Hyperinsulinism, Insulin Resistance and Impaired Fasting Glucose Revealing an Insulin Autoimmune Syndrome

We report a case of a 55-year-old woman who was evaluated for multiple episodes of late postprandial hypoglycaemia. We diagnosed her condition as insulin autoimmune syndrome (Hirata disease) because of a high insulin autoantibody (IAA) titre in association with high levels of plasmatic insulin and hypoglycaemia in a patient with no history of exogenous insulin administration and the exclusion of other causes of late postprandial hypoglycaemia.

Haemophagocytic Syndrome in a 19-Year-Old Male with Plasmodium falciparum Malaria

Objectives: Infectious agents triggering haemophagocytic lymphohistiocytosis (HLH) primarily involve the herpes virus group. We report a case of HLH precipitated by Plasmodium falciparum. Materials and methods: Clinical and laboratory findings in a patient presenting with fever were collected. After confirmation of acute malaria, anti-malarial treatment was administered. Results: Despite initial favourable evolution, the patient developed fever again together with a worsening of the haematological parameters and increased ferritin levels. A bone marrow biopsy confirmed the diagnosis of HLH. Conclusion: This case illustrates that HLH should be considered in the differential diagnosis of acute malaria in patients with persisting fever and pancytopenia.

Is Aphtous Oral Ulceration Biopsy always Useless?

Objective: To report a case of Behçet’s disease whose diagnosis was only confirmed thanks to an oral aphthous lesion biopsy. Materials and methods: Conventional histopathological analysis of a biopsy of an aphthous oral lesion that had appeared two days previously. Results: A small vein vasculitis with eosinophil and neutrophil granulocytes was evidenced. Conclusion: The presence of a small vein vasculitis was here strongly in favour of Behçet's disease, whereas such a diagnosis was not confirmed according to the International Study Group’s criteria.

Severe Statin-induced Rhabdomyolysis following Cholestatic Hepatitis induced by Amoxicillin-clavulanate

We report the case of an 86-year-old man with a past history of coronary disease admitted to our internal medicine department for severe asthenia and weakness due to rhabdomyolysis. Three days earlier, he had been discharged from a gastroenterology unit with a diagnosis of amoxicillin–clavulanate-induced acute cholestatic hepatitis. A review of his drugs revealed that he had taken atorvastatin 10 mg daily in the previous six years, without clinical or laboratory signs of myopathy. Atorvastatin was therefore stopped, with gradual improvement of the rhabdomyolysis. All concomitant drug therapy needs to be reassessed in elderly patients, especially when they become acutely ill.

Leishmaniasis Mimicking Lymphoma and/or Liver Cirrhosis

A 76-year-old man was admitted to hospital with fever, weight loss, pancytopenia, hepatosplenomegaly and a double monoclonal component IgM-IgG-k, suggesting a diagnosis of myeloma. Bone marrow and liver biopsies disclosed the presence of Donovan bodies, and the titre of anti-Leishmania antibodies was extremely high. After treatment with liposomal amphotericin B, the titre of antibodies fell considerably, while monoclonal components, pancytopenia and clinical symptoms slowly disappeared. Polyclonal γ-globulins are made of innumerable monoclonal components, one of which can appear as a recognizable band and be misdiagnosed as myeloma when representing the high titre of an antibody directed towards a specific antigen.

A Case of Infectious Purpura Fulminans: An Unusual Organism and Method of Diagnosis

Infectious purpura fulminans is a rapidly progressive skin necrosis that carries a mortality rate of 30%. Here, we described a case of infectious purpura fulminans caused by Capnocytophaga diagnosed by a blood film.

Can this be considered a Fondaparinux-induced Thrombocytopenia?

We present a case of an old woman with previously documented heparin-induced thrombocytopenia (HIT), treated with fondaparinux, who presented with thrombocytopenia and venous thrombosis after exposure to a preventive dose of fondaparinux during orthopaedic surgery. Any accidental exposure to heparin was avoided. Other causes of thrombocytopenia were excluded and antigenic tests combined with clinical probability made a diagnosis of HIT likely. Can this be considered a possible case of fondaparinux-related HIT, despite the intense and early decrease in platelets, as usually happens in rapid-onset HIT, and the fact that previous exposure to fondaparinux had occurred 5 months previously?

Chronic Active Hepatitis B with HBV-Associated Nephropathy: Close Resemblance to Lupus Nephritis

We present a rare case of a 23-year-old male incidentally detected with hepatitis B virus (HBV) infection presenting with features suggestive of HBV-associated nephropathy. A renal biopsy specimen suggested a mesangioproliferative glomerulonephritis with a full-house pattern on immunoflourescence consistent with a diagnosis of diffuse lupus nephritis. Glomerular HbeAg and HbsAg antigens were not detectable by immunofluorescence. Antiviral therapy was instituted to suppress viral replication, thereby leading to clinical and virological remission, including that of the glomerulonephritis, without the need for additional immunosuppressant therapy. This case depicts the uniqueness of the presentation of the two conditions mimicking each other, the strategy adopted to prevent the activation of viral replication and the achievement of clinical remission.

Hemophagocytic Lymphohistiocytosis Complicating Myelodysplasia

We describe a 62-year-old patient with a 4-year history of myelodysplasia who later developed striking features that included massive splenomegaly, rapidly evolving visual loss and a sensorimotor polyneuropathy. This led us to consider the diagnosis of haemophagocytic lymphohistiocytosis (HLH). Upon further investigation, we found that he fulfilled the necessary diagnostic criteria for HLH, including the presence of haemophagocytosis of erythroid precursors on bone marrow smear.

Two Cases of Arnold-Chiari Malformation with Respiratory Failure

Arnold–Chiari malformation is defined as downward displacement of the brainstem and cerebellum through the foramen magnum. It has different clinical presentations and four subtypes. It is known that downward migration of posterior fossa components through the foramen magnum and associated lower cranial nerve palsy and brainstem compression can cause respiratory failure. Acute respiratory failure could mark the onset of the disease. Posterior fossa decompression performed to treat primary disease can improve the central sleep abnormalities. As respiratory failure is rarely seen, this paper presents two cases of Arnold–Chiari malformation with respiratory failure.

Bilateral Panuveitis at Etanercept Initiation for Juvenile Idiopathic Arthritis

Introduction: Uveitis is a well-known extra-rheumatological manifestation of juvenile idiopathic arthritis (JIA). Tumor necrosis factor has been used to treat uveitis associated with inflammatory diseases. A new onset uveitis under anti-TNF therapy is uncommon. Case presentation: A 12-years-old male, affected since the age of six years, by a severe form of polyarticular JIA. When etanercept was started, he presented panuveitis bilaterally, so we switched to infliximab with good response. Conclusions: The TNF soluble receptor could be considered as a possible promoter in inducing endogenous new onset uveitis in JIA.

Guillain-Barré Syndrome with Absent Brainstem Reflexes: a Case Report

A 41-year-old man was admitted to an intensive care unit following respiratory arrest. One day prior to admission, he had complaints of nausea and pain involving lower limbs. On the night of admission he developed diplopia, dysphagia, and rapidly progressive quadriparesis. He developed respiratory failure requiring mechanical lung ventilation 24 hours later. On the fifth day of hospital stay the patient became comatose with absent brainstem reflexes and appeared to be brain dead. The cerebrospinal fluid showed albuminocytological dissociation. The electroencephalogram revealed an alpha rhythmical activity. The electrophysiological evaluation revealed an inexcitability of all nerves. Guillain-Barré syndrome was suspected. With supportive treatment the patient had a remarkable recovery and now is able to independently conduct his daily activities.

Editorial: European Journal of Case Reports in Internal Medicine

Modern medicine began in the last half of the nineteenth century when doctors started practising the scientific method at the bedside. However, in his presidential address to the Association of American Physicians in 1979 James Wyngaarden postulated that the clinical scientist was an endangered species. Several reasons for this have been suggested, including “the seductive incomes that now derive from procedure-based specialty medicine”. Others have suggested that it is simply because the things left to be discovered at bedside have become exhausted, and that all the big medical advances will now be made by high-powered institutions.

Development of Myasthenia Gravis in Systemic Lupus Erythematosus

Objectives: To perform a literature review and estimate MG incidence in an SLE cohort. Materials and methods: We searched MEDLINE and PubMed for case reports of SLE and MG. We also calculated MG incidence within our clinical SLE cohort (females only). Results: Eleven articles met our criteria, providing 13 SLE patients who developed MG. The majority were female (84.6%), with the average ages of 25.6 and 33.5 years at diagnoses of SLE and MG, respectively. In 380 SLE female patients followed for 2,850 person-years, one MG case occurred. Conclusion: MG in SLE is a rare event.
