Abstract
Cytotoxic antiproliferative chemotherapeutic agents are the mainstay of treatment in cancers. Chemotherapy is usually administered every 2-3 weeks. Along with acute toxicity and long-term effects of cumulative doses, this strategy potentially allows regrowth of the tumor in the interval period and leads to the emergence of resistant populations of tumor cells. Moreover, even with intense chemotherapy, the outcome is stagnating for most of the tumors. There has been recent interest in the use of chemotherapy in fractionated doses which is far below the maximum tolerated dose. This is called metronomic scheduling of chemotherapy. Here, we review the biology and evidence for metronomic chemotherapy.

Abstract
BACKGROUND Cluster analyses have enhanced understanding of the heterogeneity of both paediatric and adult wheezing. However, while adolescence represents an important transitional phase, the nature of young adult wheeze has yet to be clearly characterised. OBJECTIVES To use cluster analysis to define, for the first time, clinically relevant young adult wheeze clusters in a longitudinal birth cohort. METHODS K-means cluster analysis was undertaken among 309 currently wheezing subjects at 18 years in the Isle of Wight birth cohort (N = 1456). Thirteen disease-characterising clustering variables at 18 years were used. Resulting clusters were then further characterised by severity indices plus potential risk factors for wheeze development throughout the 1st 18 years of life. RESULTS Six wheeze clusters were identified. Cluster 1 (12.3%) male-early-childhood-onset-atopic-wheeze-with-normal-lung-function had male predominance, normal spirometry, low bronchodilator reversibility (BDR), intermediate bronchial hyper-responsiveness (BHR), high atopy prevalence and more admissions. Cluster 2 (24.2%) early-childhood-onset-wheeze-with-intermediate-lung-function had no specific sex association, intermediate spirometry, BDR, BHR, more significant BTS step therapy and admissions. Cluster 3 (9.7%) female-early-childhood-onset-atopic-wheeze-with-impaired-lung-function showed female predominance, high allergic disease comorbidity, more severe BDR and BHR, greatest airflow obstruction, high smoking prevalence, higher symptom severity and admissions. Cluster 4 (19.4%) female-undiagnosed-wheezers had adolescent-onset non-atopic wheeze, low BDR and BHR, impaired but non-obstructed spirometry, high symptom frequency and highest smoking prevalence. Cluster 5 (24.6%) female-late-childhood-onset-wheeze-with-normal-lung-function showed no specific atopy association, normal spirometry, low BDR, BHR and symptom severity. Cluster 6 (9.7%) male-late-childhood-onset-atopic-wheeze-with-impaired-lung-function had high atopy and rhinitis prevalence, increased BDR and BHR, moderately impaired spirometry, high symptom severity and higher BTS step therapy. CONCLUSIONS AND CLINICAL RELEVANCE Young adult wheeze is diverse and can be classified into distinct clusters. More severe clusters merit attention and are associated with childhood onset, atopy, impaired lung function and in some, smoking. Smoking-associated undiagnosed wheezers also merit recognition. Better understanding of young adult wheeze could facilitate better later adult respiratory health.

Abstract
Parapharyngeal tumors are less common in clinical practice and are often difficult to diagnose upon clinical examination due to the anatomic complexity of the region. We report a rare case of extracranial parapharyngeal space meningioma presenting as a cervical mass with encasement of cranial nerves giving tram track appearance and features on various imaging modalities [Radiographs, Ultrasound, Computed tomography (CT) scan and Magnetic resonance imaging (MRI)].

Abstract
Low portal vein flows in liver transplant have been associated with poor allograft survival. Identifying and ameliorating causes of inadequate portal flow is paramount. We describe successful reversal of significant splenic vein siphon from a spontaneous splenorenal shunt during liver transplant. The patient is a 43-year-old male with cirrhosis from hepatitis C and Budd-Chiari syndrome, who had a variceal hemorrhage necessitating an emergent splenorenal shunt with 8 mm PTFE graft. Imaging in 2006 revealed thrombosis of the splenorenal shunt and evidence of a new spontaneous splenorenal shunt. The patient developed hepatocellular carcinoma and underwent transplant in 2009. After reperfusion, portal flows were low (150-200 mL/min). A mesenteric varix was ligated without improvement. Due to adhesions, direct collateral ligation was not attempted. In order to redirect the splenic siphon, the left renal vein was stapled at its confluence with the inferior vena cava. Portal flows subsequently increased to 1.28 L/min. Postoperatively, the patient had stable renal and liver function. We conclude that spontaneous splenorenal shunts can cause low portal flows. A diligent search for shunts with understanding of flow patterns is critical; ligation or rerouting of splanchnic flow may be necessary to improve portal flows and allograft outcomes.

Abstract
BACKGROUND The laryngoscope has been identified as a potential source of cross-infection, because of blood and bacterial contamination. In India, there are no guidelines for cleaning and disinfection of anesthesia-related equipment. Practices for decontamination of laryngoscopes vary widely and in most healthcare institutes, laryngoscope blades are re-used after cleaning with tap-water. MATERIALS AND METHODS We prospectively compared two techniques for decontamination of laryngoscope blades - a) washing with tap-water and b) washing with tap-water followed by disinfection by immersing in 5% v/v (volume/volume, 1:20 dilution) aldehyde-free biguanide agent for 10 min. We calculated the cost-effectiveness of using 5% v/v aldehyde-free biguanide agent for disinfection of laryngoscopes. We also conducted a survey to assess the decontamination practices in other Indian hospitals. RESULTS Overall bacterial growth was 58% (29 out of 50 blades) after tap-water cleaning (of which 60% were pathogenic organisms) versus 3.4% (one out of 29 blades) after tap-water cleaning followed by immersion in disinfectant (all of which were commensals). The cost of disinfection with biguanide was Indian Rupees 1.13 (20 US cents) per laryngoscope. Most hospitals in India do not have guidelines regarding laryngoscope decontamination between uses, and cleaning with tap water is a commonly used method. CONCLUSION Cleaning of laryngoscope blades with tap-water is a commonly used but inadequate method for decontamination. Washing with tap-water followed by disinfection with 5% v/v aldehyde-free biguanide for at least 10 min is an effective and inexpensive alternative. National guidelines for the decontamination of anesthesia equipment are necessary.

Abstract
We report a case of persistent urogenital sinus with hydrocolpos and associated renal anomalies diagnosed prenatally at 30 weeks' gestation. The prenatal findings were confirmed on postnatal ultrasonography and genitogram with voiding urethrogram. The imaging features and a review of the literature are discussed. The possibility of hydrometrocolpos secondary to urogenital sinus should be considered on prenatal sonography in the presence of a presacral cystic mass with clear urine or turbid contents and a fluid-debris level (cervical or vaginal secretions). Because the prognosis and neonatal management of isolated hydrocolpos (which usually resolves spontaneously) differ greatly from those of hydrocolpos associated with a cloacal malformation, it is important to diagnose prenatally any associated anomalies in order to allow optimal postnatal management.

Abstract
OBJECTIVE To test the hypothesis that diffuse abnormalities precede axonal damage and atrophy in the MRI normal-appearing tissue of relapsing-remitting (RR) multiple sclerosis (MS) patients, and that these processes continue during clinical remission. METHODS Twenty-one recently diagnosed mildly disabled (mean disease duration 2.3 years, mean Expanded Disability Status Scale score of 1.4) RR MS patients and 15 healthy matched controls were scanned with MRI and proton MR spectroscopic imaging ((1)H-MRSI) at 3 T. Metabolite concentrations: N-acetylaspartate (NAA) for neuronal integrity; choline (Cho) for membrane turnover rate; creatine (Cr) and myo-inositol (mI) for glial status were obtained in a 360 cm(3) volume of interest (VOI) with 3D multivoxel (1)H-MRSI. They were converted into absolute amounts using phantom replacement and normalised into absolute concentrations by dividing by the VOI tissue volume fraction obtained from MRI segmentation. RESULTS The patients' mean VOI tissue volume fraction, 0.92 and NAA concentration, 9.6 mM, were not different from controls' 0.94 and 9.6 mM. In contrast, the patients' mean Cr, Cho and mI levels 7.7, 1.9 and 4.1 mM were 9%, 14% and 20%, higher than the controls' 7.1, 1.6 and 3.4 mM (p = 0.0097, 0.003 and 0.0023). CONCLUSIONS The absence of early tissue atrophy and apparent axonal dysfunction (NAA loss) in these RR MS patients suggests that both are preceded by diffuse glial proliferation (astrogliosis), as well as possible inflammation, demyelination and remyelination reflected by elevated mI, Cho and Cr, even during clinical remission and despite immunomodulatory treatment.

Abstract
BACKGROUND/OBJECTIVE Reproductive tract infections (RTI) present major health, social, and economic problems in developing countries. Our objective was to describe the prevalence and risk factors of RTIs in a population based sample of women aged 18-45 years. METHOD 2494 women of 3000 randomly selected from the population defined by a primary health centre catchment area consented to participate. Participants were interviewed regarding complaints and risk factors. Laboratory specimens were collected for the diagnosis of RTIs. Analyses of risk factors were carried out separately for the outcomes of sexually transmitted infections: chlamydia, gonorrhoea, trichomoniasis; and endogenous infections: bacterial vaginosis (BV) and candida. RESULTS Endogenous infections were relatively common (BV 17.8%; candida 8.5%), and sexually transmitted infections (STI) were infrequent (4.2%). Factors indicative of poverty and marginalisation were associated with STIs and BV. Gender disadvantage, particularly spousal violence, was associated with BV, while concern about a husband's extramarital relationships, an indicator of sexual risk, was associated with STI. Husband's discharge was strongly associated with STI, and a non-white vaginal discharge was associated with both STI and BV. Condom use and oral contraceptive use were associated with a reduced risk of BV. CONCLUSIONS Most of the population burden of RTIs is attributed to endogenous infections. Socioeconomic deprivation and gender disadvantage are associated with raised risk for BV, while the risk factors for STIs indicated that disadvantaged women were likely to be infected by their husbands.
