Immunoglobulin G4 -related gastrointestinal disease associated with type 1 autoimmune pancreatitis: A case report.

Immunoglobulin G4 (IgG4)-related diseaseis a systemic inflammatory condition of unknown etiology characterized by increases in serum IgG4 and in the number of IgG4-positive cells in affected tissues. One of the commonly involved locations is the pancreas; this condition is known as type 1 autoimmune pancreatitis (AIP). Type 1 AIP, which shows a biliary stricture in the intrapancreatic bile duct, can be misdiagnosed as a malignancy due to similar cholangiography findings and clinical presentation. In rare cases complicated by post-bulbar duodenal ulcers, differentiating between type 1 AIP and malignancies is even more difficult. An 81-year-old male was referred to our hospital for the treatment of a pancreatic head mass and obstructive jaundice. Serological and radiological findings were consistent with both type 1 AIP and a malignancy. Gastroduodenoscopy revealed a post-bulbar duodenal ulcer with endoscopic features that evoked malignant duodenal invasion. Although biopsies were negative for malignant cells, subsequent bleeding from the lesion suggested the progression of malignancy, which led to surgical resection. Pancreatoduodenectomy and pathological examination indicated that type 1 AIP was present. Simultaneously, the involvement of IgG4-related disease in the ulcerative lesion was suggested. To our knowledge, this is the first reported case of type 1 AIP complicated by post-bulbar duodenal ulcers, which was misdiagnosed as malignancy and considered an IgG4-related gastrointestinal disease associated with type 1 AIP.

Incarceration of a part of the gastric wall into the abdominal cavity in a patient with hiatal hernia and complete dislocation of the stomach (upside-down stomach).

An upside-down stomach is a rare type of hiatal hernia. An 83-year-old woman presented to the emergency room with abdominal pain and vomiting. Computed tomography revealed an upside-down stomach and the incarceration of a part of the gastric body into the abdominal cavity. Upper gastrointestinal endoscopy revealed a circular ulcer caused by gastric ischemia. Although she was discharged after 1 week of conservative therapy, she was readmitted to the hospital 1 day after discharge because of a recurrence of hiatal hernia incarceration. She underwent laparoscopic surgery 4 days after readmission and recovered successfully.

Use of low-level laser therapy as an adjuvant therapy for phlebostatic lesions.

Low-intensity laser therapy (LILT) is commonly used as an adjuvant therapy for treating injuries. This integrative literature review was carried out in the MEDLINE, LILACS, CUMED, BDENF, SPORTDiscus, Dentistry & Oral Sciences Source, Academic Source and CINAHL databases. Among the inclusion criteria were: range from 2011 to 2021, in English, Portuguese and Spanish and any study, with the exception of preprints and books. The question was answered: "What is the effectiveness described in the literature of using low-intensity laser therapy (LILT) in the treatment of venous lesions?" The wavelength used in studies varied from 635 nm of red ray to 780 nm of infrared ray, generating healing improvement at any length. LBI presented itself as a low-cost and easy-to-apply adjuvant option, alleviating pain complaints and improving healing in patients with vasculogenic lesions.

The protective effect of benfotiamine on gastric ulcers in male rats: an experimental study.

Gastric ulcers are a common gastrointestinal disorder associated with significant morbidity and mortality. It can also increase the risk of gastric cancer. This study aimed to investigate the effect of benfotiamine on experimentally-induced gastric ulcers in male rats. In this study, 30 Wistar male rats were divided randomly into six groups: control (normal), indomethacin, omeprazole, and treatment groups, including 50, 100, and 200 mg/kg of benfotiamine. Gastric ulcer was induced by indomethacin gavage. Omeprazole and different therapeutic doses of benfotiamine were administered for three days. Twenty-four hours after the last treatment, the rats were euthanized, and samples were collected.The results demonstrated that 100 and 200 mg/kg of benfotiamine treatment significantly improved indomethacin-induced gastric tissue damage. Moreover, benfotiamine at 100 and 200 mg/kg effectively attenuated the levels of pro-inflammatory cytokines IL-6 and TNF-α and oxidative stress markers MDA and ROS while increasing the antioxidant GSH. These findings suggest that benfotiamine's gastroprotective effects are mediated through its antioxidant and anti-inflammatory properties, which help mitigate the tissue damage and inflammatory response associated with indomethacin-induced gastric ulcers.However, further research is needed to elucidate the precise molecular mechanisms underlying these beneficial effects and to evaluate the potential therapeutic application of benfotiamine in clinical settings.

Transcatheter Arterial Embolization for Bleeding From the Proper Hepatic Artery Caused by a Duodenal Ulcer: A Case Report.

Although bleeding is the most common complication of peptic ulcer disease, bleeding from the proper hepatic artery is unusual. We report on the case of an 87-year-old woman who presented with melena. An upper endoscopy was performed for a bleeding duodenal ulcer; however, the bleeding could not be controlled. A careful assessment using contrast-enhanced computed tomography (CT) demonstrated that the bleeding source was the proper hepatic artery. Transcatheter arterial embolization of the proper hepatic artery was successfully performed. This case highlights the importance of careful assessment using contrast-enhanced CT to identify the source of bleeding. Endovascular treatment is the first choice of treatment for patients with bleeding from large arteries.

Spontaneous duodenocutaneous fistula: a rare presentation of perforated duodenal ulcer.

Objectives: Fistula formation between the duodenum and the skin of the anterior abdominal wall is a rare complication and reported most often following surgery. To the best of our knowledge, the development of a spontaneous duodenocutaneous fistula in association with duodenal ulcer has only been reported once. Case presentation: A 52-year-old female patient presented at the emergency department with a painful ulcer and erythema on the right abdominal wall. On admission, she was in extremely poor general and nutritional condition. Laboratory analysis revealed inflammation. An empiric antibiotic therapy was initiated; parenteral nutrition, fluid, and electrolyte resuscitation were started. An enterocutaneous fistula was postulated and confirmed by endoscopy identifying a perforated duodenal ulcer. Surgery was not a valuable option and a Foley catheter was inserted through the fistula. During further endoscopic interventions, the Foley catheter was first replaced by a jejunal tube and later by a percutaneous endoscopic gastrostomy with a jejunal limb for enteral nutrition. The fistula output decreased, the local infection was controlled and the nutritional status improved. Conclusions: Three months later the fistula was closed and the gastrostomy tube was removed. After 2 years the patient was in good general and nutritional condition.

Comparison of gastrointestinal bleeding in patients with and without liver cirrhosis.

OBJECTIVES: Upper gastrointestinal bleeding (GIB) in patients has been well-characterized in liver cirrhosis but studies on lower GIB are limited. The clinical characteristics, management and outcomes in patients with and without liver cirrhosis was compared to determine the overall features of GIB in patients with liver cirrhosis compared with non-cirrhotics. METHODS: A retrospective study on cirrhotics hospitalized for GIB 2010-2021, matched with control group of non-cirrhotics (1:4) for upper vs. lower GIB. Patients with overt bleeding leading to hospitalization were included. RESULTS: Overall, 396 patients had cirrhosis, 267 (67%) men, median age 62, alcoholic etiology 177/396 (45%), median MELD 12 (range 6-32). Overall 102 cirrhotics had GIB, matched with 391 non-cirrhotics. Overall 87 (85%) cirrhotic patients had upper and 15% lower GIB. Compared to non-cirrhotics, the cause of GIB was more commonly acute variceal bleeding (AVB) (42% vs. 1%), hemorrhoids 40% vs. 6% (p = 0.002), less commonly gastric ulcer 13% vs. 31% (p < 0.001), duodenal ulcer 9% vs. 29% (p < 0.001), 5% of cirrhotics used NSAIDs vs. 26% of controls (p < 0.001). Rebleeding occurred in 14% of cirrhotics vs. 3% in controls (p < 0.001). Only one cirrhotic patient (1%) died from GIB vs. 0.8% of controls within 45 days. Overall mortality 45 days after hospitalization was 10% in cirrhotics vs. 5% in controls (p < 0.001). CONCLUSIONS: Bleeding from gastric and duodenal ulcers were less common in cirrhotics than in controls. Bleeding from hemorrhoids was more common in cirrhotics. Mortality due to GIB was low in both groups but overall mortality was significantly higher in cirrhotics.

Cutaneous Post-transplant Lymphoproliferative Disorder.

Post-transplant lymphoproliferative disorders (PTLD) involve T- or B-cell proliferation in an immunosuppressed transplant recipient. It usually presents at extra-nodal sites and can affect several organs. Cutaneous manifestations of PTLD are relatively rare and can be very heterogeneous. We report a case of a 36-year-old male cardiac transplant recipient on long-term immunosuppression (ciclosporin, azathioprine, and prednisolone) who presented with a three-month history of a painless ulcer on the right lower leg. A skin biopsy showed a dermal atypical lymphoid infiltrate positive for PAX5, CD20 and MUM1 on immunohistochemistry and EBV with in-situ hybridisation and a 70% Ki-67 cell proliferation index. A whole body fluorodeoxyglucose (FDG) positron emission tomography (PET) scan showed increased tracer uptake corresponding to the site of the cutaneous ulcer, the anterior cortex of the right lower tibia, an area adjacent to the right superficial femoral artery and the right inguinal node. These findings were in keeping with monomorphic B-cell post-transplant lymphoproliferative disorder (PTLD) consistent with diffuse large B-cell lymphoma, non-germinal centre subtype. Cessation of azathioprine and treatment with an anti-CD20 antibody, rituximab, led to clinical resolution of the ulcer and a negative FDG-PET scan, with no disease recurrence to date. We present a rare case of monomorphic PTLD with cutaneous involvement, presenting with a solitary, painless ulcer, which was successfully treated with a reduction in immunosuppression and additional rituximab monotherapy, given the aggressive subtype. PTLD can arise many years post-transplant and is a serious, potentially life-threatening complication. Therefore, early recognition and prompt treatment are of paramount importance.

Microbiological characterization of neuropathic diabetic foot infection: a retrospective study at a Portuguese tertiary hospital.

Diabetic foot infection imposes a significant burden and is the major cause of nontraumatic limb amputation. Adequate patient management with effective antibiotic therapy is crucial.This retrospective cohort study aimed to characterize the microbiology and resistance patterns of moderate to severe neuropathic diabetic foot infection in patients hospitalized at a tertiary referral hospital between January 2020 and June 2023. Deep tissue specimens from ulcers were collected for culture.Sixty inpatients were included (62% male, mean age 59.1 ± 11.5 years). Osteomyelitis was present in 90% of the patients. Among 102 microorganisms (average of 1.91 ± 1.25 pathogens per patient), 60.8% were gram-positive bacteria, 31.4% were gram-negative, 3.92% were anaerobic bacteria, and 3.92% were fungi. Staphylococcus aureus (19%) and Enterococcus faecium (17%) were the most common. Pseudomonas aeruginosa (8%) and bacteria of the Enterobacterales family (24%) accounted for all the isolated gram-negative bacteria. Sixteen percent of Staphylococcus aureus and 67% of coagulase-negative Staphylococci were resistant to methicillin. Resistance to ampicillin was found in 11% of Enterococci. All Pseudomonas aeruginosa isolates were sensitive to piperacillin-tazobactam, ceftazidime, or cefepime. Among the Enterobacterales, resistance rates were 35% for piperacillin-tazobactam, 38% for ceftazidime, 21% for cefepime, and 13% for carbapenems.Although the prevalence of methicillin-resistant staphylococci was lower than that in other studies, carbapenem resistance among gram-negative bacteria warrants attention. This study highlights the importance of understanding local epidemiology for effective diabetic foot infection management and resistance mitigation.

Characteristics of chronic ulcer patients by gender and ulcer aetiology from a multidisciplinary wound centre.

Chronic ulcer patients form a heterogenous group of patients with various medical backgrounds. Cost-effective targeted treatment necessitates more knowledge about specific features related to different subgroups of ulcer patients. Hence, this study aimed to characterize ulcer patients according to gender and ulcer aetiology. A total of 946 consecutively recorded chronic ulcer patients in the Tampere Wound Registry (TWR) were included and data were gathered from the TWR and patient medical records. Comparisons were made between males and females and patients with venous-, arterial or mixed-, diabetic foot-, pressure- and atypical ulcers. Male patients were found to have diabetes, hypercholesterolemia and obesity significantly more often than females (59.2% vs. 39.6%; p < 0.001, 46.5% vs. 33.3%; p = 0.001, 42.7% vs. 35.9%; p = 0.017 respectively), whereas autoimmune diseases were more common among females (30.6% vs. 15.6%; p < 0.001). Recurrence of ulcers was most common among patients with venous ulcers (p < 0.001) and multimorbidity among those with diabetic foot ulcers (p < 0.001). To conclude, males with chronic ulcers would benefit particularly from lifestyle advice, multidisciplinary treatment should be targeted specifically at those with diabetic and arterial or mixed ulcers and preventive measures at those with venous ulcers.

Effects of diabetes-related foot ulcer depth on healing days, cost, and quality of life: A prospective observational study.

The relationship between the depth of the diabetes-related foot ulcers, and the healing days, cost, and QOL was examined.Depth 4 and 5 ulcers, namely beyond the tendons, exhibited significantly longer healing days and higher costs than Depth 2 and 3 ulcers. As for QOL, there were no significant differences in utility values between the depth categories.Results on healing time and cost reiterate the importance of early consultation, especially before the depth becomes deeper than the tendon.

Peer support as pressure ulcer prevention strategy in special school learners with paraplegia.

Background: Adults with spinal cord injuries perceived peer support as beneficial in preventing secondary health conditions, but the role of peer support among adolescent learners with paraplegia in special schools is still unknown. Objectives: To explore the perspectives of current and previous learners with paraplegia on peer support to prevent pressure ulcers in a special school. Method: A qualitative, exploratory, descriptive study design was used. The authors conducted 12 semi-structured telephonic, audio-recorded interviews and a focus group discussion with current and previous learners with paraplegia attending a special school. The interviews were transcribed verbatim and translated, and data were organised using the Nvivo-12 Pro program. Through conducting an inductive thematic analysis categories, sub-themes and themes were identified from the participants' narratives. Results: The participants' perspectives included positive and challenging aspects of peer support reflected in four sub-themes: group-based support, individual peer mentoring, challenges with peer support and the roles of the school physiotherapist regarding peer support. Conclusion: Learners saw peer support as a crucial strategy in preventing and reducing pressure ulcers. Establishing a peer support system with group and individual components in special schools could be a game-changer to end pressure ulcers among learners with paraplegia and ensure better health and educational outcomes. Clinical implications: Physiotherapists in special schools should support peer support initiatives among learners with paraplegia to ensure successful pressure ulcer prevention.

Identifying a perforated prepyloric ulcer during laparoscopy in a patient presumed to have cholecystitis.

Abdominal pain in patients with significant alcohol use and smoking history presents diagnostic challenges due to overlapping clinical features of complications like acute cholecystitis and peptic ulcers. The unreliable physical examinations of intoxicated patients often complicate accurate diagnosis. We present a case of a 56-year-old male with a history of alcoholism and smoking, who presented to the emergency department with nonspecific abdominal pain. Initial imaging suggested cholecystitis, but due to the patient's intoxication, his physical examination was unreliable. During a laparoscopic cholecystectomy, a perforated prepyloric ulcer was unexpectedly discovered, sealed by the gallbladder. This case highlights the limitations of relying solely on imaging for diagnosing abdominal conditions in intoxicated patients. The intraoperative discovery of the perforated ulcer necessitated a shift in the surgical approach, emphasizing the need for flexibility in surgical planning and a high index of suspicion for other abdominal pathologies in patients with significant lifestyle risks. The successful management of this patient through adaptive surgical techniques and comprehensive postoperative care, including Helicobacter pylori eradication therapy, underscores the importance of maintaining a broad differential diagnosis and readiness to adapt surgical plans. This approach is essential for managing complex cases effectively, ensuring that both the immediate surgical issues and underlying causes are addressed to optimize recovery and prevent recurrence.

The effects of ketoprofen and meloxicam on oxidative stress through the glutathione pathway after ketamine-xylazine anesthesia and ulcer induction in rats: A comparative study.

Given that oxidative stress (OS) occurs as one of the complications of general anesthesia and surgical procedures, practicing the best and safest anesthesia regimen can have a significant share in various surgeries. So, this study compared the effects of non-steroidal anti-inflammatory drugs (NSAIDs) such as ketoprofen (KTP) and meloxicam (MLX) on OS through the glutathione pathway after the ketamine-xylazine (K-X) anesthesia and ulcer induction in rats to suggest post-operative regimens with promising analgesic and anti-inflammatory effects. 80 healthy adult male Wistar rats, were examined in this study. To obtain the baseline value cardiac blood collected of five rats, and the remaining 75 animals were randomized into three groups of 25, including (i) the control group receiving physiological serum, (ii) the experimental group 1 taking KTP, (iii) the experimental group 2, administered by MLX and all three groups received K-X combination IP after 30 min. Then, a full-thickness ulcer was induced under standard conditions, and the blood samples were collected from groups at T0, T30m, T60m, T24h, and T48h. The serum levels of the desired markers were measured. The study results revealed that the administration of K-X as an anesthetic agent made some changes in the markers of the OS-related glutathione (GSH) pathway. Moreover, KTP and MLX, significantly (p < 0.05) augmented the reduced GSH (rGSH), lowered the GSSG, increased the total values of the glutathione disulfide (GSSG) and the rGSH, reduced the rGSH/GSSG ratio, and accelerated the glutathione peroxidase (GPx) activity, but they had high inhibitory effects on the glutathione reductase (GR). Accordingly, both drugs could maintain the balance between the OS markers, caused by general anesthesia. In general, KTP can be a suitable regimen in surgeries wherein analgesia is of importance for less than 24 h, but MLX can be a preferable option if longer analgesia is needed for more than 24 h.

Nocardia keratitis: A clinical diagnosis with successful outcome.

Nocardia keratitis is mostly seen in patients with alcoholism, malnutrition, or HIV. Its chronic waxing-and-waning course makes it difficult to diagnose. A 53-year-old male presented with pain and redness in his right eye for the past 3 weeks. The cornea had paracentral ulcer with stromal infiltrates and multiple satellite lesions giving wreath-like appearance suggestive of Nocardia. After corneal scraping, fortified amikacin, moxifloxacin, and cycloplegics were started. Gram stain revealed filamentous, branching Gram-positive bacteria and acid-fast on Ziehl-Neelsen stain confirming our clinical diagnosis. Ulcer completely resolved over 6 weeks. Thus, a high index of clinical suspicion which was further backed by microbiological confirmation aided in expedient management ensuring a successful outcome.

Ascertainment of Helicobacter pylori Infection and Eradication Treatment Using a Nationwide Electronic Health Record Database.

Background and Aims: There are limited contemporary population-based data on Helicobacter pylori epidemiology and outcomes in the United States. Our primary aim was to create a validated cohort of veterans with H pylori testing or treatment using Veterans Health Administration data. Methods: Using Veterans Health Administration structured and unstructured data, we developed and validated 4 algorithms for H pylori infection (3 algorithms) and treatment status (1 algorithm). During the development phase, we iteratively modified each algorithm based on a manual review of random sets of electronic health records (reference standard). The a priori validation goal was to achieve a one-sided 95% confidence lower bound (LB) for positive predictive value (PPV) and/or negative predictive value (NPV) >90%. We applied the Bonferroni correction when both PPV and NPV were relevant. Results: For H pylori infection, we achieved 99.0% PPV (LB = 94.6%) and 100% NPV (LB = 96.4%) for discriminating H pylori positive vs negative status using structured (ie, laboratory tests) and 95% PPV (LB = 90.3%) and 97.9% NPV (LB = 93.9%) using unstructured (ie, histopathology reports) data. Diagnostic codes achieved 98% PPV (LB = 93.0%) for H pylori diagnosis. The treatment algorithm was composed of multiple antimicrobial combinations and overall achieved ≥98% PPV (LB = 93.0%) for H pylori treatment, except for amoxicillin/levofloxacin (PPV<60%). Application of these algorithms yielded nearly 1.2 million veterans with H pylori testing and/or treatment between 1999 and 2018. Conclusion: We assembled a validated national cohort of veterans who were tested or treated for H pylori infection. This cohort can be used for evaluating H pylori epidemiology and treatment patterns, as well as complications of chronic infection.

Cutaneous Anaplastic T-Cell Lymphoma Mimicking a Small Abscess: A Case Report.

Non-healing ulcers display a noteworthy demonstrative challenge for clinicians. While often attributed to common causes like infections, these persistent wounds can occasionally mask a more sinister underlying condition: malignancy. This case report presents a 39-year-old Indian man with a non-healing ulcer on his right gluteal region. Despite initial treatments for a presumed bacterial infection, the ulcer persisted. Biopsy ultimately revealed a malignant neoplasm of possible hematopoietic origin, positive for CD30 and focally positive for CD45. Further investigations, including MRI, FNAC, and X-rays, were indicative of lymphoma. Non-healing ulcers present a challenge due to diverse etiologies. A thorough understanding of potential causes, including infectious, vascular, autoimmune, and malignant etiologies, is crucial for navigating the diagnostic process. This case highlights the critical role of maintaining a broad differential diagnosis for non-healing ulcers and the importance of a biopsy in reaching a definitive diagnosis. Early recognition of malignancy in such cases is essential for optimal patient management. This case underscores the importance of considering malignancy in patients with persistent ulcers and performing biopsies for a definitive diagnosis. While the initial presentation mimicked an infectious process, the biopsy revealed a possible cutaneous anaplastic T-cell lymphoma. Further investigations are necessary to definitively classify the specific lymphoma subtype and guide further treatment decisions.

Phytochemical Index and the Risk of Gastritis/Gastric Ulcer among Korean Adults: A Prospective Cohort Study.

Phytochemicals found in fruits, vegetables, and plant-based foods have potential protective effects against various diseases, including gastric disorders. This study aimed to analyze the longitudinal association between phytochemical intake and the risk of gastritis/gastric ulcer in Korean adults. This was a prospective cohort study, a community-based cohort conducted as part of the Korean Genome and Epidemiology Study, examining the association between phytochemical intake and the risk of gastritis/gastric ulcer in Korean adults. Dietary information was collected using a validated semi-quantitative food frequency questionnaire, and the phytochemical index (PI) was calculated. The study included 7377 Korean men and women aged 40-69 years without gastritis/gastric ulcer at baseline of the Korea Association Resource study in Korea. The incidence of gastritis/gastric ulcer was determined using a survey questionnaire administered by trained staff. Multivariate Cox proportional hazards regression was used to calculate the hazard ratio and 95% confidence interval to determine the association between PI and risk of gastritis/gastric ulcer. During the median follow-up period of 9.50 years, 729 cases were reported. The fully adjusted model showed a significantly lower risk of gastritis/gastric ulcer in the highest PI quartile compared to the lowest (hazard ratio: 0.78, 95% confidence interval: 0.61-0.98), and this association was linear (p for trend = 0.01). This research indicates that incorporating foods abundant in phytochemicals into one's diet could be associated with a reduced risk of developing gastritis/gastric ulcers. These findings underscore the importance of further investigating the role of phytochemical-rich diets in gastrointestinal health, as demonstrated in this study.
