In a consensus process during four sessions in 2016, the working group "lower cervical spine" of the German Society for Orthopedic and Trauma Surgery (DGOU), formulated "Therapeutic Recommendations for the Lower Cervical Spine", taking into consideration the current literature. Therapeutic goals are a permanently stable, painless cervical spine and the protection against secondary neurologic damage while retaining the greatest possible amount of motion and spinal profile. Due to its ease of use and its proven good reliability, the AOSpine classification for subaxial cervical injuries should be used...

Juxtapapillary capillary hemangioma (JCH) is a vascular hamartoma. Fluorescein fundus angiography aids in diagnosis. The vascular morphology of this tumor has not been documented with optical coherence tomography angiography (OCTA), a new, noninvasive diagnostic modality that provides high-resolution images of vascular pattern based on blood flow in the retina and choroid. Although mainly a clinical diagnosis, OCTA helps in studying the intrinsic vascularity of the tumor and helps in differentiating it from other vascular tumors...

The identification of signs of awareness in patients with prolonged disorders of consciousness (DoC) after severe brain injury is a challenging task for clinicians. Differentiating on behavioural examination the vegetative state (VS) from the minimally conscious state (MCS) can lead to a high misdiagnosis rate. Advanced neuroimaging and neurophysiological techniques can supplement clinical evaluation by providing physiological evidence of brain activity. However, an open issue remains whether these empirical results are directly or indirectly associated with covert consciousness and limitations emerge for their diagnostic application at the single-patient level...

The aim of the current article is to offer definitive guidance on weaning children who are reliant on nasogastric/gastrostomy feeding tubes. To date, no internationally recognized definitions or principles for interventions exist, and clinics have been reliant on creating their own unique intervention criteria. To achieve the aim, 2 goals are set out within the current article. The first goal was to definitively define the process of tube weaning. To achieve this, both tube dependency and oral eating also required definitions...

STUDY DESIGN: Case Study. BACKGROUND AND PURPOSE: Low back pain is a common condition managed by physical therapists (PT). Screening tools have been developed to assist the PT with medical screening of patients for serious disease. Sinister pathologies may present as musculoskeletal symptoms during the patient examination. It is important for the PT to frequently reevaluate their patient's response to therapeutic interventions and refer for further evaluation if they are not responding to conservative care...

Uninephrectomy is not associated with major adverse events in cardiovascular and renal functions of live kidney donors. The effect of high salt diet on the quality of life of live kidney donors is largely unknown. Hence in this study, we aimed to determine the effect of high salt diet on the alterations of renin-angiotensin system and microRNAs leading to CV and renal dysfunction in uninephrectomized rats. In order to mimic clinical scenario, uninephrectomized male Sprague Dawley rats were fed initially with normal pellet diet for 12 weeks and then for 20 weeks with high salt (10% w/w NaCl) diet...

BACKGROUND: The antiphospholipid syndrome (APS) is defined by simultaneous presence of vascular clinical events and antiphospholipid antibodies (aPL). The aPL considered as diagnostics are lupus anticoagulant and antibodies anticardiolipin (aCL) and anti-ß2 glycoprotein-I (aB2GP1). During recent years, IgA aB2GP1 antibodies have been associated with thrombotic events both in patients positive, and mainly negative for other aPL, however its value as a pro-thrombotic risk-factor in asymptomatic patients has not been well defined...

Microwave imaging is an emerging breast cancer diagnostic technique, which aims at complementing already established methods like mammography, magnetic resonance imaging, and ultrasound. It offers two striking advantages: no-risk for the patient and potential low-cost for national health systems. So far, however, the prototypes developed for validation in labs and clinics used costly lab instruments such as a vector network analyzer (VNA). Moreover, the CPU time required by complex image reconstruction algorithms may not be compatible with the duration of a medical examination...

Microbiological cultures provide essential information to guide the antibiotic therapy. However, their results might be misleading for physicians and drive useless treatment, sometimes harmful for patients. Recommendations highlight the importance of clinical signs in order to take into account the pre-test probability when interpreting the results. This combination will improve the predictive value of microbiological tests. The sampling strategy is also important to avoid an overuse of these tests but also misleading results through a reduction of contaminants...

OBJECTIVES: Diagnosis of pleural tuberculosis (PT) is still a challenge, particularly in resource- constrained settings. Alternative diagnostic tools are needed. We aimed at evaluating the utility of Clinical Prediction Rules (CPRs) for diagnosis of Pleural Tuberculosis (PT) in Peru. METHODS: We identified CPRs for diagnosis of PT through a structured literature search. CPRs using high-complexity tests, as defined by the FDA, were excluded. We applied the identified CPRs to patients with pleural exudates attending two third-level hospitals in Lima, Peru, a setting with high incidence of tuberculosis...

Chronic cutaneous wound infections and surgical site infections (SSIs) present a huge burden on the healthcare system and can lead to increased morbidity and mortality. Current diagnostic methods of identifying and confirming infection involve culture-based and molecular methods. Both techniques are time consuming and delays commonly lead to un-targeted empirical treatment. An ideal diagnostic method would be non-invasive and highly sensitive and detect pathogenic organisms with a high degree of accuracy in order to allow targeted treatment...
