Parasitic mites are the major threat to the Western honey bee, Apis mellifera L. For much of the world, Varroa destructor Anderson & Trueman single-handedly inflicts unsurmountable problems to A. mellifera beekeeping. However, A. mellifera in Asia is also faced with another genus of destructive parasitic mite, Tropilaelaps. The life history of these two parasitic mites is very similar, and both have the same food requirements (i.e., hemolymph of developing brood). Hence, parasitism by Tropilaelaps spp., especially Tropilaelaps mercedesae and Tropilaelaps clareae, also results in death of immature brood or wing deformities in infested adult bees...

The renal condition referred to as focal segmental glomerulosclerosis (FSGS) presents a diagnostic dilemma for the clinician. It encompasses and displays a nonspecific histologic appearance on a kidney biopsy specimen, rather than a unique disease entity. This characteristic of FSGS often makes treatment decisions and prognostication difficult. A 34-year-old man, who was born with ambiguous genitalia, had received a diagnosis of FSGS in young adulthood and now had advanced kidney disease. He underwent genetic testing to determine whether a genetic disorder was underlying his kidney disease and to ascertain his risk of FSGS recurrence if he were to receive a kidney transplant...

The increasing incidence of request for medical services to support gender transition for children, adolescents and adults has consequences for society, governmental institutions, schools, families, health care professionals, and, of course, patients. The sociological momentum to recognize and accommodate to trans phenomena has posed ethical dilemmas for endocrinologists, mental health professionals and sexual specialists as they experience within themselves the clash between Respect for Patient Autonomy, Beneficence, Nonmalficience, and Informed Consent...

In 2009 contract dental care was introduced into Sweden's Public Dental Service under a programme called Dental Care for Health (DCH). Previous research has revealed a possible dilemma whereby dental care professionals had the role of insurance agent foisted upon them, as they were assigned the task of 'selling contracts'. Using qualitative interviews, this study explores how these professionals make sense of contract dental care today. Drawing on the concepts of occupational and organisational professionalism, in combination with the institutional logics perspective, we discern that dental care professionals are entangled in multiple rationalities when reasoning about and dealing with DCH...

Guidance recommends 'back to sleep' positioning for infants from birth in order to reduce the risk of sudden infant death. Exceptions have been made for babies with severe respiratory difficulties where lateral positioning may be recommended, although uncertainty exists for other conditions affecting the upper airway structures, such as cleft palate. This paper presents research of (i) current advice on sleep positioning provided to parents of infants with cleft palate in the UK; and (ii) decision making by clinical nurse specialists when advising parents of infants with cleft palate...

Identifying the etiology of chronic diarrhoea might be challenging in some patients, and before a diagnosis is made these patients may spend a substantial length of time with unresolved symptoms leading to uncertainty and anxiety that is severely impairing their life quality. A 45-year-old female was referred by her general practitioner with a 5-year history of increasingly frequent episodes of cyclical diarrhoea, vomiting, abdominal pain and intermittent palpitations. Contrast CT Abdomen/Pelvis revealed a 36x33x46 mm mass in the aorto caval region of her retro-peritoneum, just above the bifurcation...

Since the initial description of tropical pyomyositis 130 years ago, this disease continues to retain some mystery for physicians and surgeons. The infrequency, variable epidemiologic and demographic profile, diagnostic dilemmas and limited literature continue to make it an enigma with limited understanding. In the span of nearly 130 years, worldwide English literature search has revealed an average of only two to three reported cases every year globally. We recently managed a case of tropical pyomyositis which posed a clinical and radiologic diagnostic dilemma...

BACKGROUND Heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication of heparin administration. It can present a major clinical dilemma for physicians caring for patients requiring life-saving urgent or emergent cardiac surgery. Studies have been published examining the use of alternative anticoagulants for patients undergoing cardiopulmonary bypass (CPB), however, evidence does not clearly support any particular approach. Presently, there are no large-scale, prospective randomized studies examining the impact of alternative anticoagulants on clinical outcomes for HIT-positive patients requiring cardiac surgery...

How does cognitive sophistication impact cooperation? We explore this question using a model of the co-evolution of cooperation and cognition. In our model, agents confront social dilemmas and coordination games, and make decisions using intuition or deliberation. Intuition is automatic and effortless, but relatively (although not necessarily completely) insensitive to context. Deliberation, conversely, is costly but relatively (although not necessarily perfectly) sensitive to context. We find that regardless of the sensitivity of intuition and imperfection of deliberation, deliberating undermines cooperation in social dilemmas, whereas deliberating can increase cooperation in coordination games if intuition is sufficiently sensitive...

A thyroid ultrasound examination program has been conducted in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident to address concerns about the increased risk of thyroid cancer similar to those experienced by local residents after the 1986 Chernobyl accident. This is the second-largest thyroid cancer screening in younger age ever, following only that conducted after Chernobyl. As the natural history of thyroid cancer in younger populations is not well characterized, large-scale screening using thyroid ultrasound could result in overdiagnosis, even with careful planning, as has been experienced in South Korea...

BACKGROUND: Management of ruptured arteriovenous malformations (AVMs) with a mass-producing intracerebral hematoma (ICH) represents a surgical dilemma. OBJECTIVE: To evaluate the clinical outcome and obliteration rates of microsurgical resection of AVM when performed concomitantly with evacuation of an associated space-occupying ICH. METHODS: Data of patients with AVM were collected prospectively. Cases were identified in which an AVM was resected and an associated space-occupying ICH was evacuated at the same time, and divided into "group 1," in which the surgery was performed acutely within 48 h of presentation (secondary to elevated intracranial pressure); and "group 2," in which selected patients were operated upon in the presence of a liquefying ICH in the "subacute" stage...

BACKGROUND: Patients with groin, hip and pelvic pain but normal findings on MRI and minimal changes on x-ray can be a diagnostic problem. This paper looks at the arthroscopic findings of patients who have had hip pain and a positive response to an intra-articular anaesthetic but have non-contributory imaging. We hypothesized that standard MRI's were missing significant pathology and if there was a response to intra-articular local anaesthesia, pathology found during arthroscopy was likely...

The decision on how to treat tubal diseases, specifically hydrosalpinx, is a difficult one. Ιt involves surgical, medical, social, emotional and economic factors. This narrative review aims to increase awareness of tubal disease diagnosis and treatment, to compare between tubal surgery and in vitro fertilisation (IVF) for tubal factor infertility, and to investigate the effect of the combination of both. This way, we can be more effective, safe and provide our patients with better treatment results. The review analysed randomised studies, trials and meta-analysis, which give new aspects on the treatment methods for tubal pathology before IVF...

The moral permissibility of harm is strikingly varied among individuals. In light of the connection between testosterone levels and utilitarian moral judgment, this study examined to what extent a CAG polymorphism in the androgen receptor gene, a genetic polymorphism with the ability to regulate testosterone function, contributes to individual differences in moral judgment. Four hundred and thirty-nine Chinese Han participants completed permissibility ratings of harm in moral dilemmas and moral transgression scenarios...

Inspired by the remarkable promotion of power conversion efficiency (PCE), commercial applications of organic photovoltaics (OPVs) can be foreseen in near future. One of the most promising applications is semitransparent (ST) solar cells that can be utilized in value-added applications such as energy-harvesting windows. However, the single-junction STOPVs utilizing fullerene acceptors show relatively low PCEs of 4%-6% due to the limited sunlight absorption because it is a dilemma that more photons need to be harvested in UV-vis-near-infrared (NIR) region to generate high photocurrent, which leads to the significant reduction of device transparency...

BACKGROUND: Lymphoproliferative disease often presents the clinician and pathologist with a diagnostic dilemma, particularly in the early course of the disease. METHODS: We used modified BIOMED-2 protocols to detect monoclonal expansions of immunoglobulin heavy chain (IgH) and T-cell receptor (TCR) genes in 957 formalin-fixed paraffin-embedded samples from 717 patients. To eliminate false-positive results, heteroduplex analysis was used after PCR reactions. The impact of different fixatives on DNA quality and performance of PCR was assessed...

Today more men work in the long-term care sector, but men are still in the minority. Little is known about men's experiences in care work, and the dilemmas and opportunities they face because of their gender. This article focuses on men care workers' integration into the organization and flow of nursing home work as perceived by these workers and staff members. Using a rapid ethnography method in two Ontario nursing homes, we found work organization affected interpretations of gender and race, and that workers' scope for discretion affected the integration and acceptance of men as care workers...

A potential real-time imaging water-soluble fluorescent polymer (P3) is facilely prepared via one-pot method. For P3, tetraphenylethene unit serves as the fluorescent unit, poly(acryloyl ethylene diamine) (a kind of polyelectrolyte) with specific degree of polymerization acts as water-soluble part. (1) H-NMR, gel permeation chromatography (GPC), UV-vis spectroscopy, photoluminescence (PL), and confocal laser scanning microscopy are undertaken to characterize the structure and property of P3. The results of wash-free cellular imaging show that the signal-to-noise ratio is high as the concentration of P3 is 50 μg mL(-1) ...
