BACKGROUND: The consensus is that a bony Bankart lesion shorter than 25% of the length of glenoid does not affect the clinical result; hence, such lesions were often neglected. However, small bony Bankart lesions are associated with various types of capsulolabral lesions. METHODS: A total of 82 patients who had undergone arthroscopic capsulolabral lesion repair surgery for anterior shoulder dislocation were reviewed. The prevalence rates of early and late type of capsulolabral lesions were compared between a group of patients with and a group without small bony Bankart lesions. In addition, the types of accompanying capsulolabral lesion were analyzed according to the type of bony Bankart lesion. Finally, the clinical outcomes were evaluated (active range of motion, American Shoulder and Elbow Surgeons score and Rowe's score). RESULTS: Among the 13 patients who had small bony Bankart lesions, the prevalence rate of early and late type of capsulolabral lesions was 38.5% and 61.5%, respectively. Among the 69 patients without bony Bankart lesion, the prevalence rates of early and late type of capsulolabral lesions were 74% and 26%, respectively. Significantly worse clinical outcome was observed for the group of patients with both small bony Bankart lesions and late type of capsulolabral lesion. CONCLUSIONS: More severe type of small bony Bankart lesion appears to be associated with late type of capsulolabral lesion. The significantly worse clinical outcome for patients with both small bony Bankart lesion and late type of capsulolabral lesion indicates that small bony Bankart lesions cannot always be neglected.

In spite of technical advances in neuroradiology, neuroanesthesiology, and microneurosurgery, the treatment of giant aneurysms remains problematic. Between 1983 and 1995, the authors encountered 42 consecutive cases of giant aneurysms, and this study focuses on their clinical manifestations, management, and outcome. The patients' ages ranged from 5 to 73 years, with peak incidence in the sixth decade ; the male to female ratio was 12 : 30. The follow-up period was from 2 to 110(mean, 36) months. The most common presenting symptom was a mass effect found in 22 patients(52%), followed by subarachnoid hemorrhage in 16(38%). Thirty patients underwent a surgical or interventional radiological procedure, comprising direct neck clipping(n=13), proximal clipping(n=7), detachable balloon occlusion(n=4), wrapping(n=3), trapping(n=1), and partial clipping with thrombectomy(n=2). The mortality rate was 16.7% and the morbidity rate, 40% ; the most common postoperative complication was distal cerebral infarction. At the last follow-up, 22 patients(73%) were able to perform daily activities without assistance. In this clinical study, the authors reviewed general aspects of the treatment of giant aneurysms. In conclusion, treatment of giant aneurysms should-for best results-be tailored to patients' individual requirements, determined after thorough examination. Despite advanced neurosurgical techniques, morbidity and mortality rates remain high.

BACKGROUND: Although the wet earwax has been known to be related with the incidence of tinea versicolor, very little has been revealed on how they are correlated with each other. The incidence of Malassezia furfur, the etiological organism of tinea versicolor, and its population densities as yearst and mycelial form in the different types of earwax, the dry and the wet, have not been studied. METHODS: The type of earwax in 65 patients with tinea versicolor were classified into 2 types, dry and wet, by its appearence and the subjective complaints of the patients. The dry and wet cerumens were obtained from 142 and 49 individulas without tinea versicolor respectively. The cerumens were stained with 10% Parker ink-KOH solution. The incidence and its population densities of yeast and mycelial M. furfur in the wet cerumens were compared with those in the dry cerumens according to a new grading method using bacterial index(BI) of lepra bacilli. RESULTS: 1. Dry and wet earwax were observed in 58.5%(38 cases) and 41.5%(27 cases) of 65 patients respectively. 2. The incidence of yeast M. furfur in the dry and wet cerumens were 100% and 63.3%(31 of 49 cases) respectively, and that of mycelial M. furfur, 28.2%(40 of 142 cases) and 32.7%(16 of 49 cases) respectively. 3. The population densities(from 3+ to 6+) of yeast M. furfur in the dry and wet cerumens were ob served in 93.0%(132 of 142 cases) and 49.0%(24 of 40 cases), and those(3+) of mycelial M. furfur, 21.1%(30 of 142 cases) and 24.5%(12 of 49 cases) respectively. CONCLUSION: The incidence(41.5%) of wet earwax in tinea versicolor patients is significantly higher than that(0.8%) in The Korean control group. The ratio between the incidence of mycelial M. furfur and that of yeast M. furfur in the wet cerumens is higher than in the dry cerumens, and the ratio of population densities in the wet cerumens is also higher. These observations suggest that the skin surface conditions of the wet earwax group may be more suitable for yeast-mycelial transformation of M. furfur than those of the dry earwax group. The comparison of chemical compositions of the skin surface between dry and wet earwax groups is needed to elucidate the correlation between tinea versicolor and the types of earwax in the future.

Eczema herpeticum occurred in a patient with pemphigus foliaceus and esophageal cancer. The patient's initial skin lesions composed of large flaccid bullaes showed subcorneal bullae with typical acantholytic cells. Subsequent grouped small vesicles appeared widely on the erythematous base were diagnosed herpes simplex virus infection by Tzanck smear and histopathological findings. The patient died one week after the development of the widespread herpes virus infection.

The measurement of the relative X-ray abssorption coefficient (CT No.) and the size of the lesion on CT ishighly valuable in the diagnosis of the certain disease, guide to treatment planning, and follow-up of patientunder treatment. But as the CT is a synthetic image, CT No. and size displayed in CT are greatly influenced byvarious factors such as KVp, slice thickness, scan time, CT No. of the surrounding, geometry of lesion in gantry,window width(W.W) and window level(W.L) etc. The study was performed ot evaluate the accuracy and error range ofthe CT measurement, including CT No. and size affected by various conditons using phantom model designed byauthor., Author also propose the optimum window width and window level for measurement of real size on CT. Theresulsts are as follows; 1. The CT No. of the lesion increases as the CT N. of surround increase if the CT No. ofthe lesion is below-100 H.U., while the CT No. of the lesion decreases as the CT No. of surround increases if theCT No. of the lesion is above 900 H.U. 2. The CT No. increases as photon influx (mAs) during scan increases. The higher the CT No. of the lesion, the greater the degree of increases are. 3. If the CT No. of the lesion is greater than that of surround, the size of the lesion increases as window level decreases. The narrower the windowwidth, the larger the difference between the maximum and minimum value of measurement and the steeper the slope ofchange is. 4. The window width affects the size if the measured size is sufficiently different from the true size.5. The greater the difference between the CT No. of the lesion and that of surround, the greater the differencebetweeen the maximum and minimum value of measurement. and as the CT No. of surround increases, the differencebetween the minimum and maximum value also increases. 6.

A 12-year-old boy showed a slatecolored scaly patch on h; ight face for 2 months. Histopathologic findings showed basal vacuolations and dermal me arphages with only scanty lymphoid cells in the fat tissue layer. Besides the facial lesion, lesions of edematous localized erythema were noted on his right if and left buttock with similar mi rocopical findings. 6 months later the facial lesion was aggravated like a cellulitis, of which thc bevpsy findings were consistent with mycosis fungoides. The patient received chemotherapy aftei the diagonsis for one month before his termination. Because of the rarity of mycosis fungoides in childhood age and its un common cutaneous lesions, the case is reported.

Surgical treatment of posterior circulation aneurysms are still challenging to the neurosurgeons, requiring highly skilled hands. During the past 10 years, the senior author(DH Han) operated upon 64 posterior circulation aneurysms. The number of the basilar bifurcation aneurysms(BBAA) were 31(48%), the posterior cerebral artery aneurysms(PCEAA) 7, the superior cerebellar artery aneurysms(SCAA) 10, the anterior inferior cerebellar aneurysms(AICAA) 3, the vertebro-basilar junction aneurysms(VBJA) 2, the vertebral artery aneurysms(VAA) 5 and the posterior inferior cerebellar artery aneurysms(PICAA) 6. The surgical approaches for BBAA, SCAA and PCEAA(proxinal to P4) were pterional route in 41 aneurysms and subtemporal in 4. Modified pterional approach was suitable for most of such aneurysms. For lower basilar trunk aneurysms(AICAA and VBJA), both far lateral suboccipital craniectomy and petrosal presigmoid approach had been tried and the presigmoid one seemed to be the choice of approach. The authors achieved aneurysmal neck clipping in the 48(75%) aneurysms, wrapping in other 8 and proximal clipping in the other 8. The operative mortality and morbidity were 6% and 17% each, which were comparable to the other series. Concerning surgical complications, transient oculomotor palsies were most frequent(38%), followed by transient hemiparesis, thalamic infarction, status epilepticus and peripheral infarction of the parent-arterial territory.

To settle the controversy over the optimum management strategy for patients with poor-grade(Hunt-Hess grade IV and V) aneurysmal subarachnoid hemorrhage, the medical records of 50 patients admitted in poor Hunt-Hess grade have been examined retrospectively with literature review. Twelve patients underwent early surgery for aneurysmal neck clipping, and for the other patients, initial conservative management was done followed by delayed operation for 19 patients who showed stabilization or improvement of neurologic status. All patients were managed by active treatment(hypertensive, hypervolemic and hemodilutional therapy) after aneurysmal neck clipping. Initial findings such as better neurological condition(Hunt-Hess grade IV) and presence of intracerebral hemorrhage were indicators of good prognosis. Patients with intraventricular hemorrhage and uncontrollably increased intracranial pressure(>40 cm H20 after extraventricular drainage) resulted in severe morbidity or mortality. Regarding the timing of surgery, early intervention led to a better outcome with less morbidity(8% vs. 26%) compared with delaying operation, because of the lower incidence of rebleeding, reduced vasospasm and more effective management of delayed ischemia after surgery. The incidence of intraoperative premature rupture and mortality were not significantly influenced by the timing of surgery. It is concluded that, for poor-grade aneurysm patients without a definite evidence of irreversibility such as brainstem failure signs or uncontrollably increased intracranial pressure, early surgery followed by aggressive treatment to prevent cerebral vasospasm is the treatment of choice.

Surgical treatment of posterior circulation aneurysms are still challenging to the neurosurgeons, requiring highly skilled hands. Patients with intracranial aneurysms operated on from January 1984 to January 2003 have been reviewed retrospectively. During that period 104 patients with 110 posterior circulation aneurysms underwent operation in our institute. Among them 47 patients had 49 aneurysms at the basilar bifurcation. The posterior cerebral artery aneurysms (PCEAA) 11, the superior cerebellar artery aneurysms (SCAA) 18, the anterior inferior cerebellar aneurysms (AICAA) 6, the vertebral artery aneurysms (VAA) 8 and the posterior inferior cerebellar artery aneurysms (PICAA) 18. The surgical approaches for BBAA, SCAA and PCEAA (proximal to P4) were pterional route in 70 aneurysms and subtemporal in 4. Modified pterional approach was suitable for most of such aneurysms. For lower basilar trunk aneurysms (AICAA and VBJA), both far lateral suboccipital craniectomy and petrosal presigmoid approach had been tried and the presigmoid one seemed to be the choice of approach. The author achieved aneurysmal neck clipping in the 82 (73%) aneurysms, wrapping in other 15 and proximal clipping in the other 13. The operative mortality and morbidity were 6% and 17% each, which were comparable to the other series. Concerning surgical complications, transient oculomotor palsies were most frequent (38%), followed by transient hemiparesis, thalamic infarction, status epilepticus and peripheral infarction of the parent-arterial territory.
