RESUMO
BACKGROUND: Limited information exists about epidemiology and management of mushroom poisoning. We analyzed and described epidemiology, clinical presentation, and clinical course of mushroom-poisoned patients admitted to emergency departments (EDs) of the Province of Parma, Italy. METHODS: Data from the database of mycological service were matched with clinical information retrieved from hospitals' database, from January 1, 1996 to December 31, 2016. RESULTS: Mycologist consultation was obtained in 379/443 identified mushroom poisonings. A remarkable seasonality was found, with significant peak in autumn. Thanks to the collaboration, the implicated species could be identified in 397 cases (89.6%); 108 cases (24.4%) were due to edible mushrooms, Boletus edulis being the most represented (63 cases). Overall, 408 (92%) cases presented with gastrointestinal toxicity. Twenty cases of amatoxin poisoning were recorded (11 Amanita phalloides and 9 Lepiota brunneoincarnata). One liver transplantation was needed. We observed 13 cases of cholinergic toxicity and 2 cases of hallucinogenic toxicity. Finally, 46 cases were due to "mixed" toxicities, and a total of 69 needed hospitalization. CONCLUSIONS: Early identification and management of potentially life-threatening cases is challenging in the ED, so that a mycologist service on call is highly advisable, especially during periods characterized by the highest incidence of poisoning.

BACKGROUND: Clinical trials have so far shown controversial results as regards the standard of care for treating uncomplicated acute appendicitis (uC-AA). High operational risk adult patients (HORAP) could represent selected patients where primary antibiotic conservative therapy (pACT or A) could be indicated. METHODS: We carried a comprehensive search of the PubMed searching engine in the English language scientific literature from 1995 to 2015, using medical subject headings "antibiotics", "uncomplicated appendicitis", "appendicectomy", "conservative treatment", "surgery" and "randomized clinical trial". All RCTs comparing the outcomes of pACT versus primary surgical open or laparoscopic appendectomy (pSOLA or S) as primary treatment options for uC-AA were identified. Inclusion criteria for our analytical review were RCTs evaluating outcomes in terms of or related to all of the following four parameters: treatment efficacy, post therapeutic/operative complications, in hospital length of stay (LOS) and recurrence. RESULTS: The conclusion of all five RCTs considered antibiotics alone in the treatment of AA as an efficient and non inferior therapeutic option respect to surgery. Primary ACT was characterised by a higher LOS, a higher rate of recurrence and a lower rate of postoperative complication than pSOLA. CONCLUSIONS: Based on the current body of evidence, an appropriate pACT could be a rational tailored primary treatment option for CT proven uC-AA in HORAP. Accurate diagnoses and surgical risk stratification in patients with uC-AA could aid decision making for target therapy. However, results of large sample prospective multicenter RCTs are required to routinely recommend pACT for uC-AA in the clinical practice.

UNLABELLED: This survey describes the epidemiology of approximately 1800 low-energy humeral fractures seen in a large emergency department in Northern Italy over 7 years (2007-2013), highlighting the differences from previous Italian studies. PURPOSE: The purpose of this study was to determine the incidence of humeral fractures due to low-energy trauma in patients 40 years of age or older referred to a large Emergency Department (Parma, Northern Italy) in a 7-year period (2007-2013). METHODS: All humeral fractures referred to the emergency department of the Academic Hospital of Parma (the main hospital in the province with a catchment area of approximately 345,000) were retrieved from the hospital database using both ICD-9CM codes and text strings. The diagnosis of humeral fracture due to low-energy trauma was confirmed by medical records and X-ray reports, after exclusion of injuries due to a clear-cut high-energy trauma or cancer. RESULTS: The query identified 1843 humeral fractures (1809 first fractures), with a clear predominance in women (78 %). Fractures of the proximal humerus represented the large majority of humeral fractures (more than 85 %), with an incidence progressively increasing with age (more than 60-fold in women and 20-fold in men). Simultaneous fractures (hip in particular) were frequent especially after 85 years of age (1 out of 8 cases). When compared to other Italian studies, the incidence of humeral fractures was significantly lower than that derived from discharge data corrected for hospitalization rate (standardized rate ratio 0.74; p < 0.001), while the pattern of age-related changes was significantly different from that computed by applying the ratio between hip and humeral fractures observed in Malmö, Sweden, to the Italian hip fracture rates. CONCLUSIONS: This study gives an up-to-date description of the epidemiology of low-energy humeral fractures in Italy. Our results partly differ from previous Italian studies based on indirect estimations.

UNLABELLED: In this survey, the proportion of patients with distal forearm fractures admitted to the Parma University Hospital during 2012 (13 %) was relatively low and generally lower than that reported in other studies. In our region, the main orthopedic approach remains conservative. PURPOSE: The purpose of this study was to define the ratio between hospitalized and non-hospitalized fragility fractures of the distal forearm in our province (Parma, Northern Italy). METHODS: All forearm fractures referred during 2012 to the emergency department of the Parma University Hospital (the main hospital in the province with a catchment area of approximately 345,000) were retrieved from the hospital database using both ICD-9-CM codes and text strings. The diagnosis of distal forearm fracture due to low-energy trauma and the need for hospitalization were individually confirmed by medical records and X-ray reports. The analysis was limited to subjects aged 40 years and over. RESULTS: In both sexes combined, 66 subjects out of 505 were hospitalized (13.1 %; confidence interval (CI) 95 % 10.4-16.3 %), 47 immediately (8.1 %) and 25 (5 %) after a few days. The percentage of cases hospitalized was 12 % in women (CI 95 % 9.2-15.6 %) and 17 % in men (CI 95 % 11.1-25 %; p = 0.16). CONCLUSIONS: The percentage of fragility distal forearm fractures hospitalized in our area is relatively low and generally lower than that reported in other studies.

Migraine is a common disabling headache disorder that is conventionally classified according to the presence or absence of aura. The pathogenesis of this disorder entails a complex interplay of neurovascular factors, that trigger reduction of cerebral blood flow followed by reactive vasodilatation. Despite major emphasis has been placed on the investigation of putative biomarkers that could predict response to specific treatments and prophylaxis, less focus has been directed at the association between migraine and erythrocytosis. Erythrocytosis is typically accompanied by hyperviscosity, that is now considered a crucial determinant in the pathogenesis of migraine. The results of some epidemiological investigations are in substantial agreement to confirm the existence of a significant relationship between increased haemoglobin levels and migraine, whereas some case reports have also reported an effective improvement of symptoms after reduction of erythrocyte count by therapeutic venesection. Interesting evidence has recently emerged from the assessment of red blood cell distribution width (RDW), a simple and inexpensive measure of anysocytosis that has been also associated with a variety of ischaemic and thrombotic disorders other than migraine. The aim of this review was to provide an overview of the current clinical and epidemiological evidence linking migraine and erythrocyte biology.

AIM: The aim of this paper was to assess short and long term prognostic value of the OESIL risk score (ORS), a risk stratification rule for syncope which consider abnormal ECG, age > 65, history of cardiovascular diseases, lack of prodromal symptoms to identify patients at higher risk of mortality (ORS≥2) to be admitted. METHODS: This is a prospective cohort study in which syncopal recurrences, readmission for other reasons, major therapeutic procedures, cardiovascular events, death for any reason, were assessed in a group of 200 syncopal patients at both 1 month and 1 year after discharge from an Emergency Department Observation Unit. RESULTS: Multinomial logistic regression analysis showed that ORS ≥2 is not associated with any endpoint, except major procedures. Conversely, ORS≥3 was a strong predictor of at least 1 adverse event within 1 month and severe outcomes within 1 year, particularly for non-syncopal readmission (P<0.005), major procedures (P<0.002), cardiovascular events (P<0.023), and death for any cause (P<0.022). CONCLUSION: Our patient group was significantly older than the ORS derivation cohort (72.4±15.1 vs. 59.5±24.3 yrs) and mostly above the age considered as 1 point in the ORS, so it is rather understandable that only a more restrictive cut-off might be advantageous for identifying high risk patients. On the evidence of a progressive ageing of patients presenting at the EDs, we suggest to use a ³3 ORS threshold when deciding for admission.

BACKGROUND: A marked geographic variability has been reported in stone disease, partially attributed to the Mean Annual Temperature (MAT), as well as to the seasonal fluctuations of climatic conditions. Accordingly, peaks in Emergency Department (ED) visits for renal colic are commonplace during the summer. MATERIALS AND METHODS: The aim of this study was to assess the influence of day-by-day climate changes on the number of visits as a result of renal colic in the ED (City of Parma, northern Italy, temperate continental climate). A total of 10,802 colic episodes were retrieved from the database during a period of 3286days (January 2002 to December 2010). RESULTS: The analysis of the data confirms a peak of renal colic cases during the summer, especially in July (maximum number of 4.1 cases of renal colic per day), and a winter nadir (minimum number of 2.7 cases of renal colic per day, in February). The linear regression analysis shows a high and significant correlation between the mean number of cases of renal colic per day and both the mean daily temperature (positive association, R=0.93; p<0.0001) and the mean daily humidity (negative association, R=-0.82; p<0.0001). The influence of temperature and humidity on the incidence of renal colic cases varied widely among age groups, the highest incidence seen in patients aged between 30 and 40years, and the lowest seen for those aged <20 and >70years of age. CONCLUSION: The combined data suggest that the hot and dry climate would favor an acceleration of the process of stone formation, which seems more pronounced in the older population.

PURPOSE: The authors sought to determine the prognostic value of computed tomography coronary angiography (CTCA) in patients with acute chest pain (ACP). MATERIALS AND METHODS: A total of 145 consecutive patients (75 men; 64±12 years) with ACP were referred from the Emergency Department for CTCA, which was performed with a standard protocol using a 64-slice scanner. Patients were stratified according to the Morise clinical score (low, intermediate, high) and to the CTCA findings [absence of coronary artery disease (CAD), nonobstructive CAD, obstructive CAD]. Patients were followed up for the occurrence of major events: cardiac death, nonfatal myocardial infarction, unstable angina and revascularisation. RESULTS: One hundred and twenty-seven (87.6%) patients were without a history of CAD, and 18 (12.4%) patients had a history of CAD. Obstructive CAD (>50% luminal narrowing) was detected in 35 (24%) patients; nonobstructive CAD (≤ 50% luminal narrowing) in 62 (43%) and absence of CAD in 48 (33%) patients. During a mean follow-up of 20 ± 3 months, 20 events occurred (four hard events). Sixteen events (three hard events) occurred in patients without a history of CAD, and four events (one hard event) occurred in patients with a history of CAD. In patients with absence of CAD as detected by CTCA, the rate of events was 0%. At multivariate analysis, hypercholesterolaemia and obstructive CAD were significant predictors of events (p<0.05). CONCLUSIONS: An excellent prognosis was observed in patients with ACP and normal CTCA. CTCA shows the potential for optimal stratification of patients with ACP.

PURPOSE: This study was done to evaluate the diagnostic accuracy of 64-slice computed tomography coronary angiography (CTCA) for the detection of significant coronary artery stenosis in the real clinical world. MATERIALS AND METHOD: From the CTCA database of our institution, we enrolled 145 patients (92 men, 52 women, mean age 63.4 +/- 10.2 years) with suspected coronary artery disease. All patients presented with atypical or typical chest pain and underwent CTCA and conventional coronary angiography (CA). For the CTCA scan (Sensation 64, Siemens, Germany), we administered an IV bolus of 100 ml of iodinated contrast material (Iomeprol 400 mgI/ml, Bracco, Italy). The CTCA and CA reports used to evaluate diagnostic accuracy adopted > or =50% and > or =70%, respectively, as thresholds for significant stenosis. RESULT: Eleven patients were excluded from the analysis because of the nondiagnostic quality of CTCA. The prevalence of disease demonstrated at CA was 63% (84/134). Sensitivity, specificity and positive and negative predictive values for CTCA on a per-segment, per-vessel, and per-patient basis were 75.6%, 85.1%, 97.6%; 86.9%, 81.8%, 58.0%; 48.2%, 68.1%, 79.6%; and 95.7%, 92.3%, 93.5%, respectively. Only two out of 134 eligible patients were false negative. Heart rate did not significantly influence diagnostic accuracy, whereas the absence or minimal presence of coronary calcification improved diagnostic accuracy. The positive and negative likelihood ratios at the per-patient level were 2.32 and 0.041, respectively. CONCLUSION: CTCA in the real clinical world shows a diagnostic performance lower than reported in previous validation studies. The excellent negative predictive value and negative likelihood ratio make CTCA a noninvasive gold standard for exclusion of significant coronary artery disease.

BACKGROUND: Intracranial haemorrhage (ICH) is the type of stroke associated with the highest death rate, and about 30% of ICH occurs in patients on antithrombotic treatment. This study relates clinical presentations and outcome of ICH patients on oral anticoagulant (OA) or antiplatelet (AP) therapy admitted to 33 Italian emergency departments (ED). METHODS: Consecutive patients were enrolled after cranial computed tomography (CT). Primary outcome was the Modified Rankin Scale (MRS) score at 3 months of follow-up. Common descriptive statistics were computed after stratification for traumatic or spontaneous ICH and identification of the anatomical location of bleeding. Multivariate logistic regression was used to assess predictors of death. RESULTS: We recruited 434 patients on AP therapy and 232 on OA. There were 432 spontaneous and 234 traumatic ICH patients. The proportions of AP and OA patients undergoing neurosurgery were 21.8 and 19.4%, respectively, while < 30% underwent procoagulant medical treatment. At the 3-month follow-up, the case fatality rate was 42.0%, while disability or death (MRS 3-6) was 68.1%. The odds ratio for death in OA versus AP patients was 2.63 (95% CI 1.73-4.00) in the whole population and 2.80 (95% CI 1.77-4.41) in intraparenchymal event patients. Glasgow Coma Scale, age, spontaneous event and anticoagulant use were found to be predictors of death both in traumatic and spontaneous events. CONCLUSION: This study confirms the high prevalence of death or disability in OA and AP patients with ICH. As far as the determinants of mortality and disability are concerned, the results of this study might be useful in the clinical management and allocation of resources in the ED setting. The observed low use of procoagulant therapy highlights the need for ED educational programmes to heighten the awareness of available and effective haemostatic treatments.

Biochemical and anthropometric data were collected in 9 subjects with anorexia nervosa before and after enteral nutrition by the nasogastric route. All subjects but one accepted the treatment which was stopped as soon as an adequate spontaneous food intake was resumed. Enteral nutrition caused a significant increase of mid-arm muscle circumference and of tricipital skinfold. Body weight gain was remarkable, averaging a rate of 8.22 kg/month. This value was not different from the levels attained by anorectic subjects put on total parenteral nutrition. Furthermore, a significant rise of some biochemical indexes, namely prealbumin and total iron binding capacity, was achieved. The most impressive drawbacks of enteral nutrition were occasional hypophosphatemia and moderate rise of serum aspartate and alanine aminotransferases. Both of these abnormalities were transient and apparently not associated with clinical disturbances.

In this paper we present the results of a 12-month double-blind clinical multicenter study assessing the effects of synthetic salmon calcitonin (CT) administration in a group of white postmenopausal osteoporotic women. Treated patients were given 100 MRC units of synthetic salmon CT injected i.m. in the morning every other day. Control patients received a placebo injection. All patients received 500 mg of elementary calcium p.o., b.i.d. Bone mineral content (BMC) was measured at the extreme distal radius of the nondominant arm by a dual photon bone densitometer which utilizes two radionuclides, 241Am and 125I, with energies of about 60 keV and 30 keV respectively. Biochemical parameters of calcium-phosphorus metabolism were also measured. After 12 months of treatment a significant mean increment of BMC and nondialyzable OHPr/creatinine values and a significant decrease of total OHPr/creatinine values were observed in the treated group, while controls showed a significant decrease in BMC values. These results, together with the observation that in some patients the decrease in total OHPr/creatinine values was not accompanied by an increment of BMC, show that long-term salmon CT treatment may be of benefit in postmenopausal osteoporosis and that the effects of CT on bone mass may be due not only to the inhibition of bone resorption but also to the stimulation of bone formation.

It is generally accepted that calcitonin (CT) induces a decrement in cytosolic Ca++, and an increase of cAMP in target cells of several organs and tissues. This happens particularly in bone, where osteoclast activity and size decreases, along with the widely-known hypocalcaemic and hypophosphoraemic effect of the hormone. The physiological role of CT appears to be of importance in pregnancy and perhaps in infancy, when it antagonizes possible excessive bone loss. Some experimental evidence shows that CT may be involved in the maintenance of post-meal calcaemia. It is not yet established whether paucity of CT plays any important role in the pathogenesis of pathological conditions such as post-menopausal and senile osteoporosis.

The assessment of bone status is so far usually performed by means of the relatively simple methods of radiographs and radiogrammetry, which are not always able to give a correct information about bone mineral content (B.M.C.) especially in cases of cortical osteoporosis. Among the other non-invasive methods, single- and dual-photon absorptiometry are of particular interest for their relatively low cost, precision, accuracy and repetitibility, giving the patient a very slight dose of radioactivity. Dual-photon device, in particular, offers the possibility to investigate B.M.C. in the bones surrounded with large amount of tissue, even in obese people. To assess bone status of feminine population, we have analyzed 238 patients, divided into 3 groups (normal pre- and post-menopausal women, and osteoporotic) measuring their radius and lumbar spine B.M.C. with single- and dual-photon absorptiometry. As a result, B.M.C. of both measuring sites appears closely correlated with age, and with the duration of menopause. In our group, cortical bone density showed a postmenopausal rate of loss higher than the trabecular. Vertebral measurements, too, were more closely correlated with age when corrected for body surface area. Osteoporotic group showed a B.M.C. significantly lower than the age-matched group of normal women both in spine and in radius: in conclusion, all these findings stress the importance of a widespread population surveillance in order to individuate and treat the patients at risk of spontaneous fractures.
