Torsion of an Ovarian Cyst in Pregnancy

Torsion of the ovary is the partial or total rotation of the ovary over its pedicle. It is unusual for it to occur in the second trimester. We report a case  of a 35year old G10P9+0A7 at 17weeks gestation who presented with acute severe abdominal pain. She was found to have an ovarian cyst in pregnancy. She had Exploratory Laparotomy where a huge gangrenous cyst was found and Salpingoophorectomy was performed. The pregnancy continued without any problems. The histology report showed a Simple Cyst. Key words: Torsion, Ovarian Cyst, Pregnanc

Chloroquine-resistant Plasmodium falciparum in Sokoto, North Western Nigeria

Three patients, 30, 2 and one and a half years, were diagnosed as having falciparum malaria and were placed on chloroquine therapy which failed. They were then placed on quinine therapy that then cleared the parasitaemia. This case report seeks to draw the attention of the presence of possible chloroquine-resistant falciparum malaria in Sokoto, North Western Nigeria.

Determinants of mother to child transmission of HIV among HIV exposed infants managed in Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria

Background: Mother to child transmission of HIV (MTCT) is globally known to be the major route of spread of HIV to the unborn fetus and neonate. Many factors related to the mother, infant or the type of HIV virus interplay to increase the risk of MTCT of the virus. Antepartum antiretroviral drugs administration reduces the maternal viral load therefore lowering   the risk of transmission. The objective is to determine infection rate and assess determinants of MTCT of HIV exposed infants delivered in UDUTH Sokoto.Methods: It was a 5-year retrospective study. Records of all HIV positive pregnant women and their babies managed in UDUTH were reviewed from the E health system of the hospital. Patient’s details were recorded from booking to delivery for the period under study. The infant’s records were retrieved and information from delivery to 18 months post-delivery obtained. Structured data collection tool was developed to compile the required information. Data was analyzed using SPSS IBMS 22. Descriptive statistics and comparisons between variables were made statistically using Chi square. P value of   ≤ 0.005 was considered as significant.Results: Records of all the patients recruited were all available for evaluation because authors use the E-health system of records keeping in our hospital. MTCT rate was 0.92%. Majority 60 (47.2%) were within age group 26-30yrs. The subjects were predominantly house wives 97(71.4%) and multipara 77 (60.6%). Viral load ranged between 112 to 28228 copies/ml. Twenty-two (17.3%) had CD4 count less than 250 cells/µl while 61 (48%) had counts above 500cells/µl. All were in WHO clinical stage 1-3. All were on triple regimen anti-retroviral drugs. Spontaneous rupture of membranes for over 4 hours occurred in 51(32%). Vaginal delivery was recorded in 89.7%. Breast feeding was practiced by 48%.Conclusions: Breast-feeding still remains a risk factor for MTCT OF HIV Early administration of   maternal antiretroviral drugs significantly reduces the rate of mother to child transmission of HIV

High nitrate levels in skeletal muscle contribute to nitric oxide generation via a nitrate/nitrite reductive pathway in mice that lack the nNOS enzyme

Introduction:Nitric oxide (NO) is a vasodilator gas that plays a critical role in mitochondrial respiration and skeletal muscle function. NO is endogenously generated by NO synthases: neuronal NO synthase (nNOS), endothelial NO synthase (eNOS), or inducible NO synthase (iNOS). NO in skeletal muscle is partly generated by nNOS, and nNOS deficiency can contribute to muscular dystrophic diseases. However, we and others discovered an alternative nitrate/nitrite reductive pathway for NO generation: nitrate to nitrite to NO. We hypothesized that nitrate supplementation would increase nitrate accumulation in skeletal muscle and promote a nitrate/nitrite reductive pathway for NO production to compensate for the loss of nNOS in skeletal muscle.Methods:Wild-type (WT) and genetic nNOS knockout (nNOS−/−) mice were fed normal chow (386.9 nmol/g nitrate) and subjected to three treatments: high-nitrate water (1 g/L sodium nitrate for 7 days), low-nitrate diet (46.8 nmol/g nitrate for 7 days), and low-nitrate diet followed by high-nitrate water for 7 days each.Results:High-nitrate water supplementation exhibited a greater and more significant increase in nitrate levels in skeletal muscle and blood in nNOS−/− mice than in WT mice. A low-nitrate diet decreased blood nitrate and nitrite levels in both WT and nNOS−/− mice. WT and nNOS−/− mice, treated with low-nitrate diet, followed by high-nitrate water supplementation, showed a significant increase in nitrate levels in skeletal muscle and blood, analogous to the increases observed in nNOS−/− mice supplemented with high-nitrate water. In skeletal muscle of nNOS−/− mice on high-nitrate water supplementation, on low-nitrate diet, and in low–high nitrate treatment, the loss of nNOS resulted in a corresponding increase in the expression of nitrate/nitrite reductive pathway-associated nitrate transporters [sialin and chloride channel 1 (CLC1)] and nitrate/nitrite reductase [xanthine oxidoreductase (XOR)] but did not show a compensatory increase in iNOS or eNOS protein and eNOS activation activity [p-eNOS (Ser1177)].Discussion:These findings suggest that a greater increase in nitrate levels in skeletal muscle of nNOS−/− mice on nitrate supplementation results from reductive processes to increase NO production with the loss of nNOS in skeletal muscle

Persistent hypertension up to one year postpartum among women with hypertensive disorders in pregnancy in a low-resource setting:A prospective cohort study

BACKGROUND: Hypertensive disorders in pregnancy (HDPs) are associated with lifelong cardiovascular disease risk. Persistent postpartum hypertension in HDPs could suggest progression to chronic hypertension. This phenomenon has not been well examined in low- and middle-income countries (LIMCs), and most previous follow-ups typically last for maximally six weeks postpartum. We assessed the prevalence of persistent hypertension up to one year in women with HDPs in a low resource setting and determined associated risk factors. METHODOLOGY: A prospective cohort study of women conducted at eight tertiary health care facilities in seven states of Nigeria. Four hundred and ten women with any HDP were enrolled within 24 hours of delivery and followed up at intervals until one year postpartum. Descriptive statistics were performed to express the participants’ characteristics. Univariable and multivariable logistic regressions were conducted to identify associated risk factors. RESULTS: Of the 410 women enrolled, 278 were followed up to one year after delivery (follow-up rate 68%). Among women diagnosed with gestational hypertension and pre-eclampsia/eclampsia, 22.3% (95% CI; 8.3–36.3) and 62.1% (95% CI; 52.5–71.9), respectively, had persistent hypertension at six months and this remained similar at one year 22.3% (95% CI; 5.6–54.4) and 61.2% (95% CI; 40.6–77.8). Maternal age and body mass index were significant risk factors for persistent hypertension at one year [aORs = 1.07/year (95% CI; 1.02–1.13) and 1.06/kg/m(2) (95% CI; 1.01–1.10)], respectively. CONCLUSION: This study showed a substantial prevalence of persistent hypertension beyond puerperium. Health systems in LMICs need to be organized to anticipate and maintain postpartum monitoring until blood pressure is normalized, or women referred or discharged to family physicians as appropriate. In particular, attention should be given to women who are obese, and or of higher maternal age

Metabolic syndrome following hypertensive disorders in pregnancy in a low-resource setting:A cohort study

Objectives: Hypertensive disorders in pregnancy (HDPs) are associated with risk of future metabolic syndrome. Despite the huge burden of HDPs in sub-Saharan Africa, this association has not been adequately studied in this population. Study design: This was a prospective cohort study on pregnant women recruited between August 2017 - April 2018 and followed up to one year after their deliveries and evaluated for presence of metabolic syndrome at delivery, nine weeks, six months and one year. Main outcome measures: Prevalence of metabolic syndrome Results: A total of 488 pregnant women were included: 410 and 78 with HDPs and normotensive, respectively. None of the normotensive had metabolic syndrome until one year (1.7% = 1 out of 59 observations), while among those with HDPs were 17.4% (71 of 407), 8.7% (23 of 263), 4.7% (11 of 232) and 6.1% (17 of 278), at delivery, nine weeks, six months and one year postpartum, respectively. High BMI and blood pressure were the drivers of metabolic syndrome in this population. The incidence rate in HDPs versus normotensive at one year were, respectively, 57.5/1000 persons’ year (95%CI; 35.8 – 92.6) and 16.9/1000 persons’ years (95%CI; 2.4-118.3), with incidence rate ratio of 3.4/1000 person's years. Only parity significantly predicted the presence of metabolic syndrome at one year [(aOR= 3.26/delivery (95%CI; 1.21-8.79)]. Conclusion: HDPs were associated with a higher incidence of metabolic syndrome up to one year postpartum. Women with HDPs should be routinely screened for metabolic syndrome within the first year postpartum to reduce cardiometabolic risks.</p

Blindness following ventriculoperitoneal shunt block in a child with spinal dysraphism: Case report

A six-year-old boy presented with a week history of increasing headache, visual loss and convulsions. He had repair of myelomeningocele early in life and later had insertion of a ventriculoperitoneal shunt for hydrocephalus after the repair. He was treated for meningitis at the referring hospital without improvement. Computed tomography scan of the brain showed ventricular enlargement. The shunt was found to be broken and blocked and was revised. This was followed by rapid improvement but vision was never regained. Shunt malfunction in patients with spinal dysraphism can lead to visual loss but the features may mimic those of meningitis, and delayed referral and treatment. Early shunt revision should prevent this complication. East African Medical Journal Vol.82(2) 2005: 107-10

The effect of hyoscine butyl bromide in shortening the duration of first stage of labor: A single-blind randomized control study

Background: Active management of labor reduces the number of prolonged labor and the duration of labor without having any adverse effects on the mother and the fetus. Intervention with drugs is among the options used for active management of labor. This includes use of analgesics, oxytocics, prostaglandins derivatives, and smooth muscle relaxants. The objectives of the study were to determine whether hyoscine N butyl bromide (HNBB) shortens the first stage of labor in term pregnancies, to compare the mean duration of labor between primigravidae and multigravidae in HBB group, to compare the maternal and fetal outcome between HBB and control group, and also to determine the side effects of HBB in parturients. Materials and Methods: The study was a single-blind randomized control study carried out in Usmanu Danfodiyo University Teaching Hospital (UDUTH) over 4-month period. A total of 204 pregnant women at term in spontaneous labor who presented in active phase of labor at UDUTH and have met the inclusion criteria were recruited and randomized into 102 women as case group and 102 women as control. The women in the case group received 40 mg (2 mls) of HBB, while those in the control group received 2 mls of normal saline. Data entry and analysis was done with IBM SPSS version 20. The duration and outcome was monitored. Results: The mean duration of labor in the first stage among the case group was 5:44 ± 2:11, while it was 6:52 ± 2:11 among the control group representing a decrease of 16.5%. This was statistically significant (P < 0.05). There was no difference in the duration of the second and third stages of labor among the two groups. There was no difference in the maternal and neonatal outcome among the two groups. Vomiting was the only maternal side effect that was statistically significant among the HBB group. Conclusion: HBB reduced the duration of first stage of labor in both primigravid and multigravid women without adverse maternal and neonatal complications. It is recommended that HBB to be given to women in active phase of labor to reduce the incidence of prolonged labor

Destructive Operative Vaginal Delivery in a Tertiary Health Institution in Northwestern Nigeria : A Ten Year Review

A. BACKGROUND: Destructive operations are a group of obstetric procedures that are performed via the vaginal route by reducing the size of the head, shoulder girdle, or trunk of the dead foetus to allow vaginal deliveryto avert caesarean section and its complications. B. AIMS AND OBJECTIVES:TO determining the incidence rate, indications, complications and outcome of destructive operations in UDUTH, Sokoto. C. MATERIALS AND METHODS: This was a 10 year retrospective study of destructive operations performed at UDUTH. Sokoto,nbsp from 1st January 2005 to 31st December 2014. Information was extracted from patientrsquos case files retrieved from the medical records department. D.RESULTS: There were 28,422 deliveries during the period under review. The incidence of destructive operation was 0.31% and the mean age of the patients was 20 plusmn 4.7 years. Majoritynbsp are in their 2nd decades of life and they presented mainly as emergencies. The mean gestational age at presentation was 38.55 plusmn 1.401 weeks and the procedures were successful in all the cases. The most common procedure was craniotomy in 76/84 (90.50%) and the main indication was prolonged and obstructed labour in 76/84 (90.5%) of cases. The most frequent complication encountered was anaemia in 52/84 (61.9%) of the patients and there were four cases of maternal deaths (4.76%). E.CONCLUSION: Destructive operations still have a role in the management of obstructed labour particularly if the foetus is dead. However, the trend is on a decrease due to risk of complicationsnbsp that may lead to litigation
