Authors: Pontoh Valentini Mega , Purnami Nyilo
Published: March 2022

Background:

Rubella is caused by the rubella virus that transmits through droplets or direct contact that can cause congenital defects such as hearing loss. Immunoglobulin M (IgM) rubella can be detected in infants under 1 year of age with suspected congenital rubella syndrome (CRS).

Objectives:

This study was to analyze the correlation between hearing loss with IgM rubella in infants.

Methods:

This was an observational analytic study with a retrospective in infants <1 year of age with suspected CRS. Medical records and CRS surveillance data of subjects who came to the Otorhinolaryngology Outpatient Clinic, Dr. Soetomo Hospital, Surabaya, from January 1, 2015, to December 31, 2017, were collected. The data were grouped based on age, gender, place of residence, clinical symptoms, hearing examination (otoacoustic emission and automated auditory brainstem response), IgM and IgG examination, and CRS classification.

Results:

Total patients were 171 patients with the highest number of patients was the 0-3 years age group as many as 136 patients (79.5%) and girls patient more than boys as many as 88 patients (51.5%). The most clinical symptom of CRS was 24-hr postpartum jaundice were 111 patients (74.4%). The serological Rubella IgG were positive results with a total patient were 140 (81.9%) and Rubella IgM results were negative with 141 (82.5%). The most CRS case criteria were non-CRS with 78 patients (45.6%). There was correlation of hearing loss with IgM rubella in infants <1-year with suspected CRS and statistical results p= 0.03.

Conclusion:

IgM rubella correlates to clinical symptoms of hearing loss in infants <1 year of age with suspected CRS.

Authors: Aryal Sajana , Prabhu Prashanth
Published: March 2022

Ramsay Hunt syndrome (RHS) Type II is characterized by facial paralysis, herpetic eruptions on the auricle/mouth, and otic pain due to reactivation of the latent varicella-zoster virus in the geniculate ganglion. A typical case of RHS with multicranial nerve involvement is a rare disorder and more severe than without such involvement. In this case study, we report a case of a 54-year-old man with multicranial nerve involvement. The combined treatment with medicines (corticosteroids and antiviral drugs) and rehabilitation therapy has been partially successful but did not completely resolve facial palsy and hearing loss.

Authors: Polson Ann Maria , Menon Unnikrishnan K. , Prem G. , Kumar M. , Bhaskaran R.
Published: March 2022

Context:

There is a need for a quick reliable home test for detecting hearing loss (HL), especially in the present era of telemedicine. Hum test is one such which can be performed easily without instruments but not much documented in the literature.

Aims:

The aim is to find out the diagnostic accuracy of hum test in detecting unilateral HL.

Settings and Design:

Tertiary healthcare center, prospective, cross-sectional diagnostic test accuracy study.

Subjects and Methods:

The study included 85 controls and 85 patients with unilateral conductive or sensorineural HL (SNHL). The patients were divided into four groups-controls, simulated unilateral conductive HL (CHL) subjects, unilateral CHL, and SNHL patients. They underwent 4 tests-Weber test, Low pitch hum test, High pitch hum test, and pure-tone audiometry (PTA), the latter being the gold standard.

Statistical Analysis Used:

To test the statistical significance of the agreement between the hum test and the Weber test with PTA, McNemar's Chi-square test was used. Diagnostic measures such as sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were computed.

Results:

The sensitivity (85%) and accuracy (95.2%) of Hum test were better in comparison to Weber test (70% and 88.8% respectively) in unilateral sensorineural patients. However, in the case of CHL the Weber test was more sensitive in comparison with hum test (95.6% and 83.35% respectively). Overall, the diagnostic accuracy of hum test was 92.5% when compared to the Weber test (93.5%).

Conclusions:

Hum test can be used as a reliable screening tool for suspected sudden HL cases.

Authors: Ahiwale Prashant Prakash , Singla Bhavika , Shetti Akshaya N. , Mustilwar Rachita G
Published: March 2022

Introduction:

Anesthesiologist plays an important role in intensive care units, trauma centers, pain clinics, and as a member of resuscitation team all over the world. Due to the lack of public awareness about anesthesia as a medical discipline, many patients assume an anesthesiologist to be an assistant of the surgeon and do not recognize the role played by the anesthesiologist in preoperative, perioperative, and postoperative periods. With the changing health-care environment and advancement in anesthesiology, the patients and general public need to be educated.

Aims and Objectives:

This study aimed to assess the knowledge of patients regarding anesthesia and anesthesiologist at rural tertiary care hospital.

Design:

This is a descriptive cross-sectional study done at a rural tertiary care hospital.

Materials and Methods:

After approval of the institutional ethical committee, the study was conducted in the form of a questionnaire for patients coming to preanesthetic checkup outpatient department (OPD) for elective surgery.

Results:

This study involves 602 (312 male; 290 females) for preanesthetic checkup OPD, of whom only 403 (67%) of them recognized anesthesiologists as doctors, while 401 (66.7%) knew that anesthesia is required prior to any surgical procedure and 209 (41.4%) of them knew anesthetists play a role in intraoperative and postoperative patient care.

Conclusion:

We can conclude that there is unawareness among the rural population regarding the role played by anesthesiologists; hence, initiatives are to be taken for educating the population.

Authors:   Università di Milano Bicocca, Dip.to di Sc. Geologiche e Geotecnologie, Basso Daniela , Vrsaljko Davor ,   Croatian Natural History Museum, Grgasović Tonći ,   Croatian Geological Survey, Zagreb, Croatia
Published: March 2022

The fossil coralline flora of the Badenian bioclastic limestone outcropping in Northern Croatia is known by the name “Litavac”, shortened from “Lithothamnium Limestone”. The name was given to indicate that unidentified coralline algae are the major component. In this first contribution to the knowledge of the coralline flora of the Litavac, Lithothamnion valens seems to be the most common species, with an unattached, branched growth-form. Small rhodoliths composed of Phymatolithon calcareum and Mesophyllum roveretoi also occur. The Badenian benthic association is dominated by melobesioid corallines, thus it can be compared with the modern maërl facies of the Atlantic Ocean and Mediterranean Sea. Since L. valens still survives in the present-day Mediterranean, an analogy between the Badenian Litavac and the living L. valens facies of the Mediterranean is suggested.

Effect on Soil Hydrodynamic Parameters in Fields Mulched with Gravel for Different Periods of Time
Authors: Zhao Wenju , Wang Yali , Li Zongli , Cao Taohong
Published: March 2022

Soil-water characteristic curve (SWCC) and soil hydraulic conductivity are important soil hydrodynamic parameters, which are of great significance in production practice. In 128 soil samples collected from 0-20, 20-40 cm layers at sampling scales of 32×32 m, the authors determined the effect of different periods of time on SWCC and soil hydraulic conductivity in fields mulched gravel. The water holding capacity of soil changes dramatically throughout time, with NEW having the maximum water holding capacity. As the planting time increases, the soil water holding capacity decreases. Both van Genuchten (VG) and Gardner models can fit SWCC in different time periods well, but the fitting accuracy of the VG model is higher. Geostatistics and Kriging interpolation are used to study the spatial variability of the VG model parameters of the SWCCs. The parameters θs, α, and n show a strong spatial correlation as a whole and are slightly affected by random factors. The changing trend of soil unsaturated hydraulic conductivity (K(θ)) in gravel-mulched fields is faster than the CHECK, and the NEW has the fastest change trend. The data suggest that fields mulched with gravel retain more water, with the NEW having the most noticeable water retention effect. The study’s findings can be used to investigate the regional variations in soil hydrodynamic characteristics in gravel mulched fields in arid locations.

Published: March 2022

This study mainly aims to detect the county-level spatio-temporal variability of LULCC (Land Use and Land Cover Change) spatial patterns in Southwest China. Multi-temporal Remote Sensing (RS) images (Landsat TM/OLI in 2000, 2005, 2010, and 2015) were applied to extract land use/cover types at each of the four-time nodes using the Support Vector Machine (SVM) method. Then, the trajectory map methodology was adopted to identify the spatio-temporal distribution characteristics of LULCC patterns throughout the given time series. According to the results, the area of unused land decreased continuously, 0.094% total. An evident decline of grassland by 2.17% was documented, and a notable increase was observed in forestland by 63.94 km2 during the period from 2000 to 2015. Water bodies, built-up land, and unused land showed no significant change throughout the study period. The conversion from grassland to forestland and vice-versa (code 13 or 31) was prominent due to an adjustment made to local forestry policy during the first two periods (2000-2005 and 2005-2010), accounting for 17.55% and 17.56% of the study region, respectively. The anaphase trajectory transition type occupied the smallest area of all the trajectory maps. By contrast, the repetitive trajectory was the leading land-use transition type and covered the largest area. Trajectory analysis provides an effective approach for detecting the spatio-temporal changes in LULCC patterns.

Published: March 2022

Background: Urogenital abnormalities are common in patients with anorectal malformations (ARM). The wide spectrum of urogenital abnormalities and ARM sometimes make it difficult to name the conditions simply.
Case Presentation: We experienced a case of penile hypoplasia associated with the urethrorectal communication.
Conclusion: From the viewpoint of urogenital anomalies, we might call this condition “aphallia variant” or “absent penis spectrum”. On the other hand, from the viewpoint of ARM, we might call this condition “male posterior cloaca” or “partial urorectal septum malformation sequence”. More important than naming them is understanding the clinical conditions precisely.

Introduction  
Chronic sinusitis with chronic rhinitis affect the patients’ quality of life significantly. Aim of this study is to assess the outcome of Endoscopic Sinus Surgery (ESS) in terms of Quality of Life (QoL) in patient with Chronic Sinusitis with Chronic Rhinitis (CSCR), non-responsive to medical therapy.
 
 
Materials and Methods
Prospective study was conducted among 75 patients of CSCR non responsive to medical therapy in the age group of 15 to 80 years over a period of 18 months (January 2018 to June 2019). The subjects were randomly grouped into two, namely Group 1- CSCR with Polyp and Group 2- CSCR without Polyp. Subjects were asked to complete SNOT-22 score and Visual analogue scale (VAS) and conventional medical treatment was given for 2 weeks. Those failed to respond as per EPOS guideline were subjected to ESS and followed up at 6 weeks and 12 weeks, re-assessed by SNOT-22 questionnaire and VAS. Data was analyzed by using Paired t- test.
 
Results
Statistically significant (p-value <0.05) improvement in symptom score assessing QoL after Endoscopic sinus surgery.
 
Conclusion
Patients with CRS non- responsive to medical treatment, the decision for surgery should be guided by their pre-operative QoL impairment, as measured by SNOT-22 and VAS.

Authors: Singh Amardeep , Kameshwarachar Manjunath , Singh Harbans
Published: March 2022

Introduction
Morphometric study of sphenoid sinus shows various degrees of pneumatization. Knowledge of such variability is extremely important to guide the surgeon in predicting what type of surgical approach will be safer for the pathologies involving skull base region. Considering recent advances in trans-nasal trans-sphenoidal endoscopic interventions and improved visualization, it has become imperative to become familiar with the anatomical variations which are likely to be encountered during surgical procedures.
 
Materials and Methods
A retrospective study was conducted on the basis of CT scan records of 120 patients to evaluate variability in pneumatization of sphenoid bone and its extensions in South Indian population.
 
Results
The study revealed the prevalence of conchal, pre-sellar, incomplete sellar and complete sellar types of sphenoid pneumatization in 02%, 08%, 28% and 62% cases respectively. Posterior or clival extension was the commonest type seen in 80% cases which included sub-dorsal (50%), dorsal(15%) and occipital(15%) types of clival variants. In lateral extensions, pterygoid sub-type was observed in 37% of patients whereas lesser wing, greater wing and full lateral sub-types were present in 20%, 14% and 09% cases respectively. Various combinations of lateral sub-types were seen in 15% of study population.
Conclusion
In our study higher percentage of pneumatization of sphenoid sinus and its extensions was observed when compared to Egyptian and Chinese populations. High prevalence in South Indian population also provides an additional armament in the hands of surgeon to reach the otherwise unreachable lesions involving middle and posterior cranial fossae through trans-sphenoidal approach.

Authors: Gupta Priyanshi , Singh Rawat Digvijay , Aseri Yogesh , Verma PC , Singh BK
Published: March 2022

Introduction
Allergic Fungal Rhinosinusitis (AFRS) is characterized by an inflammatory response to a non-invasive fungus which leads to sinus obstruction. Ophthalmic manifestations of AFRS are rare but can be of grave consequence.
Case Report
A 22-year-old female patient presented with a 5-day history of headache and decreased vision in both eyes (right- perception of light; left-6/18), along with a past history of nasal blockage and recurrent rhinorrhoea. She had thick viscid mucous secretion with polyposis in bilateral nasal cavities. Computed tomography showed pansinusitis with heterogenous opacification and polypoidal mucosal hypertrophy. Bony erosion was seen in bilateral orbital apices with oedematous optic nerves. MRI was suggestive of bilateral optic neuritis. Patient underwent emergency surgical debridement via endoscopic sinus surgery. Histopathological examination of the specimen showed cellular debris, eosinophilic prominence and numerous Charcot-Leyden crystals, with presence of branched septate fungal hyphae. Fungal culture grew Aspergillus flavus. Patient was treated with steroids (injectable followed by oral in gradually tapering doses). Over a period of 3 months vision returned to normal.
Conclusion
Vision loss is a rare complication of AFRS and constitutes an emergency. Prompt treatment with surgical debridement and corticosteroids is essential for reversal of visual complications.

Published: March 2022

Introduction
Diabetes mellitus cases are increasing worldwide. It affects almost all systems of the body including audio-vestibular system. Diabetic otopathy (DO) is the presence of symptoms and signs of vestibular and auditory disorders in patients with diabetes mellitus after the exclusion of other causes. In this review we aimed to study the mechanism of development of hearing loss in diabetes, the relationship between duration and severity of diabetes, and association of other complications with hearing loss. 
Materials and Methods
We searched the MEDLINE & PubMed database using terms ‘diabetic otopathy’ and ‘diabetes & hearing loss’ for the articles published since 1970. Twenty articles were selected and reviewed.
Results
The mechanism of development of DO is not yet clearly known. But it is suggested to be multifactorial. This review of literature suggested that hearing impairment is two times more prevalent in subjects with diabetes as compared to those without diabetes. The relationship between diabetic otopathy and diabetic kidney disease is most commonly noticed.
Conclusion
The higher prevalence of hearing impairment in diabetic patients compared with nondiabetic patients was consistent. It is necessary to establish a screening and monitoring strategy for patients with diabetes mellitus to prevent the development of hearing loss and its consequences on life quality.

Authors: Patel Jaykumar , Sharma Yojana , Govindarajalu Priyadarshini , Vadiya Sohil
Published: March 2022

Introduction
Epistaxis is the commonest otorhinolaryngological emergency affecting upto 60% of population. The aetiology of epistaxis can be local or systemic. Often it may be difficult to categorize the epistaxis and no clear cause is found; then it is labelled as idiopathic.
Materials and Methods
It was a prospective observational study. All the patients of both gender, age ≥18 years with epistaxis without obvious cause coming to the ENT OPD/ Emergency were included in the study. The patient's vitals were recorded and hemodynamical stability was established first. All patients of epistaxis underwent thorough clinical examination and proper history was taken. Measures to stop bleeding included nasal packing, electro/chemical cautery of local area or ligation of sphenopalatine vessels etc. Efforts were made to establish a primal relationship of adult epistaxis with various factors.
Results
There were 97 patients in the study. Male to female ratio was 5.7:1. Majority were above 40 years. The commonest factor associated with epistaxis was Hypertension(38%) followed by idiopathic(21%). Anterior nasal bleeding was present in 71% patients whereas posterior nasal bleeding was there in 29% patients. Non-surgical measures like nasal packing and cauterization were the main intervention methods. Duration of hospital stay was more than 3 days in 73% patients.
Conclusion
Hypertension, blood thinners and trauma were the most common risk factors among the patients in whom aetiology was found although in 21% of the patients, aetiology could not be found. Most cases were successfully managed with conservative (non-surgical) treatment.

Effects of Aloe woodii gel methanolic extract on the liver function changes induced by high sugar intake in female albino rats
Authors: Al-Khatib Bushra Y. H.
Published: March 2022

Consuming sugar-added foods and sweetened beverages is being a familiar habit associated with many diseases. Folk information in Yemen indicates the therapeutic effects of Aloe woodii on some diseases. So, the aim of this study is to evaluate the ameliorated effect of Aloe woodii gel extract on liver lesions in female rats induced by high table sugar intake. This study lasted 11 weeks and was divided into two periods. The first period was for high table sugar supplement, whereas the second was for the treatment by the methanolic extract of Aloe woodii gel. At the end of the experiment, body weights were recorded, blood samples were taken, and liver samples were also taken for the histopathological examination supported by quantitative measurement. Results: There was no remarked change in the body weights between groups, but there was an accumulation of the visceral fat and an elevated of alanine aminotransferase (ALT) level in the sugar group. Histopathological examination of liver tissues in the sugar group revealed many degenerated manners such as vacuolation and/or ballooning of hepatocytes and inflammation. However, the treatment by Aloe woodii gel led to an ameliorate of the histopathological changes, but had no effect on ALT level. Conclusion: High sugar supplement induced high visceral fat accumulation and many lesions in liver tissue, whereas Aloe woodii treatment ameliorated these effects.

Authors: Khanbari Shada Omer , Haider Adel Sallam M.
Published: March 2022

Breast cancer is the greatest challenging health complexities that medical science is facing. Most cases can be prevented by early detection and diagnosis which are the best way to cure breast cancer to decrease the mortality rate. The aim of this research is to obtain a method for enhancing the mammography images by using the proposed method which is incorporating the Local Contrast with Contrast Limited Adaptive Histogram Equalization (LC-CLAHE) to improve the appearance and to increase the contrast of the image and then de-noised by 2D wiener filter techniques. To extract the region of interest (tumor), we used region growing technique for the segmentation process. The standard Mammographic Image Analysis Society (MIAS) database images are considered for the evaluation. Efficiency is measured by Root Mean Square Error (RMSE) and Peak Signal to Noise Ratio (PSNR). It is observed that the proposed method with wiener filter gives higher (PSNR) and lower (RMSE), with a significant filter mask [3 3].
