Abstract

Epidemiologically, the percentage of colorectal adenocarcinoma (CRC) in the age group ≤40 years old in Indonesia is higher than in the West European, North American and other developed Asian countries with different clinico-pathological features. In the afromentioned countries, the carcinogenesis pathway of this group is hereditary which show high microsatellite instability (MSI), whereas the age group >40 years old is sporadic of which show chromosomal instability (CIN) with the mutation of p53 gene. To elucidate the carcinogenesis pathway with its molecular characteristics of this group among Indonesians, a cross sectional study was conducted by performing the immunohistochemical detection of MLH1 and MSH2 expression (MSI status), and mutated p53 gene expression (CIN) in the CRC group ≤40 years old and >40 years old at Dr. Hasan Sadikin Hospital, Bandung, from May 2008 until November 2009. Thirty nine CRC patients, consisting of 22 patients of  ≤40 years old and 17patients >40 years old, were eligible for this study. The CRC patients of ≤40 years old showed 4 MSI high,  1 MSI lowand 17 MSS (microsatellite stable), associated with 10 p53 positive and 12 p53 negative status. In the CRC group of >40 years old, there was no MSI high, but 4 MSI low and 13 MSS were found, associated with 11 p53positive and 6 p53negative status. There was no significant difference with regards to the association between MSI status and p53 expression in both groups (p MSI=0.95, p p53=0.23).

Abstract

Objective: We would like to identify whether atherosclerotic plaque inside renal vasa recta correlates with the formation of calcium stone. Material & Method: Samples are taken from kidney tissue removed by nephrectomy due to stone and non-stone disease. Histopathological examination with specific staining was performed by a single pathologist to find the atherosclerotic plaques inside the renal vasa recta. The result of each group was compared, and then analyzed using the Chi square test/Fischer exact test (SPSS ver.16.0; p < 0,05). Results: We found that the risk of calcium lithiasis is two-fold higher in the group with atherosclerotic plaques inside the renal vasa recta. (PR = 2,15; p < 0,05). Conclusion: Calcium stone are more likely to occur on patients with renal vasa recta atherosclerotic plaque, as possible sequelae of vascular injury.Keywords: Atherosclerotic plaque, vasa recta, calcium renal stone.

Abstract

Objective: To evaluate the effect of prednisone in unilateral testicular torsion on Sertoli cell quality of contralateral testis. Material & Method: Thirty Wistar rats were divided into three groups i.e. group A (sham procedure), group B (unilateral torsion + orchiectomy after 6 hours), and group C (unilateral torsion + orchiectomy after 24 hours). Group B and C were further divided into subgroup with and without Prednisone administration. Prednisone was given orally once a day an hour after torsion, continued till one month later. Orchiectomy of contralateral testis was performed one month later. Those testes were examined by a pathologist. Results: In group A, no abnormality on Sertoli cell quality was found. There is significant difference among groups in Sertoli cell quality (p = 0,01). Ischemic time is associated with Sertoli cell quality (2 rats with severe damage in group C and none in group B). In group B and C, prednisone administration inhibited Sertoli cell damage. Prednisone administration in 6 hours group gave better results than 24 hours group (3 rats vs 1 rat with good Sertoli cell quality). Conclusion: Sertoli cell in contralateral testis is significantly affected by unilateral testicular torsion. Prednisone inhibit Sertoli cells damage. Ischemic time affected Sertoli cell quality of contralateral testis and respond to prednisone.Keywords: Prednisone, unilateral testicular torsion, sertoli cell.

Abstract

Objective: To analyze the distribution features of Gleason score in the different prostate zones. Material & Method: Twenty paraffin block specimens of radical prostatectomy were analyzed looking for Gleason score distribution in each zone. Specimens were stained with Hematoxilin Eosin. Results: Among the 20 cancers, 16 (80%) specimens had more than one focus. Most foci were found in peripheral zone (95%), only one specimen contained foci solely found in transitional zone. More than half (55%) prostate specimens contain three different Gleason grades. Only one specimen contained a single grade. Conclusion: Our results confirm the heterogeneous, multifocal, and multizonal nature of prostate carcinomas. Most specimens had more than one tumor focus, with predominant location in the peripheral zone. Almost all transition zone foci were found concomitantly with peripheral zone foci. Keywords: Prostate cancer, prostate zones, Gleason score.

Abstract

Objective: To assess the efficacy of pulsed holmium:YAG laser lithotripsy for ureteral stone therapy. Material and method: Ninety-one patients (70 males and 21 females) with age range 20 – 76 years underwent 93 ureteroscopic procedures for 101 ureteral stones. A preoperative diagnosis was established by ultrasound scanning and intravenous urography. An 8 F rigid Karl-Storz ureteroscope was used for a holmium:YAG laser (OmniPulse MaxTM 80 watt Holmium Laser System Model 1210-VHP, Trimedyne,Inc. Irvine CA, USA) as energy source for laser lithotripsy. The stone localization was mostly at the lower third of the ureter. The mean stone size was 9,6 mm, mean duration of procedure was 48,1 minutes, and the mean hospital stay was 2,1 days. Results: The overall stone clearance rate was 95,6% with the best results for stones in the middle third of the ureter (100%). At follow up we noted two patients with residual stones and two patients with a perforation of the ureteral wall. Conclusion: The Holmium:YAG laser is effective for ureteral stone treatment with a high success rate. Special attention and care should be afforded in impacted ureteral stones.

Abstract

Objective: To evaluate the sensitivity and the specificity of the ultrasound in predicting renal parenchyma laceration and perirenal hematoma in patients with abdominal blunt trauma with suspicion of renal trauma, as confirmed by operative findings in the explorative laparotomy. Material & methods: From March 2005 to March 2006, we found 28 patients admitted to the emergency department with abdominal blunt trauma with suspicion of renal trauma. Every patient was scanned sonografically to detect the presence of the renal parenchyma laceration and perirenal hematoma. All those patients underwent laparotomy for any certain indication, but not because of ultrasound findings. The ultrasound findings then were checked with the operative findings. Results: The sensitivity of the ultrasound in predicting renal parenchyma laceration is 53.8%, while its sensitivity in predicting perirenal hematoma is 75%. The specificity of ultrasound in predicting both renal parenchyma laceration and perirenal hematoma is 100%. Conclusion: Ultrasound for kidney trauma is sensitive in predicting the presence of perirenal hematoma, but not sensitive in predicting the presence of a renal parenchyma laceration. Ultrasound is very specific in predicting if both perirenal hematoma and renal parenchyma laceration are present.
