Isolated extra-cranial internal carotid artery aneurysm in a young adult with Eale's disease.
A young male patient, a known case of Eale's disease presented with a large isolated aneurysm of the extra-cranial part of internal carotid artery. Detailed investigation failed to establish the etiology of the aneurysm, and it is possible that the underlying pathology may be the same as that of Eale's disease. Eale's disease is an idiopathic vascular disease of the peripheral retina and we hypothesize that aneurysm in this patient may be associated with Eale's disease of the eye.
Barium carbonate poisoning mimicking Guillain-Barre syndrome.
Areflexic quadriplegia due to barium carbonate (rat poison) poisoning is described in two young patients. These cases very closely resembled Guillain-Barre syndrome. The various effects of barium carbonate along with the pathogenesis of hypokalaemic paralysis are highlighted.
Fertility decline in Punjab, India: parallels with historical Europe.
Two interesting features emerge from this study of fertility behaviour in Punjab. First, it brings out the common features of peasant life and demographic behaviour found in this developing-country setting and in historical Europe. As in much of Europe, marriage was regulated to adjust to the availability of land and other resources. It is interesting to note that the operation of this 'nuptiality valve' was quite consistent with a system of joint families and partible inheritance. Secondly, the findings suggest that we need to re-define what we understand to be the features of socio-economic development which are crucial for fertility decline. Fertility began to decline steadily in this part of Punjab as early as 1940, at a time when the society was overwhelmingly agrarian, illiterate, and infant mortality was high with no access to modern contraceptive technology, as in historical Europe. The onset of the decline was brought about by development interventions which stabilized fluctuations in crop yields and mortality, thus radically improving stability of people's expectations. This study also points out the inapplicability of Mamdani's theories of fertility behaviour to the people he studies.
Inhibition of mosaic virus of Vigna sinensis Endl. with four chemicals.
Four chemicals--gibberellic acid, indoleacetic acid, 2,4-6 and thiouracil were tested for their inhibitory effect against a virus disease of Vigna sinensis (cowpea). All the four chemicals inhibited the virus to a considerable extent in in vitro studies. Pre and post-inoculation treatments were equally effective in inhibiting the virus, viz. local lesion formation on Chenopodium amaranticolor leaves. The level of inhibition subsequently decreased with lower concentration of the chemicals. Seed soaking in the chemicals controlled the virus infection.
Transcatheter closure of coronary-to-pulmonary fistula by nonconventional coils in a patient with tetralogy of Fallot.
We report a case in which a coronary-to-pulmonary fistula was successfully occluded in a patient with tetralogy of Fallot by employing the cut floppy tips of coronary angioplasty guidewires using a new technique.

Occult primary adenocarcinoma causing pseudomyxoma peritonei with pleural and hepatic metastases.
Pseudomyxoma peritonei is characterized by diffuse collections of gelatinous flux resulting from implantation of malignant tumors or irritation from ruptured benign cysts. We report a patient with pseudomyxoma peritonei caused by an occult primary adenocarcinoma, who had both pleural and hepatic metastases.
