Endonasal approaches to the sellar and parasellar regions: Closure techniques using biomaterials
Purpose: We reviewed the clinical outcomes resulting from various closure techniques used following endoscopic endonasal surgery for lesions in the sellar and parasellar regions. We compared our current closure technique, which uses a biological matrix of native equine collagen (TissuDura) fixed with fibrin sealant (Tisseel), with the technique we employed previously, using autologous materials, in order to assess the comparative efficacy and tolerability of both methods over the medium- to long-term. Methods: A review was conducted of all cases of endonasal endoscopic intervention carried out in our institution between 1997 and 2007. Operations performed between January 1st 1997 and December 31st 2003 involved a sellar closure technique using autologous materials, either alone or supported by fibrin sealant. From January 1st 2004, sellar reconstruction techniques involving resorbable heterologous materials were used in the closure phases. Post-operatively, clinico-endoscopic assessments took place at 15 days, 1, 3, and 6 months and yearly thereafter, supplemented by magnetic resonance imaging (MRI) scanning at 3 months and annually. Results: Between January 1st 1997 and December 31st 2003, 79 operations were performed in which the sellar closure technique involved the use of autologous materials. Between January 1st 2004 and January 1st 2008, 125 operations were performed in which biomaterials were used for sellar closure. The incidence of complications (fluid fistula) was 2.5% in the autologous materials closure group and 1.6% in the biomaterials closure group. The most marked difference between the two approaches was seen at 1-month follow-up, when restoration of mucociliary transport in the sphenoidal sinus and physiological functionality of the nasal mucosa and paranasal sinuses were observed to be superior in the biomaterials patient cohort. Conclusions: The development of biomaterials for closure of the sellar floor offers a viable alternative to traditional techniques using autologous materials. \ua9 2009 Springer-Verlag

Helicobacter pylori infection in asymptomatic elderly subjects living at home or in a nursing home: effects on gastric function and nutritional status
Age and close living conditions are known to be risk factors for the acquisition of Helicobacter pylori (HP) infection. It is unknown whether institutionalization of asymptomatic, elderly subjects is an additional risk factor and whether gastric function and nutritional status are affected by the HP infection. The study sample comprised 102 subjects over 65 years of age: 52 living in a nursing home and 50 at home. No subject had symptoms or previous pathology related to the upper digestive tract. In all subjects, serum levels of specific anti-HP antibodies were determined. Gastric function was evaluated by levels of pepsinogen A (PGA), pepsinogen C (PGC) and gastrin. The nutritional status of the subject was evaluated by measuring: albumin, haemoglobin, iron, ferritin, transferrin, vitamin B12, and folic acid in blood, and body mass index and mid-arm muscle area. The prevalence of anti-HP antibodies was 86.5% in institutionalized subjects (men: 100%; women:76.6%, p <0.05) and 82.0% in subjects living at home (men:86.3%; women:76.3%). No differences between the two groups were observed in levels of serum anti-HP antibodies and PGC was identified. In neither group were differences observed between serum positive (HP + ve) and negative (HP - ve) subjects with respect to the biohumoral and anthropometric indices of nutritional status. We conclude: (1) the seroprevalence of the HP infection was high (82-86%) in asymptomatic elderly patients living either at home or in an institution; (2) the presence of specific IgG anti-HP antibodies in asymptomatic elderly individuals, at home or in a nursing home, was not associated with changes in PGA levels in institutionalized subjects; (3) nutritional indices were not influenced by the presence of anti-HP antibodies
