Comparing the performance of the common used eumycetoma diagnostic tests.

OBJECTIVES: Mycetoma is a neglected tropical implantation disease caused by 70 different infectious agents. Identifying the causative organism to the species level is essential for appropriate patient management. Ultrasound, histopathology, culture and two species-specific PCRs are most the commonly used methods for species identification in endemic regions. The aim of this study was to compare the diagnostic performance of these commonly used assays using sequencing of barcoding genes as the gold standard. METHODS: This descriptive cross-sectional study was conducted at the Mycetoma Research Centre, University of Khartoum, Sudan. It included 222 patients suspected of fungal mycetoma caused by Madurella mycetomatis. RESULTS: 154 (69.3%) were correctly identified by ultrasound, histology, culture and both species-specific PCRs. In 60 patients, at least one of the diagnostic tests failed to identify M. mycetomatis. Five patients had no evidence of eumycetoma, and for three, only the ultrasound was indicative of mycetoma. The two species-specific PCRs were the most sensitive and specific methods, followed by culture and histology. Ultrasound was the least specific as it only allowed differentiation between actinomycetoma and eumycetoma. The time to result was 9.38 minutes for ultrasound, 3.76 hours for PCR, 8.5 days for histopathology and 21 days for grain culturing. CONCLUSION: Currently, PCR directly on DNA isolated from grains is the most rapid and reliable diagnostic tool to identify M. mycetomatis eumycetoma.

Mycetoma imaging: the best practice.

Mycetoma is a recognised neglected tropical disease that for a long time has been accorded inadequate attention across the globe. It is a chronic destructive inflammatory disease caused by fungi (eumycetoma) or actinomycetes (actinomycetoma). Mycetoma treatment depends on an accurate and precise diagnosis. The cornerstone for proper disease diagnosis is identification of the causative organisms, but also critical for diagnosis and management planning is determination of its extent along and across tissue planes. An initial diagnosis is made after clinical assessment. Clinical examination alone does not identify the causative organism nor does it detect the spread of disease along the different tissue planes and bone. Imaging techniques, such as radiography, ultrasonography, computed tomography scan and magnetic resonance imaging can be used to determine the extent of lesions. In this communication, the Mycetoma Research Centre, World Health Organization Collaborating Centre on Mycetoma, University of Khartoum, presents its experience and recommendations on mycetoma diagnostic imaging.

Estimation of sex based on the sterna of Sudanese adults using multidetector computed tomography: a comparison of discriminant function analysis and binary logistic regression.

Sex estimation is critical during forensic and anthropological investigations, and various techniques are used based on the presence of complete or fragmented human remains. This study evaluated sexual dimorphism in Sudanese sterna using multidetector computed tomography. This information was used to develop models for estimating sex, and to compare the accuracies of models based on discriminant function analysis (DFA) and binary logistic regression (BLR). The study included 126 Sudanese men and 144 Sudanese women who underwent computed tomography scans to create three-dimensional reconstructions. Six linear dimensions were measured on the manubrium and mesosternum. Men had larger mean values for most parameters, and nine parameters exhibited highly significant sexual dimorphism. The leave-one-out cross-validated sex estimation accuracies were 60.4-88.9% for DFA-based models and 60.4-89.3% for BLR-based models. The BLR-based models had noticeably better performances, with six parameters having sex estimation accuracies of >80% (vs. three parameters for DFA). The best BLR-based models incorporated the lengths and widths of the manubrium and mesosternum (accuracy: 89.3%, sex bias: 2.2%) and the combined manubrium and mesosternum lengths (accuracy: 85.6%, sex bias: 2.7%). Thus, computed tomography may be useful for measuring sternal dimensions and estimating sex among Sudanese subjects.

Arterial tree anomalies in patients with clubfoot: an investigation carried out at Soba University Hospital.

Vascular deficiencies and reduced perfusion of the anterior tibial artery and the dorsalis pedis artery were suggested as causes of congenital talipes equino varus (CTEV). In this study, we assessed the prevalence of arterial abnormalities in patients with CTEV (50 patients; 74 feet) compared with a normal control group (16 patients; 32 feet) by Doppler ultrasound and Ankle Brachial Index. The flow was normal in the control group and was deficient in 39.19% of clubfoot patients. In severe clubfoot cases, the deficiency was found to an extent of 76.67%. In conclusion, the anterior tibial artery and dorsalis pedis artery are deficient in CTEV patients; to avoid postoperative skin sloughing, arterial supply must be protected using a judicious incision.

Osteitis of the radius following Bacillus Calmette-Guérin vaccination at birth: a case report.

BACKGROUND: The Bacillus Calmette-Guérin vaccine, which is used for the prevention of tuberculosis, is considered protective against the severe forms of childhood tuberculosis. However, some serious adverse reactions including osteitis of the long bones can occur. CASE PRESENTATION: We report a case of an 18-month-old Sudanese girl who presented at the age of 3 months with swelling of her left forearm following Bacillus Calmette-Guérin vaccination administered at birth. Radiological and histological investigations confirmed tuberculous osteitis of the distal radius. She responded very well to antituberculous treatment with complete healing at follow-up visits. To the best of our knowledge this is the first case report of osteitis of the radius following Bacillus Calmette-Guérin vaccination described from Sudan. CONCLUSIONS: Bacillus Calmette-Guérin osteitis, although rare, should be considered a possible complication of the Bacillus Calmette-Guérin vaccination, and early diagnosis and treatment are essential.

Multicystic nephroma masquerading as hydatid cyst: a diagnostic challenge.

BACKGROUND: Multicystic nephroma is an uncommon, non-familial renal neoplasm that is usually benign. About 200 cases of this lesion have been described in the literature. CASE PRESENTATION: We report on a Sudanese child who presented at the age of two and a half years with an abdominal mass, clinical and radiological features favored the diagnosis of hydatid cyst which is endemic in this African tropical country, and the diagnosis of multicystic nephroma was only possible after histopathological examination. CONCLUSION: Multicystic nephroma is a rare benign tumour with an excellent prognosis. Clinical and radiological differentiation of multicystic nephroma from hydatid cyst is difficult. Thus, histopathological examination of the surgical specimens seems to be the only feasible method of making the correct diagnosis.

A Comparison of Sexual Function, Psychological Status, and Sociodemographic Characteristics of Turkish Men within Polygamous and Monogamous Marriages.

BACKGROUND: A limited number of studies within the literature have entailed objective evaluations of psychological, sexual, and emotional features of women within polygamous marriages. However, there is a lack of studies reporting these features among polygamous and monogamous men. AIMS: The aim of this study was to investigate sociodemographic characteristics, sexual function, and psychological status of polygamously and monogamously married men. STUDY DESIGN: Cross-sectional study. METHODS: The study sample comprised two groups: 35 polygamous and 45 monogamous men in Kahramanmaras Province, Turkey. Door-to-door surveys covered sociodemographic factors and adopted Beck Depression Inventory (BDI), and International Index of Erectile Function - Erectile Function Domain (IIEF-EFD) scales. RESULTS: Polygamous men showed considerably higher IIEF-EFD scores (p<0.05). While the median score of IIEF-EFD was 25.0 for polygamous men, it was 22.0 for monogamous men. A comparison of the two groups revealed that polygamous men had lower BDI scores. However, the difference between the groups was statistically non-significant (p>0.05). Odds ratios and 95% confidence intervals of monogamous men for erectile dysfunction and depression were 14.4 (95% CI: 3.1-67.5) and 7.4 (95% CI: 0.9-61.9), respectively. The main reasons for multiple marriages reported by polygamous men, in descending order, were: 1) decreased satisfaction of sexual desires by a wife (37.1%); 2) falling in love with the second wife (22.8%); and 3) incompatibility with the first wife (17.1%). However, 62.9% of them responded negatively to the question: "Would you recommend polygamous marriage to other men?" CONCLUSION: Our results showed that polygamous men had higher erectile function and lower depression scores than monogamous men. Further studies investigating the effects of polygamy on men's psychosexual function are warranted. Additionally, studies that address the perspectives of offspring and women's expectations within polygamous marriages should be conducted.

Does imprint cytology improve the accuracy of transrectal prostate needle biopsy?

OBJECTIVE: To evaluate the accuracy of imprint cytology of core needle biopsy specimens in the diagnosis of prostate cancer. METHODS: Between December 24, 2011 and May 9, 2013, patients with an abnormal DRE and/or serum PSA level of >2.5 ng/mL underwent transrectal prostate needle biopsy. Samples with positive imprint cytology but negative initial histologic exam underwent repeat sectioning and histological examination. RESULTS: 1,262 transrectal prostate needle biopsy specimens were evaluated from 100 patients. Malignant imprint cytology was found in 236 specimens (18.7%), 197 (15.6%) of which were confirmed by histologic examination, giving an initial 3.1% (n = 39) rate of discrepant results by imprint cytology. Upon repeat sectioning and histologic examination of these 39 biopsy samples, 14 (1.1% of the original specimens) were then diagnosed as malignant, 3 (0.2%) as atypical small acinar proliferation (ASAP), and 5 (0.4%) as high-grade prostatic intraepithelial neoplasia (HGPIN). Overall, 964 (76.4%) specimens were negative for malignancy by imprint cytology. Seven (0.6%) specimens were benign by cytology but malignant cells were found on histological evaluation. On imprint cytology examination, nonmalignant but abnormal findings were seen in 62 specimens (4.9%). These were all due to benign processes. After reexamination, the accuracy, sensitivity, specificity, positive predictive value, negative predictive value, false-positive rate, false-negative rate of imprint preparations were 98.1, 96.9, 98.4, 92.8, 99.3, 1.6, 3.1%, respectively. CONCLUSION: Imprint cytology is valuable tool for evaluating TRUS-guided core needle biopsy specimens from the prostate. Use of imprint cytology in combination with histopathology increases diagnostic accuracy when compared with histopathologic assessment alone.
