Vanadium is a steel-grey, corrosion-resistant metal, which exists in oxidation states ranging from -1 to +5. Metallic vanadium does not occur in nature, and the most common valence states are +3, +4, and +5. The pentavalent form (VO3-) predominates in extracellular body fluids whereas the quadrivalent form (VO+2) is the most common intracellular form. Because of its hardness and its ability to form alloys, vanadium (i.e., ferrovanadium) is a common component of hard steel alloys used in machines and tools. Although most foods contain low concentrations of vanadium (< 1 ng/g), food is the major source of exposure to vanadium for the general population. High air concentrations of vanadium occur in the occupation setting during boiler-cleaning operations as a result of the presence of vanadium oxides in the dust. The lungs absorb soluble vanadium compounds (V2O5) well, but the absorption of vanadium salts from the gastrointestinal tract is poor. The excretion of vanadium by the kidneys is rapid with a biological half-life of 20-40 hours in the urine. Vanadium is probably an essential trace element, but a vanadium-deficiency disease has not been identified in humans. The estimated daily intake of the US population ranges from 10-60 micrograms V. Vanadyl sulfate is a common supplement used to enhance weight training in athletes at doses up to 60 mg/d. In vitro and animal studies indicate that vanadate and other vanadium compounds increase glucose transport activity and improve glucose metabolism. In general, the toxicity of vanadium compounds is low. Pentavalent compounds are the most toxic and the toxicity of vanadium compounds usually increases as the valence increases. Most of the toxic effects of vanadium compounds result from local irritation of the eyes and upper respiratory tract rather than systemic toxicity. The only clearly documented effect of exposure to vanadium dust is upper respiratory tract irritation characterized by rhinitis, wheezing, nasal hemorrhage, conjunctivitis, cough,
sore throat
, and
chest pain
. Case studies have described the onset of asthma after heavy exposure to vanadium compounds, but clinical studies to date have not detected an increased prevalence of asthma in workers exposed to vanadium.

There are three clinical presentations of anthrax in humans: cutaneous (>95% of cases), orogastric and inhalational. The infectious form, the spore, enters the body and is thought to germinate within macrophages either at the site of inoculation (cutaneous or orogastric) or in the regional lymph node (inhalational). The bacillus then synthesizes its antiphagocytic capsule and the lethal and oedema toxins which interfere with the non-specific host defences leading to the characteristic locally destructive lesion and spread by lymphatics to the systemic circulation and other organs. The cutaneous form begins as a papule which progresses over several days to a vesicle and then ulcerates. There is often oedema, sometimes massive, probably due to the oedema toxin that surrounds the lesions which then develop a characteristic black eschar. The patient may be febrile with mild to severe systemic symptoms of malaise, headache and toxicity. Oropharyngeal anthrax presents with severe
sore throat
or an ulcer in the oropharyngeal cavity associated with neck swelling, fever, toxicity and dysphagia. Gastrointestinal anthrax begins with anorexia, nausea, vomiting and abdominal pain which may be similar to an acute abdomen. There may be diarrhoea and ascites, both of which may be haemorrhagic. Inhalational anthrax begins with non-specific symptoms of malaise, fever, myalgia and non-productive cough. After a period of 2-3 days, this is followed by a sudden onset of severe respiratory distress associated with diaphoresis, cyanosis and increased
chest pain
. There may be a widened mediastinum and pleural effusions on chest X-ray. Death follows in 24-36 h from respiratory failure, sepsis and shock. The diagnosis of anthrax is easy if it is considered. The organism is readily observed by Gram or Wright stain in local lesions or blood smear and can be easily cultured from the blood and other body fluids. However, because of its rarity, it is not often included in the differential diagnosis and in inhalational disease the diagnosis is rarely made until the patient is moribund. More rapid diagnostic tests are under development. Penicillin, combined with supportive care, remains the mainstay of treatment, although the organism is susceptible in vitro to many antibiotics. In recent years, there have been significant advances in our knowledge of the organism and its toxins and it is anticipated that similar progress will be made in the future in developing more rapid diagnostic tests and new modalities of treatment.

One hundred and sixty eight febrile adult outpatients were investigated at St Francis Designated District Hospital in fakara, a holoendemic area in Tanzania. We wanted to assess the potential anamnestic and clinical risk indicators for malaria and to establish a rational strategy for malaria management. Blood slide investigations showed that 14% of all patients were positive for P. falciparum. All the positive cases were found during the rainy season. No reliable criteria for malaria were found in the history taking and physical examinations. Signs and symptoms of respiratory tract infection such as difficulties during breathing,
sore throat
,
chest pain
, cough, pathological findings in lung auscultation and combinations of these were negatively associated with malaria parasitaemia. The same was true for lymph node swelling and a clinical diagnosis other than malaria. Quality control of blood slide results from the hospital revealed a sensitivity of 55%, a specificity of 72%, and positive and negative predictive values of 24% and 91%. The main recommendations for malaria management in adults were to improve the quality of blood slide examinations and to use a different diagnostic strategy during the dry and rainy seasons. During the dry season blood slides of febrile adult patients should only be performed if there is a suspicion of malaria and antimalarial drugs should only be administered if blood slide results are positive. During the rainy season all febrile adults without obvious cause of fever other than malaria should be treated with antimalarials without previous blood slide examination.

Pneumomediastinum in children is diagnosed in two circumstances: cervical subcutaneous emphysema or radiological findings. The predominant symptoms are dyspnoea, stabbing
chest pain
,
sore throat
and dysphagia. Traumatic injuries and pulmonary diseases such as asthma are the most common causes of pneumomediastinum. It may rarely result from iatrogenic manoeuvres or acidocetosis. Spontaneous mediastinal emphysema is seldom reported in children. Chest X-ray films are essential investigations. The treatment is directed towards the underlying cause, with conservative management being sufficient in most cases. However, the risk of surveying of pneumothorax or tension pneumomediastinum justifies close clinical follow-up in a specialised care unit. The onset of these pathologies necessitates a more aggressive therapy by aspiration through percutaneous catheter placed in the mediastinum.

Today, rheumatic fever is the most common cause of heart disease in children and young adults, and it accounts for about half of all cardiovascular diseases causing death in the first four decades of life, in India. In the present study, conducted during 1991-1992 at Chennai, India, a total of 666 school girls aged 5-15 years were examined clinically for one or more of the following signs and symptoms: repeated
sore throat
, joint pain/swelling, epistaxis,
chest pain
, breathlessness, palpitation, abdominal pains, etc. Out of the 666 children screened, 124 were recruited for the present study, based on their meeting one or more of the above mentioned clinical criteria. They were screened for the presence of group A beta-hemolytic streptococci, and for antistreptolysin O and C-reactive protein. Thus, the aim of the present study was to reduce the load of streptococcal infection and the consequent risk of developing rheumatic fever and rheumatic heart disease. In the present study group, 89.5% of the children indicated a history of repeated
sore throat
. However, only 4.0% of the children in the study group were positive for group A beta-hemolytic streptococci. The antistreptolysin O and C-reactive protein levels were higher in 11- to 15-year-old patients than in 5- to 10-year-old patients in the study group.

Gastroesophageal reflux disease can result in such supraesophageal complications as hoarseness,
sore throat
, cough, bronchitis, asthma, recurrent pneumonia, intermittent choking,
chest pain
, and ear pain. Appropriate patient care involves careful evaluation to decide on medical or surgical therapy. Preoperative testing must include endoscopy, 24-hour esophageal pH monitoring, and esophageal manometry. Additional evaluations, such as barium swallow, chest x-ray, bronchoscopy, and sinus radiographs, may be required. Medical treatment improves gastroesophageal reflux and supraesophageal symptoms. However, surgical therapy seems to provide better long-term results. A profile that predicts the best response to medical therapy has not been identified, although the best results with surgery are achieved in patients with nocturnal asthma, onset of reflux before pulmonary symptoms, laryngeal inflammation, and a good response to medical treatment.

In 568 cases suffering from upper-respiratory tract infection with
sore throat
and more than one of following clinical manifestations: arrhythmia, heart failure and
chest pain
or oppressive sensation over the chest(Group A), and another 108 cases without above clinical manifestations(Group B), myocardial perfusion imaging with 99mTc-MIBI SPECT was studied. The results revealed that the imaging in 404 cases (71.12%) of Group A supported diagnosis of myocarditis, but only 6 cases(5.56%) did so in Group B. Because of lacking the clinical manifestations of myocarditis but positive finding of CVB-IgM antibody was detected in their sera, we considered that the positive SPECT imaging in these six cases of Group B belonged to myocardial reaction due to virus infection. It was possible that some of them were suffering from subclinical type of myocarditis.

In general terms, all patients who undergo a laparoscopic fundoplication procedure should have objective evidence of gastroesophageal reflux. However, occasionally patients without objective evidence of reflux disease are referred for surgery. This study assessed the outcome of a highly selected group of patients who underwent laparoscopic fundoplication without objective evidence of reflux at either preoperative endoscopy or pH monitoring. Data from all patients undergoing laparoscopic fundoplication in our department over a 9-year period from December 1991 to January 2001 were collected prospectively. From a total of 1,003 patients, a subgroup of 15 patients was identified who had no evidence of ulcerative oesophagitis at endoscopy or abnormal reflux on 24-h pH monitoring. Eight of these patients had typical symptoms of reflux (four had predominantly heartburn, four had predominantly volume regurgitation) and seven patients had atypical symptoms such as cough, bloating,
chest pain
, or
sore throat
. All patients had tried medication for acid suppression before surgery, with five gaining little or no benefit. The mean acid exposure time was 2% (range 0.1-3.6%). A correlation between typical symptoms and reflux events of over 50% was noted in three patients. All patients underwent laparoscopic fundoplication, with one conversion to an open procedure. Mean patient satisfaction score (0-10 linear score) was 8.7 at 3 months and 1 year postoperatively. Three patients failed to improve following surgery. These three all had atypical symptoms, a symptom correlation of less than 50% with acid reflux on pH monitoring, and two of the three had a poor response to medication. All other patients benefited symptomatically from surgery. We concluded that the absence of objective evidence of reflux should not always preclude patients from a laparoscopic fundoplication. Carefully selected patients with typical reflux symptoms can have a good outcome. However, patients who do not have typical symptoms and who respond poorly to acid suppression are not likely to benefit from surgery.

Since the 1960's, CS has become the main riot control agent in use by police and army forces throughout the world. The first post-exposure symptom is a burning sensation in the eyes, nose and throat. At a later stage, lacrimation, rhinorrhea, conjunctivitis,
sore throat
and salivation appear. These symptoms are followed by
chest pain
and dry cough, and if the substance is swallowed, it may cause nausea and vomiting. This article reviews the physical properties of CS, the main dispersing techniques, the clinical signs and symptoms of exposure, including information on mutagenicity, carcinogenesis, pregnancy safety, and will introduce guidelines for treatment after exposure.
