RESUMEN

INTRODUCTION AND IMPORTANCE: Uterine leiomyomas, or fibroids, are benign mesenchymal tumors, which represent the most common tumors of the female genital tract. Their occurrence in pediatric and adolescent populations is uncommon, and relatively few cases have been documented in the literature, particularly in lower-resourced settings. This case highlights the importance of recognizing that although uncommon, fibroids can occur in much younger populations. Also highlights the need for healthcare practitioners in resource-limited environments to be vigilant in considering leiomyoma in differential diagnoses, even in younger patients, and to adapt their treatment approach given the constraints of local healthcare systems. CASE PRESENTATION: Here we present an uncommon case of uterine leiomyoma in a 16-year-old female from Northern Tanzania. She presented with lower abdominal pain associated with abdominal distension, prolonged menses, headache, and anemia. Transvaginal US and pelvic MRI were performed and revealed an enlarged uterus with a heterogeneous mass in the posterolateral uterine wall. Myomectomy was performed, and post-operative recovery was uneventful. The final histopathological report confirmed the diagnosis of intramural uterine leiomyoma. CLINICAL DISCUSSION: In this report, we discuss the rarity of this condition, the literature surrounding similar reports, and the many challenges that arise in the management of leiomyoma in a young adolescent population. CONCLUSION: Uterine leiomyomas should be considered as a differential diagnosis in pediatric and adolescent females presenting with a pelvic mass and abdominal pain. Though there are no specific guidelines for treatment, management of leiomyomas in this age group, should be conservative and based on symptom severity with the goal of preserving fertility.This case underscores the need for more research and awareness of uterine leiomyomas in adolescents to improve understanding and management of this rare condition in this age group, particularly in regions like Northern Tanzania where access to healthcare may be limited.

RESUMEN

INTRODUCTION AND IMPORTANCE: Mucinous cystadenoma is a benign cystic ovarian tumor arising from the surface epithelium of the ovary that usually presents with vague, unspecified abdominal symptoms. If not detected early, this tumor has the potential to grow to a substantial size and can present with huge abdominal distention leading to various compression symptoms. The reported incidence of giant ovarian cystadenoma in postmenopausal women is relatively unknown due to the widespread use of ultrasound and other radiological imaging modalities. CASE PRESENTATION: Here, we present a rare case of giant borderline mucinous cystadenoma in a 67-year-old female 10 years postmenopausal from Northern Tanzania with multiple comorbidities including hypertension and type 2 diabetes mellitus. She presented with abdominal distention which was of gradual onset for 1 year. Abdominal CT scan with contrast revealed a huge septated cystic mass occupying the entirety of the abdominal and pelvic cavities causing a mass effect on adjacent intra-abdominal structures. An intact 23-kg left ovarian cyst was removed, and a total abdominal hysterectomy (TAH) along with bilateral salpingo-oophorectomy (BSO) was performed. Post-operative recovery was excellent and the patient was discharged. The final histopathological report showed a borderline ovarian mucinous cystadenoma and the patient was managed conservatively after surgery. CLINICAL DISCUSSION: In this case report, we discuss the condition's rarity especially in postmenopausal women, related reports in the literature, and the numerous difficulties clinicians face when encountering a patient with borderline mucinous cystadenoma. The rarity of borderline mucinous cystadenomas in postmenopausal women makes these cases clinically unusual, challenging diagnostic and therapeutic expectations. CONCLUSION: This case report highlights the importance of thoroughly evaluating women with vague abdominal symptoms. While this condition is rare in postmenopausal women, its massive form can be dangerous if not diagnosed and managed promptly, with the potential to progress to malignancy. Greater awareness of this condition could lead to earlier detection and reporting of more cases.

RESUMEN

INTRODUCTION AND IMPORTANCE: Cervical carcinosarcomas (CCS) are uncommon aggressive gynecological malignancies that typically occur in postmenopausal females. Data on CCS, incidence, clinical presentation, magnitude and management strategies remain scarce especially in Sub-Saharan countries like Tanzania. In this report, we report the rarity of this particular condition in premenopausal woman, the literature surrounding similar reports, and the many challenges that arise in the management of CCS. CASE PRESENTATION: We present a redudancy case of a 35-year-old female from Northern Tanzania who presented with vaginal bleeding, foul smelling discharge, and severe abdominal pain intermittently for a year. The Speculum exam revealed a fungating mass on the cervix, and CT confirmed the irregular mass centered in the uterine cervix expanding in the fornices infiltrating the uterine neck. A cervical biopsy revealed carcinosarcoma of the cervix stage IIA. Due to the patient's instability, she was admitted and started on chemotherapy and later on recommended for radiation without surgical intervention. CLINICAL DISCUSSION: In this case report, we discuss the condition's rarity and multiple barriers we encountered during management of this complicated patient with CCS. Choosing an optimal treatment approach was challenging due to the lack of guidelines and available literature as well as the patient's instability. CONCLUSION: his case is notable due to the rarity of this cervical neoplasm especially in premenopausal women and the challenging management of the condition due to a notable lack of treatment recommendations.

RESUMEN

INTRODUCTION AND IMPORTANCE: A cervical stump fibroid is a rare type of leiomyoma (fibroid) that occurs in the remaining cervical tissue following a subtotal hysterectomy. In this procedure the uterus is removed but the cervix is left intact. Cervical stump fibroids are quite rare, with studies indicating that they occur in less than 1 % of women who have undergone subtotal hysterectomy. The present report describes a rare case of uterine fibroid arising from the cervical stump 7 years after subtotal hysterectomy. The aim is to strengthen the existing literature and aid clinicians in the management of similar cases. CASE PRESENTATION: A 45-year-old female presented with a history of abdominal distension, abdominal pain, and bilateral lower limb swelling for 1 year. An abdominal Computed Tomography (CT) scan with contrast and Magnetic Resonance Imaging (MRI) revealed a large multilobulated mass in the pelvis measuring 14.3 × 7.4 × 21.1 cm. The mass displaces and compresses the urinary bladder anteriorly and the rectosigmoid colon posteriorly. Additionally, there is compression of the distal ureters bilaterally with resultant bilateral hydroureteronephrosis. The patient underwent explorative laparotomy and post-operative recovery was uneventful. The final histopathological report showed the diagnosis of uterine fibroid. CLINICAL DISCUSSION: In this case report, we discuss the condition's rarity, related reports in the literature, and the numerous difficulties clinicians face when encountering a patient with cervical leiomyomas. CONCLUSION: This case highlights the importance of long-term follow-up for patients post-supracervical hysterectomy, adds to the existing literature, and provides insight to healthcare providers in handling similar cases. Patients who are affected should receive appropriate counseling on postoperative care, recurrence after treatment, and the value of early and regular follow-up visits.

RESUMEN

BACKGROUND: Planned caesarean section (CS) is a risk factor for neonatal respiratory distress caused by a greater volume of airway liquid in the absence of uterine contractions.Performing a newly conceptualised knee-to-chest flexion (KCF) manoeuvre at birth, mimicking uterine contraction-induced flexion may aid in expelling excess lung liquid. OBJECTIVES: To test whether performing a KCF manoeuvre at birth is feasible in infants born after planned CS and to test whether KCF leads to visible expulsion of lung liquid. METHODS: Single-centre prospective interventional study in term infants born by planned CS at Leiden University Medical Centre, Netherlands. KCF was performed for a maximum of 45 s. Baseline characteristics were collected, primary outcome was ability to perform KCF and secondary outcome was any visible expulsion of fluid. RESULTS: In 39 infants (mean (SD) gestational age 38.0 (0.7) weeks, birth weight 3537 (440) g), KCF could be performed in 21/39 (54%), whereas 18/39 (46.2%) starting vigorous breathing before KCF could be performed. Notably, visible lung liquid expulsion occurred in 9/21 (43%) infants. KCF duration averaged 29 (18) s. In 13/21 (62 %), KCF was not performed as per standard operating procedure. No adverse events were reported. CONCLUSION: It is feasible to perform KCF at birth in a large proportion of term infants born by planned CS, with visible expulsion of liquid in a significant proportion of these infants. Training healthcare providers to perform a standardised KCF could increase feasibility and success. Further studies are needed to assess feasibility and effectiveness of KCF. TRIAL REGISTRATION NUMBER: NL74285.058.20.

RESUMEN

Key Clinical Message: Gestational macromastia is a rare disorder involving excessive breast tissue enlargement during pregnancy, potentially threatening the fetus and the mother. Our patient's previous pregnancies were more physiological, without any associated symptoms. Abstract: Moderate bilateral enlargement of the breasts is a normal finding during pregnancy and lactation. Occasionally, there is a continuity from this physiological hypertrophy to massive breast hyperplasia or gigantomastia, causing complications that threaten the wellbeing of the fetus and the mother or raising alarm for a malignant disease. We present a case of a 28-year-old G3P2L2 with a gestational age of 29 weeks complaining of massive bilateral breast enlargement for 6 months, accompanied by a threatened abortion. The masses began gradually after conception and increased gradually over time. Notably, the breasts had been unremarkable in her two previous pregnancies. The breast ultrasonography and mammography findings pointed to a benign neoplasm. Histopathology of the lesions reported bilateral ductal hyperplasia. Conservative management and close follow-up were initiated. A cesarean section was performed due to cord prolapse, and a 1.3 kg male baby was extracted. Unfortunately, the neonate succumbed after 3 days due to apnea of prematurity. The patients' breast size subsided considerably with time. Unusually large tumors can cause alarm for other pathologies, such as breast cancer. The radiological tests should reassure the attending practitioner, and the histological examination should confirm the diagnosis. An understanding of the typical and atypical clinico-pathologic characteristics of breast lesions occurring in pregnancy and lactation is essential for appropriate patient care.

RESUMEN

An ectopic pregnancy occurs when the fertilized egg is implanted and develops outside the endometrium, i.e. in the fallopian tubes, cervix, ovary, or abdomen. It commonly presents with a history of amenorrhoea, lower abdominal pain, and slight vaginal bleeding. The fallopian tube is the most typical location for ectopic pregnancy. Two percent of reported pregnancies are ectopic pregnancy. Ectopic pregnancy remains a public health threat for women in reproductive age, and a major cause of maternal mortalities in the first trimester. In East Africa, these reports are limited, despite a great need for documentation addressing key considerations for diagnosis and management of ectopic pregnancy in these resource limited settings. In this case study, we report on 26-years-old female Gravida 5 Para 4 Living 4, who reported history of amenorrhoea for 3 months complaining of slight per vagina bleeding and lower abdominal pain for 5 days more marked at left iliac region along with generalized weakness for 2 weeks. Her vitals were stable. Pelvic ultrasound revealed empty uterus and live fetus at the left adnexa corresponding to 14 weeks 6 days with minimal free fluid in the Douglas Cul-de-sac. The patient's final diagnosis was live extra-uterine pregnancy at 14 weeks 6 days that was managed by emergency laparotomy with salpingectomy. The patient recovered completely after surgery and was discharged in a stable condition. Ectopic pregnancy still remains one of the major causes of maternal morbidity and mortality. Early diagnosis and referral in hemodynamically state along with use of minimal access surgery or management can change the scenario of ectopic pregnancy in the developing world. Late attendance to first visit clinics is still a major concern in low resource limited settings as this could have been picked early and intervened. Key message: Management of broad ligament ectopic pregnancy in the second trimester is still challenging especially in low resource settings where the clients do not attend clinics and because of unavailability of ultrasound machines to diagnose it.

RESUMEN

BACKGROUND: In Ethiopia, both incidence and mortality of cervical cancer are relatively high. Screening services, which were implemented during the past few years, are currently being expanded. The World Health Organization recommends patients with a positive VIA (visual inspection with acetic acid) result should immediately receive treatment followed by rescreening after 1 year as precancerous lesions can reoccur or become residential despite treatment. MATERIALS AND METHODS: Screening logbooks dating between 2017 and 2020 were retrospectively reviewed in 14 health facilities of Addis Ababa and Oromia region. Data for 741 women with a VIA-positive result were extracted and those women were asked to participate in a questionnaire-based phone interview to gain insights about adherence to treatment and follow-up. Data were analyzed using descriptive methods and then fitted into 2 generalized linear models to test variables for an influence on adherence to follow up. RESULTS: Around 13 800 women had received a VIA screening, of which approximately 820 (5.9%) were VIA positive. While over 90% of women with a positive screen received treatment, only about half of the treated patients returned for a follow-up examination. After treatment, 31 women had a VIA-positive re-screen. We found that educational status, age over 40, no/incorrect follow-up appointment, health facility-related barriers, and use of reminders are important drivers of adherence to follow up. CONCLUSION: Our results revealed that adherence to treatment after VIA positive screening is relatively high whereas adherence to follow up recommendations still needs improvement. Reminders like appointment cards and phone calls can effectively reduce the loss of follow-up.

RESUMEN

The increasing prevalence of advanced maternal age (AMA) births necessitates the exploration of associated pregnancy outcomes within the healthcare-limited context of northern Tanzania to elucidate potential region-specific risks and implications. This study explored the influence of AMA on pregnancy outcomes in northern Tanzania, where healthcare resources and infrastructure are constrained in comparison to developed countries. This cross-sectional hospital-based study utilized maternally linked data from the Kilimanjaro Christian Medical Center (KCMC) Medical Registry and included 32,798 women who delivered single infants between 2004 and 2013. Multiple logistic regression models were used to determine adjusted odds ratios (aORs) and 95 % confidence intervals (CIs) for AMA-associated adverse pregnancy outcomes. A total of 16 % of mothers belonged to AMA with increased odds of undergoing a cesarean section (aOR: 1.32; 95%CI [1.24-1.41]; P < 0.001), gestational diabetes (aOR: 13.16; 95%CI [3.28-52.86]; P < 0.001) or pregestational diabetes (aOR: 3.15; 95%CI [1.87-5.31]; P < 0.000), and developing pre-eclampsia (aOR: 1.63; 95%CI [1.41-1.89]; P < 0.000). More women with AMA reported alcohol use during pregnancy and had preexisting conditions before conception than did younger women. Maternal education level, employment status, urban residency, and Christianity were statistically significant. This study establishes a connection between AMA and higher odds of cesarean section, gestational diabetes, pregestational diabetes, and pre-eclampsia. Women with AMA were more inclined to consume alcohol during pregnancy and exhibited preexisting conditions before conception. Moreover, AMA was linked to increased odds of low birth weight, stillbirths, and NICU transfers.

RESUMEN

Key Message: Although non-traumatic SDHs are uncommon during and immediately following pregnancy, management of these cases should be carried out by a multidisciplinary team, including obstetricians, pediatricians, neurosurgeons, and anesthesiologists. Abstract: Intracranial hemorrhage represents an uncommon but serious complication of pregnancy. Non-traumatic subdural hematomas (SDH) are uncommon during the prenatal period with limited literature about etiology and management. In this case report, the authors report on a patient with non-traumatic SDH in the third trimester of pregnancy. The patient is a 40-year-old G6P5L5 female at gestational age of 34 weeks and 5 days presenting with frontal headache, nausea, vomiting, and blurry vision. CT scan revealed an acute on chronic right subdural hematoma with midline shift and multiple herniations. An emergency cesarean section and right burr hole SDH evacuation were performed. Etiology of the SDH remains unknown. Although non-traumatic SDHs are uncommon during and immediately following pregnancy, health care providers should always consider this possibility if a patient presents with typical symptoms and signs. Management of these cases should be carried out by a multidisciplinary team, including obstetricians, pediatricians, neurosurgeons, and anesthesiologists to optimize maternal and fetal outcomes.

RESUMEN

INTRODUCTION: Maternal HIV infection is associated with increased risk of having a preterm delivery, low birth weight baby, small for gestational age baby and stillbirth. Maternal use of combination antiretroviral treatment is also associated with preterm delivery and low birth weight, although the effects vary by the type of drugs and timing of initiation. OBJECTIVE: To examine time trends in adverse perinatal outcomes among HIV-positive compared with HIV-negative women. DESIGN: Registry-based cohort study. SETTING: Northern Tanzania, 2000-2018. STUDY SAMPLE: Mother-baby pairs of singleton deliveries (n = 41 156). METHODS: Perinatal outcomes of HIV-positive women were compared with HIV-negative women during time periods representing shifts in prevention of mother-to-child transmission guidelines. Monotherapy was used as first-line therapy before 2007 while combination antiretroviral treatment was routinely used from 2007. Log binomial and quantile regression were used to analyze the data. MAIN OUTCOME MEASURES: Preterm delivery, low birth weight, perinatal death, stillbirth, low Apgar score, transfer to neonatal care unit and small for gestational age. RESULTS: Overall, maternal HIV infection was associated with a higher risk of low birth weight and small for gestational age. Moreover, this pattern became more pronounced over time for low birth weight, the last time period being an exception. For other outcomes we found none or only a small overall association with maternal HIV infection, although a trend towards higher risk over time in HIV-positive compared with HIV-negative women was observed for preterm delivery and perinatal death. Quantile regression showed an increase in birth weight in babies born to HIV-negative women over time and a corresponding decline in birth weight in babies born to HIV-positive women. CONCLUSION: Unfavourable trends in some of the selected perinatal outcomes were seen for HIV-positive compared with HIV-negative women. Potential side-effects of combination antiretroviral treatment in pregnancy should be further explored.

RESUMEN

Cervical cancer is the fourth most common malignancy in women of reproductive age globally. The burden of this disease is highest in low-income and middle-income countries, especially among women living with HIV. In 2018, WHO launched a global strategy to accelerate cervical cancer elimination through rapid scale-up of prophylactic vaccination, cervical screening, and treatment of precancers and cancers. This initiative was key in raising a call for action to address the stark global disparities in cervical cancer burden. However, achieving elimination of cervical cancer among women with HIV requires consideration of biological and social issues affecting this population. This Position Paper shows specific challenges and uncertainties on the way to cervical cancer elimination for women living with HIV and highlights the scarcity of evidence for the effect of interventions in this population. We argue that reaching equity of outcomes for women with HIV will require substantial advances in approaches to HPV vaccination and improved understanding of the long-term effectiveness of HPV vaccines in settings with high HIV burden cervical cancer, just as HIV, is affected by social and structural factors such as poverty, stigma, and gender discrimination, that place the elimination strategy at risk. Global efforts must, therefore, be galvanised to ensure women living with HIV have optimised interventions, given their substantial risk of this preventable malignancy.

RESUMEN

BACKGROUND: Human papilloma virus (HPV) is a sexually transmitted infection causing more than 80% of cervical cancers. WHO recommends using of sensitive screening methods like HPV-testing to timely prevent future morbidity and mortality from cervical cancer. Pilot studies have shown that HPV-testing is feasible and can be scaled in developing country like Tanzania. However, there is limited information on women understanding, reactions and psychological challenges following diagnosis of high risk HPV (HR-HPV). This study explored the knowledge of women on HPV and their experience after HPV positive results in Kilimanjaro, Tanzania. METHODS: The study was part of a larger study that assessed incidence and persistence of HR-HPV among women aged 18 years and above in Kilimanjaro. This was a cross sectional study conducted in Moshi municipal council among women who had HR-HPV positive results at enrollment. In-depth interviews were conducted with 13 randomly selected women who were attending for follow-up after enrollment. Interviews were conducted at the health facility and Atlas.ti.8 was used to analyze the data using thematic framework analysis. RESULTS: Women had knowledge on HPV infection but they had different reactions following receiving positive HPV results. Reaction toward the positive HPV results had two extremes; some women had psychological effect (hopeless, death sentence, having cancer, being shocked, failure to disclose and psychosexual effects) while others women explained positive results is good as they are identified earlier, will be followed up and it has made them plan to continue with cervical cancer screening in future. CONCLUSION: Women had knowledge on HPV, but positive results lead to negative and positive experiences by women. Clinicians and programs need to develop interventions and good strategies to minimize the psychological and social burden of testing positive for HPV.

RESUMEN

Cervical cancer is the most common female cancer in Eastern Africa, and the World Health Organization (WHO) recommends human papillomavirus (HPV)-based screening as a key element to eliminate the disease. In this cross-sectional study from Tanzania, we compared nine HPV-based cervical cancer screening strategies, including HPV testing at standard cut-off; HPV testing at increased viral load cut-offs; HPV testing with partial/extended genotyping, and HPV testing with visual inspection with acetic acid (VIA). We pooled data collected during 2008 to 2009 and 2015 to 2017 from 6851 women aged 25 to 65. Cervical cytology samples were HPV tested with Hybrid Capture 2, and HPV positive samples were genotyped with INNO-LiPA Extra II. Human immunodeficiency virus (HIV) testing and VIA were done according to local standards. We calculated sensitivity, specificity, positive and negative predictive value of screening strategies, with high-grade cytological lesions as reference, separately for women with and without HIV. HPV testing at standard cut-off (1.0 relative light units [RLU]) had highest sensitivity (HIV+: 97.8%; HIV-: 91.5%), but moderate specificity (HIV+: 68.1%; HIV-: 85.7%). Increasing the cut-off for HPV positivity to higher viral loads (5.0/10.0 RLU) increased specificity (HIV+: 74.2%-76.5%; HIV-: 89.5%-91.2%), with modest sensitivity reductions (HIV+: 91.3%-95.7%; HIV-: 83.5%-87.8%). Limiting test positivity to HPV types 16/18/31/33/35/45/52/58 improved specificity while maintaining high sensitivity (HIV+: 90.2%; HIV-: 81.1%). Triage with VIA and/or partial genotyping for HPV16/18 or HPV16/18/45 had low sensitivities (≤65%). In conclusion, HPV testing alone, or HPV testing with extended genotyping or increased viral load cut-offs, may improve cervical cancer screening in Sub-Saharan Africa.

RESUMEN

OBJECTIVE: There is a concern about performance of the screening approaches, where information on the quality of novel and affordable screening approaches that will perform well in remote areas is warranted. This lack of information makes it difficult to prioritise resource use in efforts to improve cervical cancer outcomes. We aimed to compare the diagnostic value of human papillomavirus (HPV) testing on self-collected samples, Pap smear and visual inspection of the cervix with acetic acid (VIA) tests for detection of high-grade cervical intraepithelial neoplasia or worse (CIN2+). DESIGN: A combined cross-sectional and cohort study. SETTING: Three primary healthcare centres in Kilimanjaro region, Tanzania. PARTICIPANTS: 1620 women undergoing cervical cancer screening from December 2018 to September 2021. Inclusion criteria were being aged 25-60 years, and no history of premalignant or cervical cancer. Exclusion criteria were overt signs of cancer and previous hysterectomy. INTERVENTIONS: Participants underwent HPV self-sampling with Evalyn Brush and Care HPV kit assay was used to determine prevalence of high-risk HPV infection. Women with positive HPV test were together with a random sample of HPV negative women scheduled for follow-up where VIA was performed, and Pap smear and cervical biopsies obtained. RESULTS: Of 1620 women enrolled, 229 (14.1%) were HPV positive and 222 of these attended follow-up together with 290 (20.8%) women with negative HPV test. On VIA, 17.6% were positive. On Pap smear, 8.0% were classified as high-grade squamous intraepithelial lesion. The sensitivity and specificity, respectively, of the various tests, compared with histopathology for the detection of CIN2+ were: HPV test 62.5%, 59.3%; Pap smear 82.8%, 82.1% and; VIA 48.4%, 56.8%. When combined, the sensitivity and specificity for HPV and Pap smear were 90.6%, 70.6% while HPV and VIA were 65.6% and 75.5% for the detection of CIN2+. CONCLUSIONS: The performance of care HPV testing on self-collected samples opens the possibility of increasing coverage and early detection in resource-constrained settings.

RESUMEN

INTRODUCTION: Globally, evidence suggests that one-third of nulliparous women experience delay in the first stage of labor with an increased risk of poor maternal and neonatal outcomes. With this study, we explore how clinical challenges related to prolonged labor are perceived by nurse-midwives and doctors in Tanzania. METHODS: A qualitative study with group interviews of either nurse-midwives (7 interviews) or doctors (2 interviews). A total of 37 respondents, among them 32 registered nurse-midwives and 5 doctors participated, all with experience from labor wards. A qualitative content analysis was performed. The study setting comprised one zonal consultant university hospital and one regional referral hospital in Northern Tanzania. RESULTS: Clinical challenges were expressed in relation to: 1) various ways of understanding prolonged labor, manifested by variations in expected duration of labor and the usage of different terms to describe prolonged labor; 2) assessing progress in labor, the partograph being described as an important tool but also a template defining a too narrow normal; 3) appropriate intervention at the appropriate time, the respondents reflect on the correct time for artificial rupture of membranes, oxytocin augmentation and cesarean section; 4) monitoring fetal heart rate, distrust in the monitoring equipment with experiences of surprisingly poor neonates; and 5) working as a team, where the perception of urgency varies and distrust is present. CONCLUSIONS: Nurse-midwives and doctors in Tanzania face major challenges related to diagnosing prolonged labor, monitoring fetal heart rate and providing high quality health services as a team.

RESUMEN

BACKGROUND: High-risk (HR) human papillomavirus (HPV) persistence is the most important risk factor for cervical cancer. We have assessed the type-specific HR HPV persistence among HIV positive and HIV negative Tanzanian women and factors associated with HR HPV persistence. METHODS: In a cohort study including 4080 Tanzanian women, 3074 attended follow-up examination (up to 32 months after enrollment). Cervical samples were obtained for liquid-based cytology and HPV DNA testing using Hybrid Capture 2 and Inno-Lipa Extra II. Information on lifestyle factors was collected through a personal interview. The probability of HR HPV persistence at a given time point since enrollment was estimated non-parametrically using the EMICM algorithm. RESULTS: Among the 462 women HR HPV positive at enrollment, 158 had at least one identical type detected at follow-up. The probability of persistence at 18 months after enrollment was 34.2 (95% CI 29.0-39.4). Stratifying by HIV status, the persistence probability was 42.9% (95% CI 33.5-51.9) among HIV positive, and 28.0% (95% CI 22.1-34.2) among HIV negative. Overall, HR HPV persistence was most common for HPV58, 35, 16, 31, and 52. Among HIV positive women it was HPV45, and HPV16, followed by HPV58 and HPV18, and among HIV negative women it was HPV31, HPV33 and HPV58. Risk factors associated with persistence of HR HPV were older age, longer interval between enrollment and follow-up, binge drinking, and HIV status. CONCLUSIONS: HR HPV persistence was common in Tanzania, and most common among HIV positive women. Overall, persistence was most frequent for HPV 58, 35, 16, 31 and 52. The nonavalent HPV vaccine should be considered.

RESUMEN

BACKGROUND: Caesarean delivery (CD) is the commonest obstetric surgery and surgical intervention to save lives of the mother and/or the new-borns. Despite been accepted as safe procedure, caesarean delivery has an increased risk of adverse maternal and fetal outcomes. The rising rate of caesarean delivery has been a major public health concern worldwide and the consequences that come along with it urgently need to be assessed, especially in resource limited settings. We aimed to examine the relationship between first birth caesarean delivery and adverse maternal and perinatal outcomes in the second pregnancy among women who delivered at a tertiary hospital in Northern Tanzania. METHODS: A retrospective cohort study was conducted using maternally-linked data from Kilimanjaro Christian Medical Centre. All women who had singleton second delivery between the years 2011 to 2015 were studied. A total of 5,984 women with singleton second delivery were analysed. Multivariable log-binomial regression was used to determine the association between first caesarean delivery and maternal-perinatal outcomes in the second pregnancy. RESULTS: Caesarean delivery in the first birth was associated with an increased risk of adverse maternal and perinatal outcomes in the second pregnancy. These included repeated CD (ARR 1.19; 95% CI: 1.05-1.34), pre/eclampsia (ARR 1.38; 95% CI: 1.06-1.78), gestational diabetes mellitus (ARR 2.80; 95% CI: 1.07-7.36), uterine rupture (ARR 1.56; CI: 1.05-2.32), peri-partum hysterectomy (ARR 2.28; CI: 1.04-5.02) and preterm birth (ARR 1.21; CI: 1.05-1.38). CONCLUSION: Caesarean delivery in their first pregnancy had an increased risk of repeated caesarean delivery and other adverse maternal-perinatal outcomes in the following pregnancy. Findings from this study highlight the importance of devising regional specific measures to mitigate unnecessary primary caesarean delivery. Additionally, these findings may help both clinicians and women in deciding against or for trial of labor after previous caesarean delivery in an event of absent direct obstetric indication.
