A five-year-old male was admitted to the hospital with generalized seizures. Enlarged lymph nodes raised the suspicion of cat-scratch disease. The diagnosis was confirmed by a positive history of a cat bite, typical histopathologic findings in the biopsy of the lymph nodes, and a positive skin test. Brain CT scan and LP were repeatedly normal. The clinical course was remarkable for recurrent episodes of status epilepticus refractory to usual anticonvulsant therapy and prolonged encephalopathy consisting of mental confusion, hemiparesis, tremor, chorea, and vomiting. All neurologic symptoms gradually resolved within nine months, without sequelae. Cat-scratch encephalopathy should be suspected in a child presenting with status epilepticus and enlarged lymph nodes. Aggressive and prolonged anticonvulsant therapy is strongly recommended.

Twenty-three patients with squamous cell carcinoma were treated with a combination chemotherapy consisting of cisplatin, vincristine, and peplomycin. Overall response rate was over 70% including complete disappearance of tumors in one patient. Peplomycin was given by continuous i.v. or s.c. infusion using a micro-infusion pump. All the patients experienced some degree of nausea, vomiting, and hair loss. Phlebitis and induration of injection sites with subsequent local pigmentation were frequently encountered. Nausea and vomiting were caused mainly by cisplatin, but more than 60% of the patients experienced transient increase of anorexia or nausea in the period of peplomycin administration. Eruption with skin excoriation or pigmentation along scratch dermatitis were seen in 5 patients. These side effects were well tolerated, and high fever which is commonly observed in one-shot therapy did not develop in any patient. Pulmonary fibrosis was also not seen. Peplomycin should be given by low-dose continuous infusion because of its low toxicity and comparable antineoplastic activity to one-shot therapy.

Ten healthy males between 18 and 33 years received 10 mg morphine sulfate intravenously, or by lumbar epidural injection at two sessions 2-4 weeks apart, in random sequence. The following observations were made at intervals for 22 h. (1) Segmental hypalgesia to ice and pin scratch. (2) Cold pressor response test in hand and foot as an index of analgesia. (3) Time of onset and duration of side effects. (4) Serum concentrations of morphine. Few non-respiratory changes were seen after intravenous morphine. Cold pressor response was unchanged in hand and foot, no segmental hypalgesia or itching occurred, and only one subject complained of nausea. Marked changes occurred after epidural morphine. Cutaneous hypalgesia to ice and pin scratch appeared in the thoracolumbar region all subjects. In six subjects hypalgesia rose to the midthoracic region during the second or third hour and to the trigeminal distribution between the sixth and ninth hour in five subjects. Cold pressor response fell rapidly in the foot during the first 1.5 h after epidural morphine, and a little later cold pressor response also fell in the hand in all subjects, and remained depressed for the duration of the experimental period. Pruritus occurred at three hours in nine of the 10 subjects, nausea at about four hours in six of the subjects, and vomiting at about six hours in five of the subjects. Hypalgesia and side effects were not related to serum concentrations of morphine. These results suggest that lumbar epidural morphine travels cephalad in the cerebrospinal fluid to reach the brain stem and fourth ventricle by the sixth hour.

Ten healthy young male volunteers received in random sequence 10 mg of morphine sulfate intravenously and by lumbar epidural route during two 26-hour study sessions, in order to observe the appearance and resolution of the following side effects: (a) pruritus, (b) nausea, (c) vomiting, (d) urinary dysfunction. With the exception of one subject, who experienced transient (2 hours) nausea, none of the subjects experienced any adverse side effects after the intravenous morphine. However, all subjects experienced some degree of one or more complications, starting 3 hours after the epidural administration: generalized pruritus started at 3.0 +/- 0.3 hours (nine of 10 subjects, mean +/- SD) and lasted 5.3 +/- 4.0 hours. Nausea occurred in six subjects at 4.0 +/- 0.6 hours, and lasted 3.0 +/- 2.1 hours; vomiting occurred at 6.3 +/- 2.0 hours in five of the nauseated subjects. Urinary retention of varying intensity and duration appeared in nine subjects and required pharmacologic intervention in six subjects. Serum levels of unmodified morphine were measured at various times after administration during both sessions and did not correlate with the incidence or temporal appearance of side effects. Serial evaluation of dermatomal level of hypalgesia to ice and pin scratch demonstrated a progressive spread in the rostral direction after epidural morphine; trigeminal areas were affected by 9 hours in five of the 10 subjects. The stereotyped sequence of side effects after 10 mg of morphine by the epidural route can be interpreted to reflect widespread dispersion of morphine throughout the subarachnoid and ventricular cerebrospinal fluid.

Two cases of fatal strongyloidiasis associated with diabetes mellitus and malnutrition are reported. The patients presented with repeated vomiting and upper gastrointestinal bleeding respectively. Unusual findings in these two patients included: unexplained peripheral leukocytosis, pulmonary infiltrates, gastric aspirate leukocytosis, progression of gastrointestinal symptoms and concurrent presence of adult worms, eggs, filariform and rhabditiform larvae of Strongyloides stercoralis in alimentary canal specimens. Both patients succumbed while receiving treatment with mebendazole. The present report illustrates that unexplained gastrointestinal symptoms with extensive scratch marks below the umbilicus can be important clues to early diagnosis of the disease. In addition, the various presentations of S. stercoralis infestation are discussed with reference to predisposing factors. Current trends in laboratory diagnosis and therapeutic considerations are also delineated.

A 32-year-old woman was admitted with a diagnosis of impending premature delivery. In the 37th week of pregnancy, vaginal examination was performed. After ten minutes, vomiting, whole body flushing, and cold sweat appeared suddenly. Because fetal heart rate became 60-70 beats.min-1, emergency caesarean section was scheduled. When she arrived at the operating room, blood pressure was 75/45 and heart rate was 122 beats.min-1. Five minutes later, anesthesia was induced with thiopental and vecuronium, and operation was instituted concomitantly. After the delivery, pentazocine and midazolam were administered. During the operation, premature separation of normally implanted placenta or pressed cord was not observed. Hydrocortisone was administered for circulatory collapse. Gabexate mesilate was administered for the prevention of DIC. The scratch test, performed ten days later, revealed that latex was positive but lidocaine was negative. Therefore, it was concluded that anaphylaxis induced by latex gloves caused shock after internal examination.

Delta-9-tetrahydrocannabinol (delta-9-THC) prevents cisplatin-induced emesis via cannabinoid CB(1) receptors. Whether central and/or peripheral cannabinoid CB(1) receptors account for the antiemetic action(s) of delta-9-THC remains to be investigated. The 5-hydroxytryptamine (5-HT=serotonin) precursor, 5-hydroxytryptophan (5-HTP), is an indirect 5-HT agonist and simultaneously produces the head-twitch response (a centrally mediated serotonin 5-HT(2A) receptor-induced behavior) and emesis (a serotonin 5-HT(3) receptor-induced response, mediated by both peripheral and central mechanisms) in the least shrew (Cryptotis parva). The peripheral amino acid decarboxylase inhibitor, carbidopa, prevents the conversion of 5-HTP to 5-HT in the periphery and elevates 5-HTP levels in the central nervous system (CNS). When administered i.p. alone, a 50 mg/kg dose of 5-HTP failed to induce either behaviour while its 100 mg/kg dose produced robust frequencies of both head-twitch response and emesis. Pretreatment with carbidopa (0, 10, 20 and 40 mg/kg) potentiated the ability of both doses of 5-HTP to produce the head-twitch response in a dose-dependent but bell-shaped manner, with maximal potentiation occurring at 20 mg/kg carbidopa. Carbidopa dose-dependently reduced the frequency of 5-HTP (100 mg/kg)-induced emesis, whereas the 10 mg/kg dose potentiated, and the 20 and 40 mg/kg doses suppressed the frequency of vomits produced by the 50 mg/kg dose of 5-HTP. The peripheral and/or central antiemetic action(s) of delta-9-THC (0, 1, 2.5, 5, 10 and 20 mg/kg) against 5-HTP (100 mg/kg)-induced head-twitch response and emesis were investigated in different groups of carbidopa (0, 10 and 20 mg/kg) pretreated shrews. Irrespective of carbidopa treatment, delta-9-THC attenuated the frequency of 5-HTP-induced head-twitch response in a dose-dependent manner with similar ID(50) values. Although delta-9-THC also reduced the frequency of 5-HTP-induced emesis with similar ID(50s), at the 5 mg/kg delta-9-THC dose however, 5-HTP induced significantly less vomits in the 10 and 20 mg/kg carbidopa-treated groups relative to its 0 mg/kg control group. Moreover, increasing doses of carbidopa significantly shifted the inhibitory dose-response effect of delta-9-THC in protecting shrews from 5-HTP-induced emesis to the left. Relatively, a large dose of delta-9-THC (20 mg/kg) was required to significantly reduce the number of vomits produced by direct acting serotonergic 5-HT(3) receptor agonists, serotonin and 2-methylserotonin. Low doses of delta-9-THC (0.1-1 mg/kg) nearly completely prevented 2-methylserotonin-induced, centrally mediated, head-twitch and ear-scratch responses. The results indicate that delta-9-THC probably acts pre- and postsynaptically to attenuate emesis produced by indirect and direct acting 5-HT(3) receptor agonists via both central and peripheral mechanisms. In addition, delta-9-THC prevents 5-HTP-induced head-twitch and emesis via cannabinoid CB(1) receptors since the CB(1) receptor antagonist, SR 141716A [N-piperidino-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methylpyrazole-3-carboxamide], countered the inhibitory actions of an effective dose of delta-9-THC against both behaviours.

Rat-bite fever (RBF) is a rare, systemic illness caused by infection with Streptobacillus moniliformis. RBF has a case-fatality rate of 7%-10% among untreated patients. S. moniliformis is commonly found in the nasal and oropharyngeal flora of rats. Human infection can result from a bite or scratch from an infected or colonized rat, handling of an infected rat, or ingestion of food or water contaminated with infected rat excreta. An abrupt onset of fever, myalgias, arthralgias, vomiting, and headache typically occurs within 2-10 days of exposure and is usually followed by a maculopapular rash on the extremities. This report summarizes the clinical course and exposure history of two rapidly fatal cases of RBF identified by the CDC Unexplained Deaths and Critical Illnesses (UNEX) Project in 2003. These cases underscore the importance of 1) including RBF in the differential diagnoses of acutely ill patients with reported rat exposures and 2) preventing zoonotic infections among persons with occupational or recreational exposure to rats.

Cat-scratch disease is one of several diseases known to be caused by Bartonella species. Some infections due to Bartonella resolve spontaneously without treatment with antibiotics, but in other cases the disease can be fatal without treatment. This case study reports a 7-year-old male who presented with an unexplained encephalopathy and unusual retinal findings associated with evidence supporting infection by B. henselae. The 7-year-old male presented with a 2-week history of general malaise and cervical lymphadenopathy progressing onto fever, headache, vomiting, and confusion associated with meningism. Lumbar puncture revealed a raised cerebrospinal fluid protein, low glucose, and raised white cell count. Abnormal retinal findings and raised antibodies titres to B. quintana indicated a diagnosis of cat-scratch disease. He was treated with azithromycin orally for 3 weeks and made a complete recovery.

We herein describe a 33-year-old female who recurrently exhibited urticaria accompanied by vomiting, diarrhea and dyspnea after taking red-colored food. From her history, we suspected the cochineal dye, the commonly used natural red dye in red-colored food and beverage, to be the cause of her symptoms. Oral provocation test using cochineal dye-stained red-colored boiled-fish-paste induced urticaria and respiratory symptoms. Furthermore the prick tests and the scratch tests with cochineal dye and carminic acid, the major ingredient of cochineal dye, were also positive. These results indicate that type 1 allergy to cochineal dye caused urticaria in this patient. Thereafter, she avoided the foods containing a cochineal dye and showed a complete clinical remission. Recently, the number of literatures described about increased incidence of type 1 allergy to cochineal dye. As the usage of cochineal dye is increasing in the Japanese market, we should keep in mind that cochineal dye can be a cause of urticaria in daily practice.
