Streptococcal Esophagitis in an Immunocompetent Patient: A Rare Sequelae.

Infectious esophagitis (IE) is the leading cause of esophagitis, second only to gastroesophageal reflux disease. Infectious esophagitis is typically observed in immunocompromised individuals due to neutropenia, HIV/AIDS, solid organ malignancies, cancer-directed therapy, or chronic steroid use. The most common causes of IE are herpes simplex virus (HSV), cytomegalovirus (CMV), and Candida albicans. Acute bacterial esophagitis is exceedingly rare, particularly in immunocompetent patients. Herein, we describe a unique case of acute streptococcal esophagitis in a male patient with no pertinent medical history. The patient's substernal chest pain and odynophagia resolved after antibiotic treatment.

Rare case of fecaloma requiring endoscopic intervention in a 24-year-old female.

Fecalomas are a rare potential etiology for constipation experienced in children and the elderly. Large bowel obstructions due to fecalomas are preferably treated conservatively with laxatives and bowel rest. However, in the setting of severe corporostasis, more invasive procedures are required to prevent bowel ischemia and perforation. This case report describes a patient who presented to the emergency department with symptoms of large bowel obstruction and constipation, and she was found to have a fecaloma. Conservative interventions, including bowel rest and the administration of laxatives failed, prompting the need for more invasive therapies. During her admission, multiple flexible sigmoidoscopies were required to alleviate the obstruction. Ultimately, this case demonstrates an encounter of a patient with a sigmoid fecaloma from an unlikely demographic with few risk factors that required endoscopic intervention for treatment.

Optimal surgical approach for mid-transverse colon cancer: a systematic review and meta-analysis.

BACKGROUND AND AIM: The incidence of cancer colon has increased dramatically. In addition, the database lacks a review to analyze the outcomes of surgeries for mid-transverse colon cancer with several recent controversial studies. We aimed to compare the outcomes of extended hemicolectomy versus transverse colectomy for mid-transverse colon cancer. METHOD: PubMed, Scopes, Web of Science and Cochrane Library were searched for eligible studies from inception to 1 December 2022 and a systematic review and meta-analysis were done to detect. RESULTS: According to eligibility criteria, 8 studies (2237 patients) were included in our study. The pooled results of the included studies showed no difference in the 5-year OS, 3-year DFS and 5-year DFS between the two types of surgery (5-year OS, RR = 1.15, 95% CI 0.94-1.39, P = 0.17), (3-year OS, RR = 0.96, 95% CI 0.88-1.06, P = 0.42) and (5-year DFS, RR = 1.21, 95% CI 0.91-1.62, P = 0.20). In addition to that, the recurrence rate and the incidence of complications were similar in the two groups (Recurrence rate, RR = 1.08, 95% CI 0.62-1.89, P = 0.79) and (Complications, RR = 1.07, 95% CI 0.74-1.54, P = 0.72). However, the number of LN harvest and the time of the operation were more in case of extended hemicolectomy. CONCLUSION: Despite harvesting less LN, transverse colectomy has similar oncological outcomes to extended hemicolectomy for mid-transverse colon cancer. In addition to that, there was no significant difference in the incidence of complications between the two surgeries.

The Diagnostic Yield of Endoscopic Ultrasound in Asymptomatic Patients with Unexplained Dilated Common Bile Duct, or Double Duct Sign with Normal Transaminase a Retrospective Study from a Single Urban-based University Endoscopy Center.

Background: Common bile duct dilatation alone or double duct sign (both CBD and dilated pancreatic duct dilatation) and abnormal liver enzymes are highly predictive of biliary disease. This can be identified on ultrasound (US), CT scan, and/or magnetic resonance cholangiopancreatography (MRCP). Unexplained dilatation on imaging might warrant endoscopic ultrasound (EUS) to identify any occult causes. Supporting literature about the importance of using EUS in these conditions is evolving with no clear evidence-based approach to evaluate asymptomatic dilated ducts.We aim to investigate the diagnostic yield of EUS in unexplained CBD dilatation or double duct sign with normal liver enzymes. Method: A retrospective data analysis was conducted from January 2015 to October 2021 on asymptomatic patients with a dilatated CBD of 7 mm or more and 9 mm if the patient had a cholecystectomy history or double duct sign with normal liver enzymes. Result: 32 EUS procedures were indicated for unexplained dilated CBD or double duct sign on imaging with normal liver enzymes. 23 had CBD dilatation alone (72 %), and 9 had a double duct sign (28 %). 20 of the included patients were females (63 %), and 12 were males (37 %), with a mean age of 63.8 ± 17 and 68.2 ± 14 years old, respectively (p = 0.424). The diagnosis after EUS in CBD dilatation alone showed a yield of 56 % as follow; no pathology in 10 (44 %), sludge in 9 patients (39 %), CBD stone in 3 (13 %), malignant stricture in 1 (4 %) (Fig. 1). On the other hand, EUS in those with double duct signs showed a diagnostic yield of 55 %; no pathology in 4 (45 %), pancreatic head adenocarcinoma in 3 patients (33 %), Biliary stone in one patient, and malignant CBD stricture in one patient (11 % each) (Fig. 2). Conclusion: Unexplained CBD dilatation or Double duct sign on imagining in patients with normal liver enzymes should warrant further investigation with EUS to avoid missing serious pathological conditions such as stones, sludge, stricture, or a mass.

Autoimmune hepatitis presenting with concomitant chronic pancreatitis.

Autoimmune Hepatitis (AIH) is a progressive form of chronic hepatitis, with periods of remissions and exacerbations. Diagnosis includes abnormally high levels of immunoglobulins and multiple autoantibodies. Clinical presentation is variable, with a spectrum extending from asymptomatic cases to fulminant liver failure. Symptoms include abdominal pain, malaise, fatigue, and small joint arthralgia. We present a case of a 36-year-old male with a past medical history of alcohol dependence and acute pancreatitis who was diagnosed with AIH. There is limited data regarding patients with concomitant AIH and pancreatitis. Our patient presented with AIH with secondary acute on chronic pancreatitis, in the absence of additional autoimmune manifestations. The mechanism of AIH remains poorly understood; however, there is an association between the HLA gene and AIH. Genetic studies have shown HLA-DRB1*0301 and HLA-DRB1*0401 as primary and secondary genotypes susceptible to AIH, as well as genetic variants with CARD10 and SH2B3. Products secondary to metabolism of ETOH such as alcohol dehydrogenase, malondialdehyde, and acetaldehyde, can lead to development of autoantibodies. Additional research is indicated to evaluate the relationship between AIH and acute pancreatitis.

Hemosuccus Pancreaticus: Challenging Diagnosis and Treatment.

Hemosuccus pancreaticus (HP) is defined as bleeding from the ampulla of Vater through the pancreatic duct. It is a rare complication associated with acute or chronic pancreatitis. The source of bleeding can be from the pancreas itself or surrounding vessels, with the splenic artery most commonly involved. Diagnosing HP is challenging and computed tomography angiography remains the gold standard for diagnosis. We present the case of a 62-year-old male with recurrent pancreatitis complicated with HP. Imaging and endoscopy were consistent with bleeding from the section portion of the duodenum, which resolved without intervention. LEARNING POINTS: Hemosuccus pancreaticus is a rare complication associated with acute or chronic pancreatitis.CT angiography is the gold standard for diagnosing hemosuccus pancreaticus.Arterial embolization is the first-line treatment of hemosuccus pancreaticus.

Erdheim-Chester disease presenting at the central nervous system.

Erdheim-Chester disease is a rare non-Langerhans cell histiocytosis (LCH) that affects different body systems. It was recently recognized as a neoplastic disorder after identifying an activating mutation of the MAPK pathway. Neurological presentations of ECD are rare. We present a case of a 35-year-old male who presented to the emergency department with neck pain, headache and vomiting for 2 months; MRI showed multiple heterogeneous intracranial masses. Neurosurgery performed a suboccipital craniotomy, partially resected the cerebellar mass, and placed a parietal to frontal shunt catheter. Biopsy results from the cerebellar mass demonstrated cerebellar tissue involved by a diffuse proliferation of foamy histiocytes and spindle cells admixed with prominent lymphoplasmacytic infiltrate and positive for CD68, CD163, Factor XIIIa and Fascin. PET scan showed hypermetabolic uptake within the medullary portions of the diffuse abnormal lesions of the distal femurs, tibias, and fibulas, and cardiac MRI was nonsignificant. The patient was started on vemurafenib and continued to show improvement in a 3-month outpatient follow-up.

Encapsulating peritoneal sclerosis in liver transplant.

Encapsulating peritoneal sclerosis occurs due to chronic irritation of the peritoneal surface resulting in inflammation and fibrosis. Encapsulating peritoneal sclerosis usually occurs in patients requiring peritoneal dialysis (PD); however, it may also occur in liver transplant patients. The fibrosis in encapsulating peritoneal sclerosis could be severe enough to cause small bowel obstruction (SBO). Herein, we report a case of encapsulating peritoneal sclerosis secondary to liver transplantation that presented with SBO. The patient was started on Tamoxifen for encapsulating peritoneal sclerosis and evaluated at follow-up without any other intestinal obstruction episodes. This case demonstrates that encapsulating peritoneal sclerosis can occur as a liver transplant complication and present with small bowel obstruction.

Hemophagocytic lymphohistiocytosis presenting as acute coronary syndrome.

Acquired Hemophagocytic Lymphohistiocytosis is a rare and deadly syndrome resulting from an overactive immune system, with uncontrolled activation of macrophages and lymphocytes, hypercytokinemia, and systemic inflammatory response. A 75-year-old male presented with typical anginal pain and was diagnosed with the acute coronary syndrome, which required a percutaneous transluminal coronary angioplasty. Instead of resolving the symptoms, the patient began to exhibit pyrexia and worsening altered sensorium with progressing renal failure, anemia, thrombocytopenia and respiratory failure. This constellation of symptoms caused the patient to require mechanical ventilation and hemodialysis. Upon laboratory analysis, hyperferritinemia provided an indication to the diagnosis of acquired hemophagocytic lymphohistiocytosis. After the initiation of dexamethasone, the patient made a significant recovery and was discharged from the hospital.

Salmonella aortitis successfully treated with antibiotics without surgery.

Aortitis is an inflammation of the aorta that is linked to large vessel vasculitis and other rheumatologic cases. Less often, an infectious etiology of aortitis is diagnosed. Aortitis is associated with high mortality and morbidity and requires a high index of suspicion. Here we present a rare case of aortitis secondary to Salmonella Septicemia treated with six weeks of antibiotics in the hospital without and remained asymptomatic and inflammatory markers normalized at 2 weeks follow up (ESR, CRP, and WBCs).

Epidemiological, Clinical, Microbiological, and Risk Factors of Pyogenic Liver Abscess: An 18-years Retrospective Single-Center Analysis.

Background: A pyogenic liver abscess (PLA) is the most frequently observed subtype of liver abscess in the western world. The disease has been subjected to a remarkable change. We aimed to investigate the recent trend in pyogenic liver abscess's epidemiology, clinical, microbiological, and risk factors features.Methods: A retrospective analysis of medical records was done for the patients diagnosed with PLA from January 2000 to June 2018. The institutional review board approved the study.Results: We identified 113 patients with PLA, 60% were males, with a mean age of 54 ± 20 years, and 58 ± 19 years old for males and females, respectively (p = 0.298), with an increasing annual incidence in 2012-2013, and 2016-2017 (Figure 1). Fever and right upper quadrant abdominal pain were the most common symptoms (65%, 55%, respectively). Forty percent of the patients had Biliary tract diseases like cholecystitis or biliary intervention as cholecystectomy or ERCP, and 20% had diabetes mellitus (Table 1). The abscess culture was obtained in 96 cases, 37 cases were negative (39%), 27 cases showed polymicrobial growth (28%) and 15 cases showed Escherichia coli (16%) (Figure 2). The abscess cultures were mostly negative in the first 5 years, then changed to Streptococcus anginosus, and polymicrobial growth in the last four years.Conclusions: PLA is more common in males with a recent increase in incidence. Culture negative PLA was observed in patients who were empirically treated with antibiotics. Polymicrobial was the most common identifiable organism with a change in the microbiological trend every 5 years.

Encapsulating peritoneal sclerosis in liver transplant

Encapsulating peritoneal sclerosis occurs due to chronic irritation of the peritoneal surface resulting in inflammation and fibrosis. Encapsulating peritoneal sclerosis usually occurs in patients requiring peritoneal dialysis (PD); however, it may also occur in liver transplant patients. The fibrosis in encapsulating peritoneal sclerosis could be severe enough to cause small bowel obstruction (SBO). Herein, we report a case of encapsulating peritoneal sclerosis secondary to liver transplantation that presented with SBO. The patient was started on Tamoxifen for encapsulating peritoneal sclerosis and evaluated at follow-up without any other intestinal obstruction episodes. This case demonstrates that encapsulating peritoneal sclerosis can occur as a liver transplant complication and present with small bowel obstruction.

Patients' reasons for missing scheduled clinic appointments and their solutions at a major urban-based academic medical center.

OBJECTIVE: Patients that do not show up for scheduled clinic appointments affect the quality of healthcare provided. This study aimed to recognize the reasons behind missing scheduled appointments and understand possible solutions from the patient's perspective. METHOD: We included 100 patients that attended the outpatient Medicine clinic in January 2020. Selection criteria were based on missing one or more of the scheduled clinic appointments in the last year. The participants answered a questionnaire to clarify the reasons for missing a scheduled clinic appointment and offer suggestions for a solution. The recruiter, in turn, answered several demographical questions. RESULTS: The study showed a statistically significant difference between the no-show rate in females at 60% compared to males at 40% (P = 0.0023). The no show rate was not significantly affected by the day of the week, time of appointment, or the weather. Forgetting about the appointment was the most common cause (36 subjects). Work-related issues were reported in 17 participants, making it the 2nd most common cause. Not notified about the appointment, Lack of transportation, childcare-related issues, along with other reasons, were less likely reported (Table 2). 11 out of 36 (30%) subjects suggested a reminder text message in their preferred language; meanwhile, 4 others suggested a weekend clinic. CONCLUSION: The patients should be aware of different appointment reminders options and have the freedom to choose a suitable reminder. Patients should be educated about the importance of calling to cancel the appointment since some of the reasons for no show are unpreventable.

COVID-19 Presenting as Acute Bilateral Submassive Pulmonary Embolism in a Young Healthy Female.

Similar symptoms, signs, and laboratory abnormalities between coronavirus disease 2019 (COVID-19) and pulmonary embolism (PE) creates a diagnostic challenge to every physician, and emerging data show an association between COVID-19, hypercoagulable state, and venous thromboembolism. We present a rare case of COVID-19 presented as bilateral sub-massive PE. A 28-year-old COVID-19 positive female with no significant past medical history presented with a dry cough and shortness of breath for three days. Initial laboratory test showed elevated D-dimer, electrocardiogram (EKG) showed right axis deviation, right ventricular strain pattern, and SI QIII TIII pattern, and echocardiogram (ECHO) showed right ventricular dysfunction. Those two bedside tests directed the urgency of chest CT angiography that showed bilateral sub-massive PE. Since EKG finding of SI QIII TIII pattern and right ventricular strain, and ECHO finding of right ventricular dysfunction are well described in PE but not in COVID-19, these bedside diagnostic tools can help identify COVID-19 patients with underlining PEs.

Serum Biomarkers for the Early Detection of the Early-Onset Neonatal Sepsis: A Single-Center Prospective Study.

BACKGROUND: Reducing the hazards of the early-onset neonatal sepsis (EONS) is a priority justifying the further investigation for potential biomarkers for its early diagnosis. PURPOSE: We aimed to investigate the diagnostic value of presepsin, procalcitonin, lactoferrin, interleukin (IL)-6, and IL-8 for the early diagnosis of EONS. METHODS: A prospective comparative study, including 30 cases with highly suspected EONS and 30 matched controls, was conducted. Besides the complete blood count and blood culture, C-reactive protein, procalcitonin, presepsin, IL-6, IL-8, and lactoferrin were measured at the admission and after 72 hours. RESULTS: At the time of the admission, presepsin, procalcitonin, C-reactive protein, and IL-8 were significantly higher in the sepsis group. The levels of presepsin, procalcitonin, and IL-8 significantly decreased after 72 hours of the admission. Presepsin, procalcitonin, IL-8, and IL-6 showed a high diagnostic ability for sepsis at admission with area under the curve of 0.934, 0.798, 0.775, and 0.751, respectively. The cutoff values of presepsin, procalcitonin, IL-8, and IL-6 were 821 pg/mL, 2.3 ng/mL, 54 pg/mL, and 24 pg/mL, with a sensitivity of 88.9%, 72.2%, 83.3%, and 94.4% and specificity of 85.7%, 80.9%, 71.4%, and 52.4%, respectively. Lactoferrin had the lowest diagnostic ability with area under the curve of 0.558. IMPLICATIONS FOR PRACTICE: Presepsin was the most accurate biomarker followed by procalcitonin, IL-8, and IL-6 regarding the early diagnosis and management of EONS. The combination between these biomarkers is highly recommended. IMPLICATIONS FOR RESEARCH: Further studies are needed to investigate the diagnostic ability of the combination of these biomarkers.

Drug-induced Angioedema: A Rare Side Effect of Rosuvastatin.

Hydroxymethyl glutaryl coenzyme A reductase inhibitors (statins) are first-line medication for lowering serum cholesterol levels in the prevention of cardiovascular disease. Angioedema is the swelling of mucosa and submucosal tissue. There are no published cases of drug-induced angioedema involving rosuvastatin. We report a case of a 45-year-old female who presented with episodes of self-resolving edema of face, lips, and tongue after being on rosuvastatin. The patient denied any rash during these episodes and mentioned that self-medication with diphenhydramine did not relieve her symptoms. The patient was hemodynamically stable. The complement component 4 (C4), C1 esterase inhibitor, and complement component 1q (C1q) binding assay were within normal range. Therefore, the diagnosis of hereditary angioedema was effectively ruled out. The temporal relation between rosuvastatin and the development of angioedema and prompt resolution of symptoms after the drug discontinued suggest that rosuvastatin was the most probable culprit in the development of angioedema in our patient.

Pheochromocytoma Secreting Large Quantities of Both Epinephrine and Norepinephrine Presenting with Episodes of Hypotension and Severe Electrolyte Imbalance.

Pheochromocytoma is a rare tumor usually arising from the adrenal medulla (strictly speaking, those arising outside the adrenal gland are called paragangliomas). We report a case of pheochromocytoma presenting as orthostatic hypotension and electrolyte imbalance. A 51-year-old woman was admitted because of vomiting and chest pain. She had fluctuating blood pressure (BP) with episodes of orthostatic hypotension. Computed tomography pulmonary angiogram was performed to rule out pulmonary embolism; it showed a clear chest, but an incidental right suprarenal mass. The biochemical analysis supports the diagnosis of pheochromocytoma. Her electrolyte panel revealed persistently low potassium, calcium, and magnesium levels despite aggressive replacement. We speculated that hypotension was mainly due to vasodilatation caused by excess plasma epinephrine and prescribed doxazosin and a nonselective beta-adrenergic blocker which stabilized BP. The right adrenal tumor excised, and postoperatively she remained hemodynamically stable with no hypotensive episode. Laboratory data taken six weeks after surgery show normal 24-hour urine metanephrine and normetanephrine and normal serum magnesium and calcium levels. This case report highlights the variable presentation of pheochromocytoma. We also discuss the probable mechanisms of electrolyte imbalance in our case.

Follicular Variant of Papillary Thyroid Carcinoma Presented as Autonomous Functioning Thyroid Nodule: A Case Report and Review of Literature.

Follicular variant of papillary thyroid carcinoma (FVPTC) presented as an autonomous functioning thyroid nodule is a rare finding. We reported a case of 70-year-old male presented with complaints of palpitation and heat intolerance. On palpation, we found a thyroid nodule of 4 cm in the left lobe. Thyroid function tests revealed hyperthyroidism, and radioactive iodine uptake scan (RAIU) showed increased uptake in the left lobe consistent with a hot nodule. The probability of the benign nature of hyperfunctioning thyroid nodule discussed but patient requested further workup to rule out any remote possibility of thyroid cancer. We performed a fine needle aspiration (FNA), and the cytological examination suggested the possibility of thyroid carcinoma. The patient underwent total thyroidectomy, and histological examination revealed follicular architecture with nuclear features of papillary carcinoma in 1 cm area of the thyroid nodule. In the review of the literature, we identified the following seven cases of FVPTC arising within a hyperfunctioning thyroid nodule.

Adult-onset Still's Disease in a Female Patient with Schizophrenia: A Case Report and Literature Review.

Adult-onset Still's disease (AOSD) is a rare diagnosis. In small percentage of cases, AOSD is associated with other autoimmune diseases including schizophrenia. Despite the lack of sufficient studies, both conditions may share similar autoimmune pathogenic pathways. Herein we describe a 36-year-old woman with the past medical history of schizophrenia who presented with spiking fevers, arthralgia, evanescent rash and pleural chest pain. She reported developing these symptoms a while after poor compliance with her antipsychotic medication. On admission, physical examination was remarkable for high-grade fever, maculopapular rash, oligo arthralgia, hepatomegaly and lymphadenopathy. Laboratory investigation revealed leukocytosis with neutrophilia and markedly elevated ferritin. The patient met four out of four major, and three out of five minor Yamaguchi criteria for AOSD. The patient started on therapy with corticosteroid. Soon after, her symptoms resolved and most of her biochemical markers went back to normal. We review the literature on co-existence of AOSD with other autoimmune diseases, we also discuss that there may be a correlation between ceasing antipsychotic medication (with known immunomodulatory effect) in a schizophrenic patient and triggering an auto-inflammatory process such as AOSD in a susceptible host. In addition, we discussed the possible similar autoimmune pathway of schizophrenia to pathogenesis of AOSD.
