Kidney cancer in the Middle East and North Africa region: a 30-year analysis (1990-2019).

Kidney cancer, a type of urogenital cancer, imposes a high burden on patients. Despite this, no recent research has evaluated the burden of this type of cancer in the Middle East and North Africa (MENA) region. This study explored the burden of kidney cancer from 1990 to 2019 according to age, sex and socio-demographic index (SDI). The Global Burden of Disease (GBD) 2019 data was utilized to estimate the incidence, death, and disability-adjusted life-years (DALYs) caused by kidney cancer. These estimates were reported as counts and as age-standardised rates with 95% uncertainty intervals (UIs). The estimated age-standardised incidence, mortality, and DALY rates of kidney cancer in 2019 were 3.2 (2.8-3.6), 1.4 (1.2-1.6), and 37.2 (32.0-42.6) per 100,000, respectively. Over the period from 1990 to 2019, these rates have increased by 98.0%, 48.9%, and 37.7%, respectively. In 2019, the United Arab Emirates, Qatar, and Lebanon had the largest age-standardised incidence, mortality, and DALY rates. The smallest age-standardised incidence rates were seen in Yemen, Afghanistan, and the Syrian Arab Republic. Additionally, the smallest age-standardised mortality and DALY rates were observed in the Syrian Arab Republic, Yemen, and Morocco. The highest incidence rates were found among individuals aged 75-79 in both males and females. In 2019, the MENA/Global DALY ratio exceeded one for females aged 5-19 age and males aged 5-14, compared to 1990age groups in males. The burden of kidney cancer consistently rose with increasing SDI levels from 1990 to 2019. The increasing burden of kidney cancer highlights the urgent need for interventions aimed at improving early diagnosis and treatment in the region.

The burden of testicular cancer from 1990 to 2019 in the Middle East and North Africa region.

Background: The incidence rate of testicular cancer has risen in many countries during recent decades. This study aimed to outline the impact of testicular cancer on the Middle East and North Africa (MENA) region from 1990 to 2019, examining its burden by age group and according to the socio-demographic index (SDI). Methods: Data on the incidence, death, and disability-adjusted life-years (DALYs) due to testicular cancer were retrieved from the Global Burden of Disease study 2019. The counts and age-standardized rates (per 100,000) were reported, and all rates were accompanied by 95% uncertainty intervals (UIs). Results: In MENA, the age-standardized incidence rate of testicular cancer was 1.4 per 100,000 in 2019, showing a 244.0% increase since 1990. Similarly, the annual death rate, at 0.1, experienced a 2.6% rise during the same period. In 2019, testicular cancer accounted for 31.1 thousand DALYs, marking an age-standardized rate of 5.0, which was 2.8% higher than in 1990. The 1-4 age group exhibited the largest incidence rate in 2019. In addition, in both 1990 and 2019 the MENA/Global DALY ratio was higher than one in the 1-14 year age groups. During the period 1990 to 2019, the age-standardized DALY rate of testicular cancer steadily rose with higher SDI values, except for a decrease observed at an SDI of 0.8. Conclusion: Over the last thirty years, there has been a notable rise in the burden of testicular cancer in the MENA region.

Testicular papillary serous carcinoma of ovarian type, a rare case report, however an important timely diagnostic issue.

A 28 years old man presented with left testicular swelling for recent few months. Ultrasonography and Computed tumor scan was in favor of solid cystic mass. The patient underwent left radical orchiectomy. The pathology diagnosis with aid of Immunohistochemistry staining approved the mullerian duct origin. Papillary serous carcinoma of ovarian type(PSCOT) is diagnosed for him. The patient treated successfully he was symptom free in two years follow up after orchiectomy. Timely diagnosis of PSCOT and orchiectomy are the keys of the patient survival; because prior to tumor spreading, the patient can be discharged after orchiectomy without adjuvant treatment.

Scrotal leiomyoma a rare benign intra-scrotal mass could lead to unnecessary orchiectomy.

Leiomyoma is a benign tumor originating from smooth muscle cell, Mostly from uterus. However, in men is a very rare entity. Scrotal leiomyoma is a very rare tumor. Here we presented a case of scrotal leiomyoma in a 71-year-old man. He presented with a slowly growing, painless mass and heaviness in the left testis for 10 years. Due to huge size, testicular attachment and preoperational diagnosis of atypical leiomyoma/leiomyosarcoma, orchiectomy was performed. Pathology report diagnosed leiomyoma. We suggest frozen section diagnosis as a useful tool, to prevent unnecessary procedure.

The effects of dopaminergic drugs in the ventral hippocampus of rats in the nicotine-induced anxiogenic-like response.

Nicotine an active alkaloid of tobacco has dopaminergic properties. The drug alters anxiety-like behavior in rodents. Ventral hippocampus (VHC) may be a site for modulation of anxiety-like behaviors. The possible involvement of ventral hippocampal dopaminergic receptor mechanism in the nicotine influence on anxiogenic-like response has been investigated in the present study. The effects of apomorphine, sulpiride and SCH23390 on nicotine response in elevated plus maze in rats have been investigated. Intraperitoneal administration of nicotine (0.6mg/kg) decreased percentage of open arm time (%OAT) but not percentage of open arm entries (%OAE) and locomotor activity, indicating an anxiogenic-like response. Intra-hippocampal injection (intra-VHC) of apomorphine, a D(1)/D(2) dopamine receptor agonist (0.1 and 0.2microg/rat) also caused anxiogenic-like effects, but the drug blocked that of nicotine. Intra-VHC administration of the D(2) receptor antagonist, sulpiride (1, 2.5 and 5microg/rat) or the D(1) receptor antagonist, SCH23390 (0.01, 0.1 and 1microg/rat) did not elicit any response. However, pretreatment with sulpiride (1microg/rat) or SCH23390 (0.1microg/rat) decreased nicotine's effect. The results may indicate a modulatory effect for the D(1) and D(2) dopamine receptors of VHC in the anxiogenic-like response induced by nicotine.
