A clinical study to assess the pathological involvement of occult supraclavicular lymphnode metastasis in case of locally advanced operable breast carcinoma.

PURPOSE: The prognosis of ipsilateral supraclavicular lymph node (SCLN) recurrence after early breast cancer appears to be worse than for other locoregional recurrences, but better than for distant metastases. Prophylactic radiotherapy (RT) to supraclavicular region decreases risk of ipsilateral SCLN recurrence. Currently, all patients with locally advanced breast cancer are considered high‑risk for SCLN metastasis and treated with prophylactic RT. This study is carried out to identify risk factors associated with occult SCLN metastases in locally advanced breast cancer. MATERIALS AND METHODS:Total 48 female patients of all ages presenting with locally advanced carcinoma of breast who were operable by protocol criteria were included in the study. All the patients underwent modified radical mastectomy with supraclavicular lymphnode dissection. The resected specimen was processed for the histopathological analysis. RESULTS: Occult SCLN metastases are found in 25% (12/48) of the patients in this study. Eleven factors were identified and analyzed to know whether or not they are associated with SCLN metastasis. Of those only pathological N stage (7% for <pN3 vs and 52% for pN3 stage) and level axillary nodal involvement (7% for patients without Level III involvement and 52% for with Level III involvement) are significantly associated with high‑risk for occult supraclavicular lymphnode metastasis. Other factors such as age, menopausal status, T stage, pathologic grade, lymphovascular invasion, extracapsular extension, hormone receptor, and Her2 neu receptor status are not associated with risk for SCLN metastasis. CONCLUSION: Our study has shown that only high axillary disease burden in terms of more than 10 node positivity or more than 75% positive node out of total dissected nodes is associated with occult supraclavicular lymphnode metastasis breast cancer.

Hypervascular nasal metastasis from hepatocellular carcinoma.

Metastases is an uncommon cause of tumors in the sinonasal region. We report a patient with hepatocellular carcinoma which metastasized to the nasal cavity.

The submental island flap for reconstruction of facial defects.

The procedure of facial resurfacing dictates that there should be an excellent colour and texture match between the facial and the transposed skin. Cervical flaps e.g. platysma flap are commonly used for reconstruction of facial defects but, with disadvantages like limited mobility, unacceptable donor site and unpredictable outcomes. The submental island flap is a new addition to the armamentorium of the Plastic Surgeon. It is an axial pattern flap based on the submental branch of facial artery and the submental tributary of common facial vein. We report the use of this flap for the reconstruction of postexcisional facial defects in two patients having basal cell carcinoma and recurrent parotid tumour. In both patients, the flap provided an excellent colour and texture match. Other advantages of this flap are inconspicuous donor site, wide arc of rotation, simple dissection and a reliable pedicle.

Serum and cerebrospinal fluid concentrations of rifampicin at two dose levels in children with tuberculous meningitis.

Twenty patients of tuberculous meningitis (TBM) in age group of 6 months to 10 years included in the study were divided into two groups of 10 patients each. Rifampicin was administered in dosage of 10 mg and 7.5 mg/kg bw to each patient of groups I and II respectively. Drug concentrations in serum and CSF of these patients were measured by a microbiological tube dilution method using a strain of Sarcina lutea. In group I mean serum and CSF concentration was 3.84 micrograms/ml and 0.178 microgram/ml respectively, while in group II it was 2.16 micrograms/ml and 0.206 microgram/ml respectively. These concentrations were many times higher than the MIC against Mycobacterium tuberculosis. Mean percentage penetration of rifampicin in CSF was 5 and 10% in group I and II respectively. We recommend similar studies in large number of children before advocating the therapy with low dose of rifampicin in TBM.
