The current mini-review describes the toxic effects of zinc inhalation principally in the workplace and associated complications with breathing and respiration. The International Classification of Functioning, Disability and Health Criteria were used to specifically select articles. Most of the commercial production of zinc involves the galvanizing of iron and the manufacture of brass. The recommended daily allowance for adults is 15 mg zinc/day. Metal fume fever associated with inhalation of fumes of ZnO is characterized by fatigue, chills, fever, myalgias, cough, dyspnea, leukocytosis, thirst, metallic taste and salivation. ZnCl(2) inhalation results in edema in the alveolar surface and the protein therein the lavage fluid is elevated. Particular pathological changes associated with zinc intoxication include: pale mucous membranes; jaundice; numerous Heinz bodies; and marked anemia. Adequate ambient air monitors for permissible exposure limits, excellent ventilation and extraction systems, and approved respirators are all important in providing adequate protection.

H1N1, seasonal flu, and upper respiratory infection over-the-counter (OTC) prevention recommendations seem daunting, but in reality, only several diverse lifestyle changes, supplements, and prescriptions have adequate evidence that should be discussed with patients. In addition, numerous other recommendations contain little to no evidence. For example, most heart-healthy behavioral changes, such as reducing visceral adipose tissue, simultaneously improve immune health, and this needs to be emphasized. Ethyl alcohol hand gel and plain soap and water should be encouraged, and antimicrobial soaps should be discouraged. Gargling with water and using nasal saline spray are also cost effective and supported with clinical evidence. Vitamins C and D have the largest benefit-to-risk ratio for patients and may reduce the risk of pneumonia from a recent meta-analysis. Other supplements, such has echinacea, vitamin E, and zinc, have some clinical data, but also have potential long-term safety issues. High-calorie antioxidant beverages only encourage weight and waist gain, but a teaspoon or two of honey has antimicrobial activity and may suppress cough. Finally, vaccine compliance as early as possible should be promoted as a selfless act that reduces viral transmission that could cause morbidity and mortality in the most immune vulnerable individuals, and simply promotes herd immunity, rather than a self-centered act whose individual result and response (n = 1) currently and unfortunately seems to mirror the perceived personal effectiveness or lack of effectiveness of the vaccine.

Metal fume fever (MFF) is an important occupational-related illness resulting from inhalation of volatile metal oxides, especially zinc, that are produced during welding or cutting of metal materials. Onset of MFF is rapid, occurring within a few hours after inhalation of the fumes. Symptoms include fever, chills, cough, dyspnea, headache, myalgia, and malaise. Symptoms are self-limiting and typically resolve within 24 hours with a subsequent short-lived tolerance to zinc oxide fumes that disappears after one to two days of avoidance. In this report, we present an overview of MFF's history, pathogenesis, clinical presentation, regulatory guidelines, and prevention recommendations. This review is followed by a description of MFF cases reported by the Louisiana Poison Control Center to the Louisiana Office of Public Health's Section of Environmental Epidemiology and Toxicology during a two-year period.

Porcine reproductive and respiratory syndrome virus (PRRSV) infects mainly the porcine alveolar macrophages (PAMs) and causes porcine reproductive and respiratory syndrome (PRRS). Previous studies have analyzed the global gene expression profiles of lung tissue in vivo and PAMs in vitro following infection with PRRSV, however, transcriptome-wide understanding of the interaction between highly pathogenic PRRSV (HP-PRRSV) and PAMs in vivo has not yet been established. In this study, we employed Affymetrix microarrays to investigate the gene expression patterns of PAMs isolated from Tongcheng piglets (a Chinese indigenous breed) after infection with HP-PRRSV. During the infection, Tongcheng piglets exhibited typical clinical signs, e.g. fever, asthma, coughing, anorexia, lethargy and convulsion, but displayed mild regional lung damage at 5 and 7 dpi. Microarray analysis revealed that HP-PRRSV infection has affected PAMs in expression of the important genes involved in cytoskeleton and exocytosis organization, protein degradation and folding, intracellular calcium and zinc homeostasis. Several potential antiviral strategies might be employed in PAMs, including upregulating IFN-induced genes and increasing intracellular zinc ion concentration. And inhibition of the complement system likely attenuated the lung damage during HP-PRRSV infection. Transcriptomic analysis of PAMs in vivo could lead to a better understanding of the HP-PRRSV-host interaction, and to the identification of novel antiviral therapies and genetic components of swine tolerance/susceptibility to HP-PRRS.

A 50-year-old man with a 30-year occupational history of welding presented with low-grade fever, fatigue and persistent dry cough. Computed tomography (CT) of the chest revealed interlobular septal thickening and bilateral non-segmental patchy ground-glass opacities except in the sub-pleural zone. He revealed that he had inhaled nickel fumes 3 days previously at work. These findings suggested a diagnosis of pneumonitis induced by inhalation of nickel fumes. Fewer reports describe pneumonitis associated with the inhalation of nickel compared with zinc fumes. Although nickel compounds are particularly pernicious among the transition metals and more toxic than zinc compounds, nickel fume inhalation rarely induces lethal acute respiratory distress syndrome. Our patient was successfully treated with corticosteroid.

A seven-month-old Cocker Spaniel had a cough, acute lethargy, decreased responsiveness, and episodes of hyperexcitability. There were bilateral generalized increased lung sounds, bilateral episcleral hemorrhage, and systemic hypertension. Prolonged buccal mucosal bleeding time and elevated D-dimer concentrations were detected. Radiographically, there was a generalized moderate unstructured interstitial pattern. In thoracic CT images, there was a diffuse moderate hyperattenuating appearance of the bronchial walls and interstitium and diffuse areas of moderate bronchiectasis. The brain CT images were characterized by marked hyperattenuating well-defined masses. In addition, there were smaller hyperattenuating and hypoattenuating masses scattered throughout the cerebral and cerebellar parenchyma. A zinc sulphate flotation test confirmed large numbers of Angiostrongylus vasorum L1 larvae. Despite therapy the dog continued to deteriorate and underwent euthanasia. Postmortem examination confirmed the presence of multiple intracranial and extracranial hemorrhages. Angiostrongylosis should be considered as one of the differential diagnoses in dogs presenting with neurologic signs consistent with acute intracranial haemorrhage.

Vocal process granuloma is a benign lesion that occurs on the arytenoid cartilage. It tends to recur locally, and there is a great diversity of methods to treat it. Here, we reviewed the effects of zinc sulfate therapy program in 16 patients with vocal process granulomas. Eleven patients had a history of trauma or laryngeal intubation and five patients had unknown origin. Eleven had recurrence after one to three failed surgeries, and the others had no prior treatment. Symptoms included hoarseness, sore throat, lump sensation in the throat and cough that apparently improved. The granulomas did not recur for at least 1 year. No complications occurred. For vocal process granuloma, zinc sulfate therapy is good either as an initial or compensatory treatment.

The common cold, or upper respiratory tract infection, is one of the leading reasons for physician visits. Generally caused by viruses, the common cold is treated symptomatically. Antibiotics are not effective in children or adults. In children, there is a potential for harm and no benefits with over-the-counter cough and cold medications; therefore, they should not be used in children younger than four years. Other commonly used medications, such as inhaled corticosteroids, oral prednisolone, and Echinacea, also are ineffective in children. Products that improve symptoms in children include vapor rub, zinc sulfate, Pelargonium sidoides (geranium) extract, and buckwheat honey. Prophylactic probiotics, zinc sulfate, nasal saline irrigation, and the herbal preparation Chizukit reduce the incidence of colds in children. For adults, antihistamines, intranasal corticosteroids, codeine, nasal saline irrigation, Echinacea angustifolia preparations, and steam inhalation are ineffective at relieving cold symptoms. Pseudoephedrine, phenylephrine, inhaled ipratropium, and zinc (acetate or gluconate) modestly reduce the severity and duration of symptoms for adults. Nonsteroidal anti-inflammatory drugs and some herbal preparations, including Echinacea purpurea, improve symptoms in adults. Prophylactic use of garlic may decrease the frequency of colds in adults, but has no effect on duration of symptoms. Hand hygiene reduces the spread of viruses that cause cold illnesses. Prophylactic vitamin C modestly reduces cold symptom duration in adults and children.

Despite the widespread use of over-the-counter (OTC) cough and cold medications (CCMs), the effectiveness of most CCMs has not been proven in children. A meta-analysis summarizing trials using OTC CCMs for viral-induced cough found no evidence for or against the use of OTC medicines in both paediatric and adult populations when cough frequency and severity, as well as physician assessments, were compared. Furthermore, North American data suggest that OTC CCMs may be associated with medication errors and adverse events, resulting in visits to emergency departments and even leading to death. The present article provides information on current evidence for cough and cold therapies, including fluid intake, humidified air, antihistamines, echinacea, zinc, honey and vitamin C, for caregivers of children and youth.

We conducted a survey involving 1,604 households to determine community care-seeking patterns and 163 exit interviews to determine appropriateness of treatment of common childhood illnesses at private sector drug shops in two rural districts of Uganda. Of children sick within the last 2 weeks, 496 (53.1%) children first sought treatment in the private sector versus 154 (16.5%) children first sought treatment in a government health facility. Only 15 (10.3%) febrile children treated at drug shops received appropriate treatment for malaria. Five (15.6%) children with both cough and fast breathing received amoxicillin, although no children received treatment for 5-7 days. Similarly, only 8 (14.3%) children with diarrhea received oral rehydration salts, but none received zinc tablets. Management of common childhood illness at private sector drug shops in rural Uganda is largely inappropriate. There is urgent need to improve the standard of care at drug shops for common childhood illness through public-private partnerships.
