Non invasive ventilation refers to the technique of providing ventilatory support without a direct conduit to the airway. It is a promising new technique, which is particularly useful in patients with COPD. Patients with COPD are prone to develop acute exacerbations, which pushes them into acute respiratory failure. Under these circumstances, tracheal intubation and mechanical ventilation is associated with significant morbidity and mortality. A number of well conducted studies support the fact that non invasive positive pressure ventilation (NIPPV) in these circumstances reduces rates of intubation, mortality, complications and duration of hospital stay. The biggest advantage of these techniques is their simplicity, ease of implementation and improved patient comfort allowing them to retain important functions like speech, cough and swallowing. NIPPV should be instituted early in the course of acute respiratory failure due to COPD before irreversible fatigue sets in. The current thinking is that NIPPV rests the respiratory muscles allowing other therapies time to be effective. Facilities for NIPPV should be available in all hospitals admitting patients with respiratory failure. Patients with severe, stable COPD who are hypercapnic and are deteriorating despite maximal conventional treatment should definitely be offered a trial of NIPPV. In such patients NIPPV has been shown to improve quality of life, reverse blood gas abnormalities, improve exercise tolerance and reduce hospital admissions. Physicians must familiarize themselves with this promising new ventilatory technique.

An 84-year-old man was referred to our hospital because of fever, cough, and hemoptysis. The patient had acute respiratory failure (PaO2 < 40 mmHg) on admission, with diffuse interstitial infiltration and bilateral pleural effusion. The bronchoalveolar lavage fluid was bloody, and contained a high percentage of eosinophils (32%). A diagnosis of acute eosinophilic pneumonia was established, and the patient made a rapid recovery after corticosteroids were administered. When the DLST (drug lymphocyte stimulation test) was performed after the corticosteroid therapy was stopped, it was positive for serrapeptase, which had been prescribed for chronic cystitis for 3 months before the onset of the pneumonia. This was a case of drug (serrapeptase)-induced pneumonitis manifesting as acute eosinophilic pneumonia.

The aim of this paper is to review the indications for use by physiotherapists, such as physiological rationale and the comparative efficacy of intermittent positive pressure breathing (IPPB) and continuous positive airway pressure (CPAP). A brief discussion of nasal intermittent positive airway pressure is also included. The use of IPPB for post operative prophylaxis has not been supported in the literature. In patients with low lung volumes resulting from neuromuscular disease or spinal injury, IPPB may be useful in the acute phase to improve tidal volume and cough effectiveness. The physiological benefits of CPAP to improve lung volumes are well documented in the literature. Physiotherapists use CPAP as an intermittent application in patients with low lung volumes following surgery. It is predominantly used as a second line intervention in the presence of refractory atelectasis and poor gas exchange. It may also be indicated in other patient groups with similar physiological problems. Nasal intermittent positive airway pressure combines the beneficial effects of intermittent positive pressure breathing and continuous positive airway pressure. There have been many studies evaluating its effectiveness. These have been supportive for patients with neuromuscular disease and sleep disordered breathing, but more research is needed in patients with acute respiratory failure.

A 67-year-old man with a four-year history of mixed connective tissue disease (MCTD) associated with interstitial pneumonia was admitted to our hospital with a complaint of dyspnea and moist cough. Because the interstitial pneumonia was exacerbated, he was given high-dose steroid treatment (pulse therapy and sequential oral treatment of PSL 50 mg/day). After treatment his general condition showed some improvement, but then he suddenly died of acute respiratory failure. Autopsy disclosed fat emboli in the lungs, kidneys, liver and myocardium. The fat embolism may have been a consequence of the steroid treatment. Fat embolism should be taken into account as one of the causes of the acute respiratory failure in collagen vascular disease patients receiving steroid treatment.

Although most instances of sore throat are caused by relatively benign infectious or noninfectious processes, pharyngitis may herald serious or even fatal illnesses. Viral pharyngitis is the diagnosis in most cases, but because GABHS is the most common bacterial organism requiring antimicrobial treatment, an office visit is often necessary. There is no exact constellation of signs and symptoms that is pathognomonic for GABHS; nevertheless, sudden onset of sore throat with fever and cervical lymph node tenderness, in the absence of cough and nasal symptoms, is at least suggestive in adults, and possibly in children. Physical examination and prudent use of laboratory testing will assist in the diagnosis of both acute and chronic pharyngitis. The primary care provider who promptly identifies and properly treats patients infected with S. pyogenes has reduced the number of missed school or work days, the risk of developing ARF, the likelihood of transmission to others, and inappropriate use of antibiotics for those with other causes of sore throat. Further education of patient, family, and other clinicians will reduce medical expenses, avoid unnecessary antibiotic exposure, and inform the public regarding judicious management of pharyngitis.

Leptospirosis may have important complications, such as acute respiratory failure (ARF) associated or not with other organic dysfunction, with a high mortality rate. We report the characteristics and evolution of severe leptospirosis associated with ARF. During 10 years, 35 consecutive adult patients admitted in two general Intensive Care Units with severe leptospirosis and ARF, were followed up. Clinical characteristics, associated organic dysfunction and mortality were analyzed. Survivors were compared with non-survivors. The most frequent clinical manifestations were dyspnea, fever, myalgia, jaundice, hemoptysis and coughing. All patients presented ARF, needing mechanical ventilation, as well as other organic dysfunctions. The mortality rate was 51%. Non-survivors were older and had a higher incidence of organic dysfunction, mainly renal, cardiovascular and neurological failures, as well as a higher level of acidosis. In conclusion, leptospirosis should be considered as a cause of severe ARF and other associated organic dysfunctions.

Noninvasive ventilation (NIV), i.e. without tracheal intubation, has been reintroduced for the treatment of respiratory failure to reduce the complications of mechanical ventilation. Nowadays, NIV with positive pressure is the preferred method, applied through a mask held in place by a harness. Several masks can be used (nasal, bucconasal facial) and a variety of means can be used to keep them in place. Many respirators can be selected, ranging from those traditionally used in the intensive care unit(ICU) to specific NV respirators and conventional ICU respirators with specific software for NIV. Many respiratory modalities can be used according to the respirator (biphasic positive airway pressure [BIPAP], proportional assist ventilation, pressure support, synchronized intermittent mandatory ventilation [SIMV], etc.). NIV is mainly indicated in exacerbations of chronic respiratory failure: neuromuscular diseases, pretransplantation cystic fibrosis, and obstructive sleep apnea syndrome. It is also indicated in acute respiratory failure: pneumonia, status asthmaticus, and acute lung edema. The main contraindications are a weakened airway protection reflex(absent cough reflex) and hemodynamic instabiity. The advantages of NIV derive mainly from avoiding the complications associated with invasive ventilation. NIV also presents some disadvantages, especially the greater workload involved to ensure good patient adaptation to the respirator. The most common sequelae of NIV are skin lesions due to pressure on the nasal bridge.

Virus-associated hemophagocytic syndrome (VAHS) triggered by HHV-8 is extremely rare and has been reported only in 9 immunocompromised patients. We report the first case of HHV-8-associated VAHS in an HIV-negative, immunocompetent patient with plasmablastic variant (plasmablastic microlymphoma) of multicentric Castleman disease (MCD). This 61-year-old man presented with fever, cough, and bilateral inguinal lymphadenopathy. Biopsy of the right inguinal lymph node revealed plasmablastic MCD with nodular aggregates of plasmablasts expressing IgM, MUM1, HHV-8 latency-associated nuclear antigen, and viral interleukin-6. These plasmablasts were monotypic for Iglambda light chain expression but not Igkappa. All the B-cell clonality assays, including IgH-FR2, IgH-FR3, DH-JH, Igkappa, and Iglambda PCR, showed a polyclonal pattern. His serum human interleukin-6 level was markedly elevated and was negative for EBV acute infection/reactivation. The marrow aspirate showed florid hemophagocytosis. His disease progressed rapidly to multisystemic illness, and he died of acute respiratory failure in 1 month. Our case showed that HHV-8 might trigger VAHS in an immunocompetent patient with plasmablastic MCD. We speculated that our patient developed VAHS under the cytokine storm associated with the proliferating HHV-8-infected plasmablasts, similar to the EBV-triggered VAHS in patients with EBV-associated T-cell lymphoma.

Diffuse pulmonary hemorrhage leading to death is a syndrome which may develop in leptospirosis, but its pathophysiology is not well documented. We report an autopsy case of leptospirosis. A healthy 41-year-old man presented with low back myalgia, dry cough and fever for 4 days and a normal chest X-ray on admission. Acute respiratory failure developed hours later. Profuse bloody fluid appeared in the endotracheal tube immediately after intubation. Chest X-ray showed whiteness across all lung fields. He died of persistent shock 16 h after the onset of acute respiratory failure. Autopsy revealed diffuse pulmonary hemorrhage with hyaline-membrane formation, myocarditis, interstitial nephritis and hepatitis. Silver stain of lung and kidney tissue demonstrated leptospires. Immunohistochemical staining showed inducible nitric oxide synthase in alveolar macrophages. Immunofluorescein staining showed immunoglobulin in alveolar septum and alveolar space. This case suggests that hemorrhagic diffuse alveolar damage with persistent shock is related to over-production of nitric oxide and immunoglobulin deposition in fatal leptospirosis.

Arnold-Chiari I malformation (Chiari I) is a congenital disorder characterized by caudal herniation of cerebellar tonsils through the foramen magnum. The symptoms and signs include headaches precipitated by coughing or exertion, dizziness, visual or oculomotor symptoms, dysphagia, trunk or extremity dysesthesias, ataxia, and drop attacks indicating cerebellar or cervical cord lesion. The symptoms may be provoked by increased intracranial pressure. The mean age of onset of symptoms is 25 years; consequently, previously unidentified Chiari I malformations occur in military personnel. Chiari I is associated with deaths following minor trauma, with acute respiratory failure, and with transient quadriparesis occurring in contact sports. Furthermore, Chiari I symptoms may be aggravated by chiropractic manipulation. This report describes symptoms and signs of Chiari I in four military conscripts in the Finnish Defense Forces. It is important to detect Chiari I in military personnel to establish appropriate service fitness and safety for these patients.
