האירגון האמריקאי לסוכרת (The American Diabetes Association - ADA) – ממליץ, שאם לא הושג איזון של הסוכרת בחולים NIDDM תוך שלושה חודשים על ידי תזונה דלת-סוכר והתעמלות, יש להתחיל בטיפול תרופתי. בדרך כלל מומלץ להתחיל בתרופה פומית אחת המורידה את רמת הסוכר, כמו, לדוגמה, (s‘SLP) sulfonylureas, (MTF) metformin, (ACS) acarbose או אינסולין.

בבחירת התרופה, יש לדעת את הפתוגנזה העיקרית שהביאה להיפרגליקצמיה, מנגנון הפעולה של התרופה, מחירה, השפעות-הלוואי, אופן מתן התרופה ומידת הדחיפות להורדת רמת הסוכר, דהיינו, ההסתמנות הקלינית של החולה.

התרופות מקבוצת ה- sulfonylureas הן השימושיות ביותר היום כטיפול התחלתי. Metformin מקבוצת ה- biguanides הוא תרופה מהקו הראשון לטיפול בחולי NIDDM הלוקים בהשמנת-יתר ועמידות לאינסולין. התרופה יעילה במיוחד במישלב עם תרופה מקבוצת ה- sulfonylureas, במיוחד במצבים בהם ה- s‘SLP בלבד לא הביאו לאיזון החולה.

התרופה החדשה יחסית acarbose מקבוצת האלפא glucosidase מפחיתה בצורה ברירנית את עליית הגלוקוזה לאחר הארוחה, ואין לה כמעט השפעה על רמת הסוכר בצום. שתי הקבוצות שהוכנסו לשימוש רק לאחרונה הן:

קבוצת ה- thiazolidinedione (troglitazon, rosigltazon) מגבירה את רגישות הרקמות ההיקפיות לאינסולין, כלומר, "מעוררת" תגובה חזקה יותר לאינסולין בשריר, בריקמת השומן ובכבד.

קבוצת ה- meglitinides (repagilinide) מגבירה את הפרשת האינסולין מהלבלב בדומה לקב' ה- s‘SLP, אלא שהשפעתה מהירה יותר וקצרה יותר, ומתאימה להפחתת רמות הגלוקוזה בנסיוב לאחר ארוחה.

Medical Division, Hadassah Hospital, Ein Kerem, Jerusalem

Pneumomediastinum is termed spontaneous when not associated with trauma or other identifiable pathological process. There are several reports of pneumomediastinum following narcotic drug inhalation or smoking while applying positive pressure. We describe a 37-year-old male drug addict, hospitalized after having being found unconscious with shortness of breath. CT scan demonstrated bilateral pneumonia with pneumomediastinum. After a day of mechanical ventilation he gradually recovered and the mediastinal air disappeared.

Pneumomediastinum may occur in addicts but usually has no dangerous clinical consequences. If there is respiratory deterioration another cause should be sought.

Oral rehydration (OR) for acute gastroenteritis in infants and children has been shown to be as effective as IV therapy, with less discomfort and lower costs. In this retrospective study we compared 2 pediatric wards, in 1 of which only a standardized, simplified, bedside protocol, based on American Academy of Pediatrics guidelines, was used.

There were no significant clinical characteristics in the 208 patients. In the ward which used the above protocol, OR utilization was significantly more frequent than in the other ward (48% versus 15%), thus saving equipment costs of nearly $1,000/3 months. There were no significant differences in outcome between the wards.

We conclude that introducing a standardized management protocol may increase OR utilization in hospitalized children with acute diarrhea.

Institute of Halachic and Ethical Aspects of Medicine, Ramat Gan

The ability to fertilize human ova with sperm retrieved soon after death has been utilized in Israel and in other countries. However, postmortem sperm procurement (PMSP) has significant Halachic, juridical and ethical implications with regard to both the action of sperm and its implications for mother and offspring. In specific situations, and with reliable supervision aimed at preventing sperm interchange, Halacha may allow the procedure, while the juridical approach in such a situation is not as yet well established.

As for Halacha, even if a son is born, the widowed mother will still be obligated by the Halacha of yibum (marrying the deceased husband's brother). The child's rights as heir, aspects of implications for its future life, or even social aspects of PMSP, all are factors to be seriously considered before PMSP is performed, without bias by temporary emotions. Thus, PMSP should be reserved for only very special circumstances, and only after consultation with the appropriate medical, Halachic, juridical and ethical experts.

Dermatitis from Contact with Agave Americana

Dermatology Dept., Tel Aviv-Sourasky Medical Center

Various plants induce dermatitis in man. There have been only a few published cases of contact dermatitis caused by Agave americana (AA).

We report intentional exposure to AA in a soldier seeking sick leave, and review our previously reported cases. Treatment with oral antihistamines and topical saline compresses resulted in subsidence of the systemic symptoms within 24h and regression of cutaneous manifestations in 7-10 days.

Physicians should be alert to the possibility of self-inflicted contact dermatitis induced by exposure to plants, especially to A. americana. Systemic signs may accompany the cutaneous lesions.

Penetrating injuries of the vertebral artery are not common. Although surgical control of this type of injury is well- documented, the combined approach (surgery and packing for temporary control of bleeding, followed by angiography and embolization for permanent control) is now recognized and practiced.

We describe a 40-year-old man who was stabbed in the neck. He was rushed to the operating theater in hemorrhagic shock. A vertebral artery injury was identified and packed. Angiography and embolization permanently controlled the bleeding.

The combined approach is safe and we recommend it in those in whom bleeding from the vertebral artery is initially well controlled with packing.

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.

Most cases of hyper-phenylalaninemia are due to deficiency of phenyl-alanine hydroxylase that converts phenyl-alanine to tyrosine. This enzymic reaction is facilitated by the co-factor tetrahydrobiopterin (BH₄). A defect in the latter substrate leads to increased phenyl-alanine in 1-2 cases per million live births. Such cases are characterized by a degenerative brain process, and pronounced neurologic symptoms that cannot be prevented by a low phenyl-alanine diet alone.

In 3 male newborns a deficiency of dihydropteridine reductase (DHPR) activity was diagnosed, the last in a sequence of 3 enzymes involved in the formation of BH₄. Successful outcome of treatment as well as the results of failure to diagnose and treat affected newborns are described, with emphasis on the logistic problems involved in mass screening.

Maintenance of bronchopulmonary hygiene is mandatory for preventing complications of respiratory therapy in the hospitalized patient. Removal of secretions from the tracheobronchial tree is crucial. Conventional therapy, designed to assist in dislodging airway secretions, includes chest physical therapy, incentive spirometry, transnasal endotracheal suctioning and bronchoscopy.

Minitracheostomy was first described by Matthews and Hopkinson for recurrent endotracheal suctioning in 1984. Since then there have been few papers about it, but they report good results with low morbidity. Despite this, its use is not popular in routine clinical work.

We report our experience with minitracheostomy in the prevention of sputum retention. We conclude that its use is easy, safe and very effective in preventing postoperative and post-traumatic respiratory complications.

The femoral artery remains the most used peripheral site for radiological catheter access. With a greater number of both diagnostic and therapeutic procedures being performed by interventional radiologists and cardiologists, and with larger catheters being used for stenting and endovascular grafting, the incidence of iatrogenic pseudo-aneurysms reported has reached as high as 0.5-2%. Ideally, they should thrombose spontaneously. However, when this does not occur, management options include: observation, ultrasound-guided obliterative compression, direct thrombin injection, embolization, stent graft insertion, and very rarely- surgery.

During a 7-year period (1992-1999) we treated 131 cases of femoral artery false aneurysms. Until 1998 ultrasound-guided compression-obliteration, with a 95% success rate, was our method of choice. Since 1998, direct thrombin injection, with 100% success in 24 cases, has become our preferred method. It is pain-free, fully successful even in anticoagulated patients, and is currently our treatment of choice.

Liver transplantation is the treatment of choice for end- stage liver disease. During the past 8 years we performed 102 liver transplants in 84 adults and 16 children. In the adults, 9 were combined transplants: 1 a liver-pancreas transplant for type I diabetes, and 8 liver-kidney transplants. In the children, transplants included 5 whole-livers, 5 left-lateral liver segments from living-related donors, 4 reduced-grafts of right or left lobes, and 2 split left-lateral segments.

At a mean follow-up of 31 months (range 1-96) 70 were alive, 3 had died during surgery and 15 during the first postoperative months. Mortality was due to primary graft non-function (7), sepsis (10), intracranial hemorrhage (1), tumors (4), recurrent hepatitis B (2), biliary strictures (2) and chronic rejection (1). The 1- and 4-year survival rates were 79.5% and 69.6%, respectively.

After transplantation, 10 developed biliary stricture (5 corrected by balloon dilatation) and 8 anastomotic stricture (7 corrected by surgery), and there were 2 multiple intra-hepatic strictures. There was hepatic artery thrombosis in 5, including 4 children. In 3, grafts were salvaged by thrombectomy and 2 others underwent re-transplantation. In those who survived transplantation by more than 1-month, recurrent hepatitis B was seen in 6 of 17 (35%) and recurrent hepatitis C in 12 of 19 (63%).

Thus, results of our first 100 liver transplants are similar to those reported by larger centers, showing that in an appropriate setting good results can be achieved by small transplant programs.

Nutritional status and vitamin B⁶ status were assessed in 18 men and 32 women, average age 84, living in a home for the aged. Average proportion of energy derived from protein was higher than the recommended; fiber intake was very low. Also low were intakes of calcium, magnesium, zinc, copper, vitamins D and E, thiamin, folic acid and vitamin B⁶.

Supplementation with vitamin B⁶ (10mg/d) for 28 days in those with the lowest B⁶ status assessed by B⁶ intake, activation coefficient of aspartate transaminase and plasma pyridoxamine concentrations led to improved B⁶ status (marked decrease in activation coefficient) and increased synthesis and decreased degradation of many short-lived neutrophil proteins. Though our elderly enjoy a variety of foods, some have marginal deficiencies that can be improved. Therefore, in the institutionalized elderly, micronutrient supplementation should be administered at a level low enough to be safe (below recommended upper level of intake) but high enough to be effective.

The medical records of all patients referred to the emergency department (ED) of Sheba Medical Center for renal colic during 1996 were analyzed. Patients discharged from the ED and those hospitalized were compared.

There was no significant difference between the 2 groups with regard to average age or sex distribution. Statistically significant differences were found with regard to frequency of chills and fever, history of renal colic, referral for renal colic during that year or hospitalization for renal colic or nephrolithiasis, previous positive imaging, stone removal by surgery or extracorporeal shock wave lithotripsy, fever exceeding 37.5^o and administration of fluids, pethidine or pramin in the ED, prolonged stay in the ED and previous appendectomy.

A conditional regression model tested the predictive value of each of those factors. Inclusion of independent variables into the model led to an overall correct classification rate of 84.43%, with 44.83% sensitivity and 93.16% specificity. There were correlations between referrals for renal colic, overall renal colic rate and average monthly temperature, so there was no pure correlation between average monthly temperature and referrals to the ED for renal colic.

The major indications for hospitalization were actually the clinical ones, indicating either an active metabolic disease or suspected obstruction of the urinary tract. Treatment in the ED and duration of the visit indicated disease severity.

We examined all ceftriaxone-resistant Escherichia coli isolates obtained from clinical samples during 16 months (1 Dec. '97 - 31 Mar. '99). A total of 97 resistant isolates from 36 patients were obtained, mostly from urine specimens. Of these patients, 35/36 were over 75 years old, most lived in nursing homes, were dependent on nursing in their daily lives, and were incontinent and/or had indwelling catheters.

All 97 isolates had similar susceptibility profiles: resistant to ciprofloxacin, gentamicin, ampicillin, amoxycillin/clavulanate, tricarcillin/clavulanate, aztreonam, and cefuroxime; decreased susceptibility to ceftazidime and cefepime; and susceptible to imipenem and meropenem. Double-disc tests indicated that all strains produced extended spectrum beta-lactamase(s). All the isolates belonged to 1 of 3 E. coli serotypes: 79 were 0153:H31, 13 were 0142:H10, and 5 were 0102:H6.

Acute flank pain is commonly encountered in the emergency department, and often requires imaging to establish its cause. For decades intravenous urography and sonography have been the primary media for evaluating flank pain.

Recently, noncontrast spiral CT (NCSCT) has been shown to be accurate and highly successful in diagnosing cause in such cases. We evaluated its use in the diagnosis of acute flank pain. During a 7-month period, 147 such cases had NCSCT imaging immediately after initial evaluation in the emergency department. Using a spiral CT scan without oral or IV contrast media, 109 of 147 cases were found to have ureteral stones, and 34 others to have other urological conditions unrelated to the cause of pain; 38 CT scans were negative for ureterolithiasis and in 14 non-urological disease was diagnosed.

NCSCT is a valuable diagnostic technique for patients in the emergency department with flank pain. It rapidly and accurately detects ureteral stones causing renal colic and also detects extra-urinary causes of acute flank pain.
