Systematic review with meta-analysis: prevalence, risk factors and costs of aminosalicylate use in Crohn's disease.

BACKGROUND: Aminosalicylates are the most frequently prescribed drugs for patients with Crohn's disease (CD), yet evidence to support their efficacy as induction or maintenance therapy is controversial. AIMS: To quantify aminosalicylate use in CD clinical trials, identify factors associated with use and estimate direct annual treatment costs of therapy. METHODS: MEDLINE, Embase and CENTRAL were searched to April 2017 for placebo-controlled trials in adults with CD treated with corticosteroids, immunosuppressants or biologics. The proportion of patients co-prescribed aminosalicylates in placebo arms was pooled using a random-effects model. Meta-regression was used to identify factors associated with aminosalicylate use. Annual treatment costs were estimated using the 2016 Ontario Drug Benefit Program. RESULTS: Forty-two induction and 10 maintenance trials were included. The pooled proportion of patients co-prescribed aminosalicylates was 44% [95% CI: 39%-49%] in induction trials and 49% [95% CI: 35%-64%] in maintenance trials. There was substantial to considerable heterogeneity (I2  = 86.0%, 91.8% for induction and maintenance trials, respectively). In multivariable meta-regression, aminosalicylate use has decreased over time in induction trials (OR 0.50 [95% CI: 0.34-0.74] per 10-year increment). While a decline has been seen over time, 35% of CD patients were still using aminosalicylates in contemporary trials from the last 5 years. The estimated annual cost for the lowest price mesalazine (mesalamine) formulation is approximately $32 million for the Canadian CD population. CONCLUSIONS: Over one-third of CD patients entering clinical trials are still co-prescribed aminosalicylates. A definitive trial is needed to inform the conventional practice of using aminosalicylates as CD maintenance therapy.

The cost-effectiveness of targeted or universal screening for vasa praevia at 18-20 weeks of gestation in Ontario.

OBJECTIVES: To estimate the cost-effectiveness of targeted and universal screening for vasa praevia at 18-20 weeks of gestation in singleton and twin pregnancies. DESIGN: Cost-utility analysis based on a decision-analytic model comparing relevant strategies and life-long outcomes for mother and infant(s). SETTING: Ontario, Canada. POPULATION: A cohort of pregnant women in 1 year. METHODS: We constructed a decision-analytic model to estimate the lifetime incremental costs and benefits of screening for vasa praevia. Inputs were estimated from the literature. Costs were collected from the London Health Sciences Centre, the Ontario Health Insurance Program, and other sources. We used one-way, scenario and probabilistic sensitivity analysis to determine the robustness of the results. MAIN OUTCOME MEASURES: Incremental costs, life expectancy, quality-adjusted life-years (QALY) and incremental cost-effectiveness ratio (ICER). RESULTS: Universal transvaginal ultrasound screening of twin pregnancies has an ICER of $5488 per QALY-gained. Screening all singleton pregnancies with the risk factors low-lying placentas, in vitro fertilisation (IVF) conception, accessory placental lobes, or velamentous cord insertion has an ICER of $15,764 per QALY-gained even though identifying some of these risk factors requires routine use of colour Doppler during transabdominal examinations. Screening women with a marginal cord insertion costs an additional $27,603 per QALY-gained. Universal transvaginal screening for vasa praevia in singleton pregnancies costs $579,164 per QALY compared with targeted screening. CONCLUSIONS: Compared with current practice, screening all twin pregnancies for vasa praevia with transvaginal ultrasound is cost-effective. Among the alternatives considered, the use of colour Doppler at all transabdominal ultrasound examinations of singleton pregnancies and targeted use of transvaginal ultrasound for IVF pregnancies or when the placenta has been found to be associated with one or more risk factors is cost-effective. Universal screening of singleton pregnancies is not cost-effective compared with targeted screening.

Comparing and predicting the costs and outcomes of patients with major and minor stroke using the Boston Acute Stroke Imaging Scale neuroimaging classification system.

BACKGROUND AND PURPOSE: A neuroimaging-based ischemic stroke classification system that predicts costs and outcomes would be useful for clinical prognostication and hospital resource planning. The Boston Acute Stroke Imaging Scale (BASIS), a neuroimaging-based ischemic stroke classification system, was tested to determine whether it was able to predict the costs and clinical outcomes of patients with stroke at an urban academic medical center. MATERIALS AND METHODS: Patients with ischemic stroke who presented in the emergency department in 2000 (230 patients) and 2005 (250 patients) were classified by using BASIS as having either a major or minor stroke. Compared outcomes included death, length of hospitalization, discharge disposition, use of imaging and intensive care unit (ICU) resources, and total in-hospital cost. Continuous variables were compared by univariate analysis by using the Student t test or the Satterthwaite test adjusted for unequal variances. Categoric variables were tested with the chi(2) test. Multiple regression analyses related total hospital cost (dependent variable) to stroke severity (major versus minor), sex, age, presence of comorbidities, and death during hospitalization. Logistic regression analysis was applied to identify the significant predictive variables indicating a greater likelihood of discharge home. RESULTS: In both years, individuals with strokes classified as major had a significantly longer length of stay, spent more days in the ICU, and had a higher cost of hospitalization than patients with minor strokes (all outcomes, P < .0001). All deaths (8 in 2000, 26 in 2005) occurred in patients with major stroke. Whereas 73% of patients with minor stroke were discharged home, only 12.2% of patients with major stroke were discharged home (P < .0001); 61% of patients with major stroke were discharged to a rehabilitation or skilled nursing facility. Patients with major stroke cost 4.4 times and 3.0 times that of patients with minor stroke in 2000 and 2005, respectively. Making up less than one third of all patients, patients with major stroke accounted for 60% of the total in-hospital cost of acute stroke care. CONCLUSIONS: BASIS, a neuroimaging-based stroke classification system, is highly effective at predicting in-hospital resource use, acute-hospitalization cost, and outcome. Predictive ability was maintained across the years studied.

[Piezosurgery mandibular enostosis: case report]. / Asportazione di enostosi mandibolare mediante tecnica piezoelettrica: case report.

The bone surgery has always used manual and rotary instruments. The biomedical engineering with ultrasound working principle has given a new surgery instruments, which allow a selective cutting action of bone tissue and the protection of soft tissue. Our case shows an uncommon clinical lesion surgically dangerous for the narrow adjoining of important anatomical structures as the lower alveolar artery and the lower alveolar nerve. The clinical result and recovery time go toward a smaller traumatic situation of this methodology of the cutting of bone tissue.

Septate uterus: reproductive outcome after hysteroscopic metroplasty.

OBJECTIVE: To evaluate hysteroscopic metroplasty and its effect on reproductive outcome. STUDY DESIGN: Seventy-five patients consulted for uterine septum between January 1996 to December 2000 at "La Sapienza" University in Rome were included in the study. RESULTS: Forty patients attempted pregnancy and a total of 30 spontaneous pregnancies resulted (75% pregnancy rate). The uterine cavity was normal at hysteroscopic follow-up in 68% of cases. CONCLUSION: Correction of uterine septum improves pregnancy outcome of patients. Broadening the indications for hysteroscopic metroplasty should be encouraged for patients who desire to conceive.

Subantral filling by deantigenated heterologous bone and immediate fixture placement.

AIM: A successful implant therapy depends on sufficient quantity of available bone. Latero-posterior maxillary area often represents a hardly useful zone for routine implant therapy in long time edentulous patients. Standard procedures of maxillary sinus lifting are the goals of implant-prosthetic rehabilitation. Among different grafting materials used in this kind of procedures, the deantigenated heterologous bone reliability has been tested. METHODS: In a clinical case of maxillary bone atrophy (Misch classification, SA3) a deantigenated heterologous bone grafting and immediate fixture placement has been performed; before prosthetic finalization a biopsy in the grafting site has been carried out in order to obtain an histological evaluation of the graft integration. RESULTS: The histological analysis and X-ray at 1 year follow-up show the formation of osteoid tissue integrated with the surrounding bone tissue, reaching bone maturity by calcification. In spite of a longer time for grafting integration, the advantages of a single-time surgery and the reduction of surgical timing are stressed. CONCLUSIONS: X-rays and histological results lead authors to consider the tested heterologous bone as a valid alternative to autologous bone, especially in those patients where it is preferable to avoid a second surgical site in order to take an inlay graft.

[Controlled release vaginal dinoprostone for the induction of labour]. / Induzione del travaglio di parto con dinoprostone vaginale a rilascio controllato.

AIM: To study the efficacy and safety of controlled release dinoprostone (PGE2) for the induction of labour. METHODS: From March 2001 to August 2002, a total of 173 patients hospitalized for postdate pregnancy, maternal hypertension, intrauterine delayed growth, reduction of amniotic fluid, were studied. In 33 of these patients, a hydrogel strip containing 10 mg dinoprostone, inserted into the posterior fornix of the vagina and release PGE2 at constant rate of 0.3-0.4 mg/h was used. RESULTS: Indications for induction, mode and time of delivery, maternal, fetal and neonatal parameters anomalies are evaluated. In 23 patients dinoprostone was used for postdate pregnancy, in 4 for maternal hypertension, in 4 for oligohydramnios and in 2 for intrauterine delayed growth. In 2 cases, the vaginal insert was removed for hyperstimulation in 1 case and for abnormal fetal heart rate in the other case. After vaginal delivery, Apgar scores and umbilical artery pH values were evaluated without anomalies. Vaginal delivery within 24 hours occurred in 51.6% of patients and medium time to delivery was 17.5 (nulliparous) and 12.3 (multiparous) hours. Only one case of uterine hyperstimulation to PGE2 was recorded, and the induction was suspended. The cesarean section rate was 12% and vaginal delivery after 24 hours was 38.7%. CONCLUSION: The continuous release of PGE2 from the vaginal insert permits a controlled and safe induction of labour, minimal risk of hyperstimulation, fast and easy removal of drugs in cases of fetal or maternal anomalies, easy accetability for patients, but high cost.

Successful diagnostic and surgical hysteroscopy for endometrial ossification.

PURPOSE OF INVESTIGATION: Diagnostic-operative hysteroscopy was successful in two cases of endometrial ossification, and fertility was restored. METHODS: A 30-year-old and a 32-year-old woman presented at our Department with a history of secondary infertility, complaining of pelvic pain, dysmenorrhea and polymenorrhea which lasted for about one year before admission. Previous ultrasound studies revealed the presence of two bright hyperechogenic bands with posterior shadowing. RESULTS: In both cases diagnostic-operative hysteroscopies were performed, displaying osseous fragments which were removed with resectoscopy, mainly mechanically. CONCLUSION: Hysteroscopic resection should be the elective treatment for endometrial ossification because it allows complete removal of osseous fragments and reduces the chance of residual synechia. The mean objective of hysteroscopy in endometrial ossification is the restitution of conceivement capability.

Abdominal cystic lymphangioma in a woman at 14 weeks' gestation: case report.

Lymphangiomas are uncommon benign tumors that most commonly present early in life, and are even more exceptional in adults. We present a rare case of a 14-week pregnant woman who had a large septated cystic lesion adherent to the ileum. Despite analysis by ultrasound, the correct diagnosis was established only via laparotomy and she had surgical resection of an abdominal lymphangioma.

HPV and intraepithelial neoplasia recurrent lesions of the lower genital tract: assessment of the immune system.

OBJECTIVE: To evaluate the immune state in patients with genital relapse HPV and intraepithelial lesions of the lower genital tract. METHOD: Forty-three patients were selected. Twenty-one were affected by recurrent HPV infection either alone or combined with intraepithelial neoplasia treated by laser surgery, and 22 had been previously-treated and clinically cured without recurrence during a follow-up from 18 to 24 months. The diagnostic protocol included colposcopy with eso- and endocervical cytology histologically confirmed by directed biopsy. Afterwards patients underwent a systemic immunogenic evaluation. RESULTS: NK cell reduction was strictly related to HPV infection associated with intraepithelial lesions; B-lymphocyte reduction was percentually greater in patients affected by HPV alone; activation of R-IL2 increased in a percentage overlapping in the two groups indicating patient reaction to the virus. CONCLUSION: Our study supports the theory that immune response directed against viral antigens is one of the most important effectors in the control of HPV infections and that HPV is the cause of a systemic rather than local lesion.

Langerhans cell histiocytosis of vulva and cervix in a 19-year-old woman.

Langerhans cell histiocytosis of the female genital tract is a rare disease. A clinical diagnosis is impossible to establish because no typical lesions are found. Immunohistochemistry of bioptic samples is the easier technique to obtain the correct diagnosis. We present a case of a 19-year-old woman with Langerhans cell histiocytosis of mandible and maxilla with subsequent cervical and vulvar histiocytosis.

Cervical intraepithelial neoplasia and bacterial vaginosis: correlation or risk factor?

Bacterial Vaginosis (B.V.) is a syndrome defined microbiologically where lactobacilli-dominated flora is exchanged with an abundant complex flora dominated by strict and facultative anaerobic bacteria, constituted by gardenerella, micrococci, streptococci and staphylocci. It has been suggested that B.V. could be important in the development of cervical intracpithelial neoplasias, because the abnormal micro flora can produce careinogenic nitrosamines. The aim of this investigation was to evaluate the correlation between CIN and B.V. in 1,008 patients (median age: 28 years, range 17-60) who were divided into two groups: the first group consisted of 504 patients affected by CIN of different degrees, the second of 504 patients without CIN. All patients were submitted to colposcopy, pap-tests, cytology of the cervical canal and microcolpohysteroscopy in the case of lesions invading the cervical canal. The diagnosis of B.V. is based on four criteria: presence of clue cells, pH 4.5, positive amine test and increased vaginal discharge. X2 Pearson analysis was applied for statistical evaluation of the data. Among the 504 patients in the first group (women affected by CIN of different degrees), 180/504 (36%) women presented B.V. Among the second group (504 women without CIN), 248/504 (49%) women presented B.V. The results of our study demonstrate that there is no significant correlation between CIN and B.V. In the first group of patients affected by CIN and B.V., B.V. was present in 36% of the cases, while in the second group of patients not affected by CIN. B.V. was present in 49% of the cases (P < 0.00005).

Prevention of thromboembolic complications in women undergoing gynecologic surgery.

Our objective was to identify those patients particularly at risk of deep vein thrombosis (DVT) before they underwent extensive gynecologic surgery and to control if, a correct diagnostic analysis and a right pre-operative prophylaxis of patients with risk of developing DVT, was enough to improve post-operative prognosis. Of 2704 patients undergoing gynaecological surgery, 74 were pre-operatively considered at risk of developing DVT. Seventy percent of the patients received pre- and postoperative heparin, while 28% of the women received only postoperative heparin. Nonetheless, seven women receiving this prophylaxis developed DVT. The final results of our study demonstrate that there is a close correlation between incidence of DVT and the presence of risk factors. This incidence can be reduced by prophylactic measures such as elastic stockings for the lower legs, early post-operatory mobilization, hematocrit and volemy control, ending with pharmacological therapy with heparin.

Hysterectomy in women with cervical pregnancy complicated by life-threatening bleeding: a case report.

A 27-year-old women, gravida 2, para 1 presented with massive vaginal bleeding. After two days of bleeding from the external cervical ostium, intracervical tamponade was performed but the bleeding did not stop. At laparotomy, abdominal hysterectomy with adnexa preservation was done because of malacia tissue and life-threatening hemorrhage. Pathological examination revealed an isthmic pregnancy, gravidic decidua, and chorion villi.

Psychoanalytic perspectives on substance abuse: implications for treatment, program planning and social policy.

Current clinical and socio-political interventions with substance abusers are based on two suppositions regarding the addict: a cognitive ability to discern harm to oneself, and a corresponding capacity to discipline oneself in recognition of the punitive consequences of behavior. A psychoanalytic understanding of the addict's intrapsychic needs provides clarification of these assumptions: offering a psychodynamic explication of why the addict can not "just say no." A comparative analysis of early psychoanalytic thought and contemporary ego psychology elucidates the relationship between hysteria and the addictions, demonstrated in clinical studies with addicted patients. The clinician's use of self is delineated as a treatment tool, mirroring the need for self-exploration on societal and political levels, with implications for treatment, program planning and social policy.

Thermal responses of unclothed men exposed to both cold temperatures and high altitudes.

Six resting men were exposed to three temperatures (15.5, 21, 26.5 degrees C) for 120 min at three altitudes (sea level, 2,500 m, 5,000 m). A 60-min sea-level control at the scheduled temperature preceded the nine altitude episodes. Comparison of the base-line results at any one temperature showed no differences between rectal temperatures (Tre) or mean weighted skin temperatures (Tsk). After 120 min, Tre and Tsk not only depended on ambient temperature but also altitude. The initial rate of fall in Tre increased with altitude and equilibrium occurred earlier. At 15.5 degrees C, Tre was 0.3 degrees C lower at 5,000 m and 0.2 degrees C lower at 2,500 m than at sea level. Tsk was almost 2 degrees C higher at 15.5 degrees C at 5,000 m and 1 degrees C higher at 2,500 m than at sea level. Similar, smaller differences were observed at 21 degrees C. Mean weighted body temperature showed no change with altitude, but, since the gradient between core and shell was reduced, a shift of blood toward the periphery is implied.
