1/35. lobomycosis. Report of the eighth Colombian case and review of the literature.

    The eighth Colombian case of lobomycosis and the one hundredth in the world literature is reported here. The patient was a 38-year-old female who showed a bilobed mass on the left forearm which had appeared at the site from where a similar lesion had been excised 19 years previously. She had always lived in a rural area, located in the humid subtropical forest. The tissue reactions to the fungus as well as the fruitless attempts to culture it are described. An analysis of the relevant literature is made and suggestions for experimental animal models are given in the text.

2/35. Eosinophilic meningitis. An unusual cause of headache.

    Human parasitic infections are uncommon outside the tropical north but common in animals throughout australia. The rat lung worm, angiostrongylus cantonensis, can invade the human brain to cause a chronic meningitis with prolonged headache. This condition can be diagnosed by finding a high eosinophil count in cerebrospinal fluid (CFS), the lumbar puncture also provides symptomatic relief. The outcome is usually benign but death has been reported.

3/35. trichomonas vaginalis in a perinephric abscess. A case report.

    A patient with chronic vulvo-vaginitis due to trichomonas vaginalis, and obstructive uropathy associated with renal calculi, developed a perinephric abscess following trauma incurred in a motorcycle accident. T. vaginalis was seen on smear and cultured from the purulent drainage from the perinephric abscess. Although T. vaginalis is commonly pathogenic only to the lower genito-urinary system, the upper urinary tract may very rarely be involved by ascending infection. If this protozoan spreads to extraluminal sites the inflammatory potential is marked, as has been found in animals with experimental infection. Examination of a fresh smear of pus may be critically important in the diagnosis of closed-space infections of unknown etiology.

4/35. A study on pathogenicity of hepatitis G virus.

    AIM: To study the pathogenicity of hepatitis G virus (HGV) and observe the genesis and pathological process of hepatitis G. methods: HGV-rna in serum was detected by RT-PCR assay. The immunohistochemical assays of liver tissue were performed with HGV monocoloned antibody (McAb) expressed from the region of HGV NS5 nucleic acid sequence. The clinical and pathological data of 52 patients with hepatitis G were discussed. In animal experiment, the Chinese Rhesus monkeys were infected with the serum of a patient with HGV infection. And the dynamic changes in serology and liver histology of animals were observed. RESULTS: One hundred and fifty-four patients with HGV-rna positive were selected from 1552 patients with various kinds of hepatitis. Of 154 patients with HGV infection, 52 were infected with HGV only, which accounted for 33.8 (52/154) and 102 with positive HGV-rna were super-infected with other hepatitis viruses, which accounted for 66.2 (102/154). The clinical and pathological observation showed that the acute and chronic hepatitis could be induced by HGV. The slight abnormality of transaminases ALT and AST in serum of monkeys lasted nearly 12 months and histological results showed a series of pathological changes. CONCLUSION: HGV is a hepatotropic virus and has pathogenicty.

5/35. Ultraviolet light C in the treatment of chronic wounds with MRSA: a case study.

    The prevalence of antibiotic-resistant bacteria such as methicillin-resistant staphylococcus aureus is rapidly increasing in healthcare facilities and spreading to the community. Methicillin-resistant S. aureus colonize the skin and open wounds and can interfere with wound healing. Recent studies have shown that ultraviolet light C can kill antibiotic-resistant strains of bacteria such as methicillin-resistant S. aureus in both laboratory cultures and animal tissue. This clinical report describes the effects of ultraviolet light C on wound bioburden and closure in three people with chronic ulcers infected with methicillin-resistant S. aureus. In all three patients, ultraviolet light C treatment reduced wound bioburden and facilitated wound healing. Two patients had complete wound closure following 1 week of ultraviolet light C treatment. This case study suggests that ultraviolet light C is a promising adjunctive therapy for chronic wounds containing antibiotic-resistant bacteria such as methicillin-resistant S. aureus.

6/35. pancytopenia induced by hypothermia.

    hypothermia has been demonstrated to induce pancytopenia in animals, but whether this association exists in humans is unknown. The authors report the case of an 8-year-old girl in whom hypothermia (temperature 33 degrees C-35 degrees C) is the cause of pancytopenia. The patient developed thermoregulatory dysfunction subsequent to surgical resection of a craniopharyngioma. Her recurrent cytopenias could not be explained by any etiology except chronic hypothermia. The pancytopenia improved upon rewarming the patient to a temperature of 36 degrees C. This association between hypothermia and pancytopenia has rarely been reported in humans and may be underdiagnosed especially in cases of transient or milder presentations. The authors recommend careful hematologic monitoring of patients with thermoregulatory dysfunction.

7/35. Active "itch fibers" in chronic pruritus.

    An itch-specific neuronal pathway was recently discovered in healthy humans and animals. Here the authors report that activity in this specific pathway coincides with itch under pathophysiologic conditions in a patient with chronic pruritus. Microneurographic recordings from the symptomatic area revealed spontaneous activity in six single C-fiber afferents that had the characteristic features of "itch fibers." Itch may be caused by activity in a specific subpopulation of C-fiber afferents.

8/35. The effect of vagus nerve stimulation on migraines.

    vagus nerve stimulation (VNS) inhibits nociceptive behavior in animals. VNS might reduce pain in patients with VNS device implanted for intractable seizures. One case report described possible benefits on migraines. We contacted all patients who received VNS therapy for intractable epilepsy between 1993 and 1999 at Southern illinois University, Springfield, illinois. patients who had concomitant chronic pain were subsequently interviewed. Pain intensity before and after VNS implantation was rated by the patient as average, worst, and least and on numeric rating scale from 1 to 10. Current pain measurements were compared to preimplantation by using Global Pain Relief Rating Scale. Of 62 patients who received VNS, 27 patients were interviewed; 4 patients had common migraine, and no other chronic pain syndromes were identified. All patients with migraine reported reductions in headache frequency and numeric rating scale score for average and least headache intensity. One patient reported complete relief of headaches. Improvement was reported to start 1 to 3 months after initiation of therapy. On Global Pain Relief Rating Scale, 1 patient reported complete pain relief, 2 reported a lot of pain relief, and 1 reported slight pain relief. Concomitant antiepileptic drugs were decreased in 3 patients and slightly increased in 1. VNS might be beneficial for prophylactic therapy of migraine.

9/35. Resolution of cryptosporidiosis with probiotic treatment.

    Cryptosporidium infection is usually self limited, but can be a life threatening illness in immunocompromised patients. probiotics have been used successfully in the treatment of acute diarrhoea and they have also been shown to limit cryptosporidium parvum infection in animal models. The first case of successful resolution of prolonged cryptosporidiosis with probiotic treatment is reported.

10/35. Transient ischemic attack after electromotive drug administration for chronic non-infectious cystitis: report of two similar cases.

    Electromotive drug administration (EMDA) is a new and promising approach for the treatment of chronic non-infectious cystitis. In animal studies utilizing EMDA there was evidence for deep penetration of dyes into the muscular layers of the bladder wall. However, besides minor local irritation no systemic side effects have been reported after translation of EMDA into the clinical setting.AIMS: This article reports for the first time systemic neurological alterations after EMDA for chronic non-infectious cystitis. SUBJECTS AND methods: Two male patients, aged 72 and 78 years, respectively, were readmitted to the emergency room within few hours after EMDA showing clinical signs of transient ischemic attacks (TIA). After clinical examination, both patients were observed. RESULTS: Under overnight observation without any specific therapy the symptoms vanished completely in both patients. CONCLUSIONS: In older patients (>70 years of age) undergoing EMDA, cardiac and neurologic function should be monitored. The time of treatment during the first EMDA session should be limited to 15 or 20 min.
