1/65. Induced hypothermia: electrocardiographic abnormalities.hypothermia was induced intermittently in a patient to combat hyperpyrexia. The electrocardiogram taken during the hypothermic phase displayed typical abnormalities and consisted of: pronounced sinus bradycardia, marked prolongation of the Q-T interval, muscle tremor artifact, and the characteristic "Osborn wave." Spontaneous rewarming resulted in disappearance of the electrocardiographic alterations, underscoring the functional and reversible nature of the abnormalities.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/65. neuroleptic malignant syndrome due to promethazine.A 42-year-old man came to our emergency room hyperthermic (oral temperature, 42.4 degrees C), diaphoretic, and delirious. Other findings included labile blood pressure, sinus tachycardia (heart rate, 138/min), tachypnea (respiratory rate 34/min), muscle rigidity, and incontinence. Two days earlier, he had gone to a local clinic with complaints of abdominal pain, nausea, and vomiting. promethazine was prescribed, and this was the patient's only medication on admission. Laboratory studies showed leukocytosis, hypernatremia, metabolic acidosis, elevated creatinine phosphokinase level, elevated transaminase levels, azotemia, hyperkalemia, hyperphosphatemia, hypocalcemia, and myoglobulinuria. The clinical and laboratory findings were characteristic of the neuroleptic malignant syndrome, with promethazine as the offending agent.- - - - - - - - - - ranking = 5921.499114198keywords = muscle rigidity, rigidity, muscle (Clic here for more details about this article) |
3/65. The pathology of human west nile virus infection.west nile virus (WNV) was identified by immunohistochemistry (IHC) and polymerase chain reaction (PCR) as the etiologic agent in 4 encephalitis fatalities in new york city in the late summer of 1999. The fatalities occurred in persons with a mean age of 81.5 years, each of whom had underlying medical problems. Cardinal clinical manifestations included fever and profound muscle weakness. autopsy disclosed encephalitis in 2 instances and meningoencephalitis in the remaining 2. The inflammation was mostly mononuclear and formed microglial nodules and perivascular clusters in the white and gray matter. The brainstem, particularly the medulla, was involved most extensively. In 2 brains, cranial nerve roots had endoneural mononuclear inflammation. In addition, 1 person had acute pancreatitis. Based on our experience, we offer recommendations for the autopsy evaluation of suspected WNV fatalities.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
4/65. Red man syndrome during administration of prophylactic antibiotic against infective endocarditis.Red man syndrome (RMS) is the occurrence flushing, pruritus, chest pain, muscle spasm or hypotension during vancomycin infusion. It usually happens as a result of rapid infusion of the drug but may also occur after slow administration. The frequency and severity of this phenomenon diminish with repeated administration of vancomycin. A case is presented whereby RMS occurred while prophylactic antibiotic against infective endocarditis was administered.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
5/65. A case of intoxication after a bite by Latrodectus tredecimguttatus.A case of intoxication in Southern bulgaria after a bite from the venomous spider Latrodectus tredecimguttatus is reported. The development of both local (acute pain, itching erythema, paraesthesiae in the area of the bite) and general (weakness, headache, dizziness, fever, vomiting, myalgia, muscle cramps) symptoms, which passed relatively easily, is described. The clinical picture and treatment are briefly commented on.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
6/65. Cyclic neutropenia and pyomyositis: a rare cause of overwhelming sepsis.Primary pyomyositis is a pyogenic infection of skeletal muscle with abscess formation, which traditionally lacks an identifiable cause. We present a case of pyomyositis for which a cause was established. This was largely due to the fact that the patient was young and fit, enabling him to survive such overwhelming sepsis long enough for cycling of his neutrophil count to become apparent. Having had multiple abscesses drained, he was successfully treated with granulocyte colony stimulating factor and has remained well since.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
7/65. Sweet's syndrome associated with retinoic acid syndrome in a patient with promyelocytic leukemia.We report a case of Sweet's syndrome associated with retinoic acid syndrome in a patient with acute promyelocytic leukemia treated with all- trans retinoic acid (ATRA). Sweet's syndrome appeared on day 6 of ATRA therapy for promyelocytic leukemia. It was associated with a mild retinoic acid syndrome, an inflammatory syndrome occurring in 25% of patients treated with ATRA and characterized by features of capillary leakage with systemic inflammatory signs. The ATRA therapy was discontinued for 11 days and treatment with corticosteroids improved the systemic and cutaneous signs. Only 11 cases of Sweet's syndrome associated with ATRA have been previously reported in the literature, involving only the skin in eight cases, the skin and muscles in two cases, and the lung, kidney, fascia, and muscles in one case. Sweet's syndrome was followed by retinoic acid syndrome in one of these cases. The previously reported cases are reviewed, and the mechanisms of Sweet's and retinoic acid syndromes and the link between them are discussed.- - - - - - - - - - ranking = 2keywords = muscle (Clic here for more details about this article) |
8/65. Successful medical management of multifocal psoas abscess following cesarean section: report of a case and review of the literature.The psoas abscess is a rare complication in obstetric and gynaecology. Two types of psoas abscess are recognized. The primary psoas abscess is generally following haematogenous dissemination of an infectious agent and the source is usually occult. The most frequently isolated pathogen is staphylococcus aureus. On the other hand, the secondary abscess is the result of local extension of an infectious process near the psoas muscle. We report the case of a patient who develops a bacteremia from an infected cesarean section wound. The complications were thigh and psoas abscesses with left sacroiliitis. Medical management with prolonged antibiotherapy permit clinical, biological and radiological improvement. Although it required a long hospital stay, medical treatment alone was effective. More experience is required to determine which therapeutic option: medical treatment and/or surgery, is the best choice for this type of complication.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
9/65. A new acute inflammatory syndrome related to the introduction of mycophenolate mofetil in patients with Wegener's granulomatosis.Mycophenolate mofetil (MMF) is increasingly used for prevention of allograft rejection and to treat immune disorders. We report the development of an acute inflammatory syndrome in two patients with Wegener's granulomatosis after MMF was introduced, because of persistent renal and systemic disease activity despite cyclophosphamide treatment. Within 1 week both patients developed an acute inflammatory syndrome, characterized by fever, arthralgias and muscle pain. No infection could be detected and no indications for increased Wegener's activity were present. MMF was stopped resulting in a rapid and complete resolution of the syndrome. A rechallenge with 2 g of MMF in the second patient resulted in a relapse of the syndrome within 4 days. There was an association between symptoms and increased levels of mycophenolic acid (MPA) acyl glucuronide and serum interleukin-6, suggesting the induction of inflammatory cytokines by MPA acyl glucuronide as the cause of the syndrome. Therefore, special attention should be given to side effects such as fever, arthralgias and muscle pain when treating patients with Wegener's granulomatosis during the active phase. Because this side effect of MMF may also occur after solid organ transplantation and in other immune disorders, pharmacokinetic profiling of MPA and MPA acyl glucuronide is needed in future studies with MMF.- - - - - - - - - - ranking = 2keywords = muscle (Clic here for more details about this article) |
10/65. Intrathecal baclofen withdrawal: a case report and review of the literature.INTRODUCTION: Spasticity is an endpoint of a variety of neurologic disorders with upper motor neuron damage. There have been several studies demonstrating improvement in spasticity through administration of intrathecal baclofen. Withdrawal from oral baclofen has been well described. Intrathecal baclofen withdrawal has been less frequently reported. We present a case of withdrawal after intrathecal baclofen pump catheter failure. PATIENT: A 14-year-old boy presented with fevers, which were thought to be related to recent spine surgery and possible pneumonia. Eventual workup revealed evidence of intrathecal baclofen withdrawal owing to pump catheter failure. His fevers, with temperatures of up to 40 degrees C, and painful muscle spasms resolved and his clinical condition improved after pump exploration and resumption of intrathecal delivery. CONCLUSIONS: Intrathecal baclofen withdrawal can be life threatening. Prompt recognition and restoration of an adequate intrathecal baclofen dose is essential for recovery.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
