Efficacy of ultrasound-guided transversus abdominis plane [TAP] block for postcesarean section delivery analgesia. A double-blind, placebo-controlled, randomized study

Ultrasound-guided transversus abdominis plane [TAP] block has been used for intra-operative and postoperative analgesia. Here we evaluate the efficacy of TAP block for postoperative cesarean delivery analgesia. A randomized, double-blind, placebo-controlled trial was performed at King Khalid University Hospital on 40 patients undergoing cesarean delivery under spinal anesthesia with bupivacaine and fentanyl. At the end of surgery they received bilateral ultrasound-guided TAP block either with bupivacaine 0.25% [B group] 20 patients, or saline [S group, or placebo group] 20 patients, followed by patient controlled analgesia with IV morphine only. Each patient was assessed 24 hours after delivery for pain, morphine consumption, nausea, vomiting, sedation, patient's satisfaction, and also pain relief during mobilization [24 hours post-cesarean section]. All 40 participants completed the study. Total morphine consumption was reduced more than 60% in the bupivacaine group; the bupivacaine group also reported improved satisfaction with their pain relief over 24 hours after surgery, reduced morphine consumption, less nausea, vomiting, and better patient's satisfaction. Ultrasound-guided TAP block improved postoperative analgesia, reduced morphine consumption and improved patient's satisfaction regarding analgesia after cesarean delivery

Age at menarche and the reproductive performance of Saudi women

Background: Saudi Arabia has undergone substantial development in the recent past with concomitant changes in living conditions, and economic and general health status that have affected the age at menarche in Saudi women. We evaluated the current age at menarche and reproductive events among Saudi women

Subjects and Methods: Age, age at menarche, age at marriage, age of first pregnancy, number of children, and number of abortions were collected for Saudi women attending King Khalid University Hospital [KKUH] over a 3-month period in 2002

Results: For 989 Saudi women, the mean age at menarche was 13.05 years. There was a decrease in the age of menarche over the past 20 years, an increase in the age of marriage, age of first pregnancy, and a decrease in the number of children and abortions. Compared with data from two decades, the age at menarche decreased significantly from 13.22 to 13.05 years

Conclusion: The decrease in the age of menarche among Saudi women indicates better socioeconomic status and improvements in health

Prevalence of osteoperosis among postmenopausal females with diabetes mellitus

To assess the prevalence of osteopenia and osteoporosis among Saudi postmenopausal women with non-insulin dependent type 2 diabetes mellitus [T2DM]. The study was carried out at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from February 2000 to September 2002. Bone mineral density [BMD] of the lumbar spine and femoral neck using dual x-ray absorptiometry [DXA; Lunar Wisconsin], were performed in 104 postmenopausal Saudi women with T2DM, and 101 postmenopausal non-diabetic women [control]. Bone mineral density was measured in gm/cm2 and both T-score and Z-score were measured but only T-score was used for analysis based on World Health Organization criteria. Bone profile, 25[OH] Vitamin D, 1,25[OH]2 Vitamin D, parathyroid hormone and urine deoxypyridinoline [DPD] were measured in most patients and controls. Body fat measurement around the biceps muscles using Futrex [body composition analyzer] were performed in patients and controls. Years postmenopausal, duration of diabetes mellitus, parity, exercise, sun exposure and milk consumption were also recorded. In the diabetic group, the mean spine BMD was 0.928 gm/cm2 [T-score = -2.28 SD] and for femoral neck the mean BMD was 0.817 gm/cm2 [T-score = -1.21 SD]. In control group, the mean spine BMD was 1.036 gm/cm2 [T-score = -1.2] and mean femoral neck BMD was 0.914 gm/cm2 [T-score = -0.608]. In the diabetic group, there was 16 [16.64%] patients with normal BMD of the spine, 42 patients [43.68%] with osteopenia [mean T-score = -1.8 SD] and 45 [46.8%] with osteoporosis [mean T-score = -3.3 SD]. Osteoporosis is more common among Type 2 postmenopausal females in this ethnic group. Since both groups are postmenopausal, having equal percentage of Vitamin D deficiency, multi-parity, non exposure to sun, lack of exercise and negligible milk intake, one can conclude that the low BMD can be attributed to DM in the absence of other causes of osteoporosis

Leptin concentration during different trimesters of pregnancy and its relation to other pregnancy hormones

To determine the levels of leptin and other pregnancy hormones [progesterone, estradiol, folliculi stimulating hormone, luteinizing hormone and beta human chorionic gonadotropin] in pregnant females during different stages of pregnancy and to correlate these levels to maternal weight, body mass index [BMI], babies weight and babies BMI. Leptin level and other pregnancy hormones were measured in 36 pregnant females and 30 non-pregnant females followed at King Khaled University Hospital, Riyadh, Kingdom of Saudi Arabia in the year 2001 in a prospective study. Blood samples were collected at the first, 2nd and 3rd trimester and after delivery. Correlation analysis between leptin level and pregnancy hormones, in addition to maternal weight, BMI, babies weight and BMI. The mean leptin levels during pregnancy and postnatally were significantly higher in pregnant females compared to the non-pregnant controls. Serum concentration of leptin increased significantly [p=0.01] in the pregnant females from 21.24 +/- 9 ng/ml during the first trimester to 26.3 +/- 8.69 ng/ml during the 2nd trimester, but insignificantly decreased to 23.29 +/- 8.62 ng/ml during the 3rd trimester [p=0.073]. After delivery leptin concentration significantly decreased to 17.36 +/- 7.95 ng/ml [p=0.0025]. The changes in levels of leptin during pregnancy were independent to other pregnancy hormones which showed a different pattern of variation. The changes in levels of leptin during pregnancy were independent to other pregnancy hormones which showed a different pattern of variation

Leptin level in pregnant mothers at term and cord blood and the effect of newborns gender

To evaluate the leptin level in healthy pregnant mothers at term and in their newborns and its relationship to their body mass index [BMI] and gender of the newborn. The leptin level was measured in serum of 187 pregnant women at term delivering at the King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia in July 2001 and their newborns. Correlation studies were made between leptin level and their growth parameters, and gender of the newborns. Leptin level of the mothers was significantly higher compared to their newborns. There was a significant correlation between leptin level in the pregnant women and their weight, BMI, and the newborns leptin level and weight, but not their height or BMI. A statistically significant difference was found between male and female newborns plasma leptin level. A significant correlation was found between male newborns leptin level and all their growth parameters, while in the female newborns there was no correlation between their leptin level and BMI. Leptin plays an important role in providing a growth promoting signal during pregnancy, but the fat mass does not seem to be the most important predictor of cord leptin level

Multiple pregnancy management: the King Khalid University Hospital experience

This review analyzes the multiple pregnancies in King Khalid University Hospital [KKUH] from January 1985 to December 1989. Over this period, the incidence of multiple pregnancy was found to be 10.25/1000. The study confirms a higher incidence of complications among multiple pregnancy cases. For example, the cesarean section rate was 32.2% as compared with 3.6% for the single pregnancies, and the neonatal deaths occurred in a higher number [3.3%] as compared to 1.0% in the controls. However, even though the overall prematurity rate [
