Progesterone Hypersensitivity Induced by Exogenous Progesterone Exposure.

Progesterone hypersensitivity (PH) is a rare hypersensitivity reaction to either endogenous or exogenous progesterone. There are around 200 reported cases of progesterone hypersensitivity in the medical literature. We present the case of a 31-year-old female who presented with cyclical urticaria and angioedema after exogenous progesterone exposure.

Renin-Angiotensin System: Updated Understanding and Role in Physiological and Pathophysiological States.

The classical view of the renin-angiotensin system (RAS) is that of the circulating hormone pathway involved in salt and water homeostasis and blood pressure regulation. It is also involved in the pathogenesis of cardiac and renal disorders. This led to the creation of drugs blocking the actions of this classical pathway, which improved cardiac and renal outcomes.

Osteoporosis in a 60-Year-Old Male With a History of Chronic Myeloid Leukemia Treated With Imatinib Mesylate.

Secondary osteoporosis is defined as a decline in bone mineral density due to any underlying etiology, which usually results in accelerated bone loss than expected for the individual's age or gender. Almost 50-80% of men diagnosed with osteoporosis have secondary osteoporosis. We present a case of a 60-year-old male with secondary osteoporosis with a history of imatinib mesylate-treated chronic myeloid leukemia (CML).

Thyrotoxic Periodic Paralysis With Severe Hypokalemia Precipitated by Acute Alcohol Intoxication in a Patient With Graves' Disease.

We present a case of a 29-year-old male who presented with thyrotoxic periodic paralysis (TPP) precipitated by acute alcohol intoxication. TPP is an endocrine emergency that presents with an episode of acute flaccid paralysis with hypokalemia in the setting of thyrotoxicosis. Individuals who present with TPP are thought to have an underlying genetic predisposition.

Guillain-Barre Syndrome Secondary to the Use of Dabrafenib and Trametinib for the Treatment of Advanced Thyroid Carcinoma.

BRAF V600E mutation in thyroid malignancies is associated with an aggressive phenotype with more rapid tumor growth and higher mortality. V600E is a driver mutation in the BRAF proto-oncogene, where valine (V) is substituted by glutamic acid (E) at amino acid 600. New chemotherapeutic agents targeting the mitogen-activated protein kinase (MAPK) pathway, including direct BRAF inhibitors, have become available and are increasingly used in various advanced thyroid malignancies.

A Clinicopathological Study of Skin Tumors from a Tertiary Care Centre in North India.

Background: There is a huge spectrum of skin tumors which can be confused clinically with malignancies, particularly when they are pigmented or inflamed, and histopathological examination of a biopsy specimen is required to establish a definitive diagnosis and to facilitate appropriate intervention and follow up.

Aim: To evaluate all skin tumors and categorize them according to their origin.

Methods: The present study was conducted over a period of 4 years (July 1, 2013 to June 31, 2017) comprising of 1.

Metastatic Crohn's Disease of the Vulva: A Rare Presentation.

Crohn's disease, a chronic inflammatory granulomatous disease of gastrointestinal tract, may rarely have extra intestinal manifestations. Vulvar Crohn's disease may be contiguous or noncontiguous with the gastrointestinal tract. It can cause significant symptoms and has a major impact on quality of life.

Lamotrigine-induced Systemic Lupus Erythematosus: A Diagnostic Dilemma.

Many drugs are known to cause systemic lupus erythematosus (SLE), however there are no well defined criteria for drug induced lupus erythematosus (DILE). We present a rare case of lamotrigine induced lupus presenting as acute syndrome of apoptotic pan epidermolysis (ASAP).

Palisaded Encapsulated Neuroma: An Unusual Presentation.

Palisaded encapsulated neuroma (PEN) is a distinctive benign neural tumor, which usually presents as a solitary skin-colored papule or a nodule. It is a benign lesion and may clinically mimic a cutaneous neurofibroma, melanocytic nevi, or cutaneous schwannoma. Here we report a rare case of multifocal cutaneous PENs and its differentiation from cutaneous schwannomas, which is possible by histopathology.
