Type 1 diabetes and subcutaneous insulin resistance syndrome treated with pancreas transplantation.

We present a case of subcutaneous insulin resistance syndrome, a rare entity, consisting of subcutaneous and intramuscular insulin resistance, with normal or almost normal sensitivity to insulin when administered intravenously. Its cause is unknown and its treatment is challenging. Our patient required a pancreas transplant.

[Tibial brown tumor as a presentation of primary hyperparathyroidism].

Cystic fibrous osteitis is a complication of a very evolved hyperparathyroidism. Because the determination of calcium, parathyroid hormone and vitamin D have become routine studies, this bone complication is uncommon in western countries. However, it should be considered in the differential diagnosis of hypercalcemia and lytic bone lesions.

[Emphysematous cystitis in an 87 year old man].

Emphysematous cystitis is a complicated form of urinary tract infection, characterized by the presence of air inside the wall and in the light of the bladder, affecting more diabetics, elderly and immunosuppressed. The microorganisms that most frequently cause this entity are Escherichia coli and Klebsiella pneumoniae. Its treatment is based on broad-spectrum antibiotics, bladder catheterization and partial or total cystectomy in severe cases.

Agranulocytosis Induced by Vancomycin. Case Report and Literature Review.

BACKGROUND Vancomycin has been used for decades to treat infections by Gram-positive bacteria, particularly those caused by methicillin-resistant staphylococci. Agranulocytosis is an infrequent complication of this antibiotic, postulated in its genesis a mechanism immune-mediated by antineutrophil antibodies and antineutrophil cytoplasm antibodies (ANCA). Treatment includes discontinuing vancomycin, and granulocyte colony-stimulating factor administration.

Fitz-Hugh-Curtis Syndrome Caused by Gonococcal Infection in a Patient with Systemic Lupus Erythematous: A Case Report and Literature Review.

BACKGROUND Fitz-Hugh-Curtis (FHC) syndrome is a perihepatitis linked to inflammatory pelvic disease. It can be caused by Neisseria gonorrhoeae or Chlamydia trachomatis infections. FHC syndrome usually presents with pain in the right hypochondrium and fever, associated with symptoms and signs of pelvic infection in women.

Takotsubo Myocardiopathy and Hyperthyroidism: A Case Report and Literature Review.

BACKGROUND Takotsubo cardiomyopathy (TM), also called stress myocardiopathy or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction with reversible wall motion abnormalities. TM resembles acute coronary syndrome (ACS) in the absence of coronary artery disease (CAD). In several reports, TM has been described in association with hyperthyroidism, suggesting the potential role of thyrotoxicosis in the pathophysiology.

Intravascular Large B Cell Lymphoma Presenting as Fever of Unknown Origin and Diagnosed by Random Skin Biopsies: A Case Report and Literature Review.

BACKGROUND Intravascular lymphoma (IVL) is a rare lymphoproliferative disorder characterized by the proliferation of large B lymphoma cells within the lumen of small-caliber blood vessels. Clinical features are nonspecific, presenting as a systemic disease with fever and may be life-threatening. Antemortem diagnosis is difficult but may be made with biopsies of affected tissues or with random skin biopsies.
