1.Splenic Lymphangioma: A case report.
Korean Journal of Pathology 1994;28(5):533-535
Lymphangioma of the spleen is a rare neoplasm and approximately 100 cases have been reported in the world literature. This lesion may involve the spleen alone or may be a part of a syndrome of multivisceral involvement. The pathogenesis is unclear whether this is a true neoplasm of a developmental defect. We report a case of a 87-year-old woman with solitary splenic lymphangioma. The cut surface mass is not encapsulated and located at the subcapsular area in the mid portion of spleen. It is composed of variable sized cystic spaces containing myxoid tissue. Microscopic finding reveals dilated lymphatic spaces lined by endothelial cells and the content is proteinaceous eosinophilic fluid.

This paper describes the incidence of transport accident for the period, 1955-1965. Transport accidents were classified into three categories, viz. railway(WHO Classification of Diseases, E-802), watercraft(E850-E858) and motor vehicle accidents(E810-E835, E840-E841, E844-E845). Crude data on the subject were collected from the various sources of Government Statistical Books including Statistical Year Books edited by the Central Office of Economic Planning Board, Annual Police Reports by the Ministry of Home Affairs, and the national and local associations for road traffic safety. From the data incidence and mortality rates by year, month and local province were computed and other variables relevant to the epidemiology of accidents were observed. The following summary could be drawn: 1. Death rates due to transport accidents per 100,000 population were 12.3 for 1955 and 9.7 and 1965. The incidence of injury due to the same cause were 34.0 for 1955 and 35.9 for 1965. 2. Death rates by transportation vehicle showed 9.0 due to motor vehicle accidents, 1.7 due to water-crafts, and 1.6 due to railway trains for 1955. In 1965 death rates were 6.0 due to motor vehicles, 1.2 to water-crafts and 2.4 to railway. 3. Seasonal distribution of transport accidents revealed that car accidents occur more frequently in spring and fall seasons while ship accidents do in winter and train accidents more in summer. 4. Both car and ship accidents slightly decreased during the past decade, 1955-1965, whereas the accidents of railway trains showed a tendency of increase. 5. Although the survey on railway accidents excluded the injuries of passengers or railway employees corresponding to WHO classification of diseases, E801, due to inaccuracy of data, it is roughly estimated that the same number of causalities as the incidence among pedestrians or any other than passengers or employees assumed to be at work(E 802).

The purpose of this paper is to review the colonoscopic fingings of twenty two patients with colonic tuberculosis which were diagnosed by colonoscopic finding, histopathology, and follow-up observation after antituberculosis chemotherapy at Pusan National University Hospital from January 1992 to December 1994. The results were as follows: 1) The male to female ratio was 1: 1.2, and the average age of the patients was 39.4 years with a slight predominance in women. The age of peak incidence was the 4th decade 40.9%). 2) Abdominal pain(95%), diarrhea(63%), and weight loss(50%) were the most common clinical findings. Others were constipation, melena, and palpable abdominal mass. The location of the pain was right lower abdomen, epigastrium, central abdomen, and left lower abdomen in decreasing order. 3) Hematologic findings showed decrease in hemoglobin level, increase in ESR, and positive CRP(61.5%). The white blood cell counts were mostly normal. 4) The stool examination showed positive occult blood in 7 cases among 18 cases (38.9%). Acid-fast bacteria was observed in stool of one case. 5) On colonoscopy, the lesion sites were ileoeecal valve(75%), ascending colon(72.7 %), terminal ileum(52.6%), cecum(42.9%), transverse colon(31.8%), descending colon (27.3%), sigmoid colon(9%), and rectum(9%) in decreasing order of frequency. Most of them involved ileocecal area. 6) On colonoscopy, the shape of ulcer revealed circular(41%), fusion(36%), and irregular pattern(18%). It found skipped area in 9 cases, pseudopolyp in 8 cases, patency of ileocecal valve in 5 cases, and severe deformity of ileocecal valve in 6 cases. 7) Microscopic finding of biopsy specimens revealed noncaseating granulomatous inflammation in 12 cases, and nonspecific ulcerative inflammation in 10 cases. In conclusion the diagnostic yield may be greatly enhanced by obtaining multiple target biopsies frorn tbe deep portion of the ulcer bed and margins. Judged from the colonoscopic finding and clinical improvement after antituberculosis chemotherapy, more accurate diagnosis can be acquired.

Studies of the pathophysiology of intracranial artery following vasospasm remains yet incomplete. The present investigation was undertaken for the purpose of elucidating ultrastructural changes in the cerebral arterial wall sequentially from 1 hour to 24 hours following subarachnoid hemorrhage. Experimental vasospasm was induced by injecting autogenous blood into the cisterna magna of cats. The following observations were made : 1) One hour after the induction of subarachnoid hemorrhage, endothelial cells in the intima became more round and their cellular surface was markedly corrugated, these changes culminated at 7 to 24 hours with intimal thickening(due to subendothelial tissue). 2) In the media, the smooth muscle cells were most consistently and severly affected showing degeneration of mitochondria and vacuoles containing fine particles. 3) Twelve hours following SAH, some endothelial cells in the intima were displaced or seemed to have partially broken apart from the adjoining cells. On the basis of the above findings, it was concluded that the ultrastructural changes in the cerebral arterial wall was observed after the induction of SAH with normal cat's blood occurred as a consequence of vasospasm of the intracranial arteries.

The Journal of the Korean Orthopaedic Association 2025;60(1):38-45
Purpose:
Intertrochanteric fractures often involve comminuted fractures, particularly around the intertrochanteric ridge, including the greater and lesser trochanters. In cases with comminuted fractures in the posterior region, maintaining a stable reduction of the anteriormedial region of the fracture surface is essential. Therefore, this study examined the morphologic features of the anterior femur for stable reduction by analyzing the anterior region of intertrochanteric fractures using three-dimensional computed tomography.
Materials and Methods:
This retrospective study analyzed the imaging data of 51 patients aged 60 years and older who underwent a surgical treatment for intertrochanteric fractures at a single institution from April 2013 to March 2023. The sample contained 15 male patients with an average age of 81.9 years and 36 female patients with an average age of 83.7 years. Forty patients (78.4%) had two or more comorbidities. The bone mineral density was assessed in all cases except for five (9.8%).
Results:
In 49 cases (96.1%), the anterior fracture line followed the intertrochanteric line and passed through two bony prominences.In two cases (3.9%), the fracture line ran below the intertrochanteric line and involved a large fragment of the lesser trochanter. As the fracture line passed through the inferior medial bony prominence, it exhibited an S-shaped pattern rather than a straight line. The inferior medial bony prominence consisted of cortical bone, with an average thickness of 6.4±1.4 mm, which was significantly thicker than the surrounding average cortical bone thickness (1.5±0.6 mm) but thinner than the cortical bone thickness of the femoral shaft (7.3±1.3 mm).The fracture line in the superior lateral region of the intertrochanteric line included cancellous bone with a cortical bone thickness of 1.1±0.6 mm, which was thin.
Conclusion
The anterior fracture line followed the femoral intertrochanteric line and curves as it passed through the inferior medial bony prominence. The inferior medial bony prominence, consisting of cortical bone, was significantly thicker than the surrounding average cortical bone.

Benzodiazepine derivatives, chlordiazepoxide(Librium), diazepam(Valium), nitrazepam(Mogadon) and oxazepam(Serenid-D) are mainly used as hypnotics at present. Diazepam has been used mainly for premedication in anesthesia and as an intravenous anesthetic agent. The pharmacological actions of these drugs are tranquilizing effects for central nervous system, slight depression on the cardiovascular and respiratory system, anticonvulsant, anxiolytic and antidepressant effects. A new benzodiazepine derivative, Flunitrazepam(Ro 5-4200) has strong hypnotic action, is anticonvulsant and antidepressant in spite of slight depression of the cardiovascular and respiratory systems. Furthermore the onset and duration of this drug are shorter than the others. In our clinical study, flunitrazepam in the dosage of 0.005mg/kg was administered intravenously, as an intravenous anesthetic induction agent, for 22 surgical adult patients. In each patient, the blood pressure, pulse rate, respiratory rate, minutes volume and arterial gas study were done, before and after administration of the Ro 5-4200. The results are as follows; 1. Dosage of this flunitrazepam is not constant as other benzodiazepines. 2. The effects of flunitrazepam on the cardiovascular system showed slight depression but no effect by one hour post-operation. 3. In respiratory system, the minute volume was depressed slightly and the respiratory rate was increased but negligibly. 4. Undesirable side effects attributed to this drug were not found, except the developing of cough (one case).

Craniometaphyseal dysplasia is a rare bone disorder of unknown etiology characterized by overgrowth of the craniofacial bones and abnormal remodeling of the metaphyses. This disease can be sporadic or transmitted by autosomal dominant and recessive modes of inheritance, with recessive cases being more severe. Excessive net bone formation leads to frontal and paranasal bossing, hypertelorism, extremely broad and flat nasal bridge with a saddle deformity, lacrimal duct obstruction, paranasal sinus and mastoid obliteration, compression of cranial nerves, with resultant loss of vision, strabismus, facial paralysis, and deafness. Also, abnormal bone remodeling results in widening in the metaphyses of the long tubular bones, giving the appearance of an Erlenmeyer flask. We present a sporadic case of craniometaphyseal dysplasia associated with the facial paralysis observed in a 4 year-old female, emphasizing the importance of early detection of accompanying lesions for proper management.
