OBJECTIVE: This study was performed to evaluate the feasibility, safety, and tolerance of early postoperative oral feeding in gynecologic patients who have underwent intra-abdominal surgery. Thus, we investigated the clinical efficacy of early postoperative oral feeding in gynecologic patients, prospectively. METHODS: From September 1998 to March 1999, we studied 80 gynecologic patients undergoing laparotomy at Department of Obstetrics and Gynecology, Yonsei University College of Medicine, prospectively. After surgery, the patients were grouped into two arms; the first early oral feeding group began a clear liquid diet on the first postoperative day and advanced to regular diet as tolerated. the second control group received nothing by mouth until return of bowel function. RESULTS: Although more patients in the study group developed nausea, the incidence of vomiting and abdominal distension were comparable in both groups. Time to development of bowel sound and flatus were significantly shorter in study group. Postoperative complications including pneumonia, atelectasis, wound complications, and febrile morbidity occurred insignificantly in both group. Postoperative changes in hematologic indices and electrolytes were comparable in both group. CONCLUSION: Early postoperative oral feeding in gynecologic patients undergoing intra-abdominal surgery is safe, well tolerated. We believe that re-evaluation of postoperative surgical care may increase our knowledge and better serve our patients.

Granulomatous mycosis fungoides is an extremely rare and unusual histologic variant of mycosis fungoides. This form is clinically characterized by spontaneous resolution of ulcerated nodular lesions into poikiloderma. Histologically, a strong granulomatous component can obscure the underlying cutaneous lymphoma, which is frequently mistaken for non-neoplastic dermatitides or cutaneous sarcoidosis. We report a case of granulomatous mycosis fungoides occurring on the left cheek of 34-year-old man confirmed histologically with an aid of immunohistochemistry and clinical course (immediate response to PROMACE-CYTOBAM chemotherapy), with emphasis on differential diagnosis, along with a review of literature. This is the first documented report in the Korean literature.

A newborn infant, who was low-birth weight(1,780gm), showed severe degree of jaundice on second day of life and skin color became dark greenish-yellow and moderate hepatosplenomegaly was noted on physical examination. Results of liver function test & radioimmuniassay for hepatitis B antigen of both infant and mother suggested that neonatal hepatitis B seemed to occure transplacentally during pregnancy from infected mother. Pancytopenia was followed, but we could not confirm aplastic anemia due to lack of bone marrow specimen. As mentioned above, we experienced a case of vertically transmitted neonatal hepatitis B with pancytopenia. We present a brief review of related literatures.

Purpose: This study aimed to identify the relationships among attitudes towards death, perceptions of hospice care, and hospice care needs as perceived by family members of patients in the intensive care unit (ICU). Methods: This study used a descriptive correlational method. A structured questionnaire was used to collect data from 114 participating families in the ICU at Dong-A University Hospital, from October 10 to November 1, 2019. The data were analyzed in terms of frequency, percentage, and mean and standard deviation. The t-test, one-way analysis of variance, and Pearson correlation coefficients were also conducted. Results: Perceptions of hospice care showed significant differences according to age (F=3.06, P=0.031) and marital status (t=3.55, P=0.001). However, no significant differences in attitudes towards death or hospice care needs were found. A significant positive correlation was found between perceptions of hospice care and hospice care needs (r=0.49, P＜0.001). Conclusion In order for families to recognize the need for hospice care and to receive high-quality palliative care at the appropriate time, it is necessary to increase public awareness of hospice care through various educational and awareness-raising efforts, thereby providing opportunities for families of terminally ill patients to request hospice care.

The purpose of this study was undertaken to test if alteration of calcium flux across the sarcolemma or sarcoplasmic reticulum change subsequent relaxation of rat aorta in tissue model of ischemia. Thoracic aorta ring segments(2-3mm wide) were studied with solution that mimicked real ischemia condition(hypoxia, acidosis, elevated lactate levels and zero sub strate). During ischemic condition, the effect of treatments thought to decrease cytosolic cal cium were tested. Half time(t(1/2)) and degree of stabilized relaxation were 2.4+/-0.9 minutes and 17.6+/-12.1%(NE 10-7 M precontraction as 100%) for verapamil(10-6 M), 3.3+/-0.7 min- utes, 22.2+/-3.9% for low Ca2+(0.75mM) in ischemic solution. Interventions aimed to elevat- ing cytosolic calcium were also tested. 3.8+/-0.9 minutes and 68.6+/-8.1% for high (10.0 mM) Ca2+ in ischemic solution, 3.7+/-0.7 minutes, 72.8+/-3.9/. for ryanodine(3X10-9 M). 3.8+/-0.5 minutes, 53.4+/-2.6% for isoproterenol. Without any treatment or agents during ischemia, hlaf time and degree of relaxation were 4.0+/-1.7 minutes, 74.6+/-13.2%, enothelium and time independent. These data support that treatment or agent thought to reduce influx of cytosolic calcium levels exaggerated the severity of relaxation. The mechanism of relaxation in ischsmia is not completely clear, but it is suggested that a reduction of calcium influx may involved and directly related.

During ventilatory support via tracheostomy tube, the desire to communicate verbally is common and loss of speech may result in great fear, frustration in the long-term tracheostomized patients. Several methods of communication have been developed in an effort to alleviate this discomfort and anxiety. This case presents our experience of using speaking tracheostomy tube which allowed the patient to talk while on a vetilatior. A small catheter(inner diameter 1mm) which provided an opening with gases flowed upward through the vocal cords was adapted to the standard tracheostomy tube and connected to an oxygen flowmeter(3~5L/min.) with a Y shaped connector for intermittent control. When the open side of the Y connector was occluded, gases flowed into the subglottic area, allowing for vocalization. Though experience with this method was somewhat disappointing than normal sound, their use in long-term and chronic ventilating patients was proved satisfactory.

PURPOSE: In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallgladders. MATERIALS AND METHODS: A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave Iothotriptor. The gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II( 4 rabbits), and group III(3 tabits), respectively. The rabbits were sacrified 6--12 hours later. RESULTS: The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologeic changes with dilatation and structural alterations of endoplasmic reticulums were more profund at value of 100. CONCLUSION: Early histologic changes induced by shock waves are dose dependent and the findings of cellular damage caused by ESWL might be explained as above.

BACKGROUND: The potent bronchodilatory effects of ketamine on airway smooth muscle tone are important in the management of patients with asthma, but its mode of action is unclear. In the present study we evaluated that effects on isolated guinea pig tracheal smooth muscle. METHODS: Changes of isometric contraction of strip were measured. (1) Serial stimulation with acetylcholine(ACh) in Krebs solution or with A23187, nifedipine, ketamine were evaluated. After that, ACh stimulation was induced in Ca2+ free solution. (2) In Ca2+ free solution, ACh contraction was obtained(L1) and emptied by repetitive ACh stimulation. Internal stores were refilled by Ca2+ with ACh stimulation. During the incubation period, A23187, nifedipine, ketamine, cyclopiazonic acid + ketamine was added and tested for their ability to inhibit refilling. Refilling was evaluated by ACh produced contraction (L2) with ratio (L2/L1). (3) Effects of ketamine on the contraction induced by caffeine were also checked. RESULTS: Ketamine inhibited amplitude dose-dependently by successive application of ACh in modified Krebs solution and Ca2+ free solution. Ca2+ influx through voltage gated channels were inhibited with nifedipine but not with A23187. ACh sensitive internal store were different when A23187, nifedipine and ketamine were applied in Ca2+ free solution. Refilling of internal store were potentiated by A23187, but decreased by nifedipine and ketamine. Caffeine produced contractions in the presence of ketamine were not significantly different from control. CONCLUSION: We concluded that the inhibitory effects of ketamine in guinea pig trachea were by acting through voltage and receptor gated channels in dose-depedent manner and these effects may be interferences of intracellular second messengers system.

The mechanism of vasodilation induced by fentanyl was investigated using isolated rat thoracic aortic rings. Rings were contracted with norepinephrine(10(-7) M, NE) and potassium chloride(40 mM, KC1) with and without endothelium Fentanyl (10(-9)-10(-5) M) produced dose-dependent relaxation and had no significant effect from endothelium(intact and denuded rings, test with 3X10(-4) M LNAME, N-nitro-L-arginine methyl ester). Pretreatment of indomethacin(2.5X10(-3) M, inhibitor of cyclooxygenase) failed to influence of cumulative dose-response curves. RD(50)(50% relaxation dose) and KC1/NE ratio as potency difference of fentanyl, verapamil(10(-8)-10(-5) M, Ca2+ channel blocker), nitroglycerin(10(-10)-10(-5) M, activator of guanylate cyclase) were not similar. Fentanyl and control(distilled water) were not demonstrated any different contraction produced by incremental addition of Ca2+ to aortic rings exposed to Ca2+ free, K+ -depolarized(100 mM KCl) solution(extracellular Ca2+ influx). But fentanyl had effect on intracellular Ca2+ release elicited by caffeine(20 mM) and NE(10(-7) M) indicated by dose-dependent inhibition of contraction in Ca2+ free solution. We conclude that, in rat aorta, fentanyl-induced relaxation is endothelium-independent but mediated by inhibition of alpha-adrenoceptors operated intracellular Ca2+ release (inhibition of contraction by NE) and caffeine-induced Ca2+ release from store.
