Background: When a breast lesion is suspected based on a physical exam, mammography, or ultrasound, a stereotactic core needle biopsy (CNB) is usually performed to help establish a definitive diagnosis. CNBs are far less invasive than excisional biopsies, with no need for general anesthetics or hospitalization, and no recovery period. However, since only samples of the mass are removed in a CNB and not the whole mass, sampling errors can occur.
Objectives: To compare the degree of agreement between the pathological data from CNBs and excisional biopsies from a single tertiary referral hospital.
Methods: The concordance of pathological data was compared in patients who underwent CNBs and had their surgical procedures at the same medical center.
Results: From the 894 patients who underwent CNBs, 254 (28.4%) underwent subsequent excisional biopsies at our medical center. From the total of 894 patients, 227 (25.3%) who underwent a CNB were diagnosed with a malignancy, with the rest of the CNBs being diagnosed as benign pathologies. The pathological findings in the CNBs and in the excisional biopsies concurred in 232/254 (91.3%) of the cases.
Conclusions: A CNB to confirm mammographic or clinical findings of breast lesions is an accurate method to establish a pathological diagnosis of breast lesions. The accuracy is higher for invasive carcinomas than for non-invasive cancers. Excisional biopsies are necessary for lesions with anticipated sampling errors or when the core needle biopsy findings are discordant with clinical or mammographic findings.

Background: Anemia management strategies among chronic hemodialysis patients with high ferritin levels remains challenging for nephrologists.
Objectives: To compare anemia management in stable hemodialysis patients with high (≥ 500 ng/ml) vs. low (< 500 ng/ml) ferritin levels
Methods: In a single center, record review, cohort study of stable hemodialysis patients who were followed for 24 months, an anemia management policy was amended to discontinue intravenous (IV) iron therapy for stable hemodialysis patients with hemoglobin > 10 g/dl and ferritin ≥ 500 ng/ml. Erythropoiesis-stimulating-agents (ESA), IV iron doses, and laboratory parameters were compared among patients with high vs. low baseline ferritin levels before and after IV iron cessation.
Results: Among 87 patients, 73.6% had baseline ferritin ≥ 500 ng/ml. Weekly ESA dose was greater among patients with high vs. low ferritin (6788.8 ± 4727.8 IU/week vs. 3305.0 ± 2953.9 IU/week, P = 0.001); whereas, cumulative and monthly IV iron doses were significantly lower (1628.2 ± 1491.1 mg vs. 2557.4 ± 1398.9 mg, P = 0.011, and 82.9 ± 85 vs. 140.7 ± 63.9 mg, P = 0.004). Among patients with high ferritin, IV iron was discontinued for more than 3 months in 41 patients (64%) and completely avoided in 6 (9.5%).ESA dose and hemoglobin levels did not change significantly during this period.
Conclusions: Iron cessation in chronic hemodialysis patients with high ferritin levels did not affect hemoglobin level or ESA dose and can be considered as a safe policy for attenuating the risk of chronic iron overload.

Background: Abnormal gestational weight gain (GWG) has been associated with adverse outcomes for mothers and their offspring.
Objectives: To compare the achievement of recommended GWG and lifestyle factors in women with high-risk versus normal-risk pregnancies.
Methods: Pregnant women hospitalized in a gynecological and obstetrics department and pregnant women who arrived at a community clinic for a routine checkup were interviewed and completed questionnaires relating to weight gain and lifestyle factors (e.g., smoking, diet, exercise). Recommended GWG was defined by the American Congress of Obstetricians and Gynecologists (ACOG).
Results: GWG higher than ACOG recommendations was reported by 52/92 women (57%) with normal pregnancies and by 43/86 (50%) with high-risk pregnancies. On univariate analysis, characteristics associated with greater GWG were: current or past smoking, age > 40 years, pre-gestational body mass index (BMI) > 25 kg/m2, low fruit intake, and high snack intake. High-risk pregnancies were associated with pre-gestational BMI > 25 kg/m2 (48% vs. 27%, P = 0.012), consumption of vitamins (84% vs. 63%, P = 0.001), avoidance of certain foods (54% vs. 21%, P = 0.015), receiving professional nutritionist consultation (65% vs. 11%, P = 0.001), and less physical activity (9% vs. 24%, P = 0.01).
Conclusions: A minority of pregnant women met the recommended GWG. No difference was noted between normal and high-risk pregnancies. High-risk population tended to have a less healthy lifestyle. Counseling to follow a healthy, balanced diet should be recommended, regardless of pregnancy risk, with particular attention to women at high risk of extra weight gain.

Background: Family physicians and internal medicine specialists play an essential role in treating cancer patients. Modern technological advances in radiotherapy are not widely appreciated by primary care physicians. Bone metastases are a frequent complication of cancer. Palliative radiation therapy, as a component of modern advances in radiation treatments, should not subject normal bodily structures to excessive doses of irradiation. The sacrum is a common destination site for bone metastases, yet its concave shape along with its proximity to the rectum, intestines, and femoral heads creates treatment-planning challenges.
Objectives: To investigated whether the volumetric modulated arc therapy (VMAT) technique is preferable to more conventional radiation strategies.
Methods: The study comprised 22 patients with sacral metastases who were consecutively treated between 2013 and 2014. Two plans were generated for the comparison: three-dimensional (3D) and VMAT.
Results: The planning target volume (PTV) coverage of the sacrum was identical in VMAT and 3D planning. The median values for the rectal dose for 3D and VMAT were 11.34 ± 5.14 Gy and 7.7 ± 2.76 Gy, respectively. Distal sacral involvement (S4 and S5) was observed in only 2 of 22 cases, while the upper pole of the rectum ended at the level above S3 in just 3 cases.
Conclusions: Radiation therapy continues to be an integral component of the palliative armamentarium against painful metastases. Radiation oncologist, in conjunction with referral physicians, can tailor treatment plans to reflect the needs of a given patient.

Background: A patient`s individual chance of being diagnosed with cardiovascular disease can be determined by risk scores.
Objectives: To determine the risk score profiles of patients presenting with a first acute coronary event according to pre-admission risk factors and to evaluate its association with long-term mortality.
Methods: The research was based on a retrospective study of a cohort from the 2010 and 2013 Acute Coronary Syndrome Israeli Surveys (ACSIS). Inclusion criteria included first event and no history of coronary heart disease or cardiovascular disease risk equivalent. The Framingham Risk Score, the European Systematic COronary Risk Evaluation (SCORE), and the American College of Cardiology/American Heart Association/ (ACC/AHA) risk calculator were computed for each patient. The risk profile of each patients was determined by the three scores. The prognostic value of each score for 5 year survival was evaluated.
Results: The study population comprised 1338 patients enrolled in the prospective ACSIS survey. The ACC/AHA score was the most accurate in identifying patients as high risk based on pre-admission risk factors (73% of the subjects). The Framingham algorithm identified 53%, whereas SCORE recognized only 4%. After multivariate adjustment for clinical factors at presentation, we found that no scores were independently associated with 5 year mortality following the first acute coronary event.
Conclusions: Patients with first acute coronary event had a higher pre-admission risk scores according to the ACC/AHA risk algorithm. No risk scores were independently associated with 5 year survival after an event.

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: A dental appliance for obstructive sleep apnea (OSA) is recommended for patients who cannot adjust to continuous positive airway pressure (CPAP) treatments.
Objectives: To describe patients with extremely severe OSA who were successfully treated with a dental appliance and to compare their characteristics with the relevant literature to identify clinical features associated with a good outcome.
Methods: The clinical, management, and outcome data of three patients with an apnea-hypopnea index (AHI) of > 80 who showed clinical improvement following treatment with a dental appliance were collected retrospectively from sleep laboratory reports in Israel over a period of 3 years.
Results: The patients included one man and two women, aged 33, 56, and 61 years, respectively. The diagnosis of OSA was based on clinical examination and polysomnography. AHI values at presentation were 83, 81, and 84, respectively. Treatment with a dental appliance (Herbst® or MDSA®) was proposed due to patient noncompliance with CPAP. Follow-up polysomnography with the dental appliance revealed a reduction in the AHI to 1.7, 10.7, and 11, respectively. All patients had supine OSA and a retrognathic mandible, both of which have been found to be associated with a good prognosis for treatment with a dental appliance.
Conclusions: Dental appliances may be considered an appropriate second-choice option to treat severe OSA in patients who are noncompliant with CPAP. This study helps physicians identify patients with extremely severe OSA who are suitable for dental appliance treatment. Well-designed large-scale studies are needed to reach definitive conclusions.

Background: Skin colonization of microorganisms in blood cultures (BCs) are generally considered clinically non-significant and can be the source of a true infection, particularly in immunosuppressed patients.
Objectives: To study the epidemiology and risk factors for bacteremia caused by contaminants.
Methods: This retrospective, descriptive study is based on adult BCs collected (2004–2013) and categorized as positive (True bacteremia [TrueB] or contamination) or negative. Clinical, demographic, and laboratory characteristics of BCs positive for the six most common potential contaminant pathogens (PCPs) that can cause TrueB and contamination (Coagulase-negative Staphylococcus [CoNS], Streptococcus viridans, Propionibacterium acnes, Corynebacterium spp., Bacillus spp., Clostridium spp.) were assessed. Ninety-two TrueB were identified vs. 196 contaminations (1:2 ratio).
Results: From 74,014 BCs, PCPs were found in 3735 samples, of which 3643 (97.5%) were contaminations and 92 (2.5%) were TrueB. The overall rate of BC contamination decreased during the study period from 6.7% to 3.8%. CoNS was the most common PCP. Bacillus spp. were only contaminants. Clostridium spp. and Streptococcus viridans were more often TrueB. In a multivariate model, predictors of TrueB included high creatinine levels, Streptococcus viridans in BC, and multiple positive BCs. A single culture of CoNS was strongly predictive of contamination.
Conclusions: Ten years of data on BCs, focusing on six PCPs, demonstrates a significant, yet insufficient reduction in the rate of contamination. High creatinine level, isolation of Streptococcus viridans, and multiple positive BCs were predictors of TrueB, while growth of CoNS was strongly predictive of contamination. This model could assist in diagnostic and therapeutic decision making.

Background: Clinical research is needed to identify patients with axial spondyloarthritis (axSpA) who are more likely to be responsive to interleukin (IL)-17 inhibition.
Objectives: To evaluate short-term efficacy of secukinumab in the management of axSpA.
Method: Twenty-one patients (7 males, 14 females) with axSpA were consecutively treated with secukinumab. Laboratory and clinical assessments were based on erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Ankylosing Spondylitis Disease Activity Score (ASDAS)-CRP, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Data were recorded at baseline and at a 3 month follow-up visit.
Results: The study was comprised of 21 patients. Both BASDAI and ASDAS-CRP showed a statistically significant reduction between the baseline and the 3 month visit (P < 0.0001 and P = 0.0005, respectively). During the laboratory assessment, ESR showed a significant decrease (P = 0.008) while CRP improvement did not reach statistical significance (P = 0.213). No statistical significance was observed between patients treated with secukinumab 150 mg vs. 300 mg in BASDAI (P=0.99), ASDAS-CRP (P = 0.69), ESR (P = 0.54), and CRP (P = 0.56). No significant differences emerged between the BASDAI (P = 0.15), ASDAS-CRP (P = 0.09), and CRP (P = 0.15) rates in biologic-naïve patients and those previously failing tumor necrosis factor-α inhibition. Conversely, ESR decrease was significantly higher in the biologic-naïve subgroup (P = 0.01). No adverse events were reported.
Conclusions: Secukinumab has proven remarkable short-term effectiveness, regardless of the biologic treatment line. A dosage of 150 mg proved to be appropriate in the clinical and laboratory management of axSpA.

Background: Supracondylar humerus fractures are the most common elbow fractures in the pediatric population.
Objectives: To evaluate the outcomes of French's corrective osteotomy for correction of post-traumatic cubitus varus deformity in children.
Method: We conducted a retrospective review of medical charts of all patients who had undergone French's corrective osteotomy in our institution from 1998 to 2012. We recorded range of motion, cosmetic deformity, carrying angle, lateral cortex prominence index, hyperextension, and lateral cortex step before and after the surgery.
Results: Seven patients were enrolled the study. Average follow-up time was 4.6 years (range 2–9 years). An average of 18.3º of limited flexion (range 5º–35º) compared to the healthy elbow was recorded in three patients. Lateral condylar prominence was recorded in one patient. The average preoperative carrying angle was -20.5º (range -15º–30º) and postoperative angle was 9.6º (range 7º–13º). In comparison, the average carrying angle in the healthy elbow was 8.5º (range 4º–13º). No lateral cortex prominence was recorded. An average of 27.5º (range 15º–35º) of hyperextension of the distal fragment was recorded immediately postoperatively in four patients; however, during postoperative follow-up, the hyperextension was corrected spontaneously in all patients.
Conclusions: As described by French, osteotomy has the ability to correct the varus deformity only in the coronal plane. However, our research supports the assumption that hyperextension in the sagittal plane might be corrected spontaneously.
