    Background This study is an attempt to clarify the role of C-reactive protein (CRP) as a surgical indication marker for appendicitis. Methods One hundred and fifty patients who underwent appendectomies and had pathologically confirmed appendicitis were reviewed between May 1, 1999 and September 31, 2007. The correlation between preoperative clinical factors and the actual histological severity, and identify surgical indication markers were assessed by univariate and multivariate analyses. Results Univariate analysis showed that only the CRP level significantly differ between the surgical treatment necessary group (gangrenous appendicitis) and the possible non-surgical treatment group (catarrhalis and phlegmonous appendicitis). Multivariate analysis indicated only the CRP level to be a surgical indication marker for acute appendicitis. The receiver-operating characteristic (ROC) curve indicated that the cutoff value of CRP for surgical indication of appendicitis is 4.95 mg/dl. Conclusion Only the CRP level is consistent with the severity of appendicitis, and considered to be a surgical indication marker for acute appendicitis. PMID:19878592

    The recurrence rate for acute appendicitis treated nonoperatively varies between studies. Few studies have adequately evaluated the management of these patients when appendicitis recurs. We aimed to explore the recurrence rate and management of patients with acute appendicitis that were first treated nonoperatively.We identified patients in the Taiwan National Health Insurance Research Database who were hospitalized due to acute appendicitis for the first time between 2000 and 2010 and received nonsurgical treatment. The recurrence and its management were recorded. Data were analyzed to access the risk factors for recurrence and factors that influenced the management of recurrent appendicitis.Among the 239,821 patients hospitalized with acute appendicitis for the first time, 12,235 (5.1%) patients were managed nonoperatively. Of these, 864 (7.1%) had a recurrence during a median follow-up of 6.5 years. Appendectomy was performed by an open and laparoscopic approach in 483 (55.9%) and 258 (29.9%) patients, respectively. The remaining 123 (14.2%) patients were again treated nonsurgically. Recurrence was independently associated with young age, male sex, percutaneous abscess drainage, and medical center admission by multivariable analysis. In addition, age appendicitis, percutaneous abscess drainage, nor length of first time hospital stay had an influence on the selection of surgical approach.In conclusion, a laparoscopic appendectomy can be performed in recurrent appendicitis cases, and its application may not be related to previous appendicitis severity.

    Full Text Available Background: Acute appendicitis (AA is the most common surgical emergency in childhood. The risk of rupture is negligible within the first 24 h, climbing to 6% after 36 h from the onset of symptoms. Because of difficulty in accurate diagnosis of AA a significant number of children still are being managed when it is already perforated. There is always a need to make an early diagnosis of AA and to find out the risk factors associated with development of complication in this condition. Patients and Methods: A total of 102 patients with a clinical diagnosis of AA were admitted during the study period. On admission, a good clinical history and proper physical examination was performed. All the eligible patients who finally diagnosed clinically as having AA were planned for emergency open appendectomy. The removed appendix was sent for histopathological examination in all the study subjects. Results: Out of 102 cases, 93 cases were histopathologically appendicitis, rest nine cases showed no evidence of inflammation so the rate of negative appendectomy was around 9%. On histopathology normal appendix was found in nine patients (8.9%, AA in 71 patients (69.6%, complicated appendicitis (CA which includes perforated and gangrenous appendicitis was present in 22 patients (21.5%. Perforations were more common in patients who were younger than 5 years. >60% patients presented with CA when the duration of pain was >72 h. Presence of appendicolith increased the probability of CA.

    Full Text Available Appendicitis is a common surgical emergency and diagnosis is still a great challenge. Accurate diagnosis and timely intervention re-duces morbidity and mortality. The present study was conducted to evaluate Alvarado scoring system for diagnosis of acute appen-dicitis in Indian set up. The study was carried out on 200 patients admitted in Surgery ward between January 2009 and December 2010 with right lower quadrant abdominal pain. Alvarado score was calculated and all patients were divided in three groups. Mean age of presentation was 29.12 years and male to female ratio was 1.27:1. Higher the Alvarado score, more is the sensitivity. So pa-tients having score 7 or above had sensitivity of 66%. We con-clude that Alvarado score is unique since it incorporates signs, symptoms and laboratory findings of suspicious patients. Alvarado score can be utilized safely for diagnosis of acute appendicitis.

    Full Text Available Digital rectal examination (DRE has been traditionally recommended to evaluate acute appendicitis, although several reports indicate its lack of utility for this diagnosis. No meta-analysis has examined DRE for diagnosis of acute appendicitis.To assess the role of DRE for diagnosis of acute appendicitis.Cochrane Library, PubMed, and SCOPUS from the earliest available date of indexing through November 23, 2014, with no language restrictions.Clinical studies assessing DRE as an index test for diagnosis of acute appendicitis.Two independent reviewers extracted study data and assessed the quality, using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Bivariate random-effects models were used for the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio (DOR as point estimates with 95% confidence intervals (CI.The main outcome measure was the diagnostic performance of DRE for diagnosis of acute appendicitis.We identified 19 studies with a total of 7511 patients. The pooled sensitivity and specificity were 0.49 (95% CI 0.42-0.56 and 0.61 (95% CI 0.53-0.67, respectively. The positive and negative likelihood ratios were 1.24 (95% CI 0.97-1.58 and 0.85 (95% CI 0.70-1.02, respectively. The DOR was 1.46 (0.95-2.26.Acute appendicitis cannot be ruled in or out through the result of DRE. Reconsideration is needed for the traditional teaching that rectal examination should be performed routinely in all patients with suspected appendicitis.

    BACKGROUND: The classification of acute appendicitis (AA) into various grades is not consistent, partly because it is not clear whether the perioperative or the histological findings should be the foundation of the classification. When comparing results from the literature on the frequency...... patients were included. In 116 (89 %) of these cases, appendicitis was confirmed histological. There was low concordance between the perioperative and histological diagnoses, varying from 16 to 76 % depending on grade of AA. Only 44 % of the patients receiving antibiotics postoperatively had a positive...... peritoneal fluid cultivation. CONCLUSION: There was a low concordance in clinical and histopathological diagnoses of the different grades of appendicitis. Perioperative cultivation of the peritoneal fluid as a standard should be further examined. The potential could be a reduced postoperative antibiotic use...

    There are many differences between acute appendicitis in the older child and the infants. An understanding of the under three years of age child's response to intra-abdominal infection in contrast to that of the older child and an appreciation for the supportive treatment of the child are vitally important in further lowering the morbidity of young children with acute appendicitis. The purpose of the present study was to investigate the factors contributing to the high perforation rate seen in this age group. A retrospective analysis was done in 88 patients under the age of three who underwent appendectomy. These patients ranged from 4 and 35 months in age. There were 51 (77.4%) male patients. The main complaints were fever, pain and vomiting. Duration of symptoms was more than 24 hours in 80%. Abdominal radiographs showed signs of small bowel obstruction. Peritonitis was found in the majority of the cases (90%). overall morbidity was 31.8% and mortality 1.1%. These data suggest that duration of symptoms is directly proportional to complications rate.

    To identify MRI features associated with appendicitis. Features expected to be associated with appendicitis were recorded in consensus by two expert radiologists on 223 abdominal MRIs in patients with suspected appendicitis. Nine MRI features were studied: appendix diameter >7 mm, appendicolith, peri-appendiceal fat infiltration, peri-appendiceal fluid, absence of gas in the appendix, appendiceal wall destruction, restricted diffusion of the appendiceal wall, lumen or focal fluid collections. Appendicitis was assigned as the final diagnosis in 117/223 patients. Associations between imaging features and appendicitis were evaluated with logistic regression analysis. All investigated features were significantly associated with appendicitis in univariate analysis. Combinations of two and three features were associated with a probability of appendicitis of 88 % and 92 %, respectively. In patients without any of the nine features, appendicitis was present in 2 % of cases. After multivariate analysis, only an appendix diameter >7 mm, peri-appendiceal fat infiltration and restricted diffusion of the appendiceal wall were significantly associated with appendicitis. The probability of appendicitis was 96 % in their presence and 2 % in their absence. An appendix diameter >7 mm, peri-appendiceal fat infiltration and restricted diffusion of the appendiceal wall have the strongest association with appendicitis on MRI. (orig.)

    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.

    The objective of our study was to estimate the complementary role of ultrasound evaluation in the diagnosis of acute appendicitis after abdominoplevic CT. A total of 104 patients initially underwent abdominopelvic CT before appendix US due to acute abdominal pain. All CT examinations were evaluated retrospectively for the presence of acute appendicitis. The findings of appendix on CT were classified into five categories (definite appendicitis, probably appendicitis, equivocal CT findings for diagnosis of appendicitis, probably not appendicitis, and normal looking appendix). Appendix US images and their radiologic reports were also evaluated retrospectively. Then, CT and US findings were correlated with clinical or pathologic diagnosis. Three all patients with definite appendicitis initially on CT again showed US findings of appendicitis. In the 32 patients of probably appendicitis on CT, US showed normal looking appendix in seven patients (21.8%, 7 of 32) who improved with medical treatment and discharged. In the 16 patients of equivocal CT findings for diagnosis of appendicitis, US showed appendicitis in seven patients (43.8%, 7 of 16) and normal looking appendix in nine patients. In the 12 patients of probably not appendicitis on CT, US showed acute appendicitis in two patients (16.7%, 2 of 12). In the 41 patients of normal looking appendix on CT, US showed acute appendicitis in five patients (12.2%, 5 of 41). US reevaluation enables us to avoid misdiagnosis of appendicitis on CT and improve diagnostic accuracy of acute appendicitis.

    To investigate the significance of intra-appendiceal air at CT for the evaluation of appendicitis. We retrospectively analyzed 458 patients (216 men, 242 women; age range, 18-91 years) who underwent CT for suspected appendicitis. Two independent readers reviewed the CT. Prevalence, amount, and appearance of intra-appendiceal air were assessed and compared between the patients with and without appendicitis. Performance of CT diagnosis was evaluated in two reading strategies: once ignoring appendiceal air (strategy 1), and the other time considering presence of appendiceal air as indicative of no appendicitis in otherwise indeterminate cases (strategy 2), using receiver operating characteristic (ROC) analysis. Of the 458 patients, 102 had confirmed appendicitis. The prevalence of intra-appendiceal air was significantly different between patients with (13.2%) and without (79.8%) appendicitis (p < 0.001). The amount of appendiceal air was significantly lesser in patients having appendicitis as compared with the normal group, for both reader 1 (p = 0.011) and reader 2 (p = 0.002). Stool-like appearance and air-fluid levels were more common in the appendicitis group than in the normal appendix for both readers (p < 0.05). Areas under the ROC curves were not significantly different between strategies 1 and 2 in reader 1 (0.971 vs. 0.985, respectively; p = 0.056), but showed a small difference in reader 2 (0.969 vs. 0.986, respectively; p = 0.042). Although significant differences were seen in the prevalence, amount, and appearance of intra-appendiceal air between patients with and without appendicitis, it has a limited incremental value for the diagnosis of acute appendicitis.

    Full Text Available Appendicitis is one of the commonest causes of abdominal pain requiring surgery. Early diagnosis and management are essential to reduce morbidity and mortality. Imaging is valuable in the diagnosis of cases that are clinically atypical. Imaging also allows evaluation of the complications of appendicitis. In certain circumstances, conservative treatment of complicated appendicitis with percutaneous drainage is appropriate.

    Full Text Available Appendicitis is an acute inflammatory condition of appendix. Since it is a surgical emergency, needs early diagnosis and treatment strategies which include clinical examination, followed by Laboratory investigations and Imaging studies. The scoring systems like Alvarado score have been considered for better diagnosis. In most studies surgery has been reported as the best modality of treatment. Several studies clearly mentioned the impact of various surgical procedures which include Open appendectomy (OA, Conventional laparoscopic appendectomy (CLA and Single incision laparoscopic appendectomy (SILA. Hence, the present study is carried in an aim to assess and compare the merits and demerits between the surgical procedures Like SILA and CLA. The patients were randomly selected from the surgical department (NMCH who presented with acute pain abdomen and diagnosed as acute appendicitis. 50 patients were enrolled in the study after fulfilling the inclusion and exclusion criteria. The various demographic variables have been studied between the surgical procedures to demonstrate their impact, which include wound infection rate, pain scores at 24 and 48hrs, the amount of time period for surgery in minutes, patient satisfaction scores and post-operative stay tenure at the hospital in days. The laparoscopic hand instruments used in both techniques are similar, except covidien port which was reused in SILA, following gas sterilization to reduce the cost. Findings reveal that the pain score was significantly lower in SILA than CLA group. The procedure time is comparatively more in SILA than CLA group. Patients had significant satisfaction score in SILA measured at 6 weeks after appendectomy. However the post operative stay, wound infection rate was almost similar in both the groups. There was no conversion to open Appendectomy performed in either of these groups. Results also clearly suggest that the SILA procedure is the safe, alternative and effective

The mean PAS was lower among the younger compared with the older patients (5.3 and 6.6, resp.; P=0.005, despite the fact that younger children had more severe appendicitis (75.0% and 33.3%, resp.; P=0.001. PAS had low sensitivity in both groups, with a significantly lower sensitivity among the younger patients. Parent and doctor delay were confirmed in children <4 years of age with appendicitis. PAS did not aid in patients with doctor delay. Parameters in patient history, symptoms, and abdominal examination were more diffuse in younger children. Conclusion. PAS should be used with caution when examining children younger than 4 years of age. Diffuse symptoms in younger children with acute appendicitis lead to delay and to later diagnosis and more complicated appendicitis.

    The authors have done a biliary retrospective analysis of 10 deceased patients with a diagnosis of biliary peritonitis (BP). It is reported that the patients who died of BP are 9.5% of all who died of diffuse purulent peritonitis. All deceased patients were advanced and well advanced in years with prolonged complaints--in over 50% of them over 5 years. The complications set in 50% of the cases are recorded in the postoperative period. The perforation of the gallbladder and the biliopancreatitis are in the second place. Intrabiliary fistulas with 4 patients and 1 with a vesicocolon fistula; tumor of the pancreas with 4 patients; empyema of the gallbladder--3; diabetes with 3 of the patients and others are recorded as accompanying troubles which complicate the operation and the outcome of it. The time between the beginning of the complication and the operation with all the deceased patients is over 72 hours.

    AIM To review clinical experience with barium appendicitis at a single institution. METHODS A retrospective review of patients admitted with a diagnosis of acute appendicitis, from January 1, 2013 to December 31, 2015 was performed. Age, gender, computed tomography (CT) scan findings if available, past history of barium studies, pathology, and the presence of perforation or the development of complications were reviewed. If the CT scan revealed high density material in the appendix, the maximum CT scan radiodensity of the material is measured in Hounsfield units (HU). Barium appendicitis is defined as: (1) patients diagnosed with acute appendicitis; (2) the patient has a history of a prior barium study; and (3) the CT scan shows high density material in the appendix. Patients who meet all three criteria are considered to have barium appendicitis. RESULTS In total, 396 patients were admitted with the diagnosis of acute appendicitis in the study period. Of these, 12 patients (3.0%) met the definition of barium appendicitis. Of these 12 patients, the median CT scan radiodensity of material in the appendix was 10000.8 HU, ranging from 3066 to 23423 HU (± 6288.2). In contrast, the median CT scan radiodensity of fecaliths in the appendix, excluding patients with barium appendicitis, was 393.1 HU, ranging from 98 to 2151 HU (± 382.0). The CT scan radiodensity of material in the appendices of patients with barium appendicitis was significantly higher than in patients with nonbarium fecaliths (P < 0.01). CONCLUSION Barium appendicitis is not rare in Japan. Measurement of the CT scan radiodensity of material in the appendix may differentiate barium appendicitis from routine appendicitis.

    Full Text Available Introduction: Many of the treatment modalities recommended for acromegaly are either too expensive or not available in large parts of India. There is a dearth of treatment and outcome data in Indian patients. Aims and Objectives: The purpose of this study was to analyze the treatment modalities used and the respective outcomes which include remission, recurrence, hypopituitarism, other complications, and mortality. Materials and Methods: This is a retrospective data analysis of 15 acromegaly patients treated at a tertiary care hospital in eastern India. A remission criteria of nadir growth hormone level <1 μg/dl after Oral Glucose tolerance test (OGTT and normal age related IGF-1 levels was used. Results: All patients (100% had macroadenomas. Surgery could not be done in five (33%; three (19.8% refused, two (13.2% had comorbidities. Transsphenoidal surgery (TSS achieved remission in four out of ten (40%. Conventional radiotherapy (CRT failed in all five patients and caused hypopituitarisn in three (60%. Cabergoline (CAB either alone or following surgery achieved remission in one out of four (25% though symptomatic relief and tolerability were remarkable. One patient (7% had pituitary apoplexy with remission, two patients (14.3% died due to CVA. Conclusions: TSS remains the treatment of choice in acromegaly, though in macroadenomas the success is limited. A sizeable proportion of patients refuse or are unfit for surgery. As most of the recommended options are very costly or unavailable, alternative treatment options generally used are CRT or CAB which have limited efficacy. Incidence of hypopituitarism, following CRT is very high.

    Full Text Available BACKGROUND Laryngeal cancer is the second most common head and neck cancer in India. The onset, rate of progression and duration of symptoms are variable for supraglottic, glottic and subglottic cancer. Smoking and alcohol are also most important risk factors for laryngeal cancer. Data regarding cases of laryngeal cancer in relation to age, sex, symptoms and signs, aetiological factors with special reference to smoking and alcohol, histopathological types, tumour staging, treatment and outcomes are important to assess changing trends in laryngeal cancer treatment. MATERIALS AND METHODS This study is about retrospective descriptive analysis of diagnosed and treated cases of laryngeal cancer in the Department of ENT from 2005 to 2008. Total fifty patients with laryngeal malignancy were seen from May 2005 to May 2008 with average 1 year of follow-up. Data regarding cases of laryngeal cancer in relation to age, sex, symptoms and signs, aetiological factors with special reference to smoking and alcohol, histopathological types, tumour staging, treatment and outcomes were analysed using SPSS software. All patients who were diagnosed to have laryngeal cancer and treated were included in the study. RESULTS In this descriptive analysis, 62% patients are between 51-70 years. Most of the patients had been symptomatic for 3-5 months; 58% patients presented with voice change followed by other complaints like throat pain, foreign body sensation, otalgia, breathing difficulty. Voice change was distinctly the most common symptom regardless of tumour site. It was more prevalent in glottis cases, but it was also the leading symptom in supraglottic tumours. Glottis tumours were more often found at an early stage and patients with a supraglottic tumour presented more often with neck node metastasis. CONCLUSION Laryngeal malignancy is one of the head and neck malignancies, which are more common in males. Tobacco is an important risk factor in causation of the

  13. Influence of delays on perforation risk in adults with acute appendicitis.

    2012-02-03

    PURPOSE: This study analyzed whether prehospital or in-hospital delay was the more significant influence on perforation rates for acute appendicitis and whether any clinical feature designated patients requiring higher surgical priority. METHODS: A retrospective analysis was conducted over one year at a tertiary referral hospital without a dedicated emergency surgical theater. Admission notes, theater logbook, and the Hospital Inpatient Enquiry system were reviewed to identify the characteristics and clinical course of patients aged greater than 16 years who were operated upon for histologically confirmed acute appendicitis. RESULTS: One hundred and fifteen patients were studied. The overall perforation rate was 17 percent. The mean duration of symptoms prior to hospital presentation was 38.1 hours with the mean in-hospital waiting time prior to operation being 23.4 hours. Although body temperature on presentation was significantly greater in patients found to have perforated appendicitis (P < 0.05), only patient heart rate at presentation and overall duration of symptoms, but not in-hospital waiting time, independently predicted perforation by stepwise linear regression modeling. CONCLUSION: In-hospital delay was not an independent predictor of perforation in adults with acute appendicitis although delays may contribute if patients are left to wait unduly. Tachycardia at presentation may be a quantifiable feature of those more likely to have perforation and who should be given higher surgical priority.

    Full Text Available This study evaluated bacterial etiology and antibiotic susceptibility in patients diagnosed with community-acquired perforated appendicitis over a 12-year-period. We retrospectively reviewed records of adult patients diagnosed with perforated appendicitis at an 800-bed teaching hospital between January 2000 and December 2011. In total, 415 culture-positive perforated appendicitis cases were analyzed. Escherichia coli was the most common pathogen (277/415, 66.7%, followed by Streptococcus species (61/415, 14.7%. The susceptibility of E. coli to ampicillin, piperacillin/tazobactam, ceftriaxone, cefepime, amikacin, gentamicin, and imipenem was 35.1%, 97.1%, 97.0%, 98.2%, 98.9%, 81.8%, and 100%, respectively. The overall susceptibility of E. coli to quinolones (ciprofloxacin or levofloxacin was 78.7%. During the study period, univariate logistic regression analysis showed a significant decrease in E. coli susceptibility to quinolones (OR = 0.91, 95% CI 0.84-0.99, P = 0.040. We therefore do not recommend quinolones as empirical therapy for community-acquired perforated appendicitis.

    Objective Mastalgia is the most common symptom in women, who has gone under breast imaging. 70% of women face with mastalgia at least once in their lifetime. In our study, we aimed to investigate the examinations and the results of the females referred to our outpatient clinics with mastalgia and to determine the frequency of malignancy. Materials and Methods Files of all women patients referred to General Surgery Outpatient Clinics between 01.06.2014–31.05.2015 has been investigated retrospectively. Cases only with breast pain complaint (n=789) out of 2798 women has been included in the study. Women with lump in breast, nipple discharge, redness, breast retraction and pregnant and lactating women were excluded. Breast examination findings, ultrasonography (USG), mammography results, whether biopsies are done or not and diagnoses have been investigated retrospectively. Results Mean age was 42.97±12.36 (16–74) years. 59.7% (n=471) of the women had bilateral mastalgia and 91.1% (n=719) of the breast examinations were found to be normal. USG was required from 664 (84.2%) women and mammography was required from 448 (56.8%) women. Considering diagnoses; fibrocystic changes in 32.3% (n=201), ductal ectasia in 8.8% (n=55), fibroadenomas in 6.1% (n=38), reactive lymphoid hyperplasia in 1.1% (n=7) was observed. Only 1 (0.2%) woman was diagnosed with invasive ductal carcinoma. Conclusion According to researches, 0.5% of the women with mastalgia were diagnosed with breast cancer. In our study this rate was found as 0.2%. Women with only mastalgia without any abnormality in physical examination should be informed about dealing with pain. PMID:28331753

    Background Appendicitis is the most common surgical problem in pregnancy, however the particular dangers of appendicitis in pregnancy lie in the varied presentation of symptoms and the higher chance of delayed diagnosis. The aim of this study was to determine the risk factors associated with prenatal outcome in acute appendicitis during second and third trimester pregnancies.Methods This was a retrospective single-center study that presented a descriptive analysis of the results. A total of 102 pregnant women who were diagnosed with acute appendicitis and operated upon in Peking University Third Hospital,China between January 1993 and December 2007 were presented. SPSS 12.0 for Windows was used for data analysis.Results Seventy-eight pregnant women who were diagnosed with acute appendicitis (sixteen patients had a perforated appendix, 62 patients had a non-perforated appendix) were operated upon during late pregnancy. The interval between symptom onset and surgery was the only predictive variable. A longer interval between symptom onset and surgery was associated with appendix perforation ((109.5±52.7) hours) than with no appendix perforation ((35.1±19.62) hours;P=0.007). There was a significant difference in the rate of preterm labor (5.1% vs 1.3%) and the rate of fetal mortality (25% vs 1.7%) between patients with and without a perforated appendix.Conclusions Delaying surgery correlates to more advanced disease with an increased risk of perforation. This contributes to an increased risk of further complications, including premature labor or abortion, and to higher maternal complication rates. Prompt diagnosis may improve the prenatal outcome.

    Objective:To investigate the relation between fruit seeds, plants residuals and appendicitis. Methods: Among cases that underwent appendectomy, the appendicitis cases having fruit seeds and undigested plant residuals in their etiology were examined retrospectively. Also, histopathological features, age, sex, and parameters of morbidity and mortality were used. Results: Fruit seed was found in one case(0.05%) with presence of pus in appendix lumen, undigested plant residuals in 7 cases(0.35%). It was determined that there were appendix inflammation in 2 of the plant residuals cases, while there were obstruction and lymphoid hyperplasia in the appendix lumen of5 cases. No mortality was observed.Conclusions: The ratio of acute appendicitis caused by plants is minimal among all appendectomised patients, but avoidence of eating undigested fruit seeds and chewing plants well may help to prevent appendicitis.

    Appendectomy is one of the most frequently performed operations. Stump appendicitis, as a postoperative complication of appendectomy, is inflammation of the remnant residue when an incomplete excision occurs. We present a patient with stump appendicitis who had been operated on, laparoscopically, for acute appendicitis 6 months before. The patient was diagnosed with acute appendicitis, underwent surgery, and was discharged on postoperative day 3 without complications. Stump appendicitis is a rare cause of acute abdominal disease but should be considered in the differential diagnosis. Ultrasonography is helpful in the diagnosis.

    Full Text Available Abstract Purpose This retrospective study was done to better understand the conditions for which stereotactic radiosurgery (SRS for glioblastoma may be efficacious. Methods Between 2000 and 2007, 33 patients with a pathological diagnosis of glioblastoma received SRS with the Novalis® Shaped Beam Radiosurgery system. Eighteen patients (54% underwent salvage SRS for recurrence while 15 (45% patients received upfront SRS following standard fractionated RT for newly diagnosed glioblastoma. Results There were no RTOG grade >2 acute side effects. The median survival after SRS was 6.7 months (range 1.4 – 74.7. There was no significant difference in overall survival (from the time of initial diagnosis with respect to the timing of SRS (p = 0.2. There was significantly better progression free survival in patients treated with SRS as consolidation versus at the time of recurrence (p = 0.04. The majority of patients failed within or at the margin of the SRS treatment volume (21/26 evaluable for recurrence. Conclusion SRS is well tolerated in the treatment of glioblastoma. As there was no difference in survival whether SRS is delivered upfront or at recurrence, the treatment for each patient should be individualized. Future studies are needed to identify patients most likely to respond to SRS.

    Full Text Available Aim: The prevalence of epilepsy is higher in Nepal. This study was conducted to analyze the clinical manifestations of neurocysticercosis (NCC among seizure patients admitted to our center. Methods: We retrospectively studied all the NCC patients admitted to Neurology Department, Bir Hospital, Kathmandu, Nepal from April 2012 to February 2014. Computer tomography/magnetic resonance imaging (CT/MRI head, clinical profile, lab investigations and exclusion of other causes were the basis of the NCC diagnosis. Chi-square and Student′s t-test were used for comparison of variables. Results: Out of 131 seizure patients admitted, 21 patients were diagnosed with NCC (mean age: 33.95 ± 16.41; male: 15 (71.4%, female: 6 (28.6%. Generalized tonic clonic seizure was the most common seizure type in NCC patients (18 patients; 85.7%, two of them had status epilepticus during presentation in Emergency Department. Three patients had focal seizure, one with epilepsia partialis continua. Neuroimaging showed multiple NCC lesions in 8 (38.1% and a single NCC lesion in 13 (61.9% patients. Seven of them (33.3% sought traditional healers before being presented to our center. Eight patients (38.1% were treated with antiepileptics in local health-post without neuroimaging studies done. Calcified stage of NCC was the most frequent CT/MRI findings (12 patients; 57.1%. Phenytoin was preferred both by physicians and patients due to its low cost. Conclusion: NCC is a common finding among seizure patients in Nepal. Poor economic status, illiteracy and underdeveloped rural society are the major challenges in prevention and treatment of NCC.

    Full Text Available Background: There are a few studies reporting the long term outcome of conservatively treated acetabular fractures. The present study aims to evaluate the quality of reduction, and radiological and functional outcome in displaced acetabular fractures treated conservatively. Materials and Methods: Sixty-nine patients (55 men and 14 women with 71 displaced acetabular fractures (mean age 38.6 years managed conservatively were retrospectively evaluated. There were 11 posterior wall, 5 posterior column, 6 anterior column, 13 transverse, 2 posterior column with posterior wall, 9 transverse with posterior wall, 6 T-shaped, 1 anterior column with posterior hemi-transverse, and 18 both-column fractures. The follow-up radiographs were graded according to the criteria developed by Matta J. Functional outcome was assessed using Harris hip score and Merle d′Aubigne and Postel score at final followup. Average follow-up was 4.34 years (range 2-11 years. Results: Patients with congruent reduction (n=45 had good or excellent functional outcome. Radiologic outcome in incongruent reduction (n=26 was good or excellent in 6 and fair or poor in 20 hips. The functional outcome in patients with incongruent reduction was good or excellent in 16 and satisfactory or poor in 10 hips. Good to excellent radiologic and functional outcome was achieved in all patients with posterior wall fractures including four having more than 50% of broken wall. Good to excellent functional outcome was observed in 88.8% of both-column fractures with secondary congruence despite medial subluxation. Conclusions: Nonoperative treatment of acetabular fractures can give good radiological and functional outcome in congruent reduction. Posterior wall fractures with a congruous joint without subluxation on computed tomography axial section, posterior column, anterior column, infratectal transverse or T-shaped, and both-column fractures may be managed conservatively.

    Full Text Available We planned this study with the aim of determining histological types, clinical, surgical stage and grade of endometrial cancer cases which were followed-up and operated on in our clinic and giving an opinion on epidemiological features. Our study was a retrospective study consisted of 298 patients who had medical operations with the diagnosis of endometrial cancer. Endometrial cancer was diagnosed via dilatation and curettage. Routine preoperative examinations were wanted from the cases. Clinical stage was determined. After the diagnosis, total abdominal hysterectomy and bilateral salpingo-ooforectomy (TAH+BSO were applied; while only pelvic lymph node dissection was applied on the patients who had good prognostic data, total pelvic and paraaortic lymph node dissection were applied to the group with bad prognostic data. All materials were examined in the pathology laboratory of our hospital. In endometrial cancer staging, FIGO surgical staging system -2009 was used. FIGO was used in grade classification and World Health Organization Classification of Tumors system was used for the histological classification. Our study was composed of 298 patients who had endometrial cancer. Of the patients who were included in the study, average age was 56.54±9.69, BMI average was 31.47±6.20, gravida average was 4.16±2.59, and parity average was 3.41±2.15. Distributions of the patients by surgical stages were as follows; there were 32 patients whose tumor stage was in 1A (%10.7, 127 patients in 1B  (42.6%, 47 patients in 1C  (15.8%, 18 patients in 2A  (6.0%, 7 patients in 2B   (2.3%, 30 patients in 3A  (10.1%, 2 patients in 3B  (0.7%, 30 patients in 3C  (10.1%, 2 patients in 4A  (0.7% and 3 patients in 4B  (1.0%.

    Acute appendicitis is the most common non-obstetric surgery pathology in pregnancy, itsincidence can be varied and occurs at a higher rate during the first and second trimesterof gestation. Its diagnosis is difficult and can be confused by the anatomical andphysiological changes during pregnancy, which alter their clinical presentation. Commonsymptoms are abdominal located pain, vomiting and nausea. The diagnosis is mainlyclinical, but laboratory tests and additional imaging help confirm or r...

    To determine superior-inferior anatomic borders for CT following inconclusive/nondiagnostic US for possible appendicitis. Ninety-nine patients with possible appendicitis and inconclusive/nondiagnostic US followed by CT were included in this retrospective study. Two radiologists reviewed CT images and determined superior-inferior anatomic borders required to diagnose or exclude appendicitis and diagnose alternative causes. This ''targeted'' coverage was used to estimate potential reduction in anatomic coverage compared to standard abdominal/pelvic CT. The study group included 83 women and 16 men; mean age 32 (median, 29; range 18-73) years. Final diagnoses were: nonspecific abdominal pain 50/99 (51 %), appendicitis 26/99 (26 %), gynaecological 12/99 (12 %), gastrointestinal 9/99 (10 %), and musculoskeletal 2/99 (2 %). Median dose-length product for standard CT was 890.0 (range, 306.3 - 2493.9) mGy.cm. To confidently diagnose/exclude appendicitis or identify alternative diagnoses, maximum superior-inferior anatomic CT coverage was the superior border of L2-superior border of pubic symphysis, for both reviewers. Targeted CT would reduce anatomic coverage by 30-55 % (mean 39 %, median 40 %) compared to standard CT. When CT is performed for appendicitis following inconclusive/nondiagnostic US, targeted CT from the superior border of L2-superior border of pubic symphysis can be used resulting in significant reduction in exposure to ionizing radiation compared to standard CT.

    ABSTRACT Entamoeba histolytica is not a common causative agent of acute appendicitis. However, amoebic appendicitis can sometimes be severe and life threatening, mainly due to a lack of awareness. Also, its frequency, clinical features, and pathogenesis remain unclear. The study subjects were HIV-1-infected individuals who presented with acute appendicitis and later underwent appendectomy at our hospital between 1996 and 2014. Formalin-fixed paraffin-embedded preserved appendix specimens were reexamined by periodic acid-Schiff (PAS) staining and PCR to identify undiagnosed amoebic appendicitis. Appendectomies were performed in 57 patients with acute appendicitis. The seroprevalence of E. histolytica was 33% (14/43) from the available stored sera. Based on the medical records, only 3 cases were clinically diagnosed as amoebic appendicitis, including 2 diagnosed at the time of appendectomy and 1 case diagnosed by rereview of the appendix after the development of postoperative complications. Retrospective analyses using PAS staining and PCR identified 3 and 3 more cases, respectively. Thus, E. histolytica infection was confirmed in 9 cases (15.8%) in the present study. Apart from a significantly higher leukocyte count in E. histolytica-positive patients than in negative patients (median, 13,760 versus 10,385 cells/μl, respectively, P = 0.02), there were no other differences in the clinical features of the PCR-positive and -negative groups. In conclusion, E. histolytica infection was confirmed in 9 (15.8%) of the appendicitis cases. However, only 3, including one diagnosed after intestinal perforation, were diagnosed before the present analyses. These results strongly suggest there is frequently a failure to detect trophozoites in routine examination, resulting in an underestimation of the incidence of amoebic appendicitis. PMID:27847377

    Full Text Available CONTEXT Appendicitis is the one of the most common emergencies of the acute abdomen encountered by the clinicians; peritonitis is the common cause due to appendicular perforation. Ultrasonography of abdomen is the preferred method of diagnosis of acute appendicitis. The study is done to diagnose acute appendicitis in a tertiary care hospital to ascertain early diagnosis prevalent in this part of the country, which might differ from other studies. AIM To ascertain prevalence, presentation and management of appendicitis in this part of India in a tertiary care government hospital with provisional diagnosis of appendicitis. MATERIAL AND METHODS Cases of acute abdomen, clinical diagnosis of acute appendicitis admitted in KIMS Hospital, Hubli, a tertiary care government hospital, from January 2014 to January 2015 for materials of this study. 100 cases have been taken for study; cases included in this study are acute appendicitis, appendicular abscess; method used is USG abdomen, a simple diagnostic tool. RESULTS In present study, 100 cases of acute abdomen with clinical diagnosis of acute appendicitis were taken and laparotomy was done for 98 cases and two cases of appendicular abscess. Youngest patient was 7 years old and oldest was 65 years. Peak incidence between 11 to 30 years of age group and male to female ratio is 3:2. Postoperative wound infection was a common complication in 21 cases and retention of urine was noticed in 7 cases, and there was a death in one case due to septicaemia. CONCLUSION Acute appendicitis is a second most common indication for early laparotomy in KIMS Hospital, Hubli, first being perforative peritonitis. Acute appendicitis is common between 11 to 30 years of age group, early diagnosis and intervention is required to prevent appendicular perforation and its complications. Diagnosis of acute appendicitis is to be done in patients presenting with atypical pain, absence of vomiting does not rule out appendicitis. Anorexia

    Full Text Available Abstract Background Appendiceal parasites can cause symptoms of appendiceal pain, independent of microscopic evidence of acute inflammation. The diagnosis of a parasitic infestation is generally achieved only after the pathologic examination of the resected appendices. Patients/Methods Pathology department records were reviewed for all patients who required an operation for symptoms of acute appendicitis between 2000 and 2006. The specimens which were pathologically diagnosed to contain parasites were reevaluated for features of acute inflamation, and parasite type. The medical records were reviewed in detail to achieve a diagnostic score(Eskelinen. Radiologic imaging findings were correlated, if present. Results Of the 190 appendectomies performed, 6 specimens (3,15% were found to contain parasites(4 Enterobius vermicularis, 2 Taenia subspecies. Appendectomies with Taenia showed acute inflamation, while acute inflamation was absent in the ones with Enterobius vermicularis. The Eskelinen score was higher than the treshold in two cases with an acute inflamation, and in two without. Ultrasound scans, and a computed tomography scan were performed in 5 patients. In 3 of 4 bland appendices, results favored acute appendicitis. Conclusion The diagnosis of gastrointestinal parasites is not only made by examining the stool but the diagnosis can be made by histology from surgical specimens. Timely diagnosis and appropriate therapy might prevent probable future complications that may necessitate surgical procedures, at least in some of the patients. The clinical management of these infections is different from that for classical appendicitis.

    Acute appendicitis is one of the most common abdominal emergencies requiring surgery. It still represents, however, a challenging diagnosis. In order to facilitate this process, several scoring systems were developed, namely, the Alvarado score, acute inflammatory response and Raja Isteri Pengiran Anak Saleha Appendicitis scores, which are the most used in clinical practice. This clinical condition encompasses a wide spectrum of clinical presentations, from the uncomplicated form to the one with diffuse peritonitis. Treatment of uncomplicated acute appendicitis remains a matter of discussion. Although appen-dectomy has been regarded as the gold-standard, conservative management with antibi-otics is gaining more and more acceptance. The approach to appendectomy constitutes another controversial issue, namely, its performance through an open or a laparoscopic approach, which seems to be establishing itself, in some centers, as the standard of care. With this paper, we intend to give some insight on the aforementioned topics, through a review of the available literature on uncomplicated appendicitis.

    To decrease the negative appendectomy rate in children, knowledge of the misleading imaging findings on US and CT in negative appendicitis cases is important. To evaluate the negative appendectomy rate and describe the imaging findings of US and CT that lead radiologists to misdiagnose acute appendicitis in children. From 2007 to 2013, 374 children operated for suspected appendicitis were proved to either have acute appendicitis (n = 348) or to be negative for appendicitis (n = 26) on pathological reports. Negative appendectomy rates were compared among imaging modalities, age groups and genders. We retrospectively reviewed US and CT findings from negative appendectomy cases. The overall negative appendectomy rate was 7.0% (26/374). There were no statistically significant differences among the subgroups. The most common misleading presentations on US were sonographic tenderness (9/16, 56%) and non-compressibility (9/16, 56%). The most common misleading finding on CT were the presence of an appendicolith or hyperdense feces (5/12, 42%). Periappendiceal fat inflammation was observed in only one case of negative appendicitis on US and on CT. Radiologists can misdiagnose children with equivocal diameters of appendices as having acute appendicitis when sonographic tenderness or non-compressibility is present on US and when an appendicolith or hyperdense feces is noted on CT. The possibility of negative appendicitis should be borne in mind when periappendiceal fat inflammation is absent or minimal in indeterminate cases. (orig.)

    The purpose of this study is to evaluate the current performance of ultrasound in the diagnosis of acute appendicitis. Retrospectively, patients who presented to a single institution between 2011 and 2012 were included. Diagnostic accuracy was calculated, with surgery considered gold-standard. Our data demonstrates that US relative to surgery-confirmed appendicitis has a sensitivity and specificity of 48.4% and 97.9%, respectively. The diagnostic accuracy was further increased when there was a low pre-test probability, with a NPV of up to 96.6%. Ultrasound has a strong PPV in the diagnosis of acute appendicitis, and in equivocal cases, the NPV is reliable.

    Full Text Available Background: The early diagnosis of acute appendicitis before progression to gangrene or abscess formation is recognized as important to minimize morbidity from this common disease process. The aim of this study was to assess the value of different risk factors in the diagnosis of perforation. Methods: This descriptive-analytic and retrospective study was conducted to investigate epidemiological characteristics in patients with perforated and non-perforated appendicitis. A series of 1311 patients who were operated on for acute appendicitis between years 1380-1382 in Shahid Beheshti and Yahya-nejad hospitals were reviewed.. Data gathered included age at operation, gender, care sought prior to admission for appendectomy including antibiotic and analgesic therapy, time of presentation in the year, duration of symptoms, signs and symptoms at the time of admission, and the patient’s living area. Results: One hundred twenty one of 1311 patients (9% had perforated appendicitis and 1190 patients (91% had unperforated appendicitis. Presentation and referral in the first 6-month was associated with higher perforation rate. Patients from rural area showed a higher rate of perforations. The perforation rate was significantly higher in elderly patients (>65 year. When the duration of symptoms was more than 12 hours at presentation, the risk of perforation showed a five-fold increase. 30.7% of perforated cases had used antibiotic or sedative before referring to the hospital. Conclusion: Appendiceal perforation continues to be a complication in patients with acute appendicitis and increased in the frequency as the age of the patients increase and the duration of symptoms lengthen. We also found that the perforation rate is higher in patients from rural area and in whom present in the first 6-month of the year, a finding that was not reported so far.

    Full Text Available Introduction: the finding of the vermiform appendix within a crural hernia (Amyand's hernia is a rare entity whose incidence is not described in the literature. Objective: the aim of this study was to report our hospital's experience in this kind of pathology. Material and methods: between 1993 and 2004, 4,572 acute appendicitis and 372 incarcerated crural hernia cases have been operated on in our hospital. We studied 6 cases of incarcerated crural hernia with vermiform appendix inside. We analyzed in retrospect the following parameters: age, sex, personal history, clinical manifestations, preoperative diagnosis, surgical technique, mean hospital stay, and outcome. Results: all patients were women with a mean age of 78.8 years. Most frequent clinical manifestations included pain and a mass in the right inguinocrural region, of variable intensity and duration. No clinical, laboratory, or radiographic signs help in reaching a correct preoperative diagnosis. General anesthesia and a crural approach are used in most surgical operations. In all cases an appendectomy was performed via the hernia sac, thus proving the presence of acute appendicitis in four of them (66.67%. A prosthetic mesh was used in 3 cases, and one case of wound infection was found. In the other cases we sutured the hernia ring using prolene. Conclusion: the finding of the appendix in an incarcerated crural hernia is a rare entity in old women that is difficult to diagnose preoperatively. Treatment includes appendectomy and herniorraphy. The use of prosthetic mesh is controversial.Introducción: la presencia del apéndice vermiforme en el interior de un saco herniario crural (hernia de Amyand constituye una entidad poco frecuente y cuya incidencia no está descrita en la literatura.

    Objectives To identify and evaluate profiles of US and CT features associated with acute appendicitis. Methods Consecutive patients presenting with acute abdominal pain at the emergency department were invited to participate in this study. All patients underwent US and CT. Imaging features known to be associated with appendicitis, and an imaging diagnosis were prospectively recorded by two independent radiologists. A final diagnosis was assigned after 6 months. Associations between appendiceal imaging features and a final diagnosis of appendicitis were evaluated with logistic regression analysis. Results Appendicitis was assigned to 284 of 942 evaluated patients (30%). All evaluated features were associated with appendicitis. Imaging profiles were created after multivariable logistic regression analysis. Of 147 patients with a thickened appendix, local transducer tenderness and peri-appendiceal fat infiltration on US, 139 (95%) had appendicitis. On CT, 119 patients in whom the appendix was completely visualised, thickened, with peri-appendiceal fat infiltration and appendiceal enhancement, 114 had a final diagnosis of appendicitis (96%). When at least two of these essential features were present on US or CT, sensitivity was 92% (95% CI 89–96%) and 96% (95% CI 93–98%), respectively. Conclusion Most patients with appendicitis can be categorised within a few imaging profiles on US and CT. When two of the essential features are present the diagnosis of appendicitis can be made accurately. PMID:20119730

    Full Text Available Background/Aim: Duodenal injury is an uncommon finding, accounting for about about 3 - 5% of abdominal trauma, mainly resulting from both penetrating and blunt trauma, and is associated with significant mortality (6 - 25% and morbidity (30 - 60%. Patients and Methods : Retrospective analysis was performed in terms of presentation, management, morbidity and mortality on 14 patients of duodenal injuries out of a total of 172 patients of abdominal trauma attending Subharti Medical College. Results: Epigastric pain (100% along with vomiting (100% is the usual presentation of duodenal injuries in blunt abdominal trauma, especially to the upper abdomen. Computed tomography (CT was diagnostic in all cases. Isolated duodenal injury is a rare finding and the second part is mostly affected. Conclusion: Duodenal injury should always be suspected in blunt upper abdominal trauma, especially in those presenting with epigastric pain and vomiting. Investigation by CT and early surgical intervention in these patients are valuable tools to reduce the morbidity and mortality.

    In order to find out the predisposing factors of local complications after appendectomy in two general hospitals, 268 charts of patients with acute appendicitis confirmed by surgery were reviewed. There were 142 males and 126 females. All wounds were closed and prophylactic antibiotics were not used. Sixty patients (22 per cent) developed local complications; 49 (81.7 per cent) surgical wound infection and 11 (18.3 per cent) with intra-abdominal abscess. In the wound infection group 25 per cent had complicated acute appendicitis and only one per cent non-complicated acute appendicitis. The correlation between the preoperative period and wound sepsis showed, the longer period the higher incidence of wound infection, 1.7 per cent with less than 24 hr. 11 per cent with less than 72 hr. and 78.9 per cent with more than 96 hr.

    Full Text Available Appendicitis is the most common cause of acute abdomen in children; approximately one third of all cases present with appendiceal perforation at the time of surgery. Some of postoperative complications in this condition are abscesses. In unusual places such as the scrotum however, for an intraabdominal event to cause a scrotal abscess, fluid displacement requires the presence of a patent processus vaginalis. We report the case of a child with perforated appendix followed by a scrotum abscess owing to a permeable vaginal canal. The abscess was and the patient wes and treatment was performed based triple scheme antibiotics, evolving satisfactorily. Key words: appendicitis, postoperative complications, residual abscess, inguinal canal.

    To evaluate the ultrasound (US) findings that can help differentiate lymphoid hyperplasia in the appendix from acute appendicitis. A total of 1230 patients (below 20 years old) suspected of having appendicitis received an appendectomy between November, 1999, and March, 2008, with US findings in 27 patients with pathologically proven lymphoid hyperplasia of the appendix. Of 167 patients that received an appendectomy from January, 2007, to December, 2007, 52 patients with acute appendicitis were retrospectively reviewed as a control group. Retrospective review of US images was performed by two radiologists who were blinded to the pathologic results. The review was based on 12 ultrasonographic criteria derived from reports on the diagnostic findings of the appendicitis. Compared with acute appendicitis, lymphoid hyperplasia in appendix had a smaller diameter (7.14{+-}1.22 mm vs 9.37{+-}1.80 mm, p < 0.001) and less wall thickening(1.38{+-}0.36 mm vs 1.74 {+-} 0.56 mm, p =0.001). Periappendicular inflammation (p < 0.001), intraluminal air (p = 0.006), round shape in transverse scan (p = 0.002),increased blood flow on color Doppler US (p = 0.03) were also different. US is a useful modality to differentiate lymphoid hyperplasia in the appendix from acute appendicitis

    AIM: To document unusual findings in appendectomy specimens.METHODS: The clinicopathological data of 5262 pa-tients who underwent appendectomies for presumed acute appendicitis from January 2006 to October 2010 were reviewed retrospectively. Appendectomies per-formed as incidental procedures during some other operation were excluded. We focused on 54 patients who had unusual findings in their appendectomy specimens. We conducted a literature review via the PubMed and Google Scholar databases of English lan-guage studies published between 2000 and 2010 on unusual findings in appendectomy specimens.RESULTS: Unusual findings were determined in 54 (1%) cases by histopathology. Thirty were male and 24 were female with ages ranging from 15 to 84 years (median, 32.2 ± 15.1 years). Final pathology revealed 37 cases of enterobiasis, five cases of carcinoids, four mucinous cystadenomas, two eosinophilic infiltra-tions, two mucoceles, two tuberculosis, one goblet-cell carcinoid, and one neurogenic hyperplasia. While 52 patients underwent a standard appendectomy, two pa-tients who were diagnosed with tuberculous appendi-citis underwent a right hemicolectomy. All tumors were located at the distal part of the appendix with a mean diameter of 6.8 mm (range, 4-10 mm). All patients with tumors were alive and disease-free during a mean follow-up of 17.8 mo. A review of 1366 cases reported in the English literature is also discussed.CONCLUSION: Although unusual pathological findings are seldom seen during an appendectomy, all appen-dectomy specimens should be sent for routine histo-pathological examination.

    Full Text Available BACKGROUND: Lichenoid dermatose s refer to various, clinically different inflammatory dermatoses which share in common, various essential lichenoid histologic features. AIMS AND OBJECTIVE: In this study we have analysed the different clinicopathological aspects in lichenoid reactions, as prompt diagnosis of these lesions can greatly influence the morbidity associated with the disease. STUDY DESIGN: This was a 14 month retrospective analysis of cases presenting to the department of dermatology from June 2013 till July 2014. MATERIALS AND METHODS: All new patients diagnosed with lichenoid reaction clinically and histopathologically were included in the study. INCLUSION CRITERIA: All newly diagnosed cases of Lichenoid tissue reactions within the time period mentioned above . EXCLUSION CRITERI A: Patients whose adequate records were unavailable Statistical Analysis: The SPSS, version 13 software was used to statistically analyse the data. RESULTS: A total of 66 cases were diagnosed as lichenoid reactions, 51 were lichen planus and 15 had licheno id eruptions. Males (53% were more commonly affected than female s (47%, with lower limbs (69. 69% being the most common site of predilection. Oral lesions were seen among eleven patients. Histopathologically, the most consistent findings with lichenoid r eaction was the presence of a lymphocytic infiltrate followed by vacuolar degeneration of basal cell layer, hyperkeratosis, hypergranulosis, acanthosis, pigment incontinence and a band like infiltrate over the basal layer. CONCLUSION: In our study, Licheno id reactions were more common among adults from the 2 nd to 4 th decade and can show ed a male preponderance, with the most frequent archetype being lichen planus. Thus this study emphasises on the need of histological analysis in various clinically similar c ases of lichenoid dermatoses in order to arrive at a definitive diagnosis.

    Full Text Available OBJECTIVE: to retrospectively assess the results from cases treated in the hand surgery service, starting from a preestablished protocol; and to conduct a critical analysis on the results achieved, with separation of the cases into their respective subgroups.METHODS: twenty-three patients and a total of 40 fingers were evaluated between January 2004 and December 2011. We correlated the altered anatomical structures found in the cases that underwent the surgical procedure and its results, with regard to both conservative and surgical treatment, emphasizing the main indications.RESULTS: the results were analyzed using the Sierget method of the Mayo Clinic.CONCLUSION: we observed that the cases of camptodactyly of the little finger alone in the flex-ible form (>60◦ that underwent surgical treatment uniformly presented excellent results. In the rigid forms, our observations indicated that there were benefits comprising gains of extension and correction of the deformity. However, the range of motion with active flexion in the proximal interphalangeal joint was always partial. With evolution over time, some cases presented some loss of the gain previously achieved, which corroborates the need for continual vigilance during the follow-up, with systematic use of braces until the final phase of skeletal growth.

    The identification of Propionibacterium acnes in cultures of bone and joint samples is always difficult to interpret because of the ubiquity of this microorganism. The aim of this study was to propose a diagnostic strategy to distinguish infections from contaminations. This was a retrospective analysis of all patient charts of those patients with >or=1 deep samples culture-positive for P. acnes. Every criterion was tested for sensitivity, specificity, and positive likelihood ratio, and then the diagnostic probability of combinations of criteria was calculated. Among 65 patients, 52 (80%) were considered truly infected with P. acnes, a diagnosis based on a multidisciplinary process. The most valuable diagnostic criteria were: >or=2 positive deep samples, peri-operative findings (necrosis, hardware loosening, etc.), and >or=2 surgical procedures. However, no single criterion was sufficient to ascertain the diagnosis. The following combinations of criteria had a diagnostic probability of >90%: >or=2 positive cultures + 1 criterion among: peri-operative findings, local signs of infection, >or=2 previous operations, orthopaedic devices; 1 positive culture + 3 criteria among: peri-operative findings, local signs of infection, >or=2 previous surgical operations, orthopaedic devices, inflammatory syndrome. The diagnosis of P. acnes osteomyelitis was greatly improved by combining different criteria, allowing differentiation between infection and contamination.

    Emergent MRI is now a viable alternative to CT for evaluating appendicitis while avoiding the detrimental effects of ionizing radiation. However, primary employment of MRI in the setting of clinically suspected pediatric appendicitis has remained significantly underutilized. To describe our institution's development and the results of a fully implemented clinical program using MRI as the primary imaging evaluation for children with suspected appendicitis. A four-sequence MRI protocol consisting of coronal and axial single-shot turbo spin-echo (SS-TSE) T2, coronal spectral adiabatic inversion recovery (SPAIR), and axial SS-TSE T2 with fat saturation was performed on 208 children, ages 3 to 17 years, with clinically suspected appendicitis. No intravenous or oral contrast material was administered. No sedation was administered. Data collection includes two separate areas: time parameter analysis and MRI diagnostic results. Diagnostic accuracy of MRI for pediatric appendicitis indicated a sensitivity of 97.6% (CI: 87.1-99.9%), specificity 97.0% (CI: 93.2-99.0%), positive predictive value 88.9% (CI: 76.0-96.3%), and negative predictive value 99.4% (CI: 96.6-99.9%). Time parameter analysis indicated clinical feasibility, with time requested to first sequence obtained mean of 78.7 +/- 52.5 min, median 65 min; first-to-last sequence time stamp mean 14.2 +/- 8.8 min, median 12 min; last sequence to report mean 57.4 +/- 35.2 min, median 46 min. Mean age was 11.2 +/- 3.6 years old. Girls represented 57% of patients. MRI is an effective and efficient method of imaging children with clinically suspected appendicitis. Using an expedited four-sequence protocol, sensitivity and specificity are comparable to CT while avoiding the detrimental effects of ionizing radiation. (orig.)

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

    Objective To explore distinctive clinical manifestations and appropriate treatment, and assess prognosis of staphylococcal scalded skin syndrome ( SSSS). Methods A retrospective analysis was conducted of the data of 82 cases of SSSS hospitalized at Xinhua Hospital during the period from May 1993 to September 2003.Results The disease in all the 82 patients occurred in their first decade ( mean 2.5 years). Possible predisposing factors were found in 48 (58. 5% ). Fever was present in 78 (95. 1% ). Radial spokes of crusting around mouth were present in 80 (97. 6% ). Erythema began on the face, especially around the mouth and eye in 63 (76. 8% ).The course was acute in all cases and the eruptions quickly spread to the whole body within one day to two days. Of the 82 cases of SSSS, 47 were complete form of SSSS, 27 were abortive form of SSSS, and 8 were between the two forms. Staphylococcus aureus with positive staphylocoagulase was isolated from the possible primary infection sites including pharynx, eyelid, conjunctiva, nose, ear, and skin in 18 of 31 patients. Microbiological cultures of bullae and little pustulae developed after the onset were negative in 16 cases. All the 82 patients completely recovered after receiving antibiotic therapy ( ceftriaxone, oxacillin ) alone or in combination with human immunoglobulin (IVIG) therapy. Additional IVIG therapy was used in those patients who had systemic involvements such as pneumonia, fever higher than 38. 5℃ or leukocytosis. Conclusion SSSS is a spectrum disease. Besides abortive and complete forms, presenting between the two forms a new form might be appeared in 8 cases who developed both scarlatiniform rash and flaccid bullae. The abortive form and complete form are usually misdiagnosed clinically. Radial spokes of crusting around mouth seem to be characteristic manifestation of SSSS. All the patients in this study had favorable prognosis after receiving prompt diagnosis and appropriate treatment.

    2015-01-01

    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

    Objective:To assess the incidence, etiology, physiological and clinical features, mortality, and predictors of acute respiratory distress syndrome (ARDS) in intensive care unit (ICU).Methods: A retrospective analysis of 5 314 patients admitted to the ICU of our hospital from April 1994 to December 2003 was performed in this study. The ARDS patients were identified with the criteria of the American-European Consensus Conference ( AECC ). Acute physiology and chronic health evaluation Ⅲ ( APACHE in), multiple organ dysfunction syndrome score (MODS score), and lung injury score (LIS) were determined on the onset day of ARDS for all the patients. Other recorded variables included age, sex, biochemical indicators, blood gas analysis, length of stay in ICU, length of ventilation, presence or absence of tracheostomy, ventilation variables, elective operation or emergency operation.Results:Totally, 131 patients (2.5%) developed ARDS, among whom, 12 patients were excluded from this study because they died within 24 hours and other 4 patients were also excluded for their incomplete information. Therefore, there were only 115 cases (62 males and 53 females, aged 22-75 years, 58 years on average) left,accounting for 2. 2% of the total admitted patients. Their average ICU stay was (11. 27±7. 24) days and APACHE in score was 17.23±7.21. Pneumonia and sepsis were the main cause of ARDS. The non-survivors were obviously older and showed significant difference in the ICU length of stay and length of ventilation as compared with the survivors. On admission, the non-survivors had significantly higher MODS and lower BE ( base excess). The hospital mortality was 55. 7%. The main cause of death was multiple organ failure. Predictors of death at the onset of ARDS were advanced age, MODS≥8, and LIS≥2.76.Conclusions: ARDS is a frequent syndrome in this cohort. Sepsis and pneumonia are the most common risk factors. The main cause of death is multiple organ failure. The mortality is

    Astronauts perform exercise throughout their missions to counter the health declines that occur as a result of long-term exposure to weightlessness. Although all astronauts perform exercise during their missions, the specific prescriptions, and thus the mechanical loading, differs among individuals. For example, inflight ground reaction force data indicate that subject-specific differences exist in foot forces created when exercising on the second-generation treadmill (T2) [1]. The current exercise devices allow astronauts to complete prescriptions at higher intensities, resulting in greater benefits with increased efficiency. Although physiological outcomes have improved, the specific factors related to the increased benefits are unknown. In-flight exercise hardware collect data that allows for exploratory analyses to determine if specific performance factors relate to physiological outcomes. These analyses are vital for understanding which components of exercise are most critical for optimal human health and performance. The relationship between exercise performance variables and physiological changes during flight has yet to be fully investigated. Identifying the critical performance variables that relate to improved physiological outcomes is vital for creating current and future exercise prescriptions to optimize astronaut health. The specific aims of this project are: 1) To quantify the exercise-related mechanical loading experienced by crewmembers on T2 and ARED during their mission on ISS; 2) To explore relationships between exercise loading variables, bone, and muscle health changes during the mission; 3) To determine if specific mechanical loading variables are more critical than others in protecting physiology; 4) To develop methodology for operational use in monitoring accumulated training loads during crew exercise programs. This retrospective analysis, which is currently in progress, is being conducted using data from astronauts that have flown long

    Full Text Available Graded compressive sonography may be useful as an adjuvant in the diagnosis of acute appendicitis. To determine the role of sonography in the differential diagnosis of acute appendicitis, preappendectomy sonographic data of 164 consecutive cases in Fatemeh-Zahra Teaching Hospital were evaluated. Of 113 (68.9% patients who had acute appendicitis in histopathology, 64 (56.6% cases had preoperative sonographic diagnosis of acute appendicitis. Of 51 patients who had normal appendices, 40 (78.4% cases had normal appendices in sonographic evaluations. Sensitivity, specificity and accuracy of sonography for acute appendicitis were 56.7%, 78.4% and 0.63, respectively. The positive and negative predictive values were 85.3% and 44.49% respectively. As a result, sonographic evaluation is an additional diagnostic tool in acute appendicitis.

    Full Text Available Background: Surgical treatment of adult lumbar spinal disorders is associated with a substantial risk of intraoperative and perioperative complications. There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

  9. Abdominal CT Does Not Improve Outcome for Children with Suspected Acute Appendicitis

    Full Text Available Introduction: Acute appendicitis in children is a clinical diagnosis, which often requires preoperative confirmation with either ultrasound (US or computed tomography (CT studies. CTs expose children to radiation, which may increase the lifetime risk of developing malignancy. US in the pediatric population with appropriate clinical follow up and serial exam may be an effective diagnostic modality for many children without incurring the risk of radiation. The objective of the study was to compare the rate of appendiceal rupture and negative appendectomies between children with and without abdominal CTs; and to evaluate the same outcomes for children with and without USs to determine if there were any associations between imaging modalities and outcomes. Methods: We conducted a retrospective chart review including emergency department (ED and inpatient records from 1/1/2009–2/31/2010 and included patients with suspected acute appendicitis. Results: 1,493 children, aged less than one year to 20 years, were identified in the ED with suspected appendicitis. These patients presented with abdominal pain who had either a surgical consult or an abdominal imaging study to evaluate for appendicitis, or were transferred from an outside hospital or primary care physician office with the stated suspicion of acute appendicitis. Of these patients, 739 were sent home following evaluation in the ED and did not return within the subsequent two weeks and were therefore presumed not to have appendicitis. A total of 754 were admitted and form the study population, of which 20% received a CT, 53% US, and 8% received both. Of these 57%, 95% CI [53.5,60.5] had pathology-proven appendicitis. Appendicitis rates were similar for children with a CT (57%, 95% CI [49.6,64.4] compared to those without (57%, 95% CI [52.9,61.0]. Children with perforation were similar between those with a CT (18%, 95% CI [12.3,23.7] and those without (13%, 95% CI [10.3,15.7]. The proportion of

    We encountered multiple cases in which the US appearance of ruptured appendicitis mimicked intussusception, resulting in diagnostic and therapeutic delay and multiple additional imaging studies. To explore the clinical and imaging discriminatory features between the conditions. Initial US images in six children (age 16 months to 8 years; 4 boys, 2 girls) were reviewed independently and by consensus by three pediatric radiologists. These findings were compared and correlated with the original reports and subsequent US, fluoroscopic, and CT images and reports. All initial US studies demonstrated a multiple-ring-like appearance (target sign, most apparent on transverse views) with diagnostic consensus supportive of intussusception. In three cases, US findings were somewhat discrepant with clinical concerns. Subsequently, four of the six children had contrast enemas; two were thought to have partial or complete intussusception reduction. Three had a repeat US examination, with recognition of the correct diagnosis. None of the US examinations demonstrated definite intralesional lymph nodes or mesenteric fat, but central echogenicity caused by debris/appendicolith was misinterpreted as fat. All showed perilesional hyperechogenicity that, in retrospect, represented inflamed fat ''walling off'' of the perforated appendix. There were four CTs, all of which demonstrated a double-ring appearance that correlated with the US target appearance, with inner and outer rings representing the dilated appendix and walled-off appendiceal rupture, respectively. All six children had surgical confirmation of perforated appendicitis. Contained perforated appendicitis can produce US findings closely mimicking intussusception. Clinical correlation and careful multiplanar evaluation should allow for sonographic suspicion of perforated appendicitis, which can be confirmed on CT if necessary. (orig.)

    Endoscopic mucosal resection (EMR) allows the removal of flat or sessile lesions, laterally spreading tumors, and carcinoma of the colon or the rectum limited to the mucosa or the superficial submucosa. Acute appendicitis is the most common abdominal emergency requiring emergency surgery, and it is also a rare complication of diagnostic colonoscopy and therapeutic endoscopy, including EMR. In the case presented here, a 53-year-old female underwent colonoscopy due to a positive fecal occult blood test and was diagnosed with cecal adenoma. She was referred to our hospital and admitted for treatment. The patient had no other symptoms. EMR was performed, and 7 h after the surgery, the patient experienced right -lower abdominal pain. Laboratory tests performed the following day revealed a WBC count of 16000/mm(3), a neutrophil count of 14144/mm(3), and a C-reactive protein level of 2.20 mg/dL, indicating an inflammatory response. Computed tomography also revealed appendiceal wall thickening and swelling, so acute appendicitis following EMR was diagnosed. Antibiotics were initiated leading to total resolution of the symptoms, and the patient was discharged on the sixth post-operative day. Pathological analysis revealed a high-grade cecal tubular adenoma. Such acute appendicitis following EMR is extremely rare, and EMR of the cecum may be a rare cause of acute appendicitis.

    Xanthogranulomatous reaction can occur in any organ but the most common sites are kidney and gallbladder. Xanthogranulomatous appendicitis (XA) is a rare clinical entity. There are a few case reports of XA diagnosed on histopathology but none on cytology. Here we report a case of a 47-year-old lady who presented with acute abdomen and was found to have a mass lesion in the right iliac fossa. She was diagnosed with XA intraoperatively on imprint cytology that was subsequently confirmed on histopathological examination. Due to the rarity of XA itself and the use of imprint cytology for intraoperative diagnosis the case is being presented. PMID:28182060

    The aim of this study is to retrospectively evaluate the obstetric cases who referred to intensive care unit, and define the frequency, cause and clinic outcomes of the patients. Demographic data, causes of reference, interventions in the intensive care and the outcomes of 15 obstetric cases in the pregnancy and postpartum period, whose referred to Gaziosmanpasa University Hospital Intensive Care Unit between 2007 and 2013 were included and retrospectively evaluated. The frequency of patients who referred from another center to our intensive care unit was 10 (%66.6. The mean age of the patients was 28.80 +/- 5.74. The mean hospital stay time was 3.20 +/- 2.51. The most cause to refer into intensive care unit was postpartum hemorrhage. One of the cases was resulted in death. The mortality ratio was found as %6.7. In conclusion, the frequent cause of intensive care requirement of the obstetric cases were obstetric bleeding and uncontrolled hypertension. The maternal morbidity and mortality will be substantially decreased with advanced treatment modalities and maternal care before pregnancy. [J Contemp Med 2014; 4(1.000: 14-17

    Full Text Available Schistosomiasis is a water-borne trematode infestation and is one of the most widespread parasitic diseases in the world. Schistosomiasis can affect any organ, but is rare in the appendix. In this paper, the authors report a new case of appendicular schistosomiasis that was incidentally discovered in a 27-year-old male patient from Mali who underwent appendectomy for acute appendicitis. Appendectomy specimens removed from patients with appendicular schistosomiasis often appear macroscopically normal, but histopathological analysis of these cases confirms the diagnosis by revealing schistosomal eggs. The authors strongly recommend that all appendectomy specimens be examined histopathologically regardless of whether the specimens are macroscopically normal.

    The immune status was studied during the development of the disease in 182 children who were operated on for acute appendicitis. T lymphocytes and their subpopulations circulating in the blood, as well as B lymphocytes, immunoglobulins A, M, G, and immune complexes were determined. The character of changes of these values before the operation and in various postoperative periods were determined. The effect of complex treatment, including T-activin, on the clinical and immunological parameters in children with acute appendicitis was appraised. Analysis of the results showed that a transitory immunodepressive state forms in children with the disease, which is more marked in the destructive form, with normalization of the main values of cell-mediated and humoral immunity by the 7th day after appendectomy. In a complicated course of acute appendicitis the state of immunodeficiency is torpid in character and does not return to normal values even after clinical recovery, i.e. before discharge from the clinic. Inclusion of the immunostimulating agent T-activin into the complex treatment of patients with appendicitis ensures a more rapid involution of the main clinical manifestations of the disease. The therapeutic effect was most pronounced in destructive appendicitis: after 3 days of treatment the pain syndrome was encountered twice less frequently and intestinal paresis more than twice less frequently in these patients, and the term of hospital stay (8.8 +/- 0.4 days) was less shorter than for children of the control group (12.2 +/- 1.9 days) who did not receive T-activin in the therapeutic complex.

    Full Text Available To evaluate the clinical picture and outcome of suspected appendicitis in pregnant women. Retrospective analytic study of 28 appendectomies performed during pregnancy for suspected appendicitis in our hospital at period April 2004 to September 2006. All files and medical records of these patients were analyzed and studied. Those including variables (demographic, clinical, laboratory and surgical outcomes data were collected retrospectively. Prevalence of appendicitis was calculated from the total number of deliveries and abortions that occurred during this period. Numbers of correct and wrong diagnosis were reported and comparison of perinatal outcome, maternal morbidity and different variables in negative and positive laparotomies performed. The prevalence of suspected appendicitis in pregnancy is 0.29%. Incidences of negative laparotomies were 36%. The most diagnostic findings for acute appendicitis were history of periumbilical pain, anorexia and Rt iliac fossa findings. Half of wrong diagnosis were related to premature labor pain or abortion. The prevalence of suspected appendicitis during pregnancy in our environment during this period was higher than the reported incidence and rate of wrong diagnosis still high. Good clinical assessment with adjunct ultrasonic examination could reduce the incidence of negative laparotomies or prevent late complication. Delay in operation leading to higher rate of maternal morbidity and adversely affect the obstetric outcome.

    Nasolabial cysts are rare but easily identifiable when they do occur. They are thought to arise from the remnants of the nasolacrimal ducts, but most of the available information on these cysts is limited to isolated case reports. The purpose of our study was to examine the clinical and pathologic features of nasolabial cysts in order to provide a basis for their correct diagnosis and treatment. Eighteen patients with nasolabial cysts were treated at Korea University's Guro Hospital between Jan. 1, 1988, and Dec. 31, 1999. We retrospectively analyzed the clinical appearance, pathologic findings, and treatment results in each case. All patients underwent surgery via the sublabial approach. The lining epithelia were identified as either pseudostratified, stratified squamous, or simple cuboidal. A cyst recurred in only one case, and there were no surgical complications on follow-up. The results of our study provide a basis for sound diagnosis and treatment.

    We explored the relation between the causes of facial injuries in equestrians and the presence or absence of associated injuries. Over a 5-year period we retrospectively reviewed all patients who presented to the John Hunter Hospital, New South Wales, with facial injuries that had resulted from activity with horses. We analysed the rates of hard and soft tissue injuries, and of associated injuries by sex and mechanism. A total of 85 patients were included (50 female and 35 male) with an age range of 2-88 years. There was a significant difference in the rate of maxillofacial and associated injuries when groups were analysed for sex and mechanism of injury. Facial injuries caused by falling from a horse were more often associated with other injuries in men than in women (p<0.05), and men were 4 times more likely to present with associated injuries than women (OR 3.9; 95% CI 1.1 to 14) We also found significant differences in the rates of facial fracture. Women who had been kicked by a horse were more likely to sustain bony injuries than men (p<0.05). Our data confirm the association between kicks and facial fracture, and this may provide an impetus for the development of appropriate protective equipment. Patients who sustain facial injuries when falling from a horse often present with associated injuries and this has practical implications for clinicians involved in their management.

Methods: A retrospective designed study of 85 patients diagnosed with DNI such as peritonsillar, parapharyngeal, and submandibular abscesses. Results: A total of 85 patients were diagnosed with DNI. 33 of the 85 patients were younger than 18 (group of children, and 52 were older than 18 years of age (group of adults. The mean age of the patients was 24.109±14.003 (4-54 years. Trismus, fever, odynophagia and pain were the most common complaints in both groups. In the adults group, the peritonsillar space was the most common site of infection (49%. In children group, the parapharyngeal space was the most common site of infection (35%. All patients were given intravenous antibiotic therapy and additional drainage of the abscess was also carried out for some of the patients. Most frequently, intravenous ampicillin-sulbactam alone or in combination with metronidazole was administrated to the patients. Conclusion: Most of the cases of DNI can be treated with intravenous antibiotics in spite of the fact that if there is no clinical healing, drainage is needed.

    Objective: To review the evolution of the current surgical treatment for breast malignant tumors over the past twenty years in the First Hospital of Jilin University (the former Bethune University of Medical Sciences). Methods: 1195 eligible patients with primary breast malignant tumor diagnosed and surgically treated at the First Teaching Hospital from January 1980 and December 2000 were retrospectively analyzed. Results: The peak frequency was in 40-49 years of age (40.00%), the age of the patients with breast malignant tumors trends to become young. The most common pTNM classification was Stage Ⅱ. The most common histological type was infiltrating ductal carcinoma (398 patients, 33.31%), and simple carcinoma (279 patients, 23.53%). Modified radical mastectomy was the most common operation procedure performed (779 patients, 65.19%), and was increasingly used while radical mastectomy was adopted decreasingly in recent decade. Conclusion: The variation of operation procedures performed on patients with breast malignant tumors reflected the advance of our understanding of the biology of cancer and the progression of new treatment principles.

    1984-01-01

    The appropriateness of longitudinal analysis as a technique for studying migration is considered. Migration in Upper Volta (now Burkina Faso) is used as the example. Data are taken from the 1974-75 National Survey of Migration, in which 36,785 men and 38,987 women were questioned. The authors begin with a theoretical discussion of the biases to be expected in retrospective histories. They next look at the migration data using first longitudinal analysis and then cross-sectional analysis. Results, at least for this example, show that cross-sectional analysis of migration has the advantage over longitudinal analysis of allowing the correlations between changes in migration patterns and particular historical events to be seen more readily.

    In cases of partially uncharacteristic clinical symptoms with no typical leukocytosis and no ESR elevation, laparotomy reveals not seldom an acute phlegmonous appendix. As compared with the similar disease in younger people appendicitis of the aged presents more complications and a higher mortality rate which can partially explained by clinically meaningful secondary findings and a lesser degree of peritoneal inflammation. The mortality rate of appendicitis in the aged could be markedly reduced. This may be attributed to emergency operation of clinically diagnosed appendicitis in the aged, to improve anaesthetic technique, to infusion therapy and parenteral feeding and last not least postoperative administering of antibiotics.

    2017-01-01

    Renal infarction is a rare cause of referral to the emergency department, with very low estimated incidence (0.004%–0.007%). Usually, it manifests in patients aged 60–70 with risk factors for thromboembolism, mostly related to heart disease, atrial fibrillation in particular. We report a case of idiopathic segmental renal infarction in a 38-year-old patient, presenting with acute abdominal pain with no previous known history or risk factors for thromboembolic diseases. Because of its aspecific clinical presentation, this condition can mimic more frequent pathologies including pyelonephritis, nephrolithiasis, or as in our case appendicitis. Here we highlight the extremely ambiguous presentation of renal infarct and the importance for clinicians to be aware of this condition, particularly in patients without clear risk factors, as it usually has a good prognosis after appropriate anticoagulant therapy.

    2012-01-01

    Full Text Available Background: Tuberculosis (TB of hip constitutes nearly 15% of all cases of osteoarticular tuberculosis. We report a retrospective study carried out on 43 children with hip TB. Materials and Methods: Forty-three children of TB hip treated between 1971 and 2000 were analysed. Twenty-four children of the early series were treated with streptomycin (S, isoniazid (H and PAS (Pa for 18 months (3HPaS, 15 HPa, while 19 children in the later series were treated with isoniazid (H, rifampicin (R and ethambutol (E or pyrazinamide (Z for 12 months [(12 RHE(Z]. Five out of 18 children with radiologically normal appearing type hip TB were treated with chemotherapy alone and 38 children were subjected to surgery; simple synovectomy alone in 31 hips, joint debridement in six hips, and proximal femoral varisation osteotomy in one. After surgery hips were immobilized in cast for one to three months according to the severity of the disease and patients pain tolerance, and then were mobilized under leg traction in bed gradually till pain subsided completely. Results: TB of hip healed with minimum sequelae in all children. In 18 Type one hip TB, normal hip (synovial form anatomy was maintained, and in 25 patients with advanced lesions some defect in the femoral head and acetabulum was noticed, though painless good hip motion was maintained. Excellent to good results were obtained in 31 children (73.1%, fair in eight (18.6%, and poor in four (9.3%. In four patients with poor results, there was some residual morphological defect in the hip. None developed ankylosis of hip. Conclusion: We achieved good outcome with minimum sequelae in this series. The management goal should be aimed not only to heal the disease but also to maintain a painless mobile hip and anatomical cephalocotyloid relationship until maturity, and retard the development of secondary osteoarthritis.

    Natasha E C G Davies

    Full Text Available BACKGROUND AND METHODS: Little is known about antiretroviral therapy (ART outcomes in prisoners in Africa. We conducted a retrospective review of outcomes of a large cohort of prisoners referred to a public sector, urban HIV clinic. The review included baseline characteristics, sequential CD4 cell counts and viral load results, complications and co-morbidities, mortality and loss to follow-up up to 96 weeks on ART. FINDINGS: 148 inmates (133 male initiated on ART were included in the study. By week 96 on ART, 73% of all inmates enrolled in the study and 92% of those still accessing care had an undetectable viral load (<400 copies/ml. The median CD4 cell count increased from 122 cells/mm(3 at baseline to 356 cells/mm(3 by 96 weeks. By study end, 96 (65% inmates had ever received tuberculosis (TB therapy with 63 (43% receiving therapy during the study: 28% had a history of TB prior to ART initiation, 33% were on TB therapy at ART initiation and 22% developed TB whilst on ART. Nine (6% inmates died, 7 in the second year on ART. Loss to follow-up (LTF was common: 14 (9% patients were LTF whilst still incarcerated, 11 (7% were LTF post-release and 9 (6% whose movements could not be traced. 16 (11% inmates had inter-correctional facility transfers and 34 (23% were released of whom only 23 (68% returned to the ART clinic for ongoing follow-up. CONCLUSIONS: Inmates responded well to ART, despite a high frequency of TB/HIV co-infection. Attention should be directed towards ensuring eligible prisoners access ART programs promptly and that inter-facility transfers and release procedures facilitate continuity of care. Institutional TB control measures should remain a priority.

    Full Text Available BACKGROUND: Treatment of distal radius has undergone remarkable changes since the time of Abraham colles. Conservative treatment with cast application has given way to operative techniques for better o utcome in high demand young individuals. Volar plating fo r distal end radius fractures is an effective technique which allows early mobilisation with re storation of r adial inclination , radial length , articular congruity and palmar tilt. MATERIALS AND METHODS: T his study was performed in chettinad hospital and research institute between January 2013 and M arch 2014. 24 patients with closed isolated distal end radius fractures treated with open reduction and internal fixation with plates and screws by volar approach were followed up retrospectively for a minimum period of one year . There were 17 men and 7 women. Mean age was 44 years (Range, 22 - 75 years. The fractures were classified based on the AO system. There were 4 A2, 12 B3, 5 C1, 3 C2 fracture types. RESULTS : All the patients were evaluated with standard anteroposterior and lateral radiographs and CT scans in c ase of intraarticular fractures . In all patie nts plating of distal end radius done by volar approach. Patients were followed postoperatively for one y ear radiologically and clinically by modified clinical scoring system by Green and O Brien. Five patients had excellent results, thirteen patients had good results with twenty five percent restriction of wrist function . Five patients had fair results. One patient had postop wound infection which required implant removal and external fixator application . CONCLUSION: With proper patient selection a nd accurate surgical techniques , volar plating continues to be a useful method of treatment for distal end radius fractures with minimal complications and allowing early return of patients to normal activities.

    Marcos Lopes

    Full Text Available Abstract The Semantic Verbal Fluency (SVF test entails the generation of words from a given category within a pre-set time of 60 seconds. Objectives: To verify whether socio-demographic and clinical data of individuals with dementia correlate with the performance on the SVF test and to ascertain whether differences among the criteria of number of answers, clusters and data spread over the intervals, predict clinical results. Methods: This was a retrospective study of 49 charts of demented patients classified according to the Clinical Dementia Rating (CDR scale. We correlated education, age and gender, as well as CDR and Mini-Mental State Exam (MMSE scores with the number of answers, clustering and switching distributed over four 15-second intervals on the SVF test. Results: The correlation between number of answers and quartiles was weak (r=0.407, p=0.004; r=0.484, p<0.001 but correlation between the number of clusters and responses was strong (r=0.883, p<0.001. The number of items on the SVF was statistically significant with MMSE score (p=0.01 and there was a tendency for significance on the CDR (p=0.06. The results indicated little activity regarding what we propose to call cluster recalling in the two groups. Discussion: The SVF test, using number of items generated, was found to be more effective than classic screening tests in terms of speed and ease of application in patients with CDR 2 and 3.

    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.

    Full Text Available Aim: Osteosarcomas must be managed by a team which includes pathologists, radiologists, surgeons, radiation therapists, and medical oncologists. Treatment modalities and demographic charasteristics of osteosarcomas were analysed in this study. Material and Method: Primary osteosarcomas treated between 1999-2010 in Cukurova University Medical Faculty Department of Medical Oncology were analysed retrospectively. Results: Of the total 119 patients, 74% were male and 26% female. The median age was 19. The median follow up time was 37 months. The most frequently seen sarcomas were osteoblastic at 82.4%. Localization of the disease was found to be 55% in the lower extremity, 14.1% in the upper extremity, 13% in the head-neck, 6.6% in the thoracic area, and 4.1 % in the pelvic region. Some 6.41% were local stage, 25.64% locally advanced, 15.8% metastatic, and 14.10% were diagnosed with nuks disease. Chemotherapy was administered in 77 of 119 patients. Patients received different treatments: 23.1% were treated with preoperative chemotherapy, 16.67% postoperative, 9.52% palliative, 33.33% preoperative postoperative, 2.38% postoperative palliative, 9.52% preoperative postoperative palliative chemotherapy, and 4.76% of the patients did not receive chemotherapy. Both radical and conservative surgery was performed. The most common metastatic site was the lungs. The overall length of survival was 65 months (95%CI 30-59. The survival rates did not vary between the groups of preoperative, postoperative, preoperative postoperative chemotherapy and other groups (respectively 23 versus 36 versus 28 versus 44 months (p=0.8. No differences were evident for radiotherapy (p=0.06. Discussion: Osteosarcomas can be treated successfully with surgery, chemotherapy, and radiotherapy. There was no cumulative survival difference in results based on the types of chemotherapy used in this study. These results show the importance of a multimodality treatment approach including

    Full Text Available Spontaneous pneumothorax (SP is relatively common in clinical practice and occurs more frequently in young, tall thin men, and in smokers. However, simultaneous bilateral spontaneous pneumothorax (SBSP is a rare clinical condition that often presents with significant respiratory distress. It is often dangerous; therefore, the chest drain should be inserted immediately. In this study, simultaneus bilateral spontaneus pneumothoraces cases were divided into two groups and retrospectively evaluated according to age, sex, diagnostic methods, treatments, and results. Material and Methods :Between January 2006 and May 2009, 11 patients with SBSP were enrolled into our study. Age, gender, underlying lung disease, smoking history, symptoms, diagnosis, treatment type, surgical indication, morbidity, recurrence, mortality, duration of chest tube and postoperative hospital stay of the patients were reviewed. Arterial blood gas values (before and after intervention in patiens with primary and secondary spontaneous pneumothorax were evaluated. Results; 7 patients (63.63 % were male and 4 patients (36.37 % were female and their mean age was 34,5±6.81 years. There were 4 (36.37% primary SP and 4 (36.37% secondary SP patients. Chronic obstructive pulmonary disease (COPD was the most common cause in secondary SP patients. In two (18.18% patients recurrency were observed. Eight (72.72% patients had smoking history. The most common symptom in both groups was dyspnea. All patients had immediate bilateral chest tubes on admission. We treated these patients with chest drain insertion, VATS (Video-Assisted Thoracoscopic Surgery, axillary thoracotomy, and chemical pleurodesis. Postoperative morbidity was detected in 3 (27.27% patients (prolonged air leak in 1 case, empyema in 1 case and pneumonia in 1 case. No mortality was observed in alll cases. Recurrence developed in 3 (27.27% patients in this series. Conclusions: An urgent and effective treatment requires in the

    Full Text Available Acute appendicitis is more common in school-age children, but it rarely occurs in infants. The younger the patient, the fastest the course of the disease. In addition, there are greater risks of complications. A case of a nine-month-old infant, admitted to the pediatric hospital with fever and diarrhea, is presented. After several tests, he underwent surgery. Peritonitis caused by acute gangrenous appendicitis was diagnosed. While the patient was in the intensive care unit, he suffered a septic shock and acute multiple organ failure. As a result, he died 24 hours later. The biopsy confirmed the diagnosis of acute gangrenous appendicitis. Acute appendicitis is a disease that must be considered by doctors who treat infants with fever, diarrhea and abdominal pain related to irritability. Thus, an early diagnosis of the disease as well as the implementation of an appropriate surgical treatment can be performed.

    The authors present a case of enterobiasis of the appendix. Enterobius infection is an uncommon cause of acute appendicitis. Preoperative diagnosis of pinworm infestation is almost impossible unless there is a strong clinical suspicion. Parasites may produce symptoms which resemble acute appendicitis. Careful observation of the appendix stump may lead to intraoperative diagnosis of enterobiasis. A quick diagnosis and appropriate treatment may prevent future complications.

    2011-01-01

    Full Text Available The goal of this review is to present the state of the art in imaging tests for the diagnosis of acute appendicitis. Relevant publications regarding performance and advantages/disadvantages of imaging modalities for the diagnosis of appendicitis in different clinical situations were reviewed. Articles were extracted from a computerized database (MEDLINE with the following activated limits: Humans, English, core clinical journals, and published in the last five years. Reference lists of relevant studies were checked manually to identify additional, related articles. Ultrasound (US examination should be the first imaging test performed, particularly among the pediatric and young adult populations, who represent the main targets for appendicitis, as well as in pregnant patients. A positive US examination for appendicitis or an alternative diagnosis of possible gastrointestinal or urological origin, or a negative US, either showing a normal appendix or presenting low clinical suspicion of appendicitis, should lead to a final diagnosis. A negative or indeterminate examination with a strong clinical suspicion of appendicitis should be followed by a computed tomography (CT scan or alternatively, a magnetic resonanace imaging (MRI scan in a pregnant patient. A second US examination in a patient with persistent symptoms, especially if the first one was performed by a less experienced imaging professional, is a valid alternative to a CT.

    In recent years, skeletal age determination has become increasingly important in criminal investigations for determining the age of living individuals. To increase diagnostic accuracy, a physical examination, an X-ray examination of the left hand, as well as a dental examination including the determination of the dental status and an X-ray of the dentition should always be performed. In this work, the authors analyze a sample of 52 illegal immigrants who came under their observation in the period from May 1989 to September 2007. A statistical analysis of the results of dental and skeletal age estimations was performed as well as an analysis between the reported and assessed ages. The results showed a significant difference between reported age and assessed biological age (p<0.001); however, no statistical difference was shown between skeletal and assessed dental age (p=0.431).

    Much has been written regarding the incidence, types, importance and management of abdominal CT incidental findings in adults, but there is a paucity of literature on incidental findings in children. We sought to determine the prevalence and characteristics of extra-appendiceal and incidental findings in pediatric abdominal CT performed for suspected appendicitis. A retrospective review was performed of abdominal CT for suspected appendicitis in a pediatric emergency department from July 2010 to June 2012. Extra-appendiceal findings were recorded. Any subsequent imaging was noted. Extra-appendiceal findings were divided into incidental findings of doubtful clinical significance, alternative diagnostic findings potentially providing a diagnosis other than appendicitis explaining the symptoms, and incidental findings that were abnormalities requiring clinical correlation and sometimes requiring further evaluation but not likely related to the patient symptoms. One hundred sixty-five children had abdominal CT for suspected appendicitis. Seventy-seven extra-appendiceal findings were found in 57 (34.5%) patients. Most findings (64 of 77) were discovered in children who did not have appendicitis. Forty-one of these findings (53%) could potentially help explain the patient's symptoms, while 30 of the findings (39%) were abnormalities that were unlikely to be related to the symptoms but required clinical correlation and sometimes further work-up. Six of the findings (8%) had doubtful or no clinical significance. Extra-appendiceal findings are common in children who undergo abdominal CT in the setting of suspected appendicitis. A significant percentage of these patients have findings that help explain their symptoms. Knowledge of the types and prevalence of these findings may help radiologists in the planning and interpretation of CT examinations in this patient population. (orig.)

    The monsoon onset over Kerala is considered as the beginning of rain fall over India and it is the end of hot summer. Different criteria have been used to define the monsoon onset over Kerala, with the one given by India Meteorological Department taken as the standard criteria. The analysis of the past 20 years of observations shows that the variables during the monsoon onset do not behave in the same way always. The purpose of this paper is to analyses the monsoon onset phases and to find possible reasons behind the variable nature of the monsoon onset. Different meteorological parameters like precipitation, outgoing long wave radiation (OLR), winds, air temperature, and specific humidity at different levels are analyzed for the same. Research has been done on various distinct features of monsoon such as Low Level Jet (LLJ), Tropical Easterly Jet (TEJ), monsoon trough, and depressions etc., during the onset phase. The analysis showed that in some years the strength of LLJ is lesser compared to the normal years. It is also seen that in some years the wind flow pattern is different from that observed during a standard onset year. The results of these analyses will be presented in detail in the paper.

    Positive outcomes from intensive therapy for individuals with aphasia have been reported in the literature. Little is known about the characteristics of individuals who attend intensive comprehensive aphasia programs (ICAPs) and what factors may predict who makes clinically significant changes when attending such programs. Demographic data on participants from 6 ICAPs showed that individuals who attend these programs spanned the entire age range (from adolescence to late adulthood), but they generally tended to be middle-aged and predominantly male. Analysis of outcome data from 2 of these ICAPs found that age and gender were not significant predictors of improved outcome on measures of language ability or functional communication. However, time post onset was related to clinical improvement in functional communication as measured by the Communication Activities of Daily Living, second edition (CADL-2). In addition, for one sample, initial severity of aphasia was related to outcome on the Western Aphasia Battery-Revised, such that individuals with more severe aphasia tended to show greater recovery compared to those with mild aphasia. Initial severity of aphasia also was highly correlated with changes in CADL-2 scores. These results suggest that adults of all ages with aphasia in either the acute or chronic phase of recovery can continue to show positive improvements in language ability and functional communication with intensive treatment.

    Full Text Available Finding of increased numbers of eosinophils in the muscle in cases of acute appendicitis has led to the hypothesis that it may have an allergic origin. This study aimed to measure the eosinophil degranulation resulting in a rise in the serum of eosinophil granule proteins that would be expected in such cases. The levels of serum eosinophil cationic protein (ECP measured by chemiluminescence assay in acute appendicitis were compared, with those of appropriate controls. Mean (95% CI serum ECP (µg/L levels were: acute appendicitis 45.3 (27.7-63.0; normal appendix 22.7 (16.0-29.3; asthma 24.2 (4.6-43.8; and healthy volunteers 13.2 (8.3-18.1. In cases of acute appendicitis, there is an inverse relationship between duration of symptoms and serum ECP. However, this was not statistically significant. Significant local eosinophil activation and degranulation occurs in acute appendicitis, enough to cause a rise in serum levels of eosinophil chemotactic protein

    Full Text Available Background Low-dose computed tomography (LDCT techniques can reduce exposure to radiation. Several previous studies have shown that radiation dose reduction in LDCT does not decrease the diagnostic performance for appendicitis among attending radiologists. But, the LDCT diagnostic performance for acute appendicitis in radiology residents with variable training levels has not been well discussed. Objectives To compare inter-observer and intra-observer differences of diagnostic performance on non-enhanced LDCT (NE-LDCT and contrast-enhanced standard dose CT (CE-SDCT for acute appendicitis among attending and resident radiologists. Patients and Methods This retrospective study included 101 patients with suspected acute appendicitis who underwent NE-LDCT and CE-SDCT. The CT examinations were interpreted and recorded on a five-point scale independently by three attending radiologists and three residents with 4, 1 and 1 years of training. Diagnostic performance for acute appendicitis of all readers on both examinations was represented by area under receiver operating characteristic (ROC curves. Inter-observer and intra-observer AUC values were compared using Jackknife FROC software on both modalities. The diagnostic accuracy of each reader on NE-LDCT was compared with body mass index (BMI subgroups and noise using independent T test.

    No reliably specific marker for acute appendicitis has been identified. Although recent studies have shown hyperbilirubinaemia to be a useful predictor of appendiceal perforation, they did not focus on the value of bilirubin as a marker for acute appendicitis. The aim of this study was to determine the value of hyperbilirubinaemia as a marker for acute appendicitis.

  1. Funiculitis mimicking appendicitis: A rare culprit

    Full Text Available Acute appendicitis is an extremely common cause for pediatric admissions, most notably presenting with right lower quadrant pain. There are few other etiologies for a young male to have pain aside from appendicitis. We present a young boy who presented with right lower quadrant abdominal pain and fevers, but was found to have funiculitis. Funiculitis, or inflammation of the spermatic cord, is a very rare condition in the pediatric population, almost always occurring in the elderly with urinary flow conditions. We share our case to remind providers the importance of a full differential diagnosis.

  2. Recurrent epiploic appendagitis mimicking appendicitis and cholecystitis

    2017-01-01

    Epiploic appendagitis (EA) is a rare cause of acute abdominal pain caused by inflammation of an epiploic appendage. It has a nonspecific clinical presentation that may mimic other acute abdominal pathologies on physical exam, such as appendicitis, diverticulitis, or cholecystitis. However, EA is usually benign and self-limiting and can be treated conservatively. We present the case of a patient with two episodes of EA, the first mimicking acute appendicitis and the second mimicking acute cholecystitis. Although recurrence of EA is rare, it should be part of the differential diagnosis of acute, localized abdominal pain. A correct diagnosis of EA will prevent unnecessary hospitalization, antibiotic use, and surgical procedures. PMID:28127129

    We describe the case of a 68-year-old otherwise healthy male who presented to our emergency room with signs and symptoms of acute appendicitis. Exploratory surgery revealed a normal appendix. Further examination revealed an enlarged lymph node-like mass of tissue near the appendix, in the ileocecal mesentery. This mass was removed and was found to be inflamed heterotopic gastric tissue. Although reports of heterotopic gastric tissue in the literature are common, we believe that this case represents the first report of inflamed heterotopic gastric tissue simulating appendicitis.

    Describe the findings in the ultrasonography and computerized tomography (CT) of the omental infarction and epiploic appendicitis. The clinical and radiological findings of the patients diagnosed in our hospital with epiploic appendicitis or omental infarctions between August 1994 and March 2001 were assessed retrospectively. We found a high incidence (42 cases) of these two diseases: 30 patients with diagnosis of epiploic appendicitis and 12 with the diagnosis of omental infarction. Four patients were treated surgically, while the remaining 38 were conservatively, without posterior complications. The ultrasonography and CT images is characteristics. making it possible to make a diagnosis of epiploic appendicitis or omental infarction with certainty. It is not necessary to make a differential diagnosis between the two entities because their prognosis and treatment are similar. Their incidence is much more frequent than that previously published.

    Retrospective experience curves are a useful tool for understanding historic technology development, and can contribute to investment program analysis and future cost estimation efforts. This work documents our development of an analysis approach for deriving retrospective experience curves with a variable learning rate, and its application to develop an experience curve for compact fluorescent lamps for the global and North American markets over the years 1990-2007. Uncertainties and assumptions involved in interpreting data for our experience curve development are discussed, including the processing and transformation of empirical data, the selection of system boundaries, and the identification of historical changes in the learning rate over the course of 15 years. In the results that follow, we find that that the learning rate has changed at least once from 1990-2007. We also explore if, and to what degree, public deployment programs may have contributed to an increased technology learning rate in North America. We observe correlations between the changes in the learning rate and the initiation of new policies, abrupt technological advances, including improvements to ballast technology, and economic and political events such as trade tariffs and electricity prices. Finally, we discuss how the findings of this work (1) support the use of segmented experience curves for retrospective and prospective analysis and (2) may imply that investments in technological research and development have contributed to a change in market adoption and penetration.

    2010-10-01

    Full Text Available Acute appendicitis of amebic origin is considered a rare cause of acute appendicitis. We report a case of amebic appendicitis presenting with fever, severe pain in the right lower quadrant of the abdomen and rebound tenderness. Lab investigations revealed neutrophilic leukocytosis. The patient underwent appendectomy. Histopathological examination revealed numerous Entameba histolytica trophozoites in the mucosa of the appendix. Acute appendicitis of amebic origin does not appear frequently. Appendicular amebiasis can give the clinical features of acute appendicitis and should be treated accordingly.

    CT was performed in 104 patients with abdominal pain suspected appendicitis. CT showed positive finding (abnormal appendix, appendicolith, pericecal inflammatory change, fluid collection, LN swelling, abscess) and complication of appendicitis clearly. CT diagnosis showed high accuracy than clinical diagnosis. CT proved its usefulness especially only CT imaging showed the correct diagnosis. On the other hand, diverticulitis and terminal ileitis common diagnostic disease of appendicitis showed similar clinical appearance and CT image, caused to be difficult to diagnose correctly. In the cases showing similar image to appendicitis or atypical image, CT also proved its limit of the diagnosis on appendicitis. (author)

    Full Text Available Enterobiasis is undoubtedly one of the most common human helminths infections through the world, with an estimate of 1000 million cases worldwide. Although adult worms and their eggs are frequently found in inflamed appendices, but the role of the parasite in producing appendicitis in humans still remains controversial. Although acute appendicitis may occur at any age, but it is relatively rare at the extremes of age. A histopathological study of infested appendices with Enterobius vermicularis was performed in Khuzestan province, south western Iran, during 2001 to 2003. All 40 samples had surgically been removed during the emergency operations and histopathological process with (H&E staining has been performed for each. One of the main objects of this work was to collect more data about the possible role of this highly prevalent human round worm as a causative agent of appendicitis in humans, leading to different types of appendicitis in this part of the country. In this occasion over the slide examinations of the tissue sections, fewer cases than expected, with worm infested appendices were seen exclusively affected with this parasite.

  16. Acute appendicitis in pregnancy: literature review

    Full Text Available Introduction: suspected appendicitis is the most common indication for surgery in non-obstetric conditions during pregnancy and occurs in about one in 500 to one in 635 pregnancies per year. This occurs more often in the second trimester of pregnancy. Acute appendicitis is the most common general surgical problem encountered during pregnancy. Methods: a literature review on research of scientific articles, under the terms “acute appendicitis” and “pregnancy”, in PubMed, Lilacs/SciELO, Scopus, Cochrane Library and Uptodate databases. Results: the clinical manifestations of appendicitis are similar to non-pregnant women, however, without a classic presentation, which often occurs, diagnosis is difficult and must be supported by imaging. Discussion: clinical diagnosis should be strongly suspected in pregnant women with classic findings such as abdominal pain that migrates to the right lower quadrant. The main purpose of imaging is to reduce delays in surgical intervention due to diagnostic uncertainty. A secondary objective is to reduce, but not eliminate, the negative appendectomy rate. Differential diagnosis of suspected acute appendicitis usually includes pathologies considered in non-pregnant people. Conclusion: the imaging study of choice is ultrasound, MRI may be used when the former is not conclusive and, as a last resort, a CT scan can be performed. The treatment remains appendectomy by laparotomy, since the feasibility of video- assisted surgery in these cases remains controversial.

    2015-05-01

    Full Text Available Appendicitis is one of the most common surgical emergencies. The incidence of appendicitis and chances of complication in the form of perforation are dependent on both the patients and non - patient factors . There are various studies conducted to address this problem, but there are no studies conducted to look in to the incidence of appendicitis in east Godavari district of Andhra Pradesh. Our study was aimed to bridge thi s gap. METHOD S AND MATERIALS: this was a retrospective study, patient data from 2009 - 2014 was analyzed and the age, distance from hospital, educational and socioeconomic background of the patients was collected. The duration between first appearance of sy mptoms and hospitalization was recorded. The incidence of post - op complication was also recorded. RESULTS: T he incidence of perforation was 15% in our study population, most of the patients were from low socioeconomic group and having income less than 5000 /month. The middle age group between 30 - 40 years was commonly affected by the appendicitis. The time laps between appearance of symptoms and hospitalization was found to be a predominant factor in the perforation. Surgical site infection was most common co mplication in the patients treated. CONCLUSION: T he incidence of perforation is still high and the time laps between first appearance of symptoms and hospitalization is a major determinant of perforation or complication in the appendicitis.

    2012-10-01

    Full Text Available Abstract Background Pancreatic Stone Protein (PSP is a protein naturally produced mainly in the pancreas and the gut. There is evidence from experimental and clinical trials that blood PSP levels rise in the presence of inflammation or infection. However, it is not known whether PSP is superior to other established blood tests (e.g. White Blood Count, Neutrophils or C - reactive protein in predicting appendicitis in patients presenting with abdominal pain and a clinical suspicion of appendicitis at the emergency room. Methods/design The PSP Appendix Trial is a prospective, multi-center, cohort study to assess the value of PSP in the diagnostic workup of acute appendicitis. 245 patients will be prospectively recruited. Interim analysis will be performed once 123 patients are recruited. The primary endpoint of the study concerns the diagnostic accuracy of PSP in predicting acute appendicitis and therefore the evidence of appendicitis on the histopathological specimen after appendectomy. Discussion The PSP Appendix Trial is a prospective, multi-center, cohort study to assess the value of PSP in the diagnostic workup of acute appendicitis.

    Full Text Available We encountered a case of gallbladder volvulus in an 88-year-old thin female in which the initial presentation was more consistent with that of acute appendicitis. After complete work-up, including physical exam, lab work, and computed tomography, the definite diagnosis of gallbladder volvulus was not made until intraoperative visualization was obtained. Gallbladder volvulus is a rare but serious condition, which requires a high clinical suspicion so prompt surgical intervention can be undertaken.

  8. Appendicitis/diverticulitis: diagnostics and conservative treatment.

    Science.gov (United States)

    Kruis, Wolfgang; Morgenstern, Julia; Schanz, Stefan

    2013-01-01

    Appendicitis and diverticulitis are very common entities that show some similarities in diagnosis and course of disease. Both are widely believed to be simple clinical diagnoses, which is in contrast to scientific evidence. An accurate diagnosis has to describe not only the initial detection, but particularly the severity of the disease. It is based mainly on cross-sectional imaging by ultrasound (US) and computed tomography (CT). Appendectomy is the standard treatment for acute appendicitis and is mandatory in complicated cases. Antibiotic therapy is similarly effective in uncomplicated appendicitis, but long-term results are not sufficiently known. Treatment of diverticulitis is related to the disease status. Complications such as perforation and bleeding require intervention. Uncomplicated diverticulitis as graded by US or CT are subject to conservative management, in the form of outpatient or hospital care. It is an unresolved debate as to whether antibiotic treatment offers benefits. Mesalazine seems at least to improve pain. The real challenge is treatment of recurrent diverticulitis. Lifestyle measures such as nutritional habits and physical activity are found to influence diverticular disease. Besides immunosuppression, obesity is a significant risk factor for complicated diverticulitis. Whether any medication such as chronic antibiotics, probiotics or mesalazine offers benefits is unclear. The indication for sigmoid resection has changed; it is no longer given by the number of attacks, but rather by structural changes as depicted by cross-sectional imaging.

    The objectives of this work were to retrospectively describe the radiographic assessment of INBONE total ankle arthroplasty in 30 patients using validated linear and angular measurements and to correlate these findings with the final surgical outcome over a 2-year follow-up period. Thirty consecutive patients (21 females, nine males; mean age, 64.8 years) underwent INBONE total ankle arthroplasty during 2007-2011. After IRB approval, a retrospective pre- and post-operative radiographic analysis was performed using validated linear and angular measurements. The pre- and post-operative assessment included the tibial angle, talar angle, tibial slope, and coronal deformity. Post-operative measurements also included the talocalcaneal angle, joint space height, talar height, lateral tibial component angle, lateral talar component angle, and anteroposterior tibial component angle. The post-operative bone loss, subluxation, positioning, and subsidence were also assessed. Statistical analysis was performed using two-sample t test and Fisher's exact test. Out of 30 patients, 23 had a successful clinical outcome with intact prosthesis at a 2-year follow-up. The only variables with significant correlation (p < 0.05) to the post-surgical outcome were the lateral talar component angle (p = 0.002) and the mean difference between pre- and post-operative tibial slope (p = 0.001). The coronal deformity had significant mean difference between pre- and post-operative values (p < 0.001); however, it lacked a significant correlation to the final surgical outcome. None of the categorical variables had a significant correlation with post-surgical outcome. In our retrospective study, only the lateral talar component angle and the mean difference between the pre- and post-operative tibial slope had significant correlation with post-surgical outcome in INBONE ankle arthroplasty. These measurements may be helpful in radiographic assessment of the INBONE ankle arthroplasty. (orig.)

  10. Schistosomal appendicitis: Incidence in Japan and a case report

    Schistosomal appendicitis is very rare in developed countries like the USA, Europe, and Japan. The author reviewed 311 pathologic archival specimens of vermiform appendix over the past 10 years. One case of schistosomal appendicitis was recognized. Therefore, the incidence of this disease was 0.32% in all appendices surgically resected in our hospital. The patient was a 41-year-old woman presenting with lower abdominal pain. She was a sailor traveling to many countries including endemic areas. Physical examination, laboratory data, and imaging modalities suggested an acute appendicitis, and appendectomy was performed under the diagnosis of ordinary appendicitis. Histologically, numerous schistosomal eggs were present in the vasculatures throughout the appendiceal walls. Some of the eggs were calcified. Stromal foreign body reaction was also recognized. The appendicitis was phlegmonous consisting of severe infiltrations of neutrophils and eosinophils. Acute serositis was also noted. Examination of feces revealed numerous eggs of Schistosoma mansoni. Clinicians should be aware of schistosomal appendicitis.

    Unenhanced MRI has emerged as a useful tool for diagnosing pediatric acute appendicitis. The use of contrast-enhanced MRI for diagnosing pediatric appendicitis has not been documented. The purpose of this study is to examine the diagnostic performance of contrast-enhanced MRI for acute appendicitis and alternative entities in the pediatric population presenting with acute abdominal pain. A retrospective review was conducted of 364 consecutive pediatric patients undergoing contrast-enhanced MRI for the evaluation of possible appendicitis at a single institution between November 2012 and September 2013. There were 132 cases of pathologically confirmed appendicitis out of 364 pediatric patients (36.3%) included in the study. Overall sensitivity and specificity were 96.2% (95% CI [91.4-98.4%]) and 95.7% (95% CI [92.3-97.6%]), respectively. Positive predictive value and negative predictive value were 92.7% (95% CI [86.6-96.3%]) and 97.8% (95% CI [94.7-99.1%]), respectively. The appendix was visualized in 243 cases (66.8%). Imaging confirmed alternative diagnoses in 75 patients, including most commonly colitis, enteritis or terminal ileitis (n = 25, 6.9%), adnexal cysts (n = 25, 6.9%) and mesenteric adenitis (n = 7, 1.9%). Contrast-enhanced MRI is capable of accurately diagnosing acute appendicitis while detecting many alternative entities of abdominal pain, and it allows good visualization of the appendix. Further evaluation is needed to determine whether contrast-enhanced MRI provides an advantage over non-enhanced MRI for imaging evaluation of acute abdominal pain in the pediatric population.

    Young adult cancer survivors (YAs) are confronted with immense financial challenges in the wake of their treatment. Medical bills and loss of savings may cause YAs to forgo recommended medications or follow-up appointments. Young survivors with financial concerns also report depression, stress and anxiety. The Samfund is a national nonprofit organization that provides financial support to YAs post-treatment. To quantify the financial burden of cancer in YAs, a retrospective analysis was performed of data collected from Samfund grant applications of 334 YA cancer survivors. Grants were awarded between 2007 and 2013 and grant recipients were consented electronically in 2014 for retrospective data analysis. Recipients ranged from 19 to 39 years of age at the time of their grant applications. Descriptive statistics were calculated and compared to the Medical Expenditure Panel Survey (MEPS) and U.S. census data on age-matched peers. Financial indicators of YA cancer survivors are worse in many domains than those of age-matched controls. Furthermore, YA survivors in their 30s report more perilous prefunding financial situations than younger grant recipients. Cancer has a devastating and age-specific impact on the finances of YAs. Philanthropic grants from the cancer support community, in conjunction with healthcare policy reforms, have the potential to break the cycle of financial need and help YAs move forward with their lives after cancer treatment.

    Suicide is an important health hazard worldwide. We retrospectively analyzed the autopsy records of the Institute of Forensic Medicine between 2010 and 2012 to document the characteristics of fatalities resulting from hanging in Kuwait. Upon analysis of death scene investigation and autopsy reports together with the information gathered from the police, the cases of hanging fatalities of suicidal origin were selected. A retrospective study was carried out on 118 suicidal hanging cases autopsied at Forensic Medicine Center in Kuwait (from 2010 to 2012). Of these cases, 86 (73%) were males and 32 females (27%). There was an increasing trend of hanging among ages between 21 and 50 years (87.3%) and the third decade had the highest number of victims (about 43%) between all age groups. Local Kuwaiti nationals comprised a small proportion of cases (7 persons, 5.9%), while the others were foreigners working in Kuwait with an Indian precedence (54 persons, 54.8%), followed by other 12 different nationalities representing 39.3% of the cases. In conclusion, there was a decreasing trend of suicide by hanging in Kuwait from 44 cases in 2010 to 25 cases in 2012.

    Full Text Available Histopathology tissue archives can be an important source of specimens for retrospective studies, as these include samples covering a large number of diseases. In veterinary medicine, archives also contain samples from a large variety of species and may represent naturally-occurring models of human disease. The formalin-fixed, paraffin-embedded (FFPE tissues comprising these archives are rich resources for retrospective molecular biology studies and pilot studies for biomarkers, as evidenced by a number of recent publications highlighting FFPE tissues as a resource for analysis of specific diseases. However, DNA extracted from FFPE specimens are modified and fragmented, making utilization challenging. The current study examines the utility of FFPE tissue samples from a veterinary diagnostic laboratory archive in five year intervals from 1977 to 2013, with 2015 as a control year, to determine how standard processing and storage conditions has affected their utility for future studies. There was a significant difference in our ability to obtain large amplicons from samples from 2015 than from the remaining years, as well as an inverse correlation between the age of the samples and product size obtainable. However, usable DNA samples were obtained in at least some of the samples from all years tested, despite variable storage, fixation, and processing conditions. This study will help make veterinary diagnostic laboratory archives more useful in future studies of human and veterinary disease.

    To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998-2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

    It is estimated that 30-50% of patients suffering from deep vein thrombosis (DVT) could be diagnosed with congenital or acquired thrombophilia. Its diagnosis, however, rarely changes the clinical management, but is associated with significant costs and negative psychological and social aspects. The aim of this study was to perform a retrospective analysis of the causes and clinical consequences of diagnostics for thrombophilia. A retrospective review of the medical records of 5600 patients was performed, 62 of whom had, at the time, been diagnosed for thrombophilia because of a thromboembolic event. A review of the current literature on the validity of diagnostic tests for hypercoagulability in certain clinical conditions was also performed. The most common reason for thrombophilia testing was episodes of lower limb DVT (56%). The most frequently diagnosed abnormalities were the heterozygous form of the V Leiden gene (18%), protein S deficiency (11%), and the anti cardiolipin antibody IgG (11%). In 45% of the patients, laboratory results did not confirm the presence of any congenital thrombophilia. After receiving the results, 11% of the respondents completed oral anticoagulation therapy after 3 months, and 28% of patients qualified for indefinite use of oral anticoagulant therapy. In most of the cases examined, the diagnosis of thrombophilia did not significantly affect the treatment. A common aberration identified in patients with a history of thromboembolic incidents was the coexistence of risk factors for atherosclerosis.

  8. Appendicitis/diverticulitis: minimally invasive surgery.

    Mutter, D; Marescaux, J

    2013-01-01

    Complicated intra-abdominal infections such as acute appendicitis and complicated diverticulitis represent both diagnostic and therapeutic challenges. Both diseases, although different in many ways, are caused by the obstruction of a blind pouch leading to inflammation, abscesses, and perforation of surrounding tissues. For many decades, acute appendicitis was managed through a conventional surgical incision in the right iliac fossa. As for other diseases, there is a significant tendency to propose less invasive treatments. For many teams, laparoscopy, which leads to less postoperative pain, a shorter hospital stay, and a quicker recovery, represents the standard of care for appendectomy. For selected cases, a medical approach can be proposed with satisfactory outcomes. Additionally, the management of complicated diverticulitis is also quickly moving towards less invasive procedures than the deleterious '3-phase surgery', which is Hartmann's procedure, followed by reversal protected with a stoma, and finally stoma closure. Benefiting from the evolution of antimicrobial therapy and interventional radiology, many complicated cases classified as Hinchey stage I and Hinchey stage II complicated diverticulitis are now treated medically. CT images allow the identification of patients requiring radiological drainage of localized abscesses or collections over 5 cm in size. Patients with Hinchey stage III sigmoiditis may benefit from an initial laparoscopic exploration allowing, in some cases, a conservative nonresective approach that will prevent laparotomy and stoma. Major resection leading to temporary or definitive stoma is usually indicated for stage IV complications and is required only in exceptional cases. Although a surgical intervention can be the definitive treatment for complicated intra-abdominal infections, multidisciplinary management including radiology, medical treatment, and laparoscopic surgery may limit the severe consequences of an acute surgical

Results are presented for several new flame retardants, including hexabromocyclododecane (HBCD), which was recently listed under the Convention (2013). These results represent the first global-scale distributions in air for these compounds. The targeted compounds are shown to have unique global distributions in air, which highlights the challenges in understanding the sources and environmental fate of each chemical, and ultimately in their assessments as persistent organic pollutants. The study also demonstrates the feasibility of using the PUF disk passive air sampler to study these new flame retardants in air, many of which exist entirely in the particle-phase as demonstrated in this study using a KOA-based partitioning model.

    Accumulation of a pure transudate abdominal effusion in the absence of significant hypoalbuminaemia is uncommon in dogs and is due to pre-sinusoidal portal hypertension. Reported causes of pre-sinusoidal portal hypertension vary, but suggest a reasonable prognosis. A retrospective analysis of 17 dogs that presented to our institution with ascites due to pre-sinusoidal portal hypertension identified idiopathic hepatic fibrosis or canine chronic hepatitis as the underlying cause in the majority of cases. Twelve (70.5%) dogs were 4 years of age or younger at time of presentation. Total serum protein was higher in dogs with chronic hepatitis than it was in dogs without inflammatory disease. The prognosis was generally poor and no histological, imaging or biochemical parameters were useful as prognostic indicators. Dogs died or were euthanased due to severe clinical signs associated with the portal hypertension and/or perceived poor prognosis.

    Human reproduction is considered as the most inefficient event as ∼15–20% of human pregnancies end in miscarriage and in the product of miscarriages, chromosomal anomalies are a common occurrence. The aim of the present retrospective study was to assess the frequency of chromosomal aberrations in couples with recurrent miscarriages in the region of Punjab and to compare with worldwide frequencies. In this study, a total of 440 cases were referred between the period 1995– 2015. After lymphocyte culturing, giemsa–trypsin banding was done for each case to assess the chromosomal anomalies. The frequency of chromosomal aberrations among couples was found to be 3.41% in our study. Among these aberrations, balanced reciprocal translocations formed the largest group with 60% anomalies. We would conclude that clinicians should understandthe importance of chromosomal analysis in these couples and refer them for karyotyping after two miscarriages to rule out the possible genetic cause of recurrent miscarriages.

    This research is aimed at understanding the dynamics of collaborative multi-party discourse across multiple communication modalities. Before we can truly make sig-nificant strides in devising collaborative communication systems, there is a need to understand how typical users utilize com-putationally supported communications mechanisms such as email, instant mes-saging, video conferencing, chat rooms, etc., both singularly and in conjunction with traditional means of communication such as face-to-face meetings, telephone calls and postal mail. Attempting to un-derstand an individual’s communications profile with access to only a single modal-ity is challenging at best and often futile. Here, we discuss the development of RACE – Retrospective Analysis of Com-munications Events – a test-bed prototype to investigate issues relating to multi-modal multi-party discourse.

    The numerical method which is based on flux difference splitting, LU decomposition, and implicit high-resolution third-order Essentially Non-Oscillatory (ENO) scheme was constructed for the efficient computation of steady state solution to three-dimensional incompressible Navier-Stokes equations in general coordinates. The flowfields over underwater axisymmetric bodies, full-appended axisymmetric bodies and axisymetric bodies with a ring-wing duct were simulated. The method is proved to be capable of predicting the circumferential-mean velocity distribution at model scale to the accuracy of around 3% of measured values, and of predicting some details of flow features, for example, the wake harmonics.

    A case of acute appendicitis in a premature baby in whom diagnosis was suggested on plain films of the abdomen is presented. In this baby air in a hollow viscus suspected of being an enlarged appendix was the clue to diagnosis. The diagnostic dilemma of this rare and life-threatening condition in premature babies and newborns is underlined. The relevance of different imaging modalities and of different findings in this age group is discussed. Awareness of this rare condition and possible differential diagnosis in newborns and premature babies is stressed. (orig.)

    Full Text Available Context: Snake bites are the common cause of morbidity and mortality in tropical countries. Aims: To analyze the outcome of snake bite victims Settings and Design: Retrospective analysis of data from Intensive care unit, Department of Anesthesiology. Materials and Methods: All the patients admitted in the intensive care unit for snake bite management during the year May 2004 - April 2009 were retrospectively reviewed. The data included age, sex, month and time of incident, site of bite, dose of anti--snake venom, time of anti--snake venom, administration, duration of mechanical ventilation, complications and death of a victim. Statistical analysis used: Pearson′s correlation test, paired samples t-test. Results and Conclusions: 113 patients reported to the Accident and Emergency with history of snake bite. 26 patients were referred to other hospital, 17 patients were brought dead, and 70 patients were admitted to the intensive care unit. In 59 snake-bite victims, maximum data could be recovered. Krait was the most common type of snake bite reported. There was a male preponderance (69.4% with age ranging between 20 and 40 years (52.5%. The mean lag time (time elapsed between bite and first dose of anti--snake venom was 5.3 ± 1.4 h and the mean anti-snake venom dose was 12.3 ± 2.4 vials. There was a positive and significant correlation between lag time and total dose of anti--snake venom (correlation coefficient =0.956, P<0.0001. Overall 72.9% patients required mechanical ventilation with a mean duration of 56.2 ± 16.1 h. 10.2% patients sustained cardiac arrest, 8.7% patients developed ventilator associated pneumonia, 6.7% suffered mild anti-snake venom reaction, 6.7% had hypotension and 5.1% patients developed renal failure. The overall mortality was 5.1%.

    Purpose: Total body irradiation (TBI) is a standard treatment modality within the multidisciplinary approach for allogeneous stem cell or bone marrow transplantation. However, surviving patients are at risk for developing a variety of late sequelae. This analysis aimed to retrospectively characterize late effects after TBI in adults treated in a single center. Patients and Methods: Patients {>=} 18 years treated with fractionated TBI (4-12 Gy) between 1996 and 2008 were included in this study. Treatment data were collected retrospectively from the treating departments. Late effects were evaluated using the clinic charts and/or were obtained from the general practitioners using a standardized questionnaire. Analyses were performed by calculation of the cumulative incidences using the Kaplan-Meier method and the log rank test. Results: A total of 308 patients {>=} 18 years were treated including a TBI of whom 78 patients were excluded from further analysis due to death within less than 1 year after TBI. Patients suffered from leukemia in most cases. Late toxicity follow-up was available in 120 patients (mean age 46.1 years; range, 18-70 years) after a mean follow-up of 23 months (range, 12-96 months). The cumulative incidences (CI) at 3 years were 28% for pulmonary event, 8% for pulmonary toxicity, 25% for kidney toxicity, 8% for cataract, 17% for bone toxicity, and 10% for secondary malignancy. The CI of bone toxicity was higher in female than in male patients (p = 0.019). Conclusion: Late effects after TBI in the context of allogeneous stem cell or bone marrow transplantation can frequently be observed. Regular follow-up examinations are advised for the early registration and treatment of adverse effects. (orig.)

    A prospective nonrandomized study investigating the accuracy and utility of autologous leukocyte scanning in the diagnosis of apendicitis was performed. One hundred patients in whom the clinical diagnosis of appendicitis was uncertain underwent indium 111 oxyquinoline labelling of autologous leukocytes and underwent scanning 2 hours following reinjection. Of 32 patients with proved appendicitis, three scans revealed normal results (false-negative rate, 0.09). Of 68 patients without appendicitis, three scans had positive results (false-positive rate, 0.03; sensitivity, 0.91; specificity, 0.97; predictive value of positive scan, 0.94; predictive value of negative scan, 0.96; and overall accuracy, 0.95). Scan results altered clinical decisions in 19 patients. In 13 cases, the scan produced images consistent with diagnoses other than appendicitis, expediting appropriate management. Early-imaging111 In oxyquinoline autologous leukocyte scanning is a practical and highly accurate adjunct for diagnosing appendicitis.

    Macroamylasemia is a condition of persistent, elevated serum amylase activity with no apparent clinical symptoms of a pancreatic disorder. In Korea, however, no such case has been reported to date. We report a case of a 17-year-old female diagnosed with macroamylasemia and acute appendicitis. One day earlier, she developed epigastric and right lower quadrant abdominal pain. She was characterized by high level of serum amylase, but normal lipase. Amylase isoenzyme analysis demonstrated increased fraction of salivary type and follow-up amylase level was persistently increased. Immunofixation disclosed the macroamylase binding with an immunoglobulin, consisting of IgA and kappa chain. The patient was treated by appendectomy, and the abdominal pain subsided.

    Magnetic resonance imaging for the evaluation of appendicitis in children has rapidly increased recently. This change has been primarily driven by the desire to avoid CT radiation dose. This meta-analysis reviews the diagnostic performance of MRI for pediatric appendicitis and discusses current knowledge of cost-effectiveness. We used a conservative Haldane correction statistical method and found pooled diagnostic parameters including a sensitivity of 96.5% (95% confidence interval [CI]: 94.3-97.8%), specificity of 96.1% (95% CI: 93.5-97.7%), positive predictive value of 92.0% (95% CI: 89.3-94.0%) and negative predictive value of 98.3% (95% CI: 97.3-99.0%), based on 11 studies. Assessment of patient outcomes associated with MRI use at two institutions indicates that time to antibiotics was 4.7 h and 8.2 h, time to appendectomy was 9.1 h and 13.9 h, and negative appendectomy rate was 3.1% and 1.4%, respectively. Alternative diagnoses were present in ~20% of cases, most commonly adnexal cysts and enteritis/colitis. Regarding technique, half-acquisition single-shot fast spin-echo (SSFSE) pulse sequences are crucial. While gadolinium-enhanced T1-weighted pulse sequences might be helpful, any benefit beyond non-contrast MRI has not been confirmed. Balanced steady-state free precession (SSFP) sequences are generally noncontributory. Protocols do not need to exceed five sequences; four-sequence protocols are commonly utilized. Sedation generally is not indicated; patients younger than 5 years might be attempted based on the child's ability to cooperate. A comprehensive pediatric cost-effectiveness analysis that includes both direct and indirect costs is needed.

    Full Text Available Objective. The aim of this study was to identify the patient demographics, health issues, and type of acupuncture treatments who visited a traditional Korean medical hospital for acupuncture treatment. Methods. We retrospectively analysed the data using the electronic medical records (EMRs of patients treated with at least one treatment of acupuncture from 1 January 2010 to December 2012 in the Chung-Ju Korean hospital at Semyung University. Results. The total number of identified patients was 1189 inpatients and 10138 outpatients. The 50–59 age group received acupuncture treatment in the hospital the most, followed by the 40–49 age group. Among the patients undergoing acupuncture treatment because of a diagnosis of pain, 82.74% were outpatients and 72.85% were inpatients. Additionally, all patients with a spine condition received acupuncture treatment. The most common musculoskeletal conditions of patients at the traditional Korean medicine (TKM hospital were associated with spine conditions, such as low back pain and neck pain. Various treatments have been performed at the hospital in conjunction with acupuncture. The study results show a high prevalence of acupuncture treatment for diagnosed diseases. Conclusion. Our study suggests the need to investigate additional TKM hospitals to analyse characteristics of patients who received specific treatments. Analysis of the characteristics of patients treated with Korean acupuncture at the TKM hospital in this study will help future researchers who want to implement strong clinical evidence. However, we cannot completely discount all symptoms because of the retrospective nature of this study, and only one hospital was used, which limits the generalisation of our findings.

    2009-01-01

    In the Summer of 2009, NASA's Modern Era Retrospective-analysis for Research and Applications (MERRA) will have completed 28 years of global satellite data analyses. Here, we characterize the global water and energy budgets of MERRA, compared with available observations and the latest reanalyses. In this analysis, the climatology of the global average components are studied as well as the separate land and ocean averages. In addition, the time series of the global averages are evaluated. For example, the global difference of precipitation and evaporation generally shows the influence of water vapor observations on the system. Since the observing systems change in time, especially remotely sensed observations of water, significant temporal variations can occur across the 28 year record. These then are also closely connected to changes in the atmospheric energy and water budgets. The net imbalance of the energy budget at the surface can be large and different signs for different reanalyses. In MERRA, the imbalance of energy at the surface tends to improve with time being the smallest during the most recent and abundant satellite observations.

    AIM: To investigate the clinical value of ultrasonographic diagnosis of biliary atresia (BA), a retrospective analysis of the sonogram of 20 children with BA was undertaken.METHODS: Ultrasonography (US) was performed in 20 neonates and infants with BA, which was confirmed with cholangiography by operation or abdominoscopy. The presence of triangular cord, the size and echo of liver, the changes in empty stomach gallbladder and postprandial gallbladder were observed and recorded.RESULTS: The triangular cord could be observed at the porta hepatis (thickness: 0.3-0.6cm) in 10 cases. Smaller triangular cord (0.2-0.26cm) can be observed in 3 cases. The gallbladder was not observed in 2 cases, and 1 case showed a streak gallbladder without capsular space. The gallbladders of 15 cases were flat and small. The gallbladders of 2 cases were of normal size and appearance, however, there was no postprandial contraction. The livers of all cases showed hepatomegaly and hetreogeneous echogenicity. Statistical analysis was performed to compare the hepatomegaly and hetreogeneous echogenicity and the stage of hepatic fibrosis.CONCLUSION: The presence of the triangular cord at the porta hepatis is specific. However, it is not the only diagnostic criterion, since flat and small gallbladder and poor contraction are also of important diagnostic and differential diagnostic significance. The degree of hepatomegaly and hetreogeneous echogenicity is proportional with liver fibrosis, and able to indicate the duration of course and prognosis.

    Given international concerns about students' pursuit (or more correctly, non-pursuit) of courses and careers in science, technology, engineering and mathematics, this study is about achieving a better understanding of factors related to high school students' engagement in science. The study builds on previous secondary analyses of Programme for International Student Assessment (PISA) datasets for New Zealand and Australia. For the current study, we compared patterns of science engagement and science literacy for male and female students in Canada and Australia. The study's secondary analysis revealed that for all PISA measures included under the conceptual umbrella of engagement in science (i.e. interest, enjoyment, valuing, self-efficacy, self-concept and motivation), 15-year-old students in Australia lagged their Canadian counterparts to varying, albeit modest, degrees. Our retrospective analysis further shows, however, that gender equity in science engagement and science literacy is evident in both Canadian and Australian contexts. Additionally, and consistent with our previous findings for indigenous and non-indigenous students in New Zealand and Australia, we found that for male and female students in both countries, the factor most strongly associated with variations in engagement in science was the extent to which students participate in science activities outside of school. In contrast, and again for both Canadian and Australian students, the factors most strongly associated with science literacy were students' socioeconomic backgrounds, and the amount of formal time spent doing science. The implications of these results for science educators and researchers are discussed.

    Full Text Available Urinary tract infection (UTI is one of the commonest medical problems in children. It can distress the child and may cause kidney damage. Prompt diagnosis and effective treatment can prevent complications in the child. But treatment of UTI in children has now become a challenge due to the emergence of multidrug resistant bacteria. Aims & Objectives: To know the bacteriological profile and susceptibility pattern of urinary tract infections in children and to know the prevalence of multidrug resistant uropathogens. Materials & Methods: A retrospective analysis was done on all paediatric urine samples for a period of one year. A total of 1581 samples were included in the study. Antimicrobial susceptibility testing was done on samples showing significant growth by Kirby-Bauer disc diffusion method. Statistical analysis: Prevalence and pattern were analyzed using proportions and percentages. Results: E.coli was the most predominant organism (56% causing UTI in children followed by Klebsiella sp (17%. Fifty three percent of gram negative organisms isolated from children were found to be multidrug resistant. Majority of E. coli isolates were found to be highly resistant to Ampicillin (91% and Cotrimoxazole (82% and highly sensitive to Imipenem (99% and Amikacin (93%. Conclusion: Paediatric UTI was common in children less than 5 years of age. Gram negative bacteria (E. coli and Klebsiella sp were more common than gram positive bacteria. Our study revealed that multidrug resistance was higher in E.coli.

    Retrospective analysis of diversity and species composition of marine macroalgae of Hainan Island in the period 1933-1992 is presented in this paper. There are two extensive sample collection periods of benthic macroalgae: the early collection (EC) covers a period between the early 1930s and the 1980s before considerable urbanization and reef degradation took place and a late collection (LC) was performed in 1990/1992 during a phase of rapid urbanization. Analysis of data also including an earlier published inventory of green algae covering the same collection sites (Titlyanov et al. 2011a) revealed that the marine flora of the island comprises 426 taxa in total, with 59% red algae, 18% brown algae and 23% green algae. In total 59 species of red algae, 11 species of brown algae and 37 species of green algae sampled during the LC are new records for Hainan Island. Considerable floristic changes between EC and LC became evident. In the LC there were significantly more filamentous, tubular or fine blade-like, and often epiphytic, green and red algae with a high surface-to-volume ratio. Additionally a reduction of green, brown and red algal species with larger fleshy or foliose thalli and a low surface-to-volume ratio was observed. It is assumed that the changes reflect the degradation of the coral reef ecosystem around Hainan, which was damaged by human activities especially in the 1950s-1970s.

    This talk will review the status and progress of the NASA/Global Modeling and Assimilation Office (GMAO) atmospheric global reanalysis project called the Modern Era Retrospective-Analysis for Research and Applications (MERRA). An overview of NASA's emerging capabilities for assimilating a variety of other Earth Science observations of the land, ocean, and atmospheric constituents will also be presented. MERRA supports NASA Earth science by synthesizing the current suite of research satellite observations in a climate data context (covering the period 1979-present), and by providing the science and applications communities with of a broad range of weather and climate data with an emphasis on improved estimates of the hydrological cycle. MERRA is based on a major new version of the Goddard Earth Observing System Data Assimilation System (GEOS-5), that includes the Earth System Modeling Framework (ESMF)-based GEOS-5 atmospheric general circulation model and the new NOAA National Centers for Environmental Prediction (NCEP) unified grid-point statistical interpolation (GST) analysis scheme developed as a collaborative effort between NCEP and the GMAO. In addition to MERRA, the GMAO is developing new capabilities in aerosol and constituent assimilation, ocean, ocean biology, and land surface assimilation. This includes the development of an assimilation capability for tropospheric air quality monitoring and prediction, the development of a carbon-cycle modeling and assimilation system, and an ocean data assimilation system for use in coupled short-term climate forecasting.

    • On the basis of class B evidence and consensus, acute appendicitis in children can often be diagnosed clinically with only selective use of imaging. (13)(14)(15)(16) • On the basis of class B evidence and consensus, ultrasonography is the test of choice when acute appendicitis is suspected but is unclear based on history, physical examination, and laboratory results. (17)(18)(19) • On the basis of class B evidence and consensus, the use of computed tomography scan should be limited to cases of suspected complex appendicitis with abscess or when there is clinical suspicion for acute appendicitis but ultrasonography results are not helpful. (16) • On the basis of class C evidence and consensus, children with possible appendicitis ideally should be treated in medical centers that have skilled sonographic personnel. (21) • On the basis of class B evidence and consensus, simple appendicitis should be treated by appendectomy during normal operating hours. Preoperative treatment with intravenous antibiotics and fluids during the overnight hours halts disease progression and allows for the safest surgery with the benefit of a full and rested staff. (24)(25)(26) • On the basis of class B evidence and consensus, complex appendicitis with a well-defined abscess can be treated nonoperatively initially, with the option of an interval appendectomy after recovery from the acute infection.

    Background: The short term outcome of patients undergoing surgery for Moyamoya disease can be affected by various perioperative factors. However, due to lesser prevalence of this disease in our country, data relating the effect of perioperative factors on the overall neurological outcomes of these patients is lacking. Aims: To analyze the effect of perioperative factors on the duration of postoperative hospital stay in patients undergoing surgery for Moyamoya disease. Settings and Design: It is a retrospective study analyzing various perioperative factors influencing the overall outcome of patients undergoing surgery for Moyamoya disease at a tertiary care centre in North India.

    In the majority of surgical departments in Denmark, the postoperative treatment for acute perforated appendicitis comprises three days of intravenous antibiotics. Recently, it has been proposed that such antibiotic regimen should be replaced by orally administered antibiotics. The aim of this paper...... was to give an overview of studies on acute perforated appendicitis with postoperative oral antibiotics. Five studies were found in a database search covering the 1966-2009 period. There is no evidence to support a conversion of the postoperative antibiotic regimen from intravenous to oral administration...... in patients with acute perforated appendicitis....

    Fusobacterium necrophorum is a well-known cause of Lemierre's syndrome. Recent studies suggest a causative association between F. necrophorum and acute appendicitis. We present a case of a 15-year-old previously healthy girl who presented with acute non-perforated appendicitis, intra......-abdominal abscesses and thrombosis that led to omental necrosis. This resulted in a life-threatening septic shock with the need for prolonged intensive care. We suggest that F. necrophorum identified in pus from the abdomen caused this fulminant variation of appendicitis with findings similar to those seen...

    Suspected cases of acute appendicitis in pregnancy are considered surgical emergencies due to the potentially devastating outcomes for both mother and unborn child if the appendix perforates. Acute appendicitis is also the number one cause of non-traumatic acute abdomen in pregnancy, as well as the number one cause of fetal death. We present a case report with a typical presentation of suspected acute appendicitis in a pregnant woman. The work up and diagnostic tools available are discussed at length, as well as the finer points in treatment of this population.

    Massive ovarian edema is a benign clinical entity, the imaging findings of which can mimic an adnexal mass or ovarian torsion. In the setting of acute abdominal pain, identifying massive ovarian edema is a key in avoiding potential fertility-threatening surgery in young women. In addition, it is important to consider other contributing pathology when ovarian edema is secondary to another process. We present a case of a young woman presenting with subacute abdominal pain, whose initial workup revealed marked enlarged right ovary. Further imaging, diagnostic tests, and eventually diagnostic laparoscopy revealed that the ovarian enlargement was secondary to subacute appendicitis, rather than a primary adnexal process. We review the classic ultrasound and MRI imaging findings and pitfalls that relate to this diagnosis.

    Full Text Available INTRODUCTION Acute appendicitis in a femoral hernia is an uncommon condition that can be serious. Complications are more frequent if the diagnosis is delayed and surgery is not performed on time. CASE REPORT We present a 71-year-old man with a painful swollen mass. The patient presented with fatigue and loss of appetite, while body temperature was normal. The abdomen was not painful, and peristaltic was normal. All laboratory findings were normal. After anamnesis and physical examination, the presumed diagnosis was incarcerated femoral hernia and the patient was sent to the operating room. Intraoperative findings revealed an incarcerated femoral hernia within a phlegmonous inflammated appendix. Appendectomy and McVay hernioplastics were done. The postoperative course was without complications. CONCLUSION It is very important to bear in mind that right femoral hernia with signs of incarceration and inflammation may contain an acutely inflamed appendix. Delayed diagnosis and misdiagnosis cause greater morbidity and mortality.

    Volumetric-modulated arc therapy (VMAT) is now widely used clinically, as it is capable of delivering a highly conformal dose distribution in a short time interval. We retrospectively analyzed patient-specific quality assurance (QA) of VMAT and examined the relationships between the planning parameters and the QA results. A total of 118 clinical VMAT cases underwent pretreatment QA. All plans had 3-dimensional diode array measurements, and 69 also had ion chamber measurements. Dose distribution and isocenter point dose were evaluated by comparing the measurements and the treatment planning system (TPS) calculations. In addition, the relationship between QA results and several planning parameters, such as dose level, control points (CPs), monitor units (MUs), average field width, and average leaf travel, were also analyzed. For delivered dose distribution, a gamma analysis passing rate greater than 90% was obtained for all plans and greater than 95% for 100 of 118 plans with the 3%/3-mm criteria. The difference (mean ± standard deviation) between the point doses measured by the ion chamber and those calculated by TPS was 0.9% ± 2.0% for all plans. For all cancer sites, nasopharyngeal carcinoma and gastric cancer have the lowest and highest average passing rates, respectively. From multivariate linear regression analysis, the dose level (p = 0.001) and the average leaf travel (p < 0.001) showed negative correlations with the passing rate, and the average field width (p = 0.003) showed a positive correlation with the passing rate, all indicating a correlation between the passing rate and the plan complexity. No statistically significant correlation was found between MU or CP and the passing rate. Analysis of the results of dosimetric pretreatment measurements as a function of VMAT plan parameters can provide important information to guide the plan parameter setting and optimization in TPS.

    Full Text Available Introduction: Phyllodes tumors (PT of the breast seem to get pre-operatively misdiagnosed as fibroadenomas resulting in inadequate resections and high local recurrence rates. Materials and Methods: Data of 150 patients with PT of the breast managed from January, 2003 to February, 2013 were retrospectively analyzed. Statistical analysis performed using SPSS version 17 (Pearson Chi-square test and analysis of variance test for analysis. Aim: The aim of this study is to compare clinico-pathological profile and recurrence rates in patients with benign (B, borderline malignant (BL and malignant (M PT. Results: In a total of 150 patients with PT (n = 77 B, n = 24 BL, n = 49 M, mean age was 36.92, 44.04 and 40.46 years respectively (P 0.015 and mean tumor size being 8.15 cm, 14.7 cm and 12.9 cm respectively (P 0.000. Pre-operatively cytology suggestive of PT in 24% patients with B PT and 63% in M PT; core tissue biopsy suggestive of PT in 85.4% patients with B PT and 100% in M PT. Recurrence seen in 34.7% out of which 32.7% were post-lumpectomy performed elsewhere. Majority of B PT had lumpectomy (49.3%/wide local excision (WLE, 31.2% compared with M PT where 55.1% had simple mastectomy (SM due to large tumor size. Local recurrence was more in M PT (53% compared with B PT (20%. We found recurrence rates in L (39.3% compared with WLE (27.3% and SM (33.9% (P 0.049. Conclusions: Larger tumor size, incomplete resection and M/BL histology predicted higher recurrence in PT. Core biopsy is much more accurate than fine needle cytology in the diagnosis.

    AIM: To analyze the operative and perioperative factors associated with hepatectomy of benign hepatic lesions.METHODS: A total of 827 condecutive cases of benign hepatic lesion undergoing hepatectomy from January 1986 to December 2005 in the Chinese PLA General Hospital were investigated retrospectively according to their medical documentation.RESULTS: The effect of operative and perioperative factors on the outcome of patients were analyzed. Of the 827 cases undergoing hepatectomy for more than 3 liver segments accounted for 22.1%, 316 (38.21%) required transfusion of blood products during operation. The average operating time was 220.59 ± 109.13 min, the average hospital stay after operation was 13.55 ± 9.38 d. Child-Pugh A accounted for 98.13%. The postoperative complication rate was 13.54% and the in-hospital mortality rate was 0.24%. Multivariate analysis showed that operating time (P = 0.004, OR = 1.003) and albumin value (P = 0.040, OR = 0.938) were the independent predictors of morbidity and indicated that operating time, blood transfusion, complication rate, and LOS had a trend to decrease.CONCLUSION: Hepatectomy for benign hepatic lesions can be performed safely with a low morbidity and mortality, provided that it is carried out with optimized perioperative management and an innovative surgical technique.

    A retrospective analysis of changes in costochondral rib grafts used to construct the condyle-ramus in children with hemifacial microsomia (HFM) was made. The mean age at surgical correction was 6.5 years, and the average follow-up was 4.5 years. Direct measurements were made on panoramic radiographs. The condyle-ramus length was expressed as a percentage change comparing the constructed with the normal side. During the first 2 postoperative years, there was either no change or a slight decrease in the length of the rib graft. After 2 years, however, the costochondral graft elongated at a slow, irregular rate. The mode change was 11 percent over the postoperative study period. In four patients who exhibited rapid growth of the normal condyleramus (greater than the mean change of 0.94 cm), the constructed side failed to keep pace. In another group of four patients who exhibited moderate elongation of the normal side, the grafted side grew commensurately or demonstrated greater than normal percentage change in length. There was no correlation between the initial size of the costochondral graft, age at time of operation, or presenting type of mandibular deformity. These findings are discussed in terms of the intrinsic growth and the functional matrix theories of mandibular development.

    Disruption of natural flow regimes, nutrient pollution, and other consequences of human population growth and development have impacted most major rivers of the world. Alarming losses of aquatic biodiversity coincide with human-caused river alteration, but effects of biotic homogenization on aquatic ecosystem processes are not as well documented. This is because unaltered systems for comparison are scarce, and some ecosystem-wide effects may take decades to manifest. We evaluated aquatic ecosystem responses to extensive river- floodplain engineering and nutrient addition in the Rio Grande of southwestern North America as revealed by changes in trophic structure of, and resource availability to, the fish community. Stable Isotope Analysis (SIA) was conducted on museum-preserved fishes collected over a 70-year period of intensive river management and exponential human population growth. Trophic complexity and resource heterogeneity for fish consumers (measured as "isotopic niche breadth") decreased following sediment deprivation and channelization, and these effects persist into the present. Increased nutrient inputs led to δ15N enrichment in the entire fish community at all affected sites, and a shift to autochthonous sources of carbon at the most proximal site downstream of wastewater release, probably via bottom-up transfer. Overall, retrospective SIA of apex consumers suggests radical change and functional impairment of a floodplain river ecosystem already marked by significant biodiversity loss.

    A three-year retrospective analysis of fungi isolated from specimens of patients with superficial fungal infections in French Guiana is presented. Clinical samples from 726 patients with presumptive diagnoses of onychomycosis (28.2% of the patients), tinea capitis (27.8%), superficial cutaneous mycoses of the feet (22.0%), and of other areas of the body (21.9%), were assessed by microscopic examination and culture. Dermatophytes accounted for 59.2% of the isolates, followed by yeasts (27.5%) and non-dermatophytic molds (13.1%). Trichophyton rubrum was the most common dermatophyte recovered from cases of onychomycosis (67.4%), tinea pedis (70.6%) and tinea corporis (52.4%). In contrast, Trichophyton tonsurans was the predominant species associated with tinea capitis (73.9%). Yeasts were identified as the principal etiologic agents of onychomycosis of the fingernails (74.2%), whereas molds were found mainly in cases of onychomycosis of the toenails. In such instances, Neoscytalidium dimidiatum (70.8%) was the most common mold recovered in culture. In conclusion, the prevalence of T. rubrum and the occurrence of onychomycosis and fungal infections of the feet in French Guiana are similar to results reported from Europe, whereas the frequency of tinea capitis and the importance of T. tonsurans in such infections are similar to the situation in the Americas.

    Full Text Available 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 (P=0.044 and P=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.

    1985-12-01

    Mahatma Gandhi's views on relating the world of formal education to the world of work were developed first in his experimental `Tolstoy Farm' in South Africa. On his return to India, Gandhi insisted that a required manual labour component in the curriculum would help regenerate India's village economy, develop in India's children a deeper understanding of India's cultural roots, motivate children to relate `book learning' to life in society, and destroy invidious caste distinctions. The major proposals and suggestions in Gandhi's writing will be discussed in the context of his hopes for using schooling as an agent of progress in India. Mao Ze-Dong's views, on the other hand, were developed in the context of his Yenan experience in the 1930s, i.e. the decision to consolidate a power base in the interior of China before waging a class war against the landlords and capitalists of China. Mao's views were also, to some extent, rooted in the Chinese reality of stagnant, poverty-stricken rural areas. But, Mao's writings indicate that Marxist hopes to relate theory and practice (as understood in dialectical materialism) and to ensure that everyone participated in mental as well as manual labour in a socialist society had led him to formulate his proposals. Both Gandhi's and Mao's views and proposals have been more or less abandoned in India and China respectively. The similar and dissimilar reasons which led to such a fate are examined in this retrospective analysis.

    Full Text Available Background/Aims: Airway difficulties leading to cardiac arrest are frequently encountered during propofol sedation in patients undergoing gastrointestinal (GI endoscopy. With a noticeable increase in the use of propofol for endoscopic sedation, we decided to examine the incidence and outcome of cardiac arrests in patients undergoing gastrointestinal (GI endoscopy with sedation. Patients and Methods: In this retrospective study, cardiac arrest data obtained from the clinical quality improvement and local registry over 5 years was analyzed. The information of patients who sustained cardiac arrest attributable to sedation was studied in detail. Analysis included comparison of cardiac arrests due to all causes until discharge (or death versus the cardiac arrests and death occurring during the procedure and in the recovery area. Results: The incidence of cardiac arrest and death (all causes, until discharge was 6.07 and 4.28 per 10,000 in patients sedated with propofol, compared with non–propofol-based sedation (0.67 and 0.44. The incidence of cardiac arrest during and immediately after the procedure (recovery area for all endoscopies was 3.92 per 10,000; of which, 72% were airway management related. About 90.0% of all peri-procedural cardiac arrests occurred in patients who received propofol. Conclusions: The incidence of cardiac arrest and death is about 10 times higher in patients receiving propofol-based sedation compared with those receiving midazolam–fentanyl sedation. More than two thirds of these events occur during EGD and ERCP.

    Full Text Available Purpose: To evaluate the efficacy, safety, predictability and stability of implanting a polymethylmethacrylate phakic intraocular lens (PIOL in high myopia. Materials and Methods: A retrospective analysis of the data of patients who underwent Artisan phakic IOL implantation between 2002 and 2003 with a follow-up of at least 24 months. Results: An Artisan myopia lens was implanted in 60 eyes of 36 patients with preoperative myopia ranging from -5.0 to -24.0 D. Mean patient age was 22.6 years. Mean spherical equivalent of manifest refraction stabilized by the first postoperative week. At three months follow-up, 54 eyes (90% had a postoperative refraction within ± 1D emmetropia and 45 eyes (75% had uncorrected visual acuity of 20/40 or better. Seven eyes (11.6% had loss of one Snellen line and none had loss of two Snellen lines or more at three months. The mean endothelial cell loss was 3.8% at three months, 5.2% at six months, 5.25% at 12 months and 6.38% at two years, which was not significant. Postoperative complications included anterior chamber reaction in two eyes (3.3%, rise in intraocular pressure in six eyes (10% and dislocation of PIOL in two eyes (3.3%. Conclusion: Implantation of Artisan myopia lens to correct high myopia resulted in a stable and fairly predictable refractive outcome with few complications. Significant endothelial damage was not detected in two years of follow-up.

In a retrospective analysis conducted in 2 Breton institutions we wanted to asses the frequency of this association and the outcome of these patients in a case-control study where each case (cirrhosis and esophageal cancer was paired with two controls (esophageal cancer. Results. In a 10-year period, we have treated 958 esophageal cancer patients; 26 (2.7% had a cirrhosis. The same treatments were proposed to the 2 groups; cases received nonsignificantly different radiation and chemotherapy dose than controls. Severe toxicities and deaths were more frequent among the cases. At the end of the treatment 58% of the cases and 67% of the controls were in complete remission; median and 2-year survival were not different between the 2 groups. All 4 Child-Pugh B class patients experienced severe side effects and 2 died during the treatment. Conclusions. This association is surprisingly infrequent in our population! Child-Pugh B patients had a dismal prognosis and a bad tolerance to radiochemotherapy; Child-Pugh A patients have the same tolerance and the same prognosis as controls and the evidence of a well-compensated cirrhosis has not modified our medical options.

    Performance assessment of personnel is an important component of an organization's quality management program, benefiting the organization, individuals and clients. Performance appraisal is the most common method. This article describes the three-part performance appraisal tool used at the authors' organization, a private inter-professional healthcare agency providing rehabilitation services to clients in the community, and presents the results of a retrospective analysis of the outcomes. Performance appraisals of 13 personnel were randomly selected, representing 39 chart audits and 25 joint client visits. The achievement of mandatory chart audit standards demonstrated 95 ± 7.2% compliance; expected standards showed 96 ± 3.3% compliance. Qualitative findings from the joint visits and interviews showed that therapists enjoyed the process and experience, valued the feedback and appreciated the support they received. Benefits and challenges of the process were identified, resulting in new initiatives being implemented. The authors confirmed that the tool achieves its intended purpose and is relevant in the home care setting.

    Bronchial asthma and diabetes mellitus type 2 are often found among adult patients. However, coincidence of these two diseases is very rare. The aim of the study was the retrospective analysis of all patients with bronchial asthma and diabetes mellitus type 2 hospitalised in Department and Clinic of Internal Diseases and Allergology in Zabrze, Silesian School of Medicine in Katowice in 1988-1997. Diabetes mellitus type 2 was diagnosed according to WHO criteria of 1985 and bronchial asthma was diagnosed with the use of American Thoracic Society criteria. Bronchial asthma and diabetes mellitus type 2 occurring together were found in 18 patients (0.3% of all hospitalized patients). In most patients the symptoms of bronchial asthma preceded the diagnosis of diabetes mellitus by a few years. All these cases were heterogeneous in terms of the duration of the diseases, clinical picture, and therapeutical approaches. In patients with bronchial asthma the existence of diabetes mellitus type 2 was not related to use of glikocorticosteroids. Patients in whom the coexistence of bronchial asthma and diabetes mellitus type 2 was found should be subjects of further studies to extend our knowledge of patomechanism of these diseases.

    The availability of newer, more sophisticated and versatile bronchoscopes has expanded the spectrum and scope of the indications for bronchoscopy in the newborn infant both for diagnostic and therapeutic purposes. The aim of this study was to carry out a retrospective analysis of the bronchoscopies performed on newborn infants, and to review the indications of this procedure in this age group. Sixty-three patients were submitted to 67 bronchoscopies in a period of 13 years, allowing the diagnosis of 45 anomalies and malformations of the tracheo-bronchial tree, and the performance of 24 bronchoalveolar lavages. In six cases, endoscopic removal of secretions helped to resolve resistant atelectasia, while in another case, with esophageal atresia, intra-operative definition of the fistula tract was possible through catheterisation of the fistula with the bronchoscope. The flexible bronchoscope was preferred for diagnosis by direct visualisation, and the rigid bronchoscope for some diagnostic and therapeutic procedures. Stridor, unexplained cyanosis, hemoptysis, persistent or recurrent pulmonary images, difficulties in the intubation or extubation, and persistent disturbances in ventilation are among the main indications for bronchoscopy in the newborn infant. Bronchoscopy also allows the performance of subsidiary techniques, such as bronchoalveolar lavage, biopsy and laser therapy.

    The records of 204 cats entering the intensive care unit (ICU) at the University of Edinburgh Small Animal Hospital between December 2002 and October 2006 were retrospectively analysed. Of these, 37 cats over 12 months of age had a systolic blood pressure recorded on entry into the ICU, and this group comprised our study population. Of these 37 cats, 36 had both heart rate and respiratory rate recorded on entry into the ICU, whilst 24 of these cats also had body temperature recorded. The relationship between (i) survival to discharge and (ii) survival until 21 days after admission to the ICU was analysed using univariate generalised linear models with binomial errors. The robustness of any significant relationship was assessed using multivariate analysis methods. In addition, receiver operator curves (ROC) were generated for any of the significant predictors of mortality and from these curves the threshold values, optimal sensitivity and specificity were calculated. Using these values survival curves were generated for any significant prognostic indexes. A decreased blood pressure at the time of admission to the ICU was found to be a significant negative predictor of survival until discharge from the hospital. Overall, a systolic blood pressure of 124 mmHg or higher at the time of admission to the ICU has a sensitivity of 47.8% and a specificity of 85.7% for predicting that a cat will survive until discharge from the hospital.

    Thirty-four unilateral below-elbow amputees from the Shriners Hospitals for Children/Twin Cities were retrospectively analyzed in long-term follow-up. All of these patients were provided with a variety of prosthetic options, including a "passive" cosmetic upper extremity device. Most of the patients were also fitted with conventional prostheses using a body-powered voluntary closing terminal device (97%) as well as myoelectric prostheses (82%). These patients were considered consistent prosthetic users by the clinic team. The average follow-up was 14 years, with many of the patients being followed up throughout their entire childhood. All patients were sent questionnaires, and the authors carried out patient interviews and chart review. Final analysis indicated that 15 patients (44%) selected a simple cosmetic "passive hand" as their prosthesis of choice. In long-term follow-up 14 patients (41%) continued as multiple users. Fourteen patients (41%) selected the conventional prosthesis using a voluntary closing terminal device as the prosthesis of choice. Only five patients (15%) selected the myoelectric device as their primary prosthesis. The authors conclude that successful unilateral pediatric amputees may choose multiple prostheses on the basis of function and that frequently the most functional prosthesis selected in the long term is the simplest in design. The authors believe strongly that unilateral pediatric amputees should be offered a variety of prosthetic options to help with normal activities of daily living.

    Full Text Available Background: In our institute, about 10% of total cancer is female breast cancer. This analysis was performed to check triple negativity among these patients with their survival strength up to 5 years in relation to different age groups, stage and chemotherapy protocols. Materials and Methods: 208 immunohistochemistry proved triple negative breast cancer patients registered and treated until 2008 were retrospectively selected for the study. Overall survival up to 5 years was observed on the basis of stage, different age groups and chemotherapy regimens. All patients had undergone surgery, conventional external beam radiation therapy and adjuvant chemotherapy. The survival analyses were performed using the Kaplan-Meier method. Results: The majority of patients (41% were in the age group 21-30 years. Stage IV was seen in 18% of the patients at diagnosis and mainly in 21-40 years age group. Only 3% of females were >70 years age and were of Stage I and II. Overall 5 year survival in Stage I in Cyclophosphamide, Adriamycin/Epirubicin, 5-Flurouracil group was 37.5% as compared with Docetaxel/Paclitaxel, Epirubicin group 93% (P < 0.0001. Conclusion: Triple negativity in North-West India is about 11.8%. We observed it in younger patients mainly with highly aggressive behaviors. Taxane based chemotherapy gives better result as compared with anthracycline based regimens in all stages.

    AIM: To investigate the causes of small intestinal bleeding as well as its diagnosis and therapeutic approaches.METHODS: A retrospective analysis was conducted according to the clinical records of 76 patients with small intestinal bleeding admitted to our hospital in the past 5 years.RESULTS: In these patients, tumor was the most frequent cause of small intestinal bleeding (37/76), followed by Meckel's diverticulum (21/76), angiopathy (15/76) and ectopic pancreas (3/76). Of the 76 patients,21 were diagnosed by digital subtraction angiography,13 by barium and air double contrast X-ray examination of the small intestine, 11 by 99mTc-sestamibi scintigraphy of the abdominal cavity, 6 by enteroscopy of the small intestine, 21 by laparoscopic laparotomy, and 4 by exploratory laparotomy. Although all the patients received surgical treatment, most of them (68/76) received part enterectomy covering the diseased segment and enteroanastomosis. The follow-up time ranged from 1 year to 5 years. No case had recurrent alimentary tract bleeding or other complications.CONCLUSION: Tumor is the major cause of small intestinal bleeding followed by Meckel's diverticulum and angiopathy. The main approaches to definite diagnosis of small intestinal bleeding include digital subtraction angiography, 99mTc-sestamibi scintigraphy of the abdominal cavity, barium and air double contrast X-ray examination of the small intestine, laparoscopic laparotomy or exploratory laparotomy. Part enterectomy covering the diseased segment and enteroanastomosis are the most effective treatment modalities for small intestinal bleeding.

    Limited information is available regarding the use of cyclosporin A (CsA) for the treatment of feline dermatoses. The aim of this retrospective study was therefore to describe the efficacy of CsA for the therapy of eosinophilic granuloma (EG), eosinophilic plaque, indolent ulcer, linear granulomas, idiopathic pruritus and stomatitis. A computer search for feline dermatological cases treated with CsA between 1999 and 2004 was performed. Based on history, clinical signs and laboratory diagnostic tests, it was then possible to divide cases into three groups and to select 23 cats. Seven cats had one or more of the following conditions: EG, eosinophilic plaque, indolent ulcer and/or linear granuloma (group A); eight cats had idiopathic pruritus (group B) and eight cats had plasmacytic stomatitis (group C). Doses ranged from 5.8 to 13.3 mg kg(-1) oral CsA. All cats were monitored, with complete serum blood analysis and physical examination, monthly for a minimum of 6 months. Response to therapy was scored (severity of lesions and pruritus) with a 0-10 visual analogue scale at each visit (day 0, day, 30, day 60, day 90). All cats in groups A and B were cured and were maintained on alternate day therapy. In group C, 4/8 patients went into remission, while remaining cats have a fair to good improvement. Routine haematological and biochemical examination failed to reveal abnormalities related to CsA administration.

    We used stable isotope analysis to investigate the foraging ecology of coastal bottlenose dolphins (Tursiops truncatus) in relation to a series of anthropogenic disturbances. We first demonstrated that stable isotopes are a faithful indicator of habitat use by comparing muscle isotope values to behavioral foraging data from the same individuals. δ13C values increased, while δ34S and δ15N values decreased with the percentage of feeding observations in seagrass habitat. We then utilized stable isotope values of muscle to assess temporal variation in foraging habitat from 1991 to 2010 and collagen from tooth crown tips to assess the time period 1944 to 2007. From 1991 to 2010, δ13C values of muscle decreased while δ34S values increased indicating reduced utilization of seagrass habitat. From 1944 to 1989 δ13C values of the crown tip declined significantly, likely due to a reduction in the coverage of seagrass habitat and δ15N values significantly increased, a trend we attribute to nutrient loading from a rapidly increasing human population. Our results demonstrate the utility of using marine mammal foraging habits to retrospectively assess the extent to which anthropogenic disturbance impacts coastal food webs.

    Maintenance care is the most important part of periodontal treatment because maintenance - adherence to the schedule of recall dental appointments after treatment - is believed to be the key in preventing the recurrence of periodontal disease. This article is a retrospective analysis of 315 cases from the Department of Periodontics and Preventive Dentistry at the University of Pittsburgh to determine compliance with periodontal maintenance schedules over a two-year period. Following the completion of periodontal surgical treatment, patients were placed on a regimen of maintenance care that included recalls every three months, professional prophylaxis by the hygiene faculty, and repeated instructions in home self-care. Medical records and patient charts of 315 subjects were selected randomly and reviewed in terms of the patient's attending the scheduled recall visit. It was hypothesized that female subjects would show better compliance with the maintenance care regimen than male subjects, as suggested in the literature. Among the 315 subjects, 112 (54 women and 58 men) followed the recommended recall schedule; 30% ultimately returned for the three-month prophylaxis recall visit after the initial periodontal surgical appointment, and thus were considered to have complied with the suggested maintenance program. The investigators failed to reject the stated hypothesis that women would display better compliance than men (p = 0.3).

    Full Text Available Background. The purpose of this study was to report on any prognostic factors that had a significant effect on clinical outcomes following arthroscopic Type II SLAP repairs. Methods. Consecutive patients who underwent arthroscopic Type II SLAP repair were retrospectively identified and invited to return for follow-up examination and questionnaire. Statistical analysis was performed to determine associations between potential prognostic factors and failure of SLAP repair as defined by ASES of less than 50 and/or revision surgery. Results. Sixty-two patients with an average age of years met the study criteria with a mean followup of 3.3 years. There were statistically significant improvements in mean ASES score, forward elevation, and external rotation among patients. Significant associations were identified between ASES score less than 50 and age greater than 40 years; alcohol/tobacco use; coexisting diabetes; pain in the bicipital groove on examination; positive O’Brien’s, Speed’s, and/or Yergason’s tests; and high levels of lifting required at work. There was a significant improvement in ASES at final followup. Conclusions. Patients younger than 20 and overhead throwers had significant associations with cases requiring revision surgery. The results from this study may be used to assist in patient selection for SLAP surgery.

    Full Text Available Decitabine has been approved for the treatment of all subtypes of myelodysplastic syndrome (MDS. However, the optimal regimen for decitabine treatment is not well established. In this study, an observational, retrospective and multi-center analysis was performed to explore the decitabine schedule for the treatment of MDS. A total of 79 patients received reduced dosage decitabine treatment (15 mg/M2/day intravenously for five consecutive days every four weeks. Fifty-three out of the 79 patients were defined as intermediate-2/high risk by international prognostic scoring system (IPSS risk category. 67.1% of MDS patients achieved treatment response including complete response (CR (n = 23, Partial response (n = 1, marrow CR (mCR with hematological improvement (HI (n = 11, mCR without HI (n = 11 and HI alone (n = 7 with a median of 4 courses (range 1-11. The median overall survival (OS was 18.0 months. The median OS was 22.0, 17.0 and 12.0 months in the patients with CR, those with other response, and those without response, respectively. In addition, this regimen contributed to zero therapy-related death and punctual course delivery, although III or IV grade of cytopenia was frequently observed. In conclusion, the 15 mg/M2/d×5 day decitabine regimen was effective and safe for Chinese MDS patients with IPSS score of 0.5 or higher.

    This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system. The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated. Eighty-five (54 %) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70 %) and 124 (79 %) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5 %) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83 % after 5 years. The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates. (orig.)

    Full Text Available The problem of the risks of drug abuse as a form of deviant behavior in the context of adolescence. In this study deviant behavior appears as actions (or willingness to commit them, contrary to the generally accepted cultural and moral values, as well as socio-psychological and legal norms, including the abuse of alcohol, drugs and other psychoactive substances Study prerequisites for the formation of drug addiction in adolescence age allows us to trace the link between awareness about drugs and those at risk of developing dependence on them, which are due to the age and psychological characteristics described L.S. Vygotsky and other scientists working in the paradigm of cultural-historical psychology. The article hypothesized that narcogene information can act as a factor of risk of drug use. It is argued that the basis of the commission of a narcotic substance samples is narcogene information and control over the sources that may contribute to the prevention of mass anesthesia teenagers. This assertion is supported by the results of a retrospective study of social and psychological factors in the emergence of drug abuse conducted in the Kabardino-Balkaria republic dispensary, which was attended by 24 active addict aged 18-28 who are registered with the method of questioning.Purpose. To study the role of information on drugs and drug addiction in the range of solutions «for» or «against» in a situation narcogene risk.Methodology. Questioning of active drug abusers.Results. Based on a retrospective analysis of risk factors for drug abuse as a form of deviant behavior found that narcogene information may lead to introduction to drugs. Lack of knowledge about the effects of drugs on the human body, and the temptation to create a stable, creates a high risk on narcotics debut. Drug use leads to a decrease of expression of fear and inadequate assessment of the degree of its danger. It creates a false impression that the drug is easy to give

    Based on estimates from the U.S. Consumer Product Safety Commission (CPSC), there were about 25,000 baby walker-related injuries treated annually in U.S. hospital emergency departments during the early 1990s. This amounted to about 8 injuries for every 1000 baby walkers in use. Most injuries resulted from falls down stairs. After CPSC initiated a regulatory proceeding in 1994, the CPSC staff worked with industry to address the stair-fall hazard. This cooperative effort resulted in requirements designed to prevent stair-fall injuries that became effective in 1997 as part of a revised voluntary safety standard. This study presents a retrospective benefit-cost analysis of the 1997 stair-fall requirements. The benefits were defined as the reduction in the costs of injuries resulting from the use of the safer walkers. The costs were defined as the additional resource costs associated with making baby walkers safer. The study found that the stair-fall requirements were highly effective in reducing the risk of stair-fall injury, and that the benefits of the requirements substantially exceeded the costs. The expected net benefits (i.e., benefits minus costs) amounted to an average of about $169 per walker, over the walker's expected product life. Given current U.S. sales of about 600,000 baby walkers annually, the present value of the expected net benefits associated with 1 year's production amounts to over $100 million annually. A sensitivity analysis showed that the major findings were robust with respect to variations in underlying assumptions.

    Invasive aspergillosis is an important cause of morbidity and mortality in haematological patients. Current guidelines recommend voriconazole as first-line therapy. A change in class of antifungal agent is generally recommended for salvage therapy. The focus of this analysis was to assess if posaconazole is suitable for salvage therapy following voriconazole treatment. This was a retrospective investigation on patients with sequential antifungal therapy of posaconazole after voriconazole identified at four German hospitals. Response rates at 30 and 60 days following start of posaconazole application and toxicity of azoles by comparing liver enzymes and cholestasis parameters were evaluated. Data were analysed by descriptive statistics. Overall, the success rate was 72.2% [15 of 36 patients showed complete response (41.7%), 11 patients partial response (30.6%) at any time point], eight patients failed treatment and two were not evaluable. Mean laboratory values increased during voriconazole and decreased during posaconazole treatment: aspartate aminotransferase (increase: 31.9 U l(-1) vs. decrease: 19.6 U l(-1) ), alanine aminotransferase (32.4 U l(-1) vs. 19.8 U l(-1) ), gamma-glutamyl transferase (124.2 U l(-1) vs. 152.3 U l(-1) ) and alkaline phosphatase (71.5 U l(-1) vs. 40.3 U l(-1) ) respectively. No patient discontinued posaconazole therapy due to an adverse event. In this analysis posaconazole was a safe and effective antifungal salvage therapy in patients with prior administration of another triazole.

    Familial cases of medullary thyroid carcinoma (MTC) may be diagnosed by genetic screening, while in sporadic tumors the diagnosis relies mainly on fine-needle aspiration cytology. The aim of the present study was to determine the demographic, clinical and pathological characteristics of MTC patients followed-up at the Portuguese Institute of Oncology Francisco Gentil (Lisbon, Portugal). For that purpose, a retrospective analysis of 140 MTC patients diagnosed between 1990 and 2010 was performed. The results indicated that patients with hereditary MTC (11.4%) were significantly younger than patients with sporadic MTC. Of the latter, 34.3% had no clinical suspicion of MTC prior to surgery. The sensitivity of cytology and calcitonin (CT) assay in diagnosing MTC were 51.3 and 98.7%, respectively. All familial index cases and 69.0% of sporadic cases presented with advanced stage disease at the time of diagnosis, while 73.0% of familial MTC detected by genetic/pentagastrin screening were diagnosed at the early stage of the disease. Biochemical cure (BC) was achieved in 39.7% of patients and, of these, only 6.5% relapsed. The 5 and 10-year survival rates were 79.3 and 73.6%, respectively. Age >45 years (P=0.026), advanced stage at diagnosis (P<0.001) and absence of BC (P<0.001) were predictors of a worse prognosis on univariate analysis. However, when the patients detected by genetic/pentagastrin screening were excluded from the analysis, age was no longer a prognostic factor, although disease stage remained a significant prognostic factor. On multivariate analysis, BC was the only factor with a significant impact on prognosis (P=0.031). In addition, the present study confirmed that the majority of patients were diagnosed at advanced stages, and CT determination was observed to be more sensitive than cytology to diagnose MTC. Patients at early stages were more prone to achieve BC, which was a favorable prognostic factor. To the best of our knowledge, the present study

    Xanthene dyes can be appended to cyclodextrins via an ester or amide bridge in order to switch the fluorescence on or off. This is made possible through the formation of nonfluorescent lactones or lactams as the fluorophore can reversibly cyclize. In this context we report a green approach for the synthesis of switchable xanthene-dye-appended cyclodextrins based on the coupling agent 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMT-MM). By using 6-monoamino-β-cyclodextrin and commercially available inexpensive dyes, we prepared rhodamine- and fluorescein-appended cyclodextrins. The compounds were characterized by NMR and IR spectroscopy and MS spectrometry, their UV-vis spectra were recorded at various pH, and their purity was determined by capillary electrophoresis. Two potential models for the supramolecular assembly of the xanthene-dye-appended cyclodextrins were developed based on the set of data collected by the extensive NMR characterization.

    Full Text Available Abstract Solitary caecal diverticulum is an uncommon entity and therefore difficult to diagnose except at surgery. Caecal diverticulitis is an infrequent cause of acute abdomen and usually presents in a manner similar to acute appendicitis. It is extremely difficult to differentiate it preoperative from acute appendicitis and such distinction is usually made in the operating room. The optimal management of this clinical condition is still controversial, ranging from conservative treatment with antibiotics to aggressive surgical resections. We report a case of a 61 year old Caucasian who presented with acute onset right iliac fossa pain indistinguishable from acute appendicitis. The true diagnosis of a perforated acute caecal diverticulitis with an abscess mass was only made at operation in the presence of a macroscopically normal appendix. We reviewed the literature to highlight the difficulty of a preoperative diagnosis and the need for a high index of suspicion especially in the older age group presenting in manner similar to acute appendicitis.

    During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complications. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-ups in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examinations in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examinations in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis (n=5) and perforated appendicitis (n=1). Our results show that high-resolution, real-time US is an accurate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complications.

    Full Text Available PURPOSE: To describe the risk factors and labor characteristics of Clavicular fracture (CF and brachial plexus injury (BPI; and compare antenatal and labor characteristics and prognosis of obstetrical BPI associated with shoulder dystocia with obstetrical BPI not associated with shoulder dystocia. METHODS: This retrospective study consisted of women who gave birth to an infant with a fractured clavicle or BPI between January 2009 and June 2013. Antenatal and neonatal data were compared between groups. The control group (1300 was composed of the four singleton vaginal deliveries that immediately followed each birth injury. A multivariable logistic regression model, with backward elimination, was constructed in order to find independent risk factors associated with BPI and CF. A subgroup analysis involved comparison of features of BPI cases with or without associated shoulder dystocia. RESULTS: During the study period, the total number of vaginal deliveries was 44092. The rates of CF, BPI and shoulder dystocia during the study period were 0,6%, 0,16% and 0,29%, respectively. In the logistic regression model, shoulder dystocia, GDM, multiparity, gestational age >42 weeks, protracted labor, short second stage of labor and fetal birth weight greater than 4250 grams increased the risk of CF independently. Shoulder dystocia and protracted labor were independently associated with BPI when controlled for other factors. Among neonates with BPI whose injury was not associated with shoulder dystocia, five (12.2% sustained permanent injury, whereas one neonate (4.5% with BPI following shoulder dystocia sustained permanent injury (p = 0.34. CONCLUSION: BPI not associated with shoulder dystocia might have a higher rate of concomitant CF and permanent sequelae.

    Full Text Available Background: Androgen insensitivity syndrome (AIS or testicular feminization is a partial or complete inability of cell response to androgen. The cause is enzymatic defect in synthesis of testosterone, resulting sexually immature phenotypically female, with primary amenorrhea. There are three categories of AIS, complete, partial and mild, depending on the degree of external genital masculinization. The aim of this study was to find out chromosomal abnormalities, and correlation between AIS and maternal/paternal age, parents' consanguineous marriage, family history and clinical observation, in Iranian AIS patients.  Method: This study includes a retrospective data analysis of 72,000 families' medical records in the Genetic Clinic in Tehran, during a 30-yr period (1984-2014. The essential basis for the patients' referral to the clinic by gynecologists was primary amenorrhea. Cytogenetic abnormalities has been confirmed by chromosome G-banding and conventional staining methods.Results: Seventy AIS female patients with 46XY pattern were cytogenetically diagnosed and the frequency of AIS syndrome was estimated about 0.05% (~70/140000. The results showed no association between AIS and maternal or paternal age nor were the marital pattern of the parents. The clinical findings illustrated that primary amenorrhea had the highest indication for referral of AIS patients for genetic counseling and cytogenetic study.Conclusion: No correlation was observed between AIS and maternal or paternal age or consanguineous marriages. Amenorrhea is the most clinically observed sign of AIS patients.  Keywords: Androgen insensitivity syndrome (AIS, Testicular feminization, Human androgen receptor (HAR, Amenorrhea, Iran

    Objectives To establish the pattern of change in individual scientific production over the career of medical researchers. Design Retrospective cohort based on prospectively collected data in a hospital information system. Setting Multicentre university hospital in France. Participants Two distinct populations of 1835 researchers (full professors vs non-academic physicians) having produced 44 723 publications between 1995 and 2014. Main outcome measures Annual number of publications referenced in Medline/PubMed with a sensitivity analysis based on publications as first/last author and in high impact journals. The individual volume of publications was modelled by age using generalised estimating equations adjusted for birth cohort, biomedical discipline and academic position of researchers. Results Averaged over the whole career, the annual number of publications was 5.28 (95% CI 4.90 to 5.69) among professors compared to 0.82 (95% CI 0.76 to 0.89) among non-academic physicians (pcareer (0.90, 95% CI 0.77 to 1.06). The non-academic physicians experienced a slower pace of learning curve at the beginning of their careers (42.38, 95% CI 25.37 to 70.81) followed by a smaller increase in the annual number of publications (1.29, 95% CI 1.11 to 1.51). Conclusions Compared to full professors, non-academic physicians had a poor capacity to publish, indicating a low productivity when medical doctors have limited time or little interest in undertaking research. This finding highlights the potential for rethinking the missions of medical doctors towards an enlargement of scientific prerogatives in favour of progress in global knowledge. PMID:28237957

    In 2010, China was responsible for nearly 20 percent of global energy use and 25 percent of energy-related carbon dioxide (CO2) emissions. Unlike most countries, China’s energy consumption pattern is unique because the industrial sector dominates the country’s total energy consumption, accounting for about 70 percent of energy use and 72 percent of CO2 emissions in 2010. For this reason, the development path of China’s industrial sector will greatly affect future energy demand and dynamics of not only China, but the entire world. A number of analyses of historical trends have been conducted, but careful projections of the key factors affecting China’s industry sector energy use over the next decade are scarce. This study analyzes industrial energy use and the economic structure of the Chinese manufacturing sector in detail. First, the study analyzes the energy use of and output from 18 industry sub-sectors. Then, retrospective (1995-2010) and prospective (2010-2020) decomposition analyses are conducted for these industrial sectors in order to show how different factors (production growth, structural change, and energy intensity change) influenced industrial energy use trends in China over the last 15 years and how they will do so over the next 10 years. The results of this study will allow policy makers to quantitatively compare the level of structural change in the past and in the years to come and adjust their policies if needed to move towards the target of less energy-intensive industries. The scenario analysis shows the structural change achieved through different paths and helps to understand the consequences of supporting or limiting the growth of certain manufacturing subsectors from the point of view of energy use and structural change. The results point out the industries that have the largest influence in such structural change

    Full Text Available Abstract Background Patients ingesting ethylene glycol, isopropanol, methanol, and propylene glycol ('toxic alcohols' often present with non-specific signs and symptoms. Definitive diagnosis of toxic alcohols has traditionally been by gas chromatography (GC, a technique not commonly performed on-site in hospital clinical laboratories. The objectives of this retrospective study were: 1 to assess the diagnostic accuracy of the osmolal gap in screening for toxic alcohol ingestion and 2 to determine the common reasons other than toxic alcohol ingestion for elevated osmolal gaps. Methods Electronic medical records from an academic tertiary care medical center were searched to identify all patients in the time period from January 1, 1996 to September 1, 2010 who had serum/plasma ethanol, glucose, sodium, blood urea nitrogen, and osmolality measured simultaneously, and also all patients who had GC analysis for toxic alcohols. Detailed chart review was performed on all patients with osmolal gap of 9 or greater. Results In the study period, 20,669 patients had determination of serum/plasma ethanol and osmolal gap upon presentation to the hospitals. There were 341 patients with an osmolal gap greater than 14 (including correction for estimated contribution of ethanol on initial presentation to the medical center. Seventy-seven patients tested positive by GC for one or more toxic alcohols; all had elevated anion gap or osmolal gap or both. Other than toxic alcohols, the most common causes for an elevated osmolal gap were recent heavy ethanol consumption with suspected alcoholic ketoacidosis, renal failure, shock, and recent administration of mannitol. Only 9 patients with osmolal gap greater than 50 and no patients with osmolal gap greater than 100 were found to be negative for toxic alcohols. Conclusions Our study concurs with other investigations that show that osmolal gap can be a useful diagnostic test in conjunction with clinical history and physical

    The purpose of this study was to retrospectively investigate the efficacy of multidisciplinary therapy (concomitant radiotherapy and intra-arterial infusion of 5-fluorouracil (5-FU) followed by maxillectomy) in the treatment of squamous cell carcinoma of the maxillary sinus. We reviewed 71 patient records with locally advanced but respectable carcinoma of the maxillary sinus treated by means of multidisciplinary therapy between 1978 through 1997. The clinical T factor for these patients, according to the UICC definitions (1997), was 12 for T2, 46 for T3, and 13 for T4. Twelve patients were diagnosed as node-positive at initial presentation. Intra-arterial 5-FU was delivered via a superficial temporal artery in accordance with radiotherapy, and the cumulative 5-FU dose ranged from 2,900 mg to 5,250 mg (median 5,000 mg). The total radiotherapy dose ranged from 29 Gy to 48 Gy (median 48 Gy) with conventional fractionation. Patients underwent radical maxillectomy thereafter. The 5-year overall survival rate and disease-specific survival rate of all the patients were 58% and 68%, respectively. There was no significant correlation of clinical T factor or N factor with disease-specific survival on univariate and multivariate analysis. The overall treatment-related mortality rate was 3.7%. Radiation cataract later developed in all evaluable patients whose lenses were within the treatment volume. About a half of the operable T4 patients survived over 5 years by means of the above-mentioned multidisciplinary therapy. This multidisciplinary therapy should be compared to treatment with a combination of surgery and postoperative chemoradiotherapy. (author)

    Full Text Available Abstract Background From 1995-2000 the under five mortality rate in Uganda increased from 147.3 to 151.5 deaths per 1000 live births and reasons for the increase were not clear. This study was undertaken to understand factors influencing the increase in under five mortality rate during 1995-2000 in Uganda with a view of suggesting remedial actions. Methods We performed a comparative retrospective analysis of data derived from the 1995 and the 2000 Uganda demographic and health surveys. We correlated the change of under five mortality rate in Uganda desegregated by region (central, eastern, north and western with change in major known determinants of under five mortality such social economic circumstances, maternal factors, access to health services, and level of nutrition. Results The increase in under five mortality rate only happened in western Uganda with the other 3 regions of Uganda (eastern, northern and central showing a decrease. The changes in U5MR could not be explained by changes in poverty, maternal conditions, level of nutrition, or in access to health and other social services and in the prevalence of HIV among women attending for ante-natal care. All these factors did not reach statistical significance (P > 0.05 using Pearson's correlation coefficient. Conclusion In order to explain these findings, there is need to find something that happened in western Uganda (but not other parts of the country during the period 1995-2000 and has the potential to change the under five mortality by a big margin. We hypothesize that the increase in under five mortality could be explained by the severe malaria epidemic that occurred in western Uganda (but not other regions in 1997/98.

    Full Text Available Aims: The aim of this study was to determine the incidence of humans being bitten by rabies-suspected animals, and the victims′ adherence to post-exposure prophylaxis (PEP regimen. Materials and Methods: A retrospective analysis of data of victims treated at Bugando Medical Centre during the period 2002-2006 (n=5 years was done. Results: A total of 767 bite injuries inflicted by rabies-suspected animals were reported, giving a mean annual incidence of ~58 cases per 100,000 (52.5% males, 47.5% females. The proportion of children bitten was relatively higher than that of adults. All victims were treated by using inactivated diploid-cell rabies vaccine and were recommended to appear for the second and third doses. However, only 28% of the victims completed the vaccination regime. Domestic dogs were involved in 95.44% of the human bite cases, whereas cats (3.9%, spotted hyena (Crocuta crocuta (0.03%, vervet monkey (Cercopithecur aethiops (0.01% and black-backed jackal (0.01% played a minor role. The majority of rabies-suspected case reports were from Nyamagana district and occurred most frequently from June to October each year. Conclusions: In conclusion, this study revealed that incidences of humans being bitten by dogs suspected of rabies are common in Tanzania, involve mostly children, and victims do not comply with the prophylactic regimen. Rigorous surveillance to determine the status of rabies and the risk factors for human rabies, as well as formulation and institution of appropriate rabies-control policies, is required.

    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.

    OBJECTIVE: Bile leakage, while rare, can be a complication seen after cholecystectomy. It may also occur after hepatic or biliary surgical procedures. Etiology may be underlying pathology or surgical complication. Endoscopic retrograde cholangiopancreatography (ERCP) can play major role in diagnosis and treatment of bile leakage. Present study was a retrospective analysis of outcomes of ERCP procedure in patients with bile leakage. METHODS: Patients who underwent ERCP for bile leakage after surgery between 2008 and 2012 were included in the study. Etiology, clinical and radiological characteristics, and endoscopic treatment outcomes were recorded and analyzed. RESULTS: Total of 31 patients (10 male, 21 female) were included in the study. ERCP was performed for bile leakage after cholecystectomy in 20 patients, after hydatid cyst operation in 10 patients, and after hepatic resection in 1 patient. Clinical signs and symptoms of bile leakage included abdominal pain, bile drainage from percutaneous drain, peritonitis, jaundice, and bilioma. Twelve (60%) patients were treated with endoscopic sphincterotomy (ES) and nasobiliary drainage (NBD) catheter, 7 patients (35%) were treated with ES and biliary stent (BS), and 1 patient (5%) was treated with ES alone. Treatment efficiency was 100% in bile leakage cases after cholecystectomy. Ten (32%) cases of hydatid cyst surgery had subsequent cystobiliary fistula. Of these patients, 7 were treated with ES and NBD, 2 were treated with ES and BS, and 1 patient (8%) with ES alone. Treatment was successful in 90% of these cases. CONCLUSION: ERCP is an effective method to diagnose and treat bile leakage. Endoscopic treatment of postoperative bile leakage should be individualized based on etiological and other factors, such as accompanying fistula. PMID:28058396

    Objective The purpose of this study was to describe the demographics, presenting complaints, and health history of new patients seeking treatment at a free chiropractic clinic within a university health center. Methods A retrospective analysis of patient files from 2008 to 2009 was performed for a free student chiropractic clinic in the Buffalo, NY, area. Demographics, presenting complaints, and health history of new patients seeking treatment were recorded. Results There were 343 new chiropractic patient files. Most patients were between the ages of 18 and 30 years (n = 304, 88%) with an almost equal distribution of men (n = 163, 48%) and women (n = 180, 52%). The patients were mostly single (n = 300, 87%). Patients self-reported that their case histories excluded a current medical diagnosis (n = 261, 76%), previous history of disease (n = 216, 63%), allergies (n = 240, 70%), previous surgical procedures (n = 279, 81%), and medication use (n = 250, 73%). The frequencies of spinal complaints were as follows: lumbar spine, n = 176 (51%); cervical spine, n = 78 (23%); and thoracic spine, n = 44 (13%). Maintenance care, headaches, and spine-related upper and lower extremities complaints accounted for the other 13% of patients treated. Half were chronic (n = 172, 50%), and a third were acute (n=108, 31%). Patients averaged 6 chiropractic visits, with 88% having 11 visits or less. Conclusion This study found that new patients seeking care at a free student chiropractic clinic within a university health center in the Buffalo area mainly consisted of young single adults, with chronic lumbar spine complaints with few comorbidities.

    Full Text Available Background: Deep venous thrombosis (DVT of lower limbs is one of the most common cause for the majority of deaths caused by pulmonary embolism. Many medical and surgical disorders are complicated by DVT. Most venous thrombi are clinically silent. B-mode and color Doppler imaging is needed for early diagnosis of DVT to prevent complications and sequalae of DVT. Aim and Objectives: The objectives of the following study were to evaluate the role of Doppler as an imaging modality in diagnosing DVT of lower limbs, to study the spectrum of findings on Doppler ultrasound in patients with DVT. Materials and Methods: Retrospective descriptive analysis of 78 patients of DVT diagnosed on Doppler. Results: Nearly 74% of the patients were males and 26% were females with majority belonging to fifth decade (26%. 75 (96.1% cases showed unilateral while 3 (3.9% cases showed bilateral lower limb involvement. In our study, predominant distribution of thrombus was found to be in above knee region with 69/78 (88.5% patients having thrombus in the superficial femoral vein. Popliteal vein was involved in 54/78 (69.2% patients. Complete thrombosis was observed in 54/78 (69% cases, while partial thrombosis was observed in 24/78 (31% cases. Subacute stage was seen in 42 cases (53.8%, acute stage in 23 cases (29.5% while chronic stage in 13 cases (16.7%. 71 cases (91% had multiple contiguous segmental involvement, whereas 7 cases (9% had isolated vein involvement. Conclusion: Color Doppler is useful in diagnosing DVT in symptomatic and at risk patients and provides a non-invasive method of investigation. It is also helpful in evaluating the site, extent and stage of thrombus.

    Full Text Available Background Kidney transplantation has long been recognized as the best available therapy for end stage kidney disease. Objectives This study aimed to compare outcomes of double-J versus percutaneous ureteral stent placement in renal transplantation. Patients and Methods A retrospective analysis was performed on data of renal transplantations performed at our institution in a 12-month period. In this period, external and double-J stents were used in parallel. Length of hospital stay and stent-associated complications were evaluated. Results In 76 kidney transplants, 43 external (group 1 and 33 double-J (group 2 urinary stents were used. No significant difference was observed in the number of urinary tract infections, ureteric stenosis or necrosis. The mean overall length of hospital stay was comparable in both groups (20.7 days in group 1 vs 19.3 days in group 2, P = 0.533. For patients without immunological complications, the hospital stay was significantly reduced using double-J stents (12.9 days in group 1, 10.8 days in group 2, P = 0.018. Leakage of the ureteroneocystostomy occurred in 6 out of 43 patients in group 1 (13.9%. No case of anastomotic insufficiency was observed in group 2 (P = 0.035. Macrohematuria was detected in 13 out of the 43 patients in group 1 (30.2%, compared to 3 out of 33 patients in group 2 (9.1%; P = 0.045. Conclusions This nonrandomized comparison of stent types in kidney transplantation supports the use of prophylactic double-J stents in terms of decreased ureteric complications and reduced length of hospital stay.

    Full Text Available Background Granulomatous mastitis is a rare and benign inflammatory breast disease that may clinically and radiologically mimic breast cancer. Objectives The aim of this study was to evaluate the features of idiopathic granulomatous mastitis (IGM on breast magnetic resonance imaging (MRI with mammographic and sonographic findings. Patients and Methods A retrospective analysis was conducted on 20 patients with IGM who had been diagnosed by needle core or excisional biopsy at a single institution between 2006 and 2012. All of the patients underwent MRI for suspicious breast findings prior to biopsy. MRI examinations were performed on a 1.5 T scanner. The MRI findings were evaluated in accordance with the breast imaging-reporting and data system (BI-RADS MRI lexicon established by the American College of Radiology. Results MRI detected a total of 29 lesions in the 20 patients. Fourteen of these lesions were seen as mass enhancements, with the remaining 15 identified as non-mass enhancements (NMEs. The median size of all lesions was 3.6 cm (range, 0.7 - 6.7 cm. The most frequently observed features were masses with a round shape (9 out of 14, 64%, smooth contour (11 out of 14, 78%, and a rim enhancement pattern (10 out of 14, 71%. The most common features of the 15 NME lesions were segmental distribution (6 out of 15, 40% and heterogeneous enhancement patterns (8 out of 15, 53%. The time-intensity curves of the dynamic studies showed benign type one signal intensity (persistent enhancement pattern in the majority of lesions (10 out of 20, 50%. Conclusion Our study suggests that breast MRI findings of IGM have a wide spectrum. Rim enhancement patterns are frequently seen on contrast enhanced images, but the imaging findings are nonspecific and cannot be used definitively to distinguish between benign and malignant lesions.

    Objectives To identify trends in concurrent use of a benzodiazepine and an opioid and to identify the impact of these trends on admissions to hospital and emergency room visits for opioid overdose.Design Retrospective analysis of claims data, 2001-13.Setting Administrative health claims database.Participants 315 428 privately insured people aged 18-64 who were continuously enrolled in a health plan with medical and pharmacy benefits during the study period and who also filled at least one prescription for an opioid.Interventions Concurrent benzodiazepine/opioid use, defined as an overlap of at least one day in the time periods covered by prescriptions for each drug. Main outcome measures Annual percentage of opioid users with concurrent benzodiazepine use; annual incidence of visits to emergency room and inpatient admissions for opioid overdose.Results 9% of opioid users also used a benzodiazepine in 2001, increasing to 17% in 2013 (80% relative increase). This increase was driven mainly by increases among intermittent, as opposed to chronic, opioid users. Compared with opioid users who did not use benzodiazepines, concurrent use of both drugs was associated with an increased risk of an emergency room visit or inpatient admission for opioid overdose (adjusted odds ratio 2.14, 95% confidence interval 2.05 to 2.24; Pbenzodiazepine/opioid use could reduce the risk of emergency room visits related to opioid use and inpatient admissions for opioid overdose by an estimated 15% (95% confidence interval 14 to 16).Conclusions From 2001 to 2013, concurrent benzodiazepine/opioid use sharply increased in a large sample of privately insured patients in the US and significantly contributed to the overall population risk of opioid overdose.

    Full Text Available BACKGROUND: Lactic acidosis is a common cause of high anion gap metabolic acidosis. Sodium bicarbonate may be considered for an arterial pH <7.15 but paradoxically depresses cardiac performance and exacerbates acidosis by enhancing lactate production. This study aimed to evaluate the cause and mortality rate of lactic acidosis and to investigate the effect of factors, including sodium bicarbonate use, on death. METHODS: We conducted a single center analysis from May 2011 through April 2012. We retrospectively analyzed 103 patients with lactic acidosis among 207 patients with metabolic acidosis. We used SOFA and APACHE II as severity scores to estimate illness severity. Multivariate logistic regression analysis and Cox regression analysis models were used to identify factors that affect mortality. RESULTS: Of the 103 patients with a mean age of 66.1±11.4 years, eighty-three patients (80.6% died from sepsis (61.4%, hepatic failure, cardiogenic shock and other causes. The percentage of sodium bicarbonate administration (p = 0.006, catecholamine use, ventilator care and male gender were higher in the non-survival group than the survival group. The non-survival group had significantly higher initial and follow-up lactic acid levels, lower initial albumin, higher SOFA scores and APACHE II scores than the survival group. The mortality rate was significantly higher in patients who received sodium bicarbonate. Sodium bicarbonate administration (p = 0.016 was associated with higher mortality. Independent factors that affected mortality were SOFA score (Exp (B = 1.72, 95% CI = 1.12-2.63, p = 0.013 and sodium bicarbonate administration (Exp (B = 6.27, 95% CI = 1.10-35.78, p = 0.039. CONCLUSIONS: Lactic acidosis, which has a high mortality rate, should be evaluated in patients with metabolic acidosis. In addition, sodium bicarbonate should be prescribed with caution in the case of lactic acidosis because sodium bicarbonate

    This report presents a retrospective overview of the greenhouse gas (GHG) emission trends in Europe from 1990 to 2008, with a particular focus on the underpinning drivers and the influence of EU policies. The analysis is based on the combination of decomposition analyses to identify the respective influence of each identified driver and an overview of the main EU policies and their likely effects on these drivers. The period covered by the analysis stops in 2008. As a result, the analysis avoids the effects of the recent economic crisis on GHG emissions. This reinforces the conclusion on long-term emission drivers. The report covers the EU-27 and presents results for the other EEA member countries (Iceland, Liechtenstein, Norway, Switzerland and Turkey) and Croatia (EU candidate country together with Turkey) as far as data is available. The results can be summarized as: 1) Overall GHG emission trends. EU GHG emissions were reduced between 1990 and 2008. Most of the reductions took place in the 1990s, but emissions have also been decreasing every year from 2003 until the last year considered in this report, 2008. 2) Predominant drivers. For the most part, the GHG emission trends observed in the EU between 1990 and 2008 resulted from economic factors. However, EU policies, some of which were not directly targeting GHG emissions, as well as national policies by some front runner countries, also played a role in these trends. 3) Impacts of EU policies. Between 2000 and 2008, emission trends were more directly targeted by a range of energy and climate policies, e.g. the implementation of the European Climate Change programme. However, the steady increase in energy demand during this period - particularly electricity - outweighed the considerable EU-wide savings generated by energy efficiency improvements and the development of renewable energy. 4) Co-benefits. Taking example from the positive benefits on GHG emissions that resulted from the implementation of non

    Due to the rarity of spinal cord gliomas, no consensus has been reached regarding the optimal treatment strategy. The aim of the present retrospective study was to identify patient and tumor characteristics and to evaluate the effectiveness of radiotherapy within this setting. Patients diagnosed with spinal cord gliomas between 2003 and 2013 and treated at the Department of Radiation Oncology, University of Munich, were retrospectively analyzed. Overall survival was estimated with the Kaplan-Meier method and univariate analysis was performed by log-rank testing. A total of 16 patients were identified. The cohort consisted of seven primary spinal cord gliomas and eight cases of metastases of cerebral gliomas. Median follow-up was 42 months and median total radiation dose was 45.0 Gy. In all, 62.5 % of patients received a simultaneous chemotherapy with temozolomide. The median overall survival was 6 months (95% CI: 0-27.5 months). Surgical resection of the tumor was a significant predictor of improved survival, compared with radiotherapy alone (p = 0.001). Patients with the diagnosis of a primary spinal cord glioma survived significantly longer than those presenting with a metastatic deposit from a cerebral glioma (p < 0.001). A statistically significant dose-response relationship at dose levels of ≥ 45 Gy vs. < 45 Gy could be derived (p < 0.001). Simultaneous chemotherapy did not influence survival outcome. Despite the aggressive treatment in the present study, the prognosis for spinal cord gliomas was still poor, with a median overall survival of 6 months. To the best of our knowledge, this is the largest study reporting the results of simultaneous chemoradiation in spinal cord gliomas. A combined chemoradiation treatment seems feasible and can be considered as a new treatment option in the management of spinal cord gliomas. (orig.)

    been decommissioned despite being in operation for more than 20 years, favoring from new, detailed and hard-to-follow agreements in the legislation. All wind parks that are currently in operation have received feed-in tariffs since they connected to the grid, and are expected to keep receiving them at least until December 2019, and up to December 2036 - depending on year of connection and agreement under the most recent legislation (Diario da Republica 2013). The 2020 renewable energy goals in Portugal include having 6.8 GW of installed wind capacity, which implies the connection of 2 GW in the next years. If no further grid investments are made and wind capacity increases up to 100 MW to the connection point that we analyze, total annual electricity spill is likely to range the 20% to 40%. If the connection grid policy is designed to allow for wind spill, already 'occupied' connection points will be available to new entrants, lowering the total investment costs for new wind parks and increasing their profitability. This thesis is divided in three main parts: a first introductory section, a retrospective study of wind power in Portugal and a prospective analysis of the Portuguese wind power sector. The introductory section is a brief overview of the global renewable status, described in Chapter 1. Chapter 2 and Chapter 3 compile a retrospective study of wind power and the policies that have incentivized wind diffusion. We include in the discussion some references to the future wind power goals, but the results and policy recommendations are directed towards the existing connected wind power capacity.

    BACKGROUND: Anti-epilepsy and anti-psychosis drugs have traditionally been used in the clinic to treat epilepsy complicated by mental disorders. However, there is still no effective therapy for refractory epilepsy patients suffering from persistent mental disorders. OBJECTIVE: To explore the therapeutic effects of stereotactie multi-element localization and multi-target radiofrequency ablation on patients with refractory primary epilepsy and mental disorders. DESIGN: A retrospective case analysis. SETTING: Department of Neurosurgery, the 454 Hospital of Chinese PLA. PARTICIPANTS: Between June and November 2004, 13 patients with refractory primary epilepsy complicated by persistent mental disorders were admitted to the Department of Neurosurgery, the 454 Hospital of Chinese PLA. The patient group consisted of nine males and four females, with an average age of 25 years (range 18-39 years), and a course of disease ranging 3-11 years. Diagnosis of mental disorders was in accordance with Chinese Classification of Mental Disorders. Written informed consent was obtained from all patients and their families, and the treatment protocol was approved by the Ethics Committee of the Hospital. METHODS: Under venous inhalation anesthesia, the disease targets, including bilateral corpus callosum, bilateral amygdala, and bilateral medial septal area, as well as unilateral Forel-H area, were coagulated by RFG-3CF radiofrequency thermocoagulation at 75-80 ℃ for 60-70 seconds. During thermocoagulation, the targets were identified using deep-brain microelectrodes and localized according to electrophysiology and electric resistance values. MAIN OUTCOME MEASURES: One year post-surgery, epileptic seizures were assessed on the basis of the Tan classification, and psychogenic (non-epileptic) seizures were evaluated using a 5-grade system. RESULTS: All enrolled 13 epileptic patients were included in the final analysis. The results of follow-up evaluations demonstrated that epilepsy was

    Full Text Available Abstract Background National malaria control programmes must deal with the complex process of changing national malaria treatment guidelines, often without guidance on the process of change. Selecting a replacement drug is only one issue in this process. There is a paucity of literature describing successful malaria treatment policy changes to help guide control programs through this process. Objectives To understand the wider context in which national malaria treatment guidelines were formulated in a specific country (Peru. Methods Using qualitative methods (individual and focus group interviews, stakeholder analysis and a review of documents, a retrospective analysis of the process of change in Peru's anti-malarial treatment policy from the early 1990's to 2003 was completed. Results The decision to change Peru's policies resulted from increasing levels of anti-malarial drug resistance, as well as complaints from providers that the drugs were no longer working. The context of the change occurred in a time in which Peru was changing national governments, which created extreme challenges in moving the change process forward. Peru utilized a number of key strategies successfully to ensure that policy change would occur. This included a having the process directed by a group who shared a common interest in malaria and who had long-established social and professional networks among themselves, b engaging in collaborative teamwork among nationals and between nationals and international collaborators, c respect for and inclusion of district-level staff in all phases of the process, d reliance on high levels of technical and scientific knowledge, e use of standardized protocols to collect data, and f transparency. Conclusion Although not perfectly or fully implemented by 2003, the change in malaria treatment policy in Peru occurred very quickly, as compared to other countries. They identified a problem, collected the data necessary to justify the

    Objectives To analyze the clinical characteristics of 216 patients with non-ST segment elevation myocardial infarc-tion (NSTEMI). Methods A retrospective analysis was used. Two hundred and sixteen NSTEMI patients were divid-ed into two groups: ①according to the age: age 178 μmol. L-1 group. Seven hundred and eighty six acute myocardial infarction (AMI) patients during the same period were divided into ST seg-ment elevation myocardial infarction (STEMI) group and NSTEMI group. Clinical characteristics of the patients in th e two groups were compared. Results ① The number of NSTEMI patients in age ≥65 years group is significantly grea-ter than that in age 178 μmol· L-1) and triple ves-sel disease. Fewer patients in this group received coronary artery angiography (CAG), percutaneous coronary interven-tion (PCI) and coronary artery bypass graft (CABG). More number of deaths in this group compared with the age 4 group is significantly greater than that in TIMI score 4 group comparing with TIMI score ≤4 group. ③ Obviously, more number of elderly patients, non-insulin dependant diabetes mellitus (NIDDM), patients with cardiac troponin T (CTnT) >3.0 ng · L-1 and deaths occurred in sCr > 178 μmol · L-1 group. @ STEMI and NSTEMI patients were compared in same time frame as follows: fewer NSTEMI patients and more elderly patients had no chest pain, NID-DM, hypertension, dyslipidemia, left main coronary artery (LMCA) disease while CTnT ≥3.0 ng· ml-1; fewer pa- tients with aneurysm (30 days) underwent CAG, PCI and CABG treatment. However, there were no significant differ-ences in smokers, patients with less than 50% stenosis in any vessel, 1 -3 vessel disease, acute left ventricle heart fail-ure, cardiogenic shock, serious arrhythmia and deaths. ⑤ The multivariate logistic regression analysis showed that death in NSTEMI was directly influenced by malignant arrhythmias with age ≥ 70 years. Conclusions Patients with NSTEMI were older, had more risk factors

    BACKGROUND: Microvascular decompression has become a well-accepted, safe method in the treatment of hemifacial spasms. However, postoperative complications exist and influence the prognosis of the disease.OBJECTIVE: This study aimed to analyze, by case review, the characteristics and regularity of microvascular decompression complications in the treatment of hemifacial spasm. DESIGN: Retrospective analysis.SETTING: Beijing General Group Hospital of the Chinese People's Armed Police Forces.PARTICIPANTS: A total of 156 patients with hemifacial spasm were admitted to the Department of Neurosurgery, Beijing General Group Hospital of the Chinese People's Armed Police Forces from June 2004 to June 2006 and recruited for this study. The patients, 57 males and 99 females, averaged 46 years of age (range 17-68-years old). All suffered from facial innervated muscular paroxysmal and recurrent contraction, which could not be controlled by consciousness. Electromyogram demonstrated waves of fibrillation and fasciculation. Prior to admission, all patients had received other treatments. Written informed consents for treatment were obtained from all patients. This protocol was approved by the Hospital’s Ethics Committee. METHODS: After anesthesia, a cranial bone pore was drilled below the connection of the lateral sinus and sigmoid sinus. Dura mater was dissected at the "⊥" shape and held in the air. Under microscopy, the flocculus cerebelli was lifted slightly up for convenient observation of the cerebellopontine angle. The mucous membrane was sharply separated. Corresponding vessels were identified at the root of the facial nerves and subsequently liberated and disassociated from the root exit zone. Suitably sized Teflon cotton was placed between the corresponding vessels and brain stem.MAIN OUTCOME MEASURES: Complications of microvascular decompression.RESULTS: All 156 patients participated in the final analysis. ① Postoperatively, 66 (42%) patients presented with obvious

    Purpose: While several studies have investigated the tradeoffs between radiation dose and image quality (noise) in CT imaging, the purpose of this study was to take this analysis a step further by investigating the tradeoffs between patient radiation dose (including organ dose) and diagnostic accuracy in diagnosis of appendicitis using CT. Methods: This study was IRB approved and utilized data from 20 patients who underwent clinical CT exams for indications of appendicitis. Medical record review established true diagnosis of appendicitis, with 10 positives and 10 negatives. A validated software tool used raw projection data from each scan to create simulated images at lower dose levels (70%, 50%, 30%, 20% of original). An observer study was performed with 6 radiologists reviewing each case at each dose level in random order over several sessions. Readers assessed image quality and provided confidence in their diagnosis of appendicitis, each on a 5 point scale. Liver doses at each case and each dose level were estimated using Monte Carlo simulation based methods. Results: Overall diagnostic accuracy varies across dose levels: 92%, 93%, 91%, 90% and 90% across the 100%, 70%, 50%, 30% and 20% dose levels respectively. And it is 93%, 95%, 88%, 90% and 90% across the 13.5-22mGy, 9.6-13.5mGy, 6.4-9.6mGy, 4-6.4mGy, and 2-4mGy liver dose ranges respectively. Only 4 out of 600 observations were rated "unacceptable" for image quality. Conclusion: The results from this pilot study indicate that the diagnostic accuracy does not change dramatically even at significantly reduced radiation dose.

    Aim The use of a minimally invasive approach to treat appendicitis has yet to be universally accepted. The objective of this study was to examine recent trends in Ireland in the surgical management of acute appendicitis. Method Data were obtained from the Irish Hospital In-Patient Enquiry system for patients discharged with a diagnosis of appendicitis between 1999 and 2007. An anonymous postal survey was sent to all general surgeons of consultant and registrar level in Ireland to assess current attitudes to the use of laparoscopic appendectomy. Results The use of laparoscopic appendectomy increased throughout the study and was the most common approach for appendectomy in 2007. Multivariate analysis revealed age under 50 years (OR = 1.51), female sex (OR = 2.84) and residence in high-density population areas (OR = 4.15) as predictive factors for undergoing laparoscopic appendectomy in the most recent year of the study. While 97% of surgeons reported current use of laparoscopy in patients with acute right iliac fossa pain, in most cases it was selective. Surgeons in university teaching hospitals (42 of 77; 55%) were more likely to report using laparoscopic appendectomy for all cases of appendicitis than those in regional (six of 23; 26%) or general (13 of 53; 25%) hospitals (P = 0.048). Conclusion This study has demonstrated a significant increase in laparoscopic appendectomy, yet a variety of patient and surgeon factors contribute to the choice of procedure. Differences in the perception of benefit of the laparoscopic approach amongst surgeons appears to be an important factor in determining the operative approach for appendectomy.

    Solitary cecum diverticulum is a benign formation, but it can be complicated with inflammation, perforation and bleeding. Cecum diverticulitis (CD) is the most common complication of caecal diverticulum and it has the highest incidence among Asians, but it is a rare condition in the western world. The incidence of colonic diverticular disease can vary according to national origin, cultural structure and nutritional habits. CD is not common in our country, but it is an important situation because of its clinical similarity with the commonly seen acute right side abdominal diseases like acute appendicitis. Preoperative diagnosis is difficult, and hence, the actual frequency is not known. The treatment of CD can vary from medical therapy to right hemi colectomy. In this study, we presented ten CD cases on whom surgical resection was performed in our surgery unit during the last 8 years. Our purpose was to increase the awareness of surgeons about this situation, and so, make them pay attention for not having their first experience in the operating room.

    Full Text Available OBJECTIVE: Sporadic Creutzfeldt-Jakob disease (sCJD is a fatal and transmissible neurodegenerative disorder. However, no studies have reported Chinese specific characteristics of sCJD. We aimed to identify differences in sCJD between Chinese patients and patients from other countries. METHODS: The data from 57 Chinese sCJD patients were retrospectively analyzed, including demographic data, clinical manifestations, laboratory examinations, electroencephalograms (EEGs, diffusion-weighted imaging (DWI scans, positron emission tomography (PET scans, and pathological results. RESULT: The disease was pathologically confirmed in 11 patients. 39 cases were diagnosed as probable sCJD, and 7 were possible. Of the total cases, 33 were male, and 24 were female. The onset age ranged from 36 to 75 years (mean: 55.5, median: 57. Disease onset before the age of 60 occurred in 57.9% of patients. The disease duration from onset to death ranged 5-22 months (mean: 11.6, median: 11, and 51.9% of patients died 7 to 12 months after disease onset. The majority of patients presented with sub-acute onset with progressive dementia. 3 of the 9 patients who took 14-3-3 protein analysis had positive results (33.3%. The sensitivity of EEG was 79.6% (43/54. For DWI and PET examinations, the sensitivities were 94% (47/50 and 94.1% (16/17, respectively. In seven patients who did not show typical hyper-intensities on the first DWI examination, abnormalities of hypo-metabolism in the cerebral cortex were clearly detected by PET. In 13 out of the 17 patients, PET detected extra abnormal regions in addition to the hyper-intense areas observed in DWI. CONCLUSION: This is the first study to indicate that Chinese sCJD patients have a much earlier onset age and a longer disease duration than other populations, which is most likely related to racial differences. The longer disease duration may also be a probable characteristic of Asian populations. PET had high sensitivity for the

    The Braden Scale is the most widely used pressure ulcer risk assessment in the world, but the currently used 5 risk classification groups do not accurately discriminate among their risk categories. To optimize risk classification based on Braden Scale scores, a retrospective analysis of all consecutively admitted patients in an acute care facility who were at risk for pressure ulcer development was performed between January 2013 and December 2013. Predicted pressure ulcer incidence first was calculated by logistic regression model based on original Braden score. Risk classification then was modified based on the predicted pressure ulcer incidence and compared between different risk categories in the modified (3-group) classification and the traditional (5-group) classification using chi-square test. Two thousand, six hundred, twenty-five (2,625) patients (mean age 59.8 ± 16.5, range 1 month to 98 years, 1,601 of whom were men) were included in the study; 81 patients (3.1%) developed a pressure ulcer. The predicted pressure ulcer incidence ranged from 0.1% to 49.7%. When the predicted pressure ulcer incidence was greater than 10.0% (high risk), the corresponding Braden scores were less than 11; when the predicted incidence ranged from 1.0% to 10.0% (moderate risk), the corresponding Braden scores ranged from 12 to 16; and when the predicted incidence was less than 1.0% (mild risk), the corresponding Braden scores were greater than 17. In the modified classification, observed pressure ulcer incidence was significantly different between each of the 3 risk categories (P less than 0.05). However, in the traditional classification, the observed incidence was not significantly different between the high-risk category and moderate-risk category (P less than 0.05) and between the mild-risk category and no-risk category (P less than 0.05). If future studies confirm the validity of these findings, pressure ulcer prevention protocols of care based on Braden Scale scores can

    AIM: To evaluate the efficacy of thalidomide in combination with other therapies to treat patients with advanced hepatocellular carcinoma (HCC). METHODS: We performed a retrospective analysis of all patients with HCC who were treated with thalidomide for at least two months. The medical records of patients with HCC who were treated at our institution between April 2003 and March 2008 were reviewed. Image studies performed before and after treatment, tumor response, overall survival, and the decrease in α-fetoprotein (AFP) levels were evaluated. RESULTS: A total of 53 patients with HCC received either 100 or 200 mg/d of thalidomide. The patient population consisted of 9 women and 44 men with a median age of 61 years. Thirty patients (56.6%) were classified as Child-Pugh A, and 12 patients (22.6%) were classified as Child-Pugh B. Twenty-six patients had portal vein thrombosis (49.1%), and 25 patients had extrahepatic metastasis (47.1%). The median duration of thalidomide treatment was 6.0 mo. Six of the 53 patients achieved a confirmed response (11.3%), one achieved a complete response (1.9%) and 5 achieved a partial response (9.4%). The disease control rate (CR+PR+SD) was 28.3% (95% CI:17.8-42.4), and the median overall survival rate was 10.5 mo. The 1-and 2-year survival rates were 45% and 20%, respectively. Only one complete response patient showed an improved overall survival rate of 66.8 mo. Sixteen patients (30.2%) showed more than a 50% decrease in their serum AFP levels from baseline, indicating a better response rate (31.3%), disease control rate (43.8%), and overall survival time (20.7 mo). The therapy was well tolerated, and no significant toxicities were observed. CONCLUSION: Thalidomide was found to be safe for advanced HCC patients, demonstrating anti-tumor activity including response, survival, and AFP decreases of greater than 50% from baseline.

    Background: Intracranial abscess collections, though uncommon, are dreaded complications of head trauma, neurosurgical operations, meningitis, and otogenic, mastoid, and paranasal air sinus infections. Combining surgical evacuation with the appropriate antibiotic therapy is the effective treatment for intracranial abscesses. However, literature on surgical treatment is replete with several procedures which, on their own, may not Objectives: To determine the epidemiology and outcomes (of various treatment modalities) of intracranial abscesses in our institution, a major referral center for neurosurgical conditions in the midwestern region of Nigeria. Materials and Methods: This is a retrospective analysis of demographic data as well as indications, treatment modalities, and outcomes of various surgical procedures for evacuation of intracranial abscesses between September 2006 and December 2011. Results: We carried out 40 procedures in 32 (23 male and 9 female) patients with various intracranial abscesses. These represented approximately 5.6% of all operative neurosurgical procedures in our unit since inception. Most abscesses [16, i.e. 50%] occurred in the second decade. In the first decade, there were 7 (22%), and after the age of 30 years, there were 4 (12.5%). The most susceptible single year of life was infancy with 4 (12.5%) cases of intracranial abscesses. None of the infants had features of congenital heart disease. The predisposing factors were mostly otolaryngologic (9) or posttraumatic (6). Most abscesses (41%) were located in the frontal region, and intraparenchymal (i.e. intracerebral or intracerebellar) (50%) lesions were commoner than extradural, subdural, or intraventricular lesions. The commonest procedure performed (50%) was burr hole evacuation. Four patients (12.5% of cases) died. Prognosis appears to worsen with meningitis as the predisposing infection, ventriculitis, multiple abscesses especially in infants, and immunosuppression. Conclusion

    This study aims to document the imaging and pathology findings in non-fecalith-induced appendicitis. We reviewed the imaging and pathologic findings in 40 patients with histologically proven purulent appendicitis seen over a 2-year period. Findings documented were (1) total appendiceal involvement, (2) predominant appendiceal tip involvement, (3) presence of a fecalith, and (4) presence of lymphoid hyperplasia. There were a total of 40 patients, 28 males and 12 females. The age range was 2-18 years with a mean of 11.5 years. Twenty-two (55 %) patients demonstrated classic purulent appendicitis of the whole appendix, 20 (91 %) of these appendices had a fecalith. Eighteen (45 %) patients demonstrated purulent appendicitis confined to or predominately involving the tip of the appendix, and all 18 (100 %) patients demonstrated marked lymphoid hyperplasia. Only two (11 %) of these appendices had a fecalith. Overall, a fecalith was found in only 55 % of our cases, while 45 % demonstrated no fecalith, but rather marked lymphoid hyperplasia. Lymphoid hyperplasia appeared to be the underlying predisposing cause of purulent appendicitis in these cases.

    Sickle cell disease (SCD), one of the most common genetic disorders worldwide, is characterized by hemolytic anemia and tissue damage from the rigid red blood cells. Although hydroxyurea and transfusion therapy are administered to treat the accompanying tissue injury, whether either one prolongs the lifespan of patients with SCD is unknown. SCD-related mortality data are available, but there are few studies on mortality-related factors based on evaluations of surviving patients. In addition, ethnic variability in patient registries has complicated detailed analyses. The aim of this study was to investigate mortality and mortality-related factors among an ethnically homogeneous population of patients with SCD. The 735 patients (102 children and 633 adults) included in this retrospective cohort study were of Eti-Turk origin and selected from 1367 patients seen at 5 regional hospitals. A central population management system was used to control for records of patient mortality. Data reliability was checked by a data supervision group. Mortality-related factors and predictors were identified in univariate and multivariate analyses using a Cox regression model with stepwise forward selection. The study group included patients with homozygous hemoglobin S (Hgb S) disease (67 %), Hb S-β(0) thalassemia (17 %), Hgb S-β(+) thalassemia (15 %), and Hb S-α thalassemia (1 %). They were followed for a median of 66 ± 44 (3-148) months. Overall mortality at 5 years was 6.1 %. Of the 45 patients who died, 44 (6 %) were adults and 1 (0.1 %) was a child. The mean age at death was 34.1 ± 10 (18-54) years for males, 40.1 ± 15 (17-64) years for females, and 36.6 ± 13 (17-64) years overall. Hydroxyurea was found to have a notable positive effect on mortality (p = 0.009). Mortality was also significantly related to hypertension and renal damage in a univariate analysis (p = 0.015 and p = 0.000, respectively). Acute chest syndrome

    2006-01-01

    Full Text Available Situs inversus is often detected incidentally in adults during imaging for a acute surgical emergency. We present a case of acute appendicitis in an adult who was previously unaware about his situs anomaly. A laparoscopic approach is helpful to deal with this condition. A 40 year old man was admitted with history of acute left lower abdominal pain, with uncontrolled diabetic keto-acidosis. Clinically, he was diagnosed as acute diverticulitis with localized peritonitis. Subsequent imaging studies and laparoscopy confirmed the diagnosis of situs inversus and acute left- sided appendicitis. He successfully underwent laparoscopic appendectomy. His postoperative recovery was uneventful. Although technically more challenging because of the reverse laparoscopic view of the anatomy, the laparoscopic diagnosis and management of acute appendicitis is indicated in situs inversus.

    In order to assess the CT diagnosis of suspected acute appendicitis, we performed abdominal contrasted CT measurements in 77 patients from 20 to 86 years old, and of 50 men and 27 women from June 1993 to June 1996. The surgical findings were compared with the preoperative CT findings. By the preoperative CT imaging, we can know the degree and the position of inflammation in appendix vermiformis and the degree and the spread of periappendicular inflammation in the case of appendicitis, and can make a differential diagnosis of diverticulitis or gynecological diseases from appendicitis. It is important to make a preoperative diagnosis by the objectively excellent abdominal CT imaging and to avoid unnecessary surgery. (K.H.)

    Appendicitis in the neonatal period is extremely rare. Its low incidence together with non-specific clinical symptoms often mean the diagnosis is delayed, leading to increased rates of peritonitis and mortality. We report the case of a 33-week premature infant, small for gestational age (1180 g at birth), clinically stable and receiving exclusive enteral feeding, who presented clinical manifestations of necrotizing enterocolitis at 14 days of life. Acute phase reactants were elevated and abdominal radiography showed pneumoperitoneum. Laparotomy revealed acute perforated appendicitis without intestinal involvement and purulent fluid in the peritoneum, for which appendectomy was performed. Neonatal acute appendicitis should be considered in the differential diagnosis of abdominal sepsis since early diagnosis and treatment significantly reduce associated morbidity and mortality.

    Acute appendicitis is a common cause for pediatric surgery, with an increasing incidence as this population ages. Pseudomembranous colitis (PMC) from Clostridum difficle is being seen more frequently in pediatric patients, especially after treatment with antibiotics and in those with Hirschsprung's disease. Only three prior cases of appendicitis associated with PMC have been described in the literature, and all of them occurred in adult patients. Here, we describe the first documented pediatric case: a 16-year-old female who developed acute appendicitis while concomitantly being treated for suspected pseudomembranous colitis. We concur with previous authors that there may be an association between these two pathologies; furthermore, this association may not always be clinically apparent and may be both under-diagnosed and under-reported.

    Three imaging modalities are available for the diagnosis of acute appendicitis: ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Transabdominal ultrasound should be the first-line imaging test. Abdominal CT is superior to US and is required immediately in patients with atypical clinical presentation of appendicitis and suspected perforation. However, low-dose unenhanced CT is equal to standard-dose CT with intravenous contrast agents in the detection of five signs of acute appendicitis (thickened appendiceal wall more than 2 mm, cross-sectional diameter greater than 6 mm, periappendicitis, abscess, and appendicolith). MRI is necessary in pregnant women and young adults. This review illustrates the principles of state-of-the-art imaging techniques and their clinical relevance. (orig.)

    Full Text Available Introduction: Acute appendiceal diverticulitis is an unusual cause of acute abdomen, considered clinically indistinguishable from acute appendicitis. Material and methods: In a historic cohort study with 27 cases of appendiceal diverticulitis and 54 cases of acute appendicitis, we compared clinical characteristics, diagnostic tests and pathology findings of the two processes. Results: Mean age at presentation was lower in acute appendicitis (37.24 ± 19.98 vs. 54.81 ± 17.55 years, p < 0.001, with significant differences between men (33.33 ± 15.89 vs. 57 ± 18.02 years, p < 0.001 but not between women (41.76 ± 24.87 vs. 50.44 ± 16.69 years, p = 0.34. In the diverticulitis group, 48.15 % had leukocytosis vs. 81.48 % in the appendicitis group (p = 0.02; there was no difference in leukocyte count (13770.37 ± 4382.55 vs. 14279.63 ± 4268.59, p = 0.61. Patients with appendiceal diverticulitis had a higher incidence of appendiceal mucocele (p = 0.01 and a lower proportion of appendiceal gangrene (p = 0.03. There were no differences in appendiceal perforation or ulceration. Symptom duration before emergency department attendance (71.61 ± 85.25 hours vs. 36.84 ± 33.59 hours; Z = -3.1 p = 0.002, duration of surgery (85 ± 40 minutes vs. 60 ± 21 minutes, Z = -3.2, p = 0.001 and the presence of appendicular plastron was higher in patients with diverticulitis vs. appendicitis (8 vs. 5 patients (p = 0.01, Odds ratio 2.2. Conclusions: Appendiceal diverticulitis presents a series of clinical, epidemiological and pathological differences with respect to acute appendicitis. The former shows a more indolent course with delayed diagnosis.

    Full Text Available Abstract Background Many studies have been carried out that focus on mental patients' access to care for their mental illness, but very few pay attention on these same patients' access to care for their physical diseases. Acute appendicitis is a common surgical emergency. Our population-based study was to test for any possible association between mental illness and perforated appendicitis. We hypothesized that there are significant disparities in access to timely surgical care between appendicitis patients with and without mental illness, and more specifically, between patients with schizophrenia and those with another major mental illness. Methods Using the National Health Insurance (NHI hospital-discharge data, we compared the likelihood of perforated appendix among 97,589 adults aged 15 and over who were hospitalized for acute appendicitis in Taiwan between the years 1997 to 2001. Among all the patients admitted for appendicitis, the outcome measure was the odds of appendiceal rupture vs. appendicitis that did not result in a ruptured appendix. Results After adjusting for age, gender, ethnicity, socioeconomic status (SES and hospital characteristics, the presence of schizophrenia was associated with a 2.83 times higher risk of having a ruptured appendix (odds ratio [OR], 2.83; 95% confidence interval [CI], 2.20–3.64. However, the presence of affective psychoses (OR, 1.15; 95% CI: 0.77–1.73 or other mental disorders (OR, 1.58; 95% CI: 0.89–2.81 was not a significant predictor for a ruptured appendix. Conclusion These findings suggest that given the fact that the NHI program reduces financial barriers to care for mentally ill patients, they are still at a disadvantage for obtaining timely treatment for their physical diseases. Of patients with a major mental illness, schizophrenic patients may be the most vulnerable ones for obtaining timely surgical care.

    Fourteen patients who presented to the University Hospital of Kuala Lumpur between June 1981 and June 1991 were reviewed retrospectively. Nasal septal abscesses are uncommon and therefore there are limited reports in the medical literature. Early diagnosis and immediate therapy is mandatory to avoid cosmetic nasal deformity or intracranial infection. Two out of the fourteen patients developed saddle nose deformity and septal perforation because of delay in treatment, the cases were misdiagnosed by non-otolaryngologist as turbinates swelling. The leading cause of nasal septal abscess was non-surgical trauma which accounted for about 85.7%. The commonest pathogenic organism isolated from the pus of nasal septal abscess was Staphylococcus aureus.

    2003-12-01

    Full Text Available A decision support system for production planning in a brewing company was developed to assist with the planning of brewing, packaging and distribution of beer and to minimise production costs. Having been in operation for some time, the system has changed and adapted in a very dynamic environment. The system's present form and current use are discussed. Initial management approval for system development was based on faith rather than proper cost-benefit and value analyses. This paper aims at retrospectively highlighting these values and benefits with regard to supporting decision-making in the company.

    Appendicitis is common in children. Early diagnosis depends on recognition of characteristic signs and symptoms: right lower quadrant or periumbilical pain, localized tenderness, fever, and leukocytosis. Because these classic features may be difficult to elicit or masked by other complaints, the incidence of perforative appendicitis in children is high. This paper reviews the imaging sequelae with emphasis on CT and sonography findings. Areas of focus include abdominopelvic abscess, peritonitis, pyelephlebitis, pyelethrombosis, and hepatic abscess. Secondary involvement of the urinary and gastrointestinal tracts is also discussed. (orig.)

    Full Text Available Abstract Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection. We describe four cases that presented with symptoms suggestive of appendicitis, but were found at operation to have an inflamed solitary diverticulum.

    Acute myelogenous leukemia (AML) can involve the gastrointestinal tract but rarely involves the appendix.We report a male patient who had 1 year partial remission from AML and who presented with apparent acute appendicitis as the initial manifestation of leukemia relapse. Pathological findings of the appendix revealed transmural infiltrates of myeloblasts, whichindicated a diagnosis of leukemia. Unfortunately, the patient died from progression of the disease on the 19th d after admission. Although leukemic cell infiltration of the appendix is uncommon, patients with leukemia relapse can present with symptoms mimicking acute appendicitis.

    Full Text Available Leukemic and lymphomatous infiltration of the appendix is a rare complication. We present the case of a 31-year-old male with acute promyelocytic leukemia who developed acute abdomen on day 11 of induction chemotherapy with idarubicin and cytarabine. After appropriate work-up, a clinical diagnosis of acute appendicitis was made. Despite severe pancytopenia, he successfully underwent laparoscopic appendectomy. The final pathology revealed leukemic infiltration of the appendix. It is hypothesized that the leukemic infiltration may play a role in the development of acute appendicitis. Further, this case demonstrates the need to maintain a high index of suspicion and prompt surgical intervention for surgical pathologies in neutropenic patients.

    The author evaluates the case-history of 51 children with perforated appendicitis treated during 1984-1995 at the First Surgical Clinic of the Faculty Hospital Olomouc. The purpose was to find an answer to the problem why in these children the diagnosis was delayed and whose was the fault of the substantial deterioration of the health status. In the evaluation four groups of causal responsibility are differentiated: a very rapid development of appendicitis-parents, arriving late in the surgery-paediatricians-surgeons. The authors discuss circumstances associated with the diagnostic error and delay.

    The clinical diagnosis of classic Crohn's disease (CD)of the small bowel is based on a typical history, tender right lower quadrant fullness or mass, and characteristic radiographic findings of the terminal ileum. Appendicitis may as well present with chronic or recurrent symptoms and this presentation may be confused with CD. We herein describe the case of a young teenage girl with a presumptive diagnosis of CD, who was ultimately diagnosed as having chronic nongranulomatous appendicitis. The literature on the subject is reviewed.

    2010-01-01

    INTRODUCTION: Residual appendicitis involving the stump of the appendix has been well described in the literature in the past. CASE REPORT: We report the case of a 43 year old male with acute onset of abdominal pain who had undergone an appendicectomy ten years previously. Ultrasound revealed the presence of an inflamed tubular structure. Subsequent laparotomy and histology confirmed that this structure was an inflamed residual appendiceal tip. CONCLUSION: Residual tip appendicitis has not been reported in the literature previously and should be considered in the differential diagnosis of localised peritonitis in a patient with a history of a previous open appendicectomy.

    AIM: To evaluate the maximal-outer-diameter (MOD) and the maximal-mural-thickness (MMT) of the appendix in children with acute appendicitis and to determine their optimal cut-off values to diagnose acute appendicitis. METHODS: In total, 164 appendixes from 160 children between 1 and 17 years old (84 males, 76 females; mean age, 7.38 years) were examined by high-resolution abdominal ultrasound for acute abdominal pain and the suspicion of acute appendicitis. We measured the MOD and the MMT at the thickest point of the appendix. Patients were categorized into two groups according to their medical records: patients who had surgery (surgical appendix group) and patients who did not have surgery (non-surgical appendix group). Data were analyzed by MedCalc v.9.3. The rank sum test (Mann-Whitney test) was used to evaluate the difference in the MOD and the MMT between the two groups. ROC curve analysis was used to determine the optimal cut-off value of the MOD and the MMT on diagnosis of acute appendicitis.RESULTS: There were 121 appendixes (73.8%) in the non-surgical appendix group and 43 appendixes (26.2%) in the surgical appendix group. The median 26.2%) in the surgical appendix group. The median MOD differed significantly between the two groups (0.37 cm vs 0.76 cm, P 0.57 cm (sensitivity 95.4%, specificity 93.4%) and > 0.22 cm (sensitivity 90.7%, specificity 79.3%), respectively. CONCLUSION: The MOD and the MMT are reliable criteria to diagnose acute appendicitis in children. An MOD > 0.57 cm and an MMT > 0.22 cm are the optimal criteria.

    Full Text Available Abstract Backround The emergence of Mycobacterium tuberculosis strains resistant to antituberculosis agents has recently received increased attention owing largely to the dramatic outbreaks of multi drug resistance tuberculosis (MDR-TB. Methods Patients residing in Zonguldak and Kayseri provinces of Turkey with, pulmonary tuberculosis diagnosed between 1972 and 1999 were retrospectively identified. Drug susceptibility tests had been performed for isoniazid (INH, rifampin (RIF, streptomycin (SM, ethambutol (EMB and thiacetasone (TH after isolation by using the resistance proportion method. Results Total 3718 patients were retrospectively studied. In 1972–1981, resistance rates for to SM and INH were found to be 14.8% and 9.8% respectively (n: 2172. In 1982–1991 period, resistance rates for INH, SM, RIF, EMB and TH were 14.2%, 14.4%, 10.5%, 2.7% and 2.9% (n: 683, while in 1992–1999 period 14.4%, 21.1%, 10.6%, 2.4% and 3.7% respectively (n: 863. Resistance rates were highest for SM and INH in three periods. MDR-TB patients constituted 7.3% and 6.6% of 1982–1991 and 1992–1999 periods (p > 0.05. Conclusion This study demonstrates the importance of resistance rates for TB. Continued surveillance and immediate therapeutic decisions should be undertaken in order to prevent the dissemination of such resistant strains.

  16. Schwannomas in the head and neck: retrospective analysis of 21 patients and review of the literature

    Directory of Open Access Journals (Sweden)

    Erwin Langner

    Full Text Available CONTEXT AND OBJECTIVE: Schwannomas are benign neoplasms of the peripheral nerves originating in the Schwann cells. According to their cellularity, they can be subdivided into Antoni A or Antoni B types. They are rare and usually solitary, with clearly delimited capsules. They occur in the head and neck region in only 25% of the cases, and may be associated with Von Recklinghausen's disease. The present study retrospectively analyzed some data on this disease in the head and neck region and reviewed the literature on the subject. DESIGN AND SETTING: Retrospective study at Head and Neck Service, Universidade Estadual de Campinas. METHODS: Data on 21 patients between 1980 and 2003 were reviewed. The sites of cervical schwannomas and the intraoperative, histopathological and postoperative clinical status of these cases were studied. Diagnostic methods, type of surgery and association with neurofibromatosis were evaluated. RESULTS: The patients' ages ranged from 16 to 72 years. Four patients had a positive past history of type I neurofibromatosis or Von Recklinghausen's disease. The nerves affected included the brachial and cervical plexuses, vagus nerve, sympathetic chain and lingual or recurrent laryngeal nerve. The nerve of origin was not identified in six cases. Tumor enucleation was performed in 16 patients; the other five required more extensive surgery. CONCLUSION: Schwannomas and neurofibromas both derive from Schwann cells, but are different entities. They are solitary lesions, except in Von Recklinghausen's disease. They are generally benign, and rarely recur. The recommended surgical treatment is tumor enucleation.

    Some neuroprotective agents have shown benefits in animal models, but disappointing results in humans. Citicoline is used in several countries as coadjuvant treatment in acute ischemic stroke (AIS) patients; however, there are no retrospective postmarketing surveillances on the experience of citicoline in Mexico. The aim of this study was to evaluate the correlation between citicoline exposure and functional outcome at discharge and at 30 and 90 days post-stroke, in a retrospective case-control design on systematic descriptive databases from three referral hospitals. Clinical records of 173 consecutively registered patients were analyzed, 86 of whom were treated with citicoline within the first 48 h after AIS and the remaining 87 were untreated, randomly selected controls matched for age (+/- 5 years), gender and NIHSS (+/- 1 point) at hospital admission. Pretreatment conditions were similar between groups. Compared with controls, exposure to citicoline was associated with a significantly lower 30-day mean and median modified Rankin score (in both, P citicoline was independently associated with a lower 90-day mortality risk (P = 0.047) and with fewer in-hospital complications (mainly infections and sepsis, P = 0.001). In this observational study, citicoline use was associated with a better functional status and lower rates of short-term mortality, possibly due to fewer in-hospital systemic complications. The putative benefits should be interpreted as clinical associations, since this is not a randomized, controlled clinical trial.

    2015-06-15

    Purpose: IMRT QA using planar dose measurements is still a widely used method for checking the accuracy of treatment plans. A pass/fail judgment is made using gamma analysis based on a single endpoint. Using more stringent criteria is a way to increase the sensitivity to planning and delivery errors. Before such implementation, it is necessary to understand how the sensitivity to different gamma criteria settings affects gamma passing rates (GPR). Methods: 752 IMRT QA measurements were re-analyzed with varying distance to agreement (DTA) and dose difference (DD) percentages using a Matlab program. Other quantifying information such as the mean dose difference in the treatment target (defined as points that are greater than 80% of maximal dose) were stored in a relational database for retrospective analysis. Results: The average and standard deviation of GPR (%) fell from 99.84 ± (0.43) to 89.61 ± (6.08) when restricting DD from 5 − 1% respectively, as compared to a drop from 99.15 ± (1.19) to 95.00 ± (4.43), when restricting the DTA from 5 − 1 mm respectively. The mean dose difference (%) in the treatment target between measured and calculated dose was −1.96 ± (0. 83), −0.09 ± (0.98), and 1.44 ± (0. 86) for each of our institution’s three matched linear accelerators (LINAC 1, 2, and 3 respectively). For plans that are approximately 2.7 sigma below the mean GPR, an average of 78.4% of those plans were measured on LINAC 1 or 3, while only 48% of the total plans were run on those machines. Conclusion: The data demonstrates that when restricting gamma criterion, such as the DD, the greatest indicator of reduced GPR in our institution is which matched LINAC the plan was measured on. While small, these differences manifest themselves to levels comparable to other treatment related differences and possibly confound the gamma analysis.

    Full Text Available BACKGROUND: Early discrimination between transient and persistent par-solid ground-glass nodules (PSNs at CT is essential for patient management. The objective of our study was to retrospectively investigate the value of texture analysis in differentiating pulmonary transient and persistent PSNs in addition to clinical and CT features. METHODS: This retrospective study was performed with IRB approval and a waiver of the requirement for patients' informed consent. From January 2007 to October 2009, we identified 77 individuals (39 men and 38 women; mean age, 55 years with 86 PSNs on thin-section chest CT. Thirty-nine PSNs in 31 individuals were transient and 47 PSNs in 46 patients were persistent. The clinical, CT, and texture features of PSNs were evaluated. To investigate the additional value of texture analysis in differentiating transient from persistent PSNs, logistic regression analysis and C-statistics were performed. RESULTS: Between transient and persistent PSNs, there were significant differences in age, gender, smoking history, and eosinophil count among the clinical features. As for thin-section CT features, there were significant differences in lesion size, solid portion size, and lesion multiplicity. In terms of texture features, there were significant differences in mean attenuation, skewness of whole PSN, attenuation ratio of whole PSN to inner solid portion, and 5-, 10-, 25-, 50-percentile CT numbers of whole PSN. Multivariate analysis revealed eosinophilia, lesion size, lesion multiplicity, mean attenuation of whole PSN, skewness of whole PSN, and 5-percentile CT number were significant independent predictors of transient PSNs. (P<0.05 C-statistics revealed that texture analysis incorporating clinical and CT features (AUC, 92.9% showed significantly higher differentiating performance of transient from persistent PSNs compared with the clinical and CT features alone (AUC, 79.0%. (P =  0.004. CONCLUSION: Texture analysis of

    We wanted to determine the usefulness of the computed tomography (CT) findings for making the diagnosis between periappendiceal inflammation (PAI) with appendicitis and pelvic inflammatory disease (PID) for the women presenting with right lower quadrant pain. We retrospectively analyzed the CT findings of 83 women with right lower quadrant pain: PAI in 36 and PID in 47 patients. We reviewed the CT images, including the appendiceal diameter and the enhancing wall thickening, the cecal thickening, the location of the appendix, thickening of the right anterior renal fascia, abscess, mesenteric fatty infiltration, ascites, heterogeneous uterine enhancement and paralytic ileus. Statistical analysis was performed by using the t-test for the diameter of appendix, and the x{sup 2} test or Fisher's exact test for the CT findings. The mean diameter of the appendix was 11.0 {+-} 3.4 mm for the PAI subjects and it was 6.7 {+-} 2.0 mm for the PID subjects ({rho} < 0.0001). Wall thickening of the appendix was more commonly detected in PAI (25 subjects, 69%) than in PID (15 subjects, 32%) ({rho} = 0.0007). Thickening of the right anterior renal fascia was more commonly detected in PAI (18 subjects, 50%) than in PID (7 subjects, 15%). Cecal thickening, ascitis, heterogeneous uterine enhancement and paralytic ileus were not significantly different between PAI and PID. Abscess and mesenteric fatty infiltration were more frequently detected in the RLQ and in the abdomen or pelvic cavity in PAI and PID, respectively ({rho} < 0.05). There was no significant difference in the distribution of ascites between the diseases. The CT findings of the appendiceal diameter, enhancing wall thickening and thickening of the right anterior renal fascia are useful for making the diagnosis of PAI. The abdominal and pelvic distributions of abscess and mesenteric fatty infiltration are highly suggestive findings of PID.

    Purpose: To compare the accuracy of computed tomography (CT) analyzed by individual radiology staff members and body imaging radiologists in a non-academic teaching hospital for the diagnosis of acute appendicitis. Patients and methods: In a prospective study 199 patients with suspected acute appendicitis were examined with unenhanced CT. CT images were pre-operatively analyzed by one of the 12 members of the radiology staff. In a later stage two body imaging radiologist reassessed all CT images without knowledge of the surgical findings and without knowledge of the primary CT diagnosis. The results, independently reported, were correlated with surgical and histopathologic findings. Results: In 132 patients (66%) acute appendicitis was found at surgery, in 67 patients (34%) a normal appendix was found. The sensitivity of the primary CT analysis and of the reassessment was 76% and 88%, respectively; the specificity was 84% and 87%; the positive predictive value was 90% and 93%; the negative predictive value was 64% and 78%; and the accuracy was 78% and 87%. Conclusion: Reassessment of CT images for acute appendicitis by body imaging radiologists results in a significant improvement of sensitivity, negative predictive value and accuracy. To prevent false-negative interpretation of CT images in acute appendicitis the expertise of the attending radiologist should be considered.

    Full Text Available The incidence of malignancy in nodular goiter has been found to vary from 4% to 17%. Our aim is to determine the incidence of malignancy in nodular goiter by doing the histopathological examination of thyroidectomy specimens. MATERIALS AND METHODS: This retrospective, observational study was carried out on patients who are undergone thyroidectomy for clinically diagnosed nodular goiter in Fr . Muller Medical College Hospital during 2012 - 2014 (3 yrs. All the operated specimens were subjected to a histopathological examination to determine the incidence of malignancy. RESULTS: Among the 258 nodular goitre cases which were studied, 21 (8.1% cases contained malignant foci. Among them, papillary carcinoma was the most common type of malignancy observed. CONCLUSION: The risk of malignancy in nodular goitre should not to be underestimated. Total/ Near - total thyroidectomy is the preferred operation. All the operated specimens should be sent for histopathological examination

    Antecedent infections have been found to be the most common trigger for Guillain-Barre syndrome (GBS). In the present study, we retrospectively analyzed 36 adult patients with GBS and found that surgery, trauma and treatment with ganglioside were also common before the onset of GBS. The proportion of the axonal subtype of GBS in post-surgical/traumatic patients was higher than that in non-surgical/traumatic patients (P=0.013) in the present study. In conclusion, this study has shown that prior infection, surgery, trauma and ganglioside may be clinical contributors to the onset of GBS and raised the possibility that they may act synergistically as triggers for the development of GBS.

    Breast feeding stimulates a more tolerant lymphoid tissue at the base of the appendix and this could provide protection against acute appendicitis. Two studies reported that children and adolescents with appendicitis were less likely to have been breast fed. In a case-control study of 200 children with histologically confirmed acute appendicitis matched by 200 siblings with the same sex and difference age - up to three-year-old - we found breast feeding in at least the first two months of life and for more than four months provides protection against acute appendicitis. These findings suggesting that breast feeding may possibly give protection against the development of appendicitis.

    AIM: To retrospectively evaluate the prevalence of lymph nodes of the hepato-duodenal ligament in a group of patients with chronic liver disease of various aetiologies and to investigate what clinical, aetiological and laboratory data may lead to their appearance. MATERIALS AND METHODS: One thousand and three patients (554 men, 449 women) were studied, including 557 with chronic hepatitis and 446 with liver cirrhosis. The presence of lymph nodes near the trunk of the portal vein, hepatic artery, celiac axis, superior mesenteric vein and pancreas head was investigated using ultrasound. RESULTS: Lymph nodes were detected in 394 out of the 1003 study patients (39.3%); their number ranged from one to four, with a diameter ranging between 0.8 and 4 cm. The highest prevalence was in the subgroup of patients with primary biliary cirrhosis (87.5%), followed by patients with hepatitis C virus (HCV; 42%), patients with HCV and hepatitis B virus (HBV; 41.3%), autoimmune hepatitis (40%), and HBV alone (21.2%). In the alcoholic and idiopathic subgroups prevalence was 9.5%, while in the non-alcoholic steatohepatitis and haemochromatosis subgroups it was 0%. HCV RNA was present in 97 out of 103 lymph node-positive patients and in 141 out of 168 lymph node-negative HCV-negative patients (p<0.003). Lymphadenopathy frequency increased as the liver disease worsened ({chi}{sup 2} MH=74.3; p<0.0001). CONCLUSION: Despite the limitations of a retrospective study, our data indicate a high prevalence of lymphadenopathy in liver disease patients; ultrasound evidence of lymph nodes of the hepato-duodenal ligament in a given liver disease may most likely suggest a HCV or an autoimmune aetiology and a more severe histological picture.

    Full Text Available Aim: Infection is an important problem in intensive care units (ICU which is a complication of nutritional support. In our institution, we aimed to determine the differences in infection rates of patients who were supported with parenteral nutrition (PN and enteral + parenteral nutrition (EN+PN combination retrospectively. Material and Method: In this study, we enrolled 156 patients from January 1, 2011 to Agust 1, 2011. There were 88 patients in the parenteral nutrition group (Group 1 and 68 patients in the enteral+ parenteral nutrition group (Group 2. On all 156 patients, retrospective chart reviews were performed and biweekly culture results were recorded. Specifically, soft tissue infections, skin infections, catheter related blood stream infections, pneumonia and urinary tract infections were recorded. HI (hospital infection incidences and incidence densities were also calculated in both groups. Results: There were 16 recorded infections in 16 patients among Group 1. These were 4 cases of catheter related blood stream infections, 4 cases of pneumonia, 3 cases of urinary tract infections and 5 cases of soft tissue infections. In group 2, 8 patients showed signs of infection. These were, 4 cases catheter related blood stream infections, 2 cases of soft tissue infections and 2 cases of urinary tract infections. There were no reported pneumonia cases in group 2. Discussion: According to our results, with the exception of catheter related blood stream infections, infection numbers declined within the group of combination of enteral and parenteral nutrition group than parenteral nutrition group alone, but the results were not statistically significant. The intolerance to enteral nutrition can increase the cost of stay, mainly due to increased length of stay as a result of increased infection rates. We would recommend a combination nutrition regimen in such a similar situation, in order to decrease infection rates.

    PURPOSE: The primary objective of this study was to determine any difference in progression free survival (PFS), overall survival (OS), clinical benefit and tolerability between elderly and non-elderly patients receiving bevacizumab at recurrence for glioblastoma in a single center. PATIENTS AND METHODS: We retrospectively analyzed 32 patients with recurrent glioblastoma receiving bevacizumab (10 mg/kg every 14 days) between January 2011 and December 2013 in second line. Bevacizumab was introduced for all patients at recurrence after a treatment of first line by temozolomide. A cohort of 14 patients was older than 70 years against 18 patients were under 70 years. RESULTS: No statistically significant difference was detected in terms of PFS and OS. PFS was 2.8 months for elderly patients against 2.9 for non-elderly patients (p >0.5). OS from recurrence in elderly and non-elderly patients was respectively 4.3 and 5.5 months (p >0,5). Clinical improvement in neurological symptoms was observed in 3 of 14 elderly patients (21.1%) and 11 of 18 young patients (61.1%). A more important improvement in performance status was observed in young patients. Regarding toxicity, 3 of the 14 elderly patients experienced grade II or III hypertension. In younger patients, 5 adverse events have been observed (2 proteinuria, 1 hypertension, 1 hemorrhage and 1 anal abscess). CONCLUSION: Despite small number of patients in this retrospective study, the efficacy and safety of bevacizumab in recurrent glioblastoma appears similar in elderly and non-elderly patients. However, clinical benefit seemed to be less important in elderly patients. A prospective multicentric study integrating geriatric assessment tools and quality of life would be interesting in this patient's population.

    2016-03-01

    Full Text Available Xanthene dyes can be appended to cyclodextrins via an ester or amide bridge in order to switch the fluorescence on or off. This is made possible through the formation of nonfluorescent lactones or lactams as the fluorophore can reversibly cyclize. In this context we report a green approach for the synthesis of switchable xanthene-dye-appended cyclodextrins based on the coupling agent 4-(4,6-dimethoxy-1,3,5-triazin-2-yl-4-methylmorpholinium chloride (DMT-MM. By using 6-monoamino-β-cyclodextrin and commercially available inexpensive dyes, we prepared rhodamine- and fluorescein-appended cyclodextrins. The compounds were characterized by NMR and IR spectroscopy and MS spectrometry, their UV–vis spectra were recorded at various pH, and their purity was determined by capillary electrophoresis. Two potential models for the supramolecular assembly of the xanthene-dye-appended cyclodextrins were developed based on the set of data collected by the extensive NMR characterization.

    Acute appendicitis is one of the most common causes of acute abdominal pain. Accurate diagnosis is often hindered due to various presentations that differ from the typical signs of appendicitis, especially the position of the appendix. A delay in diagnosis or treatment may result in increased risks of complications, such as perforation, which is associated with increased morbidity and mortality rates. Necrotizing fasciitis caused by perforated appendicitis is extremely rare. We herein report a case of 50-year-old man presenting with an appendiceal abscess in local hospital. After ten days of conservative treatment with intravenous antibiotics, the patient complained about pain and swelling of the right lower limb and computed tomography (CT) demonstrated a perforated appendix and gas and fluid collection extending from his retroperitoneal cavity to the subcutaneous layer of his right loin and right lower limb. He was transferred to our hospital and was diagnosed with necrotizing fasciitis caused by perforated appendicitis. Emergency surgery including surgical debridement and appendectomy was performed. However, the patient died of severe sepsis and multiple organ failure two days after the operation. This case represents an unusual complication of a common disease and we should bear in mind that retroperitoneal inflammation and/or abscesses may cause necrotizing fasciitis through lumbar triangles.

    To evaluate whether mandatory imaging is an effective strategy in suspected appendicitis for reducing unnecessary surgery and costs. In 2010, guidelines were implemented in The Netherlands recommending the mandatory use of preoperative imaging to confirm/refute clinically suspected appendicitis. This retrospective study included 1,556 consecutive patients with clinically suspected appendicitis in 2008-2009 (756 patients/group I) and 2011-2012 (800 patients/group II). Imaging use (none/US/CT and/or MRI) was recorded. Additional parameters were: complications, medical costs, surgical and histopathological findings. The primary study endpoint was the number of unnecessary surgeries before and after guideline implementation. After clinical examination by a surgeon, 509/756 patients in group I and 540/800 patients in group II were still suspected of having appendicitis. In group I, 58.5% received preoperative imaging (42% US/12.8% CT/3.7% both), compared with 98.7% after the guidelines (61.6% US/4.4% CT/ 32.6% both). The percentage of unnecessary surgeries before the guidelines was 22.9%. After implementation, it dropped significantly to 6.2% (p<0.001). The surgical complication rate dropped from 19.9% to 14.2%. The average cost-per-patient decreased by 594 EUR from 2,482 to 1,888 EUR (CL:-1081; -143). Increased use of imaging in the diagnostic work-up of patients with clinically suspected appendicitis reduced the rate of negative appendectomies, surgical complications and costs. (orig.)

    OBJECTIVE. The purpose of this study was to determine the effect of a nominal 50% reduction in median absorbed radiation dose on sensitivity, specificity, and negative appendectomy rate of CT for acute appendicitis in children. MATERIALS AND METHODS. On the basis of a departmental practice quality improvement initiative using computer-generated gaussian noise for CT dose reduction, we applied a nominal dose reduction of 50% to abdominal CT techniques used for bowel imaging. This retrospective study consisted of 494 children who underwent a CT for suspected acute appendicitis before (n = 244; mean age, 133 months) and after (n = 250; mean age, 145 months) the nominal 50% dose reduction. Test performance characteristics of CT for acute appendicitis and impact on the negative appendectomy rate were compared for both time periods. Primary analyses were performed with histologic diagnosis as the outcome standard. Volume CT dose index and dose-length product were recorded from dose reports and size-specific dose estimates were calculated. RESULTS. The nominal 50% dose reduction resulted in an actual 39% decrease in median absorbed radiation dose. Sensitivity of CT for diagnosis of acute appendicitis was 98% (95% CI, 91-100%) versus 97% (91-100%), and specificity was 93% (88-96%) versus 94% (90-97%) before and after dose reduction, respectively. The negative appendectomy rate was 4.5% (0.8-10.25%) before dose reduction and 4.0% (0.4-7.6%) after dose reduction. CONCLUSION. The negative appendectomy rate and performance characteristics of the CT-based diagnosis of acute appendicitis were not affected by a 39% reduction in median absorbed radiation dose.

    Appendicitis and gastroesophageal reflux disease (GERD) are both prevalent diseases and might share similar pathological mechanisms. The aim of this study was to investigate the association between GERD and appendicitis using a large population-based dataset. This study used administrative claims data from the Taiwan Longitudinal Health Insurance Database 2005. We identified 7113 patients with appendicitis as cases, and 28452 matched patients without appendicitis as controls. This study revealed that GERD was found in 359 (5.05%) cases and 728 (2.56%) controls (p appendicitis were 1.96 (95% CI: 1.56~2.47), 2.36 (95% CI: 1.94~2.88), and 1.71 (95% CI: 1.31~2.22) than controls, respectively. We concluded that patients with appendicitis had higher odds of prior GERD than those without appendicitis regardless of age group.

    Purpose: The purpose of the study was to evaluate unenhanced Magnetic Resonance Imaging (MRI) for the diagnosis of appendicitis or another surgery-requiring condition in an adult population scheduled for emergency appendectomy based on a clinical diagnosis of suspected acute appendicitis. Materials and methods: The prospective study included 48 consecutive patients (29 female, 19 male, 18-70 years old, mean age = 37.1 years). MRI examination was designed to be comfortable and fast; no contrast was administered. The sequences were performed during quiet respiration. The MRI findings were reviewed by two radiologists and one surgeon independent of each other and compared with surgical and pathological records. Results: According to the surgical and histopathological findings 30 of 48 patients (63%) had acute appendicitis. Of the remaining 18 patients, 4 patients had no reasons for the clinical symptoms and 14 patients had other pathology. For the three reviewers the performance of MRI in the diagnosis of acute appendicitis showed the following sensitivity, specificity and accuracy ranges: 83-93%, 50-83% and 77-83%. Moderate ({kappa} = 0.51) and fair ({kappa} = 0.31) interobserver agreements in the MR diagnosis of acute appendicitis were found between the reviewers. Sensitivity, specificity and accuracy values for overall performance of MRI in detecting pelvic abnormalities were 100%, 75% (3 of 4 healthy patients were identified by MRI) and 98%, respectively. Conclusion: Unenhanced fast MRI is feasible as an additional fast screening before the appendectomy. It may prevent unnecessary surgeries. The fast MRI examination can be adequately performed on an MRI unit of broad range of field strengths.

    Full Text Available Background: Because of lack of good evidence supporting laparoscopic approach for complicated appendicitis, we carried out this study to evaluate efficacy of laparoscopic appendectomy (LA in management of patients with complicated appendicitis. Materials and Methods: This study was carried out in Surgical Department, Minia University, Egypt involving 214 patients underwent appendectomy for complicated appendicitis over three years. 132 patients underwent LA and remaining 82 patients underwent OA. Parameters studied included operating time, return to oral feeding, postoperative pain, wound infection, intra-abdominal abscess, duration of abdominal drainage and hospital stay. Results: There were four conversions, two due to extensive cecal adhesions and two due to friable appendix. LA took longer time to perform (p = 0.0002 but with less use of analgesics (p < 0.0001, shorter hospital stay (p < 0.0001, shorter duration of abdominal drainage (p < 0.0001 and lower incidence of wound infection (p = 0.0005. Nine patients in LA and seven patients in OA group developed intra-abdominal abscess treated successfully with sonographic guided percutaneous drainage. Postoperative ileus was recorded in two patients in LA group and three patients in OA group, chest infection in one patient in OA group, hernia in one patient in LA and fecal fistula was present in one patient in OA. Overall complications were significantly lower in laparoscopy group and managed conservatively with no mortality in either group. Conclusions: LA in complicated appendicitis is feasible and safe with lower incidence of complications than OA and should be the initial choice for all patients with complicated appendicitis.

    Full Text Available Abstract Background This retrospective survey describes types of cancers diagnosed in HIV-infected subjects in Asia, and assesses risk factors for cancer in HIV-infected subjects using contemporaneous HIV-infected controls without cancer. Methods TREAT Asia HIV Observational Database (TAHOD sites retrospectively reviewed clinic medical records to determine cancer diagnoses since 2000. For each diagnosis, the following data were recorded: date, type, stage, method of diagnosis, demographic data, medical history, and HIV-related information. For risk factor analyses, two HIV-infected control subjects without cancer diagnoses were also selected. Cancers were grouped as AIDS-defining cancers (ADCs, and non-ADCs. Non-ADCs were further categorized as being infection related (NADC-IR and unrelated (NADC-IUR. Results A total of 617 patients were included in this study: 215 cancer cases and 402 controls from 13 sites. The majority of cancer cases were male (71%. The mean age (SD for cases was 39 (10.6, 46 (11.5 and 44 (13.7 for ADCs, NADC-IURs and NADCs-IR, respectively. The majority (66% of cancers were ADCs (16% Kaposi sarcoma, 40% non-Hodgkin's lymphoma, and 9% cervical cancer. The most common NADCs were lung (6%, breast (5% and hepatocellular carcinoma and Hodgkin's lymphoma (2% each. There were also three (1.4% cases of leiomyosarcoma reported in this study. In multivariate analyses, individuals with CD4 counts above 200 cells/mm3 were approximately 80% less likely to be diagnosed with an ADC (p Conclusions The spectrum of cancer diagnoses in the Asia region currently does not appear dissimilar to that observed in non-Asian HIV populations. One interesting finding was the cases of leiomyosarcoma, a smooth-muscle tumour, usually seen in children and young adults with AIDS, yet overall quite rare. Further detailed studies are required to better describe the range of cancers in this region, and to help guide the development of screening programmes.

    To evaluate the efficacy and safety of pentosan polysulfate sodium (PPS) in relieving symptoms of interstitial cystitis, the authors retrospectively reviewed charts of 260 patients in whom interstitial cystitis had been diagnosed. Subsequently, they conducted a follow-up phone interview or mail survey of those patients who were treated with PPS to investigate changes in the patients' symptoms, adverse effects, and change in quality of life. The control group consisted of patients whose interstitial cystitis had been diagnosed at cystoscopy and had a duration of at least 1 year and who had taken at least one or more oral medications for their symptoms. The average length of treatment was 9.3 months among the 27 subjects on PPS therapy. The mean length of time that they had diagnosed interstitial cystitis was 35.63 months and 48.78 months for the PPS-treated and control groups, respectively, with no statistically significant difference. Changes in frequency, urgency, and pain were greater in the treatment group and statistically significant (P = .11, P = .49, and P = .004, respectively). No change occurred in the rate of nocturia in the PPS-treated group compared with that in the control group. Symptoms of both groups improved over time, but improvement was statistically significantly greater in the treatment group (P = .001) over the treatment interval. The most common side effect attributable to PPS was diarrhea in 15% of subjects. Pentosan proved to be an efficacious option for reducing the debilitating symptoms of interstitial cystitis.

    Epidemiological study of Langerhans cell histiocytosis (LCH) has been limited due to its rarity and multisystemic involvement. The aim of this study was to investigate the epidemiological features of LCH via the clinical data warehouse (CDW). Clinical data of 30 LCH patients from the all departments of a tertiary referral hospital between 2003 and 2012 were analyzed retrospectively by searching the CDW. The male-to-female ratio was 2.8:1. The age of onset ranged 7 days to 57 years with a median of 13 years. Of the patients, 36.7% presented initial symptoms before the age of 10 years. The involved organs at diagnosis were: bone (66.7%), skin (16.7%), lungs (13.3%) and lymph node (3.3%). For all of the 30 cases, there were 31 disease sites because of a single case of multisystemic disease involving both skin and bone. Of the 96.7% of patients with single-system disease, 69.0% had bony involvement. This study elucidated the clinical features of LCH from all the departments of a tertiary hospital via the CDW, which suggests a potential role of the CDW as a new epidemiological approach for rare diseases.

    Objective: The counterclockwise rotation of the SMV on SMA is a normal and non-specific finding, which results in an incomplete swirl formation on CT scans. However, it has a potential to be misinterpreted as ‘midgut volvulus’ resulting in serious clinical implications. The study was done to determine the frequency and degree of counterclockwise rotation of the SMV on SMA on CT in normal otherwise asymptomatic pediatric patients undergoing CT scan. Methods: In this IRB approved study, we retrospectively analyzed abdominal CT scan examinations of 200 consecutive pediatric patients (age range of 11 days to 18 years), which were performed for different clinical indications over a period of 10 months. They were evaluated for the absence or presence and degree of counterclockwise rotation of the mesenteric vessels. Results: Of the 200 patients, 128 (64%) patients showed no clockwise or anticlockwise rotation of mesenteric vessels. Counterclockwise rotation of SMV on SMA was seen in 72 (36%) patients. Further, the degree of rotation of vessels was also calculated, based on the criteria proposed by the authors. Conclusions: The counterclockwise rotation of SMV on SMA gives an appearance of mesenteric whirlpool in otherwise normal mesenteric vessels and can be misinterpreted as midgut volvulus. It is a normal CT appearance and is due to a variation in branching pattern of mesenteric vessels. Awareness of this normal branching pattern of mesenteric vessels is important to avoid an inadvertent laparotomy.

  14. Diagnosis and surgical treatment of renal hydatid disease: a retrospective analysis of 30 cases.

    Mulati Rexiati

    Full Text Available Echinococcosis (CE is an infection which is caused by the larval stage of a tapeworm and is endemic in stockbreeding regions of developing countries. The kidney is the most commonly affected organ in the urinary tract. However, reports on renal hydatid disease are limited in the literature, and usually there are no specific clinical characteristics and promising operative methods. The purpose of this study is to assess the most appropriate surgical technique for the patient with urinary tract CE. We retrospectively analyzed thirty patients with renal hydatid cysts who received different surgical treatments in the urology department of the First Affiliated Hospital of Xinjiang Medical University from February 1985 to April 2010. Twenty patients were males and ten were females. The diagnostic accuracy was 74%, 87.5%, and 66.6% respectively by using of ultrasound, CT, and laboratory tests. Thirty patients were followed up for 1-15 years after surgery. One patient experienced a recurrence of renal CE. The ultrasound, CT, and immunological tests are an important means of diagnosis. The surgical treatment principle of renal hydatid should be based on residual renal function, hydatid cyst size, number, location, and surgical techniques to determine the surgical plan to retain the renal function.

    Full Text Available Objectives. The propofol infusion syndrome (PRIS, a rare, often fatal, condition of unknown etiology, is defined by development of lipemic serum, metabolic acidosis, rhabdomyolysis, hepatomegaly, cardiac arrhythmias, and acute renal failure. Methods. To identify risk factors for and biomarkers of PRIS, a retrospective chart review of all possible PRIS cases during a 1-year period was conducted at a level 1 trauma hospital in ICU patients over 18 years of age receiving continuous propofol infusions for ≥3 days. Additional study inclusion criteria included vasopressor support and monitoring of serum triglycerides and creatinine. Results. Seventy-two patients, 61 males (84.7% and 11 females (15.3%, satisfied study inclusion criteria; and of these, 3 males met the study definition for PRIS, with 1 case fatality. PRIS incidence was 4.1% with a case-fatality rate of 33%. The mean duration of propofol infusion was 6.96 days. A positive linear correlation was observed between increasing triglyceride levels and infusion duration, but no correlation was observed between increasing creatinine levels and infusion duration. Conclusions. Risk factors for PRIS were confirmed as high dose infusions over prolonged periods. Increasing triglyceride levels may serve as reliable biomarkers of impending PRIS, if confirmed in future investigations with larger sample sizes.

    Whether young people should specialise in one competitive sport at an early age, or pursue a wider range of sports during adolescence is a topic of some debate (Baker, Cobley, & Fraser-Thomas, 2009) and is fundamental within sports policy and coaching practice. The purpose of this retrospective recall study was to identify whether early specialisation or sporting diversification (sampling) throughout childhood and adolescence can influence performance levels prior to adulthood. An online questionnaire was used to collect the sport participation histories of 1006 UK sports people, which were then compared with the developmental framework provided by the Developmental Model of Sport Participation (DMSP, Côté & Fraser-Thomas, 2007). A significant association between the number of sports participated in at the ages of 11, 13, and 15 and the standard of competition between 16 and 18 years was found. Individuals who competed in three sports aged 11, 13, and 15 were significantly more likely to compete at a national compared with club standard between the ages of 16 and 18 than those who practised only one sport. The findings reported here provide some empirical support for the sampling performance pathway DMSP model in a UK context.

    Emilio Mezzenga

    Full Text Available The purpose of this study was to retrospectively evaluate the results from a Helical TomoTherapy Hi-Art treatment system relating to quality controls based on daily static and dynamic output checks using statistical process control methods. Individual value X-charts, exponentially weighted moving average charts, and process capability and acceptability indices were used to monitor the treatment system performance. Daily output values measured from January 2014 to January 2015 were considered. The results obtained showed that, although the process was in control, there was an out-of-control situation in the principal maintenance intervention for the treatment system. In particular, process capability indices showed a decreasing percentage of points in control which was, however, acceptable according to AAPM TG148 guidelines. Our findings underline the importance of restricting the acceptable range of daily output checks and suggest a future line of investigation for a detailed process control of daily output checks for the Helical TomoTherapy Hi-Art treatment system.

    Full Text Available Fragile X syndrome (FXS is associated with behavior that limits functioning, including distractibility, hyperactivity, impulsivity, hyperarousal, anxiety, mood dysregulation, and aggression. Medication response and side effect data were reviewed retrospectively for 257 patients (age 14±11 years, range 4–60 years, 203 M, 54 F attending an FXS clinic. Treatment success rates were defined as the percentage of positive response in the form of documented clinical report of improvement in the behavior(s being targeted over at least a 6-month period on the medication, without side effects requiring medication discontinuance, while failures were defined as discontinuance of medication due to lack of clinical effectiveness or side effects. Success rate for treatment of targeted behaviors with trials of individual medications was 55% for stimulants, 53% for antidepressants, 62% for alpha2-agonists, and 54% for antipsychotics. With sequential trials of different medications in the same class, success rate improved to 73–77%. Side effect-related failures were highest for antipsychotics. Systematic psychopharmacologic intervention targeted to behavioral symptoms appears helpful in the majority of patients with FXS.

    Authors investigated sedation quality in children for auditory brainstem response testing. Two-hundred and seventy-six sedation procedures were retrospectively analyzed using recorded data focusing on efficacy of sedation and complications. Intramuscular ketamine-midazolam-atropine combination was administered on sedation preceded by narcotic suppository as pre-medication. On using the combination vital parameters remained within normal range, the complication rate was minimal. Pulse rate, arterial blood pressure and pulse oxymetry readings were stable, hypoventilation developed in 4, apnoea in none of the cases, post-sedation agitation occurred in 3 and nausea and/or vomiting in 2 cases. Repeated administration of narcotic agent was necessary in a single case only. Our practice is suitable for the sedation assisting hearing examinations in children. It has no influence on the auditory brainstem testing, the conditions necessary for the test can be met entirely with minimal side-effects. Our practice provides a more lasting sedation time in children during the examination hence there is no need for the repetition of the narcotics.

    Background Simultaneous pancreas-kidney transplantation (SPKT) is the best treatment option for diabetic patients with advanced chronic renal failure. The current study aimed to analyze the surgical indications, treatments and prognosis of SPKT.Methods We retrospectively analyzed 40 cases of SPKT performed between December 1999 and January 2010 in our center, including the survival rate, complications and the reasons of reoperation.Results Of all the 40 SPKT cases, the one-year survival rates of the recipients, kidney and pancreas transplant graft were 97.6%, 97.6% and 92.7%, while 97.6%, 91.1%, 92.7% at 3 years and 83.6%, 78.0%, 79.4% at 5 years, respectively.After SPKT, 10 patients need reoperation because of surgical complications (14 operations). The reoperation rate was 25%, including 2 patients (4 operations) with hematuria, 4 patients with abdominal hemorrhage, 2 patients (3 operations)with abdominal infection, 1 patient with pancreatic venous thrombosis, 1 patient with anastomotic leakage, and 1 patient with fistula.Conclusion Although SPKT provides a successful and effective treatment for diabetics with end-stage renal disease,how to reduce the complications of this treatment still need further effort.

    There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long-term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ≥ 16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular-attenders) based on their responses to three questions on lifetime dental-attendance patterns. The association between dental-attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio-economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long-term dental attendance and caries experience was found in adjusted models. Former and never regular-attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular-attenders. No differences in DMFT or its components were found between current and always regular-attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses.

    The aim of the study was to evaluate the process of the attention to emergencies in patients older than 65 years and to compare it with the same process in adult patients. To this end, 965 clinical records of medical emergencies from the Hospital Central de la Cruz Roja in Madrid were retrospectively evaluated, and data were obtained regarding age, the cause for consultation, the investigations performed and their yield, the administration of drug therapy, the major diagnosis at the time of discharge from the service and the clinical course. It was found that all evaluated diagnostic investigations were carried out with equal or higher frequency in patients older than 65 years and that their mean clinical effectiveness was also higher. In addition, it was found that the patients older than 65 years were more commonly admitted to the hospital through the emergency service than the rest of the population. It was concluded, therefore, that the process of attention to emergencies has differential characteristics in the elderly population, and that if the number and proportion of old people increase as it will presumably happen during the two next decades, the cost of attention to emergencies and the number of emergency hospital admissions will also increase.

    Acquired hemophilia A (AHA) is a rare bleeding disorder caused by the autoantibody directed against factor VIII in patients without previous history of a bleeding disorder. We retrospectively analyzed the characteristics and outcomes of 49 patients with AHA diagnosed in our center from February 1994 to October 2012. Twenty-four patients with acute bleeding episodes were treated with prothrombin complex concentrate (PCC) at a relative low dose of 30 to -50 U/kg/d and achieved good outcomes without any adverse reaction. Corticosteroids alone or in combination with cyclophosphamide were used as the first-line therapy to eradicate the inhibitors. In 39 evaluable patients, 35 (89.7%) achieved complete remission (CR). This study demonstrates that when bypassing agents such as recombinant activated factor VII and activated PCCs are not affordable or available, low dose PCC is effective and safe to control acute bleeding in patients with AHA. First-line therapy achieved good outcomes with a CR rate of 89.7%.

    Objective To determine the characteristics of women with maternal tetanus, pattern of presentation and outcome of management.Methods A total of 19 women were managed with maternal tetanus between 1990 and 2005 from the University College Hospital in Ibadan Nigeria. A retrospective study was performed. The medical records of all women managed as a case of maternal tetanus were retrieved from the central record department of the hospital The pattern of presentation, characteristics of women, the duration of hospital admission, tetanus toxoid immunization, and outcome of care were measured.Results The records of 18 women managed were analyzed. The mean age at presentation was 25.2±5.3 years. The patients were mostly single, nulliparous and had primary school education. The maternal tetanus cases seen mainly complicated induced abortion while 5 and 2 other cases were due to childbirth complication and leg wound respectively. The portal of entry of the remaining 3 cases could not be ascertained.None of the patient managed had complete immunization schedule. The average duration of admission was 11.2±6. 7 d. Five women had intensive care with 3 of them requiring ventilatory support. The case fatality rate was 66. 7%. The only factor that significantly improved survival was presence of generalized spasm at presentation (P=0. 006) Conclusion The occurrence of maternal tetanus is a reflection of low quality of health care delivery and lack or inefficient routine immunization coverage in any community.

    Objective: To explore the clinical characteristics, diagnosis and treatment of pulmonary sarcoma and blastoma. Methods: Seven cases of pulmonary sarcoma (including 1 case of pulmonary carcinosarcoma, 1 case of pulmonary malignant fibroneuroma, 1 case of pulmonary malignant fibrous tissue tumor and 1 case of pulmonary blastoma from August 1995 to June 2002 in our hospital) were retrospectively summarized the histological characteristics, clinical features, diagnosis and treatment. Results: Pulmonary sarcoma and blastoma both are rare malignant tumors and can be easily misdiagnosed or mistreated. The main symptoms of both diseases are cough and expectoration. X ray or CT shows node or focus in lung. They both are diagnosed by histological pathology. Because the symptoms of these diseases are not typical, it is difficult for patients to be diagnosed without pathology. Conclusion: These two kinds of diseases are often easy to be misdiagnosed. Early diagnosis and treatment are important to improve the efficiency of treatment. Surgical resection is the best method of treatment, and it is important to combine with chemotherapy and radiation treatment.

    Background Pulmonary embolism (PE) is often mistaken as acute coronary syndromes (ACS) because of the considerable overlap in their clinical features.We evaluated the factors causing misdiagnosis of PE as ACS and factors that differentiate PE from ACS to improve the diagnosis efficacy of PE.Methods The medical records of 22 consecutive PE patients,between 2001 and 2010,who were initially suspected of ACS were retrieved.ACS was ruled out by coronary artery angiography before a definite diagnosis of PE was given.Twenty-two contemporary cases of ACS matched by age and sex were recruited as controls.Clinical manifestations,electrocardiograms (ECG),and biomarkers of these patients were reviewed retrospectively.The factors causing misdiagnosis of PE as ACS and factors differentiating PE from ACS were evaluated.Results We found two leading causes of misdiagnosis of PE as ACS.One is that PE can resemble ACS in several clinical aspects (symptoms and signs,ECG findings,plasma cardiac troponin I,and D-dimer).The other is the insufficient recognition of PE by clinicians.Risk factors for venous thromboembolism (VTE),especially deep venous thrombosis (DVT),together with signs of PE,such as unexplained dyspnea or hypoxemia,and right ventricular pressure overload on ECGs are valuable in differentiating the two diseases.Conclusions Differentiation between PE and ACS is sometimes challenging.Adequate awareness of the risk factors for VTE and the signs of PE are crucial in the diagnosis of PE.

    Full Text Available Abstract Oral manifestations are common findings in human immunodeficiency virus (HIV infected patients and frequently influence the overall health. Oral hairy leukoplakia (OHL is strongly associated with HIV infection demonstrating its relationship with the individual’s immune status and progression of immunosuppression. This study aims to retrospectively evaluate OHL in HIV patients, analyzing its incidence, demographic aspects and possible changes in clinical and epidemiological profile of the disease over 17 years. The records of 1600 HIV-infected patients were reviewed. The data were correlated and analyzed, considering HIV exposure category, age, gender, harmful habits, CD4 level, use and type of antiretroviral. OHL was observed in 215 (13.4% patients. Most were men in the fourth decade of life, 171 (79.5% and 112 (52,1% respectively, but an increase in the incidence of OHL among female patients and those in the fifth decade of life was observed. Tobacco smoking was the most frequent harmful habit reported by 114 (68% patients. OHL occurred mostly in patients with CD4 counts between 200 and 500 cells/mm3 35 (55.5%. The lower incidence of OHL was found among patients using at least one non-nucleoside reverse transcriptase inhibitor (NNRTI. OHL is related to CD4 count, use of ARVT and tobacco smoking and is also more prevalent in men in the fourth decade of life. These characteristics were recognized in absolute values, but when verifying the behavior over the years we noticed that the incidence of OHL is decreasing and its epidemiological characteristics changing.

    Full Text Available Abstract Background Pediatric patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT often receive intravenous liposomal amphotericin B (L-AmB as antifungal prophylaxis. There are no guidelines for antifungal prophylaxis in children in this situation. Caspofungin (CAS, a broad-spectrum echinocandin, could be an effective alternative with lower nephrotoxicity than L-AmB. Methods We retrospectively analyzed the safety, feasibility, and efficacy of CAS in our center, and compared the results with L-AmB as antifungal monoprophylaxis in pediatric patients undergoing HSCT. 60 pediatric patients received L-AmB (1 or 3 mg/kg bw/day and another 60 patients received CAS (50 mg/m2/day as antifungal monoprophylaxis starting on day one after HSCT. The median ages of patients receiving L-AmB and CAS were 7.5 years and 9.5 years, respectively. Results No proven breakthrough fungal infection occurred in either group during the median treatment period of 23 days in the L-AmB group and 24 days in the CAS group. One patient receiving CAS developed probable invasive aspergillosis. During L-AmB treatment, potassium levels significantly decreased below normal values. Patients treated with L-AmB had more drug-related side effects and an increased need for oral supplementation with potassium, sodium bicarbonate and calcium upon discharge as compared with the CAS group. CAS was well-tolerated and safe in this cohort of immunocompromised pediatric patients, who underwent high-dose chemotherapy and HSCT. Conclusion Prophylactic CAS and L-AmB showed similar efficacy in this biggest cohort of pediatric patients after allogeneic HSCT reported, so far. A prospective randomized trial in children is warranted to allow for standardized guidelines.

    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.

    This paper explored the curative effect of combined modality therapy and extended field radiotherapy for early-stage Hodgkin's Lymphoma. 104 cases of early-stage Hodgkin's Lymphoma from Jan 1987 to Dec 2010 in PLA Hospital 307 were retrospectively analyzed, including 76 cases in combined modality therapy group and 28 cases in extended field radiotherapy group, and the long-term efficacy and toxicity of two therapy modalities were evaluated. The results showed that the median survival time of 104 cases was 85.42 months, the complete remission rates of combined modality therapy and extended field radiotherapy groups were 72.4 and 71.4 respectively (P = 0.924); the overall response rates of combined modality therapy and extended field radiotherapy groups were 97.4 and 96.4 respectively (P = 0.779); the 5-year overall survival (OS) rates in the 2 groups were 89.5 and 89.1 respectively, and the 8-year OS rates of the 2 groups were 81.3 and 70.6. No statistical difference was found in above-mentioned 2 groups. Moreover, the 5-year progression free survival (PFS) rates of these 2 groups were 84.2 and 69.0 (P = 0.04), and 8-year PFS rates of these 2 groups were 80.0 and 55.5 (P = 0.04) respectively, the 5-year relapse rates of these 2 groups were 28.1 and 45.6 (P = 0.023) respectively. It is concluded that the combined modality therapy can raise the PFS rate and reduce the relapse rate as compared with extended field radiotherapy for early-stage Hodgkin's Lymphoma, but there is no difference in the overall survival rate between the 2 groups.

    Full Text Available Background: A blood transfusion is a life saving procedure in many instances and it requir es an adequate supply of safe blood. The most important is the selection of blood donors by donor selection criteria. A large number of blood donors are deferred from donating blood for several reasons either temporarily or permanently. A shortage of safe blood donor is frequent and it is important to understand the causes of deferral of potential donors. Aims: 1. Primary objective of this study was to record and document the current rate and reasons for donor deferred in our blood bank. 2. Apply relevant findings to modify recruitment strategy for blood donors. Materials and methods: Data for WBD presenting for blood donation in a blood bank V S General Hospital and outdoor camps over two and half years from January 2011 to June 2013 were analysed retrospectively. National Guidelines were used for selection & deferral of WBD. Results: 3836 (11.16% WBD were deferred out of 34373 registered donors during the study period. Donor deferrals were tabulated into temporary and permanent reasons. Temporary deferrals were 3113 (81.15% and permanent deferrals were 723 (18.85%. The most common reasons were low haemoglobin (48.33%, high blood pressure (11.94%, underweight donors (7.95% and history of medication use (6.13% among total deferral donors. Majority of donors (47.16% deferred were between 18 -30 years. Females were found to have higher deferral rate (25.48% than males (10.76%. Discussion and conclusion: A deferral study in blood donors may shed light on the health status of general population which may affect the present and future blood supply. It is important to provide donors with a clear message on their deferral status so that most of temporary deferral donors will return for donation in future.

    Incidence and etiology of facial fractures vary from region to region due to various constituents. This study was carried to evaluate the patterns and distribution of fractures in the facial region among different age groups of patients in both males and females caused due to various etiologies. This is a retrospective epidemiological study, which was performed on patients with fractures in the maxillofacial region during a period of 2005 to 2013 at Mamata Dental College and Hospital, Khammam, India. A total of 1,015 patients with 1,545 fractures were referred for treatment to department of oral and maxillofacial injuries surgery, of Mamata Dental College and Hospital, with a mean age of 31.19. The ratio of males (859):females (156) is 5.5:1. Injuries caused by motorbike injuries (34.9%) are highest. The highest frequency of fractures caused by various reasons is seen more in third decade (39%). Mandible (43.81%) is the most common fracture site in the face. Among soft tissue injuries most commonly seen are lacerations (43%). This study differentiates the etiological factors causing facial trauma in several age groups. Results of this study suggest outcomes indicate that more reliance on individual transport on motor vehicles has increased the frequency of facial bone fractures. Regardless of age, motor vehicle accidents were high in all age groups except the first decade of life and above 60 years of age when traffic accidents dominated. Thus effectiveness of current preventive measures is to be assessed, followed by instituting new guidelines for prevention and inflexible traffic rules shall be levied. More epidemiological surveys can, if encouraged to measure the frequency of fractures, better the world. PMID:26576235

    Full Text Available Background: Breast cancer markers are becoming increasingly important in breast cancer research due to their impact on prognosis, treatment and survival. The present retrospective study was carried out to quantify the proportion of estrogen (ER, progesterone (PR, and human epithelial receptor 2 (HER2 expressions and their association with tumour grade, age, and tumour size in breast cancer patients in Nigeria. Materials and methods: The paraffin embedded tissue sections were analysed for breast cancer markers using monoclonal antibody SP1 for ER and SP2 for PR and polyclonal antibody ErbB2 for HER2. Results: A total of 286 breast cancer paraffin wax tissue sections were analysed for ER, PR and HER2 expression. Of all the tissue samples examined, 20 (7% were ER-positive, 6 (2.1% were PR-positive, 11 (3.8% were HER2-positive whereas 248 (87% were triple-negative breast carcinoma. ER- and PR-positivity was associated with early grade I and II tumours (P 50mm (P < 0.0001. Conclusion: A small proportion of Nigerian women with breast cancer are ER/PR-positive which are associated with less aggressive, better prognosis and benefit from endocrine therapy. An even smaller proportion of patients with aggressive tumors were HER2-posivite but responsive to Herceptin treatment. Unfortunately, a very high proportion of cases were triple-negative which is associated with very aggressive tumours and no targeted treatment, which may explain the high mortality rates from breast cancer in Nigeria.

    Full Text Available Background The aim of this study was to assess the prevalence of hospitalisation for otitis media across the different risk indicators for Western Australian children (less than 15 years old over a 10-year period. Method This retrospective population-based study used the deidentified detailed data of children under the age of 15 years, hospitalised for otitis media (OM, as determined by principal diagnosis (ICD-10AM and obtained from the Western Australian (WA Hospital Morbidity Dataset for 10 financial years from 1999–2000 to 2008–2009. Various risk indicators, including age, gender, Indigenous status, insurance status, hospital area, hospital type, and length of stay were also analysed. Results Out of 26,294 cases of in-hospital care, Indigenous children comprised 4.7 per cent (n=1,226, while the non-Indigenous children comprised 95.3 per cent (n=25,068. The majority of the children, nearly 98.8 per cent, were admitted for chronic OM. The children were grouped into three age groups, namely, 0–4 years, 5–9 years, and 10–14 years. Nearly two-thirds of all cases were in the 0–4-year age group. Significantly more non-Indigenous (51 per cent than Indigenous children (2 per cent had private health insurance. The hospitalisation rates were directly proportional between the number of Indigenous children living in the area and the increasing remoteness of the area along with greater socioeconomic disadvantage. There were 24 per cent more cases from very remote areas compared to highly accessible areas, and there were 60 per cent more cases from the most disadvantaged socioeconomic category, compared with the least disadvantaged category, for Indigenous children. Conclusion These data depict the variations in prevalence of otitis media hospitalisations within the community, as affected by various risk indicators.

    Full Text Available To assess the characteristic findings and effects of laser capsulotomy in patients with late postoperative capsular bag distension syndrome (CBDS.Twenty patients diagnosed with late postoperative CBDS between July 2010 and August 2013 were retrospectively reviewed. Before and 1 week after capsulotomy, changes in the anterior chamber depth (ACD were assessed using ultrasound biomicroscopy. Changes in the refractive status and uncorrected visual acuity (UCVA were also measured 1 week and 1 month after capsulotomy. For patients who received bilateral cataract surgery, preoperative ACD and axial length measured by IOLMaster were compared between the two eyes.Twenty-two eyes from 20 patients who had undergone laser capsulotomy showed a mean UCVA improvement of 0.27 ± 0.24 logMAR (range, 0.00-0.90. ACD was increased by an average of +0.04 mm (95% confidence interval, +0.01 to +0.06 mm, p = 0.034, equivalent to predicted refractive change of +0.10 D. The discrepancy between actual (+1.33 D and predicted refractive change after capsulotomy suggests that refractive change may not be generated from IOL displacement in late postoperative CBDS. Preoperative ACD was deeper in the eye with late postoperative CBDS in all bilaterally pseudophakic patients (mean, 3.68 mm vs. 3.44 mm in the fellow eye, p = 0.068.Late postoperative CBDS showed refractive changes that were resolved successfully after laser capsulotomy. The convex lens effects of opalescent material in the distended capsular bag may play a major role in myopic shift. A larger preoperative ACD is possibly associated with the development of late postoperative CBDS.

    Renal cell cancer (RCC) is characterized by histological and molecular heterogeneity that may account for variable response to targeted therapies. We evaluated retrospectively with a next generation sequencing (NGS) approach using a pre-designed cancer panel the mutation burden of 32 lesions from 22 metastatic RCC patients treated with at least one tyrosine kinase or mTOR inhibitor. We identified mutations in the VHL, PTEN, JAK3, MET, ERBB4, APC, CDKN2A, FGFR3, EGFR, RB1, TP53 genes. Somatic alterations were correlated with response to therapy. Most mutations hit VHL1 (31,8%) followed by PTEN (13,6%), JAK3, FGFR and TP53 (9% each). Eight (36%) patients were wild-type at least for the genes included in the panel.A genotype concordance between primary RCC and its secondary lesion was found in 3/6 cases. Patients were treated with Sorafenib, Sunitinib and Temsirolimus with partial responses in 4 (18,2%) and disease stabilization in 7 (31,8%). Among the 4 partial responders, 1 (25%) was wild-type and 3 (75%) harbored different VHL1 variants. Among the 7 patients with disease stabilization 2 (29%) were wild-type, 2 (29%) PTEN mutated, and single patients (14% each) displayed mutations in VHL1, JAK3 and APC/CDKN2A. Among the 11 non-responders 7 (64%) were wild-type, 2 (18%) were p53 mutated and 2 (18%) VHL1 mutated.No significant associations were found among RCC histotype, mutation variants and response to therapies. In the absence of predictive biomarkers for metastatic RCC treatment, a NGS approach may address single patients to basket clinical trials according to actionable molecular specific alterations.

    Full Text Available Abstract Background Analyses of utilization trends (cost drivers allow us to understand changes in colorectal cancer (CRC costs over time, better predict future costs, identify changes in the use of specific types of care (eg, hospice, and provide inputs for cost-effectiveness models. This retrospective cohort study evaluated healthcare resource use among US Medicare beneficiaries diagnosed with CRC between 1992 and 2002. Methods Cohorts included patients aged 66+ newly diagnosed with adenocarcinoma of the colon (n = 52,371 or rectum (n = 18,619 between 1992 and 2002 and matched patients from the general Medicare population, followed until death or December 31, 2005. Demographic and clinical characteristics were evaluated by cancer subsite. Resource use, including the percentage that used each type of resource, number of hospitalizations, and number of hospital and skilled nursing facility days, was evaluated by stage and subsite. The number of office, outpatient, and inpatient visits per person-year was calculated for each cohort, and was described by year of service, subsite, and treatment phase. Hospice use rates in the last year of life were calculated by year of service, stage, and subsite for CRC patients who died of CRC. Results CRC patients (mean age: 77.3 years; 44.9% male used more resources than controls in every category (P Conclusion Use of hospice care among CRC decedents increased substantially over the study period, while other resource use remained generally steady. Our findings may be useful for understanding CRC cost drivers, tracking trends, and forecasting resource needs for CRC patients in the future.

    OBJECTIVE: To quantify cumulative exposure to ionizing radiation in patients with end stage kidney disease (ESKD). To investigate factors which may be independently associated with risk of high cumulative effective dose (CED). MATERIALS AND METHODS: The study had local institutional review board ethical approval. We conducted a retrospective study of 394 period prevalent ESKD patients attending a single tertiary referral centre between 2004 and 2009. Patient demographics were obtained from case records. Details of radiological investigations were obtained from the institutional radiology computerized database. CED was calculated using standard procedure specific radiation levels. High exposure was defined as CED > 50 mSv, an exposure which has been reported to increase cancer mortality by 5%. Data were compared using Pearson χ(2) and Mann-Whitney U test or Kruskal-Wallis tests. RESULTS: 394 patients were followed for a median of 4 years (1518 patient years follow-up). Of these 63% were male. Seventeen percent of patients had a CED of >50 mSv. Computed tomography (CT) accounted for 9% of total radiological studies\\/procedures while contributing 61.4% of total study dose. Median cumulative dose and median dose per patient year were significantly higher in the hemodialysis (HD) group (15.13 and 5.79 mSv, respectively) compared to the post-transplant group (2.9 and 0.52 mSv, respectively) (P < 0.001). CONCLUSION: ESKD patients are at risk of cumulative exposure to significant levels of diagnostic radiation. The majority of this exposure is imparted as a result of CT examinations to patients in the HD group.

    Therapeutic plasma exchange (TPE), is a procedure, changing pathologic substances in the plasma of patients with replacement fluid. TPE has an increasing list of indications in recent years such as neurological, connective tissue, hematological, nephrological, endocrinological and metabolic disorders. We report our multicenter data about therapeutic plasma exchange in patients with neurological diseases. Six University Hospitals' aphaeresis units medical records about neurologic diseases were reviewed retrospectively. Hundred and fifteen patients and 771 TPE sessions from six aphaeresis units' were included to this study. Of the 115 patients, 53 (46%) were men and 62 (54%) were women. The median age was 50 (range: 5-85) years. Of these patients 58.3% were Guillain-Barre syndrome (GBS), 17.4% were acute disseminated encephalomyelitis (ADEM), 10.4% were chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), 7% were multiple sclerosis, 6.1% were myasthenia gravis (MG) and 0.9% were Wilson disease (WD). The median number of TPE sessions per patient was 5 (range 1-72). Human albumin was used as a replacement fluid in 66% and fresh frozen plasma was used in 34% of cases. TPE was done through central venous catheters in 66%, and peripheral venous access in 34% of patients. Some complications were seen in patients (18.3%) during TPE sessions. These complications were, complications related to catheter placement procedure (8.7%), hypotension (3.5%), hypocalcaemia (3.5%) and allergic reactions (1.7%). The complication ratios were 2.7% in total 771 TPE procedures. TPE procedure was terminated in 6% of sessions depending on these complications. Overall responses to TPE were noted in 89.5% of patients. In conclusion; Therapeutic plasma exchange is an effective treatment option in several neurologic diseases.

    Full Text Available Background: Biopsy is an important diagnostic tool used in the diagnosis of lesions ranging from simple non-neoplastic, tumor-like lesions to malignancies, and is often the only way to diagnose oral lesions and diseases. The gingiva is the most common site for some kind of irritation or low-grade injury, resulting in localized overgrowths that are considered to be reactive and non-neoplastic lesions. This aim of this study is to analyze the frequency and distribution of gingival lesions in the Gujarati population. Materials and Methods: In this retrospective study, gingival biopsies submitted for a period of five years were included. Microscopic slides of all the cases were reviewed by two observers for confirmation of the diagnosis. Results: Among the 106 cases of gingival biopsies, the most frequent category of lesions encountered was the non-neoplastic category, which accounted for 73.58% of the cases. Both benign and malignant neoplasms constituted 26.42% of the cases. Among the non-neoplastic lesions, Pyogenic granuloma was the most frequent lesion (38.46%, followed by fibrous hyperplasia (20.51%, inflammatory hyperplasia (19.23%, and Epulis (8.97%. Neoplasms accounted for 26.42% of the gingival biopsies (92.85% benign and 7.15% malignant. Among the benign neoplastic lesions, Fibroma (30.76% and Fibrolipoma (26.92% were the most frequent, followed by peripheral ossifying fibroma (23.08% and peripheral giant cell granuloma (11%. Conclusion: It is difficult to compare studies carried out in various countries due to differences in people′s attitudes toward oral health and the accessibility of various population groups to biopsy services. Nevertheless, this study has provided some information about the frequency and distribution of biopsied gingival lesions in the Gujarati population over a period of five years.

    AIM:To describe the characteristics of Dutch patients with chronic.inflammatory bowel disease (IBD) first diagnosed above 60 years of age-a disease also known as old-age colitis (OAC) and to highlight a condition that has a similar appearance to IBD,namely segmental colitis associated with diverticular disease (SCAD).METHODS:A retrospective longitudinal survey of patient demographic and clinical characteristics,disease characteristics,diagnostic methods,management and course of disease was performed.The median follow-up period was 10 years.RESULTS:Of a total of 1100 IBD patients attending the Department of Gastroenterology,59 (5%) [median age 82 years (range 64-101);25 male (42%)] were identified.These patients were diagnosed with ulcerative colitis (n = 37,61%),Crohn's disease (n = 14,24%),and indeterminate colitis (n = 8,15%).Remission was induced in 40 (68%) patients within a median interval of 6 mo (range 1-21) and immunosuppressive therapy was well tolerated.Histological evaluation based on many biopsy samples and the course of the disease led to other diagnosis,namely SCAD instead of IBD in five (8%) patients.CONCLUSION:OAC is not an infrequent problem for the gastroenterologist,and should be considered in the evaluation of older patients with clinical features suggestive of IBD.Extra awareness and extensive biopsy sampling are required in order to avoid an erroneous diagnosis purely based on histological mimicry of changes seen in SCAD,when diagnosing IBD in the presence of diverticulosis coll.

    Full Text Available Objective: Ventilator-associated pneumonia (VAP is the most common nosocomial infection in the intensive care units (ICUs. It causes prolonged hospital stay and increases mortality. In this study, we aimed to investigate the rate of VAP, causative microorganisms, and their antibiotic susceptibilities in anaesthesiology and reanimation ICU (ARICU. Material and Method: This retrospective study included patients who were admitted to 12-bed ARICU between January 2013 and December 2014. The detection of VAP was done according to Centers for Disease Control and Prevention criteria. The rate of VAP, VAP ratio, and ventilator utilization ratio (VUR were calculated according to guidelines of Turkish National Infection Surveillance Control Group. Endotracheal aspiration samples were collected and cultivated. The identification of the isolates was performed by using VITEK-2 automated system. Antibiotic susceptibilities were determined by the disc diffusion method according to the Clinical and Laboratory Standards Institute criteria. Results: VAP was determined in 16 of 359 patients who required invasive mechanic ventilation for longer than 48 hours and hospitalized in ARICU. VUR was 65%, VAP ratio was 4.5% and the rate of VAP was 3.3 per 1000 ventilator days. Seventeen microorganisms were isolated from endotracheal aspiration samples, including Acinetobacter baumannii (n=6, Pseudomonas aeruginosa (n=4, methicillin-resistant Staphylococcus aureus (n=4, Klebsiella pneumoniae, Enterobacter cloacae and Serratia marcescens. The most sensitive antibiotics for microorganisms are listed as follows; Acinetobacter baumannii: colistin, Pseudomonas aeruginosa: amikacin, carbapenems; Methicillin-resistant Staphylococcus aureus: linezolid, teicoplanin, vancomycin, trimethoprim sulfamethoxazole; Klebsiella and Enterobacteriaceae species: carbapenems, trimethoprim sulfamethoxazole, gentamicin. Conclusion: Intermittent analyses and antibiotic susceptibilities of VAP

    Full Text Available The appropriate management of minor head injury (MHI in patients receiving oral anticoagulant (OAC is unclear. In this retrospective study, we focused on elderly patients (>65 years treated with OAC, presented to our emergency department with MHI between 2004 and 2010. Three hundred and six patients with MHI were taking OAC: we documented 7.19% hemorrhages at the first computed tomography (C; 18.19% deaths; 50.1% spontaneous reabsorptions; 22.73% deteriorations of intracranial bleeding without surgical intervention (for clinical comorbidity, and 4.55% neurosurgical interventions. We documented a second positive CT scan in 2 patients (1.51% who had no symptoms and remained asymptomatic during observation. In both cases, intracranial bleeding resolved spontaneously. The mean international normalized ratio (INR value was 2.26, higher in the group of patients with bleeding (2.74 than in the group without bleeding (2.19. We found a significant increased risk in patients with posttraumatic loss of consciousness [odds ratio (OR 28.3], diffuse headache (OR 14.79, vomiting (OR 14.2 and neurological signs (OR 5.27. We did not reach significance in patients with post-traumatic amnesia. Our data confirm the need for a CT scan of any patients on OAC with MHI. None of our patients developed any symptoms or signs during observation, and only 2 patients developed an intracranial hemorrhage in the second CT scan with a favorable evolution. Our data need to be confirmed with an observational study, but we suggest that the second CT could be reserved for patients developing symptoms and signs during observation. We also underline the role of the INR in the stratification of risk.

    Background and study aims: Percutaneous endoscopic gastrostomy (PEG) using the introducer technique is not only useful in patients with upper digestive tract stenosis but has been shown to reduce peristomal infection. In this study, we evaluated the safety and utility of a novel large-caliber introducer PEG kit (using 20 Fr size tube) compared with a push kit of similar size. Patients and methods: One hundred and thirty-six patients who received PEG at our hospital between January 2014 and December 2015 were retrospectively analyzed. Baseline characteristics, laboratory biomarkers, hemodynamic changes, postoperative adverse events and clinical outcomes with both kits were compared. Results: The new introducer PEG kit was used in 61 patients while the remaining 75 patients received tube placement using a push technique PEG kit. Except for the prevalence of dementia, which was lower in the introducer PEG kit group, baseline characteristics were similar in both groups. Tube placements were 100 % successful with both PEG kits and there were no significant differences in the change of postoperative hemodynamic or laboratory biomarkers. The Introducer PEG kit group experienced fewer incidence of feeding-related aspiration pneumonia (8.2 % vs. 24 %, P = 0.02), lower peristomal infection scores (1.2 vs. 1.6, P < 0.01), shorter postoperative length of stay (16 days vs. 23.7 days, P = 0.01) and fewer deaths at day 60 (3.3 % vs. 16 %, P = 0.02). Conclusions: Gastrostomy using the new large-caliber introducer PEG kit is safe and produced non-inferior (with some favourable) results when compared to the push technique using similar size tubes.

    Background There exists great heterogeneity in patient survival and the time interval between motor symptom and dementia onset (MDI) across Lewy body spectrum disorders (LBSD). The goal of this study is to identify genetic and pathological findings that have the strongest association with these features of clinical heterogeneity in LBSD. Methods In this retrospective study, we examined symptom onset, and genetic and neuropathological data from a cohort of LBSD patients with autopsy-confirmed α-synucleinopathy (as of Oct 1, 2015) recruited from 5 clinical research centres in 5 cities in the USA. Using histopathology techniques and markers, we assessed the burden of tau neurofibrillary tangles, neuritic plaques, α-synuclein inclusions, and other pathologic changes in cortical regions using averaged ordinal scores and genotyped cases for variants associated with LBSD. We evaluated the time interval from onset of motor symptoms to dementia (MDI) and overall survival in groups with varying levels of co-morbid Alzheimer’s disease pathology (AD) according to current National Institute on Aging–Alzheimer’s Association neuropathological criteria and used multivariate regression to control for age at death and gender. Findings This study included 213 patients who had been followed to autopsy and met inclusion criteria of clinical LBSD with autopsy-confirmed α-synculeinopathy. Patient groups were characterized by no (n=49,23%), low-level (n=56,26%), intermediate-level (n=45,21%) or high-level (n=63,30%) AD neuropathology. Across groups of increasing levels of AD neuropathology, there were higher cerebral α-synuclein scores, shorter MDI, and shorter disease duration (pdiagnostic criteria which use reliable biomarkers for AD neuropathology in LBSD should help identify the most appropriate patients for clinical trials of emerging therapies targeting tau, amyloid-beta or α-synuclein, and stratify them by level of AD neuropathology.

    Introduction Both, the renal pelvis and the ureter, are affected by developmental, reactive and neoplastic disorders, though rare in incidence. Aim This series of cases were analysed to study the clinicopathological characteristics of the common and comparatively rare lesions involving the renal pelvis and pelviureteric junction. Materials and Methods A retrospective collection of 476 nephrectomies and pelviureteric junction resections, received over a period of 13 years from 2001 to 2013 was done. The patients’ clinical details were obtained and the histopathological findings reviewed. The lesions were classified into non-neoplastic and neoplastic categories. Results Primary involvement of the renal pelvis and pelviureteric junction was seen in 105 of 476 specimens. The mean age was 54.5 years with a male to female ratio of 2.2:1. The non-neoplastic lesions accounted for 76.2% of cases with a majority being pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy (68.6%) causing hydronephrosis. Urothelial carcinomas were encountered in 20% of the cases. A majority of the urothelial carcinomas were infiltrative (81%) and high grade (71%) tumours. Conclusion Renal pelvis, a conduit to propel urine, can be the site for numerous disorders. Non-neoplastic lesions were more common than neoplasms. Pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy was the commonest lesion in our study. In the neoplastic category, urothelial carcinoma was most common. However, rare lesions such as hamartomatous fibroepithelial polyp, Von Brunn’s nests, flat urothelial hyperplasia and intramuscular haemangioma of upper ureter at the pelviureteric junction were encountered along with occasional cases of tuberculosis and squamous cell carcinomas.

    2012-06-01

    Full Text Available Background and Design: Epidermal growth factor receptor (EGFR inhibitors may cause different adverse cutaneous reactions including acneiform (pustular, papulopustular eruption. Rarely, other specific targeted cancer therapy agents may cause similar pustular eruptions. The aim of this study was to evaluate the adverse skin reactions, mainly acneiform eruptions caused by these chemotherapeutic agents. Material and Methods: We retrospectively analyzed the data of 23 patients who developed acneiform eruption due to chemotherapeutic agents between May 2007 and April 2011. The drugs causing acneiform eruption, clinical features of eruption, other associated dermatologic adverse reactions and the treatment modalities used for the acneiform reaction were noted. Results: EGFR inhibitors such as erlotinib and cetuximab were the main drugs causing acneiform eruption in 21 patients. Everolimus and bevacizumab in combination with irinotecan were responsible in two patients. The eruption occurred on the face in all patients. The trunk, neck and the scalp were other affected body parts in some patients. The periorbital area on the face was generally spared. Xerosis and paronychia were the main associated adverse cutaneous reactions. Trichomegaly was another finding in two patients. The patients, who could have been followed, responded to topical or systemic antibiotics, or some medications for acne vulgaris/rosacea. Chemotherapy could be continued in all patients. Conclusion: Dermatologists need to know the specific eruptions occurring with chemotherapy drugs, especially EGFR inhibitors in order to develop the best approach without discontinuation of cancer therapy. Acneiform eruptions due to chemotherapeutics are most commonly seen on the face sparing periorbital area. Other reactions including mainly xerosis, paronychia and trichomegaly can also occur.

    After RANS simulation of full appended SUBOFF submarine's viscous flow with four groups of grids of the same mesh block topology and close mesh quality and five turbulent models, effects of mesh density and nodes distribution and turbulent models on calculation precision were analyzed, and detailed validation of force integral variables and velocity field variables and vorticity of viscous flow were completed at last. Results show that G4 (1.4 million) with the most mesh density can get the high- est precision,which calculated total drag just differ by 0. 723% to the experiment. As for the G4 mesh, choosing the SST model in the calculation is the best. Using G4, the predicted pressure coefficient and wall shear stress coefficient distribution both fit very well with the experiment; The numerical precision of the velocity profiles on propeller disk plane is near to the reference,and the calculated radial position for dimensional axial velocity over 0.9 is a little bigger than the experiment,while the rest is good agree- ment with the data; The precision of the three velocity components at r/R=0. 25 is higher than refer- ence too as a whole, and its axial component fits well with the experiment, the radial components' peak is a little lower while its circumferential position is coincident with the measure. What's more important, RANS simulation of the G4 successfully captures the complexity vorticity structures,including counter- rotating vortex induced by flow over fairwater cap and stern fin's tip surface, necklace-shaped vortex pair downstream of the appendages' root section,shoe-shaped vortex attached upwards of stern fin's tip sur- face trailing edge, horse-shoe vortex system induced by the flow around the appendages, vortex induced by flow extrusion within the passages of stern appendages, and the vortex concentration phenomenon on propeller disk plane,even the phenomenon of counter-rotating vortex induced by flow over fairwater cap being stable

    Full Text Available Relevance of the topic. At the present time laparoscopic appendectomy has taken its own place at the urgent surgery. In spite of this less is studied in the field of the use of the minimally invasive technologies in the cases of complicated acute appendicitis. The aim of research: to investigate the close results of the patients with acute appendicitis treatment with laparoscopic appendectomy, and to compare them with the open appendectomy results; to estimate the possibilities of laparoscopic appendectomy in the cases of complicated acute appendicitis. Materials and methods. The results of surgical treatment of 146 patients with acute appendicitis were analyzed – 59 patients in the main group, who undergone laparoscopic appendectomy, and 80 patients in the control group, who undergone open surgery. 7 patients who passed through conversion were included in the additional group. Results. The frequency of acute appendicitis complications, which were diagnosed during the operation, in the both groups had no significant distinction (50.8 % in the main group and 47.5% in the control group. But 5 patients with diffuse peritonitis and appendicular abscesses needed a conversion of laparoscopic operation into open one, because of the full sanitation necessity and technique difficulties. In the postoperative period among the patients of main group the suppuration of the wound was observed in 2 (3.4% cases, in the control group – in 10 (12.5%. The average duration of laparoscopic operation was 33.12±2.51 min, open surgery – 66.45±3.33 min. The average hospitalization period in the control group was 6.95±0.2 days and was statistically proved higher than in the main group – 4.72±0.21 days (p≤0.01. Conclusion. Laparoscopic appendectomy can be wide used in the cases of acute appendicitis, including complications, but it can be restricted in the cases of diffuse peritonitis and appendicular abscesses.

    Introduction/objective: To determine the value of power Doppler (PD) ultrasonography (US) and contrast-enhanced power Doppler (CEPD) US in the diagnosis of acute appendicitis and the prediction of histopathologic stages. Methods and material: 50 patients with suspected acute appendicitis were evaluated by the same radiologist with PD US and CEPD US. Air micro bubbles stabilized by a granulate of 'galactose and palmitic acid' were used as a contrast medium for sonography with the concentration of 400 mg/ml. PD US and CEPD US results were later correlated with the surgical and histopathologic findings. PD US and CEPD US findings were considered positive for appendicitis; if there was depiction of hyperemia in the wall of the appendix or if there was depiction of prominent peripheral vascularity when compared with normal soft tissues; and negative if both hyperemia and peripheral hyperemia were not prominent. Results and discussions: Of the 50 patients, 35 patients had histopathologically proven acute appendicitis. CEPD US showed prominent hyperemia in the appendiceal vessels or feeding vessels of the inflamed appendix, and resistance index (RI) calculations were easier. There was statistically significant difference between mean RI values of the normal appendix, suppurative appendicitis and gangrenous appendicitis. PD US has accuracy of 80%, sensitivity of 74% and CEPD US has 98%, and 100% in the diagnosis of acute appendicitis. CEPD US identified 100% of suppurative appendicitis and gangrenous appendicitis. Conclusion: CEPD US is a promising method in the diagnosis of acute appendicitis and determination of the inflammation stage.

    AIM: Although the radiological features of acute appendicitis have been well documented, the value of plain radiography has not been fully appreciated. The aim of this study was to determine the frequency of the association of acute appendicitis with images of fecal loading in the cecum.METHODS: Plain abdominal radiographs of 400 patients operated upon for acute appendicitis (n = 100), acute cholecystitis (n = 100), right acute pelvic inflammatory disease (n = 100) and right nephrolithiasis (n = 100)were assessed. The presence of fecal loading was recorded and the sensitivity and specificity of this sign for acute appendicitis were calculated.RESULTS: The presence of fecal loading in the cecum occurred in 97 patients with acute appendicitis, 13 patients with acute cholecystitis, 12 patients with acute inflammatory pelvic disease and 19 patients with nephrolithiasis. The sensitivity of this sign for appendicitis was 97% and its specificity to this disease was 85.3%. Its positive predictive value for appendicitis was 68.7%; however, its negative predictive value for appendicitis was 98.8%.CONCLUSION: The present study suggests that the presence of radiological images of fecal loading in the cecum may be a useful sign of acute appendicitis, and the absence of this sign probably excludes this disease.This is the first description of fecal loading as a radiological sign for acute appendicitis.

    Full Text Available This retrospective study compared the functional outcomes among stroke patients who had received rehabilitation based on different physiotherapy treatment approaches. The participants were divided into three groups according to the physiotherapist in charge of their treatment. The primary treatment approaches applied in Group A, Group B, and Group C were the functional approach, the Bobath approach, and the motor learning approach, respectively. For each participant, the Berg's Balance Scale score, the Modified Barthel Index, and the Modified Rivermead Mobility Index were compared among these three groups prior to and after the stroke rehabilitation programme. Within-group analysis showed that Group A, Group B, and Group C participants had a statistically significant improvement in their Modified Barthel Index (p  0.05. In summary, this study showed that different combinations of treatment approaches may induce similar improvement in functional outcomes after stroke rehabilitation.

    methods, such as centromeric FISH, aimed at determining the variation around the modal number of two or more chromosomes within individual tumor nuclei. Here, we document the frequency of tumor CIN by dual centromeric FISH analysis in a retrospective primary breast cancer cohort of 246 patients...... with survival outcome. Results: There was increased CIN and clonal eterogeneity in ER-negative compared with ER-positive breast cancer. Consistent with a negative impact of CIN on cellular fitness, extreme CIN in ER-negative breast cancer was an independent variable associated with improved long-term survival......Background: Chromosomal instability (CIN) is thought to be associated with poor prognosis in solid tumors; however, evidence from preclinical and mouse tumor models suggest that CIN may paradoxically enhance or impair cancer cell fitness. Breast cancer prognostic expression signature sets, which...

    Full Text Available BACKGROUND: The early diagnosis of acute abdomen is of great importance. To date, several inflammatory markers have been used for the diagnosis of acute abdominal conditions, including acute appendicitis. The aim of this study was to evaluate the diagnostic utility of D-dimer, Procalcitonin (PCT and C-reactive protein (CRP measurements in the acute appendicitis.METHODS: This prospective study was conducted between March 1st, 2010 and July 1st, 2011. In this period, seventy-eight patients were operated with the diagnosis of acute appendicitis, and D-dimer, PCT and CRP levels of the patients were measured. The patients were grouped as phlegmonous appendicitis (Group 1, gangrenous appendicitis (Group 2, perforated appendicitis (Group 3 and negative appendectomy (Group 4 according to the surgical findings and histopathological results.RESULTS: Of 78 patients, 54 (69.2 % were male and 24 (30.8 % were female, and the mean age was 25.4 ± 11.1 years (range, 18 to 69 years. 66 (84.6 % patients had increased leukocyte count (white blood cell count. The PCT values were higher than the upper normal limit in 20 (25.6% patients, followed by D-dimer in 22 (28.2 % patients and CRP in 54 (69.2 % patients. The diagnostic value of leukocyte count and CRP in acute appendicitis was higher than that of the other markers, whereas leukocyte count showed very low specificity. CRP values were higher in perforated appendicitis when compared with the phlegmonous appendicitis (p<0.05. However, PCT and D-dimer showed lower diagnostic values (26% and 31%, respectively.CONCLUSION: An increase in CRP levels alone is not sufficient to make the diagnosis of acute appendicitis. However, CRP levels may differentiate between phlegmonous appendicitis and perforated appendicitis. Due to their low sensitivity and diagnostic value, PCT and D-dimer are not better markers than CRP for the diagnosis of acute appendicitis.

    Full Text Available Aim : The aim of this retrospective study was to assess treatment outcomes for patients with locally advanced gynecological malignancies being treated with interstitial brachytherapy using Martinez universal perineal interstitial template (MUPIT and to study the acute and late sequelae and survival after treatment by this technique. Materials and Methods : Ninety seven patients untreated with histopathological confirmation of carcinoma of cervix (37 vault (40 and vagina (20 were treated by combination of external beam RT (EBRT using megavoltage irradiation to pelvis to dose of 4000-5000 cGy followed by interstitial brachytherapy using MUPIT between September 2001 to March 2005. Median age was 46 years. Only those patients who were found unsuitable for conventional brachytherapy or in whom intracavitatory radiotherapy was found to be unlikely to encompass a proper dose distribution were treated by interstitial template brachytherapy using MUPIT application and were enrolled in this study. The dose of MUPIT was 1600-2400 cGy in 4-6# with 400 cGy /# and two fractions a day with minimum gap of six hours in between two fractions on micro-HDR. Criteria for inclusion of patients were as follows: Hb minimum 10 gm/dl, performance status - 70% or more (Karnofsy scale, histopathological confirmation FIGO stage IIB-IIIB (excluding frozen pelvis. Results : Among the 97 patients studied, 12 patients lost to follow-up and hence they were excluded from the study. Follow-up of rest of the patients was then done up to September 2006. The duration of follow-up was in the range of 20-60 months. Parameters studied were local control rate, complication rate, mortality rate and number of patients developing systemic metastasis. Local control was achieved in 56/85 (64.7% and complication rate was 15/85 (17.6%. Local control was better for nonbulky tumors compared bulky tumors irrespective of stage of disease. Local control was better in patients with good regression of

    The objective of this study is to investigate the characteristics and the evolution of visual field damage caused by Leber's hereditary optic neuropathy (LHON) and to provide clinical data for the diagnosis of LHON. Parameters of visual field in 32 consecutive patients (49 eyes) with LHON who were confirmed by genetic diagnostic tests were retrospectively measured within 1 week, between three to six months, and at six months after onset. Visual field defects revealed central scotoma in 26 eyes (53.1 %), paracentral scotoma in 12 eyes (24.5 %), ceco-central defects in 6 eyes (12.2 %), blind spot enlargenment in 3 eyes (6.1 %), quadrantanopia in 2 eyes (4.1 %) within 1 week after onset. After 3 to 6 months, ceco-central defects were detected in 22 eyes (44.9 %), central isopter constriction in 10 eyes (20.4 %), hemianopia or quadrantanopia in 5 eyes (10.2 %), central scotoma in 4 eyes (8.2 %), and paracentral scotoma in 1 eye (2.0 %). After 6 months, central isopter constriction was observed in 18 eyes (36.7 %), diffuse defects in 21 eyes (42.9 %), ceco-central defects in 3 eyes (6.1 %), hemianopia or quadrantanopia in 5 eyes (10.2 %), and central scotoma in 2 eyes (4.1 %). LHON at different stages was characterized by different focal visual field defects: visual field defects in LHON patients within 1 week after onset were mostly central or paracentral scotoma, which was enlarged around the ceco-central defect, or connected to form a blind spot after 3-6 months. Diffuse and central isopter constriction defects were usually developed after 6 months. Damages firstly appeared in papillomacular bundle and gradually expanded outward. These characteristics of visual field defects reported in this study might provide a clinical basis for better diagnosis of LHON.

Their differential diagnosis using computed tomography (CT and magnetic resonance imaging (MRI is difficult because of similarities in morphologic features with other intracranial tumors and meningiomas. Methods: We retrospectively analyzed the clinical data and CT and MRI findings of 32 patients diagnosed with HPCs via histopathology. We evaluated the location, shape, morphologic patterns, density, and signal intensity of the tumors and classified them into four types. Results: The number of tumors analyzed was 32; 29 were supratentorial and three were infratentorial. Eighteen tumors were lobular, while 14 were oval in shape. Further, 28 tumors had cystic areas, and 16 had signal-void vessels. Among the 20 tumors that had been scanned by MRI; eleven showed isointensity, eight slight hyperintensity, and one slight hypointensity on T1-weighted image. Moreover, 12 showed isointensity, and eight showed slight hyperintensity on T2-weighted image and T2-weighted-fluid-attenuated-inversion recovery. Diffusion-weighted images showed isointensity (9/13 or slight hyperintensity (4/13. Of the 15 tumors scanned by contrast-enhanced MRI, one showed poor enhancement; six, moderate enhancement; and eight, intense enhancement. Only one tumor exhibited the “dural tail” sign. Moreover, calcification was observed in just one tumor on CT imaging (1/22. All tumors (5/5 showed intense enhancement on CT angiography, whereas some exhibited dual blood supply (2/5. Conclusion: We conclude that tumors present outside the brain parenchyma, with isointense to slightly intense regions on MRI scans, oval

    Full Text Available Background: Curettage is one of the most common treatment options for benign lytic bone tumors and tumor like lesions. The resultant defect is usually filled. We report our outcome curettage of benign bone tumors and tumor like lesions without filling the cavity. Materials and Methods: We retrospectively studied 42 patients (28 males and 14 females with benign bone tumors who had undergone curettage without grafting or filling of the defect by any other bone graft substitute. The age of the patients ranged from 14 to 66 years. The most common histological diagnosis was that of giant cell tumor followed by simple bone cyst, aneurysamal bone cyst, enchondroma, fibrous dysplasia, chondromyxoid fibroma, and chondroblastoma and giant cell reparative granuloma. Of the 15 giant cell tumors, 4 were radiographic grade 1 lesions, 8 were grade 2 and 3 grade 3. The mean maximum diameter of the cysts was 5.1 (range 1.1-9 cm cm and the mean volume of the lesions was 34.89 cm 3 (range 0.94-194.52 cm 3 . The plain radiographs of the part before and after curettage were reviewed to establish the size of the initial defect and the rate of reconstitution, filling and remodeling of the bone defect. Patients were reviewed every 3 monthly for a minimum period of 2 years. Results: Most of the bone defects completely reconstituted to a normal appearance while the rest filled partially. Two patients had preoperative and three had postoperative fractures. All the fractures healed uneventfully. Local recurrence occurred in three patients with giant cell tumor who were then reoperated. All other patients had unrestricted activities of daily living after surgery. The rate of bone reconstitution, risk of subsequent fracture or the incidence of complications was related to the size of the cyst/tumor at diagnosis. The benign cystic bone lesions with volume greater than approximately 70 cm 3 were found to have higher incidence of complications. Conclusion: This study

    Full Text Available Objective: The conventional management of rhino-orbito-cerebral (ROC mucormycosis includes control of metabolic abnormality, administration of amphotericin B and surgery that spans simple sinus clearance, radical debridement and orbital exenteration. Recent literature includes anecdotal descriptions of successful treatment with conservative management of involved orbits. We evaluated the clinical features and outcome of treatment for the different stages of ROC mucormycosis. Method: In this retrospective case series, 34 case records of patients with a histopathological diagnosis of ROC mucormycosis treated between 1992 and 2000 were reviewed. Three clinical stages and three treatment groups were identified. Patients with limited sino-nasal disease (Clinical stage I underwent sino-nasal debridement (Treatment group A. Patients with limited rhino-orbital disease (Clinical stage II underwent either sino-nasal debridement alone (Treatment group A or orbital exenteration in addition to sino-nasal debridement (Treatment group B. Patients with rhino-orbito-cerebral disease (Clinical stage III did not undergo any surgical procedure (Treatment group C. Thirty-three patients received intravenous amphotericin B. Outcome for each group was measured as "Treatment success" (disease free, stable patient with metabolic abnormality under control and "Treatment failure" (progression of disease with worsening general condition or mortality due to the disease. Results: Uncontrolled diabetes in 30 (88.2% of 34 patients was the commonest underlying disease and 16 (53.3% of 30 diabetics had ketoacidosis. Chronic renal failure (n = 4, hepatic disease (n = 3 and idiopathic thrombocytopenia (n = 1 were the other underlying diseases. Eleven patients had stage I disease, 16 patients had stage II disease and seven patients had stage III disease.

    Full Text Available Background: Two major therapeutic principles can be employed for the treatment of distal femoral fractures: retrograde intramedullary (IM nailing (RN or less invasive stabilization on system (LISS. Both operative stabilizing systems follow the principle of biological osteosynthesis. IM nailing protects the soft-tissue envelope due to its minimally invasive approach and closed reduction techniques better than distal femoral locked plating. The purpose of this study was to evaluate and compare outcome of distal femur fracture stabilization using RN or LISS techniques. Materials and Methods: In a retrospective study from 2003 to 2008, we analyzed 115 patients with distal femur fracture who had been treated by retrograde IM nailing (59 patients or LISS plating (56 patients. In the two cohort groups, mean age was 54 years (17-89 years. Mechanism of injury was high energy impact in 57% (53% RN, 67% LISS and low-energy injury in 43% (47% RN, 33% LISS, respectively. Fractures were classified according to AO classification: there were 52 type A fractures (RN 31, LISS 21 and 63 type C fractures (RN 28, LISS 35; 32% (RN and 56% (LISS were open and 68% (RN and 44% (LISS were closed fractures, respectively. Functional and radiological outcome was assessed. Results: Clinical and radiographic evaluation demonstrated osseous healing within 6 months following RN and following LISS plating in over 90% of patients. However, no statistically significant differences were found for the parameters time to osseous healing, rate of nonunion, and postoperative complications. The following complications were treated: hematoma formation (one patient RN and three patients LISS, superficial infection (one patient RN and three patients LISS, deep infection (2 patients LISS. Additional secondary bone grafting for successful healing 3 months after the primary operation was required in four patients in the RN (7% of patients and six in the LISS group (10% of patients

    A comprehensive retrospective analysis of pesticide metabolites in urine was developed, using liquid chromatography coupled to Orbitrap high-resolution mass spectrometry (UHPLC-HRMS) that includes both post-run target (suspect screening) and non-target screening. An accurate-mass database comprising 263 pesticide metabolites was built and used for the post-run screening analysis. For non-target analysis, a "fragmentation-degradation" relationship strategy was selected. The proposed methodology was applied to 49 real urine samples from pregnant women. In the post-target analysis 26 pesticide metabolites were tentatively identified, 8 of which (2-diethylamino-6-methyl-pyrimidinol; 3-ketocarbofuran; 4,6-dimethoxy-2-pyrimidinamine; 4-hydroxy-2-isporopyl-6-methylpyrimidine; diethyl malate; diethyl maleate; N-(2-Ethyl-6-methylphenyl)-2-hydroxyacetamide and propachlor oxanilic acid ) were confirmed using analytical standards. Likewise, one unknown degradation product, methyl-N-phenylcarbamate was elucidated in the non-target screening. Finally, the real urine samples were grouped according to their origin applying a metabolomic approach.

    Right iliac fossa (RIF) pain is the most common presenting complaint in the general surgical ward. Though there are several causes for the RIF pain, acute appendicitis is the first and common diagnosis. Here we present one of the rare differential diagnoses of RIF pain in a young female patient with one month history of intermittent right lower abdominal pain. Patient's symptoms and clinical findings indicated acute appendicitis, though ultrasonography didn't show any significant abnormality. Through diagnostic laparoscopy we found that there was torsion of anterior abdominal wall parietal peritoneal pedunculated lipoma located in RIF region. The clinical presentation, examination, investigation, laparoscopic findings and further management is presented in this case report.

    The activity of alpha-amylase was measured in isolated granulocytes, serum and urine of 35 patients with acute appendicitis. The measurements were performed before operation and on the 7th day after operation. Slightly increased activity of alpha-amylase was found in the serum and urine of 15 patients. On the 7th day after operation the activity of this enzyme reached normal value. The activity of granulocyte alpha-amylase was elevated in 22 patients. In 2 of them the increased activity still maintained on the 7th day after operation. Positive correlation between the serum and granulocyte alpha-amylase activities was found. These observations allow to conclude that granulocytes are the source of increased alpha-amylase activity in the serum of patients with acute appendicitis.

    Full Text Available Background/Aim. Necrotizing fasciitis (NF is usually an acute infection of superficial fascia with rapid progression in around soft tissue. If not promptly recognized and aggressively treated NF usualy leads to sepsis and multiorgan failure with fatal outcome, thus early diagnosis and prompt surgical treatment are crucial for healing of these patients. The aim of this article was to evaluate the clinical presentation of all patients with acute NF diagnosed and treated in surgical clinics of Clinical Center of Vojvodina, Novi Sad, Serbia. Methods. The medical records of patients treated for acute NF localized on a different parts of the body in Clinical Center of Vojvodina, Novi Sad, Serbia, during a 5- year period (from January 2008 to December 2012 were retrospectively evaluated. This study enrolled patients admitted via Emergency Center of Vojvodina with the diagnosis of acute NF either as the primary diagnosis or with the diagnosis at discharge after surgical treatment. Results. During a 5-year period there were 216 patients with final diagnosis of acute NF. Most of our patients (140 - 64.81% were admitted with the initial diagnosis of cellulitis, abscesses, phlegmons or sepsis. Unfortunately, the clinical symptoms of acute NF were atypical at time of initial examination. Pain and swelling of the affected localization were the most presented bias of symptoms (183 - 84.72%. The majority of our patients were male (164 - 75.92%. Among the 216 patients, the most common pre-existing single factor was drug abuse (39 - 18.05%, followed by obesity (38 - 17.59% and diabetes mellitus (31 - 14.35%. Trauma was most common etiological factor (22 - 10.8% in infected wounds, followed by abdominal (15 - 6.94% and orthopedic (11 - 5.09% surgical intervention. In the present study idiopathic acute NF was diagnosed in 22 (10.18% patients and more than one etiological factor were diagnosed in 20 (9.25% patients. The majority of our patients had type I acute NF

    The purpose of this study was to evaluate postoperative radiotherapy regarding outcome and toxicity in patients with thymic epithelial tumors (TET) after surgery. We retrospectively analyzed medical records of 41 patients with TET treated with postoperative radiotherapy at our institution between 1995 and 2012. The impact of prognostic factors (e.g., Masaoka stage, histological subtype) was investigated and radiation-related toxicity was assessed. Median age was 59.8 years and median follow-up was 61 months. In 24.4 %, TETs were associated with paraneoplastic syndromes. The 5-year overall survival (OS) was 89.5 % and the 5-year disease-free survival (DFS) was 88.9 %. Masaoka stage had a significant impact on OS (p = 0.007). Locally limited stages I + II had a 5-year OS of 100 % compared to 80 % for stage III and 66.7 % for stage IV. The 5-year DFS was excellent with 100 % for both WHO groups A/AB/B1 and B2, respectively, and significantly (p = 0.005) differed from B3/C-staged patients with a 5-year DFS of 63.6 %. Resection status, paraneoplastic association, radiation dose, or tumor size did not influence survival. There were no high-grade acute or late side effects caused by radiotherapy. Masaoka stage has a significant impact on OS as WHO type has on DFS in patients with TETs after surgery and adjuvant irradiation. Postoperative radiotherapy with doses around 50 Gy is safe and not likely to cause high-grade toxicity. Further prospective trials are necessary to separate patient subgroups that benefit from radiotherapy from those that do not. (orig.)

    Full Text Available Xanthogranulomatous inflammation is common in interval appendectomy specimens in adults, but it is unusual in children. Histopathologic specimens of interval appendectomy, within an 8-year period, were reevaluated to assess the true incidence. A computer search of the hospital database of all appendectomies was performed between January 2008 and June 2015 to identify all interval appendectomy cases. A total of 2694 patients underwent appendectomies. Of these, 13 were interval appendectomies. After pathologic evaluation, 2 (15.4% of the specimens were reported as xanthogranulomatous appendicitis (XA. Histopathologic examination of these interval appendectomy specimens, granulomas (59%, xanthogranulomatous inflammation (36% and Crohn-like changes (50% were common in adults. However, XA is a particularly rare clinical entity among children. Two cases of XA were reported in children in the English literature. One was a 12-year old boy that underwent interval appendectomy 6 weeks after an episode of acute appendicitis. The other was an 11-year old boy with acute (non-interval appendicitis, but the complete blood count was suggestive of an acute suppurative inflammation. These two cases are the 3rd and 4th cases of XA reported in children in the English literature, and both were managed by interval appendectomy. Thus, XA may be encountered in interval appendectomy specimens and association with IBD has to be ruled out.

    INTRODUCTION Atypical presentations of appendix have been reported including backache, left lower quadrant pain and groin pain from a strangulated femoral hernia containing the appendix. We report a case presenting an epigastric pain that was diagnosed after computed tomography as a perforated appendicitis on intestinal malrotation. PRESENTATION OF CASE A 27-year-old man was admitted with a three-day history of epigastric pain. Physical examination revealed tenderness and defense on palpation of epigastric region. There was a left subcostal incision with the history of diaphragmatic hernia repair when the patient was 3 days old. He had an intestinal malrotation with the cecum fixed at the epigastric region and the inflamed appendix extending beside the left lobe of liver. DISCUSSION While appendicitis is the most common abdominal disease requiring surgical intervention seen in the emergency room setting, intestinal malrotation is relatively uncommon. When patients with asymptomatic undiagnosed gastrointestinal malrotation clinically present with abdominal pain, accurate diagnosis and definitive therapy may be delayed, possibly increasing the risk of morbidity and mortality. CONCLUSION Atypical presentations of acute appendicitis should be kept in mind in patients with abdominal pain in emergency room especially in patients with previous childhood operation for diaphragmatic hernia.

    We have performed a retrospective analysis of all patients with extragastric mucosa-associated lymphoid tissue (MALT) lymphoma treated at our institution to compare the efficacy of first-line therapeutic modalities including surgery, radiation, systemic therapy, and antibiotics. One hundred eighty-five patients with extragastric MALT lymphoma with a median age of 63 (interquartile range (IQR) 50-74) years and a median follow-up time of 49 (IQR 18-103) months were retrospectively analyzed. Time to progression and time to next therapy were used as surrogate endpoints for efficacy. Patients having either surgery (100 %), chemo/immunotherapy (85.5 %), or radiation (80 %) had significantly (p = 0.01) higher response rates than patients treated with antibiotics (33.3 %). Patients who were irradiated had significantly more progressive disease, but also the longest follow-up time. Stage, elevated LDH, anemia, elevated beta-2 microglobulin, plasmacytic differentiation, monoclonal gammopathy, or autoimmune disease did not influence the rate of disease progression nor did complete remission or partial remission from initial therapy influence time to and rate of progression. There was no significant difference in the median time to progression (p = 0.141), but the estimated time to progression (p = 0.023) as well as the estimated time to next therapy (p = 0.021) was significantly different among the various cohorts favoring surgery, chemo/immunotherapy, and radiation. Our results suggest extragastric MALT lymphoma as a potential systemic disease irrespective of initial stage. Radiation, surgery, and chemo/immunotherapy seem to be equally effective in achieving remissions and prolonged progression free survivals, but a curative potential is questionable. Localized MALT lymphomas affecting the thyroid gland or the lungs have excellent long-term progression-free survivals with surgical treatment only.

    Full Text Available Statement of Problem: Information about etiology and incidence of maxillofacial trauma is important for prevention and appropriate treatments of such injuries. Purpose: The purpose of this retrospective study was to conduct an analysis of maxillofacial injuries transferred and/or referred to the department of maxillofacial Surgery at Chamran emergency hospital, Shiraz, over a 6-year-period with special reference to age, gender, occupation, date, type, site, etiology and clinical management. Materials and Method: The data for this study were collected and reviewed retrospec-tively from the records and radiographs of 768 patients who were treated for maxillofacial trauma in the department of maxillofacial surgery at the Shiraz Chamran Emergency Hospital, Iran, between 2004 and 2010. Results: A total of 730 of the subjects were the patients with fractures of the facial skeleton. The mean age was 26.6± 12.6 years, ranging from 2 to 81 years. Traffic accident was the most frequent etiological factor of maxillofacial fractures irrespective of gender (69.9% for men and 54.2% for women, whereas the second most frequent cause of injuries was falling down (9.8% for men and 21.5% for women .The other etiologies were assault (5.2%, sport related injuries (1.3% and firearm injuries (1%. Regarding the head injuries in patients with maxillofacial fractures, brain contusion was seen in 227(29.6% patients and 13.5% of patients had lacerations in the facial soft tissue. The monthly distribution peaked in October, with 81 cases (10.5%, which seems to have been due to schools opening. The next highest incidence was in December, with 80 cases (10.4%, probably because of the changing weather's effect on road traffic. Conclusion: Isolated mandibular fracture due to the road traffic accident was the most common type of maxillofacial injuries in the city of Shiraz.

    The purpose of this study was to examine the allometric analyses of marbofloxacin, moxifloxacin, danofloxacin and difloxacin using pharmacokinetic data from the literature. The parameters of interest (half-life, clearance and volume of distribution) were correlated across species as a function of body weight using an allometric approach (Y = aWb). Results of the allometric analysis indicated similarity between clearance and volume of distribution as they relate to body weight for all drugs. The elimination half-life was independent of body mass for all fluoroquinolones except moxifloxacin. Results of the analysis suggest that allometric scaling can be used as a tool for predicting pharmacokinetic parameters for fluoroquinolones.

    Full Text Available Objective: To evaluate the necessity of the non contrast-enhanced phase in abdominal computed tomography scans. Materials and Methods: A retrospective, cross-sectional, observational study was developed, evaluating 244 consecutive abdominal computed tomography scans both with and without contrast injection. Initially, the contrast-enhanced images were analyzed (first analysis. Subsequently, the observers had access to the non-contrast-enhanced images for a second analysis. The primary and secondary diagnoses were established as a function of the clinical indications for each study (such as tumor staging, acute abdomen, investigation for abdominal collection and hepatocellular carcinoma, among others. Finally, the changes in the diagnoses resulting from the addition of the non-contrast-enhanced phase were evaluated. Results: Only one (0.4%; p > 0.999; non-statistically significant out of the 244 reviewed cases had the diagnosis changed after the reading of non-contrast-enhanced images. As the secondary diagnoses are considered, 35 (14% cases presented changes after the second analysis, as follows: nephrolithiasis (10%, steatosis (3%, adrenal nodule (0.7% and cholelithiasis (0.3%. Conclusion: For the clinical indications of tumor staging, acute abdomen, investigation of abdominal collections and hepatocellular carcinoma, the non-contrast-enhanced phase can be excluded from abdominal computed tomography studies with no significant impact on the diagnosis.

    Discussion Australian HI publications in PubMed increased consistently throughout the period 1970-2005, which is on a par with world trends in HI publications. In Australia, most HI publications are in general medical journals. Lack of consistency in author names and failure to include the country name and even the state are the main obstacles to PubMed bibliometric analysis.

    General surgeons are often asked to evaluate acute abdominal pain which has an expanded differential diagnosis in women of childbearing age. Acute appendicitis accounts for many surgical emergencies as a common cause of nongynecologic pelvic pain. In some rare instances, acute appendicitis has been shown to occur simultaneously with a variety of gynecologic diseases. We report a case of concurrent acute appendicitis and ruptured ovarian endometrioma. PMID:28097032

    Full Text Available Abstract Background The aim of this study is to develop a simple and reliable hybrid decision support model by combining statistical analysis and decision tree algorithms to ensure high accuracy of early diagnosis in patients with suspected acute appendicitis and to identify useful decision rules. Methods We enrolled 326 patients who attended an emergency medical center complaining mainly of acute abdominal pain. Statistical analysis approaches were used as a feature selection process in the design of decision support models, including the Chi-square test, Fisher's exact test, the Mann-Whitney U-test (p Results Of 55 variables, two subsets were found to be indispensable for early diagnostic knowledge discovery in acute appendicitis. The two subsets were as follows: (1 lymphocytes, urine glucose, total bilirubin, total amylase, chloride, red blood cell, neutrophils, eosinophils, white blood cell, complaints, basophils, glucose, monocytes, activated partial thromboplastin time, urine ketone, and direct bilirubin in the univariate analysis-based model; and (2 neutrophils, complaints, total bilirubin, urine glucose, and lipase in the multivariate analysis-based model. The experimental results showed that the model with univariate analysis (80.2%, 82.4%, 78.3%, 76.8%, 83.5%, and 80.3% outperformed models using multivariate analysis (71.6%, 69.3%, 73.7%, 69.7%, 73.3%, and 71.5% with entry and removal criteria of 0.01 and 0.05; 73.5%, 66.0%, 80.0%, 74.3%, 72.9%, and 73.0% with entry and removal criteria of 0.05 and 0.10 in terms of accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and area under ROC curve, during a 10-fold cross validation. A statistically significant difference was detected in the pairwise comparison of ROC curves (p p Conclusions The decision model developed in this study can be applied as an aid in the initial decision making of clinicians to increase vigilance in cases of suspected acute

    The AM Short Course on The Modern Era Retrospective-analysis for Research and Applications (MERRA) data and accessibility will be held on January 11, 2009 preceding the 89th Annual Meeting in Phoenix, Arizona. Preliminary programs, registration, hotel, and general information will be posted on the AMS Web site in mid-September 2008. Retrospective-analyses (or reanalyses) have been established as an important tool in weather and climate research over the last decade. As computer power increases, the data assimilation and modeling systems improve and become more advanced, the input data quality increases and so reanalyses become more reliable. In 2008, NASA Global Modeling and Assimilation Office began producing a new reanalysis called the Modem Era Retrospective-analysis for Research and Applications (MERRA). The initial data from the reanalysis has been made available to the community and should be complete through 30 years (1979-present) by Fall of 2009. MERRA has taken advantage of the advancement of computing resources to provide users more data than previously available. The native spatial resolution is nominally 1/2 degrees and the surface two dimensional data are one hourly frequency. In addition to the meteorological analysis data, complete mass, energy and momentum budget data and also stratospheric data are provided. The eventual data holdings will exceed 150Tb. In order to facilitate user accessibility to the data, it will be stored in online hard drives (not tape storage) and available through several portals. Subsetting tools will also be available to allow users to tailor their data requests. The goals of this short course are to provide hands on users of reanalyses instruction on MERRA systems and also interactive experience with the online data and access tools. The course is intended for students and research scientists who will be actively interested in accessing and applying MERRA data in their weather, climate or applications work. The course has

    Willard Day's contributions to radical behaviorism are grouped under three headings: (a) an emphasis on the distinction between radical and methodological behaviorism; (b) an emphasis on the interpretation, rather than the prediction and control, of behavior; and (c) an emphasis on the analysis of verbal behavior as a natural, ongoing phenomenon. The paper suggests that the contributions above are listed in ascending order of significance. PMID:22477632

    This study aimed to elucidate the demographic and sleeping environmental factors associated with sudden infant death syndrome (SIDS) in Korea. The autopsy reports of all SIDS cases reported to the National Forensic Service and Seoul National University College of Medicine between 1996 and 2008 were reviewed for data collection and analysis to identify the risk factors for SIDS. Analysis of the 355 SIDS cases reported within the study period revealed that of the 168 (47.3%) cases for which sleeping position before death had been reported, 75 (44.7%) cases had occurred after placement in prone or side position. Of the 204 (57.5%) cases for which bed-sharing situation had been reported, 121 (59.3%) deaths had occurred during bed-sharing, of which 54 (44.6%) infants were under 3 months of age, a significantly younger age than that of the non-bed-sharing cases (P = 0.0279). Analysis of the results indicated no tendency toward an increase or decrease in the use of a prone or side position. Rather, there was a statistically significant increasing trend for bed-sharing over the study period (OR, 1.087; 95% CI, 1.004-1.177; P = 0.04). These findings indicate the need for nationwide educational programs promoting a safe sleeping environment to enhance SIDS prevention.

    Stump appendicitis is an acute inflammation of the residual appendix and one of the rare complications after appendectomy. Paying attention to the possibility of stump appendicitis in patients with right lower abdominal pain after appendectomy can prevent the delay of diagnosis and treatment. In patients with stump appendicitis,CT scan not only assists in making an accurate preoperative diagnosis but also excludes other etiologies. We report a 47-year old man with preoperatively diagnosed stump appendicitis by CT, who underwent an open appendectomy 20 years ago.

    To evaluate the usefulness of high-resolution ultrasonography (US) for the differentiation of acute perforated appendicitis from non-perforated appendicitis. The high-resolution US features in 96 patients (49 males, 47 females; mean age, 33.8 years; age range, 4-80 years) with pathologically proven acute appendicitis were evaluated. The following US findings were evaluated for differentiation of acute perforated appendicitis from non-perforated appendicitis: circumferential loss of the echogenic submucosal layer, periappendiceal fluid collection, disruption of the serosal layer, asymmetrical wall thickening, maximum overall diameter > 10.5 mm, and the presence of appendicoliths. The sensitivity and specificity of the US features in the diagnosis of acute perforated appendicitis were calculated. All of the US findings, except for appendicoliths, were significantly more common in the acute perforated appendicitis group (p < 0.001). The sensitivity of circumferential loss of the echogenic submucosal layer, periappendiceal fluid collection, disruption of the serosal layer, asymmetrical wall thickening, maximum overall diameter > 10.5 mm, and the presence of appendicoliths was 85.4, 73.2, 68.3, 70.7, 80.5, and 36.6%, respectively, while the specificity was 65.5, 89.1, 96.4, 98.2, 81.8, and 80.0%, respectively. High-resolution US was found to be useful for differentiating acute perforated appendicitis from non-perforated appendicitis.

    Objective: The aim of this study was to identify prognostic factors and imply the appropriate management for lo-cal recurrent osteosarcoma. Methods: The clinical records of 60 patients with local recurrence osteosarcoma were reviewed between January 2002 and December 2010. The mean followed-up time for these patients was 49.1 months (range 13 to 143 months). The factors of age, gender, tumor site, tumor size, surgical procedure, neoadjuvant chemotherapy, frequency of primary postoperative adjuvant chemotherapy, lung metastasis, metastasis of other sites (except for lung) and treatment after local recurrence were selected as the measurements for this analysis. Kaplan-Meier method was used to measure the overall survival and post-recurrence survival. The univariate analysis was used to determine the prognostic factors related with survival by Log-rank test. The COX proportional-hazard regression model was used to analyze the correlation between the prognostic factor and the survival. Results: The median post-recurrence survival and overall survival of 60 patients were 32 months (95% confidence interval: 16.2-47.8) and 55 months (95% confidence interval: 39.3–70.7) respectively. The 2- and 3-year cumulative survival rates were 81.7% and 55.4%, respectively. The Log-rank univariate analysis showed that age, gender, tumor size, metastasis of other sites (except for lung) and treatment after local recurrence were associated with the prognosis of osteosarcoma with local recurrence (P 0.05). Conclusion: The independent prognostic factors for local recurrent osteosarcoma were the metastasis of other site (except for lung) and the treatment after local recurrence. The aggressive surgical treatment for local recurrence and distant metastasis could effectively improve the survival of local recurrent osteosarcoma.

    AIM To determine if our health system’s integrated model reflects sustained virologic response (SVR) outcomes similar to those in clinical trial data, maximizes adherence, and averts drug interactions. METHODS Subjects with chronic hepatitis C had their medical records reviewed from November 1st, 2014 through March 1st, 2016. Patients eligible for treatment were entered into an integrated care model therapy algorithm. The primary outcome was SVR12 based on intention to treat (ITT) analysis. Inclusion criteria consisted of both treatment naïve and experienced patients over the age of 18 who were at least twelve weeks post-therapy completion with any genotype (GT) or METAVIR score. Secondary outcomes included adherence, adverse events, and number of drug interaction interventions. RESULTS At the time of analysis, 133 patients had reached twelve weeks post therapy with ITT. In the ITT analysis 70 patients were GT 1a, 26 GT 1b, 23 could not be differentiated between GT 1a or 1b, 8 GT 2, 4 GT 3, and 2 patients with multiple genotypes. The ITT treatment regimens consisted of 97 sofosbuvir (SOF)/ledipasvir (LDV), 8 SOF/LDV and ribavirin (RBV), 7 SOF and Simeprevir (SMV), 6 3D and RBV, 1 3D, 11 SOF and RBV, and 1 SOF, peg interferon alpha, and RBV. The overall SVR12 rate was 93% in the ITT analysis with a total of 6 patients relapsing. In patients with cirrhosis, 89% obtained SVR12. All 33 patients who were previous treatment failures achieved SVR12. Drug-drug interactions were identified in 56.4% of our patient population, 69 of which required interventions made by the pharmacist. The most common side effects were fatigue (41.4%), headache (28.6%), nausea (18.1%), and diarrhea (8.3%). No serious adverse effects were reported. CONCLUSION Dean Health System’s integrated care model successfully managed patients being treated for hepatitis C virus (HCV). The integrated care model demonstrates high SVR rates amongst patients with different levels of fibrosis, genotypes

    2013-10-01

    The physician's need for medical information updates has been studied extensively in recent years but the point of view of the pharmaceutical industry on this need has rarely been considered. This paper reports the results of a retrospective analysis of the medical information service provided to Italian physicians by an important pharmaceutical company, Novartis Pharma, from 2004 to 2012. The results confirm clinicians' appreciation of a service that gives them access to tailored scientific documentation and the number of requests made to the network of medical representatives has been rising steadily, peaking whenever new drugs become available to physicians. The analysis confirms what -other international studies have ascertained, that most queries are about how to use the drugs and what their properties are. The results highlight some differences between different medical specialties: for example, proportionally, neurologists seem to be the most curious. This, as well as other interesting snippets, is worth further exploration. Despite its limits in terms of representativeness, what comes out of the study is the existence of an real unmet need for information by healthcare institutions and that the support offered by the pharmaceutical industry could be invaluable; its role could go well beyond that of a mere supplier to National Healthcare Systems, to that of being recognised as an active partner the process of ensuring balanced and evidence-based information. At the same time, closer appraisal of clinicians' needs could help the pharma industries to improve their communication and educational strategies in presenting their latest clinical research and their own products.

    In patients treated with allogeneic stem cell transplantation (SCT) for malignant disease who suffer from a relapse after the transplantation, the role of second allogeneic SCT is often uncertain. In a retrospective analysis, 2632 second allogeneic transplantations carried out for a relapse after the first transplantation were analyzed to define indications and identify predictive factors. Fifteen percent of the patients remained relapse-free until 5 years after the second SCT. Patients with CML had a better survival than patients with other diseases. In a multivariate analysis, factors associated with better survival were low disease burden, longer remission duration after the first transplantation, longer interval between the transplantations, younger age, absence of grade II-IV acute GvHD or chronic GvHD after the first transplantation, and later year of transplantation. The European Society for Blood and Marrow Transplantation risk score predicted the outcome. Using the same donor as in the first transplantation vs another donor had no predictive value for survival. Sibling donor was a favorable predictive factor. In conclusion, second allogeneic SCT offers a reasonable option especially for young patients with a long remission after the first transplantation and a low disease burden. The present findings do not support the usefulness of changing the donor for the second transplantation.

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

  19. An Unprecedented High Incidence of Leptospirosis in Futuna, South Pacific, 2004 - 2014, Evidenced by Retrospective Analysis of Surveillance Data.

    Directory of Open Access Journals (Sweden)

    Denis Massenet

    Full Text Available Futuna is a small Polynesian island in the South Pacific with a population of 3,612 in 2013. The first human leptospirosis case was confirmed in 1997. Active surveillance started in 2004. Cases were confirmed by PCR or real time PCR, or by serology using MAT or a combination of IgM-ELISA and MAT. A retrospective analysis of surveillance data shows that the disease was endemic with a mean annual incidence of 844 cases per 100,000 over an 11-year period from 2004 to 2014. An epidemic peak as high as 1,945 cases per 100,000 occurred in 2008. Serogroup Australis was predominant until 2007, Icterohaemorrhagiae was dominant afterwards. Cluster analysis revealed different hot spots over time. Lifestyle habits, such as walking barefoot in irrigated taro fields or pig pens probably contributed to contamination from the swine and rodent reservoirs to humans. Severe forms were rare, and the case fatality rate was 0.5%. The medical community and general population were aware of leptospirosis and rapid treatment with amoxycillin was the main treatment, probably contributing to this low fatality rate.

    In 2005, the Belgian authorities reported a Listeria monocytogenes contamination episode in cheese made from raw goat's milk. The presence of an asymptomatic shedder goat in the herd caused this contamination. On the basis of data collected at the time of the episode, a retrospective study was performed using an exposure assessment model covering the production chain from the milking of goats up to delivery of cheese to the market. Predictive microbiology models were used to simulate the growth of L. monocytogenes during the cheese process in relation with temperature, pH, and water activity. The model showed significant growth of L. monocytogenes during chilling and storage of the milk collected the day before the cheese production (median increase of 2.2 log CFU/ml) and during the addition of starter and rennet to milk (median increase of 1.2 log CFU/ml). The L. monocytogenes concentration in the fresh unripened cheese was estimated to be 3.8 log CFU/g (median). This result is consistent with the number of L. monocytogenes in the fresh cheese (3.6 log CFU/g) reported during the cheese contamination episode. A variance-based method sensitivity analysis identified the most important factors impacting the cheese contamination, and a scenario analysis then evaluated several options for risk mitigation. Thus, by using quantitative microbial risk assessment tools, this study provides reliable information to identify and control critical steps in a local production chain of cheese made from raw goat's milk.

This study utilized a benefit-cost analysis to determine if this ORV programme was economically worthwhile. Between 1979 and 1989, prior to ORV baiting, the average annual human post-exposure treatments, positive red fox rabies diagnostic tests and indemnity payments for livestock lost to rabies were 2248, 1861 and $246,809, respectively. After baiting, from 1990 to 2000, a 35%, 66% and 41% decrease in post-exposure treatments, animal rabies tests and indemnity payments was observed, respectively. These reductions were viewed as benefits of the ORV programme, whereas total costs were those associated with ORV baiting. Multiple techniques were used to estimate four different benefit streams and the total estimated benefits ranged from $35,486,316 to $98,413,217. The annual mean ORV programme cost was $6,447,720, with total programme costs of $77,372,637. The average benefit-cost ratios over the analysis period were .49, 1.06, 1.27 and 1.36, indicating overall programme efficiency in three of the four conservative scenarios.

    With the growth of the patient safety movement and development of methods to measure workforce health and success have come multiple modes of assessing healthcare worker opinions and attitudes about work and the workplace. Safety culture, a group-level measure of patient safety-related norms and behaviours, has been proposed to influence a variety of patient safety outcomes. Employee engagement, conceptualised as a positive, work-related mindset including feelings of vigour, dedication and absorption in one's work, has also demonstrated an association with a number of important worker outcomes in healthcare. To date, the relationship between responses to these two commonly used measures has been poorly characterised. Our study used secondary data analysis to assess the relationship between safety culture and employee engagement over time in a sample of >50 inpatient hospital units in a large US academic health system. With >2000 respondents in each of three time periods assessed, we found moderate to strong positive correlations (r=0.43-0.69) between employee engagement and four Safety Attitudes Questionnaire domains. Independent collection of these two assessments may have limited our analysis in that minimally different inclusion criteria resulted in some differences in the total respondents to the two instruments. Our findings, nevertheless, suggest a key area in which healthcare quality improvement efforts might be streamlined.

    Full Text Available Assisted reproductive technology (ART has grown by leaps and bounds in the last few years. India has one of the highest growths in the ART centers and the number of ART cycles performed every year. Very soon India will be the leader in the world of ART in terms of a number of cycles. With the advances of technology and availability of techniques even in tier II and tier III cities our country, the results still vary dramatically. There is no standardization of protocols and reporting is very inadequate. Furthermore, there are only ART guidelines and no law still exists. Our first and the biggest challenge is to document the tremendous work being done in India and on the basis of analysis of this work, a proper registry can be made and guidance given to all on standardization and improvement. This is the 8 th edition of National ART Registry of India being presented and analyzed.

    The medical records of 468 horses that underwent 490 exploratory laparotomies for the correction of gastrointestinal diseases were reviewed to search for differences between Andalusian horses and other breeds. The seasonal distribution of surgical colics and their outcome and complications were also investigated. Bivariant analysis was used to compare the horses' age, gender and breed with the type of surgery, the bowel affected and the type of colic, and all these variables were compared in relation to euthanasia during surgery, complications, short-term survival and seasonal distribution. A total of 405 horses survived the surgery and 329 were discharged from the hospital. Horses less than one year old had better short-term survival than older horses. Andalusian horses suffered more inguinal hernias than the other breeds and were more prone to suffer laminitis as a complication. Colic surgery and inguinal hernias were also more common in the summer.

    Thermal conductivity data acquired previously for the establishment of Standard Reference Material (SRM) 1450, Fibrous Glass Board, as well as subsequent renewals 1450a, 1450b, 1450c, and 1450d, are re-analyzed collectively and as individual data sets. Additional data sets for proto-1450 material lots are also included in the analysis. The data cover 36 years of activity by the National Institute of Standards and Technology (NIST) in developing and providing thermal insulation SRMs, specifically high-density molded fibrous-glass board, to the public. Collectively, the data sets cover two nominal thicknesses of 13 mm and 25 mm, bulk densities from 60 kg·m(-3) to 180 kg·m(-3), and mean temperatures from 100 K to 340 K. The analysis repetitively fits six models to the individual data sets. The most general form of the nested set of multilinear models used is given in the following equation: [Formula: see text]where λ(ρ,T) is the predicted thermal conductivity (W·m(-1)·K(-1)), ρ is the bulk density (kg·m(-3)), T is the mean temperature (K) and ai (for i = 1, 2, … 6) are the regression coefficients. The least squares fit results for each model across all data sets are analyzed using both graphical and analytic techniques. The prevailing generic model for the majority of data sets is the bilinear model in ρ and T. [Formula: see text] One data set supports the inclusion of a cubic temperature term and two data sets with low-temperature data support the inclusion of an exponential term in T to improve the model predictions. Physical interpretations of the model function terms are described. Recommendations for future renewals of SRM 1450 are provided. An Addendum provides historical background on the origin of this SRM and the influence of the SRM on external measurement programs.

    Full Text Available Abstract Background The objective of this research is to quantify the association between direct medical costs attributable to type 2 diabetes and level of glycemic control. Methods A longitudinal analysis using a large health plan administrative database was performed. The index date was defined as the first date of diabetes diagnosis and individuals had to have at least two HbA1c values post index date in order to be included in the analyses. A total of 10,780 individuals were included in the analyses. Individuals were stratified into groups of good (N = 6,069, fair (N = 3,586, and poor (N = 1,125 glycemic control based upon mean HbA1c values across the study period. Differences between HbA1c groups were analyzed using a generalized linear model (GLM, with differences between groups tested by utilizing z-statistics. The analyses allowed a wide range of factors to affect costs. Results 42.1% of those treated only with oral agents, 66.1% of those treated with oral agents and insulin, and 57.2% of those treated with insulin alone were found to have suboptimal control (defined as fair or poor throughout the study period (average duration of follow-up was 2.95 years. Results show that direct medical costs attributable to type 2 diabetes were 16% lower for individuals with good glycemic control than for those with fair control ($1,505 vs. $1,801, p Conclusion Almost half (44% of all patients diagnosed with type 2 diabetes are at sub-optimal glycemic control. Evidence from this analysis indicates that the direct medical costs of treating type 2 diabetes are significantly higher for individuals who have fair or poor glycemic control than for those who have good glycemic control. Patients under fair control account for a greater proportion of the cost burden associated with antidiabetic prescription drugs.

    Introduction: The aim of this study was to define and characterise differences in the level of obstetric care provided to immigrant and German women. Materials and Methods: An analysis of the Virchow Hospitalʼs birth registers was conducted for the years 1974, 1984 and 1994. The study population of 5445 patients was grouped according to ancestry/family origin on the basis of a name analysis, and subsequently also according to parity (primiparous or multiparous). On name analysis 2741 women were defined as German, 1598 were grouped as women of Turkish origin and 810 as immigrants of other origin. χ2 tests and Fisherʼs exact test were used for significance testing (significance level p episiotomy, higher grade perineal tears and severe postpartum haemorrhage did not differ between the groups. There were however significant differences in the use of uterine stimulants, analgesics in labour and both local and regional anaesthesia, with women of Turkish origin and other immigrants receiving anaesthesia less, but oxytocin more often. Rooming-in was more common among German primipara and multipara from 1984 onwards. Discussion: This retrospective analysis of three historical birth cohorts showed significant differences in perinatal care between German and immigrant women, presumably reflecting deficits in care. It seems remarkable that this trend has not changed over a time span of three decades despite a continuous increase in immigration and acculturation. A “research paradox”, however, remains: Despite these increasing rates, there are no current or older, prospective or systematic studies of obstetric care in immigrants. PMID:27904165

    AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically con- firmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clinical or pathologic tumor, node and metastasis stage of the primary gastric cancer was Ⅳ in 38 patients (70%).The median interval from diagnosis of the primary malignancy to the diagnosis of LMC was 6.3 mo, ranging between 0 and 73.1 mo. Of the initial endoscopic findings for the 45 available patients, 23 (51%) of the patients were Bormann type Ⅲ and 15 (33%) patients were Bormann type Ⅳ. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas.Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patientsprimarily methotrexate alone (61%), but also in combination with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients,and concomitant chemotherapy to seven patients. Seventeen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin,IT chemotherapy, and cytological negative conversion showed superior survival duration ( P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of

    Objective To explore the clinical characteristics of liver hemangioma rupture bleeding, and evaluate its differ-ential diagnosis. Methods Retrospectively analysis of the clinical data of a case of multiple liver hemangioma rupture hemorrhage misdiagnosed as acute appendicitis was made. Results A patient with lower abdominal pain for 20 hours before admission was pri-marily diagnosed as having acute appendicitis, and underwent an emergency laparotomy. During the operation, no abnormal appen-dix was found, but a mass in liver with burst bleeding was found and the liver surface was full of millet qualitative hard nodules. Be-cause of impossible determination on the nature of the tumor, the patient was given local hemostasis therapy, and abdominal cavity was washed, then drainage tube was placed at the same time, some tissues surrounding bleeding mass was removed, and no active bleeding before abdominal closing was observed. Postoperative pathologic result of liver mass showed degeneration of liver cells, with cellulose and inflammatory cells, and reinforced CT scanning confirmed liver hemangioma rupture bleeding, but to define the cause of bleeding, a followed enquiry of history and related examinations were made before systemic lupus erythematosus (active phase) was confirmed. Gamma globulin and Methylprednisolone treatment were given and the patient was discharged after improvement. Conclusion Because of the particular position, patients with liver hemangioma (right liver lobe) rupture hemorrhage usually have atypical clinical symptoms and signs, which may be related to systemic lupus erythematosus and mistaken as acute appendicitis.%目的:探讨肝血管瘤破裂出血的临床特点及鉴别诊断要点。方法对肝多发血管瘤破裂出血误诊为急性阑尾炎1例的临床资料进行回顾性分析。结果本例因右下腹痛20 h急诊入院,按急性阑尾炎行剖腹探查术。术中探查示:阑尾未见异常,肝

    Full Text Available Background. Data on the economic impact of Lyme borreliosis (LB on European health care systems is scarce. This project focused on the epidemiology and costs for laboratory testing in LB patients in Germany. Materials and Methods. We performed a sentinel analysis of epidemiological and medicoeconomic data for 2007 and 2008. Data was provided by a German statutory health insurance (DAK company covering approx. 6.04 million members. In addition, the quality of diagnostic testing for LB in Germany was studied. Results. In 2007 and 2008, the incident diagnosis LB was coded on average for 15,742 out of 6.04 million insured members (0.26%. 20,986 EIAs and 12,558 immunoblots were ordered annually for these patients. For all insured members in the outpatient sector, a total of 174,820 EIAs and 52,280 immunoblots were reimbursed annually to health care providers (cost: 2,600,850€. For Germany, the overall expected cost is estimated at 51,215,105€. However, proficiency testing data questioned test quality and standardization of diagnostic assays used. Conclusion. Findings from this study suggest ongoing issues related to care for LB and may help to improve future LB disease management.

    Central venous catheter (CVC) placement is associated with increased risk of thrombosis in the paediatric population, particularly in relation to the type of catheter and the manner of its insertion. Here, we investigate risk factors associated with CVC-related thrombosis in children, with particular emphasis on positioning of the catheter tip. Patients aged 0-18 who underwent at least one CVC placement from 2008 to 2013 at a single centre with a subsequent follow-up echocardiogram were included for a total of 104 patients and 147 lines. Data on clinical and catheter-related risk factors were collected from patient charts. Statistical analysis using Pearson's χ tests, independent samples t-test, and odds ratios were used to assess potential risk factors for thrombosis. Neither insertion site (subclavian vein or otherwise), left- vs. right-sided insertion, nor catheter type were significant risk factors for thrombosis. There were no thrombotic events reported at the superior vena cava (SVC)-right atrium junction and no significant differences in thrombotic risk with initial tip placement in the SVC-right atrium junction vs. the SVC, right atrium, or inferior vena cava. Acute lymphoblastic leukaemia was a major clinical risk factor for thrombosis. Tip movement was common and may have been an important factor in the development of CVC-related thrombi. Prospective studies can yield insight into the role of follow-up imaging in the prevention of catheter-related thrombosis in children.

    Results: The initial symptoms varied considerably, with nausea and vomiting (13/56, 23% being the most common. Liver-function indexes were remarkable, including elevated levels of serum alanine aminotransferase (262.16 ± 281.71 U/L, aspartate aminotransferase (260.98 ± 237.91 U/L, lactic dehydrogenase (1011.76 ± 530.34 U/L, and direct bilirubin (85.59 ± 90.02 μmol/L. Coagulation disorders were indicated by abnormal levels of fibrinogen (245.95 ± 186.11 mg/dL, D-dimer (2.46 ± 4.01 mg/L, and fibrin degradation products (43.62 ± 48.71 mg/L. The main maternal complications were hypoproteinemia (75%, coagulopathy (54%, and acute renal failure (39%. Multivariate logistic regression analysis identified prothrombin time (PT; odds ratio [OR] = 1.558, 95% confidence interval [CI] =1.248–1.946, PORCIP= 0.009 as risk factors. The perinatal infant death rate was related to gestational age at delivery (ORCI PORCI PORCI PConclusions: Nausea and vomiting may be the most common symptoms of AFLP. Indexes of liver dysfunction and coagulation disorders should also be considered. PT and INR are risk factors for fatal complications in patients with AFLP, and perinatal mortality is linked to the level of fibrin degradation products. Timely delivery is crucial to controlling the development of AFLP.

    Background. Obesity impacts utilization of healthcare resources. The goal of this study was to measure the relationship between increasing body mass index (BMI) in patients undergoing total hip arthroplasty (THA) with different components of operating room (OR) time. Methods. The Stanford Translational Research Integrated Database Environment (STRIDE) was utilized to identify all ASA PS 2 or 3 patients who underwent primary THA at Stanford Medical Center from February 1, 2008 through January 1, 2013. Patients were divided into five groups based on the BMI weight classification. Regression analysis was used to quantify relationships between BMI and the different components of total OR time. Results. 1,332 patients were included in the study. There were no statistically significant differences in age, gender, height, and ASA PS classification between the BMI groups. Normal-weight patients had a total OR time of 138.9 min compared 167.9 min (P 35 kg/m(2) each incremental BMI unit increase was associated with greater incremental total OR time increases. Conclusion. Morbidly obese patients required significantly more total OR time than normal-weight patients undergoing a THA procedure. This increase in time is relevant when scheduling obese patients for surgery and has an important impact on health resource utilization.
