RESUMO

Background: Three or more waves of COVID 19 pandemic have hit the different parts of world including India very hard, taking toll on the lives of people both in terms of morbidity and mortality. Keeping this in mind, the present study was conducted with an aim to determine the socio-demographic and clinical profile of laboratory confirmed COVID 19 cases and to determine their association with oxygen requirement and outcome of disease at the time of discharge. Methods: The present cross-sectional study was conducted on lab confirmed COVID 19 cases admitted in tertiary care hospital in Jammu from June-July 2021.Data was collected using convenient sampling method. The self-designed questionnaire used for data collection obtained information regarding socio-demographic characteristics of patients as well as clinical features of the disease. Results: Out of total 161 patients studied, 60.8% were males and 39.2% were females. Mean age was 51.2 ± 17.5 years. Comorbid conditions were present in 37.8% patients, with hypertension being the most common ( 36%). Cough, Fever, breathlessness and myalgia were the main presenting symptoms (90%, 81%, 57.7% and 56% respectively). The variables which were found to have statistically significant association with oxygen requirement and the outcome of disease at the time of discharge were age, gender and presence of co-morbidity (p <0.05). Conclusions: Advancing age, male gender and presence of underlying co-morbidity were found to be significant risk factors for the requirement of oxygen and poor outcome of the disease.

RESUMO

The emergence of multi-drug resistant (MDR) bacterial strains, which are posing a global health threat has developed the interest of scientists to use bacteriophages instead of conventional antibiotics therapy. In light of an increased interest in the use of phage as a bacterial control agent, the study aimed to isolate and characterize lytic phages from sewage effluent. During the current study, bacteriophage AS1 was isolated from sewage effluent against E.coli S2. The lytic activity of phageAS1 was limited to E.coli S2 strain showing monovalent behavior. The calculated phage titer was 3.5×109 pfu/ml. PhageAS1 was stable at a wide range of pH and temperature. The maximum stability was recorded at 37ºC and pH 7.0, while showing its normal lytic activity at temperature 60ºC and from pH 5.0 to 11.0 respectively. At temperature 70ºC, phage activity was somewhat reduced whereas, further increase in temperature and decrease or increase in pH completely inactivated the phage. From the current study, it was concluded that waste water is a best source for finding bacteriophages against multi-drug resistant bacterial strains and can be used as bacterial control agent.

Diante do crescente interesse no uso de fago como agente de controle bacteriano, o estudo visou isolar e caracterizar fagos líticos de efluente de esgoto. Durante o estudo atual, o bacteriófago AS1 foi isolado de efluente de esgoto contra E. coli S2. A atividade lítica de phageAS1 foi limitada à cepa E. coli S2, apresentando comportamento monovalente. O título de fago calculado foi de 3,5 x 109 ufp/ml. PhageAS1 foi estável em uma ampla faixa de pH e temperatura. A estabilidade máxima foi registrada a 37ºC e pH 7,0, enquanto mostrou atividade lítica normal em temperatura de 60ºC e pH 5,0 a 11,0, respectivamente. Na temperatura de 70ºC, a atividade do fago foi um pouco reduzida, enquanto o aumento adicional da temperatura e a diminuição ou aumento do pH inativaram completamente o fago. Com base no estudo atual, concluiu-se que a água residual é a melhor fonte para encontrar bacteriófagos contra cepas bacterianas multirresistentes e pode ser usada como agente de controle bacteriano.

RESUMO

Objective: This study is aimed at investigating the knowledge, practice and attitude of the patients with type-2diabetes mellitus regarding diabetic retinopathy in Saudi Arabia. Introduction: Diabetes self-management isdefined as a crucial factor in patients’ care. Many studies show that the lack of sufficient knowledge, goodpractice, and positive attitude among the patients concerning their disease and its complications is due toilliteracy. Therefore, presenting knowledge, practices, and attitudes towards the management of diabetes shouldbe done before considering any possible intervention. The materials and methods section explains the datacollection and analysis along with their limitations. In the results part, the data collected from each section areexplained and summarized in tables. In the discussion section, the results are explained and then related to theprevious studies. Then the conclusion sums up all the results found and subsequently recommends the best wayfor the future researchers to improve the results of the research.

RESUMO

Background: Scrub typhus is lesser known cause of fever of unknown origin in India. Even if there have been reports documenting the prevalence of scrub typhus in different parts of India, it is still an unknown entity, and clinicians usually do not consider it as differential diagnosis. The present study was performed to document the prevalence of scrub typhus among febrile patients in western part of Uttar Pradesh and to assess the clinical profile of infected patients on the one hand and knowledge, attitude, and practices among clinicians on the other. Materials and Methods: A total of 357 adult patients with fever of more than 5-day duration were recruited. All patients underwent complete physical examination, and detailed clinical history was elicited as per predesigned pro forma. After primary screening to rule out malaria, enteric fever, and leptospirosis infection, secondary screening for scrub typhus was done by rapid screen test and IgM ELISA. Results: Scrub typhus infection was positive in 91 (25.5%) cases. The most common symptoms among the patients were fever (100%), pain in abdomen (79.1%), pedal edema 56 (61.5%), rash 44 (48.3%), headache 44 (48.3%), vomiting 42 (46.1%), constipation 33 (36.2%), cough 28 (30.7%), and lymphadenopathy 20 (21.9%). The median values of interleukin-8, interferon-gamma, and tumor necrosis factor-alpha in healthy controls were 15.54 pg/ml, 7.77 pg/ml, and 54.1 pg/ml, respectively, while the median values of these cytokines in scrub typhus-positive patients were 21.04 pg/ml, 8.74 pg/ml, and 73.8 pg/ml, respectively. Conclusion: Our results highlight that scrub typhus infection is an important cause of pyrexia of unknown origin, and active surveillance is necessary to assess the exact magnitude and distribution of the disease.

RESUMO

This study aimed to evaluate undergraduate medical students' perceptions to Blackboard [Bb] utilization learning management systems in terms of benefits and difficulties. The study was conducted at the College of Medicine, King Saud University. A self-administered questionnaire was distributed to the students. The questionnaire consisted of three parts including demographic information, utilization of Bb and difficulties while using Bb. A total of 808 questionnaires were distributed with 42% response rate. Among the participants, 224 [65.7%] were male and 116 [34.3%] were female students. Of them, 78.1% reported "disagreement and strong disagreement" on "Bb usefulness in communicating with the instructor". However, 74.1% students reported "disagreed and strongly disagreed" on "Bb usefulness in communicating with other students", whereas majority of the students [71.8%] did not use multimedia available in Bb system. Also, 61% students agreed that there is a "lack of formal training" on the use of Bb in the college, and 37.2% students agreed that the using "Bb system is a time consuming". However, 39.2% students did not know about the Bb systems add any additional burden on the students. The disagreement trend of male and female students concerned with the Bb utility and difficulties were almost same. The finding of the study showed a poor utilization of Bb learning features. Students faced technical difficulties while using Bb. The findings of this study indicate the need of compulsory students training of any newly introduced learning management systems including Bb in the educational institute

RESUMO

Serositis [peritonitis, pleuritis, and pericarditis] can be observed in approximately 13% of patients with systemic lupus erythematosus [SLE]. However, peritoneal serositis presenting as painless massive ascites is extremely rare with only few cases been reported. Indeed, ascites in SLE has been reported to occur only when complicated by nephrotic syndrome, congestive cardiac failure, or portal hypertension. We describe herein a very unique case of SLE related serositis presenting with a massive refractory ascites, normal albumin, and absence of a clear autoimmune disorder or protein-losing enteropathy [PLE] at the time of her presentation, which only responded to a pulse course of corticosteroid. SLE was confirmed 2 years later

RESUMO

To evaluate the effects of systemic doxycycline on clinical and microbiological parameters of diabetic subjects with chronic periodontitis. This 9-month multi-center, randomized, parallel, single-blinded study was conducted from different hospitals in Riyadh, Saudi Arabia between April 2010 and December 2010. A total of 76 diabetic subjects with chronic periodontitis were randomized into 2 groups: control group [CG] received only scaling and root planing [SRP], and the treatment group [TG] receiving systemic doxycycline during the reevaluation visit 45 days after the completion of SRP. Probing pocket depth, clinical attachment level, gingival index, plaque index, and bleeding on probing were collected at baseline, 45 days after SRP, and one, 3, and 6 months after the use of systemic doxycycline. Microbiological analysis comprised the detection of Tannerella forsythia [Tf], Aggregatibacter actinomycetemcomitans [Aa], Porphyromonas gingivalis [Pg], and Prevotella intermedia [Pi] by polymerase chain reaction method. Sixty-eight [33 CG and 35 TG] subjects completed the study. Greater reduction in the population of Tf, Pg, and Pi were observed in TG compared with CG in the first month after the administration of systemic doxycycline. The TG showed a significant improvement in gingival index scores compared with the CG [p<0.05] by the end of the first and 6 months after the administration of doxycycline. Adjunct systemic doxycycline can be associated with a reduction of Tf, Pg, and Pi in the first month after the administration of doxycycline with an improvement in the GI

RESUMO

To describe the visual outcome of patients with lens subluxation [LS], including ectopia lentis [EL] due to genetic causes, who underwent surgical correction using standard selection criteria and surgical techniques in order to assess effectiveness of current LS therapy. This is a retrospective review of 17 sequential patients with LS who underwent lens aspiration between 2000 and 2012 through an anterior [limbal] or posterior [pars plana] approach at King Abdulaziz University Hospital, Riyadh, Saudi Arabia. Snellen visual acuity was converted to the logarithm of the Minimum Angle of Resolution [logMAR] equivalent for statistical analysis. All statistical comparisons were performed by t-test. This series consisted of 28 eyes with causes of LS including Marfan syndrome [12 eyes], familial EL [5 eyes], homocystinuria [4 eyes], sickle cell anemia [2 eyes], and trauma [6 eyes]. Mean visual acuity [VA] for the entire group increased from 20/200 before surgery to 20/70 after surgery [p >/= 0.01]. Post-operative VA was >/= 20/60 in all eyes that did not have complicating factors such as amblyopia, retinal detachment, and/or other ocular abnormalities. Visual outcome of limbal and pars plana approaches was statistically similar [p >/= 0.29]. Patients with genetic causes of EL had a significantly better visual outcome than other patients [p >/= 0.01]; out of these, patients with Marfan syndrome had a better visual outcome than other patients with genetic abnormalities [p >/= 0.02]. Accepted surgical criteria and techniques improved visual outcome in patients with LS. Patients with Marfan syndrome and others genetic abnormalities without ocular complications had best visual outcomes

RESUMO

To evaluate the predictive value of hyaluronic acid [HA] for the assessment of liver fibrosis and inflammation in chronic hepatitis C [CHC]. This cross-sectional study was conducted at Ziauddin University, Karachi, Pakistan from June 2006 to July 2010. Ninety-eight CHC patients, 52 [53%] males, and 46 [47%] females, with an age range of 20-60 years [mean 36.0 +/- 10.5] were recruited. Liver fibrosis was staged on a 5-point scale, F0 to F4, and inflammation was graded on a 4-point scale, A0 to A3. Patients were divided into minimal [F<2 and A<2] and significant [F >/= 2 or A >/= 2] overall disease groups. The HA was measured in the serum by ELISA. Diagnostic value was assessed through receiver operating characteristic [ROC] curve. Significant liver disease was present in 46 [47%] patients. Mean serum HA was significantly different among severity groups [p=0.001]. Area under ROC curve for overall disease was 0.716. Negative predictive value [NPV] for significant overall disease remained 71% at a low HA level of 20 ng/mL. Positive predictive value [PPV] of 85% was obtained at 60 ng/mL and 100% at 120 ng/mL. Those high levels were present in 15% and 10% of the patients. Serum HA levels showed a low NPV for significant liver disease. An acceptable PPV was found only in a small proportion of the patients. Hyaluronic acid may not be regarded as a reliable marker for making treatment decisions

RESUMO

To determine the lung function among Saudi type 1 diabetes mellitus [T1DM] children and adolescents. This study was conducted in the Department of Pediatrics, Division of Pediatric Pulmonology and University Diabetes Centre, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia from December 2008 to July 2010. A group of 52 [26 male and 26 female] volunteer T1DM children were recruited with an age range from 8-14 years [mean 12.05 +/- 1.42 years], mean duration of disease of 5.25 +/- 0.47 years, and mean glycosylated hemoglobin of 11.27 +/- 0.31%. Spirometry was performed on an Electronic Spirometer [Compact Vitalograph, Stockwell, London, UK]. Pulmonary function in children with diabetes showed significant lower mean values of actual lung function parameters forced vital capacity [FVC], peak expiratory flow [PEF], and maximum mid expiratory flow rate [MMEF] compared to their predicted values. However, there was no significant reduction in the actual forced expiratory volume in the first second [FEV1], and FEV1/FVC% compared to their predicted values. The actual lung function data among Saudi T1DM children and adolescents showed significantly lower values of FVC, PEF, and MMEF compared to the predicted lung function data

RESUMO

To determine and analyze the frequency of periodontopathogens in microbiological monitoring of diabetic patients with periodontitis. This cross-sectional study included 352 diabetic patients with periodontitis who were registered at Riyadh Armed Forces Hospital, King Faisal Specialist Hospital and Research Centre, King Abdul Aziz Medical City, Naval Base Hospital, and Sultan Bin Adulaziz Humanitarian City, Riyadh, Kingdom of Saudi Arabia from July 2004 to August 2008. Microbiological analysis comprised the detection of Bacteroides forsythus [Bf], Aggregatibacter actinomycetemcomitans [Aa], Porphyromonas gingivalis [Pg], and Prevotella intermedia [Pi] by polymerase chain reaction method. The mean age of patients was 54.4 +/- 0.67 [range: 21-80 years]. There were 214 [61%] males and 138 [39%] females. Among the study population, 36 [10%] had type 1, and 316 [90%] patients had type 2 diabetes. The results showed that 55.6% of patients had Bf, 51.7% had Az, 63.7% had Pg, and 6.1% had Pi. The frequencies of periodontopathogens were higher in males than females in all age groups. The risk of periodontopathogens Bf were found higher level in 41-50 age group, Aa in 51-60, Pg in 51-60, and Pi in 31-40 age groups. This study found that the frequencies of periodontal pathogens Bf, Aa, and Pg were higher than Pi in diabetic patients with periodontitis

RESUMO

Orbital myositis is a rare non-granulomatous inflammatory process within the orbit. Grave's disease and lymphoproliferative disorders are considered the most common cause of orbital myositis. The idiopathic form should be considered after exclusion of known causes or associations. Isolated orbital myositis is a very rare form of this disease. We report a case of an isolated lateral rectus myositis to draw the attention of physicians to this condition, as prompt treatment in our patient resulted in complete recovery

RESUMO

To investigate the effects of electromagnetic field radiation generated by mobile phones on serum testosterone levels in Wistar albino rats. This experimental interventional control study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia during the period December 2006 to April 2008. A total of 34 male Albino rats [Wistar strain], 2 months of age, weighing 150-160 gm were used for the experiment. These animals were divided into 3 groups. The first group containing 6 rats was assigned as a control group. The second group containing 14 rats was exposed to mobile phone radiation for 30 minutes daily and the third group containing 14 rats was exposed to mobile phone radiation for 60 minutes daily for the total period of 3 months. At the end of experimental period, blood was collected into the container, and serum testosterone was analyzed using double-antibody radioimmunoassay method by Coat-A-Count. Exposure to mobile phone radiation for 60 minutes/day for the total period of 3 months significantly decrease the serum testosterone level [p=0.028] in Wistar Albino rats compared to their matched control. Long-term exposure to mobile phone radiation leads to reduction in serum testosterone levels. Testosterone is a primary male gender hormone and any change in the normal levels may be devastating for reproductive and general health

RESUMO

Respiratory muscle endurance is of interest in pulmonary, critical care and many other areas of medicine. The maximal voluntary ventilation [MVV] test is an objective dynamic method for measuring the working capacity of respiratory muscles. Therefore, we designed the present study to determine the effect imposed by diabetes mellitus on respiratory muscle endurance in Saudi diabetic patients. We conducted this study in the Department of Physiology, College of Medicine, King Khalid University Hospital and Diabetic Centre, King Abdul-Aziz University Hospital, Riyadh, Saudi Arabia during the year 2002-2004. In this study, we recruited 39 male diabetic patients and equal number of control subjects and all participants were non-smokers with age range of 23-71 years. The subjects were matched for age, height and weight. We determined the respiratory muscles endurance by a direct MVV test during inspiratory and expiratory phases of respiration by using a MP-100 student Bio Pac system and compared the results using a paired t-test. In inspiratory and expiratory phases of respiration, diabetic patients showed a significant reduction in the mean values of direct MVV test [p<0.001] relative to their matched controls. We conclude that in diabetic patients the respiratory muscles endurance is impaired by a decreased in MVV values. This decline in MVV further showed that the diabetic patients have a reduced inhaled and exhaled volumes during consecutive breaths

RESUMO

To study the effects of type 2 diabetes mellitus on lung function and to determine its severity in relation to duration of disease. We conducted this study in the Department of Physiology, College of Medicine, King Khalid University Hospital and Diabetic Centre, King Abdul-Aziz University Hospital, Riyadh, Saudi Arabia during the year 2002 -2004. A group of 32 apparently healthy volunteer male type 2 diabetic patients were randomly selected with an age range from 24-73 years. We matched the diabetic patients with another group of 40 control healthy male subjects in terms of age, height, weight, and socioeconomic status. Both groups met with exclusion criteria as per standard. Spirometry was performed on an Electronic Spirometer [Schiller AT-2 Plus, Switzerland] and results were compared using the 2-tailed student t-test. Diabetic patients showed a significant reduction in the forced vital capacity [FVC], forced expiratory volume in one second [FEV1] and peak expiratory flow [PEF] relative to their matched controls. However, there were no significant difference in the forced expiratory ratio [FEV1/FVC%] and middle half of the FVC [FEF 25-75%] between the groups. Lung function in type 2 diabetic patients is impaired by a decrease in FVC, FEV1 and PEF, as compared to their matched controls. Stratification of results by years of disease showed a dose-response effect on lung function

RESUMO

To determine the effects of type 1 diabetes mellitus on lung function and its gravity in relation to the duration of disease. We carried out this study in the Department of Physiology, College of Medicine and Diabetic Center, King Abdul-Aziz University Hospital, King Saud University, Riyadh, Saudi Arabia during the period 2003-2004. We randomly selected a group of 27 apparently healthy volunteer Saudi male type 1 diabetic patients with age ranging from 19-70 years. We matched the diabetic patients with another group of 27 control healthy male subjects in terms of age, height, weight and socioeconomic status. Both groups met with exclusion criteria as per standard. We performed spirometry on an Electronic Spirometer [Schiller AT-2 Plus, Switzerland] and compared the results by a student t-test [2-tailed]. Type 1 diabetic patients showed a significant reduction in the forced vital capacity and forced expiratory volume in one second [FEV1] relative to their matched controls. However, there was no significant difference in the forced expiratory ratio, forced expiratory flow; forced expiratory flow and peak expiratory flow [PEF] between the groups. It is concluded that lung function in type 1 diabetic patients is impaired by a decrease in FVC and FEV1 as compared to their matched controls. Additionally, the years of disease showed a dose-response effect on lung function
