Knowledge of scientific misconduct in publication among medical students.

BACKGROUND: Publication is a central element in research dissemination and scientific misconduct in publication is relatively ignored in biomedical research. This study is to assess the knowledge of scientific misconduct in publication among private and public sector medical students. METHODS: A questionnaire-based cross-sectional study was carried in four (two public and two private) medical colleges of Karachi in 2015. After ethical approval, data were collected through convenient sampling and analyzed in SPSS 16.0. Descriptive statistics was used to summarize the data and Chi-square test was used for cross tabulation with sex, type of medical colleges, and knowledge of scientific misconduct in publication. RESULTS: A total of 592 medical students participated with mean age of 22.2 ± 1.47 years. The majority (491, 79%) of medical students had heard about the word "publication ethics," higher among public sector students than from private sector (P < 0.001). Only 78 (13.2%) reported to had published original articles, and 64 (10.8%) and 53 (9%) medical students had heard of "ICMJE authorship criteria" and "COPE," respectively. Knowledge about fabrication of data and scientific misconduct in publication was found to be statistically significant (P < 0.05) among males than female students. Statistically significant differences were also observed between public and private medical students for knowledge regarding salami slicing, ghost author, fabrication, and photomanipulation (P < 0.001) and for plagiarism (P < 0.005). Participants from public sector colleges scored significantly better in all above variables than private medical colleges except knowledge about salami slicing in which participants from latter performed significantly better than public sector students. DISCUSSION: The study demonstrates deficiencies in knowledge regarding several aspects of publication ethics among medical students of both public and private medical colleges in Karachi. There is a need to increase the awareness of research and publication ethics among students during their academic years.

FECALITH IN THE ILEUM CAUSING INTESTINAL OBSTRUCTION.

Small bowel obstruction is one of the common conditions presenting in surgical wards, however fecalith is one of the rare causes of bowel obstruction. We present here a case of 65 years old lady, who presented with sub-acute intestinal obstruction. In spite of the initial diagnosis being sigmoid volvulus, exploratory laparotomy revealed a focolith in ileum which was retrieved through an enterotomy and primary closure was done. The patient recovered uneventfully. Thus emphasizing the need of through history and workup which steer us to the correct diagnosis.

Artificial sweeteners: safe or unsafe?

Artificial sweeteners or intense sweeteners are sugar substitutes that are used as an alternative to table sugar. They are many times sweeter than natural sugar and as they contain no calories, they may be used to control weight and obesity. Extensive scientific research has demonstrated the safety of the six low-calorie sweeteners currently approved for use in foods in the U.S. and Europe (stevia, acesulfame-K, aspartame, neotame, saccharin and sucralose), if taken in acceptable quantities daily. There is some ongoing debate over whether artificial sweetener usage poses a health threat .This review article aims to cover thehealth benefits, and risks, of consuming artificial sweeteners, and discusses natural sweeteners which can be used as alternatives.

Levetiracetam Induced Increase in Creatine Phosphokinase Levels.

Levetiracetam is an antiepileptic drug used for the treatment of generalised or partial seizures, either alone or in a combination therapy. Adverse effects have been reported with its clinical use, including headache, dizziness, liver failure etc. A rare but an important adverse effect is an increase in creatine phosphokinase (CPK) levels with its use. Herein, we present a case of 43-year male, known intravenous (IV) drug abuser with a history of decompressive craniotomy. Patient presented with severe behavioural disorder for which risperidone was given. Five days later, he started having high grade fever, hyperventilation and uncontrolled generalised tonic-clonic seizures (GTCS). After initial management of seizures, levetiracetam was started in combination with topiramate for seizure control. Seizures remained subsided but CPK levels, which were normal at the start of therapy, began to rise and reached tremendous levels of 29,000 mg/dl within a span of a week. Levetiracetam, suspected as a cause of this increase CPK levels, was stopped immediately and the levels returned to baseline within one week. This report provided us with an important step in the management of seizures with levetiracetam.
