Background: Bowel ultrasound has several possible uses in inflammatory bowel disease (IBD), including the initial evaluation of suspected IBD, monitoring of therapeutic response, detection of relapse, and diagnosis of complications as well as of extra-intestinal manifestations. However, its use has been limited mainly to countries where it is performed by the attending physician. 

Objectives: To investigate the feasibility and sensitivity of bedside bowel ultrasound performed by a gastroenterologist for assessing disease activity and complications in IBD.

Methods: We performed a feasibility study to compare the results of bowel ultrasound examination with those of another cross-sectional imaging modality (computed tomographic enterography or magnetic resonance enterography) in Crohn's disease, or with colonoscopy in ulcerative colitis.

Results: Between May 2015 and March 2016, 178 bowel ultrasound examinations were performed in 178 patients with suspected or established diagnosis of IBD. In 79 cases the results of another cross-sectional imaging or endoscopic examination performed within 3 months prior to the ultrasound exam were available. The sensitivity for detection of intestinal bowel thickening (a surrogate of inflammation) was 90%, and for detection of Crohn's disease complications, namely bowel stenosis and inflammatory mass, was 94% and 75%, respectively.

Conclusions: Bowel ultrasound is a useful and feasible bedside imaging tool for the detection of inflammation and complications in IBD patients. Bedside bowel ultrasound can be a valuable non-invasive tool to assess disease activity and complications in IBD patients when performed by the attending physician.

 

Background: Warm compresses are widely touted as an effective treatment for ocular surface disorders. Black tea compresses are a common household remedy, although there is no evidence in the medical literature proving their effect and their use may lead to harmful side effects. 

Objectives: To describe a case in which the application of black tea to an eye with a corneal epithelial defect led to anterior stromal discoloration; evaluate the prevalence of hot tea compress use; and analyze, in vitro, the discoloring effect of tea compresses on a model of a porcine eye.

Methods: We assessed the prevalence of hot tea compresses in our community and explored the effect of warm tea compresses on the cornea when the corneal epithelium’s integrity is disrupted. An in vitro experiment in which warm compresses were applied to 18 fresh porcine eyes was performed. In half the eyes a corneal epithelial defect was created and in the other half the epithelium was intact. Both groups were divided into subgroups of three eyes each and treated experimentally with warm black tea compresses, pure water, or chamomile tea compresses. We also performed a study in patients with a history of tea compress use. 

Results: Brown discoloration of the anterior stroma appeared only in the porcine corneas that had an epithelial defect and were treated with black tea compresses. No other eyes from any group showed discoloration. Of the patients included in our survey, approximately 50% had applied some sort of tea ingredient as a solid compressor or as the hot liquid.

Conclusions: An intact corneal epithelium serves as an effective barrier against tea-stain discoloration. Only when this layer is disrupted does the damage occur. Therefore, direct application of black tea (Camellia sinensis) to a cornea with an epithelial defect should be avoided.

 

Background: Transcatheter tricuspid valve-in-valve implantation (TVIV) is an attractive yet under-explored alternative to redo valve surgery. 

Objectives: To report the multicenter TVIV experience in Israel.

Methods: We approached multiple centers and collected data regarding seven TVIV cases. 

Results: The study group comprised seven participants: five females and two males, with a mean age of 63 ± 12 years and EuroSCORE-II 13.6 ± 3.3%. Follow-up ranged from 3 to 21 months (mean 8 ± 6 months). All presented with advanced heart failure. The indication for valve intervention was a predominant tricuspid stenosis in three patients, significant tricuspid regurgitation in one and a mixture in three. Six procedures were conducted via a transfemoral approach and one by transatrial access. The Edwards SAPIENTM XT valve was used in four cases and the SAPIENTM 3 in three. Without pre-stenting/rapid pacing, all participants underwent successful valve implantation. Mean transvalvular gradient decreased from 11 ± 3 mmHg to 6 ± 3 mmHg (P = 0.003) and regurgitation decreased from moderate/severe (in four cases) to none/trace (in six of the seven cases). One patient remained severely symptomatic and died 3.5 months after the implantation. All others achieved a functional capacity improvement and amelioration of symptoms soon after the implantation, which persisted during follow-up. 

Conclusions: TVIV may be a safe and effective strategy to treat carefully selected patients with degenerated bioprosthetic tricuspid valve at high operative risk. 

 

Background: Deliberate self-harm (DSH) increases the danger of future suicide death and the risk increases with age. Self-harm in older adults is often associated with greater suicidal intent and lethality. 

Objectives: To investigate clinical and psychosocial variables of older patients (age ≥ 65 years) assessed due to DSH, compared with younger adults.

Methods: Patients admitted to the Emergency Department following DSH during an 8 year period were included.

Results: Of 1149 participants, 187 (16.6%) were older adults (age ≥ 65) and 962 (83.4%) were younger adults (< 65). The older adults reported DSH closer to mid-day (P < 0.01) and suffered more frequently from adjustment disorder and depression. Personality disorders and schizophrenia were less commonly diagnosed (P < 0.001). Prescription medication (sedatives and hypnotics) were a more frequent means (88% vs. 71%) of DSH among older patients. Younger patients with DSH used over-the-counter medications (21.9% vs. 6.4%) three times more than did the older patients (P < 0.01). Past DSH was significantly more frequent in younger adults. Following DSH the older patients were frequently admitted for further general hospitalization (P < 0.001). 

Conclusions: Older adults with DSH are a unique group with different clinical characteristics. There is a need for targeted prevention strategies and education of caregivers regarding DSH in older adults.

 

Background: Arthritis and arthralgia are painful symptoms experienced by many elderly patients during hospitalization. Crystal-induced arthritis (CIA) is one of the most common causes of arthritis worldwide and represents the most common cause of acute arthritis in the elderly.  

Objective: To determine the incidence of both acute new onset or acute exacerbation of CIA among elderly patients hospitalized due to an acute medical illness.

Method: This study comprised 85 patients. Patients aged 70 years and older who complained of any articular pain were included in the study. Exclusion criteria were signs of septic arthritis, chronic use of steroids or non-steroidal anti-inflammatory drugs, or admission to the hospital due to an acute attack of CIA. 

Results: Synovial aspiration was performed in 76 patients (89%). Joint aspiration yielded a diagnosis in 67 of them (79%). The predominant type of crystal was calcium pyrophosphate dehydrate (68%) followed by monosodium urate (20%). The main causes of hospitalization were acute infectious disease (57%) followed by neurologic and cardiac diseases, 14% and 9% respectively, and orthopedic problems (6%). Among patients with acute infectious disease, the main causes were pulmonary (57%) and gastrointestinal (22%) infections. In 9 patients (12%) who underwent synovial aspiration, visible crystals were identified without a definite diagnosis.

Conclusion: Our study showed that hospitalization could be a risk factor for the development of CIA, and the time to diagnose CIA is during hospitalization for other acute illnesses.

 

Background: Several studies link the pathogenesis of nephrotic syndrome to tumor necrosis factor-alpha (TNFα). However, data on the serum TNFα level in children with nephrotic syndrome are sparse. 

Objective: To investigate serum TNFα levels and the effect of steroid therapy in children with nephrotic syndrome. 

Methods: A prospective cohort pilot study of children with nephrotic syndrome and controls was conducted during a 1 year period. Serum TNFα levels were measured at presentation and at remission, or after a minimum of 80 days if remission was not achieved.

Results: Thirteen patients aged 2–16 years with nephrotic syndrome were compared with 12 control subjects. Seven patients had steroid-sensitive and six had steroid-resistant nephrotic syndrome. Mean baseline serum TNFα level was significantly higher in the steroid-resistant nephrotic syndrome patients than the controls (6.13 pg/ml vs. 4.36 pg/ml, P = 0.0483). Mean post-treatment TNFα level was significantly higher in the steroid-resistant than in the steroid-sensitive nephrotic syndrome patients (5.67 pg/ml vs. 2.14 pg/ml, P = 0.001). In the steroid-resistant nephrotic syndrome patients, mean serum TNFα levels were similar before and after treatment.

Conclusions: Elevated serum TNFα levels are associated with a lack of response to corticosteroids. Further studies are needed to investigate the role of TNFα in the pathogenesis of nephrotic syndrome.

 

Background: Early surgical correction of congenital heart malformations in neonates and small infants may be complicated by acute kidney injury (AKI), which is associated with higher morbidity and mortality rates, especially in patients who require dialysis. Glomerular filtration rate (GFR) is considered the best measurement of renal function which, in neonates and infants, is highly dependent on heart function. 

Objective: To determine whether measurements of creatinine clearance after open heart surgery in neonates and young infants can serve as an early indicator of surgical success or AKI.

Method: We conducted a prospective observational study in 19 neonates and small infants (body weight < 5 kg) scheduled for open heart surgery with cardiopulmonary bypass. Urine collection measurement of creatinine clearance and albumin excretion was performed before and during surgery and four times during 48 hours after surgery.

Results: Mean creatinine clearance was lowest during surgery (25.2 ± 4. ml/min/1.73 m2) and increased significantly in the first 16 hours post-surgery (45.7 ± 6.3 ml/min/1.73 m2). A similar pattern was noted for urine albumin which was highest during surgery (203 ± 31 µg/min) and lowest (93 ± 20 µg/min) 48 hours post-surgery. AKI occurred in four patients, and two patients even required dialysis. All six showed a decline in creatinine clearance and an increase in urine albumin between 8 and 16 hours post-surgery. 

Conclusions: In neonates and small infants undergoing open heart surgery, a significant improvement in creatinine clearance in the first 16 hours postoperatively is indicative of a good surgical outcome. This finding has important implications for the early evaluation and treatment of patients in the intensive care unit on the first day post-surgery.

 

Background: Atrial fibrillation (AF) is a common complication of coronary artery bypass graft (CABG) surgery, occurring in 20%–40% of patients, mostly during the first week after surgery. It is associated with increased morbidity and mortality, but data are limited. 

Objectives: To assess the correlation between new-onset in-hospital AF following CABG and long-term AF, cerebrovascular accident (CVA), or death.

Methods: We conducted an analysis of 161 consecutive patients who underwent isolated CABG surgery in a tertiary center during the period 2002–2003. 

Results: Patients’ mean age was 72 years, and the majority were males (77%). Approximately half of the patients experienced prior myocardial infarction, and 14% had left ventricular ejection fraction < 40%. Postoperative AF (POAF) occurred in 27% of the patients. Patients were older and had larger left atrium diameter. POAF was strongly correlated with late AF (OR 4.34, 95%CI 1.44–13.1, P = 0.01) during a mean follow-up of 8.5 years. It was also correlated with long-term stroke but was not associated with long-term mortality. 

Conclusions: POAF is a common complication of CABG surgery, which is correlated with late AF and stroke. Patients with POAF should be closely monitored to facilitate early administration of anticoagulant therapy in a high risk population upon recurrence of AF. 

 

Background: Point-of-care ultrasound (POCUS) is becoming a common tool for routine use in emergency medicine, anesthesiology and intensive care for diagnostic and interventional purposes. When a portable ultrasound device became available for the department of Pediatric and Adolescent Surgery at the Schneider's Children Medical Center of Israel, we added POCUS assessments to the physician's daily rounds. POCUS is performed by pediatric surgeons trained in basic ultrasonography skills. Starting September 2015 all POCUS examinations were documented. 

Objectives: To describe the current use, diagnostic and therapeutic impacts of POCUS in a department of pediatric and adolescent surgery. 

Methods: We conducted an observational study of all the documented POCUS procedures performed during a half-year period. Data regarding patient condition and the POCUS procedures were collected, as well as data on the use of other diagnostic modalities, mainly formal ultrasound exams (by radiologists) and computed tomography scans and their correlation with the POCUS assessment. 

Results: Fifty-one POCUS exams were performed during the study period, most of which served to define the presence and resolution of a collection – intraabdominal (34%) and subcutaneous (31%). Despite a high rate for formal diagnostic studies (65%), probably due to a relative lack of confidence of surgeons performing the POCUS exams during this initial period, most results (92%) were compatible. 

Conclusions: The ability and availability to perform multiple POCUS exams by the attending physician proved to be a valuable aide to the classical physical and laboratory examinations of surgical patients, and we predict its increasing use in quotidian practice. 

Background: Medical clowns are increasingly used for diminishing pain and anxiety during painful procedures being performed on children in the hospital setting. Cortisol levels rise as a response to emotional distress. 

Objectives: To investigate whether medical clown-assisted interventions to reduce child's distress during venipuncture have an effect on cortisol levels. 

Methods: During a 1 year period, children requiring blood work or intravenous access in the pediatric emergency department were prospectively randomized to either the presence or absence of a medical clown during the procedure. The child's distress was evaluated using the Faces Pain Scale - revised (FPS-R) for the 4–7 year age group and the visual analog scales (VAS) for those aged 8–15 years. Serum cortisol levels were measured in blood samples obtained by venipuncture. 

Results: Fifty-three children aged 2–15 years were randomly assigned to the study group (with medical clown, n=29) or to the control group (without medical clown, n=24). Combined pain scores of the study group and control group were 2.2 and 7.5 respectively (P < 0.001). No difference in mean cortisol levels was found between the study group and the control group at all ages (16.4 µg/dl vs. 18.3 µg/dl, P = 0.65).

Conclusions: In this pilot study, medical clowns reduced the distress from venipuncture in children. No effect on cortisol levels was observed.
