Acute neuromuscular manifestations in a patient associated with ingesting octopus (Octopus sp.)

The authors report neuromuscular manifestations in a 45-year-old woman after consuming octopus meat (Octopus sp.). The patient presented malaise, paresthesias in perioral and extremity areas, intense muscular weakness and arterial hypotension, followed by severe itch and disseminated cutaneous rash. Gastrointestinal manifestations and fever were not observed, reducing the probability of alimentary poisoning. The presence of muscular and neurological symptoms suggests neurotoxin action, which could have been ingested by the victim from the octopus salivary glands or from an accumulation of toxins in the meat, or by an unknown mechanism. There is little known about toxins of the Octopus genus and this communication is important alert to the possibility of poisoning in humans that eat octopus and its differentiation from alimentary poisonings arising from incorrect conservation of seafood.

Intraepidermal Epidermotropic Metastatic Melanoma: a Clinical and Histopathological Mimicker of Melanoma in Situ Occurring in Multiplicity

The distinction between primary melanoma and melanoma metastatic to the skin has major prognostic implications. We report a case of a 67-year-old male with a diagnosis of a superficial spreading melanoma (stage IB) rendered 6 years earlier who presented clinically with an atypical nevus on his left thigh. Histopathological examination showed an intraepidermal melanocytic proliferation that was interpreted as melanoma in situ. Subsequently, 45 additional pigmented macules appeared in crops over a 9-month period. Clinically and dermoscopically, these lesions were extremely polymorphic. Histopathological findings were compatible with melanoma in situ, as each lesion consisted of a wholly intraepidermal proliferation of markedly atypical melanocytes arranged singly and in nests. A complete gastrointestinal study showed multiple pigmented metastatic lesions throughout the stomach and small bowel, which supported a diagnosis of metastatic melanoma with gastrointestinal and epidermotropic skin involvement. Monosomy of chromosome 9 and a BRAF V600E mutation were detected in the primary tumor sample and in macro-dissected secondary lesions. No CDKN2A or CDK4 germline mutations were found. Intraepidermal epidermotropic metastases of melanoma have been rarely described in literature. In this case, histopathology alone was insufficient to distinguish metastatic melanoma from multiple in situ melanomas. The recognition of epidermotropic metastases should be based on the correlation between clinical, dermoscopic, histopathological and molecular findings.

No Fate But What We Make: a Case of Full Recovery After Out-of-Hospital Cardiac Arrest

An 80 years old man suffered a cardiac arrest shortly after arrival to his local health department. Basic Life Support was started promptly and nine minutes later, on evaluation by an Advanced Life Support team, the victim was defibrillated with a 200J shock. When orotracheal intubation was attempted, masseter muscle contraction was noticed: on reevaluation, the victim had pulse and spontaneous breathing.Thirty minutes later, the patient had been transferred to an emergency department. As he complained of chest pain, the ECG showed a ST segment depression in leads V4 to V6 and laboratory tests showed cardiac troponine I slightly elevated. A coronary angiography was performed urgently: significant left main plus three vessel coronary artery disease was disclosed.Eighteen hours after the cardiac arrest, a quadruple coronary artery bypass grafting operation was undertaken. During surgery, a fresh thrombus was removed from the middle left anterior descendent artery. Post-operative course was uneventful and the patient was discharged seven days after the procedure. Twenty four months later, he remains asymptomatic.In this case, the immediate call for the Advanced Life Support team, prompt basic life support and the successful defibrillation, altogether, contributed for the full recovery. Furthermore, the swiftness in the detection and treatment of the acute reversible cause (myocardial ischemia in this case) was crucial for long-term prognosis.

Frequency of toxocara infection in children attended by the health public service of Maringá, south Brazil

The lack of specific laboratorial diagnosis methods and precise symptoms makes the toxocariasis a neglected disease in Public Health Services. This study aims to determine the frequency of Toxocara spp. infection in children attended by the Health Public Service of Hospital Municipal de Maringá, South Brazil. To evaluate the association of epidemiological and clinical data, an observational and cross-section study was carried out. From 14,690 attended children/year aged from seven month to 12 years old, 450 serum samples were randomly collected from September/2004 to September/2005. A questionnaire was used to evaluate epidemiological, clinical and hematological data. An ELISA using Toxocara canis larval excretory-secretory products as antigen detected 130 (28.8%) positive sera, mainly between children from seven month to five years old (p = 0.0016). Significant correlation was observed between positive serology for Toxocara, and frequent playing in sandbox at school or daycare center (p = 0.011) and the presence of a cat at home (p = 0.056). From the families, 50% were dog owners which exposed soil backyards. Eosinophilia (p = 0.776), and signs and symptoms analyzed (fever p = 0.992, pneumonia p = 0.289, cold-like symptoms p = 0.277, cough p = 0.783, gastrointestinal problems p = 0.877, migraine p = 0.979, abdominal pain p = 0.965, joint pain p = 0.686 and skin rash p = 0.105) could not be related to the presence of anti-Toxocara antibodies. Therefore, two asthmatics children showed titles of 1:10,240 and accentuated eosinophilia (p = 0.0001). The authors emphasize the needs of prevention activities.

Cytomegalovirus in colorectal cancer and idiopathic ulcerative colitis

Cytomegalovirus (CMV) is a genus in the family Herpesviridae that has been associated with gastrointestinal syndromes. In this work we looked for a possible association of CMV infection with colorectal cancer and ulcerative colitis (UC). Blood and enteric tissue samples of 14 patients with colorectal cancer and of 21 with UC were subjected to a nested-PCR that amplifies part of the gB gene of CMV and also to immunohistochemistry using a specific monoclonal antibody to IE 76kDa protein of CMV. CMV was detected by nested-PCR in the blood and/or the enteric tissue of nine (64.3%) colorectal cancer and 16 (76.2%) ulcerative colitis patients. In the immunohistochemistry it was observed that 12 (12/21, 57.1%) positive enteric tissue samples of patients with UC and none from patients with colorectal cancer (0/14) were positive to CMV. The positivity of CMV infections in the UC patient group (12/21, 57.1%) showed by both techniques, was significantly higher (p = 0.015) than that observed for colorectal cancer patients (2/14, 14.3%). These results suggest an association of ulcerative colitis with CMV infection of the enteric tissue.

Case Report: Purple Urine Bag Syndrome

Purple urine bag syndrome (PUBS) was first reported in 1978. PUBS is rare, occurs predominantly in constipated women, chronically catheterized and associated with some bacterial urinary infections that produce sulphatase/phosphatase. The etiology is due to indigo (blue) and indirubin (red) or to their mixture that becomes purple. A chain reaction begins in the gastrointestinal tract with tryptophan as described in the article.

A Vertente Cirúrgica de uma Unidade de Cuidados Intensivos Neonatais – 25 Anos de Experiência

Introdução e objectivos: O Hospital de Dona Estefânia é um hospital pediátrico com Área de Cirurgia Pediátrica e uma Maternidade da Apoio Perinatal Diferenciado. O objectivo deste estudo prospectivo histórico é analisar a população de recém-nascidos (RN) admitidos na Unidade de Cuidados Intensivos Neonatais (UCIN) submetidos a intervenção cirúrgicanum período de 25 anos. Métodos e doentes: Os dados foram obtidos de estudos de casuística e do ficheiro electrónico da UCIN. Foi realizada pesquisa individual pelo código de intervenção cirúrgica e pelo código de cada uma das condições cirúrgicas. Todos os RN submetidos a intervenção cirúrgica foram englobados. Cada doente foi contabilizado apenas uma vez mas as anomalias cirúrgicas major foram contabilizadas uma a uma. As taxas de letalidade são brutas, englobando-se no denominador todos os RN com a mesma anomalia, operados. Resultados: Neste período foram admitidos na UCIN 5937 RN dos quais 1140 (19.2%) foram operados. A mediana do tempo de internamento foi 30 dias. O número de RN submetidos a intervenção cirúrgica subiu de 2% dos admitidos em 1983 para 29.4% em 2007. Vinte e seis por cento do total de operados nasceram na maternidade do hospital. A patologia gastrointestinal foi a mais frequente tanto no grupo da patologia congénita como no grupo da adquirida; a patologia torácica/pulmonar ocupou o 2º lugar no grupo da patologia congénita, constituindo a hérnia diafragmática congénita a situação mais frequente. Na alta, 35% dos doentes (n=404) foram enviados para o domicílio, 51% (n=581) foram transferidos para outro serviço e 14% faleceram (n=155). A mortalidade diminuiu de 22% nos primeiros 10 anos para menos de 10% nos últimos 10 anos e 5% nos últimos 5. A mortalidade da atrésia do esófago baixou de 22% nos primeiros 15 anos para 3,8% nos últimos 5 e a da hérnia diafragmática de Bochdalek de 34% nos primeiros 15 anos para 28% nos últimos 10. Conclusões: A concentração de patologia cirúrgica neonatal num centro de referência melhora a experiência das equipas multidisciplinares podendo contribuir para um melhor prognóstico de doentes com patologia grave.

Temporomandibular Joint Ankylosis in an Infant: A Rare Cause of Difficult Airway

1.Pre-assessment data of the patient A 2-year-old boy, weighing 15 kg was admitted with a history of limited mouth opening(inter-incisor distance of 6 mm), hypoplastic and retrognathic mandible (bird face deformity) and facial asymmetry from left temporomandibular joint ankylosis (TMJA). He was born at term, after an uneventful pregnancy, and there was no report of trauma during caesarean section. No other possible aetiologies were identified. He was scheduled for mandibular osteotomy. Preoperative ENT examination revealed adenotonsillar hypertrophy. 2. Anaesthetic Plan A fiberoptic nasal intubation was performed under deep inhalation anaesthesia with sevoflurane, with the patient breathing spontaneously. Midazolam (0.05 mg.kg-1) and alfentanil (0.03 mg.kg-1) were given and anaesthesia was maintained with O2/air and sevoflurane. No neuromuscular blocking agent was administered since the surgical team needed facial nerve monitoring. 3. Description of incident During surgery an accidental extubation occurred and an attempt was made to reintubate the trachea by direct laryngoscopy. Although the osteotomy was nearly completed, the vocal cords could not be visualized (Cormack-Lehane grade IV laryngoscopic view). 4. Solving the problem Re-intubation was finally accomplished with the flexible fiberscope and the procedure was concluded without any more incidents. Extubation was performed 24 hours postoperatively with the patient fully awake. After surgery mouth opening improved to inter-incisor gap of 15 mm. 5. Lessons learned and take home message Two airways issues present in this case can lead to difficultventilation and intubation: TMJA and adenotonsillar hypertrophy. These difficulties were anticipated and managed accordingly. The accidental extubation brought to our attention the fact that, even after surgical correction, this airway remains challenging. Even with intensive jaw stretchingexercises there is a high incidence of re-ankylosis, especially in younger patients. One should bear that in mind when anaesthetizing patients with TMJA.

Primary Disorders of Neurotransmitter Metabolism: Experience of a Tertiary Center

Neurotransmitter diseases are a group of inherited disorders attributable to a disturbance of neurotransmitter metabolism. Biogenic amines are neurotransmitters with multiple roles including psychomotor function, hormone secretion, cardiovascular, respiratory and gastrointestinal control, sleep mechanisms, body temperature and pain. Given the multiple functions of monoamines, disorders of their metabolism comprise a wide spectrum of manifestations, with motor dysfunction being the most prominent clinical feature. Methods: Case review of 12 patients from 4 families, with primary disorders of biogenic amine metabolism. Results: Aromatic L-amino acid decarboxylase deficiency (4 patients from 2 families), and GTP-cyclohydrolase (8 patients from 2 families) were the two diseases identified. Age at first symptoms varied between 2 months and 6 years. Developmental delay was present in all cases except 2 patients with GTP cyclohydrolase deficiency. The combination of axial hypotonia and limb dystonia was also frequent. Children with aromatic L-amino acid decarboxylase deficiency exhibited temperature instability, oculogyric crisis and disturbances of sleep. The index case of one family with GTP cyclohydrolase deficiency presented with Parkinsonism (bradykinesia, rigidity and hypomimia). Analysis of neurotransmitters and their metabolites in CSF was crucial for the identification of index cases. Response to therapy was variable but in general unsatisfactory except in a family with GTP cyclohydrolase deficiency. Conclusions: These disorders should be considered in the differential diagnosis of paediatric neurodegenerative diseases, in order to allow an adequate therapeutic trial that can favor prognosis.

Síndrome da Cauda Equina em Anestesia Obstétrica: Caso, Factos e Causas

Introdução: A incidência de síndrome da cauda equina foi quantificada em <0,23: 10 000 na anestesia obstétrica. Apesar da raridade, as suas consequências podem ser geradoras de limitações importantes na qualidade de vida das pacientes, daí a pertinência da análise deste caso clínico. Grávida de 34 anos com antecedentes de VIH2, VHC e linfoma não Hodgkin em remissão desde há 5 anos submetida a bloqueio subaracnoideu e colocação de cateter epidural para cesariana. A abordagem do espaço epidural foi difícil. Administrou-se 7,5mg de levobupivacaína e 0,0025mg sufentanil no espaço subaracnoideu e a paciente queixou-se de dor tipo choques eléctricos e parestesias nos membros inferiores durante segundos. Após 1:30h, na UCPA, a paciente iniciou o mesmo tipo de dor na região sacrococcígea e coxas após administração morfina e metilprednisolona no espaço epidural, a qual foi debelada com paracetamol, cetorolac, dipirona e petidina. A remoção do cateter epidural foi difícil. No pós-operatório a paciente sentiu tremor ao nível da coxa esquerda e parestesias na coxa direita. Pela raridade do síndrome da cauda equina, a análise do ocorrido é pertinente contrapondo com descrições prévias, em virtude duma intervenção anestésica mais segura.

Norovírus Associated Encephalopathy

clinical presentation is self limited. It is classified into five groups (genogroups I through V). There are numerous reports of neurologic complications, namely afebrile seizures, but only two reports of associated encephalopathy. Case Report: A 12 month old girl with previous history of a pneumonia treated with amoxicillin-clavulanic acid and clarythromycin, presented in our emergency department with strabismus, ataxia for 3 days, later associated with vomiting and diarrhea. On admission she had ataxia and an episode of strabismus, but her later neurologic exam was normal. Laboratory data revealed: 10,9 g/dL hemoglobin, 11.200/μL leukocytes, 29,1% neutrophils and 65,2% lymphocytes, 488.000/μL platelets and negative CRP. The brain MRI showed middle ear, maxillary sinus and ethmoidal opacification, with no other abnormalities. During the first day of admission she had a tonic (?) seizure for 20 minutes. CSF analysis showed 5,6 cells/μL, 100% lymphocytes, 80 mg/dL glucose and 154,1 mg/dL protein. The EEG revealed short duration paroxystic activity located to the vertex. She was treated with acyclovir, ciprofloxacin, cefthriaxone and phenytoin. Her symptoms resolved by the third day of admission. Blood samples were tested for numerous pathogens, including serology for Borrelia, which was positive for IgG but negative for IgM. Fecal sample analysis revealed positive PCR for norovirus, although it was negative in CSF samples. IL-6 was measured in the CSF and was negative (5,8 pg/mL). She had a history of recurrent otitis media and pernieal candidiasis, which led to a detailed immune function study, which showed Immunology tests revealed diminished IgA (< 0,244 g/L) and absent antibody response to vaccinations. Since she was only 13 months old when she was tested, only follow up will determine the relevance of these values. Follow up at two years of age showed no delays and a normal development. Conclusion: Norovirus encephalitis is a rare entity, although gastrointestinal infection with this agent is relatively common. Here we present a case of a probable norovirus associated encephalopathy, although PCR for norovirus was negative in CSF samples and there was no CSF cytokine increase. It was not associated with adverse neurologic outcome and so far her development is normal, unlike the evolution described in previous case reports.

Enterococcus gallinarum meningitis in an immunocompetent host: a case report

We describe a rare case of a 53-year-old man with a long history of alcohol abuse, with Enterococcus gallinarum meningitis, an organism that rarely causes human infection and is primarily found in the gastrointestinal tract of poultry. The patient improved with high-dose ampicillin and gentamicin therapy. To our knowledge, this is the first Brazilian reported case of E. gallinarum meningitis and probably the first case described in an immunocompetent host.

Staphylococcus warneri meningitis in a patient with Strongyloides stercoralis hyperinfection and lymphoma: first report of a case

A case of meningitis due to Staphylococcus warneri in a patient with a hyperinfection with Strongyloides stercoralis possibly associated with rituximab treatment for mantel cell lymphoma is reported for the first time in the literature. The patient was a 59-year-old woman, with a 3-year history of an apparently well controlled lymphoma after treatment with chemotherapy-immunotherapy and then immunotherapy alone, and diagnosis of strongyloidiasis. Meningitis was diagnosed by cerebrospinal fluid culture and tested with an automated plate system. The patient was successfully treated with vancomycin; although fever and productive cough persisted. Severe gastrointestinal symptoms and pneumonia developed three weeks later. Hyperinfection syndrome by S. stercoralis was diagnosed, with abundant larvae in feces and expectoration.

Metástase Uterina de Carcinoma da Mama. A Propósito de um Caso Clínico

Estão raramente descritos na literatura casos de metástases uterinas de cancros extra genitais, sendo o aparelho genital feminino normalmente invadido por contiguidade. Mais frequentes são contudo, as metástases ováricas de neoplasias extragenitais sobretudo do aparelho gastrointestinal e mama. Descrevemos o caso clínico de uma doente de 71 anos que recorreu ao serviço de urgência por metrorragias pós menopausa (sem THS), tendo sido diagnosticado pólipo do endocolo e efectuada polipectomia. No exame anatomopatológico foi identificada, no eixo do pólipo, uma infiltração neoplásica compatível com metástase de carcinoma lobular da mama. A doente encontra-se desde há um ano a efectuar Quimioterapia com boa resposta.
