Upper respiratory tract infection (URTI) or commonly known as “common cold” occurs frequently in young children and is characterized by a complex set of symptoms. The URTIs are caused by numerous types of viruses, which include the rhinovirus, coronavirus, parainfluenza, respiratory syncytial virus (RSV), adenovirus, human metapneumovirus, and influenza. The recently discovered bocavirus has also been found to be associated with URTI. The specific manifestations of URTIs include rhinitis, sinusitis, nasopharyngitis, epiglottitis, laryngitis, laryngotracheitis, and tracheitis. Being most accountable for absence from school and unnecessary medical care, URTIs are regarded as trivial among the medical fraternity. However, URTIs are the foremost causes of mild morbidity in children. A majority of URTIs spread through person-to-person contact of the infected secretions. Viruses may directly invade the mucosal lining of the upper airway. Bacterial infection may also occur in a similar manner but superinfection of a viral infection may occur. The infection may begin when secretions get passed on from a contaminated hand to the nose or mouth. Droplet infection results from direct inhalation of respiratory droplets released when infected person coughs or sneezes. As viruses and bacteria enter the body, they come across various barriers such as physical, mechanical, humoral, and cellular immune defenses. Hair lining the walls of the nasal cavity, mucus coating the upper respiratory tract, and ciliated cells in the lower respiratory tract act as physical barriers in trapping the pathogens and transferring them up to the pharynx from where they are ingested into the stomach. The adenoids and tonsils with their immune cells play a role in defense mechanism. Humoral and cellular immunity help reduce infections throughout the respiratory tract. Apart from these, the normal nasopharyngeal flora defends against the pathogenic bacteria. Therefore, children with a deficient humoral and phagocytic immune function are at a greater risk for a difficult and extended course of disease. Incubation periods before the manifestation of EDITORIAL Dear reader, Acute respiratory tract infections (RTI) are the most common illnesses experienced in childhood, primarily due to developing/immature immune defense system. It is approximated that children usually will suffer at least 3 to 8 respiratory illnesses caused by virus every year. Peak incidence of viral and bacterial pharyngitis is seen in children between 4 and 7 years. The “Cover Page” article features a review on the pathophysiology, incidence, and natural history of RTIs in children. The “Clinical Studies” section of this issue features the beneficial effects of Septilin drops, a phytopharmaceutical formulation of The Himalaya Drug Company effective in the management of chronic and recurrent RTIs. The section also features other articles that discuss about the clinical efficacy and safety of Koflet-H lozenge, a newly introduced product, in the management of pharyngitis; Renalka syrup in urinary tract infection, and Hairzone in the management of diffuse hair loss. In addition to these, the issue also discusses the health benefits of Saraca indica and Cissus quadrangularis in “Health from Herbs” section. “In Focus” section features a meta-analysis that discusses the efficacy and safety of Liv.52 in preventing hepatotoxicity in patients receiving antitubercular drugs.

The incubation time for rhinoviruses and group A streptococci is 1 to 5 days, influenza and parainfluenza viruses incubate for 1 to 4 days and RSV for a week. Narrowing of the airway at the level of epiglottis and larynx due to inflammation may cause compromized airflow which is critical in children. A thorough understanding of the natural history of the disease, warning signs, and sequelae is indispensable for the management of childhood URTIs. Incidence The incidence of URTI differs by age. The rates of nasopharyngitis are highest in children below 5 years and it is approximated that children usually will suffer at least 3 to 8 respiratory illnesses caused by virus every year.

Epiglottitis generally occurs in children between 2 and 7 years and is peak at the age of 3 years. Laryngitis and laryngotracheitis occurs in children between 6 months and 6 years and peak incidence is in second year of life. Natural History of URTI The natural history of URTI in children has been better documented with the advent of sensitive and specific reverse transcriptase polymerase chain reaction techniques. The first community-based natural history study was conducted in the Virginia, USA in which 81 children between 5 and 10 years of age were enrolled and data was collected beginning from the onset of symptoms to the 10th day. Results showed that rhinovirus was isolated in almost 37 cases which accounts to 50% of cases. The commonest signs were coughing and sneezing and the most common symptoms were nasal congestion and a runny nose. All these signs and symptoms continued for the first week. The main inference from the natural history data is that coughing is very common in children and can persist till the ninth day whereas fever is uncommon beyond the first day and its persistence suggests other causes such as influenza or a bacterial complication (otitis media or sinusitis). Lower Respiratory Disease Linked to Rhinovirus In two recent studies conducted on hospitalized children, it has been documented that a significant number of lower respiratory diseases are caused by the rhinovirus. In a US study, the rhinovirus was isolated in about 26% of the children below 5 years of age, hospitalized for acute respiratory disease. The rhinovirus was identified more frequently than the RSV which was previously associated with most of the lower airway morbidities and a history of asthma. Apnea was common in infants below 6 months of age. In a study conducted in Spain, children below 2 years of age were enrolled and the rhinovirus was associated in 25% of the hospitalized children. Multiple viruses were detected in almost 40% of children signifying a role of coinfection in the pathogenesis of respiratory disease. –– Excerpted from: Cotton MF, et al. SA Fam Pract. 2008;50(2):6-12. Recurrent infections are more common in children due to immature and imbalanced immune defense system. In children with allergy, unresolved inflammatory response adds to the burden on the immature immune system. The key to managing these infections lies in immunomodulation (boosting immune responses that protect the host and reducing immune responses that affect the host). Septilin drops, from The Himalaya Drug Company, potentiates immune defenses by increasing immunoglobulin levels, improving chemotaxis, and stimulating phagocytosis by activating macrophages and increasing levels of polymorphonuclear cells; and reduces inflammation and allergy by decreasing pro-inflammatory cytokines, eosinophils, and IgE levels. Septilin drops is indicated as a co-prescription with anti-infective therapy, and for recurrent respiratory and ENT infections, skin and soft tissue infections, and resistance to antibiotic therapy. www.himalayahealthcare.com Health from Herbs Terminalia arjuna Terminalia arjuna is native to the Indian subcontinent. It is an evergreen tree with yellow flowers and conical leaves and grows up to 100 feet (30 meters). In Ayurvedic medicine, Arjuna is the most frequently prescribed herb for cardiovascular health. The bark of T arjuna contains calcium salts, magnesium salts, tannins, and glucosides. It acts as a stimulant, tonic, and astringent. In addition, it has been found to possess antibacterial and antimutagenic properties. It is used to treat hemorrhage, diarrhea, dysentery, edema, skin problems, and fractures. Studies have shown that T arjuna possesses cardioprotective effect. The results of an experimental study suggested that T arjuna English name Arjuna Sanskrit/Indian name Arjuna bark extract has a significant prophylactic and therapeutic beneficial effect on protection of heart against isoproterenol-induced chronic heart failure possibly through maintaining endogenous antioxidant enzyme activities, inhibiting lipid peroxidation and cytokine levels.1 Experimental studies have also revealed that T arjuna bark exerts significant inotropic and hypotensive effect, increases coronary artery flow and protects myocardium against ischemic damage. It has also been detected to have mild diuretic, antithrombotic, prostaglandin E(2) enhancing and hypolipidemic activity. There is ample clinical evidence of its beneficial effect in coronary artery disease alone and along with statin.2 Allium sativum Allium sativum is a scapigerous perennial herb with underground compound bulb and a smooth round stem, which is enclosed with tubular leaf sheath. A sativum is found throughout India and grows well in mild climate. Some of the key chemical constituents of A sativum are S-allyl-L-cysteine sulfoxide (alliin), gamma-glutamyl-S-allyl-Lcysteine, and diallyl trisulfide. In Western Europe and the US, A sativum is one of the most popular herbs being used to reduce risks associated with heart disease. It has shown to prevent hardening of arteries, reduce elevated blood cholesterol levels, improve blood flow, and manage hypertension. Recently, a study was conducted to identify the role of garlic oil in diabetes-induced cardiomyopathy. Streptozotocin-induced diabetic rats were administered with garlic oil (0, 10, 50, or 100 mg per kg of body References weight) every two days for 16 days. The researchers noted garlic oil to ameliorate cardiac contractile dysfunction and apoptosis in a dose-dependent manner, and concluded that it has a significant potential in offering protection against diabetes-induced cardiomyopathy.3 Another recent research has reported that A sativum homogenate in combination with hydrochlorothiazide (HCTZ) showed synergistic antihypertensive and cardioprotective properties in rats with hypertension and myocardial damage.4 English name Sanskrit/Indian name Garlic Lasuna A sativum is also reported to have antifungal, anti-platelet, diuretic, anti-cancer, antihelminthic, aphrodisiac, and antibacterial properties. The herb is found to be useful in numerous medical conditions including bronchitis, whooping cough, constipation, asthma, fever, diabetes, dyspepsia, duodenal ulcers, tuberculosis, hemorrhoids, sciatica, leucoderma, and dental caries.5 1.

This study included 50 patients in the age group of 18 to 60 years suffering from mild-to-moderate pharyngitis. A complete head and neck examination was performed to exclude other diseases and all the patients were instructed to take Koflet-H lozenges 3 times a day for 6 days. No other medications or antiinflammatory drugs were taken during the study period. All the patients were evaluated for their presenting symptoms at baseline, day 3, and day 6. Statistically significant improvements were observed in the signs and symptoms of pharyngitis on the third and sixth day when compared with their baseline values (Table 1). Also, there was a major improvement in the hematological parameters as compared to baseline values. None of the patients experienced any significant adverse reactions during the entire study period and Koflet-H lozenges relieved signs and symptoms of pharyngitis such as throat congestion, cough, hoarseness of voice, pain, and inflammation. The overall patient compliance and acceptance was excellent. Therefore, it can be concluded that Koflet-H lozenges are effective as well as safe in patients suffering from mild-tomoderate pharyngitis. Table 1.

The study included a total of 20 children with URTI in the age group of 1 to 3 years. After physical examination including a detailed examination of ear, nose, throat and chest, and recording of vital signs, Septilin drops was given for a period of 2 weeks, at a dose of 3.5 ml twice daily for children between 1 and 2 years and 4 ml twice daily for children between 2 and 3 years. All the children were followed up at the end of 4th day, 1 week, and 2 weeks, and the safety and efficacy evaluation of the product was done during each visit. Results of the clinical trial showed that Septilin drops significantly reduces symptoms of URTI such as common cold, chronic cough, pharyngitis, tonsillitis, and adenoiditis (Table 2). No adverse reactions or withdrawal from trial were reported or observed throughout the study period and the overall compliance to the treatment was excellent. Therefore, it can be concluded that Septilin drops is effective and safe in the treatment of URTI in children. Table 2.

The study comprised 40 patients between the ages of 51 and 60 years. There were 2 major groups of patients with symptoms of UTI; one with indwelling catheters comprising 21 cases and the other without indwelling catheters, 19 cases. Renalka syrup was given to all the patients at a dosage of 2 teaspoonfuls thrice daily before meals for 4 weeks. The patients were followed up on a weekly basis and assessed for their clinical signs and symptoms. Comparative study showed that efficacy of Renalka syrup remained unaltered in both catheterized and noncatheterized groups of patients (Table 3). Hematological examination including the total leucocyte count (TLC), differential leucocyte count (DLC), estimation of Hb%, blood urea, and serum creatinine were done before, during, and after the therapy. Results obtained showed that there are no significant changes in the TLC, DLC, Hb%, blood urea, and serum creatinine after therapy using Renalka syrup. Therefore, it can be concluded that Renalka does not have adverse effects on renal function and can be safely used to control symptoms of UTI. A clinical study was planned and conducted to evaluate the safety and efficacy of Hairzone solution in diffuse hair loss. A total of 28 patients with diffuse hair loss were included in the study. All of them were advised to gently massage the whole area of the scalp with Hairzone solution, leave it overnight and rinse off in the morning. After 6 weeks, efficacy of the therapy was evaluated using parameters such as moisturizing effect, reduction in hair fall, and other symptoms such as itching and dryness of scalp. Results of the study demonstrated that most patients treated with Hairzone solution showed a good response to the therapy. There was a significant improvement (P<.0001) in the condition of scalp with reduction in dandruff, denuded patches, and epidermal changes in all the 28 patients at the end of 6 weeks of treatment (Figure 1). None of the patients had any significant adverse effects during the entire study period and overall compliance to the treatment was adequate. Therefore, it can be concluded that Hairzone solution is clinically safe and effective in the management of diffuse hair loss.

Apr–Jun 2012 • Vol LI • No 4 • 5 Health Tips Product Feedback Eat Better L There is a massive amount of advice offered about what constitutes a healthy diet. The vast majority of this advice suggests to add or eliminate specific foods from plate. Most of us have heard the dogma that around 30% of calories should come from fat, about 10% to 15% from protein, and about 60% from carbohydrates. The reality is that it does not matter what percentage of calories in the diet come from fat or carbohydrates, within reason. A wide range of ratios work as long as a person gets sensible amount of all the vital nutrients required for maintaining good health. The real secret to healthy eating lies in the following 3 simple guidelines. Adhering to these basic rules will help to naturally adopt a more wholesome pattern of eating. Eat Real Food Whenever possible, consume foods that are whole, fresh, locally grown, and made with as little processing and packaging as possible. Real foods are delicious, nutrient-packed foods that are free of additives and other artificial ingredients, unrefined, and minimally processed. They include vegetables, fruits, legumes, whole grains, low-fat and fat-free dairy foods, fish, and lean meats. Eat a Little Less Women often ask how many calories they would require each day. There is no easy answer to this question; it depends on many factors. If a person is putting on additional pounds or needs to take off weight, he/she will have to reduce the intake of food. If a person is maintaining a healthy body weight, it indicates that he/ she is balancing energy intake well. It is a good idea to limit the portion size of meal. The brain requires about 20 minutes to register that the stomach is full, so give some time for the brain to keep up with what and how much of food is taken in. It would otherwise result in consumption of more calories than what is actually needed. Enjoy Your Meals iv.52 is quite effective for all types of liver disorders. It helps to alleviate vomiting during pregnancy and clear the bowels. Many challenging cases of itching during pregnancy, which is due to cholestasis, have been very well treated with Liv.52. Liv.52 is effective, easily available, and well-tolerated by patients including children. – Dr Premvati Faculty of Ayurveda, Institute of Medical Sciences Banaras Hindu University, Varanasi - 221001 Uttar Pradesh I am acquainted with Liv.52 for many years, and find unparalleled satisfaction with results. Antibiotic-induced hepatitis is a challenging case for the practicing physician. Patients get faster recovery when Liv.52 is prescribed as an adjuvant therapy. – Dr Khastagir BK Gupta Colony, Kolkata - 700126 West Bengal I have been prescribing Liv.52 DS successfully for many years. I have used the product personally also when I was suffering from jaundice. The response to the product is excellent, and the product is highly palatable. I have treated a resistant case of jaundice (due to cirrhosis of liver) successfully with Liv.52 DS. The product showed excellent response where other drugs had failed. – Dr Avnish Kumar Jain Bartala Yaadgaar, Saharanpur - 247001 Uttar Pradesh M y experience with Liv.52 is nearly 3 decades now, and I feel there is no better drug for liver disorders than Liv.52. I have treated many challenging cases of viral hepatitis and alcoholic fatty liver with Liv.52 successfully. – Dr Om Prakash Gupta 19, Samrat Lane, Pitampura - 110035 Delhi Eating is as much about satisfying your emotional and aesthetic needs as your nutritional ones. Enjoy sharing meals with family and friends. Create pleasant ceremonies around meals, no matter how simple. Focus on quality, not quantity. Savor each bite of the food rather than eating for fullness. –– Excerpted from: Health & Nutrition Letter. 2010;28(3):Suppl. 6 • Apr–Jun 2012 • Vol LI • No 4 www.himalayahealthcare.com Health News Driving After One Drink The blood alcohol limit for driving in the United States is 0.08%, but even blood alcohol levels as low as 0.01% increases the risk of a potentially deadly crash, according to a study published in Addiction in September. Drivers who had such low blood levels of alcohol and were only slightly tipsy tended to have more severe crashes than sober drivers, the analysis of national crash data revealed. Not only can just one drink impair driving skills and reaction times, but slightly “buzzed” drivers are also more likely to speed and not wear seat belts. That is why some countries have lower blood alcohol limits (0.03% in Japan and 0.02% in Sweden). –– Wellness Letter. 2012;28(4):8. Human Papilloma Virus Vaccine for Oral Cancer? The human papilloma virus (HPV) vaccine given to girls and young women to protect against cervical cancer may also protect against oral cancer. www.himalayahealthcare.com A recent study in the Journal of Clinical Oncology found that strains of HPV that cause cervical and anal cancer are causing an increasing number of cases of oral cancer—mostly in men, and usually of the tonsils and base of the tongue. For these cancers, the virus is believed to be transmitted via oral sex. Recently, a CDC advisory committee recommended that boys and young men should also be vaccinated to get protected against oral cancer. –– Wellness Letter. 2012;28(4):1. Take Blood Pressure Medication in the Evening If you take blood pressure medication, consider taking it in the evening, rather than the morning. A recent review from the Cochrane Collaboration evaluated 21 studies and found that taking the drugs in the evening results in slightly lower 24-hour blood pressure readings. In addition, a new Spanish study (published in Journal of the American Society of Nephrology) of people with hypertension and chronic kidney disease found that those who were told to take at least one hypertension drug at bedtime not only had better blood pressure control, but also had far fewer heart attacks, strokes, and other cardiovascular events over a 5-year period than those taking the drugs in the morning. –– Wellness Letter. 2012;28(4):8. Smoking and Breast Cancer Another reason for women to avoid smoking and secondhand smoke—they both increase the risk of breast cancer after menopause, according to an analysis of data from nearly 80,000 participants in the Women’s Health Initiative, published in British Medical Journal. Current smokers were 16% more likely than lifetime nonsmokers to develop breast cancer, with those smoking for many decades at the highest risk. An increased risk (averaging 9%) persisted for up to 20 years after women quit smoking. Women with the greatest exposure to secondhand smoke were also at increased risk. –– Wellness Letter. 2011;28(3):8. Coffee Okay for Hypertension Under Control It is okay to drink coffee, even if one has high blood pressure according to a recent review of studies involving people with hypertension. The studies on the acute effects found that in people who had abstained from caffeine for 9 to 48 hours, 2 cups of coffee (with 200 to 300 mg of caffeine) raised blood pressure 7 points, on average, for up to 3 hours. But in studies lasting 2 weeks, daily coffee intake did not increase blood pressure, probably because tolerance to caffeine develops in about a week. And longer observational studies found no link between habitual coffee consumption and cardiovascular risk. If hypertension is not under control, however, one should avoid high doses of caffeine, the researchers advised. –– Wellness Letter. 2011;28(3):8.

Aim The aim of this study was to conduct a meta-analysis on the efficacy and short- and long-term safety of Liv.52 as a hepatoprotective in tuberculosis (TB) patients receiving anti-TB drugs, as published in 8 controlled clinical trials. Materials and Methods A meta-analysis of 8 clinical studies conducted between 1970 and 1992 in 689 tubercular patients receiving antitubercular treatment (ATT) along with Liv.52 or placebo was taken up for this study (Table 1). Duration of the treatment varied from 4 weeks to 1 year. Children below the age of 2 years received 10 to 20 drops of Liv.52, 3 to 4 times daily. Children in the age group of 2 to 5 years received 20 drops of Liv.52, 3 times daily. Children aged >5 years and adults received 1 to 2 teaspoonfuls of Liv.52 syrup 3 times daily, or 1 to 2 tablets of Liv.52, 2 to 3 times daily. Improvement in various parameters of hepatotoxicity, such as hepatomegaly, anorexia, weight gain, general well-being, and liver function test (alanine aminotransferase [ALT]), and improvement in the ultrasonographic findings of the hepatobiliary system were taken into consideration. Changes in various parameters from baseline values and those at the end of the study were pooled and analyzed cumulatively using Fischer’s exact test or unpaired Students t test. Statistical analysis was performed using GraphPad Prism Software (version 4.03). Results Results of the meta-analysis showed a statistically significant improvement in hepatotoxicity in patients receiving anti-TB drugs and Liv.52. Significant improvements were observed in associated symptoms such as anorexia, weight gain, and hepatomegaly. The protective effect of Liv.52 against hepatotoxic reaction caused by ATT was further substantiated by a significant reduction in ALT values and alleviation of gastrointestinal symptoms due to hepatitis (Table 2).

These results suggest that chronic telogen effluvium may be secondary to a reduction in the variance of anagen and also this pathological state represents a new functional type of recurrent hair shedding. Clin Res Hepatol Gastroenterol. 2012;36(2):110-121. Autoimmune liver diseases include autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), and primary sclerosing cholangitis. Recurrent urinary tract infections (UTI) have been strongly associated with PBC, and to a lesser extent with AIH. These observations were initially based on the observation of significant bacteriuria in female patients with PBC. Larger epidemiological studies demonstrated that there was indeed a strong correlation between recurrent UTI and PBC. AIH has not been linked to recurrent UTI in epidemiological studies; however treatment of UTI with nitrofurantoin can induce AIH. As Escherichia coli is the most prevalent organism isolated in women with UTI, it has been suggested that molecular mimicry between microbial and human PDC-E2 (the main autoantigenic target in PBC) epitopes may explain the link between UTI and PBC. Chronic Telogen Effluvium is due to a Reduction in the Variance of Anagen Duration Gilmore S, Sinclair R. Australas J Dermatol. 2010;51(3):163-167. The authors of this study sought to investigate the follicular dynamics of chronic telogen effluvium and diffuse cyclical hair loss using a previously validated computer simulation known as the follicular automaton. They were able to simulate reductions in both the mean and variance of anagen duration, and thus investigate their consequences with respect to both hair volume and hair shedding. Results of the study showed that reducing the mean anagen duration results in loss of hair volume without prominent fluctuations in hair fall: findings that reproduced the key features in androgenetic alopecia. In contrast, a reduction in the variance of anagen duration generated follicular dynamics that accurately www.himalayahealthcare.com The Natural History of Acute Upper Respiratory Tract Infections in Children Mitra A, et al. Prim Health Care Res Dev. 2011;12(4):329-334. Acute upper respiratory tract infections (AURIs) in children are one of the most common reasons for people seeking advice from general practitioners (GPs); however, little is known about the natural history of AURIs in terms of the length and severity of symptoms, because the majority of illnesses are contracted at home. After an initial pilot study to test the feasibility of parents recording symptoms in a diary based on the Canadian Acute Respiratory Illness and Flu Scale (CARIFS), a random selection of primary schools operating in the region was carried out in order to minimize selection bias. Meetings were arranged at 20 schools to obtain written consent from parents and to give out diaries with a stamped addressed envelope. The diaries recorded daily symptom severity for one episode of AURI and the data were analyzed. Diaries were returned from 223 children, of whom 146 had had an AURI. The average age was 8 years, and there were almost equal numbers of boys and girls. The most frequent symptoms were runny nose, cough, feeling unwell, and sore throat. There was a biphasic distribution with systemic symptoms in the first 3 days characterized by fever, poor sleep, irritability, not playing, and headache. By day 4, symptoms localizing the infection to the upper respiratory tract appeared with runny nose, cough, sore throat, and poor appetite; these continued into the second and occasionally third week. Most symptoms lasted for 5 to 11 days, with a median length of 7 days for all symptoms. Symptoms defined by parents tended to be scored less for severity than symptoms defined by children. Apr–Jun 2012 • Vol LI • No 4 • 9 Fact File Fitness Climb Your Way to Health Resistance of Microorganisms Many of us actually do not have the time to exercise in a gym, as we are either busy at our workplace or follow a sedentary lifestyle. There is an option that keeps you in shape as well as boosts your stamina and general fitness—stair climbing. Avoid elevators and escalators and take the stairs! • Resistant micro-organisms cause infections that normally do not respond well to conventional treatment leading to prolonged illness and higher risk of death. • Resistant micro-organisms emerge, spread, and persist due to inappropriate and irrational use of antimicrobial drugs. • About 440,000 new cases of multidrug-resistant tuberculosis come into sight each year leading to at least 150,000 deaths. • Antimicrobial resistance to earlier generation antimalarial medications such as chloroquine and sulfadoxinepyrimethamine is prevalent in most malaria endemic countries. • Hospital-acquired infections are mainly because of the highly resistant strains of bacteria, particularly the methicillinresistant Staphylococcus aureus. Stair climbing is the most useful and least expensive workout that anybody can have. Walking up and down stairs is an effective exercise, as it burns up your calories and strengthens leg muscles. It also improves blood circulation and reduces risk of heart diseases. Making stair climbing a regular physical activity can help in shedding excess weight and maintaining healthy bones, joints, and muscles. For every 30 minutes spent in walking the stairs, you can burn up to 300 calories based on how intense the workout is. Stair climbing as an exercise can be started with 25 steps at a time and then slowly increased. It is found that climbing two steps at once exercises the major leg muscles (quadriceps) and the buttocks (gluteal muscles). Climbing stairs more beneficial than swimming According to a study, stair climbing burns out at least 250 percent of more calories than that is lost during swimming for the same duration. Climbing a flight of stairs 2 times a day regularly for a period of 1 year can help to lose up to 12 pounds. At the same time, there should be a monitored calorie intake. Promotion of stair climbing at workplace linked to greater effects in the overweight A study conducted in a 5-story building using an intervention such as posters promoting weight loss in the lobby and similar messages between floors, proved that there is a definite increase in stair climbing in a workplace owing to an intervention. The greater effect of the intervention among overweight individuals implies that stair climbing may be a type of acceptable physical activity or exercise for people who want to control their weight.

In an American history discussion group, the professor was trying to explain how society’s ideal of beauty changes with time. “For example,” he said, “Take the 1921 Miss America. She stood 5 feet 1 inch tall and weighed 108 pounds. How do you think she’d do in today’s version of the contest?” The class fell silent for a moment. Then one student piped up, “Not very well.” “John,” the new guy replied. The manager scowled. “Look, I don’t know what kind of a namby-pamby place you worked at before, but I don’t call anyone by their first name! It breeds familiarity and that leads to a breakdown in authority,” he said. “I refer to my employees by their last name only—Smith, Jones, Baker—that’s all. Now that we got that straight, what is your last name?” The new guy sighed and said, “Darling. My name is John Darling.” “Why is that?” asked the professor. “For one thing,” the student said, “She’d be way too old.” The manager said, “Okay, John, the next thing I want to tell you...” ••• Patient to optometrist: I’m very worried about the outcome of this operation, doctor. What are the chances? ••• Patient: Doctor, every time I eat fruit I get this strange urge to give people all my money. Doctor: Would you like an apple or a banana? ••• An elderly widow and widower were dating for about five years. The man finally decided to ask her to marry. She immediately said “yes”. Optometrist to patient: Don’t worry, you won’t be able to see the difference. ••• Teacher: What is the axis of the earth? The next morning when he awoke, he couldn’t remember what her answer was! “Was she happy? I think so, wait, no, she looked at me funnily...” Student: The axis of the earth is an imaginary line which passes from one pole to the other, and on which the earth revolves. After about an hour of trying to remember to no avail, he got on the telephone and gave her a call. Embarrassed, he admitted that he didn’t remember her answer to the marriage proposal. Student: Yes, Sir. “Oh”, she said, “I’m so glad you called. I remembered saying ‘yes’ to someone, but I couldn’t remember who it was.” Teacher: Very good. Now, could you hang clothes on that line? Teacher: Indeed, and what sort of clothes? Student: Imaginary clothes, Sir. ••• ••• “Now, Joseph,” said the teacher to the aggressive youngster, “What do you think your classmates would think of you if you were always kind and polite?” “They’d think they could beat me up,” promptly responded Joseph. ••• The manager of a large office asked a new employee to come into his office. “What is your name?” was the first thing the manager asked.
