I am reporting on an interesting occurrence related to diving. On the first day of diving on a recent trip (approximately 24 hours after having deplaned) a female diver (experienced, dives year around, age ca. 40) completed 3 dives in warm water (26-27 deg C). Computer: Legend (Buhlman) Conditions: close to ideal flat calm, good viz current, but dive was a 'drift dive'. Dive 1 90ft 22 min slow ascent followed by 3 min stop @ 15ft. SIT - 36 min Dive 2 60ft 30 min 3 min stop. SIT - 35 min Dive 3 60ft 30 min, ..3 min stop Following the dives, within 2 hours, diver was noticed to not be 'self'. Inquiry produced two signs: 1. An ocular disorder mimicking those experienced in past independent of diving. 2. Tenderness in breast to the extent that they were uncomfortable/sore. Diver was on the last day of her menses. (at that point, no visible signs noticed. Showered & donned supportive bra. Complete relief in approx 2-3 hrs) The next morning diver did two more dives of 60 ft of 40 min each with SIT = The same pattern of dives were completed in the afternoon. Details of all for dives of that day follow. . 60 ft for 30 min..3 min stop SIT - 38 min 56 for 32 , 3 min stop SIT 2hr 35 min 59 for 30 , 3 min stop SIT 37 61 for 25 - minimal stop After 2nd dive, breasts were very painful After last dive, noticed that Breasts were swollen with patchy redness and visible veins. Diver recalls no relief of pain during last 2 dives (while under pressure). Ocular disorders did recur, lasted 30 min. When S&S were present early the third morning the question of DCI with lymphatic involvement was raised and DAN contacted. DAN counseled diver to seek hyperbaric medical consult, though they had not heard of such an occurrence. Patient was treated at a hyperbaric facility on USN Table 6 with no relief. Patient was discharged with a potential for contact dermatitis being the cause of the problem. Although an additional chamber ride was mentioned directly after the first, it was not addressed during subsequent conversation with physician. In addition, no further medical consult with a dermatologist or other specialist was suggested. Patient was advised to take anti-inflammatory medication. Patient took ibuprofen and aspirin as advised Patient did not dive for balance of trip and flew back (commercial airliner) approximately 100 h following the first dive of the trip. The S&S subsided over the next several days with final relief 6-7 days after first dive Further consults initially were not firm, but physician handling case upon arrival at city of residence (was not a hyperbarisist) sought a telephone consult with a hyperbaric fellow (originally said he was sure it was contact dermatitis). Based on the opinion of the latter, who had never seen or examined the patient, the final diagnosis at the follow-up facility was: Type II DCS with skin & lymphatic involvement. Thus, though two physicians had originally decided that this was not DCS, the final diagnosis was exactly that! An exact science it is not! Esat Atikkan
