Correlation analysis of Trial of Org 10172 in acute stroke treatment classification and National Institutes of Health Stroke Scale score in acute cerebral infarction with risk factors

SUMMARY OBJECTIVE: The aim of this study was to investigate the correlation between the Trial of Org 10172 in acute stroke treatment classification and the National Institutes of Health Stroke Scale score of acute cerebral infarction as well as acute cerebral infarction's risk factors. METHODS: The clinical data of 3,996 patients with acute cerebral infarction hospitalized in Hebei Renqiu Kangjixintu Hospital from January 2014 to November 2018 were analyzed retrospectively. According to Trial of Org 10172 in acute stroke treatment, they were divided into five groups: arteriosclerosis, cardio cerebral embolism, arterial occlusion, other causes, and unknown causes. Through questionnaire design, routine physical examination, and physical and chemical analysis of fasting venous blood samples, the risk factors were evaluated, and the correlation between Trial of Org 10172 in acute stroke treatment classification and National Institutes of Health Stroke Scale classification was analyzed using multivariate logistic regression. In addition, the relationship between National Institutes of Health Stroke Scale score and risk factors in different groups was compared, and the correlation between Trial of Org 10172 in acute stroke treatment classification and National Institutes of Health Stroke Scale score was analyzed. RESULTS: Multivariate logistic regression analysis showed that diabetes, atrial fibrillation or stroke history, age, and education level were related to Trial of Org 10172 in acute stroke treatment classification. In the National Institutes of Health Stroke Scale comparison, the scores of the cardio cerebral embolism group were significantly higher than those of the other four groups, and patients with diabetes, atrial fibrillation, or stroke history had a high share, especially atrial fibrillation (33.06%). CONCLUSIONS: The nerve function defect is more serious after acute cerebral infarction with cardiogenic cerebral embolism, indicating a poor prognosis.

Is there any association between National Institute of Health category IV prostatitis and prostate-specific antigen levels in patients with low-risk localized prostate cancer?

ABSTRACT Purpose We investigated the association between National Institute of Health category IV prostatitis and prostate-specific antigen levels in patients with low-risk localized prostate cancer. Materials and Methods The data of 440 patients who had undergone prostate biopsies due to high PSA levels and suspicious digital rectal examination findings were reviewed retrospectively. The patients were divided into two groups based on the presence of accompanying NIH IV prostatitis. The exclusion criteria were as follows: Gleason score>6, PSA level>20ng/mL, >2 positive cores, >50% cancerous tissue per biopsy, urinary tract infection, urological interventions at least 1 week previously (cystoscopy, urethral catheterization, or similar procedure), history of prostate biopsy, and history of androgen or 5-alpha reductase use. All patient's age, total PSA and free PSA levels, ratio of free to total PSA, PSA density and prostate volume were recorded. Results In total, 101 patients were included in the study. Histopathological examination revealed only PCa in 78 (77.2%) patients and PCa+NIH IV prostatitis in 23 (22.7%) patients. The median total PSA level was 7.4 (3.5–20.0) ng/mL in the PCa+NIH IV prostatitis group and 6.5 (0.6–20.0) ng/mL in the PCa group (p=0.67). The PSA level was≤10ng/mL in 60 (76.9%) patients in the PCa group and in 16 (69.6%) patients in the PCa+NIH IV prostatitis group (p=0.32). Conclusions Our study showed no statistically significant difference in PSA levels between patients with and without NIH IV prostatitis accompanying PCa.

The Einstein-Brazil Fogarty: A decade of synergy

Abstract A rich, collaborative program funded by the US NIH Fogarty program in 2004 has provided for a decade of remarkable opportunities for scientific advancement through the training of Brazilian undergraduate, graduate and postdoctoral students from the Federal University and Oswaldo Cruz Foundation systems at Albert Einstein College of Medicine. The focus of the program has been on the development of trainees in the broad field of Infectious Diseases, with a particular focus on diseases of importance to the Brazilian population. Talented trainees from various regions in Brazil came to Einstein to learn techniques and study fungal, parasitic and bacterial pathogens. In total, 43 trainees enthusiastically participated in the program. In addition to laboratory work, these students took a variety of courses at Einstein, presented their results at local, national and international meetings, and productively published their findings. This program has led to a remarkable synergy of scientific discovery for the participants during a time of rapid acceleration of the scientific growth in Brazil. This collaboration between Brazilian and US scientists has benefitted both countries and serves as a model for future training programs between these countries.

The objective of this study was to determine the incidence of the National Institutes of Health (NIH) diagnostic criteria in children with Neurofibromatosis type 1 (NF1) in our setting, to compare them with the published statistical data, ophthalmological findings, the importance of complementary studies, and to establish follow-up criteria. Methods: We conducted a retrospective study including 245 patients that were admitted to the Pediatric Hospital Garrahan between 1988 and 2010. NF1 was diagnosed at the first multidisciplinary visit, using the NIH criteria. Neuroimaging and visual evoked potentials (VEP) were performed in some of the children. Results: 92% of the patients had café au laity spots; 40.8% neurofibromas; 75.5% Lisch nodules; 38.8% ephelides; 16.3% optic-nerve glioma; and 16.3% skeletal dysplasia. The disorder was hereditary in 49%. For each hypermetry,1.76 myopias were observed. Conclusions: These rates found were according to previous reports, except for ephelides, which were less common. Elective magnetic resonance imaging (MRI ) was performed, even in asymptomatic patients, and was repeated biannually and ophthalmological examination was done every six months until nine years of age. Currently, we do not indicate VEP

Histopathologic diagnosis of chronic graft-versus-host disease of the oral mucosa according to the National Institutes of Health Consensus / Diagnóstico histopatológico da doença do enxerto contra hospedeiro crônica da mucosa oral conforme Consenso do National Institutes of Health

Objective To validate the minimal criteria of the histopathologic diagnosis of oral chronic graft-versus-host disease, based on the histopathologic classification of the National Institutes of Health and correlate them with clinical features. Methods Forty-one specimens containing both oral mucosa and salivary glands were analyzed in slides stained with hematoxylin-eosin. The histological specimens were blindly examined by two trained pathologists using criteria recommended for the histopathologic diagnosis of chronic graft-versus-host disease proposed by the National Institutes of Health Consensus. The clinical classification of chronic graft-versus-host disease was correlated with analysis of slides. Results: Our data showed that the epithelium was involved in 39/41 specimens, presenting acanthosis (29/70.7%), exocytosis of lymphocytes (29/70.7%), thickening of basal lamina (29/70.7%), and apoptosis (15/36.6%). Connective tissue presented interstitial inflammatory infiltrate (38/92.7%). Minor salivary glands showed periductal fibrosis (38/92.7%), mixed periductal inflammatory infiltrate (32/78%), ductal ectasia (30/73.2%), lymphocytes around and into acinar units (30/73.2%), and interstitial fibrosis (29/70.7%). The most common clinical manifestations were lichenoid aspect (40/97.6%), complaints of sensitivity to oral feeding (38/92.7%), and dry mouth sensation (36/87.8%). Conclusion This study validated the National Institutes of Health Consensus of minimal histologic criteria for diagnosis of oral chronic graft-versus-host disease and has not found an association between the severity of clinical manifestation and the histopathological stage. .

Cultural Adaptation of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) - to Brazilian Spoken Portuguese: NIH-CPSI (Braz)

Objectives To create a Brazilian version of the National Institutes of Health – Chronic Prostatitis Symptom Index (NIH-CPSI) using a cross-cultural adaptation process. Materials and Methods The nine items of the NIH-CPSI were translated to Portuguese, by two independent translators, of native Portuguese language origin, and it was obtained a single version, that was retranslated to English by two English native spoken translators, in order to correct any discrepancies. Those versions were compared to the original text, the modifications were applied and it was created a final version in Portuguese. That was pre-tested and applied to 30 patients with pain or perineal or ejaculatory disorder. To each item of the pre-final version it was assigned a score according to the grade of understanding and clarity in order to implement the adequate corrections. The final version in Portuguese was submitted to evaluations including face validation and psychometric proprieties of reproducibility and internal consistency, respectively evaluated by the (p) Pearson correlation coefficient and α Cronbach coefficient. Results All items applied to 30 patients during pre-test phase had a grade higher than 8 of understanding and clarity, and were considered clearly understandable by the patients. However, at face validation evaluation, there was an inconsistency of item three that was redone. The final produced version, called NIH-CPSI (Braz) showed good reproducibility (p = 0.89-0.99) and internal consistency (α Cronbach coefficient = 0.85-0.93). Conclusions NIH-CPSI was adapted to Brazilian spoken Portuguese and its original proprieties were maintained, being a valid instrument for evaluations of symptoms of chronic prostatitis in Brazilian patients. .

Manejo agudo del infarto cerebral / Acute management of cerebral infarction

Las estrategias terapéuticas contra el infarto cerebral agudo están encaminadas, por una parte, a restaurar el flujo sanguíneo cerebral (FSC) y, por otra, a modificar las alteraciones bioquímicas que ocurren en la cascada isquémica (neuroprotección) con el fin de reducir el volumen del tejido cerebral dañado. Trombólisis intravenosa La trombólisis se basa en el reconocimiento de que la mayoría de los eventos isquémicos cerebrales se deben a la oclusión arterial cerebral. Administrada por vía intravenosa es posible reestablecer el FSC, aunque su uso se asocia con un elevado riesgo de hemorragia cerebral. En los últimos cinco años se reportaron cinco ensayos clínicos controlados en los que se utilizaron diferentes trombolíticos. Los estudios realizados con estreptokinasa fueron suspendidos prematuramente por la elevada frecuencia de complicaciones hemorrágicas, por lo que su uso está proscrito en EVC. Por otra parte, en 1996 la Food and Drug Administration, con base en un estudio realizado en los Institutos Nacionales de Salud de los Estados Unidos, aprobó el uso del activador tisular del plasminógeno humano (rtPA) para su uso en las primeras horas de un infarto cerebral. A continuación se resumen los aspectos más importantes de éste y el resto de los estudios relacionados con el tema.

Papanicolaou: Il est pase de mode, n'est-ce pa? / Papanicolaou: outmoded, isn't it?

the quality of cytopathology services in the United States has recently come under public scrutiny. While numerous studies have demonstrated remarkable success of the PAPANICOLAOU test in the reduction of cervical cancer, problems that include inadequacies in obtaining the sample, processing the sample screening and interpretation based on the PAPANICOLAOU Classification have been questioned. The recommendations of expert consultants attending a workhop sponsored by the Division of Cancer Prevention and Control, National Institutes regarding utilization of the Pap Smear have been made and published as the Bethesda System. In general terms, the recommendations are: 1. The cytopathology report is a medical consusltation. 2. The PAPANICOLAOU classification for reporting consultations is not acceptable in the modern practice of diagnostic cytopathology. 3. The recommendations made by participant and here published, should serve as a guideline for reports. 4. All reports should include: a. A statement regarding adequacy. b. A designation of normal of otherwise. c. A descriptive diagnosis
