Background: C-reactive protein (CRP) is often used to distinguish bacterial from viral infections. However, the CRP level does have implications, which depend on the clinical scenario and are still under research.

Objectives: To evaluate the distribution of CRP levels in children with primary herpetic gingivostomatitis.

Methods: The electronic database of a tertiary pediatric medical center was searched for all inpatients with a diagnosis of primary herpetic gingivostomatitis without bacterial co-infection. Background and clinical information was collected and CRP levels were analyzed.

Results: The study group consisted of 66 patients aged 8 months to 7.1 years who met the study criteria. The average CRP was 7.4 mg/dl (normal < 0.5 mg/dl). More than a third of the patients had a level higher than 7 mg/dl.

Conclusions: High values of CRP are prevalent in patients with primary herpetic gingivostomatitis, similar to adenoviral infections and some bacterial infections. 

Objectives: To characterize common obstetric anesthesia practices after cesarean deliveries in Israel in order to standardize postoperative pain relief protocols.

Methods: A questionnaire was completed during an interview with every obstetric anesthesia unit in all 25 delivery wards in Israel. Data were gathered on intraoperative anesthesia and analgesia protocols as well as postoperative pain relief protocols. A sub-analysis compared units whose director completed a formal obstetric anesthesia training program with those whose directors did not.

Results: Neuraxial morphine was used routinely in 12% of hospitals. No unit providing intrathecal morphine complied with American Society of Anesthesiologists guidelines for respiratory monitoring after use of neuraxial opioids. Additionally, non-steroidal anti-inflammatory drugs (NSAIDs) were used routinely in only half the wards, while patient-controlled analgesia was used infrequently. Postoperative verbal analog scores were not recorded routinely in 71% of units on postoperative day 1. The unit director's training significantly influenced the unit protocols.

Conclusions: Intrathecal morphine, the gold standard of care in cesarean deliveries, is rarely used, mainly due to shortage of staff and lack of formal obstetric anesthesia training. In addition, NSAIDs are also underused. There is a need for more formal training for obstetric anesthesiologists in Israel.

Objectives: To determine if low plasma vitamin D level is a risk factor for MAEs in statin users.

Methods: Plasma levels of 25(OH) vitamin D were measured as part of the routine evaluation of unselected statin-treated patients attending the coronary and lipid clinics at our hospital during the period 2007–2010. Medical data on muscle complaints and statin use were retrieved from the medical files. Creatine kinase (CK) levels were derived from the hospital laboratory database.

Results: The sample included 272 patients (141 men) aged 33–89 years. Mean vitamin D level was 48.04 nmol/L. Levels were higher in men (51.0 ± 20.5 vs. 44.7 ± 18.9 nmol/L, P = 0.001) and were unaffected by age. MAEs were observed in 106 patients (39%): myalgia in 95 (35%) and CK elevation in 20 (7%); 11 patients (4%) had both. There was no difference in plasma vitamin D levels between patients with and without myalgia (46.3 ± 17.7 vs. 48.9 ± 21.0 nmol/L, P = 0.31), with and without CK elevation (50.2 ± 14.6 vs. 47.8 ± 20.3 nmol/L, P = 0.60), or with or without any MAE (50.4 ± 15.0 vs. 47.8 ± 10.2 nmol/L, P = 0.27). These findings were consistent when analyzed by patient gender and presence/absence of coronary artery disease, and when using a lower vitamin D cutoff (< 25 nmol/L).

Conclusions: There is apparently no relationship between plasma vitamin D level and risk of MAEs in statin users.

Objectives: To assess the results of endovascular revascularization for lower extremity ischemia in dialysis patients.

Methods: We conducted a retrospective review of all dialysis patients who underwent endovascular treatment for critical limb ischemia (CLI) in our institution between 2007 and 2011. Data collected included comorbidities, clinical presentation, anatomic distribution of vascular lesions, amputation and survival rates.

Results: We identified 50 limbs (41 patients). Indications included: gangrene in 22%, non-healing wounds in 45%, rest pain in 31%, and debilitating claudication in 4%. Mean follow-up was 12 months (1–51 months). Nineteen patients required amputations. Freedom from amputation at 5 years was 40%. Factors associated with amputation included non-healing wounds or gangrene (68% and 36% respectively) and diabetes (P < 0.05). The survival rate was 80% after 5 years.

Conclusions:  Despite improvement in endovascular techniques for lower extremity revascularization, the incidence of limb salvage among dialysis patients remains poor, resulting in a high rate of major amputations. 

Objectives: To determine the effect of vitamin K on hip fracture patients treated with warfarin.

Methods: We retrospectively examined the management of 21 patients with hip fractures who were being treated with warfarin at the time of admission. Vitamin K was given to 11 of the 21 patients. A third group, which served as a control, consisting of 35 hip fracture patients who were not being treated with anticoagulants was also evaluated.

Results: Patients who received vitamin K took fewer days to reach target international normalized ratio (INR) (1.73 ± 0.90 vs. 4.30 ± 1.89, P < 0.001) and had less preoperative time (2.64 ± 1.12 vs. 5.10 ± 2.42 days, P < 0.008) when compared with patients who did not receive vitamin K. In addition, these patients had statistically significantly shorter hospitalization stays (9.4 ± 1.9 and 13.2 ± 4.9 days, one-sided P < 0.06). There was no difference in the amount of blood found in the wound drains (111.8 ± 68.5 vs. 103.0 ± 69.4 ml) or the number of blood units administered (1.45 ± 1.29 vs. 2.00 ± 2.75 units).

Conclusions: Treatment with vitamin K for hip fracture patients who receive warfarin shortens preoperative time, reduces the length of hospitalization and probably reduces morbidity and mortality.

Objectives: To evaluate glycemic control, prevalence of diabetic ketoacidosis (DKA) at presentation, diabetic complications rate, and associated autoimmune diseases in a pediatric T1DM patient population in the Negev area.

Methods: Clinical and demographic details of 168 T1DM patients were evaluated, including HbA1C levels, long-term complications, related autoimmune diseases, and insulin pump usage. The data were analyzed and the Jewish and Bedouin patient groups compared.

Results: Only 13.1% of the patients had reached the HbA1C levels recommended by the current guidelines at the first and second year follow-up visits, and 9.5% and 7.1% at the third and fourth year visits, respectively. A significant difference in HbA1c levels between Jewish and Bedouin patients was found (P = 0.045 at the first year follow-up, P ≤ 0.01 thereafter). Significant difference was found between the Jewish and the Bedouin groups regarding presentation with DKA, 33% and 56% of the patients respectively (P = 0.01).

Conclusions: Existent glycemic control in daily practice is far from the guideline goals. Bedouin ethnicity was associated with less favorable diabetes control, emphasizing the need for better awareness of T1DM and its treatment options in this population. More resources should be directed to address T1DM in the general population, especially among the Bedouin.

Objectives: To examine prospectively the feasibility of vessel sealing in tracheostomy.

Methods: A vessel-sealing device was used in 24 consecutive patients undergoing tracheostomy. There were no exclusion criteria for enrolling the patients. No other hemostatic technique was used for dividing the isthmus.

Results: There were no bleeding events throughout the postoperative period. The operating time savingwas 5–10 minutes.

Conclusions: Use of the vessel sealer was found to be straightforward, efficacious, rapid and safe. 

Objectives: To review our use of ECMO over a 10 year period.

Methods: All children supported with ECMO from 2000 to 2010 were reviewed. Most of these children suffered from cardiac anomalies. The patients were analyzed by age, weight, procedure, RACHS-1 when appropriate, length of support, and outcome.

Results: Sixty-two children were supported with ECMO; their median age was 3 months (range 0–216 months) and median weight 4.3 kg (range 1.9–51 kg). Thirty-four patients (52.3%) needed additional hemofiltration or dialysis due to renal failure. The children requiring ECMO support represented a wide spectrum of cardiac lesions; the most common procedure was arterial switch operation 27.4% (n=17). ECMO was required mainly for failure to separate from the heart-lung machine (n=55). The median duration of ECMO support was 4 days (range 1–14 days); 29 (46.7%) patients were weaned successfully from ECMO during this time period, and 5 of them died during hospitalization, yielding an overall hospital survival rate of 38.7%.

Conclusions: ECMO support has significant survival benefit for patients with post-cardiotomy heart failure. Its early deployment should be considered in cardiopulmonary resuscitation.

Background: Vascular insufficiency is considered to play an important role in the pathogenesis of normal-tension glaucoma (NTG). Autoregulation of blood flow in the eye has been shown to be impaired in NTG, resulting in the inability to compensate for changes in intraocular pressure or blood pressure in order to maintain adequate perfusion. Objectives: To evaluate the occurrence of combined bradycardia-hypotension during 24 hour monitoring of blood pressure and heart rate in patients with NTG.

Methods: Eleven NTG patients participated in the study. All had episodic symptoms of dizziness or lightheadedness, but were confirmed as not having a diagnosis of orthostatic hypotension. Twenty-four hour monitoring was performed with systemic blood pressure and heart rate automatically measured every 20 minutes during daytime and every hour during the night. The cardiac diastolic and systolic double products (dDP and sDP) at each reading were calculated by multiplying the heart rate by the respective blood pressure. dDP < 3600 and sDP < 5400 (corresponding to a heart rate of 60 beats/min and a blood pressure of 60 and 90 mmHg, respectively) were considered abnormally low, and dDP < 2500 and sDP < 4000 (corresponding to a heart rate 50 beats/min and a blood pressure of 50 and 80 mmHg, respectively) were considered severely abnormal.

Results: dDP was abnormally low in all 11 NTG patients on at least one occasion, the majority occurring during the night-time hours, while abnormally low sDP was present in 8 of the 11 patients. The mean cumulative duration of low dDP readings was 4.2 ± 3.2 hours. Severely low dDP readings were observed in six patients.

Conclusions: Abnormally low dDP was recorded in all NTG patients, lasting more than an hour in the majority of cases. Abnormally decreased dDP may represent a state of cardiovascular autonomic dysregulation, resulting in low ocular perfusion in certain NTG patients.
