Nigerian Journal of Clinical Practice 2019 22(6):745-749

Background: Screening for cervical cancer improves outcome. This comes at an economic price which some may not be able to afford. Objective: To evaluate the influence of user fees on the utilization of cervical cancer screening services in Port Harcourt. Materials and Methods: A cross sectional study of clients presenting for cervical cancer screening. Data on the number, socio-demographic characteristics, distance from screening center following 1 month of free cancer screening and 7 months of user fee introduction, was collated and analyzed using SPSS version 20 statistical software. Results are presented in percentages, tables and charts with test of significance set at P < 0.05. Results: Of the 167 women who presented for cervical cancer screening during the study period, the mean age was 42.08 ± 8.9 years and range was 20–70 years. The average parity of patients was 2.83 ± 2.24. Clients' utilization of cervical cancer screening facilities was negatively affected by the introduction of user fees P < 0.001). There is no association between the distance of patients' home from the hospital and the utilization of facility (X2 = 0.24, P = 0.887). There was sustained decrease in number of clients with the introduction of fees. Conclusion: The introduction of user fees had a negative impact on the utilization of cervical cancer screening facilities. Eradicating user fee and improving the socioeconomic status of patients may improve the utilization of screening services.

J Wang, S Ye

Nigerian Journal of Clinical Practice 2019 22(6):750-753

Objective: To study the role of hypoxia inducible factor-1α (HIF-1α) in patients with diabetic nephropathy (DN). Methods: In total, 133 participants were selected to conduct the investigation, parameters such as fasting blood sugar (FBS), blood urea nitrogen (BUN), and urine albumin-creatinine ratio (UACR) were tested and recorded. The biopsy assessment was conducted when renal function or urinary abnormalities. Western blotting was used to test the expression of serum HIF-1α in all patients and control group. Results: The values of FBS, BUN, and UACR were higher in DN and diabetes groups than in the healthy control. The values of FBG, BUN, and UACR were higher in DN patients than in the diabetes patients with no nephropathy. eGFR in DN patients was lower than the other two groups. The expression of HIF-1α was higher than both diabetes patients with no nephropathy and healthy control, P < 0.05. Patients with lots of albuminuria showed the highest expression of HIF-1α than the other groups. HIF-1α in normoalbuminuria and microalbuminuria groups showed no significant difference. Conclusions: HIF-1α was up-regulated in DN patients, which might give clinical basis to the role of HIF-1α in the development of DN.

C Koca, N Komerik, O Ozmen

Nigerian Journal of Clinical Practice 2019 22(6):754-762

Background: Reconstruction of bone defects in oral and maxillofacial surgery has widespread uses. In recent years, the capacity of various biomaterials alone or in combination with bone graft materials to increase bone healing has been an intensive research topic. The aim of this study is to evaluate the efficacy of hyaluronic acid and/or bone graft material on bone healing in defects created in the rat mandible. Methods: In our study, rats were divided into 4 groups. Group 1 is designated to be treated with no materials, Group 2 with graft material, Group 3 with only hyaluronic acid, and Group with hyaluronic acid and graft material. A critical-size defect of 5 mm in diameter was created bilaterally in the rat mandibles and the rats were divided into the indicated groups accordingly. At the end of the postoperative 6th week, the experiment was terminated. The right halves of the mandibles were evaluated immunohistochemically and histopathologically in terms of bone healing, and the left in terms of mineralization level via microcomputed tomography. Results: Histopathological evaluation showed that healing in the empty group was significantly lower than the other groups that were treated with materials (P < 0.05); but the difference between the material-treated groups was not significant. Immunohistochemical evaluation revealed that the staining was moderately positive/strongly positive in all groups, but the difference between the groups was not significant. The highest mineralization values observed in the defected areas that belonged to 2 groups using hyaluronic acid, and the difference between them was found to be statistically significant (P < 0.05). The lowest mineralization values observed in the defected areas was most frequent in the group where only the hyaluronic acid was used, and there was a statistically significant difference between the other groups (P < 0.05). Conclusion: In conclusion, the use of hyaluronic acid alone or in combination with bone grafting has been shown to contribute positively to the improvement of bone defects in the jaw area.

U Koc Vural, S Gurgan

Nigerian Journal of Clinical Practice 2019 22(6):763-770

Background: Repair of a failed amalgam or composite resin (CR) restoration has been extremely studied and proposed as a routine clinical treatment option; however, repair potential of glass ionomer-based restorative materials was not studied sufficiently in the literature. Aim: The aim of this study is to evaluate the repair potential of a glass hybrid (GH) restorative repaired either by the same material (GH) or CR after different surface treatments using microtensile bond strength (μTBS) test. Methods and Materials: One hundred and twenty bar-shaped (2 × 2 × 8 mm) GH blocks were prepared. After aging, the specimens were divided into two groups (n = 60) and five subgroups (n = 12). The specimens in Group I were repaired with the following protocols: (a) no treatment + GH, (b) diamond bur (B) + GH, (c) cavity conditioner + GH, (d) cavity conditioner + universal adhesive (A) + GH, (e) A + GH, and specimens in Group II were repaired with (a) no treatment + CR, (b) B + CR, (c) B + A + CR, (d) 40% phosphoric acid + A + CR, (e) A + CR. The specimens that were subjected to μTBS testing, scanning electron microscopy evaluations, and fracture modes were determined. Data were analyzed using Kruskal–Wallis and Mann–Whitney U tests (P = 0.05). Results: Repair using CR resulted in higher bond strengths (P < 0.001). The lowest bond strength was obtained in Group Ie. The highest bond strength was obtained when GH was roughened in Group IIc. Conclusion: Repair of restorative GH with CR appears as a preferred option to improve the bond strength.

HT Alkis, OM Bilge

Nigerian Journal of Clinical Practice 2019 22(6):771-776

Objectives: The aim of this study was to evaluate the effect of different occlusion types on mandibular asymmetry in different anatomical points using posteroanterior cephalometric radiography. Materials and Methods: This study was retrospectively conducted on 100 patients whose posteroanterior images and malocclusions were registered in a patient database. Asymmetry indices were determined using four linear measurements on images, and the effect of malocclusions, age, and gender on these asymmetry indices was investigated. P <0.05 was considered statistically significant. Results: Right and left horizontal plane gonion distance values varied according to gender, right vertical plane condylar distance and left horizontal plane gonion distance values varied according to age, and right vertical plane condylar distance and left horizontal plane gonion distance values varied according to malocclusions. Conclusion: The measured values of some parameters varied according to age, gender, and malocclusion. Although vertical plane gonion asymmetry index and horizontal plane condylar asymmetry index values varied according to gender, there was no relationship between asymmetry index values of all parameters with age and malocclusion.

H Kafadar, S Kafadar

Nigerian Journal of Clinical Practice 2019 22(6):777-781

Background: Sharp and penetrating object injuries (SPOIs) are seen frequently in forensic medicine practice. In this study, we aimed to retrospectively investigate cases with SPOIs. Materials and Methods: This study investigated the charts of patients treated at Adiyaman University Education and Research Hospital between January 1, 2013, and December 31, 2017. A total of 934 inpatients with sharp object injuries were included in the study. Data were assessed using a suitable computer-aided package program. Cases were examined in terms of age, gender, injury body site, suicide or homicide, radiologic findings, presence of vital danger, and severity of injury. Results: In this study, we examined the charts for 934 inpatients with stab wounds. It was stated that 124 (13.27%) of those injured were female and 810 (86.63%) male; the average age of the injured persons was 29.8 ± 18.2 years. It was found that 214 (22.91%) people were exposed to vital danger and that 720 (77.09%) suffered from soft tissue injuries (penetrating skin and muscle injuries). Also, 69.27% of the cases (n = 647) involved people less than 35 years of age. Conclusion: Considering that stab injuries are more frequent in the lower age groups, we believe that such injuries could be reduced by increasing training programs for young people.

FD Oz, N Attar, D Deniz Sungur

Nigerian Journal of Clinical Practice 2019 22(6):782-789

Objective: The aim of this in vitro study was to investigate the fracture strength and cuspal deflection of endodontically treated premolars restored using different composite resins along with or without fiber post application. Materials and Method: Eighty intact premolars were randomly divided into eight groups (n = 10); CO group: intact teeth (control), OPR group: mesio-occlusal-distal-palatal (MODP) preparation (OPR) + endodontic treatment (ET), TC group: MODP preparation + ET + Tetric N-Ceram, TB group: MODP preparation + ET + Tetric EvoCeram Bulk Fill, SO group: MODP preparation + ET + SonicFill 2, TC-P group: MODP preparation + ET + Hahnenkratt glass fiber post + Tetric N-Ceram, TB-P group: MODP preparation + ET + Hahnenkratt glass fiber + Tetric EvoCeram Bulk Fill, and SO-P Group: MODP preparation + ET + Hahnenkratt glass fiber post + SonicFill 2. After thermocycling, specimens were subjected to a compressive load until fracture. Data were analyzed using analysis of variance and Tukey tests (P < 0.05). Results: The mean fracture strength of groups which received post treatment showed similar fracture strength values [TC-P (931.6 ± 97.9), TB-P (882.0 ± 59.7), SO-P (862.0 ± 143.0) (P > 0.05)] and was significantly higher than OPR (530.6 ± 41.7), TC (841.2 ± 93.1), TB (774.5 ± 101.8), and SO (735.0 ± 178.01) groups (P < 0.05). No significant difference was detected among groups considering cuspal deflection (P > 0.05). The fiber post insertion resulted in more unfavorable fractures. Conclusion: Endodontically treated teeth restored with fiber post and bulk-fill or conventional composite resins demonstrated fracture strength values similar to intact teeth.

AO Asinobi, AD Ademola, OO Ogunkunle

Nigerian Journal of Clinical Practice 2019 22(6):790-795

Background: Earlier studies on childhood nephrotic syndrome (NS) in tropical Africa showed steroid resistance in the majority. More recent studies show a variable picture, necessitating a re-evaluation. This study was aimed at determining the current pattern of steroid response in childhood NS, in an environment known to be dominated by steroid resistance. Patients and Methods: This prospective study of consecutive children who received steroid therapy for primary NS was carried out at the University College Hospital, Ibadan, Nigeria between 2006 and 2013. The outcomes of interest were steroid sensitivity and death. The recruited patients received a 4-6 weeks' course of prednisolone at 60 mg/m2/day followed by alternate day doses of 40 mg/m2 up to total steroid therapy duration of 6 months in steroid sensitive patients. Statistical analysis was carried out using STATA version 12.0. P value <0.05 was considered significant. Results: Of 109 children that received steroids for at least 8 weeks, whose mean (SD) age was 7.9 (3.7) years, 69 (63.3%) were steroid sensitive. Those aged ≥6 years responded as well as those aged <6 years (P = 0.78). Boys were more likely to be steroid-sensitive than girls, 65.2% versus 34.8% (P = 0.039). There was zero mortality among the patients studied. Conclusion: This study has shown a better steroid sensitivity of 63.3% in children with primary NS compared with the previously reported 36.8-42.9% in patients with highly selective proteinuria. This improved steroid response and zero mortality show a remarkable departure from the past.

AO Akinbade, KC Ndukwe, FJ Owotade

Nigerian Journal of Clinical Practice 2019 22(6):796-800

Background: The choice of an efficacious and well-tolerated analgesic for the control of postoperative pain after third molar surgical extraction remains a challenge. Aim: The aim of this study was to compare analgesic efficacy and tolerability of celecoxib and tramadol following mandibular third molar extraction. Materials and Methods: This was a prospective randomized, double blind controlled trial. Ninety patients were randomly assigned equally to either celecoxib or tramadol. Appropriate doses of the assigned drugs were administered orally immediately after the surgical extraction and patients recorded the pain intensity felt before the extraction, immediately after extraction, at 4 h, 8 h, 16 h, 24 h, and 48 h after the extraction using the visual analogue scale (VAS). Adverse effects of the medications were also recorded. Results: Four of the patients dropped out of the study. Fifty five percent of patients in tramadol group experienced adverse effects but none in celecoxib group. The median VAS score of the celecoxib group was lower than tramadol group throughout the postoperative period and there was statistically significant difference in the median VAS score between the two groups 4 hours after drug administration (P = 0.001). Conclusion: In our study, celecoxib was more efficacious and better tolerated than tramadol for the management of pain after surgical extraction of mandibular third molar.

P Onal, N Oztas, G Kip

Nigerian Journal of Clinical Practice 2019 22(6):801-805

Background: Patients with cerebral palsy (CP) are at significant risk by means of periodontal disease and tooth decay. Pharmacological techniques that require intensive care such as sedation and general anesthesia are generally used for dental treatment of this patient group. Aim: The purpose of this retrospective study was to compare bispectral index (BIS) values and depth of sedation recorded during deep sedation protocols performed for healthy children and children with CP in the Department of Pediatric Dentistry, Faculty of Dentistry, Gazi University. Materials and Methods: The measurements of BIS and hemodynamic variables recorded during treatment of 26 healthy children and 26 children with CP between 3 and 10 years of age who were treated under sevoflurane and 50% N2O–50% O2 mixture deep sedation method were investigated retrospectively. Results: The mean BIS values in the CP group was statistically lower at all the time points when compared with the control group (P < 0.001). While there was no statistically significant difference between groups in terms of duration of treatment (P = 0.657), the median recovery time in the CP group was significantly longer than that recorded in the control group (P < 0.001). Significant correlation was found between modified Ramsay Sedation Scale (mRSS) scores and BIS levels at 5th, 10th, and 20th min in the control group (P < 0.001). Similar correlation was found in the CP group at 15th and 20th min. Conclusion: We concluded that it is necessary to consider the dosage and effect mechanisms of drugs used in children with CP to prevent overuse of anesthetics and emergence of anesthesia-related complications.
