1/1453. Pill-induced gastric injury.Pill-induced esophageal injury is a well described clinical entity. In contrast, pill-induced gastric injury has not been well characterized. In this report, we describe two patients with acute gastric ulcers due to pill ingestion and review the available literature on pill-induced gastric injury. The first patient presented with upper gastrointestinal hemorrhage and was found to have a large gastric ulcer with multiple potassium chloride pills in the ulcer crater. The second patient presented with odynophagia and endoscopy revealed doxycycline-induced esophageal and gastric injury. To our knowledge, this is the first case report of doxycycline-induced gastric ulcer.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
2/1453. The changes in human spinal sympathetic preganglionic neurons after spinal cord injury.We have applied conventional histochemical, immunocytochemical and morphometric techniques to study the changes within the human spinal sympathetic preganglionic neurons (SPNs) after spinal cord injury. SPNs are localized within the intermediolateral nucleus (IML) of the lateral horn at the thoraco-lumbar level of the spinal cord and are the major contributors to central cardiovascular control. SPNs in different thoracic segments in the normal spinal cord were similar in soma size. SPNs in the IML were also identified using immunoreactivity to choline acetyltransferase. Soma area of SPNs was 400.7 15 microm2 and 409.9 /-22 microm2 at the upper thoracic (T3) and middle thoracic (T7) segments, respectively. In the spinal cord obtained from a person who survived for 2 weeks following a spinal cord injury at T5, we found a significant decrease in soma area of the SPNs in the segments below the site of injury: soma area of SPNs at T8 was 272.9 /-11 microm2. At T1 the soma area was 418 /-19 microm2. In the spinal cord obtained from a person who survived 23 years after cord injury at T3, the soma area of SPNs above (T1) and below (T7) the site of injury was similar (416.2 /-19 and 425.0 /-20 microm2 respectively). The findings demonstrate that the SPNs in spinal segments caudal to the level of the lesion undergo a significant decrease of their size 2 weeks after spinal cord injury resulting in complete transection of the spinal cord. The impaired cardiovascular control after spinal cord injury may be accounted for, in part, by the described changes of the SPNs. The SPNs in spinal segments caudal to the injury were of normal size in the case studied 23 years after the injury, suggesting that the atrophy observed at 2 weeks is transient. More studies are necessary to establish the precise time course of these morphological changes in the spinal preganglionic neurons.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
3/1453. Thoracic disc herniation mimicking acute lumbar disc disease.STUDY DESIGN: Case report of a 49-year-old woman with a lower thoracic disc herniation mimicking acute lumbosacral radiculopathy. OBJECTIVE: To describe an unusual case of thoracic disc herniation mimicking acute lumbar disc disease. SUMMARY OF BACKGROUND DATA: Symptomatic thoracic disc herniation is rare and its clinical manifestations differ widely from those of cervical and lumbar disc herniations. Midline back pain and signs of spinal cord compression progressing over months or years are the predominant clinical features. Acute and subacute thoracic disc herniation occurs in less than 10% of patients, and isolated root pain is unusual. methods: A 49-year-old woman had acute low back pain radiation into the left buttock and the lateral aspect of the left leg and left foot. magnetic resonance imaging study showed a bulging disc and posterior osteophytes at T11-T12. RESULTS: Surgical removal of the herniated disc and osteophytes rapidly relieved her symptoms and neurologic deficits. A follow-up neurologic examination 3 years later showed normal motor and sensory functions, although low back soreness was noted occasionally. CONCLUSION: A case of thoracic disc herniation mimicking an acute lumbosacral radiculopathy is presented. Compression of the lumbosacral spinal nerve roots at the lower thoracic level after exit from the lumbar enlargement may be the mechanism for this unusual presentation.- - - - - - - - - - ranking = 20.098905338679keywords = back pain, back (Clic here for more details about this article) |
4/1453. A case of acute phlegmonous gastritis successfully treated with antibiotics.Acute phlegmonous gastritis is a rare disorder in which bacterial infection occurs in the gastric wall. gastrectomy involving the affected area has been thought to be an effective form of treatment. The authors report a case of a 32-year-old woman who had severe upper abdominal pain without signs of peritoneal irritation. endoscopy showed edematous and reddened gastric mucosa with a mass lesion in the gastric antrum. Endoscopic ultrasonography showed thickening of the antral wall and a low-echoic mass in the gastric antrum, thought to represent a fluid collection. White pus was aspirated from the mass. Localized type of acute phlegmonous gastritis with a gastric abscess was diagnosed. culture of the pus showed streptococcus pneumoniae. Through early diagnosis without laparotomy, the patient's gastritis was successfully treated with antibiotics alone.- - - - - - - - - - ranking = 144.41336079852keywords = upper abdominal pain, abdominal pain, upper (Clic here for more details about this article) |
5/1453. prognosis of acute poststreptococcal glomerulonephritis in childhood: prospective study and review of the literature.Serial, clinical, clinicopathologic and histologic studies performed simultaneously following onset of PS-AGN in children for a period of up to 144 months revealed no evidence of progression to chronic glomerulonephritis. Although acute morphologic changes were more severe in renal tissue obtained from patients with AGN following streptococcal upper respiratory infection than following pyoderma, the acute manifestations in both groups subsided 6 to 12 weeks after onset. Cumulative morphologic healing occurred in 20% of patients at 24 months, in 43% at 48 months after onset of PS-AGN; 1 patient who was unhealed at 49 months was lost to follow-up. In 2 patients (6%), acute histologic exacerbations without clinical signs occurred within 24 months after onset. Subsequent healing was documented histologically. Addis counts remained abnormal in a high percentage of patients throughout the 12 years of observation and did not correlate with the histologic findings of renal biopsy tissue. The occasional demonstration of renal vascular disease and/or hypertension may merely reflect the early development of spontaneous essential hypertension although the possibility of a relationship to the previous attack of PS-AGN is intriguing. This question cannot be answered at this time. Renal biopsy studies are more dependable than Addis counts in assessing the course of PS-AGN. The significance of persistence of immunofluorescent and/or electron microscopic changes (subepithelial dense deposits) many years after onset in 58% of 12 patients studied, at a time when a majority of patients (84%) revealed healing by light microscopy, remains to be assessed.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
6/1453. Evolution of acute cytomegalovirus gastritis to chronic gastrointestinal dysmotility in a nonimmunocompromised adult.A 30-year-old nonimmunocompromised woman developed chronic gastrointestinal dysmotility as a consequence of acute cytomegalovirus infection. The acute nature of the infection was documented by high immunoglobulin m antibody titer to cytomegalovirus (CMV); the chronicity of the infection was shown by persistence of CMV in biopsy specimens of her gastrointestinal tract over a 21/2-year period. Gastrointestinal dysmotility was confirmed by delayed emptying on gastric nuclear scintigraphy, by retrograde propagation of migrating myoelectric complexes on small intestinal manometry, and by presence of tachygastria on cutaneous electrogastrography. The patient's nausea, vomiting, abdominal pain, and early satiety resolved after a short course of treatment with leuprolide acetate but returned after medication was discontinued. Her symptoms persisted despite clearance of CMV from the gastrointestinal tract after a course of treatment with ganciclovir. These observations show that acute CMV infection can cause gastrointestinal dysmotility in nonimmunocompromised individuals and that the disturbance in gastrointestinal motor function may persist for years after viral infection of the gastrointestinal tract has been eradicated.- - - - - - - - - - ranking = 34.922871759644keywords = abdominal pain (Clic here for more details about this article) |
7/1453. Abrupt exacerbation of acute subdural hematoma mimicking benign acute epidural hematoma on computed tomography--case report.A 75-year-old male was hit by a car, when riding a bicycle. The diagnosis of acute epidural hematoma was made based on computed tomography (CT) findings of lentiform hematoma in the left temporal region. On admission he had only moderate occipitalgia and amnesia of the accident, so conservative therapy was administered. Thirty-three hours later, he suddenly developed severe headache, vomiting, and anisocoria just after a positional change. CT revealed typical acute subdural hematoma (ASDH), which was confirmed by emergent decompressive craniectomy. He was vegetative postoperatively and died of pneumonia one month later. Emergent surgical exploration is recommended for this type of ASDH even if the symptoms are mild due to aged atrophic brain.- - - - - - - - - - ranking = 4.1225677832434keywords = headache (Clic here for more details about this article) |
8/1453. Postoperative pulmonary edema.BACKGROUND: Noncardiogenic pulmonary edema may be caused by upper airway obstruction due to laryngospasm after general anesthesia. This syndrome of "negative pressure pulmonary edema" is apparently well known among anesthesiologists but not by other medical specialists. methods: We reviewed the cases of seven patients who had acute pulmonary edema postoperatively. RESULTS: There was no evidence of fluid overload or occult cardiac disease, but upper airway obstruction was the most common etiology. Each patient responded quickly to therapy without complications. CONCLUSIONS: Of the seven patients with noncardiogenic postoperative pulmonary edema, at least three cases were associated with documented laryngospasm causing upper airway obstruction. This phenomenon has been reported infrequently in the medical literature and may be underdiagnosed. Immediate recognition and treatment of this syndrome are important. The prognosis for complete recovery is excellent.- - - - - - - - - - ranking = 3keywords = upper (Clic here for more details about this article) |
9/1453. Acute spontaneous pneumomediastinum in a child with Hodgkin's disease and pulmonary fibrosis.A case of acute spontaneous pneumomediastinum in a 13-year-old boy suffering from Hodgkin's disease and pulmonary fibrosis is reported. He was initially treated for pneumocystis carinii but his respiratory function progressively deteriorated, and fibrosis secondary to bleomycin was suspected. The day before the admission to the Pediatric intensive care Unit the patient complained of anterior thoracic pain, and a chest x-ray revealed a left-sided small spontaneous pneumothorax and pneumomediastinum. Although air leak responded initially to conservative treatment, acute tension pneumomediastinum with cardiopulmonary decompensation recurred 6 days later, while the patient was on mechanical ventilation. Treatment with urgent evacuation of the accumulated air via subxiphoid drainage, using an old but ill-defined technique, resulted in complete resolution of pneumomediastinum and significant improvement of the hemodynamic condition.- - - - - - - - - - ranking = 2.5787387475074keywords = chest (Clic here for more details about this article) |
