Abstract
BACKGROUND Secular trends in old-age mortality are of crucial importance to population ageing. For the understanding and prediction of these trends, it is important to determine whether birth cohort effects, i.e. long-lasting effects of exposures earlier in life, are important in determining mortality trends up to old age. This study aimed to identify and describe cohort patterns in trends in mortality among the elderly (>60 years of age) in seven European countries. METHODS A standard age-period-cohort analysis was applied to all-cause and cause-specific mortality data by 5-year age groups and sex, for Denmark, England and Wales, Finland, France, The Netherlands, Norway, and Sweden, in the period 1950-99. RESULTS Cohort patterns were identified in all countries, for both the sexes and virtually all causes of death. They strongly influenced the trends in all-cause mortality among Danish, Dutch, and Norwegian men, and the trends in mortality from infectious diseases, lung cancer (men only), prostate cancer, breast cancer, and chronic obstructive pulmonary disease (COPD). All-cause mortality decline stagnated among Danish, Dutch, and Norwegian male birth cohorts born between 1890 and 1915, among French men born after 1920, and among women from all countries born after 1920. Where all-cause mortality decline stagnated, cohort patterns in mortality from lung cancer, COPD, and to a lesser extent ischaemic heart diseases, were unfavourable as well. For infectious diseases, stomach cancer, and cerebrovascular diseases, mortality increased among cohorts born before 1890, and decreased strongly thereafter. CONCLUSIONS Cohort effects related to factors such as living conditions in childhood and smoking in adulthood were important in determining the recent trends in mortality among the elderly in seven European countries.

Abstract
OBJECTIVE To evaluate how often coding changes between and within revisions of the International Classification of Diseases (ICD) complicate the description of long-term trends in cause-specific mortality. METHODS Data on cause-specific mortality between 1950 and 1999 for men and women aged 60 and older were obtained from Denmark, England and Wales, Finland, the Netherlands, Norway and Sweden. Data were obtained by five-year age groups. We constructed a concordance table using three-digit ICD codes. In addition we evaluated the occurrence of mortality discontinuities by visually inspecting cause-specific trends and country-specific background information. Evaluation was also based on quantification of the discontinuities using a Poisson regression model (including period splines). We compared the observed trends in cause-specific mortality with the trends after adjustment for the discontinuities caused by changes to coding. FINDINGS In 45 out of 416 (10.8 %) instances of ICD revisions to cause-specific mortality codes, significant discontinuities that were regarded as being due to ICD revisions remained. The revisions from ICD-6 and ICD-7 to ICD-8 and a wide range of causes of death, with the exception of the specific cancers, were especially affected. Incidental changes in coding rules were also important causes of discontinuities in trends in cause-specific mortality, especially in England and Wales, Finland and Sweden. Adjusting for these discontinuities can lead to significant changes in trends, although these primarily affect only limited periods of time. CONCLUSION Despite using a carefully constructed concordance table based on three-digit ICD codes, mortality discontinuities arising as a result of coding changes (both between and within revisions) can lead to substantial changes in long-term trends in cause-specific mortality. Coding changes should therefore be evaluated by researchers and, where necessary, controlled for.

Abstract
PURPOSE To assess whether the stagnation in old age (80+) mortality decline observed in the Netherlands in the 1980s, continued in the 1990s and which factors contributed to this stagnation. Emphasis is on the role of smoking. METHODS Poisson regression with linear splines was applied to total and cause-specific (3-digit) mortality data by age, year of death (1950-1999) and sex. Age-period-cohort analysis was conducted to determine whether the trends followed period and/or cohort patterns. ICD Revisions were bridged using a concordance table. RESULTS A sudden reversal in old age mortality occurred around 1980, leading to a stagnation in the decline and even an increase during the 1980s and 1990s. Smoking related cancers, COPD and diseases specifically related to old age contributed to this stagnation. Trends in smoking-related cancers and COPD showed a cohort pattern--especially for males. When excluding these smoking related diseases, the trends in old-age mortality in the Netherlands showed an increasing stagnation for both sexes. IMPLICATIONS Generation-wise changes in smoking can only partly explain the stagnation in mortality. Other factors like increased frailty and changes in medical and social services for the elderly probably have played a more decisive role in explaining the recent stagnation.

Abstract
OBJECTIVE Different from the general observed decline in old-age mortality, for The Netherlands and Norway there have been reports of stagnation in the decline since the 1980s. We detect periods of stagnation in recent old-age mortality trends, and explore for which causes of death the recent stagnation is most apparent. STUDY DESIGN AND SETTING We applied Poisson regression analysis to total and cause-specific mortality data by age (80+), period (1950-1999), and sex for seven European low-mortality countries. RESULTS We found large heterogeneity in the pace of decline in the countries under investigation, with periods of stagnation being widespread. In the 1980s and 1990s, stagnation was observed in Denmark, The Netherlands, and Norway (males). Continued mortality decline was observed especially in France. Although smoking has had a marked influence on the trends in old-age mortality, the role of smoking in the recent stagnation seems only modest and restricted to Norway. Mortality from cardiovascular diseases showed important crossnational variations in the pace of decline. Mortality from diseases specifically related to old age increased recently in all countries, except France. CONCLUSION Old-age mortality seems highly plastic and susceptible to many factors, with both favorable and unfavorable effects on trends over time.

Abstract
BACKGROUND Complex regional pain syndrome type I (CRPS I) develops as a consequence of trauma affecting the limbs, without obvious nerve lesion. Its features include pain, edema, autonomic dysfunction, movement disorder, and trophic changes. CNS involvement is suggested by the symptoms, but the pathophysiology of CRPS I is unknown. OBJECTIVE To assess excitability changes in the motor cortex in patients with CRPS I. METHODS The authors studied 25 patients with unilateral CRPS I involving the hand by means of transcranial magnetic stimulation using a paired-pulse paradigm. Motor threshold (MT) and intracortical inhibition and facilitation were determined on the affected and the clinically unaffected side. A control group of 20 healthy subjects was studied. RESULTS The authors found a significant reduction of intracortical inhibition on both sides of patients with CRPS compared with control subjects, whereas intracortical facilitation and MT did not differ significantly. However, in the patients' group, the presence of allodynia significantly decreased MT. CONCLUSIONS The authors showed a bilateral disinhibition of the motor cortex in patients with complex regional pain syndrome.

Abstract
We aimed to assess the relationship of the angiogenic cytokines VEGF-A, VEGF-C, and VEGF-D and their receptors VEGFR-2 and VEGFR-3 in the adenoma-carcinoma sequence and in metastatic spread of colorectal cancer (CRC). mRNA expression levels were measured using semi-quantitative reverse transcription polymerase chain reaction in 70 CRC (35 with paired mucosae) and 20 adenomatous polyps. Immunohistochemistry and ELISA assessed protein expression. VEGF-D mRNA expression was significantly lower in both polyps and CRCs compared with normal mucosa (P=.0002 and.002, respectively), whereas VEGF-A and VEGF-C were significantly raised in CRCs (P=.006 and.004, respectively), but not polyps (P=.22 and P=.5, respectively). Receptor expression was similar in tumor tissue and normal mucosae. Tumors with lymph node metastases had significantly higher levels of VEGF-A compared with non-metastatic tumors (P=.043). There was no association between VEGF-C or VEGF-D and lymphatic spread. The decrease in VEGF-D occurring in polyps and carcinomas may allow the higher levels of VEGF-A and VEGF-C to bind more readily to the VEGF receptors, and produce the angiogenic switch required for tumor growth. Increased expression of VEGF-A within CRCs was associated with lymphatic metastases, and therefore, this member of the VEGF family may be the most important in determining metastatic spread.

Abstract
OBJECTIVE We wanted to investigate plastic changes occurring in the motor and somatosensory cortex after upper limb amputation, and their possible relationship to phantom pain. METHOD To assess these plastic changes, we used transcranial magnetic stimulation (TMS) and source localization of somatosensory evoked potentials (SEP). Eleven patients with upper limb amputation were investigated. The phantom pain intensity was assessed by visual analogue scaling (VAS). RESULTS Using TMS mapping, we found a significant lateralization of the amplitude-weighted centre of gravity (P<0.01) and an enlargement of the excitable area (P<0.05) on the hemisphere contralateral to the amputation. SEP mapping showed a significant medialization of the N20 dipole (P<0.05) on this side. None of these changes correlated with the phantom pain intensity. CONCLUSIONS We conclude that after limb amputation, the relationship between plastic changes occurring in the sensorimotor cortex and phantom pain seems to be more complex than previously believed.

Abstract
Renal dysplasia (RD) is a common cause of chronic renal failure (CRF) in children. The evolution towards end-stage renal failure is unpredictable due to the paucity of early prognostic factors. In order to identify early prognostic clinical criteria, we have retrospectively analyzed renal function and growth in 11 infants with RD and CRF from birth up to 4 years of age. Children with obstructive RD were not included. Glomerular filtration rate (GFR) was estimated from Schwartz formula. In infants with a GFR below 15 ml/min per 1.73 m2 at 6 months of age (group A, n=5), kidney function did not further improve; 4 reached end-stage renal failure between 8 months and 6 years of age. In contrast, infants with a GFR above 15 ml/min per 1.73 m2 at 6 months of age (group B, n=6) experienced a significant improvement in renal function during follow-up, and none required renal replacement therapy. During the first 3 months of life all infants with RD and CRF developed severe growth retardation. Between 6 months and 4 years of age, children from group B grew significantly better than those from group A. In conclusion, our experience suggests that GFR, estimated from Schwartz formula at 6 months of age, is a useful prognostic factor in infants with RD and CRF. Infants with a GFR below 15 ml/min per 1.73 m2 are at risk of severe growth delay and the need for early renal replacement therapy, whereas those with a GFR above 15 ml/min per 1.73 m2 have a relatively favorable long-term prognosis.

Abstract
In our study we wanted to assess motor excitability in patients with upper limb amputation by means of transcranial magnetic stimulation (TMS). In 12 patients, TMS was applied using a paired pulse paradigm in order to test cortico-cortical excitability. Additional parameters of motor excitability like motor threshold and cortical silent period were also measured. Recordings from the amputated side were compared to the contralateral side and to healthy controls. We found a significant reduction of intracortical inhibition in forearm amputees and an enhancement of intracortical facilitation in upper arm amputees on the affected side. We conclude that after upper limb amputation, changes in the activity of intracortical interneuronal circuits appear in the affected hemisphere. These changes may depend on the level of amputation, and be the base of cortical reorganization.

Abstract
The aim of our study was to investigate the effect of the N-methyl-D-aspartate (NMDA) antagonist memantine on motor excitability in humans. Seven healthy volunteers received memantine or placebo, respectively, over a period of 8 days. At day 8, transcranial magnetic stimulation (TMS) was performed using a paired pulses paradigm in order to assess intracortical inhibition and facilitation. Additionally, motor threshold and silent period duration after TMS were measured as well as M waves, F waves and peripheral silent period after electrical peripheral nerve stimulation. Intracortical inhibition was enhanced, and intracortical facilitation reduced after memantine ingestion in comparison to placebo, whereas no significant difference could be observed regarding the other neurophysiological parameters. We conclude that the NMDA receptor is involved in the regulation of excitability of intracortical interneuronal circuits.

Abstract
The efficacy and tolerability of sertraline in 422 out-patients with major depression (DSM-III-R) was evaluated in an open multicentre 8-month study. Patients received sertraline 50 mg/day; if there was insufficient response at week 4, the dose was increased to 100 mg/day. After 8 weeks, 68.6% of patients had responded (> or = 50% reduction in Montgomery Asberg depression rating scale and clinical global impression scale scores of two or less (improvement of illness) and three or less (severity of illness); of patients receiving continuation treatment, 87.9% maintained at least a partial response at the final visit. The clinical response to the 50 mg/day dose was maintained throughout the acute treatment in 64% of patients. In all, 23% of the patients had mild or moderate drug-related gastrointestinal disturbances, which generally disappeared after 2 weeks. Only 8% of the patients withdrew because of side-effects. Just over half of the patients were taking other psychotropic drugs. Nevertheless the results of this open study are consistent with those of controlled studies in which sertraline was effective and well tolerated, in acute and continuation treatment for major depression, at 50 mg/day in most patients.

Abstract
We retrospectively analyzed the effects of recombinant human growth hormone (rhGH) in a Belgian population of 36 short children with renal allografts. Seven children were dropped from the growth study: 1 had skeletal dysplasia and in 6 cases rhGH was given for less than 1 yr (1 died, 1 developed genu valgum, 2 were non-compliant and 2 grafts deteriorated). Final height was reached in 17 patients, and 12 children were still growing at the end of the study. Median height standard deviation score (SDS) in the 29 patients was -2.3 at the time of transplantation, and -2.7 when rhGH therapy was initiated. During rhGH therapy (median duration 3.2 yr, range 0.6-7.7 yr), height SDS increased by a mean of 0.4 per year, and bone maturation was not accelerated. Final height reached was 162.7 (149.0-169.5) cm (median SDS -1.8) in males and 151.0 (130.5-169.5) cm (median SDS -1.9) in females. Final height is significantly greater in males than females compared with a historical control group of untreated patients. Final height is within the parental target height range in 6 out of the 17 patients. The increase in height SDS in patients who were at an advanced stage of puberty (Tanner stages 4-5) when rhGH therapy was initiated exceeded our expectations (mean height gain 14.2 cm in boys and 10 cm in girls). In the cohort of 36 children, 4 patients developed an acute allograft rejection, all of whom had an underlying chronic rejection. This resulted in 3 graft losses within 5 yr. Our results indicate that rhGH treatment has a positive effect in short children with renal allografts, even if it is started in late puberty. In the presence of underlying chronic rejection, rhGH treatment needs careful monitoring to minimize the risk of graft loss.

Abstract
To determine the risk factors predictive of graft loss from chronic rejection in pediatric renal allograft recipients, we reviewed the collaborative study database of the Société de Néphrologie Pédiatrique which registered 314 grafts from January 1987 to December 1991. Of the 289 grafts analyzed, 71 failed during follow-up, chronic rejection being the most common cause of graft loss (35%). The clinical features of the chronic rejection group (n = 25) were compared with those of the group without failure (n = 218). The variables tested by monovariate analysis were cyclosporine dose at 1 year, donor type, donor and recipient age, and acute rejection episodes. The incidence of graft loss due to chronic rejection was 4% (4/109) in patients who had no acute rejection and 16% (21/134) in those with at least one acute rejection episode (P = 0.002). Donor age (< or = 5 years) was a risk factor for chronic rejection (P = 0.024). Recipient age and donor type were not significantly different between the chronic rejection group and the control group. Using time-dependent covariates, the risk factors were an acute rejection episode (P = 0.003) and low cyclosporine doses at 1 year (P = 0.02). We conclude that acute rejection and low cyclosporine doses in these pediatric patients were risk factors for graft loss due to chronic rejection.

Abstract
UNLABELLED The aim of this study was to compare findings on coronary intravascular ultrasound and thallium-201 SPECT in patients following orthotopic heart transplantation. BACKGROUND No data are available on whether pathological thallium scintigraphic findings in heart recipients are based on coronary vessel wall alterations identifiable by intravascular ultrasound. METHODS 29 patients (mean age: 50.9 +/- 11.5 years; male n = 23) were investigated by means of intravascular ultrasound of selected coronary segments and thallium-201 myocardial SPECT. Patients were investigated 11.6 +/- 5.4 weeks post transplantation, a subgroup of 13 patients was re-investigated 70.2 +/- 18.4 weeks following transplantation. A total of 214 cross-sectional areas of the left coronary artery were examined using a 3.5 French intravascular ultrasound catheter to measure intimal index and the circumferential extension of a three-layer appearance of the vessel wall. Shortly after catheterisation, an ergometric stress-test was performed to examine all recipients by means of thallium-201 SPECT. In each patient, 20 segments of the left ventricle were evaluated using a score system of differentiate between persistent defects, redistribution, and reverse redistribution. A score was developed that measured the degree of inhomogeneity and severity of perfusion defects, respectively. Findings on scintigraphy were correlated to coronary intravascular ultrasound findings. RESULTS At first investigation, mean intimal index of all evaluated coronary cross-sectional areas was 0.06 +/- 0.1. Sixty-four cross-sectional areas demonstrated a three-layer appearance of the vessel wall, mean circumferential extension was 72 +/- 122 degrees. Thallium scintigraphy demonstrated a total of 336 (40%) pathological left ventricular segments; 168 (20%) were regarded as permanent defects, 67 (8%) demonstrated redistribution and 101 (12%) showed reverse redistribution. The score of inhomogeneity was calculated as 5.8% +/- 2.6%. In the subgroup of patients at the follow-up study, the score was 6.4 +/- 2.8%. There was no correlation between intimal index and the score, nor could any correlation be confirmed between the score and the circumferential extension of a three-layer appearance of the vessel wall. At second investigation, no significant differences of intimal index (0.05 +/- 0.07) or circumferential extension of a three-layer appearance of the vessel wall (74 +/- 118 degrees) could be confirmed. The score was slightly, but significantly increased to 8.1 +/- 4.5% at the second investigation (P < 0.05). CONCLUSION Early after orthotopic heart transplantation, pathologic thallium distribution patterns of the left ventricle could be observed. These pathological patterns did not correlate with the extent of diffuse coronary vessel wall alterations identifiable by intravascular ultrasound. After more than 1 year, the degree of scintigraphic abnormalities increased significantly, not accompanied by an increase of diffuse coronary vessel wall alterations.

Abstract
30 patients (mean age 51.4 +/- 11.6 years; female n = 6) were studied early after orthotopic heart transplantation (11.6 +/- 5.5 weeks). Twelve recipients had undergone specific treatment for biopsy proven rejection. Using a mechanical intravascular ultrasound device (3.5-F catheter), 153 coronary artery segments (16 left coronary main stem, 122 left anterior descending artery, 15 left circumflex artery) were studied. Intimal index and circumferential extension of a three-layer appearance of the vessel wall were assessed. In all segments, systolic-diastolic changes in area (delta A) with respect to vessel area and pressure (delta P) were used to study normalized compliance (normalized compliance = [delta A/A]/delta P [mm Hg-1 x 10(3)]). Intravascular ultrasound findings were correlated to perioperative ischemia time, LDL/HDL-ratio, Lp(a) and donor age. In a subgroup of 13 recipients, intravascular ultrasound investigation was repeated after an interval of 67.4 +/- 10.2 weeks. At first investigation, mean intimal index of all coronary segments was 0.07 +/- 0.10. Mean circumferential extension of a three-layer appearance of the vessel wall was 84 +/- 112 degrees. Normalized compliance was 2.43 +/- 1.90 mm Hg-1 in the left main stem 2.45 +/- 1.47 mm Hg-1 within the left anterior descending artery, and 2.66 +/- 1.72 mm Hg-1 within the circumflex artery (differences n.s.). No correlation was found between intimal index and normalized compliance (r = -0.322), nor between circumferential extension of intimal thickening and normalized compliance (r = -0.362). Furthermore, there was no correlation between normalized compliance and donor age. Normalized compliance was significantly lower in recipients with proven rejection than in those without (1.76 +/- 0.81 versus 2.95 +/- 1.22 mm Hg-1, p = 0.005). Both, intimal index and circumferential extension of intimal thickening, were significantly higher in recipients following rejection periods (p < 0.05). The extent of coronary vessel wall alterations on ultrasound correlated to donor age but not to perioperative ischemia time, LDL/HDL-ratio and Lp(a). Re-investigation of a subgroup of 13 recipients 67.4 +/- 10.2 weeks after the first study showed an insignificant increase of the intimal index (from 0.03 to 0.09) and of the circumferential extension of intimal thickening (from 40 to 111 degrees). Normalized compliance changed from 2.53 +/- 1.48 to 2.87 +/- 1.33 mm Hg-1 (differences n.s.). Early after orthotopic heart transplantation, a significant correlation between atherosclerotic coronary vessel wall alterations assessed by intravascular ultrasound and donor age can be confirmed. Heart recipients following rejection periods present with significantly more atherosclerotic vessel wall alterations and a severely reduced compliance of the coronary vessels.

Abstract
Granulomatous slack skin disease (GSS) is a rare disorder characterized by bulky cutaneous lesions and epithelioid and giant cell granulomas with destruction of the dermal elastic tissue. We detail the observation of a 29-year-old man with clinical and histological features of GSS. Pendulous skin tumors were associated with typical clinical and immunohistochemical aspects of mycosis fungoides and with clonal rearrangement of the V gamma T-cell receptor gene in lesional skin. This case report supports cutaneous T-cell lymphoma as a cause of GSS.

Abstract
In three patients with end-stage renal failure due to primary hyperoxaluria type 1, successful combined liver-kidney transplantation enabled us to assess the insoluble oxalate pool, which was compared with the histopathological changes observed in iliac crest biopsy specimens. Good correlation was observed between the histopathological grade of bone oxalosis and the estimated oxalate content of the body. In the end-stage of oxalate bone disease, hyperparathyroidism does not play a significant role in bone resorption, which appears to be the consequence of the granulomatous reaction induced by oxalate deposition. Combined liver-kidney transplantation should be performed long before this stage. Early hepatorenal grafting in uremia secondary to primary hyperoxaluria type 1 would avoid the deleterious clinical consequences of systemic oxalosis and shorten the duration of postransplant hyperoxaluria, which may compromise the course of kidney graft.

Abstract
Among development abnormalities of the upper urinary tract, ureteral duplication is a very common finding while triplication is quite rare. Ureteral quadruplication is exceedingly unusual; to our knowledge only three cases have been reported over the past 25 years and all of them concerned adult patients. We present a case of unilateral quadruplicated ureters in a 9-month-old infant. Review of the literature failed to reveal documentation of such a case.

Abstract
We report a case of congenital, bilateral absence of the internal carotid artery accompanied by a complex anastomotic plexus arising from the right maxillary artery, a terminal branch of the external carotid artery. We present the clinical features and the radiological diagnostic evidence which consisted of ultrasonography, brain CT and MRI, conventional angiography and skull base CT scan. We review the literature pertaining to this congenital anomaly and correlate embryology of the carotid arteries to this unusual type of collateral circulation.

Abstract
The "Gregg phenomenon" implies that myocardial function and oxygen consumption (MVO2) increase when coronary perfusion is enhanced within or above the autoregulatory range. We have recently demonstrated that the "Gregg phenomenon" has no significance for regional myocardial function and MVO2 in anesthetized swine in situ. There is, however, some evidence that the "Gregg phenomenon" may exist within stunned myocardium. To test whether coronary hyperperfusion increases regional myocardial function and MVO2 in stunned myocardium, in six anesthetized swine the left anterior descending coronary artery (LAD) was cannulated and perfused at constant pressure (CAP) using an extracorporal circuit. The coronary vein which parallels the LAD was cannulated to allow measurement of regional MVO2 and regional systolic wall thickening (WT%) of the anterior myocardium was assessed using sonomicrometry. Blood flow (CBF) to the LAD was increased by increasing CAP within the extracorporal circuit or by intracoronary adenosine infusion (150 micrograms/min). In normal myocardium, increasing CBF from 71.4 +/- 19.7 (SD) to 156.7 +/- 48.8 ml/min/100 g by increasing CAP from 100 +/- 10 to 190 +/- 10 mm Hg or increasing CBF from 75.1 +/- 29.1 to 189.2 +/- 45.8 ml/min/100 g by intracoronary adenosine infusion did not increase WT% (34.3 +/- 12.2% vs 32.1 +/- 10.6% and 32.3 +/- 10.7% vs 30.1 +/- 13.2%, respectively). MVO2 was not changed during enhanced CAP (6.94 +/- 1.05 vs 8.10 +/- 1.08 ml/min/100 g) and during intracoronary adenosine infusion (6.67 +/- 1.45 vs 7.30 +/- 2.23 ml/min/100 g). Twenty min of hypoperfusion followed by 30 min of reperfusion depressed WT% by 47% (p less than 0.05). However, MVO2 was only decreased by 23% (NS). In the stunned myocardium, increasing CBF from 62.1 +/- 36.4 to 157.1 +/- 60.0 ml/min by increasing CAP was not associated with an increase in WT%. MVO2, however, increased from 5.14 +/- 1.07 to 8.88 +/- 1.83 ml/min/100 g (p less than 0.05). Comparable results were achieved when CBF was increased from 60.3 +/- 28.7 to 176.9 +/- 48.5 ml/min by intracoronary adenosine infusion. WT% was unaffected, while MVO2 increased from 4.69 +/- 0.92 to 9.46 +/- 3.39 ml/min/100 g (p less than 0.05). Thus, increasing coronary perfusion within or above the autoregulatory range increases MVO2 in stunned myocardium, but without a simultaneous increase in regional myocardial function.

Abstract
In three cases of acute disseminated toxoplasmosis developing soon after renal (two patients) or hepatorenal (one patient) transplantation, Toxoplasma gondii trophozoites were visualized on Giemsa-stained smears of bronchoalveolar lavage fluid. Trophozoites were also found in bone marrow smears in one instance. Seroconversion occurred late in two cases and was not detected before the patient's death in the third. These observations underline the potential of bronchoalveolar lavage as a diagnostic procedure for disseminated toxoplasmosis.

Abstract
A rapidly enlarging left inguinal adenitis, with positive groove sign, and fever, chills, malaise, hypotension, headache, scarlatiniform rash, choleroid diarrhea, and proteinuria developed in an homosexual man who was positive for human immunodeficiency virus. The needle aspiration of the inguinal mass showed group A beta-hemolytic streptococci and the blood cultures were negative, suggesting group A streptococcal cellulitis-adenitis with toxic strep syndrome. Treatment with penicillin and surgical drainage was successful. Bacterial infections associated with defective humoral immunity appear to be common in patients with acquired immunodeficiency syndrome (AIDS), and some of these infections have a remarkable extensive and lethal evolution. Therefore streptococcal adenitis should be considered in any patient with AIDS or AIDS-related syndrome in whom rapidly enlarging inguinal nodes develop.

Abstract
We retrospectively studied the clinical, serological, bacteriological and histopathological data obtained in 6 HIV seropositive patients seen in our department from 1986 to 1989 for secondary syphilis. The clinical presentation was atypical in 4 of the 6 patients, with 2 palmoplantar keratodermas and 2 ulcerative syphilids. The diagnosis was made on darkfield examination in 2 patients, high titers of antibodies in 6 and histopathological examination (numerous plasma cells) in 4. All were cured with the classical penicillin therapy recommended for early syphilis.

Abstract
Endoscopic correction of vesicoureteral reflux in children has been increasingly used in the last years with encouraging results. During a 4-year period 152 children were treated by endoscopic injection of Teflon. A follow-up, ranging from 3 months to 5 years, was available for 173 refluxing ureters. For primary reflux, correction was observed after a single injection in 87% of the cases and in 93% after a second injection in some failures. In duplication, the technique is somewhat more difficult but the results quite satisfactory with 58% success after one injection, increasing to 74% after a second injection. The limitations of these techniques are underlined, the major concern being the safety of the injectable Teflon particles, eliciting a foreign-body granulomatous reaction with the potential hazard of distant migration. So far no long-term morbidity and complications have been observed with the use of Teflon to correct reflux. Extensive pathological study in 7 children submitted to ureteral reimplantation for failure of endoscopic correction showed a typical encapsulated granulomatous reaction below the intramural ureter, but particles of Teflon were noted in only one hypogastric ganglion when the Teflon was injected outside of the bladder. There is a need for finding an ideal substance for endoscopic injection, preferably prepared from the patient's own tissue allowing simple and safe correction of vesicoureteral reflux in children.

Abstract
The integration of colleagues from psychosocial occupations into the traditional team of doctors and nurses demands a holistic treatment concept, the general desire for interdisciplinary action, and readiness for patience in the process of mutual learning. The acceptance of the psychosocial services by the patient and his/her family is frequently determined by the acceptance by physicians and nurses. The members of the psychosocial team are confronted with the following tasks.: 1. Developing a trustful relationship with the patient and his/her parents, 2. Setting up a history of family dynamics, 3. Practical assistance in matters of hospital routines, 4. Assistance in the emotional aspects of coping with the disease, 5. Rendering support to a patient and his/her family at death, 6. Leading and moderating groups of parents who live with so called "residual fear" or are mourning a child. Colleagues of the psychosocial team, who have to be able to cope with these existentially demanding tasks within a relationship to patients and their families over an extended period of time should have sufficient professional identity, adequate professional competence, and a certain foundation of life experience.

Abstract
The success of FES exercise programmes for training paraplegic muscles at home depends highly upon the availability of reliable, easy-to-use and inexpensive training equipment. For endurance training, FES bicycle exercisers are well accepted. However, they are not suited for home use due to the high expense of commercially available equipment. This paper describes the development of a FES exercise bicycle for use at home. It consists of a standard bicycle ergometer with minimum modifications. The exerciser can be used by the patient sitting in the wheelchair, and may be used with any two-channel muscle stimulator.

Abstract
A patient with congenital chloride diarrhoea (CCD) is reported. The diagnosis on the 5th day of life was based on the watery stools with characteristic ionic composition. The neonate presented with abdominal distension necessitating laparotomy on day 1, followed by transverse colostomy on day 3, owing to persistent abdominal swelling. Total parenteral nutrition (from 1 to 3 months) followed by an enteral semi-elemental diet (from 3 to 5 months) was required to reduce the quantity of stools and to obtain a satisfactory nutritional state. The colostomy was closed at 16 months. Growth, psychomotor development and renal function are normal at 6 years. Criteria for therapeutic evaluation are discussed.

Abstract
A 26-year-old woman had a chronic vesiculopustular and ulcerating skin disease associated with fever and arthritis. Cutaneous biopsy specimens showed an extensive infiltration of the dermis and epidermis by neutrophils. Direct immunofluorescence (IF) revealed linear subcorneal IgA deposits. Indirect IF showed IgA antibodies reactive with the subcorneal zone of normal epidermis. The disease responded to dapsone therapy. The association between neutrophilic dermatoses, including pyoderma gangrenosum, subcorneal pustular dermatosis, and related entities, and IgA involvement, either IgA gammopathies and/or intraepidermal IgA deposits, is emphasized. Intraepidermal IgA deposits are possibly involved in the pathogenesis of our patient's condition and of other cases of unusual neutrophilic dermatoses.
