Rupture of the Gravid Uterus: A Two-Decade Experience at a University Teaching Hospital in South-West, Nigeria.

BACKGROUND: Uterine rupture is an obstetric emergency associated with significant maternal and perinatal mortality and morbidity, especially in resource-constraint countries such as Nigeria. OBJECTIVE: To determine the incidence and feto-maternal outcome of uterine rupture in a Nigerian teaching hospital. METHODS: This was a retrospective review of all cases of uterine rupture managed over 21 years. The case notes of all affected women were retrieved, and information on sociodemographic and obstetric characteristics, clinical presentation, intraoperative findings, and fetal and maternal outcomes were extracted. Data were analyzed using SPSS version 23.0 and descriptive statistics were computed. Factors associated with maternal deaths secondary to rupture of the gravid uterus were determined using binary logistic regression analyses. Statistical significance was reported at P<0.05. RESULTS: There were 31,616 deliveries during the review period, out of which were 182 cases of uterine rupture giving an incidence of 5.76 per 1,000 deliveries. Most of the cases of uterine rupture (65.2%) were treated by uterine repair. Maternal and fetal deaths were recorded in 8.1% and 82.7% of cases respectively. Women aged at least 35 years (P=0.035), women who had laboured at home or traditional birth attendant's (TBA) place (P=0.002), women who had multiple sites rupture (P=0.049) and those who developed hypovolemic shock (P=0.002) were more likely to die from uterine rupture. CONCLUSION: Ruptured uterus remains a significant cause of maternal and perinatal morbidity and mortality in Nigeria. Strategies for prevention include effective health education of the masses, the conduct of labour in a well-equipped health facility, and prompt referral of at-risk women.

CONTEXTE: La rupture utérine est une urgence obstétrique associée à une mortalité et une morbidité maternelles et périnatales significatives, en particulier dans les pays à ressources limitées comme le Nigeria. OBJECTIF: Déterminer l'incidence et l'issue fœto-maternelle de la rupture utérine dans un hôpital universitaire nigérian. MÉTHODES: Il s'agit d'une étude rétrospective de tous les cas de rupture utérine pris en charge sur une période de 21 ans. Les notes de cas de toutes les femmes concernées ont été récupérées et des informations sur les caractéristiques sociodémographiques et obstétriques, la présentation clinique, les résultats peropératoires et les issues fœtales et maternelles ont été extraites. Les données ont été analysées à l'aide de la version 23.0 de SPSS et des statistiques descriptives ont été calculées. Les facteurs associés aux décès maternels consécutifs à la rupture de l'utérus gravide ont été déterminés à l'aide d'analyses de régression logistique binaire. La signification statistique a été rapportée à P<0,05. RÉSULTATS: Il y a eu 31 616 accouchements pendant la période examinée, dont 182 cas de rupture utérine, soit une incidence de 5,76 pour 1 000 accouchements. La plupart des cas de rupture utérine (65,2 %) ont été traités par réparation utérine. Les décès maternels et fœtaux ont été enregistrés dans 8,1% et 82,7% des cas respectivement. Les femmes âgées d'au moins 35 ans (P=0,035), les femmes ayant accouché à domicile ou chez une accoucheuse traditionnelle (P=0,002), les femmes ayant eu des ruptures multiples (P=0,049) et celles ayant développé un choc hypovolémique (P=0,002) étaient plus susceptibles de mourir d'une rupture utérine. CONCLUSION: La rupture de l'utérus reste une cause importante de morbidité et de mortalité maternelles et périnatales au Nigeria. Les stratégies de prévention comprennent une éducation sanitaire efficace des masses, la conduite du travail dans un établissement de santé bien équipé et l'orientation rapide des femmes à risque.

Prognostic impact of pretreatment thrombocytosis in epithelial ovarian cancer.

AIMS: This study was aimed at investigating the prognostic impact of pretreatment thrombocytosis in epithelial ovarian cancer (EOC) patients in Lagos, Nigeria. METHODS: This was a retrospective cohort study involving the review of the clinical record of 72 patients with histologically confirmed EOC who were managed at the Lagos University Teaching Hospital, Lagos, Nigeria over a 7-year period from January 2010 to December 2016. Information on the sociodemographic data and platelet counts at diagnosis of EOC were retrieved from the patients' medical records. Descriptive statistics were then computed for all baseline patients' characteristics. Survival analyses were carried out using the Kaplan-Meier estimates. Multivariate analysis of these data was performed with the Cox proportional hazards model. RESULTS: This study revealed that the prevalence of pretreatment thrombocytosis was 41.7% among the women with EOC. Fifty-three (73.6%) of the women had the advanced-stage disease (FIGO stage III-IV) while 52 (72.2%) had high-grade disease (II-III). The majority (66.7%) of the women had a serous histological type of EOC while 76.4% had documented recurrence. Pretreatment thrombocytosis was significantly associated with the women's parity (P = 0.009), serum carbohydrate antigen 125 levels (P = 0.018), median progression-free survival (PFS) (P < 0.001), 3-year median overall survival (OS) (P < 0.001), type of primary treatment (P = 0.002), extent of cytoreduction (P < 0.001), presence of ascites (P = 0.002), International Federation of Gynecology and Obstetrics (FIGO) stage (P = 0.008), and histological type (P = 0.011). Pretreatment thrombocytosis was negatively associated with PFS (hazard ratio [HR] = 0.25; 95% CI 0.83, 0.75; P = 0.014) and 3-year OS (HR = 0.03; 95% CI 0.03, 0.27; P = 0.002). CONCLUSIONS: The study suggests that pretreatment thrombocytosis may be a useful predictor of survivals in EOC patients.

Association between Serum Homocysteine Levels in Preeclampsia and its Severity among Women in Lagos, South-West Nigeria.

BACKGROUND: Clinical evidence had suggested that hyperhomocysteinaemia features in hypertensive disorders of pregnancy. However, there is still conflicting evidence on the extent to which elevated maternal homocysteine contributes to this deadly complication of pregnancy. OBJECTIVES: This study investigated the impact of elevated maternal homocysteine levels in early pregnancy on preeclampsia and its severity among Nigerian women in Lagos. METHODS: This was a prospective cohort study conducted at the Lagos University Teaching Hospital. Participants were enrolled in the first trimester of pregnancy following which their sociodemographic data were obtained by interview. Venous blood samples were collected for measurement of homocysteine concentration using the ELISA method. Data on the occurrence of preeclampsia was obtained from the delivery records. Binary logistic regression model was used to study the effects of the major baseline characteristics on the development of preeclampsia. RESULTS: The final analysis included 167 patients; hyperhomocysteinaemia was recorded in 24 (24.6%) patients. Women with hyperhomocysteinaemia had no statistically significant risk of developing preeclampsia or severe preeclampsia, compared with women with a normal homocysteine concentration. CONCLUSION: The prevalence of hyperhomocysteinaemia in the study was relatively low. The absence of a significant association between maternal hyperhomocysteinaemia and preeclampsia reported in this study could create room for the conduct of a more robust, adequately powered longitudinal research needed to answer some of the major reservations that remain from the present study.

Promoting cancer control training in resource limited environments: Lagos, Nigeria.

In resource limited nations, cancer control is often a lower priority issue creating challenges for the prevention, early diagnosis, and treatment of cancer. Training and education are vital components of efforts to tackle this problem. A 3-day cancer control workshop was conducted at the Lagos State University Teaching Hospital (LASUTH), Nigeria, in 2013. The curriculum included didactic lectures, panel discussions, and interactive sessions on local cancer statistics, preventive strategies, cancer registries, screening and diagnostic options, and treatment approaches with limited resources (chemotherapy, radiotherapy, surgery, and palliative care) and several site-specific (breast, lung, cervical, prostate, and colon) topics. Pre-workshop and post-workshop questionnaires were completed by participants. Eighty-six percent of the 50 workshop participants completed at least one questionnaire. Participants were mainly nurses and physicians (89% of responders), and 40% reported >25 years of practice experience. The more common local needs identified were professional education (65%) and increasing public cancer awareness (63%). The greatest interest for future programs was on research collaborations (70%). An immediate impact of the workshop was the commencement of monthly tumor board conferences and a review of the current cancer registry data. Capacity building is critical for the execution of effective cancer control strategies. Conducting collaborative workshops represents a cost-effective means of launching programs and energizing the medical community to pursue ongoing education and research addressing the anticipated cancer epidemic on the African continent.

Regional cancer control in south-eastern Nigeria: a proposal emanating from a UICC-sponsored workshop.

There is an impending cancer epidemic in Africa. In Nigeria, this disease is causing untold devastation, and control measures are desperately needed. Breast, cervical, prostate, and liver cancers are the most common types in Nigerian adults. In children, the predominant malignant diseases are Burkitt's lymphoma, acute lymphoblastic leukemia, neuroblastoma, and Wilm's tumor (nephroblastoma). The focus of efforts to control cancer in Nigeria should be directed at prevention with adequate attention to planning/policy making, early detection, accurate diagnosis, treatment and palliative care. National and regional allocation of sufficient resources is required, accompanied by measurable objectives and appropriate emphasis on accountability.

Epidermal growth factor receptor-directed therapy in esophageal cancer.

Esophageal adenocarcinoma (EAC) is one of the fastest growing malignancies in the US. The long-term survival of patients with this cancer remains poor; only 25% of patients undergoing surgical excision are alive after 5 years. Multimodal programs that incorporate radiotherapy, chemotherapy and surgery for localized tumors may result in a modest survival advantage. However, significant strides in this disease can result from the inclusion of targeted therapies. The epidermal growth factor receptor (EGFR) family represents one such target and is receiving increasing attention due to the advent of specific inhibitors. Studies conducted by us and others have shown that the overexpression of EGFR family signaling intermediates is common in Barrett's esophagus and EAC. In the latter case, EGFR expression may have prognostic significance. EGFR inhibitors, including oral tyrosine kinase inhibitors and monoclonal antibodies, result in a synergistic antitumor effect with chemotherapeutic agents or with radiotherapy. Therefore, several ongoing studies include EGFR-directed therapy either alone or in combination with chemoradiotherapy for this disease. Our study of gefitinib, oxaliplatin and radiotherapy suggested that gefitinib can be safely incorporated into an oxaliplatin-based chemoradiation program for esophageal cancer, although the clinical activity of this combination is modest. Herein, we review the current literature on this subject.

Management of locoregional stage esophageal cancer: a single center experience.

Therapeutic options for locoregional esophageal cancer (EC) include primary surgery, neoadjuvant or definitive chemoradiation and systemic chemotherapy. The role of surgery in these multimodal strategies has recently been debated and definitive chemoradiation is being offered as an alternative to surgery at many centers. We examined our results with multimodal therapy and surgery in this patient population. We conducted a retrospective analysis of 172 patients with locoregional (AJCC stages I-III) EC treated at RPCI between February 14, 1990 and September 20, 2002. Median age was 65 years (range, 36-95); there were 136 male patients. There were 100 regional (stages IIB-III), 69 local (stages I-IIA) and three in situ cases. Initial therapy was either combined modality (n = 122) or single modality (surgery) (n = 50). There was 0%, 30-day, postoperative mortality. Median survival for all patients was 25.3 months and was better for local stage with surgery alone (75 months) than with neoadjuvant (35.7 months) or definitive chemoradiation (19.1 months, P < 0.001). Survival for patients with regional disease treated with surgery alone, neoadjuvant or definitive chemoradiation was 21.5, 24.4 and 11.8 months, respectively (P = not significant). The associations of prognostic factors with overall survival were evaluated using Cox proportional hazards regression analysis and 2-sided Wald's chi-square test. On multivariate analysis, carefully selected patients treated with surgery alone had better outcomes compared with those treated with definitive chemoradiation (P < 0.001). Patients with locoregional esophageal cancer who are eligible for surgical resection either alone or as a part of multimodal therapy may have better outcomes than those treated with non-surgical approaches.

Comparison of human lung cancer/SCID mouse tumor xenografts and cell culture growth with patient clinical outcomes.

Leukemic cell growth in SCID mice has been reported as a predictor of disease relapse. However, there is a paucity of literature regarding xenograft growth and clinical outcomes in non-small cell lung cancer (NSCLC). Seventy-nine specimens from patients with NSCLC were either subcutaneously implanted into SCID mice and/or placed in tissue culture. Retrospective chart review was correlated with stage, histology, necrosis, disease-free interval, and survival. Tumor xenografts were successfully established with 17 of 37 (46%) tumor biopsy tissues. Thirteen of 59 (22%) specimens grew in cell culture. Patients whose tumors grew in SCID mice had no difference in survival compared to those with no growth ( n=20, p=0.42). Median survival was 36 months in 13 patients whose tumors grew in cell culture compared to 39 months in 46 patients without growth. Eight of 12 (67%) patients with metastasis showed SCID/human xenograft growth, whereas nine of 25 (36%) without metastases did so ( p=0.08). Growth of tumor cells in vitro occurred in 11 of 31 (35%) adenocarcinomas, one of 25 (4%) squamous cell carcinomas, and one of three (33%) large cell carcinomas ( p=0.02). Well or moderately differentiated tumors grew in cell culture in only two of 22 (9%), whereas poorly or undifferentiated tumors grew in 11 of 32 (34%) cases ( p=0.03). We conclude that neither the ability of a tumor to engraft and grow in SCID mice nor its ability to grow in vitro in cell culture is a reliable predictor of disease outcome or survival in patients with NSCLC. The ability to propagate tumors in vitro appears to be more dependent upon the histological type of tumor and its degree of differentiation.

Pulmonary resection in metastatic uterine and cervical malignancies.

OBJECTIVE: Although thoracotomy for removal of pulmonary metastasis is well documented in a wide variety of solid tumors, data are sparse regarding management of patients with gynecologic malignancies metastatic to the lung. METHODS: We retrospectively reviewed the Roswell Park Cancer Institute experience between 1982 and 1999. Of 82 eligible patients with gynecologic tumors metastatic and confined to the lung, 25 underwent pulmonary resection. RESULTS: There were 60 uterine and 22 cervix cancer patients with pulmonary metastases. Among patients with uterine cancer primaries undergoing pulmonary resection (n = 19) median survival was 26 months. Uterine cancer patients who underwent surgical resection for leiomyosarcomas (n = 11) had a median survival of 25 months compared to 46 months in patients with adenocarcinoma (n = 6, P = 0.02). Median survival in cervix cancer patients undergoing resection for pulmonary metastases (n = 6) was 36 months. CONCLUSIONS: Pulmonary resection may provide a survival advantage for selected patients with uterine and cervical malignancies with metastases isolated to the lung.

The surgical management of pulmonary metastasis: current concepts.

Lung metastases have been found in 25-30% of all patients with cancer at autopsy. Those patients satisfying criteria for surgical resection represent a much smaller subgroup. Given the potentially curative nature of pulmonary metastasectomy in the absence of disseminated disease, it has become widely accepted as an important treatment option for a variety of malignancies with metastasis to the lungs. A standardized approach remains unfounded however, given limited numbers of patients, various histologic subtypes and few published studies utilizing randomized prospective methodology.Ultimately, the development of metastasis represents a major determinant of survival for patients with cancer. Pulmonary metastasectomy is an important treatment modality for patients with metastatic pulmonary disease. The indications for pulmonary metastasectomy and the surgeon's role in pulmonary metastatic disease continue to evolve. Future prospective studies and the compilation of comparable data yielding prognostic factors for specific histologies will better define indications for resection.

Pericardial catheter sclerosis versus surgical procedures for pericardial effusions in cancer patients.

BACKGROUND: Approximately 21% of patients with advanced malignancies have cardiac or pericardial involvement with tumor. Controversy exists regarding the optimal approach to the pericardial space when hemodynamic compromise due to effusions occurs. METHODS: A six-year retrospective review of 59 cancer patients with pericardial effusions. RESULTS: Thirty-six patients had subxiphoid pericardial window (SXPW) alone (Group A), 5 had pericardial catheter drainage (PCD) followed by a SXPW (Group B), 10 had PCD with sclerosis (Group C), 5 had PCD alone (Group D), 2 had PCD with pericardial-pleural window (Group E), and one had pericardial-peritoneal window (Group F). The method of procedure, complications, number of hospital and ICU days, cytological or pathologic evidence of malignancy, solid versus hematological tumors, and survival were analyzed. The median survival for those patients in group C was one month compared to 4 months for Group A and 6 months for Group B. Essentially, results were similar regardless of method performed with the exception that professional and hospital charges averaged $4830 for SXPW compared to $1625 for PCD. CONCLUSIONS: Pericardial catheter drainage and sclerosis provides a viable option for the treatment of pericardial effusions in selected cancer patients at markedly reduced cost and patient discomfort.

Iatrogenic esophagobronchial fistula arising in irradiated Barrett's esophagus.

A 47-yr-old male underwent a right upper lobectomy for stage IIB bronchoalveolar carcinoma followed by 4600 Gy of irradiation. One year later a fistula formed from an ulcerated region of Barrett's esophagus into the left main bronchus. Bronchotomy repair with onlay patch intercostal muscle flap and esophageal repair with serratus anterior muscle flap plus postoperative esophageal stent placement for stricture resulted in good functional results.

Acute submucosal esophageal hemorrhage.

Two cases of acute submucosal esophageal hemorrhage are reported. This condition is uncommon and presents an urgent diagnostic dilemma. Its presentation, diagnosis, and management are reviewed. The underlying pathology and causative factors are researched and clarified. Conservative management is safe and effective.

Gallstone shrapnel contamination during laparoscopic cholecystectomy.

The fate of lost gallstones in the peritoneal cavity following laparoscopic cholecystectomy is unknown. We report a case of microabscesses and granuloma formation in the peritoneal cavity and abdominal wall caused by infected gallstone shrapnel due to rupture of the gallbladder during extraction.
