Background: Accurate diagnosis of community acquired pneumonia (CAP) is crucial to its proper management and to combating antibiotic resistance. Levels of C-reactive protein (CRP) have been shown to distinguish pneumonia from other pathological conditions and can be used to control the severity of infection during admission.

Objective: To investigate an association between consecutive measurements of CRP and the severity of CAP in hospitalized patients.

Methods: A total of 500 patients with CAP were admitted to the hospital. Traditional markers of inflammation including CRP, leukocyte count, body temperature, were measured on the first, second, and fifth days of hospitalization. Correlations between these measures and the length of the hospital stay were calculated.

Results: Mean levels of CRP, body temperature, and leukocyte count were significantly lower on the second day after hospital admission and even lower on the fifth day. A positive correlation of medium strength was found between the level of CRP on the second day of hospitalization and the length of hospital stay (P < 0.001, r_s = 0.447), and a negative correlation was noted between the decrease in CRP level from the first to second day and the length of hospital stay.

Conclusions: CRP levels correlated with body temperature and leukocyte count, traditional markers of inflammation. A greater decrease in CRP level between the first and second day of hospitalization was associated with shorter hospital stay and rapid improvement. These findings support the use of CRP as a marker for the severity and complication of CAP.

Background: Wandering spleen is a rare entity that may pose a surgical emergency following torsion of the splenic vessels, mainly because of a delayed diagnosis. Complications after surgery for wandering spleen may necessitate emergency treatment.

Objectives: To describe the clinical course and treatment for children who underwent emergency surgeries for wandering spleen at a tertiary pediatric medical center over a 21 year period and to indicate the pitfalls in diagnosis and treatment as reflected by our experience and in the literature.

Methods: The database of a tertiary pediatric medical center was searched retrospectively for all children who underwent emergency treatment for wandering spleen between 1996 and 2017. Data were collected from the medical files. The relevant literature was reviewed.

Results: Of ten patients who underwent surgery for wandering spleen during the study period, five underwent seven emergency surgeries. One patient underwent surgery immediately at initial presentation. In the other four, surgical treatment was delayed either due to misdiagnosis or for repeated imaging studies to confirm the diagnosis. Emergency laparotomy revealed an ischemic spleen in all patients; splenectomy was performed in two and the spleen was preserved in three. Four of the seven emergency operations were performed as the primary surgery and three were performed to treat complications.

Conclusions: Wandering spleen should ideally be treated on an elective or semi-elective basis. Surgical delays could be partially minimized by a high index of suspicion at diagnosis and by eliminating unnecessary and time-consuming repeated imaging studies.

Background: About half of all patients with heart failure are diagnosed with heart failure preserved ejection fraction (HFpEF). Until now, studies have failed to show that medical treatment improves the prognosis of patients with HFpEF.

Objectives: To evaluate changes in exercise capacity of patients with HFpEF compared to those with heart failure with reduced ejection fraction (HFrEF) following an exercise training program.

Methods: Patient data was retrieved from a multi-center registry of patients with heart failure who participated in a cardiac rehabilitation program. Patients underwent exercise testing and an echocardiogram prior to entering the program and were retested6  months later.

Results: Of 216 heart failure patients enrolled in the program, 170 were diagnosed with HFrEF and 46 (21%) with HFpEF. Patients with HFpEF had lower baseline exercise capacity compared to those with HFrEF. Participating in a 6 month exercise program resulted in significant and similar improvement in exercise performance of both HFpEF and HFrEF patients: an absolute metabolic equivalent (MET) change (1.45 METs in HFrEF patients vs. 1.1 in the HFpEF group, P = 0.3).

Conclusions: An exercise training program resulted in similar improvement of exercise capacity in both HFpEF and HFrEF patients. An individualized, yet similarly structured, cardiac rehabilitation program may serve both heart failure groups, providing safety and efficacy.

Background: Type 2 diabetes mellitus is a multifactorial disease in which genetic susceptibility and environmental factors induce pancreatic β-cell dysfunction and insulin resistance. Additional factors such as hyperglycemia and hyperlipidemia have roles in β-cell dysfunction and disease progression. The phenomenon of lipid-induced pancreatic β-dysfunction, designated as lipotoxicity, has been observed in several in vitro and in vivo experiments; however, there is still no solid evidence for the occurrence of this event in humans. The toxic effect of high lipid levels on β-cell function consists of impaired insulin gene expression, apoptosis, and reduced glucose-stimulated insulin secretion.

Objectives: To demonstrate the importance of treating hypertriglyceridemia in reducing glucose intolerance and the need for insulin therapy in hospitalized diabetic patients.

Methods: We evaluated five clinical case reports and conducted a detailed literature review via the PubMed search engine.

Results: Reduction in elevated blood triglyceride and glucose levels in hospitalized diabetic patients resulted in a rapid decline in glucose levels and in the need for insulin therapy.

Conclusions: A decrease in high triglyceride levels in “lipotoxic” diabetic patients may improve insulin intolerance and glucose homeostasis and reduce the need for insulin therapy.

Background: Williams syndrome (WS) is a neurogenetic syndrome characterized by a variety of medical conditions and cognitive deficits along with distinct psychiatric and behavioral characteristics. To the best of our knowledge, no studies to date have comprehensively reported the prevalence of medical, cognitive deficits, and psychiatric disorders in one cohort of people with WS in one study.

Objectives: To detail the prevalence of the various clinical features of WS in a large nationwide Israeli cohort. To examine potential risk factors for attention deficit hyperactivity disorder (ADHD) in WS.

Methods: We investigated the effects of cardiovascular anomalies, intellectual quotient (IQ), and phonophobia (fear of sounds) on the likelihood of ADHD. The study included 80 participants with WS (mean age 7.76 years). Relevant medical information from medical records was obtained retrospectively. In addition, IQ testing and psychiatric assessments using structured tools were conducted. The association between ADHD and cardiovascular anomalies, IQ, and phonophobia was analyzed using a logistic regression.

Results: Supravalvular aortic stenosis and supravalvular pulmonary stenosis are the prevalent cardiovascular anomaly in WS. Phonophobia and ADHD are the most prevalent psychiatric diagnoses in people with WS. Phonophobia was significantly associated with the risk for ADHD in WS participants.

Conclusions: Our findings regarding the type and prevalence of medical, cognitive, and psychiatric characteristics in WS correspond to results in previous publications. We also showed a potential link between phonophobia and ADHD that merits further research.

Background: Vitamin D deficiency and insufficiency have been reported in fibromyalgia. However, to the best of our knowledge, only one study has evaluated the role of 25-hydroxyvitamin D [25(OH)D] supplementation on fibromyalgia symptoms.

Objectives: To analyze the effects of 3 months of 25(OH)D supplementation on symptoms of fibromyalgia.

Methods: This study included 11 female patient. Demographic and clinical data, tender points, visual analog scale results, and pre- and post-serum levels of 25(OH)D supplementation were analyzed. The levels of 25(OH)D were measured by a radioimmunologic test.

Results: Patients with fibromyalgia diagnosis and 25(OH)D values ≤ 30 ng/ml were recruited to receive 50,000 IU of oral vitamin D once every week for 3 months. The disease was diagnosed based on the American College of Rheumatology criteria. The median age of all patients was 48.5 (28–67) years and 63.4% were Caucasian. Disease duration varied from 1–10 years. The 25(OH)D levels increased significantly after 3 months, 18.4 (15.5–25.8) ng/ml vs. 33.8 (28–58) ng/ml, P = 0.01. Interestingly, an improvement of visual analog scale scores was observed at 3 months, 90 (0–100) vs. 30 (0–80), P = 0.002. Eight patients (72.2%) responded that they experienced a very significant improvement in symptoms. In addition, a trend for reduction of the number of tender points was observed after 3 months, 17 (11–18) vs. 10 (0–18), P = 0.07.

Conclusions: The 25(OH)D levels and disease symptoms in patients with fibromyalgia and vitamin D deficiency/insufficiency seem to improve with vitamin D supplementation.

Background: Limited information exists about detailed clinical characteristics and management of the small subset of Brugada syndrome (BrS) patients who had an arrhythmic event (AE).

Objectives: To conduct the first nationwide survey focused on BrS patients with documented AE.

Methods: Israeli electrophysiology units participated if they had treated BrS patients who had cardiac arrest (CA) (lethal/aborted; group 1) or experienced appropriate therapy for tachyarrhythmias after prophylactic implantable cardioverter defibrillator (ICD) implantation (group 2).

Results: The cohort comprised 31 patients: 25 in group 1, 6 in group 2. Group 1: 96% male, mean CA age 38 years (range 13–84). Nine patients (36%) presented with arrhythmic storm and three had a lethal outcome; 17 (68%) had spontaneous type 1 Brugada electrocardiography (ECG). An electrophysiology study (EPS) was performed on 11 patients with inducible ventricular fibrillation (VF) in 10, which was prevented by quinidine in 9/10 patients. During follow-up (143 ± 119 months) eight patients experienced appropriate shocks, none while on quinidine. Group 2: all male, age 30–53 years; 4/6 patients had familial history of sudden death age < 50 years. Five patients had spontaneous type 1 Brugada ECG and four were asymptomatic at ICD implantation. EPS was performed in four patients with inducible VF in three. During long-term follow-up, five patients received ≥ 1 appropriate shocks, one had ATP for sustained VT (none taking quinidine). No AE recurred in patients subsequently treated with quinidine.

Conclusions: CA from BrS is apparently a rare occurrence on a national scale and no AE occurred in any patient treated with quinidine.

Background: Recent studies have analyzed risk factors associated with complications after gastric cancer surgery using the Clavien-Dindo classification (CD). However, they have been based on Asian population cohorts (Chinese, Japanese, Korean).

Objectives: To prospectively analyze all post-gastrectomy complications according to severity using CD classification and identify postoperative risk factors and complications.

Methods: We analyzed all gastrectomies for gastric cancer performed 2009–2014. Recorded parameters included demographic data, existing co-morbidities, neo-adjuvant treatment, intra-operative findings, postoperative course, and histologic findings. Postoperative complications were graded using CD classification.

Results: The study comprised 112 patients who underwent gastrectomy. Mean age was 64.8 ± 12.8 years; 53 patients (47%) underwent gastrectomy, 37 (34%) total gastrectomy, and 22 (19%) total extended gastrectomy. All patients had D2 lymphadenectomy. The average number of retrieved lymph nodes was 35 ± 17. Severe complication rate (≥ IIIa) was 14% and mortality rate was 1.8%. In a univariate analysis, age > 65 years; ASA 3 or higher; chronic renal failure; multi-organ resection; and tumor, node, and metastases (TNM) stage ≥ IIIc were found to be significantly associated with CD complication grade > III (P = 0.01, P = 0.05, P = 0.04, P = 0.04, and P = 0.01, respectively). Multivariate regression analysis revealed advanced stage (≥ IIIc) and age > 65 years to be significant independent risk factors (P < 0.05).

Conclusions: Age > 65 and advanced stage (≥ IIIc) were the primary risk factors for complications of grade > III according to the CD classification following gastrectomy for gastric cancer.

Background: Acute musculoskeletal pain is one of the most commonly reported symptoms among patients visiting the emergency department (ED). Treatment with over-the-counter pain medications, given by nurses, results in improved pain management and reduces the waiting time to drug administration without significant side effects. Opioid analgesics are extensively used for acute pain in the ED. Compared to morphine, oxycodone has a much more specific pharmacological activity, higher analgesic potential, and more tolerable side effects.

Objectives: To assess the degree of pain reduction using different protocols, including dypirone and oxycodone given by nurses, in treating acute musculoskeletal pain in the emergency department (primary outcome) and to evaluate the need for rescue medications (secondary outcome).

Methods: This observational prospective clinical trial compared two groups of 50 patients, each one visiting the ED due to musculoskeletal pain. One group was treated with dipyrone syrup and the other was treated with oxycodone syrup. The primary outcome was pain reduction measured by the Numeric Rating Scale (NRS). The secondary outcome was the difference in need for rescue medications.

Results: The reduction in the NRS was greater in the patients treated with oxycodone. This finding was statistically and clinically significant (P < 0.001). The need for rescue medications was also significantly reduced in this group of patients (P = 0.007).

Conclusions: This study showed that the administration of over-the-counter oxycodone syrup by nurses decreases the post-treatment pain reported by patients, reduces the need for rescue medications, and increases the satisfaction of the medical staff.
