distortions of the handClawing”—seen best with distal lesions of median or ulnar nerves. Remaining extrinsic flexors of the digits exaggerate the loss of the lumbricalsfingers extend at MCP, flex at DIP and PIP joints.

what nerve will be injured?femoral nerve
Femoral nerve mononeuropathy can occur due to trauma (eg, pelvic fracture), compression from a ☆hematoma or abscess, or injury during surgery/childbirth. Findings of femoral neuropathy include quadriceps weakness (eg, difficulty with stairs, falling due to knee buckling), decreased patellar reflex, and ☆sensory loss over the anterior and medial thigh and medial leg. musculoskeletalanatomyUWorld Jul 3, 2020, 6:20 PM HirotoShishido

kidney transplantThe native kidneys are typically left in place, and the donor kidney is placed retroperitoneally in the right iliac fossa.
Blood supply is established by anastomosing the donor renal artery with the recipient's ☆external iliac artery.
Although the transplanted ureter will continue to receive blood ☆through the donor's renal artery, the most distal portion may be susceptible to ischemia due to lack of anastomotic connections. renalanatomyUWorld Jun 27, 2020, 9:26 PM HirotoShishido

IVC(inferior vena cava) obstruction caused by RCC(renal cell carcinoma)IVC obstruction can occur due to intraluminal extension and thrombus formation, rather than mass effect from the tumor itself.
The obstruction can occur acutely or gradually over time. In chronic cases, collateral venous circulation may develop based on the site of the obstruction. Prominent abdominal wall collateral veins(☆tortuous abdominal veins), and ☆symmetric bilateral lower extremity pitting edema suggest obstruction of the upper segment of the IVC. renalanatomyUWorld Jun 6, 2020, 11:42 PM HirotoShishido

treatment for hyperhidrosisSystemic anticholinergic medications (eg, oxybutynin), local anticholinergic injectable medications (eg, botulinum toxin), or surgical sympathectomy may be used to treat hyperhidrois.
Surgical sympathectomy for primary focal hyperhidrosis of the axilla uses electrocoagulation to target the ☆thoracic sympathetic trunk at the T2 sympathetic segment.
