Implementation and Evaluation of Educational Workshops to Increase Primary Care Provider and Medical Student Comfort in Psychiatric Care.

OBJECTIVE: Mental health treatment is often initiated in primary care settings, but many primary care providers (PCPs), residents, and medical students report discomfort in managing psychiatric conditions. This study evaluated the effect of an educational workshop that featured an evidence-based psychopharmacology clinical decision support tool (CDST) on trainee confidence and willingness to treat psychiatric conditions. METHODS: Participants completed pre- and post-workshop surveys. Nine months after the workshop, a subset of trainees participated in a focus group. RESULTS: Of the participants, 62.5% of the obstetrics-gynecology (OB-GYN) resident physicians (10/16) and 100% of the medical students (18/18) completed both pre- and post-surveys. Following the workshop, OB-GYN resident physicians reported significantly improved confidence in treating psychiatric disorders (p < 0.001), sense of having psychiatric support tools (p < 0.001), and knowledge of treating psychiatric disorders (p = 0.021). Medical students reported significantly improved confidence in treating psychiatric disorders (p < 0.001), willingness to devise treatment plans for psychiatric disorders (p = 0.024), sense of having psychiatric support tools (p < 0.001), knowledge of treating psychiatric disorders (p < 0.001), and comfort in presenting a psychiatric treatment plan to an attending (p = 0.003). Most focus group participants (93.75%; 15/16) reported that they continued to use the CDST, and it increased their confidence in formulating psychiatric treatment plans. CONCLUSIONS: These findings suggest that educational workshops that introduce high-quality psychopharmacology CDSTs may be an effective method for improving provider comfort in treating psychiatric disorders.

Conservative Nonsurgical Approach for Management of a Case of Type II Dens in Dente.

Dens in dente is a developmental dental anomaly which poses a challenge for the endodontist due to its complex pulpal anatomy. In this case report, a class 2 dens in dente was managed nonsurgically. A 32-year-old female reported with a palatal swelling and pain in the upper front region of the jaw. On examination, #7 was observed to be malformed and showed a negative pulpal sensibility test. Radiographic and CBCT analysis revealed Ohler's type 2 dens in dente with a periapical radiolucency. In the first visit, invagination was removed using diamond-coated ultrasonic tips, the canal was minimally instrumented, and premixed calcium hydroxide was injected in the canal which accidentally extruded periapically. After two weeks, a draining sinus was observed on the palatal side which when traced, lead to #7. Intracanal dressing was replaced with a mix of powdered calcium hydroxide and saline. The dressing was replaced every two weeks, and radiographs were taken, which revealed the resorption of extruded calcium hydroxide and reduction in the osseous defect. Biodentine was used to obturate the entire canal space. Subsequent follow-up radiographs till 24 months showed significant periapical healing and resorption of extruded calcium hydroxide.

Left main stem stenosis angioplasty with intravascular ultrasound optimisation criteria guidance using a new generation everolimus drug-eluting stent.

INTRODUCTION: Intravascular ultrasound (IVUS) is recommended in the use of left main stem (LMS) percutaneous coronary intervention (PCI). Since the LMS diameter is usually larger than other coronary arteries, a new generation everolimus drug-eluting stent (DES), Synergy Megatron DES (Boston Scientific) has better axial and radial strength allowing more post implant overexpansion and consequently better suited for LMS lesions. We performed a study to evaluate the clinical outcomes of PCI using 1) an improved IVUS protocol with optimisation targets and 2) the use of Megatron stents. MATERIALS AND METHODS: This was a study involving LMS PCI coronary lesions using the Synergy Megatron DES. An IVUS protocol using predefined optimisation targets to evaluate for stent malapposition, longitudinal stent deformation, optimal stent expansion >90% of reference lumen and appropriate distal landing zone was used in all cases. The primary end-point was procedural success, defined by successful stent implantation with <30% residual stenosis. The secondary end-point was in-hospital and 30-day major adverse cardiovascular event (MACE). RESULTS: Eight patients with significant LMS stenosis were successfully treated with the Megatron stent. The primary end-point was achieved in all patients. There were no cases of stent malapposition or longitudinal stent deformation, one case did not have optimal LMS stent expansion and one case did not have an appropriate distal landing zone. IVUS optimisation criteria were met in 6 (75%) cases. There were no complications of coronary dissection, slow or no reflow, stent thrombosis or vessel perforation. None of the patients suffered in-hospital or 30-day MACE. The average LMS MLD at baseline was 2.1 ± 0.1mm and the post-PCI LMS MLD was 4.0 ± 0.5mm, with a significant acute luminal gain of 1.9 ± 0.7mm (p<0.01). A post-PCI MSA of 17 ± 3.9 mm2 was numerically superior compared to those documented in other LMS PCI trials. CONCLUSION: This study demonstrates low rates of shortterm major adverse cardiovascular events among patients with LMS PCI using the Megatron stents. It highlights the usefulness of IVUS-guided optimisation in LMS PCI. With the use of intravascular imaging, the new generation stent technology can improve the treatment of large proximal vessels and PCI of LMS lesions.

Intravascular imaging-guided treatment of severe coronary artery calcification with orbital atherectomy: A prospective single-centre registry.

INTRODUCTION: Coronary artery calcification can lead to suboptimal results when performing coronary angioplasty with conventional techniques. The presence of severe coronary artery calcium increases the complications of percutaneous coronary intervention as it may impede stent delivery and optimal stent expansion. The purpose of this study was to determine the procedural success and safety of orbital atherectomy (OA) in calcified lesions. MATERIALS AND METHODS: This was a prospective single-centre study regarding the utility of OA in the treatment of calcified coronaries. Intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was used in all cases to characterise the severity of calcium pre-procedure, guide vessel sizing and assess procedural success. The primary endpoint was procedural success, defined by successful stent implantation following OA treatment. The secondary endpoint was in-hospital and 30-day major adverse cardiovascular event (MACE). RESULTS: Ten patients with severely calcified lesions were successfully treated with OA. The primary endpoint was achieved in all patients. All of the lesions were severely calcified with concentric calcium. None of the patients suffered in-hospital or 30-day MACE. The average minimal luminal diameter at baseline was 1.7 ± 0.3 mm and the post- PCI luminal diameter was 3.0 ± 0.3 mm, with a significant luminal gain of 1.3 ± 0.3 mm (p < 0.01). Slow flow during procedure occurred in 2 (20%) cases and dissection occurred in 1 (10%) case during procedure. These were successfully treated with stent delivery to achieve TIMI III flow. There were no cases of stent thrombosis or vessel perforation. CONCLUSION: Our experience demonstrates the feasibility and safety of OA in the management of calcified coronary stenosis. Intravascular imaging is an important adjunct to the use of OA to assess the severity of calcified coronary lesions, success of OA treatment and to aid sizing of the vessel for stent implantation. OA is an effective treatment approach to disrupt coronary calcification, facilitating stent implantation with optimal results. It is a safe procedure with good success rate and low rate of complications.

Treatment of severe coronary artery calcification with intravascular lithotripsy: Initial experience of a prospective single centre registry.

INTRODUCTION: Coronary artery calcification can lead to suboptimal results when performing coronary angioplasty with conventional techniques. Shockwave intravascular lithotripsy (IVL) has recently been introduced as a new modality to treat heavily calcified coronary arteries. The purpose of this study was to determine the procedural success and safety of IVL in calcified lesions. MATERIALS AND METHODS: This was a prospective single-centre study regarding the utility of IVL in treatment of calcified coronary arteries. Intravascular ultrasound (IVUS) was used in all cases to characterise the lesions pre procedure and to assess procedural success post procedure. The primary end point was procedural success, defined by IVL treatment and successful stent implantation. The secondary end point was in-hospital and 30-day major adverse cardiovascular event (MACE). RESULTS: Five patients with severely calcified lesions were successfully treated with IVL. The primary end point was achieved in all patients. All of the lesions were severely calcified with concentric calcium. Multiple calcium fractures were identified on IVUS after IVL in all cases. None of the patients suffered in-hospital or 30-day MACE. The average diameter stenosis at baseline was 1.8±0.4mm and the post PCI diameter stenosis was 2.9±0.1mm, with significant acute luminal gain of 1.2±0.3mm (p<0.01). There were no complications of coronary dissection, slow or no reflow, stent thrombosis, or vessel perforation. CONCLUSION: Our initial experience demonstrates the feasibility and safety of IVL in the management of calcified coronary stenosis. The shockwave IVL is an effective treatment approach to disrupt coronary calcification, facilitating stent implantation with optimal results. It is a safe procedure with a good success rate and low rate of complications.

Pediatric Dental Surgery Under General Anesthesia: Uncooperative Children.

Dental treatment of young pediatric patients can be confounded by lack of cooperation for dental rehabilitation procedures and even examination and/or radiographs. With the recent US Food and Drug Administration warning applied to many anesthetic/sedative agents for children less than 3 years old, a retrospective review of general anesthesia (GA) cases from 1 private pediatric dental practice was studied for age, gender, body mass index, anesthetic duration, airway management used, extent of dental surgical treatment, recovery time, and cardiac/pulmonary complications. For the 2016 calendar year, 351 consecutive GA cases were identified with patients aged 2-13 years. Of these, 336 underwent nasal endotracheal intubation. Forty-six of 351 patients (13%) were younger than 3 years. Median anesthesia duration was approximately 1.7 hours for all age groups. Dental treatment consisting of 8-9 teeth including crowns, fillings, and extractions was most frequently encountered. One hundred sixty-eight patients (48%), however, required care for 10-18 teeth. There were no episodes of significant oxygen desaturation. The overall complication rate was 1.1%, with 2 cases of postextubation croup, 1 case of mild intraoperative bronchospasm, and 1 case of intraoperative bradycardia. Complications did not correlate with children being overweight or obese.

Disaster Coverage Predication for the Emerging Tethered Balloon Technology: Capability for Preparedness, Detection, Mitigation, and Response.

OBJECTIVE: A disaster is a consequence of natural hazards and terrorist acts, which have significant potential to disrupt the entire wireless communication infrastructure. Therefore, the essential rescue squads and recovery operations during a catastrophic event will be severely debilitated. To provide efficient communication services, and to reduce casualty mortality and morbidity during the catastrophic events, we proposed the Tethered Balloon technology for disaster preparedness, detection, mitigation, and recovery assessment. METHODS: The proposed Tethered Balloon is applicable to any type of disaster except for storms. The Tethered Balloon is being actively researched and developed as a simple solution to improve the performance of rescues, facilities, and services of emergency medical communication in the disaster area. The most important requirement for rescue and relief teams during or after the disaster is a high quality of service of delivery communication services to save people's lives. RESULTS: Using our proposed technology, we report that the Tethered Balloon has a large disaster coverage area. Therefore, the rescue and research teams are given higher priority, and their performance significantly improved in the particular coverage area. CONCLUSIONS: Tethered Balloon features made it suitable for disaster preparedness, mitigation, and recovery. The performance of rescue and relief teams was effective and efficient before and after the disaster as well as can be continued to coordinate the relief teams until disaster recovery.

Night of the living thrips: an unusual outbreak of Thysanoptera dermatitis.

Identifying the etiology of a cutaneous eruption in the setting of an acute cluster outbreak is of utmost importance due to the inherent potential public health impact. The differential diagnosis ranges from innocuous arthropod bites to more concerning causes such as infection, medication reaction, and environmental exposure. We report the simultaneous presentation of 15 US Marines who presented with numerous discrete papular skin eruptions. Subsequent thorough patient evaluation and history, literature review, immunization status reconciliation, entomological assessment, site survey, and skin biopsy were performed. This case series is one of the largest reported to date of a cluster outbreak of a papular dermatitis secondary to bites from thrips (ie, insects of the order Thysanoptera).

Pharmacokinetics, pharmacodynamics and adverse event profile of GSK2256294, a novel soluble epoxide hydrolase inhibitor.

AIMS: Endothelial-derived epoxyeicosatrienoic acids may regulate vascular tone and are metabolized by soluble epoxide hydrolase enzymes (sEH). GSK2256294 is a potent and selective sEH inhibitor that was tested in two phase I studies. METHODS: Single escalating doses of GSK2256294 2-20 mg or placebo were administered in a randomized crossover design to healthy male subjects or obese smokers. Once daily doses of 6 or 18 mg or placebo were administered for 14 days to obese smokers. Data were collected on safety, pharmacokinetics, sEH enzyme inhibition and blood biomarkers. Single doses of GSK2256294 10 mg were also administered to healthy younger males or healthy elderly males and females with and without food. Data on safety, pharmacokinetics and biliary metabolites were collected. RESULTS: GSK2256294 was well-tolerated with no serious adverse events (AEs) attributable to the drug. The most frequent AEs were headache and contact dermatitis. Plasma concentrations of GSK2256294 increased with single doses, with a half-life averaging 25-43 h. There was no significant effect of age, food or gender on pharmacokinetic parameters. Inhibition of sEH enzyme activity was dose-dependent, from an average of 41.9% on 2 mg (95% confidence interval [CI] -51.8, 77.7) to 99.8% on 20 mg (95% CI 99.3, 100.0) and sustained for up to 24 h. There were no significant changes in serum VEGF or plasma fibrinogen. CONCLUSIONS: GSK2256294 was well-tolerated and demonstrated sustained inhibition of sEH enzyme activity. These data support further investigation in patients with endothelial dysfunction or abnormal tissue repair, such as diabetes, wound healing or COPD.

Lupus erythematosus tumidus: a unique disease entity.

Lupus erythematosus tumidus (LET) is a photosensitive skin disease characterized by succulent, edematous, and non-scarring plaques. Histologic features include perivascular and periadnexal lymphocytic infiltration and interstitial mucin deposition. Despite being first described in 1909, there are few case reports in the current literature describing this disease and even fewer that discuss treatment. We describe a case of a 22-year-old woman with systemic lupus erythematosus (SLE) and secondary class V lupus nephritis. She was referred to Dermatology for an intermittent pruritic facial eruption that was clinically and histologically consistent with LET. There is much controversy in literature as to whether or not LET is a unique variant of cutaneous lupus erythematosus. Interestingly, the mainstay of treatment for LET, in the limited case reports and series that exist, is with antimalarial drugs, which our patient had already been taking for SLE. This case exemplifies the need for complete disease characterization, evidence-based treatment, and a multidisciplinary approach.

Drug Reaction with Eosinophilia and Systemic Symptoms: DRESS following Initiation of Oxcarbazepine with Elevated Human Herpesvirus-6 Titer.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare and potentially fatal severe cutaneous reaction, which has a delayed onset after the initiation of an inciting medication. After recognition and withdrawal of the causative agent, along with aggressive management, a majority of patients will have complete recovery over several months. We present a rare case of DRESS secondary to oxcarbazepine with an elevated human herpesvirus-6 titer.

ENLIGHT and LEIR biomedical facility.

Particle therapy (including protons and carbon ions) allows a highly conformal treatment of deep-seated tumours with good accuracy and minimal dose to surrounding tissues, compared to conventional radiotherapy using X-rays. Following impressive results from early phase trials, over the last decades particle therapy in Europe has made considerable progress in terms of new institutes dedicated to charged particle therapy in several countries. Particle therapy is a multidisciplinary subject that involves physicists, biologists, radio-oncologists, engineers and computer scientists. The European Network for Light Ion Hadron Therapy (ENLIGHT) was created in response to the growing needs of the European community to coordinate such efforts. A number of treatment centres are already operational and treating patients across Europe, including two dual ion (protons and carbon ions) centres in Heidelberg (the pioneer in Europe) and Pavia. However, much more research needs to be carried out and beamtime is limited. Hence there is a strong interest from the biomedical research community to have a facility with greater access to relevant beamtime. Such a facility would facilitate research in radiobiology and the development of more accurate techniques of dosimetry and imaging. The Low Energy Ion Ring (LEIR) accelerator at CERN presents such an opportunity, and relies partly on CERN's existing infrastructure. The ENLIGHT network, European Commission projects under the ENLIGHT umbrella and the future biomedical facility are discussed.

Mycobacterium haemophilum Masquerading as Leprosy in a Renal Transplant Patient.

Opportunistic infections following immunosuppression in solid organ transplant (SOT) patients are common complications with the skin being a common sight of infection. Nontuberculous mycobacteria (NTM) are rare but potential causes of skin infection in SOT patients. We present a case of an adult male immunosuppressed following renal transplantation who presented with an asymptomatic rash for several months. The patient's skin eruption consisted of erythematous papules and plaques coalescing into an annular formation. After failure of the initial empiric therapy, a punch biopsy was performed that demonstrated nerve involvement suspicious for Mycobacterium leprae. However, culture of the biopsy specimen grew acid-fast bacilli that were subsequently identified as M. haemophilum. His rash improved after a prolonged course of clarithromycin and ciprofloxacin. Both organisms are potential causes of opportunistic skin infections and can be difficult to distinguish with similar predilection for skin and other biochemical and genetic similarities. Ultimately they can be distinguished with culture as M. haemophilum will grow in culture and M. leprae will not. This case was unique due to nerve involvement on biopsy which is classically seen on biopsies of leprosy.

A comparative evaluation of healing with a computed tomography scan of bilateral periapical lesions treated with and without the use of platelet-rich plasma.

Periradicular surgery aims to achieve complete wound healing and regeneration of the periodontal unit. Platelet-rich plasma (PRP) is a platelet concentrate that is widely used to promote tissue healing, and bone induction through its various growth factors has been used in this study. This case report describes the use of PRP unilaterally in a bilateral periapical lesion in the same patient. The site treated with PRP showed better healing than the untreated site. This was confirmed with computed tomography (CT) scan readings. It was hypothesized that PRP could promote tissue regeneration and alveolar bone repair.

Conventional, emerging, heredity, lifestyle, and psychosocial coronary risk factors: relationships to subclinical atherosclerosis.

The authors examined the relationship between calcified coronary atherosclerosis and an array of cardiovascular risk factors in sequential logistic models to determine the extent to which these markers overlap in their identification of patients at risk for developing coronary heart disease. The prevalence of coronary artery calcium using electron beam computed tomography was 19.4% in this cross-sectional study of a prospective, consecutive, screening cohort of 1999 healthy United States Army personnel (aged 39-50 years). The proportion of the total variance of coronary artery calcium explained by sequential logistic models incorporating conventional, emerging, hereditary, lifestyle, and psychosocial cardiovascular risk variables increased progressively from 9.7% to 14.5%. The best-fit logistic model for the prediction of coronary artery calcium identified age, male gender, Framingham risk score, total cholesterol, high-density lipoprotein cholesterol, triglycerides, smoking, a family history of coronary heart disease, white race, physical inactivity, and lower depression scores as significant independent correlates of coronary artery calcium. These data indicate that the explanatory power of models for atherosclerosis can be significantly improved with the use of emerging, heredity, lifestyle, and psychosocial factors. The large residual variance, however, supports the potential of atherosclerosis imaging to incrementally and independently identify coronary heart disease risk.
