proposed to account for these effects. The model offers firm grounds for prediction and bridges the gap between related clinical and experimental evidence.

Pelvic lipomatosis: clinical review and report of 4 new cases

First described by the end of the fifties, pelvic lipomatosis is an uncommon disease that develops as a result of an excessive proliferation of benign fat tissue within the perivesical and perirectal spaces. The compressive effect on the urinary, and to a lesser degree, the digestive and vascular structures result in the well-known symptoms. Diagnosis is reached through X-ray studies, primarily computerised tomography. Contribution of four new cases in young males diagnosed through imaging studies as well as biopsies in three of them. Evolution has been varying, with medical control of symptoms in two cases and renal function impairment due to upper obstructive uropathy in the other two.     

Analysis of anti-reflux surgery failure

Recurrent gastroesophageal reflux following fundoplication is a challenging problem, because it is usually refractory to medical treatment and a second, technically difficult, antireflux operation is required. Different factors that may contribute to surgery failure have been identified in children. We present 8 cases who underwent redofundoplication after failed procedures, from a total number of 96 patients operated on due to gastroesophageal reflux. Four patient's had their initial fundoplication performed at our institution. Six patients were neurologically impaired, six had chronic pulmonary disease, and two had esophageal atresia. The main presenting symptoms were recurrent vomiting (n = 8) and aspiration (n = 4). Gastroesophageal reflux was confirmed by barium swallow and endoscopy. Operative findings showed wrap breakdown in two cases, warp breakdown associated with hiatal hernia in five, wrap breakdown associated with paraesophageal hernia in two cases, and paraesophageal hernia with normal wrap in one. A second Nissen procedure were performed in five cases, whereas a Collis-Nissen gastroplasty was realized in three with a short esophagus. Six patients had a successful outcome remaining symptom free, one has severe disphagia, and one has recurrent vomiting. In our experience, patients with recurrent gastroesophageal reflux disease should undergo an antireflux procedure tailored to specific anatomic or functional abnormalities.     

Progressive acquired lymphangioma: report of a case and review of the literature

We present 2-year-old patient with a allopecia lesions in scalp, and clinique diagnostic of Cutis Aplasia. The anatomopathologic study have diagnosed the lesions as Acquired Progressive Lymphangioma (APL). Is a rare vascular tumour that has a tendency to appear in childhood an to progress slowly over the years. It could present as a solitary erythematous macule or plaque and a simple excision is usually curative. Our patient is the youngest reported in the literature.
