Venous hum is a benign phenomenon. At rest, 20% of the cardiac output flows to the brain via the internal carotid and vertebral arteries. This drains via the internal jugular veins. The flow of blood can cause the vein walls to vibrate creating a humming noise which can be heard by the subject. Typically, a peculiar humming sound is heard in the upper chest near the clavicle.

This may be confused with a heart murmur. The venous hum is heard throughout the cardiac cycle. The difference is easily detected by placing a finger on the jugular vein when listening to the heart, which will abolish or change the noise. A true heart murmur will be unaffected by this maneuver. The murmur also disappears when the patient is in the supine position or may disappear if the subject turns their head to one side. It is also known by the names "nun's murmur" and "bruit de diable" (the Devil's noise).

While a venous hum may provoke consultation with a health care professional, it is entirely harmless.

• A case of severe thallium poisoning successfully treated with hemoperfusion and continuous veno-venous hemofiltration.

• Huang C1, Zhang X, Li G, Jiang Y, Wang Q, Tian R.Author information 11Department of Emergency, 307 Hospital of PLA, Beijing, China.AbstractThallium poisoning is a rare condition that is often misdiagnosed, delaying appropriate treatment. Left untreated, thallium toxicity can permanently damage the nervous and digestive systems or, in severe cases, lead to paralysis and death. It is most often treated by an oral administration of Prussian blue. Thallium has a long physiological half-life, and Prussian blue cannot sequester thallium outside the digestive tract. Therefore, the first priority in treating severe thallium poisoning is to lower blood levels as soon as possible. We report the case of a patient with supralethal blood levels of thallium treated successfully using combined hemoperfusion (HP) and continuous veno-venous hemofiltration (CVVH). Three rounds of HP alone decreased blood thallium levels by 20.2%, 34.8%, and 32.2%, while each of the five subsequent rounds of CVVH reduced thallium blood levels by 63.5%, 64.2%, 42.1%, 18.6%, and 22.6%. The reversal of symptoms and prevention of lasting neurological damage indicates that HP, CVVH, 2,3-dimercaptopropane-1-sulfonate, neuroprotective agents along with supportive therapy were used successfully to treat a case of severe thallium poisoning.

• Increased plasma norepinephrine levels in previously pre-eclamptic women.

• Lampinen KH1, Rönnback M2, Groop PH2, Nicholls MG3, Yandle TG3, Kaaja RJ4.Author information 11] Department of Obstetrics and Gynecology, Helsinki University Central Hospital, Helsinki, Finland [2] Folkhälsan Research Center, Biomedicum, Helsinki, Finland [3] Department of Obstetrics and Gynecology, Karolinska, Stockholm, Sweden.21] Folkhälsan Research Center, Biomedicum, Helsinki, Finland [2] Division of Nephrology, Department of Medicine, Helsinki University Central Hospital, Helsinki, Finland.3Department of Medicine, University of Otago-Christchurch, Christchurch Hospital, Christchurch, New Zealand.4University of Åbo, Satakunta Central Hospital, Björneborg, Finland.AbstractA history of pre-eclampsia increases the risk of cardiovascular morbidity by mechanisms yet unknown. The aim of the present study was to assess whether plasma norepinephrine (NE) levels are increased 5-6 years after pre-eclamptic pregnancy and to investigate associations with pathophysiological mechanisms of cardiovascular disease: insulin sensitivity, vascular function and arterial pressure. A total of 28 women with previous pre-eclampsia and 20 controls were examined. Blood pressure (BP) and plasma levels of NE and endothelin-1 (ET-1) were measured at rest and after standing for 5 min. Insulin sensitivity was assessed with minimal model analysis and vascular function was assessed using venous occlusion plethysmography and pulse wave analysis. Twenty-four-hour BP measurements were carried out. Women with previous pre-eclampsia had higher levels of NE at rest (P=0.02), which did not associate significantly with insulin sensitivity or overall vasodilatory capacity. The 24-h mean of systolic and diastolic blood pressures (BPs) and heart rate did not differ between the groups (P=0.30, P=0.10 and P=0.46, respectively), and there was no significant association with NE levels. ET-1 levels were similar between the groups, but a positive correlation with systolic (P=0.04) and diastolic (P=0.03) BPs in the upright position was shown in the patient group. Increased levels of plasma NE are sustained in women with previous pre-eclampsia and may contribute to the increased risk for cardiovascular disease in these women.

• この雑音の特徴は鎖骨下、特に右側に聴取される「シャー」という連続性雑音で、臥位にすると減弱あるいは消失することである。右側に多い理由として、上大静脈と左、右無名静脈の結合部に生じやすいためと考えられている。この雑音を認めた場合も以後の検査は不要である。(参考1より引用)
