The Utility of the Platelet-Albumin-Bilirubin Score as a Non-invasive Predictor of Esophageal Varices and Variceal Hemorrhage in Patients With Liver Cirrhosis Compared to Child-Turcotte-Pugh and Model of End-Stage Liver Disease-Sodium Scores.

Introduction Research on non-invasive tools for detecting gastro-esophageal varices is underway. We investigated the Platelet-Albumin-Bilirubin (PALBI) score in comparison with the Child-Turcotte-Pugh (CTP) and MELD-Na (MELD-Na) scores in patients with liver cirrhosis. Methods Three hundred and twenty-three patients with liver cirrhosis were studied. The PALBI, CTP and MELD-Na scores were calculated and analyzed for gastroesophageal varices and their characteristics using SPSS version 26 (IBM Corp., Armonk, NY, USA). Results Two hundred and sixty-four patients had esophageal varices and 102 presented with variceal hemorrhage. Mean PALBI, CTP and MELD-Na scores were significantly higher for patients with varices versus without varices (p < 0.05). Unlike the mean MELD-Na score, the mean PALBI and CTP scores were significantly higher in patients with large high-risk varices as compared to patients with small low-risk varices (p < 0.05). The mean CTP scores were significantly higher in patients with variceal hemorrhage than those without hemorrhage (p < 0.05), while the difference between mean PALBI and MELD-Na was insignificant, in this regard. The PALBI score had better sensitivity than the CTP and MELD-Na scores in indicating the presence of varices but was similar to the CTP score in predicting high-risk varices. Conclusion The PALBI score proves to have good utility and efficiency in predicting varices in comparison to CTP and MELD-Na scores. It can determine high-risk stigmata of variceal hemorrhage with similar performance as the CTP Score.

The Association of Helicobacter pylori With Portal Hypertensive Gastropathy in Patients With and Without Cirrhosis.

INTRODUCTION: Cirrhosis and its associated complication of portal hypertensive gastropathy (PHG), among others, remain a significant cause of death in resource-poor countries with limited capacity for liver transplantation. This research aimed to assess the association of Helicobacter pylori (H. pylori) with portal hypertensive gastropathy and its severity in patients with and without cirrhosis. METHODOLOGY: The study was conducted at a tertiary care hospital in Pakistan from April 2021 to May 2022. Liver cirrhosis was diagnosed by clinical manifestations, ultrasonography, and laboratory investigations. The severity of liver cirrhosis was assessed using the Child-Pugh scoring system. The association of H. pylori with portal hypertensive gastropathy in patients with and without cirrhosis was assessed using the chi-square test. RESULTS: A total of 120 patients participated in the study, of which 40 were without liver cirrhosis, while 80 were with cirrhosis. Among patients with cirrhosis, 24 were in Child-Pugh class A, 26 in class B, and 30 in class C. Of patients with liver cirrhosis who were H. pylori-negative, 37.5% (15/40) had portal hypertensive gastropathy. Of these, 12.5% (5/40) had severe PHG, while 25% (10/40) had mild PHG. Of patients with liver cirrhosis who were H. pylori-positive, 62.5% (25/40) had PHG. Of these, 2.5% (1/40) had severe PHG, while 60% (24/40) had mild PHG. Helicobacter pylori contributed nonsignificantly (p=0.080), showing no association with portal hypertensive gastropathy. CONCLUSION: Helicobacter pylori does not appear to have any significant association to cause or worsen portal hypertensive gastropathy in patients with liver cirrhosis.

Clinical Perspectives of Multiple and Extensively Drug-Resistant Typhoid; result from a tertiary care hospital from Pakistan.

INTRODUCTION: Typhoid fever remains a problem in developing countries, including Pakistan. The emergence of multidrug-resistant and, since 2016, of extensively drug-resistant cases is a continuous challenge for health care workers. The COVID-19 pandemic is making management more difficult. METHODOLOGY: In the present study, a total of 52 confirmed cases of typhoid have been studied during 2019. Detailed clinical features, complications and, lab findings were studied. Typhoid culture and sensitivity were recorded and patients were treated accordingly. Patients were asked about risk factors to aim at informing prevention. RESULTS: Out of the 52 having blood culture positive for Salmonella Typhi 47 (90.4%) and Salmonella Paratyphi 5 (9.6%), 4 (7.7%) were sensitive to first-line (Non-resistant), 11 (21.2%) MDR and 37 (71.2%) patient were XDR. One case was resistant to azithromycin. Nausea, vomiting or, abdominal pain was present in 12 (23%), abdominal distension present in 9 (17.3%), abdominal tenderness in 8 (15.4%), hepatomegaly in 10 (19.2%) and, splenomegaly in 22 (42.3%).There were ultrasound abnormalities in 58% of patients and GI complications in 19% of patients. No significant difference was found in clinical findings and complications between resistant and non-resistant cases. Only 23-27% of patients were aware of typhoid prevention and vaccination measures. CONCLUSIONS: The increasing prevalence of resistance and higher degree of complications seen in typhoid fever raises the concern further about prevention and effective infection management in the community as well as clinical settings. Moreover, judicial use of antibiotics is much needed in developing countries like Pakistan.

Assessment of knowledge of junior doctors and non-specialists about musculoskeletal medicine.

OBJECTIVES: To assess the knowledge and confidence of junior doctors and non-specialists in examining and making a diagnosis of patients with musculoskeletal (MSK) diseases. METHODS: This was a Cross-sectional study of 121 doctors working in medical clinics at a tertiary hospital between October and December 2019. Data were collected using a questionnaire. Doctor's awareness regarding different MSK examination methods including gait, arms, leg, spine (GALS), pediatric gait, arms, leg, spine (pGALS) and regional examination of musculoskeletal system (REMS) was noted. Undergraduate teaching of these methods and use in their daily practice was surveyed. RESULTS: Majority of the doctors lacked awareness about different MSK examination techniques. Awareness about GALS, REMS and pGALS was 44.6%, 59.5% and 18.2% respectively. There was significant correlation of GALS/REMS awareness with the undergraduate teaching and doctor's clinical experience (p-value <0.05). Confidence level of doctors in diagnosing patients with adult MSK pathologies was 55%. Only few doctors were satisfied with their musculoskeletal education (29%). CONCLUSION: The GALS examination is a useful screening tool for junior doctors and non-specialists in a direct access setting to rule out musculoskeletal problems.

Gastrointestinal and Hepatobiliary Complications of Extensively Drug-Resistant Typhoid at a Tertiary Care Hospital in Pakistan.

INTRODUCTION: Typhoid fever is a major health problem in developing countries. Extensively drug-resistant (XDR) typhoid is an emerging threat to world health. The objectives of this study were to report our blood culture proven patients having XDR typhoid and compare the rate of gastrointestinal (GI) and hepatobiliary manifestations and complications of antimicrobial sensitive and resistant strains. MATERIALS AND METHODS: This prospective observational study was carried out at a tertiary care hospital in Pakistan, from January 2019 till August 2020 on all consecutive blood culture proven patients of Salmonella typhi. A total of 57 cases of Salmonella were identified, of which 10 were nonresistant, seven multi drug-resistant (MDR), 39 extensively drug-resistant (XDR), and one was extended-spectrum beta lactamase (ESBL) positive. Alarmingly, one of the S. typhi isolate in addition to the first line drugs, was also resistant to azithromycin. Patients were treated with antibiotics according to antimicrobial susceptibility of the Salmonella in accordance with the World Health Organization (WHO) and Medical Microbiology and Infectious Diseases Society of Pakistan (MMIDSP) guidelines and GI and hepatobiliary complications were recorded. RESULTS: Overall rate of complications was low. Some 10% (1/10) with nonresistant typhoid, 14% (1/7) with MDR, and 15% (6/39) of our patients with XDR typhoid fever had abdominal tenderness (p=0.95). None of the patients had GI bleeding, abdominal abscess, or peritonitis. Some 20% (2/10) patients with nonresistant typhoid, 29% (2/7) with MDR, and 18% (7/39) with XDR typhoid developed acute hepatitis, with greater than three times elevation of liver transaminases. There was no statistically significant difference in the occurrence of hepatitis between these groups (p=0.98). Interestingly, one of our patients with XDR typhoid also developed cholestatic hepatitis. CONCLUSION: There is no significant difference in GI and hepatobiliary complications amongst antimicrobial sensitive and resistant strains of typhoid. However, emergence of resistant strains calls for focus on prevention and judicious use of antimicrobials.

Frequency of Hepatorenal Syndrome Among Patients With Cirrhosis and Outcome After Treatment.

Introduction Hepatorenal syndrome is the third most common cause of admissions among patients with liver cirrhosis and has a high mortality rate. It is a progressive deterioration of renal function in a patient with acute or chronic liver failure. The only definite curative treatment of choice for hepatorenal syndrome is liver transplantation. This study aimed to determine the frequency of hepatorenal syndrome among patients with liver cirrhosis and to determine its outcome after treatment. Patients and Methods This case series prospective study was conducted at the Department of Medicine, CMH Lahore Medical College and Institute of Dentistry, Pakistan, from January 2019 to December 2019. The study included 136 patients of cirrhosis who were identified and worked up for hepatorenal syndrome. The patients with liver cirrhosis diagnosed as having hepatorenal syndrome were given treatment comprising injection terlipressin 2 mg four times a day and injection Haemaccel twice a day for two weeks, and after that the outcome was measured with a follow-up of six weeks. Results A total of 136 patients of cirrhosis were included in the study. Of the patients, 14 (10.3%) were diagnosed as suffering from hepatorenal syndrome. These diagnosed cases were given treatment for two weeks. Three (21.4%) of the patients having hepatorenal syndrome did not show any response, two (14.3%) patients recovered partially, four (28.6%) patients recovered fully, and four (28.6%) expired within one month of the treatment. One (7.14%) patient was referred during the treatment for liver transplant. Conclusions Hepatorenal syndrome is a common complication of cirrhosis. The treatment of systemic vasoconstrictors for hepatorenal syndrome proved to be effective in our study and should be the first priority for treating hepatorenal syndrome especially in places like Pakistan where liver transplantation is not that easily available.

Post cricoid tumours; a limiting factor for percutaneous endoscopic gastrostomy insertion in cancer patients: Results from a tertiary care hospital.

BACKGROUND AND STUDY AIMS: The aim of this study was to review all episodes of PEG insertion in patients with head and neck cancer (HNC) at a cancer specialist centre. PATIENTS AND METHODS: Using a structured data extraction form, we abstracted patients' demographic data and clinical information including the primary site of tumour, TNM staging, whether PEG tube was inserted successfully, any complications resulting from PEG tube insertion and duration the tube was in place. RESULTS: We identified a total of 339 HNC patients who had received at least one attempted PEG tube insertion. The mean age of patients was 49.5 ± 14.5 years and 66% (n: 233/339) were males. 151/ 339 (44.5%) patients had a tumour in the pharynx and nasopharynx, 103/ 339 (30.4%) in oral cavity, 81/ 339 (23.9%) in post-cricoid region and 4 (1.1%) of the patients had a laryngeal carcinoma. Histopathologically, most tumours (75.8%) were squamous cell carcinoma presenting at a T4 (52.6%), N0 (38.3%) and M0 (91.7%) stage. PEG tube was successfully inserted in 303/339 (89.4%) patients. There were 36 PEG failures; 24 (66.6%) in postcricoid and laryngeal tumours, 8 (22.3%) in pharynx/nasopharynx and 4 (11.1%) in oral cavity tumours. Of the 81 patients with post-cricoid tumour, PEG tube was successfully inserted in 57/ 81 (70.3%) of the patients. Age, gender or T stage of the tumour was not found to be statistically significant predictors of PEG failure. The only significant factor was presence of post-cricoid or laryngeal tumours that increased the risk of PEG failure 12 times (95% confidence interval: 3.4 to 42.3). CONCLUSION: PEG tube should be used as a first line feeding option in patients with all type of head and neck cancers, however, the attending clinicians should have this foresight of higher failure rates in patients with post-cricoid tumour.

Enteral stents are safe and effective to relieve malignant gastric outlet obstruction in the elderly.

BACKGROUND: Nausea, vomiting and intolerance to oral intake are usually the first presenting symptoms of gastric outlet obstruction, which not only cause malnutrition and increases chances of aspiration pneumonia but also greatly impair the quality of life. Self expandable metallic stents (SEMS) are both effective and safe to relieve the distressing symptoms of gastric outlet obstruction. The aim of this study was to compare the outcomes of endoscopic enteral stent insertion in malignant gastric outlet obstruction in older versus younger patients. METHODS: Eighty two patients were identified to have undergone SEMs insertion for malignant gastric outlet obstruction. Of these, 26 were ≥65 years (older patient group) and 56 were ≤65 years (younger patient group). These were retrospectively reviewed to assess the success rate and the complications of the procedure. RESULTS: Both groups were comparable in terms of technical success (100 % in older patient group versus 97 % in younger patient group). Clinical success rate, as determined by gastric outlet obstruction scoring system score (GOOSS) was also similar in both groups. Additionally, the rate of complications in both groups was also comparable, 27 % in older patient versus 23 % in younger patients (p = 0.085). CONCLUSION: Enteral stenting for malignant gastric outlet obstruction is effective in the older patient groups with its success rate and complications comparable to younger patient population.

Complications of percutaneous endoscopic gastrostomy tube insertion in cancer patients: a retrospective study.

AIM: Dysphagia, with associated malnutrition is a common feature in up to 64 % of patients with cancers of the head and neck region, the oesophagus and the gastro-oesophageal junction (Donaldson and Lenon Cancer 43(Suppl 5):2036-52, 1979). These patients usually require alternate routes of feeding during treatment. However, these methods of feeding are not without associated complications. This study was carried out to assess the complications associated with percutaneous endoscopic gastrostomy tube insertion, the commonest means of providing nutrition in this patient group. METHODS: Two hundred and sixty patients with successful percutaneous endoscopic gastrostomy (PEG) tube insertion were retrospectively reviewed to assess the complications of the procedure. RESULTS: The overall complication rate was 25 % (65 patients). Fifty-five patients (21 %) patients had minor complications. Ten patients (3.8 %) suffered a major complication, including peritonitis and major peri-PEG infection each in three patients (1.2 %), while oesophageal perforation, collection around the PEG insertion site requiring operative drainage, bleeding from the PEG insertion site and tumour seeding at the gastrostomy site were each seen in one (0.4 %) patient. CONCLUSION: Percutaneous endoscopic gastrostomy tube insertion is a useful means of providing enteral nutrition to patients with swallowing problems. Patients with head and neck cancer who are likely to develop dysphagia should be assessed promptly for PEG tube insertion before the start of radiation. Early recognition and prompt treatment of serious complications can avoid potential fatality associated with PEG tubes.

Outcomes of endoscopic pyloric stenting in malignant gastric outlet obstruction: a retrospective study.

BACKGROUND: Up to 30% of patients with pancreatic cancer and more than 50% of patients with gastric cancer already have incurable disease, with distressing symptoms of gastric outlet obstruction at the time of presentation which require effective palliation. We decided to test the clinical outcomes of endoscopic stent placement in malignant gastric outlet obstruction. METHODS: In a retrospective single institution-based study, the charts of patients who had self-expandable metal stents placed to alleviate malignant gastric outlet obstruction were reviewed. Charts were reviewed to assess improvement in oral intake according to the Gastric Outlet Obstruction Scoring System (GOOSS), and in order to also evaluate technical success and complications of the procedure. RESULTS: 69 patients with successful stent placement were retrospectively evaluated. Within 7 and 28 days after stent placement respectively, 85.5% and 80% benefited from stent insertion, with an increase in the GOOSS score of > 1. Resumption of soft or low residue diet (GOOSS 2-3) was achieved in 53.6% at day 7 and in 62% of patients at day 28, respectively. Of the patients achieving a GOOSS score of 2-3, 17.3% remained on a soft or low residue diet at 24 weeks or at last follow up, while 46% died. Stent related adverse events occurred in 10 patients (14%), including stent blockade in 7 and stent migration in 3 patients. CONCLUSION: Endoscopic enteral stenting promptly increases oral intake in the majority of patients with malignant gastric outlet obstruction and is a safe procedure with a low rate of serious complications.
