Predictive Factors for Complete Myoma Resection During Hysteroscopic Myomectomy

The aim of this observational retrospective analysis is to evaluate predictive factors for complete myoma resection during hysteroscopic myomectomy for developing and validating a nomogram.

This tool can help clinicians to support the patient in making an informed decision about therapeutic options for uterine submucous myomas by defining risk factors predicting a high complexity myomectomy.

Overall, 10% of all uterine myomas are submucosal. These myomas spread into the uterine cavity, lifting the endometrial mucosa, and are a common cause of abnormal uterine bleeding, dysmenorrhea, early miscarriage and they may be a cause of infertility.

Hysteroscopic myomectomy is the surgical procedure of choice for the treatment of submucosal myomas, because it is minimally invasive and has the advantage of preserving the integrity of the uterine wall.

The characteristics of the myomas (size, number and location) enables the surgeon to choose the surgical approach that will provide the best outcome for the patient, and may predict the chances of a complete hysteroscopic resection of myomas in one procedure.

Eligibility Criteria:
Inclusion Criteria:

* patients with ultrasonographic diagnosis of uterine myomas

Exclusion Criteria:

* patients with previous incomplete hysteroscopic myoma resection;
* patients undergoing additional surgical procedures performed by hysteroscopy (such as, resection of endometrial polyps);
* patients undergoing associated non-hysteroscopic surgical procedures;
* patients with severe cardiovascular disease, decompensated diabetes and severe hematologic disorders
Conventional Mechanical Ventilation and High Frequency Percussive Ventilation: Comparison of Their Effects on Alveolar Recruitment and Distension by CT-scan in Early ARDS Patients

High frequency percussive ventilation (HFPV) is a high frequency ventilation mode in which high frequency pulses accumulate to generate a low frequency tidal volume at a controlled airway pressure. Previous studies have suggested a protective effect of HFPV on lung injury. The goal of our study is to compare, in early ARDS patients, the effects of conventional mechanical ventilation and of high frequency percussive ventilation on alveolar recruitment and distension evaluated by CT-scan


Eligibility Criteria:
Inclusion Criteria:

* Patient undergoing invasive ventilation for more than 24h
* ARDS patient

Exclusion Criteria:

* Pneumothorax drained or not
* Patient undergoing extracorporel mechanical oxygenation
* Patient who had a pneumonectomy partiel or total
Aberrant DNA Methylation to Predict Metachronous Gastric Neoplasms

The study is a prospective cohort study to investigate whether aberrant DNA methylation can be useful for the prediction of metachronous recurrence after endoscopic resection of gastric neoplasms (dysplasia or cancer). From 2012 to 2017, 300 patients were prospectively enrolled after endoscopic resection (ER) of gastric dysplasia or early gastric cancer. All lesions were assessed by endoscopy and biopsy before ER. Endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) was performed for gastric dysplasia and early gastric cancers which met the absolute indication (differentiated adenocarcinoma, intramucosal cancer, lesions \< 20 mm, and no endoscopic evidence of ulceration). All lesions were curatively resected; if non-curatively resected, the patients were not enrolled from the study. All subjects, who provided informed consent, were asked to complete a questionnaire under the supervision of a well-trained interviewer. The questionnaire included questions regarding demographic data (age, sex), socioeconomic data (smoking, alcohol, and education), their family history of GC in first-degree relatives, and history of H. pylori eradication therapy. Also, MOS methylation level at baseline was measured from noncancerous gastric mucosae at corpus. When H. pylori was positive by CLOtest or histology at baseline or during the follow-up, eradication therapy was done. To evaluate whether H. pylori was eradicated, 13C-urea breath testing was performed at least 4 weeks after completion of the eradication therapy. All study subjects were closely followed up since recurrent tumors at previous endoscopic resection sites can be easily detected on endoscopy with biopsy and treated during follow-up. Patients with local recurrence underwent further treatments, including repeated ESD, APC, and gastrectomy based on pathology, and patients who refused treatment received supportive care. All patients underwent endoscopy with biopsy within 6 months, then at 12 months after ESD to check for metachronous lesions or local recurrences. After 12 months, endoscopy with biopsy was performed annually. In case of EGCs, abdominal CT scan was performed in the first year and biennially thereafter to detect lymph node or distant metastases. The definition of the completion of the study protocol was 1) endoscopic and/or radiologic follow-up for more than 3 years, or 2) development of metachronous gastric neoplasm (primary outcome: gastric dysplasia or cancer) during the follow-up. Metachronous recurrence was defined as secondary dysplasia or cancers detected \> 1 year after initial diagnosis.


Eligibility Criteria:
Inclusion Criteria:

* Patients who underwent endoscopic resection of gastric neoplasms (dysplasia or early gastric cancer)
* All gastric neoplasms at diagnosis should be curatively resected before enrollment.

Exclusion Criteria:

* Previous history of all cancers.
* Previous history of gastrectomy
* Non-curative resection of gastric neoplasms
* Refusal to consent
Apolipoprotein E Gene and Functional MRI

1. Apolipoprotein E gene (ApoE) is the most important genetic factor for Alzheimer disease (AD) and an important genetic factor for outcome of brain injury situations.
2. Function magnetic resonance imaging (fMRI) is a powerful tool for study of both brain regional functions and brain network.
3. Study about genetic contribution on fMRI is an emerging concept, which will help on understanding about how the genetics affecting the brain function.

There are about 4-10% people aged and over 65 years suffering from dementia in Taiwan. Dementia caused by diverse diseases, including Alzheimer's disease (AD), fronto-temporal dementia (FTD), dementia with Lewy body (DLB), Parkinson's disease dementia (PDD) and vascular dementia (VaD), is a neurodegenerative disease characterized by memory impairment, cognitive dysfunctions, behavioral disturbances and various kinds of psychiatric manifestations. AD is the most common cause of dementia in the world. Although the real pathophysiology of AD is still obscure, the compelling evidence has shown genetic factor should play an important role in the occurrence of AD. There are three genes, in terms of amyloid precursor protein (APP), presenilin-1 (PS1) and presenilin-2 (PS2), linked in the familial AD. Mutations on these genes would result in familial AD, which account for only less than 5% of AD. The only one well-documented genetic risk factor for sporadic AD is apolipoprotein E, ε4 allele (ApoE4). ApoE gene contains three genetic polymorphisms, ε2, 3, 4 and ApoE4 has been found associated with many brain injury situations, such as poor outcome for traumatic brain injury (TBI), Parkinson disease dementia (PDD). These findings might support ApoE to be important for brain functions but the real mechanisms remain further clarification. Functional magnetic resonance imaging (fMRI) is a powerful tool for study of both brain regional functions and brain network. To our knowledge, only few reports in top journals indicated genetic background is an important contributor for fMRI presentations. This could be a new filed of neuroscience. In this study, we will explore whether ApoE genetic polymorphisms affect the presentation of fMRI and realize some functions of ApoE in the brain. In addition, our data could enhance the new concept about the association between genetics and brain function.

Eligibility Criteria:
Inclusion Criteria:

* people aged 45-65 years without cognitive impairment

Exclusion Criteria:

* unable to take APOE genotyping or undergo functional MRI

Evaluation of Respiratory Specimens for Bacterial and Viral Pathogens by Real-Time PCR

Community acquired pneumonia(CAP) is a common cause of morbidity and mortality. The diagnosis of CAP from the microbiology perspective has been challenging. Recent reports suggest the utility of real-time PCR for rapid and accurate diagnoses of these pathogens. Real-Time PCR tests, using the LightCycler instrument, will be performed on excess or additional specimens after extraction of nucleic acid.

Excess patient specimens normally collected for routine microbiologic testing for CAP and in some cases additional specimens (i.e.,blood, urine, throat swab) will be evaluated using real-time PCR tests developed in our laboratory. Specimens will be performed on patients suspect for CAP. Test will be directed at variety of pathogens including but not limited to M.pneumoniae, C. pneumoniae, Legionella pneumophila, Streptococcus pneumoniae, B. pertussis, influenza viruses, adenovirus, and metapneumovirus. The ultimate goal is to have a panel of highly accurate and rapid (same day) tests that can be orderable and performed in short period time for CAP cases.

Real-Time PCR tests, using the LightCycler instrument, will be performed on excess or additional specimens after extraction of nucleic acid. Real-time PCR tests, using the LightCycler instrument, will be performed on excess or additional specimens after extraction nucleic acid. These tests will include the organisms listed above. As nucleic acid extracts will be archived, other pathogens can be tested in the future should we develop additional real-time PCR tests. All results obtained by real-time PCR will be compared to results for conventional testing as listed above. Sensitivity, specificity and predictive values will be calculated. In cases where discordant results occur, additional PCR testing and or medical history review will be conducted.

Eligibility Criteria:
Greater than 18 years of age. Cough present greater than one day and a history of fever and chills or documented fever in the Emergency Department
Refractive and Corneal Topographic Characteristics in Upper Egypt Children With High Cylinder

Refractive and Corneal Topographic Characteristics in upper Egypt children with high cylinder: A cross sectional study

Astigmatism is defined as, a refractive condition in which refractive light fails to form a focus on the retina, it accounts for about 13% of refractive errors. It is frequent and correctable cause of visual impairment in children whether associated with spherical errors or not.

Astigmatism, is the refractive error of the highest clinical importance, being associated with reduced visual acuity with subsequent development of refractive amblyopia.

High cylinder in children belong to areas of hot and dry climates, makes exclusion of keratoconus is mandatory. Population in the African continent, the Mediterranean countries, Central and South America, and the Indian subcontinent usually have the habit of eye rubbing because of bothering symptoms of dryness, itching, atopy, allergy and vernal keratoconjunctivitis, which is the severe form of allergic conjunctivitis.

Eye rubbing causes thinning of keratocyte and increases the prevalence of keratoconus.

Keratoconus in children (diagnosed before the age of eighteenth) is less common but more aggressive than that of the adults, due to the dynamic nature of the young cornea. Few studies in the literature reported the prevalence and incidence of keratoconus in children.

Pentacam is an advanced instrument with a rotating Scheimpflug camera for scanning the anterior and posterior corneal surfaces. Its measurements of the corneal thickness and posterior elevation have been proved to be of high reproducibility and repeatability.

Eligibility Criteria:
Inclusion Criteria:

- Upper Egypt children with high cylinder(refractive errorr).

Exclusion Criteria:

* Children below age of 7 years old (uncooperative), patients above age of 18 years old.Patients with corneal scars

Identification of Diagnosis Biomarkers in the Tears of Alzheimer's Disease Patients: the COG-EYE Pilot Study

The diagnosis of Alzheimer's disease (AD) relies on the detection of protein biomarkers, particularly in cerebrospinal fluid (e.g., Aβ and phosphorylated Tau) or through brain imaging. The invasive nature of lumbar puncture and the numerous contraindications have driven the search for early and reliable diagnostic biomarkers for AD.

Human tears are an accessible biological fluid that has proven relevant in the biomarker search strategy for both ophthalmological and systemic diseases, especially neurodegenerative conditions. Advances in methods for low-volume analysis have facilitated the identification of tear biomarkers. Total tau has been reported as elevated in the tears of patients with AD compared to controls (n=65). Additionally, metabo-lipidomic analyses offer several advantages (accessibility, non-invasiveness, reproducibility) and also appear promising as a diagnostic tool for systemic and neurodegenerative diseases, such as amyotrophic lateral sclerosis. This supports the relevance of comparing both AD proteins biomarkers and metabo-lipidomic signatures in the tears of patients with AD (Mild Cognitive Impairement (MCI) and dementia) with healthy controls.

Study of the Metrological Properties of Two Assessment Grids of the Driving Capacity After a Cerebrovascular Accident (ROADTRIP)

Precise recommendations concerning the methods of evaluation for the resumption of the driving after a not evolutionary stroke were recommended recently by the High Authority of Health. These describe among others elements to be estimated during the test on the road, in the presence of the driving instructor who remains Gold standard.

However, no standardized assessment grid serving as decision-making tool is at present validated.

Actually the test made by the unit of evaluation of the automobile resumption of the university hospital on the road, in a car of apprenticeship with double pedals and in the presence of a professional binomial (driving instructor and occupational therapist) then validated by the opinion of the doctor of the service. The current standard is thus very subjective and lack of sensibility.

It is necessary to study the metrological properties of both available assessment grids (that established from the recommendations of the HAS and TRIP), none of them reached a level of validation enough in this population.

The TRIP is this day validated only at the elderly people. The hypothesis of the search is an insufficiency of TRIP to estimate the patients presenting aftereffects of cerebrovascular accident.

The main objective of this work is to validate the new assessment grid after a study of its metrological properties in the situation of the driving on the road.

The patients will benefit a medical consultation to estimate the possibility of inclusion in the study. During this consultation, the results of the neuropsychological and ophthalmological examinations will be explored and a specificity of the sensitive-driving deficits presented by the patient will be estimated to recommend the arrangements of necessary vehicle if necessary.

All the inclusive patients will benefit then the first test of driving in "ecological" situation accompanied by a lasting driving instructor during 45minutes. The evaluation will be realized by a present occupational therapist and a neuropsychologist in the vehicle, on two different assessment grids.

The second test on road will be for the part of included patients and will be made with the driving instructor and the therapist.

Then, the third test on road will be realized after sessions on driving simulator for the part of the patients requiring a re-entrainment.

Eligibility Criteria:
Inclusion Criteria:

* 18 Years to 80 Years
* Cognitive and/or sensitive-motor disorders after a cerebrovascular accident
* Candidate for resumption of driving on the road and having to pass an aptitude test
* French legal protection

Exclusion Criteria:

* Contraindications for resumption of driving on the road (visual field amputation, binocular visual acuity less than 5/10; cognitive impairment not compatible with driving; other medical contraindication).
* Protected populations not concerned by the study (guardianship, curatorship, deprived of the freedoms, safeguarding of justice).
Risk Factors for Enhanced Inflammation to Arthroplasty Wear Particles: Analysis of Cytokine Production and Polymorphisms

Assessment of cytokine polymorphisms in 100 patients with aseptic complications to arthroplasty as compared to 100 symptom-free arthroplasty patients.
