p. 289
Q Liu, J Cao, JJ Kong
DOI
:10.4103/njcp.njcp_8_18
PMID
:30837413
Objective:
This study aims to discuss the clinical effect of balloon kyphoplasty on elderly patients with multiple osteoporotic vertebral fractures.
Methods:
The observation group was treated with balloon kyphoplasty, and the control group was managed with conservative treatment. Image indices, pain degree, daily life disturbance, and occurrences of complications were compared between the two groups.
Results:
In total, 116 elderly patients with multiple osteoporotic vertebral fracture admitted in our hospital from January 2016 to June 2017 were chosen and divided randomly into observation (
n
= 58) and control groups (
n
= 58). The observation group showed a significantly higher trailing edge, leading edge, and midcourt line and larger upper thoracic kyphosis compared with the control group (
P
< 0.05). Before the treatment, no statistically significant differences were observed between the two groups in terms of visual analog scale (VAS) score and daily life disturbance score (
P
> 0.05). However, the VAS score and the daily life disturbance score of the two groups decreased sharply after the treatment (
P
< 0.05). Moreover, the VAS score and the daily life disturbance score of the observation group were significantly lower than those of the control group (
P
< 0.05). The observation group showed lower occurrence rate of complications compared with the control group (
P
< 0.05).
Conclusions:
Balloon kyphoplasty can significantly improve the image indices of patients with multiple osteoporotic vertebral fractures and relieve their pain degree and daily life disturbance. Balloon kyphoplasty exhibited a low occurrence rate of complications and high safety and is, thus, worthy of clinical applications.

A cross-sectional study of cytomegalovirus retinitis in HIV-1 infected adults in Nigeria
p. 293
MA Adeiza, AG Habib
DOI
:10.4103/njcp.njcp_82_18
PMID
:30837414
Background:
Cytomegalovirus (CMV) retinitis is one of the most important opportunistic infections in HIV-infected patients in developing countries before the introduction of highly active antiretroviral therapy. In Nigerian and African HIV populations, CMV retinitis is under-reported.
Patients and Methods:
In a cross-sectional study, 250 HIV-infected adults ≥18 years were recruited by systematic random sampling from March to August 2013. Using a structured questionnaire, information was obtained on socio-demographic characteristics and symptoms of visual impairment. HIV disease was staged according to the WHO clinical staging, and CD4+ T-lymphocyte count was measured. Participants with symptoms of impaired vision and/or CD4+ T-lymphocyte count <50 cells/μL had indirect ophthalmoscopic examination of the retina to detect CMV related eye lesions.
Results:
Two hundred and fifty adults were HIV-infected, out of which 114 (46%) were males and 136 (54%) were females. The mean age of study participants was 35 years. History of impaired vision was reported by 21 (8.4%) of participants. The right eye was involved in 7 (33%), the left eye in 4 (19%), and both eyes in 10 (48%) of participants. The predominant symptoms were blurred vision 9 (43%), floaters 9 (43%), and blindness 3 (14%). Among participants who had indirect ophthalmoscopy, 3 (1.2%) had characteristic retinal changes suggestive of CMV retinitis. Two (67%) of patients with CMV retinitis were females and 1 (33%) was male. Mean CD4+ count was 25.33 ± 14.19 and all were WHO HIV clinical stage 4 with death occurring within 6 months of diagnosis.
Conclusion:
CMV retinitis though rare is associated with advanced HIV disease and attendant morbidity and mortality. We recommend integration of CMV diagnostic services and ophthalmological services as routine in HIV care and treatment programs in Nigeria targeted toward high-risk patients.

Factors associated with intraventricular hemorrhage among preterm neonates in Aminu Kano teaching hospital
p. 298
CC Egwu, WN Ogala, ZL Farouk, AM Tabari, AH Dambatta
DOI
:10.4103/njcp.njcp_154_18
PMID
:30837415
Background:
Intraventricular hemorrhage (IVH) is a severe complication among preterm neonates which can result in hydrocephalus, cerebral palsy, behavioural disorders, learning disabilities, or death. It is important to identify the factors associated with IVH in order to prevent these neurological consequences and reduce the resultant burden of neurological disease. Aim: To determine the factors associated with IVH among preterm neonates.
Design:
The study was prospective cross-sectional in design.
Subjects and Methods:
Ninety-nine preterm neonates who were < 37 completed weeks of gestation were recruited consecutively from the Special Care Baby Unit of a Tertiary Hospital. Transfontanelle ultrasonography was used to detect IVH and the factors associated with IVH were classified into: neonatal, maternal (prenatal), and clinical factors. Data were analyzed using SPSS version 16.0 for windows. Chi-squared test and Fisher's exact probability test were used as appropriate. The level of significance was set at
P
< 0.05. The association between these factors and IVH was evaluated by univariate and multivariate logistic regression analyses.
Results:
Among the 99 preterm neonates studied, 36 (36.4%) of them were between 28 and 31 weeks of gestation, whereas 63 (63.6%) were between 32 and 36 weeks of gestation. In univariate analysis, the factors found to be associated with IVH were lower gestational age <32 weeks gestation, low Apgar score of <3 in 1 and 5 min, respectively, outborn status of neonates, lower social class, need for respiratory support, and blood transfusion. However, the lower gestational age (odds ratio [OR]: 10.9, 95% confidence interval [CI]:1.95–61.04) and respiratory support (continuous positive airway pressure (CPAP)) [OR: 52.24; CI: 3.40–721.84] were retained as significant predictors of IVH in the multivariate logistic regression model.
Conclusion:
The lower gestational age and respiratory support (CPAP) are independent predictors for IVH. Prevention of preterm delivery and improvement in interventions of neonatal care (CPAP) are necessary to prevent the risk for IVH especially in the early preterm neonates.

Primary molar pulpotomies with different hemorrhage control agents and base materials: A randomized clinical trial
p. 305
G Atasever, TI Keceli, S Uysal, HC Gungor, S Olmez
DOI
:10.4103/njcp.njcp_369_18
PMID
:30837416
Objective:
To evaluate the clinical and radiographical success of primary molar pulpotomies which used 15.5% ferric sulfate (FS) or 1.25% sodium hypochlorite (NaOCl) for hemostasis and zinc oxide–eugenol (ZOE) and calcium hydroxide (CH) pastes as base materials.
Methods:
In 29 healthy children, 80 primary molars were randomly allocated to one of the study groups: Group 1: FS-ZOE, Group 2: FS-CH, Group 3: NaOCl-ZOE, and Group 4: NaOCl-CH. After hemostasis with the respective solutions, pulp stumps and floor of the pulp chambers were covered with either ZOE or CH pastes. All teeth were restored with stainless steel crowns. Follow-up examinations were carried out at 1, 3, 6, and 12 months.
Results:
One tooth in Group 1 and two teeth in Group 4 were extracted because of pain and periapial pathosis at sixth month. After 12 months, clinical success rates of pulpotomies in Groups 1–4 were 95%, 100%, 100%, and 89.5%, respectively. The differences were not significant (
P
= 0.548). Radiographic success rates for Groups 1–4 were 80%, 88.9%, 78.9%, and 84.2%, respectively. No statistically significant difference was found (
P
= 0.968). Pain on percussion was the most observed clinical finding. However, internal root resorption was the most common radiological finding and it was observed significantly more in mandibular primary molars (
P
< 0.05).
Conclusion:
Both ZOE and CH can be preferred as base materials after hemostasis achieved by the use of 15.5% FS or 1.25% NaOCl in primary tooth pulpotomy.

In Vitro
evaluation of the wear of primary tooth enamel against different ceramic and composite resin materials
p. 313
A Bolaca, Y Erdogan
DOI
:10.4103/njcp.njcp_358_18
PMID
:30837417
Background:
Although there are several studies on permanent tooth wear caused by dental materials, studies concerning primary teeth are limited.
Aim:
To evaluate the wear of primary tooth enamel against different ceramic and composite resin materials.
Settings and Design:
In vitro
study. Materials and Methods: We assessed five materials (
n
= 10 per group): monolithic zirconia (group Z), lithium disilicate glass ceramic (group L), resin nanoceramic (group R), nanohybrid composite resin (group C), and primary tooth enamel (group E). The mesiopalatal cusps of primary maxillary second molars were used as antagonists. Wear tests were performed in a dual-axis chewing simulator, and the volume loss in the antagonist tooth was evaluated using a laser scanner and three-dimensional profiling system.
Statistical Analysis Used:
Data were statistically analyzed using one-way analysis of variance with Tukey's
post hoc
tests (
P
< 0.05). Results: The maximum antagonist tooth wear was observed in group L (3.84 ± 0.7 mm
3
), followed by groups C (3.68 ± 0.76 mm
3
), R (3.48 ± 0.71 mm
3
), Z (2.66 ± 0.65 mm
3
), and E (1.66 ± 0.42 mm
3
). Volume loss was significantly lesser in group Z than in groups L and C (
P
< 0.05), whereas there were no significant differences among groups L, C, and R.
Conclusion:
Within the limitations of this
in vitro
study, our findings suggest that zirconia should be used for full coronal coverage in primary tooth restorations because it causes lesser antagonist tooth wear than does lithium disilicate, resin nanoceramic, and nanohybrid composite resin.

The evaluation of preoperative and postoperative fetuin-A levels in patients with primary hyperparathyroidism
p. 320
M Keskin, C Culha, NE Gulcelik, LI Al, M Senes, Y Aral
DOI
:10.4103/njcp.njcp_323_18
PMID
:30837418
Objectives:
Our objective was to evaluate preoperative and postoperative serum fetuin-A levels in female patients with primary hyperparathyroidism (PHPT) and search for the relationship with parathyroid hormone (PTH) and vitamin D (25OHD). Although a role for fetuin-A is suggested in regulating bone mineralization, its function has not been completely defined.
Materials and Methods:
In this cross-sectional study, 43 female patients with PHPT and 30 healthy women were recruited as the control group. We evaluated 73 women because we had only women patients with PHPT. Of the 43 patients, 10 symptomatic and 23 asymptomatic patients were surgically treated, whereas 10 patients were not operated. In all 43 patients, 25OHD, PTH, fetuin-A levels, and bone mineral densitometry were evaluated. The biochemical parameters of 33 operated patients were reevaluated at the postoperative sixth week.
Results:
Fetuin-A levels of the patients with PHPT were significantly higher than that in the controls (56.6 ± 13.8 vs. 42.6 ± 20.7 ng/mL;
P
= 0.010). Fetuin-A levels of the operated patients were higher than nonoperated group. Furthermore, serum fetuin-A levels of the nonoperated patients were not different from those of controls. After parathyroidectomy, fetuin-A (41.5 ± 25.2 vs. 56.4 ± 13.7 ng/mL;
P
= 0.003), PTH [80.0 (51.5–137.5) vs. 211.0 (151.5–278.5) pg/mL;
P
< 0.001], and calcium (9.2 ± 0.7 vs. 10.7 ± 0.8 mg/dL;
P
< 0.001) values were found to be decreased significantly.
Conclusion:
In this study, fetuin-A levels of patients with PHPT were higher than those of the controls and significantly decreased after parathyroidectomy compared with the preoperative levels. Fetuin-A levels could be a beneficial marker to determine the changes in bone metabolism of the patients with PHPT and to detect the patients suitable for surgery.

p. 328
ET Basaran, Y Gokce
DOI
:10.4103/njcp.njcp_346_18
PMID
:30837419
Aims:
The aim of this study was to compare the effect of different restoration techniques on fracture resistance of endodontically treated teeth with different wall thicknesses.
Materials and Methods:
Extracted and endodontically treated 210 premolars were randomly divided into three thickness groups [2 mm (A), 1.5 mm (B), and 1 mm (C)] and, each group was further divided into seven restoration subgroups (
n
= 10): direct composite (control) (K), composite with fiber on cavity floor (KT), composite with fiber on occlusal level (KO), fiber post and composite (FP), inlay (L), fiber on cavity floor and inlay (LT), and inlay and fiber on occlusal level (LO). Fracture test was performed, and data were compared with Kruskal–Wallis and Mann–Whitney
U
tests (
P
< 0.05).
Results:
There were no differences between the subgroups in A and C statistically (
P
> 0.05). However, in B, KO subgroup showed statistically higher values (
P
= 0.039).
Conclusion:
Wall support of 2 mm was adequate, and support of 1 mm was completely insufficient. When the wall thickness was 1.5 mm, direct restoration with fiber at the occlusal level significantly improved resistance.

Effect of different surface treatments and ceramic primers on shear bond strength of self-adhesive resin cement to zirconia ceramic
p. 335
NE Saleh, MC Guven, G Yildirim, F Erol
DOI
:10.4103/njcp.njcp_394_18
PMID
:30837420
Aims:
To evaluate the effect of different surface treatments and ceramic primers on the shear bond strength (SBS) of self-adhesive resin cement to zirconia ceramic.
Materials and Methods:
A total of 40 zirconia discs (10 mm in diameter and 3 mm in height; StarCeram Z-Med, H.C. Starck, Selb, Germany) were prepared from pre-sintered zirconia blocks. Discs were divided into two groups according to surface treatment: (a) airborne particle abrasion (sandblasting) with 50-μm Al

O
3
particles and (b) 9.5% hydrofluoric acid etching. Each of these groups was subdivided into two groups according to the type of primer applied: (a) Z-Prime Plus primer and (b) Clearfil Ceramic Primer. A self-adhesive resin cement (Multilink Speed, Ivoclar Vivadent, Schaan, Liechtenstein) was used to bond with polyethylene molds. All specimens were tested at thermocycled (5000 cycles at 5–55°C for 30 s) conditions. The SBS of the luting cement to the ceramic was measured in a universal testing machine (1 mm/min).
Results:
The sandblasted groups showed significantly higher SBS values than the acid-etched groups for both primers (
P
= 0.0001). Independent of the surface treatment, the Z-Prime Plus primer groups showed higher SBS values than the Clearfil Ceramic Primer groups (
P
= 0.0001).
Conclusions:
Sandblasting is a more effective method to increase bond strength on zirconia ceramics than hydrofluoric acid etching, and the application of Z-Prime Plus primer increases SBS better than Clearfil Ceramic Primer.

Clinical and radiographic characterization of primary seminomas and nonseminomatous germ cell tumors
p. 342
L Gu, L Zhang, N Hou, M Li, W Shen, X Xie, Y Teng
DOI
:10.4103/njcp.njcp_448_18
PMID
:30837421
Background:
Primary malignant mediastinal germ cell tumors (PMMGCTs) including seminomas and nonseminomatous germ cell tumors (NSGCTs) are rare, and sometimes the diagnosis is very difficult.
Purpose:
The purpose of this study is to compare the clinical characteristics, biomarkers, and imaging findings of seminomas and NSGCTs and to determine whether these features could help distinguish these two types of PMMGCT.
Material and Methods:
A retrospective study of 24 male patients with histopathologically proven PMMGCT was performed. We collected the information of computed tomography (CT) (the scan area ranged from the apex of lung to the costophrenic angles) and magnetic resonance imaging blood test and histology characteristics of these patients.
Results:
Twelve of 24 cases were confirmed to be seminomas, whereas the other 12 cases were NSGCTs. Alfa-fetoprotein (AFP) was found to be elevated in all patients with NSGCT, whereas none of the patients with seminomas had elevated AFP level. Beta-human chorionic gonadotropin (β-HCG) level was elevated in all the patients with seminomas (seven/seven), whereas in NSGCT only two of seven patients had elevated β-HCG. Lactate dehydrogenase level was increased in five of the nine patients with seminomas, as well as in the eight patients with NSGCT. CT imaging revealed that 12 masses from the seminoma group were homogeneous, soft tissue opacity and showed minimal contrast enhancement. On the contrary, all 12 NSGCT cases showed cystic and solid masses; on contrast-enhanced CT, heterogeneous enhancement was found on the capsule of the tumor, septum, and solid masses.
Conclusion:
Seminomas and NSGCT showed different profiles of tumor biomarkers and radiographic features. Evidence from serum test, histopathological analysis, and imaging should be combined to ensure the accurate diagnosis of these two types of PMMGCT.

In-vitro
study on thermal changes during implant drilling with different irrigation volumes
p. 350
U Mercan, M Sumer, OA Kaya, I Keskiner, DG Meral, O Erdogan
DOI
:10.4103/njcp.njcp_417_18
PMID
:30837422
Objective:
Irrigation with saline is one of the essential methods for reducing the heat generated during dental implant osteotomy. High irrigation volume impairs visibility of the surgical field, thus complicates the surgery. In this study, we aimed to determine the optimal irrigation volume for heat reduction during dental implant drilling.
Materials and Methods:
Thirty-two implant osteotomies were prepared on four fresh cow ribs. Heat generated during the final implant drilling was measured both with infrared thermography and thermocouple method. Initial and maximum temperatures were measured at four different irrigation volumes; 32, 44, 56, and 68 ml/min.
Results:
Both measurement methods showed that the amount of temperature rise is associated with the irrigation volume during implant drilling. There is no further decrease in temperature rise above irrigation volume of 56 ml/min.
Conclusion:
Saline irrigation with 56 ml/min provides sufficient heat reduction during dental implant drilling and higher irrigation volumes are not necessary.

Defining apolipoprotein B treatment targets
p. 355
GO Ayoade, MA Kuti
DOI
:10.4103/njcp.njcp_348_17
PMID
:30837423
Background:
Apolipoprotein B (apo B) has been widely reported to be a better predictor of cardiovascular risk than low-density lipoprotein cholesterol (LDL-C). This is the reason apo B treatment target values based on the equivalence to LDL-C values in healthy population has been advocated using percentiles from population studies. The aim of this study was to determine the apo B values equivalent to currently used medical decision targets for LDL-C concentration in a population of healthy Nigerians and examine for any demographic influence.
Materials and Methods:
A total of 252 apparently healthy individuals (89 males, 163 females), between the ages of 30 and 65 years were selected from core health workers (medical and nursing staffs) of University College Hospital Ibadan between December 2015 and May 2016. Serum lipids and apo B were measured using enzymatic and immunoturbidimetry method, respectively.
Results:
The mean apo B of the study population were 94 and 98 mg/dL in men and women, respectively. Mean apo B concentration was significantly higher in the female participants in the age groups above 55 years. LDL-C concentrations of 100, 130, 160, and 190 mg/dL corresponded to the 15
th
, 55
th
, 87
th
, and 95
th
percentile, respectively. The corresponding apo B concentrations were 73 mg/dL (15
th
percentile), 95 mg/dL (55
th
percentile), 124 mg/dL (87
th
percentile), and 145 mg/dL (95
th
percentile). The group of participants with LDL-C of <130 mg/dL and the group with equivalent apo B of <95 mg/dL has the same clinical and biochemical characteristics in both men and women.
Conclusion:
This study has defined apo B targets that may potentially be used to guide the initiation of therapy in persons with dyslipidemia. It has also demonstrated the population level relationship that exists between apo B and LDL-cholesterol and has shown the gender and age-related influence of apo B distribution in the population.

PMID
:30837424
Background:
Breast cancer is the most common female cancer in both developed and developing countries. This study was designed to determine the predictors of practice of breast self-examination among female undergraduate students of Ebonyi State University, Abakaliki, Nigeria.
Methodology:
This was a descriptive cross-sectional study. A three-stage sampling design was used to select 365 female students of the university. Data were collected using a pretested self-administered questionnaire. Completion of one academic year qualified students for inclusion. Good knowledge of breast self-examination was determined by proportion of respondents who scored 50% and above of 15 variables used to assess knowledge.
Results:
The mean age of the students was 22.1 ± 2.5 years. Majority (76.4%) were aware of breast self-examination and health workers; 37.0% were the major source of information. A minor proportion (5.8%) have had their close relatives diagnosed with breast cancer. Majority (55.3%) had good knowledge of breast self-examination. Majority (63.6%) have ever-practiced breast self-examination; however, only 15.9% of the respondents examined their breasts on a monthly basis. Predictors of ever-practiced breast self-examination included having good knowledge of breast self-examination (adjusted odds ratios [AOR] =6.4, 95% CI: 3.9–10.4), having a close relative diagnosed with breast cancer (AOR = 4.0, 95% CI: 1.1–15.1), and mother of respondent being self-employed (AOR = 0.5, 95% CI: 0.5–1.5).
Conclusions:
Awareness of breast self-examination and practice were high among the respondents; however, only a minor proportion practiced breast self-examination every month. Having good knowledge of breast self-examination was associated with its practice. Having a close relative diagnosed with breast cancer encouraged the respondents to prevent the occurrence of breast cancer, thus enabling the practice of breast self-examination. Moreover, the practitioners of breast self-examination taught and encouraged others to examine their breasts. There is a need to increase knowledge of breast self-examination through public health education using the media.

Materials and Methods:
Thirty cadaveric cow brains were used in this experimental feasibility study. Experimental materials were divided into two groups: In Group I, the microsurgical separation of the intrinsic brain parenchyma was performed by using the retraction of microsurgical basket separator. In Group II, the same microsurgical dissections were performed without microsurgical basket separator. The difficulty and suitability of the procedure was divided as three degree: very easy, easy, and difficult.
Results:
In Group I (
n
= 30), 20% fresh cadaveric cow brains, the difficulty of the dissection was evaluated as difficult; 60% of the brains were dissected with easy procedure. The remaining 20% of the brain dissection was evaluated as very easy. In Group II (
n
= 30), 40% fresh cadaveric cow brains, the difficulty of the dissection was evaluated as difficult; 53.33% of the brains were dissected with easy procedure. The remaining 6.67% of the brains were evaluated as very easy. The significance level was set at a
P
value of <0.046 in all statistical analyses.
Conclusion:
This study showed that easily performing biopsy procedure and protecting the brain tissue with using of biopsy basket microseparator are feasible. It is thought that this instrument may make a contribution to the practical microsurgery in the protecting brain tissue and adequately performing of biopsy.

PMID
:30837426
Objective:
The aim of this study was to investigate the effect of oxidative stress and antioxidant situation on chronic otitis media with effusions (COME) and acute otitis media (AOM) in children.
Methods:
A total of 107 children aged 2 to 13 years were examined. The study included 31 patients with AOM, 39 with COME, and 37 as control subjects. Venous blood samples were collected from all patients and control group. Myeloperoxidase (MPO), glutathione peroxidase (GPx), catalase (CAT), nitric oxide (NO), malondialdehyde (MDA), and superoxide dismutase (SOD) activities were investigated in the blood samples.
Results:
The mean age was found as 7.3 ± 3.3 in the AOM group, 6.2 ± 3.0 in the COME group, and 6 ± 2.4 in the control group. MPO, NO, and CAT were found to be significantly higher in the AOM and COME groups than the control groups (
P
= 0.040,
P
= 0.001, and
P
= 0.044).
Conclusion:
In this study, we observed activity of antioxidant and oxidative stress in children with COME and AOM. These results may be important in the diagnosis of these diseases and may affect the theurapeutic approach to the patients with COME and AOM.

Background:
Hyperhomocysteinemia (HHcy) is the risk factor for cardiovascular disease and stroke. However, the impacts on the genetic variation of methylene tetrahydrofolate reductase (MTHFR) on plasma homocysteine levels in the Northeast Chinese population have not been studied. Therefore, this study was carried out to determine the relationship between HHcy and MTHFR gene variation, and whether it was influenced by age and sex of the population in Northeast China.
Materials and Methods:
A total of 466 subjects were randomly enrolled in this study. According to the homocysteine levels (Hcy ≥ 15 μmol/L) of the subjects, they were divided into hyperhomocysteine (HHcy = 206) and normal homocysteine (Hcy = 260). Polymerase chain reaction/high-resolution dissolution curve and homocysteine determination kit methods were used for genotype testing and homocysteine detection, respectively.
Results:
High plasma homocysteine levels are associated with MTHFR 677T and 1298A [
P
< 0.00, odds ratio (confidence interval) = 1.842 (1.418–2.394) >1], which is related to increasing age (
P
range
= 0.0005–0.0161), with the homocysteine levels of males higher than females (
P
< 0.0001).
Conclusion:
High plasma homocysteine levels were linked to the MTHFR gene mutation. In addition, plasma homocysteine levels increased significantly with age with male's homocysteine levels higher than that of females.

DOI
:10.4103/njcp.njcp_105_18
PMID
:30837428
Aim:
The aim of this study was to investigate ELABELA (ELA) expression in benign and malignant renal tissues and expression differences in different nuclear grades of clear cell carcinomas.
Materials and Methods:
Patients that underwent surgery due to renal masses between the years of 2007 and 2017 were used. Control renal tissues (
n
= 23), papillary RCC (
n
= 23), clear cell RCC (CcRCC) [Fuhrman Grade1 (
n
= 23), Fuhrman Grade2 (
n
= 23), Fuhrman Grade3 (
n
= 23), Fuhrman Grade4 (
n
= 23)], and chromophobe RCC (
n
= 23) were included to the study. The Independent samples
t
-test was used for 2-point intergroup assessments and the one-way analysis of variance and posthoctukey test was used for the others. Values of
P
< 0.05 were considered statistically significant.
Results:
ELA immunoreactivity was observed in proximal and distal tubules in the kidney, but not in glomeruli in control tissues. When compared with control kidney tissue, a statistically significant increase was observed in ELA immunoreactivity in renal oncocytoma. In the chromophobe RCC, ELA immunoreactivity was significantly lower than control kidney tissue, whereas papillary RCC did not show ELA immunoreactivity. However, compared with control kidney tissue, ELA immunoreactivity was not observed in Fuhrman Grade 1 and Grade 2 CcRCC. Also, there was a significant decrease at Fuhrman Grade 3 and Grade 4 CcRCC compared with control kidney tissues. In the statistical analysis of ELA immunoreactivity among the Fuhrman nuclear grades of CcRCCs, The ELA immunoreactivity was higher at Grade 4 CcRCC than Grade 1, Grade 2, and Grade 3.
Conclusion:
ELA is a usefull molecule to differentiate benign and malign renal tumors. But further broad and comprehensive studies are needed to investigate cellular and molecular mechanisms of ELAs on malign transformation.

p. 393
M Tecellioglu, S Alan, S Kamisli, FS Tecellioglu, O Kamisli, C Ozcan
DOI
:10.4103/njcp.njcp_386_18
PMID
:30837429
Background:
The aims of our study were to compare the histomorphological characteristics of carotid plaques and glycosylated hemoglobin (HbA1c), which are risk factors for ischemic stroke, in patients who underwent carotid endarterectomy for carotid artery stenosis. Moreover, we aimed to identify the structures that were histologically affected by symptomatic carotid plaques in cases with elevated HbA1c.
Materials and Methods:
A total of 64 patients who presented with ischemic stroke and had not previously been diagnosed with diabetes were retrospectively evaluated. All stroke risk factors were reviewed. Carotid plaques were graded separately by two different pathologists through microscopic assessment of the following parameters: plaque rupture, lipid core, fibrous cup thickness, inflammation, intraplaque hemorrhage, thrombus, calcification, necrotic core, and neovascularization. An HbA1c value <6.3% was accepted as normal or indicative of prediabetes (group 1), whereas patients with values ranging between 6.3-7.4%, 7.5-8.4%, and >8.4% were categorized into the effectively controlled (group 2), less effectively controlled (group 3), and uncontrolled (group 4) groups, respectively.
Results:
The mean age of the patients was 73.0 ± 4.5 years in group 1, 69.7 ± 2.3 years in group 2, 66.0 ± 8.5 years in group 3, and 62.7 ± 7.1 years in group 4. A negative correlation was present between age and HbA1c. Smoking, hypertension, low-density lipoprotein cholesterol levels, and triglyceride levels were not significantly different among the four groups. According to the HbA1c classifications, the fibrous cup thickness was 2.64 ± 0.3 mm in group 1, 1.85 ± 0.4 mm in group 2, 1.68 ± 0.5 mm in group 3, and 1.45 ± 0.6 mm in group 4. The fibrous cup became thinner as the HbA1c value increased. Other parameters of unstable carotid plaques did not differ among the HbA1c groups.
Conclusions:
Increased HbA1c values seem to contribute to plaque instability through the formation of a thin fibrous cup. Thus, of the carotid artery plaque parameters including fibrous cup thickness, plaque rupture, lipid core, inflammation, intraplaque hemorrhage, thrombus, calcification, necrotic core, and neovascularization, fibrous cup thickness is the only histomorphological feature that affected by HbA1c.

Ultrasound-accelerated catheter-assisted thrombolytic therapy applicatıons in deep vein thrombosis
p. 399
H Kartal, D Erer, GL Oktar, MH Zor, M Arslan, K Akkan
DOI
:10.4103/njcp.njcp_27_18
PMID
:30837430
Background:
Ultrasound-accelerated catheter-directed thrombolysis (UCT) increases the invasion of thrombolytic agent into the thrombus using ultrasonic energy, provides less infusion of thrombolytic agent, reduces complication, and post-thrombotic syndrome (PTS) development rates. For these reasons, this procedure is a promising method for the treatment of deep vein thrombosis (DVT).
Materials and Methods:
Patients diagnosed with DVT by ultrasonography (USG) who underwent UCT between May 2013 and August 2014 at Gazi University Hospital Cardiovascular Surgery Clinic were included in the study. The demographic characteristics and postoperative acute and long-term patency rates and deep venous insufficiency rates were evaluated retrospectively to determine the efficacy of the UCT procedure. Patients were classified as acute, subacute, and chronical DVT according to the onset of complaints. The efficacy of the UCT procedure was assessed by Doppler USG performed 6 months and 2 years after the procedure, and patients were re-evaluated for deep venous insufficiency and thrombus findings to determine the relationship between UCT procedure and deep venous insufficiency.
Results:
In acute phase, 57.1% (
n
= 8) complete and 35.7% (
n
= 5) partial openings were obtained. No complete patency was obtained in any of the subacute patients. However, partial openness rate was 60%. In patients admitted during the chronic period, complete patency was obtained in 20% (
n
= 8) and partial openings in 60% (
n
= 3). Although thrombolysis success was not considered as statistically significant, the success rate was numerically higher in the acute phase.
Conclusion:
As a result, UCT applications provide thrombolysis especially in acute deep vein thrombosis, preventing deep venous insufficiency and especially post-thrombotic syndrome formation. UCT prevents bleeding complications by keeping thrombolytic amount low and can be used as an endovascular method of high safety in patient population with high bleeding complications such as patients with malignancies.

DOI
:10.4103/njcp.njcp_145_18
PMID
:30837431
Objective:
Our goal was to evaluate the effect of previous history of direct vision internal urethrotomy (DVIU) on success rate of open urethroplasty in patients with bulbar urethral stricture.
Patients and Methods:
We analyzed 133 patients who underwent open urethroplasty for bulbar urethral stricture between January 2008 and May 2017. Patients with penile and fossa navicularis stricture were excluded. We evaluated the effect of previous history of DVIU on success rate of open urethroplasty in patients with urethral stricture. Success of open urethroplasty was defined as disappear of voiding symptoms with maximum flow rate above 15 ml/s. The patients were followed for complications and outcome.
Results:
Mean age was 54.05 ± 16.5 years. Mean length of stricture was 23.74 ± 10.23 mm. Mean follow-up was 39.77 ± 28.0 months. A total of 76 patients (57.1%) had no history of DVIU. On the contrary, 15.8% had history of DVIU once, 12% had twice, and 15.2% had more than twice. Success rate of open urethroplasty in patients who had no history of DVIU was 84%. However, this success rate was 71.4% in patients who had history of DVIU (
P
= 0.001).
Conclusion:
DVIU is easy, simple, and noninvasive technique in treatment of urethral stricture, so it is frequently used among urologists. However, it could not be an alternative technique to open urethroplasty. Internal urethrotomy can be used in some certain indications. Success rate of open urethroplasty can be affected by previous history of any endoscopic procedures.

DOI
:10.4103/njcp.njcp_341_18
PMID
:30837432
Background:
Breast cancer keeps its importance as an important health problem in developing countries like Turkey. Therefore, breast cancer screening and early diagnosis are more important for these countries. Although there are debates about breast self- examination, it is still involved in breast cancer screening programs in many countries.
Aim:
This study aimed to determine university students' knowledge and practice of Breast Self-Examination (BSE).
Materials and Methods:
The study universe consisted of all the female students studying at a public university. Sample size of 161 was calculated for a predicted event frequency. The research data were collected using a questionnaire.
Results:
A total of 73.3% of the subjects students had heard about BSE. Only half of these students had obtained additional information about BSE. While half of the students indicated that they did perform BSE, 33.3% reported doing so at regular intervals. The majority of the students were aware of BSE and its purpose. Only about half stated, however, that they practice it. Those who practiced BSE were not knowledgeable about how and when to perform it.
Conclusions:
In developing countries, to have adequate knowledge of BSE of young women and to do BSE, it is important to develop a consciousness of breast health and an awareness of breast cancer at this age.

Inhibitors among patients with hemophilia in Basra, Iraq – A single center experience
p. 416
AK Taresh, MK Hassan
DOI
:10.4103/njcp.njcp_388_18
PMID
:30837433
Introduction:
Inhibitor formation is a major complication of hemophilia treatment because it interferes with the clinical response to factor replacement and causes significant morbidity. This cross-sectional study was conducted to assess the presence and frequency of inhibitors among registered person with hemophilia and to identify risk factors associated with inhibitor development.
Patients and Methods:
A total of 143 hemophilics, 118 with hemophilia A (HA) and 25 with hemophilia B (HB), were enrolled for the study. Participant's clinical data were obtained through patient's medical records. Factor VIII and IX levels and the presence of inhibitors were assessed using a fully automated coagulometer. From the results of a Bethesda assay, patients were divided into those with high titers (≥5 BU) and those with low titers (<5 BU).
Results:
The patient's age ranged from 1 to 67 years with median of 13.8 years. Inhibitors were detected in 18.6% and none of HA and HB patients, respectively. Of the 22 patients with HA and inhibitors, 18 (82%) had high titer inhibitors. The frequency of inhibitors was significantly higher among patients with severe hemophilia, a history of early exposure (≤3 months) to factor VIII concentrate, and family histories of autoimmune disease and immune system challenges (
P
< 0.05). The independent risk factors associated with inhibitor development were severe hemophilia (95% CIs = 1.02–55.6, OR = 7.5) and immune system challenges (95% CIs = 1.14–5.99, OR = 2.6).
Conclusion:
Inhibitors were common among HA patients, and both severe HA and immune system challenges (surgery and trauma) are independent risk factors for inhibitor development.

Aims:
The aim of this
in vitro
study was to investigate the antimicrobial effects, nanohardness, and cytotoxicity of different glass-ionomer restorative materials in dentistry.
Materials and Methods:
The following glass-ionomer restorative materials were used in our study: Argion (VOCO, Germany), Zirconomer (Shofu Inc., Japan), EQUIA Forte (GC, Japan), Fuji II LC capsule (GC, Japan), and Fuji IX GP capsule (GC, Japan). For the cytotoxicity test, a cell culture without release liquids was used as the control group. Microdilution and a disk diffusion test were used to measure the antimicrobial activity. The MTT (3- [4,5-dimethylthiazol-2-yl] -2,5-diphenyltetrazolium bromide) assay was used to evaluate cytotoxicity. Nanohardness was measured using a nanoindenter device.
Results:
Our study determined that all restorative materials used in this study inhibited bacterial growth in cultures containing 1 × 10
2
cfu/ml of the bacterial concentrations
(Lactobacillus casei
and
Streptococcus mutans)
and that all restorative materials inhibited fungal growth in the cultures containing <1 × 10
2
cfu/ml of the fungal strains (
Candida albicans
). IC
50
values obtained for the cytotoxicity test were analyzed using the Chi-square test. After a 72-h incubation period, Zirconomer, EQUIA Forte, Fuji IX GP capsule, and Fuji II LG capsule showed statistically significant lower cell viability values. (
P
< 0.05). The Kruskal-Wallis analysis was performed on the values obtained from the nanohardness test; the differences between the groups were found to be significant (
P
< 0.05).
Conclusions:
All materials tested showed low antimicrobial activity, and the antifungal activity of these materials was found to be lower than their antimicrobial activity. Only Argion showed non-cytotoxic effect. Beginning with the group with the highest nanohardness values and ending with the lowest, the groups are ranked in the following order: Fuji II LC capsule, EQUIA Forte, Argion, Fuji IX GP capsule, and Zirconomer.

PMID
:30837435
Twin block is a commonly used appliance for correction of retrognathic mandible in growing patients. However, it has a drawback of causing lower incisor proclination, which reduces its potential of achieving maximum skeletal effects. Thus, we introduced a novel modification in the present design to facilitate greater anteroposterior effects in skeletal dimension. The aim of the present case reports is to evaluate the efficacy of this modified twin block. Here we present two cases treated with mini-implant-supported twin-block appliance, which successfully controlled the lower incisor position, thereby increasing the envelope for orthopedic correction in class II myofunctional therapy. This modification is useful in growing patients with retruded mandible to achieve maximum skeletal effects.

PMID
:30837436
The harmful effects of khat chewing on the oral mucosa membrane are still uncertain. Verruca vulgaris (common warts) is a benign lesion of skin and mucous membranes and can be caused by human papillomavirus. The lesions are typically self-limited but may vary in size and number. The occurrence on the floor of mouth is extremely rare. To the best of our knowledge, there are few number of oral lesions reported in connection with khat users. This case report shows that the chronic khat chewing has contributed to the development of verruca vulgaris warts that were confined to the chewing side of the mouth. A rare case of verruca vulgaris of the floor of mouth occurring in a 27-year-old Yamani male is presented with a discussion on etiopathogenesis and the treatment methods. Verruca vulgaris must be remembered in the differential diagnosis of the floor of mouth lesions, and surgical treatment may provide satisfactory outcomes.
