סקלרודרמה (טרשת העור) היא מחלה רב-מערכתית מגורם בלתי-ידוע, המתאפיינת בלייפת של העור, ובמעורבות כלי-הדם ואיברים ויסצראליים, כולל ריאות, כליות, לב ומערכת העיכול. באופן גס, מקובל למיין את הסקלרודרמה לשתי קבוצות עיקריות:

1)Diffuse cutaneous scleroderma – מחלה המתאפיינת בהתעבות סימטרית של העור המתהווה במהירות ומופיעה בגפיים, בפנים ובגו. ההתעבות היא בכל הגפיים ולא רק בחלק הרחיקני של הגף. חולים אלה נמצאים בסיכון גבוה ללקות במחלות כיליה ואיברים פנימיים אחרים.

2) Limited cutaneous scleroderma  - מחלה בה קיימת התעבות סימטרית של העור בעיקר בחלק הרחיקני של הגפיים ובפנים. לעיתים קרובות מאובחנים חולים אלה כלוקים בתסמונת CREST (קלצינוזיס, תופעת רנו, ליקוי בתנועתיות הוושט, סקלרודקטילי, וטלאנגיאקטזיה).

לחולים אלה בד"כ פרוגנוזה טובה, ורק מיעוטם ילקו ביתר-לחץ-דם ריאתי או צמקת המרה (biliary cirrhosis).

Angiotropic large B cell lymphoma (angiotropic LCL) or intravascular large cell lymphoma (IVLCL) was diagnosed by liver and bone marrow biopsies and immunohistochemical studies in a 52 year old Caucasian male.

IVLCL is a very rare disease characterized by widespread intravascular proliferation of lymphoma cells. Although it most commonly affects the central nervous system or skin and occasionally bone marrow, angiotropic LCL may be present without evidence of localized disease, as seen initially in our patient.

To date, only a few cases of intravascular malignant lymphomatosis associated with parathyroid hormone related protein (PTH-rP) induced humoral hypercalcemia have been published.

Our extraordinary case was diagnosed mainly by liver biopsy. The neoplastic lymphoid cells stained diffusely and strongly positive with CD-20 (Pan B) and were negative for CD-3 (Pan T) immunostain.

The most significant, initial clinical finding was severe, unexplained hypercalcemia (until 18.6 mg/dl). Plasma PTH-rP showed a ten-fold increase at 8 pmol/L (normal value less than 0.8 pmol/L). Very unusual cytogenic abnormalities were found.

The patient received the massive third generation combination chemotherapy comprising of Methotrexate, Doxorubicine, Cyclophosphamide, Vincristine, Prednisone and Bleomycin and developed, complete although temporary, clinical, humoral and cytogenetic remission.

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.

מחלת לב כלילית מהווה את הגורם העיקרי לתמותה בעולם המערבי בכלל ובאוכלוסיית הקשישים בפרט. באופן כללי, הטיפול הניתן לחולה הקשיש הלוקה בתיסמונת כלילית חדה, הן בשלב החד והן כטיפול ממושך, נרחב פחות ופולשני פחות מזה הניתן לחולה הצעיר ואינו תואם את ההנחיות המקובלות.

חריגויות אלה מבטאות כנראה את תחושת הרופאים, שסיכויי הצלחת הטיפול נמוכים בחולה הקשיש, נוכח מחלות רקע רבות, שכיחות גבוהה של מחלה כלילית רב-כלית, וזמן ממושך יותר, יחסית לצעירים, עד קבלת סיוע רפואי.

המטרות בסקירה זו הן: 1) לבחון את הידוע כיום בספרות אודות טיפול תרופתי ופולשני בחולה הקשיש הלוקה בתיסמונת כלילית חדה; 2) לנסות לענות על השאלה, האם גיל צריך להוות שיקול בגיבוש העמדה הטיפול בתיסמונות כליליות חדות.

Imaging-guided (CT/US) percutaneous biopsy has significantly improved diagnosis of intra-abdominal lymphoma. However, in many cases the tissue retrieved may be inadequate for specialized studies such as immunophenotyping or cytogenetic analysis that may be required for a complete analysis of lymphoma or determination of therapy.

The success of diagnostic laparoscopy in the diagnosis and staging of gastrointestinal malignancies suggests that it could be used for intra-abdominal lymphomas as well. We describe our experience in 15 patients with suspected lymphoma who underwent diagnostic laparoscopy during 1995-98.

Preoperative investigation performed in all included percutaneous FNA in 9 without conclusive diagnosis. Laparoscopy was diagnostic for lymphoma in 14 (93%) while in 1 there was a false negative result due to sampling error and the lymphoma was only diagnosed at a second laparoscopy.

There was no mortality nor any major complication. Average hospital stay was 2 days and patients were then referred for further oncological treatment. Our experience shows that diagnostic laparoscopy is a safe and efficient tool and without major complications in diagnosing abdominal lymphoma.

Presyncope, syncope and falls in undetermined circumstances are frequent among the elderly. They may be caused by orthostatic hypotension secondary to autonomic insufficiency. Tilt-tests and determination of catecholamines in serum and urine may establish the diagnosis, but often may not be feasible in these patients.

A simple, indirect, noninvasive technique to assess autonomic insufficiency is analysis of heart rate variability during Holter-monitoring. We present 5 cases in which it proved useful in the investigation of spells of unconsciousness.
 

Cholesterol Pericarditis Associated with Rheumatoid Arthritis

Dept. of Medicine B, Edith Wolfson Medical Center, Holon; and Sackler Faculty of Medicine, Tel Aviv University

Cholesterol pericarditis (CP) is a rare and unusual disease characterized by chronic pericardial effusion with high cholesterol concentration. Precipitation of cholesterol crystals may occur and induce inflammation and constrictive pericarditis. CP may be idiopathic, but is usually associated with a systemic disease, such as tuberculosis, myxedema, or as in our case, rheumatoid arthritis (RA).

We present a 78-year-old woman with RA, typical deformities of the metacarpo- and metatarso-phalangeal joints and subcutaneous rheumatoid nodules. She was hospitalized with increasing dyspnea and weakness and a 2-dimensional transthoracic echocardiogram showed a large pericardial effusion, without tamponade.

Blood cholesterol was 208 mg/dl, triglycerides 169 mg/dl, LDH 37 u/L and rheumatoid factor 2560 u; glucose, kidney, and thyroid function tests were normal and PPD test negative. Pericardiocentesis yielded 800 ml of opaque, cloudy fluid, with glucose 19 mg/dl, cholesterol 264 mg/dl (normal 20-40 mg/dl), triglycerides 169 mg/dl, LDH 5820 u/L and rheumatoid factor 40 u; viral titers and cultures for bacterial, mycobacterial and fungal infections were negative. The pericardial fluid had a distinctive scintillating, gold-paint appearance and many cholesterol crystals were evident microscopically.

The patient responded to treatment with methotrexate and steroids. Factors responsible for increase in pericardial fluid cholesterol may be its liberation from injured pericardial cells and rheumatoid nodules, lysis of red cells, or lymphatic obstruction and impairment of the absorptive capacity of the pericardium.

Dept. of Medicine C, Assaf Harofeh Medical Center, Zerifin

Anticoagulant treatment for acute myocardial infarction (AMI) and pericardial effusion is controversial, since the treatment might cause hemopericardium and tamponade. On the other hand, anticoagulants are strongly indicated in many situations in AMI, including: left ventricular thrombus, unstable angina, severe heart failure, deep vein thrombophlebitis, pulmonary embolism, atrial fibrillation, as part of thrombolytic treatment, and during cardiac catheterization.

We describe a 70-year-old man who presented with both pericardial effusion and a left ventricular thrombus 3 weeks after an extensive, anterior wall AMI. Anticoagulants and corticosteroids were administered simultaneously under hem-odynamic and echocardiographic monitoring, without complications.

It is our impression that anticoagulant treatment is safe in patients with pericardial effusion.

There has been continuous debate over the superiority of primary percutaneous, transluminal, coronary angioplasty (PTCA) over thrombolysis for acute myocardial infarction (AMI). It was questioned whether this advantage of primary PTCA reported in selected populations by experienced centers can be replicated in our clinical practice.

We compared demographic and clinical variables, therapies and outcome in AMI treated with primary PTCA vs thrombolytic therapy. Clinical and demographic variables of 1,678 unselected AMI patients (admitted January/February and May/July 1996) were analyzed in 16 cardiac care units with on-site catheterization facilities and ability to perform PTCA. Of these 803 (48%) were treated by thrombolysis and 99 (6%) by primary PTCA.

The prevalence of adverse prognostic variables, such as anterior wall MI, heart failure on admission or during hospital stay, pulmonary edema, and ventricular tachycardia or fibrillation, was higher in the PTCA group. The 7-day, 30-day and 1-year mortality rates were similar in the 2 groups: 4%, 7.2% and 12.8%, respectively, in the PTCA group and 5%, 7.2% and 11.1% in the thrombolysis group. There was a trend toward lower mortality in subgroups of high-risk patients: those with heart failure on admission (Killip class >1), the elderly (>65 years), and those with previous MI treated with PTCA. After adjusting for confounders, treatment with primary PTCA was not found to be associated with lower mortality.

Only a small proportion of AMI patients in Israel were treated with primary PTCA in 1996. The frequency of adverse prognostic factors among them was higher but their short and long term outcomes were similar to those of high risk patients treated with thrombolysis.

Concomitant Coronary Artery Bypass Surgery and Pulmonary Lobectomy 

Amit Korach, Uzzi Izhar, Ehud Rudis, Amir Elami

Dept. of Cardiothoracic Surgery, Hadassah University Hospital, Jerusalem

Coronary artery disease amenable to percutaneous interventions or coronary artery bypass grafting, and resectable lung cancer are major causes of morbidity and mortality. We present our experience in the treatment of 3 patients (men aged 64 and 66 and a woman of 77) who each had significant coronary artery disease and a resectable lung tumor. They underwent combined coronary artery bypass grafting and pulmonary lobectomy.

We conclude from our experience and review of the literature that concomitant surgery in such cases is safe and effective, decreases suffering, and decreases the cost of 2 separate invasive procedures.

Preflight Assessment by Hypoxic Inhalation Test in Cardio-Pulmonary Patients

Flying may expose passengers to hypoxic conditions, which may induce hypoxemia, particularly in those with chronic heart and/or lung disease. Onset of dyspnea, wheezing, chest pain, cyanosis and right heart failure can lead to urgent need for oxygen during flight. The hypoxia inhalation test (HIT) provides a safe and simple means of identifying those who may develop hypoxemia during flight.

We report our experience with 48 self-reporting patients who underwent HIT prior to pre-planned air travel. They inhaled for 15-minute periods a reduced oxygen concentration (F₁O₂ 15%) under normobaric conditions, during which O₂ saturation was monitored by pulse oximeter; electrocardiogram, blood pressure and symptoms were also monitored. O₂ saturation of 85% (PaO₂ 50 mm Hg) was considered a positive test. In the 8 cases (17%) with a positive test, 5 had chronic obstructive pulmonary disease and 3 had cardiovascular and/or combined heart-lung disease.

We calculated predicted O₂ partial pressure in altitude (PaO₂ ALT) and compared it to actual results in the 8 patients with a positive HIT. In 5, use of the predicted formula would have under-diagnosed the hypoxemia that developed during the HIT. Thus, the results of the HIT changed treatment strategy in these patients. We recommend that patients with positive tests use O₂ (2LPM or 4LPM) during flight.

HIT is practical and of potential benefit in the objective assessment of patients with various degrees of heart, lung or combined heart-lung disease. Clinicians should be aware of the relative risk of hypoxia during flight in such patients, and of the value of HIT in identifying them, leading to increase in its use.

Unconventional Treatment of Severe Heart Failure in the Elderly

Z. Fidelman, Z. Korshun

Geriatric Medical Center, Natanya

In the elderly, congestive heart failure is common and associated with significant morbidity and mortality.

Comprehensive management of heart failure improves functional status and decreases mortality. Diuretics remain the mainstay in treating congestive heart failure. However, some patients are resistant to diuretics. This is a serious problem as it seems to represent a final manifestation of congestive heart failure.

In an 85-year-old woman diuretic resistance was recognized as the cause of failure of conventional diuretic therapy. When the dose of furosemide was rapidly increased from 120 mg per os to 1000 mg IV within 4 days, diuresis began and there was dramatic improvement in her condition. The dose was then gradually decreased until a conventional maintenance dose of 200 mg/day per os was reached. This dose was sufficient to keep her heart failure under control.

Transient Ischemic ECG Changes in Acute Cholecystitis without History of Ischemic Heart Disease

Lior Lowenstein, Amer Hussein

Dept. of Emergency Medicine, Bnai Zion Medical Center, Bruce Rapport Faculty of Medicine, Haifa

That abdominal distention, nausea, and chest pain may be accompanied by ischemic ECG changes is well known and has been described in the literature. However, very few cases have been reported with acute cholecystitis and ECG changes not due to cardiac ischemia.

We present a previously healthy 20-year-old woman admitted with acute cholecystitis. Prior to surgery routine ECG showed ST-depression and T-wave inversion. The day following cholecystectomy the ECG returned to normal. 1 month later, ergometry and echocardiography were both negative.

Based on the literature and our personal experience, although ECG changes may occur in acute cholecystitis, the possibility of cardiac ischemia must be excluded. However, when no cardiac basis is found, ultrasound of the biliary system might reveal the cause of these ECG changes. Thus, in acute cholecystitis with ischemic ECG changes but no other laboratory or clinical evidence of cardiac ischemia, ECG changes alone are not a contraindication to cholecystectomy. Furthermore, delay in treatment could be harmful.

The efficacy, safety and side-effects of treatment with losartan (Ocsaar) was studied for the first time in Israel in a large group of patients with mild to moderate hypertension in several community clinics. The 421 patients (51% men) aged 30-86 years (mean 58.6) received 50 mg of losartan daily, increased when necessary to 100 mg, and/or a second antihypertensive drug was given. After 4 weeks blood pressure was normalized in 344 and after 12 weeks in 363. Side-effects were minimal and treatment was effective in all age groups.
