    Full Text Available Abstract Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

    Full Text Available INTRODUCTION: Friedreich's ataxia is a neurodegenerative disorder whose clinical diagnostic criteria for typical cases basically include: a early age of onset (< 20 or 25 years, b autosomal recessive inheritance, c progressive ataxia of limbs and gait, and d absence of lower limb tendon reflexes. METHODS: We studied the frequency and the size of expanded GAA and their influence on neurologic findings, age at onset, and disease progression in 25 Brazilian patients with clinical diagnosis of Friedreich's ataxia - 19 typical and 6 atypical - using a long-range PCR test. RESULTS: Abnormalities in cerebellar signs, in electrocardiography, and pes cavus occurred more frequently in typical cases; however, plantar response and speech were more frequently normal in this group when the both typical and atypical cases were compared. Homozygous GAA expansion repeats were detected in 17 cases (68% - all typical cases. In 8 patients (32% (6 atypical and 2 typical, no expansion was observed, ruling out the diagnosis of Friedreich's ataxia. In cases with GAA expansions, foot deformity, cardiac abnormalities, and some neurologic findings occurred more frequently; however, abnormalities in cranial nerves and in tomographic findings were detected less frequently than in patients without GAA expansions. DISCUSSION: Molecular analysis was imperative for the diagnosis of Friedreich's ataxia, not only for typical cases but also for atypical ones. There was no genotype-phenotype correlation. Diagnosis based only on clinical findings is limited; however, it aids in better screening for suspected cases that should be tested. Evaluation for vitamin E deficiency is recommended, especially in cases without GAA expansion.

    Full Text Available Objective: To evaluate five biomarkers (neopterin, vascular endothelial growth factor-A, thrombomodulin, soluble vascular cell adhesion molecule 1 and pentraxin 3 in differentiating clinical dengue cases. Methods: A prospective cohort study was conducted whereby the blood samples were obtained at day of presentation and the final diagnosis were obtained at the end of patients’ follow-up. All patients included in the study were 15 years old or older, not pregnant, not infected by dengue previously and did not have cancer, autoimmune or haematological disorder. Median test was performed to compare the biomarker levels. A subgroup Mann-Whitney U test was analysed between severe dengue and non-severe dengue cases. Monte Carlo method was used to estimate the 2-tailed probability (P value for independent variables with unequal number of patients. Results: All biomarkers except thrombomodulin has P value < 0.001 in differentiating among the healthy subjects, non-dengue fever, dengue without warning signs and dengue with warning signs/severe dengue. Subgroup analysis for all the biomarkers between severe dengue and non-severe dengue cases was not statistically significant except vascular endothelial growth factor-A (P < 0.05. Conclusions: Certain biomarkers were able to differentiate the clinical dengue cases. This could be potentially useful in classifying and determining the severity of dengue infected patients in the hospital.

    This paper reports a case study comparing the relative efficiency of using a Diabetes Registry or a Clinical Data Warehouse to recruit participants for a diabetes clinical trial, TECOS. The Clinical Data Warehouse generated higher positive predictive accuracy (31% vs. 6.6%) and higher participant recruitment than the Registry (30 vs. 14 participants) in a shorter time period (59 vs. 74 working days). We identify important factors that increase clinical trial recruitment efficiency and lower cost.

    Full Text Available Onychomycosis or fungal infection of the nails is a common disease, especially in older persons. A mycological study of onchomycosis was undertaken in 75 patients. The nails were judged to be infected by their clinical appearance. There were a total of 75 suspected cases of onychomycosis. Of these 75 cases 22.6% were positive by direct microscopy and 33.3% were culture positive. Of these 75 cases, 18 were males (24% and 57 (76 % were females, male to female ratio being. The commonest age group was 31-40 years followed by 21-30 years. The finger nails were more frequently involved. i.e. 45 (60 %, followed by toe nails 30 (40 % and both in 18 (24% cases. Ratio of finger nail to toe nail infection was 1.5:1. Distal and lateral subungual onychomycosis (DLSO was the commonest clinical pattern (76% followed by total dystrophic onychomycosis (18.66% and then superficial white onychomycosis (4% and proximal subungual onychomycosis (1.33%. The most common fungal isolates were dermatophytes of which 44% were Trytophyton rubrum, 4% were Trytophyton mentagrophytes. Non dermatophyte moulds constituted 16% of the fungus isolates. Onychomycosis was found to be the commonest in housewives (52%, followed by serviceman / businessman (32% followed by farmers (8% and labourer and student 4% each.

    Urticarial vasculitis (UV) is a subset of cutaneous vasculitis (CV), characterized clinically by urticarial skin lesions of more than 24 hours' duration and histologically by leukocytoclastic vasculitis. We assessed the frequency, clinical features, treatment, and outcome of a series of patients with UV. We conducted a retrospective study of patients with UV included in a large series of unselected patients with CV from a university hospital. Of 766 patients with CV, UV was diagnosed in 21 (2.7%; 9 male and 12 female patients; median age, 35 yr; range, 1-78 yr; interquartile range, 5-54 yr). Eight of the 21 cases were aged younger than 20 years old. Potential precipitating factors were upper respiratory tract infections and drugs (penicillin) (n = 4; in all cases in patients aged urticarial lesions, other features such as palpable purpura (n = 7), arthralgia and/or arthritis (n = 13), abdominal pain (n = 2), nephropathy (n = 2), and peripheral neuropathy (n = 1) were observed. Hypocomplementemia (low C4) with low C1q was disclosed in 2 patients. Other abnormal laboratory findings were leukocytosis (n = 7), increased erythrocyte sedimentation rate (n = 6), anemia (n = 4), and antinuclear antibody positivity (n = 2). Treatment included corticosteroids (n = 12), antihistaminic drugs (n = 6), chloroquine (n = 4), nonsteroidal antiinflammatory drugs (n = 3), colchicine (n = 2), and azathioprine (n = 1). After a median follow-up of 10 months (interquartile range, 2-38 mo) recurrences were observed in 4 patients. Apart from 1 patient who died because of an underlying malignancy, the outcome was good with full recovery in the remaining patients. In conclusion, our results indicate that UV is rare but not exceptional. In children UV is often preceded by an upper respiratory tract infection. Urticarial lesions and joint manifestations are the most frequent clinical manifestation. Low complement serum levels are observed in a minority of cases. The prognosis is generally good

    Introduction Dermatoses affecting palms and soles are among the most difficult of all dermatological therapeutic problems. Many previous studies have focused on the specific diseases of palmoplantar dermatoses. However, none of them have included a comprehensive study of palmoplantar dermatoses. Aims: To study the epidemiological aspects like age distribution, sex distribution, the dermatoses affecting the palms & soles and the frequency of involvement of palms, soles or both palms & soles, in patient with palmoplantar dermatoses. Materials and Methods This cross sectional study was conducted in the Department of Dermatology between October 2011 to September 2013. First 300 cases attending the department of dermatology primarily with complaints pertaining to palms and soles were enrolled in the study. After taking consent a detailed history and clinical examination pertaining to the aim of the study was recorded and analysed, which included inspection of morphology and distribution of lesions and palpation of any swelling. Direct microscopic examination of scrapings, wet mounted with 10% potassium hydroxide was done for cases with scaly lesions. Those who had a pustule, gram staining was done. Patch testing using Indian Standard Battery Series was done for those cases of eczema. A sample for biopsy was taken when diagnosis could not be arrived clinically, and subjected to histopathological examination. Results In our study of 300 patients with palmoplantar dermatoses, 164 were females and 136 were males, the ratio observed being 1.2:1. The peak incidence was found in the age group 21-30 years, with 41 females (25%) and 35 males (25.7%). Most frequently affected individuals in this study were housewives (30%). The most common five diseases of palmoplantar dermatoses were palmoplantar psoriasis (20.7%), moniliasis (19%), palmoplantar hyperhidrosis (7%), keratolysis exfoliativa (6%) and pitted keratolysis (6%). Majority of patients had involvement of both palms and

    Full Text Available From 1981 to 1992, 109 cases (90 females and 19 males of pemphigus were seen in the Department of Dermatology, Central Hospital Tripoli, Libya. Age of onset of the disease varied from 17 to 85 years, while duration of the disease at the time of presentation varied from 3 days to 13 days. On the basis of clinical features and routine histological findings the cases were divided into various subtypes as : pemphigus foliaceus 65 cases, pemphigus vulgaris 34 patients, pemphigus erythematosus 5, herpetiform pemphigus 3 and vegetans type 2 cases. Three of our patients had diabetes mellitus preceding pemphigus, while 12 patients developed steroid induced diabetes. Significant secondary bacterial infection occurred in all cases at some stage of the disease while oral candidiasis occurred in 15 cases. Eczema herpeticum was seen in 4 patients, while 2 had extensive tinea corporis. One of 4 patients of pemphigus vulgaris had complete shedding of nail and 1 female patient had alternate phases of pemphigus foliaceus and generalized pustular psoriasis. The features in our cases of pemphigus foliaceus were somewhat similar to Brazilian pemphigus foliaceus and we had more cases of pemphigus foliaceus, almost exclusively affecting females.

    Full Text Available This study explores the perception of satisfaction of caregivers who attended a feeding clinic at a large pediatric hospital in the midwest. The clinic is designed for a multidisciplinary team to meet with the child and the caregiver. Thirty-five participants were involved in the study. Results indicated that most participants were satisfied with the clinic experience. However, there were areas of care not covered by the members of the feeding team, which indicates a need. It is suggested that this need could be filled by occupational therapists.

    For many students in the health sciences, including doctor of pharmacy (PharmD) students, basic and clinical sciences often appear detached from each other. In the infectious disease field, PharmD students additionally struggle with mastering the diversity of microorganisms and the corresponding therapies. The objective of this study was to design an interdisciplinary project that integrates fundamental microbiology with clinical research and decision-making skills. The Emerging Microbe Project guided students through the identification of a microorganism via genetic sequence analysis. The unknown microbe provided the basis for a patient case that asked the student to design a therapeutic treatment strategy for an infected patient. Outside of lecture, students had two weeks to identify the pathogen using nucleotide sequences, compose a microbiology report on the pathogen, and recommend an appropriate therapeutic treatment plan for the corresponding clinical case. We hypothesized that the students would develop a better understanding of the interplay between basic microbiology and infectious disease clinical practice, and that they would gain confidence and skill in independently selecting appropriate antimicrobial therapies for a new disease state. The exercise was conducted with PharmD students in their second professional year of pharmacy school in a required infectious disease course. Here, we demonstrate that the Emerging Microbe Project significantly improved student learning through two assessment strategies (assignment grades and exam questions), and increased student confidence in clinical infectious disease practice. This exercise could be modified for other health sciences students or undergraduates depending upon the level of clinical focus required of the course.

    Full Text Available INTRODUCTION Benign Lesions of Larynx (BLL have been defined as “An abnormal mass of tissue in larynx, the growth of which exceeds and is coordinated with that of normal tissue and persists in the same excessive manner after cessation of stimuli which evoked the change.” These lesions have significant influence on vocal, social and emotional adjustments of patients. These patients present with hoarseness of voice. AIM A clinical study was undertaken at Govt. ENT Hospital, Hyderabad, for 1 year from January 2014 to December 2014. Aim of this study was to analyze age and sex distribution, symptomatology, sites of involvement, management and recurrence of benign lesions of larynx. MATERIAL AND METHODS A total of 50 patients were studied who were admitted in the hospital. Inclusion criteria: Patients with Hoarseness of Voice (HOV /change of voice, difficulty in breathing and swallowing, vocal fatigue, Foreign Body (FB sensation in the throat. Exclusion criteria: Malignancy of larynx and acute inflammatory conditions of larynx. RESULTS Benign lesions of larynx show male preponderance with M:F ratio of 2.12:1, with common age group between 31 to 40 years. Chronic vocal misuse was the predominant cause and more in professional voice users. The common lesion was Vocal Cord (VC polyp, followed by VC nodules and papillomas. Common side involved was right side. Majority of the patients had to undergo surgery. Majority of recurrence was seen in laryngeal papillomas (33.33%. CONCLUSION Benign lesions of larynx produce symptoms which vary from mild HOV to life threatening stridor. Early diagnosis leads to effective management. Males were more affected and maximum cases seen between 31 to 40 years. Chronic voice abuse, smoking, alcohol, frequent throat clearing and Laryngopharyngeal Reflux (LPR/Gastroesophageal Reflux Disease (GERD are precipitating factors. Microlaryngeal Surgery (MLS, voice rest and speech therapy offer a cost effective, useful and safe

    1985-06-01

    The clinical and radiographic findings in 104 patients with chondroblastoma are presented. Pain was an almost constant presenting complaint, often accompanied in the case of para-articular lesions by impaired function of an adjacent joint. The majority (80%) were in long bones with a mean age of presentation of 16 years. The characteristic radiological image of these lesions was an eccentric radiolucency, having a sharply defined sclerotic margin and containing areas of calcification in approximately a third of cases. They were always related to a growth plate. Nearly half were confined to the affected epiphysis or apophysis itself, but most of the remainder had traversed the growth plate to involve also the adjacent metaphysis. The bones around the knee and the proximal ends of the humerus and femur were the sites of predilection. A minority (20%) affected flat bones and short tubular bones of the hand and foot, with a peculiar affinity for the calcaneus and talus. The mean age of presentation of these was 28 years. The radiological pattern was similar, except for a greater tendency to expand the affected bone. Complications included the formation of a secondary aneurysmal bone cyst in 16 cases (10 of them in long bones), one malignant chondroblastoma, and one fibrosarcoma developing after radiation of the original chondroblastoma.

  19. A clinical study of 152 cases of glottic cancer

    International Nuclear Information System (INIS)

    One hundred fifty-two cases of glottic squamous cell carcinoma primarily treated in our hospital as inpatients during 22 years between 1989 and 2011 were retrospectively studied. They had been comprehensively treated with X-rays radiation in all cases (median dose 66 Gy), with chemotherapy in 69 cases (fluorouracil + carboplatin administered as induction chemotherapy (ICT) or concurrent chemoradiotherapy (CCRT)), followed by total laryngectomy if unavoidable. Their median age was 67.0 years ranging from 38 to 89, and the male to female ratio was 37:1 and median observation time was 71.5 months. According to the 6th edition of the Union for International Cancer Control (UICC) classification, there were 75 cases with Stage I, 43 cases with Stage II, 25 cases with Stage III, and 9 cases with Stage IV. For all cases, the 5-year cause-specific survival rate and 5-year overall survival rate were 91.7% (95% CI, 85.0-98.4) and 82.3% (95% CI, 73.5-91.1). In each stage, both rates were 95.2/88.4% with Stage I, 100/83.6% with Stage II, 86.7/75.9% with Stage III, and 44.4/44.4% with Stage IV, which were identified as statistically significant (p<0.0001). Three types of histopathological differentiation in squamous cell carcinoma were not found to contribute to the statistically significant difference in the prognosis of glottic cancers. Laryngeal preservation rate at 5 years in all cases was 73.2% (95% CI, 65.3-81.1). Regarding T-stages, the rates were 84.4% with T1, 81.6% with T2, 32.1% with T3 and 0% with T4 (p<0.0001). Furthermore, we clarified that there was no statistically significant difference between 5-year CSS rates in the two groups of laryngectomy cases and non-laryngectomy cases in the stages of T3 and T4 (p=0.6948). Our data were dissolved to be statistically not recessive in comparison with other data retrieved from six institutes, and showed the possibility of preservation of the larynx in T3 cases if sufficiently comprehensive treatment such as CCRT is carried

    Full Text Available Acute normovolaemic haemodilution (ANH is a technique used to preserve a patient's owns red blood cells and reduce the incidence of heterogeneous blood transfusion. This paper describes the use of the technique in a dog and a kitten. A significant benefit of ANH can be shown in the canine case presented. The dog lost 1800m of blood during surgery but the haematocrit was only reduced to 33% 6 hours after the end of surgery. The kitten, however, did not benefit from ANH. It lost a small volume of blood during surgery and developed complications. This paper also describes some of the potential complications that may occur. To the best of my knowledge, this is the 1st clinical description of ANH in a dog and a cat.

  1. Endocrine tumor of the digestive tract - clinical case study

    International Nuclear Information System (INIS)

    Introduction: Endocrine tumors of the digestive tract (ETDT) are neoplasms which stem from the APUD (amine precursors uptake and decarboxylation) cells. There are neuroendocrine pancreatic and gastroenteral carcinoid tumors which stand for 2% of digestive tract tumors, 0,5% of all human malignant neoplasms. All of them have secretion granulations in the cytoplasm. That is why a number of immune histochemic techniques is used in search for biogenic amines and hormones such as gastrin, CCK, GIP, VIP, motilin, glucagon, GRP, PP, GHRH and the others. In the majority of cases neuroendocrine tumors of the rectum are described as dysfunctional, which means that specific clinical symptoms are not connected with their hormonal overproduction. Material and methods: We describe a case of fifty seven years old male patient admitted to the Department of General and Transplant Surgery for the diagnosis and treatment of the rectal tumor. Per rectum examination revealed hard tumor. The pathologic examination of the biopsy taken from the lesion and CT scanning confirmed the presence of endocrine tumor of the digestive tract. Results: Anterior resection of the rectum was performed, the postoperative course was uneventful. At present patient is subjected to complementary treatment with the use of somatostatin analogue of the prolonged action. Conclusion: The endocrine tumors of the rectum are extremely rare, they occur in this localization in 0,26-0,52 out of 100.000 all rectal tumors. Diagnosis is usually made upon the microscopic examination and the immune histochemic reactions. (author)

  2. The Clinical Study on 39 Cases of Subclinical Hypothyroidism

    International Nuclear Information System (INIS)

    Subclinical hypothyroidism can be defined as an asymptomatic state in which a reduction in thyroid activity has been compensated by an increased TSH output to maintain an euthyroid state. We analysed clinical features, laboratory data, and pathologic findings in 39 cases of subclinical hypothyroidism who were diagnosed at the Dept. of Internal Medicine, Chungnam National University Hospital from Aug. 1984 to June, 1985. 1) The age distribution was from sixteen to sixty-nine and mean age was 34.8. Peak incidence was in the 4th decade and 3rd, 5th, 6th decade in order. 2) The sex distribution showed female preponderance with a ratio of 18.5 to 1. 3) The major presenting manifestations were nonspecific ones such as fatigue, indigestion, and anorexia. 4) Physical examination revealed diffuse goiter in 47.6%. Major abnormalities were no gross abnormality (30.9%), nodular goiter and facial edema. 5) There was no significant difference of the basal serum T3 and T4 concentrations between subclinical hypothyroidism and normal controls (p>0.05). 6) The basal serum TSH concentration of subclinical hypothyroidism (32.61±14.95 μU/ml) was significantly higher than that of normal controls (3.92±1.05 μU/ml) (p<0.005). 7) Microsomal antibody was detected in 80.6% and thyroglobulin antibody was detected in 30%. 8) The pathologic findings in 26 cases revealed Hashimoto's thyroiditis in 76.9% (lymphocytic type, 34.6%; oxyphilic type, 26.9%; fibrotic type, 15.4%). The others were adenomatous goiter (15.4%), adenomatous carcinoma (3.8%) and subacute thyroiditis (3.8%).

    Hemangiosarcoma (HSA) is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be comm...

    Full Text Available BACKGROUND : Forefoot eczema (FE is characterized by dry fissured dermatitis of the plantar surface of the feet. AIM : To study the clinical profile of FE and the possible etiological factors. METHODS : Forty-two patients with FE were included in the study. A detailed history was recorded and examination done. Fungal scrapings and patch test with Indian Standard Series (ISS were performed in all patients. RESULTS : The most common site affected was the plantar surface of the great toe in 16 (38.09% patients. Hand involvement, with fissuring and soreness of the fingertips and palm, was seen in four patients (9.5%. Seven patients (16.6% had a personal history of atopy whereas family history of atopy was present in six (14.2%. Seven patients (16.6% reported aggravation of itching with plastic, rubber or leather footwear, and 13 (30.9%, with detergents and prolonged contact with water. Negative fungal scrapings in all patients ruled out a dermatophyte infection. Patch testing with ISS was performed in 19 patients and was positive in five. CONCLUSIONS : FE is a distinctive dermatosis of the second and third decade, predominantly in females, with a multifactorial etiology, possible factors being chronic irritation, atopy, footwear and seasonal influence.

    We describe an innovative program at the University of California, Davis for students to engage in clinical needs finding. Using a team-based approach, students participated in clinical rotations to observe firsthand the needs of clinicians at the university affiliated medical center. The teams were asked to develop documentary-style videos to capture key experiences that would allow future viewers to use the videos as “virtual” clinical rotations. This was conceived as a strategy to allow students in prohibitively large classes, or students in programs at institutions without associated medical or veterinary school programs, to experience clinical rotations and perform needs assessments. The students' perspectives on the experience as well as instructor analysis of best practices for this type of activity are presented and discussed. We found that the internship experience was valuable to the students participating, by not only introducing the practice of needs finding but for increasing the students' confidence in the practice of engineering design and their ability to work independently. The videos produced were of such high quality that instructors from other institutions have requested copies for instructional use. Virtual clinical rotations through video experiences may provide a reasonable substitute for students who do not have the ability to participate in rotations in person. PMID:23483373

    The objective of this paper is to provide considerations based on comprehensive case studies important for regulatory evaluation of monoclonal antibodies as similar biotherapeutic products (SBPs) with a special emphasis on clinical aspects. Scientific principles from WHO Guidelines on SBPs were used as a basis for the exercise. Working groups consisted of regulators, manufacturers and academia. The following topics were discussed by the working groups: clinical criteria for biosimilarity, extrapolation approach and the overall regulatory decision making process. In order to determine typical pitfalls in the design of a SBP clinical programme and evaluate the gap of knowledge, amongst different industry and regulatory stakeholders on the appraisal of the data arising from SBP clinical studies, we have presented two fictional but realistic clinical case studies. The first case consists of the fictional development programme for an infliximab SBP candidate. The second case describes clinical studies proposed for a fictional rituximab SBP candidate. In the first scenario a highly similar quality profile has been taken forward into clinical studies whereas there was an important residual difference in functional attributes for the rituximab SBP candidate. These case studies were presented at the WHO implementation workshop for the WHO guidelines on evaluation of similar biotherapeutic products held in Seoul, Republic of Korea, in May 2014. The goal was to illustrate the interpretation of the clinical data arising from studies with SBP candidates and elicit knowledge gaps in clinical assessment. This paper reflects the outcome of the exercise and discussions held in Seoul and offers an analysis of the case studies as a learning opportunity on clinical development and evaluation of SBPs.

    Full Text Available Hemangiosarcoma (HSA is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be communicated to those responsible for the pets, so that, with all available information, they can make a free and informed choice about the treatment they want for their pet, considering the financial commitment, survival time and quality of life associated with chemotherapy. This article describes the clinical case of a female greyhound dog of eight years of age that was brought to consultation for a skin tumor on the right hind limb in the distal tibia. She was diagnosed with noninvasive cutaneous HSA through histopathology, reason why the owners chose not to do the chemotherapy; however, 10 months later she presented recurrent skin lesions and a popliteal lymph node corresponding to hemangiosarcoma and hemangioma respectively, and three weeks later the patient developed cardiac tamponade due to a cardiac mass with associated spill, which resulted in her euthanasia.

    Hypnotherapy's effectiveness in improving and controlling chronic pain of various etiologies has been demonstrated by studies; the mechanism by which hypnosis does this is more complex than a simple induction of muscle relaxation. This study reveals, in addition to this mechanism, a deeper dimension of hypnotherapy from the vantage of a patient with a medical-surgical background, diagnosed with a pain disorder and major severe depressive disorder in addition to incurable painful symptoms, through treatment associated with hypnoanalysis. Following psychotherapy, which included some elements of cognitive-behavioral therapy, a complete remission of the anxious-depressive mood and the painful symptoms was achieved. PMID:25719524

    Full Text Available BACKGROUND: Oral cancer is of significant public health importance to India. Oral cancer will remain a major health problem and efforts towards early detection , and prevention will reduce this burden. A premalignant lesion is a disease , syndrome , or finding that , if left untreated , may lead to cancer. OBJECTIVE: To understand the prevalence , clinical and morphological profile of oral premalignant lesions. MATERIALS AND METHODS : Clinical material for present study comp rises 75 cases with oral premalignant lesions. The parame ters studied were types of oral premalignant lesions , age distribution , sex distribution , the local habits of addiction and the sites of involvement. RESULTS : Maximum number of cases was between 21 - 3 0 years of age. The sex incidence was more in males with the ratio of 9:1. Out of total 75 cases , 64% cases were of oral submucous fibrosis , 17.3% cases were of leukoplakia , 8% cases of erythroplakia , 6.6% cases of traumatic dental ulcer and 4% cases of li chen planus. In cases of oral submucous fibrosis , betel nut chewing was the commonest habit (89.5%. In cases of Lichen planus no addictions were found. Buccal mucosa was the commonest site involved in premalignant lesions. CONCLUSION: Premalignant lesions are seen mainly in early adulthood. The number of cases is increased due to adverse oral habits. Its prevalence can be reduced if awareness is created among such patients. This study mandates close cooperation between dentist and ENT surgeons.

    openEHR is a flexible and scalable modeling methodology for clinical information and has been widely adopted in Europe and Australia. Due to the reasons of differences in clinical process and management, there are few research projects involving openEHR in China. To investigate the feasibility of openEHR methodology for clinical information modelling in China, this paper carries out a case study to apply openEHR archetypes to Clinical Data Repository (CDR) in a Chinese hospital. The results show that a set of 26 archetypes are found to cover all the concepts used in the CDR. Of all these, 9 (34.6%) are reused without change, 10 are modified and/or extended, and 7 are newly defined. The reasons for modification, extension and newly definition have been discussed, including granularity of archetype, metadata-level versus data-level modelling, and the representation of relationships between archetypes.

    The Health and Social Care Act 2012 heralded wide reaching reforms intended to place clinicians at the heart of the health service. For NHS general dental practice, the conduits for this clinical leadership are the NHS England local professional networks. In Greater Manchester, the local professional network has developed and piloted a clinician led quality improvement project: 'Healthy Gums DO Matter, a Practitioner's Toolkit'. Used as a case study, the project highlighted the following facilitators to clinical leadership in dentistry: supportive environment; mentoring and transformational leadership; alignment of project goals with national policy; funding allowance; cross-boundary collaboration; determination; altruism; and support from wider academic and specialist colleagues. Barriers to clinical leadership identified were: the hierarchical nature of healthcare, territorialism and competing clinical commitments. PMID:26404983

    Full Text Available Context: Leptospirosis is a zoonotic infection with worldwide significance. It is caused by a spirochete Leptospira interrogans, which has many serogroups and a large number of serovars. Leptospirosis is an emerging public health problem in India. Aims: Leptospirosis is an emerging public health problem and keeping this in mind 216 clinically suspected cases of leptospirosis have been considered for serological study. Failure to recognize these cases leads to serious morbidity and mortality. Hence, the present study was undertaken to identify these cases by simple laboratory techniques so that timely management could be undertaken. Settings and Design: Hospital-based cross-sectional case control study. Subjects and Methods: Patients with unexplained fever for more than seven days with or without jaundice or renal failure were taken up for this study. IgM ELISA tests were performed with the serum samples of the patients. Statistical Analysis Used: Simple statistical methods applying Epi info. Results: Total 77 patients were found to be reactive for IgM ELISA. Total 100% of seropositive patients had fever and 40% had jaundice. Peak incidence of the disease was found in the period from July to November (monsoon and post-monsoon period. Male preponderance was seen and mainly urban population was found to be seropositive in our study. Conclusions: Seroprevalence of leptospirosis was found to be remarkable in our study; 35% of the clinically suspected patients showed positive IgM ELISA tests.

    Genetic case-control association studies often include data on clinical covariates, such as body mass index (BMI), smoking status, or age, that may modify the underlying genetic risk of case or control samples. For example, in type 2 diabetes, odds ratios for established variants estimated from low–BMI cases are larger than those estimated from high–BMI cases. An unanswered question is how to use this information to maximize statistical power in case-control studies that ascertain individuals on the basis of phenotype (case-control ascertainment) or phenotype and clinical covariates (case-control-covariate ascertainment). While current approaches improve power in studies with random ascertainment, they often lose power under case-control ascertainment and fail to capture available power increases under case-control-covariate ascertainment. We show that an informed conditioning approach, based on the liability threshold model with parameters informed by external epidemiological information, fully accounts for disease prevalence and non-random ascertainment of phenotype as well as covariates and provides a substantial increase in power while maintaining a properly controlled false-positive rate. Our method outperforms standard case-control association tests with or without covariates, tests of gene x covariate interaction, and previously proposed tests for dealing with covariates in ascertained data, with especially large improvements in the case of case-control-covariate ascertainment. We investigate empirical case-control studies of type 2 diabetes, prostate cancer, lung cancer, breast cancer, rheumatoid arthritis, age-related macular degeneration, and end-stage kidney disease over a total of 89,726 samples.

    Translational medicine is becoming increasingly dependent upon data generated from health care, clinical research, and molecular investigations. This increasing rate of production and diversity in data has brought about several challenges, including the need to integrate fragmented databases, enable secondary use of patient clinical data from health care in clinical research, and to create information systems that clinicians and biomedical researchers can readily use. Our case study effectively integrates requirements from the clinical and biomedical researcher perspectives in a translational medicine setting. Our three principal achievements are (a) a design of a user-friendly web-based system for management and integration of clinical and molecular databases, while adhering to proper de-identification and security measures; (b) providing a real-world test of the system functionalities using clinical cohorts; and (c) system integration with a clinical decision support system to demonstrate system interoperability. We engaged two active clinical cohorts, 747 psoriasis patients and 2001 rheumatoid arthritis patients, to demonstrate efficient query possibilities across the data sources, enable cohort stratification, extract variation in antibody patterns, study biomarker predictors of treatment response in RA patients, and to explore metabolic profiles of psoriasis patients. Finally, we demonstrated system interoperability by enabling integration with an established clinical decision support system in health care. To assure the usefulness and usability of the system, we followed two approaches. First, we created a graphical user interface supporting all user interactions. Secondly we carried out a system performance evaluation study where we measured the average response time in seconds for active users, http errors, and kilobits per second received and sent. The maximum response time was found to be 0.12 seconds; no server or client errors of any kind were detected

    Pyotraumatic dermatitis (hot spot) is a common clinical syndrome in dogs but there are few prospective scientific studies related to it. The aim of this study was to investigate correlations among clinical pyotraumatic dermatitis, histopathology of the lesions and possible predisposing causes. The relationship of these with breed, age, sex and location of lesion was assessed statistically. A clinical diagnosis of acute pyotraumatic dermatitis was made in 44 privately owned dogs. Males exceeded females (P = 0.0348) and lesions were more common in dogs aged 4 years or less (P otitis externa was recorded and the study was conducted in an area without endemic fleas. Fourteen breeds were represented of which Rottweiler, German shepherd dog and golden retriever were most common. There was no significant seasonal incidence and no correlation among site of lesion and cause, time of year, age or sex. Histopathologically, the dogs could be separated into four patterns by the presence or absence of eosinophils and/or folliculitis. Eosinophils have not previously been recorded in pyotraumatic dermatitis but were seen in 29 cases. Acute folliculitis was seen in 20 cases. However, no correlation was seen among age, sex, breed, underlying cause or site of lesion and histopathology. Twenty-seven cases were cultured for bacteria of which 25 grew Staphylococcus intermedius and two were negative.

    Polydactyly is one of the most common hereditary limb malformations, involving additional digits on the hands and/or feet, which is a very attractive model to appreciate clinical and genetic heterogeneity. A high level of heterogeneity in polydactyly has been identified in different regions. However, such data of the medical literatures for Asian populations are relatively limited. This study was intended to shed light on the phenotypic manifestations of polydactyly in the recruited Chinese population and to characterize the medical literature on this condition. A total of 459 well-characterized polydactyly cases from Shanghai Children's Medical Center were recruited. Their phenotypes, inheritance patterns, and clinical heterogeneity were obtained from clinical medical records. It was found that 4.8% of cases were familial and 95.2% were sporadic. The proportions of preaxial and postaxial polydactyly types were 74.7% and 25.3%, respectively. In preaxial polydactyly, type I formed the overwhelming majority (95.9%). Among the postaxial polydactyly cases, type A was most prevalent at 69.8% and type B was witnessed in 30.2% of cases. Familial and sporadic polydactyly patients mainly had unilateral presentations. A total of 583 limbs with additional digits were recorded in the 459 subjects. Upper limb involvement was more common than lower, and right hand involvement was more common than left for preaxial polydactyly, and lower limb involvement was more common than upper in postaxial polydactyly. This cohort added useful clinical/epidemiological information to the polydactyly literature in the Chinese population and highlighted its marked clinical heterogeneity.

    In the final part, a clinical reflection is presented on the dark side of identity formation and the empirical papers of this special issue. It is important that both researchers and clinicians ask themselves how theory and evidence about identity development can be used in clinical practice. Therefore, a relevant case study is presented about an emerging adult struggling with identity formation, Tim. Various facets of Tim's struggling are illustrated based on findings from this special issue. Starting from identity diffusion, Tim's transition to moratorium and achievement was examined from three complementary theoretical frameworks and related research on these topics as outlined in this special issue. Finally, change processes throughout therapy were discussed from various clinical frameworks.

    Tabes dorsalis (TD) was documented as the most common parenchymal neurosyphilis, but its incidence dramatically declined in the antibiotic era. Syphilis has resurged on the China mainland since the 1980s. In recent years, physicians have been reporting parenchymal neurosyphilis, and the overwhelming majority was general paresis, but this was not the case in the authors' hospital. To make clear the real situation of parenchymal neurosyphilis in the authors' hospital, a retrospective review was carried out of the records of patients during 2009-2012. Overrepresented clinical new cases of tabetic and paretic parenchymal neurosyphilis were collected. Clinical characteristics, neuroimaging, laboratory data, and responses to penicillin were analyzed in two groups. The efficiency of two current criteria based on CSF antibodies tests was inspected. In the 43 cases with positive serum rapid plasma reagin (RPR) and TPPA tests, 18 patients met the criteria of this study: 11 presented with symptoms of general paresis, and seven had typical presentations of TD. There were statistical differences in serum RPR titers, CSF RPR, white blood cell count, and TP between the paretic and tabetic groups. The response to penicillin was relatively poor in TD. The efficiency of two current criteria was lower in the diagnosis of TD. TD was not uncommon in our area. Its clinical features remained typical, but underdiagnosis with CSF-based criteria and a decreased response to penicillin were prominent issues. PMID:25321411

The aim of the present study is to describe the characteristic clinical features of adolescents with DSH according to our local context (Lisbon, Portugal, using easily available information from clinical settings. A case control study was constructed from a sample of 100 adolescents (aged 12 to 21 years. The sample was divided into two groups: adolescents with and without DSH. Case files were examined and data was completed by clinical interviews. Demographic, psychosocial, and psychopathological data were assessed and compared. Ninety-eight subjects completed the protocol. The DSH group was associated with the following: suicidal ideation or suicidal behavior as consultation motive, emergency room referral, previous follow-up attempts, suicidal ideation, psychosocial difficulties, or lack of therapeutic goals. There was a nonsignificant trend towards diagnosis of depression in the DSH group. These results reflect our clinical practice with adolescents and add data about teenagers who self-harm to the literature. Prevention and early recognition of DSH (and frequently associated depression in adolescents are essential and could be life-saving measures. An integrated approach, which takes into account psychosocial difficulties, family dysfunction, and negative expectations, seems to be of great importance.Keywords: deliberate self-harm, suicide, adolescents, suicide risk, case control

    Acute spinal cord infarction (ASCI) occurs infrequently and may have diverse causes. The diagnosis of ASCI, and particularly of an anterior spinal artery syndrome (ASAS) can be confirmed nowadays by MRI, whereas in the past only necropsy confirmation was possible. Pathophysiology and long-term prognosis may be better known at present and treatments more consistent. We present the longitudinal study and clinical features of 8 patients suffering from ASCI. All of them were personally studied and had MRI examinations, often with sequential studies. three groups must be considered: one included 4 cases of ASAS at cervical level, the second 2 cases of ASAS at thoracic level and the third group with infarction of the conus medullaris (ICM), one of them developed during surgical repair of an infrarenal aortic aneurysm. Motor and sensory sequelae were assessed in each case together with possible etiological factors. In conclusion, recovery after ASAS tends to be dependent on the severity of the initial deficit. At cervical level, clinical and morphological findings argue in favour of an extrinsic selective compression of the C7 right radiculo-medullary artery as responsible for the ASA. At thoracic level, the artery preferentially occluded seems to be the sulco-commisural artery as a consequence of disc compression. Finally, an underlying peculiarity of the pattern of arterial supply is a probable predisposing factor for ICM. Generally, the long-term prognosis of ASCI is not necessarily bad. PMID:7801036

    Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, pcase rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

    Full Text Available BACKGROUND: Lichen amyloidosus (LA is a primary localized cutaneous amyloidosis characterized clinically by discrete hyperkeratotic hyperpigmented papules and histologically by deposition of amyloid material in previously normal skin without any evidence of visceral involvement. AIMS AND OBJECTIVES: The aim of this work was to study the etiology, clinical features, histopathology and direct immunofluorescence findings in LA. METHODS: A prospective study of 30 patients with clinical, histological and immunofluorescence findings suggestive of LA was undertaken. After a detailed history and clinical examination, two punch biopsies for histopathology and immunofluorescence were taken. RESULTS: Of the 30 patients, 19 (63.3% were males and 11 (36.7% were females with duration of LA ranging from 6-20 months. Pruritus was the presenting symptom in 27 (90% patients. Shin was involved in 26 (86.7% followed by arms in three (10% and back in one (3.3%. Seventeen patients (56% had used scrubs for more than 2 years. Histopathology, direct immunofluorescence and Congo red staining detected amyloid in all cases. CONCLUSIONS: LA commonly presents over the shins as pruritic discrete hyperpigmented papules. Familial predisposition and friction may have a pathogenic role. Histopathological examination is very useful in the detection of amyloid which may be supplemented with direct immunofluorescence and Congo red staining.

    2013-07-01

    Full Text Available Clinical, pathoanatomical, histological, and bacteriological studies were performed on broiler chickens, growing broiler parents, and growing egg layers, in three different poultry farms, after an outbreak of Pseudomonas aeruginosa infections. The method of contamination of the birds was established. Several local and systemic clinico-morphological forms of spontaneous P. aeruginosa infections in various categories of stock birds were described: cases of P. aeruginosa infection resulting from injection of contaminated vaccines; case of P. aeruginosa infections through contaminated aerosol vaccine and cases of pododermatitis, periarthritis and arthritis in broiler chickens associated with P. aeruginosa infection. In different cases mortality range between 0.5 and 50%. The results showed that apart from embryonic mortality in hatcheries, and septicemic infections in newly hatched chickens, the pathogenicity of P. aeruginosa was associated with localized and systemic lesions in this category, as well as in young and growing birds. On one hand, these results have a theoretical significance, contributing for the confirmation and expansion of the wide array of clinico-morphological forms of P. aeruginosa infections in birds. On the other hand, the knowledge on these forms has a purely practical significance in the diagnostics of P. aeruginosa infections by poultry pathologists and veterinary practitioners.

    A clinical AIDS case definition is needed for surveillance in countries where the CDC case definition is not practical. To derive such a definition, we compared 110 HIV-seropositive and 135 randomly selected HIV-seronegative adult medical-ward inpatients in Brazil. Multivariate analysis of clinical signs and symptoms and simple diagnoses resulted in a discriminant function with sensitivity of 89% and specificity of 96% in predicting for AIDS. These data were the empirical basis for a clinical definition of AIDS in adults drafted in a Caracas, Venezuela, workshop sponsored by the Pan American Health Organization. The revised "Caracas" definition presented here requires a positive HIV serology, the absence of cancer or other cause of immunosuppression, plus > or = 10 cumulative points, as follows: Kaposi's sarcoma (10 points); extrapulmonary/noncavitary pulmonary tuberculosis (10); oral candidiasis or hairy leukoplakia (5); cavitary pulmonary/unspecified tuberculosis (5); herpes zoster or = 1 month (2); fever > or = 1 month (2); cachexia or > 10% weight loss (2); asthenia > or = 1 month (2); persistent dermatitis (2); anemia, lymphopenia, or thrombocytopenia (2); persistent cough or any pneumonia except TB (2); and lymphadenopathy > or = 1 cm at > or = 2 noninguinal sites for > or = 1 month (2). This definition has a sensitivity of 95% and a specificity of 100% (91% without HIV serology) when applied to the Brazilian patients in this study. The Caracas definition has been adopted by Brazil, Honduras, and Surinam, and is in validation elsewhere. The use of a reasonably sensitive and specific case definition commensurate with available diagnostic resources should facilitate AIDS surveillance in developing countries. PMID:1453332

    Full Text Available Objective To summarize the clinical data and pathological features of 10 cases of cerebral lobar hemorrhage related with cerebral amyloid angiopathy (CAA diagnosed pathologically, thereby to improve the knowledge and diagnosis of the disease. Methods The clinical data of 10 cases of cerebral lobar hemorrhage related with CAA, collected in the General Hospital of Shenyang Command from 1983 up to now, were retrospectively analyzed, and the clinical and neuropathological features of these cases were summarized. Results Of the 10 patients, 2 suffered from single lobar hemorrhage and 8 multiple lobar hemorrhage, all of them were confirmed pathologically to have ruptured into the subarachnoid space. Pathological examination revealed microaneurysm in 2 cases, "double barrel" change in 4 cases, multiple arteriolar clusters in 5 cases, obliterative onion-liked intima change in 4 cases, and fibrinoid necrosis of vessel wall in 7 cases. In addition, neurofibrillary tangles were found in 8 cases, and senile plaque was observed in 5 cases. Conclusions Cerebral lobar hemorrhage related with CAA is mainly located in the parietal, temporal and occipital lobes, readily breaking into the subarachnoid space, and it is often multiple and recurrent. The CAA associated microvasculopathy was found frequently in the autopsy sample of CAA related cerebral lobar hemorrhage, and it may contribute to the pathogenesis of cerebral hemorrhage.

    Full Text Available Background and Design: In this study, we aimed to evaluate the efficacy, safety and side effects of infliximab therapy in patients followed up in our clinic with moderate-severe psoriatic patients unresponsive to conventional therapies.Material and Method: Twenty-six psoriasis patients who were given infliximab therapy in our clinic between years 2006-2008, were retrospectively analyzed for their demographical clinical features, changes in PASI score, duration, efficacy and adverse effects of the therapy. Results: There were 15 female and 11 male psoriasis patients; ages ranging from 18 to 70 years (45.2±12.9. 17 of them were diagnosed as generalize plaque type psoriasis, 2 as eritrodermic psoriasis, 5 as generalize pustular, two of them as palmoplantar pustular psoriasis. Thirteen have associated psoriatic arthritis. All patients received 5 mg/kg intravenous infliximab infusion at weeks 0, 2, and 6, followed by every 8 weeks. Number of infliximab therapy sections was ranging from 2 to 16 and duration of treatment from 1 month to 28 months. Improvement in PASI between pretreatment and after induction therapy was statistically significant (p<0.05. Additional systemic treatment for disease activation was applied to patients receiving infliximab monotherapy at 14.-38. weeks. We observed allergic infusion reactions in 15.4% of the patients. Conclusion: In compatible with data in literature, we found that infliximab therapy provides a rapid clinical response in patients (generalized, eritrodermic and/or pustular psoriasis who are unresponsive to immunosupressive agents or in cases which these treatment modalities cannot be used because of side effects.

    Drug-induced liver injury may cause impairment of liver function and is a leading cause of acute liver failure. Identification of the causative substance in patients receiving several drugs is often difficult in clinical practice. Evaluation of liver biopsies in suspected drug-induced injury is a challenging task that requires close clinico-pathological correlation. Recognizing a characteristic morphological pattern of liver injury may contribute to identification of the causative drug. Flupirtine, a non-opioid analgesic, has been reported to cause liver injury of idiosyncratic type in rare instances. We wished to characterize the histopathological features of flupirtine-induced liver injury, which have not been reported so far. Liver biopsies of five patients with severe liver injury and one explanted liver of a patient with flupirtine-induced acute liver failure that required transplantation were assessed. In addition clinical presentation and course were reviewed and clinical follow up was performed. Extensive perivenular necrosis with associated ceroid pigment-laden macrophages and a mild to moderate lymphocytic infiltrate was a common feature in all cases. Histological extent of liver necrosis corresponded well to serum amino-transferase levels. Accidental reexposure of one patient resulted in a plasma cell rich hepatitis with perivenular necrosis. This study provides evidence that flupirtine can cause substantial liver injury of hepatocellular type. Liver damage is associated with a characteristic morphological picture, the recognition of which will aid in causality assessment of drug-induced liver injury. Clinical and histological features raise the possibility of an immune-mediated toxicity. PMID:21590308

    Use of terminology standards facilitates aggregating data from multiple sources for information retrieval, exchange and analysis. However, medical vocabularies are continuously updated and incorporating those changes consistently into clinical data warehouses requires rigorous methodology. To integrate pharmacy data from two hospital pharmacy information systems the Stanford Translational Research Integrated Database Environment (STRIDE) project mapped medication orders to RxNorm content using the RxNorm drug model. In order to keep the data relevant and up-to-date, we developed a strategy for updating to RxNorm, while preserving the original meaning and mapping of the legacy data. This case study discusses managing the vocabulary update by following the RxNorm content maintenance strategy and supplementing it with operations to retain access to its drug model information.

    Less than 10 cases of bites by Philodryas olfersii (Colubridae) have been reported in the literature. In this study, 43 patients admitted to the Instituto Butantan, São Paulo, Brazil, with the diagnosis of P. olfersii bite from 1982 to 1990 were reviewed. The 32 male (74.4%) and 11 female (25.6%) patients presented mainly from November to February (65%). The most common clinical features were local pain (37.2%), swelling (34.9%), erythema (18.6%) and ecchymosis (9.3%). The 20 minute whole blood clotting test was performed in 11 patients and in all of them the blood was coagulable. Most of the accidents occurred during the hottest months and during daylight hours. The most common bite site was the hands. Severe envenoming is not frequent in these accidents. PMID:10340833

    Teaching caring in nursing is expected of nursing faculty, but the practical application is rarely explained. It has been regarded as the moral responsibility of faculty to teach in a caring way. This case study relates how one faculty applied the concepts to quadrangular dialogue a caring model of nursing education to the experience of baccalaureate student nurses in their first clinical rotation. The components of quadrangular dialogue will be described, and applied to a specific patient who was cared for by students in one semester. This model is developed from Habermas' (1995) Theory of Communicative Action and Moral Consciousness, Bishop and Scudder's (1990) Triadic Dialogue and a caring in nursing paradigm developed by this author. It explains how the patient, nursing student and nursing faculty are all first person in the interaction, while the illness is object. By acknowledging the humanness of participants, validation and fulfillment for each follow. PMID:16646898

    Full Text Available Abstract Background New antimalarial regimens, including artemisinin-based combination therapies (ACTs, have been adopted widely as first-line treatment for uncomplicated malaria. Although these drugs appear to be safe and well-tolerated, experience with their use in Africa is limited and continued assessment of safety is a priority. However, no standardized guidelines for evaluating drug safety and tolerability in malaria studies exist. A system for monitoring adverse events in antimalarial trials conducted in Uganda was developed. Here the reporting system is described, and difficulties faced in analysing and interpreting the safety results are illustrated, using data from the trials. Case description Between 2002 and 2007, eleven randomized, controlled clinical trials were conducted to compare the efficacy, safety, and tolerability of different antimalarial regimens for treatment of uncomplicated malaria in Uganda. The approach to adverse event monitoring was similar in all studies. A total of 5,614 treatments were evaluated in 4,876 patients. Differences in baseline characteristics and patterns of adverse event reporting were noted between the sites, which limited the ability to pool and analyse data. Clinical failure following antimalarial treatment confounded associations between treatment and adverse events that were also common symptoms of malaria, particularly in areas of lower transmission intensity. Discussion and evaluation Despite prospectively evaluating for adverse events, limitations in the monitoring system were identified. New standardized guidelines for monitoring safety and tolerability in antimalarial trials are needed, which should address how to detect events of greatest importance, including serious events, those with a causal relationship to the treatment, those which impact on adherence, and events not previously reported. Conclusion Although the World Health Organization has supported the development of

    The antecubital flap is a fasciocutaneous strip that has its blood supply provided by the first proximal collateral of the radial artery. This flap was described for the first time in 1983 by Lamberty and Cormack, but it has not been widely used and there have been only a few reports in the literature concerning this procedure. The aim of the present investigation was to demonstrate via an anatomical study and a report on five cases the viability of the various anatomical features of this cutaneous flap, and also its positive contribution to elbow reconstruction. The anatomical study involved eight fresh cadavers (eight upper limbs). An injection of colored prevulcanized latex was made in the humeral artery in the lower third of the arm. The aim was to determine which artery provided blood supply to the flap, its anatomical location, and also to look for possible distal anastomoses which would permit a distal pedicled flap to be removed. Contrary to the findings of other authors, in the present study it was found that the vessel providing blood to the antecubital flap always branched off from the radial artery. However, no anastomoses with distal vascularization were detected, which would have permitted a distal pedicled flap to be obtained. The use of the antecubital flap for elbow coverage was then illustrated by five clinical cases of soft tissue defects of the elbow. This method was found to be reliable, practical, and the flap could be rapidly dissected. Moreover, this particular technique is sensitive, and has an interesting rotational arc. The distal cutaneous island flap has the advantage of limiting scar tissue. A comparison between the antecubital flap and other pedicled flaps has then been made. In conclusion, it appears that this little-known procedure has definite advantages, and that it should be included in the range of surgical techniques that are available for soft tissue reconstruction in the case of elbow defects.

    Isolated angiitis of the central nervous system (IAC) is an idiopatic, recurrent vasculitis confined to the CNS involving small blood vessels. We describe the clinical, angiographic, and neuropathological data in two patients with IAC and delineate the main clinical and neuropathological features in both cases as well as the importance of a complete autopsy for discovering subclinical vasculitic lesions outside the CNS. Patient 1 concerned a 40 year-old-man that evolved for the last three years, initially with focal seizures, headache, and neurological focal deficits, later on the left sided hemihyposthesia and preferentially left parieto-occipital dysfunctions. He presented an oligoclonal band in CSF with slight hyperproteinorraquia and 25 lymphocytes. A cerebral angiography was compatible with angiitis and a leptomeningeal/cerebral biopsy showed lymphocytic vasculitis in the leptomeningeal and intraparenchymatous cerebral small vessels. These results lead to start a treatment with Cyclophosphamide associated to high dose of steroids. The patient clearly improved and now is almost asymptomatic. Patient 2 concerned a 67 year-old-man that evolved for 4 years with encephalic ischemic lesions distributed and confined throughout the brain stem and cerebellum, temporary remissions occurred and the patient required high-dose steroids and Cyclophosphamide to improve. Conventional and MRI angiographies only suggested the diagnosis that was confirmed at autopsy. The patient died after a massive pulmonary thromboembolism and a complete necropsic study showed abundant lymphocytic infiltrates, without granulomatous lesions, in the intraparenchymatous and leptomeningeal cerebral small vessels specially at the brain stem and cerebellar level where many demyelinated greyish areas and few infarctions were to be seen. The inflammatory cells were, in both cases, predominantly CD4+ T lymphocytes.(ABSTRACT TRUNCATED AT 250 WORDS)

  15. Informative Provenance for Repurposed Data: A Case Study using Clinical Research Data

    Directory of Open Access Journals (Sweden)

    Richard Bache

    2013-11-01

    Full Text Available The task repurposing of heterogeneous, distributed data for originally unintended research objectives is a non-trivial problem because the mappings required may not be precise. A particular case is clinical data collected for patient care being used for medical research. The fact that research repositories will record data differently means that assumptions must be made as how to transform of this data. Records of provenance that document how this process has taken place will enable users of the data warehouse to utilise the data appropriately and ensure that future data added from another source is transformed using comparable assumptions. For a provenance-based approach to be reusable and supportable with software tools, the provenance records must use a well-defined model of the transformation process. In this paper, we propose such a model, including a classification of the individual ‘sub-functions’ that make up the overall transformation. This model enables meaningful provenance data to be generated automatically. A case study is used to illustrate this approach and an initial classification of transformations that alter the information is created.

    Full Text Available Aim. To assess the prevalence of fear of hypoglycemia, its clinical features and influence on diabetes compensation.Materials and Methods. A cross-sectional study was conducted with 200 sequentially enrolled participants with type 2 diabetes mellitus (T2DM; n=139 and type 1 diabetes mellitus (T1DM; n=61. Patients were screened for psychiatric disorders with appropriate inventory and examined by a psychiatrist. Subjects identified as those with fear of hypoglycemia (n=12 formed the study group, while control group was assembled of individuals without phobic signs, matched for gender, age, type and duration of diabetes and concomitant psychiatric disorders.Results. Prevalence of fear of hypoglycemia was estimated at 6%, being consistently higher in patients with T1DM (16.1% vs. T2DM (1%; p=0.0002. Fear of hypoglycemia was associated with higher median HbA1c (9.4% [8.6 ; 9.9] vs. 8.2% [6.8 ; 9.3], p<0.05. These findings are in agreement with considerably higher prevalence of proliferative retinopathy (33% observed in study group (0% in control group, p<0.05. Phobic patients with T1DM had higher occurrence of ketoacidosis (41.7% of subjects, 7 cases than control subjects (16.6% of subjects, 2 cases. Similar trend was observed for severe hypoglycemic events. There was no significant difference between the groups in sensitivity to hypoglycemia, cognitive functions, educational level or social status. Patients with fear of hypoglycemia tend to regard hypoglycemia as primary, highly hazardous challenge of diabetes mellitus and perceive its symptoms as «extremely unpleasant». However, in this study phobic patients maintained the same level of self-monitoring as their control counterparts and demonstrated comparable knowledge of the causes of hypoglycemia. None of the participants reported a habit of carrying carbohydrates for hypoglycemia management.Conclusion. Fear of hypoglycemia is highly prevalent among patients with T1DM and is often

    Full Text Available The authors present a review of 21 cases with the diagnosis of type I amyloid neuropathy based on epidemiological data, clinical evolution and histopathological findings. They call attention to the possibility of cranial nerves involvement (hyposmia, diplopia, masseterian hypotrophy, peripheral facial paralysis, hypoacusis, dysphonia, laryngeal paralysis, dysphagia, and trapezium muscle hypotrophy, to the severeness of the digestive symptoms, to the precocity of the autonomic disorders, and to the rather high incidence (6 cases of heart involvement. The electromyography showed anterior horn involvement in 3 cases. The electrocardiography showed repolarization disorders in 11 cases, left ventricular overload in 6 cases and atrioventricular block in 5 cases. The serum proteins electrophoresis showed frequent abnormalities, but no typical curve could be obtained. The barium-contrasted X-rays of the gastrointestinal tract showed no anatomical lesions, but functional abnormalities (hypo or hypermotility were found in 14 examinations. The Schilling test showed impairment of vitamin B12 absorption in 50% of the cases. However, with the concomitant administration of intrinsic factor (3 cases there was improvement of its absorption. This proves that the gastric mucosa plays an important role in the disease malabsorption. The test with labeled-triolein showed slow absorption in 2 cases and steatorrhea in 3 (6 tests. For the confirmation of the amyloid deposits, the best histopathological procedure was nerve biopsy. In men, when the nerve biopsy was negative, testicular biopsy has shown to be a good option.

    Full Text Available Aims: To evaluate clinical profile and short-term outcome of psychogenic non-epileptic seizures (PNES in Indian adult population. Setting and Design: A prospective observational study, conducted at tertiary teaching institute at New Delhi. Materials and Methods: Sixty-three patients with confirmed PNES were enrolled. The diagnosis was based on witnessing the event during video-electroencephalography (Video-EEG monitoring. A detailed clinical evaluation was done including evaluation for coexistent anxiety or depressive disorders. Patients were divided into two groups on the basis of excessive or paucity of movements during PNES attacks. Patients were followed-up to 12 months for their PNES frequency. Statistical Analysis: Means and standard deviations were calculated for continuous variables. Chi-square and Students t-test were used to compare categorical and continuous variables respectively. Results: The mean age at onset of PNES was 25.44 years; with F:M ratio of 9.5:1. Coexistent epilepsy was present in 13 (20.63% cases. Twenty-two patients (44% with only PNES ( n = 50 had received antiepileptic drugs. Out of 63 patients of PNES 24 (38.1% had predominant motor phenomenon, whereas 39 (61.9% had limp attacks. The common features observed were pre-ictal headache, ictal eye closure, jaw clenching, resistant behavior, ictal weeping, ictal vocalization, and unresponsiveness during episodes. Comorbid anxiety and depressive disorders was seen in 62.3% and 90.16% patients, respectively. Short-term (6-12 months outcome of 45 patients was good (seizure freedom in 46.66% and >50% improvement in 24.44% cases. Conclusion: PNES is common, but frequently misdiagnosed and treated as epileptic seizures. A high index of suspicion is required for an early diagnosis. Proper disclosure of diagnosis and management of the psychiatric comorbidities can improve their outcome. Limitation: Limited sample size and change in seizures frequency as the only parameter for

    Monte Carlo (MC) methods are acknowledged as the most accurate technique to calculate dose distributions. However, due its lengthy calculation times, they are difficult to utilize in the clinic or for large retrospective studies. Track-repeating algorithms, based on MC-generated particle track data in water, accelerate dose calculations substantially, while essentially preserving the accuracy of MC. In this study, we present the validation of an efficient dose calculation algorithm for intensity modulated proton therapy, the fast dose calculator (FDC), based on a track-repeating technique. We validated the FDC algorithm for 23 patients, which included 7 brain, 6 head-and-neck, 5 lung, 1 spine, 1 pelvis and 3 prostate cases. For validation, we compared FDC-generated dose distributions with those from a full-fledged Monte Carlo based on GEANT4 (G4). We compared dose-volume-histograms, 3D-gamma-indices and analyzed a series of dosimetric indices. More than 99% of the voxels in the voxelized phantoms describing the patients have a gamma-index smaller than unity for the 2%/2 mm criteria. In addition the difference relative to the prescribed dose between the dosimetric indices calculated with FDC and G4 is less than 1%. FDC reduces the calculation times from 5 ms per proton to around 5 μs.

    Accurate assessment of obsessions and compulsions is a crucial step in treatment planning for Obsessive-Compulsive Disorder (OCD). In this clinical case study, we sought to determine if the use of Ecological Momentary Assessment (EMA) could provide additional symptom information beyond that captured during standard assessment of OCD. We studied three adults diagnosed with OCD and compared the number and types of obsessions and compulsions captured using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) compared to EMA. Following completion of the Y-BOCS interview, participants then recorded their OCD symptoms into a digital voice recorder across a 12-h period in reply to randomly sent mobile phone SMS prompts. The EMA approach yielded a lower number of symptoms of obsessions and compulsions than the Y-BOCS but produced additional types of obsessions and compulsions not previously identified by the Y-BOCS. We conclude that the EMA-OCD procedure may represent a worthy addition to the suite of assessment tools used when working with clients who have OCD. Further research with larger samples is required to strengthen this conclusion.

    Full Text Available Using a webinar format to connect to an off-site clinical microbiologist, we presented an interdisciplinary and interactive case study to undergraduate microbiology and anatomy and physiology students. After an introduction to pathophysiology and microbiology, the clinical microbiologist’s case study provided students with a unique look at real life problems. Our goal was to have students appreciate the interrelationship between microbiology and physiology, and to apply their knowledge of microbiology and physiology to solve the case study. The webinar format facilitated the delivery of the integrative learning experience to multiple classes and the off-site clinical microbiologist simultaneously. Students and faculty in both anatomy and physiology and microbiology undergraduate lectures and laboratory sessions can benefit from this approach.

  5. The epidemiology and clinical spectrum of melioidosis: 540 cases from the 20 year Darwin prospective study.

    Bart J Currie

    Full Text Available BACKGROUND: Over 20 years, from October 1989, the Darwin prospective melioidosis study has documented 540 cases from tropical Australia, providing new insights into epidemiology and the clinical spectrum. PRINCIPAL FINDINGS: The principal presentation was pneumonia in 278 (51%, genitourinary infection in 76 (14%, skin infection in 68 (13%, bacteremia without evident focus in 59 (11%, septic arthritis/osteomyelitis in 20 (4% and neurological melioidosis in 14 (3%. 298 (55% were bacteremic and 116 (21% developed septic shock (58 fatal. Internal organ abscesses and secondary foci in lungs and/or joints were common. Prostatic abscesses occurred in 76 (20% of 372 males. 96 (18% had occupational exposure to Burkholderia pseudomallei. 118 (22% had a specific recreational or occupational incident considered the likely infecting event. 436 (81% presented during the monsoonal wet season. The higher proportion with pneumonia in December to February supports the hypothesis of infection by inhalation during severe weather events. Recurrent melioidosis occurred in 29, mostly attributed to poor adherence to therapy. Mortality decreased from 30% in the first 5 years to 9% in the last five years (p<0.001. Risk factors for melioidosis included diabetes (39%, hazardous alcohol use (39%, chronic lung disease (26% and chronic renal disease (12%. There was no identifiable risk factor in 20%. Of the 77 fatal cases (14%, 75 had at least one risk factor; the other 2 were elderly. On multivariate analysis of risk factors, age, location and season, the only independent predictors of mortality were the presence of at least one risk factor (OR 9.4; 95% CI 2.3-39 and age ≥ 50 years (OR 2.0; 95% CI 1.2-2.3. CONCLUSIONS: Melioidosis should be seen as an opportunistic infection that is unlikely to kill a healthy person, provided infection is diagnosed early and resources are available to provide appropriate antibiotics and critical care.

    Full Text Available Bisphosphonates are the first-line drugs for osteoporosis, as well as for many types of cancer.One of their side-effects is osteonecrosis of the jaw, which has mainly been associated with their intravenous administration.This article features a clinical study of 21 cases of jaw osteonecrosis – 9 male and 12 female patients, with a mean age of 63 years and established bisphosphonate osteonecrosis of the jaws (BONJ, who were treated either conservatively or surgically in the past five years(2005-2010. Of these 21 patients, 17 were on bisphosphonates due to neoplastic disease and another 4 due to osteoporosis. Anti microbial chemotherapy and oral hygiene was the initial treatment for 10 patients with minor symptoms, while a broad spectrum of surgical treatments – from selected tooth extraction under prophylactic administration of antibiotics to marginal resection of necrotic bone – were used in 11 patients with severe bone exposure, infection and masticatory impairment. The majority of the patients who were surgically treated had a satisfactory outcome with no major complications, while 3 patients died from the main disease during the follow-up period.With in this context, we also present in detail the inclusion and taxonomy criteria for this particular disease, as well as our therapeutic protocols, and review the most significant contributions to the literature

    Aim: To present the neuroradiological and clinical findings of fourth-ventricular meningiomas to increase awareness of this entity. Materials and methods: The computed tomography (CT; n = 5), magnetic resonance imaging (MRI; n = 9) features and clinical presentations of 10 patients with pathologically documented fourth-ventricular meningiomas were retrospectively analysed. Results: All tumours appeared as well-demarcated masses in the fourth ventricle at CT and MRI. The tumour shape was round in eight cases (80%) and irregular in two cases (20%). The CT images of five cases showed predominantly isoattenuation in three cases and high attenuation in two cases, with a mean attenuation value of 52 HU. In addition, calcifications were seen in three cases. At MRI, nine masses were isointense (n = 6) or hypointense (n = 3) to grey matter on T1-weighted images and mildly hyperintense (n = 4), isointense (n = 3), hypointense (n = 1), and of mixed signal intensity (n = 1) on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images. Signal voids were visible in two cases. Enhancement after injection of contrast material was marked homogeneous (n = 5) or heterogeneous (n = 5) on CT or T1-weighted images. Three tumours had mild peritumoural oedema. Three tumours were associated with obstructive hydrocephalus. The pathological subtype of the 10 meningiomas was fibromatous (n = 5), atypical (n = 2), and one each of transitional, psammomatous, and clear-cell type. Conclusion: Although fourth-ventricular meningioma is quite rare, it should be considered in differential diagnosis of neoplasms within the fourth ventricle. The relatively typical radiological appearance, combined the age and sex of patients, can suggest the diagnosis of fourth-ventricular meningioma.

    Full Text Available Hydatid cyst of the adrenal gland (HCAG is an exceptional occurrence. We report our experience of six cases of HCAG and discuss the diagnosis and treatment of this hydatid localization. We retrospectively reviewed and analyzed the clinical files of six patients admitted to our institution from January 1990 to December 2000 for HCAG. Patients varied in age from 24—59 years. They were five males and one female. One patient had a history of pulmonary hydatidosis treated surgically 10 years previously. Five patients presented with lumbar pain and one patient had bouts of hypertension, headache, and palpitation. Physical examination was normal except in one patient who was hypertensive. Preoperative diagnosis was highly suggested by ultrasonography. CT scan performed in all cases clearly showed the relationship of the cyst with adjacent organs. Serology tests were positive in two cases. One patient had elevated urine VMA and was operated on with the diagnosis of cystic phaeochromocytoma. All six patients were operated on and had either an adrenalectomy (two cases or partial pericystectomy (four cases. In one case, partial pericystectomy was conducted through a retroperitoneal laparoscopic approach. The hydatid nature of the cyst was confirmed pathologically. All patients had a smooth postoperative course with no cystic recurrence on follow-up. The diagnosis of HCAG is based mainly on ultrasonography and CT scan. Surgery with either partial or total excision of the cyst, with or without preservation of the adrenal gland, is the treatment of choice.

  13. Topological characteristics of brainstem lesions in clinically definite and clinically probable cases of multiple sclerosis: An MRI-study

    International Nuclear Information System (INIS)

    Disseminated lesions in the white matter of the cerebral hemispheres and confluent lesions at the borders of the lateral ventricles as seen on MRI are both considered acceptable paraclinical evidence for the diagnosis of multiple sclerosis. Similar changes are, however, also found in vascular diseases of the brain. We therefore aimed at identifying those additional traits in the infratentorial region, which in our experience are not frequently found in cerebrovascular pathology. We evaluated MR brain scans of 68 patients and found pontine lesions in 71% of cases with a clinically definite diagnosis (17 out of 24) and in 33% of cases with a probable diagnosis (14 out of 43). Lesions in the medulla oblongata were present in 50% and 16%, respectively, and in the midbrain in 25% and 7%, respectively. With rare exceptions all brainstem lesions were contiguous with the cisternal or ventricular cerebrospinal fluid spaces. In keeping with post-mortem reports the morphological spectrum ranged from large confluent patches to solitary, well delineated paramedian lesions or discrete linings of the cerebrospinal fluid border zones and were most clearly depicted from horizontal and sagittal T2 weighted SE-sequences. If there is a predilection for the outer or inner surfaces of the brainstem, such lesions can be considered an additional typical feature of multiple sclerosis and can be more reliably weighted as paraclinical evidence for a definite diagnosis.

    Diarrhoeal diseases are a common cause of morbidity and are associated with mortality in HIV-infected populations. Little is known about the contribution of clinical and socio-environmental factors to the risk of diarrhoea in these populations in rural sub-Saharan Africa. We conducted a case-control study of people attending a rural HIV clinic with an episode of diarrhoea in Bushbuckridge, South Africa. Cases were defined as HIV-positive adults with symptoms of diarrhoea before or after initiation of antiretroviral therapy (ART). Controls without diarrhoea were randomly selected from clinic attendees. Structured questionnaires and case-file reviews were undertaken to describe clinical and socioenvironmental risk factors. We recruited 103 cases of diarrhoea from 121 patients meeting case definitions. Cases were more likely to be women (P = 0.013), aged over 45 years (P = 0.002), divorced or separated (P = 0.006), have limited formal education (P = 0.003), have inadequate access to sanitation facilities (P = 0.045), have water access limited to less than three days per week (P = 0.032) and not yet initiated on ART (P analysis, diarrhoea remained associated with female gender (adjusted odds ratio [aOR]: 2.02, 95% CI 1.10-3.73), older age (aOR: 6.31, 95% CI 1.50-26.50), limited access to water (aOR: 2.66, 95% CI 1.32-5.35) and pre-ART status (aOR: 5.87, 95% CI 3.05-11.27). Clinical and socio-environmental factors are associated with occurrence of diarrhoeal disease among rural HIV patients in South Africa. Further intervention research is urgently needed, combining community- and clinic-based approaches, to improve access to water, sanitation and ART for rural areas with high HIV prevalence, along with structural interventions to address gender inequities.

  16. Reducing medication errors and increasing patient safety: case studies in clinical pharmacology.

    Benjamin, David M

    2003-07-01

    Today, reducing medication errors and improving patient safety have become common topics of discussion for the president of the United States, federal and state legislators, the insurance industry, pharmaceutical companies, health care professionals, and patients. But this is not news to clinical pharmacologists. Improving the judicious use of medications and minimizing adverse drug reactions have always been key areas of research and study for those working in clinical pharmacology. However, added to the older terms of adverse drug reactions and rational therapeutics, the now politically correct expression of medication error has emerged. Focusing on the word error has drawn attention to "prevention" and what can be done to minimize mistakes and improve patient safety. Webster's New Collegiate Dictionary has several definitions of error, but the one that seems to be most appropriate in the context of medication errors is "an act that through ingnorance, deficiency, or accident departs from or fails to achieve what should be done." What should be done is generally known as "the five rights": the right drug, right dose, right route, right time, and right patient. One can make an error of omission (failure to act correctly) or an error of commission (acted incorrectly). This article now summarizes what is currently known about medication errors and translates the information into case studies illustrating common scenarios leading to medication errors. Each case is analyzed to provide insight into how the medication error could have been prevented. "System errors" are described, and the application of failure mode effect analysis (FMEA) is presented to determine the part of the "safety net" that failed. Examples of reengineering the system to make it more "error proof" are presented. An error can be prevented. However, the practice of medicine, pharmacy, and nursing in the hospital setting is very complicated, and so many steps occur from "pen to patient" that there

  17. Comparative study on cases of vertigo and dizziness in the emergency room and otorhinolaryngological clinic

    International Nuclear Information System (INIS)

    We recently studied the characteristics of vertigo and dizziness in 197 patients who first visited the emergency room (ER group) and in 288 patients who first visited the otorhinolaryngological clinic of Minoh City Hospital (ENT group) between January 1 and December 31 of 2009. The ER group can be regarded as representing the hyperacute phase and the ENT group as representing the acute to chronic phase. These two groups were completely distinct. We also subdivided these groups into the high risk subgroup (H subgroup) for cases with the underlying diseases of diabetes mellitus, hypertension, cerebrovascular disease and hyperlipidemia, and the normal subgroup (N subgroup).Comparison of the two groups showed that, in the ER group, a significantly larger numbers of patients had symptoms of peripheral vestibular origin except for benign paroxysmal positional vertigo (BPPV) and Meniere's disease, and a significantly larger number of patients had symptoms of unknown origin in the ENT group. Half of this group may be accounted for by patients with symptoms of peripheral vestibular origin except for BPPV and Meniere's disease in the ER group. In 8 out of 158 patients of the ER group and 1 out of 122 patients of the ENT group, cerebral lesions were not found on CT images but were found with MRI. Careful investigation is necessary in the patients with normal CT findings. Central vestibular lesions were found in 7 out of 197 patients (3.5%) of the ER group and 5 out of 288 patients (1.7%) of the ENT group. The incidence of central lesions tended to be higher in the ER group than in the ENT group. There was no significant difference in the incidence of central lesion among the H and N subgroups of both groups. Careful investigation of the central vestibular lesion is also necessary in the N subgroup. (author)

    As a rare multisystem congenital anomaly disorder, Cornelia de Lange syndrome (CdLS) is featured by delayed growth and development, distinct facial dimorphism, limb malformations and multiple organ defects. CdLS is a genetic syndrome affecting 1/10000-1/60000 neonates with unknown genetic basis. Delayed growth and development, hirsute, structural anomalies of the limbs and distinct facial dimorphism are considered as its main clinical characteristics. Introducing CdLS cases of different ethnic backgrounds could add distinctions to the phenotypic picture of the syndrome and be useful in diagnosis. Early diagnosis and decreased death rates are achievable through enhanced awareness on this syndrome. We present here a 45-day-old girl, as the first case of Cornelia in Golestan (Northern Iran), referred to our hospital with the symptoms as mentioned above. PMID:27042551

  19. Studies on diagnosis of lung emphysema by CT image using experimental models and clinical cases

    International Nuclear Information System (INIS)

    Since the detailed report between the degree of functional disorder in lung emphysema and the analysis of CT image is quite unknown, the present study was attempted to produce the experimental model of lung emphysema with various stages by the administration of papain to the focal lobe in canine lung. Using this model or clinical lung emphysema, the relationship between the degree of destruction of alveolar walls, clinical pulmonary functions and CT images was investigated. CT scan was performed at the level of 50% vital capacity in both experimental models and clinical subjects by using spirometric gating CT. CT density histogram was obtained from CT image which was produced by using the developed software for this purpose. Densitometric parameters, such as mean CT value, %LAA, the peak in the histogram and 5% tile were selected from CT image. Papain solution of 5 mg/kg body weight was cumulatively administered to the left lower lobe in canine lung, resulting in the destruction of lung alveolar walls in parallel to the increasing dosage of papain. There was a significant correlation between not only the increasing dosage of papain, but also %FEV 1.0 and CT densitometric parameters, indicating that the histological changes of alveolar walls and the lung function in lung emphysema could be estimated by analysis of CT image. These experimental and clinical studies suggest that the analysis of CT image can reflect the pathophysiological changes in the lung and be useful for precise clinical diagnosis of lung emphysema.

    Full Text Available Background: Prolonged and continuous use of topical steroids leads to rosacea-like dermatitis with variable clinical presentations. Aims: To study the various clinical presentations of patients with topical corticosteroid-induced rosacea-like dermatitis (TCIRD, who had a history of prolonged and repeated use of topical steroids for reasons other than the known disease entities. Methods: A total of 110 patients were enrolled for the study over a period of 2 years, excluding all those with the known disease entity in which topical steroids were commonly used. Detailed history which also included the source and the type of topical steroid use was taken along with clinical examination. Results: There were 12 males and 98 females with their age ranging from 18 to 54 years. The duration of topical steroid use ranged from 4 months to 20 years. The most common clinical presentation was diffuse erythema of the face. Most of the patients had rebound phenomenon on discontinuation of the steroid. The most common topical steroid used was Betamethasone valerate, which could be due to its easy availability and low cost. Conclusion: Varied clinical presentations are seen with prolonged and continuous use of topical steroids. The treatment of this dermatitis is difficult, requiring complete cessation of the offending steroid, usually done in a tapering fashion.

    Since the detailed report between the degree of functional disorder in lung emphysema and the analysis of CT image is quite unknown, the present study was attempted to produce the experimental model of lung emphysema with various stages by the administration of papain to the focal lobe in canine lung. Using this model or clinical lung emphysema, the relationship between the degree of destruction of alveolar walls, clinical pulmonary functions and CT images was investigated. CT scan was performed at the level of 50% vital capacity in both experimental models and clinical subjects by using spirometric gating CT. CT density histogram was obtained from CT image which was produced by using the developed software for this purpose. Densitometric parameters, such as mean CT value, %LAA, the peak in the histogram and 5% tile were selected from CT image. Papain solution of 5 mg/kg body weight was cumulatively administered to the left lower lobe in canine lung, resulting in the destruction of lung alveolar walls in parallel to the increasing dosage of papain. There was a significant correlation between not only the increasing dosage of papain, but also %FEV 1.0 and CT densitometric parameters, indicating that the histological changes of alveolar walls and the lung function in lung emphysema could be estimated by analysis of CT image.

    Objectives Pancreatic neuroendocrine tumors (PNETs) are uncommon, and little is known about their risk factors and association with other cancers. We evaluated whether risk factors known to be associated with pancreatic adenocarcinoma are also associated with PNETs: smoking, alcohol use, family history of PNET and other cancers, and personal history of diabetes as potential risk factors. Methods Patients with PNETs seen at Mayo Clinic Rochester between 2000 and 2011 were compared to controls seen for a general medical evaluation. Patients and controls completed the same questionnaires. After excluding insulinoma and high-grade PNETs, 355 cases were evaluated, and 309 were matched to 602 controls (2:1) on age, sex, and region of residence. Results Personal smoking history was not associated with PNETs. Alcohol use was less common among cases (54% vs. 67%, p<0.001). Cases were more likely to report a family member with sarcoma (p=0.02), PNET (p=0.02), gall bladder cancer (p=0.02), ovarian cancer (p=0.04) and gastric cancer (p=0.01). There was no association with other cancers in family members. Diabetes was more commonly reported by cases than controls (19% vs. 11%, p<0.001). Conclusions With the exception of diabetes, risk factors that are associated with pancreatic adenocarcinoma are not risk factors for PNETs. PMID:25291526

    We report 9 cases of cerebellar contusion from April 2011 to September 2014 at our department. Frequency, clinicoradiological findings, mechanism of injury, treatments, and outcomes were retrospectively analyzed. Of 239 head injury cases admitted to our department during the same period, 9(3.8%)were diagnosed as cerebellar contusion. Among these 9 cases, 7 were men, and 2 were women. The patient age ranged from 12 to 83 years with a mean age of 64.7 years. The mechanism of injury was traffic accident in one patient, and fall in 8. All cases were associated with direct head trauma to the occiput, and radiographic studies showed occipital bone fracture in 8 cases. Six cases were managed conservatively. Three cases underwent suboccipital craniectomies and clot evacuations. Glasgow Outcome Scale(GOS)score at discharge were Good Recovery(GR)in 2, Moderate Disability(MD)in 2, Severe Disability(SD)in 3, Vegetative State(VS)in 1, and Dead(D)in 1. GOS scores in surgically treated cases were GR in 1, SD in 1, and VS in 1. Supratentorial severe traumatic lesions were concomitant with poor prognosis. Coup injury was a significant cause of cerebellar contusion. External decompression and clot evacuation were useful in patients who suffered severe cerebellar contusion;however, concomitant supratentorial lesions influenced the prognosis.

    To observe the clinical therapeutic effects of electro-acupuncture therapy for mental depression, 30 cases were treated by electro-acupuncture on Baihui (GV20), Yintang (EX-HN3) and the differential points.Maprotiline was used in the control group of 31 cases. After the treatment, the scores in HAMD for both groups were found to be obviously decreased as compared with those before the treatment (P<0.01),without significant between-group differences (P>0.05). The total effective rate in the treatment group was 96.7%, and that of the control group was 90.3%, showing no significant between-group differences (P>0.05). After the treatment, the two groups all showed obvious decrease in the TCM symptomatic integrals (P<0.01), with significant between-group differences (P<0.05), the integral of the treatment group showing obvious superiority to that of the control group. And the decrease of the Asberg scores testing the side effect of antidepressants of the treatment group was obviously superior to that of the control group. After the treatment, the cortisol (CORT) content and the endothelin-1 (ET-1) content of the two groups were all obviously decreased (P<0.01), and basically turned to normal, without significant between-group differences (P>0.05). Conclusion: Electro-acupuncture therapy can produce the same clinical therapeutic effect as that produced by the tetracyclic drug maprotiline, giving less side effect and better symptomatic improvement.

    Full Text Available Abstract Background Small private-sector health care providers can play an important role in meeting the developing country health care needs, but a lack of credit can prove major constraint to small-provider expansion. This study examines the potential of small, microfinance loans to strengthen the private health sector and improve access to quality preventive and curative health services in Uganda. Methods This study estimates logistic regressions using 2,387 client exit interviews to assess the impact of microfinance loans on perceived quality and the viability and sustainability of small, private clinics. Results The study finds perceived quality improved with loan recipients' clients being more likely to choose clinics on the basis of drug availability, fair charges, cleanliness, and confidentiality. In addition, the assessment found evidence of increased client flows, but the changes produced mixed results for sustainability with respondents being only half as likely to "always" visit a particular clinic. Conclusion The results indicate that the microfinance program improved perceived quality at loan recipient clinics, especially as reliable drug outlets.

    The role of environmental risk factors in clinical malaria has been studied mainly in Africa and Asia, few investigations have been carried out in Latin America. Field observations in northern coastal Peru, where the prevalence of malaria is high during the agricultural season, suggested that the risk of disease varied according to the characteristics of the house and the house environment. Environmental determinants of the risk of clinical malaria were therefore investigated through a case-control study: 323 clinical cases of malaria, recruited through community-based active case-finding, and 969 age-, sex- and village-matched controls were recruited into the study over a period of 12 months ending June 1997. Residual spraying of houses in the previous 6 months, living more than 100 m from a canal, a level of education equal to primary school or above and working in agriculture conferred significant protection from the risk of developing clinical malaria. The presence of spaces between the wall and roof in the subject's bedroom (eaves) and a house aged > 4 years statistically significantly increased the risk of disease. Based on these results we discuss possible control measures for malaria in this area of the country.

    Full Text Available OBJECTIVES AND INTRODUCTION: Medullary thyroid carcinoma, a neoplasia of intermediate prognosis and differentiation, does not always respond predictably to known treatments. This study aimed to correlate the clinical progression of surgically treated patients with clinical and pathological data. METHODS: A total of 53 patients were followed for 75 months (mean average in tertiary-care hospital. The clinical status of patients at the end of the study period was characterized to determine correlations with a range of disease aspects. A value of p < 0.05 was considered statistically significant. RESULTS: Twenty-two patients (41.5% were alive and disease-free at the end of the follow-up period; twenty-three patients (43.4% had persistent disease; and eight patients (15.1% had recurrent disease. Four patients (7.6% died from medullary thyroid carcinoma with clinical and/or imaging evidence of neoplasia. The following aspects demonstrated statistically significant correlations with the final medical condition: positive initial cervical examination (p = 0.002; neoplastic extensions to the thyroid capsule (p = 0.004 and adjacent tissues (p = 0.034; cervical lymph node metastases (p < 0.001; diameter of neoplasia (p = 0.018; TNM (tumor, node and metastasis Stage (p = 0.001 and evidence of distant and/or cervical diseases in the absence of a cure (p = 0.011. Through logistic regression, the presence of cervical lymph node metastases was considered an independent variable (p < 0.001. CONCLUSIONS: Clinical and pathological aspects of patients with surgically treated medullary thyroid carcinomas are predictors of disease progression. Specifically, even treated cervical lymph node metastases are significantly correlated with disease progression.

  18. Evaluation of an artificial intelligence guided inverse planning system: Clinical case study

    International Nuclear Information System (INIS)

    Purpose: An artificial intelligence (AI) guided method for parameter adjustment of inverse planning was implemented on a commercial inverse treatment planning system. For evaluation purpose, four typical clinical cases were tested and the results from both plans achieved by automated and manual methods were compared. Methods and materials: The procedure of parameter adjustment mainly consists of three major loops. Each loop is in charge of modifying parameters of one category, which is carried out by a specially customized fuzzy inference system. A physician prescribed multiple constraints for a selected volume were adopted to account for the tradeoff between prescription dose to the PTV and dose-volume constraints for critical organs. The searching process for an optimal parameter combination began with the first constraint, and proceeds to the next until a plan with acceptable dose was achieved. The initial setup of the plan parameters was the same for each case and was adjusted independently by both manual and automated methods. After the parameters of one category were updated, the intensity maps of all fields were re-optimized and the plan dose was subsequently re-calculated. When final plan arrived, the dose statistics were calculated from both plans and compared. Results: For planned target volume (PTV), the dose for 95% volume is up to 10% higher in plans using the automated method than those using the manual method. For critical organs, an average decrease of the plan dose was achieved. However, the automated method cannot improve the plan dose for some critical organs due to limitations of the inference rules currently employed. For normal tissue, there was no significant difference between plan doses achieved by either automated or manual method. Conclusion: With the application of AI-guided method, the basic parameter adjustment task can be accomplished automatically and a comparable plan dose was achieved in comparison with that achieved by the manual

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

    Driven by the Health Information Technology for Economic and Clinical Health (HITECH) Act large numbers of physicians and hospitals are now implementing electronic health records (EHR) with the general expectation that such systems will improve the quality, safety and efficiency of health care services. Studies of conversions from paper to electronic records paint a mixed picture with healthcare providers pleased with some aspects of their EHRs but dissatisfied with others. These prior studies focused on conversions from paper to electronic records. Many provider impressions, therefore, may have been influenced by reactions to the process of being required to change well established patterns. In order to help separate such reactions from true evaluations of the efficacy of the EHR, we decided to survey the providers in a new health center. To insure that the information gathered was not merely anecdotal, we used a well-established format starting with a semi-structured interview which facilitates analysis and recognition of major themes. We included questions around several important areas including workflow, communication, patient satisfaction, productivity, documentation, and quality of care. Ten main themes emerged: impeding patient flow, hindering communication in office, improving communication after the visit, improving tracking of patient care, spending less time with patients, requiring more training, wanting more features, diminishing productivity, appreciating benefits of templates, and enhancing internal communication. The need for better training appeared to be of especially high importance as it impacted several of the other themes. We believe that our study helps validate the similar concerns expressed in studies of transitions from paper to electronic record systems. Our method may be generally useful to other clinics because it facilitates timely recognition of themes, both positive and negative, that clinicians and clinic managers would want to

    Objective. The aim of the study was to evaluate the prevalence of and risk factors for lower limb amputation in a specialist foot clinic-based setting. Methods. A retrospective quantitative study was conducted, using clinical and biochemical profiles of diabetic foot patients attending the High Risk Foot Clinic at The Townsville Hospital, Australia, between January 1, 2011, and December 31, 2013. Results. The total study sample included 129 subjects, comprising 81 males and 48 females with M : F ratio of 1.7 : 1. Twenty-three subjects were Indigenous Australians, representing 17.8% of the study population. The average age of the cohort was 63.4 years ± 14.1 years [CI 90.98–65.89]. Lower limb amputation was identified as a common and significant outcome (n = 44), occurring in 34.1%, more commonly amongst the Indigenous Australians (56.5% versus 29.2%; p = 0.94, OR 0.94). Risk factors most closely associated with amputation included diabetic retinopathy (p = 0.00, OR 4.4), coronary artery bypass graft (CABG) surgery (p = 0.01, OR 4.1), Charcot's arthropathy (p = 0.01, OR 2.9), and Indigenous ethnicity (p = 0.01, OR 3.4). Although average serum creatinine, corrected calcium, and glycosylated haemoglobin A1c (Hba1c) levels were higher amongst amputees they were statistically insignificant. Conclusions. Lower limb amputation is a common outcome and linked to ethnicity and neurovascular diabetic complications amongst subjects with diabetic foot ulcer. Further research is needed to identify why risk of lower limb amputation seems to differ according to ethnicity.

    Full Text Available Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation.

    Full Text Available OBJECTIVES: This study was conducted to know the distribution of intestinal tuberculosis in various age groups and sex, and to study common presenting symptoms and frequency of involvement of different sites in intestinal tuberculosis. METHODS: The study reports 50 cases of intestinal tuberculosis admitted at tertiary care hospital, during 2007 to 2009, who required surgery . RESULTS: More than 50% patients were between 11 to 30 years of age. Males and females equally affected by the condition . Fever, anorexia, vomiting and weight loss are common symptoms along with abdominal pain being present in all patients. Ileum was most commonly affected part of the intestine, while rectum was never seen to be involved in any cases in the study. CONCLUSION: As the condition affects children and adolescent more frequently, prevention, early diagnosis and proper medical treatment in this age group are very important factors to reduce the disease burden to society. As ileum was most commonly affected part, its surgical removal may lead to problems relating with malnutrition and needs long term follow up and further studies to know the long term consequences of surgery for the condition.

    We retrospectively analyzed 297 proven cases of Philodryas patagoniensis bites admitted to Hospital Vital Brazil (HVB), Butantan Institute, São Paulo, Brazil, between 1959 and 2008. Only cases in which the causative animal was brought and identified were included. Part of the snakes brought by the patients was still preserved in the collection maintained by the Laboratory of Herpetology. Of the 297 cases, in 199 it was possible to describe the gender of the snake, and seventy three (61.3%) of them were female. The length of snakes (snout-vent length) ranged from 160 to 1080 mm. In 117 snakes their state of preservation enabled the dissection and examination of their stomach contents. The stomach was empty in 106 snakes (89.1%). Most bites occurred in the seasons of spring and summer (n = 196, 66.0%) and during warmer periods of the day. The mean age of the victims was 24.1 +/- 15.1 years old and 206 (69.4%) patients were men. Around 92% of the patients sought medical care within 6 h after the bite. Both lower (n = 188, 63.3%) and upper limbs (n = 102, 34.3%) were most frequently bitten, especially the feet and hands (n = 205, 69.0%). The local clinical manifestations were pain (n = 151, 50.8%), transitory bleeding (n = 106, 35.7%), erythema (n = 47, 15.8%) and edema (n = 39, 13.1%). Ecchymosis was not observed. Only 7 (2.4%) patients reported systemic symptoms characterized by mild dizziness and 88 patients (29.6%) showed no evidence of envenoming. The whole blood clotting time was performed in 76 (25.6%) patients on admission and all of them had coagulable blood. Supportive treatment was offered to only 13.4% of patients, namely administration of antihistamines (n = 19, 6.4%) and analgesics (n = 12, 4.1%). Eight patients (2.7%) were mistreated with Bothrops antivenom before their admission to HVB. No sequels or relevant complications were observed in patients, and the prognostic was benign. Therefore, although P. patagoniensis accidents can cause mild local

    Lujan, Josefina; Vasquez, Rebecca

    2010-07-01

    The Institute of Medicine, Office of Minority Health, and the Health Resources and Services Administration have called for culturally competent teaching methods to promote the success of Hispanic nursing students. The article responds to this call by analyzing an innovative clinical practicum teaching method, the Scaffolding Clinical Model, in relation to the cultural competence needs of Hispanic nursing students. The analysis is presented through a case study of a cohort of predominantly (90%) Hispanic baccalaureate nursing students at a university on the United States-Mexico border. The cultural competence of the Scaffolding Clinical Model is analyzed by identifying how well it acknowledges and fosters the application of the four metaparadigms of Hispanic culture--conquest, collectivism, familism, and personalism--for Hispanic students. The metaparadigms are described and specific examples are offered about how the Model promotes application of the metaparadigms to accomplish cultural competence for Hispanic students. Recommendations for educators are also presented.

  9. A clinical study of 37 cases of major salivary gland carcinomas

    International Nuclear Information System (INIS)

    Thirty-seven cases of major salivary gland carcinomas, treated in our hospital during the past 16 years from July 1995 to June 2011, were studied and reviewed histopathologically and statistically. They comprised 27 cases with parotid carcinomas and 10 cases with submandibular carcinomas. Thirty-five patients had undergone surgery, followed by chemotherapy in 7 patients and radiation therapy in 20. Because of the advanced ages of two patients in their 90's with submandibular carcinoma, they were treated with radiation alone. The mean age of the group was 62.1 years. There was no difference based on sex and the side of occurrence. The mean duration of the complaint was 33.6 months, and the mean tumor diameter was 34.6 mm. The results of cytological examinations from 35 cases with fine-needle aspiration biopsy delivered a sensitivity of 62.9% and a false-negative rate of 37.1%. Histopathological findings revealed the numbers of carcinoma ex pleomorphic adenoma as the greatest in all cases, salivary duct carcinoma in parotid carcinomas and also carcinoma ex pleomorphic adenoma in submandibular carcinomas. The mean operation time was 171.7 minutes and the mean intraoperative blood loss was 125.5 ml. In both parameters there was a statistically significant correlation. The complication with the highest postoperative rate was facial nerve palsy (37%). The 5-year cause-specific survival rate (CSS) was 78.5% in all cases, and 80.7% in parotid carcinomas and 72.9% in submandibular carcinomas, although these latter rates were without statistical significance. On the other hand according to the classifications of the stage of the cancer, the 5-year CSSs were 100% for Stage I, 80% for Stage II, 50% for Stage III, and 71.2% for Stage IV. Furthermore patients with parotid carcinomas with facial nerve palsy at the first time of diagnosis or in the category of the high malignancy group revealed significantly bleaker survival rates than those without.

    1992-05-01

    Non-attendance at out-patient clinics is a persistent, worldwide problem. In contrast with previous research, a qualitative approach was used in this study to examine reasons for non-attendance at out-patient clinics in one Belfast hospital, by exploring perspectives of general practitioners (GPs), hospital staff and defaulters. Findings revealed conflicts of opinion between GPs and hospital staff on appropriate management of certain medical and postnatal patients. Patients' reasons for defaulting were wide-ranging; however, 32% of those interviewed did not attend, or were recorded as non-attenders, for reasons relating to inefficient hospital administration. It is concluded that the causes of non-attendance were multifactorial, and non-attenders could not be stereotyped as irresponsible. Suggested measures to alleviate the problem include discussion between groups of professionals on responsibility for care of medical and postnatal patients, increased negotiation between patients and physicians in order to develop agreed programmes of care, and, where possible, a shifting of the onus of responsibility for making and cancelling appointments onto patients.

    For cultural reasons modern contraception has been slow to gain acceptance in Ethiopia. Knowledge about contraception and abortion is still limited in many family and community settings in which it is socially disapproved. By 1990 only 4% of Ethiopian females aged 15-49 used contraception. Little is known of sexually transmitted disease (STD) prevalence in family planning (FP) attenders in Africa in general and Ethiopia in particular, even though attenders of family planning clinics (FPCs) are appropriate target groups for epidemiological studies and control programmes. A study of 2111 women of whom 542 (25.7%) attended FPCs in Addis Ababa showed utilisation rates to be highest in women who were: Tigre (33%) or Amhara (31%), aged 20-34 years (30%), age 16 or older at first marriage/coitus (28%:38% in those first married after 25 years); who had a monthly family income of 10 Ethiopian Birr (EB) or more (33%:36% for those with income 100-500 EB), three or more children (37%), more than five lifetime husbands/sexual partners (39%); or were bargirls (73%) or prostitutes (43%). The seroprevalence rates for all STDs, higher in FPC attenders compared with other women, were syphilis (TPHA) 39%, Neisseria gonorrhoeae 66%, genital chlamydia 64%, HSV-2 41%, HBV 40% and Haemophilus ducreyi 20%. Only 4% of FPC attenders had no serological evidence of STD: 64% were seropositive for 3 or more different STD. Clinical evidence of pelvic inflammatory disease (PID) was also more common in the FPC attenders (54%), 37% having evidence of salpingitis. The FPC provides a favourable setting for screening women likely to have high seroprevalence of STD, who for lack of symptoms will not attend either an STD clinic nor a hospital for routine check up. We recommend that measures be taken to adequately screen, treat and educate FPC attenders, their partners, and as appropriate and when possible their clients, in an attempt to control STDs and ultimately HIV in the community.

    Despite the burgeoning scientific literature examining the sluggish cognitive tempo (SCT) construct, very little is known about the clinical presentation of SCT. In clinical cases where SCT is suspected, it is critical to carefully assess not only for attention-deficit/hyperactivity disorder (ADHD) but also for other comorbidities that may account for the SCT-related behaviors, especially internalizing symptoms and sleep problems. The current case study provides a clinical description of SCT in a 7-year-old girl, offering a real-life portrait of SCT while also providing an opportunity to qualitatively differentiate between SCT and ADHD, other psychopathologies (e.g. depression, anxiety), and potentially related domains of functioning (e.g. sleep, executive functioning [EF]). "Jessica" was described by herself, parents, and teacher as being much slower than her peers in completing schoolwork, despite standardized testing showing Jessica to have above average intelligence and academic achievement. Jessica's parents completed rating scales indicating high levels of SCT symptoms and daytime sleepiness, as well as mildly elevated EF deficits. More research is needed to determine how to best conceptualize, assess, and treat SCT, and Jessica's case underscores the importance of further work in this area. PMID:25326531

  15. Study on the clinical usefulness of magnetic resonance imaging in cases of multiple cerebral infarction

    International Nuclear Information System (INIS)

    The clinical significance of MRI in thrombotic multiple cerebral infarction was examined in 9 patients having recent lacunar stroke. Recent infarct was identified on Gd-enhanced MRI in 4 patients. For patients multiple small infarction, Gd-enhanced MRI made it possible to differentiate recent from other lesions. To clarify the significance of periventricular high intensity lesion (PVH) on T2-weighted MRI, hemodynamic and neuropsychologic examinations were carried out in 41 patients with multiple cerebral infarction. All the patients had PVH, which was classified into three grades as follows: grade I (n=16) showing only a thin high intensity band along the body of lateral ventricles; grade 2 (n=15) showing a definite high intensity area around the lateral ventricles; grade 3 (n=10) showing diffuse thick and irregular foci around the whole ventricle. In these patients, rCBF was measured by 133Xe inhalation methods. Initial slope index was significantly higher in patients with grade 3 than those with grade I. Mini-mental state test score was significantly higher in patients with grade l than those with grade 2 and 3. Progression of PVH may be related with the reduction of the cerebral circulation and mental function in cases of multiple cerebral infarction. Ischemic and hemorrhagic lesions can be distinguished by MRI, because old intracerebral hemorrhage appear as hypointensity areas with or without hyperintensity area on T2w images. In 92 patients with multiple infarction, MRI was used to evaluate the incidence and distribution of coexisting old intracerebral hemorrhage. Old hemorrhage were found in 15 patients (16.3%). locating the site where hypertensive hemorrhage commonly occurred. High-field MRI is useful for assessing the coexistence of hemorrhage in hypertensive patients with multiple cerebral infarction. (N.K.)

    Full Text Available BACKGROUND: Dengue has emerged as the most important vector-borne viral disease in tropical areas. Evaluations of the burden and severity of dengue disease have been hindered by the frequent lack of laboratory confirmation and strong selection bias toward more severe cases. METHODOLOGY: A multinational, prospective clinical study was carried out in South-East Asia (SEA and Latin America (LA, to ascertain the proportion of inapparent dengue infections in households of febrile dengue cases, and to compare clinical data and biological markers from subjects with various dengue disease patterns. Dengue infection was laboratory-confirmed during the acute phase, by virus isolation and detection of the genome. The four participating reference laboratories used standardized methods. PRINCIPAL FINDINGS: Among 215 febrile dengue subjects-114 in SEA and 101 in LA-28 (13.0% were diagnosed with severe dengue (from SEA only using the WHO definition. Household investigations were carried out for 177 febrile subjects. Among household members at the time of the first home visit, 39 acute dengue infections were detected of which 29 were inapparent. A further 62 dengue cases were classified at early convalescent phase. Therefore, 101 dengue infections were found among the 408 household members. Adding these together with the 177 Dengue Index Cases, the overall proportion of dengue infections among the study participants was estimated at 47.5% (278/585; 95% CI 43.5-51.6. Lymphocyte counts and detection of the NS1 antigen differed significantly between inapparent and symptomatic dengue subjects; among inapparent cases lymphocyte counts were normal and only 20% were positive for NS1 antigen. Primary dengue infection and a specific dengue virus serotype were not associated with symptomatic dengue infection. CONCLUSION: Household investigation demonstrated a high proportion of household members positive for dengue infection, including a number of inapparent cases, the

    Full Text Available Overestimation of the efficacy of conservative treatment of spine injuries children often leads to unsatisfactory long-term results. The effective correction of post-traumatic spinal column deformities occurs in patients who undergo the operation in the early post-traumatic period. While choosing treatment strategies for children, higher reparative opportunities, which provide early fracture consolidation, including those in faulty positions, should be considered. This study presents a case of surgical treatment for uncomplicated injury of the thoracic and lumbar spine, with long-term compression fragmental fracture of the L1 vertebra body in a 12-year-old child. Due to the long-standing character of the injury right thoraco-frenotomy was conducted with partial L1 vertebral body and resection of the adjacent discs, deformity correction of the thoracic and lumbar spine with a transpedicular system, and ventral spondylodesis with an autograft. This extensive intervention was justified by the peculiarities in the vertebral body damage and the post-traumatic segmental kyphotic deformity that resulted from delayed medical treatment. An anterior approach was chosen to achieve immobilization at the site of the damage before correction using the transpedicular system. Surgical correction of long-term spinal injuries in children, with the use of a combined approach, is usually laborious and traumatic. The prevention of rigid post-traumatic spine deformities with the help of timely diagnostics and appropriate treatment, including surgery, should be a priority to prevent such cases.

    Personalized medicine relies in part upon comprehensive data on patient treatment and outcomes, both for analysis leading to improved models that provide the basis for enhanced treatment, and for direct use in clinical decision-making. A data warehouse is an information technology for combining and standardizing multiple databases. Data warehousing of clinical data is constrained by many legal and ethical considerations, owing to the sensitive nature of the data being stored. We describe an unconstrained clinical data warehousing architecture, some of the legal constraints that have led us to reconsider this architecture, and the legal and technical solutions to these constraints developed for the clinical data warehouse in the personalized medicine project p-medicine. We also propose some changes to the legal constraints that will further enable clinical research.

    Question: What is the process of developing a clinical information tool to be embedded in the electronic health record of a very large and diverse academic medical center? Setting: The development took place at the University of Pittsburgh Health Sciences Library System. Method: The clinical information tool developed is a search box with subject tabs to provide quick access to designated full-text information resources. Each subject tab offers a federated search of a different pool of resources. Search results are organized “on the fly” into meaningful categories using clustering technology and are directly accessible from the results page. Results: After more than a year of discussion and planning, a clinical information tool was embedded in the academic medical center's electronic health record. Conclusion: The library successfully developed a clinical information tool, called Clinical-e, for use at the point of care. Future development will refine the tool and evaluate its impact and effectiveness. PMID:20648256

    Full Text Available The uptake of electronic records and information technology support in intensive care medicine has been slower than many people predicted. One of the engineering challenges to overcome has been the subtle, but important, variation in clinical practice in different units. A relatively recent innovation that addresses this challenge is practitioner-customizable clinical information systems, allowing clinicians wide scope in adjusting their systems to suit their clinical practice. However, these systems present a significant design challenge, not only of added technical complexity, but in providing tools that support clinicians in doing many of the tasks of a software engineer. This paper reviews the use of a commercially available clinical information system that is intended to be practitioner-customizable, and considers the further design and development of tools to support healthcare practitioners doing end-user customization on their own clinical information systems.

    Full Text Available OBJECTIVES: To investigate the clinical manifestation and surgical outcome of spinal osteoblastoma. METHODS: From June 2006 to July 2011, 18 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 11 males and 7 females with an average age of 27.5 years(range, 16-38 years. The tumors were located at C5 in 7, C6 in 6, C7 in 3, C6-T1 1 in 1 and T11 in 1. Based on WBB classification, 16 were 1-3 or 10-12 and 2 were 4-9 and 1-3. 18 operations had been performed with en bloc resection. A posterior approach was used for 16 patients, and a combined posterior and anterior approach was used for 2 patients. Reconstruction using instrumentation and fusion was performed using spinal instrumentation in 13 patients. We used visual analogue scales (VAS to evaluate the change of pain before and after the operation, and the McCormick System to assess functional status of the spine. Imaging test was used to review the stability and recurrence rate of spine cord, and the confluence of graft bones. RESULTS: All cases were followed up for 24-80 months (average, 38.4 months. The average surgical time was 120.8 minutes (range, 80-220 minutes, with the average intraoperative blood loss of 520 ml (range, 300-1200 ml. During the follow-up period, the VAS grade reduced from 6.46±1.32 to 2.26±1.05 (P <0.05. 15 patients had neurological function improved and 3 remained no change which was evaluated by McCormick scale for spinal function status at final follow-up. CONCLUSIONS: Spinal osteoblastoma has its own specific radiographic features. There is some recurrence in simple curettage of tumor lesion. The thoroughly en bloc resection of tumor or spondylectomy, bone fusion and strong in Ter fixation are the key points for successful surgical treatment.

    Previous research regarding dental students has found modest predictive value in preclinical didactic course grades in predicting clinical performance, but systematic assessment of students' feedback on their perceived preparedness has received little attention as a preclinical assessment methodology. The aim of this study was to assess the perceptions of the dental students at one U.S. academic dental institution regarding their preparedness for clinical performance following the preclinical fixed prosthodontics course. Third- and fourth-year dental students participated in a survey about their perceived preparedness to diagnose and treat patients with fixed prosthodontics needs in the school's dental clinics. The respondents (79 out of 161 students, for a response rate of 49%) rated each item on a five-point Likert scale. Responses about which preclinical procedures of the course prepared students the least and the best were consistent for the third- and fourth-year students. Less than 60% of all responding students felt prepared for planning complex cases and performing laboratory-related procedures. The findings of this study indicate that improvement is required in teaching students about laboratory procedures and problem-solving to adequately prepare them for clinical treatment of patients with fixed prosthodontics needs.

    Full Text Available BACKGROUND: The ability to apply standard and interoperable solutions for implementing and managing medical registries as well as aggregate, reproduce, and access data sets from legacy formats and platforms to advanced standard formats and operating systems are crucial for both clinical healthcare and biomedical research settings. PURPOSE: Our study describes a reproducible, highly scalable, standard framework for a device registry implementation addressing both local data quality components and global linking problems. METHODS AND RESULTS: We developed a device registry framework involving the following steps: (1 Data standards definition and representation of the research workflow, (2 Development of electronic case report forms using REDCap (Research Electronic Data Capture, (3 Data collection according to the clinical research workflow and, (4 Data augmentation by enriching the registry database with local electronic health records, governmental database and linked open data collections, (5 Data quality control and (6 Data dissemination through the registry Web site. Our registry adopted all applicable standardized data elements proposed by American College Cardiology / American Heart Association Clinical Data Standards, as well as variables derived from cardiac devices randomized trials and Clinical Data Interchange Standards Consortium. Local interoperability was performed between REDCap and data derived from Electronic Health Record system. The original data set was also augmented by incorporating the reimbursed values paid by the Brazilian government during a hospitalization for pacemaker implantation. By linking our registry to the open data collection repository Linked Clinical Trials (LinkedCT we found 130 clinical trials which are potentially correlated with our pacemaker registry. CONCLUSION: This study demonstrates how standard and reproducible solutions can be applied in the implementation of medical registries to constitute a re

    Introduction Although anaplastic thyroid carcinoma (ATC) is rare, it is one of the most aggressive human cancers. The optimal multimodal therapy policy of ATC is still debated, and a standardized treatment strategy remains to be established. This study aimed to evaluate the management aspect and prognosis of ATC. Materials and Methods The data were analyzed retrospectively for 50 patients with ATC to evaluate the clinical characters, management and factors influencing survival. Survival analysis was performed by Kaplan-Merier method and log-rank test, and multivariate analysis was performed using Cox proportional hazard model. Results The 1-year and 2-year overall survival rates (OS) were 48.0% and 26.0% respectively in all patients, with the 2-year OS of 40.0% and 31.0% and 6.3% for stage IVA, IVB and IVC respectively (P <0.05). In stage IVA and IVB patients, combined surgery with radiotherapy improved overall survival, and the 2-year OS were 50.0% and 35.7% respectively in the group with combined surgery with radiotherapy and the group with surgery with only (P <0.05). Postoperative radiotherapy improved local control rate in stage IVA and IVB patients (P <0.05). However, surgery, radiotherapy or chemotherapy could not improve the survival of stage IVC patients. Multivariate analysis showed that distant metastases, surgery, radiotherapy and tumor residue could predict the prognosis. Conclusion Combined surgery and radiotherapy could improve overall survival in stage IVA and IVB patients. Patients with ATC have a bad prognosis. Distant metastases, surgery, radiotherapy and tumor residue are the most important factors affecting the prognosis. PMID:27760217

  10. A clinical study on ten cases of superior mesenteric arterial occulusion

    International Nuclear Information System (INIS)

    A total of 10 cases of acute superior mesenteric arterial occulusion (SMAO) treated in our department in a previous 11-year period were divided into the survival (n=4) and death (n=6) groups and studied for the diagnosis, treatment, and postoperative management. An averaged age of them was as high as 81 years. All the patients had some cardiovascular disorders as underlying diseases, and seven patients of them had atrial fibrillation. The time from the onset of SMAO to the treatment ranged from 4 to 96 hours, in that no significant difference was noted between the survival and death groups. Contrast enhanced abdominal CT was conducted preoperatively in all the patients. It was retrospectively considered that preoperative diagnosis had to be made by the CT scans in eight of them who had developed occulusion at the center of the superior mesenteric artery. Except one patient who could be treated by interventional radiology (IVR) using a balloon-tip catheter, the remaining nine patients underwent laparotomy and six out of the nine patients underwent the resection of massive intestines. Seven patients overcame postoperative acute phase, however, only four of them were able to recover their social activities. In order to improve the prognosis of the disease, we are required not only to avoid massive intestinal resection by making early diagnosis, but also to conduct long-term postoperative intensive therapies including those for underlying diseases as well as prevention of recurrence and nutritional management.

  11. Clinical study of 28 cases of cervical lymph node metastasis from an unknown primary carcinoma

    International Nuclear Information System (INIS)

    From 1989 to 2005, 28 patients-20 men and 8 women-with cervical lymph node metastasis from an unknown primary carcinoma were treated and studied retrospectively. In histological diagnosis, open biopsy was conducted in 11 patients and non-open biopsy (fine needle aspiration (FNA) or frozen section diagnosis during surgery) in 17. Blind biopsy under general anesthesia was conducted in 10 patients, showing one primary tumor in the nasopharynx. Tonsillectomy for diagnosis was not done. In region of maximum-size lymph node metastasis, the upper cervical region accounted for 22 cases (79%). The N stage of cervical lymph nodes was as follows: N2a in 4, N2b in 14, N2c in 3, and N3 in 7. The histopathological diagnosis of cervical lymph node was as follows: squamous cell carcinoma in 21, adenocarcinoma in 3, mucoepidermoid carcinoma in 2, and others in 2. Therapy was as follows: only neck dissection in 7, neck dissection with postoperative radiation therapy in 13, and irradiation and chemotherapy in 8. All patients treated with irradiation and chemotherapy had been judged to be inoperable. Seven patients were found to have a subsequent primary tumor. Primary tumor sites were as follows: tonsils in 3 and upper gingiva, base of tongue, lung, and nasopharynx in 1 each. Fluorodeoxyglucose-positron emission tomography (FDG-PET) was conducted in 7 patients but revealed no primary tumor. Overall 5-year survival in this study was 46%. We should pay particular attention to the tonsils for detecting primary tumors in patients with cervical metastasis from an unknown primary carcinoma. (author)

    Full Text Available Background: Primary cutaneous lymphomas (PCLs represent a heterogeneous group of T- and B-cell lymphomas that present in the skin with no evidence of extracutaneous disease at the time of diagnosis. The aim of this study was to assess and report the epidemiological characteristics of PCLs in Isfahan, Isfahan Province, Iran - as a main province of Iran. Materials and Methods: A total of 99 patients were recruited over a recent 10-year period (2003-2013 with diagnosis of PCLs; the patients were classified according to the The World Health Organization/European Organization for Research and Treatment of Cancer (WHO-EORTC criteria. Mean and standard deviations (SDs were used to describe continuous data, numbers, and percentages for categorical data. Statistical significance was defined as P < 0.05. Results: The patients comprised 45 men and 54 women aged 5-80 years (median 36 at diagnosis. The male-to-female ratio was 1:1.2. Histological examination showed features of primary cutaneous B-cell lymphomas (PCBCLs in four cases. The mean ± SD age in primary cutaneous T-cell lymphomas (PCTCLs and PCBCLs was 37.9 ± 16.5 years and 39.7 ± 9.1 years, respectively (P = 0.72. The mean ± SD latent period between the time of diagnosis and initiation of skin lesions in men and women was 2.3 ± 4.1 years and 5.9 ± 10.1 years, respectively (P = 0.02. The most frequent subtypes were mycosis fungoides (MFs (86.9% followed by Sιzary syndrome (SS (4%. Five patients died from PCL-related deaths. Conclusion: The distinguishing epidemiologic characteristics of PCL in Iran are the absence of a male predominance and a lower age of diagnosis. The study highlights the ethnic or regional variations in the clinicoepidemiological characteristics of PCLs.

    Self-neglect is a worldwide and serious public health issue that can have serious adverse outcomes and is more common in older people. Cases can vary in presentation, but typically present as poor self-care, poor care of the environment and service refusal. Community nurses frequently encounter self-neglect cases and health and social care professionals play a key role in the identification, management and prevention of self-neglect. Self-neglect cases can give rise to ethical, personal and professional challenges. The aim of this article is to create a greater understanding of the concept of self-neglect among community nurses.

    2015-12-01

    Full Text Available The US outbreak of B.anthracis infection in 2001 and subsequent cases in the US and Europe demonstrate that anthrax is a continuing risk for the developed world. While several bacterial components contribute to the pathogenesis of B. anthracis, production of lethal toxin (LT is strongly associated with the development of hypotension and lethality. However, the mechanisms underlying the cardiovascular instability LT produces are unclear. Some evidence suggests that LT causes shock by impairing the peripheral vasculature, effects consistent with the substantial extravasation of fluid in patients dying with B. anthracis. Other data suggests that LT directly depresses myocardial function. However a clinical correlate for this latter possibility is less evident since functional studies and post-mortem examination in patients demonstrate absent or minimal cardiac changes. The purposes of this review were to first present clinical studies of cardiac functional and histologic pathology with B. anthracis infection and to then examine in vivo, in vitro, and ex vivo preclinical studies of LT’s myocardial effects. Together, these data suggest that it is unclear whether that LT directly depresses cardiac function. This question is important for the clinical management and development of new therapies for anthrax and efforts should continue to be made to answer it.

  15. Photodynamic therapy with the phthalocyanine photosensitizer Pc 4: The case experience with preclinical mechanistic and early clinical-translational studies

    International Nuclear Information System (INIS)

    Photodynamic therapy (PDT) is emerging as a promising non-invasive treatment for cancers. PDT involves either local or systemic administration of a photosensitizing drug, which preferentially localizes within the tumor, followed by illumination of the involved organ with light, usually from a laser source. Here, we provide a selective overview of our experience with PDT at Case Western Reserve University, specifically with the silicon phthalocyanine photosensitizer Pc 4. We first review our in vitro studies evaluating the mechanism of cell killing by Pc 4-PDT. Then we briefly describe our clinical experience in a Phase I trial of Pc 4-PDT and our preliminary translational studies evaluating the mechanisms behind tumor responses. Preclinical work identified (a) cardiolipin and the anti-apoptotic proteins Bcl-2 and Bcl-xL as targets of Pc 4-PDT, (b) the intrinsic pathway of apoptosis, with the key participation of caspase-3, as a central response of many human cancer cells to Pc 4-PDT, (c) signaling pathways that could modify apoptosis, and (d) a formulation by which Pc 4 could be applied topically to human skin and penetrate at least through the basal layer of the epidermis. Clinical-translational studies enabled us to develop an immunohistochemical assay for caspase-3 activation, using biopsies from patients treated with topical Pc 4 in a Phase I PDT trial for cutaneous T-cell lymphoma. Results suggest that this assay may be used as an early biomarker of clinical response

  1. Brain CT scans and clinical study in very-low-birth-weight infants, including eight cases of cerebellar porencephaly

    International Nuclear Information System (INIS)

    Fifty-nine brain CT scans taken in very-low-birth-weight infants ( < 1500 g) during the past three years were studied retrospectively. Eighty-nine cases of very-low-birth-weight infants were admitted to our premature nursery during the period from Jan. 1, 1982 to Dec. 31, 1984. We obtained brain CT scans in 59 of them, and studied them retrospectively. a) Normal CT in 25 cases, b) enlargement of the extracerebral space in 17, c) megacisterna magna in four, d) unilateral ventriculomegaly in six, e) hydrocephalus in seven, f) cerebral porencephaly in two, g) brain stem atrophy in seven, and h) low density area in the posterior fossa in eight, were observed. The clinical courses of patients a) to f) above were almost similar to those previously reported. g) brain stem atrophy was found on CT scans in seven cases. Five of them developed infantile spasms later. This suggests that one of the main sites of lesions in infantile spasms is the tegmentum of the brain stem. h) Low density area in the posterior fossa was found on CT in eight cases. Three of them showed cerebellar defective lesions on metrizamide CT or RI cisternography. Four of them showed no defective lesion in the posterior fossa on ultrasonography at the early neonatal stage. These lesions in the posterior fossa are believed to be cerebellar porencephaly, which occurred after birth. Seven cases of cerebellar porencephaly, except for one with SFD, had respiratory and cardiovascular diseases, such as neonatal asphyxia, RDS, PDA, and/or apnea. The cerebral lesions such as intracranial hemorrhage, hydrocephalus and cerebral porencephaly, which had been observed in all cases of cerebellar porencephaly, finally resulted in cerebral palsy, mental retardation and infantile spasms.

    Both critics and supporters of evidence-based medicine view clinical practice guidelines as an important component of this self-defined "new paradigm" whose goal is to rationalize medicine by grounding clinical decision-making in a careful assessment of the medical literature. We present an analysis of the debates within a guideline development group (GDG) that led to the drafting, revision and publication of a French cancer guideline. Our ethnographic approach focuses on the various aspects of the dispositif (or apparatus) that defines the nature and roles of participants, procedures, topics and resources within the GDG. Debates between GDG members are framed (but not dictated) by procedural and methodological rules as well as by the reflexive critical contributions of the GDG members themselves, who justify their (tentative) recommendations by relating to its (possible or intended) audiences. Guideline production work cannot be reduced to an exchange of arguments and to consensus-seeking between pre-defined professional interests. It is about the production of a text in the material sense of the term, i.e. as a set of sentences, paragraphs, statements and formulations that GDG members constantly readjust and rearrange until closure is achieved. As such, guidelines partake in the emergence and stabilization of a new configuration of biomedical knowledge and practices grounded in the establishment of mutually constitutive links between two processes: on the one hand, the re-formatting of clinical trials into a device for producing carefully monitored evidence statements targeting specific populations and clinical indications and, on the other hand, the increasingly pervasive role of regulatory processes.

    Notalgia paresthetica (NP) is a common but often unrecognized neurocutaneous condition, with very few cases reported to date. It is characterized by pruritus localized in an area between D2 and D6 dermatomes, sometimes accompanied by sensory neuropathies and/or electrical conductivity disorders. Cutaneous pigmented patches and friction amyloidosis can arise with irritation. Some hereditary cases have been noted mainly in young patients, associated with multiple endocrine neoplasia type 2A. However, NP mainly occurs in older patients and most are sporadic pathologies linked with musculoskeletal compression of spinal nerves. Only capsaicin has shown some (but unfortunately only transient) efficacy in relieving NP symptoms. We present observations on 12 sporadic cases of NP. Spinal X-rays revealed dorsal arthrosis or spinal static disequilibrium in nine of these patients. Six patients underwent spinal and paraspinal ultrasound or radiation (better) physiotherapy, and the symptoms subsided in four of these cases. These results highlighted that spinal disorders could be a determining factor in NP, indicating that patients could benefit from physiotherapy. PMID:10461640

    Our experience with germ cell tumours of the ovary is reviewed. Over the last 10 years, 15 cases, representing 6,4% of all our referred patients with malignant ovarian tumours, have been analysed. The type of tumour, histological appearances, stage, treatment and results of treatment are presented. The tumour most commonly seen was the dysgerminoma, comprising 60% of all cases (9 patients). Multimodal treatment generally consisted of surgery and radiotherapy for dysgerminoma with the addition of chemotherapy for the non-dysgerminomas. Survival depends on the stage and histological appearances of the tumour. Patients in whom the disease is at advanced stages have a poor prognosis, irrespective of histological features. A general review of this subject is also given.

Mean ASSIST score was significantly higher among the cases compared with the control, p < 0.001. Respondents of male gender and those who were not married were significantly more likely to be cannabis users among patients with schizophrenia, p < 0.001, p < 0.02 respectively. Conclusion: Cannabis use was prevalent among patients with schizophrenia and was associated with health risks. Thus, routine screening for cannabis use and brief intervention is suggested to be integrated into care for adolescents and adults with schizophrenia.

    [Purpose] The purpose of this study was to determine the effects of Adeli suit therapy (AST) on gross motor function and gait function in children with cerebral palsy. [Subjects and Methods] Two participants with spastic cerebral palsy were recruited to undergo AST. AST was applied in 60-minute sessions, five times per week, with 20 sessions total over 4 weeks. Assessments of gross motor function, spatiotemporal parameters, and functional ambulation performance for gait were conducted. [Results] Gross motor function, cadence, and functional ambulation performance improved after the intervention in both cases. [Conclusion] Although additional follow-up studies are required, the results demonstrated improved gross motor function and functional ambulation performance in the children with cerebral palsy. These findings suggest a variety of applications for conservative therapeutic methods that require future clinical trials in children with cerebral palsy. PMID:27390453

    Full Text Available Introduction: Diabetic foot is a complication of Diabetes Mellitus, which is a group of metabolic disorders sharing the phenotype of hyperglycemia. The aim of the therapy is to avoid diabetic foot complications, salvage the limb with available modalities in hospital, preventing recurrences and rehabilitation. Methods: This article summarizes the profile of 200 patients with diabetic foot seen in General Surgery department of Civil Hospital at Ahmedabad. The diagnosis of diabetic foot was based on clinical, biochemical and radiological investigations. Clinical presentation can be divided into infective, vascular and neuropathic groups. Results: Average age of presentation was 55.02 year. There is a higher incidence in male patients, majority of patients (57% belongs to lower socioeconomic status. The average duration of diabetes is 9.78 years. Severity of lesion correlated with severity and duration of diabetes. Commonest presenting feature is an abscess followed by gangrene. Staph.aureus is the most common organism isolated from diabetic foot. X-Rays of feet were taken and majority presented with osteomyelitic changes. The average duration of hospital stay was 17.34 days. Conclusion: Foot ulceration in diabetic patients is a resource consuming, disabling morbidity that often is the first step towards lower extremity amputation. Prevention is the best treatment. Effective glycemic control and education are of key importance for decreasing diabetic foot disease, while early presentation and hospital admission, aggressive and appropriate medical and surgical treatment according to grade if disease can improve outcome and reduce the morbidity and mortality due to diabetes.

    A total of 33 patients with advanced head and neck cancer (AHNC) treated with sequential chemoradiotherapy (SCRT) were retrospectively evaluated at Gunma University Hospital between 2009 and 2011. The regimen of SCRT was docetaxel, cisplatin, and fluorouracil (TPF)-based induction chemotherapy (ICT), accompanied by docetaxel and cisplatin-based concurrent chemoradiotherapy (CCRT), and oral administration of TS-1 after that. The response rate was 61%, the 3-year overall survival rate was 42%, the non-tumor-bearing survival rate was 27%, and the tumor-bearing survival rate was 15%. Fourteen of 33 patients were tumor-free, and their 3-year overall survival rate was surprisingly 86%. On the other hand, 3-year overall survival rate in the remaining 19 patients was significantly low. To select good response cases for ICT was important. In such cases, TPF should be applied repeatedly, which achieved a 61% response rate even in AHNC. A long-term TS-1 oral medication suppressed cancer regrowth and contributed to long-term survival.

    2010-05-01

    Learning how to 'think like doctors' can be difficult for undergraduate medical students in their early clinical years. Our model of collaborative Integrated Case Learning (ICL) and simulated clinical reasoning aims to address these issues. Taking a socio-cultural perspective, this study investigates the reflective learning interactions and practices of clinical thinking that emerged in the ICL environment. We also explore how third year medical students perceived their ICL experiences in relation to the clinical situations encountered in the hospital setting. The context for the inquiry is a rural Clinical School in North West Victoria, Australia. We used a qualitative case study methodology following eight third-year medical students over an academic year. Individual and group interviews were conducted, together with observations and document/artefact analysis. Data was analysed using content and narrative methods. The ICL program was well received. Findings suggest that the group-based, simulated clinical reasoning process appears to help undergraduate medical students to rehearse, articulate and question their clinical decision-making pathways. We argue that the ICL process offers a professionally challenging, but supportive group learning 'space' for students to practise what it might mean to 'think', 'talk' and 'perform' like doctors in real settings. The ICL environment also appears to create a connective bridge between the 'classroom' and clinical practice.

    AIM: To evaluate different types of treatment for sigmoid volvulus and clarify the role of endoscopic intervention versus surgery.METHODS: A retrospective review of the clinical presentation and imaging characteristics of 33 sigmoid volvulus patients was presented, as well as their diagnosis and treatment, in combination with a literature review.RESULTS: In 26 patients endoscopic detorsion was achieved after the first attempt and one patient died because of uncontrollable sepsis despite prompt operative treatment. Seven patients had unsuccessful endoscopic derotation and were operated on. On two patients with gangrenous sigmoid, Hartmann's procedure was performed. In five patients with viable colon, a sigmoid resection and primary anastomosis was carried out. Three patients had a lavage "on table" prior to anastomosis, while in the remaining 2 patients a diverting stoma was performed according to the procedure of the first author. Ten patients were operated on during their first hospital stay (3 to 8 d after the deflation). All patients had viable colon; 7 patients had a sigmoid resection and primary anastomosis, 2 patients had sigmoidopexy and one patient underwent a near-total colectomy. Two patients (sigmoidectomy-sigmoidopexy) had recurrences of volvulus 43 and 28 mo after the initial surgery. Among 15 patients who were discharged from the hospital after non-operative deflation, 3 patients were lost to follow-up. Of the remaining 12 patients, 5 had a recurrence of volvulus at a time in between 23 d and 14 mo. All the five patients had been operated on and in four a gangrenous sigmoid was found. Three patients died during the 30 d postoperative course. The remaining seven patients were admitted to our department for elective surgery. In these patients, 2 subtotal colectomies, 3 sigmoid resections and 2 sigmoidopexies were carried out. One patient with subtotal colectomy died. Taken together of the results, it is evident that after 17 elective operations we had

    Full Text Available Abstract Background Environmental pollution is a known risk factor for multiple diseases and furthermore increases rate of hospitalisations. We investigated the correlation between emergency room admissions (ERAs of the general population for respiratory diseases and the environmental pollutant levels in Milan, a metropolis in northern Italy. Methods We collected data from 45770 ERAs for respiratory diseases. A time-stratified case-crossover design was used to investigate the association between air pollution levels and ERAs for acute respiratory conditions. The effects of air pollutants were investigated at lag 0 to lag 5, lag 0–2 and lag 3–5 in both single and multi-pollutant models, adjusted for daily weather variables. Results An increase in ozone (O3 levels at lag 3–5 was associated with a 78% increase in the number of ERAs for asthma, especially during the warm season. Exposure to carbon monoxide (CO proved to be a risk factor for pneumonia at lag 0–2 and in the warm season increased the risk of ERA by 66%. A significant association was found between ERAs for COPD exacerbation and levels of sulphur dioxide (SO2, CO, nitrate dioxide (NO2, and particulate matter (PM10 and PM2.5. The multipollutant model that includes all pollutants showed a significant association between CO (26% and ERA for upper respiratory tract diseases at lag 0–2. For chronic obstructive pulmonary disease (COPD exacerbations, only CO (OR 1.19 showed a significant association. Conclusions Exposure to environmental pollution, even at typical low levels, can increase the risk of ERA for acute respiratory diseases and exacerbation of obstructive lung diseases in the general population.

    The aim of the study was to investigate the clinical features of systemic lupus erythematous (SLE) complicated with Evans syndrome (ES). We conducted a retrospective case-control study to compare the clinical and laboratory features of age- and gender-matched lupus patients with and without ES in 1:3 ratios. In 5724 hospitalized SLE patients, we identified 27 (0.47%, 22 women and 5 men, average age 34.2 years) SLE patients complicated with ES. Fifteen patients (55.6%) presented with hematologic abnormalities initially, including 6 (22.2%) cases of isolated ITP, 4 (14.8%) cases of isolated AIHA, and 5 (18.5%) cases of classical ES. The median intervals between hematological presentations the diagnosis of SLE was 36 months (range 0-252). ES developed after the SLE diagnosis in 4 patients (14.8%), and concomitantly with SLE diagnosis in 8 patients (29.6%). Systemic involvements are frequently observed in SLE patients with ES, including fever (55.6%), serositis (51.9%), hair loss (40.7%), lupus nephritis (37%), Raynaud phenomenon (33.3%), neuropsychiatric (33.3%) and pulmonary involvement (25.9%), and photosensitivity (25.9%). The incidence of photosensitivity, hypocomplementemia, elevated serum IgG level, and lupus nephritis in patients with ES or without ES was 25.9% vs 6.2% (P = 0.007), 88.9% vs 67.1% (P = 0.029), 48.1% vs 24.4% (P = 0.021), and 37% vs 64.2% (P = 0.013), respectively. Twenty-five (92.6%) patients achieved improvement following treatment of glucocorticoids and immunosuppressants as well as splenectomy, whereas 6 patients experienced the relapse and 1 patient died from renal failure during the follow-up. ES is a relatively rare complication of SLE. Photosensitivity, hypocomplementemia, and elevated serum IgG level were frequently observed in ES patients, but lupus nephritis was less observed. More than half of patients presented with hematological manifestation at onset, and progress to typical lupus over months to years. Therefore

    1988-11-01

    Twenty-two patients with selective hypoaldosteronism (SH) were studied. In 18 of them decreased levels of plasma renin activity (PRA) were associated with the syndrome: 12 patients showed the idiopathic form of SH, while in 6, the syndrome was attributable to the administration of non-steroid anti-inflammatory drugs. In the remaining 4 patients, the hypoaldosteronism was characterized by associated increased PRA levels but functional studies excluded a diagnosis of adrenocortical insufficiency. From a critical review of the literature and from the present observations it seems likely that SH is a syndrome with a heterogeneous pathogenesis. The possibility exists that the major alterations in potassium homeostasis that characterize the syndrome of SH, though mainly attributable to deficiency of aldosterone secretion may actually depend on the concurrence of underlying mechanisms, in particular on the presence of distal nephron dysfunctions.

    2014-04-01

    Full Text Available Accurate assessment of obsessions and compulsions is a crucial step in treatment planning for Obsessive-Compulsive Disorder (OCD. In this pilot study, we sought to determine if the use of Ecological Momentary Assessment (EMA could provide additional symptom information beyond that captured during standard assessment of OCD. We studied three adults diagnosed with OCD and compared the number and types of obsessions and compulsions captured using the Yale-Brown Obsessive-compulsive Scale (Y-BOCS compared to EMA. Following completion of the Y-BOCS interview, participants then recorded their OCD symptoms into a digital voice recorder across a twelve-hour period in reply to randomly sent mobile phone SMS prompts. The EMA approach yielded a lower number of symptoms of obsessions and compulsions than the Y-BOCS but produced additional types of obsessions and compulsions not identified by the Y-BOCS. We conclude that the EMA-OCD procedure may represent a worthy addition to the suite of assessment tools used when working with clients who have OCD. Further research with larger samples is required to strengthen this conclusion.

    PURPOSE: To describe cases of postoperative endophthalmitis in the European Society of Cataract & Refractive Surgeons (ESCRS) study of the prophylaxis of endophthalmitis, compare characteristics of unproven cases and cases proven by culture or polymerase chain reaction, and compare the characteristics with those in other reported series. SETTING: Twenty-four ophthalmology units in Austria, Belgium, Germany, Italy, Poland, Portugal, Spain, Turkey, and the United Kingdom. METHODS: Univariable and multivariable logistic regression models were used to analyze data for statistical association of signs and symptoms in cases with proven or unproven endophthalmitis. Specific data describing characteristics of the cases were compared between the 2 types of cases. RESULTS: Data from 29 endophthalmitis cases were analyzed. Swollen lids and pain were statistically associated with proven cases of endophthalmitis on univariable regression analysis. Multivariable analysis indicated that swollen lids and an opaque vitreous were associated with proven cases. Five cases of endophthalmitis occurred in the cefuroxime-treated groups. No case of streptococcal infection occurred in the cefuroxime-treated groups. However, cases of infection due to streptococci showed striking differences in visual acuity and were associated with earlier onset. Characteristics in the 29 cases parallel results in previous studies, such as the Endophthalmitis Vitrectomy Study, although the addition of a control group in the ESCRS study elicited additional findings. CONCLUSION: Swollen lids, pain, and an opaque vitreous were statistically associated with proven endophthalmitis cases in the ESCRS study.

    International Nuclear Information System (INIS)

    This report summarized the clinical experience of fetal liver transplantation (FLT) in the medical handling of accidental (case 1) or therapeutic (cases 2-4) acute radiation sickness of severe haemopoietic form. In addition to receiving 80 mg/kg of cyclophosphamide, cases 2, 3 and 4 were exposed to total body single irradiation of 5.5, 5.0 and 5.0 Gy, respectively; while case 1 was exposed to whole body irradiation of 5.2 Gy only. The total number of nucleated fetal liver cells transplanted was 2.26-4.1 x 108/kg. Only 2-5% of peripheral blood cells of cases 2, 3 and 4 were found to have allogeneic marker. The author points out that FLT may be beneficial in those cases of accidental irradiation or patients with acute leukemia when there were no HLA-identical bone marrow donors available

    The present article summarizes Metabolites in Safety Testing (MIST) studies on a glucokinase activator, N,N-dimethyl-5-((2-methyl-6-((5-methylpyrazin-2-yl)carbamoyl)benzofuran-4-yl)oxy)pyrimidine-2-carboxamide (PF-04937319), which is under development for the treatment of type 2 diametes mellitus. Metabolic profiling in rat, dog, and human hepatocytes revealed that PF-04937319 is metabolized via oxidative (major) and hydrolytic pathways (minor). N-Demethylation to metabolite M1 [N-methyl-5-((2-methyl-6-((5-methylpyrazin-2-yl)carbamoyl)benzofuran-4-yl)oxy)pyrimidine-2-carboxamide] was the major metabolic fate of PF-04937319 in human (but not rat or dog) hepatocytes, and was catalyzed by CYP3A and CYP2C isoforms. Qualitative examination of circulating metabolites in humans at the 100- and 300-mg doses from a 14-day multiple dose study revealed unchanged parent drug and M1 as principal components. Because M1 accounted for 65% of the drug-related material at steady state, an authentic standard was synthesized and used for comparison of steady-state exposures in humans and the 3-month safety studies in rats and dogs at the no-observed-adverse-effect level. Although circulating levels of M1 were very low in beagle dogs and female rats, adequate coverage was obtained in terms of total maximal plasma concentration (∼7.7× and 1.8×) and area under the plasma concentration-time curve (AUC; 3.6× and 0.8× AUC) relative to the 100- and 300-mg doses, respectively, in male rats. Examination of primary pharmacology revealed M1 was less potent as a glucokinase activator than the parent drug (compound PF-04937319: EC50 = 0.17 μM; M1: EC50 = 4.69 μM). Furthermore, M1 did not inhibit major human P450 enzymes (IC50 > 30 μM), and was negative in the Salmonella Ames assay, with minimal off-target pharmacology, based on CEREP broad ligand profiling. Insights gained from this analysis should lead to a more efficient and focused development plan for fulfilling MIST requirements with

The present study explores the development of both components of autobiographical memory in an 8-year-old boy diagnosed with Asperger’s syndrome, based on three examinations in 2007, 2008 and 2010. On each occasion, he underwent a general neuropsychological assessment including theory of mind tasks, and a specially-designed autobiographical memory task allowing us to test both the semantic and the episodic components for three lifetime periods (current year, previous year and earlier years. We observed difficulties in strategic retrieval and theory of mind, with a significant improvement between the second and third examinations. Regarding autobiographical memory, different patterns of performance were noted in all three examinations: 1 relative preservation of current-year personal knowledge, but impairment for the previous and earlier years, and 2 impairment of episodic memory for the current and previous year, but performances similar to those of controls for the earlier years. The first pattern can be explained by abnormal forgetting and by the semanticization mechanism, which needs verbal communication and social interaction to be efficient. The second pattern suggests that the development of episodic memory only reached the stage of event memory. This term refers to memory for personal events lacking in details or spatiotemporal specificity, and is usually observed in children younger than 5. We conclude that the abnormal functioning of social cognition in ASD, encompassing social and personal points of view, has an impact on both components of

  14. Relationship Between Blood Fibrinogen Concentration and Pathological Features of Cancer Patients: A 139-case Clinical Study

    Full Text Available Angiogenesis and coagulation are among the most consistent host responses to the presence of a malignant tissue. Pathological angiogenesis and coagulation are often occurred in patients with solid tumors, especially in the occurrence of neoplasm metastasis and as targets for anti-metastatic drugs such as antiangiogenesis agents, coagulation-mediated agents and anticancer drugs. Since fibrinogen (Fib is the most abundant and key haemostatic protein taking part in angiogenesis and coagulation, its biological and pathophysiological roles in cancer patients are intriguing. To continue foundational and translational research on Fib-related cancer pathogenesis, a phase II survey of 139 patients was carried out at the Central Hospital of Jing-An district and Shanghai University, Shanghai, China. The mean BFC of the cancer patients in this survey was overall about 35-50% greater than that in the normal population. This study showed that the mean BFC was higher in patients with long-distance metastases (N1M1 patients than in patients with no sign of long-distance metastases (N0M0 patients. Mean BFCs were 4.42 g/L (n= 21 in patients with lung cancer, 4.36 g/L, and in patients with hepatic cancer (n=5, and 4.63 g/L in patients with stomach cancer (n=8, all higher than the average value of the cancer patients overall (4.16 g/L. However, patients with bowel and colon cancers 3.79 g/L (n=16 showed lower than them. BFC levels increased with increasing cancer duration (latency > 1 year. There was a slight decrease in BFC after one or two treatment cycles, but a more marked decrease after surgery. We propose that the BFC level in cancer patients may be influenced by and related to many aspects of cancer progression such as metastatic conditions, tumor origins, patient’s pathological stage and disease latency. As an important first-hand pathologic-therapeutics relationship study, it provides evidence for the potentiality of a new approach of Fib-targeted as

    The purpose of this three-year, prospective, follow-up study was to evaluate whether aggressive gap arthroplasty is essential in the management of ankylosis of the temporomandibular joint (TMJ). Fifteen patients were treated by the creation of a minimal gap of 5-8mm and insertion of an interpositional gap arthroplasty using the temporalis fascia. Eleven patients had unilateral coronoidectomy and 4 bilateral coronoidectomy based on Kaban's protocol. Preoperative assessment included recording of history, clinical and radiological examinations, personal variables, the aetiology of the ankylosis, the side affected, and any other relevant findings. Patients were assessed postoperatively by a surgeon unaware of the treatment given for a minimum of 3 years, which included measurement of the maximal incisal opening, presence of facial nerve paralysis, recurrence, and any other relevant findings. Of the 15 patients (17 joints), 12 had unilateral and three had bilateral involvement, with trauma being the most common cause. The patients were aged between 7 and 29 years (mean (SD) age 20 (8) years). Preoperative maximal incisal opening was 0-2mm in 8 cases and 2-9mm in 9. Postoperatively adequate mouth opening of 30-40mm was achieved in all cases, with no recurrence or relevant malocclusion during 3-year follow up. However, patients will be followed up for 10 years. Aggressive gap arthroplasty is not essential in the management of ankylosis of the TMJ. Minimal gap interpositional arthroplasty with complete removal of the mediolateral ankylotic mass is a feasible and effective method of preventing recurrence. PMID:23219020

    2009-01-01

    Full Text Available Background: Various studies worldwide suggest that human leukocyte antigen (HLA region may be involved in the genetic susceptibility of vitiligo but little information is available from India. Aim: To find the HLA associated susceptibility to develop vitiligo in Indian patients and to detect role of HLA in familial vitiligo. Methods: This was a case controlled study which included all patients suffering from vitiligo over a period of one and half years. Clinical details were noted and sera collected from these patients were screened for the presence of HLA class I antibodies. The clinical features and HLA antigens were assessed and comparison was made between patients with familial and nonfamilial vitiligo. Results: Out of 114 patients studied, 84 had family history and 30 had no family history. Patients with family history of vitiligo have higher chances of acquiring vitiligo if first degree relatives are affected compared to if second degree relatives are affected. Family history of vitiligo is associated with an early onset of vitiligo (< 20 years. There was no statistically significant difference in the type, stability, and severity of vitiligo in both the groups. HLA results in both the groups revealed increase in HLA A2, A11, A31, A33, B17, B35, B40, and B44 alleles while HLA A9, B13, and B53 alleles were decreased. Family history was associated with HLA A2, A28, A31, and B44 alleles. Early onset of vitiligo (< 20 years was significantly associated with HLA A2, A11, B17, B35, and B44 alleles. The patients with severe affection (> 10% area showed in significant association with HLA A10 and B8. Conclusion: Family history of vitiligo is associated with an early onset of vitiligo. There is no correlation of family history with the type of vitiligo, stability of lesions, and areas involved. Severity is not associated with family history. Apart from other alleles, alleles A2, and B44 play a significant role in vitiligo in the Indian patients.

  8. Correlation of clinical, radiographic, and surgical localization of intervertebral disc extrusion in small-breed dogs: a prospective study of 50 cases

    International Nuclear Information System (INIS)

    Objective-To compare prospectively clinical, radiographic, and surgical findings of intervertebral disc extrusion (IDE) localization in small-breed dogs and to determine the best means of lesion localization for the purpose of hemilaminectomy. Study Design-Clinical, radiographic, and surgical findings of small-breed dogs with thoracolumbar IDE were prospectively compared for agreement on lesion localization. Sample Population-50 small-breed dogs with IDE treated at the three participating veterinary hospitals were included in the study if no other confounding diseases were identified and if the owner gave permission for diagnostic tests and surgery. Methods-Clinical and surgical findings were recorded by the surgeon assigned to the case. Radiographic studies were evaluated independently by two radiologists blinded as to the clinical and surgical findings. K values and 95% confidence intervals were calculated for agreement on lesion localization by clinical, radiographic, and surgical means and for agreement between radiologists. Results-K values for agreement of lesion localization were as follows: clinical versus surgical, 0.595; radiologist A versus radiologist B, 0.81; radiologist A versus surgical findings, 0.60; radiologist B versus surgical findings, 0.71. Both radiologists interpretation of IDE localization agreed with surgical localization in 60% of cases. Conclusions-Clinical lateralization of IDE was found to be the least reliable factor of those studied for determining on which side the hemilaminectomy should be performed. Results of this study differ from those of previous studies examining the reliability of myelography to localize the site of IDE accurately. The results of this study further suggest that surgery may not be an absolute standard for determination of the localization of IDE in small-breed dogs. Clinical Relevance-Intervertebral disc extrusion in small-breed dogs frequently results in bilateral distribution of extruded material. Computed

    The process of "clinical reasoning" is exemplified as supportive to the complaint management of the Statutory Medical Health Advisory Board in Lower Saxony, Germany, within the operational division for long-term care insurance. A model case from real life illustrates in detail the hypothetical-deductive approach by Beusheusen and Klemme/Siegmann. Because of the potential area of conflicts between human concern in the case of a long-term care burden and legal requirements, the process was analysed in terms of a pragmatic reasoning. Human resources of the claimant and persons in charge at customer's service were demonstrated as well as political, statutory and institutional determining factors. Concluding self-perception validates the process in the context of evidence-based practice. PMID:25397910

    Altmann, Karl-Heinz

    As indicated in previous chapters, epothilone research so far has delivered seven new chemical entities that have been advanced to clinical trials in humans (Fig. 1). However, the amount of clinical data publicly available at this time strongly varies between individual compounds, depending on their development stage, but also on the general publication policy of the developing company. The compound that has been most comprehensively characterized in the clinical literature is ixabepilone (BMS-247550), for which trial results have been described in a number of articles in peer-reviewed journals and which has been granted FDA approval for two clinical indications on Oct. 16, 2007. For all other compounds, most of the information on clinical trials is available only in abstract form. In all these cases it remains uncertain, whether the content of these abstracts fully reflects the content of the subsequent (poster or oral) presentations at the corresponding meeting; in fact, it seems likely that additional data will have been included in the actual meeting presentations that may not have been available at the time of abstract submission. As this is unknown to the author, such additional information cannot be considered in this chapter, which is solely based on information documented in accessible abstracts or journal publications. It should also be kept in mind that the interpretation of data from ongoing clinical trials or forward looking statements based on data from completed trials are always preliminary in character.

  14. Combining gene expression, demographic and clinical data in modeling disease: a case study of bipolar disorder and schizophrenia

    Directory of Open Access Journals (Sweden)

    Dobrin Seth

    2008-11-01

    Full Text Available Abstract Background This paper presents a retrospective statistical study on the newly-released data set by the Stanley Neuropathology Consortium on gene expression in bipolar disorder and schizophrenia. This data set contains gene expression data as well as limited demographic and clinical data for each subject. Previous studies using statistical classification or machine learning algorithms have focused on gene expression data only. The present paper investigates if such techniques can benefit from including demographic and clinical data. Results We compare six classification algorithms: support vector machines (SVMs, nearest shrunken centroids, decision trees, ensemble of voters, naïve Bayes, and nearest neighbor. SVMs outperform the other algorithms. Using expression data only, they yield an area under the ROC curve of 0.92 for bipolar disorder versus control, and 0.91 for schizophrenia versus control. By including demographic and clinical data, classification performance improves to 0.97 and 0.94 respectively. Conclusion This paper demonstrates that SVMs can distinguish bipolar disorder and schizophrenia from normal control at a very high rate. Moreover, it shows that classification performance improves by including demographic and clinical data. We also found that some variables in this data set, such as alcohol and drug use, are strongly associated to the diseases. These variables may affect gene expression and make it more difficult to identify genes that are directly associated to the diseases. Stratification can correct for such variables, but we show that this reduces the power of the statistical methods.

    Full Text Available Background: Distance education methods have taken on greater importance as medical student education has moved off campus into the community. What the best methods are for conveying information to students at distant sites has not been determined. Objective: To determine if students at distant community sites who received an otitis media study case by e-mail that was enhanced with a referral to a web-based otitis study case, performed better on otitis OSCE stations than students who received the same case not enhanced with visuals or referrals to a web-based otitis case. Design/Methods: Students were randomized by community site to receive either the enhanced (E or simple otitis study case (S. Students were e-mailed an otitis media study case during the 5th week of the rotation. Those randomized to the E-case received a case that started with a case scenario followed by a "Task" that instructed them to go to this web address: http://www.aap.org/otitismedia/www/vc/ear/index.cfm (American Academy of Pediatrics Otitis Web Site. They were then to select "Case 1" which was a continuation of the case scenario present on their e-mail. A list of learning objectives was also printed on the e-mail. Students receiving the S-case viewed the same case scenario and objectives, but were not instructed to go to the web page. All students rotated through two OSCE otitis stations. In the first station they interviewed a simulated patient(OSCE-SP and counseled her on the management of her 12 month old with otitis. Within that station they viewed a video of a pneumoscopic exam of two ears, one ear with otitis and the other ear normal. At the 2nd otitis station the student presented the case to a faculty and was asked a series of questions about otitis media(OSCE-PR. Scores on the two stations were compared by group. Results: There were 198 students who took the OSCE. 178 (90% responded to a survey that indicated they had opened and read the e-mailed case. There

    Schmallenberg virus (SBV) was first detected in Switzerland in July 2012 and many Swiss dairy farmers reported acute clinical signs in dairy cattle during the spread of the virus until December 2012. The objectives of the present study were to investigate the effects of an acute infection with SBV on milk yield, fertility and veterinary costs in dairy farms with clinical signs of SBV infection (case farms), and to compare those farms to a matched control group of dairy farms in which cattle did not show clinical signs of SBV infection. Herd size was significantly (pcase farms (33 cows, n=77) than in control farms (25 cows, n=84). Within case herds, 14.8% (median) of the cows showed acute clinical signs. Managers from case farms indicated to have observed a higher abortion rate during the year with SBV (6.5%) than in the previous year (3.7%). Analysis of fertility parameters based on veterinary bills and data from the breeding associations showed no significant differences between case and control farms. The general veterinary costs per cow from July to December 2012 were significantly higher (p=0.02) in case (CHF 19.80; EUR 16.50) than in control farms (CHF 15.90; EUR 13.25). No differences in milk yield were found between groups, but there was a significant decrease in milk production in case farms in the second half year in 2012 compared to the same period in 2011 (pclinical signs (n=461) were treated by a veterinarian. The average calculated loss after SBV infection for a standardized farm was CHF 1606 (EUR 1338), which can be considered as low at the national level, but the losses were subject to great fluctuations between farms, so that individual farms could have very high losses (>CHF 10,000, EUR 8333).

    Full Text Available OBJECTIVE: To investigate the clinical features, outcome, and risk factors of disease flares in patients with pregnancy-related lupus (PRL. METHODS: Medical charts of 155 consecutive PRL inpatients were systematically reviewed, including demographic data, clinical features, laboratory findings, treatment, complications, and outcome. RESULTS: PRL cases were divided into active (a-PRL (n = 82, 53.0% and stable lupus (s-PRL (n = 73, 47.0%. Compared with nonpregnant active female systemic lupus erythematosus (SLE patients, a-PRL including new-onset lupus (n-PRL and flare lupus (f-PRL (n = 41 respectively, had a higher incidence of renal and hematological involvement but less mucocutaneous and musculoskeletal involvement (p<0.05. The incidence of preeclampsia/eclampsia, fetal loss, and preterm birth were significantly higher in a-PRL than in s-PRL (p<0.05. Despite receiving a more vigorous glucocorticoid treatment, a-PRL mothers had a poorer prognosis (p<0.001. Five (6.1% of them died and 13 (15.9% developed severe irreversible organ failure, whereas none of these events was observed in the s-PRL group. Multivariate logistic analysis indicated that a history of lupus flares and serological activity (hypocomplementemia and/or anti-dsDNA positivity at the time of conception were associated with lupus flares in PRL mothers. CONCLUSIONS: SLE patients with a flare history and serological activity at the time of conception were at an increased risk of disease flares during pregnancy and puerperium. a-PRL patients were more prone to renal and hematological involvement, pregnancy complications, and a poorer prognosis despite more vigorous glucocorticoid treatment.

    Full Text Available The purpose of this study was to evaluate the clinical outcomes of osteonecrosis of the femoral head after autologous bone marrow stem cell implantation. We searched the PubMed, Embase and Web of Science databases and included all case-control trials that reported on the clinical outcomes of osteonecrosis progression, incidence of total hip arthroplasty and improvement in Harris hip scores. Overall, seven case-control trials were included. Compared with the controls, patients treated with the bone marrow stem cells implantation treatment showed improved clinical outcomes with delayed osteonecrosis progression (odds ratio = 0.17, 95% CI: 0.09 - 0.32; p<0.001, a lower total hip arthroplasty incidence (odds ratio = 0.30, 95% CI: 0.12 - 0.72; p<0.01 and increased Harris hip scores (mean difference = 4.76, 95% CI: 1.24 - 8.28; p<0.01. The heterogeneity, publication bias, and sensitivity analyses showed no statistical difference significant differences between studies. Thus, our study suggests that autologous bone marrow stem cells implantation has a good therapeutic effect on osteonecrosis of the femoral, resulting in beneficial clinical outcomes. However, trials with larger sample sizes are needed to confirm these findings.

    Full Text Available Neuronal ceroid-lipofuscinosis (NCL is a recent term, proposed for acurate designation of the late-onset types of Amaurotic Family Idiocy (AFI. Histopathology shows ubiquitous intraneuronal accumulation of lipopigments, being the most important factor for characterization of the entity at present time. Biochemical changes and pathogenesis are obscure. NCL is in contrast to the infantile type of AFI (Tay-Sachs disease, in which intraneuronal accumulation of gangliosides (sphingolipids is due to the well known deficiency of a lysosomal enzyme. The authors report on four cases of NCL, two brothers of the late infantile (Jansky-Bielschowsky type and a brother and a sister of the juvenile (Spielmeyer-Sjögren type. One autopsy and three cortical biopsies revealed moderate to severe distention of the neurons by lipopigment, with nerve cell loss, gliosis and cerebral atrophy. Lipopigment was also increased in liver, heart and spleen. The patients were the first in Brazilian literature in whom the storage material was identified as lipopigment by histochemical methods. A brief summary of the clinical features of NCL is presented, and relevant problems are discussed, concerning interpretation of the nature of the storage material, and significance of the disease for gerontological research.

    Background Chronic active Epstein-Barr virus infection (CAEBV) has been previously reported to be sometimes associated with an aggressive clinical course. The characteristics of CAEBV in Mainland Chinese pediatric patients are largely unreported. The main aims of this survey were to recognize the clinical features of CAEBV in children and to explore its diagnostic criteria and risk factors.Methods A retrospective study was performed on 53 pediatric patients (36 boys and 17 girls) with CAEBV who were admitted to Beijing Children's Hospital between 2003 and 2007. All their medical records were reviewed and analyzed. For each patient, demographic, clinical, laboratory data and outcome were collected. Independent-samples t test was used for statistical analysis.Results The age at onset of CAEBV was from 2 months to 14.6 years (mean (5.3±3.3) years). At the time of onset, 43.4% patients had an infectious mononucleosis-like symptom. Most patients exhibited intermittent fever (92.5%, 49/53), hepatomegaly (81.1%, 43/53) and splenomegaly (77.4%, 41/53). Life-threatening complications including hemophagocytic syndrome (24.5%,13/53), interstitial pneumonia (24.5%, 13/53), hepatic failure (15.1%, 8/53) and malignant lymphoma (11.3%, 6/53) were also observed. The serum EBV DNA level in 23 patients with CAEBV was in the range of 5.05×102-4.60×106 copies/ml with a mean value of 103.7 copies/ml. Many patients with CAEBV generally had continuous symptoms during the observational period. Eleven out of 42 patients (26.2%) died 7 months to 3 years after onset. Deceased patients were more likely to have had lower platelet counts and albumin levels than the living patients (P<0.05 for all comparisons).Conclusions The study reveals that CAEBV in Chinese pediatric patients has a severe clinical course and prognosis is poor. Thrombocytopenia and decreases in albumin might potentially be risk factors for a poor prognosis. EBV loads should be measured and tissue should be stained on

    Full Text Available Disseminated Intravascular Coagulation (DIC is a pathological activation of coagulation (blood clotting mechanisms that happens in response to a variety of diseases. It involves the generation of intravascular fibrin (small blood c lots and the consumption of pro - coagulants and platelets. It results in the disruption of normal coagulation mechanism and abnormal bleeding occurs from the skin, the gastrointestinal tract, the respiratory tract and surgical wounds. It was the prospecti ve study of 60 patients of acute DIC, in which coagulation profile were studied from December 2010 to October 2012 . 40 controls were studied. Control group include healthy voluntary blood donors. The coagulation profile was studied and DIC scoring was p erformed using the International Society on Thrombosis and Haemostasis [ISTH] criteria. Among the coagulation profile, the sensitivity and specificity of the parameters to diagnose and to assess the severity of DIC, in the decreasing order of frequency wer e of platelet count, D - dimer, PT and APTT. Fibrinogen level was not depleted below the significant level (<1 gm/l in majority cases of DIC. According to the ISTH criteria, DIC scores among cases was ≥ 5.

    Abstract The authors present results obtained by a combination of clinical and empirical methods used in the evaluation of psychic change involving a single case study carried out during 2 years of nonmanualized psychodynamic psychotherapy (Barber & Crits-Christoph, 1993 ; Barber, Foltz, DeRubeis, & Landis, 2002 ). A multidimensional definition of change that includes clinical (psychoanalytic) and empirical perspectives is provided. The authors used material from supervision sessions and clinical meetings to assess the psychodynamic diagnosis and evolution. The following empirical techniques and instruments were used: core conflictual relationship theme (Luborsky & Crits-Christoph, 1990), Symptom Checklist-90-Revised (Derogatis, 1983), and Differential Elements for a Psychodynamic Diagnostic (C. M. López Moreno et al., 1998 ). Several markers of psychic change along the therapeutic process were found. The instruments proved to be sensitive to the changes obtained during the psychotherapy. Used together, the instruments allowed an integrated evaluation of the patient's evolution during the treatment.

    Monte Carlo simulations were used to study the interseed attenuation and the effect of tissue composition on prostate implant dosimetry. Using computed tomography images of postimplant analysis, the precise anatomy of the patient was considered voxel by voxel. The physical density of each voxel was set according to the Hounsfield Unit and the specific elemental composition of each voxel was set depending on the radiation-oncologist organ contours and the local density. Mixes of different tissues were available: muscle, prostate tissue, rectum tissue, adipose tissue, bone and prostate calcification. Typically, more than 300 combinations of elemental composition and density were used for each patient. The Monte Carlo dosimetry results were compared to the clinically approved TG43-based calculations for 30 patients. The results show an interseed attenuation of about 4.5% for the D90 parameter (minimal dose received by 90% of the target volume). The effect of the tissue composition varies from one patient to the other. Globally, the difference between the TG43-based calculations and the Monte Carlo results can reach more than 10 Gy for the D90 values. From a clinical perspective, the difference level can be non-negligible for the target volume and for the surrounding organs at risk.

    2014-01-01

    Cleidocranial dysplasia (CCD) is an autosomal-dominant disorder that occurs due to mutations in the Cbfa 1 gene, also called Runx 2, located on the short arm of chromosome 6, affecting osteoblast skeletal-specific bones that have intramembranous ossification. This condition is characterized by hypoplastic clavicles, short stature, and great clinical significance in the stomatognathic complex, with involvement of facial bones, changes in the eruption patterns, including multiple supernumerary and retained teeth. This study reports six subjects of the same family with CCD identified in the Dentistry Clinic of Oral Diagnosis Department, Universidade Paulista, Campus Sorocaba, Sao Paulo State, Brazil. All cases had clinical and radiographic aspects of this important condition, such as short stature, hypertelorism, severe mobility of the shoulders, and supernumerary and retained teeth. Due to the rare incidence and phenotypic manifestations, CCD can be easily misdiagnosed. The oral commitments are one of the main (functional and aesthetic) causes of complaints in these subjects; and a dentist must establish the diagnosis as early as possible, followed by behaviors and practices that can minimize harmful manifestations of the syndrome and improve health associated with oral and multidisciplinary integration offering improvements in quality of life of these subjects.

    Full Text Available An ectopic pregnancy is one in which fertilized ovum is implanted at the site other than normal uterine cavity.[1] Incidence of ectopic pregnancy is 1:160 deliveries.[2] Clinical presentation is variable from acute to chronic type. Due to its varied clinical presentation ectopic pregnancy poses great diagnostic difficulty both to obstetrician, physician and surgeons.[3] OBJECTIVE: To find out incidence in our study population and to evaluate symptomatically and clinical presentation in these patients. MATERIALS AND METHODS: Retrospective study of 34 ectopic pregnancies admitted and treated in Medical College hospital, Ujjain from 2010 to 2015 are included in the study. RESULTS: The incidence of ectopic pregnancy is more between the age group of 21-30years (73.52% and in Multigravida 64.71%. Infertility and previous tubal surgery are the high risk factors for tubal pregnancy. Pain in abdomen was present in all 34 cases, amenorrhea in 97.05% and bleeding per vagina in 76.47% cases. Syncopal attacks, vomiting were detected in 14.70% cases. Acute ectopic pregnancy was detected in 14.71% and chronic in 85.29% cases. 82.35% cases presented with adnexal mass, 79.41% with cervical motion tenderness, 50% with pallor, 32.35% with abdominal lump and tenderness and 11.76% with fullness in POD. CONCLUSION: Ectopic pregnancy is leading cause of maternal mortality in first trimester. In spite of advanced diagnostic techniques. It poses great diagnostic difficulties due to varied signs and symptoms. Previous tubal surgery pelvic inflammatory disease and infertility are the risk factors of tubal pregnancy.

    2015-01-01

    Clinical data warehouses often contain analogous data from disparate sources, resulting in heterogeneous formats and semantics. We have developed an approach that attempts to represent such phenotypic data in its most atomic form to facilitate aggregation. We illustrate this approach with human blood antigen typing (ABO-Rh) data drawn from the National Institutes of Health's Biomedical Translational Research Information System (BTRIS). In applying the method to actual patient data, we discovered a 2% incidence of changed blood types. We believe our approach can be applied to any institution's data to obtain comparable patient phenotypes. The actual discrepant blood type data will form the basis for a future study of the reasons for blood typing variation.

    Large clinical trials databases, developed over the course of a comprehensive clinical trial programme, represent an invaluable resource for clinical researchers. Data mining projects sponsored by industry that use these databases, however, are often not viewed favourably in the academic medical...... community because of concerns that commercial, rather than scientific, goals are the primary purpose of such endeavours. Thus, there are few examples of sustained collaboration between leading academic clinical researchers and industry professionals in a large-scale data mining project. We present here...

    A Paediatric Investigation Plan (PIP) is a development plan that aims to ensure that sufficient data are obtained through studies in paediatrics to support the generation of marketing authorisation of medicines for children. This paper highlights some practical considerations and challenges with respect to PIP submissions and paediatric clinical trials during the pharmaceutical development phase, using the FP7-funded Clonidine for Sedation of Paediatric Patients in the Intensive Care Unit (CloSed) project as a case study. Examples discussed include challenges and considerations regarding formulation development, blinding and randomisation, product labelling and shipment and clinical trial requirements versus requirements for marketing authorisation. A significant quantity of information is required for PIP submissions and it is hoped that future applicants may benefit from an insight into some critical considerations and challenges faced in the CloSed project.

Immune activation pre-cART may predict clinical progression in cART initiators. Methods A case-cohort study (n=470) within the multinational Prospective Evaluation of Antiretrovirals in Resource-Limited Settings (PEARLS) clinical trial (1571 HIV treatment-naïve adults who initiated cART; CD4+ T cell count <300 cells/mm3; nine countries) was conducted. A subcohort of 30 participants/country was randomly selected; additional cases were added from the main cohort. Cases (n=236 [random subcohort–36; main cohort–200]) had clinical progression (incident WHO Stage 3/4 event or death) within 96 weeks following cART initiation. Immune activation biomarkers were quantified pre-cART. Associations between biomarkers and clinical progression were examined using weighted multivariable Cox-proportional hazards models. Results Median age was 35 years, 45% were women, 49% black, 31% Asian, and 9% white. Median CD4+ T-cell count was 167 cells/mm3. In multivariate analysis, highest quartile CRP concentration (adjusted hazards ratio [aHR] 2.53, 95%CI 1.02-6.28) and CD4+ T-cell activation (aHR 5.18, 95CI 1.09-24.47) were associated with primary outcomes, compared to lowest quartiles. sCD14 had a trend towards association with clinical failure (aHR 2.24, 95%CI 0.96–5.21). Conclusions Measuring CRP and CD4+ T-cell activation may identify patients with CD4+ T cell counts < 300 cells/mm3 at risk for early clinical progression when initiating cART. Additional vigilance and symptom-based screening may be required in this subset of patients even after beginning cART. PMID:26017661

  4. Health Reform and its Impact on Healthcare Workers: A Case Study of the National Clinical Hospital of Cordova, Argentina

    Full Text Available Since the mid 1990’s, health in Argentina has no longer been considered a social function of the State but was transformed into a market commodity. Neoliberal decentralization favored the introduction of corporate methods and incentivized privatization. In practice, this led to self-management for hospitals, deregulation of social services and incorporation of private capital to the public health business. This exploratory study looks at the impact of these reforms in the public health services sector. It analyzes living and working conditions, changes produced in the organization of work and their effect on labor relations and on participation in union, political and social activities by workers at the National Clinical Hospital of Cordoba, Argentina. Data was primarily collected through an interview survey of a convenience sample of 68 workers from the non-teaching staff; this represents 10% of the total professional, administrative and maintenance staff of the hospital. The interviews demonstrate deterioration in income and living conditions. Hospital self-management for these workers led to increased competition, the fragmentation in the work spaces, tension and the distrust between co-workers, as well as increased intensity in the workload of some employees. The profile of these healthcare workers is structured and marked by silence, the resolution of the conflicts by means of individual action in the workplace, and minimal participation in social-political-union or community organizations.

    Bone angiosarcomas, especially vertebral angiosarcomas, are very rare. There are no studies based on large clinical samples in the literature, and only a few single case reports can be found. The symptoms of the disease are not specific. It is usually detected incidentally or at a late stage when pathological vertebral fractures or neurological complications occur. Diagnostic imaging and history help to recognize the tumour behind the symptoms, but do not allow accurate clinical diagnosis. The basis for a diagnosis is the histopathological examination supported by immunohistochemistry (IHC) assays. The case of a 26-year-old woman with an angiosarcoma involving the eighth thoracic vertebra we report reflects diagnostic problems adversely affecting the efficacy and accuracy of treatment offered to patients. The patient underwent three surgeries of the spine, including two biopsies. A needle biopsy did not provide sufficient information for the diagnosis. An open excisional biopsy, which at the same time temporarily reduced neurological deficits in the patient, was the only chance to obtain an accurate diagnosis. The third surgery was posterior decompression of the spinal cord due to the rapidly escalating paraparesis. It was not until 8 weeks later that the final diagnosis was established. At that time, the patient could not be qualified for any supplementary treatment. The patient died in hospital 6 months after the onset of disease. PMID:26468177

    Full Text Available Aim: The aim was to analyze general incidence, age incidence, laterality, common mode of presentation, staging of the tumor, radiological evidence, histopathological confirmation, management and follow-up of cases, which were diagnosed as retinoblastoma. Design: Interventional case series study from April 1997 to March 2000. Materials and Methods: Detailed history regarding the symptoms such as white reflex, watering, pain, redness, protrusion of eyeball, squint, hyphema, and defective vision were obtained. Family history regarding consanguinity between parents, health of the siblings and other relatives were recorded. Ocular examination included vision, pupillary reaction, detailed fundus examination, ocular tension, and corneal diameter. Investigations included X-ray orbit and skull, computed tomography scan orbit and brain, B-scan orbit, serum and aqueous lactate dehydrogenase; enucleated eyes were subjected to holoprosencephaly (HPE. Enucleation, radiotherapy, cryotherapy and chemotherapy were modalities of treatment. The empty socket and the other apparently normal eye were examined carefully at each visit. Results: The incidence of retinoblastoma is less when compared to other diseases of the eye. There was no sex predilection. Most of the cases diagnosed were sporadic and unilateral. Age of onset is earlier for bilateral cases than unilateral cases. Consanguinity bears close relationship with bilateral involvement. Predominant clinical sign is white reflex in the pupillary area. Majority of cases presented in the second stage of the disease. Enucleation plays a greater role in the management of retinoblastoma. HPE should include several sections of the optic nerve to find out skip lesions.

    Differences in genetic origin between nodal and extranodal diffuse large B-cell lymphomas (DLBCL) exist. Using population-based data from the registry of the Danish Lymphoma Group, the present study is the first to analyse clinical implications of nodal versus extranodal presentation of DLBCL....... Of 4786 newly diagnosed non-Hodgkin's lymphoma patients in a 16-year period, 1575 (33%) had DLBCL. The annual incidence rate was 2.9 per 100 000; 40% were extranodal. The clinical profile of patients with extranodal DLBCL was different from the nodal DLBCL patients. Extranodal DLBCL was associated...... with older age and poorer performance score, but also lower tumour burden. In extranodal DLBCL, 51% of the cases were stage I and 36% were stage IV, whereas the patients were relatively equally distributed between the four stages in nodal DLBCL. For stage I patients, extranodal DLBCL was independently...

  11. Collaborative research between academia and industry using a large clinical trial database: a case study in Alzheimer's disease

    2011-10-01

    Full Text Available Abstract Background Large clinical trials databases, developed over the course of a comprehensive clinical trial programme, represent an invaluable resource for clinical researchers. Data mining projects sponsored by industry that use these databases, however, are often not viewed favourably in the academic medical community because of concerns that commercial, rather than scientific, goals are the primary purpose of such endeavours. Thus, there are few examples of sustained collaboration between leading academic clinical researchers and industry professionals in a large-scale data mining project. We present here a successful example of this type of collaboration in the field of dementia. Methods The Donepezil Data Repository comprised 18 randomised, controlled trials conducted between 1991 and 2005. The project team at Pfizer determined that the data mining process should be guided by a diverse group of leading Alzheimer's disease clinical researchers called the "Expert Working Group." After development of a list of potential faculty members, invitations were extended and a group of seven members was assembled. The Working Group met regularly with Eisai/Pfizer clinicians and statisticians to discuss the data, identify issues that were currently of interest in the academic and clinical communities that might lend themselves to investigation using these data, and note gaps in understanding or knowledge of Alzheimer's disease that these data could address. Leadership was provided by the Pfizer Clinical Development team leader; Working Group members rotated responsibility for being lead and co-lead for each investigation and resultant publication. Results Six manuscripts, each published in a leading subspecialty journal, resulted from the group's work. Another project resulted in poster presentations at international congresses and two were cancelled due to resource constraints. Conclusions The experience represents a particular approach to

    Full Text Available Background and Goals. In light of current knowledge, it seems that alternations underlying GISTs are well explained, although all that is enhanced by various aspects on a daily basis. More recently, attention has been pointed towards exosomes as important particles able to modify healthy and also diseased tissues including cancer. The goal of the present study was an analysis of CD9, CD63, and GLUT-1 as a marker of hypoxia status within 54 cases of GIST and evaluation of their predictive value. Methods. 54 cases of patients suffering from GIST were enrolled into the study, predominantly in the gastric location. All operated cases had no Imatinib and other chemotherapies up to the day of operation. Expression of targeted proteins was performed by immunohistochemistry and, after that, the results with tabulated clinical data were compared by Kaplan-Meier method and multivariate Cox proportional hazard model of statistical analysis. Results. Our results presented a marked dependence of worsening clinical outcome with high expression CD63 (p=0.008 as well as with GLUT-1 (p=0.014. We noted a strict correlation of GLUT-1 expression with CD63 expression (p=0.03, which could confirm the thesis about the contribution of exosomes in intratumoural hypoxia status. The collected material did not confirm CD9 contribution. Conclusions. As presented here, CD63 and GLUT-1 have a prognostic value in GIST cases. The results confirm the other studies in this scope and can be used in future as an additional prognostic factor.

    Full Text Available BACKGROUND: There is a highly variable asymptomatic period of beta cell destruction prior to the clinical presentation of type1 diabetes. It is not well known what triggers type 1 diabetes to become a clinically overt disease. This explorative study aimed to identify the association between disease history/medication use and the clinical manifestation of type 1 diabetes. METHODOLOGY/PRINCIPAL FINDINGS: An explorative case control study was conducted in the Dutch PHARMO Record Linkage System. Cases (n = 1,107 were younger than 25 years and had at least 2 insulin prescriptions between 1999 and 2009. For each case, up to 4 controls (without any prescription for the glucose lowering medications (n = 4,424 were matched by age and sex. Conditional logistic regression analysis was used to evaluate the association between disease history/medication use in the year prior to the diagnosis of type 1 diabetes and clinical manifestation of this disease. Type1 diabetes was significantly associated with a history of mental disorder (odds ratio (OR 8.0, 95% confidence interval (CI 1.5-43.7, anemia (OR 5.1, 95% CI 1.1-22.9, and disease of digestive system (OR 2.6, 95% CI 1.2-5.5. The following drug exposures were significantly associated with the clinical manifestation of type 1 diabetes: "systemic hormonal preparations" (OR 1.7, 95% CI 1.1-2.6, medications for "blood and blood forming organs" (OR 1.6, 95% CI 1.1-2.6, "alimentary tract and metabolism" (OR 1.3, 95% CI 1.1-1.6, and "anti-infectives for systemic use" (OR 1.2, 95% CI 1.01-1.4. CONCLUSIONS: Our explorative study demonstrated that in the year prior to the presentation of type 1 diabetes in children and young adults, hospitalization for a diverse group of diseases and drug exposures were significantly more prevalent compared with age- and sex-matched diabetes-free controls.

    This paper describes the data transformation pipeline defined to support the integration of a new clinical site in a standards-based semantic interoperability environment. The available datasets combined structured and free-text patient data in Dutch, collected in the context of radiation therapy in several cancer types. Our approach aims at both efficiency and data quality. We combine custom-developed scripts, standard tools and manual validation by clinical and knowledge experts. We identified key challenges emerging from the several sources of heterogeneity in our case study (systems, language, data structure, clinical domain) and implemented solutions that we will further generalize for the integration of new sites. We conclude that the required effort for data transformation is manageable which supports the feasibility of our semantic interoperability solution. The achieved semantic interoperability will be leveraged for the deployment and evaluation at the clinical site of applications enabling secondary use of care data for research. This work has been funded by the European Commission through the INTEGRATE (FP7-ICT-2009-6-270253) and EURECA (FP7-ICT-2011-288048) projects. PMID:26306242

    [Purpose] This study investigated the effects of real-time feedback using infrared camera recognition technology-based augmented reality in gait training for children with cerebral palsy. [Subjects] Two subjects with cerebral palsy were recruited. [Methods] In this study, augmented reality based real-time feedback training was conducted for the subjects in two 30-minute sessions per week for four weeks. Spatiotemporal gait parameters were used to measure the effect of augmented reality-based real-time feedback training. [Results] Velocity, cadence, bilateral step and stride length, and functional ambulation improved after the intervention in both cases. [Conclusion] Although additional follow-up studies of the augmented reality based real-time feedback training are required, the results of this study demonstrate that it improved the gait ability of two children with cerebral palsy. These findings suggest a variety of applications of conservative therapeutic methods which require future clinical trials. PMID:27190489

    Full Text Available Background: The current strategy for leprosy control depends mainly on early case detection and providing the recommended multidrug therapy (MDT dosage. Understanding the molecular mechanisms of drug resistance to each of these drugs is essential in providing effective treatment and preventing the spread of resistant strains in the community. The progress of molecular biology research provides a very efficient opportunity for the diagnosis of drug resistance by in vitro method. Aim: We aimed to investigate the point mutations within the rpoB gene region of the Mycobacterium leprae genome, which are responsible for resistance to rifampicin, in order to determine the emergence of drug resistance in leprosy in the Kolkata region of West Bengal. Methods: A total of 50 patients with a relapse of leprosy were enrolled in the study. Skin smears were obtained for estimation of bacillary index and biopsies were obtained in 70% alcohol for extraction of DNA. The extracted DNA was amplified by M. leprae-polymerase chain reaction (PCR targeting rpoB gene region. Every single nucleotide base in the sequence is aligned to reference sequence and identity gaps were determined by NCBI - BLAST. Later in-silico analysis was done to identify the changes in the translated protein sequences. Results: A mutation at the base pair position 2275405 where G is replaced by C in the M. leprae genome, which corresponds to the coding region of rpoB gene (279 bp - 2275228 to2275506, was observed in two patients. This missense mutation in CAC codon brings about a glutamic acid to histidine change in the amino acid sequence of RNA polymerase beta subunit at the position 442 (Glu442His, a region specific for rifampicin interaction, which might be responsible for unresponsiveness to rifampicin by manifesting a stable bacteriological index in these 2 patients even after completion of 24 months of multibacillary multi-drug therapy (MB-MDT. Limitations: The major limitations of

    Prenatal diagnosis was requested for an undiagnosed eye disease showing X-linked inheritance in a family. No medical records existed for the affected family members..Mapping of the X chromosome and candidate gene mutation screening i-dentified a c.C267A[p.F89L] mutation in NPD previously de-scribed as possibly causing Norrie disease..The detection of the c.C267A[p.F89L] variant in another unrelated family con-firms the pathogenic nature of the mutation for the Norrie dis-ease phenotype. Gene mapping, haplotype analysis, and can-didate gene screening have been previously utilized in research applications but were applied here in a diagnostic setting due to the scarcity of available clinical information..The clinical diagnosis and mutation identification were critical for provid-ing proper genetic counseling and prenatal diagnosis for this family.

  4. Clinical and neuroradiological study on adult cases of familial microcephaly associated with mental retardation and convulsive seizure

    International Nuclear Information System (INIS)

    Microcephaly results from various causes, some genetic and some non-genetic. Recently, we encountered two families with microcephaly, mental retardation and convulsive seizure. These conform to an autosomal recessive mode of inheritance. All adult cases were analyzed to describe the characteristic neuroradiographic findings. Although each presented a similar neurologic outlook, two cases secondarily resulting from infection or injuries to the developing brain during postnatal periods showed a specific variation. Skull X-P and CT scan of these two cases showed thickening of the carvarium, predominantly fronto-parietal lobe atrophy of the cerebrum, enlargement of the ventricle, and compensatory hypertrophy of sinuses. Magnetic resonance imaging (MRI) showed severe micropolygyria and hypogenesis of corpus callosum. Abnormalities such as skull X-P, CT scan and MRI were severer in the secondary than in the primary microcephalics. Although brain volume was reduced, the volume ratio of cortex to white watter was similar to that of normal brain. MRI on severe cases of microcephaly revealed a high signal intensity in inversion-recovery images on the brain stem where markedly atrophy was noted. In adult microcephaly, the extent of cerebral development was thought to be reflected in the corpus callosum and brain stem where neuron fibers were densely gathered. (author)

    Clinical characteristics and outcome among dengue patients with and without human immunodeficiency virus (HIV) infection remain elusive. A total of 10 dengue virus (DENV)-HIV Chinese patients were compared with 40 Chinese dengue patients without HIV, who were matched for age, gender, type of care received, methods, and year of dengue diagnosis from 2005 to 2008. Univariate and multivariate conditional logistics regression were applied. DENV-HIV patients were significantly associated with the World Health Organization (WHO) 2009 severe dengue (conditional odds ratio [COR] = 5.72; 95% confidence interval [CI] = 1.01-32.64) but not with the WHO 1997 dengue hemorrhagic fever/dengue shock syndrome (COR = 0.40; 95% CI = 0.09-1.71). This is mainly due to severe plasma leakage and the lack of hemorrhagic manifestations. Hospitalization duration was longer for DENV-HIV patients (10.5 days; interquartile range [IQR] = 5.5-26.3 days) compared with dengue patients (5 days; IQR = 4-6 days). There were no significant differences in presentation of clinical warning signs and symptoms at admission and during hospitalization, except for rash (adjusted COR [ACOR] = 0.06; 95% CI = 0.03-0.92). DENV-HIV patients were associated with higher pulse rate (ACOR = 1.13; 95% CI = 1.02-1.25), eosinophils proportion (ACOR = 3.07; 95% CI = 1.12-8.41) and lower hematocrit level (ACOR = 0.79; 95% CI = 0.64-0.98) compared with dengue patients. Even though DENV-HIV patients may present similarly to dengue patients, they may be more likely to have severe dengue outcome. Hence, close monitoring of DENV-HIV patients is highly recommended as part of dengue clinical care and management.

STUDY DESIGN: One hundred fifty-eight triploid pregnancies were identified in hospitals in Western Denmark from April 1986 to April 2010. Clinical data...... than MMP cases (P cases, the possible karyotypes had similar frequencies, whereas, in PPM cases, 43% had the karyotype 69, XXX, 51% had the karyotype 69, XXY, and 6% had the karyotype 69, XYY. Molar phenotype was seen only in PPM cases. However, PPM cases with a nonmolar phenotype were...... also seen. For both parental genotypes, various fetal phenotypes were seen at autopsy. Levels of human chorionic gonadotropin in maternal serum were low in MMP cases and varying in PPM cases, some being as low as in the MMP cases. CONCLUSION: In a triploid pregnancy, suspicion of hydatidiform mole...

  7. Clinical studies on cerebral infarction

    International Nuclear Information System (INIS)

    Hemorrhagic infarction (HI) is termed as the infarction in which a large part of the necrotic tissue is stippled with small hemorrhage. The pathogenetic mechanism of this disease still remains controversial. Cerebral infarction has long been divided into two subtypes-thrombosis and embolism-according to the pathogenetic mechanisms. Clinical studies were carried out in 31 cases of HI with cerebral thrombosis. CT findings of these cases were classified into five groups according to both size of low density area which indicates regions of infarction and distribution of arterial supply. The low density area of Type I-Type III were observed in the area of the middle cerebral artery. That of Type IV was observed in the area of the internal capsule and basal ganglia. That of Type V was observed in the area of the posterior cerebral artery. CT reveals two patterns of HI -pattern A and pattern B-. The CT finding of pattern A is appearance of high density area in the low density area. The CT finding of pattern B is appearance of iso density area in the low density area. rCBF was measured by 133Xe inhalation technique in 21 patients with CT type I, II and III. Thereafter, with regard to the various findings in CT, the clinical findings and CBF findings, a comparative study was carried out on these ten groups. From the results of present studies, it is concluded that sequential changes of CBF in cases with pattern A are different from those with pattern B, and that CBF measurement does not permit an estimation of a patient's chance for functionary recovery after a stroke in acute and subacute stage but permits estimation of functional outcome in chronic stage.

    The new NHS requires transformational leadership; people with the knowledge and motivation to make effective change combined with an understanding of the system they work in. The aim of the Practice Leaders' Programme (PLP) is to generate the conditions needed to focus the energy and collaborative creativity required for innovation to enhance leadership skills across the health economy improving patient care. The PLP engaged 60 local leaders from central England in a new approach enabling them to influence others. It has informed educational policy and practice and helped change professional behaviours. Each participant implemented improvements in care and participated in six action learning sets (ALS) and up to six coaching sessions. Evidence of progress, learning and impact was identified in project reports, reflective diaries and evaluations. The ALS brought together key individuals from clinical and management disciplines across a diverse organisation to redesign a system by developing a shared vision for improving the quality of patient care. The links forged, the projects initiated, and the skills cultivated through the PLP produced ongoing benefits and outcomes beyond the course itself. Coaching sessions helped participants focus their efforts to achieve maximum impact and to become resilient in managing service change effectively. The programme has evolved over four years, building on recommendations from external evaluation which identified statistically significant increases in leadership competences. Further enhancement of this programme secured an International Health Improvement Award. Three key findings of positive impact have emerged; personal growth, service improvement, and legacy and sustainability.

    Full Text Available Introduction: In this environment, previous workers have reported on the challenges of managing large sized ameloblastoma of the jaws with less than adequate facilities. The aim of this review is to present the management of 68 cases of ameloblastoma with emphasis on surgical care. Materials and Methods: Retrospective survey of case notes of patients with histopathologic diagnosis of ameloblastoma (using the criteria of Barnes et al., 2005 seen between January 2006 and August 2010 at the Maxillofacial Unit, Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria was undertaken. Data collected includes histopathological diagnosis, age, gender, clinical information on site of lesion, form of intubation and surgical procedure performed. Results: Out of 94 patients, 68 with histological diagnosis of ameloblastoma (59 mandibular and 9 maxillary were operated within the study period. The remainder (26 was not treated in hospital. Among 68 patients treated, more were males (38 than females (30, giving a male to female ratio of 1.3:1. The age range was between 14 and 74 years (mean-standard deviation. The duration of the symptoms ranged from 7 months to 24 years, most were follicular ameloblastoma (n = 13 followed by acanthomatous type (n = 7. Endotracheal intubation was the most common (n = 55 followed by fiber optic laryngoscopy (n = 8. The surgical approach most used was extended Risdon with intraoral (n = 24 followed by extended Risdon with lip split and intraoral (n = 17. Segmental resection (en block formed the bulk of our procedures (n = 22 followed by subtotal mandibulectomy (n = 16. Conclusion: The treatment of ameloblastoma remains controversial. Its destructive nature has left patients with wide defects difficult to reconstruct.

    In the last few years there has been an increase in the number of clinical nurse specialists (CNSs) working in cancer care throughout the UK. This paper examines the issues raised by the proliferation of site-specific cancer CNS posts, developed to give a 'nursing lead' for a particular tumour type. The issues common to all CNS posts are exacerbated when a number of specialists are involved in the cancer journey, causing potential fragmentation and confusion. Key issues need to be addressed if the role is to remain credible, and ensure clarity for patients and the multiprofessional team. These include role clarification, sensitive integration, interface with other cancer CNSs and the multiprofessional team, evaluation, cost, education and training, recruitment and succession planning and the 'career cul-de-sac'. Cancer nursing's response to these challenges will set the professional agenda for education, training and future models of service delivery. PMID:12849018

    40 cases of senile psoriasis were treated by the therapeutic principle of replenishing qi to activate blood,and the changes of T lymphocyte subgroups and indexes of haemorheology were observed. The results showed that CD4 was significantly increased, CDs significantly decreased, and the CD4/CD8 ratio significantly raised; and that the specific viscosity of whole blood at high shearing rate, and at low shearing rate, the specific viscosity of plasma, packed cell volume, and fibrinogen all significantly decreased after treatment. It is therefore concluded that the therapeutic method of replenishing qi to activate blood can exert an effect of improving immunologic function and blood circulation.

    Dengue is an infectious disease caused by a flavivirus, with four serotypes, transmitted by the mosquito Aedes aegypti. In Mexico it is a public health problem, especially in the region of central and southeast of the country. The disease can be asymptomatic or present serious forms and even death. It is confirmed by detection of the NS1 Antigen; IgM antibodies, polymerase chain reaction and virus isolation. The vertical transmission to de newborn has been little studied. 7 cases in neonates from November to December 2011 are reported. All patients were male, obtained by caesarean section between 34 and 40 weeks of gestation, whose mothers were enrolled with fever and symptoms associated with dengue disease and serology positive for dengue. Six with positive AgNS1 and one positive IgM; one mother died. All the newborns had positive serology for dengue, 4 with positive AgNS1 and 3 positive IgM. The clinical features of the newborn ranged from asymptomatic to one serious dengue fever, shock and hemorrhage. The symptomatic 6 attended with thrombocytopenia, changes in temperature and unspecific disturbance.

    Ectopic pregnancy remains a leading cause of maternal mortality and accounts for a sizeable proportion of infertility and ectopic recurrence. The possibility that a woman is experiencing an ectopic pregnancy must be considered when evaluating a woman, especially a sterilized woman, who has a possible pregnancy, amenorrhea, abdominal pain, or abnormal bleeding; studies have found that one in six pregnancies occurring after tubal sterilization are ectopic. The authors present a clinical study of 82 cases of ectopic pregnancy admitted to the department of Obstetrics and Gynecology of Mahatma Gandhi Institute of Medical Sciences, Sevagram. Cases of ectopic pregnancy represent 0.99% of total obstetric admissions, of whom 69.51% were diagnosed as such on admission. 40.24% of the women were older than 30 years, while 34.14% were elderly beyond third parity. 70.73% of the women presented before missing their second period. Patients presented with multiple complaints, but the most common was abdominal pain reported by 61.70%. 78.04% were admitted with an acute abdomen, but shock was present in only 7.14% of cases. The main surgical treatment modality was salpingectomy among 59.75%. There was no maternal mortality through postoperative morbidity in the form of paralytic ileus, although fever did occur in some women.

    An increasing adoption of electronic medical records has made information more accessible to clinicians and researchers through dedicated systems such as HIS, RIS and PACS. The speed and the amount at which information are generated in a multi-institutional clinical study make the problem complicated compared to day-to-day hospital workflow. Often, increased access to the information does not translate into the efficient use of that information. Therefore, it becomes crucial to establish models which can be used to organize and visualize multi-disciplinary data. Good visualization in turn makes it easy for clinical decision-makers to reach a conclusion within a small span of time. In a clinical study involving multi-disciplinary data and multiple user groups who need access to the same data and presentation states based on the stage of the clinical trial or the task are crucial within the workflow. Therefore, in order to demonstrate the conceptual system design and system workflow, we will be presenting a clinical trial based on application of proton beam for radiosurgery which will utilize our proposed system. For demonstrating user role and visualization design purposes, we will be focusing on three different user groups which are researchers involved in patient enrollment and recruitment, clinicians involved in treatment and imaging review and lastly the principle investigators involved in monitoring progress of clinical study. Also datasets for each phase of the clinical study including preclinical and clinical data as it related to subject enrollment, subject recruitment (classifier), treatment (DICOM), imaging, and pathological analysis (protein staining) of outcomes.

    Paralytic shellfish poisoning (PSP), a potentially fatal foodborne illness, is often diagnosed anecdotally based on symptoms and dietary history. The neurotoxins responsible for PSP, collectively referred to as the saxitoxins or paralytic shellfish toxins (PSTs), are natural toxins, produced by certain dinoflagellates, that may accumulate in seafood, particularly filter-feeding bivalves. Illnesses are rare because of effective monitoring programs, yet occasional poisonings occur. Rarely are contaminated food and human clinical samples (e.g., urine and serum) available for testing. There are currently few methods, none of which are validated, for determining PSTs in clinical matrices. This study evaluated AOAC (Association of Analytical Communities) Official Method of Analysis (OMA) 2005.06. [AOAC Official Method 2005.06 Paralytic Shellfish Poisoning Toxins in Shellfish: Prechormatographic Oxidation and Liquid Chromatography with Fluorescence Detection. In Official Methods of Analysis of AOAC International ], validated only for shellfish extracts, for its extension to human urine and serum samples. Initial assessment of control urine and serum matrices resulted in a sample cleanup modification when working with urine to remove hippuric acid, a natural urinary compound of environmental/dietary origin, which co-eluted with saxitoxin. Commercially available urine and serum matrices were then quantitatively spiked with PSTs that were available as certified reference materials (STX, dcSTX, B1, GTX2/3, C1/2, NEO, and GTX1/4) to assess method performance characteristics. The method was subsequently applied successfully to a PSP case study that occurred in July 2007 in Maine. Not only were PSTs identified in the patient urine and serum samples, the measured time series also led to the first report of human PST-specific urinary elimination rates. The LC-FD data generated from this case study compared remarkably well to results obtained using AOAC OMA 2011.27 [AOAC Official

    Maintaining healthy parodontium during teeth restoration procedures is an indispensable condition for obtain- ing regular functionning and esthetics. Thus, the knowledge of correct anatomy and the influence of filling and complement on paradontium tissue is vital. Difficulty in maintaining appropriate gingival biological width (GBW) is a frequent problem encountered in this type of reconstruction. Preservation of unchanged biological width conditions predictible treatment result and, what is more, lack of inflammatory lesions in marginal parodontium. The ideal situation for parodontium is localizing the filling/complement border supragingivaly, which is at least 3 mm from alveolar process edge. In the case, when the above conditions are impossible to fulfil, elongation of clinical crown is a metod of choice. The effect is possible to achieve by surgical treatment or combined orthodontic - surgical treatment. Surgical treatment is faster and preferred procedure for indirect reconstruction, where achieving high clinical crown is necessary. Three clinical cases of performing method of surgical clinical crown elongation were presented in the article. Performing the described procedure enables correct tooth crown reconstruction and, what is most important, keeping individual toothing.

    Objective: The evidence in medical literature is that a beneficial analgesic effect can only be obtained by employing laser radiation of relatively low power density and wavelengths which are able to penetrate tissue. For this reason the semiconductor, or laser diode (GaAs, 904 nm), is the most appropriate choice in pain-reduction therapy. Summary Background Data: Low power laser (or LLL) acts on the Prostaglandins synthesis, increases the endorphins synthesis in the Rolando gelatinous substance and in the dorsal horn of the spinal cord. The L-Arginine, which is the classic substrate of nitric oxide, carries on vasodilatory and anti- inflammatory action. Methods: Treatment was carried out on 447 cases and 435 patients (250 women and 185 men) between 20th May 1987 and 31st December 1999. The patients, whose age ranged from 25 to 70, were suffering from rheumatic, degenerative and traumatic pathologies as well as cutaneous ulcers. The majority of patients had been seen by orthopaedists and rheumatologists and had undergone x-ray, ultrasound scan, etc. All patients had previously received drug-based treatment and/or physiotherapy, with poor results. Two thirds were experiencing acute symptomatic pain, while the others presented a chronic pathology with recurrent crises. We used a pulsed IR diode laser, GaAs emitting at 904 nm. Frequency of treatment: 1 application per day for 5 consecutive days, followed by a 2-day interval. The percentage reduction in symptoms or improvement in functional status were determined on the basis of objective analysis as it happens in the Legal and Insurance Medicine field. Results: Very good results were achieved especially with cases of symptomatic osteoarthritis of the cervical vertebrae, with sport-related injuries, epicondylitis, osteoarthritis of the knee, periarthritis and with cutaneous ulcers. The beneficial action of the LLLT in the latter pathology is linked to the increase in collagen and to fibroblast proliferation. The total

    Full Text Available Abstract Background HIV-infected subjects have high incidence rates of Staphylococcus aureus infections, with both methicillin-susceptible and methicillin-resistant (MRSA strains. Possible explanations could include the high burden of colonization, the behavioral risk factors, and the frequent exposures to health care facilities of HIV-infected patients. The purpose of the study was to assess the risk factors for clinically- significant methicillin-resistant Staphylococcus aureus (CS-MRSA infections in HIV-infected patients admitted to Infectious Diseases Units. Methods From January 1, 2002 to December 31, 2005, we conducted a retrospective case-control (1:2 study. We identified all the cases of CS-MRSA infections in HIV-infected patients admitted to the National Institute for Infectious Diseases (INMI "Lazzaro Spallanzani" in the 4-year study period. A conditional logistic regression model was used to identify risk factors for CS-MRSA infection. Results We found 27 CS-MRSA infections, i.e. 0.9 CS-MRSA infections per 100 HIV-infected individuals cared for in our Institute. At multivariate analysis, independent predictors of CS-MRSA infection were cumulative hospital stay, invasive procedures in the previous year, and low CD4 cell count. Particularly, the risk for CS-MRSA increased by 14% per an increase of 5 days hospitalization in the previous year. Finally, we identified a low frequency of community-acquired MRSA infections (only 1 of 27; 3.7% among HIV-infected patients. Conclusion Clinicians should be aware of the risk for CS-MRSA infection in the clinical management of HIV-infected patients, especially in those patients with a low CD4 cell count, longer previous hospital stay, and previous invasive procedures.

    With the advent of antibiotic resistance, pathogenic bacteria have become a major threat in cases of neonatal sepsis; however, guidelines for treatment have not yet been standardized. In this study, 15 cases of neonatal Streptococcus agalactiae sepsis from our hospital were retrospectively analyzed. Of these, nine cases showed early-onset and six cases showed late-onset sepsis. Pathogens were characterized by genotyping and antibiotic sensitivity tests on blood cultures. Results demonstrated that in cases with early-onset sepsis, clinical manifestations affected mainly the respiratory tract, while late-onset sepsis was accompanied by intracranial infection. Therefore, we suggest including a cerebrospinal fluid examination when diagnosing neonatal sepsis. Bacterial genotyping indicated the bacteria were mainly type Ib, Ia, and III S. agalactiae. We recommend treatment with penicillin or ampicillin, since bacteria were resistant to clindamycin and tetracycline. In conclusion, our results provide valuable information for the clinical treatment of S. agalactiae sepsis in neonatal infants. PMID:27323190

    The aim of this study was to investigate whether the compression force used with conventional mammography can be reduced with breast tomo-synthesis (BT), without adversely affecting the visualisation of normal and pathological structures. Forty-five women were examined with BT using full (same as for 2D mammography) and half compression force. Both examinations were performed with the same acquisition parameters. A total of 103 paired structure images were evaluated according to specified image quality criteria. Three experienced radiologists participated in the study. They had to make a forced choice, i.e. choose the image they felt best fulfilled the image quality criteria. The results showed no evident difference in the image quality, indicating that BT may be performed with substantially less compression force compared with 2D mammography. A majority of the examined women felt that half compression was more comfortable than full compression. (authors)

    Full Text Available Abstract Background Increased detection of tuberculosis (TB using intensified or active case finding (ICF is one of the cornerstones of the Stop TB Strategy, and contrasts with passive case finding (PCF which relies on self-reported symptoms. There is no clear guidance on implementation strategies. We implemented ICF in addition to ongoing PCF in our large urban HIV clinic in July 2010 using a twice-daily announcement screen method by a trained peer educator, asking waiting patients to self-refer to a trained peer supporter for screening of TB symptoms. We sought to determine the associated effect on TB case detection. Methods Suspects were investigated by sputum smear, chest X-ray and ultrasound, if indicated. Routinely collected clinical and laboratory data were merged with the ICF register and TB clinic data for patients attending the clinic in 2010. We compared the yield of TB cases (defined as the prevalence of newly diagnosed TB cases in the screened population, the type of TB diagnosed and the total cost per TB case identified (in United States Dollars [USD] for the period before and after ICF implementation. Results Of the 20,456 patients who visited the clinic in 2010, 614 were identified as TB suspects, 220 pre-ICF and 394 post-ICF (229 via PCF and 165 via ICF. The proportion diagnosed with TB dropped from 66% to 48% (60% in suspects identified through PCF and 31% through ICF. During the post-ICF period, TB suspects identified through ICF compared to PCF identification were more likely to be female, older, on ART and to have been enrolled in HIV care for a longer duration. The yield of combined PCF and ICF screening was 1.4% pre-ICF and 1.7% post-ICF with a cost per TB case identified of 12.29 USD and 21.80 USD, respectively. Conclusions Implementation of ICF in a large HIV clinic yielded more TB suspects and cases, but substantially increased costs and was unable to capture the majority of TB suspects who were referred for diagnosis

    Full Text Available There is a gap between proposed theoretical attachment theory frameworks, measures of attachment in the assessment phase and their relationship with changes in outcome after a psychodynamic oriented psychotherapy. Based on a clinical case study of a young woman with Panic Attack Disorder, this paper examined psychotherapy outcome findings comparing initial and post-treatment assessments, according to the mental functioning in S and M-axis of the Psychodynamic Diagnostic Manual (PDM. Treatment planning and post-treatment changes were described with the main aim to illustrate from a clinical point of view why a psycho-dynamic approach, with specific attention to an attachment theory stance, was considered the treatment of choice for this patient. The Symptom Check List 90 Revised (SCL-90-R and the Shedler-Westen Assessment Procedure (SWAP–200 were administered to detect patient’s symptomatic perception and clinician’s diagnostic points of view, respectively; the Adult Attachment Interview (AAI and the Adult Attachment Projective Picture System (AAP were also administered as to pay attention to patient’s unconscious internal organization and changes in defense processes. A qualitative description of how the treatment unfolded was included. Findings highlight the important contribution of attachment theory in a 22-month psychodynamic psychotherapy framework, promoting resolution of patient’s symptoms and adjustment.

    Background/Aims No clinical model exists to predict the occurrence of hepatocellular carcinoma in sustained virologic response-achieving (HCC after SVR) patients with chronic hepatitis C (CHC). Methods We performed a case-control study using a clinical database to research the risk factors for HCC after SVR. A predictive model based on risk factors was established, and the area under the receiver operating characteristic curve (AUC) was calculated. Results In the multivariate model, an initial diagnosis of compensated cirrhosis and post-SVR albumin reductions of 1 g/L were associated with 21.7-fold (95% CI, 4.2 to 112.3; p0, an AUC of 0.880, a sensitivity of 0.833, a specificity of 0.896, and a negative predictive value of 0.956. Conclusions An initial diagnosis of compensated cirrhosis combined with a post-SVR albumin value of ≤36.0 g/L predicts the occurrence of HCC after SVR in patients with CHC. PMID:27257023

    Full Text Available This study examined in real time the role of sleep and daydreaming as potentiating states for subsequent dissociation in depersonalization/derealization disorder (DDD. Research and theory suggests that dissociation may be exacerbated and maintained by a labile sleep-wake cycle in which ‘dream-like’ mentation intrudes into waking life and fuels dissociative symptoms. We explore and extend this idea by examining the state of daydreaming in dissociation. Daydreaming is a state of consciousness between dreaming and waking cognition that involves stimulus-independent and task-unrelated mentation. We report the results of a unique intensive N=1 study with an individual meeting diagnostic criteria for DDD. Using experience-sampling methodology, the participant rated (six times daily for 40 days current daydreaming, mood, and dissociative symptoms. At the start of each day sleep quality and duration was also rated. Daydreaming was reported on 45% of occasions and significantly predicted greater dissociation, in particular when daydreams were repetitive and negative (but not fanciful in content. These relationships were mediated by feelings of depression and anxiety. Sleep quality but not duration was a negative predictor of daily dissociation and also negatively predicted depression but not anxiety. Findings offer initial evidence that the occurrence and content of daydreams may act as potentiating states for heightened, in the moment, dissociation. The treatment implications of targeting sleep and daydreaming for dissociative disorders are discussed.

    Full Text Available Purpose: This retrospective study was done to report our experience with the management of patients with primary malignant tumors of minor salivary glands that were treated with various combinations of surgery, radiation, and chemotherapy and to review treatment outcome. Methods: The records of all patients with malignant minor salivary gland tumors presenting for treatment at our department between 2000 and 2010 were retrospectively reviewed. Variables were collected and outcome measures were defined in terms of overall survival, disease-free survival. Descriptive statistics were compiled and statistically evaluated. Survival was described using the Kaplan-Meier method. Results: Twenty eight patients (10 males and 18 females ranging in age from 18 to 80 years (median, 64 years met the criteria for inclusion in the study. The majority of tumors were located in the oral cavity (n = 20, followed by nasal cavity and paranasal sinuses (n = 8. Adenoid cystic carcinoma was the most common neoplasm (n = 18. All patients were treated with surgery as the primary modality. Neck dissection was performed in 18% of patients, and all patients (n = 28 were treated with adjuvant external beam radiation therapy to a dose of 50 to 60 Gy. The disease-free survival rate and overall survival at 5 years were 80% and 85%, respectively. Conclusion: Postoperative radiation therapy is effective in preventing local recurrence in most patients with minor salivary gland tumors after gross total excision.

    Pili torti also known as ‘twisted hairs’ (Latin: pili=hair; torti=twisted) is a rare, congenital or acquired clinical presentation, in which the hair shaft is flattened at irregular intervals and twisted 180º along its axis. It is clinically characterized by fragile, brittle, coarse and lusterless hairs, due to uneven light reflection on the twisted hair surface. Pili torti may be associated with neurological abnormalities and ectodermal dysplasias. There is no specifi c treatment for this condition, but it may improve spontaneously after puberty. We report a case of pili torti in a child who presented fragile, brittle, diffi cult to comb hair. The patient had no comorbidities. PMID:26312667

    Full Text Available Abstract Over the past 20 years, several proton beam treatment programs have been implemented throughout the United States. Increasingly, the number of new programs under development is growing. Proton beam therapy has the potential for improving tumor control and survival through dose escalation. It also has potential for reducing harm to normal organs through dose reduction. However, proton beam therapy is more costly than conventional x-ray therapy. This increased cost may be offset by improved function, improved quality of life, and reduced costs related to treating the late effects of therapy. Clinical research opportunities are abundant to determine which patients will gain the most benefit from proton beam therapy. We review the clinical case for proton beam therapy. Summary sentence Proton beam therapy is a technically advanced and promising form of radiation therapy.

    As coded clinical data are used in a variety of areas (e.g. health services funding, epidemiology, health sciences research), coding errors have the potential to produce far-reaching consequences. In this study the causes and consequences of miscoding were reviewed. In particular, the impact of miscoding due to inadequate medical documentation on hospital funding was examined. Appropriate reimbursement of hospital revenue in the casemix-based (output-based) funding system in the state of Victoria, Australia relies upon accurate, comprehensive, and timely clinical coding. In order to assess the reliability of these data in a Melbourne tertiary hospital, this study aimed to: (a) measure discrepancies in clinical code assignment; (b) identify resultant Diagnosis Related Group (DRG) changes; (c) identify revenue shifts associated with the DRG changes; (d) identify the underlying causes of coding error and DRG change; and (e) recommend strategies to address the aforementioned. An internal audit was conducted on 752 surgical inpatient discharges from the hospital within a six-month period. In a blind audit, each episode was re-coded. Comparisons were made between the original codes and the auditor-assigned codes, and coding errors were grouped and statistically analysed by categories. Changes in DRGs and weighted inlier-equivalent separations (WIES) were compared and analysed, and underlying factors were identified. Approximately 16% of the 752 cases audited reflected a DRG change, equating to a significant revenue increase of nearly AU$575,300. Fifty-six percent of DRG change cases were due to documentation issues. Incorrect selection or coding of the principal diagnosis accounted for a further 13% of the DRG changes, and missing additional diagnosis codes for 29%. The most significant of the factors underlying coding error and DRG change was poor quality of documentation. It was concluded that the auditing process plays a critical role in the identification of causes

    The purpose of this study was to evaluate the effectiveness of a treatment for patients with cervicogenic dizziness that consisted of therapeutic education and exercises. The Dizziness Handicap Inventory and Neck Disability Index were used. Secondary outcomes included range of motion, postural control, and psychological variables. Seven patients (two males and five females) aged 38.43±14.10 with cervicogenic dizziness were included. All the participants received eight treatment sessions. The treatment was performed twice a week during a four weeks period. Outcome measures included a questionnaire (demographic data, body chart, and questions about pain) and self-reported disability, pain, and psychological variables. Subjects were examined for cervical range of motion and postural control. All of these variables were assessed pre- and postintervention. Participants received eight sessions of therapeutic education patient and therapeutic exercise. The majority of participants showed an improvement in catastrophism (mean change, 11.57±7.13; 95% confidence interval [CI], 4.96–18.17; d=1.60), neck disability (mean change, 5.14±2.27.28; 95% CI, 3.04–7.24; d=1.32), and dizziness disability (mean change, 9.71±6.96; 95% CI, 3.26–16.15; d=1.01). Patients also showed improved range of motion in the right and left side. Therapeutic patient education in combination with therapeutic exercise was an effective treatment. Future research should investigate the efficacy of therapeutic patient education and exercise with larger sample sizes of patients with cervicogenic dizziness. PMID:27419118

To verify the relationship of ALDH2 rs671 G>A polymorphism and esophageal cancer (EC, we performed a meta-analysis of a total of 31 published data including 8,510 patients and 16,197 controls. Methods: The pooled odds ratio (OR and the 95% confidence interval (CI were calculated using a fixed or random-effects model. Heterogeneity (PH, publication bias, and sensitivity analysis were also determined. Results: Although a protective effort was found in the rs671 homozygote comparison (AA/GG: OR=0.69; 95% CI=0.48–0.98, the heterozygote comparison was apparently associated with the risk of EC, particularly in the Chinese population (AG/GG: OR=1.39; 95% CI=1.03–1.87. Alcohol consumption remarkably increased this risk, especially in the AG genotype. Drinking men with the AG genotype appeared to show a higher risk (AG/GG: OR=4.39; 95% CI=1.24–6.55 than drinking women. Conclusion: The present meta-analysis provided advanced information regarding the association of the ALDH2 A>G polymorphism and EC. Taken together, insights from this study suggested an enhanced effect on the development of EC through a genetic–environmental interaction.

    Objective To study the clinical and cytogenetic characteristics of four patients with myel odysplastic syndrome (MDS) and one with acute myeloid leukemia experiencing t(1; 7).Methods Five patients seen in our hospital from 1992 to 2001 were diagnosed as MDS and acute myelocytic leukemia (AML) according to the French-American-British (FAB) criteria. Chromosomes were prepared using the direct method as well as 24-hou r unstimulated cultures of fresh heparinized bone marrow for each subject, while R-banding was used to analyze karyotypes. Dual-color fluorescence in situ hy bridization (FISH) using SpectrumRed and SpectrumGreen directly labeled chromoso me 1-specific α-satellite DNA probe (red) and chromosome 7- specific α-sat ellite DNA probe (green) was performed for three cases. Results Of the five patients, three had 1;7 translocation due to along history of expos ure to benzene. In three cases, dual-color FISH resulted in three red signals and two green ones, in which one red signal adjoining one green signal in 27.6% , 84% and 18.5% metaphases, respectively. Conclusions Exposure to benzene may be the cause for Chinese MDS and AML patients with t(1;7 ) translocation. The result of dual-color FISH convincingly confirmed that the centromere of the derivative chromosome 7p/1q resulting from 1;7 translocation was made up of centromeres from both chromosomes 1 and 7.

    Mature T-cell lymphoid malignancies comprise a group of heterogeneous diseases that vary in clinicopathological features, biological behavior, treatment response, and prognosis. Bone marrow (BM) infiltration is more commonly present in mature T-cell lymphoid malignancies compared with their B-cell counterparts and hence important for differential diagnosis. In this study, clinical characteristics and prognostic factors were analyzed in 225 patients with mature T-cell lymphoid malignancies treated in a single institution. These included 29 cases of T-cell lymphoproliferative disorders (T-LPD, all with BM infiltration) and 196 cases of T-/natural-killer-cell lymphoma (T/NKCL, 56 with BM infiltration and 140 without BM infiltration). The estimated 5-year overall survival (OS) rates of T-LPD and T/NKCL were 96.6% and 37.3%, respectively. T-LPD patients were less likely to exhibit poor performance status, advanced disease stage, presence of B symptoms, or abnormal level of serum β-2 microglobulin. With similar pathological characteristics, T/NKCL patients with BM infiltration showed significantly lower response rates and shorter OS than those without BM infiltration (P = 0.0264 and P cell lymphoid malignancies.

  10. Clinical study on osteoradionecrosis of the jaws

    International Nuclear Information System (INIS)

    In the present study osteoradionecrosis which had developed after radiotherapy for malignant tumor was studied clinically and therapeutically and the following results were obtained. 1. The subjects were 28 patients with squamous cell carcinoma and 2 patients with adenoid cystic carcinoma aged 38 to 72. The ratio of male: female was 3.3 : 1. The time of manifestation was 1 month-14 years after irradiation. The main symptoms were pain and exposed bone mainly in the region of mandibular molar tooth. 2. Osteoradionecrosis was observed in 10 cases supposed to be induced by tooth extraction but also in 5 edentulous cases. 3. When the osteoradionecrosis cases were classified into limited area type and wide range type on the basis of clinical findings. X-ray of the jaws showed the presence of bone resorption and induration together in many wide range type cases. 4. Scintigram of bone showed widespread accumulation of radiation even in clinically limited area type, and the picture of some loss of bone and the intensity of the accumulation were considered to be extremely useful as an index in making therapeutical plans and decisions on the prognosis of tumor of the jaws. 5.

    In the present study osteoradionecrosis which had developed after radiotherapy for malignant tumor was studied clinically and therapeutically and the following results were obtained. 1. The subjects were 28 patients with squamous cell carcinoma and 2 patients with adenoid cystic carcinoma aged 38 to 72. The ratio of male: female was 3.3 : 1. The time of manifestation was 1 month-14 years after irradiation. The main symptoms were pain and exposed bone mainly in the region of mandibular molar tooth. 2. Osteoradionecrosis was observed in 10 cases supposed to be induced by tooth extraction but also in 5 edentulous cases. 3. When the osteoradionecrosis cases were classified into limited area type and wide range type on the basis of clinical findings. X-ray of the jaws showed the presence of bone resorption and induration together in many wide range type cases. 4. Scintigram of bone showed widespread accumulation of radiation even in clinically limited area type, and the picture of some loss of bone and the intensity of the accumulation were considered to be extremely useful as an index in making therapeutical plans and decisions on the prognosis of tumor of the jaws. 5. As the method of treatment, sequestrectomy was performed in 14 of 19 cases of the limited area type and 4 of 11 cases of the wide range type and excision of the jaws in 4 cases. 6. Hyperbaric oxygen therapy was carried out in 3 cases and had good effect. (J.P.N.).

    Full Text Available The objective of this article is to consider methodological and epistemological questions concerning the use of case study as a strategy of scientific research. Focusing on case selection through statistics analysis, the use of clinical files in research, and the construction of clinical theory, three kinds of case studies in the area of speech pathology are presented. Advantages, possibilities, difficulties, and necessary cares concerning the use of the strategy are analyzed. The results point out to the flexibility of the strategy in terms of selection of cases, collection, analysis, and interpretation of data, stressing its versatility. From clinical performance to theoretical construction and education, the transition of the strategy through different spheres of knowledge is evident, which emphasizes its role in the construction of knowledge.

    The authors present a severe case of polyostotic fibrous dysplasia in which there was considerable involvement of cranial bone and facial skeleton. Numerous lesions were present at the level of the long bones of limbs. Endocrine dysfunction was also present in the form of a hypophyseal adenoma secreting prolactin and ACTH. The concomitance of acromegaly or gigantism and/or hyperprolactinemia and polyostotic fibrous dysplasia has only been reported to date in a few cases in literature. The authors describe the appearance of the subject, correlating clinical photographs with X-rays. They report the clinical excursus of the patient characterised by the gradual increase in deformities which seriously jeopardized the patient's relational life, in particular the appearance of a bulk on the forehead and checks and the deformation of the symphyseal portion of the mandible with presence of interdental diastemata. The patient also complained diplopia, difficulty in chewing owing to the mobilisation of teeth, and increasing bone pain probably due to nerve compression by exuberant bone. It was not possible to perform corrective surgery owing to the patient's overall poor health conditions. In fact, dilatative cardiomyopathy which continued to worsen in spite of numerous forms of medical treatment resulted in the patient's death owing to cardiac decompensation. Even the attempt to treat the patient's primary endocrine dysfunction using bromocryptine and subsequently octreotide failed to produce positive results owing to the onset of collateral effects which led to the early suspension of treatment.

    Full Text Available Abstract Background The Organizational Readiness to Change Assessment (ORCA is a measure of organizational readiness for implementing practice change in healthcare settings that is organized based on the core elements and sub-elements of the Promoting Action on Research Implementation in Health Services (PARIHS framework. General support for the reliability and factor structure of the ORCA has been reported. However, no published study has examined the utility of the ORCA in a clinical setting. The purpose of the current study was to examine the relationship between baseline ORCA scores and implementation of hepatitis prevention services in substance use disorders (SUD clinics. Methods Nine clinic teams from Veterans Health Administration SUD clinics across the United States participated in a six-month training program to promote evidence-based practices for hepatitis prevention. A representative from each team completed the ORCA evidence and context subscales at baseline. Results Eight of nine clinics reported implementation of at least one new hepatitis prevention practice after completing the six-month training program. Clinic teams were categorized by level of implementation-high (n = 4 versus low (n = 5-based on how many hepatitis prevention practices were integrated into their clinics after completing the training program. High implementation teams had significantly higher scores on the patient experience and leadership culture subscales of the ORCA compared to low implementation teams. While not reaching significance in this small sample, high implementation clinics also had higher scores on the research, clinical experience, staff culture, leadership behavior, and measurement subscales as compared to low implementation clinics. Conclusions The results of this study suggest that the ORCA was able to measure differences in organizational factors at baseline between clinics that reported high and low implementation of practice

    2016-01-01

    This article discusses the clinical use of laser-microtextured abutments on dental implant restorations. Four cases are presented, each using one of the four commercially available laser-microtextured abutment styles. Numerous preclinical and clinical studies have shown the positive effects of laser microtexturing on the implant platform in limiting crestal bone loss and benefiting soft tissue stability. Other histologic studies of laser microtexturing on the implant abutment have demonstrated the ability of this specific feature to block epithelial downgrowth and provide a functional connective tissue attachment to the abutment surface. Other abutment designs, styles, and materials have only demonstrated a soft tissue seal with epithelial adhesion and a circular ring of connective tissue fibers around the abutment without direct contact. This article presents clinical and radiographic case examples from a private practice perspective on the longterm successful use of microtextured abutments with respect to crestal bone levels, exceptional soft tissue health, and stability with minimal sulcular depth.

    Full Text Available São feitas considerações clínicas e anátomo-patológicas sobre as mioclonias velopalatinas a propósito de um caso em que estas hipercinesias se estendiam também à faringe e ao diafragma (mioclonias velofaringodiafragmáticas. A paciente, de 82 anos de idde, foi internada com quadro caracte- rizado por torpor, paresia braquiofacial direita e afasia do tipo misto. Os familiares informavam que a paciente há aproximadamente 6 meses vinha apresentando dificuldade progressiva na marcha e na fala. Ao exame neurológico chamava a atenção a presença de mioclonias velofaringodiafragmáticas, rítmicas e de alta freqüência, que persistiam mesmo durante o sono e, ulteriormente, no estado de coma. Do ponto de vista anátomo-patológico ficou evidenciada a presença de lesões vasculares isquémicas acometendo ambos os núcleos denteados. Ao exame das olivas bulhares observou-se, bilateralmente, lesões neuronais múltiplas caracterizadas por hipertrofia dendrítica e vacuolizações irregulares. O comprometimento do complexo dento-olivar é salientado.A case of palatal myoclonus is reported and the clinical and neuropathological aspects are studied. The patient, a woman aged eighty two, during the clinical course of the disease showed stupor, right brachial monoplegia, aphasia, epileptic seizures and myoclonus involving the palate, pharynx and diaphragm (palatopharyngodiaphragmatic myoclonus. The movements were not influenced by sleep and remained during the coma. The post-mortem findings revealed generalized arteriosclerotic vascular changes with scattered areas of softening in the cortex, brain stem and cerebellum. The significance of a pathway directly linking the dentate nucleus of the cerebellum and the contralateral inferior olive (the dentato-olivary pathway is stressed.

    Objective: To analyze the characteristics of clinical symptoms, examinations, and treatments in patients with intracranial germinoma. Methods: Medical records of 33 cases with intracranial germinoma between January 2000 and January 2011 were retrospectively reviewed. Results: The study population consisted of 26 males and 7 females. Eighteen patients had a single tumor and 15 patients had multiple tumor. Twelve (36.4% ) were in the sellar region, 13 (39.4% ) in the pineal region, 5 cases (15.2% ) in basal ganglia and 9 cases in the periventricular region. Clinical manifestations: 21 patients (63.7% ) had headache, nausea and vomiting; 10 (30.3% ) had blurred vision and visual field damage; 11 (33.3% ) patients had diabetes insipidus and 7 patients (21.2% ) had limb weakness. Image study: MRI examination showed long T1, T2 or abnormal T1, T2 in MRI, which were enhanced equally by contrast medium. Diagnostic methods: 17 cases were confirmed by pathological diagnosis and 16 cases by diagnostic radiotherapy. Treatment: 3 cases underwent resection; 4 cases with obstructive hydrocephalus underwent ventriculoperitoneal shunt, and 10 patients underwent stereotactic surgery. All the patients underwent radiotherapy combined with chemotherapy. Symptoms were relieved obviously, but 2 patients had spinal cord metastasis. Conclusion: The increased intracranial pressure, polyuria, diplopia are the most common clinical symptoms of intracranial germ cell tumors. Common locations of lesions are the saddle area and pineal region. The whole brain + local radiotherapy combined with chemotherapy treatment is a common and effective modality for intracranial germinoma. Most patients have clinical symptoms remission and long survival. (authors)

    SUMMARY The osteonecrosis of the maxillares caused by bisphosphonates (OMB) either wrongly known or not reconised in earlier times became nowadays very important among the dentists and maxillo-facials surgeons because of the potential serious consequences that might bring in the oral cave of the patients, who are suffering already for their base condition. The goal of our work was to verify if a deep treatment and an attentive observation with a close follow-up can bring to the resolution of serious cases of ostenecrosis of the maxillares by bisphosphonantes. Although without a statistic value our case report put the basis for a chance to execute wider casistic studies. PMID:23285372

  6. Evaluation of Stream Mining Classifiers for Real-Time Clinical Decision Support System: A Case Study of Blood Glucose Prediction in Diabetes Therapy

    Directory of Open Access Journals (Sweden)

    Simon Fong

    2013-01-01

    Full Text Available Earlier on, a conceptual design on the real-time clinical decision support system (rt-CDSS with data stream mining was proposed and published. The new system is introduced that can analyze medical data streams and can make real-time prediction. This system is based on a stream mining algorithm called VFDT. The VFDT is extended with the capability of using pointers to allow the decision tree to remember the mapping relationship between leaf nodes and the history records. In this paper, which is a sequel to the rt-CDSS design, several popular machine learning algorithms are investigated for their suitability to be a candidate in the implementation of classifier at the rt-CDSS. A classifier essentially needs to accurately map the events inputted to the system into one of the several predefined classes of assessments, such that the rt-CDSS can follow up with the prescribed remedies being recommended to the clinicians. For a real-time system like rt-CDSS, the major technological challenges lie in the capability of the classifier to process, analyze and classify the dynamic input data, quickly and upmost reliably. An experimental comparison is conducted. This paper contributes to the insight of choosing and embedding a stream mining classifier into rt-CDSS with a case study of diabetes therapy.

    Full Text Available We describe a case with a false-negative PCR-based analysis for JC virus in cerebrospinal fluid (CSF in a patient with clinical and radiological findings suggestive of progressive multifocal leukoencephalopathy (PML who was on chronic immunosuppressive therapy for rheumatoid arthritis. Our patient developed rapidly progressive global decline with clinical and radiographic findings suggestive of PML, but JC virus PCR in CSF was negative. The patient passed away 3 months from the onset of her neurological symptoms. Autopsy confirmed the diagnosis of PML with presence of JC-polyoma virus by immunohistochemical staining. This case highlights the potential of false-negative JC virus PCR in CSF when radiographic and clinical features are suggestive of “possible PML.” We review the plausible causes of potential false-negative CSF results and suggest that when the clinical presentation is suspicious for PML repeat CSF analysis utilizing ultrasensitive PCR assay and subsequent brain biopsy should be considered if CSF remains negative. Additionally, appropriate exclusion of other neurologic conditions is essential.

  10. A clinical analysis of cases with stage IV laryngeal carcinoma

    International Nuclear Information System (INIS)

    Forty-four cases with stage IV laryngeal carcinoma treated in our department between 1991 and 2009 were clinically analyzed. The cases were equivalent to 16.8% of the total laryngeal cases, and 77.3% of the stage IV cases were of the supraglottic type. The disease-specific 5-year survival rate of all of the stage IV cases was 67.2%. Differences in the prognoses between under T3 and T4 were not statistically significant. Although the differences in the prognoses between surgical and nonsurgical treatment of the larynx were not statistically significant, neck dissection cases had a significantly better prognosis compared to cases without neck dissection. Neither radiotherapy nor chemotherapy had any influence on the prognosis. Therefore, positive treatment is needed even though the stage of the cases is advanced, and especially in cases with neck lymph node metastasis, neck dissection is strongly recommended. For histopathologically high-risk cases in which radiotherapy and chemotherapy were indicated in this study, appropriate additional treatment will be effective in order to prevent prognostic deterioration.

    Since the drop in the bed capacity of civil psychiatric hospitals, an increase in the bed capacity of forensic psychiatric care and prison units has been reported in the United States and Europe. However, in Canada, a decrease in the number of people with severe mental illness (SMI) during the last two decades in penitentiaries has been reported. At the same time, an increase in individuals found not criminally responsible on account of mental disorder (NCRMD) was observed in forensic hospitals. The aim of this study is to compare incarcerated severely mentally ill (I-SMI) individuals with forensic-hospitalized SMI individuals in terms of their clinical profiles and service use in the province of Quebec (Canada). A case-control study design was selected using a sample of 44 I-SMI individuals and 59 forensic-hospitalized SMI individuals. Important findings include the following: I-SMI persons had less schooling; they more often reported suicide attempts and violent and non-violent crimes; and they had a higher level of comorbidity involving Cluster B personality disorders and substance-use disorders. Forensic-hospitalized SMI persons were more likely to have been receiving psychiatric follow-up before hospitalization. The final logistic regression model showed that lifetime suicide attempts, non-violent crimes, and psychopathic traits were higher among I-SMI individuals than among forensic-hospitalized SMI individuals. In contrast, receiving regular psychiatric follow-up was associated with forensic-hospitalized SMI individuals. Differences in psychopathological characteristics and the use of mental health services were found for I-SMI persons. More research is needed to determine which new initiatives might be efficacious in addressing the mental health needs of I-SMI individuals.

    Pathogenic factors of Staphylococcus aureus (SA) in the development of infective endocarditis (IE) have not been sufficiently investigated. The purpose of this study was to analyze the pathogenesis and virulence factors of SA in patients with IE as compared to patients with uncomplicated bacteremia (un-BAC). This is a retrospective case-control study (2002-2014) performed at a tertiary hospital in Spain. Clinical and epidemiological factors were analyzed. We assessed the presence of toxin genes [toxic shock syndrome toxin 1 (tst-1) and enterotoxins A (etA), B (etB), and D (etD)] and the potential relationship between accessory gene regulator (agr) groups and the development of IE confirmed by polymerase chain reaction (PCR). Twenty-nine patients with IE were compared with 58 patients with uncomplicated S. aureus bacteremia (SAB). As many as 75.9 % of patients had community-acquired IE (p infection and severe sepsis or septic shock and IE. Also, a minimum inhibitory concentration (MIC) of vancomycin ≥1.5 μg/ml was found to be associated with IE. The agr group I was prevalent (55.2 % vs. 31.0 %; p = 0.030). No association was observed between toxin genes (tst-1, etA, etB, and etD) and IE. The superantigen (SAg) most frequently found in SA isolates was tst-1 (12.6 %). We found no association between toxin genes and IE, probably due to the small sample size. However, a direct relationship was found between agr I and the development of IE, which suggests that agr I strains may have more potential to cause IE. PMID:26951263

    The clinical course and outcome of hydrocephalus diagnosed in utero is not well understood. To approach this problem 40 cases were reviewed of intrauterine fetal hydrocephalus diagnosed with sonography, and follow-up information was obtained regarding them. Sonograms were evaluated for cerebral dimensions, biparietal diameter, brain mantle size, ventricular ratio, amount of amniotic fluid, and associated abnormalities. Neonatal brain sonograms and computed tomographic (CT) scans were reviewed also. Clinical charts were reviewed for maternal age and parity, referral source, family history, fetal age at diagnosis and delivery, mode of delivery, physical examination and/or autopsy findings, karyotype, amniotic alpha 1 fetoprotein level, cause of death, shunt placement after birth, and status of live infants. The observations indicate that the prognosis for fetal hydrocephalus is poor. Only six infants (15%) were alive after an average follow-up of 13 months. Three children were normal and the other three had neurologic abnormalities ranging from severe (paralysis and incontinence) to minimal (2-3 months delayed motor development). Thirty-four fetuses or neonates died. Nine families elected to terminate pregnancy. Ten opted for decompression at delivery for progressive hydrocephalus. Neural tube defects were present in 12 of 23 infants at delivery. Fourteen other infants had additional significant congenital abnormalities. Other abnormal sonographic findings included polyhydramnios (13 of 38), oligohydramnios or decreased fluid (nine of 38), neural tube defect (nine of 40), and other congenital abnormalities (nine of 40). These findings indicate that hydrocephalus diagnosed in utero by sonography is caused by a heterogeneous group of disorders. In general, the prognosis for normal development is poor. Individual prognoses, however, depend on the specific malformations and the interventions used. PMID:3883714

    Michael T M Wang

    Full Text Available BACKGROUND: Dietary supplement use is increasing despite lack of evidence of benefits, or evidence of harm. Press releases issued by the supplements industry might contribute to this situation by using 'spin' (strategies to hype or denigrate findings to distort the results of clinical studies. We assessed press releases issued in response to publication of clinical studies on dietary supplements. METHODS AND FINDINGS: We analyzed 47 supplements industry press releases and 91 non-industry press releases and news stories, generated in response to 46 clinical studies of dietary supplements published between 1/1/2005 and 5/31/2013. The primary outcome was 'spin' content and direction. We also assessed disposition towards use of dietary supplements, reporting of study information, and dissemination of industry press releases. More supplements industry press releases (100% contained 'spin' than non-industry media documents (55%, P90% of studies that reported no benefit, or harm, of the supplement. Industry press releases less frequently reported study outcomes, sample size, and estimates of effect size than non-industry media documents (all P<0.001, particularly for studies that reported no benefit of supplements. Industry press releases were referenced by 148 news stories on the websites of 6 organizations that inform manufacturers, retailers and consumers of supplements. CONCLUSIONS: Dietary supplements industry press releases issued in response to clinical research findings are characterized by 'spin' that hypes results that are favourable to supplement use and denigrates results that are not.

    Full Text Available Objectives. Organized hematoma (OH is a rare, nonneoplastic, hemorrhagic lesion causing mucosal swelling and bone thinning, mainly in the maxillary sinus. We aimed to clarify the clinical presentation and treatment of OH. Methods. Three cases of maxillary sinus OH and a literature review are presented. Results. Three men aged 16–40 years complained of nasal obstruction, frequent epistaxis, and/or headache. Clinical and radiological examinations revealed a maxillary sinus OH. They were cured in a piecemeal fashion via endoscopic middle meatal antrostomy. Furthermore, vascular endothelial growth factor and its receptor were expressed in the lesion. Conclusions. The pathogenesis of OH is unclear and it presents various histological and imaging findings; however, it is not difficult to rule out malignant tumors. Minimally invasive surgery such as endoscopic sinus surgery can cure it completely. Thus, it is important to determine the diagnosis using CT and MRI and to quickly provide surgical treatment.

    Full Text Available Background and Design: Sweet syndrome is an inflammatory disease characterized by the abrupt onset of pain, red papules and plaques, fever, neutrophilic leukocytosis, and dermal neutrophilic infiltrate. There are not enough data about Sweet syndrome in Turkey. In this article, we studied clinical, laboratory, histopathological, and epidemiological characteristics of patients, who presented to our clinic, and compared the findings with the literature. Materials and Methods: All patients diagnosed with Sweet syndrome in our clinic between 2005 and 2011 were included in the study. The epidemiological, clinical, and laboratory findings were retrospectively evaluated. Results: A total of 31 patients with Sweet’s syndrome - 24 female (77.4%, 7 male (22.6%; aged 23-82 years – included in the study. The average age of the patients was 48 years. Cutaneous lesions were most frequently localized in the upper extremity. Conjunctivitis was the common systemic manifestation, followed by fever, arthralgia, and myalgia. The most common trigger factor was infections of the upper respiratory tract. In histopathological evaluations of skin biopsies, dense neutrophil infiltration compatible with Sweet syndrome was detected in the dermis. Also, findings of vasculitis were determined in 3 patients. Discussion: The clinical and laboratory findings in our study are mostly similar to those reported in the literature. We found evidence of vasculitis in 10% of cases, therefore, we think the presence of vasculitis does not necessarily rule out the diagnosis of Sweet syndrome

    Full Text Available Background: Crescentic glomerulonephritis (CrGN, defined as crescents involving more than 50% of the glomeruli, includes pauci-immune, immune complex-mediated and anti-glomerular basement membrane disease. Objectives: The present study was aimed at evaluating the various clinical, biochemical and histological parameters in CrGN with respect to these categories and clinical outcome. Materials and Methods: Renal biopsies diagnosed as CrGN between Jan 2008 and Feb 2010 were included. Clinical and laboratory parameters were retrieved along with the therapeutic approach and clinical outcome, wherever available. Renal biopsy slides were evaluated for various glomerular, tubulo-interstitial and arteriolar features. Appropriate statistical tests were applied for significance. Results: A total of 46 cases of CrGN were included; majority (71.7% of cases were pauci-immune (PI while 28.3% were immune complex-mediated (IC. Among clinical features, gender ratio was significantly different between PI and IC groups (P = 0.006. The various histological parameters, including proportion of cellular crescents, tuft necrosis and Bowman′s capsule rupture, were similar in both the groups. Four unusual associations, including idiopathic membranoproliferative glomerulonephritis (MPGN, multibacillary leprosy, acute lymphoblastic leukemia and C1q nephropathy were detected. Adequate follow-up information was available in 21 (46% of the patients. Of these, 11 (52.4% were dialysis-dependent at the last follow-up. Adult patients required renal replacement therapy more frequently than pediatric cases (P = 0.05. Presence of arteriolar fibrinoid necrosis also showed association with poor clinical outcome (P = 0.05. Conclusions: Crescentic glomerulonephritis remains one of the main causes of acute renal failure with histological diagnosis. Immunohistologic examination is essential for accurate classification into one of the three categories. This condition should be considered

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

    2005-05-01

    Background: There has been much debate concerning the most suitable protocol for parathyroid scintigraphy; the merits of various radiopharmaceuticals versus the correct imaging protocol to visualise both ectopic and anatomically placed adenomas against the various equipment choices have been debated. Aim: To demonstrate, through the use of a case study, the necessity of changing imaging protocols for parathyroid scintigraphy where a definitive imaging diagnosis is absent in the face of strong clinical suspicion. Method: Use is made of Tc99mMIBI, full field chest scintigraphy, a clearly defined imaging protocol and SPECT imaging to locate ectopic parathyroid tissue in a female patient with significant symptoms of parathyroid hyperfunction. Results: A single hyperfunctioning adenoma is located in the pre-carinal area of the mediastinum. Using a radioguided surgical technique the hyperfunctioning tissue is excised and confirmed by histopathology. Conclusion: Whilst a dramatic reduction in patient symptoms was not seen immediately in this patient, the symptoms of the illness have been subsiding since January 2003. This case study demonstrates the necessity of changing imaging protocols for parathyroid scintigraphy where a definitive imaging diagnosis is absent in the face of strong clinical suspicion.

    We studied the relationship between outcome and clinical symptoms or CT findings of 34 cases with primary pontine hemorrhage diagnosed by CT scan from April 1994 to March 1999. This series comprised 19 males and 15 females ranging in age from 45 to 89 years with a mean of 67.1 years. According to their outcome at discharge, the cases were divided into 6 groups. Sixteen cases died within 2 weeks after onset (group AD), 4 cases died with complication in the chronic phase (group D), 3 cases were severely disabled to bed-ridden state (group C), 2 cases recovered to a daily life with wheelchair (group B), 4 cases recovered to a daily life with partial assistance (group A), and 5 cases showed a full recovery (group J). The factors significantly correlated with bed outcome are as follows: young age, consciousness disturbance, respiratory disturbance, tachycardia over 90 beats per minute, hyperthermia over 39 deg C, abnormal pupils, loss of oculocephalic reflex, tetraplegia, decerebrate rigidity, bilateral extension or over 30 mm transverse diameter of the hematoma.

    Recently, development and research of nutraceuticals based on marine collagen peptides (MCPs) have been growing due to their high homology with human collagens, safety, bioavailability through gut, and numerous bioactivities. The major concern regarding safety of MCPs intake relates to increased risk of oxidative stress connected with collagen synthesis (likewise in fibrosis) and to ROS production by MCPs-stimulated phagocytes. In this clinical-laboratory study, fish skin MCPs combined with p...

    Full Text Available Abstract Background We previously reported that measuring circulating serum mRNAs using quantitative one-step real-time RT-PCR was clinically useful for detecting malignancies and determining prognosis. The aim of our study was to find crucial serum mRNA biomarkers in esophageal cancer that would provide prognostic information for post-esophagectomy patients in the critical care setting. Methods We measured serum mRNA levels of 11 inflammatory-related genes in 27 post-esophagectomy patients admitted to the intensive care unit (ICU. We tracked these levels chronologically, perioperatively and postoperatively, until the two-week mark, investigating their clinical and prognostic significance as compared with clinical parameters. Furthermore, we investigated whether gene expression can accurately predict clinical outcome and prognosis. Results Circulating mRNAs in postoperative esophagectomy patients had gene-specific expression profiles that varied with the clinical phase of their treatment. Multivariate regression analysis showed that upregulation of IL-6, VWF and TGF-β1 mRNA in the intraoperative phase (p = 0.016, 0.0021 and 0.009 and NAMPT and MUC1 mRNA on postoperative day 3 (p ®, Ono Pharmaceutical Co., Ltd. significantly correlated with MUC1 and NAMPT mRNA expression (p = 0.048 and 0.045. IL-6 mRNA correlated with hypercytokinemia and recovery from hypercytokinemia (sensitivity 80.9% and was a significant biomarker in predicting the onset of severe inflammatory diseases. Conclusion Chronological tracking of postoperative mRNA levels of inflammatory-related genes in esophageal cancer patients may facilitate early institution of pharamacologic therapy, prediction of treatment response, and prognostication during ICU management in the perioperative period.

    Clinical Data Warehouses (CDW) can complement current Clinical Information Systems (CIS) with functions that are not easily implemented by traditional operational database systems. Here, we describe the design and deployment strategy used at the Pompidou University Hospital in southwest Paris. Four realms are described: technological realm, data realm, restitution realm, and administration realm. The corresponding UML use cases and the mapping rules from the shared integrated electronic health records to the five axes of the i2b2 CDW star model are presented. Priority is given to the anonymization and security principles used for the 1.2 million patient records currently stored in the CDW. Exploitation of a CDW by clinicians and investigators can facilitate clinical research, quality evaluations and outcome studies. These indirect benefits are among the reasons for the continuous use of an integrated CIS.

    A sporadic outbreak of an unknown disease occurred among dairy cattle, from early February to late May 1955, in Japan. The characteristic symptoms of this disease were dyspnea and depilation; out of 29 cases, 8 died while 2 were slaughtered. Clinical studies have disclosed that the symptoms were similar to those found in cases of mercury poisoning as described by others. So the animals' feed was suspected of being the cause of the sickness. It was confirmed that the incident was due to poisoning resulting from ingestion of linseed meal treated with a mercurial fungicide. From the results of the testing anamnesis, it was found that 171 cattle were fed with the meal and 29 cases were affected. In veiw of the wide use of mercurial preparations for treating seed grains against fungi infection, a further experimental study was made on the effects of the feed and fungicide upon calves.

    Objective: To study the characteristics and clinical features of uterine neoplasms developed after radiation ther-apy for cervical carcinoma. Methods: Clinical data of 47 cases of uterine neoplasms occurred following radiation therapy for cervical carcinoma were retrospectively reviewed. Results: The median age at uterine neoplasms diagnosis was 62 years (range: 38-77 years), and the median latency period from initial therapy to development of uterine neoplasms was 14 years (range: 5-35 years). Thirty of 47 cases were endometrial carcinoma, of which 3 were uterine papillary serous carcinoma (UPSC). Seventeen of 47 patients were uterine sarcoma, all of those were carcinosarcoma. The distribution by stage, grade, and histology of 30 cases of endometrial carcinoma was as follows: stage Ib, 1 case; stage Ic, 2 cases; stage Ⅱ, 6; stage Ilia, 4; stage Ⅲb, 2; stage Ⅲc, 11; stage Ⅳ, 4 cases; grade 1, two cases; grade 2, nine; grade 3 (include 3 UPSC patients), seventeen; unknown grade, two; endometried, 27; UPSC, 3 cases; 7 of 30 cases of endometrial carcinoma had recurrences (23.3%), at median time to recurrence was 24 months, and their median survival time was 26 months. The overall 3- and 5-year survival rates were 60% and 38%, respectively. Of the 17 cases of uterine sarcoma, the median survival was 10 months, 6 patients oc-curred recurrence (35.9%), at a median time to recurrence was 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rates were 12% and 0, respectively. Conclusion: The main uterine neoplasms development after radiation therapy for cervical carcinoma is endomethal carcinomas, of which there is a preponderance of high-risk histological subtypes and a poor prognosis. Most of the uterine sarcomas occurred following radiation therapy for cervical carcinoma are carcinosarcomas and the prognosis is very poor.

    OBJECT Adrenocorticotropic hormone (ACTH) adenomas have been recognized as a more aggressive and invasive subtype of pituitary adenomas. An additional and clinically relevant peculiarity of these tumors is their ability to modify their clinical expression from a silent form to Cushing disease or vice versa. The aim of this study was to review a series of patients with pituitary adenomas and analyze the clinical implications of the transformation of clinical expression in 5 cases that showed this phenomenon. METHODS The authors retrospectively reviewed a series of patients with pituitary adenoma and collected clinical, biohumoral, and neuroradiological data of those who presented with a transformation from silent ACTH adenomas to functioning tumors or vice versa. In all the cases, preoperative assessment consisted of brain MRI, ophthalmological examination, and complete baseline endocrinological investigation. In patients with clinical and/or biochemical findings suspicious for Cushing syndrome, a low-dose dexamethasone suppression test was performed to rule in or out this diagnosis. Endocrinological evaluations were repeated 1 month after surgery, 3 months after surgery, and every 6 months or annually thereafter. Ophthalmological evaluations and brain MRIs were repeated after 3 months and then every 6 or 12 months thereafter. RESULTS Five patients (2 men and 3 women) included in this series had corticotropic tumors that showed transformation from an endocrinologically silent form to manifest Cushing disease and vice versa. The mean age at presentation was 40 years (range 18-51 years). In 3 of these patients, a transformation from silent to functioning ACTH adenoma with manifest Cushing disease occurred. In 1 patient, the authors observed the transition from a functioning to a silent adenoma with spontaneous resolution of hypercortisolism. Another patient's silent adenoma "shifted" to a functioning adenoma and then regressed back to a silent form with spontaneous

  19. Running a postmortem service - a business case and clinical experience

    International Nuclear Information System (INIS)

    The purpose of the postmortem examination is to offer answers to explain the cause and manner of death. In the case of perinatal, infant and paediatric postmortem examinations, the goal is to identify unsuspected associated features, to describe pathogenic mechanisms and new conditions, and to evaluate the clinical management and diagnosis. Additionally, the postmortem examination is useful to counsel families regarding the probability of recurrence in future pregnancies and to inform family planning. Worldwide the rate of paediatric autopsy examinations has significantly declined during the last few decades. Religious objections to postmortem dissection and organ retention scandals in the United Kingdom provided some of the impetus for a search for non-invasive alternatives to the traditional autopsy; however, until recently, imaging studies remained an adjunct to, rather than a replacement for, the traditional autopsy. In 2012, Sheffield Children's Hospital National Health Service Foundation Trust set up the service provision of minimally invasive fetal, perinatal and neonatal autopsy, while a postmortem imaging service has been running in Melbourne, Australia, since 2008. Here we summarise the essentials of a business case and practical British and Australian experiences in terms of the pathological and radiologic aspects of setting up a minimally invasive clinical service in the United Kingdom and of developing a clinical postmortem imaging service as a complementary tool to the traditional autopsy in Australia.

    2015-01-01

    Background: Several studies have highlighted the implications of impulsivity and novelty seeking for both the maintenance and the process of recovery from bulimia nervosa (BN). Cognitive behavioral therapy (CBT) is the treatment of choice for BN, but for some cases, this treatment alone might not be sufficient for reducing the high levels of impulsivity. The paper presents a case report of a patient with BN, examining the effectiveness of using a videogame (VG; Playmancer) as an additional intervention designed to address impulsivity. Design: Psychometric and neuropsychological measures were collected at baseline. After this assessment, Playmancer was applied prior to CBT, following an “A-B-A-C-A” single case experimental design. Impulsivity levels were assessed with the Conner’s Continuous Performance Test II (CPT-II). After the Playmancer treatment, the patient started CBT, and the levels of impulsivity were recorded again. Finally, psychometric and neuropsychological measures were collected after treatment. Weekly frequency of binges and vomiting were also recorded during the entire procedure. Results: After the VG intervention, psychometric measures such as anxiety levels, impulsivity and novelty seeking decreased. Regarding the neuropsychological measures, impulsivity levels (measured with the CPT-II) progressively decreased throughout the intervention, and an improvement in decision making capacities was observed. Furthermore, the frequency of binges also decreased during and after the VG intervention. Discussion: This case report suggests that using the Playmancer VG to reduce impulsivity prior to CBT may enhance the final results of the treatment for BN. PMID:26236261

    Data authenticity is the basic requirement of clinical studies. In actual clinical conditions how to establish formatted case report forms (CRF) in line with the requirement for data authenticity is the key to ensure clinical data quality. On the basis of the characteristics of clinical data in actual clinical conditions, we determined elements for establishing formatted case report forms by comparing differences in data characteristics of CRFs in traditional clinical studies and in actual clinical conditions, and then generated formatted case report forms in line with the requirement for data authenticity in actual clinical conditions. The data of formatted CRFs generated in this study could not only meet the requirement for data authenticity of clinical studies in actual clinical conditions, but also comply with data management practices for clinical studies, thus it is deemed as a progress in technical methods.

    García-Delaney, Cristina; Sánchez-Garcés, Maria-Ángeles; Sánchez-Torres, Alba; Gay-Escoda, Cosme

    2015-01-01

    Background Interleukin-1 (IL-1) is a proinflammatory cytokine that plays an important role in the pathogenesis of periodontitis, and so it might be useful to detect high-risk cases of peri-implantitis. It has been reported that IL-1 polymorphisms and smoking habit have a synergic effect, increasing the incidence of peri-implantitis. The aim of the present study was to evaluate the relationship between IL-1 gene polymorphisms and peri-implantitis in smoking patients. Material and Methods A case-control study was performed in 27 patients with peri-implantitis and 27 patients with healthy implants. All patients included were smokers. IL-1A-C889T, IL-1B+C3953T and IL-1RN+T2018C were identified by polymerase chain reaction (PCR) amplification in order to establish a relation between these variables and the presence of peri-implantitis. A bivariate analysis was performed and odds-ratio (OR) were calculated. Results The incidence of peri-implantitis was significantly higher in patients with previous history of periodontitis (p=0.024; OR=10.9). Both groups were similar regarding IL-1A-C889T, IL-1B+C3953T and IL-1RN+T2018C genotypes. No increased risk in heavy smokers with IL-1 polymorphism was found. Conclusions IL-1 genotypes do not seem to be good predictors of peri-implantitis in the great majority of smoking patients. Furthermore, no synergic effect was found between IL-1 genotypes and heavy smokers. Patients with a previous history of periodontitis were more prone to peri-implantitis. Key words:Peri-implantitis, interleukin-1 genotype positive, case-control study, smoking. PMID:26449434

  20. 331 cases of clinically node-negative supraglottic carcinoma of the larynx: a study of a modest size fixed field radiotherapy approach

    International Nuclear Information System (INIS)

    Purpose: For node-negative supraglottic carcinoma of the larynx, radiotherapy with surgery in reserve commonly provides very good results in terms of both local control and survival, while preserving function. However uncertainty exists over the treatment of the node-negative neck. Elective whole neck radiotherapy, while effective, may be associated with significant morbidity. The purpose of this study was to examine our practice of treating a modest size, fixed field to a high biologically effective dose and compare it with the patterns of recurrence from other centers that use different dose/volume approaches. Methods and Materials: Over a 10-year period 331 patients with node-negative supraglottic carcinoma of the larynx were treated with radiotherapy at the Christie Hospital Manchester. Patients were treated with doses of 50-55 Gy in 16 fractions over 3 weeks. Data were collected retrospectively for local and regional control, survival, and morbidity. Results: Overall local control, after surgical salvage in 17 cases, was 79% (T1-92%, T2-81%, T3-67%, T4-73%). Overall regional lymph node control, after surgical salvage in 13 cases, was 84% (T1-91%, T2-88%, T3-81%, T4-72%). Five-year crude survival was 50%, but after correcting for intercurrent deaths was 70% (T1-83%, T2-78%, T3-53%, T4-61%). Serious morbidity requiring surgery was seen in 7 cases (2.1%) and was related to prescribed dose (50 Gy-0%, 52.5 Gy-1.3%, 55 Gy-3.4%). Discussion: Our results confirm that treating a modest size, fixed field to a high biologically effective dose is highly effective. It enables preservation of the larynx in most cases, with acceptable regional control and no loss of survival compared to whole neck radiotherapy regimes

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

    Objective To summarize the clinical characteristics of caesarean scar pregnancy and to investigate its treatment.Methods Clinical case records of 45 cases of caesarean scar pregnancy from June 2003 to September 2007 were reviewed.The characteristics and management of cases were analyzed.Results The women's average age was 32.8±5.1 years.All cases had amenorrhoea.and 27 cases had vaginal bleeding from spotting to morderate.Seven cases were misdiagnosed as normal early intrauterine pregnancy or inevitable miscarriage before dilation and curettage(D & C).In case of massive bleeding,caesarean scar pregnancy was diagnosed after D & C.Bleeding was controlled and uterus was conserved in 6 cases,and 1 case underwent hysterectomy because of uncontrollable bleeding.The remaining 38 cases had ultrasound scan,which indicated scar pregnancy before primary treatment.Eight cases were primarily treated with dilation and curettage,in which only 2 cases had slight bleeding in the operation and no further treatment.Nineteen cases were primarily treated with dilation and curettage after uterine artery embolization.in which 17 cases needed no further treatment and had no complications.The success rate was 89.4%(17/19).Eleven cases were primarity treated with trichosanthin 1.2 mg intramuscular.No one encountered massive bleeding,but 7 cases of these 11 cases needed extra treatment.Conclusion Caesarean scar pregnancy must be cautious of,especially in cases of inevitable miscarriage.Dilation and curettage followed uterine artery embolization can be used as the primary treatment for caesarean scar pregnancy.

  15. Clinical observation of submandibular gland transfer for the prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma: a prospective randomized controlled study of 32 cases

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the clinical efficacy of submandibular gland transfer for the prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma. Using the randomized controlled clinical research method, 65 patients with nasopharyngeal carcinoma were randomly divided into an experimental group consisting of 32 patients and a control group consisting of 33 patients. The submandibular glands were averted to the submental region in 32 patients with nasopharyngeal carcinoma before they received conventional radiotherapy; a lead block was used to shield the submental region during therapy. Prior to radiotherapy, the function of the submandibular glands was assessed using imaging. Submandibular gland function was measured using 99mTc radionuclide scanning at 60 months after radiotherapy. The data in the questionnaire regarding the degree of xerostomia were investigated and saliva secretion was measured at 3, 6, 12, and 60 months after radiotherapy. In addition, the 5-year survival rate was calculated. After follow-up for 3, 6, and 12 months, the incidence of moderate to severe xerostomia was significantly lower in the experimental group than in the control group. The average amount of saliva produced by the experimental and control groups was 1.60 g and 0.68 g, respectively (P < 0.001). After follow-up for 60 months, the uptake and secretion functions of the submandibular glands in the experimental group were found to be significantly higher than in the control group (P < 0.001 and P < 0.001, respectively). The incidence of moderate or severe xerostomia was significantly lower than in the control group (15.4% and 76.9%, respectively; P < 0.001). The 5-year survival rates of the experimental group and the control group were 81.3% and 78.8%, respectively, and there was no significant difference between the two groups (P = 0.806).

    Full Text Available The sporadic or chronic use of drugs and alcohol is directly related to conduct disorders and to the triggering of psychopathological states of sub-acute or chronic course. The excessive consumption of alcohol and excessive traffic/consumption of illicit drugs by individuals without mental illness or disability are actions of free will; they are therefore criminally responsible for their behaviour, even if they commit a crime during the state of intoxication, which the individual chose voluntarily to experience. In clinical practice, it is widely accepted that the treatment of these disorders is only effective when the patient accepts it voluntarily and that involuntary commitment (compulsive treatment is only carried out when the psychopathological state associated justifies the presuppositions of Article 12 of the Mental Health Law. However, if the compulsive treatment is of a penal character, mandated by a judge, the individual is obligated to accept treatment, independent of whether or not he suffers from mental illness. The authors present two case studies, one of drug addiction, the other of alcoholism, and discuss the clinical and judicial perspectives on the treatment of these clinical entities.

    Full Text Available Objective  To review the experiences of diagnosis and treatment of pneumatosis cystoides intestinalis (PCI, and study the clinical characteristics of the disease in order to improve the diagnosis and treatment. Methods  Clinical data from 20 patients with endoscopically confirmed PCI were retrospectively analyzed. They were admitted to the Chinese PLA General Hospital from June 1995 to June 2015. Results  Among the patients 16 of them were male,and the other four were female. The main clinical manifestations were abdominal distention, diarrhea, abdominal pain and mucous bloody stool. The diagnosis relied mainly on colonoscopy and pathological examination. Laparoscopy assisted colorectal cancer resection was performed in 1 patient, laparostomy and repair of sigmoid colon perforation in 1, endoscopic treatment in 5 cases, drug administration and hyperbaric oxygen therapy in 2, drug treatment alone in 7, and no treatment in 4. Conclusions  The final diagnosis depends on endoscopic findings. No treatment is recommended to patients with no symptoms. The management of patients with PCI includes antibiotics, oxygen therapy, endoscopic therapy, surgery, and appropriate therapy related to the underlying cause of PCI. The prognosis is good.

    Tomizawa, M; Otsuka, Y; Noda, T

    2005-01-01

    Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric Dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. Recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.

    Primary care practitioners are frequently unprepared to take into account the effects of social determinants on underprivileged patients' health and health management. To address this issue among dental professionals, an original onsite continuing education (CE) course on poverty was co-developed by researchers, dental professionals, and community organizations. Integrating patient narratives and a short film, course material aims to elicit critical reflection and provide coaching for practice improvements. A qualitative case study conducted with a large Montreal Canada dental team reveals CE course participants' newfound understandings and increased sensitivity to the causes of poverty and the nature of life on welfare. Participants also describe revised interpretations of certain patient behaviors, subtle changes in communication with patients and improved equity in appointment-giving policy. Unintended outcomes include reinforced judgment and a tendency to moralize certain patient categories. Implications for health professional educators, researchers, and dental regulatory authorities are discussed. PMID:27524746

  3. Clinical utility of LC3 and p62 immunohistochemistry in diagnosis of drug-induced autophagic vacuolar myopathies: a case-control study.

    Directory of Open Access Journals (Sweden)

    Han S Lee

    Full Text Available BACKGROUND: Some patients treated with chloroquine, hydroxychloroquine, or colchicine develop autophagic vacuolar myopathy, the diagnosis of which currently requires electron microscopy. The goal of the current study was to develop an immunohistochemical diagnostic marker for this pathologic entity. METHODOLOGY: Microtubule-associated protein light chain 3 (LC3 has emerged as a robust marker of autophagosomes. LC3 binds p62/SQSTM1, an adapter protein that is selectively degraded via autophagy. In this study, we evaluated the utility of immunohistochemical stains for LC3 and p62 as diagnostic markers of drug-induced autophagic vacuolar myopathy. The staining was performed on archival muscle biopsy material, with subject assignment to normal control, drug-treated control, and autophagic myopathy groups based on history of drug use and morphologic criteria. PRINCIPAL FINDINGS: In all drug-treated subjects, but not in normal controls, LC3 and p62 showed punctate staining characteristic of autophagosome buildup. In the autophagic myopathy subjects, puncta were coarser and tended to coalesce into linear structures aligned with the longitudinal axis of the fiber, often in the vicinity of vacuoles. The percentage of LC3- and p62-positive fibers was significantly higher in the autophagic myopathy group compared to either the normal control (p<0.001 or the drug-treated control group (p<0.05. With the diagnostic threshold set between 8% and 15% positive fibers (depending on the desired level of sensitivity and specificity, immunohistochemical staining for either LC3 or p62 could be used to identify subjects with autophagic vacuolar myopathy within the drug-treated subject group (p ≤ 0.001. SIGNIFICANCE: Immunohistochemistry for LC3 and p62 can facilitate tissue-based diagnosis of drug-induced autophagic vacuolar myopathies. By limiting the need for electron microscopy (a time consuming and costly technique with high specificity, but low sensitivity

    International Nuclear Information System (INIS)

    In this study 14 cases of internuclear ophthalmoplegia (INO) were analysed. The correlation of clinical symptoms with localization of the responsible lesions was studied in these patients. The subjects included 9 patients with CVD, 2 with MS, 1 with Fisher's syndrome, 1 with cranial polyneuritis and one with unknown etiology. Nine patients with unilateral INO are all associated with brainstem infarction. The other 5 patients including 2 MS had bilateral INO. CT showed abnormal findings in brain stem in 7 out of 14 patients. As for MRI an abnormality was found in 5 out of the 8 patients examined. Two of the 7 patients without any abnormality on CT had abnormal signals on MRI. We divided INO into 3 groups based on the clinical symptoms: 1) anterior type in which convergence was involved concomitantly with adduction paralysis, 2) typical type in which dissociated nystagmus was more marked in the abducting eye, and convergence was preserved, 3) posterior type in which abduction is impaired without adduction disturbance. There were 5 cases of anterior type, 9 of typical type, and none of posterior type. On MRI two patients of anterior type had abnormalities in the dorsal midbrain, and one patient had an abnormality in the pons, and two patients of typical type had abnormalities in the upper or middle dorsal pons to the dorsal midbrain. CT failed to demontrate any responsible lesions in 2 patients in whom the responsible legions were clearly identified on MRI. (J.P.N.)

    2008-03-01

    Full Text Available Abstract Background In view of rapidly increasing prescription costs, case-mix adjustment should be considered for effective control of costs. We have estimated the variability in pharmacy costs explained by ACG in centers using patient electronic records, profiled centers and physicians and analyzed the correlation between cost and quality of prescription. Methods We analyzed 65,630 patient records attending five primary care centers in Spain during 2005. Variables explored were age, gender, registered diagnosed episodes of care during 2005, total cost of prescriptions, physician and center. One ACG was assigned to each patient with ACG case-mix software version 7.1. In a two-part model, logistic regression was used to explain the incurrence of drug expenditure at the first stage and a linear mixed model that considered the multilevel structure of data modeled the cost, conditional upon incurring any expense. Risk and efficiency indexes in pharmacy cost adjusted for ACG were obtained for centers and physicians. Spearman rank correlation between physician expenditure, adjusted for ACG, and a prescription quality index was also obtained. Pediatric and adult data were analyzed separately. Results No prescription was recorded for 13% of adults and 39.6% of children. The proportion of variance of the incurrence of expenditure explained by ACGs was 0.29 in adults and 0.21 in children. For adults with prescriptions, the variance of cost explained by ACGs was 35.4%, by physician-center was 1.8% and age 10.5% (residual 52.3%. For children, ACGs explained 22.4% of cost and physician-center 10.9% (residual 66.7%. Center efficiency index for adults ranged 0.58 to 1.22 and for children 0.32 to 2.36. Spearman correlation between expenditure and prescription quality index was -0.36 in family physicians (p = 0.019, N = 41 and -0.52 in pediatricians (p = 0.08, N = 12. Conclusion In our setting, ACG is the variable studied that explains more variability in

    Full Text Available Abstract Background Cancer diseases and their therapies have negative effects on the quality of life. The aim of this study is to assess the effectiveness of case management in a sample of oncological outpatients with the intent of rehabilitation after cancer treatment. Case management wants to support the complex information needs of the patients in addition to the segmented structure of the health care system. Emphasis is put on support for self-management in order to enhance health - conscious behaviour, learning to deal with the burden of the illness and providing the opportunity for regular contacts with care providers. We present a study protocol to investigate the efficacy of a case management in patients following oncology rehabilitation after cancer treatment. Methods The trial is a multicentre, two-arm randomised controlled study. Patients are randomised parallel in either 'usual care' plus case management or 'usual care' alone. Patients with all types of cancer can be included in the study, if they have completed the therapy with chemo- and/or radiotherapy/surgery with curative intention and are expected to have a survival time >1 year. To determine the health-related quality of life the general questionnaire FACT G is used. The direct correlation between self-management and perceived self-efficacy is measured with the Jerusalem & Schwarzer questionnaire. Patients satisfaction with the care received is measured using the Patient Assessment of Chronic Illness Care 5 As (PACIC-5A. Data are collected at the beginning of the trial and after 3, 6 and 12 months. The power analysis revealed a sample size of 102 patients. The recruitment of the centres began in 2009. The inclusion of patients began in May 2010. Discussion Case management has proved to be effective regarding quality of life of patients with chronic diseases. When it comes to oncology, case management is mainly used in cancer treatment, but it is not yet common in the

    2016-04-01

    Full Text Available BACKGROUND The duodenal injury can pose a formidable challenge to the surgeon and failure to manage it properly may have devastating results. Over the centuries, there was little to offer the patient of acute abdomen beyond cupping, purgation and enemas, all of which did more harm than good. It was not until 1884 that Mikulicz made an attempt to repair a perforation. Recent statistics indicate roughly 10% of population develop gastric or duodenal ulcer in life time. Roughly 1-3% of population above the age of 20 years have some degree of peptic ulcer activity during any annual period. A detailed history with regards to the signs and symptoms of the patient, a meticulous examination, radiological and biochemical investigations help to arrive at a correct preoperative diagnosis. In this study, a sincere effort has been put to understand the demographic patterns, to understand the underlying aetiology and to understand the effectiveness of the standard methods of investigation and treatment in use today. METHODS This is a 24 months prospective study i.e., from September 2011 to September 2013 carried out at Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation. The study included the patients presenting to Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation to emergency ward with signs and symptoms of hollow viscus perforation. The sample size included 30 cases of duodenal perforation. RESULTS Duodenal ulcer perforation commonly occurs in the age group of 30-60 years, but it can occur in any age group. Majority of the patients were male. Smoking and alcohol consumption were risk factors in most cases (53.3% for the causation of duodenal ulcer perforation. Sudden onset of abdominal pain, situated at epigastrium and right hypochondrium was a constant symptom (100%. Vomiting, constipation and fever were not so common.

    Full Text Available Guidelines and clinical practice vary considerably with respect to thrombosis prophylaxis during plaster cast immobilization of the lower extremity. Identifying patients at high risk for the development of venous thromboembolism (VTE would provide a basis for considering individual thromboprophylaxis use and planning treatment studies. The aims of this study were (1 to investigate the predictive value of genetic and environmental risk factors, levels of coagulation factors, and other biomarkers for the occurrence of VTE after cast immobilization of the lower extremity and (2 to develop a clinical prediction tool for the prediction of VTE in plaster cast patients.We used data from a large population-based case-control study (MEGA study, 4,446 cases with VTE, 6,118 controls without designed to identify risk factors for a first VTE. Cases were recruited from six anticoagulation clinics in the Netherlands between 1999 and 2004; controls were their partners or individuals identified via random digit dialing. Identification of predictor variables to be included in the model was based on reported associations in the literature or on a relative risk (odds ratio > 1.2 and p ≤ 0.25 in the univariate analysis of all participants. Using multivariate logistic regression, a full prediction model was created. In addition to the full model (all variables, a restricted model (minimum number of predictors with a maximum predictive value and a clinical model (environmental risk factors only, no blood draw or assays required were created. To determine the discriminatory power in patients with cast immobilization (n = 230, the area under the curve (AUC was calculated by means of a receiver operating characteristic. Validation was performed in two other case-control studies of the etiology of VTE: (1 the THE-VTE study, a two-center, population-based case-control study (conducted in Leiden, the Netherlands, and Cambridge, United Kingdom with 784 cases and 523

    Full Text Available BACKGROUND Empyema thoracis is a disease that despite centuries of study still causes significant morbidity and mortality. AIMS To study the age-sex profile, clinical presentation, etiologic agents, management and the overall treatment outcome of empyema thoracis in children. METHODOLOGY A total of 25 patients of both the sexes aged 0-12 years diagnosed to have empyema thoracis and who underwent tube thoracostomy from March 2013 to February 2014 were studied. Detailed clinical history, physical examination, relevant routine and specific investigation were done. The pleural fluid was studied for gram staining, microscopy, cytology, pleural fluid culture and antibiotic sensitive pattern. All the patients were treated with tube thoracostomy and antibiotic therapy depending on the culture and sensitivity pattern. Complications were recorded. RESULTS Majority of patients (0.64% were seen in age group of 1-5 years. Fever (96%, breathlessness (92%, and cough (72% were the commonest presenting features. Bacteriological examination revealed staphylococcus aureus as the commonest etiologic agent (20% isolated from pleural fluid culture. Pyopneumothorax (16% was the commonest complication seen in these patients. All patients (92% were treated with antibiotics, and drainage of the empyema was effected by closed thoracostomy in (92% of the cases. There was no mortality. CONCLUSION Empyema is not rare in our practice. Early diagnosis and proper treatment of pneumonia prevent the development of empyema. Antibiotics and tube thoracostomy is an effective method of treating pyogenic empyema thoracis in children in resource poor settings.

    The objective of this study was to determine whether the occurrence of a previous case of pathogen-specific clinical mastitis (CM) protects Holstein dairy cows against a recurrent case. Pathogens studied were Escherichia coli, Staphylococcus aureus, Staphylococcus spp., Streptococcus spp., Klebsiella spp., and Trueperella pyogenes. A total of 40 864 lactations (17,265 primiparous and 23,599 multiparous) from 19 835 cows from 5 large, high milk producing New York State dairy herds were analysed. We estimated the effects of parity, calving diseases, milk yield, current season and number of CM cases in the previous lactation on the risk of a first CM case using generalised linear mixed models with a log link and Poisson error distribution. The aforementioned risk factors and the occurrence of previous cases of pathogen-specific CM within the current lactation were evaluated as risks for second and third cases of pathogen-specific CM. Cows with more CM cases in the previous lactation were at greater risk of pathogen-specific CM in the current lactation. Multiparous cows were at greater risk of a second CM case if they had suffered from a first CM case that was caused by the same pathogen as the second case. In contrast, a second CM case generally put cows at greater risk of a third case, irrespective of whether the third case was caused by the same or a different pathogen. Our results showed that a previous case of pathogen specific CM does not generally protect against a recurrent case.

    Dissing Sørensen, Pernille; Løkke Nielsen, Ann-Kristina

    Case studies may have different research goals. One such goal is the testing of small-scale and middle-range theories. Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus...... on the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications for research...... design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes in a progressive...

    1989-11-01

    Mucoceles are commonly occurring lesions of the oral mucous membrane and the most common lesion involving minor salivary tissue. The incidence of mucoceles is understandable since accessary salivary gland tissue is widely distributed throughout the oral mucous membrane and trauma to the mucosa, which causes their formation, occurs frequently. But only a few studies have been reported that describe its detailed features. This is a retrospective study on the salivary mucoceles in the oral mucous membrane and based on clinical chart, biopsy request and photomicroscopic finding of 112 patients treated by Dept. of Oral Surgery in Seoul National University Hospital, during the period of last 10 years. The results were as following. 1. The age range of the 112 patients was 2 to 60 years, with a peak incidence in the second decade and a gradual decline thereafter. Of the 112 patients, 49 (44%) were males and 63 (56%) were females, the male-to-female ratio being 1:1.29. 2. The majority of these lesions were located on the lower lip but occurred with lesser frequently on the buccal mucosa, floor of the mouth, tongue, retromolar region, upper lip. 3. Of the 112 patients, 107 (95%) were treated by excision and only 5 were treated by marsupialization. 18 of 112 cases had recurrence and the recurrence rate in this study was 16%. 4. Only 3 of the 112 cases revealed an epithelial lining. This incidence indicates that the mucus-extravasation by the damage of excretory duct rather than the ductal dilatation by mucus-retention may play a critical role in the production of these lesions. 5. In 81 cases (72.3%) minor salivary gland were included in the excision biopsy, specimen. Changes observed in the glandular tissue were atrophy and infiltration of chronic inflammatory cell, but the secretory function of gland was thought to be normal in most cases because the changes were mild.

  3. Long-time follow-up study of localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma and the clinical features of antibiotic-resistant cases of gastric MALT lymphoma

    International Nuclear Information System (INIS)

    To clarify the clinical features of gastric mucosa-associated lymphoid tissue (MALT) lymphoma (GML) with persistent lymphoma after eradication therapy of Helicobacter pylori (H. pylori), and the outcome of long-time follow-up study after treatment against GML, seventy-six patients with localized GML were studied. The median follow-up period was 44.4 months. Thirty-eight of 49 patients (77.6%) with H. pylori-positive GML had been cured of GML by antibiotic therapy alone. On the other hand, none of 13 patients with H. pylori-negative GML had been cured by antibiotic therapy (77.6% vs 0%, p<0.001). ''H. pylori-negative'' is one of the clinical features of antibiotic-resistant cases with GML. There was no significant difference in sex, age, stage, endoscopic finding, depth, and affected region between the two groups of cured and persistent GML with H. pylori infection. Twenty-two of 29 patients (75.6%) with antibiotic-resistant or H. pylori-negative cases of GML had been cured by 30 Gy radiation therapy. Low-dose radiation was thought to be a useful therapeutic procedure as a second line treatment'' of localized GML. (author)

    Full Text Available Abstract Background The accuracy of malaria case reporting is challenging due to restricted human and material resources in many countries. The reporting often depends on the clinical diagnosis because of the scarcity of microscopic examinations. Particularly, clinical malaria case reporting by primary health care facilities (local clinics, which constitutes the baseline data of surveillance, has never previously been sufficiently evaluated. In order to improve the malaria reporting system to the level required to eventually eliminate this disease, this study estimates the gaps between the records of clinics and government statistics regarding the incidence of clinical malaria, and then also examines some factors that might explain the data discrepancy, including such variables as clinic staffing and record keeping. Methods All medical records for outpatients in 2007, handwritten by nurses, were collected from local clinics in Honiara, the capital of the Solomon Islands. The all-monthly clinical malaria cases were then recalculated. The corresponding monthly data in official statistics were provided by the government. Next, in order to estimate any data discrepancy, the ratio of the cases recorded at clinics to the cases reported to the government was determined on the monthly basis. Finally, the associations between the monthly discrepancy and other variables were evaluated by a multiple regression analysis. Results The mean data discrepancy between the records of clinics and government statistics was 21.2% (n = 96. Significant associations were observed between the discrepancy and the average number of patients (coefficient: 0.05, 95%CI: 0.31, 0.07, illegible handwriting (coefficient: 0.09, 95%CI: 0.04, 0.15, the use of tally sheets (coefficient:-0.38, 95%CI: -0.54, -0.22, and the clinic level (coefficient:-0.48, 95%CI:-0.89,-0.06.

    2014-01-01

    Depressive personality disorder (DPD) is highly studied and common in clinical settings. Nevertheless, it is rife with controversies and often overshadowed by major depression and dysthymia with which it shares many similarities but also is clinically distinct. Possibly as a result, DPD is underdiagnosed and misunderstood in clinical care. Thus the goal of this practice review is to present a case from psychiatric clinical work illustrating how DPD may be commonly overlooked in routine care, and how the conceptualization of this case and its treatment plan changed course once DPD was considered by treating staff, ultimately contributing to the successful outcome of the case. Questions elicited by the case are subsequently discussed in the context of the empirical literature on DPD, allowing for a clearer picture to emerge on DPD and its role in the development, course, and treatment of depression.

    Recently, National agencies in charge of the development of clinical practice guidelines (CPGs) have started to improve the usual narrative CPGs to provide guidance for different clinical pathways. In France, in conjunction with the development of the type 2 diabetes National CPGs, we have developed the system RecosDoc-Diabète which allows to interactively build a patient-centred pathway and get the appropriate recommendations. National narrative CPGs and RecosDoc-Diabète were published and made available online at the same time (February 2013). A questionnaire was provided to collect visitors' judgement about the system. Between February 12th and December 31st, 2013, 55,203 visitors accessed the narrative CPGs whereas 10,565 accessed the system. Among them, 186 (2%) responded to the questionnaire. One third of the comments were criticisms towards the CPG content. The system was globally positively evaluated although assessments were mixed illustrating that users' needs may be contradictory.

    This paper describes the implementation of a clinical guideline across three acute Trusts. A Clinical Effectiveness Steering Group identified prevention of venous thromboembolism as a health priority. A local guideline development group adapted the recommendations of an existing review and produced a local guideline. Then, a multidisciplinary implementation group developed the practical aspects of implementing guidelines into routine daily practice. They identified appropriate staff to carry out risk assessment and to administer appropriate prophylaxis, as necessary. They also produced a "guideline pack" containing a training resource manual and implementation aids. Following this a multiple strategy implementation programme was used to introduce the guidelines, and an evaluation was carried out eight to ten months after the introduction of the guidelines. The evaluation identified a number of areas for improving current practice. Guideline implementation is a complex, time-consuming process.

    2013-12-01

    The apolitical legitimacy of "evidence-based medicine" offers a practical means for ethnography and critical social-science-and-humanities-of-health theory to transfer survival resources to structurally vulnerable populations and to engage policy and services audiences with urgent political problems imposed on the urban poor in the United States that harm health: most notably, homelessness, hyperincarceration, social service cut-backs and the War on Drugs. We present four examples of collaborations between ethnography and clinical research projects that demonstrate the potentials and limits of promoting institutional reform, political debate and action through distinct strategies of cross-methodological dialog with epidemiological and clinical services research. Ethnographic methods alone, however, are simply a technocratic add-on. They must be informed by critical theory to contribute effectively and transformatively to applied health initiatives. Ironically, technocratic, neoliberal logics of cost-effectiveness can sometimes render radical service and policy reform initiatives institutionally credible, fundable and capable of generating wider political support, even though the rhetoric of economic efficacy is a double-edged sword. To extend the impact of ethnography and interdisciplinary theories of political-economic, cultural and disciplinary power relations into applied clinical and public health research, anthropologists - and their fellow travelers - have to be able to strategically, but respectfully learn to see through the positivist logics of clinical services research as well as epidemiological epistemology in order to help clinicians achieve - and extend - their applied priorities. In retrospect, these four very differently-structured collaborations suggest the potential for "good-enough" humble scientific and political strategies to work for, and with, structurally vulnerable populations in a punitive neoliberal era of rising social inequality

    Tooth bleaching is a widespread dental treatment with important psychosocial antecedents and outcomes involved. In the activation of in-office bleaching agents, a selective light radiation, that is, a diode laser seems to be a positive choice to decrease the time of bleaching without surface modification and with no residual tooth sensitivity for maximum effect and minimal clinical and psychological side effects.

    We report the clinical outcome and prognostic factors in 39 cases of childhood Japanese Encephalitis admitted to a tertiary hospital of Upper Assam and followed up for 421 days in the community. The mortality rate was 20.5% in our study. The mean GCS (9.97 +/- 0.91) was higher in surviving cases than the fatal cases (GCS 7.5 +/- 1.78) at admission. The fatal cases died within 4.75 +/- 3.19 days in the hospital. All the patients had low BMI (surviving cases 13.54 +/- 2.3; fatal cases 12.05 +/- 0.12) and were anemic. Cerebrospinal fluid (CSF) was clear in 91.4% cases but pressure and protein content were increased in all cases. About 10% cases had parkinsonian features at the time of discharge. Residual symptoms remained in about one third of cases even after 421 days. PMID:12522277

    We are reporting over 500 acupuncture cases, a wide range of illnesses ranging from orthopedic, internal, neurological and psychological diseases, all of which were treated with a newly developed and therefore available Laserneedle system. This system was highly successful in treatment of a variety of illnesses including HWS, BWS and LWS Syndromes, gonarthritis, coxarthritis, rhizarthrosis, periarthritis of the shoulder, epicondylitis humeri radiails, tendinitis, fibromyalgia and PCP, Morbus Bechterew, paralysis after stroke, migraine and other headache syndrome, tinnitus, trigeminal neuralgia, gastropathy, bronchial asthma, AVK, mental depression and other psychovegatative burnout syndrome by using both body acupoints and otopoints. Treatment was made by simultaneously using 8Laserneedles which were not pricked into, but stuck onto the skin. The Laserneedles emit red and infrared Laserrays with a high energy output, so that perceptible, vegetative stimulation can be detected at the acupunctrured sites. We found out, that especially in the therapy resistant, long standing cases and cases with chronic back and spine problems, considerable improvements in easing pain and increasing mobility could be made. Recognizable success was made by using Laserneedles in cases suffering from psychological illnesses, especially psychosomatic related Burnoutsyndrome and cases of exhaustion. Usually after 2~ 3 treatments, efficient success was made, without any side effects what so ever.

    2000-01-01

    In our department two cases of Buschke-Löwenstein tumor were up to day observed. The first case, a man 51 years old, showed a big exophytic growth all over the glans, plus some similar lesions all along the shaft of the penis, besides a bilateral inguinal lymphoadenopathy. The second case was that of a man 70 years old, presenting a single exophytic growth on the glans. Both cases underwent a surgical excision of the lesions. The first patient had a local relapse after one year and a second one after further four months, which were both surgically exsected. Today, both patients are disease-free, being elapsed twelve years and sixteen months respectively. Surgical excision seems therefore to answer well the clinical problem, as for as the rarity of distant spread, the feasibility of conservative removal or reiteration, should it the case, are concerned.

    Background Malignant hyperthermia (MH), manifesting as MH crisis during and/or after general anesthesia, is a potentially fatal disorder in response to volatile anesthetics and depolarizing muscle relaxants.Though typical features of MH episode can provide clues for clinical diagnosis, MH susceptibility is confirmed by in vitro caffeine-halothane contracture test (CHCT) in western countries.It is traditionally thought that MH has less incidence and fewer typical characteristics in Chinese population than their western counterparts because of the different genetic background.In this study, we investigated the clinical features of MH in Chinese cases and applied the clinical grading scale and CHCT for diagnosis of MH.Methods A cluster of three patients with MH, from January 2005 to December 2007, were included in the study.Common clinical presentations and the results of some lab examinations were reported in detail.The method of the clinical grading scale of diagnosis of MH was applied to estimate the qualitative likelihood of MH and predict MH susceptibility.Muscle fibers of femoral quadriceps of the patients were collected and CHCT was performed to confirm the diagnosis of MH.Results The clinical grading scales of diagnosis of the disease for these cases were all ranked grade D6, suggesting almost diagnosed ones.And the results of caffeine test were positive correspondingly, indicating that the patients should be diagnosed as MH susceptibility (MHS) according to diagnostic criteria of the North America MH group, which were already confirmed by clinical presentations and biochemical results.Conclusions These Chinese cases manifest as MH crisis.The clinical grading scale of diagnosis of MH may provide clues for clinical diagnosis.CHCT can also be used in confirming diagnosis of MH in Chinese cases though they have different genetic background from their western counterparts.

    Multiple cases with various types of pediatric malabsorption syndromes were evaluated. The clinical manifestations, laboratory findings, pathophysiology, and histopathological descriptions of each patient were analyzed in an effort to clear the pathogenesis of the malabsorption syndromes and the treatments were undertaken. The cases studied, included one patient with cystic fibrosis, two with lactose intolerance with lactosuria (Durand type), one with primary intestinal lymphangiectasia, two with familial hypobetalipoproteinemia, one with Hartnup disease, one with congenital chroride diarrhea, one with acrodermatitis enteropathica, one with intestinal nodular lymphoid hyperplasia (NLH), five with intractable diarrhea of early infancy and four with glycogenosis type Ia. Each case description and outcome is described below: 1. A 15-year-old Japanese boy with cystic fibrosis presented with severe symptoms, including pancreatic insufficiency, bronchiectasis, pneumothorax and hemoptysis. His prognosis was poor. Analysis of the CFTR genes of this patient revealed a homozygous large deletion from intron 16 to 17b. 2. In the sibling case of Durand type lactose intolerance, the subjects'disaccaridase activity of the small bowel, including lactase, were within normal limits. The results of per oral and per intraduodenal lactose tolerance tests confirmed lactosuria in both. These observations suggested, not only an abnormal gastric condition, but also duodenal and intestinal mucosal abnormal permeability of lactose. 3. In the case of primary intestinal lymphangiectasia, the subject had a lymphedematous right arm and hand, a grossly coarsened mucosal pattern of the upper gastrointestinal tract (identified via radiologic examination) and the presence of lymphangiectasia (confirmed via duodenal mucosal biopsy). The major laboratory findings were hypoalbuminemia, decreased immunoglobulin levels and lymphopenia resulting from loss of lymph fluid and protein into the gastro

    BACKGROUND: Spinal muscular atrophy (SMA) is a kind of degenerative disease of nervous system. There are 4 types in clinic, especially types Ⅰ, Ⅱ and Ⅲ are common, and the researches on those 3 types are relative mature. Type Ⅳ is a kind of adult spinal muscular atrophy (ASMA), which has low incidence rate and is often misdiagnosed as amyotrophic lateral sclerosis, muscular dystrophy, cervical syndrome, or others.OBJECTIVE: To observe the clinical features of 46 ASMA patients and analyze the relationship between course and activity of daily living.DESIGN: Case analysis.SETTING: Departments of Neurology of the 81 Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 46 ASMA patients were selected from the Departments of Neurology of the 81Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA between April 1998 and January 2002. All patients were consentient. Among 46 cases, there were 37 males and 9 females with the mean age of 42 years. The patients' courses in all ranged from 6 months to 23 years, concretely, courses of 37 cases were less than or equal to 5 years, and those of 9 cases were more than or equal to 6 years.METHODS : ① All the 46 ASMA patients were asked to check blood sedimentation, anti O, serum creatinine,creatine, blood creatine phosphokinase (CPK) and muscular biopsy as early as possible. ② X-ray was used to measure plain film of cervical vertebra borderline film of cranium and neck at proximal end of upper limb of 25 cases and plain film of abdominal vertebra at proximal end of lower limb of 17 cases.③ Cerebrospinal fluid of lumbar puncture was checked on 42 cases, for routine examination, biochemical examination, and immunoglobulin examination.

    1988-12-01

    In the past six years, we have had experience with 40 patients with hypertensive thalamic hemorrhages, as verified by CT scan at our hospital within 24 hours. These patients were classified into the following three groups according to the location of the bleeding point and the size of the hematoma: (1) anteromedial (4 cases), (2) posterolateral (16 cases), and (3) massive (20 cases). The (1) and (2) hematomas were small (less than 3 cm in diameter), while those in (3) were large (more than 3 cm in diameter). Twenty cases (50% of all the thalamic hematomas) were small hematomas. The characteristic clinical symptoms of the anteromedial type were a mild disturbance of consciousness and thalamic dementia, while those of the posterolateral type were motor and sensory disturbance, and thalamic aphasia, respectively. Twenty cases (50%) were large hematomas. The clinical symptoms of these cases were mainly consciousness disturbance; 7 of them expired. Based on this experience, it may be considered that the patients whose hematoma size was larger than 3 cm had a poor prognosis and that the patients with the posterolateral type had a poor functional diagnosis.

    Full Text Available Whipple's disease (WD is a rare systemic disease of infectious etiology which involves the small intestine but can virtually affect any organ. We present here five cases (four males and one female ranging in age from 20 to 59 years. All patients had intestinal involvement associated or not with clinical manifestations linked to this organ. Vegetation in the tricuspid valve was observed in one patient, suggesting endocarditis caused by Tropheryma whippelii, with disappearance of the echocardiographic alterations after treatment. In one of the male patients the initial clinical manifestation was serologically negative spondylitis, with no diarrhea occurring at any time during follow-up. Ocular involvement associated with intestinal malabsorption and significant weight loss were observed in one case. In the other two cases, diarrhea was the major clinical manifestation. All patients were diagnosed by histological examination of the jejunal mucosa and, when indicated, of extraintestinal tissues by light and electron microscopy. After antibiotic treatment, full remission of symptoms occurred in all cases. A control examination of the intestinal mucosa performed after twelve months of treatment with sulfamethoxazole-trimethoprim revealed the disappearance of T. whippelii in four patients. The remaining patient was lost to follow-up.

Patient N., 75 years old, suffering for 15 years from Parkinson,s disease, akinetic­rigid form of the disease, stage 4 by Hyun–Yar. Since 2009, he received levodopa/carbidopa 250/25 mg 5 times/day (daily dose of 1250 mg of levodopa; pramipexole 3.5 mg per day (daily dose 3.5 mg, amantadine sulfate 100 mg 5 times/day (daily dose 500 mg. While taking antiparkinsonian drugs the patient developed behavioral disorders such as dopamine disregulatory syndrome combined with punding, hypersexuality and compulsive shopping accompanied by visual hallucinations. The total equivalent dose of levodopa was 1600 mg per day. The second clinical case. Patient R., 52 years old, suffers from Parkinson,s disease about 5 years, a mixed form. She complained of slowness of movement, tremor in her left hand, sleep disturbances, poor mood. The clinic was appointed piribedil 50 mg 3 times per day. Despite the fact that the patient took only one of dopaminergic drugs in a therapeutic daily dose, she developed impulsive­compulsive disorder as hyper­ sexuality, compulsive shopping and binge eating. Results. In the first clinical case for correction of behavioral disorders in patients with Parkinson,s disease levodopa/carbidopa dose was reduced to 750 mg per day (3/4 Tab. 4 times a day; added to levodopa/benserazide dispersible 100 mg morning and levodopa/benserazide 100 mg before sleep (total dose of levodopa of 950 mg per day. Amantadine sulfate and pramipexole were canceled. It was added to the therapy of atypical neuroleptic clozapine dose 6,25 mg overnight. After 3 months marked improvement, regressed visual hallucina­ tions, improved family relationships, background mood became more stable.

It is clinically characterized by fragile, brittle, coarse and lusterless hairs, due to uneven light reflection on the twisted hair surface. Pili torti may be associated with neurological abnormalities and ectodermal dysplasias. There is no specific treatment for this condition, but it may improve spontaneously after puberty. We report a case of pili torti in a child who presented fragile, brittle, difficult to comb hair. The patient had no comorbidities. PMID:26312667

    Sometimes, in order to properly restore teeth, surgical intervention in the form of a crown-lengthening procedure is required. Crown lengthening is a periodontal resective procedure, aimed at removing supporting periodontal structures to gain sound tooth structure above the alveolar crest level. Periodontal health is of paramount importance for all teeth, both sound and restored. For the restorative dentist to utilize crown lengthening, it is important to understand the concept of biologic width, indications, techniques and other principles. This article reviews these basic concepts of clinical crown lengthening and presents four clinical cases utilizing crown lengthening as an integral part of treatments, to restore teeth and their surrounding tissues to health.
