Immediate effects of stretching on trunk functions using a stretch pole half-cut

[Purpose] To analyze the immediate effects of stretching on respiratory and trunk functions using a stretch pole half-cut in healthy male participants. [Participants and Methods] Thirty healthy male participants with a mean age of 21.1 ± 0.8 years were recruited in this study. The participant had to lay on his back on the convex surface of the pole with the semicircle of the pole touching the surface of the platform mat. The convex of the pole was placed at the level from seventh to 10th thoracic vertebra for 4 min and was applied perpendicular (anatomically horizontal) to the body axis. Respiratory function and muscle strength using a spirometer with attached units, maximum-minimum chest wall expansion difference using a tape measure, and body alignment, such as angles obtained from the spinal mouse, were measured before and immediately after the intervention in random order. [Results] The total inclination angle was found to decrease significantly, while the thoracic kyphosis angle and maximum inspiratory pressure showed a significant increase. [Conclusion] This intervention was suggested to be easy for incorporating into day life and useful in situations where the subjects want to increase the maximum inspiratory pressure, such as in sports.     

Prognostic Significance of Immunohistochemically Detected Blood and Lymphatic Vessel Invasion in Colorectal Carcinoma: Its Impact on Prognosis

Background The prognostic significance of blood vessel invasion (BVI) and lymphatic vessel invasion (LVI) is unclear. Because of the absence of specific markers for venous and lymphatic vessels, earlier studies could not reliably distinguish between BVI and LVI. Methods By immunostaining for podoplanin and CD34 antigen, we retrospectively investigated LVI and BVI in 419 tissue specimens of colorectal carcinoma. We performed univariate and multivariate analysis of the clinicopathologic features, frequency of recurrence, and outcome of patients with or without LVI and BVI. Results The use of hematoxylin and eosin (H&E) staining to identify BVI and LVI yielded a false positive rate of 9.1% and false negative rate of 12.6%. The incidence of BVI was significantly higher among tumors with LVI than tumors without LVI (P <.001). In logistic multivariate analysis, only LVI (P < .001) was associated with lymph node metastasis and BVI (P = .015) was associated with distant recurrence. Calculating the prognostic relevance, both two invasion types correlated with decreased survival in univariate analysis (both P <.001). In multivariate analysis, BVI (P =.024), lymph node status (P =.003) and tumor stage (P <.001) remained statistically significant factors for survival. Conclusions Our results suggest that immunohistologic evaluation of BVI and LVI could be useful in colorectal carcinoma indicating the risk of lymph node metastasis and recurrence, thereby contributing to prognostic evaluation.     

Surgical Treatment for Biliary Carcinoma Arising After Pancreatoduodenectomy

The clinicopathological features and surgical treatment of biliary carcinoma around the major hepatic duct confluence arising after pancreatoduodenectomy (PD) due to initial bile duct carcinoma are described in three patients. Occurrence of biliary carcinoma more than 12 years after initial surgery and a histological finding of cholangiocellular carcinoma mixed with hepatocellular carcinoma suggested metachronous incidence of biliary carcinoma after PD. Extended right hemihepatectomy with complete removal of the residual extrahepatic bile duct and segmental, resection of the jejunal loop were carried out safely without operative death or severe postoperative complications. Two patients died of tumor recurrence 6 months after surgery, and the remaining patient is currently living a normal life without evidence of recurrence 17 months after surgery. These surgical procedures are a therapeutic option in patients with biliary carcinoma around the major hepatic duct confluence arising after PD.     

Mitral valve repair for mitral insufficiency due to infective endocarditis in a patient with idiopathic thrombocytopenic purpura.

A 63-year-old woman with an 18-year history of idiopathic thrombocytopenic purpura (ITP) was admitted with a persistent fever of unknown cause. Blood culture was positive for alpha-Streptococcus and echocardiography revealed severe mitral regurgitation and vegetation on the mitral valve. After antimicrobial therapy for six weeks, she underwent mitral valve repair using a Cosgrove ring. The platelet count increased and remained stable by perioperative treatment with intravenous high-dose gamma-globulin and platelet transfusion without steroids therapy or splenectomy. The hospital course was uneventful. Perioperative high-dose gamma-globulin therapy and platelet transfusion for the cardiac operation were useful to increase and maintain the platelet count for an ITP patient complicated with infective endocarditis.     

Anesthesia for electroconvulsive therapy during pregnancy--a case report

We experienced anesthetic management for ECT in a patient with psychiatric disease during the third trimester of pregnancy. The 24 year-old patient had been on oral antipsychotics prescribed to treat schizophrenia for ten years. Her signs and symptoms deteiorated during pregnancy in spite of increased doses of antipsychotics. With tocolytic agent administered intravenously, anesthesia was induced by intravenous thiamylal immediately followed by intravenous suxamethonium for muscle relaxation. Alternative current was applied on both side of the head after the sufficient anesthesia had been obtained. The patient received intermittent mandatory ventilation by breathing mask with 100% oxygen during the procedure. Along with monitoring of maternal hemodynamic variables and arterial oxygen saturation (Spo2), fetal heart rate and uterine contraction were recorded by cardiotocogram throughout the procedure. At the first two treatments, the patient showed neither significant uterine contraction nor fetal heart rate changes. At the third treatment, continuous uterine contraction refractory to tocolysis was recorded for six minutes, resulting in fetal bradycardia. At the sixth treatment, general anesthesia was induced and maintained by sevoflurane in oxygen followed by suxamethonium for muscle relaxation. The uterine contraction was remarkably diminished and fetal heart rate remained unchanged during the procedure. In conclusion, inhalation anesthesia is beneficial for ECT in the last stage of pregnancy to reduce uterine contraction by potential uterine relaxation effect of anesthetics.     

Intrahepatic Cholangiocarcinoma: Clinicopathological Differences Between Peripheral Type and Hilar Type

Background  

Intrahepatic cholangiocarcinoma (ICC) is categorized as peripheral ICC (PICC) or hilar ICC (HICC). The aims of this study are to clarify clinicopathological differences between PICC and HICC and to determine useful prognostic factors for patients with ICC following aggressive surgical resection.     

Serial computed tomographic evaluation in desquamative interstitial pneumonia

BACKGROUND: Desquamative interstitial pneumonia (DIP) may represent the early stage and usual interstitial pneumonia (UIP) the late stage of the same disease. The purpose of this study was to evaluate the computed tomographic (CT) features of DIP, to evaluate the changes in pattern and extent of disease over time, and to determine whether the appearances of DIP on the CT scan change to those of UIP during follow up. METHODS: Sequential CT evaluation was conducted on eight patients with DIP over a mean (SD) follow up period of 3.2 (1.3) years (range 1.6-6.5). The relative extents of ground glass and honeycombing were determined from serial CT scans. Changes in the extent and appearance of the disease were examined in paired anatomically comparable CT sections. RESULTS: Common features on the CT scans of patients with DIP were a homogeneous increase in lung attenuation (n = 5), linear areas of attenuation (n = 5), relatively well preserved lung architecture (n = 5), and the presence of small cysts (n = 6). Uncommon features were architectural distortion (n = 3), and traction bronchiectasis (n = 1). In six patients with DIP with cystic spaces these did not change with time in three cases, in two they regreased, and in one patient they increased. Open lung biopsy samples from patients with DIP with many cystic lesions showed dilated alveolar ducts and bronchioles and/or pulmonary cysts, as well as numerous macrophage-filled air spaces and mild fibrosis, but no typical honeycomb cysts were seen. CONCLUSIONS: Some of the microcysts in DIP are different from the honeycomb cysts seen in UIP, and some of the cysts seen in patients with DIP resolve with time. DIP does not progress to UIP in the short term.


     

Microsurgical excision of a retro-odontoid disc hernia via a far-lateral approach: successful treatment of a rare cause of myelopathy: case report

OBJECTIVE AND IMPORTANCE: Among mass lesions causing myelopathy at the craniovertebral junction, retro-odontoid intervertebral disc hernias are very rare, with only four such cases reported in the literature. CLINICAL PRESENTATION: A 77-year-old woman with this rare condition complained of motor and sensory disturbances in her extremities. Magnetic resonance imaging scans demonstrated an extradural mass lesion at the craniovertebral junction, compressing the lower medulla oblongata and the upper cervical cord posteriorly. INTERVENTION: The lesion, which was partly mucinous cartilaginous and partly fatty and fibrous, was meticulously removed via a left far-lateral approach. The lesion was not neoplastic but was determined to be composed of fibrocartilaginous tissue, consistent with disc material. Postoperatively, the patient's sensory disturbances and motor weakness improved, and magnetic resonance imaging scans demonstrated marked shrinkage of the lesion. CONCLUSION: Sagittal, T1-weighted, magnetic resonance imaging scans demonstrated a low-intensity band between the odontoid process and the body of the axis, which suggested a persistent cartilaginous band. Although upward migration of a herniated disc from the lower cervical spine and degeneration of retro-odontoid ligaments might be possible causes, a persistent cartilaginous band extending between the odontoid process and the body of the axis was considered to be the more likely origin of the retro-odontoid intervertebral disc hernia. Because the far-lateral surgical approach does not require retraction of the cervical cord and provides safe access to the lesion at the craniovertebral junction, it is a suitable surgical method for this condition.
