Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

BACKGROUND: Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed erbium:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed erbium:YAG laser skin resurfacing at the setting of low or high energy for pitted acne scars. METHODS: 65 patients with pitted acne scars were included in this study. All patients had skin types III or IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 mJ/pulse, 3.5-5 W in 45 patients and 1,000 mJ/pulse, 7-10 W in 20 patients was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2 week intervals postoperatively. The results of treatment were evaluated for the changes of skin texture and color at 1 month, 3 months, and 6 months. RESULTS: In 45 cases treated with 500 mJ/pulse energy, pitted acne scars were improved about 46.7 % on average and no erythema and postinflammatory hyperpigmentation was observed after 6 months. In 20 cases treated with 1,000 mJ/pulse energy, pitted acne scars were improved about 64% on average and erythema in two patients and postinflammatory hyperpigmentation in one patient were observed after 6 months. CONCLUSION: The results of laser treatment for pitted facial acne scars at the setting of high energy are better than those of laser treatment at the setting of low energy.

Heorrhage and infarct-like necrosis of anterior lobe of the pituitary gland is one of the characteristic pathologic findings of the autopsied cases of Korean Hemorrhagic Fever (KHF) patients, but there has been rare reports of hypopituitarism in patients with KHF. Recently we have experienced a patient with hyponatremia who had recovered from KHF. He was admitted to our hospital due to nausea, vomiting, and epigastric discornfort. To determine the function of the anterior pituitary gland, hormonal levels of target galnds and pituitary gland were measured, and combined pituitary stimulation test was performed. ACTH, GH, and prolactin deficiency were confirmed by combined pituitary stimulation test in this patient. There was no evidence of hypothalamic or other pituitary diseases by brain MRI. Our experience shows that KHF can be a cause of hypopituitarism and these findings should alert physicians the possibility of hypopituitarisrn in patients who had recovered from KHF.

Herpes zoster oticus (Ramsay Hunt syndrome) is characterized by facial nerve paralysis associated with vesticular eruptions and cochleovestibular symptoms. Many evidences have supported that it is caused by the reactivation of latent varicella-zoster virus in the geniculate ganglion. Recently we experienced a case 49-year-old man presented severe vertigo and a vesicular eruptions of auricle and external ear canal. It is an unusual variant of herpes zoster oticus that involves only vestibular nerve without facial nerve palsy and hearing loss. We believe this case results from reactivation of latent varicella zoster virus in the vestibular ganglion and report with a review of literatures.

OBJECTIVE : To analyze the methylenetetrahydrofolate reductase (MTHFR) mutation in recurrent spontaneous abortion associated with hyperhomocysteinemia. MATERIAL AND METHOD: The blood Sample of habitual aborter with high fasting homocysteine level was tested by PCR-RFLP method. RESULTS: The patient was found to be a homozygosity for MTHFR gene mutation that was confirmed by the finding which is consistent with the mutation at the nucleotide 677 C to T, Corresponding to Ala to Val. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. Therefore, the MTHFR mutation should be examined in the workup of recurrent spontaneous abortion showing hyperhomocysteinemia.

There have been much limitations and errors in evaluating prostatic conditions by traditional radiologic methods due to its location and anatomical structure. However recent introduction and improvement of the ultrasonography have been enabled us to visualize boundary of the prostate clearly and differentiate the variable findings within the prostate. Transrectal or transurethral ultrasonography of the prostate is popular nowadays, however we performed suprapubic ultrasonography of which merits are traumatic to the patients, easy to perform and it requires no adjustments or additions to basic ultrasound equipment. In order to evaluate ultrasonogram of the prostate in patients with prostatic diseases and normal adults and compare preoperative volume of the prostate on ultrasonographic estimation with postoperative volume, 31 patients with prostatic diseases and 40 normal adults under the age 60 were studied with suprapubic ultrasonography. The results obtained were as follows. 1. On ultrasonographic picture of the prostate, normal adults showed symmetrical or triangular or elliptical appearance and there were numerous fine homogenous spots within the prostate. BPH patients showed symmetric, round or oval shapes and its margin was smooth and numerous fine spots were seen within the prostate as normal adults. The prostatic size enlarged and elevated to the bladder base. Advanced prostatic cancer patients showed dyssymmetric irregular appearance. The prostate of acute prostatitis patients resembled normal prostate but prostatic size enlarged. 2. The mean prostatic volume of normal adults on ultrasonographic estimation was 21.30+/-24.80 cm3 and there were no differences of the prostatic volume between ages. 3. The mean prostatic volume of 21 BPH patients on ultrasonographic estimation was 46.2+/-17.2 cm3 and majority patients were in 33.49-61.56 cm3. 4. Comparisonal studies between preoperative ultrasonographic prostatic volume and resected prostatic volume showed correlation coefficient 0.98 (P<0.005) and mean error rate 17.58+/-8.1%. Most cases showed preoperative prostatic volume was larger than the postoperative volume which was probably due to inadequate removal of tissue and surgical capsule. As results of the above, the suprapubic ultrasonography was helpful in differential diagnosis of the prostatic diseases and estimation of the prostatic size.

OBJECTIVES: To investigate the effect of interleukin (IL)-1beta on matrix metalloproteinase (MMP)-9 expression in cochlea and regulation of IL-1beta-mediated MMP-9 expression by dexamethasone and the molecular and signaling mechanisms involved. METHODS: House ear institute-organ of Corti 1 (HEI-OC1) cells were used and exposed to IL-1beta with/without dexamethasone. Glucocorticoid receptor antagonist, RU486, was used to see the role of dexamethasone. PD98059 (an extracellular signal-regulated kinases [ERKs] inhibitor), SB203580 (a p38 mitogen-activated protein kinases [MAPK] inhibitor), SP600125 (a c-Jun N-terminal kinase [JNK] inhibitor) were also used to see the role of MAPKs signaling pathway(s) in IL-1beta-induced MMP-9 expression in HEI-OC1 cells. Reverse transcription-polymerase chain reaction and gelatin zymography were used to measure mRNA expression level of MMP-9 and activity of MMP-9, respectively. RESULTS: Treatment with IL-1beta-induced the expression of MMP-9 in a dose- and time-dependent manner. IL-1beta (1 ng/mL)-induced MMP-9 expression was inhibited by dexamethasone. Interestingly, p38 MAPK inhibitor, SB203580, significantly inhibited IL-1beta-induced MMP-9 mRNA and MMP-9 activity. However, inhibition of JNKs and ERKs had no effect on the IL-1beta-induced MMP-9 expression. CONCLUSION: These results suggest that the pro-inflammatory cytokine IL-1beta strongly induces MMP-9 expression via activation of p38 MAPK signaling pathway in HEI-OC1 cells and the induction was inhibited by dexamethasone.

OBJECTIVE: Cerebral vasospasm is a common and potentially devastating complication of aneurysmal subarachnoid hemorrhage (aSAH). Inflammatory processes seem to play a major role in the pathogenesis of vasospasm. C-reactive protein (CRP) constitutes a highly sensitive inflammatory marker. Elevation of serum CRP levels has been demonstrated in patients with aSAH. The purpose of the current study was to evaluate the possible relationship between CRP levels in the serum and transcranial Doppler (TCD) and the development of vasospasm in patients with aSAH. METHODS: A total of 61 adult patients in whom aSAH was diagnosed were included in the study from November 2008 to May 2011. The patients' demographics, Hunt and Hess grade, Fisher grade, CT scans, digital subtraction angiography studies, and daily neurological examinations were recorded. Serial serum CRP measurements were obtained on days 1, 3, 5, 7, 9, 11 and 13 and TCD was measured on days 3, 5, 7, 9, 11 and 13. All patients underwent either surgical or endovascular treatment within 24 hours of their hemorrhagic attacks. RESULTS: Serum CRP levels peaked on the 3rd postoperative day. There were significant differences between the vasospasm group and the non-vasospasm group on the 1st, 3rd and 5th day. There were significant differences between the vasospasm group and the non-vasospasm group on the 3rd day in the mean middle cerebral artery velocities on TCD. CONCLUSION: Patients with high levels of CRP on the 1st postoperative day and high velocity of mean TCD on the 3rd postoperative day may require closer observation to monitor for the development of vasospasm.

Primary aldosteronism is characterized by hypokalemic metabolic alkalosis, low plasma renin activity, elevated plasma aldosterone level and can be suspected in the patients with hypertension and unexplained hypokalemia. Small adrenal cortical adenomas are responsible for this syndrome in most cases. The incidence of thyrotoxic periodic paralysis ranges from 1.9 to 6.2 % in Japan. Thyrotoxic periodic paralysis usually subsides following treatment of hyperthyroidism and has good prognosis. A 56 year-old man presented with hyperthyroidism, hypertension and recurrent hypokalemia. During the treatment of hyperthyroidism, he repeatedly experienced weakness of both lower extremities. Hormonal evaluation was performed and he was found to have a 2*2*1.5 cm sized right adrenal tumor by abdominal computerized topography(CT). After right adrenalectomy, hypokalemic periodic paralysis was improved. Both thyroid and adrenal function should be comprehensively investigated in periodic paralysis. In conclusion, physicians must be aware of the possibility of primary aldosteronism in hyperthyroid patients with hypokalemic periodic paralysis. We report a case of aldosteronoma complicated with hyperthyroidism and literatures are reviewed.
