Background: A limited program for kidney donation from uncontrolled donation after cardiocirculatory determination of death (uDCDD) was implemented at four hospitals in Israel in close cooperation with Magen David Adom (MDA), the national emergency medical service.

Objectives: To assess the outcome of transplantations performed between January 2017 and June 2022.

Methods: Donor data included age, sex, and cause of death. Recipient data included age, sex, and yearly serum creatinine levels. A retrospective study of out-of-hospital cardiac arrest cases treated by MDA during 2021 were analyzed to assess their compatibility as potential uDCDD donors.

Results: In total, 49 potential donors were referred to hospitals by MDA. Consent was obtained in 40 cases (83%), organ retrieval was performed in 28 cases, and 40 kidneys were transplanted from 21 donors (75% retrieval rate). At 1-year follow-up, 36 recipients had a functioning graft (4 returned to dialysis) and mean serum creatinine 1.59 ± 0.92 mg% (90% graft survival). Outcome after transplantation showed serum creatinine levels (mg%) at 2 years 1.41 ± 0.83, n=26; 3 years 1.48 ± 0.99, n=16; 4 years 1.07 ± 1.06, n=7; and 5 years 1.12 ± 0.31, n=5. One patient died of multiple myeloma at 3 years. The MDA audit revealed an unutilized pool of 125 potential cases, 90 of whom were transported to hospitals and 35 were declared dead at the scene.

Conclusions: Transplant outcomes were encouraging, suggesting that more intensive implementation of the program may increase the number of kidneys transplanted, thus shortening recipient waiting lists.

Pancreaticopleural fistula (PPF) is a rare complication of pancreatitis and usually constitutes a diagnostic challenge. There are many causes for recurrent and chronic pancreatitis, with the main etiology being alcohol and choledocholithiasis [1]. However, the association between pancreatic divisum (PD), a common congenital anomaly of the pancreas that is rarely symptomatic, and complications of pancreatitis is still not firmly established [2]. Furthermore, the optimal management of PPF is still uncertain due to its rarity [3]. We describe a rare case of a 45-year-old woman with recurrent pancreatitis that presented with a PPF on the background of PD, successfully managed with conservative treatment. The purpose of this report is to highlight the rare association between PPF and PD together with the excellent response to conservative therapy.

Background: Several approaches are used to access the hip joint; most common are the direct lateral and posterior. Little consensus exists on which to use when treating hip fractures.

Objectives: To compare short-term complications, postoperative ambulation, and patient-reported outcome measures (PROMS) of direct lateral vs. posterior approaches in hemiarthroplasty for acute hip fractures.

Methods: We conducted a retrospective clinical trial with 260 patients who underwent bipolar hemiarthroplasty in the direct lateral or posterior approach (166 and 94, respectively) between January 2017 and December 2018. The clinical data included short-term complications: prosthetic dislocation, periprosthetic fractures, and infection. Postoperative ambulation was collected 6 weeks postoperatively; PROMS were collected for 173 patients at 2 years follow-up.

Results: There were six dislocations overall, average time to dislocation was 22 days postoperative (range 4–34). Five dislocations were after the posterior approach (5.3%) and one after direct lateral (0.6%) (P = 0.01). At 6 weeks follow-up, inability to walk was found in 16.9% of the direct lateral group and 6.4% of the posterior approach group (P = 0.02). In the posterior approach group, 76% could walk more than 20 meters; only half of the direct lateral group could (P = 0.0002). At 2 years follow-up, PROMS did not show a statistically significant difference between the groups.

Conclusions: Posterior approach for hemiarthroplasty following femoral neck fractures allows superior ambulation to the direct lateral approach only for the short-term. However, no long-term clinical advantage was found. This short-term benefit does not justify the increased dislocation rate in the posterior approach.

Background: Medical organizations worldwide aim for equity and diversity in the medical profession to improve care quality. Data on whether the caregiver gender affects outcomes in the prehospital setting are essential but scarce compared to available in-hospital studies.

Objective: To analyze the rates of missed injuries in the prehospital setting and determine whether these rates were associated with the gender of the on-field physician or paramedic.

Methods: A retrospective record review was conducted, which included trauma records documented in two trauma registries, the prehospital Israel Defense Forces-Trauma Registry (IDF-TR), and the in-hospital Israeli National Trauma Registry (INTR). Missed injuries were defined as injuries documented in the INTR but not in the IDF-TR. A multivariable regression analysis was performed to assess the association between provider’s gender and missed injuries.

Results: Of 490 casualties, 369 (75.3%) were treated by teams that included only male paramedics or physicians. In 386 (78.8%) cases, a physician was a part of the prehospital team. In all, 94 (19.2%) casualties sustained injuries that were missed by the prehospital medical team. Missed injuries were not associated with the gender of the paramedic or physician (odds ratio 1.242, 95% confidence interval 0.69–2.193).

Conclusions: No association was found between the gender of the medical provider in the prehospital setting and the rate of missed injuries. These results should encourage prehospital emergency medical systems to aim for a balanced and diverse caregiver population.

Background: Surgery for hip fractures within 48 hours of admission is considered standard. During the lockdown period due to the coronavirus disease-2019 (COVID-19) epidemic, our medical staff was reduced.

Objectives: To compare the demographics, treatment pathways, and outcomes of patients with hip fractures during the COVID-19 epidemic and lockdown with the standard at routine times.

Methods: A retrospective study was conducted of all patients who were treated surgically for hip fracture in a tertiary center during the COVID-19 lockdown period between 01 March and 01 June 2020 and the equivalent period in 2019. Demographic characteristics, time to surgery, surgery type, hospitalization time, discharge destination, postoperative complications, and 30- and 90-day mortality rates were collected for all patients.

Results: During the COVID-19 period, 105 patients were operated due to hip fractures compared to 136 in the equivalent period with no statistical difference in demographics. The rate of surgeries within 48 hours of admission was significantly higher in the COVID-19 period (92% vs. 76%, respectively; P = 0.0006). Mean hospitalization time was significantly shorter (10 vs. 12 days, P = 0.037) with diversion of patient discharge destinations from institutional to home rehabilitation (P < 0.001). There was a significant correlation between the COVID-19 period and lower 90-day mortality rates (P = 0.034). No statistically significant differences in postoperative complications or 30-day mortality rates were noted.

Conclusions: During the COVID-19 epidemic, despite the limited staff and the lack of therapeutic sequence, there was no impairment in the quality of treatment and a decrease in 90-day mortality was noted.

Background: Consent rates for organ donation remain one of the most important factors determining the number of organs available for transplantation. Trauma casualties constitute a substantial part of the deceased organ donor pool and have unique characteristics that distinguish them from the general donor population. However, this group has not been extensively studied.

Objectives: To identify donor factors associated with positive familial consent for solid organ donation among trauma casualties.

Methods: This retrospective study included all trauma casualties who were admitted to the Rabin Medical Center, Beilinson hospital, during the period from January 2008 to December 2017, who were potential organ donors. Data collected included demographic features, the nature of the injury, surgical interventions, and which organs were donated. Data was collected from the Rabin Medical Center Trauma Registry.

Results: During the study period 24,504 trauma patients were admitted and 556 died over their hospital course. Of these 76 were potential donors, of whom 32 became actual donors and donated their organs. Two factors showed a statistically significant correlation to donation, namely female gender (P = 0.018) and Jewish religion of the deceased (P = 0.032).

Conclusions: Only a small group of in hospital trauma deaths were potential solid organ donors (13.7%) and less than half of these became actual donors. Consent rates were higher when the deceased was female or Jewish

Background: Dietary modifications and patient-tailored medical management are significant in controlling renal stone disease. Nevertheless, the literature regarding effectiveness is sparse.

Objectives: To explore the impact of dietary modifications and medical management on 24-hour urinary metabolic profiles (UMP) and renal stone status in recurrent kidney stone formers.

Methods: We reviewed our prospective registry database of patients treated for nephrolithiasis. Data included age, sex, 24-hour UMP, and stone burden before treatment. Under individual treatment, patients were followed at 6–8 month intervals with repeat 24-hour UMP and radiographic images. Nephrolithiasis-related events (e.g., surgery, renal colic) were also recorded. We included patients with established long-term follow-up prior to the initiation of designated treatment, comparing individual nephrolithiasis status before and after treatment initiation.

Results: Inclusion criteria were met by 44 patients. Median age at treatment start was 60.5 (50.2–70.2) years. Male:Female ratio was 3.9:1. Median follow-up was 10 (6–25) years and 5 (3–6) years before and after initiation of medical and dietary treatment, respectively. Metabolic abnormalities detected included: hypocitraturia (95.5%), low urine volume (56.8%), hypercalciuria (45.5%), hyperoxaluria (40.9%), and hyperuricosuria (13.6%). Repeat 24-hour UMP under appropriate diet and medical treatment revealed a progressive increase in citrate levels compared to baseline and significantly decreased calcium levels (P = 0.001 and 0.03, respectively). A significant decrease was observed in stone burden (P = 0.001) and overall nephrolithiasis-related events.

Conclusions: Dietary modifications and medical management significantly aid in correcting urinary metabolic abnormalities. Consequently, reduced nehprolithiasis-related events and better stone burden control is expected.

Background: The effect of weight reduction following bariatric surgery is already well known.

Objectives: To investigate the effects of abdominoplasty on metabolic markers indicative of weight loss.

Methods: The authors prospectively enrolled consecutive obese patients after laparoscopic sleeve gastrectomy. They were candidates for post-bariatric surgery abdominoplasty. The authors measured metabolic markers one day prior to surgery, 24 hours after, and 3 months following surgery. They recorded medical and demographic parameters.

Results: Sixteen patients were recruited for participation in the study. Mean age was 47 years and 88% of the patients were female. Bariatric surgery achieved a mean decline in body mass index of 13.8 kg/m². All patients underwent abdominoplasty. Leptin and insulin levels were slightly increased at 3 months postoperative. No significant changes were observed in glucose, hemoglobin, or triglycerides throughout the study.

Conclusions: In a cohort of obese patients undergoing laparoscopic sleeve gastrectomy followed by abdominoplasty, no significant changes were noted in a patient’s metabolic profiles. The results suggest that abdominoplasty has no effect on the metabolic markers tested in contrast to other reports; however, the cosmetic, behavioral, and psychological advantages of abdominoplasty are well established.

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: The identification of the etiology of a pleural effusion can be difficult. Measurement of serum B-type natriuretic peptide (BNP) levels is helpful in the diagnosis of congestive heart failure (CHF) as a cause of respiratory failure, but pleural fluid BNP measurement is still not part of the workup for pleural effusion.

Objectives: To identify the correlation between pleural fluid BNP levels and clinical diagnosis.

Methods: In this cross-sectional study, data from 107 patients admitted to the department of internal medicine between November 2009 and January 2015 were obtained from medical records. Patients underwent a diagnostic thoracocentesis as part of their evaluation. They were grouped according to final diagnosis at discharge and clinical judgment of the attending physician.

Results: Serum BNP levels were significantly higher in the CHF patients compared to patients with non-cardiac causes of pleural effusion (1519.2 and 314.1 respectively, P < 0.0001). Mean pleural fluid BNP was also significantly higher in the CHF patients (1063.2 vs. 208.3, P < 0.0001). Optional cutoff points to distinguish between cardiac and non-cardiac etiology of pleural effusion were 273.4 pg/ml (sensitivity 83.3%, specificity 72.3%, accuracy 76.7%) or 400 pg/ml (sensitivity 78.6%, specificity 86.2%, accuracy 83.0%). A strong correlation was found between serum BNP and pleural fluid BNP levels.

Conclusions: High levels of serum BNP in patients presenting with pleural effusion suggest CHF. In cases with doubt regarding the etiology of pleural effusion, high levels of pleural fluid BNP can support the diagnosis, but are not superior to serum BNP levels.

Background: Male infertility is solely responsible for approximately 20% of all infertility in couples. Various factors have been proposed as having a negative effect on sperm quality; however, the reasons for the global decline in sperm parameters during the last few decades are still controversial. 

Objectives: To investigate the fluctuations of semen parameters (sperm concentration, motility, and morphology) in three sperm quality groups and to examine the trends of those parameters in the same men over time. 

Results: Our data showed deterioration in all semen parameters assessed in the group of men originally considered as having normal semen values according to the 2010 criteria of the World Health Organization. In contrast, we found significant improvement over time in all semen parameters in the group of men with severe oligo-terato-asthenozoospermia. 

Conclusions: Our results suggest that, although there were changes in sperm quality over time in the groups assessed, the clinical significance is negligible and does not necessarily justify a change in the therapeutic approach to infertility or sperm cryopreservation. 

 

Background: Accurate pulse oximetry reading at hospital admission is of utmost importance, mainly for patients presenting with hypoxemia. Nevertheless, there is no accepted or evidence-based protocol for such structured measuring.

Objectives: To devise and assess a structured protocol intended to increase the accuracy of pulse oximetry measurement at hospital admission.

Methods: The authors performed a prospective comparison of protocol-based pulse-oximetry measurement with non-protocol based readings in consecutive patients at hospital admission. They also calculated the relative percentage of improvement for each patient (before and after protocol implementation) as a fraction of the change in peripheral capillary oxygen saturation (SpO₂) from 100%.

Results: A total of 460 patients were recruited during a 6 month period. Implementation of a structured measurement protocol significantly changed saturation values. The SpO₂ values of 24.7% of all study participants increased after protocol implementation (ranging from 1% to 21% increase in SpO₂ values). Among hypoxemic patients (initial SpO₂ < 90%), protocol implementation had a greater impact on final SpO₂ measurements, increasing their median SpO₂ readings by 4% (3–8% interquartile range; P < 0.05). Among this study population, 50% of the cohort improved by 17% of their overall potential and 25% improved by 50% of their overall improvement potential. As for patients presenting with hypoxemia, the median improvement was 31% of their overall SpO₂ potential.

Conclusions: Structured, protocol based pulse-oximetry may improve measurement accuracy and reliability. The authors suggest that implementation of such protocols may improve the management of hypoxemic patients.

The progression from standard celluloid films to digitalized technology led to the development of new software programs to fulfill the needs of preoperative planning. We describe here preoperative digitalized programs and the variety of conditions for which those programs can be used to facilitate preparation for surgery. A PubMed search using the keywords “digitalized software programs”, “preoperative planning” and “total joint arthroplasty” was performed for all studies regarding preoperative planning of orthopedic procedures that were published from 1989 to 2014 in English. Digitalized software programs are enabled to import and export all picture archiving communication system (PACS) files (i.e., X-rays, computerized tomograms, magnetic resonance images) from either the local working station or from any remote PACS. Two-dimension (2D) and 3D CT scans were found to be reliable tools with a high preoperative predicting accuracy for implants.  The short learning curve, user-friendly features, accurate prediction of implant size, decreased implant stocks and low-cost maintenance makes digitalized software programs an attractive tool in preoperative planning of total joint replacement, fracture fixation, limb deformity repair and pediatric skeletal disorders.
