Prospective assessment of postoperative pain after craniotomy.
2010
Pain after craniotomy may be underdiagnosed, despite the fact that it can increase postoperative complications for example arterial hypertension and postoperative hemorrhage. This study investigates the incidence and intensity of pain after craniotomy and characterizes the influencing parameters. During a 1-year period 256 patients undergoing elective craniotomy were prospectively included in the study. Intensity of pain was evaluated 1, 4, and 24 hours after extubation using a verbal numerical rating scale (NRS) ranging from 0 (no pain) to 10 (maximal pain). Routine perioperative pain management was not influenced by the investigators. Parameters including patient-related factors, drug adm…
NDST1 missense mutations in autosomal recessive intellectual disability.
2014
NDST1 was recently proposed as a candidate gene for autosomal recessive intellectual disability in two families. It encodes a bifunctional GlcNAc N-deacetylase/N-sulfotransferase with important functions in heparan sulfate biosynthesis. In mice, Ndst1 is crucial for embryonic development and homozygous null mutations are perinatally lethal. We now report on two additional unrelated families with homozygous missense NDST1 mutations. All mutations described to date predict the substitution of conserved amino acids in the sulfotransferase domain, and mutation modeling predicts drastic alterations in the local protein conformation. Comparing the four families, we noticed significant overlap in …
Changes in anatomic position of root canal orifices in pluriradicular teeth following re-location during endodontic treatment
2017
Abstract Direct access to the root canals in posterior teeth for endodontic treatment is most frequently facilitated by the straightening of the coronal parts of the root canals, having as a consequence the relocation of the canal orifices on the map of the floor of the pulp chamber ( Christie and Thompson, 1994 ). This procedure intentionally moves the coronal aspect of a canal away from the center of the chamber, while simultaneously removing internal dentin from the pulp chamber walls. The aim of this study was to evaluate the displacement resulting from the relocation of root canal orifices during the initial phase of rotary root canal treatment in molars using the dental operating micr…
Intrathecal somatic hypermutation of IgM in multiple sclerosis and neuroinflammation
2014
Intrathecal oligoclonal bands of the cerebrospinal fluid are considered the most important immunological biomarkers of multiple sclerosis. They typically consist of clonally expanded IgG antibodies that underwent affinity maturation during sustained stimulation by largely unknown antigens. In addition, ∼40% of patients with multiple sclerosis have oligoclonal bands that consist of expanded IgM antibodies. We investigated the molecular composition of IgM- and IgG-chains from cerebrospinal fluid of 12 patients with multiple sclerosis, seven patients with other neurological diseases, and eight healthy control subjects by high-throughput deep-sequencing and single-cell PCR. Further, we studied …
Differences and Similarities between Allergic and Nonallergic Rhinitis in a Large Sample of Adult Patients with Rhinitis Symptoms
2010
<i>Background:</i> Allergic rhinitis (AR) and nonallergic rhinitis (NAR) may present with different clinical and laboratory characteristics. <i>Methods:</i> A total of 1,511 consecutive patients, aged 18–81 years, diagnosed with rhinitis, 56% females and 44% males, underwent complete allergic evaluation including skin prick test, blood eosinophil counts, nasal eosinophil counts, peak nasal inspiratory flow (PNIF) measurement and evaluation of nasal symptoms using a visual analog scale (VAS). <i>Results:</i> A total of 1,107 patients (73%)had AR, whereas 404 (27%) had NAR. Patients with NAR were older and predominantly female. A higher nasal eosinophils co…
Comparison of olfactory function in patients with seasonal and perennial allergic rhinitis
1998
Hyposmia is a common symptom in allergic rhinitis. However, little is known about differences in the olfactory function of patients with seasonal or perennial allergy. A prospective controlled study was performed on 28 patients with allergic rhinitis to grass pollen and on 47 patients with allergic rhinitis to mites. Sixty-six healthy volunteers served as a control. Olfactory function was evaluated by a modified Connecticut Chemosensory Clinical Research Center testing procedure for threshold, identification, and discrimination. The grass pollen-allergic patients were tested preseasonally and after 3 weeks of intraseasonal grass pollen exposure; the mite-allergic patients and the volunteers…
Increased expression of IL-19 in the epithelium of patients with chronic rhinosinusitis and nasal polyps.
2012
Background : Chronic rhinosinusitis (CRS) is an inflammation of the nose and of the paranasal sinuses. The involvement of the respiratory epithelium in the mechanisms of CRS is poorly understood. Aims : Among proteins expressed by nasal epithelial cells in CRS, IL-19 may have key functions. We here aimed to determine the expression and regulation of IL-19. Methods : Nasal biopsies from normal subjects (n = 12), subjects with CRS but without nasal polyps (NP) (CRSsNP, n = 12) and with CRS with NP (CRSwNP, n = 15) were collected. Human Asthma Gene Array and real-time PCR were used to evaluate gene expression, western blot analysis and immunohistochemistry for protein expression. Results for I…
Low SPINK5 expression in chronic rhinosinusitis
2012
Objectives/Hypothesis: Chronic rhinosinusitis (CRS) is a multifactorial disease that probably arises as a result of genetic diversity and environmental factors. SPINK5 is a serine protease inhibitor, which is supposed to be an important regulator of epithelial barrier maintenance. The role of SPINK5 polymorphisms and expression in CRS, especially in individuals with aspirin intolerance, is unclear. Study Design: SPINK5 single-nucleotide polymorphisms (SNPs) and SPINK5 expression levels were correlated with CRS without (CRSsNP) and with nasal polyps (CRSwNP), aspirin intolerance, asthma, and allergies. Methods: One hundred four nasal tissue samples, 15 from patients with CRSsNP, 59 from pati…
Ophthalmic Outcomes of Congenital Toxoplasmosis Followed Until Adolescence
2014
BACKGROUND: Congenital toxoplasmosis (CT) can elicit severe damage to several organs, especially the eye, and may be manifested at birth or later. We assessed the long-term ocular prognosis in a cohort of congenitally infected children treated according to a standardized protocol and monitored for up to 22 years. METHODS: This prospective study included confirmed cases of CT, which were identified by obligatory antenatal screening at the Lyon (France) reference center between 1987 and 2008. Data obtained through ocular examinations were recorded on a standardized form and confirmed by an independent external committee. Risk factors for retinochoroiditis were identified by using a multivari…
Local administration of antisense phosphorothioate oligonucleotides to the p65 subunit of NF-kappa B abrogates established experimental colitis in mi…
1996
Chronic intestinal inflammation induced by 2,4,6,-trinitrobenzene sulfonic acid (TNBS) is characterized by a transmural granulomatous colitis that mimics some characteristics of human Crohn's disease. Here, we show that the transcription factor NF-kappa B p65 was strongly activated in TNBS-induced colitis and in colitis of interleukin-10-deficient mice. Local administration of p65 antisense phosphorothioate oligonucleotides abrogated clinical and histological signs of colitis and was more effective in treating TNBS-induced colitis than single or daily administration of glucocorticoids. The data provide direct evidence for the central importance of p65 in chronic intestinal inflammation and …
