The ability of catfish to inflict extremely painful wounds with their pectoral and dorsal stings has been well known for many decades. The venom apparatus of the African catfish Clarias gariepinus (Burchell, 1822), and stinging catfish Heteropneustes fossilis (Bloch, 1794) is constituted by a single, sharp and stout sting immediately in front of the soft-rayed portion of the pectoral fins. The sting has well developed articulations, making it possible for it to become erect and locked. The toxicological centres in Poland have recorded 17 cases of envenomations caused by stinging catfish and African catfish; the injury was accompanied by intense pain, numbness of the site, dizziness, local oedema and erythema. In addition, systemic symptoms such as tachycardia, weakness and arterial hypotension were observed. The treatment of these injuries should include cleansing of the wound and surrounding area. Immersion of the wounded extremity in hot water (45 degrees C) was used for the pain control. An attempt to remove any spinal sheath or remnant must be undertaken. Antibiotic management depends on several factors: the age and immune status of the victim, the interval between injury and presentation, or the presence of a foreign body. The most serious long-term complications of sting envenomation involve infections.

Signs and symptoms associated with pheochromocytomas are predominantly caused by catecholamine excess, but tend to be highly variable and non-specific. In this study, we evaluated 23 male and 35 female pheochromocytoma patients for symptoms and signs of pheochromocytoma with special regard to gender-related differences in presentation. Total symptom score comparison between genders showed significant differences (12.0 vs. 7.8, P-value 0.0001). Female patients reported significantly more headache (80% vs. 52%), dizziness (83% vs. 39%), anxiety (85% vs. 50%), tremor (64% vs. 33%), weight change (88% vs. 43%), numbness (57% vs. 24%), and changes in energy level (89% vs. 64%). Females and males displayed comparable biochemical phenotypes (60% and 65% noradrenergic phenotype, respectively). Use of alpha- and/or beta-blockade between males and females did not differ significantly. Subgroup analyses and multiple regression analysis revealed gender differences to be irrespective of benign or malignant disease, use of adrenoceptor-blockade, age and biochemical phenotype. We conclude female patients have significantly more self-reported pheochromocytoma signs and symptoms than male patients irrespective of biochemical phenotype and tumor presentation which may be related to distinct catecholamine receptor sensitivity. Clinicians should be aware of these complaints in female pheochromocytoma patients and offer adequate treatment if indicated.

On April 8, 2009, the Los Angeles Police Department (LAPD) notified officials from the Los Angeles County Department of Public Health (DPH) in California about a group of preschool teachers with nausea, dizziness, headache, and numbness and tingling of fingertips after consumption of brownies purchased 3 days before from a sidewalk vendor. To characterize the neurologic symptoms and determine whether these symptoms were associated with ingestion of the brownies, the police and health departments launched a collaborative investigation. This report summarizes the results of that investigation, which detected cannabinoids in a recovered sample of the brownies. Two patients sought medical attention, and one patient's urine and serum tested positive for 11-nor-9-carboxy-delta 9-tetrahydrocannabinol (THC-COOH), a marijuana metabolite. The findings in this report demonstrate the utility of a collaborative investigation by public health and law enforcement.The findings also underscore the need to consider marijuana as a potential contaminant during foodborne illness investigations and the importance of identifying drug metabolites by testing of clinical specimens soon after symptom onset.

General practitioners (GPs) see many patients with various symptoms such as dizziness, general fatigue, chronic headache, numbness, chronic upper abdominal pain and chronic diarrhea and these patients often have no abnormal findings in diagnostic tests. Even some specific conditions are categorized as "diseases" such as "fibromyalgia" and "non-ulcer dyspepsia", the patients actually suffer from various illnesses and have common questions. One is "Why am I suffering from such illness?" and the other is "How can I waive from the suffering?". GPs should usually face with these patients' questions. Even without categorization by "functional somatic syndrome", GPs provide continuity of care and sometimes provide prescriptions for such patients. The concept of postmodern is essential in management of functional somatic syndrome.

The stinging catfish Heteropneustes fossilis (Bloch, 1794) has become a popular aquarium fish in Poland and is available in almost every pet shop. The toxicological centers in Cracow, Gdansk and Warsaw have recorded twelve cases of envenomations caused by stinging catfish in the years 1994-2008. In most cases the injury was accompanied by oedema, erythema, intense pain, numbness of the site and dizziness. Schema of medical management was prepared using analysis of cases.

The principal toxic ingredients of aconite roots include aconitine, mesaconitine and hypaconitine, which are known cardiotoxins and neurotoxins. A 58-year-old man took a decoction of 11 g each of processed 'chuanwu' (the main root of Aconitum carmichaeli) and processed 'caowu' (the root of A. kusnezoffii) as treatment for his neck pain. One hour later, he experienced numbness of tongue and the four limbs, generalized weakness, nausea, vomiting, diarrhoea and dizziness. Three hours after ingestion, he was admitted to hospital. His blood pressure was 106/53 mmHg and heart rate 65 beats/min. Six hours after ingestion, he became hypotensive (systolic blood pressure <100 mmHg) with bradycardia (heart rate <60 beats/min). As treatments for the hypotension, he was given intravenous infusions of 0.9% saline (125 mL/hour) for 15 hours (7-21 hours after ingestion) and dopamine (3 microg/kg/min) for 36 hours (10-45 hours after ingestion). He was given atropine 0.6 mg intravenously 7 and 24 hours after ingestion. He was hypotensive for 31 hours (6-36 hours after ingestion), with a systolic blood pressure of 84-106 mmHg (mean 93.5) and a diastolic blood pressure of 40-59 mmHg (mean 51.8). He had bradycardia for 36 hours (6-41 hours after ingestion), with a heart rate of 45-68 beats/min (mean 56.5). On discharge (48 hours after ingestion), his blood pressure was 117/82 mmHg and heart rate 70 beats/min. In patients with aconite poisoning, prolonged hypotension and sinus bradycardia may occur and supportive therapy with close monitoring of blood pressure and cardiac rhythm are essential.

Presentation of acute ST segment elevation myocardial infarction in the setting of acute subclavian artery thrombosis in a patient who underwent coronary artery bypass grafting with a left internal mammary artery graft, which is not believed to have been previously described. We report a 75-year-old woman with presentations of dizziness, nausea, left-arm numbness, and a cold left hand, who later had chest pain develop. Acute ST segment elevation myocardial infarction was diagnosed, and both a computed tomography and an angiography disclosed a thrombus extending from the proximal portion of the left subclavian artery to the orifice of the left internal mammary artery. The patient was free from the previously listed symptoms after undergoing emergent thrombectomy, with complete extraction of the long thrombus from the subclavian artery. Unfortunately, she died of pneumonia and septic shock 1 1/2 months later.

Depression is common in whiplash-associated disorders (WAD). Our objectives were to identify factors associated with depressive symptomatology occurring in the initial stages of WAD, and to identify factors predicting the course of depressive symptoms. A population-based cohort of adults sustaining traffic-related WAD was followed at 6 weeks, 3, 6, 9, and 12 months. Baseline measures (assessed a median of 11 days post-crash) included demographic and collision-related factors, prior health, and initial post-crash pain and symptoms. Depressive symptomatology was assessed at baseline and at each follow-up using the Centre for Epidemiological Studies Depression Scale (CES-D). We included only those who participated at all follow-ups (n = 3,452; 59% of eligible participants). Using logistic regression, we identified factors associated with initial (post-crash) depression. Using multinomial regression, we identified baseline factors predicting course of depression. Courses of depression were no depression; initial depression that resolves, recurs or persists, and later onset depression. Factors associated with initial depression included greater neck and low back pain severity, greater percentage of body in pain, numbness/tingling in arms/hand, dizziness, vision problems, post-crash anxiety, fracture, prior mental health problems, and poorer general health. Predictors of persistent depression included older age, greater initial neck and low back pain, post-crash dizziness, vision and hearing problems, numbness/tingling in arms/hands, anxiety, prior mental health problems, and poorer general health. Recognition of these underlying risk factors may assist health care providers to predict the course of psychological reactions and to provide effective interventions.

Subclavian steal syndrome (SSS) is caused by hypoplasia of a vertebral artery or stenosis or occlusion of the subclavian artery or the brachiocephalic artery with subsequent retrograde filling of the subclavian artery via the contralateral vertebral artery. Symptoms of SSS are due to vertbrobasilar insufficiency or ischemia of the ipsilateral upper extremity, and they may include dizziness, syncope, ataxia, arm claudication, hand numbness or a decrease in brachial blood pressure on the affected side. However, most SSS cases are asymptomatic and they are classified as subclavian steal phenomenon (SSP). Atherosclerosis is the common cause of SSS, and Takayasu arteritis, neurofibromatosis, trauma, embolization, congenital vascular anomalies and surgical interruption of the subclavian artery can be identified among the other causes. We describe a rare case of hypervascular thyroid nodule presenting with features of SSP. The patient was hospitalized with acute cerebral infarction due to middle cerebral artery (MCA) severe stenosis. The patient had conservative therapy in the acute stage, and underwent STA-MCA anastomosis for MCA stenosis in the chronic stage. SSS was asymptomatic although there was laterality in blood pressure in the patient's bilateral upper limbs. Thyroid tumor was regarded as benign by radiological findings, laboratory data, and physical examination. If SSS becomes symptomatic, removal of the thyroid tumor may be indicated.

We reported 37 patients with myelodysplastic syndromes (MDS) of refractory cytopenia with multilineage dysplasia or refractory anemia with excess blasts who were treated with cyclosporin A (CyA)/thalidomide combination therapy. Of them, 19 patients (19/37, 51.4%) achieved a hematologic improvement and erythroid response (HI-E); 9 patients (9/29, 31.0%) achieved hematologic improvement and platelet response (HI-P) and 7 patients (7/33, 21.2%) achieved hematologic improvement and neutrophil response (HI-N). 15 of 32 (46.9%) transfusion-dependent patients achieved independence from transfusion. The median response duration of HI-E, HI-P and HI-N were 88 (4-108) weeks, 78 (8-84+) weeks and 78 (10-84+) weeks, respectively. Some patients presented with I or II grade hepatic or nephritic impairment, constipation, lethargy, dizziness, edema, rash or sense of numbness. Therefore, CyA combined with thalidomide appears to be useful and is relatively well-tolerated for patients with MDS.
