RESUMEN

The message that health care providers caring for patients with breast cancer would like to put forth, is that, not only early detection is crucial but early treatment too is important in ensuring survival. This paper examines the pattern of presentation at a single institution over a 10-year period from 1995 to 2005. In Malaysia, education outreach programmes are ongoing, with contributions not only from the public sector, but also private enterprise. Articles on breast cancer in local newspapers and women magazines and television are quite commonplace. However are our women getting the right message? Now is an appropriate time to bring the stakeholders together to formulate a way to reach all women in Malaysia, not excluding the fact that we are from different races, different education levels and backgrounds requiring differing ways of delivering health promotion messages. To answer the question of why women present late, we prospectively studied 25 women who presented with locally advanced disease. A quantitative, quasi-qualitative study was embarked upon, as a prelude to a more detailed study. Reasons for presenting late were recorded. We also looked at the pattern of presentation of breast lumps in women to our breast clinic in UMMC and in the surgical clinic in Hospital Kota Bharu, in the smaller capital of the state of Kelantan, in 2003. There is hope for the future, the government being a socially responsible one is currently making efforts towards mammographic screening in Malaysia. However understanding of the disease, acceptance of medical treatment and providing resources is imperative to ensure that health behaviour exhibited by our women is not self-destructive but self-preserving. Women are an integral part of not only the nation's workforce but the lifeline of the family - hopefully in the next decade we will see great improvement in the survival of Malaysian women with breast cancer.

RESUMEN

PURPOSE: To evaluate the efficacy of adjuvant intravesical doxorubicin in superficial transitional cell carcinoma of the urinary bladder on long-term follow-up. MATERIALS AND METHODS: Between July 1986 and November 1991, all patients harboring superficial bladder cancers (Ta or T1) with one or more of these criteria (stage > a, grade > 1, size > 1 cm, multiple or recurrent tumors) were randomized to receive either 50 mg doxorubicin or no adjuvant therapy. Patients with recurrences were allowed to receive doxorubicin or other intravesical agents. Recurrence, progression and survival were analyzed. RESULTS: There were 82 patients included (64 males and 18 females). The mean age was 64 years. Forty-six patients were randomized to the doxorubicin group and 36 to the control group. Final analysis was made at median follow-up of 45, 128 and 131.5 months for recurrence, progression and survival, respectively. Recurrence free, progression free and disease specific survival did not differ significantly between groups. The 10-year Kaplan-Meier estimates for recurrence free, progression free and disease specific survival were 67 percent, 84 percent and 92 percent, respectively for the doxorubicin group, and were 50 percent, 89 percent and 97 percent, respectively for the control group. Tumor size predicted recurrence (p = 0.013) and grade predicted progression (p = 0.004) with multivariate analysis. CONCLUSIONS: Adjuvant intravesical doxorubicin could not be shown to improve recurrence, progression and survival of superficial bladder cancer, compared with control on long-term follow-up. Tumor size and grade were shown to be prognostic factors for recurrence and progression, respectively.

RESUMEN

PURPOSE: We investigate the use of non-contrast helical computerized tomography (NCHCT) in the measurement of differential renal parenchymal volume as a surrogate for differential creatinine clearance (CrCl) for unilateral chronically obstructed kidney. MATERIALS AND METHODS: Patients with unilateral chronically obstructed kidneys with normal contralateral kidneys were enrolled. Ultrasonography (USG) of the kidneys was first done with the cortical thickness of the site with the most renal substance in the upper pole, mid-kidney, and lower pole of both kidneys were measured, and the mean cortical thickness of each kidney was calculated. NCHCT was subsequently performed for each patient. The CT images were individually reviewed with the area of renal parenchyma measured for each kidney. Then the volume of the slices was summated to give the renal parenchymal volume of both the obstructed and normal kidneys. Finally, a percutaneous nephrostomy (PCN) was inserted to the obstructed kidney, and CrCl of both the obstructed kidney (PCN urine) and the normal side (voided urine) were measured two 2 after the relief of obstruction. RESULTS: From March 1999 to February 2001, thirty patients were enrolled into the study. Ninety percent of them had ureteral calculi. The differential CrCl of the obstructed kidney ( percentCrCl) was defined as the percentage of CrCl of the obstructed kidney as of the total CrCl, measured 2 weeks after relief of obstruction. The differential renal parenchymal volume of the obstructed kidney ( percentCTvol) was the percentage of renal parenchymal volume as of the total parenchymal volume. The differential USG cortical thickness of the obstructed kidney ( percentUSGcort) was the percentage of mean cortical thickness as of the total mean cortical thickness. The Pearson's correlation coefficient (r) between percentCTvol and percentCrCl and that between percentUSGcort and percentCrCl were 0.756 and 0.543 respectively. The regression line was percentCrCl = (1.00) x percentCTvol - 14.27. The percentCTvol overestimated the differential creatinine clearance by about 14 percent, but the correlation is good. CONCLUSION: The differential renal parenchymal volume measured by NCHCT provided a reasonable prediction of differential creatinine clearance in chronically obstructed kidneys.

RESUMEN

The immunogenicity and reactogenicity of an inactivated hepatitis A virus (HAV) vaccine was studied in healthy Singaporean adult volunteers. One hundred and forty healthy volunteers with normal alanine (ALT) and aspartate (AST) transaminases and no previous exposure to HAV, received three 1 ml doses (720 ELISA units) of an inactivated HAV vaccine (Smithkline Beechams Biologicals) following a 0, 1, 6 months vaccination schedule. All subjects were asked to record and grade the severity of any reactions for three consecutive days after each dose. Serum ALT and AST as well as anti-HAV were measured at 0, 1, 2, 6 and 7 months after the first vaccine dose. Anti-HAV seroconversion occurred when levels rose above 40 mIU/ml. Eighty-five percent of vaccinees seroconverted after the first innoculation and 99% after the second injection. All vaccinees seroconverted after the third dose. Geometric mean anti-HAV titers (GMTs) were, respectively, 119, 391, 4406 mIU/ml one month after each of the three doses. The most common side effect was transient pain and tenderness at the vaccination site. No elevation of ALT or AST levels were noted during the study period. The inactivated hepatitis A vaccine used in this study is safe and highly immunogenic in the local adult population. Two doses one month apart appeared to give adequate protection.
