Salivary gland biopsy : experience of La Rabta Hospital's pathology departement

BACKGROUND: The minor salivary glands biopsy is a very common diagnostic procedure in oral medicine rather its efficiency has not been statistically proved. AIM: Assessment of Rabta pathologic department experience METHODS: 297 biopsies have been studied with special attention to the suspected diagnosis before biopsy and the final histologic result. RESULTS: The minor salivary gland biopsy confirmed the initial diagnosis in 78 cases. Although if the minor salivary gland biopsy is in most cases not contributively, it is a very simple procedure which gives the diagnosis of Gougerot-Sjogren disease, amylosis and sarcoidosis.     

Use of the national electronic maternal and child health registry (MCH eRegistry) in primary care clinics in occupied Palestinian territory: a pilot time-motion study

Background

In primary care maternal and child health clinics in occupied Palestinian territory, documentation and reporting consume considerable time for care providers. An electronic maternal and child health registry (MCH eRegistry), with point-of-care clinical decision support, is being implemented nationally in governmental clinics. We conducted a pilot study of time spent by care providers on important tasks, in preparation for a trial to compare eRegistry and non-eRegistry clinics.

Leucocytosis and thrombosis at diagnosis are associated with poor survival in polycythaemia vera: a population‐based study of 327 patients

Three hundred and twenty‐seven patients from two population‐based cohorts with an established diagnosis of polycythaemia vera were studied for prognostic risk factors for survival and leukaemia in a long‐term survey. The relative survival (RS) was 72% and 46% at 10 and 20 years respectively, from the time of diagnosis. Multivariate analysis identified age >70 years, white blood cell count >13 × 10⁹/l and thrombo‐embolism at diagnosis as independent risk factors. Patients with two or three of these factors had a 10 year RS of 26%, compared with 59% and 84% in patients with one and no risk factors, respectively. Age and leucocyte count are the main predicting factors for survival in polycythaemia vera.     

Genotypic distribution of human papillomavirus and phylogenetic analysis of E6 and E7 gene of HR-HPV variants isolated from Pakistani population

High-risk-human papillomavirus (HR-HPV)-induced cervical cancer is the second most common cause of death among females worldwide. HPV16 is the most prevalent HR-HPV infection worldwide. This study found the genotypic distribution of HR-HPV in the local population and investigated the sequence variations among the E6 and E7 oncogenes of the local HPV16 genotype to the E6 and E7 oncogenes of the foreign HPV16 genotypes and constructed a phylogenetic relationship based on nucleotide sequence comparison among the variants identified in our study along with previously reported isolates that were obtained from different regions of the world. The samples were collected from patients with cervical cancer. Genomic DNA was extracted, and HR-HPV genotypes were determined using real-time PCR. The HPV16 E6 and E7 genes were amplified and sequenced. A HPV16 phylogenetic tree was constructed using the maximum likelihood method with MEGA 7. HPV16 was the most prevalent human papillomavirus (HPV) type identified in the present study. HPV16 isolates belonged to the A1 sublineage of the European branch. Twenty-one nucleotide sequences were included in this analysis. The first, second, and third codon positions are also included. The final dataset included 776 positions.     

Late Infantile Neuronal Ceroid Lipofuscinosis in a Tunisian Boy

The classical form of late infantile neuronal ceroid lipofuscinosis is a childhood hereditary neurodegenerative disease usually fatal in the first decade of life. We report a two-year-old Tunisian boy who presented this form of ceroid lipofuscinosis. A febrile seizure was the presenting symptom without psychomotor delay. Magnetic resonance imaging of the brain showed mild cerebellar atrophy. Fundus oculi showed bilateral posterior polar cataract, which is a new finding in the classical form of late infantile neuronal ceroid lipofuscinosis. A homozygous R208X mutation was identified in the NLC2 gene. On follow up, this patient presented with myoclonic epilepsy and regression of acquired milestones.     

Outcome of men presenting with clinical breast problems: the role of mammography and ultrasound

The purpose of this study was to determine the outcome of men presenting with clinical breast problems for breast imaging and to evaluate the role of mammography and ultrasound in the diagnosis of benign and malignant breast problems. We retrospectively reviewed clinical, radiographic, and pathologic records of 165 consecutive symptomatic men presenting to Breast Imaging over a 4 year period. We assessed the clinical indication for referral, mammographic findings, sonographic findings, histologic results, and clinical outcomes. Patients ranged in age from 22 to 96 years. Breast Imaging Reporting and Data System (BI-RADS) category 4 and 5 mammograms and solid sonographic masses were considered suspicious for malignancy. Six of 165 men (4%) had primary breast carcinoma, which were mammographically suspicious in all 6 (100%). Five were invasive ductal carcinoma and one was ductal carcinoma in situ (DCIS). Of 164 mammograms, 20 (12%) were suspicious. Six were cancer and 14 were benign. Clinical follow-up for 2 years or biopsy results were available for 138 of the 165 men (84%). Twelve with benign mammographic findings had benign biopsies. All men with benign mammography not undergoing biopsy were cancer free. Sensitivity for cancer detection (mammography) was 100% and specificity was 90%. Positive predictive value (mammography) was 32% (6 of 19) and the negative predictive value was 100%. Sonography was performed in 68 of the 165 men (41%). Three of three cancers (100%) were solid sonographic masses. There were 9 of 68 false-positive examinations (13%). Sensitivity and negative predictive value for cancer detection (ultrasound) was 100% and specificity was 74%. The most common clinical indication for referral was mass/thickening (56%). Mammography had excellent sensitivity and specificity for breast cancer detection and should be included as the initial imaging examination of men with clinical breast problems. The negative predictive value of 100% for mammography suggests that mammograms read as normal or negative need no further examination if the clinical findings are not suspicious. A normal ultrasound in these men confirms the negative predictive value of a normal mammogram.
