The effectiveness of sequential chemo-radiotherapy in preserving the larynx in advanced laryngeal carcinoma was assessed. 4 Unselected patients (19 men and 2 women, mean age 60 years) with advanced squamous cell carcinoma of the larynx (T3-4/N0-3) received induction chemotherapy consisting of 2-3 cycles of cisplatin (100 mg/m²) and 5-flourouracil (1000 mg/m²/day) as a continuous infusion on days 1-5 followed by definitive radiotherapy: 50 Gy to the whole neck, 70 Gy to the larynx and clinically involved nodes, using a combination of 6 MV photons and 9-12 MeV electrons.

19 of The 21 patients responded to combined therapy but there was no response to induction therapy in 2 (10%) and 2 did not complete therapy due to severe toxicity. At a mean follow-up of 40 months, 7 had undergone total laryngectomy (33%), for an overall 5-year laryngeal preservation rate of 66%. Reasons for total laryngectomy in 2 patients were no response and in 5 tumor recurrence.

Mean survival was 39 months (range 11-46 months); at last follow-up 17 of 21 were alive and disease-free, 11 of whom had a functional larynx (65% of survivors). 2 died due to disease progression and 1 due to a cardiovascular event. Sequential chemo-radiation allows laryngeal preservation in about 2/3 of surviving patients without compromising survival.

Palliative care of terminal cancer patients is one of the tasks of our Home Care Unit. Increasing hospitalization costs have brought forward the decision to treat them at home, assuming that they would prefer to return and die in their natural surroundings, among family.

Most of our patients are aged, recent immigrants from the Soviet Union, of low socioeconomic status; most live with their close families. Our care model combines social, cultural, economic, medical and nursing aspects. More patients choose to die at home, and that is where costs are minimal. Care management and characteristics of 44 terminal cancer patients, who died between January and October 1996, are described. Living with a family was not required for treatment at home. Length of care by the unit ranged from 1-48 weeks, with an average of 8.5 and a median of 6. 55% of patients were hospitalized, most (58%) for 5-9 days for noncancerous diseases, and then discharged home. 54% died at home, a third were hospitalized for 2-17 days before death. Compared to the average length of stay in palliative care oncology wards, 1044 days and more than NIS 500,000 were saved.

A telephone survey examined families' satisfaction with various components of care. 92% were satisfied with the home treatment. 79%-82% felt that the nurse and doctor of the team met their needs and expectations. Half the families were satisfied with the treatment of pain. Families in which treatment was 24 weeks or more were generally less satisfied than those with shorter treatment at home. We learned that an early entry into treatment is necessary; hospital referral criteria should consider to a greater extent the coping ability of families; nursing aid hours should be increased and professional emotional support added; additional pain control methods should be used. All these would strengthen families, improve quality of care, and contribute to additional savings by decreasing hospital stay.

This study was designed to assess possible diurnal fluctuations in the efficacy of thrombolysis with streptokinase. 156 consecutive patients treated with streptokinase during the period 1.1.95-1.7.96 were studied retrospectively. Success or failure of thrombolysis was determined according to the accepted clinical and angiographic criteria starting at midnight, 12 times at 2-hour intervals, then 8 times at 3-hour intervals, and then 6 times at 4-hour intervals. A definite peak for successful thrombolysis was found in the late afternoon and early evening hours. Between 16:00-20:00 PM, in 30.23% successful thrombolysis were observed, compared to 6.98% between 20:00-24:00 PM (p<0.05) and in 10.53% between 00.00-04:00 AM (p<0.05).

Multiple regression analysis showed that the independent factor with the greatest impact on successful reperfusion was the actual time until thrombolysis (p=0.037); then came the interval from pain onset to streptokinase administration (p=0.020), while age and gender had much lesser impacts (p=0.328 and 0.215, respectively), and individual risk factors even less.

These findings may have several clinical implications: dose adjustment for the time of day may be required, with larger doses needed during morning hours, or preference for primary coronary angioplasty to avoid increase in bleeding complications due to higher doses of thrombolytic agents.

Discontinuation of long-term, low-dose aspirin prior to ambulatory oral surgical procedures was assessed in a blind, controlled prospective study. 50 patients on low-dose aspirin who needed dental extractions, periodontal surgery, or other ambulatory oral surgery were randomly divided into test and control groups. The control patients stopped taking aspirin a week before operation, but in the test group aspirin was continued. Before, during and after surgery bleeding time was tested. Although bleeding time was significantly longer when aspirin was continued, in both groups it was within normal limits. Intraoperative hemorrhage was more frequent in those taking aspirin. Hemostasis control posed no problem and there were no postoperative complications in either group. It is concluded that discontinuing low-dose aspirin prior to elective oral surgery is not justified.

The results of properitoneal mesh repair of inguinal hernia were evaluated in 38 of 43 consecutive patients operated by Stoppa's technique. In 33 patients the hernia was bilateral and in 10 unilateral; in 20 it was recurrent. In 33/43 patients the mesh was fixed either by sutures or metal clips. The overall recurrence rate after 22 (14-36) months of follow-up, was 10.5%. This result was composed of a 3.0% recurrence rate in the fixated-mesh group, and 30.0% among those with non-fixated mesh.

The outcome following the Stoppa method for tension-free properitoneal mesh repair of inguinal hernia, compares favorably with those of other methods, provided proper attention is paid to adequate mesh placement and fixation. Further prospective studies are needed to define the role and indications for this technique in the laparoscopic era.

Cerebrovascular events have high mortality and morbidity, especially in the elderly. Ischemia is the main cause and 30% of the ischemic events are embolic and of cardiac origin. The clinical picture is not always typical of the type of stroke, but diagnosis of the mechanism of the event determines treatment. Transesophageal echocardiography (TEE) is a sensitive procedure more appropriate for diagnosing emboli of cardiac origin than transthoracic echocardiography (TTE). We therefor compared TEE and TTE in the determination of the source of emboli in 65 patients with ischemic stroke but without significant atherosclerotic changes in their carotid arteries, and compared these findings with those in 50 patients without stroke. 68% of the patients had potential sources of emboli according to TEE, compared to only 15% according to TTE. In the control group only 24% had potential sources of emboli by TEE. The findings were: clots in the left atrium, severe aortic atheroma, patent foramen ovale with paradoxical shunt, spontaneous echocardiography contrast, vegetations and mitral valve prolapse. The study showed that TEE is better than TTE in detecting the etiology of embolic stroke in those with normal carotid arteries, thus determining appropriate management.

Circadian Fluctuations of the Signal-Averaged ECG

Circadian periodicity for the time of onset of acute myocardial infarction has been shown; the early morning peak of infarction coincides with the onset of other related phenomena, including sudden cardiac death, ventricular arrhythmias, thrombotic stroke, etc. Late potentials detected by the signal-averaged ECG are considered to be independent markers of vulnerability to ventricular arrhythmias. The signal-averaged ECG enables the amplifying and recording of small bioelectric signals of cardiac origin, while eliminating extraneous electrical "noise." To determine whether late potentials are themselves subject to circadian influence, 31 patients (age range 41-79) who had had an old or recent myocardial infarction underwent late potential assessment by the signal-averaged ECG. 4 indices were studied: duration of late LPD potentials (LPD), total QRS duration (TQRS), and root mean square voltage of the last 40 msec, and of the last 50 msec (RMS 40 and RMS 50). These indices were assessed 3 times, during the early morning hours, at noon and during the evening. Morning LPD differed significantly from noon and evening LPD and the morning RMS 40 similarly differed from noon and evening values. TQRS and RMS 50, even though remaining in the normal range, also showed a tendency to abnormal values during morning hours. These findings could possibly be related to the early morning incidence peaks of severe ventricular arrhythmia and sudden cardiac death, since abnormal late potentials constitute the physiopathological basis for certain ventricular arrhythmias.
