1/875. 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 = injury (Clic here for more details about this article) |
2/875. 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 = 1.625keywords = injury (Clic here for more details about this article) |
3/875. Painful incarcerated hernia following a rugby union lineout.Discussion related to hernias in sport usually involves the diagnosis and treatment of chronic musculotendinous groin disruption. A case of acute trauma in an incarcerated inguinal hernia, occurring in a rugby union player during a lineout, is presented. The injury arose as a result of a change in the laws of the game.- - - - - - - - - - ranking = 0.125keywords = injury (Clic here for more details about this article) |

Atrial tamponade causing acute ischemic hepatic injury after cardiac surgery.A patient developed late cardiac tamponade after aortic valve replacement and coronary artery bypass grafting. nausea and dramatic elevations of serum aminotransferases were the initial clinical manifestations of cardiac tamponade. Severe acute ischemic hepatic injury secondary to isolated compression of both atrial cavities by two loculated thrombi was diagnosed.- - - - - - - - - - ranking = 0.625keywords = injury (Clic here for more details about this article) |
5/875. hydrochlorothiazide-induced pulmonary edema and associated immunologic changes.OBJECTIVE: To describe a patient with noncardiogenic acute pulmonary edema induced by hydrochlorothiazide and to investigate the possible involvement of an immunologic mechanism in this adverse reaction. CASE SUMMARY: A 66-year-old Hispanic woman developed acute pulmonary edema 30 minutes after the ingestion of one tablet of triamterene 75 mg/hydrochlorothiazide 50 mg. The reaction was associated with hemoconcentration; a decreased white blood cell count with a shift to a predominance of polymorphonuclear cells; decreased serum immunoglobulin (Ig) G, IgG1, and IgG4; and increased serum IgM and complement 3 concentrations. DISCUSSION: Although there have been 35 reports of cases of hydrochlorothiazide-induced pulmonary edema, the etiology of this adverse reaction remains unknown. The observations presented in this case report, along with commonalities with previously reported cases, suggest that granulocytic infiltration into the lungs and IgG deposition in alveolar membranes may play a role in hydrochlorothiazide-induced pulmonary edema. CONCLUSIONS: Noncardiogenic pulmonary edema may be an immunologically mediated rare idiosyncratic reaction to hydrochlorothiazide.- - - - - - - - - - ranking = 0.033411139664727keywords = lung (Clic here for more details about this article) |
6/875. Successful treatment of traumatic acute posterior fossa subdural hematoma: report of two cases.BACKGROUND: Acute traumatic subdural hematoma of the posterior cranial fossa after a closed-head injury, excluding those in newborns, is a very rare clinical event. Generally, the outcome is poor and the overall mortality rate is high. methods: Acute posttraumatic subdural hematomas of the posterior fossa associated with acute hydrocephalus in two patients were removed by standard suboccipital approach. Preoperatively, one patient was in a coma and the Glasgow coma Score was 9 in another. CT scans showed obliterated mesencephalic cisterns in both cases. In the former there was a complex posterior fossa lesion, i.e., combined subdural and intracerebellar hematoma. The surgical decompression was completed 3 and 11 hours after injury, respectively. Intraoperative tapping of the lateral ventricle through a burr hole in the occipital area was performed in the latter case. RESULTS: Both patients survived; one made a good recovery, (i.e., glasgow outcome scale 4 in a patient who was comatose on admission), the other did not do as well (GOS 3). CONCLUSIONS: Our experience justifies the policy of mandatory early operation in cases of traumatic acute subdural hematoma of the posterior fossa associated with poor neurologic condition, even in patients of advanced age. In patients with obliterated mesencephalic cisterns and/or complex posterior fossa lesions the same approach must be followed. These clinical and CT features are not necessarily predictors of a poor outcome.- - - - - - - - - - ranking = 0.25keywords = injury (Clic here for more details about this article) |
7/875. Post-transplant acute myeloid leukemia (PT-AML).Acute myeloid leukemia following organ transplantation (PT-AML) is a rare event with only a few published cases in the literature. We present three patients who developed AML (FAB M1, M5, M4) after renal, double lung or liver transplantation. Molecular analysis detected a t(9;11) in one patient and documented the recipient origin of AML in a second patient. All patients were treated with chemotherapy. immunosuppression was reduced to cyclosporin A (CsA) and prednisone in two patients and to prednisone alone in one patient. Two patients achieved a complete remission (CR), with a remission duration of 4.6 months in one patient, the other patient died from septicemia after 15.2 months in CR. One patient was refractory to chemotherapy and died from septicemia. This report together with the documented cases in the literature suggests that PT-AML (1) develops after a median interval of 5 years after transplantation with variable latency (range, <1-17 years); (2) is heterogeneous with respect to FAB classification; (3) shows chromosomal and molecular changes typical of therapy-related AML (t-AML: -7, 8, 11q23, inv16, t(15;17)); (4) standard chemotherapy is feasible after reduction of immunosuppression and produces a CR rate of 56% with a median remission duration of 4.6 months and an overall survival of 2.6 months; (5) the major complications are early death (25%), gram-negative septicemia, progressive disease or relapse. This review provides diagnostic and therapeutic experiences and guidelines for the management of this increasing group of post-transplant patients.- - - - - - - - - - ranking = 0.033411139664727keywords = lung (Clic here for more details about this article) |
8/875. death from hyponatremia as a result of acute water intoxication in an Army basic trainee.Several reports during the past 15 years have described hyponatremia as a result of excessive water intake by athletes during endurance races. The high rates of fluid consumption have been attributed to the desire of athletes to prevent heat injury. The military has adopted guidelines for programmed drinking to maintain performance and minimize the risk of heat casualties. As military personnel increase their fluid intake, their risk of hyponatremia as a result of water overload increases. A potentially life-threatening complication is acute water intoxication. We report the first known death of an Army basic trainee as a result of acute water intoxication. The misinterpretation of his symptoms as those of dehydration and heat injury led to continued efforts at oral hydration until catastrophic cerebral and pulmonary edema developed.- - - - - - - - - - ranking = 0.25keywords = injury (Clic here for more details about this article) |
9/875. Acute atraumatic compartment syndrome in the leg.The compartment syndrome is well recognised as occurring after trauma, but atraumatic acute compartment syndrome is less widely known. We report 3 cases in whom an acute compartment syndrome developed without major injury. early diagnosis and prompt treatment by decompressive fasciotomy is of vital importance if limb function is to be preserved and complications avoided.- - - - - - - - - - ranking = 0.125keywords = injury (Clic here for more details about this article) |
10/875. Acute pseudohepatitis in a chronic substance abuser secondary to occult seat belt injury.Causes of a massive elevation in serum aminotransferases (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) in the substance-abusing patient include viral hepatitis and drug hepatotoxicity. A patient chronically addicted to injection heroin and cocaine presented to the emergency room in a confused state and was admitted to a medical ward with an AST of 4120 U/L, ALT 3820 U/L and right upper quadrant discomfort. Investigations for viral and hepatotoxic causes for the liver dysfunction revealed only hepatitis c seropositivity. A computed tomogram of the abdomen, however, revealed a significant contusion to the right lobe of the liver consistent with traumatic injury. A motor vehicle accident, in which the patient was wearing a seat belt, and which had occurred a few days before admission and had been thought to be minor, was the cause of the liver dysfunction. Significant blunt abdominal traumatic injuries are usually managed exclusively by surgical trauma units. This case underlines the need for medical specialists to be aware of hepatic contusion injuries and to have a high index of suspicion when investigating unexplained hepatocellular dysfunction in chronic substance abusers who have been in motor vehicle accidents.- - - - - - - - - - ranking = 0.625keywords = injury (Clic here for more details about this article) |
