Treatment for mental illness and substance abuse in a public psychiatric hospital. Successful strategies and challenging problems.

Although the literature on dual diagnosis has grown considerably over the last several years, report describing inpatient treatment models are less common. We describe some of the major treatment concerns in the dural diagnosis literature, such as using 12-step self-help programs like Alcoholics Anonymous (AA) or Narcotics Anonymous (NA), dealing with different stages of treatment, and developing a program with integrated substance abuse and psychiatric treatment. The practical application of these treatment issues is featured by showing how they are incorporated into an innovative inpatient dual diagnosis treatment program at a public psychiatric hospital. Finally, the treatment program is described in detail regarding administrative issues, staff training, daily treatment schedules, and patient demographics.

Benign lesions of the mandibular and maxillary region in children: characterization by CT and MRI.

The CT criteria for classifying lesions of the mandibular and maxillary regions in adults as benign or malignant are well recognized: irregular soft tissue margins and bone destruction. We reviewed the charts of 12 pediatric patients from 3 institutions to evaluate these criteria in children. These masses were evaluated by CT and/or MRI based solely on well-recognized and published criteria. The patients' ages ranged from 4 mo to 18 yr. The histological diagnoses were ameloblastoma (4), hemangioma (2), lymphangioma, desmoplastic fibroma, hemangiopericytoma, neurofibroma, fibrous dysplasia, and juvenile angiofibroma. All but one case was surgically proven. Among the 12 cases, 5 had bone destruction and 5 showed irregular soft tissue margins. Three cases satisfied both criteria. With well-recognized CT criteria (in adult patients), characterization of these processes led to an incorrect diagnosis of a malignant lesion in 8 of the 12 cases preoperatively. Therefore, CT and MR imaging should only be a guide to the planning and extent of surgical resection. Without clearly defined distal spread of the mass, the classification of these masses in children should be made with caution.

Mucinous cystadenocarcinoma of the parotid gland: report of a case with fine needle aspiration findings and histologic correlation.

BACKGROUND: Mucinous cystadenocarcinoma of the salivary gland is a rare entity. Review of the literature from 1991 to 1999 revealed no previous reports on its cytologic features. CASE: A 25-year-old man had a slowly growing, painless mass in the left parotid gland. Fine needle aspiration biopsy, performed prior to surgical excision, showed clusters of minimally atypical epithelial cells in which occasional vacuolated cells containing mucin could be seen. Pathologic evaluation of the resected parotid mass showed it to be a mucinous cystadenocarcinoma. CONCLUSION: The cytologic differential diagnosis of mucinous cystadenocarcinoma is with low grade mucoepidermoid carcinoma and with mucinous adenocarcinoma. Mucinous cystadenocarcinoma must be cystic; cysts may be present in low grade mucoepidermoid carcinoma, but their size and prominence varies. Mucinous adenocarcinoma is not cystic but gelatinous. Nuclei are bland in both mucinous cystadenocarcinoma and low grade mucoepidermoid carcinoma but are atypical in mucinous adenocarcinoma. There is no squamous differentiation in either mucinous cystadenocarcinoma or mucinous adenocarcinoma, but it is subtle in low grade mucoepidermoid carcinomas. Mucinous cystadenocarcinoma should be considered a potential candidate in the differential diagnosis of mucinous lesions that can occur in the salivary gland.

Longitudinal versus traditional residencies: a study of continuity of care.

BACKGROUND AND OBJECTIVES: Continuity of care is one of the presumed advantages of longitudinal residencies. However, it is not clear how well such residencies provide continuity of care, and, further, there is no recognized acceptable rate of good continuity. We compared traditional and longitudinal residencies to determine the extent to which the residents provided their patients with continuity of care. METHODS: We conducted a systematic chart review at three longitudinal and three matched traditional block-rotation programs. In total, 628 charts were reviewed, and 6,256 visits were evaluated. Continuity with a primary resident was evaluated over a 2-year period, with continuity defined as the percentage of visits for which the patient saw the same resident. RESULTS: There was no significant difference in overall rates of continuity between longitudinal and traditional programs (59.6% versus 57.8%). One longitudinal program, however, had a 74.8% rate of continuity, which was significantly higher than the rates in the otherfive programs. CONCLUSIONS: There was no significant difference found in continuity of care provided by residents at longitudinal programs, compared with those at traditional programs. Our results do not support the hypothesis that longitudinal residency programs achieve superior rates of continuity of care. Further comparison studies of longitudinal and traditional programs would be useful.

Ameloblastic carcinoma. A case report with review of literature.

Ameloblastic carcinoma is a rare odontogenic malignant tumour and has been a subject of great debate in literature. It does challenge the diagnostic acumen of pathologists, as this lesion needs to be detected at an early stage for adequate therapy. We present a case of the same with literature review.

Intracranial ependymoma and subependymoma: MR manifestations.

In order to provide a detailed description of the MR appearance of intracranial ependymoma, the MR examinations of 12 patients (10 with ependymomas and two with subependymomas) were reviewed and correlated with operative and pathologic reports. Three of 10 ependymomas were intraventricular, two were intraparenchymal, and five were transependymal, extending from CSF spaces into parenchyma. Both subependymomas were intraventricular. Solid ependymomas and subependymomas were iso- to hypointense relative to normal white matter on T1-weighted images and hyperintense on proton-density- and T2-weighted images. Foci of signal heterogeneity within solid neoplasms represented methemoglobin, hemosiderin, necrosis, calcification, and encased native vessels or tumor vascularity. Gd-DTPA-enhanced images in two patients differentiated enhancing tumor from surrounding nonenhancing edema and from surrounding normal brain parenchyma. Cystic neoplasms had sharply defined, round or oval margins and uniform signal intensity equivalent to or slightly hyperintense relative to CSF. Tumor-associated calcification was not demonstrated readily by MR. Sagittal and coronal images were valuable in assessing the amount of intraventricular tumor and route of extension. We conclude that the MR differentiation of ependymomas and subependymomas from other gliomas is provided most reliably by the location and morphology of the tumor and not by differences in signal intensity. The typical ependymoma arises within the fourth ventricle as a solid mass with heterogeneous signal intensity. A propensity for spread is seen along the CSF pathways via the foramina of Magendie and Luschka and the aqueduct of Sylvius. Supratentorial ependymomas may be periventricular in location and have cystic components. The two subependymomas in our series were solid, intraventricular tumors with relatively homogeneous signal intensities.

Continuous electrocardiographic monitoring during balloon dilatation in achalasia.

Electrocardiographic (ECG) changes in nine patients under continuous ECG monitoring before, during and after balloon dilatation for achalasia were followed; of these, three had ischaemic heart disease (IHD). One or several abnormalities including sinus tachycardia, supraventricular or ventricular ectopic beats, S-T segment depression and T-wave flattening appeared during the procedure; these were more commonly found in patients with IHD. Despite the high incidence of recorded ECG abnormalities, these were transient, and no treatment was needed. However, it seems advisable to have resuscitation equipment and emergency drugs available during balloon dilatation for achalasia, particularly when this procedure is performed in patients with IHD.

Continuous electrocardiographic monitoring during upper gastrointestinal endoscopy.

ECG changes were followed up in 69 patients under continuous electrocardiographic monitoring before, during and after esophago-gastro-duodenoscopy (EGD). Of these 32 (46.5%) had ischemic heart disease (IHD). One or more varied abnormalities including supraventricular or ventricular ectopic beats, sinus tachycardia or sinus bradycardia, intermittent right or left bundle branch block, S--T segment depression (and increased preexisting S--T segment depression), T wave flattening or inversion appeared during EGD. Only one patient with IHD developed anginal chest pain during endoscopy. Despite the high incidence of recorded rhythm abnormalities, these were transient, and no treatments were needed. However, it seems advisable to have resuscitation equipment and emergency drugs available during EGD, particularly when it is performed in patients with IHD.
