New porcine test-model reveals remarkable differences between algorithms for spectrophotometrical haemoglobin saturation measurements with VLS.

Unlabelled: The study created an 'ex vivo' model to test different algorithms for measurements of mucosal haemoglobin saturation with visible light spectrophotometry (VLS). The model allowed comparison between algorithms, but it also allowed comparison with co-oximetry using a 'gold standard' method. This has not been described before.

Abdominal auscultation does not provide clear clinical diagnoses.

Introduction: Abdominal auscultation is a part of the clinical examination of patients, but the determining factors in bowel sound evaluation are poorly described. The aim of this study was to assess inter- and intra-observer agreement in physicians' evaluation of pitch, intensity and quantity in abdominal auscultation.

Material And Methods: A total of 100 physicians were presented with 20 bowel sound recordings in a blinded set-up.

[Kaposiform haemangioendothelioma in the small intestine of a three year-old boy].

Kaposiform haemangioendothelioma is a rare, locally aggressive vascular tumour, which is mainly found in children. Typically, it occurs in the skin. The tumour is borderline malignant due to its rapid infiltrative growth.

Tissue hypoxaemia causes oedema, inflammation and fibrosis in porcine bronchial transsection.

Objectives: Bronchial artery revascularization in lung transplantation is disputed. This study examined the physiological consequences of porcine bronchial transsection and reanastomosis with and without bronchial artery blood supply with relation to lung transplantation.

Design: Translational, controlled animal study.

[Endoscopic complication: unsuspected impact of gastroscope into the oesophagus in a patient with a large hiatal hernia].

Gastroscopy is used world-wide and it is considered as a safe procedure. In a case study we describe an impaction of a gastroscope into the oesophagus. A gastroscopy in full narcosis was performed on a patient with a large size hiatal hernia.

[A 10-kg ovarian mucinous cystadenoma in a 13 year-old girl].

A 13 year-old girl was admitted to hospital with abdominal pain and weight gain. The physical examination showed pronounced abdominal distension, but slim extremities. A magnetic resonance imaging scan revealed a left cystic ovarian tumour.

[Use of skills among ambulance crews assessed by ambulance on-line record-keeping system].

Introduction: To fulfil the increasing requirements for documentation and quality assurance, amPHI, an ambulance on-line record-keeping system has been developed. We present the data from the pilot study to access how often ambulance crews use their skills.

Materials And Methods: As a pilot study amPHI was installed and tested in an emergency ambulance for 21 months.

Diffuse reflectance spectrophotometry with visible light: comparison of four different methods in a tissue phantom.

The purpose of the study was to compare algorithms of four methods (plus two modifications) for spectrophotometric haemoglobin saturation measurements. Comparison was made in tissue phantoms basically consisting of a phosphate buffer, Intralipid and blood, allowing samples to be taken for reference measurements. Three experimental series were made.

Multi-centre comparison of five eye movement detection algorithms.

Although various investigators have suggested algorithms for the automatic detection of eye movements during sleep, objective comparisons of the proposed methods have previously been difficult due to different recording arrangements of different investigators. In this study the results of five eye movement detection algorithms applied to the same data were compared to visually scored data. The percentages of true and false detections are given for various threshold levels in rapid and slow eye movement detections.
