Follow-up after curative surgery for colorectal carcinoma - Randomized comparison with no follow-up

PURPOSE: This study investigated the value of intense follow-up compared with no follow-up after curative surgery of cancer in the colon or rectum. METHODS: One hundred seven patients were randomized to no follow-up (control group; n=54) or intense follow-up (follow-up group; n=53) after surgery and early postoperative colonoscopy. Patients in the follow-up group were followed at frequent interval

Accuracy of ct arterial portography of the liver compared with findings at laparotomy

To evaluate the accuracy of CT arterial portography (CTAP) of the liver, CTAP examinations from 111 patients were retrospectively reviewed and compared with the findings at laparotomy. Laparotomy had been performed within 3 weeks after the CTAP examination. In cases of resectable liver tumor, the result from the pathologic examination report was used to calculate the accuracy of CTAP. In cases of

Detection of hepatic metastases in colorectal cancer : A prospective study of laboratory and imaging methods

Objective: To assess and compare the accuracy of imaging methods (ultrasonography (US), computed tomography (CT), angiography, arterially enhanced CT with computed tomographic arterial portography (CTA)), biochemical analyses, and surgical assessment during the operation, in detecting the presence or absence of hepatic metastases in patients with colorectal cancer. Design: Open study. Setting: Uni

Interstitial laser thermotherapy of a rat liver adenocarcinoma

The aim of this study was to compare interstitial laser thermotherapy with excision of a liver tumour. A dimethylhydrazine-induced adenocarcinoma was implanted into the left lateral lobe of the rat liver, and treatment was performed 8 days later. Rats were treated with resection of the tumour-bearing lobe or underwent interstitial laser thermotherapy, which was performed at a steady-state temperat

The Initial Development of Voice Onset Time in Early Successive French-Swedish Bilinguals

This chapter explores the initial development of VOT in three Swedish-speaking learners of French (age of onset: 3;0-3;5). Swedish uses long lag and short lag/lead to differentiate voiceless and voiced stops word-initially (Helgasson & Ringen 2008; Sundberg & Lacerda 1999). In French this distinction is made using short lag and lead (Kessinger och Blumstein 1997). Through a memory game wor

The middle ear immune defense changes with age

Otitis media is a common disease in childhood. In adults, the disease is relatively rare, but more frequently associated with complications. Possible reasons for this discrepancy are age-related differences in pathogen exposure, anatomy of the Eustachian tube and immune system. The objective of this study was to analyze the relationship between age and the mucosal immune system in the middle ear.

Airway inflammation in chronic rhinosinusitis with nasal polyps and asthma : The united airways concept further supported

Background: It has been established that patients with chronic rhinosinusitis with nasal polyps (CRSwNP) often have co-existing asthma. Objective: We aimed to test two hypotheses: (i) upper and lower airway inflammation in CRSwNP is uniform in agreement with the united airways concept; and (ii) bronchial inflammation exists in all CRSwNP patients irrespective of clinical asthma status. Methods: We

Differential gene expression in the otic capsule and the middle ear - An annotation of bone-related signaling genes

Hypothesis: A number of bone-related genes may be responsible for the unique suppression of perilabyrinthine bone remodeling. Background: Bone remodeling is highly inhibited around the inner ear space most likely because of osteoprotegerin (OPG), which is a well-known potent inhibitor of osteoclast formation and function. However, other signaling molecules may also be responsible for the inhibitio

Gene expression of the endolymphatic sac

Conclusion: The endolymphatic sac is part of the membranous inner ear and is thought to play a role in the fluid homeostasis and immune defense of the inner ear; however, the exact function of the endolymphatic sac is not fully known. Many of the detected mRNAs in this study suggest that the endolymphatic sac has multiple and diverse functions in the inner ear. Objectives:The objective of this stu

A re-evaluation of the concept of type in coroplastic studies based on 3D shape analysis of terracotta figurines from Ayia Irini, Cyprus

Coroplastic studies refer to the study of terracotta figurines mostly through an art history ap-proach, where types and classes are defined through stylistic and aesthetic considerations. Such an approach is highly subjective and is based on the knowledge of the researcher interacting with the subject material. Moreover, the lack of agreed upon criteria for classification and the lack of quantitat

Bone signaling in middle ear development : a genome-wide differential expression analysis

Common middle ear diseases may affect bone behavior in the middle ear air cell system. To understand this pathologic pneumatization, the normal development of bone in the middle ear should be investigated. The objective of this study was to analyze gene expression of bone-related signaling factors and gene sets in the developing middle ear. Microarray technology was used to identify bone-related g

Kosmiskt Ljus

Titta upp nattetid. Du ser stjärnor och stjärnbilder, månen och kanske några planeter. Men det finns mycket mer därute. Vårt universum är enormt och vi behöver stora teleskop, både markbaserade och rymdbaserade, för att observera det. Teleskop kan visa oss avlägsna galaxer, nebulosor och det ljus som våra ögon inte kan registrera. Med deras hjälp upptäcker vi hur nya stjärnor bildas, utvecklas ochLook up at night. You will see stars and constellations, the Moon and maybe even a few planets. But there is more out there.Our Universe is huge and we need large telescopes, both ground based and space based, to observe it. Telescopes can show us distant galaxies, nebulae and the light that our eyes can not register. With their help we discover how stars are born, how they evolve and explode. Wit

Stjärnor och galaxer

I denna planetariumvisning får våra besökare träffa en astronom från institutionen för astronomi och teoretisk fysik som berättar om hur vi har kommit fram till det vi vet om Universum idag.Har du någonsin undrat om hur vi mäter avståndet till avlägsna stjärnor och galaxer? Hur stjärnorna bildas, utvecklas och exploderar? Undrar du om det finns liv i universum? Hur stort Universum är? Hur vi nu haIn this planetariumshow our visitors get to meet an astronomer from Lund Observatory who explains not only what we know about our Universe, but also how we know what we know. Have you ever wondered how we measure distances to stars and galaxies? How new stars are formed, how they evolve and why they explode? Do you wonder if there is life out there? How big our Universe is? How we have now discove
