PURPOSE: To investigate the physical and biochemical parameters related with elevated serum alanine aminotransferase (ALT) levels in obese children. METHODS: One hundred forty-two obese or overweight children who visited the out-patient clinics of Chungnam National University Hospital between January 2006 and August 2008 were enrolled. Physical measures and biochemical tests were performed in all patients. Liver sonography was performed in 43 patients. They were divided into the following 2 groups based on ALT levels: group I, normal ALT levels (n=65); and group II, elevated ALT levels (n=77). We compared the physical measures, biochemical results, and ultrasonographic findings of the livers in both groups. Other causes of elevated serum ALT levels were ruled out. RESULTS: The male-to-female ratios were 1.6:1 in group I and 7.6:1 in group II. Among physical parameters, the waist circumference-to-height ratio and hip circumference-to-height ratio were significantly higher in group II (p=0.001 and 0.046, respectively). Among biochemical parameters, aspartate aminotransferase (AST), gamma-glutamyltransferase (gamma-GT), and total cholesterol levels were significantly higher in group II (p<0.001, 0.001, and 0.001, respectively). The AST/ALT ratio was <1 (mean, 0.55) and statistically lower in group II. There was a positive correlation between the serum ALT level and gamma-GT (p<0.001, r=0.750), and a positive correlation between the serum ALT level and the waist circumference-to-height ratio in group II (p<0.001, r=0.401). CONCLUSION: The results suggest that the waist circumference-to-height ratio and gamma-GT may be associated with elevated alanine aminotransferase activity in obese children.

Nasal type natural killer/T-cell lymphoma (NNKTL) is a rare and aggressive subtype of non-Hodgkin lymphoma originating from a natural killer cell or γδ T cell infected by the Epstein-Barr virus. It usually invades the aerodigestive tract and can rapidly destroy the paranasal sinus, hard palate, and central nervous system. NNKTL is often mistaken for benign conditions such as chronic hypertrophic rhinosinusitis or mucosal inflammatory change, as endoscopic findings of NNKTL presenting nasal mucosal hypertrophy are similar to endoscopic findings for these abovementioned benign conditions. Here, the authors report the diagnosis and examination of NNKTL in a 58-year-old male patient who visited our clinic for nasal cavity discomfort after he underwent a dacryocystorhinostomy to treat dacryocystitis.

Primary sinusoidal non-Hodgkin’s lymphoma (NHL) is a very rare disease. The main symptoms of sinusoidal NHL are rhinorrhea, nasal obstruction, and post-nasal drip. Symptoms such as eye protrusion, diplopia, trismus, and periorbital pain can also occur. Epiphora is a very rare symptom of sinusoidal NHL, which can lead to a misdiagnosis of dacryocystitis or dacryostenosis. The authors report the case of a 46-year-old female patient who visited hospital for symptoms of epiphora, which did not improve even after 3 months of eye treatment, leading to a final diagnosis of maxillary NHL.
