Gastroprotective effect of cardamom, Elettaria cardamomum Maton. fruits in rats.

Cardamom, the fruits of Elettaria cardamomum Maton. (Zingiberaceae) commonly known as "Heel khurd" is used in Unani system of medicine to treat gastrointestinal disorders. A crude methanolic extract (TM), essential oil (EO), petroleum ether soluble (PS) and insoluble (PI) fractions of methanolic extract, were studied in rats at doses of 100-500, 12.5-50, 12.5-150 and 450 mg/kg, respectively for their ability to inhibit the gastric lesions induced by aspirin, ethanol and pylorous ligature. In addition their effects on wall mucus and gastric acid output were recorded. All fractions (TM, EO, PS, PI) significantly inhibited gastric lesions induced by ethanol and aspirin but not those induced by pylorus ligation. TM proved to be active reducing lesions by about 70% in the EtOH-induced ulcer model at 500 mg/kg. The PS fraction reduced the lesions by 50% at 50 and 100mg/kg (no dose response was observed) with similar effect than the PI fraction at 450 mg/kg. In the aspirin-induced gastric ulcer, the best gastroprotective effect was found in the PS fraction, which inhibited lesions by nearly 100% at 12.5mg/kg. In our experimental conditions, the PS extract at doses >or=12.5mg/kg proved to be more active than ranitidine at 50mg/kg.

The burden of diabetes and impaired fasting glucose in India using the ADA 1997 criteria: prevalence of diabetes in India study (PODIS).

This random multistage cross sectional population survey was undertaken to determine the prevalence of diabetes mellitus (DM) and impaired fasting glycemia/glucose (IFG) in subjects aged 25 years and above in India. The study was carried out in 108 centers (49 urban and 59 rural) to reflect the size and heterogeneity of the Indian population. 41,270 (20,534 males and 20,736 females) subjects were studied. 21,516 (10,865 males and 10,651 females) were from urban areas and 19,754 (9669 males and 10,085 females) from rural areas. Blood samples were taken after a fast of 10-12h and the subjects were categorized as having IFG or DM using the 1997 American Diabetes Association criteria. The age and gender standardized prevalence rate for DM and IFG in the total Indian population was 3.3 and 3.6% respectively (P < 0.001). The standardized prevalence of DM and IFG in urban areas was significantly higher than that for the rural population (urban DM prevalence 4.6% versus rural DM prevalence 1.9%, P < 0.001; urban IFG prevalence 4.8% versus rural IFG prevalence 2.5%, P < 0.001). There was no statistically significant difference in the prevalence between DM (4.6%) and IFG (4.8%) in the urban population. The rural prevalence of IFG (2.5%) was significantly (P <0.001) more than the rural prevalence of DM (1.9%). Type 2 diabetes is a major health problem is India.

The burden of diabetes and impaired glucose tolerance in India using the WHO 1999 criteria: prevalence of diabetes in India study (PODIS).

This random multistage cross-sectional population survey was undertaken to determine the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in subjects aged 25 years and above in India. The study was carried out in 77 centers (40 urban and 37 rural). 18363 (9008 males and 9355 females) subjects were studied. 10617 (5379 males and 5238 females) were from urban areas and 7746 (3629 males and 4117 females) from rural areas. Blood samples were taken after a fast of 10-12 h and 2 h after 75 g of oral glucose. Subjects were categorized as having IGT or DM using the World Health Organisation (WHO) (1999) criteria. The standardized prevalence rate for DM in the total Indian, urban and rural populations was 4.3, 5.9 and 2.7%, respectively. The corresponding IGT rates in the three populations was 5.2, 6.3 and 3.7%, respectively. The urban prevalence of DM and IGT was significantly greater than in the rural population (P < 0.001 in both instances). The prevalence of DM was significantly, more than that of IGT (P < 0.001) within both the rural and urban populations. Type 2 diabetes is a major health problem is India.

Comparing the ADA 1997 and the WHO 1999 criteria: Prevalence of Diabetes in India Study.

This random multistage cross-sectional population survey was undertaken to determine the prevalence of type 2 diabetes mellitus (DM) in subjects aged 25 years and above in India. The study was carried out in 77 centres (42 urban and 35 rural) to reflect the size and heterogeneity of the Indian population. 18,363 (9008 male and 9355 female) subjects were studied. 10,617 (5379 males and 5238 females) were from urban areas and 7746 (3629 males and 4117 females) from rural areas. Blood samples were taken after a fast of 10-12 and 2 h after 75 g of oral glucose. Subjects were categorized as having impaired fasting glycemia (IFG) or DM using the 1997 ADA or having impaired glucose tolerance (IGT) or DM using the 1999 WHO criteria. The age- and gender-standardized prevalence rate for DM using the ADA criteria was 3.6% whilst that using the WHO criteria was 4.3% (P < 0.001). The respective standardized prevalence of DM, using the two criteria was, 4.7 and 5.6%, respectively (P < 0.001) in the urban Indian population and 2.0 and 2.7% (P < 0.02) in the rural Indian population. Using the WHO criteria, 581 subjects were newly diagnosed whilst the ADA criteria newly diagnosed 437 subjects. The respective numbers for the urban population were 425 and 323, and for the rural population were 146 and 114, respectively. The ADA criteria could diagnose 75.2, 76.0 and 73.0% of the subjects who had DM as per the WHO criteria. Of 739 Indian subjects who had IFG, 106 (14.3%) were diagnosed as having DM by the WHO criteria whilst 505 (68.3%) had values compatible with a diagnosis of IGT. Of the 536 urban subjects with IFG, 74 (13.8%) had DM and 350 (65.3%) had IGT using the WHO criteria. Of the 302 rural subjects with IFG, 32 (15.8%) had DM and 155 (76.3%) had IGT using the WHO criteria. 505 (49.9%) of 1012 Indian subjects with IGT as per the WHO criteria had IFG. 350 (47.7%) of 733 urban subjects and 155 (55.5%) of 279 rural subjects with IGT had values compatible with IFG as per the ADA criteria. Type 2 diabetes is a major health problem is India. The use of the ADA criteria would underestimate the prevalence of DM by not diagnosing subjects showing a poor response to a glucose challenge. This along with the discrepancies between subjects showing IGF or IGT could be a challenge to any prevention program.

High and low dose oxytocin in augmentation of labor.

OBJECTIVE: To compare the efficacy and safety of high dose oxytocin in the augmentation of labor. METHOD: Two hundred pregnant women requiring augmentation of labor were randomly assigned to receive oxytocin by either a low dose protocol (1.5 microm/min initially, increased by 1.5 microm/min every 30 min) or a high dose protocol (4.5 microm/min initially, increased by 4.5 microm/min every 30 min). RESULTS: High dose of oxytocin was associated with a significant shortening of labor 4 (1.10-10) vs. 6 (1-10) h, p<0.0001 without a significant difference in cesarean delivery rate, neonatal and maternal outcome. CONCLUSION: The use of high dose oxytocin is associated with significantly shorter labor without any adverse fetal and maternal effects.

A rare case of chondrosarcoma of the clavicle.

Although all types of tumour and tumour-like conditions have been described to occur in the clavicle, they only contribute to less then 0.5% of all skeletal tumours. The incidence of primary chondrosarcoma of the clavicle is extremely rare. To our knowledge it has not been reported in Malaysia. We would like to highlight the possibility of chondrosarcoma as a differential diagnosis for a clavicular lesion.

Leber's congenital amaurosis with anterior keratoconus in Pakistani families is caused by the Trp278X mutation in the AIPL1 gene on 17p.

BACKGROUND: Leber's congenital amaurosis (LCA) represents the earliest and severest form of retinal dystrophy leading to congenital blindness. A total of 20% of children attending blind schools have this disease. LCA has a multigenic basis and is proving central to our understanding of the development of the retina. We describe the clinical and molecular genetic features of four inbred pedigrees from neighbouring remote villages in northern Pakistan, in which some of the affected members have concurrent keratoconus. METHODS: History-taking and physical and eye examinations were performed in the field. Venipuncture, DNA extraction, studies of linkage to known LCA genes, automated sequencing and polymorphism analyses for haplotype assessments were done. RESULTS: We examined 12 affected and 15 unaffected family members. By history, there were an additional nine blind people in the four pedigrees. In each pedigree a consanguineous marriage was evident. We found a homozygous nonsense mutation in the AIPL1 gene, which replaces a tryptophan with a stop codon (Trp278X). The phenotype is severe and variable, despite the common molecular genetic etiology in each family. Affected patients had hand motion to no light perception vision and fundus findings ranging from maculopathy to diffuse pigmentary retinopathy. Three affected members had definite keratoconus, and two were suspects based on mild cone formation in the cornea of at least one eye. INTERPRETATION: We have identified four Pakistani families with a severe form of LCA that is associated with severe keratoconus in some affected members. The molecular etiology in all four families is a homozygous nonsense mutation, Trp278X, in the photoreceptor-pineal gene AIPL1. To our knowledge, this is one of the first phenotype-genotype correlations of AIPL1-associated LCA.

The story of Lot and the Qur'ăn's perception of the mortality of same-sex sexuality.

Discussion of the morality of same-sex sexuality in Islam is beginning to come to the forefront. It is a controversial topic that evokes differing views in Islam and, as such, needs to be addressed and understood. This study narrows the scope of the investigation to the use of moral terminology in the Lot story and elsewhere in the Qur'ăn. The method of semantic analysis that shall be applied is similar to the one espoused by Toshihiko Izutsu. In order to acquire a better understanding of how same-sex practices are qualified morally in the Qur'ăn, same-sex activities shall also be looked at in comparison to other opposite-sex and non-sexual practices. It is my contention that, in the Qur'ăn, same-sex practices are viewed no differently from certain opposite-sex and non-sexual activities. In quoting from the Qur'ăn, I will give my own translation of the Arabic terms that shall be analyzed. In general, however, I adopt Qur'ănic passages from Arthur J. Arberry, The Koran Interpreted, and where necessary, modify Qur'ănic passages with my own translations. I will also use Arberry's verse numbering, following that of Flügel.

Helicobacter pylori and intestinal metaplasia with its subtypes in the gastric antrum in a Saudi population.

BACKGROUND: There is a close association between intestinal metaplasia (IM) and the development of gastric cancer as well as a relationship between Helicobacter pylori, IM, and gastric cancer. Our aim was to study the frequency and subtypes of IM in a Saudi population with dyspepsia, a population with a low prevalence of gastric cancer. METHODS: Endoscopic antral biopsy specimens were histologically studied for the presence of IM and H. pylori in consecutive patients who underwent upper gastrointestinal endoscopy for evaluation of dyspepsia. Hematoxylin and eosin and Giemsa stain were used to study IM, inflammation, and H. pylori, whereas Alcian blue, pH 2.5/periodic acid-Schiff and high iron diamine/Alcian blue, pH 2.5, were used to study IM subtypes. RESULTS: Seven hundred and seventy-eight consecutive patients were recruited in this study, 415 men and 363 women, with a mean age of 43 +/- 17.6 years. Of the 778 patients, IM was identified in 118 (15.2%). The mean ages of patients with IM (48.8 +/- 18.7) and without IM (41.9 +/- 17.4) were statistically significant (P < 0.0001), whereas the patients' sex did not influence the presence of IM. Most had type-I IM (59.3%), whereas 26.3% and 14.4% had types II and III, respectively. The overall rate of infection with H. pylori was 75.4%. There was no difference in the frequency of IM in patients with or without H. pylori (15.5% versus 14.1%; P = 0.65). Of the 118 patients with IM, the 91 patients (77.1%) who also had H. pylori were older (55 +/- 23 years) than those without H. pylori (47 +/- 17 years, P = 0.05). CONCLUSION: This study has documented mainly that the prevalence of IM and IM subtype III is low in our population. Furthermore, we found no significant relationship between a high rate of H. pylori infection with either IM in general or with IM subtype III in particular, possibly accounting for a low incidence of gastric cancer in the Saudi population.

Wegener's granulomatosis. First case report in Bahrain.

Formerly a fatal condition, Wegener's granulomatosis is now treated with good results. Although the annual incidence of Wegener's granulomatosis in the general population is not known, most European and American studies revealed an incidence in the range of one for every 250,000 of the population. The estimated total population of Bahrain as of June 1997 is 586,110; here we report the first diagnosed case of Wegener's granulomatosis in Bahrain. Our patient presented with epistaxis, and from the clinical features, the very high ESR, the operative, histopathological and the radiological findings, and a high index of suspicion we could confirm the diagnosis along with the appropriate immunological test (positive cANCA). Standard treatment with cytotoxic agents and corticosteroids has been used. On follow-up the patient has shown a progressive improvement in her clinical and laboratory parameters.

Lower-extremity saphenous vein transposition arteriovenous fistula: an alternative for hemodialysis access in AIDS patients.

Arteriovenous access for long-term hemodialysis in patients with the acquired immunodeficiency syndrome (AIDS) represents a special challenge. Many of these patients are chronic intravenous drug abusers and do not have patent superficial upper-extremity veins available for conventional arteriovenous fistulas. This group of patients is also particularly prone to infections, which contraindicates the use of prosthetic grafts. Over a period of 13 months, five lower-extremity saphenous vein transposition arteriovenous fistulas (SVTAFs) were performed. Four patients had a diagnosis of AIDS at the time of operation; all of these were intravenous drug abusers. Three patients were male, two were female, and their age ranged from 34 to 66 years (mean, 48). Three patients had a SVTAF as their first hemodialysis access, and in two it was performed after multiple failed upper-extremity accesses. Four fistulas remain patent to date, after a mean follow-up of 11 months (range, 4 weeks to 16 months). One fistula thrombosed 4 weeks postoperatively, due to a hematoma that occurred after premature venipuncture for dialysis. There were no other major complications. We conclude that SVTAF is a suitable alternative to the limited hemodialysis venous access sites, especially in the AIDS population.

Familial hyperamylasaemia.

A six year old boy underwent extensive investigation for recurrent abdominal pain and was found to have a persistently raised serum amylase. Endoscopic retrograde cholangiopancreatography was normal and macroamylasaemia was excluded. Serum amylase concentrations were found to be raised in other family members spanning three generations, all of whom were asymptomatic. Clearance studies suggested no evidence of a renal tubular defect and serum lipase concentrations were normal. This is the first report of apparently familial hyperamylasaemia and the mode of inheritance is consistent with an autosomal dominant pattern.

Non-neoplastic changes in gastric antrum: are they different in distally located intestinal and diffuse-type gastric adenocarcinoma?

A total of 126 cases of primary adenocarcinoma of distal (antrum and/or adjacent body) stomach were reviewed. These cases were collected from the histopathology laboratory of Asir Central Hospital, Southwestern Saudi Arabia over an 8 year period (1987-94). Only gastrectomy specimens with non-neoplastic antral mucosa available for histological examination were included. Of 126 cases, 85 (67.5%) were of the intestinal type and 41 (32.5%) were of the diffuse type. Histological examination of the non-neoplastic antral mucosa showed: gastritis in 100% of these cases; Helicobacter pylori in 103/126 cases (81.8%); multifocal atrophic gastritis (MAG) in 53/126 cases (42.1%); intestinal metaplasia (IM) in 62/126 (49.2%); and type III intestinal metaplasia in 30/62 cases (47.7%). None of these non-neoplastic changes of antral mucosa was significantly different when the prevalence of these changes in intestinal and diffuse type gastric adenocarcinoma were compared using the chi 2 test. The prevalence of these non-neoplastic lesions were calculated in a 126 dyspeptic age- and sex-matched control patients and were as follows: H. pylori 91%; gastritis 78%; MAG 7.4%; IM 19% and type III IM 1.6%. The prevalence of H. pylori bacilli and gastritis was not significantly different between the cancer patients and the controls. The prevalence of MAG, IM and type III IM was significantly higher among cancer patients compared with the control group.

[Screening for scoliosis in western Galilee schools].

Scoliosis screening is still under debate. It is generally agreed that it is not cost-effective, but some still favor it as integral to preventive medicine. Among 2940 school children, aged 9 - 13, from several Moslem-Arab villages in the western Galilee, 55 (1.9%) were found to have some deformity on physical examination and were referred for spinal X-ray. Of these, 24 were X-rayed and in 20 of them there was a scoliosis of more than 7 degrees. The prevalence of in-family marriage in those with deformities was 31%, not significantly different from the 35% found in their communities. Using the worst-case analysis, the Moslem-Arab population of western Galilee cannot be regarded as a population at risk for scoliosis. Considering the poor cooperation of the parents with further investigation, we conclude that scoliosis screening should not be performed in this community.
