Unsuspected diabetes mellitus in objective polyneuritis
Oitenta pacientes que se submeteram a consulta neurológica ambulatórial por motivos diversos (excluídas polifagia, polidipsia, poliúria e modificação na massa corporal) e nos quais o exame neurológico revelou uma polineurite foram submetidos a testes de tolerância à glicose, que resultaram anormais em 41 (todos tinham glicemia de ieium normal). A principal conclusão a que chega o autor é de que a polineurite é parte integrante do quadro geral do diabete, podendo representar uma de suas manifestações mais iniciais e eventualmente preceder a detecção da própria alteração metabólica pelo menos no que concerne às técnicas atualmente empregadas. O tratamento - limitado à dieta adequada - pode propiciar notória melhora subjetiva.Eighty consecutive neurological ambulatory patients with various symptoms are presented. All patients with a history of diabetes or alcoholism were excluded. The group was composed of 54 females and 26 males ranging in age from 16 to 67 years. Neurological examination showed at least one peripheral abnormal finding in all patients. Absence of Achilles reflexes, impairment of tactile and vibratory sensibility in the distal portions of the legs and dysesthesia were the most frequent alterations. All patients showed normal fasting blood sugar and were submitted to the oral glucose tolerance test. Some evidence of abnormal glucose tolerance was present in 41 patients (51.25% of the entire group). Thus, we suggest that polyneuritis, misinterpreted as late complication, is indeed an integral part of the syndrome of diabetes and may be its very first objective sign. In conclusion, it is assumed that all patients with evidence of objective polyneuritis should be thoroughly tested for abnormality of glucose tolerance

Harmonically Trapped Quantum Gases
We solve the problem of a Bose or Fermi gas in -dimensions trapped by mutually perpendicular harmonic oscillator potentials. From the
grand potential we derive their thermodynamic functions (internal energy,
specific heat, etc.) as well as a generalized density of states. The Bose gas
exhibits Bose-Einstein condensation at a nonzero critical temperature
if and only if , and a jump in the specific heat at if and
only if . Specific heats for both gas types precisely coincide as
functions of temperature when . The trapped system behaves like an
ideal free quantum gas in dimensions. For we recover
all known thermodynamic properties of ideal quantum gases in dimensions,
while in 3D for 1, 2 and 3 one simulates behavior reminiscent of
quantum {\it wells, wires}and{\it dots}, respectively.Comment: 14 pages including 3 figures and 3 table
