ABSTRACT
The aim of this study was to investigate the usefulness of a clinical screening test [the Korean Infant and Child Developmental Test (KICDT)] compared to language specific tests: the sequenced language scale for infant (SELSI) and the Preschool Receptive-Expressive language Scale (PRES) in children with delayed language development. A retrospective chart review was conducted on 615 children who visited the Department of Pediatrics at Chonbuk National University Hospital from January 2013 to December 2016. All patients were evaluated with KICDT as a clinical screening test and SELSI or PRES as a language specific test. Language Developmental Quotients (LDQs) from the KICDT were compared with the Receptive Language Quotient (RLQ) and expressive language quotient (ELQ) from the SELSI or PRES. The sensitivity, specificity and predictive values of LDQ of KICDT were calculated by comparing with SELSI/PRES. Language DQs from the KICDT were significantly correlated with the RLQ (r=0.706), ELQ (r=0.768), and total language quotient (TLQ) (r=0.766) from the SELSI/PRES (p<0.05). In cross tabulation, the patients belonging to the retardation groups in both KICDT and SELSI/PRES were 417 (67.8%). Otherwise, patients belonging to the normal group in KICDT but not in SELSI/PRES were 151 (24.6%). Sensitivity and specificity of LDQ of KICDT relative to SELSI/PRES were 72.3% and 92.2% respectively (p<0.05). Our data suggests that clinical screening tests alone, not cumbersome language specific tests, can determine language developmental delays in children.
ABSTRACT
Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular shaped mass with spiculated margin at the left upper lobe. Despite no elevation of serum IgG4 level, he was finally diagnosed as IgG4-related lung disease by transthoracic needle biopsy. After treatment with oral glucocorticoids, hemoptysis disappeared and the size of lung mass was decreased.
ABSTRACT
We report a case of agranulocytosis caused by ethambutol in a 79-year-old man with pulmonary tuberculosis. He was referred for fever and skin rash developed on 21th day after antituberculosis drugs (isoniazid, rifampicin, ethambutol, and pyrazinamide) intake. Complete blood count at the time of diagnosis of pulmonary tuberculosis was normal. On the seventh admission day, agranulocytosis was developed with absolute neutrophil count of 70/µL. We discontinued all antituberculosis drugs, and then treated with granulocyte colony-stimulating factor. Three days later, the number of white blood cell returned to normal. We administered isoniazid, pyrazinamide, and ethambutol in order with an interval. However, fever and skin rash developed again when adding ethambutol, so we discontinued ethambutol. After these symptoms disappeared, we added rifampicin and ethambutol in order with an interval. However after administering ethambutol, neutropenia developed, so we discontinued ethambutol again. He was cured with isoniazid, rifampicin, and pyrazinamide for 9 months.
ABSTRACT
OBJECTIVE: To evaluate the antiepileptic effect of low-frequency rTMS (repetitive transcranial magnetic stimulation) in the patients with intractable epilepsy. METHODS: We enrolled 35 patients with localization-related epilepsy who had experienced at least one complex partial seizure or a secondarily generalized seizure per week on a constant antiepileptic drug regimen over an 8-week period. rTMS was administered using a Rapid(2) magnetic stimulator with an air-cooled coil at 0.5Hz for 5 consecutive days at 100% of rMT (resting motor threshold). Patients were divided into a focal stimulation group with a localized epileptic focus, or a non-focal stimulation group with a non-localized or multifocal epileptic focus. These two groups were then randomly subdivided into four subgroups depending on the total number of stimulations administered, i.e., 3000 pulse and 1500 pulse subgroups. Weekly seizure frequencies were determined for 8 weeks before and after rTMS. To compare the number of interictal spikes before and after rTMS, EEG was recorded twice before (1st day) and after rTMS (5th day). RESULTS: Mean weekly seizure frequency was non-significantly decreased after rTMS (8.4-->6.8/week, -13.9%). Longer stimulation subgroups (3000 pulses, -23.0%) tended to have fewer seizures than shorter stimulation subgroups (1500 pulses, -3.0%), without statistical significance. TMS stimulation site and structural brain lesions did not influence seizure outcome. However, interictal spikes significantly decreased (-54.9%, P=0.012) after rTMS and they totally disappeared in 6 patients (17.1%, 6/35). CONCLUSIONS: Low-frequency rTMS reduced interictal spikes, but its effect on seizure outcome was not significant. Focal stimulation for a longer duration tended to further reduce seizure frequency. SIGNIFICANCE: These findings may help clinicians to further investigate the therapeutic potential of the rTMS for patients with intractable epilepsy.
