For the nonunion of humeral shaft, there have been many methods of treatment. We are aimed to analyse the causes of nonunion of humeral shaft fracture and present the direction of treatment. We reviewed total 21 cases which were diagnosed as delayed or nonunion of humeral shaft and analysed the causes. l. Initial method of treatment was surgical in 19 out of 21 cases. Among these 19 cases, 14 cases were operated with internal fixation with plate and screw. 2. The most common cause of nonunion was inadequate internal fixation in 26 cases(81%) in which were unstable fixation in 13 cases, choice of inadequate internal fixator in 11 cases, and failure of operative technique in 2 cases. Other causes were distraction between fracture fragments in 4 cases(13%) and open comminuted fracture in 2 cases. 3. Eighteen cases of established nonunion due to inadequate internal fixation were treated by rigid fixation with longer and broader plate and bone graft, and 1 case interlocking IM nailing, 1 case Ender nailing and 1 case bone graft only. 4. Union was obtained in all cases at least in 5 months. And there were no specific complications. In conclusion, surgeons should contemplate the operative indication and principles in primary treatment. In treatment of nonunion, surgeons should treat by more longer and broder internal fixator and additional bone graft.

A 69-year old female, complaining of severe ocular pain, marked proptosis, and severe congestion of one eye, was found to have an extensive thrombophlebitis of the orbit. The cause and pathogenesis of this process were undetermined. Authors report a case of idiopathic thrombosis of orbital veins. A review of literature related to this disease was added.

Tretinoin(all-trans retinoic acid) is a metabolite of vitamin A and it is useful in the treatment of photoaging skin. Photoaging skin is characterized by wrinkles, mottled pigmentation, dry and rough skin, and loss of skin tone. Current use of topical tretinoin mainly acts on the epidermis, requires a long period to obtain the desired results and may cause skin hyperpigmentation. A combination of topical and injectable tretinoin has been used to reduce the treatment period as a result of its potentialized effect on the dermis when compared to graditional topical cream use. in this study, we observed histologic alterations in 5 white rabbits after using 0.05% topical tretinoin cream and 0.1% injectable tretinoin. Tretinoin was treated on the rabbits ears-group 1 and 2 on the right ear for study 1, and group A and B on the left ear for study 2. Study 1 was done to differentiate whether the dermal thickening is due to the simple physical stretching of dermis by intradermal injection, or whether it is duer to the histologic change by tretinoin. In group 1, saline was injected intradermally and in group 2, tretinoin was injected intradermally. Study 2 was done to compare the dermal thickening between the topical tretinoin cream treatment group (group A) and the combined topical and injectable tretinoin group (group B). Injection was done once a week immediately followed by 340nm blue light skin exposure. These treatment were done for 12 weeks. We harvested skin stripe from all group, group 1 and 2, and group A and B respectively, after 2, 6, and 12 weeks after treatment. Histologic differences were observed and measured. Dermal thickening was observed in group 2 and in group B(p<0.05). The results showed that intradermal injection of tretinoin mainly acts on the dermis and potentialtes the effect on photo-aging skin and fine wrinkles.

In infected uncemented hip arthroplasty, 4 cases which showed well-fixed femoral stem were managed by staged procedure. Thorough debridement, removal of acetabular socket and insertion of antibiotics impregnated cement spacer was done without removal of femoral stem. No recurrence of infection or loosening was developed after staged procedure and revisoin was performed after infection evidence disappeared. The interval between the two procedures was 4 months (3-6) on average. In Weber's criteria, all 4 cases were graded as having definitive cure of infection on both clinical and radiological criteria (Grade I) .

To evaluate the antihypertensive effects of serotonin antagonist, ketanserin, a daily dosage of 10~40mg (18.9+/-6.8 mean+/-SE) was administered to 22 patients with essential hypertension and aged 55??1 years (64+/-7.7 mean+/-SE) for 12 weeks. After 12 weeks of ketanserin treatment mean blood pressure decreased from 177.9+/-11.9 to 15.7+/-15.3mmHg in systole and from 104.2+/-7.4 to 88.4+/-7.9mmHg in diastole (P<0.001). There was no significant change in heart rates with ketanserin treatment. The antihypertensive treatment with ketanserin was effective in 18 patients(81.8%) and ineffective in 4 patients (18.2%). Adverse reactions such as drowsiness (8.7%), edama (4.3%) and weakness (4.3%) were noted, but all were mild and transient. This results suggest that ketanserin is an effective and safe antihypersive agent in the treatment of essential hyperension.

The authors interviewed with 21 North Korean defectors who detected from North Korea in 1990-1995 and investigated their adjustment to South Korean society. The main categories of their problems in adjustment were a poor social network, financial difficulties, problems in social competency, problems resulting from their indoctrinated way of thinking, some psychological problems such as excessive self-consciousness and guilty feelings, and some social-structural problems such as poor education system in the government shelter. But, generally speaking, inspite of their problems, they have adjusted to South Korea society rather successfully In the view of short term adjustment, the reasons for their success were thought to be the characteristics and merits of a capitalistic economy ; their compliant personalities resulting from an educational system that emphasized obedience to authority and Kim Il Sung, and the dualism of North Korean lifts. Four points were discussed to assist a successful adjustment in the long term ; Fostering of the ability to make individual choices with internal principles, overcoming a judgemental, moralizing attitude, overcoming of overfull thought centered attitude and rebounding thought-lacking attitude, overcoming the effect of negative collectivism. Three things have been suggested to foster their healthy adjustment ; development and running of resocialization program for the each period of settlement ; building up a network of accessible support organizations who work for the adjustment of defectors ; systemic studies of North Korean people and defecters for the successful adjustment to unified Korean society. It is said that the division of Korean people has been the most tragic thing happen to Korea. But there can be a greater tragedy and that would be the unification of land but not the unification of people. failure to understand the real problems of the North Korean population can potentially produce conflicts and confusion which can only lead to funker re-division and greater tragedy. It is very important to study the adjustment to problems of North Korean defectors to help prepare far the unification of the Korean people.

We present a case of severe intracranial hypotension syndrome following lumbar drainage. A 60-year-old woman developed recurrent attacks of vertigo, nausea and vomiting a week prior to admission. Brain MRI revealed a homogeneously well-enhanced mass in the right frontal lobe ; this was found to be a meningioma, and was totally removed. Dural defect was covered with fat and fascia, and postoperative cerebrospinal fluid(CSF) leakage through the frontal sinus was noted. Lumbar drainage was initiated, and about 36 hours later, the patient complained of bouts of headache, nausea and vomiting. Her mental state then gradually deteriorated, and she became stuporous. Brain CT was performed immediately and revealed bifrontal subdural fluid collection and signs of severe brain edema including obliteration of ventricles and basal cisterns. The lumbar drain was then clamped and she regained consciousness 12 hours later. This case clearly demonstrates that to avoid complications such as severe intracranial hypotension syndrome in a patient who has undergone lumbar drainage, the rate and amount of CSF drainage should be closely monitored.
