No presente trabalho, selecionou-se o hidrociclone concentrador HOII, obtido por Garcia (2018), para que fosse realizada uma simulação via fluidodinâmica computacional (CFD) do escoamento em seu interior. Para isso, construiu-se a geometria e a malha computacional do equipamento no software GAMBIT® e a simulação foi realizada pelo software ANSYS Fluent usando o modelo Reynolds Stress Model (RSM) associado ao modelo Volume of Fluid (VOF). Assim, a razão de líquido e o número de Euler calculados pela simulação foram comparados aos resultados experimentais e calculados por modelos empíricos, obtidos por Garcia (2018). Os resultados mostram que o modelo CFD possui uma capacidade preditiva satisfatória das respostas do HOII. Além disso, os resultados da simulação também mostram que o escoamento no interior do HOII envolve a formação de um air core estável e resulta em um movimento axial descendente somente nas proximidades das paredes do hidrociclone. Tais constatações explicam a baixa razão de líquido e alto poder de concentração do HOII.

Este trabalho compreende a atuação da mulher trabalhadora nos dias atuais. Questionou-se a desigualdade entre homens e mulheres na atuação profissional da engenharia civil e considerou, por fim, que os tratamentos desiguais são reflexos de uma sociedade que ainda está ancorada nos discursos do século XIX, que entendiam mulheres como corpos frágeis biologicamente e os homens o seu oposto, sendo fortes. Ao estudar algumas leis municipais, percebeu-se que o poder público tenta amenizar a distinção a partir de legislação específica, mas no cotidiano a prática esbarra no comportamento, que ainda legitima a distinção de gênero.

Authors: Gontijo Anne do Carmo Mendes , Borges Sheila
Published: March 2022

Este trabalho objetivou avaliar o estado nutricional de portadores de doença renal crônica (DRC) em hemodiálise de um hospital público do Distrito Federal. Foi realizado um estudo observacional, do tipo transversal e analítico, na unidade de nefrologia do Hospital Regional de Taguatinga (HRT), da Secretaria de Saúde do Distrito Federal. A pesquisa ocorreu em indivíduos diagnosticados com DRC, de ambos os sexos, em realização de hemodiálise por mais de três meses. Foram coletados dados sobre sexo, idade, albumina, peso pós sessão, altura, circunferência do braço e dobra cutânea tricipital. Foram calculados: índice de massa corporal (IMC), circunferência muscular do braço e área muscular do braço corrigida. A classificação do estado nutricional também foi realizada por meio da avaliação subjetiva global de sete pontos (ASG-7p). Inicialmente, os dados foram analisados por meio de estatística descritiva, com o uso de média, mediana, desvio padrão ou frequências. Para as variáveis contínuas, utilizou-se o teste de Shapiro-Wilk, a fim de verificar a normalidade das variáveis. A correlação entre as variáveis foi verificada por meio dos coeficientes de Pearson e Spearman, com o software Statistical Package for the Social Sciences (SPSS), versão 23.0. Foi considerado um nível de significância de 0,05. A amostra foi constituída de 40 indivíduos, idade média de 45,55±10,06 anos, sendo 60% (n=24) do sexo masculino e 40% (n=16) do sexo feminino. A desnutrição foi verificada em 50% (n=20) dos participantes pelo IMC, 57,50% (n=23) pela circunferência muscular do braço, 65% (n=26) quando avaliado a área muscular do braço corrigida e 47,50% (n=19) quando aplicado a ASG-7p. A albumina estava dentro dos valores de normalidade para a maioria da amostra estudada 72,50% (n=29). A desnutrição proteico calórica é bastante prevalente nos portadores de DRC em hemodiálise. Nesse estudo, o método mais sensível para diagnóstico de desnutrição foi a área muscular do braço corrigida, porém todos os métodos empregados, sejam subjetivos ou objetivos, tiveram sensibilidade para detectar desnutrição. Por isso é imprescindível que utilizemos todas as ferramentas disponíveis para realizar avaliação nutricional desses indivíduos.

Objective: Osteoradionecrosis (ORN) of the jaws is an important side effect of head and neck cancer radiotherapy.  The main objective of this work was to evaluate the expression of RANK, RANKL and OPG proteins, markers of bone remodeling, in rats submitted to radiotherapy. Material and Methods: Six-month-old male Wistar rats were divided into two groups: Irradiated group (IR), which received a single dose of 20 Gy in the jaw and after seven days had their three left mandibular molars extracted; Control group (C), which didn’t receive radiation, but underwent the same procedures.   Twenty one days after the dental extractions, the animals were euthanized and their mandibles were removed for analysis. The volume density (Vv) of immunoexpression of RANK/RANKL/OPG was quantified by stereology. The bone volume ratio (BV/TV), the trabecular thickness (Tb.Th), the trabecular separation (Tb.Sp) and the trabecular number (Tb.N) were analyzed by microtomography (Micro-CT). Results: Vv of immunoexpression of RANKL and OPG were, respectively, 53% higher and 50% lower in IR animals compared to C group (p0.05). Micro-CT showed that in the IR animals there was a reduction of the bone mass compared to the C animals. BV/TV and Tb.Th were 33% and 38% lower, respectively, in the IR animals (p0.05), while Tb.Sp was 37.5% higher in these animals (p0.05). Conclusions: Ionizing irradiation in a single high dose, followed by dental extractions promoted ORN in mandibular bone in rats, together with changes in the markers of bone remodeling RANK and OPG.

A 48-year-old patient, male, previously healthy, started migraine with aura at 46 years old of age. After two years, he evolved with the first episode of Ischemic Stroke, with motor and sensory deficit of the left hemibody with partial recovery of symptoms. Stroke protocol and etiological investigation were performed without alterations. Two months later, he presented convulsive crisis requiring the use of medication still for control. It evolved with mild cognitive impairment and depression. Three years later, he had a new episode of stroke, performed Magnetic Resonance Imaging of the Skull, evidencing areas of hypersignal in T2/ FLAIR in the poles of the temporal lobes, also diffusely affecting the supratentorial white substance, with small focal alterations of a means suggestive of small ischemic sequelae, also present in the callous body, deep gray substantial and brainstem, of probable vascular nature. Thus, CADASIL (Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) was suspected, requested genetic testing showing alteration in the DNA sequence of the NOTCH-3 gene, Allelo1: t C transition, nucleotide 514; códon 146; exchange of the amino acid cysteine Arginine. Allelo 2: Transition C G, nucleotide 1272; códon 398; no amino acid exchange, confirming diagnostic suspicion. The patient is monitored in the neurology outpatient clinic with multidisciplinary rehabilitation therapy, secondary prevention treatment for stroke, antidepressant medication and topiramate for migraine treatment.

Published: March 2022

A male patient presents with urinary incontinence with worsening in the last year, shock sensation, symmetrical weakness and involuntary spasms in the lower limbs. He currently required double support to ambulate and had no sphincter control. Neurological examination demonstrated lower limb hypertonia and spastic paraplegia with severe impairment of deep sensation and painful muscle spasms. The patient and had normal body mass index and laboratory tests excluded endocrinopathies. MRI showed myelopathy caused by hyperintense tissue with suppressed T1 signal in the epidural space, representing fatty tissue and extensive hyperintensity in the upper portion of the thoracic spinal cord. Axial T2-weighted imaging confirmed fatty tissue in the epidural space between the T3 and T7 levels, promoting markedly narrowed dural sac and spinal cord compression. The case was then compatible with idiopathic lipomatosis and surgery was indicated. The patient did not agree and was lost to follow-up.

Published: March 2022

A 42-year-old male patient admitted to our service with a history of progressive and symmetrical weakness, paresthesia of the lower limbs, weight loss and urinary retention for about 8 months. Physical examination demonstrated poor general condition, lower limb edema, hepatomegaly and digital clubbing. Neurological examination showed a polyneuropathic pattern, with hypoesthesia and absence of deep reflexes of the lower limbs. Initial laboratory investigation demonstrated erythrocytosis and thyroid and adrenal dysfunction in addition to hypergammaglobulinemia. CSF analysis, due to the clinical suspicion of chronic inflammatory demyelinating polyneuropathy, resulted in protein-cytological dissociation. PIDC was hypothesized to be due to light-chain disease, but for this association we supplemented with bone marrow analysis and whole-body CT scan, which showed 4% atypia in plasma cells and osteolytic and osteoblastic lesions in the vertebro-costal region between the 8th and 9th vertebrae. Subsequent biopsy confirmed plasmacytoma. He performed autologous bone marrow transplantation, but evolved with infectious complications and died within 3 months.

Patients in Palliative Care (PC) represent a public whose demand is great for speech therapy, and because there is no standardized instrument for assessing the swallowing of people in COP, the Protocol for Evaluation of Dysphagia in Palliative Care (PADICUP) was elaborated. However, it had not been applied in patients. This study aimed to analyze the feasibility of PADICUP in patients of a palliative care clinic in the city of Belém, PA. A quantitative cross-sectional approach was carried out with 30 participants from April to October 2019. The data obtained in the evaluations through the protocol were organized in spreadsheets and submitted to the percentage and statistical analysis using the correlation of Pearson. Among the studied public, as the main complaints observed during screening were weight loss (97%), xerostomy (77%) and clearing during feeding (68%). Regarding the evaluation with PADICUP, only 77% of the patients were able to be evaluated with oral diet in some consistency, being oral transit time decreased, vocal quality altered, reduced laryngeal elevation, multiple swallowing and oral cavity residue, the most altered manifestations. Patients with PC present significant changes in swallowing and need a qualified and assertive speech therapy support, and PADICUP is a feasible instrument to be used for this purpose, since it covers the demands and needs of patients receiving this care.

Published: March 2022

A efusão pleural é caracterizada pelo acúmulo de líquido dentro do tórax, uma alteração comum na clínica de felinos. O quilotorax é uma das causas da efusão pleural, onde há acúmulo do quilo na cavidade torácica. Está frequentemente associado às causas primárias como neoplasia, cardiopatias, peritonite infecciosa felina entre outras causas. Em quadros onde não são observadas ou diagnosticadas causas primárias temos o quilotorax idiopático. Este não apresenta predileção de idade. Os sinais clínicos apresentados podem envolver desde apenas tosse leve e esporádica a dispneia, mucosas cianóticas, posição ortopneica, desidratação, entre outros que podem depender da causa da efusão. Os meios de diagnóstico que podem ser utilizados incluem radiografia, ultrassonografia ou tomografia torácica. Após o diagnóstico definitivo, o tratamento é direcionado a etiologia, levando a redução da formação da efusão, podendo levar o paciente a cura clínica, ou a estabilização do quadro. O tratamento a ser oferecido será definido de acordo com a sintomatologia do animal. Em casos de desconforto respiratório a oxigenoterapia deverá ser iniciada o quanto antes para a estabilização do paciente, e vários métodos podem ser empregados. Já no caso de pacientes crônicos a terapia medicamentosa deverá ser estabelecida, utilizando fármacos que irão diminuir a formação do fluido torácico trazendo maior expectativa e qualidade de vida para o paciente, como por exemplo, a rutina. O tratamento cirúrgico envolve a ligadura do ducto torácico. Nesse trabalho objetivou-se relatar um caso de quilotórax em um felino, bem como os seus achados clínicos, radiográficos, laboratoriais e o acompanhamento do tratamento clínico realizado com rutina.

Suplementação para bovinos de corte na estação chuvosa: revisão / Supplementation for beef cattle during the rainy season: a review
Authors: Ribeiro Anna Carolina de Carvalho , Barbero Rondineli Pavezzi
Published: March 2022

A bovinocultura de corte é uma importante atividade econômica no Brasil, e a carne bovina nacional exportada abastece significativa parcela do mercado mundial. A pecuária de corte no Brasil é caracterizada pela produção em pastagens. As estações climáticas impactam na produção e qualidade da forragem, sendo que na estação chuvosa temos maior quantidade e qualidade do pasto. Bovinos consumindo apenas forragem mesmo na época das águas podem não ter suas exigências nutricionais atendidas para elevado desempenho, e o uso de suplementos pode gerar incrementos de produtividade. O objetivo do material é abordar os aspectos gerais da suplementação de bovinos de corte em pastagens na estação chuvosa. Dados da literatura apontam que a suplementação de bovinos a pasto no período das águas proporciona maior ganho de peso e produtividade. Em pastos bem manejados e com boa composição bromatológica, proteína tende não ser limitante ao desempenho animal. Nesta situação, o fornecimento de suplementos energéticos na quantidade de 0,3 a 0,6% do peso corporal pode resultar em ganho de peso adicional. Ainda, o fornecimento de suplementos na estação chuvosa proporciona exploração de elevada taxa de lotação sem impactar no ganho de peso dos animais. O ajuste da suplementação em função da composição química e oferta de forragem no período das águas pode resultar em maior eficiência de produção na pecuária de corte. Ainda, o contexto mercadológico e econômico deve ser considerado no planejamento da suplementação em pastagens.

Smoothing Filter With a Variation of Coefficients for Tracking a Maneuvering Aerodynamic Target
Authors: Aparovich U. A.
Published: March 2022

The article offers a new filter for tracking a maneuvering aerodynamic target. During the process of the filter synthesis, three main requirements were considered: the filter must provide a minimum smoothing error in the areas without maneuver; the filter should ensure the minimum possible errors and emissions of smoothing error during the maneuver; filter must not contain additional constants, which take into account, for example, the value of input errors, parameters of target maneuver, period of information modification and so on. In order to meet these requirements a two-fold adjustment (variation) of the coefficients smoothing was used in accordance with the deviation of the coordinate of the newly measured position of the target (mark) from the extrapolated position. The variation is performed in accordance with the selected function, while the smoothing step acquires a certain conditional value. The proposed filter modelling has been performed. Received by modelling values of smoothing errors were compared with smoothing errors of other filters, described in scientific literature. The comparison results demonstrate a significant decrease in smoothing of the root mean square errors of coordinates and velocity in the proposed filter in comparison with other samples; with according to main requirements, any “tunes” in proposed filter were not used.
Fundamentals of the Theory of a Hydrogen Atom for Problems of Synthesis of Quantum-Electronic Circuits
Authors: Kabiak I. P.
Published: March 2022

On the basis of the unconventional concept of the formation of the line spectrum of the hydrogen atom, an equation is obtained that is necessary for computer calculations of the energy emitted by an electron during the transition from a certain current energy level rλ,n to the receiver radius r0. The obtained solution of the energy equation made it possible to derive the formal relations necessary for calculating the values of the radii of the levels of the hydrogen atom and, accordingly, the velocities of the electron in these orbits. The applied aspect of the considered methodology consists in using the results of the performed calculations for the problems of synthesis and analysis of quantum-electronic circuits.
Large Signal Performance of the Gallium Nitride Heterostructure Field-Effect Transistor With a Graphene Heat-Removal System
Authors: Volcheck V. S. , Stempitsky V. R.
Published: March 2022

The self-heating effect exerts a considerable influence on the characteristics of high-power electronic and optoelectronic devices based on gallium nitride. An extremely non-uniform distribution of the dissipated power and a rise in the average temperature in the gallium nitride heterostructure field-effect transistor lead to the formation of a hot spot near the conductive channel and result in the degradation of the drain current, power gain and device reliability. The purpose of this work is to design a gallium nitride heterostructure field-effect transistor with an effective graphene heat-removal system and to study using numerical simulation the thermal phenomena specific to it. The object of the research is the device structure formed on sapphire with a grapheme heat-spreading element placed on its top surface and a trench in the passivation layer filled with diamond grown by chemical vapor deposition. The subject of the research is the large signal performance quantities. The simulation results confirm the effectiveness of the heat-removal system integrated into the heterostructure field-effect transistor and leading to the suppression of the self-heating effect and to the improvement of the device performance. The advantage of our concept is that the heat-spreading element is structurally connected with a heat sink and is designed to remove the heat immediately from the maximum temperature area through the trench in which a high thermal conductivity material is deposited. The results of this work can be used by the electronics industry of the Republic of Belarus for developing the hardware components of gallium nitride power electronics.
Heuristic Model of Forecasting of Operating State of Semiconductor Devices
Authors: Kaziuchyts V. O. , Borovikov S. M. , Shneiderov E. N.
Published: March 2022

The threshold logic method used for electronic products when assessing their reliability in the form of predicting the performance class of products for a given operating time (K1 is a class of operable ones, K0 is a class of inoperable copies) provides for the transformation into a binary code of informative parameters obtained at the initial moment of time, and allows to build a forecasting model in the form of a table showing which code combinations correspond to the instances of the K1 class. The use of a binary transformation simplifies the forecasting procedure, but the reliability of the predictions is slightly reduced. It is relevant to obtain a forecasting model that has the simplicity of its application and provides a higher reliability of forecasting a class of products than with a binary transformation of parameters. On the example of bipolar transistors of the KT872A type, the regularities of electrical parameters used as informative ones are established, and for their transformation into a code, it is proposed to consider three areas of parameter change: the first area is the range of values between the mathematical expectations obtained separately for instances of the classes K1 and K0; the other two areas are the parameter values to the left and right of this range. Parameter values falling within the range are assigned the R code (from the word Range), outside the specified range - the code 1 (one) or 0 (zero), depending on the pattern of the informative parameter. It is explained how to convert parameters to codes 1, 0 and R and get a prediction model in the form of a logical table built from these codes. Basing on the example of the investigated transistors, it is shown that the proposed heuristic model provides the best forecasting results, practically keeping the simplicity of the basic method of threshold logic.

Published: March 2022

Nanoimprint lithography is a highly productive process and has an advantage in its resolution of printed patterns. In this paper, inorganic materials are imprinted using mixtures of nanopowders and polymer binder as starting materials. In our previous work, line-and-space patterns with the smallest pitch of about 8 μm were shown on sintered ceramic sheets using ceramic powders with the smallest particle size of about 100 nm. In this study, we prepare alumina powders with an average particle size of about 100 nm and five kinds of molds with line-and-space patterns with line widths from 10 μm to 250 nm. The line-and-space patterns were observed on all sintered samples. Although the patterns were not clear on the finer patterns, this result is remarkable. Also, we discuss how the pattern was affected by mold size and particle size.

Although there is no denitive evidence that coronavirus disease 2019 (COVID-19) affects the kidneys adversely, amongst those who develop
severe COVID-19 infection and require hospitalization, acute kidney injury (AKI) was reported. Here, we report the clinical outcome associated
with AKI in a 22-year-old woman with conrmed COVID-19 infection with no prior history of renal malfunction. The AKI was identied during
intensive care unit (ICU) course with the median creatinine and blood urea values of 7.7 mg/dL (normal value: 0.6-1.2 mg/dL) and 142 mg/dL
(normal value:05-20 mg/dL), respectively. The renal function of patients hospitalized with COVID-19 infection needs to be monitored regularly to
intervene as early as possible and to prevent the development of AKI and further kidney complications.
A RANDOMISED COMPARITIVE STUDY OF EFFECTS OF ORAL GABAPENTIN AND ORAL CLONIDINE ON PRE - OPERATIVE ANXIOLYSIS AND ATTENUATION OF STRESS RESPONSE TO ENDOTRACHEAL INTUBATION
Authors: Karekal Avinash , Ladhad Dharmesh
Published: March 2022

BACKGROUND AND AIMS : A prospective,Randomized,comparative study was done to compare the effects of Clonidine (300μg) and
Gabapentin (800mg) given orally as premedication in causing anxiolysis and attenuating the stress response to intubation in patients of ASA I/II
category undergoing elective surgery.
MATERIALS AND METHODS : About 60 Adult patients (18-60 yrs) of physical status ASA I & II scheduled to undergo elective surgical
procedures were divided into two groups of 30 each allotted randomly and labelled Group A and Group B.The Group A received 300μg clonidine
and Group B received 800mg Gabapentin orally 90-120min before induction of Anaesthesia.The Heart rate, Systolic blood pressure,Diastolic
blood pressure and Mean arterial pressure were recorded for baseline( before induction ) and at 0,1,3,5,10 min of intubation.The VAS scores were
noted before shifting to Operation theatre and before induction of anaesthesia.
RESULTS : The Groups were matched for Age,Sex,Weight and for time of induction of anaesthesia and intubation.VAS score before induction
was better for clonidine group than for Gabapentin group.The attenuation of stress response to Endotracheal intubation was better with clonidine
group than with gabapentin group (P<0.05).
CONCLUSION : Oral clonidine (300µg) provided better anxiolysis and attenuation of stress response to endotracheal intubation than oral
Gabapentin (800mg) when used for premedication.
“MEDIAN ARCUATE LIGAMENT SYNDROME’’ -A RARE CASE REPORT
Authors: Varshney Shuchi , Prasad Dinesh
Published: March 2022

Background: The median arcuate ligament passes superior to the origin of the celiac artery and is a continuation of the posterior diaphragm that
wraps over the aorta. If it lies too low on the aorta or if the origin of celiac artery is higher in location, the ligament may cause symptoms of
abdominal pain related to compression of the celiac artery.
Case Report: An abdominal ultrasound in a 20-year-old woman with longstanding abdominal pain after eating and Computed tomography
angiography of the abdomen showed stenosis of the origin of the celiac artery and conrmed the diagnosis of median arcuate ligament syndrome.
Laparoscopic release of the median arcuate ligament resulted in relief of the patient's symptoms.
Conclusion: The diagnosis of median arcuate ligament syndrome should be considered in patients with postprandial abdominal pain that does not
have a clearly established etiology.

Published: March 2022

Single complete denture treatment option is a challenging as there are chances of prosthetic failure because the plane of occlusion will always be disturbed. A correct plane of occlusion is the key to success. To correct the plane different techniques have been described in literature. But there are short comings in each technique. To counter the short comings modications were needed. Those modications are described in following article from which satisfactory results have been obtained.
HEMORRHOIDECTOMY WITH HARMONIC SCALPEL VS CONVENTIONAL HEMORRHOIDECTOMY
Authors: Sharma Rakesh , Singh Amarbir , Soni Abhinav
Published: March 2022

Background: Hemorrhoidal disease is one of the most frequently encountered anorectal conditions in the clinical practice. A variety of
instruments including circular staplers, harmonic scalpel, laser, and bipolar electrothermal devices are currently used when performing
hemorrhoidectomy grades III and IV.
Objective:This study compares outcomes between hemorrhoidectomy performed with harmonic scalpel and conventional methods.
Materials and methods: A prospective randomized study of consecutive 30 patients who underwent hemorrhoidectomy between January 2020
and October 2021. Patients were randomly enrolled in two different groups. Group I consisted of 15 patients who underwent hemorrhoidectomy
using an ultrasonic scalpel device (harmonic) and group II with 15 patients who had conventional hemorrhoidectomy.
Results: The patients' demographics data and clinical characteristics were similar in both groups. The harmonic group had a marked reduction in
operative time, nal healing time, time to return to normal physical activity, intra operative blood loss and post-operative pain.
Conclusion: Harmonic scalpel hemorrhoidectomy appears to be a better procedure for symptomatic grades III and IV hemorrhoids with ease of
operating due to marked reduction in operative time, nal healing time, time to return to normal physical activity, intra operative blood loss, postoperative pain and patient acceptance. Long-term follow-up with larger scale studies is required.

Published: March 2022

Menopause is the stage experienced by every woman around her middle age. Fraught with many uncertainties regarding physical and
psychological changes, diet, nutritional supplements and exercise or physical activity, a woman is confused and is at loss of taking correct decisions
regarding things which are benecial for her.
Aim:To determine if Indian post-menopausal women are aware about benets of physical activity or complications due to lack of physical activity.
Methodology: A total of 160 Post-menopausal Indian women aged between 45-65 yrs were given a questionnaire in order to assess their level of
awareness regarding physical exercise and calculating the level of physical activity performed.
Result: Data was analyzed and interpreted with the help of Google spreadsheet. Women were not much interested about performing physical
exercise. Most of them belonged to the pre-obese category.
Conclusion:Lack of awareness regarding physical exercise was seen among many women who performed low level of physical activity
A STUDY OF CORRELATION OF THE PSYCHIATRIC MORBIDITIES WITH THE DURATION OF ILLNESS IN DERMATOLOGICAL DISOR-DERS
Authors: Singh Priyanka , Mahmood Nasir
Published: March 2022

Background: Skin has a special place in psychiatry with its responsiveness to emotional stimuli and ability to express emotions such as anger, fear,
shame and frustration.
Aim and objectives: 1. To study the distribution of psychiatric morbidities according to the duration of dermatological disorders.
2. To study the correlation between the duration of dermatological disorders with type of psychiatric morbidity.
Results: Patients having dermatological disorder for up to 1 month were not diagnosed of having any psychiatric morbidity. Maximum psychiatric
morbidity was when the duration of illness was for more than 1 year. Out of 33 patients suffering from dermatological disorders for more than one
year 22 (66.66%) patients had psychiatric illness with a statistically signicant Pvalue of 0.0011. This was followed by patients having illness for 6
months to 1 year. 4 patients (26.66%) were diagnosed as having psychiatric morbidity. p value was signicant and was 0.0043.The patients having
illness from 1 to 6 months did not have any signicant amount of psychiatric morbidity. Depression has strong positive correlation with all the
duration intervals that are more than 1 month. Maximum correlation is with the durations more than 1 year. Dysthymia has positive correlation
only with cases having duration more than 1 year of age. Factor C, suicidality also has signicant positive correlation with the illness having a
duration of more than 1 year.
Conclusion: The present study suggests that chronicity and long standing dermatological disorder has an impact on mental health of the patient.
High chances of disgurement and long duration of treatment may also contribute to the increase in the chances of mental illness.

Background: Fibroids most common benign tumors arising from the myometrium of the uterus, was found that women with broids had
signicantly higher levels of serum HDL-C compared with control groups.
Aims : To compare the mean serum cholesterol level; mean HDL-C level andmean LDL- C level in patients with uterine broids with the control
group.
Methods: This cross sectional study was conducted after taking consent from200 women in the age group of 30-50 years . Out of which 100
females with sonographic diagnosis of uterine broid were taken up as cases and 100 females in similar age group,demographically matched with
no broids as control. Comparative study on lipid prole of both the group analysed.
This study was conducted after receiving approval from institutional ethical committee .
Results: In our study there was strong direct signicant correlation between largest broid volume (3cc) and HDL-C level (mg/dl) i.e. a p value of
0.0001and a r value of 0.671; clearly establishing the fact that patients with higher levels of HDL-C tended to have larger broids.
Conclusion :All these ndings more favourable lipid prole in broid group, lower atherogenic index and the strong direct positive correlation.
