A 44-year-old patient died from amyotrophic lateral sclerosis (ALS) after nine years of heavy exposure to cadmium (Cd) in a nickel cadmium (Ni-Cd) battery factory. Two years after starting work he and co-workers had experienced pruritus, loss of smell, nasal congestion, nosebleeds, cough, shortness of breath, severe headaches, bone pain, and proteinuria. Upper back pain and muscle weakness progressed to flaccid paralysis. EMG findings were consistent with motor neuron disease. Cd impairs the blood-brain barrier, reduces levels of brain copper-zinc (Cu-Zn) superoxide dismutase (SOD), and enhances excitoxicity of glutamate via up-regulation of glutamate dehydrogenase and down-regulation of glutamate uptake in glial cells. High levels of methallothionein, a sign of exposure to heavy metals, have been found in brain tissue of deceased ALS patients. The effects of Cd on enzyme systems that mediate neurotoxicity and motor neuron disease suggest a cause effect relationship between Cd and ALS in this worker.

A 40-year-old Caucasian man diagnosed with right deep venous thrombosis secondary to trauma was treated with subcutaneous enoxaparin. Within minutes of administering the first dose (1 mg/kg), he experienced an apparent anaphylactoid reaction; symptoms were abdominal pruritus, severe cough, shortness of breath, anxiety, and global pruritus. Physical examination revealed an erythematous macular rash and stridor on auscultation secondary to cervical edema. No other drugs were given before the reaction occurred, and the patient's only drug therapy at home had consisted of a daily multivitamin, and acetaminophen and ibuprofen as needed. Administration of low-molecular-weight heparins such as enoxaparin is increasing, and clinicians must be aware of the potential for adverse drug events such as hypersensitivity reactions.

At present, no universally-accepted effective treatment for cutaneous gnathostomiasis is available. At the Hospital for Tropical Diseases, Mahidol University, albendazole 400 mg twice a day for 14 days is commonly prescribed for patients diagnosed with cutaneous gnathostomiasis. The efficacy of albendazole to induce outward migration of the parasite was less than or around 20% in 2 studies. Research for alternative, more efficacious treatment, is needed. In this prospective open-labeled study, we assessed the safety of ivermectin in 20 Thai patients diagnosed with cutaneous gnathostomiasis. Ivermectin, one time only, at dosages of 50, 100, 150, or 200 microg/kg bodyweight, was given orally to 4 groups of patients, 5 patients each group. Adverse events were recorded and laboratory tests were obtained before and after treatment. No serious adverse events occurred in this study. Forty adverse events were possibly related to ivermectin. The adverse events were malaise (35%), myalgia (30%), drowsiness (30%), pruritus (20%), nausea/vomiting (20%), dizziness (15%), diarrhea (15%), feeling of shortness of breath (10%), feeling of palpitations (10%), constipation (5%), anorexia (5%), and headache (5%). These adverse events were self-limited and not dose-related. Laboratory abnormalities were found in 3 patients (15%). Transient microscopic hematuria, pyuria, and mildly elevated liver enzymes were found in 1 patient each. Ivermectin single dose, of 50,100, 150, and 200 microg/kg bodyweight, is considered safe in Thai patients. Future trials of ivermectin on human gnathostomiasis may be performed using dosages up to 200 microg/kg bodyweight.

A 52-year-old black woman presented with a 2-day history of lower lip swelling 5 days after starting a new medication, lisinopril. She had never experienced similar episodes in the past. She denied shortness of breath, tightening of the throat, swelling of the tongue, generalized cutaneous eruption, urticaria, or pruritus. She also denied symptoms consistent with facial paresis. Her past medical history was significant for hepatitis C infection, coronary artery disease, and hypertriglyceridemia. She had a 15 pack-year smoking history and denied both alcohol and drug abuse. She had never received a blood transfusion and was HIV negative. Physical examination disclosed a tender, swollen, and erythematous lower lip with induration, oozing, and crusting (Figure 1). Pinpoint openings evident throughout the lip surface exuded a clear, sticky, mucoid secretion. Tongue, parotid glands, and regional lymph nodes were normal. The working diagnosis was angioedema secondary to lisinopril. The presumptive offending drug was discontinued, and conservative therapy (topical clobetasol ointment, oral ranitidine, and oral fexofenadine) was initiated. Despite treatment, signs and symptoms persisted unabated. One week after initial presentation, a punch biopsy of her lower lip was taken to rule out granulomatous cheilitis and sarcoidosis. Histopathology included diffuse lymphohistiocytic infiltrate, minimal microabscess formation, and notable absence of granulomata. There was neither hypertrophy nor detectable abnormality of the salivary glands, with the exception of infiltrating mononuclear cells. Based on the clinical history and compatible pathologic findings, a diagnosis of cheilitis glandularis was made. Specifically, crusting and erosion clinically suggested a diagnosis of the superficial suppurative subtype of cheilitis glandularis. The patient received oral penicillin (dicloxacillin, 1.0 g/d) combined with oral fluoroquinolone (ciprofloxacin, 1.0 g/d). Within 2 weeks of starting the antibiotics, the lip swelling significantly decreased (Figure 2) and the patient was left with a mildly indurated nodule at the labial commissure. Following a 4-week course of continued antibiotic treatment, the lip returned to near baseline state. At both 6-month and 1-year follow-up visits, the lip remained normal.

To assess the associations between job stress and somatic symptoms and to investigate the effect of individual coping on these associations. In July 2006, a cross-sectional study was conducted during a periodic health check-up of 185 Japanese male office workers (21-66 yr old) at a Japanese company. Job stress was measured by job demand, control, and strain (=job demand/control) based on the Job Content Questionnaire (JCQ). Major somatic symptoms studied were headache, dizziness, shoulder stiffness, back pain, shortness of breath, abdominal pain, general fatigue, sleep disturbance, and skin itching. Five kinds of coping were measured using the Job Stress Scale: active coping, escape, support seeking, reconciliation, and emotional suppression. Comorbidities of hypertension, diabetes, obesity, depression, and anxiety were also evaluated. The most frequently cited somatic symptom was general fatigue (66%), followed by shoulder stiffness (63%) and sleep disturbance (53%). Of the five kinds of coping, only "active coping" was significantly and negatively associated with the number of somatic symptoms. The generalized linear models showed that the number of somatic symptoms increased as job strain index (p=0.001) and job demand (p=0.001) became higher, and decreased as active coping (p=0.018) increased, after adjusting for age and comorbidities. There was no statistical interaction among active coping, the number of somatic symptoms, and the three JCQ scales. Reporting somatic symptoms may be a simple indicator of job stress, and active coping could be used to alleviate somatization induced by job stress.

The aim of the study is to evaluate the prevalence of respiratory and skin symptoms among bakers in the district of Verona by means of two standardized questionnaires, a clinical one administered to the bakeries employees, either directly exposed to flour dust or not exposed, and one concerning the characteristics of the bakery environment. The study involved 613 bakery workers, 401 bakers and 212 sales personnel employed in 152 bakeries. Bakers exposed to flour dust reported nasal symptoms in 29.2% of cases, ocular symptoms in 13.2%, cough, shortness of breath, chest tightness, wheezing respectively in 8.7%, 7%, 4.5% 6.2% of cases, itch and skin burning with paleness respectively in 9.7% and 8.5%. A significantly lower prevalence of these symptoms, except skin paleness, was reported among the sales personnel. In bakers, a significant correlation was found between ocular-nasal and respiratory symptoms and family or self-reported history of atopy (p = 0.001). Reported flour dust air pollution at the workplace correlated with occupational ocular-nasal and respiratory symptoms (p = 0.001). Flour dust on skin and clothes correlated with crusts and excoriations (p = 0.01). Our study confirms the high prevalence of allergic symptoms among bakers and the need of clinical assessment.

Mast cell tryptase can be an indicator of type I hypersensitivity reaction and thus may serve as a surrogate marker of anaphylaxis. A 34-year-old white male patient presented with a history of systemic lupus erythematosus. Shortly after administration of cefazolin for dialysis, he developed pruritus and shortness of breath. He expired an hour later. Autopsy excluded anatomic causes of death. There was an elevated postmortem mast cell tryptase level, 29.2 ng/mL. For mast cell tryptase level to be useful, the patient must survive long enough after exposure to an allergen for mast cells to release this enzyme. A credible allergen must be identified. In this case such, mast cell tryptase could establish anaphylaxis as the cause of death. The case suggests that in a patient with autoimmune disease, it may be prudent to test for immune reaction to a drug before administering it a second time via pinprick or other method.

Exercise-induced anaphylaxis (EIA) is a syndrome in which patients experience the symptoms of anaphylaxis, which occur only after increased physical activity. It is characterised by a gradual development of symptoms: itching, erythema, urticaria, angioedema, anaphylactic shock (hypotension, syncope, loss of consciousness, shortness of breath, wheezing, nausea and vomiting), and at the end of the late phase prolonged urticaria and headache. The triggering factors for EIA are as follows: significant exposure to airborne allergens, insect sting, weather extremes, higher air humidity, taking nonsteroidal anti-inflammatory drugs. The most frequent causative nutritive allergens include wheat, crabs and shells. Prophylactic management for EIA comprises avoding the triggers. Exercise or other physical activity should be performed in proximity of medically trained companion.

A 50-year-old man presented with initial complaints of diffuse skin pain and pruritus. Physical examination revealed scattered skin plaques and subcutaneous nodules with mild tenderness throughout the body. Skin biopsy demonstrated noncaseating epithelioid granulomas. Patient soon developed cough, fever with hot flashes, and shortness of breath on exertion. FDG PET/CT demonstrated diffuse cutaneous involvement throughout the body. Follow-up FDG PET/CT after treatment revealed a decrease in FDG uptake suggesting a good response to therapy.
