Since cardiac pacemaker was first totally implanted by Chardack, Gage and Greatbatch [1966], the electrical circuity of the cardiac pacemaker has been improved, modified, and refined. The problem of transvenous electrodes, however, is still remained; this may be due to electrode displacement, exit and/or entrance block, lead fracture and insulation defects. In permanent cardiac pacing, Irreversible loss of function of the transvenous electrode catheter eventually requires insertion of new lead. Authors now report one case that disclosed easy displacement of electrode tip in early phase of implantation and then two years and five months later, malfunctioning electrode could not be withdrawn from the cardiovascular system because it has become firmly enclosed by fibrous tissue along its course from the vein tract to the right ventricle. Under such circumstances, the electrode catheter tip was left in tricuspid annulus after being sutured at its entrance and burying the loop of lead in generator pocket. New other one electrode was then reimplantation through left external jugular vein.

Central venous catheter (CVC) insertion is commonly used in the operating room and intensive care unit to monitor central venous pressure and secure an intravenous route to deliver medications and nutritional support that cannot be safely infused into peripheral veins. However, CVC insertion may be associated with serious complications such as arterial puncture, hematoma, pneumothorax, hemothorax, catheter infections, and thrombosis. Several methods have been recommended to prevent these complications. Here we report a case of massive hemothorax caused by attempts of CVC insertion into the internal jugular vein and subclavian vein in a patient with multiple trauma. CVC placement should be performed or supervised by an experienced physician to decrease the incidence of CVC-related complications. CVC insertion under ultrasound guidance is recommended.

It has been shown that orexin has an inhibitory effect on gonadotropin secretions in non-ruminant animals. The goal of this study was to determine whether orexin affects LH, and FSH secretions in the camel, as a pseudo-ruminant animal, under different dietary energy content. Sixteen castrated camels were randomly divided into 4 groups. Animals in groups 1 and 2 were fed 100% and animals in groups 3 and 4 were fed 50% energy content in their diet for 20 days. After 20 days, animals in groups 1 and 3 received infusions of 1 $\mu{g}$ orexin and groups 2 and 4 received infusions of 2 $\mu{g}$ orexin into their jugular vein. Blood samples were collected from the jugular vein every 20 minutes from 4 h before the first infusion of orexin until 4 h after the last orexin infusion. Lower dietary energy intake and infusions of 2 $\mu{g}$ but not 1 $\mu{g}$ orexin significantly (p<0.01) decreased the mean plasma concentrations and pulse amplitudes of LH of the animals. Infusion of 1 and 2 $\mu{g}$ orexin did not change the secretions of LH of the animals fed NE. Different energy dietary intake and infusion of 1 and 2 $\mu{g}$ orexin did not change the mean plasma concentrations of FSH of the animals in all groups. Infusions of 1 and 2 $\mu{g}$ orexin significantly (p<0.01) decreased the glucose levels of animals fed LE but not in NE fed animals. Additionally, plasma glucose levels of the LE-fed animals in groups 3 and 4 were significantly (p<0.01) lower than those of the animals in groups 1 and 2 fed NE diet. The results of this experiment indicated that orexin may negatively affect LH and FSH in camels with negative energy balance, but not in those with positive energy balance.

Background: The advance in microsurgical technique has facilitated a proper approach for reconstruction of extensive head and neck defects. For the success of free tissue reconstruction, selection of the recipient vessel is one of the most important factors. However, the vascular anatomy of this region is very complex, and a clear guideline about this subject is still lacking. In this study, we present our 30 years of experiences of free tissue reconstruction for head and neck defects. Methods: In this retrospective study, we analyzed a total of 138 flaps in 127 patients who underwent head and neck reconstruction using free tissue transfer following tumor resection between October 1986 to August 2019. Patients who underwent facial palsy reconstruction were excluded. Medical records including patient's demographics, detailed operation notes, follow-up records, and photographs were collected and analyzed. Results: Among a total of 127 patients, 10 patients underwent a secondary operation due to cancer recurrence. The most commonly used type of flap was radial forearm flap (n=107), followed by the anterolateral thigh flap (n=18) and fibula flap (n=10). With regard to recipient vessels, superior thyroid artery was most commonly used in arterial anastomosis (58.7%), and internal jugular vein (51.3%) was the first choice for venous anastomosis. The flap survival rate was 100%. Four cases of venous thrombosis were resolved with thrombectomy and re-anastomosis. Conclusion: Superior thyroid artery and internal jugular vein were reliable choices as recipient vessels. Proper recipient vessel selection could improve the result of head and neck reconstruction.

The author confirmed the development of the smooth muscle in the oviduct proprius and anterior mesosalpinx in the leghorn, and observed that there was a variation between the action of norepinephrine on albumin-secreting portion of productive oviduct and that of non-productive one, and that $PGE_1$ might play a significant role on the activation of adrenergic ${\alpha}$-receptor in the non-productive oviduct. 1. There were many bundles of smooth muscles with irregular directions, which were identified in the both oviduct proprius and anterior mesosalpinx by Mallory aniline-blue orange G stain. 2. In vitro experiments, the anterior mesosalpinx was always relaxed by norepinephrine. While the albumin-secreting portion of non-productive period of oviduct was relaxed, but that of the productive one contracted by norepinephrine. Both the anterior mesosalpinx and oviduct proprius of chick responsed with relaxation to norepinephrine as shown in the non-productive hen. In vivo experiments, norepinephrine injected through the jugular vein increased the intraoviductal pressure in the productive oviduct, but decreased that in the non-productive one. 3. By treatment with $PGE_1$, in vitro, the relaxation induced not only by norepinephrine, but by periarterial electrical stimulation was converted into contraction, and in the presence of phentolamine, this conversion by $PGE_1$ was not shown. 4. The intra-oviductal pressure of the productive hen treated with indomethacin for 4 days was decreased by norepinephrine, but the increase in pressure by $PGE_1$ or $PGE_{2{\alpha}}$ was supersensitized when these drugs were administered through jugular vein. However, in vivo, the relaxation by norepinephrine was not converted into the stimulation after $PGE_1$ treatment. It might be summarized that the regulation of intra-oviductal pressure was dependent on the summation of the movement of both oviduct and mesosalpinx and intramurally produced prostaglandins contributes to the inherent tone of the prcductive oviduct by activating adrenergic ${\alpha}$-receptor.
