Bethanechol, a cholinergic agonist, has been recommended for the management of peripheral anticholinergic side effects during the treatment of antipsychotic medications. But there have been few studies which have evaluated the drug interactions of antipsychotics and bethanechol, even the treatment effects of bethanechol on anticholinergic side effects. So the authors have evaluated whether psychopathology and plasma haloperidol and reduced haloperidol concentrations are significantly changed or not when bethanechol was administrated with maintained doses of haloperidol and other coadministrated drugs(such a benztropine). Also we have evaluated the abating effects of bethanechol on anticholinergic side effects during the treatment with haloperidol. Fifteen schizophrenics with higher than 5 of total score of anticholinergic side effects of 'Rating scale for side effect' were assigned to two groups, and bethanechol 30mg/day and 60mg/day were applied on each group for 4 weeks. The daily haloperidol dosages were fixed before 2 weeks of study. We assessed anticholinergic side effects by 'Rating scale for side effect' and psychopathology by BPRS, and plasma haloperidol and reduced haloperidol concentrations by HPLC at baseline, 2nd week and 4th week. The results were as followed. 1) There was no significant change of plasma haloperidol and reduced haloperidol concentration. 2) At baseline, the dosage of haloperidol showed significant correlation with the total score of anticholinergic side effect, but not at 2nd week and 4th week. 3) In 60mg/day group, dry mouth and the total score of anticholinergic side effects were significantly improved, but not in 30mg/day group. 4) There was no significant change of BPRS except withdrawal at 2nd week. These results suggest that coadministration of bethanechol influenced neither on psychopathology nor on plasma haloperidol and reduced haloperidol concentrations and that improved dry mouth and total score of anticholinergic side effects at 60mg/day.

The effects of intraventricular alpha2-adrenoceptor agonist and antagonist, clonidine and rauwolscine, on changes of blood pressure induced by the rise of intracranial pressure were investigated in urethane-anesthetized rabbits. 2) The rise of ICP, induced by the infusion of saline into a balloon placed in the epidural space, was comparatively slow in the beginning of the infusion but became sharp as the infusion proceeded. Corresponding with the gradual increase of ICP, there was a slight decrease in BP. An abrupt rise of BP was observed when ICP showed a sharp increase. 3) Intraventricular rauwolscine 5(microgram) by itself did not affect BP. In these rauwolscine-treated rabbits the increase of both ICP and BP by the infusion was similar to that of the control animals. 4) The pretreatment with rauwolscine 50(microgram) did hardly affect BP, but this made the increase of ICP and BP by the infusion different from that of the control animals. The slight hypotensive response in the beginning of the infusion did not appear and the pressor response to the raised ICP was markedly facilitated. The volume of saline inused into the infusing balloon to cause the same increase of ICP as in the control animals was much smaller than in the control ones, and the magnitude of the maximal increase of BP was much greater. 5) The pretreatment with 500 microgram of intraventricular rauwolscine produced an increase of BP. In these animals the increase of both ICP and BP by the infusion seemed to be slightly facilitated than in the control animals. 6) Intraventricular clonidine 30(microgram) markedly decreased BP. In these clonidine-treated animals the slight hypotensive response in the beginning was more distinct than in the control animals, and the pressor response was hardly seen. 7) The hypotensive response to intraventricular clonidine 30(microgram) was weakened in the animals pretreated with intraventricular rauwolscine 500(microgram). In these animals the increase of both ICP and BP by the infusion appeared as in the control animals. 8) The above results suggest that the pressor response to the raised ICP in rabbits was inhibited under the condition of stimulation of central alpha2-adrenoceptors and facilitated under the condition of blockade of the receptors. It seems that the rise of blood pressure takes place when the activity of alpha2-adrenoceptors is impared by the increased pressure of the balloon placed in the epidural space.

BACKGROUND: V. vulnificus infection is found between May and October when the man who has hepatic disorder or immunity disorder eats raw shellfish and it causes the systemic symptoms such as sudden fever, chilling, shock and stupor and local skin lesions like blob and necrosis. This disease has 46~61% of fatality rate in spite of intensive treatment. This study conducts the examination of history, epidemic study, ingesting raw fish and bacteriologic investigation in the patients with similar clinical symptoms to the above and examines the diagnostic correlations. METHOD: It is conducted with 31 cases who admitted at emergency medical center of Chosun University Hospital from May of 1995 to September of 1998 and are suspected to have V. vulnificus infection. It analyze bacteriologic examination, the survey of residence, eating raw shellfish, hepatic disorder, alcohol drinking habits and skin lesion. RESULTS: 1)the rate of male and female is 15.5:1 and in the age, 18 cases are in fifties, seven ale in fifties and six are over sixties. 2) Clinically, V. vulnificus is detected in 20 of 31 cases which is suspected to have V. vulnificus i18c1ion and it is not detected in 5 cases. Other bacteria are detected in 6 cases and they include staphylococcus aureus, pseudomonas species, beta hemotytic streptococcus and E-coil. 3) In local distribution, Kohung has 10 cases, Shinan and Mokpo have six, Haenam and Kangjin have aye, Yongkwang and Muan have five, Naju and Yongam have five and Kwangju has one. 4) Eating fishes and raw shellfishes is found in 31 cases. In the kind of shellfishes, eating raw clam is 10 cases, raw thin-shelled surf calm is 8 cases, raw oyster is 5 cases and sliced raw fish is 4 cases and pickled sea floods ate 4 cases. 5) The cases with hepatic disorder are 23 and 15 Gases with heavy alcohol dunking Carrier are included. The cases with Diabetic Mellitus are four and those with pulmonary tuberculosis are two. Two cases have not basal diseases. 6) On the opinion of skin lesion, 20 cases show vesicular necrosis, 7 cases have dendriform erythema, 3 cases have papule and one case doesn't show clear skin lesion. CONCLUSION: When V. vulnificus infection is detected, it is fatal and those who have hepatic disorder or heavy alcohol drinking habit must avoid eating fishes and shellfishes raw in summer. It is important to have emergency treatment for the patient whose V. vulnificus infection is suspected. It is considered that the administration of initial antibiotics is effective by generalizing the clinical symptom, epidemic opinion and patient history even before the results of bacteriologic confirmed.

Background:
The purpose of this study was to evaluate the association of body mass index (BMI) and waist circumference (WC) with the risk of Achilles tendinopathy (AT) or Achilles tendon rupture (ATR), using data from a nationwide population-based cohort.We hypothesized that higher BMI and WC would be independently associated with the increased risk of AT or ATR. In addition, a higher WC may potentiate the association between BMI and the risk of Achilles tendon problems.
Methods:
We used the National Health Insurance database that covers the entire South Korean population to follow up subjects who participated in the National Health Screening Program (NHSP) from January 2009 to December 2010. The NHSP data include subjects’ BMI, WC, blood test results, blood pressure, and information about lifestyle. Among the subjects, those who were newly diagnosed as having AT or ATR before December 31, 2017, were selected. To examine the association of the variables with the risk of AT or ATR and determine whether the effect of higher BMI varied according to WC, multivariate Cox proportional hazards regression was used.
Results:
Among a total of 16,830,532 subjects, 125,814 and 31,424 developed AT and ATR, respectively. A higher BMI showed a greater association with the increased risk of ATR than AT (adjusted hazard ratio [HR], 3.49 vs. 1.96). A higher WC was associated with the increased risk of AT (adjusted HR, 1.22), but not ATR. In a separate analysis, the association between BMI and the risk of AT was higher when subjects had higher WC as compared to those with lower WC, being most significant in individuals with both higher BMI and higher WC.
Conclusions
Higher BMI was more associated with the increased risk of ATR than AT. Moreover, a high central fat distribution played an independent and potentiating role in the development of AT. This implies the greater importance of a high central fat distribution contributing to the development of AT in obese people.

The efficacy of P2Y12 reaction unit (PRU) of VerifyNow still remains as a controversial issue in neurointervention. So we investigated the usefulness of PRU of VerifyNow to predict the peri-procedural thromboembolic events (TE) and hemorrhagic events (HE). And we evaluated the safety of modified dual antiplatelet therapy (DAPT) or triple antiplatelet therapy (TAPT) for clopidogrel hyporesponders. We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science and Scopus on August 19 2018. Data was collected the 1) incidence of TE between clopidogrel responder and clopidogrel hypo-responder, 2) incidence of HE between clopidogrel hyper-responder and clopidogrel responder and hypo-responder, and 3) incidence of TE and HE between modified DAPT or TAPT and standard DAPT in clopidogrel hypo-responder. High cut-off value of PRU was defined as PRU >40% or <220. Fifteen studies were enrolled. Clopidogrel responder showed lower incidence of TE than hypo-responder (risk ratio [RR], 0.32; 95% confidence interval [CI], 0.17-0.61; p<0.001). With the high cut-off value of PRU, clopidogrel responder showed more lower incidence of TE than hypo-responder (RR, 0.11; 95% CI, 0.02-0.45; p=0.002). The incidence of periprocedural HE have higher on clopidogrel hyper-responder than clopidogrel responder and hypo-responder (RR, 4.26; 95% CI, 1.10-16.44; p=0.04; I2=66%). The incidence of periprocedural TE after changing regimen of DAPT for clopidogrel hypo-responder have a tendency to reduce, but there was no significant difference between modified DAPT or TAPT group and standard DAPT group (p>0.05). The incidence of periprocedural HE after changing regimen of DAPT for clopidogrel hypo-responder was no significant difference between modified DAPT or TAPT group and standard DAPT group (p>0.05). PRU is a useful tool as a predictor of peri-procedural TE or HE on neurointervention. PRU has a threshold effect of cut-off value to predict the peri-procedural TE. Modified DAPT or TAPT to prevent TE in clopidogrel hypo-responders could not reduce the incidence of TE. We should investigate the further research about modification of regiment on neurointervention.

Cerebral cysticercosis is relatively common disease in Korea. But cysts in the ventricular system are rare form. In the ventricular system, they occur most frequently in the 4th ventricle, more rarely in the lateral and 3rd ventricle. We have recently experienced a case of cerebral cysticercosis which involved the 3rd ventricle. A sixty-year old man was admitted because of generalized seizure attack followed by drowsy mentation. On admission, there were no specific localizing and lateralizing neurological abnormalities except bilateral, mild degree optic papilledema. Brain CT scan after intraventricular metrizamide administration disclose a cystic mass in the third ventricle. And the serum ELISA test was positive(patient's titer : 0.31, normal : below 0.18). Anterior transcallosal approach was performed and cystic mass was removed from the third ventricle. Pathological diagnosis of the specimen was cysticercosis. Following surgery, the patient's symptom cleared up and papilledema disappeared gradually.

Purpose:
Managing recurrent inguinal hernias is complex, and choosing the right surgical approach (laparoscopic vs. open) is vital for patient outcomes. This study compared the outcomes of using the same vs. different surgical approaches for initial and subsequent hernia repairs.
Methods:
We retrospectively analyzed patients who underwent recurrent inguinal hernia repair at Seoul National University Bundang Hospital between January 2014 and May 2023. Patients were divided into the “concordant” and “discordant” groups, comprising patients who underwent same and different approaches in both surgeries, respectively. Preoperative baseline characteristics, index surgery data, postoperative outcomes, and recurrence rates were analyzed and compared.
Results:
In total, 131 patients were enrolled; the concordant and discordant groups comprised 31 (open, n = 19; laparoscopic, n = 12) and 100 patients (open to laparoscopic, n = 68; laparoscopic to open, n = 32), respectively. No significant differences were observed in the mean operation time (50.5 ± 21.7 minutes vs. 50.2 ± 20.0 minutes, P = 0.979), complication rates (6.5% vs. 14.0%, P = 0.356), or 36-month cumulative recurrence rates (9.8% vs. 9.8%; P = 0.865). The mean postoperative hospital stay was significantly shorter in the discordant than in the concordant group (1.8 ± 0.7 vs. 1.4 ± 0.6, P = 0.003).
Conclusion
Most recurrent inguinal hernia repairs were performed using the discordant surgical approach. Overall, concordance in the surgical approach did not significantly affect postoperative outcomes. Therefore, the selection of the surgical approach based on the patient’s condition and surgeon’s preference may be advisable.
