Lymphomatoid papulosis(LyP) is a chronic recurrent dermatosi characterized by involuting and recurring papules, plaques, and nodules showing histologic feaurs suggesting rnalignant lymphoma. On histologic ground, it is divided into two types. type A and type B. In type A, large atypical lymphocytes are the main cellular cornponent and most of these express CD 30(Ki-1) antigen, which has been p!reviously thought to be specific for Read Sternberg cells of Hodgkins disease. In type B, cerebriform mononuclear lymphocytes sirr la to those in mycosis fungoides predominates. We report two cases of lymphomatoid papulosis, type A and type B, respectively. The large atypical cells in type A LyP expressed Ki 1 antigen. Both case were treated with PUVA and the outcome of the treatment has been fair.

BACKGROUND: Although actinic keratosis and Bowens disease ar considered as carcinoma in situ, most of them are biologically benign and dont progress to invasive squamous cell carcinoma. It is little known why they take the benign courses and which factors are involved in the tumorigenesis. Keratoacanthoma, self-regresi;ing benign tumor, may be sometimes or fused morphologically with well-differentiated squamous cell carcinoma. So it is necessary to find a useful marker to help us distinguish them. OBJECTIVES: We performed this study to gain a better understani ling of biologic behaviour and tumerigenesis of epidermal keiatinocytic neoplasms. METHODS: We investigated the expression of p53 protein and priliferating cell nuclear antigen (PCNA) by an immunohistochemical method on the formalin-fixed, araffinembedded tissue specimens of epidermal keratinocytic neoplasms. RESULTS: Fourteen out of 20 cases of squamous cell carcinoma(70.0%), 14 out of 22 cases of actinic keratosis(63.6%), and 13 out of 20 cases of Bowens disease(65.0%) showed p53 protein expression, but keratoacanthoma was negative. All the tumors studied sho ved significantly increased numbers of PCNA-positive eells when compared with normal epidermis and characteristic distribution pattern. of PCNA-positive cells. Most cases of actinic keratosis exhibited the basal dysplastic pattern, but Bo wenoid variants showed diffuse dysplastic pattern. Karatoacanthoma revealed the marginal pattern and Bowens disease showed the diffuse dysplastic pattern. Well-differentiated squamous cell carcinoria showed the basal dysplastic pattern, while poorly differentiated squamous cell carcinoma revealed d ffuse dysplastic pattern. CONCLUSION: Our results suggest that p53 mutation is a common and early genetic change in the epidermal tumorigenesis and may be used as a good marker for malignan transformation, but it does not seem to correlate with the biollagic behavior or prognosis of epidermal neoplasms. PCNA, which is considered as a proliferation-relaited marker, was expressed with chavaceristic distribution patterns according to the type of tumors, but the frequency of PCNA expression is unlikely to reflct the malignant potential of epidermal neoplasms.

PURPOSE: This study was aimed to explore and report the short term results of primary cementless hip arthroplasty in treatment of unstable intertrochanteric femur fracture in elderlys. MATERIALS AND METHODS: Between March 2009 and Feburary 2012, 35 arthroplasty cases performed by single surgeon and followed up for more than one year were evaluated. They were 21 females and 14 males with mean age of 78 years (range, 71-92 years). Preoperative evaluation was performed by American Society of Anesthesia score. Retrospective evaluation was performed by operative time, transfusion amount, time to operation days, hospital stay and time to full weight bearing. Clinically, ambulatory ability was checked by Parker and Palmer (P&P) score and function of hip was appraised by Harris hip score (HSS). Radiologically, bone healing of fractured trochanteric fragment and presence of subsidence, stress shielding or osteolysis were checked. RESULTS: Fracture type was 11 cases of A2.2, 18 cases of A2.3 and 6 cases of A3.3. Femoral stems used were 8 cases of rectangular tapered wedge type and 27 cases of fluted modular distal fixation type. P&P score improved from mean preinjury score of 7.1 to mean postoperative last follow-up score of 6.5. Median HHS at last follow-up was 75. Mean time to full weight bearing was 47 days (24-79 days). Postoperative complications were one case of linear periprosthetic femoral fracture and one case of postoperative dislocation. CONCLUSION: Cementless hip replacement arthroplasty could be a good option for unstable intertrochanteric femoral fracture in elderlys.

We have had an opportunity to study a patient with acute sensory neuronopathy. The patient was a 32-yearold housewife; the rapidly spreaded tingling sensation along both arms and legs developed, rendering her severely ataxic. There was no history of antecedent illness, familial neurological disease, or exposure to toxins and special drugs. On examinations, there was no abnormality in her mental and cranial nerve function. There was no motor weakness. She showed the profound loss of kinesthetic sense which was acutely progressive and associated with severe sensory ataxia and pseudoathetosis. All tendon reflexes were absent. However, cutaneous senses were preserved. There was no significant abnormal laboratory finding except elevated CSF protein content. On electrophysiologic findings, the decrease in the amplitude of action potentials with only mild slowing of conduction velocities of sensory nerves were found even though motor nerve conduction studies were normal. Median and tibial somatosensory evoked potentials could be elicited, although the median N19 scalp response and tibial N45 waveforms were prolonged in latency. Plasmapheresis were provided; clinical features improved. However, the electrophy-siological abnormalites remained. Thus we wish to report an additional case of woman suffering from the acute sensory neuronopathy, complementing the cases described by Stemm, Schaumburg and Asbury.

BACKGROUND: A novel technique for the repair of tears of the upper subscapularis tendon—intraarticular knotless fixation—has been introduced recently. The purpose of this study was to evaluate the clinical and structural outcomes of arthroscopic intraarticular knotless fixation for the treatment of upper subscapularis tendon tears. METHODS: We retrospectively analyzed the clinical and radiological outcomes of 27 patients who underwent arthroscopic intraarticular knotless fixation for upper subscapularis tendon tears. Finally, a total of 10 patients who could participate in at least a 6 month follow-up of magnetic resonance imaging evaluation and in a least 1-year follow-up on an outpatient basis were enrolled in our study. The mean age at the time of operation was 60.7 years, and the mean duration of follow-up was 14.7 months. Two patients had concomitant tears of the supraspinatus tendon and 8 patients had concomitant tears of the supraspinatus and the infraspinatus tendons. RESULTS: The clinical and radiological outcomes improved after the patients had undertaken arthroscopic intraarticular knotless fixation. The mean visual analogue scale score for pain during motion improved from 6.7 preoperatively to 1.4 at the final follow-up (p<0.001). The mean Constant score improved from 59.3 preoperatively to 79.6 at the final follow-up, and the mean the University of California at Los Angeles score, from 21.7 to 30.2, respectively (p<0.001 and p<0.001). The upper subscapularis tendon tear was healed in every patient except one (90%), for the patient had suffered from a postoperative trauma that resulted in a retear. CONCLUSIONS: We found that arthroscopic intraarticular knotless fixation gives good clinical and structural outcomes for the repair of upper subscapularis tendon tears. Arthroscopic intraarticular knotless fixation provided such a reliable and efficient restoration of the subscapularis tendon footprint that we anticipate it will become a widely-used procedure for upper subscapularis tendon tears.

9.Open Surgical Treatment for Femoroacetabular Impingement in Patients over Thirty Years: Two Years Follow-up Results.
Hip & Pelvis 2015;27(4):241-249
PURPOSE: We report short term results of open surgical treatment for symptomatic femoroacetabular impingement (FAI) in patients over the age of 30 years. MATERIALS AND METHODS: Between May 2011 and June 2012, thirteen FAI hips (11 patients) with hip pain persisting longer than 6 months were treated by either surgical hip dislocation (SHD) or anterior mini-open. They were followed up for longer than 2 years. The 11 patients included 7 females and 4 males with a mean age of 45 (range, 33-60) years. They were clinically evaluated for modified Harris hip score (MHHS) and University of California at Los Angeles (UCLA) activity level. Their lateral center-edge angle, acetabular index, and alpha angle were measured and compared. RESULTS: Acetabuloplasties were performed for seven cases. Femoral osteochondroplasty was performed for all thirteen cases. At minimum follow-up of two year (range, 24-29 months), all patients had substantial relief in preoperative pain with improvement in range of motion. The median MHHS was significantly (P<0.05) improved from 61 points preoperatively to 87 points at the last follow-up. The median UCLA activity level was 7 (range, 5-8) at last follow-up. Radiological indices improved. Two cases showed mild residual pain attributable to adhesion between capsule and reshaped femoral head-neck area. CONCLUSION: Open surgical treatment of FAI was a reliable and effective treatment method in symptomatic FAIs for patients over the age of 30 years without advanced arthritic change of hip joint at short term follow-up.
