BackgroundIn shoulder arthroplasty, bone resorption around the stem can lead to stem loosening and makes surgery difficult at the time of revision. Proximal bone resorption after reverse shoulder arthroplasty can cause instability because of a decrease of deltoid wrapping effect. As factors of the stem itself, such as stem coating, shape, length, and use of bone cement, may also affect bone resorption, a single-stem model should be used to compare bone resorptions between different pathologies and surgical procedures. However, to date, a few reports have compared these differences in detail using a single-stem model. Therefore, we investigated the prevalence and location of humeral bone resorption in a single-stem model.MethodsThe study included 100 shoulders that underwent anatomical total shoulder arthroplasty (TSA) or humeral head replacement (HHR) with a single uncemented humeral stem from 2008 to 2018. The patients were 31 men and 69 women. The mean age at surgery was 72.9 years (range, 41-86 years). The patients were divided into three groups: especially, 25, 61, and 14 shoulders received TSA for primary osteoarthritis without rotator cuff tears (TSA group), HHR using an anatomical head with rotator cuff repair for cuff tear arthropathy (CTA) (HHR group), and HHR using a CTA head without rotator cuff repair (CTA group), respectively. Patients were monitored for a mean of 56 months (range, 12-98 months). The location of bone resorption was divided into seven zones as follows: zone 1, greater tuberosity; zone 2, lateral diaphysis; zone 3, lateral diaphysis beyond the deltoid tuberosity; zone 4, tip of the stem; zone 5, medial diaphysis beyond the deltoid tuberosity; zone 6, medial diaphysis; and zone 7, calcar region. The degree of bone resorption was classified from grade 0 to 4.ResultsBone resorption of grade 3 or higher was significantly more frequent at the greater tuberosity in the HHR and CTA groups (P < .001 and P < .001, respectively) than that in the TSA group. Grade 4 bone resorption was significantly more frequent in the CTA than that in the TSA and HHR groups in zone 1 (P = .016 and P = .041, respectively).ConclusionThe state of attachment of the rotator cuff to the greater tuberosity might affect bone resorption at the greater tuberosity, such as the greater tuberosity after shoulder arthroplasty. In cases of shoulder arthroplasty for arthropathy with rotator cuff tear, performing rotator cuff repair might prevent bone resorption.Level of evidenceLevel IV; Prognosis Study 相似文献

Objective
Vascular sealing with an energy vessel sealing system during lung resection may allow surgeons to treat small vessels with minimal dissection, possibly decreasing likelihood of injury. Few large prospective trials have examined the proximal sides of vessels not ligated in addition to sealing during surgery. We therefore assessed feasibility of an energy device to seal pulmonary artery and vein branches without further ligation.Methods
This prospective, preoperative registration study at 2 institutions evaluated safety of energy sealing with the LigaSure (Medtronic, Minneapolis, Minn), with no additional reinforcing material such as suture ligation, for pulmonary vessels as large as 7 mm during anatomic lung resection (cohort 1 study). A postoperative hemorrhage occurred in the 128th case, so a cohort 2 study proceeded after we changed inclusion criterion for pulmonary arteries from a maximum of 7 mm to a maximum of 5 mm.Results
In cohort 1 (n = 128) and cohort 2 (n = 200), 216 and 250 pulmonary arteries and 189 and 213 pulmonary veins, respectively, were treated with energy sealing. Overall postoperative hemorrhage rate was 0.3% (1/328 patients); however, no serious postoperative complications were associated with energy sealing among the 200 patients in cohort 2. Subsequent inspection of the torn artery stump confirmed that the bleeding in the 128th case was in an area adjacent to the sealing zone.Conclusions
Energy sealing without reinforcement allows secure treatment during lung resection of pulmonary arteries as large as 5 mm in diameter and pulmonary veins as large as 7 mm. 相似文献6.

Treatment with tocilizumab (TCZ) to block interleukin-6 (IL-6) signalling is predicted to mitigate cytokine release syndrome (CRS) caused by coronavirus disease 2019 (COVID-19). However, the adverse effects of TCZ on patients with COVID-19 remain unclear. We herein report a patient with COVID-19 treated with TCZ who developed acute hypertriglyceridaemia. Despite favipiravir treatment, acute respiratory distress syndrome developed in a 45-year-old patient with COVID-19; thus, TCZ was initiated. The triglyceride levels greatly increased after TCZ administration. Physicians should consider the negative impact of TCZ on the lipid profile in patients with COVID-19, although COVID-19-induced CRS itself may be an aggravating factor. 相似文献

At present, almost all mountain tunnels in Japan are excavated and constructed utilizing
the New Austrian Tunneling Method (NATM), which was advocated by Prof. Rabcewicz of
Austria in 1964. In Japan, this method has been applied to tunnel construction since
around 1978, after which there has been a subsequent decrease in the number of casualties
during tunnel construction. However, there is still a relatively high incidence of labour
accidents during tunnel construction when compared to incidence rates in the construction
industry in general. During tunnel construction, rock fall events at the cutting face are
a particularly characteristic of the type of accident that occurs. In this study, we
analysed labour accidents that possess the characteristics of a rock fall event at a work
site. We also introduced accident prevention measures against rock fall events. 相似文献

A 62-year-old woman with activity-dependent two-to-one atrioventricular block (2:1AVB) and a normal left ventricular ejection fraction was referred to our department for the evaluation of exclusively exercise-induced marked symptoms. The treadmill test helped establish a clear correlation between 2:1AVB and symptoms. The test results demonstrated that exercise-induced marked symptoms were attributed to abrupt transient hypotension combined with relative bradycardia, probably due to increased diastolic mitral and tricuspid regurgitation because of 2:1AVB during moderate-to-heavy exercise. After pacemaker implantation for 2:1AVB, the symptoms and transient hypotension disappeared, and her exercise capacity improved. 相似文献
