Suspecting Renal Artery Thrombosis

Renal artery thrombosis is a threatening clinical diagnosis, in which renal infarction may occur. Often misdiagnosed, for mimicking other common diseases, it should be considered in persistent flank pain to improve care and reduce morbidity. We review a case of a healthy, 57 year-old woman with renal artery thrombosis mimicking pyelonephritis and renal calculus obstruction, highlighting features of this clinical condition. An accurate diagnosis is essential for optimal management and prompts treatment, which still remains to be defined.

Spondylodiscitis as Complication of Transrectal Ultrasonography-guided Prostate Biopsy: a Case Report

A 61-year-old man presented with high fever, and severe back and abdominal pain following transrectal ultrasonography (TRUS)-guided prostate biopsy. Diagnosis of spondylodiscitis and psoas abscesses was made based on MRI images of the lumbar tract of the spine. Six-month broad-spectrum antibiotic treatment and immobilization with a girdle overcame the disease without any relapse at the 1-year follow-up. Spondylodiscitis after TRUS-guided prostate biopsy is a rare event, which is not yet included as a major complication of the procedure. It is probably due to the presence of fluoroquinolone-resistant bacteria in faeces. It is, therefore, important to highlight this possibility and to stress the use of targeted antibiotic prophylaxis after rectal flora swabbing with selected antibiotics at sufficient concentrations to be effective.

Free-Floating Thrombi in the Right Atrium Causing Pulmonary Embolism

A 74-year-old man presented to our Emergency Department with acute dyspnoea. His electrocardiogram showed atrial flutter with 2:1 block and a rate of 150 bpm. Initial investigations revealed a D-dimer level of 6.01 mg/dl. Based on the patient’s complaints and the high D-dimer level, computed tomography pulmonary angiography was immediately performed. This showed no evidence of pulmonary embolism, but there were pneumatic changes in the right upper lung lobe. Antibiotics treatment was started with pipracillin/tazobactam, after which the patient’s condition improved. However, on the third day after admission he developed acute dyspnoea, diaphoresis and cardiopulmonary instability immediately after defecation. To promptly confirm our clinical suspicion of pulmonary embolism, a transthoracic echocardiography was carried out. This demonstrated a worm-like, mobile mass in the right heart. The right ventricle was enlarged, and paradoxical septal motion was present, indicating right ventricular pressure overload. The systolic tricuspid valvular gradient was 56 mmHg. The patient was treated with thrombolysis. His condition was greatly clinically improved after 3 hours. After 10 days of hospitalization, the patient was discharged.

Hashimoto’s Encephalopathy: An Unusual Cause of Autoimmune Encephalopathy in a Clinically and Biochemically Euthyroid Patient

Objectives: To highlight the occurrence of Hashimoto’s encephalopathy – a steroid-responsive encephalopathy associated with elevated antithyroid antibodies. Material and methods: We describe a clinically and biochemically euthyroid patient with an encephalopathy presenting with headache, mild confusion and personality changes for 6 weeks and tonic–clonic seizures upon admission Results: There was no obvious infective or metabolic cause. The patient had a high titre of antithyroid antibodies and responded to steroid therapy. Conclusion: This uncommon disease needs to be considered in patients presenting with neurological symptoms that remain unexplained after routine standard investigations, even when the patient is euthyroid. Early diagnosis is important, as this is a treatable condition.

An Unusual Complication of Transthoracic Lung Biopsy

Objectives: We report a case of a frail older adult affected by Chilaiditi syndrome complicating transthoracic lung biopsy, which has never been presented before in the literature. Materials and methods: After illustration of our case, we review the available literature about Chilaiditi syndrome. Results: Chilaiditi syndrome is a rare disease characterised by the interposition of colonic segments between the liver and diaphragm associated with mild to severe clinical symptoms. Conclusion: Although it is uncommon, Chilaiditi syndrome is a clinical condition that should be recognized early and differentiated from other diseases since it may significantly impair a patient’s prognosis.

A Young Woman with Fever and Cervical Lymphadenopathy

Kikuchi-Fujimoto's disease is a self-limiting and rare disorder of unknown aetiology. The typical presentation includes fever, cervical lymphadenopathy and night sweats. Consequently, it is part of the differential diagnosis of infectious, lymphoproliferative and connective tissue diseases. Histology demonstrates necrotizing histiocytic lymphadenitis. Treatment is symptomatic with non-steroidal antiinflammatory agents, although there are reports of corticosteroid use in complicated cases. We present the case of a 23-year-old woman admitted to hospital for fever and cervical lymphadenopathies, and diagnosed with Kikuchi-Fujimoto's disease.

Hypereosinophilic Syndrome Simulating an Acute Coronary Syndrome

Objectives: to report a case of hypereosinophilic syndrome which presented clinically acute coronary syndrome. Materials and methods: we describe a case of a 69-year-old woman with acute coronary syndrome and peripheral hypereosinophilia. Results: the condition rapidly evolved to severe heart failure. Coronary disease was excluded by cardiac catheterization. Systemic corticosteroid therapy was initiated and further secondary causes of hypereosinophilia were excluded.

Eosinophilic Pneumonia Associated with Rheumatoid Arthritis: Description of a Case Report and Review of the Literature

Rheumatoid arthritis (RA), a systemic inflammatory disease, may induce pulmonary manifestations. We describe a case of longstanding RA presenting with eosinophilic pneumonia (EP). Rare case reports of tissue eosinophilia involving isolated organs in the setting of RA exist in the literature. It has been shown that the production of proinflammatory cytokines activates different cell group and can simultaneously play a role in RA and induce eosinophils infiltration in target tissue. An appropriate lowest possible dosage of steroid therapy is essential, whereas EP may be a rare subset of pulmonary involvement in RA.

An Unusual Case of Cerebral Oedema

Hereditary angioedema (HAE) is a rare genetic disorder transmitted as an autosomal dominant trait, characterized by reduced plasma concentration or by the presence of non-functional C1 esterase inhibitor. Oedema caused by HAE mostly affects the skin and bowel and can induce swelling of genitalia. Oedema can be life threatening if it causes swelling of the larynx with obstruction of the airways. We describe the case of a 52-year-old man who presented a neurological emergency (coma), where the remarkable localization of the clinical manifestation and the unusual symptomatology hindered the correct diagnosis.

Adjuvant Effect of Leuprolide on Stroke: A Case report

Objectives: To contribute to current knowledge on the vascular risk of oestrogens. Materials and methods: A 44-year-old woman received a 11.25 mg Leuprolide exteneded release injection to control bleeding from a 7 cm uterine fibroid tumour; 45 days later, she had a stroke due to right frontal lobe ischaemia. Thrombolysis induced complete remission. Three years previously, while taking a birth control pill, the patient had suffered from a stroke that involved her left temporal lobe. She was heterozygous for Factor V R2 H1299R locus and homozygous for the 4G/4G mutation of the PAI-1 gene. Even though her homocysteine level was normal, the patient was homozygous for the MTHFR C677T mutation and although she had never had severe bleeding, she was also homozygous for Factor XIII V34L. Results and conclusion: This patient’s prothrombotic condition could have been enhanced by leuprolide since its stimulatory effect on oestrogen production would still have been minimally present at the time of cerebral thrombosis.

Severe Acute Dyspnoea of Extra-Thoracic Origin: Experience with Three Primary Thyroid Lymphomas (PTL)

Objectives: To recall the common clinical presenting features of and guide the diagnostic procedures of primary thyroid lymphomas (PTL). Materials and methods: We report on three patients developing an acute dyspnoea and fast evolving neck mass in the thyroid caused by a PTL occurring in our regional hospital in Switzerland between 2009 and 2013. Results: PTL causes a neck mass, dyspnoea and dysphonia and responds well to chemotherapy. Mortality is due to relapse or infectious complications. Conclusion: Acute dyspnoea caused by thyroid disease is uncommon. Nevertheless, it is the main symptom in PTL due to rapid growth and compression of the airways. Chemotherapy should be started promptly.

Primary Melanoma of the Small Intestine with a Metastatic Lymph Mass in the Inguinal Canal: A Case Report

Objectives: We report a case of primary melanoma of the small intestine. Primary intestinal melanoma (PIM) is an extremely rare neoplasm for which the cause is unknown. Materials and methods: A 67-year-old man was admitted to our department due to abdominal pain, constipation, a large, hard inguinal mass and severe anaemia. Results: After laboratory data, imaging techniques and histopathological examination, the diagnosis was confirmed. A surgical resection of the intestinal neoplasm, treatment with BRAF inhibitors and radiation therapy to the inguinal mass were performed. Conclusion: PIM is rare and it is usually difficult to establish its exact origin.

A Rare Manifestation of Crohn's Disease: Sinonasal Granulomatosis. Report of a Case and Review of Literature

Crohn’s disease is a granulomatous inflammatory bowel disease. Its pathologic findings include non-contiguous chronic inflammation and non-caseating granulomas, sometimes with extra-intestinal localizations. Sinonasal manifestations of Crohn’s disease are quite rare and only a few cases have been reported up to date in the worldwide literature. They are characterized by chronic mucosal inflammation, obstruction, bleeding and occasionally septal perforation. We report a case of sinonasal granulomatosis revealing Crohn’s disease in a 22-year-old woman and go over the available literature on sinonasal involvement in Crohn’s disease.

Uveitis and Acute Interstitial Nephritis: What to Expect

A 46-year-old female patient presenting with acute interstitial nephritis and anterior uveitis was admitted. The renal biopsy disclosed the presence of interstitial nephritis, confirming the clinical diagnosis of tubulointerstitial nephritis and uveitis (TINU) syndrome. Treatment with oral steroids was started, with prompt improvement of symptoms and laboratory abnormalities.

Ischemic Stroke as the Initial Manifestation of Neurosyphilis in a Young Adult Patient Positive for Human Immunodeficiency Virus

A 31-year-old man with pontine infarction was referred to our hospital for further evaluation and treatment. At admission, his neurological examination was unremarkable. No lymphadenopathy or skin lesions were found. The Treponema pallidum haemagglutination test, rapid plasma regain test and fluorescent treponemal antibody absorption test of immunoglobulin G were positive in both serum and cerebrospinal fluid (CSF). CSF analysis showed lymphocytic pleocytosis. The patient had male-to-male sexual contact and was found to be HIV positive. Physicians should be aware that acute ischaemic stroke may be the first manifestation of neurosyphilis in a young adult, especially with HIV infection.
