Thirty-four cardiac patients, treated with nifedipine (Adalat, Procardia) during a period of 1 year or more, developed slight to severe gingival epithelial hyperplasia, and five cases presented nodular overgrowth of the gingiva. In terms of histopathologic and clinical morphology, nifedipine-induced gingival hyperplasia is similar to that known to be caused by phenytoin (Dilantin). Both drugs have the ability to alter calcium metabolism. We believe that the hyperplastic condition is related to calcium imbalance.

Taphonomy of marine environments has been studied mostly from individual cases. The formation of adipocere, or “grave-wax,” is an important indicator of the postmortem interval. In the present paper, the conditions and the timing of adipoceric formation are observed in a series of 15 cadavers recovered at different times, over a period of 433 days, from the same contained environment. Initial foci of adipocere on the subcutaneous tissue of the cadavers were detected as early as 38 days from the time of immersion in cold (10–12°C) sea water. The discrepancies between our findings and previous reports on the correlation between time since death and decomposition stages in marine environments are discussed.

Imaging techniques are a powerful tool in forensic science. Medical examiners and forensic anthropologists are less versed in the finer points of radiology than radiologists; nevertheless they are required to interpret findings from imaging studies to further medico-legal investigations. The forensic investigator often should call upon the radiologist whose expertise might prove invaluable in forensic consultations. The radiologist should be aware of the importance of storing radiographs over prolonged periods of time and of efficient record keeping methods, because various legal problems may require the radiographs for additional interpretation or for their presentation in court. Some of the main issues that might be encountered in forensic radiology are discussed in this review.

Metallic pins and wires are frequently used for fixation of fractures and dislocations. Migration is one of the potential complications of such fixation methods. Usually, migration of the pins causes only minor complications, but if the device migrates to a vital cavity, serious damage and even death may ensue. The shoulder girdle is one of the areas in which pins and wires are mostly used, the humeral neck fractures being one of them. We report a case in which a Kirschner wire migrated from a subcapital humeral fracture site into the aorta and pericardium, causing sudden cardiac tamponade and death.

The state of fusion of the basilar synchondrosis as a biological age indicator was assessed in a sample of 91 cadavers of both sexes whose ages ranged between 8 and 26 years. The correlation between the degree of closure and chronological age was investigated. Although the female population sample was very small (n = 21), the data indicate a tendency of differences in age between the "open" and "closed" groups. In the male population (n = 70), no significant differences were detected between the “open” and “closed” categories; in fact, the mean age of the two groups was the same (p = 0.9). These findings indicate that the stage of fusion of the basilar synchondrosis is not a good indicator of age in male cadavers, while in females the feature could be useful when estimating age of unknown human remains, although further investigation on a larger sample is advocated.

Pectus excavatum (PE) is a congenital sternal depression. The two most popular methods of correction are the highly modified Ravitch repair (HMRR) and the Nuss procedure. Presented here is a case of PE surgical correction in a 17.5-year-old male, beginning with the Nuss technique and converting to the HMRR during surgery, due to unsatisfying results. The procedure inadvertently culminated in perforation of the heart and lungs by the inserted pectus bar, with aggravation of the damage by resuscitation efforts. This article analyzes the chain of events leading to the patient's death and reviews the literature on the subject.
