Blood sugar levels were measured in patients anesthetized with halothane and compared to those with Thalamonal. The effect of preoperative starvation, surgical and anesthetic tension and postoperative pain on the level of blood sugar were also studied. The results were as follows: 1) None of the patient has showed hypoglycemia of under 60mg% by 10~14 hours of fasting before anesthesia. 2) Preoperative apprehension or anxiety without premedication had not seemed to raise the blood sugar level. 3) At 15 minutes after induction, increase in blood sugar level was remarkable in Thalsmonal group, while it was insignificant in halothane group(p<0.01). 4) At 5 minutes after skin incision, there was again a remarkable increase in blood sugar level in Thalsmonal group and insignificant change in halothane group. 5) At 1 hour after induction, blood sugar level has increased significantly in both group(p<0.01). 6) At 30 minutes after termination of anesthesia, blood sugar levels were significantly high compared to preoperative levels. 7) There was no significant difference in change in blood sugar level between two groups. 8) Conclusively, surgery and/or anesthesia regardless of agents could be stressful enough to cause elevation of blood sugar level but it did not seem to cause clinically significant hyperglycemia because all the blood sugar values obtained from this study were within 60 to 200mg%.

PURPOSE: To Analyze the Clinical Results of the Total Knee Arthroplasty without Patellar Resurfacing. MATERIALS AND METHODS: One hundred and eight Total Knee Arthroplasties (Nexgen(R), Zimmer, USA) without resurfacing of the patella, were performed between February 1995 and September 1999, and 89 cases followed up for more than 36 months were analyzed in this study. The follow up period ranged from 36 to 70 months (average 52 months). The diagnosis was degenerative joint disease in 83 cases (93%), rheumatoid arthritis in 5 cases (6%) and avascular necrosis of medial femoral condyle in 1 case (1%). The clinical results were evaluated according to Knee Society Clinical Rating System. RESULTS: The mean preoperative knee score was 34 points (range 5-63 points) according to the Knee Society Clinical Rating System, and the mean preoperative functional score was 38 points (range, 10-61 points). The mean postoperative knee score was 91 points (range 65-98 points) and the mean postoperative functional score 89 points (range, 63-100 points). The current study shows that patellar complications associated with unresurfacing did not occur, with the exception of 2 cases of persistent peripatellar pain, which resolved by a postoperative 6 months with conservative treatment. The patellofemoral joint space was also well preserved even at the 3 and 5 year follow-ups. CONCLUSION: Complications of total knee arthroplasty, such as patellar dislocation or subluxation, rupture of the patellar tendon, and fracture of the patella, can be avoided by not resurfacing the patella. On the basis of our results, there is little evidence to support routine patellar resurfacing in total knee arthroplasty.

Cyclospora cayetanensis is an apicomplexan protozoan and is one of the most common pathogens causing chronic diarrhea worldwide. Eight stool samples with diarrheal symptom out of 18 Korean residents who traveled to Nepal were obtained, and examined for 25 enteropathogens including 16 bacterial species, 5 viral species, and 4 protozoans in stool samples as causative agents of water-borne and food-borne disease. Only C. cayetanensis was detected by nested PCR, and 3 PCR-positive samples were sequenced to confirm species identification. However, the oocysts of C. cayetanensis in fecal samples could not be detected by direct microscopy of the stained sample. As far as we know, this is the first report of a group infection with C. cayetanensis from a traveler visiting Nepal, and the second report of a traveler’s diarrhea by C. cayetanensis imported in Korea.

Objective: Patients recovering from moderate-to-severe coronavirus disease 2019 (COVID-19) reportedly have dysphagia or difficulty in swallowing. The current study compares the differences in dysphagia characteristics arising from COVID-19 pneumonia and aspiration pneumonia. We further identify factors affecting the severity of dysphagia. Methods: Fifty-four patients diagnosed with COVID-19 pneumonia with dysphagia and 44 patients with aspiration pneumonia were referred for a videofluoroscopic swallowing study (VFSS) since they presented with signs and symptoms of dysphagia. The electronic medical records were reviewed to compare the dysphagia characteristics of the patients. Results: Intensive care unit (ICU) admission, intubation, tracheostomy, and a diagnosis of Acute Respiratory Distress Syndrome (ARDS) after admission were more common in patients with COVID-19 pneumonia (P＜0.001 for other variables and P=0.007 for tracheostomy) than in patients with aspiration pneumonia. Compared to patients with aspiration pneumonia, the COVID-19 patients had a significantly higher total modified videofluoroscopic dysphagia scale (mVDS) score, indicating more severe dysphagia (P=0.038). Among the mVDS sub-scores, tracheal aspiration was significantly higher in the COVID-19 pneumonia group (P＜0.001). In logistic regression analysis, age (P=0.034), COVID-19 (P=0.001), ICU admission (P=0.012), tracheostomy (P=0.029), and ARDS diagnosis after admission (P=0.036) were significantly associated with tracheal aspiration. After adjusting for age, sex, comorbidities, and clinical variables, COVID-19 was still significantly associated with worse tracheal aspiration scores (P=0.042). Conclusion Patients with COVID-19 pneumonia showed more severe dysphagia than subjects with aspiration pneumonia. This is particularly related to tracheal aspiration, as revealed by the VFSS. The dysphagia also correlated with a greater incidence of ICU admission, intubation, tracheostomy, and ARDS diagnosis in the COVID-19 pneumonia group.

OBJECTIVE: We studied whether frontal skull base fracture has an impact on the occurrence and recovery of anosmia and/or ageusia following frontal traumatic brain injury (TBI). METHODS: Between May 2003 and April 2005, 102 consecutive patients who had hemorrhage or contusion on the frontal lobe base were conservatively treated. Relevant clinical and radiographic data were collected, and assessment of impaired smell and taste sensation were also surveyed up to at least 12 months post-injury. RESULTS: Among 102 patients, anosmia was noted in 22 (21.6%), of whom 10 had ageusia at a mean 4.4 days after trauma. Bilateral frontal lobe injuries were noted in 20 of 22 patients with anosmia and in all 10 patients with ageusia. Frontal skull base fracture was noted in 41 patients, of whom 9 (21.4%) had anosmia and 4 (9.5%) had ageusia. There was no statistical difference in the occurrence of anosmia and ageusia between patients with or without fracture. Of the 22 patients with anosmia, recovery from anosmia occurred in nine (40.9%) at the interval of 6 to 24 months after trauma, of whom six had frontal skull base fracture and three were not associated with fracture. Recovery of anosmia was significantly higher in patients without fracture than those with fracture (p<0.05). Recovery from ageusia occurred in only two of 10 patients at the interval of 18 to 20 months after trauma and was not eminent in patients without fracture. CONCLUSION: One should be alert and seek possibile occurrence of the anosmia and/or ageusia following frontal TBI. It is suggested that recovery is quite less likely if such patients have fractures on the frontal base, and these patients should wait for at least 6 to 18 months to anticipate such recovery if there is no injury to the central olfactory structures.

BACKGROUND: Cilostazol leads to inhibition of platelet aggregation and to vasodilatation. It is widely used for the secondary prevention of cerebral infarction. However, headache is a well-known adverse effect of cilostazol, and these headaches may be caused by the vasodilation of the cerebral artery. The goal of our study was to assess the frequency and severity of headaches following cilostazol treatment and to evaluate factors related to the development of these headaches. METHODS: Seventy patients with cerebral infarction were included in this study. We measured the carotid intima media thickness (IMT), the distensibility of the carotid artery (CAD), the brachial ankle index (ABI), and the brachial ankle pulse wave velocity (PWV) in order to quantify the degree of atherosclerosis and arterial stiffness. Patients were then given 100 mg of cilostazol in tablet form twice daily. For three days, we evaluated headache incidence and severity using a verbal rating scale (0-10). RESULTS: Twenty three (32.9%) patients reported headache during cilostazol medication and 7 patients had severe headache. Women were more likely to develop headaches than men (p=0.03). In addition, the mean IMT was lower in subjects with cilostazol-induced headache than in the headache-free subjects (0.8+/-0.1 vs 1.01+/-0.2 mm, p=0.001), while CAD was higher in these subjects (0.3+/-0.1 vs 0.25+/-0.1, p=0.03). There was no difference in PWV and ABI. CONCLUSIONS: Lower carotid IMT, increased CAD, and female gender may be associated with the development of cilostazol-induced headache in patients with cerebral inafarction, but not the systemic arterial stiffness.

OBJECTIVE: There are numerous reports on the primary stabilizing effects of the different cervical cages for cervical radiculopathy. But, little is known about the subsidence which may be clinical problem postoperatively. The goal of this study is to evaluate subsidence of cage and investigate the correlation between radiologic subsidence and clinical outcome. METHODS: To assess possible subsidence, the authors investigated clinical and radiological results of the onehundred patients who underwent anterior cervical fusion by using AMSLUTM cage during the period between January 2003 and June 2005. Preoperative and postoperative lateral radiographs were measured for height of intervertebral disc space where cages were placed. Intervertebral disc space was measured by dividing the sum of anterior, posterior, and midpoint interbody distance by 3. Follow-up time was 6 to 12 months. Subsidence was defined as any change in at least one of our parameters of at least 3 mm. RESULTS: Subsidence was found in 22 patients (22%). The mean value of subsidence was 2.21 mm, and mean subsidence rate was 22%. There were no cases of the clinical status deterioration during the follow-up period. No posterior or anterior migration was observed. CONCLUSION: The phenomenon of subsidence is seen in substantial number of patients. Nevertheless, clinical and radiological results of the surgery were favorable. An excessive subsidence may result in hardware failure. Endplate preservation may enables us to control subsidence and reduce the number of complications.

To investigate the therapeutic effect of ciprofloxacin for the treatment of endophthalmitis, we used 18 rabbits with Staphylococcus aureus induce dendophthalmitis. The rabbits were assigned into three groups according to the treatment regimen; those who were not given any drug into group I, those who were given 100 microgram/ml ciprofloxacin intrvitreally into group II, and those who were given 2 mg/ml ciprofloxacin subconjunctivaly for 5 days into group III. We assessed clinical score, culture result of vitreous aspirate and pathologic finding of various ocular tissue. We found clinically significant decrease in clinical score in group II, but there were no significant differences in the vitreous culture and in the histologic findings among the study groups. In conclusion, we assume that intravitreal injection of ciprofloxacin may be the better treatment modality to treat endophthalmitis by S.aureus. In addition we still think there ought to be more studies as to the determination the dosage of ciprofloxacin and the use of steroid in combination.

Patients with achondroplasia manifest various neurologic symptoms including megaencephaly, hydrocephalus, and progressive myelopathy or radiculopathy secondary to spinal stenosis. However, only anecdotal postmortem reports proved ruptured aneurysm or vascular malformation as a source of intracranial hemorrhage. We herein report a case of a 26-year-old woman with achondroplasia who underwent uneventful surgical treatment for the aneurysmal subarachnoid hemorrhage. In this literature, we review the pathophysiologic mechanism and emphasize the necessity of considering the possibility of sudden mental deterioration in achondroplastic patient.
