Published: June 2021

Indonesia as archipelagic country, needs strong maritime sector security. The Indonesian Navy in Law Number 34 Year 2004 has been given the mandate to safeguard the sovereignty of the Republic of Indonesia. The Armada II Command as Kotamaops annually carries out Military Operations Other Than War (OMSP) which is carried out under the command of Guspurla and Guskamla. Intelligence information regarding the estimated threat / contingency that will occur is very influential on decision makers in operational planning. With the contingency provided by the intelligence staff, it is necessary to have an appropriate marine operation modeling. In a multi-operation operation, it is necessary to have a supporting attribute, that is, a base ship. The purpose of this study is to formulate an operation modeling using the selection of a headquarter ship which is preceded by the determination of contingency priorities. This study uses MCDM which consists of MCDA and MCDO which uses the integration of the Delphi method, AHP, Fuzzy weighting, Goal programming and linear Integer-Zero one programming. Based on the processing of Delphi and AHP, in determining the threat of OMSP, it is influenced by the number / intensity of incidents of 20.4%; impact of Ipoleksosbudhankam 29.4%, Capabiity 38.2% and involvement factor of 12.1% where national jurisdiction marine security operations are selected as the first priority. Meanwhile, in the selection of the headquarters ship which functions to coordinate the KRI in carrying out sector patrols, using the FWH and IGP, the KRI was chosen as the Sigma class to be the headquarters ship. This modeling uses 22 of the 24 KRI that have been allocated by obtaining an increase in the optimization of the coverage area and fuel savings..

Published: June 2021

An amphibious plane is an aircraft to carry out cargo delivery and an aircraft for emergencies to reach remote islands in the archipelago. A pontoon or buoy is a hull that is useful as a bearing for landings in water areas. This is done to assist aircraft landing without using an airplane runway. This research aims to create a new configuration of the distance between one pontoon and another. Numerical calculations and analysis are useful for seeing the characteristics of the floating pontoon design's resistance. An investigation of interference waves was also carried out in this study to validate the experimental data generated by the pontoon hull. Numerical calculations are carried out on the CFDSOF application to predict hull resistance with three variations to the floating pontoon's separation distance. The simulation is carried out at the Operating Empty Weight condition on the Indonesian Aerospace aircraft with the IAe N219 model. The results show that the Froude Number speed is between 0.3 to 0.8. There is a reduction in drag on the hull so which makes takeoff operations easier.

Published: June 2021

This research investigated the effects of ethanol blending with methanol-gasoline as fuels in spark ignition engine and how it affects engine performance and emissions. Four ethanol-methanol-gasoline (GEM) blends were prepared with variable ethanol concentrations (0%, 5%, 10%, 15%) and constant methanol concentration (10%) and denoted as M10, E5M10, E10M10, and E15M10 in reference to each respective alcohol constituents. Physicochemical properties testing revealed that density and kinematic viscosity of GEM fuel blends increases with ethanol concentration. E15M10 has shown the most increase in density and kinematic viscosity with 10.7% and 18.7% increase respectively. In contrast, calorific value decreased as ethanol concentration decreases. E15M10 displayed the lowest calorific value at 16.9% lower than gasoline. Meanwhile, engine performance and emissions test showed that GEM fuels generally possess increased average Brake Thermal Efficiency (BTE) than pure gasoline. However, average Brake Specific Fuel Consumption (BSFC) for pure gasoline is lower. E15M10 displayed highest increment of BSFC at 17.2% average increase. Meanwhile, E10M10 displayed the highest improvement in BTE with an average of 9.4% increase. Exhaust emissions indicate that all GEM blends produced increased carbon dioxide (CO2) and oxides of nitrogen (NOx) emissions while carbon monoxide (CO) emissions decreases. E15M10 showed the most reduction in CO emissions with 90.6% decrease while E10M10 has shown the most increased CO2 and NOx emissions with 110% and 6.7 times increase respectively. In conclusion, up to 15% volume of ethanol blending with 10% volume methanol-gasoline was able to improve engine performance and emissions in terms of BTE and CO emissions.
Investigation of Flow Pattern and Void Fraction of Air and Low Surface Tension Liquid in A 30° Inclined Small Pipe
Authors: Sudarja  , Sukamta  , Fauzan Saputra
Published: June 2021

Two-phase flow in the mini pipe is applied in wide fields. The most common of two-phase flow is a couple of gas and liquid. The essential properties of the liquid are density, viscosity, and surface tension. There are many variations of the flow direction, horizontal, incline, and vertical, in terms of orientation. The two-phase investigation of flow pattern and void fraction of air and low surface tension liquid in a 30° inclined small pipe has been carried out. Dry air was used as a gas phase, while the liquid was the mixture solution of distilled water and 3% (by volume) of butanol. Butanol addition aimed to decrease the surface tension, which became 42.9 millinewton/meter, instead of 71 mN/m when using distilled water. The test section was a 130 mm length, 1.6 mm inner diameter circular glass pipe. The rig used was equipped with the air compressor, pressure tank, high-speed camera, liquid flow meter, and gas flow meter. The liquid was fed to the test section by the pressurized tank, instead of directly pumped, to avoid pulsation. Ranges of gas and liquid superficial velocities were 0.025 – 66.3 m/s and 0.033 – 4,935 m/s, respectively. Flow patterns were obtained from the captured high-speed video. Meanwhile, the void fractions were acquired by image processing of the video. As a result, five distinctive flow patterns were observed: plug, slug-annular, churn, bubbly, and annular. The separated flow was absent. The change of the liquid surface tension affected the shifting of some transition boundary lines in the flow pattern map. The transition line between slug-annular and annular against churn flow was shifted to the lower side or toward lower JL when the liquid surface tension decreased. In short, the churn flow was easier to be formed when the liquid surface tension was lower.

L’intime dans la relation transférentielle : quels mots pour le dire ?
Authors: Druet Laurence
Published: June 2021

Je développe dans ce texte l’idée que toute personne crée de manière très personnelle et unique un récit subjectivé, une fiction intime de son vécu. Le travail en analyse consisterait donc en une rencontre avec un récit non pas linéaire, ni chronologique de l’histoire du sujet mais avec une intrigue, et ses soubassements souterrains. Aussi, je souligne l’importance du silence en séance, du temps nécessaire pour que les mots justes se posent ; du nid transférentiel indispensable, en résonance avec le nid originel, pour permettre au (à la) patient(e) une rencontre intime avec lui (elle)-même, vers une éventuelle transformation.
À l’ombre d’éros
Authors: Galdo Giovanna
Published: June 2021

Comment entendre les mots « masculin » et « féminin » et les qualités qu’on leur attribue ? Comment entendre leur radicale mise en discussion, à l’œuvre depuis quelques décennies ? Traditionnellement on associe à ces deux mots les concepts jungiens d’anima et d’animus. Toutefois deux autres concepts issus également de la théorie jungienne, à savoir l’éros et le logos, et plus précisément le très ancien et profond clivage qui a été acté entre eux, peuvent être fort utiles dans la tentative de comprendre et d’expliquer les importantes modifications que connaît aujourd’hui l’articulation du « masculin » et du « féminin » tant au niveau individuel que collectif.
Le tournant de la charité sociale au XIX e siècle : la dimension théologale au défi de l’efficacité
Authors: Fino Catherine
Published: June 2021

Cet article analyse l’évolution de la charité sociale du xix e  siècle jusqu’au concile Vatican II, en trois lieux significatifs : le soin aux malades, l’aide sociale et la philanthropie, avant de vérifier si les mêmes déplacements caractérisent la référence à la charité dans la doctrine sociale de l’Église. La technicisation et la professionnalisation du soin médical et social comme de la philanthropie révèlent la primauté accordée à l’efficacité, caractérisée par le vocabulaire de l’assistance. Le mot charité désigne désormais l’assistance non qualifiée. La doctrine sociale de l’Église réussit mieux à ressaisir la quête d’efficacité au profit d’une définition théologale de la charité. Aujourd’hui, la critique du « paradigme technocratique » et la perception de la vulnérabilité des vivants comme source de créativité désabsolutisent la quête d’efficacité au profit de l’écoute des « pauvres » et des « périphéries ».
Susciter la générosité : le langage des organismes caritatifs et humanitaires
Authors: Greiner Dominique
Published: June 2021

La montée de l’action humanitaire et le renouveau de la philanthropie ont tendance à ringardiser la charité et ses pratiques. Pourtant le monde caritatif confessionnel a beaucoup changé. Il a su faire évoluer sa communication grâce à des campagnes confiées à des agences de publicité. Cette contribution cherche à dégager ce que les organismes caritatifs confessionnels disent de la charité à travers leurs campagnes de sollicitation de dons.
L’implication des cisterciennes dans la vie religieuse urbaine
Authors: Hélias-Baron Marlène
Published: June 2021

Fondée à la fin du xii e siècle pour accueillir des prostituées repenties, Saint-Antoine-des-Champs est devenue, en 1204, une abbaye cistercienne de femmes à l’initiative de l’évêque de Paris, Eudes de Sully. Loin d’être isolée, elle a été implantée dans un espace en cours d’urbanisation sur la rive droite de la Seine, à l’extérieur de la muraille de Philippe-Auguste. Ce monastère suburbain apparaît en relation constante avec la ville et ses habitants, par sa position sur une voie de communication importante entre la capitale et Vincennes, par le recrutement de ses moniales, mais aussi par l’organisation d’un pèlerinage et par l’accueil de prédicateurs influents. Favorisé par un contexte porteur pour les établissements de cisterciennes, il a reçu de nombreux actes mettant en évidence les liens tissés avec les Parisiens, notamment à travers la documentation testamentaire. À la fin du xiii e siècle, il est complètement intégré à l’offre religieuse parisienne.
Religion civique ou affiliation communautaire ?
Authors: Bourlet Caroline , Bove Boris
Published: June 2021

Le concept de « religion civique » est le plus souvent abordé sous l’angle des pratiques religieuses collectives. Les processions paniques de 1412 permettent d’établir qu’elles tournent autour des reliques des saints royaux et des saints parisiens, mais qu’elle est moins royale au xv e siècle qu’elle ne le sera durant les guerres de religion, et aussi moins structurée autour culte de sainte Geneviève. Une approche individualisée de la question à travers un corpus de 69 testaments du xiii e - xv e siècles permet de poser la question de la réalité de l’adhésion des citadins à ces rituels collectifs. Il en ressort que les bourgeois ne cherchent pas plus leur salut auprès des saints royaux que des saints civiques. Au contraire, ils recherchent surtout les prières des pauvres de l’Hôtel-Dieu, des Quinze-Vingts et des léproseries de Paris, qui prennent en charge toutes les facettes de l’assistance à l’échelle de la ville. Cette dévotion partagée entre différentes strates de la société relève moins de la religion civique, que d’une affiliation communautaire dans le cadre d’un catholicisme corporatif à l’échelle de la ville, gage d’une très forte identité urbaine.

Authors: Huang Yusen , Dong Xiaojin , Zhang Jing , Wan Xiaomei , Wang Menghan , Xie Lixin
Published: June 2021

PURPOSE:

To evaluate the short-term outcomes of implantation of a full-diffractive multifocal intraocular lens (IOL) with optic capture for selected pediatric cataracts.

METHODS:

In this prospective study, patients with pediatric cataract aged 3 to 14 years were selected to receive multifocal IOL (Tecnis ZMB00; Abbott Medical Optics) posterior optic capture. Visual acuity, stereopsis, visual quality, and complications were assessed.

RESULTS:

Forty-five patients (66 eyes) were recruited with a follow-up of 9.09 ± 5.93 months (range: 6 to 24 months). The cataract was bilateral in 21 patients and unilateral in 24 patients. At the last follow-up visit, the mean distance-corrected distance, intermediate, and near visual acuity was 0.28 ± 0.25, 0.43 ± 0.24, and 0.39 ± 0.27 logMAR, respectively. Among the patients with bilateral cataract, postoperative corrected distance visual acuity (CDVA) was 20/40 or better in 79% (33 of 42) of the eyes and 20/20 in 26% (11 of 42) of the eyes. Of the patients with unilateral cataract, 54% (13 of 24) achieved a CDVA of 20/40 or better but none obtained a CDVA of 20/20. All patients developed stereopsis postoperatively (
P
< .05). There was no significant difference in modulation transfer function cut-off and Strehl ratio between the eyes with a multifocal IOL and the healthy eyes of patients with unilateral cataract (
P
> .05). Objective Scatter Index values were significantly better in the healthy eyes (
P
< .05). No posterior capsule opacification, posterior synechiae, secondary glaucoma, pigmentary IOL deposits, or IOL decentration was observed during the follow-up period.

CONCLUSIONS:

Short-term follow-up results suggest full-diffractive multifocal IOL optic capture may benefit appropriately selected patients with pediatric cataract.

Comparison of Imaging Characteristics on Computed Tomography and Magnetic Resonance Urography in Urological Conditions
Authors: Verma Nitya , Rastogi Rajul , Pratap Vijai , Pushkarna Arawat
Published: June 2021

Introduction:

Urinary tract (UT) pathologies are common causes of morbidity presenting mainly as acute flank pain, obstructive uropathy, and hematuria with calculus being the commonest cause. Computed tomography (CT) (noncontrast, contrast enhanced and urography) of the kidney, ureter, and bladder region has been considered as the mainstay in evaluation of patients with UT symptoms. Limitations of radiation exposure and risks of contrast injection in CT have provided space for magnetic resonance urography (MRU) that has recently gain acceptance. However, MRU is limited by its availability and higher cost. Thus, with the aim of evaluating the scope of MRU in various UT pathologies, we planned a comparative study between CT scan and MRU.

Materials and Methods:

Thirty-five patients with UT symptoms (acute flank pain, obstructive uropathy, and hematuria) were evaluated with CT scan and MRU after obtaining approval from Institutional Ethics Committee and written informed consent from the participants of the study. CT scan was performed on 128-slice CT scanner while MRU was performed on 1.5T magnetic resonance scanner using the standard protocol. The data thus recorded in a single-blinded manner were analyzed using appropriate statistical methods and tools.

Results:

Compared with CT scan, MRU had a poor accuracy in detecting UT stones especially <6 mm and without secondary signs of obstruction. However, MRU performed very well in patients with obstructive uropathy and hematuria subgroup with no significant difference in accuracy from CT scan. Overall, MRU had a moderate sensitivity of 76.3%, high specificity of 96.9% and moderately high accuracy of 85.7%.

Conclusions:

Although MRU has lower sensitivity to small sized UT calculus but is very specific to secondary signs of obstruction as well as to causes of obstructive uropathy and hematuria. It can serve as an excellent alternative tool especially in patients with contraindication of contrast injection in CT scan as well as in children, during pregnancy and in conditions requiring repetitive examinations.

Published: June 2021

Introduction:

Celiac disease (CD) is a chronic gastrointestinal disorder arising due to gluten sensitivity in susceptible individuals. In India, one person per 100 is suffering from this disease. CD has been reported more in high wheat-consuming areas like northern India. However, the incidence of CD in patients attending tertiary care hospital of Uttarakhand has not yet been reported. Therefore, this study was planned.

Materials and Methods:

A retrospective study with 603 patients was done at AIIMS Rishikesh in Biochemistry Department. These patients were screened for CD by tissue transglutaminase antibodies (ttgA) levels using enzyme-linked immunosorbent assay method. Percentage of levels of ttgA <4 U/ml (normal value) and >4U/ml in male, female adults, and children was calculated. Chi-square test was applied to compare results.

Results:

Out of 603 patients, 23 (3.81%) had abnormally raised ttgA levels (>4 U/ml). Percentage (15.18%) of ttgA levels in male children was significantly (P = 0.01) higher than 2.56% in female children. Mean + standard deviation (SD) of normal and abnormal ttgA levels in patients was 1.17 + 0.45 versus 66.81 + 34.80 U/ml, respectively. Mean + SD of abnormal ttgA levels in children and adults was 72.84 + 41.91 versus 32.38 + 24.75 U/ml, respectively. There was a statistically significant difference in abnormal ttgA levels among children and adults with children predominantly being higher (P = 0.0235).

Conclusion:

This study shows that levels of ttgA suggestive of CD in children are higher as compared to adults and more in males than females attending tertiary care hospital of Uttarakhand.

Authors: Khare Vaibhav , Rastogi Rajul , Mishra Amit , Neha  , Singh Abhishek Kumar , Kumar Sunil , Singh V. K. , Pratap Vijai , Yeshlawat Nitishkumar
Published: June 2021

Introduction:

Colorectal disease, especially carcinoma, is an important cause of morbidity and mortality in modern era. With rising incidence of colorectal diseases and due to limitations of conventional flexible fiber-optic colonoscopy (gold standard tool), imaging plays a significant role in evaluation of these patients. Recent technical advancements coupled with noninvasive and radiation-free nature has made magnetic resonance imaging (MRI) an acceptable screening tool in colorectal diseases. Hence, we planned this study to evaluate role of MRI in colorectal diseases in our tertiary care, medical college, hospital.

Materials and Methods:

Forty-four patients with signs and symptoms of colorectal disease were evaluated by 1.5 Testa MRI followed by conventional, flexible, fiber-optic colonoscopy on the same day after obtaining approval from the institutional ethics committee and after obtaining written informed consent using strict criteria. Bowel preparation was done using polyethylene glycol. Data from MRI and colonoscopy were recorded in predesigned pro forma and compared with the final diagnosis. Appropriate statistical methods and tools were used to evaluate the results.

Results:

Majority of the patients in the study were in the age group of 21–40 years with male predominance. Altered bowel habit followed by bleeding per rectum was the most common presentations. Both MRI and colonoscopy overdiagnosed the lesions as malignant with higher errors by MRI. MRI was very effective in the detection of growth, strictures, diverticulosis, mucosal thickening/edema, and extracolonic manifestation but failed in detecting small polyps and ulcers. MRI had high sensitivity and negative predictive value (NPV) of 100% with an accuracy of more than 70%.

Conclusions:

Although conventional colonoscopy is considered as a gold standard tool in the diagnosis of colorectal diseases, it has several limitations including its invasive nature and low yield as a screening tool. Hence, MRI with its noninvasive and radiation-free nature along with its high sensitivity and NPV for malignant lesions should be considered over colonoscopy as well as computed tomography in evaluation of colorectal diseases.

Published: June 2021

Introduction:

One of the factors determining the quality of health service delivery is well-trained and qualified health personnel. In addition to receiving a quality education to train qualified health personnel, the importance of the learner being ready and motivated to learn is obvious. The purpose of this study is to examine the relationship between motivational persistence and achievement goal orientations of Vocational School of Health Services students.

Materials and Methods:

In this research, which is structured in relational comparison type besides its descriptive feature, we studied with 278 students studying at Health Services Vocational School. The data were obtained with "Motivational Persistency" and "Achievement Goal Orientation" scales. In the analysis of the data, correlation and path analysis were used as well as descriptive statistics.

Results:

When achievement goal orientation and motivational persistency are examined with all subdimensions, the motivation to follow long-term goals was positively significant with the learning approach. The motivation to follow the current goals was positively significant with the motivation to learning approach achievement and to follow long-term goals while was negative with motivation to approach the performance. The motivation to repeat unattainable goals has been found to be positively significant with the motivation to learn approach, learn avoidance achievement orientations and long-term goals, and to follow existing goals.

Conclusion:

The results of the research showed that students' achievement learning approach and motivational persistency were prone to iteration subdimensions of unattainable goals. Although the study parallels with the literature, it is important to provide a better understanding of how the achievement goal orientation of the students of the Vocational School of Health Services affects the processes of motivational persistency.
Utility of Fine-Needle Aspiration Cytology in Diagnosis of Cutaneous and Subcutaneous Metastasis
Authors: Nair Nidhi , Chikkannaiah Panduranga , Venkataramanappa Srinivasamurthy , Shivanna Ragunatha
Published: June 2021

Introduction:

Cutaneous metastasis (CM) is an uncommon clinical presentation and poses trouble in diagnosis. However, it is remarkable and can occur due to a known or an unknown primary tumor. Despite the fact that clinical assessment helps in the diagnosis, Fine-needle aspiration cytology (FNAC) is a modest, basic, and quick principle line of investigation for the finding of CM.

Materials and Methods:

It was a retrospective study conducted in the department of pathology at a tertiary care teaching hospital. The study was conducted from January 2010 to May 2020. All cases of CM that has been diagnosed by FNAC were included.

Results:

During the study period, a total of 37 cases of CM were observed, constituting 0.15% of all FNACs. The age of the patients ranged from 35 to 74 years, and the male: female ratio was 1.05:1. Primary tumor was known in all 37 cases. Among males, lung carcinoma was the more common whereas breast was the most common organ of primary among females. The most common lesion was a single nodule (27 cases), with predominant site being chest wall (32.5%), and the most common tumor at microscopy was metastatic adenocarcinoma.

Conclusion:

FNAC is a fast and safe procedure that can be utilized as a first line of investigation in diagnosing metastatic skin lesions. Basic assessment of cytomorphology alongside significant clinical subtleties could help in recognizing the site of an unknown primary.
The Correlation of E-cadherin Expression with the Modified Gleason Score and the Grade Group of Prostatic Adenocarcinoma
Authors: Hayder Sakar Azad , Raziq Alaa Hani
Published: June 2021

Background:

E-cadherin is a cell adhesion molecule, its downregulation is associated with poorly differentiated tumors in many organs, and its loss is associated with adverse behavior of many tumors.

Objectives:

This study aims to find a correlation between E-cadherin status, the Grade Group, and the modified Gleason score in core biopsies obtained from prostatic carcinoma.

Materials and Methods:

This study is a retrospective and prospective cross-sectional study that was conducted on (50) paraffin blocks obtained from core biopsies of prostatic carcinoma. E-cadherin status was correlated with the Grade Group and the modified Gleason score. The E-cadherin staining pattern was also examined for its correlation with perineural invasion. Chi-square was used to determine the correlation between E-cadherin staining pattern on the one hand and the modified Gleason score, Grade Group, and perineural invasion on the other hand and P < 0.5% was considered as significant.

Results:

Only six patients (12%) fall in Grade Group 1 and according to the modified Gleason score, most patients had high scores. Regarding E-cadherin expression, 24 cases (48%) had aberrant E-cadherin expression, while the rest 26 cases (52%) had a complete strong membranous expression. Statistically, there was a significant correlation between aberrant E-cadherin expression and increasing grade according to the modified Gleason score and Grade Group with P values of 0.032% and 0.022%, respectively. In 24 patients (48%), perineural invasion was detected half of them had aberrant E-cadherin expression which was statistically notsignificant when both the parameters (perineural invasion and aberrant E-cadherin expression) are tested against the modified Gleason score and the Grade Group (P = 0.71%).

Conclusion:

Aberrant E-cadherin expression is associated with increasing modified Gleason score and Grade Group but has no significant correlation with perineural invasion.

Authors: Ali Nidhal Abulkader Mohammed
Published: June 2021

Background:

Hyperalgesia and allodynia are abnormal sensory signs which are usually seen along neuropathic pain (NP) in patients on paclitaxel (PT) chemotherapy. Pomegranate seed oil (PSO) has been used in the traditional medicine for the different kinds of pain. Nucleo-CMP Forte® (NCF) is a nucleotide-based drug and L-carnitine (LC) is a member of natural compounds have been shown effective in diverse peripheral neuroglial disorders. The aim of this study is to compare the anti-hyperalgesia and anti-allodynia activity of PSO, NCF, and LC in PT-induced neuropathy.

Materials and Methods:

Thirty adult male mice were divided equally into five groups of six mice in each group as follows: Control (C), PT, PSO (PTpso), NCF (PTn), and LC (PTc) groups. NP was induced by the administration of PT (6 mg/kg, i. p., once weekly) to the mice in all groups except C group. PSO, NCF, and LC were administered orally once daily to mice with PT-induced neuropathy in their corresponding groups. Different behavior parameters were used to test the anti-hyperalgesic and anti-allodynic effect of PSO, NCF, and LC on days 0, 7, 14, 21, and 28 of PT administration.

Results:

PSO, NCF, and LC significantly attenuated NP induced by PT from day 14 up to 28 days using the different behavioral tests for thermal hyperalgesia and allodynia.

Conclusion:

PSO, NCF, and LC have significant potential anti-nociceptive and analgesic activity against PT-induced NP and PSO was the most efficacious than NCF and LC.

Authors: Amen Shwan Othman , Rasool Banan Qasim
Published: June 2021

Background:

Coronavirus disease-2019 (COVID-19) pandemic has led to a radical transformation of economic, social, and health-care networks. COVID-19 pandemic has reported a substantial drop in the number of patients presenting to cardiology Emergency Departments with acute coronary syndromes/acute myocardial infarction (ACS/AMI) and a drop in number of cardiac procedures.

Objective:

The objective was to describe how lockdown and COVID-19 pandemic has affected the evolution of AMI and hospital admissions due to ACS. We aimed to assess the impacts of COVID-19 on cardiology services and procedures performed on a daily basis before and during the pandemic.

Materials and Methods:

This single-centered retrospective study included all the consecutive patients with ACS/AMI including ST-segment elevation myocardial infarction (STEMI) and non-STEMI admitted to ER of Surgical Specialty Hospital-Cardiac Center/Erbil-Iraq, from the start of the lockdown (March 15, to April 15, 2020). The same analysis was conducted among patients presenting with ACS/AMI at the same identical time period before Lockdown (March 15, to April 15, 2019).

Results:

A total number of 40 patients admitted at SSH/Cardiac Center-Erbil with ACS/AMI during the study period, and showed a 37.5% drop in the number of patients with Myocardial Infarction comparing with the corresponding time window before the COVID-19 pandemic.

Conclusion:

Platelet-Rich Plasma in Oral and Dental Surgery
Authors: Al-Noaman Ahmed Salah
Published: June 2021

Background:

Platelet-rich plasma (PRP) has been employed widely in dental and oral surgery. However, there is considerable debate about its effect on wound healing and inflammatory response.

Materials and Methods:

PubMed, Google Scholar, Scopus data base, and manual search were performed to find out articles on the use of PRP in dental and oral surgery using keywords such as PRP , oral surgery, dental surgery, lower wisdom teeth, periodontal pocket, dental implant, tooth socket preservation, dry socket, cystic lesion, and ridge augmentation. These articles discussed the use of PRP (after surgical removal of wisdom teeth, treatment of periodontal pocket, ridge preservation, implant stability, prevention of dry socket, treatment of bony defect after cystic removal, and ridge augmentation).

Results:

Twenty-seven articles were found on the usage of PRP in dental and oral surgery. Six articles on the use of PRP after surgical removal of lower wisdom teeth, five articles in the treatment of periodontal pocket and implant stability, four article in ridge preservation, three articles in prevention of dry socket and two articles on the use of PRP after cystic removal and ridge augomentation.

Conclusion:

PRP enhanced bone regeneration and soft-tissue healing aftery lower wisdom tooth surgery. It decreased the depth of periodontal pocket, maintained implant stability, preserved ridge height and prevented dry socket. However, PRP had no effect on pain, swelling, and bleeding. There is no justification for the impact of PRP on bone augmentation and healing of bony defect after cystic removal of the jaws. More studies should be carried out to support the usage of PRP in oral and dental surgery.

Authors: Karahda Aarti , Prasad Shobhit Kumar , Singh Priti , Gupta Rajiv
Published: June 2021

Background and Objectives:

Injection drug usage is a major public health issue. The study is aimed to find the clinical profile and trends of injection drug usage in young people who attended de-addiction services at a tertiary care center in North India.

Methods:

This retrospective record review analyzed data from consecutive young-aged people attending de-addiction services at a tertiary care hospital in North India between 2015 and 2019. The sociodemographic data and clinical and injection-related characteristics were discerned from the data.

Results:

Out of 135 patients included in the analysis, 132 (97.8%) were male. There was a 13-fold rise in treatment seeking over the past 5 years (2015: 7 vs. 2019: 98). One hundred and thirty-two (97.8%) were male. High Risk behavior was present such as sharing of needles in 31 (22.9%), paraphernalia sharing in 24 (17.8%), 6 (4.4%) reported ever-having symptoms of sexually transmitted infection, 13 (9.6%) had sex with sex worker, 9 (6.7%) reported ever-having HIV screening, 6 (4.4%) reported having HIV positive status. Thirty-two (23.7%) reported having previous treatment for drug abuse and 13 (9.6%) reported previously being hospitalized for drug abuse. Heroin usage has been present in 96 (71.1%) followed by pentazocine usage in 19 (14.1%).

Conclusion:

Our findings revealed that treatment-seeking young age population (the WHO defined age group 15–24 years) from the defined geographical location has been showing an increasing trend in injecting drug user usage along with greater injection and sexual risk behaviors associated with it. This can be used to design the public health strategy to educate regarding avoiding injection drug-related practices.
Pediatric Epilepsy Care in Nigeria
Authors: Igwe Wilson Chukwuneke , Aronu Ann Ebele
Published: June 2021

Epilepsy is a neurologic disorder of the brain characterized by an enduring predisposition to recurrent unprovoked seizures. It is the most common childhood neurologic disorder world-wide. Poor management often impacts negatively on the child's neurodevelopmental, emotional, physical, and social well-being. In resource-poor countries, the majority of children with epilepsy are managed by primary care physicians who are not sufficiently trained to offer effective care in pediatric epilepsy. Many low income countries do not have nationally approved guideline on management of pediatric epilepsy. Access to specialist care is costly and may involve long distance travels from rural areas to the cities. This often leads to a huge treatment gap. Efforts aimed at increasing the management skills of primary-care physicians in diagnosing and giving appropriate treatment is necessary in ensuring reduction in treatment gap. This review article is based on the authors' clinical experience and a review of 20 published works from review articles, recommendations, and guidelines sourced from PubMed and Google using the search terms “Paediatric epilepsy, management, primary care.” In the absence of any approved national guideline, a simplified approach to the clinical diagnosis, appropriate use of available diagnostic facilities, and cheap but cost-effective drugs will lead to better management of childhood epilepsy in resource-constrained settings.

Published: June 2021

Introduction:

Asymptomatic bacteriuria (ASB) in pregnancy is defined as the presence of at least 105 colony-forming units per milliliter of a bacteria species in clean-catch urine in the absence of obvious symptoms of urinary tract infection during pregnancy. It is associated with obstetric complications such as preeclampsia, pyelonephritis, preterm labor, low birth weight, and prematurity. Determining the microbial isolates and sensitivity patterns of ASB among pregnant women locally will aid the management of ASB in pregnancy and prevention of complications associated with it.

Objective:

The aim of the study was to determine the microbial isolates and sensitivity pattern among antenatal patients with ASB at the Federal Medical Center (FMC), Keffi, Nasarawa state.

Materials and Methods:

This is a cross-sectional study among pregnant women attending the antenatal clinic at the FMC, Keffi, with ASB. Clients who met the selection criteria were recruited for the study. A structured pro forma was administered, and midstream urine samples were collected and processed. Result was analyzed using the Statistical Package for the Social Sciences version 20. Chi-square at a significant level of 0.05 and confidence level of 95% was used to determine significance.

Results:

A total of 184 consented women presenting for their first antenatal visit were screened for ASB, of which 82 were positive for significant bacteriuria, giving a prevalence of 44.6%. The ages of the participants ranged from 18 to 43 with a mean age of 29.58 ± 5.42 years. The common uropathogens isolated were Staphylococcus aureus 43 (52.4%), Klebsiella spp. 14 (17.1%), and Escherichia coli 13 (15.9%). The isolates were most sensitive to amoxicillin-clavulanate (85.4%), nitrofurantoin (82.9%), and gentamicin (79.3).

Conclusion:

The prevalence of ASB among the study participants was high. S. aureus, Klebsiella spp., and E. coli were the predominant organisms cultured while most of the isolates were sensitive to amoxicillin-clavulanate, nitrofurantoin, and gentamicin.

Published: June 2021

Bryophyllum pinnatum is an important enthnomedicinal plant. The study assessed the effect of crude aqueous leaves extract of Bryophyllum pinnatum (CALEBP) on fasting plasma glucose (FPG), antioxidant status, lipid profile, liver and renal function indices in albino rats. The rats were housed under standard laboratory conditions (12h light: 12h dark photoperiod), 23± 2 ºC and were given rat pellets and tap water ad libitum. Twenty four rats weighing 190-232g were randomized into four groups (A-D) of six rats each. Group A (control) received normal feed and water only. Groups B, C and D received orally 180, 360 and 540 mg/kg body weight respectively of CALEBP for 28 days. Serum aminotransferases, alkaline phosphatase (ALP), superoxide dismutase, catalase, FPG, lipid profile, urea, creatinine, bilirubin, proteins, malondialdehyde, glutathione (GSH) and total antioxidant capacity (TAC) and electrolytes were assessed by standard methods. Data were analyzed using one-way analysis of variance and p<0.05 was considered statistically significant. Groups C and D had significantly lower FPG (p = 0.030; p = 0.01) and higher ALP (p = 0.01; p = 0.001) compared to the controls. Group D had significantly lower creatinine (p = 0.03) and K+ (p = 0.02) compared to control. Group B, C and D had significantly lower GSH (p = 0.020, p = 0.000 and p = 0.000) while group B had significantly higher TAC (p = 0.04) compared to the controls. Dosage of extracts correlated positively with ALP (r = 0.705, p = 0.000) and negatively with FPG (r = -0.603, p = 0.002), K+ (r = -0.563, p = 0.004), creatinine (r = -0.464, p = 0.022) and GSH (r = -0.786, p = 0.000). Bryophyllum pinnatum aqueous leaves extract could lower blood glucose, potassium and creatinine  levels and may increase ALP activity and GSH depletion in high doses.

Published: June 2021

The present study was undertaken to investigate the duration of exposure dependent effect of carbamate treated net on haematological indices in Wistar rats. Eighteen (18) Wistar rats were used in this study and designated into three (3) study groups of six rats each. Group 1 was the control group while groups 2 and 3 constituted the experimental groups containing rats exposed to carbamate treated net for 30 and 60 days respectively. At the end of the exposure period, the animals were sacrificed and blood sample were removed for haematological analysis. The result of the study shows that there was a significant increase in the body weight of exposed rats compared to rats in the control group at (P<0.05). Relative organ weight of the exposed rats increased significantly (p<0.05) when compared to rats in the control group. The PCV, Hb, RBC’s, PLT, MCV, MCH, and MCHC levels all increased insignificantly in the exposed rats when compared to rats in the control group at (p<0.05). The study also revealed that the total White Blood Cell (WBC) counts in the exposed groups was significantly elevated when compared to the control group at (P<0.05). Finally, the result of the study shows a significant increase (p<0.05) in the levels of neutrophil of the exposed rats when compared with the control group, while the level of lymphocytes, eosinophils and monocytes increased insignificantly (p>0.05) in rats exposed for 30 days but increased significantly (p<0.05) in rats exposed for 60 days when compared to rats in their control group. Therefore, the observation from this study suggests that long-term exposure to carbamate treated net may alter the haematological indices and hence lead to various health problem.
