Penetration of the Duodenum by an Ingested Needle with Migration to the Pancreas: Report of a Case

A case of a penetration of the duodenum by a needle with migration to the pancreas in a 50-year-old man is reported herein. The patient was referred to us with a chief complaint of diarrhea. An abdominal plain roentgenogram showed a needle in the upper abdominal area. An abdominal computed tomography scan and contrast X-ray revealed the foreign body to be located outside of the duodenum and in the head of the pancreas. An emergency operation was therefore performed on the first day and the needle in the head of the pancreas was thus extirpated safely. A perforation of the gastrointestinal tract by an ingested foreign body is difficult to accurately and quickly diagnose when no peritonitis or abscess formation is observed. Therefore, the use of contrast X-ray is considered to be useful in the diagnosis of such a perforation. Received: January 24, 2000 / Accepted: July 25, 2000     

Atrial Fibrillation After Ischemic Stroke Detected by Chest Strap-Style 7-Day Holter Monitoring and the Risk Predictors: EDUCATE-ESUS

Aim: This study aimed to investigate the diagnostic yield of 7-day Holter monitoring for detecting covert atrial fibrillation (AF) in patients with recent embolic stroke of undetermined source (ESUS) and to identify the pre-entry screening biomarkers that had significant associations with later detection of AF (clinicaltrials.gov. {"type":"clinical-trial","attrs":{"text":"NCT02801708","term_id":"NCT02801708"}}NCT02801708). Methods: A total of 206 patients who have recent ESUS without previously documented AF underwent Holter electrocardiography using a chest strap-style monitor. External validation of biomarkers predictive of AF was performed using 83 patients with ESUS who were implanted with insertable cardiac monitors. Results: The 7-day Holter monitoring started at a median of 13 days after the onset of stroke. AF was detected in 14 patients, and three of these showed a single AF episode lasting ＜2 min. The median time delay to the first documented AF was 50 h. Each of serum brain natriuretic peptide ≥ 66.0 pg/mL (adjusted odds ratio 5.23), atrial premature contractions (APCs) ≥ 345 beats (3.80), and APC short runs ≥ 13 (5.74) on 24-h Holter prior to the 7-day Holter showed a significant association with detection of AF, independent of age and physiological findings in this derivation cohort, and all of these showed a significant association in the validation cohort (adjusted odds ratio 6.59, 7.87, and 6.16, respectively). Conclusions: In recent ESUS patients, the detection rate of AF using the 7-day Holter monitoring was 6.8% (95% CI 4.1%–11.1%). Brain natriuretic peptide, APC count, and APC short runs in the standard clinical workup seemed to be predictors of covert AF.     

Change in the post-discharge destinations from a senile dementia therapy ward in Japan: the second report

Background: The new long‐term care insurance (LTCI) system, known as Kaigo‐Hoken, was implemented in April 2000. We previously reported a change in the type of destination after discharge from a senile dementia therapy ward (named the Midori ward) following implementation of the LTCI system at Fukuoka Prefectural Onga Hospital during the period from 1 April 1999 to 31 March 2001 in Psychogeriatrics (2003; 3 : 104–108). We subsequently investigated the type of destination after discharge from the Midori ward at Fukuoka Prefectural Onga Hospital during the period from 1 April 2001 to 31 March 2002. Methods: We used data from a total of 320 discharged inpatients with dementia who fulfilled the criteria according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM‐IV) for dementia of the Alzheimer's type, vascular dementia and other types of dementia. We compared the period from 1 April 1999 to 31 March 2000 before the LTCI implementation and the periods from 1 April 2000 to 31 March 2001 and 1 April 2001 to 31 March 2002 after the LTCI implementation. The type of destination after discharge and the place of origin of the inpatients before admission were classified into one of the following groups: (i) nursing home or geriatric care facility group; (ii) hospitalization group; (iii) home group; and (iv) death group. Results: No significant change was evident when the subjects’ post‐discharge destinations were compared or when the subjects’ pre‐admission residences and post‐discharge destinations were compared. These results were similar to our previous report which appeared in Psychogeriatrics (2003; 3 : 104–108). Conclusion: While the LTCI system has become more widely used, it is still necessary to analyze each case and provide the care that encourages people with dementia in senile dementia therapy wards to return to their homes under the LTCI system.     

Drug-induced liver injury caused by an herbal medicine, bofu-tsu-sho-san

A 37-year-old woman was admitted to a hospital with jaundice. Within a couple of weeks, her liver function improved with only symptomatic therapy. About 30 to 60 days before admission, she had taken a herbal medicine, bofu-tsu-sho-san. A diagnosis of drug-induced liver injury was made according to the diagnostic scale proposed at the Digestive Disease Week-Japan 2004. A drug-lymphocyte stimulation test for each ingredient of bofu-tsu-sho-san; the results were positive for Cnidii Rhizoma, Angelicae Radix and Menthae Herba. The liver biopsy specimen revealed features of acute hepatitis. Physicians should be aware that bofu-tsu-sho-san can cause liver injury, as this drug is commonly used as an over-the-counter medicine.     

An alternative method for vermilion reconstruction after resection of hemangiomas of the lip.

PURPOSE: We describe a method for symmetrical vermilion reconstruction after resection of hemangiomas of the lip. PATIENTS AND METHODS: Four patients underwent vermilion reconstruction after resection of large cavernous hemangiomas of the lip. This reconstruction technique employed 3 basic components: 1 ) labial mucosal advancement flap, 2 ) orbicularis oris muscle flap, if necessary, and 3 ) free mucosal graft. RESULTS: All patients successfully underwent the planned procedures without significant complications. Symmetrical profiles of vermilion of the lip were achieved in all cases, even when an extended excision had been performed. CONCLUSIONS: We have found that the combination of labial mucosal advancement flaps, with or without muscular flaps, and free mucosal grafts provides excellent esthetic outcomes with a low complication rate. This method should be incorporated into the surgical techniques for symmetrical reconstruction after resection of hemangiomas of the lip.     

Post-flood--infectious diseases in Mozambique

INTRODUCTION: The types of medical care required during a disaster are determined by variables such as the cycle and nature of the disaster. Following a flood, there exists the potential for transmission of water-borne diseases and for increased levels of endemic illnesses such as vector-borne diseases. Therefore, consideration of the situation of infectious diseases must be addressed when providing relief. The Japan Disaster Relief (JDR) Medical Team was sent to Mozambique where a flood disaster occurred during January to March 2000. The team operated in the Hokwe area of the State of Gaza, in the mid-south of Mozambique where damage was the greatest. METHODS: An epidemiological study was conducted. Information was collected from medical records by abstracting data at local medical facilities, interviewing in habitants and evacuees, and conducting analyses of water. RESULTS: A total of 2,611 patients received medical care during the nine days. Infectious diseases were detected in 85% of all of patients, predominantly malaria, respiratory infectious diseases, and diarrhea. There was no outbreak of cholera or dysentery. Self-reports of the level of health decreased among the flood victims after the event. The incidence of malaria increased by four to five times over non-disaster periods, and the quality of drinking water deteriorated after the event. CONCLUSIONS: Both the number of patients and the incidence of endemic infectious diseases, such as malaria and diarrhea, increased following the flood. Also, there was a heightening of risk factors for infectious diseases such as an increase in population, deterioration of physical strength due to the shortage of food and the temporary living conditions for safety purposes, and turbid degeneration of drinking water. These findings support the hypotheses that there exists the potential for the increased transmission of water borne diseases and that there occurs increased levels of endemic illnesses during the post-flood period.     

Pulmonary pressure-flow relation as a determinant factor of exercise capacity and symptoms in patients with regurgitant valvular heart disease

BACKGROUND: Exertional dyspnea is a frequent limiting symptom in patients with chronic heart failure. Furthermore, dyspnea and a plateau in VO(2) (oxygen consumption) at peak exercise often co-exist in chronic heart failure, especially in patients with severe regurgitant valvular heart disease (RVHD), their relevance to hemodynamics and subjective symptoms during exercise have not been fully understood. OBJECTIVES: The purpose of this study was to examine the determinant factor of exercise capacity in patients with RVHD. METHODS: We performed a symptom-limited cardiopulmonary exercise test using a sitting cycle ergometer with right heart catheterization in 20 patients with severe RVHD. VO(2) and hemodynamics were measured at rest and during exercise, and symptomatic end-point at peak exercise was evaluated by using Borg's score. RESULTS: Of the 20 patients, 11 attained a plateau in VO(2) at peak exercise (Group 1). At peak exercise, pulmonary arterial pressure (PAP) was higher, and cardiac output (CO) and VO(2) were lower in Group 1 than in patients without a plateau in VO(2) (Group 2) (mean PAP: 60+/-10 vs. 48+/-9 mm Hg, P=0.05; CO: 8.3+/-2.6 vs. 11.2+/-2.6 l/min, P=0.01; VO(2): 1059+/-259 vs. 1359+/-328 ml/min, P=0.01). In Group 1, 6 patients complaining of dyspnea rather than leg fatigue at peak exercise had lower CO (7.1+/-1.8 vs. 9.7+/-3.0 l/min, P=0.05) and higher slope of mean PAP-CO relation (P-Q slope) (10.6+/-3.6 vs. 5.4+/-1.7, P=0.01), compared with the other 5 patients with leg fatigue. CONCLUSIONS: Development of pulmonary hypertension during exercise is the important limiting factor for exercise capacity in patients with RVHD. The limitation of increase in CO concomitant with pulmonary hypertension could be an important factor in the appearance of dyspnea.     

Capsaicin-Induced Glutamate Release Is Implicated in Nociceptive Processing Through Activation of Ionotropic Glutamate Receptors and Group I Metabotropic Glutamate Receptor in Primary Afferent Fibers

Glutamate (Glu) is the major excitatory neurotransmitter in the central nervous system. The role of peripheral Glu and Glu receptors (GluRs) in nociceptive transmission is, however, still unclear. In the present study, we examined Glu levels released in the subcutaneous perfusate of the rat hind instep using a microdialysis catheter and the thermal withdrawal latency using the Plantar Test following injection of drugs associated with GluRs with/without capsaicin into the hindpaw. The injection of capsaicin into the rat hind instep caused an increase of Glu level in the s.c. perfusate. Capsaicin also significantly decreased withdrawal latency to irradiation. These effects of capsaicin were inhibited by pretreatment with capsazepine, a transient receptor potential vanilloid receptor 1 (TRPV1) competitive antagonist. Capsaicin-induced Glu release was also suppressed by combination with each antagonist of ionotropic GluRs (iGluRs: NMDA/AMPA receptors) and group I metabotropic GluR (mGluR), but not group II and group III mGluRs. Furthermore, these GluRs antagonists showed remarkable inhibition against capsaicin-induced thermal hyperalgesia. These results suggest that Glu is released from the peripheral endings of small-diameter afferent fibers by noxious stimulation and then activates peripheral iGluRs and group I mGluR in development and/or maintenance of nociception. Furthermore, the activation of peripheral NMDA/AMPA receptors and group I mGluR may be important in mechanisms whereby capsaicin evokes nociceptive responses.     

Which Has Superior Acid-Suppressive Effect, 10 Mg Omeprazole Once Daily or 20 Mg Famotidine Twice Daily? Effects of Single or Repeated Administration in Japanese <Emphasis Type="Italic">Helicobacter Pylori</Emphasis>-Negative CYP2C19 Extensive Metabolizers

Low-dose omeprazole is superior to full-dose famotidine in maintenance therapy for gastroesophageal reflux disease, whereas “on-demand” famotidine is more effective for relief of episodes of heartburn. To explain this apparent discrepancy, intragastric pH was measured for 24-hr seven times in eight Japanese Helicobacter pylori-negative cytochrome P450 2C19 extensive metabolizers; on Days 1, 8, and 15 of repeated administration of 10 mg of omeprazole once daily and of 20 mg of famotidine twice daily and before medication. During repeated administration of omeprazole, mean intragastric pH and % time that intragastric pH > 4.0 were significantly higher and became greater. With famotidine, although these parameters were significantly higher, the degrees became smaller. Consequently, acid-suppressive effect was in the order; omeprazole < famotidine on Day 1, omeprazole≈famotidine on Day 8, and omeprazole >famotidine on Day 15. This discrepancy possibly results from the “potentiation” of acid-suppressive effect of omeprazole and the “tolerance” phenomenon in respect to famotidine.     

Selective hepatic vascular exclusion for the hepatic resection of HCC

BACKGROUND/AIMS: Selective hepatic vascular exclusion (SHVE) is an effective technique for the control of bleeding in major hepatic resections. Outcomes of the procedures of the SHVE group were compared with the non-SHVE group. METHODOLOGY: A retrospective study was carried out of 312 hepatic resections performed over a period of 10 years. The cases in this study were limited to Child's classification A, because of the rate of Child A in the SHVE group (n=82) was significantly higher than that within the non-SHVE group (n=158) (93% vs. 71%; p < 0.001). Preoperative factors, like age, gender, tumor size, intraoperative blood loss, operation time, and the postoperative course of the two groups were compared for both groups. RESULTS: The SHVE group showed significantly less blood loss, necessary blood transfusion, and a significant rate of severe postoperative complications. The rate of segmentectomy and subsegmentectomy in the SHVE group was higher than in the non-SHVE group, and the rate of partial hepatectomy and lobectomy in the non-SHVE group was higher than that in the SHVE group. Although the more difficult operations were performed in the SHVE group than in the non-SHVE group, there was no significant difference in the postoperative hospital stays in both groups. CONCLUSIONS: The SHVE technique is effective for bleeding control in major liver resections.
