Methotrexate Treatment in Refractory Juvenile Rheumatoid Arthritis

R. Brik

Pediatrics B Dept., Rambam Medical Center, Haifa

The mean time from initiation of methotrexate (MTX) treatment of juvenile rheumatoid arthritis (JRA) to partial remission of clinical symptoms and total clinical remission was assessed. 9 girls and 8 boys, from 3 to 18 years of age (mean 11.4±5.4) with active JRA by American College of Rheumatology (ACR) criteria (5 systemic, 8 polyarticular and 4 pauciarticular disease onset), who failed to respond to adequate courses of non-steroidal anti-inflammatory drugs (NSAID), steroids or disease-modidrugs were studied.

Clinic visits were scheduled at monthly intervals for physical and laboratory assessment disease activity and drug safety. Partial response to MTX was defined a 25% reduction of the active joint count and/or articular severity score. Total clinical remission was defined as in adult rheumatoid arthritis. The duration of disease activity until enrollment ranged from 6 months to 14 years (4.5±3.7 yr); duration of therapy was 3 months to 3 years (14.6±9.3mo) and dosage ranged from 5 to 15 mg/m²/week. Prednisone in doses below 10 mg/day and NSAID were permitted.

14 of 17 patients (82%) had a 25% reduction in joint activity after 6 weeks to 4 months (9.2±3.2 weeks); 10 (59%) went into full clinical remission after 5 to 26 months (14.3±9 months); 3 relapsed after an initial response to treatment, and 4 (23%) did not respond to MTX. The non-responders were males who required higher doses of prednisone (p<0.0001).

MTX appears to be effective therapy for children with JRA. An initial response can be expected in most patients after 9 weeks of treatment, and full clinical remission occurs after a mean of 14 months.

Ultrasonographic findings of superior sagittal sinus thrombosis include dilated and hyperechoic sinus (direct imaging of the thrombus). No flow should be demonstrated by the various Doppler techniques. In the deeper sinuses, if the thrombus can not be visualized after a negative Doppler study, MR imaging is recommended. Recanalization and reflow can be demonstrated on follow-up study.

28 in-patient units were surveyed during a 5-day period to determine the extent of the use of physical restraints in hospitalized patients. Information was gathered on the characteristics of restrained patients and indications for use and removal of restraints, patterns and means of restraints, monitoring, and written notations. 31 different patients (6% of those surveyed) were restrained in 13 units during the 5 days of the survey, an average of 15 (3%) daily.

Characteristics of restrained patients were: age 70 and over requiring emergency hospitalization, reduced level of consciousness, limitation of mobility, incontinence, history of 2 or more chronic diseases, requiring multiple drugs, and use of multiple medical devices. Bilateral, soft hand restraints were most often used to prevent patients from removing tubes. Nurses initiated the decision to apply or remove restraints, which were usually removed as the patients' condition improved. Written policies were lacking regarding monitoring and follow-up of restrained patients. Clearly written policies and increased staff awareness of potential hazards may reduce the use of restraints and the length of time they are employed.

The Mitrofanoff Pouch in Lower Urinary Tract Reconstruction

Urology Dept., Chaim Sheba Medical Center, Tel Hashomer

The Mitrofanoff principle, first described in 1980, consists of implanting a tubular organ such as the appendix, ureter, or fallopian tube into the wall of the bladder (or urinary reservoir) to create a non-refluxing, catherizable urinary conduit. Between 1993-1996, 7 men and 1 woman (aged 48-64, average 59) underwent radical cystectomy and urethrectomy combined with the creation of a MAINZ I urinary reservoir (based on the Mitrofanoff principle). In men the indication for the procedure was the diagnosis of invasive transitional cell carcinoma of the bladder with involvement of the prostatic urethra. All patients had refused urinary diversion to an ileal conduit because of its deleterious effect on the quality of life.

In all patients the postoperative course was uneventful, apart from intraperitoneal urinary leakage from the reservoir in 1, successfully managed conservatively. The patients have gained full control of urinary drainage, performing intermittent self-catheterizations every 4-5 hours. In 3 patients there were difficulties with catheterization due to stenosis of the conduit, usually at the skin level. None have suffered leakage from the reservoir, during the day, even when it was full.

Our experience shows that creation of a continent urinary reservoir according to the MAINZ I technique is an excellent surgical solution for patients in whom the creation of an orthotopic reservoir is impractical. The use of the umbilicus as a stomal site preserves normal body image and thus does not interfere with quality of life as in those undergoing radical cystectomy.

Marked obesity is an independent risk factor for multisystem morbidity. The use of anorectic drugs is an aggressive strategy for weight reduction. It appears to be an easy way of dealing with the problem, because the patient needn't change his behavior. However, such treatment is not harmless. At the end of the 60's an outbreak of pulmonary hypertension was associated with the drug aminorex, and it was soon withdrawn from the market. 30 years later it became clear that new-generation anorectic drugs (fenfluramine, dexfenfluramine, phentermine), which were being used world-wide, lead to both pulmonary hypertension and valvular damage.

We describe a woman of 70 with both these complications which developed after prolonged anorectic therapy with a fenfluramine-phentermine combination.

Spectral analysis of heart rate variability (HRV) has been shown to be a reliable noninvasive test for quantitative assessment of cardiovascular autonomic regulatory response, providing a dynamic map of sympathetic and parasympathetic interaction. In a prior study exploring the state of hyperarousal that characterizes the post traumatic stress disorder (PTSD) syndrome, we presented standardized heart rate analyses in 9 patients at rest, which demonstrated clear-cut evidence of a baseline autonomic hyperarousal state.

To examine the dynamics of this hyperarousal state, standardized heart rate analysis was carried out in 9 PTSD patients, compared to a matched control group of 9 normal volunteers. 20-minute ECG recordings in response to a trauma-related cue, as opposed to the resting state, were analyzed. The patients were asked to recount the presumed triggering traumatic event, and the control subjects recounted a significant stressful negative life event.

Whereas the control subjects demonstrated significant autonomic responses to the stressogenic stimulus of recounting major stressful experiences, the patients demonstrated almost no autonomic response to the recounting of the triggering stressful event. The patients demonstrated a degree of autonomic dysregulation at rest comparable to that seen in the control subjects' reaction to the stress model.

The lack of response to the stress model applied in the study appears to imply that PTSD patients experience so great a degree of autonomic hyperactivation at rest, that they are unable to marshal a further stress response to the recounting of the triggering trauma, as compared to control subjects. A subsequent study of the effect of medication on these parameters showed that they are normalized by use of selective serotonin re-uptake inhibitors (SSRI's).

Neither the clinical implications of these findings, nor their physiological mechanisms are clear at present. We presume that they reflect a central effect, as the peripheral automatic effects of SSRI's are relatively negligible.

Brucellosis is a classical zoonosis caused by a Gram-negative bacillus of the genus Brucella. Human brucellosis can either be acute or chronic and present with a variety of manifestations, mostly with fever and signs of musculo-skeletal involvement. It may be complicated by involvement of the cardiovascular, central nervous or genito-urinary systems. However, pulmonary brucellosis is a rare complication.

We report a case of miliary and reticulo-nodular brucellar pneumonia with positive blood and sputum cultures and positive serological tests. To the best of our knowledge this is the first case to be reported from Israel of miliary pneumonia with sputum positive for brucellosis.

Spontaneous internal jugular thrombosis is a rare vascular disorder. It usually occurs as a result of external pressure due to a tumor, infection or as a result of damage to the vessel wall after trauma or central venous catheterization. We report a 35-year-old woman who suffered from severe pulmonary hypertension due to chronic cystic lung disease. She was admitted due to sudden, severe, right-sided neck pain. Internal jugular occlusion by a thrombus was demonstrated by ultrasound and CT-scans but no apparent cause was found. We postulated that the important factors in the development of her thrombosis were stasis due to pulmonary hypertension and high blood viscosity.

During routine emergency room work penetration by foreign objects is frequently encountered, some of which may be very irregular in shape. These may cause further damage if inappropriately removed. It is important to perform a proper X-ray survey.

During the winter of 1995, nasopharyngeal colonization of Streptococcus pneumoniae was evaluated in 204 children with respiratory infection and 107 normal control children. There was no difference in gender or mean age between the groups, and no difference in carrier rate between sick (24.5%) and normal (22%) children (p=0.6). Carrier rates were 19%, 32%, 31% and 17% at 6, 12, 24 and 48 months, respectively. Penicillin-resistant pneumococci (PRP) were found in 42% of sick and 16.6% of normal children, (p<0.05). Resistance to more than 2 antibiotics was found in 28% of sick and in 12.5% of normal children. PRP were found in 67% and 34% of sick children with and without prior antibiotic treatment (p<0.05). We conclude that there is no difference in the carrier rate of Streptococcus pneumoniae between sick and normal children. However, the high prevalence of PRP in children with respiratory infections is probably due to prior antibiotic treatment.

We present 3 women who were referred for evaluation of stress-related mild-to-moderate hyperprolactinemia. This frequent finding may mistakenly be considered a clinical problem, and lead to inappropriate investigation and therapy. We emphasize the importance of serial blood sampling for prolactin determination. We collected blood samples repeatedly under resting conditions from an indwelling venous brachial catheter, every 30 minutes for a total of 6 samples. All 3 patients had normal prolactin levels 30-60 minutes after starting the test. Neither further investigation nor medical therapy were needed and these anxious patients were reassured that their hyperprolactinemia was factitious.

The Surgeon and the Emperor: a Humanitarian on the Battlefield

The Baron Dominique-Jean Larrey, one of the greatest names in military surgery, participated as Chief Surgeon in all the Napoleonic campaigns. He developed the concept of early evacuation from the battlefield, and of immediate treatment of the wounded, even under fire. He implemented improved surgical techniques and improved wound care that were followed by surgeons all over Europe. His devotion to wounded soldiers crossed national boundaries and became a way of life. Here is an account of Larrey's involvement in the aftermath of the Battles of Lutzen and Bautzen (May-June 1813), when many soldiers were accused of self-mutilation and were about to be executed. He dared to oppose, singlehanded, the Emperor, the highest military authorities and their concurring physicians and surgeons, armed only by his undisputed honesty, professional authority and exceptional reputation won over years of devotion to wounded soldiers. Larrey saved the lives of many soldiers and set an example of unbent ethical integrity.

The accidental exposure of the health care workers (HCW) to blood and blood products constitutes a danger for transmission of blood-borne pathogens and the development of severe diseases. Most attention is focused on exposure to the viruses of hepatitis B, C and human immunodeficiency. The objectives of this prospective study were to determine the rate of exposure of our HCW to blood and blood products; to define the high risk groups; and to establish recommendations to prevent transmission or reduce the risk of exposure to these viruses.

During the year 1996, 103 injuries from needle-puncture or other sharp objects were reported to our infectious diseases control unit. Most of those injured were women. 58.4% of the events occurred in the vicinity of the patient. The source of exposure was known in 60% of the cases. 73.8% of those injured had already been immunized against hepatitis B. The departments in which most exposures occurred were the operating theater (12.5%), medical departments A (10.6%) and B (9.6%), and the emergency department (7.7%). Nurses were at highest risk, constituting 47% of those injured.

Our recommendations are that a continuous teaching program be established for the high risk groups; that HCW be urged to report every event of exposure; and to encourage HCW to undergo active immunization against hepatitis B.

During 1994/5 the Japanese civilian population suffered 2 terror attacks by the organophosphorus nerve-agent sarin. In these 2 episodes it is estimated that more than 6000 people were injured, of whom 19 died. The quick and efficient response of the civilian emergency systems to these unforseen, attacks has to be analyzed by local authorities to determine the best solutions in case of another attack. We summarize the events, and note the emergency system's response, the need for rapid and accurate chemical identification of the toxin, the necessity for decontaminating the casualties and for providing protective gear for rescue units in the contaminated area. We also describe the clinical status of the casualties and outline the mode of therapy applied.

Kaleidoscopic Autoimmunity

Unit for Study of Autoimmune Diseases and Medical Dept. B, Sheba Medical Center, Tel Hashomer, and Sackler Faculty of Medicine, Tel Aviv University

We describe an 18-year-old girl with idiopathic thrombocytopenic purpura (ITP) who developed chronic active hepatitis following splenectomy that cured the ITP. This is a phenomenon in which an organ belonging to the immune system is resected, which results in cure of one autoimmune disease but in the emergence of another, apparently unrelated, second autoimmune disease. We refer to this phenomenon as kaleidoscopic autoimmunity, explaining that some autoimmune diseases are not induced by autoantigen-driven mechanisms, but rather result from immune dysregulation.
