Surgery remains the only curative approach to cholangiocarcinoma. Despite operative difficulties concerning tumor location, vascular involvement or hepatic invasion curative resection (i.e. achievement of tumor free margins) carries good survival rates and is associated with low morbidity and mortality. Our experience with 31 patients with cholangiocarcinoma operated during the years 1993-1999 is presented.

Twenty-five patients were found to have hilar cholangiocarcinoma, 3 carcinoma of mid-choledochus and 3 distal cholangiocarcinoma. All patients were evaluated by a diagnostic protocol including laparoscopy and laparoscopic ultrasound. Surgery consisted of local resection of the tumor with Roux en Y hepaticojejunostomy reconstruction. Three patients had concomitant hepatic resection for hilar cholangiocarcinoma while 3 patients had pancreaticoduodenectomy for distal cholangiocarcinoma. Adenocarcinoma was diagnosed in all patients. Curative resection was achieved in 19 patients and palliative resection (microscopically involved resected margins) in 12. One patient died at 60 days postop (3.5% mortality). Postoperative complications included cholangitis occuring in 10 patients who were referred with biliary drains, intraabdominal abscess (2 patients) and biliary leakage (1 patient) all treated conservatively.

Overall survival rate was 82% at one year, 73% at two years and 45% at 5 years. When comparing curative resection with palliative resection, survival rates were 92% versus 71% for 1 year, 72% versus 50% for 2 year and 57% versus 14% for 5 years.

Selection of patients using Laparoscopic Ultrasound combined with aggressive surgical approach enable curative or palliative resection 15 the only treatment modality which is significantly improved survival.

Stealing Madness - Kleptomania

Dana M. Polak, Pinhas N. Dannon

Psychiatry Department C, Sheba Medical Center Tel Hashomer, Israel

Kleptomania is one of the common less diagnosed impulse control disorders, which could be treated by the combination of psychological and pharmacological therapy. The most effective treatment regimens include cognitive behavioral therapy and interpersonal psychotherapy in the psychological field, and antidepressants and mood stabilizers as pharmacological treatment.

Most of the patients with kleptomania are initially treated only for a comorbid psychiatric disorder, since kleptomaniac symptoms had not been raised in the anamnesis.

The aim of our article is to inform the physicians about the possible diagnosis and treatment options for this disorder in order to prevent co-morbidity with other psychiatric disorders. Some specific cases are presented in order to explain symptomatology.

Introduction: Sentinel lymph node biopsy (SLNB) has been recently proven to be an accurate staging method for breast cancer, replacing axillary lymph node dissection (ALND) in selected cases. We present our initial experience and the process of introduction and implementation of SLNB in a University Hospital setting.

Material and methods: 46 SLNB were performed in 42 consecutive female patients with invasive breast cancer. Treatment included 0.4mCi-2mCi of Tc-99m rhenium colloid injected either 2 hours before surgery (0.4 mCi) or the night before surgery (2 mCi). Four milliliters of Patent Blue V were injected peritumoral 10 minutes prior to skin incision in all patients. Following SLNB all women underwent subsequent ALND. Sentinel nodes were processed both with multiple (10-15) H&E sections and immunohistochemistry with cytokeratin antibodies stain.

Results: Blue dye, isotope or the combination of both identified 43/46 (93%) of the sentinel lymph nodes. ALND was performed only unilaterally in 4 patients with bilateral breast cancer bringing the total evaluable SLNB to 39. In the 39 patients in whom the sentinel node was successfully identified and underwent ALND, the SLNB was true positive (TP) in 17/39 (44%) true negative (TN) in 20/39 (51%) and false negative in 2/39 [(5%), both T2 lesions] with overall accuracy of 95%. In the last 10 cases all sentinel nodes were successfully identified with 70% TP and 30% TN.

Conclusions: Experience with at least 30-40 consecutive cases for safe implementation of SLNB in clinical practice. Specific training and dedication is required for the entire team involved, including surgeons, nuclear medicine physicians and technicians and pathologists.

Terbutaline sulfate (Bricalin) is a widely used medication for asthma. It works mostly, but not only, on beta-adrenergic receptors.

In this case study we describe a 50-year-old nurse referred to the emergency department after she was stabbed by needle that was used to draw bricalin for inhalation. She arrived at the emergency room with an inflamed necrotic area at the point of the stab. Later, she developed acute infection that was treated with antibiotics. Following the acute phase there was still a necrotic area, that required surgical debridement.

It seems that this is the result of the vasoconstrictive influence of terbutaline sulfate via alpha adrenergic receptors. In the medical literature there is scarce data regarding this side effect.

Graves' ophthalmopathy is an autoimmune disease manifested as exophthalmus, lid lag and diplopia. As in the accompanying autoimmune thyroid disease, there is an autoimmune homoral and cellular attack on the orbita, mainly the retro-orbital tissues.

Steroids are the comerstone of therapy. We reviewed the evidence for a similar therapeutic effect of I.V., immunoglobulins (IVIGs) and their better side affect profile as compared to steroids. We also described an impressive therapeutic success with IVIG given to a patient with resistant ophthalmopathy. The clinical picture of Graves' ophthalmopathy is attributed to a pathologic hyper - activation of orbital fibroblasts, deposition of collagen and glycosaminoglycans in the extra-cellular matrix and eventually fibrosis. These are mediated by leucoregulin, IL-1, IFN-gamma, and TGF-beta - all secreted by lymphocytes and mast cells in the retorbital space.

Another mode of cell activation is by binding of autoantibodies (presumably thyroid stimulating Ab's) to an antigenic determinant on the surface of fibroblasts.

I.V. immunoglobulins, known today to be active in a variety of autoimmune processes, exert their effect on autoantibodies, complement, phagocytic cells etc. IVIGs also inhibit orbital lymphocytes and fibroblasts through inhibition of IL-1 or/and TGF-beta.

Background: Traumatic Brain Injury (TBI) has been established as a category in reporting systems. Uniform data systems case definition has been suggested for hospital discharge data surveillance systems cases based on ICD-9-CM diagnostic codes. These include fractures and specific mention of intracranial injuries such as contusion, laceration, hemorrhage, and concussion. Inspection of data from the Israel National Trauma Registry suggested that two diagnostic groups of very different severity and outcome were being unjustifiably combined.

Aim: To evaluate the validity of categorizing TBI into two discrete groups, using the presence of specific mention of intracranial injury and/or loss of consciousness for more than one hour as the definition of definite TBI. Possible TBI includes skull fractures with no mention of intracranial injury and/or concussion with no loss of consciousness.

Methods: The study population includes all traumatic injuries admitted to hospital, dying in the ER or transferred to other hospitals and recorded in the 1998 Trauma Registry in all 6 level I trauma centers in Israel and two level II centers.

Results: The significant difference in severity between groups supports the validity of sub-dividing the TBI classification into definite and possible subcategories. As a result, we obtain two different severity groups without measuring specific severity scores which are limited in the reporting system.

Conclusion: The groups were significantly different in severity, hospital resource use, immediate outcome, demographic and injury circumstances.

Background: Minor depression is reported in 20-60% of schizophrenic patients during various stages of their disorders; impairing patients' compliance, response to treatment and worsening their overall prognosis. Various anti-depressive treatments have been proposed for such cases but response rates are usually poor. Pyridoxine (Vitamin B⁶) in essential for the proper metabolism of various neurotransmitters that are considered relevant to the pathophysiology of depression and/or schizophrenia and it has been reported beneficial in ameliorating depressive symptoms as part of major depression, premenstrual syndrome or 'Chinese restaurant syndrome'. We hypothesized that addition of pyridoxine to on-going neuroleptic treatment could improve minor depression in schizophrenic patients.

Method: Nine schizophrenic patients with co-morbid minor depression participated in this study. All participants had a stable unchanged clinical state (changes in Brief Psychiatric Rating Scale (BPRS). Scale for the Assessment of Positive Symptoms (SAPS), and Scale for the Assessment of Negative symptoms (SANS) scores <5%) and all were maintained on unchanged doses of anti-psychotic drugs for at least 4 consecutive weeks prior to initiation of the study.

Participants received, open-label, pyridoxine 150 mg/day in addition to their anti-psychotic treatment for 4 consecutive weeks. Mental status was evaluated before, during, and at the end of 4 weeks of pyridoxine administration using the BPRS, SAPS, SANS and HAM-D.

Results: Two of the nine patients (22%), characterized by higher initial HAM-D and SANS scores, and by older age and longer duration of illness, experienced marked improvements in depressive symptoms (23% and 28% decrease in HAM-D scores) following 4 weeks of pyridoxine administration. In one of these two, the improvement in depressive symptoms was accompanied by a parallel decrease in SANS Scores.

Conclusion: A subgroup of schizophrenic patients with co-morbid minor depression may benefit from pyridoxine addition to their on-going anti-psychotic treatment.

מדי שנה, כ-40% מכלל המעשנים מנסים, או לפחות מצהירים על רצונם להיגמל מעישון, אך רק כ-6% מתוכם אכן מצליחים במשימה זו לטווח ארוך. גם שיטות הגמילה עם תחליפי-הניקוטין, כגון טבליות הלעיסה או הדיסקיות המוצמדות לעור, העלו את שיעור הנגמלים פי 1.4 עד 2.6 בהשוואה לנוטלי האינבו, אך 80%-70% מבין אלה שחדלו לעשן באמצעות תחליפי-ניקוטין, חזרו תוך שנתיים לשיגרת העישון.

ניסויים לגמילה מעישון באמצעות תרופות נוגדות-דיכאון נמצאים לאחרונה בקו-עלייה. כך לדוגמה, התכשיר nortriptyline התלת-ציקלי, נמצא מכפיל את שיעורי הגמילה, ותוצאות מבטיחות התקבלו עם doxepin ו-fluoxtein. ייתכן, שההצלחה היחסית של נוגדי-דיכאון בגמילה מעישון, מקורה בקשר הגורדי בין דיכאוניות ועישון: מעשנים עם רקע דיכאוני תלויים יותר בניקוטין והצלחתם בגמילה פחותה, שכן דיכאון הוא אחד מתסמיני הגמילה הבולטים אצלם. עישון סיגריות מביא גם כן להפחתת פעילות האנזים monoamine oxidase B במוח במנגנון שאינו שאינו קשור לניקוטין, ובכך משתמרת יותר רמת הדופאמין, בעלת השלכות נוגדות-דיכאון.

Between 1972 and 1994, 121 adult patients with advanced Hodgkin's disease received MOPP (M) combination chemotherapy, MOPP alternating with ABVD (M-A) or MOPP and ABV hybrid (M/A). Radiation therapy was given to 1/3 of them. The median age was 35 years, 58% had stage III and 42% had stage IV disease. Failure-free survival at 10 years was 43.9%. It was 66.7%, 48.4% and 29.9% for patients treated by M/A, M-A and M, respectively. Overall survival at 10 years was 40.8%, and 78.2%, 48% and 27.7% for patients treated by M/A, M-A and M, respectively. Multivariate analysis found age (above or below 65 years) and combination chemotherapy (with or without adriamycin) to be significant prognostic factors. M/A combination was more myelotoxic, while M combination caused more second primaries. Today, 80% of patients with advanced Hodgkin's disease may be cured, with low rate of long-term toxicity.

Streptococcus pneumoniae is an important cause of pediatric morbidity and its main reservoir is the nasopharynx, from which it can disseminate and cause invasive disease. From November 1997 through March 1998, nasopharyngeal carriage of S. pneumoniae was evaluated in 250 children under the age of 36 months: 123 Jews and 127 Bedouins with acute respiratory disease and in 980 healthy control children (852 Jews and 128 Bedouins).

Carriage rate was higher among sick children. Among Jewish children it was 57% and 35% of sick and healthy children respectively (p<0.01), and among Bedouin children it figured as 80% and 67% respectively (p=0.01). The difference in carriage rate was most prominent in infants under the age of 5 months: among Jewish children it was 60% and 27% of sick and healthy children respectively (p<0.001) and among Bedouins it was 82% and 65% respectively (p=0.05).

Higher carriage rate of penicillin resistant pneumococci (PRP) was also detected in sick children, with no relation to antibiotic treatment in the month prior to sampling. In Jewish children PRP was detected in 12%, 28% (p<0.001) and 36% (p<0.001) of healthy children, sick children with previous antibiotic treatment and sick children with no treatment, respectively.

The seroypes included in the newly developed 7-valent conjugate vaccine: 4, 6B, 9V, 14, 18C, 19F, 23F, that are highly pathogenic and often antibiotic resistant contributed 74% of isolates in sick Jewish children who had previous antibiotic treatment and 39% of isolates in healthy children (p<0.001). In Bedouin children vaccine types carriers rate among the sick children was not higher than in healthy children.

Acute respiratory disease increases the risk of pneumococcal carriage in general and carriage of resistant pneumococci in particular. Previous antibiotic treatment increases the risk of carring one of the pathogenic serotypes included in the 7-valent vaccine. The impact of disease is most prominent in infants under 5 months, since they are usually less exposed to S. pneumoniae carriers than older children.

Since the increase in carriage rate during illness is mostly due to the serotypes included in the newly developed conjugate vaccine, future immunization programme may decrease not only morbidity rate but also nasopharyngeal carriage rate of pneumococci in general and of antibiotic-resistant pneumococci in particular.

חשיבות המערכת הוורידית והחזר הדם ללב האדם הבוגר ידועה זה שנים. למעשה, השליטה העיקרית בתפוקת הלב הבוגר נקבעת על פי שינויים בזרימה ובהחזר הוורידיים. מדידות לחצים וזרימות במערכת ההחזר הוורידי ללב, משמשים כלי ניטור יומיומי ביחידות לטיפול נמרץ וטיפולים תרופתיים רבים מיועדים לשיפור זרימה זו במצבי אי-ספיקת לב. עם זאת, הזרימה העוברית וההחזר הוורידי ללב העובר לא נחקרו עד לשנים האחרונות. הסיבה לכך כפולה. ראשית, דגם עובר הכבש לבדיקת זרימת הדם שפותח בשנות השישים ייצג בעיקר, את המערכת העורקית. שנית, זיהוי מדויק של מערכת הזרימה הוורידית קשה יותר טכנית ורק עם פיתוח שיטת דופלר בצבע, ניתן היה להדגים ולמדוד בוודאות את צורת גלי הזרימה של מרכיבי המערכת ולדגום אותם. התפתחות נוספת בשנים האחרונות נובעת מהדגמה מדויקת יותר של המערכת ומאפשרת מדידת זרימת הדם במונחי מ"ל/דקה.
