BACKGROUND: To investigate the effectiveness of reverse total shoulder arthroplasty (RTSA) in treating irreparable massive rotator cuff tears (RCTs). METHODS: Twenty-nine patients who underwent RTSA for the treatment of irreparable massive RCTs and completed follow-up for at least 1 year were selected. Their mean age was 69.7 years (range, 59-80 years). The mean follow-up was 17.7 months (range, 12-42 months). The shoulder range of motion was measured preoperatively and at final follow-up. The functional result was evaluated using visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeon (ASES) score, and Korean Shoulder Society (KSS) score. Additionally, the shoulders were categorized into two groups depending on prior history of surgery and the clinical outcomes were analyzed between two groups. RESULTS: Mean pain VAS improved, from 6.6+/-1.2 to 2.7+/-0.9 (p=0.001), and the mean functional VAS from 35.7+/-4.2 to 73.3+/-5.4 (p=0.006). The mean ASES score improved from 37.2+/-2.8 to 75.0+/-3.8 (p=0.012). The mean KSS improved from 36.5+/-7.2 to 75.6+/-5.4 (p=0.009), the mean forward elevation from 66.3+/-4.7 to 135.6+/-8.4 (p=0.0001), and the mean abduction from 45.2+/-4.2 to 119.0+/-6.5o (p=0.0001). Internal rotation differed significantly from the first sacral to the third lumbar vertebrae (p=0.036). External rotation did not change significantly (p=0.076). There was also no statistically significant difference between groups (no previous operation versus none). Four complications occurred: one superficial infection, one with anterior dislocation, one acromial fracture, and one clavicle fracture. CONCLUSIONS: RTSA provides reliable pain relief and recovery of shoulder function in patients with massive irreparable RCTs in short-term follow-up.

PURPOSE: The purpose of this study is to assess the effect of Transcatheter Arterial Embolization(TAE) according to anglographic findings in hepatocellular carcinoma. MATERIALS AND METHOD: We retrospectively reviewed 50 cases who received TAE for unresectable hepatocellular carcinoma. We analyzed the anglographic findings which were correlated with the effect of TAE. The common anglographic findings of the hepatocellular carcinoma were tumor staining, neovascularity and enlargement of feeding artery. These anglographic findings were classified into grade 0, +1, +2. Effect of TAE were classified into five patterns;good response, partial response, minimal response, no response and more aggravation. RESULT:In grading of tumor staining, among 50 cases, the grade 0, +1, +2 were seen in 1 case(2%), 14 cases(28%), 35 cases(70%) each. In grading of enlargement of feeding artery, the grade 0, +1, +2 were seen in 7 cases(14%), 19 cases(38%), 24 cases(48%) each. In grading of neovascularity, the grade 0, +1, +2 were seen in 6 cases(12%), 15 cases(30%), 29 cases(58%) each. This study showed that the higher grade of anglographic finding, the better effect of TAE. A statistically significant differance was found (p<0.005). But the TAE was not effective in some cases (the maximum diameter of mass is over 10cm, portal vein thrombosis or ateriovenous shunt) in spite of high grade. CONCLUSION: We believe that these angiogr. aphic findings (tumor staining, enlargement of feeding artery, neovascularity) are one of important indices for anticipating the effect of TAE in patients with unresectable hepatocellular carcinoma.

We herein present a rare case of a 42-year-old man with primary cutaneous marginal zone lymphoma(MZL) of the B-cell type on his shin. MZL is known to be the cutaneous counterpart of MALT(mucosa-associated lymphatic tissue) lymphoma. Histopathologically, MZL is characterized by multi-nodular infiltrates of centrocyte-like and centroblast-like marginal cells with bottom-heavy patterns, lymphoplasmacytoid differentiation, typical distribution of tumor cells in the marginal zone and follicular colonization by tumor cells. This B-cell lymphoma of a benign grade should be differentiated from mantle cell lymphoma and follicular center cell lymphoma.

We herein report a case of Richters syndrome(RS) that was discovered following an investigation of a skin lesion. RS represents an acute transformation of chronic lymphocytic leukemia(CLL) to highly malignant large cell lymphoma such as diffuse large B-cell lymphoma(DLBCL). RS is characterixed by abrupt B-symptoms, rapidly progressive lymphadenopathy, hepatosplenomegaly, frequent extranodal involvement, hypercalcemia and an unfavorable clinical course. The patient is a 31-year-old male with skin lesions on his face. He had been previously diagnosed with CLL. At his presentation, CLL and DLBCL manifestly co-existed. Our multistage analysis suggested that DLBCL and CLL might arise from a different B-cell clone. He showed a poor clinical response to systemic chemotherapy.

BACKGROUND: Traditionally, herpes zoster (HZ) has been known to be a recrudescence of a latent viral infection of sensory ganglia, with the spread of the virus along sensory nerves and a dermatomal cutaneous eruption. However, clinically detectable muscular wenkness often occurs in patients with HZ. Accordingly, segmental or non-segmental motor neuron involvement by HZ may occur in addition to the involvement of sensory ganglion. OBJECTIVE: This study was conducted to estimate the frequency of motor neuron involvement in patients with HZ in Korea. METHODS: Fifty six subjects with HZ were enrolled in this study which used a conventional needle EMG (electromyography) and motor nerve conduction velocity test. Studies were conducted a minimum of 2 weeks after the onset of the rash. EMG was performed on the ipsilateral paravertebral muscles at the dermatomial levels of the eruption and controlateral sides. RESULTS: 1. One or more abnormal EMG findings(fibrillation potential, positive waves, bursts of high frequency discharge, polyphasia, fasciculation) were found in 51.8% of HZ patients. 2. Among the subjects with motor involvement, thoracic dermatome was most frequently involved (58.6%). 3. Ipsilateral motor involvement was more common(72.5%) than controlateral involvement(27.5%) among the patients with abnormal EMG findings. 55.2% of patients showed non-segmental motor involvement and that the altered EMG findings were not confined to the segment invaded by the eruption. 4, There was no association between the presence of postherpetic neuralgia or severity of pain or initial allodynia and EMG changes. CONCLUSION: Segmental or non-segmental motor neuron involvement by HZ may not be uncommon in Korea. HZ seems to cause widespread motor nerve changes, albeit usually subclinical alterations in the motor system, easily identifiable on EMG.

Herein we report two cases of leukemia cutis that were responsive to oral all-tratm retinoic acid(ATRA) therapy. The two presented patients, who had been diagnosed with acute pmmyelocytic leukemia, disclosed specific lesions of leukemia cutis through histopathological examinations. Leukemia cutis due to acute promyelocytic leukemia is characterized by PML/RAR-a chimeric fusion proteins which arise from chromosomal trmslocation. This PML/RAR-a transcript can be a valuable molecular therapeutic target to systemic retinoid therapy in that ATRA induces terminal differentiation of leukemic clones and PML/RAR-a transcript preserves the ATRA-responsive signal transduction pathway. We concluded that leukemia cutis might be treated by tretinoin therapy without notifi.able adverse effects.

Eccrine nevus is an unusual entity with various clinical manifestations. Histologically the eccrine apparatus appears simply increased in number and/or size, but structurally normal. We present a case of eccrine nevus on the dorsum of the left 3rd and 4th fingers in a 20 year-old female. The lesions were 3 × 2cm sized, well demarcated, smooth surfaced, brownish plaques with mild hyperhidrosis. Histological examination revealed hyperkeratosis in the stratum corneum and hyperpigmentation of basal layer, and an increased number of eccrine sweat glands and many eccrine coils in the dermis was seen.

Amid the coronavirus disease 2019 era, concern about the safety of surgical teams related to surgical smoke (SS) is rising. As simple ventilation improvement methods (SVIMs), we replaced 4 of the 8 supply diffusers with a direction-adjustable louver-type, closed 2 of the 4 exhaust grills, and strengthened the sealing of the doorway. Dynamic changes in the concentration of particulate matter (PM) with sizes of < 1.0 μm (PM1.0) were measured using low-cost PM meters (LCPMs) at eight locations in the operating room (OR). SS concentration up to 4 minutes at the location of the surgeon, first assistant, and scrub nurse before and after SVIMs application decreased from 65.4, 38.2, 35.7 µg/m 3 to 9.5, 0.1 and 0.7 µg/m 3 respectively. A similar decrease was observed in the other 5 locations. SVIMs could effectively control SS and the LCPM was also effective in measuring SS in the OR or other spaces of the hospital.
