Abstract Background In order to identify relevant targets for change, it is essential to know the reliability of incident staff reporting. The aim of this study is to compare the incidence and type of unintended events (UE) reported by facilitated Intensive Care Unit (ICU) staff with those recorded concurrently by an observer. Methods The study is a prospective data collection performed in two 4-bed multidisciplinary ICUs of a teaching hospital. The format of the UE reporting system was voluntary, facilitated and not necessarily anonymous, and used a structured form with a predetermined list of items. UEs were reported by ICU staff over a period of 4 weeks. The reporting incidence during the first fourteen days was compared with that during the second fourteen. During morning shifts in the second fourteen days, one observer in each ICU recorded any UE seen. The staff was not aware of the observers' study. The incidence of UEs reported by staff was compared with that recorded by the observers. Results The staff reported 36 UEs in the first fourteen days and 31 in the second.. The incidence of UE detection during morning shifts was significantly higher than during afternoon or night shifts (p < 0.001). Considering only working day morning shifts, the rate of UE reporting by the staff per 100 patient days was 26.9 (CI 95% 16.9–37.0) in the first fourteen day period and 20.3 (CI 95% 10.3–30.4) in the second. The rate of UE detection by the observers was 53.1 per 100 patient days (CI 95% 40.6–65.6), significantly higher (p < 0.001) than that reported concurrently by the staff. There was excellent agreement between staff and observers about the severity of the UEs recorded (Intraclass Correlation Coefficient 0.869). The observers recorded mainly UEs involving Airway/mechanical ventilation and Patient management, and the staff Catheter/Drain/Probe and Medication errors (p = 0.025). Conclusion UE incidence is strongly underreported by staff in comparison with observers. Also the types of UEs reported are different. Invaluable information about incidents in ICU can be obtained in a few days by observer monitoring.

Aim: To determine the incidence of Post Traumatic Stress Disorder (PTSD) related symptoms in a population of intensive care unit (ICU) admitted patients and the relationship between PTSD-related symptoms and memories of ICU., Methods: Adults consecutively admitted to an ICU of a University hospital during 1 year, who stayed in the ICU at least 3 days, were prospectively studied. A questionnaire (ICU memory tool) was administered to 84 patients 1 week after ICU discharge and to 63 of them after 3 months. Past medical history and clinical variables present during ICU stay were collected., Results: At the 1st interview, 5 patients (5.9%) did not remember to have been in ICU. Of the remaining 79 patients (males 59.5%, median age 69 years, SAPS II 34, APACHE II 14 and ICU stay 5 days), 4 reported intrusive memories and none panic attacks. The Impact of Events Scale (IES), available in 3 of them, scored in medium/high levels. Only the median number of factual memories reported by the patients with and without intrusive memories was significantly different (4 interquartile range 2-5 vs 8 interquartile range 6-10; p=0.002). The patients with intrusive memories at the 1st interview did not report them at the 2nd interview. Two patients not having panic or intrusive memories at the 1st interview reported PTSD-related symptoms after 3 months., Conclusions: In a general ICU population, few patients (5%) have PTSD-related symptoms and those who present those symptoms report less factual memories of ICU stay.

Introduction: The aims of the present study were to assess patients' memories of their stay in the intensive care unit (ICU) over time, using the Italian version of the ICU Memory (ICUM) tool, and to examine the relationship between memory and duration of ICU stay and infection., Patients and Method: Adult patients consecutively admitted to a four-bed ICU of a university hospital, whose stay in the ICU was at least 3 days, were prospectively studied. The ICUM tool was administered twice: face to face 1 week after ICU discharge to 93 patients (successfully in 87); and by phone after 3 months to 67 patients. Stability of memories over time was analyzed using Kappa statistics., Results: Delusional memories appeared to be the most persistent recollections over time (minimum kappa value = 0.68), followed by feelings (kappa value > 0.7 in three out of six memories) and factual memories (kappa value > 0.7 in three out of 11 memories). The patients without a clear memory of their stay in the ICU reported a greater number of delusional memories than did those with a clear memory. Of patients without infection 35% had one or two delusional memories, and 60% of patients with infection had one to four delusional memories (P = 0.029)., Conclusion: The ICUM tool is of value in a setting and language different from those in which it was created and used. Delusional memories are the most stable recollections, and are frequently associated both with lack of clear memory of ICU experience and with presence of infection during ICU stay.

In order to evaluate the possible relationships among hormonal status, physical activity and bone density, we carried out a study on two groups of female athletes engaged in different levels of physical activity. We measured the following hormones: luteinizing hormone (LH), folliculo-stimulating hormone (FSH), 17-beta-oestradiol (E2), progesterone (PRG), prolactin (HPRL), estrone (E1), thyreo-stimulating hormone (TSH), free thyroxine (FT4), and the markers of phosphate-calcium metabolism: calcitonine (CT), parathormone (PTH), and osteocalcine (BGP). We also measured bone mineral density (BMD). All of these variables were related to the amount of work performed during training. The groups were defined as follows: medium workload (group M, n = 10) and heavy workload (group H, n = 20), engaged in 10 and 18 hours of weekly training at 35 and 60 average percent of VO2max, respectively. All of the hormones and the markers of calcium-phosphate metabolism studied were normal; BMD was also normal for all subjects except for two sisters in group M with reduced BMD. The group H athletes with regular menstrual cycles were found to have an upper limit normal BMD. From these data we conclude that in regularly menstruating athletes an increase in BMD induced by heavy physical activity is evident, while in dysmenorrhoeic athletes the effect of physical activity compensates, to some extent, for the hypothetical bone mineral reduction possibly caused by the hormonal imbalance.

The normal ranges and mathematical equations of bone mineral content (BMC), normalized to radial width (BMC/W) vs. age at the distal radius, were obtained by single photon absorptiometry (SPA), and compared in two different normal populations, one of postmenopausal females and the other of control males. The female population included 1359 postmenopausal women, aged 35 to 75 years; normal control males were 162, of the same age. The results obtained in the two groups of patients show a statistically significant (p less than 0.001) correlation between age and BMC/W, expressed in a polinomial third-degree regression. The slope of the regression curves is quite different between males and females: the mean decrement, evaluated from regression polinomial fits, results 0.5% per year for normal females, and 0.3% per year for normal males. The maximum decrement (1% per year) is observed at the mean age of 51 years, which is the average age of peri-menopausal women in our province (Ferrara). The authors believe SPA to be a simple and reliable technique in measuring peripheral bone loss rate. SPA may be useful in the diagnosis and treatment of postmenopausal women, but is not recommended in the short-term follow-up of osteoporosis.

Bone lesions are the main sign of neoplastic proliferation of multiple myeloma (MM), a disseminated malignant disease which originates in, invades and replaces normal bone marrow. The most characteristic radiographic pattern is a focal lytic lesion, well-defined or "punched-out", generally with no surrounding bone reaction. The association is confirmed between MM and osteoporosis, as reduced bone density (osteopenia) and pathologic fractures (ribs, spine). This paper is aimed at evaluating the importance of osteopenia in both diagnosis and prognosis of MM. Eighteen patients affected with MM were examined with quantitative computed tomography (QCT) and dual-energy X-ray absorptiometry (DEXA) for bone densitometry in lumbar spine and proximal femur. The patients (12 males and 6 females) were classified according to Durie's clinical criteria and to the radiographic patterns suggested by Merlini. The results indicate the patients with an advanced clinical stage (III) and scintigraphic expansion of bone marrow to have low densitometric values on both QCT and DEXA. There was substantial agreement between the 2 methods, but DEXA had a higher number of false positives. Instrumental diagnostic protocol may be thus planned as follows: 1) conventional radiography; 2) bone marrow scintigraphy; 3) bone densitometry of lumbar spine, with QCT. The patient is then to be followed with conventional and/or digital radiography in symptomatic locations, and with bone scintigraphy.
