Abstract
INTRODUCTION The purpose of our study was to evaluate the safety and efficacy of transcervical amnioinfusion during labour complicated by meconium-stained amniotic fluid, in a setting with limited peripartum facilities, to lower the incidence of caesarean section. METHODS A prospective study was conducted in a teaching hospital in north India, which enrolled 292 patients admitted in labour. Patients were randomly divided into two groups after taking their consent. One group received transcervical amnioinfusion, whilst in the other group amnioinfusion was not done. Caesarean sections were performed in either group if there were foetal heart rate abnormalities (bradycardia or irregularity for 10-20 min) or slow progress of labour. The outcomes studied were the incidence of caesarean sections, duration of maternal hospital stay, maternal febrile morbidity (temperature of >38 degrees C, 24 h after delivery), low Apgar score (at 1 and 5 min), respiratory death, MAS and perinatal mortality. RESULT There was a statistically significant reduction in the incidence of caesarean sections in the study group compared to the control group (31 vs. 61%). Amnioinfusion was associated with improved neonatal outcome as evidenced by statistically improved Apgar score at 1 min in newborns in the study group compared to the control group (10 vs. 37.2%). Amnioinfusion during labour was not associated with any significant maternal and neonatal complications. The mean hospital stay of the mother was decreased significantly in the study group patients compared to the control group. CONCLUSION Transcervical amnioinfusion in labour for meconium-stained amniotic fluid is a simple, safe and easy-to-perform procedure. It can be performed safely in a setup with limited peripartum facilities, especially in developing countries, to decrease intrapartum operative intervention and reduce foetomaternal morbidity and mortality.

Abstract
Background Endoglin (CD105) is a co-receptor for TGF-beta, is expressed by human vascular endothelial cells, and plays a major role in angiogenesis. Materials and methods Pretreatment EDTA plasma from 224 metastatic breast cancer patients enrolled in a phase III 2nd-line hormone therapy trial and 50 control subjects were assayed for endoglin using an ELISA. Results The female control group (n = 50) plasma endoglin upper limit of normal was defined as the mean + 2 SD (8.7 ng/ml). The breast cancer patient plasma endoglin was 6.40 +/- 2.23 ng/ml (range 3.00-19.79 ng/ml). Elevated plasma endoglin levels were detected in 26 of 224 patients (11.6%). Patients with elevated plasma endoglin had a reduced clinical benefit rate (CR + PR + Stable) (15 vs. 42%) (P = 0.01) to hormone therapy. TTP was shorter for patients with elevated plasma endoglin, but did not reach statistical significance (P = 0.2). Patients with elevated plasma endoglin had decreased overall survival (median 645 vs. 947 days) (P = 0.005). Conclusion Elevated pretreatment plasma endoglin levels predicted for decreased clinical benefit and a shorter overall survival in metastatic breast cancer patients treated with 2nd-line hormone therapy.

Abstract
AIMS The aim of the present study was to estimate the direct cost of treatment of diabetic foot ulcer at a tertiary care hospital in Karachi, Pakistan in order to assess the extent of the economic burden which it imposes. METHODS Out of 383 patients seen at Foot clinic of Baqai Institute of Diabetology and Endocrinology (BIDE), records of 214 patients were analyzed while 169 patients left against medical advice (LAMA). The UT system was used to classify ulcer types. Information was retrieved on resource consumption (physician services, chiropody, investigations, medicines, hospital care and surgical procedures). Interventions were summed and multiplied by the unit price of each resource, using charges levied at BIDE in the year 2005, in order to calculate the total cost of treatment. RESULTS 64% were male, with mean age 52.7 +/- 10.2 years. Mean duration of diabetes was 16.2 +/- 6.6 years. Majority (62.1%) were Grade 2 ulcer. The estimated direct cost of management increased from 2700 +/- 250 rupees (21 +/- 2 pounds) for a UT grade 1, stage B ulcer to 37,415 +/- 24,125 rupees (288 +/- 186 pounds) for UT grade 2, stage D and 49,058 +/- 30,144 rupees (378 +/- 232 pounds) for UT grade 3, stage D ulcers, respectively. The mean direct cost of major amputation (transtibial or transfemoral) was 46,182 +/- 30,742 ( 356 +/- 237 pounds) whilst the cost of a minor amputation was 50,494 +/- 30,488 rupees (389 +/- 235 pounds). CONCLUSIONS This retrospective study, despite having limitations, is important for a developing world country with limited data on health economics. Further larger scale prospective studies are needed to address this issue in more detail.

Abstract
INTRODUCTION In the military service, hearing is at risk through exposure to impulse noise from firing and detonations. This study aims at looking into the consequences of military training on hearing acuity, as it would be useful to confirm the effectiveness of the hearing conservation programme in the Singapore Armed Forces. METHODS A self-controlled study of 118 Singapore military conscripts was carried out, using questionnaires administered by trained personnel and pure tone audiometric assessments performed for both ears. The questionnaire and audiometry were done at the start of basic military training (BMT), with follow-up audiometry done at the end of BMT and one year into vocational military training (VT). RESULTS 33 military conscripts were excluded subsequently in latter phases of the study. Of the 85 remaining conscripts, 16.5 percent of the study population were found to have abnormal audiograms at the start of BMT. At the end of the BMT phase, the percentage of enlistees with abnormal audiograms was 9.4 percent. By the end of one year of VT, the percentage of enlistees with abnormal audiograms was still 9.4 percent. Analysis of the differences in number of enlistees with hearing loss was done with the McNemar's test, and was found to be statistically insignificant (p-value equals 0.238). CONCLUSION The prevalence of 16.5 percent abnormal audiograms at the pre-BMT stage is probably related to unfamiliarity with the audiogram testing and/or "temporary threshold shift" effect. There was no significant difference in the number of enlistees with hearing loss upon enlistment and after one year of military training in this cohort of soldiers.

Abstract
A redesigned motion control system for the medical robot Aesop allows automating and programming its movements. An IR eye tracking system has been integrated with this control interface to implement an intelligent, autonomous eye gaze-based laparoscopic positioning system. A laparoscopic camera held by Aesop can be moved based on the data from the eye tracking interface to keep the user's gaze point region at the center of a video feedback monitor. This system setup provides autonomous camera control that works around the surgeon, providing an optimal robotic camera platform.

Abstract
OBJECTIVES To establish the status of the deep veins in patients presenting with recurrent varicose veins and the effect on treatment decisions. DESIGN Retrospective clinical series. MATERIALS AND METHODS Duplex examination of 570 consecutive patients (843 limbs) presenting with recurrent varicose veins (CEAP C2-4). RESULTS Approximately one third of these patients (34.8%:294 limbs) had no deep venous abnormality; 173 limbs with superficial vein abnormalities only had great and/or small saphenous junction incompetence, the remaining 121 legs had abnormal perforating or communicating veins. Deep venous abnormalities were found in 549 limbs with evidence of persisting deep venous obstruction in only 20. Deep venous incompetence was found in 529 limbs (62.7% of all legs). However three segment incompetence (common femoral, femoral and popliteal veins) was found in only 181 legs (21.4%), two segment incompetence in 137 (16.2%) and one segment incompetence in 211 (25%). CONCLUSIONS Deep vein incompetence is common in patients with recurrent varicose veins. Deep venous obstruction is an infrequent finding but total deep venous reflux (three segment incompetence) affects just under one quarter of all limbs with recurrent varicose veins. Ablation or surgery of varicose veins in this group may be less effective. Patients should be advised of the implications of this finding.

Abstract
INTRODUCTION Since the discovery of Helicobacter pylori (H. pylori), much progress has been made worldwide in the field of its epidemiology. In spite of these advancements, many aspects of epidemiology still remain unclear, particularly among populations with low socio-economic status. The present study was designed to elucidate the different routes of transmission of H. pylori in the Hyderabad (South India) population and to investigate the impact of certain factors, such as age, gender, and lifestyle. METHODS Samples used for the study included saliva and biopsy samples of 400 symptomatic subjects from Hyderabad, India. The patients were retrospectively grouped, based on histopathology of the biopsy and 16S rRNA amplification of both saliva and biopsy as H. pylori positive and negative. RESULTS This study showed that the prevalence of H. pylori in both saliva and biopsy samples increased with age. In addition, the H. pylori infection was found more commonly in the saliva and biopsy samples among males (64 percent and 60 percent, respectively) than females (53.3 percent and 64 percent, respectively). Similarly, 71.6 percent and 73.5 percent of those who consumed municipal water acquired H. pylori (which were respectively found in their saliva and biopsy samples) compared to a lesser proportion (12.6 percent and 12.6 percent, respectively) of those who consumed boiled or filtered water. The study also found that subjects who preferred home-cooked food (57.1 percent and 57.7 percent) showed a lower prevalence of H. pylori in saliva and biopsy samples, respectively, compared to those (80 percent and 88 percent) who frequently ate out. CONCLUSION The results of the present study suggest that besides the oral-oral route, the transmission of H. pylori also takes place through the consumption of food prepared under unhygienic conditions. Consumption of municipal tap water also has a high impact in the transmission of H. pylori.

Abstract
INTRODUCTION Current guidelines that recommend Helicobacter pylori eradication treatment without endoscopy in selected patients underscore the importance of non-invasive testing. The accuracy of saliva as a non-invasive specimen was compared with that of invasive tests in pretreatment diagnosis of H. pylori infection. METHODS One hundred patients undergoing gastroscopy were grouped into 80 symptomatic and 20 asymptomatic subjects and were investigated for the presence of H. pylori in saliva and stomach. Samples tested comprised saliva and gastric biopsies collected from each patient. Exclusion criteria were history of peptic ulcer, bleeding ulcer, cancer or recent use of antibiotics, proton pump inhibitors and non-steroidal anti-inflammatory drugs. Two sets of primers homologous to 534 bp fragment of H. pylori DNA, which have been shown previously to be highly specific and sensitive, were used for the polymerase chain reaction (PCR) amplification. RESULTS 72 (90 percent) of the symptomatic group and 10 asymptomatic subjects were infected with H. pylori in the stomach as determined by histology and direct PCR amplification of biopsy DNA obtained from each subject. H. pylori DNA was identified in the saliva of 70 (87.5 percent) symptomatic subjects and 12 (60 percent) asymptomatic control subjects. CONCLUSION High rates of detection using saliva as a specimen indicate that saliva of the infected person could serve as a reliable non-invasive alternative to detect the presence of H. pylori infection in comparison to the currently available standard diagnostic tests.

Abstract
BACKGROUND There is significant heterogeneity in survival of patients with metastatic breast cancer who have bone-only metastasis. We studied the correlation of serum N-telopeptide (NTx), a marker of bone resorption, and its correlation with clinical outcomes in patients with metastatic breast cancer with bone-only or bone plus soft tissue metastasis. PATIENTS AND METHODS Serum was taken from 250 metastatic breast cancer patients with bone-only or bone plus soft tissue metastasis who participated in two similar randomized studies of second-line hormone therapy. An enzyme-linked immunosorbent assay specific for NTx of type I bone collagen was used to detect serum levels. RESULTS Sixty patients (24%) had elevated serum NTx levels, using the mean + 2 standard deviations (26 nanomoles Bone Collagen Equivalents per liter) of healthy women as a cut-off. The median duration of clinical benefit was significantly shorter in the group with elevated serum NTx levels compared with the group that had normal serum NTx levels (P=0.0004). Time to progression (TTP) was also significantly shorter in the patients with elevated serum NTx at 139 days compared with 220 days (P=0.0006). Median survival was also significantly shorter in patients with elevated baseline serum NTx levels at 663 days compared with 941 days (P<0.0001). CONCLUSION In this study, breast cancer patients with bone-only or bone plus soft tissue metastasis and elevated serum NTx levels have a shorter duration of clinical benefit, TTP and overall survival.

Abstract
OBJECTIVE To compare the efficacy of artemether and quinine in the treatment of severe malaria in hospitalized children. STUDY DESIGN Open randomized trial. SETTING Pediatric ward of a tertiary care center. METHODS All children admitted with clinical manifestations of severe malaria (as per WHO criteria) and asexual forms of Plasmodium falciparum demonstrated on peripheral smear were randomized to receive either artemether or quinine. Their clinical status and smears for parasite count were assessed every 12 hours until two successive blood films were negative. The primary end point of the study was death in the hospital and residual damage to the organ involved. The secondary end points were clearance of parasites and fever, length of time of recovery from coma and normal functions of the involved system. RESULTS Forty-six cases completed the study protocol, 23 assigned to each drug group. Cerebral malaria was the commonest manifestation (76.1%). Mean age in artemether versus quinine group (6.6 +/- 3.5 and 5.8 +/- 2.4 years) as well as degree of parasitemia at admission (55,800 and 60,300 per microlitre) were comparable. The overall mortality rate was 23.9% with no significant difference between the two groups. Twenty six cases (56.5%) presented with more than one manifestations of severe malaria. The mortality rate was 100% with four coexisting manifestations of severe malaria. Fever clearance time in artemether and quinine group was 44.5 and 45.9 hours respectively (P >0.05). Parasite clearance time was significantly shorter in artemether group (40.9 vs. 51.9 hours; P<0.001). Recovery from coma was shorter in artemether group (34.8 vs. 38.1 hours; P<0.05). CONCLUSION Cerebral malaria is the most common manifestation of severe malaria in children. Artemether is a good alternative drug to quinine for P. falciparum malaria. Mortality rate is directly proportional to the number of coexisting manifestations of severe malaria.

Abstract
AIM To determine the age, sex, and cause specific prevalences of blindness and visual impairment in adults 30 years of age and older in Bangladesh. METHODS A nationally representative sample of 12 782 adults 30 years of age and older was selected based on multistage, cluster random sampling with probability proportional to size procedures. The breakdown of the cluster sites was proportional to the rural/urban distribution of the national population. The examination protocol consisted of an interview, visual acuity (VA) testing, autorefraction, and optic disc examination on all subjects. Corrected VA retesting, cataract grading, and a dilated fundal examination were performed on all visually impaired subjects. The definitions of blindness (<3/60) and low vision (<6/12 to >or=3/60) were based on the presenting visual acuity in the better eye. The World Health Organization/Prevention of Blindness proforma and its classification system for identifying the main cause of low vision and blindness for each examined subject was used. RESULTS In total, 11 624 eligible subjects were examined (90.9% response rate) across the 154 cluster sites. A total of 162 people were bilaterally blind (1.53% age standardised prevalence) while a further 1608 subjects (13.8%) had low vision (<6/12 VA) binocularly. Visual acuity was >6/12 in the "better eye" in the remaining 9854 subjects (84.8%); however, 748 of these people had low vision in the fellow eye. The main causes of low vision were cataract (74.2%), refractive error (18.7%), and macular degeneration (1.9%). Cataract was the predominant cause (79.6%) of bilateral blindness followed by uncorrected aphakia (6.2%) and macular degeneration (3.1%). CONCLUSIONS There are an estimated 650 000 blind adults (95% CI 552 175 to 740 736) aged 30 and over in Bangladesh, the large majority of whom are suffering from operable cataract. This survey indicates the need for the development and implementation of a national plan for the delivery of effective eye care services, aimed principally at resolving the large cataract backlog and the inordinate burden of refractive error.

Abstract
AIM To evaluate the outcome of cataract surgery in the population of Bangladesh. METHODS Data were collected by the National Blindness and Low Vision Prevalence Survey of Bangladesh, a cross sectional, nationally representative sample (12 782 subjects) of the population aged >or=30 years. An interview recorded socioeconomic data. Each subject was tested for logMAR visual acuity (VA) of each eye, autorefracted, and then underwent optic disc examination. Those with <6/12 VA on presentation in either eye were retested with their refractive correction, dilated, and examined for anterior and posterior segment disease. In aphakic and pseudophakic subjects the date, location and operating conditions (eye camp/hospital), and type of operation(s) were recorded. RESULTS 11 624 eligible subjects were examined (90.9% response rate) in the survey. 162 subjects, 77 men and 85 women, had undergone cataract surgery in one or both eyes. 199 (88%) eyes had undergone intracapsular cataract extraction (ICCE), and 22 (10%) extracapsular surgery with intraocular lens (ECCE+IOL); surgical technique(s) in four cases were not identified. Presenting VA for the 226 operated eyes were: 68 eyes (30.1%) were 6/12 or better, 31 (13.7%) <6/12 >or=6/18, 63 (27.9%) 6/18 to 6/60, 8 (3.5%) <6/60 >or=3/60, and 56 (24.8%) <3/60. With "best" refractive correction these values were 114 (50.4%), 31 (13.7%), 51 (22.6%), 5 (2.2%), and 25 (11.1%), respectively. Of the 158 eyes with VA of 6/12 or worse on presentation, 44 (28%) were the result of coincident disease (principally age related macular degeneration), 95 (60%) refractive error (44 of these had uncorrected aphakia), and 19 (12%) operative complications. ICCE was more likely to result in a VA of <6/18 (OR: 4.26, p = 0.01) than ECCE+IOL. Likewise, eye camp surgery was more likely to result in a VA of <6/60 (OR: 1.98, p = 0.04). No significant association was found between time since surgery and VA outcome, nor was there a sex difference for postoperative vision. Literate subjects were significantly less likely to have an outcome of <6/18 (OR: 2.38, p <0.01) or <6/60 (OR: 2.87, p <0.01). Following ICCE (199 eyes), 56 (37%) of the 151 eyes with an aphakic spectacle correction achieved 6/12 or better. Females, eye camp surgeries, illiterate subjects, and rural dwellers were less likely to wear their aphakic correction. The ratio of ICCE:ECCE+IOL has reduced in the past 3 years (3.8:1) compared to >or=4 years before the survey (25:1). Hospital based ECCE+IOL surgeries were associated with a better outcome, yet 36% of these eyes were <6/12 postoperatively, after excluding coincident disease. CONCLUSION This evaluative research study into cataract surgery outcomes in Bangladesh highlights the need for an improvement in quality and increased quantity of surgery with a more balanced distribution of services.

Abstract
PURPOSE To determine the effect of elevated serum HER-2/neu on the response of metastatic breast cancer patients to an aromatase inhibitor versus an antiestrogen. PATIENTS AND METHODS Five hundred sixty-two estrogen receptor-positive metastatic breast cancer patients were randomized to first-line hormone therapy with either letrozole or tamoxifen. An automated enzyme-linked immunosorbent assay was used to detect serum HER-2/neu. RESULTS For patients with normal serum HER-2/neu (70.5%), objective response rate (ORR; 39% in letrozole-treated patients v 26% in tamoxifen-treated patients; P =.008), clinical benefit (CB; 57% v 45%; P =.016), time to progression (TTP; median, 12.2 v 8.5 months; P =.0019), and time to treatment failure (TTF; median, 11.6 v 6.2 months; P =.0066) were significantly better in patients treated with letrozole. In the elevated HER-2/neu group (29.5%), there was no significant difference in ORR (17% in letrozole-treated patients v 13% in tamoxifen-treated patients; P =.45) or CB (33% v 26%; P =.31), but there was a strong trend in favor of a longer TTP with letrozole (median, 6.1 v 3.3 months; P =.0596) and a significantly longer TTF with letrozole (median, 6.0 v 3.2 months; P =.0418). Multivariate analysis revealed that elevated serum HER-2/neu was a negative predictor for ORR and TTP. CONCLUSION Patients with normal serum HER-2/neu receiving letrozole demonstrated a significantly greater ORR and CB and longer TTP and TTF than patients receiving tamoxifen. Although in patients with elevated serum HER-2/neu there was no significant difference between letrozole and tamoxifen in ORR or CB, there was a strong trend favoring longer TTP and significantly longer TTF with letrozole.

Abstract
The authors use data from the 1990-1991 Pakistan Demographic and Health Survey to examine some variables indicating women's empowerment and to analyze the impact of such variables on reproductive choices. They conclude that "most Pakistani women are unaccustomed to the idea of planning children; for them, having children is a phenomenon as simple and common as most other issues of life. Among others who desire a specific number of children, the majority end up having more. It is because socio-cultural influences lead women to have a large family size. Our analysis also denotes similar results, and hence most of the empowerment variables used in this analysis do not explain the variation in the dependent variable as was expected." A comment by Khaleda Manzoor (pp.1,148-50) is included.

Abstract
PURPOSE To determine the effect of elevation of serum HER-2/neu on response to hormone therapy. PATIENTS AND METHODS Seven hundred nineteen metastatic patients with estrogen receptor-positive (ER(+)), progesterone receptor-positive, or both or ER status unknown breast cancer were randomized in three independent clinical trials to receive second-line hormone therapy with either megestrol acetate or an aromatase inhibitor (fadrozole or letrozole). An automated enzyme-linked immunosorbent assay specific for the extracellular domain of the HER-2/neu (c-erbB-2) oncoprotein product was used to detect serum levels. RESULTS Two hundred nineteen patients (30%) had elevated serum HER-2/neu protein levels, using the mean + 2 SD (15 ng/mL) from the serum of healthy women as an upper limit. Response to treatment was available for 711 patients. The response rate (complete responses plus partial responses plus stable disease) to endocrine therapy was 45% in 494 patients with non-elevated and 23% in 217 patients with elevated serum HER-2/neu levels (P <.0001). Median duration of treatment response (using the time to progression [TTP] variable for patients who responded) was shorter in the group with elevated serum HER-2/neu levels (11.7 months) compared with the patient group with non-elevated levels (17.4 months). TTP, time to treatment failure, and median survival (17.2 months v 29.6 months) were also significantly shorter in the patients with elevated serum HER-2/neu levels (P <.0001). CONCLUSION Patients with ER(+) and serum HER-2/neu-positive metastatic breast cancer are less likely to respond to hormone treatment and have a shorter duration of response than ER(+) and serum HER-2/neu-negative patients. Their survival duration is also shorter.
