Priapism is a rare presentation of Chronic Myeloid Leukaemia (CML). It is also considered a medical emergency as delay in treatment may lead to impotence. Prompt medical and surgical interventions such as hydroxyurea, analgesia, phenylephrine injection and aspiration, open surgical shunting, and local radiation therapy are essential. Leukapheresis effectively reduces leukocyte count rapidly and effectively, thereby an important therapy along with other standard of care in CML-induced priapism. In the present case, priapism was the presenting symptom of CML. The same was managed with various modalities such as hydroxyurea, allopurinol, antibiotics, analgesics, sedatives, phenylephrine injection, and aspiration but failed to reduce priapism pain. With a single cycle of leukapheresis, priapism pain could be reduced significantly.

Background And Objective: Reports have suggested the use of intravenous infusion of vasopressors as an approach to prevent spinal anesthesia-induced hypotension (SAIH) in women undergoing cesarean deliveries. However, data on the suitability of this technique for obese people are limited. As such, the current experiment was designed to clarify the dose-response relationship associated with the preventive administration of phenylephrine to avoid SAIH during cesarean delivery in obese parturients under combined spinal-epidural anesthesia.

Background: Intravenous fluid administration and prophylactic vasopressor infusion are the primary methods for preventing spinal anesthesia-induced hypotension during cesarean delivery. However, evidence regarding the impact of different volumes of crystalloid solution on the phenylephrine infusion dosage for preventing this hypotension remains inconclusive. This study aimed to determine the effect of two IV fluid infusion rates (10 or 20 mL/kg/h) on phenylephrine requirement for preventing spinal anesthesia-induced hypotension.

Catecholamine dysregulation is a common feature of multiple acute and chronic cardiac conditions, including heart failure. To investigate the role of altered α-adrenergic stimulation on cardiac function, we developed a short-term exposure model, administering phenylephrine subcutaneously to mice for one week. Compared to vehicle-injected controls, phenylephrine-treated animals exhibited increased ejection fraction, decreased chamber size, diastolic dysfunction and ventricular hypertrophy in the absence of hypertension.

Metabolic reprogramming precedes most alterations during pathological cardiac hypertrophy and heart failure (HF). Recent studies have revealed that Phosphofructokinase, platelet (PFKP) has a wealth of metabolic and non-metabolic functions. In this study, we explored the role of PFKP in cardiac hypertrophic growth and HF.
