Abstract

Objective: The aim of the study was to investigate the difference of high risk DNA HPV elimination between cervical squamous cell carcinoma and cervical adenocarcinoma treated with chemoradiation and the possible correlation with the response to the chemoradiation.Material and method: Twenty two patients with cervical adenocarcinoma and 26 patients with cervical squamous cervical carcinoma who came to gynecologic oncology clinic of Dr. Cipto Mangunkusumo Jakarta between July 2005 and July 2006 (all the patients in both group were stage IB-IIIB according to International Federation of Gynecology and Obstetrics [FIGO] stadium) were tested using hybrid capture II (HC II) to identify the presence of high risk HPV DNA before they were treated with chemoradiation. After chemoradiation, the response was evaluated and all the patients were tested using HC II to determine the presensce of high risk HPV DNA after therapy. The clearance of HPV DNA and the response to chemoradiation in both group were studied.Results: Clearance of HPV DNA in squamous cell carcinoma group was non significantly higher than that in adenocarcinoma group. (76.9% vs 59.1%, p=0.310) and The persistance rate of HPV DNA in adenocarcinoma group was higher than that in squamous cell carcinoma group. This study showed that there was no difference in response to chemoradiation between adenocarcinoma group and squamous cell carcinoma group. Clearance of HPV DNA has no relation with response of therapy, even the tumour with complete response could still have a HPV DNA.Conclusion: Clearance of high risk HPV DNA was higher in cervical squamous cell carcinoma than in cervical adenocarcinoma. The persistence rate of high risk HPV DNA was higher in cervical adenocarcinoma than in cervical squamous cell carcinoma. Further study with longer follow up time is needed to prove the relation between the persistence of high risk HPV DNA and the recurrence of cervical cancer.Keywords: cervical cancer, HPV, chemoradiation

Abstract

Di jaman modern seperti sekarang ini terjadi fenomena persaingan antar individu di masyarakat agar tidak tertinggal dengan perkembangan arus globalisasi sangat pesat. masyarakat dituntut untuk memiliki skill dan pengetahuan yang luas. Kebutuhan akan pendidikan menjadi kebutuhan primer bagi masyarakat. Untuk memperoleh pendidikan tidak hanya didapat secara formal seperti disekolah tetapi juga dapat diperoleh secara tidak formal seperti membaca di perpustakaan. Namun sayangnya kesadaran masyarakat tentang minat baca dirasa masih sangat kurang. Dibutuhkan suatu perpustakaan dengan konsep yang menarik sehingga minat baca masyarakat dapat meningkat kembali. Perpustakaan yang baik dapat menjadi ruang publik yang menawarkan edukasi sekaligus hiburan yang dikemas secara berbeda. Faktor kenyamanan dan fasilitas yang baik harus benar-benar diperhatikan sehingga dapat mempengaruhi psikolgi pengguna perpustakaan agar minat bacanya meningkat. Metode desain yang digunakan meliputi pengumpulan data yang dilaksanakan secara langsung maupun tidak langsung. Pembagian kuisioner,wawancara dan pengamatan langsung ke lapangan untuk mengetahui apa yang dibutuhkan. Sedangkan studi pustaka, majalah, dan internet mengenai perpustakan, Post Modern dan nuansa interiornya merupakan cara untuk mendapatkan data pendukung, standar perancangan, perkembangan desain dan referensi tentang objek yang diperlukan. Data yang sudah didapat akan diolah menggunakan penghitungan data statistika dengan cara analisa deskriptif, analisa kesenjangan dan pertanyaan terbuka . Hasil yang diharapkan dari desain interior ini adalah merancang desain interior perpustakaan sebagai sarana edukasi dan hiburan yang dapat meningkatkan minat baca dan kreatifitas masyarakat luas.

Abstract

Objective: To determine relation between age and resistive index (RI) changes occurring after extracorporeal shock wave lithotripsy (ESWL). Material & Method: We performed a prospective study in Soetomo Hospital Surabaya. Using duplex ultrasonography, RI was determined in 20 patients with calyceal kidney calculi and pelvic kidney calculi. RI of the interlobar renal arteries were measured in the region near the calculi (distance, less than 2 cm), one hour before ESWL and RI was measured again at 1 hour, 3 days and 7 days after ESWL. Changes in RI values and relation with age (≤ 60 years old and > 60 years old) were evaluated. Results: The renal RI increased significantly 1 hour and 3 days after ESWL, but returned to before ESWL values 7 days after ESWL in the both groups. Although there was positive correlation between age and RI before ESWL, but there was no correlation between age and RI changes after ESWL. Conclusion: Renal RI is higher with age > 60 years, after ESWL renal RI showed transient increase which returned to baseline after 7 days.Key words: Color Doppler Ultrasonography, extracorporeal shock wave lithotripsy, renal resistive index, calyceal kidney calculi, pelvic kidney calculi.

Abstract

Objective: This study evaluated the correlation between preoperative urine culture and intraoperative stone culture and the impact of stone culture findings on post-operative systemic inflammatory response syndrome. Material & Method:Patients with kidney stones who underwent percutaneous nephrolithotomy (PCNL) from February to May 2012 were prospectively analyzed. A pre-operative urine culture was obtained in the morning before the operation, fragmented stone collected were cultured in Departement of Microbiology. Patients were monitored closely in the postoperative period for signs of systemic inflammatory response syndrome (SIRS). Results:A total of 33 patients underwent PCNL and examined for urine cultures, stone culture and postoperative SIRS, 15 (45.45%) patients with positive urine culture, 18 patients (54.54%) with positive stone culture but only 1 patient (3.03%) had same pathogen (p = 0.629). Ten patients (55.6%) with positive stone cultures had evidence of systemic inflammatory respose syndrome postoperatively. The calculated stone culture value for sensitivity, specificity, positive predictive value and negative predictive value were 100%, 65.2%, 55.6%, and 100%. Preoperative hydronephrosis (p = 0.003) and operative time (p = 0.001) are identified as the key risk factors for SIRS after PCNL.Conclusion: Positive stone culture are better predictors for SIRS after PCNL. Stone culture examination is an essential in directing the proper antibiotic therapyin patients with SIRS after PCNL.  Keywords: Percutaneous nephrolithotomy (PCNL), urine culture, stone culture, systemic inflammatory response syndrome after PCNL.

Abstract

Objective: To compare the efficacy of combination therapy of 4 mg doxazosin + 15 mg meloxicam with 4 mg doxazosin single therapy for benign prostate hyperplasia (BPH) patients with lower urinary tract symptoms (LUTS). Materials & Methods: A prospective, randomized and double blind study with total of 22 BPH patients with LUTS were randomized to receive 4 mg doxazosin + placebo once daily for 6 weeks or a combination of 4 mg doxazosin + 15 mg meloxicam once daily for 6 weeks. Inclusion criteria included IPSS ≥ 8, age > 50 years, prostate blood flow grade II. Therapeutic efficacy was assessed by comparing changes in IPSS, maximal urinary flow (Q-max) and changes in prostate blood flow between baseline and immediately after 6 weeks of therapy. Results: There was no significant difference in IPSS change between the two treatment groups (delta IPSS 4 ± 1.1 versus 3.7 ± 1.5, p = 0.630). There was a significant difference in Q-max changes between the two groups (delta Q-max 4 ± 1.5 versus 2.1 ± 0.7, p < 0.001). In group therapied with 4 mg doxazosin + 15 mg meloxicam prostate blood flow decreased from grade II to grade I in 9 of 11 patients (81%). Whereas, in the treatment group of 4 mg doxazosin + placebo no reduction was found in prostate blood flow. Conclusion: Combination therapy of 4 mg doxazosin + 15 mg meloxicam once daily for 6 weeks is better than 4 mg doxazosin therapy alone in improving Q-max and decreasing prostate blood flow in BPH patients with LUTS.Keywords: Benign prostate hyperplasia, inflammation, COX-2 inhibitors.
