We report a case of trichorrhexis nodosa in a 27-year-old male. Scanning electron microscopic findings reveals those of typical trichorrhexis nodosa nodal swelling of affected hair showed longitudinal fissures and fractures in the cortex. A paintbrush effect was noted at the site of fracture. Simple avoidance of trauma gave some regrowth of hairs.

Dermoid cysts develop from sequestration of epithelium along lines of embryonic fusion.The most common locations are the lateral third of the eyebrows, nose, and scalp. These cysts are located in the subcutis; they are often adherent to periosteum, and may invade or erode underlying bane. A 34-year-old female presented with a solitary, skin colored, dome-shaped, child fistsized, subcutaneous mass on her right occiput. At operation, keratinous material was discharged and tufts of hair projected from opening of the cyst wall.The base of the cyst was firmly adherent to periosteum and diffuse depression with focal deep erosions of the outer table of skull was found.

PURPOSE: Lymphoscintigraphy and sentinel node biopsy has become a standard method for detection of axillary lymph node metastasis in breast cancer patients, but the standard radiopharmaceutical was not prepared. About detection of axillary lymph node metastasis by lymphoscintigraphy and sentinel node biopsy in breast cancer patient, we compared the results of Tc-99m Tin-colloid and Tc-99m Phytate by subareolar injection. MATERIALS AND METHODS: This study included 382 breast cancer patients who were performed operation during 2001-2008. Three hundred forty nine patients was injected 0.8 ml of Tc-99m Tin-colloid (37-185 MBq) by subareolar injection. Thirty three patients was injected 0.8 ml of Tc-99m Phytate (37-185 MBq). Lymphoscintigraphy was performed in supine position and sentinel node localization was performed by hand-held gamma probe in operation. RESULT: Among 349 patients by Tc-99m Tin-colloid, 312 cases (89.4%) localized the sentinel node by lymphoscintigraphy, 304 cases (87.1%) localized by gamma probe. Among 33 patients by Tc-99m Phytate, 32 cases (97.0%) localized by lymphoscintigraphy, 33 cases (100%) localized by gamma probe. Detection rate by lymphoscintigraphy and gamma probe was superior for Tc-99m Phytate compared to that with Tc-99m Tin-colloid, with a statistically significant difference. (p<0.05, p<0.05) CONCLUSION: Tc-99m Phytate is a better choice for localization of sentinel node than Tc-99m Tin-colloid in breast cancer patients.

Acquired port-wine stain is rare. It mimics a congenital port-wine stain morphologically but the pattern of onset is acquired after birth. It represents a progressive ectasia of vessels located in the superficial vascular plexus. The exact mechanism is unknown but some reported cases have occurred after trauma. We herein report five cases of acquired port-wine stains and they were idiopathic in nature.

In the March 2009 edition of the Journal of Korean Neurosurgical Society, we published an article entitled "Unilateral Lumbosacral Facet Interlocking without Facet Fracture" (Volume 45, pages 182-184). Fig. 1B on page 183 was supposed to be printed in color, but it was printed in black by mistake. We apologize to the authors and readers of JKNS for any inconvenience.

Pneumorrhachis, which involves the entrapment of air or gas within the spinal canal, is a rare clinical entity, and the pathogenesis and etiologies of this uncommon entity are various and can present a diagnostic challenge. Usually, pneumorrhachis represents an asymptomatic epiphenomenon but it can produce symptoms associated with its underlying pathology. Here, we report a rare case of symptomatic epidural pneumorrhachis accompanying pneumothorax. Possible pathogenic mechanisms are discussed and a review of the literature is included.

BACKGROUND: During normal wound healing the formation of scars and fibrous tissue occurs, which consists largely of collagen fibril, but excessive fibrosis and scar formation become clinical problems. Collagen remodelling during scar formation is dependent on both continued collagen synthesis and collagen catabolism. Halofuginone, a plant alkaloid, is known to inhibit collagen type I synthesis at the transcriptional level. OBJECTIVE: The purposes of this study were to investigate the effects of topical application of halofuginone on the healing of wounds. METHOD: Topical solutions containing halofuginone of variable concentrations were applied on the full-thickness excisional wounds of hairless mice and 0.1% halofuginone ointments applied on the suture site of rats and the normal skin of hairless mice daily. In addition, we performed a one-time intradermal injection of 0.1% halofuginone solution on the normal skin of the hairless mice. We examined the collagen content of the skin of hairless mice and rats treated with halofuginone solutions and ointments during the healing process by performing hematoxylin-eosin and Masson's trichrome stains. We assessed, from time to time, the change in the full-thickness excisional wound size of hairless mice treated with halofuginone solutions of variable concentrations during the healing process and observed clinically the healing process of hairless mice with the full-thickness excisional wound. RESULT: 1. The wound size after daily application of 0.001% and 0.1% halofuginone solutions on the full-thickness excisional wounds of hairless mice decreased more slowly in comparison with the control group (p < 0.05).

BACKGROUND: The purpose of this article was to identify the risk factors related to development of hemodynamically significant cardiac arrythmias in patients with mechanical ventilation. METHODS AND RESULTS: Holter recording and echocardiogram were performed after 30 minutes of ventilator initiation in patients on mechanical ventilation(MV) owing to respiratory failure(RF) from various reasons. From 68 patients, hemodynamically significant cardiac arrythmias were detected in 18 patients(26.5%). Initial mean arterial pressure, maximal heart rate, and initial pH were identified as risk factors for hemodynamically significant cardiac arrythmias. Additionally, the patients with pressure-controlled ventilation as an initial ventilatory mode developed hemodynamically significant cardiac arrythmias less frequently than the patients with other modes(15.8% vs. 40%, p=0.03). In multivariate analysis, initial mean arterial pressure(<70mmHg, odds ratio[OR]:5.5;95% confidence interval[CI]:1.2 to 24.2, p=0.026), maximal heart rate(>120/min, OR:19.7;95% CI:2.0 to 190.0, p=0.01), and pressure-controlled ventilation(OR:0.13,95% CI:0.03 to 0.55, p=0.006) were associated with the development of hemodynamically significant cardiac arrhythmias. CONCLUSION: Theses findings suggest that during the early stages of mechanical ventilation with acute respiratory failure, hemodynamically significant cardiac arrhythmias are directly associated with tachycardia(>120/min), initial MAP(<70mmHg), and, inversely, the initial use of pressure-controlled ventilation.
