Hyperleukocytosis in Solid Tumors: A Rare Paraneoplastic Syndrome Associated with Poor Prognosis.
Hematological paraneoplastic syndromes are fairly uncommon. While mild leukocytosis in solid tumors is well reported, white blood cell (WBC) count over 50,000 u/L, described as paraneoplastic leukemoid reaction (PLR), is not. ⋯ We report the case of a challenging and burdensome diagnosis of a presumptive hematological paraneoplastic syndrome in a patient with a locally advanced lung cancer admitted in the Internal Medicine ward. After the end of chemotherapy, clinical and laboratory benefit was observed; however, the aggressive course of the disease became clear, with progression and downhill course that was unresponsive to treatment.

Acute hepatic porphyria (AHP) is a group of rare, metabolic diseases where patients can experience acute neurovisceral attacks, chronic symptoms, and long-term complications. Diagnostic biochemical testing is widely available and effective, but a substantial time from symptom onset to diagnosis often delays treatment and increases morbidity. A panel of laboratory scientists and clinical AHP specialists collaborated to produce recommendations on how to enhance biochemical diagnosis of AHP in the USA. ⋯ Substantial PBG elevation confirms an AHP diagnosis and allows for prompt treatment initiation. Additional testing can determine AHP subtype and identify at-risk family members. Increased awareness of AHP and correct diagnostic methods will reduce diagnostic delay and improve patient outcomes.

When too many hits breaks the heart: A case of Radiation Induced Takotsubo Cardiomyopathy.
Takotsubo cardiomyopathy (TCM), or stress induced cardiomyopathy is being increasingly recognized as a cause of acute heart failure. Often seen in women and older individuals with acute stressors, it can cause significant hemodynamic compromise. ⋯ Left ventriculogram revealed apical ballooning, characteristic of TCM. Often linked to physical and emotional stressors, TCM has been found to be more prevalent in patients with malignancies.

Review Case Reports
Alkalemia and Hepatic Encephalopathy in a Chronic Dialysis Patient.
Hepatic encephalopathy (HE) includes cognitive, psychiatric and neuromotor abnormalities observed from brain dysfunction secondary to liver disease and/or porto-systemic shunting. HE can have a wide range of clinical manifestations ranging from trivial lack of awareness, decreased attention span, personality changes to confusion, seizures, coma, and death. ⋯ Alkalemia facilitates the conversion of NH4+ to NH3, which is free to cross the blood-brain barrier exacerbating HE. Prompt recognition and correction of underlying risk factors is central to the management of HE.

Abdominal obesity and brachial-ankle pulse wave velocity (baPWV) are indicators of atherosclerosis. But few studies have shown the relationship between baPWV combined with waist-hip ratio (WHR) and cardiac-cerebrovascular events (CCVEs). ⋯ BaPWV and WHR were important risk factors for CCVEs and had synergistic effects. When baPWV increased, WHR may contribute more to the risk of CCVEs in hypertensive patients.
