Background: Channeling medical resources for coronavirus disease-2019 (COVID-19) management can potentially endanger routine healthcare practices. As a preventive measure, a department of obstetrics and gynecology in Israel constructed a separate, designated complex for its COVID-19-exposed patients.

Objectives: To evaluate the effect of the COVID-19 pandemic infection control measures on obstetric care in the obstetrical emergency department and delivery unit.

Methods: The authors collected data retrospectively from February 2020 to March 2020 and compared it to data of a parallel period in 2019.

Results: From 1 February 2020 to 28 March 2020, 3897 women were referred to the emergency department (ED), compared to 4067 the previous year. Mean duration of treatment until decision and referral indications did not differ between 2020 and 2019 (207 vs. 220 minutes, P = 0.26; urgent referrals 58.8% vs. 59.2%, P = 0.83). A per-week comparison showed a significant reduction in ED referrals only in the last week of the period (337 [2020] vs. 515 [2019], P < 0.001). The proportion of women admitted to the delivery unit in active labor was significantly higher in the last three weeks (39.1% vs. 28.2%, P = 0.005). During February and March 2020, 1666 women delivered, compared to 1654 during February and March 2019. The proportion of types and modes of delivery did not differ. In a per-week comparison, the number of deliveries did not differ (mean 208 vs. 206, P = 0.88).

Conclusions: With timely preparation and proper management, negative impact of COVID-19 can be reduced in obstetrical emergency departments.

Background: Pancreatic injuries during nephrectomy are rare, despite the relatively close anatomic relation between the kidneys and the pancreas. The data regarding the incidence and outcome of pancreatic injuries are scarce.

Objectives: To assess the frequency and the clinical significance of pancreatic injuries during nephrectomy.

Methods: A retrospective analysis was conducted of all patients who underwent nephrectomy over a period of 30 years (1987–2016) in a large tertiary medical center. Demographic, clinical, and surgical data were collected and analyzed.

Results: A total of 1674 patients underwent nephrectomy during the study period. Of those, 553 (33%) and 294 patients (17.5%) underwent left nephrectomy and radical left nephrectomy, respectively. Among those, four patients (0.2% of the total group, 0.7% of the left nephrectomy group, and 1.36% of the radical left nephrectomy) experienced iatrogenic injuries to the pancreas. None of the injuries were recognized intraoperatively. All patients were treated with drains in an attempt to control the pancreatic leak and one patient required additional surgical interventions. Average length of stay was 65 days (range 15–190 days). Mean follow-up was 23.3 months (range 7.7–115 months).

Conclusions: Pancreatic injuries during nephrectomy are rare and carry a significant risk for postoperative morbidity.

Background: Untreated dental caries or even dental manipulations, such as a tooth extraction, might cause direct spread of an odontogenic infection and consequently the development of life-threatening conditions such as deep neck infections (DNI). The most common source of DNI is of odontogenic origin (38.8–49%). Abscess formation or cellulitis can lead to life-threatening complications, despite new diagnostic imaging technology and widespread availability of antibiotics. 

Objectives: To demonstrate the dangers of DNI, which can create life-threatening situations.

Methods: Five cases of DNI of odontogenic origin, which were referred to the oral and maxillofacial surgery unit, are presented. 

Results: Clinical manifestations included trismus, dysphagia, dysphonia, dyspnea, and infection symptoms. In all cases, computed tomography confirmed diagnosis and extent of abscess. Complications included mediastinitis, respiratory distress, osteomyelitis of the jaws, and in rare cases the mandibular condyle. Treatment included securing the airway, immediate surgical drainage, removal of the infection source, and antibiotic therapy. All patients were discharged in stable and improved condition.

Conclusions: DNI treatment on an emergency basis requires proper diagnosis and effective management. To confirm diagnosis and prevent serious complications, it is essential for physicians to recognize the spaces of the head and neck that are likely to be affected by DNI. 

 

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: Surgery is a core activity in hospitals. Operating rooms have some of the most important and vital functions in medical centers. The operating rooms and their staff are a valuable infrastructure resource and their availability and preparedness affect human life and quality of care.

Objectives: To prepare operational suggestions for improving operating room utilization by mapping current working processes in the operating rooms of a large private medical center.

Methods: Data on 23,585 surgeries performed at our medical center between August 2016 and March 2017 were analyzed by various parameters including utilization, capacity, working hours, and surgery delays.

Results: Average operating room utilization was 79%, while 21% was considered lost operating room time. The two major factors that influenced the lost operating room time were the time intervals between planned usage blocks and the partial utilization of operating room time. We calculated that each percent of utilized operating room time translates into 440 surgeries annually, resulting in a potential annual increase in income.

Conclusions: Increasing operating room utilization would result in an improvement of operating room availability and an increased number of procedures. Our analysis shows that operating room utilization in the private healthcare system is efficient compared to the public healthcare system in Israel. Therefore the private healthcare system should be treated as a contributing factor to help lower surgery waiting times and release bottlenecks, rather than being perceived as contributing to inequality.

Background: Selective management of stable patients with anterior abdomen stab wounds (AASWs) has become a gold standard management approach throughout the world. Evidenced-based options for supporting selective management include clinical follow-up, local wound exploration with or without diagnostic peritoneal lavage, diagnostic laparoscopy, and abdominal computerized tomography. The presence of multiple AASWs might signify a more aggressive attack and limit the safety of a selective management approach.

Objectives: To evaluate whether multiple AASWs are associated with an increased risk of intra-abdominal injury requiring emergency surgery.

Methods: We retrospectively reviewed all AASW patients admitted to Assaf Harofeh Medical Center, Zerifin, Israel, and Hillel Yaffe Medical Center in Hadera, Israel, from 2007 to 2015. Patients were divided into two groups based on the number of stab wounds: single or multiple. Data were coded for demographics, severity of injury, presence of intra-abdominal injury, laparotomy rate, length of hospital stay (LOS), length of stay in the intensive care unit (LICU), and survival.

Results: The study included 169 patients. Of these, 143 patients had a single AASW and 26 had multiple AASWs. There were no differences between the groups regarding demographics, severity of injury, intra-abdominal penetration, specific organ injury, LOS, or LICU. There was no difference in the percentage of patients requiring laparotomy. The overall mortality was 2.36% (4/169). There was no significant difference in the mortality rate between the groups (P = 0.11).

Conclusions: The presence of multiple AASWs is not a risk factor for increased frequency and severity of intra-abdominal injury.

Background: The currently accepted treatment for idiopathic sudden sensorineural hearing loss (ISSHL) is systemic steroids as first-line and intratympanic steroids as salvage therapy. Intratympanic (IT) treatment is applied worldwide in many different ways with no universally accepted protocol.

Objectives: To present the current disparity in ISSHL management and to discuss the necessity for establishing a common national protocol.

Methods: In 2014 we conducted a national survey by sending questionnaires on ISSHL management to otologists in every otolaryngology department in the country.

Results: The majority of otolaryngology departments (56%) admit patients with sudden sensorineural hearing. Almost two-thirds (61%) of departments recommend supplementary initial treatment in addition to systemic steroids. None of the medical centers offer intratympanic steroid treatment as primary therapy, but 94% offer this treatment as a salvage therapy. Fewer than half the medical centers (44%) consider the maximal period for intratympanic therapy to be 4 weeks since hearing loss appears. Almost half (48%) the departments use intratympanic steroids once every 5–7 days, usually in an ambulatory setting. Almost half (44%) the medical centers tend to use not more than four courses of IT steroids. In 44% of departments an audiogram is performed at the beginning and at the end of the intratympanic course.

Conclusions: Our results demonstrate a variability among Israeli medical centers in many aspects of intratympanic treatment. We believe this reinforces the need for a comparative international study in order to establish a standard protocol.

Background: Adjuvant radiotherapy for breast cancer reduces local recurrence and improves survival. In patients with left sided breast cancer, anterior heart position or medial tumor location may cause inadequate breast coverage due to heart shielding. Respiration gating using the Real-time Position Management (RPM) system enables pushing the heart away from the tangential fields during inspiration, thus optimizing the treatment plan.

Objectives: To compare breathing inspiration gating (IG) techniques with free breathing (FB), focusing on breast coverage.

Methods: The study comprised 49 consecutive patients with left sided breast cancer who underwent lumpectomy and adjuvant radiation. RPM was chosen due to insufficient breast coverage caused by an anterior heart position or medial lumpectomy cavity. FB and IG computed tomography simulations were generated for each patient. Breast (PTVbreast) and lumpectomy cavity (CTVlump) were defined as the target areas. Optimized treatment plans were created for each scan. A dosimetric comparison was made for breast coverage and heart and lungs doses.

Results: PTVbreast V95% and mean dose (Dmean) were higher with IG vs. FB (82.36% vs. 78.88%, P = 0.002; 95.73% vs. 93.63%, P < 0.001, respectively). CTVlump V95% and Dmean were higher with IG (98.87% vs. 88.92%, P = 0.001; 99.14% vs. 96.73%, P = 0.003, respectively). The cardiac dose was lower with IG. The IG left lung Dmean was higher. No statistical difference was found for left lung V20.

Conclusions: In patients with suboptimal treatment plans due to anterior heart position or medial lumpectomy cavity, RPM IG enabled better breast/tumor bed coverage and reduced cardiac doses.

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.
