Systemic lupus erythematosus is a connective tissue disease which can affect every organ system. Neurologic abnormalities are common, occuring in approximately half of all patients at some time during the course of their illness. But symptoms of nervous system as the sole presenting symptoms occur in less than 1% of lupus patients. In patients initially presenting with neurologic symptoms and signs, differential diagnosis is difficult and sometimes it may be misdiagnosed. Therefore extensive laboratory investigations should be carried out in all patients with unusual neurological symptoms, since early diagnosis of lupus can help in providing effective treatment. We report a patient with systemic lupus erythematosus who presented with dysarthria and dysphagia resembling multiple sclerosis.

We experienced two cases of irreducible fracture dislocation and one case of neglected dislocation of the interphalangeal joint of great toe. The cause of irreducibility of fracture dislocation were an interposition of the flexor hallucis longus tendon entrapped within undisplaced longitudinal fracture of the condyle of proximal phalanx and an entrapment of the osteochondral fragment which was avulsed from the distal insertion of lateral collateral ligament.

The tibial pilon fracture has been described as difficult fracture to manage. We have reviewed 23 cases of tibial pilon fractures from Mar. 1987 to Feb. 1993 at our hospital. 1. The fractures were classified into five types according to the system of Ovadia and Beals and the methods of treatment were divided into two groups; 9 cases were treated with Ilizarov device(Group I). 6 cases out of Group I were type 3, 4 and 5. Other methods were performed in 14 cases(Group II). 8 cases out of Group II were type 3, 4, and 5. 2. In type 3, 4 and 5 fractures, there were 86 per cent good and fair radiographic results in Group I and 63 per cent good and fair results in Group II. 3. Satisfactory results were obtained by the treatment of Ilizarov method especially in type 3, 4 and 5 fractures. The advantages of Ilizarov device were its primary reduction with ligamentotaxis, easy open reduction due to proximal and distal stabilization, minimal soft tissue injury and minimal internal fixation.

Mg2+ is an important regulator of many cardiac functions. However, regulation of intracellular Mg2+ activity in the heart is not well characterized. To assess the effect of histamine H2-receptor stimulation on intracellular Mg2+ regulation, changes in extracellular Mg2+ concentration were examined under a variety of conditions in perfused guinea pig hearts. Mg2+ in the cardiac perfusate was measured by atomic absorbance spectrophotometry. The histamine (10(-6) M induced a marked Mg2+ efflux from the heart. The H2-receptor antagonists, cimetidine (10(-5) M), ranitidine (10(-5) ND, but not a H1-receptor antagonist, diphenhydramine (3 X 10(-6) M), completely blocked the histamine-induced Mg2+ efflux. The Mg2+ efflux could also be induced by forskolin (3 X 10(-6) M), 8-Cl-cAMP (2 X 10(-4) M), permeable cAMP analogue, or dimaprit, (10(-5) M). However, the carbachol (10(-5) M) considerably decreased the efflux of Mg2+. In the presence of papaverine (10(-5) M), a phosphodiesterase inhibitor, dimaprit-induced Mg2+ efflux was potentiated. These results suggest that a significant Mg2+ efflux from perfused guinea pig heart by histamine can be induced by the histamine H2-receptor stimulation and it is suggested that cytosolic cAMP may be linked.

Background: Cesarean section under spinal anesthesia may cause anxiety and hypotension. Administration of sedative drugs after delivery can diminish these side-effects, but may increase hemodynamic instability. We evaluated the effect of the administration of 0.7 μg/kg dexmedetomidine and compared it with that of 0.03 mg/kg midazolam for usefulness of sedation of the parturient after delivery during cesarean section. Methods: After obtaining written consent and the ethics board approval, 60 parturients aged 20–43 years who underwent elective cesarean delivery under spinal anesthesia were recruited. A total of 0.5% hyperbaric bupivacaine (8–10 mg) and intrathecal fentanyl (10 μg) was given to induce anesthesia. Parturients were then randomly allocated to receive either midazolam (0.03 mg/kg; group M) or dexmedetomidine 0.7 (μg/kg; group D) after delivery. The primary outcome measure was patient satisfaction score. Secondary outcomes included vital signs; vasopressor dosage; incidence of shivering, nausea, and vomiting; incidence of bradycardia; time to sensory and motor recovery; postoperative nausea and vomiting score; and postoperative pain visual analog scale at 6, 24, and 48 h. Results: Satisfaction scores for sedation were similar between the two groups. The systolic blood pressure, heart rate, oximetry saturation, and tympanic temperature were comparable between the two groups. The predicted mean systolic blood pressure of group D was 106.3 mmHg and that of group M was 107.5 mmHg. Both groups showed comparable adverse intraoperative and postoperative outcomes. Conclusions Dexmedetomidine and midazolam showed similar hemodynamic effects and patient satisfaction in parturients under spinal anesthesia.

It is not uncommon for hemangiomas to occur in the calvarium, accounting for about 10% of the benign skull tumors. A 46-year-old man was presented with a palpable scalp mass on the left parietal region. Past medical history indicated that he had undergone cranioplasty 25 years prior due to a depressed skull fracture suffered from a traffic accident. Magnetic resonance imaging revealed mixed signal intensity mass on T1 -and T2-weighted images pushing a linear signal void lesion outward in the left parietal region. After total surgical removal along with cranioplasty, he was discharged without neurological deficits. Histological examination of the surgical specimen revealed a cavernous hemangioma. A skull hemangioma occurring at the site of a cranioplasty has not yet been reported. Therefore, authors report this case in combination with a pertinent literature review.

Neuroendocrine tumor (NET) of the colon and rectum has been reported to have a low incidence and aggressive progression; it is frequently misdiagnosed and its treatment is not well documented. Four NET cases were collected at our hospital during the previous year of a colon cancer survey. Endoscopic mucosal biopsy of the colon was done for each case and all the cases proved to be adenocarcinomas. Curative surgery was conducted after the preoperative diagnostic and staging evaluation was completed. The locations of the primary lesions of the patients were all different; cecum, ascending colon, splenic flexure colon and sigmoid colon. The disease was advanced in all cases and the first postoperative diagnosis was poorly differentiated adenocarcinoma. Immunohistochemical tests followed and all the cases were positive for chromogranin A staining. A retrospective study was then conducted.
