Abstract
BACKGROUND Current amblyopia screening methods are not cost effective. AIM To evaluate the diagnostic capability of a modified Brückner test (MBT) for amblyopiogenic risk factors. MATERIALS AND METHODS We applied the MBT using the streak retinoscope to identify anisometropia and strabismus by noting an inter-ocular difference in movement and glow, from children who failed 6/9 Snellen on community vision screening, followed by comprehensive eye examination. STATISITICS: Data were analyzed by 2 × 2 tables for diagnostic test parameters (95% CI). RESULTS From 7998 children vision-screened, 392 failed 6/9 VA and were referred. Since 34 failed to reach the centers, and 15 were excluded due to poor/ no glow, data from 343 was analyzed. The prevalence of anisometropia of 0.5D was 17%, of 1D was 11% and of strabismus 5%. For the MBT the accuracy was ≥ 90% (95%CI 89% to 97%) over the three outcomes. The sensitivity, specificity, NPV and +LR for anisometropia of 0.5D were: 0.57 (0.48, 0.64), 0.97 (0.95, 0.98), 0.92 (0.90, 0.93) and 18 (9.7, 35); for 1D: 0.74(0.60, 0.82), 0.95 (0.94, 0.97), 0.97 (0.95, 0.98) and 16 (9.3, 28); and for strabismus: 0.5 (0.32, 0.66), 0.98 (0.97, 0.98), 0.97 (0.96, 0.98) and 20 (9.1, 42). CONCLUSION Our data suggests that the MBT is highly accurate and useful for ruling in anisometropia and strabismus in children who fail 6/9 Snellen. The MBT needs further validation, both by different care givers and on differing populations. It offers an affordable, portable, and clinically useful tool to detect anisometropia and strabismus. We suggest that performing an MBT prior to uniocular retinosocpy should be a routine practice.

Abstract
The present study deals with the evaluation of the efficacy of oxaliplatin and paclitaxel combination as a potential strategy in controlling HNSCC cell proliferation and the assessment of correlation between occurrence of apoptosis and changes in expression of survivin (IAP). The panel cell lines included two HNSCC cell lines (Cal27 and NT8e) and one normal cell line (293) with differential level of survivin expression in accordance with chemosensitivity. The cytotoxicity and effect of drugs on apoptosis was determined, separately and in combination. Combined treatment of cells with paclitaxel and oxaliplatin resulted in significantly higher cytotoxicity as compared to individual single drug treatment. Cytotoxicity was prominent in paclitaxel to oxaliplatin (pacl-oxal) sequence treatment with an approximate two-fold increase in apoptosis as compared to oxaliplatin to paclitaxel (oxal-pacl) sequence treatment. Paclitaxel treatment also caused increased survivin expression showing reduced apoptosis at low concentration. Oxaliplatin, when combined with paclitaxel, decreased the survivin level with increased cell death. Inhibition of survivin by a small interfering RNA (siRNA) method also increased the sensitivity of the cancer cell lines to paclitaxel whereas over-expression of survivin in the transfected 293-cell line provided resistance. In conclusion, the interaction between drugs was synergistic and schedule-dependent. Survivin played a critical role in paclitaxel resistance through the suppression of apoptosis, and a significant induction of apoptosis was observed when oxaliplatin was combined with paclitaxel at least in part by the down-regulation of survivin.

Abstract
In vitro susceptibility of 141 clinical isolates of Candida species to caspofungin and anidulafungin is reported. the Etest was performed according to recommended procedure and minimum inhibitory concentrations (MICs) were read after 24 h of incubation at 35 °C. Applying a breakpoint of <2 mg/ml, all Candida spp. isolates, except those belonging to C. parapsilosis complex, were susceptible. The geometric mean for caspofungin and anidulafungin for different Candida spp. were as follows: Candida parapsilosis, 0.438 and 3.355 μg/ml; Candida orthopsilosis, 0.210 and 1.456 μg/ml; Candida albicans, 0.049 and 0.007 μg/ml; Candida dubliniensis, 0.077 and 0.009 μg/ml; Candida tropicalis, 0.061 and 0.027 μg/ml; Candida glabrata, 0.120 and 0.032 μg/ml; and Candida krusei, 0.288 and 0.052 μg/ml, respectively. Anidulafungin was significantly more active than caspofungin (p <0.001) except for C. parapsilosis complex spp. isolates. In conclusion, our Etest MICs compared well with epidemiological cutoff values derived from a large number of Candida spp. isolates tested by CLSI method in previous studies. However, considering the differences in MICs of the two echinocandins for C. parapsilosis complex isolates, the Etest needs further evaluation for its suitability.

Abstract
BACKGROUND Infant mortality rate is regarded as an important and sensitive indicator of the health status of a community. It also reflects the living standard of the people and the effectiveness of interventions for improving maternal and child health. Multiple factors related to social and economic conditions, health care and environment have a significant role to play on childhood mortality and improving childhood mortality is a national priority. The present study was planned to 1) determine the mortality rate among neonates and infants. 2) identification of pattern of various factors in relation to infant mortality and 3) to identify the causes of death in this age group. METHOD All the deaths in children under 12 months during July 2005 to June 2006 in Jawan block of district Aligarh, India were recorded. The cause of death was ascertained using the standard verbal autopsy procedure. RESULTS In the study period, 446 live births and 37 deaths in children under one year of age were reported. The neonatal and infant mortality rates were 49.4 and 83.0 per thousand live births respectively. The main causes of infant deaths were birth asphyxia, diarrhoea, pneumonia, prematurity (including Low birth weight and malnutrition). CONCLUSION Most of the death among infants are preventable, though promotion of institutional deliveries, strengthening of referral system, early recognition of danger signs and periodic retraining of health workers.

Abstract
Frequency-modulation atomic force microscopy (FM-AFM) relies on an accurate tracking of the resonance frequency of a scanning probe. It is now used in environments ranging from ultrahigh vacuum to aqueous solutions, for slow and for fast imaging, with probes resonating from a few kilohertz up to several megahertz. Here we present a versatile experimental setup that detects amplitude, phase, and frequency of AFM probes for resonance frequencies up to 15 MHz and with >70 kHz maximum bandwidth for amplitude/phase detection. We provide generic parameter settings for variable-bandwidth frequency detection and test these using our setup. The signal-to-noise ratio of the frequency detector is sufficiently high to record atomic-resolution images of mica by FM-AFM in aqueous solution.

Abstract
Synovial osteochondromatosis is a rare condition, found mainly in larger joints, where as it is particularly rarer in small joints especially the metatarsophalangeal joint. We report the case of a 45-year-old man with primary synovial osteochondromatosis in the first metatarsophalangeal joint. Following surgical intervention, the diagnosis was confirmed with histological examination. The patient had successful management and is completely symptom free on 12-month review. A summary of the case and review of the current literature with the incidence of this condition and risks involved are discussed.

Abstract
Aspiration of foreign bodies into the tracheobronchial tree is a common presentation in children, but less so in adults. Successful extraction depends on the type of foreign body aspirated, location of the foreign body in the tracheobronchial tree, the experience of the operator and the instrumentation available. We report on our management of a patient who presented with an aspirated foreign body.

Abstract
The clinical picture in severe cases of pandemic (H1N1) 2009 influenza is markedly different from the disease pattern seen during epidemics of seasonal influenza, in that many of those affected were previously healthy young people. Current predictions estimate that, during a pandemic wave, 12-30% of the population will develop clinical influenza (compared with 5-15% for seasonal influenza) with 4% of those patients requiring hospital admissions and one in five requiring critical care. This review covers the background, clinical presentation, diagnosis, and treatment. The role of immunization and antiviral drugs is discussed. Experience from the first wave of pandemic (H1N1) 2009 influenza suggests that a number of infected patients become critically ill and require intensive care admission. These patients rapidly develop severe progressive respiratory failure which is often associated with failure of other organs, or marked worsening of underlying airways disease. The critical care management of these patients and the implications for resources is reviewed. Guidance from a range of bodies has been produced in a relatively short period of time in response to pandemic (H1N1) 2009 influenza. Disease severity has the potential to change, especially if there is virus mutation. Clinicians must be prepared for the unexpected and continue to share their experiences to maximize patient outcomes.

Abstract
Pakistan faces a human resources for health (HRH) crisis. A cross-sectional survey was conducted to overview frontline health workers. A total of 750 health facilities were surveyed across Pakistan. The median estimate of public sector health care workers in the district health system in Pakistan is 417 288, including 46 153 estimate of public sector health care workers in the district health system in Pakistan is 417 288, including 46 153 doctors and 41 032 nurses. Another estimated 20 000 doctors work in public sector tertiary care hospitals across the country. A total of 3549 health care workers were interviewed regarding job satisfaction and work environment. The private sector had better work environment scores compared with the public sector. Policy dimensions showed an absence of robust policies in practice. The public sector is inadequately staffed and job satisfaction and work environment need improvement. HRH crisis countries should share experiences, and developmental partners should support them in overcoming the HRH crisis.

Abstract
Sequential Organ Failure Assessment (SOFA) score based triage of influenza A H1N1 critically ill patients has been proposed for surge capacity management as a guide for clinical decision making. We conducted a retrospective records review and SOFA scoring of critically ill patients with influenza A H1N1 in a mixed medical-surgical intensive care unit in an urban hospital. Eight critically ill patients with influenza A H1N1 were admitted to the intensive care unit. Their mean (range) age was 39 (26-52) years with a length of stay of 11 (3-17) days. All patients met SOFA score based triage admission criteria with a modal SOFA score of five. Five patients required invasive ventilation for a mean (range) of 5 (4-11) days. Five patients would have been considered for withdrawal of treatment using SOFA scoring guidelines at 48 h. All patients survived. We conclude that SOFA score based triage could lead to withdrawal of life support in critically ill patients who could survive with an acceptably low length of stay in the intensive care unit.
