Background: Thyroid carcinoma is the most common malignancy of the endocrine system. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. Thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. As a result of diagnostic methods improvement, prevalence of this tumor is increasing. In this study we reviewed different characteristics of tumor. Methods: We searched various factors about this tumor in different databases (PubMed, Ovid, Google scholar, Iran medex and SID databases,July 2012 till August 2013), after that the articles were classified. Data of each article were extracted and sorted in tables.Data of each factor in different articles were summarized. Results:Etiology, clinical presentation, prognosis, histopathology, follow-up, diagnosis and also age, gender, tumor size and treatment were factors about this tumor described in details here. Conclusion: Awareness and better understanding of the characteristics of this tumor and manage it as an individual and valuable tumor can take an effective step in promoting public health practice.

Background: Cryptosporidiumis known as an opportunist disease-causing agent in man in recent decades. It causes diarrhea and intestinal disorders in the immune deficit and immune competent individuals. This study was aimed to investigate the clinical characteristics of HIV/AIDS patients withcryptosporidiosisinfection. Methods: This cross-sectional descriptive study was performed on 53 HIV/AIDS patients referred to the Behavior Disease Consultation Center of Imam Khomeini Hospital in Tehran, Iran in 2013. First, the patients were studied clinically and the context data were recorded in a questionnaire for parasitological examination and referred to the laboratory for eosinophil count, and CD4 count per ml of blood. Results: Cryptosporidiosiswas observed in 4 (7.6%) of the total 53 HIV/AIDS patients. The highest prevalence of infection was observed in the age range of 30-39 yr.Itwas observed in different sexes as 5.7% of male and 1.9% of female, but statistically was insignificant (P=0.163).75% of patients had no intestinal symptom, 11.4% with acute diarrhea and 3.8% with chronic diarrhea. Cryptosporidiosis cases were observed in 5.7% of patients without intestinal symptom. Conclusion: Practitioners in the clinicalexamination for the detectionof the opportunistic intestinal protozoan infection should use clinical and paraclinical characteristics of the HIV/AIDS patients for the diagnostic of Cryptosporidium and other opportunistic parasitic diseases.
