Family functioning and suicidality in depressed adults.

This study examined the association between suicidality, family factors, and clinical and diagnostic variables in depressed adult inpatients. The subjects were 121 depressed adult inpatients living with a family member or significant other. Demographic, clinical, and diagnostic information about the patient, and subjective and observer ratings of family functioning were obtained. Trained interviewers rated families of suicidal depressed patients as more dysfunctional than families of patients with no history of attempted suicide. In a logistic regression model, earlier age of depression onset, number of psychiatric hospitalizations, and objectively rated poorer family communication were associated with a history of a prior suicide attempt. Also, modest evidence suggested that patients with a prior suicide attempt perceived their families as more dysfunctional than did their respective family members. Variations in family functioning are associated with different degrees of suicidality. However, prospective longitudinal designs would elucidate the causal relation between family dysfunction and suicidal behavior.

Persistence of depressive symptoms and cardiovascular death among patients with affective disorder.

OBJECTIVE: Studies of both community and clinical samples have associated depressive symptoms with risks for subsequent cardiovascular morbidity and mortality. Because the physiological mechanisms thought to underlie this link would be cumulative in their effects, the following analyses tested the prediction that risks for cardiovascular death would increase in proportion to the persistence of depressive symptoms in a long-term follow-up. METHODS: Baseline assessment was performed as patients sought treatment for major depressive disorder, mania, or schizo-affective disorder. Follow-up evaluations occurred semiannually for the next 5 years and annually thereafter. The 903 patients described, observed for a mean of 11.0 years (SD = 5.2 years), were divided into thirds according to the proportion of follow-up weeks in episodes of major depressive disorder, schizoaffective disorder, or intermittent depressive disorder. The resulting groups were then compared by cumulative risks of cardiovascular death. RESULTS: Patients whose depressive symptoms were the most persistent were no more likely to die of cardiovascular causes than were those with the fewest weeks ill. A regression analysis showed that older age and the presence of cardiovascular disease at baseline, but not the subsequent chronicity of depressive symptoms, predicted cardiovascular death. CONCLUSIONS: The physiological concomitants of depressive illness apparently do not promote cardiovascular mortality in a cumulative manner. Efforts should be directed toward identification of risk factors common to both lifetime depressive symptoms and cardiovascular morbidity.

Terminology. International Academy of Cytology Task Force summary. Diagnostic Cytology Towards the 21st Century: An International Expert Conference and Tutorial.

ISSUES: Differences in type, structure, quality of health care systems and availability of resources influence reporting systems. In most countries, individual systems have a long history of usage that might preclude adoption of a uniform terminology worldwide. CONSENSUS POSITION: It is desirable but unrealistic at this time to aim for a unified terminology worldwide. It should be the stated objective of the International Academy of Cytology to serve as an umbrella organization for various terminologies and enhance mutual understanding and cooperation. Translation tables of equivalent terms have been created to allow increased communication. Consensus has been achieved in defining essential elements required of any terminology system: (1) the report must be text based: numerical Papanicolaou class designations alone are inadequate; (2) an assessment of the adequacy of the sample should be included; and (3) the diagnosis must address the primary purpose of cervical cytology: to indicate the presence or absence of epithelial abnormalities. Incorporating additional elements within a terminology system may be more or less appropriate, depending on the setting in which the system is used. ONGOING ISSUES: Despite the cited problems in adopting a uniform terminology worldwide, a single system would have many advantages in terms of communication and research and may be a long-term goal worth pursuing. Countries are invited to present their individual national terminology systems and participate in an ongoing dialogue, critically evaluating the advantages and disadvantages of all systems.

ASCUS and AGUS criteria. International Academy of Cytology Task Force summary. Diagnostic Cytology Towards the 21st Century: An International Expert Conference and Tutorial.

ISSUES: The conference participants addressed the following issues: (1) reporting of equivocal diagnoses, (2) strategies to minimize the use of such diagnoses, (3) morphologic criteria, and (4) management of women with equivocal diagnoses. CONSENSUS POSITION: Equivocal diagnoses should be minimized, to the extent possible, by emphasizing cytologist education and training, improved specimen collection and quality assurance monitoring of individual and laboratory diagnosis rates. Cases fulfilling criteria for other diagnostic entities should not be included in the equivocal category. Regardless of the term utilized, an equivocal diagnosis should be qualified in some manner to indicate that the diagnosis defines a patient at increased risk of a lesion, particularly for those cases which raise concern about a possible high grade lesion. Qualification of an equivocal diagnosis can also be accomplished by appending laboratory statistics of the likelihood of various clinical outcomes or recommendations for patient follow-up. In contrast to favoring a reactive process versus squamous intraepithelial lesion (SIL), a more rationale approach to qualification of atypical squamous cells of undetermined significance may be to separate cases equivocal for low grade SIL from those suspicious for high grade SIL. With regard to glandular lesions, the conference participants expressed unanimous support for the separation of adenocarcinoma in situ (AIS) from atypical endocervical cells of undetermined significance when sufficient criteria are present. However, the diagnosis of a precursor lesion to AIS, endocervical glandular dysplasia, was controversial. The majority of conference participants discourage the use of such terms as mild glandular dysplasia and low grade glandular dysplasia for cytologic diagnoses. ONGOING ISSUES: Conference participants agreed that a term reflecting diagnostic uncertainty is necessary to communicate findings that are equivocal. However, participants could not agree on the wording of such a term. Opinions differed as to: (1) use of atypical, abnormal or morphologic changes to describe cell changes, (2) whether the diagnosis should indicate a squamous or glandular origin of the cells in question when this determination can be made, and (3) the value of defining morphologic criteria for such a diagnosis. The debate over terminology, as well as morphologic criteria, is ongoing, and the readership is invited to communicate opinions to Acta Cytologica. Management of women with equivocal diagnoses varies widely from locale to locale and may differ based on how the equivocal diagnosis is qualified. Findings insufficient for the diagnosis of a high grade lesion may warrant more aggressive follow-up than cases equivocal for a low grade lesion. Where sensitivity of detection of lesions is of paramount importance, follow-up will generally consist of more frequent cytology screening or colposcopy and biopsy. However, in some countries it is considered unethical to have a high percentage of false positive diagnoses, which result in overtreatment and an unnecessary burden for women participating in cervical screening. Future studies may provide a morphologic, or perhaps molecular, basis for distinguishing true precursors of neoplasia from minor lesions of no significant clinical import; this would allow a more coherent and rational approach to diagnosis and management of women with equivocal cytologic findings.

Cell preparation methods and criteria for sample adequacy. International Academy of Cytology Task Force summary. Diagnostic Cytology Towards the 21st Century: An International Expert Conference and Tutorial.

ISSUES: Cell Preparation Methods Standardized fixation and optimal staining Sampling of cervix, sampling error, homogenization of sample, subsampling Assessment of liquid-based preparations: efficacy and economic impact Training and transitional procedures before full implementation of new technologies Criteria for Sample Adequacy Clinician responsibility for collecting and providing representative sample to laboratory Collection instruments, number of slides Cellular content of samples: evidence of transformation zone (TZ) sampling, number of squamous cells present, obscuring factors Screening issues CONSENSUS POSITION The conventional cervical smear remains the standard method of cervical cancer screening but has limitations in individual test sensitivity and specificity. Sample takers should: (1) receive appropriate training in sample collection, (2) be held responsible for providing the laboratory with appropriate samples, and (3) have their performance monitored. The instruments used for sampling should collect cells from both the ectocervix and endocervix; optimally, TZ sampling, represented by the presence of endocervical or squamous metaplastic cells, should be identifiable in samples other than atrophic specimens. The adequacy of a specimen (as judged microscopically) does not guarantee that it is representative of the cervix. Each cytology report should include a comment on cellular content/adequacy of the specimen. Liquid-based preparations may overcome many of the inherent problems with the conventional cervical smear. ONGOING ISSUES: We need further data on the cost-effectiveness of making two slides from cervical specimens and/or using two samplers rather than a single one. Do we have enough information to make recommendations as to the appropriate type of sampler to be used in particular situations, such as routine screening? What is the best method of screening for/detecting endocervical glandular neoplasia? How are such terms as unsatisfactory and inadequate defined in cervical cytology classifications other than the Bethesda System? What number and types of epithelial cells should be present (visualized) in a cervical smear or liquid-based preparation for it to be considered adequate? Do we need to have evidence of TZ sampling in specimens taken during the follow-up period after treatment of squamous intraepithelial lesion or after detection of endocervical glandular neoplasia? What criteria for obscuring factors, such as blood and inflammation, should be used in assessing adequacy? Cost-benefit analyses of utilizing liquid-based preparations are needed. Should we inform women about the technical details of the test methods available or chosen by the laboratory? Are women in a position to decide which method is the most appropriate to assess their cervical scrape sample? We need to obtain more information about the properties of proprietary liquid fixative/transport media with respect to inactivation of viral pathogens, tuberculosis and other bacterial pathogens and suitability for immunobiologic and molecular tests, etc. We need to obtain more information on the use of stoichiometric stains and the limitations of Papanicolaou stain for image analysis systems. The use of liquid-based preparations for nongynecologic cytopathology and ancillary tests must be considered, including criteria for adequacy. We need to obtain more information on the time required for and best methods of training experienced cytotechnologists to become competent at assessing liquid-based cervical preparations.

Tumor-infiltrating lymphocytes. Cytologic, phenotypic and morphometric analysis.

OBJECTIVE: To characterize the cytologic, phenotypic and morphometric features of tumor-infiltrating lymphocytes (TILs). STUDY DESIGN: Morphology and cell size parameters of 50 TILs and five normal donor peripheral blood lymphocyte (PBL) specimens were compared using light microscopy, manual ocular measurements and digital image processing. RESULTS: Cytologically, all TILs demonstrated similar morphologic findings regardless of the initial tumor type. Changes included large; eccentric nuclei, sometimes hyperlobated; clumped chromatin; and prominent nucleoli. The cytoplasm was abundant and basophilic. Mitotic figures were usually evident. In addition, TIL showed significant increases in cell size parameters as compared to PBLs. CONCLUSION: The activated morphology of TILs resembles the appearance of high grade lymphoma. Several cell size parameters are increased; that may help to explain differences in previously reported trafficking patterns between TILs and peripheral blood lymphocytes.

Sound- and pressure-induced vertigo associated with dehiscence of the roof of the superior semicircular canal.

In many types of peripheral vertigo, imaging is not part of the initial evaluation. We present a patient with sound- and pressure-induced vertigo associated with bony dehiscence of the roof of the superior semicircular canal. The diagnosis of this new entity can only be made by high-resolution coronal CT imaging of the temporal bones. In patients with this symptom complex, CT should be performed early in the diagnostic workup.

Pneumocystis carinii in pleural fluid. The cytologic appearance.

We describe the cytologic appearance of Pneumocystis carinii in pleural fluid of a patient with acquired immunodeficiency syndrome and a rapidly accumulating pleural effusion. The diagnosis of P carinii infection was made by examination of air-dried, Diff-Quik-stained Cytospin preparations of the pleural fluid. The diagnostic appearances of P carinii organisms stained by this method and by the Papanicolaou stain are reviewed. The unusual predominance of the trophozoite forms of the organism in this case made Diff-Quik an ideal special stain for identifying the organisms. Furthermore, this case illustrates a novel presentation of P carinii infection and suggests that P carinii should be considered an etiologic agent in the differential diagnosis of pleural effusion in an immunocompromised host.

Detection of the von Hippel-Lindau gene deletion in cytologic specimens using microdissection and the polymerase chain reaction.

Previous studies have demonstrated von Hippel-Lindau (VHL) gene abnormalities in renal cell carcinoma. Archival cytologic samples of renal cell carcinomas (RCCs) from two patients were evaluated for allelic loss of the VHL gene. Small clusters of renal carcinoma cells were dissected from cytocentrifuge preparations under direct microscopic visualization followed by single-step DNA extraction and subsequent polymerase chain reaction (PCR). Amplification of DNA from the harvested tumor cells demonstrated a loss of heterozygosity at the VHL gene in five RCC specimens obtained from two patients. The combination of microdissection and PCR enabled DNA studies to be performed on a pure population of tumor cells isolated from heterogeneous samples containing admixed normal cellular elements. Selected genetic studies performed on microscopically targeted cells will help to further the biologic and cytomorphologic characterization of the targeted cell population.
