Acute pancreatitis in pregnancy following COVID-19 vaccine: a case report

Background

Since the approval of the Pfizer–BioNTech (BNT162b2) mRNA vaccine for COVID-19 infection, a few adverse effects have been reported. Acute pancreatitis has been reported in a few patients. However, there is currently no research showing a direct relationship between the vaccine and acute pancreatitis. Here, we report a case of acute pancreatitis following Pfizer vaccination in a young healthy pregnant woman without any known risk factors. To our knowledge, this is the first case report of possible vaccine-induced pancreatitis in a pregnant woman.

Case presentation

The patient, a 24-year-old South-Asian female, at 31 weeks of gestation, presented with severe epigastric pain radiating to the back and worsening on lying supine, associated with nausea and vomiting. She was diagnosed with acute pancreatitis with a serum lipase level of 4376 U/L and an ultrasound showing features of pancreatitis. The patient received her first dose of the Pfizer vaccine 1 week prior to these symptoms. Detailed evaluation did not show any etiological cause of pancreatitis. The patient had a spontaneous vaginal delivery and the baby was shifted to the neonatal intensive care unit in a stable condition. A computed tomography scan postpartum (day 2) demonstrated acute interstitial edematous pancreatitis. The patient was managed conservatively in the intensive care unit and discharged home in a stable condition.

Conclusion

This report highlights the importance of a detailed history and evaluation, and the close monitoring of any patient presenting with abdominal pain after vaccination. Acute pancreatitis can be fatal if not picked up early.

Comparison of the mass tissue strength of strawberry fruit between vertical and horizontal compaction

Strawberries have very thin skin that is prone to damage during post-harvest handling. The strength of this fruit mass tissue has a difference between vertical and horizontal directions. Therefore, this study aimed to compare the strength of the strawberry mass tissue between vertical and horizontal directions using a compressive test at different speeds and compressibility levels. The research was conducted by placing a load on the sample from the vertical and horizontal directions. The variations in compression speed were 2, 4, and 6 mm/s, and the compressibility levels were 6, 12, 18, 24, and 30%, respectively. The results showed that the compacting from the vertical direction obtained a combined mechanical response between the fruit structure and mass tissue cells, while from the horizontal direction the mechanical response was only obtained from the fruit structure. Along with the duration of the compacting, mass tissue damage has started to occur. In this phase, the fruit cells begin to break down in the skin causing the mass tissue damage to decrease. The results of this study can be used to develop a more efficient and effective packaging model for strawberries that has never been disclosed before.

Henna-induced acute hemolysis in an elderly woman: a rare case report from the Maldives

Background

Glucose-6-phosphate dehydrogenase enzyme deficiency is the most common enzymopathy in the world with a high prevalence in people of sub-Saharan Africa, Asia, and Mediterranean region. Being an X-linked recessive disorder, majority of the patients are males, and women get affected only if they are homozygous or double heterozygous for G6PD mutants. These patients are usually asymptomatic and present with an acute episode of hemolytic anemia when exposed to certain medications, chemicals, infections, fava beans, or any oxidative stress.

Case presentation

Here, we report a rare case of acute hemolytic anemia in an elderly woman following exposure to henna. On evaluation, she was found to be G6PD-deficient. We postulate that with increasing age, there is an increase in the amount of skewing about 70–90% in women above 70 years old which may lead to hemolysis in G6PD-deficient patients.

Conclusion

We advise all healthcare workers to keep a close eye and screen for G6PD deficiency in all elderly women presenting with acute hemolytic anemia.

Individualizing Time-in-Range Goals in Management of Diabetes Mellitus and Role of Insulin: Clinical Insights From a Multinational Panel

Diabetes mellitus is a global health concern associated with significant morbidity and mortality. Inadequate control of diabetes leads to chronic complications and higher mortality rates, which emphasizes the importance of achieving glycemic targets. Although glycated hemoglobin (HbA_1c) is the gold standard for measuring glycemic control, it has several limitations. Therefore, in recent years, along with the emergence of continuous glucose monitoring (CGM) technology, glycemic control modalities have moved beyond HbA_1c. They encompass modern glucometrics, such as glycemic variability (GV) and time-in-range (TIR). The key advantage of these newer metrics over HbA_1c is that they allow personalized diabetes management with person-centric glycemic control. Basal insulin analogues, especially second-generation basal insulins with properties such as longer duration of action and low risk of hypoglycemia, have demonstrated clinical benefits by reducing GV and improving TIR. Therefore, for more effective and accurate diabetes management, the development of an integrated approach with second-generation basal insulin and glucometrics involving GV and TIR is the need of the hour. With this objective, a multinational group of endocrinologists and diabetologists reviewed the existing recommendations on TIR, provided their clinical insights into the individualization of TIR targets, and elucidated on the role of the second-generation basal insulin analogues in addressing TIR.

A Practitioner's Toolkit for Insulin Motivation in Adults with Type 1 and Type 2 Diabetes Mellitus: Evidence-Based Recommendations from an International Expert Panel

AIM

To develop an evidence-based expert group opinion on the role of insulin motivation to overcome insulin distress during different stages of insulin therapy and to propose a practitioner's toolkit for insulin motivation in the management of diabetes mellitus (DM).

BACKGROUND

Insulin distress, an emotional response of the patient to the suggested use of insulin, acts as a major barrier to insulin therapy in the management of DM. Addressing patient-, physician- and drug-related factors is important to overcome insulin distress. Strengthening of communication between physicians and patients with diabetes and enhancing the patients' coping skills are prerequisites to create a sense of comfort with the use of insulin. Insulin motivation is key to achieving targeted goals in diabetes care. A group of endocrinologists came together at an international meeting held in India to develop tool kits that would aid a practitioner in implementing insulin motivation strategies at different stages of the journey through insulin therapy, including pre-initiation, initiation, titration and intensification. During the meeting, emphasis was placed on the challenges and limitations faced by both physicians and patients with diabetes during each stage of the journey through insulinization.

REVIEW RESULTS

After review of evidence and discussions, the expert group provided recommendations on strategies for improved insulin acceptance, empowering behavior change in patients with DM, approaches for motivating patients to initiate and maintain insulin therapy and best practices for insulin motivation at the pre-initiation, initiation, titration and intensification stages of insulin therapy.

CONCLUSIONS

In the management of DM, bringing in positive behavioral change by motivating the patient to improve treatment adherence helps overcome insulin distress and achieve treatment goals.

Glucocrinology of Modern Sulfonylureas: Clinical Evidence and Practice-Based Opinion from an International Expert Group

AIM

The primary objective of this document is to develop practice-based expert group opinion on certain important but less discussed endocrine and metabolic effects of modern sulfonylureas (SUs) and their usage in the management of diabetes mellitus (DM).

BACKGROUND

Modern SUs may be considered a panacea in DM care with their beneficial extra-pancreatic, pleiotropic, and cardiovascular effects. Safe glycemic control with SUs could be achieved with appropriate patient selection, drug and dosage selection, and patient empowerment. Additionally, sulfonylureas also exhibit certain endocrine and metabolic effects, which could be considered beneficial in the management of DM. In this regard, a group of international clinical experts discussed the less known beneficial aspects of SUs and safe and smart prescription of modern SUs in DM care.

RESULTS

The concept of glucocrinology or the relationship of glycemia with the endocrine system was emphasized during the meetings. Clinical experts arrived at a consensus for the usage of modern SUs in the presence of other endocrine dysfunction and the impact of these drugs on endocrine health. The beneficial pleiotropic and cardiovascular effects of modern SUs were also discussed. The key discussion points were considered to develop clinical expert opinions for the use of modern SUs in persons with DM. Clinical expert opinions were developed for indications, pleiotropic benefits, cardiovascular outcomes, adherence, and safe use of modern SUs.

CONCLUSIONS

Appropriate clinical judgement coupled with a patient-centered approach is crucial to achieve the best outcome in persons with DM. Owing to their safety, efficacy, extra-pancreatic benefits including effects on endocrine and metabolic aspects, and low cost of therapy, modern SUs could be considered as drugs/agents of choice for the treatment of diabetes.

Euthymia in Diabetes: Clinical Evidence and Practice-Based Opinion from an International Expert Group

AIM

To develop an evidence-based expert group opinion on various types of euthymia associated with diabetes mellitus (DM) and its management.

BACKGROUND

Diabetes mellitus is a metabolic syndrome characterized by diverse biomedical and psychosocial features. Emotional health disturbances may lead to psychological and psychiatric dysfunction and may negatively influence glycemic control. Patients with DM may experience diabetes distress (DD) associated with burden of self-care, interpersonal issues, and emotional worries regarding the ability to cope with the illness. Euthymia or a state of positive mental health and psychological well-being should be considered a key outcome of diabetes care. Therefore, to achieve optimal outcomes, the consideration and measurement of psychological and psychiatric aspects along with glycemic levels are very important. A group of multidisciplinary clinical experts came together in an international meeting held in India to develop a workable concept for euthymia in diabetes care. A multidisciplinary approach was suggested to enhance the clinical outcomes and facilitate patient-centered care. During the meeting emphasis was given to the concept of a euthymia model in diabetes care. This model focuses on enhancement of self-care skills in diabetic patients and preventative health awareness among diabetes care providers. Euthymia also encompasses patient-provider communication to aid enhancement of coping skills.

RESULTS

After due discussions and extensive deliberations, the expert group provided several recommendations on implementing the concept of euthymia in DM care.

CONCLUSIONS

Introduction of the concept of euthymia in routine clinical practice is important to improve the quality of life and coping skills in patients with DM. A timely clinical assessment of psychological and psychiatric aspects along with patient-reported outcomes of diabetes contributes to overall health and well-being of affected individuals.

Spectral shifting by dyes to enhance algae growth

The photosynthetic growth action spectrum of a green alga at three bands of visible light (blue, orange, and red) at fixed quanta input and under light-limiting conditions was measured in a batch cultivation system. Quantum efficiencies (biomass dry weight increment per quanta absorbed) were better in the yellow-red region than in the blue region. Results served as a basis for the design and optimization of a dye system that would shift the energy of solar radiation to the required wavelength range by absorbing ultraviolet to blue radiation and emitting in the yellow-red, thus enhancing algae growth. Direct incorporation of dyes into the growth medium, although theoretically expected to enhance growth, in fact resulted in dye decomposition, toxicity to algae and consequently in growth inhibition. Indirect application of dyes in a double tubular reactor (algae inside and dye solution outside) demonstrated growth enhancement for certain dyes with high quantum yields and stability, which had suitable absorption/emission spectra for artificial light sources used. The maximum indirect growth enhancement was obtained using rhodamine 6G at a concentration of 3x10(-5)M with tungsten filament lamp sources.

Increased plasma levels epithelial cell-derived neutrophil-activating peptide 78/CXCL5 in periodontitis patients undergoing supportive therapy

AIM

To investigate the influence of cigarette smoking on plasma epithelial cell-derived neutrophil-activating peptide-78 (CXCL5/ENA-78) and interleukin-6 (IL-6) in supportive therapy periodontitis patients.

MATERIALS AND METHODS

Plasma concentrations of CXCL5/ENA-78 and IL-6 were evaluated in 167 systemically healthy subjects (54 smokers and 113 non-smokers) divided into four groups: non-smokers with periodontitis (n=90), smokers with periodontitis (n=49), healthy non smokers (n=23) and healthy smokers (n=5).

RESULTS

Clinical probing depth (CPD) of smokers with periodontitis were significantly greater than those of non-smoking patients (p<0.05). Although clinical attachment loss (CAL) and the number of deep sites affected were greater in the smokers with periodontitis, these differences were not significant. Periodontitis patients had significantly higher plasma IL-6 and ENA-78 than healthy subjects (p<0.05). There was no significant difference in IL-6 between smokers and non-smokers with periodontitis but CXCL5/ENA-78 concentrations were significantly greater in smokers with periodontitis (p=0.006). Plasma CXCL5/ENA-78 correlated with CPD, CAL and tobacco consumption (all p<0.05).

CONCLUSION

Plasma CXCL5/ENA-78 concentrations are a good systemic indicator of the inflammatory process and disease severity in subjects with periodontitis and in addition are potential indicator of inflammatory effects of cigarette smoking. Further studies are required to elucidate the biological mechanisms underlining this increase in CXCL5/ENA-78.

Diagnosis of pulmonary embolism with helical C.T. scan

OBJECTIVE

To determine the role of helical C.T. scan in the diagnosis of pulmonary embolism.

SETTING

Radiology department, Aga Khan University Hospital. One year prospective study May 2001 to May 2002.

METHODS

Sixty patients suspected of having pulmonary embolism were included in this study. Helical C.T. scan chest was performed from aortic arch to lung bases with intravenous contrast medium. Images were acquired in mediastinal and lung windows. Image interpretation was performed on the console and hard copies for main branch and segmental thrombus.

RESULTS

Fifteen patients were diagnosed of having pulmonary embolism on C.T. scan. Clinical correlation and follow up with pulmonary angiography and Doppler ultrasound of leg was carried out. Pulmonary angiography was performed in one patient with embolectomy done after confirmation of diagnosis. 8 patients had associated DVT confirmed on Doppler sonography. Sensitivity of helical C.T. is 93.75%, specificity 100% and positive predictive value 95.65%.

CONCLUSION

Helical CT scan is a quick, easy and accurate imaging modality for diagnosing pulmonary embolism.

Rectal cancer in the Kingdom of Saudi Arabia: the King Faisal Specialist Hospital experience

BACKGROUND

No survival data have yet been published from the Kingdom of Saudi Arabia for patients with rectal cancer. The present paper reports experience with these patients over an 8-year period.

METHODS

All patients referred to the King Faisal Specialist Hospital (KFSH) between March 1990 and February 1998 for the primary management of rectal cancer were entered into a computerized database. Prior to 1993 patients did not receive adjuvant therapy. Kaplan-Meier survival curves and the log-rank test were used to compare outcome data.

RESULTS

There were 70 men (average age: 55.6 years) and 75 women (average age: 52.8 years). Twelve per cent of patients admitted a family history of colorectal carcinoma (CRC). Twenty-seven per cent of tumours were circumferential. Most tumours were larger than 4 cm and the lowest edge of the majority of tumours was less than 6 cm from the anal verge. Fifty-four per cent of tumours were fixed; 69% of patients received either pre-operative or postoperative radiotherapy. A total of 106 patients underwent 'curative' surgery. Equal numbers of patients had abdomino-perineal resection (APR) and anterior resection (AR) of the rectum. Thirty-five patients received blood peri-operatively (APR, 34%; AR, 12%). Major anastomotic leakage following AR occurred in two patients. Two patients died within 30 days of surgery. Ten patients were lost to follow-up. Following curative AR, eight patients had a distal resection margin of < 2 cm and two patients (Dukes' C) developed local recurrence (25%); 37 patients had a margin > 2 cm and seven developed local recurrence (18.9%). A total of 48 patients underwent curative APR, and four patients developed local recurrence (8.3%). Overall local recurrence was tumour stage-dependent (Dukes' B, 8.8%; Dukes' C, 29.3%). Recurrence was local in 13 patients. Pre-operative radiotherapy seemed to reduce average tumour size (3.6 vs 4.3 cm). The crude overall 5-year survival rate was 39%. The 5-year survival rate for patients with Dukes' stage C cancers following 'curative' surgery was 25%.

CONCLUSION

Curative surgery can be performed with a relatively low requirement for blood transfusion, a low mortality and morbidity, and comparable outcomes to Western studies in spite of the large, low and often advanced stage of the tumours managed. Local recurrence rates following curative resection and re-anastomosis for low rectal cancers may be reduced by resisting patient pressure to avoid stomata.

[Stents for bifurcational coronary lesion]

We describe two cases of coronary angioplasty with stents implantation in bifurcational lesion of the left anterior descending artery and the diagonal branch using new techniques successfully performed. Angiographic reestenosis was not present after seven months in one case and the patient was asymptomatic after six months of clinical follow-up in the other.

[Percutaneous approach for the treatment of unprotected left main coronary stenosis. New perspectives with the use of coronary stents]

We describe a case of coronary stenosis located in an unprotected left main coronary artery, treated primarily and electively with the placement of a coronary stent. As a function of the large mass of myocardium involved, this patient would be considered a classical candidate for direct surgery, because the inherent risk involved with conventional balloon angioplasty, mainly due to the eventual occurrence of acute closure during the procedure. Since the previsibility of the immediate results with the use of coronary stents was significantly improved, we propose this new therapeutic approach for this traditionally surgical case, that has been performed with success and without any complication. This strategy for the treatment of unprotected left main lesions with the elective placement of Palmaz-Schatz stents, has not yet been proposed or applied in our country, and may represent a new universe of indication of percutaneous treatment of coronary artery disease, no longer approaching the left main stem only in special or emergency situations, usually a result of complications of left main manipulation during angioplasty of the coronary system. The patient involved in this case did not show any contraindication for the treatment with conventional open heart surgery.

[Coronary angioplasty through the transradial approach]

We describe a coronary angioplasty procedure performed by transradial approach, on a 53 year old male with a reestenotic lesion in his right coronary artery, done 19 months after the initial dilatation. This is a new technique and has not been applied in our country.

Microbiological Quality of Broilers During Processing in a Modern Commercial Slaughterhouse in Kuwait

The effect of processing procedures and overall environmental and hygienic conditions on the microbiological quality and safety of chicken carcasses was studied in a modern processing plant on two separate days. The level of microorganisms on chicken carcasses was assessed by a neck-skin "maceration" method. Carcasses were heavily contaminated by different types of organisms, including indicator organisms (total aerobics, Enterobacteriaceae , coliforms and Escherichia coli ) and pathogens (e.g., Salmonella , Campylobacter and Staphylococcus aureus ). Microbial levels varied during processing, but the highest levels were detected after scalding and defeathering. Microbial levels did not change during vent opening or evisceration. Spray washing after evisceration did not reduce levels of bacteria. No substantial change occurred in bacteria levels during air-chilling, packaging and cold-storage; however, the finished product was heavily contaminated. In the freshly processed carcasses, mean counts (log colony forming units [CFU]/g neck-skin) of aerobic bacteria Enterobacteriaceae , coliforms, E. coli , Campylobacter and S. aureus were 6.6, 4.5, 4.1, 3.6, 5.2 and 2.7 on the first sampling day, and 6.5, 4.6, 4.9, 3.6,4.7 and 4.1 on the second day. Salmonella was present in all birds examined, including those coming directly from the farm. Major serotypes detected on dressed carcasses were Salmonella ohio , Salmonella enteritidis , Salmonella paratyphi and Salmonella krefeld .

Complications of Mersilene sutures in penetrating keratoplasty

BACKGROUND

After penetrating keratoplasty, many corneal surgeons adjust sutures to reduce astigmatism and then leave the sutures in place indefinitely. Nylon sutures can hydrolyze and break years after surgery. In a series of human penetrating keratoplasties, we studied the use of polyester (Mersilene) sutures that do not hydrolyze.

METHODS

We performed two prospective studies of polyester (Mersilene) sutures in human penetrating keratoplasty done by one surgeon. Study I was a randomized comparison of combined running and interrupted Mersilene and nylon sutures in 45 consecutive eyes. Study II was a case series of single running Mersilene suture with postoperative adjustment of suture tension to manage astigmatism in 23 consecutive eyes. We evaluated the performance of the suture and the control of astigmatism.

RESULTS

The interrupted running suture study demonstrated that interrupted Mersilene sutures were 5.5 times more likely to have handling-related complications than nylon interrupted sutures (p = .01); in addition, they were three times as likely to have tissue-related complications as nylon (p = .16). The running suture study demonstrated an unacceptable complication rate of 69% when Mersilene was used as a single adjustable running suture. At 6 months postoperatively, the median refractive astigmatism for the adjustable cases was 3.37 diopters (mean, 4.03 +/- 2.37 D). Eyes with significant suture-related complications were 2.85 times more likely to have greater than 4.00 D of refractive astigmatism than were eyes without suture-related complications.

CONCLUSIONS

Mersilene is an undesirable suture for use in penetrating keratoplasty.

Inadequacy of a polyester (Mersilene) suture for the reduction of astigmatism after penetrating keratoplasty

Through two prospective studies, we evaluated the use of polyester (Mersilene) sutures in penetrating keratoplasty. Study 1 was a randomized comparison of combined running and interrupted Mersilene and nylon sutures (n = 45). Study 2 was a case series of single running Mersilene with postoperative adjustment of suture tension to manage astigmatism (n = 23). Study 1 demonstrated that Mersilene interrupted sutures were 5.5 times more likely to have handling-related complications compared to nylon (P = 0.01); in addition, they were 3 times as likely to have tissue-related complications as nylon interrupted sutures (P = 0.16). Study 2 demonstrated a complication rate of 69% when Mersilene was used as a single adjustable running suture. At 6 months postoperatively, the median refractive astigmatism for the adjustable cases was 3.37 D (mean, 4.03 +/- 2.37 D). Eyes in Study 2 with significant suture-related complications were 2.85 times more likely to have greater than 4 D of refractive astigmatism than were eyes without suture-related complications. We concluded that Mersilene is an undesirable suture for use in penetrating keratoplasty.

Improved visualization of aortopulmonary collateral arteries by abdominal aortic compression during angiography

Increased filling of aortopulmonary collateral arteries occurs when the descending aorta is obstructed distal to their origin. We used this fact to develop a simple, safe technique for improving angiographic visualization of these arteries. The abdominal aorta is manually compressed against the spine during injection of contrast medium. A slight reflex bradycardia resulted, which probably also enhanced filling of the collateral arteries. In eight infants and children with either pulmonary atresia and a ventricular septal defect or truncus arteriosus communis, excellent visualization was consistently achieved without complication.
