Utility of Cardiac Compute Tomography in Patients with Left Ventricular Assist Devices
AbstractPurpose of ReviewThe number of left ventricular assist device implants has increased significantly in the last decade. Left ventricular assist device (LVAD) optimization, trouble-shooting complications, and surgical planning require a multi-modality imaging approach. Echocardiography remains the imaging modality of choice, particularly for physiological evaluation but accurate anatomical evaluation of the entirety of the LVAD is often challenging if not impossible. Cardiac computed tomography (CCT) offers additional information that is valuable in taking care of these complex patients. The purpose of this review is to understand the nuances of LVAD imaging and areas where CCT can aid LVAD evaluation and management.Recent FindingsCCT has a well-established role in trouble-shooting complications particularly inflow and outflow cannula-related anatomic complications from suction and kinking. Even though the literature is scarce, there is evolving data to suggest that adverse inflow and outflow cannula positions may result in unfavorable outcomes. There is more interest in novel mechanisms of device implantation and planning for which data set from CCT is ideal. Functional evaluation of the right ventricle with CCT is becoming more sophisticated and maybe particularly useful in this patient population. Development in CCT technology has helped minimize safety concerns and improved image quality with reduction in LVAD-related artifacts.SummaryCCT is an important adjunct mod...
ConclusionIP is a diagnosis of exclusion which should only be made after surgical and non-surgical causes have been outruled. In the absence of signs of peritonitis and evidence of gastrointestinal perforation on CT, a conservative approach is warranted, allowing patients to avoid unnecessary surgical intervention.
CONCLUSIONTc-99 m SC SPECT-CT is a novel helper used to assess the differential liver function after Y90 radioembolization of HCC and before segmentectomy and lobectomy of the liver.
ConclusionThis report described the presentation and treatment of a chronic S. marcescens sternal abscess that occurred 13 years after CABG. Chronic sternal infections due to this organism in cardiac surgery patients are exceeding rare.
Authors: Bilezikian JP, Hattersley G, Mitlak BH, Hu MY, Fitzpatrick LA, Dabrowski C, Miller PD, Papapoulos SE Abstract Objective: To evaluate, post hoc, the efficacy and safety of abaloparatide by degree of renal impairment. Methods: ACTIVE was a phase 3, 18-month, randomized, double-blind, active-comparator, placebo-controlled study of postmenopausal women with osteoporosis who received subcutaneous abaloparatide 80 µg, placebo, or open-label teriparatide 20 µg daily. Patients with serum creatinine>2.0 mg/dL or 1.5-2.0 mg/dL with an estimated glomerular filtration rate (eGFR)
This report serves as a preliminary study and may be a surgical option for minimally invasive direct repair.
In conclusions, nicergoline appears to delay the speed of deterioration of cognitive function in patients with PDD based on our observation of decreased rCBF in the temporal regions and inferior frontal regions of PDD − N patients compared to PDD + N patients after 12-month of nicergoline therapy. Therefore, we cautiously suggest that nicergoline administration in PDD patients may slow progression of cognitive impairment in affected brain regions.
Conclusion: Preliminary results showed that the restoration of rostral CSF flow might result in an effective ITB treatment in patients with an intrathecal obstruction. PMID: 31418647 [PubMed - as supplied by publisher]
CONCLUSION: In peritoneal dialysis patients, spironolactone did not attenuate the progression of CC. However, large-scale studies are needed to confirm this observation. Disorders of mineral metabolism and dyslipidemia are involved in the progression of CC. PMID: 31419271 [PubMed - as supplied by publisher]

ReinholdAbstractUterine leiomyomas, the most frequent benign myomatous tumors of the uterus, often cannot be distinguished from malignant uterine leiomyosarcomas using clinical criteria. Furthermore, imaging differentiation between both entities is frequently challenging due to their potential overlapping features. Because a suspected leiomyoma is often managed conservatively or with minimally invasive treatments, the misdiagno...
ConclusionThe migrated IUD in the bladder was successfully and completely extracted by the method combining various endoscopes; operative time was 56 minutes. In the follow-up period the patient did not report any symptoms of frequency urination. This surgical process has the following characteristics: Preoperative examination should be performed to clarify the ectopic site of the IUD, various endoscopes should be combined for diagnosis and treatment, and endoscopic surgery is an effective treatment method for migrated IUD.
