Lymphomatoid papulosis is an enigmatic disease entity which is clinically benign and histologically malignant. Although sporadic cases have been reported, we could not find any comprehensive report on the combined clinical and histologic features of lymphomatoid papulosis in the literature. Perhaps the most controversial aspect of lymphomatoid papulosis is its pathogenesis and categorization as a benign versus a malignant entity. To date, there are no reports on p53 and bcl-2 protein expression in lymphomatoid papulosis. We analysed the clinico-pathological findings of 18 cases with lymphomatoid papulosis during the 10 year period from 1984 to 1995 and examined the prevalence of immunoreactivity for CD30(DAKO, Ber-H2), p53(DAKO, DO-7), and bcl-2(DAKO, 124) using an immunohistochemical(ABC) method. The results obtained are summarized as follows. 1) Age distribution ranged from 20 to 65, with a mean age of 45 years and a sex distribution which showed a male predominence(8:1). The lesions were located on the trunk and extremities(8cases), extremities (7cases), and trunk(3 cases). The morphology of the lesions were papules or plaques(12 cases), and nodules(6 cases). 2) Histopathologic types were classified into 3 types: type A(4 cases), type B(8 cases) and mixed type (6 cases). 3) Positive immunoreactivity for CD30 was seen in 17%(3 of 18cases): type A(2 of 3) and mixed type(1 of 3). 4) The positive immunoreactivity for p53 and bcl-2 was observed in 29%(5 of 18) and 11%(2 of 18), respectively. 5) Cases showing positive immunoreactivity for P53 were type A(1 of 5), type B(1 of 5), and mixed type(3 of 5). 6) Cases showing positive immunoreactivity for bcl-2 were mixed type(2 of 2). One case developed into Ki-1 lymphoma. These results support the idea that lymphomatoid papulosis and Ki-1 lymphoma represent a continuum. The role of p53 gene mutation and bcl-2 activation in the development of lymphomatoid papulosis is currently unknown. But, our results suggest that p53 gene mutation and bcl-2 activation are not a critical step in the development of lymphomatoid papulosis. Further studies are needed to elucidate the role of p53 gene mutation and bcl-2 activation in the development and progression of lymphomatoid papulosis.

Alterations in the expression of genes that control the cell cycle may be of critical importance in tumorigenesis and malignant transformation. The major regulatory events leading to cell proliferation occur in Gl phase of cell cycle, and the deregulated expression of Gl cyclins is related to oncogenesis. Cyclins Dl and E play important roles in the progression of cell through Gl phase of the cell cycle. Amplification and/or overexpression of the cyclin Dl gene and aberrant expression of cyclin E has been described in various forms of human cancer. However, the role of cyclins Dl and E in cervical cancer has been poorly defined. In this study, we examined the expression of cyclins Dl and E by Northern blot technique and the status of human papil- lomavirus(HPV) type 16 and 18 by polymerase chain reaction in 25 cases of cervical carcinoma to explore the relationship between cyclins Dl and E and cervical cancer. We found cyclin Dl expression showed down-regulated expression in cervical cancer but cyclin E expression was increased in cancer group. Other clinicopathological prognostic factors were not correlated with cyclins D1 and E expression. Further study based on larger numbers of cases with correlation of cyclins D1 and E status and survival data will be needed to elucidate the use of cyclin expressions as prognostic factor.

Cell Adhesion Molecule(CAM) is a cell surface glycoprotein that plays an important role in many inflammatory reaction. This is responsible for the migration and accumulation of different populations of leukocyte in inflamed tissues. To investigate the relevance of CAM expression to giant papillary conjunctivitis associated with type I and/or type IV hypersensitivity, the histology of conjunctival giant papillae from patients with papillary conjunctivitis was examined with light microscopy and using indirect immunofluorescent staining method with monoclonal antibodies against the ICAM-1, VCAM-1, and CD44. The infiltrates of the inflammatory cells such as eosinophil, basophil, plasma cell and lymphocyte were noted in conjunctival stroma by light microscopy. The ICAM-1, VCAM-1, and CD44 were expressed or upregulated in stroma and vascular wall by immunofluorescent method. These findings suggest that CAM may play a key role in the pathogenesis of giant papillary conjunctivitis. Further efforts to block or modulate the expression of CAMs may provide new therapeutic modalities in the treatment of conjunctival disease.

BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

Our objective is to describe the CT features of exophytic hepatic tumors those may pose a diagnostic challenge because of the uncertainty of tumor origin. The beak sign and the feeding artery of a tumor are useful diagnostic indicators of exophytic hepatic tumors. Two- or three-dimensional reformation images are also helpful for diagnosis. The CT features of exophytic hepatic tumors are similar to those of the usual intrahepatic tumors except for their location.

We present an interesting case of incidental diffuse fluorodeoxyglucose (FDG) uptake at PET in her left breast, related to atypical breastfeeding practice. Clinically, differential diagnoses of diffuse intense FDG uptake in unilateral breast include advanced breast cancer, breast lymphoma and inflammatory condition. However, normal physiologic lactation may also show increased FDG uptake in the breasts. Therefore, if we encounter that finding in daily practice, we should question the patient regarding unilateral breastfeeding. In addition, mammography and ultrasound would be helpful to confirm the diagnosis.

PURPOSE: To investigate the relationship between maturity of a cataract and the pattern of pain during cataract surgery under topical anesthesia. METHODS: This study comprised 105 eyes of 75 patients undergoing cataract surgery under topical anesthesia. The pain scale during each procedure was scored from 0 to 10 in numeric pattern and analyzed with the cataract maturation degree. Additionally, pain scores were compared between the first and the second eye in 14 consecutive cataract patients. RESULTS: The average pain score during cataract surgery was 0.86 +/- 0.55, and the average maximal pain experience score during surgery was 3.24 +/- 1.51, which was generally tolerable. Phacoemulsification was marked as the most painful step among cataract surgery procedures (1.93 +/- 1.64), followed by the removal of the surgical draping (1.31 +/- 1.53) and the initial instillation of topical anesthetic (1.29 +/- 1.28). Progression and cataract typing was not related to pain either during overall cataract surgery procedures or when separately analyzed during procedures. There was no significant difference between the pain scores reported in consecutive cataract surgeries. However, in subjective comparison of consecutive surgeries, more patients reported greater pain in the second operation. CONCLUSIONS: The pain score reported during cataract surgery procedures under topical anesthesia was within a generally tolerable range. Cataract progression does not appear to be related to pain during the operation. In consecutive surgeries, pain measured by a numerical scale and subjective pain experience showed different results.

PURPOSE: To evaluate the proper volume measurement of prostate with focal intravesical protrusion of enlarged central gland by comparison between methods using craniocaudal length from top of protruded central gland and from prostate base near bladder neck to prostate apex. MATERIALS AND METHODS: We made 20 prostate models with focal intravesical protrusion (volume range: 20~50 mL, height of protrusion: about 1 cm) using devil's tongue jelly. Two radiologists measured volume of models 3 times by two kinds of methods using craniocaudal length from top of protruded central gland (method 1) and from prostate base near bladder neck (method 2) by transrectal ultrasound. The accuracy of volume measurement of models was evaluated statistically by comparing their average volume to true volume. Intra- and interobserver agreement was also evaluated. RESULTS: Average true volume of models was 31.05 mL. Each average volume using method 1 by two observers was 37.07 mL and 38.56 mL. Each average volume using method 2 was 30.69 mL and 31.55 mL. Volume measurement using method 2 was approximated to true volume of prostate statistically (p = .654, .823). There was no significant inter- and intra-observer variation in both methods. CONCLUSION: To measure the accurate volume of porstate with focal intravesical protrusion of enlarged central gland, its craniocaudal length should be measured from prostate base near bladder neck.

Background:
The impact of persistent coronavirus disease 2019 (COVID-19) symptoms on quality of life remains unclear. This study aimed to describe such persistent symptoms and their relationships with quality of life, including clinical frailty and subjective health status.
Methods:
A prospective longitudinal 3-month follow-up survey monitored symptoms, health quality, support needs, frailty, and employment.
Results:
A total of 82 patients with a mean age of 52 years (ranging from 23–84 years) were enrolled, including 48 (58.6%) men, and 34 (41.5%) women. The fully active status decreased from 87.8% before admission to 78.1% post discharge. Two patients (2.4%) were ambulatory and capable of all self-care but unable to carry out any work-related activities 12 weeks after discharge. Clinical frailty scale (CFS) levels 1, 2, 3 and 4 changed drastically between admission and 12 weeks later after discharge. Just after admission, the median EuroQol visual analogue scales (EQ-VAS) was 82.23 (± 14.38), and it decreased to 78.10 (± 16.02) 12 weeks after discharge; 62 (75.6%) of patients reported at least one symptom 12 weeks after discharge. The most frequent symptom was fatigue followed by smell disorder, anxiety, sleep disorder, headache, depressive mood, dyspnea, and taste disorder. CFS was definitively associated with fatigue. Decreased EQ-VAS was associated with fatigue and palpitation, cough, taste disorder, and chest pain. EQ-VAS was worse in women (28%) than in men. Compared with regular outpatient clinic visits before admission, 21 patients (25.6%) reported increased outpatient clinic visits, one (1.4%) reported readmission, and one (1.4%) reported emergency room visits. Six of the 54 (77.1%) patients who were employed before admission lost their jobs. And most vulnerable type was self-employed, because three selfemployed job workers were not working at 12 weeks after discharge.
Conclusion
COVID-19 sequelae should not be underestimated. We find a decrease in health quality and increase in psychological problems in discharged COVID-19 patients, and some patients experience unemployment. The number of patients suffering from COVID-19 sequelae would not be negligible considering there are more than one million COVID-19 infection cases in Korea. Hence, the government should start a systematic monitoring system for discharged patients and prepare timely medical and social interventions accordingly.
