[Responsibility for prescribing and monitoring an act transfusion and safety blood transfusion]

The act to transfuse is a prescription following basic rules similar to drug prescriptions. If harm happens, potentially linked with this prescription, the harm's responsibility is borne by the physician, the paramedics, the care organization but by the supplier laboratory too. The setting of good practice rules consistent with science data at the time when the act is performed, the respect of the patient's rights and the quality of supplied products will be assessed during the expertise. Under restorative responsibility, it is necessary to previously establish a direct and certain causation between the litigious act and the harm to enforce the vicarious liability. Nowadays, legal precedents grant a larger protection to more and more numerous victims, enhancing the field of the fault with the appeal to assumption of fault. At the same time, the lawmaker himself promulgated objective conditions of compensation for many categories of victims of medical risk from which transfused people are part. The law of March the 4th of 2002 went one step closer devoting a new foundation of compensation: national solidarity.

Serum uric acid and its relationship with metabolic syndrome and cardiovascular risk profile in patients with hypertension: insights from the I-DEMAND study

BACKGROUND AND AIMS

The independent role of serum uric acid (SUA) as a marker of cardio-renal risk is debated. The aim of this study was to assess the relationship between SUA, metabolic syndrome (MS), and other cardiovascular (CV) risk factors in an Italian population of hypertensive patients with a high prevalence of diabetes.

METHODS AND RESULTS

A total of 2429 patients (mean age 62 ± 11 years) among those enrolled in the I-DEMAND study were stratified on the basis of SUA gender specific quartiles. MS was defined according to the NCEP-ATP III criteria, chronic kidney disease (CKD) as an estimated GFR (CKD-Epi) <60 ml/min/1.73 m(2) or as the presence of microalbuminuria (albumin-to-creatinine ratio ≥2.5 mg/mmol in men and ≥3.5 mg/mmol in women). The prevalence of MS, CKD, and positive history for CV events was 72%, 43%, and 20%, respectively. SUA levels correlated with the presence of MS, its components, signs of renal damage and worse CV risk profile. Multivariate logistic regression analysis revealed that SUA was associated with a positive history of CV events and high Framingham risk score even after adjusting for MS and its components (OR 1.10, 95% CI 1.03-1.18; P = 0.0060; OR 1.28, 95% CI 1.15-1.42; P < 0.0001). These associations were stronger in patients without diabetes and with normal renal function.

CONCLUSIONS

Mild hyperuricemia is a strong, independent marker of MS and high cardio-renal risk profile in hypertensive patients under specialist care. Intervention trials are needed to investigate whether the reduction of SUA levels favorably impacts outcome in patients at high CV risk.

[Fatal hemorrhage in postpartum by rupture of a splenic artery aneurysm]

The maternal mortality is rare and when it arises, the family often puts the medical profession in guilty's position. We present the case of a 38-year-old woman, died in the post-partum in a context of intense back pains. The autopsy found an incidental hemorrhagic syndrome to a two-stage rupture of the splenic artery. We shall discuss the aetiology. The autopsy and the anatomopathological examination are practiced only in hardly more than a quarter of the cases while they will be important in proceedings and will allow the family to go into mourning.

3D CT scan study of fetal cranial base: interests of occipital bone measurements in age estimation

OBJECTIVES

Cranial base development during fetal life is of major interest for many research purposes. In this study, we focused on fetal age estimations which are extremely important in forensic contexts. Nevertheless, there have been very few studies using occipital measurements to determine fetal age.

OBJECTIVES

To evaluate change in the sagittal length/maximum width ratio of the basilar part of the occipital bone and to propose a simple and reliable method for fetal age determination.

METHODS

A sample of 30 male and 7 female fetuses aged 24 to 41 weeks amenorrhea underwent CT scan. Occipital bones were reconstructed (Amira 4.0) and measurements were carried out on each part.

RESULTS

A multivariate analysis (ANOVA) gave an age formula using right exoccipital measurements and a linear regression supplied the age of reversion of the sagittal length/maximum width ratio.

CONCLUSION

This preliminary study clearly highlighted the promises of 3D CT-Scan studies of fetal cranial base and gave interesting results and the method deserves to be tested on a larger sample.

Blood pressure control in the Hypertension in the Very Elderly Trial (HYVET)

To report blood pressure control in the Hypertension in the Very Elderly Trial, a placebo-controlled trial of hypertensive (systolic blood pressure (SBP) 160-199 mm Hg, diastolic blood pressure (DBP) <110 mm Hg) participants over the age of 80 years, given treatment in three steps: indapamide slow release 1.5 mg alone, indapamide plus 2 mg perindopril and indapamide plus 4 mg perindopril. The difference in control between participants with combined systolic and diastolic hypertension (SDH, DBP90 mm Hg) and those with isolated systolic hypertension (ISH, DBP<90 mm Hg) is determined together with the effects of increments in the treatment regimen. At 2 years, the active treatment lowered blood pressure by 16.5/6.9 mm Hg more than that on placebo in participants with SDH and by 19.3/4.8 mm Hg more in those with ISH. The 2-year falls in pressure on placebo alone were 13.2/8.5 mm Hg in SDH and 8.2/1.5 mm Hg in ISH participants. With full titration of active treatment, 62% of SDH participants achieved goal SBP (<150 mm Hg) by 2 years and 71% of those with ISH. The corresponding results for DBP control (<80 mm Hg) were 40 and 78%. The addition of active perindopril 2 mg roughly doubled the percentage controlled, as did increasing to 4 from 2 mg. Blood pressure control was good with ISH and better than with SDH. The fall in SBP accounted for the observed 30% reduction in strokes, but the 21% reduction in total mortality and 64% reduction in heart failure were greater than predicted.

Medication misuse and abuse: duties and responsibilities of dispensing pharmacists

Misuse of medications can have major consequences for the consumer or patient's health. In the case of a drug delivered only on medical prescription, the misuse usually results from an error or negligence on the part of the prescribing doctor and/or the pharmacist dispensing the medication. But whereas, under French Law, doctors are regularly prosecuted for their irresponsibility, pharmacists frequently avoid any legal charges. This is even more surprising in view of the fact that French Legislation controls the practice of pharmacy very strictly. The authors discuss four cases that illustrate this issue and present a study of comparative pharmaceutical law requirements.

Verapamil and propranolol: a comparison of two antihypertensive agents

Verapamil, a calcium antagonist, was compared with propranolol, a widely used beta-adrenoreceptor blocker, in hypertensive patients with respect to its antihypertensive efficacy and incidence and severity of adverse effects. Both drugs caused similar blood pressure reductions without interfering with pulse pressure. The hypotensive effect of verapamil was not accompanied by any effect on heart rate, while after propranolol there was a significant bradycardia. ST-segment and T wave abnormalities at rest and after exercise were partially or completely reverted by both drugs. The incidence and severity of adverse effects was very low and no patient was withdrawn from the study because of complaints due to the active drugs. Verapamil can be compared as antihypertensive drug to the beta-blocker propranolol and this may justify, together with the absence of negative effects on lipids, blood sugar, serum electrolytes and renal function, its use as an antihypertensive drug of first choice.

[Cervico-thoracic liposarcoma in an HIV patient]

Association between cervico-thoracic liposarcoma and HIV infection is uncommon. The etiopathology remains unclear and clinical symptoms can be various, often not very evident or absolutely absent. Preoperative diagnosis is based on modern imaging techniques. In selected cases, the ideal procedure is surgical treatment which allows good long-term results. A case of cervico-thoracic liposarcoma in HIV patient is presented.

[Integrated treatment of breast cancer: review of our experience]

In the industrialized West countries the breast cancer represents the most frequent malignant neoplasia in the women. From over 30 years we have a progressive increase of frequency of breast carcinoma. Mortality is substantially unchanged. The Authors, on the base of casuistry accumulated in five years of activity, trace a diagnostic-therapeutic run to the purpose to favour a line of behavior, practice and actual, for the management of breast cancer.

[Endoscopic resection of a gastric haemangioma: case report]

Gastric haemangiomas are an infrequent histological type of gastrointestinal benign tumors. Diagnosis is based on imaging but only pathological examination can give certainty. Endoscopic resection, according some specific criteria, is the gold standard procedure. Authors present a case of cavernous haemangioma diagnosed and treated by endoscopic procedure.

Fatal occupational inhalation of hydrogen sulfide

A young man aged 22 years, a sewer worker by profession, died after massive inhalation of hydrogen sulfide while at work. He was rescued by the emergency services and admitted to the critical care department, where he died due to massive myocardial necrosis less than 24 h after admission. In this case, where the causes of the accident were not clearly established, autopsy and anatomopathologic examination made it possible to confirm the causal lesions which resulted in death and to question the initial version of the circumstances of the accident. Medicolegal investigation was valuable in determining possible liabilities and repercussions on coverage as an industrial accident by the national health insurance system.

An anthropometric study of relationships between the clival angle and craniofacial measurements in adult human skulls

STATING BACKGROUND: The clival angle, between the ethmoidal plane and the clival plane, measures the cranial base angulation. Relations between cranial base angulation and facial patterns have been discussed and present contradictory evidence. The aim of this study is to determine whether correlations could be found between the clival angle and craniofacial measurements.

METHODS

This study was carried out on a sample of 235 human skulls. Twenty landmarks were marked. The clival angle and 16 other variables were measured and compared using analysis of variance.

RESULTS

Statistical analysis showed a relationship between the clival angle and six measurements (P < 0.05). There was a positive correlation between the clival angle and the cranial lengths, the nasomaxillary sagittal measurements and palatal length but the width of the foramen magnum had a negative correlation. No significant relationship was found between the clival angle and the cranial height and widths, the palatal width, the length of the foramen magnum and the mandibular measurements.

CONCLUSIONS

The trends found in this study with regard to the craniofacial lengths show that the nasomaxillary complex in humans has a stable position lying beneath the anterior cranial base. Transversal, vertical and mandibular variables have a more independent relationship.

Spigelian hernia: a case report and review of the literature

Spigelian hernia is a rare abdominal hernia that occurs through Spigelian aponeurosis. The Authors present a case of Spigelian hernia associated with narrowing of sigmoid colon and diverticular pathology. They also described historical background, surgical anatomy and etiopathogenesis of this hernia. By a remarkable revision of literature, they sum up epidemiology and clinical features of Spigelian hernia. Furthermore, they discuss diagnostic and therapeutic principles.

[Complications of the Lichtenstein inguinal hernioplasty]

The Lichtenstein inguinal hernioplasty in the original version or with small variations currently allows good results both from the surgical point of view and in terms of reduction of the sanitary expenses. "Tension free" repair and diffusion of local anesthesia allow a drastic reduction of the hospital stay, a early time of the working activity and the diffusion of the admission to the Day Hospital. The authors introduce the own casuistic that comprise 1116 inguinal hernioplasty in 1,034 patients and on the base of two studies, a retrospective one and another prospective, they conclude that a greater attention in the behavior of the intervention and a more accurate preparation of the patients represent fundamental moments to obtain even more satisfactory results.

[Leiomyosarcoma of brachiocephalic vein: case report]

Primary leiomyosarcoma of venous origin is a rare but frequently lethal disease. Clinical symptoms can be different, often not much evident or absolutely absent. Preoperative diagnosis is difficult also with modern imaging and only pathological examination can identify this malignant tumor. Successful therapy requires early surgery but the long-term survival is poor. A case of leiomyosarcoma arising from veins has been presented.

The court medical expert in France: changes in status

In France the status of the court expert has undergone a significant change with the adoption of statute no. 2004-130 of 11 February 2004 and its implementing regulations no. 2004-1463 of 23 December 2004. This article looks at the two most outstanding aspects of this change in status: (i) the conditions for registering on a court of appeal list and, (ii) the practical details of the quality control of the court expert's work as exercised by the judge. The article concludes with a brief comparison with the expert witness situation in England and Wales.

[The clinical significance of lymph node micrometastases and of concept of sentinel lymph node]

Micrometastases, (metastases smaller than 2 mm), had benn subject of several studies. In literature is documented a prognostic worsening due to their presence. Research of micrometastases in sentinel lymph node is of great interest and can allow a clinical application with profitable cost efficacy ratio. The Authors discuss about clinical, prognostical and therapeutical implicationes in case of micrometastases into sentinel lympho nodes.

A simple tool to predict exercise capacity of obese patients with ischaemic heart disease

OBJECTIVE

To define an equation that predicts exercise capacity taking into account body mass index (BMI).

DESIGN

Retrospective analysis and validation study of a multidisciplinary programme aimed at weight loss and physical rehabilitation.

SETTING

Tertiary referral hospital.

PATIENTS AND METHODS

372 consecutive obese participants (249 men) with stable ischaemic heart disease, aged mean 60.1 (SD 8.7) years, underwent a treadmill exercise test. BMI was 37.8 (4.5) kg/m(2). In the validation study the model was tested in 87 patients with similar characteristics.

RESULTS

Mean exercise intensity was 6.6 (SD 2.4) metabolic equivalents (METs). Multivariate linear regression analysis defined two simple models that considered exercise intensity as the dependent variable and a set of independent variables such as anthropometric measures, age and sex in the first one, plus associated clinical conditions and drug treatment in the second one. The correlation coefficients of the two models were R = 0.630 and R = 0.677, respectively. Age, BMI and sex were the strongest predictors of exercise capacity. The first derived equation efficiently predicted exercise capacity: in the validation study predicted exercise intensity was 6.3 (1.6) METs and attained exercise intensity was 6.3 (2.4) METs (p = 0.903) with a highly significant correlation (R = 0.534, p < 0.001).

CONCLUSION

BMI is an important determinant of exercise capacity of obese people with ischaemic heart disease. The use of a simple equation may help in predicting exercise capacity, in individualising exercise protocol and in setting up rehabilitation programs for obese patients.

The regional commission for medical accidents and nosocomial infections set up by French law

The regional commission for conciliation and compensation for medical accidents, iatrogenic diseases and nosocomial infections (commission régionale de conciliation et d'indemnisation des accidents médicaux, affections iatrogènes et infections nosocomiales, CRCI) offers victims of such events the possibility of obtaining compensation without recourse to legal proceedings. We suggest various points of view about this commission set up by the French law no. 2002-303 of 4 March 2002: the composition, role and competence of the CRCI; the place of the expert's report; the opinion pronounced by the CRCI and its outcome, the compensation of victims and, finally, interaction with other procedures.

Effects of nilvadipine and amlodipine in patients with mild to moderate essential hypertension: a double blind, prospective, randomised clinical trial

OBJECTIVE

This double blind, prospective, randomised, parallel group clinical trial was aimed at investigating the effects of nilvadipine or amlodipine in mild to moderate hypertensive patients over a 3-month treatment period.

RESEARCH DESIGN AND METHODS

Eligible outpatients (supine DBP > or = 90 mmHg and < or = 110 mmHg and supine SBP < or = 180 mmHg) entered a maximum 15-day placebo run-in period and were randomised to receive once daily nilvadipine 8 mg or amlodipine 5 mg (to be doubled in the case of lack of response at day 30). Follow-up visits with measurement of supine and orthostatic blood pressure and heart rate were performed after 15, 30, 60 and 90 days of treatment. Standard laboratory tests and 12-lead ECG were performed at study entry and at the end of treatment; adverse events were collected at any time.

RESULTS

A total number of 168 patients, 83 in the nilvadipine and 85 in the amlodipine group, took part in the study: 15 and 14 in the two groups, respectively, were prematurely withdrawn. Supine DBP at endpoint similarly decreases in the two groups (-11.0 +/- 7.1 mmHg in the nilvadipine group and -12.7 +/- 8.2 mmHg in the amlodipine group), with no significant differences between groups at any time point. Measurements in the orthostatic position also did not show between-groups differences. Blood pressure was normalised in 61.8% of patients in the nilvadipine group and in 63.0% in the amlodipine group; responders to therapy were 64.5% and 69.1% in the two groups, respectively. Results of SBP also did not show differences between groups at any time point, except a more marked decrease in the amlodipine group compared to nilvadipine in the supine measurements at endpoint. A total number of 30 patients (36.6%) in the nilvadipine group and 23 (27.1%) in the amlodipine group reported adverse events (p = 0.24 between groups), which mainly consisted of vasodilatory effects (e.g. oedema, flushing and headache). A favourable lipid profile, i.e. a significant (p = 0.002 between groups) decrease of triglycerides levels and an increase of HDL-C, was observed in the nilvadipine group, compared with an increase of triglycerides in the amlodipine group. No effects on haematology, liver and renal function were observed in either group.

CONCLUSIONS

Nilvadipine or amlodipine produced comparable effects on DBP and shared a similar adverse effect profile. A favourable effect on lipid profile was observed following nilvadipine treatment.

[Operative table-induced pressure ulcers]

The Authors conducted a study on 780 patients who underwent surgery. Fourteen patients developed operative table-induced pressure ulcers of different gravity. This paper is a description of these 14 cases. From the literature and from experience we know that the major exogenous risk factor for intraoperative pressure ulcers is the operation time. Therefore, special attention should be paid to preoperative, intraoperative and postoperative prevention. The knowledge of the pathology, specialized personnel and the use of appropriate facilities can reduce the risks of complication that are important sanitary and economic issue.

[Polypoid lesions of the gallbladder: diagnostic and therapeutic problems]

The nature of polypoid lesions of the gallbladder is difficult to define. Surgical indication still remains controversial but in some cases mandatory. In this clinical study data were retrospectively evaluated in 25 patients with polypoid lesions who underwent laparoscopic surgery to elucidate the ultrasonic findings and to establish criteria for the best treatment.

Large incisional hernia in the elderly: which kind of treatment?

Incisional hernia is one of the commonest long-term complications of open abdominal surgery. Especially in old patients (over 70 years), the incisional hernias represent an invalidating pathology whose treatment, for the high incidence of associated respiratory and cardiovascular disease, offers difficulties related to the preoperative and postoperative management as well as to the surgical treatment. This paper reports the Author's experience about the surgical treatment of large incisional hernia (> 10 cm) with open prosthetic mesh repair in geriatric patients.

Home blood pressure measurement and its relationship with blood pressure control in a large selected hypertensive population

Despite the impressive increase of home blood pressure monitoring (BPM) among hypertensive patients over the last few years, a limited number of studies have analysed the rate of home BPM and its relationship with target blood pressure (BP) control, in representative samples of the hypertensive population. The objectives of the study were first to evaluate the prevalence of home BPM in a large selected group of treated hypertensive patients referred to our outpatient hypertension hospital clinic. Second, to assess the rate of satisfactory clinic BP control in patients with or without familiarity with home BPM. In all, 1350 consecutive hypertensive patients who attended our hypertension centre during a period of 12 months and were regularly followed up by the same medical team were included in the study. After informed consent all patients underwent the following procedures: (1) accurate medical history (implemented by a structured questionnaire on demographic and clinical characteristics, including questions concerning home BPM); (2) physical examination; (3) clinic BP measurement; (4) routine examinations; and (5) standard 12-lead electrocardiogram. A total of 897 patients (66%) out of 1350 (687 men, 663 women, age 58.6 +/- 12.3 years, mean clinic BP 141 +/- 16/87 +/- 9 mmHg ) were regularly practising home BPM. In this group of patients, home BPM was associated with a significantly greater rate of satisfactory BP control (49.2 vs 45.6%, P < 0.01). Patients performing home BPM were more frequently men (54 vs 46%, P < 0.02 ) younger (average age 57.8 +/- 12.0 vs 60.3 +/- 12.7 years, P < 0.001) and with a higher educational level (defined by more than 8 years of school, 71 vs 55%, P < 0.05) than their counterparts. There were no significant differences in duration of hypertension, hypercholesterolaemia, obesity, smoking, diabetes, associated cardiovascular diseases, left ventricular hypertrophy and compliance with drug treatment. This study demonstrates that: (1) home BPM is widely performed by hypertensive patients managed in a hypertension hospital clinic; (2) this practice is associated with a significantly higher rate of clinic BP control; and (3) age, male gender and educational level influence the adoption of home BPM.

Effect of chronic treatment with beta-blockers on resting energy expenditure in obese hypertensive patients during a low-calorie and physical training program

BACKGROUND AND AIM

To evaluate whether chronic treatment with beta-blockers influences resting energy expenditure (REE) and weight loss after a period of diet and physical activity in obese hypertensive patients.

METHODS AND RESULTS

Seventy-eight obese hypertensive patients (24 males and 54 females) aged 53.7 +/- 11.1 years with mean BMI of 42.4 +/- 5.8 kg/m2 were enrolled. Thirty-eight patients were using beta-blockers while 40 patients who had not received beta-blockers in the past 6 months were the control group. REE was measured with indirect calorimetric method. Total body fat mass, total body fat-free mass (FFM) and total body water (W) were determined by bioelectrical impedance analysis. Patients and controls underwent a structured physical training program and a hypocaloric diet for a period of 31.6 +/- 10.6 days. Measured REE in patients taking beta-blockers was 1818 +/- 309 kcal/24 h and 1853 +/- 348 kcal/24 h in patients not taking beta-blockers; p = non significant. Weight and BMI loss were similar between the two groups and were respectively -6.43 +/- 2.62 kg and -2.42 +/- 0.91 kg/m2 in the beta-blocker group and -7.49 +/- 3.10 kg, -2.78 +/- 1.03 kg/m2 in the non beta-blocker group. Body composition was similar in the two groups. In the comparison between patients treated with selective beta 1-adrenoceptors blockers and non selective beta-blockers we found a significant difference in REE (1704 +/- 283 vs 1974 +/- 278; p = 0.012) and in weight loss (-5.6 +/- 2.4 vs -7.5 +/- 2.7; p = 0.048) at the end of study.

CONCLUSIONS

Beta-blockers are not associated with a lower REE in obese subjects compared to other antihypertensive treatment. Use of non selective beta-adrenergic blockers is associated with a higher REE and weight loss compared to use of selective beta 1-adrenergic blockers. Non selective beta-blockers could be indicated among first choice drugs in hypertensive severely obese subjects without contraindications to beta-blockade.

Awareness of hypertension guidelines in primary care: results of a regionwide survey in Italy

Unsatisfactory blood pressure (BP) control so often described in treated hypertensive populations is also explained by insufficient physicians' awareness of experts' guidelines. We assessed awareness of current recommendations about hypertension management in a general practice setting, using the World Health Organization/International Society of Hypertension (WHO/ISH) 1999 guidelines as reference. In a regionwide survey, a total of 5133 physicians (three-quarters of all active general practitioners in Lombardy, a region of north-western Italy) were contacted by letter and received a multiple choice 10-item questionnaire. Data on physicians' demographic characteristics, information on hypertension prevalence and their perception of BP control among their patients were also requested in an additional form. The number of answers in agreement with WHO/ISH guidelines was used as an awareness measure. This was considered adequate if correct answers to six out of 10 questions, including an appropriate definition of hypertension, were provided. Of the 1256 returned questionnaires (a 24.5% response rate), 1162 were suitable for analysis. The mean score of correct answers was 5.3 points and only 20.1% of the study population correctly answered at least six of the questions (including that on the definition of hypertension in the elderly). Guidelines awareness was negatively related to increase in physicians' age and duration of clinical practice and by the male gender. Finally, the physicians reported a high rate of achieved BP control, and those who were considered to have achieved highest rates (>75%) of control in their patients had a lower rate of adequate knowledge than those who reported less-successful therapeutic results (18 vs 25%, P<0.01), suggesting that they ignored or disregarded the goal BP recommended by the guidelines. This large regional survey shows that a sufficient degree of guidelines awareness is present in a minority of primary-care physicians in the Italian region of Lombardy. Therefore, further efforts are required to intensify information strategies for improving professional education, training and practice organization aimed at achieving therapeutic goals. Physicians with longer duration of clinical practice represent a particularly relevant target group for these interventions.

Three weekly injections (TWI) of low-dose growth hormone (GH) restore low normal circulating IGF-I concentrations and reverse cardiac abnormalities associated with adult onset GH deficiency (GHD)

GH replacement therapy given 3 times weekly (TWI) and adjusted to allow serum IGF-I concentrations in the mid-normal range for sex and age has been shown to be as effective as the daily regimen in improving lipid profile, body composition, bone mass and turnover in adult GH deficient (GHD) patients. Only one study has investigated so far the short-term (6 months) effect of a fixed weight-based TWI dosing schedule on heart structure and function in childhood onset (CO) GHD patients, whereas such a schedule in adult onset (AO) GHD patients has not been studied as yet. Aim of this study was to investigate whether a 1-yr low-dose titrated TWI GH-replacement regimen aimed at achieving and maintaining IGF-I levels within the low normal limits for age and sex is able to affect cardiovascular and heart parameters in a group of AO GHD patients. Eight adult patients (4 women and 4 men, age 35.8 +/- 3.37 yr, body mass index, BMI, 28.7 +/- 2.62 kg/m2) with AO GHD were included in the study, along with 10 healthy subjects, matched for age, sex, BMI and physical activity (6 women and 4 men, age 35.2 +/- 4.05 yr, BMI 28.4 +/- 2.34 kg/m2). M- and B- mode ecocardiography and pulsed doppler examination of transmitral flow were performed in GHD patients at baseline and after 3 and 12 months of GH therapy (mean GH dose 6.7 +/- 0.8 microg/kg/day given thrice a week), while normal subjects were studied once. Treatment with GH for 1 yr induced a significant increase in left ventricular (LV) diastolic and systolic volumes (+11.1 and +16.5%, respectively). Systolic LV posterior wall thickness and LV mass were increased (+10.2 and +7.7%, respectively) by GH administration. Systemic vascular resistance was significantly decreased by 1-yr GH therapy (-13.8% after 1 yr), while stroke volume, cardiac output and cardiac index were increased (+9.4, +11.6 and + 11.9%, respectively). LV end-systolic stress was decreased at the end of GH therapy (-11.2%). E and A wave, significantly reduced at baseline, were increased by 1 yr of GH therapy (+23.3% and +28.1%, respectively); likewise, the abnormally high E peak deceleration time was partially reversed by GH administration (-10.7%). Our study, though conducted in a small sample size, demonstrates that a TWI GH treatment schedule is able to reverse the cardiovascular abnormalities in AO GHD patients and to improve body composition and lipid profile. The maintenance of circulating IGF-I concentrations within the low normal range allows to avoid most of the side-effects reported with higher GH doses while being cost-effective and improving the patient's compliance.

Compliance to hypertension guidelines in clinical practice: a multicentre pilot study in Italy

The aim of this study was to investigate the diagnostic approach to recently diagnosed hypertensive patients by primary care physicians in Italy and to find out whether general practitioners manage these patients according to 1999 WHO/ISH guideline recommendations. In total, 228 consecutive patients (117 men and 111 women, mean age 51+/-12 years) with recently diagnosed hypertension (<2 years) referred for the first time to six outpatient hypertension centres throughout Italy were included in the study. The primary care physicians' approach was evaluated during the specialist visit by a specific questionnaire containing detailed questions about diagnostic work-up and treatment made at the time of the first diagnosis of hypertension. At the study visit, 71% of the patients were on treatment with antihypertensive drugs and 18.7% of them had blood pressure (BP) values lower than 140/90 mmHg. A complete clinical and laboratory evaluation according to the minimum work-up suggested by the guidelines had been carried out in only 10% of the patients. A full physical examination had been performed in 60% of the patients, electrocardiogram in 54%, serum total cholesterol in 53%, glucose in 49%, creatinine in 49%, urine analysis in 46%, potassium in 42%, and fundus oculi in 19%. Additional investigations such as ambulatory BP monitoring, echocardiogram, carotid ultrasonogram, and microalbuminuria had been carried out in a minority of patients (21, 18, 9, and 3%, respectively). The impact on hypertension guidelines on patients' management in everyday primary care practice appears marginal. Thus, our findings indicate that the majority of general practitioners manage hypertensive patients according to a simple BP-based approach rather than a more integrated approach based on global risk stratification.

[Use of abdominal wall retractor Laparo Tenser in gasless laparoscopic cholecystectomy]

High pressure CO2-peritoneum for laparoscopic surgery is not indicated in patients with impairment of cardiorespiratory and renal function and in high risk patients and in obesity. On the other site the uncontrolled abdominal insufflation and the blind insertion of the first trocar in patients with extended intraperitoneal adhesions, often cause bleeding and the intestinal loops dislocation, and can determine visceral lesions. In these patients gasless technique with an abdominal laparolifter can be employed. We report an experience of 36 patients undergoing laparoscopic cholecystectomy by a subcutaneous planar retractor. It was observed a good operative exposure in 83.3%; the surgery was safely performed in 88.8%. Two suprafascial hematoma related to the insertion of the needles of the Laparo Tenser occurred. A regular post-operative discharge was observed in 84.4%. These good results supports the extension of the laparoscopic approach for the cholecystectomy to complicated or to high risk patients.

Limits of the Lamendin method in age determination

This study shows that epithelial attachment level, used as age determination criterion in Lamendin's method, is not reliable for adults of either sex above the age of 49 years with periodontal diseases in any quadrant. The underestimation of calculated age increases from 7 to 19 years with chronological age. On the other hand, the present paper confirms the pertinence of dentin translucency as an age indicator in Lamendin's method.
