בעבודה הקלינית עומדים הרופאים, פעמים רבות, בפני התלבטויות איבחוניות וטיפוליות של חולים במצב קשה, לגביהם האבחנה אינה. וכך, קיימים מצבים בהם לא ניתן לקבוע בוודאות, האם הבסיס למחלה או זיהומי-חיידקי, מחלה זיהומית אחרת (לדוגמה, מחלה נגיפית) או מחלה דלקתית שאינה זיהומית. לדוגמה, בחולה הלוקה במחלה אוטואימונית, לא תמיד ניתן לקבוע האם האבחנה היא התפרצות של המחלה הבסיסית המצריכה טיפול בסטרואידים או בתרופות מדכאות-חיסון, או שהחולה לוקה בזיהום חיידקי חד או באלח-דם המצריכים גישה טיפולית שונה לגמרי (אנטיביוטיקה). באופן דומה ניתן לתאר מצבים נוספים, כמו האבחנה בין דחיית שתל לבין זיהום מישני לצורך הערכת התגובה הדלקתית בחולה שמצבו קשה מבוססים על הערכה קלינית סובייקטיבית ובדיקות דם כגון נוסחת-דם. שקיעת-דם ורמות CRP (C-reactive protein) או ציטוקינים אחרים בנסיוב כדוגמת IL-6 – כולם מדדים בעלי סגוליות נמוכה יחסית. כמו כן, תרביות (דם,שתן, כיח וכד') המהוות מרכיב חיוני לאיבחון זיהומים, מצריכות זמן (בדרך כלל ימים) עד לקבלת תוצאה. בנוסף, תרביות עקרות אינן שוללות תהליך זיהומי (טיפול חלקי באנטיביוטיקה, חיידקים מיוחדים וכד'). מכאן, שקיים צורך במדד מעבדתי זמין מהיר וטוב יותר, שיאפשר איבחון מהיר וגישה טיפולית נכונה.

Infection with Echovirus 11 is mostly asymptomatic, but it may cause a wide variety of clinical diseases, from gastroenteritis to serious diseases such as meningitis and myocarditis. In small infants, especially during the first days of life, echovirus infection may appear as a sepsis-like illness, and cause disseminated intravascular coagulopathy and shock.

We present 2 infants with severe echovirus 11 infections. A 3.5-month old died within 24 hours of shock and probably myocarditis. The other, 6-days old, presented with meningitis, hepatitis and disseminated intravascular coagulopathy. It recovered after treatment with intravenous immunoglobulin.

Echovirus 11 may cause life-threatening infections in small infants. Pediatricians should be alert to the special characteristics of this disease.

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

The adult form of mononucleosis caused by Ebstein-Barr virus (EBV) is different from the disease in children and adolescents. In most adults there is no pharyngitis or lymphadenopathy, fever is much more prolonged, abnormal liver function is frequent and lymphocytosis and the presence of atypical lymphocytes are not common. Such an atypical disease presentation often results in delayed diagnosis and unnecessary treatments. We describe 2 adults with such atypical presentations and complications of EBV infection.

Acquired infection with hepatitis C virus (HCV) in hemodialysis patients has been described lately. In dialysis units in Italy and France, the prevalence and incidence of HCV are 20-60% and 1-2%, respectively. Most infected patients develop chronic hepatitis. The clinical presentation of acute HCV in hemodialysis patients is very mild and therefore the diagnosis is often made only by laboratory tests. Acute infection is usually followed by mild elevation of liver enzymes and the presence of HCV-RNA and anti-HCV in serum.

We report a 48-year-old man on hemodialysis who developed acute hepatitis C. The diagnosis was made by finding mild elevation of liver enzymes and the presence of HCV-RNA in his serum. A few months later, he developed severe hepatitis which was followed by rapid deterioration in liver function. However, the virus was eradicated and liver function tests became normal. Surprisingly, serum anti-HCV antibodies were detected 5 months later.

We conducted a retrospective 5-year survey of corneal infections treated in the ophthalmology ward of Hasharon Hospital. The most frequent type of corneal infection was corneal abscess; the most frequent cause was Staphylococcus albus, although this bacterium is not reported as a frequent cause of corneal infections.

There was improvement in visual acuity in 69.2% and no change in 15.4%. Corneal infection by Pseudomonas aeruginosa was the most frequent cause of worsening of corneal acuity (23.08%). The greatest improvement of visual acuity was in those with corneal ulcers. The worst visual acuity was in those with corneal abscesses. Pseudomonas aeruginosa was the main cause of infection in contact-lens wearers.

In the world medical literature, Staphylococcus albus is considered of very low virulence. This bacterium was the most frequent cause of corneal infections in our study so it may have greater virulence in Israel.

Neisseria meningitidis infection (meningococcemia) is very common throughout the world. It usually presents as meningitis or sometimes pharyngitis. A gastroenteritis-like syndrome, with diarrhea, vomiting and abdominal pain, may occur in children but is very rare in adults. Search of the medical literature revealed only 3 such cases, all in young adults.

We report an 80-year-old woman who presented with fever, diarrhea and abdominal pain. Meningococcus infection was later suspected, and proved by culture. Although treatment was intensive and included ceftriaxone (Rocephin) and garamycin, she did not respond and died 40 hours after admission. We draw attention to the possibility that what is usually a common symptom can be the first presentation of a serious, often fatal condition.

Listeria Monocytogenes Infections - Ten Years' Experience

Tova Rainis, Israel Potasman

Infectious Disease Unit, Bnai Zion Medical Center, and Faculty of Medicine, Technion, Haifa

7 cases of listeriosis were diagnosed here between 1988-1997 (6 in last 3 years), or 2.94/100,000 admissions. 2 elderly patients suffered from meningitis and 2 pregnant women presented with premature contractions, 1 of whom delivered a premature, infected baby. 2 other patients had fever and gastroenteritis.

Listeria monocytogenes was isolated from blood in 4, CSF in 2 and the placenta in 1. It was isolated from those with bacterial meningitis. All patients recovered. Both increased awareness for prevention and better diagnosis are essential to reduce morbidity from this unusual pathogen.

Massive splenomegaly is defined as a spleen weighing about 10 times normal weight. We describe a 36-year-old man who had huge splenomegaly and secondary pancytopenia simulating malignant lymphoma for about 3 months. Splenectomy was necessary because of the suspicion of hematologic malignancy, especially isolated lymphoma of the spleen, and pain and mechanical abdominal disturbances.

On operation, the spleen was 25 cm long and weighed 250 g. There was florid, reactive follicular lymphoid hyperplasia. Immunohistochemical staining with CD-20(L26), CD-45Ro(UCHL), bcl-2 oncoprotein (Dakopatts), EBV (anti-EBV mol weight 60 KD, Dakopatts) was consistent with reaction to EBV infection and not with follicular lymphoma. Lack of PCR amplification using DNA extracted from paraffin-embedded splenic tissue indicated absence of a monoclonal B cell population carrying rearranged immunoglobulin genes. The lymphocytic population was proven polyclonal by the negative results of PCR for the bcl-2 gene rearrangement. EBV seroconversion from high titer antibodies of anti-EBV-VCA-IgM to negative, and from negative EBNA to positive was consistent with an apparent primary EBV infection.

We have not found on computerized search a previous report of reactive follicular splenic hyperplasia to EBV infection causing huge splenomegaly, with or without EBV-induced infectious mononucleosis.

We report acute polyarthritis in an 86-year-old man which was initially considered to be an exacerbation of osteoarthritis. After a delay of a few days a diagnosis of septic polyarthritis as an initial symptom of infective endocarditis was made. Although rheumatic manifestations in infective endocarditis are common, septic polyarthritis is rarely seen. In our patient the course of the disease was rapidly fatal.

Many Faces of Parvovirus

George Habib, Leon Cohen

Carmel Medical Center, Haifa

2 women, aged 31 and 37 years, respectively, suffered from acute febrile illness due to acute infection with human parvovirus B19. 1 also had a maculopapular rash and articular symptoms after her fever stopped, a clinical picture typical of erythema infections. The other had leukopenia and thrombocytopenia and had received dipyrone. Although acute infection with human parvovirus usually occurs in childhood, it may also occur in adults, with protean manifestations.

Is Official Data on Reported Morbidity Valid? Hepatitis A in Israel as an Example

Hepatitis A is one of the most frequently reported notifiable infectious diseases in Israel. The annual incidence as reported is around 70/100,000. The physician or the diagnostic laboratory notifies the district health office of the Ministry of Health.

The purpose of this research was to evaluate the sensitivity of passive surveillance of hepatitis A morbidity among adults, 18 years and over. Methods included study of notifications to the Ministry of Health or hospitalizations of cases of hepatitis A and of positive laboratory tests results (IgM) for hepatitis A. We estimated the extent of under-reporting by 2 different methods of extrapolation.

Data based on passive surveillance among the adult population, between 1.1.1993-31.12.1994, comprised less than 1/5 of the actual number of cases. Physicians notified about 6.2% of their hepatitis A patients. 5.1% of the notifications to the district health office were sent twice or more, usually both by the physicians and labs.

The official data on hepatitis A morbidity, based on passive surveillance, are considerably underestimated. Physicians and public health officials should be aware that such data may not accurately reflect the magnitude of the risk or the amount of disease that can be prevented. Efforts should be made to improve this situation.

Meningitis due to Streptococcus bovis is rare. Only 14 cases having been reported in the English literature. All patients (including the patient described) had an underlying disease or were treated by pharmacological agents that predisposed the patient to the infection. Most were treated by monotherapy with penicillin G (or amoxicillin) and recovered.

We describe a 74-year-old woman who had splenectomy as treatment for hairy cell leukemia 6 months before hospitalization for meningitis and sepsis by S. bovis type 2. She was successfully treated with intravenous amoxicillin. There was neither evidence of endocarditis nor carcinoma of the colon. Although the association between S. bovis meningitis and endocarditis or carcinoma of the gastrointestinal tract is not well established, we recommend a full work-up for GI malignancy and endocarditis in every patient with S. bovis meningitis.

A 42-year-old man was admitted for fever and severe low back pain radiating to both legs. On MRI, an epidural spinal abscess from S1 to D10 was seen. Treatment included laminectomy, drainage of the abscess and antibiotics. Recovery was complete without neurological damage. Increased awareness of this disease may lead to diagnosis and treatment.

Laparoscopic cholecystectomy is the "gold standard" in treating cholelithiasis. Stones are frequently lost in the peritoneal cavity during the procedure, but "missing stones" have been regarded as insignificant. However, there is accumulating evidence that untreated "lost" stones may cause complications even years after operation.

We present a 65-year-old woman who presented with vague complaints, anemia and an elevated ESR. CT scan showed an infiltrating process in extra-abdominal muscles compatible with sarcoma. At operation, 2.5 years after previous laparoscopic cholecystectomy, an abscess was found which contained biliary stones. Because of their small size they were not visible on CT scan. We discuss the possible ways of handling "falling stones."

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.
