Study of pattern and time-reaction sequence for adverse drug reactions reported to antiretroviral drugs

Background: Adverse drug reactions (ADRs) to antiretroviral drugs have a varied pattern and wide spectrum of severity from mild to very serious. The lack of a pre-established time-reaction sequence hampers the causality assessment of ADRs. Recognition of pattern of ADRs to antiretroviral drugs in a particular setup might sensitize the reporters to report ADRs, especially in setups dependent on spontaneous reporting. Aim and Objectives: The study of pattern and time-reaction sequence for ADRs reported to antiretroviral drugs. Materials and Methods: Retrospective study was conducted at a first-line antiretroviral therapy (ART) center after obtaining approval from the Institutional Ethics Committee. Pattern of ADRs associated with ART was done by analyzing the type of ADRs, severity, and outcome of ADRs reported to antiretroviral drugs. Mean duration of time lapse between administration of drug to onset of adverse drug reaction was calculated. Descriptive statistics was used for data analysis. Results: There were 73 adverse reactions reported. Most common type of adverse reaction was cutaneous (53.42%) followed by anemia (31%). Causality assessment of most ADRs was concluded as possible (60.27%). Most ADRs were of moderate severity and 12% were severe reactions. Reactions such as anemia and neuropsychiatric ADRs often occurred late, while maculopapular rash usually occurred within 30 days of drug administration. Conclusions: ADRs to ART include an array of reactions ranging from mild rash to psychosis or severe anemia. Most of these reactions are of moderate severity and have a favorable outcome. Many of these reactions actually occur almost a month after initiating a drug regime suggesting the need for intensive monitoring around this time.

Compression of images of dermatological manifestations of paucisymptomatic COVID-19 patients through periodic principal components / Compresión de imágenes de manifestaciones dermatológicas de pacientes paucisintomáticos de COVID-19 mediante componentes principales periódicos

Introduction: The management of medical images has been gaining followers based on the advantages it offers for the diagnosis of diseases, which, like COVID-19, present with clinical manifestations that can be captured in the form of images. Objective: Take advantage of the quasi-periodicity of the principal components (PCs) in the decomposition into PCs of medical images, which represent dermatological manifestations in paucisymptomatic patients of COVID-19. Methods: Here, a set of photos was taken of one of the most frequent patterns in COVID-19, the maculopapular pattern, characterized by an erythmatopapular rash, and compression of one of the medical images was performed. Said compression was carried out in different ways: (1) using two PCs, (2) using both a periodic PC and a non-periodic PC, (3) using two periodic PCs, (4) using a single PC, and (5) using a single periodic PC. Result: The results of this research proved that it is possible to work with acceptable reconstructions of compressed images in the field of dermatology, without losing the quality and characteristics that allow to reach a correct diagnosis. In addition, this achievement permits to correctly classify many diseases without fear of being wrong. Conclusion: With the method presented, the use of a robust medical image compression technique that could be very useful in the field of health is proposed. The images allow the diagnosis of diseases such as COVID-19 in paucisymptomatic patients, understanding them allows minimizing their weight without losing quality, which facilitates their use and storage.

Introducción: El empleo de imágenes médicas en el diagnóstico de enfermedades ha ido ganando adeptos. Un ejemplo es la COVID-19 que cursa con manifestaciones clínicas dermatológicas. Objetivo: Aprovechar la cuasi-periodicidad de los componentes principales de la descomposición en imágenes médicas, que representan manifestaciones dermatológicas en pacientes paucisintomáticos de COVID-19. Métodos: Se tomó un conjunto de fotografías de uno de los patrones más frecuentes en la COVID-19 (el patrón maculopapular), caracterizado por un exantema eritematopapular, y se realizó la compresión de una de las imágenes médicas. Dicha compresión se realizó de diferentes formas: (1) usando dos componentes principales, (2) usando tanto un componente principal periódico como no periódico, (3) dos componentes principales periódicos, (4) un único componente principal, y (5) un solo componente principal periódico. Resultados: Es posible trabajar con reconstrucciones aceptables de imágenes comprimidas en el campo de la dermatología, sin perder la calidad y características que permitan llegar a un diagnóstico correcto. Además, este logro permite clasificar correctamente muchas enfermedades sin miedo a equivocarse. Conclusiones: Con el método presentado se propone el uso de una técnica robusta de compresión de imágenes médicas que podría ser de gran utilidad en el campo de la salud. Las imágenes permiten el diagnóstico de enfermedades como la COVID-19 en pacientes paucisintomáticos, con cuya compresión se minimiza su peso sin perder la calidad, lo que facilita su uso y almacenamiento.

Enfermedad de Kawasaki. Reporte de un caso infrecuente en el adulto / Kawasaki disease. Report of a rare case in an adult

RESUMEN La enfermedad de Kawasaki forma parte de un grupo heterogéneo de afecciones de baja frecuencia que se caracterizan por la presencia de inflamación y necrosis de la pared vascular, que generan diversas manifestaciones clínicas y patológicas, las cuales comprometen medianos vasos, y que afectan principalmente a la población pediátrica. Presentamos el caso de un hombre de 36 arios de edad, sin antecedentes patológicos previos, con cuadro febril de 4 días de evolución asociado a cefalea, náuseas y odinofagia, con posterior aparición de múltiples lesiones maculopapulares generalizadas, las cuales se resolvieron con descamación en pulpejos, palmas y plantas. Se documenta conjuntivitis no supurativa bilateral, además de compromiso de la mucosa oral y los labios. La biopsia de piel reportó vasculitis linfocítica asociada a compromiso renal, hepático y cardiaco (miocardiopatía dilatada con fracción de eyección deprimida); se configuró el diagnóstico de enfermedad de Kawasaki completa del adulto con manifestaciones atípicas. Recibió tratamiento con metilprednisolona, ácido acetilsalicílico 100mg/día, una dosis única de inmunoglobulina IgG intravenosa 2 g/kg y terapia dialítica interdiaria, logrando una recuperación completa.

ABSTRACT Kawasaki disease is part of a heterogeneous group of low frequency diseases that are characterized by the presence of inflammation and necrosis of the vascular wall, generating various clinical and pathological manifestations, which compromise medium vessels, and mainly affecting the pediatric population. The case is presented of a 36-year-old man with no relevant past medical history, with a febrile episode of 4 days of onset, together with headache, nausea, and odynophagia with subsequent onset of multiple generalized maculopapular lesions. These resolved with subsequent desquamation of fingers, palms and soles of feet. Non-suppurative bilateral conjunctivitis is documented, as well as involvement of oral mucosa and lips. Skin biopsy reported lymphocytic vasculitis, associated with renal, hepatic and cardiac involvement (dilated cardiomyopathy with depressed ejection fraction). A diagnosis of complete adult Kawasaki disease with atypical manifestations was established. He was treated with methylprednisolone, acetylsalicylic acid 100 mg per day, and a single dose of intravenous IgG immunoglobulin 2 g/kg, and daily dialysis therapy to achieve complete recovery.

A study on epidemiological and clinical characteristics of measles patients admitted to Sir Ronald Ross institute of tropical and communicable diseases, Hyderabad, India

Background: Measles is an acute infectious exanthematous disease of childhood caused by paramyxovirus. With increase in immunization coverage levels, the intensity of measles outbreak has decreased in the country. In some parts of India, measles is still a major cause of morbidity and childhood mortality. Objective of the study was to determine the epidemiological and clinical characteristics of patients with macular/maculo-papular rash.Methods: A cross sectional record based retrospective study was carried out at Sir Ronald Ross institute of tropical and communicable diseases, Hyderabad. All the cases admitted in year 2016 with history of fever and macular/maculo-papular rash were included in the study. The study was carried out for 2 months.Results: A total of 639 cases were admitted to infectious disease hospital during the year 2016 with history of fever and rash. The mean age of study population was 6.08±4.9 years. Around 43.7% of cases were in the age group of 1–5 years. The disease was slightly higher among boys (52.3%) as compared to girls (47.7%). Amongst the clinical features, fever and rash were seen in 100%, coryza in 80%, and conjunctivitis in 63.3% of study population.Conclusions: Majority of the children suffering from measles was not vaccinated and the most common reason for failure to immunize children was lack of awareness. There is a need to increase awareness about importance of measles immunization to reduce under five mortality.

An observational study to monitor cutaneous adverse drug reaction profile in Dermatology Department of tertiary care teaching hospital

Background: Incidence of cutaneous adverse drug reactions (CADRs) in developed countries is 1 to 3% and in developing countries, it is much higher i.e. 2 to 6%. 1 in 1000 hospitalized patients will develop severe cutaneous adverse reaction. Maculopapular rash represents majority of cutaneous drug reaction followed by urticaria. Most frequently elicited CADRs are associated with antimicrobials and NSAIDs. This study was designed to monitor Cutaneous adverse drug reaction profile of tertiary care teaching hospital.Methods: This is a prospective observational study of 6 months� duration to monitor cutaneous adverse drug reactions in dermatology department of tertiary care teaching hospital. CADRs were analysed with respect to demographic details, suspected drugs and type of reaction. Causality assessment is by Naranjo algorithm. Data is represented in tables and graphs. Data is analyzed in Microsoft excel 2007.Results: Total 57 cases of cutaneous adverse drug reactions were reported. Among them, 57.9% were in males and 42.1% were in females. Majority of CADRs were due to antiretroviral drugs (38.5%) followed by antibacterial (28%) and antiepileptics (14%). Maculopapular rash is most common CADR (35%). Causality of 74% CADRs were probable according to Naranjo algorithm.Conclusions: CADRs are more commonly associated with antiretroviral therapy (ART), antibacterial drugs and antiepileptic drugs. In case of ART, antiepileptic drug and drugs used in chronic illness compliance plays a major role in the success of therapy. Adverse drug reactions lead to problem of non compliance and failure of therapy. Cutaneous adverse reactions like FDE heal with hyper pigmentation leads to cosmetic problem. Stevens Johnson syndrome (SJS) is life threatening that requires prompt withdrawal of drug and intensive medical management. Many drugs are available without prescription in India leading to problem of misdiagnosis of CADRs. So, data obtained from this study helps in proper diagnosis and treatment of CADRs.

Drug eruption by antihistamine mistaken for chronic urticaria in a child / 소아과

Although rare, antihistamines can cause adverse effects, including drug-induced eruptions or anaphylaxis. A 4-year-old child visited the pediatric department of a hospital for skin eruptions after administration of antihistamines, (e.g., ucerax [hydroxyzine] or leptizine [levocetirizine]), for cholinergic rashes; he did not have pruritus. Skin prick, intradermal, and drug provocation tests were performed to determine the relationship between the antihistamines and eruptions. Levocetirizine induced wheals in the skin prick test and a rash in the oral drug provocation test. In contrast, ketotifen induced no reaction in the skin prick test but showed a positive reaction in the oral provocation test. Our case report highlights that children can experience the same types of adverse reactions as seen in adults, and cross-reactivity between various antihistamines can occur.

Trastuzumab induced radiation recall dermatitis: an interesting case

Radiation recall dermatitis (RRD) is the appearance of skin reactions in previously irradiated skin which is triggered by the administration of certain drugs. Surgery, chemotherapy, and radiotherapy are the mainstay of treatment in breast cancer. RRD induced by trastuzumab has been rarely reported in India. This is a case report of a 56-year-old woman presented to the medical oncology outpatient department of our hospital with breast lump, and she was diagnosed to have human epidermal growth factor receptor 2 (HER-2/neu) positive invasive ductal carcinoma of left breast of stage T2N3cM0. She was treated with neoadjuvant chemotherapy, and she underwent modified radical mastectomy with axillary lymph node dissection. The treating oncologist was planned to start on adjuvant chemotherapy with injection trastuzumab for every four weeks, for 15 cycles. Patient received first dose of injection trastuzumab (450 mg) intravenously in the right (contralateral) arm and developed painful, swollen, erythematous blisters, and maculopapular rashes following the sharp linear borders of her previous radiation fields. She was reviewed by the medical oncologist and diagnosed as a rare case of RRD and treated with topical betamethasone cream. Causality assessment for RRD to trastuzumab was done using Naranjo and WHO-UMC scale and found to be in the category of probable and probable/ likely respectively.

Ofloxacin-induced maculopapular rash in the infant

Adverse drug reactions (ADRs) are a major cause of morbidity and mortality in countries having limited healthcare resources. The ofloxacin is an antimicrobial used for treating several bacterial infections. The ofloxacin, belonging to quinolone group of drugs, is bactericidal and acts by inhibition of bacterial DNA gyrase. Among the adverse drug reaction of ofloxacin, skin rashes are rare. An ofloxacin-induced maculopapular rash is the unique rare condition in the infant. The present case report was assessing the causality in ofloxacin induced maculopapular rash in the infant. Naranjo Adverse Drug Reaction Probability Scale and World Health Organization and Uppsala Monitoring Centre (WHO-UMC) system for standardized case causality assessment were used for assessing the causality. According to the Naranjo and WHO-UMC, ofloxacin scaled as the probable/likely cause of this ADR in infant. So, authors can conclude that the ofloxacin should be used cautiously in the pediatric age group.

Cutaneous Adverse Drug Reactions in Sabah: A 3-year study between 2014 - 2016

Introduction:Cutaneous adverse drug reactions are one of the most common adverse drug reactions. Publicationson clinical correlation between cutaneous presentations and causative agents are limited among thelocal population. This study aims to determine the clinical presentations of cutaneous adverse drugreactions and the causative drugs in the local population.Methods:A retrospective, cross sectional study was conducted from the pharmacy cutaneous adverse drugreaction database from January 2014 to December 2016 in Tawau, Keningau & Queen Elizabeth (KotaKinabalu) Hospitals.Results:A total of 859 cases of cutaneous adverse drug reactions were identified. Out of these, 53.3% (n=458)were females and 46.7% (n=401) were males. The mean age was 36 years old. Majority of patients were20-29 years old (16.6%) followed by 50-59 years old (15.1%). Most of the cases were reported amongthe Chinese community (16.4%), followed by the Malay (15.9%), Dusun (14.7%) and Bajau (14.0%)populations. The most common cutaneous manifestations were urticaria and or angioedema (49%, n=421) and maculopapular rash (39.6%, n=340). Severe cutaneous adverse reactions (SCAR) constituted2.8% in total. The major causative agent was antibiotic which accounted for 55.1% (n=473), followedby nonsteroidal anti-inflammatory drugs (NSAIDs), 28.1% (n=241) and analgesics, 10.8% (n=93).Conclusion:The types of cutaneous manifestations and causative drugs in Sabah are similar to those reported inother states of the country and abroad. This study provides evidence of local cutaneous adverse drugreaction characteristics in different ethnic group.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS):A Review of 21 Cases over 7 years Period from Selayang Hospital

Introduction: DRESS is an uncommon severe cutaneous adverse drug reaction, which is under recognized. In this review, we aim to study the clinical characteristics of patients with DRESS that presented to our hospital. Methods: We conducted a retrospective analysis on the data of all the patients with DRESS from January 2006 to December 2012 in Selayang Hospital. Results: Twenty-one patients were included with median age of 33 and male to female ratio of 1:1. Allopurinol was the most frequent causative drug followed by anti-tuberculous drugs. The mean latency period was 28.6 days. All patients had macula-papular rash of which 6 progressed to erythroderma. Liver was the most frequent extra cutaneous organ involvement with median peak alanine transaminase of 746 iu/l, (range 45-3677) and median peak aspartate transaminase of 632 iu/l (range 30-3136). Six patients (28.5%) had acute liver failure. The mainstay of treatment was systemic corticosteroid. Mortality rate was 23.8%. Conclusion: DRESS is a severe cutaneous adverse drug reaction with a myriad of clinical presentation and is associated with mortality. Our series has higher mortality compared to most other reported studies, most probably due to referral bias. Early recognition is crucial.

Maculopapular rash presentation of febrile illness in an adult with Varicella zoster virus infection.

Varicella zoster usually manifests as maculopapular rash (MPR), which later progresses to vesicle. It can also manifest as MPR without progression to the vesicle stage. This atypical manifestation is more common in adults and immunocompromised patients. A 30‑year‑old female presented with high‑grade fever and rash over face and body for 5 days. She was diagnosed to have Varicella zoster virus (VZV) infection by positive VZV immunoglobulin M enzyme‑linked immunosorbent assay and polymerase chain reaction. We present this case to increase awareness among clinicians on the atypical manifestations of VZV and prevent complications by early diagnosis.

Microcefalia e Zika Vírus: características e associações / Microcephaly and Zika Virus: clinical features and associations / Microcefalia y Virus Zika: características y asociaciones

Objetivo: Discutir a associação entre microcefalia e a infecção materna por Zika Vírus. A microcefalia é o tamanho da cabeça menor do que o esperado em comparação com bebês do mesmo sexo e idade. Entre as causas conhecidas, estão as infecções congênitas. O aumento de casos entre outubro e novembro de 2015 no nordeste brasileiro, que coincidiu com a presença da circulação de novo vírus no país, em maio do mesmo ano, criou a hipótese de associação entre a microcefalia e a infecção materna durante a gravidez. O Zika Vírus é um arbovírus similar ao da Febre Amarela e da Dengue, transmitido principalmente através da picada do Aedes aegypti. A provável transmissão por relação sexual e transfusão de sangue, além de outros vetores como o Aedes albopictus e possivelmente até o pernilongo (Culex sp) aumentam a necessidade de cuidados preventivos em relação à infecção. O exame para detecção viral idealmente é realizado até o quinto dia após o início dos sintomas. Sorologias ainda não são amplamente disponíveis no Brasil. Métodos: Revisão narrativa da literatura. Conclusão: A associação entre casos de microcefalia e o Zika Vírus é embasada nos relatos de relação têmporo-espacial, padrão de alterações neurológicas associado a malformações congênitas, presença do RNA viral no líquido amniótico e nos tecidos de fetos. As respostas definitivas de causalidade serão possíveis após pesquisas e disponibilidade de exames laboratoriais. As evidências até agora apoiam fortemente esta hipótese e todas as medidas preventivas devem ser estimuladas.

Objective: To discuss the association between microcephaly and intrauterine infection by Zika virus. Microcephaly occurs when a child is born with a head smaller than expected when compared to babies of the same sex and age. Known causes of microcephaly include congenital infections. The increase in the number of microcephaly cases in Northeast Brazil between October and November 2015, which coincided with the emergence of Zika virus in the country in May of the same year, led to the hypothesis of an association between microcephaly and intrauterine Zika virus infection. Zika is an arbovirus that is closely related to yellow fever and dengue viruses. Aedes aegypti mosquitoes are the primary vector of transmission. Possible transmission through sexual contact and blood transfusion, as well as the implication of other vectors, such as Aedes albopictus and even Culex sp increases the need for preventive action. The test for viral detection is ideally performed before the 5th day following the onset of symptoms. Serology tests are not yet widely available in Brazil. Methods: We performed a narrative literature review. Conclusion: The hypothesis of an association between microcephaly and Zika virus is based on reports of spatial/temporal relationship, pattern of neurologic alterations associated with congenital malformations, and findings of viral RNA in amniotic fluid and fetal tissue. Definitive conclusions about the causality can only be reached after further research and availability of laboratory tests. The current evidence strongly supports the association between microcephaly and Zika infection, and all preventive measures must be stimulated.

Objetivo: Discutir las asociaciones entre microcefalia e infección materna por Virus Zika. La microcefalia es el tamaño de la cabeza menor de lo esperado en comparación con los bebés del mismo sexo y edad. Entre las causas conocidas están las infecciones congénitas. El aumento de casos entre octubre y noviembre de 2015 en el nordeste de Brasil, que coincidió con la presencia de la nueva circulación del virus en el país en mayo del mismo año, creó la hipótesis de asociación entre la microcefalia y la infección de la madre por Virus Zika durante el embarazo. El virus Zika es un arbovirus similar al dengue y la fiebre amarilla. El virus se transmite a través de la picadura del mosquito Aedes aegypti. La probable transmisión por vía sexual y por la transfusión de sangre - además de otros vectores como el Aedes albopictus y posiblemente el mosquito Culex sp - aumentan la necesidad de atención preventiva contra la infección. El cuadro clínico es benigno, autolimitado, caracterizado por erupción maculopapular asociado con otros síntomas tales como conjuntivitis, artralgia y la inflamación de las articulaciones. El examen para la detección del virus se realiza idealmente por el quinto día después de la aparición de los síntomas. Las pruebas serológicas no están ampliamente disponibles en Brasil. Métodos: Revisión de literatura. Conclusión: La asociación entre los casos de microcefalia y el virus Zika se basa en informes de patrón de relación temporo-espacial de los trastornos neurológicos asociados con malformaciones congénitas, el ARN viral presente en el líquido amniótico y tejidos de fetos. Las respuestas definitivas de causalidad serán posibles después de la investigación y la disponibilidad de pruebas de laboratorio. Hasta ahora, las evidencias apoyan firmemente esta hipótesis y todas las medidas preventivas deben ser estimuladas.

A Case of Local and Generalized Skin Adverse Reactions after Pneumococcal Vaccination / 대한피부과학회지

Pneumococcus is the most frequently encountered causative pathogen in community-acquired pneumonia in elderly patients. The pneumococcal polysaccharide vaccine (PPV23) is widely used for preventing pneumococcal diseases in adults. PPV23 is relatively safe; however, some cutaneous adverse reactions, including localized mild inflammation associated with erythema, a sensation of heat, and tenderness, have been reported. Systemic reactions such as myalgia, arthralgia, and headache have also been reported, though severe adverse reactions are rare. In the Korean literature, a case of localized toxic reaction near the injection site after pneumococcal conjugate vaccine (PCV13) administration was previously reported. However, there are no published reports of a generalized skin rash after PPV23. Herein, we report a case of PPV23-induced generalized skin rash on the face, neck, upper trunk, and both arms with a local adverse reaction at the injection site after vaccination.

HLA-A*24:02/B*51:01 haplotype and lamotrigine-induced cutaneous adverse drug reactions in Koreans

Antiepileptic drugs (AEDs) have been known to induce cutaneous adverse drug reaction (cADR), ranging from a mild maculopapular eruption (MPE) to potentially life-threatening cADRs such as Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Despite studies examining mechanisms associated with human leukocyte antigen (HLA), the association between lamotrigine (LTG)-induced cADR and HLA alleles still has room to investigate. We investigated HLA-A,-B, and -C alleles in LTG-induced cADR. The medical records of four patients with LTG-induced cADR were retrospectively reviewed. All patients were treated with LTG for epilepsy. All recovered from cADR after stopping LTG treatment and receiving intensive care. HLA-A, -B, and -C genotyping was performed in all four patients using a PCR-sequence-based typing (SBT) method. Two patients had SJS, and the other two had MPE due to LTG. The range of latency to cADR after the initial LTG dose was 19–42 days. Two patients experienced cross-reactivity with other aromatic or new AEDs. Expression of the HLA-A*24:02/B*51:01 haplotype was detected in three (75%) patients with LTG-induced cADR. The other patient carried homozygous HLA-B*58:01 alleles. The results suggest that Korean individuals with the HLA-A*24:02/B*51:01 haplotype may be susceptible to LTG-induced cADR. Further investigations are necessary to confirm these findings.

Phenytoin/albendazole induced exanthematous eruptions: a case report.

Exanthematous drug eruptions, often called “drug rashes” or “maculopapular eruptions” by non-dermatologists are the most common form of cutaneous drug eruption. Cutaneous reactions are among the most common adverse effects of drugs, including penicillins, cephalosporins, sulfonamides, and allopurinol (with an incidence of up to 50 cases per 1000 new users), and particularly the aromatic amine anti-seizure medications, including carbamazepine, phenytoin, and lamotrigine (with an incidence of up to 100 cases per 1000 new users). Phenytoin is a hydantoin derivative anticonvulsant drug used primarily in the management of complex partial seizures and generalized tonic-clonic seizures. Albendazole is a benzimidazole medication used for the treatment of a variety of parasitic worm infestations. Carbamazepine and phenytoin are among the most common causes of antiepileptic drug-related cutaneous adverse reactions. Manifestations range from a mild erythematous maculopapular rash to life-threatening Stevens-Johnson syndrome and toxic epidermal necrolysis. Albendazole induced rashes and urticaria have been reported in less than 1% of the patients. Here we present the case of a 12-year-old male patient who came to the dermatology outpatient department with complaints of itching and maculopapular eruptions all over the body. The patient gave a history of taking tablet phenytoin and tablet albendazole for neurocysticercosis since 1-week. There was no fever or any other systemic manifestations. There was no history of any other drug intake. A diagnosis of phenytoin/albendazole induced exanthematous eruptions was made. Both the medications were discontinued, and the patient was advised to take syrup sodium valproate 200 mg BD. For the rashes and itching, the patient was advised to take tablet hydroxyzine HCl 10 mg OD, tablet prednisolone and tablet levocetirizine for 5 days. Improvement was seen and the itching reduced. Rechallenge was not done. In this event, casualty assessment using Naranjo adverse drug reaction probability scale revealed that phenytoin/albendazole were probable causes for the adverse drug reaction.

Ofloxacin induced hypersensitivity reaction.

Ofloxacin is a commonly used antimicrobial agent to combat various infections. The adverse profile of quinolones includes gastrointestinal symptoms, which are the most frequent, neuropsychiatric symptoms, hematologic abnormalities are less common. We report a rare case of ofloxacin induced hypersensitivity reaction in a 57 year old female patient with complaints of rashes over the axilla, upper limb and back, abdomen, thorax associated with exfoliation of skin all over the axilla associated with severe itching. Based on history and clinical examination patient was diagnosed as ofloxacin induced hypersensitivity reaction and was successfully treated with antihistamines and corticosteroids. Pharmacovigilance should be a part of patient care in order to reduce occurrence of adverse drug reaction and also encourage practitioners in reporting so as to gather more and more data regarding adverse drug reactions

Chloramphenicol induced maculopapular rashes.

Chloramphenicol is a broad spectrum antibiotic that acts by inhibiting protein synthesis. Though systemic use is rare, their topical preparations are commonly used. Allergic reaction due to chloramphenicol ear drops are less reported. Here, we have reported a maculopapular exanthema due to use of chloramphenicol ear drops.

Maculopapular skin rash due to amoxicillin tri-hydrate hypersensitivity reaction: a case report.

Amoxicillin tri-hydrate (AMT) is a commonly used penicillin group of antibacterial agent to combat various bacterial infections. Penicillin group of drugs are known to cause cutaneous drug eruptions as a hypersensitivity reaction. Most of the time, these eruptions are mild in nature, however, sometimes they represent the early manifestation of rare and severe drug-induced cutaneous reactions, such as; Stevens–Johnson syndrome and toxic epidermal necrolysis. Here, we report a case of maculopapular skin rash developed due to AMT hypersensitivity reaction in a 48-year-old Indian male patient. Pheniramine maleate, hydrocortisone and skin protecting lotion were prescribed to manage the situation. This case is being reported to emphasize the need for reporting of drug induced complications and their management procedures.

Decitabine Induced Localized Maculopapular Eruption.

Aims: Decitabine is a drug for the treatment of myelodysplastic syndromes and acute myeloid leukemia. It has a side-effect profile affecting many systems, including dermatologic side effects. Herein, we report a case with a maculopapular-type drug eruption due to decitabine. Presentation of Case: A 51-year-old previously healthy woman was diagnosed with myelodysplastic syndrome RAEB-1, and decitabine [20mg/m2/day/i.v (5 days with cycles repeated every 28 days)] chemotherapy was given. On the seventh day of the second treatment cycle, we diagnosed a maculopapular eruption on the front of the left arm. The patient presented with skin that was itchy, puffy, maculopapular and erythematous. The rash faded when pressed and tended to coalesce with each other, indicating a drug eruption due to decitabine. Maculopapular type drug reaction depending on decitabine was considered. The eruption improved remarkably within 10 days, and the patient's rash had disappeared by the 17th day of treatment. Discussion: Drugs occasionally induce cutaneous side effects. Ecchymosis, rash, erythema, petechiae skin lesion and pruritus have been described in decitabine’s prospectus. Maculopapular eruptions can affect all age groups. This type of eruption is common with certain drugs as well as with several diseases and medical conditions including scarlet fever, measles, rubella, secondary syphilis, parvovirus B19 and heat rash. A number of drugs may cause the appearance of maculopapular eruptions. Conclusion: Practitioners should be aware of this rare, but potentially serious, adverse event, especially as decitabine is commonly used for myelodysplastic syndromes and acute myeloid leukemia.

Clonazepam induced maculopapular rash: a case report.

Clonazepam is a benzodiazepine with prominent anticonvulsant action than other members of the group at equisedating doses. It especially blocks pentylenetetrazole-induced seizures. Other important actions include anxiolysis. Common adverse effects to Clonazepam include drowsiness and lethargy. In this submission we report a case of Clonazepam induced maculopapular rash in a 30 year old female treated for panic disorder.
