RESUMEN

Introduction/Rationale: Tuberculosis remains a major public health issue. It is an opportunistic pathology, very common in HIV-immunocompromised persons, classifying it at the WHO stage 4. Ear tuberculosis remains a rare and under-diagnosed clinical form. We report here a case of ear tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed person on triple antiretroviral therapy aged 32 years hospitalized in Bamako (Mali) to discuss the diagnostic and therapeutic difficulties posed by this rare localization. Description of the case: The patient had a chronic productive cough, otalgia and right chronic purulent otorrhea. The search for acid-resistant bacilli was positive for direct examination in gastric casing fluid and swabbing of the ear pus, confirming the diagnosis of tuberculosis. Anti-tuberculosis treatment instituted for 6 months associated with adjuvants resulted in complete healing of the patient. Discussion/conclusion: Although rare, ear localization must be actively sought. Etiological treatment must be instituted upon confirmation of the diagnosis to avoid complications and sequelae.

RESUMEN

A clinical report of otomyiasis in a 1-year-old girl is reported. A III instar larva of Sarcophaga sp. was microscopically identified and Sarcophaga (Liopygia) argyrostoma (Diptera, Sarcophagidae) was suspected. A molecular method targeting a fragment of the cox1 gene was used to confirm the identity of the specimen. Although myiases are not frequent manifestations in otolaryngology, they should arouse the attention of doctors, social workers and parents dealing with disabled people, the elderly and children. This contribution also highlights the need of combining microscopy and molecular tools to achieve a correct and reliable identification of the specimen/s.

RESUMEN

BACKGROUND: Rarely, Malassezia otitis presents as a painful, erosive otitis with an otic discharge containing Malassezia and neutrophils on cytology. There are no published reports of this type of suppurative Malassezia otitis (SMO). The role of Malassezia hypersensitivity in otitis is still unknown, and no association has been demonstrated with SMO. We compared Malassezia IgE levels, intradermal test and histology changes in SMO dogs with the more conventional Malassezia otitis (MO) presentation. RESULTS: Three dogs (case 1, case 2 and case 3) were diagnosed with SMO, one dog (case 4) was diagnosed with unilateral MO and unilateral SMO, and one dog (case 5) was diagnosed with MO. Only one case (case 4) with SMO/MO had a positive Intradermal Allergy Test (IDAT) and elevated IgE levels for Malassezia. Histopathology findings from SMO revealed: interface dermatitis (case 1 and 3), lymphocytic dermatitis (case 2) and chronic hyperplastic eosinophilic and lymphoplasmacytic dermatitis (case 4). Histopathology findings from MO showed perivascular dermatitis (case 4 and 5). All the cases were treated successfully. CONCLUSIONS: SMO presents with a distinct clinical phenotype in comparison with conventional MO. No consistent aetiology could be isolated. In these clinical cases it is possible that previous treatments could have influenced the results. More research is needed to understand the possible aetiologies and the pathogenesis of SMO.

RESUMEN

PRACTICAL RELEVANCE: Chronic otitis can be one of the most frustrating diseases to manage for a small animal practitioner. While it occurs less commonly in the cat than the dog, it is no less challenging. The purpose of this review is to discuss the common and uncommon causes of chronic otitis in the cat within the clinical framework used for diagnosis and treatment. The focus is on diseases that affect the ear canal, rather than those restricted to the pinnae. CLINICAL CHALLENGES: Otitis is multifactorial, which complicates management. A common clinical mistake is to focus solely on treating the infection present. Only by addressing all factors will a clinician successfully control chronic otitis. For the purposes of this review, the authors have adopted the established model of separating primary, predisposing and perpetuating causes of otitis. Primary factors are those that directly cause otitis (inflammation); predisposing factors are those that put the patient at risk for development of otitis; and perpetuating factors are those that result in ongoing clinical signs of otitis or that prevent clinical resolution. AUDIENCE: This review is aimed at veterinarians who treat cats and particularly those with an interest in feline dermatology and otology. EQUIPMENT: While many practitioners rely on a hand-held otoscope, a video-otoscope can be very helpful for the diagnosis and treatment of chronic otitis. EVIDENCE BASE: This review presents up-to-date information regarding the diagnosis and treatment of chronic otitis in cats, with emphasis on the most recent peer-reviewed literature.

RESUMEN

To describe a case of a recurrent Candida tropicalis otitis externa, media and interna in a dog with an ear polyp. A 9-year-old Irish Setter was presented with 2 episodes of otitis sinistra, left-sided vestibular syndrome and Horner syndrome 7 months apart. At the first episode a benign ear polyp was extracted and Candida tropicalis cultured from the left middle ear. The neurological signs disappeared within 7 days, the Candida infection was more difficult to treat. Seven months later, a polyp was found in the ear again and cytology was consistent with Candida tropicalis. A unilateral left total ear canal ablation with lateral bulla osteotomy was performed and a middle ear culture confirmed Candida tropicalis. Treatment led to resolution of clinical signs. Candida tropicalis, an emerging pathogen, should be considered in cases of recurrent yeast otitis and may be difficult to treat.

RESUMEN

AIM: The Ethiopian primary care of sick children is provided within the integrated Community Case Management of childhood illnesses by Health Extension Workers (HEW). There is limited knowledge whether this cadre correctly assess and classify common diseases. The aim was to study their ability to correctly classify common childhood illnesses. METHODS: A survey was conducted from December 2016 to February 2017 in four regions of Ethiopia. Observations of the HEWs' assessment and classification of sick children were followed by child re-examination by a trained health officer. RESULTS: The classification by the HEWs of 620 sick children as compared to the re-examiner had a sensitivity of 89% and specificity of 94% for diarrhoea, sensitivity 52% and specificity 91% for febrile disorders, and a sensitivity of 59% and specificity of 94% for acute respiratory tract infection. Malnutrition and ear infection had a sensitivity of 39 and 61%, and a specificity of 99 and 99%, respectively. CONCLUSION: Most cases of diarrhoea were correctly classified, while other illnesses were not frequently identified. The identification of malnutrition was especially at fault. These findings suggest that a significant number of sick children were undiagnosed that could lead to absent or incorrect management and treatment.

RESUMEN

Muenke syndrome (MIM #602849), the most common syndromic craniosynostosis, results from the recurrent pathogenic p.P250R variant in FGFR3. Affected patients exhibit wide phenotypic variability. Common features include coronal craniosynostosis, hearing loss, carpal and tarsal anomalies, and developmental/behavioral issues. Our study examined the phenotypic findings, medical management, and surgical outcomes in a cohort of 26 probands with Muenke syndrome identified at the Children's Hospital of Philadelphia. All probands had craniosynostosis; 69.7% had bicoronal synostosis only, or bicoronal and additional suture synostosis. Three male patients had autism spectrum disorder. Recurrent ear infections were the most common comorbidity, and myringotomy tube placement the most common extracranial surgical procedure. Most patients (76%) required only one fronto-orbital advancement. de novo mutations were confirmed in 33% of the families in which proband and both parents were genetically tested, while in the remaining 66% one of the parents was a mutation carrier. In affected parents, 40% had craniosynostosis, including 71% of mothers and 13% of fathers. We additionally analyzed the medical resource utilization of probands with Muenke syndrome. To our knowledge, these data represent the first comprehensive examination of long-term management in a large cohort of patients with Muenke syndrome. Our study adds valuable information regarding neuropsychiatric and medical comorbidities, and highlights findings in affected relatives.

RESUMEN

Infections of the ear are a common presentation to an acute care environment. In this article, the authors aim to summarize the most common presentations, and diagnostic and treatment options for typical infections of the ear. This article is geared toward the emergency physician, urgent care provider, and primary care provider who will likely be the initial evaluating and treating provider to assist them in determining what treatment modalities can be managed in a clinic and what needs to be referred for admission or specialty consultation.

RESUMEN

Infectious coryza, caused by Avibacterium paragallinarum, is an acute respiratory disease of poultry that can result in substantial morbidity, mortality, and economic losses. In March 2017, the Turlock branch of the California Animal Health and Food Safety laboratory system encountered an unusual clinical and pathologic presentation of infectious coryza in 6 live, 29-d-old, commercial broiler chickens that were submitted for diagnostic investigation. Antemortem evaluation revealed severe neurologic signs, including disorientation, torticollis, and opisthotonos. Swollen head-like syndrome and sinusitis were also present. Histologically, severe sinusitis, cranial osteomyelitis, otitis media and interna, and meningoencephalitis were noted, explaining the clinical signs described. A. paragallinarum was readily isolated from the upper and lower respiratory tract, brain, and cranial bones. Infectious bronchitis virus (IBV) was also detected by PCR, and IBV was isolated in embryonated chicken eggs. Based on sequencing analysis, the IBV appeared 99% homologous to strain CA1737. A synergistic effect between A. paragallinarum and IBV, resulting in exacerbation of clinical signs and increased mortality, may have occurred in this case. A. paragallinarum should be considered among the possible causes of neurologic signs in chickens. Appropriate media should be used for bacterial isolation, and the role of additional contributing factors and/or complicating agents should be investigated in cases of infectious coryza.

RESUMEN

Rabbit medicine has been continuously evolving over time with increasing popularity and demand. Tremendous advances have been made in rabbit medicine over the past 5 years, including the use of imaging tools for otitis and dental disease management, the development of laboratory testing for encephalitozoonosis, or determination of prognosis in rabbits. Recent pharmacokinetic studies have been published, providing additional information on commonly used antibiotics and motility-enhancer drugs, as well as benzimidazole toxicosis. This article presents a review of evidence-based advances for liver lobe torsions, thymoma, and dental disease in rabbits and controversial and new future promising areas in rabbit medicine.

RESUMEN

Heterozygous gain of function mutations in the gene encoding p110δ subunit of PI3K have been recently associated with activated PI3K-δ syndrome (APDS), a novel combined immune deficiency characterized by recurrent sinopulmonary infections, lymphopenia, reduced class-switched memory B cells, lymphadenopathy, CMV and/or EBV viremia and EBV-related lymphoma. Here we report a dominant gain of function PIK3CD mutation (E1021K) in a patient presenting with recurrent otitis media, massive splenomegaly, and persistent EBV-viraemia. The immunological studies showed low IgA level, but normal IgM, IgG, and normal antibody response to diphtheria and tetanus toxoid vaccination. Analysis of B lymphocyte subsets revealed abnormal expansion of transitional B cells, and low percentage of switched CD27+IgD- and CD27+IgD+ memory B cells. Analysis of T cell compartment unveiled prevalence of terminally differentiated cells. This study suggests that PIK3CD gain of function mutations should be suspected despite incomplete phenotype in patients with early onset splenomegaly, persistent EBV viremia and abnormal B and T cell subsets despite normal IgG levels. Currently the optimal treatment is still debated, but prompt management can hopefully diminish incidence of severe long-lasting sequelae (i.e. bronchiectasis, ear and sinus damage).

RESUMEN

We report the case of two young brothers with Epstein-Barr virus (EBV) otomastoiditis complicated by a facial nerve paralysis. The boys, aged 7 months (patient A) and 2 years and 8 months (patient B), were diagnosed with a facial nerve paralysis House-Brackmann (HB) grade IV (A) and V (B). After unsuccessful pharmacological treatment, patient A underwent mastoidectomy and atticoantrotomy and patient B underwent a transmastoidal surgical decompression of the facial nerve. They recovered to HB grades I and II facial nerve palsy (FNP), respectively. Although rare and relatively unknown, EBV should be considered in the differential diagnosis of children with FNP of unknown cause. Surgical intervention may be a viable therapy with good recovery.

RESUMEN

Patients suffering from abducent nerve palsy are usually primary seen by a conservative medical Specialist. In most cases the ENT specialist is secondary involved for treatment. In the majority of cases abducent nerve palsy is a temporary symptom associated with neurologic or vascular diseases. Rarely inflammation, neoplasm or fracture of the skull base cause this symptom and lead to an intervention done by the ENT surgeon. This case series describes retrospectively the abducent palsy seen through the eyes of an ENT surgeon. From 2008 to 2011 15 patients suffering from abducent nerve palsy. One patient suffering from a temporal bone fracture has been treated conservatively while 14 patients needed surgery. 6 patients had a complicated inflammation of the skull base. In 7 patients skull base neoplasms were found in endoscopic surgery. In one case the underlying pathology remained unclear. 2 third of the patients that suffered from complications of inflammatory diseases completely recovered after a combined operative and conservative therapy. The patients who suffered from neoplasms of the skull base partially recovered in only one third, none, achieved full recovery. The patient with the temporal bone fracture achieved a partial recovery after 3 months. If the leading symptom of abducent palsy is caused by a severe extracranial inflammation, neoplasm or trauma an experienced skull base surgeon is mandatory. The recovery rate of abducent palsy in our case series was 60 %. The prognosis of abducent palsy in skull base inflammation is much better compared to patients with skull base neoplasm.

RESUMEN

Nasopharyngeal cancer (NPC) with mastoid recurrence is extraordinarily rare, and its development is thought to involve the Eustachian tube. We herein report a case of NPC with mastoid recurrence masquerading as acute otomastoiditis with facial paralysis in a 60-year-old man 44 months after concurrent chemoradiotherapy. The diagnosis was confirmed by exploratory tympanomastoidectomy with biopsy and Epstein-Barr-encoding region (EBER) in situ hybridization. Distant liver metastasis was detected simultaneously, and the patient underwent salvage treatment. He died 15 months later. Despite the rarity of mastoid recurrence, clinicians should be vigilant in the differential diagnosis of mastoiditis in patients with NPC after radiotherapy. Tumor biopsy and EBER in situ hybridization can aid in the accurate diagnosis of this uncommon condition.

RESUMEN

O presente estudo teve como objetivo descrever a ocorrência de otite parasitária causada por Rhabditis blumi em bovinos leiteiros de raça Gir de uma fazenda da região Norte do Brasil. Foram coletadas amostras de 42 bovinos por swab e lavado dos condutos auditivos externos (CAE). Ao exame clínico, 9,5% (4/42) dos bovinos apresentavam sintomatologia nervosa, como leve a moderada rotação da cabeça, apatia, flacidez dos lábios e ptose palpebral unilateral, alopecia das regiões da cabeça e cupim, causados pelo desconforto e prurido da região auricular, alteração na mastigação e acúmulo de alimento na cavidade oral. Adicionalmente, 71,4% (30/42) dos abovinos mostraram a presença do parasita no cerúmen dos condutos auditivos. À análise microscópica do material do saco conjuntival foi observado presença do parasita em 90% (9/10) dos bovinos avaliados. Os 30 bovinos positivos para Rhabditis spp. foram distribuídos aleatoriamente em três grupos de 10 animais: (G1) Bovinos controle, (G2) Bovinos tratados com ivermectina 1% pour on e (G3) Bovinos submetidos a lavado dos condutos auditivos externos (CAE). Cada tratamento foi repetido três vezes com intervalo de sete dias. No G1 os 10 bovinos mantiveram-se infectados durante todo o estudo. No G2 20% dos bovinos foram negativos após os dois primeiros tratamentos, porém, mostraram-se positivos na terceira avaliação. No G3 todos os bovinos mantiveram-se positivos, sendo observada apenas diminuição da carga parasitária. A identificação por análise molecular por meio de fragmentos amplificados da expansão D2/D3 do 28S rDNA confirmou a presença apenas da espécie Rhabditis blumi nos animais. Baseado nas observações clínicas, morfológicas e moleculares pode-se relatar o primeiro caso de R. blumi em bovinos da raça Gir no Estado do Pará, através da compra de animais oriundos de áreas onde a otite parasitária tem sido diagnosticada, principalmente de Minas Gerais, para formar animais mestiços (Gir x Holandês). Desta forma ressalta-se a importância do exame clínico prévio dos animais a serem transferidos para outras propriedades ou regiões. Este relato também parece ser o primeiro sobre a presença de R. blumi no saco conjuntival de bovinos. O tratamento com ivermectina no G2 não surtiu melhora clínica dos bovinos.(AU)


This study aimed to describe the occurrence of parasitic otitis caused by Rhabditis blumi in dairy cattle of the Gir race from a farm in northern Brazil. Forty-two samples were collected from cattle by swab washed from the external auditory canal (EAC). On clinical examination, in 71.4% (30/42) of the cattle the parasite was found in the cerumen of the ear canal, along with alopecia of head and hump caused by discomfort and itching of the auricular region. At microscopic analysis of material from the conjunctival sac the parasite was found in 90% (9/10) of the evaluated cattle. In addition, 9.5% (4/42) of the cattle showed nervous symptoms, such as mild to moderate rotation of the head, apathy, flaccid lips and unilateral ptosis, change in chewing and food accumulation in the oral cavity. Thirty cattle positive for Rhabditis spp. were randomly divided into three groups of 10 animals each: (G1) Cattle Control, (G2) Cattle treated with ivermectin 1% pour-on, and (G3) Cattle undergoing wash of the external auditory canal (EAC). Each treatment was repeated three times with intervals of seven days. In G1, 10 cattle remained infected throughout the study. In G2, 20% of the cattle were negative after the first two treatments, however were positive at the third evaluation. In G3, all cattle remained positive, but with decrease in parasite load. Identification by molecular analysis of amplified fragments through the expansion D2/D3 28S rDNA confirmed the presence of only Rhabditis blumi. Based on clinical, morphologic and molecular examination, it appears to be the first report of the occurrence of R. blumi infection in Gir cattle in the State of Pará, due to the purchase of cattle from areas where parasitic otitis has been diagnosed, as from Minas Gerais, to produce crossbred animals (Gir x Holstein). This emphasizes the importance of prior clinical examination by the veterinary service in order to transfer only healthy animals to other properties or regions. This appears also to be the first report on R. blumi infection of the conjunctival sac in cattle. Treatment with ivermectin in G2 did not produce clinical improvement.(AU)
