The antiphospholipid syndrome (APS) is defined by the presence of antiphospholipid antibodies (aPLs) with venous or arterial thrombosis, recurrent pregnancy loss or thrombocytopenia. The syndrome can be either primary or secondary to an underlying condition, most commonly systemic lupus erythematosus (SLE).

The purpose of the study was to review the manifestations of the APS in Israeli patients and to investigate the difference between patients with primary or secondary syndrome. Analysis of the correlation between the manifestations of the disease and the antibody titers [LA (lupus anticoagulant), IgG aCL (anticardiolipin), IgM aCL] was also performed.

In the study there were 90 patients with APS in the Sheba Medical Center. The clinical findings for all patients were recorded according to established protocol.

Results: Arterial thrombotic events were present in 51.1% of the patients; cereberal ischemic attacks were the most frequent arterial events. Venous thrombotic events were present in 45.6% patients; deep venous thrombosis was the most frequent venous event. Obstetric complications were found in 37.3% of patients; the most frequent complication was abortions. The clinical findings of patients with primary or secondary syndrome were similar. Patients with APS associated with lupus had a high prevalence of hemolytic anemia (28.6% v 3.3%; P=0.001), and ANA (antinuclear antibody) (75% v 12.9%; P=0.0001). There was no correlation between the antibody titers (LA, IgG aCL, IgM aCL) and clinical manifestations. The patients received anticoagulant treatment and antiaggregant drugs to prevent recurrence of symptoms. Clinical manifestations in Israeli patients did not differ from those in non-Israeli patients.

Conclusions: Venous or arterial thrombosis and obstetric complications are the most frequent clinical findings in APS. There was no different in clinical manifestations between primary and secondary syndrome. The findings of autoimmune hemolytic anemia and ANA were more frequent in patients with secondary APS. There was no correlation between antiphospholipid antibody titers and manifestations of disease. Overall, the patients require therapy with anticoagulant treatment and antiaggregant drugs. The clinical manifestations were similar in Israeli and non-Israeli patients.

The treatment of traumatic false aneurysm of the thoracic aorta by endovascular stent graft may have advantages over conventional surgery. This is a case study of two women suffering from false aneurysm of the thoracic aorta caused in one by a knife injury and in the other by a car accident. After the patients became hemodynamically stable, a commercially available endothelial stent graft (Talent, Gor) was deployed. Recovery was rapid in the first patient. The second patient required emergency laparotomy for venous bleeding one day after stent placement; she died two weeks later, mainly from organ failure.

Conclusions: Endovascular techniques can be used in selected cases to treat thoracic false aneurysms thereby avoiding the complexity and morbidity of conventional surgery.

The first 1,000 laparoscopic cholecystectomies performed in our department were reviewed. There was no operative mortality; conversion to open cholecystectomy was necessary in 2%. In the last 600 cases the rate of conversion had decreased to 0.5%. There was common bile duct injury in 0.3%, with the injuries identified during primary surgery. This clinical experience is consistent with previous studies, which proved that laparoscopic cholecystectomy is safe and should replace open operation as the procedure of choice. 

Current Trends in Surgery for Female Urinary Stress Incontinence

Dept. of Obstetrics and Gynecology, Shaare Zedek Medical Center, Jerusalem

Quality of life of 5% of the female population is impaired by urinary stress incontinence. Its cause is pelvic floor relaxation and the cure is surgical. The most widely performed operations are retropubic colposuspensions and sling operations, which have relatively high, well-proven cure rates. Yet because of the long rehabilitation required, gyneco-urologists seek minimally invasive ways to solve the problem.

Vaginal colporrhaphy and laparoscopic operations are not common, but the recently reported TVT might become popular if proven effective.

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

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.

37 candidates for epilepsy surgery underwent the intra-carotid amytal procedure (IAP; also known as the Wada test) to determine hemispheric speech dominance and memory capacity. 31 demonstrated left hemisphere speech dominance, 2 showed evidence for bilateral language and 4 demonstrated right hemispheric language dominance.

Our study supports a correlational relationship between handedness, lesion laterality and age of onset of seizures, as reported in earlier studies. Left-handed patients with a left hemisphere lesion whose seizures began to an early age had a strong tendency for reversed language dominance.

Asymmetry of at least 20% in performing the memory test was taken as the cutoff score for demonstrating laterality of lesions. The asymmetry score correctly predicted laterality of lesions in all 28 patients; 6 did not have asymmetry scores and 3 were examined for language only. None of the patients who successfully passed the Wada memory test had any significant postsurgical memory deficits; 1 had transient reduction in verbal memory and 4 who did not pass the test were not operated on for this reason.

Our results demonstrate the importance of the Wada test in determining cerebral speech dominance, in predicting post-surgical amnesia, and support its usefulness in predicting laterality of seizure focus in candidates for temporal lobectomy.

Among patients seen for epileptic seizures, there is a subgroup of those who do not have epilepsy but suffer from psychogenic paroxysmal events which mimic epileptic seizures. The differential diagnosis between them is of the utmost importance, as incorrect diagnosis of seizures subjects the patient to incorrect management. In the case psychogenic status epilepticus, the treatment may endanger the patient.

We report 3 women, aged 20, 20 and 28 and a man aged 24 with psychogenic status epilepticus admitted to an intensive care unit and treated by induction of phenobarbital coma when other antiepileptic medication failed.

Sacrospinous ligament fixation is a well-known method for correction of vaginal vault prolapse. The procedure is primarily indicated after hysterectomy and as a prophylactic measure for total uterine prolapse.

8 women with post-hysterectomy vaginal vault prolapse aged 48-72 years, were referred 1-25 years following primary surgery. Sacrospinous ligament fixation was elected to enable simultaneous correction of cystocele and rectocele, and to preserve sexual function. All operations were completed without significant complications.

In 6 of the 8 patients located for long-term interview, 1 reported mild bulging of the introitus, another mild urinary stress incontinence, urgency and frequency and 1 reported frequency only. Sexual function in 4 was without complaints. Defecation in all patients was normal.
We conclude that this operation is safe and effective. We encourage gynecologic surgeons to consult an experienced tutor prior to performing this procedure, as this type of surgery is quite dangerous and many gynecologists are not familiar enough with it.

A 3.5-year-old boy with developmental motor retardation, hypotonicity, and severe speech disturbance had alpha-amino adipic acid in his blood and very high levels in his urine. In only 20 cases has this catabolite of lysine and hydroxylysine been found in high concentrations in urine, due to enzymatic block.

The clinical features associated with alpha-amino adipic aciduria may include mental retardation, developmental and motor delay, learning difficulties, convulsions, speech problems and ataxia. 3 siblings had milder symptoms of psychomotor delay and intermediate degrees of alpha amino-adipic aciduria, suggesting that the described developmental deficits could be related to this metabolite or its derivatives.

Can Police Car Flashing-Light Induce Encephalographic Discharges and Seizures?

The new police car flashing-light device (930 Heliobe Lightbar) has recently been implicated as potentially epileptogenic. We exposed 30 epileptic patients, 30 nonepileptic patients who suffered from headache and 15 normal volunteers to this light source. All had routine EEGs with standard intermittent photic stimulation, followed by 3-minute stimulation with the Lightbar. In none were either seizures or EEG changes induced. In 1 epileptic spike-and-wave activity induced by standard photic stimulation was enhanced with the Lightbar.

We could not confirm that the Lightbar is epileptogenic.

After 3-5 years of continuous use of 1-dopa preparations for Parkinson's disease, 25%-50% of patients develop side-effects such as the "on-off" phenomenon and involuntary movements that markedly impair function. One cause of these manifestations is evidently a disturbance in the absorption of 1-dopa.

We attempted to avoid this problem by using subcutaneous injections. Apomorphine is a rapid-acting dopamine agonist which causes a return from "off" to "on" within minutes.

We present the results of a trial of subcutaneous injections of apomorphine in 22 Parkinsonian patients (12 males, 10 females) with severe motor fluctuations. During 5 days prior to the apomorphine all received Motilium (domperidone, 60 mg/d) to prevent nausea and vomiting. All were hospitalized initially to determine optimal dosage and to teach them the technique of self-injection.

2 to 4 mg of apomorphine were injected 1 to 3 times daily for 2 to 12 months. In 17 patients (80%) "off" periods were reduced without significant side-effects. Apomorphine seems to be effective, tolerable treatment for shortening 1-dopa induced "off" periods.

Female urinary stress incontinence diminishes the quality of life of about 5% of women. It is usually dealt with by surgery to correct the relaxed pelvic floor, the cause of the incontinence.

Tension-free vaginal tape is used in a newly described procedure. It consists of the vaginal introduction of a prolene needle-guided mid-urethral sling. The procedure is easy to perform under local anesthesia, recovery is rapid, and results are similar to those of other effective operations.

We report 44 patients who underwent this type of surgery. There were no significant complications. The early results were good and although the follow-up has been short, we believe that experience with this operation will play an important role in the treatment of urinary stress incontinence.

Familial hemiplegic migraine is a rare autosomal, dominant, migraine subtype. It is characterized by acute episodes of hemiplegia and hemisensory deficits, and other neurological abnormalities occurring either before or together with severe headache, nausea and vomiting; episodes last several hours and then spontaneously subside. Intervals between episodes are relatively prolonged. Unless there is a relevant family history suggesting this syndrome, the diagnosis is usually delayed. Recently the gene for the syndrome was identified on chromosome 19. We report 3 boys and 1 girl, 11-15 years old with hemiplegic migraine.
