Jerusalem syndrome.

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.

Emperipolesis by megakaryocytes in patients with non-Hodgkin's lymphoma and megaloblastic anemia.

Emperipolesis, i.e. engulfment of blood cells by megakaryocytes, was observed in one patient with non-Hodgkin's lymphoma and in one patient with megaloblastic anemia. In the first patient, the engulfed cells were lymphocytes, whereas in the second one they were granulocytes. Transmission (TEM) and scanning electron microscopic (SEM) examinations showed that blood cells tend to make a rosette-like formation around the megakaryocytes engaged in this phenomenon.

Sideroblastic anemia in an elderly patient.

A 91-year-old man had been treated for iron-deficiency anemia for four years before admission to the Geriatric Unit of the Hasharon Hospital because of cardiac insufficiency and epigastric pain. In the Unit, laboratory studies revealed, in addition to hypochromic anemia, a high level of plasma iron and a reduced iron-binding capacity. The low reticulocyte count in the peripheral blood despite hyperplasia in the bone-marrow erythrocyte series, the rapid disappearance of radioactive iron from the plasma, and the impaired erythrocytic uptake of iron were all indicative of the ineffective erythropoiesis. The findings suggested the possibility of sideroblastic anemia, and examination of bone-marrow aspirates stained for iron confirmed this diagnosis.

Lymphocyte reactivity in the aged.

Lymphocyte reactivity in cultures toward the nonspecific T and B cell mitogens, phytohemagglutinin (PHA) and pokeweed (PWM), was studied in 46 subjects in three groups: a) young healthy persons, b) elderly healthy persons, and c) hospitalized elderly patients with atherosclerotic cardiovascular disease. No statistically significant differences in the lymphocyte reactivity of young and old healthy persons toward PHA could be observed with different incubation times, mitogen concentrations, or serum sources. A significantly decreased lymphocyte response was found in elderly hospitalized patients compared to young and elderly healthy subjects. In contrast, no differences in the lymphocyte reactivity toward PWM could be found among the three groups, including a comparison between elderly healthy and elderly hospitalized persons. The results suggest that the B lymphocyte-dependent response to a B lymphocyte stimulator is more stable than is the T cell response in aged subjects.

Time zone change and major psychiatric morbidity: the results of a 6-year study in Jerusalem.

Psychiatric morbidity among foreign tourists is usually connected to external factors such as unfamiliar surroundings, language problems, and special religious experiences, as well as biological factors such as dyschronism of circadian rhythms. Long-range flights through several time zones are typically followed by symptoms of jet lag such as fatigue, severe sleep schedule disturbance, impairment of cognitive functions, and even mild depression. Jet lag is generally attributed to a conflict between external time cues and internal biological rhythms. This study examined the possible association between jet lag and psychiatric morbidity among long-distance travelers hospitalized in the Jerusalem Mental Health Center, Kfar Shaul Hospital between 1993 and 1998. This was a prospective open-label study. Patients (n = 152) were divided into two groups based on the number of time zones crossed in the flight to Israel: group I, seven time zones or more (n = 81); and group II, three time zones or less (n = 71). The direction of flight was mainly eastbound. After controlling the two groups for demographic and religious background, past psychiatric history, and diagnosis on admission (P > 0.1, Fisher's exact test), the possible association between jet lag and psychotic or major affective disorder was evaluated according to the following criteria: (1) absence of major mental problems before the flight or good remission of an existing disorder 1 year or more before flight; and (2) the appearance of psychotic or major affective syndromes during the first 7 days after landing. The number of first psychotic/major affective episodes in both groups presumed as associated with jet lag was found similar (P =.5), whereas the number of relapses conjoint with jet lag in the seven or more time zone group was significantly higher (P =.04). The results suggest that the dyschronism of circadian rhythms and jet lag possibly play a role in the exacerbation of major psychiatric disorders.
