Pharyngeal Papilloma: a Rare Non-Pulmonary Cause of Hemoptysis.

The most common benign neoplasm of the pharynx is papilloma. It is characterized by bulging brittle lesions, which are pedicled or sessile, whitish-grey or pinkish colour. Progressive hoarseness is the main clinical feature. When the papillomata spread throughout the tracheobronchial tree symptoms such as chronic cough, stridor, dyspnea or acute respiratory distress are mostly present. Hemoptysis as a presenting symptom is exceptionally rare in patients with pharyngeal papillomatosis. Herein, we report a case of pharyngeal papillomatosis in which hemoptysis was the primary clinical manifestation. The clinical and therapeutic aspects of the disease are briefly discussed.

Gemcitabine-induced severe peripheral edema in a patient with lung cancer.

Gemcitabine, alone or in combination with a platinum-based agent, is indicated for the first-line treatment of patients with locally advanced or metastatic non-small-cell lung cancer. It is generally a well-tolerated drug. Despite its lack of significant toxicity, the most commonly reported side effects include myelosuppression, gastrointestinal disturbances (eg, nausea and vomiting), influenza-like symptoms, skin rash with pruritus, and elevation of liver transaminase enzymes. Peripheral edema has rarely been described as an adverse effect. Herein, we report a patient with advanced non-small-cell lung cancer who experienced severe peripheral edema after gemcitabine administration. Immediate gemcitabine discontinuation and the administration of diuretics resulted in definite regression of peripheral edema.

The Challenging Evaluation of Patients with Severe Psoriasis for Latent Tuberculosis: An Important Indication for IGRA.

It is well-established that tumour necrosis factor (TNF)-α-antagonist regimens are advisable for the control of moderate to severe psoriasis; however the application of these agents is associated with increased risk of TB reactivation. Screening for latent tuberculosis infection (LTBI) is indispensable prior to treatment inception in order to diminish the risk of active TB. Although tuberculin skin test (TST) still represents a useful tool for LTBI detection, it is difficult to be performed and read in patients with extensive psoriatic lesions. In this paper, we report the case of a 65-year-old male with severe psoriasis, who was evaluated by an interferon-gamma release assay (IGRA) for LTBI diagnosis prior to anti-TNF-α therapy. Furthermore, the physiological aspects of interferon-gamma release assays are discussed emphasizing the value of these novel immunodiagnostic tests (IGRAs) for presumable LTBI in all patients with extensive skin disorders.

Use of interferon-gamma release assay for latent tuberculosis infection screening in older adults exposed to tuberculosis in a nursing home.

OBJECTIVES: To assess the additive value of a newly marketed interferon-gamma release assay, QuantiFERON-TB Gold In-Tube (QFT-GIT), to a single tuberculin skin test (TST) for the detection of latent tuberculosis infection (LTBI) in older adults who have been exposed to TB in a nursing home. DESIGN: Contact tracing included clinical examination, chest radiography, TST, and QFT-GIT in TST-negative people (TST< 5 mm). SETTING: A private nursing home. PARTICIPANTS: Seventy-seven individuals (63 elderly residents, 14 young employees) who had been exposed to an active TB case in a private nursing home. MEASUREMENTS: Comparison of TST and QFT-GIT in older adults who have been exposed to TB. RESULTS: For the TST, the positive response rate was 31.7% (n=20) of elderly residents and 43% (n=6) of staff. Positive QFT-GIT results were obtained in seven (16.3%) elderly residents with negative TST, six of whom were aged 80 and older. QFT-GIT increased the percentage of possible LTBI in this group from 31.7% to 42.9%. CONCLUSION: QFT-GIT has a significant additive value to single TST for detecting LTBI in institutionalized older adults, identifying infected subjects anergic to the TST.

Chronic eosinophilic pneumonia associated with neurofibromatosis type 1: an unusual complication.

Neurofibromatosis type 1 (formerly known as von Recklinghausen's disease) is an autosomal dominant disorder, which results from the proliferation of the neural crest cells, thus affecting any organ system. Several pulmonary manifestations have hitherto been reported, including chest wall deformities, diffuse lung disease, thoracic neoplasms, pulmonary arterial hypertension, central hypoventilation, diaphragmatic paralysis and meningocele. However, eosinophilic lung disorders have not been described. An unusual case of chronic eosinophilic pneumonia in a patient with neurofibromatosis type 1, is reported herein. He had a propitious outcome, following corticosteroid treatment. This is the first well-documented case of chronic eosinophilic pneumonia and neurofibromatosis type 1 in the same patient. These clinical entities might share common pathogenic mechanisms, as suggested by the present study, that could explain their co-existence.

Mefloquine-induced eosinophilic pneumonia.

Mefloquine has been widely used for prophylaxis and treatment of patients with chloroquine-resistant malaria; the drug is usually well tolerated. Rarely, adverse effects may be severe, including gastrointestinal disturbances, neuropsychiatric reactions, cardiovascular manifestations, skin lesions, musculoskeletal symptoms, and bone marrow toxicity. We describe a 67-year-old woman with fever, dyspnea on exertion, peripheral blood eosinophilia, and diffuse pulmonary infiltrates on chest radiography. She had taken mefloquine for malaria prophylaxis for an 8-week trip to South Africa. A thorough work-up led to the diagnosis of eosinophilic pneumonia caused by the mefloquine. Her condition improved after the drug was discontinued. To our knowledge, this is the first report of mefloquine-induced eosinophilic pneumonia. Clinicians should be aware of this rare, potential adverse effect of mefloquine.

Pulmonary sarcoidosis associated with psoriasis vulgaris: coincidental occurrence or causal association? Case report.

BACKGROUND: Sarcoidosis is rarely associated with a distinct disease. One disease infrequently associated with sarcoidosis is psoriasis. CASE PRESENTATION: This case study describes a 38-year-old male, who presented with chest pain, high-grade fever, arthralgias and a skin rash accompanied by bilateral hilar lymphadenopathy on his chest radiograph. Extensive investigations including fiber-optic bronchoscopy with bronchoalveolar lavage and labial and skin biopsies, demonstrated that two distinct clinical entities co-existed in the same patient: pulmonary sarcoidosis and psoriasis vulgaris. Combination therapy for both diseases was applied and the patient was greatly improved. CONCLUSION: This is the first well-documented case of sarcoidosis and psoriasis in the same patient, reported on the basis of safe and widely-used techniques that were not available until fairly recently. These disorders might share common pathogenic mechanisms that could explain their co-existence in the patient.
