A rare metastatic region of cervical cancer; the brain: a case report

Cervical cancer metastasizes commonly to the bone, lungs, liver and the supraclavicular lymph nodes. Rare sites of metastasis the brain, breast, paraspinal muscles, duodenum and heart have been reported. Case report: A 53-year-old postmenopausal woman presented to our facility with a one-month history of vaginal bleeding. She was found to have an exophytic cervical mass on pelvic examination. She was managed as a case of stage IIIB cervical cancer. Histology revealed Squamous Cell Carcinoma type. She had radiotherapy and was symptoms free. She represented 3 months later with visual disturbance, headache and vomiting. She was found to have metastatic lesion to her brain. She survived for 3 months and 3weeks after first treatment. Conclusion: The prognosis of cervical cancer patients with brain metastases is frequently poor with median survival of only a few months such as in this case who survived 3 months and 3 weeks after first treatment. Only few reports have incidences of long-term, disease-free survival in these patients

Pattern of prostate cancer among a Nigerian population: A study in a single tertiary care centre

Background: Prostate cancer has become a global health challenge because of its rising morbidity and mortality in males.It is the second cause of cancer death following lung cancer in men.It is rare under the age of 40 and its incidence has been shown to increase exponentially with age. Previously, Prostate cancer was thought to be a disease rare in blacks owing to the fact that not so much was known of the disease.Aim and objectives: The objective of the study was to review the prevalence, pattern of presentation and clinic-pathologic findings of prostate cancer in the Department of Radiotherapy,Lagos University Teaching Hospital (LUTH),between January 2001 to December 2010 in comparison to previous and recent studies globally.Methodology: Data collection for all patients histologically diagnosed with Prostate cancer at the Department of Radiotherapy,LUTH,from 1st of January 2001 to 31st of December 2010 was done.Results: A total of 144 cases with histologically confirmed Prostate cancer seen during the ten year study were analysed.The highest frequency was seen in the year 2010 with 34 cases.The age range was 41 to 81years with a mean of 66.19 ±7.30years.Adenocarcinoma was the commonest histological type with 98.6%.9(6.3%) patients had a positive family history of prostate cancer out of which 3(33.3%) had their brother affected the malignancy. 51(35.4%) patients presented with stage IV disease.18(12.5%) patients had a Gleason's score of 6,10(6.9%) patients had a Gleason's score of 7 and 2(1.4%) patients had a Gleason's score of 10. The most common presenting complaints were bone pains seen in 51(35.4%) patients, frequent night urine and difficulty with micturition seen in 50(34.7%) and 42(29.2%) patients respectively.Conclusion: This study showed that prostate cancer is not as rare as it used to be.Reasons attributed to its rarity then were lack of awareness,poor screening facilities and poor diagnosing technique.Keywords: prostate cancer,presentation,tumour characteristics,Nigeri

The ‘evil arrow’ myths and misconceptions of cancer at Lagos University Teaching Hospital, Nigeria

Background: Myths and misconceptions have significant impact on the presentation and management of cancers globally. One such example includes ‘evil arrow’ myths. There is limited knowledge regarding the role of misconceptions in late presentation for management in developing countries. The percentage increase in cancers in many African countries is higher than that in developed countries. Evil arrow is the seeming attack of the enemy in a supernatural version as a result of wizardry. Aim: To evaluate the relationship of common myths and misconceptions among cancer patients, their treatment and delay of presentation to the hospital. Setting: The study was undertaken in a tertiary health facility in a cosmopolitan tropical state. Method: This is a randomised observational survey study carried out among patients and their relatives referred to the Radiotherapy Clinic of the Lagos University Teaching Hospital for treatment (a lower-income mixed metropolitan setting). A self-administered questionnaire was used. Patient consent was obtained. Data were analysed with Epi Info 2002 software and the results were presented using frequency tables and charts. Results: About 57 were patients (67%) and 28 were patients’ relatives (33%). The age distribution of participants showed 31–40 years (31.8%; 27) as the highest number, while 11–20 years (1.2%; 1) was the lowest number. A slight female preponderance of 58.8% (50) was observed. High incidence of those with the opinion that cause of cancer is unknown represented 63% (54). Over 65% of patients presented with advanced disease. The reasons for late presentation to the hospital included lack of funds in 23.5% of patients (20). Conclusion: Lack of funds, myths and misconception are main reasons why patients presented late to hospital. There is a need to emphasise debunking innumerable myths and misconceptions associated with cancer

Structure: Activity and Emerging Applications of Spices and Herbs

Herbs and spices are plant parts (herbs from leaves and spices from other parts) that are conventionally used in their fresh or dried state for flavouring, natural condiments, preservatives and for medicinal purposes. Worldwide, most spices are classified on the basis of taste, season of growth, economic importance, growth habit and plant part used. Black pepper, chilies, small cardamom, ginger and turmeric are some of the widely used spices while common herbs include thyme, basil and bay leaves. These herbs are basically classified according to usage, active constituents and period of life. Secondary metabolites such as Eugenol, thymol, limonene, cuminaldehyde, curcumin, piperine, quercetin, luteolin in these plant parts have been found to be responsible for anticancer, antimicrobial, antiviral, antidiabetic, antioxidant, anti-inflammatory and hypocholesterolemic effects. Their application in water fortification, milk and cheese processing, production of beauty products and pesticides among others could not be underestimated. Finally, adulteration, toxicity and allergic reactions are some of the identified limitations and challenges often encountered in the use of herbs and spices

MasakhaNER 2.0: Africa-centric Transfer Learning for Named Entity Recognition

African languages are spoken by over a billion people, but are underrepresented in NLP research and development. The challenges impeding progress include the limited availability of annotated datasets, as well as a lack of understanding of the settings where current methods are effective. In this paper, we make progress towards solutions for these challenges, focusing on the task of named entity recognition (NER). We create the largest human-annotated NER dataset for 20 African languages, and we study the behavior of state-of-the-art cross-lingual transfer methods in an Africa-centric setting, demonstrating that the choice of source language significantly affects performance. We show that choosing the best transfer language improves zero-shot F1 scores by an average of 14 points across 20 languages compared to using English. Our results highlight the need for benchmark datasets and models that cover typologically-diverse African languages
