Observed anomalous upwelling in the Lakshadweep Sea during the summer monsoon season of 2005

Repeat near-fortnightly expendable bathythermograph (XBT) transects made along Kochi-Kavaratti (KK) shipping lane in the Lakshadweep Sea (LS) during 2002–2006 are examined to describe the observed year-to-year variability of upwelling during summer monsoon season (SMS). Among all the years, the upwelling characterized by up-sloping of 25°C isotherm is relatively weaker and persisted until November during SMS of 2005 and is stronger during the SMS of 2002. As a result of prolonged upwelling, the sea surface temperature has shown cooling extending into the postmonsoon season. The estimated marine pelagic fish landings along the southwest coast of India (SWCI) have also shown increase until December. The governing mechanisms both in terms of local and remote forcings are examined to explain the observed anomalous upwelling during SMS of 2005. The equatorward alongshore wind stress (WS) along the KK XBT transect persisted in a transient manner beyond September only during SMS of 2005. The westerly wind bursts over the equator during the winter of 2004–2005 are both short-lived and relatively weaker triggering weaker upwelling Kelvin waves that propagated into LS in the following SMS of 2005. The observed distribution of negative sea surface height anomaly in the LS is relatively weaker during the SMS of 2005 and lasted longer. The correlation analysis suggests that the local alongshore WS off the SWCI and the remote forcing from the southern coast of Sri Lanka has greater influence on the observed interannual variability of upwelling in the LS when compared to the remote forcing from the equator

Isolated cleft of the ala nasi: A report of seven cases

Craniofacial clefts other than cleft lip & palate are reported to be 1.4 to 4.9 per 100,000 live births. Of these, clefts of nose are usually associated with other clefts. Isolated cleft of Ala is rare, 0.7% of all clefts reported by Monasterio. In an analysis of photographic records of 3,500 consecutive patients with craniofacial clefts including cleft lip & palate registered with us between 1985- 2012 which were accessed through our data base, 13 patients with nasal clefts were identified, seven out of which had Isolated cleft of the Ala. All were treated by a rotation flap of the Ala with good results with the longest follow up of 14Yrs. The authors have emphasised the rarity of the condition and presented a simple surgical procedure for correction. In the opinion of the authors this very simple procedure which can be performed by the junior surgeon gives a good long term result in the management of cleft Ala

Alterations in Plasma Amino Acid Levels in Chronic Pancreatitis

Context Dietary proteins and amino acids can modulate pancreatic function. Objective Our aim was to estimate the levels of plasma amino acids in chronic pancreatitis patients and study their relationship with disease characteristics as well as exocrine and endocrine insufficiency. Patients One hundred and seventy-five consecutive adult patients with chronic pancreatitis: 84 patients with alcoholic chronic pancreatitis and 91 patients with tropical chronic pancreatitis. One hundred and thirteen healthy controls were also studied. Design Prospective study. Main output measures Disease characteristics and imaging features were recorded. Plasma-free amino acid levels were estimated using reverse-phase high-performance liquid chromatography. Polyclonal antibody ELISA was used to assess pancreatic fecal elastase-1. Results The majority of the plasma free amino acid levels decreased in chronic pancreatitis patients whereas glutamate, glycine, proline and lysine were elevated as compared to the controls. Multivariate logistic regression analysis revealed that the decrease in branched chain amino acid concentration was significantly associated with the presence of diabetes and low fecal elastase-1. In addition, a significant positive correlation was observed between branched chain amino acids and pancreatic elastase-1 (rs=0.724, P<0.001). Conclusion Reductions of plasma amino acid levels are seen in chronic pancreatitis, particularly sulphur containing amino acids and branched chain amino acids. Selective amino acid deficiencies seem to correlate with exocrine and endocrine insufficiency.Image: Amrita Institute of Medical Sciences. Cochin, Kerala, India
