Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.

Malignant hyperthermia is a well-recognized syndrome of uncertain etiology. The confusing facts are: the variety and different nature of the triggering agents, the variation in time of onset of rigidity and fever coupled with a variation in response to succinylcholine, the lack of family history in some patients, and its occurence in some who have had previously normal general anesthetics. A case is a 23 year old relatively healthy male patient in whom subtotal gastrectomy was performed under N2O-O2-ether and gallamine anesthesia with induction after pentothal sodium and succinylcholine. This was complicated by an abrupt, high rise in body temperature, muscle rigidity, flushing with peripheral cyanosis, disseminated intravascular coagulation and hyperpnea 40 minutes after induction. He died 3 hours after cessation of anesthesia without effective response to any active antipyretic therapy. The etiologic factors, incidence, clinical feature, prevention, treatment and prognosis of malignant hyperthermia are discussed.

BACKGROUND: Pneumoperitoneum for a gynecologic laparoscopic surgery induces hemodynamic changes. We evaluated the effects of nicardipine on induction, maintenance, and recovery. METHODS: Thirty patients scheduled for gynecologic laparoscopic surgery were randomly allocated to two groups: control group (placebo group, n = 15), group N (nicardipine group, 10 microgram/kg followed by 0.5-2.0 microgram/kg/min). The systolic arterial pressure, mean arterial pressure, and heart rate were measured at preinduction, induction, intubation and 5, 10, 15, 20 min after insufflation. Loss of consciousness, induction dose, effective site concentration, propofol maintenance dose (the maintenance dose of propofol from intubation to end of anesthesia, PMD) were also measured. Propofol was titrated to maintain a bispectal index value of 40-60. RESULTS: There was a significant difference in PMD between two groups. The PMD of group N was significantaly less than group C. Nicardipine adminstration attenuated increase in the blood pressure, but did not affect on heart rates during CO2 insufflation. CONCLUSIONS: Co-administration of nicardipine was effective in attenuating the hemodynamic changes after pneumoperitoneum during gynecologic laparoscopic surgery, without changes of induction and recovery.

BACKGROUND: A "difficult airway" can be simulated with an extrication collar, which restricts cervical motion and mouth opening. The purpose of this study is to compare the efficacy of the GlideScope and the McGrath in difficult airway simulation. METHODS: Patients were randomized using computer-generated numbers and were placed into the GlideScope group or the McGrath group. The total intubation time was defined as the time measured from when the anesthesiologist picks up the device to the time at which three successive end-tidal CO2 values are acquired after intubation. RESULTS: There was no significant difference in total intubation time between the two groups (73.0 ± 25.3 sec vs. 72.3 ± 20.9 sec, P = 0.92). The success rates of the first intubation attempt did not differ between the two groups (82.8% vs. 83.3%, P = 0.95). CONCLUSIONS: Our results suggest that there are no significant differences in the intubations with GlideScope and McGrath using vascular forceps and tube exchangers in difficult intubation scenarios.

BACKGROUND: The Rhodes index of nausea, vomiting and retching (RINVR) is a reliable and valid instrument to assess PONV. The purpose of this study was to investigate the incidence of PONV in high risk group with using RINVR. METHODS: Patients scheduled for elective surgery under general anesthesia were classified in three groups (group I:two risk factors, group II:three risk factors, group III:four risk factors) by using a simplified risk score.We investigated the incidences of PONV in each group. RESULTS: The incidence of PONV was 12.8% in group I, 25% in group II, and 33.1% in group III, which showed a significant difference between group I and group II, between group I and group III.The incidence of PONV, which was over moderate was significantly increased in group III. CONCLUSIONS: For patients with three or four risk factors a multimodal antiemetic strategy should be considered.

BACKGROUND: Several publications have reported the successful, safe use of Laryngeal Mask Airway (LMA)-Classic devices in patients undergoing laparoscopic surgery. However, there have been no studies that have examined the application of volume-controlled ventilation (VCV) or pressure-controlled ventilation (PCV) using a LMA during gynecological laparoscopy. The aim of this study is to compare how the VCV and PCV modes and using a LMA affect the pulmonary mechanics, the gas exchange and the cardiovascular responses in patients who are undergoing gynecological laparoscopy. METHODS: Sixty female patients were randomly allocated to one of two groups, (the VCV or PCV groups). In the VCV group, baseline ventilation of the lung was performed with volume-controlled ventilation and a tidal volume of 10 ml/kg ideal body weight (IBW). In the PCV group, baseline ventilation of the lung using pressure-controlled ventilation was initiated with a peak airway pressure that provided a tidal volume of 10 ml/kg IBW and an upper limit of 35 cmH2O. The end-tidal CO2, the peak airway pressures (Ppeak), the compliance, the airway resistance and the arterial oxygen saturation were recorded at T1: 5 minutes after insertion of the laryngeal airway, and at T2 and T3: 5 and 15 minutes, respectively, after CO2 insufflation. RESULTS: The Ppeak at 5 minutes and 15 minutes after CO2 insufflation were significantly increased compared to the baseline values in both groups. Also, at 5 minutes and 15 minutes after CO2 insufflation, there were significant differences of the Ppeak between the two groups. The compliance decreased in both groups after creating the pneumopertoneim (P < 0.05). CONCLUSIONS: Our results demonstrate that PCV may be an effective method of ventilation during gynecological laparoscopy, and it ensures oxygenation while minimizing the increases of the peak airway pressure after CO2 insufflation.
