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.

Background/Aims:
Endoscopic ultrasound gallbladder drainage (EUS-GBD) is gaining attention as a treatment method for cholecystitis. However, only a few studies have assessed the outcomes of permanent stenting with EUS-GBD. Therefore, we evaluated the clinical outcomes of permanent stenting using EUS-GBD.
Methods:
This was a retrospective, single-center cohort study. The criteria for EUS-GBD at our institution are a high risk for surgery, inability to perform surgery owing to poor performance status, and inability to obtain consent for emergency surgery. EUS-GBD was performed using a 7-Fr double-pigtail plastic stent with a dilating device. The primary outcomes were the recurrence-free rate of cholecystitis and the late-stage complication-avoidance rate. Secondary outcomes were technical success, clinical success, and procedural adverse events.
Results:
A total of 41 patients were included in the analysis. The median follow-up period was 168 (range, 10–1,238) days. The recurrence-free and late-stage complication-avoidance rates during the follow-up period were 95% (38 cases) and 90% (36 cases), respectively. There were only two cases of cholecystitis recurrence during the study period.
Conclusions
EUS-GBD using double-pigtail plastic stent was safe and effective with few complications, even in the long term, in patients with acute cholecystitis.

Objective: This study investigated the relationship between occupations and health status to obtain an overall understanding of a cohort of Japanese middle-aged women, including unemployed women, who comprised approximately 30% of the sample.Participants and Methods: Participants of this study were 4,454 women aged 40–69 years, classified into the following five groups based on their occupation: unemployed, 1,432; agriculture, 439; self-employed, 1,596; white collared, 793; and blue collared, 194. Participants’ perceived health was assessed using a symptoms checklist called the Todai Health Index (THI, later renamed as the Total Health Index) in a baseline survey conducted in 1993. The mortality risk of the participants was assessed using the Cox’s Proportional Hazards Model.Results: The means of the percentile values on the Total Scale 1 in the THI were as follows: agriculture, 43.7; unemployed, 50.8; self-employed, 52.5; white collared, 53.0; and blue collared, 56.1, with lower percentile values indicating better perceived health. The results showed that women engaged in agriculture were in significantly better health than were those in the other four occupations. The hazard ratios (HRs) and 95% confidence intervals of the occupational groups adjusted for age, area of residence, and Total Scale 1 scores were as follows: agriculture (reference group), 1; white collared, 1.16 (0.77–1.74); self-employed, 1.25 (0.87–1.78); unemployed, 1.27 (0.91–1.77); and blue collared, 1.50 (0.86–2.60).Conclusions: Women engaged in agriculture had a significantly higher tendency to have a better health status on the THI as compared to those from the other four occupational groups, and they exhibited the lowest HR as compared to their counterparts, though not statistically significant. We concluded that the perceived health status of unemployed women was similar to that of women engaged in agriculture.
