Birth helpers touch the parturient woman in many ways. They make physical contact to diagnose difficulties and manipulate safe delivery.

They may also touch the woman in non-physical ways, with special words, as they help a woman to give birth. Some hope also for a divine touch, as Jewish tradition teaches that God is a partner in the birth process.

This paper takes a historical look at the different forms of touch used by birth attendants to ease the safe arrival of a healthy infant.

We hope that this short retrospective will encourage today's birth helpers, especially doctors and midwives, to notice how they themselves touch birthing women. We hope to promote awareness of the verbal and non-verbal language of touch and to encourage the use of the art of touch among medical staff who are now more skilled than ever before in applying scientific touch to patients.
 

Systemic infection or inflammation causes a decrease in intestinal iron absorption and impairs the release of recycled iron from macrophages. Decreased availability of iron may deny this essential element to invading pathogens and may inhibit their multiplication and other metabolic processes but also results in anemia of chronic disease. This article reviews recent discoveries that shed light on the regulation of iron metabolism during infection and iron overload, and point to the central role of a newly discovered peptide, hepcidin. Evidence to date indicates that hepcidin is a negative regulator of intestinal iron absorption, placental iron transport, and the release of iron from macrophages that recycle iron from senescent red cells. It may also be the central mediator of iron sequestration during infections and inflammatory states and the mediator of anemia of chronic disease. Rapid progress in this area is a good example of the beneficial effects of improvements in peptide analysis and chemistry, advances in genomics, and the increasing use of transgenic mice to determine the function of newly discovered genes and proteins.

Background: Although Listeria monocytogenes is widely distributed in nature, it rarely causes clinical infection in previously healthy people. This microorganism. however, may cause severe invasive disease in pregnant women and newborns.

Objectives: To investigate – in our pregnant population – the impact, severity and outcome of listeriosis on both mother and fetus.

Method: The study was carried out at a level III, university two-hospital complex, In a retrospective chart review of 65,022 parturients during a 10 year period (1990-1999), we identified and: evaluated 11 pregnant patients and their offspring with Listeria infection;

Results: Chorioamnionitis with multiple. placental abscesses were observed in all five placentae examined. Clinically 4 of 11 parturients had a cesarean section for fetal distress (36.3%), as compared to the 14% mean CS rate in our general population. Two of 11 had a fate abortion (18.1%), as compared with the 4% rate in our hospital. Four of 11 had premature labor (36%), which was about four times the rate in our population. Finally, although no intrauterine feta1 death was recorded in our series, there was one neonatal death of a term infant. (1/11, 9%), which is about 10 times higher than our corrected perinatal mortality rate.

Conclusions: If not promptly and adequately treated, listeriosis in pregnancy may present serious hazards to the fetus and newborn through direct infection-of the placenta and chorioamnionitis.
 

Background: Low density lipoprotein apheresis is used as a complementary method for treating hypercholesterolemic patients who cannot reach target LDL[1]-cholesterol levels on conventional dietary and drug treatment. The DALI system (direct absorption of lipoproteins) is the only extracorporeal LDL-removing system compatible with whole blood.

Objective: To describe our one year experience using the DALI[2] system.

Methods: LDL apheresis was used in 13 patients due to inability to reach target LDL-C levels on conventional treatment. They included seven patients with familial hypercholesterolemia, three who had adverse reactions to statins, and three patients with ischemic heart disease who did not reach LDL-C target level on medical treatment.

Results: The average triglyceride, total cholesterol, high density lipoprotein-C and LDL-C levels before and after treatment in all patients were: 170 ± 113 vs. 124 ± 91, 269 ± 74 vs. 132 ± 48, 42 ± 8 vs. 37 ± 7.9, and 196 ± 77 vs. 80 ± 52 mg/dl, respectively. Comparing the results of a subgroup of seven patients who had previously been treated with plasma exchange, it is noteworthy that while the reduction in triglyceride, total cholesterol and LDL-C are comparable, the effect on HDL[3]-C concentration was less apparent: from an average of 39.7 ± 8.7 and 23 ± 5.7 mg/dl before and after plasma exchange to an average of 43.9 ± 8.1 and 38.4 ± 7 mg/dl before and after LDL apheresis, respectively. Five patients developed treatment-related adverse events: three experienced allergic reactions manifested as shortness of breath, urticaria and facial flushing; one patient developed rhabdomyolysis, an adverse reaction that was not reported previously as a result of LDL apheresis; and one patient had myopathy with back pain. All untoward effects occurred during the first few treatment sessions.

Conclusions: LDL apheresis using the DALI system is highly efficacious for the treatment of hypercholesterolemia. It is associated with a significant number of side effects occurring during the first treatment sessions. In patients not experiencing adverse effects in the early treatment period, it is well tolerated, and can provide remarkable clinical benefit even after short-term therapy.

Recent studies have implicated the dying cell as a potential reservoir of modified autoantigens that may initiate and drive systemic autoimmunity in susceptible hosts. The uridine-rich small nuclear ribonucleoprotein complex is a common target for autoantibodies present in the serum of patients with systemic lupus erythematosus and SLE[1]-overlap syndromes. Four modifications occurring in this complex during apoptosis have been described to date: the caspase-mediated cleavage of the U1-70K protein, the U1 RNA and the Sm-F protein, and the association with hyperphosphorylated SR proteins. In addition, the U1 snRNP[2] complex has been shown to translocate from its normal subcellular localization to apoptotic bodies near the surface of cells undergoing apoptosis. This redistribution might facilitate exposure of the modified components of the U1 snRNP complex to the immune system when the clearance of apoptotic cell remnants is somehow disturbed. The modifications in the U1 snRNP components during apoptosis might represent the initial epitopes to which an immune response is generated and may be the trigger for the production of autoantibodies to this complex in patients with SLE or SLE-overlap syndromes. Therefore, it can be hypothesized that the exposure of elevated levels of apoptotically modified U1 snRNP to the immune system of a genetically susceptible individual might lead to the breaking of immunologic tolerance towards the U1 snRNP complex.

Southern Sinai, a mountainous desolated arid area, is inhabited by Bedouin nomad tribes composed of Arabic-speaking Moslems. Until the Six Day War between Egypt and Israel in 1967, healthcare services in the region were based on traditional medicine performed by the Darvish, a local healer. Over the course of Israeli rule (1967-1982) an elaborate healthcare service was established and maintained, providing modern, up to date, comprehensive medical services that were available to all free of charge.

Background: Long-term follow-up in apical hypertrophic cardiomyopathy is rare.

Objective: To study the natural history of the disease.

Methods: We followed 11 patients, 5 women and 6 men, for 5-20 years.

Results: At presentation all 11 patients had typical features of apical hypertrophic cardiomyopathy, with dyspnea in 3 and chest pains in 8, of whom 5 were typical of angina and 3 had myocardial infarction. R-wave voltage and T-wave negativity progressively decreased in magnitude at serial electrocardiograms in four patients. Perfusion defects were detected on thallium myocardial scintigraphy in three, increased apical uptake in two, and normal in one patient. Apical aneurysm with normal coronary arteries developed in a patient who had sustained ventricular tachycardia. All of the 10 catheterized patients had normal coronaries except for one with significant left anterior descending artery stenosis and another with a minor lesion. Symptomatic sustained ventricular tachycardia was found in two patients, one of whom required the implantation of an internal cardioverter-defibrillator.

Conclusions: Apical hypertrophic cardiomyopathy may develop morphologic and electrocardiographic changes with life-threatening arrhythmias necessitating close follow-up and treatment.

Background: Visual interpretation of fetal heart rare monitoring is subject to intra and inter observer variability.

Objective: To examine the effect of intrapartum administration of meperidine and promethazine on fetal heart activity measured by a computerized system.

Methods: Fourteen healthy women with normal pregnancies at term were studied during the active phase of labor. Fetal heart rate was recorded with the Oxford Sonicaid system 8000. Recordings were performed for 40 minutes prior to and after maternal intravenous administration of meperidine 50 mg with promethazine 25 mg.

Results: The combination of meperidine and promethazine caused a significant decrease in the number of accelerations of 10 beats per minute (9.7 versus 2.6, P = 0.002) and 15 beats per minute (5.2 vs. l.4, P = 0.003), time spent in episodes of high variation (14.8 vs. 2.0, P = 0.005) and short-term variation (7.8 vs. 5.0, P = 0.003). On the other hand there was an increase in the time spent in episodes of low variation (5.3 vs. 19.7, P = 0.009).

Conclusions: Maternal administration of meperidine with promethazine has a significant effect on FHR[1] indices during the active phase of normal labor.

Background: Each winter influenza activity is a major cause of morbidity and mortality both in Israel and worldwide.

Objectives: To identify the influenza viruses active in Israel during the winter season and to assess the extent of influenza morbidity.

Methods: Information was collected on a population of 18,684 individuals enrolled in two community clinics in central Israel. It included the total number of visits for acute respiratory infection – including influenza and influenza-like illness (ARI/flu-like) – during a 20 week surveillance period (23 November 1997 to 27 March 1998) and the percent of influenza virus isolates in nasopharyngeal specimens from a sample of patients with ARI/flu-like collected on a weekly basis during the same period.

Results: A total of 5,947 visits for ARI/flu-like were recorded among 18,684 enrolled patients in two community clinics (18.1%). The progressive increase in the number of visits for ARI/flu-like reached a peak on week 2/98 with 597 visits and a rate of 31.95 visits per 1,000 population. After this, a decrease to the initial values was evident by week 12/98. Most affected patients were in the age groups 5–14 and 65 years and over, with a rate of 733.5 and 605.3 visits per 1,000 population, respectively. Influenza virus was isolated from 92 of the 426 nasopharyngeal specimens (21.6%). The most commonly detected strain was A/Sydney/5/97(H₃N₂) like (77.2%). The peak rate of isolates was recorded at the beginning of January (01/98).

Conclusions: A/Sydney/5/97(H₃N₂) like-strain was the dominant influenza virus. Its presence did not prevent the simultaneous activity of influenza A/H₁N₁ virus. The dynamic of the clinical disease as expressed by the weekly visit rate for ARI/flu-like was similar to the temporal pattern of the virological findings. The extent of morbidity suggests moderate epidemic activity.
 

Background: Spinal dural arteriovenous fistulae comprise the majority of spinal vascular malformations. The most common clinical presentation is that of progressive myelor­adicuiopathy, probably related to venous hypertension, which may lead to permanent disability and even death.

Objective: To report our clinical experience with spinal dural arteriovenous fistulae.

Methods: Nine patients with spinal dural AVF were managed at our center during a one year period (1998-1999). The patients, eight men and one woman ranging in age from 46 to 75 years, presented with initially fluctuating and eventually permanent and progressive paraparesis, sensory disturbances and sphincter dysfunction. The neurological signs generally began symmetrically and progressed from the distal to proximal limb regions. The duration of symptoms before diagnosis ranged from 6 to 36 months during which the patients underwent an extensive but fruitless work-up and even unnecessary operations due to misdiagnosis. All patients finally underwent magnetic resonance imaging and spinal angiography, which demonstrated the pathological vascular fistula. Interruption of the AVF was achieved by embolization or by surgical resection.

Results: Following treatment, six patients experienced improvement of gait and sphincter control, and the severe neurological deficits stabilized in the other three patients with long duration of illness. There was no further deterioration in any of the treated patients.

Conclusions: The history, neurological findings and radiological changes on MRI scan should alert clinicians to the possibility of spinal dural AVF, leading to diagnostic spinal angiography. Early diagnosis and treatment may significantly improve outcome and prevent permanent disability and even mortality.

Background: On 1 January 1995 a new mandatory National Health Insurance Law was enacted in Israel, The new law fostered competition among the four major Israeli healthcare providers (HMO5 or sick funds) already operating in the market due to the possibility that an unlimited number of patients and the relative budget share would shift among the HMOs. This led them to launch advertising campaigns to attract new members.

Objectives: To examine newspaper advertising activities during the early stages of healthcare market reform in Israel.

Methods: Advertising efforts were reviewed during a study period of 24 months (July 1994 to June 1996). Advertisements were analyzed in terms of marketing strategy, costs and quality of information.

Results: During the study period 412 newspaper adver­tisements were collected. The total advertising costs by all HMOs was approximately US$4 million in 1996 prices. Differences were found in marketing strategy, relative adver­tising costs, contents and priorities among the HMOs.

Conclusions: The content of HMO5 newspaper advertis­ing was consistent with their marketing strategy. The mes­sages met the criteria of persuasive advertising in that they cultivated interest in the HMOs but did not provide meaningful information about them. Future developments in this area should include consensus guidelines for advertising activities of HMOs in Israel, instruction concerning the content of messages, and standardization of criteria to report on HMO performance.
