The use of an endoscopic, minimally invasive technique for the removal of salivary gland stones from the submandibular or parotid duct is described. A 2.0-2.7 mm endoscope is inserted into an incision in the parotid or submandibular duct. When the stone is visualized through the endoscope it is removed using suction and forceps. We used this technique in 45 cases for removal of calculi, screening the ductal system to rule out residual calculi. and determination of ductal dilatation. The success rate was 80% and there were no major postoperative complications. To the best of our knowledge these are the first such cases reported in Israel.

Over a 24-year period, 62 infants (47 girls) with hemangiomas were treated with an initial dose of either 3 or 5 mg/kg/day of oral prednisone for 2 weeks, after which the dose was gradually tapered off during 6-8 weeks. Few patients required longer treatment. Results were judged to be excellent in 68% of infants and good in 25%. Treatment was considered a failure in only 7%. The initial dose of 5 mg/kg/day was more effective than the smaller dose (p<0.001). Of the 62 patients, 49 received 1 course of treatment, 8 required 2 courses and 5 required 3 courses. Retreatment was given whenever significant regrowth occurred. Side-effects were not serious, and resolved when treatment was discontinued. Treatment was indicated when the location of the lesions caused interference with important functions or when the lesions were likely to damage anatomic structures. Special attention was paid to early treatment of eye and subglottic hemangiomas. In all 22 children with hemangiomas of the eye (most with an orbital component), shrinkage of the lesion was observed within 24 hours of initiating treatment. In 19 of the 22 there was no residual of the hemangioma 1-18 years later. Such lesions deserve early treatment, not just as cosmetic emergencies, but to prevent secondary amblyopia. Early treatment of subglottic hemangiomas is also mandatory because they are potentially life- threatening. We conclude that oral prednisone is very effective in the treatment of hemangiomas of infants when given at a high dose for an adequate period of time.

With limited organ resources and an increasing number of candidates for liver transplantation, the world-wide trend is towards using liver allografts from donors older than 60 years. This strategy, however, may be hazardous because of the known correlation between advanced donor age and graft dysfunction. Since January 1996, each of 5 patients received a liver allograft from a donor older than 60 years. Preservation time in these cases was shortened as much as possible and liver allografts were used only if there were no other potential risk factors for primary nonfunction. Mean cold ischemic time was significantly shorter in this donor group (7.8 hrs) than for livers from 28 younger donors (10.2 hour; p<0.01). 3 of the 5 grafts from older donors had normal function immediately. The other 2 initially had biochemical features of preservation injury, but graft function returned to normal within the first week after transplantation. All 5 patients currently have normal graft function, with follow-up ranging from 3-8 months. There was no difference between the 5 recipients of grafts from older donors and 28 adult recipients of grafts from younger donors in extent of preservation injury and in immediate graft function. We conclude that in countries with limited organ resources, such as Israel, liver allografts from older donors can be used within defined limits and minimal preservation time.

Attention-deficit hyperactivity disorder (ADHD) has been considered a mental and behavioral disorder of childhood and adolescence. It is being increasingly recognized in adults, who may have psychiatric co-morbidity with secondary depression, or a tendency to drug and alcohol abuse. We describe a 32-year-old woman known for years as suffering from borderline personality disorder and drug dependence (including hasshish, marijuana, LSD and "exstasy'") and alcohol abuse that did not respond to treatment. Only when correctly diagnosed as ADHD and appropriately treated with the psychotropic stimulant, methylphenidate (Ritalin), was there significant improvement. She succeeded academically, which had not been possible previously, the craving for drugs diminished and a drug-free state was reached. Although administration of psychostimulants to drug abusers is controversial, as they are addictive, in cases of ADHD they have promoted drug abstinence.

Na+/H+ exchange (NHE) was measured as maximal initial velocity of pH-dependent H+ efflux from red cells into an alkaline medium containing Na+ in patients with insulin-dependent or noninsulin-dependent diabetes, with and without hypertension and in normoglycemic, essential hypertensives and normal controls (50 subjects in each subgroup). Maximal velocities of NHE were found in microalbuminuric patients in all subgroups, and NHE correlated with the rate of microalbuminuria (r=0.61, p=0.02). Daily insulin requirements were greater in those with elevated NHE (84±8 vs 42±4 U/day). There was no correlation between NHE and levels of plasma glucose, HbA1 and plasma aldosterone and lipid profile and PRA. NHE was correlated with plasma prolactin (r=0.51, p=0.02) and PTH r=0.24, p=0.05). In uremic patients, NHE was inversively correlated with creatinine clearance (r=-0.48, p=0.03). Since calphostin C, a selective inhibitor of protein kinase C, lowered increased NHE in vitro, the protein kinase C-dependent pathway of the exchanger regulation was concluded to be responsible for NHE activation in diabetes mellitus and essential hypertension.

The need for solid organ retransplantation is a major factor in the shortage of available organs. Between 1972 and 1992, 56 out of 309 kidney transplants and 2 out of 20 liver transplants performed in our hospital were retransplantations. The present study evaluates local and world experience with organ retransplantations in terms of the medical and ethical issues.

In the past 20 years Hickman catheters have gained increasing acceptance for many uses, including bone marrow transplantation, long-term chemotherapy, total parenteral nutrition, dialysis, and administration of antibiotics and fluids. Until the past decade these catheters were inserted in the operating room. We present our experience in the percutaneous placement of 203 Hickman catheters in an interventional radiology suite in 190 consecutive patients within a period of 30 months. Catheter placement was successful in 202 (99.5%). The main complications were infections, necessitating removal of the catheter in 11 cases (5.4%) and unintentional dislodgement of the catheter in 8 (3.9%) - all in women and most on the right side. Pneumothorax and thrombosis in the catheter each occurred once. In another patient the guide wire broke during insertion and had to be percutaneously removed from the pulmonary artery. Late fracture of the catheter occurred in 2 others in whom the intravascular fragment was removed percutaneously. We believe that percutaneous Hickman catheter placement in the radiology suite offers advantages over traditional surgical placement.

In recent years there have been numerous reports of successful treatment of resistant ulcerative colitis with cyclosporin. A series of 9 patients with moderate to severe active ulcerative colitis was treated with cyclosporin between September 1993 and October 1994. All 9 had failed to respond to conventional therapy, including salazopyrine and intravenous corticosteroids. They underwent colonoscopy and after contraindications to therapy were ruled out, received intravenous cyclosporin, 4 mg/kg/day for 7-10 days. They were discharged on oral cyclosporin with average serum levels maintained at 200 ng/ml. Response was assessed using the clinical score system of Schroeder et al. 2 out of 9 patients (22%) responded with full clinical remissions lasting more than 6 months. 6 patients had partial responses to the intravenous therapy, but symptoms resumed shortly after its cessation. Factors predicting favorable response to cyclosporin therapy were a shorter duration of disease with a fulminant clinical course. The success rate was less than that reported in the literature, possibly because of comparatively low serum cyclosporin levels. Potential complications of therapy and high cost preclude the routine use of cyclosporin in ulcerative colitis. Larger controlled studies are required to assess its efficacy and safety. Until such studies are available, cyclosporin may be tried in poor surgical risks or those not yet ready psychologically for total colectomy.
