Role of national blood transfusion service (NBTS) in promoting emergency obstetrics care (EMOC)

Background: Obstetrics haemorrhage is one of the leading cause of maternal mortality in our settings, this was compounded by the non availability to safe blood in situation of need. Hence the prompt access and availability of blood can avert this preventable cause of maternal death. Objectives: to highlight the benefits of effective collaboration with NBTS in ensuring prompt availability of blood for emergency obstetric services requiring blood for transfusion. Material And Method: All obstetrics cases requiring blood transfusion in FMC Nguru from 1st stJanuary 2006 ­ 31 December 2011 were retrospectively reviewed. Trends and pattern of the st strequest and source of blood were looked at within the two periods (from 1 January 2006 ­ 31 st stDecember 2008 and 1 January 2009 ­ 31 December 2011). Records of 1634 obstetric patients requiring blood transfusion or received blood transfusion in the maternity units were retrieved from the medical records, maternity ward record and blood bank. Information pertaining to their age, parity, indication for the transfusion or requests and source of blood was obtained for analysis. Data was analysed using simple percentage. st st Results: Between 1 January 2006 and 31 December 2008 only 513 (56%) of the units requested st st907 units of blood were supplied, while between 1 January 2009 and 1 December 2011 1367 ( 87%) of the 1567 units of blood requested were supplied. Within the earlier study period the only available source were from willing relatives and commercial blood donors, however between 2009 and 2011 more than 2/3 (64.2%) were supplied from the north east zonal NBTS office in Maiduguri. In 2006 through 2008, donation from relatives and commercial donors accounted for 53.22% and 46.78% respectively, but in 2009 and 2011 donation from relatives and commercial donors were recorded as 23.9% and 11.6% respectively. The commonest indication for the requests were anaemia, obstetrics haemorrhage (PPH, APH) and emergency C/S. Conclusion: Ready available source of blood will significantly improve timely availability of blood in our setting. There is the need to encourage this collaboration in other regions to ensure prompt availability of blood to attend to emergencies requiring blood transfusion

Utilization of Insecticide Treated Nets among Pregnant Women Attending Antenatal Clinic in a Suburban Referral Hospital, North-East Nigeria.

Aim: The aim of this study was to assess the knowledge and usage of ITNs among pregnant women attending antenatal clinic in a referral health facility in Nigeria. Materials and Methods: This was a cross-sectional study carried out at the antenatal clinic of the Federal Medical Centre Azare, North-East Nigeria between October and December 2012. A structured questionnaire was administered on consenting consecutive pregnant women until the sample size was reached. Data obtained were analysed and associations were compared using 2 and Fisher’s exact test where applicable, with Pvalue <0.05 considered significant. Results: A total of 197 pregnant women were recruited and interviewed. The maternal age ranged from 17-45 years with mean age of 24.2±5.5 years while the parity ranged from 0-11 with multipara constituting 95 (48.22%) and grand multipara, 29 (14.72%). While only 31 (15.74%) of the respondents had tertiary level of education, 64(32.49%) and 15(7.61%) of them had secondary and primary levels of education respectively. Twenty five (12.69%) had no formal education. Majority of the clients, 162 (82.23%) were unemployed, 14 (7.11%) were civil servants and 17 (8.63%) were petty traders. Although most of the women, 189 (95.94%), had knowledge of ITNs, only 132 (67.01%) owned them and much less, 97 (49.24%), used them. Para 5 and above were significantly more likely to use ITNs than para 1-4 and para 0 (2=21.118; P=0.03). Age, educational status, occupation, ethnic groups and religion (2=1.084; P=0.30) did not influence the use of ITNs. Thirty two (32.00%) and 23 (23.00%) of the ITN non-users gave heat and poverty respectively, as reasons for non utilization. Conclusion: Only few of the clients studied utilized ITNs mainly because of heat and poverty. Education of pregnant women to correct the myths associated with the use of ITNs will improve compliance rate.

Prevalence of hyponatremia in acute medical admissions in tropical Asia Pacific Australia

OBJECTIVE@#To determine prevalence of hyponatremia in acute medical admissions in Northern Australasia.@*METHODS@#We studied 469 consecutive acute medical admissions to a hospital in Australia's Far North Queensland during the colder months of June and July 2012. Prevalence of hyponatremia and its relationship with gender, age, diagnosis and prognosis in acute medical admissions were investigated.@*RESULTS@#On admission, hyponatremia (plasma sodium <136 mmol/L) was present in 39.4% of patients, with mild (130-135 mmol/L), moderate (126-129 mmol/L) and severe (<126 mmol/L) hyponatremia being present in 25.2%, 10.7% and 3.6% respectively. Overall, adding together admission hyponatremia with that developing during admission, 45.2% of patients were affected with 11.5% moderate hyponatremia cases and 4.1% severe ones. Hypokalemia and hyperkalemia were present in 17.0% and 18.1%, respectively. Overall, 275/469 patients (58.6%) presented with an electrolyte abnormality. There were significant correlations of hyponatremia with age but not with gender and in-hospital mortality. Prevalence of hyponatremia was high across all diagnostic categories.@*CONCLUSIONS@#The prevalence of hyponatremia appears to be high in the tropical North Australian population, being the highest prevalence reported amongst acute hospital admissions. The previously reported correlations with age and mortality do appear to hold good for this population with a high prevalence of electrolyte disorders. Further prospective analysis on a larger population in the area is needed to confirm our findings.

Diabetes epidemic in the Asia Pacific region: has hemoglobin A1C finally earned its place as a diagnostic tool?

Two-third of the world's population lives in the Asia Pacific region where prevalence of diabetes has reached epidemic proportion. With China and India being the most populous nations on the globe, it is believed that over 150 million diabetes reside in the region with more than 95% being of type 2 diabetes mellitus (T2DM). Furthermore, other Pacific islands in the region have high rates of T2DM including Tonga, Fiji, French Polynesia, and Nauru. The latter has the highest prevalence of T2DM per population in the world. Over the past two decades, in Australia and New Zealand, the prevalence of T2DM has more than doubled, mainly amongst the Aboriginal and Torres Strait Islander and Maori peoples respectively. With the increasing prevalence of diabetes in the Asia Pacific region coupled with the limited number of resources, use of a reliable and effective mode of diagnosis for T2DM is warranted. Yet to date, only New Zealand has adopted the American Diabetes Association recommendation of using hemoglobin A1C in the diagnosis of the disease. The aim of this review is to discuss the clinical usefulness of hemoglobin A1C and highlight its diagnostic role in the Asia Pacific region where T2DM is increasingly encountered.

Gas Chromatography-Mass Spectrometry (GC-MS) Analysis of Bioactive Components of Ethyl acetate Root Extract of Guiera senegalensis J.F. Gmel.

Guiera senegalensis J.F. Gmel is used in West African Ethnomedicine for treating diarrhoea, dysentery, malaria, cough and microbial infections. The methanol and ethyl acetate root extracts of G. senegalensis have been shown to be effective against diarrhoea and also have antibacterial activity. The plant was therefore investigated for its bioactive components. The ethyl acetate root extract was investigated using Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Nine components were identified, n-Hexadecanoic acid (46.6%) as the major component followed by 9-Hexadecenoic acid (20.93%), methyl ester (7.75%), 7- Octadecenoic acid- methyl ester, 1, 2-benzene dicarboxylic acid – diisoctyl ester having (6.97%) respectively; 2–pentanone - 4–hydroxy–4–methyl acid diethyl phthalate (2.32%), Decane–6–ethyl–2–methyl and nonane, 3– 7–dimethyl with (1.55%) compositions respectively.

Growth hormone deficiency short stature in a third world adult endocrine clinic: Usefulness of clonidine test in its diagnosis.

Background: Short stature (SS) can be treatable; yet the diagnostic value of a simple test in correctly identifying the two common etiologies in developing countries, viz., growth hormone deficiency (GHD) and normal variant short stature (NVSS), has not been reported in a typical third world population. Objectives: The aim of the study was to evaluate the reliability of clonidine test in differentiating short stature caused by GHD from NVSS. Settings and Design: Data of subjects evaluated for growth hormone deficiency SS at a Saudi Arabian university hospital were retrospectively reviewed. Materials and Methods: Clonidine and insulin tolerance tests (ITT) were conducted on 60 subjects aged 12 years and above with SS, while peak stimulated growth hormone cut off value of < 10 microg/l was used to diagnose GHD. Statistical Analysis: Sensitivity and specificity for clonidine test and ITT were computed, while receiver operator characteristic (ROC) curves were constructed from the results in order to assess the diagnostic usefulness of the two tests. Mann-Whitney test was used to determine level of significance. RESULTS: Clonidine test showed superior sensitivity and specificity, viz., 81% and 82%, as against 65% and 59% for ITT respectively. Overall, the efficiency of clonidine test in correctly differentiating short stature caused by GHD from NVSS was higher, viz., 90%, compared to ITT's 77%. Conclusions: Clonidine test proved to be an excellent test for initial assessment of GHD and may be used as a screening test for short stature in third world countries.

Apolipoprotein B/apolipoprotein A-I ratio in relation to various definitions of metabolic syndrome among Saudi patients with type 2 diabetes mellitus

To assess if the apolipoprotein Apo B/Apo A-I ratio in Saudi patients with type 2 diabetes mellitus T2DM is associated with metabolic syndrome MetS. This cross-sectional study was conducted on 250 patients with T2DM, above 40 years of age, at King Abdulaziz University Hospital Diabetes Center in Riyadh, Saudi Arabia, between January and December 2006. Metabolic syndrome was defined, and compared according to 3 criteria, namely, National Cholesterol Education Program Adult Treatment Panel III, International Diabetes Federation, and World Health Organization. In the 250 patients studied, all 3 definitions demonstrated significant increase in the Apo B/Apo A-I ratio, in Saudi type 2 diabetics with the MetS. There was a strong positive correlation between the Apo B/Apo A-I ratio and triglycerides, low-density lipoprotein cholesterol, and total cholesterol r=0.43-0.54, p<0.0001, and a weak, yet significant, correlation r=0.14-0.21, p<0.05 with waist circumference, waist-hip ratio, fasting glucose, and hemoglobin A1c, however, not with body mass index r=0.01, p=0.88. In contrast, the ratio showed strong negative correlation with high-density lipoprotein cholesterol r = -0.7, p < 0.0001. Apolipoprotein B/apolipoprotein A-I ratio is significantly associated with MetS in Saudi patients with T2DM, similar to observations made in other ethnic groups

Hirsutism in Saudi females of reproductive age: a hospital-based study

Hirsutism among women of fertile age is commonly seen in clinical practice, but the pattern of the disease in Saudi Arabs has not been studied. The aim of the study was to determine the clinical, biochemical and etiologic features of hirsutism in Saudi females. 101 Saudi Arab women presenting with hirsutism at King Khalid University Hospital, Riyadh, Saudi Arabia, from 1 January 2000 to 31 December 2005 were prospectively assessed using the recently approved diagnostic guidelines for hyperandrogenic women with hirsutism. Polycystic ovary syndrome [PCOS] was the cause of hirsutism in 83 patients [82%] followed by idiopathic hirsutism [IH] in 11 patients [11%]. Others causes of hirsutism included late onset congenital adrenal hyperplasia in 4 patients [4%], microprolactinoma in 2 [2%] and Cushing's syndrome in 1 [1%] patient. Age at presentation of PCOS was 24.5_6.6 years [mean +/- SD] and 51% of the subjects were obese. Furthermore, 74 [89%] of patients with PCOS had an oligo/anovulatory cycle while the remaining 9 patients [11%] maintained normal regular menstrual cycle. Luteinizing hormone and total testosterone were significantly higher in patients with PCOS than in those with IH [P<.05]. The present data show PCOS to be the commonest cause of hirsutism in our clinical practice and PCOS is prominent amongst young obese females. However, further studies on a larger scale are needed to verify our findings

Treatment of Graves' hyperthyroidism - prognostic factors for outcome

To determine whether clinical and biochemical features of Graves' disease at presentation predict response to medical and radioiodine treatment. We carried out a retrospective 10-year study of 194 consecutive Saudi subjects with Graves' disease who were treated with antithyroid drugs, radioiodine therapy, or both, between January 1995 and December 2004 at King Khalid University Hospital, Riyadh, Saudi Arabia. At diagnosis, the mean age was 32 +/- 0.9 years. Only 26% of patients had successful outcome after a course of antithyroid medication. None of the clinical or biochemical factors were associated with a favorable outcome of antithyroid treatment. One dose of radioiodine [13-15 mCi [481-555 MBq]] cured hyperthyroidism in 83% of patients. Presence of ophthalmopathy at presentation was shown to be a significant contributing factor to failure to respond to a single dose of radioiodine [odds ratio, 6.4; 95% CI, 1.51-24.4; p<0.01]. Failure of radioiodine treatment was also associated with higher serum free T3 concentration at presentation [p=0.003]. In patients with Graves' hyperthyroidism, radioiodine treatment is associated with higher success rate than antithyroid drugs. A dose of 13-15 mCi [481-555 MBq] seems to be practical and effective, and should be considered as first line therapy. Patients with high free T3 concentration and, those with ophthalmopathy at presentation were more likely to fail radioiodine treatment. A higher dose of radioiodine may be advisable in such patients

Phytochemical; Analgesic and Anti-Inflammatory Effects of the Ethylacetate Extract of the Leaves of Pseudocedrella Kotschyii

Phytochemical screening was carried out on the ethylacetate portion of the ethanolic extract of the leaves of Pseudocedrella kotschyii and then evaluated for its analgesic (acetic acid-induced writhing) and anti-inflammatory (raw egg albumin-induced oedema) activities in mice and rats respectively. Phytochemical screening of the ethylacetate partition portion of ethanolic extract revealed the presence of flavonoids; glycosides and tannins as major chemical constituents. Alkaloids saponins; cardiac glycosides; steroids were not dictated in the extract. The ethylacetate extract (50 and 100 mg/kg i.p) exhibited significant activity (p0.05) against acetic acid-induced writhing in a dose dependent manner. In the anti-inflammatory activity the ethylacetate extract (50 and 100 mg/kg i.p.) caused a slight effect against the raw egg albumin-induced oedema. The effect was however observed not to be dose dependent. All these effects were compared with standard drug piroxicam (20 mg/kg i.p.)
