    To evaluate the quality assurance of mammography results at a reference institution for the diagnosis and treatment of breast cancer in southern Brazil, based on the BIRADS (Breast Imaging Reporting and Data System) 5th edition recommendations for auditing purposes. Retrospective cohort and cross-sectional study with 4502 patients (9668 mammographies)) who underwent at least one or both breast mammographies throughout 2013 at a regional public hospital, linked to a federal public university. The results were followed until 31 December 2014, including true positives (TPs), true negatives (TNs), false positives (FPs), false negatives (FNs), positive predictive values (PPVs), negative predictive value (NPV), sensitivity and specificity, with a confidence interval of 95%. The study showed high quality assurance, particularly regarding sensitivity (90.22%) and specificity (92.31%). The overall positive predictive value (PPV) was 65.35%, and the negative predictive value (NPV) was 98.32%. The abnormal interpretation rate (recall rate) was 12.26%. The results are appropriate when compared to the values proposed by the BIRADS 5th edition. Additionally, the study provided self-reflection considering our radiological practice, which is essential for improvements and collaboration regarding breast cancer detection. It may stimulate better radiological practice performance and continuing education, despite possible infrastructure and facility limitations. • Accurate quality performance rates are possible despite financial and governmental limitations. • Low-income institutions should develop standardised teamwork to improve radiological practice. • Regular mammography audits may help to increase the quality of public health systems.

    Full Text Available Background: Primary bone lymphoma (PBL is a rare disease and distinct clinicopathological entity. The optimal treatment strategy is still unclear. Because of rarity of PBL, we report our institute experience in PBL clinicopathological feature and treatment results. Methods: 28 patients diagnosed with PBL were referred to Omid Hospital, cancer research center (CRC, between March 2001 and February 2009. Immunophenotype studies on 16 out of 28 pathological blocks were performed. We analyzed disease free survival (DFS and overall survival (OS rates. Results: 14 patients with PBL were analyzed retrospectively. 17 patients (60.7% were male and 11 (39.3% were female with a median age of 41 years (range: 11-79. Long bones were the most primarily site of involvement (71%. 26 (93% patients had diffuse large B cell lymphoma and 2 (7% had small lymphoblastic lymphoma. One (3% patient received radiation alone, 18 (66% cases received combined modality (chemotherapy + radiotherapy and 8 (30% received only chemotherapy during their treatment period. The median follow up was 18 months (range: 1-82. Mean DFS was 51 months (range: 37-66. Overall survival (OS was 54 months (range: 40-68. OS was significantly better in the chemoradiotherapy group compared with other two groups (64 versus 27 months, respectively, p=0.014. DFS was also significantly better in combined modality arm compared with other two groups (64 versus 21 months, respectively, p=0.003. Conclusions: In spite of small number of patients reported in this study, combined modality treatment (chemotherapy and radiotherapy was shown to be useful as an effective treatment strategy in PBL.

    Births in midwife-led institutions may reduce the frequency of medical interventions and provide cost-effective care, while larger institutions offer medically and technically advanced obstetric care. Unplanned births outside an institution and intrapartum stillbirths have frequently been excluded in previous studies on adverse outcomes by place of birth. The objective of the study was to assess peripartum mortality by place of birth and travel time to obstetric institutions, with the hypothesis that centralization reduces institution availability but improves mortality. This was a national population-based retrospective cohort study of all births in Norway from 1999 to 2009 (n = 648,555) using data from the Medical Birth Registry of Norway and Statistics Norway and including births from 22 gestational weeks or birthweight ≥500 g. Main exposures were travel time to the nearest obstetric institution and place of birth. The main clinical outcome was peripartum mortality, defined as death during birth or within 24 hours. Intrauterine fetal deaths prior to start of labor were excluded from the primary outcome. A total of 1586 peripartum deaths were identified (2.5 per 1000 births). Unplanned birth outside an institution had a 3 times higher mortality (8.4 per 1000) than institutional births (2.4 per 1000), relative risk, 3.5 (95% confidence interval, 2.5-4.9) and contributed 2% (95% confidence interval, 1.2-3.0%) of the peripartum mortality at the population level. The risk of unplanned birth outside an institution increased from 0.5% to 3.3% and 4.5% with travel time 2 hours, respectively. In obstetric institutions the mortality rate at term ranged from 0.7 per 1000 to 0.9 per 1000. Comparable mortality rates in different obstetric institutions indicated well-functioning routines for referral. Unplanned birth outside an institution was associated with increased peripartum mortality and with long travel time to obstetric institutions. Structural determinants have

    The purpose of this study was to investigate the effects of labor epidural analgesia (LEA) on maternal and neonatal outcomes among parturients aged 40 years or older. We retrospectively reviewed medical records of all laboring, singleton and cephalic deliveries at ≥36 weeks' gestation at the Saitama Medical Center from April 2003 to September 2012. Women aged ≥40 years who received LEA (≥40 with LEA group) were compared with women aged ≥40 years who delivered without LEA (≥40 without LEA group) and women <40 years who received LEA (<40 with LEA group). Extracted outcomes included mode of delivery, oxytocin augmentation, duration of labor, amount of estimated blood loss, umbilical artery pH, Apgar scores, and neonatal intensive care unit admission. This study included 4441 women. There were 74 women in the ≥40 with LEA group, 369 in the ≥40 without LEA group, and 601 in the <40 with LEA group. The maternal outcomes of emergency cesarean delivery rate (9.5%, 12.5%, 9.0%), instrumental delivery rate (33.8%, 10.3%, 28.3%), duration of labor (521 min, 321 min, 565 min), and estimated blood loss (524 g, 351 g, 412 g) were reported for the ≥40 with LEA, ≥40 without LEA, and <40 with LEA groups, respectively. Neonatal outcomes were not different between these groups. LEA use was not associated with emergency cesarean delivery in the multivariable analysis. Our study showed that parturients aged ≥40 with LEA can expect similar LEA-associated labor outcomes to younger parturients with LEA. © 2016 Japan Society of Obstetrics and Gynecology.

    Domestic violence is a national health crisis, which affects people of all ages, races, and socioeconomic classes. Traumatic brain injury is common in victims because of the high frequency of head and neck injuries inflicted through abuse. These recurrent injuries can lead to chronic symptoms with high morbidity. We conducted a retrospective chart review of 115 patients with a history of head trauma as a result of domestic violence. All patients were seen in a subspecialty traumatic brain injury clinic, at which time information regarding their histories and self-reported symptoms were recorded. In total, 109 females and 6 males were included in our study, with an age range of 4-68 years. Overall, 88% reported more than one injury and 81% reported a history of loss of consciousness associated with their injuries. Only 21% sought medical help at the time of injury. Whereas 85% had a history of abuse in adulthood, 22% had experienced abuse in both childhood and adulthood, and 60% of the patients abused as children went on to be abused as adults. Headache was the most common chief complaint, but on a self-reported symptom severity scale, behavioral symptoms were the most severe. Psychiatric disease was present in 84% of patients. Traumatic brain injury is a frequent sequela of domestic violence, from which many victims sustain multiple injuries without seeking medical care. Brain injuries are often sustained over many years and lead to lasting physical, behavioral, and cognitive consequences. Better understanding of these injuries will lead to improved care for this population.

    The carboplatin desensitization (CD) protocol presented here allows patients with either a positive skin test or a prior hypersensitivity reaction (HSR) to safely, rapidly and effectively continue with carboplatin infusions. Newly described factors can identify patients at risk for developing adverse events during CD. A retrospective review was performed on patients with gynecologic cancer who underwent CD between 2005 and 2014. The CD protocol uses a four-step dilution process over 3.5h. 129 patients underwent CD and completed a total of 788cycles. The desensitization protocol prevented HSRs in 96% (753 out of 788) of these cycles. Patients achieved an average of 6.1cycles (SD±4.55, range 0-23) with CD. The CD protocol allowed 73% (94 of 129) of the patients to undergo carboplatin infusion without reaction. Patients with moderate to life-threatening HSRs (grade 2 through 4) were 10.5years younger at initial CD than patients with grades 0 or 1 HSRs (52.3 vs. 63, P = 0.0307). One patient death occurred during her thirteenth desensitization cycle. The HSR in this case was complicated by pre-exisiting pulmonary hypertension. This is the largest study of its kind showing a safe, effective and rapid (3.5h) CD protocol. The majority of patients with a history of either carboplatin hypersensitivity reaction or a positive skin test completed the CD protocol without HSRs. Age was identified as a risk factor for HSR severity during CD. Age can be employed along with pre-load dependent cardiac conditions as a way to help risk stratify patients undergoing CD.

    The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years. A collaborative multi-institutional study was conducted in Italy in 10 Radiation Oncology Departments. A consecutive series of 586 women with DCIS histologically confirmed, treated between February 1985 and March 2000, was retrospectively evaluated. Median age at diagnosis was 55 years (range: 29–84); 32 patients were 40 years old or younger. All women underwent conservative surgery followed by whole breast RT. Irradiation was delivered to the entire breast, for a median total dose of 50 Gy; the tumour bed was boosted in 295 cases (50%) at a median dose of 10 Gy. After a median follow-up of 136 months (range: 16–292 months), 59/586 patients (10%) experienced a local recurrence: invasive in 37 cases, intraductal in 20 and not specified in two. Salvage mastectomy was the treatment of choice in 46 recurrent patients; conservative surgery in 10 and it was unknown in three patients. The incidence of local recurrence was significantly higher in women younger than 40 years (31.3%) (p= 0.0009). Five patients developed distant metastases. Furthermore 40 patients developed a contralateral breast cancer and 31 a second primary tumour in a different site. The 10-year actuarial overall survival (OS) was 95.5% and the 10-year actuarial disease-specific survival (DSS) was 99%. Our results are consistent with those reported in the literature. In particular it has been defined the importance of young age (40

    Retrospective studies on oral cancer patient profiles related to risk habits could provide etiologic clues for prevention in specific geographic areas. To study risk habit characteristics of oral cancer patients. A cross sectional retrospective case record study of oral cancer patients who reported during 1991-2000 to Karnataka Cancer Therapy and Research Institute, Hubli, India was conducted. Data on socio-demography, histopathology, site of cancer and risk habit profiles of the patients were recorded in a predesigned Performa by one calibrated examiner with internal validity checks. The 1,472 oral cancer patients constituted 11% of total cancer patients. Mean age of the patients was 55 years, ranging from 12-88, with a male: female ratio of 2:1. 1,110 (75%) oral cancer patients had risk habits, 55% were habituated for >10 years and 25% were habit free. 751(51%) patients had individual and 359(24%) had combined risk habits. Majority 59% were chewers of betel quid alone (17%)/betel quid with tobacco (42%); smokers were (31%) and alcohol users were (14%) of patients. Chewers of gutkha, khaini were more in 40 years. Risk habituates were highest (87%) in patients with cancer of buccal mucosa, commonly affected site attributed to chewing habit in (51%) of patients. The prevalence of oral cancer was higher among elderly males predominantly with risk habits of betel quid/tobacco chewing and smoking for more than 10 years.

    The treatment outcome of 24 patients with pathologically-proven non-germinomatous germ cell tumor was retrospectively investigated to determine the effectiveness of radiotherapy. The patients were divided into three groups as follows: group 1, five patients with mature teratoma with or without germinoma; group 2, six patients with immature teratoma with or without germinoma; group 3, 13 patients with other highly malignant tumors. The overall actuarial survival and relapse-free rates at 5 years were 82% and 59%, respectively, with a median follow-up period of 62 months. The actuarial relapse-free rate at 5 years was 100% for group 1, 63% for group 2 and 44% for group 3. There was no difference in the relapse-free rates between total resection and partial resection. Usage of chemotherapy was adversely related to survival probably due to selection bias. No local failure was observed with 10 Gy or more for group 1, 40 Gy or more for group 2 and 54 Gy or more for group 3. In groups 1 and 2, there was no spinal relapses without craniospinal irradiation. In group 3, three of eight patients who did not receive craniospinal irradiation and none of five patients who received craniospinal irradiation experienced spinal relapse. In conclusion, highly malignant GCTs show a high incidence of spinal metastasis and craniospinal irradiation may reduce the risk of spinal metastasis. Radiation dose and volume are to be determined according to the histopathological aggressiveness. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Full Text Available Background: Carbon monoxide (CO is a colorless, odorless, tasteless, and nonirritating gas which makes it difficult for those who are exposed, to detect it, leading to unexpected death. This study was undertaken to see the pattern of fatal CO poisoning and to discuss preventive aspect. Materials and Methods: It was a retrospective descriptive study of fatal CO cases which were autopsied at All India Institute of Medical Sciences, New Delhi, from the year 2010 to the year 2015. The cases were analyzed as per age groups, circumstances of death, season of death, and sources of CO formation. Results and Discussion: The study involved 40 cases of fatal CO poisoning. About 80% of cases were reported in winter months. The maximum cases were reported in the month of January followed by November and December. All the cases except one, died with a source of CO nearby and the person was inside a room or some closed space without ventilation. Source of CO was firepot and electric room heater in most of the cases. Some cases were of CO build inside the car with a running engine. Most of the cases occurred accidentally. Conclusion: Clustering of cases is seen in winters. Poisoning can occur in different ways. The study documents the various possibilities of CO poisoning and advocates community education targeting the high-risk groups and masses, especially during the winter season.

    The optimal treatment of recurrent glioblastoma (GBM) in elderly patients is unclear. Fotemustine (FTM) is a third-generation nitrosourea showing efficacy in gliomas and it has been used with different schedules in adult patients. We performed, for the first time anywhere, a mono-institutional retrospective study to analyze the clinical outcome of an alternative fotemustine schedule in elderly patients with recurrent GBM. Retrospectively, we analyzed all GBM patients 65 years or older previously treated with the combination of radiation therapy and temozolomide (TMZ), receiving an alternative FTM schedule as second-line treatment at our Oncological Center from October 2011 to October 2014 with an ECOG PS ≤ 2. FTM was administrated at 80 mg/m(2) every 2 weeks for five consecutive administrations (induction phase), and then every 4 weeks at 80 mg/m(2) as maintenance. We enrolled 44 patients, 33 males and 11 females; average age was 70 years. ECOG PS was 0-1 in 80 % of the patients. 38 patients relapsed during temozolomide (TMZ) therapy. MGMT methylation status was analyzed in 34 patients and MGMT was methylated in 53 % of the patients. The median progression free survival (PFS) and overall survival (OS) from FTM treatment was 4.1 months (95 % CI 3.1-5.2) and 7 months (95 % CI 5.2-8.4), respectively. Patients with MGMT methylated status and patients who relapsed after completing TMZ therapy had a longer PFS and OS from the beginning of FTM. Thrombocytopenia was the most frequent grade 3-4 haematological toxicity (9 %). The alternative schedule of FTM may be an active and safe treatment for elderly patients with recurrent glioblastoma, especially patients with methylated MGMT and who relapsed after completing temozolomide therapy.

    Full Text Available Although the adrenal glands are not common sites of metastasis from hepatocellular carcinoma (HCC, this metastasis can be met in patients with advanced HCC in some clinical settings. However, the effectiveness of radiotherapy against such metastases is unclear. Therefore, we performed the present multi-institutional study to investigate tumor response, overall survival (OS, treatment-related toxicity, and prognostic factors after radiotherapy. We retrospectively reviewed 134 patients who completed a planned radiotherapy for their adrenal metastases. Complete response was noted in 6 (4.3%, partial response in 48 (34.0%, and stable disease in 78 patients (55.3%. The median OS was 12.8 months, and the 1-, 2-, and 5-year OS rates were 53.1%, 23.9%, and 9.3%, respectively. Grade 3 anorexia occurred in 2 patients, grade 3 diarrhea in 1, and grade 3 fatigue in 1. Multivariate analyses revealed that the following factors had significant effects on OS: controlled intrahepatic tumor; controlled extrahepatic metastasis; and Child-Pugh class A. Although patients with adrenal metastasis from HCC had poor OS, radiotherapy provided an objective response rate of 38.3% and disease stability of 93.6%, with minimal adverse events. Therefore, radiotherapy for these patients could represent a good treatment modality, especially for patients with controlled intrahepatic tumors, controlled extrahepatic metastasis, and good hepatic function.

    The purpose of this study was to assess the current status of the treatment for oropharyngeal cancer (OPC) in Japan to assist the planning of clinical trials in the future. The data for 523 patients with previously untreated OPC were obtained from 12 institutions from April 2005 to N/larch 2007. Of the 523 patients, 471 patients with squamous cell carcinoma and with curative intent were included in an analysis of the treatment and its results. Of the 471 patients with OPC treated with curative intent, 186 patients (39.5%) were treated with surgery, 118 (25.1%) with radiotherapy (RT) alone and 167 (355%) with CRT. Surgery was indicated for 60.4% of the patients with stage I, 47.8% in stage II, 29.4% in stage III, and 36.44% in stage IV. CRT was indicated for 8.3% in stage II, but the percentage increased with higher stage. The percentage of RT was around 30% among stage I-III, but in stage IV, 21.3% of the patients were indicated for RT. The median follow-up period was 4 years and 5 months. The 2-year and 5-year overall survival rates for the 471 patients were 85% and 69.9%, respectively. The 5-year overall survival rates for patients treated initially with surgery, RT and CRT were 73%, 69.1% and 65.6%, respectively. The 5-year overall survival rates for patients with stage I, II, III, IVA, and IVB were 78.9%. 87.3%, 69.7%, 66.6%, and 47.7%, respectively. Although this study was retrospective, we could understand the tendency of treatment choice according to various factors and treatment results. The information will be useful for planning clinical trials in the future. (author)

    The study aims to ascertain the prevalence of traumatic dental injures of the maxillary permanent incisors at Dental Department, Pakistan Institute of Medical Science Islamabad during the years 2003-2005. Information concerning age, sex, cause, type of tooth number of injured teeth and patterns of tooth injury were recorded retrospectively from 33 patients aged between 8-40 years, comprising 498 traumatized teeth. The dental record of all the patients presenting with dental trauma were examined for collection of data relating to age, sex, cause, number of injured teeth, type of tooth and type of tooth trauma. Type of tooth trauma was recorded according to the Andreason classification. The data was subsequently processed and analyzed using the SPSS statistical software programme. The statistical significance level was set at 5%. Of the 336 patients, 227 were males (67.6%) and 109 were female (32.4%). The gender difference was statistically significant (p<0.0001). The patients had a total of 498 traumatized teeth. A large number of dental trauma occurred in patients aged between 9-11 years. Most injuries involved one tooth in 227 patients (67.6%). However two teeth in 90 patients (26.7%), three teeth in 11 patients (3.2%) and only in 8 patients (2.3%) four teeth were involved. Fractures in enamel only occurred in 74 teeth (14.6%). Uncomplicated crown fractures in 208 teeth (41.9%) were the most commonly encountered dental trauma. 137 teeth (27.6%) suffered complicated crown fractures, 44 teeth (8.9%) uncomplicated crown-root fractures, 19 teeth (3.8%) complicated crown-root fractures and avulsion in 16 teeth (3.2%) only. The main causes were falls in 225 patients (66.9%), collision with objects in 40 patients (11.9%), road traffic accident in 31 patients (9.2%) violence in 31 patients (6.2%), and sports in 19 patients (5.6%). The maxillary central incisor was traumatized in 384 teeth showing a high percentage of 77%. Raising public dental awareness regarding the

    Mast cell tumors (MCT) are common splenic tumors in cats, but there is limited information on treatment outcomes of cats with this disease. This retrospective study evaluated treatment outcomes in 64 cats with splenic MCT. Cats were categorized into the following treatment groups: splenectomy (A, n = 20); splenectomy with chemotherapy (B, n = 20); chemotherapy alone (C, n = 15); or supportive care (D, n = 9). Median tumor specific survival (MTSS) was: 856, 853, 244, 365 days for groups A, B, C, and D, respectively. The MTSS was not significantly different between the 4 groups. However, comparing cats that had splenectomy (A and B) versus those that did not (C and D), the MTSS was 856 and 342 days, respectively (p=0.008). None of the prognostic factors analyzed significantly influenced survival. Splenectomy (+/- chemotherapy) significantly prolongs survival in cats with mast cell tumors. The role of chemotherapy remains unknown. © 2017 John Wiley & Sons Ltd.

    Purpose In daily clinical practice, the indication for adjuvant chemotherapy (CT) is relatively easy to make in patients with early hormone-receptor-positive (HR+) breast cancer with either very poor or very good clinicopathological prognostic variables. However, this decision is much more difficult in patients with intermediate clinicopathological prognostic variables. Here, we evaluate the value of a gene-expression profile identified by the Prosigna gene signature assay in guiding treatment decision-making in patients with these intermediate features. Methods A consecutive cohort of 577 HR + breast cancer patients surgically treated in a single institution between January 2012 and December 2012 was evaluated. From this population, pre- and post-menopausal patients with intermediate prognosis clinicopathological variables were identified and indication of adjuvant CT in these patients was recorded. The gene signature assay was performed retrospectively in this intermediate risk group. Descriptive statistics are presented. Results Among 96 intermediate-risk patients, 64 postmenopausal patients underwent gene signature testing. Subtype distribution was as follows: Luminal A (N = 33; 51.6%), Luminal B (N = 31; 48.4%). Risk of recurrence (ROR) distribution was as follows: ROR-low (n = 16; 25%); ROR-intermediate (N = 26; 40.6%); and ROR-high (N = 22; 34.4%). CT was subsequently administered in 18.7%, 53.8% and 59.0% of the ROR-low, ROR-intermediate and ROR-high groups, respectively. With the use of the gene signature assay, 59.4% of the intermediate cases were re-classified to either ROR-low or ROR-high risk categories. In the ROR-intermediate group, 11/26 patients (42.3%) had Luminal A and 15/26 (57.7%) had Luminal B. Due to follow-up time constraints, no patient outcome results were evaluated. Conclusion The gene signature assay provides clinically useful information and improved treatment decision-making in patients with intermediate risk based on

    Vitiligo is occasionally seen in melanoma patients. Although several studies indicate a correlation between vitiligo occurrence and clinical response in melanoma patients receiving immunotherapy, most studies have included heterogeneous patient and treatment settings. The aim of this study is to investigate the correlation between the occurrence of vitiligo and clinical benefit of nivolumab treatment in advanced melanoma patients. We retrospectively reviewed unresectable stage III or IV melanoma patients treated with nivolumab. Of 35 melanoma patients treated with nivolumab, 25.7% (9/35) developed vitiligo during treatment. The time from the start of nivolumab treatment to occurrence of vitiligo ranged 2-9 months (mean, 5.2). Of nine patients who developed vitiligo, two (22.2%) had a complete response to nivolumab and two (22.2%) had a partial response. The objective response rate was significantly higher in patients with vitiligo than in patients without vitiligo (4/9 [44.4%] vs 2/26 [7.7%]; P = 0.027). The mean time to vitiligo occurrence in patients achieving an objective response was significantly less than that in patients who showed no response (3.1 vs 6.8 months, P = 0.004). Vitiligo occurrence was significantly associated with prolonged progression-free and overall survival (hazard ratio, 0.24 and 0.16; 95% confidence interval, 0.11-0.55 and 0.03-0.79; P = 0.005, and 0.047, respectively). At the 20-week landmark analysis, however, vitiligo was not associated with a statistically significant overall survival benefit (P = 0.28). The occurrence of vitiligo during nivolumab treatment may be correlated with favorable clinical outcome. © 2016 Japanese Dermatological Association.

    The number of South American Camelids (New World Camelids) housed in Germany has increased in the recent years. While these species were formerly kept solely in zoological gardens, ever more private and commercial livestock is being established. Compared to indigenous livestock animals, they bear some distinctive differences, particularly in terms of digestive tract anatomy and physiology. Therefore, it is of considerable interest for veterinarians working with South American Camelids to obtain knowledge about the distinguishing features of these animals and the typical diseases affecting them in Germany. For this purpose, the necropsy reports, including the anamnestic data, and their diagnostic usefulness, from 1995 to 2012 were studied retrospectively. Du- ring this period, a total of 233 New World Camelids were examined (195 alpacas and 38 llamas). Anamnestic data of diagnostic usefulness regarding the cause of disease were only submitted in a limited number of cases, because most of the animals died without specific symptoms. The following were the most frequent pathological findings: enteritis (n = 91), gastritis (n = 76), cachexia (n = 73), pneumonia (n = 30), stomatitis (n = 27), azotaemia (n = 22) and anaemia (n = 9). An endoparasitosis occurred in 107 cases and was considered the predominant cause of enteritis. As with indigenous ruminants, llamas and alpacas primarily suffered from diseases of the digestive and respiratory tracts. Other organ systems were affected to a lesser extent. Even in cases with severe alterations in the affected organs, South American Camelids do not show or show too late diagnostically indicative clinical symptoms. Therefore, a detailed clinical examination of these animals is important.

    Purpose: The Collaborative Ocular Melanoma Study (COMS) established iodine-125 plaque brachytherapy as an accepted standard treatment for medium-size choroidal melanoma. In the COMS, the prescription dose was 85 Gy. This is a retrospective review of our outcomes in patients treated with lower doses than those used in the COMS. Methods and Materials: From 1990 to 2004, 62 patients were treated with iodine-125 plaque brachytherapy for choroidal melanoma. COMS eye plaques were used with dose prescribed to the apex of the tumor. The median and average dose rates at the tumor apex were 63.5 cGy/h and 62.7 cGy/h, respectively. The median and average total doses were 63.0 Gy and 62.5 Gy (range, 56-69 Gy), respectively. The median and mean durations of implant were 100.0 hours and 101.1 hours (range, 71-165 hours). Results: Median follow-up time was 58.2 months. The 5-year outcomes including overall survival, disease-free survival, cause-specific survival, local failure, secondary enucleation rate, and visual acuity (VA) <20/200 were estimated using the Kaplan-Meier method. Overall, there were 7 local failures, 4 distant failures, and 10 secondary enucleations (6 due to local failure and 4 due to treatment complications). Univariate analysis was performed to identify significant prognostic factors associated with disease-free survival (baseline VA in tumor eye, tumor shape), cause-specific survival (diabetic retinopathy), local failure (none found), secondary enucleation rate (diabetic retinopathy, basal tumor dimension) and VA <20/200 (diabetic retinopathy, tumor shape, age, retinal detachment, treatment depth, and history of vision-limiting condition). Conclusions: Our survival and local control outcomes are comparable to those of the COMS. However, VA at 5 years seems to be better. Lower doses of radiation could potentially lead to better visual outcomes.

    The role of adjuvant radiotherapy (RT) for patients with stage III thymoma after complete resection is not definite. Some authors have advocated postoperative RT after complete tumor resection, but some others suggested observation. In this study, we retrospectively evaluated the effect of postoperative RT on survival as well as tumor control in patients with Masaoka stage III thymoma. Between June 1982 and December 2010, 65 patients who underwent complete resection of stage III thymoma entered the study. Fifty-three patients had adjuvant RT after surgery (S + R) and 12 had surgery only (S alone). Of patients who had adjuvant RT, 28 had three-dimensional conformal RT (3D-CRT)/intensity modulated RT (IMRT) and 25 had conventional RT. A median prescribed dose of 56 Gy (range, 28–60 Gy) was given. The median follow-up time was 50 months (range, 5–360 months). Five- and 10-year overall survival (OS) rates were 91.7% and 71.6%, respectively, for S + R and 81.5% and 65.2% for S alone (P = 0.5), respectively. In the subgroup analysis, patients with 3D-CRT/IMRT showed a trend of improved 5-year OS rate compared with conventional RT (100% vs. 86.9%, P =0.12). Compared with S alone, the 5-year OS rate was significantly improved (100% vs. 81.5%, P = 0.049). Relapses occurred in 15 patients (23.1%). There was a trend of lower crude local recurrence rates for S + R (3.8%) compared with S alone (16.7%) (P = 0.09), whereas the crude regional recurrence rates were similar (P = 0.9). No clear dose–response relationship was found according to prescribed doses. Adjuvant 3D-CRT/IMRT showed potential advantages in improving survival and reducing relapse in patients with stage III thymoma after complete resection, whereas adjuvant RT did not significantly improve survival or reduce recurrence for the cohort as a whole. Doses of ≤ 50 Gy may be effective and could be prescribed for adjuvant RT. To confirm the role of adjuvant 3D-CRT/IMRT in patients who undergo a complete

    Murder followed by suicide (M-S) is a rare phenomenon that has been studied in several countries. Previous studies show that offenders of M-S are predominately men who live in an intimate relationship. Amorous jealousy is often the trigger to commit M-S. Shooting is the most common way to kill a partner and/or children. In general, women are likely to become victims. The aim of this study was to identify M-S and detect patterns of M-S in the district of Ghent and the surrounding areas, since no research on this event was conducted in Belgium. Over a period of 75 years, a total of 80 M-S incidents was recorded involving 176 individuals. Eighty-six percent of the offenders were males and 14% were females. Murder-suicides were mostly completed with firearms. The main motive for offenders to execute M-S is amorous jealousy (56%), followed by familial, financial, or social stressors (27%). In addition, three types of M-S were selected (e.g., spousal murder-suicides, filicide-suicides, and familicides-suicides). Our results suggest differences in these types of M-S in which younger couples' intentions were amorous jealousy; as for older couples the prominent motive was mercy killing; most likely women killed their children and only men committed familicides. Finally a study of the evolution during this period was carried out.

    Conclusion: The relatively low outcome found in this series compared to literature can be mainly explained by the higher prevalence of metastatic disease compared to other series, but also by diagnosis and therapeutic delay, more likely because of bad socioeconomic conditions and lack of coordination between different operators. However, our results are nevertheless comparable to maghrebian series. Our department has established many procedures for improving the outcome and further studies are necessary to evaluate their efficiency.

    Growth hormone deficiency (GHD) is the most common endocrine late effect observed in childhood cancer survivors (CCS) previously submitted to cranial irradiation. Radiation therapy can also increase the risk of second neoplasms (SNs). Since in previous studies GH replacement therapy was associated with increased incidence of neoplasia, we explored the association between SNs and GH replacement therapy in a cohort of CCS with GHD. Within the clinical cohort of CCS referred to the Transition Unit for Childhood Cancer Survivors of Turin between November 2001 and December 2012, we considered all patients who developed GHD as a consequence of cancer therapies. GHD was always diagnosed in childhood. To evaluate the quality of data, our cohort was linked to the Childhood Cancer Registry of Piedmont. GHD was diagnosed in 49 out of 310 CCS included in our clinical cohort. At least one SN was diagnosed in 14 patients, meningioma and basal cell carcinoma being the most common SNs. The cumulative incidence of SNs was similar in GH-treated and -untreated patients (8 SNs out of 26 GH-treated and 6 out of 23 GH-untreated patients; p = 0.331). Age, sex and paediatric cancer type had no impact on SNs development. In our CCS, GH replacement therapy does not seem to increase the risk of SNs. Anyway, independently from replacement therapy, in these patients we observed an elevated risk of SNs, possibly related to previous radiation therapy, which suggests the need of a close long-term follow-up.

    The aim of the study was to identify factors significantly associated with the occurrence of unintended treatment interruptions in adjuvant breast cancer radiotherapy. Patients treated with postoperative radiotherapy of the breast or chest wall between March 2014 and August 2016 were evaluated. The radiotherapy regimens and techniques applied were either conventional fractionation (CF; 28 daily fractions of 1.8 Gy or 25 fractions of 2.0 Gy) or hypofractionation (HF; 15 daily fractions of 2.67 Gy) with inverse planned intensity-modulated radiotherapy (IMRT) or three-dimensional planned conformal radiotherapy (3DCRT). Logistic regression analysis was used to identify factors associated with noncompliance. Noncompliance was defined as the missing of at least one scheduled radiotherapy fraction. In all, 19 of 140 (13.6%) patients treated with HF and 39 of 146 (26.7%) treated with CF experienced treatment interruptions. Of 23 factors tested, the fractionation regimen emerged as the only independent significant prognostic factor for noncompliance on multivariate analysis (CF; p = 0.007; odds ratio, 2.3; 95% confidence interval, 1.3-4.2). No statistically significant differences concerning the reasons for treatment interruptions could be detected between patients treated with CF or HF. HF is significantly associated with a better patient compliance with the prescribed radiotherapy schedule compared with CF. The data suggest that this finding is basically related to the shorter overall treatment time of HF. (orig.) [de

    Background: Computed tomography (CT) has become the standard imaging modality for pre-procedural aortic annular sizing prior to transcatheter aortic valve replacement (TAVR). We hypothesized that the accuracy of CT derived annular measurements would be greater at sites with higher TAVR procedural volume. Methods: Within a large integrated health system, TAVR was performed at low (<40 cases), intermediate (40–75 cases), and high-volume sites (>75 cases). 181 patients underwent TAVR with a Sapien XT transcatheter heart valve (THV). Two blinded experienced readers independently remeasured the annulus on CT and compared their measurements to site reported measurements. Hypothetical THV sizes were chosen based on measurements from site CT reports and independent readers’ measurements, and compared to the implanted THV size. Results: Correlation between site reported measurements and independent readers measurements of mean annulus size varied between low-volume (r = 0.31, p = 0.18), intermediate-volume (r = 0.34, p = 0.01), and high-volume sites (r = 0.96, p < 0.01). On multivariate analysis, interpretation of ≥20 CT scans (OR 0.29; 95% CI 0.03–0.81; p 0.02) and high-volume site (OR 0.16; 95% CI 0.10–0.82; p 0.02) were associated with reduced mismatch between the site predicted THV size and independent readers predicted THV size. Mismatch between site predicted THV size and implanted THV size was associated with a worse 30-day composite of mortality, dialysis-dependent renal failure, cerebrovascular accident, new permanent pacemaker, and hospital readmission (55.3 vs. 38.7%; p = 0.05). Conclusions: Accuracy of CT aortic annular sizing is improved with higher individual experience and site TAVR volume. These findings should be confirmed in larger, prospective studies. - Highlights: • Accuracy of CT aortic annular sizing is improved with higher individual experience and site TAVR volume. • CT readers with experience interpreting ≥20 pre-TAVR CT scans had

    Postoperative chemoradiation as per Intergroup-0116 trial ('Macdonald regimen') is considered standard for completely resected high risk gastric cancer. However, many concerns remain with regards to the toxicity of this regimen. To evaluate the safety and tolerability of this regimen in a routine clinical practice setting, we analyzed our experience with its use. As we did not expect a different toxic profile in patients (pts) with positive margins (R1 resection), these were studied together with pts after complete resection (R0). Postoperative chemoradiation therapy was given according to the original Intergroup-0116 regimen. Overall survival (OS) and disease free survival (DFS) rates were calculated using the Kaplan-Meier method. Comparison of OS and DFS between R0 and R1 pts was done using the log-rank test. Between 6/2000 and 12/2007, 166 pts after R0 (129 pts) or R1 (37 pts) resection of locally advanced gastric adenocarcinoma received postoperative chemoradiation; 61% were male and the median age was 63 years (range, 23-86); 78% had T ≥ 3 tumors and 81% had N+ disease; 87% of the pts completed radiotherapy and 54% completed the entire chemoradiation plan; 46.4% had grade ≥ 3 toxicity and 32% were hospitalized at least once for toxicity. Three pts (1.8%) died of toxicity: diarrhea (1), neutropenic sepsis (1) and neutropenic sepsis complicated by small bowel gangrene (1). The most common hematological toxicity was neutropenia, grade ≥ 3 in 30% of pts and complicated by fever in 15%. The most common non-hematological toxicities were nausea, vomiting and diarrhea. With a median follow-up of 51 months (range, 2-100), 62% of the R0 patients remain alive and 61% are free of disease. Median DFS and OS for R0 were not reached. R0 pts had a significantly higher 3-year DFS (60% vs. 29%, p = 0.001) and OS (61% vs. 33%, p = 0.01) compared with R1 pts. In our experience, postoperative chemoradiation as per Intergroup-0116 seems to be substantially toxic

    Identification of patients at risk of hereditary cancer is an essential component of oncology practice, since it enables clinicians to offer early detection and prevention programs. However, the large number of hereditary syndromes makes it difficult to take them all into account in daily practice. Consequently, the National Cancer Institute (NCI) has suggested a series of criteria to guide initial suspicion. It was the aim of this study to assess the perception of the risk of hereditary cancer according to the NCI criteria in our medical oncology service. We retrospectively analyzed the recordings of the family history in new cancer patients seen in our medical oncology service from January to November 2009, only 1 year before the implementation of our multidisciplinary hereditary cancer program. The family history was recorded in only 175/621 (28%) patients. A total of 119 (19%) patients met 1 or more NCI criteria (1 criterion, n = 91; 2 criteria, n = 23; 3 criteria, n = 4; and 4 criteria, n = 1), and only 14 (11.4%) patients were referred to genetic counseling. This study shows that few clinicians record the family history. The perception of the risk of hereditary cancer is low according to the NCI criteria in our medical oncology service. These findings can be explained by the lack of a multidisciplinary hereditary cancer program when the study was performed. Copyright © 2012 S. Karger AG, Basel.

    The purpose of this study was to assess the current status in Japan of the treatment for squamous cell carcinoma of the T4 maxillary sinus (MS-SCC) and its use to plan clinical trials in the future. The data for 128 patients with previously untreated MS-SCC were obtained from 28 institutions from 2006 to 2007. Of the 128 patients, 118 patients with curative intent were included in an analysis of the treatment and its results. Of the 118 patients, 73 patients had T4a disease, and 45 with T4b. Thirty-nine patients (33.1%) were treated with total maxillectomy, 25 (21.2%) with partial maxillectomy, 22 patients (18.6%) with RADPLAT, 19 patients (16.1%) with IV-CRT, and 13 patients (11.0%) with others. The 5-year overall survival rate and local control rate for 118 patients were 49.8% and 48.9%, respectively. The 5-year overall survival rates for patients with T4aN0M0 and T4bN0M0 were 67.5% and 29.8%, respectively. This study was retrospective, but we could understand the tendency of treatment choice and treatment results. It will be useful information to plan clinical trials in the future. (author)

    Outcomes after successful endovascular therapy in acute ischemic stroke are associated with onset-to-reperfusion time (ORT) and the National Institutes of Health Stroke Scale (NIHSS) score. In intravenous recombinant tissue plasminogen activator therapy, the NIHSS-time score, calculated by multiplying onset-to-treatment time with the NIHSS score, has been shown to predict clinical outcomes. In this study, we assessed whether a similar combination of the ORT and the NIHSS score can be applied to predict the outcomes after endovascular therapy. We retrospectively reviewed the charts of 128 consecutive ischemic stroke patients with successful reperfusion after endovascular therapy. We analyzed the association of the ORT, the NIHSS score, and the NIHSS-time score with good outcome (modified Rankin Scale score ≤ 2 at 3 months). Good outcome rates for patients with NIHSS-time scores of 84.7 or lower, scores higher than 84.7 up to 127.5 or lower, and scores higher than 127.5 were 72.1%, 44.2%, and 14.3%, respectively (P < .01). Multivariate logistic regression analysis revealed that the NIHSS-time score was an independent predictor of good outcomes (odds ratio, .372; 95% confidence interval, .175-.789) after adjusting for age, sex, internal carotid artery occlusion, plasma glucose level, ORT, and NIHSS score. The NIHSS-time score can predict good clinical outcomes after endovascular treatment. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    We aimed to evaluate the effect of sarcopenia, a condition of low muscle mass, on the survival among patients who were undergoing radical nephroureterectomy (RNU) for urothelial carcinoma of the upper urinary tract (UCUT). We retrospectively reviewed consecutive patients with UCUT (cT[any]N0M0) who underwent RNU between 2003 and 2013 at our department and its affiliated institutions. Preoperative computed tomography images were used to calculate each patient's skeletal muscle index, an indicator of whole-body muscle mass. Sarcopenia was defined according to the sex-specific consensus definitions, based on the patient's skeletal muscle and body mass indexes. We analyzed the relapse-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) after RNU to identify factors that predicted patient survival. A total of 137 patients were included, and 90 patients (65.7 %) were diagnosed with sarcopenia. Compared to the non-sarcopenic patients, the sarcopenic patients had a significant inferior 5-year RFS (48.8 vs. 79.6 %, p = 0.0002), CSS (57.1 vs. 92.6 %, p sarcopenia was an independent predictor of shorter RFS, CSS, and OS (all, p Sarcopenia was an independent predictor of survival among patients with UCUT who were undergoing RNU.

    Full Text Available Transplant renal artery stenosis (TRAS is the most frequent vascular complication after kidney transplantation (KT and has been associated with potentially reversible refractory hypertension, graft dysfunction, and reduced patient survival. The aim of the study is to describe the outcomes of a standardized Duplex Ultrasound- (DU- based screening protocol for early diagnosis of TRAS and for selection of patients potentially requiring endovascular intervention. We retrospectively reviewed our prospectively collected database of KT from January 1998 to select patients diagnosed with TRAS. The follow-up protocol was based on a risk-adapted, dynamic subdivision of eligible KT patients in different risk categories (RC with different protocol strategies (PS. Of 598 patients included in the study, 52 (9% patients had hemodynamically significant TRAS and underwent percutaneous angioplasty (PTA and stent placement. Technical and clinical success rates were 97% and 90%, respectively. 7 cases of restenosis were recorded at follow-up and treated with re-PTA plus stenting. Both DU imaging and clinical parameters improved after stent placement. Prospective high-quality studies are needed to test the efficacy and safety of our protocol in larger series. Accurate trial design and standardized reporting of patient outcomes will be key to address the current clinical needs.

    We aim to assess the correlation of tumor and nodal staging to survival in pT3N+ and T4aN0 laryngeal cancer with subgroup analysis within stage IVa (pT4N0 and pT3N2). Retrospective cohort study with systematic review of the literature. Hotel Dieu de France University Hospital (tertiary referral center). Laryngeal cancer patients' registries were reviewed from 1998 to 2012 selecting pT3N+ and pT4aN0 patients treated by primary total layngectomy. Overall survivals were compared using Log rank and Kaplan-Meier analysis. A systematic review was performed by 2 reviewers including all the articles reporting the outcome of these categories of patients. Online databases, including PubMed and EMBASE, were used. Reference sections of identified studies were examined for additional articles. Thirteen T3N+ patients and 19 T4aN0 patients treated by primary total laryngectomy were included. Five-year overall survival for T3N+, T3N2 and T4aN0 was respectively 33%, 32.1% and 73.7%. Due to the small sample, the difference was not significant. The systematic review revealed three articles reporting overall survival outcome for the T4N0 group and 6 articles for the T3N+. At 5years, the survival ranged from 62.5% to 73% in T4N0 and from 32.2% to 77% in T3N+. In advanced stage laryngeal cancer, T4aN0 tends toward a better survival than T3N+ especially when compared to T3N2 although they are grouped in the same TNM stage IVa. Copyright © 2015 Elsevier Inc.

    Full Text Available BACKGROUND: The use of cetuximab in combination with platinum (P plus 5-fluorouracil (F has previously been demonstrated to be effective in the treatment of metastatic squamous cell cancer of head and neck (SCCHN. We investigated the efficacy and outcome of this protocol as a first-line treatment for patients with recurrent or metastatic disease. We evaluated overall-survival (OS, progression-free-survival (PFS, overall response rate (ORR and the treatment toxicity profile in a retrospective cohort. PATIENTS AND METHODS: This study enrolled 121 patients with untreated recurrent or metastatic SCCHN. The patients received PF+ cetuximab every 3 weeks for a maximum of 6 cycles. Patients with stable disease who received PF+ cetuximab continued to receive cetuximab until disease progressed or unacceptable toxic effects were experienced, whichever occurred first. RESULTS: The median patient age was 53 (37-78 years. The patient cohort was 86.8% male. The addition of cetuximab to PF in the recurrent or metastatic setting provided an OS of 11 months (Confidential Interval, CI, 95%, 8.684-13.316 and PFS of 8 months (CI 95%, 6.051-9.949. The disease control rate was 48.9%, and the ORR was 23.91%. The most common grade 3 or 4 adverse events in the PF+ cetuximab regimen were febrile neutropenia (5.7%, skin rash (3.8% and mucosistis (3.8%. CONCLUSIONS: The results of this study suggest that cetuximab plus platinum-fluorouracil chemotherapy is a good option for systemic treatment in advanced SSCHN patients. This regimen has a well-tolerated toxicity profile.

    Purpose: To determine the impact of postoperative radiation therapy (POXRT) on outcome in spinal cord gliomas. Patients and Methods: Data from 242 patients were collected retrospectively from six institutions using a standardized data sheet. Pathology specimens, when available, were centrally reviewed. Results: A total of 183 patients were analyzed: 82 received surgery alone as initial treatment, whereas 101 had surgery and POXRT. Demographic, diagnostic, and treatment factors were analyzed for impact on progression-free (PFS) and overall survival (OS). PFS in ependymoma patients was 74%, 60%, and 35% at 5, 10, 15 years, respectively, and was significantly influenced by treatment type, race, age, tumor grade, and type of surgery on univariate analysis, with age being the only significant factor on multivariate analysis (MVA) (p = 0.01). OS of ependymoma patients was 91%, 84%, and 75% at 5, 10, and 15 years, respectively, and was significantly influenced by both complete resection (p = 0.04) and age (p = 0.03) on MVA. In astrocytomas, PFS was 42%, 29%, and 15% at 5, 10, and 15 years, and was significantly influenced by POXRT in low- and intermediate-grade tumors on MVA (p = 0.02). OS at 5, 10, and 15 years was 59%, 53%, and 32%, respectively, and was significantly influenced by grade on MVA (p < 0.01). Conclusion: Postoperative radiation therapy reduced disease progression in low- and moderate-grade astrocytomas. In ependymomas, complete resection significantly influenced OS

    Although carotid artery stenting (CAS) has been gaining popularity as an alternative to carotid endarterectomy (CEA), perioperative stroke rate following contemporary CAS remains significantly higher than stroke rate after CEA. The purpose of this study was to assess perioperative (within 30 days) therapeutic results in patients with carotid stenosis (CS) after introduction of preoperative carotid magnetic resonance imaging plaque evaluation in a single center performing both CEA and CAS. Based on prospectively collected data for patients with CS who were scheduled for carotid revascularization, retrospective analysis was conducted of 295 consecutive patients with CS. An intervention was selected after consideration of periprocedural risks for both CEA and CAS. Concerning risk factors for CAS, results of magnetic resonance imaging plaque evaluation were emphasized with a view toward reducing embolic complications. CAS was performed in 114 patients, and CEA was performed in 181 patients. Comparing baseline characteristics of the 295 patients, age, T1 signal intensity of plaque, symptomatic CS, urgent intervention, and diabetes mellitus differed significantly between CAS and CEA groups. Among patients who underwent CAS, new hyperintense lesions on diffusion-weighted imaging were confirmed in 47 patients. New hyperintense lesions on diffusion-weighted imaging were recognized in 21.4% of patients who underwent CEA (n = 39), significantly less frequent than in patients who underwent CAS. The overall short-term outcome of CEA and CAS is acceptable. Preoperative carotid magnetic resonance imaging evaluation of plaque might contribute to low rates of ischemic complications in CAS.

    Purpose: To retrospectively assess the efficacy, toxicity, and prognostic factors of weekly low-dose docetaxel-based chemoradiotherapy for Stage III/IV oropharyngeal or hypopharyngeal carcinoma. Methods and Materials: Between 2001 and 2005, 72 consecutive patients with locally advanced oropharyngeal or hypopharyngeal carcinoma were treated with concurrent chemoradiotherapy (CCR; radiation at 60 Gy plus weekly docetaxel [10 mg/m 2 ]). Thirty of these patients also received neoadjuvant chemotherapy (NAC; docetaxel, cisplatin, and 5-fluorouracil) before concurrent chemoradiotherapy. Survival was calculated according to the Kaplan-Meier method. The prognostic factors were evaluated by univariate and multivariate analyses. Results: The median follow-up was 33 months, with overall survival, disease-free survival, and locoregional control rates at 3 years of 59%, 45%, and 52%, respectively. Thirty-six patients (50%) experienced more than one Grade 3 to 4 acute toxicity. Grade 3 mucositis occurred in 32 patients (44%), Grade 4 laryngeal edema in 1 (1%). Grade ≥3 severe hematologic toxicity was observed in only 2 patients (3%). Grade 3 dysphagia occurred as a late complication in 2 patients (3%). Multivariate analyses identified age, T stage, hemoglobin level, and completion of weekly docetaxel, but not NAC, as significant factors determining disease-free survival. Conclusions: Docetaxel is an active agent used in both concurrent and sequential chemoradiotherapy regimens. Mucositis was the major acute toxicity, but this was well tolerated in most subjects. Anemia was the most significant prognostic factor determining survival. Further studies are warranted to investigate the optimal protocol for integrating docetaxel into first-line chemoradiotherapy regimens, as well as the potential additive impact of NAC.

    This retrospective study on early and locally advanced esophageal cancer was conducted to evaluate locoregional failure and its impact on survival by comparing involved field radiotherapy (IFRT) with elective nodal irradiation (ENI) in combination with concurrent chemotherapy. We assessed all patients with esophageal cancer of stages I-IV treated with definitive radiotherapy from June 2000 to March 2014. Between 2000 and 2011, ENI was used for all cases excluding high age cases. After Feb 2011, a prospective study about IFRT was started, and therefore IFRT was used since then for all cases. Concurrent chemotherapy regimen was nedaplatin (80 mg/m 2 at D1 and D29) and 5-fluorouracil (800 mg/m 2 at D1-4 and D29-32). Of the 239 consecutive patients assessed (120 ENI vs. 119 IFRT), 59 patients (24.7 %) had stage IV disease and all patients received at least one cycle of chemotherapy. The median follow-up time for survivors was 34.0 months. There were differences in 3-year local control (44.8 % vs. 55.5 %, p = 0.039), distant control (53.8 % vs. 69.9 %, p = 0.021) and overall survival (34.8 % vs. 51.6 %, p = 0.087) rates between ENI vs. IFRT, respectively. Patients treated with IFRT (8 %) demonstrated a significantly lower risk (p = 0.047) of high grade late toxicities than with ENI (16 %). IFRT did not increase the risk of initially uninvolved or isolated nodal failures (27.5 % in ENI and 13.4 % in IFRT). Nodal failure rates in clinically uninvolved nodal stations were not increased with IFRT when compared to ENI. IFRT also resulted in significantly decreased esophageal toxicity, suggesting that IFRT may allow for integration of concurrent systemic chemotherapy in a greater proportion of patients. Both tendencies of improved loco-regional progression-free survival and a significant increased overall survival rate favored the IFRT arm over the ENI arm in this study

    Adult medulloblastoma is a rare disease treated according to the current pediatric treatment guidelines. This retrospective analysis investigated the clinical outcomes and prognostic factors of adult medulloblastoma patients, who received multimodal therapy at our institution. Treatment charts of all patients over the age of 15 years of age with de novo medulloblastoma, who had been treated at our institution between 2001 and 2014, were retrospectively analyzed. Patients' demographic parameters, initial symptoms, treatment modalities, toxicities, and survival outcomes were investigated. In all, 21 patients with a median age of 30.2 years were identified. The most frequent histologies were desmoplastic and classic, and the most common molecular subtype was sonic hedgehog (SHH). After tumor resection, all patients received craniospinal irradiation (median dose 35.2 Gy) and a boost to the posterior fossa (median dose 19.8 Gy). Simultaneous chemotherapy with vincristine was given to 20 patients and sequential chemotherapy to 15 patients. The most common side effects were hematological toxicities. Median overall survival (OS) has not been reached after a median follow-up of 92 months. Estimated 5- and 10-year OS was 89 and 80%, respectively. Estimated 5- and 10-year progression-free survival (PFS) was 89 and 81%, respectively. In univariate analysis, a shorter interval between tumor resection and end of irradiation was significantly associated with improved OS and PFS, anaplastic histology with worse OS and PFS. The combined modality treatment showed a good outcome in adults with medulloblastoma. Treatment time was revealed to be prognostic and should be kept as short as possible. (orig.)

    The prognosis of locally advanced cervix cancers is poor with metastatic and local recurrence risks. Recent publications reported that concurrent chemotherapy and pelvic radiation increased local control compared to radiotherapy alone. Chemotherapy could also decrease metastatic recurrences. We report 92 cases of patients with locally advanced cervix cancer treated between 1986 and 1998 at the Institut Curie. Patients and methods. - Concurrent chemo-radiation was exclusive in 51 cases and added to surgery in 41 cases. Chemotherapy with 5FU -Cisplatin-Mitomycin C-Vindesin (protocol A) was performed for 43% of patients and 57% of them received 5FU-Cisplatin alone (protocol B). Results. -Median follow-up was 64 months (6-149 months). Five-year disease-free survival rate was 47% and local control rate was 70%. Disease-free survival was correlated with therapeutic response. After exclusive chemo-radiation, the good responsive patients had a better DFS (54% vs 26%, p=0.018). In the surgery group, those patients with sterilized lymph nodes and tumours had also a higher DFS (76% vs 47%, p=0.036). Toxicity was higher with protocol A. Conclusion. - From our study, it appears that local control of advanced cervix cancers is better with combined chemoradiotherapy but disease-free survival stays low according to the metastatic evolution. Metastasis without local recurrence remained frequent in our study. 5FU-CDDP chemotherapy has a lower toxicity and is as effective as 5FU-CDDP-Mitomycin C-Vindesin protocol, in association with radiotherapy.

    Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

    Hospitals have been slow to adopt guidelines from the American Heart Association (AHA) limiting the use of continuous cardiac monitoring for fear of missing important patient cardiac events. A new continuous cardiac monitoring policy was implemented at a tertiary-care hospital seeking to monitor only those patients who were clinically indicated and decrease the number of false alarms in order to improve overall alarm response. Leadership support was secured, a cross-functional alarm management task force was created, and a system-wide policy was developed based on current AHA guidelines. Process measures, including cardiac monitoring rate, monitored transport rate, emergency department (ED) boarding rate and the percentage of false, unnecessary and true alarms, were measured to determine the policy's impact on patient care. Outcome measures, including length of stay and mortality rate, were measured to determine the impact on patient outcomes. Cardiac monitoring rate decreased 53.2% (0.535 to 0.251 per patient day, pimprovements in process measures coupled with no adverse effects to patient outcomes suggest that the overall system became more resilient to current and emerging demands. This study indicates that when collaboration across a diverse team is coupled with strong leadership support, policies and procedures such as this one can improve clinical practice and patient care.

    To assess the relationship between the timing of radiotherapy and the risk of local failure in patients with endometrioid-type endometrial cancer who had undergone surgery and adjuvant external pelvic radiotherapy (with or without brachytherapy), but not chemotherapy. One hundred and seventy seven patients were analyzed in this study. The median follow-up of the survivors was 72 months. Radiotherapy was delivered after a median time of 14.6 weeks from surgery and the median overall treatment time was 6.4 weeks. The tumor relapsed in 32 (18.1%) patients after a median time of 21 months. The local recurrence (vaginal or central pelvic) occurred in 11 patients. The local recurrence rate was associated with tumor grade (p=0.02), myometrial invasion (p=0.046), FIGO stage (p=0.003), pathological node status (p=0.037) and time interval from surgery to radiotherapy using 9 weeks as the cut-off value (p=0.046), but not with the overall treatment time. All the local relapses occurred in patients who received adjuvant irradiation after an interval from surgery >9 weeks. The time interval from surgery to radiotherapy might affect the local recurrence rate in patients not receiving chemotherapy. Every possible effort should be made to start radiotherapy within 9 weeks, when radiotherapy only is deemed necessary as adjuvant treatment.

    To study the incidence of mandibular third molar impaction in relation to type and side of impaction, age and sex of patients and indications for its surgical removal through data collected from a single institute over a period of 3 and half years. The records of 1198 patients who underwent the surgical removal of impacted mandibular third molars were reviewed retrospectively. Records were divided into groups according to sex, age, type and side of impaction. Radiographs were studied to determine angular position of impacted mandible third molar. We found that there was a high incidence of mesioangular lower third molar impaction (33.97 %), highest number of patients were found in 15-30 years of age group (48.33 %), a left side (56.93 %) was more commonly involved, female predominance (63.44 %) was observed and recurrent pericoronitis (33.81 %) was the most common indication. Awareness of the indications for surgical removal of impacted mandibular third molar to the patients will help to avoid future risk of complications and morbidity associated with the same. This will not only help in saving time and money but also prevents the psychological trauma associated with delayed treatment. Removal of only symptomatic IMTM seems to be the logical choice in view of financial constraint in developing countries like India but at the same time early removal offers freedom from future complications in selected cases. So surgeons should apply a meticulous approach in selecting the patients for SRIMTM.

    Full Text Available BACKGROUND Oesophageal cancer is a serious malignancy with regards to mortality and prognosis. It is a growing health concern that is expected to increase in incidence over the next 10 years. Squamous cell carcinoma is the most common histological type of oesophageal cancer worldwide with a higher incidence in developing nations. With the increased prevalence of gastroesophageal reflux disease and obesity in developed nations, the incidence of oesophageal adenocarcinoma has dramatically increased in the past 40 years. MATERIALS AND METHODS Retrospective study was conducted to study the clinical profile of patients presented with oesophageal carcinoma at Government Medical College, Kottayam, Kerala, India, during January 1, 2015, to December 31, 2016. 104 subjects who met the inclusion criteria were enrolled. Data were collected from the records. RESULTS Out of 104 subjects enrolled in the study, 78 (75% were males, rest 26 (25% were females. 73% of the patients with oesophageal carcinoma were above 60 years. 79.8% patients presented with dysphagia. 87.5% cases had squamous cell type lesions. More than 75% of the lesions were in the mid and lower oesophagus. Noduloulcerative type was the most common morphologic presentation. CONCLUSION Squamous cell carcinoma is the most common oesophageal carcinoma in our institution. Majority of the lesions are located in the mid and lower oesophagus and are well differentiated.

    The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

    The primary aim was to evaluate institutional anesthetic techniques utilized for postpartum tubal ligation (PPTL). Secondarily, academic institutions were surveyed on their clinical practice for PPTL. An institutional-specific retrospective review of patients with ICD-9 procedure codes for PPTL over a 2-year period was conducted. Obstetric anesthesia fellowship directors were surveyed on anesthetic management of PPTL. Labor and delivery unit. Internet survey. 202 PPTL procedures were reviewed. 47 institutions were surveyed; 26 responses were received. Timing of PPTL, anesthetic management, postoperative pain and length of stay. There was an epidural catheter reactivation failure rate of 26% (18/69 epidural catheter reactivation attempts). Time from epidural catheter insertion to PPTL was a significant factor associated with failure: median [IQR; range] time for successful versus failed epidural catheter reactivation was 17h [10-25; 3-55] and 28h [14-33; 5-42], respectively (P=0.028). Epidural catheter reactivation failure led to significantly longer times to provide surgical anesthesia than successful epidural catheter reactivation or primary spinal technique: median [IQR] 41min [33-54] versus 15min [12-21] and 19min [15-24], respectively (P8h and >24h post-delivery, respectively. Epidural catheter reactivation failure increases with longer intervals between catheter placement and PPTL. Failed epidural catheter reactivation increases anesthetic and operating room times. Our results and the significant variability in practice from our survey suggest recommendations on the timing and anesthetic management are needed to reduce unfulfilled PPTL procedures.

    The aim of this study was to evaluate the incidence of a variety of infectious complications in patients with CLL regarding the duration of CLL and the type of treatment. We present the retrospective analysis of patients with CLL treated at our institution in years 2004-2016. We collected data about the type of infection, pathogenes, treatment and severity of infections surpassed in connection with administration treatment. In the study one hundred and ten patients were evaluated. The average age of patients was 61.7 years (range 34.5-91.9 years). Fludarabine was the most widely used regimen, followed by bendamustine and alemtuzumab. We recorded 393 episodes of infections, of which 114 (29%) were severe and life threatening of degree 3-5, and 279 (71%) of degree 2. The most common infections were the upper respiratory tract infections together with sinusitis (45.03%), pneumonia (26.20%), CMV reactivation occured in 8.14%, infections of the skin was in 7.6 %. Most infections have occurred with the administration of monoclonal antibody alemtuzumab, these patients were at significantly higher risk of infection [RR 2.59 (1.30 to 5.17)] than patients receiving obinutuzumab [RR 0.63 (0.48 to 0.82)] (p = 0.0001). On the contrary, the safety profile of BCR signaling pathway inhibitors was very acceptable [RR 1.17 (0.70 - 1.96)]. The number of infections have decreased during the first 12 months of treatment with ibrutinib. In the study group we recorded 19 deaths, 8 (7.27%) of them were of infectious etiology. The risk of infectious complications is lifelong in patients with CLL, it can be minimized by early detection and aggressive management. Novel targeted agents used in therapy of CLL have a good safety profile, even the risk of infection is decreased during administration.

    In this study, we reviewed our institution's experience using component separation for repair of ventral hernias. This was a retrospective review of all component separations for ventral hernia between July 2009 and December 2015. Recorded data included body mass index (BMI), preoperative albumin, smoking history, comorbidities, additional procedures, length of surgery, hospitalization, recurrence, and postoperative complications. One hundred ninety-six component separations were performed in the study period. The average patient age was 56 years, and 65.3% of patients were female. The average BMI was 32.6 kg/m; preoperative albumin was 3.59; 18.4% were current smokers; 28.1% were diabetic; and 14.3% had heart disease. Postoperative complications developed in 16.8% of patients. Recurrence developed in 8.7% of patients. Patients who developed a postoperative complication had a higher BMI (P = 0.025) and lower albumin (P = 0.047) compared with patients who did not develop complications. Current smokers were more likely to develop complications (P = 0.008). More than one third of patients had additional procedures at the time of the ventral hernia repair. The addition of a plastic surgery procedure was not associated with an increased risk of developing a complication (P = 0.25). Patients who developed complications had a significantly longer hospital course (P < 0.001) but no difference in total operative time (P = 0.975). Increased number of comorbidities did not statistically correlate with an increased complication rate (P = 0.65) or length of hospital stay (P = 0.43). We identified risk factors that increase the likelihood of postoperative complications and length of hospital stay. In addition, this study suggests that more comorbidities and additional procedures at the time of the hernia repair may not have as large of impact on complication risk as previously thought.

    Full Text Available When Ken Thomas kindly invited me to contribute to this issue of Archaeology International, my first thought was what a pleasure it would be just to write an article rather than edit the whole issue. Having retired from the job only last year, I well knew the magnitude of the task facing the new editor: one that is challenging and onerous but also intellectually rewarding. So I welcomed the opportunity to add my mite to the sequence of retrospective articles that have been a feature of AI since it was launched nine years ago. But, unlike the former students and staff who have recalled in previous issues the early years in St John's Lodge in Regent's Park, my association with the Institute is much more recent. So rather than write only about the 1980s and 1990s, I have (with Ken's encouragement taken a longer retrospective view, recalling how I followed a path from geography into archaeology, which led eventually to my joining the staff of the Institute in January 1980.

    Usage of data from electronic health records (EHRs) in clinical research is increasing, but there is little empirical knowledge of the data needed to support multiple types of research these sources support. This study seeks to characterize the types and patterns of data usage from EHRs for clinical research. We analyzed the data requirements of over 100 retrospective studies by mapping the selection criteria and study variables to data elements of two standard data dictionaries, one from the healthcare domain and the other from the clinical research domain. We also contacted study authors to validate our results. The majority of variables mapped to one or to both of the two dictionaries. Studies used an average of 4.46 (range 1-12) data element types in the selection criteria and 6.44 (range 1-15) in the study variables. The most frequently used items (e.g., procedure, condition, medication) are often available in coded form in EHRs. Study criteria were frequently complex, with 49 of 104 studies involving relationships between data elements and 22 of the studies using aggregate operations for data variables. Author responses supported these findings. The high proportion of mapped data elements demonstrates the significant potential for clinical data warehousing to facilitate clinical research. Unmapped data elements illustrate the difficulty in developing a complete data dictionary. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  4. Alveolar ridge keratosis - a retrospective clinicopathological study

    Science.gov (United States)

    2013-01-01

    Background Alveolar ridge keratosis (ARK) is a distinct, benign clinicopathological entity, characterized by a hyperkeratotic plaque or patch that occurs on the alveolar edentulous ridge or on the retromolar trigone, considered to be caused by chronic frictional trauma. The aim of this retrospective study is to present the clinicopathological features of 23 consecutive cases of ARK. Material and methods The 23 biopsy samples of ARK were selected and pathological features were revised (keratosis, acanthosis, surface architecture, and inflammation). Factors such as the patient’s gender, age, anatomical location, tobacco and alcohol use were analyzed. Results Sixteen out of the 23 cases studied were men and 7 women with a mean age of 55.05 (age ranged from 17 to 88 years). Thirteen cases had a history of tobacco habit, amongst whom, 4 also presented alcohol consumption. All the cases presented only unilateral lesions. Nineteen cases involved the retromolar trigone while 4 cases involved edentulous alveolar ridges. When observed microscopically, the lesions were mainly characterized by moderate to important hyperorthokeratosis. Inflammation was scanty or absent. In four of the cases, the presence of melanin pigment in the superficial corium or in the cytoplasm of macrophages was detected. None of the cases showed any features of dysplasia. Conclusion Our results reveal that ARK is a benign lesion. However, the high prevalence of smokers amongst the patients might suggest that some potentially malignant disorders such as tobacco associated leukoplakia may clinically mimic ARK. PMID:23587097

    2015-07-01

    Blastocystis is a common single-celled intestinal parasitic genus, comprising several subtypes. Here, we screened data obtained by metagenomic analysis of faecal DNA for Blastocystis by searching for subtype-specific genes in coabundance gene groups, which are groups of genes that covary across a selection of 316 human faecal samples, hence representing genes originating from a single subtype. The 316 faecal samples were from 236 healthy individuals, 13 patients with Crohn's disease (CD) and 67 patients with ulcerative colitis (UC). The prevalence of Blastocystis was 20.3% in the healthy individuals and 14.9% in patients with UC. Meanwhile, Blastocystis was absent in patients with CD. Individuals with intestinal microbiota dominated by Bacteroides were much less prone to having Blastocystis-positive stool (Matthew's correlation coefficient = -0.25, P < 0.0001) than individuals with Ruminococcus- and Prevotella-driven enterotypes. This is the first study to investigate the relationship between Blastocystis and communities of gut bacteria using a metagenomics approach. The study serves as an example of how it is possible to retrospectively investigate microbial eukaryotic communities in the gut using metagenomic datasets targeting the bacterial component of the intestinal microbiome and the interplay between these microbial communities. © FEMS 2015.

    The objective of this study was to compare rates of early morbidity after radical cystectomy in patients treated with or without induction chemoradiotherapy (CRT) using a standardized reporting methodology. All 193 consecutive patients undergoing radical cystectomy for bladder cancer between 1989 and 2010 were retrospectively reviewed. Induction chemoradiotherapy consists of radiation at 40 Gy to the small pelvis and two cycles of concurrent cisplatin at 20 mg/day for 5 days. Deaths within 90 days after radical cystectomy and complications arising within 30 days were recorded and graded according to the Clavien-Dindo classification. Grades 1-2 were considered minor; Grades 3-5 were considered major. Eighty-seven patients underwent radical cystectomy following chemoradiotherapy (chemoradiotherapy group) while the remaining 106 primarily underwent radical cystectomy (no chemoradiotherapy group). No Grade 4-5 complication was observed. Overall, 118 patients (61%) experienced 36 major and 122 minor complications. There was no significant difference in the incidence of overall complications between the chemoradiotherapy and no chemoradiotherapy groups (67 vs. 57%). Overall urinary anastomosis-related complications and major gastrointestinal complications, most of which were Grade 3 ileus, were more frequent in the chemoradiotherapy group than the no chemoradiotherapy group (11 vs. 2%, P=0.007; and 14 vs. 4%, P=0.02; respectively). Multivariate analysis identified induction chemoradiotherapy as an independent risk factor for overall urinary anastomosis-related complications (relative risk 6.0, P=0.01) but not for major gastrointestinal complications. Induction chemoradiotherapy at 40 Gy in bladder-sparing protocols against MIBC is unlikely to increase the rate of severe complications of radical cystectomy. (author)

    To describe the use of hydrotherapy for pain management in labor. This was a retrospective cohort study. Hospital labor and delivery unit in the Northwestern United States, 2006 through 2013. Women in a nurse-midwifery-managed practice who were eligible to use hydrotherapy during labor. Descriptive statistics were used to report the proportion of participants who initiated and discontinued hydrotherapy and duration of hydrotherapy use. Logistic regression was used to provide adjusted odds ratios for characteristics associated with hydrotherapy use. Of the 327 participants included, 268 (82%) initiated hydrotherapy. Of those, 80 (29.9%) were removed from the water because they met medical exclusion criteria, and 24 (9%) progressed to pharmacologic pain management. The mean duration of tub use was 156.3 minutes (standard deviation = 122.7). Induction of labor was associated with declining the offer of hydrotherapy, and nulliparity was associated with medical removal from hydrotherapy. In a hospital that promoted hydrotherapy for pain management in labor, most women who were eligible initiated hydrotherapy. Hospital staff can estimate demand for hydrotherapy by being aware that hydrotherapy use is associated with nulliparity.

    This Objective of this study was to see histologic typing of prostate cancer and its relation to patient's age, as no curative therapy exists for the advanced stages. This is a retrospective study of 50 patients suffering from prostatic adenocarcinoma and admitted at Basic Medical Sciences Institute, Jinnah Postgraduate Medical Center Karachi. A total of fifty patients between ages of 50-80 years diagnosed during the period of 1990-2001 suffering from prostate cancer were included in this study. The result showed that maximum number of tumours were in age group ranging from 61-70 years, (58% of total cases). Sixteen were (32%) well-differentiated tumours, twenty-eight (56%), moderately differentiated tumours and six (12%) were labelled as undifferentiated tumours. It was concluded that the majority of tumors were moderately differentiated tumours. Early diagnosis is useful for patients; because high grade tumours have bad prognostic markers. (author)

    The prevalence of brain metastases (BM) from uterine cancer has recently increased because of the improvement of overall survival (OS) of patients with uterine cancer due to its early detection and improved local control as a result of new effective treatments. However, little information is available regarding their clinical characteristics and prognosis, because oncologists have encountered BM from uterine cancer on rare occasions. Records from 81 patients with uterine BM were collected from 10 institutes in Japan. These were used in a multi-institutional study to identify prognostic factors and develop a graded prognostic assessment (GPA) for patients with BM from uterine cancer. Median OS after the development of BM was 7 months (95% confidence interval, 4 to 10 months). Multivariate analysis revealed that there were survival differences according to the existence of extracranial metastases and number of BM. In the present uterine-GPA, a score of 0 was assigned to those patients with ≥5 BM and extracranial metastasis, a score of 2 was assigned to those patients with one to four BM or without extracranial metastasis, and a score of 4 was assigned to those patients with one to four BM and without extracranial metastasis. The median OS for patients with a uterine-GPA scores of 0, 2, and 4 was 3, 7, and 22 months, respectively. A survival analysis confirmed the presence of statistically significant differences between these groups (p Brain Tumor Registry of Japan. Uterine GPA incorporates two simple clinical parameters of high prognostic significance and can be used to predict the expected survival times in patients with BM from uterine cancer. Its use may help in determining an appropriate treatment for individual patients with BM.

    Full Text Available Context: A variety of nonvenereal diseases can affect the penis and diminish quality of life. Many present similar clinical features and a cutaneous biopsy may be necessary to clarify the diagnosis. Aims: To characterize nonvenereal penile dermatoses with histological confirmation in a southwestern Europe hospital during a 9-year period. Materials and Methods: A retrospective study was conducted. We reviewed all penile biopsies performed between January 1, 2007 and December 31, 2015 and studied the causes of the nonvenereal penile dermatoses. Results: The sample included a total of 108 patients, aged 62.9 (±17.8 years, between 16 years and 96 years of age. Eighteen dermatoses were identified. Inflammatory diseases were present in 65. 7% of patients (71/108 and neoplastic dermatoses in 34. 3% (37/108. Concerning inflammatory dermatoses, the most frequent were Zoon balanitis (27.8%, 30/108, followed by lichen sclerosus (15.7%, 17/108, psoriasis (11.1%, 12/108, and lichen planus (4.6%, 5/108. In patients with psoriasis, 10 had lesions only in the penis, similarly to all patients with lichen planus. The most frequent malignant tumor was squamous cell carcinoma (SCC (15.7%, 17/108. The most common in-situ tumor was erythroplasia of Queyrat (8.3%, 9/108. A case of basal cell carcinoma (BCC was found. Kaposi sarcoma and mycosis fungoides on penis were also diagnosed, as an additional form of presentation to their generalized disease. Conclusions: In this study, inflammatory diseases were the most frequently diagnosed dermatoses, while SCC was the most common malignant tumor found. In the majority of psoriasis and lichen planus cases, clinical lesions were only present in the genital area.

    Full Text Available Purpose: To determine external, middle, and inner ear abnormalities on high-resolution computed tomography (HRCT of temporal bone in patients with microtia and to predict anatomic external and middle ear anomalies as well as the degree of functional hearing impairment based on clinical grades of microtia. Materials and Methods: It was a retrospective study conducted on Indian population. Fifty-two patients with microtia were evaluated for external, middle, and inner ear anomalies on HRCT of temporal bone. Clinical grading of microtia was done based on criteria proposed by Weerda et al. in 37 patients and degree of hearing loss was assessed using pure tone audiometry or brainstem-evoked response in 32 patients. Independent statistical correlations of clinical grades of micotia with both external and middle ear anomalies detected on HRCT and the degree of hearing loss were finally obtained. Results: The external, middle, and inner ear anomalies were present in 93.1%, 74.5%, and 2.7% patients, respectively. Combined cartilaginous and bony external auditory canal atresia (EAC was the most common anatomic abnormality in our group of microtia patients. Hypoplastic mesotympanum represented the commonest middle ear anomaly. The incidence of combined ossicular dysplasia and facial canal anomalies was lower as compared to other population groups; however, we recorded a greater incidence of cholesteatoma. Both these factors can have a substantial impact on outcome of patients planned for surgery. We found no significant association between grades of microtia and external or middle ear anomalies. Similarly, no significant association was found between lower grades of microtia (grade I and II and degree of hearing loss. However, association between grade III microtia and degree of hearing loss was significant. A significant association between congenital cholesteatoma and degree of pneumatization of atretic plate and mastoid process not previously studied

The external, middle, and inner ear anomalies were present in 93.1%, 74.5%, and 2.7% patients, respectively. Combined cartilaginous and bony external auditory canal atresia (EAC) was the most common anatomic abnormality in our group of microtia patients. Hypoplastic mesotympanum represented the commonest middle ear anomaly. The incidence of combined ossicular dysplasia and facial canal anomalies was lower as compared to other population groups; however, we recorded a greater incidence of cholesteatoma. Both these factors can have a substantial impact on outcome of patients planned for surgery. We found no significant association between grades of microtia and external or middle ear anomalies. Similarly, no significant association was found between lower grades of microtia (grade I and II) and degree of hearing loss. However, association between grade III microtia and degree of hearing loss was significant. A significant association between congenital cholesteatoma and degree of pneumatization of atretic plate and mastoid process not previously studied was also recorded in our study

    Glioblastoma Multiforme (WHO grade IV glioma) still remains a dreadful diagnosis in oncology with the median survival ranging between 12 to 17 months, despite the recent advances in its management. It is the most common malignant primary tumour in adults(13). The standard of care is Maximal Safe Resection followed by Concomitant ChemoRadiotherapy. During the period 2006 to 2010 at Radium Institute, Patna Medical College and Hospital (PMCH) in India, a study was conducted on 37 newly diagnosed GBM cases in which the control-arm (c-arm) received Conventional Radiotherapy (60Gy/30#) only whereas the study arm (s-arm) received Concomitant Chemoradiotherapy followed by Adjuvant Temozolomide. The median survival was 15.4 months in the s-arm as compared to 12.4 months in the c-arm. The OS showed a significant improvement with p-value of 0.05 and PFS also showed a benefit with a p-value of 0.005. The results were encouraging with improvement in OS as well as PFS in the s-arm and were at par with the other similar studies conducted in different parts of the world.

    The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and the conducted treatment were analyzed. Odontogenic infections were defined as pulpitis, apical and marginal periodontitis, abscesses and pericoronitis. A total of 2,058 out of 4,209 emergency patients suffered from odontogenic infections. The majority (45.0%) had an apical periodontitis, 20.8% abscesses, 17.3% a marginal periodontitis, 16.3% a pulpitis and 5.8% a pericoronitis. Mean age was 37.5 ± 17.0 years standard deviation (SD) (1.2-96.4). Most patients were 20 to 29 years (24.6%), followed by the age group of 30 to 39 year old patients (21.0%). Males were affected more frequently (55.5%) than females (45.5%). Most of the patients (64.5%) of the patients received a dental or surgical treatment. Antibiotics were prescribed in 31.7% of cases. Amoxicillin was the most common prescribed antibiotic (54.5%). Odontogenic infections represent one of the main reasons for consulting the emergency service. Due to the high number of cases and the severe complications, dentists have to be familiar with the surgical management of odontogenic infections as well as the appropriate use of antibiotics. Nearly half of all patients who sought, treatment in the emergency service had an odontogenic infectious disease. This should be considered for the organization and planning of the service.

    Charting a course toward an uncertain future is always a risky business, especially among shoals of fiscal restraint or national tragedy, and the prudent navigator is well advised to remember where he's been as he looks ahead. The ocean and space sciences are poised for grand joint adventures, but shrinking budgets and the lingering Challenger numbness are restrictive lee shores that must be considered when laying plans. To sharpen the focus on future choices, it may be helpful to glance in the geophysical rearview mirror and remember some of the challenges and opportunities of a different era.A quarter century is a long time, but many images from 25 years ago can still be recalled in crisp detail, like photographs in a scrapbook. In 1961, results from the International Geophysical Year (IGY) filled the pages of the Transactions of the American Geophysical Union, and the U.S. program of space exploration finally was underway with conviction. The Indian Ocean Expedition, conceived during the IGY, ushered in a new era of international oceanography. The TIROS III satellite beamed to earth fuzzy pictures of tropical storms and revealed the intricate writhings of the Gulf Stream. Forecasters and fluid dynamicists suddenly saw new horizons, and geophysical turbulence became a major topic at the IUGG Symposium in Marseilles, France. Papers with prescient themes were presented at the AGU Ocean Section meeting: June Pattullo (then at Oregon State College, Corvallis) on heat storage in the Pacific; Ferris Webster (then at Woods Hole Oceanographic Institution, Woods Hole, Mass.) on Gulf Stream meanders. Polar oceanography was well represented in AGU journals: Kenneth Hunkins (at what was then called the Lamont Geological Observatory, Palisades, N.Y.) described the Alpha Rise, discovered from a drifting Arctic ice island, and Edward Thiel (then at the University of Minnesota, Minneapolis) and his co-workers discussed open ocean tides, gravimetrically measured from Antarctic

    Background: Ectodermal dysplasia (ED) is a group of rare, inherited disorders characterized by sparse hair, missing teeth and inability to sweat. Objective: To review and analyze cases of ED with an emphasis on clinical manifestations and parent's marriage history. Methodology: The present retrospective study was conducted by assessing the clinical records of nineteen cases of ED, available in the archives of the department; for age, gender, family history of consanguineous marriage and clinical manifestations. Results: It was observed that ED was more prevalent in males, with a ratio of 1.7:1. The hypohydrotic type was more common (78.95%) than hydrotic type (21.05%). The marriage history of parents revealed that 66.67% had consanguineous marriage and had 68.42% offspring's affected with ED; whereas 33.33% had history of non-consanguineous marriage and had 31.58% offspring's affected with ED. The clinical manifestations observed were- dry skin(94.74%); scaly skin(42.11%); sparse hair on scalp, eyebrows and eyelashes(100%); frontal bossing(63.18%); saddle nose (57.89%); hypertelorism (47.37%); nail abnormality(52.63%); normal sweat glands(21.05%); abnormal sweat glands(78.95%); hypoplastic maxilla(52.63%); protuberant lips (57.89%); palmo-plantar keratosis(21.05%); wrinkled & hyper pigmented facial skin(84.21%); partial anodontia(94.74%); conical shaped teeth(84.21%); high arched palate(68.42%); thin alveolar bone(100.00%); taurodontism(21.05%) and cleft lip & cleft palate(05.26%). The number of teeth present in all the cases ranged from 0 to 19. Conclusion: ED patients suffer from social problems and poor psychological and physiological development as a result of unacceptable esthetics and abnormal function of orofacial structures. Oral rehabilitation thus becomes mandatory, although it is often difficult; particularly in pediatric patients. PMID:24082749

    We compared treatment outcomes of two-dimensional radiotherapy (2D-RT), three-dimensional conformal radiotherapy (3D-CRT), and intensity-modulated radiotherapy (IMRT) in patients with nasopharyngeal carcinoma (NPC). In total, 1237 patients with cT1-4N0-3M0 NPC were retrospectively analyzed. Of these, 350, 390, and 497 were treated with 2D-RT, 3D-CRT, and IMRT, respectively. 3D-CRT and IMRT showed better 5-year overall survival (OS) rates (73.6 and 76.7 %, respectively) than did 2D-RT (5-year OS of 59.7 %, all p < 0.001). In T3-4 subgroup, IMRT was associated with a significantly better 5-year OS than was 2D-RT (70.7 vs. 50.4 %, respectively; p ≤ 0.001) and 3D-CRT (70.7 vs. 57.8 %, respectively; p = 0.011); however, the difference between the 2D-RT and 3D-CRT groups did not reach statistical significance (p = 0.063). In multivariate analyses of all patients, IMRT was a predictive factor for OS when compared with 2D-RT or 3D-CRT, as was 3D-CRT when compared with 2D-RT. Our study showed that 3D-CRT and IMRT were associated with a better local progression-free survival and OS than was 2D-RT in NPC. IMRT was significantly superior in terms of OS for advanced primary tumors (T3-4). (orig.)

    Full Text Available Numerous studies indicate that the transport factor significantly affects economic development and the development of market institutions. The history of mankind demonstrates that transport has always stimulated the socio-economic development of countries and regions, while changing the changing economic relations and people's needs, scientific and technological progress, in turn, contributed to the development of transport. In this regard, a special scientific interest is the study of the mutual influence of institutions and transport. Historical analysis has revealed a strong interdependence between transport and the establishment of institutions, primarily market ones. Water transport had been the catalyst for the market institutions development up to the time of industrial revolution. At the same time, the development of oceanic navigation in the XVI–XVII centuries had a different impact on the socio-economic development of the major maritime powers of that period (Portugal, Spain, Dutch republic, England. The industrial revolution strengthened the interdependence between transport and the factors of institutional development of advanced countries. The formation of the transport network and particularly the railway network as an innovative and the most «institutional» kind of transport in the most developed countries of that period (England, USA, France, has led these countries despite significant differences to very high positive economic results. This is explained by the essential coherence of the different variants of the capitalism existed in these countries, based on inclusive institutions. At the same time, private financing of the railway business required the consolidation of the efforts of many entrepreneurs. It stimulated the development of corporate institutions and the growth of joint-stock capital. Institutional features of the Russian Empire predetermined a special model of the railway network creation in the XIX century

    Percutaneous drainage of infected intraabdominal fluid collections is preferred over surgical drainage due to lower morbidity and costs. However, it can be a challenging procedure and catheter insertion carries the potential to contaminate the pleural space from the abdomen. This retrospective analysis demonstrates the clinical and radiographic correlation between percutaneous drainage of infected intraabdominal collections and the development of iatrogenic pleural space infections. A retrospective single institution analysis of 550 consecutive percutaneous drainage procedures for intraabdominal fluid collections was performed over 24 months. Patient charts and imaging were reviewed with regard to pleural space infections that were attributed to percutaneous drain placements. Institutional review board approval was obtained for conduct of the study. 6/550 (1.1%) patients developed iatrogenic pleural space infections after percutaneous drainage of intraabdominal fluid collections. All 6 patients presented with respiratory symptoms and required pleural space drainage (either by needle aspiration or chest tube placement), 2 received intrapleural fibrinolytic therapy and 1 patient had to undergo surgical drainage. Pleural effusion cultures revealed same bacteria in both intraabdominal and pleural fluid in 3 (50%) cases. A video with a dynamic radiographic sequence demonstrating the contamination of the pleural space from percutaneous drainage of an infected intraabdominal collection is included. Iatrogenic pleural space infections after percutaneous drainage of intraabdominal fluid collections occur at a low incidence, but the pleural empyema can be progressive requiring prompt chest tube drainage, intrapleural fibrinolytic therapy or even surgery. Expertise in intraabdominal drain placements, awareness and early recognition of this complication is critical to minimize incidence, morbidity and mortality in these patients.

    To report the renal structural and functional anomalies in children with multicystic dysplastic kidneys. Retrospective descriptive analysis of 47 children with multicystic dysplastic kidney seen in a pediatric nephrology unit over a period of 6 years. Antenatal diagnosis of multicystic dysplastic kidney was made in 34 (72.3%) patients. On follow up of 31 children for more than 12 months, 21 (68%) had involution, 4 [13%] had non-regression, and 4 (13%) were nephrectomized. Vesico-ureteric reflux (n=13; 28%) was the commonest renal abnormality. The serum creatinine values were higher (P=0.006) in children with contralateral reflux. Sub-nephrotic proteinuria was noted in 9 (29%) and was significantly associated with complete involution (P=<0.023). None of the patients developed hypertension and 2 (6.4%) had renal failure. Close nephrological follow-up is needed in children with multicystic dysplasia of kidneys.

  5. Imitation Modeling and Institutional Studies

    Maksim Y. Barbashin

    2017-09-01

    Full Text Available This article discusses the use of imitation modeling in the conduct of institutional research. The institutional approach is based on the observation of social behavior. To understand a social process means to determine the key rules that individuals use, undertaking social actions associated with this process or phenomenon. This does not mean that institutions determine behavioral reactions, although there are a number of social situations where the majority of individuals follow the dominant rules. If the main laws of development of the institutional patterns are known, one can describe most of the social processes accurately. The author believes that the main difficulty with the analysis of institutional processes is their recursive nature: from the standards of behavior one may find the proposed actions of social agents who follow, obey or violate institutions, but the possibility of reconstructive analysis is not obvious. The author demonstrates how the institutional approach is applied to the analysis of social behavior. The article describes the basic principles and methodology of imitation modeling. Imitation modeling reveals the importance of institutions in structuring social transactions. The article concludes that in the long term institutional processes are not determined by initial conditions.

    Introduction Emphysematous pyelophritis (EPN) is a serious condition with significant mortality. The prognosis of patients with EPN has changed over the years. Mortality has declined with prompt and aggressive medical management and minimally invasive strategies. Aim To identify the prognostic factors and assess the outcome of conservative management of emphysematous pyelonephritis. Settings and Design This was a retrospective study of 8 consecutive patients who were diagnosed with EPN in two medical institutes between July 2010 and June 2015. Materials and Methods Eight consecutive patients diagnosed with emphysematous pyelonephritis between July 2010 and June 2015 was studied retrospectively. On the basis of Computerised tomographic scan findings they were grouped into four classes (1 to 4) according the modified classification recommended by Huang and Tseng. The management was conservative (combination of percutaneous drainage and antibiotics), immediate nephrectomy or delayed nephrectomy (when conservative management failed). Demographic, clinical, biochemical and radiological characteristics were assessed and compared between survivors and nonsurvivors. Results Seven (87.5%) of a total of 8 patients had diabetes mellitus. Escherichia coli (71.4 %) was the most common offending pathogen identified in pus culture. With conservative management in 7 patients (combination of percutaneous drainage and antibiotics), treatment was successful in 57.14 % and with immediate nephrectomy (one patient), the success rate was 100%. The risk factors for mortality were thrombocytopenia, shock and altered sensorium at presentation. The mortality rate in class 1, 2 and 3 was 0%, 33.3% and 66.7%. None of the patient had class 4 EPN. Conclusion A combination of percutaneous drainage with antibiotics offers an effective therapy for emphysematous pyelonephritis. PMID:26675196

    Astronaut back pain is frequently reported in the early phase of space flight as they adapt to microgravity. The epidemiology of space adaptation back pain (SABP) has not been well established. This presentation seeks to determine the exact incidence of SABP among astronauts, develop a case definition of SABP, delineate the nature and pattern of SABP, review available treatments and their effectiveness in relieving SABP; and identify any operational impact of SABP. A retrospective review of all available mission medical records of astronauts in the U.S. space program was performed. It was revealed that the incidence of SABP has been determined to be 53% among astronauts in the U.S. space program; most cases of SABP are mild, self-limited, or respond to available treatment; there are no currently accepted preventive measures for SABP; it is difficult to predict who will develop SABP; the precise mechanism and spinal structures responsible for SABP are uncertain; there was no documented evidence of direction operational mission impact related to SABP; and, that there was the potential for mission impact related to uncontrolled pain, sleep disturbance, or the adverse side effects pf anti-inflammatory medications

    To evaluate the signalment, clinical signs, treatment, and outcome of dogs with urethral prolapse and identify risk factors associated with prolapse or treatment. Retrospective case series. Dogs (n = 48) with urethral prolapse. Medical records (May 1995-June 2010) from 2 referral centers were reviewed. Retrieved data included signalment, clinical signs, laboratory findings, treatment, complications, results of long-term follow-up. Records from Veterinary Medical Data Base (VMDB) were evaluated to determine odds ratios. Odds ratio for urethral prolapse in English bulldogs compared to all breeds was 366.99 (95% CI: 265.83, 506.65). Of 48 affected dogs, 46 had either resection and anastomosis (43 dogs) or urethropexy (3 dogs). The most common early postoperative complication was hemorrhage (39%); postoperative hemorrhage was less common when a simple continuous pattern was used for resection and anastomosis. Prolapse recurred in 57% of dogs available for long-term follow-up; recurrence was less common in dogs that were administered postoperative butorphanol or acepromazine. Gender was not associated with urethral prolapse or postoperative complications. Urethral prolapse occurs most commonly in English bulldogs. Postoperative hemorrhage and prolapse recurrence may be reduced with use of a simple continuous pattern for urethral anastomosis and by administration of postoperative sedation, respectively. Castration status did not appear to affect prolapse development or outcome. © Copyright 2014 by The American College of Veterinary Surgeons.

    The thyroid carcinoma (TC) is not very frequent among all cancer. Its course is slow and is high potentially curable. Our aim was to analyse the characteristics in patients with TC. A retrospective analysis on 171 patients, with an average age of 41.1. (± 14.6), who asked for TC to our service between the years 2000-2004, was performed. From case histories it was evaluated: anamnesis, diagnostic image, histopathology and evolution. Tumours were grouped for size and TNM (tumor-nodule-metastasis) in stage (S). A simulated serum thyroglobulin level >2 ng/ml and positive image with 131 I or another nuclear marker were considered as positive for residual TC. In the totality of the analyzed patients 88% were female, 62% below 45 years old, and in 77% the thyroid function was normal. The fine needle aspiration (FNA) was diagnostic in 78%. Papillary thyroid carcinoma (PTC) in 96%. The 63% was SI; 14% SII; 19% SIII and 4% SIV. During follow-up, we observed that 90% of patients with Tg between 2 and 10 had evidence of residual TC, and 100% with Tg > 10 ng/ml, whereas 18% of those whose simulated Tg [es

    Palliative irradiation of osteolytic lesions is a considerable component in the treatment for patients with multiple myeloma. In this study, we analyzed the efficacy of irradiation in these patients. We retrospectively analyzed 153 patients with multiple myeloma who were admitted to our department between 1989 and 2013. According to the staging system of Durie & Salmon 116 patients were classified as stage III. 107/153 patients were treated with radiotherapy of at least one and up to 6 bony lesions at different times. In order to evaluate the effect of local radiotherapy on pain relief and bone recalcification a uni- and multivariate analysis was performed using a binary logistic regression model to correct for multiple measurements. Complete information on dose, fractionation and volume of radiotherapy was available from 81 patients treated in 136 target volumes for pain relief, and from 69 patients treated in 108 target volumes for recalcification. Total radiation doses varied between 8 Gy to 50 Gy (median dose 25 Gy in 2.5 Gy fractions, 5 times a week). Radiotherapy resulted in complete local pain relief in 31% and partial local pain relief in 54% of the patients. In the univariate analysis, higher total radiation doses (p = 0.023) and higher age (p = 0.014) at the time of radiotherapy were significantly associated with a higher likelihood of pain relief, whereas no significant association was detected for concurrent systemic treatment, type and stage of myeloma and location of bone lesions. The same variables were independent predictors for pain relief in the multivariate analysis. Recalcification was observed in 48% of irradiated bone lesions. In the uni- and multivariate analysis higher radiation doses were significantly associated (p = 0.048) with an increased likelihood of recalcification. Side effects of radiotherapy were generally mild. Higher total biological radiation doses were associated with better pain relief and recalcification in this

    The aim of this study was to evaluate 12 years of general practitioner (GP) use of open access MRI services at a single London teaching hospital. A retrospective analysis of reports from all GP requests for MRI scans between 1994 and 2005 was performed. The date, scanned body part, and requester details from 1798 scans requested by 209 individual GPs over a continuous 12-year period were recorded. All scans were then graded into four categories based on the severity of reported findings from normal to gross abnormality. Over the study period, GP requests as a percentage of the total (MRI) department workload remained low at approximately 2.6%. Spine, knee and brain requests constituted 86% (n = 1546) of requested scans. 48% (n = 868) of scans were reported as normal or minor degenerative changes only. 26% (n = 466) of scans demonstrated serious pathology that was likely to warrant hospital consultant referral. There was a wide range of scans requested per requester, from 1 to 240 over the period, with an average of 8.5 scans per GP. In conclusion, any department wishing to set up open access to MRI services for GPs could cover the majority of requests by offering spine, knee and brain imaging. The percentage of normal report rates for GP requests is comparable with previous studies of outpatient referrals. A large variation in requesting patterns between GPs suggests the need for increased communication between GPs and imaging departments to optimise use of the service.

    Uterine-sparing procedures could be attractive in patients concerned about preservation of fertility and change in corporeal image and sexuality. Transvaginal uterosacral hysteropexy can provide an alternative mesh-free technique for uterine suspension. This study aimed to evaluate the feasibility of transvaginal uterine suspension to uterosacral ligaments in terms of operative data, complications, midterm efficacy, and patient satisfaction. This retrospective study analyzed the first 20 cases of transvaginal hysteropexy through bilateral high uterosacral ligaments (modified Shull technique) performed in our Institution. Mean follow-up was 33.2 months. The procedure was performed in 84 ± 19 min ,and blood loss was 228 ± 139 ml. Three mild complications (15 %) were observed. Recurrence [Pelvic Organ Prolapse Quantification system (POP-Q) stage ≥ II was observed in five patients (25 %), and three of them (15 %) required reintervention. Mean Patient Global Impression of Improvement score was "much improved." Two woman (40 %) who had not fulfilled their childbearing desire obtained a pregnancy. Both underwent elective caesarean section at term. Transvaginal uterosacral hysteropexy appears a feasible mesh-free technique for apical support. This procedure can be indicated in women with the desire of preserving fertility or who prefer a uterine-sparing surgical option.

    Introduction In 2015, the authors reported the results of a preliminary investigation of preventable disaster deaths (PDDs) at medical institutions in areas affected by the Great East Japan Earthquake (2011). This initial survey considered only disaster base hospitals (DBHs) and hospitals that had experienced at least 20 patient deaths in Miyagi Prefecture (Japan); therefore, hospitals that experienced fewer than 20 patient deaths were not investigated. This was an additional study to the previous survey to better reflect PDD at hospitals across the entire prefecture. Of the 147 hospitals in Miyagi Prefecture, the 14 DBHs and 82 non-DBHs that agreed to participate were included in an on-site survey. A database was created based on the medical records of 1,243 patient deaths that occurred between March 11, 2011 and April 1, 2011, followed by determination of their status as PDDs. A total of 125 cases of PDD were identified among the patients surveyed. The rate of PDD was significantly higher at coastal hospitals than inland hospitals (17.3% versus 6.3%; Pdisaster deaths in non-DBHs were most numerous in facilities with few general beds, especially among patients hospitalized before the disaster in hospitals with fewer than 100 beds. Categorized by area, the most frequent causes of PDD were: insufficient medical resources, disrupted lifelines, delayed medical intervention, and deteriorated environmental conditions in homes and emergency shelters in coastal areas; and were delayed medical intervention and disrupted lifelines in inland areas. Categorized by hospital function, the most frequent causes were: delayed medical intervention, deteriorated environmental conditions in homes and emergency shelters, and insufficient medical resources at DBHs; while those at non-DBHs were disrupted lifelines, insufficient medical resources, delayed medical intervention, and lack of capacity for transport within the area.

    Nausea and vomiting are among the most problematic symptoms experienced by patients with cancer who are receiving chemotherapy. 5-hydroxytryptamine 3(5-HT3)-receptor antagonists, NK1 receptor antagonists(aprepitant)and dexamethasone are now the standard therapies for preventing chemotherapy-induced nausea and vomiting(CINV)that follow highly emetogenic chemotherapy, such as cisplatin and anthracycline. However, since it is not cleared which 5-HT3-recepter antagonist is a proper treatment for combined use with aprepitant and dexamethasone, we conducted a questionnaire survey, which used the numerical rating scale(NRS), for comparing palonosetron with granisetron in the same patient. Palonosetron showed a significant improvement of nausea for both acute(within 24 hours)and delayed phase(24-120 hours later), regardless of the type of chemotherapy(cisplatin or anthracycline-based regimen). Furthermore, palonosetron had a tolerable safety profile. Our study suggests that palonosetron-based antiemetic treatment will be a preferred choice for preventing CINV following highly emetogenic chemotherapy.

    Leptospirosis is a bacterial disease transmitted to humans and animals by direct or indirect contact with urine or body fluids from infected animals especially rodents. Infection can be associated with wide clinical spectrum varying from asymptomatic to severe multi-organ syndrome with life-threatening consequences. We conducted a review of published studies on incidences, case reports, sero-epidemiological surveys from year 2000 to 2015 using different electronic data bases. Our study revealed that majority of the studies were conducted in Peninsular Malaysia and predominantly among high-risk human groups. Most of the studies on domestic animals were conducted in the 1980s; hence, the current status of leptospirosis among domestic animal population remains largely unknown. There tend to be a sharp rise in incidence rate among human population in the year 2014 which was attributed to flooding and heavy rainfall experienced as well as recreational activities. Several gaps in epidemiological knowledge were also disclosed.

    There is a lack of evidence regarding factors associated with failure of tracheostomy decannulation. We aimed to identify characteristics of pediatric patients who fail a tracheostomy decannulation challenge Methods: A retrospective review was performed on all patients who had a decannulation challenge at a tertiary care center from June 2006 to October 2013. Tracheostomy decannulation failure was defined as reinsertion of the tracheostomy tube within 6 months of the challenge. Data on demographics, indications for tracheostomy, home mechanical ventilation, and comorbidities were collected. Data were also collected on specific airway endoscopic findings during the predecannulation bronchoscopy and airway surgical procedures before decannulation. We attempted to predict the decannulation outcome by analyzing associations. 147 of 189 (77.8%) patients were successfully decannulated on the first attempt. Tracheostomy performed due to chronic respiratory failure decreased odds for decannulation failure (odds ratio = 0.34, 95% confidence interval = 0.15-0.77). Genetic abnormalities (45%) and feeding dysfunction (93%) were increased in the population of patients failing their first attempt. The presence of one comorbidity increased the odds of failure by 68% (odds ratio = 1.68, 95% confidence interval = 1.23-2.29). Decannulation pursuit based on parental expectation of success, rather than medically determined readiness, was associated with a higher chance of failure (P = 0.01). Our study highlights the role of genetic abnormalities, feeding dysfunction, and multiple comorbidities in patients who fail decannulation. Our findings also demonstrate that the outcome of decannulation may be predicted by the indication for tracheostomy. Patients who had tracheostomy placed for chronic respiratory support had a higher likelihood of success. Absence of a surgically treatable airway obstruction abnormality on the predecannulation bronchoscopy increased the

    To determine the trends in youth suicide in Victoria and Australia as a whole, and their relation to youth unemployment. We used Australian Bureau of Statistics data to analyse suicide trends between 1907 and 1990 in young people aged 15-24 years and made an in-depth study of youth suicides between 1980 and 1990, for which computerised data are available. There has been a steady increase in youth suicide both in Victoria and Australia as a whole since 1960 in males but not females. There were significant differences in age, sex and area of residence in both the rate and the method of suicide. The increase in youth suicide was not associated with the rise in unemployment. Male (not female) suicide rates were higher in non-metropolitan areas and areas of high youth unemployment. The reasons for the increase in youth suicide remain obscure. There is a need for a prospective in-depth study to determine factors in the aetiology of youth suicide, with particular reference to possible areas for prevention.

    Aims: To study the differences in the imaging features of spread from the three cancer cell lines, namely epithelial, sarcomatoid, and lymphoid, resulting in peritoneal carcinomatosis, peritoneal sarcomatosis, and peritoneal lymphomatosis, respectively. Materials and methods: In this institutional review board-approved Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective study, an electronic radiology database was searched to identify patients with peritoneal tumour spread who underwent CT imaging at Dana-Farber Cancer Institute, a tertiary cancer institution, between January 2011 and December 2012. Out of 1214 patients with possible peritoneal tumour spread on the radiology reports, 122 patients were included with histopathologically confirmed peritoneal disease (50 randomly selected patients with peritoneal carcinomatosis and sarcomatosis each, and all 22 patients with lymphomatosis). Two blinded, fellowship-trained radiologists in consensus reviewed the CT images in random order and recorded the imaging findings of peritoneal tumour spread. The statistical analysis was performed in two steps: the first comparing incidence of various features in each group and the second step was a pairwise analysis between each cohort. Results: Peritoneal carcinomatosis more frequently had ascites, peritoneal thickening, and omental cake (all p ≤ 0.001). Measurable nodules were less common in peritoneal carcinomatosis (p < 0.001), and when present, were ill-defined and had an irregular outline (p ≤ 0.002). Peritoneal sarcomatosis more often had discrete nodules that were well defined and had a smooth outline and less frequently had ascites, peritoneal thickening, omental caking, serosal implants, and lymphadenopathy (all p ≤ 0.005). Peritoneal lymphomatosis frequently involved the omentum and mesentery, and often had associated lymphadenopathy and splenomegaly (all p ≤ 0.002). Conclusion: Peritoneal carcinomatosis, sarcomatosis

    Perceptions of institutions that manage hazards are important because they can affect how the public responds to hazard events. Antecedents of trust judgments have received far more attention than antecedents of attributions of responsibility for hazard events. We build upon a model of retrospective attribution of responsibility to individuals to examine these relationships regarding five classes of institutions that bear responsibility for food safety: producers (e.g., farmers), processors (e.g., packaging firms), watchdogs (e.g., government agencies), sellers (e.g., supermarkets), and preparers (e.g., restaurants). A nationally representative sample of 1,200 American adults completed an Internet-based survey in which a hypothetical scenario involving contamination of diverse foods with Salmonella served as the stimulus event. Perceived competence and good intentions of the institution moderately decreased attributions of responsibility. A stronger factor was whether an institution was deemed (potentially) aware of the contamination and free to act to prevent or mitigate it. Responsibility was rated higher the more aware and free the institution. This initial model for attributions of responsibility to impersonal institutions (as opposed to individual responsibility) merits further development. © 2014 Society for Risk Analysis.

    Full Text Available As violence in society is increasing in recent years it is an important problem in health institutions as well. Changes in health systems, rising socio-economic levels of people, and changes in expectations for health services led to violence in health sector. This study was conducted for the purpose of examining work place violence against health care workers. This retrospective-descriptive study covers a period from December 2011 to April 2015. 136 notifications about work place violence reported by health workers to quality management unit of a hospital were taken into account. Research findings show that 43,4% of the victims of violence was physicians, 37,5% was nurses and health officers and 19,1% were from other professions. 63,2% of the health workers were women, 36,8% were male. Additionally health workers were exposed to violence by 47.3% of the patients and 52.7% by their relatives. 69.7% of the people applied violence were male and 30.3% were female. 63,2% of the health workers exposed to violence were women, 36,8% were male. According to our results male physicians were exposed to workplace violence more than other workers and this was significant ( χ 2=31,634, p<0,01. When place of violence occurred was investigated it was seen that while most of physicians were exposed to violence in polyclinics, nurses were exposed to violence in inpatient services (χ2=18,231, p<0,01. Male physicians were exposed to verbal violence most. On the other hand nurses experienced both verbal and physical violence (χ2=34,639,p<0.01. Patient relatives applied verbal violence and the others applied physical violence (χ2=22,073, p<0,01. As a result, in order to reduce / prevent violence in work place , it is considered necessary to increase consciousness of patients and their relatives, to increase security measures in health institutions, to provide health workers to report work place violence to management , to improve physical working conditions and

    2017-01-01

    Children are at higher risk of renal injury from blunt trauma than adults due to a variety of anatomic factors such as decreased perirenal fat, weaker abdominal muscles, and a less ossified thoracic cage. Non-operative management is gaining in popularity for even major injuries, although there are no universally accepted guidelines. We present a retrospective review of pediatric major blunt renal injuries (grade 3 or higher) at a children's hospital in Hawai‘i over a 5-year period. Medical records were examined between January 2009 and September 2014 from Kapi‘olani Medical Center for Women and Children in Honolulu, Hawai‘i. Inclusion criteria were a diagnosis of renal trauma, or the diagnosis of blunt abdominal trauma with hematuria. Exclusion criteria were grade I or II renal injury or death due to an additional traumatic injury. Mechanism of injury, clinical characteristics on admission, blood product requirements, surgical interventions performed, and hospital length of stay were retrospectively analyzed. Eleven total patient records were examined, nine of which fit inclusion criteria. Uniquely, 33% of patients sustained their renal injury while surfing. No patients required laparotomy or nephrectomy, though 22% of patients received a blood transfusion and 44% of patients underwent ureteral stent placement. Non-operative management of major renal injuries in children is feasible and allows for preservation of renal tissue. A novel mechanism of surfing as a cause of major renal trauma is seen in the state of Hawai‘i. PMID:28484665

    The aim of this retrospective study was to define the natural history, clinicopathological findings, prognostic factors, and treatment outcome of 43 patients with localized stages I and II primary non-Hodgkin's lymphoma (NHL) of the nasopharynx, followed up in a single institution over a 17-year period. Forty-three (13 women and 30 men) consecutive patients with localized stages I (N = 12) and II (N = 31) primary nasopharyngeal NHL were treated in our institution between 1990 and 2007. The pathologic reports were classified according to the International Working Formulation (N = 22) or Revised European-American Lymphoma classification (N = 21). The vast majority of patients (88%) were managed with a sequential combination of chemotherapy and radiation therapy. Chemotherapy mainly consisted of 4-8 (median 6) cycles of CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisolone). Involved-field radiation therapy with a median dose of 44 Gy was delivered to the primary site and entire cervical lymph nodes. The median age of the patients was 53 years (range, 6 to 86 years). The majority of the patients (70%) had high-grade histology. B-cell types represented 67% of the cases, among which diffuse large B cell was the most common histological subtype. After a median follow-up of 70 months, the 5-year disease-free survival and overall survival were 58.8% and 70.6%, respectively. In multivariate analysis, age less than or equal to 30 years (hazard ratio (HR) = 5.32, 95% confidence interval (CI) = 1.69-16.76), elevated serum lactate dehydrogenase level (HR = 3.69, 95% CI = 1.43-9.51), and modified International Prognostic Index with more than or equal to two risk factors (HR = 17.99, 95% CI = 2.32-139.30) retained statistical significance. Our limited data suggest that primary nasopharyngeal NHL tends to have aggressive histology and unfavorable clinical course with poor outcome, despite a considerably localized disease at the time of presentation and high

    Although opinions preferring individual administration of activity in the treatment of thyroid cancer with 131 I predominate, sufficient quantitative arguments in favor of this approach are unavailable as yet. Therefore, a retrospective study involving statistical processing was proposed with the aim to evaluate the relations between available data of the patients and success of treatment. Ideally, recommendations regarding activity to be administered in dependence on the biophysical status of the patient should emerge from the study

    A retrospective analysis of oral cysts that were seen over an 11-year period in children at a dental institution in Nigeria was carried out. In general, oral cysts accounted for only 2.6% of the total biopsied lesions during the period under review. The most common oral cysts were the mucous retention cysts, the gingival cysts of infants and the dentigerous cyst. The commonest sites were the maxilla, the mandible and the floor of the mouth respectively and there was no significant difference in sex preference. Most of the cases were seen in the age group 11-16 years while the least was in the group aged 6-10 years.

    Biologic fertility can be measured using time to pregnancy (TTP). Retrospective designs, although lacking detailed timed information about behavior and exposure, are useful since they have a well-defined target population, often have good response rates, and are simpler and less expensive...... at the beginning of unprotected intercourse. More complete inference is possible if the study design covers the whole population, not just those who achieve a pregnancy....

    Full Text Available Introduction. Pre-term premature rupture of membranes (PPROM is one of the leading causes of perinatal morbidity and mortality. This complication is diagnosed in 3% of pregnant women in Kazakhstan, and it is the leading cause of pre-term deliveries. The aim of this study was to determine the outcomes of pregnancies complicated by PPROM in gestation periods between 24 to 32 weeks among three institutions in Kazakhstan.Methods. This is descriptive analysis of 154 cases with PPROM observed between 24 to 32 weeks of gestation at Perinatal Centers #2 and #3 and the National Research Center for Maternal and Child Health, Astana, Kazakhstan. Cases were selected on the basis of retrospective chart review where PPROM diagnosis occurred in 2013. Descriptive statistics were utilized for data analysis.Results. The most frequent complications associated with PPROM were threat of miscarriage (13.6% of cases and chronic placental insufficiency (7.8%. The mean time between PPROM and onset of spontaneous labor was 12.1 ± 2.3 days.  Spontaneous labor within 3 days after PPROM started in patients with an amniotic fluid index of 3.0 ± 0.2 cm. Complications experienced by PPROM women during delivery and early postpartum period included: precipitous labor (6.4%, weakness of labor activity (16.2%, atonic hemorrhage (1.2%, and chorioamnionitis (3.2%. 37.6% of newborns in this study were admitted to the Intensive Care Unit. Their health complications included pneumonia (7.7%, conjunctivitis (1.3%, omphalitis and infectious-toxic shock (3.8%, intraventricular hemorrhage  (7.8%, and respiratory distress (10.3% .Conclusion. Thus, preterm rupture of membranes is associated with preterm delivery and an increase of neonatal morbidity. Therefore, it is necessary to find ways to effectively manage PPROM, including developing new techniques to restore the amniotic fluid volume in women experiencing PPROM during 24 to 32 weeks of gestation.

    Full Text Available Background. Autoimmune process and immunosuppressive therapy of pemphigus vulgaris would predispose the patients to infections. Aim. We aimed to study the prevalence of infection and pathogenic agents in pemphigus vulgaris patients admitted to dermatology service. Material and methods. This retrospective study was conducted on 155 pemphigus vulgaris patients (68 males, 87 females admitted to dermatology service between 2009 and 2011. In this study, the diagnosis of pemphigus vulgaris was confirmed by light microscopic and direct immunofluorescence findings. Data were collected through a questionnaire. Results. Of 155 pemphigus vulgaris patients, 33 had infection at admission and 9 acquired nosocomial infection. In addition, 37 cases of oral candidiasis and 15 cases of localized herpes simplex were recorded. Totally, 94 cases of infection were recorded. The occurrence of infection was significantly related to the severity of disease, number of hospital admissions, and presence of diabetes mellitus. The most common pathogenic germs isolated from cultures were Staphylococcus aureus and Escherichia coli. Conclusion. Severity of pemphigus vulgaris and diabetes were directly related with tendency to infections. Staphylococcus aureus and Escherichia coli were the most common pathogenic agents. Due to limitations of retrospective study, a prospective study is recommended.

    Full Text Available Objective: A retrospective study detailing the circumstances surrounding diagnosis and treatment of pheochromocytomas with the associated genetic disorders. Materials and Methods: All patients with surgically excised pheochromocytomas in the Health Sciences Center, St. John′s, Newfoundland, Canada between January 2001 and December 2010 were retrospectively analyzed to determine associated familial syndromes, age, tumor size, symptomatology, and percentage of paragangliomas and bilateral pheochromocytomas. Pathology specimen reports, adrenalectomy lists and Meditech (electronic medical record diagnostic codes provided a comprehensive database for this study. Results: Twenty-four patients were studied; familial disorder patients comprised 42% (10/24. Average age at diagnosis was 57 among the sporadic and 34 in familial disorder groups (P = 0.006. Average tumor size was 4.5 cm in the sporadic group and 3 cm in the familial disorder group (P = 0.19. All atypical cases including bilateral or extra-adrenal tumors and malignancy occurred in familial disorder patients. Conclusions: The proportion of familial disorder patients (42% was higher in this study than would be expected, likely a result of the relatively high incidence of hereditary autosomal dominant disorders within Newfoundland. Among familial disorder patients, the average younger age at diagnosis and the smaller tumor size suggest syndromic pheochromocytomas may develop earlier, however they are more likely to be diagnosed sooner due to biochemical surveillance testing in known genetic disorder patients. We also demonstrate a relatively high incidence of surgically resected pheochromocytomas of 4.679/million/year in Newfoundland.

    Methotrexate, a folate antimetabolite, is used to treat atopic dermatitis and psoriasis. Although methotrexate's therapeutic efficacy has been noted in the literature, there are few data on the efficacy of methotrexate treatment for allergic contact dermatitis. To evaluate the efficacy and tolerability of methotrexate in treating allergic contact dermatitis at a single institution, and also to assess methotrexate efficacy in patients with chronic, unavoidable allergen exposure. We performed a retrospective chart review of 32 patients diagnosed with allergic contact dermatitis by positive patch test reactions, and who received treatment with methotrexate from November 2010 to November 2014. Demographic and treatment-associated data were collected from electronic medical records. Ten patients were identified as allergen non-avoiders secondary to their occupation, and were subgrouped as such. Seventy-eight per cent (25/32) of patients showed either a partial or a complete response. Methotrexate had a comparable efficacy rate in the allergen non-avoiders subset, at 10 of 10. Of the 32 patients, 23% (5/22) had complete clearance of their dermatitis, and 1/10 of allergen non-avoiders had complete clearance of their dermatitis. Methotrexate is a well-tolerated and effective treatment for allergic contact dermatitis, and shows comparable efficacy to immunomodulatory agents such as cyclosporine and azathioprine, with robust efficacy despite persistent allergen exposure in patients with allergic contact dermatitis. © 2017 John Wiley & Sons A/S.

    We report our experience of diagnosing and treating hepatic angiomyolipoma (HAML), a rare benign mesenchymal tumor. We analyzed retrospectively the clinicopathologic, radiological, and operative data of 25 patients who underwent surgery for HAML at our institute between November 2001 and May 2006. Most patients (20/25) were asymptomatic and had normal liver function. Ultrasonography (US) showed a heterogeneous hyperechoic mass in 13 of 23 patients, precontrast computed tomography (CT) showed that all of 12 lesions scanned were hypodense, and magnetic resonance imaging (MRI) showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images in most (5/6) lesions. Marked enhancement in the arterial phase was seen in 10 of 12 lesions on CT scans and in 6 of 6 lesions on MRI scans. All tumors were composed of varying proportions of smooth muscle, adipose tissue, and blood vessels, and showed positive immunohistochemical staining for HMB-45. All patients underwent partial hepatectomy and there was no evidence of recurrence after a median follow-up of 43 months. The radiological features of HAML vary according to its histological components. The definitive diagnosis of HAML is challenging and depends on the presence of HMB-45-positive myoid cells. Hepatic angiomyolipoma is treated effectively with surgery and the prognosis is good. (author)

    Purpose: The objective of this study was to report our experience with stereotactic radiosurgery performed with the Gamma Knife (GK) in the treatment of patients with brain metastases and to compare survival for those treated with radiosurgery alone with survival for those treated with radiosurgery and whole-brain radiotherapy. Methods and Materials: Prospectively collected demographic and clinical characteristics and treatment and survival data on 237 patients with intracranial metastases who underwent radiosurgery with the GK between 2003 and 2007 were reviewed. Kaplan-Meier and Cox proportional hazards regression analyses were used to compare survival by demographic and clinical characteristics and treatment. Results: The mean age of the patient population was 56 years. The most common tumor histologies were non-small-cell lung carcinoma (34.2%) and breast cancer (13.9%). The median overall survival time was 8.5 months from the time of treatment. The median survival times for patients with one, two/three, and four or more brain metastases were 8.5, 9.4, and 6.7 months, respectively. Patients aged 65 years or greater and those aged less than 65 years had median survival times of 7.8 and 9 months, respectively (p = 0.008). The Karnofsky Performance Score (KPS) at the time of treatment was a significant predictor of survival: those patients with a KPS of 70 or less had a median survival of 2.9 months compared with 10.3 months (p = 0.034) for those with a KPS of 80 or greater. There was no statistically significant difference in survival between patients treated with radiosurgery alone and those treated with radiosurgery plus whole-brain radiotherapy. Conclusions: Radiosurgery with the GK is an efficacious treatment modality for brain metastases. A KPS greater than 70, histology of breast cancer, smaller tumor volume, and age less than 65 years were associated with a longer median survival in our study.

    Background: Utilization of health services is the actual attendance by the members of the public at health care facilities to receive care. Utilization, serves as an important tool for oral health policy decision-making. The aim of the present study was to retrospectively gauge and assess the utilization pattern of the dental treatments which was given in hospital for last 10 years. Materials and Methods: This retrospective infirmary based study was carried out at Sheri Kashmir Institute of Medical Sciences (SKIMS), Srinagar, Jammu and Kashmir, India. The yearly outpatient department (OPD) records for the utilization of specific dental treatment of a total of 103963 patients were assessed retrospectively from 2014 to 2003. Trend analysis was used to assess the trend of utilization of each speciality with best fitted linear trend lines. Results: The pattern of new patients has also shown a constant rise during the study period except for 2008 and 2009. The utilization of oral surgery speciality has shown a tremendous fall from 2003 to 2014 whereas the number of patients coming to periodontics and conservative dentistry has shown an increasing pattern. Conclusion: Utilization of oral health care has long been used as an indicator of oral health related behaviour of a population. In the present study it can be conclude that the outlook of the population under study has changed from blood and vulcanite dentistry outlook and is moving towards restorative dentistry. .

    An apparent increased risk for developing Amyotrophic Lateral Sclerosis (ALS), a multifactorial neurodegenerative disease, is considered to exist in the military population. ALS military and veteran patients were retrospectively recruited in April 2008 by searching medical data (Hippocrate) and repayment data (Erasme) of the French National Military Health Care Fund (Caisse nationale militaire de sécurité sociale, CNMSS) from de January 1991 to December 2007. We report a series of 73 patients, 69 male and four female, average age of 52.5 years (range 27 to 72 years) with a peak of patients in the 50-59 year age class. The branch of military service was Army (n=26 patients), Air force (n=14), Navy (n=10) and State Police Force (n=22). The incidence among male active duty military personnel was stable from 2002 to 2007; it was less than the general population (1.7/100,000 per year in 2007), but higher in the 40-44 and 50-54 year age classes (1.90 and 5.07/100,000 per year in 2007 respectively). Duration of active duty was on average 31 years. The retrospective nature of the data and the incomplete population with loss of retired military personnel without CNMSS affiliation are limitations of our study. Another means of collecting all cases of ALS among French military personnel and veterans would be to conduct a search in the 17 ALS centers in France with analysis by occupational activity for entire career.

    The treatment of endometrial cancer (EC) is challenging. There is no standard of care for patients who progressed after carboplatin and paclitaxel (CT) and all available drugs show a small response and poor long-term survival in this scenario. The objective of this study was to evaluate the efficacy and toxicity profile of palliative doxorubicin after progression to CT therapy in advanced or recurrent EC. A retrospective review of the Brazilian National Cancer Institute database between 2009 and 2013 was performed, and all patients with recurrent and advanced EC treated with palliative doxorubicin after progression on CT were included. Progression-free survival (PFS), overall survival (OS), objective response rates as well as toxicity were evaluated. A total of 33 patients were enrolled, with a median age of 65.7 years. Objective responses were documented in 12.1% (3.0% of complete responses and 9.1% of partial responses). The median PFS was 4.4 months, and the median OS was 8.1 months for patients exposed to doxorubicin. The most common adverse event was anemia observed in 60.6% of patients. This retrospective study suggests that doxorubicin has a modest activity in patients with advanced or recurrent EC after treatment with CT.

    The 2011, magnitude (M) 9, Great East Japan Earthquake and massive tsunami caused widespread devastation and left approximately 18,500 people dead or missing. The incidence of preventable disaster death (PDD) during the Great East Japan Earthquake remains to be clarified; the present study investigated PDD at medical institutions in areas affected by the Great East Japan Earthquake in order to improve disaster medical systems. A total of 25 hospitals in Miyagi Prefecture (Japan) that were disaster base hospitals (DBHs), or had at least 20 patient deaths between March 11, 2011 and April 1, 2011, were selected to participate based on the results of a previous study. A database was created using the medical records of all patient deaths (n=868), and PDD was determined from discussion with 10 disaster health care professionals. A total of 102 cases of PDD were identified at the participating hospitals. The rate of PDD was higher at coastal hospitals compared to inland hospitals (62/327, 19.0% vs 40/541, 7.4%; Pdeath at medical institutions in areas affected by the Great East Japan Earthquake occurred mainly at coastal hospitals. Insufficient resources (at GHs), environmental factors (at coastal hospitals), and delayed medical intervention (at all hospitals) constituted the major potential contributing factors. Further investigation of all medical institutions in Miyagi Prefecture, including those with fewer than 20 patient deaths, is required in order to obtain a complete picture of the details of PDD at medical institutions in the disaster area.

The sites of injury include the foot in sixpatients (35.3%, the hand in six patients (35.3% and the facial region in five patients (29.4%.Seven patients with second-degree frostbite were completely cured with only conservativetreatment during a mean period of 12.7±3.3 days (range, 8-16 days. Of the five patients withthird-degree frostbite, two underwent skin grafting following debridement, and the remainingthree achieved a complete cure with conservative treatment during a mean period of 35±4.3days (range, 29-39 days. Five patients with fourth-degree frostbite were treated with surgicalprocedures including amputation.Conclusions With the appropriate conservative management in the early stage of onset,surgeons should decide on surgery after waiting for a sufficient period of time until thedemarcation of the wound. Continuous management of patients is also needed to achievefunctional recovery after a complete cure has been achieved. This should also be accompaniedby patient education for the avoidance of re-exposure to cold environments.

    No cases of lung cancer or mesothelioma have ever been diagnosed or compensated as asbestos-related in Lithuania. This paper attempts to estimate the proportion of those occupationally exposed to asbestos among respiratory cancer patients. Occupational exposure to asbestos was assessed retrospectively for 218 lung cancer and 2 mesothelioma patients admitted to Institute of Oncology, Vilnius University. The evaluation was based on personal interview data using an internationally established questionnaire. Cumulative exposure to asbestos at work was evaluated in fibre-years. A cumulative asbestos exposure of ≥25 fibre-years was found for 7 patients (3.2%), in further 135 (61.2%) a cumulative exposure from 0.01 to 24.99 fibre-years was assessed. The most common occupations among heavily (≥25 fibre-years) exposed patients were smith, welder or insulator in foundries, construction, shipyard as well as asbestos cement and glass industry. Preliminary findings indicate that a fraction (3.2%) of the respiratory cancer cases could be attributed to occupational exposure to asbestos. Since 1560 or more cases of lung cancer are registered every year in Lithuania, about 50 cases per year could be predicted to be asbestos-related. (author)

    Purpose: During the first part of the 20th century, {sup 226}Ra was the most used radionuclide for brachytherapy. Retrospective accurate dosimetry, coupled with patient follow up, is important for advancing knowledge on long-term radiation effects. The purpose of this work was to dosimetrically characterize two {sup 226}Ra sources, commonly used in Sweden during the first half of the 20th century, for retrospective dose–effect studies. Methods: An 8 mg {sup 226}Ra tube and a 10 mg {sup 226}Ra needle, used at Radiumhemmet (Karolinska University Hospital, Stockholm, Sweden), from 1925 to the 1960s, were modeled in two independent Monte Carlo (MC) radiation transport codes: GEANT4 and MCNP5. Absorbed dose and collision kerma around the two sources were obtained, from which the TG-43 parameters were derived for the secular equilibrium state. Furthermore, results from this dosimetric formalism were compared with results from a MC simulation with a superficial mould constituted by five needles inside a glass casing, placed over a water phantom, trying to mimic a typical clinical setup. Calculated absorbed doses using the TG-43 formalism were also compared with previously reported measurements and calculations based on the Sievert integral. Finally, the dose rate at large distances from a {sup 226}Ra point-like-source placed in the center of 1 m radius water sphere was calculated with GEANT4. Results: TG-43 parameters [including g{sub L}(r), F(r, θ), Λ, and s{sub K}] have been uploaded in spreadsheets as additional material, and the fitting parameters of a mathematical curve that provides the dose rate between 10 and 60 cm from the source have been provided. Results from TG-43 formalism are consistent within the treatment volume with those of a MC simulation of a typical clinical scenario. Comparisons with reported measurements made with thermoluminescent dosimeters show differences up to 13% along the transverse axis of the radium needle. It has been estimated that

    Elderly and low Karnofsky performance status (KPS) patients have been excluded from most prospective trials. This retrospective study investigated glioblastoma treatment outcomes, including those of elderly and low KPS patients, and analyzed the prognostic factors using the medical records of 107 consecutive patients, 59 men and 48 women aged from 21 to 85 years (median 65 years), with newly diagnosed glioblastoma treated at our institute. There were 71 high-risk patients with age >70 years and/or KPS 6 -methylguanine-deoxyribonucleic acid methyltransferase-negative (p=0.027), and more than subtotal removal (p=0.003) were significant prognostic factors. The median postoperative KPS score tended to be better than the preoperative score, even in the high-risk group. We recommend maximal safe resection for glioblastoma patients, even those with advanced age and/or with low KPS scores. (author)

    This retrospective study summarizes 11 cases of end-stage renal disease (ESRD) in captive polar bears (Ursus maritimus) from eight zoologic institutions across the United States and Canada. Ten bears were female, one was male, and the mean age at the time of death was 24 yr old. The most common clinical signs were lethargy, inappetence, and polyuria-polydipsia. Biochemical findings included azotemia, anemia, hyperphosphatemia, and isosthenuria. Histologic examination commonly showed glomerulonephropathies and interstitial fibrosis. Based on submissions to a private diagnostic institution over a 16-yr period, ESRD was the most commonly diagnosed cause of death or euthanasia in captive polar bears in the United States, with an estimated prevalence of over 20%. Further research is needed to discern the etiology of this apparently common disease of captive polar bears.

    The possibility of using ordinary household table salt for dosimetry is suggested by its high sensitivity to ionising radiation, which generates a readout of optically stimulated luminescence (OSL). However, to exploit this finding for retrospective human dosimetry, it would be needed to find salt in close proximity to the exposed individual. Finding salty snacks frequently tucked into handbags, backpacks or pockets seemed to be a possibility; these items therefore became the test materials of the present study. The aluminium or cardboard packages used to exclude the moisture that makes crisps and nuts go soft and stale also helps to retain the induced OSL signal. Therefore, different snacks, either their salt component alone or mixed with the snack, are exposed to ionising radiation and then were assessed for their dosimetric properties. The results indicate the feasibility of using some salty snacks for dosimetry, with a minimum detectable dose as low as 0.2 mGy (authors)

    A retrospective study of 160 pediatric neuroradiological examinations was conducted to determine the efficacy and safety of two sedation regimens (figs. 1, 2). For CT purposes, 150 patients (fig. 3) were orally given monosodium trichlorethyl phosphate syrup (100 mg/kg, with repeat 50 mg/kg if necessary), and for cerebral angiography, 15 patients (fig. 4) were intramuscularly administered a modified D.P.T. cocktail (pentazocine, chlorpromadine, promethazine). Failure rate in the oral syrup group was 6%, and in the D.P.T. group 6.7%. Diagnostic-quality images were obtained in 99.3% and 100%, respectively, of the two groups. There were neither mortality nor significant complications (table 3). It was concluded that each method had proved acceptably safe and effective, and that measures can be taken to further decrease complications and sedation failures. (author)

    A retrospective multicenter study. Routine cervical spine surgeries are typically associated with low complication rates, but serious complications can occur. Intraoperative death is a very rare complication and there is no literature on its incidence. The purpose of this study was to determine the intraoperative mortality rates and associated risk factors in patients undergoing cervical spine surgery. Twenty-one surgical centers from the AOSpine North America Clinical Research Network participated in the study. Medical records of patients who received cervical spine surgery from January 1, 2005, to December 31, 2011, were reviewed to identify occurrence of intraoperative death. A total of 258 patients across 21 centers met the inclusion criteria. Most of the surgeries were done using the anterior approach (53.9%), followed by posterior (39.1%) and circumferential (7%). Average patient age was 57.1 ± 13.2 years, and there were more male patients (54.7% male and 45.3% female). There was no case of intraoperative death. Death during cervical spine surgery is a very rare complication. In our multicenter study, there was a 0% mortality rate. Using an adequate surgical approach for patient diagnosis and comorbidities may be the reason how the occurrence of this catastrophic adverse event was prevented in our patient population.

    Full Text Available Background. No consensus between guidelines exists regarding neuroimaging in first-episode psychosis. The purpose of this study is to assess anomalies found in structural neuroimaging exams (brain computed tomography (CT and magnetic resonance imaging (MRI in the initial medical work-up of patients presenting first-episode psychosis. Methods. The study subjects were 32 patients aged 18–48 years (mean age: 29.6 years, consecutively admitted with first-episode psychosis diagnosis. Socio-demographic and clinical data and neuroimaging exams (CT and MRI were retrospectively studied. Diagnostic assessments were made using the Operational Criteria Checklist +. Neuroimaging images (CT and MRI and respective reports were analysed by an experienced consultant psychiatrist. Results. None of the patients had abnormalities in neuroimaging exams responsible for psychotic symptoms. Thirty-seven percent of patients had incidental brain findings not causally related to the psychosis (brain atrophy, arachnoid cyst, asymmetric lateral ventricles, dilated lateral ventricles, plagiocephaly and falx cerebri calcification. No further medical referral was needed for any of these patients. No significant differences regarding gender, age, diagnosis, duration of untreated psychosis, in-stay and cannabis use were found between patients who had neuroimaging abnormalities versus those without. Discussion. This study suggests that structural neuroimaging exams reveal scarce abnormalities in young patients with first-episode psychosis. Structural neuroimaging is especially useful in first-episode psychosis patients with neurological symptoms, atypical clinical picture and old age.

    Full Text Available BackgroundThis paper discusses the treatment protocol for patients with frostbite.MethodsWe performed a retrospective analysis of a series of 17 patients with second- and higher-degree frostbite who had been treated at our medical institution between 2010 and 2012.ResultsOur clinical series of patients (n=17 included 13 men and four women, whose mean age was 42.4±11.6 years (range, 22-67 years. The sites of injury include the foot in six patients (35.3%, the hand in six patients (35.3% and the facial region in five patients (29.4%. Seven patients with second-degree frostbite were completely cured with only conservative treatment during a mean period of 12.7±3.3 days (range, 8-16 days. Of the five patients with third-degree frostbite, two underwent skin grafting following debridement, and the remaining three achieved a complete cure with conservative treatment during a mean period of 35±4.3 days (range, 29-39 days. Five patients with fourth-degree frostbite were treated with surgical procedures including amputation.ConclusionsWith the appropriate conservative management in the early stage of onset, surgeons should decide on surgery after waiting for a sufficient period of time until the demarcation of the wound. Continuous management of patients is also needed to achieve functional recovery after a complete cure has been achieved. This should also be accompanied by patient education for the avoidance of re-exposure to cold environments.

    Full Text Available Background/introductionEarly reports of stereotactic body radiation therapy (SBRT for pancreatic ductal adenocarcinoma (PDAC used single fraction, but eventually shifted to multifraction regimens. We conducted a single institution review of our patients treated with single- or multifraction SBRT to determine whether any outcome differences existed.Methods and materialsPatients treated with SBRT in any setting for PDAC at our facility were included, from 2004 to 2014. Overall survival (OS, local control (LC, regional control (RC, distant metastasis (DM, and late grade 3 or greater radiation toxicities from the time of SBRT were calculated using Kaplan–Meier estimation to either the date of last follow-up/death or local/regional/distant failure.ResultsWe identified 289 patients (291 lesions with pathologically confirmed PDAC.

    Purpose. - Surgery is the treatment of choice for localized uterine sarcomas. We conducted a retrospective study to define prognostic factors. Patients and methods. - We studied 111 cases of patients treated by adjuvant radiotherapy for uterine sarcoma in seven French centers. The median decline was 31 months. We conducted a univariate analysis to identify factors correlated with local recurrence. The statistically significant factors were studied in multivariate analysis by Cox model. Results. - The median dose of external beam radiotherapy was 45 Gy. Forty-three percent of patients had vaginal vault brachytherapy and 21 % chemotherapy. Only 6.3 % of patients had complications of acute grade III and 8.1 % of long-term sequelae of radiotherapy. The survival rate at 5 years was 74.6 %. They noted 12.6 % of isolated locoregional recurrences, against 29.7 % for distant recurrences, 80 % were pulmonary. Factors correlated with the risk of locoregional relapse were menopausal status (P = 0.045) and surgical margins suspicious or not healthy (P = 0.0095). The chemotherapy did not improve overall survival or disease free survival but the numbers were low. Conclusion. - The postoperative radiotherapy provides good local control in this disease. Brachytherapy is sometimes done, but it does not improve local control. Chemotherapy is not a standard localized stage but the rate of metastatic recurrence calls for the development of strategies involving systemic treatment with radiotherapy. (authors)

    Canine sterile nodular panniculitis (SNP) is an inflammatory disease of the panniculus that is typically managed with immunomodulatory or immunosuppressive treatments. It has been reported to be a cutaneous marker of an underlying systemic disease. To assess the presence or absence of concurrent systemic diseases associated with canine SNP and to document breed predispositions. Thirty nine dogs presented to a veterinary teaching hospital from 1990 to 2012 which met inclusion criteria. Inclusion in this retrospective study required a diagnosis of SNP via histopathological analysis and negative special stains for infectious organisms. Breed distributions of affected dogs were compared to all other dogs examined at this hospital during the study period. Correlations between the histological pattern of panniculitis and the histological presence of dermatitis, clinical presentation of lesions, dog breed and therapeutic outcomes were assessed. Australian shepherd dogs, Brittany spaniels, Dalmatians, Pomeranians and Chihuahuas were significantly over-represented, but correlations between inflammatory patterns of panniculitis and other histological and clinical factors were not identified. Based on the information available in medical records, 32 dogs (82.1%) had no concurrent systemic diseases identified. Four dogs had concurrent polyarthritis, which may be related to SNP through unknown mechanisms. This study identified several novel breed predilections for SNP; it failed to find any clear correlations with associated systemic diseases other than polyarthritis. The histological inflammatory pattern of SNP does not predict therapeutic outcome. © 2015 ESVD and ACVD.

    Objectives The objective of the study was to evaluate whether oral cobalamin supplementation can restore normocobal-aminaemia in cats with hypocobalaminaemia and clinical signs of gastrointestinal disease. Methods This was a retrospective study based on a computerised database search for client-owned cats treated at Evidensia Specialist Animal Hospital, Helsingborg, Sweden, during the period December 2013 to August 2016. Inclusion criteria were cats with clinical signs of chronic enteropathy, an initial serum cobalamin concentration ⩽250 pmol/l (reference interval 214-738 pmol/l) and oral treatment with cobalamin tablets. Results Twenty-five cats met the inclusion criteria. The cats were treated with 0.25 mg cyanocobalamin tablets once daily. Serum cobalamin concentration was rechecked 27-94 days after continuous oral cobalamin supplementation. All cats had serum cobalamin concentrations above the reference interval after oral cobalamin supplementation. Median (range) serum cobalamin concentration was 128 pmol/l (111-250 pmol/l) prior to treatment and 2701 pmol/l (738-16,359 pmol/l) after supplementation. This difference was statistically significant ( P cats with hypocobalaminaemia. Thus, oral cobalamin supplementation is a promising alternative to parenteral administration. Prospective comparative studies in cats being treated with parenteral vs oral cobalamin supplementation in a larger number of patients are warranted before oral supplementation can be recommended for routine use.

    OBJECTIVE: The purpose of this study was to examine the relationship among methadone maintenance treatment, perinatal outcomes, and neonatal abstinence syndrome. STUDY DESIGN: This was a retrospective cohort study of 61,030 singleton births at a large maternity hospital from 2000-2007. RESULTS: There were 618 (1%) women on methadone at delivery. Methadone-exposed women were more likely to be younger, to book late for antenatal care, and to be smokers. Methadone exposure was associated with an increased risk of very preterm birth <32 weeks of gestation (adjusted odds ratio [aOR], 2.47; 95% confidence interval [CI], 1.40-4.34), being small for gestational age <10th percentile (aOR, 3.27; 95% CI, 2.49-4.28), admission to the neonatal unit (aOR, 9.14; 95% CI, 7.21-11.57), and diagnosis of a major congenital anomaly (aOR, 1.94; 95% CI, 1.10-3.43). There was a dose-response relationship between methadone and neonatal abstinence syndrome. CONCLUSION: Methadone exposure is associated with an increased risk of adverse perinatal outcomes, even when known adverse sociodemographic factors have been accounted for. Methadone dose at delivery is 1 of the determinants of neonatal abstinence syndrome.

    Fournier's gangrene is a rapidly progressing necrotizing fascitis that affects the perineal and genital area. Mortality still remains high. The aim of this study was to evaluate the epidemiological progression and morbidity-mortality of Fournier's gangrene at our centre over the past 10 years. Retrospective study of 41 patients treated for Fournier's gangrene between 1998 and 2007. Variables studied included, demographic variables, aetiology, microbiology, surgical and antibiotic treatment, morbidity, and mortality. The mean age of the patients was 60, and 93% were male. The most common co-morbidity was diabetes (49%), followed by alcoholism (46%) and immunosuppression or neoplasia (34%). The origin was perianal in 66% of cases, followed by a urological origin (32%). The median time from the onset of symptoms to diagnosis was 3 days. Several surgical debridements were required in 49% of the patients, and the mortality rate was 29%. Most cases had positive cultures (93%), and in 76% more than one microorganism was isolated (enterobacteriaceae and anaerobic flora). In the bivariate analysis, antimicrobial treatment with carbapenems and the absence of systemic complications were associated with lower mortality. Fournier's gangrene continues to be a severe surgical emergency, with a high mortality rate. Early diagnosis and aggressive surgical and antibiotic therapy are necessary for adequate management.

    Sclerodermas are rare affections which can be located or generalized. Localized form is the most frequent. The purpose of this study was to describe epidemiologic, clinics, biological, immunological, therapeutic, evolutionary characteristics of the localized scleroderma through a personal series and the data of the literature. We have performed a retrospective study on all patients followed in the department of dermatology of the Hospital Charles Nicole during 14 years period. Our study was about 92 cases of localized scleroderma (73 were females and 19 males). The mean age was 35 years (between 2 and 72 years). The majority of localised sclerodermas (66.2% of the cases) appeared before 40 years with a maximum of frequency between 10 and 30 years (41.6%). Only 11.9% of the cases were observed before 10 years. They were 51 cases (55%) of morphea, 35 cases (38%) of scleroderma in bands including 32 linear scleroderma and 3 scleroderma en coup de sabre, 5 cases (5.5%) of generalized morphea and 1 case (0.15%) of deep morphea. Average therapeutic was specified among 63 patients (87%), and the evolution could be appreciated among 45 patients. The epidemiologic data observed in our series are comparable with those reported in the literature. Therapeutic difficulties and risks of functional after-effects, particular in scleroderma in bands, remain the principal concern for all the authors.

    PurposeThis study is the first to present the outcomes of the Straub Aspirex device for the salvage of occluded renal dialysis access fistulae.Materials and MethodsThis is a retrospective study, using data from the Renal Unit and Radiology Department database. It included all the patients between 2010 and 2014 who underwent percutaneous mechanical thrombectomy (PMT) treated by JD. Aspirex is an over-the-wire, 6–10 French catheter within which is a rapidly rotating helix which draws thrombus into a window near the tip which it then macerates and removes. Access survival was assessed using the Kaplan–Meier method, and multi-variant analysis was performed using the Cox proportional hazards model. Significance was considered if p < 0.05.ResultsA total of 27 procedures were performed for 19 patients. 13 had autologous arterio-venous fistulae, and 14 had synthetic (PTFE) arterio-venous grafts. 15 were males, 4 females. 100 % of the patients successfully had a channel of thrombus removed. This resulted in an 81.5 % initial clinical success, with primary patency rates of 53.6, 44.3 and 33 % by days 30, 90 and 480, respectively, without significant difference of any analysed covariates. No major complication (pulmonary embolus, paradoxical cerebral infarction, limb ischaemia or significant haemorrhage) occurred.ConclusionAspirex has rates of patency and complication similar to other PMT devices. No covariant studied affected outcome.

    Full Text Available AIM: To analyze childhood glaucoma regarding its demographics, presentations, different causes and surgical modalities used among patients in Dakahelia and to apply the Childhood Glaucoma Research Network (CGRN classification retrospectively to evaluate its convenience. METHODS: A retrospective study in which the medical files of all glaucoma patients <16 years old presented to Mansoura Ophthalmic Center, Mansoura University from 2014 to 2017, were retrieved and analyzed. Collected data included: age, gender, laterality, visual acuity (VA, refraction, intraocular pressure (IOP, corneal diameter, cup-disc ratio, types and number of surgeries and antiglaucomatous drugs (AGD at the first and last visit. Prevalence of different subtypes was calculated and means of clinical features were compared. RESULTS: A total of 305 eyes of 207 patients were included classified into 6 groups: primary congenital glaucoma (PCG, juvenile open angle glaucoma (JOAG, glaucoma associated with systemic disease, glaucoma associated with ocular anomalies, acquired glaucoma and glaucoma following cataract surgery. PCG was the predominant type (55.1% followed by acquired glaucoma (29.5%. Males represented 63.8% of the whole studied patients. Glaucoma associated with ocular anomaly group showed the youngest age at diagnosis (21.9±30.0mo. The shortest corneal diameter was recorded in post cataract group (10.4±0.5 mm. Highest cup-disc ratio was found in the PCG group (P<0.0005. Glaucoma associated with systemic disease presented with the highest baseline IOP (34.5±5.0 mm Hg. All the cases with PCG were treated surgically with 21.8% required more than one surgery. The majority of the patients (74.2% in the acquired group were treated medically. Combined trabeculotomy-trabeculectomy was the most frequent operation done, accounting for 34.5% of all primary surgeries. Ahmed valve implantation comprised 87% of the secondary surgeries. Acquired glaucoma group had the highest

    Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported with the association of torsion in surgical specimens, and the published data remain scant on the association of torsion with testicular tumors. By retrospective medical record review, we identified 32 patients who had been diagnosed with testicular torsion, 20 of whom had undergone orchiectomy. Of these 20 patients, 2 were diagnosed with a malignancy. Our study, the largest case series to date, has shown an association between testicular torsion and testicular cancer of 6.4%. Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported in association with torsion in surgical specimens. However, the published data remain scant on the association between torsion and the presence of testicular tumors. The present retrospective study explored the association between torsion and testicular cancer in patients with testicular torsion undergoing orchiectomy during scrotal exploration. A medical record review was performed of patients who had had a diagnosis of testicular torsion from January 2003 to February 2015. The clinicopathologic characteristics of the patients were recorded. A total of 32 patients were identified. Their mean age was 21.1 years (range, 7-39 years). All the patients had unilateral testicular torsion, which affected the left side in 17 and the right side in 15. Manual detorsion was successful in 6 patients, and 26 patients underwent emergency surgery with testicular detorsion (6 fixation surgery and 20 orchiectomy). The type of incision was scrotal in 6, inguinal in 10, and unspecified in 4. Pathologic examination of the orchiectomy specimens showed malignancy in 2 cases (seminoma and malign mixed germ cell tumor). To the best of our knowledge, the present single-center case series is the largest case series to date of

    Full Text Available Aims and Objectives: To study the clinical presentations of gestational trophoblastic neoplasia and its response to chemotherapy. Materials and Methods: This is a retrospective study of 28 women of gestational trophoblastic neoplasia evaluated over a period of 6 years from January 2004 to December 2009. Patients were evaluated on the basis of their age, number of deliveries, history of abortion or molar pregnancy, and the treatment received. All patients were scored on the basis of WHO scoring system. Patients with low risk (score /=7 received multiple agent chemotherapy with EMACO regimen. After completion of chemotherapy patients were followed for a minimum of 2 years. The response to treatment was evaluated during follow-up by clinical examination, beta hCG levels and imaging as and when required. Results: Out of 28 women only 27 could be evaluated, because 1 patient was lost to follow-up. Out of 27 patients, 18 patients (66.67% achieved complete remission with the first-line chemotherapy and additional 25.92% (7/27 achieved complete remission with second line chemotherapy resulting in complete remission of 92.5% (25/27. Conclusion: Gestational trophoblastic neoplasia is curable if patient is properly evaluated and scored. It shows good response to chemotherapy.

    The aim of this study is to investigate the safety and efficacy of castor oil to induce labour. A retrospective observational case control study was conducted over five years. Castor oil was proposed to women referred to the Birth Centre (Castor Oil group (COG)). They were compared to women who chose to be followed by the traditional doctor-led unit (control group (CG)). Castor oil was administered in a 60 ml single dose in 200 ml of warm water. Inclusion criteria were gestational age between 40 and 41 weeks plus premature rupture of membranes between 12 and 18 hours or amniotic fluid index ≤4 or Bishop Score of ≤4 or absence of spontaneous labour over 41 + 4 weeks. Pharmacological induction of labour was required for 18 women in the COG (45%) and 36 in the CG (90%) (p oil showed a higher incidence of vaginal delivery, whereas the incidence of caesarean section was lower in the COG, but no statistical significance was reached. The use of castor oil is related to a higher probability of labour initiation within 24 hours. Castor oil can be considered a safe non-pharmacological method for labour induction.

    Full Text Available Background. The aim of this study was to assess the association between herbal medication and OHSS. Methods. This retrospective cohort study was conducted with 101 polycystic ovary syndrome patients. 66 patients took conventional pharmacological medications and 35 took herbal medications. Data were analyzed by statistical test including Fisher’s Exact and binominal logistic regression. P<0.05 was considered significant. Results. Of the 101 females, 53 were married and 48 were single. There was no significant association between the groups in marriage. No significant association was found in mean age between the two groups (23.9 ± 5.8 years in the control group versus 26.3 ± 6.7 years in the case group. There was a significant difference between the two groups .After adding the dependent (OHSS prevalence and independent (marriage and group variables into the model, the Hosmer-Lemeshow test showed suitability. Variances analyzed with this model ranged between 29.4% and 40.7%. Conclusion. The indiscriminate use of herbs is correlated with OHSS. Because patients increasingly consume herbs, they should be aware of potential side effects. However, appropriate dosages of herbs could be obtained for use instead of conventional treatments, which often have side effects.

    The aim of the study was to compare historical features, physical examination findings, and testicular color Doppler ultrasound in pediatric patients with epididymitis compared to testicular torsion and torsion of the appendix testes. A retrospective review of the medical records of 66 boys presenting with clinical aspects of acute scrotum over a 3-year period was performed. Sixty-six patients were included in the study (29 with epididymitis, 8 with testicular torsion and 12 with torsion of the appendix testis, 4 with scrotal abscesses, 5 with scrotal swelling, and 1 with inflamed epididymal cyst). The duration of symptoms ranged from 6 h to 4 days with a peak on the second day. Urine cultures and viral testes were negative in all patients. Color Doppler ultrasound was diagnostic for epididymitis in 28 patients (96.6%). Systemic intravenous antibiotics were given in all 29 patients with epididymitis. No patient showed signs of testicular atrophy in the follow-up. The increasing incidence of epididymitis should question the policy of routine exploration of the acute scrotum in children. The history and physical examination cannot reliably identify those boys who can be managed conservatively. Color Doppler ultrasound is a useful adjunct in the evaluation of the acute scrotum when physical findings are equivocal but it can also be misleading.

    Aim To determine the prevalence of various malignant oral lesions in the UAE and correlate cases of squamous cell carcinomas with age, gender, site, grade, clinical presentations at the time of diagnosis, and the prevalence of neck metastasis. Materials and methods A multicenter, retrospective study was conducted at four major hospitals in the UAE. The study was based on histopathology reports of biopsies of oral tissues. Results Of the 992 oral biopsy reports retrieved, 147 cases of malignant tumors were found which accounted for 14.9% of the total biopsies. Fifteen different types of malignant lesions were diagnosed, of which oral squamous cell carcinoma (OSCC) was the most prevalent and made up 11.4% of the overall oral biopsies retrieved. The commonest presentation of cancer was ulceration (31.17%), followed by lumps and white lesions. The most common site where the lesions were diagnosed was the tongue (51.9%), followed by the cheeks and lips. OSCC accounted for 77% of all malignancies reported. Neck dissections were conducted in only 20.8% of all OSCC cases diagnosed at Mafraq and Tawam hospitals, of which 43.75% showed evidence of neck metastasis. Conclusion Oral cancer is not an uncommon disease in the UAE. This may mandate more awareness campaigning, including screening procedures for early detection of cancerous lesions and other potentially malignant oral diseases. Elective neck dissections to detect lymph node metastasis should be more routinely performed, in particular for tongue carcinomas because of the early neck involvement potential. PMID:23985381

    Alveolar ridge keratosis (ARK) is a distinct, benign clinicopathological entity, characterized by a hyperkeratotic plaque or patch that occurs on the alveolar edentulous ridge or on the retromolar trigone, considered to be caused by chronic frictional trauma. The aim of this retrospective study is to present the clinicopathological features of 23 consecutive cases of ARK. The 23 biopsy samples of ARK were selected and pathological features were revised (keratosis, acanthosis, surface architecture, and inflammation). Factors such as the patient's gender, age, anatomical location, tobacco and alcohol use were analyzed. Sixteen out of the 23 cases studied were men and 7 women with a mean age of 55.05 (age ranged from 17 to 88 years). Thirteen cases had a history of tobacco habit, amongst whom, 4 also presented alcohol consumption. All the cases presented only unilateral lesions. Nineteen cases involved the retromolar trigone while 4 cases involved edentulous alveolar ridges. When observed microscopically, the lesions were mainly characterized by moderate to important hyperorthokeratosis. Inflammation was scanty or absent. In four of the cases, the presence of melanin pigment in the superficial corium or in the cytoplasm of macrophages was detected. None of the cases showed any features of dysplasia. Our results reveal that ARK is a benign lesion. However, the high prevalence of smokers amongst the patients might suggest that some potentially malignant disorders such as tobacco associated leukoplakia may clinically mimic ARK.

    Bronchiectasis is characterized by abnormal, permanent and irreversible dilatation of the bronchi, usually responsible for daily symptoms and frequent respiratory complications. Many causes have been identified, but only limited data are available concerning the association between bronchiectasis and renal transplantation. We conducted a retrospective multicenter study of cases of bronchiectasis diagnosed after renal transplantation in 14 renal transplantation departments (French SPIESSER group). Demographic, clinical, laboratory and CT scan data were collected. Forty-six patients were included (mean age 58.2 years, 52.2 % men). Autosomal dominant polycystic kidney disease (32.6 %) was the main underlying renal disease. Chronic cough and sputum (50.0 %) were the major symptoms leading to chest CT scan. Mean duration of symptoms before diagnosis was 1.5 years [0-12.1 years]. Microorganisms were identified in 22 patients, predominantly Haemophilus influenzae. Hypogammaglobulinemia was observed in 46.9 % patients. Bronchiectasis was usually extensive (84.8 %). The total bronchiectasis score was 7.4 ± 5.5 with a significant gradient from apex to bases. Many patients remained symptomatic (43.5 %) and/or presented recurrent respiratory tract infections (37.0 %) during follow-up. Six deaths (13 %) occurred during follow-up, but none were attributable to bronchiectasis. These results highlight that the diagnosis of bronchiectasis should be considered in patients with de novo respiratory symptoms after renal transplantation. Further studies are needed to more clearly understand the mechanisms underlying bronchiectasis in this setting.

    Full Text Available Background: In recent decades, there has been a dramatic increase in the prevalence of multiple pregnancies. An important reason is the increased use of assisted reproductive techniques for conception. Despite the advances in prenatal care, maternal and neonatal morbidity and mortality caused by multiple pregnancies are still high. Aim: This study aimed to evaluate the fetomaternal complications in higher order multiple pregnancies. Design: The design is a retrospective study. Setting: Triplet and quadruplet pregnancies were investigated in this study. Methods: This study investigated the outcome of triplet and quadruplet pregnancies born alive at the Mahdiyeh hospital, Tehran, Iran from 2006 to 2015. Results: In this study, 111 triplet pregnancies and 24 quadruplet pregnancies were studied, 80% of which resulted from assisted reproductive technology. The average age of pregnancy termination was 31 weeks, the average weight of the first to third neonates was 1400 g and the average weight of the fourth neonate was 700 g. The most common reason for early termination of pregnancy was preterm labor, the most maternal complication was uterine atony and the most common neonatal complication was pre-maturity and then respiratory distress syndrome (RDS. The mean age of mother in triplets’ deliveries was significantly lower than in the quadruplets. The average weight of the first to third neonates, the average of 1st and 5th minutes Apgar score of the first neonates and the average gestational age of termination for the first and second neonates in triplets was significantly higher than in the quadruplets. Hospitalization due to preterm labor in quadruplets’ delivery was significantly higher than in triplets. Conclusion: Higher order multiple pregnancies are associated with higher maternal and neonatal complications. Mothers with such pregnancies needs more care in the prenatal period, during labor and in the postpartum period, and also their

    Full Text Available Background/Aims: Open reduction and internal fixation (ORIF is a standard surgical procedure in jaw trauma and in orthognathic surgery. Insertion of screws is a significant risk for accidental tooth root injury with varying outcomes. Contrary evidences are found in literature due to a variety of study designs. This study was undertaken to address the lacunae and possibly estimate the difference in occurrence of tooth damage during or after ORIF between trauma and planned osteotomies. Materials and Methods: In this retrospective study, the data of ORIF in either trauma or orthognathic surgery fulfilling inclusion and exclusion criteria were collected and analyzed. Results: There were 1632 patients fulfilling the inclusion and exclusion criteria and formed the study group, of which 663 were in orthognathic surgery, of whom 210 had bimaxillary orthognathic surgery. In the trauma group, 358 patients had fractures involving both jaws whereas 272 had maxilla alone and 339 had mandibular fractures alone. On comparing the outcome, of the 9073 screws studied, 93.40% were not involved in any contact with the teeth, 6.3% were in category of potential hits (near apices or the root surfaces, and only 0.28% had evidence of root damage with the screws. It is observed that molar and premolar had a significant difference in terms of the type of surgery (P ≤ 0.05 whereas canine (P = 0.75 and incisor (P = 0.67 showed no statistical difference. Conclusion: ORIF when used as mentioned is a safe way for the management of fractures. The incidence of root injury is not uncommon but can be avoided with careful planning and execution.

    There are minimal data on the use of electroconvulsive therapy (ECT) in adolescents from India. The present study aimed to evaluate the clinical profile and effectiveness of ECT in adolescents (aged 13-18 years). A retrospective chart review was carried out to identify adolescents (aged 13-18 years) who had received ECT during the period 1999-2011. During the study period, 39 such patients received ECT; complete records of 25 patients were available. Details regarding their sociodemographic, clinical, and treatment data were extracted from these records for the present study. During the study period, 658 patients received ECT, of which 39 were aged 18 or younger (5.9%). Schizophrenia (n = 14; 56%) was the commonest diagnosis for which ECT was used in adolescents, followed by depression (n = 3; 12%). Catatonic symptoms (n = 17; 68%) were the most common symptoms among these subjects. Electroconvulsive therapy was considered as a treatment of choice taking the clinical picture account in about three fourths of the patients (n = 19; 76%). The mean (SD) numbers of ECTs administered per patient were 10.1 (4.87) (range, 2-21). The mean (SD) response rate to ECT was 76% (23.3%) (range, 31%-100%). Response rates according to diagnosis were the following: 76.3% for schizophrenia, 87.2% for depression, 81.8% for psychosis (not otherwise specified), and 77.7% for acute and transient psychosis. Response rate in patients with catatonia was 91.6%. Prolonged seizures, nausea and vomiting, and headache were reported in 2 cases each. Electroconvulsive therapy is used less frequently in children and adolescents compared to the older patients. This study shows that ECT is effective in the treatment of severe psychiatric disorders in adolescents and is associated with the same frequency of adverse effects as the adults.

    Dental implant insertion for oral rehabilitation is a worldwide procedure for healthy and medically compromised patients. The impact of systemic disease risks on the outcome of implant therapy is unclear, since there are few if any published randomized controlled trials (RCTs). The objective of this study is to investigate the rate of complications and failures following dental implantation in medically compromised patients in order to elucidate risk factors and prevent them. A retrospective cohort study was conducted from patient files treated with dental implantation between the years 2008-2014. The study group consisted of medically complex patients while the control group consisted of healthy patients. Preoperative, intraoperative, and post operative clinical details were retrieved from patients' files. The survival rate and the success rate of the dental implants were evaluated clinically and radiographically. A total of 204 patients (1003 dental implants) were included in the research, in the study group, 93 patients with 528 dental implants and in the control group, 111 patients with 475 dental implants. No significant differences were found between the groups regarding implant failures or complications. The failure rate of dental implants among the patients was 11.8 % in the study group and 16.2 % in the control group (P = 0.04). It was found that patients with a higher number of implants (mean 6.8) had failures compared with patients with a lower number of implants (mean 4.2) regardless of their health status (P dental implantation in medically complex patients and in healthy patients. Medically complex patients can undergo dental implantation. There are similar rates of complications and failures of dental implants in medically complex patients and in healthy patients.

    Full Text Available BACKGROUND Electroconvulsive Therapy (ECT among adolescent psychiatric patient is rarely used and studies in this regard are also rare, while its need is of great importance. Aim of this study was to study the prevalence of ECT in common psychiatric illnesses among adolescent age group, where it is indicated and outcome of ECT in those psychiatric patients. MATERIALS AND METHODS All data were collected retrospectively from the chart review for those adolescents aged between 12 to 18 years who received ECT during the period of 2008 - 2012. During the study period a total of 554 patients received ECT, among whom 104 were adolescents. RESULTS Adolescent patients were 18.77% in the whole ECT sample; the average age of the adolescents was 16.33 years and number of patients were more with older age. Among all the patients, 48.08% had positive family history of mental illness and 81.73% were from lower Socioeconomic Class. The use of ECT was more with schizophrenia (n= 63, 60.57% and acute and transient psychotic disorder (n= 30, 28.85%. The most common indication was agitation and aggression (n= 29, 27.88% followed by poor medication response (n= 19, 18.27%. Good response is found in most of the cases (n= 88, 84.62%, only a few percentage of cases showed minor and transient adverse event. CONCLUSION The result of our study suggests that prevalence of ECT among adolescent psychiatric patients is quite high and ECT is a safe and effective method of treatment in the adolescent psychiatric patients, especially those patients who are severely ill and poorly responding to medication.

    Full Text Available This retrospective study determined the frequency of orthopedic diseases in horses. It was possible to establish 141 specific orthopedic diagnoses in 1955 horses with lameness. In 14.58 % horses, multiple pathologic orthopedic changes were determined. In 61.84 % cases, the pathologic changes were present on the thoracic limb, 28,86 % on the pelvic limb and other parts of the oganism (neck, spine, muscles in 9.29 % cases. Pathologic changes on the tendons, ligaments, tendon sheats, bursae and muscles were determined in 31.51 % cases. Diseases of the hoof were present in 25.82 % cases. According to our investigation the most frequent orthopedic diseases are: podarthritis (acute, chronic, septic (5.04 %, navicular disease (4.69 %, tendinitis m. flexor digitalis superfacialis (4.51 %, kissing spine syndrom (4.30 % periarthritis et osteoarthrosis tarsi (3.30 %, distal metacarpal/metatarzophalengeal tendovaginitis (3.30 % and high suspensory ligament desmitis (3.12 %. Most frequent fractures were diagnosed on the metacarpal/metatarsal bone II and IV (2.56 %. Osteochondrossis dissecans was most frequently determined in the tarsocrural (1.26 % and the metacarpophalengeal joint (1.56 %.

    Waterpipe smoking may increasingly account for unintentional carbon monoxide poisoning, a serious health hazard with high morbidity and mortality. We aimed at identifying waterpipe smoking as a cause for carbon monoxide poisoning in a large critical care database of a specialty care referral center. This retrospective cohort study included patients with a history of exposure to waterpipe smoking and carbon monoxide blood gas levels >10% or presence of clinical symptoms compatible with CO poisoning admitted between January 2013 and December 2016. Patients' initial symptoms and carbon monoxide blood levels were retrieved from records and neurologic status was assessed before and after hyperbaric oxygen treatment. Sixty-one subjects with carbon monoxide poisoning were included [41 males, 20 females; mean age 23 (SD ± 6) years; range 13-45] with an initial mean carboxyhemoglobin of 26.93% (SD ± 9.72). Most common symptoms included syncope, dizziness, headache, and nausea; 75% had temporary syncope. Symptoms were not closely associated with blood COHb levels. CO poisoning after waterpipe smoking may present in young adults with a wide variability of symptoms from none to unconsciousness. Therefore diagnosis should be suspected even in the absence of symptoms.

    Rocky Mountain spotted fever (RMSF), a lethal tick-borne illness, is prevalent in the south central United States. Children younger than 10 years old have the greatest risk of fatal outcome from RMSF. The objective of the current study was to review pediatric cases of RMSF seen in the dermatology consult service and to evaluate dermatology's role in the diagnosis and management of this disease. A retrospective review was performed of inpatient dermatology consultations at a tertiary care center in North Carolina from 2001 to 2011. Data collected included patient demographic characteristics, symptoms, pre- and postconsultation diagnoses, diagnostic procedures, length of hospital stay, and outcome. A total of 3,912 consultations were conducted in the dermatology service over 10 years. Six patients with RMSF, ranging in age from 22 months to 10 years (mean 5.1 years), were evaluated during April, May, and June. All preconsultation diagnoses included RMSF in the differential diagnosis. All patients underwent skin biopsies, and a culture was obtained in one case. Fifty percent of patients died within 4 days of hospitalization. Variables associated with mortality from RMSF are delayed diagnosis and initiation of antirickettsial therapy. Physicians should consider RMSF in children presenting with fever and rash during the summer months. Dermatology consultation is useful in evaluating patients with suspicious clinical features of RMSF with skin findings. © 2016 Wiley Periodicals, Inc.

    A retrospective study was undertaken in 1990 of 188 patients with the diagnosis of non small cell carcinoma of the lung referred to the Department of Radiation Oncology in 1984. Most patients (178 out of 188) received a course of radiotherapy. This was definitive in 23, palliative in 148 (primary site in 113, metastases in 16, primary plus metastases in 19) and postoperative in 7. This report is a 5 year follow-up of the 171 patients treated by radiation alone, to assess factors that influence survival. Palliative intent of treatment and poorer performance status were related significantly to increasing stage of disease. The effects of palliative treatment were recorded in 79 cases: in 71 there was a reduction in symptoms. The median survival from diagnosis was 8 months. Using univariate and multi-variate analyses, significant and independent prognostic factors for improved survival were good performance status, absence of systemic symptoms, lower tumour stage and curative intent of treatment (higher radiation dose). However the 5-year survival was only 2%. Long-term survival was associated predominantly with early stage disease but not with the type or intent of treatment. Age, sex, histology and apical site did not influence survival. These results are comparable to those found in the literature and emphasize the need to select patients carefully for either palliative or aggressive treatment. 29 refs., 4 tabs., 3 figs

    Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

    Our objective was to investigate whether pulmonary tuberculosis (PTB) can be predicted from features of a targeted medical history and basic laboratory investigations in immigrants. A retrospective cohort of 391 foreign-born adults referred to the Edmonton Tuberculosis Clinic (Edmonton, AB, Canada) was studied using multiple logistic regression analysis to predict PTB. Seven characteristics of disease were used as explanatory variables. Cross-validation assessed performance. Each predictor was tested on two outcomes: "culture-positive" and "smear-positive". Receiver operating characteristic (ROC) curves were generated and the area under the ROC curve (AUC) was quantified. Symptoms, subacute duration of symptoms, risk factors for reactivation of latent TB infection and anaemia were all associated with a positive culture (adjusted OR 1.79, 2.24, 1.72 and 2.28, respectively; p<0.05). Symptoms, inappropriate prescription of broad-spectrum antibiotics and a "typical" chest radiograph were associated with smear-positive PTB (adjusted OR 2.91, 1.55 and 12.34, respectively; p<0.05). ROC curve analysis was used to test e ach model, yielding AUC=0.91 for the outcome "culture-positive" disease and AUC=0.94 for the outcome "smear-positive" disease. PTB among the foreign-born can be predicted from a targeted medical history and basic laboratory investigations, raising the threshold of suspicion in settings where the disease is relatively rare.

    The objective of this study was to examine job separations from supported employment (SE). The aim was to identify the types and nature of separations and precipitating events leading to the separation. A retrospective chart review methodology was utilized. The study was conducted in a metropolitan area in the Southeast United States by a university-based SE program. Participants were 47 SE clients who had been placed into and separated from 67 jobs. Using a coding form, information regarding the type of separation and issues that preceded the separation were recorded. Data were aggregated using descriptive statistics. The largest number of separations was due to termination, followed by resignation and mutual consent of the employer and employee. The mean number of issues leading to the separation was 2.2, ranging from one to five. Only eight positive issues were found (compared to 116 negative and 20 neutral), the most prevalent being entry into an educational or training program. Common negative issues included poor work performance, attendance and punctuality problems, conflicts with the supervisor, and social and behavioral issues. The findings of this study illustrate the need to address job retention issues during the job development process, finding the most appropriate person-job fit and workplace culture for each client. The findings also support the need for vigilant and regular communication between the SE program and employers to intervene quickly when problems arise. Separation from Supported Employment (SE) SE is an evidence-based employment practice that has been shown effective across multiple disability groups. Studying job separations can provide valuable information for improving service. Locating the best person-job fit, as well as frequent contract with employers, can help prevent unnecessary job loss.

    The immune and inflammatory pathways involved in psoriasis could favor the development of atherosclerosis, consequently increasing mortality. The objectives of this study were: 1) to assess the mortality of a population with psoriasis compared to a control group, and 2) to assess the prevalence of cardiovascular risk factors. A retrospective cohort was analyzed from a secondary database (electronic medical record). All patients with a diagnosis of psoriasis at 1-01-2010 were included in the study and compared to a control group of the same health system, selected randomly (1:1). Subjects with a history of cardiovascular disease were excluded from the study. A survival analysis was performed considering death from any cause as an event. Follow-up was extended until 30-06-2015. We included 1,481 subjects with psoriasis and 1,500 controls. Prevalence of cardiovascular risk factors was higher in the group with psoriasis. The average follow-up time was 4.6±1.7 years. Mortality was higher in psoriasis patients compared to controls (15.1 vs. 9.6 events per 1,000 person-year, PPsoriasis was seen to be significantly associated with increased mortality rates compared to the control group in the univariate analysis (HR 1.58, 95% CI 1.16-2.15, P=.004) and after adjusting for cardiovascular risk factors (HR 1.48, 95% CI 1.08-2.3, P=.014). In this population, patients with psoriasis showed a higher prevalence for the onset of cardiovascular risk factors as well as higher mortality rates during follow-up.

    Totally implantable port systems are generally recommended for prolonged central venous access in diverse settings, but their risk of complications remains unclear for patients with advanced cancer. The aim of this study was to assess the risk of port system failure in patients with advanced cancer. We conducted a retrospective cohort study in a comprehensive cancer centre. A detailed chart review was conducted among 566 patients with 573 ports inserted during January-June, 2009 (average 345.3 catheter-days). Cox regression analysis was applied to evaluate factors during insertion and early maintenance that could lead to premature removal of the port systems due to infection or occlusion. Port system-related infection was significantly associated with receiving palliative care immediately after implantation (hazard ratio, HR = 7.3, 95% confidence interval, 95% CI = 1.2-46.0), after adjusting for probable confounders. Primary cancer site also impacted the occurrence of device-related infection. Receiving oncologic/palliative care (HR = 3.0, P = 0.064), advanced cancer stage (HR = 6.5, P = 0.077) and body surface area above 1.71 m(2) (HR = 3.4, P = 0.029) increased the risk of port system occlusion. Our study indicates that totally implantable port systems yield a higher risk of complications in terminally ill patients. Further investigation should be carefully conducted to compare outcomes of various central venous access devices in patients with advanced cancer and to develop preventive strategies against catheter failure.

    The genesis of the NATO Advanced Study Institute (ASI) upon which this volume is based, occurred during the summer of 1986 when we came to the realization that there had been significant progress during the early 1980's in the field of superconducting electronics and in applications of this technology. Despite this progress, there was a perception among many engineers and scientists that, with the possible exception of a limited number of esoteric fundamental studies and applications (e.g., the Josephson voltage standard or the SQUID magnetometer), there was no significant future for electronic systems incorporating superconducting elements. One of the major reasons for this perception was the aversion to handling liquid helium or including a closed-cycle helium liquefier. In addition, many critics felt that IBM's cancellation of its superconducting computer project in 1983 was "proof" that superconductors could not possibly compete with semiconductors in high-speed signal processing.

    This retrospective study focused on the frequency of tooth loss due to periodontal abscess among 42 patients who were treated by a single clinician over a 5- to 29-year period. A total of 114 patients were selected from the active periodontal recall schedule of a single periodontist at The University of Iowa College of Dentistry. The criteria for inclusion in the study included having a history of moderate to advanced periodontitis, being on 3 to 6 month recall periodontal maintenance care, and completion of active periodontal therapy prior to October 1987. Other parameters evaluated were age; gender; number of teeth present and missing at the initial, reevaluation, and last periodontal recall visit; initial periodontal prognosis; furcation involvement; non-surgical and surgical periodontal therapy; and reasons for tooth loss. Patients were grouped according to the number of teeth lost following active periodontal treatment into well-maintained (0 to 3), downhill (4 to 9), and extreme downhill (10 to 23) groups. Forty-two of the 114 patients were identified as having one or more periodontal abscesses. A total of 109 teeth were affected by periodontal abscess of which 49 (45%) teeth were lost and 60 (55%) were successfully maintained over an average of 12.5 years (5 to 29 years). More furcated teeth were lost than nonfurcated teeth and teeth given a hopeless prognosis were lost more consistently than those given a questionable prognosis in all groups. The frequency of periodontal abscess and tooth loss per patient was greater in the downhill and extreme downhill response groups than the well-maintained group. This suggests that teeth with a history of periodontal abscess can be treated and maintained for several years.

    This study aimed to determine the prevalence rate of knee osteoarthritis (OA) and the risk factors for OA in hospitalized elderly patients. We conducted this retrospective study in elderly patients (aged 65 years and older) who were hospitalized in the Geriatric Ward of General Hospital of Guangzhou Military Command of the People's Liberation Army between January 2011 and June 2013, including general condition, present history, past history, physical examination, X-ray results, and disease diagnosis. The prevalence, awareness, and treatment rates of knee OA in hospitalized elderly patients were calculated. Risk factors were computed using multiple logistic regression analysis. Of a total of 267 (17.4%) hospitalized elderly patients diagnosed with knee OA, the prevalence rate of OA was 9.95% in males and 37.76% in females. The rate of awareness among those with OA was 51.68%; the rate of treatment was 83.33%; and the rate of control was 77.39%. The medical expenses for both females (1143±315 yuan month-1) and males (1192±357 yuan month-1) in knee OA patients are higher than that of the non-knee OA group (989±274 yuan month-1, 1038±295 yuan month-1). The risk factors for knee OA include gender (OR=2.448), age (OR=1.124), transportation mode (OR= 8.972), exercise (OR=7.374), bowel evacuation position (OR=5.767), family history of knee OA (OR=2.195), and body mass index (OR=2.469). The prevalence of knee OA is unexpectedly high in hospitalized elderly patients, and the rates of awareness and treatment are less than desirable. Prevention and control measures should be taken in patients with concomitant risk factors.

    Full Text Available Cattle and poultry enterprises are among the major contributors to food security and socioeconomic empowerment of households in Uganda. However, various diseases constrain their productivity. A two-year retrospective study between April 2012 and March 2014 was conducted using records for cattle and poultry diseases diagnosed at the Central Diagnostic Laboratory (CDL to determine prevalent diseases in Uganda. The laboratory received 836 samples from poultry (36.3% and cattle (63.7%. Of the 836 samples, 47.5% had a definitive diagnosis of disease causation. Most of the cattle and poultry diseases diagnosed were protozoan diseases (39.3% followed by bacterial (21.4%, viral (17.1%, helminthiasis (11.1%, nutritional diseases (4% and others (7.1%. For poultry, viral diseases (29.5% and protozoan diseases (27.1% especially newcastle disease (44.3% and coccidiosis (100% respectively, were the most diagnosed. While for cattle, hemo-protozoan parasites (52.1% were the most prevalent, of which 92.9% were east coast fever infection. Bacterial infection (20.5% in cattle were the second most diagnosed diseases and mastitis was the most diagnosed (46.2%. In summary, coccidioisis, collibacillosis, newcastle disease, gumboro disease, and avian helminthiasis were the most prevalent poultry diseases while in cattle, east coast fever, helminthiasis, mastitis, brucellosis and rabies were the most frequently diagnosed diseases. This study has identified the major diseases that hinder poultry and cattle production in Uganda. The data generated by CDL could be used for surveillance, monitoring and designing strategic interventions for control of poultry and cattle diseases in Uganda.

    To consider the effectiveness of early treatment using one mixed-dentition approach to the correction of moderate and severe Class II malocclusions. Three groups of Class II subjects were included in this retrospective study: an early treatment (EarlyTx) group that first presented at age 7 to 9.5 years (n = 54), a late treatment (LateTx) group whose first orthodontic visit occurred between ages 12 and 15 (n = 58), and an untreated Class II (UnTx) group to assess the pretreatment comparability of the two treated groups (n = 51). Thirteen conventional cephalometric measurements were reported for each group and Class II molar severity was measured on the study casts of the EarlyTx and LateTx groups. Successful Class II correction was observed in approximately three quarters of both the EarlyTx group and the LateTx group at the end of treatment. EarlyTx patients had fewer permanent teeth extracted than did the LateTx patients (5.6% vs 37.9%, P < .001) and spent less time in full-bonded appliance therapy in the permanent dentition than did LateTx patients (1.7 ± 0.8 vs 2.6 ± 0.7years, P < .001). When supervision time is included, the EarlyTx group had longer total treatment time and averaged more visits than did the LateTx group (53.1 ± 18. 8 vs 33.7 ± 8.3, P < .0001). Fifty-five percent of the LateTx extraction cases involved removal of the maxillary first premolars only and were finished in a Class II molar relationship. EarlyTx comprehensive mixed-dentition treatment was an effective modality for early correction of Class II malocclusions.

    Since bat rabies surveillance was first implemented in France in 1989, 48 autochthonous rabies cases without human contamination have been reported using routine diagnosis methods. In this retrospective study, data on bats submitted for rabies testing were analysed in order to better understand the epidemiology of EBLV-1 in bats in France and to investigate some epidemiological trends. Of the 3176 bats submitted for rabies diagnosis from 1989 to 2013, 1.96% (48/2447 analysed) were diagnosed positive. Among the twelve recognised virus species within the Lyssavirus genus, two species were isolated in France. 47 positive bats were morphologically identified as Eptesicus serotinus and were shown to be infected by both the EBLV-1a and the EBLV-1b lineages. Isolation of BBLV in Myotis nattereri was reported once in the north-east of France in 2012. The phylogenetic characterisation of all 47 French EBLV-1 isolates sampled between 1989 and 2013 and the French BBLV sample against 21 referenced partial nucleoprotein sequences confirmed the low genetic diversity of EBLV-1 despite its extensive geographical range. Statistical analysis performed on the serotine bat data collected from 1989 to 2013 showed seasonal variation of rabies occurrence with a significantly higher proportion of positive samples detected during the autumn compared to the spring and the summer period (34% of positive bats detected in autumn, 15% in summer, 13% in spring and 12% in winter). In this study, we have provided the details of the geographical distribution of EBLV-1a in the south-west of France and the north-south division of EBLV-1b with its subdivisions into three phylogenetic groups: group B1 in the north-west, group B2 in the centre and group B3 in the north-east of France.

    Full Text Available Virechana (therapeutic purgation is a common procedure that is widely practiced among the panchakarma treatments (pentad treatments. Various Virechaka dravyas (purgative drugs have been described for Virechana. Even after critical analysis of Virechaka dravyas in the literature, still there is difficulty in the fixation of dose. Hence, the retrospective analysis of varied outcomes of Virechana with Danti (Baliospermum montanum avaleha (linctus is discussed in this paper. The study included twenty-seven case reports of patients who were administered Virechana with Danti avaleha. These case reports are of patients suffering from various ailments such as irregular menstrual cycles, polycystic ovarian syndrome, primary and secondary infertility, and psoriasis. Danti avaleha was administered at dose of 10 g and 5 g in the Krura (~strong and Madhyama (~moderate/normal Koshta (~GI tract patients, respectively. Among seven Krura koshta patients, three of them resulted with Pravara (excellent Shuddhi and other four resulted with Madhyama (medium Shuddhi. In twenty Madhyama koshta patients, sixteen of them resulted with avara (minimum Shuddhi and remaining four patients resulted with Madhyama shuddhi. Complications like Udara shoola (spasmodic pain of abdomen and Vamana (emesis were observed during Virechana. Majority of the patients suffered with Udara shoola were of Madhyama koshta. Vamana was seen in both Krura and Madhyama koshta patients. Irrespective of the type of Shuddhi and complications, all the patients resulted with Samyak Kaphaantiki Virikta lakshana (signs of perfect purgation with end expulsion of Kapha. The study concluded that the Krura koshta patients were tolerable for dose of 10 g and are expected to attain Pravara Shuddhi. Whereas Madhyama koshta patients were intolerable even to mild dose of 5 g, producing Avara shuddhi.

    To investigate whether plagiarism is more prevalent in publications retracted from the medical literature when first authors are affiliated with lower-income countries versus higher-income countries. Secondary objectives included investigating other factors associated with plagiarism (e.g., national language of the first author's country affiliation, publication type, journal ranking). Systematic, controlled, retrospective, bibliometric study. Retracted publications dataset in MEDLINE (search filters: English, human, January 1966-February 2008). Retracted misconduct publications were classified according to the first author's country affiliation, country income level, and country national language, publication type, and ranking of the publishing journal. Standardised definitions and data collection tools were used; data were analysed (odds ratio [OR], 95% confidence limits [CL], chi-squared tests) by an independent academic statistician. Of the 213 retracted misconduct publications, 41.8% (89/213) were retracted for plagiarism, 52.1% (111/213) for falsification/fabrication, 2.3% (5/213) for author disputes, 2.3% (5/213) for ethical issues, and 1.4% (3/213) for unknown reasons. The OR (95% CL) of plagiarism retractions (other misconduct retractions as reference) were higher (P 1 retraction) with publications retracted for plagiarism (11.5%, 9/78) than other types of misconduct (28.9%, 24/83). This is the first study to demonstrate that publications retracted for plagiarism are significantly associated with first authors affiliated with lower-income countries. These findings have implications for developing appropriate evidence-based strategies and allocation of resources to help mitigate plagiarism misconduct.

    To examine medium- to long-term orthodontic treatment stability and its possible association with certain variables. In a retrospective longitudinal study of 70 postretention patients, the Peer Assessment Rating (PAR) index was measured at the start (T1) and end (T2) of treatment and between 4 and 10 years afterwards (T3). The stability was considered absolute when the T2 and T3 values were identical and relative when the difference was within the ±5 range. Among the 70 patients, 65.8% were female and 34.2% were male. Their mean age was 14.5 years. The mean treatment length was 2.4 years. The mean retention phase was 3.3 years. The mean pre- and posttreatment PAR scores were 29.8 (T1) and 6.3 (T2). The mean T1-T2 difference was 23.6. The mean T2-T3 difference was -0.39. Within the study, 7.1% presented absolute stability and 68.6% presented relative stability. Lower anterior segment alignment and overbite were the most unstable occlusal features and tended to worsen. Fixed retainer (odds ratio [OR] 0.31; 95% confidence interval [CI] 0.10-0.98) as a protective factor and years without retention (OR 1.32; 95% CI 1.03-1.68) as a risk factor are predictor variables of instability in the case of lower anterior segment alignment. The PAR value at the end of treatment (OR 1.29; 95% CI 1.08-1.54) and extractions (OR 4.76; 95% CI 1.05-21.6) before treatment are predictors for midline instability.

    The poor outcome of patients with recurrent ovarian cancer constitutes a continuous challenge for decision-making in clinical practice. In this setting, molecular targets have recently been identified, and novel compounds are now available. Bevacizumab has been introduced for the treatment of patients with ovarian cancer and is, to date, the most extensively investigated targeted therapy in this setting. However, potential toxicities are associated with the use of this monoclonal antibody. These toxicities have been reported in clinical trials, and can also be observed outside of trials. As limited data is currently available regarding the safety of bevacizumab treatment in daily clinical practice, the current retrospective study was designed to evaluate this. Data from 156 patients with recurrent ovarian cancer who had received bevacizumab treatment between January 2006 and June 2009 were retrospectively identified from the institutional records of five French centers. In contrast to clinical trials, the patients in the present study were not selected and had a heterogeneous profile according to their prior medical history, lines of treatment prior to bevacizumab introduction and number of relapses. The results first confirm the effect of heavy pretreatment on the occurrence of serious and fatal adverse events in clinical practice, as previously reported for clinical trials and for other retrospective cohort studies. Importantly, the data also demonstrates, for the first time, that medical history of hypertension is an independent predictive risk factor for the development of high-grade hypertension during bevacizumab treatment. These results thus suggest that treating physicians must consider all risk factors for managing bevacizumab toxicity prior to its introduction. Such risk factors include the time of bevacizumab introduction, a patient's history of hypertension and a low incidence of pre-existing obstructive disease. PMID:26998090

    Amnioinfusion is a relatively recent procedure introduced among fetal medicine techniques. Its applications focus on two different methods: transcervical and transabdominal. The first procedure usually is carried out during "intrapartum amnioinfusion" to prevent or treat fetal heart rate (FHR) decelerations related to oligohydramnios or to dilute thick meconium staining of the amniotic fluid. The latter method used during "antepartum amnioinfusion" is usually indicated for severe oligohydramnios in order to avoid the complications related such as pulmonary hypoplasia, deforming effects of oligohydramnios, variable FHR decelerations and intraventricular hemorrhages. Antepartum amnioinfusion, also used to improve ultrasound visualisation in presence of oligohydramnios, is less employed as compared to intrapartum amnioinfusion, therefore its risks are not well established. In order to study possible adverse effects on the mother or foetus, fifty five patients affected by oligohydramnios at 17th-34th week of gestational age were submitted to antepartum amnioinfusion (1-5 procedures) and were matched retrospectively with forty seven women with the same characteristics treated with the conservative and expectant management. The trend of pregnancy was the same for both groups in relation to maternal fever > 38 degrees (10.9% in the amnioinfused group vs 17.0% in control group ns), leukocyte count > 18,000/mm3 (25.5% vs 21.3%, ns), C-reactive protein > 10 ng/ml (10.9% vs 6.4%, ns). The latency period between admission and delivery was significantly longer in the amnioinfused group than in the control one [21 (range 1-98) vs 9 days (range 0-72); p amnioinfused group than in the control group (32.3% vs 66.6%; p amnioinfusion seems to increase the latency period between premature rupture of membranes and delivery, but it remains to clarify if this procedure is as much safe for the fetus as for the mother.

    Full Text Available Introduction: Duodenal stump fistula (DSF after gastrectomy has a low incidence but a high morbidity and mortality, and is therefore one of the most aggressive and feared complications of this procedure. Material and methods: We retrospectively evaluated all DSF occurred at our hospital after carrying out a gastrectomy for gastric cancer, between January 1997 and December 2014. We analyzed demographic, oncologic, and surgical variables, and the evolution in terms of morbidity, mortality and hospital stay. Results: In the period covered in this study, we performed 666 gastrectomies and observed DSF in 13 patients (1.95%. In 8 of the 13 patients (61.5% surgery was the treatment of choice and in 5 cases (38.5% conservative treatment was carried out. Postoperative mortality associated with DSF was 46.2% (6 cases. In the surgical group, 3 patients developed severe sepsis with multiple organ failure, 2 patients presented a major hematemesis which required endoscopic haemostasis, 1 patient had an evisceration and another presented a subphrenic abscess requiring percutaneous drainage. Six patients (75% died despite surgery, with 3 deaths in the first 24 hours of postoperative care. The 2 patients who survived after the second surgical procedure had a hospital stay of 45 and 84 days respectively. In the conservative treatment group the cure rate was 100% with no significant complications and an average postoperative hospital stay of 39.5 days (range, 26-65 days. Conclusion: FMD is an unusual complication but it is associated with a high morbidity and mortality. In our experience, conservative management has shown better results compared with surgical treatment.

Br J Clin Pharmacol 2017; 83: 1163-5. https://doi.org/10.1111/bcp.13279 AIMS: Treatment of paracetamol (acetaminophen) overdose with acetylcysteine is standardized, with dose determined only by patient weight. The validity of this approach for massive overdoses has been questioned. We systematically compared outcomes in massive and non-massive overdoses, to guide whether alternative treatment strategies should be considered, and whether the ratio between measured timed paracetamol concentrations (APAP pl ) and treatment nomogram thresholds at those time points (APAP t ) provides a useful assessment tool. This is a retrospective observational study of all patients (n = 545) between 2005 and 2013 admitted to a tertiary care toxicology service with acute non-staggered paracetamol overdose. Massive overdoses were defined as extrapolated 4-h plasma paracetamol concentrations >250 mg l -1 , or reported ingestions ≥30 g. Outcomes (liver injury, coagulopathy and kidney injury) were assessed in relation to reported dose and APAP pl :APAP t ratio (based on a treatment line through 100 mg l -1 at 4 h), and time to acetylcysteine. Ingestions of ≥30 g paracetamol correlated with higher peak serum aminotransferase (r = 0.212, P paracetamol overdose are at higher risk of organ injury, even when acetylcysteine is administered early. Enhanced therapeutic strategies should be considered in those who have an APAP pl :APAP t  ≥ 3.

    To evaluate the population of cleft patients treated in a Department of Orthodontics and the types of treatment modalities provided. Demographic, cleft related and treatment related data existing in the patients' files were supplemented by questionnaires. Comparisons were conducted among 3 cleft groups: cleft lip (CL), cleft lip and palate (CLP) and cleft palate (CP). The response rate was 36% (n = 152). The distribution of the patients in the 3 cleft groups, the sidedness, the male predominance and association with additional anomalies were similar to the reports in the literature. Most of the patients were the 3rd born (or more) and were of normal birth weight. Consanguity in the cleft families was at least 2.5 times more prevalent than that of the Israeli population and 30% reported on additional cleft in the family. Low birth weight and additional anomalies were found mainly in the CP group. Orthodontic involvement spanned 3 developmental periods: immediate postnatal presurgical treatment, phase I between the ages 6-8 years and full orthodontic treatment at a later age. Up to the age of 5 years only one lip operation was performed for 60% of the lip-affected children and one palate operation for 65% of the palate affected patients. 1. The distribution of the various cleft-related parameters in this retrospective study was similar to the findings in the literature. 2. The high prevalence of additional anomalies found emphasizes the need for a thorough examination of the cleft babies. 3. Orthodontic treatment was rendered in one and two phase protocols in addition to immediate postnatal pre-surgical intervention.

    To determine the clinical characteristics of Continuous Neuropathic Orofacial Pain in patients that suffer Persistent Idiopathic Facial Pain (PIFP), Painful Post-Traumatic Trigeminal Neuropathy (PPTTN) or Burning Mouth Syndrome (BMS) and to describe their treatment. A retrospective observational study was made, reviewing the clinical history of the patients diagnosed with Continuous Neuropathic Orofacial Pain between 2004 and 2011 at the Orofacial Pain Unit of the Master of Oral Surgery and Implantology of the University of Barcelona and at the Orofacial Pain Unit of the Teknon Medical Center of Barcelona. The average age of the patients with Continuous Neuropathic Orofacial Pain was 54.5, with a clear female predominance (86.9%, n=20). Of all patients, 60.9% (n=14) were suffering a PIFP, 21.7% (n=5) had a BMS and 17.4% (n=4) were presenting a PPTTN. The pain quality described by the patients with Continuous Neuropathic Orofacial Pain was oppressive (43.47%, n=10), widely represented by patients with PIFP, and burning (39.13%, n=9) being the only quality that described patients with BMS. The treatment carried out with the patients was only pharmacologic. The most used drugs for the treatment of PIFP and PPTTN were clonazepam (50%, n=9) and amitriptyline (44.44%, n=8). However, a 55.5% (n=10) of the patients with PIFP or PPTTN required the association of two or more drugs for a correct pain control. All the patients with BMS responded satisfactorily to clonazepam. Continuous Neuropathic Orofacial Pain is a little known condition among the general population, physicians and dentists. This favors a late diagnosis and inaccurate treatments which entail unnecessary suffering. It is important to inform both the general population and health professionals concerning this painful condition.

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer

    Complications from diabetes mellitus including major lower extremity amputation may have significant impact on a patient's mortality. This study determined what impact the addition of a limb salvage and diabetic foot program involving podiatry had at an academic institution over 16years by analyzing high-low amputation ratio data. The high-low amputation ratio in the diabetic population who underwent non-traumatic amputation of the lower extremity was retrospectively evaluated at an academic institution via cohort discovery of the electronic medical record and analysis of billing over 16years. We directly compared two eras, one without podiatry and one with a podiatry presence. It was found that with the addition of a podiatry program, limb salvage rates significantly increased (R 2 (without podiatry)=0.45, R 2 (with podiatry)=0.26), with a significant change in both the rate of limb salvage per year (-0.11% per year versus -0.36% per year; ppodiatry to 0.60 with podiatry). Of note, approximately 40 major lower extremity amputations were avoided per year with the addition of a podiatry program (ppodiatry program present at an academic institution, major lower extremity amputations can be avoided and more limbs can be salvaged, thus preventing some of the moribund complications from this condition.

    The aim of this retrospective study was to investigate the most frequent complications and assess their overall rate associated with the surgical extraction of impacted teeth in an elderly patient population. Oral health needs of the elders are often associated with surgical procedures for the creation of appropriate conditions for any further prosthetic treatment. One such process is the removal of severely decayed, fractured or impacted teeth detrimental to the fit or appearance of dentures. While broken and decayed teeth leave little doubt for their removal, impacted teeth divide opinion, some extreme regarding their prophylactic removal and the appropriate age for the procedure. Material was selected from the archives of an Out-Patient Dental Surgery Clinic of the Regional Centre of Dentistry in Szczecin, from 2002 to 2013. The database was independently screened by two investigators according to inclusion and exclusion criteria. After selection process, all included records were screened using a data extraction form to obtain the necessary data. The total number of impacted teeth was 73, of which 29% were partially impacted. The overall complication rate was 24.6%. The most common complications were as follows: haematoma, nerve disturbances and local infections. Surgical extraction in patients above 60 years of age is fraught with a high risk of possible complications. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    Full Text Available Otomycosis is a fungal infection of the external ear canal with only a few studies about its real frequence in Brazil. AIM: to evaluate otomycosis frequence and characteristics in patients with clinical suspicion of external otitis. STUDY DESIGN: Retrospective study with transversal cohort (2000-2006. MATERIALS AND METHODS:103 patients were assigned to mycological diagnosis (direct microscopic examination and culture. RESULTS: Otomycosis was diagnosed in 19.4% of the patients. Patient age varied from 2 to 66 years (an average of 23.5 years of age, and 60% of otomycosis cases were seen in women between 2 to 20 years of age. Chronic otitis, previous antibiotic therapy and the lack of cerumen were predisposing factors; itching, otalgia, otorrhea and hypoacusis were the symptoms reported by the patients. The most frequently isolated species were C. albicans (30%, C. parapsilosis (20%, A. niger (20%, A. flavus (10%, A. fumigatus (5%, C. tropicalis (5%, Trichosporon asahii (5% and Scedosporium apiospermum (5%. CONCLUSIONS: Otomycosis is endemic in João Pessoa-PB. Clinical exam and mycological studies are important for diagnostic purposes because otomycosis symptoms are not specific.Otomicose é uma infecção fúngica do conduto auditivo externo com poucos estudos sobre sua real frequência no Brasil.

    Atypical squamous cells of undetermined significance (ASCUS) are a cervical cytologic finding category suggestive but not definitive of squamous intraepithelial lesions. ASCUS remains an incompletely described entity and accounts for even 5%-10% of reported Papanicolaou (Pap) smears. The management of women with such cytologic findings remains controversial. The aim of this study was to evaluate the cytology laboratory findings with regards to ASCUS diagnosis, using cervical Pap smears, and colposcopic biopsies, as well as their management. This is a retrospective study of patients with ASCUS Pap smears taken during the period January 2010 - December 2010 in the Second Department of Obstetrics and Gynecology, Aretaieion Hospital. During the study period, 657 Pap smears were examined at the Aretaieion Hospital; moreover, seven patients, whose Pap smears were cytologically diagnosed with ASCUS, were referred from other clinics, providing a total of 42 cases with a descriptive diagnosis of ASCUS for review. Of the 42 cases, eight were not studied because they were either lost in follow-up or they did not have available data. The remaining 34/42 patients were evaluated by colposcopic examination and directed biopsies where necessary. The ratio of ASCUS to low-grade squamous intraepithelial lesion (LGSIL), high-grade squamous cell intraepithelial lesion (HGSIL) or squamous cell carcinoma (SCC) was 5/34, 1/34, and 0/34, respectively. In the 34 ASCUS cases evaluated by colposcopy, the age distribution varied from 22 to 54 years. Eight of 34 cases did not have a child, 7/34 were primigravida, 18/34 were secondi-gravida, and 1/34 had four children. Four out of 34 cases were postmenopausal, 3/34 referred no history of abnormal bleeding, 21/34 were smokers, 6/34 used oral contraceptives, 2/34 used intrauterine devices, 1/34 took replacement of hormones, 4/34 had prior abnormal Pap smears human papillomavirus (HPV), or 1/34 had previous cancer (breast cancer).

    Full Text Available Bevacizumab (BEV, a humanized anti-vascular endothelial growth factor (VEGF monoclonal antibody, enhances the antitumor effectiveness of paclitaxel (PTX-based chemotherapy in many metastatic cancers. A recent study in mice showed that VEGF receptor inhibitors can interfere with the neuroprotective effects of endogenous VEGF, potentially triggering the exacerbation of PTX-induced neuropathy. In clinical trials, exacerbation of neuropathy in patients who received PTX combined with BEV (PTX+BEV has generally been explained by increased exposure to PTX owing to the extended duration of chemotherapy. We investigated whether the concurrent use of BEV is associated with the exacerbation of PTX-induced neuropathy.Female patients with breast cancer who had received weekly PTX or PTX+BEV from September 2011 through May 2016 were studied retrospectively. PTX-induced neuropathy was evaluated at the same time points (at the 6th and 12th courses of chemotherapy in both cohorts. A multivariate Cox proportional-hazards model was used to assess the independent effect of BEV on the time to the onset of neuropathy.A total of 107 patients (median age, 55 years; range, 32-83 were studied. Sixty-one patients received PTX as adjuvant chemotherapy, 23 received PTX for metastatic disease, and 23 received PTX+BEV for metastatic disease. Peripheral sensory neuropathy was worse in patients who received PTX+BEV than in those who received PTX alone: at the 6th course, Grade 0/1/2/3 = 4/13/4/0 vs. 25/42/6/0 (P = 0.095; at the 12th course, 2/3/11/3 vs. 7/30/23/2 (P = 0.016. At the 12th course, the incidence of Grade 2 or higher neuropathy was significantly higher in patients treated with PTX+BEV than in those treated with PTX alone (74% vs. 40%; P = 0.017. In multivariate analysis, BEV was significantly associated with an increased risk of neuropathy (HR 2.32, 95% CI 1.21-4.44, P = 0.012.The concurrent use of BEV could worsen PTX-induced neuropathy in patients with breast

    Hemorrhage after blunt trauma is a major contributor to death after trauma. In the abdomen, an injured spleen is the most frequent cause of major bleeding. Splenectomy is historically the treatment of choice. In 2007, non-operative management (NOM) with splenic artery embolization (SAE) was introduced in our institution. The indication for SAE is hemodynamically stable patients with extravasation of contrast, or grade 3-5 spleen injury according to the Abbreviated Organ Injury Scale 2005, Update 2008. We wanted to examine if the introduction of SAE increased the rate of salvaged spleens in our trauma center. All patients discharged with the diagnosis of splenic injury in the period 01.01.2000 - 31.12.2013 from the University Hospital of North Norway Tromsø were included in the study. Patients admitted for rehabilitation purposes or with an iatrogenic injury were excluded. A total of 109 patients were included in the study. In the period 2000-7, 20 of 52 patients were splenectomized. During 2007-13, there were 6 splenectomies and 24 SAE among 57 patients. The reduction in splenectomies is significant (p < 0.001). There is an increase in the rate of treated patients (splenectomy and SAE) from 38 to 53 % in the two time periods, but not significantly (p = 0.65). The rate of salvaged spleens has increased after the introduction of SAE in our center. The study is registered at www.clinicaltrials.gov with the identification number NCT01965548.

    Uterine carcinosarcomas are highly aggressive tumors of the uterus associated with a poor prognosis. Though initially classified as sarcomas, now these tumors are classified as carcinomas. The management approach of carcinosarcomas has also changed from those used for high grade sarcomas to that used for managing high grade endometrial carcinomas. The purpose of our study was to analyze the management and outcome of patients with uterine carcinosarcomas treated at our institution and also to attempt a brief review regarding the management of uterine carcinosarcomas. We did a retrospective analysis of all patients with a diagnosis of carcinosarcoma of the uterus treated at our Institution from January 2005 till December 2010. All Patients with a pathological diagnosis of carcinosacrcoma or malignant mixed mullerian tumours of the uterus were included. Data was obtained from the hospital electronic medical records and the hospital cancer registry. Data was analyzed using SPSS v.17. During this 6 year period we had 20 patients with carcinosarcoma of the uterus. 75 % of the patients belonged to Stage I and II. 95 % of the patients underwent Hysterectomy with Bilateral salpingo oophorectomy and 60 % had lymphadenectomy also along with hysterectomy.8 patients had disease recurrence . In patients who had gross extrauterine disease at the time of surgery , the survival was only 9 months whereas in patients who had complete staging with disease confined to the uterus , the survival was 36 months. Carcinosarcomas, accounts for more than 15 % of the uterine cancer associated deaths. Surgery remains the cornerstone of management for these tumors and surgery with pelvic and para aortic lymphadenectomy and peritoneal and omental biopsies is required for the correct staging of the disease and may also provide a survival advantage. Radiation therapy has been shown to provide only better local control without any survival advantage. Further studies are needed to assess

Performance and sporting dogs were 39.4% of the population, with 58.1% of them being agility dogs. Pain was elicited on palpation of the supraspinatus tendon in 49.3% of dogs. Shoulder radiographs in 283 dogs showed mineralisation in 13% of cases. MRI of the shoulder was performed in 31 cases and revealed findings indicative of ST, including hyperintensity of signal on T1 weighted image (or “spin-lattice” and Short T1 Inversion Recovery (STIR sequences of the supraspinatus tendon at its insertion on the greater tubercle and mineralisation of the supraspinatus tendon. Common ultrasonographic findings included increased tendon size (76%, irregular fibre pattern (74%, and non-homogeneous echogenicity (92.5%. The most common findings on shoulder arthroscopy were supraspinatus bulge (82.2% and subscapularis pathology (62.4%. Elbow pathology was recorded in 54.5% of dogs. Treatment outcomes showed 74.6% of dogs failed to respond to non-steroidal anti-inflammatory drugs (NSAID and 40.8% failed to respond to rehabilitation. Conclusions: These findings suggest concurrent shoulder and/or elbow pathology is not uncommon in dogs with ST. Further, ST often fails to respond to NSAID therapy and rehabilitation

    Many previous reports have focused on bile leakage after liver resection. Despite the improvements in surgical techniques and perioperative care the incidence of this complication rather keeps increasing. A number of predictive factors have been analyzed. There is still no consensus regarding their influence on the formation of bile leakage. The objective of our analysis was to evaluate the incidence of bile leakage, its impact on mortality and duration of hospitalization at our department. At the same time, we conducted an analysis of known predictive factors. The authors present a retrospective review of the set of 146 patients who underwent liver resection at the Department of Surgery of the 2nd Faculty of Medicine of the Charles University and Central Military Hospital Prague, performed between 20102013. We used the current ISGLS (International Study Group of Liver Surgery) classification to evaluate the bile leakage. The severity of this complication was determined according to the Clavien-Dindo classification system. Statistical significance of the predictive factors was determined using Fishers exact test and Students t-test. The incidence of bile leakage was 21%. According to ISGLS classification the A, B, and C rates were 6.5%, 61.2%, and 32.3%, respectively. The severity of bile leakage according to the Clavien-Dindo classification system - I-II, IIIa, IIIb, IV and V rates were 19.3%, 42%, 9.7%, 9.7%, and 19.3%, respectively. We determined the following predictive factors as statistically significant: surgery for malignancy (pBile leakage significantly prolonged hospitalization time (pbile leakage the perioperative mortality was 23 times higher (pBile leakage is one of the most serious complications of liver surgery. Most of the risk factors are not easily controllable and there is no clear consensus on their influence. Intraoperative leak tests could probably reduce the incidence of bile leakage. In the future, further studies will be required to improve

    We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients. This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS) rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates. Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68%) presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year. Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered.

    Over the last decade, laparoscopic hepatic surgery (LHS) has been increasingly performed throughout the world. Meanwhile, ambulatory surgery has been developed and implemented with the aims of improving patient satisfaction and reducing health care costs. The objective of this study was to report our preliminary experience with ambulatory minimally invasive LHS. Between 1999 and 2014, 172 patients underwent LHS at our institution, including 151 liver resections and 21 fenestrations of hepatic cysts. The consecutive series of highly selected patients who underwent ambulatory LHS were included in this study. Twenty patients underwent ambulatory LHS. Indications were liver cysts in 10 cases, liver angioma in 3 cases, focal nodular hyperplasia in 3 cases, and colorectal hepatic metastasis in 4 cases. The median operative time was 92 minutes (range: 50-240 minutes). The median blood loss was 35 mL (range: 20-150 mL). There were no postoperative complications or re-hospitalizations. All patients were hospitalized after surgery in our ambulatory surgery unit, and were discharged 5-7 hours after surgery. The median postoperative pain score at the time of discharge was 3 (visual analogue scale: 0-10; range: 0-4). The median quality-of-life score at the first postoperative visit was 8 (range: 6-10) and the median cosmetic satisfaction score was 8 (range: 7-10). This series shows that, in selected patients, ambulatory LHS is feasible and safe for minor hepatic procedures. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    The use of abdominal radiographs contributes to increased healthcare costs, radiation exposure, and potentially to misdiagnoses. We evaluated the association between abdominal radiograph performance and emergency department (ED) revisits with important alternate diagnosis among children with constipation. Retrospective cohort study of children aged constipation at one of 23 EDs from 2004 to 2015. The primary exposure was abdominal radiograph performance. The primary outcome was a 3-day ED revisit with a clinically important alternate diagnosis. RAND/University of California, Los Angeles methodology was used to define whether the revisit was related to the index visit and due to a clinically important condition other than constipation. Regression analysis was performed to identify exposures independently related to the primary outcome. A total of 65.7% (185 439/282 225) of children with constipation had an index ED visit abdominal radiograph performed. Three-day revisits occurred in 3.7% (10 566/282 225) of children, and 0.28% (784/282 225) returned with a clinically important alternate related diagnosis. Appendicitis was the most common such revisit, accounting for 34.1% of all 3-day clinically important related revisits. Children who had an abdominal radiograph performed were more likely to have a 3-day revisit with a clinically important alternate related diagnosis (0.33% vs 0.17%; difference 0.17%; 95% CI 0.13-0.20). Following adjustment for covariates, abdominal radiograph performance was associated with a 3-day revisit with a clinically important alternate diagnosis (aOR: 1.39; 95% CI 1.15-1.67). Additional characteristics associated with the primary outcome included narcotic (aOR: 2.63) and antiemetic (aOR: 2.35) administration and underlying comorbidities (aOR: 2.52). Among children diagnosed with constipation, abdominal radiograph performance is associated with an increased risk of a revisit with a clinically important alternate related diagnosis

  19. NATO Advanced Study Institute on Metal Hydrides

    CERN Document Server

    1981-01-01

    In the last five years, the study of metal hydrides has ex­ panded enormously due to the potential technological importance of this class of materials in hydrogen based energy conversion schemes. The scope of this activity has been worldwide among the industrially advanced nations. There has been a consensus among researchers in both fundamental and applied areas that a more basic understanding of the properties of metal/hydrogen syster;,s is required in order to provide a rational basis for the selection of materials for specific applications. The current worldwide need for and interest in research in metal hydrides indicated the timeliness of an Advanced Study Insti­ tute to provide an in-depth view of the field for those active in its various aspects. The inclusion of speakers from non-NATO coun­ tries provided the opportunity for cross-fertilization of ideas for future research. While the emphasis of the Institute was on basic properties, there was a conscious effort to stimulate interest in the applic...

    2017-10-01

    A multi-institutional study aimed at mapping the space of quasi-axisymmetric stellarators has begun. The goal is to gain improved understanding of the dependence of important physics and engineering parameters (e.g. bootstrap current, stability, coil complexity, etc.) on plasma shape (average elongation, aspect ratio, number of periods). In addition, the stellarator optimization code STELLOPT will be upgraded with new capabilities such as improved coil design algorithms such as COILOPT + + and REGCOIL, divertor optimization options, equilibria with islands using the SPEC code, and improved bootstrap current calculations with the SFINCS code. An effort is underway to develop metrics for divertor optimization. STELLOPT has also had numerous improvements to numerical algorithms and parallelization capabilities. Simultaneously, we also are pursuing the optimization of turbulent transport according to the method of proxy functions. Progress made to date includes an elongation scan on quasi-axisymmetric equilibria and an initial comparison between the SFINCS code and the BOOTSJ calculation of bootstrap current currently available in STELLOPT. Further progress on shape scans and subsequent physics analysis will be reported. The status of the STELLOPT upgrades will be described. The eventual goal of this exercise is to identify attractive configurations for future US experimental facilities.. This work is supported by US DoE Contract Number DE-AC02-09CH11466.

    Full Text Available Aim. The aim of our study was to determine the prevalence of psoriatic arthritis in the patients with psoriasis and to analyze retrospectively the results of a 34-year multidisciplinary management of the patients with psoriatic arthritis. Methods. The study included 162 out of 183 treated patients with psoriatic arthritis, aged 48 ± 15 years. All the patients satisfied the current diagnostic criteria for psoriasis and psoriatic arthritis according to the American College of Rheumatology. Results. Psoriatic arthritis developed in 183 (9.3% out of 1976 patients with psoriasis. Time interval for establishing the diagnosis was 4 years. A positive family history of the disease had 15.0% of the studied patients. Its onset was most often at 42 years of age in 70.4% of the cases, and 2 months to 59 years after the appearance of psoriasis. Psoriatic arthritis without psoriasis appeared in 1.8% of the patients. A severe form of arthritis had 64.2% of the patients, mainly the patients with scalp psoriasis (χ2=3.2; p<0.05. Nail changes had 35% of the patients. Distal interphalangeal joints were involved in 63.6%, axial skeleton in 36.4%, oligoarthritis in 45.0%, polyarthritis in 55.0%, and mutilating form in 6.8% of the patients. Elevated Erythrocyte Sedimentation Rate was reveald in 61.7% of the patients. Immunoglobulin M (IgM rheumatoid factor was altered in 4.3% of the patients. The human leukocyte antigen (HLA typing in the 28 patients were: A2 32.0%, A3 18.0%, Al and A9 14.0%, A28 and A29 3.5%, B8 and B16 14.0%, B5 and B12 11.0%, B13,B15, B18, B27 and B35 7.0%. Radiologic changes were most often in hand and foot joints, less frequently in the knees and quite infrequently in hips and shoulders joints. Sacroiliitis was found in 46.4% of the patients. Psoriasis was treated with topical corticosteroids and salicylic ointments in all the patients, ultraviolet (PUVA therapy in 5.6% and retinoids in 4.3% of them. Artrithis was treated with nonsteroidal anti

    Full Text Available To review clinical characteristics of pigmented villonodular synovitis (PVNS in China.Electronic medical records (EMR of four Chinese institutes were queried for patients with histologically proven PVNS between January 2005 and February 2014. Their data were collected including gender, age at diagnosis, clinical presentation, affected site, symptom duration, comorbidities, treatment strategy, recurrence and routine laboratories.A total of 237 patients with biopsy-proven PVNS were investigated. The gender ratio was 1.35 for a female predominance (101 males and 136 females. The average age was 36 years (range, 2 to 83 years. The median delay from initial clinical symptom to diagnosis was 18 months. Main affected areas were the knee (73.84% and the hip (18.14%. Forty patients had a clear history of joint trauma. Six patients were concurrently diagnosed with PVNS and avascular necrosis (AVN. Five patients suffered from PVNS following implantation of orthopaedic devices including artificial prosthesis, plate and wire. One hundred and twenty-nine patients underwent arthroscopic synovectomy and 108 open synovectomy. Altogether 48 patients (26 males and 22 females had recurrence of disease. The relapse rate was 24% (knee and 6.98% (hip, 20.93% (open surgery and 19.44% (arthroscopy, respectively. Erythrocyte sedimentation rate (ESR and C-reactive protein (CRP rate were elevated in 45.83% and 38.41% of the patients respectively.To our knowledge, this study is the largest sample size of PVNS patients reported as well as the largest sample of PVNS with concurrent AVN reported to date. Our outcomes suggest that PVNS shows a female predominance, occurs mostly between 20-40 years and favors the knee and hip. Recurrence is frequent, particularly in the knee. Serum ESR and CRP may be elevated in some patients. Additionally, the present study supports the theory of an association between PVNS and orthopedic surgery, which is not limited to joint replacement.

    To evaluate the clinico-pathological findings, response to treatment and prevalence of complications in dogs with primary hypoparathyroidism. Retrospective study of 17 dogs presenting to the University of Melbourne Veterinary Clinical Centre and Murdoch University Veterinary Hospital over a 15 year period (1990 to 2004). Case records were evaluated for signalment, body weight, diet type, historical and clinical findings, serum total calcium, phosphate, albumin and parathyroid hormone concentrations, urinary fractional excretion ratios of calcium and phosphate, electrocardiogram (ECG) results, treatments administered, outcome and period of follow-up. The most common breeds identified were St Bernard (three dogs), Chihuahua (two dogs), German Shepherd (two dogs) and Jack Russell Terrier (two dogs). Three dogs were cross bred. Seizures, muscle tremors and fasciculations, stiff gait, tetany, muscle cramping, behavioural change and hyperventilation were the most common clinical signs. Vomiting, inappetence, diarrhoea, abdominal pain, hyperthermia, facial pruritus, ataxia, weakness, cataracts, and circling also occurred with less frequency. The mean duration of observed clinical signs preceding diagnosis was 33 days (median 13 days, range 1 to 173 days). All dogs had marked hypocalcaemia with normal or mildly increased serum albumin concentrations. Mean phosphate concentrations were significantly higher in inappetent dogs (P = 0.049). Mean serum calcium concentrations were significantly lower in dogs with cataracts compared to those without (P = 0.046). There were no other significant relationships between serum calcium or phosphate concentrations and the clinical presentation or outcome. No significant correlations were identified between the presence of a particular clinical sign and the duration of clinical signs. ECGs were obtained in four dogs and all exhibited QT interval prolongation due to a ST-segment prolongation. Sixteen of 17 dogs were treated successfully

    Full Text Available Abstract Background Non-brucellar and non-tuberculous infectious sacroiliitis (ISI is a rare disease, with misleading clinical signs that delay diagnosis. Most observations are based on isolated case reports or small case series. Our aim was to describe the clinical, bacteriological, and radiological characteristics of ISI, as well as the evolution of these arthritis cases under treatment. Methods This retrospective study included all ISI cases diagnosed between 1995 and 2011 in eight French rheumatology departments. ISI was diagnosed if sacroiliitis was confirmed bacteriologically or, in the absence of pathogenic agents, if clinical, biological, and radiological data was compatible with this diagnosis and evolution was favourable under antibiotic therapy. Results Overall, 39 cases of ISI were identified in adults, comprising 23 women and 16 men, with a mean age at diagnosis of 39.7 ± 18.1 years. The left sacroiliac joint (SI was affected in 59% of cases, with five cases occurring during the post-partum period. Lumbogluteal pain was the most common symptom (36/39. Manipulations of the SI joint were performed in seven patients and were always painful. Mean score for pain using the visual analogue score was 7.3/10 at admission, while 16 patients were febrile at diagnosis. No risk factor was found for 30.7% of patients. A diagnosis of ISI was only suspected in five cases at admission. The mean time to diagnosis was long, being 43.3 ± 69.1 days on average. Mean C-reactive protein was 149.7 ± 115.3 mg/l, and leukocytosis (leukocytes ≥ 10 G/l was uncommon (n = 15 (mean level of leukocytes 10.4 ± 3.5 G/l. Radiographs (n = 33 were abnormal in 20 cases, revealing lesions of SI, while an abdominopelvic computed tomography (CT scan (n = 27 was abnormal in 21 cases, suggesting arthritis of the SI joints in 13 cases (48.1% and a psoas abscess in eight. Bone scans (n = 14 showed hyperfixation of the SI in 13 cases

    To report clinical findings, perioperative complications and long-term outcome in dogs and cats that had hemipelvectomy surgery for treatment of neoplasia. Multi-institutional retrospective case series. Dogs (n = 84) and cats (16). Medical records (January 2000 to December 2009) of dogs and cats that had hemipelvectomy at participating institutions were reviewed. Postoperative progress and current status of the patient at the time of the study was determined by either medical record review, or via telephone contact with the referring veterinarian or owner. Complications were infrequent and usually minor. Hemorrhage was the main intraoperative complication; 2 dogs required blood transfusion. One dog developed an incisional hernia. In dogs, hemangiosarcoma had the worst prognosis with a median survival time (MST) of 179 days. MST for chondrosarcoma (1232 days), osteosarcoma (533 days), and soft tissue sarcoma (373 days) were not statistically different. Median disease-free interval (DFI) for local recurrence of all tumor types was 257 days. Cats had 75% survival at 1 year, which was significantly longer than dogs. Survival times for most tumor types can be good, but surgical margins should be carefully evaluated to ensure complete tumor removal. Adjuvant therapies may be advisable particularly for dogs to reduce rates of local recurrence or distant metastasis. © Copyright 2013 by The American College of Veterinary Surgeons.

    To compare clinical outcomes and institutional costs of elective laparoscopic and open incisional hernia mesh repairs and to identify independent predictors of prolonged operative time and hospital length of stay (LOS). Retrospective observational cohort study on 269 consecutive patients who underwent elective incisional hernia mesh repair, laparoscopic group (N = 94) and open group (N = 175), between May 2004 and July 2014. Operative time was shorter in the laparoscopic versus open group (p costs were lower (p = 0.02). At Cox regression analysis adjusted for potential confounders, large wall defect (W3) and higher operative risk (ASA score 3-4) were associated with prolonged operative time, while midline hernia site was associated with increased hospital LOS. Open surgical approach was associated with prolongation of both operative time and LOS. Laparoscopic approach may be considered safely to all patients for incisional hernia repair, regardless of patients' characteristics (age, gender, BMI, ASA score, comorbidities) and size of the wall defect (W2-3), with the advantage of shorter operating time and hospital LOS that yields reduced total institutional costs. Patients with higher ASA score and large hernia defects are at risk of prolonged operative time, while an open approach is associated with longer duration of surgical operation and hospital LOS.

    One half of high-risk germ cell tumor (HRGCT) patients relapse after standard chemotherapy. This phase II study evaluated prospectively the toxicity and efficacy in first-line of the paclitaxel-ifosfamide-cisplatin combination (TIP) in HRGCT patients and tried to identify biomarkers that may allow patient-tailored treatments. Between October 1997- September 2000, 28 chemo-naive HRGCT patients were enrolled. Patients received 4 cycles of TIP (paclitaxel 175 mg/m(2) day 1/; ifosfamide 1.2 g/m(2)/day, days 1-5; Mesna 1.2 g/m(2)/day, days 1-5; and cisplatin 20 mg/m(2)/day, days 1-5 every 3 weeks). A non-randomized comparison was made between HRGCT patients treated in the same period with first-line TIP and bleomycin-etoposide-cisplatin (BEP) (28 patients vs 20). In 17 HRGCT patients treated between 1998-2006, ERCC1, Topoisomerase 1 and 2A, p53 and HER-2 expression was retrospectively analysed by immunohistochemistry (IHC) (7 patients with TIP, 10 with BEP), and correlations were made with response to chemotherapy and survival. With a median follow-up of 72 months [range 48+...89+], 5-year disease free survival (DFS) was 55%, with 95% CI 36-72, and the overall survival (OS) was 63%, with 95% CI 44-78. In June 2015, with a median follow-up of 196.47 months (range 177.30-209.27) (>15 years), 12 [%?] patients were alive and disease-free, and 16 [%?] had died (12 specific causes). There was no significant correlation between the expression of ERCC1, Topoisomerase 1 and 2A, HER-2 and p53 and response to treatment. Long-term follow-up showed no difference in OS between TIP vs BEP as first-line therapy. Both regimens had mild toxicity.

    Full Text Available Abstract Background Nausea and vomiting is a problem for children after neurosurgery and those requiring posterior fossa procedures appear to have a high incidence. This clinical observation has not been quantified nor have risk factors unique to this group of children been elucidated. Methods A six year retrospective chart audit at two Canadian children's hospitals was conducted. The incidence of nausea and vomiting was extracted. Hierarchical multivariable logistic regression was used to quantify risk and protective factors at 120 hours after surgery and early vs. late vomiting. Results The incidence of vomiting over a ten day postoperative period was 76.7%. Documented vomiting ranged from single events to greater than 20 over the same period. In the final multivariable model: adolescents (age 12 to Conclusion The incidence of vomiting in children after posterior fossa surgery is sufficient to consider all children requiring these procedures to be at high risk for POV. Nausea requires better assessment and documentation.

    Full Text Available STUDY DESIGN: A retrospective clinical study. OBJECTIVE: To evaluate the clinical efficacy of the surgical treatment of noncontiguous spinal tuberculosis (NSTB, and to discuss its therapeutic strategies. METHODS: We performed a retrospective review of clinical and radiographic data that were prospectively collected on 550 consecutive spinal tubercular patients including 27 patients who were diagnosed and treated as NSTB in our institution from June 2005 to June 2011. Apart from 4 patients being treated conservatively, the remainder received surgery by posterior transforaminal debridement, interbody fusion with instrumentation, posterior instrumentation and anterior debridement with fusion in a single or two-stage operation. The clinical outcomes were evaluated before and after treatment in terms of hematologic and radiographic examinations, bone fusion and neurologic status. The Oswestry Disability Index score was determined before treatment and at the last follow-up visit. RESULTS: 23 patients (15 M/8F, averaged 44.6 ± 14.2 years old (range, 19 to 70 yd, who received surgical treatment, were followed up after surgery for a mean of 52.5 ± 19.5 months (range, 24 to 72 months. The kyphotic angle was changed significantly between pre- and postoperation (P<0.05. The mean amount of correction was 12.6 ± 7.2 degrees, with a small loss of correction at last follow-up. All patients achieved solid bone fusion. No patients with neurological deficit deteriorated postoperatively. Neither mortalities nor any major complications were found. There was a significant difference of Oswestry Disability Index scores between preoperation and the final follow-up. CONCLUSION: The outcomes of follow-up showed that posterior and posterior-anterior surgical treatment methods were both viable surgical options for NSTB. Posterior transforaminal debridement, interbody fusion and posterior instrumentation, as a less invasive technique, was feasible and effective to treat

    Objective To explore potential risk factors and early manifestations of avoidant personality disorder (AVPD) by examining retrospective reports of social functioning and adverse childhood experiences. Method Early social functioning and pathological childhood experiences were assessed using the Childhood Experiences Questionnaire-Revised. The responses of 146 adults diagnosed with primary AVPD were compared with a group of 371 patients with other personality disorders as a primary diagnosis and a group of 83 patients with current major depression disorder and no personality disorders, using χ2 analyses. Diagnoses were based on semistructured interviews by trained reliable clinicians. Results Adults with AVPD reported poorer child and adolescent athletic performance, less involvement in hobbies during adolescence, and less adolescent popularity than the depressed comparison group and the other personality disorder group. Reported rates of physical and emotional abuse were higher than the depressed group, but this result was influenced by comorbid diagnoses. Conclusions These results suggest that early manifestations of AVPD are present in childhood but that various forms of abuse are not specific to the disorder. PMID:12960713

    Juvenile localized scleroderma includes different conditions characterized by skin hardening with increased collagen deposition. Although juvenile localized scleroderma is considered a relatively benign disease, lesions may extend through the dermis, subcutaneous tissue, muscles, and the underlying bone, leading to significant functional and cosmetic deformities. Furthermore, extracutaneous manifestations are described. We retrospectively analyzed a cohort of 26 patients with severe Juvenile localized scleroderma with particular attention to clinical features, therapy, and long-term outcome. A subgroup of three patients has been further evaluated with infrared thermography. Our findings were consistent with the current literature for demographic, laboratory, and clinical characteristics at disease onset, but, with our patients, the prevalence of extracutaneous manifestations was higher, thus confirming the potential for severe juvenile localized scleroderma to affect organs other than the skin, without increased risk of development toward systemic sclerosis. Correlation between various treatments and clinical endpoint showed that systemic therapy lead to a better outcome: in particular, methotrexate appeared the most effective drug, capable in halting the progression of the disease and sometimes inducing its regression. © 2010 Wiley Periodicals, Inc.

  17. Evolutionary institutionalism.

    Science.gov (United States)

    Fürstenberg, Dr Kai

    Institutions are hard to define and hard to study. Long prominent in political science have been two theories: Rational Choice Institutionalism (RCI) and Historical Institutionalism (HI). Arising from the life sciences is now a third: Evolutionary Institutionalism (EI). Comparative strengths and weaknesses of these three theories warrant review, and the value-to-be-added by expanding the third beyond Darwinian evolutionary theory deserves consideration. Should evolutionary institutionalism expand to accommodate new understanding in ecology, such as might apply to the emergence of stability, and in genetics, such as might apply to political behavior? Core arguments are reviewed for each theory with more detailed exposition of the third, EI. Particular attention is paid to EI's gene-institution analogy; to variation, selection, and retention of institutional traits; to endogeneity and exogeneity; to agency and structure; and to ecosystem effects, institutional stability, and empirical limitations in behavioral genetics. RCI, HI, and EI are distinct but complementary. Institutional change, while amenable to rational-choice analysis and, retrospectively, to criticaljuncture and path-dependency analysis, is also, and importantly, ecological. Stability, like change, is an emergent property of institutions, which tend to stabilize after change in a manner analogous to allopatric speciation. EI is more than metaphorically biological in that institutional behaviors are driven by human behaviors whose evolution long preceded the appearance of institutions themselves.

    Traditional translation ethics characterized by translators' ethics cannot provide a strong moral support to the translation practice,or guarantee the moral requirement towards translation activities in the social transformation caused by the market economy,because it does not have the power of punishment.Translation institutional ethics,however,a new form of translation ethics,integrates the translation ethic norm,translation regulations and relative laws together.As an inevitable outcome in the new era,it can escort the orderly and healthy translation activities.Its purpose is to strengthen the translators' moral consciousness,to sublimate their moral notions and to transfer from heteronomy to autonomy.

    Unintentional burn injury is the third most common cause of death in the U.S. for children age 5 to 9, and accounts for major morbidity in the pediatric population. Pediatric burn admission data from U.S. institutions has not been reported recently. This study assesses all pediatric burn admissions to a State wide Certified Burn Treatment Center to evaluate trends in demographics, burn incidence, and cause across different age groups. Demographic and clinical data were collected on 2273 pediatric burn patients during an 18-year period (1995-2013). Pediatric patients were stratified by age into "age 0 to 6," "age 7 to 12," and "age 13 to 18." Data were obtained from National Trauma Registry of the American College of Surgeons and analyzed using standard statistical methodology. A total of 2273 burn patients under age 18 were treated between 1995 and 2013. A total of 1663 (73.2%) patients were ages 0 to 6, 294 (12.9%) were 7 to 12, and 316 (13.9%) were age 13 to 18. A total of 1400 (61.6%) were male and 873 (38.4%) were female (male:female ratio of 1.6:1). Caucasians had the highest burn incidence across all age groups (40.9%), followed by African-Americans (33.6%), P burns occurred at home, P burned was 8.9%, with lower extremity being the most common site (38.5%). Scald burns constituted the majority of cases (71.1%, n = 1617), with 53% attributable to hot liquids related to cooking, including coffee or tea, P burns were the dominant cause (53.8%). Overall mean length of stay was 10.5 ± 10.8 days for all patients, and15.5 ± 12 for those admitted to the intensive care unit, P burn injuries are scald burns that occur at home and primarily affect the lower extremities in Caucasian and African-American males. Among Caucasian teenagers flame burns predominate. Mean length of stay was 10 days, 23% of patients required skin grafting surgery, and mortality was 0.9%. The results of this study highlight the need for primary prevention programs focusing on avoiding

    To evaluate the risk of emergent cesarean delivery with the use of neuraxial anesthesia for external cephalic version in a single practice. Randomized trials have shown increased external cephalic version success when neuraxial anesthesia is used, without additional risk. We hypothesized that in our actual clinical practice, outside the confines of randomized trials, neuraxial anesthesia could be associated with an increased risk of emergent cesarean delivery. This retrospective cohort study included all women who underwent external cephalic version at a single institution with and without neuraxial anesthesia. The primary outcome was the incidence of emergent cesarean delivery (defined as delivery within 4hours of version). Secondary outcomes were version success and ultimate mode of delivery. A total of 135 women underwent external cephalic version procedures; 58 with neuraxial anesthesia (43.0%) and 77 without (57.0%). Location of the procedure, tocolytic therapy, and gestational age were different between groups. An increased rate of emergent cesarean delivery was found in procedures with neuraxial anesthesia compared to procedures without (5/58 (8.6%) compared to 0/77 (0.0%); 95% CI for difference, 1.4 to 15.8%; P=0.013). In this single hospital's practice, patients who may be at higher risk of complications and have a lesser likelihood of success were provided NA for ECV. As a result, the use of neuraxial anesthesia for external cephalic version was associated with a higher rate of emergent cesarean delivery. Obstetric and anesthetic practices should evaluate their patient selection and procedure protocol for external cephalic version under neuraxial anesthesia. Copyright © 2017 Elsevier Ltd.

    Full Text Available Objective This study aimed to assess the clinicoradiological features and treatment outcome of intracranial dissecting aneurysms (IDAs in childhood.Methods We conducted a retrospective study of pediatric patients who were treated for spontaneous IDAs in our institute between January 2010 and December 2015. The clinical presentation, aneurysm characteristics, treatment modality, and outcome were studied. Results We studied 26 pediatric patients (mean age, 13.4 years; range, 4–18 years with 31 IDAs who comprised 6.9% of all IDA patients treated during the same period. Seventeen (65.4% patients were male and nine (34.6% were female. The incidence of large (≥10mm in size or giant aneurysms (≥25mm in size was 65.5%. Twenty-one (80.8% patients underwent endovascular or surgical treatment and five (19.2% received conservative treatment. Perioperative complications occurred in three patients, in whom two eventually recovered completely with a Glasgow Outcome Scale (GOS score of 5 and one partially recovered with a GOS score 4. Overall, 25 (96.2% patients had a favorable outcome and one (3.8% had an unfavorable outcome at a mean follow-up of 22.8 months (range, 6–60 months.Conclusions Pediatric IDAs are rare. In this series, endovascular management was a relatively safe and effective method of treatment for pediatric IDAs. However, continued follow-up is required because of the possibility of aneurysm recurrence and de novo aneurysm formation after treatment.

    Atypical antipsychotics have been associated with weight gain. This study examines the efficacy of adjunctive topiramate in patients with schizophrenia and schizoaffective disorder with antipsychotic-induced weight gain. A 2-year retrospective case analysis was performed in all 300 patients of the outpatient Special Follow-up Clinic for chronic schizophrenia and related psychoses at the Allan Memorial Institute, McGill University Health Centre (Montreal, Canada), a tertiary care University teaching hospital. 10 patients met study inclusion criteria. Mean daily topiramate dose was 197.5 mg (A+/-77) (range, 125-400 mg). Topiramate produced continued weight loss throughout the study duration without tolerance. Patients treated for 6 months and more had significantly higher Body Mass Index (BMI) differences than those treated for shorter durations (BMI-d6 months=-4.7A+/-2.4; BMI-d2 months=-3.2A+/-2.3; P=0.015). BMI changes were similar across genders. This study supports topiramate use to target weight loss in stable overweight schizophrenic patients as a potential therapy that requires further investigation.

    Purpose: To seek for the possible factors influencing overall survival (OS) with radiotherapy (RT) for biliary tract cancer. Materials and methods: Data were collected retrospectively from RT database of 31 institutions in Japan. All patients underwent at least external beam RT. The factors influencing OS were investigated. Results: Data of 498 patients were analyzed. Median OS of the 212 patients who underwent surgery was significantly better than that of the 286 patients without surgery (31 vs. 15 months, p < 0.001). The OS for the R0 or R1 resection group was significantly longer than that for the R2 or non-surgery group, as well as for n0 compared to n1 (all p < 0.001). Chemoradiotherapy (CRT), both sequential and concurrent, resulted in a better OS than RT alone for the n1 group (31 vs. 13 months, p < 0.001), and marginally better for the R0/R1 group (p = 0.065; p = 0.054 for concurrent CRT). However, no such benefit was observed for the R2/non-surgical patients. Multivariate analysis identified performance status, clinical stage, and surgery as significant factors. Conclusion: Surgery, especially R0/R1 resection, seemed as the gold standard for treatment of biliary tract cancer including RT, even in the highly heterogeneous population obtained from the multicenter retrospective study. The possibility was shown that CRT yielded better survival benefit especially for n1 patients. We recommend that future prospective trials include an arm of adjuvant CRT at least for n1 and possibly R0/R1 patients

    Full Text Available Abstract Background We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients. Methods This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates. Results Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68% presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year. Conclusion Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered.

    Background: Male breast cancer incidence rises with age with peak in the sixth and seventh decade. It is one of the rare diseases and accounts for less than 1% of all malignancies worldwide. It is usually diagnosed in the late stage with poor prognosis. Objective: The purpose of this study was to know the demographic pattern and tumour characteristic of breast cancer in men reported at Institute of Radiotherapy and Nuclear Medicine (IRNUM), Peshawar. Methods: Retrospective data was collected from the (IRNUM), Peshawar for a period of three years (2006-2008). The evaluation was done from the histopathological reports of mastectomy and biopsy specimens. All male patients in the age group 26 -86 year with breast cancer were included in the study. The age of the patients and tumour characteristics recorded were size, grade, type, skin involvement and stage. Results: Total number of male patients with breast cancer were 31 (2.1%) out of the total patients with breast malignancy during the study period with the mean age of 58.3 years. Tumour size ranged from 2 to 12 Cm. with average of 3.6 Cm. Invasive ductal carcinoma was found in 87% , papillary carcinoma in 6.5%, each of malignant fibrous histocytoma and sarcoma in 3.2% cases. Maximum number of patients was of grade II (41%). Patients in whom stage of the disease was know n were 22 cases with 45.5% had stage III disease and 32% had stage IV disease. Skin involvement was found positive in 8 (25.8%). Conclusion: Due to poor health care system breast cancer is diagnosed in a late stage of the disease and prognosis is poor. (author)

    We investigated the prevalence of xerostomia in dental patients and built a xerostomia risk prediction model by incorporating a wide range of risk factors. Socio-demographic data, past medical history, self-reported dry mouth and related symptoms were collected retrospectively from January 2010 to September 2013 for all new dental patients. A logistic regression framework was used to build a risk prediction model for xerostomia. External validation was performed using an independent data set to test the prediction power. A total of 12 682 patients were included in this analysis (54.3%, females). Xerostomia was reported by 12.2% of patients. The proportion of people reporting xerostomia was higher among those who were taking more medications (OR = 1.11, 95% CI = 1.08-1.13) or recreational drug users (OR = 1.4, 95% CI = 1.1-1.9). Rheumatic diseases (OR = 2.17, 95% CI = 1.88-2.51), psychiatric diseases (OR = 2.34, 95% CI = 2.05-2.68), eating disorders (OR = 2.28, 95% CI = 1.55-3.36) and radiotherapy (OR = 2.00, 95% CI = 1.43-2.80) were good predictors of xerostomia. For the test model performance, the ROC-AUC was 0.816 and in the external validation sample, the ROC-AUC was 0.799. The xerostomia risk prediction model had high accuracy and discriminated between high- and low-risk individuals. Clinicians could use this model to identify the classes of medications and systemic diseases associated with xerostomia. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    Full Text Available The hand is an instrument extensively used in daily life activities- practical and professional; and it is, consequently, often injured, causing impact on productivity and on the country’s economy, also affecting the quality of life of individuals. When the lesion is work-related, it should be reported and referred by the service unit to Worker Health Reference Centre (CEREST. However, systems of records of occupational accidents are still little explored in Brazil. The aim of this work was to conduct a retrospective data survey on hand traumatic injuries of patients treated at CEREST in the municipality of Jundiaí, Sao Paulo state, in order to know the profile of these victims. Data were collected from the records of SINAN card - Severe Accident Research Sheet, in 2009. Of the 416 cases reported at SINAN, 45.2% were accidents involving the hand, which were reported mostly by private hospitals. 70.7% of the accidents reported occurred in the city (Jundiai and 88.3% of them took place within the premises of companies. Men aged between 19 and 39 years old were the most affected. Machine operators presented the highest accident incidence and fracture was the most frequent diagnosis. Temporary disability reached 80.3% of workers. 89.3% worked under formal contracts. Investment in record systems of labor accidents is essential because it would prevent underreporting and improve awareness of employees and public agencies regarding prevention and rehabilitation, thus avoiding inability of workers and damage to businesses and the government.

    This book is based on some of the lectures during the Pacific Institute of Theoretical Physics (PITP) summer school on "Quantum Magnetism", held during June 2006 in Les Houches, in the French Alps. The school was funded jointly by NATO, the CNRS, and PITP, and entirely organized by PITP. Magnetism is a somewhat peculiar research field. It clearly has a quantum-mechanical basis – the microsopic exchange interactions arise entirely from the exclusion principle, in conjunction with respulsive interactions between electrons. And yet until recently the vast majority of magnetism researchers and users of magnetic phenomena around the world paid no attention to these quantum-mechanical roots. Thus, eg., the huge ($400 billion per annum) industry which manufactures hard discs, and other components in the information technology sector, depends entirely on room-temperature properties of magnets - yet at the macroscopic or mesoscopic scales of interest to this industry, room-temperature magnets behave entirely classic...

    Full Text Available We aimed to evaluate a wide spectrum of clinical features of adult patients with spondyloarthritis (SpA whose initial manifestation was fever, using the Assessment of SpondyloArthritis international Society (ASAS classification criteria.We retrospectively collected the electronic medical records of hospitalized SpA patients who initially presented to the Severance Hospital (Seoul, Korea with fever from January 2010 to May 2016. As a control group, we also recruited one-hundred consecutive patients who were diagnosed with SpA in our outpatient clinic. Clinical features and laboratory findings were compared in two patient groups.There were 26 patients who had fever as initial presentation of SpA (reactive arthritis 50%, undifferentiated SpA 26.9%, ankylosing spondylitis 15.4%, enteropathic arthritis 3.8%, psoriatic arthritis 3.8%. Peripheral SpA was more common in febrile SpA patients than in control SpA patients (65.4% vs 24.0%, p<0.001. Febrile SpA patients were less frequently HLA-B27 positive than control SpA patients (52.2% vs 77.0%, p<0.05. At baseline, systemic inflammatory markers were significantly higher in the febrile SpA patients (white blood cell count, 11.57 vs 7.81 cells/μL, p<0.001; erythrocyte sedimentation rate, 69.2 vs 41.0 mm/h, p<0.001; C-reactive protein, 109.6 vs 15.3 mg/L, p<0.001. The proportion of patients treated with systemic steroids was significantly higher in febrile SpA patients (57.7% vs. 11.0%, p<0.001. The proportion of patients who visited rheumatology specialty was significantly lower in febrile SpA patients than in control SpA patients (7.7% vs 59.0%, p<0.001.Various subgroups of SpA can be presented with fever as an initial manifestation. Febrile SpA patients demonstrated higher systemic inflammation and a lower chance to visit rheumatology in early stage. When evaluating febrile patients with any clinical features of SpA, clinicians are advised to consider performing SpA-focused evaluation including HLA-B27

    Purpose. - Surgery is the treatment of choice for localized uterine sarcomas. We conducted a retrospective study to define prognostic factors. Patients and methods. - We studied 111 cases of patients treated by adjuvant radiotherapy for uterine sarcoma in seven French centers. The median decline was 31 months. We conducted a univariate analysis to identify factors correlated with local recurrence. The statistically significant factors were studied in multivariate analysis by Cox model. Results. - The median dose of external beam radiotherapy was 45 Gy. Forty-three percent of patients had vaginal vault brachytherapy and 21 % chemotherapy. Only 6.3 % of patients had complications of acute grade III and 8.1 % of long-term sequelae of radiotherapy. The survival rate at 5 years was 74.6 %. They noted 12.6 % of isolated locoregional recurrences, against 29.7 % for distant recurrences, 80 % were pulmonary. Factors correlated with the risk of locoregional relapse were menopausal status (P = 0.045) and surgical margins suspicious or not healthy (P = 0.0095). The chemotherapy did not improve overall survival or disease free survival but the numbers were low. Conclusion. - The postoperative radiotherapy provides good local control in this disease. Brachytherapy is sometimes done, but it does not improve local control. Chemotherapy is not a standard localized stage but the rate of metastatic recurrence calls for the development of strategies involving systemic treatment with radiotherapy. (authors)

    Gastric Gist's account for more than half of all gastrointestinal stromal tumors and represent less than 5% of all gastric tumors. The peak age for harboring Gist of the stomach is around 60 years and a slight male preponderance is reported. These tumors are identified by expression of CD117 or CD34 antigen. Symptoms at presentation usually include bleeding, ab¬dominal pain or abdominal mass. Endoscopically, they typically appear as a submucosal mass with or without ulceration and on CT scans an extra gastric mass is usually seen. Complete surgical resection provides the only chance for cure, with only l-2 cm free margins needed. However, local recurrence and/or metastases supervene in almost half the patients treated with surgery alone, even when no gross residual is left. Thereby imatinib mesylate was advocated as an adjuvant to surgery, which appears to have improved disease-free and overall survival. Aim of the Work: The aim of this work was to assess clinico-pathological features of gastrointestinal stromal tumors (GIST) of the stomach and to appraise the results of treatment by surgery in patients treated at the National Cancer Institute (NCI) of Cairo between January 2002 and December 2007. Patients and Methods: Nineteen patients with histologically and immuno-histochemically proven GIST of the stomach were treated by surgery at the NCI during the 6-year study period. Preoperative assessment included detailed history, clinical examination, full laboratory tests, endoscopy, abdominal ultrasound and CT. General medical assessment included chest X-ray, ECG and echocardiography. Results: The patients' age ranged from 26 to 77 years with a median of 51 years. Obvious male/female preponderance was noticed (68.4% to 31.6%). Tumors were located at the upper 1/3 in 42.1%, at the middle 1/3 in 31.6% and at the lower 1/3 in 26.3%. The most common clinical presentation was related to bleeding (hematemesis, melena or anaemia) and was seen in 63.2%. No tumors were

In a retrospective, case-control study, 275 women with Alzheimer’s disease (AD and 276 control patients from a hospital population were enrolled from July 2007 to December 2010. The AD patients presented with later menopause (P < 0.01, lower occurrence of surgical menopause (P < 0.04, reduced hormone-replacement therapy intake (P < 0.0001, and a longer reproductive life span (P < 0.01, compared to controls. No significant differences were found with respect to age at puberty, number of pregnancies, previous abortions, or contraceptive therapy. A higher education level appeared to have a protective role against the risk of developing AD. In women, menopause and hormone-replacement therapy can differentially modulate the clinical manifestations of AD, but these factors do not play a predictive role in its development.Keywords: Alzheimer’s disease, gender, menopause, hormone-replacement therapy, surgical menopause, education

The objective of this study was to evaluate the complications associated with peripherally inserted central catheters (PICCs in a cohort of patients.In this retrospective cohort study, we included all patient carrying PICCs (n = 603 inserted at our institute between October 2010 and December 2013. The main variables collected were medical diagnosis, catheter care, location, duration of catheterization, reasons for catheter removal, complications, and nursing care. Complications were classified as infection, thrombosis, phlebitis, migration, edema, and/or ecchymosis.All patients were treated according to the same "nursing care" protocol. The incidence rate of complications was two cases per 1000 days of catheter duration. The most relevant complications were infection and thrombosis, both with an incidence of 0.17 cases per 1000 days of the total catheterization period. The total average duration of catheterization was 170 days [SD 6.06]. Additionally to "end of treatment" (48.42% and "exitus", (22.53% the most frequent cause of removal was migration (displacement towards the exterior of the catheter (5.80%.PICCs are safe devices that allow the administration of long-term treatment and preserve the integrity of the venous system of the patient. Proper care of the catheter is very important to improve the quality life of patients with oncologic and hematologic conditions. Therefore, correct training of professionals and patients as well as following the latest scientific recommendations are particularly relevant.

    Full Text Available BACKGROUNDS: Fine needle aspiration cytology is an effective modality for diagnosis of breast lesions. Usually male breast lesions are benign and affect the young male. Most common lesion is gynaecomastia. Male breast cancer accounts for a small proportion of breast cancers. Male breast cancer usually presents at an advanced age. OBJECTIVE: The aim of this study was to examine the nature of male breast lesions and to determine the cytomorphologic patterns of these lesions. MET HODS: five year retrospective study was conducted in our institution and in that 112 patients underwent fine needle aspiration cytology of the palpable breast lump after thorough physical examination. The cytological diagnosis was classified as benign, inf lammatory, malignant and others. RESULTS: In 112 male patients diagnosed with breast lesions, the most common lesion was gynecomastia (103/112, 91.9%, followed by breast cancer (6/112, 5.4%, inflammatory (2/112, 1.8% and apocrine metaplasia (01/112, 0.9 %. Gynecomastia was commonly found in male patients less than 40 years of age, while breast cancer is seen in male patients over 40 years of age

    Ingestion of wilted red maple leaves by horses can result in severe hemolytic anemia and methemoglobinemia. Little is known about what factors influence the outcome of red maple leaf toxicosis in horses. Our hypothesis was that physical examination findings, clinicopathologic variables or therapeutic modalities may predict outcome in horses with red maple leaf toxicity. Horses with red maple leaf toxicosis presented to referral hospitals in the southeast region of the United States. A multi-institutional retrospective study was designed to identify factors that predict mortality in horses with red maple toxicosis. Thirty-two horses with red maple toxicosis were identified, 19 of which died. Twenty-nine horses presented with anemia and 24 had clinicopathologic evidence of systemic inflammation. Renal insufficiency was identified in 12/30 (41%) horses. Laminitis (9/28) and colic (13/30) also were identified in horses with red maple toxicosis, but development of these 2 conditions did not have a negative effect on short-term survival. Horses with red maple toxicosis that survived to discharge were likely to have developed pyrexia during hospitalization (P = .030). Horses that were treated with a corticosteroid had a significantly increased likelihood of death (P = .045). There was no significant relationship between initial serum hemoglobin concentration, methemoglobin concentration, or percentage methemoglobin and mortality in this horse series. This study suggests that information obtained on initial examination cannot be used to accurately predict survival in horses with red maple toxicosis, but horses that receive corticosteroids are unlikely to survive.

    To analyze the importance of pre-treatment factors (age, sex, T, N, histological differentiation, site, Hb level, performance status) and to investigate the influence of cigarette smoking and pulmonary and cardiac diseases on treatment outcomes in laryngeal cancer patients. From the year 1989 until May 1995 372 consecutive patients with cancer of the larynx were radically irradiated at the 2nd Teleradiotherapy Department of the Maria Sklodowska-Curie Memorial Cancer Centre and Institute of Oncology in Warsaw (MSCMCC). Pt. characteristics - 88% men, 12% women, age: 29-82 years, stages: T1-20%, T2 -34%, T3 -30%, T4 -16%, lymph node metastases: 27%. Complete response to treatment (CR) - 71% of cases. Loco-regional control after 2 years 52% (T1-T2 - 64%, T3 - T4 - 40%). Early reactions: pain on swallowing, confluent mucositis and moist skin reaction in 69%, 48% and 41 % of cases, respectively. Serious late complications - 19 patients. In a majority of these cases several forms of serious damage were observed. Patients with advanced disease (T3-T4) present a two times higher death risk as compared to patients in earlier stages of the disease (T1-T2). Patients with cervical node metastases also present a two times higher death risk as compared to N0 cases. Patients with performance status 1 or more had a respectively three or four times higher death risk than patients with performance status - 0. No significant influence of sex, histological differentiation, site, hemoglobin level and cigarette smoking, pulmonary and coronary diseases on treatment outcome has been found. The survival curves come down steeply three and more years after treatment completion due to causes other than local failure. The limited number of serious early and late reactions suggests the possibility of a total dose increase. (author)

    Changes in population birth outcomes, including increases in low birthweight or preterm births, have been documented after natural and manmade disasters. However, information is limited following the 2011 Fukushima Daiichi Nuclear Power Plant Disaster. In this study, we assessed whether there were long-term changes in birth outcomes post-disaster, compared to pre-disaster data, and whether residential area and food purchasing patterns, as proxy measurements of evacuation and radiation-related anxiety, were associated with post-disaster birth outcomes. Maternal and perinatal data were retrospectively collected for all live singleton births at a public hospital, located 23 km from the power plant, from 2008 to 2015. Proportions of low birthweight (increased proportions of low birthweight or preterm births in any year after the disaster (merged post-disaster risk ratio of low birthweight birth: 0.98, 95% confidence interval (CI): 0.64–1.51; and preterm birth: 0.68, 95% CI: 0.38–1.21). No significant associations between birth outcomes and residential area or food purchasing patterns were identified, after adjustment for covariates. In conclusion, no changes in birth outcomes were found in this institution-based investigation after the Fukushima disaster. Further research is needed on the pathways that may exacerbate or reduce disaster effects on maternal and perinatal health. PMID:28534840

    Postoperative hematoma is a rare and dangerous complication of cervical spine surgery. The aim of this study was to investigate the incidence and related factors of postoperative hematoma, and to report on 15 cases at our institution over a 6-year period. Fifteen cases of postoperative hematoma were retrospectively identified. We investigated their neurological outcomes, characteristics, and surgical data, and identified risk factors associated with postoperative (PO) hematoma. Patients with hematoma were compared to those with no hematoma, in order to identify risk factors. Retropharyngeal hematomas developed in seven cases and epidural hematomas in eight. The total incidence of postoperative hematoma was 1.2%: 0.5% retropharyngeal hematomas and 0.6% spinal epidural hematomas. At time of onset, the severity of paralysis was assessed as grade B in one case, grade C in six cases, and grade D in eight cases. Risk factors for PO hematoma were: (1) presence of ossification of the posterior longitudinal ligament (OPLL) (Phematoma group and non-hematoma group (P>0.05). Precise preoperative preparation and systematic evaluation are central to successful management of PO hematoma after anterior cervical surgery. Risk factors for PO hematoma include multilevel decompression, OPLL, higher BMI, and longer operation time. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Background Floating knee injuries are usually associated with other significant injuries. Do these injuries have implications on the management of the floating knee and the final outcome of patients? Our study aims to assess the implications of associated injuries in the management and final outcome of floating knee. Methods 29 patients with floating knees were assessed in our institution. A retrospective analysis of medical records and radiographs were done and all associated injuries were identified. The impact of associated injuries on delay in initial surgical management, delay in rehabilitation & final outcome of the floating knee were assessed. Results 38 associated injuries were noted. 7 were associated with ipsilateral knee injuries. Lower limb injuries were most commonly associated with the floating knee. Patients with some associated injuries had a delay in surgical management and others a delay in post-operative rehabilitation. Knee ligament and vascular injuries were associated with poor outcome. Conclusion The associated injuries were quite frequent with the floating knee. Some of the associated injuries caused a delay in surgical management and post-operative rehabilitation. In assessment of the final outcome, patients with associated knee and vascular injuries had a poor prognosis. Majority of the patients with associated injuries had a good or excellent outcome.

    Full Text Available To evaluate the prognostic factors and indexes of a series of 93 patients with breast cancer and brain metastases (BM in a single institution. Treatment outcomes were evaluated according to the major prognostic indexes (RPA, BSBM, GPA scores and breast cancer subtypes. Independent prognostic factors for overall survival (OS were identified. The median OS values according to GPA 0–1, 1.5–2, 2.5–3 and 3.5–4, were 4.5, 9.5, 14.2 and 19.1 months, respectively (p < 0.0001 and according to genetic subtypes, they were 5, 14.2, 16.5 and 17.1 months for basal-like, luminal A and B and HER, respectively (p = 0.04. Using multivariate analysis, we established a new grading system using the six factors that were identified as indicators of longer survival: age under 60 (p = 0.001, high KPS (p = 0.007, primary tumor control (p = 0.05, low number of extracranial metastases and BM (p = 0.01 and 0.0002, respectively and triple negative subtype (p = 0.002. Three groups with significantly different median survival times were identified: 4.1, 9.5 and 26.3 months, respectively (p < 0.0001. Our new grading system shows that prognostic indexes could be improved by using more levels of classification and confirms the strength of biological prognostic factors.

    Full Text Available BACKGROUND Ovarian tumours being second most common gynaecological cancer in India account for 30% of all cancers of female genital tract. Study conducted to determine relative frequencies of various histological types based on WHO classification and their age distribution with particular emphasis on surface epithelial tumours. This study is undertaken to find out the frequency of incidence of different histopathological subtypes with particular emphasis on surface epithelial tumours and age distribution of ovarian tumours in our institute located in coastal Andhra Pradesh. METHODS This is a retrospective study of 100 cases of ovarian neoplasms collected during a period of 3 years from June 2013 to May 2016 from the Department of Pathology, Katuri Medical College and Hospital, Chinakondrupadu, Guntur, A. P, India. The patients attending our hospital are mostly from rural areas around. Paraffin blocks of all 100 ovarian neoplasms retrieved. Complete clinical and radiological findings analysed from our records. RESULTS The tumours are grouped according to the nature of tumour whether benign or borderline or malignant according to cell of origin, histological subtyping, and age group. Surface epithelial tumours are the most common. Benign tumours outnumber the malignant tumours. Benign ovarian tumours showed a peak in 21-40 Yrs. age group and malignant in the age group of 41- 60 Yrs. Results of our study compared with other studies. CONCLUSION Because of the geographic location, poverty, and illiteracy, patients seek medical advice late. So, awareness among public by health education, passive surveillance, and community screening facility will be helpful in early detection of ovarian neoplasms.

    Full Text Available Objective: The aim of this study was to review cases of odontogenic tumors diagnosed in two pathology centers in Tehran, Iran, during a 10-year period. Study Design: Patients′ records were seen at two teaching pathology Centre′s of Shahid Beheshti University between the months of March 2000 to 2010 with histologic diagnosis of any type of odontogenic tumors. The records were analyzed for frequency, age, sex, site, as well as clinical, radiographic and histopathologic findings. Results: Of 30706 biopsies, 4767 (15.5% cases were diagnosed as oral and maxillofacial lesions. Among these, 720 cases were tumoral with 188 (26.1% cases of odontogenic tumors. Tumors with odontogenic epithelium origin formed 70.2% of total numbers of odontogenic tumors. Mixed odontogenic tumors and tumors of odontogenic ectomesenchyme comprised 12.2% and 17.5% of the cases respectively. Ameloblastoma, with a frequency of 62.2% was the most common tumor in this review which was followed by odontoma and odontogenic myxoma. Conclusion: Although there are few studies on odontogenic tumors in literature, the comparison of our results with existing data shows significant differences in the distribution of tumors and age of patients, which may be due to ethnic features and geographic distribution of patients. Future studies on other ethnic groups are essential for further clarification of the findings in this research.

    2010-01-01

    Purpose: To investigate the efficacy of 3.0-T magnetic resonance imaging (MRI) for detecting brain metastases for stereotactic radiosurgery (SRS) planning. Methods and Materials: All adult patients scheduled for SRS treatment for brain metastases at our institution between October 2005 and January 2008 were eligible for analysis. All patients underwent radiosurgery treatment planning 3.0-T MRI on the day of scheduled radiosurgery and a diagnostic 1.5-T MRI in the days or weeks prior to radiosurgery for comparison. Both scans were interpreted by neuroradiologists who reported their findings in the radiology reports. We performed a retrospective review of the radiology reports to determine the number of brain metastases identified using each MRI system. Results: Of 254 patients scheduled for treatment from October 2005 to January 2008, 138 patients had radiology reports that explicitly described the number of metastases identified on both scans. With a median interval of 17 days (range, 1-82) between scans, the number of metastases detected using 1.5-T MRI system ranged from 1 to 5 and from 1 to 8 using the 3.0 T-MRI system. Twenty-two percent of patients were found to have a greater number of metastases with the 3.0 T-MRI system. The difference in number of metastases detected between the two scans for the entire cohort ranged from 0 to 6. Neither histology (p = 0.52 by chi-sq test) nor time between scans (p = 0.62 by linear regression) were significantly associated with the difference in number of metastases between scans. Conclusions: The 3.0-T MRI system appears to be superior to a 1.5-T MRI system for detecting brain metastases, which may have significant implications in determining the appropriate treatment modality. Our findings suggest the need for a prospectively designed study to further evaluate the use of a 3.0 T-MRI system for stereotactic radiosurgery planning in the treatment of brain metastases.

    Previous studies have suggested that the use of mesh in groin hernia repair may be associated with an increased risk for male infertility as a result of inflammatory obliteration of structures in the spermatic cord. In a recent study, we could not find an increased incidence of involuntary childlessness. The aim of this study was to evaluate this issue further. Men born between 1950 and 1989, with a hernia repair registered in the Swedish Hernia Register between 1992 and 2007 were cross-linked with all men in the same age group with the diagnosis of male infertility according to the Swedish National Patient Register. The cumulative and expected incidences of infertility were analyzed. Separate multivariate logistic analyses, adjusted for age and years elapsed since the first repair, were performed for men with unilateral and bilateral repair, respectively. Overall, 34,267 men were identified with a history of at least 1 inguinal hernia repair. A total of 233 (0.7%) of these had been given the diagnosis of male infertility after their first operation. We did not find any differences between expected and observed cumulative incidences of infertility in men operated with hernia repair. Men with bilateral hernia repair had a slightly increased risk for infertility when mesh was used on either side. However, the cumulative incidence was less than 1%. Inguinal hernia repair with mesh is not associated with an increased incidence of, or clinically important risk for, male infertility. Copyright © 2012 Mosby, Inc. All rights reserved.

    Salivary gland tumours are an important part of the Oral and Maxillofacial Pathology, unfortunately, only few studies on these tumours have been done in Latin-American population. The aim of this study was to compare demographic data on salivary gland tumours in a Mexican sample with those previously published from Latin American and non-Latin American countries. All cases of salivary gland tumours or lesions diagnosed in our service were reviewed. Of the reviewed cases,67 were confirmed as salivary gland tumours. Out of these 64.2% were benign neoplasms, 35.8% were malignant and a slight female predominance (56.7%) was found. The most common location was palate followed by lips and floor of the mouth. Mean age for benign tumours was 40.6 years with female predominance (60.5%). Mean age for malignant tumours was 41 years and female predominance was found again. Palate followed by retromolar area were the usual locations. Pleomorphic adenoma (58.2%), mucoepidermoid carcinoma (17.9%) and adenoid cystic carcinoma (11.9%) were the more frequent neoplasms. All retromolar cases were malignant and all submandibular gland tumours were benign. We found a high proportion of salivary gland neoplasms in children. Our results showed that differences of the studied tumours among our sample and previously reported series exist. These differences can be related to race and geographical location.

    Full Text Available The article is devoted to the neo-institutional approach as a methodological basis in the study of electronic government. In this article substantiates the choice of neo-institutional approach to the study of the processes of implementation of information and communication technologies in the activity of state institutions, analyzes the differences of neoinstitutionalism from traditional institutional approach, considers the features of the different directions of neo-institutionalism, namely sociological, historical and rational choice theory. Attention is paid to the reasons for the renewed interest in political institutions in political science. The article emphasizes the importance of considering the electronic government as an institution, and the conditions for its implementation in the Russian political system as the institutional environment. The authors pay special attention to the variety of sociological neo-institutionalism, used, in addition to political science in sociology of organizations. The article substantiates the value of using sociological institutionalism to explore the electronic government based on a comparative analysis of e-government projects in Russia and abroad and explores its heuristic capabilities. It examines the impact of the system of norms and values of the institutional environment on the processes of formation and development of electronic government in Russia. The research capacity of this theory is due to the fact that it allows us to trace the reasons for copying and replication of inefficient practices and organizational and management schemes, to identify the factors impeding innovation use by the state of electronic interaction technologies. It is emphasized that the use of the theory of institutional isomorphism is useful in the sphere of implementation of electronic technologies, in which a key role play pluralism, horizontal managerial communication, inter-agency coordination.

    Purpose: To present, analyze, and discuss results of a nationwide, multicenter, retrospective study on high-dose-rate brachytherapy (HDR-BT) as monotherapy for low-, intermediate-, and high-risk prostate cancer. Methods and Materials: From 1995 through 2013, 524 patients, 73 (14%) with low-risk, 207 (40%) with intermediate-risk, and 244 (47%) with high-risk prostate cancer, were treated with HDR-BT as monotherapy at 5 institutions in Japan. Dose fractionations were 27 Gy/2 fractions for 69 patients (13%), 45.5 Gy/7 fractions for 168 (32%), 49 Gy/7 fractions for 149 (28%), 54 Gy/9 fractions for 130 (25%), and others for 8 (2%). Of these patients, 156 (30%) did not receive androgen deprivation therapy, and 202 patients (39%) did receive androgen deprivation therapy <1 year, 112 (21%) for 1-3 years, and 54 (10%) for >3 years. Median follow-up time was 5.9 years (range, 0.4-18.1 years), with a minimum of 2 years for surviving patients. Results: After 5 years, respective actuarial rates of no biochemical evidence of disease, overall survival, cause-specific survival, and metastasis-free survival for all patients were 92%, 97%, 99%, and 94%. For low/intermediate/high-risk patients, the 5-year no biochemical evidence of disease rates were 95%/94%/89%, the 5-year overall survival rates were 98%/98%/94%, the 5-year cause-specific survival rates were 98%/100%/98%, and the 5-year metastasis-free survival rates were 98%/95%/90%, respectively. The cumulative incidence of late grade 2 to 3 genitourinary toxicity at 5 years was 19%, and that of late grade 3 was 1%. The corresponding incidences of gastrointestinal toxicity were 3% and 0% (0.2%). No grade 4 or 5 of either type of toxicity was detected. Conclusions: The findings of this nationwide, multicenter, retrospective study demonstrate that HDR-BT as monotherapy was safe and effective for all patients with low-, intermediate-, and high-risk prostate cancer.

    Rhizarthrosis, or osteoarthritis of the base of the thumb, is a common condition affecting 10-30% of the population over the age of 60. Whether it is an occupational disease has been the subject of debate as epidemiological studies on the correlation between physical stress and the presence of rhizarthrosis have shown conflicting results. To study the correlation between the prevalence of rhizarthrosis and the time spent by employees manually processing banknotes at the National Bank of Belgium (NBB). We followed NBB employees currently or previously holding job titles involving the manual or automated processing of banknotes. Each participant's job history was carefully reconstructed and the number of months holding certain job titles determined. Each participant was clinically and radiologically examined for the presence of rhizarthrosis in both hands. Its presence was scored by a combination of clinical and radiological criteria. There were 195 participants. The prevalence of rhizarthrosis was 27% in women (mean age: 52.3 ± 4.4 years) and 17% in men (mean age: 53.2). The odds ratio (OR) for rhizarthrosis after 10 years' full-time overall exposure was significantly higher [OR 10 years: 1.53 (1.03-2.28)]. However, one particular job, 'manual counting', described by participants as highly straining and severely taxing on the thumbs, did not show a significantly higher prevalence of rhizarthrosis. Our study confirmed the correlation between the presence of rhizarthrosis and age, gender and general manual labour, in particular banknote processing, but found no link with one specific job-manual counting. © The Author 2017.

    Full Text Available Background and Objectives: Various extraction protocols have been followed for successful orthodontic treatment. The purpose of this study was to evaluate the extraction protocols in patients who had previously undergone orthodontic treatment and also who had reported for continuing orthodontic treatment from other clinics. Materials and Methods: One hundred thirty eight patients who registered for orthodontic treatment at the Faculty of Dentistry were divided into 10 extraction protocols based on the Orthodontic treatment protocol given by Janson et al. and were evaluated for statistical significance. Results: The descriptive statistics of the study revealed a total of 40 (29% patients in protocol 1, 43 (31.2% in protocol 2, 18 (13% in protocol 3, 16 (11.6% in protocol 5, and 12 (8.7% in Type 3 category of protocol 9. The Type 3 category in protocol 9 was statistically significant compared to other studies. Midline shift and collapse of the arch form were noticed in these individuals. Conclusion: Extraction of permanent teeth such as canine and lateral incisors without rational reasons could have devastating consequences on the entire occlusion. The percentage of cases wherein extraction of permanent teeth in the crowded region was adopted as a treatment option instead of orthodontic treatment is still prevalent in dental practice. The shortage of orthodontists in Malaysia, the long waiting period, and lack of subjective need for orthodontic treatment at an earlier age group were the reasons for the patient's to choose extraction of the mal-aligned teeth such as the maxillary canine or maxillary lateral incisors.

We undertook a retrospective chart review and tested the hypothesis that tidal volume is a predictor of mortality in cardiothoracic (medical and surgical critical care patients receiving invasive mechanical ventilation. Independent predictors of mortality in our study included: type of surgery, albumin, H+, bilirubin, and fluid balance. In particular, it is important to note that cardiac, thoracic, and transplant surgical patients were associated with lower mortality. However, our study did not sample equally from The Berlin Definition of ARDS severity categories (mild, moderate, and severe hypoxemia. Although our study was not adequately powered to detect a difference in mortality between these groups, it will inform the development of a large prospective cohort study exploring the role of low tidal volume ventilation in cardiothoracic critically ill patients.

    Full Text Available The study described perceived differences in the choice of child rearing practices aimed at correcting children’s inappropriate behaviors as remembered by the participants at young adulthood. The sample consisted of 207 students of under-graduate studies of the University of Novi Sad. The most of the participants does not have children and they grew up in complete families. On the Dimensions of Discipline Inventory (A (DDI-A, Straus, Fauchier, 2007, the participants estimated the experience and methods of disciplining which were used by their parents during their childhood. The participants describe uniform discipline behaviors of their parents regarding the estimated discipline techniques. These behaviors are dominated by the punishing ones, and the differences between fathers and mothers are visible in a stronger tendency to describe fathers as the ones who use corporal punishment, abolish privileges and give restorative tasks. The described discipline techniques for both fathers and mothers remain stable and similar, regardless of the socio-demographic characteristics of the families as family completeness, work experience and level of education of the parents, as well as estimated economic status of the family.

    Full Text Available Numerous etiologies are responsible for cases of stroke in young adults. This study reviews the causes of two types of stroke (ischemic and intracerebral hemorrhage in young adults aged 15 to 40years, admitted to our center (a tertiary care center from 1997 to 2002. The purpose of this study is to determine the relative frequency of causes of stroke in young adults and compare this with published data in the literature. Using the codes 46.0 to 46.8 of the International Classification of Diseases- 10th Edition (ICD-10, cases were identified from the records of the stroke patients admitted in Imam Khomeini Hospital and the data were collected from their files using a comprehensive questionnaire. Forty-two cases of ischemic stroke (62% and 26 cases of intracerebral hemorrhage (38% were identified. The leading cause of ischemic stroke was cardioembolism (38.1%, followed by atherosclerosis in 5 cases (11.9%. Among cardiac causes infarction was attributable to consequences of rheumatic heart disease in 8 cases. In 3 cases a cessation or decrease in dose of warfarin was followed directly by an ischemic stroke. The most leading cause of intracerebral hemorrhage was hypertension (30.8%. Other causes were anticoagulant therapy, intratumoral hemorrhage, aplastic anemia, leukemia, arteriovenous malformations, and chronic active hepatitis. In conclusion, cardioembolism and hypertension were the most leading causes of ischemic and hemorrhagic stroke in young adults admitted in our hospital.

    Suicide is one of the ten leading causes of death in the world, accounting for more than a million deaths annually. The purpose of the study was to identify the risk groups. In the four-year period from January 2000 to December 2003, 588 suicide victims were autopsied. Information was obtained by interviewing the acquaintances of the victim, perusal of hospital records and the autopsy findings. All the cases were analyzed as to sex, age, and methods of suicide, seasonal variation, diurnal variation and other sociological aspects. The present study depicts a suicidal rate of 11.76 per 100,000 population. Males and females were almost equally the sufferers. The largest number of victims were found in the age group of 21-30 years. Hanging and poisoning constituted the two major modes of suicides (63%). Majority of the victims were mentally sound, married and were from rural background. Victims were mostly drawn from low socioeconomic status (48%). Less educated or illiterates were usually the victims. Suicidal note was detected in 5% of cases. Suicidal tendency and alcohol intake could not be encountered in most of the cases. Indoor incidence was almost double of the outdoor incidence, mostly seen in rainy season (43%) and occurred almost equally during day and night. Financial burden (37%) and marital disharmony (35%) were the principal reasons for the suicide.

    The study aimed at determining the association between oral disease and systemic health based on panoramic radiographs and general health of patients treated at Kuwait University Dental Center. The objective was to determine whether individuals exhibiting good oral health have lower propensity to systemic diseases. A total of 1000 adult patients treated at Kuwait University Dental Center were randomly selected from the patient's records. The general health of patients was assessed from the medical history of each patient recorded during their visit to the clinic. The number of reported diseases and serious symptoms were used to develop a medical index. The oral health of these patients was assessed from panoramic radiographs to create an oral index by evaluating such parameters as caries, periodontitis, periapical lesions, pericoronitis, and tooth loss. In a total of 887 patients, 43.8 % had an oral index between 3 and 8, of which significantly higher (62.1 %) patients were with medical conditions compared to those without (33.2 %; p relationship when the diagnosis of oral disease was based primarily on radiographic findings. Future research needs to include prospective clinical and interventional studies. The significance of the oral-systemic disease connection highlights the importance of preventing and treating oral disease which have profound medical implications on general health.

    The aim of this paper was to ascertain chronic obstructive pulmonary disease (COPD) prevalence among industrial workers in the Russian Federation and determine relative contribution of smoking and occupational factors to COPD. We recruited 1,375 workers aged 30 or over. Six hundred and twenty-four of them were occupationally exposed to vapours, gases, dust, and fumes (VGDF). Physical examination and baseline spirometry were performed for all the participants of the study. Those with airfl ow limitation of FEV1/FVC<0.70 were considered having COPD and those with presence of cough and sputum production for at least three months in each of two consecutive years were considered having chronic bronchitis (CB), with no overlapping between these 2 groups. Data on occupational history and VGDF levels in the working area were collected from all participants. In total, 105 cases of COPD and 170 cases of CB were diagnosed in the cohort of examined workers. Occupational exposure to VGDF was twice as often present among COPD patients than among both patients with CB and the control group of healthy workers (p<0.05). More than 40 % of COPD patients were occupationally exposed to VGDF above the value of 3.0 of the occupational exposure limit (OEL) and more than 20 % to 6.0 OEL and higher. Overall odds ratio for COPD development due to occupational VGDF exposure was 5.9 (95 % CI=3.6 to 9.8, p=0.0001). Both smoking and VGDF seem to be important for the development of COPD. Analysis of the combined effect of tobacco smoking and occupational noxious particles and gases on COPD development has shown the following order of risk factors based on the strength of their infl uence: VGDF levels, smoking index, age, and heating microclimate. There is a statistically signifi cant level of relationship and "dose-effect" dependence between occupational exposures to VGDF and the development of COPD. The effect of VGDF composition on the probability of COPD development was not found in the study

    The purpose of the present study was to assess the number of pathological dental changes and anomalies in dogs. The incidence of dental diseases was investigated in radiologically examined 139 males and 120 females, aged from 7 months to 15 years. The incidence of oligodontia equalled to 45.17 %, peridontitis 44.40 %, fracture 19.30 %, tooth rotation 11.5 %, persisting deciduous teeth 5.40 % and supernumerary teeth 3.86 %. Incidence of dental changes and anomalies differed significantly between dogs of different age groups. Considering the hereditary nature of the anomalies such as congenital oligodontia, tooth rotation and retained deciduous teeth, dog breeders should provide for a timely X-ray examination and, in case of these anomalies, exclude the affected dogs from further breeding

    Full Text Available The spleen of dogs is frequently affected by disorders that vary from local and systemic origin. The difficulty in associating clinical and gross findings contributes for the choice of total splenectomy as the main treatment, leading to an impairment of the immune and hematopoietic functions. The aim of this study was to evaluate the pathological findings in the spleen of splenectomized dogs during 2008 to 2014 at a Veterinary Teaching Hospital. From the 71 cases analyzed, 97% (69/71 of the dogs were submitted to total splenectomy and 3% (2/71 to partial splenectomy. In 45 (63.4% of these cases, the histopathological diagnosis was non-neoplastic alterations; only 36.6% (26/71 had a splenic neoplasia. The main non-neoplastic lesions observed were nodular hyperplasia 24.4% (11/45, infarction 22.3% (10/45, and hematoma 20% (9/45. The most frequent tumors were hemangiosarcoma 50% (13/26, histiocytic sarcoma 23% (6/26, and lymphoma 11.5% (3/26. The clinical methods used to diagnose splenic lesions were ultrasonography 88% (63/71, radiography 2.8% (2/71 and exploratory laparotomy 4.2% (3/71. In 4.2% (3/71 the spleen changes were observed during the therapeutic ovariohysterectomy. The results of the present study showed a prevalence of benign disorders in the spleen of splenectomized dogs associated with a high incidence of total splenectomy performed, indicating a difficulty in recognizing the different lesions that can affect the spleen by the veterinarian medical.

    Full Text Available Abstract Background Relations between maxillo-mandibular deformities and TMJ disorders have been the object of different studies in medical literature and there are various opinions concerning the alteration of TMJ dysfunction after orthognathic surgery. The purpose of the present study was to evaluate TMJ disorders changes before and after orthognathic surgery, and to assess the risk of creating new TMJ symptoms on asymptomatic patients. Methods A questionnaire was sent to 176 patients operated at the Maxillo-Facial Service of the Lille's 2 Universitary Hospital Center (Chairman Pr Joël Ferri from 01.01.2006 to 01.01.2008. 57 patients (35 females and 22 males, age range from 16 to 65 years old, filled the questionnaire. The prevalence and the results on pain, sounds, clicking, joint locking, limited mouth opening, and tenseness were evaluated comparing different subgroups of patients. Results TMJ symptoms were significantly reduced after treatment for patients with pre-operative symptoms. The overall subjective treatment outcome was: improvement for 80.0% of patients, no change for 16.4% of patients, and an increase of symptoms for 3.6% of them. Thus, most patients were very satisfied with the results. However the appearance of new onset of TMJ symptoms is common. There was no statistical difference in the prevalence of preoperative TMJ symptoms and on postoperative results in class II compared to class III patients. Conclusions These observations demonstrate that: there is a high prevalence of TMJ disorders in dysgnathic patients; most of patients with preoperative TMJ signs and symptoms can improve TMJ dysfunction and pain levels can be reduced by orthognathic treatment; a percentage of dysgnathic patients who were preoperatively asymptomatic can develop TMJ disorders after surgery but this risk is low.

    Full Text Available Background: Gestational trophoblastic disease (GTD defines a heterogenenous group ofinterrelated lesions that arise from the trophoblastic epithelium of the placenta. There are severalhistologically distinct types of GTD: hydatiform mole (complete or partial, persistant/invasivegestational trophoblastic neoplasia (GTN, choriocarcinoma and placenta site trophoblastictumors. The aim of this study was to determine the frequency and risk factors of GTD amongwomen admitted to Imam Khomeini Hospital in Ahvaz, Iran.Materials and Methods: This was a cross-sectional study conducted at Imam KhomeiniHospital in Ahvaz, Iran. All hospital records related to GTD (132 from 1996 until 2006 werereviewed. Demographic and histo-pathologic characteristics were extracted. Chi-square andFisher-exact tests were used to analyze all variables. P ≤ 0.05 was considered statisticallysignificant. SPSS, version 11 was used for statistical analysis.Results: The mean age of patients was 27.6 years. Most patients who presented with GTDwere of ages 18-35 years (71.3%. There was no relationship between age and hydatiformmole during the reproductive years. There were 28 (18.9% patients over the age 40, of which18 (15.90% of these had a complete hydatiform mole. Within this group, 9 (6.8% changedto a persistent mole. There was a significant relationship between age over 40 and completemole (p<0.02. The percentage of patients with blood groups A and O was the same (37.9%.There was a significant relationship between blood groups (O+ and A+ and complete mole(p<0.05.Conclusion: The most common age range for hydatiform mole was 18-35 years. Women overthe age of 40 had a more complete hydatiform mole, which is similar to the other countries.Age and blood group are two risk factors for hydatiform mole.

Demographic, clinical, investigative and treatment data were collected using a pre-set proforma. 138 (12.1%) of the total 1143 leprosy cases registered for treatment during the 10-year period were below 15 years of age. The 10-year study period witnessed a statistically insignificant decrease in the new childhood leprosy cases registered for treatment in our tertiary care institution. The majority of cases belonged to the 6-12 year age group (61.6%) with a male predominance. Borderline tuberculoid (BT) was the commonest clinical type (65.9%) followed by indeterminate leprosy (18.8%); 101 patients required paucibacillary (PB) and 37 needed multibacillary (MB) treatment. The number of patients requiring MB treatment showed a statistically significant increase and there was a significant decline in number of cases requiring PB treatment. During the entire study period no Type 2 lepra reaction was documented in patients below Hema 15 years and only two patients manifested Type 1 reaction. Ten (7.2%) out of the 138 patients were cases of relapse. There was a clear female predilection among relapse cases with the majority belonging to the adolescent age. Childhood leprosy still contributes to a significant proportion of the total case load denoting the continuing active horizontal transmission of leprosy. The rise in number of patients with more extensive disease in the background of declining disease prevalence is suggestive of the delay in diagnosis and treatment. A high

    Full Text Available BACKGROUND Leukaemias are biologically a diverse group of disorders with differences in their morphology, antigen expression, chromosomal and molecular abnormalities, response to treatment, and prognosis. The main objective of the study was to compare morphological and flowcytometric diagnosis in patients diagnosed with acute leukaemia. MATERIALS AND METHODS The prospective study was carried out at S.C.B. Medical College and hospital, Cuttack, in department of Pathology and Clinical haematology, for the period of November 2015- November 2017. The findings were based on 100 patients who underwent both flow cytometry and peripheral smear/bone marrow morphology tests for diagnosis of acute leukaemia. RESULTS Using the peripheral smear/bone marrow morphology, 27% patients had ALL-L1, 38% had ALL-L2, 05% had AML-M1, 21% had AML-M2, 06% had AML-M3, 02% had AML-M4, and 01% had AML-M5. Immunophenotyping by flow cytometry confirms 50% patients to be B-ALL, 07% to be T-ALL, 32% AML, 08% APML/AML-M3, and 03% to be MPAL. There was a concordance between the morphological and flowcytometry of 88% in ALL, 91% in AML, 75% in APML, but, no concordance at all for MPAL. CONCLUSION Hence, flowcytometry is mandatory in all cases of acute leukemia, to confirm a definite diagnosis, as treatment nowadays is target oriented.

    Over 50% of cancer patients suffer from insomnia, nearly twice the estimated prevalence in the general population. However, this widespread problem has received far less attention compared to cancer pain and fatigue. The aim of this study was to determine whether certain factors can alter the sleep-wake cycle in this patient subgroup and whether altered nyctohemeral sleep rhythms may negatively impact on quality of life. The medical records of 101 patients treated at the Cancer Center, San Giovanni Battista Hospital, Turin, and who had died of cancer in 2007, were reviewed. Extracted from each record were data on: patient age, sex, primary tumor site, presence of pain, concomitant conditions, concomitant medications, type of therapy, chemotherapeutic (CT) scheme, survival, and side effects. The sample was divided into two subgroups defined as inducers or non-inducers, depending on whether the patient had taken medications or not to treat insomnia. Significant differences between the two groups for these variables were tested using statistical analysis. A statistically significant difference between the two groups emerged for anxiety-depression syndromes (P=0.00001), the number of sleeping pills taken in association with a concurrent anxiety-depression syndrome (P=0.01463), and side effects (P=0.0015). There was a statistically significant difference between the inducer and the non-inducer groups for female sex (one-tailed Fisher's exact test; P=0.04170) but the difference was marginal on Fisher's two-tailed test (P=0.06121). No statistically significant differences between the two groups were found for mean age (P=0.61281), median age (P=0.9996), primary tumor site, concomitant conditions (P=0.4205), survival (P=0.5704), presence of pain (P=0.53300) or type of therapy (P=0.6466). Sleep disturbances are a common complaint of cancer patients but have only recently attracted greater attention as the diagnosis of cancer has increased. Sleep disturbances are not an

    The United Arab Emirates is a rapidly developing country with recent expansion in construction and manufacturing. To investigate the occurrence and outcomes following occupational traumatic brain injury (TBI) requiring hospital admission. Records for all TBI cases admitted to an Abu Dhabi hospital between 2005 and 2009 were reviewed. Data on mechanisms of occupational injuries, Glasgow Coma Scale (GCS) on admission and Glasgow Outcome Scale (GOS) on follow-up, were analysed. Of 581 TBI cases reviewed, 56 (10%) cases were reported as occupational by either the patient or the informant accompanying the patient. All cases were male migrants, and 63% were aged 25-44. Falls accounted for 63% of cases, falling objects 34% and motor vehicle collisions 4%. Median GCS score was 13 for all cases. Median hospital stay was 7.5 days. Intensive care unit admission data were available in 47 cases, of which 34% (16) were admitted with a median stay of 5 days. GOS data were available in 95% (53) of cases, with good recovery in 81% cases, moderate-to-severe disability in 11% of cases and death in 8% (4) cases. Occupational TBI requiring hospitalization is most frequently due to falls and falling objects, with potentially grave consequences. This study further highlights the urgent need to implement preventative measures to improve construction worker safety.

    The object of this study was to evaluate hypofractionated multiportal field and two-portion (rostral and caudal portions divided by the eyelid) radiation therapy for canine nasal tumors. Sixty-three dogs underwent multiportal hypofractionated radiation therapy. The radiation field was divided into rostral and caudal portions by the eyelid. Treatments were performed four times for 57 dogs. The median irradiation dose/fraction was 8 Gy (range, 5-10 Gy); the median total dose was 32 Gy (10-40 Gy). Improvement of clinical symptoms was achieved in 53 (84.1%) of 63 cases. Median survival time was 197 days (range, 2-1,080 days). Median survival times with and without destruction of the cribriform plate before radiotherapy were 163 and 219 days, respectively. There was no significant difference between them. No other factors were related to survival according to a univariate analysis. All radiation side effects, except one, were grade I according to the VRTOG classification. It was not necessary to treat any dogs for skin side effects. One dog (1.6%) developed an oronasal fistula 1 year after completion of radiation therapy. This radiation protocol may be useful in reducing radiation side effects in dogs with cribriform plate destruction. (author)

    The purpose of this study was to assess the mortality and risk factors of complications after pneumonectomy for lung cancer. Between 1996 and 2001, we reviewed and analysed the demographic, clinical, functional, and surgical variables of 168 patients to identify risk factors of postoperative complications by univariate and multivariate analyses with Medlog software system. The mean age was 60+/-10 years, overall mortality and morbidity rates were 4.17% and 41.6%, respectively. All frequencies of respiratory complications were 1.2% for acute respiratory failure, 10.1% for pneumonia, 2.4% for acute pulmonary oedema, 4.17% for bronchopleural fistula, 2.4% for thoracic empyema and 18.5% for left recurrent nerve injuries. Postoperative arrhythmias developed in 46% of our patients. The risk factors for cardiopulmonary morbidity and mortality with univariate analysis were advanced age (P<0.01), preoperative poor performance status (P<0.015), and chronic artery disease (P<0.008). Factors adversely affecting morbidity with multivariate analysis included age (P=0.0001), associated cardiovascular disease (P=0.001), and altered forced expiratory volume in 1 s (P=0.0005). Complications after pneumonectomy are associated with high mortality. Careful attention must be paid to patients with advanced age and heart disease. Chest physiotherapy is paramount to have uneventful outcomes.

    Full Text Available Background. Central venous catheter (CVC related infection is associated with significant increases in morbidity, mortality, and health care cost.This local surveillance study was carry out to monitor the frequency of occurrence of CVC-related blood stream infections. Materials and methods. During the period January – December 2005, 226 CVC specimens were analyzed (quantitative method and microrganism identification from positive samples was performed by Vitek II. In 53 patients it was possible to compare quantitative results with those obtained from blood cultures. Results. Positive CVC samples were 125 (55% and 130 microrganisms were isolated: 109 Gram-positives (84%, 4 Gram-negatives (3%, and 17 mycetes (13%. Among pathogens collected simultaneously from CVC and blood samples, the most frequently isolated were Staphylococcus spp. (30% coagulase-negative staphylococci and 20%. S. aureus and Candida spp. (45%. In the group of patients that presented positive CVC and negative blood samples the most frequently recovered microrganisms were staphylococci. Many isolates (33% were polymicrobial. Conclusions. Catheter-related infections occurred in those patients who presented the same pathogen in both CVC and blood cultures. These infections were principally caused by staphylococci and Candida spp. On the contrary, a possible CVC contamination could be suspected when positive CVC and negative blood cultures were found.

    During the last decade we have been witness to several exciting achievements in electron crystallography. This includes structural and charge density studies on organic molecules complicated inorganic and metallic materials in the amorphous, nano-, meso- and quasi-crystalline state and also development of new software, tailor-made for the special needs of electron crystallography. Moreover, these developments have been accompanied by a now available new generation of computer controlled electron microscopes equipped with high-coherent field-emission sources, cryo-specimen holders, ultra-fast CCD cameras, imaging plates, energy filters and even correctors for electron optical distortions. Thus, a fast and semi-automatic data acquisition from small sample areas, similar to what we today know from imaging plates diffraction systems in X-ray crystallography, can be envisioned for the very near future. This progress clearly shows that the contribution of electron crystallography is quite unique, as it enables to r...

    Objective To determine the natural course of cluster headache. Methods We screened patients with cluster headache who were diagnosed at Samsung Medical Center and lost to follow-up for ≥5 years. Eligible patients were interviewed by phone about the longitudinal changes in headache characteristics and disease course. Remission was defined as symptom-free 1) for longer than twice the longest between-bout period and 2) for ≥5 years. Results Forty-two patients lost to follow-up for mean 7.5 (range, 5.0-15.7) years were included. The length of the last bout did not differ from the first one, while the last between-bout period was longer than the first one ( p = 0.012). Characteristics of cluster headache decreased over time: Side-locked unilaterality (from 92.9% to 78.9%), seasonal and circadian rhythmicity (from 63.9% to 60.9% and from 62.2 to 40.5%, respectively), and autonomic symptoms (from 95.2% to 75.0%). Remission occurred in 14 (33.3%) patients at a mean age of 42.3 (range, 27-65) years, which was not different from the age of last bouts in active patients ( p = 0.623). There was a trend for more seasonal and circadian predilection at baseline in the active group ( p = 0.056 and 0.063, respectively) and fewer lifetime bouts and shorter disease duration in patients in remission ( p = 0.063 and 0.090). Conclusions This study first shows the natural courses of cluster headache. Features of cluster headache become less prominent over time. Remission occurred regardless of age. Although no single predictor of remission was found, our data suggest that remission of cluster headache might not be a consequence of more advanced age, longer duration of disease, or accumulation of lifetime bouts.

    From 1977 to 1983, 83 patients (pts) with 87 facial skin carcinomas (FSC) were treated with interstitial brachytherapy (BT) in our department. Median age was 70 years (43-97 y). There was 61 basal cell carcinomas and 26 squamous cell carcinomas. 28 of them corresponded to local relapse of FSC initially treated without BT. TNM stadification was as following: T1+rT1=72,4%; T2+rT2=23%; T3+rT3=2,3%; T4+rT4=2,3%. The median follow-up was 53 months (8 months to 15 years). Different techniques were used:hypodermic needles,plastic tubes, Raynal method. A dose of 60 Gy was prescribed on the reference isodose, according to the PARIS system. Specific overall survival was 98,8% at 5 and 10 y. Local control at 5 and 10 y was 100 and 90% for FSC treated in first intention, and 81,2% for recurrent FSC. This was highly significant (p=0,002 Logrank test) Functional sequelae were appreciated according to the RTOG/EORTC scale: 29 occurred in 21 pts.60% of them were depigmentation ((11(29))) and epilation ((6(29))). Among the 21 FSC of the eyelid, one lacrimal stenosis occurred (4,8%) Cosmetic results were judged 'good' or 'very good' for 83% of the pts (BONVALLOT criteria). Bad results occured more frequently for recurrent FSC According to the litterature, our study shows that interstitial BT is a good alternative to surgery for facial skin carcinoma for elderly patients

    Atrial dysfunction or "cardiopathy" has been recently proposed as a mechanism in cryptogenic stroke. A prolonged PR interval may reflect impaired atrial conduction and thus may be a biomarker of atrial cardiopathy. We aim to compare the prevalence of PR interval prolongation in patients with cryptogenic stroke (CS) when compared with known non-cryptogenic non-cardioembolic stroke (NCNCS) subtypes. We used prospective ischemic stroke databases of 3 comprehensive stroke centers to identify patients 18 years or older with a discharge diagnosis of ischemic non-cardioembolic stroke between December 1, 2013 and August 31, 2015. The main outcome was ischemic stroke subtype (CS versus NCNCS). We compared PR intervals as a continuous and categorical variable (PR interval prolongation and CS. We identified 644 patients with ischemic non-cardioembolic stroke (224 CS and 420 NCNCS). Patients with CS were more likely to have a PR of 200 milliseconds or greater when compared with those with NCNCS (23.2% versus 13.8%, P = .009). After adjusting for factors that were significant in univariate analyses, a PR of 200 milliseconds or greater was independently associated with CS (odds ratio [OR] 1.70, 95% CI 1.08-2.70). The association was more pronounced when excluding patients on atrioventricular nodal blocking agents (OR 2.64, 95% CI 1.44-4.83). A PR of 200 milliseconds or greater is associated with CS and may be a biomarker of atrial cardiopathy in the absence of atrial fibrillation. Prospective studies are needed to confirm this association. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    2011-01-01

    Background Montreal is Canada's second-largest city, where mean annual tuberculosis (TB) incidence from 1996 to 2007 was 8.9/100,000. The objectives of this study were to describe the epidemiology of TB among homeless persons in Montreal and assess patterns of transmission and sharing of key locations. Methods We reviewed demographic, clinical, and microbiologic data for all active TB cases reported in Montreal from 1996 to 2007 and identified persons who were homeless in the year prior to TB diagnosis. We genotyped all available Mycobacterium tuberculosis isolates by IS6110 restriction fragment length polymorphism (IS6110-RFLP) and spoligotyping, and used a geographic information system to identify potential locations for transmission between persons with matching isolates. Results There were 20 cases of TB in homeless persons, out of 1823 total reported from 1996-2007. 17/20 were Canadian-born, including 5 Aboriginals. Homeless persons were more likely than non-homeless persons to have pulmonary TB (20/20), smear-positive disease (17/20, odds ratio (OR) = 5.7, 95% confidence interval (CI): 1.7-20), HIV co-infection (12/20, OR = 14, 95%CI: 4.8-40), and a history of substance use. The median duration from symptom onset to diagnosis was 61 days for homeless persons vs. 28 days for non-homeless persons (P = 0.022). Eleven homeless persons with TB belonged to genotype-defined clusters (OR = 5.4, 95%CI: 2.2-13), and ten potential locations for transmission were identified, including health care facilities, homeless shelters/drop-in centres, and an Aboriginal community centre. Conclusions TB cases among homeless persons in Montreal raise concerns about delayed diagnosis and ongoing local transmission. PMID:22034944

    Full Text Available Background and Objective Sleep disturbances resulting from a mismatch between the sleep-wake schedule and an individual’s chronotype can influence work or school performance and numerous health outcomes. Individual chronotype can be determined by genetic factors, and is influenced by environmental factors which could change throughout life. We aimed to examine self-reported changes in chronotype during three different periods of life (childhood, teenage years, and adulthood. Methods Three hundred forty-three (age: 37.8 ± 11.6 years, range: 18–82; F: M = 214: 129 adult visitors to a National Museum in Korea were recruited for this study. The Korean version of the Horne-Östberg Morningness-Eveningness Questionnaire (MEQ-K was administered and standard MEQ-K scores were used to categorize subjects as morning type (MT, evening type (ET, or neither type (NT. Binary logistic regression analyses were applied to examine the relationships of gender, current age, and childhood/teenager ME type with change in chronotype between childhood, teenage years, and adulthood. Results The ages, gender distribution, and years of education were different between the chronotype groups (p < 0.01. Individuals who reported childhood MT or ET had a lower probability of changing their chronotype between childhood and their teenage years compared with individuals reporting childhood NT (p < 0.0001, whereas individuals reporting teenage MT or ET had a higher probability (p < 0.0001. Furthermore, older individuals had a lower probability of reporting a chronotype change between childhood or teenage years and adulthood (p < 0.01. Conclusions Most individuals reported the same chronotype from childhood to their teenage years but a different chronotype between the teenage years and adulthood. Older age was associated with a lower probability of reporting a different chronotype during childhood or teenage years.

    Full Text Available Introduction: Temporal bone fracture is usually associated with high energy head injury and can cause potentially severe complications. Immediate detection of temporal bone fracture and its complications helps in providing early and effective treatment, which if left untreated can have drastic consequences. Aim: The main objective of the study is to document the frequency and most prevalent type of temporal bone fracture, co-existing complications and to establish association between them. Materials and Methods: One year (2015-2016 retrospective study of head injured patients presented to the Emergency Department, Mysore Medical College And Research Institute was conducted. Age and gender distribution, cause of injury, radiological findings, otorhinolaryngological clinical presentations and treatment given were analyzed. The results were tabulated and were evaluated by Microsoft Excel 2013. Results: Out of 1450 patients evaluated for head injury 154 patients were positive for temporal bone fracture. Incidence of the study was 10.6%. Majority of the patients were male (66.2% and were between 30 to 40 years (50.1%. The major cause of injury was motor vehicle accidents (84.48%. Right side was involved (58.4% more than the left side (41.5%. Most common clinical presentation was otorrhea 68.8%, followed by otalgia (35.04% and otorhinorrhea (24.67%. Longitudinal type fracture was most frequent 56.25%. Otic capsule involvement was present in 35.93%. Most of the fractures were managed conservatively whereas surgery was required in 12 patients (7.7%. Conclusion: Temporal bone fractures were frequently associated with severe traumatic brain injury leading to serious long term morbidity and sequelae. CT-scan is of utmost importance in detection of fractures and its complications.

    To determine if preeclampsia is an independent predictor of diastolic dysfunction and what factors among patients with preeclampsia are associated with diastolic dysfunction. This is a retrospective cohort study of patients who delivered between 2008 and 2013 at a single institution who had a maternal echocardiogram during their pregnancy or within 5months of delivery. Patients with structural heart disease, ejection fraction less than 45%, pulmonary embolus, or age over 45years were excluded. Medical records were reviewed for medical and obstetric complications and echocardiogram findings. Demographic characteristics and rate of diastolic dysfunction were compared between patients with preeclampsia and without preeclampsia. Multivariate logistic regression was performed controlling for age, ethnicity, gestational age at delivery, diabetes, preeclampsia, intrauterine growth restriction (IUGR), antihypertensive use and magnesium sulfate administration. Sixty-six patients were identified, of which 39 (59%) had preeclampsia. Past history of preeclampsia, IUGR in the current pregnancy, antihypertensive use and magnesium sulfate use were higher in the preeclampsia group. Fifteen patients (39%) in the preeclampsia group were African-American compared to 2 (3%) in the control group (ppreeclampsia were found to have diastolic dysfunction compared to 3 (11%) controls (OR=6.18, 95% CI 1.59,24.02; p=0.006). Logistic regression analysis did not reveal other independent predictors of diastolic dysfunction. In the patients with preeclampsia, history of preeclampsia with severe features and IUGR were not associated with diastolic dysfunction. Our study supports previous findings that preeclampsia is associated with diastolic dysfunction. Copyright © 2015 International Society for the Study of Hypertension in Pregnancy.

    Yellow fever (YF) vaccine is considered safe; however, severe illness and death following vaccination have been reported. Vaccine Safety Datalink (VSD) and US Department of Defense (DoD) data were used to identify adverse reactions following YF vaccination. Within the VSD, YF-vaccine-exposed subjects were compared to age-, site-, and gender-matched unexposed subjects. YF-vaccine-exposed DoD subjects were studied using a risk-interval design. For both cohorts, ICD-9 codes were analyzed for allergic and local reactions, mild systemic reactions, and possible visceral and neurologic adverse events (AEs). The VSD cohort received 47,159 doses from 1991 through 2006. The DoD cohort received 1.12 million doses from 1999 through 2007. Most subjects received other vaccines simultaneously. In the VSD cohort, rates of allergic, local, and mild systemic reactions were not statistically different between YF-vaccine-exposed and -unexposed subjects. In the DoD, there was an increased risk for outpatient allergic events in the period following vaccination with YF and other vaccines rate ratios [RR 3.85, 95% confidence interval (CI) 3.35-4.41] but with no increased risk for inpatient allergic reactions. In both cohorts, inpatient ICD-9 codes for visceral events were significantly less common following vaccination; inpatient codes for neurologic events were less common in the VSD YF-vaccine-exposed adult cohort, but did not differ between exposed and unexposed periods in the DoD. In the DoD, one fatal case of YF-vaccine-associated viscerotropic disease (YF-vaccine-AVD) was detected. The estimated death rate was 0.89 for 1,000,000 YF vaccine doses (95% CI 0.12-6.31/1,000,000 doses). No YF vaccine-associated deaths occurred in the VSD. In these closed cohorts we did not detect increased risk for visceral or neurologic events following YF vaccination. The death rate following YF vaccine was consistent with previous reports. These data support current recommendations for use of YF

The median survival of patients of BCLC stages A, B, C and D was 33, 17.4, 6.9, and 1.8 mo, respectively (P < 0.05 for comparison between stages). The median survival of Child-Pugh A, B and C classes were 9.8 mo (range 6.4-13), 6.1 (range 4.9-7.3), and 3.7 (range 1.5-6), respectively (P < 0.05 for comparison between stages). By univariate analysis, the variables significantly associated to an increased liklihood of mortality were Eastern Cooperative Oncology Group performance status (PS), presence of ascites, low level of albumin, elevated level of bilirubin, international normalized ratio (INR) and Log-[(α fetoprotein (AFP)]. At multivariate analysis, mortality was independently predicted by bad PS (P < 0.0001), high INR values (P = 0.0001) and elevated Log-(AFP) levels (P = 0.009). This study confirms the heterogeneous behavior of untreated HCC. BCLC staging remains an important prognostic guide and may be important in decision-making for palliative treatment.

    In this paper we sought to reproduce, as a computational retrospective study in an EHR database (MIMIC-II), a recent large prospective clinical study: the 2013 publication, by the Japanese Association for Acute Medicine (JAAM), about disseminated intravascular coagulation, in the journal Critical Care (PMID: 23787004). We designed in SQL and Java a set of electronic phenotypes that reproduced the study's data sampling, and used R to perform the same statistical inference procedures. All produced source code is available online at https://github.com/fabkury/paamia2015. Our program identified 2,257 eligible patients in MIMIC-II, and the results remarkably agreed with the prospective study. A minority of the needed data elements was not found in MIMIC-II, and statistically significant inferences were possible in the majority of the cases.

    Methadone administration has increased in pediatric clinical settings. This review is an attempt to ascertain an equianalgesic dose ratio for methadone in the pediatric population using standard adult dose conversion guidelines. US tertiary children's hospital. Hospitalized pediatric patients, 0-18 years of age. A retrospective chart review was conducted for patients who were converted from their initial opioid therapy regimen (morphine, hydromorphone, and/or fentanyl) to methadone. The primary endpoint was whether or not a dose correction was needed for methadone in the 6 days following conversion using standard dose conversion charts for adults. Documented clinical signs of withdrawal, unrelieved pain, or oversedation were examined. The majority (53.7 percent) of the 199 children were converted to methadone on intensive care units prior extubation or postextubation. The mean conversion ratio was 23.7 mg of oral morphine to 1 mg of oral methadone (median, 18.8 mg:1 mg, SD=25.7). Most patients experienced an adequate conversion (n=115, 57.8 percent), while 83 (41.7 percent) appeared undermedicated, and one child was oversedated. There were no associations found with conversion ratios for initial morphine dose, days to conversion, or effect of withdrawal of concomitant agents with potential for withdrawal. Opioid conversion to methadone is commonly practiced at our institution; however, dosing was significantly lower compared to adult conversion ratios, and more than 40 percent of children were undermedicated. The majority of children in this study received opioids for sedation while intubated and ventilated; therefore, safe and efficacious pediatric methadone conversion rates remain unclear. Prospective studies are needed.

  9. Achieving and sustaining profound institutional change in healthcare: case study using neo-institutional theory.

    Change efforts in healthcare sometimes have an ambitious, whole-system remit and seek to achieve fundamental changes in norms and organisational culture rather than (or as well as) restructuring the service. Long-term evaluation of such initiatives is rarely undertaken. We report a secondary analysis of data from an evaluation of a profound institutional change effort in London, England, using a mixed-method longitudinal case study design. The service had received £15 million modernisation funding in 2004, covering multiple organisations and sectors and overseen by a bespoke management and governance infrastructure that was dismantled in 2008. In 2010-11, we gathered data (activity statistics, documents, interviews, questionnaires, site visits) and compared these with data from 2003 to 2008. Data analysis was informed by neo-institutional theory, which considers organisational change as resulting from the material-resource environment and three 'institutional pillars' (regulative, normative and cultural-cognitive), enacted and reproduced via the identities, values and activities of human actors. Explaining the long-term fortunes of the different components of the original programme and their continuing adaptation to a changing context required attention to all three of Scott's pillars and to the interplay between macro institutional structures and embedded human agency. The paper illustrates how neo-institutional theory (which is typically used by academics to theorise macro-level changes in institutional structures over time) can also be applied at a more meso level to inform an empirical analysis of how healthcare organisations achieve change and what helps or hinders efforts to sustain those changes.

    This study was driven forward centering around physical techniques in retrospective dosimetry system for encountering nuclear radiation accident. The results obtained through this study are summarized as follow : the minimal facilities based on physical techniques should be assured at KINS for appropriate operation and establishment of retrospective accident dosimetry system, the necessary apparatus and man power for retrospective dose assessment by physical techniques might be operated flexibly, however, CL and TL/OSL readers should be equipped with the highest priority, a series of comparative examination of several physical techniques for retrospective dose assessment revealed that most of the irradiated materials around accident sites are usable for the dose assessment, if a priori study on the dosimetrical characteristics of those materials is preceded in accordance with the species of the collectable samples, the results of the study on the CL-dose response and radiation energy dependence of sugar and sorbitol, showed the nonlinearity in CL-dose relationship at the range of low dose(less than 5 Gy), and it led us to perform a study on the correction of the nonlinearity, and in the later study, CL output showed heavy dependence on radiation energy in the energy below around 100 keV and accordingly, a study on the correction for the energy dependence was also carried out, ve were able to obtain good results as a first attempt to carry out such corrections.

    To retrospectively analyze treatment outcomes after particle therapy using protons or carbon ions for mucosal melanoma of the head and neck (HNMM) at the Hyogo Ion Beam Medical Center, as well as to compare proton therapy (PT) and carbon ion therapy (CIT). Data from 62 HNMM patients without metastasis, treated with PT or CIT between October 2003 and April 2011 were analyzed. Median patient age was 70.5 years (range 33-89 years). Of the total patients, 33 (53 %) had received PT and 29 (47 %) had undergone CIT. Protocols for 65 or 70.2 GyE in 26 fractions were used for both ion types. Median follow-up was 18.0 months (range 5.2-82.7 months). The 1-/2-year overall survival (OS) and local control (LC) rates were 93 %/61 % and 93 %/78 % for all patients, 91 %/44 % and 92 %/71 % for the PT patients and 96 %/62 % and 95 %/59 % for the CIT patients, respectively. No significant differences were observed between PT and CIT. Local recurrence was observed in 8 patients (PT: 5, CIT: 3) and 29 (PT: 18, CIT: 11) experienced distant metastases. Acute reactions were acceptable and all patients completed the planned radiotherapy. Regarding late toxicity, grade 3 or greater events were observed in 5 patients (PT: 3, CIT: 2), but no significant difference was observed between PT and CIT. Our single-institution retrospective analysis demonstrated that particle therapy for HNMM achieved good LC, but OS was unsatisfactory. There were no significant differences between PT and CIT in terms of either efficacy or toxicity. (orig.)

    Smoking is a well-known risk factor for esophageal cancer. However, there are few reports that directly evaluate smoking as a prognostic factor for esophageal cancer. Moreover, scarce evidence is available on whether smoking interacts with major treatment modalities of esophageal cancer. In this study we retrospectively analyzed 364 patients with esophageal squamous cell cancer who were treated between 2001 and 2005 at our institution. Background characteristics, including smoking history, were analyzed as potential prognostic factors. Of the 363 patients, 76 patients (20.9%) were non-smokers or light smokers (non-heavy), whereas 287 patients (79.1%) were heavy smokers. The 5-year survival rate for non-heavy smokers and heavy smokers was 61.8% (95% confidence interval [CI]: 49.1-72.2) vs 44.6% (95% CI: 38.2-50.9), respectively. In a multivariate Cox model (adjusted for age, gender, performance status, alcohol consumption, histology, tumor length, International Union Against Cancer [UICC] stage, and treatment), the hazard ratio for heavy smokers in comparison with non-heavy smokers was 1.73 (95% CI: 1.12-2.68; P=0.013). When we stratified by treatment method, heavy smoking was significantly associated with poor survival only in patients treated by chemoradiotherapy (hazard ratio, 2.43; 95% CI: 1.38-4.27; P=0.002). More importantly, a statistically significant interaction between heavy smoking history and treatment modality was observed (P=0.041). Our results indicated that smoking history is strongly associated with poor prognosis in patients with esophageal cancer, especially those treated by chemoradiotherapy. Further investigation is warranted to explain this different prognosis. (author)

    Social media have strongly influenced awareness and perceptions of public health emergencies, but a considerable amount of social media content is now carried through images, rather than just text. This study's objective is to explore how image-sharing platforms are used for information dissemination in public health emergencies. Retrospective review of images posted on two popular image-sharing platforms to characterize public discourse about Ebola. Using the keyword '#ebola' we identified a 1% sample of images posted on Instagram and Flickr across two sequential weeks in November 2014. Images from both platforms were independently coded by two reviewers and characterized by themes. We reviewed 1217 images posted on Instagram and Flickr and identified themes. Nine distinct themes were identified. These included: images of health care workers and professionals [308 (25%)], West Africa [75 (6%)], the Ebola virus [59 (5%)], and artistic renderings of Ebola [64 (5%)]. Also identified were images with accompanying embedded text related to Ebola and associated: facts [68 (6%)], fears [40 (3%)], politics [46 (4%)], and jokes [284 (23%)]. Several [273 (22%)] images were unrelated to Ebola or its sequelae. Instagram images were primarily coded as jokes [255 (42%)] or unrelated [219 (36%)], while Flickr images primarily depicted health care workers and other professionals [281 (46%)] providing care or other services for prevention or treatment. Image sharing platforms are being used for information exchange about public health crises, like Ebola. Use differs by platform and discerning these differences can help inform future uses for health care professionals and researchers seeking to assess public fears and misinformation or provide targeted education/awareness interventions.

    Full Text Available Changes in population birth outcomes, including increases in low birthweight or preterm births, have been documented after natural and manmade disasters. However, information is limited following the 2011 Fukushima Daiichi Nuclear Power Plant Disaster. In this study, we assessed whether there were long-term changes in birth outcomes post-disaster, compared to pre-disaster data, and whether residential area and food purchasing patterns, as proxy measurements of evacuation and radiation-related anxiety, were associated with post-disaster birth outcomes. Maternal and perinatal data were retrospectively collected for all live singleton births at a public hospital, located 23 km from the power plant, from 2008 to 2015. Proportions of low birthweight (<2500 g at birth and preterm births (<37 weeks gestation at birth were compared pre- and post-disaster, and regression models were conducted to assess for associations between these outcomes and evacuation and food avoidance. A total of 1101 live singleton births were included. There were no increased proportions of low birthweight or preterm births in any year after the disaster (merged post-disaster risk ratio of low birthweight birth: 0.98, 95% confidence interval (CI: 0.64–1.51; and preterm birth: 0.68, 95% CI: 0.38–1.21. No significant associations between birth outcomes and residential area or food purchasing patterns were identified, after adjustment for covariates. In conclusion, no changes in birth outcomes were found in this institution-based investigation after the Fukushima disaster. Further research is needed on the pathways that may exacerbate or reduce disaster effects on maternal and perinatal health.

    2017-01-01

    The objective of this study is to provide demographical and clinical descriptions of patients age 65 years old and older who were treated with peripheral nerve blocks (PNBs) at our institution and evaluate the safety and efficacy of this treatment. Headache disorders are common, disabling chronic neurological diseases that often persist with advancing age. Geriatric headache management poses unique therapeutic challenges because of considerations of comorbidity, drug interactions, and adverse effects. Peripheral nerve blocks are commonly used for acute and short-term prophylactic treatment for headache disorders and may be a safer alternative to standard pharmacotherapy in this demographic. We performed a single center, retrospective chart review of patients at least 65 years of age who received peripheral nerve blocks for headache management over a 6 year period. Sixty-four patients were mostly female (78%) with an average age of 71 years (range 65-94). Representative headache diagnoses were chronic migraine 50%, episodic migraine 12.5%, trigeminal autonomic cephalalgia 9.4%, and occipital neuralgia 7.8%. Average number of headache days/month was 23. Common comorbidities were hypertension 48%, hyperlipidemia 42%, arthritis 27%, depression 47%, and anxiety 33%. Eighty-nine percent were prescribed at least 1 medication fulfilling the Beers criteria. The average number of peripheral nerve blocks per patient was 4. Peripheral nerve blocks were felt to be effective in 73% for all headaches, 81% for chronic migraine, 75% for episodic migraine, 67% for chronic tension type headache, 67% for new daily persistent headache, and 60% for occipital neuralgia. There were no adverse events related to PNBs reported. PNBs might be a safe and effective alternative headache management strategy for older adults. Medical and psychiatric comorbidities, medication overuse, and Beers list medication rates were extraordinarily high, giving credence to the use of peripherally administered

    We report a multicentre retrospective study that analysed clinical characteristics and outcomes in 117 patients with primary plasma cell leukaemia (pPCL) treated at the participating institutions between January 2006 and December 2016. The median age at the time of pPCL diagnosis was 61 years. Ninety-eight patients were treated with novel agents, with an overall response rate of 78%. Fifty-five patients (64%) patients underwent upfront autologous stem cell transplantation (ASCT). The median follow-up time was 50 months (95% confidence interval [CI] 33; 76), with a median overall survival (OS) for the entire group of 23 months (95% CI 15; 34). The median OS time in patients who underwent upfront ASCT was 35 months (95% CI 24·3; 46) as compared to 13 months (95% CI 6·3; 35·8) in patients who did not receive ASCT (P = 0·001). Multivariate analyses identified age ≥60 years, platelet count ≤100 × 10 9 /l and peripheral blood plasma cell count ≥20 × 10 9 /l as independent predictors of worse survival. The median OS in patients with 0, 1 or 2-3 of these risk factors was 46, 27 and 12 months, respectively (P < 0·001). Our findings support the use of novel agents and ASCT as frontline treatment in patients with pPCL. The constructed prognostic score should be independently validated. © 2018 John Wiley & Sons Ltd.

This study is a retrospective review of 49 limbs in 38 patients with PAES treated surgically over an 8-year period.Patients and methods: From 1995 to 2002, 38 patients with a mean age of 21 years (range, 18–29 years underwent surgery for PAES at a single institution. The patients’ demographic data and clinical features are recorded. The preoperative diagnosis of PAES was made based on various combinations of investigations including positional stress test, duplex ultrasonography, computed tomography, computed tomographic angiography, and angiography. Results: Nine, 33, and 7 patients had Delaney’s type I, II, and III PAES respectively. The surgical procedures consisted of simple release of the popliteal artery in 33 limbs (67.3%, autogenous saphenous vein (ASV patch angioplasty with or without thromboendarterectomy (TEA in 5 limbs (10.2% and ASV graft interposition or bypass in 11 limbs (22.5%. At a median follow up of 34 months (range, 8–42 months, there were no postoperative complications and all the patients were cured of their symptoms.Conclusions: PAES is an unusual but important cause of peripheral vascular insufficiency especially in young patients. Early diagnosis through a combined approach is necessary for exact diagnosis. Popliteal artery release alone or with vein bypass is the treatment of choice when intervention is indicated for good operative outcome and to prevent limb loss.Keywords: popliteal artery, entrapment syndrome, diagnosis, surgery, treatment

  2. Reticulocyte Hemoglobin Content Helps Avoid Iron Overload in Hemodialysis Patients: A Retrospective Observational Study.

    Anemia in patients suffering from end-stage renal failure is currently treated with Erythropoiesis-Stimulating Agents (ESA). This treatment needs sufficient iron supplementation to avoid an inadequate dosage of ESA. Nowadays modern analytical instruments allow to accurately calculate the content of Hemoglobin (Hb) in reticulocytes (CHr), that can be used as a guide for prescribing patients with the appropriate amount of iron. Patients, undergoing hemodialysis, were retrospectively selected from the database and were divided in two groups: group A received intravenous (IV) iron and subcutaneously ESA, and their dosages were adjusted on the basis of the following parameters: Hb, Mean corpuscular haemoglobin (MCH), CHr with consequent MCH/CHr ratio and reticulocyte count determined by the ADVIA 120 Hematology System of Siemens; group B patients were administered IV iron and ESA monitoring iron storage, Hb and ferritin. The aforementioned parameters and the administered amount of iron and ESA were monitored at baseline, four and eight months from the begining of the study. For ESA supplementation, no difference was observed between the groups at the various observed times. Despite similar Hb levels, the patients of group A needed significant lower doses of IV iron (-57.8%) avoiding risks of organ toxicity and obtaining consequent cost saving of nearly 1 €/patient/month. The use of CHr and its related parameters allows the avoidance of overdosage of IV iron, which can potentially damage organs, and the reduction of health care direct and indirect costs.

    Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

  19. An ecological approach to prospective and retrospective timing of long durations: a study involving gamers.

    Simon Tobin

    Full Text Available To date, most studies comparing prospective and retrospective timing have failed to use long durations and tasks with a certain degree of ecological validity. The present study assessed the effect of the timing paradigm on playing video games in a "naturalistic environment" (gaming centers. In addition, as it involved gamers, it provided an opportunity to examine the effect of gaming profile on time estimation. A total of 116 participants were asked to estimate prospectively or retrospectively a video game session lasting 12, 35 or 58 minutes. The results indicate that time is perceived as longer in the prospective paradigm than in the retrospective one, although the variability of estimates is the same. Moreover, the 12-minute session was perceived as longer, proportionally, than the 35- and 58-minute sessions. The study also revealed that the number of hours participants spent playing video games per week was a significant predictor of time estimates. To account for the main findings, the differences between prospective and retrospective timing are discussed in quantitative terms using a proposed theoretical framework, which states that both paradigms use the same cognitive processes, but in different proportions. Finally, the hypothesis that gamers play more because they underestimate time is also discussed.

    This study is the result of two Portuguese case-control studies that examined the replication of retrospective correlates and preceding life events in anorexia nervosa (AN) and bulimia nervosa (BN) development. This study aims to identify retrospective correlates that distinguish AN and BN METHOD: A case-control design was used to compare a group of women who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for AN (N = 98) and BN (N = 79) with healthy controls (N = 86) and with other psychiatric disorders (N = 68). Each control group was matched with AN patients regarding age and parental social categories. Risk factors were assessed by interviewing each person with the Oxford Risk Factor Interview. Compared to AN, women with BN reported significantly higher rates of paternal high expectations, excessive family importance placed on fitness/keeping in shape, and negative consequences due to adolescent overweight and adolescent objective overweight. Overweight during adolescence emerged as the most relevant retrospective correlate in the distinction between BN and AN participants. Family expectations and the importance placed on keeping in shape were also significant retrospective correlates in the BN group.

    Full Text Available Objective: To determine the prevalence of resistant strains of Staphylococcus aureus (S. aureus isolated from Skin and soft tissue infections (SSTI to various antibiotics. Material and Methods: All culture-positive results for S. aureus from swabs taken from patients presenting at one Greek hospital with a skin infection between the years 2010–2015 were examined retrospectively. Bacterial cultures, identification of S. aureus and antimicrobial susceptibility testing were performed using the disk diffusion method according to Clinical and Laboratory Standards Institute (CLSI guidelines and European Committee on Antimicrobial testing (EUCAST breakpoints. EUCAST breakpoints were applied if no CLSI were available. Results: Of 2069 S. aureus isolates identified, 1845 (88% were resistant to one or more antibiotics. The highest resistance was observed for benzylpenicillin (71.9%, followed by erythromycin (34.3%. Resistant strains to cefoxitin defined as MRSA (methicillin-resistant S. aureus represented 21% of total isolates. Interestingly, resistance to fusidic acid was 22.9% and to mupirocin as high as 12.7%. Low rates were observed for minocycline, rifampicin and trimethoprim/sulfamethoxazole (SXT. Resistance to antibiotics remained relatively stable throughout the six-year period, with the exception of cefoxitin, fusidic acid and SXT. A high percentage of MRSA strains were resistant to erythromycin (60%, fusidic acid (46%, clindamycin (38% and tetracycline (35.5%. Conclusions: Special attention is required in prescribing appropriate antibiotic therapeutic regimens, particularly for MRSA. These data on the susceptibility of S. aureus may be useful for guiding antibiotic treatment.

    Although sexual activity can cause moderate stress, it can cause natural death in individuals with pre-existing illness. The aim of this study was to identify additional pre-existing health problems, sexual practices, and potential circumstances that may trigger fatal events. This medicolegal postmortem, retrospective, and prospective study is based on data of autopsies performed at the Institute of Legal Medicine of the University hospital, Goethe-University, Frankfurt/Main, Germany. Identification of pre-existing health problems, sexual practices, and potential circumstances than could trigger fatal events. From 1972 to 2016 (45 years) approximately 38,000 medicolegal autopsies were performed, of which 99 cases of natural death were connected to sexual activities (0.26%). Except for eight women, men represented most cases. The women's mean age was 45 years (median = 45) and the men's mean age was 57.2 years (median = 57). Causes of death were coronary heart disease (n = 28), myocardial infarction (n = 21) and reinfarction (n = 17), cerebral hemorrhage (n = 12), rupture of aortic aneurysms (n = 8), cardiomyopathy (n = 8), acute heart failure (n = 2), sudden cardiac arrest (n = 1), myocarditis (n = 1), and a combination of post myocardial infarction and cocaine intoxication (n = 1). Most cases showed increased heart weights and body mass indices. Death occurred mainly during the summer and spring and in the home of the deceased. If sexual partners were identified, 34 men died during or after sexual contact with a female prostitute, two cases at least two female prostitutes. Nine men died during or after sexual intercourse with their wife, in seven cases the sexual partner was a mistress, and in four cases the life partner. Five men died during homosexual contacts. Based on the situation 30 men were found in, death occurred during masturbation. Of the women, five died during intercourse with the life partner, two died during intercourse with a lover or

    WHAT IS KNOWN ON THE SUBJECT?: Various expert opinions reported relational benefits and tranquilizing effects of therapeutic body wraps (TBW) in adults experiencing high anxiety in the context of psychosis. Yet, this tranquilizing effect was never investigated in larger samples and in the context of modern psychopharmacology. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This is the first study to establish descriptive statistics of this mind-body therapy in French-speaking Switzerland where TBWs are routinely used in two public psychiatric hospitals. It brings knowledge on patients nowadays treated with TBW. Moreover, it opens a new area of investigation on the potential of this nursing technique, which may contribute to reduce anxiolytic medication in severely ill patients. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: This study sheds light on a clinical practice in mental health nursing and upon nurses' specific contribution to psychiatric clinic. It investigates a potential for TBWs to reduce the use of anxiolytic medications by patients who agreed to have TBW as part of their treatment. It may help to inform the mental health nursing practice. Introduction Many patients suffering from serious mental illness experience severe anxiety and those with psychosis often report the feeling of their bodies falling apart. While it is believed that these patients benefit from therapeutic body wraps (TBWs), the use of this adjunct therapy has rarely been studied in adult patients. Aims The aim of this study was to obtain descriptive statistics on the clinical, social-demographic and institutional reality of TBW therapy in Swiss public adult inpatient wards. Methods Retrospective data related to a cohort of 172 adult inpatients were retrieved from records of two public hospitals. Correlations between TBW and the prescriptions of lorazepam were explored. Results TBWs were primarily used for patients diagnosed with either schizophrenia, schizotypal, delusional and other non

    Complex ventral hernia is a challenging surgical entity, commonly attended with huge defect, loss of domain and possible soft tissue infection. It is difficult to repair, especially with multiple recurrences. Numerous methods of repair have been described with no evidence-based data available to prefer one method over the other. The purpose of this study is to determine the long-term outcome of the proposed new modification of intraperitoneal mesh repair procedure in complex ventral hernia. This is a single-center retrospective analysis utilizing the prospectively-maintained dataset in our institution during the study period between January 2003 and June 2017. Patients who fit the inclusion criteria of having a complex ventral hernia, whether de-novo or recurrent and were subjected to A. Double Mesh Intraperitoneal Repair (ADMIR) procedure were included in the study. Patients were followed up till recurrence or lost to follow through a period ranging from 6 to 174 months (mean: 142.96 ± SE: 11.91). Forty-nine cases were included in this study (38 females and 11 males) with a female to male ratio of 3.5:1. The age range was from 28 to 81 years (mean 49 ± 12.4). BMI range from 25 to 42 (mean 33.6 ± 5.42). The ratio between the hernia sac volume and abdominal cavity volume was more than 20% in 12 patients (24.5%), who were subjected to preoperative progressive pneumoperitoneum (PPP) for an average period of two weeks. Hernias were recurrent in 28 cases (57%) and associated comorbidities were observed in 29 patients (63%). Postoperative complications occurred in 19 patients (38.7%), among them only 2 patients developed recurrence (4%) after a mean follow up period of 142 months. Five patients were lost to follow and were included in the Kaplan and Meier survival analysis. ADMIR procedure is successful for the repair of complex ventral hernias as it is applicable to all sites of ventral hernias. The mesh is tension free hidden within the abdomen allowing

    Full Text Available Background Our study aimed to compare the outcomes of surgical treatment of tongue cancer patients in three different age groups. Methods From 2004 to 2013, we retrospectively analyzed the clinical data of 1,712 patients who were treated in the four institutions constituting the Chang Gung Memorial Hospitals (CGMH. We divided and studied the patients in three age groups: Group 1, younger (<65 years; Group 2, young old (65 to <75; and Group 3, older old patients (≥75 years. Results Multivariate analyses determined the unfavorable, independent prognostic factors of overall survival to be male sex, older age, advanced stage, advanced T, N classifications, and surgery plus chemotherapy. No significant differences were found in adjusted hazard ratios (HR of death in early-stage disease (stage I–II among Group 1 (HR 1.0, Group 2 (HR 1.43, 95% confidence interval (CI [0.87–2.34], p = 0.158, and Group 3 (HR 1.22, 95% CI [0.49–3.03], p = 0.664 patients. However, amongst advanced-stage patients (stage (III–IV, Group 3 (HR 2.53, 95% CI [1.46–4.38], p  = 0.001 showed significantly worse survival than the other two groups after other variables were adjusted for. Fourteen out of 21 older old, advanced-staged patients finally died, and most of the mortalities were non-cancerogenic (9/14, 64.3%, and mostly occurred within one year (12/14, 85% after cancer diagnosis. These non-cancer cause of death included underlying diseases in combination with infection, pneumonia, poor nutrition status, and trauma. Conclusions Our study showed that advanced T classification (T3–4, positive nodal metastasis (N1–3 and poorly differentiated tumor predicted poor survival for all patients. Outcome of early-stage patients (stage I–II among three age groups were not significantly different. However, for advanced-stage patients (stage III–IV, the older old patients (≥75 had significantly worse survival than the other two patient groups. Therefore, for early

Purpose: The purpose of our study was to compare patients’ bodily pain and quality of life (QOL, in addition to the procedural benefit and patient satisfaction, before and after musculoskeletal injections in the office setting. Patients and methods: Patients were eligible for recruitment if they were over age 18 and had an injection for musculoskeletal pain from a primary care provider in an office procedural practice. Included in our analysis were knee joint/bursa, trochanteric bursa, and shoulder joint/bursa injection sites. The variables measured were pain, benefit from the injection, QOL physical and mental components, and patient satisfaction. This was a retrospective cohort study approved by the institutional review board. Results: Patients’ pain was assessed by the patients using a six-point Likert scale (none, very mild, mild, moderate, severe, and very severe. We noted that self-perception of pain decreased from 3.10 (± standard deviation at baseline 0.96 before to 2.36 (± standard deviation after the infection 1.21 (P = 0.0001 after the injection. In terms of the impact on QOL, our patients had a pre-injection physical score of 37.25 ± 8.39 and a mental score at 52.81 ± 8.98. After the injections, the physical score improved to 42.35 ± 9.07 (P = 0.0001 and the mental to 53.54 ± 8.20 (P = 0.0001 for the overall group. Ninety-six percent of the patients reported they were satisfied or extremely satisfied in the procedure clinic.

    Objectives To determine whether high performing hospitals with low 30 day risk standardized readmission rates have a lower proportion of readmissions from specific diagnoses and time periods after admission or instead have a similar distribution of readmission diagnoses and timing to lower performing institutions. Design Retrospective cohort study. Setting Medicare beneficiaries in the United States. Participants Patients aged 65 and older who were readmitted within 30 days after hospital admission for heart failure, acute myocardial infarction, or pneumonia in 2007-09. Main outcome measures Readmission diagnoses were classified with a modified version of the Centers for Medicare and Medicaid Services’ condition categories, and readmission timing was classified by day (0-30) after hospital discharge. Hospital 30 day risk standardized readmission rates over the three years of study were calculated with public reporting methods of the US federal government, and hospitals were categorized with bootstrap analysis as having high, average, or low readmission performance for each index condition. High and low performing hospitals had ≥95% probability of having an interval estimate respectively less than or greater than the national 30 day readmission rate over the three year period of study. All remaining hospitals were considered average performers. Results For readmissions in the 30 days after the index admission, there were 320 003 after 1 291 211 admissions for heart failure (4041 hospitals), 102 536 after 517 827 admissions for acute myocardial infarction (2378 hospitals), and 208 438 after 1 135 932 admissions for pneumonia (4283 hospitals). The distribution of readmissions by diagnosis was similar across categories of hospital performance for all three conditions. High performing hospitals had fewer readmissions for all common diagnoses. Median time to readmission was similar by hospital performance for heart failure and acute myocardial

    The purpose of this study was to compare the predictive validity, economic efficiency, and faculty staff satisfaction of a computerized test versus a personal interview as admission methods for graduate nursing studies. A mixed method study was designed, including cross-sectional and retrospective cohorts, interviews, and cost analysis. One hundred and thirty-four students in the Master of Nursing program participated. The success of students in required core courses was similar in both admission method groups. The personal interview method was found to be a significant predictor of success, with cognitive variables the only significant contributors to the model. Higher satisfaction levels were reported with the computerized test compared with the personal interview method. The cost of the personal interview method, in annual hourly work, was 2.28 times higher than the computerized test. These findings may promote discussion regarding the cost benefit of the personal interview as an admission method for advanced academic studies in healthcare professions. © 2016 John Wiley & Sons Australia, Ltd.

    Community district heating, utilizing hot water produced through electrical/thermal cogeneration, is seen as an integral part of Minnesota's Energy Policy and Conservation Plan. Several studies have been conducted which consider the technical and institutional issues affecting implementation of cogenerated district heating in the Minneapolis and St. Paul Metropolitan Area. The state of the technical art of cogenerated hot water district heating is assumed to be transferable from European experience. Institutional questions relating to such factors as the form of ownership, financing, operation, regulation, and product marketability cannot be transferred from the European experience, and have been the subject of an extensive investigation. The form and function of the Institutional Issues Study, and some of the preliminary conclusions and recommendations resulting from the study are discussed.

    To determine whether the quality of press releases issued by medical journals can influence the quality of associated newspaper stories. Retrospective cohort study of medical journal press releases and associated news stories. We reviewed consecutive issues (going backwards from January 2009) of five major medical journals (Annals of Internal Medicine, BMJ, Journal of the National Cancer Institute, JAMA, and New England Journal of Medicine) to identify the first 100 original research articles with quantifiable outcomes and that had generated any newspaper coverage (unique stories ≥100 words long). We identified 759 associated newspaper stories using Lexis Nexis and Factiva searches, and 68 journal press releases using Eurekalert and journal website searches. Two independent research assistants assessed the quality of journal articles, press releases, and a stratified random sample of associated newspaper stories (n=343) by using a structured coding scheme for the presence of specific quality measures: basic study facts, quantification of the main result, harms, and limitations. Proportion of newspaper stories with specific quality measures (adjusted for whether the quality measure was present in the journal article's abstract or editor note). We recorded a median of three newspaper stories per journal article (range 1-72). Of 343 stories analysed, 71% reported on articles for which medical journals had issued press releases. 9% of stories quantified the main result with absolute risks when this information was not in the press release, 53% did so when it was in the press release (relative risk 6.0, 95% confidence interval 2.3 to 15.4), and 20% when no press release was issued (2.2, 0.83 to 6.1). 133 (39%) stories reported on research describing beneficial interventions. 24% mentioned harms (or specifically declared no harms) when harms were not mentioned in the press release, 68% when mentioned in the press release (2.8, 1.1 to 7.4), and 36% when no press release

    Background Geriatric falls are leading causes of hospital trauma admissions and injury-related deaths. Medication use is a crucial element among extrinsic risk factors for falls. To reduce fall risk and the prevalence of adverse drug reactions, potentially inappropriate medication (PIM) lists are widely used. Objective Our aim was to investigate the possible predictors of geriatric falls annualized over a 5-year-long period, as well as to evaluate the medication use of nursing home residents. Setting Nursing home residents were recruited from the same institution between 2010 and 2015 in Szeged, Hungary. Method A retrospective epidemiological study was performed. Patient data were analysed for the first 12 months of residency. Chi-squared test and Fisher's-test were applied to compare the categorical variables, Student's t test to compare the continuous variables between groups. Binary logistic regression analysis was carried out to determine the association of falls with other variables found significant in univariate analysis. Microsoft Excel, IBM SPSS Statistics (version 23) and R (3.2.2) programs were used for data analysis. Main outcome measure Falls affected by age, gender, number of chronic medications, polypharmacy, PIM meds. Results A total of 197 nursing home residents were included, 150 (76.2%) women and 47 (23.8%) men, 55 fallers (annual fall prevalence rate was 27.9%) and 142 non-fallers. Gender was not a predisposing factor for falls (prevalence in males: 23.4 vs 29.3% in females, p > 0.05). Fallers were older (mean years ± SD; 84.0 ± 7.0) than non-fallers (80.1 ± 9.3, p factor for falls (p factor of falls (p fall risk were taken by 70.9% of fallers and 75.3% of non-fallers (p > 0.05). Taking pantoprazole, vinpocetine or trimetazidine was a significant risk factor for falls. Conclusion Older age, polypharmacy and the independent use of pantoprazole, vinpocetine, and trimetazidine were found to be major risk factors for falls. Further

    Weight gain during pregnancy has an important impact on maternal and neonatal health. Unlike the Institute of Medicine (IOM) recommendations for weight gain in singleton pregnancies, those for twin gestations are termed "provisional", as they are based on limited data. The objectives of this study were to determine the neonatal and maternal outcomes associated with gaining weight below, within and above the IOM provisional guidelines on gestational weight gain in twin pregnancies, and additionally, to explore ranges of gestational weight gain among women who delivered twins at the recommended gestational age and birth weight, and those who did not. A retrospective cohort study of women who gave birth to twins at ≥20 weeks gestation, with a birth weight ≥ 500 g was conducted in Nova Scotia, Canada (2003-2014). Our primary outcome of interest was small for gestational age (gain were used to categorize women as gaining below, within, or above guidelines. We performed traditional regression analyses for maternal outcomes, and to account for the correlated nature of the neonatal outcomes in twins, we used generalized estimating equations (GEE). A total of 1482 twins and 741 mothers were included, of whom 27%, 43%, and 30% gained below, within, and above guidelines, respectively. The incidence of small for gestational age in these three groups was 30%, 21%, and 20%, respectively, and relative to gaining within guidelines, the adjusted odds ratios were 1.44 (95% CI 1.01-2.06) for gaining below and 0.92 (95% CI 0.62-1.36) for gaining above. The gestational weight gain in women who delivered twins at 37-42 weeks with average birth weight ≥ 2500 g and those who delivered twins outside of the recommend ranges were comparable to each other and the IOM recommendations. While gestational weight gain below guidelines for twins was associated with some adverse neonatal outcomes, additional research exploring alternate ranges of gestational weight gain in twin

    This paper reports on institutional solid waste management in three Tanzanian institutions. It is noted that there are indeed advantages in managing solid waste at institutional level because of the institutions' unique characteristics that also influence their waste management needs. The paper outlines findings from a yearlong study on institutional solid waste management at three institutions: University of Dar es Salaam (UDSM), University College of Lands and Architectural Studies (UCLAS) and Water Resources Institute (WRI). Surveys and field investigations, including on-site waste measurements and questionnaire surveys were done at UDSM, UCLAS and WRI. The study has revealed, among other things, that per capita waste generation rates, W{sub G} vary between staff and students within each institution as well as among the three institutions. The composition of the waste was found to be predominantly organic in nature, suggesting a strong resource recovery potential in terms of animal feed or production of biogas through anaerobic digestion. Additionally, the W{sub G} was found to vary in line with changes in institutional activities like normal studies, examinations and holidays. The study has shown that resource recovery could greatly enhance solid waste management at the case study institutions.

    Research purpose: The objectives of this study were to establish an understanding of ‘transformational leadership’ and to determine the extent to which it was employed by leaders in an institution of higher education which had incorporated another institution. Motivations for the study: The study provides a starting point, not only for the successful implementation of higher education changes in the future but also the building of leadership commitment and alignment to the proposed changes in the sector as well as the development of institutional leadership teams to take responsibility for any other transformation processes. Research design, approach and method: The population of the study consisted of 350 full-time employees of the institution who had experienced the incorporation process. Two samples – one consisting of six executive management leaders and the other consisting of 153 employees – were used. Both qualitative and quantitative research approaches were employed using the case study method. Main findings: Results showed that transformational principles of idealised influence, intellectual stimulation, and inspirational motivation principles were used more than others and that employees were generally not satisfied with how the incorporation process had taken place. Practical/managerial implications: The results of the study affected the attitude and satisfaction of the employees in this study. Contribution/value-add: The study reveals that leaders in the institution played key roles such as shared vision, team work and the creation of an enabling environment. An important point that has emanated from this study is the evidence that during transformation, a lack of strategic direction and empowering of followers and capacitating them leads to dissatisfaction with the whole process, despite the transformation process being declared a success.

    Purpose: To evaluate clinical and lung dose-volume histogram based factors as predictors of radiation pneumonitis (RP) in lung cancer patients (PTs) treated with thoracic irradiation. Methods and materials: Records of all lung cancer PTs irradiated at our Institution between 1994 and 2000 were retrospectively reviewed. Eighty-four PTs with small or non-small-cell lung cancer, irradiated at >40 Gy, with full 3D dosimetry data and a follow-up time of >6 months from start of treatment, were analysed for RP. Pneumonitis was scored on the basis of SWOG toxicity criteria and was considered a complication when grade≥II. The following clinical parameters were considered: gender, age, surgery, chemotherapy agents, presence of chronic obstructive pulmonary disease (COPD), performance status. Dosimetric factors including prescribed dose (D iso ), presence of final conformal boost, mean lung dose (D mean ), % of lung receiving ≥20, 25, 30, 35, 40, and 45 Gy (respectively V 20 →V 45 ), and normal tissue complication probability (NTCP) values were analysed. DVHs data and NTCP values were collected for both lungs considered as a paired organ. Median and quartile values were taken as cut-off for statistical analysis. Factors that influenced RP were assessed by univariate (log-rank) and multivariate analyses (Cox hazard model). Results: There were 14 PTs (16.6%) who had ≥grade II pulmonary toxicity. In the entire population, the univariate analysis revealed that many dosimetric parameters (D iso , V 20 , V 30 , V 40 , V 45 ) were significantly associated with RP. No significant correlation was found between the incidence of RP and D mean or NTCP values. Multivariate analysis revealed that the use of mitomycin (MMC) (P=0.005) and the presence of COPD (P=0.026) were the most important risk factor for RP. In the group without COPD (55 PTs, seven RP) a few dosimetric factors (D mean , V 20 , V 45 ) and NTCP values (all models) were associated with RP in the univariate analysis

    A retrospective study was conducted to determine the importance of the interval between diagnosis of brain metastasis (BRM) and cranial irradiation (CI). The charts of 92 patients with a known diagnosis of cancer and suspected BRM as shown on radioimaging studies were reviewed retrospectively. The median interval between diagnosis and the onset of CI for BRM was five days; one group of 48 individuals received CI within an interval of five days, and another group of 44 patients after an interval of five days. Symptom palliation, objective responses to CI and survival were evaluated in both groups. Neither symptomatic and objective responses to treatment nor overall survival differed significantly between the patient groups. These observations suggest that while CI is beneficial to most patients with BRM, its timing after the diagnosis of BRM may not seriously affect patient outcome. (author)

    As access to antiretroviral therapy (ART) expands, increasing numbers of older patients will start treatment and need specialised long-term care. However, the effect of age in ART programmes in resource-constrained settings is poorly understood. The HIV epidemic is ageing rapidly and South Africa has one of the highest HIV population prevalences worldwide. We explored the effect of age on mortality of patients on ART in South Africa and whether this effect is mediated by baseline immunological status. In this retrospective cohort analysis, we studied HIV-positive patients aged 16-80 years who started ART for the first time in six large South African cohorts of the International Epidemiologic Databases to Evaluate AIDS-Southern Africa collaboration, in KwaZulu-Natal, Gauteng, and Western Cape (two primary care clinics, three hospitals, and a large rural cohort). The primary outcome was mortality. We ascertained patients' vital status through linkage to the National Population Register. We used inverse probability weighting to correct mortality for loss to follow-up. We estimated mortality using Cox's proportional hazards and competing risks regression. We tested the interaction between baseline CD4 cell count and age. Between Jan 1, 2004, and Dec 31, 2013, 84,078 eligible adults started ART. Of these, we followed up 83,566 patients for 174,640 patient-years. 8% (1817 of 23,258) of patients aged 16-29 years died compared with 19% (93 of 492) of patients aged 65 years or older. The age adjusted mortality hazard ratio was 2·52 (95% CI 2·01-3·17) for people aged 65 years or older compared with those 16-29 years of age. In patients starting ART with a CD4 count of less than 50 cells per μL, the adjusted mortality hazard ratio was 2·52 (2·04-3·11) for people aged 50 years or older compared with those 16-39 years old. Mortality was highest in patients with CD4 counts of less than 50 cells per μL, and 15% (1103 of 7295) of all patients aged 50 years or older

    Hong, Dae Seok; Lee, Kun Jai

    2003-01-01

    Electron Spin Resonance (ESR) spectroscopy is one of the methods applicable to retrospective dosimetry. The retrospective dosimetry is a part of dose reconstruction for estimation of exposed dose occurred years before the estimation. A tooth can be separated as enamel, dentine and cementum. Among the three parts, enamel is known as to show the best sensitivity to the absorbed dose and is most widely used. Since the later 80s, ESR dosimetry with tooth enamel has been studied and applied for the retrospective dosimetry. There are some factors affecting the sensitivity of enamel to absorbed dose. One of the factors is a size of enamel. Grain size of the 1.0mm∼0.1mm range is commonly used and 0.6mm∼0.25mm is recommended in other study. But the sensitivity can be varied by the grain size. In this study, the granular effect of enamel to the sensitivity is examined for application to retrospective dosimetry. In the enamel separation, to minimize the physically induced ESR spectrum, only chemical separation method was used. Separated enamels were divided by their size. The sizes of each sample is 1.0mm∼0.71mm, 0.5mm∼0.3mm, and below 0.1mm, respectively. All enamel samples show ESR spectrum related to the absorbed dose and the ESR spectrum shows linearity to the absorbed dose. The sensitivities are similar for each sample. But the enamel of size below 0.1mm shows poor characteristics relative to other enamel size. So, it is not recommended to use enamel samples below 0.1mm

    Full Text Available Schools, the where educational activities are carried out, are among the major institutions society considers as important. Schools undertake strategic responsibilities in maintaining cultural values and conveying them to future generations. The primary responsibility in achieving these missions is assigned to the school administrators. The purpose of this study is to determine the perceptions of school administrators on institutional culture. This is a qualitative study conducted on school administrators who were selected based on the volunteering principle. Perceptions of school administrators concerning their institutions’ culture and the differences between their institutional culture and other institution’s cultures were determined and analyzed. Findings of this study suggest that school administrators have both positive and negative opinions regarding their institutional culture and cultural difference. While love-respect, collaboration-solidarity and common history were prominent positive opinions; lack of communication, lack of shared values and low expectation were prominent negative opinions. In addition, participants stated the environment as a crucial factor when defining culture.

    Since mobile phones are always carried by individuals, the retrospective dosimetry using thermoluminescence (TL) and optically stimulated luminescence (OSL) characteristics of elements in mobile phone is intensively developing nowadays due to its advantages over conventional biological dosimetry techniques. Using a TL and OSL method on resistors and inductors in a mobile phone, a low background dose (zero dose) about tens of mGy is acquired in previous study. Radiation workers have to wear a dosimeter to assess individual exposure during their works. This monitoring system facilitate a fast medical treatment for highly exposed workers in case of a radiation accident. In the event of large-scale radiation accidents, where most of the subjects are ordinary people, it is difficult to evaluate the individual dose due to the absence of dosimeters. A technique for dose evaluation using a radiation dependency of various materials in the absence of a dosimeter is called retrospective dosimetry.

    Behavioral evidence from the young suggests spatial cues that orient attention toward task relevant items in visual working memory (VWM) enhance memory capacity. Whether older adults can also use retrospective cues (“retro-cues”) to enhance VWM capacity is unknown. In the current event-related potential (ERP) study, young and old adults performed a VWM task in which spatially informative retro-cues were presented during maintenance. Young but not older adults’ VWM capacity benefitted from retro-cueing. The contralateral delay activity (CDA) ERP index of VWM maintenance was attenuated after the retro-cue, which effectively reduced the impact of memory load. CDA amplitudes were reduced prior to retro-cue onset in the old only. Despite a preserved ability to delete items from VWM, older adults may be less able to use retrospective attention to enhance memory capacity when expectancy of impending spatial cues disrupts effective VWM maintenance.

    Dentistry is considered to be a stressful profession due to different factors caused by work, representing a threat to dentists'health. The objectives of this work were to identify and compare chronic stress in dentists among the different health institutions and the association of stress with risk factors. The study in question is observational, transversal and comparative; 256 dentists were included, distributed among five public health institutions in the city of Guadalajara, Jalisco, Mexico, namely: the Mexican Institute of Social Security (IMSS), the Ministry of Health (SS), the Integral Development of the Family (DIF), the Social Security Services Institute for the Workers (ISSSTE) and the University of Guadalajara (U. de G) Data were obtained by means of the census technique. Stress was identified using the Stress Symptoms Inventory and the statistical analysis was performed using the Odds Ratio (O.R.) and the chi-square statistic. From the total population studied, 219 subjects presented high levels of chronic stress and 37, low levels. In the results of comparative analysis, significant differences were found between IMSS and U. de G and likewise between IMSS and SS. However, in the analysis of association, only U. de G was found to be associated with the high level of chronic stress.

    2002-01-01

    To define a general methodology for maximising the success of follow-up processes for retrospective cohort studies in New Zealand, and to illustrate an approach to developing country-specific follow-up methodologies. We recently conducted a cohort study of mortality and cancer incidence in New Zealand professional fire fighters. A number of methods were used to trace vital status, including matching with records of the New Zealand Health Information Service (NZHIS), pension records of Work and Income New Zealand (WINZ), and electronic electoral rolls. Non-electronic methods included use of paper electoral rolls and the records of the Registrar of Births Deaths and Marriages. 95% of the theoretical person-years of follow-up of the cohort were traced using these methods. In terms of numbers of cohort members traced to end of follow-up, the most useful tracing methods were fire fighter employment records, the NZHIS, WINZ, and the electronic electoral rolls. The follow-up process used for the cohort study was highly successful. On the basis of this experience, we propose a generic, but flexible, model for follow-up of retrospective cohort studies in New Zealand. Similar models could be constructed for other countries. Successful follow-up of cohort studies is possible in New Zealand using established methods. This should encourage the use of cohort studies for the investigation of epidemiological issues. Similar models for follow-up processes could be constructed for other countries.

    2006-12-01

    A model for predicting student performance on introductory programming modules is presented. The model uses attributes identified in a study carried out at four third-level institutions in the Republic of Ireland. Four instruments were used to collect the data and over 25 attributes were examined. A data reduction technique was applied and a logistic regression model using 10-fold stratified cross validation was developed. The model used three attributes: Leaving Certificate Mathematics result (final mathematics examination at second level), number of hours playing computer games while taking the module and programming self-esteem. Prediction success was significant with 80% of students correctly classified. The model also works well on a per-institution level. A discussion on the implications of the model is provided and future work is outlined.

    In 1980 the New York Academy of Sciences sponsored a three-day conference on luminescence in biological and synthetic macromolecules. After that meeting, Professor Frans DeSchryver and I began to discuss the possibility of organizing a different kind of meeting, with time for both informal and in-depth discussions, to examine certain aspects of the application of fluorescence and phosphorescence spectroscopy to polymers. Our ideas developed through discussions with many others, particularly Professor Lucien Monnerie. By 1983, when we submitted our proposal to NATO for an Advanced Study Institute, the area had grown enormous ly. It is interesting in retrospect to look back on the points which emerged from these discussions as the basis around which the scientific program would be organized and the speakers chosen. We decided early on to focus on applications of these methods to provide information about polymer molecules and polymer systems: The topics would all relate to the conformation and dynamics of macro...

Nevertheless, a new tool is required for pain assessment needs in retrospective studies.Methods: The postoperative pain episodes, during the first postoperative day, of three patient groups were analyzed. Each pain episode was assessed by a visual analog scale, numerical rating scale, verbal rating scale, and a new tool – pain point system scale (PPSS – based on the analgesics administered. The type of analgesic was defined based on the authors’ clinic protocol, patient comorbidities, pain assessment tool scores, and preadministered medications by an artificial neural network system. At each pain episode, each patient was asked to fill the three pain scales. Bartlett’s test and Kaiser–Meyer–Olkin criterion were used to evaluate sample sufficiency. The proper scoring system was defined by varimax rotation. Spearman’s and Pearson’s coefficients assessed PPSS correlation to the known pain scales.Results: A total of 262 pain episodes were evaluated in 124 patients. The PPSS scored one point for each dose of paracetamol, three points for each nonsteroidal antiinflammatory drug or codeine, and seven points for each dose of opioids. The correlation between the visual analog scale and PPSS was found to be strong and linear (rho: 0.715; P <0.001 and Pearson: 0.631; P < 0.001.Conclusion: PPSS correlated well with the known pain scale and could be used safely in the evaluation of postoperative pain in retrospective studies.Keywords: pain scale, retrospective studies, pain point system

    Ceramic veneer fracture is a frequent complication in implant-borne fixed restorations. The retrospective clinical study assesses the effect of bruxism on this complication. A sample of 507 implant-borne fixed units inserted between 1995 and 2011 in 144 patients were examined. Any detected veneer fractures were assigned to one of four groups according to extent and position. A hypothetical correlation between bruxism and ceramic veneer fractures was examined. Of 34 patients (23.6%) with at least one ceramic veneer fracture, 24 were bruxers (70%) and 10 were nonbruxers (30%) (P = .002). Bruxism may pose a risk for ceramic fractures.

    Low-dose reactive wheat-allergic children are at a high risk of a positive oral food challenge (OFC). The present study aimed to evaluate whether the results of a very low-dose (VL) OFC would contribute to better wheat allergy management in this population. We retrospectively reviewed wheat-allergic subjects who underwent a VL OFC with 2 g of udon noodles (equivalent to 53 mg of wheat protein) and had a previous allergic reaction to management of some low-dose reactive wheat-allergic children from complete avoidance to partial wheat intake.

    Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

    The Essure(®) system is a hysteroscopic sterilization method. The aim of our study is to retrospectively evaluate the sterilization procedure with Essure(®) devices, with and without anesthesia, and in particular with hypnosis. The descriptive study includes all tubal sterilization with Essure(®) performed during the year 2009 at the Maternité régionale de Nancy. Hypnosis efficiency is retrospectively evaluated with Verbal Numeric Rating Scale (VNRS) for peroperative pain, and analgesic medication use for postoperative pain. Ninety-four sterilizations are performed, 85% (85/94) of them without anesthesia. The mean VNRS is 3.0. The mean operative time is 8.7 minutes, positively correlated with the VNRS (P=0.0005). The rate of successful insertion is 94%. At 3 months, 91% of the implants have a correct location. Inadequate locations are more frequent when anesthesia have been performed (37% vs 4%, P=0.016). There is no significant difference between groups with and without hypnosis for the VNRS, the failure rate and the use of analgesic medication. Tubal sterilization with the Essure(®) system is a quick and efficient method. Our study does not demonstrate efficiency of hypnosis in pain control. This remains to be explored with a prospective study, including others parameters, such as anxiety. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    As sagittal alignment of the cervical spine is important for maintaining horizontal gaze, it is important to determine the former for surgical correction. However, horizontal gaze remains poorly-defined from a radiological point of view. The objective of this study was to establish radiological criteria to define horizontal gaze. This study was conducted at a tertiary health-care institution over a 1-month period. A prospective cohort of healthy patients was used to determine the best radiological criteria for defining horizontal gaze. A retrospective cohort of patients without rigid spinal deformities was used to audit the incidence of horizontal gaze. Two categories of radiological parameters for determining horizontal gaze were tested: (1) the vertical offset distances of key identifiable structures from the horizontal gaze axis and (2) imaginary lines convergent with the horizontal gaze axis. Sixty-seven healthy subjects underwent whole-body EOS radiographs taken in a directed standing posture. Horizontal gaze was radiologically defined using each parameter, as represented by their means, 95% confidence intervals (CIs), and associated 2 standard deviations (SDs). Subsequently, applying the radiological criteria, we conducted a retrospective audit of such radiographs (before the implementation of a strict radioimaging standardization). The mean age of our prospective cohort was 46.8 years, whereas that of our retrospective cohort was 37.2 years. Gender was evenly distributed across both cohorts. The four parameters with the lowest 95% CI and 2 SD were the distance offsets of the midpoint of the hard palate (A) and the base of the sella turcica (B), the horizontal convergents formed by the tangential line to the hard palate (C), and the line joining the center of the orbital orifice with the internal occipital protuberance (D). In the prospective cohort, good sensitivity (>98%) was attained when two or more parameters were used. Audit using Criterion B

    the main objective was to evaluate if the admission functional independence measure (FIM) score could be used to predict the risk of falls in geriatric inpatients. a 10-year retrospective study was performed. the study was conducted in a 298-bed geriatric teaching hospital in Geneva, Switzerland. all patients discharged from the hospital from 1 January 1997 to 31 December 2006 were selected. measures used were FIM scores at admission using the FIM instrument and number of falls extracted from the institution's fall report forms. during the study period, there were 23,966 hospital stays. A total of 8,254 falls occurred. Of these, 7,995 falls were linked to 4,651 stays. Falls were recorded in 19.4% of hospital stays, with a mean incidence of 7.84 falls per 1,000 patients-days. Although there was a statistically significant relationship between total FIM score, its subscales, and the risk of falling, the sensitivity, specificity, positive predictive value and negative predictive value obtained with receiver operating characteristic curves were insufficient to permit fall prediction. This might be due in part to a non-linear relationship between FIM score and fall risk. in this study, the FIM instrument was found to be unable to predict risk of falls in general geriatric wards.

    Ghana has undertaken many public service management reforms in the past two decades. But the implementation of the reforms has been constrained by many factors. This paper undertakes a retrospective study of research works on the challenges to the implementation of reforms in the public health sector. It points out that most of the studies identified: (1) centralised, weak and fragmented management system; (2) poor implementation strategy; (3) lack of motivation; (4) weak institutional framework; (5) lack of financial and human resources and (6) staff attitude and behaviour as the major causes of ineffective reform implementation. The analysis further revealed that quite a number of crucial factors obstructing reform implementation which are particularly internal to the health system have either not been thoroughly studied or overlooked. The analysis identified lack of leadership; weak communication and consultation; lack of stakeholder participation, corruption and unethical professional behaviour as some of the missing variables in the literature. The study, therefore, indicated that there are gaps in the literature that needed to be filled through rigorous reform evaluation based on empirical research particularly at district, sub-district and community levels. It further suggested that future research should be concerned with the effects of both systems and structures and behavioural factors on reform implementation.

    Supratentorial ependymoma (STE) is a tumor whose unique clinical and imaging characteristics have not been studied. Histopathologically, they resemble ependymoma elsewhere. We retrospectively reviewed the imaging findings with clinicopathological correlation in a large number of patients with STE to identify these characteristics. Computed tomography (CT) magnetic resonance images (MRI), pathology reports, and clinical information from 41 patients with pathology-confirmed STE from a single institution were retrospectively reviewed. CT and MRI findings including location, size, signal intensity, hemorrhage, and enhancement pattern were tabulated and described separately in intraventricular and intraparenchymal forms. STE was more common in pediatric age group and intraparenchymal was more common than intraventricular form. The most common presentation was features of raised intracranial tension. There were equal numbers of Grade II and Grade III tumors. The imaging characteristics in adult and pediatric age group were similar. The tumor was large and had both solid and cystic components. Advanced imaging such as diffusion, perfusion, and spectroscopy were suggestive of high-grade tumor. Only differentiating factor between Grade II and Grade III was the presence of calcification. 1234 rule and periwinkle sign which we have described in this article may help characterize this tumor on imaging. This series expands the clinical and imaging spectrum of STE and identifies characteristics that should suggest consideration of this uncommon diagnosis.

    The management of malrotation in patients with congenital abdominal wall defects has varied among surgeons. We were interested in investigating the risk of midgut volvulus in patients with gastroschisis and omphalocele to help determine if these patients may benefit from undergoing a Ladd procedure. A retrospective chart review was performed for all patients managed at three institutions born between 1/1/2000 and 12/31/2008 with a diagnosis of gastroschisis or omphalocele. Patient charts were reviewed through 12/31/2012 for occurrence of midgut volvulus or need for second laparotomy. Of the 414 patients identified with abdominal wall defects, 299 patients (72%) had gastroschisis, and 115 patients (28%) had omphalocele. The mean gestational age at birth was 36.1±2.3weeks, and the mean birth weight was 2.57±0.7kg. There were a total of 8 (1.9%) cases of midgut volvulus: 3 (1.0%) patients with gastroschisis compared to 5 patients (4.4%) with omphalocele (p=0.04). Patients with omphalocele have a greater risk of developing midgut volvulus, and a Ladd procedure should be considered during definitive repair to mitigate these risks.

    Long thoracic nerve (LTN) injury can result in ipsilateral serratus anterior palsy and scapular winging. Traditional means of evaluating patients with suspected LTN injury include physical examination and electrodiagnostic studies. The purpose of our study is to describe high-resolution magnetic resonance (MR) findings in patients with clinical suspicion of LTN neuropathy. In this HIPAA-compliant, IRB-approved, retrospective study, two radiologists reviewed MR imaging performed for long thoracic neuropathy. Clinical presentation, electrodiagnostic studies and MR imaging of 20 subjects [mean age 37 ± 13 years; 25% (5/20) female] were reviewed. Observers reviewed MR imaging for LTN signal intensity, size, course, presence or absence of mass and secondary findings [skeletal muscle denervation (serratus anterior, trapezius, rhomboid) and scapular winging]. Descriptive statistics were reported. Clinical indications included trauma (n = 5), hereditary neuropathy (n = 1), pain (n = 8), winged scapula (n = 6), brachial plexitis (n = 4) and mass (n = 1). Electrodiagnostic testing (n = 7) was positive for serratus anterior denervation in three subjects. Abnormal LTN signal intensity, size, course or mass was present in 0/20. Secondary findings included skeletal muscle denervation in the serratus anterior in 40% (8/20), trapezius in 20% (4/20) and rhomboid in 20% (4/20). In 5% (1/20), an osteochondroma simulated a winged scapula, and in 2/20 (10%) MR showed scapular winging. High-resolution MR imaging is limited in its ability to visualize the long thoracic nerve directly, but does reveal secondary signs that can confirm a clinical suspicion of LTN injury. (orig.)

    The 1985 Castel vecchio-Pas coli NATO Advanced Study Institute is aimed to complete the trilogy with the two former institutes I organized : "Boundary Value Problem for Evolution Partial Differential Operators", Liege, 1976 and "Singularities in Boundary Value Problems", Maratea, 1980. It was indeed necessary to record the considerable progress realized in the field of the propagation of singularities of Schwartz Distri­ butions which led recently to the birth of a new branch of Mathema­ tical Analysis called Microlocal Analysis. Most of this theory was mainly built to be applied to distribution solutions of linear partial differential problems. A large part of this institute still went in this direction. But, on the other hand, it was also time to explore the new trend to use microlocal analysis In non linear differential problems. I hope that the Castelvecchio NATO ASI reached its purposes with the help of the more famous authorities in the field. The meeting was held in Tuscany (Italy) at Castelvecchio-P...

    2015-09-01

    Full Text Available Background: The modulation of adenosine receptors has been proposed as new therapeutic target for chronic obstructive pulmonary disease, but studies in humans were negative. Caffeine is widely consumed and acts by non-selective modulation of these receptors, allowing for a non-interventional evaluation of the purinergic effects on COPD. We evaluated the effects of chronic caffeine consumption on the risk for COPD exacerbations. Methods: Retrospective study including patients with COPD. The total number of exacerbations during a three-year period and the mean daily caffeine consumption in the last twenty years were evaluated. A univariate and multiple regression analysis were performed for evaluation of the significant predictors of exacerbations. Results: A total of 90 patients were included. Most were males (82.2% and had a mean forced expiratory volume in the first second (FEV1 of 57.0 ± 17.1% predicted. The mean daily caffeine consumption was 149.7 ± 140.9 mg. There was no correlation between the mean caffeine consumption and exacerbations (p > 0.05. Discussion: Our results suggest that caffeine has no significant effect on the frequency of COPD exacerbations. These conclusions are limited by the sample size and the retrospective nature of the study. Keywords: COPD, Caffeine, Disease exacerbation, Purines, Pharmacology, Coffee, Respiratory Tract Diseases

    Full Text Available Aim: Mortality rates are important outcome parameters after burn. The causes of mortality have been reported differently in the literature. The aim of the study was to identify parameters that are predictive of major morbidity factors and risk of mortality in patients with burn injury. Material and Methods: This study was performed among the patients who admitted to the burn center period between December 2001 and June 2010. Within this period, demographic data, treatment, and outcomes of treatment were reviewed and analyzed. Results: The burn patients were analysed retrospectively during 9-years period between December 2001 and January 2010. Burns caused by scalding were the most frequent (69.7 % followed by flames (24.4 %. 4.30 % of the patients died because of multisystem organ failure, septicaemia and cardiac respiratory failure. Conclusions:The most common cause of mortality was multiorgan failure according to our study. The mortality rates and causes of burn centers should be investigated retrospectively between different burn centres to determine the most common cause of mortality in burn centers.

    To investigate the correlation between the preoperative biometric parameters of the anterior segment and the vault after implantable Collamer lens (ICL) implantation via this retrospective study. Retrospective clinical study. A total of 78 eyes from 41 patients who underwent ICL implantation surgery were included in this study. Preoperative biometric parameters, including white-to-white (WTW) diameter, central corneal thickness, keratometer, pupil diameter, anterior chamber depth, sulcus-to-sulcus diameter, anterior chamber area (ACA) and central curvature radius of the anterior surface of the lens (Lenscur), were measured. Lenscur and ACA were measured with Rhinoceros 5.0 software on the image scanned with ultrasound biomicroscopy (UBM). The vault was assessed by UBM 3 months after surgery. Multiple stepwise regression analysis was employed to identify the variables that were correlated with the vault. The results showed that the vault was correlated with 3 variables: ACA (22.4 ± 4.25 mm2), WTW (11.36 ± 0.29 mm) and Lenscur (9.15 ± 1.21 mm). The regressive equation was: vault (mm) = 1.785 + 0.017 × ACA + 0.051 × Lenscur - 0.203 × WTW. Biometric parameters of the anterior segment (ACA, WTW and Lenscur) can predict the vault after ICL implantation using a new regression equation. © 2016 The Author(s) Published by S.

    Full Text Available INTRODUCTION Scorpions live in warm, dry regions throughout India. They inhabit commonly the crevices of dwellings, underground burrows, under logs or debris, paddy husk, sugar cane fields, coconut and banana. Scorpion stings are primarily due to accidental contact with scorpion. Konaseema region of Andhra Pradesh is delta of Godavari river. Because of good irrigation there is rich cultivation of banana and paddy and there are plenty of coconut plantations, so that is a good habitat for scorpions. METHOD Present study is a hospital based retrospective study. All the data related to the scorpion sting in Konaseema Institute of Medical Sciences admitted during Jan 2012 to Jan 2016 has been collected. RESULT Total 54 patients of all the age group and both the sexes were included in to the study. Out of 54 patients, 32 were male and 22 were female. Regarding signs of scorpion sting, tachycardia was present in 40 patients, ten patients developed hypertension. Six patients developed arrhythmia. Dyspnoea and convulsion was present in 6 and 2 patients respectively. DISCUSSION Scorpion venom is classified as per its structure, mode of action and binding site. Regarding complications of scorpion sting, four patients developed pulmonary oedema and 3 having convulsion. Out of all 54 patients, 53 were recovered and 1 patient died. CONCLUSION With the availability of potent vasodilators like prazosin and good ICU facilities, the incidence of death and complication due to scorpion bite has reduced.

    Medulloblastoma is associated with rare hereditary cancer predisposition syndromes; however, consensus medulloblastoma predisposition genes have not been defined and screening guidelines for genetic counselling and testing for paediatric patients are not available. We aimed to assess and define these genes to provide evidence for future screening guidelines. In this international, multicentre study, we analysed patients with medulloblastoma from retrospective cohorts (International Cancer Genome Consortium [ICGC] PedBrain, Medulloblastoma Advanced Genomics International Consortium [MAGIC], and the CEFALO series) and from prospective cohorts from four clinical studies (SJMB03, SJMB12, SJYC07, and I-HIT-MED). Whole-genome sequences and exome sequences from blood and tumour samples were analysed for rare damaging germline mutations in cancer predisposition genes. DNA methylation profiling was done to determine consensus molecular subgroups: WNT (MB WNT ), SHH (MB SHH ), group 3 (MB Group3 ), and group 4 (MB Group4 ). Medulloblastoma predisposition genes were predicted on the basis of rare variant burden tests against controls without a cancer diagnosis from the Exome Aggregation Consortium (ExAC). Previously defined somatic mutational signatures were used to further classify medulloblastoma genomes into two groups, a clock-like group (signatures 1 and 5) and a homologous recombination repair deficiency-like group (signatures 3 and 8), and chromothripsis was investigated using previously established criteria. Progression-free survival and overall survival were modelled for patients with a genetic predisposition to medulloblastoma. We included a total of 1022 patients with medulloblastoma from the retrospective cohorts (n=673) and the four prospective studies (n=349), from whom blood samples (n=1022) and tumour samples (n=800) were analysed for germline mutations in 110 cancer predisposition genes. In our rare variant burden analysis, we compared these against 53 105

    Full Text Available Abstract: The lack of guidelines for bone augmentation procedures might compromise decision making in implantology. The objective of this study was to perform a retrospective study to verify the outcomes of horizontal bone reconstruction in implant dentistry with different types of materials and amounts of native bone in the recipient bed to allow for a new guideline for horizontal bone reconstruction. One hundred preoperative CT scans were retrospectively evaluated and categorized in accordance to horizontal bone defects as presence (Group P or absence (Group A of cancellous bone in the recipient bed. Different approaches were used to treat the edentulous ridge and the outcomes were defined either as satisfactory or unsatisfactory regarding the possibility of implant placement. The percentage distribution of the patients according to the presence or absence of cancellous bone was 92% for Group P and 8% for Group A. In Group P, 98% of the patients had satisfactory outcomes, and the use of autografts had 100% of satisfactory outcomes in this group. In Group A, 37.5% of the patients had satisfactory outcomes, and the use of autografts also yielded 100% of satisfactory outcomes. The use of allografts and xenografts in Group A had 0% and 33.3% of satisfactory outcomes, respectively. Therefore, it seems reasonable to speculate that the presence of cancellous bone might be predictive and predictable when the decision includes bone substitutes.

    Polycystic ovary syndrome is characterized by irregular cycles, hyperandrogenism, polycystic ovary at ultrasound and insulin resistance. The effectiveness of D-chiro-inositol (DCI) treatment in improving insulin resistance in PCOS patients has been confirmed in several reports. The objective of this study was to retrospectively analyze the effect of DCI on menstrual cycle regularity in PCOS women. This was a retrospective study of patients with irregular cycles who were treated with DCI. Of all PCOS women admitted to our centre, 47 were treated with DCI and had complete medical charts. The percentage of women reporting regular menstrual cycles significantly increased with increasing duration of DCI treatment (24% and 51.6% at a mean of 6 and 15 months of treatment, respectively). Serum AMH levels and indexes of insulin resistance significantly decreased during the treatment. Low AMH levels, high HOMA index, and the presence of oligomenorrhea at the first visit were the independent predictors of obtaining regular menstrual cycle with DCI. In conclusion, the use of DCI is associated to clinical benefits for many women affected by PCOS including the improvement in insulin resistance and menstrual cycle regularity. Responders to the treatment may be identified on the basis of menstrual irregularity and hormonal or metabolic markers.

    Aspergillus spp. are saprophytic opportunistic fungal organisms and are a common cause of otomycosis in humans. Although there have been case reports of Aspergillus otitis externa in dogs, to the best of the authors' knowledge, this is the first retrospective case series describing Aspergillus otitis in dogs and cats. To characterize signalment, putative risk factors, treatments and outcomes of a case series of dogs and cats with Aspergillus otitis. Eight dogs and nine cats diagnosed with Aspergillus otitis. A retrospective review of medical records from 1989 to 2014 identified animals diagnosed with Aspergillus otitis based on culture. All dogs weighed greater than 23 kg. The most common putative risk factors identified in this study were concurrent diseases, therapy causing immunosuppression or a history of an otic foreign body. Aspergillus otitis was unilateral in all study dogs and most cats. Concurrent otitis media was confirmed in three dogs and one cat, and suspected in two additional cats. Aspergillus fumigatus was the most common isolate overall and was the dominant isolate in cats. Aspergillus niger and A. terreus were more commonly isolated from dogs. Animals received various topical and systemic antifungal medications; however, otic lavage under anaesthesia and/or surgical intervention increased the likelihood of resolution of the fungal infection. Aspergillus otitis is uncommon, typically seen as unilateral otitis externa in cats and larger breed dogs with possible risk factors that include immunosuppression and otic foreign bodies; previous antibiotic usage was common. © 2015 ESVD and ACVD.

  10. Human papillomavirus infection in Rio de Janeiro, Brazil: a retrospective study

    M.O.O Carvalho

    Full Text Available There is considerable data to support a central role for human papillomavirus (HPV in the etiology of cervical cancer. More than a 100 HPV types have been described, and 40 have been isolated from benign and malignant genital lesions. Consequently, there is strong motivation to evaluate HPV testing for cervical cancer screening. Few studies concerning the natural history of HPV infection have been conducted in the state of Rio de Janeiro. We determined the prevalence of HPV types in female genital lesions by using Hybrid Capture Assay (HCA and we retrospectively analyzed the course of HPV infection. Our sample included 788 women attended at Laboratórios Sérgio Franco. The average age of the participants was 29.6 years. HPV prevalence and cytological diagnosis were determined. The overall prevalence of HPV DNA in the study group was 50.1% (395/788, ranging from 25% (NORMAL to 100% in high-grade intraepithelial lesions (HSIL. High risk HPV was found in 12% inflammatory, 58.3% HPV, 63.2% LSIL and 100% HSIL. A retrospective analysis of 78 patients showed that 22 presented persistent lesions, 2 had progressive lesions, 4 had regressive lesions, 13 showed latent infections, 18 were transiently infected and 19 were submitted to curative treatment. No cases of cancer were registered in this population, which can afford private medical care and regular follow-up exams. We suggest that HCA be used in specific cases involving persistent and recurrent lesions.

    To compare levels of bilirubin (using the area under the curve, AUC) in preterm infants before the onset of sepsis with healthy matched-controls. Preterm infants born between January 2011 and December 2015 with late-onset sepsis were enrolled in our retrospective study and were matched with healthy controls (sex, birth weight and gestational age). Levels of bilirubin were registered in the eight days preceding the onset of sepsis and the AUC was calculated for both groups. Eighty-eight neonates (44 cases) were studied. GA and BW did not differ between cases and controls. In cases, we found a higher value of AUC (30.7 versus 22.5; p = 0.021). In our retrospective cohort, we found that the levels of bilirubin and the AUC in the first eight days before the onset of sepsis in preterm infants were significantly higher than the healthy controls. These data suggest that the prolonged exposition to high levels of bilirubin could increase the infection susceptibility in preterm infants.

    The need for totally implantable central venous access devices (TICVADs) has increased with increased opportunities in the use of chemotherapy and parenteral nutrition. This study aimed to determine the outcomes of TICVAD implantation and use in patients aged ≥85 years. Between January 2010 and August 2016, 117 patients underwent TICVAD implantation and their records were retrospectively reviewed. Participants were divided into 2 groups (plus-85 and sub-85 groups). Fifty-five patients (47.0%) had solid organ cancer alone; 35 patients (29.9%) had cerebrovascular or cranial nerve disease. The average follow-up period was 201 (2-1,620) days. Major complications were identified in 6 (14.6%) plus-85 patients and 11 (14.5%) sub-85 patients (p = 0.9813). Catheter-related infections developed in 3 plus-85 (7.3%) and 4 sub-85 patients (5.3%; p = 0.6549). There were no significant group differences in hematoma, pneumothorax, occlusion, and removal rates. In plus-85 patients examined just before surgery and a month after surgery, increased rates of serum albumin and Onodera's prognostic nutritional index were observed in 48% (14/39) and 41% (12/39), respectively. The use of TICVADs in the plus-85 group resulted in effective outcomes. The results of this retrospective study support the wider use of TICVADs in patients aged ≥85 years. © 2018 S.

    A body of evidence supports the use of low tidal volumes in ventilated patients without lung pathology to slow progress to acute respiratory distress syndrome (ARDS) due to ventilator associated lung injury. We undertook a retrospective chart review and tested the hypothesis that tidal volume is a predictor of mortality in cardiothoracic (medical and surgical) critical care patients receiving invasive mechanical ventilation. Independent predictors of mortality in our study included: type of surgery, albumin, H + , bilirubin, and fluid balance. In particular, it is important to note that cardiac, thoracic, and transplant surgical patients were associated with lower mortality. However, our study did not sample equally from The Berlin Definition of ARDS severity categories (mild, moderate, and severe hypoxemia). Although our study was not adequately powered to detect a difference in mortality between these groups, it will inform the development of a large prospective cohort study exploring the role of low tidal volume ventilation in cardiothoracic critically ill patients.

    2016-06-01

    Full Text Available Institutional Social responsibility (ISR in context to a Higher Educational Institution has been defined as the ethical practice in transference of knowledge, and the active participation in betterment of quality of life in the society. It is an offshoot of the concept of Corporate Social responsibility (CSR, but unlike CSR, it is neither mandatory nor actively monitored or researched in Indian context. However, awareness towards aspects of ISR has been increasing, especially in Indian Universities. Indian Universities adopt practices related to Adoption of Villages, Awareness Drives, Environmental Care and rural Education initiatives. Critics often see ISR as an unnecessary burden; review of literature from around the world suggests that ISR practices contribute to increased accountability towards exploitation of resources by Educational Institutes as well as better reputation of Educational Institutes in the society. The purpose of this paper is to examine the perception towards the concept of ISR in Educational Institutes in India. The paper opted for a questionnaire-based exploratory survey of 50 faculty members, across Private Universities in Rajasthan. The findings suggest lacking awareness but a significant acceptance of need of ISR practices. The paper includes implications for the Universities to include ISR practices in their strategy to address its obligations to the society and simultaneously gain a competitive advantage.

    The United States' position in the global economy requires an influx of women into science, technology, engineering, and mathematics (STEM) fields in order to remain competitive. Despite this, the representation of women in STEM continues to be low. The National Science Foundation's ADVANCE Program addresses this issue by funding projects that aim to increase the representation of women in academic STEM fields through transformation of institutional structures that impede women's progress in academic STEM fields. This paper includes a case study of the Texas A&M University ADVANCE Program.

    Initial approaches to and treatments of infants with Robin sequence (RS) is diverse and inconsistent. The care of these sometimes critically ill infants involves many different medical specialties, which can make the decision process complex and difficult. To optimize the care of infants with RS, we present our institution's approach and a review of the current literature. A retrospective cohort study was conducted among 75 infants diagnosed with RS and managed at our institution in the 1996-2012 period. Additionally, the conducted treatment regimen in this paper was discussed with recent literature describing the approach of infants with RS. Forty-four infants (59%) were found to have been treated conservatively. A significant larger proportion of nonisolated RS infants than isolated RS infants needed surgical intervention (53 vs. 25%, p = .014). A mandibular distraction was conducted in 24% (n = 18) of cases, a tracheotomy in 9% (n = 7), and a tongue-lip adhesion in 8% (n = 6). Seventy-seven percent of all infants had received temporary nasogastric tube feeding. The literature review of 31 studies showed that initial examinations and the indications to perform a surgical intervention varied and were often not clearly described. RS is a heterogenic group with a wide spectrum of associated anomalies. As a result, the decisional process is challenging, and a multidisciplinary approach to treatment is desirable. Current treatment options in literature vary, and a more uniform approach is recommended. We provide a comprehensive and pragmatic approach to the analysis and treatment of infants with RS, which could serve as useful guidance in other clinics.

    Imatinib is a cornerstone of treatment of chronic myeloid leukemia. It remains unclear whether transient treatment discontinuation or dose changes affect outcome and this approach has not yet been approved for use outside clinical trials. We conducted a retrospective single-institution observational study to evaluate factors affecting response in 'real-life' clinical practice in 138 chronic myeloid leukemia patients in chronic phase treated with imatinib. We used a novel longitudinal data analytical model, with a generalized estimating equation model, to study BCR-ABL variation according to continuous standard dose, change in dose or discontinuation; BCR-ABL transcript levels were recorded. Treatment history was subdivided into time periods for which treatment was given at constant dosage (total 483 time periods). Molecular and cytogenetic complete response was observed after 154 (32%) and 358 (74%) time periods, respectively. After adjusting for length of time period, no association between dose and cytogenetic complete response rate was observed. There was a significantly lower molecular complete response rate after time periods at a high imatinib dosage. This statistical approach can identify individual patient variation in longitudinal data collected over time and suggests that changes in dose or discontinuation of therapy could be considered in patients with appropriate biological characteristics.

    Ectodermal dysplasias form a complex, nosologic group of diseases with defects in at least 2 ectodermal structures. A retrospective study of patients with ectodermal dysplasia seen at our department over a period of 19 years (1994-2013) was performed. The study population consisted of 67 patients covering 17 different diagnoses. Forty-five families were identified of which 26 were sporadic cases with no affected family members. In 27 tested families a disease-causing mutation was identified in 23 families. Eleven mutations were novel mutations. To our knowledge, we present the first large ectodermal dysplasia cohort focusing on clinical manifestations in combination with mutational analysis. We recommend a nationwide study to estimate the prevalence of the ectodermal dysplasia and to ensure relevant molecular genetic testing which may form the basis of a national ectodermal dysplasia database.

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children.

    The impact of dermatology consultation on the care of children with oncologic conditions is unknown. To review outpatient dermatology visits and the resulting impact on diagnosis and management of pediatric oncology patients. Retrospective review of pediatric oncology patients with outpatient dermatology visits at a tertiary care center from 2008 to 2015. The most common dermatologic diagnoses in 516 patients were skin infections (21.3%) and nonmalignant skin eruptions (33.4%). A diagnosis of significant impact (ie, malignancy, adverse cutaneous drug reaction, graft-versus-host disease, varicella-zoster virus, or herpes simplex virus infection), was made at the dermatology clinic in 14.7% of visits. Consultation resulted in a change in diagnosis in 59.8% of patients, change in dermatologic management in 72.4% of patients, and change in management of noncutaneous issues in 12.4% of patients. The use of electronic medical records, the nongeneralizable study population, and the retrospective design represent potential limitations. Outpatient dermatology consultation can affect the care of pediatric oncology patients with respect to diagnosis and treatment of skin conditions and management of nondermatologic issues.

    Interactive Metronome (IM, The Interactive Metronome Company, Sunrise, Florida, USA) is a computer-based modality marketed to rehabilitation professionals who want to improve outcomes in areas of coordination, motor skills, self-regulation behaviors, and cognitive skills. This retrospective study examined the efficacy of IM training on improving timing skills, hand function, and parental report of self-regulatory behaviors. Forty eight children with mixed motor and cognitive diagnoses completed an average of 14 one-hour training sessions over an average of 8.5 weeks in an outpatient setting. Each child was assessed before and after training with the Interactive Metronome Long Form Assessment, the Jebsen Taylor Test of Hand Function, and a parent questionnaire. All three measures improved with statistical significance despite participants having no direct skill training. These results suggest an intimate relationship between cognition and motor skills that has potential therapeutic value. Level 4, Retrospective Case Series. Copyright © 2015 Hanley & Belfus.

    Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit. Patient demographics, procedures, and wound infection rates were analyzed using descriptive statistics, and risk factors were analyzed using logistic regression analyses. Twenty-six patients (2.81%) experienced acute surgical site infection following lumbar surgery in our study. The patients' mean body mass index, smoking history, operative time, blood loss, draining time, and drainage volume in the acute surgical site infection group were significantly different from those in the non-acute surgical site infection group (p operative type in the acute surgical site infection group were significantly different than those in the non-acute surgical site infection group (p operative type, operative time, blood loss, and drainage time were independent predictors of acute surgical site infection following lumbar surgery. In order to reduce the risk of infection following lumbar surgery, patients should be evaluated for the risk factors noted above.

    2017-01-01

    Aims: Head and neck carcinomas are relatively rare in the United Kingdom with an estimated 9000 cases diagnosed annually. However, pain associated with disease and treatment side effects such as oral mucositis present a major issue for therapy radiographers in providing effective care and maintaining radiotherapy treatment compliance, all factors that can compromise patient outcome if not managed appropriately. Method: This retrospective analysis of self-reporting pain scores collected during a course of radiotherapy aims to assess the perceived pain intensity scores in 30 patients. Data was collected during radiographer review sessions held weekly to determine if any variables to perceived pain scores occurred during a course of radiotherapy. Results: As treatment progressed, the self-reporting pain scores within the cohort increased, in week one the total cohort pain score was 35, this increased to 114 in week 3 and in the final week had totalled 151. An escalation in pain was observed in week 3 of treatment possibly as a result of radiation induced inflammation alongside cytotoxic chemotherapy. Conclusions: The findings of this study provide further evidence to an individualised approach to patient pain relief and providing regular on treatment reviews, thus maintaining patient comfort and ensuring continued treatment compliance. - Highlights: • Pain is an important but too infrequently analysed symptom in head and neck cancer. • As treatment progressed, the self-reporting pain scores within the cohort increased. • These findings provide the rationale for an individualised approach to pain relief. • Ensuring adequate pain control can positively influence continued treatment compliance.

    The 2014 west African epidemic of Ebola virus disease posed a major threat to the health systems of the countries affected. We sought to quantify the consequences of Ebola virus disease on maternal and child health services in the highly-affected Forest region of Guinea. We did a retrospective, observational cohort study of women and children attending public health facilities for antenatal care, institutional delivery, and immunisation services in six of seven health districts in the Forest region (Beyla, Guéckédou, Kissidougou, Lola, Macenta, and N'Zérékoré). We examined monthly service use data for eight maternal and child health services indicators: antenatal care (≥1 antenatal care visit and ≥3 antenatal care visits), institutional delivery, and receipt of five infant vaccines: polio, pentavalent (diphtheria, tetanus, pertussis, hepatitis B virus, and Haemophilus influenzae type b), yellow fever, measles, and tuberculosis. We used interrupted time series models to estimate trends in each indicator across three time periods: pre-Ebola virus disease epidemic (January, 2013, to February, 2014), during-epidemic (March, 2014, to February, 2015) and post-epidemic (March, 2015, to Feb, 2016). We used segmented ordinary least-squares (OLS) regression using Newey-West standard errors to accommodate for serial autocorrelation, and adjusted for any potential effect of birth seasonality on our outcomes. In the months before the Ebola virus disease outbreak, all three maternal indicators showed a significantly positive change in trend, ranging from a monthly average increase of 61 (95% CI 38-84) institutional deliveries to 119 (95% CI 79-158) women achieving at least three antenatal care visits. These increasing trends were reversed during the epidemic: fewer institutional deliveries occurred (-240, 95% CI -293 to -187), and fewer women achieved at least one antenatal care visit (-418, 95% CI -535 to -300) or at least three antenatal care visits (-363, 95% CI -485

    2015-01-01

    For a child, the likelihood of being murdered is highest during the first year of life, and many such cases are neonaticides. Although several recent studies have examined neonaticide in different countries and cultures, there has been no in-depth analysis of Swiss cases, even though this country has special neonaticide legislation and four "baby hatches" have been opened to prevent such killings. The primary objective of this retrospective study was to analyze the prevalence and phenomenon of neonaticide in Switzerland. Using data from judicial files, 11 cases were identified in 15 German-speaking cantons between 1980 and 2010. The sample included two uncommon cases of nonmaternal neonaticide. The discussion addresses possible prevention strategies.

    Acupuncture is a promising option in the treatment of functional bowel disorders. The aim of this study was to evaluate the feasibility and acceptance of acupuncture for the treatment of hospital-induced constipation (HIC) in children. Bilateral stimulation of acupuncture point LI11 was applied in 10 children with HIC using fixed indwelling acupuncture needles (0.9 mm long) before considering starting conventional local constipation therapy with laxative suppositories. The clinical records were studied retrospectively for feasibility, acceptance and effectiveness of acupuncture. Acupuncture was feasible in all children and application of the indwelling needles was tolerated without fear. Side effects were not observed. After a median of 3 days of HIC, all children defaecated within 2 h after LI11 stimulation. No patient required conventional local constipation therapy. Acupuncture for the treatment of HIC is feasible and acceptable. Its effect should be verified in a randomised controlled trial.

    2012-01-31

    The objective of this 10 year, retrospective study is to evaluate the indications for the removal of titanium miniplates following osteosynthesis in maxillofacial trauma and orthognathic surgery. All patients who had miniplates placed in a Regional Oral and Maxillofacial Department between January 1998 and October 2007 were included. The following variables were recorded: patient gender and age, number of plates inserted, indications for plate placement, location of plates, number and location of plates removed, indications for plate removal, time between insertion and removal, medical co-morbidities, and the follow-up period. During the 10 years of the study, 1247 titanium miniplates were placed in 535 patients. A total of 32 (3%) plates were removed from 30 patients. Superficial infection accounted for 41% of all plates removed. All complications were minor and most plates were removed within the first year of insertion. A low removal rate of 3% suggests that the routine removal of asymptomatic titanium miniplates is not indicated.

    Full Text Available The article investigates attitudes towards English as a foreign language (EFL by focusing on retrospective accounts of higher-education students’ experience with learning English. The first part looks at individual factors affecting foreign language (FL learning, such as attitudes towards FL learning and FL anxiety. The second part presents the results of a study conducted among students of the Faculty of Health Sciences at the University of Primorska. The main aim of the study was to identify students’ attitudes towards their past EFL lessons and teachers and students’ FL anxiety level. The results show that anxiety is a serious problem and that students exhibit alarmingly negative attitudes towards EFL lessons and teachers.

    BACKGROUND: The use of continuous glucose monitoring (CGM) in clinical decision making in diabetes could be limited by the inaccuracy of CGM data when compared to plasma glucose measurements. The aim of the present study is to investigate the impact of CGM numerical accuracy on the precision...... of diabetes treatment adjustments. METHOD: CGM profiles with maximum 5-day duration from 12 patients with type 1 diabetes treated with a basal-bolus insulin regimen were processed by 2 CGM algorithms, with the accuracy of algorithm 2 being higher than the accuracy of algorithm 1, using the median absolute...... of the interclinician agreement and the intraclinician reproducibility of the decisions. The Cohen's kappa coefficient was used to assess the precision of the decisions. The study was based on retrospective and blind CGM data. RESULTS: For the interclinician agreement, in the first occasion, the kappa of algorithm 1...

    The aetiology of status asthmaticus (SA), a complication of severe asthma, is unknown. Fungal exposure, as measured by fungal atopy, is a major risk factor for developing asthma, but the relationship of fungi in SA per se has not previously been reported. In this five patient retrospective case series study, lower respiratory tract cultures were performed on bronchoalveolar lavage or tracheal aspirate fluid, comparing standard clinical laboratory cultures with a specialized technique in which respiratory mucus was removed prior to culture. We show mucolytic treatment allows increased detection of fungal growth, especially yeast, from the lower airways of all SA patients. We also demonstrate that the yeast Candida albicans inhalation readily induces asthma-like disease in mice. Our observations suggest, SA may represent a fungal infectious process, and supports additional prospective studies utilizing anti-fungal therapy to supplement conventional therapy, broad-spectrum antibiotics and high-dose glucocorticoids, which can promote fungal overgrowth.

    About 40% of the general population report dyspepsia at some time in their life making it a fairly common disease. Uncomplicated dyspepsia refers to patients whose dyspepsia is not accompanied by alarm features or associated with NSAIDS usage. To assess the need for UGI Endoscopy and find out the patterns of different endoscopic presentations in patients presenting with uncomplicated dyspepsia. Our study conducted in KR Hospital, Mysore, Department of General Surgery is a retrospective endoscopic study of 1450 patients with uncomplicated dysepsia. A significant 64% of the patients presenting with uncomplicated dyspepsia were found to have findings on endoscopy. The most common age range for positive endoscopic findings was 40-50 years in our hospital. Malignancy was diagnosed in 2.5% patients. We recommend upper GI endoscopy in patients presenting with uncomplicated dyspepsia for patients above 40 years of age in our hospital.
