A 40-year-old woman was admitted to the hospital with general fatigue and cough. Chest CT films revealed mediastinal lymphadenopathy with multiple low density areas, but no pulmonary lesions. There were no abnormal findings on neck, abdominal or pelvic CT. A PPD skin test was strongly positive, but M. tuberculosis bacilli were not found in the sputum. Mediastinal tuberculous lymphadenitis was diagnosed histologically and bacteriologically from specimens obtained by mediastinoscopy. Fiberoptic bronchoscopy did not reveal tracheobronchial tuberculosis. Follow-up chest CT three months after the start of antituberculosis chemotherapy with isoniazid, rifampicin and ethambutol hydrochloride showed that the mediastinal lymph nodes were decreased in size. Mediastinal tuberculous lymphadenitis in adults is rare, but the number of reports has increased. Mediastinal tuberculous lymphadenitis in adults must be distinguished from other causes of mediastinal masses. In this case, mediastinoscopy was very useful for differential diagnosis.

In recent years, there have been increasing complaints from cockpit crew, cabin crew, and passengers that the cabin air quality of commercial aircraft is deficient. A myriad of complaints including headache, fatigue, fever, and respiratory difficulties among many others have been registered, particularly by flight attendants on long-haul routes. There is also much concern today regarding the transmission of contagious disease inflight, particularly tuberculosis. The unanswered question is whether these complaints are really due to poor cabin air quality or to other factors inherent intlight such as lowered barometric pressure, hypoxia, low humidity, circadian dysynchrony, work/rest cycles, vibration, etc. This paper will review some aspects relevant to cabin air quality such as volatile organic compounds (VOCs), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), particulates, and microorganisms, as well as the cabin ventilation system, to discern possible causes and effects of illness contracted inflight. The paper will conclude with recommendations on how the issue of cabin air quality may be resolved.

A 73-year-old African American female presented to our clinic with painful lower extremity lesions of 2 weeks duration. She was in her usual state of health until 3 months prior to presentation when she reported symptoms of fatigue and weakness. She also noticed an enlarging mass on the left side of her neck. She denied fevers, chills, night sweats or cough. Her symptoms were unresponsive to a course of oral dicloxacillin. The neck mass enlarged over 8 weeks and she was referred to our institution for evaluation. CT scan of the neck showed an enlarged lymph node. Ten days prior to her presentation in dermatology, a fine needle aspirate of the enlarging lymph node revealed necrotizing granulomas. Tissue was sent for routine mycobacterial and fungal cultures. Routine blood work, chest radiograph, and a tuberculin skin test were also performed. At the time of her dermatology visit she described the development of multiple new painful, non-pruritic lesions, bilaterally on the lower extremities. She also reported a red crusted area that appeared at the site of her tuberculin test that was placed subsequent to the development of her lower extremity lesions. Her past medical history was significant for Parkinson's disease, hypothyroidism and hypertension. Her current medications included l-thyroxine, estrogen and diltiazem. Her travel history was only remarkable for a trip to Jamaica the previous spring. She was born and raised in Haiti. She reported a history of a positive tuberculin skin test 20 years ago, but received no therapy. Physical examination revealed a 2 x 3 centimeter firm, nontender left lateral neck mass (Fig. 1). Her right forearm revealed an erythematous, ulcerated, indurated plaque 1.5 cm in diameter (Fig. 2.). Her lower extremities revealed tender 0.5 to 1 cm erythematous nodules below the knees bilaterally (Fig. 3). A punch biopsy of a lower extremity nodule revealed a mild pervisacular dermal infiltrate. Within the subcutaneous tissue there was septal widening. There was also a lymphohistiocytic infiltrate with a slight admixture of neutrophils within the septa of the fat lobules. There was no evidence of necrotizing vasculitis or collagen necrosis. An acid-fast stain was not performed. The histologic findings were consistent with a diagnosis of erythema nodosum. Her laboratory evaluation including CBC, electrolytes, thyroid studies, angiotensin converting enzyme level and chest radiograph were normal. Approximately 1 week after her dermatological evaluation, the fine-needle aspirate culture grew Mycobacterium tuberculosis. A diagnosis of tuberculous lymphadenitis associated with erythema nodosum was confirmed. The patient was started on quadruple therapy of isoniazid, rifampin, ethambutol and pyrazinamide. Her lower limb skins lesions rapidly resolved over the subsequent month and her neck mass also diminished in size. She completed 6 months of antituberculous therapy with complete resolution of her lymphadenopathy.

We report a case of thymoma complicated with miliary tuberculosis. A 69-year-old woman was admitted to a hospital because of body weight loss, general fatigue, and dyspnea. Chest X-ray showed a small, diffuse granular shadows in both lungs. Biopsied-specimens from bone marrow and left pharynx revealed granuloma with both giant cells and caseous necrosis. The diagnosis of miliary tuberculosis was made. The patient was then transferred to our hospital. Both chest X-ray and computed tomography conducted on admission revealed a mass in the mediastinum as well as diffuse granular shadows in both lungs. We suspected a presence of thymoma. Anti-tuberculosis therapy was started, and extended thymectomy was performed. The diagnosis of thymoma was confirmed pathologically. Immunological analysis of peripheral blood lymphocytes was done before and after the operation. Negative conversion of PPD reaction was observed after thymectomy. Although the response of peripheral lymphocytes to phytohaemoagglutinin (PHA) and concanavalin A recovered after thymectomy, a marked decrease of the number of CD 4 T cells, a decrease of T helper 1 cells, a slight increase in the number of B cells and cells expressing natural killer cell-related surface markers were observed throughout the course of illness.

Bone marrow necrosis (BMN) is a relatively uncommon clinicopathologic entity. The etiology is diverse, and malignancy, especially hematopoietic in origin, is the most common underlying disease of BMN. In this retrospective analysis, cases with BMN were re-evaluated for etiology, histopathologic details, and clinical manifestations. In the last 8 years, 23 cases of BMN were detected among the 1,083 bone marrow (BM) biopsies, and the prevalence was found to be 2.2%. Three of these 23 cases with BMN were children, and 20 cases were in adults. Sixteen of these cases (80%) had underlying malignant disease, and four (20%) had nonmalignant disease. Among the malignant cases, three cases had acute myeloblastic leukemia (AML), four had relapsed Hodgkin's disease (R-HD), one had acute lymphoblastic leukemia (ALL), two had chronic myelocytic leukemia (CML), two had non-Hodgkin's lymphoma (NHL), three had disseminated intravascular coagulation (DIC) associated with metastatic solid tumor, and one had myelodysplastic syndrome/myeloproliferative syndrome (MDS/MPS). Among the nonmalignant cases, two had tuberculosis infection, one had anti-phospholipid syndrome (APS), and one had a history of drug ingestion. The most common symptoms were bone pain, fever, fatigue, and jaundice. The most common laboratory findings were variable and associated with underlying disease, but anemia, leukopenia, thrombocytopenia, and high LDH and alkaline phosphatase levels were detected in the majority of the cases, as was also seen in other series. BMN was graded according to the extent of necrosis in the BM biopsy, and necrosis was extensive in 12 cases, moderate in five cases, and mild in three cases. Increased reticulin was found in 16 cases; four cases had severe, eight had moderate, and four had mild fibrosis, and this was found to be an interesting accompanying finding in BMN. In conclusion malignancy is the most common cause of BMN but some nonmalignant conditions such as tuberculosis and APS may be the underlying cause of BMN.

Although vaccines exist against almost 30 different diseases and work remains ongoing on additional new vaccines, many of the currently existing and used vaccines are far from ideal. The vaccines being used by the World Health Organization's (WHO) Expanded Program on Immunization (EPI) against the common childhood diseases of diphtheria, whooping cough, neonatal tetanus, measles, and tuberculosis are reaching 80% of the world's children and saving an estimated 3 million of them annually from death. However, of the almost 13 million child deaths which occur every year, more than 2 million die from vaccine-preventable diseases. Immunization coverage must be improved. Finding sufficient funds to allow immunization programs to sustain their current level of coverage is already difficult and becoming more difficult due to rising vaccine and vaccine delivery costs, donor fatigue, and competing demands upon health and development resources. A super-vaccine is therefore needed which contains in 1 dose all of the antigens required for lifelong protection against the most life-threatening and disabling diseases. The move toward this goal has begun with the development of combination vaccines. A brief historical overview of the development of combination vaccines is presented, followed by consideration of the advantages of combination vaccines and the Children's Vaccine Initiative (CVI) strategy of building upon the diphtheria-tetanus-pertussis (DTP) vaccine.

Diagnosis of tuberculosis (TB) in children is usually based on presumptions from several elements: clinical picture and course, x-rays, tuberculin test, and culture of pathology later on. TB is usually found in a child because of symptoms of primary disease, or through case-finding of a contact. TB is children is often a primary infection and may be gradual or acute in onset. Some of the symptoms of primary TB are low-grade fever, pallor, fatigue, and anorexia. The child may have erythema nodosum, a yellow module on the conjunctiva, hilar or mediastinal lymphadenopathy, a primary TB complex on the lung (3-10 mm), segmental density, or a positive PPD test. Children with pulmonary disease do not have adult-type cavity lesions, but may have a primary cavity that drains into the bronchi, mechanical complications, fistulas, or atelectasis. Acute TB often appears as meningitis. The pathognomonic signs are cerebrospinal fluid high in lymphocytes with very high albumin (0.6-2 g) and low glucose (0.4-0.2 g/l). TB organisms are rarely seen, but may be cultured. TB meningitis is also notable for choroidal tubercles, which are yellow nodules visible in the fundus. These presumptive signs, as well as increasing neurological findings, prompt immediate treatment. Children also may have acute miliary TB, marked by high fever, gastrointestinal symptoms, hepatosplenomegaly, dyspnea, cyanosis, and respiratory distress, with characteristic diffuse grainy spots on the chest x-ray. A child may have both conditions and may also have localized TB infection elsewhere. Thus, clinical findings may point to possible cultures of urine, gastric lavage, pleural fluid or biopsy, pericardial fluid, bone marrow, or ascitic fluid, any of which should be cultured to rule out other causes. The most common sites for extra-pulmonary TB are cervical nodes, spine, knee. shoulder, hip and peritoneum. Pelvic and urinary tract infections are rare in children.

Unclear pulmonary infiltrates with eosinophilia, a problem of differential diagnosis. HISTORY AND ADMISSION FINDINGS: A 60-year-old woman was admitted for the diagnosis of pulmonary infiltrates. A year before she had been exposed to tuberculosis when working as a doctor in Manila, the Philippines. Ten days before admission she had spent 10 days in Sao Paulo, Brazil. On admission she complained of fatigue, dry cough and nocturnal sweating. Her body temperature was 37.8; C. At auscultation of the chest fine rales were heard with diminished percussion sounds over both lungs. INVESTIGATIONS: The chest radiogram showed bilateral apical infiltrates. Blood count indicated normal white and red cells, but platelets were raised to 606 x 10 9/l. The differential blood count revealed an eosinophilia of 30%, ESR was raised at 91 mm/h and C-reactive protein increased to 103 mg/l. Angiotensin-converting enzyme, IgG, IgA, IgM, IgE, C3 and C4, paraproteins, antinuclear antibodies and double-strand DNA antibodies were all within normal limits. There was no direct or indirect evidence of tuberculosis and no parasites were found in sputum, stool, urine and blood. DIAGNOSIS, TREATMENT AND COURSE: After bronchoscopy with bronchial biopsy had failed to establish a diagnosis, an open lung biopsy with partial lung resection was performed. This revealed histologically an eosinophilic pneumonia with intra-alveolar protein precipitation and multinucleated giant cells, as well as interstitial fibroblast proliferation without demonstrable mincroorganisms. Under cortisone administration there was striking improvement of symptoms within a few days, and C-reactive proteins fell to 3 mg/l, ESR to 25 mm/h and the eosino-philia to 2%. CONCLUSION: Eosinophilic pneumonia should be included in the differential diagnosis of unclear pulmonary infiltrations with eosinophilia, once parasitological and malignant diseases, tuberculosis and allergic pulmonary aspergillosis have been excluded.

A 75-year-old man was admitted with cough, purulent sputum, fatigue and weight loss of 10 kg of some months' duration. His chest radiograph showed poorly defined opacities in the right lung. Eleven years before admission an epidermoid carcinoma of the right lung had been diagnosed and a right bilobar resection had been performed. The patient remained asymptomatic for 8 years. Cultures of 4 consecutive sputum samples were positive for mycobacteria that were identified as Mycobacterium szulgai by gas chromatography. A 6-month regimen of rifampin, isoniazid and pyrazinamide resulted in complete eradication of the mycobacterium. M. szulgai is an unusual pathogen in humans. In the English literature, only 35 cases of pulmonary disease have been reported. Its clinical and radiological characteristics are similar to tuberculosis but in contrast to the rest of the non-tuberculous mycobacteria, M. szulgai has shown in vitro and in vivo susceptibility to most primary antituberculosis drugs.
