Authors: Chifu Irina , Gerstl Amelie , Lengenfelder Björn , Schmitt Dominik , Nagler Nils , Fassnacht Martin , Weismann Dirk 
Published: February 2021

Objective
Treatment of symptomatic hyponatremia is not well established. The European guidelines recommend bolus-wise administration of 150 mL of 3% hypertonic saline. This recommendation is, however, based on low level of evidence.

Design
Observational study.

Methods
Sixty-two consecutive hyponatremic patients admitted to the emergency department or intensive care unit of the University Hospital Wuerzburg were divided in subgroups according to treatment (150 mL bolus of 3% hypertonic saline or conventional treatment) and symptom severity. Treatment target was defined as an increase in serum sodium by 5–10 mEq/L within first 24 h and maximum 8 mEq/L during subsequent 24 h.

Results
Thirty-three out of sixty-two patients (53%) were presented with moderate symptoms and 29/62 (47%) with severe symptoms. Thirty-six were treated with hypertonic saline and 26 conventionally. In the hypertonic saline group, serum sodium increased from 116 ± 7 to 123 ± 6 (24 h) and 127 ± 6 mEq/L (48 h) and from 121 ± 6 to 126 ± 5 and 129 ± 4 mEq/L in the conventional group, respectively. Overcorrection at 24 h occurred more frequent in patients with severe symptoms than with moderate symptoms (38% vs 6%, P < 0.05). Diuresis correlated positively with the degree of sodium overcorrection at 24 h (r = 0.6, P < 0.01). Conventional therapies exposed patients to higher degrees of sodium fluctuations and an increased risk for insufficient sodium correction at 24 h compared to hypertonic saline (RR: 2.8, 95% CI: 1.4–5.5).

Conclusion
Sodium increase was more constant with hypertonic saline, but overcorrection rate was high, especially in severely symptomatic patients. Reducing bolus-volume and reevaluation before repeating bolus infusion might prevent overcorrection. Symptoms caused by hypovolemia can be misinterpreted as severely symptomatic hyponatremia and diuresis should be monitored.

Published: February 2021

Relevance. Recent studies show that even with damage to the structures of the triangular fibrocartilaginous complex (primary stabilizer), instability of the distal ray-elbow joint does not develop in some cases. Studies carried out by a number of authors prove that the distal interosseous membrane of the forearm can influence the stability of the joint and be a secondary stabilizer for it.
Aim of the study. To study the variability in the structure of the distal interosseous membrane of the forearm using anatomical material and determine the effect of the distal interosseous membrane on the stability of the distal ray-elbow joint. Using ultrasound to determine the variability of the structure of the distal interosseous membrane of the forearm.
Materials and methods. Material for our study was 10 pairs of anatomical specimens of the upper extremities. The functional viability was assessed by passive rotation of the anatomical material of the forearm. Changes in the tension of the distal interosseous membrane, its additional formations and the capsule of the distal ray-elbow joint were observed. Ultrasound was chosen as an instrumental method for visualizing the distal interosseous membrane of the forearm and its structures. In the course of this work, 30 volunteers of both sexes and different ages were examined. The study was carried out: maximum pronation (position of the sensor back) and maximum supination (position of the sensor palmar).
Results. In the course of the anatomical study, we determined that in 6 pairs of anatomical material, the distal interosseous membrane is a thin transparent connective tissue structure. No additional formations in the form of thickening were found. In 4 pairs of preparations, which amounted to 40% of the total amount in the distal interosseous membrane, there were additional formations in the form of thickening of the membrane this is the distal oblique bundle and the distal ray-the ulnar tract. During the functional study, it was revealed that during pronation of the forearm, the distal membrane and dorsal capsule are stretched, which in turn holds the head of the ulna in the sigmoid notch of the radius. After conducting ultrasound, we determined the variability in the structure of the distal interosseous membrane of the forearm. The distal oblique bundle is visualized as a linear hyperechoic formation. Of the 30 surveyed, this formation was identified in 13 women (92.8%) and 1 man (7.1%), which in percentage terms was 43%.
Conclusion. After conducting anatomical examination, we determined the variability in the structure of the distal interosseous membrane of the forearm in the form of the presence of thickenings the distal oblique bundle and the distal ray-ulnar tract, and determined the effect of these structures on the stability of the distal ray-elbow joint. An ultrasound scan also identified the features in the structure of the distal interosseous membrane in the form of hyperechoic formation.

Background: A range of surgical techniques are used for perineal wound closure following Abdominoperineal Excision of the Rectum (APER). The aim of this study was to assess the safety and effectiveness of using a biological mesh for perineal wound closure and to compare the outcomes following conventional suture and mesh closure of the perineal wound.Methods: A single-centre retrospective study of a cohort of patients undergoing surgery for low rectal cancer between January 2013 and December 2018. Patient records were analysed for outcomes including perineal complication rates, length of hospital stay and impact of patient factors on complication rates in mesh vs no mesh group.Results: Of the total 43 patients included in the study, 13 (30%) had a conventional perineal closure whereas 30 patients (70%) had a biological mesh reconstruction. Early perineal wound complications were seen in 21/43 (49%) patients. Of those, 6 (29%) patients were in the no mesh group compared to 15 (71%) patients in the mesh group (p = 0.81). 84% of the patients who received neo adjuvant radiotherapy (NART) developed perineal wound infection. There was no statistically significant difference in the mesh and no mesh groups. None of the patient factors, other than preoperative anaemia, had a statistically significant association with the rate of complications in either of the groups.Conclusions: There was no statistically significant difference in the complication rate between primary and biological mesh closure. Biological mesh is safe for perineal reconstruction following APER.

Background: It is known that HIV infection is a risk factor for hearing loss. Therefore this study is to determine the pattern and severity of hearing loss and whether there is a correlation between the CD4 count and hearing impairment in the HIV positive adult patients seen in the infectious outpatient clinic of university of Port Harcourt teaching hospital (UPTH).Methods: A hospital based descriptive cross sectional study of consecutive patients that are HIV positive seen in the infectious outpatient clinic of UPTH within a period of three months, from May to July of 2020. The biodata, history of hearing difficulties and management of the disease was obtained using a semi structured questionnaire. All the patients had otoscopy done and hearing assessment with pure tone audiometry (PTA). The analysis was done with the SPSS version 25 software at a 95% confidence interval and a p value less than 0.05 was considered significant.Results: The study involved 234 subjects comprising 127 males and 107 females. Hearing impairment was seen in n=113 (48.29%). The patients with CD4 count less than 500 cells/mm2 was found to have more hearing loss; 55.8% than those with counts greater than 500 cells/mm2. Age distribution was statistically significant with a p=0.0001.Conclusions: The pure tone audiometric pattern in the majority of the studied population was more of CHL. The age, duration of ARVT and the CD4 count all had statistically significant association with hearing loss in the HIV positive adults.

Authors: Deshmukh Utkarsh , Mehta Rishi 
Published: February 2021

Background: Among the refractive errors, myopia is the most common in school children. Due to myopia, school children are unable to see the blackboard which severely affects their performance. Moreover, they are unable to play outdoor sports thereby hampering their all-round development.Methods: This is a cross-sectional observational and analytical study. All children from 5-12 years attending eye OPD were included. Detailed history was taken and complete ophthalmic examination was done. Low myopia was defined as refractive error of -0.25D to -3D. Moderate myopia was defined refractive error of -3.25 D to -6 D. High myopia was defined as refractive error of ≥-6D. The children were divided into 3 groups according to their age (in years): group-1 (5-7), group-2 (8-9) and group-3 (10-12). The data obtained was subjected to statistical analysis using IBM SPSS version 24. P value was calculated by chi-square test. P<0.05 was considered statistically significant.Results: 153 children were examined, out of which 72 (47.1%) were males and 81 (52.9%) were females. Group-1, group-2 and group-3 had 38, 38, 77 children respectively. Out of 153 children, 26 (16.99%) were found to be myopic. Out of 26 myopic children, males were 11 (42.3%) and females were 15 (57.69%) (p>0.05), Low, moderate and high myopia was found in 19 (73.07%), 6 (23.07%) and 1 (3.84%) child respectively.Conclusions: The prevalence of myopia in school children is 16.99%. There is a need for regular screening of school children to diagnose myopia in them. The limitation of this study is hospital based and small sample size. So, we recommend a community-based study with a larger sample size.

Authors: Selvarajan Rajasekar 
Published: February 2021

Background: Open appendectomy is practiced for more than a century and in the recent times small incision appendectomy is also practiced frequently. The efficacy of conventional appendectomy and small incision appendectomy in terms of pain, operating time and duration of hospital stay and have produced conflicting results. Hence this study was conducted to assess the same. Methods: A hospital based randomized controlled trial study was conducted among the patients with appendicitis undergoing surgical intervention for the same in department of general surgery in Sri Muthukumaran Medical College Hospital and Research Institute, Chennai, during the study period from January 2017 to December 2019. A total of eighty cases with acute appendicitis were included in the study. Group A (n=40) includes conventional open appendectomy cases and group B (n=40) includes small incision open appendectomy cases. Data entry was done using Microsoft excel and data was analyzed using SPSS version 17. Results: Blood loss, post-operative pain scores on day 1 and day 2, duration of hospital stay were found to be reduced in Small incision open appendectomy group compared to conventional open appendectomy group. Duration taken to resuming the normal activities and the complications were found to be similar in both conventional and small incision appendectomy group and small incision open appendectomy group. Conclusions: Small incision open appendectomy is superior to conventional open appendectomy in terms of length of hospital stay, return to normal activity, blood loss and postoperative pain scores, which are considered the major advantages of minimally invasive surgery.

Authors: Durgesh N. Siva , Teja V. Viswa 
Published: February 2021

Background: Cholecystitis can be divided into simple and severe cholecystitis. Untreated simple cholecystitis resolves within 7–10 days if it does not progress to more severe cholecystitis. Aims and objectives were to evaluate whether neutrophil-to-lymphocyte ratio can differentiate between simple cholecystitis and severe cholecystitis. To evaluate role of NLR as a prognostic indicator.Methods: The source of data for our study will be patients admitted in the department of general surgery diagnosed with acute cholecystitis in Konaseema Institute of medical sciences and research foundation, Amalapuram. All patients between 15 to 70 years of age with a clinical diagnosis of acute cholecystitis confirmed with histopathology study. Results: With an NLR value of 4.35, the sensitivity and specificity were 67% and 87%, respectively. Therefore, we considered 4.35 as the cutoff value, and divided the patient population into two groups: those with preoperative NLR values below 4.35 (n=50) and those with values equal to or greater than 4.35 (n=15). 53.33% of higher NLR group patients had severe cholecystitis compared to only 8 % of patients in lower NLR group (p<0.05). Conclusions: It was seen that the patients with cholecystitis can be divided into low risk (NLR<4.35) and high risk (NLR≥4.35) groups for severe cholecystitis as per the NLR value at admission.
Rolling Bearing Fault Diagnosis based on Residual Neural Network
Authors: Liang Haopeng 
Published: February 2021

<div class="Section0"><div>Because rolling bearings have been working in an environment with complex and variable working conditions and large noise interference for a long time, the bearing fault diagnosis method has a poor diagnostic effect under variable working conditions. To solve this problem, we propose a residual neural network based on the diagnosis method of rolling bearing fault. The proposed method takes rolling bearing time-domain signal data as input. Because bearing signals have strong time-varying properties, we construct a multi-scale residual block that can not only learn features at different levels, but also expand the width and depth of the residual neural network. We use the advantages of the dilated convolution to expand the receptive field, replace part of the ordinary convolution in the multi-scale residual block with the dilated convolution, and design a multi-scale hollow residual block. The advantage is that the method is made by expanding the receptive field. It has a strong feature learning ability and can learn better features under limited data. Finally, we add a Dropout layer to discard a certain proportion of neurons after the fully connected layer, which can effectively avoid the negative impact of overfitting, and use Case Western Reserve University bearing dataset, the simulation experiment, and the SVM + EMD + Hilbert envelope spectrum, BPNN + EMD + Hilbert envelope spectrum and Resnet three ways of comparative analysis, the results show that the method under the variable condition of the fault diagnosis of rolling bearing has higher diagnosis accuracy, stronger noise resistance, and generalization ability.</div><p> </p></div><p> </p>
