[Ear tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed patient, in Bamako, Mali]. / Tuberculose auriculaire concomitante à une localisation pulmonaire chez un patient immunodéprimé par le VIH, à Bamako, Mali.

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.

What's in a child's ear? A case of otomyiasis by Sarcophaga argyrostoma (Diptera, Sarcophagidae).

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.

Pilot study of dogs with suppurative and non-suppurative Malassezia otitis: A case series.

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.

Chronic Otitis in Cats: Clinical management of primary, predisposing and perpetuating factors.

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.

Recurrent polyp formation with Candida tropicalis infection and otitis in a dog.

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.

Updated Guidelines for the Management of Acute Otitis Media in Children by the Italian Society of Pediatrics: diagnosis

In recent years, new progress has been made regarding the diagnosis, treatment and prevention of acute otitis media (AOM). The Italian Pediatric Society therefore decided to issue an update to the previous guidelines published in 2010. Literature searches were conducted on MEDLINE by Pubmed, including studies in children, in English or Italian, published between January 1, 2010, and December 31, 2018. The quality of the included studies was assessed using the grading of recommendations, assessment, development and evaluations (GRADE) methodology. In particular, the quality of the systematic reviews was evaluated using the AMSTAR 2 appraisal tool. The guidelines were formulated using the GRADE methodology by a multidisciplinary panel of experts. The diagnosis of AOM is based on acute clinical symptoms and otoscopic evidence; alternatively, the presence of otorrhea associated with spontaneous tympanic membrane perforation allows the AOM diagnosis. The diagnosis of AOM must be certain and the use of a pneumatic otoscope is of fundamental importance. As an alternative to the pneumatic otoscope, pediatricians can use a static otoscope and a tympanometer. To objectively establish the severity of the episode for the formulation of a correct treatment program, an AOM severity scoring system taking into account clinical signs and otoscopic findings was developed.The diagnosis of AOM is clinical and requires the introduction of specific medical training programs. The use of pneumatic otoscopes must be promoted, as they are not sufficiently commonly used in routine practice in Italy.

Health Extension Workers' diagnostic accuracy for common childhood illnesses in four regions of Ethiopia: a cross-sectional study.

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.

Muenke syndrome: Medical and surgical comorbidities and long-term management.

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.

Infections of the Ear.

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.

Otitis and meningoencephalitis associated with infectious coryza ( Avibacterium paragallinarum) in commercial broiler chickens.

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.

Agranulocitosis en niña de 6 años. ¿Qué hay detrás? / Agranulocytosis in a 6 year-old girl. What's behind it?

El síndrome de Kabuki (SK) es una rara enfermedad genética que cursa con importantes alteraciones cardiacas e inmunológicas. La mayoría de los pacientes son diagnosticados en los primeros años de vida pese a que la edad de inicio no está bien definida. Los pacientes afectos presentan infecciones de repetición debido a su inmunosupresión pudiendo llegar a un estado de agranulocitosis. Aunque su pronóstico es bastante favorable, su esperanza de vida viene condicionada por este tipo de complicaciones. Por ello, conocer sus características analíticas particulares resulta interesante desde el punto de vista del laboratorio de hematología para contribuir en su orientación diagnóstica y en el seguimiento de los mismos. Presentamos el caso de un paciente diagnosticado de SK

Kabuki syndrome (KS) is a rare genetic disease that usually involves significant cardiac and immunological disorders. Most patients are diagnosed in the first years of life, despite the fact that the age of onset is not well-defined. Affected patients have recurrent infections due to their immunosuppression, and may reach a state of agranulocytosis. Although their prognosis is quite favourable, their life expectancy is determined by these types of complications. Therefore, to understand its particular analytical characteristics is interesting from the point of view of the Haematology Laboratory to contribute to their diagnosis and follow-up. The case is presented of a patient diagnosed with KS

Evidence-Based Advances in Rabbit Medicine.

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.

Early diagnosis of PI3Kδ syndrome in a 2 years old girl with recurrent otitis and enlarged spleen.

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).

Surgical Treatment for Epstein-Barr Virus Otomastoiditis Complicated by Facial Nerve Paralysis: A Case Report of Two Young Brothers and Review of Literature.

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.
