Varicella gangrenosa with toxic shock-like syndrome due to group A streptococcus infection in an adult: case report.

Varicella gangrenosa is a rare and serious complication of chickenpox that has been described in children only. We describe a case of an adult with varicella gangrenosa that presented as necrotizing fasciitis of a limb. This infection is caused by group A streptococcal superinfection of the skin lesions due to chickenpox. It can be misdiagnosed, with fatal consequences. Because of prompt recognition and aggressive surgical and medical treatment, the patient survived without loss of the affected limb.

Group B streptococcus infection, not birth asphyxia.

This case illustrates 2 main points. Firstly, fetal infection can mimic exactly both the immediate and delayed signs of perinatal asphyxia. Secondly, the placenta may hold the key to the diagnosis of sepsis which may be made difficult in the neonate by labour ward practices such as the use of intrapartum and immediate newborn antibiotics. We strongly support the recommendation that newborn blood and fetal membrane cultures should always be obtained in babies with a diagnosis of 'intrapartum asphyxia and fetal distress' (1). To this we would add the recommendation that placental histology be performed in these circumstances.

[Group A beta-hemolytic streptococcus infection and varicella].

The case of a 3-year-old boy affected with varicella associated to acute cellulitis by group A beta-hemolytic streptococci is reported. The causes of hospitalization were: high fever, decline of condition, onset of scarlet exanthema and a severe swelling in the inguinoscrotal area, during varicella. The diagnosis of streptococcal infection was confirmed by positive pharyngeal tampon, scarlet exanthema and following rise of ASLO. Since the association of these two infections is reported in literature more and more frequently, the possible causes and precautionary measures are analysed.

Presence of Streptococcus infection in extra-oropharyngeal head and neck squamous cell carcinoma and its implication in carcinogenesis.

To investigate the involvement of S. anginosus infection in head and neck cancer in the extra-oropharyngeal cavity, we analyzed 3 DNA samples prepared from squamous cell carcinoma of the external auditory canal and one from squamous cell carcinoma of the skin using polymerase chain reaction (PCR) analysis and Southern blot analysis to detect the DNA sequence of S. anginosus. We also examined these four specimens by Gram's stain to detect the streptococcal bacterial bodies. By PCR analysis, the DNA sequence of S. anginosus was found in 4 out of 4 (100%) DNA samples obtained from these tumors. By Southern blot analysis, positive bands were detected in one out of the 3 (33%) samples from the tumor taken from the external auditory canal. We detected streptococcal bacterial bodies in one of the three specimens from the tumor obtained from cancer of the external auditory canal and in the one specimen from the skin cancer by the method of Gram's stain. Contrary to our expectations, these bacterial bodies were located in the middle of the tumor. Since S. anginosus is thought to exist in the mouth as a normal flora and to be located mainly in the gingiva and dental plaque, these data strongly indicate that S. anginosus infection is implicated in the carcinogenesis of head and neck squamous cell carcinoma.
