How to dramatically reduce dehydration-related readmission in patients undergoing restorative surgery with diverting ileostomy for ulcerative colitis.

BACKGROUND: Patients affected by ulcerative colitis (UC) often require surgery, involving two or three-stage procedures, including ileostomy creation. While ileostomy has some advantages, it can lead to complications, such as dehydration. The aim of this study was to evaluate the impact of a new individualized stoma-therapeutic-care-pathway (STCP) on dehydration-related readmissions. Secondary endpoints were stoma-related complications. METHODS: The study compares two series of consecutive patients with UC undergoing diverting ileostomy during restorative ileo-pouch-anal-anastomosis. The STCP group consists of patients enrolled from January 2020 to December 2021 who followed the pathway. The older group was selected from 2015 to 2017 (control group). Clinical data were collected, including patient characteristics, hospital stay, complications, and readmissions. The study was approved by the local institutional review board. RESULTS: Overall, 30-day dehydration-related readmission occurred in one (1.4%) versus nine (15.3%) patients in the STCP group versus control group, respectively (p = 0.005). In-hospital peristomal skin complications were significantly lower in STCP group (6 patients, 8.5%) versus control (35, 59.3%), as well as ostomy complications that occurred in 5 (7%) patients in the STCP group versus 8 (13.5%) in the control group (both p < 0.001). Ostomy complications reduced significantly in the STCP group after discharge (two patients, 2.8% versus eight, 13.5%), p = 0.001, and after 30-days (three patients, 4.2% versus five, 8.5%). CONCLUSIONS: This study underscores the effectiveness of STCP in reducing dehydration-related readmissions and stoma-related complications in patients with UC undergoing stoma creation. It emphasizes the significance of patient education, close follow-up, and multidisciplinary care. Further research and standardized stoma education are essential.

Medial and lateral exostoses of the distal phalanx of the hallux: A potentially painful bunion-like structure. Part 1: Incidence and clinical application.

BACKGROUND: Exostoses at the base of the distal phalanx of the great toe are usually asymptomatic. The literature has not generally considered them as the origin of a possible problem resulting from a pressure conflict between hallux and shoe (medial aspect) or second toe (lateral aspect) nor a potential complication of surgical correction of hallux valgus deformity. No studies, to our knowledge, have evaluated its possible correlation with other foot disorders. When one of these neglected exostoses became painful after surgical correction of hallux valgus, we decided to start a study to determine their possible origin, prevalence in daily practice and histo-pathological morphology. METHODS: Two hundred and fifty-four feet of patients (average age 41.7y.) were enrolled in the study from January 2007 to June 2009. Dorsoplantar weight-bearing radiographs were used to analyze the presence of exostoses and their correlation with the distal phalanx morphology, metatarsal formula (or transverse plane orientation of the metatarsal heads parabola) and hallux valgus angles. Patients were classified according to their age and main symptom for consultation. Four exostoses removed from cadaver feet were also analyzed microscopically. RESULTS: Osseous excrescences arising on the medial or lateral aspect at the proximal part of the terminal phalanx of the hallux were observed in 132 feet (51.9%). Thirty-five feet out of these 132 (13.7%) had exostoses on both sides of the phalanx.A statistically significant positive correlation was found between the presence of a medial exostosis of the phalanx and the severity of HVA. Patients with higher IPH and asymmetry angles have a lower prevalence of medial exostoses (p<0.05). Amongst the different morphologies of the second phalanx, exostoses were most likely found in the standard form. CONCLUSIONS: Prevalence of exostoses at the base of the distal phalanx is high (51.9% of the studied feet). Histological findings would suggest that these exostoses could be considered a mechanical reactive process, produced by a chronic irritation by shoes. We encourage surgeons to be aware of its potential clinical implications. Direct resection is very simple and the most appropriate treatment for symptomatic cases.

Inflammatory biomarkers and intellectual disability in patients with Down syndrome.

BACKGROUND: Intellectual disability (ID) is part of the Down syndrome (DS) phenotypic spectrum, but the exact molecular pathophysiology of ID in individuals with DS is not yet fully understood, with many research hypotheses still unproven. Basing on previous studies (which suggested a possible role of altered inflammatory response in DS-related ID), we assessed the serum levels of a number of inflammatory biomarkers [serum amyloid A (SAA), C-reactive protein (C-RP), high mobility group box-1 (HMGB1)] in a cohort of individuals with DS and healthy controls. METHODS: In total, 24 children diagnosed with DS and 12 healthy controls were enrolled, and all underwent detailed cognitive assessment. Also, serum SAA, C-RP and HMGB1 levels were measured in all recruited subjects and correlated to the severity of ID in the DS group. RESULTS: Serum SAA, C-RP and HMGB1 values were found to be significantly higher in the DS group compared with the healthy subjects (P = 0.001). In addition, serum HMGB1 levels positively correlated with C-RP and SAA in the DS group but not in the healthy controls. Only serum C-RP levels resulted inversely correlated (P < 0.01) with intelligence quotient (IQ); conversely, significant statistical correlations between serum SAA levels and IQ (as well as between HMGB1 and IQ) have been not found (P > 0.05). CONCLUSIONS: The levels of the determined markers were higher in DS individuals compared with (cognitively) healthy subjects, and CRP showed a negative correlation with IQ in children with DS.

[The United Nations conventions on the rights of persons with disabilities: which strategies for protection at work?]. / La convenzione O.N.U. sui diritti delle persone con disabilità: quali strategie per la tutela sul lavoro?

More than 15% of the world's population lives with some form of moderate or severe disabilities, a growing percentage due to aging population as well as to the global increase of chronic diseases. The United Nations approved, in December 2006, the "Convention on the Rights of Persons with Disabilities" which dealt with the theme "work and employment". It prohibited discrimination on the grounds of disability with regard to health and safety at work, ensuring safe and healthy working conditions including protection from harassment. The most important expectation for the UN Convention, ratified in Italy by law 18/2009, is the guarantee that disable people in the workplaces are provided with "reasonable accomodation". This term refers to modifications and adaptations which are necessary and appropriate, that do not foresee excessive costs, to be taken, where necessary, to ensure even workers with disabilities the enjoyment and exercise of all their rights.

Influence of total hip arthroplasty and physicians advices in the sports activity performed after the surgery. / Influencia de la artroplastia total de cadera y el consejo médico en la actividad deportiva realizada después de la intervención.

BACKGROUND AND OBJECTIVES: There are no randomized prospective studies that evaluate sports activity after total hip arthroplasty (THA). The objective of this study is to assess the level and type of sports activity in patients undergoing THA and to assess the recommendations given by physicians. MATERIALS AND METHODS: We performed a descriptive study that analyzes 46 patients (the average age was 41 years, range 37 - 48) under 50 years of age who underwent THA (58 hips) in our center. The average follow-up was 7.5 (1 - 11) years. Age, sex, sports activity according to the UCLA scale, sports activities practiced before and after the intervention, complications and recommendations given by doctors were evaluated. RESULTS: The average time to resume sport activity after the surgery was 5 (3-10) months. There were no differences in the UCLA scale before and after the operation (P> 0.05). The most practiced sport before the surgery was swimming (17%). The 31% of patients did not receive advice from their physician and the 65.2% were dissuaded from playing sports after ATC. The recommended sports were swimming (44%) and the static bicycle (17.5%), correlating with the most practiced sports after the operation. CONCLUSION: The patients modified their sport activity after having undergone a total hip arthroplasty. The surgery and the physician's advice were the ones that influenced the choice of the sports activity performed after being operated on.

Serum interleukin-6 levels are increased in HIV-infected patients that develop autoimmune disease during long-term follow-up.

BACKGROUND: Elevated IL-6 levels have been associated with both autoimmune diseases and treated HIV-seropositive (HIV+) subjects. However, few data on classic and trans-signaling IL-6 in autoimmune thyroid diseases and HIV+ subjects developing autoimmune disorders are currently available. MATERIALS AND METHODS: A total of 102 patients were included in the study. They were subdivided into two groups. Group A consisted in 51 HIV+ patients, who were followed-up for a period of five years in search of possible occurrence of autoimmune diseases. Ten of them, treated with antiretroviral therapy (ART), developed an autoimmune disorder, namely Hashimoto's thyroiditis, and psoriasis. Group B consisted in 51 patients affected by Hashimoto's thyroiditis (HT). Serum levels of the free form of IL-6 were analyzed by ELISA in all patients and for HIV+ patients at the beginning of the follow-up, before initiation of ART. RESULTS: Mean serum levels of IL-6 were similar in Group A and in Group B. In Group B, IL-6 levels showed a 5.8% increase compared with assay minimum detectable dose corresponding to 1% of full serum IL-6 level. However, serum levels of free IL-6 were increased in those HIV+ patients who developed autoimmune disorders (5.8±2.8pg/ml) and in these patients, the highest levels of free IL-6 correlated with age and CD4 cellular counts. CONCLUSIONS: The present study indicates a correlation between serum free IL-6 levels and the occurrence of autoimmune disease in HIV+ population, treated with ART during a long-term follow-up. The increased levels of serum free IL-6 were observed before ART treatment was initiated, indicating that IL-6 measurement in such patients may represent an early predictor of development of autoimmune disease.

Diagnosis and treatment of depression in Alzheimer's disease: impact on mood and cognition.

Depression, a common neuropsychiatric syndrome associated with lower quality of life (QOL), higher mortality, and higher caregiver burden, is estimated to occur in 20-50% of Alzheimer's disease (AD) patients. Recent research suggests that depression in AD (dAD) may differ from major depression phenomenologically and etiologically. Treatment options for dAD include behavioral modifications, pharmacotherapy, and electroconvulsive therapy. Successful treatment of dAD has been reported to improve patients' mood and QOL, as well as lower caregiver burden. Further research is needed in therapeutics of dAD to enhance treatment options and effectiveness.

[Migration, work flexibility and early retirement of nurses in Italy]. / Immigrazione, flessibilità e ritiro precoce nel personale infermieristico in Italia.

Several work organizational changes have been occurring in the health sector in the last years. Workforce is rapidly changing and particularly nurses. In Italy there is a growing shortage of nurses (5,4/1000 inhabitants versus 9,26 in EU25) due mainly to early retirement and insufficient turnover of nurses coming from educational programmes. Work flexibility and facilitation of migration flow of foreigner nurses have been introduced in Italy to face the problem. The present study is aimed at investigating the impact of such a change in the nursing sector in Italy and its possible impact on occupational safety and health. In view of this, the main institutional and category Sources were used. According to IPASVI estimates, the shortage of nurses in Italy is 99,000. Out of a total of 342,000 active professional nurses, 20,000 are foreign, mainly from European countries. Nurses are specially affected by accidents at work, mainly musculoskeletal disorders. The study shows a higher vulnerability of migrated nurses and nurses hired through cooperatives. Therefore urgent measures are needed to promote their integration and assess educational and training needs in the field of health and safety at work.

[In vitro activity of voriconazole against yeast and algae isolates according to new resistance pattern cut-off points]. / Actividad in vitro del voriconazol frente a levaduras y algas con los nuevos puntos de corte del patrón de resistencia.

Voriconazole is a second-generation triazole derived from fluconazole but with greater potency and spectrum of activity, showing good in vitro activity against Candida, Cryptococcus and Aspergillus species, and other filamentous and dimorphic fungi. It can be administered orally or intravenously. It was initially approved in 2002 by the U.S. Food and Drug Administration as a treatment option for invasive aspergillosis and Fusarium and S. apiospermum infections showing resistance or intolerance to other antifungals; later on, it also received approval in the United States and Europe as a treatment option for esophageal candidiasis; candida infection in non-neutropenic patients; disseminated candidiasis of skin, abdomen, kidney and bladder; and injuries. Recently, the Clinical Laboratory Standard Institute established some provisional break points for voriconazole, classifying isolates with an MICor=4 mg/l as resistant. In line with these new data, we performed a systematic review of literature on in vitro activity of voriconazole against yeast and algae isolates, and compared it to that of fluconazole and itraconazole. The review included a total of 27,340 yeast isolates, 24,177 of Candida species, 2,726 of Cryptococcus species, 453 of other species, and 104 Prototheca. The yeast isolates resistant to voriconazole is approximately 1%, and 71% of fluconazole-resistant isolates are susceptible to voriconazole.

[Health risks associated with child labor: activities and proposals of WHO collaboration centers]. / Rischi per la salute connessi al lavoro minorile: attività e proposte dei centri di collaborazione dell'OMS.

Child labour should be analyzed with regard to the main frameworks where it arises: particularly, the small family based enterprises in agricultural, hospitality and restaurateurs' sectors play a leading role. In these contexts the child can underestimate the risks related to the carried out work activity and assimilate the work background to the family background. In spite of the national thorough regulations on child labour, the network of WHO Collaborating Centres is working to develop a common awareness in order to evaluate, communicate and prevent the occupational health and safety risks for children, at national and international level.

[Bone transplant]. / Trasplante óseo.

We describe the methodology of the Bone and Soft Tissue Bank, from extraction and storage until use. Since the year 1986, with the creation of the Bone Bank in the University Clinic of Navarra, more than 3,000 grafts have been used for very different types of surgery. Bone grafts can be classified into cortical and spongy; the former are principally used in surgery to save tumour patients, in large post-traumatic reconstructions and in replacement surgery where there are massive bone defects and a structural support is required. The spongy grafts are the most used due to their numerous indications; they are especially useful in filling cavities that require a significant quantity of graft when the autograft is insufficient, or as a complement. They are also of special help in treating fractures when there is bone loss and in the treatment of delays in consolidation and pseudoarthrosis in little vascularized and atrophic zones. They are also used in prosthetic surgery against the presence of cavity type defects. Allografts of soft tissues are specially recognised in multiple ligament injuries that require reconstructions. Nowadays, the most utilised are those employed in surgery of the anterior cruciate ligament although they can be used for filling any ligament or tendon defect. The principal difficulties of the cortical allografts are in the consolidation of the ends with the bone itself and in tumour surgery, given that these are patients immunodepressed by the treatment, the incidence of infection is increased with respect to spongy grafts and soft tissues, which is irrelevant. In short, the increasingly widespread use of allografts is an essential therapeutic weapon in orthopaedic surgery and traumatology. It must be used by expert hands.

Staple Line Reinforcement During Laparoscopic Sleeve Gastrectomy: Absorbable Monofilament, Barbed Suture, Fibrin Glue, or Nothing? Results of a Prospective Randomized Study.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is associated with serious complications, such as staple line (SL) leaks and bleeding. In order to prevent the occurrence of these complications, surgeons have advocated the need to strengthen the staple line. The aim of this randomized controlled study was to compare the efficacy of three different ways of strengthening of the SL in LSG in preventing surgical post-operative complications. METHODS: Between April 2012 and December 2014, 600 patients (pts) scheduled for LSG were prospectively randomized into groups without SL reinforcement (group A) or with SL reinforcement including fibrin glue coverage (group B), or oversewn SL with imbricating absorbable (Monocryl™; group C) or barbed (V lock®) running suture (group D). Primary endpoints were post-operative leaks, bleeding, and stenosis, while secondary outcomes consisted of the time to perform the staple line reinforcement (SLR) and total operative time. RESULTS: Mean SLR operative time was lower for group B (3.4 ± 1.3 min) compared with that for groups C (26.8 ± 8.5 min) and D (21.1 ± 8.4 min) (p < 0.0001). Mean total operative time was 100.7 ± 16.4 min (group A), 104.4 ± 22.1 min (group B), 126.2 ± 18.9 min (group C), and 124.6 ± 22.8 (group D) (p < 0.0001). Post-operative leaks, bleeding, and stenosis were recorded in 14 pts (2.3 %), 5 pts (0.8 %), and 7 pts (1.1 %), respectively, without statistical difference between the groups. CONCLUSION: Our study suggests that SLR during LSG, with an imbricating or non-imbricating running suture or with fibrin glue, is an unrewarding surgical act with the sole effect of prolonging the operative time.

Paclitaxel and radiotherapy: sequence-dependent efficacy--a preclinical model.

The optimal sequence of a paclitaxel-radiation combination was investigated in vitro in two human colon adenocarcinoma cell lines, HT29 and LoVo. Three schedules of combined treatment were tested by clonogenic and flow cytometric assays. Paclitaxel was given 24 h prior to a single radiation shot (first schedule) or 24 h (second schedule) or 48 h (third schedule) before 3 days of concomitant radiation. Dose-response data were fit to a linear quadratic model, and mean inactivation dose and sensitizer enhanced ratio were calculated. In HT29 cells, the first and second schedule resulted in an additive effect, whereas a supraadditive interaction was observed with the third combination schedule. This effect was obtained with amounts of paclitaxel lower than IC50, which did not result in cell cycle perturbation, and with low radiation dose (2 Gy) that may be given in a clinical setting. LoVo cells were less sensitive to combined treatment than HT29 cells, switching from infraadditive (first and second schedule) to additive interaction (third schedule). Posttreatment recovery studies of third schedule showed a loss of cell survival in HT29 cells but not in LoVo cells. In contrast to LoVo cells, the third schedule in HT29 cells was able to induce perturbation of cell cycle kinetics, an effective impairment of DNA repair, and apoptotic cell death. HT29 and LoVo cells showed constitutional different characteristics: HT29 cells were more sensitive to paclitaxel exposure, less radiosensitive, and had a different cell cycle redistribution after radiation exposure than LoVo cells; moreover, HT29 cells showed a major propensity to undergo apoptosis. These results suggest that the radiosensitizing effect of paclitaxel was strictly schedule dependent, and the inhibition of DNA repair, cell cycle redistribution, and apoptosis could be the mechanisms for the induction of radiosensitization by paclitaxel.

Infectious syphilis mimicking neoplastic disease.

Five patients who were initially evaluated for malignant neoplasm actually had infectious syphillis (one primary, two secondaries, two secondaries with persistence of primary). Two patients were considered for radical surgery and one for extensive radiation and/or chemotherapy. In four patients an elevated routine admission VDRL was the first indication of the correct diagnosis. Dark-field examination is the most important laboratory test in the diagnosis of primary syphillis; VDRL and FTA-ABS are most important in confirming secondary syphillis. Penicillin remains the drug of choice for therapy. At a time when the incidence of sexually transmitted diseases is increasing, it is extremely important to develop adequate educational programs for medical students and physicians.

Differences of vascular endothelial growth factor (VEGF) expression between liver and abdominal metastases from colon cancer. Implications for the treatment with VEGF inhibitors.

The vascular endothelial growth factor (VEGF) plays a central role in promoting angiogenesis, and it is the target of innovative anti-cancer therapies. In colorectal carcinomas, differences in the VEGF expression have been found between the primary tumor and its metastases. We postulated that differences in the VEGF expression may also exist between liver and abdominal metastases from colon cancer. Consecutive colon cancer patients with liver or abdominal metastases were considered eligible for the study. Biopsies had to be performed before chemotherapy and the VEGF analysis were conducted through immunohistochemistry. The staining results were correlated to the metastatic pattern. The study population consisted of 41 patients with a metastatic site in the liver in 19 patients and the abdomen in 22 patients. A positive VEGF staining was found in 19 of the 41 metastatic samples (46%). Cases with positive VEGF expression were found more frequently in abdominal (15 out of 22 patients; 68%) than in liver metastases (4 out of 19 patients; 21%). Also, the degree of VEGF immunoreactivity was significantly higher in abdominal than in liver metastases. Evidence is supported that the VEGF expression may be different between colon cancer metastatic sites. The efficacy of anti-VEGF treatments may depend on the VEGF expression status, and this finding deserves further investigation.

The in-vitro transformation of [3H]dehydroepiandrosterone into its principal metabolites in the adrenal cortex of adult castrated male rats and following steroid treatment.

The adrenal gland of castrated adult male rats metabolized [3H]dehydroepiandrosterone in vitro to delta 4-androsten-3,17-dione (4AD), testosterone, dihydrotestosterone (DHT) and 5 alpha-androstane-3,17-dione (5 alpha AD). Despite the low testosterone values, DHT and 5 alpha AD were higher 30 and especially 60 days after castration, with raised 4AD:testosterone and decreased testosterone:DHT ratios. The 5 alpha-reductase activity thus appears to increase with time after castration. Fourteen days after castration, 4AD was the only metabolite that was raised compared with intact animals, and testosterone was comparable in sham-operated and castrated rats. The administration of testosterone propionate to castrated rats restored testosterone values to those of intact rat adrenals, whereas 4AD values were greater. The administration of dihydrotestosterone propionate also yielded higher levels of 4AD, in the presence of a lower testosterone value. After administration of oestradiol benzoate, 4AD values were lower especially compared with the other hormone-treated groups, and there was an unexpectedly high testosterone value. These data indicate that the adrenal gland contributes to the production of androgens, as previously noted by Andò, Canonaco, Beraldi et al. (1988) who showed increased plasma 4AD and testosterone levels in adult male rats 30 days after castration. Furthermore, adrenal androgen production in castrated animals is differentially regulated by sex steroids.

Olanzapine therapy in treatment-resistant psychotic mood disorders: a long-term follow-up study.

BACKGROUND: Recent studies suggest a role for the atypical antipsychotic olanzapine in the acute treatment of psychotic mood disorders, but long-term data are unavailable. The purpose of this naturalistic study was to determine the long-term effectiveness and tolerability of olanzapine as add-on therapy in psychotic mood disorders. METHOD: Hospital records were reviewed for 125 inpatients at the state psychiatric hospital in Buffalo, N.Y., who received at least 6 weeks of add-on olanzapine treatment for psychotic mood disorders (schizoaffective disorders [bipolar and depressive type], bipolar disorders [I, II, and NOS], and major depressive disorder). A group of schizophrenic patients served as a control group (N = 50). Baseline measures, including age, gender, number of hospitalizations in the 2 years prior to olanzapine treatment, concomitant medications, the Clinical Global Impressions scale (CGI), and the Global Assessment of Functioning-Equivalent (GAF-EQ) and Kennedy Axis V psychological impairment, violence, social skills, and activities of daily living subscale scores, were obtained. Follow-up information was obtained from the patients at least 6 months after initiation of olanzapine or by chart review and discussion with the treating psychiatrist. Patients with a diagnosis of psychotic mood disorders were compared with patients with the non-affective psychotic disorder (schizophrenia) on a variety of outcome measures. RESULTS: Follow-up information was available on 102 patients (82%). Mean follow-up was 15 months; 50 (49%) of the 102 patients remained on olanzapine treatment at follow-up (32 psychotic mood disorder, 18 schizophrenic). The primary reason for discontinuation in both groups was lack of response. Both the psychotic mood disorder and schizophrenic groups had comparable outcomes on the CGI and GAF-EQ. Improvement on the Kennedy Axis V psychological impairment and social skills subscales was seen only in the psychotic mood disorders group (p < .01); both groups showed significant (p < .02) improvement in the violence subscale. Sustained mood-stabilizing effect was evident in only 7/27 (26%) of the psychotic mood disorders patients continuing on add-on olanzapine treatment at follow-up. CONCLUSION: Lack of response was the primary reason for discontinuation of add-on olanzapine in both groups. Mood symptoms predicted a better response to add-on olanzapine in patients with psychotic mood disorders on selective outcome measures. However, only 26% of the patients with psychotic mood disorders sustained a clinically meaningful mood-stabilizing effect with add-on olanzapine treatment at follow-up.

synthesis and biological testing of nonionic iodinated x-ray contrast media.

A series of nonionic x-ray contrast media containing novel linkages between the triiodobenzene and polyhydroxy moieties have been prepared and screened against established criteria. Of the coupler groups examined (amide including dipeptide, carbamate, ureido, and ester), amide showed the greatest overall utility in terms of safety, solubility, stability, and ease of synthesis. Acute toxicity, solubility and stability data are summarized for each series. In the CNS, certain compounds were well tolerated and some were devoid of any excitatory effects. Intrathecal tissue irritant effects were also unremarkable. Most agents exhibited relatively high osmolalities, raising questions as to the influence of this factor on the safety of myelographic agents. Intravascularly, nonionic media appear also to offer advantages over classical ionic media. However, nonionic media can exert positive inotropic effects and exhibit high viscosity at higher iodine concentrations. Nevertheless, overall results continue to demonstrate the radiographic potential of nonionic contrast media.
