Cytomegalovirus in solid organ transplant recipients
Cytomegalovirus in solid organ transplant recipients samer kareem 1,508 Views • 3 years ago

Cytomegalovirus (CMV) continues to have a tremendous impact in solid organ transplantation despite remarkable advances in its diagnosis, prevention and treatment. It can affect allograft function and increase patient morbidity and mortality through a number of direct and indirect effects. Patients may develop asymptomatic viremia, CMV syndrome or tissue-invasive disease. Late-onset CMV disease continues to be a major problem in high-risk patients after completion of antiviral prophylaxis. Emerging data suggests that immunologic monitoring may be useful in predicting the risk of late onset CMV disease. There is now increasing interest in the development of an effective vaccine for prevention. Novel antiviral drugs with unique mechanisms of action and lesser toxicity are being developed. Viral load quantification is now undergoing standardization, and this will permit the generation of clinically relevant viral thresholds for the management of patients. This article provides a brief overview of the contemporary epidemiology, clinical presentation, diagnosis, prevention and treatment of CMV infection in solid organ transplant recipients.

Isolated sphenoidal sinusitis
Isolated sphenoidal sinusitis samer kareem 4,998 Views • 3 years ago

Results Sinusitis was characterized as acute in 26 patients, subacute in 5 (including 1 pyocele), and chronic in 8 (including 2 fungal infections). No tumors were found. Isolated sinus cysts were excluded from the study. Headache, the main symptom in 32 patients (82%), was localized most commonly on the vertex. Other common complaints were rhinitis, dizziness, eye symptoms, and fever. In 2 patients, the finding was occult. Eight patients (21%) presented with cranial nerve deficits, and 1 patient had an intracranial complication. Sinus irrigation was performed in 16 patients (41%) and sphenoidotomy was performed in 10 (26%). Fifteen patients (38%) were treated with antibiotic drugs alone. Within 3 months, 31 (84%) of 37 patients had recovered from the illness; 5 still experienced headaches despite having normalized radiographic findings; and 1 had permanent unilateral visual loss. Two patients were lost to follow-up.

Gynecological History
Gynecological History samer kareem 4,192 Views • 3 years ago

General Considerations Because a discussion of reproductive issues may be difficult for some women, it is important to obtain the history in a relaxed and private setting. The patient should be clothed, particularly if she is meeting the provider for the first time. Ordinarily, the patient should be interviewed alone. Exceptions may be made for children, adolescents, and mentally impaired women, or if the patient specifically requests the presence of a caretaker, friend, or family member. However, even in these circumstances, it is desirable for the patient to have some time to speak with the clinician privately. The manner of address should be formal using the title Mrs., Ms., Miss, or Dr. with the patient’s surname, unless the patient requests otherwise. In some settings, it may be appropriate for nursing staff to be involved with history taking. A nurse may be perceived as less threatening, and may be able to take the history in a less hurried manner.1 The provider can verify the history and focus on areas of concern. Alternatively, it may be helpful to ask the patient to complete a self-history form on paper or by computer prior to speaking with the provider. This allows the provider to devote time to addressing positive responses, and ensures that important questions are not missed. Hasley2 showed that responses to a computer-based questionnaire designed to update a patient’s gynecologic history were equivalent to those obtained during a personal interview. Several studies involving patients in non-gynecologic settings have shown that patients are more likely to provide sensitive information when responding to a computer-based questionnaire as opposed to a personal interview or even a paper questionnaire.3 In order to increase a patient’s level of comfort during the interview, questions should be asked in an open-ended and nonjudgmental way. Assumptions should not be made about aspects of the patient’s background such as sexual orientation. At the conclusion of the interview, patients should be asked whether there are concerns that they would like to discuss that were not addressed previously in the interview.
