Restoratively guided orthodontic treatment: The pre-orthodontic bonding concept.

OBJECTIVE: Communication between the orthodontist and the restorative dentist has always been difficult due to the inability of the orthodontist to achieve the desired orthodontic goals with just words in a referral note. CLINICAL CONSIDERATIONS: A better method of communication is for the restorative dentist to create the ideal tooth anatomy either before or during orthodontic treatment to direct the orthodontic tooth movement. CONCLUSION: It is the purpose of this article to present a technique, which makes the pre-restorative orthodontic treatment both more accurate and more efficient. CLINICAL SIGNIFICANCE: It is very difficult for the orthodontist to move teeth into their correct positions when the teeth are anatomically incorrect due to attrition/erosion or due to developmental malformation. When the restorative dentist makes the teeth anatomically correct with either pre-orthodontic or intermediate orthodontic bonding, the orthodontist has the benefit of ideal tooth anatomy to finalize the tooth positions. This then allows the restorative dentist to create final restorations, which are ideal, both functionally and esthetically.

Lean Manufacturing Improves Emergency Department Throughput and Patient Satisfaction.

A multidisciplinary team led by nursing leadership and physicians developed a plan to meet increasing demand and improve the patient experience in the ED without expanding the department's current resources. The approach included Lean tools and engaged frontline staff and physicians. Applying Lean management principles resulted in quicker service, improved patient satisfaction, increased capacity, and reduced resource utilization. Incorporating continuous daily management is necessary for sustainment of continuous improvement activities.

Pilot trial of an electronic decision support to improve care for emergency department patients with acute heart failure.

AIMS: Emergency department (ED) providers play an important role in the management of patients with acute heart failure (AHF). We present findings from a pilot study of an electronic decision support that includes personalized risk estimates using the STRIDE-HF risk tool and tailored recommendations for initiating guideline directed medical therapy (GDMT) among appropriate patients. METHODS: Among ED patients treated for AHF who were discharged from the ED or the ED-based observation unit in two EDs from 1 January 2023 to 31 July 2023, we assess prescriptions to the four classes of GDMT at two intervals: (1) ED arrival and (2) ED discharge. Specifically, we report active prescriptions for beta-blockers (BBs), renin-angiotensin receptor system inhibitors (RASis), sodium-glucose transport protein 2 inhibitors (SGLT2is) and mineralocorticoid receptor antagonists (MRA) among patients with reduced ejection fraction (HFrEF) and mildly reduced (HFmrEF). Second, we describe rates of 30-day serious adverse events (SAE) (death, cardiopulmonary resuscitation, balloon-pump insertion, intubation, new dialysis, myocardial infarction or coronary revascularization) among patients predicted to be very low risk by STRIDE-HF and discharged home. RESULTS: Among 234 discharged patients, 55% were female and 76% were non-White. We found 51 (21.8%), 21 (9.0%) and 126 (53.8%) had HFrEF, HFmEF and HFpEF, respectively, while 36 (15.4%) were missing EF, and 51 (22%) were very low risk, 82 (35%) were low risk, 60 (26%) were medium risk and 41 (18%) were high risk. Among HFrEF patients, 68.6%, 66.7%, 25.5% and 19.6% were on a RASi, BB, SGLT2i and MRA, respectively, at ED arrival, while 42.9%, 66.7%, 14.3% and 4.8% of HFmrEF patients were on a RASi, BB, SGLT2i and MRA, respectively. Among patients with HFpEF, only 6 (4.8%) were on an SGLT2i at ED arrival. The most prescribed new medication at ED discharge was an SGLT2i, with a nearly 10% increase in the proportion of patients with an active prescription for SGLT2i at ED discharge among HFrEF and HFmEF patients. We observed no 30-day SAE among the 51 patients predicted to be very low risk and discharged home. CONCLUSIONS: Ongoing treatment with GDMT at ED arrival was sub-optimal. Initiation among appropriate patients at discharge may be feasible and safe.

Physicians' Perceptions of Clinical Decision Support to Treat Patients With Heart Failure in the ED.

Importance: Clinical decision support (CDS) could help emergency department (ED) physicians treat patients with heart failure (HF) by estimating risk, collating relevant history, and assisting with medication prescribing if physicians' perspectives inform its design and implementation. Objective: To evaluate CDS usability and workflow integration in the hands of ED physician end users who use it in clinical practice. Design, Setting, and Participants: This mixed-methods qualitative study administered semistructured interviews to ED physicians from 2 community EDs of Kaiser Permanente Northern California in 2023. The interview guide, based on the Usability Heuristics for User Interface Design and the Sociotechnical Environment models, yielded themes used to construct an electronic survey instrument sent to all ED physicians. Main Outcomes and Measures: Main outcomes were physicians' perceptions of using CDS to complement clinical decision-making, usability, and integration into ED clinical workflow. Results: Seven key informant physicians (5 [71.4%] female, median [IQR] 15.0 [9.5-15.0] years in practice) were interviewed and survey responses from 51 physicians (23 [45.1%] female, median [IQR] 14.0 [9.5-17.0] years in practice) were received from EDs piloting the CDS intervention. Response rate was 67.1% (51 of 76). Physicians suggested changes to CDS accessibility, functionality, and workflow integration. Most agreed that CDS would improve patient care and fewer than half of physicians expressed hesitation about their capacity to consistently comply with its recommendations, citing workload concerns. Physicians preferred a passive prompt that encouraged, but did not mandate, interaction with the CDS. Conclusions and Relevance: In this qualitative study of physicians who were using a novel CDS intervention to assist with ED management of patients with acute HF, several opportunities were identified to improve usability as well as several key barriers and facilitators to CDS implementation.

Pediatric erythromelalgia: a retrospective review of 32 cases evaluated at Mayo Clinic over a 37-year period.

BACKGROUND: Erythromelalgia has not been well characterized in the pediatric population. OBJECTIVE: We sought to review our experience of erythromelalgia in the pediatric age group. METHODS: We conducted a retrospective review of patients 18 years of age and younger with a diagnosis of erythromelalgia who were examined at Mayo Clinic in Rochester, MN, from 1970 to 2007. RESULTS: The records of 32 patients (girls, 22 [69%]) were evaluated. Mean age was 14.1 years (range, 5-18 years) and mean time to diagnosis was 5.2 years. Seven patients (22%) had a first-degree relative with erythromelalgia; 4 were from the same family. Physical activity was limited because of discomfort in 21 patients (66%) and school attendance was affected in 11 patients (34%). Noninvasive vascular studies, which compared temperature, laser Doppler flow, and transcutaneous oximetry in the toes, identified vascular abnormalities in 13 (93%) of 14 patients. Neurophysiologic studies with autonomic reflex screening (including quantitative sudomotor axon reflex test and thermoregulatory sweat testing) showed evidence of a small-fiber neuropathy involving the skin in 10 (59%) of 17 patients studied; there was no evidence of large-fiber neuropathy in 20 patients in whom electromyographic and nerve conduction studies were performed. Topical lidocaine was the most commonly prescribed treatment (44%). Fifteen patients were monitored for an average of 9.1 years (median, 5.0 years; range, 0.4-23.7 years). At last follow-up, 5 patients had stable disease, 4 showed improvement, two had resolution, one reported worsening of symptoms, and 3 had died (one suicide). LIMITATIONS: Conclusions are limited because this was a retrospective chart review. CONCLUSION: Erythromelalgia in pediatric patients is associated with substantial morbidity and even death. The majority of cases are not inherited. Most patients studied have associated small-fiber neuropathy. The disease course is variable. A reliable and safe treatment has not been determined.

Complications of cutaneous surgery in patients taking clopidogrel-containing anticoagulation.

BACKGROUND: Most anticoagulants are not associated with increased risk of severe complications during cutaneous surgery, but no data exist on clopidogrel. OBJECTIVE: We sought to determine frequency and severity of perioperative complications in patients taking clopidogrel-containing anticoagulation. METHODS: This was a retrospective review of medical records of patients undergoing Mohs micrographic surgery at Mayo Clinic, Rochester, MN, while taking clopidogrel-containing anticoagulation between 2004 and 2008, compared with control subjects taking aspirin monotherapy or no anticoagulants. RESULTS: In all, 220 patients taking clopidogrel-containing anticoagulation underwent 363 surgical procedures on 268 occasions. Severe complications occurred in 11 of 363 surgical sites in 10 cases. Clopidogrel-containing anticoagulation was 28 times more likely than no anticoagulation and 6 times more likely than aspirin monotherapy to result in severe complications after Mohs procedures (P < .001 and P = .022, respectively). Severe complications were 8 times more likely after Mohs procedures in patients taking both clopidogrel and aspirin than in control subjects taking aspirin monotherapy (P = .009). No statistically significant difference was found between patients taking clopidogrel monotherapy and control subjects not taking anticoagulants (P = .15). Patients experiencing severe complications were more likely to have larger postoperative surgical sites (P < .001). No thrombotic complications were encountered with discontinuation of clopidogrel-containing anticoagulation; a postoperative thrombotic complication occurred in one patient whose clopidogrel-containing anticoagulation regimen was modified. LIMITATIONS: Retrospective nature of study, possible recall bias as a result of telephone contact, and small number of severe complications were limitations, which reduced study power. CONCLUSION: Cutaneous surgery in patients taking clopidogrel-containing anticoagulation is associated with an increased risk of nonlife-threatening severe complications.

Superficial granulomatous pyoderma: a case in an 11-year-old girl and review of the literature.

Superficial granulomatous pyoderma is a rare entity thought to be a variant of pyoderma gangrenosum and is often mistaken for classic pyoderma gangrenosum. Superficial granulomatous pyoderma has mainly been described in adults. We describe a case of Superficial granulomatous pyoderma in an 11-year-old girl and present a review of the literature. Superficial granulomatous pyoderma maintains clinical and histopathologic characteristics distinct from classic pyoderma gangrenosum and has a more favorable prognosis. It is often responsive to conservative treatment.

Segmental cutaneous piloleiomyomata.

A 60-year-old white man seen in consultation for "chronic zoster" presented with a 30-year history of persistent, painful cutaneous lesions on his right flank. His pain was episodic and exacerbated by physical touch and emotional stress. He denied lesion sensitivity to cold or heat. Application ofcapsaicin cream had been without benefit. There was no family history of similar lesions. Physical examination revealed multiple, pink to violaceous, firm, tender nodules (3-7 mm) arising on the right flank in a segmental distribution (Figure 1). No other lesions were noted. A biopsy specimen showed findings of dermal proliferation of spindle-shaped cells with eosinophilic cytoplasm and blunt-ended nuclei without cytologic atypia (Figure 2A and Figure 2B). All of these findings were compatible with a diagnosis of segmental cutaneous piloleiomyomata. He declined surgical or medical intervention.

Death following coral snake bite in the United States--first documented case (with ELISA confirmation of envenomation) in over 40 years.

We report the first documented death due to a coral snake (Micrurus species) in the United States (U.S.) in over 40 years. The victim failed to seek medical care following the bite of an eastern coral snake (Micrurus fulvius) and succumbed within hours. Post-mortem proof of envenomation was obtained using an ELISA (enzyme-linked immunosorbent assay) developed specifically for this investigation. U.S. coral snakes are briefly reviewed in terms of their venom compositions, their clinical effects, and proper pre-hospital and hospital management. The clinical significance of the impending absence of commercially available antivenom for coral snake bites in the U.S. is highlighted.

The Ebbinghaus retention curve: training does not increase the ability to apply pressure immobilisation in simulated snake bite--implications for snake bite first aid in the developing world.

Pressure immobilisation (PIM) has been recommended for field management of bites by some venomous snakes. A narrow range of pressures under the encompassing wrap is necessary for PIM to limit venom spread. This study sought to evaluate the effect of focused training on volunteers' ability to apply PIM and to retain such skill over time. Forty volunteers were randomly divided into two groups: Group 1 (N=20; controls) received standard written instructions in PIM application; and Group 2 (N=20) received focused instruction during a 4-h training session (including hands-on practice and real-time feedback regarding pressures achieved). After voicing confidence with the technique, volunteers were tested at 1h, 1 day, 3 days and 3 months post training. One-hour post training, no volunteers in the control group were successful in applying PIM with the correct pressure. Twelve volunteers (60%) in Group 2 achieved target pressures 1h after training. However, there was rapid loss of ability to apply PIM correctly by Group 2, falling to just 25% success at 3 days, with little further deterioration at 3 months. Neither written instructions nor intense training with feedback adequately prepares individuals to apply PIM with correct pressures under the wrap.

Meyerson's naevus: a clinical and histopathological study of 11 cases.

We undertook a clinical and histopathological analysis of patients presenting with Meyerson's naevi. Eleven patients with the characteristic histological features of a Meyerson's naevus were identified over a 5-year period. Diagnostic criteria included epidermal spongiosis and a dermal inflammatory infiltrate associated with a banal junctional or compound naevus. Cases were excluded if naevus cells showed moderate to severe atypia or regression. Patients were contacted by phone and interviewed regarding their lesions. The most common clinical appearance was a solitary, pruritic, erythematous eruption encircling a pre-existing pigmented naevus. The trunk and proximal upper extremities were preferentially affected. Only one clinician listed Meyerson's naevus in the clinical differential diagnosis. All cases demonstrated a pigmented junctional or compound naevus with epidermal spongiosis, parakeratosis and a perivascular lymphohistiocytic inflammatory infiltrate with scattered eosinophils. The inflammatory infiltrate consisted almost exclusively of CD3+ lymphocytes, the majority of which were CD4+. However, a substantial number were CD8+. In all patients, the lesions cleared with excision or spontaneously, without recurrence or progression to melanoma. The aetiology of this entity remains unclear and most clinicians are unlikely to be familiar with it.

Effects of implementing a rapid admission policy in the ED.

OBJECTIVE: The purpose of this study is to determine the impact of a new rapid admission policy (RAP) on emergency department (ED) length of stay (EDLOS) and time spent on ambulance diversion (AD). METHODS: The RAP, instituted in January 2005, allows attending emergency physicians to send stable patients, requiring admission to the general medicine service, directly to available inpatient beds. The RAP thereby eliminates 2 conventional preadmission practices: having admitting physicians evaluate the patient in the ED and requiring all diagnostic testing to be complete before admission. We compared patient characteristics, percentage of patients leaving without being seen, EDLOS for admitted patients, time on AD, and total adjusted facility charge for a 3-month period after the RAP implementation to the same period of the prior year. RESULTS: There was a 1.1% increase in census with no difference in patient demographics, acuity, or disposition categories for the 2 periods. The EDLOS decreased on average by 10.1 minutes (95% confidence interval [CI], 3.3-17.0 minutes), resulting in an average of 4.2 hours of extra bed availability per day. Weekly minutes of AD decreased 169 minutes (95% CI, 29-310 minutes). There was also a 3.2% increase (95% CI, 3.1%-3.3%) in adjusted facility charge between these periods in 2005 compared with 2004. CONCLUSIONS: The RAP resulted in a small decrease in the EDLOS, which likely decreased AD time. The resulting small increase in ED volume and higher acuity ambulance patients significantly improved ED revenue. Wider implementation of the policy and more uniform use among emergency physicians may further improve these measures.

Resection of a large atrial hemangioma using a bloodless surgical technique: a case report.

We present a biatrial hemangioma in a Jehovah's Witness patient. Hemangioma is extremely rare, accounting for 1% to 2% of benign cardiac tumors. Complete resection of a large hemangioma is mandatory due to its potentially life-threatening risk. In Jehovah's Witness patients, it is necessary to employ bloodless surgery protocols to maximize the patient's outcome. Our patient had undergone 6 weeks of monitoring and erythropoietin therapy prior to surgery, raising her hemoglobin level from 11.6 g/dL to 16.8 g/dL. Intraoperative bloodless surgical protocols as well as a continuous blood circuit were utilized. The patient's hemoglobin level on postoperative day one was 14.5 g/dL; one year postsurgery, the patient was symptom free.
