The elusive bipartite scaphoid: a rare congenital variant or misdiagnosed pseudoarthrosis? A proposal for novel radiological criteria.

Variations in the development of carpal bones are uncommon, with the scaphoid bone typically forming from the fusion of the os centrale carpi and the radial chondrification center during embryogenesis. A bipartite scaphoid is a rare congenital disorder that occurs when these ossification centers fail to fuse, with a prevalence ranging from 0.1% to 0.

Morphological variability of the testicular arteries and clinical significance - a comprehensive review.

The testicular artery is the vessel that provides oxygen-rich blood to the testes. It is also involved in many more processes that play important roles in spermatogenesis such as thermoregulation. As the vessel has a number of anatomical variants, it may be often responsible for difficulties and complications during abdominopelvic surgical procedures.

Diagnostic Challenges in Malignant Hyperthermia and Anesthesia-Induced Rhabdomyolysis: A Case Study.

BACKGROUND Malignant hyperthermia (MH) and anesthesia-induced rhabdomyolysis (AIR) are rare, yet life-threatening complications that need prompt therapeutic actions and logistic preparedness for treatment success. Both conditions are triggered by general anesthetics, particularly volatiles and depolarizing muscle relaxants. In comparison with MH, which is an inherited pharmacogenomic disease of calcium channel receptor subpopulation and arises only after trigger exposure, AIR has been described mostly in patients with muscular dystrophies.

The extensor digitorum brevis manus variability and clinical significance: a systematic review with meta-analysis.

Purpose: The current meta-analysis aimed to investigate the extensor digitorum brevis manus (EDBM) muscle variability by calculating the pooled prevalence of all published variants. After considering the pooled prevalence, these variants were classified based on their insertion and relationship with the extensor indicis (EI) muscle and/or tendon. The origin of the variants, neural and arterial supply, and the terminology of the EDBM variants were further investigated.

Periprosthetic Joint Infection Caused by Providencia stuartii: A Case Report.

Periprosthetic joint infection (PJI) is a rare yet serious complication following a total hip replacement, predominantly caused by gram-positive bacteria such as and However, gram-negative pathogens can also be isolated. This case report presents a 22-year-old patient with a PJI caused by after total hip replacement due to a motor vehicle accident. The patient with a clinical history of total hip replacement secondary to posttraumatic arthrosis presented to our department with clinical and laboratory indications of PJI in the right hip.

Uncommon Manifestations of Lung Cancer: Diagnostic Challenges and Valuable Insights From a Rare Clinical Case.

Lung cancer is commonly diagnosed at advanced stages, often presenting with metastases. Although bone metastases are common in lung cancer patients, acrometastases - metastatic lesions in the bones of the hand - are exceedingly rare. Herein, we report the case of a 71-year-old male with previously undiagnosed lung adenocarcinoma, which first manifested as a painful swelling in the right hand.

A Complex Case of Bilateral Carpal Tunnel Syndrome in a Patient With Gout: A Case Report and Review of Literature.

Carpal tunnel syndrome (CTS) is the most common nerve entrapment condition of the upper extremity, primarily caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. While various factors can lead to this condition, the accumulation of gouty tophi in the flexor tendons is a rare cause. This case involves a 57-year-old manual laborer who presented with progressively worsening symptoms in both hands, including numbness, pain, and muscle weakness, which were more severe in his right hand.

Unraveling the Complex Molecular Interplay and Vascular Adaptive Changes in Hypertension-Induced Kidney Disease.

Angiogenesis, the natural mechanism by which fresh blood vessels develop from preexisting ones, is altered in arterial hypertension (AH), impacting renal function. Studies have shown that hypertension-induced renal damage involves changes in capillary density (CD), indicating alterations in vascularization. We aimed to elucidate the role of the apelin receptor (APLNR), neuronal nitric oxide synthase (nNOS), and vascular endothelial growth factor (VEGF) in hypertension-induced renal damage.

Multiple scapula defects or foramina or both?

The current bone report describes multiple openings identified in a dried scapula of a subject of unknown age and gender. Multiple openings (twelve) were identified in the subscapular fossa and were apparent at the infraspinatus fossa. These openings coexisted with a suprascapular foramen and an osteophyte at the inferomedial border of the foramen.

The superior thyroid artery origin pattern: a systematic review with meta-analysis.

Purpose: The current systematic review with meta-analysis aimed to investigate the pooled prevalence of the superior thyroid artery (STA) pattern of origin (distinct or fused-common origin with adjacent arteries in the form of a common trunk). The standard and uncommon variants were also studied, considering the STA's exact surface of origin and the relationship with the upper border of the thyroid cartilage (TC, reference point), considering the laterality effect. Thus, the STA topographical anatomy was considered.

An accessory head of the extensor indicis: a rare case report.

Purpose: A deep knowledge of the variations of the posterior forearm musculature is crucial for assessing and diagnosing conditions in this region. Extensor indicis (EI) is one of the muscles in this region, which exhibits diverse anatomical variations. This report documents an extremely unusual form of the EI with an accessory head on the dorsum of the hand.

Please be very careful, when describing variant muscle.

A Rare Case of Large Lateral Chest Wall Hibernoma.

Hibernomas, rare benign tumors originating from brown adipose tissue, pose diagnostic challenges due to their infrequent occurrence and slow growth. We present a case of a 38-year-old woman with a progressively enlarging mass in her right lateral chest wall, initially stable in size but growing during pregnancy and causing pain and functional impairment. Radiological evaluation, including x-ray and MRI, provided inconclusive results, necessitating a biopsy for a definitive diagnosis.

A bicaudatus sartorius muscle: a rare variant with potential clinical implications.

Background: Sartorius muscle (SM) belongs to the thigh anterior compartment musculature. It corresponds to the longest muscle of the human body, while its variations are described rarely. The current case reports aims to describe a distal bifurcation of the SM, forming the bicaudatus SM variant.

Giant Ossifying Lipoma of the Hand: A Case Report and Review of Literature.

Lipomas are one of the most common benign tumors of the body, characterized by a slow-growing, painless mass that rarely causes symptoms. Bone metaplasia among the mature adipose cells, however, is a rare condition called osteolipoma. In this article, we present a case report of a 61-year-old lady with a giant osteolipoma of the hand.

Are There Any Differences in the Healing Capacity between the Medial Collateral Ligament's (MCL) Proximal and Distal Parts in the Human Knee? Quantitative and Immunohistochemical Analysis of CD34, α-Smooth Muscle Actin (α-SMA), and Vascular Endothelial Growth Factor (VEGF) Expression Regarding the Epiligament (EL) Theory.

The human knee is a complex joint that comprises several ligaments, including the medial collateral ligament (MCL). The MCL provides stability to the knee and helps prevent its excessive inward movement. The MCL also has a thin layer of connective tissue known as the epiligament (EL), which adheres to the ligament.

Squamous Cell Carcinoma of the Thumb: A Case Report.

Squamous cell carcinoma (SCC) is the most common tumor of the hand with a high tendency for local recurrence and a low rate of metastasis. Herein, we present an interesting case of SCC of the thumb of the right hand in a 68-year-old patient with one recurrence, treated with surgical excision and following radiotherapy. Five years postoperative, there are no clinical and imaging data for local recurrence, as well as the presence of metastases.
