[Home parenteral nutrition in Spain 2011 and 2012; a report of the home and ambulatory artificial nutrition group NADYA]. / Nutrición Parenteral Domiciliaria en España 2011 y 2012: informe del grupo de nutrición artificial domiciliaria y ambulatoria NADYA.

OBJECTIVE: To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the years 2011 and 2012. METHODOLOGY: We compiled the data from the on-line registry introduced by reviewers of NADYA group responsible for monitoring of NPD introduced by since January 1, 2011 to december 31, 2012. Included fields were: age, sex, diagnosis and reason for HPN, access path, complications, beginning and end dates, complementary oral or enteral nutrition, activity level, autonomy degree, product and fungible material supply, withdrawal reason and intestinal transplant indication. RESULTS: Year 2010: 184 patients from 29 hospitals , representing a rate of 3.98 patients/million inhabitants/ year 2011, with 186 episodes were recorded NPD . During 2012, 203 patients from 29 hospitals , representing a rate of 4.39 patients/million inhabitants/year 2012 , a total of 211 episodes were recorded NPD . CONCLUSIONS: We observe an increase in registered patients with respect to previous years.Neoplasia remains as the main pathology since 2003. Although NADYA is consolidated registry and has been indispensable source of information relevant to the understanding of the progress of Home Artificial Nutrition in our country, there is ample room for improvement. Especially that refers to the registration of pediatric patients and the registration of complications.

Objetivo: Comunicar los datos del registro de Nutrición Parenteral Domiciliaria (NPD) del grupo de trabajo NADYA-SENPE de los años 2011 y 2012. Material y métodos: Recopilación de los datos del registro "on-line" introducidos por los colaboradores del grupo NADYA responsables del seguimiento de la NPD desde el 1 de enero de 2011 al 31 de diciembre de 2012 dividido por años naturales. Resultados: Año 2010: Se registraron 184 pacientes, procedentes de 29 hospitales, lo que representa una tasa de 3,98 pacientes/millón habitantes/año 2011, con 186 episodios de NPD. Durante el año 2012 se registraron 203 pacientes, procedentes de 29 hospitales, lo que representa una tasa de 4,39 pacientes/millón habitantes/año 2012, con un total de 211 episodios de NPD. Conclusiones: Se observa un aumento progresivo de los pacientes registrados respecto a años anteriores. El principal grupo patológico sigue siendo oncológico ocupando el primer lugar desde 2003. Aunque el registro NADYA es un registro consolidado y ha sido y es fuente imprescindible de información relevante para el conocimiento de los avances de la Nutrición Artificial Domiciliaria en nuestro país, queda un amplio margen para la mejora. En especial lo que hace referencia al registro de pacientes pediátricos y al registro de las complicaciones.

[Severe hypophosphataemia after starting parenteral nutrition in a patient with an intestinal fistula]. / Hipofosfatemia grave tras el inicio de nutrición parenteral en una paciente con fístula intestinal.

Hypophosphataemia is a complication that may appear in undernourished patients who are given nutrition by either enteral or parenteral means. It is associated with several clinical manifestations, including cardiological, neurological and haematological conditions of note, and may potentially be even life-threatening. It is therefore mandatory to ensure prevention and follow-up in those patients at risk of suffering this condition, taking into account the considerable morbidity and mortality associated with it.

[Acute nutritional problems in the oncology patient]. / Problemas agudos de la nutrición en el paciente oncológico.

Alterations to the nutritional state are frequent in oncology patients. These constitute an important medical problem, with a tendency to rise in recent years. Some tumours usually appear more frequently in persons with prior malnutrition or excessive consumption of alcohol or tobacco. But besides, either because of the disease, or because of the treatment to which they are subjected, it is frequently the case that oncology patients show problems of deglutition and require the placement of probes for enteral nutrition. The present paper offers an initial evaluation of the nutritional state of these patients and, subsequently, of the most important problems that patients with enteral nutrition can present in emergencies.

[The proliferating nuclear fraction as a prognostic factor in superficial bladder carcinomas]. / Estudio de la fracción proliferativa nuclear como factor pronóstico en los carcinomas de vejiga superficiales.

OBJECTIVE: Low grade, low stage superficial bladder tumors have, in general, a good prognosis; however, some of these tumors progress and behave more aggressively, displaying a high incidence of recurrence and rapid transformation into a higher grade of malignancy with deep invasion of the bladder wall. Numerous studies have been conducted on markers which help to predict this transformation. METHODS: The expression of the anti-proliferating cell nuclear antigen (PCNA) was examined in bladder specimens from 72 patients with superficial transitional cell carcinoma utilizing the PC10 monoclonal antibody. We have compared expression of PCNA with other markers. The cases were divided into three groups: group A comprised patients with good clinical behaviour; group B comprised patients who developed recurrences of the same histological grade and group C comprised patients with superficial TCC who developed muscle wall invasion within 2 years. RESULTS/CONCLUSIONS: Our results demonstrate that the monoclonal antibody PC10 is an excellent marker for the aggressive, low stage and low grade superficial bladder tumours and can distinguish these from those which have a good clinical behaviour.

Expression of Lewis antigenic determinants in colorectal adenocarcinomas.

Expression of type 1 and type 2 chain Lewis antigens was studied in 32 rectal adenocarcinoma specimens; the results were correlated with the patients' Lewis phenotype and secretor status. In addition, the pattern of expression of these antigens was analyzed in adjacent and distant normal mucosa. We used an indirect immunofluorescence technique with p-phenylenediamine counterstaining (Oriol technique) and a panel of monoclonal antibodies directed against the different antigenic specificities. Normal distal colonic mucosa only expresses monofucosylated structures (Lea and X) arising from activity of the alpha 1-3,4-fucosyltransferase coded by the Le gene. Rectal adenocarcinomas also show Lea and X, but also reexpress blood group antigens ABH and exhibit difucosylated determinants (Leb and Y). The accumulation of mono- and difucosylated type 2 chain in neoplastic processes, independently of the Le and Se genes, could be due to the enzymes coded by reactivation of the H and X genes. Blood group antigens form a complex signal code, genetically regulated, which intervenes in differentiation, growth and cellular recognition processes, and which may undergo important modifications during malignant transformation. These alterations could be useful in the diagnosis and prognosis of some types of carcinoma.
