Paracoccidioidomycosis (PCM) is a primary pulmonary infection that often disseminates to other organs and systems. Involvement of the central nervous system (CNS) is rare and due to the fact that both clinical alertness and establishment of the diagnosis are delayed, the disease progresses causing serious problems. We report here a case of neuroparacoccidioidomycosis (NPCM), observed in a 55 year-old male, who consulted due to neurological symptoms (left hemiparesis, paresthesias, right palpebral ptosis, headache, vomiting and tonic clonic seizures) of a month duration. Upon physical examination, an ulcerated granulomatous lesion was observed in the abdomen. To confirm the diagnosis a stereotactic biopsy was taken; additionally, mycological tests from the ulcerated lesion and a bronchoalveolar lavage were performed. In the latter specimens, P. brasiliensis yeast cells were visualized and later on, the brain biopsy revealed the presence of the fungus. Treatment with itraconazole (ITZ) was initiated but clinical improvement was unremarkable; due to the fact that the patient was taking sodium valproate for seizure control, drug interactions were suspected and confirmed by absence of ITZ plasma levels. The latter medication was changed to clonazepam and after several weeks, clinical improvement began to be noticed and was accompanied by diminishing P. brasiliensis antigen and antibody titers. In the PCM endemic areas, CNS involvement should be considered more often and the efficacy of itraconazole therapy should also be taken into consideration.

The total alkaloidal fraction of Albizia inopinata leaves (FLA) was investigated for its central nervous system (CNS) effects. FLA (10 mg/kg, i.p.) significantly reduced (45%) the locomotor activity in mice. In addition, it inhibited the conditioned avoidance response behavior and induced ptosis in rats. On the other hand, FLA did not exert significant effect on catalepsy, but potentiated the haloperidol-induced catalepsy. No effect was observed on sleep induced by sodium pentobarbital or apomorphine-induced stereotypes.

We carried out the Irwin's test with some different extracts of the aerial parts of Thidax procumbens L., the leaves of Neurolaena lobata (L.) R. Br., bark and leaves of Byrsonima crassifolia (L.) Kunth. and Gliricidia sepium Jacq. Walp., and root and leaves of Petiveria alliacea L. At dosage of 1.25 g dried plant/kg weight aqueous extracts of bark and leaves of Byrsonima crassifolia (L.) Kunth. and Gliricidia sepium Jacq. Walp. demonstrated the most activity: decrease in motor activity, back tonus, reversible parpebral ptosis, catalepsy and strong hypothermia. These extracts of both plants were assayed for effects on CNS and they caused very significant reductions in spontaneous locomotor activity, exploratory behavior and rectal temperature and they increased the sodium pentobarbital-induced sleeping time.

The initial treatment for patients with colitis cystica profunda is aimed at re-education of bowel habits to avoid straining. Patients are instructed to spend the minimum time on the commode. A high-fiber diet with bulk laxatives is recommended. If fiber does not work, polyethylene glycol solutions and surface-active stool softeners such as docusate sodium are tried. Conservative therapy resolves most symptoms. Biofeedback is offered to patients who fail dietary therapy. For patients with associated rectal prolapse, an operation designed to correct the intussusception is considered. For full-thickness prolapse (procidentia) a mucosal resection (Delorme) or perineal proctectomy (Altemeier) is recommended. Surgical treatment of internal (occult) prolapse is problematic. If attempted, a resection and suture rectopexy has the most support. In the absence of procidentia, transanal excision may be used in selected patients. If other measures fail, a mucosal sleeve resection with coloanal pull-through or a diverting colostomy may be considered.

In bony defects of the cranium, bone healing may be complicated by prolapse of surrounding tissue into the defect. This tissue acts as a potential obstruction to the migration of osteogenic cells, resulting in impaired bone formation. It has been shown in previous studies that when a membrane composed of resorbable polymers (LactoSorb) is placed over a cranial bone defect, it inhibits connective tissue from entering the wound and improves the rate and quality of the bony regenerate. This study is an extension of this work and specifically evaluated the effects of differing calcium-based surface coatings on membrane-covered cranial defects in the rabbit model. In non-critical size, full-thickness defects of the mature rabbit calvarium, four differently treated LactoSorb membranes were evaluated in each animal model over a 1-year postoperative period. The surface coatings (three treated, one untreated) consisted of a base-powdered material of calcium sodium phosphate (Osteostim, EBI, NJ), which were applied by different methods (pressed, brushed, one-sided versus two-sided). Evaluation consisted of cross-sectional histologic assessment of the cranial detects determining the quantitative bony fill and the presence of residual polymer material and calcium sodium phosphate. This study produced the following findings: (1) cranial defect regeneration occurs faster with calcium-coated membranes and is complete by 3 months; (2) no difference could be seen between the different methods of calcium sodium phosphate coating; (3) the calcium sodium phosphate coatings did not inhibit resorption of the biodegradable membranes for those systems that had coatings on one side; however, systems completely covered showed delayed resorption; and (4) the calcium sodium phosphate coatings did not produce any inflammatory reactions. These findings suggest that, in addition to inhibiting connective tissue from entering the wound site, the calcium coatings on resorbable devices may have beneficial effects in selected clinical conditions, especially in conditions where faster bone regeneration is necessary.

We evaluated the effects of rat anti-mouse IL-17 neutralizing monoclonal antibody (mAb) on the development of dextran sulfate sodium (DSS)-induced colitis. Tissue samples were evaluated by standard immunohistochemical procedure. The mucosal mRNA expression of cytokines was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). In the mice treated with the anti-IL-17 mAb, the body weight was significantly lower, and anal prolapse and colon shortening were apparent. A histological analysis indicated that the anti-IL-17 mAb markedly enhanced the severity of colitis. The mucosal infiltration of CD4-positive helper T cells and CD11b-positive granulocytes-monocytes was increased in the anti-IL-17 mAb-treated mice. Treatment with the anti-IL-17 mAb increased the mucosal expression of mRNAs of tumor necrosis factor (TNF)-alpha, interferon (IFN)-gamma, IL-6, RANTES, and IP-10. Blocking of IL-17 activity in vivo using the anti-IL-17 mAb enhanced the development of DSS-colitis in mice. This suggests an inhibitory role for IL-17 in the development of DSS-colitis.

Between 1998 and 2007, 42 patients admitted to Choray hospital, Ho Chi Minh City, and to two hospitals in adjacent regions in southern Viet Nam brought the Malayan kraits (Bungarus candidus) that had been responsible for biting them. Half of the patients had been bitten while they were asleep. Fang marks and numbness were the only local features of the bites. Common signs of neurotoxic envenoming included bilateral ptosis, persistently dilated pupils, limb weakness, breathlessness, hypersalivation, dysphonia and dysphagia. Thirty patients (71.4%) required endotracheal intubation of whom all but one were mechanically ventilated. Fourteen patients (33.3%) developed hypertension, 13 (31.0%) shock, 31 (73.8%) hyponatraemia (plasma sodium concentration < 130 mEq/l) and 30 (71.4%) showed evidence of mild rhabdomyolysis (peak plasma creatine kinase concentration 1375 +/- 140 micro/l). None developed acute kidney injury. All the patients were treated with a new monospecific B. candidus antivenom. There were no fatalities. Hyponatraemia has been reported previously in victims of Chinese kraits (Bungarus multicinctus) in northern Viet Nam and rhabdomyolysis in patients envenomed by B. niger in Bangladesh. These features of envenoming pose new problems for the management of krait bite cases in South east Asia and should stimulate a search for the causative venom toxins.

Abrupt tobacco/nicotine cessation after chronic use causes various withdrawal symptoms/signs. There is evidence that dysfunction of brain dopaminergic system might be responsible for some nicotine withdrawal symptoms. The hypothesis for the present study was that different dopaminergic agonists would relieve different nicotine withdrawal signs. Adult male Sprague-Dawley rats were used. (-)-Nicotine bitartrate (9 mg/kg/day, salt content) or equimolar sodium tartrate was infused into each rat via a subcutaneous (s.c.) osmotic minipump for 7 days. To assess nicotine withdrawal signs, several somatic abstinence signs including teeth-chattering/chews, stretches/gasps, ptosis, shakes, and yawns were counted one day after removal of pumps. These signs were attenuated by the s.c. injection of 0.4 mg/kg nicotine bitartrate. Both a dopamine D(1/5) agonist (SKF81297) and a D(2/3) agonist (pramipexole) relieved abstinence signs dose-dependently but differentially. SKF81297 (0.32 mg/kg, s.c.) reduced teeth-chattering/chews but not shakes. Pramipexole (1mg/kg, s.c.) decreased both teeth-chattering/chews and shakes. A low dose of pramipexole (0.1mg/kg, s.c.) significantly increased yawns, consistent with previous studies that the stimulation of D(3) receptors induces yawning. These results indicate that a D(2)-selective agonist should be considered a candidate to relieve nicotine withdrawal symptoms.

This study was designed to assess the effect of five common anticonvulsant drugs on naloxone-precipitated withdrawal syndrome in morphine-dependent mice. Male mice (25-35 g) were made dependent by increasing doses of morphine (30-90 mg/kg). At least three doses of phenytoin, carbamazepine, sodium valproate, lamotrigine and topiramate were injected i.p. to morphine-dependent mice 45 min prior to induction of withdrawal syndrome by naloxone (5 mg/kg, i.p.). Control animals received vehicle. Number of jumpings was counted and ptosis, tremor, piloerection and diarrhea were checked in a 30 min period started just after naloxone injection. Results showed that lamotrigine, phenytoin and sodium valproate were ineffective in suppression of withdrawal syndrome while carbamazepine produced a dose-dependent reduction of jumpings. Topiramate at the maxium applied dose (100 mg/kg) significantly reduced number of naloxone-elicited jumpings. It seems that carbamazepine by inhibition of N-Methyl-D-Aspartate (NMDA) receptors and topiramate by inhibiting kainite-activated (AMPA) receptor antagonists suppress morphine withdrawal syndrome but further studies are needed to have a definite conclusion.

We report on a patient who developed corneal haze and permanent ptosis after strabismus surgery. Formaldehyde-disinfected sodium hyaluronate which was used to protect the corneal epithelium during surgery was thought to have induced keratopathy and other findings. To our knowledge, this is the first report of corneal haze formation together with ptosis secondary to formaldehyde toxicity as a complication of strabismus surgery.
