BACKGROUND: Sustained-release theophylline, which is generally prescribed as a twice-daily equal-dose regimen, is one of the more common asthma treatments. the development of a sustained-release drug delivery technology that enables improved control of the theophylline blood levels represents a significant advancement in both the efficacy and safety of dosing. METHOD: A crossover study was conducted with 25 adult chronic asthmatic patients requiring daily bronchodilator therapy. The study group included thirteen males and twelve females with ages ranging from 19 to 71 years. The overall approach was to place the patients first on the twice-daily preparation(Etheophyl®) for 28 days at 8 AM and 8 PM, and measure the pulmonary function and theophylline level on the 28th day. the patients were subsequently switched to the once-daily preparation(Uniphyl®) in the same daily dose at 8 PM on the 29th day and the same parameters were measured on the 56th day. RESULTS: the mean serum levels of theophylline were 8.18±1.66µg/ml in the Etheophyl®-treated period and 8.00±1.75µg/ml in the Uniphyl®-treated period. In addition, the FEV1 showed 71.40±7.48 percent in the Etheophyl®-treated and 69.18±9.00 percent in the Uniphyl®-treated period. Thus there were no significant differences between the once-daily and twice-daily preparation. CONCLUSION: The results indicated little clinical differences between the two medication. The two drugs are equally effective in controlling asthma over the four weeks of treatment.

Bicoronal approach is adopted as an universal method for reduction and internal fixation of the fractured zygomatic arch in the treatment of complex zygomatic fracture. However bicoronal approach leaves many disadvantages, such as long incision, alopecia, prolonged edema, and paresthesia. Nowadays endoscopically assisted minimal invasive technique has been widespread not only for the aesthetic surgery, but also for the reconstructive surgical fields because of the benefits. We have been recently trying to apply endoscopic surgery to facial bone fracture surgery. Endoscopically assisted minimal invasive technique has been applied to 14 patients who admitted to Chosun university hospital from March 1996 to July 1997. We used 4 mm, 30' endoscope and two 1.5-2 cm temple incisions and a subciliary incision for approaching to the zygomatic arch. Protected drill bit and driver had access to fractured zygomatic arch though tiny(5 mm) stab incision over the zygomatic arch. We have been able to successfully reduce and make fixation of the fracture of zygomatic arch by using endoscopically assisted minimal invasive technique. Follow up for 3 months revealed good maintenance of the reduction. We think that application of the endoscopic technology to midfacial bone fracture will result in significant reduction in morbidity and improve postoperative results.

We analysed a perceiving pain at each step (8 step: traction suture, wound incision, anterior capsulotomy, phacoemulsification, irrigation and aspiration, intraocular lens (IOL) implantation, wound suture, subtenon's injection) of cataract surgery by using visual analogue scale (0-10), prospectively. One hundred cases of cataract surgery were performed from November 1995 to March 1996 at Chonnam national university hospital and topical or retrobulbar anesthesia prior to cataract surgery was applied to each 50 patients. There was no difference of age, sex, running time for surgery, and incision method between topical and retrobulbar anesthesia. Pain scores at phacoemulsi fication. irrigation and aspiration, and subtenon's injection were higher than those at other steps in both types of anesthesia. However, a major range of pain scores at each step except of subtenon's injection was mild (1-3). In topical anesthesia, pain score was higher than retrobulbar anesthesia, but there was no statistically significant difference except a step of subtenon's injection. In conclusion, topical anesthesia might be an adequate anesthetic method for cataract surgery.

PURPOSE: To assess the efficacy and resulting complications of tetracycline sclerotherapy in renal, hepatic, ovarian, and perivesical cysts. MATERIALS AND METHODS: We retrospectively reviewed 23 cases of benign cysts (16 renal, 4 hepatic, 2 ovarian, and 1 perivesical) in 22 patients in whom the condition was diagnosed or confirmed by either ultrasound, CT, or cytology, and who underwent percutaneous tetracycline sclerotherapy. Using a 21-gauge Chiba needle, the target cyst was punctured under ultrasound guidance. Prior to the injection of 1500 mg of tetracycline diluted in 5 ml of normal saline, almost all the cystic content was aspirated, and at the end of the procedure the tetra-cycline was left in the cyst. During a period of between 3 and 22 months, 18 of the 23 cases were followed up. RESULT: In six of the 18 cases followed up, the cysts either decreased in size by 10%, or collapsed completely. In seven cases a collapse of over 50% was noted, and in the remaining five the cyst recurred. In one of these, complete collapse occurred after retreatment at ten months, and the patient with a perivesical cyst underwent surgery six months after recurrence. Thus, treatment was effective (a collapse of at least 50%) in 13 of 18 cases (72.2%). This total of 13 comprised ten of 12 renal cysts (83.3%), two of two ovarian (100%), and one of three hepatic (33.3%). Percutaneous therapy was unsuccessful in five cases (two hepatic cysts, one renal, one para-pelvic and one perivesical). Complications occurring during the procedure or follow-up period included discomfort or mild pain, vomiting, and transient fever, though these subsided within 24 hours. In one patient with severe pain, this subsided after four days. CONCLUSION: As single-shot injection of tetracycline provides safe and effective treatment for renal and ovarian cysts, but for hepatic cysts is unsuccessful.

Background: Acetabular fractures are rare and challenging to treat, and the surgeon’s learning curve for managing these fractures is steep. The incidence of acetabular fractures is low, making it difficult to conduct single-surgeon, single-center studies.Therefore, multi-surgeon and multi-center studies may produce inconsistent outcomes compared to those of single-surgeon, singlecenter studies. According to the authors’ literature investigation, single-surgeon, single-center, large-scale studies on this topic are lacking. Thus, this study investigated the radiological and functional outcomes and prognostic factors in patients with displaced acetabular fractures treated by a single surgeon at a single center and followed up for at least 1 year. Methods: This retrospective study was conducted on 149 patients treated for acetabular fractures at Chungbuk national university hospital between January 2005 and December 2021. Demographic data, time to surgery, and complications were collected using medical records. The Judet and Letournel classification was confirmed using preoperative radiographs, and Matta’s quality of reduction was confirmed using immediate postoperative radiographs. At the latest outpatient follow-up, Matta’s radiological outcome grading and the modified Postel Merle d’Aubigné score were confirmed as radiological and functional outcomes, respectively. Results: The radiological outcome was excellent or good in 131 patients (87.9%) and fair or poor in 18 (12.1%) and influenced by age (p = 0.009), quality of reduction (p < 0.001), and the Judet and Letournel classification (p = 0.025). Functional outcome was excellent or good in 121 patients (81.2%) and fair or poor in 28 (18.8%); this was influenced by the quality of reduction (p < 0.001) and the Judet and Letournel classification (p = 0.030). Conclusions Our radiological and functional outcomes of acetabular fractures were comparable with those of other singlesurgeon, single-center studies regarding the follow-up period. Poor prognostic factors for radiological outcomes included age > 65 years, associated patterns, and poor quality of reduction. Associated patterns and poor quality of reduction were factors associated with poor functional outcomes.

A-57-year-old male patient suddenly developed cramping pain in the left lower abdomen with a slight abdominal distension. He had undergone a laparoscopic nephrectomy for transitional cell carcinoma 7 days earlier. An abdominal CT scan revealed a dilated small bowel loop and an internal hernia was suspected. Surgery revealed a herniation of the jejunal loop through defects in the retroperitoneum, which was successfully reduced. We report a case of an internal hernia following a laparoscopic nephrectomy. To the best of our knowledge, this is the only reported case of an internal hernia as a complication of laparoscopic nephrectomy.

Broncholithiasis is uncommon in patients with silicosis. Bronchoesophageal fistula complicated by broncholithiasis is especially rare and only one case has been reported in Korea. Surgical treatment of broncholithiasis should be as conservative as possible to preserve the adequate pulmonary function. Meticulous dissection and division of the fistula with the interposition of viable tissues will prevent recurrence. We report a rare case of bronchoesophageal fistula complicated by broncholithiasis in a patient with silicosis.
