Carpal tunnel syndrome (CTS) is caused by compression of the median nerve as it travels through the carpal tunnel. Patients commonly experience pain, paresthesia, and, less often, weakness in the distribution of the median nerve. Provocative maneuvers, such as the Phalen test and Tinel sign, have varying sensitivity and specificity for the diagnosis of CTS. Thenar atrophy is a late finding and highly specific for CTS. Although patients with a classic presentation of CTS do not need additional testing for diagnosis, electrodiagnostic studies can confirm the diagnosis in atypical cases, exclude other causes, and gauge severity for surgical prognosis. An abnormal nerve conduction study is useful for ruling in CTS, but a normal test does not necessarily exclude it. Over-the-counter analgesics, such as nonsteroidal anti-inflammatory drugs and acetaminophen, have not shown benefit for CTS. Patients with mild to moderate CTS initially may be offered nonsurgical treatments, such as splinting or local corticosteroid injections. Night-only splinting is as effective as continuous wear. A neutral wrist splint may be more effective than an extension splint. In patients with recent onset of CTS, corticosteroid injections provide slightly greater improvement of symptoms compared with splinting at 6 weeks, with similar outcomes at 6 months. Patients with severe CTS, including objective weakness or sensory deficits, should be offered surgical decompression. Endoscopic and open carpal tunnel release techniques are equally effective.

Hidradenitis suppurativa is a chronic folliculitis affecting intertriginous areas. Onset generally occurs in young adulthood to middle adulthood (18 to 39 years of age). Females and blacks are more than twice as likely to be affected. Additional risk factors include family history, smoking, and obesity. Hidradenitis suppurativa is associated with several comorbidities, including diabetes mellitus and Crohn disease. The clinical presentation of hidradenitis suppurativa ranges from rare, mild inflammatory nodules to widespread abscesses, sinus tracts, and scarring. Quality of life is often affected, and patients should be screened for depression. Treatment includes wearing loose-fitting clothes, losing weight if overweight, and smoking cessation. Topical clindamycin alone can be effective for patients with mild disease. Patients with moderate disease can be treated with oral antibiotics, such as tetracyclines, in addition to topical clindamycin. Adalimumab, a tumor necrosis factor alpha inhibitor, is effective for patients with moderate to severe hidradenitis suppurativa. Surgical procedures are often necessary for definitive treatment and include local procedures, such as punch debridement and unroofing/deroofing. Wide excision is indicated for patients with severe, extensive disease and scarring.

Human papillomavirus infection is the precursor for the development of cervical cancer and is detectable in 99.7% of squamous cell carcinoma and adenocarcinoma cases. Early detection of precancerous lesions with Papanicolaou testing remains the primary mechanism for cancer prevention. Once cervical cancer is diagnosed, treatment may involve surgery, radiation therapy, chemotherapy, or a combination. The choice of therapy depends on the stage of disease, lymph node involvement, patient comorbidities, and risk factors for recurrence. Early-stage, microinvasive disease may be treated with surgery alone if margins are negative and there is no lymph node involvement; adjuvant chemoradiation should be considered for other early-stage disease. Locally advanced disease is often treated with chemoradiation. The addition of bevacizumab, an antivascular endothelial growth factor monoclonal antibody, to combination chemotherapy improves survival among patients with recurrent, persistent, or metastatic cervical cancer. Disease stage and lymph node involvement are the most prognostic factors. Pregnancy status and desire to preserve fertility should be considered when developing a treatment strategy. After treatment, close follow-up with a gynecologist-oncologist for pelvic examinations at regular intervals is recommended to assess for recurrence.

Carpal tunnel syndrome, the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel. Classically, patients with the condition experience pain and paresthesias in the distribution of the median nerve, which includes the palmar aspect of the thumb, index and middle fingers, and radial half of the ring finger. Additional clues include positive physical examination findings, such as the flick sign, Phalen maneuver, and median nerve compression test. Although patients with typical symptoms and signs of carpal tunnel syndrome do not need additional testing, ultrasonography and electrodiagnostic studies are useful to confirm the diagnosis in atypical cases and rule out other causes. If surgical decompression is planned, electrodiagnostic studies should be obtained to determine severity and surgical prognosis. Conservative treatment may be offered initially to patients with mild to moderate carpal tunnel syndrome. Options include splinting, corticosteroids, physical therapy, therapeutic ultrasound, and yoga. Nonsteroidal anti-inflammatory drugs, diuretics, and vitamin B6 are not effective therapies. Local corticosteroid injection can provide relief for more than one month and delay the need for surgery at one year. Patients with severe carpal tunnel syndrome or whose symptoms have not improved after four to six months of conservative therapy should be offered surgical decompression. Endoscopic and open techniques are equally effective, but patients return to work an average of one week earlier with endoscopic repair.
