Laparoscopic Management of Adnexal Masses

Retrospective study of 121 cases of adnexal masses which were managed laparoscopically was carried out. The aim of study was to evaluate the safety and effectiveness of laparoscopic management of adnexal masses. In 120 cases, procedure was completed safely with minimum morbidity. In one case laparotomy had to be done to complete the procedure. In 76 cases cystectomy was done, 26 required salpingo-oophorectomy and 19 required only salpingectomy. Histologic evaluation revealed 30 functional cysts, 36 endometriotic cysts, 11 dermoids, 9 serous cystadenomas, 3 mucinous cystadenomas, 11 parovarian cysts, 19 cases of hydrosalpinx and 2 cases of tuberculosis.Key Words: Adnexal mass, Laparoscopy, Ovarian cyst     

Enkephalinergic involvement in substantia nigra in the modulation of hypothalamically-induced predatory attack behavior

The present study was carried out in five cats which did not attack the rats spontaneously. Predatory attack on an anaesthetized rat was elicited by electrical stimulation of lateral hypothalamus at a mean current strength of 650 microA. The attack was accompanied by minimal affective display and culminated in neck biting. Microinfusions of DAME (delta-alanine methionine enkephaline) in 500 ng dose in substantia nigra facilitated the predatory attack and there was a significant reduction in the threshold current strength for affective display as well as somatomotor components. Microinfusions of naloxone, an opioid antagonist in 1.0 microg dose when DAME effect was at its peak reversed the facilitatory effects and the threshold returned to the control levels within 10 minutes of naloxone infusion at the same locus. Microinfusions of naloxone alone in similar dosage completely blocked the predatory attack response as indicated by an increase in the threshold current strength for somatomotor as well as affective display components. The somatomotor were completely inhibited and could not be elicited even when the current strength was increased to 1000 microA. Control injections of saline in similar volumes (0.5 microl) failed to produce any response Microinfusions of naloxone in lower dose (250 ng) failed to produce any blocking effect. These findings indicate that hypothalamically elicited predatory attack is facilitated by enkephalinergic mechanisms operating at the midbrain level.     

Neurobiological correlates of panic disorder and agoraphobia

Panic Disorder and agoraphobia offer considerable diagnostic and management challenges, particularly in general practice. We describe a typical case of panic disorder in a young adult. The recent advances in our understanding of brain functions can be used to explain to a certain extent the biologic basis of panic disorder. A hypothetical model integrating current views on panic disorder and agoraphobia has been proposed. The management principles including the role of cognitive therapy and pharmacotherapy have been discussed.     

Use of pulse oximeter for determining distal perfusion in neonates &; infants with suspected vascular compromise

Conclusion The use of a pulse oximeter, which is readily available in the ICU, can be of immense benefit to determine the status of distal limb perfusion in neonates and children who are suspected of having a vascular compromise, and the pulsations cannot be appreciated due to the presence of limb edema. Limb warmth and capillary filling are the primary indicators of vascularity but may be misleading in some patients. The presence of poor quality tracings or absent tracings is a definite indicator of significant ischemia. The use of a pulse oximeter, for determination of oxygen saturation, was declared by Severinghaus and Astrup to be “arguably the most significant technologic advance ever made in monitoring the well being of patients during anaesthesia, recovery and critical care. Perhaps the use of the pulse oximeter for determination of distal perfusion can further augment the statement. Editor Note The authors are to be congratulated for their observations which are clinically relevant. However we urge them to continue their study and obtain meaningful data, with proper statistical analysis. For the time being these observations may be considered preliminary.

Reversal of hyperalgesia by transplantation in lateral hypothalamic lesioned rats

Lateral hypothalamus (LHA) plays a very important role in the modulation of nociceptive behaviour. The stimulation of LHA is known to produce analgesia of both tonic and phasic pain. The present study reports hyperalgesia induced by lateral hypothalamic lesions and the effect of fetal (gestation day 16) hypothalamic transplant on the nociceptive response to phasic thermal noxious stimulation [tail flick latency (TFL)] in LHA lesioned rats. The TFL decreased significantly (12.91 +/- 3.91 sec to 10.51+/- 1.23 sec) following LHA lesion. However, after transplantation, the TFL did not change. This is the first report of a hypothalamic transplant inducing recovery of a nociceptive response.     

Giant dentigerous cyst

Dentigerous cyst - a cyst of dental origin, though common in lower jaw is relatively uncommon in upper jaw. Here a 14 years, F, presented with huge swelling of unilateral maxilla and clinicoradiologically diagnosed as dentigerous cyst is being reported along with brief review of literature.
