Vancomycin-induced Linear IgA Bullous Dermatosis: A Case Report and Review of the Literature.

Linear IgA bullous dermatosis (LABD) is a rare autoimmune bullous disease that can either occur without any apparent cause or be induced by the administration of certain drugs, the most common of which is vancomycin. We present a case of a 45-year-old woman who was diagnosed with vancomycin-induced LABD by the presence of a characteristic linear band of IgA along the basement membrane zone on direct immunofluorescence microscopy. Our patient showed complete recovery after a 2-week period during which vancomycin administration was discontinued.

COMP-angiopoietin 1 Gene Transfer Enhances Cutaneous Wound Healing by Promoting Angiogenesis.

Background: Angiogenesis is crucial for wound healing and exogenous supplements of the angiogenic growth factors have been known to promote cutaneous wound healing. Angiopoietin (Ang) 1 is a recently discovered angiogenic factor and there have been few studies of its effect on cutaneous wound healing.

Objective: We examined the effect of Ang 1 on cutaneous wound healing.

Paroxetine for patients with undifferentiated somatoform disorder: A prospective, open-label, 8-week pilot study.

Background: Forty-eight percent of somatic symptoms encountered in the primary care setting are medically unexplained. Such symptoms have been associated with negative impact on quality of life and with functional impairment.

Objective: The aim of this study was to assess the potential utility and tolerability of paroxetine for the treatment of undifferentiated somatoform disorder (USD), using the 15-item Patient Health Questionnaire (PHQ-15) to assess the severity of somatic symptoms.

Effect of the dysbindin gene on antimanic agents in patients with bipolar I disorder.

Objective: We previously reported an association between dysbindin gene (DTNBP1) variants and bipolar I disorder (BID). This paper expands upon previous findings suggesting that DTNBP1 variants may play a role in the response to acute mood stabilizer treatment.

Methods: A total of 45 BID patients were treated with antimanic agents (lithium, valproate, or carbamazepine) for an average of 36.

Comparison of clinical results between heparin surface modified hydrophilic acrylic and hydrophobic acrylic intraocular lens.

Purpose: To compare the clinical results of heparin surface modified (HSM) hydrophilic acrylic intraocular lens (IOL) with those of hydrophobic acrylic IOL.

Methods: One hundred patients with cataract were randomized to receive one of acrylic foldable IOLs after phacoemulsification: HSM hydrophilic acrylic IOL (n=50) BioVue3 (BioVue, OII, Ontario, CA, USA) and hydrophobic acrylic IOL (n=50) Sensar (AR40e, AMO, Santa Ana, CA, USA). Bestcorrected visual acuity and refractive error were measured at 1 week, 2 months, 6 months and 12 months after surgery in both IOL groups.

Evaluating the nickel content in metal alloys and the threshold for nickel-induced allergic contact dermatitis.

Many patients are currently suffering from nickel (Ni)-induced allergic contact dermatitis (ACD). There have been few Korean studies dealing with the threshold of Ni-induced ACD and quantifying the total amount of Ni in the metal alloys. The aim of this study is to evaluate the amount of Ni leached from metal alloys and Ni contents in metal alloys, and to estimate the threshold of Ni-induced ACD.

Expression of Toll-like receptors in verruca and molluscum contagiosum.

Recent studies indicate that several Toll-like receptors (TLRs) are implicated in recognizing viral structures and instigating immune responses against viral infections. The aim of this study is to examine the expression of TLRs and proinflammatory cytokines in viral skin diseases such as verruca vulgaris (VV) and molluscum contagiosum (MC). Reverse transcription-polymerase chain reaction and immunostaining of skin samples were performed to determine the expression of specific antiviral and proinflammatory cytokines as well as 5 TLRs (TLR2, 3, 4, 7, and 9).

Usefulness of laryngeal phonation CT in the diagnosis of vocal cord paralysis.

Objective: The purpose of this study was to determine the effectiveness of laryngeal phonation CT for the diagnosis of vocal cord paralysis by examining the physiologic and functional changes in the larynx during vowel phonation in patients with vocal cord paralysis.

Subjects And Methods: For the control study, three healthy volunteers underwent laryngeal phonation CT while vocalizing the vowels /hee/, /ih/, and /ah/, and reconstructed coronal images of the larynx were obtained. After the control study, 28 patients with unilateral vocal cord paralysis underwent laryngeal phonation CT during /hee/ phonation, which was chosen as a most appropriate vowel for this purpose.

Comparative analysis of immunohistochemical markers with invasiveness and histologic differentiation in squamous cell carcinoma and basal cell carcinoma of the skin.

Background: This study evaluates several tumor-related markers to examine the expression pattern of markers according to the invasiveness and histopathologic differentiation of squamous cell carcinoma and basal cell carcinoma.

Methods: Ninety-four cases of squamous cell carcinoma and 108 cases of basal cell carcinoma using tissue array in order to determine correlations between the expression of Ki-67, p53, EGFR, CD44v6, MMP-1 and MMP-3, invasiveness and histologic differentiation. In order to determine invasiveness, we measured the depth of invasion in resected tissues.

Aripiprazole in the treatment of depressive and anxiety disorders: a review of current evidence.

Despite the availability of different classes of drugs for the treatment of depressive and anxiety disorders, there are a number of clinically significant unmet needs, such as a high prevalence of treatment resistance, partial response, subsyndromal symptomatology, recurrence and relapse. With the approval of atypical antipsychotics, which are associated with a lower adverse effect burden than typical antipsychotics, consideration of their off-label use for the treatment of affective disorders and various other psychiatric disorders has become a viable option. However, consideration should be given to the US FDA black box warning indicating that atypical antipsychotics may increase mortality risk, particularly in the elderly population with dementia-related psychosis.

MRI features of ovarian fibromas: emphasis on their relationship to the ovary.

Aim: To evaluate the magnetic resonance (MR) imaging features of ovarian fibromas, emphasizing the presence and shape of the ovary on the same side of the fibroma.

Materials And Methods: MR images from 23 patients with 24 histologically proven ovarian fibromas were reviewed by two radiologists. Eleven were pre-menopausal and 12 were postmenopausal.

Visualization and localization of rheumatoid knee synovitis with FDG-PET/CT images.

We annually evaluated (18)F-fluorodeoxyglucose-positron emission tomography/ computed tomography (FDG-PET/CT) scans for three consecutive years in a patient with rheumatoid arthritis. The inflammatory activity of the rheumatoid synovium was visualized in coronal and transverse sections by FDG-PET/CT. The extent and area of the synovial inflammation was relatively well delineated, and this technique was more informative in detecting inflammation than were conventional X-rays.

Single-nucleotide polymorphisms (SNPs) and haplotype analysis in vascular endothelial growth factor (VEGF) gene in the patients with Parkinson disease and lung cancer.

The epidemiologic data on smoking in association with Parkinson disease (PD) is puzzling. A lower incidence of smoking-related malignancies, especially lung cancer, has been reported by several studies in the patients with PD. In this study, we investigated polymorphic variations in the vascular endothelial growth factor (VEGF) gene, which has been proposed having a pivotal role in progressive damage of nigral dopaminergic neurons, between Korean patients with 188 PD and 321 lung cancer patients.

A Case of Malignant Peripheral Sheath Tumor Arising from Neurofibromatosis Type 1.

Malignant peripheral nerve sheath tumor (MPNST) is a term encompassing tumors previously diagnosed as malignant schwannoma, malignant neurilemmoma, neurogenic sarcoma, and neurofibrosarcoma The occurrence rate of MPNST in neurofibromatosis type 1 patients is known to be about 4.6%. Tumors occurring in this particular group have a worse prognosis in that they occur at an earlier age, are more centrally located, tend to be of a larger size and show more metastases and recurrences.

Thy1-positive bone marrow stem cells express liver-specific genes in vitro and can mature into hepatocytes in vivo.

The bone marrow contains stem cells that have the potential to differentiate into a variety of organ-specific mature cells, including the liver and the pancreas. Recently, the origin of hepatic progenitors and hepatocytes was identified to be the bone marrow. However, evidence that describes which cells, among all bone marrow cells, differentiate into hepatocytes, has not yet been presented.

Association analysis of heat shock protein 70 gene polymorphisms in schizophrenia.

Objectives: Heat shock proteins (HSPs) are a promising candidate gene in schizophrenia as they are believed to play a protective role in the central nervous system. An alteration in the titers of antibodies to the HSPs in schizophrenia patients has been suggested. Association between the three polymorphisms of HSP70-1 (HSPA1A), HSP70-hom (HSPA1L) and HSP70-2 (HSPA1B) and schizophrenia has been reported.

Does minocycline have antidepressant effect?

Only one-third of patients undergoing monotherapy with an antidepressant achieve remission of their depressive symptoms and gain functional recovery. Therefore, further exploration of antidepressant mechanisms of action is important in order to facilitate the development of antidepressants with new modes of action. Preclinical and clinical studies have demonstrated that major depression is associated with impaired inflammatory responses and deficient neuroprotection.

Is totally laparoscopic gastrectomy less invasive than laparoscopy-assisted gastrectomy?: prospective, multicenter study.

Background: Laparoscopic surgery has been adopted for the treatment of gastric cancer, and many reports have confirmed its favorable outcomes. Most surgeons prefer to laparoscopy-assisted gastrectomy using minilaparotomy rather than totally laparoscopic procedures because of technical difficulties of intracorporeal anastomosis. We conducted this study to compare laparoscopy-assisted distal gastrectomy with totally laparoscopic distal gastrectomy.

Application of three-dimensional computed tomography for the rheumatoid wrist.

Recent technical advances in computed tomography (CT) and the introduction of three-dimensional (3D) image reconstruction through computer systems make distinct visualization of tiny defects in the hand and wrist a feasible task. Three wrists from three patients -- two of whom are patients with rheumatoid arthritis and one with osteoarthritis -- were evaluated by 3D CT. Images were obtained with a multidetector-row CT scanner.

Oral administration of type-II collagen suppresses IL-17-associated RANKL expression of CD4+ T cells in collagen-induced arthritis.

The receptor activator of nuclear factor kappaB ligand (RANKL) is an osteoclastogenic mediator, which is mainly expressed by stromal cells and osteoblast. However, T cells can also be an important provider for RANKL in special condition such as autoimmune arthritis. We examined the RANKL expression of hyporesponsive CD4+ T cells induced by oral feeding with type II collagen in collagen-induced arthritis (CIA) mice.

Changes in CT appearance of intrathoracic gossypiboma over 10 years.

An intrathoracic gossypiboma is a rare condition. Moreover, intrathoracic gossypibomas with intrapulmonary location are extremely rare and only a few cases of intrapulmonary gossypiboma have been published. Usually gossypiboma has the characteristic CT appearance of a soft tissue mass with high attenuation, air bubbles and a whirl-like pattern, but its radiological manifestations may be variable according to the location and chronicity of the sponge.

Evaluation of the soft and hard tissue changes after anterior segmental osteotomy on the maxilla and mandible.

Purpose: The purpose of this study was to determine the relationship between the changes of soft and hard tissues after modified anterior segmental osteotomy on the maxilla and mandible and to evaluate unintended facial changes using cephalometric and photometric analyses.

Materials And Methods: The subjects included 29 women and 1 man (22 to 50 years of age) who were diagnosed as bialveolar or bimaxillary protrusion and underwent modified anterior segmental osteotomy on the maxilla and mandible. Lateral cephalograms and lateral and frontal photographs taken preoperatively and postoperatively were analyzed.

Prognostic factors affecting the clinical outcome of adenoid cystic carcinoma of the head and neck.

Background: Adenoid cystic carcinoma (ACC) is an uncommon tumor, constituting approximately 10% of all head and neck tumors. Classically, ACC has been described as a tumor with indolent, but persistent and recurrent, growth and late onset of metastases, leading eventually to death. This study assessed the prognostic factors affecting the clinical outcome in patients with ACC in the head and neck region.
