Adenocarcinoma de apêndice: Relato de dois casos e revisão da literatura

Background: The adenocarcinoma of the appendix is a rare disease, generally identified as an acute appendicitis in the clinical presentation. Preoperative diagnosis is extremely difficult and uncommon. Objective: To present two cases of adenocarcinoma of the appendix, unique for presenting in early ages, and a complete literature review on this topic. Cases report: First case: a 24-year-old man submitted to appendectomy for acute inflammatory abdomen. Sent to hospital due to a histopathological diagnosis of mucinous adenocarcinoma of the appendix. Right hemicolectomy, epiploectomy, ganglion and partial abdominal wall resection were performed. The patient is now in chemotherapy. Second case: a 32-year-old man presented, during appendectomy, with vegetant lesion on the apex of the appendix. The histopathological study revealed the presence of adenocarcinoma of the appendix. Right hemicolectomy with ganglion resection was performed. The patient does not present signs of recurring disease. Conclusion: The macroscopic and clinical similarity between adenocarcinoma of the appendix and acute appendicitis makes it important to check out histopathological study results. The cases above reinforce this requirement, as the authors have found adenocarcinoma of the appendix in young patients.

Polineuropatia associada a hipotireoidismo em cães: Relato de seis casos

Six Doberman Pinscher, between six and eight years of age, were presented to the Veterinary Hospital from Faculty of Veterinary Science of The University of Buenos Aires. Neurological examination revealed tetraparesis with inability to walk, decreased muscle tonus and myotatic reflexes in all dogs. Serum cholesterol levels, creatine kinase and alkaline phosphatase activities were mildly to markedly elevated, and tibial motor nerve conduction velocities were slow in all dogs. Basal measurements of free T4 and TSH were determined by radioimmunoassay. Although fT4 values were within normal range, in all dogs TSH values were elevated. Based on this results, hypothyroidism was diagnosed and a supplementation therapy was established with oral levothyroxine (T4). Two weeks after treatment has been started, all patients had an improvement in clinical signs, and within a month gait became normal, as well as muscular tonus and spinal reflexes.

Edema agudo de pulmão de pressão negativa como complicação grave de síndrome de apneia obstrutiva do sono em crianças. Relatos de casos

Introduction: Obstructive sleep apnea syndrome is related to cardiopulmonary complications in children. It is important to know its patophysiology and possible complications to help reduce risks in this group. Aims: To report three cases of severe cardiorespiratory complications of obstructive sleep apnea managed in the intensive care unit (ICU). Case report: Two children with no previous diagnosis of obstructive sleep apnea syndrome suffered acute congestive heart failure and acute lung oedema with need of ICU and improved after adenotonsillectomy. In a third case, the patient had acute lung oedema as a complication after adenotonsillectomy. Conclusions: Paediatricians and otolaryngologists must be aware of the clinical manifestations of severe sleep apnea. Early referring to treatment and special attention at pre and post surgical periods are essentials to avoid serious complications.

Dermatopatias em cães: Revisão de 257 casos

The purpose of this study was to collect data on skin diseases in dogs evaluated at the Veterinary Hospital of the Northern Parana State University (UENP), in Bandeirantes, Parana, Brazil. Dermatological conditions amounted to 31.38% of all consultations in dogs, and the most common skin conditions observed were, from the most to the least common: bacterial, parasitic, fungal, immune, and keratinization disorders; general skin diseases and psychogenic conditions. The highest scoring diseases, in number of occurrences were, in descending order: Superficial folliculitis, demodicidosis, dermatophytosis, bacterial otitis, deep folliculitis, dry dekeratinization, allergic dermatitis caused by flea bites, fungal ear infections, scabies, impetigo, malassezia dermatitis, parasitical otitis, pad dermatitis, and atopic dermatitis.

Carcinoma de células transicionales en perros: Un informe de dos casos, madre e hija

The transitional cell carcinoma is usually located in the trigone region of the bladder, and shows nonspecific clinical signs of the lower urinary tract such as hematuria, strangury, pollakiuria and urinary incontinence. The urethral and ureteral obstructions occur in some cases. Etiological factors such as endogenous and iatrogenic have been listed as the cause of disease. The objective of this report is to describe the process and treatment of two cases of transitional cell carcinoma presented simultaneously in two dogs, mother and daughter, that showed hematuria and post-renal azotemia, both with tumor in the trigone of bladder. After partial cystectomy ureteroneocistostomia, the diagnosis of transitional cell carcinoma was confirmed by histopathological analysis of bladder tissue. Patients received firocoxib as adjuvant to surgery. It is concluded that the surgical procedure associated with the use of specific anti-inflammatory COX-2 provided a better quality of life in both patients.

Enfisema lobar congênito: série de casos de 30 anos em dois hospitais universitários

Objetivo: Revisar os casos de enfisema lobar congênito (ELC) operados nos últimos 30 anos em dois hospitais universitários. Métodos: Foram revistos os prontuários médicos das crianças com ELC operadas no Hospital das Clínicas da Faculdade de Medicina de Botucatu e no Hospital da Universidade de Mogi das Cruzes entre 1979 e 2009. Dados sobre sintomas, exame físico, achados radiológicos, diagnóstico, tratamento cirúrgico e seguimento pós-operatório mediato e tardio foram analisados. Resultados: Durante o período estudado, 20 crianças com ELC foram submetidas a tratamento cirúrgico. A média de idade dos pacientes no momento da cirurgia foi 6,9 meses (variação, 9 dias a 4 anos). Todos os casos apresentaram sintomas ao nascimento ou nos primeiros meses de vida. Em todos os casos, a radiografia simples de tórax foi importante na definição do diagnóstico. Em casos de dificuldade respiratória moderada, a TC de tórax auxiliou no diagnóstico. Um paciente com desconforto respiratório grave foi diagnosticado erroneamente com pneumotórax hipertensivo e submetido a drenagem torácica. A broncoscopia só foi realizada nos pacientes com dificuldade respiratória moderada e não foram encontrados sinais de anomalias traqueobrônquicas. A abordagem cirúrgica foi realizada através de toracotomia lateral poupadora de músculo. O lobo superior esquerdo e o lobo médio foram os mais afetados, seguidos pelo lobo superior direito. A lobectomia foi realizada em 18 casos, enquanto a bilobectomia foi realizada em 2 casos (com ressecção de cisto broncogênico em 1 desses). Complicações pós-operatórias não foram observadas. O acompanhamento pós-operatório foi de pelo menos 24 meses (média, 60 meses) e não foram observadas complicações tardias nesta série. Conclusões: O ELC é uma doença pouco comum, ainda negligenciada, de etiologia incerta, mas de fácil diagnóstico radiológico e tratamento cirúrgico eficaz.

Encalhes de tubarões anequins e de raias-pretas no litoral do estado de São Paulo, sudeste do Brasil: Relato de casos

Stranding of oceanic-pelagic elasmo branchs in the southeastern Brazil are reported. Data comes from animals observed in the coast of São Paulo state, between 1999 and 2012. Nine individuals of two species were recorded: Pteroplatytrygon violacea (n = 5; mostly during the winter) and Isurus oxyrinchus (n = 4; two in the winter and two in the summer). For P. violacea the strandings restricted to the austral winter suggest that the species follows the intrusion of high temperatures water masses recorded in southeastern Brazil during this season, bringing some individuals to shallow waters. For I. oxyrinchus is possible that individuals escaped from hooks of the commercial pelagic long line fishery and suffered injuries in the esophagus and in the gastric wall, stranding due to difficulties in locomotion and feeding. As these stranded sharks were not necropsied and only two animals were observed during the austral summer, we cannot exclude other causes of beaching such diseases or the intrusion of cold water masses in the continental shelf during this season.
