Background: Delayed in diagnosis and treatment of tuberculosis will increase the risk of MDR TB. WHO recommends Xpert MTB/RIF as diagnostic tools to identify MDR TB. Availability of Xpert MTB/RIF is still limited, another diagnostic tool is needed. Neutrophyl lymphocyte ratio (NLR) was presumed to be able to identify the probability of MDR TB. The aim of this study is to evaluate the comparison of NLR in tuberculosis and MDR TB patients. Methods: This is an analytic descriptive study with case series approach in Adam Malik General Hospital Medan. This study held since January – December 2015 with number of sample as much as 100 bacteriological confirmed TB patients and 100 MDR TB patients. We performed leukocyte differential count from peripheral blood examination to obtain NLR Result: Mean NLR of TB patient 4.62±2.37 and MDR TB 3.28±1.44. There was significant difference of NLR between both groups using Mann-Whitney test (P=0.001). The cut off value by ROC analysis was 2.91 with sensitivity, specificity, positive predictive value, negative predictive value and accuracy was 77%, 50%, 60.6%, 68.4% and 63.5% respectively. Conclusion: There was significant difference of NLR between bacteriological confirmed TB patients and MDR TB patients. Value of NLR

  The World Health Organization (WHO) recommended microscopic AFB smear examination and culture as follow-ups to the response of MDR TB therapy. Analyzed the results of microscopic AFB smear and culture conversion as well as treatment outcome in Multidrug-Resistant Tuberculosis (MDR-TB) patients with and without Diabetes Mellitus (DM). This is a retrospective study involved 70 MDR-TB patients with (27 patients) with DM and without DM (43 patients) who had microscopic AFB smear and culture results at the start of the follow-up therapy. This research was conducted at Labuang Baji Regional Public Hospital, Makassar, from June to July 2019, used medical records of MDR-TB patients the period of June 2016 to December 2017. The results showed that 52 out of 70 MDR-TB patients had microscopic AFB smear and culture conversion in MDR-TB with DM (21 patients) and without DM (31 patients). The duration of microscopic AFB smear conversion in MDR TB patients with DM (3.33±0.54 months) was longer than patients without DM (2.07±0.05 months), p=0.001. While in culture conversion, there was no significant difference between MDR-TB with DM (1.28±0.64 months) and without DM (1.25±0.59), p=0.648. The recovery outcome between MDR-TB with (48.1%) and without DM (48.8%) was not significantly different. However, the output of treatment failure was greater in DM (11.2%) than without DM (2.3%), although statistically, there was no significant difference (p=0.568). Multidrug-resistant tuberculosis patients with DM experienced slower microscopic AFB smear conversion than MDR-TB patients without DM. However, in culture, there was no significant difference in the conversion period between the two groups. MDR-TB patients, both of with and without DM, had the same chance of recovery.

OBJECTIVEIntraoperative neuromonitoring (IOM), particularly of somatosensory-evoked potentials (SSEPs) and motor-evoked potentials (MEPs), evolved as standard of care in a variety of neurosurgical procedures. Case series report a positive impact of IOM for elective microsurgical clipping of unruptured intracranial aneurysms (ECUIA), whereas systematic evaluation of its predictive value is lacking. Therefore, the authors analyzed the neurological outcome of patients undergoing ECUIA before and after IOM introduction to this procedure.METHODSThe dates of inclusion in the study were 2007–2014. In this period, ECUIA procedures before (n = 136, NIOM-group; 2007–2010) and after introduction of IOM (n = 138, IOM-group; 2011–2014) were included. The cutoff value for SSEP/MEP abnormality was chosen as an amplitude reduction ≥ 50%. SSEP/MEP changes were correlated with neurological outcome. IOM-undetectable deficits (bulbar, vision, ataxia) were not included in risk stratification.RESULTSThere was no significant difference in sex distribution, follow-up period, subarachnoid hemorrhage risk factors, aneurysm diameter, complexity, and location. Age was higher in the IOM-group (57 vs 54 years, p = 0.012). In the IOM group, there were 18 new postoperative deficits (13.0%, 5.8% permanent), 9 hemisyndromes, 2 comas, 4 bulbar symptoms, and 3 visual deficits. In the NIOM group there were 18 new deficits (13.2%; 7.3% permanent, including 7 hemisyndromes). The groups did not significantly differ in the number or nature of postoperative deficits, nor in their recovery rate. In the IOM group, SSEPs and MEPs were available in 99% of cases. Significant changes were noted in 18 cases, 4 of which exhibited postoperative hemisyndrome, and 1 suffered from prolonged comatose state (5 true-positive cases). Twelve patients showed no new detectable deficits (false positives), however 2 of these cases showed asymptomatic infarction. Five patients with new hemisyndrome and 1 comatose patient did not show significant SSEP/MEP alterations (false negatives). Overall sensitivity of SSEP/MEP monitoring was 45.5%, specificity 89.8%, positive predictive value 27.8%, and negative predictive value 95.0%.CONCLUSIONSThe assumed positive impact of introducing SSEP/MEP monitoring on overall neurological outcome in ECUIA did not reach significance. This study suggests that from a medicolegal point of view, IOM is not stringently required in all neurovascular procedures. However, future studies should carefully address high-risk patients with complex procedures who might benefit more clearly from IOM than others.

BackgroundDiagnosis of congenital syphilis (CS) is not straightforward and can be challenging. This study aimed to evaluate the validity of an algorithm using timing of maternal antisyphilis treatment and titres of non-treponemal antibody as predictors of CS.MethodsConfirmed CS cases and those where CS was excluded were obtained from the Guangzhou Prevention of Mother-to-Child Transmission of syphilis programme between 2011 and 2019. We calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) using receiver operating characteristics (ROC) in two situations: (1) receiving antisyphilis treatment or no-treatment during pregnancy and (2) initiating treatment before 28 gestational weeks (GWs), initiating after 28 GWs or receiving no treatment for syphilis seropositive women.ResultsAmong 1558 syphilis-exposed children, 39 had confirmed CS. Area under the curve, sensitivity and specificity of maternal non-treponemal titres before treatment and treatment during pregnancy were 0.80, 76.9%, 78.7% and 0.79, 69.2%, 88.7%, respectively, for children with CS. For the algorithm, ROC results showed that PPV and NPV for predicting CS were 37.3% and 96.4% (non-treponemal titres cut-off value 1:8 and no antisyphilis treatment), 9.4% and 100% (non-treponemal titres cut-off value 1:16 and treatment after 28 GWs), 4.2% and 99.5% (non-treponemal titres cut-off value 1:32 and treatment before 28 GWs), respectively.ConclusionsAn algorithm using maternal non-treponemal titres and timing of treatment during pregnancy could be an effective strategy to diagnose or rule out CS, especially when the rate of loss to follow-up is high or there are no straightforward diagnostic tools.

ABSTRACT: BACKGROUND: A common surgical emergency is acute appendicitis. Various diagnostic tools are available to diagnosis acute appendicitis. Radiological investigations play an important role in making accurate and early diagnosis and thus preventing morbidity associated with the disease. OBJECTIVE: To determine the diagnostic accuracy of gray scale ultrasonography versus color Doppler in suspected cases of acute appendicitis. MATERIALS AND METHODS: The study was carried in the department of Radiology of Mayo Hospital, Lahore. A total of 75 patients were enrolled of age 18-40 years, both genders who were suspected cases of acute appendicitis. All patients underwent baseline investigations along with gray scale ultrasonography and color Doppler. All patients were subjected to surgery to confirm the diagnosis and findings were subjected to statistical analysis. RESULTS: The mean age of the patients was 23.25 ±10.55 and mean transverse diameter of appendix was 8.37 ±3.39. There were 62.7% males and 37.3%females. Findings of gray scale ultrasonography and color Doppler were then correlated with surgical findings to calculate the diagnostic accuracy of these modalities. The results revealed that gray scale ultrasonography sensitivity, specificity, positive predictive value, negative predictive value and accuracy was 92.7%, 94.32%, 95%, 91.4% and 93.3% respectively, whereas color Doppler had sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 97.7%, 93.9%, 95.3%, 97% and 96% respectively. Diagnostic accuracy of both modalities together was 98.6%. CONCLUSION: Color Doppler has better diagnostic accuracy than gray scale ultrasonography for diagnosis of acute appendicitis and the combination of both modalities yields diagnostic accuracy that is similar to gold standard.

Objective The present study evaluated the reliability of digital panoramic radiography in the diagnosis of carotid artery calcifications. Materials and Methods Thirty-five patients under high-risk for development of carotid artery calcifications who had digital panoramic radiography were referred to undergo ultrasonography. Thus, 70 arteries were assessed by both methods. The main parameters utilized to evaluate the panoramic radiography reliability in the diagnosis of carotid artery calcifications were accuracy, sensitivity, specificity and positive predictive value of this method as compared with ultrasonography. Additionally, the McNemar's test was utilized to verify whether there was a statistically significant difference between digital panoramic radiography and ultrasonography. Results Ultrasonography demonstrated carotid artery calcifications in 17 (48.57%) patients. Such individuals presented with a total of 29 (41.43%) carotid arteries affected by calcification. Radiography was accurate in 71.43% (n = 50) of cases evaluated. The degree of sensitivity of this method was 37.93%, specificity of 95.12% and positive predictive value of 84.61%. A statistically significant difference (p < 0.001) was observed between the methods evaluated in their capacity to diagnose carotid artery calcifications. Conclusion Digital panoramic radiography should not be indicated as a method of choice in the investigation of carotid artery calcifications.

Cochlear Dysfunction

Background: Longterm exposure to aminoglycoside such as kanamycin to cochlear cells is known to be associated with damage to outer hair cells in the organ Cortiand type 1 sensory hair cells in the vestibular organs which ultimately causes permanent damage to hair cells. Hair cell damage occurs from the basal cochlea (high frequency area) to the apex cochlea (low frequency area) and followed by damage from the auditory nerve. Evaluation of cochlear dysfunction on multidrug resistant tuberculosis (MDR TB) patients have been rarelyreported in the literature based on distortion product otoacoustic emission (DPOAE).Objectives: To prove cochlear dysfunction after kanamycin injection in MDR TB patient based on DPOAE examination of the overall frequencies and specific frequency.Methods: An observational longitudinal analytic with pre and post design without control group conducted in the infection division of MDR TB Outpatients Pulmonology Department and Otorhinolaryngology Community division of ORL-HNS Department Dr. Soetomo general hospital Surabaya, within 3 months in 2018, 15 ear with the best baseline examination were taken by consecutive sampling and statistical analysis for cochlear dysfunction based on overall  frequency and specific frequency DPOAE examination using Mc Nemar test.Results: Based on DPOAE examination of overall frequencies there was no cochlear dysfunction (p > 0.05) but a significant difference was found at frequency of 10,000 Hertz (Hz) (p = 0.002 ).Conclusion:On ototoxicity monitoring there was no cochlear dysfunction after 4 weeks  Kanamycin injection but cochlear dysfunction occurs at a specific frequency of 10,000 Hz.

Background Anal cytology may form the basis of a future screening program to prevent anal carcinoma. Therefore, the accuracy of anal Papanicolaou tests in detecting histological HSIL needs to be evaluated. Methods: SPANC is a 3-year prospective study in homosexual men aged ≥35 years. At each of five visits, men undergo collection of a ThinPrep® anal cytological sample, high-resolution anoscopy (HRA) and biopsy of any abnormalities. Cytology is reported using the Bethesda system. Histology is reported using lower anogenital squamous terminology. Results: 351 men had a baseline visit by end July 2013. Median age was 49 (range: 35–79) years and 101 (28.8%) men were HIV positive. Anal cytology results were: unsatisfactory in 21 (6.0%), negative in 143 (40.7%), ASC-US in 51 (14.5%), LSIL in 22 (6.3%), ASC-H in 45 (12.8%) and HSIL in 69 (19.7%). 293 of 351 (83.5%) men had baseline histology. The most severe abnormality for each was: negative for SIL in 98 (33.4%), LSIL in 87 (29.7%) and HSIL in 108 (36.9%). Anal cytology sensitivity for histological HSIL (at ASC-US threshold) was 79.0%. Specificity was 53.8%. Positive predictive value (PPV) of any cytological abnormality for histological HSIL was 44.4% and PPV of HSIL cytoprediction was 63.8%. Negative predictive value (NPV) was 84.6%. Overall there was no significant difference between HIV positive and negative men with respect to sensitivity, specificity, PPV or NPV. Conclusions: These results indicate that histological HSIL is common in homosexual men. The finding of any cytological abnormality should prompt HRA. However, both cytology and HRA can miss or underestimate significant lesions in a single screening.

We aim to assess the usefulness of the cytomegalovirus CMV pp65 antigenaemia test, also called the CMV direct antigen test DAT , in the management of patients with advanced human immunodeficiency virus HIV infection; we studied all patients who had pp65 assays between 8 September 1995 and 30 August 1996. Twenty three patients had 31 tests. The mean CD4 cell count was 20 mm 3. The tests were negative in 16 patients, of whom 12 have not developed CMV end organ disease after a mean follow up of 114 days range 14- 269 days , whilst the remaining 4 patients had previously treated CMV disease. Eleven patients had positive tests: 4 had active CMV disease, 2 subsequently developed CMV retinitis, 2 died within a fortnight of multi drug resistant tuberculosis MDR TB , one was lost to follow up and 2 have remained disease free. This test has a positive predictive value of 43 and a negative predictive value of 94 , Fisher s exact test P =0.03. The pp65 antigenaemia assay can be performed in a standard virology laboratory avoiding the problems associated with polymerase chain reaction PCR , a result is available within 5 h, and it is semi quantifiable. However, a large prospective study is required to determine the comparative value and roles of the pp65 antigenaemia assay and DNA PCR in the management of CMV disease, especially with regard to the use of primary prophylaxis and pre emptive therapy.
