INTRODUCTION: Segmental cervico facial hemangiomas are defined as those longer than 5 cm, affecting a specific facial area. These lesions can be eventually associated with the PHACE syndrome. Our aim is to propose neonatal treatment with propranolol, showing its efficacy/safety, given the scarce evidence on its neonatal use. CLINICAL OBSERVATION: After written informed consent, four patients with segmental facial hemangioma were treated with propranolol in the neonatal period...

Recent data suggests there are non-trivial amounts of human pharmaceutical conjugates potentially entering environmental surface waters. These compounds could contribute to eliciting toxic effects on aquatic biota either directly or indirectly, via de-conjugation. The need for developing a single method for quantifying both parents and conjugates is necessary. Propranolol (PRO), sulfamethoxazole (SMX), and their respective major conjugates 4-OH-propranolol sulfate (PRO-Sul) and sulfamethoxazole-β-glucuronide (SMX-Glc) were successfully simultaneously extracted through weak anion exchange solid phase extraction cartridges from primary and secondary clarification wastewaters from the North End Winnipeg Water Pollution Treatment Plant in Winnipeg, Canada...

BACKGROUND: Essential tremor is one of the most common movement disorders. Treatment primarily consists of pharmacological agents. While primidone and propranolol are well-established treatments in clinical practice, they may be ineffective in 25% to 55% of patients and can produce serious adverse events in a large percentage of them. For these reasons, it is worth evaluating the treatment alternatives for essential tremor. Some specialists have suggested that pregabalin could be a potentially useful agent, but there is uncertainty about its efficacy and safety...

We reported two cases of hyperthyroidism that developed during induction chemotherapy for advanced germ cell tumors with high serum human chorionic gonadotropin (hCG) levels. Case 1 : An 18-year-old man with mediastinal choriocarcinoma complained of tachycardia and tremor. His pretreatment serum hCG level was 1.37 million mIU/ml. The free thyroxine (fT4) level measured on day 2 of the first course of bleomycin, etoposide and cisplatin (BEP) was elevated to 7.8 ng/dl (<1.7 ng/dl), whereasthe thyroidstimulating hormone (TSH) level was undetectable...

In this work, we first describe the population variability in hepatic drug metabolism using cryopreserved hepatocytes from 5 different donors cultured in a perfused 3D human liver microphysiological system and then show how the resulting data can be integrated with a modeling and simulation framework to accomplish in vitro-in vivo translation. For each donor, metabolic depletion profiles of 6 compounds (phenacetin, diclofenac, lidocaine, ibuprofen, propranolol and prednisolone) were measured, along with metabolite formation, mRNA levels of 90 metabolism-related genes, and markers of functional viability (LDH release, albumin and urea production)...

BACKGROUND: Umbilical cord hemangioma is very rare and may not be detected prenatally. However, it should be considered in differential diagnosis with other umbilical masses because it can cause significant morbidity. METHODS: We report the case of a newborn referred with suspected omphalitis and umbilical hernia. RESULTS: Physical examination showed an irreducible umbilical tumor, the size of olive, with dubious secretion. The initial suspected diagnosis was urachal or omphalomesenteric duct remnants...

Drug-induced torsades de pointes (TdP) is a rare but potentially fatal adverse effect of commonly prescribed medications including cardiac and noncardiac drugs. Importantly, many drugs have been reported to cause the characteristic Brugada syndrome-linked electrocardiography (ECG) abnormalities and/or (fatal) ventricular tachyarrhythmias. Chlorpheniramine and propranolol have the arrhythmogenic effects reported previously. A review of literature revealed a large number of case reports of chlorpheniramine or propranolol use resulting in QTc prolongation, TdP, or both...

Propranolol is becoming the treatment of choice for complicated infantile hemangioma. We report here data on peripheral blood flow, O2-saturation, electrocardiographic PR-interval, left ventricular function, blood pressure and heart rate that were assessed before and during treatment for ≥4 weeks with propranolol 2 mg/kg of body weight daily in 67 infants <12 months of age in normal sinus rhythm and with structurally normal hearts. Management with propranolol was well tolerated in all and did not modify peripheral blood flow, O2-saturation, electrocardiographic PR-interval and left ventricular fractional shortening or ejection fraction...

When wild animals are brought into captivity for the first time, they frequently develop chronic stress symptoms. Animals can develop glucocorticoid dysregulation or changes in the sympathetic nervous system over the course of the first week in captivity. By blocking the action of epinephrine and norepinephrine using α- or β-blockers, we hoped to reduce the degree of chronic stress symptoms exhibited by newly captured house sparrows. We measured corticosterone, heart rate and heart rate variability in 24 house sparrows (Passer domesticus) over the first week of captivity...

BACKGROUND: Infantile hemangiomas are the most common childhood vascular tumors, occurring in 10 % of children aged less than 1 year. Propranolol, a β-adrenergic blocker mainly indicated for hypertension, has proven effective in treating these types of tumors. OBJECTIVE: To evaluate the efficacy and adverse effects of propranolol in Mexican pediatric patients diagnosed with infantile hemangioma, treated with an extemporaneously compounded solution of propranolol...

Infantile hemangiomas (IHs) occur in early infancy and are considered to be one of the most frequent childhood tumors. Poor responsiveness to the treatment and complications are reported in about 10 % of patients. For years, the most common treatments for cutaneous and complicated IHs were corticosteroids, interferon-α, vincristine, laser therapy, or surgical intervention. More recently, treatment with propranolol has been reported with high success rates, both in the cutaneous and complicated form of IHs, and it is now considered to be the first-line treatment for IHs...

A 35-year-old woman with a 9-year history of Grave's disease delivered a male infant weighing 2,210 g at 32 weeks of gestation by caesarean section. The neonate developed thyrotoxicosis and, at the age of 24 h, was treated with oral carbimazole (500 µg every 8 h) and propranolol (2 mg/kg/day in two divided doses). He subsequently developed hypertension on day 4, which required therapy with amlodipine (0.1 mg once daily). Severe hypotension developed within 24 h and required discontinuation of amlodipine, with initiation of intravenous inotropic support with dopamine and dobutamine (at a rate of 20 µg/kg/min)...

Objectives: Evaluation of the outcome and experience in 2 years of management of portal hypertensive gastropathy (PHG) by argon plasma coagulation (APC) in a cohort of Egyptian cirrhotic patients. Methods: This study was conducted over a 2-year period from January 2011 to February 2013. Upper gastrointestinal endoscopy was performed to evaluate the degree and site of PHG. APC was applied to areas with mucosal vascular lesions. Results: In total, 200 cirrhotic patients were enrolled; 12 patients were excluded due to death (n = 6) caused by hepatic encephalopathy (n = 3), hepatorenal syndrome (n = 2), or chronic lymphatic leukemia (n = 1), or did not complete the treatment sessions (n = 6), so 188 patients completed the study...

BACKGROUND: Non-selective beta-blockers (NSBBs), e.g. propranolol, are recommended for prophylaxis of variceal bleeding in cirrhosis. Carvedilol, a newer NSBB with additional anti-α1-adrenergic activity, is superior to propranolol in reducing portal pressure. Repeated HVPG measurements are required to identify responders to NSBB. We aimed to determine whether a single-time HVPG measurement, using acute-hemodynamic-response-testing, is sufficient to predict long-term response to carvedilol, and whether these responders have better clinical outcome...

BACKGROUND: Propranolol has been shown previously to restore bone marrow function and improve anemia after lung contusion/hemorrhagic shock. We hypothesized that daily clonidine administration would inhibit central sympathetic outflow and restore bone marrow function in our rodent model of lung contusion/hemorrhagic shock with chronic stress. METHODS: Male Sprague-Dawley rats underwent 6 days of restraint stress after lung contusion/hemorrhagic shock during which the animals received clonidine (75 μg/kg) after the restraint stress...

A preclinical study demonstrated anti-proliferative and apoptotic effect of propranolol on multiple myeloma (MM) cell. Clinical studies suggested that beta blocker (BB) might impact the prognosis of breast, prostate, colorectal, ovarian, lung, and skin cancer. This retrospective study evaluated the effect of BB in MM disease-specific survival (DSS) and overall survival (OS). Among 1971 newly diagnosed MM patients seen at Mayo Clinic between 1995 and 2010, usage of BB and other cardiac (or antihypertensive) medications were abstracted...

There has been an increasing demand for rapid and sensitive techniques for the identification and quantification of pharmaceutical compounds in human biofluids during the last few decades and surface-enhanced Raman scattering (SERS) is one of a number of physicochemical techniques with the potential to meet these demands. In this study we have developed a SERS-based analytical approach for the assessment of human biofluids in combination with chemometrics. This novel approach has enabled the detection and quantification of the β-blocker propranolol spiked into human serum, plasma and urine at physiologically relevant concentrations...
