This study has analyzed sex-specific differences in pedestrian and cyclist accidents involving passenger cars. The most frequently injured body regions, types of injuries, which show sex-specific differences and the general accident parameters of females and males were compared. Accident data from three different European countries (Austria, Netherlands, Sweden) were analyzed.

Background And Objectives: Operative laparoscopy is generally performed under general anesthesia. Local anesthesia and conscious sedation may be useful in select short procedures. In the present study, we evaluated safety and efficacy of operative laparoscopy under conscious sedation.

Article Synopsis
  • The scientific community's interest in computer-aided skin lesion analysis has grown due to the increasing rates of melanoma, emphasizing the need for early detection to improve survival rates.
  • Accurate diagnosis of skin lesions is challenging and relies heavily on a physician's experience, making the development of computer methods for lesion detail extraction crucial in assisting dermatologists.
  • This paper presents an automatic segmentation method for pigmented skin lesions from dermoscopic images, demonstrating high effectiveness even with irregular boundaries and noise, validated through quantitative evaluation on a public dataset.

As bicyclists account for the largest share of serious injuries in Sweden, focus to improve safety for bicyclists is needed. While knowledge about fatal bicycle crashes is rather extensive, the number of studies that have investigated non-fatal injuries is still rather limited. The aim of this study was to estimate the potential of different countermeasures to reduce crashes resulting in injuries with high risk of health-loss among cyclists in Sweden.

Background: Melioidosis is difficult to diagnose clinically and culture of Burkholderia pseudomallei is the current, imperfect gold standard. However, a reliable point-of-care test (POCT) could enable earlier treatment and improve outcomes.

Methods: We evaluated the sensitivity and specificity of the Active Melioidosis Detect™ (AMD) rapid test as a POCT and determined how much it reduced the time to diagnosis compared with culture.

We have retrospectively reviewed 137 medical records of patients older than 50 years receiving an allogeneic hematopoietic stem cell transplantation (HSCT) between January 1997 and July 2013. Median follow up was 1.3 years.

Introduction: Conscious sedation has traditionally been used for laparoscopic tubal ligation. General anesthesia with endotracheal intubation may be associated with side effects, such as nausea, vomiting, cough, and dizziness, whereas sedation offers the advantage of having the patient awake and breathing spontaneously. Until now, only diagnostic laparoscopy and minor surgical procedures have been performed in patients under conscious sedation.

The superior vena cava syndrome (SVCS) is considered an emergency and requires immediate treatment; therefore, the etiologic diagnosis is essential before deciding on its implementation. The management of SVCS consists on the relief of symptoms and treatment of the underlying disease, aiming to restore the blood flow. We present a 5 years old boy with a history of B-cell ALL.

Background: Clotting activation and thromboembolic manifestations are common features in patients with cancer. Tumor cells can directly activate the clotting through two procoagulants: tissue factor (TF) and cancer procoagulant (CP).

Aims: The aim was to evaluate the levels of TF and CP in patients with different tumors in order to: (1) establish an association between these markers and the tumor localization, (2) establish a correlation between the levels of procoagulants and the status of the disease, (3) evaluate if the treatment with chemotherapy induced some modifications on the levels of procoagulants, (4) evaluate the possibility of using procoagulants as predictors in the development of thrombosis.

Up to 1% of all pregnancies have clinically overt intra-amniotic bacterial infections, and an even larger percentage of pregnant women may be affected by silent infections. Although most pregnant women with overt intra-amniotic bacterial infection have experienced prolonged rupture of membranes (PROM), symptomatic and most silent nonviral intra-amniotic infections may occur with intact membranes. The etiology of intra-amniotic infection after PROM is almost always polymicrobial and consists of genital tract pathogens, such as group B streptococci, Chlamydia trachomatis, Neisseria gonorrhoeae, mycoplasmas, aerobic Gram-negative bacilli, such as the coliforms, and facultative and anaerobic endogenous organisms, such as peptococci, peptostreptococci, and Bacteroides species.

Diagnosis of fetal infection has depended on identification of pathogens by means of microbiological cultures, immunologic techniques, and special molecular biology techniques that can identify organisms known or suspected of being associated with adverse outcomes of pregnancy. Rubella, cytomegalovirus (CMV), herpes simplex virus (HSV), and human immunodeficiency virus (HIV), for example, are capable of gaining access to the amniotic cavity and producing fetal infection, even when amniotic membranes are intact. Intrauterine invasion by viruses can be associated with maternal symptoms of infection or can be completely silent.
