Lupoid leishmaniasis is a unique form of cutaneous leishmaniasis characterized by unusual clinical features and a chronic relapsing course, mostly caused by infection with Leishmania tropica. In this clinical form, 1-2 yr after healing of the acute lesion, new papules and nodules appear at the margin of the remaining scar. Herein, we describe a case of this clinical form that was resistant to 2 courses of treatments: systemic glucantime and then a combination therapy with allopurinol and systemic glucantime. However, marked improvement was seen after a combination therapy with topical trichloroacetic acid solution (50%) and systemic glucantime, and there were no signs of recurrence after 1 yr of follow-up.

The restorative treatment using titanium implants has become a standard procedures in everyday clinical practice. However, there are several concerns about the use of titanium as a materials. Above all, the grayish metal color provokes esthetic problems when the soft tissue around the implants is not optimal. Recently, zirconia has been emerging as an alternative to titanium due to its white color and superior physicochemical properties. In this paper, the current findings about zirconia implants was reviewed based on the results from animal and clinical experiments. In addition, the immediate implantation protocols using the natural tooth form zirconia implants was introduced as a novel procedures and future perspectives were discussed.

The purpose of the present study was to examine the relationship between the form of the clinical crowns in the maxillary anterior segment and the clinical feature of gingiva such as morphological characteristics and the gingival thickness. Fifty periodontally healthy subjects were clinically examined regarding the probing depth, the thickness of the free gingiva, and the width of the keratinized gingiva. From study models of the maxillary anterior region, the width at cervical third(CW) and the length(CL) of the clinical crown, the papillary height, and the gingival angle of the 6 anterior teeth were measured. Each tooth was classified into 4 groups (longnarrow, NL; narrow, N; wide, W; short-wide, WS) according to CW/CL ratio and all the data were compared between groups NL and WS using independent t-test. Stepwise multiple regression analysis was performed for each tooth region with the gingival thickness at the level of sulcus bottom, the width of keratinized gingiva, and gingival angle as the dependent variables. As the results, the NL group of the upper anterior teeth displayed, higher papilla height, and narrower keratinized gingiva, more acute gingival angle resulting in pronounced "scalloped" contour of the gingival margin, compared to the WS group. There was no significant difference between groups NL and WS with respect to probing depth and the gingival thickness. The regression analyses demonstrated that the gingival thickness in central incisors was significantly associated to the mesio-distal width and bucco-lingual width of the crown, and labial probing depth. The width of keratinized gingiva was significantly associated with labial probing depth in central incisors and with proximal probing depth and gingival angle in lateral incisors, and with labial and proximal probing depth, and gingival angle in canines. The gingival angle was significantly associated with papillary height and CW/CL ratio and additionally with proximal probing depth in central incisors, with the width of keratinized gingiva in lateral incisors, and with labial probing depth and the width of keratinized gingiva in canines. These results indicate that the form of clinical crown in upper anterior region could influence the clinical feature of gingiva and the influencing factors might be different according to the tooth region.

To clarify the clinical spectrum of non-oliguric acute renal failure, we undertook a retrospective study of 16 cases of acute renal failure following trauma and surgery, 6 of whom were non-oliguric throughout their periods of azotemia. With the clinical symptoms, BUN, creatinine and some urinary diagnostic indexes, we analyzed the differences between non-oliguric and oliguric renal failure. And the results were: 1. The nonoliguric form [10 cases] was more common than oliguric [6 cases], especially post-traumatic failure. 2. The both types belonged to parenchymal renal failure by the U/P UN ratio and urinary Na concentration [Vertal, 1967]. 3. The non-oliguric form was lesser severe in urinary diagnostic indexes and clinically. The non-oliguric renal failure has better clinical course and prognosis, the failure to diagnose it is as dangerous as the failure oliguric renal failure.

Objective : Stent-assisted coil embolization (SAC) is commonly used for treating wide-neck intracranial aneurysms. In this study, we aimed to assess the clinical safety and efficacy of the NeuroForm Atlas Stent during SAC of intracranial aneurysms. Methods : We retrospectively analyzed data from patients with ruptured and unruptured cerebral aneurysms, who underwent SAC using the NeuroForm Atlas between February 2018 and July 2018. Favorable clinical outcomes and degree of aneurysm occlusion were defined as a modified Rankin scale score of ≤2 and a Raymond-Roy occlusion classification (RROC) class I/II during the immediate postoperative period and at the 6-month follow-up, respectively. Results : Thirty-one consecutive patients with 33 cases, including 11 ruptured and 22 unruptured cases were treated via NeuroForm Atlas SAC. Among the 22 unruptured cases with 24 unruptured aneurysms had favorable clinical outcome. Complete occlusion (RROC I) was achieved in 16 aneurysms (66.7%), while neck remnants (RROC II) were observed in six aneurysms (25%). Among the 11 patients with ruptured aneurysms, two died due to re-bleeding and diabetic ketoacidosis. In ruptured cases, RROC I was observed in eight (72.7%) and RROC II was observed in three cases (27.3%). At the 6-month follow-up, no clinical events were observed in the 22 unruptured cases. In the ruptured nine cases, five patients recovered without neurologic deficits, while four experienced unfavorable outcomes at 6 months. Of the 29 aneurysms examined via angiography at the 6-month follow-up, 19 (65.5%) were RROC I, eight (27.6%) were RROC II and two (6.9%) were RROC III. There were no procedure-related hemorrhagic complications. Conclusion : In this study, we found that stent-assisted coil embolization with NeuroForm Atlas stent may be safe and effective in the treatment of wide-neck intracranial aneurysms. NeuroForm Atlas SAC is feasible for the treatment of both ruptured and unruptured wide-neck aneurysms.

In order to provide appropriate decision supports in medical domain, it is required that clinical knowledge should be implemented in a computable form and integrated with hospital information systems. Healthcare organizations are increasingly adopting tools that provide decision support functions to improve patient outcomes and reduce medical errors. This paper proposes a process centric clinical decision support system based on medical knowledge. The proposed system consists of three major parts - CPG (Clinical Practice Guideline) repository, service pool, and decision support module. The decision support module interprets knowledge base generated by the CPG and service part and then generates a personalized and patient centered clinical process satisfying specific requirements of an individual patient during the entire treatment in hospitals. The proposed system helps health professionals to select appropriate clinical procedures according to the circumstances of each patient resulting in improving the quality of care and reducing medical errors.

Castleman's disease is an atypical lymphoproliferative disorder of unknown origin. It has three histologic variants(hyaline vascular, plasma-cell, and mixed) and two clinical types(localized and multicentric). Some sufferers have constitutional symptoms and laboratory abnormalities such as anemia, hypoalbuminemia, hypergammaglobulinemia, and elevated erythrocyte sedimentation rate. The localized form is cured by complete surgical excision whereas the multicentric form is managed by prednisone and other immunosuppressor drugs. The prognosis of the multicentric form is worse than the localized form since malignancies and severe infections may lead to a rapidly fatal outcome. Castleman's disease has been rarely reported at pediatric age in Korea. We experienced two cases of Castleman's disease detected at 3 and 5 years of age. They were presented with painless enlargement of submandibulars and axillary lymph nodes but had no associated symptoms. The lesions were excised and diagnosed as Castleman's disease, and no recurrence was noted during follow-up periods.

Tablet splitting is used in pharmacy practice to adjust the dose to be administered. However, it also causes several problems such as undesirable effect for sustained release or enteric-coated dosage form, inaccuracy of dose, and pharmacist's safety by splitting hazardous drugs. This study investigated the current status of oral dosage form splitting for patients older than 19 years by analyzing Korea National Health Insurance Claims Database. Out of oral solid drugs prescribed (N=1,486,584) 9.8% of them included tablets (or capsules) split. There were some splitting cases even in sustained release (4.9%), enteric-coated forms (1.3%) and hazardous drugs (2.7%) that were selected by NIOSH (The National Institute for Occupational Safety and Health). The most frequently split drugs were antihistamines, neuropsychotics and steroids. In case of digoxin and warfarin, unit doses in a domestic market were not diverse compared to foreign markets. Guidelines for splitting oral solid dosage forms, approval of diverse doses and conducting dose-response studies for the commonly splitting ingredients on Korean people are needed for the saff and effective use of oral solid drugs.
