For the first time panic disorder and agoraphobia are included as separate disorders in the DSM-5. Thus, agoraphobia no longer represents a subcategory of panic disorder. To diagnose both of the disorders, questionnaires are the method of choice. However, there are no measuring instruments available free of charge in German-speaking countries. In order to improve this situation, the Witten Panic Disorder Questionnaire (WPF) and the Witten Agoraphobia Questionnaire (WAF) are constructed in accordance with the DSM-5 criteria. Both measuring instruments are included as a part of a ten instrument battery. WAF and WPF will be delivered to a patient sample of patients with panic disorder and/or agoraphobia as well as depressed patients (discriminant validity). Factor analyzes and item analyses will be conducted.

Beta thalassemia has many complications on many systems as the renal system.So early detection of renal impairment is required in those children to decrease complications of this nephropathy.

Tacrolimus is the most widely used immunosuppressive drug in the prevention of rejection after solid organ transplantation. Pharmacokinetic studies in healthy volunteers and in transplanted patients have shown that this molecule is rapidly absorbed after oral administration (maximum plasma concentration after 1-2 hours), is found in the circulation bound mainly to erythrocytes and, after being metabolized by CYP3A4, is eliminated through the bile. The importance of the tacrolimus blood dosage is now widely recognized for detecting the immunosuppressive capacity reached in the individual patient or the eventual overdose of the drug. In the use of Tacrolimus after Liver Transplantation, however, it is interesting to note that the biochemical pathway for metabolism and excretion of the drug is present in the transplanted organ, the main object of immunological and functional surveillance. The excretory capacity of Tacrolimus by the liver through the bile, therefore, could be a useful tool for recognizing the early liver failure from a functional point of view, before the onset of hepatoecrosis.

The current research focus for cancer diagonosis is classical genetics, named "driving genes". However, not all cancer patients have typical genetic alterations, especially at early stage. In the past dacades, accumulating evidences have revealed that more than 80% diseases are closely related to epigenetic changes. The normally silenced copy of imprinted genes are reactivated at early stage of cancers, and finally proceed to copy number variation. This study will screen for a panel of imprinted genes and build quantitative models to assist the diagnosis of multiple cancers.

The investigators aim to identify preoperative Electroencephalogram (EEG) markers indicating patients at risk to develop postoperative delirium (POD), so that the anesthetist may adjust medications and dosages in order to avoid POD. Second, the investigators aim to specify intraoperative EEG signatures and EEG states that are related to POD and long-term cognitive dysfunction, again to enable physicians to adapt their procedure. Third, the investigators aim to identify EEG signatures during stay in the recovery room that is directly related to POD, and may therefore be used as diagnostic tool, as well as a predictor for the development of long-term cognitive deficits (POCD).

A general term, dental anxiety, is defined as fear or an abnormal concern to visit the dentist for unwanted concerns about preventive care and dental procedures. anxiety; dental examinations or treatment can be prevented or postponed. This delay in dentistry typically leads to much more serious dental problems, often leading to more expensive, more invasive and possibly emergency treatment. Therefore, reducing anxiety is important both in terms of patient, physician and cost.

Analyze the epidemiology and outcome of all patients with heart failure with reduced ejection fraction (HFrEF) presented to Asyut university hospital (AUH) and to identify factors associated with mortality and all-cause hospitalization at a duration of 6 months follow-up.

The aim of the study was to determine the incidence and factors associated with double-J urinary stent infection.

The aim of this study is to determine the impact of endoscopic transsphenoidal pituitary surgery on nasal function using a numerical simulation and to compare the difference between two kinds of transsphenoidal approachese(single nostril approach and bilateral nostril approach)．

Study's purpose is to determine if a patient's perception of readiness for discharge from sub-acute rehabilitation, as measured by Readiness For Hospital Discharge Scale Patient Self-Reports Form, correlates with the patient's success after discharge, measured by patient reported number of falls, emergency room visits and hospitalizations 30 days post discharge.
