Clinical findings and surgical outcomes of encephalocoeles
Background: Encephalocoeles are herniation of the brain and its meninges via a midline cranial vault defect or at the base of the skull, at the site of local mesenchymal disruption. It accounts for 10% to 20% of all the cranial and spinal dysraphisms found in 1/5000 live births.Method: It is a 5 year retrospective study on 42 cases of encephalocoele managed in a Nigerian Tertiary Medical Centre. We extracted the clinical findings and surgical management outcomes from the patient's case notes.Result: Ages at presentation were Neonates (24, 57.1%), ≤3 months (35, 83.3%), with mode of 2 days. Males (12, 28.6%), females (30, 71.4%), with M:F=1:2.5. Posterior (occipital) lesions (36, 85.7%), anterior (6, 14.3%). Variable size lesions (33, 78.6%), giant encephalocoeles (9, 21.4%). Hydrocephalus (16, 38.1%) included pre-excision HCP (12, 75% of 16) and post excision HCP (4, 25% of 16). Available neuroimaging was TFUSS (all, 100%), CT Scan (20, 47.6%), MRI (2, 4.8%). Surgery of excision and repair (36, 85.7%), combined craniofacial repair (6, 14.3%), additional ventriculoperitoneal shunt (16, 38.1%). Post-operative complications included CSF leak (2, 4.8%), superficial surgical site infection (3, 7.1%), meningitis (1, 2.4%), shunt infection (4, 9.5%), shunt obstruction (7, 16.7%). Outcomes were good (38, 90.5%), blind (3, 7.1%), vegetative (1, 2.4%), death (1, 2.4%).Conclusions: Encephalocoeles are an uncommon congenital type of neural tube defect containing herniated brain tissue. Posterior (occipital) lesions are commoner (and maybe of giant size) than anterior lesions (Sincipital). Surgical outcomes are generally good

An Empirical Study on the Use Intention of Electronic Cash Collection System in Nigerian Federal Hospitals
It is a well-known fact that the use of electronic systems around the globe has facilitated and enhanced the efficiency in organizations. In light of this, federal hospitals in Nigeria have started using electronic collection system for cash collection purposes. Electronic cash collection system (e-collection) is a computerized system designed to handle cash collections with a view to block revenue leakages that are widespread within the Nigerian public sector organizations. However, the continuous use of the system is being faced with great resistance by those employees that were purposely meant to use it. In view of that, the aim of this paper is to investigate factors that could influence employee’s intention to use e-collection system in the performance of their duties. Technology Acceptance Model (TAM) was adapted with an extension of computer self-efficacy variable with a view to providing additional explanation to the model. Partial Least Square (PLS) was used to analyse 116 responses from e-collection users in investigating the relationship between three independent variables (perceived usefulness, perceived ease of use, computer self-efficacy) and the dependent variable (intention). The results of the analysis revealed that positive and significant relationships exist between the independent variables and the dependent variable except between perceived usefulness and intention. Recommendations were made to the hospital authorities to educate and enlighten the concern employees on the usefulness and benefits of the new system

A HINDU-ARABIC TO HAUSA NUMBER TRANSCRIPTION SYSTEM
The invention of the numeration system is regarded as one of man's great accomplishments. It
greatly helps man express his communication needs and serves as an important tool in
language pedagogy, historical linguistics, comparative study of African languages, and
computational linguistics. However, the numeral system is reported to be an endangered area
being identified in the use and study of language, and in no distant time, the traditional number
system of the African indigenous counting systems may lose its contact with the new generation.
This paper presents a Hindu-Arabic to Hausa number transcription system. Secondary data
used was sourced from literature. Context-Free Grammar (CFG) and Unified Modelling
Language (UML) was used to design the system. The system designed was implemented using
the Python programming language. Mean Opinion Score (MOS) evaluation approach was used
to evaluate the implemented system. The result of the evaluation on Numbers with Single
Representations (NSR), and Numbers with Multiple Representations (NMR) is based on three
(3) metrics: syllable accuracy, orthography accuracy and syntax accuracy. The experimental
respondents', system developed, and human expert average scores on NSR were respectively
0%, 100% and 100% for syllable accuracy, 40.1%, 100% and 100% for orthography accuracy,
and 62.8%, 100% and 100% for syntax accuracy. Similarly, the experimental respondents',
system developed, and human expert average scores on NMR were respectively 0%, 100% and
100% for syllable accuracy, 21.4%, 100% and 100% for orthography accuracy, and 31.7%,
100% and 100% for syntax accuracy. The system is capable of transcribing cardinal numbers,
1 to 1-billion, and the expert response confirmed its accuracy. The study concluded that among
others, the developed system is of great importance in the teaching and learning of the
traditional Hausa counting system. Future work on contextual Hausa numeral system analysis
is recommended
Penetrating abdominal injuries in children: a study of 33 cases
Background: Trauma is gradually becoming a major cause of disability and it can be of any form, physical or emotional. For the surgeon the physical form is of major interest, especially its causes and incidence, which can be influenced by environmental or social factors.Aim: The aim of this work was to study the incidence, etiology, principles of management and outcome of children with penetrating abdominal injuries.Materials and methods: This was a 2-year prospective study of 33 children aged 0–15 years with penetrating abdominal injuries at the University of Maiduguri Teaching Hospital in northeast Nigeria. Information obtained included the following: the patient’s biodata, mechanism of injury, time of presentation to the Accident and Emergency Department after the injury, haemodynamic status at presentation, presence or absence of abdominal organ evisceration, presence or absence of associated injuries, the timing of surgery, intraoperative findings, the type of surgical procedure and outcome.Results: Thirty-three (31.4%) children [of whom 24 (i.e. 72.7%) were from the rural areas] of 105 children with trauma-related injuries had penetrating abdominal injuries. The male : female ratio was 3 : 1, and the mean age ± SD was 2.30± 0.81 years. There were 15 (45.4%) children with gunshot wounds, 11 (33.3%) with bomb blast wounds, three (9.1%) with impalement injuries and two (6.1%) with arrow injuries. Fourteen (42.4%) patients had abdominal organ evisceration; of them, nine were as a result of gunshot injuries. Routine exploratory laparotomy was carried out in all 33 patients. Seven (21.2%) were operated on with simultaneous resuscitation in the immediate laparotomy group, and 26 (78.8%) underwent delayed laparotomy. There was a negative laparotomy in four (12.1%) patients, two of whom had only omental evisceration with no other accompanying visceral injuries, and two without evisceration. Three (9.1%) patients died after developing enterocutaneous fistula, compartment syndrome and sepsis.Conclusion: There were more cases of penetrating abdominal injuries among boys and children from the rural areas than in those from urban areas.Keywords: evisceration, exploratory laparotomy, penetrating abdominal injur
Assessment of Nutritional Status, Care and Support among Type 2 Diabetic Outpatients in Selected Hospitals within Kaduna Metropolis, Nigeria
Diabetes mellitus is a significant public health concern and a worldwide health hazard, with scientific research suggesting that an individual's nutritional status plays a role in its development. The presence of familial support has been found to be linked with enhanced coping mechanisms, higher quality of life, improved management of diabetes, and better overall health outcomes, which includes the prevention of complications. The present study aimed to evaluate the nutritional status, care, and support provided to outpatients with type 2 diabetes in specific hospitals located within the Kaduna Metropolis. The study employed a descriptive cross-sectional design, encompassing a sample size of 280 individuals diagnosed with diabetes. The Mini Nutritional Assessment (MNA) tool was utilised to collect data pertaining to socio-demographic characteristics, dietary patterns, health-related complications, and lifestyle patterns. The researchers collected anthropometric measurements, including weight (in kilograms) and height (in meters). They then calculated the body mass index (BMI) by dividing the weight by the square of the height (in kilograms per square meters). The nutritional status indices were classified according to the standards set by the World Health Organisation (WHO). The data were subjected to analysis using the Statistical Package for the Social Sciences (SPSS), with a predetermined level of significance set at P<0.05. The results indicate that a majority of the participants, specifically 69.64%, reported consuming fruits on a daily basis, while 32.14% reported consuming vegetables daily. The near half of participants (50.71%) exhibited normal weight, while 13.92% were classified as underweight, 19.64% as overweight, and 15.71% as obese. The primary complication encountered by the respondents was hypertension, with a prevalence rate of 36.07%. The research findings indicated a significant prevalence of familial and partner involvement in the care and support of individuals diagnosed with diabetes mellitus. The study demonstrated a statistically significant association (p<0.05) between nutritional status and various factors, including occupation, religion, age, education, marital status, and monthly income. It is advisable to implement screening protocols for diabetic complications as a means of mitigating the risk of malnutrition among individuals with diabetes. Further investigation is warranted to explore the efficacy and obstacles associated with familial and partner assistance for individuals receiving medical care
