- The aim of this study was to evaluate a direct and automated post-polymerase chain reaction (PCR) detection system to simultaneously determine the relative gene expression levels of nine cancer-related human genes. Total RNA was prepared from flash-frozen biopsies derived from human colorectal tumors or normal mucosa and reverse-transcribed to cDNA which was PCR-amplified using primer pairs corresponding to the studied genes. In each reaction, the forward primer was labeled with a fluorescent dye. The PCR products were pooled and an internal size standard with a uniquely colored fluorescent dye was added. The samples were then subjected to automated capillary gel electrophoresis. Fragment analysis software was used to calculate the relative gene expression using beta-actin as the reference gene. We found that automated capillary gel electrophoresis with multicolor detection is a rapid, accurate and highly reproducible method for separation and quantification of PCR-amplified cDNA.

- Large paraesophageal hernias are related to life-threatening complications that warrant immediate surgery. Whether the long-standing chronic symptoms related to the disease in individuals without hernia incarceration motivate surgical treatment is still a subject for discussion. The aim of this study was to explore how individuals suffering from Grade II–IV hiatal hernia describe their symptoms and health, as well as how the disease affects their life. Semistructured interviews were performed with 22 individuals planning to undergo surgery for a large paraesophageal hernia. The data were analyzed using qualitative content analysis and resulted in one main theme “Being caught in a vicious circle” and six subthemes “Distressing and uncertain times,” “The symptoms have seized control over my health,” “Loss of energy and strength,” “Strategies for managing daily life,” “Loss of social life,” and “Moments of hope despite failing health.” Central to the participants’ descriptions is their commitment to strategies for managing the ever-present and unpredictable symptoms that have seized control over their health. They were trapped in a hopeless and isolated existence, that is, a vicious circle, from which they were unable to escape. Despite the low incidence of volvulus and incarceration, the symptom burden and effect on general health motivate treatment in these individuals.

- Surgery is the only available treatment for the longstanding chronic symptoms associated with large paraesophageal hernias except for reflux disease. The aim of this study was to illuminate how patients who previously suffered from grade III-IV hiatal hernia experience their life and health 2-6 months after surgery. The study is based on semi-structured interviews with 17 patients who received elective laparoscopic hernia repair for a large paraesophageal hernia. The data were analyzed using qualitative content analysis, resulting in three main themes: "Experiences of health,""Being unable to leave the disease behind,"and "Still feeling unwell"and seven subthemes: "Escaping suffering"; "Learning to interpret bodily signals"; "Looking to the future with confidence"; "Finding oneself in a vicious circle of worry"; "The fear of relapse as a constant companion"; "Lingering disabling symptoms,"and "New and frightening symptoms."Our study demonstrates large individual variations in the way patients experience their life and health after laparoscopic hernia repair. Central to the patients' descriptions is that simply feeling physically healthy is insufficient for achieving overall health. Health care personnel can benefit from learning about patients' experiences of health and suffering after surgery.

- Background: Traumatic brain injury (TBI) is a common cause of morbidity and mortality in children worldwide. In Scandinavia, the epidemiology of pediatric head trauma is poorly documented. This study aimed to investigate and compare the epidemiology and management of pediatric patients with isolated head trauma (IHT) and head trauma in connection with multitrauma (MHT). Methods: We conducted a retrospective review of medical records of patients < 18 years of age who attended any of the five emergency departments (ED) in Scania County in Sweden in 2016 due to head trauma. Clinical data of patients with IHT were analyzed and compared with those of patients with MHT. Results: We identified 5046 pediatric patients with head trauma, 4874 with IHT and 186 with MHT, yielding an incidence of ED visits due to head trauma of 1815/100,000 children/year. There was male predominance, and the median age was four years. Falls were the dominating trauma mechanism in IHT patients, while motor vehicle accidents dominated in MHT patients. The frequencies of CT head-scans, ward admissions and intracranial injuries (ICI) were 5.4%, 11.1% and 0.7%, respectively. Four patients (0.08%) required neurosurgical intervention. The relative risks for CT-scans and admissions to a hospital ward and ICI were 10, 4.5 and 19 times higher for MHT compared with IHT patients. Conclusion: Head trauma is a common cause of ED visits in our study. Head-CTs and ICIs were less frequent than in previous studies. MHT patients had higher rates of CT-scans, admissions, and ICIs than IHT patients, suggesting that they are separate entities that should ideally be managed using different guidelines to optimize the use of CT-scans of the head.

Lead aprons and thyroid collars: to be, or not to be?

Tidskriftsartikel (refereegranskat)abstract
- Wearing lead aprons and thyroid collars for long periods of time has a subjective component: to balance the effective dose reduction with the effort of carrying a heavy load. Occupational radiation exposure has decreased dramatically in the last century within the health care system. During the same period the use of lead aprons and thyroid collars has also gone up. Therefore, a question that may be raised is: how safe is safe enough? In order to promote stakeholder involvement, the aim of the present study was to investigate staff's experience of discomforts associated with wearing lead aprons and thyroid collars for long periods of time, and also to investigate staff's willingness to tolerate personal dose equivalent (expressed as radiation dose) and the corresponding increase in future cancer risk to avoid wearing these protective tools. A questionnaire was developed and given to staff working in operating or angiography rooms at Skaraborg Hospital in Sweden. The results from the 245 respondents showed that 51% experienced bothersome warmth, 36% experienced fatigue and 26% experienced ache or pain that they believed was associated with wearing lead aprons. One third of the respondents would tolerate a personal dose equivalent of 1 mSv per year to avoid wearing lead aprons, but only a fifth would tolerate the corresponding increase in future cancer risk (from 43% to 43.2%). In conclusion, discomforts associated with wearing lead aprons and thyroid collars for long periods of time are common for the staff using them. At the same time, only a minority of the staff would tolerate a small increase in future cancer risk to avoid wearing them. The present study gives an example of stakeholder involvement and points at the difficulties in making reasonable decisions about the use of these protective tools.
