RESUMEN

BACKGROUND: Scrub typhus is a naturally occurring acute infectious disease that is primarily transmitted through the bites of chiggers or larval mites infected by Orientia tsutsugamushi (O. tsutsugamushi). Omadacycline, a novel tetracycline, exhibits potent antibacterial efficacy against both typical bacteria and atypical pathogens. However, omadacycline application in the treatment of scrub typhus remains limited. CASE SUMMARY: In the present work, we report several cases of scrub typhus, with the main clinical symptoms being fever, the formation of eschars or ulcers, local or systemic lymphadenopathy, headache, myalgia and rash. Blood samples were collected before omadacycline was administered, and O. tsutsugamushi infection was confirmed through targeted next-generation sequencing (tNGS). After two days of treatment, the patients' symptoms, including fever, were alleviated, with no adverse drug reactions. CONCLUSION: tNGS is an effective method for diagnosing scrub typhus. Omadacycline can be considered an alternative option for antiinfective therapy in patients with O. tsutsugamushi infections.

RESUMEN

Introduction: Skin necrosis following total knee arthroplasty (TKA) represents a rare, but serious complication that can lead to deep infection. In the setting of a lateral release performed during TKA, the incised retinaculum unveils a potential pathway to the joint should the superficial skin and tissue be compromised. Thus, the conventional treatment of debridement in this setting may risk infection to the joint, whereas eschar preservation may serve as a biological protective barrier to prevent infection. Case Report: We present a patient with end-stage tricompartmental knee osteoarthritis who underwent a TKA with a concomitant lateral release. The patient developed necrosis in two distinct areas measuring 14 cm × 2 cm along the length of the primary TKA incision, and 7 cm × 4 cm laterally. The patient was treated with eschar preservation, oral doxycycline, an antimicrobial silver dressing, and allowed to heal by secondary intention. The patient's skin necrosis healed fully at 12-week post-operatively, and they have had a successful TKA outcome at 5 years. Conclusion: Eschar preservation, oral doxycycline, an antimicrobial silver dressing, and allowing the wound to heal by secondary intention may represent a viable, less invasive treatment for skin necrosis following TKA with lateral release.

RESUMEN

Deep burn injuries necessitate effective debridement to promote healing and reduce complications. Traditional surgical debridement is the standard of care; however, it can lead to significant tissue loss, excessive bleeding and delayed healing. Bromelain-based enzymatic debridement offers a potential less invasive alternative that aims to selectively remove necrotic tissue while preserving viable ones. Therefore, this systematic review and meta-analysis comprehensively compares bromelain debridement versus standard care in the management of partial and full-thickness burns. Cochrane Library, Embase, and Medline were searched until May 30th, 2024 for studies comparing bromelain debridement versus standard care. R version 4.4.0 was used to pooled risk ratio and mean difference in a random-effects model. We included seven studies, comprising 484 participants, of whom 238 (49%) were treated with enzymatic debridement. Bromelain significantly reduced time to eschar removal (MD - 7.60 days 95% CI [-9.76, -5.44]; I² = 70%) in comparison with standard care. Additionally, bromelain group presented a significant reduction in the risk of surgical excision (RR 0.17; 95% CI [0.06, 0.47]; I² = 79%) and need for autografts (RR 0.40; 95% CI [0.18, 0.93]; I² = 76%) in comparison with standard group. No differences were found in behalf of time to wound closure (MD -7.64; 95% CI [-18.46]-[3.18]; I2 = 86%), nor in Modified Vancouver Scar Scale (MD -0.36; 95% CI [-0.96]-[0.23]; I2 = 0%). Bromelain-based enzymatic debridement may accelerate eschar removal and reduce the need for surgical excision and autografts, without adversely affecting wound closure time or long-term scar quality.

RESUMEN

Burn is one of the most common skin injuries and accounts for 300,000 deaths annually. Debridement and antibiotic therapy are major burn treatments, however, as debridement is not always possible and many drugs have poor penetration into necrotic tissue, permeation enhancement is acquired. Another challenge is the short duration of topically applied drugs. This study aims to address both problems by combining in-situ forming gels and microneedles. A chitosan-based in-situ forming gel of hydrocortisone was applied to human burn eschar using microneedles. The formulation was optimized using Design-Expert software. Formulation characterization was done in terms of gelling time and temperature, thermal analysis, release phenomenon, rheology, texture analysis, and stability. Finally, animal studies on mice burn wound treatment were conducted. Results showed that optimized formulation controlled the drug release, and wherever microneedle was used, drug permeation and flux increased (P-value < 0.05). In all ex-vivo and in-vivo stages, gel plus microneedle (length of 1.5 mm and application mode of 2) produced the best results concerning increased flux and faster recovery of burn eschar. In conclusion, the in-situ forming gel with appropriate texture, quality, and stability in combination with microneedle can be a good candidate for the controlled release of drugs in third-degree burn eschars.

RESUMEN

Chronic wounds typically comprise of necrotic tissue and dried secretions, often culminating in the formation of a thick and tough layer of dead skin known as eschar. Removal of eschar is imperative to facilitate wound healing. Conventional approach for eschar removal involves surgical excision and grafting, which can be traumatic and frequently leads to viable tissue damage. There has been growing interest in the use of enzymatic agents for a gentler approach to debridement, utilizing proteolytic enzymes. In this study, a purified intracellular recombinant serine protease from Bacillus sp. (SPB) and its cream formulation were employed to evaluate their ability to degrade artificial wound eschar; composed of collagen, fibrin, and elastin. Degradation was assessed based on percentage weight reduction of eschar biomass, analysis via sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), and scanning electron microscopy (SEM). Both SPB and its cream formulation were able to degrade up to 50 % artificial wound eschar, with the SPB cream maintaining its degradation efficiency for up to 24 hours. Additionally, the SPB-based cream demonstrated the ability to hydrolyze proteinaceous components of eschars individually (fibrin and collagen) as determined through qualitative assessment. These findings suggest that SPB holds promise for the debridement of wound eschar.

RESUMEN

Background: Scrub typhus (ST) is endemic in Fukushima, with the largest number of cases reported in Japan from 2009 to 2010. Although ST is highly treatable, its atypical clinical presentation impedes diagnosis, causing delays in treatment. Methods: We review the clinical features of ST in adults from 2008 to 2017 at Ohta Nishinouchi General Hospital in Fukushima, Japan. Results: Fifty-five cases (serotype Karp 24, Irie/Kawasaki 21, Hirano/Kuroki 10) of ST were confirmed via serology based on elevated immunoglobulin (Ig)M and IgG and polymerase chain reaction positivity of eschar samples. The mean age was 69 years, and 64% were female. The case fatality rate was 1.8% (1/55). Approximately 70% of cases (38/55) were not diagnosed as ST upon the initial clinic visit. Inappropriate use of antibiotics was identified in 22% of cases (12/55). In terms of atypical clinical features, 1 or more of the manifestations, fever, rash, and eschar, was absent in 31% of cases (17/55). Approximately 11% of cases presented without eschar (6/55; Karp 1, Irie/Kawasaki 1, Hirano/Kuroki 4). Moreover, severe complications were observed with shock and disseminated intravascular coagulation in 7% of cases (4/55), Thus, while 53% of cases presented with the typical triad (29/55), unusual complications and atypical features occurred in 40% (22/55). Conclusions: Diagnosis of ST becomes clinically challenging in the absence of typical features. In Fukushima, an endemic area of ST, an atypical presentation involving multisystem disease is common.

RESUMEN

Coma blisters, or coma bullae, are lesions often seen in the setting of impaired consciousness. Most commonly associated with drug-induced comas, coma bullae have been repeatedly linked to central nervous system (CNS) depressing agents, such as opiates. These lesions are believed to develop due to a complex multifactorial process involving external pressure on the skin, which leads to hypoxia and eventual death of eccrine sweat glands. In addition, the vasoactive and inflammatory properties of CNS depressing agents may play a role in this process. Come bullae usually develop on pressure points 48-72 hours after the onset of impaired consciousness and are self-limiting. We present the case of a 68-year-old male who was brought to the emergency department after being found unresponsive on the street. The urine drug screen was positive for cocaine and fentanyl. The initial examination showed several large, non-tender bullae on his scalp that continued to expand over two days. He subsequently developed similar lesions on his thighs, right shoulder, and knuckles. Dermatology was consulted and clinically diagnosed the patient with coma bullae, likely attributed to his altered consciousness and opiate use. Notably, more violaceous bullae were found on the bilateral lower extremities, with dermatology suspecting additional vasculitic features related to concurrent opiate and cocaine use. Skin biopsy and aspiration were deferred to avoid the risk of infection, and the patient was discharged per dermatology's recommendations for no immediate intervention. He continued to follow with wound care for the next six months, with most of the bullae healing. However, eschars developed over the scalp and left lower extremity, requiring debridement by general surgery. This case report underscores a unique manifestation of coma bullae. Unlike typical presentations localized to pressure-dependent areas and appearing after two to three days of unconsciousness, our patient exhibited blisters in atypical sites with associated vasculitic features. Moreover, the development of eschars over time may be linked to ongoing vasoactive drug use, reperfusion injury, and social determinants of health. This case highlights the complex and multifactorial nature of coma bullae, emphasizing the challenges in wound care and management despite their expected self-resolution.

RESUMEN

Scrub typhus, a tropical rickettsial infection, can have various neurological manifestations. Here, we present the case of an otherwise healthy 19-year-old female who presented to the emergency department with fever, headache, and diplopia. On examination, she was found to have bilateral sixth nerve palsy and bilateral papilledema. Initial unenhanced CT of the brain and CT venogram were unremarkable. The cerebrospinal fluid study was normal. Later, bloodwork revealed high titers of Orientia tsutsugamushi antibody. A thorough physical examination revealed no evidence of any eschar. She was treated with doxycycline and had significant clinical improvement with partial recovery of bilateral lateral rectus function. We want to highlight the importance of maintaining a high index of suspicion for atypical neurological presentations of scrub typhus.

RESUMEN

Background and Objectives: Burn surgery on the hands is a difficult procedure due to the complex anatomy and fragility of the area. Enzymatic debridement has been shown to effectively remove burn eschar while minimizing damage to the surrounding tissue and has therefore become a standard procedure in many burn centers worldwide over the past decade. However, surprisingly, our recent literature review showed limited valid data on the long-term scarring after the enzymatic debridement of the hands. Therefore, we decided to present our study on this topic to fill this gap. Materials and Methods: This study analyzed partial-thickness to deep dermal burns on the hands that had undergone enzymatic debridement at least 12 months prior. Objective measures, like flexibility, trans-epidermal water loss, erythema, pigmentation, and microcirculation, were recorded and compared intraindividually to the uninjured skin in the same area of the other hand to assess the regenerative potential of the skin after EDNX. The subjective scar quality was evaluated using the patient and observer scar assessment scale (POSAS), the Vancouver Scar Scale (VSS), and the "Disabilities of the Arm, Shoulder, and Hand" (DASH) questionnaire and compared interindividually to a control group of 15 patients who had received traditional surgical debridement for hand burns of the same depth. Results: Between January 2014 and December 2015, 31 hand burns in 28 male and 3 female patients were treated with enzymatic debridement. After 12 months, the treated wounds showed no significant differences compared to the untreated skin in terms of flexibility, trans-epidermal water loss, pigmentation, and skin surface. However, the treated wounds still exhibited significantly increased blood circulation and erythema compared to the untreated areas. In comparison to the control group who received traditional surgical debridement, scarring was rated as significantly superior. Conclusions: In summary, it can be concluded that the objective skin quality following enzymatic debridement is comparable to that of healthy skin after 12 months and subjectively fares better than that after tangential excision. This confirms the superiority of enzymatic debridement in the treatment of deep dermal burns of the hand and solidifies its position as the gold standard.

RESUMEN

Since 1970 surgeons have managed deep burns by surgical debridement and autografting. We tested the hypothesis that enzymatic debridement with NexoBrid would remove the eschar reducing surgery and achieve comparable long-term outcomes as standard of care (SOC). In this Phase 3 trial, we randomly assigned adults with deep burns (covering 3-30% of total body surface area [TBSA]) to NexoBrid, surgical or nonsurgical SOC, or placebo Gel Vehicle (GV) in a 3:3:1 ratio. The primary endpoint was complete eschar removal (ER) at the end of the debridement phase. Secondary outcomes were need for surgery, time to complete ER, and blood loss. Safety endpoints included wound closure and 12 and 24-months cosmesis on the Modified Vancouver Scar Scale. Patients were randomized to NexoBrid (n = 75), SOC (n = 75), and GV (n = 25). Complete ER was higher in the NexoBrid versus the GV group (93% vs 4%; P < .001). Surgical excision was lower in the NexoBrid vs the SOC group (4% vs 72%; P < .001). Median time to ER was 1.0 and 3.8 days for the NexoBrid and SOC respectively (P < .001). ER blood loss was lower in the NexoBrid than the SOC group (14 ± 512 mL vs 814 ± 1020 mL, respectively; P < .0001). MVSS scores at 12 and 24 months were noninferior in the NexoBrid versus SOC groups (3.7 ± 2.1 vs 5.0 ± 3.1 for the 12 months and 3.04 ± 2.2 vs 3.30 ± 2.76 for the 24 months). NexoBrid resulted in early complete ER in >90% of burn patients, reduced surgery and blood loss. NexoBrid was safe and well tolerated without deleterious effects on wound closure and scarring.

RESUMEN

This retrospective study examines the implementation of Nexobrid, an enzymatic debriding agent developed from bromelain, for burn debridement in a major Italian burn center. With previous research showing encouraging results for Nexobrid in terms of reducing the need for surgical intervention and faster eschar removal, the current study aims to add to the growing body of evidence regarding its potential benefits and limitations. The patient database was utilized to identify patients who received Nexobrid treatment between October 2019 and June 2023. A retrospective analysis was conducted to gather demographic information, burn causes, procedural details, and patient outcomes. Of the 30 patients treated with Nexobrid, 10% did not require further surgical intervention, showcasing Nexobrid's potential to improve patient outcomes. However, over 80% of patients still required additional surgical intervention, demonstrating that Nexobrid's effectiveness varies across patients and should be considered a tool rather than a definitive solution in burn wound management. A few patients developed complications, and about 10% of patients succumbed to systemic complications. The study results reveal both the potential benefits and limitations of using Nexobrid in burn debridement. While it successfully eliminated the need for further surgical intervention in a small percentage of patients, the majority still required additional surgical procedures. These findings not only highlight Nexobrid's role as a tool in burn wound management but also point toward the discrepancies with previous studies. The authors suggest future research should include randomized controlled trials, direct comparisons between Nexobrid and traditional debridement methods, and studies incorporating larger and more diverse patient groups.

RESUMEN

Aim: A series of cases have been presented involving the oral cavity focusing on the presentation, diagnosis and treatment of mucormycosis that can form a basis for successful therapy. Background: The management of severe coronavirus disease (COVID-19) in conjunction with comorbidities such as diabetes mellitus, hematological malignancies, organ transplants, and immunosuppression have led to a rise of mucormycosis which is an opportunistic infection. Cases Description: The various forms that have been enlisted till date are rhino-cerebral, rhino-orbital, gastrointestinal, cutaneous, and disseminated mucormycosis. From the dentistry and maxillofacial surgery perspective, the cases depicting extension of mucormycosis into the oral cavity have been less frequently recorded and thus, require a detailed study. The patients that reported to our private practice had non-tender swelling, draining sinuses and mobility of teeth. A similarity was observed in the clinical signs both in osteomyelitis and mucormycosis. Thus, a histopathological examination was used to establish the definitive diagnosis. Conclusion: Mucormycosis is a life threatening pathology that requires intervention by other branches to make an early diagnosis and commence the treatment. The characteristic ulceration or necrosis is often absent in the initial stage and thus, histopathological examination and radiographic assessment are required to formulate a definitive diagnosis. Early intervention is a necessity to avoid morbidity. The treatment involves surgical debridement of the necrotic infected tissue followed by systemic antifungal therapy. Mucormycosis has recently seen a spike in its prevalence, post the second-wave of coronavirus pandemic in India. It was seen commonly in patients with compromised immunity, diabetes mellitus, hematological malignancies, or on corticosteroid therapy. Mucormycosis invading the palate mostly via maxillary sinus has been less frequently described. In the post-COVID era the features associated with mucormycosis involving oral cavity, should warrant a possible differential diagnosis and managed appropriately. (AU)


Objetivo: Apresentar uma série de casos com enfâse na apresentação, diagnóstico e tratamento da mucormicose oral, assim como uma revisão sistemática que sirva como base para estabelecimento de terapias de sucesso. Introdução: A forma severa da infecção por coronavirus (COVID-19) associada a diabetes mellitus, doenças hematológicas malignas, transplante de órgãos e imunossupressão levaram a um aumento das infecções oportunistas de mucormicose. Descrição dos Casos: As diversas apresentações clínicas que foram descritas até o momento são a rinocerebral, rino-orbital, gastrointestinal, cutânea e mucormicose disseminada. No que concerne a odontologia e a cirurgia maxillofacial, os casos que apresentam extensão de mucormicose para cavidade oral tem sido menos reportados e assim requerem mais estudos. Os pacientes que compareceram a nossa clínica apresentavam aumento de volume endurecido, drenagem de fluidos dos seios maxilares e mobilidade dentária. Clinicamente tanto a osteomielite quanto a mucormicose apresentaram-se de forma semelhante. Assim, análise histopatológica foi utilizada para estabelecimento do diagnóstico definitivo. Conclusão: A mucormicose é uma patologia grave que requer intervenção precoce para estabelecimento do tratamento. A ulceração e necrose características usualmente estão ausentes nos estágios iniciais da lesão, assim análise histopatológica e radiográfica são necessárias para o diagnóstico final. Intervenção precoce é necessária para diminuir a morbidade. O tratamento envolve o debridamento cirúrgico da área necrosada seguida de terapia antifúngica sistêmica. Recentemente, houve um aumento nos casos de mucormicose, após a Segunda onda da pandemia de COVID-19 na índia. Os casos acometiam principalmente pacientes imunocomprometidos, com diabetes mellitus, doenças hematológicas malignas e em uso de corticosteróides. A mucormicose invadindo o palato pelos seios maxilares foi raramente descrita. Na era pós-COVID a mucormicose envolvendo a cavidade oral deve entrar no painel de diagnósticos diferenciais para que o tratamento adequado possa ser instituído precocemente.(AU)

RESUMEN

A 17-year-old female patient presented to us with complaints of diffuse swelling in her left upper eyelid with preauricular lymphadenopathy for three days. She was diagnosed with a case of hordeolum externum and was treated on the same line. However, during follow-up, she developed a mild- to moderate-grade fever, which did not subside with treatment. On further investigation, her IgM rapid ELISA for Scrub typhus was positive, which was further confirmed by the Weil-Fellix test (OXK=1:360). She was treated with systemic doxycycline. Within a week, her fever returned to normal baseline, with resolution of local eye lid swelling, and her black scab was also gone. We have reported a case of scrub typhus as a rare manifestation with lid swelling and subsequently eschar formation on the upper eye lid. The patient was promptly treated with oral antibiotics without any morbidity.

RESUMEN

Scrub typhus is an infectious disease caused by Orientia tsutsugamushi, a bacterium within the family Rickettsiaceae. The clinical symptoms are usually acute and are characterized by fever, eschar formation or ulceration, local or generalized lymphadenopathy, and rash. Because of the extensive damage to small blood vessels throughout the body, scrub typhus can involve multiple systems and organs, causing damage to the respiratory, digestive, and nervous systems and inducing kidney and liver dysfunction. Death can occur in severe cases. We herein report two cases of scrub typhus with liver damage and intracranial infection. Among patients with scrub typhus, the risk of death is significantly higher in those who develop liver injury and intracranial infection. However, there are few reports on the treatment of patients with liver injury and intracranial infection caused by scrub typhus, and relevant treatment experience is thus lacking. Our clinical case report helps to fill the knowledge gap in this area.

RESUMEN

Scrub typhus is an acute febrile bacterial illness and has a high mortality if left untreated. It is caused by bacterium called Orientia tsutsugamushi which is transmitted to humans as zoonosis by bite of chigger mites that are infected by the bacterium. The diagnosis is based on clinical features and specific laboratory tests. Treatment of Scrub typhus is done with antibiotics and symptoms management. This report is a case of a 24-year-old female febrile patient who presented with complications of Scrub typhus due to missed diagnosis at Primary Health Centre and managed at district hospital. This case report highlights the challenges faced by health workers in management of acute febrile illness in a diagnosis-constrained setting.

RESUMEN

Background: The effect of artificial highly concentrated carbon dioxide bathing on heat-press-injured wounds has been clinically observed. Case presentation: A 46-year-old male patient with a heat press injury of the right palmar region achieved complete necrotic tissue removal and sufficient granulation of the skin graft by continuous hand bathing in a solution containing highly concentrated carbon dioxide for four weeks. The patient successfully underwent a full-thickness skin graft from the plantar to the palmar region, and his right hand function improved to the extent that it did not interfere with daily life. Conclusions: Heat press injuries are often refractory to treatment owing to the synergistic effects of heat and crush injuries. Highly concentrated carbon dioxide bathing has long been known to increase skin and muscle blood flow, and its clinical applications in ischemic limbs, skin ulcers, and osteomyelitis have already been reported. In this case, the results suggest an effect of improved blood flow leading to maturation of the graft bed at the heat-press injury site. Lay Summary: Highly concentrated carbon dioxide bathing is not only clinically applicable to ischemic extremities, skin ulcers, and osteomyelitis, due to increased cutaneous and muscular blood flow, but also to the reliable debridement of heat press injury wounds and the granulation of graft beds. We successfully used this novel combination of procedures to establish a graft bed with a good blood flow despite the deep heat press injury occurring in the palmar region, leading to an excellent functional recovery. The cost per procedure is low, at about $1(USD), making it a wound care option that should be considered from a healthcare economic perspective.

RESUMEN

Scrub typhus (ST) is an acute focal infectious disease that is caused by Orientia tsutsugamushi. The Asia-Pacific region is an area of relatively high incidence. There is a high incidence in China, principally owing to the disease being endemic in the south of the country. The main source of ST infection is rats, which act as reservoirs of infection after being bitten by the chigger mite, and the human population is generally susceptible to the disease. ST can be controlled and treated successfully if antibiotics are administered in a timely manner. However, because it does not have a specific clinical manifestation, it is difficult to distinguish ST from other febrile diseases in clinical practice. Therefore, rapid diagnostic methods are still needed to help clinicians make a timely diagnosis. Here, we share three cases of patients with ST who experienced hemorrhage, but did not have typical skin lesions, such as eschar and ulcer, early in the course of their disease, and review the relevant literature regarding ST. We conclude that clinicians should pay attention to the risk of hemorrhage associated with this disease, and emphasize the importance of making an early diagnosis.

RESUMEN

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi, a Gram-negative bacillus, commonly occurring in the Asia-Pacific region. It is transmitted to humans by the bite of an infected Leptotrombidium mite and the bacterium causes endothelial dysfunction resulting in widespread vasculitis and the possible development of thrombocytopenia, meningitis, acute respiratory distress syndrome, and infrequently, myocarditis. Early diagnosis and prompt treatment are crucial in managing scrub typhus. Here, we present four cases of scrub typhus with a comprehensive literature review. This study highlights the significance of considering scrub typhus as a possible diagnosis in patients of all ages from endemic regions who exhibit symptoms such as fever, thrombocytopenia, or transaminitis, even in the absence of typical clinical features. Two cases exhibited the characteristic lesion of eschar at the site of mite feeding. One case involved a middle-aged woman who was diagnosed with typhus-induced myocarditis with left ventricular dysfunction. Another case involved a 23-day-old neonate with poor feeding and seizures, who was diagnosed with late-onset sepsis with meningitis. Scrub typhus was confirmed in all cases using a positive qualitative IgM ELISA. However, it is preferred to use paired (ELISA before and after antibiotic therapy) or quantitative titers for confirmation. Healthcare providers must consider the patient's exposure history and clinical presentation to diagnose and treat scrub typhus promptly.

RESUMEN

Background Scrub typhus is an important cause of acute febrile illness in children. It is one of the re-emerging infections in the Asia Pacific region. It is caused by the gram-negative bacteria Orientia tsutsugamushi and is spread by the bite of trombiculid mites. The initial symptomatology is nonspecific with fever, headache, vomiting, etc. The presence of eschar is said to be pathognomic. It is a systemic illness, and vasculitis is the basic pathogenic mechanism. Materials and methods A retrospective observational study was conducted in two medical colleges and associated hospitals of western Uttar Pradesh (UP) and Rajasthan, India. Case files of 21 confirmed cases of scrub typhus admitted from April 2021 to October 2022 were reviewed. Scrub typhus was suspected in children with acute undifferentiated fever, and suggestive signs and symptoms were confirmed serologically with IgM enzyme-linked immunoassay (ELISA). Demographic and clinical details were noted. Results During the study period, a total of 335 cases of acute undifferentiated fever were seen, and 6.2% of them were diagnosed as having scrub typhus infection on detailed investigation. The most common symptom was fever in 100% of them, vomiting in 57.1%, abdomen pain in 42.8%, and diarrhea in 19%. Maculopapular, erythematous rash was present in 19% of cases. None of the patients had eschar. Microvascular leakage was the main complication in 28.5%. Unusual complications seen were empyema and valvulitis in 4.7% of patients. Conclusion Scrub typhus is also seen in urban setups and in dry arid areas like Rajasthan and North West UP. So, relevant investigations should be a part of the evaluation in pediatric patients with acute undifferentiated fever. Eschar can be absent, and empyema and valvulitis are some uncommon complications. A high degree of suspicion and early diagnosis are essential as an undiagnosed infection is rapidly fatal.

RESUMEN

Due to overlapping clinical features, scrub typhus infection may be missed in presence of dengue. Concurrent infection with those two pathogens is rare and creates a diagnostic dilemma. We present a case of a 65-year-old male who was admitted with a high-grade fever and maculopapular rash. A complete hemogram revealed thrombocytopenia with raised hematocrit and positive diagnostic tests for dengue. The patient was treated conservatively with intravenous fluids and antipyretic medications in response to which the hematocrit improved, and the rash disappeared. But fever with thrombocytopenia continued to persist. On further clinical examination, a small eschar was noted on his abdomen. Doxycycline was started upon which the fever subsided, and thrombocytopenia improved. This case illustrates the importance of early recognition of coinfection in unremitting febrile illness in tropical countries to prevent potentially dangerous complications.
