RESUMEN
INTRODUCTION: Tuberculous lymphadenitis (TBLN) is the most common infectious etiology of peripheral lymphadenopathy in adults, in Turkiye. This study aimed to identify the demographic, clinical, and laboratory variables that differentiate TBLN from non-tuberculous lymphadenitis (NTBLN), as well as the etiology of lymphadenopathy in adults. METHODOLOGY: Patients who were over 18 years old and were referred to the infectious disease outpatient clinics with complaints of swollen peripheral lymph nodes, and who underwent lymph node biopsy between 1 January 2010 and 1 March 2021, were included in this multicenter, nested case-control study. RESULTS: A total of 812 patients at 17 tertiary teaching and research hospitals in Turkiye were included in the study. TBLN was the most frequent diagnosis (53.69%). The proportion of patients diagnosed with TBLN was higher among females; and among those who had a higher erythrocyte sedimentation rate, positive purified protein derivative test, and positive interferon-gamma release test result (p < 0.05). However, TBLN was less frequent among patients with generalized lymphadenopathy, bilateral lymphadenopathy, axillary lymphadenopathy, inguinal lymphadenopathy, hepatomegaly, splenomegaly, leukocytosis, and moderately increased C reactive protein levels (p < 0.05). CONCLUSIONS: Identifying the variables that predict TBLN or discriminate TBLN from NTBLN will help clinicians establish optimal clinical strategies for the diagnosis of adult lymphadenopathy.

Herpes zoster (HZ) is an infection characterized by the appearance of unilateral painful vesicular lesions on the skin and mucous membranes. Facial paralysis is one of the complications of HZ. The diagnosis of HZ can be easily missed when there is no lesion on the skin. We present a rare case with isolated oral mucosal lesions accompanied by facial palsy.
RESUMEN
OBJECTIVES: The liver biopsy is the gold standard for determining the level of fibrosis in chronic hepatitis B infection (CHBI). Nonetheless, it is possible to predict liver fibrosis through some noninvasive methods such as noninvasive scoring (NIS) of some serum biomarkers obtained from routine blood tests. We aimed to evaluate the diagnostic accuracy of nine NIS for detecting advanced fibrosis in CHBI. PATIENTS AND METHODS: We reviewed the hospital records of CHBI cases with liver biopsy between January 2011 and December 2016 retrospectively. Using Ishak scoring method, we classified fibrosis stage 1-2 as mild and 3-6 as advanced fibrosis. We calculated the NIS by considering the age, platelet count, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, platelet, and international normalized ratio values at the time of the biopsy. RESULTS: The mean age of 202 patients was 37.69± 11.33 years. In cases with advanced fibrosis, the age, gammaglutamyltransferase, and international normalized ratio values were higher and platelet count was lower (P < 0.05). Mean platelet volume was not different between the two groups (P = 0.499). The median values of γ-glutamyl peptidase-platelet ratio (GPR), FibroQ, Goteborg University Cirrhosis Index, fibrosis-4 (FIB-4), aspartate aminotransferase-platelet ratio index, age-platelet index, and King scoring were significantly higher in the advanced fibrosis group. The highest area under the curve value was in GPR [AUC = 0.731 (0.639-0.788); P = 0.000] in the receiver operating characteristic curve analysis. Cirrhosis Discriminant Score and Aspartate aminotransferase-to-alanine aminotransferase ratio tests were not valuable in detecting advanced fibrosis. FIB-4 had the highest (0.678) diagnostic accuracy rate. CONCLUSION: We found that the calculation of NIS before liver biopsy, especially GPR and FIB-4, may be useful for predicting advanced fibrosis in cases with CHBI.
