Buschke–Lowenstein Tumor (BLT) or Giant Condyloma Acuminatum (GCA) is a slow-growing, locally aggressive, cauliflower-like tumor of great size that usually arises in the perineal region. Buschke–Lowenstein Tumor is triggered by human papilloma virus (HPV), usually either genotype 6 or 11. Buschke–Lowenstein Tumor is usually preceded by condyloma acuminatum and occurs at any age after puberty, usually between the 4th and 6th decades. Invasive overgrowth and recurrence after treatment are its characteristics and malignant transformation is also possible. Here, we have reported a case of a 33 year-old man with penile Buschke–Lowenstein Tumor arising from common genital warts.

Background and Objective: Since the onset of the COVID-19 (Corona Virus Disease 2019) pandemic, several challenges have been proposed to the disease and the causing viral agent. Accurate and rapid diagnosis of the virus is essential to control the spread and progression of the disease. Choosing a suitable sample in different phases of the disease will reduce the false-negative results. This study was performed to identify the SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) genome in the blood samples of COVID-19 patients.
Methods: This descriptive-analytical study was performed by census method on 100 whole blood samples of patients (50 recovery and 50 deceased) with a definitive diagnosis of COVID-19 (positive Real-Time RT-PCR test of nasopharyngeal swab samples) admitted to Shahid Sayyad Shirazi educational and medical center in Gorgan during 2020-21. Clinical and laboratory findings were compared in the two groups of patients. The viral nucleic acid was extracted from the whole blood samples of the patients, and the presence of the virus genome was investigated using primer and probes via the Real-Time RT-PCR method.
Results: The age of the recovered patients (49.06±15.1 years) was significantly was lower than deceased patients (58.3±12.4 years) (P<0.05). Clinical symptoms including cough, shortness of breath, sputum secretion, and vomiting in deceased patients were significantly more than recovery group (P<0.05). The lymphocytes count and platelet level in the deceased group were lower than in the recovered group. Level of lactate dehydrogenase (LDH) was higher in the deceased group in compare to recovered group (P<0.05). The virus genome identified in the blood samples of 7 patients (3 recovered and 4 deceased), which had no significant relationship with the outcome of the disease.
Conclusion: The use of blood samples for the diagnosis of COVID-19 is not appropriate.

Background and Objective: Major depression is a common disease in the world, which is associated with cognitive impairment. Executive functions are among the cognitive functions that are influenced by major depression. This study was conducted to comprehensively evaluate the executive functions of people with major depressive disorder and normal people using the Cambridge Neuropsychological Test Automated Battery (CANTAB).
Methods: This case-control study was conducted on 13 patients with major depressive disorder and 13 normal individuals aged 21 to 35 years who were referred to psychology and psychiatry centers in Tehran (Iran) in 2019. The subjects were randomly selected from six centers in four districts of Tehran and then divided into an experimental group and a healthy control group. Both groups were subjected to cognitive assessment using the CANTAB, n-back test as well as Daneman and Carpenter's working memory sentences.
Results: The mean of executive functions was significantly lower in people with major depressive disorder compared to their healthy counterparts (P<0.05). When examining the components of executive functions in both the experimental and control groups, there was a significant increase in the shifting in the total number of errors and the inhibition component in direction errors. In addition, there was a statistically significant decrease in the updating component in errors 1 and error 2 and an increase in time 2. Furthermore, there was a significant increase in the component of working memory maintenance in error as well as the planning component in the average delay (response speed) to the first choice, to correct the error and a decrease in working memory manipulation (P<0.05).
Conclusion: Our findings indicate that the executive functions of people with major depressive disorder are lower than healthy counterparts according to the CANTAB.
