Case studied Median nerve entrapment is a rare, serious complication of elbow dislocation. We report a Type 4 median nerve entrapment after elbow dislocation in a 10-year-old boy. Radiologically Matev's sign and a new radiological finding—a sclerotic tunnel at the lateral side of the olecranon—were seen.Treatment The patient was treated by excising the damaged segment and reanastomosing the nerve 13 months after the injury. 相似文献

Although tension-free techniques of hernia repair using synthetic meshes have yielded encouraging results, the best method of inguinal hernia repair is still unclear. The aim of this study was to compare the responses of inflammatory mediators and postoperative pain relief following laparoscopic total extraperitoneal (TEP) hernioplasty, open tension-free mesh hernioplasty (Lichtenstein), posterior preperitoneal mesh hernioplasty (Nyhus procedure), and Bassini procedure. Patients with primary inguinal hernia were randomized in the operating room to undergo one of these repair techniques. Group I comprised 24 patients treated by Lichtenstein procedure; Group II comprised 21 patients treated by Nyhus procedure; Group III comprised 19 patients treated by Bassini procedure; and Group IV comprised 20 patients treated by laparoscopic TEP mesh hernioplasty. Postoperative pain levels following hernia repair were compared by measuring the use of patient-controlled analgesia (PCA) during the 24 hours after surgery. Serum samples withdrawn before surgery and 48 hours after surgery were assayed for C-reactive protein (CRP) content. Patient characteristics, operating time, and operative and early complications were noted. Serum CRP levels rose markedly following Nyhus (184.5 +/- 41.6 mg/L), Lichtenstein (138.4 +/- 72.5 mg/L), and Bassini repair (137.2 +/- 55.9 mg/L) compared with that of patients who underwent TEP mesh hernioplasty (55.5 +/- 41.2 mg/L). There were also significant differences in the postoperative need for analgesics via PCA among patients undergoing Nyhus (382.9 +/- 189.1 mg), Bassini (303.2 +/- 173.7 mg), and Lichtenstein (253.9 +/- 129.3) procedures compared with 196.6 +/- 148.8 mg for the TEP mesh hernioplasty group. Patients in the Lichtenstein group also had significantly less need of analgesics than those in the Nyhus and Bassini groups. In conclusion, TEP mesh hernioplasty is less traumatic and yields less postoperative pain than the Nyhus, Lichtenstein, and Bassini procedures. 相似文献

The aim of this study was to evaluate left atrial deformations using speckle tracking echocardiography for predicting left atrial appendage (LAA) thrombus in patients with suspected cardioembolic stroke who were in normal sinus rhythm. A total of 153 ischemic stroke patients (89 males, 64 females) in sinus rhythm who were suspected of having cardioembolism were included in the study. The patients underwent conventional two‐dimensional (2D) echocardiogram and 2D speckle tracking echocardiogram of the left atrium. Left atrial peak strain (LA‐4C‐RES) and left atrial precontraction strain (LA‐4C‐PUMP) were measured. Patients were divided into 2 groups according to the presence of thrombus in the LAA in transesophageal echocardiography. Both LA‐4C‐RES and LA‐4C‐PUMP values were found to be significantly lower in patients with LAA thrombus (11.8 ± 1.4% vs. 33 ± 12%, P < 0.001 and 5.8 ± 1.3% vs. 14.2 ± 5.3%, P < 0.001, respectively). A good inverse correlation was present between LA‐4C‐RES values and LAA morphologic parameters (with LAA area: r = ?0.70, P < 0.001, with LAA length: r = ?0.60, P < 0.001), and a good positive correlation was present with LAA emptying velocity with pulse Doppler (r = 0.74, P < 0.001). The area under the receiver‐operating characteristic curve of the LA‐4C‐RES was 0.94 (0.90–0.98, P < 0.001), for the LA‐4C‐PUMP, the area was 0.92 (0.87–0.96, P < 0.001) to predict LAA thrombus. Left atrial deformation parameters measured by 2D speckle tracking method was found to predict impaired LAA functions and the presence of LAA thrombus in ischemic stroke patients with suspected cardioembolism, but who are in sinus rhythm. 相似文献

Dissection of the carotid artery can occur intracranially or extracranially, although dissections tend to affect extracranial
segments of the arteries much more commonly than intracranial segments. Carotid artery dissection (CAD) is most common in
middle-aged women. Although not completely known, the main risk factors related to carotid artery dissection are genetic and
environmental factors, traumatic events, cervical manipulation, migraine, recent infections, hyperhomocysteinemia, and hereditary
connective tissue disorders. Although some cases of bilateral internal CAD have been reported, spontaneous bilateral dissections
are rare. Prolonged hoarseness is usually due to using the voice either too much, too loudly, or improperly over an extended
period of time. Disorders leading to dysphagia may affect the oral, pharyngeal, or esophageal phases of swallowing. In this
study we report on a patient with bilateral CAD who presented to our clinic with dysphagia and hoarseness. 相似文献

One of the key factors that correlates with poor survival of patients with pancreatic cancer is the extent of hypoxic areas within the tumor tissue. The adaptation of pancreatic cancer cells to limited oxygen delivery promotes the induction of an invasive and treatment-resistant phenotype, triggering metastases at an early stage of tumor development, which resist in most cases adjuvant therapies following tumor resection. In this article, the authors summarize the evidence demonstrating the significance of hypoxia in pancreatic cancer pathogenesis and discuss the possible hypoxia-induced mechanisms underlying its aggressive nature. We then conclude with promising strategies that target hypoxia-adapted pancreatic cancer cells. 相似文献

Recently, case reports of patients with primary pulmonary hypertension (PPH) treated with sildenafil demonstrated encouraging results. The mechanism proposed is a relatively selective pulmonary vasodilation via increased levels of cGMP because of the inhibition of phosphodiesterase type 5. Two siblings with a similar medical history, severe symptoms and elevated levels of pulmonary artery pressures were diagnosed with PPH after a thorough diagnostic work-up. Both patients were treated with coumadin, sildenafil, furosemide, spironolactone and digoxin. One of the patients had no improvement during the hospital course and died two months after discharge. The other patient improved dramatically during the hospital course, and this improvement was sustained. At the three-month follow-up control, she was much improved in terms of clinical status and echocardiographic findings. 相似文献

In the past decade, the number of patients demanding rhinoplasty has increased, and this has increased the use of grafts.
Although different materials are used as grafts, cartilage is the most popular one. In secondary rhinoplasties the need for
cartilage is very frequent. The most suitable cartilage grafts are the ones extracted during primary rhinoplasty. These grafts
are disposed of after the operation and in a secondary operation, grafts are obtained from a new donor site.
In our department, the surplus cartilages obtained during primary rhinoplasties of the patients who are thought to be probable
secondary rhinoplasty candidates are stored in a postauricular pocket after their volumes are measured and marked down. In
the secondary operations the volume of the grafts are measured again and the grafts are used.
We have found out that there is no significant difference between the initial and secondary volumes of lower lateral cartilages
(3.6% of initial volume is lost), but the difference between the initial and secondary volumes of septal cartilages is significant
(6.9% of initial volume is lost), and the stored cartilages are sufficient qualitatively and quantitatively for the secondary
rhinoplasties. 相似文献

This experiment was designed to investigate whether addition of vitamin C to the solution used in tumescent technique of
liposuction might increase lipolysis and whether increased fibrosis might improve skin retraction where liposuction did not
work properly and the skin had poor retraction ability. Eighteen Sprague-Dawley rats were used in two groups. Both inguinal
fat pads of rats with their vascular structures were elevated and the right inguinal fat pad was injected with 1 cc tumescent
solution as a control and the left fat pad with a 1 cc vitamin C-tumescent solution. Histopathological examination showed
that all fat pads injected with tumescent solution had normal adipocytes. Those injected with vitamin C-tumescent were shown
to have extreme fibrosis and occasional adipocytes. 相似文献
