RESUMEN
BACKGROUND: Patients suffering from Cushing's disease are known to be restricted due to a wide range of symptoms. Despite biochemical cure, symptoms might last life-long. These include - among well-known somatic symptoms - several neuropsychiatric symptoms that cannot be as easily tested, but lead to a serious negative impact on quality of life. We aimed to evaluate what factors diminish the self-perceived quality of life the most using 3 questionnaires visualizing those impairments. Furthermore we investigated whether there would be differences in quality of life between patients still being affected by the disease and those that are already in remission. PATIENTS AND METHODS: We reviewed patient charts treated between April 2008 and June 2012 for Cushing's disease and sent 3 questionnaires to the patients for evaluation. For this purpose we used the SF-36, the BDI and the Tuebingen CD-25. 54 patients complied with our request and returned the completed questionnaires. The average time after surgery was 36 months. RESULTS: In all 8 dimensions of the SF-36 significant differences between the patient collective and the expected age- and gender-specific scores could be observed and thus a detectable impairment in quality of life. The BDI revealed that every other patient suffering from Cushing's disease presented depressive symptoms, partially with clinical relevance. In all 6 dimensions of the Tuebingen CD-25 there were notable restrictions in patients. Those restrictions particularly concerned bodily restrictions and cognitive performance. The self-perceived quality of life of active patients was - although not statistically significant - in almost all measured fields worse than the test results of patients in remission after TSS. CONCLUSION: Former and active Cushing's disease patients suffer from a wide range of neuropsychiatric symptoms. Those symptoms might dominate the clinical picture and lead to a serious impairment in quality of life as well as extend periods of suffering and might persist even years after being found healthy. Therefore it is important to evaluate quality of life as an independent factor in every patient being affected by Cushing's disease and to include a holistic view in their therapy. Concomitant therapeutic measures should be accessible at any time for Cushing's disease patients as the normalization of pathologically increased laboratory values doesn't obligatory lead to an improvement of the patients subjectively felt well-being.

Pituitary tumors may lead to cognitive dysfunction, and the most prevalent deficits are impaired memory and attention. To investigate whether memory and executive functions improve after surgical treatment we performed a prospective longitudinal study comprising 106 patients with pituitary tumors. Psychometric evaluation was performed with the d2-Letter Cancellation test, the Trail Making test, the Digit Span test and the Intelligence Structure test-Verbal Memory test at three timepoints: preoperatively, and at 3 months and 12 months after surgery. The preoperative and postoperative maximum suprasellar tumor extension and hormone status was assessed in all participants. The main finding was that concentration, working memory, and attentional speed improved significantly within the first 3 months after surgery (p<0.05), while improvement of episodic memory was not observed until 12 months after surgery (p<0.001). In the patients harbouring non-functioning adenomas, prolactinomas or other sellar lesions, the most important factor promoting improvement of neurocognitive function was the removal of the suprasellar tumor extension.

OBJECTIVE: The aim of the study was to analyze the time-to-diagnosis interval in patients with Cushing's disease (CD) and acromegaly (AC), to assess factors that promote early disease detection and to investigate the medical fields diagnosing the pathologies. METHODS: 33 CD and 52 AC patients operated over 10 years received a self-designed disease-related questionnaire. Data about symptoms and their duration prior to diagnosis, education level, age, gender and place of residence (i. e. rural vs. urban, size of the city) were collected. RESULTS: The mean time-to-diagnosis interval was 6.0 years in CD and 5.8 years in AC patients. The vast majority of 67% of all investigated patients was diagnosed after they changed their primary health care provider or during a hospital stay owing to comorbidities caused by their underlying disease. Only 33% of all cases were diagnosed by their primary physician. In both groups neither gender, age, place of residence, education level, typical comorbidities (e. g. hypertension or diabetes) nor distinctive symptoms and bodily changes of the underlying disease (e. g. prognathism, acral enlargement, weight gain, buffalo hump) were significant factors promoting early detection. CONCLUSIONS: Apparently, patient-related factors do not affect the time-to-diagnosis interval, but rather the change of the primary health care provider. Knowledge of the disease among physicians is prerequisite to early detection. Due to the deleterious sequelae of delayed diagnosis, information programmes in the medical community are of paramount importance. Institution of screening programmes should be evaluated.

BACKGROUND: Cushing's disease (CD) and acromegaly (AC) are associated with impairment in quality of life (QoL) and neurocognition that can persist after successful treatment. AIM: To investigate the influence of current disease status (remission vs no remission) on neurocognitive function and QoL in treated CD and AC patients and to determine predictive factors (e.g. demographic, clinical, neurosurgical, endocrinological) for post-operative neurocognition and QoL. SUBJECTS AND METHODS: Twenty-four CD and 37 AC patients underwent neuropsychological testing 1 to 10 yr following surgical therapy. Additionally, QoL was assessed. An overnight 2-mg dexamethasone suppression test in CD and IGF-I and GH levels in AC patients were assessed to determine current disease status. The results were compared with 28 sex-, education- and age-matched healthy controls (HC). RESULTS: Impaired QoL was more pronounced than neurocognitive decrease in both pathologies compared to HC. This finding was independent of the current status of disease. In AC, persistent comorbidities were associated with impaired QoL (p<0.05). Older age at operation in AC patients was a significant predictor for adverse effects on psychomotor speed and attentional functions (p<0.05). In CD persistent hypocortisolism, not hypercortisolism, had adverse effects on neurocognition (p<0.01). CONCLUSIONS: The current status of disease plays a subordinate role in postoperative outcome concerning QoL and neurocognition in either pathology. A possible explanation might be the considerably improved endocrinopathy after treatment compared to untreated patients, even if no cure is achieved. The lasting impairments might be explained by irreversible changes that have occurred during the active phase of the disease.

OBJECTIVE: Acromegaly is associated with deleterious comorbidities that can remain irreversible even after successful cure has been achieved and lead to a persistently impaired Quality of Life (QoL). The aim of the study was to assess frequency and degree of persistent comorbidities and complaints after treatment of acromegaly and to investigate their impact on QoL. Another scope of interest was to determine gender-specific factors that influence perceived QoL in men and women. METHODS: We developed an Acromegaly Comorbidities & Complaints Questionnaire (ACCQ) consisting of 8 items (e. g. acral enlargement, joint complaints, hypertension, diabetes) known to affect QoL in order to assess frequency and degree of comorbidities. Additionally, the Acromegaly Quality of Life Questionnaire (AcroQoL) and the Short-form 36 (SF-36) questionnaire were handed out to 55 treated acromegalic patients. RESULTS: Both genders suffer from a lasting impairment in quality of life to a considerable degree. Complaints impairing manual skills (e. g. acral enlargement, arthralgias) were the most frequent findings (73% of all participants) in both genders. Multivariate analyses revealed that in men numbness of fingers and persistent joint-complaints were decisively responsible for impaired QoL. In women, it was the persistence of hypertension. CONCLUSIONS: Persistent joint complaints have adverse effects on QoL after treatment of acromegaly in men, possibly because they lead to impairment of manual motor skills and a handicap in their working life. Women seem to perceive late effects of hypertension as a manifest health threat.

The first orthotopic heart transplantation (OHT) was performed in 1967 by C.N. Barnard in Cape Town, South Africa. The first OHT in Cuba was performed in 1985. The main purpose of our study was to determine some of the aspects related to the short-, mid-, and long-term morbimortality rates of OHT patients in Cuba. We analyzed the first 120 OHTs (3 heart plus lung transplantations, 4 retransplantations, and 113 heart transplantations) which were performed in Cuba from December 1985 to December 2005. Based on the analysis, we performed a descriptive, retrospective research about morbimortality. There was a predominance of the masculine sex (5.31:1). The overall mean age was 45.13 +/- 11.58 years (range, 14-67 years). The most frequent pretransplant diagnosis was coronary artery disease (CAD; n = 69; 57.5%). Analyzing the Kaplan-Meier survival curve, we observed that the survival probability at 1 year was 83.3%; at 5 years, 45.7%; and at 10 years 19.2%. The complications by frequency were: sepsis (n = 41; 37%), acute rejection episodes (n = 42; 35.0%), and neoplasia (n = 4; 3.3%). Complications in frequency order were sepsis and acute rejection episodes among short term and chronic rejection and chronic renal failure among long-term survivors.

A 42 year-old male, smoker, was referred for evaluation of an ulcer located in the gingiva, during one month, that produced disturbances. On the intraoral examination we appreciated an ulceration of 0.5 cm, on a mandibular torus, in the lingual gingiva of the left first molar (Fig. 1-2). A panoramic x-Ray (Fig. 3), a CT scan (Fig. 4) and a biopsy were taken (Fig. 5-6, Fig. 6 is a S-100 stain).

BACKGROUND: We present a series of 10 patients with osteonecrosis of the jaws (ONJ) that appeared following cancer chemotherapy. MATERIAL AND METHODS: Of the 10 cases with ONJ, six had bone metastases from breast cancers and the other four had multiple myeloma. We analysed the location of bone metastases, as well as the characteristics of the ONJ, and the drugs with which they had been treated for their bone metastases. RESULTS: Of the 10 patients, all had ONJ in the mandible; 50% also had maxillary involvement. The average number of areas of painful exposed was 2.1 per patient (range 1-5). In seven patients a tooth extraction preceded the onset of ONJ. Two patients developed oroantral communications and another a cutaneous fistula to the neck with suppuration. In all the 10 patients the histopatholological diagnosis was of chronic osteomyelitis without evidence of metastatic disease to the jaws. All the patients had received treatment for their malignant bone disease with bisphosphonates. These were the only drugs that all patients had received. CONCLUSION: ONJ appears to have a relationship with the use of bisphosphonates.

Lichen sclerosus et atrophicus (LSA) is a chronic mucocutaneous inflammatory disorder of uncertain aetiology that is clinically characterized by the appearance of well delimited white plaques or papules, preferentially affecting the skin and genitals, and more rarely the oral cavity. We present the case of a woman with LSA limited to the oral cavity in the form of a well delimited, flat whitish lesion affecting the vestibular gingiva of the right upper incisors and left central incisor, and extending towards the vestibular fundus and frenulum of the upper lip. Widening of the periodontal space was observed, with gingival recession and attachment loss limited to these teeth. Local corticosteroid injections caused the mucosal lesion but not the periodontal alterations to resolve. Emphasis is placed on the importance of knowledge of this condition in relation to establishing a diagnosis, and on its periodontal repercussions.

Leishmaniasis is a parasitic disease caused by a protozoon (Leishmania), with different clinical forms that are endemic in certain countries. The association of this disease in patients who are seropositive to human immunodeficiency virus (HIV) has recently been described. Leishmaniasis can develop in any stage of HIV infection, although the clinical manifestations - and hence the diagnosis - tend to coincide with the periods of maximum immune depression. We present the case of a HIV-positive, ex-intravenous drug abuser (in stage B2 of the CDC, 1992) with concomitant hepatitis C infection who presented with palatinal pain and bleeding for the past 2 months. Exploration revealed a vegetating tumoration of the hard palate. Hematoxylin-eosin and Giemsa staining of the biopsy confirmed the diagnosis of leishmaniasis. The definitive diagnosis was mucocutaneous leishmaniasis (MCL), for a bone marrow aspirate proved negative, and no further lesions could be established. The patient was treated with meglumine antimoniate (Glucantime), followed by improvement of the lesions.

Angiocentric lymphomas are very infrequent neoplasms in our geographical setting. They tend to develop in the oronasal region in the form of necrotic lesions--specifically in the midfacial zone--with a rapid course and poor prognosis. Immunohistochemically, the malignant cells have been shown to correspond to T lymphocytes. In addition, recent research supports the possible role of Epstein-Barr virus as a possible etiological factor. We present the case of a 67 year old man with an ulcerated palatinal lesion of recent appearance that was diagnosed as angiocentric lymphoma by histopathological and immunohistochemical study. Following diagnosis, treatment was provided in the form of 3 cycles of CHOP type chemotherapy and radiotherapy.

Langerhans' cell histiocytosis comprises a group of disorders with Langerhans' cell proliferation as a common feature. The clinical presentation might be highly varied. Typically, there is bone involvement and, less frequently, lesions might be found in other organs, particularly the lungs, liver, lymph nodes, skin, and mucosae. Lesions limited to the oral mucosa are rare. We describe two patients with unifocal eosinophilic granuloma exclusively limited to the oral mucosa. Triamcinolone acetonide infiltration of a palatal lesion yielded a good result in one patient. Six months later, a similar lesion developed in the mandibular gingival mucosa, but it responded to the same treatment. The lesion in the other patient responded to local radiotherapy.

OBJECTIVES: A study of the dental, periodontal, oral mucosal and salivary condition of adult patients with chronic renal failure (CRF) receiving hemodialysis (HD). MATERIAL AND METHODS: A total of 105 patients on HD were studied, together with 53 healthy age and sex-matched controls. Indices employed included carious, absent and obturated teeth index (CAO index), plaque index, calculus index and loss of periodontal attachment. Whole and parotid salivary secretions were also measured. RESULTS: The CAO index was not significantly higher among HD patients than controls (14.9 +/- 8.7 vs 13.3 +/- 7.9, respectively; t = 1.1; P = 0.3). However, plaque and calculus indices were significantly higher in HD patients (2.1 +/- 0.8 and 2.3 +/- 0.6, respectively) than controls (1.3 +/- 0.8 and 1.6 +/- 0.9) (P < 0.001). Loss of periodontal attachment was similar in both groups (4.9 +/- 2.5 vs 4.2 +/- 2.5 in the HD patients and controls, respectively) (t = 1.8; P = 0.07). There was no more oral mucosal pathology in HD patients than in controls (chi-square = 5.8; P = 0.3). Stimulated salivary secretion was significantly higher in controls than HD patients for both whole (t = -5.2; P < 0.001) and parotid (t = -2.6; P = 0.01) salivas. CONCLUSIONS: The results show significantly higher plaque and calculus indices and lower salivary secretion among the HD patients than in healthy controls.

OBJECTIVE: The purpose of this study was to analyze the importance of psychologic factors in patients with oral lichen planus, and attempts were made to identify possible personality features characteristic of patients with oral lichen planus. STUDY DESIGN: The study involved 100 patients with oral lichen planus (group 1) and 50 control subjects (group 2). We applied the following psychometric tests to both groups: Spielberger State-Trait Anxiety Inventory, Cattell Personality Questionnaire 16PF, Hassanyeh Rating of Anxiety-Depression-Vulnerability, Beck Depression Inventory, Raskin Depression Screen, and Covi Anxiety Screen. RESULTS: The patients with oral lichen planus were found to exhibit greater anxiety, as reflected by statistically significant scores with the anxiety tests that were used (Spielberger State-Trait Anxiety Inventory, Cattell Personality Questionnaire 16PF, Hassanyeh Rating of Anxiety-Depression-Vulnerability, and Covi Anxiety Screen). The patients with oral lichen planus likewise exhibited greater depression than the controls in all 3 depression tests applied (Beck Depression Inventory, Hassanyeh Rating of Anxiety-Depression-Vulnerability, and Raskin Depression Screen) and were more vulnerable to psychic disorders on the basis of the PD subscales (vulnerability) of the Hassanyeh questionnaire. Three features (conformity to the group, astuteness, and rebelliousness) defined the personalities of our patients with oral lichen planus, according to the Cattell 16PF questionnaire. Finally, those patients with erosive lichen planus exhibited higher depression scores than patients with nonerosive lichen planus. CONCLUSIONS: Despite the higher anxiety scores observed in patients with oral lichen planus, it was not established that the observed psychologic alterations constitute a direct etiologic factor of oral lichen planus; nor was it established that such alterations are a consequence of oral lichen planus and its lesions.

BACKGROUND: The aim of the present study was to investigate the existence of differences in dental status and in quantitative and qualitative salivary values between 100 patients with liver cirrhosis (LC) and a group of controls. MATERIAL AND METHODS: We analyzed the number of carious, missing and filled teeth. Also the unstimulated (UWS) and stimulated whole saliva flow rates (SWS) were determined, along with the stimulated parotid saliva flow rate (PSS) and the concentration in both UWS and SWS of sodium, potassium, total proteins and immunoglobulin A (IgA). RESULTS: A significantly higher number of carious and missing teeth was observed in the patients with cirrhosis (2.4 and 14.6, respectively) than in the control group (1.3 and 10.6, respectively), and a higher stimulated parotid flow rate with LC (0.64 and 0.44, respectively; p < 0.02) with a decrease in sodium and an increase in potassium, total proteins and IgA in patients with cirrhosis. In the LC group, caries were found to affect more teeth in those patients with alcohol-induced LC than in those with liver disease of other causes (3.9 and 1.7, respectively; p < 0.05), but in contrast, no differences were found in the saliva flow rate and the concentration in both UWS and SWS of sodium, potassium, total proteins and IgA. Finally, no relationship was observed between the dental status and functional hepatic tests. CONCLUSIONS: CH patients showed a worse dental status, a higher SPS rate and some electrolytes and proteins alterations.

OBJECTIVE: The aim of this investigation was to determine if an association exists between hepatitis C virus and oral lichen planus. STUDY DESIGN: Three groups of subjects were selected: 505 patients with hepatitis C virus infection (group 1), 100 patients with oral lichen planus (group 2), and a randomly selected control group (age- and gender-matched) of 100 healthy subjects (group 3). The prevalence of oral lichen planus was determined in groups 1 and 3, and the prevalence of hepatitis C virus infection was established in groups 2 and 3. RESULTS: The prevalence of oral lichen planus was 3.36% (n = 17) in group 1 and 1% (n = 1) in the control group; the prevalence of hepatitis C virus infection was 23% (n = 23) in group 2, and 5% (n = 5) in the control group. No significant differences were observed in the incidence of oral lichen planus in group 1 between those patients who received interferon and those who did not. The 17 patients in group 1 who manifested oral lichen planus and hepatitis C virus infection simultaneously exhibited a marked tendency to have only reticular lesions (70.6%), with involvement of the buccal mucosa in 88.2% of these patients, the tongue in 29.4%, and the gingiva in 11.8%. Analyzing a randomized subgroup of 143 patients from group 1 (subgroup 1) that was matched by age and gender with groups 2 and 3, we found that the incidence of oral lichen planus in patients with hepatitis C virus infection (subgroup 1) was greater than in the control group (5.59% vs 1%), though this was not statistically significant (chi2 = 0.119; p = 0.06). In contrast, group 2 exhibited a statistically significant higher incidence of hepatitis C virus infection (23%) than the controls (5%; chi2 = 0.259, p = 0.0002). CONCLUSIONS: The prevalence of hepatitis C virus infection in patients with oral lichen planus was greater than in the control series. In our opinion this observation warrants the investigation of potential concomitant hepatitis C virus infection in patients with oral lichen planus.
