Rhino-orbito-cerebral muconnycosis is an uncommon fatal fringal infection, almost exclusively seen in diabetic or other itnmunocompromised patients. Recurrent transient ischemic attacks(TIAs) as initial presenting sign of rhino-orbito-cerebral mycormycosis has not been reported to our knowledge. We report a patient with muconnycosis unusually presenting with recurrent TIAs, followed by central retinal artery occlusion, multiple cranial nerve palsies, and then cerebral infarction in the territory of middle cerebral artery.

PURPOSE: In an effort to characterize the complex voiding dysfunction associated with symptomatic diabetic patients, the results of urodynamic studies of diabetic patients were retrospectively analyzed. MATERIALS AND METHODS: We retrospectively reviewed the clinical information, laboratory findings and urodynamic data, of patients with diabetic cystopathy (DCP) (20 males and 40 females) between January 1997 and December 2001. The urodynamic findings were classified as detrusor instability (DI), impaired detrusor contractility (IDC), detrusor areflexia (DA) and normal detrusor contraction (ND). RESULTS: The mean duration of diabetes in irritative symptom group (40%), combined symptom group (26.7%) and obstructive symptom group (33.3%) was 3.4 years, 8.3 years and 15.2 years, respectively (p<0.05). Of the 20 patients with serum HbA1C<7%, 15 were noted in the irritative symptom group. Of the 20 patients with serum HbA1C>or=7%, 17 were noted in the obstructive symptom group. The urodynamic findings of the 60 diabetic patients were distributed as follows: 22 (36.7%) detrusor instability, 20 (33.3%) impaired detrusor contractility, 16 (26.7%) detrusor areflexia and 2 (3.3%) normal detrusor contraction. CONCLUSIONS: The shorter the duration of diabetes, the more predominant were the signs of irritative symptoms, whereas the longer the duration of diabetes, the more predominant were the obstructive voiding symptoms. The patients with serum HbA1C<7% mostly complained of irritative symptoms, but the patients with serum HbA1C>or=7% mostly complained of obstructive symptoms.

Pleomorphic adenoma is the most common neoplasm of the parotid gland, generally presenting as a slowly growing, firm, well-circumscribed, painless nodule. It is often difficult to separate into benign and malignant categories because its bland histomorphologic and cytologic features. This tumor can be rarely associated with cystic change, hemorrhagic necrosis, or spontaneous infarction. Necrosis of lesional tissue may be associated with malignant transformation, particularly in a pleomorphic adenoma. We report a case of 50-year-old woman presented with a enlarging right parotid mass. Computed tomographic scan demonstrated a right superficial lobe mass with ill-defined border. The preoperative fine needle aspiration yielded necrotic debris and atypical squamous elements that were thought to be compatible with high degree of mucoepidermoid carcinoma. A total parotidectomy with intraoperative frozen section revealed extensive necrosis and diagnosed as malignant tumor. This tumor was finally diagnosed as a pleomorphic adenoma with necrosis on permanent sections. Caution should be exercised in evaluation of the parotid neoplasms with central necrosis to avoid misdiagnosis of such lesions as malignancy.

OBJECTIVE: Traumatic brain injury (TBI) in children under age 24 months has characteristic features because the brain at this age is rapidly growing and sutures are opened. Moreover, children this age are completely dependent on their parents. We analyzed the demographic data and risk factors for outcomes in TBI patients in this age group to elucidate their clinical characteristics. METHODS: We retrospectively reviewed the medical records and radiological films of children under 24 months who were admitted to Kyungpook National University Hospital from January 2004 to December 2013 for TBI. Specifically, we analyzed age, cause of injury, initial Glasgow coma scale (GCS) score, radiological diagnosis, seizure, hydrocephalus, subdural hygroma, and Glasgow outcome scale (GOS) score, and we divided outcomes into good (GOS 4–5) or poor (GOS 1–3). We identified the risk factors for post-traumatic seizure (PTS) and outcomes using univariate and multivariate analyses. RESULTS: The total number of patients was 60, 39 males and 21 females. Most common age group was between 0 to 5 months, and the median age was 6 months. Falls were the most common cause of injury (n=29, 48.3%); among them, 15 were falls from household furniture such as beds and chairs. Ten patients (16.7%) developed PTS, nine in one week; thirty-seven patients (61.7%) had skull fractures. Forty-eight patients had initial GCS scores of 13–15, 8 had scores of 12–8, and 4 had scored 3–7. The diagnoses were as follows: 26 acute subdural hematomas, 8 acute epidural hematomas, 7 focal contusional hemorrhages, 13 subdural hygromas, and 4 traumatic intracerebral hematomas larger than 2 cm in diameter. Among them, two patients underwent craniotomy for hematoma removal. Four patients were victims of child abuse, and all of them had PTS. Fifty-five patients improved to good-to-moderate disability. Child abuse, acute subdural hematoma, and subdural hygroma were risk factors for PTS in univariate analyses. Multivariate analysis found that the salient risk factor for a poor outcome was initial GCS on admission. CONCLUSION: The most common cause of traumatic head injury in individuals aged less than 24 months was falls, especially from household furniture. Child abuse, moderate to severe TBI, acute subdural hematoma, and subdural hygroma were risk factors for PTS. Most of the patients recovered with good outcomes, and the risk factor for a poor outcome was initial mental status.

PURPOSE: To observe the hemodynamic change in brain tumors and peritumoral edemas after steroid treat-ment, and then nvestigate the clinical usefulness of perfusion MRI. MATERIALS AND METHODS: We acquired conventional and perfusion MR images in 15 patients with various in-tracranial tumors (4 glioblastoma multiformes, 4 meningiomas, 3 metastatic tumors, 1 anaplastic ependymo-ma, 1 anaplastic astrocytoma, 1 hemangioblastoma, and 1 pilocytic astrocytoma). For perfusion MR imaging, a 1.5T unit employing the gradient-echo EPI technique was used, and further perfusion MR images were ob-tained 2-10 days after intravenous steroid therapy. After processing of the raw data, regional cerebral blood volume (rCBV) maps were reconstructed. The maps were visually evaluated by comparing relative perfusion in brain tumors and peritumoral edemas with that in contralateral white matter. Objective evaluations were performed by comparing the perfusion ratios of brain tumors and peritumoral edemas. RESULTS: Visual evaluations of rCBV maps, showed that in most brain tumors (67%, 10/15), perfusion was high before steroid treatment and showed in (80%, 12/15) decreased afferwards. Objective evaluation, showed that in all brain tumors, perfusion decreased. Visual evaluation of perfusion change in peritumoral edemas revealed change in only one case, but objective evaluation indicated that perfusion decreased signifi-cantly in all seven cases. CONCLUSIONS: rCBV maps acquired by perfusion MR imaging can provide hemodynamic information about brain tumors and peritumoral edemas. Such maps could prove helpful in the preoperative planning of brain tumor surgery and the monitoring of steroid effects during conservative treatment.

We aimed to determine the initial adherence of HIV cohort patients to ART (antiretroviral therapy), and reasons for non-adherence. Patients who received ART at the time of enrollment in the Korea HIV/AIDS Cohort were included in this study. Treatment adherence was determined at the baseline interview by self-reported questionnaire. Eight-hundred thirty two HIV-infected patients received ART. Of these, 253 (30.4%) patients skipped ART more than once a month. The most common reason of skipping medication was “simply forgot” (60.4%).

A 56-year-old male patient with non-Hodgkin's lymphoma achieved complete remission in July 1994 after receiving MACOP-B chemotherapy. 29 months after treatment, acute myeloid leukemia (AML, FAB subtypes M4) with trisomy 9 was developed. To our knowledge this is the first report of therapy-related AML with trisomy 9.
