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: Hysterectomy is common in the management of symptomatic uterine prolapse. Vaginal wall repair is often necessary, for which vaginal mesh remains a popular option.

Objectives: To evaluate the risk of mesh erosion following mesh-augmented vaginal prolapse repair, with or without concomitant vaginal hysterectomy.

Methods: This retrospective cohort comprised 70 women who underwent vaginal mesh-augmented pelvic organ prolapse repair from 2007 to 2010. Of the participants, 36 (51.4%) had a vaginal hysterectomy concomitant to the anterior and/or posterior vaginal mesh repair (hysterectomy group) and 34 (48.6%) underwent mesh repair without vaginal hysterectomy (no hysterectomy group).

Results: There were no inter-group differences in age, parity, menopausal state, hormonal use, or presenting symptoms. Previous prolapse repair surgery was much more common in the no hysterectomy group (29.4% vs. 5.5%, P = 0.01). Eleven patients (32.3%) in the no hysterectomy group had previously undergone hysterectomy. Anterior mesh repair was performed in 77.7% and 67.6% of hysterectomy and no hysterectomy patients, respectively. Posterior mesh repair was performed in 27.7% and 44.1%, respectively. One patient in the hysterectomy group underwent immediate removal of mesh due to infection. Surgically treated mesh erosion (limited local excision) occurred in three patients (8.3%) in the hysterectomy group (3, 16, and 18 months following surgery) and in two patients (5.8%) in the no hysterectomy group at 6 months following surgery (P = 0.67).

Conclusions: Vaginal mesh-augmentation concomitant with vaginal hysterectomy for pelvic organ prolapse repair does not carry an increased risk of erosion.

Background: There are several methods for primary breast reconstruction following oncologic resection, including alloplastic and autologous-based reconstruction. Major complications that can lead to re-operation and reconstruction failure occur in up to 25% of the patients and necessitate salvage procedures.

Objectives: To present the authors' experience using a pedicled latissimus dorsi (LD) flap for the salvage of complicated and impending failed breast reconstruction.

Methods: A retrospective cohort study was conducted of all patients who underwent breast reconstruction salvage by means of an LD flap in our institution during a 5-year period. Demographic, oncologic, surgical, and postoperative data were collected and analyzed.

Results: Seventeen patients underwent breast reconstruction salvage with the LD flap. Fourteen patients had alloplastic reconstruction and three patients had autologous reconstruction. Postoperative complications included wound infection in three patients, minor wound dehiscence in two, and donor site seroma in two. One case of postoperative infection required re-operation with exchange of the implant with a tissue expander. All breast reconstructions were salvaged using the LD flap. Only one patient complained of functional limitations in using the arm of the harvested LD.

Conclusions: The LD flap is a valuable and reliable flap for alloplastic or autologous breast reconstruction salvage and has a high rate of salvage success despite the challenging surgical environment. This flap offers a good cosmetic reconstruction outcome with relatively low donor-site morbidity and high patient satisfaction.

Background: Unicuspid and bicuspid aortic valve (BAV) are congenital cardiac anomalies associated with valvular dysfunction and aortopathies occurring at a young age.

Objectives: To evaluate our experience with aortic valve repair (AVr) in patients with bicuspid or unicuspid aortic valves.

Methods: Eighty patients with BAV or unicuspid aortic valve (UAV) underwent AVr. Mean patient age was 42 ± 14 years and 94% were male. Surgical technique included: aortic root replacement with or without cusp repair in 43 patients (53%), replacement of the ascending aorta at the height of the sino-tubular junction with or without cusp repair in 15 patients (19%), and isolated cusp repair in 22 patients (28%).

Results: The anatomical structure of the aortic valve was bicuspid in 68 (85%) and unicuspid in 12 patients (15%). Survival rate was 100% at 5 years of follow-up. Eleven patients (13.7%) underwent reoperation, 8 of whom presented with recurrent symptomatic aortic insufficiency (AI). Late echocardiography in the remaining 69 patients revealed mild AI in 63 patients, moderate recurrent AI in 4, and severe recurrent AI in 2. Relief from recurrent severe AI or reoperations was significantly lower in patients who underwent cusp repair compared with those who did not (P = 0.05). Furthermore, the use of pericardial patch augmentation for the repair was a predictor for recurrence (P = 0.05).

Conclusions: AVr in patients with BAV or UAV is a safe procedure with low morbidity and mortality rates. The use of a pericardial patch augmentation was associated with higher repair failure.

Background: When a patient arrives at the emergency department (ED) presenting with symptoms of acute decompensated heart failure (ADHF), it is possible to reach a definitive diagnosis through many different venues, including medical history, physical examination, echocardiography, chest X-ray, and B-type natriuretic peptide (BNP) levels. Point-of-care ultrasound (POCUS) has become a mainstream tool for diagnosis and treatment in the field of emergency medicine, as well as in various other departments in the hospital setting. Currently, the main methods of diagnosis of ADHF using POCUS are pleural B-lines and inferior vena cava (IVC) width and respiratory variation.

Objectives: To examine the potential use and benefits of bedside ultrasound of the jugular veins in the evaluation of dyspneic patients for identification of ADHF.

Methods: A blood BNP level was drawn from each participant at time of recruitment. The area and size of the internal jugular vein (IJV) during inspiration and expiration were examined.

Results: Our results showed that the respiratory area change of the IJVs had a specificity and sensitivity of nearly 70% accuracy rate in indentifying ADHF in our ED.

Conclusions: Ultrasound of the IJV may be a useful tool for the diagnosis of ADHF because it is easy to measure and requires little skill. It is also not affected by patient body habitus.

Background: Sonographic assessment of the fetal kidneys is an integral part of the prenatal anatomical survey.

Objectives: To evaluate the fetal renal to abdominal (RTA) ratio throughout pregnancy and to investigate whether this ratio can be a potential diagnostic landmark for congenital anomalies of the kidney and urinary tract (CAKUT).

Methods: Measurements of the anterior-posterior diameters of the fetal kidney and fetal abdomen (APAD) were obtained prospectively. The RTA was calculated as the ratio between them in in two groups: normal population vs. CAKUT cases. RTA in CAKUT cases was compared to RTA in a normal population.

Results: The study group was comprised of 210 women. The mean gestational age for the fetuses was 31 ± 5.6 weeks (range 14–40 weeks). Fetal RTA ratio was found to be 0.28 ± 0.03 throughout pregnancy from early second trimester to term, with high reproducibility of measurements. During the study period the RTA was evaluated in nine cases referred for suspected CAKUT. All cases demonstrated a different ratio according to the renal anomaly. High ratio was observed in one case of overgrowth syndrome (Beckwith Wiedenmann syndrome; 0.47), three cases of infantile polycystic kidney (0.45–0.47), and three cases of a solitary kidney (0.31–0.35), while cases of dysplastic kidneys revealed a low ratio (0.14–0.18).

Conclusions: Prenatal RTA ratio is constant throughout gestation. An abnormal ratio should lead to meticulous renal investigation to rule out kidney disease.

Background: The estimated incidence of esophageal atresia (EA) with or without tracheo-esophageal fistula (TEF) is 1:3500 live births. During childhood these patients have various co-morbidities, but the overall quality of life among adults is similar to that of the general population.

Objectives: To evaluate short- and long-term co-morbidities and quality of life among infants born with EA ± TEF at a large single medical center.

Methods: Medical records of 65 children born over a 21 year period were reviewed for short- and long-term medical data. Telephone interviews were conducted with 46 of their parents regarding medical problems and quality of life after home discharge.

Results: The main long-term co-morbidities during the first 2 years of life, 4–6 years of age, and during adolescence (12–16 years) included gastro-esophageal reflux disease (GERD) in 56.5%, 35.8%, and 18.7%, respectively; stridor in 84.8%, 45.2%, and 12.5%, respectively; hyper-reactive airway disease (HRAD) in 43.5%, 35.5%, and 36.5%, respectively; recurrent pneumonia in 43.5%, 32.3%, and 18.8%, respectively; and overall recurrent hospitalizations in 87%, 41.9%, and 25%, respectively. The quality of life was reportedly affected among 100%, 75%, and 33.3% respectively.

Conclusions: Long-term follow-up of patients with EA ± TEF indicates a high burden of co-morbidities during the first 6 years of life, with a gradual decrease in symptoms thereafter. Nevertheless, HRAD continued to impact the daily life of about one-third of the older adolescents, and GERD one-fifth. A long-term multidisciplinary follow-up should be conducted to prevent late onset complications that may affect the quality of life.

Background: Previous surveys demonstrated variations in the clinical practices relating to the treatment and screening of maternal thyroid dysfunction.

Objectives: To study the current practices in the management of subclinical hypothyroidism (SCH) and thyroid nodules during pregnancy of obstetricians/gynecologists (OB/GYNs) and endocrinologists in Israel.

Methods: An electronic questionnaire was sent by email to all members of the Israeli Endocrine Society and the Israel Society of Obstetrics and Gynecology. Questionnaires included demographic data and clinical scenarios with questions regarding the screening and management of pregnant women with SCH, hypothyroxinemia, and a palpable thyroid nodule. The questionnaire for OB/GYNs was slightly modified.

Results: We received 90 responses from endocrinologists and 42 responses from OB/GYNs. Among endocrinologists, 39% would repeat a thyroid-stimulating hormone (TSH) test of 2.9 mU/L with normal free thyroxine and treat with thyroxine if the second result was above 2.5 mU/L. Among OB/GYNs, 73% would manage a woman with SCH at the beginning of her pregnancy by themselves and only 22% would start thyroxine after a first TSH result above 2.5 mU/L. Concerning screening, 57% endocrinologists and 71% OB/GYNs recommended screening for thyroid dysfunction in every woman at the beginning of her pregnancy. Among endocrinologists, 54% would order an ultrasound for a palpable thyroid nodule and perform a fine needle aspiration only for suspicious lesions.

Conclusions: The medical approach to thyroid disease in pregnant women remains a matter of controversy. Our results support the need for larger and prospective clinical studies.
