Spontaneous testicular hemorrhagic necrosis is a rare disease usually associated with testicular torsion. Partially involved and suspicious testis tumor cases are also defined from orchiectomy specimens. Herein, a spontaneous hemorrhagic necrosis, without any testicular torsion, but with involvement of the whole testicle and epididymis, is reported. A 21 year old patient, who presented with a painless left testicular enlargement of several days duration was believed, based on physical examination, ultrasonography and elevation of serum LDH, to have a testicular tumor. Diagnosis was made only after radical orchiectomy and histopathological examination.

Background:
Irreparable anterosuperior rotator cuff tears (IASRCTs) present significant challenges, especially in young, active patients with limited joint-preserving options. Recently, latissimus dorsi (LD) transfer and combined latissimus dorsi and teres major (LDTM) transfer have gained attention as a potential surgical option. We aimed to compare the clinical and radiological outcomes of LD versus combined LDTM transfer in IASRCTs.
Methods:
In this retrospective comparative study, 53 patients with IASRCTs were analyzed after undergoing either LD transfer attached to lesser tuberosity (LT) (LD group, n = 23) or combined LDTM transfer attached to greater tuberosity (GT) (LDTM group, n = 30). Clinical evaluations included the visual analog scale score for pain, active shoulder range of motion (ROM), University of California Los Angeles Shoulder Score, American Shoulder and Elbow Surgeons score, activities of daily living that require active internal rotation (ADLIR) scores, and subscapularis (SSC)-specific examinations. Radiographic analyses involved assessing acromiohumeral distance (AHD), Hamada grade, the rate of anterior glenohumeral subluxation reduction, and integrity of the transferred tendon.
Results:
Postoperatively, both groups demonstrated significant improvements in pain and clinical scores (p < 0.001). At the 2-year follow-up, the LDTM group showed superior internal rotation strength (p < 0.001), ADLIR score (p = 0.017), and SSC-specific physical examination results (belly-press, p = 0.027; bear-hug, p = 0.031; lift-off, p = 0.032). No significant changes in AHD or Hamada grade were observed in either group. At final follow-up, no significant differences were found between the 2 groups in terms of AHD (p = 0.539) and Hamada grade (p = 0.974). Although preoperative anterior glenohumeral subluxation was improved in both groups, the LDTM group showed a statistically significantly higher rate of restoration compared to the LD group (p = 0.015).
Conclusions
While both LD and combined LDTM transfers for IASRCTs improved postoperative pain relief, clinical scores, and active ROM, the combined LDTM transfer attached to GT was superior to LD transfer attached to LT in terms of internal rotational strength, ADLIR score, and SSC-specific examinations. Neither group showed significant progress in cuff tear arthropathy or decreased AHD at 2-year follow-up; however, the combined LDTM transfer notably improved preoperative anterior glenohumeral subluxation.

Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

BACKGROUND: Brief episode of coronary artery occlusion (i.e., ischemic preconditioning) makes the heart more resistant to injury from a subsequent ischemic insult. Although a great deal of effort has been made in studying ischemic preconditioning, the underlying mechanism of ischemic preconditioning and its effect on hypothermic insult has not been elucidated. This study was performed to see whether ischemic preconditioning protects against the depression of cardiac contractility induced by hypothermic cardioplegic arrest/reperfusion. And recently, adenosine was known to have some correlation with the mechanism of preconditioning. If so, does this effect remain after the blockade of adenosine receptor by 8-phenyl theophylline? METHOD: Twenty-four Sprague-Dawley rat weighed 250-350g were used and divided into three groups. Rat hearts were removed rapidly, and each isolated heart paced with a rate of 180/min was perused by modified Krebs-Hensleit buffer(KHB) solution on a Langendorff apparatus far an hour. After obtaining baseline data including left ventricular pressure(LVP), dp/dt, and coronary flow, cardiac arrest was induced by perfusion of 0degrees C crystalloid cardioplegic(St Thomas) solution. After that, all hearts were stored in the same St Thomas solution at salute temperature far 2 hours. In group I (control group), the hear was reperfused by KHB solution. In group II(preconditioning group), the heart was subjected to two 2-minute episode of global ischemia followed by 5 minute reperfusion with KHB solution(preconditioning) before cardiac arrest. In group III(phenyl theophylline group), the heart was subjected to preconditioning procedure and 8-phenyl theophylline at 10muM in concentration was added to KHB solution at time of reperfusion. Observing parameter was obtained in each group at 10, 20, 40 and 60 minutes after starting reperfusion and compared statistically by use of one way ANOVA test(STASTICA, release 4.5). P-value less than 0.05 was considered significant. RESULTS: Although depressed LVP, dp/dt, and Coronary flow were seen in all groups during the reperfusion period, the preconditioned group showed more effective recovery of LVP than that of the control group, especially at 10, 20 and 40 minutes(p<.05). We failed to demonstrate the difference between the phenyl theophylline group and the control group(p=NS). CONCLUSION: These results suggest that ischemic preconditioning has protective effect on recovery state of hypothermic cardioplegic arrest/reperfusion. Its protective effect was limited during early reperfusion stage and was blocked by adenosine blocker.

8.2 Cases of Limbal Autograft Transplantation after Chemical/Thermal Corneal Burns.
Journal of the Korean Ophthalmological Society 1995;36(2):199-204
A severe chemical or thermal injury is a troublesome ocular insult, which usually results in persistant corneal epithelial defect, stromal scarring, and neovascularization. For resurfacing chemically burned cornea, limbal autograft transplantation is presented in 2 cases of chemical and/or thermal injury with follow-up of 6, 8 months. The operative technique involved transfer of four free grafts of limbal tissue from the uninjured fellow eye to the severely injured eye. Clinical results of the cases have shown surface healing with stable epithelial adhesion without recurrent erosion or persistant epithelial defect.

Magnetic resonance imaging(MRI) is accepted as a useful tool for the diagnosis of injury of the knee recently. The anterior cruciate ligament tear is accompanied by the damage of the osseous and soft tissue of the knee. The occult osseous lesion is found on magnetic resonance imaging as bone density change that is not found on the simple radiograph. From Jan. 1992 to Apr. 1994, magnetic resonance imaging was performed on 44 patients with acute anterior cruciate ligament tears. MRI was done within 6 weeks of the index anterior cruciate ligament injury. The criteria of decreased signal intensity on the Tl weighted image and increased signal intensity on the T2 weighted image was applied for the incidence assessment of the occult osseous lesion. After arthroscopy with or without ACL reconstruction, follow-up simple radiograph was checked every 3 months. Occult osseous lesions were documented in 32(73%) of the 44 patients. Of the 32 patients with bony lesion, 81% had lesions of the lateral compartment. Lateral femoral condyle was involved in 15 cases(46.9%), and lateral tibial plateau in 22 cases (68.8%). Follow-up X-ray revealed no joint deperession in all of the 32 patients with the occult osseous lesion. This result suggests that there is a high correlation between the occult osseous lesion of lateral compartment of the knee on magnetic resonance imaging and anterior cruciate ligament tear. The presence of the occult osseous lesion in the patient with acute anterior cruciate ligament tear did not affect rehabilitation and weight bearing.
