The analgesic and adverse effects of intrathecal methadone 5 mg, 10 mg and 20 mg were assessed and compared with intrathecal morphine 0.5 mg. The study was conducted on 38 patients who underwent total knee or hip replacement surgery. The intrathecal opioid was administered at the end of surgery and assessments began 1 h thereafter and continued for 24 h. Pain measurements, supplementary analgesia requirements, and adverse effects were recorded. Intrathecal morphine 0.5 mg provided effective and prolonged analgesia. Intrathecal methadone 5 mg, 10 mg, and 20 mg produced good analgesia of 4 h duration. Thereafter the median pain scores with intrathecal methadone were consistently higher (worse) than those with intrathecal morphine (P less than 0.05). The time to the onset of discomfort severe enough to require supplemental morphine was longer after intrathecal morphine than following methadone (15 h with morphine 0.5 mg; 6.25 h, 6.5 h and 6 h with methadone 5 mg, 10 mg, and 20 mg respectively: P less than 0.05). Central nervous system depression manifesting as respiratory depression, hypotension, and excessive drowsiness occurred in 3 of 8 patients injected with methadone 20 mg intrathecally. Generalized pruritus, nausea, vomiting, and urinary retention were common and equally distributed among the treatment groups. We conclude that both intrathecal morphine 0.5 mg and methadone 5, 10, and 20 mg provide excellent analgesia but that morphine has a more prolonged effect. Methadone 20 mg produced unacceptable side effects. Clinical evidence for rostral spread of methadone within the CSF, as indicated by facial itching and excessive drowsiness, was less apparent with 5 mg than with 10 and 20 mg. Various explanations for the observed differences between the drugs are discussed.

This paper presents a case of successful treatment of candida meningitis with miconazole. A 55-year-old woman was admitted due to high fever, vomiting and urinary incontinence on November 11, 1986. Four months prior to this episode, she had been treated for a ruptured aneurysm with neck-clipping and V-P shunt for NPH. Candida albicans was cultured from her CSF. The shunt system was immediately removed and an Ommaya's reservoir was installed for external drainage and intrathecal administrations. Combination therapy (amphotericin B and flucytosine) was initiated. However, it was discontinued after ten days because of high fever and chills after intrathecal injection of amphotericin B. Treatment with miconazole intrathecally (10-90 mg/week, total 565 mg) and intravenously (200-1200 mg/day, total 70.4 g) was begun on November 23. Clinical and CSF findings were improved soon. No side effect of miconazole was observed. After V-P shunt revision, she was discharged without neurological deficit on March 12, 1987. Reports of mycosis in central nervous system are recently increasing, especially for candidosis. Cryptococcosis is noted frequently as an opportunistic infection of AIDS. The administration of amphotericin B and flucytosine has been the main therapy for mycotic meningitis. Unfortunately, however, Amphotericin B has many toxic effects, including renal dysfunction, and flucytosine can induce the emergent resistance. Miconazole has been used to successfully treat cryptococcosis, aspergillosis or coccidiosis, and was effective in our case of candida meningitis. Few side effects have been reported with its use. The intrathecal injection of miconazole is recommended for meningitis, because the drug is taken up minimally into CSF space after intravenous administration.(ABSTRACT TRUNCATED AT 250 WORDS)

We describe five cases of headache due to spontaneous liquoral hypotension, the syndrome comprising sudden, intense and oppressive orthostatic holocranial headache. The headache improved in the recumbent position and was accompanied by nausea and sometimes vomiting. There was no history of lumbar puncture or previous trauma. CSF tension was low or negative. The CSF showed a raised protein content and increased red and white cell counts. CT scan was normal or showed a slit ventricular system. Improvement was complete three to eight weeks from onset. The treatment consisted of bed rest and oral and parenteral fluid replacement. An isotope cisternography carried out in all patients while the headache was present showed a cisternographic pattern characterized by a combination of premature elimination and failure to detect the isotope at the cerebral convexity. Scan images did not show CSF leakage at any site. This stereotyped reaction pattern suggests that CSF hyperabsorption is the most likely pathophysiological mechanism of this entity.

A 13-year-old girl with a ten-year history of lymphoblastic leukemia and several central nervous system (CNS) relapses developed a bone marrow relapse and accelerated CNS leukemia. Following treatment with CNS radiation and intravenous chemotherapy, she developed fever, pancytopenia, headache, and vomiting. Her neurological function deteriorated and she died on the 20th hospital day. Multiple CSF examinations failed to disclose either leukemic cells or organisms. Blood cultures obtained from a Broviac catheter yielded Micrococcus species. Postmortem examination showed meningoependymitis with intracellular coccal organisms. The pathology of this infection resembles intracranial Whipple's disease. Intracranial intracellular bacterial infection should be excluded in the infectious complications in the immunocompromised host.

One hundred and fifty cases of Japanese encephalitis (JE) in children below 12 years of age admitted to the Headquarters Hospital, Bellary Medical College during October, 1986 to January, 1987 were studied. The youngest child affected was 1 year old. The ratio of male to female was 2:1. Hindu patients (93.33%) were significantly more than Muslim patients (6.6%). The average duration of illness prior to hospitalisation was 4.2 days (SD +/- 1.9 days). Fever, headache and/or vomiting were common presenting symptoms at the onset of illness. Onset of illness was acute or sub-acute in 105 cases (70%). CSF examination showed pleocytosis with lymphocytic reaction and normal sugar. Japanese encephalitis virus was isolated from the brain biopsy tissue in one case and the seropositivity rate for JE was 50%. The mortality was 26% and was directly related to younger age, longer duration of illness prior to admission and deeper grade of coma at the time of admission. Moderate to severe sequalae were seen in 31 patients (28.82%). The mean duration of hospital stay was 8 days.

Fifty-nine children with Japanese encephalitis admitted in Maharaj Nakhon Chiang Mai Hospital since 1984-1985 were studied. The male to female ratio was 1.18:1. The age range was between 1 to 14 years old with 74% in the age range of 6-14 years. The symptoms included change of consciousness (100%), fever (96%), headache (76%), convulsions (59%) and vomiting (52%). The neurologic signs, namely positive meningeal signs (61%), hyperreflexia (61%), positive Babinski's sign (49%) hemiplegia (42%), papilledema (22%), and other cranial nerve palsies (23%) were seen. Abnormal respiration were found in 23% and 8% of cases had hypertension. Most children (81%) had blood leukocytosis with predominant neutrophils. The average CSF white blood cell count was 200 cells per mm. with lymphocytosis in 76 percent of the patients. The average CSF protein was higher than normal. Almost all cases had normal CSF sugar levels. The JEV antibody response, mostly primary type, Occurred in about 62 percent of cases. All children received symptomatic and supportive treatment, such as antipyretics, anticonvulsants, anticerebral edema agents, adequate respiration and nutrition and physical and occupational therapies. Associated complications were treated according to the individual's need. The mortality rate and neurological sequelae were found in 17% and 57% of cases respectively. Eighteen percent of the patients suffered severe neurological sequelae. The neurological sequelae included memory deficit (46%), mental retardation (42%), hemiplegia (34%), emotional and behavioral disturbance (24%), epilepsy (20%), motor aphasia (16%), cranial nerve palsies (16%), involuntary limb movement (8%) and blindness (2%).

The role of opioid and histaminergic system in morphine induced emesis was investigated in dogs. Morphine (25 micrograms, icv) consistently evoked emesis with an average latency of 195 +/- 29 sec which was fully accounted for by an action on the chemoreceptor trigger zone (CTZ) as its ablation rendered animals refractory to vomiting. Intraventricular pretreatment with opioid antagonist naloxone, histamine H1 antagonist mepyramine and H2 antagonists metiamide and cimetidine afforded protection to icv morphine emesis. The CSF histamine concentration was significantly raised 5 min after icv morphine administration. The results suggest that both endogenous opioid and histamine are involved in morphine emesis. Naloxone in high doses (1600 micrograms, icv) elicited emesis which was not blocked by CTZ ablation confirming our earlier report.

Among various cases of intracranial hemorrhage in the newborn caused by birth injury, posterior fossa subdural hematoma is of serious nature in many cases and often results in death after critical clinical course due to compression of the respiratory center of the medulla oblongata. We have recently experienced two cases of subdural hematoma in the posterior fossa caused by birth injury, which we successfully treated non-surgically. Herein, we report these two cases and present a sequential CT scan of each. The first case is a full-term (39 weeks gestation) male infant. Delivery was carried out spontaneously with double footling presentation. At 20 hours of age, cyanosis and convulsion occurred. CT scan was performed and revealed high density areas in the posterior fossa, quadrigeminal cistern and longitudinal cerebral fissure. Bloody CSF was discharged per lumbar puncture and glycerol was infused intravenously, but the ventricle became enlarged. At this point at 9 days of age, the infant was admitted to our hospital. While he showed poor activity on admission, hematoma was absorbed gradually and disappeared at 3 months of age by conservative treatment. Now, at 6 years and 6 months of age, the patient has no neurological deficits. The second case is a full-term (40 weeks gestation) twin female infant. Due to breech presentation, delivery was conducted per breech extraction. At three days of age, vomiting, fontanel bulging and hypotonia were observed. CT scan revealed hematoma similar to that seen in the first case, and steroid and glycerol were infused intravenously. Conservative treatment was performed in this case also, and changes shown by CT scan were almost the same as those seen in the first case. The patient has no neurological deficits at 5 years and 7 months of age. Since the introduction of CT scan, early diagnosis of a subdural hematoma in the posterior fossa has been possible. But reports of successful surgical treatment are not so frequent.(ABSTRACT TRUNCATED AT 250 WORDS)

As part of a broad phase I study of recombinant human granulocyte-macrophage colony-stimulating factor (rh GM-CSF), four patients were treated who had myelodysplastic syndrome (MDS) with excess blasts. The GM-CSF was given daily as an intravenous injection over a period of 30 min for 5 days. A total of 11 cycles were conducted. Each patient received at least two different dose levels. In three patients, three different dosages were delivered. The treatment course was interrupted by a 10-day rest period. Rh GM-CSF was well tolerated, with only minor side effects seen, which included bone discomfort at the lower back, sternum and ribs, and constitutional symptoms such as low grade fever, nausea/vomiting, and mild myalgias. Whereas no increases in platelet and reticulocyte counts were recorded, elevations of absolute neutrophil counts above 100 cells/microliters occurred in all patients. The most striking finding was, however, the development of increases in the number of circulating and bone marrow blast counts that were observed particularly when doses of greater than or equal to 500 micrograms/m2 of body surface area were administered. In line with data demonstrating in vitro induction of proliferation of leukemic blast cells by rh GM-CSF, one may take advantage of blastogenesis induced in vivo that may favor the use of a therapeutic strategy by recruiting quiescent cells into the mitotic cycle which would then represent optimum targets for a subsequent cycle-specific cytotoxic chemotherapy. Such an approach could form the basis for new clinical trials in MDS.

Subacute necrotizing encephalomyelopathy (SNE; Leigh's disease), though a defined entity in neuropathological and morphological terms, is characterized by high clinical heterogenity. SNE of infancy can be defined and diagnosed on the basis of clinical symptoms more readily than juvenile and adult forms. Four patients with SNE displayed combinations of recurrent vomiting, difficulty in swallowing, failure to thrive, impairment of ocular innervation, muscle tone regulation and central regulation of respiration. These symptoms, particularly in combination, point to a disorder of the brainstem and basal ganglia. In addition, all four patients were suffering from lactic acidosis. Other possible indicators, but not in all 4 patients, were abnormal CT brain scans, impaired nerve conduction velocity, elevated CSF protein levels and enlarged mitochondria in muscle cells. Abnormal brainstem auditory evoked potentials have proved to be one of the best criteria for early diagnosis of brainstem lesions. Enzyme assays of pyruvate degradation in cultured skin fibroblasts revealed diminished activity of the pyruvate dehydrogenase complex in one patient (52 pmol/mg protein x min; median range 313, 82-917, n: 58). This paper summarizes the findings and proposes primary and secondary criteria of assistance in establishing an initial clinical diagnosis of infantile SNE. As no common pathogenetic mechanisms have yet been recognized and no uniform diagnostic markers are yet available, the diagnosis still requires confirmation by histological examination of brain and brainstem, as was the case with all four patients presented.
