Risk factors for some tropical diseases in an African country.

BACKGROUND: Often, non-clinical risk factors could affect the predisposition of an individual to diseases. Understanding these factors and their impacts helps in disease prevention and control. This study identified risk factors for malaria, yellow fever, typhoid, chickenpox, measles, hepatitis B, and urinary tract infection in a population in an African country. METHODS: Our study was an observational, correlational, and quantitative one that explored relationships among risk variables and disease prevalence - without modifying or controlling the variables. Data for this study was obtained through random sampling of a population of patients and physicians in the eastern/southern, western, and northern parts of Nigeria in 2015-2016. A total of 2199 patient consultation forms were returned by 102 (out of 125) physicians, and considered useful for analysis. Demographic data of patients, physicians, and diagnosis outcomes were analysed descriptively through frequency distributions, aggregate analysis, and graphs. The influence of risk factors on the disease manifestations (diagnosis outcomes) was determined using regression analysis. RESULTS: Our results show that living in a tropical climate is by far a major risk factor associated with tropical diseases (malaria: t = 19.9, typhoid: t = - 3.2, chickenpox: t = - 6.5 and typhoid: t = 12.7). The risk for contracting infections is relative to specific diseases; for example, contact with chickenpox infected person poses a high risk of contracting the virus (t = 41.8), while poor personal hygiene predisposes people to high risk of urinary tract infection (t = 23.6). On the other hand, urbanization and homelessness pose very low risks of disposing the individual to the diseases under consideration, while low fluid intake, lack of voiding, and wearing non-cotton underwear predispose individuals to few diseases. CONCLUSION: The risk factors identified in our study exert differential and discriminating influences in the causation, predisposition, and transmission of these disease studied. It is recommended that significant effort be devoted by governments in the tropics to the mitigation of these modifiable risk factors. The most important strategy to mitigate the occurrence of these risk factors will be improving the living conditions of people and the provision of social protection measures to reduce the occurrence and burden of these diseases.

An audit of the Day-of-Surgery Cancellation of Scheduled Surgical Procedures in Sagamu, Nigeria

Background: Timely performance of scheduled surgical procedures may be an indirect method of assessing the quality of surgical services in a hospital.Objective: This study aimed to determine the rate and the reasons for day-of-surgery cancellation of elective surgical procedures.Methods: A prospective study was conducted at the Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria to audit the type of surgery and the reasons for the cancellation of procedure among patients scheduled for elective surgical procedures.Results: A total of 1,324 patients were scheduled for elective surgeries during the period of audit and 268 (20.2%) were cancelled on the day of surgery. One hundred and seventy-four of the 268 (65.0%) cancellations were avoidable while 94 (35.0%) cancellations were unavoidable. The reasons for the cancellation of surgeries included patient-related factors (35.0%), unfavourable pre-operative clinical evaluation (31.0%), facility-based factors (28.0%) and surgeon-related factors (6.7%).Conclusion: The day-of-surgery cancellation rate was 20.2%, and the three leading causes of cancellation of elective surgeries in Sagamu included patient-related factors, unfavourable pre-operative clinical evaluation and inadequacies of hospital resources

Abdominal Masses in Children: A 10-Year Review

Background: Some childhood diseases present with abdominal masses alone or with other constitutional symptoms. The knowledge of the common causes of abdominal masses in children can assist in developing a protocol of management by clinicians.Objective: To describe the aetiology and presentation of abdominal masses in children.Methods: The hospital records of all cases of intra-abdominal masses in children managed between May 1998 and April 2008 were retrieved for analysis. Socio-demographic and clinical data were obtained and analysed using simple descriptive statistics.Results: A total of 93 children were included while those without clinical, radiological and intra-operative evidence of intra-abdominal masses were excluded from the study. There were 49 males (52.7%) and 44 (47.3%) females with male-to-female ratio of 1.1:1. The children were aged 1 day to 14 years; 15 (16.1%) were aged <3 years while 23 (24.7%), 27 (29%) and 14 (15.1%) each were aged 3-6 years, >6-9 years, >9-12 years and >12-14 years. The most common cause of abdominal masses was appendiceal mass/abscess in 29%, followed by hydronephrosis in 22.6% and nephroblastoma in 16.11%. The most common symptoms included abdominal pain (86.0%), fever (46.2%), vomiting (40.9%) and abdominal distension (32.2%). The mortality rate was 13%.Conclusion: Non-malignant conditions were mostly responsible for abdominal masses in children while abdominal pain, fever and vomiting were the leading presentations of abdominal masses in children

Experience with Lichtenstein Hernioplasty in Sagamu

Background: Newer methods have evolved to address the major drawback of the traditional methods of hernia repair. These emphasize the use of prosthetic materials to strengthen the posterior wall of the inguinal canal without tension. Although Lichtenstein hernioplasty, like other newer methods, is associated with low recurrence rates, it is not commonly used in our clinical setting.Objective: To review the outcome of Lichtenstein hernioplasty using polypropylene mesh in a resource-poor setting.Methods: The hospital records of patients who had Lichtenstein hernioplasty between the year 2004 and 2013 in a six-bed private surgical clinic and who were followed up over a two- to ten-year period, were studied. Demographic data, clinical features, operative findings and outcome measures like post-operative complications and recurrence rates, were recorded.Results: There were 62 patients (with 69 hernias) of which 2 were females with the age range of 12-84years. 50 hernias (72.5%) were of the inguinoscrotal type, 39 patients (63.0%) had right inguinal hernias, 5 (7.2%) hernias were obstructed and 8 (11.2%) hernias were recurrent. Six (9.7%) had emergency surgery, 46 (74.2%) had surgery under local infiltrations and 15 (24.2%) had spinal anaesthesia. Scrotal oedema (4.3%), haematoma (1.4%), and hydrocoele (1.4%) were the early complications recorded. One recurrence of hernia occurred in a patient who had repair of twice recurrent hernia. The mean duration of follow-up in years was 5 (S.D 2.5) years.Conclusion: Lichtenstein repair of inguinal hernia was a safe and effective procedure in the private clinical setting

Pregnancy, obstetric and neonatal outcome after assisted reproduction in Nigerians.

PURPOSE: To evaluate the pregnancy, obstetric and neonatal outcome after assisted reproduction in Nigerians. METHODS: Case control study of all confirmed pregnancies following assisted reproduction managed at the Havana Specialist Hospital (HSH), Lagos over a 7 year period. RESULTS: Adverse obstetric and neonatal outcome occurred in 30.8% of pregnancy following assisted reproduction compared to 12.6% in spontaneously conceived pregnancy (p = 0.0003). Multiple pregnancy (<0.001), preterm delivery (p < 0.000), placenta praevia (0.00002), antenatal admission (0.02), early pregnancy bleeding (0.04), miscarriage (0.001) and caesarean delivery (<0.001) were significantly commoner in the assisted reproduction group. After adjustment for confounding variables, preterm delivery (OR: 5.95), miscarriage (OR: 5.84), multiple pregnancy (OR: 4.58), placenta praevia (OR: 4.13), caesarean delivery (OR: 3.57), early pregnancy bleeding (OR: 2.18) and antenatal admission (OR: 2.01) retained their significance. CONCLUSION: This study has provided the first evidence from our part of the world showing that assisted pregnancy is associated with poorer obstetric outcome when compared with spontaneously conceived pregnancy.

The effects of birth interval on the birthweights of consecutive, same-sex term siblings.

OBJECTIVE: To investigate the effect of birth interval on the relationship between the birthweights of successive siblings. METHODS: The records of women who had delivered two consecutive, same-sex, live, singletons babies (1983 through 1997) in a private hospital were analysed. The intervals between the birth dates of the siblings were calculated. The first of the siblings was coded Set A and the second, Set B. The ratios of the birthweights (Set B/Set A) were calculated. Comparison of findings was made between various ranges of birth interval. RESULTS: The birth interval band 24-29 months was associated with the highest mean birthweight for Set B babies and the highest birthweight ratio (p=0.016). Set A babies weighing less than 3000 g were most likely to be outweighed by their Set B siblings (p=0.000001). CONCLUSION: Birth intervals of 24 to 29 months and small size of Set A babies were associated with most significant advantages in birthweight for Set B siblings.

Uterine incision closure at caesarean section: a randomised comparative study of intraperitoneal closure and closure after temporary exteriorisation.

BACKGROUND: The safety of the technique of uterine exteriorization at caesarean section though popular among obstetricians, remains controversial. OBJECTIVE: To evaluate the influence of exteriorization of uterus during uterine repair on caesarean morbidity. METHODS: A randomized comparative study of 136 women undergoing primary caesarean delivery at Havana Specialist Hospital Lagos Nigeria. Data on operation time, estimated blood loss, postoperative morbidities were collected and analysed with comparison between the two groups using chi square, Fischer's exact test and t-test as appropriate. RESULTS: The mean operative time, estimated blood loss, transfusion rate and postoperative anemia rate were significantly less in the exteriorized group than the intraperitoneal group (p = 0.000, 0.009,0.048 0.038 and 0.028 respectively), but not in other outcome measures. CONCLUSION: With shorter operative time, less blood loss and similar morbidity profile exteriorization of uterus during caesarean section seems to be preferred except where it is not possible because of adhesions and surgeons inexperience.

Emergency peripartum hysterectomy in a Nigerian hospital: a 20-year review.

Postpartum haemorrhage is a major cause of maternal morbidity and mortality and occasionally severe enough to warrant hysterectomy to prevent maternal death. Hysterectomy often is fraught with danger and regular audit is necessary to assist in the reduction of these dangers. A 20-year audit of all emergency peripartum hysterectomies, performed at Havana Specialist hospital Lagos, Nigeria, is reported. Of the 6599 deliveries and peripartum referrals seen during the period, 22 had an emergency hysterectomy as a result of severe postpartum haemorrhage (0.33%). The aetiological factors associated with the postpartum haemorrhage included uterine atony (45.5%), placenta praevia (27.3%), pathologically adherent placenta (18.2%) and ruptured uterus (9.1%). The majority of the procedures were subtotal hysterectomy (81.8%) and the mean operative time was significantly shorter than for total hysterectomy (P<0.05). The postoperative complications included postoperative anaemia (28.6%), febrile morbidity (36.9%), wound infection (19.0%) and urinary tract infection (9.5%), together with three maternal deaths. In conclusion, emergency peripartum hysterectomy, although life-saving, is associated with severe morbidity and mortality and subtotal hysterectomy is usually the operation of choice.

Vaginal misoprostol induction of labour: a Nigerian hospital experience.

We reviewed our experience with vaginal misoprostol induction of labour in 339 consecutive women with a live fetus and intact fetal membrane using 100 mcg 12-hourly until labour was established. The labours were monitored using the WHO partograph protocol. Two hundred and sixty-five women had a successful induction while 74 had an emergency caesarean section because of cephalopelvic disproportion (63.5%), fetal distress (14.9%), prolonged labour (12.2%), antepartum haemorrhage (6.8%) and other indications (2.8%). The induction delivery interval among the women who had successful induction ranged from 3 hours 42 minutes to 26 hours 15 minutes with a mean of 9 hours 23 minutes (SD 2 hours 41 minutes). Most (73.6%) of these patients delivered within 12 hours of starting induction, the majority (95.3%) requiring only 100 mcg to go into established labour. Complications recorded in this series include fetal distress in 32 (9.4%), postpartum haemorrhage in 23 (6.8%), hyperstimulation in six (1.8%), uterine rupture in one (0.3%), birth asphyxia in eight (2.5%), admission in neonatal intensive care ward in five (1.5%), neonatal death in one (0.3%) and maternal death in one (0.3%) patient. In conclusion, misoprostol was found not only to be efficacious but relatively safe in comparison to other methods of induction in use in our hospital.

Prevalence and pattern of domestic violence against pregnant Nigerian women.

Five hundred and twenty-two pregnant Nigerians attending the antenatal clinic in two private hospitals in Lagos between January and June 2003 were interviewed using a structured questionnaire about their experiences of domestic violence. One hundred and four women declined to participate; a response rate of 80.1% was obtained. Analysis of the completed questionnaire by 418 respondents showed that 197 (47.1%) women reported a history of abuse. Of the 197 women who reported abuse, 23 (11.7%) experienced abuse for the first time during the current pregnancy, 97 (49.2%) experienced abuse prior to and during the current pregnancy and in the remaining 77 (39.1%) abuse predate the current pregnancy. A total of 120 (28.7%) women experienced some form of abuse during current pregnancy. Although all social and ethnic groups were involved, no association could be established between prevalence and pattern of abuse and sociodemographic characteristics. Verbal abuse was the most common type of abuse reported (52.3%), followed by economic deprivation (30%), physical abuse (25%), threat of violence (10.8%) and forced sex in 14.2%. The perpetrators of the abuse were husband and boyfriend (78.7%), in-laws (31.5%) and other relations (6.1%). The majority of abused women (99.0%) were not ready to report the abuse to the police. In conclusion, domestic violence is common in our environment and health-care providers should be alert to the clues in order to protect the women from further abuse.

Donor insemination in Lagos.

The results of AID in a population with a high incidence of female factors is reported. Thirty-one patients started AID on 35 occasions resulting in 25 pregnancies and a cumulative conception rate of 71% at 8 months. Eleven patients with female factors present became pregnant. Some problems of AID practice in Lagos are highlighted.
