Discoid semilunar cartilage is an abnormality in which the meniscus is discoid rather than semilunar, and first reported by Young of Glasgow in 1889. 13 cases of discoid semilunar cartilages which were experienced at the Department of Orthopedic Surgery, College of medicine, Seoul National University from Jan. 1956 till Aug. 1972 are reported with review of literature. 1) The incidence was remarkable higher in the male than in the female as 11 versus 2, and higher in the age group of second decade (Average 16.4 year old). 2) Most common site was lateral meniscus, and bilateral discoid meniscus were 3 cases. 3) 3 cases out of 13 cases had complicated rupture of semilunar cartilage, and one case had cyst of the meniscus. 4) Meniscectomy were performed in all cases with successful outcome.

Fractures of the tibial condyles, involving as they do weight-bearing articular surfaces and important soft tissues such as collateral ligaments, cruciate ligaments and semilunar cartilages present a variety of problems in treatment and prognosis. Apley, Slee, and others maintained the opinion that most fractures of the tibial condyles could be managed conservatively. On the other hand, Rombold, Schatzker, and others seemed to consider closed treatment to be virtually a form of therapeutic nihilism and adviced open reduction. But recently most authors agree that the method of treatment has to be selected in each individual case, and recommend anatomical reduction of the fracture as possible and early knee motion. During 7 years period from January 1974 to July 1981, of the tibial condylar fractures treated at the department of orthopaedic surgery, Han Gang Shim Hospital, 41 cases that could be followed have been analysed according to the cause, classification, method of treatment and result. The following results were obtained from the analysis of 41 tibial condylar fractures. l. Of the 41 cases, 34 (83%) were male and 7 (17%) were female. 2. Of the 41 cases, 32 (78%) were due to traffic accident, 25 pedestrian, 7 occupant, 8 (20%) were due to fall from height. 3. Of the 41 cases, 31 (76%) were associated with other injuries. 4. Of the 41 cases, 30 were treated by conservative method with functionally acceptable result in 22 cases (73%) and 11 were treated by open reduction with functionally acceptable result in 9 cases (82%). 5. According to the Hohl and Luck's criteria, acceptable functional result was obtained in 31 (76%) cases.

Purpose: Pathologic lesions may occur in an axillary accessory breast (AAB). This study aimed to evaluate the characteristics of tumors arising from AABs and to recommend appropriate treatment. Methods: This retrospective study involved 3,544 women (18–65 years old) with AAB at Damsoyu Hospital in Korea from 2014 to 2023. The patients were divided into an AAB with benign tumors (TAAB) group and an AAB without tumors (AAB) group, and the tumors’ pathologies were reviewed. A core biopsy was performed on tumors with possible malignancy identified by preoperative ultrasonography. All patients underwent complete excision of accessory mammary gland (AMG) tissue, including tumors. The postoperative results were checked 6 months after surgery. Results: Fifty-two out of 3,554 patients had tumors confirmed by preoperative ultrasonography. Preoperative core biopsies were performed on 11 patients. Two patients had malignant tumors (invasive ductal carcinoma) identified by core biopsy.Fifty patients had benign tumors identified by postoperative pathological analysis (46 fibroadenomas, 2 fibrocystic changes, and 2 sclerosing adenoses). Carcinoma in situ was confirmed in 2 patients using postoperative pathological analysis. No patients in either group developed tumors in the axilla during the follow-up period. All patients were satisfied with the axillary pain relief and the disappearance of bulging lesions. Conclusion We recommend a core biopsy if preoperative ultrasonography indicates a possibly malignant tumor. AAB patients may experience tumors, pain, and bulging appearance of an AMG; thus, complete AMG excision is necessary.

The effect of pinacidil, a K+ channel opener, on the contraction of rabbit carotid artery was investigated by using muscle contraction and Ca2= uptake experiments. Pinacidil reduced phenylephrine-induced contraction by dose dependent manner, which was antagonized by glibenclamide, a blocker of the ATP sensitive K+ channel. Phenylephrine-induced tonic contraction was more reduced by pinacidil than its phasic contraction. In the effect of pinacidil on the Ca2+ uptake of rabbit carotid artery, pinacidil decreased it at the resting state of tissue, dose-dependently. Phenylephrine-induced stimulation of Ca2+ uptake was also reduced by pinacidil. Pinacidil 10micrometer reduced high potassium-induced contraction, which was not reversed by glybenclamide 10micrometer. Threshold concentration of K+ increased by pinacidil pretreatment. Phorbol 12, 13-dibutyrate, an activator of protein kinase C, induced sustained contraction of rabbit carotid artery, which was reduced by pinacidil but not antagonized by glibenclamide. In Ca2+-free buffer, pinacidil also decreased phorbol 12, 13-dibutyrate-induced contraction. These results indicate that pinacidil reduces Ca2+ uptake of vascular smooth muscle by stimulation of K+ channel which could be antagonized by glibenclamide, and another mechanism of vasorelaxation which could not be antagonized by glibenclamide. It was indecated that pinacidil affects the contaction of smooth muscle by the inhibition of protein kinase C.

It is well known that Bowen's.disease, a precancerous dermatosis can be associated with internal malignancy. We report 2 cases of Bowen's disease of probable arsenic origin associated with. internal malignancies. Case one, a 55 year-old man, who had the past history of arsenic intake and herb medication for the treatment of suspicious leprosy, had Bowen's disease and arsenical keratosis on his palms and soles with bronchogenic and stomach carcinoma. The other case, a 65 year-old man, who had history of intake of arsenic and herb medicine for epilepsy, had Bowen's disease and squamous cell carcinoma of the skin with stomach cancer. We suggest that in these 2 cases, the ingestion of organic arsenics might be the causative factor for the internal malignancy.
