Trolley Monitoring System
The project involves building a software system to send mobile alerts to users when the Florida Tech Trolley is nearing their signed-up location. The users will be able to sign up for alerts and notifications for a particular trolley stop and for different time intervals. When the trolley is nearing the location, the user will receive an alert with the estimated time of arrival, so they can be at the stop on time
An evaluation of intra-operative and post-operative blood loss in total knee arthroplasty at the National Orthopaedic Hospital, Lagos
Background: Total knee replacement is a rewarding and reliable procedure, producing a lasting relief to severe knee pains. However, significant blood loss usually in the post-operative period may be a challenge, necessitating prompt restoration of circulating blood volume to minimize morbidity and mortality. The aim of this study was to evaluate blood loss after total knee replacementPatients and Methods: A prospective study of blood loss after Total Knee Arthroplasty in 53 patients in the National Orthopaedic Hospital, Lagos. Consecutive patients with established indications, presenting for total knee arthroplasty were recruited into the study after obtaining their consent.Results: The mean intra-operative blood loss was 342.4 mls, with a range of 50 - 1500 mls. The mean post-operative blood loss and total blood loss were 603.6 mls and 940.3 mls respectively, showing a strong positive correlation (r = 0.884, p < 0.01). The average pre-operative and post-operative haemoglobin concentration were 12.5 ± 1.2 g/dl and 9.8 ± 0.9 g/dl, respectively. The mean haemoglobin loss was 2.6 ± 1.2 g/dl (r = 0.46, p < 0.001).Conclusion: Post-operative blood loss as measured by suction drainage, is a good predictor of total blood loss, showing a strong and positive correlation.Keywords: Total Knee Arthroplasty, Blood loss, Tourniquet, Surgical time
The relation of the true conjugate to maternal height and obstetric performance in Ghanaians
The true conjugate was determined intraoperatively with a caliper in 114 Ghanaian women and was correlated with their height, obstetric performance and fetal dimensions. Those patients undergoing cesarean section for cephalopelvic disproportion (Group Ia) were found to have a significantly shorter mean true conjugate (9.54 cm +/- 0.63 S.D.) and mean body height (152.68 cm +/- 5.46 S.D.) and a smaller true conjugate -- fetal biparietal diameter difference (10.93 mm) than those who had no cephalopelvic disproportion (Group Ib) and whose mean measurements were 10.61 cm +/- 0.81 S.D., 157.20 cm +/- 5.69 S.D. and 21.50 mm, respectively (P = 0.0001). Recommendations for appropriate referral of rural clinic patients and for selection of patients for repeat cesarean sections are based on the above findings.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28033/1/0000472.pd

Menarcheal age in Ghanaian school girls
In a cross-sectional retrospective study of 2087 Ghanaian school girls in various educational institutions in the Kumasi district, Ashanti region, Ghana, the mean menarcheal age was found to be 13.98 +/- 1.42 years. Differences in the menarcheal age of the girls was found to be significantly correlated to social class, parents ethnic origin, educational institution and home living area (P = 0.0001). The duration of the menarche and the interval between the menarche and the second period was found to be influenced by the age at menarche (P < 0.01). Decline in menarcheal age in concurrence with world trends was observed. Further studies are necessary to identify the inherent and specific factors in the Ghanaian population which relate to and influence the age of menarche.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27765/1/0000159.pd
Parental Height Differences Predict the Need for an Emergency Caesarean Section
More than 30% of all pregnancies in the UK require some form of assistance at delivery, with one of the more severe forms of assistance being an emergency Caesarean section (ECS). Previously it has been shown that the likelihood of a delivery via ECS is positively associated with the birth weight and size of the newborn and negatively with maternal height. Paternal height affects skeletal growth and mass of the fetus, and thus might also affect pregnancy outcomes. We hypothesized that the effect of newborn birth weight on the risk of ECS would decrease with increasing maternal height. Similarly, we predicted that there would be an increase in ECS risk as a function of paternal height, but that this effect would be relative to maternal height (i.e., parental height differences). We used data from the Millennium Cohort Study: a large-scale survey (N = 18,819 births) with data on babies born and their parents from the United Kingdom surveyed 9 to 12-months after birth. We found that in primiparous women, both maternal height and parental height differences interacted with birth weight and predicted the likelihood of an ECS. When carrying a heavy newborn, the risk of ECS was more than doubled for short women (46.3%) compared to tall women (21.7%), in agreement with earlier findings. For women of average height carrying a heavy newborn while having a relatively short compared to tall partner reduced the risk by 6.7%. In conclusion, the size of the baby, the height of the mother and parental height differences affect the likelihood of an ECS in primiparous women
Incidence of uterine post abortion infection at Hospital de Clínicas de Porto Alegre. Is prophylactic antibiotic necessary?
Objetivo: Identificar a incidência de infecção pélvica após aborto espontâneo submetido a esvaziamento uterino num hospital terciário do sul do Brasil e comparar com a literatura internacional. Métodos: Os prontuários eletrônicos do Hospital de Clínicas de Porto Alegre de todas as pacientes que foram submetidas ao esvaziamento uterino por abortamento entre agosto de 2008 e Janeiro de 2012 foram revisados. Foram incluídas no estudo todas as pacientes submetidas à curetagem uterina por abortamento e que tiveram consultas ambulatoriais de revisão após o procedimento. Os dados demográficos e laboratoriais da população estudada, number needed for treatment (NNT) e o number needed to harm (NNH) foram calculados. Resultados: Dos 857 prontuários eletrônicos revistos, 377 pacientes foram submetidas ao esvaziamento uterino por abortamento; 55 casos foram perdidos no seguimento, restando 322 casos que foram classificados como aborto não infectado na admissão. A maioria da população era da raça branca (79%); a prevalência de HIV e VDRL positivos foi de 0,3 e 2%, respectivamente. No seguimento desses 322 casos, num período mínimo de 7 dias, verificou-se que a incidência de infecção pós-procedimento foi de 1,8% (IC95%0,8 a 4). O NNT e o NNH calculado para 42 meses foi de 63 e 39, respectivamente. Conclusão: A incidência de infecção pós-aborto entre agosto de 2008 a janeiro de 2012 foi de 1,8% (0,8 a 4).Objective: To identify the incidence of infection post-uterine evacuation for miscarriage at a tertiary teaching hospital in southern Brazil. Methods: Electronic records of all patients admitted for uterine evacuation for miscarriage between August 2008 and January 2012 were revised. All patients submitted to uterine curettage for miscarriage and had outpatient follow-up were included. Demographic, laboratorial data of the sampled population, the number needed to treat (NNT) and number needed to harm (NNH) were calculated. Results: From 857 reviewed electronic records, 377 underwent uterine evacuation for miscarriage. 55 cases were lost to follow-up, remaining 322 cases classified as non-infected miscarriage at admission. The majority of the population was white (79%); prevalence of positive HIV and VDRL was 0.3 and 2%, respectively. From 322 cases, within a week of follow-up, the incidence of post-miscarriage infection was 1.8% (95%CI 0.8 to 4). In a period of 42 months, the NNT and NNH were 63 and 39, respectively. Conclusion: The incidence of infection after miscarriage between August 2008 and January 2012 was 1.8% (0.8 to 4)
Association between adolescent idiopathic scoliosis prevalence and age at menarche in different geographic latitudes
BACKGROUND: Age at menarche is considered a reliable prognostic factor for idiopathic scoliosis and varies in different geographic latitudes. Adolescent idiopathic scoliosis prevalence has also been reported to be different in various latitudes and demonstrates higher values in northern countries. A study on epidemiological reports from the literature was conducted to investigate a possible association between prevalence of adolescent idiopathic scoliosis and age at menarche among normal girls in various geographic latitudes. An attempt is also made to implicate a possible role of melatonin in the above association. MATERIAL-METHODS: 20 peer-reviewed published papers reporting adolescent idiopathic scoliosis prevalence and 33 peer-reviewed papers reporting age at menarche in normal girls from most geographic areas of the northern hemisphere were retrieved from the literature. The geographic latitude of each centre where a particular study was originated was documented. The statistical analysis included regression of the adolescent idiopathic scoliosis prevalence and age at menarche by latitude. RESULTS: The regression of prevalence of adolescent idiopathic scoliosis and age at menarche by latitude is statistically significant (p < 0.001) and are following a parallel declining course of their regression curves, especially in latitudes northern than 25 degrees. CONCLUSION: Late age at menarche is parallel with higher prevalence of adolescent idiopathic scoliosis. Pubarche appears later in girls that live in northern latitudes and thus prolongs the period of spine vulnerability while other pre-existing or aetiological factors are contributing to the development of adolescent idiopathic scoliosis. A possible role of geography in the pathogenesis of idiopathic scoliosis is discussed, as it appears that latitude which differentiates the sunlight influences melatonin secretion and modifies age at menarche, which is associated to the prevalence of idiopathic scoliosis
Sexual dimorphism in the human pelvis: Testing a new hypothesis
Sexual dimorphism in the human pelvis is inferentially related to parturition. Investigators disagree about the identification and obstetric significance of pelvic dimorphism. Benefiting from a large sample of complete skeletons from the Coimbra Identified Skeletal Collection, we show that the dimensions of the true pelvis (birth canal) that are most sexually dimorphic (that is, the dimensions of females are greater than males) are those which are related to biparietal deformation, which often leads to the death of the human neonate. These dimensions are: the anteroposterior diameter of the inlet (index of dimorphism=108.41), the transverse diameter of the bispinous midplane (index of dimorphism=117.13) and the transverse diameter of the outlet (index of dimorphism=112.3). Therefore, sexual dimorphism in the human pelvis is a reflection of differential selection on the two sexes. These results may stimulate further studies with a fresh approach regarding the fossil and comparative evidence for when and how the modern pattern of birth has evolved.http://www.sciencedirect.com/science/article/B7GW4-4GG8W5B-1/1/d5a210bbbf111453aceef7b3895130c
