ABSTRACT

Neurosyphilis is one form of a multisystemic sexually transmitted disease caused by Treponema pallidum. Although typical presentations of neurosyphilis have become less common in the post-antibiotic era, a rising trend of atypical presentations can mimic other diagnoses like herpes simplex and autoimmune encephalitis. In this case, we diagnosed neurosyphilis in a patient with clinical and radiological features similar to herpes simplex encephalitis. We emphasize the need for a diagnostic approach combining imaging namely MRI, lumbar puncture, and use of treponemal and non-treponemal tests so that neurosyphilis cases with atypical neuroimaging findings are not overlooked.

ABSTRACT

Norovirus (NoV) is one of the most common causes of acute infectious gastroenteritis in the United States (US). The infection is typically short-lasting and self-limiting in immunocompetent hosts. Renal transplant recipients on immunosuppressive therapy are more prone to infectious gastroenteritis that can be caused by various common and opportunistic organisms. NoV infection in renal transplant patients presents as an acute diarrheal illness that may progress to a chronic infection with frequent relapses leading to adverse short-term complications (acute renal injury (AKI) and acute graft rejection from the reduction of the dose of immunosuppressive medications) and possibly long-term morbidities (malabsorption syndrome, and a decline in graft survival). The management of chronic NoV infections in renal transplant patients may be quite challenging, as no specific antiviral treatment is presently approved, and frequent adjustments of immunosuppressive therapy may be required in the setting of reduced renal clearance and the attempts to decrease immunosuppressive effects to enhance the viral clearance.Herein, the authors present a case of persistent NoV in a young female patient with a renal transplant that was associated with recurrent admissions with AKI, gross electrolyte disturbances, and significant weight loss. The relapsing NoV infection has negatively impacted the patient's quality of life and socioeconomic performance.

ABSTRACT

Percutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure that represents an important supportive adjunctive component for patients with primary head and neck squamous cell carcinoma (HNSCC). The HNSCC population is considered a high-risk group for developing critical nutritional deficiency due to a multitude of factors. Nevertheless, as the use of PEG in modern practice is gaining more popularity due to various indications, unusual complications have been increasingly reported. PEG site metastasis from primary HNSCC has emerged as a rare, yet serious oncological phenomenon that warrants careful consideration. The authors report an unusual case of squamous cell carcinoma (SCC) of the hypopharynx that metastasized to the gastric body mucosa through a PEG site. The metastatic SCC presented as massive gastrointestinal bleeding, and esophagogastroscopy revealed an ulcerated mass in the gastric body masquerading as a primary gastric adenocarcinoma. Histopathology and immunohistochemistry examination confirmed metastatic SCC which concurred with the patient's primary hypopharyngeal SCC. The review of the updated literature revealed that a total of 121 cases of this rare oncological entity have been reported to date. Physicians need to be vigilant of the symptoms of PEG site metastasis to accurately diagnose and manage the care of this rare occurrence as it is associated with poor prognosis.

ABSTRACT

Statin-induced immune-mediated necrotizing myopathy (IMNM) is a subtype of IMNM linked to exposure to statins and is characterized by positive anti-hydroxymethylglutaryl (HMG) coenzyme A reductase (HMGCR) antibodies. Although rare, this entity has become increasingly recognized as a cause of proximal muscle weakness, especially with the widespread use of statin therapy. Unlike typical statin-associated muscle symptoms, IMNM myopathy often causes severe muscle injury, and muscle weakness persists or sometimes worsens following the withdrawal of statin therapy. Medical practitioners need to keep a high index of clinical suspicion for statin-induced IMNM in patients taking statins who present with muscle weakness. The disease can be debilitating, and treatment strategies are not well established despite the advances that have been made in the diagnosis. Here we present the clinical characteristics and disease course of two cases of statin-induced IMNM. Both patients presented with progressive proximal muscle weakness and myalgias while on long-term statin therapy without significant improvement in their symptoms following the withdrawal of statin therapy. IMNM was suspected, and both patients were found to have high titers of anti-HMG coenzyme A reductase antibodies and demonstrated microscopic features consistent with a diagnosis of IMNM on muscle biopsy. The patients experienced significant disability due to muscle weakness and required a protracted course of escalated immunosuppressive therapy. Although rare, IMNM should be suspected in patients taking statins who present with muscle weakness that fails to improve or worsens when statins were stopped. Early diagnosis and institution of immunosuppressive therapy are important to prevent the progression of the disease.

ABSTRACT

Nephrogenic ascites or dialysis-associated ascites is a rare condition that develops in patients with end-stage renal disease (ESRD) who have been on long-term hemodialysis. It is characterized by rapidly accumulating ascites that is often recurrent and resistant to standard treatment. The diagnosis typically requires the exclusion of common causes of ascites including possible hepatic, cardiac, malignant, and infectious etiologies. Nephrogenic ascites generally has a poor prognosis. Renal transplantation is the sole definitive cure for this difficult-to-treat clinical entity, however, majority of the affected patients are usually deemed unsuitable candidates for transplantation. In this communication, the authors presented a rare case of nephrogenic ascites that posed a therapeutic challenge in an ESRD patient on regular hemodialysis along with a brief review of the literature regarding the pathogenesis, clinical features, and outcome of nephrogenic ascites.

ABSTRACT

Background: Since December 2019, an outbreak of severe respiratory infection (COVID-19) emerged in the city of Wuhan in China. The knowledge, awareness and practice of medical students toward COVID-19 pandemic is of most importance as it demonstrates their preparedness to deal with this pandemic. The objective of this study is to assess the knowledge, awareness and practice of medical students in Sudan universities about COVID 19. Methodogy: This is a cross-sectional study conducted on 19 universities that have medical schools in Sudan. Data from at least 100 medical students from each university were included in the study. Data were collected using an online questionnaire in April 2020. Statistical analysis was conducted using the Statistical Package for Social Science software, version 25. Results: About 2603 medical students from 19 universities were included. Overall good knowledge and practice were demonstrated by the medical students (88.9%) and (78.6%), respectively. Respondents who answered that the most common clinical symptoms of COVID-19 were the main combination of dry cough, fatigue and fever were (27.7%), and the first initial symptom was headache were (48.3%.). (60.2%) Wear medical masks, (95%) said that avoiding crowded places protects against the spread of COVID-19, and (50.7%) have confidence that Sudan can win the battle against the COVID-19. Finally, (68.8%) agreed that COVID-19 will finally be successfully controlled. Conclusion: This study has found that medical students in Sudan demonstrated good knowledge and good practice toward Covid19.

ABSTRACT

Kaposi sarcoma (KS) is caused by human herpesvirus 8 (HHV-8). Epidemic KS is described in the human immunodeficiency virus (HIV) population with acquired immune deficiency syndrome (AIDS). It primarily affects the skin, but it may uncommonly disseminate to involve extracutaneous sites such as the gastrointestinal (GI) tract, liver, and lungs. In this case report, the authors report a 26-year-old homosexual male who was admitted with acute hypoxemic respiratory failure. He was diagnosed with an HIV infection about five months before index presentation, and he was commenced on highly active antiretroviral therapy (HAART). Physical examination was remarkable for diffuse cutaneous nodules over the lower extremities, back, and oropharynx. Chest imaging revealed diffuse bilateral infiltrates, mediastinal adenopathy, and a persistent bilateral pleural effusion. Extensive diagnostic workup was negative for underlying infectious etiology. Transbronchial biopsy demonstrated proliferated spindle cells that stained positive for HHV-8 in keeping with pulmonary KS. Skin biopsies also concurred with the diagnosis of cutaneous KS. Interestingly, the cluster of differentiation 4 (CD4) count was 647 cells/mm3, and HIV viral load (VL) was 500 copies/ml. This case demonstrated an atypical natural history of pulmonary KS in an HIV patient as pulmonary and disseminated mucocutaneous KS occurred with a relatively higher CD4 count (≥500 cells/mm3). It also reminds pulmonologists and infectious disease specialists to consider pulmonary KS as a differential diagnosis of acute hypoxemic respiratory failure in HIV patients, even in the absence of other clinical and laboratory criteria that define the AIDS stage.

ABSTRACT

Hematogenous spread is fairly an unusual feature for papillary thyroid carcinoma (PTC) in comparison to follicular thyroid carcinoma (FTC). Thoracic spinal metastasis with complicating cord compression is an even rarer manifestation of PTC that was reported in a limited number of cases in the literature. Herein we present a 65-year-old female with a history of PTC on current radiotherapy, status post attempted surgery due to significant tumor burden and intraoperative bleeding, presented with a one-week history of rapidly progressive bilateral lower extremities weakness. Physical examination revealed paraplegia of both lower extremities with areflexia and a sensory level equivalent to the upper thoracic vertebrae. Urgent imaging depicted destructive epidural lesions at T1-T3 vertebrae with thoracic cord compression. Emergent laminectomy and debulking of these lesions were undertaken. Histopathological examination confirmed metastatic PTC. The patient proceeded to further treatment with radiotherapy following her successful neurological recovery. Thoracic vertebral metastasis is an unusual oncological phenomenon of PTC. Metastatic PTC should be considered in patients with a current or remote history of PTC who present with thoracic cord compression. Our case demonstrates that multidisciplinary management is the key to achieving a better outcome for metastatic PTC with thoracic cord compression.
