Background: The incidence of drug eruptions is increasing during the last few years due to a large number of new medications. Early detection of the causative agent and the prevention from exposure are crucial managements in terms of drug eruption, mainly to prevent its recurrence. Objective: To understand skin test as a diagnostic modality in drug eruption, which includes skin patch test, skin prick test, and intradermal test. Literature review: Drug eruption is a form of skin eruption triggered by the use of medications, topical or systemic, in the right dose and indication. The manifestation can vary from maculopapular, urticaria, pustular, and bullous eruption; from the most nonsignificant to a life-threatening reaction. A diagnostic procedure is critical to discover the type of drugs that cause the eruption, i.e., skin test, specific IgE measurement, histamine-release test, and provocation test. Skin test is the first choice in the diagnostic process as it is simple, easy, practical and has high sensitivity and specificity. Conclusion: Skin test is one of the many available diagnostic tools.  However, both false positive and false negative results might still arise. The experts are currently attempting to come up with more accurate and practical tests to aid the diagnostic of drug eruption, thus preventing its occurrence.

Skin test adalah suatu prosedur pemberian uji hipersensitifitas obat (alergi obat). Obat yang sering menimbulkan alergi adalah golongan β-lactam seperti penisilin dan sefalosporin sehingga pada penggunannya perlu adanya pemeriksaan skin test. Skin test diberikan melaui dua cara prick test dan intradermal test. Intradermal test masih menjadi pilihan pada uji alergi ini meskipun masih banyak perbedaan pendapat antara perlu atau tidaknya pemberian tersebut pada anak. Timbulnya nyeri saat dilakukan skin test intradermal menjadi alasan pemeriksaan ini dianggap tidak perlu untuk dilakukan. Jika pasien akan diberikan obat selain antibiotik maka skin test dianggap kurang efektif. Skin test menjadi penting saat pasien akan diberikan antibiotik terutama golongan sefalosporin karena sensitifitasnya tinggi pada reaksi tipe cepat meskipun pada reaksi tipe lambat pemeriksaan ini belum bisa diandalkan.

In accordance with the development of human technology, various medications have been speedily developed in the current decade. While they have beneficial impact on various diseases, these medications accidentally cause adverse reactions, especially drug eruption. This delayed hypersensitivity reaction in the skin sometimes causes a life-threatening adverse reaction, namely Stevens-Johnson syndrome and toxic epidermal necrolysis. Therefore, how to identify these clinical courses in early time points is a critical issue. To improve this problem, various biomarkers have been found for these severe cutaneous adverse reactions through recent research. Granulysin, Fas ligands, perforin, and granzyme B are recognized as useful biomarkers to evaluate the early onset of Stevens-Johnson syndrome and toxic epidermal necrolysis, and other biomarkers, such as miRNAs, high mobility group box 1 protein (HMGB1), and S100A2, which are also helpful to identify the severe cutaneous adverse reactions. Because these tools have been currently well developed, updates of the knowledge in this field are necessary for clinicians. In this review, we focused on the detailed biomarkers and diagnostic tools for drug eruption and we also discussed the actual usefulness of these biomarkers in the clinical aspects based on the pathogenesis of drug eruption.

Validated diagnostic tools to diagnose chronic neuropathic and mixed pain in children are missing. Therapeutic options are often derived from therapeutics for adults. To investigate the international practice amongst practitioners for the diagnosis and treatment of chronic, neuropathic pain in children and adolescents, we performed a survey study among members of learned societies or groups whose members are known to treat pediatric pain. The survey included questions concerning practitioners and practice characteristics, assessment and diagnosis, treatment and medication. We analyzed 117 returned questionnaires, of which 41 (35%) were fully completed and 76 (65%) were partially completed. Most respondents based the diagnosis of neuropathic pain on physical examination (68 (58.1%)), patient history (67 (57.3%)), and underlying disease (59 (50.4%)) combined. Gabapentin, amitriptyline, and pregabalin were the first-choice treatments for moderate neuropathic pain. Tramadol, ibuprofen, amitriptyline, and paracetamol were the first-choice treatments for moderate mixed pain. Consensus on the diagnostic process of neuropathic pain in children and adolescents is lacking. Drug treatment varies widely for moderate, severe neuropathic, and mixed pain. Hence, diagnostic tools and therapy need to be harmonized and validated for use in children.

Background Allergy skin test reliability depends on the reagents and controls selected. Histamine is used at 1 mg/ml and 6 mg/ml concentration but few studies address the rationale for selecting one versus the other and how this may impact diagnostic accuracy. Objective To determine the rate of false negative allergen skin tests responses between UniTest PC (using the 1 mg/mL histamine) and Quintip devices (using 6 mg/mL) for 4 common aeroallergens. Methods Subjects aged 18-65 with symptoms of allergy to cat and/or ragweed received skin testing with 4 aeroallergens (dust mite mix, timothy grass, ragweed, cat), histamine and control diluent. Those individuals who tested positive to cat or ragweed with one skin prick test (SPT) device but not the other then proceeded to nasal allergen challenge (NAC). The primary outcomes were the aeroallergen false negative rates and sensitivities of the skin test devices followed by nasal allergen (NAC). Results Twenty-five individuals were recruited and underwent a total of 300 SPTs. SPT to allergens (ragweed, dust mite, cat, and timothy grass) resulted in a statistically significant difference in wheal size among the two skin testing devices ( p value <0.0001, 0.0001, 0.0006, and 0.0053 respectively). Six NAC procedures were performed to cat/ragweed and 5 of 6 (83% were positive). The overall allergen sensitivity rate for UniTest and Quintip were 97% and 78% respectively with most false negatives due to the use of 6 mg/ml histamine control reagent. Conclusion Our study shows that 6 mg/ml concentration of histamine control reagent may contribute to a false interpretation of aeroallergen skin prick test results.

<b><i>Objectives:</i></b> Cytology and histology are 2 indispensable diagnostic tools for cancer diagnosis, which are rapidly increasing in importance with aging populations. We applied mass spectrometry (MS) as a rapid approach for swiftly acquiring nonmorphological information of interested cells. Conventional MS, which primarily rely on promoting ionization by pre-applying a matrix to cells, has the drawback of time-consuming both on data acquisition and analysis. As an emerging method, probe electrospray ionization-MS (PESI-MS) with a dedicated probe is capable to pierce sample and measure specimen in small amounts, either liquid or solid, without the requirement for sample pretreatment. Furthermore, PESI-MS is timesaving compared to the conventional MS. Herein, we investigated the capability of PESI-MS to characterize the cell types derived from the respiratory tract of human tissues. <b><i>Study Design:</i></b> PESI-MS analyses with DPiMS-2020 were performed on various type of cultured cells including 5 lung squamous cell carcinomas, 5 lung adenocarcinomas, 5 small-cell carcinomas, 4 malignant mesotheliomas, and 2 normal controls. <b><i>Results:</i></b> Several characteristic peaks were detected at around m/z 200 and 800 that were common in all samples. As expected, partial least squares-discriminant analysis of PESI-MS data distinguished the cancer cell types from normal control cells. Moreover, distinct clusters divided squamous cell carcinoma from adenocarcinoma. <b><i>Conclusion:</i></b> PESI-MS presented a promising potential as a novel diagnostic modality for swiftly acquiring specific cytological information.

AbstractThe article refers to resources, problems and challenges of autism diagnosis and support system in Poland. The resources include: the increasing number of specialists, diagnostic and therapeutic centres, well-established course of education for people working with youths, standardised and normalised diagnostic tools. The diagnostic process is not without some areas in need of our focus: the tendency of some specialists to make unauthorised diagnosis, overshadowing; underestimation of comorbidity of ASD with other disorders. The challenges refer to introducing an effective system of monitoring the services provided in form of certification and control in order to prevent their abuse, initiating category of temporary diagnosis; paying more attention on individual’s resources, better cooperation among specialists, teachers and families, developing and unifying diagnostic standards.

In adult patients with acute lymphoblastic leukemia (ALL), Central Nervous System (CNS) involvement is associated with a very poor prognosis. The diagnostic assessment of this condition relies on the use of neuroradiology, conventional cytology (CC) and flow cytometry (FCM). Among these approaches, which is the gold standard it is still a matter of debate. Neuroradiology and CC have a limited sensitivity with a higher rate of false negative results. FCM demonstrated a superior sensitivity over CC, particularly when low levels of CNS infiltrating cells are present. Although prospective studies of large series of patients are still awaited, a positive finding by FCM appears to anticipate an adverse outcome even if CC shows no infiltration. Current strategies for adult ALL CNS-directed prophylaxis or therapy involve systemic and intrathecal chemotherapy and radiation therapy. Actually, early and frequent intrathecal injection of cytostatic combined with systemic chemotherapy is the most effective strategy to reduce the frequency of CNS involvement. In patients with CNS overt ALL, at diagnosis or upon relapse, allogenic hematopoietic stem cell transplantation might be considered. This review will discuss risk factors, diagnostic techniques for identification of CNS infiltration and modalities of prophylaxis and therapy to manage it.

Objective: This study aimed to identify cases of leishmaniasis in the Nuba Mountain area, which is situated in a unique geographical site located in the centre of Sudanese leishmania belt. Wide range of investigations are available for detection of leishmania cases, but still the most reliable and easy test used as screening and epidemiological tool in field studies needs to be evaluated. The most commonly used conventional diagnostic methods direct microscopy and culture have some drawbacks in diagnosing subclinical cases of leishmaniasis. Materials and methods: In this study, comparative properties of various immune-diagnostic tools with Polymerase Chain Reaction used in sub-clinical leishmaniasis isolates were explored. The immune-diagnostic tools involved in this study include- Leishmanin Skin Test (LST), Enzyme Linked Immunosorbent Assay (ELISA) and Direct Agglutination Test (DAT). The study was conducted in the Green Valley village (Rashad Province, South Kordofan State) with a population of 332. Most of the villagers presented with sub-clinical form of leishmaniasis with minor symptoms and signs without the features found in clinical form of visceral leishmaniasis such as fever, diarrhoea, epistaxis, enlarged lymph nodes, spleen and liver. In this study we collected demographic, clinical and epidemiological data using special questionnaire. Leishmanin skin test (LST), ELISA, DAT and PCR for parasite DNA detection were used. Result: The final positive cases detected by PCR were 32 out of 332 belong to L. donovani species. The final positive cases detected by LST were 51.2% of the total population under study, while 11 out of the 37 tested samples were positive by ELISA. All of the 332 villagers showed negative readings by DAT with exception of three individuals who were positive with very high titers. Conclusion: DNA etxtraction and amplification with primers can be a good screening tool in subclinical leishmaniasis isolates.

Background Hysterosalpingography (HSG) is a useful screening test for the evaluation of female infertility. Laparoscopy has proven role in routine infertility work up but role of hysteroscopy in an infertile patient with normal HSG for additional information is a subject of debate. Hysteroscopy permits direct visualization of the cervical canal and the uterine cavity and thereby helping in the evaluation of shape, and cavitary lesion.Objective To detect uterine abnormalities in infertile women by various approaches i.e. HSG and hysteroscopy and evaluating the role of combining hysteroscopy with laparoscopy for the evaluation of tubo-uterine factor for primary infertility.Method One twenty eight infertile women were evaluated and HSG was performed as a basic test for evaluation of tubes and uterine cavity. Women were subjected to combined laparoscopic and hysteroscopic examination on evidence of HSG abnormalities. In absence of any HSG abnormality, women were subjected to ovulation induction for three to six months and if they did not conceive during this period they were undertaken for combined laparo-hysteroscopic evaluation.Result The positive predictive value of HSG for detecting the intrauterine abnormalities was 70% among 126 patients where the hysteroscopy could be performed successfully. The diagnostic accuracy of HSG for intrauterine abnormalities revealed false negative rate of 12.96%. The most frequent pathologies encountered by laparoscopy were tubal and/or peritoneal and were found in 68% (87/128) of women. Total 64.06% infertile women had some abnormality on laparoscopy. This detection rate has been increased from 64.06% to 71.86% on including the concomitant hysteroscopy.Conclusion HSG is a good diagnostic modality to detect uterine as well as tubal abnormalities in infertile patient. HSG and hysteroscopy are complementary to each other and whenever the patient is undertaken for diagnostic laparoscopy for the infertility, hysteroscopy should be combined to improve the detection rate of abnormalities especially in communities where there is enormous risk of pelvic infection.
