The National Institutes of Health (NIH) held a consensus conference which recommended 5-FU and levamisole as adjuvant chemotherapy for colon cancer MAC (Modified Astler Coller) stage C.

From 1991-1994, 37 such patients diagnosed here were treated with 5-FU (intravenous dose of 450/mg/m²/d for 5 days and from day 29, once a week for 48 weeks) and oral levamisole (50 mg 3 times/d. for 3 days, every 2 weeks for a year), as suggested by NIH guidelines.

16 patients were males and 21 were females, mean age was 62 years and median 64. Cancer locations were: right colon (in 16, 43%), left colon (19, 51%), multiple colon primaries (2, 1%). 25 (68%) had 1-3 positive lymph nodes and 12 (32%) had 4 or more positive lymph nodes.

Only 20 (54%) finished treatment as prescribed. In the others, 1 or both drugs caused side-effects for which the drugs had to be stopped. 6 patients relapsed while on treatment.

The most common side-effects were diarrhea, stomatitis and bone marrow suppression. 3 were hospitalized due to neutropenic fever. 5-year actuarial survival of all patients was 61%; 5-year relapse-free survival was 61%; 5-year relapse-free survival of right versus left colon was 41% and 82%, respectively (p<0.01). There was no significant difference in 5-year survival of those with 1-3 positive lymph nodes as compared to those with 4 or more (62% and 56%, respectively). 5-year survival in those who finished or did not finish treatment (excluding those who stopped treatment because of progressive disease) was 83% and 70%, respectively (NS).

The 5-year survival of our series was similar to that of patients treated similarly elsewhere. The 5-FU and levamisole treatment was not tolerated well by our study population. It has recently been replaced in our service by a 5-FU and leucovorin regimen given for 6 months.

Many Faces of Parvovirus

George Habib, Leon Cohen

Carmel Medical Center, Haifa

2 women, aged 31 and 37 years, respectively, suffered from acute febrile illness due to acute infection with human parvovirus B19. 1 also had a maculopapular rash and articular symptoms after her fever stopped, a clinical picture typical of erythema infections. The other had leukopenia and thrombocytopenia and had received dipyrone. Although acute infection with human parvovirus usually occurs in childhood, it may also occur in adults, with protean manifestations.

We report our initial experience with laparoscopic ligation of spermatic veins in the treatment of varicocele in adolescence. 19 boys, 13 to 18 years old, underwent this treatment between I 1997 and III 98. The varicocele was always on the left side. 12 complained of scrotal discomfort and pain, but in 7 it was found incidentally during routine medical examination by the family or school physician. The diagnosis was based only on physical examination.

There has been no morbidity related to the laparoscopic procedure and all returned to normal activity within a few days. Follow-up 2-12 months after surgery showed no varicocele in any. We conclude that laparoscopy is useful in the treatment of varicocele in adolescents.

Kikuchi-Fujimoto disease in a self-limited lymphadenopathy that can be confused histologically and clinically with lymphoma or systemic lupus erythematosus. It was diagnosed in a 37-year-old woman presenting with fever, cervical, submandibular and axillary lymphadenopathy, weight loss and recurrent urinary tract infections. Lymph node biopsy was consistent with the diagnosis of a histiocytic necrotizing lymphadenitis. Early diagnosis of Kikuchi-Fujimoto disease can prevent harmful treatment.

Diarrheal disease tends to spread from infected children to their families. Due to the increased risk of exposure, children's caregivers in day-care centers may have a higher incidence of diarrhea, particularly when caring for very young children. We therefore examined the incidence of diarrhea and antibodies to Shigella among caregivers in day-care centers, according to age groups of children in their care (<18, 18-34, and >35 months) and in comparison with the general population. 2 studies with a retrospective cohort and seroepidemiological cross-sectional design were carried out. Questionnaires were completed by 401 caregivers in 36% of all WIZO day-care centers. As a measure of past exposure to Shigella, levels of S. sonnei and S. flexneri antibodies were examined in the blood of 110 caregivers (ELISA method).

There was a higher incidence of diarrhea among young children, increasing the potential exposure to diarrheal agents among their caregivers. Nevertheless, no statistically significant differences in diarrhea incidence were found among caregivers of the various age groups during the previous year (p=0.768) and during the previous month (p=0.319), nor in absenteeism due to diarrhea during the last month (p=0.761). Levels of Shigella antibodies were similar among caregivers in all 3 groups. Diarrheal incidence was higher among women in the population control group than among caregivers during the previous year (p=0.005) and month (p=0.067). No statistically significant differences in levels of S. sonnei and S. flexneri antibodies were found between caregivers and women in the control group.

There was no evidence that diarrhea is an occupational hazard for caregivers of young children. An explanation may be the development of protective immunity against common diarrheal agents due to recurrent exposure.

From January 1994 to July 1997, 20 boys 1.5-13 years of age underwent laparoscopic examination and treatment for non-palpable testis. In 1 there was bilateral nonpalpable testis. Only 3 had intra-abdominal testes viable for orchiopexy. In 8 atrophic testicles were removed and in 9 laparoscopic examination revealed intra-abdominal blind ending of the spermatic cord and no testicular tissue.

We conclude that laparoscopy is a useful and safe technique for accurate diagnosis and may avoid additional intervention in treating non-palpable testes. Furthermore, intra-abdominal testes may be managed laparoscopically under the same anesthetic.

28 in-patient units were surveyed during a 5-day period to determine the extent of the use of physical restraints in hospitalized patients. Information was gathered on the characteristics of restrained patients and indications for use and removal of restraints, patterns and means of restraints, monitoring, and written notations. 31 different patients (6% of those surveyed) were restrained in 13 units during the 5 days of the survey, an average of 15 (3%) daily.

Characteristics of restrained patients were: age 70 and over requiring emergency hospitalization, reduced level of consciousness, limitation of mobility, incontinence, history of 2 or more chronic diseases, requiring multiple drugs, and use of multiple medical devices. Bilateral, soft hand restraints were most often used to prevent patients from removing tubes. Nurses initiated the decision to apply or remove restraints, which were usually removed as the patients' condition improved. Written policies were lacking regarding monitoring and follow-up of restrained patients. Clearly written policies and increased staff awareness of potential hazards may reduce the use of restraints and the length of time they are employed.

Ultrasonographic findings of superior sagittal sinus thrombosis include dilated and hyperechoic sinus (direct imaging of the thrombus). No flow should be demonstrated by the various Doppler techniques. In the deeper sinuses, if the thrombus can not be visualized after a negative Doppler study, MR imaging is recommended. Recanalization and reflow can be demonstrated on follow-up study.

During the winter of 1995, nasopharyngeal colonization of Streptococcus pneumoniae was evaluated in 204 children with respiratory infection and 107 normal control children. There was no difference in gender or mean age between the groups, and no difference in carrier rate between sick (24.5%) and normal (22%) children (p=0.6). Carrier rates were 19%, 32%, 31% and 17% at 6, 12, 24 and 48 months, respectively. Penicillin-resistant pneumococci (PRP) were found in 42% of sick and 16.6% of normal children, (p<0.05). Resistance to more than 2 antibiotics was found in 28% of sick and in 12.5% of normal children. PRP were found in 67% and 34% of sick children with and without prior antibiotic treatment (p<0.05). We conclude that there is no difference in the carrier rate of Streptococcus pneumoniae between sick and normal children. However, the high prevalence of PRP in children with respiratory infections is probably due to prior antibiotic treatment.

We treated 2 women and 8 men suffering from Fournier's gangrene during 1990-96. 2 had diabetes, 1 suffered from ulcerative colitis and 1 was an alcoholic. In 8 of them the infection was triggered by a mixture of aerobic and anaerobic bacteria. Treatment consisted of repeated wide debridement and early colostomy. This aggressive approach resulted in relief of the septic signs within 24 hours and permitted early skin grafting of the wounds. 2 patients died due to sepsis that caused multiple organ failure. The 8 who survived were hospitalized for an average of 35 days. On follow-up examination 1-5 years later all patients had undergone closure of the colostomy and were completely rehabilitated.

Fournier's gangrene is not rare in the geriatric population. We believe that early diagnosis and aggressive wide debridement, combined with early colostomy, are the keys to successful treatment.

Spectral analysis of heart rate variability (HRV) has been shown to be a reliable noninvasive test for quantitative assessment of cardiovascular autonomic regulatory response, providing a dynamic map of sympathetic and parasympathetic interaction. In a prior study exploring the state of hyperarousal that characterizes the post traumatic stress disorder (PTSD) syndrome, we presented standardized heart rate analyses in 9 patients at rest, which demonstrated clear-cut evidence of a baseline autonomic hyperarousal state.

To examine the dynamics of this hyperarousal state, standardized heart rate analysis was carried out in 9 PTSD patients, compared to a matched control group of 9 normal volunteers. 20-minute ECG recordings in response to a trauma-related cue, as opposed to the resting state, were analyzed. The patients were asked to recount the presumed triggering traumatic event, and the control subjects recounted a significant stressful negative life event.

Whereas the control subjects demonstrated significant autonomic responses to the stressogenic stimulus of recounting major stressful experiences, the patients demonstrated almost no autonomic response to the recounting of the triggering stressful event. The patients demonstrated a degree of autonomic dysregulation at rest comparable to that seen in the control subjects' reaction to the stress model.

The lack of response to the stress model applied in the study appears to imply that PTSD patients experience so great a degree of autonomic hyperactivation at rest, that they are unable to marshal a further stress response to the recounting of the triggering trauma, as compared to control subjects. A subsequent study of the effect of medication on these parameters showed that they are normalized by use of selective serotonin re-uptake inhibitors (SSRI's).

Neither the clinical implications of these findings, nor their physiological mechanisms are clear at present. We presume that they reflect a central effect, as the peripheral automatic effects of SSRI's are relatively negligible.

112 patients with localized prostate cancer, clinical stage A2-C, were treated by definitive radiotherapy between 1982-1988. Radiation volume encompassed the prostate, seminal vesicles and pelvic lymph nodes. The 10-year actuarial survival figures were: overall 51%; stage A2 87%; stage B 50%; stage C 36%; well differential tumors 67%; moderately differentiated 50%; poorly differentiated 32%; patients with local tumor control 55%; and patients with minimal local control 36%. It is concluded that external beam irradiation is effective in localized prostatic cancer. Stage and grade are prognosticators of survival.

Osteoid Osteoma of the Patella

Osteoid osteoma is a primary, benign, bone tumor with a typical X- ray appearance. The diagnosis is usually straightforward when it involves the long bones of the leg. However it may occur in unusual locations, such as in flat and cancellous bones. The following case demonstrates the difficulty in diagnosing it in an extremely rare site. A 25-year-old woman with long-standing anterior, right knee pain had had 3 interventions: 2 diagnostic arthroscopies and a distal, femoral biopsy. Since there had been no improvement in her condition, the diagnosis of osteoid osteoma of the patella was suggested, supported by recent X-ray and scintigraphicfindings. This rare condition was confirmed by biopsy of the upper pole of the patella, a procedure that was followed by complete recovery. 6 years later, she is now completely free of pain and has no clinical or X-ray evidence of recurrence.Review of the literature revealed only 5 previously reported cases of osteoid osteoma of the patella. All were diagnosed relatively late and in 1 the tumor was diagnosed only after total patellectomy. Diagnosis of these rare cases that mimic much more common causes of patello-femoral pain demands a high index of suspicion.

2 women with quinidine-induced lupus are presented. This condition is rare; only about 30 cases have been reported in the English literature. Both our patients had arthritis of the wrist, antinuclear antibodies with homogenous pattern and elevated ESR. Anti-double stranded DNA antibodies were present in 1 patient, and a petechial rash in the other. Complete resolution of arthritis occurred within a few days after quinidine withdrawal, but antinuclear antibodies persisted for several months.
