Clinico-dermoscopic and Histopathological Evaluation of Benign Skin, Soft Tissue and Appendageal Tumours of Skin: A Cross-sectional Study from a Tertiary Care Hospital

Abstract Background: Benign skin, soft tissue and appendageal tumours of skin are one of the most frequently encountered skin disorders. An organised systematic approach along with dermoscopic and histopathological examination can aid in the diagnosis of these diverse disorders. Objective: To evaluate clinico-dermoscopic and histopathological findings of benign skin, soft tissue and appendageal tumours of skin in patients attending a tertiary care hospital. Methods: Cross-sectional hospital-based study where patients of all age groups irrespective of gender suspected of having benign skin, soft tissue and appendageal tumours were enrolled. Clinical, dermoscopic and histopathological findings were recorded and the agreements between them were evaluated using the Cohenʼs Kappa coefficient. Results: The study included a total of 415 patients with a mean age of 37.9 ± 15.59 years and a male to female ratio of 1:1.3. The mean duration of the disease was 4.3 ± 2.14 years. Soft tissue tumours were the commonest (60%), followed by benign skin tumours (24.3%) and benign appendageal tumours (17.1%). A good agreement between dermoscopic and clinical diagnosis was found (Cohenʼs Kappa = 0.879) and between dermoscopic and histopathological diagnosis was also found (Cohenʼs Kappa = 0.789). Conclusion: This study infers that benign tumours of the skin include a heterogeneous group of skin disorders affecting a heterogeneous population. Dermoscopy improved the diagnostic accuracy of this large group of skin disorders and reduced the number of unnecessary excisions; however, histopathology remains the benchmark diagnostic tool to differentiate these tumours from other benign tumours and their malignant counterparts.

Evaluation of the minor clinical features of Hanifin and Rajka amongst children with atopic dermatitis, visiting a tertiary care hospital in North Eastern India

Atopic Dermatitis (AD) is a commonly encountered, extremely itchy, chronic and relapsing skin disorder, which is characterized by inflammation in the skin. It typically has its onset in childhood, presenting with eczematous lesions; and can also be associated with personal or family history of “atopy”, usually most often. The criterion put by Hanifin and Rajka, encompassing 4 major plus 23 minor criteria, is not infrequently used as a diagnostic criterion for this disease in a hospital setup; however, the frequency of occurrence of the minor criteria usually varies in the population.The study aims at estimating the frequency of the minor diagnostic criteria of the Hanifin and Rajka in children with AD. This was a hospital-based cross-sectional study, that was conducted on 70 children (less than 18yrs of age) by taking their history, doing clinical and ophthalmological examination and some basic tests.The most common occurrence amongst the minor criteria estimated from our study was xerosis i.e., in 45(64.2%). The other common minor criteria observed were pityriasis alba (42.8%) facial erythema (40%), orbital darkening (37.14%) Early age of onset was seen in children (35.7%). There is variation in the clinical features of AD according to geography and population. The prevalence and severity of the disease are dependent on several factors like ethnicity/race and environment. Hence, it is important for dermatologists to know the usual and common ways the disease presents, in a given population for the diagnosis so as to diagnose and treat the patients at an earlier stage and before significant discomfort.

The digital health landscape at children’s hospitals in Canada

ABSTRACT Objectives Canadian hospitals have historically lagged behind peer nations in terms of adoption of digital health tools. The aim of this study was to assess the current state of adoption of digital health tools at children’s hospitals in Canada. Methods We conducted an online survey of Canadian pediatric tertiary-care hospitals between January and July 2023. The 35-item questionnaire was administered in English and French. Hospital characteristics, informatics infrastructure data and electronic health record (EHR) functionality data were summarized using descriptive statistics. Results The survey was completed by 15 of the 17 (88.2%) pediatric hospitals in Canada. All institutions had an EHR with 10 (66.6%) being fully digitized and five (33.3%) being partially digitized. Funding and availability of clinicians with expertise in clinical informatics were cited as barriers to implementing digital health tools. The availability of core EHR functionalities ranged from 53.3% for medication to 100% for the presence of a laboratory and radiology information system. Only five (33.3%) institutions reported that they had a patient portal. Discussion While all hospitals in this study had an EHR, functionalities varied greatly between centers. Canada lags behind the United States in terms of adoption of digital health tools such as patient portals likely due to governmental mandates and incentives, and a focus on cultivating a physician informatics workforce. Conclusion Canadian pediatric hospitals lag behind peer institutions in digital maturity. This study highlights the perceived need from hospitals for policies, funding, and resources from the Canadian government to help increase the uptake of comprehensive EHRs.

A longitudinal point prevalence survey of antimicrobial use and resistance in tertiary care hospitals in Kerman: results from the national Iranian multicenter point prevalence survey of antimicrobials in 2021.

The Global Point Prevalence Survey (PPS) of antimicrobial consumption and resistance has been widely undertaken to combat the global threat of antimicrobial resistance (AMR). This study was conducted in alignment with the Global-PPS in three tertiary care hospitals in Kerman, Iran, to evaluate antimicrobial consumption patterns. The study was conducted from January 2020 to January 2021 in Afzalipour, Shafa, and Shahid Bahonar Hospitals. Data were collected using the standardized Global-PPS method at three different points throughout the year to minimize bias. Information on antimicrobial prescriptions, primary diagnosis, prophylaxis, therapy indications, and treatment type were documented. Antimicrobial prevalence was calculated using the total number of admitted patients as the denominator and those on antimicrobial regimens as the numerator. The point prevalence of antimicrobial consumption in adult wards was 65.6% in Afzalipour Hospital, 42.3% in Shafa Hospital, and 78.7% in Bahonar Hospital. Non-penicillin beta-lactams, macrolides, lincosamides, and streptogramins were the most frequently prescribed antibiotic classes. Approximately 80% of prescriptions had explicit reasons documented, and targeted antibiotic therapy rates varied between 7.7% and 44.8% across hospitals. Antimicrobial consumption in Kerman's tertiary care hospitals exceeded national and global levels, indicating an urgent need for interventions to promote rational antibiotic use. Infection control committees must implement rigorous monitoring measures to reduce antimicrobial resistance. Ongoing surveillance and targeted interventions are essential to curb the rising rates of antimicrobial resistance in the region.

Tenofovir and Hepatitis B Virus Transmission During Pregnancy: A Randomized Clinical Trial.

Standard care for preventing mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in highly viremic mothers consists of maternal antiviral prophylaxis beginning at gestational week 28 combined with an HBV vaccine series and HBV immune globulin (HBIG) at birth. However, HBIG is unavailable in some resource-limited areas. To determine whether initiating tenofovir disoproxil fumarate (TDF) at gestational week 16 combined with HBV vaccinations for infants is noninferior to the standard care of TDF at gestational week 28 combined with HBV vaccinations and HBIG for infants in preventing MTCT in mothers with HBV and high levels of viremia. An unblinded, 2-group, randomized, noninferiority clinical trial was conducted in 7 tertiary care hospitals in China. A total of 280 pregnant individuals (who all identified as women) with HBV DNA levels greater than 200 000 IU/mL were enrolled between June 4, 2018, and February 8, 2021. The final follow-up occurred on March 1, 2022. Pregnant individuals were randomly assigned to receive either TDF starting at gestational week 16 with HBV vaccinations for the infant or TDF starting at gestational week 28 with HBV vaccinations and HBIG administered to the infant. The primary outcome was the MTCT rate, defined as detectable HBV DNA greater than 20 IU/mL or hepatitis B surface antigen positivity in infants at age 28 weeks. Noninferiority was established if the MTCT rate in the experimental group did not increase by more than an absolute difference of 3% compared with the standard care group, as measured by the upper limit of the 2-sided 90% CI. Among 280 pregnant individuals who enrolled in the trial (mean age, 28 years; mean gestational age at enrollment, 16 weeks), 265 (95%) completed the study. Among all live-born infants, using the last observation carried forward, the MTCT rate was 0.76% (1/131) in the experimental group and 0% (0/142) in the standard care group. In the per-protocol analysis, the MTCT rate was 0% (0/124) in the experimental group and 0% (0/141) in the standard care group. The between-group difference was 0.76% (upper limit of the 2-sided 90% CI, 1.74%) in all live-born infants and 0% (upper limit of the 2-sided 90% CI, 1.43%) in the per-protocol analysis. Both comparisons met the criterion for noninferiority. Rates of congenital defects and malformations were 2.3% (3/131) in the experimental group and 6.3% (9/142) in the standard care group (difference, 4% [2-sided 95% CI, -8.8% to 0.7%]). Among pregnant women with HBV and high levels of viremia, TDF beginning at gestational week 16 combined with HBV vaccination for infants was noninferior to the standard care of TDF beginning at gestational week 28 combined with HBIG and HBV vaccination for infants. These results support beginning TDF at gestational week 16 combined with infant HBV vaccine to prevent MTCT of HBV in geographic areas where HBIG is not available. ClinicalTrials.gov Identifier: NCT03476083.

The efficacy of P0.1-guided sedation protocol in critically ill patients receiving invasive mechanical ventilation: A randomized controlled trial

Background: Mechanical ventilation is a lifesaving treatment in patients with acute respiratory failure. Despite optimal support, some patients still exhibit excessive respiratory drive, leading to patient self-inflicted lung injury (P-SILI) and diaphragmatic dysfunction. Sedation and muscle relaxants are commonly used to reduce respiratory efforts and manage patient-ventilator asynchrony (PVA). Conventionally, sedative drugs are adjusted based on the sedation level assessed by the Richmond Agitation-Sedation Scale (RASS), which may not correlate with the patient’s respiratory drive. Drop in airway pressure at the first 100 milliseconds of the beginning of the inspiration after the end-expiratory occlusion (P0.1) is a simple and reliable method of respiratory drive monitoring by mechanical ventilation at the bedside and may be the more suitable sedation target. Objectives: To assess the efficacy of a sedation protocol targeting optimal P0.1 and RASS score compared to conventional sedation strategy in patients requiring invasive mechanical ventilation in the medical intensive care units in terms of successful extubation. Methods: This is an open-labeled, single-center, randomized controlled trial conducted in medical intensive care units at a tertiary care hospital in Bangkok, Thailand. We randomly allocated mechanically ventilated patients in a 1:1 ratio to receive a sedation protocol targeting both optimal respiratory drive measured by P0.1 (intervention group) and light sedation (RASS 0 to -2) or standard of care (control group targeting RASS alone). The primary outcome is the rate of successful extubation within 14 days after randomization. Hypothesis: We hypothesize that sedation protocol targeting optimal P0.1 and light sedation will increase the rate of successful extubation at 14 days in mechanically ventilated patients compared to conventional sedation strategy. Conclusions: This study aims to evaluate the efficacy of a sedation protocol using P0.1 measurement to monitor and target optimal respiratory drive, in conjunction with sedation scores, in critically ill patients receiving invasive mechanical ventilation. Ethics and dissemination: This study protocol was approved by the Human Research Protection Unit of the Faculty of Medicine, Siriraj Hospital, Mahidol University (Certificate of Approval no. Si 915/2023). Trial registration: NCT06203405

AdeABC, AdeFGH, and AdeIJK efflux pumps as key factors in tigecycline resistance of Acinetobacter baumannii: a study from Western Balkan hospitals.

The present study investigated the role of resistance-nodulation-cell division (RND) efflux pumps in tigecycline resistance of Acinetobacter baumannii clinical isolates recovered from three Western Balkan countries (Serbia, Bosnia and Herzegovina and Montenegro). A total of 37 A. baumannii isolates recovered from seven tertiary care hospitals in 2016 and 2022 were tested against tigecycline using broth microdilution method. Then, efflux pump inhibitor carbonyl cyanide 3-chlorophenylhydrazone (CCCP) was used to determine the involvement of efflux pumps in tigecycline resistance. Molecular typing was performed by pulsed-field gel electrophoresis (PFGE) and multiplex PCR-based determination of clonal lineage. Regulators of efflux pumps were analyzed for amino acid substitutions, while reverse transcription-quantitative PCR (RT-qPCR) enabled quantification of RND efflux pumps expression. All tested isolates were interpreted as resistant to tigecycline and showed reduced tigecycline minimum inhibitory concentration (MIC) values in the presence of CCCP. PFGE analysis showed significant diversity among isolates grouped in cluster I including IC2 (n = 32) and IC3 (n = 1) isolates, while cluster II was comprised of four IC1 isolates. The most prevalent substitutions in AdeR were V120I and A136V and in AdeS G186V and N268H (n = 33). The Q262R substitution was detected in AdeL proteins of IC1 isolates, whereas no alterations were observed within AdeN. The expression of the adeB, adeG, and adeJ genes in selected isolates was upregulated in five (1.16- to 3-fold), sixteen (1.35- to 2.82-fold), and twelve isolates (1.62- to 4-fold) compared to ATCC19606, respectively. This study revealed that overexpression of RND efflux pumps underlies tigecycline resistance in A. baumannii clinical isolates from the Western Balkans.

Pattern of Rapidly growing Mycobacteria (RGM) species isolated from clinical samples: A 10-year retrospective study in a tertiary care hospital of Bangladesh.

Infections caused by rapidly growing mycobacteria (RGM) are increasing worldwide. The study was conducted in a microbiological laboratory of Bangladesh to determine the pattern of detection of RGM from clinical samples. All laboratory culture records of RGM from 2012 to 2022 were collected retrospectively and analyzed. A total 62 RGM infected patients with surgical site infection (74.1%), injection site and skin abscess (9.7%), septicemia (4.8%) and UTI (1.6%) were identified. The annual isolation frequency of RGM increased 4.8% to 29.1% in between year 2012 and 2022. RGM infected patients (14.5%) were mistakenly treated with first line anti tubercular drug before correct microbiological diagnosis (median, IQR; 3, 2-5 months). Out of 23 RGM isolates, 86.9% were M. abscessus and rest 13.1% were M. fortuitum. Most of them (≥95%) were sensitive to amikacin, linezolid, clarithromycin where as 27.1% to imipenem and ciprofloxacin, 40% to cefoxitin, 35.3% and 1.7% to doxycycline and co-trimoxazole respectively. Misdiagnosis or delay in diagnosis and erroneous treatment with first line anti tubercular drug may cause prolong morbidity and therapeutic failure to patients with RGM infection. So, early and appropriate diagnosis is crucial for successful outcome.

Impact of Interhospital Transfer on Outcomes in Acute Pancreatitis: Implications for Healthcare Quality

Background/Objectives: Effective management of acute pancreatitis (AP) hinges on prompt volume resuscitation and is adversely affected by delays in diagnosis. Given diverse clinical settings (tertiary care vs. community hospitals), further investigation is needed to understand the impact of the initial setting to which patients presented on clinical outcomes and quality of care. This study aimed to compare outcomes and quality indicators between AP patients who first presented to the emergency department (ED) of a tertiary care center and AP patients transferred from community hospitals. Methods: This study included AP patients managed at our tertiary care hospital between 2008 and 2018. We compared demographics and outcomes, including length of stay (LOS), intensive care unit (ICU) admission, rates of local and systemic complications, re-admission rates, and one-year mortality in transferred patients and those admitted from the ED. Quality indicators of interest included duration of volume resuscitation, time until advancement to enteral feeding, pain requiring opioid medication [measured in morphine milliequivalent (MME) dosing], and surgical referrals for cholecystectomy. Categorical variables were analyzed by chi-square or Fisher’s exact test; continuous variables were compared using Kruskal–Wallis tests. Regression was performed to assess the impact of transfer status on our outcomes of interest. Results: Our cohort of 882 AP patients comprised 648 patients admitted from the ED and 234 patients transferred from a community hospital. Transferred patients were older (54.6 vs. 51.0 years old, p < 0.01) and had less frequent alcohol use (28% vs. 39%, p < 0.01). Transferred patients had a significantly greater frequency of gallstone AP (40% vs. 23%), but a lower frequency of alcohol AP (16% vs. 22%) and idiopathic AP (29% vs. 41%) (p < 0.001). Regarding clinical outcomes, transferred patients had significantly higher rates of severe AP (revised Atlanta classification) (10% vs. 2% severe, p < 0.001) and ICU admission (8% vs. 2%, p < 0.001) and longer median LOS (5 vs. 4 days, p < 0.001). Regarding quality indicators, there was no significant difference in the number of days of intravenous fluid administration, or days until advancement to enteral feeding, pain requiring opioid pain medication, or rates of surgical referral for cholecystectomy. Conclusions: Though the quality of care was similar in both groups, transferred patients had more severe AP with higher rates of systemic complications and ICU admissions and longer LOS, with no difference in quality indicators between groups.

EGS SO33 - Management Strategies and Outcomes of Non-Malignant Oesophageal Perforation at a Tertiary Care Hospital

Abstract Background Oesophageal perforation is a life-threatening emergency that requires prompt and effective management. This study aims to evaluate the outcomes of different management strategies—conservative, surgical, and endoscopic washout with stent insertion—for non-malignant oesophageal perforations at a specialist Upper GI unit in a tertiary care hospital. Method This is a retrospective study conducted over a 10-year period from 2012 at a specialist Upper GI Unit in a tertiary care hospital. All patients aged 18 and above who were referred to or admitted with oesophageal perforation were included, with exclusion of those with underlying oesophageal cancer. Data were collected from hospital records. Variables studied included age, gender, Charlson Comorbidity Index (CCI), WHO performance status, site and size of oesophageal perforation, treatment modality (Conservative, Surgery, or Stent), type and size of stent used, length of hospital stay, and mortality. Data analysis was performed using SPSS v.25. Results Over 10 years, 72 cases of non-malignant oesophageal perforation were managed (M:F, 37:35, median age 62.5 years (range 20-86), median CCI 3). The causes of perforation were spontaneous (n=45, 62.5%), iatrogenic (n=22,30.6%), foreign body (n=4,5.6%), and post-corrosive intake (n=1,1.4%). Most perforations occurred in the distal oesophagus (n=52, 72.2%) with an average size of perforation of 3 ± 1.38cm. Management included surgery (n=43,59.7%), conservative treatment (n=22,30.6%), and stent insertion (n=7,9.7%). Overall, in-hospital mortality was 20.8% (n=15). Survival rates varied: 90.9% for conservative treatment, 79.1% for surgical management, and 57.1% for stenting; however, the differences were not statistically significant (p=0.134). Conclusion Oesophageal perforation is a life-threatening condition. This 10-year observational study assessing conservative, surgical, and stent treatments for non-malignant perforations confirms that survival rates varied among the different treatment groups. However, there was no statistically significant survival advantage observed. This underscores the importance of developing individualized management plans based on patient factors to improve outcomes.

BN SO06 - Comparison of local infiltration of tramadol versus bupivacaine for Post-operative pain relief

Abstract Background To compare the mean pain score of local infiltration of tramadol and bupivacaine among patients undergoing hernioplasty, a Tertiary Care Hospital, Karachi. Method Quantitative and qualitative data was collected, presented and analyzed. Effect modifiers were controlled through stratification to see the effect of these on the outcome variable. Post stratification independent t test was applied taking p-value of ≤0.05 as significant. Results Mean postoperative pain at 24 hours in tramadol versus bupivacaine group was 1.65±0.58 and 1.72±0.82 respectively. P-value was 0.001. Conclusion Locally infiltrated tramadol prior to herniorrhaphy wound closure provides better pain relief compared to bupivacaine in adult patients

Exploring the Link between Periodontal Disease and Systemic Conditions: Implications for Alzheimer’s, Parkinson’s, and Rheumatoid Arthritis

ABSTRACT Background: There is a growing correlation between periodontal disease, a common inflammatory disorder that affects the tissues supporting the teeth, and several systemic diseases. Materials and Methods: Two hundred patients from a tertiary care hospital, ages 50–75, participated in this cross-sectional research. The subjects were split up into four groups: 50 individuals with rheumatoid arthritis, 50 with Alzheimer’s disease, 50 with Parkinson’s disease, and 50 with periodontal disease. To evaluate periodontal condition, including clinical attachment loss and pocket depth, thorough oral exams were performed. Measurements were made of serum biomarkers for inflammation, such as interleukin-6 (IL-6) and C-reactive protein (CRP). Multivariate regression models were used to examine correlations between the severity of periodontal disease and the underlying systemic diseases. Results: In all groups, there were significant relationships between higher levels of indicators of systemic inflammation and the severity of periodontal disease. In comparison to healthy controls (CRP mean value: 2.1 mg/L; IL-6 mean value: 6.4 pg/mL), participants with periodontal disease had higher mean levels of CRP (5.6 mg/L) and IL-6 (mean value: 12.8 pg/mL). Furthermore, compared to those with rheumatoid arthritis, those with Alzheimer’s and Parkinson’s disorders showed higher levels of pocket depth and periodontal attachment loss. Conclusion: In conclusion, the results point to a possible connection between systemic diseases such rheumatoid arthritis, Parkinson’s disease, and Alzheimer’s.

Anesthesia in Obese Patients and Complications

Background: Almost all ages and socioeconomic categories are affected by the complex illness known as obesity, which has major social and psychological ramifications. Global obesity rates have reached epidemic proportions and obesity plays a significant role in the burden of chronic illnesses and disabilities worldwide. The aim of the study was to assess the Anesthesia in obese patient and its Complications in a tertiary care hospital. Materials and mathods: This cross-sectional observational study was carried out in the Department of Anesthesiology, Bangabandhu Memorial Hospital (BBMH) from July 2020 to June 2022.Total sample size was 200. Adult in-patients who had undergone non-cardiac surgery and were older than 18 with a BMI greater than 30 kg/m2 met the inclusion criteria. Pregnancy, ambulatory surgery and missing or insufficient data on the desired outcomes were the exclusion criteria. Results: Mean age ±SD was 32 ± 0.9 years. About 55% of the patients were female and 45% were male. Regarding ASA classification 53.5% had 2, 45.5% had 3 and 1.0% had 4 score. Regarding coexisting disease 42.5% had hypertension, 14% had dyslipidemia, 18% had DM type-2 and 7.5% had obstructive sleep apnea. Here, type of anesthesia was 55% general anesthesia, 6% normal mask ventilation, 25% regional anesthesia, 4% total intravenous anesthesia and 10% LMA (Laryngeal Mask Airway). Regarding complication 4.5% was Reintubation, 5.5 %Pneumonia, 7.5% Upper airway obstruction, 0.5% Delay emergence respectively. 2.5% Urinary retention, 5% Oliguria, 2% Wound infection. 0.5% myocardial infarction and 0.5% Cardiac arrest occurred and no death occur inpatient respectively. Conclusion: Obesity has long been seen from a surgical standpoint as a risk factor for unfavorable post-surgical outcomes. Patients who are morbidly obese may experience respiratory adverse effects following surgery as a result of physiological disruption. The undesirable effects range depending on the surgical population. IAHS Medical Journal Vol 7(1), June 2024; 97-101

Vitiligo Cases in the Out-Patient Department in a Tertiary Care Hospital

Background: The prevalence of vitiligo has been reported to range from 0.1% to 8% worldwide. It has a low mortality rate but a high morbidity cost because of its psychological and social effects. Type-1 diabetes mellitus, autoimmune thyroid disease and other autoimmune illnesses have been linked to this condition. This study was performed to assess the occurence of vitiligo among males and females and the epidemiological status of vitiligo in a tertiary Hospital of Dhaka, Bangladesh. Materials and methods: A cross-sectional survey was conducted among 3,212 adults (1,429 males and 1,783 females) in a community of Dhaka between October 2022 and May 2023 at OPD of Delta Medical College. Face-to face interviews were conducted at the OPD of Delta Medical College for each participant and all respondents had their skin examined by dermatologists. The risks of comorbidities associated with vitiligo were evaluated. Results: In this particular research project, most vitiligo patients were between the ages of 13 and 60 years. According to this research, the average age of vitiligo patients was 35.5 years. Here, the proportion rate for this is 2.74%. The ratio of male participants to female participants in this research was M:F = 1:1.51. Only 88 out of the 24 cases were stable, whereas around 64 were unstable. The focused kind of vitiligo was shown to be the most prevalent form of the condition in this particular research. Conclusion: Vitiligo was most common among individuals in Dhaka in their middle 30s and the incidence of the condition rise with age. In adult patients, vitiligo was connected with higher risks of alopecia areata, hypothyroidism, diabetes mellitus and atopic dermatitis. IAHS Medical Journal Vol 7(1), June 2024; 17-21

EGS SO27 - Removable covered stent as an alternative to traditional methods in management of Oesophageal Perforation in unfit surgical patients: A Tertiary Care Hospital Experience

Abstract Background Oesophageal perforation in elderly and frail patients carries a significantly higher mortality rate. Traditionally, management involves surgery for patients who are fit for surgery, or a conservative approach for those with minimal contamination. Endoscopy, with procedures such as endoscopic washout of mediastinal collections and placement of covered removable stents, sometimes in conjunction with chest drain insertion, is emerging as a minimally invasive option for a selected group of patients who are not suitable for traditional methods. This technique aims to seal perforations, promote healing, and facilitate early restoration of oral intake. Method This retrospective study was conducted at a tertiary care hospital. Data were collected over a 10-year period starting from 2012. The study enrolled all patients aged 18 and older, admitted with oesophageal perforation and underwent oesophageal stent insertion. SX-ELLA Danis-seal stents (30-25-30 × 135mm) were used for benign perforations, while permanent covered metal stents were used for patients with underlying malignancy. Variables analyzed included age, gender, Charlson Comorbidity Index (CCI), WHO performance status, location and size of esophageal perforation, type and dimensions of stent used, length of hospital stay, and mortality rates. Data analysis was conducted using SPSS version 25. Results During study period, 11 out of 78 patients with esophageal perforation underwent stent insertion (M:F=7:4, median age-71 (range 48-85) years, median CCI -5). Causes included spontaneous perforation (n=3,27.3%), iatrogenic (n=4,36.4%), and malignancy (n=4,36.4%). Distal esophageal perforation was observed in 7 patients (63.6%). Oral intake was commenced within 72 hours post-insertion. A single procedure sufficed for 10(90%) patients. Stents used for non-malignant perforations were removed endoscopically after an average of 12 weeks. No major complications; minor complications included stent migration (n=1, 9.1%), failed placement (n=1, 9.1%), and loss to follow-up (n=1, 9.1%). The 90-day mortality rate was 45.5% (n=5/11). Conclusion Endoscopy with mediastinal cavity washout and insertion of a covered metal stent in unfit surgical patients provides an alternative and improves outcomes. It could also be considered in patients with non-healing perforations to facilitate early resumption of oral intake.

In-hospital outcomes of healthcare-associated COVID-19 (Omicron) versus healthcare-associated influenza: a retrospective, nationwide cohort study in Switzerland.

As COVID-19 is integrated into existing infectious disease control programs, it is important to understand the comparative clinical impact of COVID-19 and other respiratory diseases. We conducted a retrospective cohort study of patients with symptomatic healthcare-associated COVID-19 or influenza reported to the nationwide, hospital-based surveillance system in Switzerland. Included patients were adults (≥18 years) hospitalized for ≥3 days in tertiary care and large regional hospitals. Patients had COVID-19 symptoms and a RT-PCR-confirmed SARS-CoV-2 infection ≥3 days after hospital admission between 1 February 2022 and 30 April 2023, or influenza symptoms and a RT-PCR-confirmed influenza A or B infection ≥3 days after hospital admission between 1 November 2018 and 30 April 2023. Primary and secondary outcomes were 30-day in-hospital mortality and admission to intensive care unit (ICU), respectively. Cox regression (Fine-Gray model) was used to account for time-dependency and competing events, with inverse probability weighting to adjust for confounding. We included 2901 patients with symptomatic healthcare-associated COVID-19 (Omicron) and 868 patients with symptomatic healthcare-associated influenza from nine hospitals. We found a similar case fatality ratio between healthcare-associated COVID-19 (Omicron) (6.2%) and healthcare-associated influenza (6.1%) patients; after adjustment, patients had a comparable subdistribution hazard ratio for 30-day in-hospital mortality (0.91, 95%CI 0.67-1.24). A similar proportion of patients were admitted to ICU (2.4% COVID-19; 2.6% influenza). COVID-19 and influenza continue to cause severe disease among hospitalized patients. Our results suggest that in-hospital mortality risk of healthcare-associated COVID-19 (Omicron) and healthcare-associated influenza are comparable.

QTc interval prolongation impact on in-hospital mortality in acute coronary syndromes patients using artificial intelligence and machine learning.

Prediction of mortality in hospitalized patients is a crucial and important problem. Several severity scoring systems over the past few decades and machine learning models for mortality prediction have been developed to predict in-hospital mortality. Our aim in this study was to apply machine learning (ML) algorithms using QTc interval to predict in-hospital mortality in ACS patients and compare them to the validated conventional risk scores. This study was retrospective, using supervised learning, and data mining. Out of a cohort of 500 patients admitted to a tertiary care hospital from September 2018 to August 2020, who presented with ACS. Prediction models for in-hospital mortality in ACS patients were developed using 3 ML algorithms. We employed the ensemble learning random forest (RF) model, the Naive Bayes (NB) model and the rule-based projective adaptive resonance theory (PART) model. These models were compared to one another and to two conventional validated risk scores; the Global Registry of Acute Coronary Events (GRACE) risk score and Thrombolysis in Myocardial Infarction (TIMI) risk score. Out of the 500 patients included in our study, 164 (32.8%) patients presented with unstable angina, 148 (29.6%) patients with non-ST-elevation myocardial infarction (NSTEMI) and 188 (37.6%) patients were having ST-elevation myocardial infarction (STEMI). 64 (12.8%) patients died in-hospital and the rest survived. Performance of prediction models was measured in an area under the receiver operating characteristic curve (AUC) ranged from 0.83 to 0.93 using all available variables compared to the GRACE score (0.9 SD 0.05) and the TIMI score (0.75 SD 0.02). Using QTc as a stand-alone variable yielded (0.67 SD 0.02) with a cutoff value 450 using Bazett's formula, whereas using QTc in addition to other variables of personal and clinical data and other ECG variables, the result was 0.8 SD 0.04. Results of RF and NB models were almost the same, but PART model yielded the least results. There was no significant difference of AUC values after replacing the missing values and applying class balancer. The proposed method can effectively predict patients at high risk of in-hospital mortality early in the setting of ACS using only clinical and ECG data. Prolonged QTc interval can be used as a risk predictor of in-hospital mortality in ACS patients.

Disease Pattern and Clinical Profile of Admitted Patients in Pediatric Intensive Care Unit of a Tertiary Care Hospital in Chattogram

Background: The care of critically ill children remains one of the most demanding and challenging aspects in the field of pediatrics. Pediatric Intensive Care Unit (PICU) aims at promoting early intervention and quality care for achieving good results and better prognosis. With the advancement in intensive care facilities, there is a dramatic increase in survival of critically ill children. It is usually offered to patients whose condition is potentially reversible and who have a good chance of surviving with intensive care support. Since these patients are critically ill, the outcome of intervention is sometimes difficult to predict. This study is aimed to assess the clinical profile of critically ill children presenting to the pediatric emergency room and then their admission pattern to the pediatric intensive care unit. This may help to assist intensivist and planners to pay due attention for better utilization of healthcare facilities. Better understanding leads to better management. Materials and methods: This is a cross-sectional study, conducted at the Pediatric Intensive Care Unit of Chattagram Maa Shishu-O-General Hospital from January to June of 2019. A total of 100 admitted cases were recruited and their symptoms and signs, clinical findings and diagnosis were recorded accordingly. All the patients were aged within 28 days to below 14 years. Results: Among the 100 study subjects, 66 were male and 34 were female. The mean age was 1.73 ± 2.6 years. Most children were admitted with respiratory distress though there were other accompanying signs and symptoms. The symptoms subjects commonly presented with were respiratory distress(76%), tachycardia(70%), lung crepitations (69%), tachypnea (68%), fever (67%), lethargy (59%), feeding difficulty (59%), convulsions (48%), low blood pressure (24%), hepatomegaly (19%), cyanosis (14%), edema (6%), congenital anomalies (4%). The clinical findings that led them to PICU admissions were bronchiolitis (4%), bronchopneumonia (42%), respiratory failure of any cause (4%), heart failure (7%), cyanotic congenital heart disease (8%), acyanoticcongenital heart disease (7%), meningitis (13%), encephalitis (12%), cerebral palsy with seizure disorder (21%), status epilepticus (2%), Gullein Barre Syndrome (3%), hyponatremic dehydration (6%), acute kidney injury (2%), acute leukemia (2%).In this study, neurological disorders such as cerebral palsy with seizure disorder and encephalitis and meningitis were among the top five in the diagnosis list. Septicemia with shock was also a very common finding promoting admission to PICU. GCS was found to be significantly lower in the above-mentioned disease conditions making admission to the ICU quite plausible. Conclusion: Children admitted to PICU may have multiple clinical findings and disease patterns. However, some diseases predominate the patient population admitted to PICU.The knowledge of clinical spectrum and epidemiological profile of critically ill children plays a significant role in the planning of health policies that would mitigate various factors related to the evolution of diseases prevalent in these sectors. Descriptive epidemiology focuses on identifying and reporting the pattern and frequency of events related to the health of a population. IAHS Medical Journal Vol 7(1), June 2024; 44-49

EGFR Evalutation among the Hypothyroid Patients Attending at a Tertiary Center of Chattogram

Background: Hypothyroidism is a prevalent endocrine illness that affects people all over the world. The modulation of renal hemodynamics and basal metabolic rate is disrupted in hypothyroidism. The kidney is generally involved in thyroid hormone metabolism, breakdown and excretion. Chronic renal hypoperfusion affects the hypothalamic pituitary-thyroid axis, resulting in low circulating thyroid hormone levels, changed peripheral hormone metabolism, decreased tissue thyroid hormone content and altered thyroid iodine storage. Recent research has linked an increased risk of hypothyroidism to a decreased estimated Glomerular Filtration Rate (eGFR). The purpose of the study is to determine the association between eGFR with hypothyroidism in a tertiary care hospital of Chattogram. Materials and methods: A cross-sectional study was done during July 2022 to June 2023 including 100 diagnosed hypothyroidism cases attending in Chittagong Medical College Hospital. Serum Thyroid Stimulating Hormone (TSH) serum free thyroxine (FT4) serum creatinine, and blood urea were measured. The estimated glomerular filtration rate (eGFR) were determined. The result were analysed using SPSS version 25. Results: The mean age was 42.76±10.18 years with 93% female. Most of the patients (92%) were in a subclinical hypothyroid state and 8% were in an overt hypothyroid state. The mean ±SD serum creatinine levels and urea levels were 0.8±0.2mg/dl and 25.4±6.5 mg/dl, respectively. The mean eGFR was 75.36±7.54 ml/min/1.73 m2. There was a significant decrease in mean eGFR in the < 60 ml/min/1.73m2 group among the study population. There was a significant association between decreased eGFR and hypothyroidism. Serum TSH had significantly shown a negative correlation with eGFR. Serum TSH level had a significant positive correlation with serum creatinine (r=0.56, p<0.05) and serum urea (r=0.25, p<0.05). There was a significant eGFR difference between subclinical hypothyroidism and overt hypothyroidism. Conclusion: It can be concluded from this study that the hypothyroidism was significantly correlated with decreased eGFR. IAHS Medical Journal Vol 7(1), June 2024; 86-90
