Adverse drug reactions in the oral cavity

Several drugs may have a number of adverse reactions (ADRs) involving the oro-facial region. The dose of the drug and the time required for the reaction to take place are relevant parameters; nonetheless, ADRs mechanisms are not always known and ADRs are not always predictable since aspects other than drug pharmacodynamics and/or pharmacokinetics, as well as various interacting variables contribute to the final outcome. All tissues and many functions of the oral cavity can be affected. In particular, salivary function is frequently involved and hypo-salivation is the main manifestation; several mucosal lesions with different morphology (ulcerations, vesiculobullous lesions, white lesions, pigmentations, swelling) are also possible. Taste, sensation and trigeminal function alterations have been reported and the recent evidence regarding the occurrence of jawbones osteonecrosis, especially in bisphosphonates treated patients, is increasing. Clinical management may be quite difficult due to the multiplicity of involved classes of drugs and substances (dental materials, foods), the variety of affected tissues and functions, the type of produced lesions and disturbances, the complexity of related pathogenetic mechanisms (if known), the difficulties in assessing causality and managing drug withdrawal and/or dose adjustment, as well as in establishing specific treatments, if any. In this paper the most common and significant oral ADRs, their related aspects and importance (including medico-legal implications) for health care providers will be discussed.

Medicolegal implications of surgical errors and complications in neck surgery: A review based on the Italian current legislation

Abstract Aim of the present paper is the review of the principal complications associated to endocrine neck surgery considering how expertise, full adoption of guidelines, appropriate technology and proper informed consent may limit the medicolegal claims at the light of the incoming new regulation of the medical professional legal responsibility. A literature search, using the Medline/PubMed database for full-length papers, was used. Postoperative recurrent laryngeal nerve (RLN) palsy and hypoparathy-roidism remain the principal causes of surgical malpractice claims . In the procedure of neck lymphadenctomy intra-operative haemorrhage, thoracic duct injury, injuries to loco-regional nerves can be observed and can be source of claims. After many years of increased medicolegal litigations, the Italian government is proposing a drastic change in the regulations of supposed medical malpractice in order to guarantee the patient’s right to a safe treatment and in the meantime to defend clinicians from often unmotivated and prejudicial legal cases. Surgical errors and complications in neck surgery are a relevant clinical issue. Only the combination of surgical and clinical expertise, application of guidelines, appropriate technology and a routinely use of specific informed consent can contain potential medicolegal implications.

Early Medical Skull Surgery for Treatment of Post-Traumatic Osteomyelitis 5,000 Years Ago

Here we describe the findings of a unique example of the early techniques adopted in neurosurgery around 5000 years ago, consisting in a double well healed skull trephination associated with a post-cranial traumatic event occurring intra vitam to a young male from the Early Chalcolithic cemetery of Pontecagnano (South Italy, ca. 4,900 - 4,500 cal BP). Morphological, X-ray and 3D-CT scan skull-cap evaluation revealed that the main orifice was produced by scraping, obtained by clockwise rotary motion of a right-handed surgeon facing the patient, while the partial trephination was carried out by using a stone point as a drilling tool. In both cases, bone regrowth is indicative of the individuals prolonged postoperative survival and his near-complete recovery. The right femur shows a poorly healed mid-shaft fracture presumably induced by a high energy injury, and a resulting chronic osteomyelitis, affecting both femurs by hematogenous spread of the infection. Our observations on the visual and radiological features of skull and femur lesions, along with evidence on the timing of experimental bone regrowth vs. healing of lower limb fractures associated to long-term bone infections now suggest that this young man underwent a double skull trephination in order to alleviate his extremely painful condition induced by chronic osteomyelitis, which is thought to have been the cause of death.

Informed consent in robotic surgery: quality of information and patient perception

Abstract Introduction Obtaining a valid informed consent in the medical and surgical field is a long debated issue in the literature. In robotic surgery we believe in the necessity to follow three arrangements to make the informed consent more complete. Material and methods This study presents correlations and descriptions based on forensic medicine concepts research, literature review, and the proposal of an integration in the classic concept of informed consent. Conclusion In robotic surgery we believe in the necessity to follow three arrangements to make the IC more complete. Integrate the information already present in the informed consent with data on the surgeon’s experience in RS, the number of procedures of the department and the regional map of expertises by procedure.

Contralateral risk reducing mastectomy in Non-BRCA-Mutated patients

Abstract The use of contralateral risk reducing mastectomy (CRRM) is indicated in women affected by breast cancer, who are at high risk of developing a contralateral breast cancer, particularly women with genetic mutation of BRCA1, BRCA2 and P53. However we should consider that the genes described above account for only 20-30% of the excess familiar risk. What is contralaterally indicated when genetic assessment results negative for mutation in a young patient with unilateral breast cancer? Is it ethically correct to remove a contralateral “healthy” breast? CRRM rates continue to rise all over the world although CRRM seems not to improve overall survival in women with unilateral sporadic breast cancer. The decision to pursue CRRM as part of treatment in women who have a low-to-moderate risk of developing a secondary cancer in the contralateral breast should consider both breast cancer individual-features and patients preferences, but should be not supported by the surgeon and avoided as first approach with the exception of women highly worried about cancer. Prospective studies are needed to identify cohorts of patients most likely to benefit from CRRM.

Anal Melanoma With Neuroendocrine Differentiation: Report of a Case

Melanoma of the anal cavity is an uncommon malignant tumor with an aggressive clinical behavior. The presence of nonmelanocytic cell or tissue components, designated as divergent differentiation, is an unusual but well-documented phenomenon in melanoma. We experienced a rare case of amelanotic melanoma with neuroendocrine differentiation of the anal canal, occurring in a 68-year old woman. This tumor was characterized by a clear-cut radial growth phase and an invasive component composed of a diffuse small cells population positive for neuroendocrine markers with a focal but convincing co-expression of S100 protein. To the best of our knowledge, this represents the first case of neuroendocrine differentiation in a primary melanoma of the anal cavity. Although anal melanoma with neuroendocrine differentiation is exceptional, clinical practitioners should be aware of its possibility at this site.

A solitary fast growing red nodule of the abdomen

A 70-year-old woman presented with an asymptomatic red nodule on her abdomen (Figure 1). Physical examination revealed a 15 mm firm red nodule. The lesion had appeared two months prior and had rapidly grown. The nodule was excised. Histopathological examination showed a nodular, well-circumscribed dermal tumor with some cystic spaces and marked areas of vascular ectasia. The epidermis was not involved. The tumor demonstrated a trabecular pattern and was composed of two cell types: small basaloid cells lining the borders of trabeculae and aggregates of larger cell with pale nuclei closer to the centre. The tumor showed little atypia and a few focal mitoses (Figure 2). A solitary fast growing red nodule of the abdomen Case for Diagnosis

Donation of the body for scientific purposes in Italy: ethical and medico-legal considerations.

Abstract In recent years in Italy (and in the other European Countries) a new debated topic involves anatomists and the scientific world: donation of the body after death for scientific purposes. The aim of our analysis is to analyze the issue of voluntary body donation in Italy focusing first of all, on key principles of the disciplines of donation. Considering the rise of exhibitions and events in which death is spectacularized, the debate is focus on will, on respect and overall on the purpose for which the body is donated. Anatomical dissection is considered necessary in the direct learning of the human body, of surgical practices and new scientific techniques but the scarcity of programmes and regulations regarding the donation of bodies for study and research make it an uncommon practice. After discussing what are the constitutional principles underlying the issue we want to emphasize the need of a more effective and updated regulation to set limits and methods of a practice still essential for scientific progress.

The central importance of information in cosmetic surgery and treatments

Abstract The increase in the number of people who choose to have medical procedures done to improve their appearance may be due to changed social and cultural factors in modern society, as well to the ease of access and affordable costs of these cosmetic treatments. Today, two elements legitimate recourse to this type of treatment: the broad definition of health accepted by the law and the scientific community, and the provision of meticulous information to the entitled party previous to obtaining his or her consent. In Italy, while current case-law views treatments exclusively for cosmetic purposes as unnecessary, if not even superfluous, it nonetheless demands that providers inform clients about the actual improvement that can be expected, as well as the risks of worsening their current esthetic conditions.

Schnell wachsender rötlicher Knoten am Bauch

Eine 70-jährige Patientin stellte sich mit einem asymptomatischen rötlichen Knoten am Bauch vor (Abbildung 1). In der klinischen Untersuchung fiel ein 15 mm messender, fester Knoten auf, der anamnestisch seit 2 Monaten bestanden hatte und schnell gewachsen war. Nach chirurgischer Entfernung zeigte sich histopathologisch ein scharf begrenzter, nodulärer dermaler Tumor mit einigen zystischen Räumen und gebietsweiser Gefäßektasie. Die Epidermis war nicht betroffen. Der Tumor zeigte ein trabekuläres Muster und bestand aus zwei Zelltypen: kleinen basaloiden Zellen, die die Trabekelgrenzen auskleideten, und zentralen Aggregaten größerer Zellen mit abgeblassten Kernen. In dem Knoten fanden sich wenige Atypien und einige fokale Mitosen (Abbildung 2). Schnell wachsender rötlicher Knoten am Bauch A solitary fast growing red nodule of the abdomen Diagnosequiz
