A proposed radiological classification of childhood intra-thoracic tuberculosis.

One of the obstacles in discussing childhood tuberculosis (TB) is the lack of standard descriptive terminology to classify the diverse spectrum of disease. Accurate disease classification is important, because the correct identification of the specific disease entity has definite prognostic significance. Accurate classification will also improve study outcome definitions and facilitate scientific communication. The aim of this paper is to provide practical guidelines for the accurate radiological classification of intra-thoracic TB in children less than 15 years of age. The proposed radiological classification is based on the underlying disease and the principles of pathological disease progression. The hope is that the proposed classification will clarify concepts and stimulate discussion that may lead to future consensus.

Splenic vein occlusion secondary to tuberculous lymphadenitis at the splenic hilum: report of a case.

We report a patient with splenic vein occlusion (SVO) secondary to tuberculosis. A 17-year-old male patient with mild epigastric pain and splenomegaly was found to have gastric varices by gastroscopy, and SVO by selective angiography. At operation, the splenic vein was occluded by hard fibrous tissue at the splenic hilum, and thus a splenectomy was performed. A microscopic examination of the tissue revealed caseous necrosis surrounded by epithelioid cells and Langhans-type giant cells. Although there were no other findings suggesting intestinal tuberculosis, it seemed that tuberculous lymphadenitis of the splenic hilum most likely caused the occlusion of the splenic vein. Because specific tests for tuberculosis were negative in both immunohistochemical staining for bacille Calmette-Guérin and polymerase chain reaction of DNA for Mycobacterium tuberculosis, the time of infection was assumed to have occurred a long time before. SVO can sometimes be seen in pancreatic diseases, but this patient with tuberculosis appears to be the first such reported case in the English literature.

Childhood Lichen scrofulosorum revisited.

Lichen scrofulosorum (LS), an uncommon cutaneous tuberculous reaction, has been described in children and young adults. In the last three decades, there has been a dearth of literature on the entity in children, despite a global increase in tuberculosis. It is usually associated with localized cervical, hilar, or mediastinal lymphadenopathy or with osseous tuberculosis. The occurrence of LS in association with pulmonary tuberculosis is rare and its occurrence with generalized lymphadenopathy is unrecognized. We report LS in two children and highlight its occurrence with pulmonary tuberculosis and generalized lymphadenopathy.

Clinical spectrum of paradoxical deterioration during antituberculosis therapy in non-HIV-infected patients.

Paradoxical deterioration during antituberculosis therapy, defined as the clinical or radiological worsening of pre-existing tuberculous lesions or the development of new lesions in a patient who initially improves, remains a diagnostic dilemma. Although different clinical presentations of paradoxical response have been described, a systematic analysis of the entity in non-HIV-infected patients is lacking. Reported here are two cases of paradoxical deterioration in which sequential changes in lymphocyte counts and tuberculin skin test results are emphasized. In addition, 120 episodes of paradoxical response after antituberculosis treatment were reviewed. Of the total 122 episodes, 101 (82.8%) were associated with extrapulmonary tuberculosis. The median time from commencement of treatment to paradoxical deterioration was 60 days. The median time to onset of central nervous system manifestations (63 days) was longer than the time to onset of manifestations at other sites (56 days) ( P=0.02). Development of new lesions in anatomical sites other than those observed at initial presentation was observed in 31 (25.4%) episodes. A surge in the lymphocyte count, accompanied by an exaggerated tuberculin skin reaction, was observed in our patients during the paradoxical deterioration, analogous to the findings in HIV-positive patients. Treatment of the paradoxical response included surgical intervention (60.7%) and administration of steroids (39.3%). The use of steroids appeared to be safe in this series, as 95% of the Mycobacterium tuberculosis isolates were susceptible to first-line antituberculosis therapy.

A year's experience with tuberculosis in a private urban teaching hospital in the postsanatorium era.

Because brief general hospital admission and extended ambulatory management have replaced sanatorium care for tuberculosis, we reviewed 41 cases admitted to a private urban hospital during 1971-1972 to assess the spectrum of disease and the problems created by the closing of sanatoriums. Almost half the cases were misdiagnosed, exposing an average of 35 hospital personnel to unisolated patients with positive smears. Clinical manifestations often were subtle. Of those with pulmonary involvement, 14 per cent denied having symptoms and less than half had positive sputum smears. Transfer to ambulatory care for half the patients was complicated by having different physicians manage their hospital and outpatient care, with poor communication between the two. Outpatient physicians were sent discharge summaries for fewer than two thirds of their patients, and then only after an average 2 1/2 month delay. Similarly, slowness in case reporting impaired contact investigation. Only three contacts were identified per patient, and only 71 per cent of these were investigated. Improved diagnostic ability, better communication with public health workers, and attention to details of transfer to ambulatory care are necessary for effectively integrating the present components of tuberculosis management.

Extrapulmonary tuberculosis. Experience of a community hospital and review of the literature.

Extrapulmonary tuberculosis accounted for 37 percent of all new cases of active tuberculous infection identified at a 522-bed community hospital during an 11-year period. Forty-five foci of extrapulmonary infection were diagnosed in 38 patients. Involvement of the genitourinary system, lymphatic system, and respiratory system, other than the lung, was most common and accounted for 58 percent of all infections. Presenting symptoms were protean and often resulted in long delays between onset of symptoms and eventual diagnosis. Foreign birthplace, prior history of or exposure to tuberculosis, constitutional symptoms, febrile course, and anemia were important findings suggesting the diagnosis. Results of tuberculin skin tests were positive in 31 of 34 patients. Chest radiography demonstrated abnormalities in 25 of 38 patients. Cultures showed growth of Mycobacterium tuberculosis in 27 of 39 affected sites, and caseating granulomas were identified in 31 instances. It is concluded that extrapulmonary tuberculosis remains an important infectious disease problem despite the overall decrease in the national incidence of tuberculosis.

Tracheoesophageal fistula caused by mycobacterial tuberculosis adenopathy.

Tracheoesophageal fistulas resulting from a Mycobacterium tuberculosis infection are uncommon. We describe a patient with such a lesion that had the radiologic and clinic appearance of a malignant tracheoesophageal fistula. Use of an anterior cervical approach with one-stage esophageal repair along with tracheal resection and anastomosis allowed definitive diagnosis and treatment of this life-threatening complication.

Radiological patterns of pulmonary tuberculosis in Nigerian children.

The radiological features of pulmonary tuberculosis in 273 Nigerian children are presented. The commonest lesion lymphadenopathy, was present in 79% followed by parenchymal lesions which were present in 68%. Seventy-two per cent of children with pleural effusions were below 5 years of age while 2 of 13 with cavitation were infants. A majority of cases presented with multiple lesions.

Usefulness of serum lysozyme measurement in diagnosis of intrathoracic lymphadenopathy.

We studied the value of serum lysozyme as a helpful test in distinguising tuberculous involvement of intrathoracic glands from lymphoma. Nineteen of the 28 patients (all Asian immigrants) with intrathoracic glandular tuberculosis had raised serum lysozyme level as compared with 2 of the 29 patients with lymphoma. While a normal serum lysozyme level is unhelpful, a raised level in an Asian immigrant with hilar or mediastinal lymphadenopathy makes tuberculosis a highly probable diagnosis.

Cutaneous vasculitis associated with tuberculosis and its treatment.

Two patients with pulmonary tuberculosis developed cutaneous vasculitis after antituberculosis treatment and a patient with tuberculous lymphadenitis developed vasculitis at presentation before drug therapy. The cutaneous vasculitis probably represented immunological reactions to tubercle bacilli and/or rifampicin with antibodies and immune complex formation.

Factors associated with poor patient compliance with antituberculosis therapy in Northwest Perak, Malaysia.

A retrospective study of factors associated with poor patient compliance with antituberculosis therapy was conducted in Taiping, Perak. 219 patients were studied. Male patients and hospital referrals were significantly more likely to default. Patients with tuberculous lymphadenitis alone had a greater rate of default, but this just failed to reach significance (0.05 less than p less than 0.10). Six of 7 male hospital referrals with tuberculous lymphadenitis alone defaulted. Patients treated as outpatients from the start were more compliant. Housewives were also highly compliant. It was noticed that patients who defaulted tended to do so during early stages of treatment.

Cutaneous tuberculosis: a clinical, histopathologic, and bacteriologic study.

BACKGROUND: In recent years cutaneous infections with Mycobacterium tuberculosis with an atypical clinical appearance have become more common because of the increasing number of immunocompromised patients. OBJECTIVE: We report the clinical, histopathologic, and bacteriologic data of 11 patients with several forms of cutaneous tuberculosis seen during the past 14 years. METHODS: Patients from whom M. tuberculosis was isolated from culture of skin biopsy specimens, sinus drainage, or material aspirated from cutaneous abscesses were included. In all but two patients a biopsy specimen was obtained for histopathologic study. All but one patient received combined antituberculous therapy. RESULTS: The clinical diagnoses were scrofuloderma (four cases), cutaneous miliary tuberculosis (two), lupus vulgaris (two), tuberculous gumma (two), and one unclassified. All but three patients had evidence of either previous or simultaneous tuberculous foci other than in the skin. Histopathologic findings varied according to the type of cutaneous tuberculosis. CONCLUSION: In some patients with cutaneous tuberculosis, lesions are atypical in appearance because of immunodeficiency. Culture for M. tuberculosis should be performed in all suspected cases, even in those in whom special stains for acid-fast bacilli are negative.
