RATIONALE: Lymphomatoid granulomatosis is a very rare Epstein-Barr virus-driven lymphoproliferative disease. This disease has high mortality owing to its low incidence in conjunction with nonspecific presentations, which contribute to delays in diagnosis. PATIENT: An 87-year-old male had a week-long history of intermittent fever and general weakness. A chest radiograph showed multifocal patchy consolidations with nodular lesions. DIAGNOSES: Open lung biopsy using video-assisted thoracic surgery resulted in a diagnosis of grade III lymphomatoid granulomatosis...

Because within-host Mycobacterium tuberculosis diversity complicates diagnosis and treatment of tuberculosis (TB), we measured diversity prevalence and associated factors among 3,098 pulmonary TB patients in Lima, Peru. The 161 patients with polyclonal infection were more likely than the 115 with clonal or the 2,822 with simple infections to have multidrug-resistant TB.

Melioidosis is an infectious disease endemic in Northern Australia and South East Asia. It is associated with high degrees of morbidity and mortality. On average, around five cases are diagnosed annually in the USA. Diagnosis remains a challenge, as it mimics many other conditions, especially tuberculosis, hence its other name, the 'great mimicker.' The present case involves a recent traveler to the Philippines, who presented with episodic fevers and weight loss to his primary care physician. Blood cultures ordered grew Burkholderia pseudomallei...

REVIEW
Savvas Andronikou, Pierre Goussard, Erich Sorantin
Diagnostic imaging plays a significant role in both the diagnosis and treatment of complications of pneumonia in children and chest radiography is the imaging modality of choice. Computed tomography (CT) on the other hand, is not currently a first-line imaging tool for children with suspected uncomplicated community-acquired pneumonia and is largely reserved for when complications of pneumonia are suspected or there is difficulty in differentiating pneumonia from other pathology. This review outlines the situations where CT needs to be considered in children with pneumonia, describes the imaging features of the parenchymal and pleural complications of pneumonia, discusses how CT may have a wider role in developing countries where human immunodeficiency virus (HIV) and tuberculosis are prevalent, makes note of the role of CT scanning for identifying missed foreign body aspiration and, lastly, addresses radiation concerns...

Miliary tuberculosis is a lethal form of disseminated tuberculosis (TB), deriving its name from the millet-seed-sized granulomas in multiple organs. As TB still remains a leading cause of morbidity and mortality in India, its disseminated forms need to be diagnosed early to ensure more aggressive treatment at the earliest possible time. However, a considerable number of cases are missed ante-mortem. We discuss the case of a 32-year-old immunocompromised, non-HIV patient with an ante-mortem diagnosis of pulmonary TB...

We report a case of a patient with esophageal tuberculosis, a very uncommon form of extrapulrhonar tuberculosis. Initially, because of constitutional symptomatology and radiological findings of mediastinal lymph node enlargement, lymphoma was considered. However, the endoscopic findings of ulcerative masses and a sinus tract revealed by esophagram were suspicious of tuberculous origin. Diagnosis was achieved after bacterial examination of smear samples from esophageal ulcers that revealed bacillus tuberculous and histological demonstration of caseating granulomas in cervical lymph nodes...

Miliary tuberculosis is a severe form of tuberculosis resulting from dissemination of Mycobacterium tuberculosis bacilli. Since symptoms appearing in patients due to miliary TB are diverse and atypical, depending on the site of invasion, early diagnosis and treatment are important. A paradoxical response of tuberculosis is a rare phenomenon and it can be a clinical difficulty to treatment especially when involving the central nervous system. We present a case report with a review of related literature about the patient who developed sudden hearing loss due to tuberculosis infection in vestibulocochlear area...

This is a report of an atypical presentation of pyoderma gangrenosum (PG) in a 26-year-old male who had a negative septic screen. The patient had a life-threatening presentation requiring an intensive care unit (ICU) admission for vasopressor support. It was thought that the likely cause of circulatory collapse was an overwhelming cytokine reaction or systemic inflammatory response syndrome (SIRS) secondary to extensive PG lesions rather than septic shock. The patient presented with multiple large ulcers, the largest being 4 cm in diameter on the central chest...

Although the majority of patients with Mycobacterium tuberculosis have pulmonary involvement, some cases have pleural involvement as extra-pulmonary sites of infection. We herein report a case of upper lobe-predominant pulmonary fibrosis that developed in a 47-year-old male with a history of bilateral tuberculous pleurisy. Based on his chest radiological findings, pleuroparenchymal fibroelastosis (PPFE) was most strongly suspected, and a surgical lung biopsy (SLB) was performed to obtain a pathological diagnosis...

Tuberculosis (TB) is a very common health problem in developing nations such as India. It can present as its primary form or as secondary forms (extrapulmonary TB). Maxillofacial manifestations of TB compose nearly 10% of all extrapulmonary manifestations of the disease. Extrapulmonary TB involving the maxillofacial region is very rare and can present in any tissues in this region. These infections generally involve the head and neck through hematogenous or lymphatic routes. Very few cases of primary TB of the temporomandibular joint (TMJ) have been reported in the literature...

The differential diagnosis for lymphadenopathy is wide and clinical presentations overlap, making obtaining an accurate diagnosis challenging. We sought to characterize the clinical and radiological characteristics, histological findings, and diagnoses for a cohort of patients with lymphadenopathy of unknown etiology. 121 Peruvian adults with lymphadenopathy underwent lymph node biopsy for microbiological and histopathological evaluation. Mean patient age was 41 years (Interquartile Range 26-52), 56% were males, and 39% were HIV positive...

Background: Prior to the wide availability of antiretroviral therapy, tuberculosis (TB) and HIV disease among pregnant women resulted in poor maternal and neonatal outcomes including high rates of mother-to-child transmission of both HIV and TB. We aimed to describe the impact of TB among HIV-infected mothers on obstetric and infant outcomes in a population with access to antiretroviral therapy. Methods: In this prospective cohort study, we followed HIV-infected pregnant women with and without TB disease from January 2011 through January 2014 in Soweto, South Africa...

BACKGROUND: KwaZulu-Natal province, South Africa, has among the highest burden of XDR TB worldwide with the majority of cases occurring due to transmission. Poor access to health facilities can be a barrier to timely diagnosis and treatment of TB, which can contribute to ongoing transmission. We sought to determine the geographic distribution of XDR TB patients and proximity to health facilities in KwaZulu-Natal. METHODS: We recruited adults and children with XDR TB diagnosed in KwaZulu-Natal...
