This study analyzes the sensitivity analysis using shadow price of plastic products. This is based on a research carried out to study optimization problem of BOPLAS, a plastic industry in Maiduguri, North eastern Nigeria. Simplex method of Linear programming is employed to formulate the equations which were solved by using costenbol software. Sensitivity analysis using shadow price reveals that the price of wash hand bowls is critical to the net benefit (profit) of the company.

Background: Depression is the most prevalent psychiatric disorder in pregnancy and it is associated with psychosocial and obstetric factors. Studies have shown that pregnancy does not prevent women from becoming depressed;rather, it may be a time when depression occurs for the first time in some women. Antenatal depression has been identified as a risk factor for post natal depression, adverse obstetric outcomes, poorer neonatal outcomes and higher growth retardation in infants. Purpose: This study aimed to determine the fetal growth outcomes among depressed pregnant women in their third trimester attending antenatal clinic at the Jos University Teaching Hospital (JUTH), Jos, Plateau State, Nigeria. Method: A prospective cohort study design was used to assess 514 women who consented to the study (256 cases and 258 controls). A socio-demographic questionnaire was given to the women to fill out the study entry. Edinburgh Post Natal Depression Scale (EPDS) was used to screen for depression and MINI neuropsychiatric interviews were used to diagnose depression in those women found to be at risk of depression using the EPDS. Ultrasonography was used to determine the fetal weight in the third trimester of pregnancy. The birth weight of the babies born to the women was obtained from the birth register in the labor ward and the fetal growth rate was calculated from the estimated fetal weight on ultrasound scan in late pregnancy and the birth weight of babies. Result: The mean fetal weight in the third trimester for non-depressed women was slightly higher than in depressed women though the difference was not statistically significant (P = 0.431). The difference in the mean calculated fetal growth rate for fetuses of non-depressed women in the third trimester was statistically significantly higher than in depressed women (p = 0.000). Depressed women also had babies with lower birth weight than non-depressed women and the difference was statistically significant (p = 0.00).

Quality of life (QoL) is becoming a widely accepted schizophrenia management outcome. But it is still not very clear if there are any significant differences between the conventional and atypical antipsychotics in terms of QoL improvement among people with schizophrenia (PWS). It is also imperative that antipsychotic drug-related factors, such as medication adherence and side-effect, which could directly or indirectly affect the QoL of PWS, are determined and compared among PWS on different classes of the drugs. Data were collected on Socio-demographic Characteristics, Quality of Life and Medication adherence using Socio-demographic and Schizophrenia Clinical Characteristics questionnaire, World Health Organization Quality of Life (WHOQoL)-Brief, and Morisky Medication Adherence Scale (MMAS) respectively from 250 respondents attending a tertiary health center’s Psychiatric clinic in Kano, Nigeria. Although PWS on the two classes of antipsychotic drugs showed inequalities in different aspects and domains of QoL, as well as in the levels of adherence and side-effects, the differences were all insignificant. However, presence of drug side effects was significantly associated with lower health-related QoL in the conventional antipsychotics group (p = 0.001), and lower score in the physical domain of QoL in the atypical antipsychotics group (p = 0.044). Medication adherence was found to be associated with better scores in different domains of QoL in both groups of PWS. There are no significant differences in terms of QoL, medication side-effect and adherence among PWS on the two classes of antipsychotics. However, drug side-effects and adherence were significantly and respectively associated with lower and higher scores in different domains of QoL in both groups.

Depressive disorder is a major contributor to years lived with disability (YLD) globally. It is estimated that 13% of all women experience the disorder in the first year postpartum. Postpartum depression (PPD) has significant implications to the physical and mental wellbeing of both the mother and her baby. Only non-depressed pregnant women (score of ≤ 6 on Edinburgh Postnatal Depression Scale) were recruited into this study. Data collection was done at 2 different stages;at recruitment stage (during the third trimester of pregnancy) and at the follow up stage (4th - 6th week postpartum). During the recruitment stage, intimate partner violence (IPV) and level of social support perception, among the women, were assessed using Hurt Insult Threaten Scream (HITS) and Multidimensional Scale of Perceived Social Support (MSPSS) questionnaires respectively. While at the follow up stage, the Obstetric questionnaire and Mini International Neuropsychiatric Interview (MINI-7) were used respectively to obtain obstetric-related data and to diagnose for occurrence of depression. The incidence of PPD was found to be 16.34%. Several factors such as level of education, husband’s socioeconomic status, stressful life events, low perception of social support, obstetric instrumentation and not having a baby of preferred gender were significantly associated with PPD. Positive predictors of PPD included not practicing breast feeding (OR = 186.72, 95% CI = 8.32 - 4188.35), family history of mental illness (OR = 4.95, 95% CI = 1.04 - 23.81) and pregnancy lasting beyond 40 weeks (OR = 7.26, 95% CI = 1.51 - 34.88). High incidence of PPD with numerous associated but largely modifiable risk factors call for more proactive measures, such as PPD screening among pregnant women.

Background: Ethmoidal polyposis coexisting with adenoid enlargement and tympanic membrane perforation is a rare condition in otolaryngological practice. Evidences have shown that antrochoanal polyp often times coexists with adenoid enlargement especially in the young which was in sharp contrast to ethmoidal polyposis occurring in the presence of adenoid enlargement. Moreover, the hidden location of nasopharynx housing the adenoids, coupled with the masking effect of bilateral sinonasal polyps, leads to inadvertent misdiagnosis of this complex pathology with subsequent difficulty in providing effective management. Case Presentation: A 24 year-old lady presented with recurrent bilateral nasal obstruction that became persistent associated with nasal discharge and anosmia. She also had recurrent right otorrhoea with associated hearing loss. Diagnostic rigid nasal endoscopy revealed mucoid discharge with bilateral polypoid masses filling both nasal cavities. Otoendoscopic finding revealed a small (about 5%) central tympanic membrane perforation. A clinical assessment of chronic rhinosinusitis with nasal polyposis complicated by chronic suppurative otitis media (CSOM) was made. A non-contrast CT scan of the paranasal sinuses showed isodense lesions in the nasal cavities, all paranasal sinuses and the entire nasopharynx. She had endoscopic sinus surgery and a nasopharyngeal clearance biopsy. The nasal, paranasal and nasopharyngeal masses had histologic confirmation of inflammatory nasal polyps and lymphoid (adenoid) hyperplasia respectively. Her condition improved remarkably with subsequent medical treatment. She was followed up for 8 months and no recurrence was observed. Conclusion: Sinonasal polyposis can coexist with adenoid hypertrophy and middle ear disease as a single pathological condition. Hence, a high index of suspicion and thorough evaluation become necessary for making timely diagnoses and instituting effective management.
