We performed a retrospective analysis of twenty-four consecutive hip arthroplasties (Total Hip Arthroplasty 18, Bipolar Arthroplasty 1, Cup revision 5) during which intraoperative frozen sections were analyzed to identify the occult active infection. We also reviewed the data such as laboratory findings (ESR, CRP), intraoperative culture, hip joint sonographic evaluation and permanent histologic section. Among the twenty-four patients those who received hip arthroplasties, 10 cases received revisional hip arthroplasties due to painful hip prosthesis loosening, 9 cases with infected hip prosthesis, 3 cases with infection after open reduction and internal fixation due to hip fracture and 2 cases with septic hip sequelae. Intraoperative frozen section had been obtained during staged revisional hip arthroplasties to determine the presence of active infection. We considered positive for infection if it shows more than 10 PML/HPF (Polymorphonuclear leukocyte /high power field) in at least 5 distinct microscopic fields from intraoperative tissue frozen section and postponed implantation of prosthesis. If it shows less than 5 PML/HPF, we performed revisional hip prosthesis implantation. We decided the implantation based on patient's condition, laboratory findings and intraoperative tissue conditions if it shows between 5 and 10 PML/HPF from intraoperative frozen section. At last follow up, 20 of 21 patients who had a revisional hip arthroplasties as below 10 PML/HPF from intraoperative frozen section remained free of infection (Specificity; 95%). We concluded that analysis of the intraoperative frozen sections is a reliable predictor as a guide to sepsis for the successful hip joint arthroplasties.

We reviewed 174 total hip arthroplasty (25 were revision procedure) and 65 bipolar hemiarthroplasty procedure followed by more than 6 months at Chungnam National University Hospital from July, 1992 to March, 1995. These were performed on 189 male and 50 female patients. We have followed up average 45.8 months and obtained following results; The dislocation rate is 3.76% (9 of 239 cases) and the dislocation rate of revision arthroplasties (16%: 4 of 25 cases) is higher than those of primary hip arthroplasties (2.6%: 5 of 214 cases). Among Nine dislocations, 8 cases (89%) were between fifth and seventh decade and all cases are men. All dislocations occured within 5 weeks postoperatively. Because 6 of 9 cases were due to poor compliance, the patient's cooperation during postoperative recovery is essential to prevent postoperative dislocation. The capsulectomy, surgical approach, or immobilization of patients after operation are unrelated to dislocaton. For the prosthetic factors, 7 cases dislocated posteriorly is appeared that the plane of the cup was between 3 and 9 degrees of anteversion, and also less than the normal range. Stable outcome without surgical operation was achieved in 7 of 9 dislocation. Among 2 patients who had recurrent dislocation after optimum conservative treatment, one had infected arthroplasty and the other had a impinged anterior thick capsule formation around the head. We concluded that the predisposing factors for dislocation after hip arthroplasty is multifactorial.

Journal of the Korean Ophthalmological Society 2014;55(8):1126-1131
PURPOSE: To describe the characteristics of patients with pinguecula between the ages of 20 and 39. METHODS: Thirty-two patients who visited our hospital between February 2013 and November 2013 for pinguecula were enrolled in the study. The clinical characteristics were evaluated by the location, size, shape, elevation, color, vascularization and the grade of pingueculae. RESULTS: Ninety-eight pingueculae were found in the 32 patients, 58 (59.18%) pingueculae on the nasal side, and 40 (40.82%) pingueculae on the temporal side. The mean grade of pingueculae of the nasal side was 1.19 +/- 0.40 and on the temporal side was 1.15 +/- 0.43. Compared with the temporal side, pingueculae on the nasal side were more frequent (p = 0.032). The size, color, shape and vascularization of nasal and temporal pingueculae were not significantly differentiated. Medical history, tear film break-up time, Schirmer test, history of contact lens wearing, refractive surgery, occupational activity and residence were not correlated with the grade of pingueculae. However, ocular surface disease index score was correlated with the grade of nasal pingueculae (p = 0.01). CONCLUSIONS: The pingueculae of the nasal side were more frequent than of the temporal side in patients between 20 and 39 years of age, and dry eye disease with tear film instability was also present. The ocular surface disease index score increased with the grade of nasal pingueculae.

Purpose:
To evaluate the clinical characteristics of Korean patients diagnosed with retinitis pigmentosa.
Methods:
We retrospectively reviewed the medical records of patients diagnosed with retinitis pigmentosa from January 2014 to December 2019. We evaluated age, gender, the chief complaints, posterior subcapsular cataract status, abnormalities on optical coherence tomography, visual field test results, and electrooculograms.
Results:
A total of 492 eyes of 246 patients were included. The mean patient age was 48.0 ± 16.0 years and the chief complaints were decreased vision and night blindness. The mean logarithm of the minimal angle of resolution (logMAR) best‐corrected visual acuity (BCVA) was 0.31 ± 0.50. The BCVA was 0.5 or better in 368 eyes (74.8%). A total of 328 (71.0%) of 462 eyes that underwent visual field testing exhibited visual field defects within 10º. The mean Arden ratio was 1.28 ± 0.28 for the 242 eyes that underwent electro‐oculography. Optical coherence tomography revealed vitreomacular traction/an epiretinal membrane, cystoid macular edema, and retinal thinning in 135 (27.4%), 48 (9.8%), and 112 (22.8%) eyes, respectively. The ellipsoid zone was intact in 222 eyes (45.1%), disrupted in 220 (44.7%), and absent in 50 (10.2%).
Conclusions
Most patients with retinitis pigmentosa exhibited visual acuity of 0.5 or better, but also had central visual field defects. Various abnormalities were noted on optical coherence tomography of most patients.

Diagnostic procedures in pregnant wowen is limited and is usually delayed, especially so if she is on mechanical ventilation. A 28-year-old pregnant woman with severe dyspnea was referred to our hopital under the impression of miliary tuberculosis. The respiratory failure was so severe that patient had to be managed with mechanical ventilator under clinical imression of overwhelming pneumonia or pulmonary tuberculosis. But the patient's conditions deteriorated. Bronchoscopy and blind transbronchial lung biopsy performed to determine the nature of the etiology, and to our surprise, revealed squamous cell carcinoma of the lung.

Hepatic artery pseudoaneurysm is a rare but potentially life-threatening condition that usually occurs after trauma. Early recognition and prompt management are essential for preventing catastrophic consequences, such as hemoperitoneum. We report a rare case of liver abscess caused byKlebsiella oxytoca resulting in hepatic artery pseudoaneurysm without iatrogenic injury. The unique feature of the present case is that the abscess cavity itself became a pseudoaneurysm as a result of fistula formation with the hepatic artery. Vascular complications should be considered in patients with unfavorable clinical course even in the absence of iatrogenic injury. Endovascular treatment is safe and effective.

Background:
A recent concern in breast reconstruction procedures is skin color mismatch of the pedicled transverse rectus abdominis myocutaneous (TRAM) flap. With the goal of objectively quantifying the skin tone of the TRAM flap donor site, contralateral breast, and flap, a comparative study was conducted.
Methods:
This study was conducted in July 2021, included 17 patients who received delayed breast reconstruction via TRAM flaps from January 2016 to December 2020 with at least 12 months of follow-up. Melanin levels and redness values of the flap, abdomen, and contralateral breast were measured in patients using a skin pigmentation analyzer. Furthermore, in 20 healthy women in their 40s to 60s, measurements were made of the abdomen, as well as breast.
Results:
The contralateral breast had lower mean melanin and redness than the abdomen. The flaps had slightly higher melanin levels than the contralateral breasts. The flaps tended to have higher redness values, but the difference was not significant. The difference between the flap and abdomen was significant for melanin, but not redness. Preoperative radiotherapy did not affect skin tone. The upper abdomen showed lower melanin and redness than the lower abdomen.
Conclusions
The breast had a brighter skin tone than the abdomen. The upper abdomen showed brighter skin tone than the lower abdomen, and the area used as the donor site of the TRAM flap presented the same tendency. In the process of TRAM flap engrafting, the melanin level of the tissue decreases, and the redness value tends to increase slightly compared to the contralateral breast.

Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is an uncommon type of malignant lymphoma that mainly occurs in the trunk and upper extremity, with less frequent incidence observed on the head. Herein, we report the early diagnosis and treatment of a rare case of facial PCMZL in an Asian patient. A 51-year-old man presented with masses on the forehead and nose tip, which he had incidentally discovered 2 months previously. The masses appeared as a papule on the forehead and a patch on the nose. There were no signs of infection or bleeding, and the patient reported no other symptoms. After complete surgical excision, PCMZL was diagnosed based on the permanent biopsy. The histopathological findings revealed lymphoid aggregations with multifocal granulomas. Further treatment and follow-up were conducted at the hematology and oncology department. Despite its rarity in Asian populations, cutaneous lymphoma should be included in the differential diagnosis of facial masses. Early diagnosis and treatment based on a physical examination, imaging study, and excisional biopsy are important for a favorable prognosis.
