[Evaluation of psychological disorders in patients with cancer of the oral cavity].

BACKGROUND AND AIMS: This study aimed to evaluate the possible onset of forms of anxiety, major and minor depression and behaviour towards the disease shown by patients with oral cavity neoplasms. METHOD: An explorative comparative study was performed in 28 patients referred to the department of Stomatological Surgery at the Odontostomatology Clinic of Turin University. Ten patients were examined before surgery and 18 after. The tests were performed using Hamilton's scale, STAI X1 and X2 and IBQ. These tests were carried out either during hospitalisation or during outpatient check-ups by an interviewer who was not familiar with the diagnosis or the patient's personal history. RESULTS: In the group of subjects evaluated before surgery, there was a scant presence of psychological correlations to disease. This shows that negation is widely used. Almost all subjects revealed the presence of anxiety symptoms and 60% of subjects were affected by minor depression. The level of negation was even higher in the postoperative group. This shows that the characteristics of the defensive structure did not change. CONCLUSIONS: Patients showed a psychological structure, even some time after surgery, which was similar to that in the first group of subjects, namely those facing an active phase pathology. The above findings underline the need for greater attention to be paid to the quality of life of these subjects who, owing to improved treatment, are becoming increasingly numerous. The scores obtained show that the majority of these patients encounter major difficulties at a psychological level, even if they manage to overcome the disease in physical terms. In conclusion, this study highlights the need to offer these subjects valid psychological support during diagnostic and therapeutic procedures. It also underlines the need for longitudinal studies in larger and more homogeneous groups of patients suffering from this disease since they appear to be somewhat neglected by modern literature.

[The chin hole. Position and correlation with other mandibular parameters].

BACKGROUND: The present study analyzes the position of mental foramen, in order to research possible correlations with other mandibular parameters. METHODS: The study has been conducted on 76 dry mandibles, for each mandible we have measured the exact position of the mental forum respect the other mandibular parameters. Both linear and angular relations and misurations have been made. RESULTS AND CONCLUSIONS: The results obtained confirm that the mental foramen maintains its position by increasing GoGn. The results did not show particularly significant aspects in comparison with the literature on the subject, thus confirming other authors' opinion.

[Surgical wound healing in oral surgery].

BACKGROUND: Aim of this study is to improve the in vivo knowledge about the real effects and the physiologic repair by a detached stitches silk suture in the 8th zone. METHODS: The study has been carried out on 44 patients submitted to surgical extraction of the impacted 8th (19 upper and 25 lower) teeth. RESULTS: Clinical and histological controls have demonstrated the usefulness of this suture procedure, since it gives a good histological reaction and in easy and safe. CONCLUSIONS: Histological and clinical results have confirmed the usefulness of silk suture, presenting however the inconvenience of stitches removal and bacterial plaque on the surgical wound.

[Orodental management in patients with malignant hematologic diseases who are waiting for bone marrow transplantation].

BACKGROUND: This study aims to identify the main oral lesions caused by the use of chemotherapeutic agents pre- and post-transplant in malignant hemopathologies and to highlight the importance of dental prevention during this treatment in order to reduce and, if possible, avoid the resulting local and systemic complications. METHODS: Twenty-five patients were controlled, monitored and prepared to undergo the necessary chemo- and radiotherapy, as well as bone marrow transplantation in the majority of cases under the best possible oral conditions. RESULTS: The most commonly detected secondary lesions were reactions to cyclophosphamide and/or methotrexate. In general, this mucositis appeared 5-7 days after treatment and continued for 1-2 weeks before regressing without residue. Another post-radiotherapeutic complication observed was xerostomy. CONCLUSIONS: Lastly, it is important to underline that patients receiving correct dental infection preventive treatment showed fewer tertiary lesions than those who did not undergo the same procedure.

[New suture techniques in oral surgery. Description and comparison with traditional sutures].

The study aimed to evaluate the healing of intraoral surgical wounds sutured with alpha-cyanoacrylate and silk in clinical and histological terms. Forty-four patients were checked 7 and 14 days after surgery. An incisional biopsy was made at the level of the discharge cut and histological tests were performed on the fragment. On the basis of the results, the authors affirm that in some areas (upper eighths), alpha-cyanoacrylate plays a useful role and simplifies the suture technique. On the contrary, this material was not sufficiently reliable in areas subject to excessive traction (lower eighths).

[A retrospective study on the importance of preoperative control in the prognosis of spinocellular carcinoma of the oral cavity].

Surgical treatment of advanced forms of spinocellular carcinoma of the oral cavity (stages 3-4) has been integrated for a number of years with cycles of chemo- and/or radiotherapy both before and after surgery. This chemo-radio-surgical therapeutic protocol consists of four distinct stages, separated by precise treatment-free intervals, which enable the best efficacy to be achieved through synergy. A total of 60 patients were treated by our Ward using this protocol during the period March 1988-June 1992. At the time of surgery a complete negative outcome in the histological picture (pTO) was observed in 40% of cases; lesions had not regressed on only 16% of patients. A retrospective type study has been carried out using Kaplan-Meier's statistical analysis to evaluate the prognostic factors in this population: a significant correlation was found between disease-free time and survival, calculated at 40 months from the completion of the protocol, and histopathological TNM. Non correlation was found with clinical TNM: therefore, rather than the extent of the lesion at the time of diagnosis, its control during preoperative stages appears to be the major prognostic factor.

[Verrucous carcinoma of the oral cavity. Personal experience with combined chemo-surgical treatment].

Following an introduction regarding the anatomo-pathological and clinical aspects of verrucous carcinoma of the oral cavity, the authors review several recent reports concerning the prognosis and treatment of this tumour and its possible evolution. This is followed by a wide-ranging discussion of the differing opinions put forward by various researchers regarding the possible role of radiotherapy and in particular the high risk of triggering off latent forms and provoking the differentiated and more aggressive forms of carcinoma. The authors then illustrate their experience of integrated chemo-surgical treatment, excluding radiotherapy, administered over the past six years to patients who were brought to their attention suffering from this form of carcinoma.

[Surgical experience of complex fractures of the middle third of the facial skeleton treated without an intermaxillary block].

Having illustrated the functional and anatomical aspects of the upper jaw and the importance of the anterior and posterior pillars as load-bearing structures for the middle third of face, the paper reports a series of fractures of the upper jaw treated with plaque osteosynthesis without an intermaxillary block. The functional and esthetic advantages are underlined.

[The correlation between dental pathology and ophthalmic pathology].

The study aims to assess the correlation between dental pathologies and ophthalmic diseases. Based on a statistical evaluation, the study examines the presence of dental diseases in patients suffering from optic neuritis or uveitis in comparison to a control group of subjects. The possible interactions between the two ophthalmic pathologies and dental diseases are then analyzed in order to highlight possible clinical signs which may be useful for their identification.
