COVID-19: Public health issues and ethical dilemmas.

There are various ethical dilemmas faced by the healthcare sectors, especially at times of pandemics and health emergencies, which is more prominently visible in the case of public healthcare sectors. Keeping this into consideration, the concerned study had emphasized exploring the ethical dilemmas that are faced by the public health care sectors across the globe, in fighting the COVID-19 pandemic situations in the current period. The secondary and qualitative information collected for the concerned study has been analyzed and interpreted using the thematic analytical framework and following the inductive approach. Substantial evidence has revealed that the public health care system globally has been facing a scarcity of resources and allocation of responsibilities to the care provider. There has been disparity noted in the implementation of public health care ethics. The importance of ethics in the public healthcare system cannot be denied however, the issues noted during this pandemic situation have been associated with lack of accountability, issues in resource allocation, and loss of trustworthiness in the healthcare provisions. Hence, there is a need for changes to be made in the public policies and health policies so that the public health institutions are more prepared to deal with emergencies such as the one created by the COVID-19 pandemic.

[Cryoglobulinemia in a Tunisian internal medicine department]. / Cryoglobulinémie : expérience dans un service de médecine interne tunisien.

AIM: Cryoglobulinemia is characterized by multiple organ involvement, mainly including the skin, liver, kidneys, and peripheral nerves. Our aim was to investigate the demographic, clinical, and serologic features, as well as survival in a group of 16 Tunisian patients with cryoglobulinemia. RESULTS: The study included 12 women and 4 men, and their mean age was 41 years. In all but two, the cryoglobulinemia was associated with another disease. These included lupus for 9, Sjögren syndrome for 2, and polyarteritis nodosa for one. They also included infectious diseases: 3 patients with hepatitis B virus infection, one with hepatitis C virus infection, one with parvovirus B19, and another with lymph node tuberculosis. Only one case of lymphoproliferative disease was noted. General symptoms were present in 81% of the patients, cutaneous vasculitis in 43%, peripheral vascular-Raynaud phenomenon in 37%, joint polyarthralgia or arthritis in 62%, renal involvement in 68%, neuropathy in 25%, lung involvement in 56%, gastrointestinal involvement in 37%, and finally cardiac involvement in 31%. In some cases it was difficult to determine if the clinical signs were attributable to cryoglobulinemia or the underlying pathology. The course was favorable under treatment for 5 patients, while 7 patients became sicker and 5 finally died. CONCLUSION: Cryoglobulinemia is underdiagnosed. Treatment depends on the severity of the lesions and the underlying disease.

[Lupus and pregnancy: study of 26 cases, an internal medicine department experience and review of the literature]. / Lupus et grossesse : expérience d'un service de médecine interne à propos de 26 cas et revue de la littérature.

OBJECTIVE: To study the maternal and fetal outcomes in women with systemic lupus erythematosus. PATIENTS AND METHODS: A retrospective study of 26 pregnancies in 15 systemic erythematosus patients diagnosed before or during pregnancy regarding to American College of Rheumatology criteria in a single reference center. RESULTS: The mean patient age was 31.52 years (24-39 years). The mean interval from the diagnosis of the systemic lupus erythematosus to pregnancy was 4.2 years. Eight pregnancies were planned. The flare rate of lupus during pregnancy was 31%, life birth rate was 65% and fetal loss rate was 35%. DISCUSSION AND CONCLUSION: As an increase in disease activity can occur during pregnancy and because of a higher rate of obstetrical complications in patients with lupus, it is important to carefully plan pregnancy. Pregnancy in lupus patients must be closely monitored by a multispeciality care of the patients.

[Late revelation of homocysteinuria: clinical, biological and progressive aspects]. / Homocystéinurie à révélation tardive : aspect clinique, biologique et évolutif.

UNLABELLED: Homocysteinuria is a metabolic disorder with defect in genes encoding for methionine metabolism enzymes. The clinical features consist in: ophthalmic, neurological, orthopedic and vascular manifestations. It is generally diagnosed in childhood. Vascular involvements characterize adult's forms. We report one case. OBSERVATION: A 26-year-old man, who has lentis ectopia and a recent epilepsy, was hospitalized for deep vein thrombosis. Regarding the marfanoid phenotype and the high level homocysteinemia (231 micromol/L), homocysteinuria was suspected. Amino acid chromatography and reduced CBS activity were used to confirm the diagnosis. Vitamin enriched diet with vitamin B6 and folates has reduced slightly the homocysteine level. CONCLUSION: Homocysteinuria must be diagnosed early since a simple vitamin supply could ameliorate prognosis and decrease complications.

[Particularities of visceral leishmaniasis in adults not infected by HIV in Tunisia]. / Particularités de la leishmaniose viscérale de l'adulte non infecté par le VIH en Tunisie.

The incidence of adult visceral leishmaniasis in Tunisia has increased in recent years. As a result the epidemiological profile of the disease in our country is now closer to those observed in other Mediterranean countries. Most of the increase involves adults not infected by human immunodeficiency virus (HIV) although 56% of patients presented concurrent disease. In comparison with pediatric visceral leishmaniasis, adult disease is characterized by inconsistence occurrence of some major symptoms such as fever and spleen enlargement. For this reason the clinical disease syndrome may be incomplete and diagnosis may be difficult. Laboratory tests are essential for definitive diagnosis. Although no test is specific, some findings are highly useful, e.g, elevated g-globulins which was observed in 94% of patients in our series. Standard serology is less sensitive in adults with 18% of false negatives in our series probably as a result of immunodeficiency in some patients.

Autoantibodies to ribosomal P proteins in systemic lupus erythematosus.

UNLABELLED: Autoantibodies to ribosomal P proteins (anti-P) are directed against three ribosomal phosphoproteins (P0, P1, and P2) and are believed to be specific markers for systemic lupus erythematosus (SLE), particularly with neuropsychiatric manifestations. The objective of this study was to determine the rate of occurrence and clinical significance of anti-P in Tunisian patients. METHODS: We included 100 Tunisian patients with SLE whose sera were received between January 1998 and December 2000 by the immunology laboratory of the Charles Nicolle Teaching Hospital in Tunis, Tunisia, and were tested for anti-P. An immunodot technique based on a synthetic protein shared by all ribosomal phosphoproteins was used. RESULTS: Sera from 22 (22%) patients were positive for anti-P. This rate is consistent with the literature. We found no statistically significant associations between anti-P and specific manifestations of SLE. CONCLUSION. We found that anti-P were significantly associated with anti-Sm and anti-RNP, as reported previously. The significance of these associations remains debatable.

[The etiology of hypercalcemia: a study of 47 cases in a hospital internal medicine service]. / Les etiologies de l'hypercalcemie: etude a propos de 47 cas dans un service de medecine interne.

In this study, we are presented the clinical and the aetiologic features of 47 patients having hypercalcemia (total serum calcium > or = 2.7 mmol/l). Our results show a positive significantly correlation between the degree of the hypercalcemia and the severity of the clinical symptomatology. As for to the aetiology, the multiple myeloma, the hyperparathyroid and the neoplastic process constituted 78% of the total aetiology.

[Hemoptysis caused by pulmonary arterial aneurysm, disclosing Behçet disease. Apropos of 2 cases]. / Hémoptysie par anévrysme artériel pulmonaire (AAP), révélatrice d'une maladie de Behçet. A propos de deux cas.

Behçet's disease, frequent in our region, can have many clinical presentations. Arterial lesions generally lead to poor prognosis. We report two cases of pulmonary artery aneurysm in two young adults whose Behçet's disease was revealed by hemoptysia.
