[Symptomless aspiration of a dental bur in the lower respiratory tract--a case report].

In this study, the authors review a case of a man who asymptomatically aspired a dental bur in the lower respiratory tract during dental treatment. Lack of any symptoms of foreign body aspiration erroneously suggested swallowing of the object and its passage to the stomach. This suggestion was not excluded by a control chest radiograph.

[Accidental intoxication with methotrexate--a case report].

The report presents a case of a 49-year-old man, who was accidentally intoxicated with methotrexate. The man was admitted to a nephrology ward because of generalized erythema involving the entire body, skin pruritus, face edema, fever and difficulty with breathing. On the day of admission, additional studies demonstrated a moderate degree of anemia, considerable leucopenia, thrombocytopenia and an increased level of C-reactive protein.

Experimental effect of shots caused by projectiles fired from air guns with kinetic energy below 17 J.

Pursuant to the Polish Weapons and Ammunitions Law (Legal Gazette No 53/1999 item 549 with subsequent amendments), air guns with kinetic energy of the fired projectiles below 17 J are not regarded as weapons. The aim of the study was to assess the potential effect of shots caused by projectiles of various mass and structure fired from air guns with kinetic energy below 17 J on human soft tissues. As a model of soft tissue, we used 20% gelatin blocks.

[Penetration depth of missiles fired from a pneumatic weapon with kinetic energy below 17 J, in 20% gelatine blocks as correlated with injuries found during autopsy of a 9-year-old boy].

In Poland, according to the Act About Weapons and Ammunition, an air weapon which has kinetic energy of the fired projectiles below 17 J does not require registration and can be bought even on the Internet. Sport and recreation shooting with this weapon basically have to be performed in shooting ranges, but can be also carried on outside of shooting ranges, providing "particular caution" is exercised. In this study, we presented a case of fatal shooting of a 9-year-old boy; the weapon was a Chinese pneumatic device weapon with kinetic energy of the fired projectiles below 17 J.

[Opinionating errors in forensic medicine].

The paper presents selected evident opinionating errors committed by experts in the field of forensic medicine who issued medico-legal opinions in criminal cases, aiming at determining causes of death. The authors analyze the causes of such errors and possibilities of avoiding them, as well as the impact of the said errors on the course of criminal proceedings and the legal position of the suspects or victims. The report emphasizes the potential effect of these opinions on the fate of individuals who have been found suspected or guilty based on such opinions should they be accepted by the court without verification by summoning another expert.

[Postmortem bruising].

While examining body injuries, a very important issue is to ascertain if they were made ante or postmortem. The majority of authors are of the opinion that the presence of bruises is a proof of an antemortem origin of injuries. Nevertheless, the present authors encountered more than a dozen of cases of postmortem origin of bruises, which had occurred as much as several hours after death.

[Experimental effect of a shot caused by 4.5 mm cartridges fired from a Norica Dragon air-rifle and a Walther PPK/S air-pistol].

In Poland, according to the Weapons and Ammunition Act" an air weapon which has kinetic energy of fired projectiles below 17 J does not require registration and can be bought even on the Internet. Sport and recreational shooting with this weapon does not have to be performed in a special shooting-range, but can be carried on in an open terrain providing "particular caution" is exercised. In this study we presented experimental effects of shooting pneumatic weapons (Norica Dragon air-rifle and Walther PPK/S air-pistol) which had kinetic energy of fired projectiles below 17 J.

[Tako-tsubo cardiomyopathy in a man with cerebral haemorrhage].

Background: The Tako-Tsubo syndrome is characterized by a transient left ventricular dysfunction in the absence of obstructive coronary disease, typically precipitated by severe emotional or physical stress. It is characterized by a balloon-like left ventricular appearance on angiography, ECG changes, and elevated cardiac biomarkers. We describe a case, where Tako-Tsubo cardiomyopathy was diagnosed in a patient with subarachnoid haemorrhage.

[Accidental intravenous injection of formaldehyde].

Background: Formaldehyde can be found in operating theatres where it is used for preservation of biopsied tissues. Several misuse accidents have been described previously.We present a case where formaldehyde was mistakenly injected intravenously.

Erroneous administration of vinblastine.

This case describes a series of errors which resulted in an avoidable death of the patient. Upon being presented with the 83-year-old patient and her complaints, the physician in charge attempted to prescribe Vasolastine (a complex preparation used, for example, in treatment of angiopathy, which is administered intramuscularly once a day). Unfortunately he misspelled the name of the medicine as Vinplastyna--a non-existent preparation.
