CASE REPORT: The authors report a case of 43-year-old male patient who presented with the classic symptoms of Plummer Vinson syndrome.
CONCLUSION: Dentists have to be familiar with symptoms of PVS and a thorough clinical examination of the patient is necessary for early diagnosis and treatment. As PVS is a precancerous condition with high malignant potential, early diagnosis is of utmost importance for better prognosis.
CLINICAL SIGNIFICANCE: Mutual interaction of systemic and oral health has largely been underestimated by many patients in the developing countries and hence this report includes a note on importance of adequate medical history taking and its relevance to the dental health and treatment.
RESULTS: Out of 97 patients screened, only 7 were carriers for the 3.7 deletion and all patients were negative for the 4.2 deletion. The 3.7 deletion was found in Foor, Hawsa and Rezagat Sudanese tribes. In the carriers of the 3.7 deletion, Red Blood Cells and Haematocrit were significantly increased. The Red Blood Cells were 7.23 ± 0.78 × 1012/L in adult males and 7.21 ± 0.67 × 1012/L in adult females while in children were 5.07 ± 0.87 × 1012/L. The mean cell volume and mean cell haemoglobin were significantly decreased, but the mean cell haemoglobin concentration slightly decreased. Haemoglobin levels didn't revealed statistically significant decrease in adult males (11.7 ± 0.57 g/dL) and adult females (11.25 ± 0.64 g/dL), while in children were (11.6 ± 2.95 g/dL). Haemoglobin electrophoresis revealed two patients of the 3.7 and 4.2 negative were carriers for β-thalassemia. The study concluded that α3.7 deletion has frequency of 0.07 in Sudanese with hypochromasia and microcytosis.
