Characterization of Pulmonary Emboli in Total Joint Arthroplasty Patients Compared to General Medical Patients
J Knee Surg DOI: 10.1055/s-0039-1693417Pulmonary emboli (PEs) occur in medical and postoperative total joint arthroplasty (TJA) patients. These are different patient populations, yet both undergo identical diagnosis and treatment regardless of PEs size and quantity. To date, there has been no analysis of the location, size, and quantity of emboli that occur postoperatively in TJA compared with general medical patients. We hypothesized TJA patients would have different size and distribution of PEs per event compared with medical patients. A retrospective chart review was conducted of patients who underwent total hip or knee arthroplasty in comparison to general medical patients at our institution from 2006 to 2011 with a PE diagnosis. Medical co-morbidities, sex, age, procedure, postoperative day, size, and location of PE using spiral computed tomography were recorded using a novel mapping scheme. Embolus size was defined based on blockage level in the pulmonary arterial tree. Of the 4,178 TJA patients reviewed, 51 were diagnosed with a PE. A total of 67% of TJA patients were women, yet women represented 90% (n = 46) of TJA PE patients (p
CONCLUSIONS: The analysis of internal anatomy using CBCT revealed a highly variable distribution of root canals. The most frequent morphology found in mandibular molars in a Chilean population was two roots and three canals. PMID: 31322722 [PubMed - as supplied by publisher]
Authors: Andrade VM, Fontenele RC, Souza AC, Almeida CA, Vieira AC, Groppo FC, Freitas DQ, Junior ED Abstract OBJECTIVES: To develop and validate formulas for age and sex estimation based on the pulp cavity volume of teeth using cone-beam computed tomography (CBCT). METHODS: The sample was composed of 116 CBCT scans from Brazilian individuals of both sexes, ranging in age from 13 to 70 years. A total of 232 teeth (upper central incisors and canines) were evaluated. Two calibrated examiners determined pulp cavity volumes using the ITK-SNAP software. Pearson's correlation test was used to assess the correlation b...
As I age, the probability of acquiring yet another health condition seems to, unfortunately, increase. There’s always one test or another that is on my to-do list, be it bloodwork, X-ray, MRI, or maybe a CT scan thrown in for good measure. I comply usually with a sense that it is for the benefit of […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more.
ConclusionA high index of suspicion, coupled with a tailored, multidisciplinary approach, is essential to achieve the best possible outcome. Conservative management may be worthwhile in a stable patient despite delayed presentation. Although TOE is considered a safe procedure, physicians should be made aware of such a dreaded complication.

Left-sided diaphragmatic injuries are more commonly reported in literature. Bilateral injuries are extremely rare, occurring in about 3% of the patients and just few cases reported in literature. Traumatic diaphragmatic hernias are definitely a m...
ConclusionPrimary retoperitoneal mucinous cystadenoma is a rare clinical entity that is usually incidentally discovered. Laparoscopic excision is safe and feasible if done by an expert laparoscopic surgeon. Care should always be taken not to cause spillage of its content.
ConclusionThere is some previous caution in using a laparoscopic approach for cystic masses due to potential seeding intra-operatively, in case of fluid spillage of a possible malignant neoplasm. We show through our case that it is possible to efficiently and safely use such an approach.
ConclusionVariations in mesenchymal gastrointestinal tumors is vast, rendering diagnosis by radiology alone difficult. As such, characteristic histologic and immunostaining features are cornerstones in precise diagnosis of esophageal schwannomas. Despite being rare in incidence, symptomatic esophageal schwannoma lesions can be excised entirely, with low rate of recurrence and favorable overall outcomes.

We explored the feasibility of using radiomics to preoperatively predict cervical LN metastasis in PTC patients.MethodTotal 221 PTC patients (training cohort: n = 154; validation cohort: n = 67; divided randomly at the ratio of 7:3) were enrolled and di...
ConclusionsThe TS CT may be useful to detect vertebral metastases because almost all the vertebral metastases were shown to be favorable visualization. The TS CT was proven to be especially helpful for radiology residents in detecting vertebral arch metastases.
