Background: Many countries need help with the problem of an unbalanced distribution of physicians and hospitals. Moreover, various policies and strategies have been proposed to solve this problem. This study aimed to examine the determinants of the unbalanced distribution of physicians. Methods: From the 2020 Korean Physician Survey data, 4,181 physicians practicing in Korea were limited to the subjects of the study. We analyzed the factors influencing physicians’ choice of practice location and their willingness to change their practice location from an urban to a rural area. Results: The region of physicians’ hometown, medical school, and residency training hospitals determined their choice of practice location. The type of affiliated healthcare organization and the location of physicians’ hometown, medical school, and residency training hospitals affected their willingness to change their practice location from an urban to a rural area. Furthermore, the concordance rate of the regions of physicians’ hometown, medical school, and residency training hospitals with the region of their practice location was 24.9%. Conclusion In South Korea, policies for doctors have been designed without considering why they are reluctant to work in rural hospitals. To have a balanced distribution of physicians and hospitals, it is necessary to accurately analyze the status of medical resources based on regions and identify the current and future medical demand. The social situation, such as future demographic change and regional extinction, must also be fully considered. Furthermore, policies should be implemented that encourage physicians to work in rural hospitals.

STUDY DESIGN: This is a retrospective study that focused on the perioperative complications when performing posterior arthrodesis for treating degenerative lumbar disorders in elderly patients. OBJECTIVES: We wanted to analyze the perioperative risk factors and the complications associated with posterior lumbar decompression and arthrodesis in patients who were sixty-five years of age or older. SUMMARY OF LITERATURE REVIEW: Lumbar arthrodesis is commonly done in elderly patients to treat degenerative spine problems. These patients may be at an increased risk for complications because of their age and their associated medical conditions. MATERIALS AND METHODS: We studied 111 patients who were over 65 years old and they were able to be followed up for more than 3 months after performing posterior arthrodesis during the recent 5 years. Sixty-one patients who had undergone posterolateral fusion (PLF) were classified as group A, and 50 patients who had undergone posterior lumbar interbody fusion (PLIF) using a PEEK cage were classified as group B. We analyzed their rates of complications and the causative factors, according to operative methods and age, and these complications occurred within 12 weeks after the operations. RESULTS: Complications occurred for 43 patients of group A, and for 26 patients of group B. The differences in the rates of complications were statistically significant, and group A had a more complications than did group B. The relations between medical problems and the incidence of perioperative complications were statistically significant for both groups. CONCLUSIONS: Elderly patients with medical problems should be made aware that they are at an increased risk for surgical complications, and attention hould be paid to controlling the blood loss and limiting the operative time. The PLIF using a PEEK cage was identified as a procedure that could reduce the perioperative complications.

PURPOSE: To report a case of bilateral acute myopia and angle-closure with ciliochoroidal detachment in Vogt-Koyanagi-Harada (VKH) syndrome. CASE SUMMARY: A 43-year-old Korean woman diagnosed with VKH syndrome underwent intravenous methylprednisolone steroid pulse treatment. After oral medication was given for 2 days, the anterior chambers became shallow in both eyes. Intraocular pressure (IOP) increased to 25 mm Hg in the right eye and 23 mm Hg in the left eye. Subretinal fluid increased and visual acuity decreased with myopic shift in both eyes. IOP did not decrease despite maximum tolerated medical therapy. Ultrasound biomicroscopy (UBM) revealed that ciliochoroidal effusion caused forward displacement of the lens-iris diaphragm, which resulted in anterior chamber shallowing and angle closure in both eyes. The patient was treated with cycloplegic eyedrops and intravenous steroid pulse therapy. After intravenous steroid pulse treatment was given for 2 days, the anterior chambers became deep in both eyes. IOP reduced to 13 mm Hg and 14 mm Hg in the right and left eye respectively. Visual acuity increased with normalization of myopic shift. UBM revealed that the ciliochoroidal effusion had resolved in both eyes.

Nedocromil sodium is an anti-inflammatory medication for the treatment of mild to moderate asthma. The most common side effect of the nedocromil sodium is an unpleasant and bitter taste. However it is rare, less than 3%, to stop the treatment because of this side effect. Other side effects includes cough, headache, throat irritation and nausea which are reported as mild and transient. A 7-year-old female had a severe headache and dizziness during the treatment of asthma with nedocromil sodium. The symptoms subsided after nedocromil sodium was replaced by budesonide. We experienced a case of a severe headache and dizziness due to nedocomil sodium that lead to withdraw of the nedocromil sodium.

BACKGROUND: Estrogens act on estrogen receptors distributed in articular cartilages, synovial membrane, and ligaments, which are thought to be related with degenerative changes. Meanwhile, progesterone is known to have a weak anabolic action on bone formation This study evaluates the effects of estrogen and progesterone hormone on bone/cartilage turnover in ovariectomized (OVX) rats. METHODS: Thirty-five 7-month-old female Sprague-Dawley rats were randomly divided into 5 groups and then ovariectomized bilaterally except the sham control group. The first and the second group acting as controls did not receive hormonal therapy, the third group received estrogen, the fourth group received progesterone, and the fifth group received combination of both hormones 10 weeks after surgery. Evaluations were done using the serum levels of cartilage oligomeric matrix protein (COMP) for cartilage turnover, collagen type I C-telopeptide (CTX-1) and osteocalcin (OC) for bone turnover at 11, 15, 19 weeks after OVX and histology using the Osteoarthritis Research Society International (OARSI) osteoarthritis (OA) cartilage histopathology assessment system. RESULTS: Significantly less cartilage degradation (decreased levels of COMP) was found in the combined hormone treated group in comparison with OVX group. Similarly, both hormonal treatment resulted in increased bone formation and decreased bone resorption i.e., a low overall bone turnover status (decrease in the serum OC and CTX-1 levels). CONCLUSIONS: Combined estrogen and progesterone therapy was found to be convincing in terms of reducing the severity of OA in this experimental model.

BACKGROUND: It is well known that opioids induce coughing. Many drugs such as lidocaine and ketamine are used to effectively prevent the coughing induced by opioids and this has been revealed to be effective. In this study, we evaluated the preventive effect of a graded escalation of the remifentanil concentration using a target controlled infusion pump and we compared this with the effect of lidocaine. METHODS: One hundred fifty ASA I and II patients who were scheduled for elective surgery were randomly divided into 3 groups. The patients were pretreated with 2% lidocaine 1 mg/kg (Group L) or saline (Group S) and remifentanil infusion (an effect site concentration of 4.0 ng/ml) was followed 1 minute later by using a target controlled infusion pump. Group R was pretreated with saline and this was followed by remifentanil infusion (effect site concentration of 2.0 ng/ml at first and then it was reset to 4.0 ng/ml). We evaluated the incidence, severity and onset time of cough after remifentanil infusion. RESULTS: The incidence of coughing was significantly decreased in Group R (6 cases, 12%) and Group L (7 cases, 14%), as compared to that of Group S (17 cases, 34%) (P < 0.05), but there was no significant difference between Group R and Group L. The groups showed no significant difference in the severity and the onset time of coughing. CONCLUSIONS: This study demonstrated that administering graded escalation of the remifentanil concentration suppresses remifentanil-induced coughing as effectively as lidocaine 1 mg/kg pretreatment.

PURPOSE: Neutrophils found around an infarcted area in the brain was once considered as only the physiologic response following the brain injury, but recent studies have shown that inflammatory responses by neutrophils play an important role in the reperfusion injury. The presence of polymorphonuclear leukocytes(PML) is proven by biochemical assay of myeloperoxidase(MPO) secreted in the cytoplasmic granules. We observed the process of PML infiltration on hypoxic-ischemic brain injury of immature rats by the assay of MPO activity and changes of the MPO activity after the administration of fucoidin, inhibitor of P- and L-selectin. METHODS: We used a well characterized model of the brains of 7 day-old-rats, which had unilateral hypoxic and ischemic injuries(HI). Those injuries were induced by unilateral carotid artery ligation followed by timed exposure to hypoxic inspiratory gas mixture(8% O2). MPO activity was measured in the brain tissue homogenates of HI rats(n=18) at 0, 2, 8, 24 and 48 hrs and in rats that received fucoidin immediately before and again after hypoxia(50 mg/kg, n=6) at 8 and 24 hrs. Controls(n=2) were rats with neither hypoxia nor ischemia. The brain samples were homogenized in 20 mM potassium phosphate buffer(pH 7.4) for 50 secs. The homogenate was centrifuged at 14,000 g at 4degrees C for 15 mins and the supernatant was discarded. The tissue was pulverized, weighed, and suspended in 1 mL of 50 mM potassium phosphate buffer solution(pH 6.0) containing 0.5% cetylditrimethylammonium bromide(wt/vol). The tissue was sonicated and centrifuged at 10,000 g for 15 mins. 200 micro L of the supernatant was mixed with 1 mL of 50 mM potassium phosphate buffer solution(pH 6.0) containing 10 micro L of 1.325 mM o-dianisidine hydrochloride and 170 micro L of 3% hydrogen peroxide(vol/vol). Changes in absorbance at 460 nm were measured for 5 mins by using microplate reader. One unit of MPO activity was defined as that degrading 1 micro mol peroxide/min at 25degrees C, and the result was expressed as units of MPO/100 mg tissue. RESULTS: In HI rats, MPO activity increased at 2 hrs after HI and peaked at 24 hrs in the right hemisphere. In rats with fucoidin treatment immediately before and again after hypoxia, the MPO activity significantly decreased in both hemispheres compared with HI rats(P<0.05). MPO activity in the tissue of control rats was insignificant. CONCLUSION: The dynamic changes of the MPO activity suggest the important role of PMN on hypoxic-ischemic brain injuries in immature rats. MPO activity could be used as an index of the severity of injuries of hypoxic-ischemic brains.

PURPOSE: The selectin family of adhesion molecules plays a role in the initiation of endothelium-leukocyte interaction of inflammation and ischemia-reperfusion. P-selectin, a rapidly expressed endothelial cell adhesion molecule, is essential for both neutrophil rolling after endothelial stimulation and neutrophil transmigration. P-selectins were expressed after brain injury and could play an important role in the pathogenesis of ischemic brain injury in adult animal. However, the mechanisms leading to post-hypoxic-ischemic injury in immature brain are unknown yet. We hypothesize that P-selectin might mediate post-hypoxic-ischemic injury in immature rat brain. We evaluated the expression of mRNA and protein of P-selectin in post-hypoxic-ischemic immature rat brain. METHODS: In isoflurane-anesthetized P7(Postnatal day 7) Sprague-Dawley rats(n=81), the right carotid artery was isolated and coagulated. 1-2 h later animals were exposed to 8% oxygen(balanced with nitrogen) for 2 h in glass chambers, in a warm air incubator (temperature maintained at 36.5 degrees C). Control included carotid artery coagulation alone, hypoxia alone, and normal(neither hypoxia nor coagulation). For RNA extraction, the rats were decapitated at 0, 2, 4, 8, 12, 24 and 48 h after hypoxic-ischemic injury. For Western blot analyses with P-selectin, rats were decapitated at 0, 15, 30 min, 1, 2, 4, 8, 12, 24 and 48 h after hypoxic-ischemic injury. Control or hypoxia alone rats were sacrificed 8 h after the respective intervention. RESULTS: There was no expression of P-selectin mRNA in control groups(carotid artery coagulation alone, hypoxia alone, or normal). P-selectin mRNA expression in the ipsilateral(right) hemisphere reached a peak at 8 h after hypoxia-ischemia and then barely detected after 24 h. Expression of P-selectin protein was not observed in brain tissue of control rats. P-selectin protein was detected as early as 15 min and 30 min at both hemisphere in experimental rats and decreased at 1 h. P-selectin protein increased in right hemisphere at 4 h post-hypoxia-ischemia, peaked at 8 h and no longer detectable at 24 h. CONCLUSION: Hypoxic-ischemic injury leads to P-selectin expression in neonatal rats brain. The temporal profiles of post-hypoxic-ischemic P-selectin mRNA and protein expression are consistent with a role in the evolution of subsequent brain injury.

BACKGROUND: Hypertension in the immediate postoperative period, if sufficiently high, can cause left heart failure, arrhythmia, myocardial infarction, and cerebral hemorrhage. The causes of postoperative hypertension are hypertension history, pain, hypoxia, emergence excitement, reaction to endotracheal tube, hypothermia, excess fluid administration, hypercarbia, etc. To know the predictable factors for the postoperative hypertension the authors tried to investigate perioperative patient care of the postoperative hypertensive cases. METHODS: One hundred twenty surgical patients in both sexes between the age of 40~60 were sampled randomly and devided into two groups. The normotensive (N) group included the patients with postoperative blood pressure below 140/90 mmHg and the hypertensive (H) group, above 140/90 mmHg. The incidence of hypertension history, hypertension on admission, hypertension on ward, change of systolic blood pressure above 20% during surgery, intra or postoperative use of antihypertensives or inotropic agents were compared between the groups. RESULTS: The incidence of history of hypertension was higher in H group (20%) than N group (6.7%). Hypertension on admission was higher in H group (43.3%) than N group (23.3%). Systolic blood pressure change above 20% was only in H group (6.7%). Use of antihypertensive was more frequent in H group (33.3%) than N group (3.3%) and use of inotropic agents was only in N group (8.3%). The blood pressure at ward, preinduction, and after induction were higher in H group. Within the group the blood pressure between preinduction and after induction has no difference. CONCLUSION: Immediate postoperative hypertension can be expected in case of history of hypertenion, hypertension on admission (above 140/90 mmHg), change of systolic blood pressure above 20%, use of antihypertensive during operation, and hypertension just before induction.

Marfan syndrome (MFS) is an inherited connective tissue disorder with a mutation in the fibrillin-1 (FBN1) gene. Fibrillin is a major building block of microfibrils, which constitute the structural component of the connective tissues. A 10-year-old girl visited our hospital with the chief complaint of precocious puberty. According to her medical history, she had a pulmonary wedge resection for a pneumothorax at 9 years of age. There was no family history of MFS. Mid parental height was 161.5 cm. The patient's height was 162 cm (>97th percentile), and her weight was 40 kg (75th-90th percentile). At the time of initial presentation, her bone age was approximately 11 years. From the ophthalmologic examination, there were no abnormal findings except myopia. There was no wrist sign. At the age of 14 years, she revisited the hospital with the chief complaint of scoliosis. Her height and weight were 170 cm and 50 kg, respectively, and she had arachnodactyly and wrist sign. We performed an echocardiograph and a test for the FBN1 gene mutation with direct sequencing of 65 coding exons, suspecting MFS. There were no cardiac abnormalities including mitral valve prolapse. A cytosine residue deletion in exon 7 (c.660delC) was detected. This is a novel mutation causing a frameshift in protein synthesis and predicted to create a premature stop codon. We report the case of a patient with MFS with a novel FBN1 gene missense mutation and a history of pneumothorax at a young age without cardiac abnormalities during her teenage years.
