Introduction: Breastfeeding is essential for optimum childhood development. Although there is an increased awareness of the importance of breast milk, the Nigerian Demographic and Health Survey of 2018 showed that less than one-third (29%) of mothers in Nigeria practice exclusive breastfeeding. This may be attributed to several factors, hence the need for this study to assess the indicators and predictors of breastfeeding practices among mothers in a tertiary facility in Calabar, Cross River State. Methods: This cross-sectional study was conducted in the University of Calabar Teaching Hospital, Calabar, Nigeria. Consenting mothers of children aged six weeks to two years were sequentially recruited into the study using an interviewer-administered questionnaire. A test of association of categorical variables was done using Chi square test and pvalue was set at 0.05. Results: One hundred and twenty one children and their mothers were surveyed. Mean age of children was 6.2±3.8months and mothers was 28±25years. Exclusive breastfeeding rate for six months was 67.8%.Timely breastfeeding within one hour of life was 44.6%,ever breastfed rate was 86%. Practice of giving water alongside breast milk and use of breast milk substitute was 18.2% and 14.0% respectively. Mothers age was significantly associated with practice of exclusive breastfeeding (p=0.014) and giving water alongside breast milk (p=0.005) while birth order was associated with timely commencement of breastfeeding within one hour of life (p=0.022). Conclusion: The ever breastfed and exclusive breastfeeding rates were fairly high. However, the timely first suckling rate, increased use of breast milk substitute and giving of water alongside breast milk in the first six months of life were low. There is the need for continuous health education of mothers.
母乳喂养对儿童的最佳发育至关重要。尽管人们对母乳重要性的认识有所提高,但2018年尼日利亚人口与健康调查显示,尼日利亚只有不到三分之一(29%)的母亲实行纯母乳喂养。这可能归因于几个因素,因此有必要进行这项研究,以评估克罗斯河州卡拉巴尔一家三级机构中母亲母乳喂养做法的指标和预测因素。方法:本横断面研究在尼日利亚卡拉巴尔卡拉巴尔大学教学医院进行。孩子年龄在6周至2岁之间的同意母亲被依次招募到研究中,使用的是一份由访谈者填写的问卷。分类变量的相关性检验采用卡方检验,p值设为0.05。结果:对121名儿童及其母亲进行了调查。患儿平均年龄6.2±3.8个月,母亲平均年龄28±25岁。6个月纯母乳喂养率为67.8%。1小时内及时母乳喂养率为44.6%,曾经母乳喂养率为86%。在母乳中喝水和使用母乳替代品的比例分别为18.2%和14.0%。母亲的年龄与纯母乳喂养(p=0.014)和饮水与母乳(p=0.005)显著相关,而出生顺序与在出生后1小时内及时开始母乳喂养(p=0.022)相关。结论:母乳喂养率和纯母乳喂养率均较高。然而,在生命的前六个月,及时的第一次哺乳率,母乳替代品的使用增加以及在母乳中给予水的情况很低。有必要对母亲进行持续的健康教育。

A revised scoring scheme for the classification of socio-economic status in Nigeria 修订后的尼日利亚社会经济地位分类计分方案
Pub Date : 2021-02-04 DOI: 10.4314/NJP.V48I1.5

Background: Researchers in medicine and related fields in Nigeria have usually made recourse to the instrument developed by Olusanya et al and Oyedeji in the past three-and-a half decades for determination of socioeconomic status (SES). Beside the question of their age, however, these instruments were purposive and might no longer be suitable because of the changes in the parameters on which they were based.Objective: To develop a robust but generic scheme that takes into consideration the changes in the nation’s socioeconomic space in the succeeding three and a half decades.Methods: A detailed and comprehensive review of the extant schemes was undertaken with a view to identifying their inherent weaknesses. The latter were then factored into the design of a new scheme taking into consideration the emergent restructuring of career positions in the civil/public service as well as the place of private and informal sectors of the economy. The new scheme was validated at the University of Beninand Irrua Specialist Teaching Hospitals.Results: The new scheme had a remarkably high Inter-rater reliability (r = 0.947, p<0.001), raterre- rater reliability (r = 0.984, p <0.001) and % agreement (with modified Oyedeji’s tool as standard) of 67% (K coefficient = 0.47, r = 0.71, p<0.001)Conclusion/Recommendation: The new scheme could be a viable tool for the assessment of SES of families and individuals, which not only takes into consideration current realities of the nation’s economy, but also is readily adaptable to meet foreseeable changes.
背景:尼日利亚医学和相关领域的研究人员通常求助于Olusanya等人和Oyedeji在过去35年中开发的工具来确定社会经济地位(SES)。然而,除了它们的年龄问题外,这些工具是有目的的,由于它们所依据的参数发生了变化,它们可能不再适用。目的:制定一个健全但通用的方案,考虑到国家社会经济空间在未来35年的变化。方法:对现有计划进行了详细和全面的审查,以确定其固有的弱点。然后,在设计一项新计划时考虑到公务员/公务员制度中职业职位的紧急改组以及私营和非正式经济部门的地位,将后者考虑在内。新方案在贝宁大学和伊鲁阿专科教学医院得到验证。结果:新方案具有较高的量表间信度(r = 0.947, p<0.001)、量表间信度(r = 0.984, p<0.001)和符合率(以改良Oyedeji工具为标准)为67% (K系数= 0.47,r = 0.71, p<0.001)。新方案可能是评估家庭和个人SES的可行工具,它不仅考虑到国家经济的当前现实,而且易于适应可预见的变化。

GM1-gangliosidosis in a Nigerian infant: A case report 尼日利亚婴儿gm1神经节脂质沉积症1例报告
Pub Date : 2021-02-04 DOI: 10.4314/NJP.V48I1.10

Gangliosidoses belong to the group of genetic lipid metabolism disorders, caused by defects of lysosome enzymes, inherited as an autosomal recessive trait. Gangliosidosis GM1 is caused by the deficiency of the acid beta-galactosidase (GLB11) resulting in the storage of the substrate- GM1 ganglioside in brain and visceral organs. GM1 gangliosidosis comprises three phenotypes, depending on the age of onset: an infantile, juvenile and adult type. In the infantile type dysmorphic features, severe psychomotor retardation, hepatosplenomegaly, bone changes and a cherry red spot in the macular region are seen. The juvenile GM1 gangliosidosis has no such external distinguishing features. In the adult type behavioural problems, dementia, extrapyramidal problems are specifically prominent. The authors present symptoms, clinical course and laboratory findings of a one-year-old boy with a diagnosed GM1 gangliosidosis. He presented with skin rashes since birth, delay in achievement of developmental milestones, progressive weight loss and recurrent diarrhoea of six-months duration.
神经节脂质剂量是一种由溶酶体酶缺陷引起的遗传性脂质代谢紊乱,是一种常染色体隐性遗传性状。神经节苷脂病GM1是由酸性-半乳糖苷酶(GLB11)缺乏引起的,导致底物- GM1神经节苷脂在脑和内脏器官中储存。GM1神经节脂质病包括三种表型,取决于发病年龄:婴儿型,青少年型和成年型。在婴儿型畸形特征中,可以看到严重的精神运动迟缓,肝脾肿大,骨改变和黄斑区域的樱桃红点。幼年型GM1神经节脂质病没有这些外部特征。在成人类型的行为问题,痴呆,锥体外系问题特别突出。作者提出的症状,临床过程和实验室结果的一岁男孩诊断为GM1神经节脂质病。他自出生起就出现皮疹,发育迟缓,体重逐渐减轻,反复腹泻6个月。

Background: Anaesthesia for herniotomy may be challenging because the margin of error in managing such a young patient can be extremely small since the body reserves are limited and the organ systems may not be fully developed. Also, the psychological, physiological and pharmacological responses to anaesthesia are quite different from adult. Safe and effective care of children under anaesthesia is therefore crucial. This study aims to audit the pattern of anaesthetisia techniques used and their associated complications during herniotomy procedure in our health facility. Material and methods: This is a retrospective review of patients’ files, theatre records and anaesthetic-record charts of herniotomy cases performed in a tertiary health Institution from January 2011 to December 2015. Relevant clinical information were entered into proforma designed for the study. Data was analysed with descriptive statistics using the Statistical Package for Social Sciences (SPSS) version 20 Chicago IL (U.S.A). Inferential statistics of Chi-Square, Mann-Whitney and Kruskal-Wallis Test were alsoperformed. Results: One hundred and fortyfour in-patient children who belonged to American Society of Anesthesiologists Physical Health Status (ASA) grade I and II had herniotomies during the study period. The mean age is 4.21±3.72years (range, 6months – 16years) with male to female ratio of 47:1 (i.e 141 to 3). General anaesthesia (135, 94%) of various techniques was the most common technique while regional anaesthesia was only employed in nine (6%) children. The regional anaesthesia techniques were caudal block 1 (0.7%) and subarachnoid block 8 (5.5%) and were sedated to allow for cooperation in some of the cases. One hundred and twenty-four (86%) children presented as simple, elective cases while twenty (14%) children as complicated or emergency cases. Conclusion: This study showed that herniotomy can be safely performed under various options of anaesthesia techniques depending on the expertise of the anaesthetists involved. The simple, electives inguinal hernia and hydroceles could have been performed as day cases.
背景:疝切开术的麻醉可能是具有挑战性的,因为管理这样一个年轻的病人的误差范围可能非常小,因为身体储备有限,器官系统可能没有完全发育。此外,对麻醉的心理、生理和药理反应与成人有很大的不同。因此,对处于麻醉状态的儿童进行安全有效的护理至关重要。本研究的目的是审核在我们的医疗机构疝气切开术中使用的麻醉技术及其相关并发症的模式。材料和方法:回顾性分析2011年1月至2015年12月在某三级医疗机构行疝切开术的患者档案、手术室记录和麻醉记录。将相关临床信息输入为研究设计的表格中。使用社会科学统计软件包(SPSS)版本20 Chicago IL(美国)对数据进行描述性统计分析。进行卡方检验、Mann-Whitney检验和Kruskal-Wallis检验的推论统计。结果:144名住院儿童在研究期间接受了疝切开术,他们属于美国麻醉医师协会身体健康状况(ASA) I级和II级。平均年龄为4.21±3.72岁(范围6个月- 16岁),男女比例为47:1(即141:3)。全麻是各种麻醉方法中最常见的麻醉方法(135,94%),而区域麻醉仅在9例(6%)患儿中使用。区域麻醉技术为尾侧阻滞1(0.7%)和蛛网膜下腔阻滞8(5.5%),并在某些情况下镇静以允许合作。124名(86%)儿童表现为简单的选择性病例,而20名(14%)儿童表现为复杂或紧急病例。结论:本研究表明,根据麻醉师的专业知识,疝切开术可以在各种麻醉技术下安全进行。单纯的、选择性的腹股沟疝和鞘膜积液可以作为日间病例进行。

Congenital chylous ascites (CCA) is a rare disease that results from the maldevelopment of the intra-abdominal lymphatic system. Due to the rarity of congenital chylous ascites and the lack of standards in diagnosis and therapy, this disease constitutes a medical challenge and individual therapy seems to be extremely important. A 3-month-old girl diagnosed with congenital chylous ascites. She was managed initially with nil per oral, parenteral nutrition, medium chain triglyceride (MCT) containing oil and abdominal paracentesis, followed by octreotide. Medium chain triglyceride formula, the main stay of management was discontinued with gradual reintroduction of breast feeds. This case was selected due to the rarity of CCA and the lack of standards in the diagnosis and therapy.

Histiocytoses are a rare group of proliferative disorders with very similar clinical and histological pictures. We present a case report of two variants seen in an eight-month-old female and five-month-old male in a tertiary hospital in southern Nigeria. They both presented with painless neck swellings and fever, leucocytosis, neutrophilia and lymphopenia. Initial histologic examinations of the cervical lymph nodes biopsy posed a diagnostic conundrum. However, Immuno-histochemical analysis done on both sample showed CD1a, positive S100 in keeping with Langerhans cell histiocytosis in the former. While, that of the latter showed strongly positive CD68, positive S-100 in 30% cells in keeping with Sinus histiocytosis with massive lymphadenopathy (SLMH) in the latter. Clinicians should have a high index of suspicion for histiocytosis in children presenting with generalised lymphadenopathy. Also, apart from the routine histology, immunohistochemistry analysis is recommended for all cases
组织细胞增多症是一种罕见的增殖性疾病,具有非常相似的临床和组织学表现。我们报告了尼日利亚南部一家三级医院一名8个月大的女婴和一名5个月大的男婴出现两种变异的病例报告。患者均表现为无痛性颈部肿胀、发热、白细胞增多、中性粒细胞增多和淋巴细胞减少。颈部淋巴结活检的初步组织学检查提出了一个诊断难题。然而,对两个样本进行的免疫组织化学分析显示CD1a, S100阳性,与前者的朗格汉斯细胞组织细胞增多症保持一致。而后者的CD68呈强阳性,S-100阳性的细胞占30%,与后者的窦性组织细胞增生伴大量淋巴结病(SLMH)一致。临床医生应该对全身性淋巴结病患儿的组织细胞增多症有高度的怀疑。此外,除常规组织学检查外,建议对所有病例进行免疫组织化学分析

Folic acid and brain function in childhood 叶酸与儿童大脑功能的关系
Pub Date : 2021-01-01 DOI: 10.4314/njp.v48i2.5
A. Asindi, Komomo Eyong
Folic acid supplementation does not only prevent neural tube defects in the foetus but is an essential ingredient in the growth and development of the cerebral cortex. This micronutrient promotes the thickness of the cerebral cortex; the extent of the thickness being directly proportional to the intelligent quotient, neurocognitive and psychological output of the child. Children with thin cortices are prone to poor cognitive performance, autism and psychiatric disorders such as depression. Folic acid supplementation in the first three months of pregnancy largely protects against neural tube defects; studies have shown that children whose mothers take folic acid supplement throughout pregnancy exhibit relatively higher levels of emotional intelligence. Nevertheless, in spite of long-standing recommendations that women of child-bearing age take folic acid to protect against neural impairment, a large proportion do not comply; less than half of the world’s population lives in countries that require folic acid fortification of grain products. A large portion of pregnant women in poor world countries do not attend antenatal care hence have no access to prescription of essential haematinic/folic acid. It is recommended that all women who are either planning or capable of pregnancy take a daily supplements containing 0.4 - 0.8 mg (400-800 μg) of folic acid. Fortified foods like some breads, juices, and cereals contain adequate folic acid; others are leafy green vegetables, like spinach, broccoli, and lettuce beans, peas, and lentils. Fruits like lemons, bananas, and melons are also rich sources of folate. There is need for more advocacy regarding antenatal care of pregnant mothers with emphasis on folate supplementation before and throughout pregnancy, to boost the intellectual and psychological capacity of children into adulthood.
补充叶酸不仅可以防止胎儿神经管缺陷,而且是大脑皮层生长发育的必要成分。这种微量营养素可以增加大脑皮层的厚度;厚度的大小与孩子的智商、神经认知和心理输出成正比。大脑皮层薄的儿童容易出现认知能力差、自闭症和抑郁症等精神疾病。在怀孕的前三个月补充叶酸在很大程度上防止神经管缺陷;研究表明,母亲在怀孕期间服用叶酸补充剂的孩子表现出相对较高的情商。然而,尽管长期以来一直建议育龄妇女服用叶酸以防止神经损伤,但很大一部分人不遵守;世界上不到一半的人口生活在需要在谷物产品中添加叶酸的国家。贫穷国家的很大一部分孕妇没有参加产前保健,因此无法获得必需的血红素/叶酸处方。建议所有计划怀孕或有能力怀孕的妇女每天服用含有0.4 - 0.8毫克(400-800 μg)叶酸的补充剂。强化食品如面包、果汁和谷物含有足够的叶酸;其他的是绿叶蔬菜,比如菠菜、西兰花、莴苣豆、豌豆和小扁豆。柠檬、香蕉和甜瓜等水果也富含叶酸。有必要对孕妇的产前护理进行更多的宣传,重点是在怀孕前和整个怀孕期间补充叶酸,以提高儿童成年后的智力和心理能力。

Background: Caregiver delay in presentation has been cited as a major contributor to poor prognosis of paediatric cancers in low-middle income countries like Nigeria. This study explored the time duration between onset of symptoms and presentation to healthcare facilities, diagnosis, and referral for specialist care. Methods: Data were compiled from caregivers of newly registered children at a teaching hospital in Nigeria. Sociodemographic and clinical history of the child were taken. Type of cancer, date of diagnosis, centre where the diagnosis was made, treatment start date, and duration of symptoms until treatment were elicited from consenting caregivers and documented. Results: Acute lymphoblastic leukaemia was the most prevalent cancer type among the patients. The mean time from first symptom to presentation was 15 weeks and from presentation at any health care facility to specialist referral and diagnosis was 38 and 39 weeks, respectively. Time from diagnosis to treatment was a mean of 8 weeks (range: 1 to 27 weeks) Conclusion: Delayed presentation has become a commonly cited factor for poor cancer outcomes in Nigeria and may often inaccurately assign blame to the patient/caregivers. The results of this study point to delayed detection, delayed diagnosis and delayed referral for specialist care, as more accurate contributors to late-stage presentation and consequently worse outcomes of paediatric cancers in Nigeria. Strengthening of community and primary level healthcare professionals’ understanding of paediatric cancers, establishment of simple detection algorithms and national implementation of efficient referral protocols will potentially reduce delays in specialist attention and improve outcomes.
背景:在尼日利亚等中低收入国家,护理人员延迟就诊被认为是导致儿童癌症预后不良的主要原因。本研究探讨了从症状发作到到医疗机构就诊、诊断和转诊到专科护理之间的时间间隔。方法:从尼日利亚一家教学医院新登记儿童的护理人员中收集数据。采集儿童的社会人口学和临床病史。癌症类型、诊断日期、诊断中心、开始治疗日期和症状持续时间,直到治疗从同意的照顾者那里得到并记录下来。结果:急性淋巴细胞白血病是患者中最常见的癌症类型。从首次出现症状到出现症状的平均时间为15周,从出现在任何卫生保健机构到专家转诊和诊断的平均时间分别为38周和39周。从诊断到治疗的平均时间为8周(范围:1至27周)结论:在尼日利亚,延迟出现已成为导致癌症预后不良的一个常见因素,并且可能经常错误地将责任归咎于患者/护理人员。这项研究的结果指出,延迟发现、延迟诊断和延迟转诊到专科护理是尼日利亚儿童癌症晚期出现并因此导致更糟糕结局的更准确因素。加强社区和初级保健专业人员对儿科癌症的了解,建立简单的检测算法,并在全国实施有效的转诊协议,将有可能减少专科治疗的延误,并改善结果。

Background: Newborn morbidity and mortality have remained unacceptably high in developing countries despite consistent efforts at controlling  the scourge. Unlike in developed countries where neonatal mortality rate ranges between 1 and 5 per 1000 live births, average neonatal mortality rate in Nigeria is 36 per 1000 live births. The majority of the causes of death are largely preventable with timely low cost interventions. This study was structured to determine the pattern of morbidity and mortality amongst babies admitted in the Special Care Baby Unit of Madonna hospital Makurdi, Nigeria.Methods: The records of neonates admitted into the Special Care Baby Unit (SCBU) over a tenyear period (2005-2015) were retrospectively reviewed. Information obtained included the sex, age at admission, gestational age, birth weight, reasons for admission and outcome of treatment.Results: A total of 1,121 babies were admitted during the period under review. The male female ratio was 1.2:1.The majority of the babies were aged between 2-7 days with a mean 6.17.+ 7.01 The mean weight on admission was 2807+907g. Neonatal sepsis, jaundice, low birth weight and birthasphyxia were the most common morbidities. The overall mortalityrate was 14.1%; however, proportionate mortality due to low birth weight was highest (26.4%), followed by tetanus (23.5%), asphyxia (20.8%), Respiratory tract infection (13.8%), meningitis (13.3%), sepsis (10.3%), jaundice (9.6%), and diarhoea (4.0%)Conclusion: Neonatal mortality rate in the study was high. The major causes of admission are preventable. Strengthening perinatal care, emergency obstetric care services and neonatal resuscitation skills are necessary to reduce the neonatal mortality.

Background: Rapid diagnostic test (mRDT) is a useful tool in demonstrating parasitologically proven malaria. Its efficacy is however hampered  when parasite density is low. Prophylactic use of cotrimoxazoleas in cases of HIV infected children can cause reduction in parasite count. It is  doubtful if mRDT will retain its diagnostic usefulness among such individuals.Objectives: The study sought to evaluate the diagnostic value of mRDT in HIV infected children on cotrimoxazole prophylaxis in Benin City.Methods: In the prospective, cross sectional and descriptive study, we assessed malaria parasitaemia using standard methods in microscopy and parasite density and malaria antigenaemia using Care Start Pf (monoclonal antibodies specific to histidine rich protein – 2 antigen) in 221 each of HIV infected subjects on cotrimoxazole managed in a specialist clinic and HIV negative controls all seen at the University of Benin Teaching Hospital between April and June 2016.Results: Malaria antigenaemia rate MAr (20.8%) was lower than malaria parasitaemia rate MPr (24.4%) in subjects. MAr (20.8) and MPr (24.4%) in  subjects were higher than MAr (18.10%) and MPr (17.7%) in controls. Mean (SEM) parasite count in subjects of was low (50.88 + 2.24 per μl). Using microscopy as gold standard the sensitivity, specificity, PPV and NPV of mRDT in subjects were 77.8%, 97.6%, 91.3% and 93.1%. Corresponding values in controls were 100.0%, 99.5%, 97.5% and 100.0%.Youden indices for subjects and controls were 0.75 and 0.99.Conclusions/Recommendations: Sensitivity of mRDT in HIV infected children on cotrimoxazole prophylaxis for opportunistic infections (OI) is reduced. However the indices of specificity, PPV and NPV are high enough to retain its value in the evaluation of HIV infected children for  asymptomatic malaria and perhaps the clinical disease.

背景:快速诊断试验(mRDT)是一种有用的工具,可用于诊断寄生虫学证实的疟疾。然而,当寄生虫密度较低时,其效果受到阻碍。感染艾滋病毒的儿童预防性使用复方新恶唑可导致寄生虫数量减少。mRDT是否会在这些个体中保留其诊断效用是值得怀疑的。目的:评价mRDT对贝宁市HIV感染儿童复方新诺明预防的诊断价值。方法:在前瞻性、横断性和描述性研究中,我们使用显微镜标准方法评估疟疾寄生虫血症和寄生虫密度,并使用Care Start Pf(富组氨酸蛋白- 2抗原特异性单克隆抗体)评估疟疾抗原血症,在2016年4月至6月期间在贝宁大学教学医院接受复方新诺明治疗的221名HIV感染者和HIV阴性对照。结果:调查对象疟疾抗原血症发生率MAr(20.8%)低于疟原虫血症发生率MPr(24.4%)。受试者的MAr(20.8)和MPr(24.4%)高于对照组的MAr(18.10%)和MPr(17.7%)。被试的平均(SEM)寄生虫数较低(50.88±2.24 / μl)。以显微镜为金标准,mRDT在受试者中的灵敏度、特异性、PPV和NPV分别为77.8%、97.6%、91.3%和93.1%。对照组对应值分别为100.0%、99.5%、97.5%和100.0%。受试者和对照组的约登指数分别为0.75和0.99。结论/建议:HIV感染儿童对复方新诺明预防机会性感染(OI)的mRDT敏感性降低。但特异性、PPV和NPV指标较高,在评估HIV感染儿童无症状疟疾和可能的临床疾病时仍有其价值。关键词:mRDT,效用,hiv感染儿童,复方新恶唑预防,贝宁市
