באוכלוסייה בישראל, כמו בשאר החברות המפותחות, המחסור הקליני ברכיבי קורט (micronutrients), כלומר, ויטמינים ויסודות קורט (microelements), אינו שכיח. עם זאת, תת-אוכלוסיות מסוימות מצויות בסיכון לחסרים קליניים ותת-קליניים. קשישים מצויים בסיכון גבוה מצעירים למחסורים שונים, בעיקר בתקופות עקה או טיפול בבעיות בריאותיות. צריכה ירודה של מזון עלולה להיות תוצאה של ירידה בתיפקודי האיברים השונים ושל בעיות חברתיות ונפשיות, העלולות להשפיע על התיאבון והספיגה או על היכולת לרכוש, להכין ולצרוך מספיק מזון. בעיות אלה כוללות, בין השאר, הפרעות בבריאות השיניים ובלעיסה, הכנסה בלתי-מספקת (על-מנת לרכוש מזונות מתאימים) ונטילת תרופות. עם הגיל, בשל ירידה במסת הגוף הכחוש, חלה ירידה בצריכת האנרגיה וכתוצאה ירידה בצריכת רכיבי תזונה (רכיבי תזונה עיקריים ורכיבי קורט). עקב שינויים במערכת העיכול (ירידה בהפרשה של חומצת מלח, בשטח הספיגה, בתנועתיות הקיבה והמעיים ובאספקת הדם), חלה ירידה בספיגה. צריכת התרופות בקרב קשישים היא גבוהה, וחלק מתרופות אלה נוגד את פעולתם של כמה מהויטמינים. קיימים פירסומים וקובצי נתונים המעידים על צריכה לא מספקת של רכיבי הקורט במזונם של קשישים. אולם המידע המצוי מועט ביחס לחשיבות הנושא.

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.

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.

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.

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.

Resection presents the only possible cure for pancreatic cancer. An aggressive surgical approach may extend the limits of resection and offer cure for more patients. 37 women and 28 men, mean age 67 years (range 33-84) with focal lesions underwent pancreatic resection (1993-1999). Cancer of the pancreatic head was found in 45, in the ampulla in 4 and in the body or tail in 16. There was a tumor larger than 5 cm in 9, vascular involvement in 8, and a combination of both in 6.

All were evaluated prior to exploration by standard imaging techniques and 44 by laparoscopic ultrasound. 42 underwent pancreatico-duodenectomy, 16 distal subtotal pancreatectomy and 3 local excision of an ampullary tumor. Benign lesions were found in 8 (focal pancreatitis in 4 and a serous cystic lesion in 4).

Curative resection (microscopically negative margins, negative lymph nodes) was achieved in 44. 2 died 1-2 months after operation of septic complications (2% operative mortality). The most frequent complication (in 8) was pancreatic fistula. Additional complications included anastomotic-line bleeding (3), intra-abdominal abscess (2), and 1 developed portal vein thrombosis (treated surgically).

1- and 2-year survival in those after curative pancreatic resection was 81% and 55% respectively. 2-year survival in those after palliative resection (positive resection margins or positive lymph nodes) was 50% and 11%, respectively.

After proper selection of those in whom it is possible to perform curative resection, regardless of size or vascular involvement, an aggressive surgical approach is justified.

Spina bifida and anencephaly are the most common, serious malformations in neural tube defects (NTD). Randomized trials in the last 2 decades have demonstrated that folic acid, 0.4 mg/d, reduces the incidence of NTD by more than 50%. We investigated the use of folic acid and multivitamins containing folic acid in childbearing women.

Of 221 women interviewed, 67 (30%) regularly took pills containing 0.4 mg folic acid. Women with higher educational levels were more likely to take multivitamins with folic acid than were the less educated (p=0.05). Of the women who took folic acid, only 5 (7.5%) used separate folic acid tablets, before and during their pregnancy. The rest used multivitamins containing folic acid. The 5 women who took folic acid separately were college-educated and nonreligious, and they took multivitamins in addition (p>0.05).

Of the women interviewed, 58 (26.2%) were Bedouin of the Negev. 24 (41.4%) of them took pills containing folic acid on a regular basis. This percentage is higher than that in the Jewish women in the study who took folic acid for prevention of NTD (17%; p=0.038).

Most of the women took folic acid after the first trimester. Only a minority took daily periconceptional folic acid. Multivitamins containing 0.4 mg of folic acid were more popular than folic acid tablets alone. This study emphasizes the need for continuing efforts to increase consumption of folic acid and awareness of its benefits among women of childbearing age.

Results of reconstruction of residual alveolar bone defects in 52 patients operated between 1990-1998 were evaluated clinically and radiographically in a retrospective study.

Ages ranged between 9-37; 30 were males. The donor site of bone grafts in all was particulate cancellous marrow from the anterior iliac crest. 32 had unilateral clefts and 20 bilateral. Total cleft sites treated was 72.

Best results were achieved when bone grafting was carried out prior to the eruption of the canine tooth. The cleft space was closed and oro-nasal fistulas were eliminated in 42 (80%). Success rates in unilateral and bilateral cases were significantly different.

Anticoagulant Treatment in Pericardial Effusion - A Therapeutic Dilemma

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.

Cholangiocarcinoma accounts for about 1% of all malignant tumors. They are difficult to diagnose because of their small size and their location. Although surgical resection is the best therapeutic approach, most patients undergo unnecessary exploratory laparotomy due to incorrect preoperative diagnosis.

We present our experience with laparoscopic ultrasound (LU) in the evaluation of cholangiocarcinoma and determination of tumor spread and vascular involvement. Of 25 patients referred for surgery, 6 were excluded following LU and were referred instead for palliative treatment. Diagnosis of the tumor was successful in 92%, and vascular involvement was diagnosed in 46%. LU should be an integral diagnostic test in the evaluation of choriocarcinoma.

Laparoscopic Approach in Treating Hepatic Cysts

Dept. of Surgery A, Wolfson Medical Center, Holon

Solitary and multiple hepatic cysts are now more commonly found because of advances in imaging techniques. Most hepatic cysts are asymptomatic, but when they do cause symptoms they require surgical intervention. The advent of laparoscopy and of laparoscopic ultrasonography allow comprehensive evaluation and treatment of the cysts.

12 patients with hepatic cysts were treated laparoscopically. 8 with single cysts underwent successful subtotal cyst resection without signs of recurrence (up to 20 years of follow-up). 4 with polycystic liver disease underwent sub-total resection of superficial cysts. Deep cysts were unroofed and drained under laparoscopic ultrasound guidance. In this group, 1 experienced recurrence of symptoms and required partial hepatectomy of the involved segment. In another, a connection between a deep cyst and bile ducts was demonstrated and cystojejunostomy was performed.

The laparoscopic approach in the management of patients with liver cysts is effective and safe, and we recommend it as the procedure of choice for single hepatic cysts. In polycystic liver disease the procedure is much less successful.

Cortical blindness has been occasionally reported as a complication after cerebral angiography, but is rare after coronary angiography. The contrast agent is believed to be responsible for the sudden development of blindness. Although the exact mechanism is unknown, it appears that the contrast agent disrupts the blood brain barrier, mostly in the occipital areas.

We report a 77-year-old man who suddenly developed transient, bilateral cortical blindness 4 hours after coronary angiography. Using contrast enhancement, the CT scan showed typical, symmetrical involvement of both occipital lobes. There were no other neurological deficits. Vision and CT findings returned to normal within 48 hours.

We compared traditional local excision of hemorrhoids in 40 patients (group A) with excision using the CDH-33 surgical stapler designed for bowel anastomosis, in 41 (group B). In this technique a purse-string suture is prepared 3 cm above the dentate line, and the stapler is inserted and used to form a mucosa-mucosal anastomosis. This technique is less time-consuming than the traditional technique.

Data were collected from patients' medical files and from detailed questionnaires in which symptoms prior to and after operation were reported. Mean ages were 53.0 and 51.5 years and male/female ratios were 1.0:1.2 and 1.0:1.1 respectively, neither significant. The most common complaints in both groups were pain and rectal bleeding. All patients had a lower-GI investigation prior to operation to exclude other causes of rectal bleeding.

Recovery averaged 2 months in both groups. Patient satisfaction was assessed by decrease or absence of symptoms on return to normal daily activities. Satisfaction tended to be greater in group B. More patients in group A complained of tightness and discomfort at the operative site, but this was not significant.

We are extending our study to a larger number of patients to determine if there are statistically significant differences between the results of the 2 methods.
