PURPOSE: To evaluate the clinical outcomes, complications and surgically induced astigmatism (SIA) after scleral fixation in patients with intraocular lens (IOL) or crystalline lens dislocation. METHODS: The present study retrospectively investigated the postoperative best corrected visual acuity (BCVA), refractory change, corneal astigmatism, clinical outcomes, and influencing factors of SIA in 57 eyes of 55 patients with a follow-up of 6 months after the IOL scleral fixation. RESULTS: In comparison of preoperative and postoperative 6 months, BCVA, spherical equivalent and astigmatism were significantly improved but corneal astigmatism was not and SIA (diopter, D) improved from 2.10 +/- 1.88 D to 0.86 +/- 0.73 D (p = 0.002). 4 eyes having redislocation were repositioned and 4 eyes having tilted IOL, 6 eyes having elevated intraocular pressure, 3 eyes having exposure scleral knots, 1 eye having endophthalmitis, and 1 eye showing macular edema were observed. At postoperative 3 months, the SIA of a large incision size (>3 mm) and small incision size (< or =3 mm) was significantly differented (p = 0.041). According to the location of scleral fixation, SIA at postoperative 1 month was significantly different but, was not different at postoperative 6 months. CONCLUSIONS: Surgical management of dislocated IOLs or crystalline lens resulted in significant improvement of visual acuity and absence of influencing SIA factors. However, location of scleral fixation and small incision size influenced corneal astigmatism.

BACKGROUND: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. METHODS: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index (MEPI). RESULTS: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final follow-up (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. CONCLUSIONS: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

BACKGROUND: Our study aimed to make a comparative analysis of clinical outcomes of arthroscopic decompression for rotator cuff calcific tendinitis by location of calcific deposits and by its size. METHODS: We enrolled a total of 38 patients, comprising 39 affected shoulders, who underwent arthroscopic decompression for calcific tendinitis. As our clinical scores, we evaluated the UCLA, the ASES, and the VAS scores and analyzed them by calcific location, by calcific deposit size, by the presence or absence of calcific remnants, and by whether concomitant cuff repair was performed. RESULTS: The clinical scores of those whose calcific deposit had an area greater than 77.0 mm2 and of those whose calcific deposit had an area smaller than 77.0 mm2 did not significantly differ (p=0.21 in ASES; p=0.19 in UCLA; p=0.17 in VAS). Nor did the clinical scores significantly differ with respect to the location of calcification (p=0.23). Further, the clinical scores did not significantly differ between those who had calcific remnants and those who did not and between those who received additional cuff repair and those who did not. CONCLUSIONS: We found that the clinical outcomes after arthroscopic decompression of calcific tendinitis were not significantly associated with the cuff tendon in which the calcium deposits are found; the location of the calcium deposits in the supraspinatus tendon (if found in this tendon); the size of calcific deposits; the presence of calcific remnants; and concomitant cuff repairs.

Malignant tumors of the breast which contain stromal osteoclast-like, multinucleated giant cells are a rare entity of yet unknown clinical significance. These benign multinucleated giant cells are known to occur mostly in areas of prominent angiogenesis and in close association with tumor cells. Supplementary immunohistochemical and electronmicroscopic examinations indicate that the multinucleated giant cells are of histiocytic origin. We report on a case of infiltrating ductal carcinoma with stromal osteoclast-like multinucleated giant cells occurring in the right breast of a 37 year-old woman. Grossly, the tumor was characterized by a well-circumscribed dark brown, solid firm mass. Microscopically, multinucleated giant cells were found in the stroma intermingled with malignant tumor cells. The stroma showed only a small amount of mononuclear cell infiltration and a moderate degree of vascular proliferation. Immunohistochemical stains revealed the tumor cells to be positive for carcinoembryonic antigen, epithelial membrane antigen and cytokeratin while the multinucleated giant cells were positive for vimentin, CD68 and negative for all other stains tested. Ultrastructurally the multinucleated giant cells differed from tumor cells by having abundant cytoplasmic organelles such as rough endoplasmic reticulum, lysosomes, ribosomes, and vesicles but lacking desmosomes or other types of intercellular junctions. Other characteristic features of multinucleated giant cells included, indented nuclei and prominent cytoplasmic process.

OBJECTIVES: A field investigation was done to identify the level of epidemic and to evaluate the infection route of Salmonellosis occurred in a baby's first birthday banquet in Jeju Island. METHODS: Among participants in the banquet given on a baby's first birthday, persons showing gastrointestinal symptoms were conducted by the structured questionnaire and stool culture. The symptomless persons were also surveyed by self-responded structured questionnaire. The causal relationship between food items and gastrointestinal symptoms was proved by odds ratio and Wilcoxon rank-sum test. RESULTS: Salmonella london was identified in the stools of 12 subjects among 20 participants showing gastrointestinal symptoms, as well as in the boiled pork hock. CONCLUSIONS: This outbreak event is thought to happen after participants took the boiled pork hock that contaminated with S almonella london during the storage process.

BACKGROUND: Many investigators have advocated neural and especially regional sympathetic blockade for acute herpe. zoster pain. Some believe that nerve blocks not only relieve acute pain but also, if given early in the course of clinical disease, prevent progression to postherpetic neuralgia. OBJECTIVE: The purpose of this study was to evaluate the preventive effect of sympathetic blockade on herpes zoster METHODS: Fifteen patients with herpes zoster were treated with sympathetic blocks according to the severity of pain. RESULTS: The total score of pain degree decreased from 3.4 to 1.1 with sympathetic blocks in 15 patients in 2 months. Sympathetic blocks prevented or relieved postherpetic neuralgia in more than 90% of patients treated within 2 weeks of the onset of the acute phase of the disease and in more than 85% of patients over 60. CONCLUSION: Sympathetic blocks are effective in preventing postherpetic neuralgia if applied soon after the onset of the acute phase of herpes zoster.

BACKGROUND: Night shift work induces physiological and psychological stress by altering sleep and biological rhythms and is associated with hypertension, diabetes, obesity, and cardiovascular diseases. Few studies have been conducted on the control of hypertension and diabetes. This study aimed to examine the effect of night shift work on the control rate of hypertension and diabetes. METHODS: Subjects comprised workers aged 20–65 years who underwent specific health examination at a single facility in seven different affiliated examination centers from 1 January to 31 December 2016. Workers were categorised into day workers and night shift workers. Demographic and medical history were taken, and physical examination was done. Blood pressure (BP) and fasting glucose were measured. The control rate of each disease was evaluated based on treatment goals presented in the treatment guidelines of the Korean Society of Hypertension and the Korean Diabetes Association (systolic BP < 140 mmHg and diastolic BP < 90 mmHg; fasting glucose ≤ 130 mg/dL). RESULTS: Among 631,418 subjects, 11.2% (70,450) were night shift workers. Of whom 6.1% (4,319) were taking antihypertensive medication and 2.5% (1,775) were taking diabetes medication. Among patients taking antihypertensive medications, the proportion of those whose BP was controlled to suit treatment goals was 81.7% (26,635) of day workers and 77.4% (3,343) of night shift workers, which was significantly different (p < 0.001). Among patients taking diabetes medications, the proportion of those whose blood glucose was controlled to suit treatment goals was 37.4% (4,489) of day workers and 36.5% (647) of night shift workers, but the difference was not significant. The control rates for patients taking antihypertensive medications (odds ratio [OR]: 0.74, 95% confidence interval [CI]: 0.68–0.80) were lower among night shift workers than day workers with adjustment for age, sex, smoking history, alcohol consumption, exercise, and obesity. However, there were no differences in control rates for patients taking diabetes medications (OR: 0.99, 95% CI: 0.87–1.10) between day workers and night shift workers. CONCLUSIONS: Night shift work can have an effect on the uncontrolled BP in workers taking antihypertensive medications. Therefore, additional efforts for disease control are necessary for night shift workers with hypertension.

Psoriasis vulgaris is one of the most common skin diseases in the world, which is recognized as an autoimmune disease that is caused by genetic and environmental factors. Plaque, guttate, pustular form, and psoriatic erythroderma are known as classical feature of psoriasis with tendency as generalized or sporadic appearance. There are some cases of uncommon forms in the shape and distribution, as nevoid and linear psoriasis. Linear psoriasis is a rare entity and thought as a variant of psoriasis, but its existence is still in debate. Herein, we report an interesting case of 19-year old Korean man with psoriasis, occurring on the right arm, following the line of Blaschko in a linear form.

We experienced a case of lumbar epidural lipomatosis patient who had been treated with several epidural steroid injection for the management of lower back pain. This 67-years-old man, complained of lower back pain and radiating paresthetic pain to the dorsum of left foot. Epidural lipomatosis is a rare condition of focal or multiple deposition of excessive adipose tissue in epidural space. Since excessive deposited adipose tissue compresses the spinal cord or spinal root, patients complaint the atypical low back pain and low extremity radiculopathy which mimics the symptoms of spinal stenosis or herniated nucleus pulposus. In managing of lower back pain patient, especially who had been treated with steroid previously, we should consider that epidural lipomatois would be one of the cause.

Lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large cell lymphoma (ALCL) are grouped under the category of cutaneous T-cell lymphomas as CD30+ lymphoproliferative disorders. Though LyP is clinically characterized by chronic recurrent papulonodular cutaneous lesions, it shows malignant features on the histologic findings. LyP is associated with lymphomas, including primary cutaneous ALCL, mycosis fungoides and other lymphoproliferative disorders. A few cases of LyP related to ALCL have been reported in Korea. We report here on an interesting case of primary cutaneous ALCL that developed in succession after LyP in a 38-year-old female.
