Targetoid hemosideric hemangioma represents a distinctive, benign, vascular tumor. Histologically, it is a noncircumscribed vascular proliferation that may extend into the subcutaneous tissue. The superficial component is composed of ectactic dermal vascular lumina with intradermal papillary projections. The deeper component is composed of angular lumina dissecting collagen bundles. We present a case of targetoid hemosideric hemangioma which was presented as solitary nodule on left thigh.

Calcific myonecrosis is a rare late post-traumatic condition in which an entire single muscle is replaced by a fusiform mass with central liquefaction and peripheral calcification. The compartmental syndrome is suggested to be the underlying cause. We report a case of 70 year-old man whose right tibialis anterior and extensor hallucis longus muscle were replaced by calcific myonecrosis and treated with en-bloc resection & tendon reconstruction.

This study was designed to evaluated the effects of opioid receptor agonists on the spontaneous alternation behaviour in an animal model of obsessive-compulsive disorder in rats. According to the theory that dopamine is related to the biological etiology of obsessive-compulsive disorder, the effect of the nalbuphine(opioid kappa agonist) and the tramadol(opioid mu agonist), which act as manipulating agents on the inhibition or stimulation of dopamine release, in the spontaneous alternation behaviour were evaluated. 24 hours prior to the experiment, rats were food-deprived. These rats were put into the T-maze, in which white and black goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose the one of the goal boxes for each time. After identifying the stable baseline of spontaneous alternation behaviour, nonselective 5-HT agonist 5-MeODMT(1.25mg/kg/IP) disrupted spontaneous alternation. Rats were stratified into fluoxetine(10mg/kg/IP), nalbuphine(10mg/kg/IP), tramadol(46.4mg/kg/IP), and saline(0.5cc/IP) injection group with experimental drug treatment for 21 days. The effects on the 5-M?DMT(1.25mg/kg/IP) induced disruption of spontaneous alternation behaviour were checked at the next day of discontinuation of drug treatment. The results were as follows : 1) At the day after 21 days of the drug treatment, the nalbuphine treated group and the fluoxetine treated group showed significant difference from the tramadol treated group and the saline treated group in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. 2) Within each drug treatment group, the fluoxetine treated group showed significant difference between before and after the treatment of fluoxetine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. And also, the nalbuphine treated group showed significant difference between before and after the treatment of nalbuphine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. There was no difference between the baseline and after the treatment of nalbuphine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. We indentified that the opioid kappa agonist that act as dopamine release inhibitor affect the spontaneous alternation behaviour which is an animal model of obsessive-compulsive disorder in rat.

Although cases of von Hippel-Lindau syndrome are not rare, the fact that hemangioblastomans can occur at sites in the nervous system other than the cerebellum is not appreciated. We are reporting a case of VHL complex in 23-year-old male. In this case, there were multiple cerebellar hemangioblastomas, retinal angiomas, multiple spinal hemangioblastomas, syringomyelia, and papillary cystadenoma of epididymis. There was no evidence of polycythe mia or abnormality of other organs. Large cystic cerebellar hemangioblastomas were removed surgically and papillary cystadenoma of epididymis were excised, too. Total laminectomy of T2, T3 and T4 revealed abnormal meningeal varicosities, enlarged spinal cord, inra-axial hemangioblastomas, and syringomyelia.

Aneurysms of the posterior cerebral artery are rare, furthermore giant serpentine aneurysms-partially thrombosed aneurysms containing a tortuous vascular channel-of the posterior cerebral artery are extremely rare. The author et al. were able to remove 3.9cm x 2.9cm x 3.0cm sized giant serpentine aneurysm of the distal PCA totally, without any significant postoperative neurological sequela except transient ipsilateral third cranial nerve paresis and transient hemihypesthesia. Various kinds of surgical treatment were proposed by several authors in managing unclippable giant aneurysms:excision including partial excision;clipping of feeding artery and excision;trapping and excision;revascularization and excision;anastomosis only. We took subtemporal approach under the surgical microscope and trapping & excision was performed in several steps:proximal clipping of the PCA distal to the Pcom-PCA junction;reducing volume of the mass through piecemeal resection of the aneurismal wall;distal clipping of the PCA;total excision and final trapping just proximal and distal to the origin of the aneurysm. We are discussing the characteristics of the giant serpentine aneurysm, precognition of rich collateral circulation of the PCA distal to trapping and surgical management of the giant serpentine aneurysm.

The Good’s syndrome is a rare immunodeficiency disease characterized by thymoma and hypogammaglobulinemia. The most common cause of infection in patients with Good’s syndrome is the recurrent sinopulmonary infection. One may assume that there could be an unknown immunocompromising condition such as Good’s syndrome in cases of chronic rhinosinusitis refractory to treatment. We experienced a patient with Good’s syndrome, presenting with chronic rhinosinusitis refractory to treatment. We report this case with a brief review of the literature.

Inverted papillomas are benign but invasive tumors with malignant potential characterized by a high recurrence rate. Although most cases arise from the nasal wall and paranasal sinuses, inverted papillomas originating from the nasolacrimal system have been rarely reported. We describe a rare case of an inverted papilloma in the left nasal cavity, which originated from the lacrimal sac in a 40-year-old female who had a medical history of endoscopic dacryocystorhinostomy at the department of ophthalmology. At first, it was believed to be an inverted papilloma simply occurring in the nasal cavity, but after several recurrences, it was found to originate from the lacrimal sac. All intranasal lesions and the involved lacrimal sac were removed through cooperative surgery between department of otolaryngology and ophthalmology. This case illustrates the importance of including nasolacrimal system in differentiating the origin of inverted papilloma.

Cognitive behavioral therapy, first introduced by Beck in the 1950s to treat depression by integrating cognitive and behavioral therapies, is now an established psychotherapy technique used to treat insomnia, chronic pain, and anxiety. Currently, cognitive behavioral therapy is widely used to treat tinnitus in European countries, and the efficacy and safety of the treatment have been proven through randomized clinical trials and meta-analyses. Although interest in cognitive behavioral therapy for tinnitus is increasing in Korea, there are limited reports. Because many studies so far have targeted patients in Western countries, it is difficult to apply the same to domestic patients due to cultural and linguistic differences, the absence of standardized guidelines, and limitations in clinic hours. We experienced various cases in which tinnitus was effectively treated simultaneously with pharmacotherapy and cognitive behavioral therapy, so here we report an introduction to the program along with a literature review. Cognitive behavioral therapy was performed as a 4-week program in our hospital, and progress was evaluated through Visual Analogue Scales (VAS) and tinnitus handicap inventory (THI). After each weekly 20-minute individual counseling session, a take-home writing task was given to the patient. The main goal was to guide the patient to discover and correct automatic thoughts related to their tinnitus symptoms. This paper aimed to introduce a specific scheme on how to perform cognitive behavioral therapy for domestic tinnitus patients.

OBJECTIVE: To investigate the mechanisms involved in the mRNA expressions of hCG, LH/CG receptor and in hormone secretion in the trophoblast of normal and abnormal early pregnancy. METHODS: hCG, free Beta-hCG, and progesterone concentrations were measured in serum and the mRNA expressions of alpha,Beta-hCG and LH/CG receptor were measured in the placental trophoblast of 22 spontaneous abortion patients (spontaneous abortion group), 20 normal pregnancy women (normal pregnancy group) and 6 hydatidiform mole patients (hydatidiform mole group). RESULTS: 1. Mean values of serum hCG and free Beta-hCG concentrations were the lowest in spontaneous abortion group (46343.63+/-40404.18 mIU/ml, p<0.001; 31.34+/-61.57 mIU/ml, p<0.01 respectively) among the three groups. Mean progesterone concentration was the lowest in spontaneous abortion group (11.84+/-7.60 ng/ml, p<0.01), too.2. The expression levels of alpha,Beta-hCG were the highest in spontaneous abortion group (4.64+/-5.47, p=0.015; 4.57+/-4.42 p=0.002 respectively). The expression levels of LH/CG receptor were not different statistically among the three groups and they were high at the 5th week of gestation, reaching nadir at the 10th week of gestation when the concentrations of serum hCG showed peak values in normal pregnancy group.3. The correlations between serum hCG and progesterone concentrations were positive in both spontaneous abortion (r=0.827, p<0.001) and normal pregnancy (r=0.438, p=0.054) group. Though they were not significant statistically, the correlations between progesterone concentrations and the levels of alpha,Beta-hCG expressions were negative in both spontaneous abortion (r=-0.237, p=0.289; r=-0.211, p=0.347) and normal pregnancy (r=-0.270, p=0.250; r=-0.235, p=0.318) group. In hydatidiform mole group, the correlation between progesterone concentrations and the levels of Beta-hCG expression was positive (r=0.968, p=0.002). CONCLUSION: Our results suggest that the mechanisms involved in the secretion of hCG, progesterone and the expression of alpha,Beta-hCG, LH/CG receptor be normal in spontaneous abortion as in normal pregnancy and in the both groups, hCG stimulate the secretion of progesterone by autocrine function and control the secretion of itself, through the suppression of the expressions of alpha,Beta-hCG and LH/CG receptors. So the cause of spontaneous abortion in early pregnancy may be not placental dysfunction but the defect of embryo itself with poor placental growth.
