Metformin Hydrochloride is an antidiabetic used for many years, currently; it considered the first choice in treatment of type 2 diabetes (T2D). It decreases insulin resistance, doesn't induce hypoglycaemia, increases glucose utilization in the liver and skeletal muscle, and decreases hepatic glucose production. Its adverse effects (AE) are gastrointestinal, decrease in vitamin B12 absorption, abnormalities of hemogram and rarely skin reactions. The objective of this study was to report the type and frequency of AEs of Metformin Hydrochloride used in the therapeutic management of T2D patients admitted to the medical center and the diabetes home of Sidi Bel-Abbès in Algeria.

Although the incidence of syphilis reached a historic low in 2000, the number of incident cases has since increased in men and women across the USA. In 2019, men who have sex with men (MSM) accounted for 57% of all primary and secondary (P&S) syphilis cases, and about half of MSM with P&S syphilis are living with human immunodeficiency virus (HIV) infection. Days after infection, Treponema pallidum disseminates and invades tissues distant from the site of inoculation. Once the spirochete disseminates, the host develops an inflammatory response; diagnosis requires a high level of suspicion since syphilis may affect the skin, musculoskeletal, cardiovascular, and central nervous systems. We report a 61-year-old man with virally suppressed HIV infection who presented with polyarthralgia, chest pain, and weight loss, diagnosed with secondary syphilis, manifesting with ankle inflammatory arthritis and bone involvement, of the calvarium and manubrium. Early and late syphilis in adults can manifest with articular and periarticular pathologies, including inflammatory arthritis, tenosynovitis, periostitis, and myositis. Higher clinical suspicion is needed for prompt diagnosis of syphilis in patients who are at risk and suspected of having an autoimmune disease. This report includes a review of the musculoskeletal manifestations of syphilis.

The objective of this case study is to describe the history, presentation, treatment, and outcome of a patient receiving manipulation under anesthesia (MUA) followed by prolotherapy for adhesive capsulitis and rotator cuff tear.

Microvascular occlusions caused by sickle cell disease (SCD) can affect all ocular and orbital structures. Sickle cell retinopathy (SCR) is the most common ophthalmic manifestation of SCD. Fortunately, most individuals with SCR are visually asymptomatic. Vision loss in SCD most commonly occurs as a consequence of proliferative sickle cell retinopathy (PSR), in which pathologic retinal neovascularization occurs. To prevent significant vision loss and blindness, which can occur from complications of PSR, regular retinopathy surveillance screening examinations and consistent follow-up with a retina specialist are recommended. Scatter laser photocoagulation is the current gold-standard treatment to prevent vision threatening progression of PSR. Patients with sickle cell disease should have regular checkups with their dental care provider. Patients should be educated on the importance of proper dental care, a healthy diet, and the need for early intervention if they suspect any dental problems or are having dental pain. If any dental procedures that involve surgery or sedation are planned, it is critical to consult with the hematologist before the procedure is started. Prophylactic antibiotics may have to be prescribed before invasive dental procedures, such as extractions or periodontal surgery but is best determined by discussions between the dental care provider and the hematologist. Osteonecrosis is a highly prevalent skeletal complication of sickle cell disease that affects all genotypes. Risk factors for osteonecrosis include older age, HbSS genotype with concomitant alpha-thalassemia trait, frequent vaso-occlusive episodes, history of acute chest syndrome, elevated body mass index, and low white blood cell counts. Osteonecrosis causes progressive joint damage and associates with chronic pain, frequent acute care visits, and overall poor health-related quality of life. Current consensus guidelines recommend analgesics, physical therapy, and early consideration of joint arthroplasty in sickle cell-related osteonecrosis, although surgery may be deferred until late adolescence after growth plates have fused.

Single coronary artery (SCA) is a very rare coronary artery anomaly of origin and course with a reported prevalence of only 0.024%-0.066% among patients undergoing routine coronary angiography. The majority of the individuals remain asymptomatic and thus SCA is found only incidentally on conventional or computed tomography coronary angiography done for other reasons. A minority of the patients may have non-specific cardiac symptoms (such as ischemic pain, tachycardia, etc.) or even sudden death. SCA can occur in isolation or in association with other congenital cardiac defects like such as persistent truncus arteriosus, tetralogy of Fallot (TOF), pulmonary atresia, transposition of great vessels (TGA), ventricular septal defect (VSD), coronary arteriovenous fistula (AVF), patent foramen ovale (PFO) and bicuspid aortic valve. We present a case of 50 years male with incidental finding of SCA arising from the left coronary sinus which had an inter-arterial course before branching (SCA Type: LIIB based on the Lipton-Yamanaka classification) which was revealed on computed tomography coronary angiography (CTCA) performed after the patient complained of infrequent chest pain. Management of the diagnosed cases can be either conservative, stent placement or surgical correction based on the symptomatology and clinico-lab findings.

The purpose of this study was to prepare GeXIVA[1,2] PLGA microspheres by W/O/W re-emulsification-solvent evaporation technology and to develop sustained-release formulations to meet the clinical treatment needs of chronic neuropathic pain. Through prescription optimization, the uniformity of particle size and the encapsulation efficiency is improved, so as to achieve the quality standard of the microspheres. The mechanism of trehalose improving the stability of GeXIVA[1,2] was studied and verified by molecular simulation. The results showed that when adding trehalose to W1, using the PLGA model of 75:25, PLGA concentration of 30%, PVA concentration of 1.5%, adding 1% NaCl to PVA and adding 1% NaCl to solidification water, the prepared microspheres are smooth, the particle size is about 25 μm, and the encapsulation rate reaches 90%. The results of in vitro release experiments showed that the microspheres could be released steadily for about 30 days. The microsphere samples were characterized and analyzed by molecular simulation and powder X-ray diffractometer, and the protective mechanism of trehalose on GeXIVA[1,2] was discussed. The results showed that the hydrogen bond formed between trehalose and GeXIVA[1,2] acted as a hydration film and played a certain protective role on GeXIVA[1,2]. In addition, high-viscosity trehalose can form a glass state and wrap around GeXIVA[1,2], reducing the free movement of molecules. In the microsphere system, trehalose can also avoid the influence of PLGA material on the secondary structure of GeXIVA[1,2]. In conclusion, this study is expected to provide a new therapeutic strategy for the treatment of chronic neuropathic pain.

Rheumatoid arthritis is a chronic systemic autoimmune disease that results in symmetrical inflammatory polyarthritis with extra-articular involvement, including skin manifestations. It targets the lining of the synovial membranes and is treated with disease-modifying antirheumatic drugs. If left untreated, it leads to increased morbidity, mortality, and socioeconomic burdens. Tocilizumab is a humanized monoclonal antibody that binds to interleukin-6 receptors and is used to treat rheumatoid arthritis in patients with inadequate response to conventional synthetic therapy. This medication can cause adverse dermatologic events, such as urticaria, pruritus, and mild maculopapular rash. In this case, we report a 39-year-old woman with rheumatoid arthritis who developed tocilizumab-induced dermatosis.
