A case of a 74-year-old male with unilateral nasal obstruction, recurrent epistaxis and a right intranasal mass is presented. It was initially diagnosed as hemangioma but final histopathology report revealed oncocytic carcinoma. Oncocytic carcinoma is a rare tumor of the salivary glands with very few reported cases, most of which involve the parotid gland. It has a tendency to recur with inadequate excision. Diagnosis is histopathologic. It is to be emphasized that adequate tissue samples should be taken in order to provide a definite diagnosis from biopsy, and subsequently institute proper definitive management.

Polymorphisms in metabolic genes have been shown to modulate susceptibility to oral cavity cancer. Cases (n=176) and controls (n=317) from the Filipino population were genotyped for selected polymorphisms in CYP1A1, GSTM1, GSTP1, GSTT1, NAT1 and NAT2. Medical and diet histories, occupational exposure and demographic data were also collected for all subjects. The CYP1A1m1/m1 genotype is protective against oral cancer, while being homozygous for the GSTP1 c.313G genotype and heterozygous for the NAT1*10 homozygotes and non-homozygotes for the CYP1A1 m1 allele. The risk from heterozygosity for the NAT1*10 allele was limited to subjects who were not homozygous for the GSTP1 c.313G genotype remained a significant oral cancer risk modifier, together with environmental variables, the homozygous GSTP1 c.313G genotype remained a significant oral cancer risk modifier, together with environmental risk factors, such as smoking, passive smoking, inverted smoking and tobacco chewing, and environmental protective factors, i.e. moderate consumption of fish sauce (patis) and shrimp paste (bagoong). The GSTP1 c.313G polymorphism increases susceptibility for oral cavity cancer in the Filipino population.

OBJECTIVE: To  report  a  case  of  tumoral  calcinosis  from  secondary hyperparathyroidism  and  to describe its surgical management.
METHODS:
 Design: Case Report
 Setting: Tertiary Public University Hospital
 Patient: One
RESULTS: A 34-year-old woman presented with progressively-enlarging bilateral upper extremity masses. Diagnostic tests revealed hyperfunctioning parathyroid glands. The patient underwent subtotal  parathyroidectomy,  right  thyroid  lobectomy  with  isthmusectomy,  and  transcervical thymectomy.    Follow-up  revealed  marked  decrease  in  parathyroid  hormone,  and  progressive resolution of the tumoral calcinosis.
CONCLUSION: Subtotal  parathyroidectomy  and  transcervical  thymectomy  have  a  role  in  the management  of  tumoral  calcinosis,  and  in  this  case  led  to  excellent  post-operative  results. The rare  presentation  of  secondary  hyperparathyroidism  and  intervention  in  this  patient  may  have potential lessons for future management of similar cases.

OBJECTIVE: To describe a surgical technique in the treatment of arteriovenous malformations of the mandible

METHODS:

       Design:    Case Report

       Setting:    Tertiary National University Hospital

       Participant:        One

RESULT: A 16-year-old boy underwent resection, extracorporeal curettage, and immediate replantation of the hemimandible for intraosseous arteriovenous malformation. Postoperative follow up and imaging at one- and six-months showed no signs of recurrence, new bone formation and consolidation of the replanted right mandible with good symmetry and function.

CONCLUSION: Extracorporeal curettage followed by immediate replantation of the resected mandible seems to have yielded good early results in our case and may be a viable alternative especially when access to highly specialized microvascular surgical services is limited.

Objectives. Polymorphisms in metabolic genes which alter rates of bioactivation and detoxification have been shown to modulate susceptibility to colorectal cancer. This study sought to evaluate the colorectal cancer risk from environmental factors and to do polymorphism studies on genes that code for Phase I and II xenobiotic metabolic enzymes among Filipino colorectal cancer patients and matched controls. Methods. A total of 224 colorectal cancer cases and 276 controls from the Filipino population were genotyped for selected polymorphisms in GSTM1, GSTP1, GSTT1, NAT1 and NAT2. Medical and diet histories, occupational exposure and demographic data were also collected for all subject participants.Results. Univariate logistic regression of non-genetic factors identified exposure to UV (sunlight) (OR 1.99, 95% CI: 1.16-3.39) and wood dust (OR 2.66, 95% CI: 1.21-5.83) and moldy food exposure (OR 1.61, 95% CI:1.11-2.35) as risk factors; while the NAT2*6B allele (recessive model OR 1.51, 95% CI :1.06-2.16; dominant model OR 1.87, 95% CI: 1.05-3.33) and homozygous genotype (OR 2.19, 95% CI: 1.19-4.03) were found to be significant among the genetic factors. After multivariate logistic regression of both environmental and genetic factors, only UV radiation exposure (OR 2.08, 95% CI: 1.21-3.58) and wood dust exposure (OR 2.08, 95% CI: 0.95-5.30) remained to be significantly associated with increasing colorectal cancer risk in the study population.Conclusion. This study demonstrated that UV sunlight and wood dust exposure play a greater role in influencing colorectal cancer susceptibility than genotype status from genetic polymorphisms of the GST and the NAT` genes.
