Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and restricted, repetitive patterns of behavior and interest. Sleep problems are not uncommon in children with autism spectrum disorders. Symptoms of insomnia are the most frequent sleep problems in individuals with ASD. Sleep problems can cause significant difficulties in the daily life of children with ASD and their families. Genetic factor, deregulations of melatonin synthesis, extraneous environmental stimuli and psychiatric and medical conditions may cause sleep problems. The first line treatment of sleep problems in ASD includes managements for potential contributing factors and parent education about sleep hygiene care for child and behavioral therapy. Supplementation with melatonin may be effective before considering other medications, such as risperidone, clonidine, and mirtazapine.

PURPOSE: This study was undertaken to correlate the CT and histopathologic findings of abscess wall. MATERIALS AND METHODS: The CT findings of 12 patients with pathologically proven brain abscess were retrospectively analyzed with particular attention to the thickness, smoothness and uniformity of enhancing abscess wall, and the results were correlated with histopathologic findings. RESULTS: Two patients with acute cerebritis showed an isodense ring on non-contrast CT(NCCT), but a true capsule formation could not be identified at pathologic examination. Six other patients with isodense ring on NCCT consisted of early to late cerebritis(3 cases), late cerebritis to early capsule(1 case), early capsule(1 case), and late capsule(1 case). These 6 cases showed ring enhancement on contrast enhanced CT(CECT) and true capsule formation pathologically. There was no isodense ring on NCCT in the remaining four patients. They consisted of early to late cerebritis(2 cases), late cerebritis(1 case), and late cerebritis to early capsule formation(1 case). These also showed ring enhancement on CECT and true capsule formation pathologically. CONCLUSION: We found that it is difficult to predict the exact stage of brain abscess on preoperative CT findings. It is suggested that clinical findings and sequential dynamic CT may provide more detailed informations for evaluation of abscess staging.

Addison's disease is a rare disorder resulted from a chronic deficiency of the adreanl cortical hormone. The clinical manifestations are general weakness, weight loss, hyperpigmentation, hypovolemia with hyponatremia and hyperkalemia. We report a case of Addison's disease in a 60-year-old woman who has experienced slowly progressive weakness, weight loss and generalized cutaneous pigmentation, especially sun exposed area, extensor surface and nail bed for the last, 2 years. On a hormonal assay of the adrenal glands, basal plasma cortisol level was decreased and basal plasma ACTH level was markedly elevated. A chest X-ray showed streaky tuberculous infiltration in left, upper lobe field and adrenal CT scan showed calcific densities of both adrenal glands with nodular enlargement of right adrenal gland. There was a clinical improvement with steroid replacement therapy and anti-tuber- culosis chemotherapy. A nearly normal appearance was obtained after 5 months' treatment.

Gestational trophoblastic tumor is one of the curable disease, but metastatic trophoblastic tumor still shows high mortality rate because of resistance to the chemotherapy. Choriocarcinoma may occur after an any type of human pregnancy. The incidence of choriocarcinoma following term pregnancy is very uncommon, and such tumor appears to follow a more aggressive course with more extensive metastatic spread and is less responsive to chemotherapy resulting in a poorer prognosis. Choriocarcinoma presenting as postpartum hemorrhage, and spontaneous tumor perforation with intra-abdominal hemorrhage is even rarer, requiring emergency laparotomy. We had experienced one case of metastatic choriocarcinoma following term pregnancy that required emergency total abdominal hysterectomy due to uterine perforation and hemorrhage. So, we report this case with brief review of literatures.

PURPOSE: We present three cases of atypical Harada's disease that exhibited different clinical courses. CASE SUMMARY: (Case 1) A 56-year-old male initially presented with typical findings of Harada's disease accompanied by exudative retinal detachment of the left eye. However, he did not show any signs and symptoms of Harada's disease in his right eye for 4 years. (Case 2) A 73-year-old male came to our clinic complaining of decreased visual acuity in both eyes with headache and tinnitus. Fundoscopic findings showed bilateral annular choroidal detachment but no evidence of exudative retinal detachment. The same result was obtained on remission. (Case 3) A 53-year-old female presented with decreased visual acuity in both eyes with headache and tinnitus. Fundoscopic findings showed severe choroidal folds instead of exudative retinal detachment, which was observed in 2 other remissive cases. CONCLUSIONS: We report 3 cases of atypical Harada's disease that did not present with bilateral exudative retinal detachment. Ophthalmologists should know that Harada's disease can exhibit diverse clinical courses.

Nevus comedonicus is a relatively rare hamartoma, which originates from pilosebaceous unit. The disease usually occurs at birth or during childhood and most commonly unilateral or along with Blascko line. A 59-year-old man presented with black grouped dilated pores, with keratin plug on both eyelids. A histopathologic finding showed multiple keratin filled epidermal invaginations. We herein report an unusual case of bilateral nevus comedonicus developed in middle aged persons.

The most common thyroid dysfunctions that occur after delivery are postpartum thyroiditis (PPT) and Graves' disease (GD). PPT is more likely to occur among patients who had a history of PPT or GD. For that reason, it is possible to assume that both PPT and GD occur concomitantly after delivery. Here we report two cases of atypical postpartum thyroid dysfunctions presenting the simultaneous occurrence of PPT and GD. A 31-year-old woman with history of PPT had thyrotoxicosis and hypothyroidism of PPT followed by GD with mild symptoms. The patient recovered quickly afterwards. In the second case, a 28-year-old woman with a history of GD presented with thyrotoxicosis of PPT followed by severe GD. The patient required long-term antithyroid treatment.

Pachyonychia congenita (PC) is characterized by hypertrophic nail dystrophy, focal palmoplantar keratoderma and blistering, oral leukokeratosis, cyst formation, palmoplantar hyperhydrosis, and follicular keratoses on the trunk and extremities. PC is diagnosed by clinical findings and molecular genetic studies. A 26-year-old man presented with hypertrophic nail dystrophy and subungual debris of all 20 nails, hyperkeratotic plaques on the heels of both soles, and oral leukokeratosis. He had no family history of similar clinical findings. The patient's clinical presentation and history were consistent with PC. Herein we report on a rare case of pachyonychia congenita with a review of literature.
