Authors: Manjunath Darshan A. , Radhakrishna Veerabhadra , Vepakomma Deepti 
Published: January 2022

Aims:
This study aimed to evaluate the outcome of perineal trauma in children and to a define protocol for their management.

Methods:
It is a retrospective study of children who presented with perineal injury between August 2012 and December 2020. The patients were classified into three groups: Group-1 included children with perineal and genitourinary injuries; Group-2 included patients with perineal and anorectal injuries; and Group-3 included patients with perineal, genitourinary, and anorectal injuries. All patients underwent primary repair. Those with full-thickness anorectal injury underwent an additional covering colostomy, while urethral disruption was initially managed by a diverting suprapubic cystostomy (SPC).

Results:
A total of 41 patients were studied. Impalement injury (n = 11; 27%) and sexual abuse (n = 11; 27%) were the most common mechanisms of injury. Twenty (49%) patients had anorectal injuries with 10 (24%) each of partial-thickness and full-thickness injury. There were 24 (59%) genital injuries and five (12%) urethral injuries. One patient each developed anal and vaginal stenosis, both were managed with dilatation. One patient developed a rectovaginal fistula repaired surgically at a later date.

Conclusion:
Perineal injuries with resultant anorectal or genital damage require a careful primary survey. Following stabilization, an examination under anesthesia as a set protocol will help determine the treatment strategy. A colostomy is essential in the acute management of severe anorectal injuries to reduce local complications and preserve continence. Urethral injuries may warrant an initial diverting SPC in selected cases.

ABSTRACT

Background and Aim:
Generation defines as a group of people who were born in a same interval of year and shares similar life events at critical developmental stages, values, behaviors, and significant reactions. The aim of this clinical study was to assess self-awareness of dental health of X, Y, and Z generations in Turkey.

Materials and Methods:
Total of 239 individuals were divided into three homogenous groups X Generation (X Gen; n = 80), Y Generation (Y Gen; n = 80), and Z Generation (Z Gen; n = 79) by their date of birth 1965–1980; 1981–2000; 2001–2013, respectively. Self-rated caries status, frequency of tooth brushing, frequency of dental visits, and actual caries status were recorded. Self-awareness was calculated as the extraction of the numbers of actual caries and self-rated caries and coded as △ Caries.

Results:
Mean Dental caries status was recorded using the number of decayed, missing or filled teeth (dft/DMFT) was 4.92 for X Gen; 4.68 for Y Gen; 3.66/3.51 for Z Gen individuals, respectively. Actual caries and self-rated caries were significantly incompatible with each other in all study groups (<0.001). △Caries were insignificant in X, Y, and Z Generations (>0.05); nevertheless, self-awareness (self-rated caries = actual caries) of Z Gen were found numerically more (23%) compared to other groups. Tooth-brushing habits of all individuals were mostly once-a-day (>0.05). Mean frequency of dental visits were once in a 3.5; 2.9; 1.5 years for X, Y, and Z Gens, respectively.

Conclusion:
There is no significant correlation between frequency of dental visits and self-awareness measures. Oral health education should urgently point out for all generations by dental professionals, media, and governmental authorities including preventive methods, oral hygiene instructions all aimed at preventing caries and raising self-awareness.
The sole and combined effects of gelatin-thrombin matrix and freeze-dried bone allograft on early bone healing
Authors: Kasapoglu MB , Cebi AT , Olgac NV , Keskin C 
Published: January 2022

ABSTRACT

Aims:
Gelatin-thrombin matrix (GTM) is a hemostatic agent with applications in maxillofacial surgery consisting of human-derived thrombin and bovine-derived gelatin matrix. The aim of this study was to evaluate the efficacy of GTM alone or with freeze-dried bone allograft (FDBA) in improving early bone healing.

Materials and Methods:
Forty-six adult male Sprague-Dawley rats were used. All animals were randomly assigned to a control group (n = 4) and three study groups (n = 14). Each group was divided into two subgroups for histomorphometric and histological analyses at weeks 1 and 4. The new bone formation, inflammation, fibrosis, necrosis, foreign body reaction, and bone healing scores were evaluated based on the histopathological findings. Multiple comparisons were performed using the Kruskal–Wallis test. Variables that were not normally distributed were evaluated using the Mann–Whitney U test.

Results:
At 1 week, the GTM + FDBA group showed less bone formation (mean ± SD: 0.08 ± 0.03 mm2), compared with the study and control groups (FDBA: 0.15 ± 0.06 mm2; GTM: 0.13 ± 0.06 mm2). At 4 weeks, the GTM group (0.48 ± 0.1 mm2) showed more bone formation than the GTM + FDBA group (0.33 ± 0.17 mm2). Foreign body reactions were observed at weeks 1 and 4 in all GTM-containing groups.

Conclusions:
Within the limitations of this study, GTM group did not show a significant difference in bone formation compared with the control group. GTM did not inhibit bone healing at 1 and 4 weeks, and no significant difference was observed compared with the control groups. GTM was more effective for bone healing when administered without FDBA. GTM is considered safe when bone hemorrhage is encountered.

Published: January 2022

ABSTRACT

Background:
Despite the reports of carpal tunnel syndrome (CTS) being commonplace in Saudi Arabia, there is scarcity of cross-sectional or prospective studies detailing the profile of nerve conduction study (NCS) findings in patients with CTS.

Objective:
The study aimed to evaluate the neurophysiologic profile of CTS with the view to finding the determinant of abnormal findings in clinically diagnosed cases of CTS in a population of Saudis.

Methods:
Nerve conduction study was performed on consecutive patients with clinically diagnosed CTS. Median sensory, ulnar sensory, radial sensory median motor and ulnar motor nerves were assessed. The nerve conduction parameters measured were median and ulnar sensory peak latency, amplitude and velocity. Median conduction velocity, distal latency, and amplitude were also measured. Comparative median-ulnar and median-ulnar-digit 4 studies were done and the severity of CTS was determined. Data was analyzed using STATA software version 12.

Results:
A total of 152 patients, comprising 59 males and 93 females (mean age of 42.7 years) with clinically diagnosed CTS were seen during the study period. About 72.4% patients had numbness and paresthesia in the affected fingers, 66.5% had pain in the hands, and 10.5% had weakness in the affected hands. Majority of the patients (62%) had bilateral clinical features. Carpal tunnel syndrome was confirmed with NCS in 84 (55.26%) patients. Presence of weakness in the affected hand, positive Phalen' sign, and positive Tinel's sign in patients appear to predict [6.1 (1.2—30.7), 3.9 (1.2-30.2), and 4.9 (1.4-17.0) respectively] abnormal NCS findings after adjustment for age, gender and the presence of DM.

Conclusion:
The study revealed that over half of the patients with CTS had NCS/ Electromyography (EMG) abnormalities. Presence of hand muscles weakness, positive Phalen and Tinel's signs predict abnormal findings on NCS/EMG in patients with CTS.

Published: January 2022

ABSTRACT

Background:
Pulpal involvement, secondary to dental caries, is not uncommon and is a challenging task for pediatric dentists. Morphological differences in root canal of deciduous teeth increases the complexity of management. The aim of this study was to compare two rotary file systems and hand instrumentation for root canal preparation in regard to canal transportation, centering ability ratio, and dentin thickness using cone-beam computed tomography (CBCT).

Methods:
A total of 72 canals from 24 freshly extracted mandibular deciduous second molars were divided into a set of 8 teeth, then prepared using 2 rotary files systems: the Kedo-S pediatric file system (Group A) and Pro AF Baby Gold file system (Group B) were compared to hand instrumentation (Group C). CBCT scans before and after root canal preparation were used to evaluate tested parameters. Instrumentation time for all three techniques was also measured using a chronometer.

Results:
Although rotary file systems have shown superior results in root canal preparation as compared to hand instrumentation, no significant differences were observed between all the groups for canal transportation and dentin thickness at all three levels of prepared canals. A comparison of centering ability ratio between all the groups was found to be statistically significant only at the cervical level. A significant difference was observed between hand instrumentation using K-files (117.3 s) and both rotary systems (Kedo-S (81 s) and Pro AF Baby Gold (81.5 s)) in terms of canal preparation time (P < 0.001).

Conclusions:
Both tested rotary systems and hand instrumentation demonstrated comparable canal preparation results, with differences that were statistically non-significant in most tested parameters, without shaping errors. However, both the rotary systems were more efficient and faster than hand instrumentation.

Authors: Raffa LH , Abudaowd O , Bugshan N , Fagih SN , Hamdi T 
Published: January 2022

ABSTRACT

Aim:
To assess and compare ophthalmologic and morphologic outcomes between school-age children born moderate-to-late preterm and those born at term.

Patients and Methods:
Fifty children born moderate-to-late preterm (gestational age 32 weeks + 0 days to 36 + 6 days, age range 5-10 years) at a tertiary university hospital were age- and sex-matched to full-term controls. Visual acuity, refractive errors, ocular biometry, macular, and optic nerve assessments with optical coherence tomography were investigated and compared between cases and controls.

Results:
No differences in visual acuity or refraction were detected between the study groups. The difference in refractive error was not significant between the groups. Marked differences were observed in the anterior chamber depth, which was shallower in the preterm group (P = 0.044); however, no difference in total axial length was observed. The preterm and control groups significantly differed in terms of central macular thickness (247 ± 19 μm versus 235 ± 22 μm; P = 0.005 right eye); however, the groups did not significantly differ in foveal thickness. Central subfield thickness was also markedly greater in the preterm than in the control children (246.89 ± 19.1 μm versus 236.12 ± 23.3 μm, P = 0.015). No significant differences in mean parafoveal/perifoveal thicknesses or optic nerve parameters were observed between both groups.

Conclusion:
Significant differences between moderate to late preterm and full-term groups in regards to anterior chamber depth, central macular thickness, and central subfield thickness were found. It is important to recognize that being born preterm might have an impact on some ocular structures. Larger population-based studies should be conducted to study the long-term sequelae of moderate-to-late prematurity in our children.

Evaluation of Diagnostic Performance of MDCT Coronary Angiography in Comparison with Conventional Coronary Angiography
Authors: Kumar Sachin 
Published: January 2022

Abstract

Background: Coronary artery disease is now becoming increasingly prevalent than before especially in younger age groups. We in the current study tried to evaluate the potential of 128 slice MDCT coronary angiography for the detection of stenotic coronary lesions by comparing the results of computed tomographic coronary angiography to a gold standard set by Conventional coronary angiography.

Methods: A total of n=30 patients with clinically suspected Coronary artery disease. They were evaluated with 128 Slice CT Scanner (PHILIPS INGENUITY) and conventional coronary angiography. All patients were examined with a 128 slice MDCT scanner (Philips Ingenuity 128 slice Netherlands) using standard cardiac CT protocol. Gantry rotation time was 400 ms with a half sector acquisition protocol and multisector reconstruction permitting an effective temporal resolution between 50 and 200 ms depending on patient heart rate.

Results: In the n=30 Patients included in the study with CCA, the n=450 coronary segments included in the study were found to contain a total number of n=138 stenoses among them non-significant stenoses. The accuracy of MDCT detection of coronary stenoses greater than 50% diameter of vessel lumen is about 94.78. When raising the threshold for stenosis from 50% to 70% of the vessel lumen, so that only hemodynamic relevant stenoses enter the evaluation, the sensitivity decreases from 88%. The MDCT detection in the patient group with heart rates below 60 beats per minute higher values for sensitivity 93% and specificity 97% were observed, compared to sensitivity 87% and specificity 93% of the patient group with heart rates above 60 beats per minute.

Conclusion:The present study revealed that a high negative predictive value (98.08%)suggests that 128- Slice MDCT coronary angiography is a good screening modality for evaluation of patients with mild to intermediate-risk factors who might otherwise require invasive angiography.

Published: January 2022

Vestalis gracilis (Rambur, 1842) is a forest stream damselfly belonging to the family Calopterygidae. Its last-stadium larvae and exuviae are described and illustrated based on laboratory-raised specimens from Thailand, and observations of agonistic behavior are provided. The taxonomical characters of V. gracilis larvae are similar to those of V. amoena. They exhibit synapomorphic characters such as posterlaterally directed protuberances on the postocular lobes, posterior margin of median lamella obliquely truncate, and two setae on labial palps. Vestalis gracilis and V. luctuosa bear eight antennal segments whereas seven antennal segments are found in V. amoena. The most significant difference between V. gracilis and V. luctuosa is that V. luctuosa has posterolaterally directed protuberances on the postocular lobes and an obliquely truncate posterior margin of the median lamella.
