Hepatectomy cures a cough: giant cavernous hemangioma in a patient with persistent cough.

Cavernous hemangiomas are the most common type of benign liver tumor. Although these tumors are often asymptomatic, they can occur with an array of symptoms. The authors describe a case of a 51-year-old man who presented to the emergency department with a relentless cough, nausea, and abdominal pain. Results of a computed tomography scan suggested the patient had a giant cavernous hemangioma on his liver; microscopic evaluation confirmed this diagnosis. The hemangioma was initially deemed unresectable and the patient was treated with one session of hepatic artery embolization. The embolization was unsuccessful at easing the patient's symptoms, however, and a hepatic lobectomy and resection was performed. After surgical intervention, the patient's symptoms resolved. The present case illustrates an unusual instance in which chronic cough was cured through hepatectomy for giant cavernous hemangioma. To our knowledge, no reports of coughing as a primary symptom of giant cavernous hemangioma have been previously reported in the literature.

Association of morbid obesity with FTO and INSIG2 allelic variants.

OBJECTIVE: To determine whether 2 single nucleotide polymorphisms (SNPs) in the obesity genes the fat mass and obesity associated gene (FTO) and the insulin induced gene 2 (INSIG2) are associated with class III, or morbid, obesity in patients undergoing bariatric weight loss operations. DESIGN: Retrospective analysis of genotype and clinical data. SETTING: Large rural tertiary care health system. PATIENTS: A total of 707 adult patients with a body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) of at least 40 undergoing open or laparoscopic Roux-en-Y gastric bypass operations for morbid obesity or its comorbid medical problems at Geisinger Medical Center, Danville, Pennsylvania. RESULTS: The mean BMI in the predominantly white female cohort was 51.2. Approximately 21% of patients were homozygous for the FTO obesity SNP variant, 13% were homozygous for the INSIG2 obesity SNP variant, and 3.4% were homozygous for both. Mean BMIs in the groups homozygous for each of these genes were not significantly different from nonhomozygotes. However, FTO/INSIG2 double homozygotes and homozygote/heterozygote pairs had significantly higher BMIs than the other groups. CONCLUSION: Increased BMI in morbid obesity is associated with a combination of FTO and INSIG2 SNPs.

Light promotes regeneration and functional recovery and alters the immune response after spinal cord injury.

BACKGROUND AND OBJECTIVES: Photobiomodulation (PBM) has been proposed as a potential therapy for spinal cord injury (SCI). We aimed to demonstrate that 810 nm light can penetrate deep into the body and promote neuronal regeneration and functional recovery. STUDY DESIGN/MATERIALS AND METHODS: Adult rats underwent a T9 dorsal hemisection, followed by treatment with an 810 nm, 150 mW diode laser (dosage = 1,589 J/cm2). Axonal regeneration and functional recovery were assessed using single and double label tract tracing and various locomotor tasks. The immune response within the spinal cord was also assessed. RESULTS: PBM, with 6% power penetration to the spinal cord depth, significantly increased axonal number and distance of regrowth (P < 0.001). PBM also returned aspects of function to baseline levels and significantly suppressed immune cell activation and cytokine/chemokine expression. CONCLUSION: Our results demonstrate that light, delivered transcutaneously, improves recovery after injury and suggests that light will be a useful treatment for human SCI.
