[Erythema nodosum in pediatric patients. A study of 22 cases].

In this study we report the cases of 22 pediatric patients with nodal erythema. The predominance of this condition in male patients was clear. Etiological factors were determined in 77% of the patients. In our series, the principal cause was tuberculosis (36%). We would like to point out the etiological diversity in this small series of children: streptococcal infection, gastrointestinal infection with Salmonella enteritidis or Campylobacter jejuni, cat scratch disease, infectious mononucleosis, chronic hepatitis B, Crohn's disease and pharmacological (amoxycillin). In 22% of the cases no cause was found.

Benign lymphadenopathies in children and adolescents.

This article provides and overview of the benign causes of lymphadenopathy (LA) in the pediatric population. Because of the topics' broad nature, this review is a selective one and primarily focuses on benign conditions of lymph nodes that may be confused with malignant disorders or have been described or better defined in recent years. Specifically, these will include infectious LA caused by Epstein-Barr virus (EBV), human immunodeficiency virus (HIV), and cat scratch disease (CSD), LA associated with vaccination, drug-associated LA, progressive transformation of germinal centers (PTGC), LA associated with autoimmune disorders, histiocytic proliferations involving lymph nodes, and Kawasaki disease.

Bacillary angiomatosis: microbiology, histopathology, clinical presentation, diagnosis and management.

Bacillary angiomatosis is known to be caused by a rickettsial organism; Rochalimaea henselae. This causative agent has been compared with different microorganisms and clinical conditions that appear in similar settings buy have been clearly differentiated from them; e.i. Cat-scratch disease (Afipia felis), Bartonella bacilliformis, other Rochalimaea sp., Kaposi's sarcoma, Lobular capillary hemangioma, Angiosarcoma, and Epithelioid hemangioma. Clinically the bacillary angiomatosis (BA) skin lesions vary from a single lesion to thousands. The cutaneous lesion appears as a bright-red round papule, subcutaneous nodule, or as a cellulitic plaque. When the lesion is biopsied it tends to blanch-out, bleed, and cause pain. The patient might present with signs and symptoms of chills, headaches, fever, malaise, and anorexia with or without weight loss. The extracutaneous lesions found in BA tend to be from multiple organs affecting from the oral lesions to anal mucosal lesions to widespread visceral lesions. The sites of preference for BA lesion manifestation tend to be the liver, spleen, lymph nodes, and bone. To diagnose bacillary angiomatosis the physician should prepare a differential diagnosis based primarily on its histopathological and clinical characteristics. To confirm the results from the stain, electron microscopy can identify the bacillus and pin-point the diagnosis of bacillary angiomatosis. The lesions presented by BA respond well to therapy with erythromycin 500 mg four times daily for a duration of 2 weeks to 2 months. In case of intolerance to erythromycin the second line of drug that successfully treats the BA bacillus is doxycyline. If relapses of the BA lesion recur, then a prolonged antibiotic therapy is necessary and in AIDS patients the duration may be extended as life-long suppressive therapy.

[Detection of Bartonella (Rochalimaea) henselae/B. quintana by polymerase chain reaction (PCR)].

Bartonella (Rochalimaea) henselae and/or B. quintana are the causative agents of a variety of infections such as trench fever, bacillary angiomatosis, septicemia, peliosis hepatis and endocarditis. Recently, B. henselae has been identified as a major cause of cat scratch disease. Diagnosis of such infections is based on clinical information, histopathology, culture and serology. However, none of these methods alone is sufficiently sensitive or specific. We have used the PCR to search for DNA specific for B. henselae/B. quintana in 33 clinical samples and in 6 controls. In comparison with clinical data and histopathology, PCR was extremely specific (100%) and reasonably sensitive (61%). Possible explanations for the limited sensitivity of PCR are discussed. We conclude that PCR provides a useful adjunct for the diagnosis of infections caused by B. henselae and B. quintana.

[Presence of intra- and peri-lymph node color Doppler signals in a case of suppurative granulomatous axillary adenitis].

Recent reports have emphasized that colour Doppler signals in axillary lymph nodes denote their metastatic nature. We report a case of axillary adenitis due to cat scratch disease in which there were both intra and peri-lymph node signals. Doppler colour signals can thus distinguish other pathologies of the axillary lymph nodes since metastatic nodes do not produce perifocal signals.
