The main aim of this study was to compare refraction measurements with and without cycloplegia from two refractors devices, (TRK-2P autorefractometer (TRK-2P) and wavefront-based refraction Visionix 130 (VX130)) in children and adolescents. This descriptive observational study included 20 myopic eyes and 40 hyperopic eyes measured in two different Spanish hospitals. Cycloplegia was carried out by three drops of cyclopentolate hydrochloride 1% (Colircusí cycloplegic, Alcon Healthcare S.A., Barcelona). The mean age of the myopia group was 12.40 ± 3.48 years; for the hyperopia group, the mean age was 7.37 ± 2.47 years. In the myopia group, autorefraction and wavefront-based refraction did not show clinically significant differences in any components between with and without cycloplegia. The hyperopia group showed statistical and clinically significant differences in sphere and SE components between relaxed and non-relaxed states of accommodation, although the cylindrical components were not clinically different. In this study, we considered a value of ≥0.50D as a clinically significant difference in refraction. Therefore, both devices were capable of obtaining accurate refractions without cyclopegia in myopia children, although they did not avoid instrument myopia and accommodation involved in hyperopia children. Moreover, both refractometers could be useful for astigmatism monitoring in children without the need for cycloplegic drops.

AbstractGradual replacement of the mercury thermometers with alternative devices is ongoing around the world in a bid to protect human health and the environment from the adverse effects of mercury. However, to reduce the risks of misdiagnosis, unnecessary treatments, and omission of care in pediatric populations, more evidence on the reliability of alternative thermometers is needed. The aim of this comparative observational study was to detect any differences in temperature measurements between the use of the axillary mercury thermometer and the alternative techniques. Temperature values in degree Celsius (°C) were measured in a group of Albanian children aged up to 14 years using mercury and digital axillary thermometers, as well as forehead and tympanic infrared thermometers. The digital axillary device, compared with the mercury one, showed no clinically significant difference in the mean values (− 0.04 ± 0.29 °C) and the narrowest 95% level of agreement (+ 0.53 °C to − 0.62 °C) in the paired comparisons. For cut-off point of 37.5 °C, the digital axillary thermometer showed the highest levels of sensitivity (72.5%) and specificity (99.1%) in detecting fever. This study indicates that the digital axillary thermometer may be the better option since it adequately balances accuracy, safety, and children’s comfort.

BACKGROUND An ideal surgery to remove hypertrophied adenoid mass should be safe, with less bleeding and operation time along with post-operative improvement in the eustachian tubal ventilation and normal respiration. It should also have low morbidity and mortality. Among the various methods described for its removal, the two commonly used methods are conventional cold curettage method and coblation technique. The purpose of this study was to collate the safety and efficacy of endoscopic coblation adenoidectomy with the conventional curettage adenoidectomy. METHODS A prospective comparative study with fifty patients was studied who underwent adenoidectomy. Twenty five patients underwent endoscopy assisted coblation adenoidectomy and twenty five patients underwent regular adenoidectomy by curettage. RESULTS Patients who underwent coblation adenoidectomy showed better results during follow up in terms of completeness of removal. 80 % of children undergoing regular adenoidectomy by curettage method showed remnant adenoid tissue in the nasopharynx at the end of the procedure. But it was 6 % among the children undergoing endoscopic assisted coblation adenoidectomy. The mean duration of operation was higher for endoscopic assisted coblation adenoidectomy which was significant statistically. The mean blood loss was 30.36 ml in regular curettage adenoidectomy; 10.6 ml with endoscopic coblation adenoidectomy. The grading of pain was significantly lower in endoscopic assisted coblation adenoidectomy. There was no significant difference between two groups in terms of eustachian tube function after surgery. CONCLUSIONS Coblation adenoidectomy has significant advantages over conventional adenoidectomy in terms of completeness of removal, reduced blood loss, and lower post-operative pain grade.

Abstract A comparative study on the nursery culture of the spat of the tropical oyster, Crassostrea iredalei, in an earthen pond and a mangrove canal was conducted over two months. The results revealed no differences in the absolute growth rate determined by shell width between the two culture sites (P < 0.05). Sub-adult oysters cultured in the mangrove canal showed a higher absolute growth rate in shell length and a higher daily growth rate than the oysters cultured in the earthen pond (P < 0.05). The mean survival rate of sub-adult oysters cultured in the earthen pond (99.8 ± 0.2%) was significantly higher than for those cultured in the mangrove canal (66.7 ± 31.4%). Decreased density from the loss of sub-adult oyster nursery culture in the mangrove canal led to higher growth performance than in the earthen pond. However, no difference was found for the fraction of oysters larger or smaller than 5 cm for the two culture sites (P < 0.05). A significant difference was noted in the Condition Index (CI) between the two culture sites (P < 0.05). The high primary productivity in mangroves is a major supporter of higher CI in sub-adult oysters cultured in mangrove canals versus in earthen ponds. Water exchange in the earthen pond to maintain calcium and magnesium concentrations resulted in no differences in the shell compressibility of sub-adult oysters compared with those cultured in the mangrove canal.

ABSTRACT Objective: To determine the prevalence of hepatic steatosis (HS) in children and adolescents with cystic fibrosis (CF) and associate it with nutritional status. Methods: Cross-sectional study with children and adolescents with CF diagnosis. Weight and height were used to calculate the body mass index (BMI) and subsequent classification of the nutritional status. The midarm circumference (MAC), triceps skinfold thickness (TSF) and midarm muscle circumference (MAMC) were used to evaluate body composition. Abdominal ultrasonography was performed for diagnosis of HS. The statistical tests used were Student’s t test, Mann-Whitney test and chi-square test with significance level of 5%. Results: 50 patients with CF were evaluated, 18 (36%) were diagnosed with HS (Group A) and 32 (64%) without HS (Group B). The mean age of Group A was 13,2±4,9 years old and Group B 11,7±4,9; for BMI, the value for Group A was 18,0±4,1 and Group B was 15,7±3,8; the TSF of Group A was 8,4±3,5 mm and Group B was 7,0±2,5 mm. For these variables, there was no significant difference between the groups. The mean of MAC and MAMC differed significantly between the groups, being higher in the HS group, with p values of 0,047 and 0,043. Conclusions: The frequency of HS in patients with CF is high and it is not related to malnutrition, according to the parameters of BMI, TSF and MAMC. The values of MAC and MAMC indicated a greater reserve of muscle mass in patients with HS.

Abstract Objective: To evaluate skeletal and dentoalveolar changes induced by the eruption guidance appliance in the early mixed dentition. Materials and Methods: Pre- and posttreatment cephalometric radiographs of 115 consecutively treated children, 62 boys and 53 girls, were compared with those obtained from a control group of 104 children, 52 boys and 52 girls. Pretreatment radiographs were taken at the deciduous-mixed dentition interphase (T1) and after full eruption of all permanent incisors and first molars (T2). The mean age of the children in both groups was 5.1 years at T1 and 8.4 years at T2. Results: A significant difference between the groups at T2 was found in the mandibular length, midfacial length, and maxillomandibular differential. The increase in mandibular length was 11.1 mm in the treatment group and 7.2 mm in the control group. No differences were found in measurements of maxillary position or size. There was a significant shift toward a Class I relationship in the treatment group. Labial tipping and linear protrusion of the mandibular incisors was evident in the treatment group at T2. There was no effect on the inclination or position of the maxillary incisors. Conclusions: Occlusal correction was achieved mainly through changes in the dentoalveolar region of the mandible. In addition, the appliance enhanced condylar growth resulting in a clinically significant increase in mandibular length. No effect was observed on maxillary position, maxillary size, inclination or protrusion of the maxillary incisors, or facial height.

Background: Early alimentation after caesarean delivery probably has limited clinical significance in terms of improved energy and protein intake. Decreasing the post-operative ileus is possible with early feeding. Objective of this study was to study efficacy of early postoperative feeding versus conventional feeding for patients undergoing caesarean section.Methods: Present study was hospital based comparative study carried out among 200 women who fulfilled the selection criteria. The cases were divided into 2 groups of 100 each by suitable random sampling technique. Group A included 100 cases who were given early feeding within 6 hours of caesarean delivery. Group B included 100 control who were given the feeding after 24 hours of caesarean delivery.Results: The mean duration of postoperative hospital stay in Group A and Group B was 4.59±0.65 and 4.81±0.81 days respectively (p <0.05). The mean time to return of bowel sounds in Group A and Group B was 2.79±1.36 and 3.55±1.49 hours respectively (p <0.01). 2(2%) cases in group A had postoperative ileus symptoms, whereas 3 (3%) cases in Group B had the same. Statistically significant difference (p <0.05) was seen in terms of vomiting 1% versus 17%, nausea 5% versus 16%, abdominal distention 2% versus 7%, diarrhea 4% versus 90% in the early feeding versus conventional feeding groups.Conclusions: It can be concluded from present study that fast return to the normal diet is possible with early feeding among women undergoing cesarean section compared to the conventional feeding among women undergoing cesarean section.

Background: Laparotomy is most commonly performed under general anesthesia, but spinal anesthesia (SA) is considered an alternative to in the context of limited resources. The safety and efficacy of using SA as substitute for general anesthesia(GA) has not been explored in Afghanistan. Methodology: We conductedan observational study in the general surgery department of Isteqlal hospital in Kabul, Afghanistan on 196 adult patients undergoing emergency laparotomy under spinal anesthesia betweenApril 2018-April 2020. Results: The mean age of patients was 41.5 years (SD=19.4), the ratio of males to females was 1.9:1 and almost half (44.4%) had comorbidities. 21% were classified as ASA grade III and IV with a similar pattern among males and females. A total of 11 (5.6%) cases were converted to GA. Conversion pattern to GA was similar amongmales and females(P=0.71), ASA grade (P=0.432) and age group (P=0.642). The mean length of stay after operation was 6.5 days (SD=4.1). 32 (16.3%) patients suffered SA complications with no significant difference in terms of sex (P=0.134). Hypotension and headache accounted for 97% of complications. Complication rates were similar in terms of intervertebral level (P=0.349), type of abdominal incision (P>0.1) and average length of stay (P=0.156). 18 patients (9.2%) died due to MOF, sepsis, respiratory failure, thromboembolism and cardiogenic shock. Conclusion: Spinal anesthesia is considered a safe and effective anesthesia for emergency laparotomies, even for those with comorbidities. Based on our findings we would recommend spinal anesthesia as an alternative to general anesthesiain emergency laparotomy in Afghanistan.

Abstract Eye-tracking to evaluate gaze patterns has developed as an assessment tool for children with Autism Spectrum Disorder (ASD). Gazefinder is one of Eye-tracking devices and few studies have investigated whether it can measure the gaze data of infants under 12 months of age. We conducted a prospective observational study from April 2019 to March 2020 in a periodic health checkup in Ohchi County, Shimane, Japan. Participants included infants between 4 and 11 months of age who were not suspected the presence of developmental problems. Ninety-three participants’ datapoints were analyzed. The mean age was 6.5 months and mean developmental quotient was 88%. The mean fixation time percentage of all sequences was 81.0% (standard deviation; 4.4), and there was no significant difference in each age group. Infants in all groups showed a significantly higher predilection for eyes than for mouths. There was a positive association of age with human gaze and a negative association with geometric gaze. Moreover, we confirmed that joint attention skills were enhanced in accordance with their growth process. The eye-tracking data were almost corresponding to previous studies’ data of infant with typical development and Gazefinder could be applied to infants starting at 4 months of age.
