1.Spontaneous elbow hemarthrosis identified by point-of-care ultrasound.
David C MACKENZIE ; Scott MCCORVEY
Clinical and Experimental Emergency Medicine 2017;4(1):60-63
Traumatic or spontaneous hemarthroses are an important cause of joint effusions, and can complicate innate or acquired coagulopathies. The elbow is an unusual location for a spontaneous hemarthrosis; we describe a previously unreported case of warfarin-induced spontaneous elbow hemarthrosis, diagnosed by point-of-care ultrasound. On the basis of clinical and ultrasound findings arthrocentesis was deferred, and the patient was successfully treated with warfarin reversal and conservative care. Physical examination is unreliable for the detection of a joint effusion, and misdiagnosis and can lead to unnecessary investigation or resource use. Point-of-care ultrasound allows accurate, prompt, direct visualization of a joint effusion, and non-invasive confirmation of a hemarthrosis. Ultrasound can facilitate accurate diagnosis and characterization of joint effusions to improve the care of patients with coagulopathy.

Malignant transformation of urachal adenoma is exceedingly rare, with intestinal metaplasia as the most common contributing mechanism. It is recommended that a urachal adenoma be regarded as a pre-malignant condition and be subject to endoscopic surveillance. A local en block excision of the tumor mass with urachalectomy and umbilectomy results in possible long-term survival. The median survival after platinum-based chemotherapy is limited for patients with extravesical disease. Here we report a case of synchronous urothelial carcinoma of the bladder and urachal adenoma that transformed into adenocarcinoma.

Journal of Gynecologic Oncology 2008;19(4):218-222
The Gynecologic Oncology Group (GOG) has conducted multiple trials related to malignancies of the uterine corpus. Recently, several of these trials have been presented and/or published. Areas of focus included the feasibility of laparoscopic staging for endometrial cancer, the adjuvant management of locally advanced endometrial cancer, whole abdominal irradiation in maximally resected advanced endometrial carcinoma, and combination chemotherapy regimens for stage I and II carcinosarcoma after primary surgery and for advanced or recurrent carcinosarcoma. This article will discuss the background and details of each of these important advances.

A static, unilateral, and focal bone depression located lingually within the ascending ramus, identical to the Stafne's bone cavity of the angle of the mandible, is being reported. During development of the mandible, submandibular gland inclusion may lead to the formation of a lingual concavity, which could contain fatty tissue, blood vessels, or soft tissue. However, similar occurrences in the ascending ramus at the level of the parotid gland are extremely rare. Similar cases were previously reported in dry, excavated mandibles, and 3 cases were reported in living patients. A 52-year-old African American male patient was seen for pain in the mandibular teeth. Panoramic radiography showed an unusual concavity within the left ascending ramus. Cone-beam computed tomography confirmed this incidental finding. The patient was cleared for the extraction of non-restorable teeth and scheduled for annual follow-up.

Journal of Cerebrovascular and Endovascular Neurosurgery 2021;23(1):6-15
Objective:
Moyamoya disease (MMD) is a vasculopathy of the internal carotid arteries with ischemic and hemorrhagic sequelae. Surgical revascularization confers upfront peri-procedural risk and costs in exchange for long-term protective benefit against hemorrhagic disease. The authors present a cost-effectiveness analysis (CEA) of surgical versus non-surgical management of MMD.
Methods:
A Markov Model was used to simulate a 41-year-old suffering a transient ischemic attack (TIA) secondary to MMD and now faced with operative versus nonoperative treatment options. Health utilities, costs, and outcome probabilities were obtained from the CEA registry and the published literature. The primary outcome was incremental cost-effectiveness ratio which compared the quality adjusted life years (QALYs) and costs of surgical and nonsurgical treatments. Base-case, one-way sensitivity, two-way sensitivity, and probabilistic sensitivity analyses were performed with a willingness to pay threshold of $50,000.
Results:
The base case model yielded 3.81 QALYs with a cost of $99,500 for surgery, and 3.76 QALYs with a cost of $106,500 for nonsurgical management. One-way sensitivity analysis demonstrated the greatest sensitivity in assumptions to cost of surgery and cost of admission for hemorrhagic stroke, and probabilities of stroke with no surgery, stroke after surgery, poor surgical outcome, and death after surgery. Probabilistic sensitivity analyses demonstrated that surgical revascularization was the cost-effective strategy in over 87.4% of simulations.
Conclusions
Considering both direct and indirect costs and the postoperative QALY, surgery is considerably more cost-effective than non-surgical management for adults with MMD.

Journal of Cerebrovascular and Endovascular Neurosurgery 2020;22(1):1-7
Objective:
Although stroke guidelines recommend antiplatelets be started 24 hoursafter tissue plasminogen activator (tPA), select mechanical thrombectomy (MT)patients with luminal irregularities or underlying intracranial atherosclerotic diseasemay benefit from earlier antiplatelet administration.
Methods:
We explore the safety of early (< 24 hours) post-tPA antiplatelet use byretrospectively reviewing patients who underwent MT and stent placement for acuteischemic stroke from June 2015 to April 2018 at our institution.
Results:
Six patients met inclusion criteria. Median presenting and pre-operativeNational Institutes of Health Stroke Scale scores were 14 (Interquartile Range [IQR]5.5-17.3) and 16 (IQR 13.7-18.7), respectively. Five patients received standard intravenous(IV) tPA and one patient received intra-arterial tPA. Median time from symptomonset to IV tPA was 120 min (IQR 78-204 min). Median time between tPA and antiplateletadministration was 4.9 hours (IQR 3.0-6.7 hours). Clots were successfullyremoved from the internal carotid artery (ICA) or middle cerebral artery (MCA) in 5patients, the anterior cerebral artery (ACA) in one patient, and the vertebrobasilarjunction in one patient. All patients underwent MT before stenting and achievedthrombolysis in cerebral infarction 2B recanalization. Stents were placed in the ICA(n=4), common carotid artery (n=1), and basilar artery (n=1). The median time fromstroke onset to endovascular access was 185 min (IQR 136-417 min). No patientsexperienced symptomatic post-procedure intracranial hemorrhage (ICH). Medianmodified Rankin Scale score on discharge was 3.5.
Conclusions
Antiplatelets within 24 hours of tPA did not result in symptomatic ICHin this series. The safety and efficacy of early antiplatelet administration after tPA inselect patients following mechanical thrombectomy warrants further study.

BACKGROUND: Reports of therapeutic drug monitoring (TDM) for second-line medications to treat multidrug-resistant tuberculosis (MDR-TB) remain limited. METHODS: A retrospective cohort from the Virginia state tuberculosis (TB) registry, 2009-2014, was analyzed for TDM usage in MDR-TB. Drug concentrations, measured at time of estimated peak (Cmax), were compared to expected ranges. RESULTS: Of 10 patients with MDR-TB, 8 (80%) had TDM for at least one drug (maximum 6 drugs). Second-line drugs tested were cycloserine in seven patients (mean C2hr, 16.6+/-10.2 microg/mL; 4 [57%] below expected range); moxifloxacin in five (mean C2hr, 3.2+/-1.5 microg/mL; 1 [20%] below); capreomycin in five (mean C2hr, 21.5+/-14.0 microg/mL; 3 [60%] below); para-aminosalicylic acid in five (mean C6hr, 65.0+/-29.1 microg/mL; all within or above); linezolid in three (mean C2hr, 11.4+/-4.1 microg/mL, 1 [33%] below); amikacin in two (mean C2hr, 35.3+/-3.7 microg/mL; 1 [50%] below); ethionamide in one (C2hr, 1.49 microg/mL, within expected). Two patients died: a 38-year-old woman with human immunodeficiency virus/acquired immune deficiency syndrome and TB meningitis without TDM, and a 76-year-old man with fluoroquinolone-resistant (pre-extensively drug-resistant) pulmonary TB and low linezolid and capreomycin concentrations. CONCLUSION: Individual pharmacokinetic variability was common. A more standardized approach to TDM for MDR-TB may limit over-testing and maximize therapeutic gain.

OBJECTIVE: To measure Irish opinion on a range of assisted human reproduction (AHR) treatments. METHODS: A nationally representative sample of Irish adults (n=1,003) were anonymously sampled by telephone survey. RESULTS: Most participants (77%) agreed that any fertility services offered internationally should also be available in Ireland, although only a small minority of the general Irish population had personal familiarity with AHR or infertility. This sample finds substantial agreement (63%) that the Government of Ireland should introduce legislation covering AHR. The range of support for gamete donation in Ireland ranged from 53% to 83%, depending on how donor privacy and disclosure policies are presented. For example, donation where the donor agrees to be contacted by the child born following donation, and anonymous donation where donor privacy is completely protected by law were supported by 68% and 66%, respectively. The least popular (53%) donor gamete treatment type appeared to be donation where the donor consents to be involved in the future life of any child born as a result of donor fertility treatment. Respondents in social class ABC1 (58%), age 18 to 24 (62%), age 25 to 34 (60%), or without children (61%) were more likely to favour this donor treatment policy in our sample. CONCLUSION: This is the first nationwide assessment of Irish public opinion on the advanced reproductive technologies since 2005. Access to a wide range of AHR treatment was supported by all subgroups studied. Public opinion concerning specific types of AHR treatment varied, yet general support for the need for national AHR legislation was reported by 63% of this national sample. Contemporary views on AHR remain largely consistent with the Commission for Assisted Human Reproduction recommendations from 2005, although further research is needed to clarify exactly how popular opinion on these issues has changed. It appears that legislation allowing for the full range of donation options (and not mandating disclosure of donor identity at a stipulated age) would better align with current Irish public opinion.
