Background: Virtual reality immersion has been advocated as a new effective adjunct to drugs for pain control. The attenuation of pain perception and unpleasantness has been attributed to the patient's attention being diverted from the real, external environment through immersion in a virtual environment transmitted by an interactive 3-D software computer program via a VR[1] helmet.

Objectives: To investigate whether VR immersion can extend the amount of time subjects can tolerate ischemic tourniquet pain.

Methods: The study group comprised 20 healthy adult volunteers. The pain was induced by an inflated blood pressure cuff during two separate, counterbalanced, randomized experimental conditions for each subject: one with VR and the control without VR exposure. The VR equipment consisted of a standard computer, a lightweight helmet and an interactive software game.

Results: Tolerance time to ischemia was significantly longer for VR conditions than for those without (P < 0.001). Visual Analogue Scale (0–10) ratings were recorded for pain intensity, pain unpleasantness, and the time thought about pain. Affective distress ratings of unpleasantness and of time thought about pain were significantly lower during VR as compared with the control condition (P < 0.003 and 0.001 respectively).

Conclusions: The VR method in pain control was shown to be beneficial. The relatively inexpensive equipment will facilitate the use of VR immersion in clinical situations. Future research is necessary to establish the optimal selection of clinical patients appropriate for VR pain therapy and the type of software required according to age, gender, personality, and cultural factors.

Background: Debate continues in Israel as to whether to allow patients in public hospitals to choose their physician in return for an additional, out-of-pocket payment. One argument against this arrangement is that the most senior physicians will devote most of their time to private patients and not be sufficiently available to public patients with complex cases.

Objectives: To analyze the patterns of surgical seniority in Jerusalem hospitals from a number of perspectives, including the extent to which: a) opting for private care increases the likelihood of being treated by a very senior surgeon; b) public patients undergoing complex operations are being treated by very senior surgeons, c) the most senior surgeons allocate a significant portion of their time to private patients.

Methods: Demographic and clinical data were retrieved from the operating room records of three of the public hospitals in Jerusalem for all 38,840 operations performed in 2001. Of them, roughly 6000 operations (16%) were performed privately. Operations were classified as "most complex," "moderately complex" and "least complex" by averaging the independent ratings of eight medical and surgical experts. The surgeon's seniority was graded as "tenured" (tenured board-certified specialists, including department heads), "senior" (non-tenured board-certified specialists), and "residents." For each operation, we considered the seniority of the lead surgeon and of the most senior surgeon on the surgical team.

Results: The lead surgeon was of tenured rank in 99% of the most complex private cases and 74% of the most complex public cases, in 93% of the moderately complex private and 35% of the moderately complex public cases, and in 92% of the least complex private and 32% of the least complex public cases. The surgical team included a tenured physician in 97%, 66%, and 53% of the most complex, moderately complex, and least complex public operations, respectively. In both private and public cases, a board-certified (tenured or senior) specialist was a member of the surgical team for almost all of the most complex and moderately complex operations. On average, over half of the operations in which the lead surgeon was a department head were performed on public patients. Among tenured surgeons, those who spent more hours than their colleagues leading private operations also tended, on average, to spend more hours leading public operations.

Conclusions: Private patients have an advantage over public patients in terms of the seniority of the lead surgeon. However, there is also substantial involvement of very senior surgeons in the treatment of public patients, particularly in those cases that are most complex. 

Background: We recently published preliminary evidence on the effectiveness of hypertonic saline in infants with viral bronchiolitis.

Objective: To further establish the efficacy of nebulized hypertonic saline in these infants

Methods: In a continuing, second-year randomized, double-blind controlled trial, an additional 41 infants (age 2.6 ± 1 months) hospitalized with viral bronchiolitis were recruited during the winter of 2001–2002. The infants received inhalation of 1.5 mg epinephrine dissolved either in 4 ml normal (0.9%) saline (Group I, n=20) or 4 ml hypertonic (3%) saline (Group II, n=22). The therapy was repeated three times daily until discharge. Pooling our 2 years of experience (2000–2002), a total of 93 hospitalized infants with viral bronchiolitis were recruited; 45 were assigned to Group I and 48 to Group II.

Results: The clinical scores at baseline were 7.6 ± 0.7 for Group I vs. 7.4 ± 1.3 for Group II (P = NS). However, the clinical scores at days 1 and 2 after inhalation differed significantly between the two groups, invariably favoring Group II: 7 ± 1 vs. 6.25 ± 1.1 (P < 0.05), 6.45 ± 1 vs. 5.35 ± 1.35 (P < 0.05), respectively. Adding aerosolized 3% saline to 1.5 mg epinephrine reduced the hospitalization stay from 3.5 ± 1.7 days in Group I to 2.6 ± 1.4 in Group II (P < 0.05). The pooled data of both years revealed that adding 3% saline to the inhalation mixture decreased hospitalization stay from 3.6 ± 1.6 to 2.8 ± 1.3 days (P < 0.05).
Conclusions: This second-year experience and our 2 year pooled data analysis strengthen the evidence that the combination of 3% saline/1.5 mg epinephrine benefits hospitalized infants with viral bronchiolitis

Background: The suspicion of child abuse and neglect may arise from manifestations such as physical or psychosomatic symptoms, eating disorders, suicidal behavior, impaired parental functioning, etc. Thus the arrival of an abused or neglected child at the hospital provides an opportunity for detecting the problem and beginning a process of change. Optimal utilization of this potential depends on the awareness, diagnostic ability and cooperation of the staff.

Objectives: To assess knowledge about hospital policy, attitudes and actual behavior of hospital staff in cases of SCAN[1].

Methods: The questionnaire was adapted and distributed to a convenience sample of personnel at a children’s hospital. The questionnaire included items on knowledge of hospital policy regarding SCAN, attitudes towards inquiring about cases that appear suspicious, and behaviors in cases in which the respondent was involved. The comparison of responses to specific questions and among members of different professions was analyzed by chi-square test.

Results: Eighty-two staff members completed the questionnaires. Most of the respondents were aware of hospital policy regarding suspected abuse (86.6%), with fewer regarding suspected neglect (77.2%). Physicians were the least aware of these policies, as compared to medical students, nurses and social workers. Although most considered the issue of SCAN a responsibility of members of their own profession, 35.4% considered it primarily the responsibility of the welfare or judicial systems. Over 40% felt uncomfortable discussing suspicions with the child and nearly half felt uncomfortable discussing them with parents. The most often reported reason for this was the sense that they lacked skills or training for dealing with the issue. Despite this, when asked about actual behavior, 94.7% responded that they do try to clarify the circumstances related to the suspicious symptoms. Respondents were more likely to contact the hospital social worker than community resources (91.5% vs. 47.2%).

Conclusions: The findings highlight the need to encourage awareness, discourse and training of medical personnel about issues related to SCAN in order to maximize their potential contribution to identifying children at risk.

Endometrial polyps are a frequent finding in infertile patients. Little is known about the true prevalence of polyps in infertile patients. It is unproved whether polyps are causative of infertility, or whether surgical polypectomy by hysteroscopy improves the likelihood of successful conception. This article reviews endometrial polyps in reproductive-age fertile and infertile women.

Background: Intramural duodenal hematoma generates partial or complete obstruction that develops slowly and progressively with a consequent delay in diagnosis. Many diagnostic and therapeutic measures remain debatable and justify a review of current management policy.

Objectives: To highlight the diagnostic and therapeutic steps in pediatric IDH[1].

Methods: The records of 12 children with post-traumatic IDH who were treated in the Hillel Yaffe Medical Center between 1986 and 2000 were retrospectively reviewed. Three of them had clotting disorders and were excluded. The interval between their admission and diagnosis as well as the therapeutic decisions were evaluated and analyzed.

Results: Nine children were treated for IDH. The interval between admission and diagnosis ranged from 24 hours to 6 days. Five children had associated traumatic pancreatitis. Initially, all the children were conservatively treated. In seven the hematoma resolved after 9–20 days. Two children were operated upon because the obstruction failed to resolve. All nine children recovered without permanent complications.

Conclusions: Intramural duodenal hematoma has many clinical and therapeutic puzzling aspects. Bicycle handlebar, road accidents and sports trauma are the main etiologic factors in children, but child abuse should be kept in mind. Associated traumatic pancreatitis is common. Gastroduodenal endoscopy may be useful to clarify doubtful cases. Pediatric surgeons should increase awareness regarding IDH in order to reduce delay in diagnosis and the need for surgical decompression.

The care of the trauma victim can be divided into five to six phases, none of which can be bypassed.

Background: In the last decade there has been an increase in asthma morbidity. Hospital admission rates for childhood asthma are influenced by the prevalence of asthma and the quality of asthma care.

Objective: To assess trends in hospital admission and readmission rates for childhood asthma in the Jezreel Valley in Israel in the last decade, and to evaluate the possible effect of changes in asthma treatment upon hospitalization for acute asthma during this period.

Methods: All records from pediatric patients from the central hospital in the Jezreel Valley in northeastern Israel over a 10 year period from 1990 through 1999 who were diagnosed as having asthma were thoroughly reviewed and analyzed for admissions, re-admissions, and treatment before and during admissions

Results: There were 1584 admissions, 1208 were first-time admissions and 374 were re-admissions. The number of first-time admissions increased significantly over time (P < 0.0001), with a significant decrease of re-admissions (P < 0.005); this finding was more significant in children under the age of 8 years (P < 0.005). The length of hospital stay decreased significantly from 3.3 days to 2.7 days (P < 0.002). Significant changes in the use of medications included an increase in inhalant glucocorticoids and a decrease in the use of sodium cromoglycate and theophylline. Controller medication use was concomitant with a significant decrease in the re-admission rates.

Conclusions: The increase in the admission rate and the decrease in the rate of re-admissions and the length of hospital stay probably reflect the increase in the prevalence of asthma and changes in its treatment, respectively. It is essential that asthma be recognized as a significant cause of morbidity and that controller medications be administered to decrease the asthma's severity, morbidity, and resultant hospital admissions.
 

Background: Analysis of the trends in psychiatric admissions and discharges is necessary to correctly plan and distribute resources, especially given the current international climate of “deinstitutionalization." Israel, too, is implementing “reform” in the national psychiatric system – to transfer psychiatric treatment from a hospital to a community setting

Objectives: To analyze admission and discharge patterns, explore trends in psychiatric hospital length of stay, and compare these characteristics between first-episode and chronic patients, between children, youth and adults, and between hospitals.

Methods: All admissions and discharges from inpatient psychiatric wards between the years 2000 and 2004 were analyzed and characterized according to age, length of hospitalization, legal status, and nature of admitting institution (state hospital, health fund, general hospital).

Results: Mean length of stay in adults decreased during the 5 year study period, from 37.6 days in 2000 to 36.4 days in 2004. In years with higher admissions, hospital stay was shorter (P < 0.05). Length of stay in psychiatric wards in general hospitals was shorter than in state hospitals (P < 0.001). In contrast to adults and children, length of stay among adolescents showed a gradual increase (P < 0.05). Involuntary hospitalization comprised 25.3% of all admissions, and 16.8% of discharged patients were readmitted within 30 days. A dramatic decrease (24.3%) in the number of chronic hospitalizations was noted.

Conclusions: Various factors may account for these developments. Protracted hospitalizations may be reduced through changes in various aspects of treatment planning and psychiatric care continuum. The decrease in number of admissions, length of stay and number of chronically admitted patients remains in line with international practices. Particular attention needs to be devoted to planning and funding so that availability of community services matches reduction in psychiatric hospitalization.
 

Background: Chlorpromazine is a dopamine-receptor antagonist antipsychotic agent. Because of its strong alpha-blocking and sedative actions, it has also been used as emergency therapy for extreme arterial hypertension. Published reports to date have included very small numbers of patients (i.e., 5–30).

Objectives: To analyze data on almost 500 patients who received intravenous chlorpromazine for the emergency treatment of uncontrolled symptomatic hypertension in the pre-hospital setting.

Methods: We reviewed data from 496 consecutive patients who received intravenous chlorpromazine as emergency therapy for uncontrolled symptomatic hypertension. Chlorpromazine was injected intravenously. The dose was 1 mg every 2–5 minutes until the systolic pressure was -<140 mmHg and the diastolic pressure -<100 mmHg with alleviation of symptoms.

Results: The mean dose of chlorpromazine administered was 4.5 +- 5 mg (range 1–50 mg). Only 33 patients (7%) required >10 mg. Chlorpromazine reduced the systolic blood pressure from 222.82 +- 26.31 to 164.93 +- 22.66 mmHg (P < 0.001) and the diastolic blood pressure from 113.5 +- 16.63 to 85.83 +- 11.61 mmHg (P < 0.001). The sinus rate decreased from 97.9 +- 23.5 to 92.2 +- 19.7 beats per minute (P < 0.001). These results were achieved within the first 37 +- 11 minutes.

Conclusions: Intravenous chlorpromazine is safe and effective when used as emergency treatment for uncontrolled symptomatic hypertension.

In the last few decades there has been a tendency towards reinstitutionalization.

Objectives: To examine whether hostility, anxiety and autobiographical memory (a correlate of depression) are associated with IIH[1].

Methods: Using a case-control cross sectional design, 20 patients with IIH were compared with 9 healthy controls of similar age, weight and height, and 11 headache controls. Patients were assessed for hostility and anxiety. The Autobiographical Memory Test was used to assess episodic memories.

Results: The IIH group reported significantly more anxiety and more general episodic memories than the healthy controls, but not the headache control group. The headache control patients reported more general memories than did the healthy controls.

Conclusions: Patients with headaches, whether of general origin or related to IIH, have a poor psychosocial profile. While the study design does not permit any conclusions regarding causality, our results support the need to consider psychological factors in evaluating and treating IIH and headache patients.
