Women's interest, knowledge, and attitudes relating to anti-Mullerian hormone testing: a randomized controlled trial.

STUDY QUESTION: What is the impact of co-designed, evidence-based information regarding the anti-Mullerian hormone (AMH) test on women's interest in having the test? SUMMARY ANSWER: Women who viewed the evidence-based information about the AMH test had lower interest in having an AMH test than women who viewed information produced by an online company selling the test direct-to-consumers. WHAT IS KNOWN ALREADY: Online information about AMH testing often has unfounded claims about its ability to predict fertility and conception, and evidence suggests that women seek out and are recommended the AMH test as a measure of their fertility potential. STUDY DESIGN, SIZE, DURATION: An online randomized trial was conducted from November to December 2022. Women were randomized (double-blind, equal allocation) to view one of two types of information: co-designed, evidence-based information about the AMH test (intervention), or existing information about the AMH test from a website which markets the test direct-to-consumers (control). A total of 967 women were included in the final analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were women recruited through an online panel, who were aged 25-40 years, living in Australia or The Netherlands, had never given birth, were not currently pregnant but would like to have a child now or in the future, and had never had an AMH test. The primary outcome was interest in having an AMH test (seven-point scale; 1 = definitely NOT interested to 7 = definitely interested). Secondary outcomes included attitudes, knowledge, and psychosocial and behavioural outcomes relating to AMH testing. MAIN RESULTS AND THE ROLE OF CHANCE: Women who viewed the evidence-based information about the AMH test had lower interest in having an AMH test (MD = 1.05, 95% CI = 0.83-1.30), less positive attitudes towards (MD = 1.29, 95% CI = 4.57-5.70), and higher knowledge about the test than women who viewed the control information (MD = 0.75, 95% CI = 0.71-0.82). LIMITATIONS, REASONS FOR CAUTION: The sample was more highly educated than the broader Australian and Dutch populations and some measures (e.g. influence on family planning) were hypothetical in nature. WIDER IMPLICATIONS OF THE FINDINGS: Women have higher knowledge of and lower interest in having the AMH test when given evidence-based information about the test and its limitations. Despite previous studies suggesting women are enthusiastic about AMH testing to learn about their fertility potential, we demonstrate that this enthusiasm does not hold when they are informed about the test's limitations.

Application of acid and heavy metal resistant bacteria from rat-hole coal mines in bioremediation strategy.

The Gram-negative bacteria isolated from acid mine drainage (AMD) of rat-hole coal mines were found to be resistant to acidic conditions as well as Fe, Cd, and Cr. The minimum inhibitory concentration (MIC) and maximum bactericidal concentration (MBC) of iron, cadmium, and chromium against the isolates of Enterobacter huaxiensis KHED8 were 4000, 4096, and 256 mg/L, respectively, while the MIC and MBC of Fe, Cd, and Cr against two isolates (KH5M10 and KHCL12) of Serratia marcescens subsp. sakuensis isolates were 4000, 8192, and 256 mg/L, respectively. It was also found that E. huaxiensis KHED8 was able to remove 89%, 90%, and 82.45% of Fe, Cd, and Cr, respectively, and the two isolates of S. marcescens subsp. sakuensis KH5M10 and KHCL12 were able to remove 90%, 95%, and 85.62% of Fe, Cd, and Cr, respectively. The findings of the study provide lead to the use of these heavy metals resistant bacterial isolates for bioremediation of heavy metals laden AMD prevalent in unique rat-hole coal mines.

Vitamin E administration does not ameliorate tramadol-associated impairment of testicular function in Wistar rats.

Tramadol is widely abused in Nigeria and has been reported to cause fertility decline via testicular oxidative stress. This study investigated the effect of vitamin E, an antioxidant on some reproductive parameters in male Wistar rats administered tramadol. Twenty male Wistar rats (180-200 g) were randomly assigned into four groups (n = 5) thus: Control (0.2 ml vehicle: olive oil), tramadol-treated (20 mg/kg of tramadol), vitamin E-treated (100 mg/kg of vitamin E) and tramadol + vitamin E-treated (received tramadol and vitamin E) groups. Drugs were administered orally and daily for 28 days. Sperm count, Johnsen's score, germinal epithelial height and serum testosterone, follicle-stimulating hormone (FSH) and luteinising hormone (LH) concentrations were significantly (p < .05) decreased in tramadol-treated and tramadol + vitamin E compared with control and vitamin E-treated groups. Sperm motility, morphology, viability, seminiferous tubular diameter, Leydig cell count, Sertoli cell count and malondialdehyde, superoxide dismutase, glutathione peroxidase and catalase concentrations were not significantly different among the groups. Histology of testis and epididymis in all groups showed no toxicity but decreased sperm population in tramadol-treated and tramadol + vitamin E-treated groups. Tramadol did not cause testicular oxidative stress but impaired testicular function by suppressing testosterone, FSH and LH secretion. Vitamin E administration could not attenuate this impairment in testicular function.

Introduction of the American Academy of Facial Plastic and Reconstructive Surgery FACE TO FACE Database.

The American Academy of Facial Plastic and Reconstructive Surgery FACE TO FACE database was created to gather and organize patient data primarily from international humanitarian surgical mission trips, as well as local humanitarian initiatives. Similar to cloud-based Electronic Medical Records, this web-based user-generated database allows for more accurate tracking of provider and patient information and outcomes, regardless of site, and is useful when coordinating follow-up care for patients. The database is particularly useful on international mission trips as there are often different surgeons who may provide care to patients on subsequent missions, and patients who may visit more than 1 mission site. Ultimately, by pooling data across multiples sites and over time, the database has the potential to be a useful resource for population-based studies and outcome data analysis. The objective of this paper is to delineate the process involved in creating the AAFPRS FACE TO FACE database, to assess its functional utility, to draw comparisons to electronic medical records systems that are now widely implemented, and to explain the specific benefits and disadvantages of the use of the database as it was implemented on recent international surgical mission trips.

Testicular and Epididymal Histology of Rats Chronically Administered High Doses of Phosphodiesterase-5 Inhibitors and Tramadol.

Testicular oxidative stress, endocrine disruption and abnormal spermatogenesis in rats exposed to high doses ofphosphodiesterase-5 inhibitors (PDE5i) and opioids, with poor reversibility following withdrawal of treatment had beenreported. In this study, we examined the histopathological effects of high doses of sildenafil, tadalafil, tramadol andsildenafil+tramadol on the testes and epididymis of rats. Seventy male rats (180 - 200 g b.w) were assigned to one of fivegroups (n = 14), namely; A: control (0.2 mL normal saline), B: sildenafil (1 mg/100g b.w), C: tadalafil (1 mg/100g b.w), D:tramadol (2 mg/100g b.w) and E: sildenafil+tramadol group (dose as in groups B and D). The drugs were administered orallyfor 8 weeks. Seven rats were sacrificed per group while the remaining 7/group continued for 8 weeks without treatment.Histopathological examination was carried out at the end of both phases. After 8 weeks of treatment, mean Johnsen'stesticular biopsy score (MJTBS) and Leydig cell count decreased significantly (p=0.001) in all treated groups compared withthe control. The MJTBS and Leydig cell count decreased significantly in tramadol (p = 0.05) and sildenafil+tramadol (p<0.01)groups compared with tadalafil group. After recovery, MJTBS and Leydig cell count were significantly (p<0.05) lower in all the groups compared with the control. Histology of the testes of rats in groups B - E showed reduced germ cell andspermatozoa population in the seminiferous tubules after 8 weeks treatment. Additionally, their epididymis showed decreasedspermatozoa density. There was no complete reversibility of histopathological alterations following withdrawal of treatment.High doses of sildenafil, tadalafil, tramadol or sildenafil+tramadol impact negatively on testicular histology with poorreversal following withdrawal of treatment.

Re-treatment of chronic idiopathic thrombocytopenic purpura with rituximab: literature review.

The aim of this literature review was to identify from published reports, the characteristics and response to rituximab of nine patients with chronic idiopathic thrombocytopenic purpura who had been re-treated after responding to an initial course of therapy. The female/male ratio of re-treated patients was eight, suggesting selection or their suitability for treatment because the female/male ratio of 95 initially treated patients in all published reports between December 1998 and June 2003 was 2. Almost three times as many females responded to the first course of rituximab. All second responses, where recorded, were complete despite two previous partial responses and one minor response. The duration of the second response was at least as durable and more so than the first. Of the nine re-treated patients, the two failures had not undergone splenectomy, yet had achieved a complete response to the first course. All four patients who had previously responded to intravenous immunoglobulin responded to both the initial and subsequent course of rituximab. The influence of prior splenectomy, response to intravenous immunoglobulin, and distinctive patterns of time course until platelet response suggest that there might be different mechanisms of response to rituximab.

Hyperactive ERK and persistent mTOR signaling characterize vemurafenib resistance in papillary thyroid cancer cells.

Clinical studies evaluating targeted BRAFV600E inhibitors in advanced thyroid cancer patients are currently underway. Vemurafenib (BRAFV600E inhibitor) monotherapy has shown promising results thus far, although development of resistance is a clinical challenge. The objective of this study was to characterize development of resistance to BRAFV600E inhibition and to identify targets for effective combination therapy. We created a line of BCPAP papillary thyroid cancer cells resistant to vemurafenib by treating with increasing concentrations of the drug. The resistant BCPAP line was characterized and compared to its sensitive counterpart with respect to signaling molecules thought to be directly related to resistance. Expression and phosphorylation of several critical proteins were analyzed by Western blotting and dimerization was evaluated by immunoprecipitation. Resistance to vemurafenib in BCPAP appeared to be mediated by constitutive overexpression of phospho-ERK and by resistance to inhibition of both phospho-mTOR and phospho-S6 ribosomal protein after vemurafenib treatment. Expression of potential alternative signaling molecule, CRAF, was not increased in the resistant line, although formation of CRAF dimers appeared increased. Expression of membrane receptors HER2 and HER3 was greatly amplified in the resistant cancer cells. Papillary thyroid cancer cells were capable of overcoming targeted BRAFV600E inhibition by rewiring of cell signal pathways in response to prolonged vemurafenib therapy. Our study suggests that in vitro culture of cancer cells may be useful in assessing molecular resistance pathways. Potential therapies in advanced thyroid cancer patients may combine vemurafenib with inhibitors of CRAF, HER2/HER3, ERK, and/or mTOR to delay or abort development of resistance.

BRCA1 regulation of epidermal growth factor receptor (EGFR) expression in human breast cancer cells involves microRNA-146a and is critical for its tumor suppressor function.

Breast cancer 1 (BRCA1)-associated breast cancers are mostly basal-like high-grade ductal carcinomas that frequently overexpress epidermal growth factor receptor (EGFR). Aberrant EGFR expression is correlated with disease progression, resistance to radiation and chemotherapy, and poor clinical prognosis. Although BRCA1 is involved in multiple cellular processes, its functional role in EGFR regulation remains enigmatic. Here, we report a previously unrecognized posttranscriptional mechanism by which BRCA1 regulates EGFR expression through the induction of miR-146a. We demonstrate that EGFR expression correlates negatively with BRCA1, whereas miR-146a levels increase with BRCA1. We show that BRCA1 binds to MIR146A promoter and activates transcription, which in turn attenuates EGFR expression. Knockdown of miR-146a in BRCA1-overexpressing cells negated this effect and suppressed its ability to inhibit proliferation and transformation. In archived triple-negative breast cancer samples, we show a strong positive correlation between BRCA1 and miR-146a expression. We also show that low expression of miR-146a strongly predicts positive lymph node status and is associated with distinctively poor overall survival of patients. Together, these observations provide an insight into a novel BRCA1miR-146aEGFR paradigm by which BRCA1 carries out an aspect of tumor suppressor function that is potentially amenable to therapeutic intervention.

mTOR inhibitors sensitize thyroid cancer cells to cytotoxic effect of vemurafenib.

Treatment options for advanced metastatic thyroid cancer patients are limited. Vemurafenib, a BRAFV600E inhibitor, has shown promise in clinical trials although cellular resistance occurs. Combination therapy that includes BRAFV600E inhibition and avoids resistance is a clinical need. We used an in vitro model to examine combination treatment with vemurafenib and mammalian target of rapamycin (mTOR) inhibitors, metformin and rapamycin. Cellular viability and apoptosis were analyzed in thyroid cell lines by trypan blue exclusion and TUNEL assays. Combination of vemurafenib and metformin decreased cell viability and increased apoptosis in both BCPAP papillary thyroid cancer cells and 8505c anaplastic thyroid cancer cells. This combination was also found to be active in vemurafenib-resistant BCPAP cells. Changes in expression of signaling molecules such as decreased mTOR expression in BCPAP and enhanced inhibition of phospho-MAPK in resistant BCPAP and 8505c were observed. The second combination of vemurafenib and rapamycin amplified cell death in BCPAP cells. We conclude that combination of BRAFV600E and mTOR inhibition forms the basis of a treatment regimen that should be further investigated in in vivo model systems. Metformin or rapamycin adjuvant treatment may provide clinical benefits with minimal side effects to BRAFV600E-positive advanced thyroid cancer patients treated with vemurafenib.

Zones of approach for craniofacial resection: minimizing facial incisions for resection of anterior cranial base and paranasal sinus tumors.

OBJECTIVE: Anterior cranial base tumors are surgically resected with combined craniofacial approaches that frequently involve disfiguring facial incisions and facial osteotomies. The authors outline three operative zones of the anterior cranial base and paranasal sinuses in which tumors can be resected with three standard surgical approaches that minimize transfacial incisions and extensive facial osteotomies. METHODS: The zones were defined by performing dissections on 10 cadaveric heads and by evaluating radiographic images of patients with anterior cranial base tumors. The three approaches performed on each cadaver were transbasal, transmaxillary, and extended transsphenoidal. RESULTS: Three zones of approach were defined for accessing tumors of the anterior cranial base, nasal cavity, and paranasal sinuses. Zone 1 is exposed by the transbasal approach, which is limited anteriorly by the supraorbital rim, posteriorly by the optic chiasm and clivus, inferiorly by the palate, and laterally by the medial orbital walls. This approach allows access to the entire anterior cranial base, nasal cavity, and the majority of maxillary sinuses. The limitation imposed by the orbits results in a blind spot in the superolateral extent of the maxillary sinus. Zone 2 is exposed by a sublabial maxillotomy approach and accesses the entire maxillary sinus, including the superolateral blind spot and the ipsilateral anterior cavernous sinus. However, access to the anterior cranial base is limited. Zone 3 is exposed by the transsphenoidal approach. This approach accesses the midline structures but is limited by the lateral nasal walls and intracavernous carotid arteries. An extended transsphenoidal approach allows further exposure to the anterior cranial base, clivus, or cavernous sinuses. The use of the endoscope facilitates tumor resection in the nasal cavity and paranasal sinuses. CONCLUSION: The operative zones outlined offer minimally invasive craniofacial approaches to accessing lesions of the anterior cranial base and paranasal sinuses, obviating facial incisions and facial osteotomies. Case illustrations demonstrating the approach selection paradigm are presented.

Neurosurgical implications of allergic fungal sinusitis.

OBJECT: Allergic fungal sinusitis (AFS) is a form of paranasal mycosis that often involves bone destruction and extension into the orbit and anterior skull base. Treatment consists of surgical extirpation and a course of corticosteroids. Despite frequent intracranial involvement, AFS is rarely reported in the neurosurgical literature. METHODS: The records of 21 patients with the histological diagnosis of AFS were reviewed. The histological diagnosis was based on findings of branching septated fungi interspersed with eosinophilic mucin and Charcot-Leyden crystals without fungal invasion of soft tissue. The average age of the 21 patients in this study was 25 years (range 9-46) and the male/female ratio was 3.75:1. All patients were immunocompetent. All had a history of chronic sinusitis and imaging findings of expansile disease involving multiple sinuses. Fifteen patients had nasal polyposis, eight had erosion of bone, which was observed on computerized tomography (CT) scans, eight had disease extending intracranially, and six had disease that involved the lamina papyracea. All patients underwent transnasal and/or transmaxillary endoscopic approaches for debridement and irrigation, six underwent orbital decompression, and three underwent a bifrontal craniotomy for removal of intracranial extradural disease. No patient had a cerebrospinal fluid leak. Postoperatively, one patient was treated with amphotericin B and the other 20 were treated with a short course of corticosteroids. The follow-up period ranged from 2 to 19 years. CONCLUSIONS: Allergic fungal sinusitis is a unique form of fungal disease that may mimic anterior skull base and paranasal sinus tumors. A cranial base team approach of neurosurgeons and otolaryngologists is recommended. Most cases can be successfully managed with transnasal and/or transmaxillary endoscopic techniques. A craniotomy is rarely indicated unless there is the suspicion of dural invasion or extensive intracranial and/or intraorbital involvement that is inaccessible from below.

Middle latency response in children with learning disabilities: preliminary findings.

The objective of this investigation was to determine if auditory middle latency responses (MLR) obtained from children with learning disabilities (LD) differ from those obtained from children without LD. Simultaneous recordings of auditory brainstem and middle latency responses were obtained in both vertex-ipsilateral (V-I) and vertex-contralateral derivations (V-C) in 22 children (11 LD and 11 normal) in the age range of eight to twelve years whose peripheral hearing was within normal limits to bilateral. The results indicate that for specific recording conditions, the latencies of middle latency responses differ significantly between children with LD and a normal group of children.

Bcl-2/caspase 3 mucosal imbalance favors T cell resistance to apoptosis in dogs with inflammatory bowel disease.

Canine idiopathic inflammatory bowel disease (IBD) is believed to result from complex interplay between genetic, microbial, and immunologic factors. Abnormal cell death by apoptosis may result in the persistence of activated intestinal T cells that contribute to mucosal inflammation and clinical severity. To test this hypothesis, we investigated the mucosal expression of pro- and anti-apoptotic proteins in different intestinal compartments and their association with inflammatory indices in dogs with IBD. Apoptosis of lamina propria (LP) T cells in duodenal, ileal, and colonic tissues in control and IBD dogs was analyzed by caspase 3/Bcl-2 immunohistochemistry and TUNEL assays. Densities and distributions of LP caspase 3 and Bcl-2 cells were correlated to histopathologic lesions and the clinical activity index (CIBDAI). Compared to control tissues, IBD dogs had significantly (P<0.01) fewer caspase 3 cells in colonic mucosa. Double immunostaining identified the majority of apoptotic cells as TUNEL(+)/caspase 3(+). Within intestinal mucosa of IBD dogs, there were significantly greater numbers of Bcl-2 cells at the apical and basilar villus in the duodenum as compared to the colon and to the apical and basilar villus in the ileum (P<0.001 for all comparisons). There were significantly greater numbers of Bcl-2 cells at the apical and basilar villus of the duodenum but significantly fewer numbers of Bcl-2 cells at the apical villus of the ileum in IBD dogs compared with controls (P<0.001, P<0.001, and P<0.02, respectively). There was a significant association between the number of Bcl-2 cells in the duodenum of IBD dogs and the CIBDAI (P<0.001 each for mild, moderate and severe clinical IBD). In conclusion, apoptosis of T lymphocytes varies within intestinal compartments of dogs with IBD. Mucosal imbalance of Bcl-2/caspase 3 expression favors T cell resistance to apoptosis which may contribute to T cell accumulation and chronic intestinal inflammation, similar to human IBD.

MRI findings of causalgia of the lower extremity following transsphenoidal resection of pituitary tumor.

Background. Causalgia is continuing pain, allodynia, or hyperalgesia after nerve injury with edema, changes in skin blood flow, or abnormal sudomotor activity. Here we report a case of lower extremity causalgia following elective transsphenoidal resection of a pituitary tumor in a young man. Clinical Presentation. A 33-year-old man with acromegaly underwent elective sublabial transsphenoidal resection of his pituitary tumor. During the three-hour surgery, the lower limbs were kept in a supine, neutral position with a pillow under the knees. The right thigh was slightly internally rotated with a tape to expose fascia lata, which was harvested to repair the sella. Postoperatively, he developed causalgia in a distal sciatic and common peroneal nerve distribution. Pain was refractory to several interventions. Finally, phenoxybenzamine improved his pain significantly. Conclusions. Malpositioning in the operating room resulted in causalgia in this young man. Phenoxybenzamine improved, and ultimately resolved, his symptoms. Improvement in his pain symptoms correlated with resolution of imaging changes in the distal sciatic and peroneal nerves on the side of injury.

Estrogen activity as a preventive and therapeutic target in thyroid cancer.

Thyroid cancer is the most common endocrine-related cancer with increasing incidences during the last five years. Interestingly, according to the American Thyroid Association, the incidences of thyroid proliferative diseases occur four to five times more in women than in men with the risk of developing thyroid disorders being one in every eight females. Several epidemiological studies have suggested a possible correlation between incidences of thyroid malignancies and hormones but the precise contribution of estrogen in thyroid proliferative disease initiation, and progression is not well understood. This review is an attempt to define the phenotypic and genotypic modulatory effects of estrogen on thyroid proliferative diseases. The significance and relevance of expression of estrogen receptors, α and ß, in normal and malignant thyroid tissues and their effects on different molecular pathways involved in growth and function of the thyroid gland are discussed. These novel findings open up areas of developing alternative therapeutic treatments and preventive approaches which employ the use of antiestrogen to treat thyroid malignancies.

Inhibition of uPAR and uPA reduces invasion in papillary thyroid carcinoma cells.

OBJECTIVES/HYPOTHESIS: We analyzed the expression of urokinase plasminogen activator (uPA) and its receptor (uPAR) in papillary thyroid carcinoma (PTC) and normal thyroid tissue and examined in vitro how uPA and uPAR contribute to an invasive/metastatic phenotype, and the functional consequences of inhibiting this system. STUDY DESIGN: Retrospective chart review of PTC patients, followed by prospective study using previously obtained patient tissue and PTC cellular models. METHODS: uPA and uPAR RNA and protein levels were analyzed in PTC patient tissue samples, PTC and normal thyroid tissue culture cells, and conditioned media (CM) using quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and/or Western blotting. The plasminogen-activating ability of CM was examined using dark-quenched casein fluorimetry and casein-plasminogen gel zymography. The invasive potentials of the PTC and normal thyroid epithelial cell lines were assessed using an in vitro cellular invasion/migration system. RESULTS: uPA and uPAR RNA and protein levels were increased in PTC patient samples and PTC cells relative to controls. uPA and uPAR RNA were also significantly higher in patients with metastatic disease. Casein-plasminogen zymography and Western blotting demonstrated increased active uPA secreted by PTC cells compared with normal thyroid cells. Fluorimetric assays revealed that the PTC cells' CM was able to activate plasminogen, resulting in measurable casein hydrolysis. This casein hydrolysis was prevented by the addition of several specific uPA inhibitors. Finally, the in vitro invasion phenotypes of PTC cells were augmented by the addition of plasminogen, and this augmentation was reversed by inhibitory anti-uPA and anti-uPAR antibodies. CONCLUSIONS: These data provide new functional evidence of the uPA/uPAR system's role in PTC invasion/metastasis and demonstrate the attractiveness of uPA and uPAR as molecular biomarkers and therapeutic targets.

Comparison of three common tonsillectomy techniques: a prospective randomized, double-blinded clinical study.

OBJECTIVE: To evaluate three current tonsillectomy techniques--intracapsular microdebridement, intracapsular coblation, and traditional extracapsular electrocautery dissection--comparing surgical parameters, efficacy, and morbidity in the treatment for obstructive sleep disordered breathing in children. STUDY DESIGN: Prospective, double-blinded study with follow-up by telephone interview. METHOD: From February 2004 to July 2006, a total of 156 patients between the ages of 6 months and 22 years scheduled for adenotonsillectomy were randomly assigned to electrocautery, coblator, and microdebrider groups. OUTCOME MEASURES: 1) Patient demographics; 2) Intraoperative time; 3) Surgeon's perception of difficulty; 4) Indicators of postoperative morbidity: pain, use of pain medication, return to diet, and activity level; 5) Complications; 6) Cost. RESULTS: Microdebrider technique produced the shortest total surgical time, averaging 16 minutes. Use of coblation resulted in 2 less days of pain medication compared to electrocautery. Patients in the coblator and microdebrider groups returned to a normal diet 1.51 days and 1.77 days earlier, respectively, than in the electrocautery group. They also returned to preoperative activity levels 1.85 days and 2.06 days earlier than in the electrocautery group. Of all three methods, the microdebrider was the most cost effective. The coblator and microdebrider did not differ significantly from each other in all other parameters. The three techniques showed no statistically significant difference in assessment of difficulty, average pain scores, or postoperative complications. CONCLUSIONS: Postoperative recovery following intracapsular adenotonsillectomy in children with obstructive sleep apnea is significantly earlier with use of either the coblator or microdebrider versus traditional extracapsular tonsillectomy with electrocautery. Microdebrider and coblator were comparable in all other areas except for shorter operative time and less cost for the microdebrider.

Access to state-of-the-art healthcare: a missing dynamic in consumer selection of a retirement community.

The top ten retirement destinations in the United States are compared to the State of Michigan with regard to the quality of medical care that can be readily obtained in the event of a medical emergency. Access to care during the following three medical emergencies was analyzed: cardiac arrest, thromboembolic (ischemic) stroke, and severe traumatic injury. In all instances, successful treatment is dependent on timely access to care. The authors report that, when combined with the health status of baby boomers and their migratory trends on retirement, access to tertiary medical care for the treatment of cardiac arrest, certified primary stroke centers, and level I trauma centers is the missing dynamic in the choice of retirement community among today's prospective retirees. They recommend that physicians encourage this patient population to consider such factors when choosing a retirement community.
