Background: Evaluation of low rectal anastomosis is often recommended prior to ostomy closure, but the efficacy of such evaluations is uncertain.

Objectives: To assess whether routine colonic preoperative evaluation has an effect on postoperative ileostomy closure results.

Methods: We performed a retrospective study evaluating all patients who underwent ileostomy closure over 9 years. Patient demographics, clinical, surgical details, and surgical outcomes were recorded and analyzed.

Results: The study comprised 116 patients who underwent ileostomy closure, of them 65 were male (56%) with a mean age of 61 years (range 20–91). Overall, 98 patients (84.4%) underwent colonic preoperative evaluation prior to ileostomy closure. A contrast enema was performed on 61 patients (62.2%). Abnormal preoperative results were observed in 12 patients (12.2%). The overall complication rate was 35.3% (41 patients). No differences in postoperative outcome was observed in patient gender (P = 1), age (P = 0.96), body mass index (P = 0.24), American Society of Anesthesiologists score (P = 0.21), and the Charlson Comorbidity Index score (P = 0.93). Among patients who had postoperative complications, we did not observe a difference between patients who underwent preoperative evaluation compared to those who did not (P = 0.42). No differences were observed among patients with preoperative findings interpreted as normal or abnormal (P = 1). The time difference between ileostomy creation and closure had no effect on the ileostomy closure outcome (P = 0.34).

Conclusions: Abnormal findings in preoperative colonic evaluation prior to ileostomy closure were not associated with worse postoperative outcome.

Background: Anastomotic leakage (AL) is a major complication following colorectal surgery, with many risk factors established to date. The incidence of AL varies in the medical literature and is dependent on research inclusion criteria and diagnostic criteria.

Objectives: To determine the incidence of and the potential risk factors for AL following colorectal surgery at a single academic medical center.

Methods: We retrospectively reviewed all operative reports of colorectal procedures that included bowel resection and primary bowel anastomosis performed at Sheba Medical Center during 2012. AL was defined according to the 1991 United Kingdom Surgical Infection Study Group criteria. Data were assessed for leak incidence within 30 days. In addition, 17 possible risk factors for leakage were analyzed. A literature review was conducted.

Results: This cohort study comprised 260 patients, and included 261 procedures performed during the study period. The overall leak rate was 8.4%. In a univariate analysis, male sex (odds ratio [OR] 3.37, 95% confidence interval [95%CI] 1.21–9.43), pulmonary disease (OR 3.99, 95%CI 1.49–10.73), current or past smoking (OR 2.93, 95%CI 1.21–7.10), and American Society of Anesthesiologist score ≥ 3 (OR 3.08, 95%CI 1.16–8.13) were associated with an increased risk for anastomotic leakage. In a multivariate analysis, male gender (OR 3.62, 95%CI 1.27–10.33) and pulmonary disease (OR 4.37, 95%CI 1.58–12.10) were associated with a greater risk.

Conclusions: The incidence of AL in the present study is similar to that found in comparable series. Respiratory co-morbidity and male sex were found to be the most significant risk factors.

Background: Transesophageal endoscopic ultrasound-guided fine-needle aspiration using a bronchoscope (EUS-B-FNA) allows clinicians to determine mediastinal staging and lung mass evaluation of lesions not accessible by endobronchial ultrasound (EBUS) or where endobronchial ultrasound-guided transbronchial needle aspiration might not be safe.

Objectives: To evaluate the safety, diagnostic accuracy, and feasibility of EUS-B-FNA.

Methods: The study comprised patients who underwent a pulmonologist-performed EUS-B-FNA of mediastinal lymph nodes and parenchymal lung lesions between June 2015 and September 2017 at the Carmel Medical Center, Haifa, Israel.

Results: EUS-B-FNA was performed in 81 patients. The transesophageal procedure was performed for easier accessibility (49.4%) and in high-risk patients (43.3%). The most frequently sampled mediastinal stations were left paratracheal and sub-carinal lymph nodes or masses (38.3% and 56.7%, respectively). There were no complications (e.g., acute respiratory distress, esophageal perforation, or bleeding). An accurate diagnosis was determined in 91.3% of cases.

Conclusions: Pulmonologist-performed EUS-B-FNA is safe and accurate for evaluating mediastinal and parenchymal lung lesions and lymphadenopathy. Diagnostic accuracy is high. EUS-B-FNA may allow access to sites not amenable to other forms of bronchoscopic sampling, or may increase diagnostic accuracy in patients where anatomic position predicts a low diagnostic yield.

Background: The use of oral midazolam as premedication to induce anxiolysis before surgical procedures under local anesthesia is widely accepted in plastic surgery. Rhinoplasty performed under local anesthesia is known to generate high levels of perioperative anxiety, thus the use of appropriate premedication is important. Oral midazolam has been shown to be safe in various procedures. However, the safety of oral midazolam before rhinoplasty has not been evaluated.

Objectives: To evaluate the safety of premedication with oral midazolam prior to rhinoplasty by analyzing the intraoperative blood oxygen saturation levels as predictors of adverse respiratory events.

Methods: We retrospectively reviewed the anesthesia records of 62 patients who underwent rhinoplasty under local anesthesia and received premedication with oral midazolam for anxiolysis between March 2017 and December 2017. The median age of the patients was 25.4 years, and they were all classified as American Society of Anesthesiologists class 1. The patients received 10 mg midazolam hydrochloride orally 1 hour prior to the procedure. Oxygen blood saturation was monitored using a pulse oximeter and recorded every 15 minutes.

Results: All the patients maintained blood oxygen saturation levels above 95% (median peripheral capillary oxygen saturation 99%) on room air, and they did not require supplemental intraoperative oxygen. There were no transient hypoxemic events during and following the procedure.

Conclusions: Our study confirmed the safety of oral midazolam premedication to reduce perioperative anxiety when performing rhinoplasty under local anesthesia.

Background: The frequency of increased high-sensitivity C-reactive protein (hs-CRP) and the time course of evolution of their levels in patients with acute idiopathic pericarditis (AIP) are not well established.

Objective: To assess the time course of evolution of hs-CRP levels and the possible clinical significance of maximal hs-CRP levels in patients with AIP

Methods: We retrospectively reviewed the medical files of 241 patients admitted to the hospital with a diagnosis of AIP between March 2006 and March 2017. Data on demographics, time of symptom onset, laboratory and imaging findings, and outcome were collected.

Results: Data on serum hs-CRP levels were available for 225 patients (age 18–89 years, 181 men). Fever, pleural effusion, and age were independently associated with hs-CRP levels. Major cardiac complications (MCC) (death, cardiac tamponade, cardiogenic shock, large pericardial effusion, ventricular tachycardia, pericardiocentesis, or pericardiectomy) were more common in patients with hs-CRP levels above the median compared to those below (21.2% vs. 4.5%, respectively, P < 0.001). Hs-CRP levels were independently associated with MCC (odds ratio [OR] 1.071, 95% confidence interval [95%CI] 1.016–1.130, P = 0.011). Hs-CRP levels were elevated in 76.0%, 92.3% and 96.0% of the patients tested <6 hours, 7-12 hours, and >12 hours of symptom onset, respectively (P = 0.003). The frequency of elevated hs-CRP among patients tested > 24 hours was 98.1%.

Conclusions: Hs-CRP levels rise rapidly among patients with AIP. Maximal hs-CRP levels are associated with MCC. A normal hs-CRP level is rare among patients tested > 24 hours of symptom onset.

In non-ambulatory patients with cerebral palsy, the presence of scoliosis has a major impact on health and quality of life. The aim of this review is to raise awareness of caregivers from various professions to the extent of the problem, to explain the natural history of neuromuscular scoliosis and its pathophysiology, and to describe up-to-date optional conservative and surgical treatments.

Background: Pneumatic sleeves (PS) are often used during laparoscopic surgery and for prevention of deep vein thrombosis in patients who cannot receive anticoagulation treatment. There is very little information on the hemodynamic changes induced by PS and their effect on brain natriuretic peptide (BNP) in patients with severely reduced left ventricular ejection function (LVEF).

Objectives: To determine the safety and hemodynamic changes induced by PS and their effects on brain natriuretic peptide (BNP).

Methods: This study comprised 14 patients classified as New York Heart Association (NYHA) II–III with severely reduced LVEF (< 40%). We activated the PS using two inflation pressures (50 or 80 mmHg, 7 patients in each group) at two cycles per minute for one hour. We measured echocardiography, hemodynamic parameters, and BNP levels in each patient prior to, during, and after the PS operation.

Results: The baseline LVEF did not change throughout the activation of PS (31 ± 10% vs. 33 ± 9%, P = 0.673). Following PS activation there was no significant difference in systolic or diastolic blood pressure, the pulse measurements, or central venous pressure. BNP levels did not change after PS activation (P = 0.074).

Conclusions: The use of PS, with either low or high inflation pressures, is safe and has no detrimental effects on hemodynamic parameters or BNP levels in patients with severely reduced LVEF following clinical stabilization and optimal medical therapy.

Background: Complete hydatidiform mole and a co-existing normal fetus (CHMCF) is associated with a high complication rate. A possible association with assisted conception might increase the prevalence of CHMCF.

Objectives: To study the potential association between assisted conception and the risks of CHMCF.

Methods: Case series at a single university hospital from 2008 to 2018 are presented and contrasted with data from a comprehensive literature review (1998–2018). Cases were identified from the institutional database that matched the sonographic criteria for CHMCF. A literature review showed comparable cases.

Results: None of the three pregnancies presented in this article resulted in a viable fetus, all were aborted. One of the three patients needed chemotherapy due to gestational trophoblastic neoplasia (GTN). A literature search identified 248 reported cases in which 22 fetuses (9%) reached term, 88/248 (35%) progressed to GTN, and 25/120 (21%) were conceived following assisted conception. From 2008 until 2018 at our medical facility, there were 3144 twin pregnancies of which 1667 (53%) were conceived using assisted conception. In our cohort, there was no statistical trend for assisted conception as an etiological factor for CHMCF.

Conclusions: No association between assisted conception and the risk for CHMCF was established at our hospital, although approximately one-quarter of all reported CHMCF pregnancies are attributed to assisted conception technology. However, these data are not always reported, making it difficult to draw definitive conclusions.

Background: The incidence of Clostridium difficile-associated diarrhea (CDAD) is increasing and is associated with significant morbidity and mortality. Therefore, there is a need to find new tools to determine the severity of the disease.

Objectives: To investigate the prognostic values of inflammatory markers such as mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR), and C-reactive protein (CRP) in patients with CDAD.

Methods: The study comprised of 100 patients diagnosed with CDAD. The study included an additional control group of 69 patients with diarrhea who were negative for C. difficile toxin. The control group was age- and sex-matched and hospitalized at the same time period. NLR and MPV were obtained from complete blood count results. Serum CRP levels were measured by the latex particle enhanced immunoturbidimetric assay. Blood samples for all inflammatory markers were collected at time of diagnosis and prior to initiating the antibiotic therapy. Demographic, clinical, laboratory, and prognostic data were collected from medical records for a period of 90 days from the initial diagnosis of CDAD.

Results: The mean age of the CDAD group was 68.6 ± 21.5 years compared to 65.6 ± 24.5 in the control group (P = 0.29). Our findings show that patients with CDAD had significantly higher NLR, MPV and serum CRP levels compared to the control group (P < 0.001)). Moreover, significantly higher levels were observed when CDAD was fatal (P < 0.001).

Conclusions: Elevated NLR, MPV, and serum CRP levels may serve as biomarkers for prediction of recurrence and mortality in patients with CDAD.
