Although old or recent infarcts of a cerebellar hemisphere in the territories of the posterior inferior (PICA), superior, or anterior inferior cerebellar arteries are commonplace autopsy findings, in no case have corresponding clinical symptoms been clearly identified. We have studied three cases, two clinocaopthologically and one clinicosurgically, in which an acute infarct involving only the cerebellum lay in the PICA territory distal to the branches to the medulla oblongata. The clinical manifestations consisted of rotatory dizziness intensified by motion, nausea, vomiting, imbalance, and nystagmus. In two cases, the clinical diagnosis had been a benign labyrinthine disorder. Recognition of a syndrome corresponding to cerebellar infarction in the PICA territory is important insofar as it assists in the differential diagnosis of dizziness. It becomes of crucial importance when cerebellar infarction is the prelude to cerebellar swelling and brain stem conpression leading to coma and death unless surgically relieved.

Two cases treating aneurysms of the distal PICA were reported, and 36 cases with 39 aneurysms in the literatures in Japan were reviewed concerning the distribution of aneurysms and their findings on CT. Case 1; a 68-year-old female suffered from sudden onset of severe headache and nausea. On admission, it was found she was lethargic. However, her consciousness deteriorated down to semicoma with tetraparetic condition soon after. CT revealed subarachnoid hemorrhage in the basal, quadrigeminal and supravermian cisterns and blood clots in the entire ventricle. Cerebral angiography demonstrated an aneurysm located at the distal segment of the left PICA. She was initially treated conservatively because of being in Hunt and Kosnik Grade 5, and then, 3 weeks after onset, suboccipital craniectomy was performed and the aneurysm was clipped successfully. Case 2; a 60-year-old, female, suddenly experienced severe suboccipitalgia and vomiting. CT revealed subarachnoid hemorrhage in the entire subarachnoid space and intraventricular hemorrhages in the 4th, 3rd and lateral ventricles. Subsequently cerebral angiography was performed and left VAG demonstrated an aneurysm at the left A2-A3 junction. She underwent bifrontal craniotomy and the aneurysm was clipped via the interhemispheric approach. Her postoperative course was uneventful. Postoperative left CAG showed successful clipping of the aneurysm. However, left VAG suggested an aneurysm-like shadow in the right PICA. Right BAG carried out one week later demonstrated an aneurysm at the distal segment of the right PICA. This aneurysm was then clipped successfully under suboccipital craniectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

In previous research, 750 mg/kg 2DG yielded a number of effects suggesting a postdrug nausea; and the present experiments revealed that the illness-inducing agent LiCl similarly produced taste aversion learning at 7.5 mg/kg, inhibited drinking in water-deprived animals at 30 mg/kg, depressed feeding in hungry rats at 60 mg/kg, and evoked food intake and pica at 120 mg/kg. The appearance of eating and pica at the same dosage suggested that rats may eat food as well as a nonnutritive substance as a species-specific reaction to illness and that postdrug feeding, including that observed after 2DG, is an insufficient condition for concluding that a treatment produces no internal distress. A liquid diet that reportedly ameliorates the glucoprivic feeding deficits produced by lateral hypothalamic and zona incerta lesions theoretically could produce its effects if lesions made rats more reactive to 2DG-induced malaise and if this diet were more palatable to animals experiencing internal distress. However, this liquid diet failed to facilitate food intake after LiCl, nor did it reduce the inhibited eating produced by LiCl in food-deprived subjects. Liquid diet effects in lesioned animals, therefore, may not be explained by factors related to a 2DG-induced malaise.

Frequency and severity of nausea and of vomiting during pregnancy, and of pronounced dietary cravings and aversions, were determined in a series of South African rural and urban black, Indian, coloured (European-African-Malay) and white women. Frequency of severe nausea ranged from 3.8% in rural blacks to 19.8% in white women, and of severe vomiting from 3.1% in rural blacks to 17.8% in white and Indian women. Proportions in the other groups were intermediate. Pronounced cravings, claimed by 67-84% in the various groups, included sour, savoury and sweet foods, also fruit and milk. Aversions were claimed by 45-81% of the women in the different groups with meat, fish, coffee and fatty foods, the foods most often avoided. Pica, the consumption of such substances as earth, clay, varied ethnically and regionally; frequency was high in rural and urban black women (44.0% and 38.3%), but much lower (5%) in Indian, coloured and white women.

This is a report of a hemifacial spasm associated with a cerebellar hematoma. A 60 year-old female was admitted to our hospital due to severe vertigo and nausea. On admission, the neurological examination showed drowsy conscious level, cerebellar sign dominant on the left side, and left hemifacial spasm. CT scans disclosed a large hematoma in the left cerebellar hemisphere. An angiography revealed a dominant left PICA, but showed neither vascular malformation nor aneurysm. An emergency removal of the hematoma was carried out by using suboccipital craniectomy. Three days after the surgery, the patient's left hemifacial spasm disappeared completely. She had never suffered from left hemifacial spasm prior to this cerebellar bleeding. The hemifacial spasm was thought to be due to either the compression of the left facial nerve by the PICA which had been displaced by the cerebellar hematoma, or to the fact that the nucleus of the left facial nerve might have been stimulated by the hematoma, and the hemifacial spasm might have been caused as a result of the stimulation. The total removal of the hematoma and the postoperative CSF leakage might have decompressed the facial nerve. It was considered that this might be similar to microvascular decompression.

To determine the prevalence of intestinal parasitic infections in the residents of four Italian psychiatric institutions, we examined the stool specimens collected in triplicate from 238 residents, enrolled between May 1995 and May 1996. Besides, physician and staff nurses provided data about each resident by standardized questionnaires. Parasites were detected in the fecal samples from 128 patients (53.8%). However, in the stool specimens from 106 residents only non-pathogenic protozoa were found (82.8%). Trichuris trichiura ova, Giardia lamblia cysts and trophozoites, Cryptosporidium parvum oocysts, and Balantidium coli cysts were found in the fecal samples from 22 residents (9.2%). B. hominis was the most prevalent parasite. It was detected in the fecal specimens from 97 residents (40.8%). The so-called nonpathogenic amebae were detected in the fecal specimens from 65 residents, though, at the same time, there was no evidence of Entamoeba histolytica infection. Twelve residents (5.0%) showed intestinal colonization by nonpathogenic flagellates. All the subjects with T. trichiura infection were housed in the facility of Ancona. Parasites were found in fecal samples from all the 11 residents with behavioural aberrations, but only three of those suffering from intestinal pathogen infection associated to diarrhea. Statistical analyses revealed that the presence of pathogenic parasites in fecal specimens was significantly associated with diarrhea, nausea, vomiting, abdominal pain, fever, behavioural aberrations and nonpathogenic protozoa (p < 0.01), but did not demonstrate any other significant associations between these parasites and the other variables, such as pruritus, mucus or blood in the stools and presence of fecal leukocytes. On the other hand, the presence of nonpathogenic protozoa was significantly related to aberrations such as pica, geophagia, phytophagy, coprophagy, coprophilia and pathogenic parasites (p < 0.01). Data analyses revealed that both pathogenic and nonpathogenic parasites were significantly more common in institutionalized patients than in controls. The rare presence of clinical signs and symptoms in colonized patients represents an important public health problem, since the presence of asymptomatic carriers among residents with low hygienic conditions, raises concern of transmission of parasitic infections to professional staff and other residents. Since the eradication of parasitic colonization in residential facilities is hard to reach, an effective prevention is the only measure to deal with this public health problem.

We studied clinical manifestations of sixteen patients with cerebellar infarcts diagnosed by MRI. In fourteen of them, the stroke developed abruptly with vertigo, which continued for several days. At the early stage of illness, ataxia was obscure. But after vertigo and nausea disappeared, nine cases showed truncal ataxia, while limb ataxia was found in only five. Their vertigo was rotatory and aggravated by head movement. Gaze-evoked nystagmus was observed in only 5 cases. Four patients preferred to take unilateral posture since they experienced less vertigo. The side of their lesions was the lower side of their posture. Limb ataxia was more frequent in SCA-involving cases than in SCA-non involving cases (3 out of 6 vs 2 out of 10, respectively). On the other hand, headache was more frequent in PICA-involving cases than in PICA-non-involving cases (6 out of 11 vs 1 out of 5, respectively). Ataxic gait was seen more in medial branch-involving cases than medial branch non-involving cases (5 out of 6 vs 4 out of 10, respectively). One patient died due to obstructive hydrocephalus.

The basic concepts of homeopathy are presented, including the vital force, the Law of Similars, the Law of Proving, and the Law of Potentization. The method by which the practitioner applies these laws in a clinical setting in order to choose a homeopathic remedy is described. Careful history taking and observation of the client to ascertain the etiology and location of a complaint, associated sensations, factors that aggravate or ameliorate symptoms, the emotional and mental state, general observations, and strange, rare, and peculiar symptoms are stressed. Specific remedy recommendations for the treatment of leg cramps and other pregnancy-induced discomforts, such as anemia, herpes, nausea and hyperemesis, ptyalism, and pica are included. The use of remedies to turn breech and other malpositioned babies prior to term is presented, as well as discussions on the induction of labor and homeopathic intervention for premature labors. A description of how remedies are administered, handled, and stored is included. Finally, qualifications to practice homeopathy and legal issues for midwives are discussed.

Subarachnoid haemorrhage secondary to closed head injury is rarely associated with traumatic aneurysms of the posterior circulation. We report two cases of ruptured vertebral-posterior inferior cerebellar artery (VA-PICA) pseudoaneurysms following closed head injuries. In each case, there was no associated penetrating injury or skull fracture. The first patient was kicked followed by disturbed consciousness. The computerized tomography (CT) scan on admission and cerebral angiography on the 11th day after the trauma revealed a massive subarachnoid haemorrhage (SAH) with pan-ventricular haemorrhage and an aneurysm of the right PICA near its origin. Further ruptures occurred on the 12th, 15th, and 66th day, and he died on the 69th day. The second patient complained of persistent headache and nausea following a fight on the previous day. A CT scan and angiography on the 1st day after the trauma showed posterior fossa SAH with fourth ventricular blood and a tiny protrusion of the left VA-PICA. On the 14th day, repeated angiography revealed a remarkable growth of the aneurysm, followed by the second rupture. The repair of the VA-PICA junction was urgently performed with successful exclusion of the aneurysm. To our knowledge, only eight cases of traumatic aneurysms located at the VA or the PICA near its origin have been reported. When intraventricular blood is found with massive subarachnoid blood or with posterior fossa SAH, this ominous complication should be considered. Traumatic VA-PICA pseudoaneurysms are curable by refined microsurgical techniques, if diagnosed in time.

Intestinal parasites cause significant morbidity and mortality. Diseases caused by Enterobius vermicularis, Giardia lamblia, Ancylostoma duodenale, Necator americanus, and Entamoeba histolytica occur in the United States. E. vermicularis, or pinworm, causes irritation and sleep disturbances. Diagnosis can be made using the "cellophane tape test." Treatment includes mebendazole and household sanitation. Giardia causes nausea, vomiting, malabsorption, diarrhea, and weight loss. Stool ova and parasite studies are diagnostic. Treatment includes metronidazole. Sewage treatment, proper handwashing, and consumption of bottled water can be preventive. A. duodenale and N. americanus are hookworms that cause blood loss, anemia, pica, and wasting. Finding eggs in the feces is diagnostic. Treatments include albendazole, mebendazole, pyrantel pamoate, iron supplementation, and blood transfusion. Preventive measures include wearing shoes and treating sewage. E. histolytica can cause intestinal ulcerations, bloody diarrhea, weight loss, fever, gastrointestinal obstruction, and peritonitis. Amebas can cause abscesses in the liver that may rupture into the pleural space, peritoneum, or pericardium. Stool and serologic assays, biopsy, barium studies, and liver imaging have diagnostic merit. Therapy includes luminal and tissue amebicides to attack both life-cycle stages. Metronidazole, chloroquine, and aspiration are treatments for liver abscess. Careful sanitation and use of peeled foods and bottled water are preventive.
