The use of metals in the medical field has become increasingly prevalent over the past few decades. Patients find themselves being exposed to metals in a variety of ways, ranging from external exposure to instruments such as the stainless steel in surgical blades to internal exposure via medical devices being implanted in their bodies. There has been growing interest in the possibility of developing hypersensitivity reactions to constituent metals in medical implant devices, both in cutaneous and systemic forms...

Importance: Intermittent claudication (IC) is the most common presentation of infrainguinal peripheral artery disease. Both medical and revascularization interventions for IC aim to increase walking comfort and distance, but there is inconclusive evidence of the comparative benefit of revascularization given the possible risk of limb loss. Objective: To compare the effectiveness of a medical (walking program, smoking cessation counseling, and medications) vs revascularization (endovascular or surgical) intervention for IC in the community, focusing on outcomes of greatest importance to patients...

Nucleic acid amplification tests that are coupled with a digital readout enable the absolute quantification of single molecules, even at ultralow concentrations. Digital methods are robust, versatile and compatible with many amplification chemistries including isothermal amplification, making them particularly invaluable to assays that require sensitive detection, such as the quantification of viral load in occult infections or detection of sparse amounts of DNA from forensic samples. A number of microfluidic platforms are being developed for carrying out digital amplification...

In their study published in this issue of Academic Medicine, Costa and colleagues confirmed the underlying constructs of the Interpersonal Reactivity Index (IRI) and the Jefferson Scale of Empathy (JSE) in medical students. The authors of this Commentary propose that in comparing two instruments that both purport to measure empathy, researchers or test users must pay close attention to the target populations, the conceptualizations of empathy, and the validity evidence in relation to pertinent criterion measures...

BACKGROUND: Cluster randomised trials (CRTs) are a key instrument to evaluate public health interventions, particularly in low- and middle-income countries (LMICs). Fidelity assessment examines study processes to gauge whether an intervention was delivered as initially planned. Evaluation of implementation fidelity (IF) is required to establish whether the measured effects of a trial are due to the intervention itself and may be particularly important for CRTs of complex interventions...

BACKGROUND: Fatigue has not been investigated in long-term Intensive Care Unit (ICU) survivors. This study aimed to assess fatigue through a specific instrument, namely the Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) scale, in ICU survivors one year after hospital discharge. A secondary aim was to compare the findings of FACIT-F with those of the Vitality domain (VT) of the 36-item Short-Form Health Survey (SF-36). METHODS: This prospective cohort study was performed on 56 adult patients with a Length Of Stay (LOS) in ICU longer than 72 h...

BACKGROUND: The accessibility of medical care facilities in sparsely populated rural regions is relevant especially for elderly people which often represent a large segment of the population in such regions. Elderly people have higher morbidity risks and a higher demand for medical care. Although travelling with private cars is the dominating traffic mode in rural regions, accessibility by public transport is increasingly important especially because of limited mobility of elderly people...

The orbital aperture is the entrance to the orbit in which most important visual structures such as the eyeball and the optic nerve are found. It is vital not only for the visual system but also for the evaluation and recognition of the face. Eyeball volume is essential for diagnosing microphthalmos or buphthalmos in several eye disorders. Knowing the length of the optic nerve is necessary in selecting the right instruments for enucleation. Therefore, the aim of this study was to evaluate eyeball volume, orbital aperture, and optic nerve dimensions for a morphological description in a Turkish population sample according to gender and body side...

Clinical practice guidelines, which are systematically developed statements aimed at helping people make clinical, policy-related and system-related decisions, frequently vary widely in quality. A strategy is needed to differentiate among guidelines and ensure that those of the highest quality are implemented. Hypertension Canada provides annually updated standardized recommendations and clinical practice guidelines to detect, treat and control hypertension. The annual, evidence-based recommendations are developed through intense discussion of the clinical implications via a systematic review of the literature followed by critical appraisals of all the new clinical research, taking into account the assessment criteria in the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument that evaluates the process of practice guideline development and the quality of reporting...

In December 1913, a board of medical officers was appointed to adapt new U.S. Army equipment to the needs of the Hospital Corps. One of the improvements concerned substitution of the satchel-like Hospital Corps pouch used to carry first aid equipment. A waist belt with 10 pockets, known as the medical belt, was devised, and supplied with a tourniquet, adhesive plaster, safety pins, iodine swabs, sublimated gauze, individual dressing packets, gauze bandages, aromatic spirit of ammonia, and common pins. In addition, an ax carrier accommodating a hand ax, a canteen hanger, and a pouch to carry diagnosis tags and instruments were attached to the medical belt...

The tools described in this article are verified to be Greco-Roman medical and surgical instruments for the eye, ear, nose, and throat. They include three myrtle leaf-shaped scalpels, three ear spoons, a "Q-tip," a forceps, a needle, and two arrow-pointed scalpels. One of the arrow-pointed scalpels is nearly identical to a Juerger keratome, suggesting that in Roman times, cataracts were extracted, not just "couched" into the posterior chamber. The description presented here goes beyond traditional archeological claims, because as a head and neck surgeon, I evaluated these instruments from a surgeon's point of view...
