Skin cancer is rare among Africans and albinism is an established risk for skin cancer in this population. Ultraviolet radiation is highest at the equator and African albinos living close to the equator have the highest risk of developing skin cancers. This was a retrospective study that involved histological review of all specimens with skin cancers from African albinos submitted to The Regional Dermatology Training Center in Moshi, Tanzania from 2002 to 2011. A total of 134 biopsies from 86 patients with a male to female ratio of 1:1 were reviewed. Head and neck was the commonest (n = 75, 56.0%) site affected by skin cancers. Squamous cell carcinoma (SCC) was more common than basal cell carcinoma (BCC) with a ratio of 1.2:1. Only one Acral lentiginous melanoma was reported. Majority (55.6%) of SCC were well differentiated while nodular BCC (75%) was the most common type of BCC. Squamous cell carcinoma is more common than basal cell carcinoma in African albinos

Is dream recall underestimated by retrospective measures and enhanced by keeping a logbook? A review.

There are two methods commonly used to measure dream recall in the home setting. The retrospective method involves asking participants to estimate their dream recall in response to a single question and the logbook method involves keeping a daily record of one's dream recall. Until recently, the implicit assumption has been that these measures are largely equivalent. However, this is challenged by the tendency for retrospective measures to yield significantly lower dream recall rates than logbooks. A common explanation for this is that retrospective measures underestimate dream recall. Another is that keeping a logbook enhances it. If retrospective measures underestimate dream recall and if logbooks enhance it they are both unlikely to reflect typical dream recall rates and may be confounded with variables associated with the underestimation and enhancement effects. To date, this issue has received insufficient attention. The present review addresses this gap in the literature. Copyright © 2015 Elsevier Inc. All rights reserved.

Multicenter retrospective case series. To determine the rate of thoracic duct injury during cervical spine operations. A retrospective case series study was conducted among 21 high-volume surgical centers to identify instances of thoracic duct injury during anterior cervical spine surgery. Staff at each center abstracted data for each identified case into case report forms. All case report forms were collected by the AOSpine North America Clinical Research Network Methodological Core for data processing, cleaning, and analysis. Of a total of 9591 patients reviewed that underwent cervical spine surgery, 2 (0.02%) incurred iatrogenic injury to the thoracic duct. Both patients underwent a left-sided anterior cervical discectomy and fusion. The interruption of the thoracic duct was addressed intraoperatively in one patient with no residual postoperative effects. The second individual developed a chylous fluid collection approximately 2 months after the operation that required drainage via needle aspiration. Damage to the thoracic duct during cervical spine surgery is a relatively rare occurrence. Rapid identification of the disruption of this lymphatic vessel is critical to minimize deleterious effects of this complication.

Lawn mower injuries occur frequently in the United States and oftentimes result in extensive trauma to the lower extremities. These injuries can be quite devastating and cause there to be loss of function and amputation. The purpose of this study was to determine if there are specific factors that would help determine the best treatment protocol, patient outcomes, and prognosis after lawn mower injury to the foot and ankle. A retrospective review of medical records was performed on all patients treated at a university level 1 trauma center from 2000 to 2010. Only subjects 18 years or older who sustained an injury below the level of the knee were included for review. Seventy-three patients were included in this review. The results revealed that patients who developed a complication were significantly older than the group of patients without complications (P = .03). Digits were found to be injured most often but the odds of developing a complication were much higher if these injuries involved the plantar foot, dorsal foot, or ankle. Interestingly, patients on prolonged antibiotic therapy had a significantly higher risk of developing complications. The presence of comorbidities significantly increased the risk of complication (P = .008); the greatest risk factors were cardiovascular disease (P = .001) and diabetes (P = .06). The authors present the largest cohort of lawn mower injuries in the medical literature, which demonstrates that factors such as age, location of injury, and the presence of comorbidities influence the outcome and increase the risk of injury to the foot and ankle. These results may be useful in determining the best treatment plan possible for patients with these severe injuries. Therapeutic, Level IV, Retrospective case series.

Prescription opioids (PO) addiction is increasing to an epidemic level. Few studies exist regarding its treatment. Although buprenorphine has been the mainstay so far, other treatment options might be considered, such as methadone. We conducted a retrospective assessment of all patients admitted to a psychiatry ward for PO detoxification using methadone between 2010 and 2013. The assessment and description was carried out during a 3-month follow-up period after their discharge. Although this is a retrospective chart review, our exploration included sociodemographic and treatment variables in addition to the abstinence rates for the whole sample. Eleven patients were included, mostly women (81.8%), with a median age of 50 years. The median duration of dependence was 8 years. Dependence on other substances and psychiatric comorbidities were high. Eight patients were monitored during three months. Of these, 7 (87.5%) were abstinent after that period. The results suggest that methadone deserves further exploration as a potentially efficacious treatment option for PO dependence.

Although total hip arthroplasty is one of the most common orthopaedic surgical procedures, it remains unclear whether histopathological examination of the excised femoral head adds to the quality of patient care. We propose that assessment of femoral heads resected during total hip arthroplasty and donated for allograft use may provide a profile of femoral head pathology that benefits total hip arthroplasty patients and bone donors. We retrospectively analyzed the histological findings reported for 6161 femoral heads donated for allograft use between 1993 and 2006. Specimens obtained during total hip arthroplasty and specimens donated at death were reviewed. Follow-up investigations that resulted from abnormal histopathological findings were also reviewed. The Western Australian Cancer Registry was used to determine whether patients with a suspected neoplasm were subsequently diagnosed with such a disease. A retrospective review of the histopathological findings was conducted to evaluate and reclassify all previous observations of abnormalities. One hundred and five femoral heads demonstrated abnormal or reactive histopathological features not reported prior to surgery and were rejected for allograft use. A reactive lymphocytic infiltrate, most likely due to osteoarthritis, was the most commonly identified feature (forty-five cases). Other features observed in twenty-seven cases were also most likely due to the presence of severe osteoarthritis. Ten femoral heads demonstrated plasmacytosis, which may have been related to osteoarthritis. Two patients were diagnosed with Paget's disease, and two, with rheumatoid arthritis. Nineteen patients had a suspected neoplasm. Of these nineteen, eight cases of non-Hodgkin's lymphoma or chronic lymphocytic leukemia and one case of myelodysplastic syndrome were confirmed on further investigation. One subsequently confirmed malignancy was detected per 770 femoral heads examined. Our findings indicate that, even with a detailed

Suicide in Pretoria: A retrospective review, 2007 - 2010

Directory of Open Access Journals (Sweden)

Cornelia Engelbrecht

2017-08-01

Full Text Available Background. The World Health Organization has declared suicide a global ealth crisis, predicting that ~1.53 million people will commit suicide annually by 2020. Objective. A study from South Africa reviewed 1 018 suicide cases in Pretoria over 4 years (1997 - 2000. Our study was undertaken to establish whether there have been substantial changes in the profile of suicide victims who died in Pretoria a decade later. Methods. Case records at the Pretoria Medico-Legal Laboratory were reviewed retrospectively from 2007 to 2010. Results. A total of 957 suicide cases were identified. Hanging was the most common method of suicide, followed by self-inflicted firearm injury. The true incidence of suicidal intake of prescription drugs/medication was difficult to determine, because of a backlog at the state toxicology laboratories. White males and females appeared to be over-represented among suicide victims, but there has been an increase in suicide among blacks. There seems to have been a substantial decrease in the use of firearms to commit suicide – possibly reflecting a positive outcome of gun control legislation that has been introduced in the interim. Conclusion. Suicide continues to constitute almost 10% of all fatalities admitted to the Pretoria Medico-Legal Laboratory, confirming suicide as a major cause of mortality in our society. Further research is needed to clarify the profile of suicidal deaths, with a view to informing resource allocation and to improve preventive strategies.

Objective: literature review and case histories. Neuroendocrine tumors (Nets) are considered rare and comprise a group very heterogeneous with different prognosis and evolution. They represent less than 1% of all malignant tumors and most originate from the gastrointestinal tract in enterocromoafines cells are widely distributed in the same: in the stomach, duodenum, pancreas, small, colon and rectum. Carcinoid tumors Gastrointestinal represent over 70% of all tumors (Nets) in humans. And frequently they are finding their debut as disseminated disease, coinciding our review. 21 records were retrospectively analyzed between 1995 and June 2010. No significant difference in gender, of these 9 patients were 12 female and male sex. Ages ranged from 36 years to 83 years, with an average of 63 years. The locations were distributed as follows: 6 patients with small bowel tumor, 2 with blind tumor, 2 esophageal tumor , 1 patient with pancreatic tumor, 1 patient with stomach tumor, 2 patients with retroperitoneal disease in which failed to define the primary, 2 patients with tumor in breast, 3 patients with lung tumor, 1 patient with piriform sinus tumor and 1 patient with parotid tumor. Of the 21 patients, only 4 sometime had functional syndrome characterized by diarrhea and flushing. The treatments that received these patients were also very heterogeneous. From these patients, only one died in 2008 and the others are still alive, some in control and other treatment. Because of the number of patients seen and the therapeutic variability the statistical analysis no was done

This study describes the burden of bleeding oesophageal varices at the main tertiary referral centre in Accra. Retrospective design to describe the endoscopic spectrum and review mortality data following acute upper gastro-intestinal bleeding at the Korle-Bu Teaching Hospital. Endoscopic data was reviewed in the Endoscopy Unit between 2007 and 2010. Mortality data was collated from the Department of Medicine between 2010 and 2013. The study questionnaire compiled clinical and demographic characteristics, endoscopic diagnoses, length of hospital admission and treatment regimens. Aetiology and time-trend analysis of mortality rates following acute upper gastro-intestinal bleeding; variceal bleeding treatment modalities. On review of the endoscopic diagnoses, gastro-oesophageal varices were identified in 21.9% of cases followed by gastritis 21.7%, duodenal ulcer, 17.0%, and gastric ulcer, 13.2%. Gastro-oesophageal varices were the predominant cause of death from acute upper gastro-intestinal haemorrhage from 46% in 2010 to 76% in 2013. Outcomes following acute upper gastro-intestinal bleeding were dismal with some 38% of fatalities occurring within the first 24 hours. Injection sclerotherapy was the dominant endoscopic modality for secondary prevention of variceal bleeding in comparison with band ligation, mainly as a result of cost and availability. At the tertiary centre in Accra, variceal bleeding is an increasingly common cause of acute upper gastro-intestinal haemorrhage in comparison with previous reviews in Ghana. Its significantly high in-hospital mortality reflects inadequate facilities to deal with this medical emergency. A strategic approach to care with endoscopic services equipped with all the necessary therapeutic interventions will be vital in improving the outcomes of variceal bleeding in Ghana.

Genital or vulval lichen planus (VLP) may have a disabling effect on a patient's quality of life. Evidence-based management guidelines are lacking for VLP. We sought to review clinical presentation and treatment of patients who received a diagnosis of VLP. The 100 consecutive patients who received a diagnosis of VLP at Mayo Clinic between January 1, 1997, and December 31, 2015, were reviewed retrospectively. Descriptive statistics were used for data analysis. Fisher's exact test and the Wilcoxon rank sum test were used for analysis of categorical and continuous variables, respectively. All statistical tests were 2 sided, with the α level set at .05 for statistical significance. The time to diagnosis for 49% of patients was more than 1 year. Three patients (3%) had vulval dysplasia, including invasive squamous cell carcinoma. Sixty-eight patients (68%) had multisite lichen planus disease. Eleven patients (11%) had disease remission. Dermatology was the lead specialty for 9 of these cases of remission. This was a retrospective, small-cohort study. A low frequency of disease remission was seen in patients with VLP. Patients with lichen planus benefit considerably from dermatology consultation. Further research is warranted to establish high-quality, evidence-based guidelines for multidisciplinary management of this challenging disease. Copyright © 2017 American Academy of Dermatology, Inc.

Retrospective and emergency dosimetry in response to radiological incidents and nuclear mass-casualty events: A review

International Nuclear Information System (INIS)

Bailiff, I.K.; Sholom, S.; McKeever, S.W.S.

2016-01-01

This paper reviews recent research on the application of the physical dosimetry techniques of electron paramagnetic resonance (EPR) and luminescence (optically stimulated luminescence, OSL, and thermoluminescence, TL) to determine radiation dose following catastrophic, large-scale radiological events. Such data are used in dose reconstruction to obtain estimates of dose due to the exposure to external sources of radiation, primarily gamma radiation, by individual members of the public and by populations. The EPR and luminescence techniques have been applied to a wide range of radiological studies, including nuclear bomb detonation (e.g., Hiroshima and Nagasaki), nuclear power plant accidents (e.g., Chernobyl), radioactive pollution (e.g., Mayak plutonium facility), and in the future could include terrorist events involving the dispersal of radioactive materials. In this review we examine the application of these techniques in ‘emergency’ and ‘retrospective’ modes of operation that are conducted on two distinct timescales. For emergency dosimetry immediate action to evaluate dose to individuals following radiation exposure is required to assess deterministic biological effects and to enable rapid medical triage. Retrospective dosimetry, on the other hand, contributes to the reconstruction of doses to populations and individuals following external exposure, and contributes to the long-term study of stochastic processes and the consequential epidemiological effects. Although internal exposure, via ingestion of radionuclides for example, can be a potentially significant contributor to dose, this review is confined to those dose components arising from exposure to external radiation, which in most studies is gamma radiation. The nascent emergency dosimetry measurement techniques aim to perform direct dose evaluations for individuals who, as members of the public, are most unlikely to be carrying a dosimeter issued for radiation monitoring purposes in the event

Malignant hyperthermia susceptibility in patients with exertional rhabdomyolysis: a retrospective cohort study and updated systematic review.

Two potentially fatal syndromes, malignant hyperthermia (MH), an adverse reaction to general anesthesia, and exertional rhabdomyolysis (ER) share some clinical features, including hyperthermia, muscle rigidity, tachycardia, and elevated serum creatine kinase. Some patients with ER have experienced an MH event and/or have been diagnosed as MH susceptible (MHS). In order to assess the relationship between ER and MH further, we conducted a retrospective cohort study summarizing clinical and genetic information on Canadian patients with ER who were diagnosed as MHS. In addition, a systematic literature review was performed to compile further evidence on MH susceptibility and RYR1 and CACNA1S variants associated with rhabdomyolysis. Demographic, clinical, and genetic information was collected on Canadian MHS patients who presented with rhabdomyolysis. In addition, we performed a systematic review of the literature published during 1995-2016 on genetic screening of the RYR1 and CACNA1S genes in patients with ER. Retrospective data on Canadian MHS patients with ER showed that ten out of 17 patients carried RYR1 or CACNA1S variants that were either known MH-causative mutations or potentially pathogenic variants. The systematic review revealed 39 different rare RYR1 variants, including 13 MH-causative/associated mutations and five rare potentially deleterious CACNA1S variants in 78% of patients with ER. Findings from the Canadian patient cohort and the systematic review all signal a potential association between MH susceptibility and ER. The presence of MH-causative mutations and putative deleterious RYR1 variants in ER patients without a history of adverse anesthetic reactions suggests their possible increased risk for MH.

2016-10-01

The aims of this paper were to review our experience with necrotizing fasciitis at Middlemore Hospital and to define the trends in incidence, inpatient mortality and microbiological profile. A computerized search of the electronic medical records was undertaken to identify adult patients with a diagnosis of necrotizing fasciitis between January 2000 and December 2010. A retrospective review of the clinical records was performed. Of the 138 patients with necrotizing fasciitis identified, 129 had their diagnosis confirmed at operation. The mortality at 30 days was 20.3% (95% confidence interval (CI) 13.9%-28.0%). There was a significant reduction in hospital mortality in each successive year of the study period with an odds ratio of 0.84 (95% CI 0.71-0.98, P = 0.03). A pattern of increasing incidence was noted until February 2004 (95% CI September 2002-July 2005). This was followed by a significant decrease in incidence. The empirical antibiotic regime of clindamycin, gentamicin and penicillin provides satisfactory cover against 95% of the causative pathogens. This represents the largest single-centre published case series in New Zealand. Despite concerns of increasing incidence and mortality associated with necrotizing fasciitis in New Zealand, the experience in South Auckland shows a decrease in incidence of necrotizing fasciitis since 2004 and a statistically significant decreasing trend in hospital mortality. © 2015 Royal Australasian College of Surgeons.

The giant Pacific octopus (Enteroctopus dofleini) is a popular exhibit species in public display aquaria, but information on health and disease is limited. This retrospective review evaluates time in collection and describes antemortem clinical signs and pathology of giant Pacific octopuses in an aquarium setting. Between March 2004 and December 2013, there were 19 mortalities: eight males, 10 females, and one individual whose sex was not recorded. Average time spent in collection for all octopuses was 375 ± 173 days (males 351 ± 148 days, females 410 ± 196 days). Ten (52.6%) of the octopuses were sexually mature at the time of death, six (31.6%) were not sexually mature, and reproductive status could not be determined in three octopuses (15.8%). Minimal changes were noted on gross necropsy but branchitis was histologically evident in 14 octopuses, often in conjunction with amoeboid or flagellate parasites. Senescence, parasitism, and husbandry were all important contributors to mortality and should be considered when caring for captive octopuses.

The Joint Task Force on Practice Parameters for Allergy and Immunology recommends that patients with a history of a systemic reaction to an insect sting be educated on ways to avoid insect stings, carry injectable epinephrine for emergency self-treatment, undergo specific IgE testing for stinging insect sensitivity, and be considered for immunotherapy. To review frontline providers' documented care and recommendations for imported fire ant and flying insect hypersensitivity reactions. A retrospective medical record review was performed of emergency department and primary care clinic visits between November 1, 1999, and November 30, 2004. Using International Classification of Diseases, Ninth Revision, codes, medical records were selected for review to identify patients with potential insect hypersensitivity. A total of 769 medical records from patients who experienced an insect sting were reviewed. Of 120 patients with a systemic reaction, 66 (55.0%) received a prescription for injectable epinephrine, and 14 (11.7%) were given information regarding avoidance of the offending insect. Forty-seven patients with systemic reactions (39.2%) were referred to an allergist. Of 28 patients who kept their appointments and underwent skin testing, 3 had negative results and 25 (89%) had positive results and were advised to start immunotherapy. Adherence to the stinging insect hypersensitivity practice parameter recommendations is poor. Many patients who have experienced a systemic reaction after an insect sting and have sought medical care are not afforded an opportunity for potentially lifesaving therapy.

2017-04-01

The aim of this study was to review and describe the use of Prothrombinex by a physician-led retrieval service based remote from a hospital blood bank. This is a retrospective observational study. Patients to whom Prothrombinex was administered by the retrieval team were identified from the retrieval service patient database. The paper case cards of the identified patients were then manually reviewed and the data matched to patients in the state-wide electronic laboratory record. Between 1 January 2010 and 30 November 2013 38 cases were identified. For 28 the indication was warfarinisation associated with life-threatening bleeding (most commonly intracranial or gastrointestinal tract). In the remaining 10 cases, Prothrombinex was used to treat coagulopathy associated with liver disease or massive haemorrhage. The median time saved by the retrieval team administering PTX-VF, rather than waiting to the receiving centre, was 120 min (interquartile range: 85-195 min). The median dose of PTX-VF administered was 23.25 IU/kg (interquartile range: 20-33 IU/kg). Paired international normalised ratios (INRs) were available for 33 of the 38 patients. In the warfarin group, all patients had an improvement in their INR and 21 of 25 had correction of their INR. In the non-warfarin group, the effect on INR was more variable. Prothrombinex is a clinically useful product that can be relatively easily stored and used by retrieval services, even if they are based in isolation from a hospital blood bank. More research is required to look at the utility of Prothrombinex for non-warfarin-related bleeding in the pre-hospital and retrieval environment. © 2016 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Comparing the Medicaid Retrospective Drug Utilization Review Program Cost-Savings Methods Used by State Agencies.

Science.gov (United States)

Prada, Sergio I

2017-12-01

The Medicaid Drug Utilization Review (DUR) program is a 2-phase process conducted by Medicaid state agencies. The first phase is a prospective DUR and involves electronically monitoring prescription drug claims to identify prescription-related problems, such as therapeutic duplication, contraindications, incorrect dosage, or duration of treatment. The second phase is a retrospective DUR and involves ongoing and periodic examinations of claims data to identify patterns of fraud, abuse, underutilization, drug-drug interaction, or medically unnecessary care, implementing corrective actions when needed. The Centers for Medicare & Medicaid Services requires each state to measure prescription drug cost-savings generated from its DUR programs on an annual basis, but it provides no guidance or unified methodology for doing so. To describe and synthesize the methodologies used by states to measure cost-savings using their Medicaid retrospective DUR program in federal fiscal years 2014 and 2015. For each state, the cost-savings methodologies included in the Medicaid DUR 2014 and 2015 reports were downloaded from Medicaid's website. The reports were then reviewed and synthesized. Methods described by the states were classified according to research designs often described in evaluation textbooks. In 2014, the most often used prescription drugs cost-savings estimation methodology for the Medicaid retrospective DUR program was a simple pre-post intervention method, without a comparison group (ie, 12 states). In 2015, the most common methodology used was a pre-post intervention method, with a comparison group (ie, 14 states). Comparisons of savings attributed to the program among states are still unreliable, because of a lack of a common methodology available for measuring cost-savings. There is great variation among states in the methods used to measure prescription drug utilization cost-savings. This analysis suggests that there is still room for improvement in terms of

The objective of this study was to review the clinical outcome after treatment of distal posterior cerebral artery (PCA) aneurysms via endovascular approach. Eleven patients with 11 distal PCA aneurysms who were treated via endovascular approach in Inje University Busan Paik Hospital and Kosin University Gospel Hospital from December 2002 to December 2013 were retrospectively reviewed. Among the 11 patients, there were 3 males (27.3%) and 8 females (72.7%). The mean age was 56.6 years (range 44 -72 years) and the mean aneurysm size was 8.45 mm (3 - 30 mm). Four (36.4%) aneurysms were located in the P2 segment, 6 (54.5%) in the P3 segment and 1 (9.1%) in the P1/2 junction. Seven (63.6%) aneurysms were treated with preservation of the parent artery; and the remaining 4 (36.4%) aneurysms were treated with parent artery occlusion. After treatment, the overall complication rate was 27% with the morbidity rate of 9.1% and the mortality rate of 18%. Endovascular treatment of distal PCA aneurysm might be used to minimize neurologic deficit, considering the diverse and rich collaterals of posterior cerebral artery

Gut flora are important immunomodulators that may be disrupted in individuals with atopic conditions. Probiotic bacteria have been suggested as therapeutic modalities to mitigate or prevent food allergic manifestations. We wished to investigate whether perinatal factors known to disrupt gut flora increase the risk of IgE-mediated food allergies. Birth records obtained from 192 healthy children and 99 children diagnosed with food allergies were reviewed retrospectively. Data pertaining to delivery method, perinatal antibiotic exposure, neonatal nursery environment, and maternal variables were recorded. Logistic regression analysis was used to assess the association between variables of interest and subsequent food allergy diagnosis. Retrospective investigation did not find perinatal antibiotics, NICU admission, or cesarean section to be associated with increased risk of food allergy diagnosis. However, associations between food allergy diagnosis and male gender (66 vs. 33; p=0.02) were apparent in this cohort. Additionally, increasing maternal age at delivery was significantly associated with food allergy diagnosis during childhood (OR, 1.05; 95% CI, 1.017 to 1.105; p=0.005). Gut flora are potent immunomodulators, but their overall contribution to immune maturation remains to be elucidated. Additional understanding of the interplay between immunologic, genetic, and environmental factors underlying food allergy development need to be clarified before probiotic therapeutic interventions can routinely be recommended for prevention or mitigation of food allergies. Such interventions may be well-suited in male infants and in infants born to older mothers.

Patients with congenital hypopituitarism might have the classic triad of pituitary stalk interruption syndrome, which consists of: (1) an interrupted or thin pituitary stalk, (2) an absent or ectopic posterior pituitary (EPP), and (3) anterior pituitary hypoplasia or aplasia. To examine the relationship between pituitary anatomy and the degree of hormonal dysfunction. This study involved a retrospective review of MRI findings in all children diagnosed with congenital growth hormone deficiency from 1988 to 2010 at a tertiary-level pediatric hospital. Of the 52 MRIs reviewed in 52 children, 26 children had normal pituitary anatomy and 26 had one or more elements of the classic triad. Fourteen of fifteen children with multiple pituitary hormone deficiencies had structural anomalies on MRI. Twelve of 37 children with isolated growth hormone deficiency had an abnormal MRI. Children with multiple pituitary hormone deficiencies were more likely to have the classic triad than children with isolated growth hormone deficiency. A normal MRI was the most common finding in children with isolated growth hormone deficiency. (orig.)

Developmental milestone markers for fine motor and self-care skills among children with Down syndrome (DS) are either minimal, anecdotal or out-of date. Our goal was to produce normative expectations for the development of fine motor and self-care milestones specific to children with DS. A cross-sectional retrospective chart review was completed on 274 children with DS seen at a specialty clinic that ranged in age from 4 months to 18 years. Specific skills were assessed at occupational therapy assessments as either present or absent, including fine motor, handwriting, scissor usage, self-feeding and clothing management. Fine motor milestones describing when 10-30% ('early achievers') and 75-95% ('representative achievement') of children with DS had mastered each skill were developed based upon descriptive review. As the fine motor and self-care skills advanced in complexity, the range of ages for documented skill acquisition was observed to increase. Age ranges for the mastery of fine motor developmental milestones for early and representative achievement were developed based upon descriptive analysis of cross-sectional retrospective clinical chart reviews. That the age range for mastering fine motor and self-care skills broadens as children with DS get older is in agreement with what is identified in the DS behavioural phenotype with regard to variable motor skills overall. These fine motor and self-care developmental milestone markers contribute to the field by informing parents, caregivers and healthcare providers of potential fine motor and self-care outcomes and describing normative development for children with DS. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Purpose: To perform a systematic review of the radiation dose and diagnostic accuracy of prospective versus retrospective ECG-gated multislice CT coronary angiography. Materials and methods: A search of Pubmed/Medline and Sciencedirect databases for English literature was performed to identify studies comparing prospective and retrospective ECG-gated multislice CT angiography in the diagnosis of coronary artery disease. Effective dose, dose length product, image quality and diagnostic value were compared between two groups of studies. Results: 22 studies were included for analysis. The mean effective dose of prospective ECG-gated scans was 4.5 mSv (95% CI: 3.6, 5.3 mSv), which is significantly lower than that of retrospective scans, which is 13.8 mSv (95% CI: 11.5, 16.0 mSv) (p < 0.001). The mean dose length product was 225 mGy cm (95% CI: 188, 262 mGy cm) and 822 mGy cm (95% CI: 630, 1013 mGy cm) for the prospective and retrospective ECG-gated scans, respectively, indicating a statistically significant difference between these two protocols (p < 0.0001). The mean sensitivity and specificity of multislice CT angiography in the diagnosis of coronary artery disease was 97.7% (95% CI: 93.7%, 100%) and 92.1% (95% CI: 87.2%, 97%) for prospective ECG-gated scans; 95.2% (95% CI: 91%, 99.5%) and 94.4% (95% CI: 88.5%, 100%) for retrospective ECG-gated scans, respectively, with no significant difference for sensitivity but significant difference for specificity (p = 0.047). Conclusion: Multislice CT coronary angiography with prospective ECG-gating leads to a significant reduction of radiation dose when compared to that of retrospective ECG-gating, while offering comparable image quality and diagnostic value.

To consolidate and assess information on counterfeit medicines subject to pharmaceutical alerts issued by the Peruvian Medicines Regulatory Authority over 18 years (1997-2014) of health monitoring and enforcement. A retrospective review of drug alerts. A search of the website of the General Directorate of Medicines, Supplies and Drugs (DIGEMID) of the Ministry of Health of Peru for drug alerts issued between 1997 and 2014. Drug alerts related to counterfeit medicines. A total of 669 DIGEMID alerts were issued during the study period, 354 (52.91%) of which cover 1738 cases of counterfeit medicines (many alerts deal with several cases at a time). 1010 cases (58.11%) involved pharmaceutical establishments and 349 (20.08%) involved non-pharmaceutical commercial outlets. In 126 cases (7.25%), counterfeit medicines were seized in an unauthorised trade (without any marketing authorisation); in 253 cases (14.56%) the type of establishment or business associated with the seized product was not identified. Counterfeit medicines are a serious public health problem in Peru. A review of the data cannot determine whether counterfeit medicines in Peru increased during the study period, or if monitoring by different government health agencies highlighted the magnitude of the problem by providing more evidence. The problem is clearly structural, since the majority of cases (58.11% of the total) were detected in legitimate supply chains. Most counterfeit medicines involve staple pharmaceutical products and common dosage forms. Considerable work remains to be done to control the serious problem of counterfeit medicines in Peru.

To better understand lightning deaths, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 1977 and 2009 to update and assess current risk factors. Information on demographics, circumstances, autopsy, and death certificates were collected and analyzed. Fifty-four decedents were identified, ages 2-71 years old (mean 34 years old), 42 males and 12 females. Common racial/ethnic groups were non-Hispanic Whites and American Indians (together comprising 72% of all cases). Physical findings were often related to the heat carried by the electrical current including clothing alterations (29.6%) and burning of skin (53.7%). Most deaths occurred on weekend afternoons in summer months, associated with recreational activities or agricultural work, and rural locations (77.8%). Utilizing the demographic information, clustered events, and associated outdoor activities will assist in creating public awareness and provide a framework to support targeted warnings in an attempt to prevent future deaths. © 2014 American Academy of Forensic Sciences.

Introduction: In 1999, the American Board of Radiology (ABR) implemented an innovative training program track in diagnostic radiology (DR) and radiation oncology (RO) designed to stimulate development of a cadre of future academic researchers and educators in the 2 disciplines. The program was designated the Holman Research Pathway (HRP). An in-depth retrospective review of initial certification examination performance, post-training career choices, and academic productivity has not been written. This report represents a 10-year retrospective review of post-training performance of a cohort of trainees who have had sufficient time to complete their training and initial certification process and to enter practice. Methods and Materials: All pertinent proceedings of the ABR and Accreditation Council for Graduate Medical Education (ACGME) Residency Review Committees for DR and RO between 1997 and May 2011 were reviewed. Thirty-four HRP candidates who fulfilled the established evaluation criteria were identified, and their ABR data files were analyzed regarding performance on the qualifying and certifying examinations. All candidates were contacted directly to obtain a current curriculum vitae. Results: Twenty candidates in RO and 14 candidates in DR were identifiable for review. All candidates attained initial certification. At the time of analysis, 23 of 33 (66.6%) candidates were employed in full-time academic practice (1 DR candidate remained in a fellowship and was not evaluated regarding employment status). Fifteen of 20 (75%) RO candidates were in faculty positions compared with 7 of 13 (53.8%) DR trainees. Additional academic productivity metrics are reported. Conclusions: A high percentage of HRP trainees remained in academic practice and demonstrated significant academic productivity as measured by manuscript authorship and research support. Additional time and observation will be needed to determine whether these findings will be sustained by past, current

Post-traumatic stress disorder (PTSD) is a well-established psychological disorder after severe traumatic injury but remains poorly recognized. Recent changes in the "Resources for Optimal Care of the Injured Trauma Patient 2014" stress the need for comprehensive screening and referral for PTSD and depression after injury. Our purpose was to review the current PTSD literature and perform a retrospective chart review to evaluate screening at our institution. We hypothesized a lack of documentation and thus referral of these patients to mental health professionals. We performed a literature review of 43 publications of risk factors for PTSD in the civilian adult population followed by a retrospective review. Records were analyzed for basic demographics, risk factors found in the literature, and referrals to mental health providers. Risk factors included amputation, dissociative symptoms, female gender, history of mental health disorder, and peri-traumatic emotionality. Traumatic amputation status and gender were recorded in all patients. History of mental health disorder was present in 11.5 per cent patients, absent in 80.75 per cent, and not recorded in 7.75 per cent with an overall documentation of 91.75 per cent. Dissociative symptoms and peri-traumatic emotionality were recorded in 0.5 per cent and 1.0 per cent of patients, respectively. Only 13 patients of 400 (3.25%) were referred to mental health professionals. Despite extensive evidence and literature supporting risk factors for the development of PTSD, identification and treatment at our level 1 trauma center is lacking. There is a need for consistent screening among trauma centers to identify PTSD risk factors and protocols for risk reduction and referrals for patients at risk.

Full Text Available Mallik Angalakuditi1, Joseph Gomes21Georgia State University, Atlanta, GA, USA; 2Baxter Health Care, Deerfield, IL, USAObjectives: To evaluate the impact of retrospective drug utilization review (RDUR, pharmacist’s interventions on physician prescribing, and the level of spillover effect on future prescriptions following the intervention.Methods: A retrospective case–control study was conducted at a pharmacy benefits management company using the available prescription data from April 2004 to August 2005. RDUR conflicts evaluated and intervened by a clinical pharmacist served as a case group, whereas conflicts that were not evaluated and intervened by a clinical pharmacist served as a control group.Results: A total of 40,284 conflicts in cases and 13,044 in controls were identified. For cases, 32,780 interventions were considered nonrepetitive, and 529 were repetitive. There were 22,870 physicians in cases that received intervention letters and 2348 physicians in the control group that would have received intervention letters during the study period. Each physician received on average 1.4 interventions for cases vs 3.0 for controls. Among the case physicians who were intervened during the study period, 2.2% (505 were involved in a repeated intervention vs 18.2% (428 in controls (P < 0.001, which is an eight-fold difference. The most common conflict intervened on in cases was therapeutic appropriateness (8277, 25.3%, and for controls it was drug–drug interactions (1796, 25.4%. The overall interventional spillover effect in cases was 98.4% vs 89.4% in controls (P = 0.01.Conclusion: RDUR is an effective interventional program which results in decreased numbers of interventions per physician and provides a significant impact on future prescribing habits.Keywords: pharmacy management, spillover effect, RDUR, DUR

Full Text Available Background. Pectoralis major tendon ruptures have been reported in the literature as occupational injuries, accidental injuries, and sporting activities. Few cases have been reported with respect to rodeo activities. Purpose. To describe a series of PM tendon ruptures in professional steer wrestlers. Study Design. Case series, level of evidence, 4. Methods. A retrospective analysis of PM ruptures in a steer wrestling cohort was performed. Injury data between 1992 and 2008 were reviewed using medical records from the University of Calgary Sport Medicine Center. Results. Nine cases of pectoralis major ruptures in professional steer wrestlers were identified. Injuries occurred during the throwing phase of the steer or while breaking a fall. All athletes reported unexpected or abnormal behavior of the steer that contributed to the mechanism of injury. Seven cases were surgically repaired, while two cases opted for nonsurgical intervention. Eight cases reported successful return to competition following the injury. Conclusion. Steer wrestlers represent a unique cohort of PM rupture case studies. Steer wrestling is a demanding sport that involves throwing maneuvers that may predispose the muscle to rupture. All cases demonstrated good functional outcomes regardless of surgical or non-surgical treatment.

Full Text Available Background/Aims With the notable exceptions of dementia, stroke, and motor neuron disease, relatively little is known about the safety and utility of percutaneous endoscopic gastrostomy (PEG tube insertion in patients with neurodegenerative disease. We aimed to determine the safety and utility of PEG feeding in the context of neurodegenerative disease and to complete a literature review in order to identify whether particular factors need to be considered to improve safety and outcome. Methods A retrospective case note review of patients referred for PEG insertion by neurologists in a single neuroscience center was conducted according to a pre-determined set of standards. For the literature review, we identified references from searches of PubMed, mainly with the search items “percutaneous endoscopic gastrostomy” and “neurology” or “neurodegenerative disease.” Results Short-term mortality and morbidity associated with PEG in patients with neurological disease were significant. Age greater than 75 years was associated with poor outcome, and a trend toward adverse outcome was observed in patients with low serum albumin. Conclusions This study highlights the relatively high risk of PEG in patients with neurodegenerative disease. We present points for consideration to improve outcome in this particularly vulnerable group of patients.

2013-01-01

Pelvic floor physical therapy is used in the treatment of sexual pain disorders; however, women with lifelong vaginismus have not yet been included in treatment studies or have not been differentiated from women with acquired vaginismus and/or dyspareunia. This retrospective chart review and interview study was intended to obtain initial information on physical therapy interventions, course, and outcome in women who have never been able to experience vaginal intercourse. The files of 53 women, consecutively treated at one physical therapy clinic, were included in the chart review; 13 of these women volunteered to be interviewed. The chart review revealed significant pelvic floor pathology and an average treatment course of 29 sessions. Internal manual techniques were found to be most effective, followed by patient education, dilatation exercises, and home exercises. Although participants were very satisfied with the physical therapy, some symptoms, such as pain, anxiety/fear, and pelvic floor tension remained and scores on the Female Sexual Distress Scale and Female Sexual Function Index indicated clinical levels of sexual distress and impaired sexual function after treatment. Although there appears to be no linear relation between symptom reduction and healthy sexual function, this initial information suggests that physical therapy may be a promising treatment option for some women with lifelong vaginismus and merits further evaluation.

Richards, Carly R; Clark, Margaret E; Sutherland, Ronald S; Woo, Russell K

2017-05-01

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.

Full Text Available The objective of this paper was (1 to assess compliance with the National Veterans Affairs Guidelines for the use of troglitazone and rosiglitazone and (2 to develop and implement a conversion protocol that allows effective management of patients receiving troglitazone. A retrospective chart review was conducted to assess adherence to guidelines for all patients receiving troglitazone and rosiglitazone at the medical center. Appropriateness of therapy through indication evaluation, safety through alanine aminotransferase (ALT monitoring compliance, and efficacy through hemoglobin A1c (HbA1c changes were used to assess adherence. According to National Veterans Affairs (VA Guidelines, 68% of troglitazone and 63% of rosiglitazone patients had an appropriate indication for the use of these agents. Baseline ALT levels were obtained in 40% of troglitazone and 71% of rosiglitazone patients. Full compliance with continual ALT monitoring was seen in 6 and 54% of patients, respectively. Goal HbA1c was achieved in 57 and 29% of patients, respectively. Of the 33 patients receiving troglitazone, 19 were converted to rosiglitazone therapy; 11 were maintained on current regimens without troglitazone, and 3 were lost to follow up. Adherence to guidelines needs to be reinforced, in particular, compliance with ALT monitoring. However, there were no reported cases of hepatotoxicity in the patients reviewed. Many patients did not achieve a HbA1c

1996-08-09

A retrospective review of patients being treated by percutaneous endoscopic gastrostomy (PEG) at Auckland Hospital from 1993-4 was undertaken in order to determine patient characteristics, clinical outcome and to compare these results with published series. The case notes of all patients having PEGs performed in the Auckland Hospital gastroenterology unit during the defined period were reviewed. Demographic details, indications, morbidity and mortality data were obtained. Data were supplemented with information obtained from the general practitioner. Fifty procedures (18 in 1993, 32 in 1994) were performed on 41 patients (29 male 12 female), with a mean age of 61 years. Neurological disorders represented the most common clinical indication (25) followed by head and neck malignancy (9). Three patients (7) died within 30 days of the procedure and 13 (32) had early complications (less than 30 days) with four (10) having late complications. Significant pain requiring narcotics occurred in 18. Results were in general comparable to published series apart from a higher early complication rate (32% vs 16%). Pain may be significant post procedure and should be anticipated. The increasing use of this procedure in our hospital reflects its acceptability to patients, relatives and staff as a means of providing nutritional support to the patient with disorders of swallowing.

To assess whether reports from reviewers recommended by authors show a bias in quality and recommendation for editorial decision, compared with reviewers suggested by other parties, and whether reviewer reports for journals operating on open or single-blind peer review models differ with regard to report quality and reviewer recommendations. Retrospective analysis of the quality of reviewer reports using an established Review Quality Instrument, and analysis of reviewer recommendations and author satisfaction surveys. BioMed Central biology and medical journals. BMC Infectious Diseases and BMC Microbiology are similar in size, rejection rates, impact factors and editorial processes, but the former uses open peer review while the latter uses single-blind peer review. The Journal of Inflammation has operated under both peer review models. Two hundred reviewer reports submitted to BMC Infectious Diseases, 200 reviewer reports submitted to BMC Microbiology and 400 reviewer reports submitted to the Journal of Inflammation. For each journal, author-suggested reviewers provided reports of comparable quality to non-author-suggested reviewers, but were significantly more likely to recommend acceptance, irrespective of the peer review model (previewer reports measured by the Review Quality Instrument was 5% higher than for BMC Microbiology (p=0.042). For the Journal of Inflammation, the quality of reports was the same irrespective of the peer review model used. Reviewers suggested by authors provide reports of comparable quality to non-author-suggested reviewers, but are significantly more likely to recommend acceptance. Open peer review reports for BMC Infectious Diseases were of higher quality than single-blind reports for BMC Microbiology. There was no difference in quality of peer review in the Journal of Inflammation under open peer review compared with single blind. Published by the BMJ Publishing Group Limited.

Paresthesia is an adverse event that may be associated with the administration of local anesthetics in dentistry. The purpose of this retrospective study was to analyze cases of paresthesia associated with local anesthetic injection that were voluntarily reported to Ontario"s Professional Liability Program (PLP) from 1999 to 2008 inclusive, to see if the findings were consistent with those from 1973 to 1998 from this same source. All cases of nonsurgical paresthesia reported from 1999 to 2008 were reviewed; cases involving surgical procedures were excluded. Variables examined included patient age and gender, type and volume of local anesthetic, anatomic site of nerve injury, affected side and pain on injection or any other symptoms. During the study period, 182 PLP reports of paresthesia following nonsurgical procedures were made; all but 2 were associated with mandibular block injection. There was no significant gender predilection, but the lingual nerve was affected more than twice as frequently as the inferior alveolar nerve. During 2006-2008 alone, 64 cases of nonsurgical paresthesia were reported to PLP, a reported incidence of 1 in 609,000 injections. For the 2 local anesthetic drugs available in dental cartridges as 4% solutions, i.e., articaine and prilocaine, the frequencies of reporting of paresthesia were significantly greater than expected (chi2, exact binomial distribution; p paresthesia.

Knowledge of epidemiology is important for recognition of cardiovascular malformations. Review the incidence of congenital heart defects in dogs in Italy and assess breed and sex predispositions. Nine hundred and seventy-six dogs diagnosed with congenital heart disease (CHD) of 4,480 dogs presented to Clinica Veterinaria Gran Sasso for cardiovascular examination from 1997 to 2010. A retrospective analysis of medical records regarding signalment, history, clinical examination, radiography, electrocardiography, echocardiography, angiography, and postmortem examination was performed. Breed and sex predisposition were assessed with the odds ratio test. CHD was observed in 21.7% of cases. A total of 1,132 defects were observed with single defects in 832 cases (85%), 2 concurrent defects in 132 cases (14%), and 3 concurrent defects in 12 cases (1%). The most common defects were pulmonic stenosis (PS; 32.1%), subaortic stenosis (SAS; 21.3%), and patent ductus arteriosus (20.9%), followed by ventricular septal defect (VSD; 7.5%), valvular aortic stenosis (AS; 5.7%), and tricuspid dysplasia (3.1%). SAS, PS, and VSD frequently were associated with other defects. Several breed and sex predispositions were identified. The results of this study are in accordance with previous studies, with slight differences. The breed and sex predilections identified may be of value for the diagnosis and screening of CHD in dogs. Additionally, the relatively high percentage of concurrent heart defects emphasizes the importance of accurate and complete examinations for identification. Because these data are from a cardiology referral center, a bias may exist. Copyright © 2011 by the American College of Veterinary Internal Medicine.

Background and Purpose: Radiofrequency ablation (RFA) is associated with low neural morbidity compared with surgery, which commonly causes debilitating long-term pain. The purpose was to review the thoracic neural anatomy relevant to percutaneous RFA and to retrospectively review symptomatic nerve injury after lung RFA at our institution. Materials and Methods: We retrospectively examined all symptomatic nerve injuries occurring after computed tomography (CT)-guided RFA treatment of lung tumors for 462 patients/509 procedures/708 lesions treated at our large tertiary referral centre during 10 years. Results: Eight patients experienced neurological complications after heating during the RFA procedure. These complications occurred in the phrenic (n = 1), brachial (n = 3), left recurrent (n = 1), and intercostal nerves (n = 2) and the stellate ganglion (n = 1). Three were grade 2, four grade 3 and one grade 4 injuries (CTCAE v3). Conclusion: Although rare, neurological complications can occur after RFA, and they can occasionally be severe. To prevent these complications, it is important for the interventional radiologist to be aware of the anatomy of nervous structures and to attempt to identify nerves on CT scans during the RFA procedure. Creating a pneumothorax can be useful to avoid nerve damage and related clinical complications.

Cerebral mycotic aneurysms are a rare and deadly type of aneurysm that have no definitive treatment guidelines. Our purpose was to retrospectively review known or suspected cases of CMA in order to identify patient populations that may be associated with higher morbidity and mortality. We hope that the identification of patients with these risk factors will lead to early stratification upon presentation, and more urgent treatment of their CMAs. We also hoped to identify any benefit or complication that was specific to either the endovascular or neurosurgical repair of CMAs. A retrospective multi-institutional study was performed examining cases of CMA during a 15-year period. Patients were considered strongly immunocompromised if there were long-term severely immunocompromised states: AIDS, chemotherapy, or steroid immunosuppression. Patients were excluded if angiographic findings suggested an alternative diagnosis or if an infectious etiology was unknown. Antibiotics were considered "noninvasive treatment." Endovascular and neurosurgical repair were considered "invasive treatment." Data were recorded by reviewing electronic medical records and imaging reports. Twenty-six patients with 40 CMAs were included. Three patients were considered strongly immunocompromised and presented with 4 CMAs, which demonstrated larger average size and more rapid growth; 3 of these patients' aneurysms were treated invasively in the acute period, with the one that was not ruptured causing death. Technical success (aneurysm occlusion without rupture or recanalization) and clinical success (no neurologic complication attributable to the intervention) were obtained equally endovascularly and neurosurgically. Clipping was aborted in favor of coiling for 1 patient. Anticoagulation needed reversal before 2 patients underwent craniotomy for clipping after valve replacement. For CMAs treated with antibiotics alone with angiographic follow-up (n=11), initial aneurysm size was unrelated to

2016-01-01

The efficacy of the transversus abdominis plane (TAP) block appears to vary considerably, depending on the surgical procedure and block technique. This study aims to add to the existing literature and provide a more clear understanding of the TAP blocks role as a postoperative analgesic technique, specifically in renal allotransplant recipients. A retrospective chart review was conducted by querying the intraoperative electronic medical record system of a 1200-bed tertiary academic hospital over a 5 months period, and reviewing anesthetic techniques, as well as postoperative morphine equivalent consumption. Fifty renal allotransplant recipients were identified, 13 of whom received TAP blocks while 37 received no regional analgesic technique. All blocks were performed under ultrasound guidance, with 20 mL of 0.25% bupivacaine injected in the transversus abdominis fascial plane under direct visualization. The primary outcome was postoperative morphine equivalent consumption. Morphine consumption was compared with the two-tailed Mann-Whitney U -test. Continuous variables of patient baseline characteristics were analyzed with unpaired t -test and categorical variables with Fischer Exact Test. A P consumption was found in the group that received the TAP block at 6 h (2.46 mg vs. 7.27 mg, P = 0.0010), 12 h (3.88 mg vs. 10.20 mg, P = 0.0005), 24 h (6.96 mg vs. 14.75 mg, P = 0.0013), and 48 h (11 mg vs. 20.13 mg, P = 0.0092). The TAP block is a beneficial postoperative analgesic, opiate-sparing technique in renal allotransplant recipients.

BACKGROUND: A subset of critically ill patients have end-of-life (EOL) goals that are unclear. Rapid response teams (RRTs) may aid in the identification of these patients and the delivery of their EOL care. OBJECTIVES: To characterize the impact of RRT discussion on EOL care, and to examine how a preprinted order (PPO) set for EOL care influenced EOL discussions and outcomes. METHODS: A single-centre retrospective chart review of all RRT calls (January 2009 to December 2010) was performed. The effect of RRT EOL discussions and the effect of a hospital-wide PPO set on EOL care was examined. Charts were from the Ontario Ministry of Health and Long-Term Care Critical Care Information Systemic database, and were interrogated by two reviewers. RESULTS: In patients whose EOL status changed following RRT EOL discussion, there were fewer intensive care unit (ICU) transfers (8.4% versus 17%; PEOL status following the introduction of an EOL PPO, from 20% (before) to 31% (after) (PEOL status following RRT-led EOL discussion was associated with reduced ICU transfers and enhanced access to palliative care services. Further study is required to identify and deconstruct barriers impairing timely and appropriate EOL discussions. PMID:25299222

Full Text Available Introduction and objectiveActive surveillance (AS has become an accepted alternative for patients with low risk prostate cancer. The purpose of AS is to defer definitive therapy in these patients to avoid treatment-related complications. Our aim was to determine the pathological features of the surgical specimen from potential AS candidates that underwent radical prostatectomy (RP.Materials and MethodsWe retrospectively reviewed a group of patients submitted to RP who met criteria for AS: Gleason score (GS ≤ 3+3 = 6, PSA ≤ 10ng/mL, T1c - T2a, 6 in the RPS (GS 7 n = 49; GS 8 n = 3. Extracapsular extension, seminal vesicle and lymph node involvement was found in 6.1%, 3.1% and 1.2% of the specimens, respectively.ConclusionIn this study a significant proportion of potential candidates for AS showed features of aggressive and/or high-risk tumors in the RPS. Therefore, before considering a patient for an AS protocol, a proper and strict selection must be performed, and informed consent is crucial for these patients.

PurposeThe OptEase vena cave filter (Cordis, Piscataway, NJ) is commercially available as a retrievable or permanent filter with short recommended indwelling time, presumably due to extensive contact of the filter side struts with the inferior vena cava wall and subsequent neointimal hyperplasia leading to incorporation. Our purpose was to evaluate OptEase filter retrievals with a long indwelling time period that required unconventional retrieval techniques.Materials and MethodsWe retrospectively reviewed patients who underwent OptEase filter retrieval with long undwelling times requiring additional maneuvers for retrieval. Techniques used included rigid endobronchial forceps dissection and wire-through-loop snare. Each patient underwent postretrieval venogram to evaluate for possible complications. In addition, patients had clinical follow-up 2 weeks after the retrieval procedure.ResultsThere were three patients (2 women, 1 man; average age 64 years) who underwent OptEase filter retrieval. The mean indwelling time was 6.4 months. The indwelling filters were successfully retrieved. There were no complications. Postprocedural follow-up showed no clinical pathology.ConclusionUnconventional techniques aided in the retrieval of OptEase filters with long indwelling times.

Bolek, Jeffrey E

2006-09-01

We completed a retrospective review of the effectiveness of multi-site, performance-contingent reward programming on functional change in motor performance of 16 treatment resistant children. Patients were previously treated in physical or occupational therapy for head control, standing balance training, sitting and upper extremity use (brachial plexus injury). They then participated in a program that utilized multiple surface electromyography sites the use of which was rewarded with videos for performing the correct constellation of recruitment pattern (e.g., contracting some muscles while relaxing others). Onset of reward was calibrated for each patient and transfer of skill to outside the clinic was encouraged by linking a verbal cue to the correct motor plan. Fourteen of the 16 patients improved. The implications of the use of this technique in the treatment of motor dysfunction is discussed.

Readmissions within 30-days of hospital discharge are a problem. The aim was to determine if the Better Outcomes for Older Adults through Safe Transitions (BOOST) risk assessment tool was applicable within the UK. Patients over 65 readmitted were identified retrospectively via a casenote review. BOOST assessment was applied with 1 point for each risk factor. 324 patients were readmitted (mean age 77 years) with a median of 7 days between discharge and readmission. The median BOOST score was 3 (IQR 2-4) with polypharmacy evident in 88% and prior hospitalisation in 70%. The tool correctly predicted 90% of readmissions using two or more risk factors and 99.1% if one risk factor was included. The BOOST assessment tool appears appropriate in predicting readmissions however further analysis is required to determine its precision.

Berk, David R

2012-01-01

Terra firma-forme dermatosis is an idiopathic condition characterized by acquired, dirtlike plaques despite normal hygiene. A diagnosis can be reached by removing lesions with gentle alcohol swabbing. Although Terra firma-forme dermatosis was first described more than 20 years ago and is thought to be not uncommon in clinical practice, it has never been systematically studied. There are few publications about this condition, including no case series of more than six patients. In particular, little is known about the incidence, peak age groups, and most common locations of Terra firma-forme dermatosis. A retrospective review was conducted to identify cases of Terra firma-forme dermatosis in a single-provider practice consisting of 55% pediatric and 45% adult patients. Thirty-one patients with Terra firma-forme dermatosis were identified, including 10 who presented with Terra firma-forme dermatosis as their primary concern. Only two patients were older than 17 years. The median duration of lesions was 4 months. The most common lesion locations were the neck, ankles, and face. Before presenting to the dermatology clinic, three patients had undergone endocrine evaluations, and four had been prescribed topical corticosteroids. Terra firma-forme dermatosis is relatively common and most often occurs in children on the neck or posterior malleolus. This series exemplifies the importance of recognizing Terra firma-forme dermatosis so as to provide rapid relief for patients and avoid unnecessary tests and treatments. © 2011 Wiley Periodicals, Inc.

Cervical cancer in young women presents a diagnostic challenge because gynaecological symptoms are common but underlying disease is rare. To explore the potential for using cytology as a diagnostic aid for cervical cancer in young women. Retrospective review of primary care records and cytology data from the national cervical screening database and national audit of cervical cancers. Four datasets of women aged 20-29 years in England were examined: primary care records and national screening data from an in-depth study of cervical cancers; cytology from the national audit of cervical cancers; whole-population cytology from the national screening database; and general-population primary care records from the Clinical Practice Research Datalink. The authors explored the sensitivity and positive predictive value (PPV) of symptomatic cytology (earliest cytology. Cytology has value beyond screening, and could be used as a diagnostic aid for earlier detection of cervical cancer in young women with gynaecological symptoms by ruling in urgent referral. © British Journal of General Practice 2016.

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.

Full Text Available Resuscitation plans (RP are an important clinical indicator relating to care at the end of life in paediatrics. A retrospective review of the medical records of children who had been referred to the Royal Children’s Hospital, Brisbane, Australia who died in the calendar year 2011 was performed. Of 62 records available, 40 patients (65% had a life limiting condition and 43 medical records (69% contained a documented RP. This study demonstrated that both the underlying condition (life-limiting or life-threatening and the setting of care (Pediatric Intensive Care Unit or home influenced the development of resuscitation plans. Patients referred to the paediatric palliative care (PPC service had a significantly longer time interval from documentation of a resuscitation plan to death and were more likely to die at home. All of the patients who died in the paediatric intensive care unit (PICU had a RP that was documented within the last 48 h of life. Most RPs were not easy to locate. Documentation of discussions related to resuscitation planning should accommodate patient and family centered care based on individual needs. With varied diagnoses and settings of care, it is important that there is inter-professional collaboration, particularly involving PICU and PPC services, in developing protocols of how to manage this difficult but inevitable clinical scenario.

To review the clinical, radiological, and laboratory presentations of patients with neoplastic meningitis. Patients with neoplastic meningitis were recruited by a retrospective search of cerebrospinal fluid (CSF) cytopathological report database of Siriraj Hospital between 1997 and 2006. Clinical information and CSF result of these patients were extracted from their medical records. Neuroimagings were reviewed by a neuroradiologist. The present study revealed 40 cases of neoplastic meningitis, which comprised of 17 cases with carcinomatous meningitis (CM) and 23 lymphoma/leukemia meningitis (LM) cases. In patients with CM, the majority (70%) had adenocarcinoma of lung or breast. Three of 17 cases with unknown primary tumor had carcinomatous meningitis as an initial presentation. In LM most of the cases (70%) were diagnosed with acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). The most common symptom among patients with CM and LM was headache follow by cranial nerve palsy. In CM cases, CSF cytology was positive in the first specimen in 15 cases (82.35%) and in 22 from 23 cases (95.7%) in LM cases. Overall CSF showed pleocytosis in 36 cases (90%), most of which were lymphocyte predominant. The most common findings from brain imagings were leptomeningeal enhancement and hydrocephalus. The common primary sites were lung and breast cancer in the CM group and ALL and NHL in the LM group. The common symptoms were headache and cranial nerve palsy. Routine CSF examination was abnormal in virtually all cases. Positive CSF cytology was a gold standard for a diagnosis of leptomeningeal metastasis. High index of suspicious and awareness were required to avoid miss diagnosis.

Prescribing error may result in adverse clinical outcomes leading to increased patient morbidity, mortality and increased economic burden. Many errors occur during transitional care as patients move between different stages and settings of care. To conduct a review of medication information and identify prescribing error among an adult population in an urban hospital. Retrospective review of medication information was conducted. Part 1: an audit of discharge prescriptions which assessed: legibility, compliance with legal requirements, therapeutic errors (strength, dose and frequency) and drug interactions. Part 2: A review of all sources of medication information (namely pre-admission medication list, drug Kardex, discharge prescription, discharge letter) for 15 inpatients to identify unintentional prescription discrepancies, defined as: "undocumented and/or unjustified medication alteration" throughout the hospital stay. Part 1: of the 5910 prescribed items; 53 (0.9%) were deemed illegible. Of the controlled drug prescriptions 11.1% (n = 167) met all the legal requirements. Therapeutic errors occurred in 41% of prescriptions (n = 479) More than 1 in 5 patients (21.9%) received a prescription containing a drug interaction. Part 2: 175 discrepancies were identified across all sources of medication information; of which 78 were deemed unintentional. Of these: 10.2% (n = 8) occurred at the point of admission, whereby 76.9% (n = 60) occurred at the point of discharge. The study identified the time of discharge as a point at which prescribing errors are likely to occur. This has implications for patient safety and provider work load in both primary and secondary care.

This is a descriptive analysis, of victims of Turkey's October 23, 2011 and November 21, 2011 Van earthquakes. The goal of this study is investigated the injury profile of the both earthquakes in relation to musculoskeletal trauma. We retrospectively reviewed medical records of 3,965 patients admitted to in seven hospitals. A large share of these injuries were soft tissue injuries, followed by fractures, crush injuries, crush syndromes, nerve injuries, vascular injuries, compartment syndrome and joint dislocations. A total of 73 crush injuries were diagnosed and 31 of them were developed compartment syndrome. The patients with closed undisplaced fractures were treated with casting braces. For closed unstable fractures with good skin and soft-tissue conditions, open reduction and internal fixation was performed. All patients with open fracture had an external fixator applied after adequate debridement. Thirty one of 40 patients with compartment syndrome were treated by fasciotomy. For twelve of them, amputation was necessary. The most common procedure performed was debridement, followed by open reduction and internal fixation and closed reduction-casting, respectively. The results of this study may provide the basis for future development of strategy to optimise attempts at rescue and plan treatment of survivors with musculoskeletal injuries after earthquakes.

Percutaneous radiofrequency (RF) rhizotomy of the medial branches of the dorsal rami from the spinal nerves is the standard treatment for cervical zygapophyseal joint mediated pain. There is a paucity of data regarding the longevity of analgesia following this procedure. To determine the duration of complete pain relief, analgesic consumption and any adverse events following percutaneous cervical RF rhizotomy. Retrospective chart review of patients who had undergone percutaneous cervical RF rhizotomy for zygapophyseal joint mediated neck pain. Patient reviews were undertaken by the pain consultant at 6 weeks, 6 months and 1 year following the procedure. Where follow-up was incomplete, the patient was assumed only to have had pain relief until their last review where complete pain relief had been documented. Analgesic consumption and any adverse events were recorded. The data was analysed using Microsoft Excel®. At 12 months 63.64% of patients were pain free. Median duration of complete pain relief was 52 weeks. Patients who experienced pain relief had ceased using prescription analgesia by their 6 week review. There were no repeat cervical RF rhizotomies, procedure related infections or unplanned hospital admissions. Percutaneous cervical RF rhizotomy is an effective treatment for cervical zygapophyseal joint mediated neck pain.

Introduction A high-quality health system should deliver care that is free from harm. Few large-scale studies of adverse events have been undertaken in children's healthcare internationally, and none in Australia. The aim of this study is to measure the frequency and types of adverse events encountered in Australian paediatric care in a range of healthcare settings. Methods and analysis A form of retrospective medical record review, the Institute of Healthcare Improvement's Global Trigger Tool, will be modified to collect data. Records of children aged <16 years managed during 2012 and 2013 will be reviewed. We aim to review 6000–8000 records from a sample of healthcare practices (hospitals, general practices and specialists). Ethics and dissemination Human Research Ethics Committee approvals have been received from the Sydney Children's Hospital Network, Children's Health Queensland Hospital and Health Service, and the Women's and Children's Hospital Network in South Australia. An application is under review with the Royal Australian College of General Practitioners. The authors will submit the results of the study to relevant journals and undertake national and international oral presentations to researchers, clinicians and policymakers. PMID:25854978

Reyes, C D; Weber, K J; Gagner, M; Divino, C M

2001-09-01

The totally laparoscopic approach to partial gastrectomy had not been compared previously with results of the open technique. This study compares the results of a series of laparoscopic cases with matched open cases. A retrospective case-matched study was performed in 36 patients (18 laparoscopic surgeries, 18 open surgeries). Each laparoscopic case was matched for patient age and indication for surgery. The intraoperative and postoperative details of the two groups were compared. Laparoscopic surgery resulted in less blood loss, although operative time was increased. Nasogastric tubes were less likely to be used after laparoscopic surgery, and patients in the laparoscopic group had an earlier return to normal bowel function than those in the open group. Length of hospital stay was 2 days shorter in the laparoscopic group. The totally laparoscopic approach to partial gastrectomy is an excellent alternative to the more traditional open approach. It results in a more rapid return of intestinal function and a shorter hospital stay.

Total joint arthroplasty in nonagenarians--a retrospective review of complications and resource use.

LENUS (Irish Health Repository)

Baker, Joseph F

2012-12-01

Increased age brings with it the potential for increased surgical risk. Assessment of specific age cohorts is necessary to plan future service provision and this is the case in hip and knee arthroplasty as the demand for these procedures is anticipated to increase. We retrospectively reviewed the outcomes, including complications, length of stay and blood transfusion rate, in a cohort of 35 nonagenarians undergoing primary or revision total hip and knee arthroplasty. All patients were pre-assessed by anaesthetists before being deemed suitable to undergo surgery in the unit. The mean length of hospital stay was 13.7 +\\/- 10 days (range 2-56). Thirty-one percent of patients required a blood transfusion. Patients who underwent primary total hip arthroplasty reported improved joint specific functional scores. In this appropriately selected group of nonagenarians, we found no evidence to suggest surgery be withheld on the basis of age alone. However, patients with multiple medical comorbidities warrant appropriate assessment and surgical intervention in an institution with appropriate support. Future planning needs to take into account the predicted increase in demand for arthroplasty surgery in this age group.

Timmons, J.H.; Hartshorne, M.F.; Peters, V.J.; Cawthon, M.A.; Bauman, J.M.

1988-01-01

A retrospective review was done of 34 extremities studied between 1981 and 1985 with technetium-99m pyrophosphate scanning; 22 were subsequently amputated. Results of detailed pathologic examination or immediate postoperative examination of the resected extremity were available in 16 cases. In these cases, scanning had allowed correct prediction of the level of amputation and of the specific areas of muscle infarction in 13 cases. In the one case in which amputation was performed for infection rather than muscle necrosis, the lack of necrosis was correctly predicted with the scan. The limited results of this study indicate that the Tc-99m pyrophosphate scan allows the location of necrotic muscle to be predicted accurately and may therefore be a useful adjunct in determining the best level for ultimate amputation. Special caution is required in those cases in which muscle necrosis is due to acute causes (e.g., traumatic thrombosis) rather than chronic vascular disease

Post-traumatic stress disorder (PTSD) is a leading cause of morbidity among military veterans, with up to one-in-five individuals with PTSD also having psychotic symptoms. The current study was designed to determine the association between a known family history of psychiatric illness and risk of developing psychosis in patients with PTSD. Retrospective medical record review was performed on a cohort study of 414 consecutive individuals admitted to the Veteran Administration in 2014 with a diagnosis of military-related PTSD, but without a prior diagnosis of a psychotic disorder. PTSD with psychotic features was defined as the presence of hallucinations, paranoia, other delusions, thought insertion, withdrawal, broadcasting, and/or dissociative episodes. Overall, 22.9% of individuals with PTSD had psychotic symptoms. Having a first-degree relative with bipolar affective and with anxiety disorders was associated with an increased risk of PTSD with psychosis (odds ratio=2.01, 95% confidence interval: 1.01-4.45 and odds ratio=2.72, 95% confidence interval: 1.16-6.41, respectively). A family history of schizophrenia or depression was not associated with risk of developing psychotic features in patients with PTSD. In veterans with military-related PTSD, a familial vulnerability for bipolar disorder and anxiety disorders was associated with an increased risk of developing PTSD with psychotic features. These are preliminary data, given the limitations of a retrospective record review design. These results await replication in future prospective direct family interview studies.

In February 2000, the U.S. Army's Telemedicine and Advanced Technology Research Center (TATRC) and the U.S. Army's Simulation, Training, and Instrumentation Command cohosted an Integrated Research Team conference in Maryland. The goal of the conference was to enable end users, researchers, materiel developers, and other government agencies to present their conceptions of how modeling and simulation could and should be developed to meet military medical needs. During the past 9 years, TATRC has funded more than 175 projects relating to simulation. This study was a retrospective review of TATRC's Modeling and Simulation Training projects (N = 175). Our results show that most (>75%) of the funded projects in this study involved industry. More than 85% of the projects that involved industry focused on technology development. Industry development projects seemed to meet their deliverables in a timely fashion. However, academia projects using industry-developed technologies and prototypes were delayed largely because the technologies did not meet their needs. There seems to be a measurable gap between industry's definition of a completed product technology and academia's ability to implement and use the technology in interactive learning environments. Our findings support the need for a standardized strategic design process that involves a strong industry-academia collaboration and early end-user testing to better facilitate the development of sound requirements that guide technology development.

Is dream recall underestimated by retrospective measures and enhanced by keeping a logbook? An empirical investigation.

Science.gov (United States)

Aspy, Denholm J

2016-05-01

In a recent review, Aspy, Delfabbro, and Proeve (2015) highlighted the tendency for retrospective measures of dream recall to yield substantially lower recall rates than logbook measures, a phenomenon they termed the retrospective-logbook disparity. One explanation for this phenomenon is that retrospective measures underestimate true dream recall. Another explanation is that keeping a logbook tends to enhance dream recall. The present study provides a thorough empirical investigation into the retrospective-logbook disparity using a range of retrospective and logbook measures and three different types of logbook. Retrospective-logbook disparities were correlated with a range of variables theoretically related to the retrospective underestimation effect, and retrospective-logbook disparities were greater among participants that reported improved dream recall during the logbook period. These findings indicate that dream recall is underestimated by retrospective measures and enhanced by keeping a logbook. Recommendations for the use of retrospective and logbook measures of dream recall are provided. Copyright © 2016 Elsevier Inc. All rights reserved.

Hill, Brian; Kambeyanda, Rohan; Fewell, Donna; Bryant, Stewart; Delaney, Kevin O; Herrera, Fernando A

2018-06-01

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.

Study Design Retrospective review with telephone follow-up. Background Acute spondylolytic injuries have a dramatic impact on the young athlete. Excellent short-term clinical outcomes have been observed, but not enough is known about long-term clinical outcomes. Objectives (1) To report long-term clinical outcomes for patients diagnosed with acute spondylolysis, and (2) to assess the prognostic ability of retrospective variables for long-term outcomes. Methods Patients from 2010 through 2013 were retrospectively reviewed to identify patients and to obtain demographic, baseline, and short-term outcomes. Long-term follow-up data were collected by telephone from patients diagnosed with acute spondylolysis to assess recurrence rate of low back pain, perceived outcome, pain, and functional ability. Patients were categorized as having a good or poor long-term outcome based on these measures. Logistic regression analysis was performed to assess the prognostic ability of the retrospective variables for long-term outcomes 3.4 years (range, 1.5-5.6 years) after treatment. Results One hundred twenty-one (71.6%) patients completed the follow-up questionnaire (48 female; mean age at baseline, 14.4 years). At follow-up, 81 (66.9%) patients were able to maintain their same or a higher level of sport. Recurrence of significant symptoms was reported by 55 (45.5%) patients, with 41 (33.9%) requiring medical treatment. The final logistic regression model revealed that female sex, adverse reaction during care, and multilevel injury were significant predictors of poor long-term outcome (R 2 = 0.22). Conclusion Although excellent short-term outcomes were noted, 42% of patients reported a poor outcome at long-term follow-up. Female sex, multilevel injury, and experiencing an adverse reaction during care were significant predictors of poor long-term clinical outcome for patients diagnosed with acute spondylolysis.

Comparing Melanoma Invasiveness in Dermatologist- versus Patient-Detected Lesions: A Retrospective Chart Review

Directory of Open Access Journals (Sweden)

Cindy L. Lamerson

2012-01-01

Full Text Available This study examined whether patient-identified melanomas were more advanced than dermatologist-identified tumors at routine clinic visits, and whether a personal or family history of skin cancer was associated with patterns of detection. A retrospective chart review was performed on melanoma patients (N=201 in a private dermatology clinic. Variables included age, gender, pattern of detection (i.e., patient or a board certified dermatologist, personal or family history of skin cancer, skin type, and previous sun exposure, as well as tumor location and severity. Dermatologist-diagnosed melanomas were less invasive (P<0.0005, and more likely present on the chest, back, and legs (P<0.01. Conversely, patient-identified lesions were more likely to occur on the face, neck and scalp, be associated with younger patients, and a family history of melanoma, but not other types of skin cancer (P<0.01. In a post-hoc analysis examining these factors as predictors of tumor invasiveness, only diagnostic source was significant. Specifically, dermatologist-identified tumors were significantly less invasive than patient-identified tumors. Although age, family history, and tumor location played roles in the early detection of melanomas, the most important factor was diagnostic source. Thus, board-certified dermatologists play a key role in the early detection of malignant melanoma.

The purposes of this study were (1) to determine whether the duration of rest before referral to physical therapy (PT) affects the time to make a full return to activity for patients with an acute spondylolysis, (2) to assess the safety of an early referral to PT in patients with an acute spondylolysis. Retrospective chart review. Hospital-based sports medicine clinic. The medical charts of 196 adolescent athletes (mean age = 14.3 ± 1.8 years) with an acute spondylolytic injury met the inclusion criteria and were reviewed. Patients were subgrouped based on physician referral to PT. An aggressive referral group (10 weeks). Duration of rest before clearance to a full return to activity and the frequency of adverse reactions during the course of treatment. Safety was assessed by calculating the risk of experiencing an adverse reaction in each group. Median days to a full return to activity for aggressive referral group (115.5 days, interquartile range 98-150 days) and conservative referral group (140.0 days, interquartile range 114.5-168 days) were significantly different (P = 0.002). Eleven patients had adverse reactions during the course of treatment. The risk of adverse reaction was not statistically significant between groups (P = 0.509). Patients with acute spondylolysis in the aggressive referral group were able to make a full return activity almost 25 days sooner. No differences in the risk of adverse reactions were noted between aggressive and conservative referral groups.

Objective With the use of teleconferencing for grant peer-review panels increasing, further studies are necessary to determine the efficacy of the teleconference setting compared to the traditional onsite/face-to-face setting. The objective of this analysis was to examine the effects of discussion, namely changes in application scoring premeeting and postdiscussion, in these settings. We also investigated other parameters, including the magnitude of score shifts and application discussion time in face-to-face and teleconference review settings. Design The investigation involved a retrospective, quantitative analysis of premeeting and postdiscussion scores and discussion times for teleconference and face-to-face review panels. The analysis included 260 and 212 application score data points and 212 and 171 discussion time data points for the face-to-face and teleconference settings, respectively. Results The effect of discussion was found to be small, on average, in both settings. However, discussion was found to be important for at least 10% of applications, regardless of setting, with these applications moving over a potential funding line in either direction (fundable to unfundable or vice versa). Small differences were uncovered relating to the effect of discussion between settings, including a decrease in the magnitude of the effect in the teleconference panels as compared to face-to-face. Discussion time (despite teleconferences having shorter discussions) was observed to have little influence on the magnitude of the effect of discussion. Additionally, panel discussion was found to often result in a poorer score (as opposed to an improvement) when compared to reviewer premeeting scores. This was true regardless of setting or assigned reviewer type (primary or secondary reviewer). Conclusions Subtle differences were observed between settings, potentially due to reduced engagement in teleconferences. Overall, further research is required on the psychology of

2013-04-01

Seizures are a hallmark manifestation of tuberous sclerosis complex, yet data characterizing resource utilization are lacking. This retrospective chart review was performed to assess the economic burden of tuberous sclerosis complex with neurologic manifestations. Demographic and resource utilization data were collected for 95 patients for up to 5 years after tuberous sclerosis complex diagnosis. Mean age at diagnosis was 3.1 years, with complex partial and infantile spasms as the most common seizure types. In the first 5 years post-diagnosis, 83.2% required hospitalization, 30.5% underwent surgery, and the majority of patients (90.5%) underwent ≥3 testing procedures. In 79 patients with a full 5 years of data, hospitalizations, intensive care unit stays, diagnostic testing, and rehabilitation services decreased over the 5-year period. Resource utilization is cost-intensive in children with tuberous sclerosis complex and associated seizures during the first few years following diagnosis. Improving seizure control and reducing health care costs in this population remain unmet needs.

This retrospective cohort study reviewed set goals and their outcomes of children and adolescents with severe cerebral palsy who received botulinum toxin A in 2008 and 2009. Sixty children (36 male, mean age 9 years) were included. They received on average 4 (range 1-7) treatments, with the dosage varying between 20 and 400 units per treatment (3-21 U/kg/body weight). Mild transient side effects were reported in 12 of 242 treatments with botulinum toxin A. Treatment goals were related to lower limb function (82%), range of motion (68%), positioning (33%), upper limb function (33%), and facilitating ease of care in dressing (30%), toileting, and diapering (22%). The treatment goals were reached in 60% to 85% by report of the parent and child dyad. Our findings suggest that botulinum toxin A should be considered as a treatment option in patients with cerebral palsy within Gross Motor Function Classification System levels IV and V.

Radiotherapy in stage 1 testicular seminoma: retrospective study and review of literature

International Nuclear Information System (INIS)

Bauduceau, O.; Le-Moulec, S.; Bernard, O.; Souleau, B.; Houlgatte, A.

2003-01-01

Introduction. - Seminoma accounts for about 40% of germ cell tumours of the testicle. In this retrospective analysis, we review literature concerning management of stage I seminoma. Materials and methods. - Between March 1987 and April 2001, 65 patients with stage I pure testicular seminoma received adjuvant radiotherapy with a 25 MV linear accelerator. Results. - Median age was 33 years. Testicular tumour has been found on the right testis in 39 patients and on the left one in 24 patients. Patients have been treated using an anterior-posterior parallel pair and have received 20-25 Gy in 10-14 fractions. The target volume consisted of paraaortic, and paraaortic + homolateral iliac lymph nodes in 17 and 46 patients, respectively. Acute toxicity was mainly digestive, 38% of patients presenting nausea and vomiting. Median follow-up time was 37 months. All patients are alive in complete remission. Discussion. - Because of good radio-sensitivity of seminoma, radiotherapy is regarded as standard adjuvant treatment (5 years relapse rate: 3-5%). Acute toxicity is dominated by moderate gastro-intestinal side effects. Secondary neoplasia represents one of the worst possible long-term complications of therapy. Waiting for ongoing randomized trials, the modern literature for seminoma reflects a trend toward lower radiation doses (20-25 Gy) and smaller treatment volumes (paraaortic field). Adjuvant chemotherapy with two courses of carbo-platin, might be equivalent to radiotherapy but must be investigated in randomized trials. A surveillance policy is one of the other management options less recommended. (author)

This study investigated the amounts of problem-solving process information ("action," "why," "how," and "metacognitive") elicited by means of concurrent, retrospective, and cued retrospective reporting. In a within-participants design, 26 participants completed electrical circuit troubleshooting tasks under different reporting conditions. The method of cued retrospective reporting used the original computer-based task and a superimposed record of the participant's eye fixations and mouse-keyboard operations as a cue for retrospection. Cued retrospective reporting (with the exception of why information) and concurrent reporting (with the exception of metacognitive information) resulted in a higher number of codes on the different types of information than did retrospective reporting.

Full text: A retrospective review of Yttrium 90 synovectomies carried out from June 1997 to February 1999 in Auckland Hospital to determine outcome from the procedure. Methods: Patients were sent a questionnaire for each treated knee The principal outcome measures assessed in the month prior and the 6 months after the Y90 were pain, swelling, walking distance and overall disability score. Referring doctors were sent a questionnaire to provide information on duration of synovitis and treatment. Outcomes measured were presence of effusion 6 months after the Y90, requirement for intra-articular steroid in the 12 months prior to and after the yttrium and change of therapy due lo ongoing symptoms in the treated knee. Results: 29 patients and 40 knees had Y90 during the study period 86% patients with 87.5% knees responded. Referring doctors for 86% patients accounting for 87.5% knees responded. The procedure was well tolerated with the majority of patients reporting nil-mild discomfort during and in the 24 hours after Y90. 86% knees treated reported improvement with a reduction in pain and swelling Patient global assessment reduced from 3.8 to 2.0 while physician global assessment reduced from 3.9 to 3.0. There was an improvement in walking distance 6 months after Y90 with the number of knees able to walk >1km increasing from 2 to 17 14 of 25 patients required a change in treatment because of ongoing problems in the treated knee and one patient has undergone knee joint replacement One further patient is waiting knee joint replacement The need for intra-articular steroid was reduced with 83%, knees having an average of 2.4 steroid injections in the 12 months prior to Y90 compared to 38% knees having an average of 0.7 steroid injections in the 12 months after Y90. Of the 30 knees reporting Improvement 24 knees are at least 12 months post Y90. Of these 50% were Improved at 12 months. As a result of this audit we continue to offer this procedure in the Auckland area, and

High-dose estrogen as salvage hormonal therapy for highly refractory metastatic breast cancer: a retrospective chart review.

Mahtani, Reshma L; Stein, Alisha; Vogel, Charles L

2009-01-01

High-dose estrogens (HDEs) are an efficacious but widely overlooked treatment option for patients with metastatic breast cancer (MBC). This is due in part to the introduction of tamoxifen in the 1970s, which was proven to be equivalent in efficacy and associated with fewer adverse events (AEs). The aim of this study was to report our experience with the use of HDE in postmenopausal women with advanced breast cancer. Local institutional review board approval was obtained to conduct a retrospective chart review of patients with MBC treated with HDEs at the Boca Raton Comprehensive Cancer Center, Boca Raton, Florida, from 2001 through March 2009. Demographic information, response rates, and tolerability profiles were collected. Of the 426 patients with MBC identified, we found 26 patients with MBC who were prescribed HDEs as a treatment in any line of therapy for advanced breast cancer. The median age at the start of HDE therapy was 59 years (range, 42-92 years). Three of the 26 patients (11.5%) were human epidermal growth factor receptor 2-positive determined via fluorescent in situ hybridization analysis. With the exception of 1 patient who had received no prior systemic treatment for metastatic disease, all patients received multiple lines of treatment (both chemotherapy and hormonal treatments) in the advanced setting (median, 7 lines; range, 0-12) prior to the initiation of HDE. Five of 20 patients (25%) with measurable metastatic disease (visceral and/or soft tissue metastases) had objective antitumor responses defined as either a partial response (PR) or a complete response (CR). Four additional patients (20%) had prolonged stable disease (SD) for > or =6 months. Three of 6 patients (50%) with nonmeasurable metastatic disease (bone-only) had prolonged SD for > or =6 months. Clinical benefit rate (defined as CR + PR + SD > or =6 months) for all patients was 46% (12/26), with a median duration of 10 months. Overall median progression-free survival for the 26

Dyspepsia is one of the major indications for upper gastrointestinal endoscopy. Other indications include dysphagia, odynophagia and gastrointestinal bleeding. Endoscopy is an expensive procedure that is out of reach of many patients in resource constrained region such as western Kenya. We reviewed endoscopy records from both public and private health institutions spanning ten years. To determine the pattern of referral and endoscopy diagnoses in patients referred for upper gastrointestinal endoscopy in Eldoret, Kenya. Retrospective chart review. Moi Teaching and Referral Hospital, private hospitals and private clinics in Eldoret, Kenya. One thousand six hundred and ninety (1690) Patients who underwent upper GI endoscopy from 1993 to 2003 were reviewed after obtaining clearances from the respective institutions. Information on age, sex, symptoms, and endoscopy diagnosis were extracted and subjected to statistical analysis. The most common symptom was dyspepsia in 1059 (62.7%) followed by dysphagia in 224 (13.3%). Others were referred with diagnosis of cancer of the stomach or oesophagus. Common endoscopy diagnoses were cancer of the oesophagus in 199 (11.8%) and duodenal ulcer in 186 (11.0%). The majority of the patients (30.4%) had normal endoscopy findings. Of the 1059 patients with dyspepsia, only 154 (14.5%) had duodenal ulcer and 34 (3.2%) had gastric ulcers, the majority, 37.2% had normal endoscopy findings. Dyspepsia was main reason for referral, but the majority of such patients had normal findings. Cancer of the oesophagus was the main diagnosis in patients with dysphagia. In view of the cost of endoscopy, only those with dyspepsia and alarm symptoms be referred for the procedure.

To evaluate the tolerability and clinical effects of subcutaneous (SC) levetiracetam for the treatment of epileptic seizures in a palliative care setting, we conducted a retrospective chart review of patients treated with subcutaneous levetiracetam in the Department of Palliative Medicine at the University Munich, between September 2006 and March 2013. The following parameters were extracted from the charts: reason for antiepileptic drug treatment, daily dose, concentration, infusion rate, co-administration of other drugs, and clinical effects. Furthermore, the charts were screened for signs of adverse drug reactions, e.g., irritation or pain at the infusion site. We identified 20 patients that were treated with levetiracetam SC in the inpatient (n = 7) and outpatient (n = 13) settings. Most patients (n = 17) tolerated the subcutaneous infusion well. Nineteen patients (95%) received levetiracetam in combination with other drugs. These were mainly metamizol (80%), midazolam (75%), and morphine (45%). The median dose of levetiracetam was 95.8 mg/h (SD 37 mg/h), median osmolarity of the infusion solution 2203 mOsmol/L (SD 717 mOsmol/L), and infusion rate 2 mL/h (SD 2.4 ml/h). In 16 patients (80%), seizures were controlled and status epilepticus were interrupted, respectively. We conclude that SC levetiracetam is an effective treatment and well tolerated in the palliative care setting.

Full Text Available Increasing evidence demonstrates an association between health symptoms and exposure to unconventional natural gas development (UNGD. The purpose of this study is to describe the health of adults in communities with intense UNGD who presented for evaluation of symptoms. Records of 135 structured health assessments conducted between February 2012 and October 2015 were reviewed retrospectively. Publicly available data were used to determine proximity to gas wells. Analysis was restricted to records of adults who lived within 1km of a well in Pennsylvania and denied employment in the gas industry (n=51. Symptoms in each record were reviewed by a physician. Symptoms that could be explained by pre-existing or concurrent conditions or social history and those that began or worsened prior to exposure were excluded. Exposure was calculated using date of well drilling within 1km. The number of symptoms/participant ranged from 0 to 19 (mean=6.2; SD=5.1. Symptoms most commonly reported were: sleep disruption, headache, throat irritation, stress or anxiety, cough, shortness of breath, sinus problems, fatigue, nausea, and wheezing. These results are consistent with findings of prior studies using self-report without physician review. In comparison, our results are strengthened by the collection of health data by a health care provider, critical review of symptoms for possible alternative causes, and confirmation of timing of exposure to unconventional natural gas well relative to symptom onset or exacerbation. Our findings confirm earlier studies and add to the growing body of evidence of the association between symptoms and exposure to UNGD.

Air transportation to tertiary care centers of patients with upper extremity amputations has been utilized in hopes of reducing the time to potential replantation; however, this mode of transportation is expensive and not all patients will undergo replantation. The purpose of this study is to review the appropriateness and cost of air transportation in upper extremity amputations. Consecutive patients transported by aircraft with upper extremity amputations in a 7-year period at a level-1 trauma center were retrospectively reviewed. The distance traveled was recorded, along with the times of the injury, referral, transportation duration, arrival, and start of the operation. The results of the transfer were defined as replantation or revision amputation. Overall, 47 patients were identified with 43 patients going to the operating room, but only 14 patients (30%) undergoing replantation. Patients arrived at the tertiary hand surgery center with a mean time of 182.3 minutes following the injury, which includes 105.2 minutes of transportation time. The average distance traveled was 105.4 miles (range, 22-353 miles). The time before surgery of those who underwent replantation was 154.6 minutes. The average cost of transportation was $20,482. Air transportation for isolated upper extremity amputations is costly and is not usually the determining factor for replantation. The type of injury and patients' expectations often dictate the outcome, and these may be better determined at the time of referral with use of telecommunication photos, discussion with a hand surgeon, and patient counseling.

Purpose: Increasing clinical evidence suggests an overrepresentation of gender variance (GV) among patients with autism spectrum disorders (ASDs). This retrospective chart review aims to contribute to the existing literature on co-occurring ASD and gender dysphoria (GD). We compare the rate of parent-reported GV in patients with an ASD diagnosis to that of parent-reported GV in a normative nonreferred data set. Methods: Child Behavior Checklist (CBCL) charts were collected from 492 children and adolescents (409 natal males and 83 natal females) aged 6-18 years who have received a diagnosis of ASD at the New York University Child Study Center. Parent-reported GV was determined through endorsement of CBCL sex item 110, which assesses the presence of gender-related issues. We calculated the odds ratio of endorsement of item 110 between our ASD sample and the CBCL sample data. Results: The subjects diagnosed with ASD were 7.76 times more likely to report GV than the CBCL sample. This finding was statistically significant. About 5.1% of the patients in the ASD group and 0.7% of the CBCL nonreferred group endorsed sex item 110. 5.1% of natal males and 4.8% of natal females endorsed sex item 110. Neither gender nor age influenced the rate of endorsement. Conclusion: This finding supports the growing research suggesting a heightened co-occurrence rate of ASD and GD. Focus should be placed upon improving our understanding of the nature of this co-occurrence and on gender identity development within the atypical development of ASD.

Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

The feline infectious peritonitis virus (FIPV) is a mutated form of the feline enteric coronavirus (FeCV) that can present with a variety of clinical signs. The purpose of this retrospective study was to analyze abdominal ultrasonographic findings associated with cats with confirmed FIPV infection. Sixteen cases were included in the study from a review of medical records at two academic institutions; inclusion was based either on necropsy lesions (n=13) or a combination of histopathological, cytological, and clinicopathological findings highly suggestive of FIPV infection (n=3). The liver was judged to be normal in echogenicity in 11 (69%) cats, diffusely hypoechoic in three cats, focally hyperechoic in one cat, and focally hypoechoic in one cat. Five cats had a hypoechoic subcapsular rim in one (n=3) or both (n=2) kidneys. Free fluid was present in the peritoneal cavity in seven cats and in the retroperitoneal space in one cat. Abdominal lymphadenopathy was noted in nine cats. The spleen was normal in echogenicity in 14 cats and was hypoechoic in two. One cat had bilateral orchitis with loss of normal testicular architecture. Although none of these ultrasonographic findings are specific for FIPV infection, a combination of these findings should increase the index of suspicion for FIPV infection when considered along with appropriate clinical signs.

Full Text Available Background: Idiopathic pulmonary fibrosis (IPF is a chronic, progressive lung disease that usually results in respiratory failure and death. Pirfenidone was approved as the first licensed therapy for IPF in Europe based on phase III trials where patients with a forced vital capacity (FVC >50% of predicted were included. The aim of this study was to characterise patients treated with pirfenidone in Swedish clinical practice and to describe the adherence to the reimbursement restriction since reimbursement was only applied for patients with FVC below 80% of predicted. Methods: This was a retrospective, observational chart review of IPF patients treated with pirfenidone from three Swedish university clinics. Patients initiated on treatment during the period 28 June 2012 to 20 November 2014 were included. Data on patient characteristics, basis of diagnosis, treatment duration, quality of life, and adverse drug reactions (ADRs were collected from medical charts. Results: Forty-four patients were screened and 33 were included in the study. The mean treatment duration from start of pirfenidone until discontinuation or end of study was 38 weeks. At the initiation of pirfenidone treatment, FVC was 62.7% (12.1 [mean (SD], diffusion capacity (DLco was 45.1% (13.8 of predicted, and the ratio of forced expiratory volume on 1 sec (FEV1 to FVC was 0.78 (0.1. The percentage of patients with an FVC between 50 and 80% was 87%. Ten of the patients had ADRs including gastrointestinal and skin-related events, cough and signs of impaired hepatic function, but this led to treatment discontinuation in only two patients. Conclusion: Data from this chart review showed that adherence to the Swedish reimbursement restriction was followed in the majority of patients during the study period. At the start of pirfenidone treatment, lung function, measured as FVC, was lower in the present cohort of Swedish IPF patients compared with other registry and real-life data. About a

Full Text Available Young children with fragile X syndrome (FXS often experience anxiety, irritability, and hyperactivity related to sensory hyperarousal. However, there are no medication recommendations with documented efficacy for children under 5 years old of age with FXS. We examined data through a chart review for 45 children with FXS, 12–50 months old, using the Mullen Scales of Early Learning (MSEL for baseline and longitudinal assessments. All children had clinical level of anxiety, language delays based on MSEL scores, and similar early learning composite (ELC scores at their first visit to our clinic. Incidence of autism spectrum disorder (ASD was similar in both groups. There were 11 children who were treated with sertraline, and these patients were retrospectively compared to 34 children who were not treated with sertraline by chart review. The baseline assessments were done at ages ranging from 18 to 44 months (mean 26.9, SD 7.99 and from 12 to 50 months (mean 29.94, SD 8.64 for treated and not treated groups, respectively. Mean rate of improvement in both expressive and receptive language development was significantly higher in the group who was treated with sertraline (<0.0001 and =0.0071, resp.. This data supports the need for a controlled trial of sertraline treatment in young children with FXS.

Full Text Available Aim: Present study was done with an aim to analyse the clinicopathological and survival characteristics of male breast cancer patients. Methods: We did a retrospective review of our database and analysed total 27 patients who presented to breast oncology unit of Rajiv Gandhi cancer centre and research institute from January 2010 to April 2016. Results: Most common stage at presentation in our study was in stage II. The median follow up was 32.75 months. The actuarial 5-year survival was 92.30% and DFS was 76.30%. Only hormone receptor status was found as a significant prognostic variable among the prognostic factors studied for disease free survival. Conclusions: Carcinoma breast in male is a relatively rare disease and management principles are translated from our understanding of breast cancer in women. A relatively early stage at presentation is a contrasting finding of our series which may be responsible for a significantly better actuarial 5 year survival rates.

The use of sirolimus-based immune suppression in liver transplantation, particularly in hepatitis C virus (HCV)-infected recipients, remains contentious. There is some evidence that sirolimus retards hepatic fibrosis, is renal sparing and may be of benefit in preventing hepatocellular carcinoma (HCC) recurrence. Sirolimus has not been adopted by many transplant centres because of persistent concerns regarding an increased risk of hepatic artery thrombosis, graft loss and death with de novo sirolimus. To review the impact of switching to sirolimus monotherapy in HCV-infected liver recipients with respect to survival, graft loss and hepatic fibrosis. A retrospective review of 190 patients from a single centre undergoing first liver transplantation for HCV over 15 years. 113 patients were switched from calcineurin inhibitor (CNI)-based therapy to low-dose sirolimus monotherapy at a median of 15 months after transplantation for HCV-related fibrosis (72%), renal impairment (14%) or high-risk HCC (5%). Patients switched to sirolimus had improved survival (P diabetes (P = 0.03). These data suggest selective switching to low-dose sirolimus monotherapy in HCV-positive liver recipients improves clinical outcome. © 2014 John Wiley & Sons Ltd.

There has been an increase in observational studies using health administrative data to examine the nature, quality, and costs of care at life's end, particularly in cancer care. To synthesize retrospective observational studies on resource utilization and/or costs at the end of life in cancer patients. We also examine the methods and outcomes of studies assessing the quality of end-of-life care. A systematic review according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and AMSTAR (A Measurement Tool to Assess Systematic Reviews) methodology. We searched MEDLINE, Embase, CINAHL, and York Centre for Research and Dissemination (1990-2011). Independent reviewers screened abstracts of 14,424 articles, and 835 full-text manuscripts were further reviewed. Inclusion criteria were English-language; at least one resource utilization or cost outcome in adult cancer decedents with solid tumors; outcomes derived from health administrative data; and an exclusive end-of-life focus. We reviewed 78 studies examining end-of-life care in over 3.7 million cancer decedents; 33 were published since 2008. We observed exponential increases in service use and costs as death approached; hospital services being the main cost driver. Palliative services were relatively underutilized and associated with lower expenditures than hospital-based care. The 15 studies using quality indicators demonstrated that up to 38% of patients receive chemotherapy or life-sustaining treatments in the last month of life and up to 66% do not receive hospice/palliative services. Observational studies using health administrative data have the potential to drive evidence-based palliative care practice and policy. Further development of quality care markers will enhance benchmarking activities across health care jurisdictions, providers, and patient populations. © The Author(s) 2014.

2016-01-01

INTRODUCTION: Pediatric lung abscesses can be primary or secondary, and there is limited data regarding response to treatments and patient outcomes. OBJECTIVES: To assess the clinical and microbiologic profile of pediatric patients with lung abscess and assess the differences in outcomes for patients treated with medical therapy or medical plus surgical therapy. METHODS: A retrospective review of all pediatric patients ≤ 18 years of age that were treated as an inpatient for lung abscess between the dates of August 2004 and August 2014 was conducted. Patients were divided into two subgroups based on the need for surgical intervention. RESULTS: A total of 39 patients with lung abscess (30 treated with medical therapy alone, 9 also required surgical interventions) were included. Fever, cough, and emesis were the most common presenting symptoms, and most of the patients had underlying respiratory (31%) or neurologic disorders (15%). Staphylococcus aureus was the most common organism in those that had culture results available, and ceftriaxone with clindamycin was the most common combination of antibiotics used for treatment. Comparison of medical and surgical subgroups identified the duration of fever and abscess size as risk factors for surgical intervention. CONCLUSIONS: Pediatric lung abscesses can be managed with medical therapy alone in most cases. Presence of prolonged duration of fever and larger abscess size may be predictive of the need for surgical intervention. Good clinical response to prolonged therapy with ceftriaxone and clindamycin was noted. PMID:27512508

Factors that influence performance of community health workers (CHWs) delivering health services are not well understood. A recent logic model proposed categories of support from both health sector and communities that influence CHW performance and program outcomes. This logic model has been used to review a growth monitoring program delivered by CHWs in Honduras, known as Atención Integral a la Niñez en la Comunidad (AIN-C). A retrospective review of AIN-C was conducted through a document desk review and supplemented with in-depth interviews. Documents were systematically coded using the categories from the logic model, and gaps were addressed through interviews. Authors reviewed coded data for each category to analyze program details and outcomes as well as identify potential issues and gaps in the logic model. Categories from the logic model were inconsistently represented, with more information available for health sector than community. Context and input activities were not well documented. Information on health sector systems-level activities was available for governance but limited for other categories, while not much was found for community systems-level activities. Most available information focused on program-level activities with substantial data on technical support. Output, outcome, and impact data were drawn from various resources and suggest mixed results of AIN-C on indicators of interest. Assessing CHW performance through a desk review left gaps that could not be addressed about the relationship of activities and performance. There were critical characteristics of program design that made it contextually appropriate; however, it was difficult to identify clear links between AIN-C and malnutrition indicators. Regarding the logic model, several categories were too broad (e.g., technical support, context) and some aspects of AIN-C did not fit neatly in logic model categories (e.g., political commitment, equity, flexibility in implementation).

Full Text Available The adrenal gland is a common site of cancer metastasis. Surgery remains a mainstay of treatment for solitary adrenal metastasis. For patients who cannot undergo surgery, radiation is an alternative option. Stereotactic body radiotherapy (SBRT is an ablative treatment option allowing larger doses to be delivered over a shorter period of time. In this study, we report on our experience with the use of SBRT to treat adrenal metastases using Cyberknife technology. We retrospectively reviewed, the Winthrop-University radiation oncology data base to identify 14 patients for whom SBRT was administered to treat malignant adrenal disease. Of the factors examined, the biologic equivalent dose (BED of radiation delivered was found to be the most important predictor of local adrenal tumor control. We conclude that CyberKnife-based SBRT is a safe, non-invasive modality that has broadened the therapeutic options for the treatment of isolated adrenal metastases.

Most small ruminant farms in tropical climates are plagued by Haemonchus contortus, a hematophagous, abomasal parasite. Heavy burdens of this parasite can cause anemia, hypoproteinemia, weight loss, and mortality in susceptible animals. Haemonchus contortus is becoming a major health concern in New World camelids as well, namely llamas (Llama glama) and alpacas (Vicugna pacos), yet little research has been conducted regarding its prevalence or pathology in these species. Herein, we present a retrospective review of llamas and alpacas that were admitted to The University of Georgia Veterinary Teaching Hospital and Athens Diagnostic Laboratory between the years 2002 and 2013. Antemortem fecal egg count (FEC) estimates performed on 30 alpacas were negatively correlated with hematocrit, hemoglobin, and red blood cell count. Total protein was not significantly correlated with FEC. On postmortem examination, 55 of 198 camelids, including 2 from the aforementioned antemortem review, were infected with H. contortus, with llamas (42.6%) having a significantly higher infection rate than alpacas (22.2%). In 15.7% of the total cases, the parasite was the major cause of death. Common gross lesions included peritoneal, thoracic, and pericardial effusions, visceral pallor, subcutaneous edema, and serous atrophy of fat. Histologic lesions included centrilobular hepatic necrosis, hepatic atrophy, lymphoplasmacytic inflammation of the mucosa of the third gastric compartment (C3), extramedullary hematopoiesis in both the liver and spleen, and the presence of nematodes in C3. Our study emphasizes the importance of H. contortus diagnosis and herd monitoring in New World camelids, particularly llamas. © 2016 The Author(s).

Chronic pancreatitis (CP) is a rare disease in Chile, without a clear explanation for this low prevalence. To analyze the characteristics of our patients with pancreatitis. Retrospective analysis of a database of patients with pancreatitis of a clinical hospital. Morphological proof of diagnosis (calcifications/calculi, alterations of ducts, local complication or histology) was obtained for every patient. History of acute pancreatitis was recorded and exocrine-endocrine function was assessed. We retrieved information of 121 patients with pancreatitis (86 males) in a period of 20 years. The number of cases increased markedly every five years. The calculated incidence and prevalence was 0.8/100,000/year and 6/100,000, respectively. Pancreatic calcifications were initially observed in 93 patients and became evident during the follow-up in another six patients. Severe pain or local complications occurred in 27 patients, requiring surgery in 10 or endoscopic treatment in 15. During the years of follow-up, 55 patients were free of symptoms. Exocrine and endocrine insufficiency was demonstrated and treated in 81 and 67 patients, respectively. Alcoholic etiology was evident in 40% of patients. In 29% no etiology was identified. Mapuche origin was exceptional. Late diagnosis of CP is common, since most of our patients presented with advanced stages. Even though CP is increasingly diagnosed in our hospitals, the number of cases is still far fewer when compared to other countries. Underdiagnosis alone cannot explain this difference and genetic factors might be of importance.

AIM: To study how many tumours were visible in restrospect on mammograms originally reported as normal or benign in patients coming to surgery with proven breast cancer. The effect of making the pre--operative mammogram available was also assessed. MATERIALS AND METHODS: Three hundred and twenty initial mammograms of consecutive new breast cancer cases were analysed by a group of radiologists in the knowledge that all patients were later diagnosed with breast cancer. The films were read twice, first without and then with the later (pre-operative) mammograms available. The parenchymal density in the location of the tumour was classified as fatty, mixed or dense, and the tumours were classified as visible or not visible. The reasons for the invisibility of the tumour in the earlier examination were analysed. RESULTS: Fourteen per cent (45) of cancers were retrospectively visible in earlier mammograms without the pre-operative mammograms having been shown, and 29% (95) when pre-operative mammograms were shown. Breast parenchymal density decreased with age and the visibility of tumours increased with age. When considered simultaneously, the effect of age (over 55 vs under 55) was greater (OR = 2.9) than the effect of density (fatty vs others) (OR = 1.5). The most common reasons for non-detection were that the lesion was overlooked (55%), diagnosed as benign (33%) or was visible only in one projection (26%). Growing density was the most common (37%) feature of those lesions originally overlooked or regarded as benign. CONCLUSIONS: Tumours are commonly visible in retrospect, but few of them exhibit specific signs of cancer, and are recognized only if they grow or otherwise change. It is not possible to differentiate most of them from normal parenchymal densities. Saaremaa, I. (2001)

Full Text Available Background: Electroconvulsive therapy (ECT is the one of the oldest and effective treatments in psychiatry today. It has been used in a wide variety of psychiatric disorders in both young and old patients. Aims of the study: The present study is a retrospective chart review of geriatric patients receiving ECT as a treatment option in a tertiary care general hospital psychiatry setting. Methodology: The study evaluated ECT records over a 5-year period between the years 2010 and 2014, and it was observed that 23 elderly patients (aged ≥60 years had received ECT. Results: The patients received modified bitemporal ECT using a brief pulse ECT machine and had no major complications. A total of 184 ECT treatments were administered at an average of 8 treatments per case. The major diagnoses of patients were schizophrenia and major depression. The main indications of ECT were intolerance to medication, suicidal behavior and aggression. Out of the 23 elderly patients, 18 (78.26% showed a good response to ECT. The only complication noted was memory loss and confusion in 3 cases. Patients with medical illnesses like hypertension, diabetes and both together received ECT without any complications. Conclusions: This study adds to the scarce database on the use of ECT in elderly patients in India and adds evidence to the fact that ECT is a safe and effective treatment in the elderly.

OBJECTIVE: To reconsider the routine plastic surgical practice of requesting histopathological evaluation of tissue from gynecomastia. METHOD: The present study was a retrospective histopathological review (15-year period [1996 to 2012]) involving gynecomastia tissue samples received at the pathology laboratory in the Saskatoon Health Region (Saskatchewan). The Laboratory Information System (LIS) identified all specimens using the key search words “gynecomastia”, “gynaecomastia”, “gynecomazia” and “gynaecomazia”. A literature review to identify all cases of incidentally discovered malignancies in gynecomastia tissue specimens over a 15-year period (1996 to present) was undertaken. RESULTS: The 15-year LIS search detected a total of 452 patients that included two cases of pseudogynecomastia (0.4%). Patients’ age ranged from five to 92 years and 43% of the cases were bilateral (28% left sided, 29% right sided). The weight of the specimens received ranged from 0.2 g to 1147.2 g. All cases showed no significant histopathological concerns. The number of tissue blocks sampled ranged from one to 42, averaging four blocks/case (approximately $105/case), resulting in a cost of approximately $3,200/year, with a 15-year expenditure of approximately $48,000. The literature review identified a total of 15 incidental findings: ductal carcinoma in situ (12 cases), atypical ductal hyperplasia (two cases) and infiltrating ductal carcinoma (one case). CONCLUSIONS: In the context of evidence-based literature, and because no significant pathological findings were detected in this particular cohort of 452 cases with 2178 slides, the authors believe it is time to re-evaluate whether routine histopathological examination of tissue from gynecomastia remains necessary. The current climate of health care budget fiscal restraints warrants reassessment of the current policies and practices of sending tissue samples of gynecomastia incurring negative productivity costs on

Mass gathering events can substantially impact public safety. Analyzing patient presentation and transport rates at various mass gathering events can help inform staffing models and improve preparedness. A retrospective review of all patients seeking medical attention across a variety of event types at a single venue with a capacity of 68,756 from January 2010 through September 2015. We examined 232 events with a total of 8,260,349 attendees generating 8157 medical contacts. Rates were 10 presentations and 1.6 transports per 10,000 attendees with a non-significant trend towards increased rates in postseason National Football League games. Concerts had significantly higher rates of presentation and transport than all other event types. Presenting concern varied significantly by event type and gender, and transport rate increased predictably with age. For cold weather events, transport rates increased at colder temperatures. Overall, on-site physicians did not impact rates. At a single venue hosting a variety of events across a 6-year period, we demonstrated significant variations in presentation and transport rates. Weather, gender, event type, and age all play important roles. Our analysis, while representative only of our specific venue, may be useful in developing response plans and staffing models for similar mass gathering venues.

The purpose of our work was to assess the value of abdominal sonography (US) and computed tomography (CT) in the preoperative diagnosis of appendiceal mucocele. We retrospectively reviewed 10 cases of mucocele of the appendix, 7 cases without pseudo myxoma peritonei, and 3 cases with pseudo-myxoma peritonei. All cases were investigated radiologically by plain film and US, barium enema was performed in 3 cases and CT in 5 cases. Mucoceles of the appendix are rare and their clinical presentation is not specific. US confirms the appendicular involvement, but often poses the differential diagnosis with acute inflammation, abscess or localized appendicular peritonitis. CT appears as a mandatory examination since it allows accurate preoperative diagnosis period. In this series, the diagnosis was made preoperatively in the 5 cases where CT had been performed. US is useful to confirm the abnormal pattern of the appendix but does not allow accurate diagnosis of mucocele. CT is more specific and accurate for diagnosis of mucocele of the appendix. (authors)

To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9%) followed by uveitis (862 patients, 15.7%). Uveitis was posterior in 792 patients (91.9% of uveitis) and toxoplasmosis was the most common diagnosis (765 patients, 88.7%). In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

The oral examination is an essential part of the multidisciplinary medical care in elderly people. Oral mucosal lesions and normal variations of oral anatomy (OMLs) are very common in this people, but few studies have examined the frequency and prevalence of these conditions worldwide and less in Chile. The aim of this research was to evaluate the frequency of OMLs in a Chilean elderly population. It was conducted a retrospective study (Talca, Chile). Two hundred seventy-seven OMLs were classified in groups and anatomical sites. In order to contextualize our numbers, we made a systematic review using Publish or Perish software, Google Scholar and InteractiVenn. The most prevalent OMLs groups were soft tissue tumors, epithelial pathology, facial pain and neuromuscular diseases, and dermatologic diseases. The most frequent OMLs included irritation fibroma (30 patients, 10.8%), hemangioma (20, 7.2%), burning mouth syndrome (20 cases, 7.2%), oral lichen planus (12, 4.3%) and epulis fissuratum (12, 4.3%). In the systematic review, 75 OMLs were relevant and the more studied pathologies were traumatic ulcerations (11 of 15 articles), oral lichen planus (10/15), irritation fibroma, melanotic pigmentations, and recurrent aphthous stomatitis (9/10, respectively). Considering all included articles, most frequent OMLs in elderly people included denture-related stomatitis (13.3%), irritation fibroma (8.7%) and fissured tongue (6.3%). The results reflect the frequency of OMLs diagnosed in a specialized service in south of Chile and many countries around the world. These numbers will allow the establishment of preventive politics and adequacy of the clinical services. Key words: Oral mucosal lesions, elderly people, Chilean population, frequency, systematic review.

Full Text Available Abstract Background The purposes of this study are to document psychosocial stressors and medical conditions associated with development of insomnia in school-age children and to report use of hypnosis for this condition. Methods A retrospective chart review was performed for 84 children and adolescents with insomnia, excluding those with central or obstructive sleep apnea. All patients were offered and accepted instruction in self-hypnosis for treatment of insomnia, and for other symptoms if it was felt that these were amenable to therapy with hypnosis. Seventy-five patients returned for follow-up after the first hypnosis session. Their mean age was 12 years (range, 7–17. When insomnia did not resolve after the first instruction session, patients were offered the opportunity to use hypnosis to gain insight into the cause. Results Younger children were more likely to report that the insomnia was related to fears. Two or fewer hypnosis sessions were provided to 68% of the patients. Of the 70 patients reporting a delay in sleep onset of more than 30 minutes, 90% reported a reduction in sleep onset time following hypnosis. Of the 21 patients reporting nighttime awakenings more than once a week, 52% reported resolution of the awakenings and 38% reported improvement. Somatic complaints amenable to hypnosis were reported by 41%, including chest pain, dyspnea, functional abdominal pain, habit cough, headaches, and vocal cord dysfunction. Among these patients, 87% reported improvement or resolution of the somatic complaints following hypnosis. Conclusion Use of hypnosis appears to facilitate efficient therapy for insomnia in school-age children.

Scar endometrioma following obstetric surgical incisions: retrospective study on 33 cases and review of the literature

Directory of Open Access Journals (Sweden)

Guilherme Karam Corrêa Leite

Full Text Available CONTEXT AND OBJECTIVE: The incidence of scar endometrioma ranges from 0.03 to 3.5%. Certain factors relating to knowledge of the clinical history of the disease make correct diagnosis and treatment difficult. The aim here was to identify the clinical pattern of the disease and show surgical results. The literature on this topic was reviewed. DESIGN AND SETTING: Retrospective descriptive study at Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. METHODS: Data from the medical records of patients with preoperative diagnoses of scar endometrioma who underwent operations between 2001 and 2007 were surveyed and reviewed. The postoperative diagnosis came from histopathological analysis. The main information surveyed was age, obstetric antecedents, symptoms, tumor location, size and palpation, duration of complaint, diagnosis and treatment. All patients underwent tumor excision with a safety margin. RESULTS: There were 33 patients, of mean age 30.1 ± 5.0 years (range: 18-41 years. The total incidence was 0.11%: 0.29% in cesarean sections and 0.01% in vaginal deliveries. Twenty-nine tumors (87.9% were located in cesarean scars, two (6.0% in episiotomy scars and two (6.0% in the umbilical region. The main symptom was localized cyclical pain (66.7%, of mean duration 30.5 months (± 23. Surgical treatment was successful in all cases. CONCLUSION: This is an uncommon disease. The most important diagnostic characteristic is coincidence of painful symptoms with menstruation. Patients undergoing cesarean section are at greatest risk: relative risk of 27.37 (P < 0.01. The surgical treatment of choice is excision of the endometrioma with a safety margin.

Full Text Available Aim: Surgical pathology service is generally unavailable in most developing countries and comes with challenges. Cytopathology is a reliable, inexpensive adjunct to surgical histopathology. We present a retrospective review of the various cytopathology cases received at the department. Materials and Methods: A retrospective review of 836 cytopathology cases from January 2010 to December 2011 at the Department of Pathology of our hospital was conducted. All cytopathology reports and records from the department were retrieved and analyzed using the Statistical Package for the Social Sciences version 16 for windows. Results: A total of 836 (mean age 38.18 ± 22.18 cases were reviewed, at an average of approximately 418 cases performed a year (5.7% of the total workload. More than half (58.0% of the cases received had no clinical diagnosis indicated on request forms. Seventy-seven percent (77% of the cases were diagnosed as either definite or nondefinite. The breast was the most aspirated specimen site (20.2%. Benign cases formed 45.0% of all the cases and 29.0% were malignant. There were more benign than malignant cases with respect to all sites aspirated except the breast (18.3%, lymph nodes (35.0%, and soft tissues (11.7% where the reverse occurred. Conclusion: Patronage of cytopathology in Kumasi is increasing and serves as a quick, cheap, and effective alternate means for diagnosis. Improving and expanding on the current practice will ensure that pathologists in practice sustain and improve diagnostic cytopathology and provide material for training young pathologists.

Milsten, Andrew M; Tennyson, Joseph; Weisberg, Stacy

2017-12-01

Moshing is a violent form of dancing found world-wide at rock concerts, festivals, and electronic dance music events. It involves crowd surfing, shoving, and moving in a circular rotation. Moshing is a source of increased morbidity and mortality. The goal of this study was to report epidemiologic information on patient presentation rate (PPR), transport to hospital rate (TTHR), and injury patterns from patients who participated in mosh-pits. Materials and Methods Subjects were patrons from mosh-pits seeking medical care at a single venue. The events reviewed were two national concert tours which visited this venue during their tour. The eight distinct events studied occurred between 2011 and 2014. Data were collected retrospectively from prehospital patient care reports (PCRs). A single Emergency Medical Service (EMS) provided medical care at this venue. The following information was gathered from each PCR: type of injury, location of injury, treatment received, alcohol or drug use, Advanced Life Support/ALS interventions required, age and gender, disposition, minor or parent issues, as well as type of activity engaged in when injured. Attendance for the eight events ranged from 5,100 to 16,000. Total patient presentations ranged from 50 to 206 per event. Patient presentations per ten thousand (PPTT) ranged from 56 to 130. The TTHR per 10,000 ranged from seven to 20. The mean PPTT was 99 (95% CI, 77-122) and the median was 98. The mean TTHR was 16 (95% CI, 12-29) and the median TTHR was 17. Patients presenting from mosh-pits were more frequently male (57.6%; Psurfing was the next most significant, accounting for 20% of presentations. The most common body part injured was the head (64% of injuries). This retrospective review of mosh-pit-associated injury patterns demonstrates a high rate of injuries and presentations for medical aid at the evaluated events. General moshing was the most commonly associated activity and the head was the most common body part injured

2005-01-01

The aim of this study was to look at the visual outcome and treatment complications of children diagnosed with Retinoblastoma during the years 1985-2003 inclusive. A retrospective review of all patients records was performed. Patient characteristics, treatment methods and complications were recorded. Twenty eight children presented to Temple street Hospital between 1985-2003. Six of these infants had bilateral tumours. The mean age at presentation was 23.7 months. Sixty-nine percent presented with Leucocoria, of these 33% also had a squint. The mean duration of symptoms was only known in 58% and this figure was approximately 19.8 months. Enucleation was performed in 24 eyes of 24 patients. Three patients required adjuvant chemotherapy post enucleation. Two eyes was treated with external beam radiation and one eye with plaque radiotherapy. One eye (second eye) was treated with systemic chemotherapy and radiation. Five eyes of three patients were treated with systemic chemotherapy followed by adjuvant Argon laser, cryotherapy and diode laser to each eye.The complications of each treatment group was recorded. The visual outcome in the salvaged eyes was favourable. There were no deaths recorded. Though chemotherapy with adjuvant local treatments provide adequate treatment for early tumours, enucleation still plays a major role in the treatment of Retinoblastoma. The total eye salvage rate in this study was 29% with an enucleation rate of 90% in unilateral cases and 33% in bilateral cases. Sixty-six percent of bilateral eyes affected were salvaged. Seventy-one percent of tumours were diagnosed after a parent noticed a gross abnormality of the eye. This highlights the possible need for screening for retinoblastoma in the infant population.

2017-01-01

The purpose of this retrospective study is to describe the pattern of bribe taking in exchange for release from torture, during and after the decades-long war in Sri Lanka. We reviewed the charts of 98 refugee claimants from Sri Lanka referred to the Canadian Centre for Victims of Torture for medical assessments prior to their refugee hearings in Toronto between 1989 and 2013. We tallied the number of incidents in which claimants described paying cash or jewelry to end torture, and collected other associated data such as demographics, organizations of the perpetrators, locations, and, if available, amounts paid. We included torture perpetrated by both governmental and nongovernmental militant groups. Collected data was coded and evaluated. We found that 78 of the 95 subjects (82.1%) whose reported ordeals met the United Nations Convention Against Torture/International Criminal Court definitions of torture described paying to end torture at least once. 43 subjects paid to end torture more than once. Multiple groups (governmental and non-governmental) practiced torture and extorted money by doing so. A middleman was described in 32 percent of the incidents. Payment amounts as reported were high compared to average Sri Lankan annual incomes. The practice of torture and related monetary extortion was still reported after the end of the war, inclusive of 2013. Torture in Sri Lanka is unlikely to end while profit motives remain unchallenged. As well as health injuries, victims of torture and their families suffer significant economic injuries while their assailants are enriched. The frequent link between torture and impunity means multiple populations the world over are vulnerable to this abuse.

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.

This retrospective project summarizes the types of neoplasms identified in Virginia opossums ( Didelphis virginiana) presented to the University of Tennessee, College of Veterinary Medicine (UTCVM) postmortem service in 1989-2014 and serves as a review of the literature. Of the 85 Virginia opossums identified from the UTCVM case database, there were 17 diagnoses of neoplasia from 12 cases (14%). These cases included 8 females, 2 males, and 2 neutered males. All opossums with known ages (11 of 12) were >2 y old. Pulmonary tumors, specifically minimally invasive or lepidic-predominant adenocarcinomas, were the most common diagnosis and accounted for 53% (9 of 17) of the neoplasms. Additional tumors included acute myeloid leukemia with eosinophil maturation, hepatic hemangiosarcoma, sarcoma (unknown origin), squamous cell carcinoma, disseminated mast cell tumor, trichoblastoma, thyroid adenoma, and an osteoma. These findings serve as a reference for the types of spontaneous neoplasms in Virginia opossums; based on these findings, neoplasia should be considered as a differential in mature captive Virginia opossums.

2015-08-01

A retrospective review was carried out of patients seen at the Haven sexual assault referral centre in South East London between January 2009 and September 2010 to determine the frequency and nature of oral injuries found in people reporting oral rape. Ninety five eligible patients were identified and relevant information was extracted from standardised Haven forms completed during forensic medical examination. The main outcome measures were prevalence, type and location of oral injury. Eighteen (19%) were found to have sustained an oral injury. The most common injury was abrasions, followed by bruising and petechiae. The lips were the most common site of injury followed by the soft palate and the inside of the cheeks. It was concluded that injuries in the mouth were not common after an allegation of oral rape. Injuries were minor and did not require treatment.

Full Text Available We performed a retrospective chart review to examine the progress of patients with depression who received different frequencies of repetitive transcranial magnetic stimulation (rTMS delivered to the left dorsolateral prefrontal cortex (DLPFC. rTMS is a safe and effective alternative treatment for patients with various psychological and medical conditions. During treatment, a coil delivering a time-varying magnetic pulse placed over the scalp penetrates the skull, resulting in clinical improvement. There were 47 patients and three distinct treatment groups found: 10 Hz, 20 Hz, and a separate group who received both frequencies (10/20 Hz. The primary outcome indicator was the difference in Beck Depression Inventory–II (BDI-II scores. Secondary outcomes included categorical indicators of remission, response, and partial response rates as assessed with the BDI-II. In all 3 groups, the majority of patients had depression that remitted, with the highest rate occurring in the 20 Hz group. There were similar response rates in the 10 Hz and 20 Hz groups. There were no patients in the 10/20 Hz group whose depression responded and the highest partial response and nonresponse rates occurred in this group. Although within-group differences were significant from baseline to end of treatment, there were no between-group differences.

Retrospective dosimetry of populations exposed to reactor accident: Chernobyl example, lesson for Fukushima

International Nuclear Information System (INIS)

Chumak, Vadim V.

2013-01-01

Follow-up of the Chernobyl accident had included a good deal of retrospective dosimetry and dose reconstruction. Comparison of Chernobyl and Fukushima shows that despite some differences in course and scale of the two accidents, main elements are present in both situations and Chernobyl experience could be quite educative for better understanding and more optimal handling of Fukushima Dai-ichi accident consequences. This paper contains review of dose reconstruction efforts done to date and extensively published in scientific journals and reports. Specifically the following cases are considered: (i) evaluation of individual doses to evacuees; (ii) validation of ecological dosimetric models and ruling out unconfirmed dose rate measurements; dosimetric support of (iii) case–control study of leukemia among Chernobyl clean-up workers (liquidators), and (iv) cohort study of cataracts among liquidators. Due to limited size of this paper the given application cases are rather outlined while more detailed descriptions could be found in relevant publications. Each considered Chernobyl case is commented with respect to possible application to Fukushima Dai-ichi situation. The presented methodological findings and approaches could be used for retrospective assessment of human exposures in Fukushima. -- Highlights: ► Retrospective dosimetry in Chernobyl was applied for evaluation of individual doses to evacuees. ► Retrospective dosimetry in Chernobyl was applied for validation of ecological dosimetric models, rejection dubious dose rate records. ► Retrospective dosimetry in Chernobyl was applied for risk assessment of leukemia among Chernobyl clean-up workers (liquidators). ► Retrospective dosimetry in Chernobyl was applied for study of cataracts among liquidators. ► Experience of dose reconstruction in Chernobyl could be used for retrospective assessment of exposures in Fukushima

Quality improvement and safety in intensive care are rapidly evolving topics. However, there is no gold standard for assessing quality improvement in intensive care medicine yet. In 2007 a pilot project in German intensive care units (ICUs) started using voluntary peer reviews as an innovative tool for quality assessment and improvement. We describe the method of voluntary peer review and assessed its feasibility by evaluating anonymized peer review reports and analysed the thematic clusters highlighted in these reports. Retrospective data analysis from 22 anonymous reports of peer reviews. All ICUs - representing over 300 patient beds - had undergone voluntary peer review. Data were retrieved from reports of peers of the review teams and representatives of visited ICUs. Data were analysed with regard to number of topics addressed and results of assessment questionnaires. Reports of strengths, weaknesses, opportunities and threats (SWOT reports) of these ICUs are presented. External assessment of structure, process and outcome indicators revealed high percentages of adherence to predefined quality goals. In the SWOT reports 11 main thematic clusters were identified representative for common ICUs. 58.1% of mentioned topics covered personnel issues, team and communication issues as well as organisation and treatment standards. The most mentioned weaknesses were observed in the issues documentation/reporting, hygiene and ethics. We identified several unique patterns regarding quality in the ICU of which long-term personnel problems und lack of good reporting methods were most interesting Conclusion: Voluntary peer review could be established as a feasible and valuable tool for quality improvement. Peer reports addressed common areas of interest in intensive care medicine in more detail compared to other methods like measurement of quality indicators.

Full Text Available Access to treatment for hepatitis C virus (HCV in sub-Saharan Africa is extremely limited. With the advent of direct acting antivirals (DAAs, highly effective and easy-to-deliver oral regimens are now available on the global market. This study was conducted to understand the background and characteristics of a national cohort of patients with HCV infection enrolled in care and awaiting therapy with DAAs.We conducted a retrospective chart review of all adult patients with confirmed HCV infection who were currently enrolled in care and treatment at the four existing hepatitis referral centers in Rwanda. Patient charts at these centers were reviewed, and routinely collected data were recorded and analyzed. Overall, 253 patients were identified; median age was 56 years (IQR: 43, 65, and 149 (58.9% were female. Median viral load was 688,736 IU/ml and 96.7% were HCV genotype 4. As classified by FIB-4 score, 64.8% of the patients had moderate to severe fibrosis. Fibrosis stage was associated with age (OR 1.12, CI 1.09-1.17, but not with time since diagnosis, gender, treatment center, or type of insurance. There was a low frequency of documented co-morbid conditions, including hypertension, diabetes, HIV, and hepatitis B virus.Compared to an estimated 55,000 patients eligible for HCV treatment in Rwanda, this study identified only 253 patients currently diagnosed and engaged in care, highlighting an immense treatment gap in HCV, likely due to the lack of accessible and affordable screening, diagnostic, and treatment modalities. The patients that were enrolled in care had a disproportionately advanced fibrosis stage, possibly indicating late presentation to care or lack of treatment options. In the context of newly available and effective treatment options, this study supports the overall need to accelerate access to HCV screening, diagnostics, and care and treatment services in resource-limited settings in sub-Saharan Africa.

Highlights: •Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). •In this study, twenty-two of the thirty sudden infant death cases showed increasing concentration in the entire lung field. •Based on the autopsy results, the lungs simply collapsed and no other abnormal lung findings were identified. •The radiologist should not consider increasing concentration in all lung fields as simply a pulmonary disorder when diagnosing the cause of infant death using PMCT. -- Abstract: Objectives: Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). However, the lungs often show simply atelectasis at autopsy in the absence of any other abnormal changes. Thus, we retrospectively reviewed the PMCT findings of lungs following sudden infant death and correlated them with the autopsy results. Materials and methods: We retrospectively reviewed infant cases (0 year) who had undergone PMCT and a forensic autopsy at our institution between May 2009 and June 2013. Lung opacities were classified according to their type; consolidation, ground-glass opacity and mixed, as well as distribution; bilateral diffuse and areas of sparing. Statistical analysis was performed to assess the relationships among lung opacities, causes of death and resuscitation attempt. Results: Thirty infant cases were selected, which included 22 sudden and unexplained deaths and 8 other causes of death. Resuscitation was attempted in 22 of 30 cases. Bilateral diffuse opacities were observed in 21 of the 30 cases. Of the 21 cases, 18 were sudden and unexplained deaths. Areas of sparing were observed in 4 sudden and unexplained deaths and 5 other causes of death. Distribution of opacities was not significantly associated with causes of death or resuscitation attempt. The 21 cases with bilateral diffuse opacities included 6 consolidations (4 sudden and unexplained

The PEER test compares drug-free QEEG features for individual patients to a database of patients with similar EEG patterns and known outcomes after pharmacological interventions. Based on specific EEG data elements and historical outcomes, the PEER Report may also serve as a marker of future severe adverse events (eg, agitation, hostility, aggressiveness, suicidality, homicidality, mania, hypomania with specific medications. We used a retrospective chart review to investigate the clinical utility of such a registry in a naturalistic environment.Results: This chart review demonstrated significant improvement on the global assessment scales Clinical Global Impression – Improvement and Quality of Life Enjoyment and Satisfaction – Short Form as well as time to maximum medical improvement and decreased suicidality occurrences. The review also showed that 54.5% of previous medications causing a severe adverse event would have been raised as a caution had the PEER Report been available at the time the drug was prescribed. Finally, due to the significant amount of off-label prescribing of psychotropic medications, additional, objective, evidence-based data aided the prescriber toward better choices.Conclusion: The PEER Report may be

Photodynamic therapy (PDT) with topical δ-aminolevulinic acid (ALA) of non-melanoma skin cancers is often associated with treatment-limiting pain. A previous study on basal cell carcinomas (BCCs) at Roswell Park Cancer Institute evaluated a two-step irradiance scheme as a means of minimizing pain, preserving outcomes, and limiting treatment time. We used an initial low irradiance until 90% of the protoporphyrin IX was photobleached, followed by a high irradiance interval until the prescribed fluence was delivered. Success of this pilot investigation motivated integration of the protocol into routine practice. Here, we present a retrospective review of recent clinical experience in a broad patient population. This was a retrospective review of an existing dermatology database. Fourteen caucasion patients-nine men and five women, ages 18-80, with a total of 51 superficial and 73 nodular BCCs, and three Bowen's disease lesions-were included. ALA was applied to each lesion for approximately 4 hours. Lesions received an initial irradiance of 30-50 mW/cm(2) for 20 J/cm(2) , followed by 150 mW/cm(2) for a total fluence of 200-300 J/cm(2) . Pain was assessed using a visual analog scale (VAS). Clinical outcome was determined at 6-12 months. Median VAS scores were 1.0 for both irradiances. Five of 127 lesions required pain control with 1% xylocaine. Pain was strongly influenced by lesion location but not by lesion type, number, or size. Complete responses were achieved in 84.1% of BCCs, which compares favorably with reported results for single ALA-PDT treatments. Two of three Bowen's disease lesions showed a complete response. Complete responses for nodular BCCs were 37%, which are also within the range of reported outcomes. A two-step irradiance protocol in ALA-PDT effectively minimizes pain, maintains excellent clinical outcomes in superficial lesions, and adds minimal treatment time.

To describe contraceptive use among female adolescents initiating outpatient treatment for opioid use disorder. Retrospective chart review. Outpatient clinic providing medication-assisted treatment for substance use disorders to adolescents and young adults. Nonpregnant female adolescents who presented for treatment from January 1, 2013 to January 31, 2016 (N = 123). None. Prescription contraceptive use at baseline and initiation of a new method within 90 days. Of 123 female adolescents who presented for treatment of opioid use disorder, 113 (91.9%) reported sexual activity and 80 (65.0%) were not using prescription contraception at intake. Previous pregnancy was reported by 43 (35.0%) and 20 (16.3%) were positive for a sexually transmitted infection. Contraceptive counseling was not documented for 73 (59.3%) patients. Among patients with no prescription contraception at baseline, 56 of 80 (70.0%) initiated a method within the study window. Significant predictors (odds ratio [OR]; 95% confidence interval) of contraceptive initiation included previous pregnancy (8.6; 1.39-52.99), education of less than a high school diploma/general equivalency diploma (7.4; 1.63-33.41), and return for follow-up visit (9.8; 2.18-43.69). Young women who presented for opioid use disorder treatment were at high risk of adverse reproductive health outcomes. Most were sexually active and not using prescription contraception. Findings underscore the need for contraceptive counseling in this patient population. Optimally, these services would be provided in conjunction with substance use treatment. Improved contraceptive counseling documentation will allow evaluation of effective contraceptive counseling strategies for adolescents with opioid use disorders and might serve to inform future interventions.

Rolston, Kenneth V I; Nesher, Lior; Tarrand, Jeffrey T

2014-12-01

Patients with solid tumors frequently undergo surgical procedures and develop procedure-related infections. We sought to describe the current microbiologic spectrum of infections at various sites following common surgical procedures. This was a retrospective review of microbiologic data between January 2011 and February 2012. The sites studied were those associated with breast cancer surgery, thoracotomy, craniotomy, percutaneous endoscopic gastrostomy (PEG) tube insertion, and abdominal/pelvic surgery. Only patients with solid tumors were included. A total of 368 surgical site infections (SSIs) were identified (68 breast cancer related; 91 thoracotomy related; 45 craniotomy related; 75 PEG-tube insertion related; and 89 abdominal/pelvic surgery related). Of these, 58% were monomicrobial and 42% were polymicrobial. Overall, 85% of the 215 monomicrobial infections were caused by Gram-positive organisms and 13% by Gram-negative bacilli (GNB). Staphylococcus aureus was the predominant pathogen in monomicrobial infections (150 of 215, 70%). Sixty (40%) of these staphylococcal isolates were methicillin resistant (MRSA), and 65% had a vancomycin minimal inhibitory concentration (MIC) ≥1.0 µg/ml. Pseudomonas aeruginosa was the predominant GNB pathogen (19 of 27, 70%). Staphylococci were also the predominant pathogens in polymicrobial infections, while P. aeruginosa and Escherichia coli were the predominant GNB. Overall, 35% of isolates from polymicrobial infections were GNB. Cephalosporins (e.g., cefazolin) or amoxicillin/clavulanate was used most often for surgical prophylaxis, and 47% of organisms from monomicrobial infections (MRSA, P. aeruginosa) were resistant to them. A similar resistance pattern was observed in polymicrobial infections. Staphylococcus species were isolated most often from the sites studied. Polymicrobial infections (42%) and GNB monomicrobial infections (13%) were relatively frequent causes of SSIs. Many of these infections were caused by

From 2004 to 2013, there were 9341 lawn mower injuries in children under 20 years old. The incidence of lawn mower injuries in children has not decreased since 1990 despite implementation of various different prevention strategies. In this report, the authors review the results of pediatric lawn mower-related lower-extremity injuries treated at a tertiary care referral center as well as review the overall literature. A retrospective review was performed at a level 1 trauma center over a 10-year period (2005-2015). Patients younger than 18 years who presented to the emergency room with lower extremity lawn mower injuries were included. Of the 27 patients with lower-extremity lawn mower injuries during this period, the mean age at injury was 5.5 years and Injury Severity Score was 7.2. Most (85%) patients were boys and the predominant type of mower causing injury was a riding lawn mower (96%). Injury occurred in patients who were bystanders in 78%, passengers in 11%, and operators in 11%. Mean length of stay was 12.2 days, and mean time to reconstruction was 7.9 days. Mean number of surgical procedures per patient was 4.1. Amputations occurred in 15 (56%) cases with the most common level of amputation being distal to the metatarsophalangeal joint (67%). Reconstructive procedures ranged from direct closure (41%) to free tissue transfer (7%). Major complications included infection (7%), wound dehiscence (11%), and delayed wound healing (15%). Mean follow up was 23.6 months and 100% of the patients were ambulatory after injury. The subgroup of patients with the most severe injuries, highest number of amputations, and need for overall surgical procedures were patients aged 2 to 5 years. A review of the literature also showed consistent findings. This study demonstrates the danger and morbidity that lawn mowers present to the pediatric population, particularly children aged 2 to 5 years. Every rung of the so-called reconstructive ladder is used in caring for these

Full Text Available This is a retrospective review of 18 patients with tibial plateau fractures Schatzker type VI. These cases were performed in our medical centre from January 2003 to December 2004. The Ilizarov technique (Russian technique using the ring external fixator was the technique performed. Articular reconstruction and joint alignment were achieved with traction and olive wires with washers. One case required percutaneous elevation of the articular surface and bone grafting through a cortical window. Average clinical union was achieved within 4 months of trauma. Mean final knee flexion was 85°, which is compatible with walking. All patients successfully returned to their previous occupations. In conclusion, the Ilizarov technique has been shown to be a good option and a viable tool in the management of these complex and unstable injuries.

To evaluate indications and outcomes of pediatric keratoplasty in a tertiary eye center, and identify factors that affect visual outcomes.We performed a retrospective review of penetrating keratoplasty in children aged 0 to 18 years between 1995 and 2011 in the Asociación para Evitar la Ceguera en México IAP, Hospital "Dr. Luis Sánchez Bulnes".A total of 574 penetrating keratoplasties were performed during the study interval. Median follow-up was 5.0 years. Main indications included keratoconus (55.58%), postherpetic scarring (9.58%), traumatic opacities (7.49%), and bullous keratopathy (6.09%). Rejection rates at 5 years were 27% overall, and among indications, keratoconus showed the best graft survival at 60-months follow-up (85%). The percentage of patients with best corrected visual acuity (BCVA) posttransplant >20/400 at 5 years in the nonrejection group was 81.25% and 82.74% in 10 years of age (YOA) groups, respectively, versus a BCVA posttransplant > 20/400 at 5 years in the rejection group of 53.68% and 51.72% in 10 YOA groups, respectively. There was a statistically significant reduced rejection rate between genders at 18 months of follow-up, favoring males.Despite being considered a high-risk procedure in children, penetrating keratoplasty can achieve good results, especially in patients with keratoconus. It can achieve significative improvements of visual acuity, provided there is an adequate follow-up and treatment adherence.

Full Text Available IntroductionThe purpose of this retrospective study was to report neurological manifestations noted in patients who were monitored for inflammatory bowel disease, in order to document the pathophysiological, clinical, progressive, and therapeutic characteristics of this entity.Material and methodsWe conducted a retrospective study on patients monitored -in the gastroenterology service in Ibn Sina Hospital in Rabat, Morocco- for inflammatory bowel disease from 1992 till 2013 and who developed neurological manifestations during its course. Patients with iatrogenic complications were excluded, as well as patients with cerebrovascular risk factors.ResultsThere were 6 patients, 4 of whom have developed peripheral manifestations. Electromyography enabled the diagnosis to be made and the outcome was favorable with disappearance of clinical manifestations and normalization of the electromyography.The other 2 patients, monitored for Crohn’s disease, developed ischemic stroke. Cerebral computed tomography angiography provided positive and topographic diagnosis. Two patients were admitted to specialized facilities.ConclusionNeurological manifestations in inflammatory bowel disease are rarely reported.  Peripheral neuropathies and stroke remain the most common manifestations. The mechanisms of these manifestations are not clearly defined yet. Currently, we hypothesize the interaction of immune mediators.

Reporting and analysing the data on medication errors (MEs) is important and contributes to a better understanding of the error-prone environment. This study aims to examine the characteristics of errors submitted to the National Medication Error Reporting System (MERS) in Malaysia. A retrospective review of reports received from 1 January 2009 to 31 December 2012 was undertaken. Descriptive statistics method was applied. A total of 17,357 MEs reported were reviewed. The majority of errors were from public-funded hospitals. Near misses were classified in 86.3 % of the errors. The majority of errors (98.1 %) had no harmful effects on the patients. Prescribing contributed to more than three-quarters of the overall errors (76.1 %). Pharmacists detected and reported the majority of errors (92.1 %). Cases of erroneous dosage or strength of medicine (30.75 %) were the leading type of error, whilst cardiovascular (25.4 %) was the most common category of drug found. MERS provides rich information on the characteristics of reported MEs. Low contribution to reporting from healthcare facilities other than government hospitals and non-pharmacists requires further investigation. Thus, a feasible approach to promote MERS among healthcare providers in both public and private sectors needs to be formulated and strengthened. Preventive measures to minimise MEs should be directed to improve prescribing competency among the fallible prescribers identified.

Full Text Available Purpose. Hand infections are common, usually resulting from an untreated injury. In this retrospective study, we report on hand infection cases needing surgical drainage in order to assess patient demographics, causation of infection, clinical course, and clinical management.Methods. Medical records of patients presenting with hand infections, excluding post-surgical infections, treated with incision and debridement over a one-year period were reviewed. Patient demographics; past medical history; infection site(s and causation; intervals between onset of infection, hospital admission, surgical intervention and days of hospitalization; gram stains and cultures; choice of antibiotics; complications; and outcomes were reviewed.Results. Most infections were caused by laceration and the most common site of infection was the palm or dorsum of the hand. Mean length of hospitalization was 6 days. Methicillin-resistant Staphylococcus aureus, beta-hemolytic Streptococcus and methicillin-susceptible Staphylococcus aureus were the most commonly cultured microorganisms. Cephalosporins, clindamycin, amoxicillin/clavulanate, penicillin, vancomycin, and trimethoprim/sulfamethoxazole were major antibiotic choices. Amputations and contracture were the primary complications.Conclusions. Surgery along with medical management were key to treatment and most soft tissue infections resolved without further complications. With prompt and appropriate care, most hand infection patients can achieve full resolution of their infection.

Management of eight labor and delivery patients dependent on buprenorphine (Subutex™: A retrospective chart review [version 2; referees: 2 approved

Full Text Available Background: Opioid use during pregnancy is a growing concern in the United States. Buprenorphine has been recommended by “The American College of Obstetrics and Gynecology” as an alternative to methadone to decrease risks associated with the use of illicit opioids during pregnancy. The partial μ-opioid agonists’ unique pharmacology, including its long half time and high affinity to the μ-opioid receptor, complicates patient management in a highly kinetic, and often urgent field like obstetric anesthesia. We reviewed our management and outcomes in this medically complex population. Methods: An Institutional Review Board (IRB approved retrospective chart review was conducted of women admitted to the University of Washington Medical Center Labor and Delivery unit from July 2012 to November 2013 using buprenorphine. All deliveries, including intrauterine fetal demise, were included. Results: Eight women were admitted during this period to our L&D floor on buprenorphine. All required peri-partum anesthetic management either for labor and/or cesarean delivery management. Analgesic management included dilaudid or fentanyl PCA and/or continued epidural infusion, and in one instance ketamine infusion, while the pre-admission buprenorphine regimen was continued. Five babies were viable, two women experienced intrauterine fetal death at 22 and 36 weeks gestational age (GSA, respectively, and one neonate died shortly after delivery due to a congenital diaphragmatic hernia. Conclusions: This case series illuminates the medical complexity of parturients using buprenorphine. Different treatment modalities in the absence of evidence-based guidelines included additional opioid administration and continued epidural analgesia. The management of post-cesarean pain in patients on partial μ-opioid agonists remains complex and variable, and evidence-based guidelines could be useful for clinicians to direct care.

Background and PurposeSubclavian artery occlusive disease (SAOD) is often associated with cerebrovascular symptoms such as subclavian steal syndrome and stroke. We conducted a systematic review and meta-analysis to compare percutaneous transluminal angioplasty (PTA) and stent placement for the treatment of SAOD.Materials and MethodsWe searched Medline, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through October 16, 2014. From each study, we abstracted baseline patient characteristics, study design variables, and outcome data including rates of technical success, primary patency (≤2 and >2 years follow-up), symptom resolution, and complications. Meta-analysis was performed using a random-effects model.ResultsA total of 35 non-comparative studies with 1726 patients were included. Technical success rate was significantly higher in the stent group than the PTA group (92.8 vs 86.8 %, p = 0.007). Long-term primary patency rates (76.9 vs 79.6 %, p = 0.729) and symptom resolution rates (82.2 vs 73.0 %, p = 0.327) were not statistically different. There was no statistically significant difference in the rates of stroke or death.ConclusionStent placement for treatment of SAOD may be associated with higher rates of technical success but similar rates of symptom resolution and long-term outcomes. The confidence in the available estimates is low. Further comparative studies are needed to guide patients and clinicians in shared decision making.

Introduction. - Seminoma accounts for about 40% of germ cell tumours of the testicle. In this retrospective analysis, we review literature concerning management of stage I seminoma. Materials and methods. - Between March 1987 and April 2001, 65 patients with stage I pure testicular seminoma received adjuvant radiotherapy with a 25 MV linear accelerator. Results. - Median age was 33 years. Testicular tumour has been found on the right testis in 39 patients and on the left one in 24 patients. Patients have been treated using an anterior-posterior parallel pair and have received 20-25 Gy in 10-14 fractions. The target volume consisted of paraaortic, and paraaortic + homolateral iliac lymph nodes in 17 and 46 patients, respectively. Acute toxicity was mainly digestive, 38% of patients presenting nausea and vomiting. Median follow-up time was 37 months. All patients are alive in complete remission. Discussion. - Because of good radio-sensitivity of seminoma, radiotherapy is regarded as standard adjuvant treatment (5 years relapse rate: 3-5%). Acute toxicity is dominated by moderate gastro-intestinal side effects. Secondary neoplasia represents one of the worst possible long-term complications of therapy. Waiting for ongoing randomized trials, the modern literature for seminoma reflects a trend toward lower radiation doses (20-25 Gy) and smaller treatment volumes (paraaortic field). Adjuvant chemotherapy with two courses of carbo-platin, might be equivalent to radiotherapy but must be investigated in randomized trials. A surveillance policy is one of the other management options less recommended. (author)

The aim of this study was to determine the feasibility of direct transcortical stabilization of fracture dislocations of the mandibular condyle (FDMCs) using narrow-diameter non-threaded Kirschner wire (K-wire). This retrospective review reports on the treatment outcomes for 12 patients (15 fractures) with FDMCs treated with open reduction using transcortical 0.027-inch K-wire stabilization. Postoperative parameters of relevance included infection, facial nerve function, hardware removal, mandibular range of motion, and radiographic determination of fracture union. Three patients had bilateral FDMCs and 9 had unilateral FDMCs (age range at time of injury, 14 to 72 yr; mean age, 32 yr). Postoperative follow-up ranged from 6 weeks to 2 years. Four patients required removal of K-wire hardware for different reasons. K-wires were removed because of infection in 1 patient. Another patient required removal because of migration of the pin into the joint space. One pin was removed electively and another was removed for nonspecific postoperative symptoms that resolved after pin removal. Persistent facial nerve deficit was observed in 1 patient. Open reduction with transcortical K-wire stabilization can achieve satisfactory outcomes for the treatment of FDMC. Further investigation is needed in determining the efficacy of this fixation technique in the management of FDMC. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons.

Childhood allergic contact dermatitis is recognized as a significant clinical problem. The objective was to evaluate the rate of positive patch tests in Israeli children with clinically suspected allergic contact dermatitis, identify possible sex and age differences, compare results with those in Israeli adults, and review pediatric studies in the literature. The study sample included 343 children and adolescents (197 female, 146 male; 1-18 years of age, mean age 11.8 years) with clinically suspected allergic contact dermatitis who underwent patch testing with a standard pediatric series of 23 allergens at a tertiary medical center from 1999 to 2012. Data on clinical characteristics and test results were collected retrospectively from the medical files. Ninety-eight subjects (28.6%) (75 girls [38.1%], 23 boys [15.8%]) had at least one positive reaction. The most frequent reactions were to nickel sulfate, followed by potassium dichromate and cobalt chloride. Nickel sulfate sensitivity was more common in girls, especially those younger than 3 years and older than 12 years. The prevalence of contact sensitization was similar in subjects with and without atopic dermatitis (50% and 51%, respectively). Nickel is the most common allergen in Israeli children, especially girls. Patch testing should be performed in children with clinically suspected allergic contact dermatitis regardless of atopic background. © 2017 Wiley Periodicals, Inc.

Various treatment strategies for low-grade chondrosarcomas with variable outcomes have been reported in the literature. The aim of this study was to assess the oncological and functional outcomes associated with intralesional curettage followed by adjuvant therapy comprising high-speed burring, thermal cauterization, and bone cementation with polymethylmethacrylate. We performed a retrospective review of 21 consecutive patients with intramedullary low-grade chondrosarcoma of long bones treated by intralesional curettage and adjuvant therapy comprising high-speed burring, thermal cauterization, and cementation at our institution from 2007 to 2012. The average age of the patients was 48.7 (range, 18-71) years. There were 7 male and 14 female patients. The mean follow-up period was 58.4 (range, 26-85) months after surgery. The treated lesions were located in the proximal humerus (n=10), proximal tibia (n=6), and distal femur (n=5). At the average follow-up time point of 58.4 (range, 26-85) months, no patient had developed local recurrence and no distant metastases were observed. The average Musculoskeletal Tumor Society score among all 21 patients was 95% (84-100). The combination of intralesional curettage, application of high-speed burring, thermal cauterization, and cementation is an effective treatment strategy for low-grade intramedullary chondrosarcoma of long bones. Excellent oncological and functional results can be obtained.

Objective: To retrospectively review the imaging features of surgically and pathologically confirmed intracranial hemangiopericytoma and anaplastic hemangiopericytoma. Methods: Thirty-nine cases of surgically and pathologically confirmed hemangiopericytoma and anaplastic hemangiopericytoma were analyzed retrospectively. The MRI features were compared with pathological findings in all cases. Results: Of the 39 cases, 21 were anaplastic hemangiopericytoma (WHO grade III) and the remaining cases were hemangiopericytoma (WHO grade II); all lesions were solitary. MRI of anaplastic hemangiopericytoma showed that 20 cases were lobulated, and nine grew cross-leaf. The lesions showed mixed iso-high-low signal (n = 20) or iso-signal (n = 1) on plain T1WI, and mixed high-low signal (n = 20) or iso-signal (n = 1) on plain T2WI. After contrast injection, marked heterogeneous enhancement was seen in 19 cases. Significant necrosis and cystic changes were seen in 16 cases, and the “dural tail sign” was found in two cases. Ten cases had bony destruction, and 16 showed significant peritumoral edema. In 18 cases of hemangiopericytoma, nine were oval-shaped and three grew cross-leaf. The lesions showed mixed iso-low signal (n = 10) or iso-signal (n = 8) on plain T1WI, and mixed iso-high signal (n = 10) or iso-signal (n = 8) on plain T2WI. After contrast injection, significant uniform enhancement was seen in 10 cases. Significant necrosis and cystic changes were seen in seven cases, and “dural tail sign” was seen in six cases. Two cases had bony destruction. No case showed significant peritumoral edema. Pathological immunohistochemical Ki67 staining showed a concentration of ∼18.4% positive cells in anaplastic hemangiopericytoma, whereas in hemangiopericytoma it was 7.12%. Conclusion: Imaging findings of intracranial anaplastic hemangiopericytoma had more pronounced lobulation, cross-leaf growth tendency, more and easier bleeding, more necrosis, more cystic changes giving

Central nervous system (CNS) tumors are the most common cause of cancer-related death in children. Little is known about the demographics and treatment of pediatric brain tumors in low- and middle-income countries (LMICs). We performed a retrospective chart review of all pediatric patients who presented to the neurosurgical service at Tribhuvan University Teaching Hospital in Kathmandu, Nepal from 2009-2014 and collected information on patients tumor. We analyzed age, gender, clinical presentation, extent of surgical resection, histopathology, and length of hospital stay. We also conducted a literature review using specific terminology to capture studies of pediatric neuro-oncologic epidemiology conducted in LMICs. Study location, length of study, sample size, study type, and occurrence of 4 common pediatric brain tumors were extracted. We identified 39 cases of pediatric CNS tumors, with 62.5% observed in male children. We found that male children (median = 13 years) presented later than female children (median = 8 years). The most frequently observed pediatric brain tumor type was ependymoma (17.5%), followed by astrocytoma (15%) and medulloblastoma (15%). Surgical resection was performed for 80% of cases, and gross total resection reported in 62.9% of all surgeries. More than half (54.1%) of patients had symptoms for more than 28 days before seeking treatment. Symptomatic hydrocephalus was noted in 57.1% of children who presented with CNS tumors. The literature review yielded studies from 18 countries. Study length ranged from 2-20 years, and sample sizes varied from 35-1948. Overall, we found more pronounced variation in the relative frequencies of the most common pediatric brain tumors, compared with high-income countries. We present the first operative series of childhood CNS tumors in Nepal. Children often had delayed diagnosis and treatment of a tumor, despite symptoms. More comprehensive data are required to develop improved treatment and management

Radiologically inserted gastrostomy (RIG) is an established way of maintaining enteral nutrition in patients who cannot maintain nutrition orally. The purpose of this study was to evaluate the safety and efficacy of primary placement of a wide bore button gastrostomy in a large, varied patient population through retrospective review. All patients who underwent gastrostomy placement from January 1, 2004 to January 1, 2009 were identified. 18-Fr gastrostomy buttons (MIC-Key G) were inserted in the majority. Follow-up ranged from 6 months to 4.5 years. A total of 260 patients (M:F 140:120, average age 59.2 years) underwent gastrostomy during the study period. Overall success rate for RIG placement was 99.6 %, with success rate of 95.3 % for primary button insertion. Indications included neurological disorders (70 %), esophageal/head and neck malignancy (21 %), and other indications (9 %). Major and minor complication rates were 1.2 and 12.8 %, respectively. Thirty-day mortality rate was 6.8 %. One third of patients underwent gastrostomy reinsertion during the study period, the main indication for which was inadvertent catheter removal. Patency rate was high at 99.5 %. The maximum number of procedures in any patient was 8 (n = 2), and the average tube dwell time was 125 days. Primary radiological insertion of a wide bore button gastrostomy is a safe technique, with high success rate, high patency rate, and low major complication rate. We believe that it is feasible to attempt button gastrostomy placement in all patients, once tract length is within limits of tube length. If difficulty is encountered, then a standard tube may simply be placed instead.

Full Text Available Abstract Background The purpose of this study was to investigate the indications for and approach to hysterectomy at Kingston General Hospital (KGH, a teaching hospital affiliated with Queen's University at Kingston, Ontario. In particular, in light of current literature and government standards suggesting the superiority of vaginal versus abdominal approaches and a high number of concurrent oophorectomies, the aim was to examine the circumstances in which concurrent oophorectomies were performed and to compare abdominal and vaginal hysterectomy outcomes. Methods A retrospective chart audit of 372 consecutive hysterectomies performed in 2001 was completed. Data regarding patient characteristics, process of care and outcomes were collected. Data were analyzed using descriptive statistics, t-tests and linear and logistic regression. Results Average age was 48.5 years, mean body mass index (BMI was 28.6, the mean length of stay (LOS was 5.2 days using an abdominal approach and 3.0 days using a vaginal approach without laparoscopy. 14% of hysterectomies were performed vaginally, 5.9% were laparoscopically assisted vaginal hysterectomies and the rest were abdominal hysterectomies. The most common indication was dysfunctional or abnormal uterine bleeding (37%. The average age of those that had an oophorectomy (removal of both ovaries was 50.8 years versus 44.3 years for those that did not (p Conclusions A significant reduction in LOS was found using the vaginal approach. Both the patient and the health care system may benefit from the tendency towards an increased use of vaginal hysterectomies. The audit process demonstrated the usefulness of an on-going review mechanism to examine trends associated with common surgical procedures.

Methotrexate (MTX) is a common and efficacious systemic agent used for the treatment of moderate to severe psoriasis. Nevertheless, its use is associated with the risk of hepatotoxicity. This study was performed to study the association of MTX dose with regards to hepatotoxicity as evidenced by deranged transaminases. This was a retrospective review of patients with psoriasis on MTX from 2000 to 2009 at the outpatient dermatology clinic, University Malaya Medical Centre (UMMC). We analyzed patients' demography, serial laboratory investigations, liver ultrasounds, and liver biopsies of patients on MTX. Sixty-six of 710 (9.30%) patients with psoriasis were prescribed MTX throughout the 10-year period. Among them 57.6% developed deranged transaminases, with six requiring MTX withdrawal due to hepatotoxicity. The mean cumulative dose of MTX at the detection of liver enzyme derangement was 552.3 ± 596.1 mg. A high proportion of patients on MTX had deranged transaminases. However, the number of serious events was low. We concluded from this study that the use of MTX is relatively safe in patients with moderate to severe psoriasis. © 2013 The International Society of Dermatology.

Does the South African Physiotherapy Journal fulfill the needs of its constituency? A retrospective article review

The greatest number of papers originated in South Africa (81%, 8% from the rest of Africa and 11% written by international authors. Authors with a Masters degree contributed almost 50% of the papers and those with doctorates were responsible for at least 25% of the papers. Most of the papers presented original research (81% with secondary research such as reviews and scholarly papers accounting for 19% of the total. The most common speciality area addressed through research  was  linked  to musculoskeletal  conditions.  The  journal  appears  to  have  provided  an important  platform  for  South African academics and emerging researchers to publish their findings. It is suggested that the journal should give preference to papers that deal with issues that are unique to South Africa and sub-Saharan Africa, as these are the least likely to be published elsewhere. In addition, the journal should emphasise papers that will advance the profession.

Background Access to treatment for hepatitis C virus (HCV) in sub-Saharan Africa is extremely limited. With the advent of direct acting antivirals (DAAs), highly effective and easy-to-deliver oral regimens are now available on the global market. This study was conducted to understand the background and characteristics of a national cohort of patients with HCV infection enrolled in care and awaiting therapy with DAAs. Methods and findings We conducted a retrospective chart review of all adult patients with confirmed HCV infection who were currently enrolled in care and treatment at the four existing hepatitis referral centers in Rwanda. Patient charts at these centers were reviewed, and routinely collected data were recorded and analyzed. Overall, 253 patients were identified; median age was 56 years (IQR: 43, 65), and 149 (58.9%) were female. Median viral load was 688,736 IU/ml and 96.7% were HCV genotype 4. As classified by FIB-4 score, 64.8% of the patients had moderate to severe fibrosis. Fibrosis stage was associated with age (OR 1.12, CI 1.09–1.17), but not with time since diagnosis, gender, treatment center, or type of insurance. There was a low frequency of documented co-morbid conditions, including hypertension, diabetes, HIV, and hepatitis B virus. Conclusions Compared to an estimated 55,000 patients eligible for HCV treatment in Rwanda, this study identified only 253 patients currently diagnosed and engaged in care, highlighting an immense treatment gap in HCV, likely due to the lack of accessible and affordable screening, diagnostic, and treatment modalities. The patients that were enrolled in care had a disproportionately advanced fibrosis stage, possibly indicating late presentation to care or lack of treatment options. In the context of newly available and effective treatment options, this study supports the overall need to accelerate access to HCV screening, diagnostics, and care and treatment services in resource-limited settings in sub

Biological and physical retrospective dosimetry are recognised as key techniques to provide individual estimates of dose following unplanned exposures to ionising radiation. Whilst there has been a relatively large amount of recent development in the biological and physical procedures, development of statistical analysis techniques has failed to keep pace. The aim of this paper is to review the current state of the art in uncertainty analysis techniques across the 'EURADOS Working Group 10-Retrospective dosimetry' members, to give concrete examples of implementation of the techniques recommended in the international standards, and to further promote the use of Monte Carlo techniques to support characterisation of uncertainties. It is concluded that sufficient techniques are available and in use by most laboratories for acute, whole body exposures to highly penetrating radiation, but further work will be required to ensure that statistical analysis is always wholly sufficient for the more complex exposure scenarios.

Introduction: Quality improvement and safety in intensive care are rapidly evolving topics. However, there is no gold standard for assessing quality improvement in intensive care medicine yet. In 2007 a pilot project in German intensive care units (ICUs) started using voluntary peer reviews as an innovative tool for quality assessment and improvement. We describe the method of voluntary peer review and assessed its feasibility by evaluating anonymized peer review reports and analysed the thematic clusters highlighted in these reports. Methods: Retrospective data analysis from 22 anonymous reports of peer reviews. All ICUs – representing over 300 patient beds – had undergone voluntary peer review. Data were retrieved from reports of peers of the review teams and representatives of visited ICUs. Data were analysed with regard to number of topics addressed and results of assessment questionnaires. Reports of strengths, weaknesses, opportunities and threats (SWOT reports) of these ICUs are presented. Results: External assessment of structure, process and outcome indicators revealed high percentages of adherence to predefined quality goals. In the SWOT reports 11 main thematic clusters were identified representative for common ICUs. 58.1% of mentioned topics covered personnel issues, team and communication issues as well as organisation and treatment standards. The most mentioned weaknesses were observed in the issues documentation/reporting, hygiene and ethics. We identified several unique patterns regarding quality in the ICU of which long-term personnel problems und lack of good reporting methods were most interesting Conclusion: Voluntary peer review could be established as a feasible and valuable tool for quality improvement. Peer reports addressed common areas of interest in intensive care medicine in more detail compared to other methods like measurement of quality indicators. PMID:25587245

Over the past few decades, there has been an increase in prevalence of children with autism spectrum disorders (ASD), and those children are now becoming young adults in need of competitive integrated employment (CIE). Customized employment (CE) is one pathway to employment that has been successful for other individuals with developmental disabilities (DD), though research has been very limited on the effectiveness with individuals with ASD. This paper provides a retrospective review of 64 individuals with ASD who came to our program from 2009 to 2014 for supported employment services as referred by the state vocational rehabilitation services agency. Employment specialists engaged in situational assessment, discovery, job development, customized job descriptions, on-site training and support, positive behavioral supports, and job retention techniques. The employment specialists were responsible for tracking their actual time spent working directly with or for the jobseeker with autism spectrum disorders (ASD). All vocational rehabilitation clients with ASD served during this time successfully secured CIE, and maintained their employment with ongoing supports, with intensity of support time decreasing over time. The majority (63/64, 98.4%) of individuals successfully secured CIE through the use of supported employment, in 72 unique employment positions. Of the majority of the individuals who secured employment, 77% (50) individuals indicated that they had never worked before and additional 18% (12) reported having short intermittent histories of employment. Despite this lack of employment experience, in all cases the jobseeker directed the job search and ultimately the job selection. Copyright © 2016 Elsevier Ltd. All rights reserved.

Capturing public opinion on public health topics: a comparison of experiences from a systematic review, focus group study, and analysis of online, user-generated content

Full Text Available BackgroundCapturing public opinion towards public health topics is important to ensure that services, policy and research are aligned with the beliefs and priorities of the general public. A number of approaches can be used to capture public opinion. MethodsWe are conducting a programme of work on the effectiveness and acceptability of health promoting financial incentive interventions. We have captured public opinion on financial incentive interventions using three methods: a systematic review, focus group study, and analysis of online user-generated comments to news media reports. In this short, editorial-style, piece we compare and contrast our experiences with these three methods.ResultsEach of these methods had their advantages and disadvantages. Advantages include tailoring of the research question for systematic reviews, probing of answers during focus groups, and the ability to aggregate a large data set using online user-generated content. However, disadvantages include needing to update systematic reviews, participants conforming to a dominant perspective in focus groups, and being unable to collect respondent characteristics during analysis of user-generated online content. That said, analysis of user-generated online content offers additional time and resource advantages, and we found it elicited similar findings to those obtained via more traditional methods, such as systematic reviews and focus groups. ConclusionsA number of methods for capturing public opinions on public health topics are available. Public health researchers, policy makers and practitioners should choose methods appropriate to their aims. Analysis user-generated online content, especially in the context of news media reports, may be a quicker and cheaper alternative to more traditional methods, without compromising on the breadth of opinions captured.

Cranial irradiation in patients with brain metastasis. A retrospective study of timing

International Nuclear Information System (INIS)

Ampil, F.L.; Burton, G.V.; Mills, G.M.

1999-01-01

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)

The aim of this study was to evaluate the adherence to current guidelines for the investigation of suspected subarachnoid haemorrhage and the prevalence and outcome of computed tomography (CT)-negative aneurysmal subarachnoid haemorrhage. A retrospective review in a single large tertiary referral centre. A total of 796 patients, aged 16-90 years, who underwent lumbar puncture (LP) for suspected subarachnoid haemorrhage (SAH) following a negative or equivocal CT scan between January 2012 and November 2013 (23 months). Xanthochromia reports were obtained using the hospital's department of biochemistry database and clinical data for these patients were reviewed using patient notes. Of 796 CSF reports reviewed, 728 (91%) were negative for xanthochromia, 31 (4%) were positive and 37 (5%) were equivocal. Only 2 out of the 31 patients with positive spectrophotometry results were subsequently found to have an underlying aneurysm on CT angiography. A further 9 out of these 31 patients underwent digital subtraction angiography, with no cerebral aneurysms being detected. Amongst the 37 patients with equivocal xanthochromia reports, 13 underwent CT angiography and only 1 cerebral aneurysm was detected. In patients with clinically suspected SAH but who have negative or questionable CT findings, CSF analysis is likely to be negative in the vast majority of cases, which was 91% in our series. In patients yielding positive or equivocal CSF results the likelihood of an aneurysm being detected is low, amounting to three out of 68 or approximately one in 23 (approximately 4%). Overall in suspected SAH cases where CT scan has been negative, the rate for the detection of cerebral aneurysm is three out of 796 cases (0.4%).

Strategies to prevent mortality from obstetric venous thromboembolism begin with identification, risk stratification and subsequently, implementation of prophylactic measures. We sought to identify the burden of pharmacologic thromboprophylaxis in postpartum women, including the main clinical indications and its uptake in a multireligious population, with Islam as the official religion. A total of 2514 deliveries between 1st January to 31st December 2016, across three centres in Malaysia were reviewed retrospectively from hospital-based registries. 770 (30.62%) patients fulfilled the criteria for thromboprophylaxis based on the revised 2015 criteria proposed by the Royal College of Obstetricians and Gynaecologists. A combination of age, parity, BMI, caesarean section and preterm births were the main indications. One out of the five patients who delivered vaginally required thromboprophylaxis. In our setting with a sizable Muslim population, low molecular weight heparin was the thromboprophylaxis of choice in more than two-third of the patients. The information obtained from this study allows better local resource planning. Impact statement What is already known on this subject: Risk factors for venous thromboembolism in pregnancy and puerperium are largely drawn from registries due to the rarity of the index event. Up to 7% of women require antenatal thromboprophylaxis based on the criteria proposed by the Royal College of Obstetrician and Gynaecologists in 2009. What do the results of this study add: Using the RCOG guideline revised in 2015, a significant proportion of women delivering vaginally would require postnatal thromboprophylaxis based on age, parity and BMI. When either age or parity, both with relatively low odds ratio for thrombosis were omitted, a substantial proportion of women would not achieve the threshold for prophylaxis. Despite a sizable Muslim population in the country, the uptake of low molecular weight heparin was relatively high. What are

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.)

To report a retrospective analysis of data routinely collected in the course of healthcare services at a rural health clinic and to assess obesity incidence and associated interventions among rural Mexican-American adolescents. Two hundred and twelve charts reviewed; 98 (46.2%) males and 114 (53.8%) females. Data extracted included Medicaid exams conducted at the clinic within 5 years. Equal overweight or obese (n = 105, 49.5%), versus normal BMI categorizations (n = 107, 50.5%) documented overall and by gender. Female obesity higher (25.4%) than national norms (17.4%); male rates (25.5%) were within national norm. Interventions provided by nurse practitioners (94%) for 34.8%-80% of overweight/obese had limited follow-up (4%). Obesity incidence markedly increased between 13 and 18 years of age without associated interventions; 51.4%-75.6% without interventions. Obesity is a healthcare problem among rural Mexican-American adolescents accessing care at the rural health clinic. Obesity intervention and follow-up was suboptimal within this setting. Rural and ethnic minority adolescents experience health disparities concerning obesity prevalence and remote healthcare access. Obesity prevention and treatment during adolescence is a national health priority given physiologic and psychological tolls on health and potential for obesity into adulthood. Obesity assessment and translation of evidence-based interventions for rural Mexican-American adolescents at rural health clinics is implicated. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

Objective The aim of this study was to investigate the clinical features, laboratory findings, systemic manifestations, treatment and outcome of patients with bullous systemic lupus erythematosus in a tertiary care center in Thailand. Methods We performed a retrospective review from 2002 to 2014 of all patients who fulfilled the diagnostic criteria for bullous systemic lupus erythematosus to evaluate for the clinical characteristics, extracutaneous involvement, histopathologic features, immunofluorescence pattern, serological abnormalities, internal organ involvement, treatments and outcome. Results Among 5149 patients with cutaneous lupus erythematosus and/or systemic lupus erythematosus, 15 developed vesiculobullous lesions. Ten patients had validation of the diagnosis of bullous systemic lupus erythematosus, accounting for 0.19%. Bullous systemic lupus erythematosus occurred after the diagnosis of systemic lupus erythematosus in six patients with a median onset of 2.5 months (0-89). Four out of 10 patients developed bullous systemic lupus erythematosus simultaneously with systemic lupus erythematosus. Hematologic abnormalities and renal involvement were found in 100% and 90%, respectively. Polyarthritis (40%) and serositis (40%) were less frequently seen. Systemic corticosteroids, immunosuppressants, antimalarials and dapsone offered resolution of cutaneous lesions. Conclusion Bullous systemic lupus erythematosus is an uncommon presentation of systemic lupus erythematosus. Blistering can occur following or simultaneously with established systemic lupus erythematosus. We propose that clinicians should carefully search for systemic involvement, especially hematologic and renal impairment, in patients presenting with bullous systemic lupus erythematosus.

Full Text Available Objectives: To investigate the incidence of parasitic infestations and inflammation accompanying parasitosis in a series of appendectomy cases. Methods: Six-hundred-sixty patients who had undergone appendectomy in Bingöl State Hospital, Bingol, Turkey with the preliminary diagnosis of appendicitis between January 2012 and February 2015 were included in this retrospective study. They were retrospectively evaluated in terms of age, gender and pathological findings. Cases diagnosed with parasitic infestations were re-evaluated histopathologically for inflammatory response. Results: The mean age was 19.6 years, and the male/female ratio was 1.8. When evaluated in terms of histopathological diagnoses, 573 (86.8% were diagnosed as acute appendicitis, and parasitic infestation was identified in 12 (1.8%. Among cases with parasitic infestation, Enterobius vermicularis was identified in 9 (75% and Taenia in 3 (25% cases. Of cases with Enterobius vermicularis, 4 (44.4% had lymphoid hyperplasia, 1 (11.1% had normal-structured appendix vermiformis, and 4 (44.4% had findings of acute appendicitis. All cases with taeniasis had an inflammatory response: acute appendicitis was identified in 2 (66% and acute gangrenous appendicitis in 1 (33% of them. Conclusion: Parasitic infestations are among the probable causes in appendicitis etiology and should be kept in mind during differential diagnosis. However, whether every parasitic infestation leads to appendiceal inflammatory response is controversial.

Kerstman, Eric

2009-01-01

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

Evidence suggests that individuals with Alzheimer's disease (AD) are often diagnosed in the later stages of their disease with a poor prognosis. This study aimed to identify patterns in signs and symptoms preceding the clinical diagnosis of AD to suggest a predictive model for earlier diagnosis of the disease in the primary care. A retrospective medical record review; nested case control design. Participants included one hundred and nine patients from three general practice (GP) surgeries in Milton Keynes and Luton Clinical Commissioning groups (CCG) (37 cases with AD and 72 controls without AD). A retrospective analysis using the logistic regression of the presence of signs and symptoms before the diagnosis of AD was attained. Identification of the timing and sequence of appearance of these presentations as first reported before the clinical diagnosis was measured. Episodic memory with an odds ratio of 1.85 was the most frequent presentation, documented in 1.38% of the controls and 75.6% in cases. Auditory disturbance with an odds ratio of 3.03, which has not previously been noted except in the form of auditory hallucination, could have a diagnostic value. Auditory disturbance, which occurred mostly in the Caucasian females, could discriminate individuals with AD from those without. The symptom, which presented up to 14.5 (mean time) years prior to clinical diagnosis, was identified in Caucasians and mixed race individuals only.

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.

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.

Fibromyalgia is associated with substantial functional disability. Current drug and non-drug treatments result in statistically significant but numerically small improvements in typical numeric measures of pain severity and fibromyalgia impact. The aim of the present study was to evaluate additional measures of pain severity and functional outcome that might be affected by fibromyalgia treatment. This retrospective review evaluated outcomes from 274 adults with fibromyalgia who participated in a six-week, multidisciplinary treatment programme. Pain and function were evaluated on the first and final treatment visit. Pain was evaluated using an 11-point numerical scale to determine clinically meaningful pain reduction (decrease ≥ 2 points) and from a pain drawing. Function was evaluated by measuring active range of motion (ROM), walking distance and speed, upper extremity exercise repetitions, and self-reports of daily activities. Numerical rating scores for pain decreased by 10-13% (p Fibromyalgia Impact Questionnaire (FIQ) scores decreased by 20% (p fibromyalgia treatment effectiveness. © 2013 John Wiley & Sons, Ltd.

Purpose: The principle objective of this study is to determine the role of radiation therapy in the management of pilocytic astrocytoma. The specific aims are to assess the results of surgical resection +/- radiation therapy, the dose-response relationships for local tumor control, and the prognostic indicators. Materials and methods: Between Jan. 1970 and Dec. 1995, 60 patients with pilocytic astrocytomas (27 cerebellum, 23 hypothalmus/brain stem, 4 temporal, 3 frontal, and 3 occipital) were seen. All pathologic slides were reviewed and confirmed. Of these, 30 patients had surgery only (8 subtotal resections and 22 total resections), 8 had biopsy followed by radiotherapy (6) or chemotherapy (2), 21 had surgery and postoperative radiotherapy (20 subtotal resections and 1 total resection) and 1 was observed only. The radiation dose was 40.6 Gy/31fr/44ds to 60.2 Gy/35fr/49ds (mean = 52.1 Gy). Results: The overall 5- and 10-year actuarial survival rate was 93% and 93%, and the relapse-free survival rate was 86% and 80%, respectively. Eight patients developed local recurrence and one had leptomeningeal spread. Two patients receiving chemotherapy (vincristine + carboplatin) had persistent but stable disease. The one patient who was observed eventually required surgical resection 25 months later. Subtotal resection without RT: The local recurrence rate was 38% ((3(8))) if no RT was given after subtotal resection. Only 2 of the 3 recurrences were salvaged. All 22 patients who had tumor totally resected had local tumor control. Subtotal resection/biopsy only plus RT: Radiation therapy was effective in controlling the gross disease in 75% ((15(20))) of patients with subtotal resection, and 100% ((6(6))) of patients with biopsy only. In 14 patients receiving a tumor dose ≥ 51 Gy, 13 (93%) had local control, in comparison, to (11(15)) (73%) receiving a tumor dose <51 Gy had tumor control. Location of tumor: Sixty-three percent ((17(27))) of patients with tumor in cerebellum

In the United States, 38.5 million people are foreign-born, one in three arriving since 2000. Health issues include high rates of hepatitis B, humanimmunodeficiency virus infection, parasitic infections, and M. tuberculosis. We sought to determine rates of provider adherence to accepted national guidelines for immigrant and refugee health screening and vaccines done at the primary care clinics at Boston Medical Center. Randomized, retrospective chart review of foreign born patients in the primary care clinics. We found low screening and immunization rates that do not conform to CDC/ACIP guidelines. Only 43 % of immigrant patients had tuberculosis screening, 36 % were screened for HIV and hepatitis B, and 33 % received tetanus vaccinations. Organizational changes incorporating multi-disciplinary approaches such as creative use of nursing staff, protocols, standing orders, EMR reminders, and web based educational tools can contribute to better outcomes by identifying patients and improving utilization of guidelines.

To review the Royal College of Pathologists of Australasia (RCPA) Quality Assurance Program Dermatopathology module from 2005 to 2016 to assess diagnostic performance, changes over time, and areas of diagnostic difficulty. The computerized records of the RCPA Dermatopathology subspecialist module were reviewed. Cases were categorized into groups including nonneoplastic disorders, neoplasms, and cases with multiple diagnoses. The performance of participants over time in each of these categories and in more specific areas (including melanocytic and adnexal neoplasms) was assessed. Cases which showed high rates of discordant responses were specifically reviewed. One hundred sixteen cases circulated over 10 years were evaluated. The overall concordance rate was 77%, with a major discordance rate of 7%. There was a slightly higher concordance rate for neoplasms compared with nonneoplastic lesions (80% vs. 74%). Specific areas associated with lower concordance rates included classification of adnexal tumors and identification of multiple pathologies. A spindle cell nevus of Reed yielded a 40% discordance rate, with most misclassifications indicating melanoma. The RCPA quality assurance program module has circulated a wide range of common and uncommon cases to participants over the 12 years studied, highlighting a low but important rate of major discordant responses. Melanocytic lesions, hematolymphoid infiltrates, adnexal tumors, and identification of multiple pathologies are identified as areas worthy of particular attention in quality improvement activities.

Terminally ill patients are at high risk of pressure ulcers, which have a negative impact on quality of life. Data about pressure ulcers' prevalence, incidence and associated factors are largely insufficient. To document the point prevalence at admission and the cumulative incidence of pressure ulcers in terminally ill patients admitted to an Italian home palliative care unit, and to analyse the patients' and caregivers' characteristics associated with their occurrence. Retrospective chart review. Patients ( n = 574) with a life expectancy ⩽6 months admitted to a palliative home care service were included in this study. The prevalence and incidence rates were 13.1% and 13.0%, respectively. The logistic regression models showed body mass index ( p 70 and >1 caregiver at home as the dichotomous variables predictors of presenting with a pressure ulcer at time of admission and during home palliative care. The notable pressure ulcers' incidence and prevalence rates suggest the need to include this issue among the main outcomes to pursue during home palliative care. The accuracy of body mass index, Braden Scale and Karnofsky Performance Scale in predicting the pressure ulcers risk is confirmed. Therefore, they appear as essential tools, in combination with nurses' clinical judgment, for a structured approach to pressure ulcers prevention. Further research is needed to explore the home caregivers' characteristics and attitudes associated with the occurrence of pressure ulcers and the relations between their strategies for pressure ulcer prevention and gender-related patient's needs.

Myelofibrosis (MF) is a clonal hematopoietic malignancy characterized by constitutional and localized symptoms, progressive splenomegaly, bone marrow fibrosis, and cytopenias. Although MF is well studied, few studies exist regarding its symptomatic burden in routine clinical practice. This study aimed to characterize symptoms and other clinical features of MF among patients in the United States. We conducted a retrospective medical record review of adult patients with an MF diagnosis between 1 January 2005 and 31 March 2010, stratified by the presence of palpable splenomegaly. Eligible patients had 12 months or more of follow-up after diagnosis (or after detection of splenomegaly, if present) unless death occurred. Demographic and clinical characteristics, MF-related symptoms, and treatments were reported by treating physicians. We report on 180 MF patients: 102 with splenomegaly, 78 without. Median age was 66 years, 63% were male, and 82% had intermediate-2 or high-risk MF (International Prognostic Scoring System). Fatigue was reported by ∼85% of patients; weight loss, night sweats, and fever (any grade) were each reported by 50% or more of patients. Generalized abdominal pain, left subcostal pain, and early satiety occurred more frequently among patients with splenomegaly. Multiple symptoms were reported by 95% of patients. Common comorbidities were hypertension, diabetes, and chronic pulmonary disease. Symptoms are common in MF patients, regardless of the presence of palpable splenomegaly. Careful assessment of symptom burden is an important aspect of the clinical evaluation of patients with MF

To determine the prevalence, risk factors, co-morbidities and case fatality rates of Protein Energy Malnutrition (PEM) admissions at the paediatric ward of the University of Nigeria Teaching Hospital Enugu, South-east Nigeria over a 10 year period. A retrospective study using case Notes, admission and mortality registers retrieved from the Hospital's Medical Records Department. All children aged 0 to 59 months admitted into the hospital on account of PEM between 1996 and 2005. A total of 212 children with PEM were admitted during the period under review comprising of 127 (59.9%) males and 85 (40.1%) females. The most common age groups with PEM were 6 to 12 months (55.7%) and 13 to 24 months (36.8%). Marasmus (34.9%) was the most common form of PEM noted in this review. Diarrhea and malaria were the most common associated co-morbidities. Majority (64.9%) of the patients were from the lower socio-economic class. The overall case fatality rate was 40.1% which was slightly higher among males (50.9%). Mortality in those with marasmic-kwashiokor and in the unclassified group was 53.3% and 54.5% respectively. Most of the admissions and case fatality were noted in those aged 6 to 24 months which coincides with the weaning period. Marasmic-kwashiokor is associated with higher case fatality rate than other forms of PEM. We suggest strengthening of the infant feeding practices by promoting exclusive breastfeeding for the first six months of life, followed by appropriate weaning with continued breast feeding. Under-five children should be screened for PEM at the community level for early diagnosis and prompt management as a way of reducing the high mortality associated with admitted severe cases.

Full Text Available Purpose: To compare the success rates of external dacryocystorhinostomy (EXT-DCR with 5-fluorouracil (5-FU augmented endonasal laser dacryocystorhinostomy (ENL-DCR and to record the complications associated with 5-FU augmented ENL-DCR Materials and Methods: This was a retrospective non-randomised study. Forty-one patients with primary acquired nasolacrimal duct obstruction underwent an EXT-DCR (19 patients or an ENL-DCR (22 patients over a 3-year period. A Holmium YAG laser (Ho:YAG was used in the latter group of patients. Silicone tubes intubated in all patients were removed at three months. 5-FU was applied intraoperatively at the site of the ostium in the ENL-DCR patients. The median follow-up was 12 months (range 3-24 months for the ENL-DCR group and 22 months (range 6-28 months for the EXT-DCR group. The patency of the lacrimal system and the severity of epiphora were assessed at a final-review. Results: The median age of the EXT-DCR group was 77 years (range 53-87 and that of the ENL-DCR group was 71 years (range 23 to 84. There were 12 female patients in the former group and 19 in the latter. The percentage of success in the EXT-DCR group was 94.7% (95% confidence interval (CI = 75.4-99.1 = , and 63.6% in the ENL-DCR group (95% CI= 43.0-80.3. The confidence interval for the difference of 31.1% was 5.6-52.2. There was a statistically significant difference between the two groups, p=0.024 (Fisher exact test. Conclusions: These data suggest that EXT-DCR provides better results than 5-FU augmented ENL-DCR. However, ENL-DCR is the procedure of choice in certain circumstances such as in elderly, frail or medically unfit patients. Our results of 5-FU augmented ENL-DCR compare favourably with other published series.

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.

Congenital hypothyroidism (CH), as indicated by an elevation of capillary thyroid-stimulating hormone (TSH) at newborn screening, is a preventable cause of mental retardation with varying aetiology; it can be transient or permanent. Radionuclide assessment is currently the gold standard for imaging CH. This study aimed to (i) review the different scintigraphic patterns and correlate them with TSH levels/patient outcomes, (ii) assess the role of sonography in neonates with apparent agenesis as indicated by scintigraphy and (iii) develop a diagnostic investigative algorithm. The technetium thyroid scans of 83 consecutive patients (49 females, average age 32 days) with CH scanned between 2005 and 2009 were retrospectively reviewed. Two nuclear medicine physicians blinded to the clinical details interpreted the scans in consensus. Scintigram appearances were categorised into five groups. Patients scintigraphically diagnosed with thyroid agenesis were evaluated with ultrasound. TSH values and scintigraphic and sonographic findings were correlated with patients' final diagnosis. Based on scintigraphy, 14, 13 and 19 patients out of 83 were assessed as having normal thyroid sites with normal, increased and decreased uptake, respectively. Twenty-two of 83 patients had no uptake, and 15 of 83 patients had ectopic uptake. Higher median TSH levels were seen in no-uptake and ectopic uptake subgroups. Eighteen of 22 patients with no uptake were evaluated with ultrasound. Three of the 18 patients had a normal thyroid gland, and three of 18 patients had a hypoplastic thyroid. Scintigram findings in patients with congenital hypothyroidism fall into five major categories, which have therapeutic implications (lifelong thyroxine in agenesis versus trial of stopping thyroxine in other subgroups). Sonographic demonstration of thyroid tissue in patients scintigraphically diagnosed with thyroid agenesis has major management implications.

To review the epidemiology, diagnosis and changing treatment paradigm of ocular candidiasis, and report current prevalence rates and risk factors at one inpatient hospital. Retrospective review; systematic literature review. All Wills Eye Institute inpatient ophthalmology consultations from Thomas Jefferson University Hospital were retrospectively reviewed between June 2006 and November 2006. All consultations for candidaemia were included. The outcome variables included chorioretinitis, endophthalmitis, visual symptoms and Candida speciation. The ophthalmic literature was reviewed using PubMed. Keywords included Candida, candidaemia, chorioretinitis, vitritis and endophthalmitis. Bibliographies were manually searched. Three of the 38 consultations for candidaemia (7.9%) had chorioretinitis. There were no cases of vitritis or endophthalmitis. The presence of symptoms, or the inability to articulate symptoms, was significantly associated with risk of ocular candidiasis (p = 0.003). All three cases of chorioretinitis had positive blood cultures for Candida albicans (p = 0.089) and were treated with oral fluconazole. Various factors have led to the increasing prevalence of inpatient candidaemia. Risk factors for ocular involvement include albicans species and the presence of, or inability to articulate, visual symptoms. For those without abnormal findings on initial examination, a subsequent retinal examination should be performed in 2 weeks, particularly if new symptoms develop or if the patient is unable to relay symptoms. Patients with chorioretinitis should be treated with systemic antifungal agents. For those with vitritis or endophthalmitis, particularly if worsening on systemic therapy alone, intravitreal antifungal medications or early vitrectomy should be considered.

The increasing use of serial PET/CT scans in the management of pediatric malignancies raises the important consideration of radiation exposure in children. To estimate the cumulative radiation dose from PET/CT studies to children with malignancy and to compare with the data in literature. Two hundred forty-eight clinical PET/CT studies performed on 78 patients (50 boys/28 girls, 1.3 to 18 years old from December 2002 to October 2007) were retrospectively reviewed under IRB approval. The whole-body effective dose (ED) estimates for each child were obtained by estimating the effective dose from each PET/CT exam performed using the ImPACT Patient Dosimetry Calculator for CT and OLINDA for PET. The average number of PET/CT studies was 3.2 per child (range: 1 to 14 studies). The average ED of an individual CT study was 20.3 mSv (range: 2.7 to 54.2), of PET study was 4.6 mSv (range: 0.4 to 7.7) and of PET/CT study was 24.8 mSv (range: 6.2 to 60.7). The average cumulative radiation dose per patient from CT studies was 64.4 mSv (range: 2.7 to 326), from PET studies was 14.5 mSv (range: 2.8 to 73) and from PET/CT studies was 78.9 mSv (range: 6.2 to 399). The radiation exposure from serial PET/CT studies performed in pediatric malignancies was considerable; however, lower doses can be used for both PET and CT studies. The ALARA principle must be applied without sacrificing diagnostic information. (orig.)

Docetaxel, a lipophilic drug, is indicated for castration-resistant metastatic prostate cancer. Most men with such disease would have had androgen-deprivation therapy, which decreases muscle and increases body fat. Obesity and body composition changes may influence the outcomes of docetaxel therapy. We conducted a retrospective review of 333 patients with metastatic prostate cancer treated with docetaxel at a comprehensive cancer center between October 7, 2004 and December 31, 2012. Body composition parameters were measured based on the areas of muscle and adipose tissues in the visceral and subcutaneous compartments on CT images at L3-4 levels. Dose calculations, toxicity and adverse reaction profiles, and overall survival were analyzed. Obese patients were younger at the diagnosis of prostate cancer and had a shorter duration from diagnosis to docetaxel therapy. Analysis of body composition found that a high visceral fat-to-subcutaneous fat area ratio (VSR) was associated with poor prognosis but a high visceral fat-to-muscle area ratio (VMR) and high body mass index were associated with increased duration from starting docetaxel to death, allowing such men to catch up with patients with normal body mass index in overall survival from cancer diagnosis to death. Cox proportional hazard regression showed that age ≥65 years, high VSR, abnormal serum alkaline phosphatase, and >10% reduction of initial dosage were significant predictors of shorter time between starting docetaxel and death, and that high VMR, obesity, and weekly regimens were significant predictors of longer survival after docetaxel. Obese and overweight patients may benefit more from weekly docetaxel regimens using the reference dosage of 35 mg/m2 without empirical dosage reduction.

PurposeDue to high thrombus load, acute stroke patients with tandem obstructions of the extra- and intracranial carotid arteries or the middle cerebral artery show a very limited response to systemic thrombolysis. Interventional treatment with mechanical thrombectomy—often in combination with acute stenting of underlying atherosclerotic stenosis or dissection—is increasingly used. It has been shown that such complex interventions are technically feasible. The lack of optimal management strategies and clinical data encouraged us to review our acute stroke interventions in patient with anterior circulation tandem lesions to determine lesion patterns, interventional approaches, and angiographic or clinical outcomes.Patients and MethodsWe retrospectively analyzed a series of 39 consecutive patients with intracranial vessel occlusion of the anterior circulation simultaneously presenting with high-grade cervical internal carotid artery (ICA) stenosis or occlusion.ResultsEmergency ICA stent implantation was technically feasible in all patients, and intracranial recanalization with TICI ≥ 2b was reached in a large number of patients (64 %). Good clinical outcomes (mRS ≤ 2 at 3 months) were achieved in one third of the patients (36 %). Symptomatic hemorrhages occurred in four patients (10 %). Mortality was 10 %.ConclusionEndovascular recanalization of acute cervical carotid artery occlusion was technically feasible in all patients, and resulted in high extra- and intracranial revascularization rates. A trend for favorable clinical outcome was seen in a higher TICI score, younger age, good collateral status, and combined IV rTPA and endovascular therapy

Full Text Available Sexual assault is both a common and a very serious crime which is investigated by the police with an intensity second only to that of murder. Despite India stiffening its laws on sexual crimes, nothing much has changed on the ground. This retrospective study was conducted on 86 cases of sexual assault received for examination at Vijayanagara Institute of medical sciences (VIMS, Ballari, Karnataka, during the year 2010 - 2013. This study revealed that most vulnerable age group were males aged 11-20 years, where most commonly sexual crimes were performed by the person familiar to the victim (33.72%.  The maximum numbers of victims were medico-legally examined on the second day (46.51% of the assault. Examinations as recent tear of hymen was noticed in 16.66% female victims, and restrain marks on the victims were present in 25 (29.06% cases. The study aims to enhance public awareness regarding sexual violence, as support the ground to the law enforcement authorities to implement strategies to prevent such cases in the future. Keywords: Forensic science; forensic pathology; sexual assault; hymen; anal intercourse.

The primary objective of the phase I/II dose escalation studies was to evaluate the safety of the boronophenylalanine-fructose (BPA-F) mediated boron neutron capture therapy (BNCT) in subjects with glioblastoma multiforme (GBM). A secondary objective was to retrospectively assess the palliation of GBM by BNCT. Fifty-three subjects with GBM were treated under multiple dose escalation protocols at the Brookhaven Medical Research Reactor (BMRR). Twenty-six subjects were treated using one field, 17 subjects were treated using 2 fields and 10 subjects were treated using 3 fields. BPA-F related toxicity was not observed. The maximum radiation dose to a volume of approximately 1 cc of the normal brain varied from 8.9 to 15.9 gray-equivalent (Gy-Eq). The volume-weighted average radiation dose to normal brain varied from 1.9 to 9.5 Gy-Eq. Six RTOG (Radiation Therapy Oncology Group) grade 3 or 4 toxicities were attributed to BNCT. Four of the 53 subjects are still alive with 3 of them free of recurrent disease with over two years follow-up. The median times to progression and median survival time from diagnosis were 28.4 weeks and 12.8 months respectively. (author)

Cement burns: retrospective study of 18 cases and review of the literature.

Cement is increasingly used in the construction industry, but the occurrence of cement burns is rarely reported. This retrospective study concerns patients treated for cement burns in our unit between 1997 and 2002. Eighteen patients 18-64 years of age, treated previously in our unit for cement burns, were interviewed by telephone for evaluation. The mean time since treatment was 39 months. Burns were predominantly seen on the lower limbs, and a third occurred during an accident on the job. All deep burns were excised, and 16 patients received grafts. Mean hospital stay was 10 days, and mean sick leave 2 months. Our study indicated that all patients were poorly informed about cement-related risks. Surgical treatment of full-thickness cement burns at diagnosis enables rapid healing with a minimum of sequelae and reduces the high socioeconomic costs resulting from these lesions. This study indicates once again the need to improve preventive measures; which are very often inadequate because of lack of awareness of risks.

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. Median age was 69 (range, 33–90 years. Median gross tumor volume was 12.3 (8.6–21.3 cm3 and planning target volume 17.9 (12–27 cm3. Single fraction was used in 90 (30.9% and multifraction in 201 (69.1% lesions. At a median follow-up of 17.3 months (IQR 10.1–29.3 months, the median survival for the entire cohort 17.8 months with a 2-year OS of 35.3%.

Behavioral research has shown that spatial cues that orient attention toward task relevant items being maintained in visual short-term memory (VSTM) enhance item memory accuracy. However, it is unknown if these retrospective attentional cues ("retro-cues") enhance memory beyond typical short-term memory delays. It is also unknown whether retro-cues affect the spatial information associated with VSTM representations. Emerging evidence suggests that processes that affect short-term memory maintenance may also affect long-term memory (LTM) but little work has investigated the role of attention in LTM. In the current event-related potential (ERP) study, we investigated the duration of retrospective attention effects and the impact of retrospective attention manipulations on VSTM representations. Results revealed that retro-cueing improved both VSTM and LTM memory accuracy and that posterior maximal ERPs observed during VSTM maintenance predicted subsequent LTM performance. N2pc ERPs associated with attentional selection were attenuated by retro-cueing suggesting that retrospective attention may disrupt maintenance of spatial configural information in VSTM. Collectively, these findings suggest that retrospective attention can alter the structure of memory representations, which impacts memory performance beyond short-term memory delays.

Mesterházy, D.; Osvay, M.; Kovács, A.; Kelemen, A.

2012-01-01

Retrospective dosimetry is one of the most important tools of accidental dosimetry for dose estimation when dose measurement was not planned. In the affected area many objects can be applied as natural dosimeters. The paper discusses our recent investigations on various electronic components and common salt (NaCl) having useful thermoluminescence (TL) properties. Among materials investigated the electronic components of cell phones seem promising for retrospective dosimetry purposes, having high TL responses, proper glow curve peaks and the intensity of TL peaks vs. gamma dose received provided nearly linear response in the dose range of 10 mGy–1.5 Gy. - Highlights: ► Electronic components and common salt were investigated for accidental and retrospective dosimetry. ► SMD resistors seem promising for retrospective dosimetry purposes. ► Table salt can be used effectively for accidental dosimetry purposes, as well.

The Future Orientation of Past Memory: The Role of BA 10 in Prospective and Retrospective Retrieval Modes.

Klein made the provocative suggestion that the purpose of human episodic memory is to enable individuals to plan and prepare for the future. In other words, although episodic (retrospective) memory is about the past, it is not actually for the past; it is for the future. Within this focus, a natural subject for investigation is prospective memory, or memory to do things in the future. An important theoretical construct in the fields of both retrospective memory and prospective memory is that of a retrieval mode, or a neurocognitive set or readiness to treat environmental stimuli as potential retrieval cues. This construct was originally introduced in a theory of episodic (retrospective) memory and has more recently been invoked in a theory of how some prospective memory tasks are accomplished. To our knowledge, this construct has not been explicitly compared between the two literatures, and thus this is the purpose of the present article. Although we address the behavioral evidence for each construct, our primary goal is to assess the extent to which each retrieval mode appears to rely on a common neural region. Our review highlights the fact that a particular area of prefrontal cortex (BA 10) appears to play an important role in both retrospective and prospective retrieval modes. We suggest, based on this evidence and these ideas, that prospective memory research could profit from more active exploration of the relevance of theoretical constructs from the retrospective memory literature.

A xenogeneic DNA vaccination has been licensed for use in dogs with locally controlled stage II and III oral malignant melanoma (OMM). At present, there are limited outcome data for dogs with OMM treated with surgery and immunotherapy. The aim of this study is to retrospectively review the outcome and survival of 32 dogs affected by OMM that were treated with a combination of surgery and the xenogeneic DNA vaccination (with the addition of radiotherapy in some cases) and to determine the influence of surgical margins and delay in receiving vaccination. The overall median survival time (MST) was 335 days (95% CI: 301-540 days), and the overall median progression-free survival (PFS) was 160 days (mean 182 days, 95% CI: 132-232 days). Stage, completeness of surgical margins and delay in administration of the vaccine did not appear to statistically influence survival or PFS, although these results may reflect the low statistical power of the study due to small numbers. Further studies are required to assess whether the addition of any adjuvant treatment to surgery, including immunotherapy, is able to significantly prolong survival in cases of canine oral melanoma.

Patients with advanced illnesses show the highest prevalence for pressure injuries. In the palliative care setting, the ultimate goal is injury healing, but equally important is wound maintenance, wound palliation (wound-related pain and symptom management), and primary and secondary wound prevention. To describe the course of healing for pressure injuries in a home palliative care setting according to different end-points, and to explore patient and caregiver characteristics and specific care activities associated with their achievement. Four-year retrospective chart review of 669 patients cared for in a home palliative care service, of those 124 patients (18.5%) had at least one pressure injury with a survival rate less than or equal to six months. The proportion of healed pressure injuries was 24.4%. Of the injuries not healed, 34.0% were in a maintenance phase, whereas 63.6% were in a process of deterioration. Body mass index (P = 0.0014), artificial nutrition (P = 0.002), and age pay attention to artificial nutrition, continuous deep sedation, and the caregiver's role and gender.

Hilliard, Tracy M; Boulton, Matthew L

2012-05-01

The Robert Wood Johnson Foundation commissioned a systematic review of public health workforce literature in fall 2010. This paper reviews public health workforce articles published from 1985 to 2010 that support development of a public health workforce research agenda, and address four public health workforce research themes: (1) diversity; (2) recruitment, retention, separation, and retirement; (3) education, training, and credentialing; and (4) pay, promotion, performance, and job satisfaction. PubMed, ERIC, and Web of Science databases were used to search for articles; Google search engine was used to identify gray literature. The study used the following inclusion criteria: (1) articles written in English published in the U.S.; (2) the main theme(s) of the article relate to at least one of the four public health workforce research themes; and (3) the document focuses on the domestic public health workforce. The literature suggests that the U.S. public health workforce is facing several urgent priorities that should be addressed, including: (1) developing an ethnically/racially diverse membership to meet the needs of an increasingly diverse nation; (2) recruiting and retaining highly trained, well-prepared employees, and succession planning to replace retirees; (3) building public health workforce infrastructure while also confronting a major shortage in the public health workforce, through increased education, training, and credentialing; and (4) ensuring competitive salaries, opportunities for career advancement, standards for workplace performance, and fostering organizational cultures which generate high levels of job satisfaction for effective delivery of services. Additional research is needed in all four thematic areas reviewed to develop well-informed, evidence-based strategies for effectively addressing critical issues facing the public health workforce.

Mucosal lichen planus (MLP) is a therapeutic challenge in need of a new treatment approach because of its debilitating effect on patient's quality of life. We sought to evaluate a standardized treatment plan for patients with MLP. A second objective was to describe the effect of mycophenolate mofetil in this patient population. The study retrospectively analyzed 53 patients with MLP treated using a standardized algorithm. The number of MLP lesions, disease activity, and pain at the last visit were compared with baseline scores determined at the initial visit. Results were analyzed using the paired samples t test and confirmed with the Wilcoxon matched pairs signed rank test. The average number of lesions was reduced from 3.77 to 1.67 (P < .001). The average disease activity was reduced from 2.73 to 0.90 (P < .001). Average pain reported decreased from 2.03 to 1.03 (P < .001). This study was a retrospective analysis of a small patient population. There was no universal symptom severity scale used at the time of treatment for some patients. The standardized treatment plan reduced symptoms for patients with MLP. Mycophenolate mofetil appears to be a reasonable treatment option for these patients.

Acromioclavicular joint dislocations are common shoulder girdle injuries. The treatment of grade III acromioclavicular joint dislocations is controversial. Furthermore, the literature on the use of the Sur-giligTM synthetic ligament for reconstruction of dislocations is sparse. This retrospective review aimed to establish whether operative treatment was superior to non-operative treatment in grade III acromioclavicular joint dislocations treated at our institute over a 5-year period. We also reviewed the effectiveness of reconstruction with SurgiligTM after acute and chronic dislocations across all grades of acromioclavicular joint dislocations. Twenty-five patients completed full follow-up with grade III dislocations. The mean follow-up in the operated group was 3.56 years and in the non-operated group this was 3.29 years. The mean Oxford Shoul-der Score (OSS) in the operated group was 39.8, whereas the mean OSS in the non-operated group was 45.9 (p=0.01). The mean pain score in the operated group was 2.2, and in the non-operated group this was 1.6. The mean satisfaction score in the operated group was 8.2 and that in the non-operated group was 7.8. There was no statistically significant difference in pain or satisfaction scores. In respect to the cohort treated with Surg-iligTM synthetic ligament, 22 patients across all grades of dislocations had this procedure performed. The mean post-operative Oxford Shoulder Score (OSS) was 40. 1. Non-operative treatment is not inferior to operative treatment for grade III acromioclavicular joint dislocations. The data from this study demonstrat-ed that the non-operated group had superior Ox-ford Shoul-der Scores that were statistically significant. 2. Additionally, the use of the SurgiligTM ligament appears to be effective in treating both chronic and acute acromioclavicular joint dislocations.

Retrospective records review. WhMD passengers traveling on LATVs while remaining seated in their. Adverse incidents characterized based on vehicle motion, WhMD activity during incident, and incident scenario. Injury characterized based on outcome, medical attention sought, vehicle activity, WhMD activity and incident scenario. 115 WhMD-related incident reports for years 2000-2005 were analyzed. Most incidents occurred when the LATV was stopped (73.9%), during ingress/egress (42.6%), and at the securement station (33.9%) when the LATV was moving. The combination of WhMD tipping and passenger falling (43.4%) occurred most frequently, and was 1.8 times more likely to occur during ingress/egress than at the securement station. One-third (33.6%) of all incidents resulted in injury, and injuries were equally distributed between ingress/egress (43.6%) and at the securement station (43.6%). WhMD users have a greater chance of incurring injury during ingress/egress than during transit. Research is needed to objectively assess real world transportation experiences of WhMD passengers, and to assess the adequacy of existing federal legislation/guidelines for accessible ramps used in public transportation.

The anaesthetic challenge of awake craniotomy is to maintain adequate sedation, analgesia, respiratory and haemodynamic stability in an awake patient who should be able to co-operate during intraoperative neurological assessment. The current literature, sharing the experience on awake craniotomy, in Indian context, is minimal. Hence, we carried out a retrospective study with the aim to review and analyse the anaesthetic management and perioperative complications in patients undergoing awake craniotomy, at our centre. Medical records of 54 patients who underwent awake craniotomy for intracranial lesions over a period of 10 years were reviewed, retrospectively. Data regarding anaesthetic management, intraoperative complications and post-operative course were recorded. Propofol (81.5%) and dexmedetomidine (18.5%) were the main agents used for providing conscious sedation to facilitate awake craniotomy. Hypertension (16.7%) was the most commonly encountered complication during intraoperative period, followed by seizures (9.3%), desaturation (7.4%), tight brain (7.4%), and shivering (5.6%). The procedure had to be converted to general anaesthesia in one of patients owing to refractory brain bulge. The incidence of respiratory and haemodynamic complications were comparable in the both groups (P > 0.05). There was less incidence of intraoperative seizures in patients who received propofol (P = 0.03). In post-operative period, 20% of patients developed new motor deficit. Mean intensive care unit stay was 2.8 ± 1.9 day (1-14 days) and mean hospital stay was 7.0 ± 5.0 day (3-30 days). 'Conscious sedation' was the technique of choice for awake craniotomy, at our institute. Fentanyl, propofol, and dexmedetomidine were the main agents used for this purpose. Patients receiving propofol had less incidence of intraoperative seizure. Appropriate selection of patients, understanding the procedure of surgery, and judicious use of sedatives or anaesthetic agents are key to the

Technological advances have led to innovative insulin delivery systems for patients with type 1 diabetes mellitus. In particular, the combination of miniature engineering and software algorithms contained in continuous subcutaneous insulin infusion (CSII) system pumps provide the user and the healthcare practitioner with an opportunity to review and adjust blood glucose (BG) levels according to system feedback, and to modify or programme their regimen according to their needs. While CSII pumps record a number of data parameters such as BG level, carbohydrate intake, activity and insulin delivered, these data are generally 'locked in' and can only be accessed by uploading to a cloud-based system, thus information is not contemporaneous. The Cellnovo Diabetes Management System (Cellnovo, Bridgend, UK) allows data to be transmitted securely and wirelessly in real time to a secure server, which is then retrieved by an online platform, the Cellnovo Online platform, enabling continuous access by the user and by clinicians. In this article, the authors describe a retrospective review of the patient data automatically uploaded to the Cellnovo Online platform. Baseline clinical and demographic characteristics collected at the start of pump therapy are shown for all patients, and BG data from a sub-cohort of patients who have been using the system for at least 6 months and who take and record an average of three BG level tests per day are presented to demonstrate glycaemic data over time.

Pancreatectomies have been identified as procedures with an increased risk of readmission. In surgical patients, readmissions within 30 days of discharge are usually procedure-related. We sought to determine predictors of 30-day readmission following pancreatic resections in a large healthcare system. We retrospectively collected information from the records of 383 patients who underwent pancreatic resections from 2004-2013. To find the predictors of readmission in the 30 days after discharge, we performed a univariate screen of possible variables using the Fisher's exact test for categorical variables and the Mann-Whitney U test for continuous variables. Multivariate analysis was used to determine the independent factors. Fifty-eight (15.1%) patients were readmitted within 30 days of discharge. Of the patients readmitted, the most common diagnoses at readmission were sepsis (17.2%), and dehydration (8.6%). Multivariate logistic regression found that the development of intra-abdominal fluid collections (OR = 5.32, P readmission within 30 days of discharge. Our data demonstrate that factors predictive of 30-day readmission are a combination of patient characteristics and the development of post-operative complications. Targeted interventions may be used to reduce the risk of readmission. Copyright © 2018. Published by Elsevier B.V.

Since the beginning of the 1990s the exploration of optically stimulated luminescence in retrospective accident dosimetry has driven an intensive investigation and development programme at Ris deg. into measurement facilities and techniques. This paper reviews some of the outcomes of this programme, including the evaluation of the single-aliquot regenerative-dose measurement protocol with brick quartz and the determination of dose-depth profiles in building materials as a guide to determining the mean energy of the incident radiation. Investigations into heated materials are most advanced, and a lower detection limit for quartz extracted from Chernobyl bricks was determined to be <10 mGy. The first results from the measurement of doses in unheated building materials such as mortar and concrete are also discussed. Both small-aliquot and single-grain techniques have been used to assess accident doses in these cement based building materials more commonly found in workplaces. Finally some results of a preliminary investigation of the OSL properties of household chemicals are discussed with reference to their potential as accident dosemeters. (author)

Despite the introduction of universal newborn hearing screening (UNHS), unilateral hearing loss (UHL) is sometimes recognized late. This diagnostic delay has adverse repercussions, given the importance of binaural hearing for the development of normal auditory processing. It is incorrect to maintain that unilateral hearing is the minimum requirement for adequate speech development and that hearing aid provision is consequently unnecessary. In our retrospective study, hearing aid provision resulted in improved directional and selective hearing (quiet and noisy environments) and, compared with their chronically ill counterparts, the children in our study displayed superior health-related quality of life (HRQoL) scores in all areas. On the basis of the results, the authors conclude that even mild hearing losses (from an auditory threshold of 30 to 40 dB) should have the opportunity for hearing aid provision. A selective literature review was conducted in PubMed and textbooks and with reference to national and international guidelines. Early diagnosis and treatment of UHL have a positive effect on verbal-cognitive, linguistic, communicative, and socio-emotional development, as demonstrated by neurophysiological studies. Among the treatment modalities with differing effects on the quality of binaural hearing, cochlear implants are now used increasingly in children with hearing loss bordering on deafness. Published evidence and clinical experience support early diagnosis and treatment. Wherever feasible, hearing aid provision before or at the end of the first year of life is recommended for children with UHL. What is Known: • Almost 30 years ago, poor academic performance was reported in children with unilateral hearing loss (UHL). • Despite improvements in treatment options, it is traditionally held that unilateral hearing is the minimum requirement for adequate speech development and hearing aid provision is unnecessary. What is New: • Academic and behavioral

Industrial radiography is known to be one of the most vulnerable lines of work among the range of different radiation work. According to the relevant law in Korea, every worker registered in this work should check their blood cell counts every year in addition to their thermoluminescent dosimeter (TLD) doses. Cytogenetic dosimetry has been employed for several decades as a method for estimating the dose of ionizing radiation (IR) received by an individual. In cases of recent acute exposure, the most reliable method is to score dicentric chromosomes in solid-stained metaphase cells. Dicentric aberrations are unstable because their frequency decrease with time after IR exposure. The purpose of the present study was to review the effectiveness of the current regulation that requires all registered radiation workers to check their blood counts every year in order to screen for exposed workers. In addition, the clinical usefulness of cytogenetic dosimetry as a retrospective tool for dose estimation has been evaluated. From this study, we hope to make practical recommendations for improving the current radiation protection regulation. We ascertain that reviewing consecutive results of blood cell counts and retrospective biodosimetry are useful complementary tools to TLD doses for health protection regulation. Several confounding factors including work duration and previous medical history need to be considered for the interpretation of cytogenetic dosimetry results.

Research Review: Evaluating and reformulating the developmental taxonomic theory of antisocial behaviour

Science.gov (United States)

Fairchild, Graeme; Goozen, Stephanie HM; Calder, Andrew J; Goodyer, Ian M

2013-01-01

BackgroundThe developmental taxonomic theory proposes that there are two subtypes of antisocial behaviour. The first is a neurodevelopmental disorder which emerges in early childhood and follows a life-course persistent course, whereas the second emerges in adolescence, remits in early adulthood and reflects peer processes such as mimicry of antisocial peers. The aim of this review was to evaluate the developmental taxonomic theory in the light of recent empirical research. MethodsWe conducted a comprehensive literature review comparing these subtypes of antisocial behaviour based on searches on PubMed and other scientific databases covering the period from 1993 to 2013. We focused on research encompassing psychiatric epidemiology, personality assessment, neuropsychology, neuroendocrinology, genetics, and structural and functional neuroimaging. Sixty one empirical studies were identified that investigated one of these forms of antisocial behaviour separately or explicitly compared childhood-onset and adolescence-onset forms of antisocial behaviour. ResultsEmpirical research provides support for the hypothesis that life-course persistent antisocial behaviour is a neurodevelopmental disorder which emerges in the transactions between individual vulnerabilities and environmental adversity. In contrast to the developmental taxonomic theory, however, empirical findings suggest that severe antisocial behaviour that emerges in adolescence frequently has a negative prognosis and is rarely limited to the adolescent period. In addition, both forms of antisocial behaviour are associated with emotion processing deficits, changes in brain structure and function, alterations in cortisol secretion, and atypical personality traits (such as increased callous-unemotional traits). ConclusionsWe conclude that the developmental taxonomic theory is in need of revision, as differences between life-course persistent and adolescence-onset forms of antisocial behaviour appear to be

We present a retrospective study of 25 patients with spontaneous pneumothorax (three recurrent) comprising 16 Saudis (nine males and seven females) and eight non-Saudi's (eight males and one female), seen at the Asir Central Hospital, Abha, over a period of 45 months. Almost one-third of patients (9/25) had no underlying cause discernible by our investigational facilities (chest x-ray, ultrasonography, computed tomographic scan and flexible bronchofiberscopy). Underlying pneumonia (three patients), pulmonary tuberculosis (two patients), lung abscess (one patient) and congenital bullae (one patient) constituted the etiology in another third of the spontaneous pneumothorax patients. Other underlying pulmonary diseases, precipitating spontaneous pneumothorax in the group included pulmonary fibrosis, metastatic mesothelioma and immunosuppression in a medulloblastoma patient undergoing chemotherapy with the development of chickenpox. Closed thoracostomy tube drainage was the only method of treatment in 20 out of 25 patients, with three failures of closed thoracostomy tube drainage needing thoractomy and resection of blebs/bullae. The only complication was empyema in two of the patients. Two patients were successfully treated conservatively with observation alone. (author)

Use of electron paramagnetic resonance dosimetry with tooth enamel for retrospective dose assessment. Report of a co-ordinated research project

2002-12-01

Electron paramagnetic resonance (EPR) dosimetry is a physical method for the assessment of absorbed dose from ionising radiation. It is based on the measurement of stable radiation induced radicals in human calcified tissues (primarily in tooth enamel). EPR dosimetry with teeth is now firmly established in retrospective dosimetry. It is a powerful method for providing information on exposure to ionising radiation many years after the event, since the 'signal' is 'stored' in the tooth or the bone. This technique is of particular relevance to relatively low dose exposures or when the results of conventional dosimetry are not available (e.g. in accidental circumstances). The use of EPR dosimetry, as an essential tool for retrospective assessment of radiation exposure is an important part of radioepidemiological studies and also provides data to select appropriate countermeasures based on retrospective evaluation of individual doses. Despite well established regulations and protocols for maintaining radiation protection dose limits, the assurance that these limits will not be exceeded cannot be guaranteed, thus providing new challenges for development of accurate methods of individual dose assessment. To meet some of these challenges, in 1998 the IAEA initiated a co-ordinated research project (CRP) with the objective to review the available methods, current research and development in EPR biodosimetry technology, which may be of practical use. The major goal of this CRP was to investigate the use of EPR biodosimetry for reconstruction of absorbed dose in tooth enamel with the aim of providing Member States with up-to-date, and generally agreed upon advice regarding the most suitable procedures and the best focus for their research. The co-ordinated research project was conducted over four years and this publication presents the results and findings by a group of investigators from different countries.

Musculoskeletal allografts are now commonly used. To decrease the potential risks of transmission of pathogenic bacteria, fungi, or viruses to the transplant recipients, certain issues regarding the management of patients who receive contaminated allografts need to be addressed. We aimed to clarify the incidence and extent of disease transmission from allografts by analyzing the allografting procedures performed in the bone bank of our hospital over the past 20 years. We retrospectively reviewed the data from our allograft registry center on 3979 allografts that were implanted in 3193 recipients throughout a period of two decades, from July 1991 to June 2011. The source of the allografts, results of all screening tests, dates of harvesting and implantation, and recipients of all allografts were checked. With the help of the Center for Infection Control of our hospital, a strict prospective, hospital-wide, on-site surveillance was conducted, and every patient with healthcare-associated infection was identified. Fisher's exact test was used to compare the infection rate between recipients with sterile allografts and those with contaminated allografts. The overall discard and infection rates were, respectively, 23% and 1.3% in the first decade (1991-2001); and 18.4% and 1.25% in the second decade (2001-2011). The infection rate of contaminated allograft recipients was significantly higher than that of sterile allograft recipients (10% vs. 1.15%, P bank are comparable with those of international bone banks. Strict allograft processing and adequate prophylactic use of antibiotics are critical to prevent infection and disease transmission in such cases.

To examine the surgical indications and pathologic findings in patients undergoing a second surgery after placement of the Essure permanent birth control system to determine the role of Essure in developing new-onset pelvic pain. Retrospective cohort (Canadian Task Force classification II-2). Tertiary-level hospital. Women who have had Essure placement and subsequent second surgery. Charts from women undergoing pelvic surgery after Essure placement from June 2002 to June 2013 were reviewed and the indication for the procedure, surgical and pathologic findings noted. Of 1430 patients, 62 (4.3%) had a second surgery after Essure placement, and 24 of these (1.6%) had a surgical indication not related to pain. The remaining 38 patients (2.7%) had either new-onset (n = 27) or worsening pre-existing pain (n = 11). In the new-onset pain group, 15 (1%) had surgical findings or pathology consistent with a painful gynecologic condition. In the remaining 12, 8 (0.5%) seemed to be related to some perforation or migration of the Essure device. In 4 patients (0.3%) with no other obvious cause for the new-onset pain, it was thus attributed to the Essure microinsert. Essure sterilization can be associated with new-onset pain or a worsening of a pre-existing painful gynecologic condition, although both are very rare. A careful and complete consent before placement and a thorough examination if pain does occur usually show some etiology for the pain other than the Essure insert. Copyright © 2016 AAGL.

Objective: To determine the incidence proportion of surgical site infection following hernia repair in a daycare setting at a tertiary care hospital of a low-income country. Methods: The retrospective audit was done at the Aga Khan University Hospital, Karachi, from June 1, 2008 to May 30, 2009. Patients with age >15 years who underwent Lichenstein's open mesh repair in daycare were included. Surgical Site Infection was labelled if the records revealed any of the following: opening of the wound by the primary surgeon; pain, tenderness and raised temperature of skin; purulent discharge from the wound; if the surgeon had documented it as a surgical site infection. SPSS 16 was used for data analysis. Results: After reviewing the retrieved files, 104 patients were found eligible. Of them, 102 (98%) were males. Overall wound-related complications were found in 13 (12.5%), whereas surgical site infection was found in 8 (7.7%) patients. The mean age of those with infections was 38.7+-18 year, while that of those with no surgical site infection was 47.8+-18 years. Smoking was found significantly associated with surgical site infection with 5.8 times higher incidence as compared to the non-smokers (OR with 95% CI: 5.6 (1.2, 25.3)). Conclusions: The incidence of surgical site infection after hernia repair with mesh in a daycare setting at a tertiary care hospital of a low-income country was higher than internationally reported incidence. Smoking was found to be a significant risk factor. (author)

The numerous cohort of Chernobyl liquidators is a very attractive subject for epidemiological follow up due to high levels of exposure, age-gender distribution and availability of patients for medical examination. However, dosimetric information related to this population is incomplete, in many cases the quality of available dose records is doubtful and uncertainties of all dose values are not determined. Naive attempts to evaluate average doses on the basis of such factors as 'distance from the reactor' obviously fail due to large variation of tasks and workplace contamination. Therefore, prior to any sensible consideration of liquidators as a subject of epidemiological study, their doses should be evaluated (reevaluated) using the methods of retrospective dosimetry. Retrospective dosimetry in general got significant development over the last decade. However, most of the retrospective dosimetry techniques are time consuming, expensive and possess sensitivity threshold. Therefore, application of retrospective dosimetry for the needs of epidemiological follow up studies requires development of certain strategy. This strategy depends, of coarse, on the epidemiological design of the study, availability of resources and dosimetric information related to the time of clean up. One of the strategies of application of retrospective dosimetry may be demonstrated on the example of a cohort study with occasional nested case control consideration. In this case, the tools are needed for validation of existing dose records (of not always known quality), screening of the study cohort with express dosimetric method called to determine possible dose ranges, and 'state-of-the-art' assessment of individual doses for selected subjects (cases and controls). Verification of dose records involves analysis of the statistical regularities of dose distributions and detection of possible extraneous admixtures (presumably falsified dose records).

Suspected victims of child abuse who were Results Forty-seven children had a negative initial skeletal survey and were included for analysis. The mean age was 6.9 months (SD 5.7; the mean number of days between skeletal surveys was 18.7 (SD 10.1 Four children (8.5% had signs of healing bone trauma on a follow-up skeletal survey. Three of these children (75% had healing rib fractures and one child had a healing proximal humerus fracture. The findings on the follow-up skeletal survey yielded forensically important information in all 4 cases and strengthened the diagnosis of non-accidental trauma. Conclusion 8.5 percent of children with negative initial skeletal surveys had forensically important findings on follow-up skeletal survey that increased the certainty of the diagnosis of non-accidental trauma. A follow-up skeletal survey can be useful even when the initial skeletal survey is negative.

The 2005 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines for hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and health care-associated pneumonia (HCAP) stress the importance of initiating prompt appropriate empiric antibiotic therapy. This study's purpose was to determine the percentage of patients with HAP, VAP, and HCAP who received guideline-based empiric antibiotic therapy and to determine the average time to receipt of an appropriate empiric regimen. A retrospective chart review of adults with HAP, VAP, or HCAP was conducted at a community hospital in suburban Birmingham, Alabama. The hospital's electronic medical record system utilized International Classification of Diseases, Ninth Revision (ICD-9) codes to identify patients diagnosed with pneumonia. The percentage of patients who received guideline-based empiric antibiotic therapy was calculated. The mean time from suspected diagnosis of pneumonia to initial administration of the final antibiotic within the empiric regimen was calculated for patients who received guideline-based therapy. Ninety-three patients met the inclusion criteria. The overall guideline adherence rate for empiric antibiotic therapy was 31.2%. The mean time to guideline-based therapy in hours:minutes was 7:47 for HAP and 28:16 for HCAP. For HAP and HCAP combined, the mean time to appropriate therapy was 21:55. Guideline adherence rates were lower and time to appropriate empiric therapy was greater for patients with HCAP compared to patients with HAP. © The Author(s) 2015.

Laser resurfacing in patients with Fitzpatrick skin phototypes (SPT) IV to VI is associated with a higher risk of pigmentary alteration. There is a paucity of studies evaluating optimum treatment parameters for fractional lasers in darkly pigmented skin types. This is a retrospective review of medical records for patients with SPT IV to VI who were treated with a 1,550 nm erbium-doped fractional nonablative laser (Fraxel Re:Store SR 1550; Solta Medical, Hayword, CA). Data were collected from patient charts and the clinic laser logbook from January 2008 to January 2012. The frequency of treatment-associated postinflammatory hyperpigmentation (PIH) and treatment settings used were evaluated. A total of 115 total laser sessions (45 patients) were included in our analysis. Five of the sessions (4%) were accompanied by PIH, 2 of which occurred in a single patient. Only 1 episode of PIH lasted longer than 1 month (2 months). Two of the 5 cases had only transient PIH (≤7 days), one of which was reported by the patient and not clinically evident on examination. The 1,550 nm erbium-doped fractional laser is well tolerated in SPT IV to VI. Fractional laser resurfacing, with the settings used and pretreatment and posttreatment hydroquinone 4% cream, was associated with a low risk of PIH in darker skin types.

The current retrospective chart review compared glycemic control and cost impact of two insulin administration systems, V-Go ® versus usual care with standard of care (SOC) insulin injections, in eight patients residing in a nursing home (NH). A total of 1,937 blood glucose (BG) values were collected over 61 days. Significant improvements were observed for the V-Go versus SOC group in time in range 100 mg/dL to 200 mg/dL (V-Go 59.09% vs. SOC 34.02%; p < 0.001), reduced BG fluctuations as measured by standard deviation (V-Go 61.2 vs. SOC 92.1; p < 0.001), and improved mean daily BG (V-Go 159.38 mg/dL vs. SOC 223.86 mg/dL; p < 0.001). The estimated A1c change, calculated from BG values, decreased from 8.9% to 7.2% in the V-Go group and increased from 9.0% to 9.4% in the SOC group. Compared to SOC, use of V-Go decreased the mean time for insulin administration by nursing staff by 26.3 minutes per patient per day and associated labor costs by $328.75 per patient per month. Insulin administration with V-Go may improve glycemic control and reduce administration costs compared to existing care in the NH setting. [Journal of Gerontological Nursing, 43(1), 10-16.].

2013-11-14

Cine cardiovascular magnetic resonance (CMR) is challenging in patients who cannot perform repeated breath holds. Real-time, free-breathing acquisition is an alternative, but image quality is typically inferior. There is a clinical need for techniques that achieve similar image quality to the segmented cine using a free breathing acquisition. Previously, high quality retrospectively gated cine images have been reconstructed from real-time acquisitions using parallel imaging and motion correction. These methods had limited clinical applicability due to lengthy acquisitions and volumetric measurements obtained with such methods have not previously been evaluated systematically. This study introduces a new retrospective reconstruction scheme for real-time cine imaging which aims to shorten the required acquisition. A real-time acquisition of 16-20s per acquired slice was inputted into a retrospective cine reconstruction algorithm, which employed non-rigid registration to remove respiratory motion and SPIRiT non-linear reconstruction with temporal regularization to fill in missing data. The algorithm was used to reconstruct cine loops with high spatial (1.3-1.8 × 1.8-2.1 mm²) and temporal resolution (retrospectively gated, 30 cardiac phases, temporal resolution 34.3 ± 9.1 ms). Validation was performed in 15 healthy volunteers using two different acquisition resolutions (256 × 144/192 × 128 matrix sizes). For each subject, 9 to 12 short axis and 3 long axis slices were imaged with both segmented and real-time acquisitions. The retrospectively reconstructed real-time cine images were compared to a traditional segmented breath-held acquisition in terms of image quality scores. Image quality scoring was performed by two experts using a scale between 1 and 5 (poor to good). For every subject, LAX and three SAX slices were selected and reviewed in the random order. The reviewers were blinded to the reconstruction approach and acquisition protocols and

PurposeTo evaluate the intermediate outcomes of temporary partially covered tracheobronchial stenting in patients with benign tracheobronchial stenosis.Materials and MethodsWe conducted a retrospective study of patients with benign tracheobronchial stenosis who underwent stent placement. All stents were removed approximately 3 months after placement. Respiratory function was assessed using the visual analogue scale (VAS) and Karnofsky performance status scale (KPS) before and after stent placement. The lumen diameters of the stenotic lesions were measured using chest computed tomography (CT) and compared between before stent placement and after stent removal.ResultsA total of 51 stents were successfully placed in consecutive 51 patients with benign tracheobronchial stenosis. No serious complications occurred. The mean VAS and KPS scores significantly improved after stent removal (6.291 ± 0.495 and 25.352 ± 10.533, respectively) compared with those before stent placement (1.493 ± 0.504 and 60.140 ± 16.344, respectively; P   0.05).ConclusionTemporary partially covered stenting may be a safe and effective treatment for benign tracheobronchial stenosis.

Mercier, Joey; Voutsadakis, Ioannis A

2017-11-01

Metastatic colorectal cancer is a common disease encountered in oncology practice and treatment options beyond fluoropyrimidines, irinotecan, oxaliplatin and monoclonal antibodies against epidermal growth factor receptor and vascular endothelium growth factor (VEGF) are limited. Regorafenib, a new drug that targets tyrosine kinases such as VEGF receptor as well as others, has been added recently to the armamentarium for metastatic colorectal cancer. This report analyzes the published experience with this drug in clinical practice outside of clinical trials. A literature search of major databases was performed for the identification of studies of regorafenib in metastatic colorectal cancer. Studies retained for further analysis were in English or French, describing 20 or more patients treated with regorafenib monotherapy and not part of a phase I, II or III trial. Results of the pooled analysis of retrospective studies were compared with results of the published phase III trials and a phase IIIb prospective study. Twelve publications including a total of 702 patients were included in the meta-analysis. Summary response rate was 2% [95% confidence interval (CI) =0.8-3.2%] and the disease control rate 38.14% (95% CI=32.35-43.93%). Summary survival rates were 3.34 months (95% CI=2.71-3.97 months) for progression-free and 7.27 months (95% CI=6.23-8.3 months) for overall survival. These were similar to the phase III and IIIb studies. Most common adverse effects were also consistent with those of the published phase III experience. This systematic review and meta-analysis confirmed a moderate efficacy of regorafenib in later-stage metastatic colorectal cancer in the everyday clinical practice setting outside of clinical trials. Future identification of biomarkers may aid in further tailoring of this treatment in order to obtain maximum clinical benefit.

Retrospective Review of Watershed Characteristics and a Framework for Future Research in the Sarasota Bay Watershed, Florida

Science.gov (United States)

Kish, George R.; Harrison, Arnell S.; Alderson, Mark

2008-01-01

The U.S. Geological Survey, in cooperation with the Sarasota Bay Estuary Program conducted a retrospective review of characteristics of the Sarasota Bay watershed in west-central Florida. This report describes watershed characteristics, surface- and ground-water processes, and the environmental setting of the Sarasota Bay watershed. Population growth during the last 50 years is transforming the Sarasota Bay watershed from rural and agriculture to urban and suburban. The transition has resulted in land-use changes that influence surface- and ground-water processes in the watershed. Increased impervious cover decreases recharge to ground water and increases overland runoff and the pollutants carried in the runoff. Soil compaction resulting from agriculture, construction, and recreation activities also decreases recharge to ground water. Conventional approaches to stormwater runoff have involved conveyances and large storage areas. Low-impact development approaches, designed to provide recharge near the precipitation point-of-contact, are being used increasingly in the watershed. Simple pollutant loading models applied to the Sarasota Bay watershed have focused on large-scale processes and pollutant loads determined from empirical values and mean event concentrations. Complex watershed models and more intensive data-collection programs can provide the level of information needed to quantify (1) the effects of lot-scale land practices on runoff, storage, and ground-water recharge, (2) dry and wet season flux of nutrients through atmospheric deposition, (3) changes in partitioning of water and contaminants as urbanization alters predevelopment rainfall-runoff relations, and (4) linkages between watershed models and lot-scale models to evaluate the effect of small-scale changes over the entire Sarasota Bay watershed. As urbanization in the Sarasota Bay watershed continues, focused research on water-resources issues can provide information needed by water

Full Text Available Objective: Knowledge concerning treatment and care of hand lesions is often based on small case series, case reports and a few large general case series. The aim of this study is to present our experience with hand tumors’ and tumor-like lesions’ incidence, age range and localizations. Material and Method: Between 2006-2016, 402 patients operated and histopathologically diagnosed with bone and soft tissue tumorous conditions of the hand were evaluated retrospectively. Results: Three hundred sixty one out of 402 cases (89.8% were soft tissue tumors and 41 cases (10.2% were osseous tumors of the hand. A total of 10 malignant tumors (2.5% were encountered in the hand. The average age of the patients was 41.9 years (ranged from 1 to 83 years. Among 361 soft tissue tumors, only 6 cases (1.6% were malignant and they were squamous cell tumors (n=5 and synovial sarcoma (n=1. The most common soft tissue pathology was ganglion cyst (n=125. The most common bone tumor was enchondroma, diagnosed in 26 patients (6.4% of all patients. Primary malignant bone tumors were extremely rare in the hand; one osteosarcoma and one chondrosarcoma were reported. Metastatic tumors to the hand were seen in two patients; and they were lung carcinoma and chondrosarcoma metastasis. Conclusion: Up-date knowledge and a thorough understanding of the nature and demographic characteristics of the tumorous conditions of the hand are crucial for accurate diagnosis and appropriate treatment.

2013-07-01

Spurious hyperkalaemia is a relatively common occurrence in samples originating from primary care. Failure to identify spurious hyperkalaemia carries a significant risk of patient mismanagement. We have carried out a retrospective evaluation to review the impact of the use of centrifuges in primary care for biochemistry blood samples on the management of hyperkalaemia. Serum potassium concentrations in samples received from primary care were reviewed for six months prior to and after the implementation of on-site centrifugation. Samples exhibiting significant hyperkalaemia (serum potassium >6.0 mmol/L) were further investigated to ascertain the degree of patient follow-up. There was a significant decrease in the number of samples exhibiting marked hyperkalaemia following the implementation (2244 versus 524; P centrifugation of serum samples in primary care improves the sample quality and the integrity of the potassium results reported. We have also demonstrated evidence of an improvement in patient management and quality of care.

Topical bimatoprost is a topical prostaglandin analog originally used to treat glaucoma and more recently used to cosmetically induce hypertrichosis of the eyelashes. Iris pigmentation change has been noted in the treatment of glaucoma but has not been assessed with the cosmetic periorbital application of bimatoprost. To evaluate for iris pigmentation change with the long-term cosmetic use of topical bimatoprost. A retrospective chart review in a cosmetic dermatology practice of women (N = 50) who consistently purchased topical bimatoprost over an average of 4.59 years was compared with that of age-matched non-bimatoprost patients (N = 50). A blinded evaluator assessed each patient for iris pigmentary change. No iris pigmentation change was noted with the cutaneous application of bimatoprost. The cutaneous application of bimatoprost appears to be safe with minimal risk for iris pigmentation change.

A retrospective analysis of medical record use in e-consultations.

Science.gov (United States)

Pecina, Jennifer L; North, Frederick

2017-06-01

Introduction Under certain circumstances, e-consultations can substitute for a face-to-face consultation. A basic requirement for a successful e-consultation is that the e-consultant has access to important medical history and exam findings along with laboratory and imaging results. Knowing just what information the specialist needs to complete an e-consultation is a major challenge. This paper examines differences between specialties in their need for past information from laboratory, imaging and clinical notes. Methods This is a retrospective study of patients who had an internal e-consultation performed at an academic medical centre. We reviewed a random sample of e-consultations that occurred in the first half of 2013 for the indication for the e-consultation and whether the e-consultant reviewed data in the medical record that was older than one year to perform the e-consultation. Results Out of 3008 total e-consultations we reviewed 360 (12%) randomly selected e-consultations from 12 specialties. Questions on management (35.8%), image results (27.2%) and laboratory results (25%) were the three most common indications for e-consultation. E-consultants reviewed medical records in existence more than one year prior to the e-consultation 146 (40.6%) of the time with e-consultants in the specialties of endocrinology, haematology and rheumatology, reviewing records older than one year more than half the time. Labs (20.3%), office notes (20%) and imaging (17.8%) were the types of medical data older than one year that were reviewed the most frequently overall. Discussion Management questions appear to be the most common reason for e-consultation. E-consultants frequently reviewed historical medical data that is older than one year at the time of the e-consultation, especially in endocrinology, haematology and rheumatology specialties. Practices engaging in e-consultations that require transfer of data may want to include longer time frames of historical information

To investigate the feasibility of applying prospectively ECG-triggered sequential coronary CT angiography (CCTA) to patients with atrial fibrillation (AF) and evaluate the image quality and radiation dose compared with a retrospectively ECG-gated helical protocol. 100 patients with persistent AF were enrolled. Fifty patients were randomly assigned to a prospective protocol and the other patients to a retrospective protocol using a second-generation dual-source CT (DS-CT). Image quality was evaluated using a four-point grading scale (1 = excellent, 2 = good, 3 = moderate, 4 = poor) by two reviewers on a per-segment basis. The coronary artery segments were considered non-diagnostic with a quality score of 4. The radiation dose was evaluated. Diagnostic segment rate in the prospective group was 99.4 % (642/646 segments), while that in the retrospective group was 96.5 % (604/626 segments) (P < 0.001). Effective dose was 4.29 {+-} 1.86 and 11.95 {+-} 5.34 mSv for each of the two protocols (P < 0.001), which was a 64 % reduction in the radiation dose for prospective sequential imaging compared with retrospective helical imaging. In AF patients, prospectively ECG-triggered sequential CCTA is feasible using second-generation DS-CT and can decrease >60 % radiation exposure compared with retrospectively ECG-gated helical imaging while improving diagnostic image quality.

Full Text Available BackgroundIn contrast to the diverticulosis of the colon jejunal diverticulosis is a rare condition. The incidence is 0.06% up to 5% in large autopsy series. Complicated diverticulosis jejuni (CDJ often presents with unspecific symptoms. Therefore diagnosis is often a challenging diagnosis and due to the clinical rarity no generally valid recommendation of perioperative management exists. Patients and MethodsWe considered only patients that were operated in our centre between April 2007 and August 2014. Patients were identified by data bank search via International Statistical Classification of Diseases and Related Health Problems (ICD diagnosis code K57.10. Data was manually screened and patients with Meckel’s and duodenal diverticula were excluded from this study. Eleven consecutive patients with CDJ were finally included in this study. We analysed symptoms, diagnostic procedures, surgical treatment and postoperative morbidity and mortality. ResultsThe median age of our patients was 76 years (range 34 87. CDJ presented most frequently as intestinal bleeding or as diverticulitis. Clinical symptoms were unspecific abdominal pain, hematemesis or melena, ileus, nausea and emesis as well as patients with acute abdomen. Esophagogastroduodenoscopies confirmed CDJ in two of three patients. An abdominal CT-scan only helped to diagnose CDJ in two of ten patients. Eight (72.7% patients received an open segmental resection with primary anastomosis. In three (27.3% cases a reoperation was necessary. Overall morbidity rate was 45.5% and perioperative mortality was 9.1%. Conclusions Due to the acute character of the disease patients with CDJ are seriously ill. To diagnose patients with CDJ remains challenging as diagnostic investigations are usually not helpful in confirming diagnosis. Still, diagnosis of CDJ is most frequently confirmed intraoperatively.Keywords: complicated jejunal diverticulitis, perioperative management, acute abdomen, visceral surgery

Women in Scotland with uncomplicated pregnancies are encouraged by professional bodies and national guidelines to access community based models of midwife-led care for their labour and birth. The evidence base for these guidelines relates to comparisons of predominantly urban birth settings in England. There appears to be little evidence available about the quality of the care during the antenatal, birth and post birth periods available for women within the Scottish Community Maternity Unit (CMU) model. The research aim was to explore the safety and effectiveness of the maternity services provided at two rural Community Maternity Units in Scotland, both 40 miles by main road access from a tertiary obstetric unit. Following appropriate NHS and University ethical approval, an anonymous retrospective review of consecutive maternity records for all women who accessed care at the CMUs over a 12 month period (June 2011 to May 2012) was undertaken in 2013 -14. Data was extracted using variables chosen to provide a description of the socio-demographics of the cohort and the process and outcomes of the care provided. Data were analysed using descriptive statistics. Regarding effectiveness, the correct care pathway was allocated to 97.5% of women, early access to antenatal care achieved by 95.7% of women, 94.8% of women at one CMU received continuity of carer and 78.6% of those clinically eligible accessed care in labour. 11.9% were appropriately transferred to obstetrician-led care antenatally and 16.9% were transferred in labour. All women received one-to one care in labour and 67.1% of babies born at the CMUs were breastfed at birth. Regarding safety, severe morbidity for women was rare, perineal trauma of 3rd degree tear occurred for 0.3% of women and 1.0% experienced an episiotomy. Severe post partum haemorrhage occurred for 0.3% of women. Babies admitted to the Neonatal unit were discharged within 48 hrs. These findings support the recommendations of professional

Full Text Available Musculoskeletal allografts are now commonly used. To decrease the potential risks of transmission of pathogenic bacteria, fungi, or viruses to the transplant recipients, certain issues regarding the management of patients who receive contaminated allografts need to be addressed. We aimed to clarify the incidence and extent of disease transmission from allografts by analyzing the allografting procedures performed in the bone bank of our hospital over the past 20 years. We retrospectively reviewed the data from our allograft registry center on 3979 allografts that were implanted in 3193 recipients throughout a period of two decades, from July 1991 to June 2011. The source of the allografts, results of all screening tests, dates of harvesting and implantation, and recipients of all allografts were checked. With the help of the Center for Infection Control of our hospital, a strict prospective, hospital-wide, on-site surveillance was conducted, and every patient with healthcare-associated infection was identified. Fisher's exact test was used to compare the infection rate between recipients with sterile allografts and those with contaminated allografts. The overall discard and infection rates were, respectively, 23% and 1.3% in the first decade (1991-2001; and 18.4% and 1.25% in the second decade (2001-2011. The infection rate of contaminated allograft recipients was significantly higher than that of sterile allograft recipients (10% vs. 1.15%, P < 0.01 in the second decade. Both infection and discard rates of our bone bank are comparable with those of international bone banks. Strict allograft processing and adequate prophylactic use of antibiotics are critical to prevent infection and disease transmission in such cases.

Expert guidelines for treatment of cardiac arrest recommend administration of adrenaline (epinephrine) every three to five minutes. However, the effects of different dosing periods of epinephrine remain unclear. We sought to evaluate the association between epinephrine average dosing period and survival to hospital discharge in adults with an in-hospital cardiac arrest (IHCA). We performed a retrospective review of prospectively collected data on 20,909 IHCA events from 505 hospitals participating in the Get With The Guidelines-Resuscitation (GWTG-R) quality improvement registry. Epinephrine average dosing period was defined as the time between the first epinephrine dose and the resuscitation endpoint, divided by the total number of epinephrine doses received subsequent to the first epinephrine dose. Associations with survival to hospital discharge were assessed by using generalized estimating equations to construct multivariable logistic regression models. Compared to a referent epinephrine average dosing period of 4 to <5 min per dose, survival to hospital discharge was significantly higher in patients with the following epinephrine average dosing periods: for 6 to <7 min/dose, adjusted odds ratio [OR], 1.41 (95%CI: 1.12, 1.78); for 7 to <8 min/dose, adjusted OR, 1.30 (95%CI: 1.02, 1.65); for 8 to <9 min/dose, adjusted OR, 1.79 (95%CI: 1.38, 2.32); for 9 to <10 min/dose, adjusted OR, 2.17 (95%CI: 1.62, 2.92). This pattern was consistent for both shockable and non-shockable cardiac arrest rhythms. Less frequent average epinephrine dosing than recommended by consensus guidelines was associated with improved survival of in-hospital cardiac arrest. Copyright © 2013 Elsevier Ireland Ltd.

Full Text Available Background and Aims: The anaesthetic challenge of awake craniotomy is to maintain adequate sedation, analgesia, respiratory and haemodynamic stability in an awake patient who should be able to co-operate during intraoperative neurological assessment. The current literature, sharing the experience on awake craniotomy, in Indian context, is minimal. Hence, we carried out a retrospective study with the aim to review and analyse the anaesthetic management and perioperative complications in patients undergoing awake craniotomy, at our centre. Methods: Medical records of 54 patients who underwent awake craniotomy for intracranial lesions over a period of 10 years were reviewed, retrospectively. Data regarding anaesthetic management, intraoperative complications and post-operative course were recorded. Results: Propofol (81.5% and dexmedetomidine (18.5% were the main agents used for providing conscious sedation to facilitate awake craniotomy. Hypertension (16.7% was the most commonly encountered complication during intraoperative period, followed by seizures (9.3%, desaturation (7.4%, tight brain (7.4%, and shivering (5.6%. The procedure had to be converted to general anaesthesia in one of patients owing to refractory brain bulge. The incidence of respiratory and haemodynamic complications were comparable in the both groups (P > 0.05. There was less incidence of intraoperative seizures in patients who received propofol (P = 0.03. In post-operative period, 20% of patients developed new motor deficit. Mean intensive care unit stay was 2.8 ± 1.9 day (1-14 days and mean hospital stay was 7.0 ± 5.0 day (3-30 days. Conclusions: ′Conscious sedation′ was the technique of choice for awake craniotomy, at our institute. Fentanyl, propofol, and dexmedetomidine were the main agents used for this purpose. Patients receiving propofol had less incidence of intraoperative seizure. Appropriate selection of patients, understanding the procedure of surgery, and

Objective. We compared the treatments of uterine carcinosarcoma at our institution and evaluated their impact on survival. Methods. A retrospective analysis was performed on 60 eligible patients with carcinosarcoma limited to the pelvis. Subjects were divided into four categories: surgery, surgery plus chemotherapy, surgery plus radiation therapy, and a combination of surgery, chemotherapy, and RT. The most commonly used chemotherapy was cisplatin and/or carboplatin and taxol. Radiotherapy included external beam radiation therapy (EBRT) alone or with high dose rate (HDR) brachytherapy or HDR brachytherapy alone. Survival probability data were computed using the Kaplan-Meier method. The differences between groups were compared using the log-rank test. Results. The combination of surgery and radiation therapy with or without chemotherapy is seen to improve overall survival (OS) compared to surgery alone (Ρ =0.044 and Ρ =0.028 resp.). Brachytherapy involving three HDR vaginal cylinder fractions shows an equally effective reduction in local recurrence compared to EBRT. Conclusion. Our study of a relatively large number of carcinosarcoma patients suggests that adjuvant radiation therapy improves OS compared to surgery alone. Brachytherapy with 3 HDR vaginal cylinder fractions is preferred because of its time-saving, better tolerance, low toxicity and equivalent OS, and local control compared to EBRT.

Broncho-vascular fistulas from self-expanding metallic stents: A retrospective case review

Full Text Available To highlight a potentially fatal complication of broncho-vascular fistula arising from the self expanding metallic stent (SEMS placement. We retrospectively analyzed five patients with benign and malignant airway diseases, who developed tracheo/broncho-vascular fistulas following SEMS placement in our tertiary care setting. All patients received either Wallstent or Ultraflex® stent (Boston Scientific, Natick, MA between 1999 and 2007. All patients had received adjunct therapy such as balloon bronchoplasty, laser therapy or electrocautery. Most patients presented with massive hemoptysis. A total of 483 SEMS were placed during this period. SEMS placement can be complicated by Broncho-vascular fistula formation. True incidence and precise time interval between the insertion of stent and onset of this complication is unknown. Additional therapeutic modalities to maintain stent patency may enhance the risk of fistula formation. SEMS should only be used in a select sub-group of patients, after exhaustive evaluation of other treatment options. These cases provide evidence that broncho-vascular fistulas can develop at any time following SEMS placement, suggesting the need for a more cautious approach, especially while using them for a long term management. In benign airway disease, the stent should be removed as soon as healing has taken place.

Retrospective revaluation and its neural circuit in rats.

Contingency learning is essential for establishing predictive or causal judgements. Retrospective revaluation captures essential aspects of the updating of this knowledge, according to new experience. In the present study, retrospective revaluation and its neural substrate was investigated in a rat conditioned magazine approach. One element of a previously food-reinforced Tone-Light compound stimulus was either further reinforced (inflation) or extinguished (extinction). These treatments affected the predictive value of the alternate stimulus (target), but only when the target was a weakly salient stimulus such as a Light, and the inflation/extinction procedure concerned the more salient element, that is the Tone. As the predictive value of the Light was decreased in comparison with a relevant control group, this revaluation was interpreted as backward blocking, and not unovershadowing. This observation challenges retrospective revaluation models focused on acquisition and prediction error detection, and is better accounted for by retrieval-based associative theories such as the comparator model (Miller and Matzel) [5]. Immunohistochemical detection of the Fos protein after the test phase revealed activation of the orbitofrontal and infralimbic cortices as well as nucleus accumbens core and shell, in rats that exhibited retrospective revaluation. Our results suggest that rats integrate successive experiences at the retrieval stage of retrospective revaluation, and that prefronto-accumbal interactions are involved in this function.

A number of long-distance running events are held each year in the United States; the Army Ten Miler (ATM) is one such race held annually in Washington, DC. The purpose of the present study was to retrospectively analyze medical encounters for runners participating in the ATM from 1998 to 2004. Of the estimated 91,750 runners over the 6-year period, 73,100 participants finished the race and were included in the data analysis. Demographic and injury data were collected from medical records of participants who received medical care while participating in the ATM, and injury-related factors were assessed. The most common category of injury was musculoskeletal (44%), followed by medical-related problems (27%) and dermatological injuries (27%). Similar to marathon and ironman races, ATM injury rates correlate with race-day temperature and dew point. Overall, however, the injury rates observed at the ATM were relatively low compared to those reported for longer distance events. Finally, we detail the medical coverage provided at the ATM, as this coverage could be used as a guide for similarly distanced races.

Autonomic dysreflexia is a potentially life-threatening condition which afflicts a significant proportion of individuals with spinal cord injuries (SCI). To date, the safety and efficacy of several commonly used interventions for this condition have not been studied. A retrospective chart review of the safety of a previously implemented nursing driven inpatient autonomic dysreflexia protocol. Seventy-eight male patients with SCI who experienced autonomic dysreflexia while inpatient at our Veterans Affairs SCI unit over a 3-1/2-year period were included. The safety of a nursing driven protocol utilizing conservative measures, nitroglycerin paste, and oral hydralazine was evaluated. Occurrence of adverse events and relative hypotensive events during all episodes treated with the protocol, and efficacy of attaining target blood pressure for all episodes with protocol adherence and for initial episode experienced by each patient. Four hundred forty-five episodes of autonomic dysreflexia were recorded in the study period, with 92% adherence to the protocol. When the protocol was followed, target blood pressure was achieved for 97.6% of all episodes. Twenty-three total adverse events occurred (5.2% of all episodes). All adverse events were due to hypotension and only 0.9% required interventions beyond clinical monitoring. Of each patient's initial autonomic dysreflexia episode, 97.3% resolved using the protocol without need for further escalation of care. This inpatient nursing driven-protocol for treating autonomic dysreflexia utilizing conservative measures, nitroglycerin paste and oral hydralazine achieved target blood pressure with a high success rate and a low incidence of adverse events.

To report the visual outcome and refractive status in first 3 years of age in preterm infants suffered from laser-treated Type 1 retinopathy of prematurity (ROP): a 6-year review in Hong Kong DESIGN: Retrospective case series METHODOLOGY: Clinical records of all infants suffered from Type 1 ROP who had undergone laser therapy between 2007 and 2012 were retrospectively reviewed. Basic demographic data, serial changes of refractive error, visual acuity, severity of ROP and laser were analyzed. Correlation with myopia and astigmatism progression, body weight, height, growth and gestational age were also analyzed. Among 494 babies screened, 14 Chinese babies (26 eyes) recruited with 1:1 male-to-female ratio in this study. All eyes showed gradual progression of myopia in first 3 years of age but no significant change of astigmatism. Further correlation analysis showed no correlation with laser energy consumed, birth weight (p = 0.14), head circumference growth (p = 0.57) and body weight growth (p = 0.71). However, severity of myopia was related to the post-conceptual age when receiving laser therapy (p < 0.005), gestation age (p = 0.02) and possibly body height growth with age (p = 0.05). Myopia in early life is one of the most common ocular sequelae in Type 1 ROP survivors. Early detection of refractive error is important for prompt correction and visual rehabilitation to prevent amblyopia.

Medical leave granted to psychiatric inpatients--a one-year retrospective review.

Of the 676 patients warded in 1998 at the National University Hospital (NUH) Department of Psychological Medicine, over a third (n = 268) required certification of absence from work. Duration of inpatient stay and immediate post-discharge medical leave were examined for this group. These durations were correlated against the patients' diagnoses and their demographic variables. The mental health morbidity of teachers was specifically studied. In this retrospective study, we used medical certificate counterfoils to determine the lengths of admission and post-discharge medical leave duration. ANOVA and Kruskal-Wallis tests of the SPSS computer package were used for statistical analysis. The sex and marital status of these patients did not affect either duration significantly. However, those 45 years and older were granted longer outpatient medical leave. Patients diagnosed with mood and psychotic disorders required longer inpatient stay and were granted longer outpatient medical leave, as compared with other diagnostic groups. It was found that the teachers admitted were largely 45 years and older, had a diagnosis of depression and required extended periods of outpatient medical leave compared to other occupational groups. The mean number of days of inpatient stay and outpatient medical leave may serve as a helpful guideline of current practice. As introduced in this paper, the use of medical certificate counterfoils is a simple yet effective way of measuring days off-work. With the inclusion of those psychiatric patients not working and the medical leave granted long after discharge, calculations of the economic costs of specific mental disorders to Singapore can then be attempted.

Erythropoiesis stimulating agents [erythropoietin (EPO)] have been recommended to treat anaemic patients who cannot receive or refuse blood tranfusion ('untransfusable' patients). The objective of the study was to quantify the association of EPO use with haemoglobin (Hgb) recovery in anaemic untransfusable hospitalised patients. EPO treated anaemic untransfusable patients were identified through the combination of a retrospective case review and a systematic review of the medical literature. Literature reports of untransfusable patients not treated with any EPO were used as a comparator group. Hgb concentrations before and following EPO use were abstracted and used to determine the rate of Hgb recovery for each case. Multilevel mixed effects modelling was used to determine the association of Hgb recovery with EPO use. A total of 76 EPO treated cases (19 cases from the retrospective hospital case review and 57 from the literature), and 33 non-EPO treated comparator patients from the literature were included in the study. Hgb increased similarly over time in all groups at an overall mean standard error (SE) rate of 0·13 (0·01) g dL(-1)  day(-1) . The Hgb recovery rate was higher in patients with lower baseline Hgb, regardless of EPO use. No association was found between the rate of Hgb recovery and EPO use, dose or therapy duration. In anaemic, 'untransfusable' hospitalised patients, EPO use was not associated with increased Hgb recovery at anytime within 28 days. © 2014 The Authors.

Background: Little is known regarding image quality and the required radiation dose for step-and-shoot and retrospective coronary computed tomography angiography (CCTA) with tube current modulation (TCM) in 128-slice multidetector CT (MDCT) coronary angiography. Purpose: To compare image quality and radiation dose in patients who underwent 128-slice MDCT by the step-and- shoot method with those in patients who underwent 128-slice MDCT with retrospective CCTA with TCM. Material and Methods: CCTA obtained with 128-slice MDCT was retrospectively evaluated in 160 patients. Two independent reviewers separately scored the subjective image quality of the coronary artery segments (1, excellent; 4, poor) for step-and-shoot (68, mean heart rate [HR]: 59.3±6.8) and retrospective CCTA with TCM (77, mean HR: 59.1±9.8). Interobserver variability was calculated. Effective radiation doses of both scan techniques were calculated with dose-length product. Results: There was good agreement for quality scores of coronary artery segment images between the independent reviewers (k=0.72). The number of coronary artery segments that could not be evaluated was 2.85% (27 of 947) in the step-and-shoot and 1.87% (20 of 1071) in retrospective CCTA with TCM. Image quality scores were not significantly different (P>.05). Mean patient radiation dose was 63% lower for step-and-shoot (1.94±0.70 mSv) than for retrospective CCTA with TCM (4.51±1.18 mSv) (P<0.0001). For patients who underwent step-and-shoot or retrospective CCTA with TCM, an average HR of 63.5 beats per minute was identified as the threshold for the prediction of non-diagnostic image quality for both protocols. There were no significant differences in the image quality of both methods between obese (body mass index [BMI≥25) and non-obese patients (BMI<25), but radiation doses were higher in the obesity group than in the non-obesity group for both methods. Conclusion: Both step-and-shoot and retrospective CCTA with TCM using 128

Air ambulance transport for injured patients is vitally important given increasing patient volumes, the limited number of trauma centres and inadequate subspecialty coverage in nontrauma hospitals. Air ambulance services have been shown to improve patient outcomes compared with ground transport in select circumstances. Our primary goal was to compare injuries, interventions and outcomes in patients transported by helicopter versus nonhelicopter transport. We performed a retrospective 10-year review of 14 440 patients transported to an urban Level 1 trauma centre by helicopter or by other means. We compared injury severity, interventions and mortality between the groups. Patients transported by helicopter had higher median injury severity scores (ISS), regardless of penetrating or blunt injury, and were more likely to have Glasgow Coma Scale scores less than 8, require airway control, receive blood transfusions and require admission to the intensive care unit or operating room than patients transported by other means. Helicopter transport was associated with reduced overall mortality (odds ratio 0.41, 95% confidence interval 0.33-0.39). Patients transported by other methods were more likely to die in the emergency department. The mean ISS, regardless of transport method, rose from 12.3 to 15.1 (p = 0.011) during our study period. Patients transported by helicopter to an urban trauma centre were more severely injured, required more interventions and had improved survival than those arriving by other means of transport.

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

Diabetes self-management education (DSME) and medical nutrition therapy (MNT) improve patient outcomes; poor reimbursement limits access to care. Our aim was to develop methodology for tracking patient outcomes subsequent to registered dietitian nutritionist interventions, document outcomes for patients with type 2 diabetes attending an American Diabetes Association-recognized program, and obtain outcome data to support reimbursement and public policy initiatives to improve patient access to DSME and MNT. Retrospective chart review. A random sample of 100 charts was chosen from the electronic medical records of patients with type 2 diabetes completing DSME and individualized MNT, June 2013 to 2014. Data were extracted on body mass index (calculated as kg/m 2 ), weight, hemoglobin A1c, blood glucose, and lipids. Mixed-model analysis of variance was used to determine differences between means for continuous variables; McNemar's tests and γ-statistic trend analysis were used to assess frequency of patients reaching glycemic targets. Significant weight loss was observed from baseline (94.3±21.1 kg) to end of program (91.7±21.2 kg [-1.6±3.9 kg]; P0.05). Significant hemoglobin A1c reduction was observed from baseline (8.74%±2.30%) to end of program (6.82%±1.37% [-1.92%±2.25%]; Phemoglobin A1c targets (≤7.0%) vs 27% at baseline (P=0.008). When stratified by diet alone and diet plus drug therapy, patients exhibited a 1.08%±1.20% (Phemoglobin A1c, respectively. Triglycerides decreased from baseline 181.6±75.5 mg/dL (2.0±0.9 mmol/L) to 115.8±48.1 mg/dL (1.3±0.5mmol/L) (P=0.023). High-density lipoprotein increased from 41.4±12.4 mg/dL (1.1±0.3 mmol/L) to 47.3±12.4 mg/dL (1.2±0.3 mmol/L) (P=0.007). Retrospective chart review provides an operational model for abstracting existing patient outcome data subsequent to registered dietitian nutritionist interventions.

Purpose To assess the incidence of costal cartilage (CC) fractures in whole-body computed tomographic (CT) examinations for blunt trauma and to evaluate distribution of CC fractures, concomitant injuries, mechanism of injury, accuracy of reporting, and the effect on 30-day mortality. Materials and Methods Institutional review board approval was obtained for this retrospective study. All whole-body CT examinations for blunt trauma over 36 months were reviewed retrospectively and chest trauma CT studies were evaluated by a second reader. Of 1461 patients who underwent a whole-body CT examination, 39% (574 of 1461) had signs of thoracic injuries (men, 74.0% [425 of 574]; mean age, 46.6 years; women, 26.0% [149 of 574]; mean age, 48.9 years). χ 2 and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Interobserver agreement was calculated by using Cohen kappa values. Results A total of 114 patients (men, 86.8% [99 of 114]; mean age, 48.6 years; women, 13.2% [15 of 114]; mean age, 45.1 years) had 221 CC fractures. The incidence was 7.8% (114 of 1461) in all whole-body CT examinations and 19.9% (114 of 574) in patients with thoracic trauma. Cartilage of rib 7 (21.3%, 47 of 221) was most commonly injured. Bilateral multiple consecutive rib fractures occurred in 36% (41 of 114) versus 14% (64 of 460) in other patients with chest trauma (OR, 3.48; 95% CI: 2.18, 5.53; P chest trauma with CC fractures (13%, 15 of 114) versus patients with chest trauma without CC fractures (4%, 18 of 460) (OR, 3.72; 95% CI: 1.81, 7.64; P = .0001), as well as aortic injuries (n = 4 vs n = 0; P = .0015; OR, unavailable). Kappa value for interobserver agreement in detecting CC fractures was 0.65 (substantial agreement). CC fractures were documented in 39.5% (45 of 114) of primary reports. The 30-day mortality of patients with CC fractures was 7.02% (eight of 114) versus 4.78% (22 of 460) of other patients with chest trauma (OR, 1.50; 95% CI: 0.65, 3.47; P = .3371). Conclusion

Refeeding syndrome describes a pattern of electrolyte disturbances occurring after the reintroduction of nutrition to the malnourished patient; it is often associated with delirium. The authors investigated whether hospitalized elderly patients who develop delirium are more likely to have laboratory findings consistent with refeeding syndrome. The authors conducted a retrospective chart review of 100 patients over age 60. Charts were examined for indications of delirium and refeeding syndrome. Significantly lower serum levels of magnesium and phosphate were found in patients with delirium. Delirium was not associated with any significant difference in levels of potassium. This study supports an association between delirium in elderly patients and electrolyte changes consistent with those seen in refeeding syndrome.

To explore the utility of endoscopic ultrasound (EUS) in the evaluation of chronic upper abdominal pain (UAP) of undetermined etiology. Chronic UAP is a common problem with a challenging diagnosis and management. The role of EUS in the diagnosis of UAP may minimize additional testing; however, few studies describe the percentage of new diagnoses yielded in these patients. We conducted a retrospective analysis by reviewing electronic medical records at Scott and White Memorial Hospital, Texas A&M Health Sciences Center for patients with abdominal pain for ≥ 12 months not explained by previous workup referred for EUS for chronic UAP from January 1, 1998 through October 1, 2007. Patients with previous EUS in past 12 months were excluded from the study. Patient demographic data and imaging performed 6 months before and 24 months after EUS were reviewed and results documented. EUS was successful at diagnosing a new clinical etiology of chronic UAP in 33 patients (8.89%) with previous workup that was unrevealing for a definitive diagnosis. The most frequent diagnoses included pancreaticobiliary tree abnormalities, chronic pancreatitis, and fatty liver disease. Our results support the fact that the majority of patients UAP with prior imaging will have no identifiable organic etiology found on EUS to explain their pain; however, we suggest that EUS be considered in patients with suspected pancreatic or biliary pathology.

We reviewed 42 cases of deep neck abscess drained surgically or treated conservatively between February 2001 and August 2008, based on age, gender, primary focus, main symptom, abscess location, systemic disease, pathogenic bacteria, hospital treatment, hospitalization length, complications and long-term hospitalization. Of the 42, 26 were men and 16 women aged 14 to 80 (central age: 54.5 years). Abscess was caused most by tonsil inflammation (38.1%). Main symptom were sore throat (54.8%) and neck swelling (35.7%). Abscesses were found in the supra- and infrahyoid region in 30 cases and extended to the mediastinum in 2. Of the 42, 14 (33.3%) had hypertension and 11 (26.2%) diabetes mellitus (DM). Inflammation was due to aerobic bacteria (mainly Streptococcus milleri) in 23 cases (54.8%) and to anaerobic bacteria (mainly Peptostreptococcus) in 11 cases (26.2%). Flexible fiberscopic examination was important in evaluating pharyngeal and laryngeal mucosal disorders and enhanced computed tomography was useful in both diagnosis and postoperative observation. Of the 42, 38 required surgical drainage and 4 were cured using needle aspiration and antibiotics. Of the 38 undergoing surgery-tracheostomy was required in 22. Hospitalization for those with tracheostomy and DM was longer than in those without these factors. Complications included 2 cases each of, mediastinal abscess, sepsis, disseminated intravascular coagulation (DIC), acute renal failure, severe pneumonia, upper digestive tract bleeding and swallowing disorder. Early surgical drainage and intravenous antibiotic administration are thus essential for treating deep neck abscesses. (author)

Few clinical studies have assessed the efficacy and safety of oxcarbazepine (OXC) oral suspension in Asian pediatric patients and particularly in infants. The aim of this study was to investigate and compare the efficacy, tolerability, and side effects of OXC oral suspension in Taiwanese infants and children with various types of epilepsy. A retrospective review of the efficacy, tolerability, and side effects of OXC oral suspension in a tertiary medical center in Taiwan was conducted and included children (1-9 years old) and infants (effects (30 vs. 21 %, p = 0.525) after OXC oral suspension treatment. The efficacy was significantly correlated with the epilepsy subtype (p effective and well tolerated in both infants and children with partial epilepsy in Taiwan. Treatment efficacy was related to epilepsy subtype and number of combined AEDs before OXC treatment. Monotherapy had an excellent therapeutic response in partial epilepsy but not in multifocal epilepsy.

Celalettin Sever

2011-09-01

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.

While it is known that diesel fuel combustion engines produce much lower concentrations of carbon monoxide (CO) than gasoline engines, these emissions could certainly generate lethal ambient concentrations given a sufficient amount of time in an enclosed space and under suitable environmental conditions. The authors report a case of CO poisoning which was initially referred for autopsy as a presumed natural death of a truck driver found in the secure cab of a running diesel tractor trailer truck. Completion of the preliminary investigation ascribed death to complications of ischemic heart disease (IHD), pending toxicological analysis that included quantification of CO. When the toxicology results showed lethal blood COHbg, the cause of death was re-certified as CO intoxication secondary to inhalation of (diesel) vehicular exhaust fumes. Because of the unique source of fatal CO intoxication in this case, the contributory IHD and the possible contaminants in the putrefied blood, a 10-year retrospective review was conducted on all nonfire related CO deaths autopsied (n = 94) at the Office of the Chief Medical Examiner in Louisville, KY from 1994 to 2003. For validation of the COHbg detection method used by the Kentucky Office of Forensic Toxicology (KYOFT), blood samples from these cases along with controls were submitted to three laboratories using various analytical methods yielding no statistically significant differences. Lastly, an extensive literature review produced no scientifically reported cases of fatal CO poisoning attributed to diesel fuel exhaust.

To evaluate the rate of short-term complications associated with microwave ablation of lung tumors located near the heart. This HIPAA-compliant study was performed with a waiver for informed consent. Patients who underwent microwave ablation of lung tumors located 10 mm or less from the heart were identified by retrospective chart review. Both primary and metastatic tumors were included. Only tumors directly adjacent to one of the four cardiac chambers were included. All patients were treated in a single session using CT guidance with continuous electrocardiographic monitoring. Rates of new-onset arrhythmia and myocardial infarction (MI) within 90 days of the procedure were quantified, and evidence of cardiac or pericardiac injury was assessed for using post-ablation contrast-enhanced chest CT, electrocardiography (EKG), and-when available-echocardiography. Complications were graded using the Common Terminology Criteria for Adverse Events (CTCAE) system. Ten patients (four males, six females; mean age 73.1 ± 9.5 years) met all inclusion criteria. Mean tumor distance from the heart was 3 mm (range, 0-6 mm). New-onset arrhythmia was not observed during or following any of the microwave ablation treatments, and there were no documented 90-day MI events. CTCAE Grade 1 complications were observed by CT in eight patients, most commonly mild focal pericardial thickening. EKG and echocardiography were normal in all patients. No major complications (CTCAE Grade 3 or greater) were observed. Microwave ablation of lung tumors located 10 mm or less from the heart appears to have low associated short-term morbidity and may be appropriate in selected patients.

External inspections are widely used in health care as a means of improving the quality of care. However, the way external inspections affect the involved organization is poorly understood. A better understanding of these processes is important to improve our understanding of the varying effects of external inspections in different organizations. In turn, this can contribute to the development of more effective ways of conducting inspections. The way the inspecting organization states their grounds for noncompliant behavior and subsequently follows up to enforce the necessary changes can have implications for the inspected organization's change process. We explore how inspecting organizations express and state their grounds for noncompliant behavior and how they follow up to enforce improvements. We conducted a retrospective review, in which we performed a content analysis of the documents from 36 external inspections in Norway. Our analysis was guided by Donabedian's structure, process, and outcome model. Deficiencies in the management system in combination with clinical work processes was considered as nonconformity by the inspecting organizations. Two characteristic patterns were identified in the way observations led to a statement of nonconformity: one in which it was clearly demonstrated how deficiencies in the management system could affect clinical processes, and one in which this connection was not demonstrated. Two characteristic patterns were also identified in the way the inspecting organization followed up and finalized their inspection: one in which the inspection was finalized solely based on the documented changes in structural deficiencies addressed in the nonconformity statement, and one based on the documented changes in structural and process deficiencies addressed in the nonconformity statement. External inspections are performed to improve the quality of care. To accomplish this aim, we suggest that nonconformities should be grounded by

Full Text Available Safe anaesthesia is a crucial component of safe surgical care, yet anaesthetic complications are common in resource-limited settings. We describe differences in anaesthetic needs for Mandibulectomy vs. Maxillectomy in three sub-Saharan African countries.Retrospective review of patients undergoing minor Mandibulectomy, major Mandibulectomy, or Maxillectomy in Togo, Guinea and Republic of the Congo. Surgeries were performed on the Africa Mercy, an international non-governmental hospital ship. Primary outcomes were need for advanced airway management and intra-operative blood loss. Secondary outcomes were time under general anaesthesia and hospital length of stay. Multivariate regression determined the association between operation type and each outcome measure.105 patients were included (25 minor Mandibulectomy, 58 major Mandibulectomy, 22 Maxillectomy procedures. In-hospital mortality was 0%. 44/105 (41.9% required an advanced airway management technique to achieve intubation, although in all cases this was anticipated prior to the procedure; no differences were noted between surgical procedure (p = 0.72. Operative procedure was a significant risk factor for intra-operative blood loss. Patients undergoing Maxillectomy lost on average 851.5 (413.3, 1289.8, p = 0.0003 mL more blood than patients undergoing minor Mandibulectomy, and 507.3 (150.3, 864.3, p = 0.007 mL more blood than patients undergoing major Mandibulectomy. Patients undergoing Maxillectomy had a significantly higher time under general anaesthesia than those undergoing minor Mandibulectomy. There was no significant difference in hospital length of stay between operation type.Anaesthetic considerations for minor Mandibulectomy, major Mandibulectomy, and Maxillectomy differ with respect to intra-operative blood loss and time under general anaesthesia, but not need for advanced airway management or length of stay. Although advanced airway management was required in 41.9% of patients

To examine the development and implementation of a novel income security intervention in primary care. A retrospective, descriptive chart review of all patients referred to the Income Security Heath Promotion service during the first year of the service (December 2013-December 2014). A multisite interdisciplinary primary care organisation in inner city Toronto, Canada, serving over 40 000 patients. The study population included 181 patients (53% female, mean age 48 years) who were referred to the Income Security Health Promotion service and engaged in care. The Income Security Health Promotion service consists of a trained health promoter who provides a mixture of expert advice and case management to patients to improve income security. An advisory group, made up of physicians, social workers, a community engagement specialist and a clinical manager, supports the service. Sociodemographic information, health status, referral information and encounter details were collected from patient charts. Encounters focused on helping patients with increasing their income (77.4%), reducing their expenses (58.6%) and improving their financial literacy (26.5%). The health promoter provided an array of services to patients, including assistance with taxes, connecting to community services, budgeting and accessing free services. The service could be improved with more specific goal setting, better links to other members of the healthcare team and implementing routine follow-up with each patient after discharge. Income Security Health Promotion is a novel service within primary care to assist vulnerable patients with a key social determinant of health. This study is a preliminary look at understanding the functioning of the service. Future research will examine the impact of the Income Security Health Promotion service on income security, financial literacy, engagement with health services and health outcomes. © Article author(s) (or their employer(s) unless otherwise stated in

2017-03-01

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.

Isolated premature menarche is isolated or recurrent vaginal bleeding in a female in the absence of appropriate secondary sexual characters. Retrospective chart review of patients with premature menarche, followed by a telephone questionnaire. Charts of patients evaluated in the Pediatric Endocrine Clinic for premature vaginal bleeding from 1982-2013 were reviewed. Of 21 patients identified, 17 could be contacted. Five newly diagnosed patients were recruited during the course of the study. The median age at initial presentation was 7 years. Most patients presented with Tanner I sexual development. Some had more advanced breast staging, which regressed later. All had prepubertal baseline and stimulated gonadotropins. Most of the patients reported a single or few episodes of menses. Two reported continuation of irregular bleeding into adulthood. All reported an adult height within the midparental target height. Premature menarche in the absence of other appropriate secondary sexual characteristics is a benign entity. Most patients have a few isolated episodes of menses that stop spontaneously; some may continue to have periods into adulthood. Unlike true puberty, these patients do not demonstrate advanced skeletal maturation, and the adult height is normal. Fertility appears to be normal. © 2015 S. Karger AG, Basel.

This article provides a selective review of time perception research, mainly focusing on the authors' research. Aspects of psychological time include simultaneity, successiveness, temporal order, and duration judgments. In contrast to findings at interstimulus intervals or durations less than 3.0-5.0 s, there is little evidence for an "across-senses" effect of perceptual modality (visual vs. auditory) at longer intervals or durations. In addition, the flow of time (events) is a pervasive perceptual illusion, and we review evidence on that. Some temporal information is encoded All rights reserved. relatively automatically into memory: People can judge time-related attributes such as recency, frequency, temporal order, and duration of events. Duration judgments in prospective and retrospective paradigms reveal differences between them, as well as variables that moderate the processes involved. An attentional-gate model is needed to account for prospective judgments, and a contextual-change model is needed to account for retrospective judgments. Copyright © 2013 Elsevier B.V.

2017-01-01

To describe the use of prehospital ultrasonography (PHUS) to support interventions, when used by physician and non-physician air medical crew (AMC), in a Canadian helicopter emergency medical service (HEMS). A retrospective review was conducted of consecutive patients who underwent ultrasound examination during HEMS care from January 1, 2009 through March 10, 2014. An a priori created data form was used to record patient demographics, type of ultrasound scan performed, ultrasound findings, location of scan, type of interventions supported by PHUS, factors that affected PHUS completion, and quality indicator(s). Data analysis was performed through descriptive statistics, Student's t-test for continuous variables, Z-test for proportions, and Mann-Whitney U Test for nonparametric data. Outcomes included interventions supported by PHUS, factors associated with incomplete scans, and quality indicators associated with PHUS use. Differences between physician and AMC groups were also assessed. PHUS was used in 455 missions, 318 by AMC and 137 by physicians. In combined trauma and medical patients, in the AMC group interventions were supported by PHUS in 26% of cases (95% CI 18-34). For transport physicians the percentage support was found to be significantly greater at 45% of cases (95% CI 34-56) p = reasons included patient obesity, lack of time, patient access, and clinical reasons. Quality indicators associated with PHUS were rarely identified. The use of PHUS by both physicians and non-physicians was found to support interventions in select trauma and medical patients.

Obesity impacts the physical and psychological health of children and adolescents, and is a risk factor for development of episodic and chronic illness. Rural Mexican-American adolescents are at risk for obesity and associated chronic illnesses.The study used a retrospective chart review of data collected routinely in a rural health clinic setting from 1 January 2005 to 31 December 2010 to assess incidence of overweight/obesity status and episodic or chronic illness among Mexican-American adolescents aged 12-18 years. Analyses included body mass index, age, gender, and episodic or chronic illness diagnoses. Two hundred twelve charts were audited; women (n = 114, 53.8%), men (n = 98 46.2%); normal (n = 105, 49.5%), overweight/obese (n = 107, 50.5%). There were more female normal (n = 61, 53.5%) vs. overweight/obese (n = 53, 46.5%). More male overweight/obese (n = 54, 55.1%) than normal weight (n = 44, 44.9%). Age at first documented overweight/obesity status occurred in early adolescence (median = 13 years, mode = 12 years). Chronic illness incidence was higher among men than women, and overweight/obese vs. normal weight adolescents and in sub-categorizations by weight and specific illness. Incidence of episodic illness was higher among women than men, with variation by weight and specific illness. Disproportionately high incidence of episodic or chronic illness and overweight/obesity identified among rural Mexican-American adolescents compels intervention modification to improve effectiveness. © 2014 Wiley Publishing Asia Pty Ltd.

No data exists that directly compares hemoglobin and hematocrit levels between cancer patients with and without occurrence of thrombosis during treatment with erythropoiesis stimulating agents (ESAs). To determine the association of hemoglobin and hematocrit levels with the occurrence of thrombosis in cancer patients treated with ESAs. A retrospective case-control study approved by the Institutional Review Board was conducted on cancer patients billed for epoetin or darbepoetin between 1 July 2002 and 30 June 2007. Cases were defined as patients billed for thrombosis while controls were defined as patients not billed for thrombosis. Sixteen patients had an occurrence of thrombosis (cases) and were matched to 16 patients that did not have an occurrence of thrombosis (controls) based on age, sex, and cancer type. The mean peak hemoglobin levels for cases and controls were 12.6 +/- 1.2 g/dL versus 12.6 +/- 1.4 g/dL (p = 0.9). The mean peak hematocrit levels for cases and controls were 37.3 +/- 3.8% versus 37.9 +/- 4.3% (p = 0.8). For the 16/586 (2.7%) patients with thrombosis, the mean hemoglobin and hematocrit at time of thrombosis were 9.6 +/- 1.0 g/dL and 28.9 +/- 3.1%. A significant identifiable risk factor for thrombosis between the cases and controls was history of thrombosis 31.3% versus 0% (p = 0.04). There was no statistical difference in peak hemoglobin and hematocrit levels between patients with thrombosis and those without thrombosis. Further study is warranted to determine if these levels are true risk factors for thrombosis.

Pigeons discriminated between two pairs of durations: a short set (2.5 and 5 sec) and a long set (5 and 10 sec). The pairs were intermixed within sessions and identified by the colors on the signal and choice keys. Once the task was learned, the pigeons experienced the following three conditions seriatim: (1) The signal key was made ambiguous about the test change, but the choice keys were informative (retrospective); (2) the signal key identified the test range, but the choice keys did not (prospective); (3) probe trials were introduced in which the color of the center key signaled one test range, but the color of the choice keys signaled the other test range (inconsistent). Accuracy of choice decreased in the retrospective condition and, returned to baseline levels, was higher under the prospective condition than under the retrospective condition. In a final condition, referred to as conflict trials, the center-key color signified one test range and the choice-key colors the other range. The results from these conflict-inconsistent tests indicate that choice behavior was largely controlled by the signal-key color and not by the choice-key color. We relate these findings to different approaches to timing in animals.

Ultimately, these datas have been compared with those in the reputable books and new medical papers; And the results are present at the end of the discussion. Undoubtedly, this study is not free of the limitations of retrospective studies. Our patients-contrary to the textbooks are predominantly males; And also their most common chief complaints are neurological manifestations, and headache (82% is the most common one. There is only a little difference in the prevalence of some of the endocrinologic and ophthalmic manifestations between our datas and what in the texts, while, in some others, we can see a great diversity between the 2. For instance, decreased libido in men and amenorrhea in women, among our patients are prominently less than what we study in the books; And blood pressure disturbances, sensory and motor symptoms and urinary incontinence have not been seen in our patients. In most cases, CT scan leads to diagnosis and its diagnostic accuracy in 2 times higher than that of the simple radiography and it can show the sella enlargement obviously. In a majority of cases (More than 95%, excision a part of the tumor (From just limited to the biopsy area to 90% of tumor mass was the only therapeutic measure. In only a few patients, tumor excision was followed by radiotherapy, that showed the better results. The most common delayed complication was the recurrence of the disease.

The aim was to describe the strengths and weaknesses, from team member perspectives, of working with the Global Trigger Tool (GTT) method of retrospective record review to identify adverse events causing patient harm. A qualitative, descriptive approach with focus group interviews using content analysis. 5 Swedish hospitals in 2011. 5 GTT teams, with 5 physicians and 11 registered nurses. 5 focus group interviews were carried out with the five teams. Interviews were taped and transcribed verbatim. 8 categories emerged relating to the strengths and weaknesses of the GTT method. The categories found were: Usefulness of the GTT, Application of the GTT, Triggers, Preventability of harm, Team composition, Team tasks, Team members' knowledge development and Documentation. Gradually, changes in the methodology were made by the teams, for example, the teams reported how the registered nurses divided up the charts into two sets, each being read respectively. The teams described the method as important and well functioning. Not only the most important, but also the most difficult, was the task of bringing the results back to the clinic. The teams found it easier to discuss findings at their own clinics. The GTT method functions well for identifying adverse events and is strengthened by its adaptability to different specialties. However, small, gradual methodological changes together with continuingly developed expertise and adaption to looking at harm from a patient's perspective may contribute to large differences in assessment over time.

Objective: To compare image quality, diagnostic accuracy and radiation dose of prospective and retrospective electrocardiogram (ECG) gated dual source computed tomography (DSCT) for the evaluation of the coronary stent, using conventional coronary angiography (CA) as a standard reference. Design, setting and patients: Sixty patients (heart rates {<=}70 bpm) with previous stent implantation who were scheduled for CA were divided in two groups, receiving either prospective or retrospective ECG gated DSCT separately. Two reviewers scored coronary stent image quality and evaluated stent lumen. Results: There was no significant difference in image quality between the two groups. In the prospective group, there were 86.4% (51/59) stents with interpretable images, in the retrospective group, there were 87.5% (49/56) stents with interpretable images. Image quality was not influenced by age, body mass index or heart rate in either group, but heart rate variability had a weak impact on the image quality of the prospective group. Image noise was higher in the prospective group, but this difference reached statistical significance only by using a smooth kernel reconstruction. Per-stent based sensitivity, specificity, and positive and negative predictive value were 100%, 84.1%, 68.2%, and 100%, respectively, in the prospective CT angiography group and 94.4%, 86.8%, 77.3%, and 97.1%, respectively, in the retrospective CT angiography group. There was a significant difference in the effective radiation dose between the two groups, mean effective dose in the prospective and retrospective group was 2.2 {+-} 0.5 mSv (1.5-3.2 mSv) and 14.6 {+-} 3.3 mSv (10.0-20.4 mSv) (p < .001) respectively. Conclusions: Compared with retrospective CT angiography, prospective CT angiography has a similar performance in assessing coronary stent patency, but a lower effective dose in selected patients with regular heart rates {<=}70 bpm.

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.

Drago, Carl

2016-08-01

The purpose of this report was to retrospectively evaluate implant and immediate full-arch prosthesis survival rates over a 24-month period; patients were consecutively treated with immediate occlusal loading. Dental arch, gender, and implant orientation (vertical vs. tilted) were also noted. All Brånemark System implants (Nobel Active) and interim, all-acrylic resin prostheses placed in patients following an All-on-Four™ protocol, in a single private practice were assessed by retrospective patient chart review. The amount of space provided surgically for implant restorative components and prostheses was determined from measurements of the vertical heights of the interim prostheses in the right/left anterior and posterior segments. These measurements were made in the laboratory. Interim prosthetic repairs (type, frequency, length of time from insertion) were analyzed by type, arch, gender, and implant orientation. Implant survival and insertion torque values were also measured. Inclusion criteria consisted of all Brånemark System implants placed with the All-on-Four protocol from September 1, 2011, until August 31, 2013. Specific dietary instructions were given for the first 7 days immediately postoperatively and for the weeks prior to insertion of the definitive prostheses. One hundred twenty-nine patients, comprising 191 arches (766 implants) from September 1, 2011, until August 31, 2013, were included in the study. One patient experienced implant failure yielding an overall implant survival rate (SR) of 99.5% (762 of 766). Four hundred twenty-six of 430 maxillary implants and 336 of 336 mandibular implants survived for SRs of 99.1% and 100%, respectively. Regarding implant orientation, 415 of 417 tilted implants (SR 99.5%) and 343 of 345 (CSR 95.6%) vertical implants were noted to be clinically stable. Interim, all-acrylic resin prostheses were in place for a mean of 199.2 days; mandibular prostheses were in place for an average of 195.4 days; maxillary

The circumferential resection margin (CRM) is a key prognostic factor after rectal cancer resection. We sought to identify factors associated with CRM involvement (CRM+). A retrospective review was performed of the National Cancer Database, 2004-2011. Patients with rectal cancer who underwent radical resection and had a recorded CRM were included. Multivariable analysis of the association between clinicopathologic characteristics and CRM was performed. Tumor CRM+. Of 23,464 eligible patients, 13.3% were CRM+. Factors associated with CRM+ were diagnosis later in the study period, lack of insurance, advanced stage, higher grade, undergoing APR, and receiving radiation. Nearly half of CRM+ patients did not receive neoadjuvant therapy. CRM+ patients who did not receive neoadjuvant therapy were more likely to be female, older, with more comorbidities, smaller tumors, earlier clinical stage, advanced pathologic stage, and CEA-negative disease compared to those who received it. Factors associated with CRM+ include features of advanced disease, undergoing APR, and lack of health insurance. Half of CRM+ patients did not receive neoadjuvant treatment. These represent cases where CRM status may be modifiable with appropriate pre-operative selection and multidisciplinary management. Copyright © 2016 IJS Publishing Group Limited.

Retrospective Revaluation: The Phenomenon and Its Theoretical Implications

Science.gov (United States)

Miller, Ralph R.; Witnauer, James E.

2015-01-01

Retrospective revaluation refers to an increase (or decrease) in responding to conditioned stimulus (CS X) as a result of decreasing (or increasing) the associative strength of another CS (A) with respect to the unconditioned stimulus (i.e., A-US) that was previously trained in compound with the target CS (e.g., AX−US or just AX). We discuss the conditions under which retrospective revaluation phenomena are most apt to be observed and their implications for various models of learning that are able to account for retrospective revaluation (e.g., Dickinson and Burke, 1996; Miller and Matzel, 1988; Van Hamme and Wasserman, 1994). Although retroactive revaluation is relatively parameter specific, it is seen to be a reliable phenomenon observed across many tasks and species. As it is not anticipated by many conventional models of learning (e.g., Rescorla and Wagner, 1972), it serves as a critical benchmark for evaluating traditional and newer models. PMID:26342855

Patients suffering from major depressive disorder are more likely to suffer from alcohol use disorder. The data is inconclusive for the effectiveness of antidepressant treatment of patients suffering from both illnesses in regards to improving sobriety and reducing alcohol-related healthcare expenses such as hospitalizations. The objective of this study is to determine if a new prescription of an antidepressant upon inpatient discharge is associated with a reduction in the number of future acute alcohol-related hospital readmissions to the same institution in patients suffering from major depressive disorder and alcohol-use disorder. A retrospective, medical record review study was conducted at a publicly-supported hospital in Sylmar, CA. A query was performed for adult patients admitted between 1/1/2005-12/31/2013 who had ICD-9 codes for both alcohol-use disorder and depression. Index admission was the first hospitalization in which the patient was currently consuming alcohol and had depression as identified by physician documentation as a problem. Acute alcohol-related admissions were those for alcohol intoxication or withdrawal (indicating current alcohol use). Patients were excluded if they were receiving an antidepressant on index admission, depressive disorder with a prescription for an antidepressant is not associated with a reduction in future readmissions, nor significantly increase the number of days to readmission. The study does not support the concept of antidepressants in reducing acute alcohol-related readmissions.

Identification of risk factors predicting the development of death rattle. Respiratory tract secretions, often called death rattle, are among the most common symptoms in dying patients around the world. It is unknown whether death rattle causes distress in patients, but it has been globally reported that distress levels can be high in family members. Although there is a poor evidence base, treatment with antimuscarinic medication is standard practice worldwide and prompt intervention is recognised as crucial for effectiveness. The identification of risk factors for the development of death rattle would allow for targeted interventions. A case ̶ control study was designed to retrospectively review two hundred consecutive medical records of mainly cancer patients who died in a hospice inpatient setting between 2009 - 2011. Fifteen potential risk factors including the original factors weight, smoking, final opioid dose and final Midazolam dose were investigated. Binary logistic regression to identify risk factors for death rattle development. Univariate analysis showed death rattle was significantly associated with final Midazolam doses and final opioid doses, length of dying phase and anticholinergic drug load in the pre-terminal phase. In the final logistic regression model only Midazolam was statistically significant and only at final doses of 20 mg/24hrs or over (OR 3.81 CI 1.41-10.34). Dying patients with a requirement for a high dose of Midazolam have an increased likelihood of developing death rattle. This article is protected by copyright. All rights reserved.

Forgetting to remember our experiences: People overestimate how much they will retrospect about personal events.

Science.gov (United States)

Tully, Stephanie; Meyvis, Tom

2017-12-01

People value experiences in part because of the memories they create. Yet, we find that people systematically overestimate how much they will retrospect about their experiences. This overestimation results from people focusing on their desire to retrospect about experiences, while failing to consider the experience's limited enduring accessibility in memory. Consistent with this view, we find that desirability is a stronger predictor of forecasted retrospection than it is of reported retrospection, resulting in greater overestimation when the desirability of retrospection is higher. Importantly, the desire to retrospect does not change over time. Instead, past experiences become less top-of-mind over time and, as a result, people simply forget to remember. In line with this account, our results show that obtaining physical reminders of an experience reduces the overestimation of retrospection by increasing how much people retrospect, bringing their realized retrospection more in line with their forecasts (and aspirations). We further observe that the extent to which reported retrospection falls short of forecasted retrospection reliably predicts declining satisfaction with an experience over time. Despite this potential negative consequence of retrospection falling short of expectations, we suggest that the initial overestimation itself may in fact be adaptive. This possibility and other potential implications of this work are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Pregnancy Outcomes Complicated by Preterm Premature Rupture of Membranes: Retrospective Review of Cases in Three Institutions in Kazakhstan

Directory of Open Access Journals (Sweden)

2015-06-01

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.

Adenoid cystic carcinoma (ACC) are uncommon tumors, representing about 10% to 15% of head and neck tumors. We compare the survival and control rates at our institution with those reported in the literature, and examine putative predictors of outcome. All patients registered with the tumor registry as having had ACC were identified. Demographic and survival variables were retrieved from the database. Additionally, a chart review of all patients was done to obtain specific information. Minor gland tumors were staged using the American Joint Committee on Cancer's criteria for squamous cell carcinomas in identical sites. Histopathologic variables retrieved included grade of the tumor, margins, and perineural invasion. Treatment modalities, field sizes, and radiation doses were recorded in applicable cases. An effort to retrieve archival tumor specimens for immunohistochemical analysis was undertaken. A total of 69 patients were treated for ACC from 1955 to 1999. One patient, who presented with fatal brain metastasis, was excluded from further analysis. Of the remaining 68 patients, 30 were men and 38 were women. The average age at diagnosis was 52 years, and mean follow-up was 13.2 years. Mean survival was 7.7 years. Overall survival (OS) rates at 5, 10, and 15 years were 72%, 44%, and 34%, and cause-specific survival was 83%, 71%, and 55%, respectively. Recurrence-free survival rates were 65%, 52%, and 30% at 5, 10, and 15 years, with a total of 29 of 68 (43%) eventually suffering a recurrence. Overall survival was adversely affected by advancing T and AJCC stage. Higher tumor grades were also associated with decreased OS, although the numbers compared were small. Primaries of the nasosinal region fared poorly when compared with other locations. Total recurrence-free survival, local and distant recurrence rates were distinctly better in primaries of the oral cavity/oropharynx when compared with those in other locations. Reduced distant recurrence-free survival was

Occ DEAS Assessing occupational exposure in retrospective community-based case-control studies is difficult as measured exposure data are very seldom available. The expert assessment method is considered the most accurate way to attribute exposure but it is a time consuming and expensive process and may be seen as subjective, non reproducible, and non transparent. In this paper, we describe these problems and outline our solutions as ope rationalized in a web-based software application (Occ DEAS). The novel aspects of Occ DEAS are combining all steps in the assessment into one software package; enmeshing the process of assessment into the development of questionnaires; selecting the exposure(s) of interest; specifying rules for exposure assignment; allowing manual or automatic assessments; ensuring that circumstances in which exposure is possible for an individual are highlighted for review; providing reports to ensure consistency of assessment. Development of this application has the potential to make high-quality occupational assessment more efficient and accessible for epidemiological studies

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by severe hypophosphatemia and osteomalacia. Nonspecific symptoms make the diagnosis elusive. In addition, locating the responsible tumor(s) is challenging. The aim of this study was to investigate the clinical management and outcomes of TIO. The clinical features, diagnostic procedures, treatment, and outcomes of 12 patients were reviewed retrospectively. The cohort comprised six men and six women (mean age 45.5 ± 9.9 years, range 23-61 years). The mean duration of disease was 3.7 ± 2.6 years. All patients manifested progressive bone pain, muscle weakness, and/or difficulty walking. Serum phosphorus concentrations were low in all patients (mean 0.42 ± 0.12 mmol/L). Technetium-99m octreotide scintigraphy was performed in 11 patients and showed lesions in the right distal femur, left femoral head, and right tibial plateau, respectively, in three patients. Magnetic resonance imaging (MRI) was negative for lesions in one patient. Two patients underwent biopsies that showed negative histopathology. Two patients, at 2 years and 8 months, respectively, after having negative technetium-99m octreotide studies, underwent 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (CT), which revealed lesions in the sacrum and soft tissue of the left palm, respectively. One tumor was detected by CT and MRI. Overall, lesion sites were the head (two patients, 16.7%), thoracic and lumbar region (two, 16.7%), pelvis (three, 25%), lower limbs (four, 33.3%), and upper limbs (one, 8.3%). All patients underwent surgery, and histopathology showed phosphaturic mesenchymal tumors in each. Postoperatively, serum phosphorus concentrations normalized within 2-7 days in 11 patients. With follow-ups of 1-41 months, surgery was effective in 10 patients. One patient developed local recurrence and another had metastases. Locating tumors responsible for tumor-induced osteomalacia is

The purpose of this retrospective study was to determine the clinical practices for prescribing yoked prisms, as well as to assess related patient responses, in a sample of visually-symptomatic patients having acquired brain injury (ABI). The clinical records of individuals with acquired brain injury (ABI) that were assessed for yoked prisms were reviewed retrospectively. This query resulted in 60 patient records for analysis between January 2011 and December 2012. The following diagnostic groups were analysed: homonymous hemianopsia (HH)/homonymous quadranopsia, abnormal egocentric localization (AEL) and visual neglect. HH/homonymous quadranopsia (58.3%) was the primary indication to prescribe yoked prisms, followed by visual neglect/unilateral spatial inattention (USI) (40.0%) and AEL (11.7%). The most common favourable patient responses were increased awareness of their blind visual field and improved gait, mobility and balance. The magnitude and direction of prisms prescribed were dependent upon the subjective responses in patients manifesting AEL. In contrast, base direction was dependent upon the direction of visual field loss in patients with HH/homonymous quadranopsia and visual neglect. Two-thirds of the present sample population responded favourably to the yoked prisms. The results of the present study should prove useful to clinicians for the successful prescription of yoked prisms as a treatment modality in patients presenting with the above three diagnoses.

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.

To describe the clinical characteristics of recurrent septic peritonitis in dogs. Multicenter retrospective observational study. Client-owned dogs with recurrent septic peritonitis. Three university emergency and referral hospitals. None. Medical records from 3 veterinary university teaching hospitals were reviewed and data were collected using a standardized data collection sheet for all cases of septic peritonitis during the study period (2000-2011). Forty one dogs met the inclusion criteria for recurrent peritonitis. All dogs underwent relaparotomy. The original cause of septic peritonitis in these cases included previous surgery for gastrointestinal foreign body removal (n = 26), gastrointestinal neoplasia (n = 3), gastric or duodenal ulceration (n = 3), biliary tract leakage (n = 2), and single instance for each of the following: penetrating foreign body, hernia strangulation, intussusception, mesenteric volvulus, infection of the laparotomy incision, prostatic abscess, and trauma. Eighteen animals survived to discharge. There was no difference detected between survivors and nonsurvivors with recurrent peritonitis in terms of inciting cause, serum albumin concentration, surgical management, or provision of appropriate initial antimicrobials. The survival rate for dogs having recurrent peritonitis was 43.9% (18/41 dogs). This retrospective study did not identify any significant prognostic indicators for dogs with recurrent peritonitis and that the mortality rate for dogs having more than one surgery for septic peritonitis is similar to that reported for a single surgery for septic peritonitis. ©Veterinary Emergency and Critical Care Society 2015.

Full Text Available Objective: To determine if pharmacist-provided medication therapy management (MTM improves medication adherence in Medicare patients. A secondary objective is to compare the total monthly cost of a patient’s prescription medication regimen 6 months before and 6 months following a comprehensive medication review (CMR. Design: Retrospective analysis of medication adherence, pre-post comparison. Setting: Three independent pharmacies in North Carolina. Patients: 97 Medicare Part D beneficiaries with one or more chronic disease states who participated in a comprehensive medication review (CMR. Intervention: MTM services provided by community pharmacists. Main outcome measure: Change in adherence as measured by the proportion of days covered (PDC and change in medication costs for patients and third party payers. Results: Patients were adherent to chronic disease-state medications before and after MTM (PDC≥ 0.8. Overall, change in mean adherence before and after MTM did not change significantly (0.87 and 0.88, respectively; p = 0.43. However, patients taking medications for cholesterol management, GERD, thyroid and BPH demonstrated improved adherence following a CMR. No change in adherence was noted for patients using antihypertensives and antidiabetic agents. Average total chronic disease-state medication costs for participants were reduced from $210.74 to $193.63 (p=0.08 following the comprehensive medication review. Total costs for patient and third party payers decreased from patients prescribed antilipemics, antihypertensives, GERD and thyroid disorders following a CMR. Conclusions: Pharmacist-provided MTM services were effective at improving medication adherence for some patients managed with chronic medications. Pharmacist-provided MTM services also were effective in decreasing total medication costs.

Grand Challenges for international health and development initiatives have received substantial funding to tackle unsolved problems; however, evidence of their effectiveness in achieving change is lacking. A theory of change may provide a useful tool to track progress towards desired outcomes. The Saving Lives at Birth partnership aims to address inequities in maternal-newborn survival through the provision of strategic investments for the development, testing and transition-to-scale of ground-breaking prevention and treatment approaches with the potential to leapfrog conventional healthcare approaches in low resource settings. We aimed to develop a theory of change and impact framework with prioritised metrics to map the initiative's contribution towards overall goals, and to measure progress towards improved outcomes around the time of birth. A theory of change and impact framework was developed retrospectively, drawing on expertise across the partnership and stakeholders. This included a document and literature review, and wide consultation, with feedback from stakeholders at all stages. Possible indicators were reviewed from global maternal-newborn health-related partner initiatives, priority indicator lists, and project indicators from current innovators. These indicators were scored across five domains to prioritise those most relevant and feasible for Saving Lives at Birth. These results informed the identification of the prioritised metrics for the initiative. The pathway to scale through Saving Lives at Birth is articulated through a theory of change and impact framework, which also highlight the roles of different actors involved in the programme. A prioritised metrics toolkit, including ten core impact indicators and five additional process indicators, complement the theory of change. The retrospective nature of this development enabled structured reflection of the program mechanics, allowing for inclusion of learning from the first four rounds of the

Full Text Available Remembering the emotions we have experienced in the past is the core of one´s unique life-experience. However, there are many factors, both at the state and trait level that can affect the way past feelings are seen. The main aim of the current study was to examine the impact of individual differences on systematic biases in retrospective ratings compared to the momentary experience of basic emotions such as sadness, fear, happiness, and anger. To this end, an experience sampling study across two weeks was conducted using a younger and an older age-group; the experience of momentary emotions was assessed on 7 randomly determined occasions per day, the retrospective ratings being collected at the end of each day about that day, as well as at the end of the study about the previous two weeks. The results indicated that age and daily tiredness have significant effects on retrospective emotion ratings over a one-day period (state level, enhancing the retrospective ratings of negative emotions and decreasing the ratings of felt happiness. Whereas personality traits influence the more long-term emotion experience (trait level, with all Big Five personality traits having selective impact on retrospective emotion ratings of fear, sadness, happiness, and anger. Findings provide further evidence about the systematic biases in retrospective emotion ratings, suggesting that, although retrospective ratings are based on momentary experience, daily tiredness and personality traits systematically influence the way in which past feelings are seen.

Remembering the emotions we have experienced in the past is the core of one's unique life-experience. However, there are many factors, both at the state and trait level that can affect the way past feelings are seen. The main aim of the current study was to examine the impact of individual differences on systematic biases in retrospective ratings compared to the momentary experience of basic emotions such as sadness, fear, happiness, and anger. To this end, an experience sampling study across 2 weeks was conducted using a younger and an older age-group; the experience of momentary emotions was assessed on 7 randomly determined occasions per day, the retrospective ratings being collected at the end of each day about that day, as well as at the end of the study about the previous 2 weeks. The results indicated that age and daily tiredness have significant effects on retrospective emotion ratings over a 1-day period (state level), enhancing the retrospective ratings of negative emotions and decreasing the ratings of felt happiness. Whereas personality traits influence the more long-term emotion experience (trait level), with all Big Five personality traits having selective impact on retrospective emotion ratings of fear, sadness, happiness, and anger. Findings provide further evidence about the systematic biases in retrospective emotion ratings, suggesting that, although retrospective ratings are based on momentary experience, daily tiredness and personality traits systematically influence the way in which past feelings are seen.

Full Text Available Background. Colorectal cancer (CRC is a growing public health concern with increasing rates in countries with previously known low incidence. This study determined pattern and distribution of CRC in Tanzania and identified hot spots in case distribution. Methods. A retrospective chart audit reviewed hospital registers and patient files from two national institutions. Descriptive statistics, Chi square (χ2 tests, and regression analyses were employed and augmented by data visualization to display risk variable differences. Results. CRC cases increased sixfold in the last decade in Tanzania. There was a 1.5% decrease in incidences levels of rectal cancer and 2% increase for colon cancer every year from 2005 to 2015. Nearly half of patients listed Dar es Salaam as their primary residence. CRC was equally distributed between males (50.06% and females (49.94%, although gender likelihood of diagnosis type (i.e., rectal or colon was significantly different (P=0.027. More than 60% of patients were between 40 and 69 years. Conclusions. Age (P=0.0183 and time (P=0.004 but not gender (P=0.0864 were significantly associated with rectal cancer in a retrospective study in Tanzania. Gender (P=0.0405, age (P=0.0015, and time (P=0.0075 were all significantly associated with colon cancer in this study. This retrospective study found that colon cancer is more prevalent among males at a relatively younger age than rectal cancer. Further, our study showed that although more patients were diagnosed with rectal cancer, the trend has shown that colon cancer is increasing at a faster rate.

Full Text Available Objectives: To report cases of idiopathic osteosclerosis (IO, to review the literature on the subject, and to discuss its main characteristics, diagnosis, differential diagnosis, and treatment. Material and methods: Retrospective analysis of 354 panoramic radiographs, searching for IO, its size, shape, location, and noting patients’ demographic information. Literature review used Medline and Lilacs databases and the terms idiopathic osteosclerosis OR bone sclerosis OR dense bone island AND jaws. Results: IO was identified in 5.6% of the radiographs (n=20 patients, 22 foci. Patients were healthy, with an age ranging from 5 to 51 years (mean=29.8, with male-female ratio of 3:2. IOs were found mainly in the premolar/molar region, at root apices, between roots, away from the teeth, laterally to the tooth, and in edentulous areas. The distribution between right and left sides of the jaw was equal for the 22 foci, with only one case in the maxilla. IOs were localized, well-defined, radiopaque, mostly round or ovoid in shape, but sometimes irregular. In some cases, IOs were similar to condensing osteitis, but differential diagnosis also considered complex odontoma, focal cemento-osseous dysplasia, and residual roots. Twenty studies on the topic were reviewed. Conclusions: Incidence of IO in the Brazilian sample was 5.6%, with age ranging from 5 to 51 years (mean=29.8, and male-female ratio of 3:2. The radiopacities occurred in different locations, with significant prevalence in the mandible. The findings and the literature review corroborate the hypothesis that IO should be considered developmental variation of normal bone that does not require treatment.

Objectives

2011-01-01

Full Text Available Objectives The purpose of this retrospective study was to evaluate the success rate of intentionally replanted mandibular second molar with C-shaped canal configurations and to access the impact of preoperative periapical lesion on the success of intentional replantation procedure. Materials and Methods This retrospective chart review study evaluated 52 intentionally replanted mandibular second molar teeth treated at Seoul National University Dental Hospital Department of Conservative Dentistry from January 2005 to December 2007. Seventeen teeth were lost for the follow-up, and another 6 teeth did not meet inclusion criteria of C-shaped root canal configurations. Healing outcome such as success, uncertain healing, and failure after follow-up was evaluated by clinical criteria and radiographs. Results The overall success rate was 72.4% for the 29 intentionally replanted C-shaped mandibular second molars. The success rate of replanted teeth with preoperative periapical lesions was similar to that of replanted teeth which have no periapical lesions. Conclusions Therefore, root canal treatment failure on C-shaped mandibular second molar can be predictably treated by intentional replantation regardless of the presence of periapical lesion.

To identify factors contributing to the occurrence of unintended pregnancies after Essure sterilization in the Netherlands. Even though Essure is a permanent method of contraception, unintended pregnancies have been reported. Retrospective case series analysis. Not applicable. Thirty-five pregnancies were reported in the Netherlands after Essure sterilization from 2002 through 2014 out of 27,346 placements. Data regarding Essure placement procedure, confirmation tests, and pregnancy outcome of the reported cases were obtained and analyzed to identify a possible cause of failure. Four causes of failure were identified: perforation (n = 10), expulsion (n = 7), unilateral placement (n = 7), and luteal pregnancy (n = 2). The occurrence of most pregnancies was related to physician noncompliance (n = 14). The other cases were associated with patient noncompliance (n = 5) or misinterpretation of the confirmation test (n = 9). Most pregnancies occurred within the first 24 months after the 3-month confirmation test (n = 23). The results of this study show that the incidence of pregnancies after Essure sterilization is low. Most pregnancies were related to incorrect positioning of a device or unilateral placement, and seem therefore preventable. Unilateral placement without prior history of salpingectomy should always be considered as unsuccessful sterilization. Furthermore, interpretation of the confirmation tests should be done by trained physicians, and with caution. We want to emphasize the importance of strictly adhering to placement and follow-up protocols. Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc.

Nonunion is an uncommon complication after mandibular fractures. The purpose of this investigation was to compare outcomes of patients with mandibular fracture nonunion who were treated with a 1- versus 2-stage approach and propose a pragmatic treatment algorithm for surgical management based on preoperative characteristics. The authors conducted a retrospective study consisting of patients who presented to 2 level 1 trauma centers for the management of mandibular fracture nonunion over a 10-year period. The primary predictor variable was 1- versus 2-stage treatment. Outcomes were examined to propose a treatment algorithm. Eighteen patients were included in the study. The sample's mean age was 44.0 ± 19.3 years and most were men (88.9%). Mandibular angle and body accounted for 77.8% of cases. A single-stage approach was used in 13 patients (72.2%). Bone grafts or vascularized bone flaps were required in 13 patients (72.2%). Patients who required 2-stage treatments had intraoral soft tissue defects. Mean length of follow-up was 13.3 ± 20.4 months. All patients achieved bony union, with complications occurring in 5 patients (27.8%). The authors' 10-year experience was used to formulate a treatment algorithm based on bony defect size and soft tissue status, which can be used to inform optimal surgical management. Nonunion of mandibular fractures is an infrequent and complex condition requiring careful and deliberate surgical management. A single-stage approach is appropriate in most cases and does not negatively affect outcomes. Bony defect size and soft tissue status are essential parameters for determining the approach and timing of reconstruction. Copyright © 2018 American Association of Oral and Maxillofacial Surgeons.

Ongoing refractory status epilepticus is associated with significant morbidity and mortality. Therapeutic coma induction with midazolam, thiopentone, phenobarbitone or propofol is indicated when conventional antiepileptics fail to abort seizure. Of these, the most extensively studied is midazolam. Amongst the remaining three, phenobarbitone has the most favourable pharmacological profile, but has not been studied adequately, more so in the pediatric age group. The current retrospective case records analysis is an attempt to describe use of phenobarbitone coma in pediatric refractory status epilepticus. Case records of patients, admitted with status epilepticus to the pediatric inpatient services of a tertiary care teaching hospital of North India between January 2014 and December 2016 were reviewed. Those with refractory status epilepticus who failed to respond to midaolam infusion and phenobarbitone coma was used were included for analysis. Overall, 108 children presented in status, of which 34 developed refractory status epilepticus. Of these 34, 21 responded to midazolam infusion and in 13 high dose phenobarbitone coma following a standardised protocol was used. Amongst these 13 (8 males and 5 females, median age 6 years, IQR: 2.5-9.5), 12 responded and 1 succumbed. The median time to clinical seizure resolution and desired electroencephalographic changes post phenobarbitone initiation were 16 (IQR: 12-25) and 72 h (IQR: 48-120) respectively. High dose phenobarbitone appears to be an effective therapeutic modality in pediatric refractory status epilepticus. The current study provides a protocol for its use which can be validated in future studies with larger sample size. Copyright © 2018 The Japanese Society of Child Neurology.

Full Text Available Objective. We aimed to systematically review the literature dealing with the epidemiology, classification, clinical course, diagnosis and treatment of thymoma. Material and methods. We reviewed retrospective and prospective randomized trials using Medline and Elibrary databases. Results. The classification system, prognostic factors, paraneoplastic syndromes and their incidence in patients with thyoma were described. The diagnostic value of computed tomography, magnetic resonance imaging and positron emission tomography was evaluated and the methods of morphologic verification were described. The main attention was paid to multimodality treatment of thymoma, including surgery and intraoperative radiotherapy. Conclusion. Thymoma is a rare tumor. The accumulation of long-term follow-up results prompted the changes in clinical management of thymoma. Predisposition to late recurrence even after radical surgery determined multimodality treatment strategies.

The Sense of Agency in Autism Spectrum Disorders: a Dissociation between Prospective and Retrospective Mechanisms?

Directory of Open Access Journals (Sweden)

Tiziana eZalla

2015-09-01

Full Text Available While a large number of studies have reported impairments in social and interpersonal abilities in individuals with autism spectrum disorder (ASD, relatively few studies have focused on self-related knowledge in this population. One of the processes implicated in the physical dimension of the Self is the sense of agency (SoA, i.e., the experience of initiating and controlling one’s own actions and producing desired changes in the world via these actions. So far, the few studies investigating SoA in ASD have reported contrasting results, with some showing spared, others impaired SoA. Here, we review the existing literature and suggest that the distinction between prospective and retrospective mechanisms of the SoA might help reconcile the existing findings. In the light of a multi-componential model of SoA, we propose the view that a specific impairment at the level of prospective mechanisms acting on internal agency signals (i.e., the intention, action selection, or command produced to achieve the goal may be responsible for the reduced SoA in ASD, along with spared retrospective mechanisms. Future research should shed light on the impact of abnormal SoA on social and self-related dysfunctions in ASD.

Full Text Available Abstract Background Endoscopic biliary drainage of hilar cholangiocarcinoma is controversial with respect to the optimal types of stents and the extent of drainage. This study evaluated endoscopic palliation in patients with hilar cholangiocarcinoma using self-expandable metallic stents (SEMS and plastic stents (PS.We also compared unilateral and bilateral stent placement according to the Bismuth classification. Methods Data on 480 patients receiving endoscopic biliary drainage for hilar cholangiocarcinoma between September 1995 and December 2010 were retrospectively reviewed to evaluate the following outcome parameters: technical success (TS, functional success (FS, early and late complications, stent patency and survival. Patients were followed from stent insertion until death or stent occlusion. Patients were divided into 3 groups according to the Bismuth classification (Group 1, type I; Group 2, type II; Group 3, type > III. Results The initial stent insertion was successful in 450 (93.8% patients. TS was achieved in 204 (88.3% patients treated with PS and in 246 (98.8% patients palliated with SEMS (p P P  Conclusions SEMS insertion for the palliation of hilar cholangiocarcinoma offers higher technical and clinical success rates in the ITT analysis as well as lower complication rates and a superior cumulative stent patency when compared with PS placement in all Bismuth classifications. The cumulative patency of bilateral SEMS or PS stents was significantly higher than that of unilateral SEMS or PS stents, with lower occlusion rates in Bismuth II patients.

To determine the influence of preoperative septic peritonitis (PSP) and stapled versus hand-sewn anastomoses on the dehiscence of intestinal resection and anastomosis (IRA). We hypothesized that the incidence of IRA dehiscence would be greater (1) when performed with PSP and (2) for hand-sewn anastomoses. Retrospective. Client-owned dogs at Michigan State University Veterinary Teaching Hospital. Records of dogs surviving 72 hours after IRAs between 2003 and 2013 were reviewed for age, gender, neuter status, weight, presence of PSP, preoperative albumin, IRA indication and location, anastomotic technique, suture type, postoperative dehiscence and timing, duration of hospitalization, last follow-up, and other complications. Univariate logistic regression and chi-square analysis were used to screen prognostic factors; factors with P dogs fulfilled the inclusion criteria. Dehiscence was diagnosed in 11.4% cases, 6.6% without PSP, and 21.1% with PSP (P = .01). Indication for IRA did not influence the risk of dehiscence. No association was detected between anastomotic technique and IRA dehiscence in dogs without PSP (stapled 4.2%, hand-sewn 8.1%); however, stapled anastomoses were less likely to dehisce in dogs with PSP (stapled 9.7%, hand-sewn 28.9%). Risk factors for dehiscence included PSP (P = .005) and hand-sewn technique (P = .02). Our results confirmed that PSP is a risk factor for dehiscence of IRA and suggest that patients with PSP may be a unique surgical population, in which stapling may be preferred over hand-sewn anastomoses after enterectomies. © 2017 The American College of Veterinary Surgeons.

Teleconference versus face-to-face scientific peer review of grant application: effects on review outcomes.

Directory of Open Access Journals (Sweden)

Stephen A Gallo

Full Text Available Teleconferencing as a setting for scientific peer review is an attractive option for funding agencies, given the substantial environmental and cost savings. Despite this, there is a paucity of published data validating teleconference-based peer review compared to the face-to-face process. Our aim was to conduct a retrospective analysis of scientific peer review data to investigate whether review setting has an effect on review process and outcome measures. We analyzed reviewer scoring data from a research program that had recently modified the review setting from face-to-face to a teleconference format with minimal changes to the overall review procedures. This analysis included approximately 1600 applications over a 4-year period: two years of face-to-face panel meetings compared to two years of teleconference meetings. The average overall scientific merit scores, score distribution, standard deviations and reviewer inter-rater reliability statistics were measured, as well as reviewer demographics and length of time discussing applications. The data indicate that few differences are evident between face-to-face and teleconference settings with regard to average overall scientific merit score, scoring distribution, standard deviation, reviewer demographics or inter-rater reliability. However, some difference was found in the discussion time. These findings suggest that most review outcome measures are unaffected by review setting, which would support the trend of using teleconference reviews rather than face-to-face meetings. However, further studies are needed to assess any correlations among discussion time, application funding and the productivity of funded research projects.

Teleconferencing as a setting for scientific peer review is an attractive option for funding agencies, given the substantial environmental and cost savings. Despite this, there is a paucity of published data validating teleconference-based peer review compared to the face-to-face process.

Vaginal penetration phobia is a common and distressing problem world.wide. It interferes with vaginal penetrative sexual relations, and leads to unconsummated marriage (UCM). This problem may be heightened in Arab women, due to cultural taboos about pain and bleeding, that may be associated with the first coital experience after marriage. Data about this problem is scarce in Arab societies. The aim of this study was to evaluate the response of these women and their husbands to an individualized, psychotherapeutic assessment and treatment to resolve this problem. Retrospective descriptive in a general gynecology community setting over a 6-year period. The study involved a retrospective sequential cohort of 100 Arab couples with UCM due to the woman's VPP. They were evaluated by a female gynecologist in out patient clinics. Data was collected through chart review, and telephone interviews. Final analysis was performed on 100 Arab couples, who satisfied the inclusion criteria. They were followed up to assess their response to an individualized, structured treatment protocol. The treatment combined sex education with systematic desensitization, targeting fear and anxiety as.sociated with vaginal penetration. A total of 96% of the studied group had a successful outcome after an average of 4 sessions. Penetrative intercourse was reported by the tolerance of these women; further pregnancy was achieved in 77.8 % of the infertile couples. Insufficient knowledge of sexual intercourse is a major contributor to the development of VPP in the sampled population. It appears that they respond well to an individualized, structured treatment protocol as described by Hawten 1985 (regardless of other risk factors associated with vaginismus).

A Retrospective Analysis of Ruptured Breast Implants

2014-11-01

Full Text Available BackgroundRupture is an important complication of breast implants. Before cohesive gel silicone implants, rupture rates of both saline and silicone breast implants were over 10%. Through an analysis of ruptured implants, we can determine the various factors related to ruptured implants.MethodsWe performed a retrospective review of 72 implants that were removed for implant rupture between 2005 and 2014 at a single institution. The following data were collected: type of implants (saline or silicone, duration of implantation, type of implant shell, degree of capsular contracture, associated symptoms, cause of rupture, diagnostic tools, and management.ResultsForty-five Saline implants and 27 silicone implants were used. Rupture was diagnosed at a mean of 5.6 and 12 years after insertion of saline and silicone implants, respectively. There was no association between shell type and risk of rupture. Spontaneous was the most common reason for the rupture. Rupture management was implant change (39 case, microfat graft (2 case, removal only (14 case, and follow-up loss (17 case.ConclusionsSaline implants have a shorter average duration of rupture, but diagnosis is easier and safer, leading to fewer complications. Previous-generation silicone implants required frequent follow-up observation, and it is recommended that they be changed to a cohesive gel implant before hidden rupture occurs.

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 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.

ECG-triggered cinematographic studies of the cardiovascular system are hampered by several technical restrictions such as the inability to image end-diastole, ghosting, varying signal intensity, and phase contributions from eddy currents. Retrospective gating may solve these problems, but involves...... of flow pulses. However, by reducing the time window retrospectively gated flow measurements were in good agreement with those that are ECG triggered. When fulfilling the demand of a narrow time window for interpolation, retrospective gating offers several advantages in MR velocity mapping....

Following a nuclear accident or a terror attack involving the dispersal of radioactive material, radiation dose assessment to first responders and the members of the public is essential. This information may be used by medical personnel to decide whether to refer the exposed individual for medical treatment or not. Few people, if any, will be wearing standard dosimeters at the exposure scene, so the need for a retrospective assessment of the radiation dose is an acute necessity. Previously developed methods for retrospective dosimetry (RD) have suggested various types of materials such as tiles, bricks, CDs, electronic components, mobile phones, electron paramagnetic resonance of tooth enamel, hair, nails, biological dosimetry techniques etc. These techniques involve significant disadvantages such as: the long time required to prepare the samples for measurement the considerable expense of the measuring equipment, invasive procedure and others. The need for an RD technique which will be fast, inexpensive, reliable, non-invasive and, if possible, portable, remains an on-going challenge. The ideal retrospective dosimeter must fulfill the following basic criteria: a) Availability in the contaminated area, b) Adequate dose measurement capability in the relevant range of dose levels, c) Negligible or known fading between exposure and measurement

Full Text Available Objective: To compare pre- and post-therapy symptom scores reported on the National Institute of Health Chronic Prostatitis Symptom Index (NIHCPSI after trans-rectal antibiotic injections therapy for men suffering from chronic prostatitis. Materials and methods: Retrospective analysis of NIHCPSI symptom scores obtained from chart reviews of 77 treated males suffering from chronic prostatitis before and after trans rectal injections for the treatment of chronic prostatitis. Results: Most patients reported a 40% to 60% improvement in symptom scores. In subgroups comparing scores in patients with less than 5 injections, the improvement was less than in patients who received 10 or more injections. Patients’ responses after a shorter (3 months follow up showed better pain scores than patient’s scores after longer, over one-year or more, follow- up periods. Conclusion: Our findings show that direct antibiotic injection for chronic prostatitis is a viable addition to standard therapies. Improvements in symptom scores are long lasting. Discomfort is minimal and side effects are rare and avoidable

2013-01-01

Objective: To explore the epidemiology of burn injuries in Zahedan, Southeastern Iran. Methods: A retrospective review of 730 medical records, of burnt patients, for a period of two years was done. Pre-designed data recording forms were used to collect data. The SPSS-15 was used to analyze data. Results: Overall, 713 medical records were analyzed: two-thirds (62.0%) were fire-related and one-third related to scalds (33.1%). Intentional self-harm injuries accounted for 14.3% of all admissions. A significant difference existed between patients' age or sex and the causes of burns (P<0.001). Burns more than 60% closely correlated with death rate and hospital stay (P<0.001). Conclusion: Lack of the necessary, socio-economic infrastructure, language and cultural barriers, low level of literacy, flammability of women's clothes and unsafe application/design of stove and heaters are likely to contribute to the high frequency of burn injuries in this area.

Headache is a common symptom, that can be extremely disabling, affecting 26 million of patients only in Italy. ICHD-II has reported two categories: "primary headaches" and "secondary headaches". Temporomandibular joint disorders can lead to a secondary headaches. We want to evaluate the prevalence and clinical features of headache among a series of patients having temporomandibular joint disorders and we illustrate the evolution of headache following medical treatament of temporomandibular joint (TMJ) disorders. This is a retrospective study carried out on chart review of 426 consecutive patients with various degrees of temporomandibular disorders and treated with medical devices from 2007 to 2011. Headache was reported by 73 patients (17.14%). Headache was observed in 36 of 51 patients with lock and in 32 out of 130 patients with mandibular deflections (Table I). The remaining 5 patients with headache had articular noise. Headache is not a rare finding in a population with temporomandibular dysfunctions and is more often a tension-type rather than trigeminal headache.

This retrospective study evaluated the outcomes of dogs with macroscopic pulmonary metastasis of appendicular osteosarcoma (OSA) treated with toceranib. Medical records of 20 dogs with macroscopic pulmonary metastasis of OSA that received toceranib were reviewed. The median dose and duration of toceranib administration were 2.52 mg/kg (range: 2.12 to 2.72 mg/kg) and 60 days (range: 17 to 231 days). The median progression free survival (PFS) and overall survival (OS) were 36 days (range: 17 to 231 days) and 90 days (range: 17 to 433 days), respectively. The clinical benefit rate was 10% (2/20; 1 partial response and 1 stable disease). The longest length of initial pulmonary nodules had significant impact on both PFS ( P = 0.01) and OS ( P = 0.02). The prognosis for dogs with metastatic OSA was poor with only 10% of dogs showing clinical benefit from toceranib. These results suggest that toceranib may not improve outcome in dogs with macroscopic pulmonary metastasis of OSA.

Full Text Available The aim of this study is to systematically review the literature with regards to surgical treatment of patients with hip joint osteochondromas, and to report our surgical management of three paediatric patients who had femoral neck or acetabular osteochondromas in association with acetabular dysplasia. We performed a systematic review using PubMed and Embase databases for all studies that reported surgical treatments for patients with peritrochanteric or acetabular osteochondroma with or without acetabular dysplasia. We also retrospectively reviewed three patients who were diagnosed with a hip osteochondroma in association with actetabular dysplasia. These patients were known to have hereditary multiple exostoses (HME. The systematic review revealed 21 studies that met our inclusion criteria. All studies were case reports and retrospective in nature and failed to conclude a uniform treatment plan. The three reported cases illustrate successful excision of hip osteochondromas and treatment of acetabular dysplasia. Early excision of hip osteochondromas might prevent acetabular dysplasia in HME patients. Routine radiographic pelvic survey at the time of diagnosis of HME is recommended for early detection of hip osteochondromas and acetabular dysplasia in these children.

Optically stimulated luminescence (OSL) of dental enamel for retrospective assessment of radiation exposure

International Nuclear Information System (INIS)

Yukihara, E.G.; Mittani, J.; McKeever, S.W.S.; Simon, S.L.

2007-01-01

This paper briefly reviews the optically stimulated luminescence (OSL) properties of dental enamel and discusses the potential and challenges of OSL for filling the technology gap in biodosimetry required for medical triage following a radiological/nuclear accident or terrorist event. The OSL technique uses light to stimulate a radiation-induced luminescence signal from materials previously exposed to ionizing radiation. This luminescence originates from radiation-induced defects in insulating crystals and is proportional to the absorbed dose of ionizing radiation. In our research conducted to date, we focused on fundamental investigations of the OSL properties of dental enamel using extracted teeth and tabletop OSL readers. The objective was to obtain information to support the development of the necessary instrumentation for retrospective dosimetry using dental enamel in laboratory, or for in situ and non-invasive accident dosimetry using dental enamel in emergency triage. An OSL signal from human dental enamel was detected using blue, green, or IR stimulation. Blue/green stimulation associated with UV emission detection seems to be the most appropriate combination in the sense that there is no signal from un-irradiated samples and the shape of the OSL decay is clear. Improvements in the minimum detection level were achieved by incorporating an ellipsoidal mirror in the OSL system to maximize light collection. Other possibilities to improve the sensitivity and research steps necessary to establish the feasibility of the technique for retrospective assessment of radiation exposure are also discussed

Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 2012. In the UBC group (352 cases) humerus, femur and calcaneus were found to be the most common sites, while acetabulum, scapula, scaphoid, lunatum, metacarpals, metatarsals, toe phalanges and ulna each accounted for less than 1%. In the ABC group (99 cases) the most common sites of involvement were femur, humerus and tibia, while finger phalanges, ilium, acetabulum, pubis, calcaneus, cuboid, and toe phalanges each accounted for only 1%. The differential diagnosis of cystic bone lesions should include both UBC and ABC. Pain complaints plead for the latter, except in case of fracture.

Pelvic pain is a common complaint, and management of it is often difficult. We sought to evaluate the utility of magnetic resonance imaging (MRI) in the diagnosis of male pelvic pain. Though MRIs are commonly ordered to evaluate pelvic pain, there are very few studies obtaining the efficacy of pelvic MRI in determining a definitive diagnosis. The primary aim of our study was to evaluate the clinical utility of pelvic MRI for a diagnosis code that included pain. After receiving institutional review board approval, a retrospective study was performed of all pelvic MRIs completed at our institution from January 2, 2010 to December 31, 2014. These were further delineated into ordering providers by specialty and urology-specific International Classification of Diseases, Ninth Revision (ICD-9) code diagnoses (male pelvic pain, prostatitis, groin pain, scrotal pain, testicular pain, and penile pain). Clinical utility was defined as positive if MRI findings resulted in a change in management. Subanalysis was performed on patients with an ICD-9 co-diagnosis of previous oncologic concern. A total of 2,643 pelvic MRIs were ordered at our institution over a 5-year period. Of these, 597 pelvic MRIs (23%) were ordered for a diagnosis code that included pain (hip pain, rectal pain, joint pain, penile pain, scrotal pain, male pelvic pain and orchitis). Total utility for MRIs to find anatomic abnormalities potentially responsible for the present pain was 34% (205/597). When ordered by urologic providers, utility was 23%. Oncologists represented the highest positivity rate at 57%. Chronic pelvic pain is a multispecialty complaint that is difficult to treat. We were surprised to find the large number of both specialists and generalists invested in the management of pelvic pain. The increasing availability of MRI technology makes it a likely candidate to test for a clinically significant anatomic reason for pain. Though MRI is a test with minimal adverse effect and no increased risk

Spinal pain in the paediatric population is a significant health issue, with an increasing prevalence as they age. Paediatric patients attend for chiropractor care for spinal pain, yet, there is a paucity of quality evidence to guide the practitioner with respect to appropriate care planning. A retrospective chart review was used to describe chiropractic management of paediatric neck pain. Two researchers abstracted data from 50 clinical files that met inclusion criteria from a general practice chiropractic office in the Greater Toronto Area, Canada. Data were entered into SPSS 15 and descriptively analyzed. Fifty paediatric neck pain patient files were analysed. Patients' age ranged between 6 and 18 years (mean 13 years). Most (98%) were diagnosed with Grade I-II mechanical neck pain. Treatment frequency averaged 5 visits over 19 days; with spinal manipulative therapy used in 96% of patients. Significant improvement was recorded in 96% of the files. No adverse events were documented. Paediatric mechanical neck pain appears to be successfully managed by chiropractic care. Spinal manipulative therapy appears to benefit paediatric mechanical neck pain resulting from day-today activities with no reported serious adverse events. Results can be used to inform clinical trials assessing effectiveness of manual therapy in managing paediatric mechanical neck pain.

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.

2015-01-01

Optically stimulated luminescence (OSL) was used to test different kinds of desiccants for their potential use in retrospective dosimetry. Desiccants are used for the purpose of absorbing liquids and can be found in a number of items which may be found in the immediate environment of a person, including hand bags, drug packages, and the vehicles of rescue service teams. Any material exhibiting OSL properties suitable for retrospective dosimetry is a useful addition to the existing dosimetry system available in emergency preparedness. Eleven kinds of desiccants were investigated in order to obtain an overview of the fundamental OSL properties necessary for retrospective dosimetry. Measurements were made using a Risø TL/OSL reader and irradiations were achieved with the 90 Sr/ 90 Y source incorporated in the reader. Several of the desiccants exhibited promising properties as retrospective dosemeters. Some of the materials exhibited a strong as-received signal, i.e. without any laboratory irradiation, but the origin of this signal has not yet been established. The minimum detectable dose ranged from 8 to 450 mGy for ten of the materials and for one material (consisting of natural clay) the minimum detectable dose was 1.8 Gy. - Highlights: • Desiccants can be used as fortuitous dosemeters using OSL. • The minimum detectable dose for processed desiccants range from 8 to 450 mGy. • The minimum detectable dose for natural clay was 1.8 Gy

To determine the pattern of occurrence of mandibular fractures in the pediatric population in Portugal. This retrospective study reviews the records of patients 18 years of age or younger from the 10-year period 1993 to 2002. Age, gender, anatomic site, cause of the accident, weekly and monthly variation, location and type of fractures, presence and location of associated injuries, treatment methods, and complications were reviewed. During this 10-year period, 521 patients with 681 mandibular fractures were treated. Motor-vehicle accident (MVA) was the most common (53.9% patients) cause of fracture. Almost half of the patients (48.8%) were in the oldest age group (16 to 18 years old). The condyle of the mandible was involved in 31.0% of the fractures. Maxillomandibular (MMF) fixation was used in 534 (78.4%) fractures. Overall mortality in this series was 0.6% (3 patients); mortality was caused by multiple traumas, mainly head trauma. There is a need to reinforce legislation aimed to prevent MVA and the total enforcement of existing laws to reduce maxillofacial injuries among children and adolescents.

In this study, we evaluated the ability of the PARTNERS HF criteria to detect initial decompensation in a population of moderate heart failure patients under remote monitoring. Methods We retrospectively applied the PARTNERS HF criteria to 1860 transmissions from 104 patients (median follow up 21 months; range 1-67 months), who were enrolled in our programme of telemedicine after cardiac resynchronisation therapy. We tested the ability of a score based on these criteria to predict any acute clinical decompensation occurring in the 15 days following a transmission. Results In 441 cases, acute heart failure was diagnosed after the index transmission. The area under the curve (AUC) of the score for the diagnosis of acute decompensation was 0.752 (confidence interval (CI) 95% 0.728-0.777). The best score cut-off was consistent with the results of PARTNERS HF: with a score ≥2, sensitivity was 75% and specificity 68%. The odds ratio for events was 6.24 (CI 95% 4.90-7.95; p < 0.001). Conclusions When retrospectively applied to remote monitoring transmissions and arranged in a score, PARTNERS HF criteria could identify HF patients who subsequently developed acute decompensation. These results warrant prospective studies applying PARTNERS HF criteria to remote monitoring.

Endemic goitre is a major concern in many parts of the world, including Southeast Asia. Goitrous thyroid lesion is postulated as a precursor lesion to thyroid cancer (TC). This paper reviews the prevalence rates and characteristics of TC among cases of goitrous thyroid-swelling in different parts of Malaysia and Myanmar. Recorded data from hospital-based retrospective studies of thyroid cases, whose study periods ranged from three to 11 years, were analysed. These included research findings from the author's publications as well as other published review articles of retrospective analyses. The incidence of TC varies among gender, age, race/ethnicity and histological type. There appears to be a higher rate of occurrence among females aged 21-60 years. Papillary thyroid carcinoma is the more common histological type compared to follicular cancer. This review also presents a descriptive analysis and discussion on studies conducted in other countries. Further exploration is warranted in order to uncover the possible risk factors for the rising incidence of TC.

Purpose: To characterize the patient population and treatment outcomes in patients with Retinoblastoma (RB) referred for External Beam Orbital Radiotherapy (EBORT) to King Faisal Specialist Hospital and Research Centre (KFSH and RC), Riyadh, Saudi Arabia from 1976 to 1993. Methods and Materials: A retrospective study of 120 patients with RB affecting a total of 192 eyes. Patients were divided into three groups. Group A are 60 patients (64 eyes) treated with EBORT to the intact eye to preserve vision. Reese-Ellsworth (RE) Staging was: 1: 12%; 2: 10%; 3: 12%; 4: 23%; and 5: 43%. Twenty-eight patients (47%) also received Vincristine, Adriamycin, and Cyclophosphamide chemotherapy (C/T). Mean follow-up, per patient, was 48.5 months. Standard treatment until 1992 was 45 Gy in 12 fractions of 3.75 Gy, three times weekly over 18 days. Assuming the α/β ratio for early effects and tumor control at 10, Tk = 21 days, T pot = 5 days, then the Biological Equivalent Dose (BED) was 62 Gy 10 for early effects, and 101 Gy 3 for late effects. Group B are 28 patients (28 eyes) treated for curative intent with EBORT to the orbit for locally advanced disease, usually after enucleation (24 eyes). Nineteen patients (83%) also had C/T. Mean follow-up was 22.6 months. Group C are 37 patients with advanced disease treated with radiotherapy for palliation. Seventeen (46%) also received C/T. Mean follow-up was 11.7 months. Results: Group A-following EBORT useful vision was retained in RE Stage 1 to 5: 7 of 7, 6 of 6, 4 of 8, 10 of 15, and 7 of 28 eyes, respectively. There was no significant difference between patients who received adjuvant chemotherapy and those who did not. Complications included cataract (27%), retinopathy (25%), vitreous hemorrhage (19%), and orbital deformities (11%). In Group B the local control rate was 71%. In Group C, 10 (27%) of the 37 patients were alive at last contact, and 27 (73%) were either terminal or dead of disease. None of Group A or B patients had

Retrospective recall about children's symptoms is used to establish early developmental patterns in clinical practice and is also utilised in child psychopathology research. Some studies have indicated that the accuracy of retrospective recall is influenced by life events. Our hypothesis was that an intervention: speech and language therapy, would adversely affect the accuracy of parent recall of early concerns about their child's speech and language development. Mothers (n = 5,390) reported on their child's speech development (child male to female ratio = 50:50) when their children were aged 18 or 30 months, and also reported on these early concerns retrospectively, 10 years later, when their children were 13 years old. Overall reliability of retrospective recall was good, 86 % of respondents accurately recalling their earlier concerns. As hypothesised, however, the speech and language intervention was strongly associated with inaccurate retrospective recall about concerns in the early years (Relative Risk Ratio = 19.03; 95 % CI:14.78-24.48). Attendance at speech therapy was associated with increased recall of concerns that were not reported at the time. The study suggests caution is required when interpreting retrospective reports of abnormal child development as recall may be influenced by intervening events.

This study examined the incidence and risk factors for gastrointestinal (GI) bleeding after spontaneous intracerebral hemorrhage (ICH). The available medical records of patients with ICH admitted from June 2008 to December 2009 for any episode of GI bleeding, possible precipitating factors and administration of ulcer prophylaxis were reviewed. The prevalence of GI bleeding was 26.7%, including 3 cases of severe GI bleeding (0.35%). Patients with GI bleeding had significantly longer hospital stay and higher in-hospital mortality compared with patients without GI bleeding. Multivariate logistic regression analyses showed that age, Glasgow Coma Scale scores, sepsis and ICH volume were independent predictors of GI bleeding. About 63.4% of patients with ICH received stress ulcer prophylaxis. GI bleeding occurred frequently after ICH, but severe events were rare. Age, Glasgow Coma Scale score, sepsis and ICH volume were independent predictors of GI bleeding occurring after ICH.

Francisco José Tortosa Vallecillos

Full Text Available SUMMARY Objective: As a result of the use of neuroimaging techniques, silent pituitary lesions are diagnosed more and more frequently; however, there are few published post-mortem studies about this gland. Incidence data of pituitary lesions are rare and in Portugal they are outdated or even non-existent. The aim of this study is to determine the prevalence of normal patterns and incidental post-mortem pituitary pathology at Centro Hospitalar Lisboa Norte, analyzing the associations with clinical data and assessing the clinical relevance of the findings. Method: We reviewed retrospectively and histologically 167 pituitaries of a consecutive series of autopsies from the Department of Pathology of this centre. They were done between 2012 and 2014, and in all cases medical records were reviewed. The morphological patterns observed, were classified into three major groups: 1 Normal histological patterns and variants; 2 Infectious-inflammatory pathology, metabolic and vascular disorders; 3 Incidental primary proliferation and secondary to systemic diseases. Results: The subjects included in this study were of all age groups (from 1 day to 91 years old, 71 were female and 96 male. Fifty-seven of these glands didn’t show any alteration; 51 showed colloid cysts arising from Rathke cleft; 44 presented hyperplasia in adenohypophysis and we identified 20 adenomas in 19 glands (immunohistochemically, eight PRL-producing and five ACTH-producing tumors, ten of which associated with obesity, 11 to hypertension and six to diabetes mellitus. There were two cases with metastasis. Conclusion: Subclinical pathology in our country is similar to that seen in other parts of the world, but at older ages.

The increasing risk of a mass casualty scenario following a large scale radiological accident or attack necessitates the development of appropriate dosimetric tools for emergency response. Luminescence dosimetry has been reliably applied for dose reconstruction in contaminated settlements for several decades and recent research into new materials carried close to the human body opens the possibility of estimating individual doses for accident and emergency dosimetry using the same technique. This paper reviews the luminescence research into materials useful for accident dosimetry and applications in retrospective dosimetry. The properties of the materials are critically discussed with regard to the requirements for population triage. It is concluded that electronic components found within portable electronic devices, such as e.g. mobile phones, are at present the most promising material to function as a fortuitous dosimeter in an emergency response.

Purpose: We retrospectively evaluate the dosimetric impact of a 3.5% range uncertainty on CTV coverage and normal organ toxicity for a cohort of brain patients. Methods: Twenty treatment plans involving 20 brain cancer patients treated with Mevions S250 were reviewed. Forty uncertain plans were made by changing the ranges in original plans by ±3.5% while keeping all devices unchanged. Fidelity to the original plans was evaluated with gamma index. Changes in generalized equivalent uniform dose (gEUD) were reported for the following structures: CTV coverage, brainstem, optic chiasm, and optic nerves. Comparisons were made by plotting the relevant endpoints from the uncertain plans as a function of the same endpoints from the original clinical plan. Results: Gamma-index analysis resulted in a 50% pass rate of the uncertain plans using a 90% passing rate and 3%/3mm criterion. A 9.5% decrease in the slope of gEUD plot for the CTV was observed for the 3.5% downward range shift. However, the change in slope did not result in a gEUD change greater than 1.1% for the CTV. The slopes of the gEUD plots for normal structures increased by 3.1% 3.9% 2.4% and 0.2% for the chiasm, brainstem, left optic nerve and right optic nerve respectively. The maximum deviation from the gEUD of the clinical plan for normal structures was: 64% in the chiasm, 31% for the brainstem, and 19% for both optic nerves. Conclusion: A retrospective review shows moderate radiobiological impact of range uncertainty in passively scattered proton therapy with sporadic catastrophe. The linear regression analysis on the statistical data indicates a systematic deviation of gEUD from treatment planning in the light of range uncertainty.

RETROSPECTIVE DATA COLLECTION: CAN STUDENTS REMEMBER?

Directory of Open Access Journals (Sweden)

Paul Leeming

2015-01-01

Full Text Available Abstract: It is not always possible or practical to gather data over a long period of time, and researchers have used retrospective data from questionnaire and interview to gain insights into change over time. There has been little discussion within SLA as to the validity of this data, and it is seemingly accepted at face value. This paper examines both qualitative and quantitative retrospective accounts of changes in self-efficacy, by collecting quantitative questionnaire data over a one-year period, and then asking students to quantitatively recollect their feelings of self-efficacy over that time frame, followed by qualitative description. Results showed that students were able to accurately recollect quantitative data, although there was a noticeable degradation in accuracy with time. Interview data suggested that students were reluctant to admit lack of ability to recall events, and sometimes produced conflicting accounts of events.  This may in part be due to the dual role of teacher and researcher adopted in this study. The implications for researchers and also for teachers are considered.

2018-05-01

There has been a resurgence of syphilis diagnoses in Australia. We investigated whether our Treponema pallidum PCR test provides any additional diagnostic information over syphilis serology (chemiluminescence immunoassay [CMIA], Treponema pallidum particle agglutination [TPPA] assay, and the rapid plasma reagin [RPR] flocculation test). A retrospective audit of all T. pallidum PCR requests that came through our laboratory from January 2010 to June 2017 was conducted; data collected included age, gender, site of swab, and results from T. pallidum PCR, syphilis serology, and herpes simplex virus 1 (HSV-1) and HSV-2 PCRs. A total of 441 T. pallidum PCR tests were performed; on average, 3 T. pallidum PCRs per month were requested in 2011, and this rate increased to 17.2 requests per month in 2017. A total of 323 patients had both T. pallidum PCR and syphilis serology performed, with 67% of swabs taken from the genitals. T. pallidum PCR gave positive results for 61/323 (19%) patients; of these 61 patients, 59 (97%) also had positive syphilis serology results ( T. pallidum PCR sensitivity, 68%; specificity, 99%; positive predictive value, 97%; negative predictive value, 89%). Syphilis serology was positive for 91/323 patients (28%); of these 91 patients, 61 (66%) were also T. pallidum PCR positive (syphilis serology sensitivity, 97%; specificity, 88%; positive predictive value, 60%; negative predictive value, 99%). The Cohen's kappa value was 0.74, indicating substantial agreement between the two tests. Our results show that most patients with positive T. pallidum PCR results also had positive syphilis serology. Therefore, T. pallidum PCR adds little clinical value over serology for the diagnosis of syphilis in certain clinical settings. Copyright © 2018 American Society for Microbiology.

Full Text Available BACKGROUND: There have been few studies on children hospitalized with influenza published from mainland China. We performed a retrospective review of medical charts to describe the epidemiology, clinical features and direct medical cost of laboratory-proven influenza hospitalized children in Suzhou, China. METHODS: Retrospective study on children with documented influenza infection hospitalized at Suzhou Children Hospital during 2005-2009 was conducted using a structured chart review instrument. RESULTS: A total of 480 children were positive by immuno-fluorescent assay for influenza during 2005-2009. The hospitalizations for influenza occurred in 8-12 months of the year, most commonly in the winter with a second late summer peak (August-September. Influenza A accounted for 86.3%, and of these 286 (59.6% were male, and 87.2% were 60 months old had shorter hospital stay (OR = 0.45; children with oxygen treatment tended to have longer hospital stays than those without oxygen treatment (OR = 2.14. The mean cost of each influenza-related hospitalization was US$ 624 (US$ 1323 for children referred to ICU and US$ 617 for those cared for on the wards. High risk children had higher total cost than low-risk patients. CONCLUSION: Compared to other countries, in Suzhou, children hospitalized with influenza have longer hospital stay and higher percentage of pneumonia. The direct medical cost is high relative to family income. Effective strategies of influenza immunization of young children in China may be beneficial in addressing this disease burden.

Endoscopic stenting for hilar cholangiocarcinoma: efficacy of unilateral and bilateral placement of plastic and metal stents in a retrospective review of 480 patients

Science.gov (United States)

2012-01-01

Background Endoscopic biliary drainage of hilar cholangiocarcinoma is controversial with respect to the optimal types of stents and the extent of drainage. This study evaluated endoscopic palliation in patients with hilar cholangiocarcinoma using self-expandable metallic stents (SEMS) and plastic stents (PS).We also compared unilateral and bilateral stent placement according to the Bismuth classification. Methods Data on 480 patients receiving endoscopic biliary drainage for hilar cholangiocarcinoma between September 1995 and December 2010 were retrospectively reviewed to evaluate the following outcome parameters: technical success (TS), functional success (FS), early and late complications, stent patency and survival. Patients were followed from stent insertion until death or stent occlusion. Patients were divided into 3 groups according to the Bismuth classification (Group 1, type I; Group 2, type II; Group 3, type > III). Results The initial stent insertion was successful in 450 (93.8%) patients. TS was achieved in 204 (88.3%) patients treated with PS and in 246 (98.8%) patients palliated with SEMS (p stent patency in weeks (w) were as follows: 20 w in patients palliated with PS and 27 w in patients treated with SEMS (p stent patency. Conclusions SEMS insertion for the palliation of hilar cholangiocarcinoma offers higher technical and clinical success rates in the ITT analysis as well as lower complication rates and a superior cumulative stent patency when compared with PS placement in all Bismuth classifications. The cumulative patency of bilateral SEMS or PS stents was significantly higher than that of unilateral SEMS or PS stents, with lower occlusion rates in Bismuth II patients. PMID:22873816

PurposeThin-strut, flexible DES are suitable for intracranial stenting and may improve long-term vessel patency. The purpose of this study was to report our experience with two new-generation DES for the treatment of intracranial atherosclerotic disease.Patients and MethodsWe retrospectively reviewed all patients treated with Taxus Element™ or Resolute Integrity™ stent for an intracranial atherosclerotic stenosis between March 2011 and August 2013. Technical success was defined as the ability to deploy the device at the desired location and reduce the degree of stenosis below 50 %. All procedure-related strokes were recorded. Control angiography was scheduled after 6 weeks, 3, 6, and 12 months and yearly thereafter. A luminal narrowing ≥50 % was regarded as a restenosis. Stroke recurrence in the territory of the treated artery was reported.ResultsIn the defined period we treated 101 patients harboring 117 intracranial stenoses. The procedure was successful in 100 (85.5 %) lesions. Procedure-related strokes occurred in 10 (9.9 %) patients with a permanent morbidity in 3 (3.0 %). Follow-up angiography was available for 83 of 100 (83.0 %) successfully treated lesions with an average of 355 days (IQR 153–482 days). Three (3.6 %) asymptomatic restenoses were detected. All occurred after treatment with Resolute Integrity™, none after Taxus Element™ (p = 0.059). New strokes in the territory of the treated artery were encountered in 2 (2.6 %) occasions.ConclusionThin-strut DES improve long-term patency and reduce the risk of subsequent stroke. Differences between devices may exist. Feasibility is comparable to bare-metal balloon-mounted stents and procedure-related strokes occurred within the expected range.

Full Text Available Abstract Background Median sternotomy infection and bony nonunion are two commonly described complications which occur in 0.4 - 5.1% of cardiac procedures. Although relatively infrequent, these complications can lead to significant morbidity and mortality. The aim of this retrospective study is to evaluate the initial experience of a transverse plate fixation system following wound complications associated with sternal dehiscence with or without infection following cardiac surgery. Methods A retrospective chart review of 40 consecutive patients who required sternal wound reconstruction post sternotomy was performed. Soft tissue debridement with removal of all compromised tissue was performed. Sternal debridement was carried using ronguers to healthy bleeding bone. All patients underwent sternal fixation using three rib plates combined with a single manubrial plate (Titanium Sternal Fixation System®, Synthes. Incisions were closed in a layered fashion with the pectoral muscles being advanced to the midline. Data were expressed as mean ± SD, Median (range or number (%. Statistical analyses were made by using Excel 2003 for Windows (Microsoft, Redmond, WA, USA. Results There were 40 consecutive patients, 31 males and 9 females. Twenty two patients (55% were diagnosed with sternal dehiscence alone and 18 patients (45% with associated wound discharge. Thirty eight patients went on to heal their wounds. Two patients developed recurrent wound infection and required VAC therapy. Both were immunocompromised. Median post-op ICU stay was one day with the median hospital stay of 18 days after plating. Conclusion Sternal plating appears to be an effective option for the treatment of sternal wound dehiscence associated with sternal instability. Long-term follow-up and further larger studies are needed to address the indications, benefits and complications of sternal plating.

Late-onset vitiligo, defined as being aged 50 years and above at the point of clinical onset, remains poorly characterized till now. This study aims to describe the clinical characteristics and treatment response of patients with late-onset vitiligo. We retrospectively reviewed the case records of all patients diagnosed with late-onset vitiligo, from January 1, 2010 to December 31, 2014. Information obtained included patient demographics, characteristics of vitiligo and treatment responses. Of the 3128 patients diagnosed with vitiligo over the 5-year period, 461 (14.7%) had late-onset disease. The study had more females (n = 260, 56.4%) than males, with an average onset age of 59.4 ± 7.4 years. Majority of patients were Chinese (n = 308, 66.8%) and 45 (9.8%) patients had an associated autoimmune disease. Focal vitiligo, defined as the localized presence of depigmented patches, was most common (n = 209, 45.3%). Treatment response was evaluated in 359 patients, of which 216 received monotherapy (topical creams: n = 210, 97.2%; phototherapy: n = 6, 2.8%) and 143 received both modalities. Fifty six (15.6%) patients received oral steroids. Patients who were treated with both topical creams and phototherapy yielded better clinical responses compared to those on monotherapy (P 50% return of pigmentation compared to baseline (vs. n = 66, 30.6% in the monotherapy group). The choice of phototherapy (targeted, narrowband ultraviolet B or psoralen + ultraviolet A) did not significantly affect clinical response (P = 0.774). This study is limited by its retrospective nature, the nonstandardized documentation resulting in the inability to determine disease progression and associated metabolic comorbidities and also by the gradual loss to follow-up of patients. Late-onset vitiligo is not uncommon and tends to be of the focal vitiligo subtype. Nonsegmented vitiligo is more prevalent than segmental vitiligo. Combination therapy with topical medications and phototherapy is superior

Nitrate/nitrite poisoning was the most commonly diagnosed plant-associated intoxication, followed by gossypol and oleander. This study details the diagnostic challenges and treatment options for the most commonly diagnosed intoxications. To ensure proper treatment and prevention of new cases, accurate diagnosis is necessary, and therefore this review provides an essential tool for the food animal practitioner. Available toxicological analyses are offered at select laboratories, which can be time consuming and expensive, yet the potential for residues in consumed animal products and implications for human health necessitate testing and consultation. Any potential exposure to a toxicant in cattle should be reviewed to determine whether a residue hazard exists. Therapy focuses on immediate removal of the toxicant from the environment and from the gastrointestinal tract. With few antidotes available, most are cost prohibitive to treat numerous affected cattle. In addition, most antidotes will require extra-label drug use and establishment of meat and milk withdrawal times.Keywords: toxins, toxicology, poisonous plants, bovine

Full Text Available Abstract Background Previous studies have reported conflicting results for the comparative doses of recombinant follicle stimulating hormone (rFSH and highly purified human menopausal gonadotrophin (hMG-HP required per cycle of in vitro fertilisation (IVF; the aim of this study was to determine the average total usage of rFSH versus hMG-HP in a 'real-world' setting using routine clinical practice. Methods This retrospective chart review of databases from four European countries investigated gonadotrophin usage, oocyte and embryo yield, and pregnancy outcomes in IVF cycles (± intra-cytoplasmic sperm injection using rFSH or hMG-HP alone. Included patients met the National Institute for Health and Clinical Excellence (NICE guideline criteria for IVF and received either rFSH or hMG-HP. Statistical tests were conducted at 5% significance using Chi-square or t-tests. Results Of 30,630 IVF cycles included in this review, 74% used rFSH and 26% used hMG-HP. A significantly lower drug usage per cycle for rFSH than hMG-HP (2072.53 +/- 76.73 IU vs. 2540.14 +/- 883.08 IU, 22.6% higher for hMG-HP; p Conclusions Based on these results, IVF treatment cycles with rFSH yield statistically more oocytes (and more mature oocytes, using significantly less IU per cycle, versus hMG-HP. The incidence of all OHSS and hospitalisations due to OHSS was significantly higher in the rFSH cycles compared to the hMG-HP cycles. However, the absolute incidence of hospitalisations due to OHSS was similar to that reported previously. These results suggest that the perceived required dosage with rFSH is currently over-estimated, and the higher unit cost of rFSH may be offset by a lower required dosage compared with hMG-HP.

The purpose of this retrospective study was to describe the magnetic resonance imaging (MRI) features of Poly Implant Prothèse (PIP) hydrogel implants in a group of 64 patients and to assess the incidence of rupture, compared to other clinical trials. In this double-center study, we retrospectively reviewed the data sets of 64 consecutive patients (mean age, 43±9 years, age range, 27-65 years), who underwent breast MRI examinations, between January 2008 and October 2013, with suspected implant rupture on the basis of clinical assessment or after conventional imaging examination (either mammography or ultrasound). All patients had undergone breast operation with bilateral textured cohesive gel PIP implant insertion for aesthetic reasons. The mean time after operation was 8 years (range, 6-14 years). No patients reported history of direct trauma to their implants. At the time of clinical examination, 41 patients were asymptomatic, 16 complained of breast tenderness and 7 had clinical evidence of rupture. Normal findings were observed in 15 patients. In 26 patients there were signs of mild collapse, with associated not significant peri-capsular fluid collections and no evidence of implant rupture; in 23 patients there was suggestion of implant rupture, according to breast MRI leading to an indication for surgery. In particular, 14 patients showed intra-capsular rupture, with associated evidence of the linguine sign in all cases; the keyhole sign and the droplet signs were observed in 6 cases. In 9 patients there was evidence of extra-capsular rupture, with presence of axillary collections (siliconomas) in 7 cases and peri-prosthetic and mediastinal cavity siliconomas, in 5 cases. The results of this double center retrospective study, confirm the higher incidence (36%) of prosthesis rupture observed with the PIP implants, compared to other breast implants.

The purpose of this study was to determine clinical and ultrasonographic characteristics of male breast tumors. The medical records of male patients with breast lesions were retrieved from an electronic medical record database and a pathology database and retrospectively reviewed. A total of 112 men (125 breast masses) with preoperative breast ultrasonography (US) were included (median age, 59.50 years; age range, 15-96 years). Data extracted included patient age, if the lesions were bilateral, palpable, and tender, and the presence of nipple discharge. Breast lesion features on static US images were reviewed by three experienced radiologists without knowledge of physical examination or pathology results, original breast US image interpretations, or surgical outcomes. The US features were documented according to the BI-RADS (Breast Imaging-Reporting and Data System) US lexicons. A forth radiologist compiled the data for analysis. Of the 125 breast masses, palpable tender lumps and bilateral synchronous masses were more likely to be benign than malignant (both, 100% vs 0%, P nipples were common in malignant lesions (P nipple, irregular shape, the presence of an echogenic halo, predominantly internal vascularity, and rich color flow signal on color Doppler ultrasound were significantly related to malignancy (all, P < 0.05). An echogenic halo and the presence of rich color flow signal were independent predictors of malignancy. Specific clinical and US characteristics of male breast tumors may help guide treatment, and determine if surgery or conservative treatment is preferable.

Objectives: Although several detailed studies concerning the patient profile and clinical features of oral lichen planus have been undertaken all over the world in different populations, a similar study has not yet been conducted in a Turkish population. The purpose of this retrospective study was to describe the demographic and clinical characteristics of a group of patients with oral lichen planus in Turkey. Study Design: Charts of 370 patients, from the archive of Oral Diagnosis and Radiology Department of Marmara University Faculty of Dentistry (Istanbul, Turkey), with histologically confirmed clinical diagnosis of oral lichen planus in the period 1990-2010 were retrospectively reviewed. Results: Of the 370 patients, 260 (70.3%) were women and 110 (29.7%) were men. The mean age was 49.84±13.41 years (range of 16-83). The lesions were asymptomatic in 63 patients (17%). Nearly half of the patients (47.6%) had multiple sites of involvement. Predominantly red forms were the most frequent, affecting 60.5% of patients. Approximately 17% of the patients had symptoms of possible extraoral involvement. No evidence suggesting a connection between oral lichen planus and tobacco or alcohol use was found. Only one out of the 370 cases had histologically proven malignant transformation. Conclusions: The patient profile and clinical features of oral lichen planus in Turkey were generally similar to those described in other populations. The preponderance of the red forms and also the fact that majority of patients referred themselves to our clinic highlighted the lack of awareness among Turkish health care providers about lichen planus. Key words:Oral lichen planus, clinical features, patient profile. PMID:23524413

Retrospective Attention Interacts with Stimulus Strength to Shape Working Memory Performance.

Wildegger, Theresa; Humphreys, Glyn; Nobre, Anna C

2016-01-01

Orienting attention retrospectively to selective contents in working memory (WM) influences performance. A separate line of research has shown that stimulus strength shapes perceptual representations. There is little research on how stimulus strength during encoding shapes WM performance, and how effects of retrospective orienting might vary with changes in stimulus strength. We explore these questions in three experiments using a continuous-recall WM task. In Experiment 1 we show that benefits of cueing spatial attention retrospectively during WM maintenance (retrocueing) varies according to stimulus contrast during encoding. Retrocueing effects emerge for supraliminal but not sub-threshold stimuli. However, once stimuli are supraliminal, performance is no longer influenced by stimulus contrast. In Experiments 2 and 3 we used a mixture-model approach to examine how different sources of error in WM are affected by contrast and retrocueing. For high-contrast stimuli (Experiment 2), retrocues increased the precision of successfully remembered items. For low-contrast stimuli (Experiment 3), retrocues decreased the probability of mistaking a target with distracters. These results suggest that the processes by which retrospective attentional orienting shape WM performance are dependent on the quality of WM representations, which in turn depends on stimulus strength during encoding.

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

2018-04-01

The incidence and prevalence of skin tears in long-term care (LTC) facilities has not been well established. To ascertain the point prevalence of reported skin tears, a retrospective review of incident reports was performed in 6 LTC facilities in western Pennsylvania from November 1, 2016 through December 31, 2016. Report data, including resident age; gender; mobility limitations; skin tear location, number, and cause (if known); occurrence time (7 am to 3 pm, 3 pm to 11 pm, or 11 pm to 7 am nursing shift); and history of previous skin tears, were abstracted. All data were entered into a statistical analysis program and analyzed using descriptive statistics. Period prevalence was used to determine prevalence rate; an independent t test was used to compare the presence of skin tears between genders. Differences between location and cause of skin tears were evaluated using a multinomial test of related proportions. A test of proportions was used to evaluate skin tear occurrence time (nursing shift) differences. The overall point prevalence rate was 9% (N = 1253 residents) ranging from 6 to 28 skin tears per facility. The average age of residents with a skin tear (n = 119) was 83.5 years. The majority (111, 93%) had mobility limitations. Falls accounted for 38 skin tears (31.9%), followed by propelling in a wheelchair (18, 15.1%; X2 =7.14; P = .008). Forearm skin tears (37, 31.1%) occurred significantly more frequently than lower leg skin tears (19, 16%; P = .016). Significantly more skin tears occurred during the 7 am to 3 pm shift (47, 39.5%) and 3 pm to 11 pm shift (49, 41.2%) than during the 11 pm to 7 am shift (23, 19.3%; X2 = 5.78; P skin tears are a significant problem among elderly residents in LTC, especially because the reported rate is likely lower than the actual rate. Research to further elucidate the incidence and prevalence of skin tears and associated risk factors is needed to help develop evidence-based risk assessment, classification systems

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.

To quantify and retrospectively correct for systematic differences in diffusion tensor imaging (DTI) measurements due to differences in coil combination mode. Multi-channel coils are now standard among MRI systems. There are several options for combining signal from multiple coils during image reconstruction, including sum-of-squares (SOS) and adaptive combine (AC). This contribution examines the bias between SOS- and AC-derived measures of tissue microstructure and a strategy for limiting that bias. Five healthy subjects were scanned under an institutional review board-approved protocol. Each set of raw image data was reconstructed twice-once with SOS and once with AC. The diffusion tensor was calculated from SOS- and AC-derived data by two algorithms-standard log-linear least squares and an approach that accounts for the impact of coil combination on signal statistics. Systematic differences between SOS and AC in terms of tissue microstructure (axial diffusivity, radial diffusivity, mean diffusivity and fractional anisotropy) were evaluated on a voxel-by-voxel basis. SOS-based tissue microstructure values are systematically lower than AC-based measures throughout the brain in each subject when using the standard tensor calculation method. The difference between SOS and AC can be virtually eliminated by taking into account the signal statistics associated with coil combination. The impact of coil combination mode on diffusion tensor-based measures of tissue microstructure is statistically significant but can be corrected retrospectively. The ability to do so is expected to facilitate pooling of data among imaging protocols. Copyright © 2016 Elsevier Inc. All rights reserved.

2016-01-01

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.

Benign Paroxysmal Positional Vertigo (BPPV) has been linked to comorbidities like diabetes and hypertension. However, the relationship between type 2 diabetes (DM) and BPPV is unclear. The purpose of this retrospective study was to examine the relationship between DM and BPPV in the presence of known contributors like age, gender and hypertension. A retrospective review of the records of 3933 individuals was categorized by the specific vestibular diagnosis and for the presence of type 2 DM and hypertension. As the prevalence of BPPV was higher in people with type 2 DM compared to those without DM, multivariable logistic regressions were used to identify variables predictive of BPPV. The relationship between type 2 DM, hypertension and BPPV was analyzed using mediation analysis. BPPV was seen in 46% of individuals with type 2 DM, compared to 37% of individuals without DM (pdiabetes affects the vestibular system. Individuals with complaints of dizziness, with comorbidities including hypertension and diabetes, may benefit from a screening for BPPV.

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.

2014-09-01

To evaluate at what age parous and nonparous women were diagnosed with breast cancer. Factors taken into account for parous women were whether they had breastfed their children, and if so, the length of the lactation period. Other factors considered for both groups were obesity, family histories of cancer, smoking habits and alcohol consumption. Breast cancer is the most common form of cancer in younger women in Western countries. Its growing incidence as well as the increasingly early age of diagnosis led us to carefully analyse its possible causes and the preventive measures to be taken. This is a particularly important goal in epidemiological research. A retrospective study of the clinical histories of patients diagnosed with breast cancer at the San Cecilio University Hospital in Granada (Spain). In this study, we analysed 504 medical records of female patients, 19-91 years of age, who had been diagnosed and treated for breast cancer from 2004-2009 at the San Cecilio University Hospital in Granada (Spain). Relevant data (age of diagnosis, period of lactation, family history of cancer, obesity, alcohol consumption and smoking habits) were collected from the clinical histories of each patient and analysed. A conditional inference tree was used to relate the age of diagnosis to smoking habits and the length of the lactation period. The conditional inference tree identified significant differences between the age of the patients at breast cancer diagnosis, smoking habits (p cancer. Our study concluded that breastfeeding for over six months not only provides children with numerous health benefits, but also protects mothers from breast cancer when the mothers are nonsmokers. Nurses play a crucial role in encouraging new mothers to breastfeed their children, and this helps to prevent breast cancer. © 2013 John Wiley & Sons Ltd.

Review of Dengue hemorrhagic fever fatal cases seen among adults: a retrospective study.

Directory of Open Access Journals (Sweden)

Sing-Sin Sam

Full Text Available BACKGROUND: Dengue is a mosquito-borne viral disease endemic in many countries in the tropics and sub-tropics. The disease affects mainly children, but in recent years it is becoming more of an adult disease. Malaysia experienced a large dengue outbreak in 2006 to 2007, involving mostly adults, with a high number of deaths. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a retrospective study to examine dengue death cases in our hospital from June 2006 to October 2007 with a view to determine if there have been changes in the presentation of severe to fatal dengue. Nine of ten fatal cases involved adult females with a median age of 32 years. All had secondary dengue infection. The mean duration of illness prior to hospitalization was 4.7 days and deaths occurred at an average of 2.4 days post-admission. Gastrointestinal pain, vomiting, diarrhea, intravascular leakages and bleeding occurred in the majority of cases. DSS complicated with severe bleeding, multi-organ failure and coagulopathy were the primary causes of deaths. Seven patients presented with thrombocytopenia and hypoalbuminemia, five of which had hemoconcentration and increased ALT and AST indicative of liver damage. Co-morbidities particularly diabetes mellitus was common in our cohort. Prominent unusual presentations included acute renal failure, acute respiratory distress syndrome, myocarditis with pericarditis, and hemorrhages over the brain and heart. CONCLUSIONS: In our cohort, dengue fatalities are seen primarily in adult females with secondary dengue infection. The majority of the patients presented with common clinical and laboratory warning signs of severe dengue. Underlying co-morbidities may contribute to the rapid clinical deterioration in severe dengue. The uncommon presentations of dengue are likely a reflection of the changing demographics where adults are now more likely to contract dengue in dengue endemic regions.

Full Text Available Organ donation after brain death (BD is a major source for obtaining transplantable organs for patients with end-stage organ disease (ESOD. This retrospective, descriptive study was carried out on all potential BD patients admitted in different intensive care units (ICUs of the Hamad medical Corporation (HMC, Doha, Qatar during a period from January 2011 to April 2012. Our aim was to evaluate various demographic criteria and challenges of organ donation among potential BD organ donors and plan a strategy to improve the rate of organ donation in Qatar. Various aspects of BD patients in the ICUs and their possible effects on organ donation were studied. The time intervals analyzed to determine the possible causes of delay of organ retrieval were: time of diagnosing fixed dilated pupils in the ICU, to performing the first BD test, then to the second BD test, to family approach, to organ retrieval and/or circulatory death (CD without organ retrieval. There were a total of 116 potential BD organ donors of whom 96 (82.75% were males and 20 (17.25% were females. Brain hemorrhage and head injury contributed to 37 (31.9% and 32 (27.6% BD cases, respectively. Time interval between diagnosing fixed dilated pupil and performing the first test of BD was delayed >24 h in 79% of the cases and between the first and second BD tests was >6 h in 70.8% of the cases. This delay is not compatible with the Hamad Medical Corporation (HMC policy for BD diagnosis and resulted in a low number of organs retrieved. BD organ donation, a potential source for organs to save patients with ESOD has several pitfalls and every effort should be made to increase the awareness of the public as well as medical personnel to optimize donation efficacy.

To study the demographic characteristics of ocular trauma in Central Sarawak and identify the determinant factors of poor visual outcome. A retrospective study of ocular trauma cases presenting at the referral hospital in 2013. Patients were identified and recruited from hospital records. Those presenting for follow-up review were excluded. Case records were retrieved and reviewed after recruitment. We studied 168 patients with 179 ocular injuries, of which 44% were work related. Compared with non-work-related cases, work-related cases were more likely to be male [odds ratio (OR), 19.7; 95% confidence interval (CI), 2.6-150.9] and foreign (OR, 18.0; 95% CI, 2.3-142.0). Open globe injuries constituted a higher percentage of impaired visual acuity (VA) during the first visit: 84.6% compared with 18.1% for closed globe injuries (OR, 25.0; 95% CI, 5.3-118.4; P Sarawak were predominantly work related, occurring at industrial premises, and involving males and foreigners. Both open globe injuries and a delay in seeking treatment resulted in significantly poorer visual outcomes.

After taking either 200 mg caffeine or a placebo, participants touched a 17-sided polygon for 15 s. Then they verbally estimated the number of angles and the duration. Participants in the prospective group were told in advance they would be making a duration estimate, whereas those in the retrospective group were not told. Caffeine reduced duration estimates in the prospective condition but not in the retrospective condition. The effect of caffeine on very long duration comparisons (the past year compared with a year at one-half and one-quarter of one's age) was also evaluated, but none was found. The findings do not support the hypothesis that caffeine affects duration experience by increasing the internal clock rate as a result of its dopamine D(2) agonist properties. The hypothesis that caffeine produces its effect by enhancing memory was considered and rejected. The most parsimonious explanation is that caffeine increased arousal level, which led to a narrowing of the focus of attention to the most salient task. Copyright 2003 John Wiley & Sons, Ltd.

Full Text Available Abstract Background Experience suggests that patients with alcohol and other drug use disorders (AOD are commonly cared for in our intensive care units (ICU's and require more sedation. We sought to determine the impact of AOD on sedation requirement and mechanical ventilation (MV duration. Methods Retrospective review of randomly selected records of adult patients undergoing MV in the medical ICU. Diagnoses of AOD were identified using strict criteria in Diagnostic and Statistical Manual of Mental Disorders, and through review of medical records and toxicology results. Results Of the 70 MV patients reviewed, 27 had AOD (39%. Implicated substances were alcohol in 22 patients, cocaine in 5, heroin in 2, opioids in 2, marijuana in 2. There was no difference between AOD and non-AOD patients in age, race, or reason for MV, but patients with AOD were more likely to be male (21 versus 15, p Conclusion The prevalence of AOD among medical ICU patients undergoing MV is high. Patients with AOD receive higher doses of sedation than their non-AOD counterparts to achieve similar RASS scores but do not undergo longer duration of MV.

Patients with diabetic foot ulcers (DFU) have an increased risk of lower extremity amputation. A retrospective chart review of patients with DFUs attending the Foot Treatment and Assessment chiropodist-led outpatient clinic at an inner-city academic hospital was conducted to determine wound healing outcomes and characteristics contributing to outcomes. We reviewed the complete clinical history of 279 patients with 332 DFUs spanning over a five-year period. The mean age of patients was 61.5±12.5 years and most patients (83.5%) had one DFU. The majority of wounds (82.5%) were in the forefoot. Overall, 267/332 (80.5%) wounds healed. A greater proportion of wounds healed in the forefoot (82.5%) and midfoot (87.1%) than hindfoot (51.9%; phealing. Our findings are the first to demonstrate the benefits of chiropodists leading an acute care outpatient clinic in the management of DFUs in Canada and delivers wound healing outcomes equivalent to or exceeding those previously published.

Computed Tomography Cholangiography (CTC) is a fast and widely available alternative technique to visualise hepatobiliary disease in patients with an inconclusive ultrasound when MRI cannot be performed. The method has previously been relatively unknown and sparsely used, due to concerns about adverse reactions and about image quality in patients with impaired hepatic function and thus reduced contrast excretion. In this retrospective study, the feasibility and the frequency of adverse reactions of CTC when using a drip infusion scheme based on bilirubin levels were evaluated. The medical records of patients who had undergone upper abdominal spiral CT with subsequent three-dimensional rendering of the biliary tract by means of CTC during seven years were retrospectively reviewed regarding serum bilirubin concentration, adverse reaction and presence of visible contrast media in the bile ducts at CT examination. In total, 153 consecutive examinations in 142 patients were reviewed. Contrast media was observed in the bile ducts at 144 examinations. In 110 examinations, the infusion time had been recorded in the medical records. Among these, 42 examinations had an elevated bilirubin value (>19 umol/L). There were nine patients without contrast excretion; 3 of which had a normal bilirubin value and 6 had an elevated value (25–133 umol/L). Two of the 153 examinations were inconclusive. One subject (0.7%) experienced a minor adverse reaction – a pricking sensation in the face. No other adverse effects were noted. We conclude that drip infusion CTC with an infusion rate of the biliary contrast agent iotroxate governed by the serum bilirubin value is a feasible and safe alternative to MRC in patients with and without impaired biliary excretion. In this retrospective study the feasibility and the frequency of adverse reactions when using a drip infusion scheme based on bilirubin levels has been evaluated

2018-01-01

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 Abstract Background Estimates of baseline incidence of childhood intussusception could help safety monitoring after the introduction of rotavirus vaccines. We studied the incidence of intussusception in Uzbekistan, a GAVI-fund eligible state in Central Asia. Methods We retrospectively reviewed intussusception cases in children Results Over a 5-year study period, 67 confirmed cases were identified, of which 67% were boys. The median age was 12 months, and no seasonal trend in the distribution of cases was observed. The diagnostic methods used included abdominal radiography (87% and ultrasonography (57%. Intussusception reduction by air enema was successful in 33 (49% patients and 34 (50% cases underwent surgery. A total of 4 deaths occurred, including 3 deaths in infants aged 0-6 months. The median length of hospital stay was 7.3 (range 0-37 days. The incidence of intussusception is estimated at 23 (95% CI 13.6-32.4 cases per 100,000 child-years, corresponding to approximately 237 cases annually. Conclusions This is the first study to estimate the incidence of childhood intussusception prior to the introduction of the rotavirus vaccination in Uzbekistan. A prospective surveillance system using a standardized case definition is needed in order to better examine the occurrence of intussusception in developing countries.

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.

How often do surgeons intervene on shoulder labral lesions detected at MR examination? A retrospective review of MR examinations correlated with arthroscopy

Science.gov (United States)

2014-01-01

Objective: We report the prevalence of surgical intervention on shoulder labral lesions detected at MR examinations and how surgeons describe labral tears seen at MR examinations in their arthroscopy reports. Methods: A retrospective review of 100 consecutive patients aged 50 years or younger who had shoulder labral tears on MR and went on to have surgery performed. It was determined whether surgical intervention was performed on the MR lesions. Results: Of these 100 patients, 72 had superior labral anterior to posterior (SLAP) tears, 38 had posterior labral tears and 28 had anterior labral tears on MR examination. All 100 patients went on to arthroscopy. All lesions described on MRI were described on arthroscopy. Of the 72 SLAP tears, 64 were described as fraying on arthroscopy with 51 debrided. The remaining eight SLAP tears were tacked surgically. Of the 38 posterior labral tears, 36 were described as fraying on arthroscopy with 29 debrided and 2 had surgical tacking performed. Of the 28 anterior labral tears described on MR examination, 26 had surgical tacking performed and 2 were debrided. There were four SLAP tears, two anterior labral tears and three posterior labral tears seen on arthroscopy but not seen on MR examination. Conclusion: In this series, a high percentage of SLAP tears and posterior labral tears described on MR examination did not have surgical tacking. Most anterior labral tears had surgical tacking. Based on the above, our surgeons request we describe superior and posterior labral lesions as fraying and/or tearing, unless we can see a displaced tear. Most anterior labral lesions are treated with surgical tacking. Advances in knowledge: MRI allows for sensitive detection of labral tears. The tears often are not clinically significant.

2018-06-01

Purpose The purpose of this study was to compare medications and potential risk factors between patients who experienced a fall during hospitalization compared to those who did not fall while admitted to the Blood and Marrow Transplant inpatient setting at The James Cancer Hospital. Secondary objectives included evaluation of transplant-related disease states and medications in the post-transplant setting that may lead to an increased risk of falls, post-fall variables, and number of tests ordered after a fall. Methods This retrospective, case-control study matched patients in a 2:1 ratio of nonfallers to fallers. Data from The Ohio State University Wexner Medical Center (OSUWMC) reported fall events and patient electronic medical records were utilized. A total of 168 adult Blood and Marrow Transplant inpatients with a hematological malignancy diagnosis were evaluated from 1 January 2010 to 30 September 2012. Results Univariable and multivariable conditional logistic regression models were used to assess the relationship between potential predictor variables of interest and falls. Variables that were found to be significant predictors of falls from the univariable models include age group, incontinence, benzodiazepines, corticosteroids, anticonvulsants and antidepressants, and number of days status-post transplant. When considered for a multivariable model age group, corticosteroids, and a cancer diagnosis of leukemia were significant in the final model. Conclusion Recent medication utilization such as benzodiazepines, anticonvulsants, corticosteroids, and antidepressants placed patients at a higher risk of experiencing a fall. Other significant factors identified from a multivariable analysis found were patients older than age 65, patients with recent corticosteroid administration and a cancer diagnosis of leukemia.

Retrospective Attention Interacts with Stimulus Strength to Shape Working Memory Performance.

Directory of Open Access Journals (Sweden)

Theresa Wildegger

Full Text Available Orienting attention retrospectively to selective contents in working memory (WM influences performance. A separate line of research has shown that stimulus strength shapes perceptual representations. There is little research on how stimulus strength during encoding shapes WM performance, and how effects of retrospective orienting might vary with changes in stimulus strength. We explore these questions in three experiments using a continuous-recall WM task. In Experiment 1 we show that benefits of cueing spatial attention retrospectively during WM maintenance (retrocueing varies according to stimulus contrast during encoding. Retrocueing effects emerge for supraliminal but not sub-threshold stimuli. However, once stimuli are supraliminal, performance is no longer influenced by stimulus contrast. In Experiments 2 and 3 we used a mixture-model approach to examine how different sources of error in WM are affected by contrast and retrocueing. For high-contrast stimuli (Experiment 2, retrocues increased the precision of successfully remembered items. For low-contrast stimuli (Experiment 3, retrocues decreased the probability of mistaking a target with distracters. These results suggest that the processes by which retrospective attentional orienting shape WM performance are dependent on the quality of WM representations, which in turn depends on stimulus strength during encoding.

Ulichney, Robert A.

1999-12-01

Digital halftoning remains an active area of research with a plethora of new and enhanced methods. While several fine overviews exist, this purpose of this paper is to review retrospectively the basic classes of techniques. Halftoning algorithms are presented by the nature of the appearance of resulting patterns, including white noise, recursive tessellation, the classical screen, and blue noise. The metric of radially averaged power spectra is reviewed, and special attention is paid to frequency domain characteristics. The paper concludes with a look at the components that comprise a complete image rendering system. In particular when the number of output levels is not restricted to be a power of 2. A very efficient means of multilevel dithering is presented based on scaling order- dither arrays. The case of real-time video rendering is considered where the YUV-to-RGB conversion is incorporated in the dithering system. Example illustrations are included for each of the techniques described.

The test reports for the RF-induced heating of metallic devices of hundreds of medical implants have been provided to the U.S. Food and Drug Administration as a part of premarket submissions. The main purpose of this study is to perform a retrospective analysis of the RF-induced heating data provided in the reports to analyze the trends and correlate them with implant geometric characteristics. The ASTM-based RF heating test reports from 86 premarket U.S. Food and Drug Administration submissions were reviewed by three U.S. Food and Drug Administration reviewers. From each test report, the dimensions and RF-induced heating values for a given whole-body (WB) specific absorption rate (SAR) and local background (LB) SAR were extracted and analyzed. The data from 56 stents were analyzed as a subset to further understand heating trends and length dependence. For a given WB SAR, the LB/WB SAR ratio varied significantly across the test labs, from 2.3 to 11.3. There was an increasing trend on the temperature change per LB SAR with device length. The maximum heating for stents occurred at lengths of approximately 100 mm at 3 T, and beyond 150 mm at 1.5 T. Differences in the LB/WB SAR ratios across testing labs and various MRI scanners could lead to inconsistent WB SAR labeling. Magnetic resonance (MR) conditional labeling based on WB SAR should be derived from a conservative estimate of global LB/WB ratios. Published 2018.

Myotonic dystrophy type 1 (DM1), a neuromuscular disorder, is divided into four clinical phenotypes: congenital; childhood; adult-onset, and late-onset. Publications about the childhood phenotype, especially the long-term outcome, are scarce. The aims of this study were to assess and describe participation outcomes in adults with the childhood phenotype. A retrospective chart methodology. Data were extracted from health records for 63 adults with childhood DM1 (32 males, 31 females; mean age 34y, standard deviation [SD] 11y 6mo; range 18-54y) who had attended the Saguenay Neuromuscular Clinic, Canada. Thirty-four adults (54%) lived with their parents or in foster homes, and most patients needed services or help to live independently. A significant proportion (22%) were isolated in regard to friendship. Very few adults had children, although 33% lived with a spouse. The majority of patients (86%) relied on social security and only one person was currently working. Financial responsibilities were often an issue and 13 (21%) were under legal guardianship. This study showed that patients with the childhood phenotype present a guarded prognosis regarding long-term social participation. These participation restrictions could be related to behavioural, cognitive, and social stigma problems in childhood. This study illustrates the absolute necessity to pursue an interdisciplinary follow-up of these patients when they are reaching adulthood. © 2016 Mac Keith Press.

Nguyen, Trang D; Freilich, Marshall M; Macpherson, Bruce A

2016-06-01

To assess morbidity and mortality associated with oral and maxillofacial surgery procedures requiring general anesthesia among children with aspiration tendency requiring enteral feeding. A retrospective chart review was conducted of children surgically treated under general anesthesia by the oral and maxillofacial surgery service at the Hospital for Sick Children in Toronto, Canada. Medical and dental records over a 9-year period (January 1, 2000 to January 1, 2010) were reviewed. Data were collected on demographics, primary illness, coexisting medical conditions, procedures performed, medications administered, type of airway management used, duration of general anesthesia, American Society of Anesthesiologists' physical status classification and adverse events. During the period reviewed, 28 children underwent 35 oral and maxillofacial surgery procedures under general anesthesia. The mean patient age was 12 years (range 4-17 years). No deaths occurred. Of the 35 surgeries, 10 (29%) were associated with at least 1adverse event. Adverse events included 1incident of respiratory distress, 2incidents of fever, 5incidents of bleeding, 1incident of seizure and 4incidents of oxygen saturation below 90% for more than 30s. Children with a history of aspiration tendency that necessitates enteral feeding, who undergo oral and maxillofacial surgery under general anesthesia, are at increased risk of morbidity. Before initiating treatment, the surgeon and parents or guardians of such children should carefully consider these risks compared with the anticipated benefit of surgery.

Objectives: The aim of this study was to analyze the histopathologically diagnosed cases of oral lichen planus (OLP) in terms of age, gender, clinical variant, site, hyperpigmentation, systemic illness, grade of dysplasia, and associated malignant transformation. This study also intended to do a review of reported cases of OLP with malignant transformation. Materials and Methods: One hundred and forty-three cases of histopathologically diagnosed OLP between 2010 and 2016 were retrospectively reviewed. Demographic and clinicopathological data including malignant transformation were obtained. The data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS) software for Windows version 20.0 (IBM SPSS, SPSS Inc., Chicago, IL, USA). A review of published literature on OLP with malignant transformation was also done from 1988 to 2017 and tabulated. Results: OLP in this study showed a male predilection with most of the patients in the third decade. The buccal mucosa (bilateral presentation) was the most common site (79.72%), and reticular type was the most common clinical type (79.02%) followed by erosive type (20.98%). The majority (92.31%) of cases were diagnosed with OLP without dysplasia. The rest (7.69%) of dysplastic cases were predominantly seen in the buccal mucosa of 58 years and above, female patients manifesting mainly as erosive type. Two patients (1.4%) previously diagnosed clinically and histopathologically as OLP developed oral squamous cell carcinoma. Conclusion: The present investigation revealed the predominance of OLP among middle-aged male population and the prevalence of bilateral involvement of buccal mucosa. Two of our cases showed malignant transformation over an average period of 3.5 years. The outcome of this study emphasizes the role of clinical follow-up of patients with OLP. PMID:28584781

To correlate shoulder ultrasound and radiography with F-FDG PET-CT to establish FDG uptake and therefore range of metabolic activity, as defined by SUV analysis, in various symptomatic shoulder pathologies. Retrospective database query was performed for shoulder ultrasound and PET-CT scans between January 2012 and January 2017. Patients who had both studies within 1 year were included. Age- and sex-matched control patients with PET-CT scans only were also included. Retrospective image review determined shoulder pathology, and F-FDG SUVmax was measured using regions of interest placed at the glenohumeral joint, rotator cuff/bursa, and bicipital groove. Glenohumeral and acromioclavicular osteoarthrosis was assessed by radiography using the Kellgren-Lawrence classification system. Thirty-three patients had both imaging studies within 1 year. Ten patients (11 cases) were included, ranging in age from 56 to 90 years (mean, 67.9 years). Control subjects were selected among patients receiving PET-CT within 1 week of symptomatic patients. Glenohumeral osteoarthrosis was mild in 3 (27%), moderate in 2 (18%), and severe in 2 (18%). Six full-thickness rotator cuff tears (55%) were identified. SUVmax means were compared between the pathologic and control groups and were significantly higher in the former: glenohumeral joint (1.96 vs 1.32; P = 0.016), rotator cuff/bursa (2.80 vs 2.0; P = 0.005), and bicipital groove (2.19 vs 1.48; P = 0.007). The highest values were seen in full-thickness rotator cuff tear and severe biceps tenosynovitis. Increased metabolic activity about the shoulder is associated with a spectrum of rotator cuff, glenohumeral joint, and other soft tissue pathology that can be correlated with diagnostic ultrasound findings.

Computed tomography (CT) for evaluation of occult and suspect hip fractures has been proposed as a good second-line investigation. The diagnostic precision compared to magnetic resonance imaging (MRI) is unclear. To compare the diagnostic performance of CT and MRI in a retrospective study on patients with suspect and occult hip fractures. Forty-four elderly consecutive patients with low-energy trauma to the hip were identified where negative or suspect CT was followed by MRI. Primary reporting and review by two observers as well as the diagnostic performance of the two modalities were compared. Surgical treatment and clinical course were used as outcomes. Compared to the primary reports, the CT reviewers found fewer normal and no suspect cases. MRI changed the primary diagnoses in 27 cases, and in 14 and 15 cases, respectively, at review. There was no disagreement on MRI diagnoses. In our patient population, MRI was deemed a more reliable modality for hip fracture diagnosis in comparison to CT. For clinical decision making, MRI seems to have a higher accuracy than CT. A negative CT finding cannot completely rule out a hip fracture in patients where clinical findings of hip fracture persevere. (orig.)

Vijaya R. Bhatt

2014-11-01

Full Text Available Background: Although medical publications are frequently used as the source of information, the prevalence of errata remains unclear. The objective of this study was to examine peer-review and publication processes of medical journals as well as to determine the occurrence of reported errata in medical journals and timeliness in identifying and correcting errata. Methods: Five medical journals, New England Journal of Medicine, Annals of Internal Medicine, British Medical Journal, Journal of American Medical Association, and Lancet, were evaluated. The characteristics of these journals were obtained from editors’ survey. All these journals report errata noted in their prior publications. We retrospectively analyzed all errata reported from January 1, 2012, to December 31, 2012. The mean number of reported errata per issue, the most common errata, and the mean time to report errata were calculated. Results: The journals had high impact factors (14–51, received 3,200 to more than 15,000 submissions in 2012, and utilized two or more external reviewers and usually two or more editors for any accepted articles. All the journals edited the accepted articles, including references, figures, and tables for style. A mean of 1.3 articles with ≥1 errata was reported per issue (a total of 306 articles with errata in 226 issues. Errata in author's information, numeric errata, and errata in the figures and tables were the most common errata. The mean time to report the errata was 122 days. Conclusion: The high-impact journals, with extensive pre-publication review, reported relatively few errata per issue. The delay in reporting errata needs further exploration.

Palmoplantar psoriasis is associated with significant quality-of-life issues. Its epidemiology and phenotypical expression remain ill defined. We reviewed the literature and our clinical experience and developed a new quality-of-life assessment tool. We conducted a retrospective review of 150 patients with palmoplantar psoriasis. In all, 78 (52%) patients displayed predominantly hyperkeratotic palmoplantar lesions, 24 (16%) pustular, 18 (12%) combination, and 30 (20%) had an indeterminate phenotype. In 27 (18%) patients, lesions were confined to the palms and soles. A new quality-of-life index was constructed to characterize disease severity. In all, 27 (18%) had mild, 72 (48%) moderate, and 51 (34%) severe disease involvement. Palmoplantar disease severity appeared independent from the degree of body surface area involvement. This was a retrospective review. The quality-of-life index remains to be statistically verified in prospective clinical studies. Defining morphologic subtypes together with the use of a specific quality-of-life assessment tool in patients with palmoplantar psoriasis will improve our understanding and treatment of this recalcitrant form of psoriasis.

Hip arthroscopy is a minimally invasive alternative to open hip surgery. Despite its minimally invasive nature, there can still be significant reported pain following these procedures. The impact of combined sciatic and lumbar plexus nerve blocks on postoperative pain scores and opioid consumption in patients undergoing hip arthroscopy was investigated. A retrospective analysis of 176 patients revealed that compared with patients with no preoperative peripheral nerve block, significant reductions in pain scores to 24 hours were reported and decreased opioid consumption during the post anesthesia care unit (PACU) stay was recorded; no significant differences in opioid consumption out to 24 hours were discovered. A subgroup analysis comparing two approaches to the sciatic nerve block in patients receiving the additional lumbar plexus nerve block failed to reveal a significant difference for this patient population. We conclude that peripheral nerve blockade can be a useful analgesic modality for patients undergoing hip arthroscopy.

Full Text Available The purpose of this study was to retrospectively review the clinical characteristics and outcomes of a series of women with Paget's disease of the vulva. A retrospective review was performed of 89 women with Paget's disease of the vulva evaluated at a single institution between 1966 and 2010. Medical records were reviewed for demographic information, clinical data, pathologic findings, treatment modalities and outcomes. We found that the primary treatment was surgery for 74 (83.1% patients, with positive margins noted in 70.1% of cases. Five patients (5.6% underwent topical treatment with imiquimod and/or 5-fluorouracil, one patient (1.1% underwent laser ablation and treatment was unknown in 9 patients (10.1%. The majority of patients had multiple recurrences, with 18% having four or more recurrences. There were no significant differences in recurrence rates between patients who underwent surgery and those who did not. Furthermore, there was no association between positive margins following primary surgery and recurrence. Forty-one patients (46.1% were diagnosed with 53 synchronous or metachronous cancers. Seven patients (7.9% were found to have invasive vulvar cancer with 1 mm or more depth of invasion, but none of the patients died of Paget's disease or associated vulvar/vaginal cancer. Our findings suggest that the majority of patients with Paget's disease of the vulva develop multiple recurrences regardless of treatment modality or margin status. Alternatives to surgery are needed to better care for women with this disease.

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

Full Text Available In this study, our aim was to evaluate the antibiotic susceptibility of bacteria isolated from orthopedic implant infections. Within two years operated 1996 patients in an orthopedics and traumatology clinic were retrospectively investigated. Seventy-six (76/1996, 3.8% orthopedic implant infections were detected. Isolated bacteria and their antibiotic susceptibility patterns were analyzed. The bacteries isolated from implant related infections and antibiotic sensitivity patterns were evaluated retrospectively in our orthopaedics and traumatology clinic. Staphylococcus aureus was the predominant organism (30.3%. Gram negative bacterias were isolated in 65.8% of our patients. No resistance was determined against vancomycin and linezolid in gram positive bacterias. Imipenem, amicasin and cefepim was seen as the most effective antibiotics for gram negative bacterias.

Background: Survival rates after curative surgery for gastric cancer are disappointing. Therefore adjuvant therapeutic strategies are required. Aim: To analyze survival and side effects of treatment among gastric cancer patients treated with adjuvant chemoradiotherapy after curative resection of gastric adenocarcinoma. Material and methods: Retrospective review of medical records of 74 patients aged 20 to 74 years, treated with complete resection of gastric adenocarcinoma followed by adjuvant chemo radiation. Survival analysis was based on the records and information from the National Mortality Registry. Results: Five years survival fluctuated from 50% among patients in stage 1B to 25% among those is stage IV. Significant acute toxicity was observed in 23 patients (31%). No patients died due to acute toxicity. Eleven patients (16.4%) developed significant late toxicity, with two possible deaths related to treatment. Conclusions: Postoperative chemoradiotherapy is feasible in our experience. Continuos infusion of 5- fluoruracil is recommended to reduce toxicity

The major aims of this study were to identify factors that may predict the diagnostic conversion from major depressive disorder (MDD) to bipolar disorder (BP) and to evaluate the predictive performance of the bipolar spectrum disorder (BPSD) diagnostic criteria. The medical records of 250 patients with a diagnosis of MDD for at least 5 years were retrospectively reviewed for this study. The diagnostic conversion from MDD to BP was observed in 18.4% of 250 MDD patients, and the diagnostic criteria for BPSD predicted this conversion with high sensitivity (0.870) and specificity (0.917). A family history of BP, antidepressant-induced mania/hypomania, brief major depressive episodes, early age of onset, antidepressant wear-off, and antidepressant resistance were also independent predictors of this conversion. This study was conducted using a retrospective design and did not include structured diagnostic interviews. The diagnostic criteria for BPSD were highly predictive of the conversion from MDD to BP, and conversion was associated with several clinical features of BPSD. Thus, the BPSD diagnostic criteria may be useful for the prediction of bipolar diathesis in MDD patients. Copyright © 2014 Elsevier B.V. All rights reserved.

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

To investigate the diagnostic value of contrast-enhanced computed tomography (CT) for the prediction of deep neck abscesses in different deep neck spaces and to evaluate the false-positive results. We retrospectively analysed the clinical charts, CT examinations, surgical findings, bacteriology, pathological examinations and complications of hospitalised patients with a diagnosis of deep neck abscess from 2004 to 2010. The positive predictive values (PPV) for the prediction of abscesses by CT scan in different deep neck spaces were calculated individually on the basis of surgical findings. A total of 162 patients were included in this study. All patients received both intravenous antibiotics and surgical drainage. The parapharyngeal space was the most commonly involved space. The overall PPV for the prediction of deep neck abscess with contrast-enhanced CT was 79.6%. The PPV was 91.3% when more than one deep neck space was involved but only 50.0% in patients with isolated retropharyngeal abscesses. In the false-positive group, cellulitis was the most common final result, followed by cystic degeneration of cervical metastases. Five specimens taken intra-operatively revealed malignancy and four of these were not infected. There are some limitations affecting the differentiation of abscesses and cellulitis, particularly in the retropharyngeal space. A central necrotic cervical metastatic lymph node may sometimes also mimic a simple pyogenic deep neck abscess on both clinical pictures and CT images. Routine biopsy of the tissue must be performed during surgical drainage.

Full Text Available Abstract Background Hyponatremia is the most common electrolyte disorder in hospitalized patients and is known to be associated with increased mortality. The administration of antegrade single-shot, up to two liters, histidine-tryptophane-ketoglutarate (HTK solution for adequate electromechanical cardiac arrest and myocardial preservation during minimally invasive aortic valve replacement (MIAVR is a standard procedure. We aimed to determine the impact of HTK infusion on electrolyte and acid–base balance. Methods In this retrospective analysis we reviewed data on patient characteristics, type of surgery, arterial blood gas analysis during surgery and intra-/postoperative laboratory results of patients receiving surgery for MIAVR at a large tertiary care university hospital. Results A total of 25 patients were included in the study. All patients were normonatremic at start of surgery. All patients developed hyponatremia after administration of HTK solution with a significant drop of serum sodium of 15 mmol/L (p  Conclusions Acute hyponatremia during cardioplegia with HTK solution is isotonic and should probably not be corrected without presence of hypotonicity as confirmed by measurement of serum osmolality.

A retrospective multicenter case-series study; case report and review of the literature. The anatomy and function of the superior laryngeal nerve (SLN) are well described; however, the consequences of SLN injury remain variable and poorly defined. The prevalence of SLN injury as a consequence of cervical spine surgery is difficult to discern as its clinical manifestations are often inconstant and frequently of a subclinical degree. A multicenter study was performed to better delineate the risk factors, prevalence, and outcomes of SLN injury. A retrospective multicenter case-series study involving 21 high-volume surgical centers from the AO Spine North America Clinical Research Network. Medical records for 17 625 patients who received subaxial cervical spine surgery from 2005 to 2011 were reviewed to identify occurrence of 21 predefined treatment complications. Descriptive statistics were provided for baseline patient characteristics. A retrospective review of the neurosurgical literature on SLN injury was also performed. A total of 8887 patients who underwent anterior cervical spine surgery at the participating institutions were screened, and 1 case of SLN palsy was identified. The prevalence ranged from 0% to 1.25% across all centers. The patient identified underwent a C4 corpectomy. The SLN injury was identified after the patient demonstrated difficulty swallowing postoperatively. He underwent placement of a percutaneous gastrostomy tube and his SLN palsy resolved by 6 weeks. This multicenter study demonstrates that identification of SLN injury occurs very infrequently. Symptomatic SLN injury is an exceedingly rare complication of anterior cervical spine surgery. The SLN is particularly vulnerable when exposing the more rostral levels of the cervical spine. Careful dissection and retraction of the longus coli may decrease the risk of SLN injury during anterior cervical surgery.

Phenytoin (PH) is indicated primarily for the control of grand mal and psychomotor seizures. However, topical PH has been used for the treatment of various types of ulcers, including pressure ulcers. The aim of this study was to investigate the possibility of a relationship between the use of oral PH and the prevalence of pressure ulcers among bedridden institutionalized elderly patients. This retrospective chart review was conducted in a state-run urban geriatric medical center in Israel and involved long-term bedridden institutionalized patients who were receiving chronic antiepileptic medication during the 7-year period between January 1996 and December 2003. The prevalence of pressure ulcers in patients who received treatment with PH alone or in combination with other antiepileptic drugs was compared with that in patients who received antiepileptic agents other than PH. The study analyzed data from the medical charts of 153 patients, 72 of whom received PH alone or in combination with other antiepileptic drugs, and 81 of whom received antiepileptic agents other than PH. Patients' mean (SD) age was 78.5 (7.2) years; 106 (69.3%) were women. All patients were totally dependent with respect to activities of daily living (mean Katz score, 2.0 [2.0]) and had severe cognitive decline (mean Mini-Mental State Examination score, 3.5 [3.3]). Pressure ulcers occurred in 9.7% of PH recipients and 27.2% of non-PH recipients (P = 0.006; chi2 = 7.55). In PH recipients, 85.7% of pressure ulcers were of mild to moderate severity (stage I or II), compared with 59.1% of ulcers in non-PH recipients; the difference between groups was not statistically significant. Four (18.2%) non-PH recipients and no PH recipients had stage IV pressure ulcers. In the PH group, 71.4% of patients had a pressure ulcer in only 1 anatomic location, compared with 22.7% of the non-PH group (P = 0.023; chi2 = 5.13); 28.6% of PH recipients and 63.6% of non-PH recipients had pressure ulcers in 2 or 3

2008-09-01

Morphea is an autoimmune inflammatory sclerosing disorder that may cause permanent functional disability and disfigurement. We sought to determine the clinical features of morphea in a large pediatric cohort. We conducted a retrospective chart review of 136 pediatric patients with morphea from one center, 1989 to 2006. Most children showed linear morphea, with a disproportionately high number of Caucasian and female patients. Two patients with rapidly progressing generalized or extensive linear morphea and arthralgias developed restrictive pulmonary disease. Initial oral corticosteroid treatment and long-term methotrexate administration stabilized and/or led to disease improvement in most patients with aggressive disease. Retrospective analysis, relatively small sample size, and risk of a selected referral population to the single site are limitations. These data suggest an increased prevalence of morphea in Caucasian girls, and support methotrexate as treatment for problematic forms. Visceral manifestations rarely occur; the presence of progressive problematic cutaneous disease and arthralgias should trigger closer patient monitoring.

Laparoscopic and vaginal hysterectomies are common gynaecological procedures. Same-day discharge is usual care in various gynaecological procedures like laparoscopic sterilisation and laparoscopic oophorectomies. In major procedures like vaginal or laparoscopic hysterectomy patients are usually admitted overnight. We systematically reviewed the literature to identify complications, risk factors for (re)admittance, financial consequences and patient satisfaction of same-day discharge after a vaginal or laparoscopic hysterectomy. We systematically searched PubMed, UptoDate, Embase, Cochrane and CINAHL database from inception until July 16th 2016. We selected randomized controlled trials, prospective and retrospective cohort studies assessing the safety and feasibility of same-day discharge after vaginal or laparoscopic hysterectomy. The outcome parameters that were assessed were admission rate, re-admission rate, minor and major complications, patient satisfaction and financial consequences. 27 articles were included in the systematic review. All studies provided data about the admission rate and therefore failure of same-day discharge. Eleven prospective studies were included which compromised a total of 2391 hysterectomies. The percentage of overnight admissions was median 9.3% [0-25%]. Eight retrospective studies, which screened their patients before undergoing an outpatient hysterectomy, showed in 1500 subjects a mean admission rate of 10% [4,4-64%]. Four retrospective studies, which considered a large total cohort of 142,799 hysterectomies had a mean admission rate of 59,7% [48-79%]. The overall re-admission rate was low, varying from 0.73-4.0%. Minor complications were reported in respectively 4,3% and 7,3% in prospective respectively retrospective trials. Major complications were described in 0.7%-3.6% of all cases. Generally high satisfaction rates were reported in the observational trials. Same-day discharge after laparoscopic and vaginal hysterectomy seems

Computed tomography of the kidneys, ureters and bladder is the recommended imaging modality for suspected urolithiasis. Early scanning is advised in guidelines, but there is limited published evidence to support this recommendation. In a retrospective study, we reviewed patients managed according to a local guideline. Patients without high-risk features were either imaged during their initial visit (if in the daytime) or discharged for outpatient scans. Complications, unplanned returns, final diagnosis, and intervention rates were compared between groups. Fifty-four patients were scanned during their initial visit and 151 were scanned as an outpatient at a median interval of 10 days. Unplanned return rates were lower in those scanned as outpatients (7.3 vs. 24.1%), with no significant difference in complications (2.0 vs. 3.7%; none leading to permanent harm). Those scanned as outpatients were less likely to have a stone proven by imaging (39.7 vs. 64.8%), but did not have a significantly higher rate of proven alternative diagnosis (9.3 vs. 13.0%). There is no evidence in this cohort that discharging patients for outpatient imaging is associated with poorer outcomes, provided that an appropriate clinical risk assessment is carried out.

Nowadays, the entire manufacturing process is based on the current GMPs, which emphasize the reproducibility of the process, and companies have a lot of recorded data about their processes. The establishment of the design space (DS) from retrospective data for a wet compression process. A design of experiments (DoE) with historical data from 4 years of industrial production has been carried out using the experimental factors as the results of the previous risk analysis and eight key parameters (quality specifications) that encompassed process and quality control data. Software Statgraphics 5.0 was applied, and data were processed to obtain eight DS as well as their safe and working ranges. Experience shows that it is possible to determine DS retrospectively, being the greatest difficulty in handling and processing of high amounts of data; however, the practicality of this study is very interesting as it let have the DS with minimal investment in experiments since actual production batch data are processed statistically.
