An increasing body of evidence shows the occurrence of asthma epidemics, sometimes also severe, during thunderstorms in the pollen season in various geographical zones. The main hypothesis explaining association between thunderstorms and asthma claims that thunderstorms can concentrate pollen grains at ground level; these grains may then release allergenic particles of respirable size in the atmosphere after their rupture by osmotic shock. During the first 20-30 minutes of a thunderstorm, patients suffering from pollen allergy may inhale a high concentration of the allergenic material dispersed into the atmosphere, which can, in turn, induce asthmatic reactions, often severe...

REVIEW
Shams Y-Hassan, Per Tornvall
Takotsubo syndrome is a recently recognized acute cardiac disease entity with a clinical presentation resembling that of an acute coronary syndrome. The typical takotsubo syndrome patient has a unique circumferential left (bi-) ventricular contraction abnormality profile that extends beyond a coronary artery supply territory and appears to follow the anatomical cardiac sympathetic innervation. The syndrome predominantly affects postmenopausal women and is often preceded by emotional or physical stress. Patients with predisposing factors such as malignancy and other chronic comorbidities are more prone to suffer from takotsubo syndrome...

76 year old female presented following an episode of collapse. She was hypotensive with the paramedics and remained refractory despite fluid resuscitation. Her initial baseline tests revealed an elevated troponin; she subsequently underwent a coronary angiogram which showed mild coronary artery disease. Left ventriculogram was performed which showed abnormal mid-wall ballooning and severely impaired systolic function, characteristic of takotsubo syndrome. Echocardiogram confirmed presence of diagnosis and presence of left ventricular outflow tract obstruction with high gradient...

A 9 mo old female intact English mastiff (case 1) presented for anorexia and vomiting for 7 days. A 7 mo old male castrated American bulldog (case 2) presented for vomiting and anorexia for 2 days without diarrhea. Both dogs were diagnosed with mesenteric volvulus based on exploratory laparotomy, which also revealed an intestinal foreign body obstruction. Case 1 required critical care support during recovery but was ultimately discharged, whereas case 2 had an uncomplicated recovery. Both were reported to be back to normal 1 wk after surgery...

BACKGROUND: During scuba diving, nitrogen dissolves into the body tissues due to elevated pressure under water. During a sudden drop in pressure due to a rapid return to the water surface, arterial gas embolism can arise from pulmonary barotrauma. In a later phase, nitrogen bubbles can also arise in the venous circulation (decompression sickness). Arterial bubbles can incur vascular damage, obstruction, hypoxia and infarction. CASE DESCRIPTION: A 53-year-old healthy sport diver presented at the emergency department in a hypovolemic shock with progressive paresis of all the extremities...

BACKGROUND: An increasing number of case reports suggest that acquired renal Fanconi syndrome may be associated with prolonged use of adefovir against hepatitis B virus. Renal Fanconi syndrome is an uncommon disease, and its complication with nephrolithiasis is quite rare. Herein, we report a rare coexistence of nephrolithiasis and acquired renal Fanconi syndrome in a chronic hepatitis B-positive patient with prolonged adefovir therapy. CASE PRESENTATION: The patient presented with osteomalacia and nephrolithiasis...

BACKGROUND: Transpulmonary thermodilution is recommended in the treatment of critically ill patients presenting with complex shock. However, so far it has not been validated in hemodynamically stable patients with heart disease. METHODS: We assessed the validity of cardiac output, global end-diastolic volume index (GEDVI), an established marker of preload thought to reflect the volume of all four heart chambers, global ejection fraction (GEF) and cardiac function index (CFI) as variables of cardiac function, and extravascular lung water index (EVLWI) as indicator of pulmonary edema in 29 patients undergoing elective left and right heart catheterization including left ventricular angiography with stable coronary heart disease and normal cardiac function (controls, n = 11), moderate-to-severe aortic valve stenosis (AS, n = 10), or dilated cardiomyopathy (DCM, n = 8)...

Stress cardiomyopathy or Tako Tsubo cardiomyopathy is a cardiac pathology evoking acute coronary syndrome characterized by electrocardiographic signs, cardiac enzyme elevation and no obstructive coronary lesions. It generally affects postmenopausal women and it usually occurs after periods of intense stress. Disease onset is widely variable, ranging from anginal pain (most common) to cardiogenic shock. Exact pathophysiological mechanism continues to be debated. Various hypotheses have been posited. Abrupt elevation of adrenaline levels appears to be the most credible...

Upper urinary tract calculi with infection is a quite difficult acute urologic emergency. And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation. Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk. But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying...

Anaphylaxis is a systemic, life-threatening disorder triggered by mediators released by mast cells and basophils activated via allergic (IgE-mediated) or nonallergic (non-IgE-mediated) mechanisms. It is a rapidly evolving, multisystem process involving the integumentary, pulmonary, gastrointestinal, and cardiovascular systems. Anaphylaxis and angioedema are serious disorders that can lead to fatal airway obstruction and culminate in cardiorespiratory arrest, resulting in hypoxemia and/or shock. Often, these disorders can be appropriately managed in an outpatient setting; however, these conditions can be severe enough to warrant evaluation of the patient in the ED and in some cases, hospitalization, and management in an ICU...

Valve thrombosis can occur in mechanical prosthetic valves and is increasingly recognised in transcatheter and surgically implanted bioprosthetic valves. The risk of thrombosis of mechanical valves is higher in the mitral position compared with aortic position and in older generation valves (ball and cage valves). There is a wide spectrum of presentation from the asymptomatic patient to those with embolic complications or cardiogenic shock. A combination of transthoracic and transesophageal echocardiography is required to assess the haemodynamic effect of thrombosis (valve gradients and area), leaflet motion and thrombus size...

Extranodal natural killer T-cell lymphoma, nasal type (ENKL), formerly called lethal midline granuloma or angiocentric T-cell lymphoma, is a predominantly extranodal non-Hodgkin lymphoma characterized by vascular damage, necrosis, and an association with Epstein-Barr virus. In the United States, it is more frequently seen in Asian, Asian Pacific Islander, and Hispanic descent populations and is more prevalent in males in their fifth decade. Clinical presentation of NK nasal lymphoma most commonly involves epistaxis; obstruction; discharge; destructive mass in sinuses, palate, and nose; and skin ulceration...

Abdominal pain is the foremost complication of chronic pancreatitis (CP). Pain can be related to recurrent or chronic inflammation, local complications or neurogenic mechanisms with corresponding changes in the nervous systems. Both pain intensity and the frequency of pain attacks have been shown to reduce quality of life in patients with CP. Assessment of pain follows the guidelines for other types of chronic pain, where the multidimensional nature of symptom presentation is taken into consideration. Quantitative sensory testing may be used to characterize pain, but is currently used in a research setting in advanced laboratories...

Cardiomyopathy is a progressive disease of myocardium causing either mechanical or electrical disturbances. Sepsis-induced cardiomyopathy (SICM) is an entity of cardiomyopathy which is reversible in 1â€"2 weeks after recovery from sepsis or septic shock. SICM is thought to have unpredictable cumulative mortality towards sepsis but its exact mechanism remains elusive. We report a case of Escherichia coli SICM in a 63-year-old woman presented with sudden onset of dyspnoea on exertion and orthopnoea following nausea, vomiting and diarrhoea after consuming Chinese foods...

BACKGROUND: Mechanical stress is a key pathogenic driver of apoptosis in the tubular epithelium in obstructive nephropathy. Heat shock protein 70 (Hsp70) and Wilms' tumor (WT-1) have been proposed to represent linked downstream effectors of the cytoprotective properties of NO. In the present study, we sought to evaluate whether the cytoprotective effects of L-arginine in neonatal obstructive nephropathy may be associated with NO-dependent increases in WT-1 and Hsp70 expression. METHODS: Neonatal Wistar-Kyoto rats were submitted to complete unilateral ureteral obstruction (UUO) and treated thereafter with vehicle, L-NAME or L-arginine by daily gavage for 14 days to block or augment NO levels, respectively...

BACKGROUND: Multiple lymphomatous polyposis is a rare type of gastrointestinal lymphoma that extensively infiltrates the intestine. Multiple lymphomatous polyposis originates from the mantle zone of the lymphoma follicle and is considered to be a mantle cell lymphoma, which is a relatively aggressive type of B-cell non-Hodgkin's lymphoma. We report an unusual case of a patient with multiple lymphomatous polyposis with extensive colorectal involvement and acute intestinal obstruction, an atypical complication of this rare disease...
