Background: Hypertrophy of the adenoids is common in children. However, the anatomical site makes the adenoids difficult to assess, and studies evaluating the subject are ambiguous, especially with regard to the use of X-ray as an evaluation tool.

Objectives: To compare medical history with clinical, radiological, and endoscopic evaluations of the adenoids and compare obstructed and non-obstructed children relative to the assessment methods.

Methods: A prospective comparative study was conducted with children who were suspected of having enlarged adenoids. All parents completed a medical history questionnaire and patients underwent clinical evaluation based on Nasal Obstruction Index (NOI) scores, radiological assessment based on the lateral neck X-ray adenoid–nasopharynx (A/N( ratio, and endoscopic evaluation based on anatomical relations. Spearman correlations were used for comparison between methods.

Results: We evaluated 36 patients, median age 5.33 years. Correlation measurements for clinical assessment and questionnaire (r = 0.582, P < 0.0001), questionnaire and endoscopy (r = 0.462, P = 0.005), and clinical assessment and nasal endoscopy (r = 0.621, P < 0.0001) were statistically significant. None of the parameters correlated with the radiological findings. A statistically significant difference was found between the obstructed and non-obstructed groups in both questionnaire (P = 0.004) and clinical assessment (P < 0.0001). However, no difference was found in X-ray measurements.

Conclusions: Lateral neck X-ray measurements were not correlated to symptoms, signs, or endoscopic findings. Therefore, medical professionals should use lateral neck radiography when considering adenoidectomy only on a highly selective basis.

Background: Malignancy is a known risk factor for venous thromboembolism; however, the association with arterial thromboembolic events remains unclear.

Objectives: To examine the association between non-ST-elevation myocardial infarction (NSTEMI) and non-significant coronary artery disease (CAD) and the presence of new or occult malignancy.

Methods: An observational cohort, single-center study was performed 2010–2015. Adult patients with NSTEMI, who underwent coronary angiography and had no significant coronary lesion, were included. Using propensity score matching, we created a 2:1 matched control group of adults with NSTEMI, and significant coronary artery disease. Risk factors for new or occult malignancy were assessed using multivariate backward stepwise logistic regression analysis. The primary outcome was new or occult malignancy, defined as any malignancy diagnosed in the 3 months prior and 6 months following the myocardial infarction (MI).

Results: During the study period, 174 patients who presented with MI with non-obstructive coronary arteries were identified. The matched control group included 348 patients. There was no significant difference in the group demographics, past medical history, or clinical presentation. The incidence of new or occult malignancy in the study group was significantly higher (7/174, 4% vs. 3/348, 0.9%, P = 0.019). NSTEMI with non-significant CAD was an independent risk factor for occult malignancy (odds ratio [OR] 4.6, 95% confidence interval [95%CI] 1.1–18.7). Other risk factors included active smoking (OR 11.2, 95%CI 2.5–49.1) and age (OR 1.1, 95%CI 1.03–1.17).

Conclusions: NSTEMI with non-significant CAD may be a presenting or early marker of malignancy and warrants further investigation.

Background: The MitraClip procedure is becoming an acceptable alternative for high-risk patients with mitral regurgitation (MR) due to functional (FMR) or degenerative (DMR) disease and suitable mitral anatomy.

Objectives: To evaluate the results of MitraClip at our institute in carefully selected patients.

Methods: We conducted a retrospective analysis of medical records and echocardiography data from January 2012 to December 2017.

Results: A total of 39 MitraClip procedures in 37 patients (aged 75 ± 12 years, 9 women) was performed. Twenty-four patients presented with FMR, 12 with DMR, and 1 with combined pathology. One-day post-procedure MR was moderate to low in 86.1% of patients, with immediate device success in 88.8%. MR at 1 year was moderate to low in 79% at 1 year. Survival at 1 year was 86% and at 2 years 69.4%. Peri-procedural (< 1 week) death and MitraClip failure occurred in one and three patients, respectively. New York Heart Association score improved to class 1 or 2 in 37% of patients at 1 year vs. one patient at baseline. Post-procedural systolic pulmonary pressure was reduced from 53 (range 48–65) to 43 (range 36–52) mmHg at 1 month with a subsequent plateau at follow-up, to 41 (34–57) mmHg at 6 months, and to 47 (38–50) at 12 months.

Conclusions: MitraClip in severe MR resulted in modest improvement in functional status and pulmonary pressure with a small risk of immediate procedural complications. Outcomes are encouraging considering the natural course of MR and the risks of surgical intervention.

Background: Access-site bleeding is a common complication of transfemoral transcatheter aortic valve implantation (TAVI). Percutaneous stent-graft implantation within the femoral artery may achieve hemostasis and avert the need for more invasive surgical vascular repair; however, failure to advance a guidewire antegradely via the injured vessel may preclude stent delivery. While retrograde stent-graft delivery from the distal vasculature may potentially enable percutaneous control of bleeding, this approach has not been reported.

Objectives: To assess the feasibility of a retrograde approach for stent-graft implantation in the treatment of access-site bleeding following transfemoral TAVI.

Methods: A prospective TAVI registry was analyzed. Of 349 patients who underwent TAVI, transfemoral access was used in 332 (95%). Access-site injury requiring stent-graft implantation occurred in 56 (17%). In four patients (7%), antegrade wiring across the site of vascular injury was not possible and a retrograde approach for stent delivery was used.

Results: Distal vascular access was achieved via the superficial femoral or profunda artery. Retrograde advancement of a polymer-coated 0.035” wire to the abdominal aorta, followed by stent-graft delivery to the common femoral artery, achieved hemostasis in all cases. During a median (interquartile range) follow-up period of 198 (618) days (range 46–2455) there were no deaths and no patient required additional vascular interventions.

Conclusions: A retrograde approach for stent-graft delivery is feasible and allows percutaneous treatment of a common femoral artery injury following TAVI in patients who are not suitable for the conventional antegrade approach.

Background: Pulmonary rehabilitation has shown significant benefit for patients with chronic obstructive pulmonary disease (COPD). The effect on non-COPD pulmonary patients is less well established.

Objectives: To determine whether pulmonary rehabilitation is also beneficial for non-COPD pulmonary patients.

Methods: Clinical and demographic data on non-COPD pulmonary patients who participated in our institutional pulmonary rehabilitation program between January 2009 and December 2016 were collected. Participants engaged in a 60-minute, twice-weekly, ambulatory hospital-based program lasting 12 to 24 sessions. Sessions included both endurance and muscle training as well as healthy lifestyle educational activities. The six-minute walk test (6MWT) and the St. George's Respiratory Questionnaire (SGRQ) were conducted before and after the rehabilitation program.

Result: We recruited 214 non-COPD patients, of whom 153 completed at least 12 sessions. Of these, 59 presented with interstitial lung disease (ILD), 18 with non-ILD restrictive lung defects, 25 with asthma, 30 with lung cancer, and 21 with other conditions (e.g., pulmonary hypertension, bronchiectasis) The groups demonstrated significant improvement in 6MWT and in SGRQ scores. Non-COPD patients gained a 61.9 meter (19%) improvement in the 6MWT (P < 0.0001) and 8.3 point reduction in their SGRQ score (P < 0.0001).

Conclusions: Pulmonary rehabilitation is effective in non-COPD pulmonary patients. As such, it should be an integral part of the treatment armament provided to the vast majority of those suffering from chronic respiratory disease.

Angiogenesis is the outgrowth of new blood vessels from existing ones and is an early occurrence in inflamed joint tissue. It is governed by a tightly controlled balance of pro- and anti-angiogenic stimuli, which promote or inhibit generation and proliferation of new endothelial cells, vascular morphogenesis, and vessel remodeling. At the beginning, capillary formation is crucial in maintaining the supply of various nutrients as well as oxygen to the inflamed tissue. Local and systemic expression of angiogenic factors may indicate a constant remodeling of synovial vasculature. Redox signaling is closely related to angiogenesis and can alter angiogenic responses of synovial cells. In this review we discuss key issues about the endothelial pathology in inflammatory arthritis followed by a review of angiogenic processes and main angiogenic mediators. We discuss the hypoxia-vascular endothelial growth factor (VEGF)-Ang/Tie2 system and its related therapeutic implications in detail with further review of various mediator protein targets and intracellular regulatory pathway targets with their current and potential future role in preclinical or clinical setting whilst ameliorating inflammation.

Background: When a woman with an endometrioma presents with acute abdominal pain, it is unclear whether ovarian torsion should be suspected.

Objectives: To compare patient characteristics, imaging results, and surgical management of endometriomas in elective versus emergent surgeries.

Methods: This retrospective cohort study included women treated at our institution during the period 1990–2015 who presented with histologically verified endometrioma and who underwent either planned surgery or emergent surgery due to suspected adnexal torsion.

Results: Of 225 surgeries performed, 174 were elective and 51 emergent. Patients in the emergent group were significantly younger (33.9 ± 11.1 vs. 39.01 ± 10.9 years, P = 0.004). Abdominal pain was the main complaint of all the emergent surgery patients and the leading complaint in 21% of the elective surgery patients (P < 0.001), with right-sided predominance in both groups. Sonographic parameters were similar in both groups. Bilateral ovarian cysts were noted in 11.7% and 11.0% of emergent and elective patients, respectively (P = 0.87). Laboratory evaluation was notable for a higher white blood cell count and CA125 levels among emergent patients. All patients in the emergent group and 93% of patients in the elective group were managed laparoscopically. No cases of torsion were noted. The rate of intra-pelvic adhesions was similar in both groups (56.8% vs. 66.6%, P = 0.19).

Conclusions: Endometrioma may present with acute abdominal pain. However, adnexal torsion in these patients is rare. These cases can be managed using a minimally invasive approach, assuming an optimal surgical setting.
