Facial infiltrating lipomatosis: A case report and review of literature.

Infiltrating lipomatosis of the face has been described as a congenital disorder in which mature lipocytes invade adjacent tissues in the facial region. The presentation is always unilateral with hypertrophy of hard and soft structures on the affected side of the face. We present a case of a 27-year-old female who reported with a complaint of recurrent unilateral facial swelling with history of two previous resections, the histopathology or details of these surgeries were not available. The patient underwent resection of tumour and the histopathology confirmed it to be infiltrating lipomatosis. The surgery resulted in a definite improvement in the facial asymmetry and the patient is being closely followed up with no evidence of recurrence. The pathogenesis of the condition is unclear, though it has been postulated that the condition is at one end of a spectrum of overgrowth syndromes with classic Proteus syndrome on the other extreme. Management of this condition involves resection of the tumour which in most cases is subtotal to reduce the risk of damage to facial nerve. There is a controversy regarding both timing and extent of resection in the literature and we think the subtotal resection of tumour in an adolescent or older patient can give good aesthetic outcome without compromising facial nerve function. However, the patients should be informed about high rate of recurrence and increase risk of complications with any subsequent surgery.

Infective complications of tattooing and skin piercing.

Body piercing appears to be gaining popularity and social acceptance. With the increase in the number of piercings and tattoos, it is likely that health care providers may see an increase in the complications resulting from these piercings. These may include the transmission of hepatitis viruses and bacteria at the time of the piercing or in the course of wound care. We review the infectious complications that have resulted from body piercing and tattooing that has been documented in the medical literature.

Relation of a hypoxia metagene derived from head and neck cancer to prognosis of multiple cancers.

Affymetrix U133plus2 GeneChips were used to profile 59 head and neck squamous cell cancers. A hypoxia metagene was obtained by analysis of genes whose in vivo expression clustered with the expression of 10 well-known hypoxia-regulated genes (e.g., CA9, GLUT1, and VEGF). To minimize random aggregation, strongly correlated up-regulated genes appearing in >50% of clusters defined a signature comprising 99 genes, of which 27% were previously known to be hypoxia associated. The median RNA expression of the 99 genes in the signature was an independent prognostic factor for recurrence-free survival in a publicly available head and neck cancer data set, outdoing the original intrinsic classifier. In a published breast cancer series, the hypoxia signature was a significant prognostic factor for overall survival independent of clinicopathologic risk factors and a trained profile. The work highlights the validity and potential of using data from analysis of in vitro stress pathways for deriving a biological metagene/gene signature in vivo.

Psychological outcome of patients following treatment of oral cancer and its relation with functional status and coping mechanisms.

BACKGROUND: Traditionally health-care providers have measured outcome of treatment of disease by focusing on tumour response and disease-free survival. However, it has become increasingly apparent that the behavioural and functional impact of treatment on the patient is important. This study investigates the psychological outcome and its relationship with functional status and coping mechanisms following treatment of oral cancer patients. MATERIAL AND METHODS: Sixty-eight patients were evaluated 6 months to 6 years after treatment (from October 1992 to October 1997) for oral cancer. The Hospital Anxiety and Depression Scale (HADS) was used for psychological evaluation, the University of Washington Quality of Life Questionnaire (UW-QOL) and The European Organisation for Research and Treatment of Cancer Questionnaire (EORTC QLQ-C30) for evaluating the head and neck specific and general functional status, respectively. Finally, the "Mental Adjustment to Cancer Questionnaire" (MAC-Q) was used for evaluation of coping mechanisms. RESULTS: The incidence of anxiety and/or depression was 25% and the socio-demographic and medical characteristics showed poor correlation with the psychological outcome in this study. The results indicated that there was a strong association between psychological outcome and head and neck specific and general quality-of-life (QOL) domains, and style of coping. The p-value was less than 0.01 for most of the domains and items of functional status and the effective coping style. CONCLUSION: Deteriorated functional status and ineffective coping strategies are strongly associated with poor psychological outcome in patients with oral cancer.
