ABSTRACT
Posterior perilunar dislocation of the carpus or retrolunar dislocation is a lesion where the capitatum is displaced behind the lunatum, and constitutes the most frequent perilunar fracture dislocation. It should be considered asa therapeutic emergency and the treatment should be absolutely surgical. The authors report a case of pure posterior perilunar dislocation of the carpus following an accident on the public highway. The patient underwent an urgent reduction followed by fixation with two scapholunar, and triquetrolunar pins by the posterior and medial approach, and immobilization for six weeks. After a 12months follow-up, the functional outcomes were satisfactory.

ABSTRACT
Introduction: In children, the pudendal block has recently experienced a significant boom in ensuring quality perioperative analgesia for perineal surgeries. The purpose of this work is to describe the process and the effectiveness of the pudendal block performed under neurostimulation. Patients and Method: This is a prospective study carried out in the pediatric surgery department of the UHC-MCL, from November 17to the 22nd of November 2019 and it included all the children aging from 0 to 15 years old who would not only have benefited from a program within the framework of the funfair mission for hypospadias surgery but also be eligible for the pudendal block itself. The pudendal block was found to be effective in the absence of pain using the scale of 6 faces modified every 2 hours until the 24th hour. The data were collected from a form designed for this purpose. They were analyzed using Stata Version 14 software. Results: A total of 42 children had benefited from a surgical consultation but 18 were eligible (42.85%) for the present study. The latter had an average age of 6-10 ± 2.23 years with extremes from 10 months of life to 14 years. Hypospadias (anterior and balanic) was the most widely used surgical indication (55.55%). The children were classified ASA1 (92%) and ASA2 (8%). The pain assessment score was between 0 - 3after 24 hours in 100% of children subsequently explaining the efficacy of the pudendal block. The average stay during hospitalization was 1.12 +/- 0.36 days; the perioperative morbidity and mortality was null. Conclusion: The Pudendal Block seems to provide pretty good analgesia and a certain post-operative comfort to children who had surgery done. Taking into account the quality of the surgeries done on patients, , the cost, the efficiency of the procedure and the post-operative comfort hence the realization of the pudendal block constitutes an alternative for fairground care.

ABSTRACT
Introduction: in the cell, physiological processes depend on time and circadian rhythms. The synchronization of time, in childhood and old age, may be related to hyperbolic lines of force in Earth's magnetic field. Methods: in relation to childhood and old age, scientific papers on physiological hyperbolic curves, Earth's magnetic field and time were reviewed. Results: There are hyperbolic curves and circadian rhythms in physiology. In childhood the geological (clock) time is very short, while the psychological time is long, with rapid physiological processes. In old age the geological time (clock) is very long, while the psychological time is short, with slow physiological processes. The lines of force in a magnet and in the Earth's magnetic field are hyperbolic images that deform the surrounding space. There is the possibility of modifying the hyperbolic dimensions of a physiological process, when we act in its time and space of development. In this way it could serve in the treatment of diseases. Conclusions: regarding geological time (clock), in childhood the psychological and physiological times are dilated, while in old age they are contracted. At birth, a "long life biorhythm" appears in cellular physiology and this ranges from birth to death. This biorhythm in cellular physiology is hyperbolic because it synchronizes with the hyperbolic lines of force in Earth's magnetic field. If external stimuli are applied to modify the hyperbolic physiological curves, they tend to synchronize again to become hyperbolas as before.

ABSTRACT
Background: SARS-COV-2 has brought untold hardship, economic meltdown, mystery and deaths to the world and has been declared a global pandemic by the WHO. The aim of this study is to review evidence that either support or refute the hypothesis that some level of relationships exists between vitamin D serum level and the risk of COVID-19 disease as well as its clinical outcome. Materials and Methods: A Pubmed/Medline, Google scholar, JSTOR, and AJOL search was performed in May 2020 for studies that links COVID-19 to serum levels of vitamin D. Search terms used include a combination of vitamin D, ascorbic acid, 25-hydroxycholecalciferol, corona virus, COVID-19, and SARS-COV-2. Results and Discussion: A total of 79 articles were identified (mostly from Pubmed / Medline and Google scholar) after removal of duplicates, out of which 7(5.9%) articles met the inclusion criteria. 85% of the studies reported that a link exist between Vitamin D levels and risk of COVID-19 infection and also, that being positive for COVID-19 was associated with deficiency or lower levels of vitamin D. Critical cases of COVID-19 and its associated mortality was linked to deficiency or lower serum levels of vitamin D in some studies. Age, sex and ethnicity are important factors that determine the outcome of these relationships. Conclusion: This study adds to body of evidence that the risk of COVID-19 and its clinical outcome is associated with the vitamin D levels of the subjects. There is a need to include serum Vitamin D testing parameter among COVID-19 patients in their treatment centers across the globe and in Nigeria in particular.

ABSTRACT
Hydatid disease is a major health problem worldwide. The acute pancreatitis is a rare complication of this disease. We reported the case of 53 years-old man, who presented with upper abdominal pain, jaundice, a high level of lipase and Abdominal CT scan showed an hydatid cysts lesion and an inflammatory pancreas. Acute pancreatitis was treated in first time and after that a surgery was performed treating the hydatid liver cyst. The patient made an uneventful recovery after surgery.

ABSTRACT
Celiac disease (CD) is associated with an increased risk for malignancy, especially digestive adenocarcinoma and lymphoproliferative neoplasms. We briefly present two cases with a short review of the current literature.

ABSTRACT
Non-Hodgkin’s lymphoma is a rare primary neoplasm of the epidural spine of the elderly. Although lymphomatous involvement of vertebral bodies will be recognized as marked high signal on STIR images, the radiological features are still unspecific, which make it difficult for identification. We report a case of a 86-year-old man complaining of serious lower lumbar pain and lower limbs muscle weakness. The PET-CT scan showed invasion of the fifth lumbar vertebra without migration. As the posterior vertebral body wall collapsed, never roots were compressed by the instability. The Spinal Instability Neoplastic Score (SINS) was 13. Vertebroplasty was performed to consolidate the vertebral and followed by decompression and interal fixation, afterward, the pain and lower limb weakness was relieved. The histopathological examination revealed a diffuse lymphoma. RminiCHOP chemotherapy was applied following the surgery in the department of hematology. Until the 12 months follow-up, the clinical result was satisfied.
