Comparison between azacitidine and decitabine as front-line therapy in elderly acute myeloid leukemia patients not eligible for intensive chemotherapy.

We compared the efficacy of azacitidine (AZA) and decitabine (DEC) in elderly patients with untreated AML, diagnosed according to WHO criteria. In the two groups, we evaluated complete remission (CR), overall survival (OS) and disease free survival (DFS). The AZA and DEC groups included 139 and 186 patients, respectively. To minimize the effects of treatment selection bias, adjustments were made using the propensity-score matching method, which yielded 136 patient pairs. In the AZA and DEC cohort, median age was 75 years in both, (IQR, 71-78 and 71-77), median WBCc at treatment onset 2.5 × 109/L (IQR, 1.6-5.8) and 2.9 × 109/L (IQR, 1.5-8.1), median bone marrow (BM) blast count 30% (IQR, 24-41%) and 49% (IQR, 30-67%), 59 (43%) and 63 (46%) patients had a secondary AML, respectively. Karyotype was evaluable in 115 and 120 patients: 80 (59%) and 87 (64%) had intermediate-risk, 35 (26%) and 33 (24%) an adverse risk karyotype, respectively. Median number of cycles delivered was 6 (IQR, 3.0-11.0) and 4 (IQR, 2.0-9.0), CR rate was 24% vs 29%, median OS and 2-year OS rates 11.3 (95% CI 9.5-13.8) vs 12.0 (95% CI 7.1-16.5) months and 20% vs 24%, respectively. No differences in CR and OS were found within the following subgroup: intermediate- and adverse-risk cytogenetic, frequency of WBCc at treatment ≥ 5 × 10^9 L and < 5 × 10^9/L, de novo and secondary AML, BM blast count < and ≥ 30%. Median DFS for AZA and DEC treated patients was 9.2 vs 12 months, respectively. Our analysis indicates similar outcomes with AZA compared to DEC.

Epidemiology of distal radius fractures: a detailed survey on a large sample of patients in a suburban area.

BACKGROUND: Literature lacks data on correlations between epidemiology and clinical data of patients with distal radius fractures (DRFs). AIM: The aim of this study was to present a detailed epidemiologic survey of a large consecutive series of patient with DRFs. MATERIALS AND METHODS: This retrospective study included 827 consecutive patients (579 females, 248 men) who sustained a DRFs in the last 5 years. All fractures were radiographically evaluated. DRFs were classified according to Association of Osteosynthesis classification. Data on age, gender, side, period in which fracture occurred, and fracture mechanism were collected. Statistical analysis was performed. RESULTS: The patients' mean age was 60.23 [standard deviation (SD) 16.65] years, with the left side being most frequently involved (56.1%). The mean age of females at the time of fracture was significantly higher than that of males. The most frequent pattern of fracture was the complete articular fracture (64.3%), while the most represented fracture type was 2R3A2.2 (21.5%). Regarding the period in which the fracture occurred, 305 DRFs (37.5%) were observed in the warmer months and 272 (33.4%) in the colder months. Low-energy trauma occurring outside home was found to be the major cause of DRF throughout the year. In both genders, trauma mechanism 2 was more frequent (59.4% F; 31.9% M; p < 0.01). A bimodal distribution of fracture mechanisms was found in males when considering the patient's age with a high-energy mechanism of fracture (3 and 4), identified in 21% (n = 52) of males aged 18-45 years, and a low-energy mechanism (1 and 2) was observed in 39.9% (n = 99) of males aged > 45 years. A significant correlation between all trauma mechanisms (from 1 to 6) and different fracture patterns (complete, partial, and extraarticular) was found (p value < 0.001). The mean age of patients with extraarticular fractures (mean age 61.75 years; SD 18.18 years) was higher than that of those with complete (mean age 59.84 years; SD 15.67 years) and partial fractures (mean age 55.26 years; SD 18.31 years). Furthermore, considering different fracture patterns and patient age groups, a statistically significant difference was found (p < 0.001). CONCLUSIONS: DRFs have a higher prevalence in females, an increase in incidence with older age, and no seasonal predisposition. Low-energy trauma occurring at home is the main cause of fracture among younger males sustaining fractures after sports trauma; Complete articular is the most frequent fracture pattern, while 2R3A2.2 is most frequent fracture type. LEVEL OF EVIDENCE: Level IV; case series; descriptive epidemiology study.

Simulation and optimization of reconstructive surgery procedures on human skin.

The complex procedures involved in the reconstructive surgery of human skin to minimize post-operative scarring are here modeled by means of an automated computational tool. A finite strain no-compression membrane model accounting for the tendency to develop wrinkling regions in the skin is presented. The constitutive behavior of the material is then described by a suitable hyperelastic incompressible potential. Transpositions of skin flaps during surgery procedures are here computationally described by a general mapping technique of the internal boundary corresponding to surgery cut. The archetypal reconstructive surgery of a Z-plasty, where a rotational transposition of the resulting triangular flaps is involved, is considered in details, along with multiple Z-plasty and rhombic flap transposition. The results are discussed in terms of optimal deformation parameters, related to stress/strain localization, displacement discontinuities and wrinkling.

Critical shoulder angle (CSA): age and gender distribution in the general population.

OBJECTIVE: Anatomical parameters and pathologies that can affect the critical shoulder angle (CSA) are subjects of discussion. To date, we do not know if the CSA value changes in the different decades of life in a population characterized by the same ethnicity, nor if there are differences related to gender or side. This study hypothesizes that age and gender may affect the CSA. METHODS: Patients older than 15 years old affected by a shoulder trauma and who were discharged with a diagnosis of shoulder contusion were enrolled. A true AP view of the shoulder was obtained as well as data regarding age and gender of all participants. The CSA was measured by three authors, and interoperator reliability was assessed. Eight subcategories, according to decades of life, were considered. Finally, the studied population was divided into three subcategories according to CSA values (< 30°; 30-35°; ≥ 35°). RESULTS: The initial sample comprised 3587 shoulder X-rays. The interobserver reproducibility was high, with an intraclass correlation coefficient of 0.865 (95% CI 0.793-0.915). Two thousand eight hundred seventy-three radiograms were excluded. The studied group comprised 714 patients [431 females, 283 males; mean age (SD): 47.2 (20.9) years, range: 11-93 years]. The mean CSA was 33.6° (range: 24-50°; SD: 3.9°). The mean CSA values in females and males were 33.7°and 33.5°, respectively. The mean CSA values of the right and left shoulders were 33.3° and 33.9°, respectively (p > 0.05). Linear regression analysis showed a CSA increase by 0.04° every year. The mean CSA in subjects aged between 15 and 19 years was significantly lower than all the other groups, except for patients older than 80 years. No significant differences were found between CSA subcategories, gender, or side. CONCLUSIONS: In the general population, the mean CSA value was 33.6°. No significant differences were found regarding the mean CSA value according to gender or side. A significant positive linear correlation between CSA and age was detected. In each decade of life, the CSA value, which is genetically determined, shows a large variability. LEVEL OF EVIDENCE: IV.

Blood glucose and epicardial adipose tissue at the hospital admission as possible predictors for COVID-19 severity.

PURPOSE: To study the possible association of CT-derived quantitative epicardial adipose tissue (EAT) and glycemia at the admission, with severe outcomes in patients with COVID-19. METHODS: Two hundred and twenty-nine patients consecutively hospitalized for COVID-19 from March 1st to June 30th 2020 were studied. Non contrast chest CT scans, to confirm diagnosis of pneumonia, were performed. EAT volume (cm3) and attenuation (Hounsfield units) were measured using a CT post-processing software. The primary outcome was acute respiratory distress syndrome (ARDS) or in-hospital death. RESULTS: The primary outcome occurred in 56.8% patients. Fasting blood glucose was significantly higher in the group ARDS/death than in the group with better prognosis [114 (98-144) vs. 101 (91-118) mg/dl, p = 0.001]. EAT volume was higher in patients with vs without the primary outcome [103 (69.25; 129.75) vs. 78.95 (50.7; 100.25) cm3, p < 0.001] and it was positively correlated with glycemia, PCR, fibrinogen, P/F ratio. In the multivariable logistic regression analysis, age and EAT volume were independently associated with ARDS/death. Glycemia and EAT attenuation would appear to be factors involved in ARDS/death with a trend of statistical significance. CONCLUSIONS: Our findings suggest that both blood glucose and EAT, easily measurable and modifiable targets, could be important predisposing factors for severe Covid-19 complications.

How lockdown measures, during COVID-19 pandemic, matter on psoriatic patient's perception: Study on 600 patients on biologic therapy.

BACKGROUND: The outbreak of coronavirus disease-2019 (COVID-19) is a public health crisis of global proportion. In psoriatic patients treated with biologic agents, evidence is not yet available on susceptibility to infection with the novel SARS-CoV-2 coronavirus, and data about the perception of COVID-19 and its impact on these patients are lacking. AIMS: The aim of this observational, spontaneous study was the evaluation of the impact of anti COVID-19 measures in "fragile population" such as patients with a chronic inflammatory disease. Thus, we evaluated the impact of perceived risk on quality of life of patients with moderate to severe psoriasis, in our outpatient clinic, and how their perceptions changed before and after the adoption of Covid-19 emergency measures following the Italian Ministerial Decree in March 9, 2020. METHODS: Using a series of questions, our study surveyed adult patients with moderate to severe psoriasis receiving treatment with biologic agents (n = 591), before and after the adoption of COVID-19 emergency measures. RESULTS: Most patients (97%) had been sufficiently informed by healthcare staff about COVID-19 spread. A significant change was observed in social activity reduction before and after the adoption of the measures (18% vs. 90% of patients; P < 0.0001). Similarly, patients were more likely to suspend ongoing therapy after the measures were adopted than before (87% vs. 34% of patients; P < 0.0001). Following the measures, older patients were significantly more inclined to suspend therapy and reduce social activities than younger patients. CONCLUSIONS: Government COVID-19 emergency measures further curtailed already reduced social activities in psoriatic patients, and led to a greater inclination to suspend biologic therapy, more so in older patients, despite there being no evidence to support this suspension. These vulnerable patients may need support from clinicians in order to maintain treatment adherence.

Fluid-solid interaction in the rate-dependent failure of brain tissue and biomimicking gels.

Brain tissue is a heterogeneous material, constituted by a soft matrix filled with cerebrospinal fluid. The interactions between, and the complexity of each of these components are responsible for the non-linear rate-dependent behaviour that characterises what is one of the most complex tissue in nature. Here, we investigate the influence of the cutting rate on the fracture properties of brain, through wire cutting experiments. We also present a computational model for the rate-dependent behaviour of fracture propagation in soft materials, which comprises the effects of fluid interaction through a poro-hyperelastic formulation. The method is developed in the framework of finite strain continuum mechanics, implemented in a commercial finite element code, and applied to the case of an edge-crack remotely loaded by a controlled displacement. Experimental and numerical results both show a toughening effect with increasing rates, which is linked to the energy dissipated by the fluid-solid interactions in the region surrounding the crack tip.

A global association between Covid-19 cases and airborne particulate matter at regional level.

Evidences of an association between air pollution and Covid-19 infections are mixed and inconclusive. We conducted an ecological analysis at regional scale of long-term exposure to air-borne particle matter and spread of Covid-19 cases during the first wave of epidemics. Global air pollution and climate data were calculated from satellite earth observation data assimilated into numerical models at 10 km resolution. Main outcome was defined as the cumulative number of cases of Covid-19 in the 14 days following the date when > 10 cumulative cases were reported. Negative binomial mixed effect models were applied to estimate the associations between the outcome and long-term exposure to air pollution at the regional level (PM10, PM2.5), after adjusting for relevant regional and country level covariates and spatial correlation. In total we collected 237,749 Covid-19 cases from 730 regions, 63 countries and 5 continents at May 30, 2020. A 10 µg/m3 increase of pollution level was associated with 8.1% (95% CI 5.4%, 10.5%) and 11.5% (95% CI 7.8%, 14.9%) increases in the number of cases in a 14 days window, for PM2.5 and PM10 respectively. We found an association between Covid-19 cases and air pollution suggestive of a possible causal link among particulate matter levels and incidence of COVID-19.

Multicentre analysis of the learning curve for laparoscopic liver resection of the posterosuperior segments.

BACKGROUND: Laparoscopic liver resection demands expertise and a long learning curve. Resection of the posterosuperior segments is challenging, and there are no data on the learning curve. The aim of this study was to evaluate the learning curve for laparoscopic resection of the posterosuperior segments. METHODS: A cumulative sum (CUSUM) analysis of the difficulty score for resection was undertaken using patient data from four specialized centres. Risk-adjusted CUSUM analysis of duration of operation, blood loss and conversions was performed, adjusting for the difficulty score of the procedures. A receiver operating characteristic (ROC) curve was used to identify the completion of the learning curve. RESULTS: According to the CUSUM analysis of 464 patients, the learning curve showed an initial decrease in the difficulty score followed by an increase and, finally, stabilization. More patients with cirrhosis or previous surgery were operated in the latest phase of the learning curve. A smaller number of wedge resections and a larger number of anatomical resections were performed progressively. Dissection using a Cavitron ultrasonic surgical aspirator and the Pringle manoeuvre were used more frequently with time. Risk-adjusted CUSUM analysis showed a progressive decrease in operating time. Blood loss initially increased slightly, then stabilized and finally decreased over time. A similar trend was found for conversions. The learning curve was estimated to be 40 procedures for wedge and 65 for anatomical resections. CONCLUSION: The learning curve for laparoscopic liver resection of the posterosuperior segments consists of a stepwise process, during which accurate patient selection is key.

ANTECEDENTES: La resección hepática laparoscópica exige experiencia y una larga curva de aprendizaje. La resección de los segmentos posterosuperiores (PS) es un reto, y no hay datos acerca de la curva de aprendizaje (learning curve, LC). El objetivo de este estudio fue evaluar la LC de la resección laparoscópica de los segmentos PS. MÉTODOS: Se realizó un análisis CUSUM de la puntuación de dificultad (difficulty score, DS) de la resección en pacientes de 4 centros especializados. La técnica CUSUM se ajustó al riesgo (risk-adjusted CUSUM, RA-CUSUM) para el tiempo operatorio, la pérdida de sangre y las conversiones a cirugía abierta ajustando según la DS de los procedimientos. Se utilizó una curva ROC para identificar el momento en el que se consideró que la LC había sido completada. RESULTADOS: De acuerdo con el análisis CUSUM de los 464 pacientes incluidos, se observó una DS baja al inicio, que posteriormente se fue incrementando hasta llegar a una estabilización. En la última fase de la LC se operaron más pacientes con cirrosis o cirugía previa. De forma progresiva se fueron reduciendo el número de resecciones hepáticas en cuña y aumentando el de resecciones anatómicas. A lo largo del tiempo se introdujo el CUSA y la maniobra de Pringle con mayor frecuencia. El RA-CUSUM mostró una reducción progresiva del tiempo operatorio. La pérdida de sangre inicialmente aumentó ligeramente, luego se estabilizó y finalmente disminuyó con el tiempo. Una tendencia similar se observó para las conversiones. La LC se estimó en 40 casos para las resecciones en cuña y en 65 casos para las resecciones anatómicas. CONCLUSIÓN: La LC de la resección hepática laparoscópica de los segmentos PS es un proceso paso a paso durante el cual la selección del paciente es clave.

Associations between the chemokine biomarker CCL2 and knee osteoarthritis outcomes: the Johnston County Osteoarthritis Project.

OBJECTIVE: Our study analyzes the association between chemokine-ligand-2 (CCL2) serum concentrations at baseline and knee radiographic osteoarthritis (OA) (knee-rOA), knee-rOA progression, individual radiographic features and knee symptomatic OA at 5-year follow-up. DESIGN: OA outcomes were analyzed in a community-based cohort including a baseline enrollment and a 5-year follow-up. Baseline CCL2 serum concentrations were assessed by multiplex assay and associated with presence or progression of individual radiographic features at 5-year follow-up. Separate multiple logistic regression models were used to examine adjusted associations between baseline CCL2 and each of the knee OA variables at follow-up. CCL2 at baseline was modeled as an explanatory variable, whereas each of the knee OA variables at follow-up served as the response variables. Models were adjusted for age, BMI, race, and sex. Trend tests were conducted to assess any linear effect on outcomes across CCL2 tertiles. RESULTS: Participants (n = 168) had a median age of 57-years and median BMI of 29 kg/m2. About 63% of all participants were women, and 58% Caucasian (42% African American). In adjusted logistic models, continuous log-CCL2 was significantly associated with knee-rOA. For each unit increase in log CCL2, the odds of having knee-rOA at follow-up was increased by 72%. CCL2 tertiles showed significant linear associations with presence and progression of knee-rOA and medial joint space narrowing (JSN), but not with presence or progression of osteophytes, bone sclerosis, knee symptoms, or symptomatic knee-rOA. CONCLUSIONS: Serum CCL2 may help to elucidate some mechanisms of joint destruction and identify individuals with higher odds of structural knee changes.

Role of the C-C chemokine receptor-2 in a murine model of injury-induced osteoarthritis.

OBJECTIVE: We previously found in our embryonic studies that proper regulation of the chemokine CCL12 through its sole receptor CCR2, is critical for joint and growth plate development. In the present study, we examined the role of CCR2 in injury-induced-osteoarthritis (OA). METHOD: We used a murine model of injury-induced-OA (destabilization of medial meniscus, DMM), and systemically blocked CCR2 using a specific antagonist (RS504393) at different times during disease progression. We examined joint degeneration by assessing cartilage (cartilage loss, chondrocyte hypertrophy, MMP-13 expression) and bone lesions (bone sclerosis, osteophytes formation) with or without the CCR2 antagonist. We also performed pain behavioral studies by assessing the weight distribution between the normal and arthritic hind paws using the IITS incapacitance meter. RESULTS: Testing early vs delayed administration of the CCR2 antagonist demonstrated differential effects on joint damage. We found that OA changes in articular cartilage and bone were ameliorated by pharmacological CCR2 blockade, if given early in OA development: specifically, pharmacological targeting of CCR2 during the first 4 weeks (wks) following injury, reduced OA cartilage and bone damage, with less effectiveness with later treatments. Importantly, our pain-related behavioral studies showed that blockade of CCR2 signaling during early, 1-4 wks post-surgery or moderate, 4-8 wks post-surgery, OA was sufficient to decrease pain measures, with sustained improvement at later stages, after treatment was stopped. CONCLUSIONS: Our data highlight the potential efficacy of antagonizing CCR2 at early stages to slow the progression of post-injury OA and, in addition, improve pain symptoms.

Bilateral hand squamous-cells carcinoma in patient affected with non-Hodgkin lymphoma. Case report and literature review.

BACKGROUND: Squamous-cell skin cancer is the most frequent tumor in the hand. It occurs on sun-damaged skin, especially in lightskinned individuals with a long history of chronic sun exposure. CASE REPORT: We describe a case of bilateral hand squamous-cell carcinoma in a elderly patient affected with non-Hodgkin's lymphoma, who underwent several non-successful surgical treatment, radiotherapy and at the least, amputation of right hand for rapid clinical evolution after radiotreatment. Available literature on the subject has been reviewed. RESULTS: In our case, after several non-successful treatment, elective amputation at the distal third of forearm was performed. We reviewed 56 items including books, original articles, reviews, cases report. CONCLUSIONS: Current evidence on treatment of hand squamouscells carcinoma is to perform a first radical surgical treatment in order to avoid recurrence/metastasis and to achieve a safer level of amputation thus increasing the surface area of healthy tissue available for eventually subsequent reconstruction/prosthesization.

Caustic burn caused by intradermal self administration of muriatic acid for suicidal attempt: optimal wound healing and functional recovery with a non surgical treatment.

BACKGROUND: Caustic burns are burns of third and fourth degree caused by strong acids or strong bases. Muriatic acid is often used for suicidal attempt by ingestion. We describe a case of a caustic skin lesion caused by intravenous failed attempt of suicide by injection of Muriatic acid in a woman affected with bipolar-syndrome. Generally, caustic burns are treated by cleansing, escarectomy and coverage with skin grafts. CASE REPORT: We treated the patient with a non invasive technique with collagenase and hyaluronic acid sodium salt cream (Bionect start®), hyaluronic acid-based matrix (Hyalomatrix®) and Vacuum-Assisted Closure (VAC) Therapy®. RESULTS: We obtained complete healing in 6 weeks. CONCLUSIONS: Combined use of non invasive techniques seems to ensure only advantages for both the patients and the Health System. It reduces health care costs and risks for the patients such as nosocomial infections. Patient's compliance is high, as its quality of life. Complete healing of the wound is fast and recovery of function is full.

High prevalence of symptoms in a severely abused "non-patient" women population.

OBJECTIVE: The objective of this article is to assess the prevalence of somatic symptoms and of gastrointestinal (GI) syndromes in abused "non-patient" women and the association with the time of perpetration, type, and severity of abuse. METHODS: Sixty-seven women, 18-58 years, receiving shelter in anti-violence associations were invited to fill out an anonymous questionnaire with a medical and an abuse section. The severity of abuse was expressed as the 0-6 Abuse Severity Measure (ASM). The association between abuse characteristics and the number of symptoms, and GI syndromes was assessed by Poisson regression model. RESULTS: Most women suffered from childhood and adulthood sexual and physical abuse. They reported a mean of 5.1 GI symptoms (range 0-13; median 5; IQR 6) and of 1.3 extra-GI symptoms (range 0-6; median 1; IQR 2); 30% of women matched the Rome II Criteria for one, 36% for two, and 4.4% for three or more syndromes, respectively. Women with an ASM of 5-6, having suffered from both sexual and physical abuse, reported significantly (p = 0.02) more GI symptoms, but not extra-GI ones (p = 0.07), and met criteria for more GI syndromes than women with an ASM ≤4 and those reporting only one type of abuse. No association was found between the time of perpetration of the abuse and the number of GI and extra-GI symptoms. CONCLUSIONS: Symptoms in abused "non-patient" women mainly concern the abdomen and the GI tract. A history of severe, combined physical and sexual abuse is associated with a higher number of GI symptoms.

Evaluation of the impact of writing exercises interventions on quality of life in patients with psoriasis undergoing systemic treatments.

BACKGROUND: Emotional writing is a short-term psychological intervention that has been successfully used in several controlled studies. OBJECTIVES: The overall objective of the study was to test the efficacy of Pennebaker's emotional writing intervention in patients with psoriasis treated with systemic therapy. METHODS: A randomized controlled trial was conducted in seven clinical centres in Italy, over a 2-year period. The main outcome measures were the psoriasis area and severity index and the Physician Global Assessment, as well as generic and dermatology-specific quality of life questionnaires. Such outcomes were measured at 4 weeks, and 6 and 12 months from baseline. The project recruitment time was 12 months, and the total follow-up time for each individual was also 12 months. RESULTS: In total, 202 patients were enrolled and assessed at baseline, 67 of whom completed all three follow-up visits. The writing exercise had little or no effect on patients with psoriasis who were undergoing systemic treatment. In the Generalized Estimating Equations models no statistically significant differences were observed in the Pennebaker intervention group vs. the control group. In subgroup analysis for health status, small effects in favour of patients assigned to the Pennebaker group were documented at the end of the study in women, in overweight individuals, in patients under treatment with biological drugs, and on the Physical Component Summary of the Short Form of the Medical Outcomes Study Questionnaire. CONCLUSIONS: The Pennebaker and control groups had similar changes over time for practically all the outcome variables, and also when considering all observations and adjusting for all the variables of interest. The longitudinal analysis confirmed that the intervention had little or no effect on the variables of interest. The implementation of writing exercises requires a careful and ad hoc organization, including dedicated spaces for the writing itself.

Masson's tumor: a soft tissue tumor simulating a tendon cyst: case report.

INTRODUCTION: Intravascular papillary endothelial hyperplasia (Masson's hemangioma or Masson's tumor) is a benign vascular disease with an exuberant endothelial proliferation in normal blood vessels. Although relatively uncommon, its correct diagnosis is important because it can clinically be like both benign lesions and malignant neoplasms. We present a case of intravascular proliferative endothelial hyperplasia simulating a tendon cyst both clinically and on ultrasound. CASE REPORT: A 74-year old Caucasian female presented with a 4-month history of soreness and swelling in the fourth finger of the right hand. Ultrasound showed an oval mass with fluid content, referred to a tendon cyst. A wide surgical excision was subsequently performed. The final histological diagnosis was Masson's tumor. DISCUSSION: The pathogenesis of intravascular papillary endothelial hyperplasia is still unclear but the exuberant endothelial cell proliferation might be stimulated by an autocrine loop of endothelial basic fibroblast growth factor (bFGF) secretion. There are three types of papillary endothelial hyperplasia: primary, or intravascular; secondary, or mixed; and extravascular. The main differential diagnosis is against pyogenic granuloma, Kaposi sarcoma, hemangioma, and angiosarcoma. CONCLUSIONS: Masson's tumor can be like both benign lesions and malignant neoplasms clinically and on ultrasound. For this reason, the right diagnosis can be made only by histology, which reveals a papillary growth composed of hyperplastic endothelial cells supported by delicate fibrous stalks entirely confined within the vascular lumen.

Disease severity evaluation among dermatological out-patients: a comparison between the assessments of patients and physicians.

BACKGROUND: The assessment of a patient's disease severity is an essential component in the formulation of treatment strategies. OBJECTIVES: To compare disease severity assessment by patients and by physicians, and to describe the possible discrepancies between them. METHODS: For each patient, we obtained the Physician Global Assessment (PhGA) and the Patient Global Assessment (PtGA). Data were completed for 2.578 patients. Sixty-one physicians participated in the study. We calculated the agreement between PtGA and PhGA scores using the weighted kappa statistics; a multinomial logistic regression was performed to assess the risk of disagreement considering both patient and physician variables. RESULTS: Differences in the percentages of severity level, identified by patients and by physicians, were always statistically significant (P < 0.05). Overall, the weighted Cohen's kappa was in the range of 0.09-0.34, depending on the diseases. Gender differences between patients and physicians did not influence the agreement. In the multinomial model female patients (OR = 1.38; 95% CI, 1.07-1.77), patients with higher educational levels (OR = 2.71; 95% CI, 2.12-3.46), and patients with impaired quality of life (OR = 1.56; 95% CI 1.23-1.97) had a higher risk to be underestimated for their disease severity by physicians, independently by physician gender and experience. CONCLUSIONS: Combining the subjective report with the objective severity assessment of the lesions, dermatologists may reach a better determination of how severity of disease is perceived by their patients and how they feel about the effectiveness of treatment. PtGA and PhGA might be considered in routine clinical assessments and not only for research activities.

Extensive facial trauma caused by dog bites in woman suffering from systemic fluconazole-resistant Candida infection.

INTRODUCTION: Dog bites present a complex problem. Extensive facial trauma is a challenging problem to treat with priority for functional outcome. This paper describes the conservative treatment in a very difficult case of facial trauma with unusual infections due to the bites. CASE REPORT: A 45 year-old woman was admitted in hypovolaemic shock with amputation of nose, upper and lower lips, left cheek and chin caused by dog bites. After vital parameters and volaemy were stabilized, wound toilet was performed, followed by skin and mucosal rotation flaps and anterior nasal tamponade; the lesion has then been covered with a collagen/oxidized regenerated cellulose dressing and sterile gauzes. Culture test highlighted coagulase-negative Staphylococcus and Candida albicans. However after few days, the patient developed septic-undulant hyperpyrexia, retinitis, renal candidiasis, folliculitis. Systemic Candida infection resistant to fluconazole was diagnosed. Amphotericin B was given to the patient and the facial wound was managed conservatively with an active medication because of inoperability conditions. The outcome of the use of active medications was an immediate response with excessive granulation tissue followed by a rapid re-epithelization. CONCLUSION: As our case has shown, conservative treatment can be a valid alternative therapy in the treatment of large wounds with invasive candidosis and candidaemia or other major contraindications to surgery. In fact, in cases where surgical reconstruction is not a feasible option, conservative treatment can allow a rapid repair of the skin barrier.

Assessment of the health status of 2,499 dermatological outpatients using the 12-item Medical Outcomes Study Short Form (SF-12) questionnaire.

BACKGROUND: In dermatological research and clinical practice it is important to evaluate the burden of the disease. OBJECTIVE: To assess whether the 12-item Short Form of the Medical Outcomes Study (SF-12) could yield a valid description of the health status of a large number of dermatological outpatients. METHODS: The SF-12 and the 12-item General Health Questionnaire (GHQ-12) were utilized. Questionnaires were self-completed by the outpatients in the waiting rooms. At the end of the visit the dermatologists recorded the diagnosis and the evaluation of the clinical severity. RESULTS: Data were complete for 2499 patients. We observed a reduction in the Physical Component Summary score (PCS-12) with increasing age, while the Mental Component Summary score (MCS-12) was stable. PCS-12 and MCS-12 scores were worse in women. Twenty-three per cent of patients were identified as GHQ-12 positive. GHQ-12-positive patients ('cases') had lower PCS-12 and MCS-12 scores compared with GHQ-12-negative patients (mean ± SD, PCS-12: 47·9 ± 10·8 vs. 52·2 ± 6·6; MCS-12: 35·2 ± 10·2 vs. 50·9 ± 78·3, respectively). High correlations between the MCS-12 score and the GHQ-12 were documented overall (-0·690, P < 0·001) and for single skin diseases. CONCLUSIONS: The impact of dermatological diseases is high for the mental components of health status; the mean scores for MCS-12 were low, and lower in patients identified as GHQ-12 'cases'. The picture of the general health status of patients with skin diseases given by the SF-12 allows meaningful comparisons both within dermatological conditions and with diseases in other specialties, as well as within categories of clinical severity and psychological well-being in single skin conditions.
