The aim of this study was to evaluate children with lymphadenopathy and clinical approach to the suspicion of malignancy. The authors evaluated 457 patients with peripheral lymphadenopathy, less than 19 years of age, and referred to the Pediatric Oncology Department of Gazi University Medical School during the periods March 1996-April 2004. A total of 346 patients had benign disorders and 111 had malignant pathologies. Excisional biopsies were performed to 134 patients. A specific etiology could be found 39% in the benign group. Of the 457 patients, 218 were presented as acute, the rest as chronic lymphadenopathy. In the acute lymphadenopathy group, 98.2% of the patients had benign etiologies. The malignant disorders were mostly represented as chronic lymphadenopathy. Concerning the extension, 193 patients had localized lymphadenopathy and 264 had generalized lymphadenopaties. Cervical region was the most frequent site in both localized and generalized lymphadenopathy groups. Malignancies occurred as generalized lymphadenopathy. Supraclavicular area were involved only in the malignant group. Axillary involvement was predominant in BCG vaccine associated lymphadenitis and mycobacterium tuberculosis. All the lymph nodes less than 1 cm were due to benign causes. The malignant lesions were usually more than 3 cm in diameters. The following findings should alert the pediatrician for the probability of a malignant disorder: lymphadenopathy of more than 3 cm in size, of more than 4 weeks in duration, with supraclavicular involvement, and with abnormal laboratory and radiological findings.

More than half of the patients used CAM, with stinging nettle being the most common agent. Our patients place a high level of trust in their physicians and the conventional therapies offered by them; however, they also believe that the complementary therapies are harmless and, therefore, worth trying.

The aim of this study was to investigate the late effects of treatment for childhood non-Hodgkin's lymphomas (NHL) on oral health and dental development. Thirty-six long-term survivors that had been treated with chemotherapy of childhood NHL were included in this study and 36 volunteers with similar age and sex distribution served as controls. Both groups underwent a complete orodental examination for decayed, missing and filled teeth and surfaces, gingival and periodontal health according to the Loe-Silness Gingival Index and Sillnes-Loe Plaque Index, enamel defects and discolorations, root malformations, eruption status, agenesis, premature apexifications and microdontia. The severity of these disturbances related to age at the time of NHL diagnosis were also evaluated by creating two groups as < 5 yr and > 5 yr. Although none of the parameters altered with age, patients had significantly higher plaque index, more enamel discolorations and root malformations than did the controls. The results show that long-term survivors of NHL patients exhibit some orodental disturbances that may be attributed to the chemotherapy regimens.

This prospective study evaluated 382 pediatric patients with peripheral lymphadenopathy (LA) presenting at the Pediatric Oncology and Hematology Departments of Social Security Children's Hospital and Gazi University Medical Faculty Hospital. The ages of the patients ranged between 2 months and 16 years (median 7 years); 72% of the patients were male. Of the 382 patients, 138 had localized LA (a single anatomic area involved), 171 had limited LA (two or three areas involved), and 73 had generalized LA (four or more anatomic areas involved). The specific etiology (either benign or malign) was defined in 79% of patients with generalized LA. However, in patients with localized LA and limited LA, specific etiology could be identified only in 43 and 53% of patients, respectively. Based on this study, BCG-LA and pyogenic infections are more frequently manifested by localized LA; LA of unknown origin, Hodgkin's disease, tuberculosis, nasopharyngeal carcinoma, and toxoplasmosis are frequently manifested by localized or limited LA; and cytomegalovirus infection (CMV), infectious mononucleous, rubella, acute leukemia, non-Hodgkin's lymphoma are frequently manifested by limited or generalized LA. Out of 382 patients, 196 patients had a maximum lymph node diameter of less than 2 cm. A benign etiology was shown in 159/196 of these patients. In 37/196 of these patients LA was due to a malignancy, and these cases almost invariably had some apparent additional diagnostic clinical and laboratory findings. Based on this observation a maximum lymph node size of 2 cm was considered an appropriate limit to distinguish malignant disease from benign causes except when there is other evidence of an underlying malignant disease. However, lymphadenopathies located at supraclavicular region (27 patients) either localized or as part of generalized LA had a specific benign or malignant disease in etiology (malignancy in 20, tuberculosis in 3, CMV in 2, sarcoidosis in 1, and lipoma in 1) even though they were less than 2 cm in diameter.
