RESUMO
Background: Core needle biopsy (CNB) guided by imaging modalities seems to be an acceptable modality for diagnosis of lymphoma due to its safety, good applicability, availability as well as diagnostic accuracy, however; Studies have not reached a consensus on its diagnostic accuracy and factors affecting its performance. The present study aimed to assess the value of ultrasound-guided cervical CNB in the diagnosis of lymphoma in suspected patients. Materials and Methods: This cross-sectional study was performed on 46 consecutive patients (20 to 82 years) with cervical mass or lymphadenopathy suspected of lymphoma and were candidates for diagnostic evaluation. Ultrasound-guided core needle biopsies (UGCNB) were done by a single radiologist under guided ultrasonography. The diagnostic value of UGCNB in the diagnosis and determination of specific lymphoma subtypes was assessed. Results: Using UGCNB led to the diagnosis of lymphoma in 34.8% and non-lymphoma lesions in 43.5%, while the diagnosis remained unclear in other 21.7% with a total UGCNB-based identification rate of 78.3%. No patient with lymphoma was missed. All patients were followed up over a 6-month period. In none of the cases, clinical diagnosis and treatment response were found contrary to the initial pathologic diagnosis. No significant complication such as hematoma or infection was reported. Conclusion: UGCNB has a high diagnostic value for determining the nature of the cervical lesions suspected of lymphoma.
RESUMO
BACKGROUND: Cardiac and respiratory arrest is reversible through immediate cardiopulmonary resuscitation (CPR). However, survival after CPR is very low for various reasons. This systematic review study was conducted to assess the effect of palliative care on quality of life and survival after CPR. METHODS: In the present meta-analysis and systematic review study, two researchers independently searched Google Scholar and MagIran, MedLib, IranMedex, SID, and PubMed for articles published during 1994-2016 and containing a number of relevant keywords and their Medical Subject Headings (MeSH) combinations. A total of 156 articles were initially extracted. RESULTS: The success of initial resuscitation was reported to be much higher than the success of secondary resuscitation (survival until discharge). Moreover, the early detection of cardiac arrest, a high-quality CPR, immediate defibrillation, and effective postresuscitation care improved short- and long-term outcomes in these patients and significantly affected their quality of life after CPR. Most survivors of CPR can have a reasonable quality of life if they are given proper follow-up and persistent treatment. CONCLUSIONS: Concerns about the low quality of life after CPR are therefore not a worthy reason to end the efforts taken for the victims of cardiac arrest. More comprehensive education programs and facilities are required for the resuscitation of patients and the provision of post-CPR intensive care.
