Assessing Family Functioning Before and After an Integrated Multidisciplinary Family Treatment for Adolescents With Restrictive Eating Disorders

Introduction

Previous studies applying the Lausanne Trilogue Play (LTPc), a semi-structured method for observing family dynamics, highlighted dysfunctional interaction patterns in the families of individuals affected by restrictive eating disorders (REDs). Family-centered approaches are considered the first-line treatment for severe cases of REDs in adolescence.

Objectives

To investigate family functioning in the families of adolescents with severe REDs assessed before and 6 months after a multidisciplinary family treatment program that combined psychodynamic psychotherapy, parental role intervention and triadic or family-centered intervention.

Methods

Sixty-seven families of adolescent patients diagnosed with REDs were assessed for eligibility between July 2017 and October 2020. Family functioning was assessed using the clinical version of LTPc. Nutritional counseling and neuropsychiatric monitoring were also provided.

Results

We observed a significant change in the family functioning score for the LTPc phase 2, in which the father interacts with his daughter while the mother acts as a silent observer. This suggests that the fathers, when playing an active role, could improve dyadic family functioning. The treatment was not found to change triadic functioning: a 6-month treatment may not be long enough to modify interactions at the triadic level.

Conclusions

A brief multidisciplinary treatment program may significantly improve family functioning in the families of patients diagnosed with severe REDs. Although appropriate clinical trials are needed to further test the efficacy of this treatment, our study reinforce the concept that treatment programs targeting the individual patient and both the parents should be a first-line approach in adolescents with severe REDs.

Peripheral inflammation exacerbates α-synuclein toxicity and neuropathology in Parkinson's models

AIMS

Parkinson's disease and related disorders are devastating neurodegenerative pathologies. Since α-synuclein was identified as a main component of Lewy bodies and neurites, efforts have been made to clarify the pathogenic mechanisms of α-synuclein's detrimental effects. α-synuclein oligomers are the most harmful species and may recruit and activate glial cells. Inflammation is emerging as a bridge between genetic susceptibility and environmental factors co-fostering Parkinson's disease. However, direct evidence linking inflammation to the harmful activities of α-synuclein oligomers or to the Parkinson's disease behavioural phenotype is lacking.

METHODS

To clarify whether neuroinflammation influences Parkinson's disease pathogenesis, we developed: (i) a 'double-hit' approach in C57BL/6 naive mice where peripherally administered lipopolysaccharides were followed by intracerebroventricular injection of an inactive oligomer dose; (ii) a transgenic 'double-hit' model where lipopolysaccharides were given to A53T α-synuclein transgenic Parkinson's disease mice.

RESULTS

Lipopolysaccharides induced a long-lasting neuroinflammatory response which facilitated the detrimental cognitive activities of oligomers. LPS-activated microglia and astrocytes responded differently to the oligomers with microglia activating further and acquiring a pro-inflammatory M1 phenotype, while astrocytes atrophied. In the transgenic 'double-hit' A53T mouse model, lipopolysaccharides aggravated cognitive deficits and increased microgliosis. Again, astrocytes responded differently to the double challenge. These findings indicate that peripherally induced neuroinflammation potentiates the α-synuclein oligomer's actions and aggravates cognitive deficits in A53T mice.

CONCLUSIONS

The fine management of both peripheral and central inflammation may offer a promising therapeutic approach to prevent or slow down some behavioural aspects in α-synucleinopathies.

Cost of a population-based programme of chest x-ray screening for lung cancer

BACKGROUND

After the implementation of a population-based programme of chest x-ray (CXR) screening on smokers in Varese, Italy, lung cancer (LC) mortality was significantly reduced. Analysis of the incremental costs due to this type of screening programme is needed to evaluate its economic impact on the healthcare system.

METHODS

In July 1997 a population-based cohort, consisting of all high-risk smokers (n=5,815) identified among 60,000 adult residents from the Varese province, was invited to a LC screening programme (an annual CXR for five years) in a general practice setting, and was observed through 2006. Invitees received National Health Service (NHS) usual care, with the addition of CXRs in screening participants. At the end of observation, among the 245 LCs diagnosed in the entire screening-invited cohort the observed LC deaths were 38 fewer than expected. To estimate the incremental direct cost due to screening in the invited cohort for the period July 1997-2006, we compared the direct cost of screening administration, CXR screens and LC management in the invited cohort and in the uninvited and unscreened controls in NHS usual care setting.

RESULTS

Over the 9.5 years, the total incremental direct healthcare costs (including screening organization/administration, CXR screens, additional procedures prompted by false-positive tests, overdiagnosed LCs) were estimated to range from euro 607,440 to euro 618,370 (in euros as of 2012), equating to between euro 15,985- euro 16,273 per patient out of the 38 LC deaths averted.

CONCLUSIONS

In a general practice setting, the incremental cost for a CXR screening programme targeted at all high-risk smokers in a population of 60,000 adults was estimated to be about euro 65,000 per annum, approx. euro 16,000 for each LC death averted.

Cost of reproduction. Changes in metabolism and endosulfan lethality caused by reproductive behavior in Hyalella curvispina (Crustacea: Amphipoda)

Biocides are periodically applied in agricultural activities, reaching aquatic systems and acting upon the biota. Amphipods are widely used in toxicity tests because of their sensitivity to a wide range of pollutants. In this work, we report the differential lethality of a widely used pesticide, endosulfan, on the amphipod Hyalella curvispina at two life stages and in three different adult groups, males and females separated by sex and both sexes grouped together. In addition, oxygen consumption of adult groups was determined as a way to estimate the role of behavioral activities and exposure to endosulfan in metabolism shifts. There were no differences between the LC(50) of juveniles and the adults when they were separated by sex (p>0.05). Nevertheless, the LC(50) of adults without sexual differentiation was significantly lower than the LC(50) of juveniles and adults separated by sex (p<0.05). The oxygen consumption rate was higher when adults were grouped without sexual differentiation in the control group. The exposure to low concentrations of endosulfan causes an increase in oxygen consumption in all the treatments. The sexual behavior increased the metabolism and the sensitivity to endosulfan. In future evaluations, adults grouped without sexual differentiation, which were the most sensitive group, should be included in order to mimic the environmental conditions. Using only juveniles or adults separated by sex in toxicity tests may inaccurately estimate the lethality of biocides, especially in species with constant reproductive activities.

Bullous lung disease and neurofibromatosis type-1

Lung interstitial diseases and bullae are described as possible complications of neurofibromatosis type-1 (NF-1), a genetic disorder inherited as a autosomal-dominant trait. We report the case of a 16-year-old male non-smoker with NF-1, who presented with pneumothorax caused by ruptured lung bullae. The case of this young patient, successfully treated by video-assisted thoracoscopic resection of bullae, supports the concept that pulmonary alterations may be part of the NF-1 syndrome, rather than as an unrelated complication.

Fasting hyperglycaemia and in-hospital mortality in elderly population

BACKGROUND

Admission hyperglycaemia has shown to be a marker of poor clinical outcome. The prevalence of admission hyperglycaemia and its relationship with in-hospital mortality in elderly population has not been clearly defined. We assessed the prevalence and prognostic significance of admission fasting hyperglycaemia in aged patients.

METHODS

A total of 808 elderly patients were studied. Patients were classified into group I (serum glucose < 126 mg/dl), II (126-180 mg/dl) and III (> 180 mg/dl). Groups II and III were considered newly recognised fasting hyperglycaemia (NRFH) in non-diabetic patients.

RESULTS

NRFH was present in 18.6%. After excluding diabetic patients (n = 206, 25.5%), the distribution of patients (n = 602, 74.5%) was as follows: group I (n = 452, 55.9%), group II (n = 122, 15.1%) and group III (n = 28, 3.5%). In the whole cohort, median fasting glucose was lower in patients who survived [105 mg/dl (88-135)] than in those who died [127 mg/dl (93-159), p < 0.001]. This significant difference was maintained only when non-diabetic patients were considered [100 mg/dl (87-122) vs. 118 mg/dl (92-149), p < 0.001]. In-hospital mortality rate in groups I, II and III was 8.5%, 14.1% and 22.9%, respectively (p < 0.001). Mortality rate was 8.4%, 18.0% and 32.1% (p < 0.001) in groups I, II and III, respectively in non-diabetic population. Both low albumin and high glucose serum concentrations were the only independent risk factors for in-hospital all-cause mortality in non-diabetic patients.

CONCLUSIONS

In non-diabetic elderly patients admitted for acute disease, serum glucose concentration is an important, simple and independent predictor of hospital mortality.

[Atrial fibrillation and thyroid nodules]

Our previous papers reported an association between atrial fibrillation and supracentimeter thyroid nodules. Recently we noticed that the number of patients admitted to our ward presenting this relationship, was higher than average data relating to whole world's population. In this study we tried to prove the existence of this association in a selected group of inpatients aged between 71 and 80. This to rule-out any age-related confounding factor. We enrolled one hundred inpatients, aged between 71-80. Each patient underwent TSH, FT3, FT4 determination, ECG and thyroid ultrasound examination. 55 males and 45 females: 25 with atrial fibrillation (group A) and 75 without atrial fibrillation (group B). In group A, 80% had supracentimeter thyroid nodules, whereas in group B, only the 6.7% showed supracentimeter thyroid nodules. The rate of supracentimeter thyroid nodules in inpatients without atrial fibrillation (group B) was in line with that found in many studies about whole world's population (4-10%). On the contrary, subjects with atrial fibrillation (group A) showed a rate of supracentimeter thyroid nodules significantly higher (p < 0.001). These findings confirm our previous studies even in more age homogeneous peoples. Moreover, they suggest a link between atrial fibrillation and thyroid nodules. Cytokines and growth factors (IGF-1, EGF, FGF) might act like a connection between nodule goitre and atrial fibrillation.

[Celiac disease and myelodysplastic syndrome. A case report]

Celiac disease is an immune-mediated disorder induced by the intake of gluten proteins involving primarily the gastrointestinal tract. Myelodysplastic syndromes are clonal hematologic disorders, expanded from myeloid stem cells of uncertain pathogenesis. Anaemia is a common finding in patients with celiac disease. Frequently it is secondary to malabsorption of iron, folic acid or vitamin B12 and usually disappears completely with a strict adherence to a gluten-free diet and supplement of deficient factors. To the best of our knowledge, in medical literature only two cases of myelodysplastic syndrome associated with celiac disease have been described. Here we describe the case of a patient affected by adult celiac disease who went into remission following a gluten free diet. Later a macrocytic anaemia without vitamin B12 or folate deficiency appeared. Hematologic tests showed findings consistent with refractory anemia with ring sideroblasts. The association of celiac disease with myelodysplastic syndromes seems not to be casual. It raises the hypothesis of a primitive immunological disorder in both diseases.

Non-thyroidal illness syndrome and short-term survival in a hospitalised older population

BACKGROUND

non-thyroidal illness syndrome (NTIS) has been associated with an adverse clinical outcome.

OBJECTIVE

to evaluate the prevalence of NTIS, its impact on patients' survival and the possible pathogenic role of systemic inflammation.

DESIGN

observational cross-sectional analysis.

PARTICIPANTS AND SETTING

three hundred and one acutely ill older patients (156 women; median age 81 years, range 65-101) consecutively admitted to a primary care unit.

METHODS

serum FT(3), FT(4) and thyrotropin levels as well as acute inflammation indexes were evaluated.

RESULTS

the NTIS prevalence (specifically low T3 syndrome) was 31.9%. A significant association was found between NTIS and acute renal failure (P = 0.006), New York Heart Association classification (NYHA) IV heart failure (P = 0.003) and metastasised cancer disease (P = 0.0002). Serum FT(3) values correlated inversely with serum C-reactive protein (P < 0.0001), lactate dehydrogenase (P = 0.0004), fibrinogen (P = 0.03) and erythrocyte sedimentation rate (P < 0.0001) values, and progressively decreased with increasing tertiles of age (P = 0.0004). The mortality rate was significantly higher (P = 0.0002) among patients with low T3 syndrome, which emerged as the sole predictive factor of death (odds ratio 4.3; 95% confidence interval 1.7-10.5).

CONCLUSIONS

low T3 syndrome is very common in the hospitalised older population, emerging as the most sensitive independent predictor of short-term survival. Serum FT(3) determination should be included in the assessment of short-term prognosis of acutely ill older patients.

[Pure red cell anaemia secondary to medullary B cell chronic lymphoproliferative disorders. A rare case]

Acquired erythroblastopenia is rather rare, more frequent in adult or old male. In absence of anti EPO antibody, it's associate to inhibition of the erythroid growth mediated by suppressive T lymphocytes, generally T8 or NK or mediated by IgG antibody in association with timoma, lymphoproliferative or immunological disorders, and other diseases. The course usually is chronic and follows that of the associate pathology. We report a case with pure red cell anaemia associated to non classified medullary B cell lymphoproliferative disorder in an old woman with complete remission after steroid therapy.

[Low T3 syndrome and left ventricular diastolic function]

BACKGROUND

Recent data suggest that low triiodothyronine (T3) syndrome may contribute to the pathophysiology of cardiac diseases. Because the development of diastolic dysfunction occurs early in a failing heart, we evaluated whether patients with low T3 syndrome show abnormalities in diastolic function, also in absence of overt cardiovascular disease.

METHODS

Thirty-four patients with low T3 syndrome and 34 controls with normal levels of free T3 (FT3) underwent a complete Doppler echocardiographic examination. Criteria of exclusion from the study were the presence of cardiovascular disease or traditional cardiovascular risk factors, a primitive thyroid disease, cachexia, and the use of drugs affecting the thyroid function.

RESULTS

Patients with low T3 syndrome, if compared with controls, show evidence of left ventricular diastolic dysfunction, documented by prolongation of the isovolumic relaxation time (120 vs 75 ms, p < 0.0001) and a reduction in the early diastolic mitral flow velocity/late diastolic mitral flow velocity ratio (0.66 vs 2.05, p < 0.0001), mainly due to the increased A-wave (0.96 vs 0.40 m/s, p < 0.0001). These alterations increase proportionally with FT3 reduction.

CONCLUSIONS

Patients with low T3 syndrome show evidence of impaired left ventricular relaxation. Doppler echocardiography may be a useful non-invasive technique for the assessment of diastolic performance in these patients.

Amylase: A disease activity index in multiple myeloma?

This study reports a case of a patient with lambda-light chain multiple myeloma who developed a high hyperamylasaemia of the salivary type during the disease and soon afterwards died. Ectopic production of amylase by myeloma cells has been described in a few cases and demonstrated by tissue culture and immunohistochemical techniques. The common characteristics of these cases were: salivary amylase isoenzyme increase, high tumor mass, extensive extra-medullary spread, extensive bone destruction and poor prognosis. In patients with amylase-producing multiple myeloma, the onset of hyperamylasaemia heralds a rapid disease progression; therefore, in these patients, a simple test such as serum amylase may represent a reliable disease activity index and provide an additional prognostic information.

[Hypokalemia from ectopic ACTH secretion and hypothiroidism in patient affected by small cell lung cancer]

Endocrin paraneoplastic syndromes are characterized by an ectopic hormonal production. The ectopic adrenocorticotropic hormone (ACTH) secretion is often associated with small cell lung cancer. We report the case of 64-years-old man with persistent hypokalemia in Cushing's syndrome due to ectopic ACTH secretion. The patient was affected by small cell lung cancer and presented an hypothiroidism too. A proper chemotherapy resulted in remission of the hypokalemia, but the hypothiroidism was not influenced during our observation period.

[Abdominal ultrasound features in heart failure]

Heart failure involves many organs and systems. Because of heart failure is one of the most common admission diagnosis in a Medical Ward, we sought their abdominal ultrasound features in addition to the cardiac ones.

[NT-proBNP in elderly inpatients: an useful marker for detecting heart failure?]

In this study we try to determine a cut off for detecting heart failure (HF) with the highest sensitivity and specificity in a population of hospitalized people aged > or = 65 years and to identify potential confounding variables for the interpretation of plasma concentration of the marker. We evaluated 212 consecutive patients admitted to our Department of Medicine, the only inclusion criterion being an age > or = 65 years. We identified a group with clinical and/or instrumental HF, and among remaining patients we selected a normal group without obvious cardiac disease. The strongest predictors of higher levels of NT-proBNP resulted age and free-triiodothyronine as in all models they were strongly associated with Log NT-proBNP. Using receiver-operating characteristics (ROC) curves, we found an optimal discriminatory value for detecting HF in 879 pg/ml for subjects aged between 65 and 74 years and 1658 pg/ml for subjects aged > or = 75 years. In elderly hospitalized patients the discriminatory cut offs of NT-proBNP for the diagnosis of HF are significantly higher than community derived reference values. Adjustments for the independent effects of age and other confounding variables appear necessary.

[Venous thromboembolism risk in medical inpatients]

Venous thromboembolism is one of the main causes of morbidity and mortality in many diseases, either in medical or in surgical wards. The aim of this study is to determine its frequency in a medical ward and to find all the patients who need a prophylaxys. We examined all the inpatients admitted in our Department during a period of three years, selecting all subjects affected by venous thromboembolism. Patients affected by metastatic cancer, namely pancreatic one, or congestive heart failure showed higher risk to develope venous thromboembolism. A prompt heparinic prophylaxys could reduce thromboembolic events. Male gender could be a further risk factor.

Relationship between serum uric acid levels and urinary albumin excretion in patients with heart failure

OBJECTIVES

Hyperuricaemia is a constant finding in patients with heart failure (HF). Upregulated xanthine-oxidase activity seems to contribute to progression of the disease through the production of oxidative stress and the development of vascular and endothelial dysfunction. On this basis we speculated that in HF serum uric acid levels correlated with a reliable marker of endothelial dysfunction as urinary albumin excretion.

METHODS

Fifty-three patients with HF underwent assessment of serum uric acid, N-terminal probrain natriuretic peptide (NT-proBNP), glomerular filtration rate (GFR), other metabolic parameters and determination of urinary albumin concentration (UAC) in a morning urine sample.

RESULTS

In univariate analysis there is a direct correlation between serum uric acid levels and log UAC (r = 0.43, P < 0.01); uric acid correlates also positively with log NT-proBNP (r = 0.31, P < 0.05) and negatively with log-GFR (r = -0.38, P < 0.01). In stepwise regression analysis serum uric acid emerged as the only predictor of increased UAC (standardized coefficient = 0.42, P = 0.001) independent of other clinical determinants and metabolic factors.

CONCLUSION

Serum uric acid represents the strongest predictor of elevated UAC in HF. Regression of albuminuria may be a simple target to verify the efficacy of xanthine-oxidase inhibition in these patients.

[New therapeutic strategies to the advanced non small cell lung cancer]

Lung cancer is an elevated mortality disease in spite of conventional therapy. Today it is possible to identify some molecules, as the epidermal growth factor receptor, involved in the earliest molecular alterations ofcancerogenesis. Here we show the inhibitors of the epidermal growth factor receptor as a therapeutic mean.

[Serum uric acid levels correlate with left ventricular ejection fraction and systolic pulmonary artery pressure in patients with heart failure]

The aim of this study was to elucidate whether in patients with heart failure (HF) serum uric acid (UA) levels correlated with left ventricular ejection fraction (LVEF) and systolic pulmonary artery pressure (SPAP). Fifty consecutive patients with heart failure underwent serum (UA) determination and echocardiographic examination, with measurement of LVEF and SPAP. Twenty healthy age-matched subjects served as controls. Mean serum UA in patients with HF were significantly higher that in controls (7.5 +/- 0.3 vs 4.5 +/- 0.3 mg/dl, P < 0.0001). In patients group serum UA correlated negatively with LVEF (R = -0.45, P < 0.01) and positively with SPAP (R = 0.51, P < 0.001); these relations persist in a multivariable regression analysis, after adjustment for other variables potentially confounding (P = 0.031 and P = 0.003, respectively). In patients with HF, serum UA correlates with LVEF and SPAP independently from other clinical determinants, supporting the possibility that the detection of progressive hyperuricemia in these patients may be an indicator of deteriorating cardiac function.

[Clinical differences between heart failure versus ischemic patients]

Heart failure represents a very common disease with high mortality, despite therapeutic and preventive measures. In order to evaluate the characteristics of heart failure patients, a case-control study was carried out, comparing sixty heart failure patients versus sixty patients who presented an evident atherosclerotic disease, but not heart failure. Among the differences we found, a higher heart rate, reduced levels of free-triiodothyronine and increased levels of serum uric acid in heart failure patients might directly contribute to its pathophysiology and represent potential therapeutic targets.

[Incidence of thyroid nodules in patients with and without atrial fibrillation]

In one of our previous articles we noted that many patients affected by atrial fibrillation had more thyroid nodules > or = 10mm (38%) than general population (10%). These data are confirmed by a same number of patients without atrial fibrillation admitted to our Department of Internal Medicine. The high incidence of low-T3 syndrome is confirmed too.

[Extramedullary hematopoyesis: compensatory mechanism or clinic syndrome? Case report and review of literature]

Extramedullary hematopoiesis (EMH) is a compensatory mechanism occurring in patients with chronic anemia. Liver, spleen, and lymph nodes are frequently involved. However, EMH may also develop in several sites such as thymus, kidneys, retroperitoneum, paravertebral areas of the thorax, lungs, bowel and others. Rarely symptomatic, it often shows a variety of clinical features. This condition, frequently, may be fatal. A correct early diagnosis of EHM might avoid, if possible, a bad prognosis. The Authors report a case where bone marrow cells were identified in centrifuge cerebrospinal fluid of a patient suffering from non-Hodgkin lymphoma.

Systemic amyloidosis: a clinical challenge

This study reports a case of an 82-year-old white woman with a history of congestive heart failure refractory to diuretic therapy who was found to have systemic amyloidosis, confirmed by a rectal biopsy. Cardiac involvement by amyloid should be considered in the differential diagnosis of any patient with heart failure with preserved ventricular systolic function, who does not have evidence of ischaemic heart disease or hypertension. However, the rarity of this disease and the various involvement of different organs and tissues are often responsible for missed or delayed diagnosis. Systemic amyloidosis is a life-threatening disease but an early diagnosis may modify its course; therefore it is important to maintain a high clinical suspicion and to increase the awareness of this overlooked condition among clinicians.

Relationship between low T3 syndrome and NT-proBNP levels in non-cardiac patients

OBJECTIVES

A low T3 syndrome was described in patients with heart failure (HF), and it appears to be associated with adverse outcome, representing an independent predictor of mortality. However, it is not known if low T3 levels contribute to the pathophysiology of HF. On the other hand, it has been seen that an elevation of brain natriuretic peptides (BNP and NT-proBNP) may represent a warning signal for future cardiovascular disease and may be an early marker of diastolic dysfunction. Therefore we tested the hypothesis that low levels of free-triiodothyronine (FT3) are sufficient to determine an increased concentration of the amino-terminal fragment of pro-brain natriuretic peptide (NT-proBNP), as the result of an initial and asymptomatic cardiac impairment.

METHODS

A total of 52 consecutive non-cardiac patients underwent thyroid function profile evaluation and NT-proBNP determination. On the basis of FT3 values they were divided in two subgroups: a low T3 group (19 patients) and a normal T3 group (33 patients).

RESULTS

The median NT-proBNP concentration of patients with low T3 syndrome was significantly higher than in those with normal FT3 (370 vs. 120 pg/ml, P = 0.002). There is a strong and inverse correlation between FT3 and Log NT-proBNP (R = -0.47, P < 0.001); this relation persists in a multivariable regression analysis, after adjustment for other potentially confounding variables (P = 0.008).

CONCLUSION

In absence of overt cardiovascular disease, patients with low T3 syndrome present an increased concentration of NT-proBNP. These data suggest that low FT3 levels may be a contributing factor for the development of cardiac dysfunction.

[Heart failure and cholelithiasis]

We previously found an high incidence of gallstone or cholecystectomy for lithiasis in patients affected by heart failure (52.1% up to 58.6%). As in general population the incidence of this disease is up to 38%, we tried to explain our findings.

[Atrial fibrillation and thyroid gland]

Many diseases can lead to atrial fibrillation and one of these is thyroid disfunction. The prevalence of atrial fibrillation does not differ between subclinical and overt hyperthyroidism. Hypothyroidism also can be associated to atrial fibrillation. Low-T3 syndrome is considered a risk factor in cardiac patients. In 100 patients affected by atrial fibrillation we studied the thyroid function and performed ultrasound examination of the thyroid gland. 30 patients had a low-T3 syndrome, 66 (38 > or =10 mm) patients had thyroid nodules, while just 10 patients had an abnormal thyroid function. So, in patients affected by atrial fibrillation, we suggest to study the levels of thyroid hormones and, even if these are normal, to perform an ultrasound examination of the gland.

Visceral leishmaniasis in a patient treated for polyarteritis nodosa

We report a case of visceral leishmaniasis in a patient receiving steroids and cyclophosphamide for polyarteritis nodosa. The clinical presentation of leishmaniasis, with fever, pancitopenia and hypergammaglobulinemia may be confused with a reactivation of vasculitis or with other non-infectious conditions such as haematologic diseases. In endemic areas, the case of latent leishmaniasis must be considered and serology for Leishmania should be performed before starting immunosuppressive treatment.

[Continence problems after radical prostatectomy: medical treatment]

OBJECTIVE

We hypothesized that a benefit can be obtained from both urine storage and urethral resistance after retropubic radical prostatectomy through the induction of artificial erections.

MATERIAL AND METHODS

From January 1993 to December 2000 we have submitted 127 patients to radical retropubic prostatectomy. According to preoperative bladder behaviour, 59 patients (46.5%) presented voiding disorders, 10 (7.9%) filling disorders, 4 (3.1%) mixed disorders, whereas 54 (42.5%) were asymptomatic. The urethral catheter was removed between the 10th and the 12th postoperative day. Fourteen patients entered a programme of early sexual rehabilitation with intracavernous injection of prostaglandin E1 (ICI) within 7 days from catheter removal.

RESULTS

After catheter removal the recovery of urinary continence occurred within 2.2 +/- 2.3 days. At dismissal from the hospital, 8 patients (6.2%) were almost totally incontinent; 2 (1.5%) were still incontinent after a 6-month period; 73 (57.4%) were dismissed with clinical signs of detrusor instability hence treated with anticholinergic drugs such oxybutynin or tolterodine; 3 (2.3%) resulted obstructed after surgery because of stenosis of the anastomosis. Almost all the patients submitted to early sexual rehabilitation referred an improvement of their incontinence after the first injection. The patients who did not begin an early sexual rehabilitation generally recovered from incontinence in a longer time.

CONCLUSIONS

Our preliminary observations showed that artificial erection PGE1-induced is effective in improving or accelerating post radical prostatectomy incontinence recovery. The results apply also to patients with pre-operatory detrusor instability.

[Endoscopic surgery in day hospital using bladder and urethral anesthesia with EMDA]

PURPOSE

To assess the suitability of EMDA local anaesthesia for invasive procedures on lower urinary tract in one day surgery treatment.

PATIENTS AND METHODS

The deep penetration of lignocaine into the bladder wall was attained by catheters, electrodes and electric current generators using revised electrochemical principles. Since 1994 203 patients with transitional cell carcinoma of the bladder underwent TURBT and 70 patients with bladder neck or prostatic obstruction underwent TURP, TUIP, TULAP; 20 patients underwent miscellaneous procedures: in 34 patients the procedures were combined. The patients' age was within 20 and 90 years (mean age 67.3). The procedures were performed in a single small endoscopic theatre annexed to the Urology Ward. A standard rigid resectoscope was used as well as a standard electrocautery (360 kHz) or a mega frequency low temperature Vesalius generator (4 MHz). Most patients received a premedication and some of them a light sedation when necessary, but all of them were fully conscious and able to complete an assessment using a simple pain scale.

RESULTS

8 out of 273 patients (3%) considered pain intolerable and other 11 (4%) reported painful but tolerable sensation, and the remaining 254 patients referred absent or minimal discomfort. Most of the patients were able to walk back to their room and go home in the evening. Those who had no chance of going back home were admitted for the night as well as those who had no assistance at all at home or those who had high probability of haemorrhage. Side effects were minimal and not related to local anesthesia: the serum lignocaine levels measured in 4 patients were innocuous. All patients experienced some tingling and reddening at the skin site of the dispersive electrode fading in a few hours.

CONCLUSIONS

Local anaesthesia by using EMDA proved to be effective for most invasive endoscopic procedures in the lower urinary tract and suitable for patients undergoing day hospital surgery.

[Amyotrophic lateral sclerosis in a patient with Waldenstrom's macroglobulinemia]

Although a peripheral neuropathy is the best known neurological complication of Waldenstrom's Macroglobulinemia (WM), the association of Amyotrophic Lateral Sclerosis (ALS), or other Motor Neuron Diseases (MND) with monoclonal gammopathies is described. We report the case of a male patient (41 years old) with WM and ALS. Whether monoclonal gammopathies play a role in the pathogenesis of MND is unclear but is la possible that patients might have antibodies against motor neurons. In our reported case neurologic symptoms were the first and the most important manifestations of the underlying hemopathy and despite plasmapheresis and immunosuppressive treatment ALS syndrome progressed. The neurologic disease worsened despite the improvement of WM.

Low prevalence of islet autoantibodies in patients with gestational diabetes mellitus

OBJECTIVE

To determine the proportion of patients with gestational diabetes mellitus (GDM) who have serological characteristics typical of IDDM.

RESEARCH DESIGN AND METHODS

Islet cell antibodies (ICAs), insulin autoantibodies (IAAs), GAD65, and IA-2 antibodies were measured in 145 pregnant women with GDM, 33 with impaired glucose tolerance (IGT), and in 73 with normal glucose tolerance (NGT). ICAs were measured by indirect immunofluorescence; GAD65 and IA-2 antibodies, by a radio-ligand immunoassay incorporating 35S-labeled recombinant antigen; and IAAs, by a liquid-phase radiobinding assay.

RESULTS

The prevalences of islet autoantibodies were low and not significantly different between groups. ICAs were detected at levels ranging from 5 to 45 Juvenile Diabetes Foundation U in 14 (10%) women with GDM, 2 (6%) women with (GT, and in 4 (5%) women with NGT. IAAs were detected at levels between 3 and 4 SD above the mean in 4 (3%) women with GDM, 0 women with IGT, and in 1 (1%) woman with NGT. None had both ICAs and IAAs. Neither GAD65 nor IA-2 antibodies, which have been detected in the majority of pre-IDDM and IDDM patients, were found in NGT, IGT, or GDM patients.

CONCLUSIONS

Low-titer ICAs and IAAs are not infrequent in pregnant women, but multiple islet autoantibodies and antibodies to GAD65 or IA-2 were not found in GDM. These findings suggest that the serological characteristics of IDDM are rare in GDM.

Insulin antibodies do not preclude optimization of metabolic control in women with IDDM during pregnancy

OBJECTIVE

To evaluate whether the presence of insulin antibodies (IAs) may preclude the optimization of metabolic control during pregnancy and affect outcome in women with IDDM.

RESEARCH DESIGN AND METHODS

IAs were measured by radiobinding assay in 44 women with IDDM referred to the Diabetes and Pregnancy Outpatients' Clinic during 46 pregnancies. Age, duration of IDDM, metabolic control (HbA1c, mean pre- and postprandial capillary blood glucose, frequency of hypo- or hyperglycemia), insulin requirement at 1st and 3rd trimester of pregnancy, BM1, and weight gain were recorded. Neonatal variables such as gestational age, weight, length, and the presence at birth of either hypoglycemia, hypocalcemia, or jaundice requiring phototherapy were also considered.

RESULTS

IAs correlated positively with insulin requirement (P < 0.05) and negatively with HbA1c at term (P < 0.01). Patients with IA levels > or = 40% insulin binding (8 of 46) had a higher insulin requirement and lower preprandial capillary blood glucose at the beginning of pregnancy but not at term (P < 0.005), whereas they had lower HbA1c at term than did patients with low IA levels (P < 0.01). IA levels decreased slightly at term (P = 0.007). IA levels > or = 40% were not associated with a higher rate of hypo- or hyperglycemic episodes or with diabetic complications or thyreopathy. No correlation was found between 1A levels and any of the neonatal variables considered.

CONCLUSIONS

The presence of IAs does not preclude optimization of metabolic control during pregnancy and is compatible with a favourable outcome.

Glutathione conjugation with 1-chloro-2,4-dinitrobenzene (CDNB): interindividual variability in human liver, lung, kidney and intestine

The rate of glutathione conjugation with 1-chloro-2,4-dinitrobenzene (CDNB) was measured in specimens of human liver (n = 93), sigmoid colon (n = 56), renal cortex (n = 67) and lung (n = 68). In the liver there was a weak but significant (r = - 0.247 p = 0.017) negative correlation between the activity of glutathione transferase and the liver donor's age. Such a correlation was not found in the renal cortex, lung and colon. In the renal cortex and in lung the rate of glutathione conjugation with CDNB was a little but significantly (p < 0.05) higher in women than men, whereas no sex-dependent difference was observed in the liver and colon. The distribution of glutathione transferase activity was polymorphic in the mucosa of colon and renal cortex of men but not in that of women. Smoking seems not to affect the glutathione conjugation rate with CDNB in lung. The activity of glutathione transferase was 2-, 6-, and 7-fold greater in liver than in the renal cortex, lung and colon, respectively. There was a large interindividual variability of the hepatic glutathione transferase activity, and because this variability, 15% of the population studied catalyzed the glutathione conjugation with CDNB at a rate similar to those of the renal cortex and duodenum. The subjects with low expression of the hepatic glutathione transferase should be more exposed to the effects of toxic and carcinogenic compounds.
