Neurological development and iron supplementation in healthy late-preterm neonates: a randomized double-blind controlled trial.

Late-preterm infants (LPT) are at increased risk for long-term neurodevelopmental sequelae and iron deficiency. The aim of the study is to assess the positive effect of iron supplementation on psychomotor development in healthy LPT. We designed a randomized placebo-controlled double-blind trial dividing the newborns into two groups. Every patient was assessed using the Griffiths Mental Development Scales (GMDS)-II edition at 12-month post-conceptional age. The study was performed at the Neonatology Unit of our Hospital, in Italy. Sixty-six healthy LPT infants born between 340/7 and 366/7 weeks of gestational age were enrolled in the study. One group received martial prophylaxis from the third week of life to 6 months of post-conceptional age (2 mg/kg/day of iron pidolate), the other received placebo. Fifty-two of the enrolled infants were assessed using the GMDS at 12-month of post-conceptional age. Statistical analysis of the mean scores of the Griffiths subscales was performed. There was a difference in the mean developmental quotient (DQ) (p < 0.01) between the two groups: iron group mean DQ 121.45 ± 10.53 vs placebo group mean DQ 113.25 ± 9.70. Moreover, mean scores of the Griffiths subscales A, B, and D showed significant differences between the two groups (scale A p < 0.05, scale B p < 0.02, scale D p < 0.01, respectively).Conclusions: We recommend that all LPT neonates receive iron supplementation during the first 6 months of life in order to improve their 1-year neurodevelopmental quotient. What is Known: • Late-preterm infants (LPT) are at increased risk for long-term neurodevelopmental sequelae and also for iron deficiency. • Iron deficiency is an independent risk factor for adverse neurological outcomes. What is New: • Healthy late-preterm who received iron supplementation during the first 6 months of life achieved better neurological outcomes at 12-month post-conceptional age than LPT who received placebo. • Our study strongly supports the need for the implementation of martial prophylaxis in LPT neonates.

Effects of orthodontic aligners on 24-hour masseter muscle activity: a multiple-day electromyographic study.

OBJECTIVE: This study aimed to assess the effects of aligners on masseter muscle activity by using an electromyographic device in the home environment. METHODS: The study was performed on healthy patients who required orthodontic treatment. Three different 24 h-EMG recording sessions were performed in different conditions: without aligners, with passive aligners, and with active aligners. The non-functional MMA work index (nfMMA-WI) and the non-functional MMA time index (nfMMA-TI) for both awake and sleep hours were assessed. ANOVA test was used to compare the average activity during the three recording conditions. RESULTS: On average, a total recording time of 204.7 ± 7.9 hours were provided for each patient. For most patients, ANOVA test showed an absence of significant differences between the recording sessions. CONCLUSIONS: The impact of our results is not negligible: clinicians can find remarkable support to the hypothesis that the use of aligners affects the MMA only in a minority of subjects.

RAGE gene polymorphism in heart failure patients with and without angiographic evidence of significant coronary atherosclerosis.

Heart failure (HF) is a multifactorial disorder in which clinical, environmental and genetic components take part. For this reason it is possible that common gene variants could affect development, progression and response to pharmacological therapy. In recent years the role of AGEs in the pathogenesis of cardiovascular diseases has become recognized but little is known about the role of the AGE–RAGE system in heart failure. The aim of the present study was to identify possible relationship between -374 T/A RAGE gene polymorphism with heart failure. The population in this study consists of 386 subjects with HF, selected according to the presence of depressed Left Ventricular Ejection Fraction (LVEF) less than45 percent, and 639 patients with CAD documented at coronary angiography. Within the population with HF there are 228 patients with disease secondary to not ischemic cause and 158 with post-ischemic condition. The sample of AA genotype was significantly lower in patients with post-ischemic HF in respect to HF secondary to non-ischemic causes (pless than0.001). A significant difference between the two groups was also observed regarding the allele frequency. In addition, differences in the allelic and the genotypic frequencies of homozygous genotypes were found between the HF patients free from evidence of coronary significant lesions and patients with at least one hemodynamically significant coronary lesion, both HF and CAD. In patients with at least one vessel compromised the presence of A allele and the homozygous AA genotype were significantly lower than in patients with lesion-free coronary. In conclusion, our research reveals that the -374 T/A polymorphism is related to the genesis of atherosclerotic coronary artery disease but not to its evolution. The protective role of AA genotype in respect to atheromatous disease is therefore confirmed also in the HF population with non-ischemic origin.

A newborn with ectrodactyly, tetralogy of Fallot, esophageal atresia, hypospadias and TP63 gene mutation: A new type of EEC Syndrome?

EEC syndrome is an autosomal dominant genetic disease with incomplete penetrance characterized by ectrodactyly, ectodermal dysplasia, and cleft lip/palate; these manifestations can differently occur in the affected subjects and can also be associated with other anomalies, such as in the urogenital tract.We reported the case of a newborn with prenatal diagnosis of EEC type 3 associated with severe cardiac abnormalities (Tetralogy of Fallot), high esophageal atresia with fistula and penoscrotal hypospadias.

Factors affecting consumers' preferences for and purchasing decisions regarding pasteurized and raw milk specialty cheeses.

Eight hundred ninety consumers at a local food festival were surveyed about their specialty cheese purchasing behavior and asked to taste and rate, through nonforced choice preference, 1 of 4 cheese pairs (Cheddar and Gouda) made from pasteurized and raw milks. The purpose of the survey was to examine consumers' responses to information on the safety of raw milk cheeses. The associated consumer test provided information about specialty cheese consumers' preferences and purchasing behavior. Half of the consumers tested were provided with cheese pairs that were identified as being made from unpasteurized and pasteurized milk. The other half evaluated samples that were identified only with random 3-digit codes. Overall, more consumers preferred the raw milk cheeses than the pasteurized milk cheeses. A larger portion of consumers indicated preferences for the raw milk cheese when the cheeses were labeled and thus they knew which samples were made from raw milk. Most of the consumers tested considered the raw milk cheeses to be less safe or did not know if raw milk cheeses were less safe. After being informed that the raw milk cheeses were produced by a process approved by the FDA (i.e., 60-d ripening), most consumers with concerns stated that they believed raw milk cheeses to be safe. When marketing cheese made from raw milk, producers should inform consumers that raw milk cheese is produced by an FDA-approved process.

Clinical study on the effects of a cosmetic product on dermal extracellular matrix components using a high-resolution multiphoton tomograph.

BACKGROUND/PURPOSE: The aim of this study was to demonstrate the effects of selected plant extracts in a cosmetic cream on the dermal network components after a 3-month treatment using an in vivo multiphoton tomographic device. METHODS: Twenty-four Caucasian women aged between 45 and 65 applied randomly a cosmetic emulsion B containing active ingredients (soy and jasmine) twice a day on one arm and its vehicle A (without active ingredients) on the other arm during 3 months. Measurements were performed on the internal side of the forearm before starting the treatment (T0), after 4 week (T4) and 12 weeks (T12) treatment. Measurements consisted of a multi-layers acquisitions using a multiphoton tomograph with subcellular resolution. Optical sections (about 6 microm thick) were recorded from 0 to about 200 microm using two different wavelengths: 760 and 820 nm. To compare the series of images and obtain an objective quantification of the signal of second harmonic generation (SHG) and autofluorescence, the method used consisted of taking the integrated brightness of an image (same rectangular area for all images) as a measure of the signal. Following this step, a ratio between brightness of images from the area treated with cream A or B and brightness of untreated area was calculated and used as an assessment of treatment efficacy. The parameter used for statistical analysis (variance analysis) is the difference before and after 12 weeks of treatment by either cream A or B of the signal ratios calculated in the upper dermis (118-130 microm) and those from a deeper region of the upper dermis (165-178 microm). RESULTS: Signals (autofluorescence+SHG) of extracellular matrix do not change significantly with time (weeks 0, 4 and 12) when cream A (vehicle with no active ingredient) is applied. Treatment with cream B results in an enhancement in the signal level of extracellular matrix at week 12. The comparison of signals, in both areas (118-130 microm and 160-178 microm), show an higher increase in the deeper region than in the more superficial one for product B while we do not notice any change with product A. CONCLUSION: The multiphoton tomograph provided excellent high-resolution images, which describe clearly the different skin layers, single cells and extracellular matrix components in all the 24 volunteers. Statistic analyses reveal a real effect for product B with selected plant extracts, known to increase collagen synthesis. Changes observed are characteristics of modifications in dermal collagen and elastin content. To our knowledge, it is the first time that it was possible to demonstrate in vivo the effect of a cosmetic product on the superficial dermal layer, in a non-invasive and non-destructive process, i.e. without cutting the skin.

Measurement of 14MeV neutron-induced prompt gamma-ray spectra from 15 elements found in cargo containers.

Within the EURopean Illicit TRAfficking Countermeasures Kit (EURITRACK) project, the gamma-ray spectra produced in a series of materials by 14-MeV tagged-neutron beams have been collected in the inspection portal equipped with large volume NaI(Tl) detectors, in order to build a database of signatures for various elements: C, N, O, Na, Al, Si, Cl, K, Ca, Cr, Fe, Ni, Cu, Zn, Pb. The measured spectra have been compared with prediction from Monte Carlo simulations to verify the consistency of the relevant nuclear data inputs. This library of measured 14-MeV neutron-induced gamma-ray spectra is currently used in a data processing algorithm to unfold the energy spectra of the transported goods into elementary contributions, thus allowing material identification.

Serum pseudouridine as a biochemical marker in the development of AKR mouse lymphoma.

Pseudouridine is a modified nucleoside derived from the degradation of some species of RNA, primarily transfer RNA, the level of which is elevated in biological fluids of tumor-bearing subjects. In order to study the relationship between pseudouridine levels and the development and progression of neoplasia, we have measured pseudouridine levels in the serum of inbred mice with high (AKR) and low (BALB/c) incidence of spontaneous lymphoma and in mice carrying transplantable lymphoid tumors. Our results show that the serum level of pseudouridine: (a) in healthy mice, is higher in females than in males; (b) increases significantly in female AKR mice in the period preceding the development of lymphoma (preneoplastic period occurring at about 6 months of age); and (c) is highest in AKR mice with lymphoma, the most elevated levels being found in mice with widely disseminated disease. The latter observation was confirmed by experiments with a transplantable AKR lymphoma (T2), where a positive correlation between tumor burden and serum pseudouridine levels was found. On the contrary, in BALB/c mice carrying a transplantable myeloma tumor (MOPC-460), no increase was seen despite the presence of a considerable tumor burden. The increase of pseudouridine in the preneoplastic period, in the absence of overt disease is viewed as an early sign of the development of the disease.

Nitric oxide modulation of neutrophil-endothelium interaction: difference between arterial and venous coronary bypass grafts.

OBJECTIVES: This study sought to evaluate the relation between the pattern of neutrophil-endothelial adhesion in saphenous vein (SV) and internal mammary artery (IMA) grafts and the endothelial production of nitric oxide (NO). BACKGROUND: Autologous IMA and SV grafts (SVGs) are increasingly used as conduits for coronary bypass grafting. Previous studies have demonstrated a greater production of endothelial-derived relaxing factor (NO) from IMA than from SVGs. Because of the well known role of NO in modulating the adhesion of polymorphonuclear leukocytes to the endothelium, we studied the pattern of neutrophil adhesion to the endothelium of IMA and SVs under basal conditions and after inhibition of NO synthesis. METHODS: Segments of IMA and SVs were obtained from 20 patients undergoing coronary artery bypass graft surgery. We evaluated the adhesion of both unstimulated and activated neutrophils to the endothelial surface of IMA and SVs in both basal conditions and after inhibition of NO synthesis with Nomega-nitro-L-arginine methyl ester. RESULTS: Under basal conditions, no difference in unstimulated neutrophil adhesion to endothelium was observed between the two vessel conduits. After neutrophil activation, a significantly (p < 0.05) greater adhesion of neutrophils was observed in the SV than in the IMA. After inhibition of NO release, the adhesion of activated neutrophils increased in both vessels, and no significant difference between them was observed. The increased adhesion was attenuated by both L-arginine and sodium nitroprusside. CONCLUSIONS: The lesser neutrophil adhesion to the endothelium of the IMA is a consequence of enhanced release of NO at this level; this effect could be responsible for the better early and long-term patency of this conduit over the SVG in coronary bypass grafting.

Common carotid arterial wall thickness in NIDDM subjects.

OBJECTIVE: To verify whether carotid arterial intimal plus media thickness (IMT) is greater in non-insulin-dependent diabetes mellitus (NIDDM) subjects, known to be at high risk for atherosclerosis. Evidence is growing that IMT is increased in subjects with coronary heart disease (CHD) risk factors like hypercholesterolemia and cigarette smoking. RESEARCH DESIGN AND METHODS: Fifty-four NIDDM subjects and 54 sex- and age-matched control subjects underwent CHD risk factors assessment and echo-Doppler examination of carotid arteries. IMT was measured by computer technique in the common carotid artery (CCA). Presence of plaques and/or stenosis (carotid atherosclerosis [CA]) was also evaluated by a single-blinded reader. RESULTS: NIDDM subjects had larger IMT, higher levels of triglycerides, and lower concentrations of high-density lipoprotein (HDL) cholesterol compared with control subjects. IMT was positively correlated to age and systolic blood pressure and inversely to HDL cholesterol in both groups. The prevalence of CA was 46% in NIDDM subjects and 18% in control subjects. In multiple regression analysis, IMT was the only variable significantly associated to CA. CONCLUSIONS: IMT of CCA is enlarged in NIDDM subjects compared with control subjects. Its association with carotid plaques and/or stenosis might be of importance to detect early atherosclerotic lesions in the carotid arteries.

Early extracoronary atherosclerosis and coronary heart disease risk factors in a sample of civil servants in southern Italy.

One hundred and thirty-eight male subjects working as civil servants in the Catanzaro city hall, aged over 45, underwent Echo-Doppler examination of carotid and femoral arteries. Forty-one subjects (30%) presented evidence of early atherosclerotic lesions in at least 1 of the 10 examined arteries. Age, systolic blood pressure, serum triglycerides and serum glucose were higher in this group when compared with subjects without evidence of extracoronary atherosclerosis (EA), while HDL cholesterol and apolipoprotein A-I were lower. After adjustment for age, only serum triglycerides and apolipoprotein A-I levels remained significantly different. Only 21 subjects had no major coronary heart disease (CHD) risk factors, 46 had one, 47 two and 24 more than two risk factors. The prevalence of lesions was significantly higher in individuals with total cholesterol/HDL cholesterol ratio greater than 5. The presence of smoking and hypertension was almost equally represented in individuals with or without lesions. Serum triglycerides, total cholesterol/HDL cholesterol > 5 and apolipoprotein A-I seem to play a fundamental role in the development of EA, as detected by Duplex examination of carotid and femoral arteries. Age is also closely related to the presence of lesions, probably reflecting the exposure duration to CHD risk factors.

Increase in the size of the amino acid pool is sufficient to activate translation of early trypsin mRNA in Aedes aegypti midgut.

Early trypsin is a female-specific protease present in the midgut of the yellow fever mosquito Aedes aegypti during the first 4-6 h after ingestion of a blood meal. Transcription of the early trypsin gene occurs after adult emergence under control of juvenile hormone, but the transcript remains untranslated before feeding. Early trypsin was in vitro translated using mRNA extracted from midguts of unfed and fed females, indicating that there are not structural features in the early trypsin mRNA that impede translation in vitro. Eight single protein meals exhibiting different molecular weights and amino acid composition, as well as ingestion of several amino acid mixtures of different complexity, had the ability to prompt early trypsin translation. In contrast, ingestion of saline, latex or midgut-filling sugars were unable to induce early trypsin mRNA translation. In addition intra-thoracic injection of an amino acid solution induced early trypsin translation, while injection of saline or albumin failed. In summary an increase in the size of the midgut amino acid pool by feeding or injection of an amino acid solution was sufficient to induce translation of early trypsin mRNA; 35S-labeled amino acids, fed with a protein meal, were incorporated into newly synthesized early trypsin; the first phase of trypsin synthesis is likely induced by an initial rapid increase in the concentration of amino acids in the midgut cells after ingestion of a blood meal.

Modified nucleosides in body fluids of tumor-bearing patients.

The catabolism of nucleic acids, particularly tRNA, produces a variety of modified nucleosides which are not reutilized by mammalian cells. Investigation of these compounds in body fluids, mainly urine, has recently provided evidence of altered metabolic situations in tumor-bearing patients. The factors involved in the alterations of modified nucleosides formation are connected with altered tRNA-modifying enzymes and/or altered turnover of subpopulations of tRNA. A common pattern in tumor cells or tissues is the presence of isoaccepting tRNA species containing aberrant nucleoside modifications. Several modified nucleosides have been detected and quantitated by HPLC analysis of the urine of normal subjects and cancer patients. Results obtained, in the authors' laboratory, among others, indicate a possible correlation between urinary excretion of these compounds and the course of the disease, with implications for the follow-up of therapeutic treatment. Particular reference should be made to psi, which appears to be a suitable marker for monitoring these subjects. The data from the authors' laboratory also show that the analysis of modified nucleosides in blood may be considered a useful tool in the search for proper markers associated with the cancer status. In this respect psi is suggested as a biochemical indicator for cancer patients.

Association between ACE-D/D polymorphism and hypertension in type II diabetic subjects.

The ACE gene has recently been shown to be associated with myocardial infarction, especially in subjects considered at low risk for coronary heart disease (CHD) according to common classification criteria. The possible relationship between deletion polymorphism in this gene and CHD risk factors, as well as asymptomatic extracoronary atherosclerosis, has been investigated in the present study. One hundred and seventy-four subjects, enrolled in a cardiovascular disease prevention study, underwent clinical and biochemical examination and ACE-I/D polymorphism determination. Subjects > 45 years of age (n = 107) also received echo-Doppler examination of the carotid arteries. Based on the results of ACE-I/D polymorphism, subjects were divided into three groups: homozygous for deletion (D/D), homozygous for insertion (I/I) and heterozygous (I/D). The prevalence of CHD risk factors as well as of extracoronary atherosclerosis was similar in the three genotype groups. Similarly, there was no association between the presence of atherosclerotic lesions and genotype in subjects at low and high CHD risk. Ten subjects with diabetes mellitus had ACE-D/D genotype. Among these subjects seven had hypertension. Eight subjects with diabetes mellitus had ACE-I/D genotype and only one of these was hypertensive. None of the ACE-I/I subjects was diabetic. ACE-I/D polymorphism seems to play a role in the development of hypertension, at least in diabetic subjects. Its determination may help to identify and monitor diabetic subjects prone to hypertension.

Prevalence of intestinal metaplasia in the distal oesophagus, oesophagogastric junction and gastric cardia in symptomatic patients in north-east Italy: a prospective, descriptive survey. The Italian Ulcer Study Group "GISU".

BACKGROUND: Incidence of adenocarcinoma of distal oesophagus and gastric cardia, probably arising from areas of intestinal metaplasia, has been increasing rapidly. AIMS: To define prevalence of intestinal metaplasia of distal oesophagus, oesophagogastric junction and gastric cardia and to evaluate potential associated factors, by means of a prospective multicentre study including University and teaching hospitals, and primary and tertiary care centres. PATIENTS: Each of 24 institutions involved in study enrolled 10 consecutive patients undergoing first-time routine endoscopy for dyspeptic symptoms. METHODS: Patients answered symptom questionnaires and underwent gastroscopy Three biopsies were taken from distal oesophagus, oesophago-gastric junction and gastric cardia, and were stained with haematoxylin and eosin. Specimens were also evaluated for Helicobacter pylori infection. RESULTS: A total of 240 patients (124 male, 116 female; median age 56 years, range 20-90) were enrolled in study. Intestinal metaplasia affected distal oesophagus in 5, oesophago-gastric junction in 19 and gastric cardia in 10 patients. Low-grade dysplasia was found at distal oesophagus and/or oesophago-gastric junction of 3/24 patients with intestinal metaplasia vs 2/216 without intestinal metaplasia (p<0.05). A significant association was found between symptoms and presence of intestinal metaplasia, regardless of location, and between Helicobacter pylori infection and intestinal metaplasia at oesophago-gastric junction. CONCLUSIONS: Intestinal metaplasia of distal oesophagus, oesophagogastric-junction and gastric cardia is found in a significant proportion of symptomatic patients undergoing gastroscopy and is associated with dysplasia in many cases. Although prevalence of dysplasia seems to decrease when specialized columnar epithelium is found in short segment, or even focally in oesophago-gastric junction, these small foci of intestinal metaplastic cells may represent source of most adenocarcinomas of cardia.

Bacterial load and protein deposits on 15-day versus 1-day disposable hydrophilic contact lenses.

PURPOSE: This study quantified the bacterial load and protein deposits on 1- and 15-day disposable contact lenses after use in normal wearers. METHODS: Sixteen patients were randomly assigned to a 1-day contact lens (1-Day Acuvue) in one eye and to a 15-day contact lens (Acuvue) in the contralateral eye. Only one specified solution was allowed for the care of 15-day lenses. All patients were evaluated every month for 6 months (at times T1, T2, T3, T4, T5, T6). At times T1, T3, and T5, the lenses were removed in a sterile fashion and sent for laboratory quantification of Staphylococcus aureus and Pseudomonas aeruginosa. At T2, T4, and T6, quantification of protein deposits was determined, and at T0 and T6, impression cytology of the conjunctiva was performed. RESULTS: P. aeruginosa was not identified on any lens. At T1, T3, and T5, S. aureus was significantly greater on the 1-day versus 15-day lenses (p < 0.001). In contrast, protein deposits were significantly greater on the 15-day lenses at all time points (T2, T6: p < 0.01; T4: p < 0.05). Impression cytology of the 15-day lens eyes revealed a worsening trend compared to the 1-day lens; however, no statistically significant differences were found between the two groups (p = 0.29). CONCLUSION: Results of this study suggest that the use of cleaning and preservative solutions can alter the ocular surface bacterial environment of the contact lens wearer and that these changes are not a direct consequence of contact lens wear. The bactericidal activity of these solutions could, with time, also affect ocular surface cells, leading to contact lens intolerance and ocular surface disease.

[Asymptomatic arteriopathy of the lower limbs. Prevalence and risk factors in a population of southern Italy]. / Arteriopatia asintomatica degli arti inferiori. Prevalenza e fattori di rischio in una popolazione del sud Italia.

Peripheral vascular diseases, both symptomatic and asymptomatic, are strong predictors of total and cardiovascular mortality. The commonly used Rose questionnaire, although highly specific, has a low sensitivity to detecting peripheral vascular disease and is not adequate for asymptomatic subjects. Doppler ultrasound measurement of the ankle/brachial systolic blood pressure ratio is a non-invasive, reproducible and accurate method of assessment of peripheral vascular disease and has been validated by angiography. METHODS. Five hundred and ten subjects, corresponding to fifty percent of the people working as civil servants in the Catanzaro city hall, were invited to join the study by a letter. Three hundred and eighty four participated. Exclusion criterion was claudicatio intermittens as detected by Rose questionnaire. All the subjects filled a questionnaire to assess coronary heart disease risk factors and underwent a full clinical examination. Brachial blood pressure was measured on both arms with participants in supine position, just before ECG. The systolic ankle blood pressure was measured with ultrasonic technique. The blood pressure cuff was placed just proximal to the medial malleolus. The ankle-brachial systolic pressure index (Winsor Index) was determined by dividing the highest of the posterior tibial or dorsalis pedis pressures by the highest brachial pressure. A limit of 0.95 was chosen to identify subjects with peripheral arterial disease. Venous blood for serum cholesterol and triglycerides, apolipoprotein AI and B and blood glucose, was collected after an overnight fasting, into Vacutainer Tubes (Becton & Dickinson). RESULTS. No subject had claudicatio intermittens. Sixteen subjects were excluded from the statistical analysis because of missing data. Two hundred and sixty-three were males and 105 females. Twenty-one (5.7%) out of 368 participants had a Winsor Index < 0.95 in at least one leg. These subjects had higher values of systolic and diastolic blood pressure compared to normal subjects whereas no differences were observed with regard to age, BMI, lipid profile and blood glucose. Furthermore the prevalence of hypertension was higher in the group of subjects with asymptomatic peripheral arterial disease. The prevalence of other risk factors for atherosclerosis (cigarette smoking, hyperlipidemia, diabetes mellitus, obesity) was similar in subjects with or without peripheral arterial disease. DISCUSSION. In the present study the prevalence of Winsor Index < 0.95 was 5.7%, similar to that reported by other authors. Hypertension was the only risk factor for atherosclerosis associated with peripheral arterial disease. Other authors also reported a higher prevalence of cigarette smoking among subjects with peripheral disease. In our population this association was not found but the participants were younger and consequently the exposure to this risk factor was shorter. CONCLUSION. The measurement of systolic ankle blood pressure by Doppler ultrasounds is a non-invasive, well accepted, highly specific and sensitive method to detect asymptomatic peripheral arterial disease. It might be of value in better defining the cardiovascular risk profile both in epidemiologic studies and clinical practice, especially in subjects with hypertension.

[Clinical and therapeutic studies of pancreatitis]. / Contributo casistico, clinico e terapeutico in tema di pancreatite.

The literature on the medical management of pancreatitis is reviewed. Reference is made to successful results obtained in 30 personal cases with a semimedicamentous protocol, in which an antipancreatitic activity in the true sense was obtained by administering aprotinine and glucagon. Eight subjects presented acute or recrudescent chronic forms, 12 pancreatitis combined with cholelithiasis, 5 secondary forms following penetrating duodenal ulcers, and 5 forms arising after stomach, duodenal or bile duct surgery. The evaluation of each case is described and the conclusion is drawn that intensive, timely medical therapy will secure resolution in the majority of cases.

Reality approximated, external and internal.

Some of Heinz Hartmann's theoretical formulations concerning the adaptive functions of the ego are described as they apply to the case of a patient analyzed between the ages of five and eight. This boy, vulnerable because of prematurity, was born at twenty-six weeks weighing 2.7 pounds and remained in the hospital newborn unit for sixty-six days. Difficulties and vulnerabilities resulting from this experience are discussed as they appeared in the analysis.

Anna Freud: observation and development.

Anna Freud taught the importance of observation, suggesting that students jot down their observations in a systematic manner. She urged observers to amplify their notes, which were later discussed in meetings. Observations made in the nursery school, for example, were discussed afterwards and classified in a file under appropriate headings somewhat similar to the technique used at the Anna Freud Centre. In this paper I describe my observations of a subject as an infant and a toddler with special reference to the way she looked intensely at the world around her. To some degree, the way she herself looked-i.e., her appearance-was also interesting. The relationship between the child's looking in infancy and the oedipal child's sexual curiosity, exhibitionism, and scoptophilia is suggested by these observations.
