A 57-year-old man with a long-standing history of gout and non-standard medication for 15 years, and habits of smoking and drinking for 40 years was admitted to our hospital. His discomfort included recurrent and progressive acute pain and motion limit of the knees. The physical examination revealed mildly red, swelling, and tender knees with reduced ROM (range of motion) of -20° to 60° (extension to flexion). Classic tophuses were found on both first metatarsal-phalangeal joint. Laboratory and radiographic tests revealed hyperuricemia (890 μmol/l, normal range 120-420 μmol/l), monosodium urate crystals, and degenerative joint features. The patient received a diagnosis of gouty knee arthritis, which is an indication for total knee arthroplasty. During the surgery, extensive tophi, white lime-like sediment of urine acid crystals, were discovered covering the articular facets of femur and tibia. The patient successfully discharged from the hospital with advice of lifestyle improvement and standard medication of gout suppressant.

Home Structure as Predictor of Adolescents’ Autonomy Development in the Assin South District, Ghana by*Anthony Edward Boakye PhD Candidate in Journal of Clinical Case Reports, Medical Images and Health Sciences

Home Structure as Predictor of Adolescents’ Autonomy Development in the Assin South District, Ghana  by Anthony Edward Boakye PhD Candidate in Journal of Clinical Case Reports, Medical Images and Health Sciences  Abstract  : Background: Too many rules or too forceful implementation of these rules, as well as too many consequences for not following the rules, can make adolescents feel that they are being oppressed rather than supported. This study investigates the home structure and adolescents’ autonomy development in the Assin South District, Ghana.  Methods: A cross-sectional descriptive design was used with 400 participants which comprised parents age 30-59 and older adolescents age 15-19 years. Data were analysed using frequency distribution, Pearson’s chi-squared test of independence and binary logistic regression.   Results: Association was found between parents knowing their child’s whereabout at p=0.034, (x²=4.493). Parents’ consistency in rules enforc...

Central Nervous System Melanomatosis Arising In Braf V600e Mutated Neurocutaneous Melanosis: A Case Report by Barbara Valeri by Journal of Clinical Case Reports, Medical Images and Health Sciences

Central Nervous System Melanomatosis Arising In Braf V600e Mutated Neurocutaneous Melanosis: A Case Report by Barbara Valeri in Journal of Clinical Case Reports, Medical Images and Health Sciences Abstract: Neurocutaneous melanosis (NCM) is a rare congenital syndrome defined by the combination of large or giant congenital melanocytic nevi and leptomeningeal melanocytic proliferation. NCM harbors per se an increased risk, as high as 12%, of malignant transformation to melanoma, arising in the context of either the congenital nevi or the central nervous system. The vast majority (75%) of NCM is a result of somatic mosaicism due to a single postzygotic mutation involving NRAS codon 61, which can be found both in skin and central nervous system localizations. BRAF V600E mutation is present only in a minority of patients with NCM (~12.5%). Here we report the rare case of a BRAF V600E mutated NCM complicated by central nervous system melanomatosis, defined as a diffuse or multifocal meninge...

A Case of Gastrointestinal Bleed due to Angiodysplasia in Primary Care treated with Thalidomide by Samar Zaki in Journal of Clinical Case Reports, Medical Images and Health Sciences

A Case of Gastrointestinal Bleed due to Angiodysplasia in Primary Care treated with Thalidomide by Samar Zaki in Journal of Clinical Case Reports, Medical Images and Health Sciences Abstract: Angiodysplasia is an important and frequent cause of long-term intermittent gastrointestinal (GI) bleed in elderly patients. Gastrointestinal angiodysplasia (GIAD) is one of the most common cause in the elderly, while tumors dominate in younger individuals (below 50 years of age). GIAD can present as hematochezia, malena or as iron deficiency anemia with intermittently positive occult blood in stools. Several methods have been invented and tried with no desired outcomes. Recurrent symptoms and requirement for blood transfusions despite endoscopic therapy necessitate the evaluation for a pharmacological intervention. Medical management in the past comprised of hormonal therapy and octreotide. The use of thalidomide for recurrent GIAD is not common thus in our case study we describe the use of th...
