Posterior hip fracture-dislocation associated with posterior wall fracture of the acetabulum and ipsilateral comminuted trochanteric fracture of the femur: A case report.

Introduction And Importance: Traumatic posterior dislocation of the hip is often associated with fractures of the femoral head and posterior wall of the acetabulum. However, hip fracture-dislocation that includes the posterior wall of the acetabulum and the ipsilateral femoral trochanter is rare. There is no consensus on the bone that should be operated on first, the operative position, and the choice of implant for femoral fixation.

[Bacteria that eat human lurking in the Ariake Sea- infection].

There are currently 76 species of bacteria in the genus , which is a halophilic gram-negative bacillus, 12 of which are pathogenic in humans. It is usually known as a foodborn infectious bacterium related to gastrointestinal tract. develops muscle tissue necrosis of limb and septic shock in 1 to 3 days when infected in patients with liver injury or immune function deterioration and many die from multiple organ dysfunction.

Spaceflight affects postnatal development of the aortic wall in rats.

We investigated effect of microgravity environment during spaceflight on postnatal development of the rheological properties of the aorta in rats. The neonate rats were randomly divided at 7 days of age into the spaceflight, asynchronous ground control, and vivarium control groups (8 pups for one dam). The spaceflight group rats at 9 days of age were exposed to microgravity environment for 16 days.

Identification of 62-kDa protein as an immunogenic antigen of Vibrio vulnificus for humans.

Vibrio vulnificus infection can cause necrotizing fasciitis and sepsis and can develop within a few days despite intensive care. The mortality rate is up to 60% in vulnerable people. Most patients infected with this microbe have chronic liver disease, especially liver cirrhosis or cancer, as an underlying disease.

Distribution of virulence markers among Vibrio vulnificus isolates of clinical and environmental origin and regional characteristics in Japan.

Background: Vibrio vulnificus is an opportunistic human pathogen that is widely distributed in estuarine environments and is capable of causing necrotizing fasciitis and sepsis. In Japan, based on epidemiological research, the incidences of V. vulnificus were concentrated in Kyusyu, mainly in coastal areas of the Ariake Sea.

Simultaneous measurement of urinary total nicotine and cotinine as biomarkers of active and passive smoking among Japanese individuals.

Objectives: Measuring urinary cotinine is a popular and established method of biologically monitoring exposure to tobacco smoke. However, the lower detection limit of cotinine often impedes the evaluation of passive (second-hand) smoking and this, together with unconverted nicotine, does not reflect actual levels of exposure. Furthermore, a portion of the Japanese population might have decreased ability to metabolize nicotine.

Clinical features of Vibrio vulnificus infections in the coastal areas of the Ariake Sea, Japan.

Vibrio vulnificus infection can result in necrotizing fasciitis and sepsis and is associated with high mortality. Most patients infected with this microbe have liver dysfunction as an underlying disease. However, because of the sporadic nature of outbreaks and unidentified cases, extensive evaluation of clinical features and identification of factors affecting prognosis have not been performed.

[Rapid detection of Vibrio vulnificus using a loop-mediated isothermal amplification method].

Vibrio vulnificus is found in marine waters near the coast around the world. Infection with this gram-negative rod, via ingestion of raw seafood or via a skin wound following contact with contaminated estuarine or marine water, can cause necrotizing fasciitis and sepsis. Most of patients with Vibrio vulnificus infection have underlying liver dysfunction or diabetes mellitus.

A fatal case of necrotizing fasciitis due to bacterial translocation of Klebsiella oxytoca.

We report a 73-year-old man with hepatocellular cell carcinoma who had eruptions on and severe pain in the lower leg. Within several hours, the patient's skin lesions had progressed markedly. Magnetic resonance imaging findings were consistent with necrotizing fasciitis.

A chromogenic substrate culture plate for early identification of Vibrio vulnificus and isolation of other marine Vibrios.

Vibrio vulnificus infection can result in necrotizing fasciitis and sepsis, which have short latentcy periods and high mortality rates. Thus, an easy and quick detection method is needed to improve the outcome. To distinguish V.

Survival case of Vibrio vulnificus infection with multiple endocrine neoplasia type I.

A 35-year-old female with malabsorption syndrome who underwent a pancreatoduodenectomy for multiple endocrine adenomatosis 13 years prior was admitted to our hospital with diarrhea, general fatigue, high fever, and eruption in the lower legs. The patient had consumed raw shrimp a few days before onset and presented systemic inflammatory response syndrome at the time of hospitalization. Vibrio vulnificus was isolated from a blood culture performed before admission to the intensive care unit.

[A collective review of Vibrio vulnificus infection in Japan].

Vibrio vulnificus is found globally in marine coastal waters. Infection with this organism, via ingestion of raw shellfish or exposure to marine water, can cause necrotizing fasciitis and sepsis, which have high mortality and short latency. In Japan, many cases have been reported since 1980, mainly from hospitals in western prefectures.

Effects of space flight on the histological characteristics of the aortic depressor nerve in the adult rat: electron microscopic analysis.

The effects of microgravity on the histological characteristics of the aortic depressor nerve, which is the afferent of the aortic baroreflex arc, were determined in 10 female adult rats. The rats were assigned for nursing neonates in the Space Shuttle Columbia or in the animal facility on the ground (NASA Neurolab, STS-90), and were housed for 16 days under microgravity in space (microg, n=5) or under one force of gravity on Earth (one-g, n=5). In the Schwann cell unit in which the axons of unmyelinated fibers are surrounded by one Schwann cell, the average number of axons per unit in the microg group was 2.

Calcium dynamics and vasomotion in rat mesenteric arteries.

Smooth muscle cell calcium dynamics and diameter were measured in intact pressurized rat mesenteric artery segments during vasoconstriction and vasomotion. Arteries showed a certain norepinephrine (NE) threshold (0.3-0.

Effects of running exercise during recovery from hindlimb unloading on soleus muscle fibers and their spinal motoneurons in rats.

The effects of hindlimb unloading and recovery with or without running exercise on morphological and metabolic properties of soleus muscle fibers and their spinal motoneurons in rats were investigated. Ten-week-old rats were hindlimb suspended for 2 weeks and thereafter were rehabilitated with or without voluntary running exercise for 2 weeks. A decreased percentage of type I fibers and atrophy of all types of fibers were observed after hindlimb unloading.

Morphological characteristics of the kidney and lung in the neonatal rats observed after 16 days spaceflight.

The aim of this study is to examine the structural development in kidney and lung macroscopically which relate with cardiovascular system in rats raised in space. Twenty three nine-day old rats and six fifteen-day old rats, which were launched at these ages and nursed by their dams in the Space Shuttle Colombia for 16 days (STS-90; Neurolab). Seventeen animals of the nine-day old rats were defined as the nine-day group, and the rest was defined as the re-adaptation group, which were reared on the ground for 30 more days after landing.

Growth-related changes in cell body size and succinate dehydrogenase activity of spinal motoneurons innervating the rat soleus muscle.

Cell body sizes and oxidative enzyme (succinate dehydrogenase) activities of spinal motoneurons innervating the soleus muscle were determined in rats ranging in postnatal age from 3 to 13 weeks. The soleus motoneurons were labeled by a retrograde neuronal tracer, nuclear yellow. The mean cell body sizes of motoneurons increased from 3 to 7 weeks of age, while the mean succinate dehydrogenase activities of motoneurons decreased from 3 to 7 weeks of age.

Role of membrane potential in vasomotion of isolated pressurized rat arteries.

Vasomotion, the phenomenon of vessel diameter oscillation, regulates blood flow and resistance. The main parameters implicated in vasomotion are particularly the membrane potential and the cytosolic free calcium in smooth muscle cells. In this study, these parameters were measured in rat perfused-pressurized mesenteric artery segments.

Postnatal changes in the rheological properties of the aorta in Sprague-Dawley rats.

Postnatal changes in the rheological properties of the aortic wall were investigated in relation to morphological development of the wall in Sprague-Dawley (SD) rats at 3, 8 and 20 weeks old. The mechanical tensile characteristics of the longitudinal wall strip excised from the proximal thoracic aorta were assessed with stress-strain and stress-relaxation tests. Wall tension in the low and medium strain ranges was significantly lower in 3-week-old rats than in 8-week-old rats and in 8-week-old rats than in 20-week-old rats.
