Treatment of recurrent malignant pheochromocytoma with a novel approach: A case report and review of literature.

INTRODUCTION: Pheochromocytomas are rare catecholamine-secreting tumors with a high potential for recurrence post-surgery, necessitating prolonged follow-up. This case highlights the diagnostic and therapeutic challenges in managing recurrent pheochromocytoma. CASE PRESENTATION: A 25-year-old female, with a history of left pheochromocytoma treated with adrenalectomy a decade earlier, presented with a right adrenal mass. Despite controlled hypertension, elevated urine metanephrines suggested recurrence. Imaging showed a right adrenal mass and suspicious left paraaortic lymph nodes, confirming the diagnosis of recurrent malignant pheochromocytoma in the left adrenal bed and right adrenal gland, with metastasis to the paraaortic lymph nodes. The patient underwent right adrenalectomy coupled with cytoreductive surgery (CRS) in the form of excision of left-sided adrenal bed recurrence and left paraaortic lymph node dissection, intraoperative radiation therapy (IORT), and hyperthermic intraperitoneal chemotherapy (HIPEC). On follow-up six years later, the patient remains free from recurrence. DISCUSSION: This case illustrates the importance of continued surveillance in pheochromocytoma patients, even those with a low-risk profile. The recurrence in this case, despite a smaller initial tumor size and no genetic predispositions, underscores the unpredictable nature of pheochromocytomas. The successful management with CRS, IORT, and HIPEC emphasizes the need for a personalized and multifaceted treatment approach. CONCLUSION: Pheochromocytoma patients, including those initially considered low risk, require long-term monitoring due to the risk of recurrence. The utilization of CRS, IORT, and HIPEC in this case was pivotal in managing the recurrent and metastatic malignant disease effectively, demonstrating the significance of a comprehensive, multidisciplinary treatment strategy in such complex cases.

Potential relationships between COVID-19 and the thyroid gland: an update.

In this review, I aim to provide a complete overview of recent advances in knowledge regarding severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2)-induced thyroid dysfunction. I discuss the findings regarding the role of SARS-CoV-2 in the development of thyroid dysfunction, including subacute thyroiditis, Graves' disease, non-thyroidal illness, thyrotoxicosis and Hashimoto's thyroiditis during and subsequent to coronavirus disease 2019 (COVID-19). The thyroid gland and the entire hypothalamic-pituitary-thyroid (HPT) axis may represent key targets of SARS-CoV-2. Thyroid dysfunction during and subsequent to COVID-19 has been documented in clinical studies and is usually reversible. Most of the thyroid disorders, including Graves' disease, euthyroid sick syndrome, Hashimoto's thyroiditis and subacute thyroiditis, have been documented as sequelae to COVID-19, and the SARS-CoV-2 virus has been implicated in the aetiology of each. COVID-19 has been suggested to trigger the activation of pre-existing thyroid disease or autoimmunity. Furthermore, patients with uncontrolled thyrotoxicosis are at risk of SARS-CoV-2 infection-related consequences. Because of the neutropenia caused by antithyroid medications, which may obscure the signs of COVID-19, this group of patients should receive special attention. It is suggested that thyroid dysfunction during COVID-19 is caused by direct infection of the thyroid or "cytokine storm"-mediated autoimmune effects on the thyroid.

Huge Right Retroperitoneal Paraganglioma With a High Risk of Surgical Excision Treated Conservatively for 14 Years.

Paraganglioma is an uncommon type of neuroendocrine tumor capable of secreting neuropeptides and catecholamines. Retroperitoneal paragangliomas are rare neoplasms that originate from chromaffin cells that secrete catecholamines in the sympathetic ganglia. Tumor reduction and management of excessive catecholamine secretion are the key treatment goals. Surgery is the choice of treatment modality when tumors are amenable to resection because of their malignant potential. Currently, high-dose metaiodobenzylguanidine (MIBG) radiation and chemotherapy are adjuvant therapy to surgery. This case is reported to demonstrate a good prognosis in a conservatively managed, huge, non-functional retroperitoneal paraganglioma for 14 years. This provides alternative options to the traditional surgical treatment in patients who refuse, are unfit for surgery, or have complex surgery, which carries a high mortality rate with analysis of follow-up modalities. Meanwhile, a review of the relevant literature was conducted in order to figure out the prognosis.

Serum Ghrelin Concentration in Patients With Primary Biliary Cirrhosis (PBC).

INTRODUCTION: The appetite-modulating hormone ghrelin may have a role in the etiology of anorexia which is a serious concern in patients with primary biliary cirrhosis (PBC). This study aims to assess the difference in ghrelin level between cases of PBC and healthy controls matched for age and gender, and to evaluate the level of ghrelin in relation to clinical and laboratory findings among cases. METHODS: Twenty patients with primary biliary cirrhosis and 30 healthy controls matched by gender and age were recruited. The severity of liver disease was determined using the Child-Pugh grading system. Clinical comorbidities such as a history of ascites, gastrointestinal bleeding, and encephalopathy were evaluated. A commercial enzyme-linked immunosorbent assay was used to measure total ghrelin.  Results: PBC cases had a significantly higher average level of ghrelin (2305.3 ± 639.4) pg/mL compared to controls (682 ± 197.3) pg/mL. Furthermore, the minimum reported level in cases was 1258 pg/mL compared to 326 pg/mL in controls, while the maximum level nearly tripled the control's maximum level. In PBC patients, plasma levels of total ghrelin showed a weak positive correlation with age, an inverse correlation with body mass index, and were not associated with gender. The level was significantly higher than those in the controls. Ghrelin was associated with the severity of cirrhosis. Levels of serum ghrelin were higher in patients with associated comorbidities such as a history of ascites, gastrointestinal bleeding, and encephalopathy. CONCLUSIONS: Our study demonstrated elevated serum ghrelin levels in patients with primary biliary cirrhosis. Serum ghrelin was associated with the degree of severity and the presence of related comorbidities. Patients with primary biliary cirrhosis remain anorexic and catabolic despite elevated ghrelin levels, suggesting tissue resistance to this anabolic peptide which could be crucial to understanding anorexia and cachexia in primary biliary cirrhosis.

Evaluation of Serum Levels of Insulin-Like Growth Factor 1 and Insulin-Like Growth Factor-Binding Protein 3 in Patients With Colorectal Cancer: A Case-Control Study.

BACKGROUND/AIM: Limited information is available about the relationship between colorectal cancer (CRC) and serum concentration of insulin-like growth factor 1 (IGF1) and insulin-like growth factor-binding protein 3 (IGFBP3). This study aims to compare the serum levels of IGF1and IGFBP3 in colorectal cancer cases and controls and to assess the relationship between their level and the demographic and histopathological characteristics. METHODS: A case-control study in which 50 patients with colorectal cancer and 50 controls matched by gender and age were compared regarding the demographic characteristics and the level of both IGF1 and IGFBP3. The correlation with different clinicopathological features was assessed. RESULTS: Levels of IGF1 were significantly higher while levels of IGFBP3 were significantly lower among cases compared to control. IGF1 was significantly higher among patients with liver metastasis, lymph node (LN) spread, and lymphovenous invasions and did not show significant association with gender, smoking status, family history, or primary site of colorectal cancer. Lower IGFBP3 was significantly high among patients with liver and lymph node metastasis, lymphovenous invasion, and patients with positive family history. This significant negative correlation was also detected between IGFBP3 levels and the size of the tumor. CONCLUSIONS: High IGF1 levels and low concentrations of IGFBP3 are related to colorectal cancer and were significantly associated with liver metastasis, lymph node spread, and lymphovenous invasions. Further research is recommended to investigate if circulating IGF1 and IGFBP3 levels can be used to identify people at high risk of colorectal cancer and to investigate potential lifestyle or pharmaceutical ways to lower IGF1 bioactivity as a risk reduction strategy.

Awareness, experience, and practice of physicians regarding adult gastroesophageal reflux disease (GERD) in Riyadh, Saudi Arabia.

BACKGROUND AND AIMS: Gastroesophageal reflux disease (GERD) was frequently managed by residents as they are the first physician who encounter the patient. This study was conducted to explore the knowledge and practice of physicians in the treatment of GERD and to compare between residents and consultants regarding their knowledge and practice. METHODOLOGY: A cross-sectional study, self-administered questionnaire. RESULTS: Esophagogastroduodenoscopy (EGD) was the most commonly used method to screen for Barrett's esophagus for symptoms for 5 or more years. The most frequent guideline used was the American College of Gastroenterology (ACG) guideline. The most commonly used diagnostic tool for evaluating uncomplicated reflux disease was upper endoscopy with biopsy. Empiric trial with acid suppression was the most commonly used and proton pump inhibitors (PPIs) was the first-line treatment. The most common combination with PPI was prokinetic drugs, most often domperidone. The preferred maintenance strategy was the 'on demand' maintenance mode. Step-down strategy was commonly recommended. A total of 26% of residents and 37% of consultants could achieve a score of good knowledge. Overall patterns of knowledge and practice of GERD diagnosis and management were comparable between residents and consultants with only minor controversy in their knowledge and practice. CONCLUSION: The overall patterns of knowledge and practice of GERD diagnosis and management are comparable among residents and consultants but still there are areas of controversy and confusion. A good knowledge score was found among only a quarter of residents and 37% of consultants. RECOMMENDATIONS: The public health implications of deviations from evidence-based practice should be studied and implementing evidence-based practice should be emphasized.

Clinical Significance of Hepatocyte Growth Factor and Transforming Growth Factor-Beta-1 Levels in Assessing Disease Activity in Inflammatory Bowel Disease.

Background. Transforming growth factor-beta (TGF-ß) and hepatocyte growth factor (HGF) are inflammatory cytokines which function as key regulators of immunological homeostasis and inflammatory responses. They have been linked to inflammatory bowel diseases (IBD). In this study, we aim to assess the levels of TGF-ß and HGF and other inflammatory markers in patients with IBD and correlate them with the disease activity. Study Design. A cross-sectional study involving 100 patients with ulcerative colitis (UC) and 100 patients with Crohn's disease (CD) and 50 control subjects. TGF-ß and HGF levels were measured and correlated with disease activity. Results and Conclusion. Serum levels of TGF-ß and HGF were significantly higher in IBD patients compared with the control group. In the UC group, the levels of HGF and TGF-ß were significantly higher than in the CD group. Levels of TGF-ß and HGF correlate with the activity of IBD.
