Persistent sciatic artery (PSA) is a rare congenital peripheral artery disorder that is usually detected incidentally on computed tomographic examination. PSA can also cause iliac aneurysm and acute thromboembolism, which are potentially associated with rest pain, claudication, and limb-threatening ischemia. Patients with PSA and leg ischemia should be treated with revascularization and appropriate management of PSA aneurysm. The authors often choose emergent bypass surgery or endovascular intervention for aneurysmal rupture and acute lower-extremity arterial occlusion. This report describes an emergency procedure using catheter-based thrombolysis for acute limb ischemia in a patient with PSA.

Popliteal artery aneurysm (PAA) is a rare vascular disease, especially in women, and presents with various symptoms, ranging from being asymptomatic to rupture or acute life-threatening ischemia. We have presented a case of PAA in an 81-yearold woman complaining of tingling sensations in her leg. Computed tomography revealed a large 10-cm sized PAA. Because of the compression related symptoms, an open repair approach was selected and performed successfully via a posterior approach, including partial aneurysm resection and interposition graft with a reversed saphenous vein.

Results:
The study included 101 patients (84 females) with a median follow-up period of 23.6±14.2 months. The persistence rate declined to 85.3%, 78.3%, 74.1%, 71.3%, and 69.3% at 12, 24, 36, 48, and 60 months, respectively. Age at the initiation of denosumab therapy differed significantly between non-persistent (n=31) and persistent (n=70) patients (81.3 vs. 72.8 years, p <0.01). Persistence was significantly lower in patients aged ≥80 years than in those aged <60 and 60–79 years (both p <0.01). The reasons for non-persistence of denosumab therapy were transfer to another hospital (n=13), interruption of outpatient visits (n=11), dental treatment (n=4), adverse events (n=2), and patient request (n=1).
Conclusions
Persistence was significantly lower in patients aged ≥80 years than in patients of other ages, and strategies promoting persistence are needed for these elderly patients.

Asian Spine Journal 2020;14(6):801-807
Methods:
The subjects were 23 children with LLD ≥20 mm (range, 27–65 mm) treated at Nagoya University Hospital between 2007 and 2017. Whole spine posteroanterior standing radiographs and whole lower limb radiographs in a supine position were recorded. Data were collected for demographics, LLD, Cobb angle, pelvic obliquity, and Nash/Moe index. Scoliosis was defined as a Cobb angle ≥10°. Leg length was measured from the top of the femoral head to the middle of the tibial plafond, and LLD was defined as the difference between the left and right leg lengths.
Results:
The patients (nine males and 14 females) had a mean age of 14.0 years (range, 5–18 years). The average LLD was 44.3±17.2 mm, with LLDs of 20 to 39 mm, 40 to 59 mm, and ≥60 mm in 13, five, and five subjects, respectively. The average Cobb angle was 13.0°±7.0°, and 15 subjects (65%) had scoliosis. Convexity of the scoliosis was to the short leg side in all cases. The Cobb angle was significantly related to the severity of the LLD (R=0.736, p<0.01), pelvic obliquity (R=0.966, p<0.01), and Nash/Moe index (p<0.05).
Conclusions
LLD is a common pediatric condition that can cause scoliosis of the spine. Severe scoliosis may develop if the LLD is ≥30 mm. Long-term studies are needed to examine the effect of LLD resolution on the elimination of scoliosis.

A 66-year-old man was admitted to our intensive care unit because of severe pneumonia. He was treated with mechanical ventilation, antibiotics, and corticosteroids, but muscle weakness developed rapidly. His muscle strength declined to a Medical Research Council scale sum score of 18/60;thus, a diagnosis of intensive care unit-acquired weakness (ICU-AW) was made. The results of nerve conduction studies were compatible with critical illness polyneuropathy. Mechanical ventilation was required for 95 days because of continuous respiratory failure. Rehabilitation began at 48 hours after hospitalization and was continued to prevent immobilization even when he was mechanically ventilated. However, orthostatic hypotension developed and inhibited mobility training. Physical and occupational therapies provided muscle strengthening exercises followed by a progressive mobility program that assisted him to raise his head, sit on the edge of the bed, and stand up. The intervention was performed within safety criteria of vital signs and the rating of perceived exertion (RPE) Borg scale between 11 and 13. It resulted in the attenuation of orthostatic hypotension and the recovery of muscle strength. He finally achieved independence in activities of daily living and the ability to walk without help after 271 days of admission. This case report suggests that long-term rehabilitation within safety criteria of vital signs and RPE Borg scale between 11 and 13 is safe and feasible without overuse weakness for ICU-AW with orthostatic hypotension.

The treatment tactics for subclavian artery occlusion include the more commonly used endovascular therapy rather than surgical intervention. We present a case of a 61-year-old woman with dialysis-dependent chronic renal failure who experienced left finger necrosis in the left upper extremity. To salvage the limb, we performed femoro-axillary (fem-ax) artery bypass using an autologous saphenous vein graft. However, 10 months later, she experienced coldness in the left forearm. Angiography revealed chronic total occlusion of the venous bypass. Despite emergent thrombectomy, redo fem-ax artery bypass operation was performed using a prosthetic graft. Upper limb salvage can be achieved by fem-ax artery retrograde bypass.

STUDY DESIGN: Animal study. PURPOSE: To review the present warning point criteria of the compound muscle action potential (CMAP) and investigate new criteria for spinal surgery safety using an animal model. OVERVIEW OF LITERATURE: Little is known about correlation palesis and amplitude of spinal cord monitoring. METHODS: After laminectomy of the tenth thoracic spinal lamina, 2-140 g force was delivered to the spinal cord with a tension gage to create a bilateral contusion injury. The study morphology change of the CMAP wave and locomotor scale were evaluated for one month. RESULTS: Four different types of wave morphology changes were observed: no change, amplitude decrease only, morphology change only, and amplitude and morphology change. Amplitude and morphology changed simultaneously and significantly as the injury force increased (p<0.05) Locomotor scale in the amplitude and morphology group worsened more than the other groups. CONCLUSIONS: Amplitude and morphology change of the CMAP wave exists and could be the key of the alarm point in CMAP.

Purpose: A report of effective occupational therapy for delirium patients with cancer is uncommon. We report a patient of carcinomatous meningitis, in whom her daily activity is improved by occupational therapy. Case: Firstly, we supported her meals and then started occupational therapy accepting her interest. Although degree of confusion and her performance status was not varied from beginning to end, she could concentrate our programmed works and change her way of feelings. Also occupational therapy promotes reminiscence about her life review and friendship among other patients even in delirium condition. Conclusion: Occupational therapy can reduce cancer patients' impatience, anxiety and solitary feelings and improve quality of life.

We examined how difficult it would be for the elderly living in mountainous areas to go to the nearest hospital using a Voronoi tessellation representing the mathematical concept of neighborhood. We defined the index of the nursing-care capacity for the elderly as the ratio of the number of caregivers to the number of the elderly receiving nursing-care.
The mean age of those who drive to the hospital by themselves worked out at 70±9.8 years. Meanwhile, that of those who go to the hospital by bus or taken to hospital in a car driven by a family member came to 80±7.0years. The latter was significantly older than the former.
The areas of the Voronoi tessellation generated by patients' places of residence were divided into three groups according to the size. The plots of these three groups of the the places of residence on the map had a three-layer and doughnut-like structure, i. e., inner-, middle-, and outer-layer.
The index of the nursing-care capacity in 2008 was less than 1.0 for the patients under 80 years of age. This means that when those who were at the age of 50 in 2008 become old and need nursing-care, access to the hospital will become harder to them than at present. For those who are over 80 years of age and live in the outer layer that is far away from arterial road, it will be almost impossible.
These findings suggest that outpatient care with transportation assistance by a family member at present should be reconsidered because of the future lack of care personnel. It would also be necessary to consider the welfare of older people from the geographical point of view in order to manage the problems concerning the various physical and sociological difficulties of the elderly.
