Le Zona est une infection virale aiguë, sporadique et douloureuse chez les personnes âgées, causée par la réactivation du virus de la varicelle-zona latent. C’est une affection dermatologique fréquente qui affecte jusqu'à 20 % de la population, le plus souvent impliquant les dermatomes thoraciques et faciaux avec des lésions sacrées. L'herpès zoster affectant le creux poplité est une pathologie rare. La nature ambiguë de cette condition crée un dilemme diagnostique. Nous rapportons l’observation d’une patiente âgée ayant présenté une localisation exceptionnelle du zona : le creux poplité. C’est le premier cas décrit du zona du creux poplité confirmé par la PCR (Polymerase Chain Reaction) avec des caractéristiques distinctives secondaires chez une femme âgée.

Vários estudos descreveram o acúmulo de uma deleção do DNA mitocondrial (DNAmt), denominada de deleção comum, em tecidos pós-mitóticos durante o processo de envelhecimento. Esses achados levaram A hipótese de que radicais livres, gerados dentro da mitocandria, poderiam lesar o DNAmt durante a vida normal. Acredita-se que um defeito no funciomento da cadeia respirat6ra, decorrente da lesão do DNAmt, levaria a um aumento na produção de radicais livres, que por sua vez, lesariam o DNAmt, criando um ciclo vicioso é um fator importante no acúmulo de deleções do DNAmt, pacientes com deficiência da função oxidativa (independente do defeito primário) deveriam apresentar um acúmulo acelerado de deleções do DNAmt. Nós testamos esta hipótese através de três analises: (a) comparação dos níveis de deleção comum em controles normais e pacientes com doenças mitocondriais geneticamente caracterizadas e associadas com uma mutação do DNAmt; (b) análise da cosegregação da deleção comum (associada com o envelhecimento) com uma mutação de ponto patogênica do DNAmt; e (c) detecção de deleções múltiplas do DNAmt através de PCR (polymerase chain reaction) longo em controles e pacientes com doenças mitocondriais. Observamos uma correlação positiva entre a idade e MN/6s de deleção comum em controles (r = 0,80) e pacientes (r = 0,69). As inclinações das curvas eram semelhantes, sugerindo que a taxa de acúmulo da deleção comum associada com a idade era a mesma em ambos os grupos. Não conseguimos observar a co-segregação das moléculas de DNAmt contendo a mutação de ponto com a deleção comum e nem aumento no número de deleções em pacientes. Nossos resultados não suportam a hipótese de que o ciclo vicioso (lesão do DNAmt afeta a função da cadeia respiratória, levando a uma maior produção de radicais livres que, por sua vez, provocaria mais lesão do DNAmt) é um fator importante no acúmulo de deleções do DNAmt no processo de envelhecimento.

AbstractA parotid gland mass with presenting features of malignancy is a diagnostic and therapeutic challenge. The histological nature of the lesion must be clearly determined before proceeding with facial nerve sacrificing surgery. Although rare, tuberculosis of the parotid gland must be included in the differential diagnosis of a parotid gland mass especially when the social characteristics of the patient suggests a mycobacterial infection. Primary tuberculosis of the parotid gland is generally encountered among populations with a high incidence of pulmonary disease. The difficulty in the differential diagnosis of a parotid gland malignancy may be helped by a high degree of clinical suspicion, since laboratory tests generally do not identify the specific causative organism. This article reports the first case of parotid gland tuberculosis with clinical and radiodiagnostical features simulating malignancy in which the diagnosis was confirmed by the polymerase chain reaction (PCR).

Abstract Efforts to recognize SARS–CoV-2 infection have focused on respiratory symptoms such as cough and shortness of breath. Although it is also well known that SARS–CoV-2 infection can cause gastrointestinal symptoms such as abdominal pain, nausea, vomiting and diarrhoea, there are emerging reports of SARS–CoV-2 infection causing surgical pathology. We present the first case report of SARS–CoV-2 infection directly causing acute appendicitis, first suspected due to highly atypical histological features and later confirmed as polymerase chain reaction positive appendicular tissue sample.

AbstractObjectivesCoronavirus disease (COVID-19) rapidly spread worldwide in a few months and was declared as a worldwide pandemic by WHO in March 2020. Transient benign hyperphosphatasemia (THI) is a benign condition associated with marked elevation of alkaline phosphatase (ALP) without any other kidney, bone, and liver pathologies.Case presentationHerein, we report a previously healthy 16-month-old female patient who developed a secondary transient benign hyperphosphatasemia associated with SARS-CoV-2. Patient whole family’s SARS-CoV-2 real-time reverse transcription-polymerase chain reaction (RT-PCR) results were positive. Since THI is a diagnosis of exclusion, other reasons that may cause ALP elevation should be ruled out. ALP activity decreased and turned to normal ranges within the following month. THI has been reported to be in association with various conditions. Its relationship with many viruses has been reported previously.ConclusionsIf ALP elevation is detected in patients with COVID 19 due to the increasing number of infections, THI should be considered if there is no other accompanying pathology.

Skeletal tuberculosis is a well-known disease entity. We report the first case involving hyoid bone and the use of polymerase chain reaction-based test in detection and management. A 62-year-old male presented with neck swelling of a 20-day duration along with change of voice and dysphagia. Examination revealed a cystic, osteolytic lesion of the hyoid bone which histopathologically demonstrated features of granulomatous infection. A polymerase chain reaction test confirmed the diagnosis of tuberculosis.

Ikan tongkol lisong dan krai merupakan salah satu jenis tuna yang berperan nyata untuk usaha perikanan tangkap di Indonesia. Pengelolaan sumberdaya ikan tersebut harus selalu dapat dilakukan untuk menjaga tingkat pemanfaatannya supaya tidak lebih tangkap. Kajian keragaman genetik merupakan salah satu teknik dalam pengelolaan pemanfaatan sumberdaya perikanan dengan cara mengetahui tingkat keragaman genetik pada suatu struktur populasi. Kajian keragaman genetik ini diharapkan dapat menjadi basis kajian stok dan opsi dalam pengelolaan sumberdaya perikanan tongkol agar pemanfaatannya dapat dilakukan secara berkelanjutan. Awal mula analisis keragaman genetik dilakukan dengan memperbanyak DNA secara in vitro menggunakan teknik PCR (Polymerase Chain Reaction). Keberhasilan proses PCR dipengaruhi oleh beberapa faktor seperti suhu dan waktu penempelan oligonukleotida primer. Berdasarkan hal tersebut, penelitian ini bertujuan untuk mengetahui suhu dan waktu optimal pada primer Aro2-38. Sampel penelitian diperoleh dari hasil tangkapan pukat cincin yang didaratkan di PPN Palabuhanratu, Jawa Barat. Optimasi PCR menggunakan 12 suhu dan 2 waktu penempelan yang berbeda yaitu : 520C; 52,80C; 540C; 55,50C; 57,20C; 59,10C; 60,90C; 62,80C; 64,50C; 65,90C; 67,20C dan 680C, dan suhu penempelan 30 dan 15 detik. Hasil analisis menunjukkan bahwa produk PCR optimum (menghasilkan pita alel DNA) pada ikan tongkol krai berhasil waktu penempelan 30 detik dengan rentang suhu 52-540C. Sedangkan pada sampel ikan tongkol lisong, produk PCR yang optimum muncul pada waktu penempelan 15 dan 30 detik, dengan rentang suhu 52-60,90C.Frigate and bullet tuna constitute one of tuna species that plays a significant role in Indonesian fishing business. Management of fisheries resources must always be done to maintain the level of utilization so that it is not excessive. Genetic study is one of techniques in managing fisheries resource utilization by knowing the level of genetic diversity in a population structure. This genetic diversity study is expected to be the basis and option in the management of tuna fishing resources so that their utilization can be carried out sustainably. Genetic diversity analysis is start by multiplying fish DNA using PCR (Polymerase Chain Reaction) technique. The success of the PCR process is influenced by several factors such as temperature and time of primary oligonucleotide attachment. Based on this, this study aims to determine the optimal temperature and time in primers Aro2-38. The research sample was obtained from the catch of purse seine landed in PPN Palabuhanratu, West Java. PCR optimization uses 12 temperatures and 2 different annealing times: 520C; 52.80C; 54ÚC; 55,50C; 57.20C; 59.10C; 60.90C; 62.80C; 64,50C; 65,90C; 67.20C and 680C, and the annealing times are 30 and 15 seconds. The results of the analysis showed that the optimum PCR product (producing DNA allele bands) on the cretaceous tuna was successfully pasted for 30 seconds with a temperature range of 52-540C. Whereas in the sample of tuna lisong, the optimum PCR product appeared at the time of attachment of 15 and 30 seconds, with a temperature range of 52-60.90C.
