Authors: Choudhury Chayanika , Bora Utpal
Published: June 2021

Introduction: Phenomenology is the study of subjective experience. Psychiatric diagnoses are based on cross-sectional psychopathological features, for example, the presence of rst-rank symptoms in the case of schizophrenia. Phenomenological investigation focuses on the form of experience, i.e. the way in which the content is experienced, while the content itself is of secondary importance. This study was conducted to investigate the subtle differences between early-onset group (onset before 18 years of age) and late onset (onset after age of 40 years). Aim And Objectives: To study the socio-demographic prole and phenomenology of early onset psychosis and late onset psychosis compare them based on the variables studied. It is a cross sectional observational Materials And Methods: study carried out in the Department of Psychiatry, Gauhati Medical College and Hospital during the period of June 2018- May 2019. A semi structured, self designed proforma has been used to collect the socio-demographic data and personal details of the patients and their treatment history. The ICD-10 Classication of Mental and Behavioural Disorders, WHO, 1992, Brief Psychiatric Rating Scale (BPRS) Version 4.0, Modied Kuppuswamy Socio-economic status scale were used along with. All the data that was derived from the study were analyzed by using the software IBM SPSS 21.0. Observations And Results: Mean age of presentation in early onset psychosis is 19.22 years with Standard Deviation ±5.69. Mean age of presentation in early onset psychosis is 54.5 years with Standard Deviation ±11.9. Signicantly higher ratio of male was noted in early onset group and higher ratio of female was noted in that of the late onset group. Somatic concern, anxiety, depression and suspiciousness was signicantly more in late onset psychosis. In comparison to the group of late onset psychosis, self-neglect, blunted affect, emotional withdrawn, motor retardation, motor hyperactivity, mannerisms and posturing were signicantly more in early-onset psychosis. Major distinction was noted in the Conclusion: distribution of delusional disorders and acute and transient psychotic disorders. Age of onset was skewed to late adolescence with more number of male patients. Late onset psychosis group had more uneducated patients with considerable proportion of adults left unmarried in the late onset group. Late onset psychosis group shows predominance of somatic concern, anxiety, depression and suspiciousness in contrast to early onset psychosis group which shows predominance of motor hyperactivity, self-neglect, blunted affect, motor retardation, mannerisms and posturing

Authors: Sood Neelam , Chopra Shikha
Published: June 2021

INTRODUCTION: Hodgkin's lymphoma (HL) is a lymphoproliferative neoplasm constituting less than 1% of all
neoplasms. It has been categorized into- nodular lymphocyte predominant HL and classical type with subtypeslymphocyte rich, lymphocyte depleted, nodular sclerosis and mixed cellularity. Nodular sclerosis Hodgkin's lymphoma (NSHL) is difcult to
diagnose on FNA because of the lack of Reed Sternberg (RS) cells, low cellularity and difculty in identifying the counterpart of lacunar cells.
CASE A 16-year-old female presented with anterior chest wall swelling si REPORT: nce 6 months measuring 5x4cm along with incidentally
noted cervical lymph nodes measuring 2x2cm and 1x1cm. On examination, multiple papular skin lesions were observed. FNAC smears from
cervical lymph node showed high cellularity, with sheets of binucleated and multinucleated cells having multiple nucleoli, some showing pale
bluish abundant cytoplasm whereas others showing dense cytoplasm; in a background of reactive lymphoid population with few neutrophils.
Few giant cells showed hyperchromatic nuclei. Abnormal mitosis seen. No typical RS cell was seen. Peripheral blood smear showed neutrophilic
leukocytosis with no atypical cell. Possibility of NSHL was considered and biopsy advised to rule out ALCL. Histological sections showed near
total effacement of lymph node architecture by nodules separated by broad brotic bands. These nodules exhibit proliferating lymphocytes with
clustered lacunar cells along with some mononucleate, binucleate and multinucleated cells. Prominent mitotic activity, angiogenesis, focal
micro abscesses were noted. Immunohistochemistry showed CD 15+ and CD 30+ expression in the giant cells, conrming diagnosis of NSHL
grade 2. NSHL poses a cytological diagnostic dilemma specially in abse CONCLUSION: nce of sclerosis on FNA, making histological
examination and IHC mandatory

Authors: asasmy Indira Ananthapadmanab , G. K. Shambhavi . , Srinivasa Rao C.H.
Published: June 2021

Background: Ocular infections are one of the major causes of visual impairment around the world. Infections can either
be due to single microbe or polymicrobial. it is essential to know the specic etiology of the infection for the effective
management of ocular infections. This study aims to identify microbes responsible for common ocular infections and to determine its antibiotic
susceptibility to commonly used antibiotics used in clinical practice.
Clinical Methods: A hospital based cross sectional study included 290 patients attending the ophthalmology department of a tertiary care
hospital. After a thorough clinical examination samples were taken and were subjected to Grams' stain, culture methods, biochemical tests for the
identication of the microbe. Antibacterial susceptibility test was performed using Kirby Bauer disc diffusion method.
Results: Among 290 patients, the common clinical conditions include conjunctivitis 108 (37.24%), keratitis 37 (12.76%), dacryocytitis 53
(18.28%), blepharitis 52 (17.93%), trauma 24 (8.28%), infective uveitis 10(3.45%) and endophthalmitis 6(2.07%). Among the total ocular
infections 146(50.34%) were positive for culture. Among the total isolated, 110(75.34%) were Gram positive and 36(24. 66%) were Gram
negative. The Gram positive bacteria isolated showed highest sensitivity to ciprooxacin (86.36%) followed by gentamycin (82.72%) and
clindamycin (80%). The Gram negative bacteria showed high resistance to tetracycline 7(19.44%), followed by amoxicillin-clavulanic acid
(30.56%).
Conclusion: The most common ocular infection is conjunctivitis followed by dacryocystitis which is most commonly caused by
Staphylococcus aureus, which showed high resistance to Amoxcillin, Tetracycline and Erythromycin. To prevent the emergence of antimicrobial
resistance, it is necessary to perform antimicrobial susceptibility testing before initiating antibiotics in clinical practice.

UNDERSTANDING PRIVATE SAVINGS BEHAVIOUR IN NIGERIA: AN EMPIRICAL ANALYSIS
Authors: Chete Louis N.
Published: June 2021

The objective of this paper is to investigate the determinants of private savings in Nigeria. The core private savings model was estimated as well as its eclectic variants to provide insights into the behaviour of private savings in Nigeria. The results are quite illuminating. While some of the variables had their hypothesized signs, others were counter-intuitive. For instance, while our results repudiated the efficacy of financial liberalization as a tool for the mobilization of private savings, it substantiates the adverse effects of an external debt overhang and terms of trade deterioration on private savings. Finally, the paper recommends an enhancement in per-capita incomes and a stable macro economy to facilitate savings and cautions on the dangers of adopting foreign models uncritically.
CATCHMENT AREAS AND UNIVERSITY GOVERNANCE IN NIGERIA: IMPLICATIONS FOR DEVELOPMENT
Authors: Bello-Imam I.B. , Nyemutu Roberts F.O.
Published: June 2021

Nigerian universities and other tertiary institutions are expected to play a pivotal role in the development of education in the country, and ultimately in national development. Recently the universities have been beset by a plethora of problems, one of which is the apparently simple but pernicious question of whether staff and students should be recruited on the basis of hiring quotas or by merit. Attempts to resolve the question has had dire implications for university governance and for the mission of the universities in national development. This is readily evident in the deployment of the concept of ‘catchment areas’, which pits ideas of equity in the plural society against those of efficiency and effectiveness. This study explores the problems associated with the emphasis on ‘catchment areas’ in the management of recruitment into Nigerian universities. The analysis points to the significant influence of factors external to the university system over its internal dynamics, with significant consequences for educational and national development.
A novel design framework of synthetic radial aperture focusing for volumetric transrectal ultrasound imaging
Authors: Song Hyunwoo , Kang Jeeun , Boctor Emad M.
Published: June 2021

In this paper, we present a novel design framework of synthetic radial aperture focusing for 3-dimensional (3-D) transrectal ultrasound imaging (TRUS-rSAF), in which multiple transmittance/reception events at different scanning angles are synthesized to reconstruct a radial plane in the target volume, securing high spatial resolution and texture uniformity. A theory-based design approach has not been available to push the envelope of the 3-D rSAF technique. Herein, a closed-form analytical description of the TRUS-rSAF method is presented for the first time, effectively delineating spatial resolution and grating lobe positions in the radial dimension of a TRUS transducer. We demonstrate a solid optimization workflow based on the theoretical foundation to improve its spatiotemporal resolution, grating lobe artifacts, and signal-to-noise ratio (SNR). A specific design criterion was considered to outperform a clinical 3-D TRUS imaging (TRUS-REF), where each radial plane is reconstructed with a single transmittance/reception event using a motorized actuator. The optimized TRUS-rSAF method significantly enhanced spatial resolution up to 50 % over the TRUS-REF method while providing clinically-effective temporal resolution (2-8 volumes per second) with negligible grating lobe artifacts. The results indicate that the proposed design approach would enable a novel TRUS imaging solution in clinics.

The article highlights the relevance of udder hygiene, sources of milk contamination with microflora, udder treatment requirements, sanitary condition control of the teats skin of cow udders, as well as a list of udder treatment products authorized in Ukraine.

Proper preparation of udder teats for milking, namely: treatment with special detergents and disinfectants, compliance with the correct milking procedure significantly reduce the risk of cows with mastitis and increase milk yield. The content of microorganisms in milk shows the hygiene of milking cows, animal health, and the presence of pathogenic and technologically dangerous microorganisms.

Bacterial contamination of milk is significantly increased due to udder diseases in cows. This increases the bacterial contamination of milk with pathogenic microbes, and the milk becomes unfit for consumption and processing (milk from cows with mastitis must be disposed of) milking procedure significantly reduce the risk of mastitis in cows and increase milk yield.

It is necessary to prevent the penetration of microbes into the teat duct for prophylactic mastitis measures Special products should be used to treat the udder after milking. These products have certain requirements, the main of which are: the ability to quickly destroy bacteria; to keep the skin of the teats in good condition; to protect the teat between milking; easy to wash off before milking to eliminate the risk of getting into the milk.

Authors: Ostapiv R. D. , Tkachenko V. І. , Bereziuk М. І.
Published: June 2021

The aim of the work was to develop and validate a method for the simultaneous identification and quantification of dihydrostreptomycin and benzylpenicillin in injectable suspensions. The method was validated by testing two preparations in the form of injectable suspensions containing benzylpenicillin 108–144 mg/ml and dihydrostreptomycin 180–220 mg/ml. Test samples were dissolved in purified water P, and standard samples: benzylpenicillin - in methanol (up to a concentration of 126 μg/ml), dihydrostreptomycin - in purified water P (up to a concentration of 200 μg/ml). The maximum allowable total uncertainty of the analysis was 1.64%, which is within the recommendations of SFU 2.0. The samples were separated on a Dionex Ultimate 3000 chromatograph equipped with a Luna C18 (2) 250 × 4.6 mm, 5 μm chromatographic column. The mobile phase was a mixture of acetonitrile and a solution of 0.01 M sodium heptanesulfonate with 0.05 M sodium phosphate trisubstituted, acidified with 0.1 M phosphoric acid to pH 6.0, in a volume ratio of 2: 8.

Under mentioned conditions, dihydrostreptomycin and benzylpenicillin were completely separated. The established parameters of the chromatographic system did not exceed the limits specified in the FDA recommendations. The calibration curves were linear in the recommended SFU 2.0 range (80–120% of the nominal concentration of the corresponding active substance). The ratio of the amount of standard sample added to the test samples with its subsequent detection in the preparation was 99.35–100.79% for benzylpenicillin and 99.49–100.12% for dihydrostreptomycin, which does not exceed the limits recommended in SFU 2.0. The precision criterion was 0.07 for dihydrostreptomycin and -0.08 for benzylpenicillin, which is within the limits recommended in SFU 2.0. At the same time, the results of the study by different analysts at different times differed by 1.3% for dihydrostreptomycin and 0.98% for benzylpenicillin, which is well within the limits adopted in the recommendations of the FDA and SFU 2.0.

Therefore, the method developed and validated by us for the simultaneous determination of dihydrostreptomycin sulfate and benzylpenicillin procaine in injectable suspensions can be considered suitable for routine analysis.

The article presents the results of studies on the effects of citric acid on the female’s body. The studies were performed on white laboratory rats of the Wistar line, which at the age of 3 - 3.5 months with a body weight of 192 - 210 g were divided into two groups of 4 individuals in each. The animals of the experimental group were fed by citric acid at a concentration of 80 mg/l of drinking water during the period physiological and puberty, fertilization and pregnancy. A control group of female rats was fed by water. The animals had free access to drinkers and food. Indicators of embryogenesis, leukocyte profile of blood and body weight of animals, weighting factor, histological changes of the liver were determined.

Female rats were found to have no abortions or premature births, however, the number of corpora lutea of pregnancy decreased by 19.2%, although there was no significant difference in control. The number of implantation sites per female was significantly lower by 28.8%. The mortality rate of embryos was 15.8%, which is 3.8 times higher than in intact animals. Regarding white blood cells, the analysis of the results indicates a tendency to increase the percentage of eosinophils in 2 times in the relation to the animals in the control group on the background of a probable increase in leukocytes by 42.4%.

The applied dose of citric acid caused certain changes in the macro- and microstructure of the liver. It is macroscopically established that under the influence of citric acid the organ is slightly enlarged, sluggish consistency and changed its color from light red to light brown. The relative weighting factors of the liver are probably higher in the relation to the control (52.12 ± 8.16 g/kg vs 43.38 ± 1.96 g/ kg).

The results of morphological studies indicate a partial violation of the lamellar structure of the organ in the centro-lobular region, which is due to turbid swelling of the cytoplasm of hepatocytes. In most cells, the contours are blurred, the cytoplasm is poorly stained, their nuclei are weakly basophilic, and hepatocytes with a lysed nucleus in a necrobiosis condition also occur. However, among dystrophic altered cells are clearly isolated hepatocytes with a uniformly colored basophilic cytoplasm, nucleus, rich in chromatin, which indicated the activation of reparative processes. Kupffer cells in this area are mostly round, located in the lumen of the sinusoid. Therefore, occurs a violation of lipoprotein complexes of cells and increase the permeability of cell membranes, which is reflected in the development of protein dystrophy with varying degrees of severity. Activation of reparative processes of hepatocytes is also determined.

Published: June 2021

The long moratorium on state control (supervision) over the activities of business entities has led to an increase in the volume of unregistered, low-quality, counterfeit and counterfeit veterinary products on the Ukrainian market. Violations by manufacturers regarding the entry into circulation of dangerous products are also due to the long absence of licensing of production and sale of products for veterinary medicine and animal husbandry. In these circumstances, there are numerous complaints from consumers about the low quality and safety of veterinary drugs, feeds, feed additives and premixes. The article covers the issues of examination of product appearance, labeling, primary (group) and secondary (transport) packaging, which is carried out in order to establish the conformity of manufactured products to the requirements declared in the regulatory documentation, which will identify dangerous products on the domestic market. In carrying out the examination of veterinary goods presented by consumers and other enterprises or institutions, the general procedure for its conduct shall be established. They check the completeness of the sent materials and check their availability with the corresponding list in the cover letter, open the sealed samples by commission and find out whether the veterinary drug has been registered in Ukraine. Then the data presented in the materials are compared with the registration materials and normative documentation, and a protocol of product inspection for compliance with the requirements declared in the dossier, registration certificates, technical conditions, quality certificates, etc. is drawn up. Examination of the appearance of the label is carried out visually, comparing with the original or with the materials of the relevant registration dossier. Check the correct labeling and packaging of products, and it is important to pay attention to the statement of the summary product of characteristics.

As a result of the procedures for assessing the correctness and reliability of the appearance of veterinary products in accordance with the original sample, registration dossier and regulatory documentation, a conclusion is issued, which provides a detailed description of the research and the conclusions drawn from their results.
How The Supreme Court Can Improve Educational Opportunities for African American and Hispanic Students by Ruling Against Harvard College’s Use of Race Data
Authors: Kelly Genevieve
Published: June 2021

Students for Fair Admissions v. Harvard has not only exposed ways in which Harvard College’s admissions office unfairly assesses Asian American applicants, but it has also revealed that Harvard’s fixation on race per se can disadvantage the very African American and Hispanic students best positioned to bring instructive and underrepresented perspectives to the college. The facts show that Harvard’s “tips” and “one-pager” system values African American and Hispanic students for their ability to boost Harvard’s racial profile more than for their actual experiences confronting racial discrimination. This Comment explains how, by ruling against Harvard (and without overruling Grutter or Fisher II), the Court can force the college to adopt admissions policies that not only treat all applicants more fairly, but that more fully affirm African American and Hispanic applicants. This Comment also offers ways that a ruling against Harvard could benefit disadvantaged African American and Hispanic students at every grade level—whether or not they ever apply to Harvard.

La presente investigación pretende analizar a partir del caso del laurel silvestre del Parque Nacional el Chico (PNECh), la relación que existe entre esta especie no maderable y el turismo (actividad que ha sido promovida en esta área protegida desde hace más de tres décadas), a partir del análisis de su abundancia y usos en las comunidades locales. Se realizó un análisis de la abundancia de las poblaciones de la especie en zonas con turismo y sin turismo dentro del área protegida. Se utilizaron métodos etnográficos como entrevistas abiertas y semi-estructuradas para conocer los usos de la planta en las localidades aledañas a la zona y caracterizar la red de comercialización. Se documentaron, a partir de la observación participante, los usos del laurel en las festividades de Semana Santa. Se encontró que las poblaciones de laurel dentro de este espacio protegido son más abundantes en sitios sin turismo. La actividad turística no está relacionada directamente con los usos de la planta. Los usos religiosos fueron menos frecuentes, a diferencia de los casos que se documentaron en el Estado de México y otros sitios de Hidalgo, en donde el uso religioso tiene valor social y ceremonial importante. En la cadena de comercialización de la planta participan diferentes actores que la venden en mercados locales de la capital del estado, sin embargo, es en la Ciudad de México en donde se da una venta considerable. Como conclusión, la actividad turística del Parque Nacional no influye directamente en la abundancia de laurel, así como tampoco en la comercialización del mismo, en esta área protegida sus usos principales son como condimento y es ofrecido a los turistas a través de la gastronomía, pero en cantidades mínimas. En regiones aledañas al Parque sus usos están mayormente relacionados con aspectos religiosos. La comercialización se da principalmente fuera de la región.

Published: June 2021

Introduction: Pre-clerkship procedural skills training is not yet a standard across Canadian medical school curricula, resulting in limited exposure to procedures upon entering clerkship. While simulated skills training has been documented in the literature to improve performance in technical ability, anxiety and confidence have yet to be investigated despite their documented impact on performance and learning. This study therefore aims to evaluate the effect of pre-clerkship procedural skills training on medical student anxiety and confidence.

Methods: A procedural skills training program was designed based on an evidence-based near-peer, flipped classroom model of education. Ninety-two second-year medical students volunteered for the study. Fifty-six were randomized to the training group, and 36 were randomized to the control group. Students in the training group attended seven procedural skills tutorials over seven months. The control group represented the average medical school student without standardized procedural training. Student anxiety and confidence were assessed at the beginning and end of the program using the State Trait Anxiety Inventory and Confidence Questionnaires.

Results: Students who participated in the procedural skills program demonstrated greater reductions in their state anxiety and greater improvements in confidence compared to the control group.

Conclusion: Longitudinal procedural skills training in the simulation setting has demonstrated improvements in anxiety and confidence among pre-clerkship medical students. These added benefits to training have the potential to ease medical students’ transition into clerkship, while also contributing to a safer and more effective clinical experience. Therefore, future integration of standardized pre-clerkship procedural skills training within medical school curricula should be considered.

Peatland fires are a problem every year in Indonesia especially in Sumatera Island. In Riau during the dry season, there will be peatland fires that are difficult to extinguish. There are several reasons for peatland fires and this study will analyze whether cigarette butts can cause peat fires or not. In this research peat sample was dried at 35-45°C and at temperature at 115°C to reduce water content in peat samples. Cigarette butts as a trigger were prepared with a length of 30 mm and tested on a bomb calorimeter to determine their calorific values. The cigarette butts with the highest HHV (High Heating Value) were used and burned on the surface of the peat sample by adding airflow to the sample with varying flow rates. The fastest of smoldering combustion propagation velocity was obtained 785 mm/hour for vertical direction and 1336 mm/hour for horizontal direction with speed of airflow of 5 m/s. The highest temperature was obtained in the experiment of 902°C with the speed of airflow of 5 m/s.

Friction welding is a type of solid state welding where the welding process is carried out in a solid phase to combine various types of ferrous and non-ferrous metals that cannot be welded by the fusion welding method but for welding different metals the welding results are less than optimal due to cracks on the surface of the welding results and differences in mechanical properties that cause the welding result to be brittle, therefore an interlayer is used. In this study, observations were made on the process and results of the joint friction welding using dissimilar metal material between mild steel ST37 and stainless steel 201 with copper interlayer. The results of the test will be a tensile test to see the maximum tensile strength and a hardness test to see the hardness value of the interlayer variation of 0.3 mm, 0.5 mm, 1 mm and without an interlayer. The conclusions obtained are: (1) The effect of the addition of an interlayer on the rotary friction welding process includes the friction phase, the forging phase and the results of welding parameters in the form of motor power, motor angular speed, the change in specimen length is greater without using an interlayer compared to using an interlayer while the duration of welding time is greater using an interlayer than without using an interlayer. (2) The maximum tensile test results were obtained at the 1 mm interlayer at 482.43 MPa and the maximum hardness test results obtained at the 1 mm interlayer were 321.34 VHN.

Upon the announcement of lockdown of Kinshasa (The capital city of the Democratic Republic of Congo) due to increase cases of corona virus infections, a wave of fear and concern arose among the population of the city causing a massive population’s displacement towards neighboring provinces. This is to contextualize a phenomenological qualitative study exploring the social representation of COVID-19, the motivations influencing the shift of population and the discourses of the subjects on the care strategies, or “therapeutic artifacts” proposed by this population of Kinshasa. The analysis of 19 semi-structured interviews highlighted the presence of five categories of representations of COVID-19: imaginary disease, disease for businessmen, invention for demographic purposes, war between states and, divine punishment. In addition, four types of motivation have influenced the movement of the population: socioeconomic crisis, insecurity, ban of churches and, easy access to traditional treatment. This study finally shows that the fugitive population uses traditional therapies (herbalists and traditional beliefs, including prayers and sorcery) to cope with this pandemic. Improving knowledge, strengthening the communication system and interventions aimed at changing social representations causing negative images of COVID-19 are recommended.

The development of spatial differentiation of unemployment in Czechia through evolutionary and institutional approaches: the example of the Karvinsko and Jablunkovsko regions
Authors: Vrbík Filip , Netrdová Pavlína
Published: June 2021

The aim of this paper is to gain insight into the dynamics of spatial differentiation of unemployment on the municipal and microregional levels in Czechia. The spatial patterns of unemployment are quantitatively evaluated; and, based on these results, two microregions are chosen as case studies (Karvinsko and Jablunkovsko). These microregions are spatially close but underwent a totally different evolution in regional unemployment. Factors that affect different dynamics of unemployment are identified based on the analysis of their historical development and interviews with local agents. Thus, potential causes of dissimilar trajectories are revealed. The theoretical framework of the research is based on a combination of evolutionary and institutional approaches in economic geography that emphasize the role of history, continuity, local specifics and informal norms and practices in local and regional development.
Relentless Regeneration
Authors: Ryan Una S.
Published: June 2021

Regenerative Medicine is a branch of medicine holding promise for the repair of cells, tissues, and organs to effective function. Much of the field has been developed in response to damage sustained by injury and disease. However, the body is under constant maintenance with a natural ebb and flow of dying and renewing cells. In addition, cells, tissues, and organs are constantly responding to routine demands to accommodate great variations in signals and responses. Remarkable examples are the cells composing the blood vessels and airways of the lungs. The ability to regulate, maintain and respond to changes in blood pressure and gas exchange across the blood-air interface illustrates the relentless ability of our bodies to self-adjust and self-renew throughout life. Likewise, the earth in which we live is under constant change and remodeling. Natural disasters such as volcanic eruptions and earthquakes, with time, recover and become incorporated into the rhythm of daily life. Initial recovery may be brutal but in both cases, the body and the earth have an amazing power to heal.
Can Interstitial Lung Disease Be A Para-Neoplastic Syndrome?
Authors: Dutt Tiyas Sen
Published: June 2021

Interstitial lung diseases (ILD) are a group of conditions with varied etiology, clinical presentation, management, outcome and complications. Although studies have described lung cancer as a sequel of ILD, the association of ILD with non-lung malignancies or ILD presenting as a paraneoplastic syndrome of an underlying occult malignancy deserves further study. In this case series, we describe eight patients with an ILD and an associated neoplasm and discuss the different questions raised by this association.

Published: June 2021

Hutchinson Gilford progeria Syndrome (HPGS) was first described by Jonathan Hutchinson Gilford in 1897 [1]. It is characterized by characteristic facies also described as plucked bird appearance. These are reported to occur due to denovo autosomal dominant mutation in Laminin A(LMNA) gene present on 1q21.1-1q 21.3 and are rarely inherited [2]. This is to report a rare case series of two children presenting with Hutchinson Gilford progeria with ocular manifestation.

Materials and methods: The results of surgical treatment in 30 patients with oral and oropharyngeal cancer were studied. Postoperative surgical complications were analyzed according to the Clavien-Dindo classification, the causes of postoperative complications after reconstructive operations.
Results: Postoperative complications developed in 20.0% of cases and were represented by dehiscence of the wound edges, bleeding, and in the long-term period by the formation of a pharyngostomy, osteradionecrosis with a pathological fracture of the jaw. The resulting post-resection defects are inevitably accompanied by severe functional impairments: impaired opening of the mouth was noted in 36.7% of patients, impaired swallowing - in 3.3%, speech impairments - in all patients. The acoustic characteristics of speech were lower than those of a healthy person.
