RESUMO

Upper Gastrointestinal (GI) pseudomelanosis is an uncommon entity characterized by endoscopic visualization of speckled dark mucosal pigmentation. While described in the rectum and colon, 'melanosis' or more aptly 'pseudomelanosis' is rare in the duodenum and exceedingly rare in the stomach. Five cases of pseudomelanosis were encountered at our department. Four females and one male were diagnosed, with a mean age of 70 years. All patients exhibited duodenal pseudomelanosis, with one demonstrating gastric antral pseudomelanosis as well. Common features among these patients included iron deficiency anemia, hypertension, chronic kidney disease, hydralazine use and iron supplementation. Biopsy specimens stained at least partially positive for iron and stains for calcium and copper were negative. Histochemical analysis revealed the pigment of pseudomelanosis to be mainly iron sulfide, exhibiting unpredictable staining patterns, hypothesized to be secondary to varying sulfur content and iron oxidation. It is visualized as dark deposits in macrophages at the tips of the duodenal villi. Upper GI pseudomelanosis remains a poorly understood finding, weakly associated with chronic kidney disease, diabetes, hypertension, iron supplements and anti-hypertensive medications. While the pathogenesis, clinical and prognostic significance remains unclear, it is thus far considered a benign condition.

RESUMO

OBJECTIVE: To determine awareness of cancer risk factors in the patients and attendants of Out-patient Clinics at a University Hospital in Karachi, Pakistan. METHODS: A cross-sectional survey was conducted on 315 respondents reporting to a tertiary care hospital in Karachi, Pakistan, to assess their level of awareness regarding risk factors of cancer. RESULTS: The respondents belonged to an urban population with the mean time spent in Karachi of 29.1 years (SD +/- 13.94). There were 213 (67%) males and 102 (33%) females. All respondents had heard of the word 'cancer', while only 57.5% were aware of cancer risk factors. However, only 42.8% could identify age, 33% diet, 35% drugs and 31% obesity as risk factors for cancer. Even those who were aware of the risk factors were not able to appreciate personal risk of cancer. CONCLUSION: Despite awareness regarding some of the risk factors, the surveyed population was not aware of intrinsic risk factors for cancers like increasing age and obesity. It is important to create awareness through educational programs on cancer prevention, dissemination of knowledge pertaining to the preventable and avoidable cancer risk factors, the benefits of early diagnosis, and availability of screening tests.

RESUMO

OBJECTIVE: To evaluate how the implementation of universally acceptable standards affects rates for primary caesarean sections, without compromising maternal or foetal safety. METHODS: A complete audit cycle of all the primary caesarean sections performed in the maternity unit of Aga Khan University was conducted from 1st January to 31st March during years 2003 and 2004. New labour management guidelines were implemented after the first audit (appendix). The rates of caesarean section, induction of labour, failed induction, and maternal and foetal outcomes were compared before and after the implementation of the guidelines. RESULTS: Primary emergency caesarean section rate decreased from 16% to 12%. A reduction in primary caesarean sections was noted in the induced cases. Practice of checking cord blood for foetal pH and maintaining partograms improved markedly. There were no significant adverse maternal and perinatal outcomes. CONCLUSION: Implementation of standard labour management strategies can reduce primary caesarean section rate without compromising maternal and foetal safety.

RESUMO

OBJECTIVE: Provide an overview of the demographics and pathology of breast cancer in the female population of Karachi South during a 3 year period, 1995-1997. METHODS: Epidemiological data for 709 incident breast cancer cases, ICD-10 category C50 registered at Karachi Cancer Registry during 1st January 1995 to 31st December 1997 were reviewed. RESULTS: Breast cancer accounted for approximately one-third of the cancers in females. The age standardized incidence rate (ASR) world per 100,000 was 53.8, the crude incidence rate was 30.9. In KS 60% of the newly diagnosed breast cancers were observed in women below 50 years. The age-specific curves showed a gradual increase in risk from the third up till the seventh decade, followed by an actual/apparent decrease in risk. The socio-economic distribution was 24.9% in category I the financially deprived class, 38.9% in category II the middle class and 35.9% in category III, the affluent class. Microscopic confirmation of malignancies was 99%. Invasive breast cancers predominated with 99.4%, with in-situ cancers contributing to 0.6% of the malignancies. The morphology of cancers was tilted towards duct cell carcinoma (DCC), pure DCC (92%), combinations of DCC /Paget's disease (0.6%) and lobular carcinoma (0.4%). Approximately 45% of duct cell carcinoma were seen in the premenopausal age group (<45 years). All bilateral breast cancers were duct cell carcinoma with a family history of first degree relative with breast cancer. The majority of the cases presented as moderately differentiated or grade 2 lesions (59.0%). Approximately 56% cancers had spread to the regional lymph nodes and 8.3% to a distant site at the time of diagnosis. A family history of first degree relative with breast cancer was present in 3% and second degree relatives in 7% of the cases. Odds ratio (OR) for 680 breast cancer cases with complete demographic information was calculated with 675 gender matched controls. A slightly higher risk was observed in non-Muslims and migrant ethnicities: two to three fold elevation in the Indian migrants (Gujrati speaking Mohajirs OR 3.86 (95% CI 2.51; 5.92) Urdu speaking Mohajirs OR 2.85 (95% CI 2.05; 3.96), Memon Mohajirs OR 2.21 (95% CI 1.48; 3.29) and Afghan migrants [OR 2.99 (95% CI 11.20; 7.44)]. The risk was also high in the females of Punjabi ethnicity settled in KS [OR 2.73 (95% CI 1.87; 3.99)]. The risk seems much less for the ethnicities belonging to North Western Pakistan i.e. Pathans [OR 1.684 (95% CI 0.89; 3.17)] and Baluchs [OR 0.90 (95% CI 0.58; 1.39)]. A marginally higher risk was observed in the higher socio-economic categories. The risk of developing breast cancer increased gradually for each age category from illiterate [OR 1.2 (95% CI 0.94; 1.55)] to college graduates [OR 13.12 (95% CI 7.31; 23.73)]. CONCLUSIONS: The incidence of breast cancer in Karachi South (KS) for the period 1995-1997 was the third highest in Asia. The hallmarks were a high reproductive age malignancy involving a higher socio-economic class, an invasive duct cell carcinoma diagnosed at an advanced stage, in younger more educated females and a low in-situ malignancy. More studies are required to obtain a deeper insight into this breast cancer epidemic in Karachi. Implementation of breast cancer screening with stress on public health education is today a major responsibility of the government.

RESUMO

INTRODUCTION: The present study was conducted with the objective of examining descriptive epidemiological and pathological characteristics of cancer cervix in Karachi South, an all urban district population of Karachi, Pakistan. METHODOLOGY: A total of 74 cases of cancer cervix, ICD-10 (International Classification of Diseases 10th Revision) category C53 were registered at the Karachi Cancer Registry, for Karachi South, during a 3 year period, 1st January, 1995 to 31st December 1997. RESULTS: The age standardized incidence rate (ASR) world and crude incidence rate (CIR) per 100,000 were 6.81 (5.2, 8.43) and 3.22 (2.49 to 3.96). Cancer cervix accounted for approximately 3.6% of all cancers in females and was the sixth malignancy in hierarchy. The mean age of the cancer cases was 53.27 years [standard deviation (SD) 11.6; 95% confidence interval (CI) 50.58, 55.96; range (R) 32-85 years)]. The distribution by religion was Muslims (90.5%), Christians (8.1%) and Hindus (1.4%). There were no cases reported in Parsees. The frequency distribution by ethnicity was Urdu speaking Mohajirs (20.3%), Punjabis (17.6%), Gujrati speaking Mohajirs (4.1%), memon Mohajirs (8.1%), Sindhis (10.8%), Baluchs (8.1%), Pathans (5.4%) and Afghan migrants (2.7%). The ethnicity was not known in approximately a fourth (23.0%) of the cases. The socio-economic distribution was 27.0% financially deprived class, 24.4% lower middle class and 48.7% upper middle and affluent classes. The majority of the women were married (86.5%); a smaller number were unmarried (2.7%) or widows (10.8%). The age-specific curves showed a gradual increase in risk from the fourth up till the seventh decade, followed by an actual apparent decrease in risk after 64 years of age. The peak incidence was observed in the 60-64 year age group. The morphological categorization was squamous cell carcinoma (86.5%), adenocarcinoma (10.9%) and adenosquamous carcinoma (2.6%). The majority of cases presented with moderately differentiated or grade 2 lesions (45.9%). There were no in-situ cases. Approximately half the cancers (58.1%) had spread regionally and 8.1% to a distant site at the time of diagnosis. Odds ratios (OR) were calculated for socioeconomic residential categories, religion, ethnicity, age groups and education. The OR for socioeconomic residential categories ranged between 0.69 and 2.9 with a marginally higher risk in the lower [OR 2.09 (95% CI .97; 4.49)] and lower middle class [OR 2.08 (95%CI 0.95; 4.58)]. Hindus [OR 1.2 (95% CI 0.18; 2.2)] had a slightly higher risk then the Muslims [OR 0.14 (95% CI 0.17; 1.2)]. A higher risk was also observed for Christians [OR 7.76 (95% CI 1.74; 34.5)]. CONCLUSION: The incidence of cervical cancer in Karachi South (1995-97) reflects a low risk population with a late presentation and a high stage disease at presentation. It is suggested that cervical screening if implemented should focus on once a life time methodology involving 36-45 year old women. This should be combined with HPV vaccination for the young and public health education for all. A regular cervical screening program would require mobilization of considerable financial, structural and human resources along with training for personnel. This may burden the already stretched health resources of a developing country.

RESUMO

The month of March is dedicated to Colon Cancer Awareness. Worldwide, colorectal cancer (CRC) incidence has been on the rise. It is currently the third most common cancer in men (746,000 cases, 10.0% of the total) and the second in women (614,000 cases, 9.2% of the total).1 Arecent meta-analysis reported a 61% risk reduction in CRC incidence with colonoscopy.2 Unlike screening programs for breast and prostate cancers, not only has CRC screening reduced mortality from colon cancer and detected early CRC, it has also decreased the incidence of CRC through detection and removal of pre-cancerous lesions. Studies have shown that screening for colorectal cancer provided 152 to 313 life-years-gained (LYG) per 1000 forty-year-old individuals.3 Anumber of modalities exist for CRC screening, which can broadly be categorized into stool-based tests and direct visualization tests. Stool-based tests include fecal occult blood testing (FOBT), fecal immunochemical testing (FIT) and stool DNAtesting. Direct visualization tests include endoscopic procedures such as colonoscopy and flexible sigmoidoscopy; and radiographic tests such as CT colonography, which has largely replaced air contrast barium enemas.4 The only reported population-based data for CRC in Pakistan comes from Bhurgri et al. in 2011.5It described Pakistan as a low risk region with an age standardized incidence rate (ASR) world per 100,000 of 7.1 in males and 5.2 in females, but with a much younger age and advanced stage at diagnosis. The ratio for individuals diagnosed with CRC under the age of 40, as oppose to over 40 years, was 3:1, which is much higher than the international average. Noteworthy as well, is an increase in incidence especially among men, noted between the study periods of 1995-1997 and 1997-2002. It ranks 7th in incidence among males, and 8th among females, with tobacco related malignancies topping the list.6 There has since been additional cross-sectional data from Pakistan echoing these findings of a younger age and advanced disease at presentation.7 Speaking from a public health perspective, Pakistan, while still battling communicable diseases, is now seeing an increasing incidence of non-communicable diseases population-based screening programs for CRC were not justified in most developing countries, citing low reported incidence and low resource health authorities; but that in limited regions with an ageing population and a shift to Western lifestyle, organized screening strategies needed to be developed. This can well be extrapolated to large urban centers in Pakistan. In a resource poor, conservative country like Pakistan, with poor health literacy, there exist many barriers to CRC screening which were summed up very articulately by Ahmed F in 2013. Quite appropriately, areas identified for further pursuit included, among others, the training of gastroenterologists, especially female ones, less expensive and more culturally acceptable screening options, and cost-effectiveness analyses. The recipe for any cancer screening program to be successful, begins with epidemiological data to document disease burden. There has not been any population-based cancer registry to report incidence data for the past few years. There is also no centralized cancer registry to effectively unify and coordinate data from across the country. Furthermore, even with a cancer registry there is no mandated reporting of malignancies from a health policy standpoint, as exists in the more developed world. The last population-based data we have for CRC was for cases reported until 2002, and there was already an increase in incidence noted in less than a decade, starting in 1995.5 Health awareness is another important factor. There is no data from Pakistan regarding patient or physician awareness regarding colon cancer. If one is to extrapolate, a cross-sectional study on breast cancer awareness, for which Pakistan demonstrates one of the highest incidences worldwide,6 reported that a mammogram had been performed in only 4.9 % of women in the cohort, while 61.5 % of the remainder had never even heard about it.7 It is also unclear if we have the infrastructure including endoscopy centers and adequate numbers of gastroenterologists to service the population at large. FOBTis available and cheap, but there is no data regarding the availability of FITor stool DNAtesting. In the absence of health insurance, it will certainly be a challenge to make CRC screening widely accessible. At what point does a disease warrant attention? While we may not have the luxury or the immediate necessity to introduce mass population-based CRC screening, we can certainly start with individual screening in populations who are at high risk of colorectal cancer due to family history and have adequate access to healthcare. There should be a concerted drive to revitalize cancer registration in order to guide health policy and to have an effective national cancer control program. Awareness programs are also needed to be established for the public and, specifically, for physicians as well.

RESUMO

Eosinophilic gastrointestinal disorders represent a spectrum of disorders demonstrating gastrointestinal eosinophilia without any known cause for eosinophilia. Pathogenesis is not clearly established, but immune responses to dietary antigens are implicated. These disorders affect children and adults and are seen in association with allergic disorders. Eosinophilic esophagitis is diagnosed in the setting of mucosal eosinophilia on endoscopic biopsy and symptoms of esophageal dysfunction. Eosinophilic gastroenteritis is also diagnosed with endoscopic biopsies. Eosinophilic colitis commonly presents with lower gastrointestinal symptoms and is a diagnosis of exclusion.

RESUMO

A growing body of evidence suggests that oxygen radicals can mediate myocardial tissue injury during ischaemia and, in particular, during reperfusion. This review focuses on the role of neutrophil as a mediator of myocardial damage. Upon reperfusion, neutrophils accumulate and produce an inflammatory response in the myocardium that is responsible, in part, for the extension of tissue injury associated with reperfusion. It has shown that the inhibition of neutrophil accumulation and adhesion is associated with decreased infarct size. This strongly suggests that myocardial cells at risk region undergo irreversible changes upon reperfusion and accumulation of neutrophils. Several pharmacological agents (ibuprofen, allopurinol, prostacyclin, and prostaglandin E analogues) protect the myocardium from reperfusion injury. In addition, the mechanisms by which these agents act and directions of research that may lead to therapeutically useful approaches are also discussed in this review.

RESUMO

The study was conducted with the objective of examining descriptive epidemiological characteristics of malignant ocular tumours in Karachi (1998-2002). The data for two hundred and forty two ocular malignancies registered at the Karachi Cancer Registry for Karachi Division during a 5-year period, from January 1(st) 1998 to December 31(st) 2002 were analysed. The age standardized incidence rate (ASIR) was 0.5/100,000 in males and 0.4/100,000 in females. The gender ratio (M:F) was 1.3. The mean age was 34.8 years (95% CI 30.1; 39.6) in males and 34.5 years (95% CI 28.0; 40.9) in females. A fourth of the malignancies were childhood tumours. The most common childhood malignancies were retinoblastomas and rhabdomyosarcomas, whereas the most common adult malignancies were conjunctival squamous cell carcinomas and melanomas. Approximately 97.0% of the tumours were histologically confirmed. The majority (62.5%) presented as low-grade (grade 1) lesions, and were localized to the eye (50%) at the time of diagnosis. The annual incidence rates remained stable during this period. The crucial importance of ocular malignancies is the high 5-year survival rates, associated disability following unilateral or bilateral enucleation and the implications as preventable components of Cancer Control Programs This article provides demographic statistics, which could be useful for the foundation, establishment and monitoring of a component of an effective cancer control program, the risk factors of ocular malignancies being well established. It is recommended that public health education to prevent ultraviolet light related ocular malignancies, information on preventative sun protection behavior, legislation for occupation related ocular cancers and genetic counseling for familial retinoblastoma should be essential primary components of all National Cancer Control Programs even in apparently low risk countries. In the long-term perspective, these efforts should further reduce the incidence - meanwhile stabilization of incidence rates could be achieved. Early detection and standardized treatment will reduce the associated morbidity and mortality.

RESUMO

The epidemiological features of rhabdomyosarcoma (RMS), an uncommon malignancy composed of cells with histopathologic features of striated muscle, were studied in Pakistan. Incident RMS cases recorded at the Karachi Cancer Registry during 1998 to 2004 were reviewed and to ensure maximum completeness of data, only those registered between 1998 and 2002 were considered for the present study. Two hundred and seventeen cases were reported to the Karachi Cancer Registry during this five-year period. One hundred and forty eight of the patients (60.4% males; 39.6% females) were residents of Karachi. The crude and standardized annual incidence rates/100,000 were 0.3 for males and 0.2 for females. The incidence was 0.5 in children below 15 years of age. The primary RMS sites in males were head and neck (28.1%), extremities (25.8%), genitourinary (GU) tract (17.9%), trunk (9.0%), orbit (7.9%), and retroperitoneum (3.4%). RMS occurred at other sites in 7.9% of the patients. Corresponding frequencies in females were head and neck (35.6%), extremities (16.9%), GU tract (16.9%), trunk (8.5%), orbit (8.5%) and other sites in 13.6%. Approximately 60% of the cases were childhood RMS and three fourths were below 21 years. The mean age of RMS cases all sites, males, was 18.5 years (95% CI 15.6; 21.4); for childhood RMS, 7.5 years (95% CI 6.0; 9.2); and for adult RMS 34.2 years (95% CI 28.3;40.2). In females, the corresponding figures were 18.2 (95% CI 13.7; 22.7); 6.6 (95% CI 5.0; 8.1) and 33.9 (95% CI 27.5; 40.5), respectively. One hundred cases were retraceable, and the mean survival time, RMS all sites and ages in both genders, was 1.5 years (95% CI 1.1; 1.9). The 5-year survival was 10%, and 3-year survival was 30% whereas 16.7% of the patients died within a year of diagnosis. The indicators of poor prognosis, a late presentation, rapid evolution, advanced disease, tumor burden (tumor size >5.cms) and regional lymph node involvement, are characteristic of RMS in Karachi. Recent advances in RMS multimodality treatment protocols have improved RMS prognosis in patients with limited disease. Pakistan should focus on early diagnosis and prompt treatment of malignancies. This requires health education for the general population to create awareness and training of health professionals at all levels to promote early diagnosis. An RMS group is required, which would monitor the treatment, recurrence, patient education and provide psychosocial support. Cytogenetic studies are advised for a better understanding of biologic differences in RMS cases in this population.

RESUMO

The objective was to assess epidemiologic aspects of retinoblastoma development in Karachi, Pakistan. Incident cases, diagnosed clinically or microscopically and registered at Karachi Cancer Registry (KCR) during 1(st)January 1998 to 31(st) December 2002 were reabstracted, rechecked and reanalyzed for this purpose. One hundred and one cases of retinoblastoma were reported to KCR over the 5 years (1998-2002). Fifty-seven were residents of Karachi, 34 (59.6%) males and 23 (40.4%) females. The gender ratio (M:F) was 1.5. The mean age at diagnosis was 3.96 years (95% CI 2.92; 4.99) and 3.85 years (95% CI 2.72; 4.98) in males and females respectively. The annual crude incidence of retinoblastomas in Karachi was 4.0/100,000 and 2.4/100,000 in children under the age of 5 and 10 years respectively, the corresponding age standardized rates being 5.3/100,000 and 4.8/100,000. The age groups at risk of developing retinoblastoma, associated morbidity and possibility of almost 100% 5-year survival with available treatments, calls for ophthalmologic screening of all infants below 1 year, and high-risk children until the age of 7 years. In order to detect retinoblastoma, as early as possible, health education for parents and health providers, and improved training of ophthalmologists is essential. Genetic testing for siblings and children of retinoblastoma cases and identification of high-risk children would be helpful, but lacks financial feasibility in developing countries at present. Future health care planning should focus on capacity building for neonatal ophthalmologic screening, handling of parents'and children'emotional reactions and opportunities for education, occupational training and cosmetic rehabilitation for surviving retinoblastoma patients.

RESUMO

OBJECTIVE: To study the differences in the incidence of cancer esophagus in Karachi and Quetta, Pakistan. METHODS: Incident cases of cancer esophagus registered from January 1, 1995 to December 31, 2000 were included for Karachi South, and those registered from January 1, 1998 to December 31, 2000 were included for Karachi Division and Quetta. RESULTS: In Quetta, cancer esophagus had age-standardized incidence rate (ASIR) of 25.5/100,000 population in males and 23.4/100,000 population in females, and it was the commonest malignancy in both genders. In comparison, in Karachi South and Karachi Division, cancer esophagus ranked 7th among cancers in males (ASIR 6.2/100,000 and 5.0/100,000 population, respectively) and 5th in females (7.0/100,000 and 4.9/100,000 population, respectively). The ASIR was similar among males and females in all data sets. CONCLUSION: The incidence of cancer esophagus in Quetta is comparable to that in high-incidence regions, whereas the incidence in Karachi is similar to that in moderate-incidence zones. In contrast to other world regions, cancer esophagus was equally common in males and females in Pakistan. The high risk in Quetta warrants investigation for risk factors and a targeted cancer control program.

RESUMO

A 60-year-old man underwent surveillance colonoscopy that demonstrated five subcentimetre polyps, all of which were biopsied. One of the five polyps had histopathology consistent with small cell lung carcinoma (SCLC) metastasis from primary lung cancer. Subsequent imaging demonstrated a spiculated mass in the right upper lung lobe with metastasis to the brain, liver and spleen. He was immediately treated with palliative whole-brain irradiation followed by eight cycles of carboplatin and etoposide. Despite aggressive management, he had disease progression characterised by worsening performance status and development of transfusion-dependent anaemia, new blastic bone lesions and epidural disease. Given his liver failure, he was not considered a candidate for second-line topotecan. After discussion with the patient, family and palliative services, he was discharged with home hospice. This report describes a rare case of advanced SCLC presenting as a metastatic caecal polyp on surveillance colonoscopy.

RESUMO

INTRODUCTION: This study was conducted to assess the patterns of primary central nervous system (CNS) malignancies in Karachi South (KS), a moderate risk population in Asia. MATERIALS AND METHODS: Data for 321 registered cases were reviewed and analyzed in two periods 1995-1997 (111 cases, 75 (67.6%) male (M); 36 (32.4%) female (F)) and 1998-2002 (210 cases, 124 (59.1%) M; 86 (40.9%) F). RESULTS: Age standardized incidence rate per 100,000, crude incidence rate and relative frequency in 1995-1997 were 3.5, 2.8 and 3.5% (M) and 1.8, 1.6 and 1.7% (F). Corresponding figures for 1998-2002 were 3.3, 2.7 and 2.7% (M) and 3.3, 2.7 and 2.1% (F). Mean age of male and female patients during 1995-1997 was 33.3 years (SD± 20.4) and 30.7 years (SD±19.6). Mean ages for 1998-2002 were 33.2 years (SD±19.5) and 28.7 years (SD±18.5) for males and females respectively. In males, 199 malignancies were reported, 106 (86.9%) cases in the brain, 10 (5.5%) in meninges and 12 (6.0%) in the spinal cord; 122 cases were observed in females, 177 (89%) cases in the brain, 8 (6.6%) each in the meninges and spinal cord. The most common morphology was astrocytoma (72 (36.2%) (M); 40 (32.7%) (F)). Mean age of low grade astrocytoma was 27.8 years (M) and 27.0 years (F); anaplastic astrocytomas, 40.5 years (M), 34.1 years (F) and glioblastoma, 45.7 years (M) and 38.3 years (F). Youngest cases were registered for cerebellum and brain stem. CONCLUSION: The incidence of CNS malignancies is stable in males and gradually increasing in females. Astrocytoma is the commonest morphology; they affect a younger age group and show an age gradient in proportion to tumor grade. The mean age varied by sub-site and histology. Focus should be directed towards the understanding the biological nature and risk factors prevalent in this population.
