The reconstruction of soft tissue defects with open fracture around the knee joint is limited by its unique location. Free tissue transfer is hindered by the selection of the recipient vessel and problems of microsurgery. The arc of rotation, defect size, and location must be taken into consideration in the use of regional muscle transfer such as gastrocnemius. According to Mathes et al, the flap survival can be enhanced by selective division of the dominant segmental pedicles, only a part of which can normally be transposed safely on its minor segmental pedicle. Neovascularization, vascular proliferation, and dilatation have also been produced by the delay procedure using silicone sheets. The authors have used the delay procedures with wrapping of the gracilis or sartorius muscle which enabled distally-based transposition of these muscles. The method showed satisfactory outcome in resurfacing the wound around the knee joint. The indictions for this procedure were defects of moderate size and those difficult to reach with conventional muscle flaps. The flap could reach the upper one-third of the lower leg. Other merits are relative simplicity and reliability without significant extension of hospital stay. The drawbacks are the two operative procedures necessary and the risk of infection due to silicone sheets.

OBJECTIVE: To compare the clinical outcomes of intrauterine insemination (IUI) according to the catheter used. MATERIALS AND METHOD: From March 1998 to September 1998, total 95 infertile patients were included in this study. Patients were randomly allocated to TomCat group (n = 39) and Mackler group (n = 56) according to the catheter for insemination. The controlled ovarian hyperstimulation (COH) using luteal long protocol of gonadotropin releasing hormone agonist (GnRH-a) was used in all patients. Statistical analysis was performed using Student's t-test, Fisher's exact test, and x2 test as appropriate. Statistical significance was defined as p < 0.05. RESULTS: The total dose and duration of exogeneous gonadotropin required were similar between the two groups. There were also no significant differences in serum estradiol (E2) level, endometrial thickness and texture on the day of hCG administration between the two groups. However, the percentage of uterine souding due to failure of initial approach was significantly higher in TomCat group compared to Mackler group (23.1% vs. 0%, p < 0.01). The percentage of bleeding after IUI in TomCat group seemed to be higher than that in Mackler group (15.4% vs. 3.6%, p = 0.06), although there was no statistically significant difference between the two groups. There was also no significant difference in the clinical pregnancy rate per patient between the two groups. CONCLUSION: These results suggested that using Mackler catheter might be effective for IUI, especially for the patients with cervical factor infertility.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare but potentially fatal drug-induced systemic hypersensitivity response characterized by erythematous eruption, fever, leukocytosis with eosinophilia, and internal organ involvement. Antitubercular agents are potential causative agents for DRESS syndrome but difficult to verify as a culprit drug, since antitubercular agents are coadministered as a combination regimen. A 42-year-old female with endobronchial tuberculosis was diagnosed with DRESS syndrome after 4-week treatment of isoniazid, rifampicin, ethambutol, and pyrazinamide with prednisolone 50 mg. All the antitubercular agents were stopped and replaced with levofloxacin, cycloserine, p-aminosalicylic acid, and kanamycin. However, severe exacerbation of DRESS syndrome compelled the patient to discontinue the administration of the second-line antitubercular agents. Two months later, the patient underwent a patch test for all the antitubercular agents which had been used, and the results showed positivity to isoniazid and cycloserine. We report a rare case of DRESS syndrome that reacted to cycloserine as well as isoniazid. Development of coreactivity to other drugs should be differentiated with a flare-up reaction in the management of DRESS syndrome.

The aim of this study was to determine whether losartan, an angiotensin II (Ang II) type 1 (AT1) receptor could influence the CA release from the isolated perfused model of the rat adrenal medulla. Losartan (5~50 micrometer) perfused into an adrenal vein for 90 min produced dose- and time-dependent inhibition of the CA secretory responses evoked by ACh (5.32 mM), high K+ (56 mM, a direct membrane depolarizer), DMPP (100 micrometer) and McN-A-343 (100 micrometer). Losartan failed to affect basal CA output. Furthermore, in adrenal glands loaded with losartan (15 micrometer) for 90 min, the CA secretory responses evoked by Bay-K-8644 (10 micrometer, an activator of L-type Ca2+ channels), cyclopiazonic acid (10 micrometer, an inhibitor of cytoplasmic Ca2+-ATPase), veratridine (100 micrometer, an activator of Na+ channels), and Ang II (100 nM) were markedly inhibited. However, at high concentrations (150~300 micrometer), losartan rather enhanced the CA secretion evoked by ACh. Collectively, these experimental results suggest that losartan at low concentrations inhibits the CA secretion evoked by cholinergic stimulation (both nicotininc and muscarinic receptors) as well as by membrane depolarization from the rat adrenal medulla, but at high concentration it rather inhibits ACh-evoked CA secretion. It seems that losartan has a dual action, acting as both agonist and antagonist to nicotinic receptors of the rat adrenal medulla, which might be dependent on the concentration. It is also thought that this inhibitory effect of losartan may be mediated by blocking the influx of both Na+ and Ca2+ into the rat adrenomedullary chromaffin cells as well as by inhibiting the Ca2+ release from the cytoplasmic calcium store, which is thought to be relevant to the AT1 receptor blockade, in addition to its enhancement of the CA release.
