This report illustrates a case of chronic inflammatory demyelinating polyneuropathy (CIDP) masquerading as neurofibromatosis caused by multifocal enlargements of spinal nerve roots. At age 73, the patient reported a 6-year history of numbness, weakness and pain in the hands and legs, but he could but he could walk independently with a cane. And although tremor was present, he could still draw. T2-weighted magnetic resonance imaging (MRI) through the cervical spine demonstrated spinal cord compression bilaterally at C 6-7, caused by neurofibroma-like cervical root tumors and enlargement of the spinal nerve roots and the brachial and lumbosacral nerve plexuses. Nerve conduction studies showed very little evoked response, with the exception of the median nerve which demonstrated prolonged distal latency and reduced compound muscle action potential with temporal dispersion, suggesting a diagnosis of demyelinating neuropathy. Somatosensory evoked potentials of the median nerve revealed prolonged latency, and motor evoked potentials obtained from the abductor pollicis brevis and abductor digiti minimi by transcranial magnetic stimulation demonstrated prolonged latency and temporal dispersion. Sural nerve biopsies showed segmental demyelination, remyelination (onion-bulb formation), axonal loss, and lymphocyte infiltration suggesting CIDP. The patient did not have a positive family history and declined further genetic studies. We could therefore not rule out the possibility of a hereditary hypertrophic neuropathy such as Charcot-Marie-Tooth disease.

Postoperative infections should be comprehensively controlled in the context of infection control, rather than as activities of individual surgeons. We started a surgical site infection (SSI) surveillance program in 2009 in which prophylactic measures for preventing SSIs were applied. These measures were as follows : 1) screening for nasal carriage of methicillin-resistant Staphylococcus aureus ; 2) dental checks and oral screening ; 3) antibiotic prophylaxis in the intra- and postoperative period ; 4) control of glucose levels to ≤160 mg/dl in the immediate postoperative period ; and 5) early removal of surgical drain. After the introduction of prophylactic measures, we reexamined SSI surveillance and added the following prophylactic measures at the beginning of 2011 : 6) data concerning SSI and compliance with prophylactic measures for all surgical and ward staff were published monthly, and the Infection Control Team (ICT) and surgeons performed weekly ward visits to assess SSIs ; 7) recommendations were made for wearing two pairs of gloves and surgical hoods to cover the hair, scalp, ears and neck ; and 8) collaboration with diabetologists was implemented to control glucose levels in diabetics. We compared incidences of SSI in cardiovascular surgery from the periods before (469 cases, Group B) and after (118 cases, Group A) introduction of the additional prophylactic measures. Clinical characteristics of patients in each group did not differ significantly. Operative time was significantly shorter in Group A (400±116 min) than in Group B (434±145 min). Compliance with antibiotic prophylaxis in the intraoperative period improved progressively from 93% in Group B to 99% in Group A. Compliance with control of glucose levels to ≤160 mg/dl on postoperative day 1 improved progressively from 71% in Group B to 81% in Group A. Duration of drain placement was significantly shorter in Group A (2.9±1.8 days) than in Group B (3.6±2.9 days). Incidence of SSI decreased significantly from 6.0% in Group B to 0.8% in Group A. Revision of preventive measures based on the results of surveillance and enhancement of cooperation between the ICT and surgeons could help to decrease the incidence of SSI.

Background/Aims:
Hybrid endoscopic submucosal dissection (ESD), in which an incision is made around a lesion and snaring is performed after submucosal dissection, has some advantages in colorectal surgery, including shorter procedure time and preventing perforation. However, its value for rescue resection in difficult colorectal ESD cases remains unclear. This study evaluated the utility of rescue hybrid ESD (RH-ESD).
Methods:
We divided 364 colorectal ESD procedures into the conventional ESD group (C-ESD, n=260), scheduled hybrid ESD group (SH-ESD, n=69), and RH-ESD group (n=35) and compared their clinical outcomes.
Results:
Resection time was significantly shorter in the following order: RH-ESD (149 [90–197] minutes) >C-ESD (90 [60–140] minutes) >SH-ESD (52 [29–80] minutes). The en bloc resection rate increased significantly in the following order: RH-ESD (48.6%), SH-ESD (78.3%), and C-ESD (97.7%). An analysis of factors related to piecemeal resection of RH-ESD revealed that the submucosal dissection rate was significantly lower in the piecemeal resection group (25% [20%–30%]) than in the en bloc resection group (40% [20%–60%]).
Conclusions
RH-ESD was ineffective in terms of curative resection because of the low en bloc resection rate, but was useful for avoiding surgery.

This study describes the first case of biliary peritonitis after radiofrequency ablation diagnosed by magnetic resonance (MR) imaging with gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA), a hepatocyte-specific MR imaging contrast agent. The image acquired 300 minutes after the administration of Gd-EOB-DTPA was useful to make a definite diagnosis and to identify the pathway of bile leakage. It is important to decide on the acquisition timing with consideration of the predicted location of bile duct injury.

Objective:
This study aimed to investigate the accuracy and precision of continuous, non-invasive blood pressure obtained using the ClearSight system by comparing it with invasive arterial blood pressure, and to assess the hemodynamic changes using invasive methods and the ClearSight system in patients undergoing cesarean section.
Methods:
Arterial pressure was measured invasively with an intra-arterial catheter and non-invasively using the ClearSight system during cesarean section in patients with placenta previa or placenta accreta. Blood pressure measurements obtained using these two means were then compared.
Results:
Total 1,277 blood pressure measurement pairs were collected from 21 patients. Under Bland-Altman analysis, the ClearSight system demonstrated an acceptable accuracy with a bias and standard deviation of 8.8±13.4 mmHg for systolic blood pressure, -6.3±7.1 mmHg for diastolic blood pressure, and -2.7±8.0 mmHg for median blood pressure. Cardiac index levels were significantly elevated during fetal delivery and 5 minutes after placental removal, and systemic vascular resistance index levels were significantly decreased during fetal delivery and 40 minutes after placental removal.
Conclusion
In patients undergoing cesarean section, the ClearSight system showed excellent accuracy and precision compared to that of the currently used invasive monitoring system.

The patient was a 44-year-old man with right facial paralysis as the main complaint. Upon resection of a benign parotid gland tumor (6 cm in diameter), one of the buccal branches of the right facial nerve was severed. Immediately after the surgery, facial nerve paralysis occurred in the areas innervated by the buccal and marginal mandibular branches. Therefore, on the 5th day after the surgery, acupuncture was started. The paralyzed facial site was treated weekly for 15 minutes by inserting a disposable acupuncture needle (40 mm in length and 0.16 mm in thickness) about 5 mm deep into the site. As a result, the discomfort around the right ear was alleviated and the right facial nerve paralysis was gradually improved and cured in 6 months after the onset. Acupuncture may have prevented secondary changes such as tissue scarring and atrophy after the surgery, and promoted healing. The paralysis of the areas innervated by the buccal branches may have been improved through rerooting from the other branches in the periphery region of the neurectomy site. The present case is informative in considering the indications of acupuncture.
