Objectives: To evaluate the retention of CPR skills and confidence in delivering CPR by preclinical medical students.

Methods: A questionnaire and the Objective Structured Clinical Examination (OSCE) were used to assess confidence and CPR skills among preclinical, second and third-year medical students who had passed a first-aid course during their first year but were not retrained since.

Results: The study group comprised 64 students: 35 were 1 year after training and 29 were 2 years after training. The groups were demographically similar. Preparedness, recollection and confidence in delivering CPR were significantly lower in the 2 years after training group compared to those 1 year after training (P < 0.05). The mean OSCE score was 19.8 ± 5.2 (of 27) lower in those 2 years post- training than those 1 year post-training (17.8 ± 6.35 vs. 21.4 ± 3.4 respectively, P = 0.009). Only 70% passed the OSCE, considerably less in students 2 years post-training than in those 1 year post-training (52% vs. 86%, P < 0.01). Lowest retention was found in checking safety, pulse check, airway opening, rescue breathing and ventilation technique skills. A 1 year interval was chosen by 81% of the participants as the optimal interval for retraining (91% vs. 71% in the 2 years post-training group vs. the 1 year post- training group respectively, P = 0.08).

Conclusions: Confidence and CPR skills of preclinical medical students deteriorate significantly within 1 year post-training, reaching an unacceptable level 2 years post-training. We recommend refresher training at least every year.

 Background: Hemorrhagic radiation cystitis (HRC) is a significant clinical problem that occurs after pelvic radiation therapy and is often refractory.

Objectives: To evaluate the efficacy and safety of hyperbaric oxygen therapy (HBO) for HRC.

Methods: Daily 90 minute sessions of HBO at 2 ATM 100% oxygen were given to 32 HRC patients with American Society of Therapeutic Radiology and Oncology (ASTRO) grades 3-4 hematuria.

Results: The median age was 72.5 (48–88 years). The median time interval between radiation therapy and HBO was 4 years (1–26 years). The patients received a median of 30 HBO sessions (3–53). Hematuria resolved in 27 patients (84%) and persisted in 5. Cystectomy was required in two, and ileal-conduit and bilateral percutaneous nephrostomies were performed in one and two patients, respectively. With a median follow-up of 12 months (5–74 months), the hematuria cleared completely in 16 patients (59%) and mild hematuria requiring no further treatment recurred in 10 others. Another patient with ASTRO grade 4 hematuria needed bladder irrigation and blood transfusions. Complications included eardrum perforation in four patients and transient vertigo and mild hemoptysis in one case each. None of them required HBO discontinuation.

Conclusions: HBO controlled bleeding in 84% of the patients. A durable freedom from significant hematuria was achieved in 96% of the patients. HBO seems to be an effective and safe modality in patients with HRC.

Background: Establishing the etiology of a large pericardial effusion is of crucial importance since it is likely the result of a serious underlying disease. However, there is a paucity of literature on the diagnostic management of patients with large hemorrhagic effusions.

Objectives: To analyze the management of patients with large hemorrhagic pericardial effusion.

Methods: We reviewed seven cases of large hemorrhagic pericardial effusions hospitalized in Soroka University Medical Center in 2010.

Results: All seven patients underwent a comprehensive evaluation followed by pericardiocentesis. Six of the seven cases demonstrated echocardiographic signs of tamponade. Large amounts of hemorrhagic pericardial effusion (> 600 ml) were aspirated from each patient. A pericardial window was performed in two of the seven patients. The causes for the hemorrhagic effusions were malignancy, streptococcal infection, familial Mediterranean fever exacerbation, and idiopathic. Four patients completely recovered. The condition of one patient improved after initiation of chemotherapy for lung cancer, and two patients with progressive malignancies passed away shortly after discharge. Two cases of massive pulmonary embolism were diagnosed which resolved spontaneously without anticoagulation therapy after the effusion was treated.

Conclusions: All cases of pericardial effusion resolved after rapid diagnosis and initiation of specific treatment. Pulmonary embolism in situ may be a complication of large pericardial effusions that does not require anticoagulation treatment after the effusion resolves.
 

Background: Endoscopic techniques have gained popularity in the repair of anterior skull base defects.

Objective: To describe the 10 year experience with endoscopic surgical repair of cerebrospinal fluid (CSF) rhinorrhea in a tertiary medical center.

Methods: The files of all patients who underwent endoscopic transnasal CSF leak repair in our institution between 1996 and 2006 were reviewed.

Results: Twenty-four patients were identified: 16 women and 7 men with a mean age of 48 years and one child aged 9.5 years. The leak was trauma-induced in 17 patients and occurred spontaneously in the other 7. The defect was localized by preoperative computed tomography or CT/cysternography in 86% of cases. A fascia lata graft was the dominant choice for defect closure, and it was combined with a conchal or septal flap, fat, periosteum, or fibrin glue in 15 patients. The success rate was 83% after the first closure attempt, 91% after the second. Two patients required a craniotomy at the third attempt. Mean hospitalization time was 6.7 days. There were two minor complications. Two patients were lost to follow-up; none of the others had a recurrence during 2 years of follow-up.

Conclusions: The endoscopic transnasal technique for the repair of CSF rhinorrhea is associated with a high success rate and low morbidity, and it should be considered for the majority of cases. Repeated attempts may improve success.
 

Background: Ultraviolet B (UVB) rays are required by the skin for the production of vitamin D. The intensity of UVB at the Dead Sea area is the lowest in the world. Low vitamin D levels are often associated with musculoskeletal symptoms.

Objectives: To assess the effectiveness of climatotherapy at the Dead Sea on the production of vitamin D in Norwegian patients suffering from various rheumatic diseases and to investigate possible associations between increased vitamin D serum levels, musculoskeletal symptoms and disease severity.

Methods: Sixty Norwegian patients who came to the Dead Sea area for 21 days of medical rehabilitation were divided into three groups according to their diagnosis: chronic pain syndromes, i.e., low back pain or fibromyalgia (Group 1, n=33); rheumatoid arthritis (Group 2, n=16); and osteoarthritis (Group 3, n=11). Serum 25-hydroxyvitamin D (25-OH-D) levels were determined at arrival and prior to departure. The treatment protocol included daily sun exposure (climatotherapy), bathing in the Dead Sea and mineral spring water (balneotherapy), mud applications and fitness classes.

Results: 25-OH-D serum levels increased significantly from 71.3 ± 26.6 nM at arrival to 89.3 ± 23.2 nM prior to departure (P < 0.001). Adjusted for the initial levels of pain (assessed by a visual analog scale) and disease severity, a direct correlation was observed between increased 25-OH-D serum levels and pain reduction (P = 0.012) and reduction of disease severity (P = 0.02).

Conclusions: Climatotherapy at the Dead Sea induces significant changes in vitamin D. Increased 25-OH-D serum levels are associated with reduced musculoskeletal pain and disease severity.
 

Background: On-site cardiac surgery is not widely available in developing countries despite a high prevalence of coronary artery disease.

Objectives: To analyze the safety, feasibility and cost-effectiveness of transradial percutaneous coronary intervention without on-site cardiac surgery in a community hospital in a developing country.

Methods: Of the 174 patients who underwent PCI[1] for the first time in our center, we analyzed two groups: stable coronary disease and acute myocardial infarction. The primary endpoint was the rate of complications during the first 24 hours after PCI. We also analyzed the length of hospital stay and the rate of hospital readmission in the first week after PCI, and compared costs between the radial and femoral approaches.

Results: The study group comprised 131 patients with stable coronary disease and 43 with acute MI[2]. Among the patients with stable coronary disease 8 (6.1%) had pulse loss, 12 (9.16%) had on-site hematoma, and 3 (2.29%) had bleeding at the site of the puncture. Among the patients with acute MI, 3 (6.98) had pulse loss and 5 (11.63%) had bleeding at the site of the puncture. There were no cases of atriovenous fistula or nerve damage. In the stable coronary disease group, 130 patients (99%) were discharged on the same day (2.4 ± 2 hours). In the acute MI group, the length of stay was 6.6 ± 2.5 days with at least 24 hours in the intensive care unit. There were no hospital readmissions in the first week after the procedure. The total cost, which includes equipment related to the specific approach and recovery room stay, was significantly lower with the radial approach compared to the femoral approach (US$ 500 saving per intervention).

Conclusions: The transradial approach was safe and feasible in a community hospital in a developing country without on-site cardiac surgery backup. The radial artery approach is clearly more cost effective than the femoral approach.

Background: Open repair of the Achilles tendon is still the gold standard for treating rupture. This technique has the disadvantage of a long and problematic operative scar and thickly scarred Achilles tendon. To improve the surgical outcome minimally invasive techniques have been developed.

Objectives: To analyze our results of Achilles tendon repair using the Achillon® device and compare them with published studies.

Methods: We performed surgical repair of the Achilles tendon in 28 patients during a 4 year period (2004–2008): 14 patients were treated with the Achillon device, 12 with the open suture technique and 2 with the percutaneous method. Fourteen patients were available for follow-up: the tendon was repaired in 9 patients with the Achillon device, in 3 patients with open suturing and in 2 patients with the percutaneous technique. Follow-up ranged from 1 to 4 years.

Results: The average score of the AOFAS Ankle-Hindfoot Scale for the group treated with the Achillon device was 95.6 points (range 84–100) and for the group treated with the open method, 90 points (range 84–98). The length of the scar in patients operated with a minimally invasive technique was 3.81 cm (range 1–6 cm) as compared to 9.16 cm (range 8–10.5 cm) with the open suture.

Conclusions: This is the first review on this procedure in Israel. Excellent functional results were achieved with this technique. Our outcomes were similar to those of two other studies.
