Bend Angles

Abstract Background For successful lighted stylet intubation, bending the lighted stylet with an appropriate angle is a prerequisite. The purpose of this study was to compare three different bend angles of 70, 80, and 90 degrees for lighted stylet intubation. Methods The patient trachea was intubated with a lighted stylet bent at 70, 80, or 90 degrees according to the randomly allocated groups (group I, II, and III, respectively). A lighted stylet combined with a tracheal tube was prepared with a bend angle of 70, 80, or 90 degrees according to the assigned group. We checked the success rate at the first attempt and overall success rate for the two attempts. Additionally, we measured search time, which was time from insertion of the bent union into the patient mouth to the start of advancing the tracheal tube while separating it from the lighted stylet, and evaluated postoperative sore throat (POST) at 2, 4, and 24 h after the recovery from anesthesia. Results There was no statistically significant difference between group I, II, and III for success rate at first attempt (73.9 %, 88.2 %, and 94.7 %, respectively, p = 0.178), even though there was a trend of increasing success rate with increasing bend angles. For overall success rate, there was similar result to that in the first attempt between the groups I, II, and III (82.6 %, 94.1 %, and 100 %, respectively, p = 0.141). However, search time took significantly longer in group I than groups II and III (p < 0.001). When group II and III were compared for POST with numeric rating scale (0–10), it was significantly lower in group II than III at 2, 4 h after the recovery (0.5 vs. 2.3, p = 0.016, and 0.4 vs. 1.8, p = 0.011, respectively). Conclusions The bend angle of the lighted stylet affected the time required for tracheal intubation and POST in our study. 80 and 90 degrees as a bend angle seem to be acceptable for clinicians in regard to success rate of lighted stylet intubation. Considering the success rate of lighted stylet intubation and POST, the bend angle of 80 degrees might be better than 70 and 90 degrees.

Abstract ADHD is one of the most common neurobehavioral disorders among children and adolescents. In this prospective study, we aimed to measure circulating zinc and ferritin levels in children with ADHD, pick up the deficient ones to give zinc and iron supplements then compare before and after treatment according to their Conner’s scores and Wecsler IQ test. Current study included fifty children diagnosed as having ADHD by DSMV criteria, their zinc and ferritin levels were measured by Colorimetric method and enzyme-linked immunosorbent assay (ELISA) respectively. They were divided into: group I (zinc only deficient),group II (zinc and ferritin deficient),group III (non-deficient), cases with mineral deficiency received zinc (55 mg/day) and/or iron (6 mg/kg/day) for 6 months then reassessed by parent Conner’s rating scale. In group 1, there was no significant difference between the Wecsler verbal and non-verbal IQ scores and oppositional and cognitive problems in Conner’s scores before and after zinc supplements, although there was significant improvement in attention, hyperactivity, emotional liability and impulsivity. In group II, there was significant improvement in verbal and total IQ but not in performance IQ, also there was significant improvement in hyperactivity, emotional liability and impulsivity with no significant difference in oppositional, cognitive problems and inattention before and after zinc/ iron supplements. In Conclusion, Zinc supplements in adjuvant to the main treatment significantly improved symptoms of ADHD children. However, a combined zinc and iron supplements was superior to zinc alone in alleviating ADHD symptoms as well as IQ improvement.

Background: The application of yoga as a therapeutic intervention, which began early in the twentieth century, takes advantage of the various psychophysiological benefits of the component practices. The physical exercises (asanas) may increase patient’s physical flexibility, coordination, and strength, while the breathing practices and meditation may calm and focus the mind to develop greater awareness and diminish anxiety, and thus result in higher quality of life. The present study was conducted to evaluate the effectiveness of Yoga in patients with functional psychotic disorder. Materials & Methods: 100 patients with a diagnosis of functional non-affective psychosis were involved in the study. They were divided into 2 groups. Group I (Yoga) – It included 50 patients. Group II (Exercise)- It included 50 patients. The severity of clinical state was measured on Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale (HDRS) and Clinical Global Impression Severity (CGIS). Assessment was performed at the time of starting yoga/exercise as well as 2 and 6 weeks thereafter. At these 3 time points, the extra pyramidal (Parkinsonian) side-effects too were measured using Simpson Angus Scale (SAS). Results: Group I had 25 males and 25 females. Similarly group II had 25 males and 25 females. The difference was non significant (P – 1). College literate in group I was 15, in group II was 9. 22 patients and 23 patients were on second generation antipsychotics in group I and group II respectively. Illness duration was 20.4 years and 24.2 years in group I and group II respectively. Positive syndrome score was 19.2 and 19.1 in group I and group II respectively. Negative syndrome score was 16.8 and 17.1 in group I and group II respectively. General psychopathology score was 25.4 and 26.2 in group I and group II respectively. Total HDRS score was 61.8 and 61.2 in group I and group II respectively. Total HDRS Score was 13.8 and 14.2 in group I and group II respectively. Total SAS score was 3.2 and 3.4 years in group I and group II respectively. The difference was non significant (P > 0.05). CGI illness severity score in group I, at baseline, 2weeks and 6 weeks was 6.04, 4.65 and 3.12 respectively. Similarly in group II, it was 6.18, 5.14 and 3.86 at baseline, 2weeks and 6 weeks respectively. The difference was significant (P < 0.05). Positive syndrome score in group I, at baseline, 2 weeks and 6 weeks was 18.98, 13.84 and 7.8 respectively. Similarly in group II, it was 18.5, 14.82 and 9.22 at baseline, 2 weeks and 6 weeks respectively. The difference was significant (P < 0.05). Negative syndrome score was significantly higher at 6 weeks in group II as compared to group I (P < 0.05). General Psychopathology score was statistical significant at 2 weeks (P < 0.05). Total PANSS score was statistical significant at 2 weeks (P < 0.05). There was statistical significant difference (P < 0.05) in HDRSS score in both groups. At 2 weeks the total SAS score was statistical significant among both groups (P <0.05). Conclusion: Yoga may be beneficial in patients with psychotic disorder. This has additional advantage along with standard pharmacological management.

Objective: To evaluate the outcome of Vesico-vaginal Fistulae (VVF) repair by abdominal and vaginal route. Design: Interventional / clinical trial. Setting: Department of Urology, Chandka Medical College Teaching Hospital and Almas Medical Centre Larkana. Period: Feb; 2005 to Nov; 2010. Patients/Methods: After routine clinical examination and investigation, patients having Vesico-vaginal Fistulae (VVF) were selected for repair. All patients had under gone examination those anesthesia (EUA) and cystoscopy. The patients having complex fistulae or associated with urethral, ureteric and colonic involvement or with preexisting malignant pelvic pathology were excluded from the study. Patients were divided in to 02 groups on the basis of the site of the fistula and the method of repair. Group-I comprised of those patients who had low type or uncomplicated fistulae and were operated by vaginal approach. Group-II consisted of those patients who had high type or large fistulae and were operated by abdominal approach. Postoperative follow up was carried out on weekly basis for 03 to 06 months. Results: Our study included 32 cases. Group-I and II comprised of 18 and 14 patients respectively. The mean age was 34 years (ranged from 22 to 45 years). The main cause of vesico-vaginal fistulae was obstetrical in 28(87.5%) and iatrogenic gynecological (hysterectomy) in 04 (12.5%) patients. No major difficulty was experienced except in 01(0.83%) case in group-1 who had a previous failure history of repair. The mean operative time was 95 minutes (range 80 to 125 minutes) & 145 minutes (range 110 to 175 minutes) in group-1 and group-2 respectively. Peroperative blood transfusion was required in 06 (33.33%) and 13 (93%) patients of group-1 and group-II respectively. Statistically significant difference was found between these two groups (P< 0.05). Postoperative complications like wound infection occurred in 01(7.15%) of group- 1 and haematuria was present for few days in o4 (22.22%) and 05(35.5%) in group-1 and group-2 respectively. The mean hospital stay was 07 (range 5-10) days. Foleys catheter was removed at 02 week time in all cases. The success rate was achieved 15(83.33%) and in all 14 (100%) cases for group-1 and group-2 respectively and statistically no significant difference was found between two groups (P=NS). All the patients were followed up regularly except 03 (16.5%) and 05 (35.5%) patients of group-1 and group-II respectively. Long term complications like urinary stress incontinence was observed in 2 (11.1%) patients of group-I, where as small capacity bladder and stone formation was observed in 02(14.3%) of group-11 cases. Conclusions: Birth trauma is still a major cause of vesico vaginal fistula in our region. Although, there is no significant difference in outcome of different technique but interposition of tissue between suture lines have a vital role to achieve a high success rate. Further more, best chance of success achieved with first attempt of repair. Strategic approach and proper training of medical and paramedical staff is recommended.

Introduction Tonsillectomy is one of the most commonly performed surgical procedures worldwide, with the major drawback of significant post operative pain.There is no consensus regarding topical application or local infiltration of anesthetics post operatively to reduce pain. The present study was performed to evaluate the effect of bupivacaine infiltration in the tonsillar fossae after tonsillectomy. Materials and Methods A double-blinded clinical trial was performed on 75 patients undergoing tonsillectomy between January 2019 and January 2020. All patients underwent tonsillectomy under general anesthesia and were then randomly divided into 3 groups of 25 patients each. For Group I, a swab soaked in normal saline was applied to the tonsillar fossae for 5 minutes just before extubation. In Group II, a swab soaked in 5 ml of 0.5% bupivacaine was placed for 5 minutes, while in Group III, 5ml of 0.5% bupivacaine was infiltrated in the tonsillar fossae. The intensity of pain for each group was measured in the immediate post op period, at6 hours, 24 hours and 1 week by Wong Baker Faces Pain Rating Scale. Results There was a significant difference in the mean level of pain between groups I and III in the immediate post op period, at 6 hours and 24 hours. Although the average pain scores of group III were better than those of group II, the results were significant only in the 6 hour post op period. Conclusion To reduce post-tonsillectomy pain,0.5% bupivacaine can be infiltrated into the tonsillar fossa.

Abstract Background Hemodialysis may have serious psychological impact upon patients suffering from chronic kidney diseases. The aim of the present study is to investigate the impact of hemodialysis on the wellbeing of individuals with chronic kidney diseases (CKD). Result A sample consists of (N = 100) CKD patients referred from neurology ward of Leady Reading Hospital Peshawar. Data was collected from both male (50%) and female (50%) in 2017. Participants were divided into two groups on the basis of pre-set criteria. In group I, individuals with 4–5 stage of CKD referred first time for dialysis treatment were recruited. Group II comprised of CKD patients with 1–3 stage. Demographic data sheet, Pakistan Anxiety and Depression, WHO Quality of Life scale, and Perceived Social support scale (PSS) were used to test the hypotheses. Paired sample t test was use to see the difference between pre- and post-analysis of depression, anxiety, QOL, and PSS in group I (experimental group). Results suggests significant difference on depression (p > .001), anxiety (p > .001), and QOL (p > .001), while no significant difference was reported on perceived social support (p <.673). Findings also indicate no significant difference between group I and group II on QOL depression, anxiety, and PSS. Conclusion The findings concluded that patients under hemodialysis treatment suffered from depression, anxiety, and poor quality of life.

Objective This study aimed to assess whether cord blood carboxyhemoglobin (COHb) levels in jaundiced term neonates with and without a positive direct Coombs test (DCT) and in healthy controls could be used as a predictor of severe hyperbilirubinemia. The percentage of cord blood COHb should be higher among neonates with Coombs-positive ABO hemolytic disease than among those with Coombs-negative ABO incompatibility and higher than that of ABO-compatible control neonates. Study Design This cross-sectional descriptive study of 198 term neonates comprised three subgroups: group I featured 68 DCT-positive ABO-incompatible neonates (ABO + DCT), group II featured 60 DCT-negative ABO-incompatible neonates with hyperbilirubinemia (ABO–DCT), and group III featured 70 healthy controls. COHb was determined by an OSM3 hemoximeter. Results Group I differed from groups II and III for cord blood bilirubin, cord blood hemoglobin, and cord blood hematocrit. Groups I and II had higher mean total serum bilirubin (TSB) levels than group III, while there was no difference in the mean TSB levels between groups I and II. There was no significant difference between the COHb group means for groups I, II, and III (p = 0.98). The area under the receiver operating characteristic curve calculated for group I/group III and group II/group III were found to be 0.62 and 0.54, respectively. Conclusion COHb levels did not prove to be superior to the DCT for predicting the risk of developing severe hyperbilirubinemia in term neonates. Key Points

The significant difference between recycled aggregate and natural aggregate is the content of the attached mortar layer. With the increase of the replacement rate of recycled aggregate, the shrinkage and creep of recycled aggregate concrete is significantly increased. In this paper, 180-day shrinkage and creep tests of recycled aggregate concrete with different water–cement ratios were designed in order to analyze the effect of the substitution rate and water–cement ratio on shrinkage and creep properties. The results show that the shrinkage strain of recycled aggregate concrete with a substitution rate of 50% and 100% at 180 days is 26% and 48% higher than that of ordinary concrete, respectively, and the growth of group II is 22% and 47%, respectively. When the load was 180 days old, the creep coefficient of recycled aggregate concrete with a substitution rate of 50% and 100% in group I increased by 19.6% and 39.6%, respectively compared with ordinary concrete, and group II increased by 23.6% and 44.3%, respectively. Based on the difference of adhering mortar content, the creeping increase coefficient and shrinkage increase coefficient of the attached mortar were proposed, and a shrinkage and creep model of recycled aggregate concrete was established. When compared with the experimental results, the model calculation results met the accuracy requirements.

Objective. Ectopic pregnancy adversely affects the patency of the fallopian tube and consequently the future pregnancy. There are different options of conservative treatment of tubal pregnancy such as methotrexate and salpingostomy [1]. There is little information on the success rate of maintaining tubal patency after methotrexate and salpingostomy [2]. Therefore, the aim of this study is to evaluate the ipsilateral tubal patency using HyCoSy after treatment of tubal pregnancy with methotrexate therapy versus salpingostomy. Patients and methods. This was a case-series study conducted in Ain Shams and Al-Azhar University Maternity Hospitals to evaluate the ipsilateral tubal patency using hysterosalpingo-contrast sonography (HyC0Sy) following salpingostomy and medical treatment of tubal pregnancy. This study included patients who were admitted to Ain Shams and Al-Azhar University Maternity Hospitals for having tubal pregnancy and were treated either with methotrexate or salpingostomy over a 4-year period between January 2017 and December 2020. The patients seeking fertility were re-evaluated for fallopian tubes patency by hysterosalpingogram 3 months after discharge. The study included 2 groups of women: group I (n = 200): women who were treated with methotrexate, and group II (n = 140): women who underwent salpingostomy. Results. HSG was performed in 200 cases of patients with tubal pregnancy who were treated with methotrexate and 140 cases of patients who underwent salpingostomy. The patency of the ipsilateral tube was 85% after methotrexate treatment and 84.2% after salpingostomy. There was no statistically significant difference between the two groups. Conclusion. The findings suggest similar success rate in maintaining the patency of the fallopian tube with either methotrexate or salpingostomy. Key words: ectopic pregnancy, hysterosalpingography, methotrexate, infertility, salpingostomy

Objective: To evaluate the efficacy of immersive VR (IVR) and non-immersive VR (NIVR) distraction on perceived pain during intraoral injections in children undergoing dental procedures. The objective was to introduce 3-dimensional nature of virtual reality during the provoking phase of dental treatment as a means of distraction in children. Study design: A total of 200 children were selected for the study, 100 for IVR group and 100 for NIVR group. After randomization, children were introduced to Oculus Go Standalone equipment; MCDAS (f), VAS, WBFRS and the treatment procedure using tell show do technique. Group I children were introduced to oculus go standalone headset with hand held controller to play temple run or roller coaster game while in group II, children watched cartoon movies of their choice. Pre-operative & post-operative MCDAS scores were obtained using MCDAS (f) questionnaire in local language. Post-operatively, VAS and WBFRS scores were also obtained. The data was analyzed using independent t-test and chi-square analysis. Results: Pre-operatively, the mean MCDAS scores were similar in both the groups viz. Group–I (29.20 ± 3.197) and Group–II (29.09 ± 3.803) and is statistically not significant. Post-operatively, the mean MCDAS scores were higher in non-immersive group (20.72 ± 2.822) as compared to immersive group (10.99 ± 2.227). VAS score was higher in non-immersive group (2.72 ± 0.99) as compared to immersive group (0.75 ± 0.88). WBFRS scores were higher in non-immersive group (2.78 ± 1.097) as compared to immersive group (0.82 ± 1.104). Conclusion: Three-dimensional virtual reality was found to be an effective means of distraction in children undergoing dental procedures and especially during the provoking phase. The significant difference obtained clearly indicates irrespective of immersiveness of virtual reality, anxiety had been decreased and on comparison the pain perception to intraoral injection is less in immersive virtual reality environment. Immersive VR distraction technique can serve as an adjunct to traditional behavior management strategies already available to the pediatric dentist.
