Psychiatric patient with Chilaiditi's syndrome

BACKGROUND

Chilaiditi's sign is defined as the interposition of bowels between the liver and the right diaphragm. When the patient is symptomatic due to the intestinal obstruction, the case is referred to as Chilaiditi's syndrome.

OBJECTIVE

To emphasize the importance of accurate diagnose of Chilaiditi's syndrome in patients with psychotic disturbances.

METHOD

A 46 years old male was admitted to our department suffering from a constant epigastric and right upper quadrant pain with radiation to the right shoulder. The pain started 10 hours before the admission of the patient and was accompanied with vomiting. Patient has a history of schizophrenia and intellectual disability. He was in a stimulatory situation and unable to give any information about his state of health.

RESULTS

Patient was afebrile, tachycardic and laboratory results were normal. The chest and abdomen x-ray showed the Chilaiditi's sign. With the ultrasound procedure the case of the pneumoperitoneum was excluded. A conservative treatment with IV fluid hydration, pain management, diet modification, laxatives and enemas, was used. After a week of hospitalization, the patient felt well, having proper diet and regular evacuations and at the Chilaiditi's sign was no more observed.

DISCUSSION

The etiology of the Chilaiditi's syndrome is multifactoral and it has been reported that it is associated with psychotropic medication and intellectual disability.

CONCLUSIONS

The diagnosis of the syndrome is vital in order to avoid unnecessary and dangerous surgical interventions. Only few publications of a Chilaiditi syndrome in patients with psychosis are cited in the literature.

Inclusive K(S);(0)K(S);(0) resonance production in ep collisions at HERA

Inclusive K_{S};{0}K_{S};{0} production in ep collisions at the DESY ep collider HERA was studied with the ZEUS detector using an integrated luminosity of 0.5 fb;{-1}. Enhancements in the mass spectrum were observed and are attributed to the production of f_{2}(1270)/a_{2};{0}(1320), f_{2};{'}(1525) and f_{0}(1710). Masses and widths were obtained using a fit which takes into account theoretical predictions based on SU(3) symmetry arguments, and are consistent with the Particle Data Group values. The f_{0}(1710) state, which has a mass consistent with a glueball candidate, was observed with a statistical significance of 5 standard deviations. However, if this state is the same as that seen in gammagamma-->K_{S};{0}K_{S};{0}, it is unlikely to be a pure glueball state.

M2 pore mutations convert the glycine receptor channel from being anion- to cation-selective

Three mutations in the M2 transmembrane domains of the chloride-conducting alpha1 homomeric glycine receptor (P250Delta, A251E, and T265V), which normally mediate fast inhibitory neurotransmission, produced a cation-selective channel with P(Cl)/P(Na), = 0.27 (wild-type P(Cl)/P(Na) = 25), a permeability sequence P(Cs) > P(K) > P(Na) > P(Li), an impermeability to Ca(2+), and a reduced glycine sensitivity. Outside-out patch measurements indicated reversed and accentuated rectification with extremely low mean single channel conductances of 3 pS (inward current) and 11 pS (outward current). The three inverse mutations, to those analyzed in this study, have previously been shown to make the alpha7 acetylcholine receptor channel anion-selective, indicating a common location for determinants of charge selectivity of inhibitory and excitatory ligand-gated ion channels.

Measurement of the limiting equivalent conductivities and mobilities of the most prevalent ionic species of EGTA (EGTA2- and EGTA3-) for use in electrophysiological experiments

In many experimental biological situations, chelating agents like EGTA (ethylene glycol-bis-(beta-amino-ethyl ether) N,N,N',N'-tetra-acetic acid) are commonly used to control or suppress the concentration of divalent ions like Ca2+. The evaluation of liquid junction potentials in electrophysiological measurements, and particularly in patch-clamp situations, requires information about the ions within the solution. Where there is a significant concentration of EGTA present, it is necessary to know the values of the relative mobility of at least the most predominant ionic species of EGTA in order to complete these calculations. EGTA, with four negative charges with different pKas, can therefore exist as four differently charged ions in solution (EGTA-, EGTA2-, EGTA3- and EGTA4-) or as uncharged, although between pH 5.5 and 8 it is almost exclusively EGTA2-. We have measured limiting equivalent conductivities of the most common ionic forms of EGTA (EGTA2- and EGTA3-) encountered at physiological pHs. These were 35.9 +/- 0.7 and 56 +/- 2.5 S cm2 equiv(-1) respectively. Their mobilities relative to K+ were 0.24 +/- 0.01 for EGTA2- and 0.25 +/- 0.01 for EGTA3-. Thus for typical electrophysiological solutions, the contribution of EGTA to the liquid junction potential should be small (e.g. approximately 0.4 mV).
