“…The mean age in our study was 56.3 years as compared to 64 years in the west (Thompson et al, 2008). In India too the mean age at diagnosis is same as ours (Reddy et al, 2012). The reason for this difference is not clear.…”

“…RCC is the most common, followed by Transitional cell carcinoma (12.5%), leiomyosarcoma (4.7%), oncocytoma, squamous cell carcinoma and high grade pleomorphic undifferentiated sarcoma (1.6% each). In an Indian study (Reddy et al, 2012) similar incidence of RCC was seen. However, Wilm's tumor was the second most common tumor in their study.…”

“…However, CRCC was not found in these studies but another study (Murphy et al, 2004) reported CRCC as 5% of RCC. A study in India also demonstrated CCRCC as the most common variant (90%) followed by PRCC and collecting duct variant (4.7% each) (Reddy et al, 2012). In our study collecting duct variant was not found.…”

Background: Renal cancer is a serious public health problem which may be under reported and registered in our setup, since the Karachi cancer registry documented only 43 cases out of 4,268 incident cancer cases over 3 year duration. Therefore we aimed to determine the clinicopathologic characteristics of adult renal tumors in our setup. Materials and Methods: The study was conducted in histopathology department, Liaquat National Hospital and included total of 68 cases of adult renal tumors over 4 years. Detailed histopathologic characteristics of tumors were analyzed. Results: Mean age of patients was 56.4 (18-84) years. Renal cell carcinoma (RCC) was the most common cell type (78%) cases; followed by transitional/urothelial carcinoma (12.5%), leiomyosarcoma (4.7%), oncocytoma (1.6%), squamous cell carcinoma (1.6%) and high grade pleomorphic undifferentiated sarcoma (1.6%). Among 50 RCC cases; 62% were conventional/clear cell RCC (CCRCC) type followed by papillary RCC(PRCC), 24%; chromophobe RCC(CRCC), 6% and sarcomatoid RCC(SRCC), 8%. Mean tumor size for RCC was 7.2 cm. Most RCCs were intermediate to high grade (60% and 40% respectively). Capsular invasion, renal sinus invasion, adrenal gland involvement and renal vein invasion was seen in 40%, 18%, 2% and 10% of cases respectively. Conclusions: We found that RCC presents at an earlier age in our setup compared to Western populations. Tumor size was significantly larger and most of the tumors were of intermediate to high grade. This reflects late presentation of patients after disease progression which necessitates effective measures to be taken in primary care setup to diagnose this disease at an early stage.

Background and Aim:Adult renal tumors (ARTs) are rare as compared with tumors of other organs and systems; however, it is important to have demographic and pathology data of rare tumors, including ART. No such data are available from the Kingdom of Saudi Arabia (KSA). Therefore, we aimed to study the demographic and pathological data of ART from King Fahad Hospital, Al-Madinah, KSA.Materials and Methods:This is a retrospective study of computerized data from the histopathology laboratory of King Fahad Hospital during a 10-year period (January 2006–September 2015).Results:There were 42 cases of ART, comprising 28 males and 14 females (male:female ratio of 2:1). The study group ranged in age from 17 to 83 years, with a mean of 54.5 years. In the study cohort, 93% of the patients had malignant tumors and 7% had benign lesions. Renal cell carcinoma (RCC) accounted for 85.8% of cases, followed by squamous cell carcinoma and sarcoma. The benign tumors recorded in our series were oncocytoma (4.7%) and angiomyolipoma (2.4%). The tumor size of RCC ranged from 4 to 17 cm, with a mean of 7.4 cm. The majority of patients (68%) had Fuhrman Grade II tumor. Gross capsular invasion, renal vein invasion and lymph node metastases were present in one case each.Conclusion:We conclude that the pathological findings of ART from the Madinah region are in concordance with studies in national and international literature.

Bluetongue (BT) is an insect borne (Culicoides) viral disease of small ruminants in India. While seroprevalence for BT is observed mostly in domestic and wild ruminant animals, the clinical form of disease and severe mortality is observed in sheep. Since the fi rst report of BT in 1960s the country became endemic for the disease and most of the BT virus (BTV) serotypes (22 out of 27 worldwide) have been reported. Th e genome sequence analyses of these viruses revealed that both the eastern and western topotypes as well as their reassortant strains are present in India. It further revealed that some of these viruses are very close to live vaccines used in other countries. Th e severe economic concern justifi es the need to develop sensitive and reliable diagnostic tests for BT. Th e virus isolation followed by identifi cation by electron microscopy is gold standard test, but it is time consuming and not easily available in all the laboratories. Th erefore, nucleic acid-based rapid diagnostic tests such as PCR, real-time PCR etc. are used nowadays. Th e BT control program in India includes vector control as well as eff ective vaccination. Th e vector population is controlled by vector traps, synthetic pesticides and some of the herbal compounds. For eff ective vaccination, the serotypes prevalent in a particular geographical area must be known, which can be achieved by continuous monitoring and sero-surveillance of disease. Th e multivalent inactivated vaccines are more suitable for India in comparison to modifi ed live vaccines as the latter may turn to virulent and may lead to severe outbreak of the disease.
