RESUMO

Purpose: To obtain epidemiological data on children with ocular morbidity attending a nodal district early intervention center (DEIC). Methods: After parental consent, we recruited children with ocular morbidity. After detailed history and clinical evaluation, along with pediatric consultation and relevant neuro?radiological and ancillary investigation, information was entered in a pretested proforma: especially looking for perinatal morbidity, including developmental delay (DD). Visual acuity (VA) was assessed by age?appropriate means by an ophthalmic assistant trained to work with children with special needs. We diligently looked for strabismus and performed dilated ophthalmoscopy. Using JASP, we summarized data as means and proportions and reported 95% CIs. We explored the association of disability percentage with possible predictor variables using regression. Results: We enrolled 320 children, with a mean age of 34.43 ± 31.35 months; two?thirds were male; one?third belonged to lower socioeconomic status (36%), with most parents being illiterate. The mean presenting VA was 1.8 logMAR for both eyes, range: 0 to 3. Sixty?one percent were hyperopic and 27% were myopic. High refractive error, (>±6D) occurred in nine; anisometropia in one; strabismus in 149, mostly esotropia; congenital cataract in 25, whereas 63 had abnormal fundus. Seventy?six received a diagnosis of cerebral visual impairment (CVI). On multivariate linear regression (MLR), younger age, presence of DD, and CVI significantly predicted a higher disability percentage. Logistic regression revealed that statutory disability is likely associated with DD (odds ratio [OR]:13.43); whereas older age was protective (OR: 0.977). Conclusion: Our study suggests that in DEIC children with ocular morbidity, younger children, and the presence of DD significantly predict both greater disability and the likelihood of statutory levels

RESUMO

@#Introduction: Binaural beats (BB) provisions alpha and gamma have been suggested to modulate working memory (WM), while white noise (WN) acted as a control condition. Methods: The current study overlays WN on alpha and gamma tones to study its modulating role on WM performance. A block-design n-back task paradigm used to determine the effect of load on embedded BB on WM performance using functional magnetic resonance imaging. Results: Six young adults (3 males and 3 females) with mean age of 23.5 ± 0.84 within the Kota Bharu vicinity participated in the study. A repeated-measures ANOVA (p<0.05) on response accuracy indicate medium effect size on condition (η2 =0.420), and large effect sizes on groups (η2 = 0.388) and load (η2 = 0.487). The potential practical difference is more evident on low- (0-back) and high-load (3-back). GWN provision marginally excels, implying its entrainment may benefit WM processing. A repeated-measures ANOVA (p<0.05) on reaction time (RT) implied a large effect size on all variables (condition: η2 =0.065, groups: η2 =0.227 and load: η2 =0.169). It was observed that BB exposure elicits a slow processing speed which worsens RT. The neural correlates suggest activated regions in GWN and AWN are associated with attentional mechanisms and WM processes. Conclusion: Preliminary findings indicate both embedded BB has a potential to improve WM performance with the cost of slower processing speed. GWN provision modulates attentional mechanisms benefiting WM performance and AWN may enhance performance in extreme ends of WM load.

RESUMO

@#Traumatic gallbladder perforation is an unusual but potentially life-threatening injury that can occur following blunt or penetrating abdominal trauma. A 46-year-old male presented to the emergency department following a motor vehicle accident (MVA). He complained of severe abdominal pain and sustained ecchymosis with localized tenderness over the right upper quadrant. Despite a positive focused assessment with sonography in trauma scan, initial computed tomography of the abdomen revealed grade 1 liver and splenic injury but was unable to identify gallbladder perforation. He was initially managed conservatively until he developed secondary signs of sepsis after 24 hours. An exploratory laparotomy revealed a perforated gallbladder. A subtotal cholecystectomy was done. A retrospective review revealed a missed gallbladder perforation from an earlier CT scan assessment. We report a case of missed gallbladder perforation following MVA which was only diagnosed intraoperatively after failing non-operative management, following which the patient underwent laparotomy and subtotal cholecystectomy.

RESUMO

Delayed cerebral ischemia (DCI) remains a devastating complication in subarachnoid hemorrhage (SAH), however, there were no present reports that is associated with a ruptured spinal arteriovenous fistula (sAVF). We would like to present a rare case of DCI following embolization of a ruptured perimedullary sAVF. Initially, the patient clinical symptoms mimic a SAH caused by a ruptured intracranial aneurysm. Further evaluation revealed that the SAH was caused by a ruptured perimedullary sAVF and the patient’s condition improved following the embolization procedure. Three days later, the patient developed an acute left-sided facial and motor weakness, which persisted until the patient was discharged on the day-15 onset. A magnetic resonance imaging and angiography is performed 1.5 years after discharge and revealed no signs of cerebral infarction and hemorrhage. In this paper, we reported DCI after embolization in a ruptured sAVF with SAH, supported by evidence from the current literature. We would like to also stress the importance of complete spinal and cerebral vessel imaging to reveal the underlying abnormalities and determine the most appropriate intervention.

RESUMO

@#Introduction: Lean sustainability has gained prominence in the health sector for operational and business advantages. However, understanding the link between lean and healthcare sustainability, especially in social and environmental aspects, remains limited. This study introduces a preliminary framework for measuring lean healthcare sustainability in hospitals. The framework aligns Critical Success Factors (CSFs) with sustainability objectives and business strategies to ensure successful and enduring lean deployment. Methods: The study was conducted among 52 Lean Agile Hospitals in Malaysia using a cross-sectional approach. The validated questionnaire was employed for data collection. A reliability test and Exploratory Factor Analysis (EFA) were also performed to assess and validate the framework using Statistical Package for Social Sciences (SPSS) version 27. Results: The content validation was 0.9, which indicates that the instrument is sufficient to measure the research objective. The data screening test was performed to eliminate problem observation. The overall reliability value was over 0.830 which depicts data consistency and stability. The Kaiser-Meyer-Olkin exceeded 0.6, Bartlett’s test was under 0.001 and factor loading was between 0.507 to 0.948, thus indicating a significant correlation matrix among at least some of the variables. Therefore, the latent factors were significant to specific items of the research. Conclusion: It is concluded that important CSF is aligned with the strategic level influence of lean deployment in healthcare, which has a specific impact on certain sustainability performance. Thus, this paper proposed a generic preliminary framework to measure lean healthcare sustainability.

RESUMO

@#Introduction: Epithelial-mesenchymal transition (EMT) is a process of epithelial transformation into mesenchymal cells. It is also a process that contributes to the progression of fibrosis and cancer metastasis. Transforming growth factor-beta (TGF-β), as a potent inducer of EMT, has therefore became a potential therapeutic target. However, clinical developments of TGF-β inhibitors have been un-successful due to safety risks. Hence, drug repurposing of existing safe-to-use drugs could over-come this issue. Methods: In this study, the TGF-β receptor type 1 (ALK5) was selected as the target protein. Molecular docking was performed using known ALK5 inhibitors as positive controls. Clinical drugs with similar binding affinity and amino acid interaction were selected for in vitro experimental validation. Results: ALK5 inhibitor demonstrated binding affinities ranging from -11.2 to -9.5 kcal/mol. Analysis of amino acid interaction revealed that Val219, Ala230, Lys232, and Leu340 amino acid residues are crucial for binding. Subsequent screening of clinically approved drugs against ALK5 showed top five potential drugs (ergotamine, telmisartan, saquinavir, indinavir, and nelfinavir). The selected drugs were tested in TGF-β1-induced normal human bronchial epithelial cell line, BEAS-2B. Western blot analysis showed that the drugs did not exhibit inhibitory effects on the downregulation of epithelial proteins (E-cadherin) and upregulation of mesenchymal proteins (vimentin and α-smooth muscle actin). Conclusion: Based on these experimental outcome, it is postulated that the results from molecular docking were false positives. The tested drugs in this study could serve as negative controls in future screening against ALK5 protein.

RESUMO

@#Introduction: Atopic dermatitis (AD) is not only a cosmetic nuisance but is also associated with a significant impact on mental health and quality of life. Psychological symptoms are highly related to poor treatment adherence and recovery, more comorbidities, and a significant overall socioeconomic burden. Identifying the factors associated with anxiety and depression among patients with AD is important to modify and reduce the risk of developing these psychiatric complications. Methods: This was correlational research conducted in the dermatology clinic of four hospitals in Klang Valley, namely Hospital Kuala Lumpur, Hospital Tengku Ampuan Rahimah Klang, Hospital Selayang, and Hospital Ampang. By using a purposive sampling method, 128 samples (n=128) of adult patients with AD aged 18-65 were included. A questionnaire was administered regarding sociodemographic background, illness characteristics of AD, the Investigator’s Global Assessment (IGA), Malay version of the Automatic Thought Questionnaire-17, GAD-7, and PHQ-9. Results: The prevalence of anxiety and depressive symptoms among adult patients with AD is 31.3% and 46.9% respectively. Multivariable logistic regression analysis revealed that age and personal maladjustment (PM) predict anxiety symptoms, while only negative self-concept/expectation (NSNE) predicts depressive symptoms. The hierarchical logistic regression model explained 51% (Nagelkerke’s R2) of the variance in anxiety symptoms and 56% (Nagelkerke’s R2) of depressive symptoms. Conclusion: There is a high proportion of anxiety and depressive symptoms among adult patients with AD which is associated with negative automatic thoughts. In the management of adult patients with AD, clinicians should consider mental health symptom screening and monitoring.

RESUMO

@#The aim of this review was to provide an update on the current status of digital occlusal force measurement devices, as well as clinical and research applications in complete arch maximum occlusal force measurement. SCOPUS, ScienceDirect, and PubMed databases were used to conduct a literature search from January 2001 to January 2021. Identification and screening of literature were done independently according to published guidelines and selection criteria. The electronic searches turned up 394 articles, 16 of which met the inclusion and exclusion criteria and were selected for study analysis. All of these studies used T-scan and Dental Prescale digital occlusal analysis system with pressure-sensitive foils as occlusal force measurement devices. The devices showed a promising potential for identifying and comprehending maximum occlusal forces objectively. According to the current review, maximum occlusal force measured with digital occlusal force devices can be used as a prosthodontic adjunct to address issues that arise during the treatment of occlusal disorders, temporomandibular disorders, and complete dentures. It is also useful in predicting cognitive and functional decline in the elderly.

RESUMO

ABSTRACT Post-thoracotomy paraplegia after non-aortic surgery is an extremely uncommon complication. A 56-year-old woman presented with a 1-year history of progressive shortness of breath. Computed tomography revealed a locally advanced posterior mediastinal mass involving the ribs and the left neural foramina. Tumor excision with a left pneumonectomy was performed. Post-resection, bleeding was noted in the vicinity of the T4-T5 vertebral body, and the bleeding point was packed with oxidized cellulose gauze (Surgicel®). Postoperatively, the patient complained of bilateral leg numbness extending up to the T5 level, with bilateral paraplegia. An urgent laminectomy was performed, and we noted that the spinal cord was compressed by two masses of Surgicel® with blood clots measuring 1.5 × 1.5cm at T4 and T5 levels. The paraplegia did not improve despite the removal of the mass, sufficient decompression, and aggressive postoperative physiotherapy. Surgeons operating in fields close to the intervertebral foramen should be aware of the possible threat to the adjacent spinal canal as helpful hemostatic agents can become a preventable threat.

RESUMO

Background@#and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. @*Methods@#We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). @*Results@#There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. @*Conclusions@#During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.

RESUMO

ABSTRACT@#Granulomatosis with polyangiitis (GPA) is a rare multisystem disease. Although GPA is rare, it commonly presents in a localised stage where its manifestation involves the upper or lower respiratory tract before progressing to a generalised stage. Therefore, most patients with GPA will visit an oral surgeon or an otolaryngologist to seek treatment. However, the diagnosis of GPA is often delayed as GPA is not frequently considered as a differential diagnosis in common oral and facial diseases. The lack of gold standard investigation for the diagnosis of GPA makes management of this case, a diagnostic conundrum. We herein report a patient who was diagnosed with bilateral acute otitis media and left mastoiditis complicated with facial nerve palsy, and later developed tongue ulceration one month after his initial presentation. The ear, facial and oral symptoms represent a diagnostic red herring to a full-blown generalised stage of GPA.

RESUMO

@#Introduction: Acute transfusion reactions (ATR) are commonly reported in clinical transfusion practice, which may result in significant morbidity and mortality. This study aims to explore the impact of transfusion practice on the prevalence, characteristics, and associated factors of ATR at Hospital Sultanah Bahiyah, Kedah, Malaysia. Methods: This was a retrospective study using records from haemovigilance forms of reported transfusion reactions, E-Delphyn (blood bank system), and E-His (hospital information system). A total of 118 cases of ATR from January 1, 2015 until December 31, 2017 were selected and analysed. For each case, a control was selected from a patient who did not develop ATR. Results: A total of 122,215 units of whole blood and blood component transfusions have been performed and 415 ATR were reported. The prevalence of ATR was 0.34% or one in 294 units transfused. There was a significant association between ATR and red cell concentrate (RCC) stored for more than 14 days (adj OR = 65.29, 95% CI 9.29-458.85). The most common ATR were allergic reactions with 63 cases (53.4%), followed by febrile non-haemolytic transfusion reactions (FNHTR) with 45 cases (38.1%). Allergic reactions were significantly associated with female patients (p = 0.038) and the paediatrics age group (p = 0.038). Multivariate analysis revealed a significant association between FNHTR and RCC stored more than 14 days (p = 0.002). Conclusion: The prevalence of ATR in this hospital was low and associated with RCC stored for more than 14 days. Implementation of pre-storage leucoreduction is recommended.

RESUMO

The computer vision diagnostic approach currently generates several malaria diagnostic tools. It enhances the accessible and straightforward diagnostics that necessary for clinics and health centers in malaria-endemic areas. A new computer malaria diagnostics tool called the malaria scanner was used to investigate living malaria parasites with easy sample preparation, fast and user-friendly. The cultured Plasmodium parasites were used to confirm the sensitivity of this technique then compared to fluorescence-activated cell sorting (FACS) analysis and light microscopic examination. The measured percentage of parasitemia by the malaria scanner revealed higher precision than microscopy and was similar to FACS. The coefficients of variation of this technique were 1.2-6.7% for Plasmodium knowlesi and 0.3-4.8% for P. falciparum. It allowed determining parasitemia levels of 0.1% or higher, with coefficient of variation smaller than 10%. In terms of the precision range of parasitemia, both high and low ranges showed similar precision results. Pearson’s correlation test was used to evaluate the correlation data coming from all methods. A strong correlation of measured parasitemia (r2=0.99, P<0.05) was observed between each method. The parasitemia analysis using this new diagnostic tool needs technical improvement, particularly in the differentiation of malaria species.

RESUMO

ABSTRACT@#The study aimed to quantify the impact of lockdown during the COVID-19 pandemic on new case referrals to the Oral and Maxillofacial Surgery (OMS) service. The researchers retrospectively reviewed all new referrals received during a government-imposed 47-day lockdown period and a similar period pre-lockdown as a control group. The main outcome was the differences in the number of new case referrals between the two periods. The contributing clinical and demographic factors were also explored. Appropriate bivariate statistics were computed and the level of significance was set at 0.05 for all tests. A total of 309 referrals were received during the study period. There was a reduction of new referrals due to the lockdown from five to two cases per day. There was a statistically significant reduction of cases referred from outpatient and emergency departments. There was also a statistically significant difference with regard to home address distance to the centre. Medically compromised and orofacial infection referrals were not affected by lockdown. The lockdown imposed due to the pandemic has significantly impacted the pattern of new OMS referrals. Referrals for orofacial infections, the medically compromised and inpatients were minimally affected by lockdown.

RESUMO

@#Introduction: A compulsory research component is becoming increasingly common for clinical residents. However, integrating research into a busy clinical training schedule can be challenging. This study aimed to explore barriers to research supervision in specialist training programmes from the perspectives of clinical supervisors and trainees at a Malaysian university hospital. Methods: Qualitative interviews and focus group discussions were conducted (December 2016 to July 2017) with clinical supervisors (n=11) and clinical trainees (n=26) utilising a topic guide exploring institutional guidelines, research culture and supervisor-student roles. Interviews were transcribed verbatim and analysed thematically to identify barriers to research supervision. Results: Supervisors and trainees from 11 out of 18 departments participated. Both clinical supervisors and trainees struggled to successfully integrate a compulsory research component into residency training. Among the reasons identified included a lack of supervisory access due to the nature of clinical rotations and placements, clashing training priorities (clinical vs research) that discouraged trainees and supervisors from engaging in research, poor research expertise and experience among clinical supervisors hampering high-quality supervision, and a frustrating lack of clear standards between the various parties involved in research guidance and examination. Conclusion: Both clinical supervisors and trainees struggled to successfully integrate a compulsory research component into residency training. This was not only an issue of resource limitation since questions regarding clinical priorities and unclear research standards emerged. Thus, institutional coordinators need to set clear standards and provide adequate training to make research meaningful and achievable for busy clinical supervisors and trainees.

RESUMO

Background: PCOS has been recognized as the most frequent endocrinopathy among reproductive aged women. This study has been done to determine whether the measurement of serum AMH can be used to diagnose PCOS and as a tool to predict the prognosis of PCOS.Methods: This was a prospective case control study on a woman attending gynae OPD of LLRM Medical College, Meerut, from May 2018 to June 2019. Study comprised of 50 women diagnosed with PCOS using Rotterdam criteria and 50 controls. Clinical data were collected including history, oligomenorrhea, hirsutism, examination included BMI, FG score and blood investigations including serum FSH, LH, TSH, prolactin, estradiol and serum AMH level. USG was done for all women.Results: Both PCOS cases and controls were matched for age and BMI. Mean level of AMH in PCOS cases and controls was 7.1096 and 2.423 respectively, AMH was two to three times higher in women with PCOS than controls which was statistically significant (p<0.05). Most frequent phenotype of PCOS in this study was phenotype A (48%). Highest mean level of AMH was also found in phenotype A (OA+HA+PCOM), thus reflecting the severity of PCOS. Maximum diagnostic potential for PCOS was at cut off 4.22 ng/ml with sensitivity of 92.5% and specificity of 100%.Conclusions: AMH level can be used as diagnostic and prognostic modalities in PCOS. AMH value rises when hyperandrogenism is present therefore serum AMH levels also reflect the phenotype of PCOS and severity of PCOS.

RESUMO

Background: Echinococcosis is caused by parasite called Echinococcus granulosus and Echinococcus multilocularis. The modern treatment of hydatid cyst of the liver varies from surgical intervention to percutaneous drainage or medical therapy.Methods: This clinical study was done on 50 patients who had liver hydatid disease admitted in Sir T Hospital, Bhavnagar from August 2013 to February 2016. Patients were divided into two groups consisting of 25 cases in each. Group A: managed by open surgery. Group B: managed by laparoscopic surgery. All patients followed up for 6 months after surgery.Results: The mean operative time in Group A was 65.2 minutes (range 35-100 minutes) while in Group B it was 76.32 minutes (range 50-100 minutes). Group B patients were mobilised early and resumed duty very fast then Group A. The mean duration of stay in hospital was 12.4 days (range 4-20 days) in Group A and  6.2 days (range 4-12 days) in Group B. Wound infection seen in 16% in Group A and 0% in Group B. General complication rate was 32% in Group A and 8% in Group B. No recurrence noticed in either group during follow up.Conclusions: Overall laparoscopic management of liver hydatid cyst is cost effective in terms of early mobilization, early discharge and early resumption of work along with cosmetic benefit.

RESUMO

Two triterpenoid and alkaloid compounds have been isolated, namely, 3-acetyl-12-en-28-oic acid and (R)-N-transferuloyloctopamine from Melochia umbellata (Houtt.) Stapf var Visenia. Both of these compounds were tested asan antimicrobial and anti-HCV activity. Isolation has been done by maceration, fractionation, and purification. Themolecular structure was determined by IR spectroscopy and nuclear magnetic resonance (NMR) 1,2D (1H-NMR, 13C-NMR, HSQC, and HMBC). Antimicrobial assay of 3-acetyl-12-en-28-oic acid showed a zone of inhibition in thecriteria of moderate to active against Escherichia coli (8.4 mm), Salmonella thypi (11.2 mm), Staphylococcus aureus(10.8 mm), and Candida albicans (8.5 mm), as well as compounds (R)-N-trans-feruloyloctopamine that is againstE. coli (7.0 mm), S. thypi (10.55 mm), S. aureus (9.1 mm), and C. albicans (7.9 mm). Anti-HCV tests on the twocompounds showed IC50 values of 52.07 and 45.02 μg/ml, respectively. The results of these tests indicate that the twocompounds are potential as an antibiotic candidate.

RESUMO

Labia minora hypertrophy is a relatively uncommon surgical condition being popularised in the realm of vulvovaginal plastic surgeries. Apart from the unaesthetic appearance of the hypertrophied minora, these cases are also associated with itching, hygiene problem, pain while sitting down, sports activities, difficulty in wearing tight clothing, bleeding and discomfort while or after sexual intercourse, social embarrassment, insecurity and psychological diminution of confidence and self‐esteem. In a country like India, due to sociocultural reasons, patients hesitate to consult a doctor for such deformities. Most of the patients suffer in silence for years. Although common in the west, very few surgeons in the country perform this simple and rewarding surgery. Here, presenting a case of married women of reproductive age group presented to the study side with complains of severe vulvar itching, the cause of itching was labia minora hypertrophy.
