Paracetamol use, availability, and knowledge of toxicity among British and American adolescents

Paracetamol is the commonest agent employed in self poisoning, however it is not clear whether adolescents possess insight into the serious complications associated with its misuse. Using a one page questionnaire, the availability, usage, and knowledge of toxicity of paracetamol among 1147 American and British adolescents was assessed. Although 90% of all students recognised that paracetamol could kill, the great majority of students overestimated the lethal dose. In addition, while knowledge regarding side effects of paracetamol was poor the drug was widely available to, and used by, the study population. It is proposed that gross overestimation of the number of tablets required to kill, poor understanding of paracetamol side effects, and wide availability of the drug contribute to its frequent use in adolescent suicidal behaviour. The inclusion of some over-the-counter medications in school drug education programs in addition to tighter control of the availability of paracetamol may help reduce the problem of adolescent self poisoning.     

Uterine leiomyomas in the infertile patient: preoperative localization with MR imaging versus US and hysterosalpingography

Eleven women with a history of infertility and uterine leiomyomas underwent magnetic resonance (MR) imaging of the pelvis prior to myomectomy. Nine also underwent preoperative pelvic ultrasonography (US), and ten underwent hysterosalpingography. All studies were interpreted prospectively by independent observers. With each imaging modality, the location (one of 11 anatomic segments), size, and appearance of detected uterine leiomyomas were determined and compared with surgical and histologic findings. Among the nine patients who underwent both MR and US, the sensitivity (85%) and accuracy (94%) of MR imaging for abnormal segments was significantly better than that of US (sensitivity = 69%, P = .015; accuracy = 87%, P = .043). For the ten patients who underwent both MR and hysterosalpingography, the sensitivity (91%) and accuracy (96%) of MR imaging was better than that of hysterosalpingography (sensitivity = 18%, P = .0005; accuracy = 72%, P = .0005). The specificities of the three modalities did not significantly differ (100%, 97%, and 98% for MR, US, and hysterosalpingography, respectively). These data suggest that MR imaging is superior to US or hysterosalpingography for preoperatively locating uterine leiomyomas.     

Effect of Cryopreservation on Semen Sample

There are varied indications of preserving a semen sample for utilization at a later day. However, the freeze-thaw cycle is bound to impart deleterious effect on the fertilizing potential of the sample. 60 semen samples divided into three groups were preserved in this study. On subsequent thawing, after three months it was seen that the yield varied between 66% to 72%. The post thaw percent yield bears a linear relationship with the pre-freeze quality. 5 pregnancies were achieved in the study testifying the preservation of fertilizing ability of the thawed samples. Sub normal semen samples which might be otherwise acceptable in a therapeutic insemination, do not withstand freezing.Key Words: Cryopreservation, Semen     

Effect of short-term Psychiatric Intervention in Cancer Patients

A total of 50 patients undergoing cancer treatment at Malignant Disease Treatment Centre were included in the present study aimed at evaluating the psychological status of cancer patients. All patients filled a specially designed proforma and the following psychological questionnaires : General Health Questionnaire, Carroll Rating Scale for Depression, State-Trait Anxiety Inventory, PGI General Well-being Scale and Quality of Life Scale. Analysis of the results showed that 22 (44%) of the cancer patients had psychiatric disorders and this number had reduced to 12 (24%) after therapy. The difference was statistically significant. Psychiatric treatment also resulted in a statistically significant reduction in level of depression as measured by Carroll Rating Scale for depression. Short term psychiatric treatment was found to be very useful in treating psychiatric morbidity and depression in cancer patients.Key Words: Cancer, Depression, Psychiatric morbidity     

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.     

Addressing the spiritual needs of a drug user living with human immunodeficiency virus: a case study

OBJECTIVES: To describe an application of Spiritual Self-Schema Therapy (3-S) with a human immunodeficiency virus (HIV)-seropositive, injection drug-using individual. INTERVENTION: 3-S is a structured and readily administered therapy for integrating a spiritual dimension into addiction treatments for HIV-positive drug users. It posits the existence of many potential "selves," salient among which are the "addict" self and the "spiritual" self. The central strategy of 3-S is to "deactivate" the addict self and "activate" the spiritual self. Techniques to achieve this shift are discussed. RESULTS: Over the course of treatment, this patient was able to use 3-S therapy to shift her dominant sense of self from that of an addict to a spiritual person and reported that this increased feelings of hope and the sense of control. CONCLUSION: A spiritually based therapy appears to help injection drug users with HIV infection and warrants further investigation.
