Services show a return to growth

The corrugated economy continues.

The third of the UK PMIs has come in today (After construction fell and manufacturing rose), and the service sector is also seeing a return to growth, with the index recording a level of 51.5 (where 50 is equal to no change).

Markit economics, which produces the index, writes:

A return to growth of the UK service sector was signalled at the start of 2013 as volumes of incoming new business increased and companies boosted capacity by adding to their payrolls.

Confidence in the future also strengthened, reaching an eight-month high, but margins continued to be squeezed as output charges rose at a considerably slower rate than input costs.

Combined with the other PMIs, the picture remains far from rosy, but at least the UK appears to be stagnating rather than actively shrinking. It fits with the view of the economy becoming corrugated — flipping from mild growth to mild contraction with the overriding trend being stagnating. The all-sectors PMI, which aggregates the information in the previous releases, ought to confirm that tomorrow.

With services the most important sector of the UK economy — for better or worse — the return to growth is a "huge sigh of relief" according to Markit's chief economist Chris Williamson:

Stronger growth would inevitably have been recorded had the country not suffered the heavy snowfall, suggesting the underlying trend is even stronger than these numbers indicate.

With services companies’ confidence also picking up, new business rising for the first time in three months and hiring growing at the fastest rate for six months, the sector looks to be on a renewed upswing which should help the economy grow again in the first quarter.

The surprising truth about ingrowing toenails (and other medical myths)

Medicine is littered with myths. For years we doled out antibiotics for minor infections, thinking we were speeding recovery.

From time to time, I remove patients’ ingrowing toenails. This is done to help – the condition can be intractably painful – but it would be barbaric were it not for anaesthesia. A toe or finger can be rendered completely numb by a ring block – local anaesthetic injected either side of the base of the digit, knocking out the nerves that supply sensation.

The local anaesthetic I use for most surgical procedures is ready-mixed with adrenalin, which constricts the arteries and thereby reduces bleeding in the surgical field, but ever since medical school I’ve had it drummed into me that using adrenalin is a complete no-no when it comes to ring blocks. The adrenalin cuts off the blood supply to the end of the digit (so the story goes), resulting in tissue death and gangrene.

So, before performing any ring block, my practice nurse and I go through an elaborate double-check procedure to ensure that the injection I’m about to use is “plain” local anaesthetic with no adrenalin. This same ritual is observed in hospitals and doctors’ surgeries around the world.

So, imagine my surprise to learn recently that this is a myth. The idea dates back at least a century, to when doctors frequently found digits turning gangrenous after ring blocks. The obvious conclusion – that artery-constricting adrenalin was responsible – dictates practice to this day. In recent years, however, the dogma has been questioned. The effect of adrenalin is partial and short-lived; could it really be causing such catastrophic outcomes?

Retrospective studies of digital gangrene after ring block identified that adrenalin was actually used in less than half of the cases. Rather, other factors, including the drastic measures employed to try to prevent infection in the pre-antibiotic era, seem likely to have been the culprits. Emboldened by these findings, surgeons in America undertook cautious trials to investigate using adrenalin in ring blocks. They found that it caused no tissue damage, and made surgery technically easier.

Those trials date back 15 years yet they’ve only just filtered through, which illustrates how long it takes for new thinking to become disseminated. So far, a few doctors, mainly those in the field of plastic surgery, have changed their practice, but most of us continue to eschew adrenalin.

Medicine is littered with such myths. For years we doled out antibiotics for minor infections, thinking we were speeding recovery. Until the mid-1970s, breast cancer was routinely treated with radical mastectomy, a disfiguring operation that removed huge quantities of tissue, in the belief that this produced the greatest chance of cure. These days, we know that conservative surgery is at least as effective, and causes far less psychological trauma. Seizures can happen in young children with feverish illnesses, so for decades we placed great emphasis on keeping the patient’s temperature down. We now know that controlling fever makes no difference: the fits are caused by other chemicals released during an infection.

Myths arise when something appears to make sense according to the best understanding we have at the time. In all cases, practice has run far ahead of objective, repeatable science. It is only years after a myth has taken hold that scientific evaluation shows us to have charged off down a blind alley.

Myths are powerful and hard to uproot, even once the science is established. I operated on a toenail just the other week and still baulked at using adrenalin – partly my own superstition, and partly to save my practice nurse from a heart attack. What would it have been like as a pioneering surgeon in the 1970s, treating breast cancer with a simple lumpectomy while most of your colleagues believed you were being reckless with your patients’ future health? Decades of dire warnings create a hefty weight to overturn.

Only once a good proportion of the medical herd has changed course do most of us feel confident to follow suit.
