STUDY DESIGN: A retrospective study. PURPOSE: To examine the efficacy and safety for a posterior-approach circumferential decompression and shortening reconstruction with a titanium mesh cage for lumbar burst fractures. OVERVIEW OF LITERATURE: Surgical decompression and reconstruction for severely unstable lumbar burst fractures requires an anterior or combined anteroposterior approach. Furthermore, anterior instrumentation for the lower lumbar is restricted through the presence of major vessels. METHODS: Three patients with an L1 burst fracture, one with an L3 and three with an L4 (5 men, 2 women; mean age, 65.0 years) who underwent circumferential decompression and shortening reconstruction with a titanium mesh cage through a posterior approach alone and a 4-year follow-up were evaluated regarding the clinical and radiological course. RESULTS: Mean operative time was 277 minutes. Mean blood loss was 471 ml. In 6 patients, the Frankel score improved more than one grade after surgery, and the remaining patient was at Frankel E both before and after surgery. Mean preoperative visual analogue scale was 7.0, improving to 0.7 postoperatively. Local kyphosis improved from 15.7degrees before surgery to -11.0degrees after surgery. In 3 cases regarding the mid to lower lumbar patients, local kyphosis increased more than 10degrees by 3 months following surgery, due to subsidence of the cages. One patient developed severe tilting and subsidence of the cage, requiring additional surgery. CONCLUSIONS: The results concerning this small series suggest the feasibility, efficacy, and safety of this treatment for unstable lumbar burst fractures. This technique from a posterior approach alone offers several advantages over traditional anterior or combined anteroposterior approaches.

We report on an apparently healthy woman in her 50s who noticed pain in the left side of her neck anteriorly and was prescribed an antimicrobial agent at a nearby clinic. However, she developed hypotension and hypoxemia and was brought to our hospital. Laboratory investigations revealed evidence of inflammation, and imaging findings showed low-density areas corresponding to the left lobe of the thyroid gland. The low-density areas extended to the superior mediastinum, raising suspicion of a thyroid gland mediastinal abscess. We performed inferior mediastinal drainage with video-assisted thoracoscopic surgery and resection of the left lobe of the thyroid gland. Culture of mediastinal aspirate yielded Streptococcus viridans. Based on these findings, the final diagnosis was descent-related mediastinitis secondary to acute suppurative thyroiditis.

An 82 year-old-woman was referred to our hospital because of infiltrative shadow of the lingula in 201X. She was asymptomatic, so we followed up with imaging observation. After 1 year, the infiltrative shadow had progressed, so we performed bronchoscopy. Glandular epithelium with the mild aberrant type was detected, but did not lead to a definitive diagnosis. There was increased eosinophilic compartmentalization of immune response in the bronchoalveolar lavage, so we started treatment with corticosteroids for chronic eosinophilic pneumonia. However, there was no improvement of the shadow. Subsequent computed tomography-guided lung biopsy revealed evidence of papillary adenocarcinoma.

From April 2009 to April 2017, we experienced on average 40 cases of spontaneous pneumothorax per year at our hospital, but we encountered only 2 cases of nontraumatic hemopneumothorax over the entire 8-year period. In one of these cases, we performed transcatheter artery embolization. Extravasation of contrast media was observed on CT near the apex of the lung, and angiography revealed the culprit vessel. We performed embolization and were able to achieve hemostasis and symptomatic improvement. However, hemopneumothorax recurred as a result of adhesion tear due to re-collapse of the lung and required surgical treatment. In this report, we describe our experience of this relatively rare condition and discuss the case with reference to the literature.

Pneumonia is common among elderly patients and the incidence among older adults is increasing in aging societies. If pulmonologists were to treat all cases of pneumonia, their work volume would be immense and the risk of burnout would increase. We reviewed cases of consecutive patients 70 years of age or older who were treated for pneumonia between November 2017 and October 2018 at Akita Kousei Medical Center. Of a total of 372 patients recruited for this study (214 men, mean age 85.6 years), 288 patients recovered and 84 (29.2%) died. The duration of admission differed significantly between the cardiovascular department and surgery department (p=0.03), between the renal unit of the internal medicine department and the neurosurgery department (p=0.01), and the renal unit of the internal medicine department and the surgery department (p=0.0005). Outcome was not significantly different among departments. It is crucial that pulmonologists and non-pulmonologists collaborate to treat pneumonia in old adults.

A woman in her 60s was being treated for diabetes and hypertension but had impaired activities of daily living (ADL) due to severe obesity (150 kg). She was transported to the emergency department because of disturbance of consciousness in August 201X. Imaging findings showed decreased permeability of the whole right lung field. She was intubated and started on ceftriaxone plus levofloxacin for severe infection with respiratory failure. Erysipelothrix rhusiopathiae was detected in blood cultures, leading to a diagnosis of sepsis due to a large pressure ulcer on the posterior aspect of the thigh. We switched levofloxacin to clindamycin and continued medical treatment, and she was extubated on the 10th day of illness. However, type 2 respiratory failure was prolonged because of alveolar hypoventilation due to obesity and she required noninvasive positive pressure ventilation. Also, she had difficulty getting out of bed due to obesity, disuse syndrome, and pressure ulcer. Cooperation among staff from many professions, including respiratory nursing, intensive care nursing, wound, ostomy and continence nursing, physical therapy, and nutrition management, led to improvement of ADL and weight loss (to 109 kg), allowing her to be transferred out of the intensive care unit.
