Abstract
OBJECTIVE Clozapine and risperidone were the first two antipsychotic drugs of a new class of agents for the pharmacotherapy of schizophrenia. It has been suggested that refractory schizophrenic patients who fail to respond to neither clozapine nor risperidone may respond to a combination/augmentation strategy of both medicaments. METHOD Three cases of individuals with unremittent schizophrenia treated via this combination are presented. Response was evaluated by clinical follow-up and PANSS rating scale. RESULTS Good clinical results with no noticeable adverse side effects, ascertained by a reduction from baseline scores of the Positive and Negative Syndrome Scale (PANSS) were obtained in all three patients. CONCLUSION The findings from this pilot study suggest this combination as a possible therapeutic approach for treating resistant schizophrenic patients.

Abstract
BACKGROUND Jerusalem's psychiatrists expect to encounter, as the millennium approaches, an ever-increasing number of tourists who, upon arriving in Jerusalem, may suffer psychotic decompensation. AIMS To describe the Jerusalem syndrome as a unique acute psychotic state. METHOD This analysis is based on accumulated clinical experience and phenomenological data consisting of cultural and religious perspectives. RESULTS Three main categories of the syndrome are identified and described, with special focus on the category pertaining to spontaneous manifestations, unconfounded by previous psychotic history or psychopathology. CONCLUSIONS The discrete form of the Jerusalem syndrome is related to religious excitement induced by proximity to the holy places of Jerusalem, and is indicated by seven characteristic sequential stages.

Abstract
OBJECTIVES The aim is to study the apoptotic process in a human hepatocyte model for ethanol (EtOH)-induced apoptosis. DESIGN AND METHODS Normal human primary hepatocytes (HPH) and Hep G2 cells were exposed to increasing EtOH. 6000 cells/ sample were analyzed by transmission electron microscopy. RESULTS Apoptotic cells were observed (mmol/L EtOH): 40: 6 +/-0.5%, 60:13 +/- 2% (p < 0.05), 80: 26 +/- 1% (p < 0.001) (vs. control). Two consecutive doses of 80 mmol/L for 24 h each additionally increased apoptosis 55 +/- 3% (p < 0.0001 vs. control and p < 0.001 vs. single dose). In response to this exposure, there is a stronger apoptotic activity in HPH when compared to Hep G2 (p < 0.05). CONCLUSIONS In vitro, EtOH-induced apoptosis is regulated by dose level and the frequency of exposure.

Abstract
Clozapine is an "atypical" antipsychotic agent for treating previously resistant schizophrenic patients. Its main advantages over "typical" neuroleptics are low incidence of extrapyramidal side effects and its capacity to induce therapeutic response in previously treated refractory patients. However, withdrawal from clozapine has been observed to lead to "atypical" clinical characteristics or a "rebound phenomenon," manifested in two interwoven clinical forms: (1) psychotic exacerbation, and (2) cholinergic rebound. The underlying pathophysiological mechanism of this phenomenon is postulated to be a result of cholinergic supersensitivity. In this paper, the "rebound phenomenon" will be discussed and exemplified by three case histories in which abrupt cessation of clozapine led to serious deterioration and psychotic exacerbation, and one case in which gradual titration from the drug was employed in order to preempt this hazardous occurrence.

Abstract
UNLABELLED The prognostic factors and the causes for obit occurrence in ophidian envenoming are yet not completely clear. PURPOSE To determine the prognostic factors and the most probable causes for obit occurrence in ophidian envenoming. METHODS In the State of São Paulo were notified 12,639 cases of accidents by venomous snakes from 1988 to 1993. There were 43 deaths (0.34%). The variables from the accident notification reports were compared with the promptuary notes and/or with the death records (in lethal cases). RESULTS The snake genus was classified in 11,297 accidents and in 41 from the lethal ones. Bothrops was responsible for 9,828 (87%) accidents and 28 (68.3%) deaths, Crotalus for 1,359 (12.0%) accidents and 13 deaths (31.7%) and Micrurus for 110 (1%) accidents and no death (p < 0.05). The information regarding to sex and age of the patients was available, respectively, in 12,620 and 12,527 accidents and in all lethal ones. There were 9,783 (77.5%) male patients in the accidents and 35 (81.4%) in the lethal cases (p > 0.05). Regarding to age, 15.9% of the patients and 41.8% of the ones who died were 50 years-old or more (p < 0.05). The most frequently bitten anatomic regions were: foot (42.2%), hand (20.6%), leg (17.6%), and ankle (13.1%) in the accidents, and foot (35.7%) and leg (35.7%) in the lethal cases (p < 0.05). Coagulation disorders occurred in 34 (91.9%) from 37 patients who died (those where this datum was available). The information above was not available in non lethal cases. The most common manifestations and complications implicated as possible death causes were: acute renal failure (34-79.1%), acute respiratory failure (28-65.1%), shock (18-41.9%), and sepsis (18-41.9%). Among all lethal cases but one without information, 29.4% of the patients died within the first two days after bite and 67.6% within the first 5 days. Acute respiratory failure was most common among the patients who died owing to crotalic envenoming, and sepsis was only seen in bothropic envenoming. CONCLUSION Most of the accidents and obits are caused by Bothrops; Crotalus envenoming, leg bites, and accidents in 50 year-old patients (or more) are frequently lethal; the most common complication in lethal cases is acute renal failure.

Abstract
OBJECTIVE To assess the effect on short-term diabetes outcomes of intervention with an interdisciplinary diabetes specialist team at a primary-care community health center in East Harlem, New York City. METHODS An interdisciplinary diabetes specialist team, consisting of a diabetologist, a bicultural certified diabetes nurse-educator, and a nutritionist, attended weekly clinics at a primary-care community health center in East Harlem. Emphasis was placed on communicating in the patient's primary language and providing nutritional counseling, diabetes education, and diabetes management. After 1 year, a retrospective review of medical records for patients seen by the diabetes team was performed to assess the influence of this intervention on performance of home glucose monitoring (HGM), frequency of hypoglycemia, and changes in diabetes treatment regimens. Of 70 patients referred to the diabetes team by their primary-care providers, 50 underwent follow-up for at least 6 months and were included in the statistical analysis. RESULTS Of the 50 study patients, 94% had type 2 diabetes, with a mean duration of 11.2 years. Eighty-two percent were Hispanic, and 18% were Afro-American. The mean age was 54.6 years. Microvascular complications were present in 44%, and macrovascular complications were present in 22%. HGM was done by 13 patients (26%) before and 33 patients (66%) after diabetes team intervention (P<0.001). Before intervention by the diabetes team, 14 patients (28%) were having episodes of unrecognized hypoglycemia. Unrecognized hypoglycemia resolved after intervention in all but two patients with type 1 diabetes (P<0.001). Before intervention, diabetes treatment was dietary in 6 patients, a sulfonylurea in 19, and insulin in 25; after intervention, 5 patients had dietary management of their diabetes, 14 were taking a sulfonylurea, and 31 were receiving insulin (P<0.05). CONCLUSION Providing access to an interdisciplinary diabetes specialist team at the site of primary care had a beneficial effect on short-term diabetes outcomes in inner-city Hispanic and Afro-American patients with diabetes. Providing specialty care in the primary-care setting may be one model for improving the quality and long-term outcomes of diabetes care, particularly in high-risk populations.

Abstract
Kleptomania is currently classified in psychiatric nomenclature as one of the impulse control disorders (DSM-IV, 1994). It is characterized by repeated failure to resist impulses to steal objects, not for personal use or monetary gain. The objects are therefore discarded, given away, or hoarded (ICD-10, 1992). This disorder is known since the early 18th century from the phenomenological and clinical viewpoints, yet is still debated with regard to therapeutic strategies and criminal liability. Although there are usually complications associated with the legal consequences of being caught and arrested, subjects continue to violate the law despite repeated arrests and convictions. In a 28-year old man suffering from kleptomania, years of psychodynamic psychotherapy were ineffective. Only when he was treated as suffering from an impulse control disorder or a variant of obsessive-compulsive disorder, was there significant improvement. The positive response to buspirone (5-HT1A) augmentation of fluvoxamine (SSRI) suggested that disturbed central serotonergic neurotransmission might play an important role in the pathogenesis of kleptomania. This concept is strengthened by the comorbidity of the syndrome with depression and by its compulsive traits. We stress that although kleptomaniacs cannot differentiate between right and wrong, testing shows that their sense of reality is intact, but they act under the influence of drives they cannot resist.

Abstract
PURPOSE We determined the preferred treatment of staghorn calculi. MATERIALS AND METHODS Between January 1992 and December 1994 we performed a prospective, randomized, single center study involving 50 kidneys with complete staghorn calculi: 27 renal units were treated with extracorporeal shock wave lithotripsy (ESWL) monotherapy (group 1) and 23 were treated with combined (initial) percutaneous nephrostolithotomy with ESWL (group 2). The 2 treatment groups were compared regarding stone size, grade of collecting system dilatation and urine culture at presentation. The number of treatment sessions, narcotic doses, renal colic episodes, septic complications, unplanned ancillary procedures, length of hospitalization, total treatment duration and stone-free rate at 6 months were recorded and compared. RESULTS At the conclusion of therapy the stone-free rate was significantly greater in group 2 than in group 1 (74 versus 22%, respectively, p = 0.0005). The complication rate was significantly greater in group 1, with 15 septic complications (fever greater than 38.5C for longer than 3 days) in 10 patients compared to only 2 episodes in group 2 (p = 0.007). The unplanned ancillary procedure rate was significantly greater in group 1 (8 procedures in 7 patients versus 1 procedure in group 2, p = 0.03). The overall treatment length was significantly shorter in group 2 (1 versus 6 months, p = 0.0006). There was no significant difference in the number of procedures performed with anesthesia or in the number of hospitalization days between the 2 treatment groups. CONCLUSIONS Combined percutaneous nephrostolithotomy and ESWL should be recommended as the first line treatment choice for most patients with staghorn stones.

Abstract
Cystinuria is a hereditary disorder of amino acid transport and is manifested by the development of kidney stones. In some patients the disease is caused by mutations in the SLC3A1 gene, which is located on the short arm of chromosome 2 and encodes a renal/intestinal transporter for cystine and the dibasic amino acids. In Israel cystinuria is especially common among Jews of Libyan origin. After excluding SLC3A1 as the disease-causing gene in Libyan Jewish patients, we performed a genomewide search that shows that the Libyan Jewish cystinuria gene maps to the long arm of chromosome 19. Significant linkage was obtained for seven chromosome 19 markers. A maximal LOD score of 9.22 was obtained with the marker D19S882. Multipoint data and recombination analysis placed the gene in an 8-cM interval between the markers D19S409 and D19S208. Significant linkage disequilibrium was observed for alleles of four markers, and a specific haplotype comprising the markers D19S225, D19S208, D19S220, and D19S422 was found in 11 of 17 carrier chromosomes, versus 1 of 58 Libyan Jewish noncarrier chromosomes.

Abstract
Macroprolactinomas rarely present with apoplexy. The authors describe a patient with a macroprolactinoma who presented with apoplexy and rapid progression of a third nerve palsy. The patient was managed expectantly with bromocriptine, and within 48 hours, the patient's third nerve palsy had completely resolved. The authors suggest that all patients who present with pituitary apoplexy in the presence of a pituitary tumor receive an immediate course of bromocriptine and steroid therapy until the prolactin level can be determined. Emergency surgery is indicated if visual function is abnormal and the tumor is not a prolactinoma.

Abstract
Mitomycin is used extensively for the prevention of recurrence of superficial bladder cancer. Most treatment regimens of mitomycin are long term, since this seems more effective in preventing recurrence. During treatment some patients develop cystitis of variable severity, which may lead to mucosal ulcerations and cessation of treatment. We report a case in which long-term treatment with mitomycin, following a single episode of transitional cell bladder cancer, has led to bladder fibrosis and loss of its function, without evidence of tumor recurrence.

Abstract
SummaryWe assessed hemisphere function in right-handed male chronic schizophrenic patients using dichotic listening tests. We evaluated digit, tonic and transitional tests in patients with paranoid schizophrenia (n = 8), patients with disorganized schizophrenia (n = 8) and in control subjects (n = 8). The dichotic listening analysis discriminated between paranoid and disorganized schizophrenia. In disorganized schizophrenia, functional impairment of both hemispheres was demonstrated, while in paranoid schizophrenia dysfunction was more prominent in the right hemisphere. These results indicate the possible involvement of right hemisphere dysfunction in the pathophysiology of chronic paranoid schizophrenia, in contrast to dysfunction of both hemispheres in chronic disorganized schizophrenia.
