BACKGROUND: Chromosomal abnormalities are confirmed as one of the frequent causes of male infertility. The microdeletion of the azoospermia factor (AZF) region in the Y chromosome was discovered as another frequent genetic cause associated with male infertility. The aim of this study was to evaluate the frequency and type of chromosomal abnormalities and Y chromosome microdeletions in Korean infertile men. METHODS: A total of 846 infertile men with azoospermia and severe oligozoospermia were included for genetic screening. Cytogenetic analyses using G-banding and screening for Y chromosome microdeletions by multiplex PCR for AZF genes were performed. RESULTS: Chromosomal abnormalities were detected in 112 infertile men (13.2%). Of these, Klinefelter's syndrome was the most common (55.4%, 62/112), followed by balanced translocation including translocation between sex chromosome and autosome (14.3%), Yq deletion (13.4%), X/XY mosaicism with Yq deletion (12.5%), and XX male (4.5%). The overall prevalence of Y chromosome microdeletions was 9.2% (78/846). Most microdeletions were in the AZFc region (51.3%) with a low incidence in AZFa (7.7 %) and AZFb (6.4 %). Combined deletions involving the AZFbc and AZFabc regions were detected in 26.9 % and 7.7 % of men, respectively. Among the infertile men with Y chromosome microdeletions, the incidence of chromosomal abnormality was 25.6% (20/78). CONCLUSIONS: There was a high incidence (20.1%) of chromosomal abnormalities and Y chromosome microdeletions in Korean infertile men. These findings strongly suggest that genetic screening for chromosomal abnormalities and Y chromosome microdeletions should be performed, and genetic counseling should be provided before starting assisted reproductive techniques.

In case of loss of many teeth due to dental caries or periodontal disease, improvement of masticatory function and aesthetics can be obtained through implant treatment. However, if the patient does not have a normal intercondylar relationship, it is difficult to achieve an ideal occlusal relationship with only prosthetic treatment. In particular, oral reconstruction with orthodontic treatment or orthognathic surgery is necessary for patients with mandibular prognathism. However, if the posterior occlusion collapses due to severe caries or periodontal disease, orthognathic surgery may be difficult. The occlusal vertical stop is very important for the stability of the mandibular position during occlusal reconstruction through orthognathic surgery. The patient in this case had posterior occlusion collapsed due to the caries of a large number of posterior teeth, and showed mandibular prognathism and long face. We planned a full arch restoration with orthognathic surgery and extracted the hopeless teeth. To secure the vertical stop required for orthognathic surgery, the implant was placed before surgery. After the orthognathic surgery and the final prosthesis application, the results were satisfactory for the improvement of the aesthetics and the restoration of the masticatory function.

Atopic dermatitis (AD) is an inflammatory skin condition accompanied by symptoms such as edema and hemorrhage. Kimchi is a traditional fermented Korean dish consisting of various probiotics. In this study, the therapeutic effect of Lactobacillus plantarum CJLP55 isolated from Kimchi was studied in AD-induced mice. Orally administered Lactobacillus strain, CJLP55, suppressed AD symptoms and high serum IgE levels. CJLP55 administration reduced the thickness of the epidermis, infiltration of mast cells and eosinophils into the skin lesion, enlargement of axillary lymph nodes, and increase in cell population in axillary lymph nodes. CJLP55 treatment decreased the production of type 2 cytokines, such as interleukin (IL)-4, IL-5, IL-10, IL-12, interferon (IFN)-γ, and IL-6,which were stimulated by house dust mite extracts, in the axillary lymph node cells. Orally administered CJLP55 exhibited a therapeutic effect on house dust mite-induced AD in NC/Nga mice after onset of the disease by altering immune cell activation. The Lactobacillus strain, CJLP55, isolated from Kimchi, suppressed AD. Our results suggest its possible use as a potential candidate for management of AD.

Sarcoidosis is a multisystem inflammatory disease of unknown etiology characterized by noncaseating epithelioid granuloma formation. Although the relationship between sarcoidosis and malignancy has been noted in recent decades, there are few case reports describing the concurrent diagnosis of sarcoidosis and malignancy. Herein, we describe a case of biopsy-proven splenic sarcoidosis mimicking metastasis at the time of ovarian adenocarcinoma. Imaging studies including positron-emission tomography-computed tomography were not useful for differentiating sarcoidosis from malignancy. Thus, our case highlights the importance of histopathological examination to rule out nonmalignant conditions before the diagnosis of metastatic disease is made.

BACKGROUND: This study examines the clinical and radiologic results of ceramic-on-ceramic total hip arthroplasties with regard to wear, osteolysis, and fracture of the ceramic after a minimum follow-up of six years. METHODS: We evaluated the results of a consecutive series of 148 primary ceramic-on-ceramic total hip arthroplasties that had been performed between May 2001 and October 2005 in 142 patients. The mean age was 57.2 years (range, 23 to 81 years). The mean follow-up period was 7.8 years (range, 6.1 to 10.1 years). Preoperative diagnosis was avascular necrosis in 77 hips (52%), degenerative arthritis in 36 hips (24.3%), femur neck fracture in 18 hips (12.2%), rheumatoid arthritis in 15 hips (10.1%), and septic hip sequelae in 2 hips (1.4%). Clinical results were evaluated with the Harris hip score, and the presence of postoperative groin or thigh pain. Radiologic analysis was done with special attention in terms of wear, periprosthetic osteolysis, and ceramic failures. RESULTS: The mean Harris hip score improved from 58.3 (range, 10 to 73) to 92.5 (range, 79 to 100) on the latest follow-up evaluation. At final follow-up, groin pain was found in 4 hips (2.7%), and thigh pain was found in 6 hips (4.1%). Radiologically, all femoral stems demonstrated stable fixations without loosening. Radiolucent lines were observed around the stem in 25 hips (16.9%), and around the cup in 4 hips (2.7%). Endosteal new bone formation was observed around the stem in 95 hips (64.2%) and around the cup in 88 hips (59.5%). No osteolysis was observed around the stem and cup. There were 2 hips (1.4%) of inclination changes of acetabular cup, 2 hips (1.4%) of hip dislocation, 1 hip (0.7%) of ceramic head fracture, and 1 hip (0.7%) of squeaking. The Kaplan-Meier survival rate of the prostheses was 98.1% at postoperative 7.8 years. CONCLUSIONS: The ceramic-on-ceramic total hip arthroplasty produced excellent clinical results and implant survival rates with no detectable osteolysis on a minimum six-year follow-up study. The ceramic-on-ceramic couplings could be a reasonable option of primary total hip arthroplasty for variable indications.

HbA1c was recently adopted as a reliable indicator for screening diabetes. This study investigated the ability of nutrition consultation to prevent diabetes in overweight women (BMI 23 kg/m2 or more) using HbA1c as an indicator. Twenty overweight and obese women (with HbA1c> or =5.7%) completed the 12-week nutritional study, with individual and personalized nutrition counseling performed every 2 weeks. The main study guidelines involved the following: 1) reducing the intake of high fat foods and alcohol, 2) consuming a large amount of vegetables, 3) reducing the intake of simple sugars and empty-calorie foods, and 4) increasing physical activity to > or =30 min/day. Anthropometric (height, weight, BMI, body muscle (kg), body fat (%), waist and hip circumference, blood pressure) and biochemical parameters (fasting blood sugar (FBS), HbA1c, lipid profiles, hs-CRP) were measured before and after the nutrition consultation. After 12 weeks, the HbA1c<5.7% group had significant decreases in BMI, WC, HC, WHR, HbA1c, hs-CRP and also dietary intake of energy (P<0.01), carbohydrates, lipids (P<0.01), proteins (P<0.01) and cholesterol was significantly decreased (P<0.05). In the HbA1c > or =5.7% group, HbA1c, TC, LDL, NON-HDL, hs-CRP and dietary intake of energy, carbohydrate, lipid, protein, and cholesterol significantly decreased (P<0.05). These results suggest that nutrition consultation effectively helps to prevent diabetes in overweight and obese women after applying HbA1c standards. Overall, the improvement in all markers measured suggest that HbA1c is a good indicator for blood glucose regulation, helping to prevent diabetes.

OBJECTIVE: This study was to change of pulp blood flow among maxillary and mandibular anterior tooth with mild crowding and adjacent teeth using Ultrasound Doppler graphy. METHODS: The change of pulp blood flow was measured three times using Ultrasound Doppler graphy; before the attachment of brackets, after 3 week, and after 6 week. The sample consists of 15 year old eighteen patients. RESULTS: Before the attachment of brackets, after 3 weeks, and after 6 weeks, there were no significant differences in the change of pulp blood flow in each part (maxilla and mandible) and each tooth according to period. In addition, to compare internal dangerousness of loss of the pulp vitality, when pulp blood flow is compared in each tooth before orthodontic treatment, there were no statistically significant differences in maxillary lateral incisor and mandibular canine but it showed low values in all measurement items (p > 0.05). CONCLUSIONS: Results of this study can be not only methodological preliminary data in further study such as tooth movement type of Ultrasound Doppler graphy and particular study considered the patient age, but also reference materials for the loss of pulp vitality in orthodontic treatment.

Condylar hyperplasia is a pathologic condition showing 3-dimensional skeletal hyperplasia of the mandible. The reason for condylar hyperplasia is not yet known, but the effects of hormone, trauma, infection, genetics, fetal condition, and hypervascularity are known as possible reasons. When we diagnose a patient as having condylar hyperplasia, it is important to decide if it is in progress or not. Treatment for facial asymmetry due to condylar hyperplasia are decided accordingly, including condylectomy, that is removal of growth site of the affected condyle, and conventional orthognathic surgery only or condylectomy with orthognathic surgery after the completion of growth. Therefore, it is important to determine the growth state of condylar hyperplasia in treatment stability. This is verified through bone scan and regular check-ups with 3D CT or PA cephalogram. This case report introduces an improved case of facial asymmetry with condylectomy together with orthognathic surgery.

Adnexal torsion is a disease occurring mostly in young fertile women that causes severe pain with necrosis of the adnexa requiring an emergency surgery. Because the symptoms and physical findings are similar to emergency diseases of adjacent organs such as appendicitis, diagnosis of adnexal torsion could be confused. Delayed diagnosis leads to delayed operation and for that reason adnexectomy is done more often than conservative management. Since prompt diagnosis is the sole way for preservation of the ovary and the salpinx, early diagnosis of adnexal torsion is essential. We experienced a case of a 16 year old female with torsion of the right adnexa who had the left adnexa previously removed due to torsion of the left adnexa. The case is presented with review of the literature.

BACKGROUND: We wanted to identify the presence of the estrogen receptor (ER) alpha in Sertoli cells and gain insight on the regulation of the ER alpha gene expression by testosterone in Sertoli cells. The transcriptional regulation of the ER alpha gene was investigated in primary Sertoli cell cultures by in situ hybridization and reverse transcription-polymerase chain reaction (RT-PCR). METHODS: Primary Sertoli cell culture was performed. The expression levels of ER alpha and ER beta mRNA in Sertoli cells were detected by Northern blot, RT-PCR, immunocytochemistry and in situ hybridization. RESULTS: The ovary, testis and epididymis showed a moderate to high expression of ER alpha while the prostate, ovary and LNCap cells showed the ER beta expression. ER alpha mRNA and protein were detected in the germ cells and Sertoli cells by in situ hybridization and immunocytochemistry. The level of ER alpha mRNA was gradually decreased in a time-dependent manner after testosterone treatment, and the changes of ER alpha mRNA were dependent on the concentration of testosterone. Androgen binding protein and testosterone-repressive prostate message-2 (TRPM-2) mRNA were reduced at 24 hour by estradiol, while the transferrin mRNA was not affected. ER alpha mRNA was strongly detectable in the testes of 7 days-old-rats, but it was gradually decreased from 14 to 21 days of age. The primary Sertoli cells also showed the same pattern. The ER alpha gene expression was also regulated by testosterone in the Sertoli cells prepared from the 14- and 21-day old rats. CONCLUSIONS: These results suggest that ER alpha is transcriptionally regulated by testosterone and it may play some role in the Sertoli cells.
