[Prehospital chest tube placement: Which factors are associated with feeling confident to perform the procedure?].

Background: The prehospital placement of chest tubes is a rare but potentially life-saving procedure. A high level of subjective confidence with the procedure is essential for emergency medical doctors. This study aims to identify if there is a statistically significant difference in the subjective sense of confidence in prehospital chest tube placement regarding medical experience and qualification, clinical routine, and attendance at simulation courses.

Optimal Roving Winding on Toroidal Parts of Composite Frames.

Frames made of polymer composites are increasingly used in the aerospace, automotive, and agricultural industries. A frequently used technology in the production line of composite frames is winding rovings onto a non-load-bearing frame to form the structure using an industrial robot and a winding head, which is solidified through a subsequent heat-treatment pressure process. In this technology, the most difficult procedure is the winding of the curved parts of a composite frame.

Coccygectomy in the Treatment of Chronic Coccydynia.

Study Design: This is a retrospective cohort study.

Objective: The aim of this article was to evaluate the results of patients operated for chronic coccydynia, and determine any factors that could affect outcomes.

Summary Of Background Data: Patients with coccydynia who do not respond to conservative treatment will often profit from coccygectomy.

Resection of the coccyx as an outpatient procedure.

We wished to determine if coccygectomy as an outpatient procedure is a safe alternative to inpatient treatment. 68 patients were treated at our institution with coccygectomy as an outpatient procedure during a seven-year period. Out of these 61 (90%) responded to final follow-up questionnaires after a minimum of one year.

The effect of injection therapy and operation of coccydynia on the schooling and physical activity of adolescent patients.

Pain while sitting is the most common complaint among patients with Coccydynia. In young patients this may seriously affect their schooling which usually involves long periods of sitting. We studied if this improved after either injection therapy or surgery.

Corticosteroid injection for coccydynia: a review of 241 patients.

Aims: We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect.

Methods: During 2009 to 2016, we treated 277 patients with chronic coccydynia with either one 6 mg betamethasone or one 20 mg triamcinolone cortisone injection. A susequent injection was given to 62 (26%) of the patients.

The treatment of coccydynia in adolescents: A case-control study.

Aims: To determine if the results of treatment of adolescents with coccydynia are similar to those found in adults. Adult patients with coccydynia may benefit from injection therapy or operative treatment. There is little data evaluating treatment results in adolescents.

Normal Preoperative Images Do Not Indicate a Poor Outcome of Surgery for Coccydynia.

Study Design: This is a retrospective cohort study.

Objective: To evaluate the long-term outcomes after surgery for refractory coccygodynia in patients with normal imaging studies compared with patients where imaging shows an anomaly.

Summary Of Background Data: Patients with coccydynia who do not respond to conservative treatment will often profit from coccygectomy.

OCT Angiography in Young Children with a History of Retinopathy of Prematurity.

Purpose: To describe the size and appearance of the foveal avascular zone (FAZ) in the superficial and deep plexus in young children with treated or spontaneously regressed retinopathy of prematurity (ROP), in comparison with age-matched controls and young adults, as seen with OCT angiography (OCTA), and to compare these parameters with foveal classic OCT images and visual function.

Design: Prospective, cross-sectional study.

Participants: Twenty-five children with treated or spontaneously regressed ROP (mean 5.

Midwives' perception of patient safety culture-A qualitative study.

Objective: To explore midwives' experiences with and perceptions of patient safety culture in the German-speaking countries.

Design And Setting: Semi-structured interviews with midwives were conducted between December 2013 and March 2014, whereby the narrative nature of the questions on patient safety culture provided the space for the interviewed midwives to express their own wishes and thoughts freely. The interviews were recorded and transcribed, and the transcripts were anonymized with respect to personal and institutional names.

Structure-Function Correlation in Hemianopic Vision Loss in Children Aged 3-6 Years Using OCT and SVOP, and Comparison with Adult Eyes.

Purpose: To correlate visual field assessment with saccadic vector optokinetic perimetry (SVOP) in children with ganglion cell loss due to anterior pathway pathologies resulting in hemianopic visual field defects measured with optical coherence tomography (OCT).

Methods: 5 young (aged 3-6 years) and 5 adult patients with hemianopia, 10 healthy preschoolers (mean age 4.4 years), and 10 healthy adults (mean age 25.

[Handheld Optical Coherence Tomography in Paediatric Ophthalmology: Experience of the Department of Ophthalmology in Giessen].

Optical coherence tomography is an important tool for the imaging and analysis of retinal structures. The usability of conventional table-top devices is limited in children. We report on our experiences with a handheld Spectral Domain Optical Coherence Tomography (HH-SD-OCT, Bioptigen™) in infants and young children in our daily practice.

Redirection of doublecortin-positive cell migration by over-expression of the chemokines MCP-1, MIP-1α and GRO-α in the adult rat brain.

Inflammation-induced chemoattraction plays a major role in adult subventricular zone (SVZ)-derived precursor cell migration following neural cell loss, in particular through the release of chemokines by activated microglia and macrophages. We previously demonstrated that monocyte chemotactic protein-1 (MCP-1) (chemokine (c-c motif) ligand (CCL)2), macrophage inflammatory protein-1α (MIP-1α) (CCL3) and growth regulatory protein-α (GRO-α) (chemokine (c-x-c motif) ligand (CXCL)1) are up-regulated following neural cell loss in the adult striatum and act as potent chemoattractants for SVZ-derived precursor cells in vitro. Based on these observations, the current study aimed to examine the individual effect of MCP-1, MIP-1α and GRO-α on the migration of adult SVZ-derived neural precursor cells in vivo.

[Comparison of treatment expenses of naturopathic and orthopedic in-patient treatment].

Background: In health services research comparative studies between orthopaedics and naturopathy are necessary. They allow evidence based decisions between individual therapeutical alternatives as well as decisions on health politics, e.g.

[Early complications in treatment of femoral neck fractures. Experiences with Olmed screws].

Postoperative secondary displacement of displaced femoral neck fractures is a major problem in the treatment of this fracture. In a study of 232 femoral neck fractures operated at the Department of Surgery, Harstad Hospital and at the Departments of Surgery and Orthopaedics, Tromsø University Hospital, the reduction was lost in 12% of the displaced fractures within three months. The fractures were fixated with two 6 mm screws (Olmed).

Endopyelotomy for the management of ureteropelvic junction obstruction.

Endourological advances have given rise to endopyelotomy as a means of correcting ureteropelvic junction obstruction either primary or secondary. Endopyelotomy can be accomplished with a shorter hospital stay and recuperation period as well as less morbidity than open procedures. It seems particularly useful in correcting ureteropelvic junction obstruction associated with renal calculi and failed surgical procedures.

Transcervical resection of submucous uterine fibroids: an alternative approach to management.

Transcervical resection of submucous uterine fibroids can be an effective alternative to laparotomy and transuterine myomectomy in selected women. To date the authors have performed this procedure in three patients in an ambulatory environment. In two patients, transcervical resection was performed for giant intrauterine myomas which caused pathologic uterine bleeding and infertility.
