Biliary cystadenoma is a rare benign tumour with the potential to transform into malignant carcinoma of the biliary ductal system. There is difficulty in differentiating a benign one from a malignant biliary cystadenoma, and therefore these lesions should always be completely resected. We report a case of biliary cystadenoma which underwent a complete resection.

BACKGROUND: Nummular eczema may mimic diseases that present with annular configuration and the differential diagnosis is broad.

OBJECTIVE: This article aimed to provide an update on the evaluation, diagnosis, and treatment of nummular eczema.

METHODS: A PubMed search was performed in using the key terms "nummular eczema", "discoid eczema", OR "nummular dermatitis". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature. The information retrieved from the above search was used in the compilation of the present article. Patents were searched using the key terms "nummular eczema", "discoid eczema", OR "nummular dermatitis" in www.google.com/patents and www.freepatentsonline.com.

RESULTS: Nummular eczema is characterized by sharply defined, oval or coin-shaped, erythematous, eczematous plaques. Typically, the size of the lesion varies from 1 to 10cm in diameter. The lesions are usually multiple and symmetrically distributed. Sites of predilection include the lower limbs followed by the upper limbs. The lesions are usually intensely pruritic. The diagnosis is mainly clinical based on the characteristic round to oval erythematous plaques in a patient with diffusely dry skin. Nummular eczema should be distinguished from other annular lesions. Dermoscopy can reveal additional features that can be valuable for correct diagnosis. Biopsy or laboratory tests are generally not necessary. However, a potassium hydroxide wet-mount examination of skin scrapings should be performed if tinea corporis is suspected. Because contact allergy is common with nummular eczema, patch testing should be considered in patients with chronic, recalcitrant nummular eczema. Avoidance of precipitating factors, optimal skin care, and high or ultra-high potency topical corticosteroids are the mainstay of therapy. Recent patents related to the management of nummular eczema are also discussed.

CONCLUSION: With proper treatment, nummular eczema can be cleared over a few weeks, although the course can be chronic and characterized by relapses and remissions. Moisturizing of the skin and avoidance of identifiable exacerbating factors, such as hot water baths and harsh soaps may reduce the frequency of recurrence. Diseases that present with annular lesions may mimic nummular eczema and the differential diagnosis is broad. As such, physicians must be familiar with this condition so that an accurate diagnosis can be made, and appropriate treatment initiated.

Diagnostic Accuracy of Cytology Smear and Frozen Section in Glioma

Mat Zin AA, Zulkarnain S

Asian Pac J Cancer Prev, 2019 Feb 26;20(2):321-325.

PMID: 30803189

Glioma is the commonest primary intracranial tumour and it has been the most predominant tumour in many studies.
It accounts for 24.7% of all primary brain tumour and 74.6% of malignant brain tumour. Intraoperative diagnosis
plays a crucial role in determining the patient management. Frozen section has been the established technique in
providing rapid and accurate intraoperative diagnosis. However due to some disadvantages like ice crystal artefact,
high expenditure and requirement of skilled technician, there is increase usage of cytology smear either replacing or
supplementing frozen section technique. The aim of this review is to determine the diagnostic accuracy of cytology
smear and frozen section in glioma and to see whether there is significant difference between those techniques. The
overall diagnostic accuracy for frozen section in glioma ranging from 78.4% to 95% while for cytology smear, the
diagnostic accuracy ranging from 50% to 100%. Based on certain literatures, no statistically difference was observed
in diagnostic accuracy of cytology smear and frozen section. Thus, cytology smear provides an alternative method in
establishing intraoperative diagnosis. Both cytology smear and frozen section are complimentary to each other. It is
recommended to use both techniques to improve the diagnostic accuracy in addition with adequate knowledge, clinical
history, neuroimaging and intraoperative findings.

Fulltext Spontaneous Omental Infarction: An Unusual Etiology of Abdominal Pain

Khairuddin A, Teng WW, Azizan N, Hayati F, Sahid NA, Kadir F

Kathmandu Univ Med J (KUMJ), 2019 10 1;17(68):347-349.

PMID: 33311048

A 49-year-old lady with previous scars complained of acute abdominal pain for two days. Her right hypochondrium was tender and guarding upon assessment. The laboratory investigations were unremarkable. Due to a diagnostic incongruity, computed tomography of the abdomen was performed showing a suspicious lesion at anterolateral aspect of the ascending colon. Surgical intervention was decided and intraoperative finding was consistent with spontaneous omental infarction. Omentectomy was undertaken and final histology was compatible with the intraoperative diagnosis. Although it is exceptional, omental infarction should be considered as part of the differential diagnoses of right-sided acute abdominal pain with normal laboratory investigations. This case highlights its unexpected discovery and we describe its literature reviews.

Comparison of the accuracy of the 7-item HADS Depression subscale and 14-item total HADS for screening for major depression: A systematic review and individual participant data meta-analysis

Wu Y, Levis B, Daray FM, Ioannidis JPA, Patten SB, Cuijpers P, et al.

PMID: 36689386 DOI: 10.1037/pas0001181

The seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item HADS (HADS-T) are both used for major depression screening. Compared to the HADS-D, the HADS-T includes anxiety items and requires more time to complete. We compared the screening accuracy of the HADS-D and HADS-T for major depression detection. We conducted an individual participant data meta-analysis and fit bivariate random effects models to assess diagnostic accuracy among participants with both HADS-D and HADS-T scores. We identified optimal cutoffs, estimated sensitivity and specificity with 95% confidence intervals, and compared screening accuracy across paired cutoffs via two-stage and individual-level models. We used a 0.05 equivalence margin to assess equivalency in sensitivity and specificity. 20,700 participants (2,285 major depression cases) from 98 studies were included. Cutoffs of ≥7 for the HADS-D (sensitivity 0.79 [0.75, 0.83], specificity 0.78 [0.75, 0.80]) and ≥15 for the HADS-T (sensitivity 0.79 [0.76, 0.82], specificity 0.81 [0.78, 0.83]) minimized the distance to the top-left corner of the receiver operating characteristic curve. Across all sets of paired cutoffs evaluated, differences of sensitivity between HADS-T and HADS-D ranged from -0.05 to 0.01 (0.00 at paired optimal cutoffs), and differences of specificity were within 0.03 for all cutoffs (0.02-0.03). The pattern was similar among outpatients, although the HADS-T was slightly (not nonequivalently) more specific among inpatients. The accuracy of HADS-T was equivalent to the HADS-D for detecting major depression. In most settings, the shorter HADS-D would be preferred.

Current methods in electrocardiogram characterization

Martis RJ, Acharya UR, Adeli H

Comput Biol Med, 2014 May;48:133-49.

PMID: 24681634 DOI: 10.1016/j.compbiomed.2014.02.012

The Electrocardiogram (ECG) is the P-QRS-T wave depicting the cardiac activity of the heart. The subtle changes in the electric potential patterns of repolarization and depolarization are indicative of the disease afflicting the patient. These clinical time domain features of the ECG waveform can be used in cardiac health diagnosis. Due to the presence of noise and minute morphological parameter values, it is very difficult to identify the ECG classes accurately by the naked eye. Various computer aided cardiac diagnosis (CACD) systems, analysis methods, challenges addressed and the future of cardiovascular disease screening are reviewed in this paper. Methods developed for time domain, frequency transform domain, and time-frequency domain analysis, such as the wavelet transform, cannot by themselves represent the inherent distinguishing features accurately. Hence, nonlinear methods which can capture the small variations in the ECG signal and provide improved accuracy in the presence of noise are discussed in greater detail in this review. A CACD system exploiting these nonlinear features can help clinicians to diagnose cardiovascular disease more accurately.
