Splenic infarction as a rare complication of infectious mononucleosis due to Epstein–Barr virus infection in a patient with no significant comorbidity: Case report and review of the literature

Abstract We report the case of a 17-y-old boy diagnosed with infectious mononucleosis due to Epstein–Barr virus infection who complained of left upper quadrant pain. A magnetic resonance imaging scan showed a splenic infarct in the enlarged spleen. Other causes of splenic infarction were excluded. Thus, infectious mononucleosis may cause splenic infarction in patients without other comorbidities.

Hypofibrinogenemia induced by tigecycline: a potentially life-threatening coagulation disorder

Abstract A 74-year-old female patient with end-stage renal disease, undergoing periodic hemodialysis, was hospitalized due to infection by multidrug-resistant Acinetobacter baumannii after hip replacement surgery. She was treated with tigecycline, a glycylcycline agent. Subsequently she developed coagulation disorders as substantiated by increased international normalized ratio (INR), prolonged partial thromboplastin time (aPTT), and severe hypofibrinogenemia, followed by transaminasemia, cholestasis, and anemia. Ultrasonography and computed tomography revealed no underlying pathological entities. Tigecycline was discontinued and the patient underwent daily hemodialysis and received multiple fresh frozen plasma transfusions. Additionally, she was treated with colistin. Her clinical and laboratory status improved. We suggest that patients treated with tigecycline should be monitored for changes in INR, aPTT, and fibrinogen levels to avoid severe, life-threatening coagulation disturbances.

Disseminated tuberculosis: A neglected entity in immunocompromised hemodialysis patients

End‐stage renal disease is considered a factor predisposing to increased risk of tuberculosis with frequent extrapulmonary localization. Although extrapulmonary tuberculosis has been observed for decades, disseminated tuberculosis, a major cause of morbidity and mortality in immunocompromised hosts, remains rather neglected. We report an unusual case of an immunocompromised patient with a late diagnosis and delayed treatment of genitourinary tuberculosis that subsequently led to the diagnosis of vertebral and miliary tuberculosis (disseminating tuberculosis). Therefore, increased awareness is warranted from physicians dealing with hemodialysis patients in order to avoid delays in diagnosis and treatment initiation.

Rare Skeletal Complications in the Setting of Primary Hyperparathyroidism

Parathyroid carcinoma represents an extremely rare neoplasm with diverse clinical manifestations which vary from asymptomatic patients to severe complications of hypercalcemia or parathyrotoxicosis while skeletal involvement is rather common. Herein we aimed at presenting a unique case of a young patient with rare aggressive skeletal complications of parathyroid cancer that initially were misdiagnosed. Ossification of the cervical ligamentum flavum and skull tumor illustrates erosive bonny lesions of hyperparathyroidism that in association with previous medical history of recurrent nephrolithiasis and biochemical findings guide the diagnosis. We suggest that increased awareness and holistic approach are needed in order to recognize and further investigate signs and symptoms of hyperparathyroidism.

An Uncommon Presentation of Spontaneous Rectus Sheath Hematoma with Acute Kidney Injury due to Obstructive Uropathy and Prerenal Azotemia

Rectus Sheath Hematoma (RSH) represents an unusual entity which is characterized by acute abdominal pain and tender palpable abdominal mass usually, among elderly patients receiving anticoagulant therapy. We report the case of an 81-year-old woman admitted to our department due to acute abdominal pain and oligoanuria. The patient had recently been hospitalized due to acute myocardial infarction (AMI) and atrial fibrillation (AF) and received both anticoagulant and antiplatelet therapies. The radiological assessments revealed an extended Rectus Sheath Hematoma and bilateral hydronephrosis. Treatment of the hematoma required cessation of anticoagulants and antiplatelet agents, immobilization, blood and fresh frozen plasma transfusion, and administration of vasopressors. The patient recovered gradually and was discharged home fifteen (15) days later.

Preventing the development and progression of diabetic kidney disease: Where do we stand?

Diabetic kidney disease (DKD) is a major factor associated with increased cardiovascular (CV) and all-cause mortality and morbidity in patients with diabetes. Current standard therapy includes intensive management of hyperglycemia and blood pressure control with renin-angiotensin-aldosterone system (RAAS) blockers. Despite the implementation of this strategy, DKD remains the leading cause of end-stage renal disease (ESRD), mainly because of the increasing burden of diabetes mellitus. The aim of this review is to evaluate the available evidence, focusing on the benefit of current treatment in the development and progression of DKD.

Renal manifestations of human brucellosis: First report of minimal change disease

Human brucellosis is considered a great example of the complexity of clinical manifestations possibly affecting multiple organs or systems. Renal manifestations of human brucellosis have been documented in few case reports and one case series. Herein, we present a case of Nephrotic syndrome (NS) due to minimal change disease in the course of acute brucellosis. A 53-year-old male farmer was admitted to our department with acute brucellosis and NS. Renal biopsy revealed minimal change disease. Combined treatment with prednisone (1 mg/kg), rifampicin (600 mg/day), and doxycycline (200 mg/day) was initiated. Complete remission of NS was achieved at the end of the fourth week. One year later, the patient remained in complete remission of NS without any sign of relapse of brucellosis.

Acquired reactive perforating collagenosis and pseudoporphyric bullous dermatosis in a hemodialysis patient.

Hemodialysis patients present with a broad spectrum of specific and nonspecific skin disorders, which rarely coexist. We report an exceptional case of a hemodialysis patient that developed acquired reactive perforating collagenosis and pseudoporphyric bullous dermatosis on the basis of common skin disorders which include hyperpigmentation, pruritus, xerosis cutis, and Linsdays nails. Interestingly, our patient presented with two unusual but distinctive cutaneous dermopathies on the background of other commonly seen skin alterations. The patient was successfully treated with allopurinol and N‐acetylcysteine. Avoidance of potentially triggering factors such as alcohol, sunlight exposure and certain medication was recommended. Thus, increasing clinical awareness, assiduous investigation and early treatment of skin disorders are required to improve the prognosis and quality of life in this patient population.

Unexpected Abscess Localization of the Anterior Abdominal Wall in an ADPKD Patient Undergoing Hemodialysis

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most common monogenic disorders and the leading inheritable cause of end-stage renal disease worldwide. Cystic and noncystic extrarenal manifestations are correlated with variable clinical presentations so that an inherited disorder is now considered a systemic disease. Kidney and liver cystic infections are the most common infectious complications in ADPKD patients. Furthermore, it is well known that ADPKD is commonly associated with colonic diverticular disease which recently has been reported to be linked to increased risk of infection on hemodialysis patients. Herein, we present a case of anterior abdominal wall abscess caused by Enterococcus faecalis in a patient with ADPKD undergoing hemodialysis. Although the precise pathway of infection remains uncertain, the previous medical history as well as the clinical course of our patient led us to hypothesize an alternative route of infection from the gastrointestinal tract through an aberrant intestinal barrier into the bloodstream and eventually to an atypical location.
