Surgical treatment of syphilitic ascending aortic aneurysm: a case report

A 67-year-old man with positive serum reaction for syphilis had been followed by cardiologist for his moderate-sized saccular ascending aortic aneurysm and small-sized abdominal aortic aneurysm. Because of his transient ischemic attack probably secondary to the thrombo-embolism of the aneurysm and rapid growing of its size, surgical treatment was recommended. Resection of the saccular aneurysm with patch plasty of the ascending aorta was performed under the cardiopulmonary bypass associated with right side cerebral perfusion. At the time of operation, the mildly dilated ascending aorta and arch with multiple intimal ulceration were noted. Although his postoperative hemodynamic condition was stable, he suffered from multiple cerebral infarction, probably due to embolism migrated from the fragile aortic intima. His neurological condition was improved promptly, trivial hemi-paralysis was remained. The specimen of resected aneurysmal wall revealed syphilitic changes microscopically. We concluded that the extent of the aortic replacement with prosthetic graft should be deceived not only with its external appearance, but also with the changes of its inside.

Predictors of postoperative early recurrence of extrahepatic bile duct cancer

Resected bile duct cancers often relapse during postoperative follow-up. The aim of this study was to detect predictors of early recurrence in patients with extrahepatic bile duct cancer. Consecutive cases (n = 162) of extrahepatic bile duct cancer in which R0 or R1 resection was achieved in Kobe University Hospital between 2000 and 2016 were divided into three groups [early recurrence (ER), within 6 months of surgery, late recurrence (LR), and no recurrence (NR)] and their clinicopathological features were compared. Twenty-two patients (14%) developed ER and 69 (43%) developed LR after surgery. The rates of lymph node metastasis and residual cancer status were similar in all three groups. Liver metastasis was more common in the ER group than in the LR group (59% vs. 32%, p = 0.02). ER had a significantly worse prognosis than LR and NR (7% vs. 44% vs. 85% at 1 year, p < 0.01, respectively). Multivariate analysis showed that age > 75 years, serum CA19-9 > 1008 U/ml and perineural invasion were independent predictors of early recurrence. High serum CA19-9 values (> 1008 U/ml) were an independent predictor of early recurrence. Neoadjuvant therapy and aggressive adjuvant therapy may be beneficial for patients who show highly elevated CA19-9 values before surgery.     

Selective high dose gamma-globulin treatment in Kawasaki disease: Assessment of clinical aspects and cost effectiveness

BACKGROUND: High-dose intravenous gamma-globulin (IVGG) plus aspirin (ASA) treatment is effective in preventing coronary artery complications in acute Kawasaki disease (KD). However, gamma-globulin is very expensive, especially in Japan. Furthermore the indication for IVGG treatment and the optimal dose of gamma-globulin remain controversial. OBJECTIVES: To examine these two issues, we used Harada's scoring system to investigate whether a single 2 g/kg dose therapy has any advantage over the 5 day 400 mg/kg per day therapy. METHODS: We studied 203 patients with KD who had no coronary artery complications on admission. Of these, 145 patients scored 4 or more on Harada score within the first 9 days of illness and were treated with IVGG treatment. Using a random number table, 72 patients were selected to receive a single 2 g/kg dose (2 g group), while the remaining 73 patients were treated with 400 mg/kg per day for 5 consecutive days (400 mg group). Those who had a Harada score of three or less received no IVGG (non-IVGG group) treatment (58 patients). RESULTS: The incidence rate of coronary artery complications in the 2 g group was significantly lower than in the 400 mg group. The duration of high fever, positive duration of C-reactive protein and the number of hospital days in the 2 g group were each significantly shorter than in the 400 mg group. The total medical expense in the 2 g group was significantly lower than in the 400 mg group. There were no coronary artery complications in the non-IVGG group. CONCLUSIONS: It was found to be clinically more effective and more cost effective to select a patient by Harada's scoring system and, where a score of four or more was obtained, to administer a single 2 g/kg intravenous dose of gamma-globulin for acute KD.     

Core lower urinary tract symptom score (CLSS) for the assessment of female lower urinary tract symptoms: a comparative study

Objective: We have recently developed the core lower urinary tract symptom score (CLSS) questionnaire to readily address 10 important lower urinary tract symptoms (LUTS). The aim of the present study was to evaluate the performance of the CLSS in women compared with the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). Methods: Three hundred and eighteen treatment‐naïve consecutive female patients, including 48 controls, completed the three questionnaires. Quality of life (QOL) was determined as per the IPSS QOL Index. The clinical diagnoses were overactive bladder (n = 69), mixed incontinence (n = 42), stress incontinence (n = 17), pelvic organ prolapse (n = 56), interstitial cystitis (n = 31), bacterial cystitis (n = 16), underactive bladder (n = 16), and “other” (n = 23). Simple statistics and the relationship between symptom scores and poor QOL (QOL Index ≥4) were examined. Results: All symptom scores were significantly increased in symptomatic women. The CLSS described the symptom profiles of patients with distinct conditions. The scores of corresponding symptoms on the three questionnaires were significantly correlated (r = 0.51–0.85; all P < 0.0001). Multivariate logistic regression modeling proved five CLSS symptoms (daytime frequency, nocturia, urgency incontinence, straining, and urethral pain) as independent predictors of poor QOL, with hazard ratios ranging from 2.0 to 4.2. The IPSS included only two (urgency and straining) significant symptoms. Conclusions: The IPSS alone does not fully evaluate female LUTS, with a possible negative impact on QOL. Using the CLSS questionnaire would enable a simple and comprehensive assessment of female LUTS.     

Midurethral autologous fascial sling surgery with reconstruction of the lower abdominal wall using the tensor fascia lata muscle flap for post‐hemipelvectomy stress urinary incontinence

Hemipelvectomy is surgery for pelvic bone neoplasms. In the case of pubic bone osteosarcoma, the distal end of the rectus abdominis muscle is severed from the pubic and ischium bones, and the pelvic floor muscles are resected en bloc with the bone, which leads to stress urinary incontinence. Cancer control is prioritized over complications, and stress urinary incontinence is generally disregarded. A 25‐year‐old woman presented with stress urinary incontinence. She had undergone a hemipelvectomy for left pubic bone osteosarcoma, and stress urinary incontinence appeared and persisted since the surgery. We carried out a reconstruction of the tissue deficit of the rectus abdominis using the tensor fascia lata muscle flap simultaneously with a midurethral autologous fascial sling anchoring to the tensor fascia lata flap. Stress incontinence was successfully improved without morbidity. This is the first reported case of midurethral suspension with reconstruction of the lower abdominal wall with the tensor fascia lata flap for post‐hemipelvectomy stress urinary incontinence.     

Long-Term Outcomes and Prognostic Factors with Reductive Hepatectomy and Sequential Percutaneous Isolated Hepatic Perfusion for Multiple Bilobar Hepatocellular Carcinoma

Background

Sorafenib is currently recommended as first-line therapy for patients with intermediate or advanced hepatocellular carcinoma (HCC) per Barcelona Clinic Liver Cancer staging. However, the median overall survival (OS) with sorafenib in these patients is 10.7 months with an overall response rate of 2 %. We retrospectively investigated the long-term outcomes and prognostic factors with reductive hepatectomy and sequential percutaneous isolated hepatic perfusion (PIHP) for refractory intermediate or advanced HCC.

Methods

A total of 68 patients who had intermediate or advanced stage HCC without extrahepatic metastases were scheduled for reductive hepatectomy plus PIHP. All patients underwent reductive hepatectomy and PIHP with mitomycin C 20–40 mg/m² and/or doxorubicin 60–120 mg/m² 1–3 months after surgery (mean, 1.51 times/patient).

Results

The objective response rate of PIHP was 70.6 % (complete plus partial response). The median OS of all 68 patients was 25 months, and the 5-year OS rate was 27.6 %. Univariate and multivariate analyses indicated that tumor response to PIHP and normalization of serum des-γ-carboxy prothrombin concentrations after PIHP were independent prognostic factors for OS.

Conclusions

The median OS of the study population treated by reductive hepatectomy and sequential PIHP was 25 months. This treatment strategy can offer a possible curative treatment to patients with refractory intermediate and advanced HCC.     

Improvement in blastocyst hatching of mouse embryos cocultured with human placental cells

Purpose Although the hatching of embryos is an important phenomenon, the mechanism of hatching remains controversial. Therefore, we attempted to develop a new coculture system with human placental cells to investigate the hatching of mouse embryos.Results In our new system there was no difference in development from the two-cell stage to blastocysts between embryos cultured with a T6 medium and embryos cocultured with human placental cells at 1 × 10⁵, 5 × 10⁵, and 1 × 10⁶ cells/ml. However, the hatching-rate cell number increased significantly in embryos cocultured with placental cells compared to embryos cultured without placental cells. [³H]Thymidine uptake did not show any significant difference from the beginning of in vitro culture to the hatching stage between the coculture group and the control group. Nevertheless, the [³H]uridine uptake was significantly different in the two groups, measuring 2167 ± 532 cpm/10 embryos in the coculture group and 804 ± 86 cpm/10 embryos in the control group at 114 hr after human chorionic gonadotropin injection (P < 0.01).Conclusion These results therefore seem to indicate that the hatching of blastocysts depends on the protein synthesis of the embryos and not on DNA duplications.     

Extended observation of the nasal cycle using a portable rhinoflowmeter

OBJECTIVE: Nasal patency varies owing to the effects of humidity, temperature, and exercise. In addition, periodic cycles of congestion and decongestion that alternate between the right and the left side of the nose, which are termed the "nasal cycle," have been observed. The physiologic mechanisms underlying this cycle are not clear. Sympathetic nerves that supply the nose are regulated by the hypothalamus and the vasomotor areas of the brainstem. It is possible that the nasal cycle could be involved in protection against respiratory infection or allergies. Conventional methods of studying the nasal cycle, including rhinomanometry and acoustic rhinometry, impose limitations on the location and timing of evaluation. We studied the nasal cycle using a new portable device for relatively long-term rhinoflowmetry. METHODS: Twenty normal subjects aged 24 to 77 years were fitted with the portable rhinoflowmeter (Rhinocycle, Rhinometrics, Lynge, Denmark) to continuously measure nasal air flow via each nostril over 12 daytime hours. RESULTS: No subject complained of discomfort owing to the device, and 14 of them showed a detectable nasal cycle. The mean nasal cycle duration was 110 minutes, although variation was considerable, even in a single subject. CONCLUSIONS: The portable device proved useful for observing the nasal cycle, and it should be valuable for the general investigation of nasal physiology.     

Simultaneous double or triple coil technique for closure of moderate sized (> or = 3.0 mm) patent ductus arteriosus

One important complication of coil occlusion of patent ductus arteriosus using the conventional Gianturco coil is migration of coils into peripheral vessels. Especially in patients having relatively larger size ductus, the risk for such complication could be increased. In this regard, a detachable coil may have some technical benefits in performing coil occlusion and reducing the incidence of complications such as migration of coil. Based on our clinical experiences, we describe the clinical efficacy of a simultaneous double or triple coil occlusion technique using the Cook detachable coil system to close the ductus arteriosus, especially in patients whose ductus diameter more than 3.0 mm.
