Changing profile of banking

The recent data on deposits and credit of scheduled commercial banks published by the Reserve Bank of India provide valuable insights into the distribution of banking business across the country. As on March 31, 2009, the number of banked centres served by scheduled commercial banks stood at 34,636. A very large number of them – over 28, 000-were single office centres, mostly in rural and semi-urban areas. At the other extreme, there were 61 centres having 100 or more bank branches. The concentration of bank branches in a few urban and metro centres is by no means a new development. But for the unprecedented branch network expansion that followed the nationalization of large banks in 1969, the concentration would have been even more pronounced. In the reform era beginning the early 1990s, the emphasis shifted in favour of consolidation. With considerations of profitability dictating the strategic plans, branch expansion, especially to rural areas, was no longer a priority. Instead, banks tended to converge on centres that had business potential. According to the RBI, the top hundred centres, arranged according to the size of deposits, accounted for 69.2 per cent of the total deposits, while the top hundred ranked according to the size of credit accounted for 78.5 per cent of total bank credit as on March 31 this year.

The skewed pattern of distribution obviously meant heightened competition in certain centres while in a much larger number of places, including those with no banks at all, the urgent task has been to extend the range of financial services. Among the banks, non-price competition has become the norm. Technology has been harnessed in a variety of ways to take on competition and, more importantly, to reduce transaction costs. It has enabled the opening of new delivery channels such as internet banking and mobile banking. But its role in extending financial services across the country has not been fully appreciated. Quite obviously the goal of inclusive banking has to be achieved in a context where the traditional model of branch banking cannot be entirely relied upon. Technological applications are already enabling business correspondents and others to deliver many types of services now offered by a bank. However, over the medium-term it is highly unlikely that the traditional bank model will lose its relevance even in rural areas. In fact, these bank branches might be called upon to undertake newer services, including those having a development dimension such as delivery of subsidies and conditional cash transfers.

Global interest in strategy: Colombo

Several countries, including Pakistan, have expressed the desire to learn from Sri Lanka’s experience in successfully fighting terrorism, according to Sri Lankan Army chief Jagath Jayasuriya. Speaking at his Regimental Headquarters here on Thursday, Lieutenant-General Jayasuriya said the Army had no hesitation in sharing the knowledge with the armies of other countries. The Army chief said, in his assessment, Sri Lanka’s military strength needed to be enhanced from the present 2, 00,000 to 2, 25,000. “The actual new recruits could be around 50,000as for the last two-and-half years those eligible to retire were not permitted due to war.” Lieutenant-General Jayasuriya said his endeavour would be to transform the Army to cope with post-conflict challenges.

He said the Army would soon send more of its engineers for additional demining work. “I have already sent 400 engineering troops for de-mining and I am sending more battalions to be trained in ‘humanitarian demining,” he said and added that the military did not have a precise estimate of land mines planted by the LTTE. “An area about 3,100 square miles [8,000 sq.km.], including Mannar, Kilinochchi, Mullaithivu and parts of Jaffna districts, must be demined before it will be safe enough for the Tamils to return. Without de-mining, I don’t think we can take a chance,” said the General.

“We have four international non-governmental organizations helping us now and I want to use mechanized mine clearing to speed up the process,” he added. Nearly 2.6 lakh war-displaced persons are sheltered in temporary government transition camps and pressure is growing on the government to let them return to their original homes.

The government is committed to a 180-day programme for rehabilitation but holds that there is no way the war-displaced can return immediately as the areas, which were earlier under the control of the LTTE, are heavily mined and basic infrastructure is in rubble.

Habitat and food mark out tigers in Sunderbans

Living in the intertidal habitat among marshy thickets, having become accustomed to the saline water, and but often without the trademark element of surprise, the Royal Bengal Tiger of the Sunderbans may have evolved differently from its brethren in peninsular India, according to experts here.

Forest Department Officials are constantly discovering aberrant behaviour patterns. The July 17 finding of poisonous snake in a tiger’s stomach is one such example. “While tigers are known to eat snakes, this is perhaps the first record of a tiger eating poisonous ones,” said Richa Dwivedi, deputy field director of the Sunderbans Biosphere Reserve.

“Although it is yet to be confirmed scientifically that the tiger is genetically different from terrestrial tigers as the DNA analysis has not been done, there are certainly many physiological adaptations,” said Pradeep Vyas, the State Forest Department’s chief conservator of forests (Central).

There is strong evidence of the fact that tigers in the Sunderbans drink saline water, says N.C. Bahuguna, director, Sunderbans Biosphere Reserve.

“There are nearly 270 tigers in the Sunderbans, but the few fresh water ponds that were ponds that were created are not sufficient to support this large a population,” said Pranabesh Sanyal, former director. “In any case, there were no fresh water ponds before 1977, so what else could the tigers drink then?

These tigers have to negotiate harsh habitat conditions, apart from non-availability of fresh water. The muddy and marshy areas, dotted with pneumatophores (spiked roots of mangroves which abound in these forests), have forced them to hunt differently, says Mr. Vyas. “When they walk on the wet soil, it is often noisy and they can’t stealthily approach their prey, like tigers normally do.”

Aquatic diet:

Difficulties faced in hunting may be the cause of their alternative food habits, although experts differ on the reasons.

“Studies have shown that nearly 20 per cent of the diet of tigers in these parts is aquatic including fish, crabs and turtles,” said Mr. Sanyal, who suggested that easy availability of these substitutes might cause them to eat this food. At times, even grasshoppers have been found in the stomach contents of these tigers, according to Mr. Bahuguna.

Link between rice intake and diabetes found

Rice is a major source of dietary carbohydrates. But the link between diet, rice in particular, and diabetes has not been studied in great detail till now.

A paper published recently in the British Journal of Nutrition shows a clear link between the consumption of white, polished (refined) rice and the prevalence of diabetes.

Every tenth participant of the 2001-02 phase I CURES (Chennai Urban Rural Epidemiology Study) conducted by Dr.V.Mohan of the Dr.Mohan’s diabetes specialities center in Chennai was chosen for the current study to see for a link between dietary carbohydrate and diabetes. 1,843 people who did not know their diabetes status were selected for the study.

The participants: the chosen participants were then tested for diabetes and their food habits were recorded. The risk factor for diabetes such as sedentary lifestyle, age, BMI (body mass index), etc., were adjusted between the kind/ quantity of food consumed and diabetes.

When the food habits of the chosen participants were studied, it became clear that those who consumed more rice (Polished and refined) were more likely to have diabetes. For instance, the study participants were spilt into four quartiles based on the amount of various food consumed. It was found that people in the lowest quartile consumed about 320 grams per day of rice compared with 516 grams per day by those in the highest quartile.

“What we found was, as the amount of rice consumption increased, the consumption of other food items, like fruits and vegetables, legumes and diary products became less,” said Dr. Mohan. “We found a link not just between carbohydrate consumption and diabetes but the kind of carbohydrate consumed and its effect”, said Dr. Mohan.

Carbohydrate rich:

The carbohydrate derived from polished white rice is 66 per cent of the total carbo hydrate in take.

“Another interesting finding was that as the increased intake of rice was at the cost of other food items,” he said. For instance, in the lowest quartile that consumed less rice, the intake of fruits was about 300 grams per day, while fruit consumption in the highest quartile was 233 grams per day. The same trend was observed in the case of other food items.

But the biggest positive link was found in the case of dairy products. Those having the least quantity of dairy products were more likely to have diabetes; those who consumed the most had less chances of having diabetes.

Polished rice:

“It is not that our eating habits have changed in the recent past. Our fathers and grandfathers had also consumed rice. But the kind of rice they consumed and what we consume today are totally different,” he said.

The rice that we get today is the highly refined and polished variety. “The more polished the rice, the more glycaemic index (GI) it would have,” he said. The GI indicates the glucose-raising effect of a food.

Polishing removes the bran and the germ. While the bran contains fibre, protein and vitamin B-complex; polished rice has only starch, which is nothing but carbohydrate.

According to Dr. Mohan, rice used to be 2 per cent polished earlier; now it is polished to 8 per cent -10 per cent.

The only good news is that increased of the ill-effects of various food items has made many companies produce healthier food products.

Healthy food:

Rice that is relatively less polished is now available in the market. Similarly, many products made from whole wheat are available.

Chronic paronychia

Chronic paronychia is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens which has been present for at least 6 weeks at the time of diagnosis.

What are the symptoms?

• One or several fingernails are usually affected,
• Sudden pain, redness like acute paronychia
• Pus discharge
• Retraction of the proximal nail fold and absence of the adjacent cuticle.
• The nail plate becomes thickened and discolored, with transverse ridges.
• Nail loss.

What is the cause for this infection?

The cuticle separates from the nail plate, leaving the region between the proximal nail fold and the nail plate vulnerable to infection.

Who are all prone to get this problem?

• Laundry workers,
• House and office cleaners,
• Food handlers, cooks, dishwashers, bartenders,
• Chefs,
• Fishmongers, confectioners,
• Nurses,
• Swimmers.

What is the common organism thought to cause this infection?

• Candida albicans (controversial)

How to prevent?

• Apply moisturizing lotion after hand washing.
• Avoid chronic prolonged exposure to contact irritants and moisture (including detergent and soap)
• Avoid finger sucking.
• Keep nails short.
• Use rubber gloves, preferably with inner cotton glove or cotton liners.

What is the treatment?

• Steroids and Antifungal agent (ointment) used to treat and prevent recurrence.
• In severe cases- Oral antifungal and/or Steroids.

What are the options for non responders?

• Simultaneous total or partial avulsion of the nail plate.
• En bloc excision of the proximal nail fold is effective.
• Eponychial marsupialization, with or without nail removal.
